     (b) If (i) by March 5, 2005, the Shelf Registration Statement has not been amended to cover

or usable, and (iv) the aggregate duration of any suspension periods in any period exceeds certain
limits described in the Registration Rights Agreement (each such event referred to in clauses (i),
(ii), (iii) and (iv) a “Registration Default”), additional dividends shall accumulate on the
Preferred Stock, from and including the date on which any such Registration Default shall occur to,
but excluding, the date on which the Registration Default has been cured, at the rate of 0.25% per
year for the first 90 days following such date and at a

rate of 0.50% per year thereafter (“Additional Dividends”). With respect to shares of Common Stock
issued upon conversion of the Preferred Stock, Additional Dividends will accumulate on the then
applicable conversion price from and including the date on which any such Registration Default
shall occur to, but excluding, the date on which the Registration Default has been cured, at the
rate of 0.25% per year for the first 90 days following such date and at a rate of 0.50% per year
thereafter. Except as mentioned above, the Corporation will have no other liabilities for monetary
damages with respect to its registration obligations. The receipt of Additional Dividends will be
the sole monetary remedy available to a Holder if the Corporation fails to meet these obligations.

     (c) No dividend will be declared or paid upon, or any sum set apart for the payment of
dividends upon, any outstanding share of the Preferred Stock with respect to any dividend period
unless all dividends for all preceding dividend periods have been declared and paid or declared and
a sufficient sum set apart for the payment of such dividend upon all outstanding shares of
Preferred Stock.

     (d) No dividends or other distributions (other than a dividend or distribution payable solely
in shares of Parity Stock or Junior Stock (in the case of Parity Stock) or Junior Stock (in the
case of Junior Stock) and other than cash paid in lieu of fractional shares) may be declared, made
or paid, or set apart for payment upon, any Parity Stock or Junior Stock, nor may any Parity Stock
or Junior Stock be redeemed, purchased or otherwise acquired for any consideration (or any money
paid to or made available for a sinking fund for the redemption of any Parity Stock or Junior
Stock) by or on behalf of the Corporation (except by conversion into or exchange for shares of
Parity Stock or Junior Stock (in the case of Parity Stock) or Junior Stock (in the case of Junior
Stock)), unless full Accumulated Dividends shall have been or contemporaneously are declared and
paid, or are declared and a sum sufficient for the payment thereof is set apart for such payment,
on the Preferred Stock and any Parity Stock for all dividend payment periods terminating on or
prior to the date of such declaration, payment, redemption, purchase or acquisition.
Notwithstanding the foregoing, if full dividends have not been paid on the Preferred Stock and any
Parity Stock, dividends may be declared and paid on the Preferred Stock and such Parity Stock so
long as the dividends are declared and paid pro rata so that the amounts of dividends declared per
share on the Preferred Stock and such Parity Stock will in all cases bear to each other the same
ratio that accumulated and unpaid dividends per share on the shares of Preferred Stock and such
other Parity Stock bear to each other.

     (e) Holders of shares of Preferred Stock shall not be entitled to any dividends on the
Preferred Stock, whether payable in cash, property or stock, in excess of full cumulative dividends
and Additional Dividends (if any).

     (f) The holders of shares of Preferred Stock at the close of business on a Dividend Record
Date will be entitled to receive the dividend payment on those shares on the corresponding Dividend
Payment Date
notwithstanding the subsequent conversion thereof or the Corporation’s default in payment of
the dividend due on that Dividend Payment Date. However, shares of Preferred Stock surrendered for
conversion during the period between the close of business on any Dividend Record Date and the
close of business on the Business Day immediately preceding the applicable Dividend Payment Date
must be accompanied by payment of an amount equal to the dividend payable on the shares on that
Dividend Payment Date; provided, however, that no such payment need be made if (1) the Corporation
has specified a Mandatory Conversion Date that is after a Dividend Record Date and on or prior to
the immediately following Dividend Payment Date or (2) any accumulated and unpaid dividends exist
at the time of conversion with respect to such shares of Preferred Stock to the extent of such
accumulated and unpaid dividends. A holder of shares of Preferred Stock on a Dividend Record Date
who (or whose transferee) tenders any shares for conversion on the corresponding Dividend Payment
Date will receive the dividend payable by the Corporation on the Preferred Stock on that date, and
the converting holder need not include payment in the amount of such dividend upon surrender of
shares of Preferred Stock for conversion. Except as provided above with respect to a voluntary
conversion pursuant to Section 7, the Corporation shall make no payment or allowance for unpaid
dividends, whether or not in arrears, on converted shares or for dividends on the shares of Common
Stock issued upon conversion.

     (g) In any case where any Dividend Payment Date or Conversion Date (including upon the
occurrence of a Fundamental Change) of any Preferred Stock shall not be a Business Day, at any
place of payment, then payment of dividends (and Additional Dividends, if any) need not be made on
such date, but may be made on the next

8

 

succeeding Business Day at such place of payment with the same force and effect as if made on the
dividend payment date or Conversion Date (including upon the occurrence of a Fundamental Change);
and no dividends shall accumulate on the amount so payable for the period from and after such
Dividend Payment Date or Conversion Date, as the case may be, to such Business Day.

     (h) The Paying Agent shall return to the Corporation upon written request any money or
property held by it for the payment of any amount with respect to the Preferred Stock that remains
unclaimed for two years, provided, however, that the Paying Agent, before being required to make
any such return, shall at the expense of the Corporation cause to be published once in a newspaper
of general circulation in The City of New York or mail to each such Holder notice that such money
or property remains unclaimed and that, after a date specified therein, which shall not be less
than 30 days from the date of such publication or mailing, any unclaimed money or property then
remaining shall be returned to the Corporation. After return to the Corporation, Holders entitled
to the money or property must look to the Corporation for payment as general creditors unless an
applicable abandoned property law designates another Person.

     4. Fundamental Change.

     (a) Purchase at the Option of the Holder Upon a Fundamental Change. Each Holder shall have the
right, at such Holder’s option, to require the Corporation to purchase any or all of such Holder’s
Preferred Stock for cash or a check on the date that is no earlier than 60 days nor later than 90
days after the date of the Corporation Notice of the occurrence of such Fundamental Change (subject
to extension to comply with applicable law, as provided in Section 4(h) (the “Fundamental Change
Purchase Date”). The Preferred Stock shall be repurchased in integral multiples of $50.00
(representing the Liquidation Preference). The Corporation shall purchase such Preferred Stock at
a price (the “Fundamental Change Purchase Price”) equal to 100% of the Liquidation Price of the
number of shares of Preferred Stock to be purchased plus accumulated and unpaid dividends,
including Additional Dividends, if any, to the Fundamental Change Purchase Date.

     (b) Notice of Fundamental Change. The Corporation, or at its request (which must be received
by the Paying Agent at least three Business Days (or such lesser period as agreed to by the Paying
Agent) prior to the date the Paying Agent is requested to give such notice as described below), the
Paying Agent, in the name of and at the expense of the Corporation, shall mail to all Holders a
Corporation Notice of the occurrence of a Fundamental Change and of the purchase right arising as a
result thereof, including the information required by Section 4(e) hereof, on or before the 30th
day after the occurrence of such Fundamental Change.

     (c) Exercise of Option. For Preferred Stock to be so purchased at the option of the Holder,
the Paying Agent must receive at its office in Jackson, Michigan, or any other offices of the
Paying Agent maintained for such purposes, such shares of Preferred Stock duly endorsed for
transfer, together with a written notice of
purchase in the form attached hereto as Exhibit A (a “Fundamental Change Purchase Notice”)
duly completed, on or before the 30th day prior to the Fundamental Change Purchase Date, subject to
extension to comply with applicable law. The Fundamental Change Purchase Notice shall state:

	 	(i)	 	if certificated, the certificate numbers of the shares of Preferred Stock which the Holder
shall deliver to be purchased, or, if not certificated, the Fundamental Change Purchase Notice
must comply with appropriate Depository procedures;
	 
	 	(ii)	 	the number of shares of Preferred Stock which the Holder shall deliver to be purchased,
which portion must be $50.00 or an integral multiple thereof; and
	 
	 	(iii)	 	that such Preferred Stock shall be purchased as of the Fundamental Change Purchase Date
pursuant to the terms and conditions specified in the Preferred Stock and in this Certificate
of Designation.

     (d) Procedures. The Corporation shall purchase from a Holder, pursuant to this Section 4,
shares of Preferred Stock or multiples of $50.00 if so requested by such Holder.

9

 

     Any purchase by the Corporation contemplated pursuant to the provisions of this Section 4
shall be consummated by the delivery of the Fundamental Change Purchase Price to be received by the
Holder promptly following the later of the Fundamental Change Purchase Date or the time of
book-entry transfer or delivery of the Preferred Stock.

     Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Fundamental Change Purchase Notice contemplated by Section 4(c) hereof shall have the right at any
time prior to the close of business on the Business Day prior to the Fundamental Change Purchase
Date to withdraw such Fundamental Change Purchase Notice (in whole or in part) by delivery of a
written notice of withdrawal to the Paying Agent in accordance with Section 4(f) hereof.

     The Paying Agent shall promptly notify the Corporation of the receipt by it of any Fundamental
Change Purchase Notice or written notice of withdrawal thereof.

     On or before 10:00 a.m. (New York City time) on the Fundamental Change Purchase Date, the
Corporation shall deposit with the Paying Agent (or if the Corporation or an Affiliate of the
Corporation is acting as the Paying Agent, shall segregate and hold in trust) money sufficient to
pay the aggregate Fundamental Change Purchase Price of the Preferred Stock to be purchased pursuant
to this Section 4. Payment by the Paying Agent of the Fundamental Change Purchase Price for such
Preferred Stock shall be made promptly following the later of the Fundamental Change Purchase Date
or the time of book-entry transfer or delivery of such Preferred Stock. If the Paying Agent holds,
in accordance with the terms of this Certificate of Designation, money sufficient to pay the
Fundamental Change Purchase Price of such Preferred Stock on the Business Day following the
Fundamental Change Purchase Date, then, on and after such date, such Preferred Stock shall cease to
be outstanding and dividends (including Additional Dividends, if any) on such Preferred Stock shall
cease to accumulate, whether or not book-entry transfer of such Preferred Stock is made or such
Preferred Stock is delivered to the Paying Agent, and all other rights of the Holder shall
terminate (other than the right to receive the Fundamental Change Purchase Price upon delivery or
transfer of the Preferred Stock). Nothing herein shall preclude any withholding tax required by
law.

     The Corporation shall require each Paying Agent to agree in writing that the Paying Agent
shall hold in trust for the benefit of Holders all money held by the Paying Agent for the payment
of the Fundamental Change Purchase Price. If the Corporation or an Affiliate of the Corporation
acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a
separate trust fund.

     All questions as to the validity, eligibility (including time of receipt) and acceptance of
any Preferred Stock pursuant to a Fundamental Change shall be determined by the Corporation, whose
determination shall be final and binding.

     (e) Notice of Fundamental Change. The Corporation shall send notices (each, a “Corporation
Notice”) to the Holders (and to beneficial owners as required by applicable law) at their addresses
shown in the Security Register maintained by the Security Registrar, and delivered to the Paying
Agent on or before the 30th day after the occurrence of the Fundamental Change (“Corporation Notice
Date”). Each Corporation Notice shall include a form of Fundamental Change Purchase Notice to be
completed by a Holder and shall state:

	 	(i)	 	the applicable Fundamental Change Purchase Price, excluding accumulated and unpaid
dividends, Conversion Rate at the time of such notice (and any adjustments to the Conversion
Rate) and, to the extent known at the time of such notice, the amount of dividends (including
Additional Dividends, if any), if any, that will be payable with respect to the Preferred
Stock on the applicable Fundamental Change Purchase Date;
	 
	 	(ii)	 	the events causing the Fundamental Change and the date of the Fundamental Change;
	 
	 	(iii)	 	the Fundamental Change Purchase Date;
	 
	 	(iv)	 	the last date on which a Holder may exercise its purchase right;

10

 

	 	(v)	 	the name and address of the Paying Agent and the Conversion Agent;
	 
	 	(vi)	 	that the Preferred Stock must be surrendered to the Paying Agent to collect payment of
the Fundamental Change Purchase Price;
	 
	 	(vii)	 	that the Preferred Stock as to which a Fundamental Change Purchase Notice has been given
may be converted only if the applicable Fundamental Change Purchase Notice has been withdrawn
in accordance with the terms of this Certificate of Designation;
	 
	 	(viii)	 	that the Fundamental Change Purchase Price for any of the Preferred Stock as to which a
Fundamental Change Purchase Notice has been given and not withdrawn shall be paid by the
Paying Agent promptly following the later of the Fundamental Change Purchase Date or the time
of book-entry transfer or delivery of such Preferred Stock;
	 
	 	(ix)	 	the procedures the Holder must follow under this Section 4;
	 
	 	(x)	 	briefly, the conversion rights of the Preferred Stock;
	 
	 	(xi)	 	that, unless the Corporation defaults in making payment of such Fundamental Change
Purchase Price on the Preferred Stock covered by any Fundamental Change Purchase Notice,
dividends (including Additional Dividends, if any) will cease to accumulate on and after the
Fundamental Change Purchase Date;
	 
	 	(xii)	 	the CUSIP or ISIN number of the Preferred Stock; and
	 
	 	(xiii)	 	the procedures for withdrawing a Fundamental Change Purchase Notice.

     In connection with providing such Corporation Notice, the Corporation will issue a press
release and publish a notice containing the information in such Corporation Notice in a newspaper
of general circulation in The City of New York or publish such information on the Corporation’s
then existing Web site or through such other public medium as the Corporation may use at the time.

     At the Corporation’s request, made at least five Business Days prior to the date upon which
such notice is to be mailed, and at the Corporation’s expense, the Paying Agent shall give the
Corporation Notice in the Corporation’s name; provided, however, that, in all cases, the text of
the Corporation Notice shall be prepared by the Corporation.

     (f) Effect of Fundamental Change Purchase Notice. Upon receipt by the Corporation of the
Fundamental Change Purchase Notice specified in this Section 4, the Holder of the Preferred Stock
in respect of which such Fundamental Change Purchase Notice was given shall (unless such
Fundamental Change Purchase Notice is withdrawn as specified in this Section 4(f)) thereafter be
entitled to receive solely the Fundamental Change Purchase Price with respect to such Preferred
Stock. Such Fundamental Change Purchase Price shall be paid by the Paying Agent to such Holder
promptly following the later of (x) the Fundamental Change Purchase Date with respect to such
Preferred Stock (provided the conditions in this Section 4 have been satisfied) and (y) the time of
delivery or book-entry transfer of such Preferred Stock to the Paying Agent by the Holder thereof
in the manner required by this Section 4. Preferred Stock in respect of which a Fundamental Change
Purchase Notice has been given by the Holder thereof may not be converted for shares of Common
Stock on or after the date of the delivery of such Fundamental Change Purchase Notice unless such
Fundamental Change Purchase Notice has first been validly withdrawn as specified in this Section
4(f). Payment of the Fundamental Change Purchase Price for shares of Preferred Stock in registered,
certificated form (“Certificated Preferred Stock”) for which a Fundamental Change Purchase Notice
has been delivered and not withdrawn is conditioned upon delivery of such Certificated Preferred
Stock (together with necessary endorsements) to the Paying Agent at its office in Jackson,
Michigan, or any other office of the Paying Agent maintained for such purpose, at any time (whether
prior to, on or after the Fundamental Change Purchase Date) after the delivery of such Fundamental
Change Purchase Notice. Payment of the

11

 

Fundamental Change Purchase Price for such Certificated Preferred Stock will be made promptly
following the later of the Fundamental Change Purchase Date or the time of delivery of such
Certificated Preferred Stock.

     If the Paying Agent holds, in accordance with the terms of this Certificate of Designation,
money sufficient to pay the Fundamental Change Purchase Price of shares of Preferred Stock on the
Business Day following the Fundamental Change Purchase Date for such Preferred Stock, then, on and
after such date, dividends on such Preferred Stock will cease to accumulate, whether or not such
Preferred Stock is delivered to the Paying Agent, and all other rights of the Holder shall
terminate (other than the right to receive the Fundamental Change Purchase Price upon delivery of
the Preferred Stock).

     A Fundamental Change Purchase Notice may be withdrawn by means of a written notice of
withdrawal delivered to the office of the Paying Agent at any time prior to 5:00 p.m. New York City
time on the Business Day prior to the Fundamental Change Purchase Date to which it relates
specifying:

	 	(i)	 	if certificated, the certificate number of Preferred Stock in respect of which such notice
of withdrawal is being submitted, or, if not certificated, the written notice of withdrawal
must comply with appropriate Depository procedures;
	 
	 	(ii)	 	the number of shares of Preferred Stock with respect to which such notice of withdrawal
is being submitted; and
	 
	 	(iii)	 	the number of shares of Preferred Stock, if any, which remains subject to the original
Fundamental Change Purchase Notice and which have been or shall be delivered for purchase by
the Corporation.

     (g) Preferred Stock Purchased in Part. Any shares of Preferred Stock that are to be purchased
only in part shall be surrendered (in physical or book-entry form) at the office of the Paying
Agent (with, if the Corporation so requires, due endorsement by, or a written instrument of
transfer in form satisfactory to the Corporation duly executed by, the Holder thereof or such
Holder’s attorney duly authorized in writing) and the Corporation shall execute and the Transfer
Agent shall authenticate and deliver to the Holder of such Preferred Stock, without service charge,
new shares of Preferred Stock, as requested by such Holder in an amount equal to, and in exchange
for, the portion of the Liquidation Preference of the Preferred Stock so surrendered which is not
purchased.

     (h) Covenant to Comply with Securities Laws Upon Purchase of the Preferred Stock. In
connection with any offer to purchase Preferred Stock under this Section 4, the Corporation shall,
to the extent applicable: (i) comply with Rules 13e-4 and 14e-1 (and any successor provisions
thereto) under the Exchange Act, if applicable; (ii) file the related Schedule TO (or any successor
schedule, form or report) under the Exchange
Act, if applicable; and (iii) otherwise comply with all applicable federal and state securities
laws so as to permit the rights and obligations under this Section 4 hereof to be exercised in the
time and in the manner specified in this Section 4.

     (i) Repayment to the Corporation. The Paying Agent shall return to the Corporation any cash or
property that remains unclaimed as provided in the Preferred Stock, together with interest that the
Paying Agent has agreed to pay, if any, held by it for the payment of a Fundamental Change Purchase
Price; provided, however, that to the extent that the aggregate amount of cash or property
deposited by the Corporation pursuant to this Section 4 exceeds the aggregate Fundamental Change
Purchase Price of the Preferred Stock or portions thereof which the Corporation is obligated to
purchase as of the Fundamental Change Purchase Date, then promptly on and after the Business Day
following the Fundamental Change Purchase Date, the Paying Agent shall return any such excess to
the Corporation together with interest that the Paying Agent has agreed to pay, if any.

     (j) Officers’ Certificate. At least five Business Days before the Corporation Notice Date, the
Corporation shall deliver an Officers’ Certificate to the Paying Agent (provided, that, at the
Corporation’s option, the matters to be addressed in such Officers’ Certificate may be divided
among two such certificates) specifying:

	 	(i)	 	the manner of payment selected by the Corporation; and

12

 

	 	(ii)	 	whether the Corporation desires the Paying Agent to give the Corporation Notice required
by Section 4(e) hereof.

     5. Voting.

     (a) The shares of Preferred Stock shall have no voting rights except as set forth below or as
otherwise required by Michigan law from time to time:

	 	(i)	 	If and whenever at any time or times a Voting Rights Triggering Event occurs, then the
holders of shares of Preferred Stock, voting as a single class with any other preferred stock
or preference securities having similar voting rights that are
exercisable (the “Voting Rights
Class”), will be entitled at the next regular or special meeting of shareholders of the
Corporation to elect two additional directors of the Corporation, unless the Board of
Directors is comprised of fewer than six directors at such time, in which case the Voting
Rights Class shall be entitled to elect one additional director. Upon the election of any such
additional directors, the number of directors that comprise the Board of Directors shall be
increased by such number of additional directors.
	 
	 	(ii)	 	Such voting rights may be exercised at a special meeting of the holders of the shares of
the Voting Rights Class, called as hereinafter provided, or at any annual meeting of
shareholders held for the purpose of electing directors, and thereafter at each such annual
meeting until such time as all dividends in arrears on the shares of Preferred Stock shall
have been paid in full, at which time or times such voting rights and the term of the
directors elected pursuant to Section 5(a)(i) shall terminate.
	 
	 	(iii)	 	At any time when such voting rights shall have vested in holders of shares of the Voting
Rights Class, an Officer of the Corporation may call, and, upon written request of the record
holders of shares representing at least twenty-five percent (25%) of the voting power of the
shares then outstanding of the Voting Rights Class, addressed to the Secretary of the
Corporation, shall call a special meeting of the holders of shares of the Voting Rights Class.
Such meeting shall be held at the earliest practicable date upon the notice required for
annual meetings of shareholders at the place for holding annual meetings of shareholders of
the Corporation, or, if none, at a place designated by the Board of Directors. Notwithstanding
the provisions of this Section 5(a)(iii), no such special meeting shall be called during a
period within the 60 days immediately preceding the date fixed for the next annual meeting of
shareholders, in which such case the election of directors pursuant to Section 5(a)(i) shall
be held at such annual meeting of shareholders.
	 
	 	(iv)	 	At any meeting held for the purpose of electing directors at which the holders of the
Voting Rights Class shall have the right to elect directors as provided herein, the presence
in person or by proxy of the
holders of shares representing more than fifty percent (50%) in voting power of the then
outstanding shares of the Voting Rights Class shall be required and shall be sufficient to
constitute a quorum of such class for the election of directors by such class. The affirmative
vote of the holders of shares of Preferred Stock constituting a majority of the shares of
Preferred Stock present at such meeting, in person or by proxy shall be sufficient to elect
any such director.
	 
	 	(v)	 	Any director elected pursuant to the voting rights created under this Section 5(a) shall
hold office until the next annual meeting of shareholders (unless such term has previously
terminated pursuant to Section 5(a)(ii)) and any vacancy in respect of any such director shall
be filled only by vote of the remaining director so elected by holders of the Voting Rights
Class, or, if there be no such remaining director, by the holders of shares of the Voting
Rights Class at a special meeting called in accordance with the procedures set forth in this
Section 5, or, if no such special meeting is called, at the next annual meeting of
shareholders. Upon any termination of such voting rights, the term of office of all directors
elected pursuant to this Section 5 shall terminate.
	 
	 	(vi)	 	So long as any shares of Preferred Stock remain outstanding, unless a greater percentage
shall then be required by law, the Corporation shall not, without the affirmative vote or
consent of the holders of all

13

 

	 	 	 	of the outstanding Preferred Stock voting or consenting, as the case may be, separately as
one class, (i) create, authorize or issue any class or series of Senior Stock (or any
security convertible into Senior Stock) or (ii) amend the Articles of Incorporation so as
to affect adversely the specified rights, preferences, privileges or voting rights of
holders of shares of Preferred Stock.

	 	(vii)	 	In exercising the voting rights set forth in this Section 5(a), each share of Preferred
Stock shall be entitled to one vote.

     (b) The Corporation may authorize, increase the authorized amount of, or issue any class or
series of Parity Stock or Junior Stock, without the consent of the holders of Preferred Stock, and
in taking such actions the Corporation shall not be deemed to have affected adversely the rights,
preferences, privileges or voting rights of holders of shares of Preferred Stock.

     6. Liquidation Rights.

     (a) In the event of any liquidation, winding-up or dissolution of the Corporation, whether
voluntary of involuntary, each holder of shares of Preferred Stock shall be entitled to receive and
to be paid out of the assets of the Corporation available for distribution to its shareholders the
Liquidation Preference plus Accumulated Dividends and Additional Dividends thereon in preference to
the holders of, and before any payment or distribution is made on, any Junior Stock, including,
without limitation, on any Common Stock.

     (b) Neither the sale, conveyance, exchange or transfer (for cash, shares of stock,
securities or other consideration) of all or substantially all the assets or business of the
Corporation (other than in connection with the liquidation, winding-up or dissolution of its
business) nor the merger or consolidation of the Corporation into or with any other Person shall be
deemed to be a liquidation, winding-up or dissolution, voluntary or involuntary, for the purposes
of this Section 6.

     (c) After the payment to the holders of the shares of Preferred Stock of full preferential
amounts provided for in this Section 6, the holders of Preferred Stock as such shall have no right
or claim to any of the remaining assets of the Corporation.

     (d) In the event the assets of the Corporation available for distribution to the holders of
shares of Preferred Stock upon any liquidation, winding-up or dissolution of the Corporation,
whether voluntary or involuntary, shall be insufficient to pay in full all amounts to which such
holders are entitled pursuant to Section 6(a), no such distribution shall be made on account of any
shares of Parity Stock upon such liquidation, dissolution or winding-up unless proportionate
distributable amounts shall be paid on account of the shares of
Preferred Stock, ratably, in proportion to the full distributable amounts for which holders of
all Preferred Stock and of any Parity Stock are entitled upon such liquidation, winding-up or
dissolution.

     7. Conversion.

     (a) Conversion Rights. A Holder may convert Preferred Stock into cash and shares of Common
Stock during the periods and upon satisfaction of at least one of the conditions set forth below:

	 	(i)	 	in any calendar quarter (and only during such calendar quarter) if the Last Reported Sale
Price for Common Stock for at least 20 Trading Days during the period of 30 consecutive
Trading Days ending on the last Trading Day of the previous calendar quarter is greater than
or equal to 120% of the Conversion Price per share of Common Stock on such last Trading Day;
	 
	 	(ii)	 	during the five Business Days immediately following any ten consecutive Trading Day
period in which the Trading Price per Liquidation Preference of Preferred Stock (as determined
following a request by a Holder of Preferred Stock in accordance with the procedures described
herein) for each day of that period was less than 95% of the product of the sale price of
Common Stock and the then applicable Conversion Rate (the “Trading Exception”); provided,
however, that a Holder may not convert its

14

 

	 	 	 	Preferred Stock if the average closing sale price of Common Stock for such ten consecutive
Trading Day period is between the then current Conversion Price and 120% of the then
applicable Conversion Price; in connection with any conversion upon satisfaction of such
Trading Price condition, the Conversion Agent shall have no obligation to determine the
Trading Price unless the Corporation has requested such determination; and the Corporation
shall have no obligation to make such request unless the Holder provides reasonable
evidence that the Trading Price would be less than 95% of the product of the sale price of
Common Stock and the then applicable Conversion Rate; at which time, the Corporation shall
instruct the Conversion Agent to determine the Trading Price beginning on the next Trading
Day and on each successive Trading Day until the Trading Price is greater than or equal to
95% of the product of the sale price of Common Stock and the then applicable Conversion
Rate;
	 
	 	(iii)	 	the Corporation becomes a party to a consolidation, merger or binding share exchange
pursuant to which the Common Stock would be converted into cash or property (other than
securities), in which case a Holder may surrender Preferred Stock for conversion at any time
from and after the date which is 15 days prior to the anticipated effective date for the
transaction until 15 days after the actual effective date (the “Effective Date”) of such
transaction; or
	 
	 	(iv)	 	the Corporation elects to (i) distribute to all holders of Common Stock assets, debt
securities or rights to purchase securities of the Corporation, which distribution has a per
share value as determined by the Board of Directors exceeding 15% of the Last Reported Sale
Price of a share of Common Stock on the Trading Day immediately preceding the declaration date
for such distribution, or (ii) distribute to all holders of Common Stock rights entitling them
to purchase, for a period expiring within 60 days after the date of such distribution, shares
of Common Stock at less than the Last Reported Sale Price of Common Stock on the Trading Day
immediately preceding the declaration date of the distribution. In the case of the foregoing
clauses (i) and (ii), the Corporation must notify the Holders at least 20 Business Days
immediately prior to the ex-dividend date for such distribution. Once the Corporation has
given such notice, Holders may surrender their Preferred Stock for conversion at any time
thereafter until the earlier of the close of business on the Business Day immediately prior to
the ex-dividend date or the Corporation’s announcement that such distribution will not take
place; provided, however, that a Holder may not exercise this right to convert if the Holder
may participate in the distribution without conversion. As used herein, the term “ex dividend
date,” when used with respect to any issuance or distribution, shall mean the first date on
which the Common Stock trades regular way on such exchange or in such market without the right
to receive such issuance or distribution.

     The initial Conversion Rate is 5.0541 shares of Common Stock per share of Preferred Stock,
subject to adjustment in certain events as described herein. The Corporation shall deliver cash or
a check in lieu of any
fractional share of Common Stock. A Holder may convert fewer than all of its Preferred Stock
so long as the Preferred Stock converted is an integral multiple of the Liquidation Preference.

     Holders of Preferred Stock at the close of business on a Dividend Record Date will receive
payment of dividends, payable on the corresponding Dividend Payment Date notwithstanding the
conversion of such Preferred Stock at any time after the close of business on such Dividend Record
Date. Preferred Stock surrendered for conversion by a Holder during the period from the close of
business on any Dividend Record Date to the opening of business on the immediately following
Dividend Payment Date must be accompanied by payment of an amount equal to the dividend that the
Holder is to receive on such Preferred Stock; provided, however, that no such payment need be made
if (1) the Corporation has specified a Mandatory Conversion Date that is after a Dividend Record
Date and on or prior to the immediately following Dividend Payment Date or (2) any accumulated and
unpaid dividends exist at the time of conversion with respect to such shares of Preferred Stock to
the extent of such accumulated and unpaid dividends.

     To convert Preferred Stock a Holder must (i) complete and manually sign the irrevocable
conversion notice in the form attached hereto as Exhibit B (a “Conversion Notice”) (or complete and
manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent at its
office in Jackson, Michigan or any other offices

15

 

of the Conversion Agent maintained by the Conversion Agent for such purpose, (ii) surrender the
shares of Preferred Stock to the Conversion Agent, (iii) furnish appropriate endorsements and
transfer documents if required by the Conversion Agent or the Corporation and (iv) pay any transfer
or similar tax, if required.

     (b) Conversion Procedures. To convert Preferred Stock, a Holder must satisfy the requirements
in this Section 7 and in the Preferred Stock. The date on which the Holder satisfies all those
requirements is the conversion date (the “Conversion Date”). Subject to the procedures set forth in
Section 7(f) hereof, as soon as practicable, but in no event later than the fifth Business Day
following the Conversion Date, the Corporation shall deliver the Conversion Value in cash and
deliver the Common Stock by either of the following methods: (i) update the global security
representing the shares of Common Stock to record the Holder’s interest in the Common Stock, or
(ii) deliver to the Holder, through the Conversion Agent, a certificate for the number of full
shares representing Net Shares, if any, together with, in either case, cash or a check in lieu of
any fractional share determined pursuant to Section 7(c) hereof. The Person in whose name the
certificate is registered shall be treated as a shareholder of record on and after the Conversion
Date; provided, however, that no surrender of Preferred Stock on any date when the stock transfer
books of the Corporation shall be closed shall be effective to constitute the Person or Persons
entitled to receive the shares of Common Stock upon such conversion as the record holder or holders
of such shares of Common Stock on such date, but such surrender shall be effective to constitute
the Person or Persons entitled to receive such shares of Common Stock as the record holder or
holders thereof for all purposes at the close of business on the next succeeding day on which such
stock transfer books are open; such conversion shall be at the Conversion Rate in effect on the
date that such shares of Preferred Stock shall have been surrendered for conversion, as if the
stock transfer books of the Corporation had not been closed. Upon conversion of Preferred Stock,
such Person shall no longer be a Holder of such Preferred Stock.

     No payment or adjustment shall be made for dividends on or other distributions with respect to
any Common Stock except as provided in Section 7(f) hereof or as otherwise provided in this
Certificate of Designation.

     On conversion of Preferred Stock, delivery of the Principal Return, the Net Shares and the
cash or check payment, if any, in lieu of fractional shares will be deemed to satisfy the
Corporation’s obligation to pay the Liquidation Preference of the converted Preferred Stock,
including Accumulated Dividends, if any. Accumulated Dividends with respect to the converted
Preferred Stock will be deemed canceled, extinguished or forfeited, rather than paid in full to the
Holder thereof.

     Upon surrender of Preferred Stock that is converted in part, the Corporation shall execute,
and the Transfer Agent shall authenticate and deliver to the Holder, new shares of Preferred Stock
in a number equal to the unconverted portion of the shares of Preferred Stock surrendered.

     If the last day on which Preferred Stock may be converted is a legal holiday in a place where
a Conversion Agent is located, the Preferred Stock may be surrendered to that Conversion Agent on
the next succeeding day that it is not a legal holiday.

     (c) Cash or Check Payments in Lieu of Fractional Shares. The Corporation shall not issue a
fractional share of Common Stock upon conversion of Preferred Stock. Instead the Corporation shall
deliver cash (or Corporation’s check) for the current market value of the fractional share. The
current market value of a fractional share shall be determined to the nearest 1/10,000th of a share
by multiplying the Last Reported Sale Price of a full share of Common Stock on the Trading Day
immediately preceding the Conversion Date by the fractional amount and rounding the product to the
nearest whole cent.

     (d) Taxes on Conversion. If a Holder converts Preferred Stock, the Corporation shall pay any
documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon
the conversion. However, the Holder shall pay any such tax which is due because the Holder requests
the shares to be issued in a name other than the Holder’s name. The Conversion Agent may refuse to
deliver the certificates representing the Common Stock being issued in a name other than the
Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax which shall be
due because the shares are to be issued in a name other than the Holder’s name. Nothing herein
shall preclude any withholding tax required by law.

16

 

     (e) Covenants of the Corporation. The Corporation shall, prior to issuance of any Preferred
Stock hereunder, and from time to time as may be necessary, reserve out of its authorized but
unissued Common Stock a sufficient number of shares of Common Stock to permit the conversion of the
Preferred Stock.

     All shares of Common Stock delivered upon conversion of the Preferred Stock shall be newly
issued shares or treasury shares, shall be duly and validly issued and fully paid and nonassessable
and shall be free from preemptive rights and free of any lien or adverse claim.

     The Corporation shall endeavor promptly to comply with all federal and state securities laws
regulating the order and delivery of shares of Common Stock upon the conversion of Preferred Stock,
if any, and shall cause to have listed or quoted all such shares of Common Stock on each United
States national securities exchange or over-the-counter or other domestic market on which the
Common Stock is then listed or quoted.

     (f) Adjustments to Conversion Rate. The Conversion Rate shall be adjusted from time to time,
without duplication, as follows:

	 	(i)	 	In case the Corporation shall: (A) pay a dividend, or make a distribution, exclusively in
shares of its capital stock, on the Common Stock; (B) subdivide its outstanding Common Stock
into a greater number of shares; (C) combine its outstanding Common Stock into a smaller
number of shares; or (D) reclassify its Common Stock, the Conversion Rate in effect
immediately prior to the record date or effective date, as the case may be, for the
adjustment pursuant to this Section 7(f) as described below, shall be adjusted so that the
Holder of any Preferred Stock thereafter surrendered for conversion shall be entitled to
receive the cash and number of shares of Common Stock of the Corporation which such Holder
would have owned or have been entitled to receive after the happening of any of the events
described above had such Preferred Stock been converted immediately prior to such record date
or effective date, as the case may be. An adjustment made pursuant to this Section 7(f) shall
become effective immediately after the applicable record date in the case of a dividend or
distribution and shall become effective immediately after the applicable effective date in
the case of subdivision, combination or reclassification of the Corporation’s Common Stock.
If any dividend or distribution of the type described in clause (A) above is not so paid or
made, the Conversion Rate shall again be adjusted to the Conversion Rate which would then be
in effect if such dividend or distribution had not been declared.
	 
	 	(ii)	 	In case the Corporation shall issue rights or warrants to all holders of the Common
Stock entitling them (for a period expiring within 60 days after the date of issuance of such
rights or warrants) to subscribe for or purchase Common Stock at a price per share less than
the Market Price per share of Common Stock on the record date fixed for determination of
shareholders entitled to receive such rights
or warrants, the Conversion Rate in effect immediately after such record date shall be
adjusted so that the same shall equal the Conversion Rate determined by multiplying the
Conversion Rate in effect immediately after such record date by a fraction of which (A) the
numerator shall be the number of shares of Common Stock outstanding on such record date plus
the number of additional shares of Common Stock offered for subscription or purchase, and (B)
the denominator shall be the number of shares of Common Stock outstanding on such record date
plus the number of shares which the aggregate offering price of the total number of shares so
offered would purchase at the Market Price per share of Common Stock on the earlier of such
record date or the Trading Day immediately preceding the ex-dividend date for such issuance
of rights or warrants. Such adjustment shall be made successively whenever any such rights or
warrants are issued, and shall become effective immediately after the opening of business on
the day following the record date for the determination of shareholders entitled to receive
such rights or warrants. To the extent that shares of Common Stock are not delivered after
the expiration of such rights or warrants, the Conversion Rate shall be readjusted to the
Conversion Rate which would then be in effect had the adjustments made upon the issuance of
such rights or warrants been made on the basis of delivery of only the number of shares of
Common Stock actually delivered. If such rights or warrants are not so issued, the Conversion
Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such
record date for

17

 

	 	 	 	the determination of shareholders entitled to receive such rights or warrants had not been
fixed. In determining whether any rights or warrants entitle the holders to subscribe for or
purchase shares of Common Stock at less than such Market Price, and in determining the
aggregate offering price of such shares of Common Stock, there shall be taken into account any
consideration received by the Corporation for such rights or warrants, the value of such
consideration, if other than cash, to be determined by the Board of Directors.

	 	(iii)	 	In case the Corporation shall, by dividend or otherwise, distribute to all holders of Common
Stock any assets, debt securities or rights or warrants to purchase any of its securities
(excluding (a) any dividend, distribution or issuance covered by those referred to in Section
7(f)(i) or Section 7(f)(ii) hereof and (b) any dividend or distribution paid exclusively in cash)
(any of the foregoing hereinafter in this Section 7(f)(iii) called the “Distributed Assets or
Securities”) in an aggregate amount per share of Common Stock that, combined together with the
aggregate amount of any other such distributions to all holders of its Common Stock made within the
12 months preceding the date of payment of such distribution, and in respect of which no adjustment
pursuant to this Section 7(f)(iii) has been made, exceeds 15% of the Market Price on the Trading
Day immediately preceding the declaration of such distribution, then the Conversion Rate shall be
adjusted so that the same shall equal the Conversion Rate determined by multiplying the Conversion
Rate in effect immediately prior to the close of business on the record date mentioned below by a
fraction of which (A) the numerator shall be the Market Price per share of the Common Stock on the
earlier of such record date or the Trading Day immediately preceding the ex-dividend date for such
dividend or distribution, and (B) the denominator shall be (1) the Market Price per share of the
Common Stock on the earlier of such record date or the Trading Day immediately preceding the
ex-dividend date for such dividend or distribution less (2) the Fair Market Value on the earlier of
such record date or the Trading Day immediately preceding the ex-dividend date for such dividend or
distribution (as determined by the Board of Directors, whose determination shall be conclusive, and
described in a certificate filed with the Paying Agent) of the Distributed Assets or Securities so
distributed applicable to one share of Common Stock. Such adjustment shall become effective
immediately after the record date for the determination of shareholders entitled to receive such
distribution; provided, however, that, if (a) the Fair Market Value of the portion of the
Distributed Assets or Securities so distributed applicable to one share of Common Stock is equal to
or greater than the Market Price of the Common Stock on the record date for the determination of
shareholders entitled to receive such distribution or (b) the Market Price of the Common Stock on
the record date for the determination of shareholders entitled to receive such distribution is
greater than the Fair Market Value per share of such Distributed Assets or Securities by less than
$1.00, then, in lieu of the foregoing adjustment, adequate provision shall be made so that each
Holder shall have the right to receive upon conversion, in addition to the cash and shares of
Common Stock, the kind and amount of assets, debt securities, or rights or warrants comprising the
Distributed Assets or Securities the Holder would have received had such Holder converted such
Preferred Stock immediately prior to the record date for the
determination of shareholders entitled to receive such distribution. In the event that such
distribution is not so paid or made, the applicable
Conversion Rate shall again be adjusted to the Conversion Rate which would then be in effect if
such distribution had not been declared.
	 
	 	(iv)	 	In case the Corporation shall declare a cash dividend or cash distribution to all or
substantially all of the holders of Common Stock, the Conversion Rate shall be increased so that
the applicable Conversion Rate shall equal the price determined by multiplying the Conversion Rate
in effect immediately prior to the record date for such dividend or distribution by a fraction,

(A) the numerator of which shall be the average of the Last Reported Sale Price of Common
Stock for the five consecutive Trading Days ending on the Trading Day immediately preceding the
record date for such dividend or distribution (the “Pre-Dividend Sale Price”), and

(B) the denominator of which shall be the Pre-Dividend Sale Price, minus the full amount of
such cash dividend or cash distribution applicable to one share of Common Stock (the “Dividend

18

 

Adjustment Amount”), with such adjustment to become effective immediately after the record date
for such dividend or distribution; provided that if the denominator of the foregoing fraction
is less than $1.00 (including a negative amount), then in lieu of the foregoing adjustment,
adequate provision shall be made so that each Holder shall have the right to receive upon
conversion, in addition to the cash and Common Stock issuable upon such conversion, the amount
of cash such Holder would have received had such Holder converted its Preferred Stock solely
into Common Stock at the then applicable Conversion Rate immediately prior to the record date
for such cash dividend or cash distribution. If such cash dividend or cash distribution is not
so paid or made, the applicable Conversion Rate shall again be adjusted to be the Conversion
Rate that would then be in effect if such dividend or distribution had not been declared.

	 	(v)	 	In the case the Corporation shall make (a) any distributions, by dividend or otherwise, during
any quarterly fiscal periods consisting exclusively of cash to all holders of outstanding shares of
Common Stock in an aggregate amount that, together with (b) other all-cash or all-check
distributions made to all holders of outstanding shares of Common Stock during such quarterly
fiscal period, and (c) any cash and the Fair Market Value, as of the expiration of any tender or
exchange offer (other than consideration payable in respect of any odd-lot tender offer) of
consideration payable in respect of any tender or exchange offer by the Corporation or any of the
Corporation’s Subsidiaries for all or any portion of shares of Common Stock concluded during such
quarterly fiscal period, exceed the product of $0 multiplied by the number of shares of Common
Stock outstanding on the record date for such distribution, then, and in each such case, the
Conversion Rate shall be increased in accordance with the provisions of clause (iv) above.
	 
	 	(vi)	 	If a Holder elects to convert Preferred Stock in connection with a corporate transaction that
occurs on or prior to December 5, 2008 that constitutes a Fundamental Change (other than as
described in clause (iv) of the definition of Fundamental Change) and 10% or more of the Fair
Market Value of the consideration for the Common Stock (as determined by the Board of Directors,
whose determination shall be conclusive evidence of such Fair Market Value) in the corporate
transaction consists of (A) cash, (B) other property or (C) securities that are not traded or
scheduled to be traded immediately following such transaction on a U.S. national securities
exchange or the Nasdaq National Market, then the Conversion Rate for the Preferred Stock
surrendered for conversion by such Holder shall be adjusted so that such Holder will be entitled to
receive cash and shares of Common Stock equal to the sum of (1) the Conversion Value and (2) the
number of additional shares of Common Stock (the “Additional Shares”) determined in the manner set
forth below, subject in each case to the Corporation’s payment elections as described in Section 7
hereof. For the avoidance of doubt, the adjustment provided for in this Section 7(f)(vi) shall only
be made with respect to the Preferred Stock being converted in connection with such Fundamental
Change and shall not be effective as to any Preferred Stock not so converted.

The number of Additional Shares will be determined by reference to the table below, based on
the date on which such corporate transaction becomes effective (the “Effective Date”) and the
Share Price; provided that if the Share Price is between two Share Price amounts in the table
below or the Effective Date is between two Effective Dates in the table, the number of
Additional Shares will be determined by a straight-line interpolation between the number of
Additional Shares set forth for the higher and lower Share Price amounts and the two dates, as
applicable, based on a 365-day year.

The Share Prices set forth in the first row of the table below (i.e., column headers) will be
adjusted as of any date on which the applicable Conversion Rate of the Preferred Stock is
adjusted pursuant to this Section 7(f). The adjusted Share Prices will equal the Share Prices
applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of
which is the Conversion Rate immediately prior to the adjustment giving rise to the Share Price
adjustment and the denominator of which is the Conversion Rate as so adjusted.

The following table sets forth the hypothetical Share Price and number of Additional Shares to be
received per Liquidation Preference of the Preferred Stock:

The Share Prices and Additional Share amounts set forth above are based upon an initial
Conversion Rate per share of 5.0541 per Liquidation Preference of the Preferred Stock.

If the Share Price is equal to or in excess of $50.00 per share (subject to adjustment), no
Additional Shares will be issued upon conversion.

If the Share Price is less than $7.61 per share (subject to adjustment), no Additional Shares
will be issued upon conversion.

Notwithstanding the foregoing, any adjustment to the applicable Conversion Rate relating to the
issuance of Additional Shares as described in this Section 7(f)(vi) will not exceed the Maximum
Conversion Rate.

	 	(vii)	 	Notwithstanding the foregoing, in the case of a Public Acquirer Change of Control, the
Corporation may, in lieu of increasing the applicable Conversion Rate by Additional Shares as
described in Section 7(f)(vii) hereof, elect to adjust the applicable Conversion Rate and the
related conversion obligation such that upon conversion the Issuer will deliver cash and a number
of shares of Public Acquirer Common Stock such that by multiplying the Conversion Rate in effect
immediately before the Public Acquirer Change of Control shall be adjusted by a fraction:

(A) the numerator of which will be the average of the Last Reported Sale Price of the Common
Stock for the five consecutive trading days prior to but excluding the effective date of such
Public Acquirer Change of Control; and

(B) the denominator of which will be the average of the Last Reported Sale Price of the Public
Acquirer Common Stock for the five consecutive trading days commencing on the Trading Day next
succeeding the effective date of such Public Acquirer Change of Control.

A “Public Acquirer Change of Control” means any event described in Section 7(f)(vi) hereof that
would otherwise obligate the Corporation to increase the Conversion Rate as described in
Section 7(f)(vi) hereof and the acquirer (or any entity of which the acquirer is a directly or
indirectly wholly-owned Subsidiary and such entity provides a guarantee to the Preferred Stock)
has a class of common stock traded on a U.S. national securities exchange or quoted on the
Nasdaq National Market or which will be so traded or quoted when issued or exchanged in
connection with such event (the ‘‘Public Acquirer Common Stock’’).

After the adjustment of the applicable Conversion Rate in connection with a Public Acquirer
Change of Control, the applicable Conversion Rate will be subject to further similar
adjustments in the event that any of the events described in this Section 7(f) occur
thereafter.

The Corporation is required to notify Holders of its election in writing of such transaction,
which notice shall be made five Business Days prior to the effective date of such Public
Acquirer Change of Control. In addition, the Holder can also, subject to certain conditions,
require the Corporation to repurchase all or a portion of its Preferred Stock as described
under Section 4.

20

 

	 	(viii)	 	With respect to Section 7(f)(iii) hereof, in the event that the Corporation makes any
distribution to all holders of Common Stock consisting of Equity Interests in a Subsidiary or
other business unit of the Corporation, the Conversion Rate shall be adjusted so that the
same shall equal the Conversion Rate determined by multiplying the Conversion Rate in effect
immediately prior to the close of business on the record date fixed for the determination of
holders of Common Stock entitled to receive such distribution by a fraction of which (A) the
numerator shall be (x) the Spin-off Market Price per share of the Common Stock on such record
date plus (y) the Spin-off Market Price per Equity Interest of the Subsidiary or other
business unit of the Corporation on such record date and (B) the denominator shall be the
Spin-off Market Price per share of the Common Stock on such record date, such adjustment to
become effective 10 Trading Days after the effective date of such distribution of Equity
Interests in a Subsidiary or other business unit of the Corporation.
	 
	 	(ix)	 	Upon conversion of the Preferred Stock, the Holders shall receive, in addition to the
cash and Common Stock issuable upon such conversion, the rights issued under any future
shareholder rights plan the Corporation implements (notwithstanding the occurrence of an
event causing such rights to separate from the Common Stock at or prior to the time of
conversion) unless, prior to conversion, the rights have expired, terminated or been redeemed
or exchanged in accordance with such rights plan. If, and only if, the Holders of Preferred
Stock receive rights under such shareholder rights plans as described in the preceding
sentence upon conversion of their Preferred Stock, then no other adjustment pursuant to this
Section 7(f) shall be made in connection with such shareholder rights plans.
	 
	 	(x)	 	For purposes of this Section 7(f), the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Corporation but shall
include shares issuable in respect of scrip certificates issued in lieu of fractions of
shares of Common Stock. The Corporation shall not pay any dividend or make any distribution
on shares of Common Stock held in the treasury of the Corporation.
	 
	 	(xi)	 	Notwithstanding the foregoing, in no event shall the Conversion Rate exceed the maximum
conversion rate specified under this Section 7(f)(xi) (the “Maximum Conversion Rate”) as a
result of an adjustment pursuant to Sections 7(f)(iii), 7(f)(iv) or 7(f)(vi) hereof. The
Maximum Conversion Rate shall initially be 6.5703 and shall be appropriately adjusted from
time to time for any stock dividends on or subdivisions or combinations of the Common Stock.
The Maximum Conversion Rate shall not apply to any adjustments made pursuant to any of the
events in Section 7(f)(i) or Section 7(f)(ii) hereof.

     (g) Calculation Methodology. No adjustment in the Conversion Price need be made unless the
adjustment would require an increase or decrease of at least 1% in the Conversion Price then in
effect, provided that any adjustment that would otherwise be required to be made shall be carried
forward and taken
into account in any subsequent adjustment. Except as stated in this Section 7, the Conversion
Rate will not be adjusted for the issuance of Common Stock or any securities convertible into or
exchangeable for Common Stock or carrying the right to purchase any of the foregoing. Any
adjustments that are made shall be carried forward and taken into account in any subsequent
adjustment. All calculations under Section 4 and Section 7(f) hereof and this Section 7(g) shall be
made to the nearest cent or to the nearest 1/10,000th of a share, as the case may be.

     (h) When No Adjustment Required. No adjustment to the Conversion Rate need be made:

	 	(i)	 	upon the issuance of any shares of Common Stock pursuant to any present or future plan
providing for the reinvestment of dividends or interest payable on securities of the
Corporation and the investment of additional optional amounts in shares of Common Stock under
any plan;
	 
	 	(ii)	 	upon the issuance of any shares of Common Stock or options or rights to purchase those
shares pursuant to any present or future employee, director or consultant benefit plan or
program of or assumed by the Corporation or any of its Subsidiaries;

21

 

	 	(iii)	 	upon the issuance of any shares of Common Stock pursuant to any option, warrant, right,
or exercisable, exchangeable or convertible security not described in clause (ii) above and
outstanding as of the date of this Certificate of Designation;
	 
	 	(iv)	 	for a change in the par value or no par value of the Common Stock;
	 
	 	(v)	 	for accumulated and unpaid dividends (including Additional Dividends, if any); or
	 
	 	(vi)	 	if Holders are to participate in a merger or consolidation on a basis and with notice
that the Board of Directors determines to be fair and appropriate in light of the basis and
notice on which holders of Common Stock participate in the transaction; provided that the
basis on which the Holders are to participate in the transaction shall not be deemed to be
fair if it would require the conversion of securities at any time prior to the expiration of
the conversion period specified for such securities.

     To the extent the Preferred Stock becomes convertible into cash, assets or property (other
than capital stock of the Corporation or securities to which Section 7(l) hereof applies), no
adjustment shall be made thereafter as to the cash, assets or property. Interest shall not
accumulate on such cash.

     (i) Notice of Adjustment. Whenever the Conversion Rate is adjusted, the Corporation shall
promptly mail to Holders a notice of the adjustment. The Corporation shall file with the
Conversion Agent such notice. The certificate shall, absent manifest error, be conclusive evidence
that the adjustment is correct. No Conversion Agent shall be under any duty or responsibility with
respect to any such certificate except to exhibit the same to any Holder desiring inspection
thereof.

     (j) Voluntary Increase. The Corporation may make such increases in the Conversion Rate, in
addition to those required by Section 7(f) hereof, as the Board of Directors considers to be
advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase
Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or
from any event treated as such for income tax purposes. To the extent permitted by applicable law,
the Corporation may from time to time increase the Conversion Rate by any amount, temporarily or
otherwise, for any period of at least 20 days if the increase is irrevocable during the period and
the Board of Directors shall have made a determination that such increase would be in the best
interests of the Corporation, which determination shall be conclusive. Whenever the Conversion
Rate is so increased, the Corporation shall mail to Holders and file with the Conversion Agent a
notice of such increase. The Conversion Agent shall not be under any duty or responsibility with
respect to any such notice except to exhibit the same to any holder desiring inspection thereof.
The Corporation shall mail the notice at least 15 days before the date the increased Conversion
Rate takes effect. The notice shall state the increased Conversion Rate and the period it shall be
in effect.

     (k) Notice to Holders Prior to Certain Actions. In case:

	 	(i)	 	the Corporation shall declare a dividend (or any other distribution) on its Common Stock
that would require an adjustment in the Conversion Rate pursuant to Section 7(f) hereof;
	 
	 	(ii)	 	the Corporation shall authorize the granting to all or substantially all the holders of
its Common Stock of rights or warrants to subscribe for or purchase any share of any class or
any other rights or warrants;
	 
	 	(iii)	 	of any reclassification or reorganization of the Common Stock of the Corporation (other
than a subdivision or combination of its outstanding Common Stock, or a change in par value,
or from par value to no par value, or from no par value to par value), or of any
consolidation or merger to which the Corporation is a party and for which approval of any
shareholders of the Corporation is required, or of the sale or transfer of all or
substantially all of the assets of the Corporation; or
	 
	 	(iv)	 	of the voluntary or involuntary dissolution, liquidation or winding-up of the
Corporation, the Corporation shall cause to be filed with the Conversion Agent and to be
mailed to each Holder at its address

22

 

	 	 	 	appearing on the Security Register, as promptly as possible but in any event at least 15
days prior to the applicable date hereinafter specified, a notice stating (x) the date on
which a record is to be taken for the purpose of such dividend, distribution or rights or
warrants, or, if a record is not to be taken, the date as of which the holders of Common
Stock of record to be entitled to such dividend, distribution, or rights or warrants are
to be determined or (y) the date on which such reclassification, reorganization,
consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected
to become effective or occur, and the date as of which it is expected that holders of
Common Stock of record shall be entitled to exchange their Common Stock for securities or
other property deliverable upon such reclassification, reorganization, consolidation,
merger, sale, transfer, dissolution, liquidation or winding-up. Failure to give such
notice, or any defect therein, shall not affect the legality or validity of such
dividend, distribution, reclassification, reorganization, consolidation, merger, sale,
transfer, dissolution, liquidation or winding-up.

     (l) Effect of Reclassification, Consolidation, Merger, Binding Share Exchange or Sale. If
any of the following events occur, namely: (i) any reclassification or change of outstanding shares
of Common Stock (other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination); (ii) any consolidation,
merger, combination or binding share exchange of the Corporation with another Person as a result of
which holders of Common Stock shall be entitled to receive stock, securities or other property or
assets (including cash) with respect to or in exchange for such Common Stock; or (iii) any sale or
conveyance of the properties and assets of the Corporation as, or substantially as, an entirety to
any other Person as a result of which holders of Common Stock shall be entitled to receive stock,
securities or other property or assets (including cash) with respect to or in exchange for such
Common Stock, then the Corporation or the successor or purchasing Person, as the case may be, shall
cause an amendment to this Certificate of Designation to be executed and filed in accordance with
Michigan law, providing that each share of Preferred Stock shall be convertible into the kind and
amount of shares of stock and other securities or property or assets (including cash) receivable
upon such reclassification, change, consolidation, merger, combination, binding share exchange,
sale or conveyance by a holder of a number of shares of Common Stock issuable upon conversion of
such Preferred Stock immediately prior to such reclassification, change, consolidation, merger,
combination, binding share exchange, sale or conveyance. Such amended Certificate of Designation
shall provide for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Section 7(l).

     The Corporation shall cause notice of the execution of such amended Certificate of Designation
to be mailed to each Holder, at its address appearing on the Security Register, within 20 days
after filing thereof. Failure to deliver such notice shall not affect the legality or validity of
such supplemental indenture.

     The above provisions of this Section 7(l) shall similarly apply to successive
reclassifications, changes, consolidations, mergers, combinations, binding share exchanges, sales
and conveyances.

     If this Section 7(l) applies to any event or occurrence, Section 7(f) hereof shall not apply.

     (m) Conversion Value of Preferred Stock Tendered.

	 	(i)	 	Subject to certain exceptions described in Sections 7(a)(ii), 7(a)(iii) and 7(a)(iv),
Holders tendering the Preferred Stock for conversion shall be entitled to receive, upon
conversion of such Preferred Stock, per the Liquidation Preference, cash and shares of Common
Stock, the value of which (the “Conversion Value”) shall be equal to the product of:

(A) the
then applicable Conversion Rate; and

(B) the average of the Common Stock prices for the ten consecutive Trading Days
(appropriately adjusted to take into account the occurrence during such period of
stock splits, stock dividends and similar events) beginning on the second Trading Day
immediately following the day the Preferred Stock is tendered for conversion (the “Ten
Day Average Closing Stock Price”).

23

 

	 	(ii)	 	Subject to certain exceptions described below and under Sections 7(a)(ii), 7(a)(iii) and
7(a)(iv), the Corporation shall deliver the Conversion Value to converting Holders as
follows:

(A) an amount in cash (the “Principal Return”) equal to the lesser of (1) the
Conversion Value of the Preferred Stock to be converted and (2) the aggregate
Liquidation Preference per share of Preferred Stock to be converted;

(B) if the aggregate Conversion Value of the Preferred Stock to be converted is
greater than the Principal Return, an amount in whole shares (the “Net Shares”),
determined as set forth below, equal to such aggregate Conversion Value less the
Principal Return (the “Net Share Amount”); and

(C) an amount paid in cash, determined as set forth below, in lieu of any fractional
shares of Common Stock.

     The number of Net Shares to be paid shall be determined by dividing the Net Share Amount by
the Ten Day Average Closing Stock Price. Holders of Preferred Stock will not receive fractional
shares upon conversion of Preferred Stock. In lieu of fractional shares, Holders will receive cash
for the value of the fractional shares, which cash payment shall be based on the Ten Day Average
Closing Stock Price.

     The Conversion Value, Principal Return, number of Net Shares and Net Share Amount shall be
determined by the Corporation at the end of the ten consecutive Trading Day period beginning on the
second Trading Day immediately following the day the Preferred Stock are tendered for conversion
(the “Determination Date”).

     The Corporation shall pay the Principal Return and cash for fractional shares and deliver the
Net Shares, if any, as promptly as practicable after the Determination Date, but in no event later
than five Business Days thereafter. Except as provided in Section 7, delivery of the Principal
Return, Net Shares and cash in lieu of fractional shares shall be deemed to satisfy the
Corporation’s obligation to pay the Liquidation Preference, including Additional Dividends, if any.
Any accumulated and unpaid dividends, including Additional Dividends, shall be deemed canceled,
extinguished or forfeited rather than paid in full.

     (n) Responsibility of Conversion Agent. The Conversion Agent shall not at any time be under
any duty or responsibility to any Holder to either calculate the Conversion Rate or determine
whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to
the nature or extent or calculation of any such adjustment when made, or with respect to the method
employed, or herein or in any amended Certificate of Designation provided to be employed, in making
the same and shall be protected in relying upon
an Officers’ Certificate with respect to the same. The Conversion Agent shall not be accountable
with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of
any securities or property, which may at any time be issued or delivered upon the conversion of any
Preferred Stock and the Conversion Agent makes no representations with respect thereto. The
Conversion Agent shall not be responsible for any failure of the Corporation to issue, transfer or
deliver any shares of Common Stock or stock certificates or other securities or property or cash
upon the surrender of any Preferred Stock for the purpose of conversion or to comply with any of
the duties, responsibilities or covenants of the Corporation contained in this Section 7(n).
Without limiting the generality of the foregoing, the Conversion Agent shall not be under any
responsibility to determine the correctness of any provisions contained in any amended Certificate
of Designation entered into pursuant to this Section 7 relating either to the kind or amount of
shares of stock or securities or property (including cash) receivable by Holders upon the
conversion of their Preferred Stock after any event referred to in this Section 7 or to any
adjustment to be made with respect thereto, but may accept as conclusive evidence of the
correctness of any such provisions, and shall be protected in relying upon, the Officers’
Certificate (which the Corporation shall be obligated to file with the Conversion Agent prior to
the execution of any such amended Certificate of Designation) with respect thereto.

     (o) Simultaneous Adjustments. In the event that Section 7(f) hereof requires adjustments to
the Conversion Rate under more than one of Section 7(f)(i), Section 7(f)(ii), Section 7(f)(iii) or
Section 7(f)(iv) hereof, and the Dividend Record Dates for the distributions giving rise to such
adjustments shall occur on the same date, then such adjustments shall be made by applying, first,
the provisions of Section 7(f)(iii) hereof, second, the

24

 

provisions of Section 7(f)(i) hereof and third, the provisions of Section 7(f)(ii) hereof;
provided, however, that nothing in this Section 7(o) shall be done to evade the principle set forth
in Section 7(f)(x) hereof that the Maximum Conversion Rate shall not apply to any adjustments made
with respect to any of the events in Section 7(f)(i) or Section 7(f)(ii) hereof.

     (p) Successive Adjustments. After an adjustment to the Conversion Rate under Section 7(f)
hereof, any subsequent event requiring an adjustment under Section 7(f) shall cause an adjustment
to the Conversion Rate as so adjusted.

     (q) General Considerations. Whenever successive adjustments to the Conversion Rate are
called for pursuant to this Section 7, such adjustments shall be made to the Market Price as may be
necessary or appropriate to effectuate the intent of this Section 7 and to avoid unjust or
inequitable results as determined in good faith by the Board of Directors.

     (r) Corporation Determination Final. Any determination which the Board of Directors must make
pursuant to this Section 7 shall be conclusive and binding on the Holders.

     8. Mandatory Conversion.

     (a) At any time on or after December 5, 2008, the Corporation shall have the right, at its
option, to cause the Preferred Stock, in whole but not in part, to be automatically converted into
cash and shares of Common Stock equal to the Conversion Value and in accordance with the provisions
of Section 7 hereof. The Corporation may exercise its right to cause a mandatory conversion
pursuant to this Section 8(a) only if the Last Reported Sale Price of the Common Stock equals or
exceeds 130% of the Conversion Price then in effect for at least 20 Trading Days in any consecutive
30-day trading period on the NYSE (or such other national securities exchange or automated
quotation system on which the Common Stock is then listed or authorized for quotation), including
the last Trading Day of such 30-day period, ending on the Trading Day prior to the Corporation’s
issuance of a press release announcing the mandatory conversion as described in Section 8(b).

     (b) To exercise the mandatory conversion right described in Section 8(a), the Corporation must
issue a press release for publication on the Dow Jones News Service prior to the opening of
business on the first trading day following any date on which the conditions described in Section
8(a) are met, announcing such a mandatory conversion. The Corporation shall also give notice by
mail or by publication (with subsequent prompt notice by mail) to the holders of Preferred Stock
(not more than four Business Days after the date of the press release) of the mandatory conversion
announcing the Corporation’s intention to convert the Preferred Stock. The conversion date will be
a date selected by the Corporation (the “Mandatory Conversion Date”) and
will be no more than five days after the date on which the Corporation issues the press
release described in this Section 8(b).

     (c) In addition to any information required by applicable law or regulation, the press release
and notice of a mandatory conversion described in Section 8(b) shall state, as appropriate: (i) the
Mandatory Conversion Date; (ii) the Conversion Value, including the Principal Return, the Net
Shares and the cash in lieu of fractional shares to be delivered upon conversion of the Preferred
Stock; (iii) the number of shares of Preferred Stock to be converted; and (iv) that dividends on
the Preferred Stock to be converted will cease to accumulate on the Mandatory Conversion Date.

     (d) On and after the Mandatory Conversion Date, dividends will cease to accumulate on the
Preferred Stock called for a mandatory conversion pursuant to Section 8(a) and all rights of
holders of such Preferred Stock will terminate except for the right to receive the cash and whole
shares of Common Stock issuable upon conversion thereof and cash, in lieu of any fractional shares
of Common Stock in accordance with Section 7(c). The dividend payment with respect to the Preferred
Stock called for a mandatory conversion pursuant to Section 8(a) on a date during the period
between the close of business on any Dividend Record Date to the close of business on the
corresponding Dividend Payment Date will be payable on such Dividend Payment Date to the record
holder of such share on such Dividend Record Date if such share has been converted after such
Dividend Record Date and prior to

25

 

such Dividend Payment Date. Except as provided in the immediately preceding sentence with respect
to a mandatory conversion pursuant to Section 8(a), no payment or adjustment will be made upon
conversion of Preferred Stock for Accumulated Dividends or for dividends with respect to the Common
Stock issued upon such conversion.

     (e) The Corporation may not authorize, issue a press release or give notice of any mandatory
conversion pursuant to Section 8(a) unless, prior to giving the mandatory conversion notice, all
Accumulated Dividends on the Preferred Stock for periods ended prior to the date of such mandatory
conversion notice shall have been paid in cash.

     (f) In addition to the mandatory conversion right described in Section 8(a), if there are less
than 250,000 shares of Preferred Stock outstanding, the Corporation shall have the right, at any
time on or after December 5, 2008, at its option, to cause the Preferred Stock to be automatically
converted into cash and shares of Common Stock equal to the Conversion Value and in accordance with
the provisions of Section 7 hereof.

     9. Consolidation, Merger and Sale of Assets.

     (a) The Corporation, without the consent of the Holders of any of the outstanding Preferred
Stock, may consolidate with or merge into any other Person or convey, transfer or lease all or
substantially all its assets to any Person or may permit any Person to consolidate with or merge
into, or transfer or lease all or substantially all its properties to, the Corporation; provided,
however, that: (i) the successor, transferee or lessee is organized under the laws of the United
States or any political subdivision thereof; (ii) the shares of Preferred Stock will become shares
of such successor, transferee or lessee, having in respect of such successor, transferee or lessee
the same powers, designations, preferences and relative, participating, optional or other rights on
which, and the qualification, limitations or restrictions thereon, the Preferred Stock had
immediately prior to such transaction; and (iii) the Corporation delivers to the Transfer Agent an
Officers’ Certificate and an Opinion of Counsel stating that such transaction complies with this
Certificate of Designation (including without limitation the requirements of
Section 7(l).

     (b) Upon any consolidation by the Corporation with, or merger by the Corporation into, any
other Person or any conveyance, transfer or lease of all or substantially all the assets of the
Corporation as described in Section 9(a), the successor resulting from such consolidation or into
which the Corporation is merged or the transferee or lessee to which such conveyance, transfer or
lease is made will succeed to, and be substituted for, and may exercise every right and power of,
the Corporation under the shares of Preferred Stock, and, thereafter, except in the case of a
lease, the predecessor (if still in existence) will be released from its obligations and covenants
with respect to the Preferred Stock.

     10. SEC Reports.

     Whether or not the Corporation is required to file reports with the Commission, if any shares
of Preferred Stock are outstanding, the Corporation shall file with the Commission all such reports
and other information as it would be required to file with the
Commission by Section 13(a) or 15(d)
under the Exchange Act. The Corporation shall supply each holder of Preferred Stock, upon request,
without cost to such holder, copies of such reports or other information.

     11. Certificates.

     (a) Form and Dating. The Preferred Stock and the Transfer Agent’s certificate of
authentication shall be substantially in the form of Exhibit C, which is hereby incorporated in and
expressly made a part of this Certificate of Designation. The Preferred Stock certificate may have
notations, legends or endorsements required by law, stock exchange rule, agreements to which the
Corporation is subject, if any, or usage (provided that any such notation, legend or endorsement is
in a form acceptable to the Corporation). Each Preferred Stock certificate shall be dated the date
of its authentication. The terms of the Preferred Stock certificate set forth in Exhibit C are part
of the terms of this Certificate of Designation.

26

 

	 	(i)	 	Global Preferred Stock. The Preferred Stock shall be issued initially in the form of one
or more fully registered global certificates with the global securities legend and restricted
securities legend set forth in Exhibit C hereto (the “Global Preferred Stock”), which shall
be deposited on behalf of the purchasers represented thereby with DTC (or with such custodian
as DTC may direct), and registered in the name of DTC or a nominee of DTC, duly executed by
the Corporation and authenticated by the Transfer Agent as hereinafter provided. The number
of shares of Preferred Stock represented by Global Preferred Stock may from time to time be
increased or decreased by adjustments made on the records of the Transfer Agent and DTC or
its nominee as hereinafter provided. With respect to shares of Preferred Stock that are not
“restricted securities” as defined in Rule 144 under the Securities Act on a Conversion Date,
all shares of Common Stock distributed on such Conversion Date will be freely transferable
without restriction under the Securities Act (other than by affiliates), and such shares will
be eligible for receipt in global form through the facilities of DTC.
	 
	 	(ii)	 	Book-Entry Provisions. In the event Global Preferred Stock is deposited with or on
behalf of DTC, the Corporation shall execute and the Transfer Agent shall authenticate and
deliver initially one or more Global Preferred Stock certificates that (a) shall be
registered in the name of DTC as depository for such Global Preferred Stock or the nominee of
DTC and (b) shall be delivered by the Transfer Agent to DTC or pursuant to DTC’s instructions
or held by the Transfer Agent as custodian for DTC.

Members of, or participants in, DTC (“Agent Members”) shall have no rights under this
Certificate of Designation with respect to any Global Preferred Stock held on their
behalf by DTC or by the Transfer Agent as the custodian of DTC or under such Global
Preferred Stock, and DTC may be treated by the Corporation, the Transfer Agent and any
agent of the Corporation or the Transfer Agent as the absolute owner of such Global
Preferred Stock for all purposes whatsoever. Notwithstanding the foregoing, nothing
herein shall prevent the Corporation, the Transfer Agent or any agent of the Corporation
or the Transfer Agent from giving effect to any written certification, proxy or other
authorization furnished by DTC or impair, as between DTC and its Agent Members, the
operation of customary practices of DTC governing the exercise of the rights of a holder
of a beneficial interest in any Global Preferred Stock.

	 	(iii)	 	Certificated Preferred Stock. Except as provided in Section 11(c), owners of beneficial
interests in Global Preferred Stock will not be entitled to receive Certificated Preferred
Stock.

     (b) Execution and Authentication. Two Officers shall sign the Preferred Stock certificate for
the Corporation by manual or facsimile signature.

     If an Officer whose signature is on a Preferred Stock certificate no longer holds that office
at the time the Transfer Agent authenticates the Preferred Stock certificate, the Preferred Stock
certificate shall be valid nevertheless.

     A Preferred Stock certificate shall not be valid until an authorized signatory of the Transfer
Agent and the Security Registrar manually signs the certificate of authentication on the Preferred
Stock certificate. The signature shall be conclusive evidence that the Preferred Stock certificate
has been authenticated under this Certificate of Designation.

     The Transfer Agent shall authenticate and deliver certificates for 4,910,000 shares of
Preferred Stock for original issue upon a written order of the Corporation signed by two Officers
or by an Officer and an Assistant Treasurer of the Corporation. Such order shall specify the number
of shares of Preferred Stock to be authenticated and the date on which the original issue of
Preferred Stock is to be authenticated.

     The Transfer Agent may appoint an authenticating agent reasonably acceptable to the
Corporation to authenticate the certificates for Preferred Stock. Unless limited by the terms of
such appointment, an authenticating

27

 

agent may authenticate certificates for Preferred Stock whenever the Transfer Agent may do so. Each
reference in this Certificate of Designation to authentication by the Transfer Agent includes
authentication by such agent. An authenticating agent has the same rights as the Transfer Agent or
agent for service of notices and demands.

     (c) Transfer and Exchange of Global Preferred Stock. The transfer and exchange of Global
Preferred Stock or beneficial interests therein shall be effected through DTC, in accordance with
this Certificate of Designation (including applicable restrictions on transfer set forth herein, if
any) and the procedures of DTC therefor.

	 	(i)	 	Restrictions on Transfer and Exchange of Global Preferred Stock.

	 	(A)	 	Notwithstanding any other provisions of this Certificate of Designation (other than
the provisions set forth in Section 11(c)(ii)), Global Preferred Stock may not be
transferred as a whole except by DTC to a nominee of DTC or by a nominee of DTC to DTC or
another nominee of DTC or by DTC or any such nominee to a successor depository or a
nominee of such successor depository.
	 
	 	(B)	 	In the event that the Global Preferred Stock is exchanged for Preferred Stock in
definitive registered form pursuant to Section 11(c)(ii) prior to the effectiveness of a
Shelf Registration Statement with respect to such securities, such Preferred Stock may be
exchanged only in accordance with such procedures as are substantially consistent with
the provisions of this Section 11(c) (including the certification requirements set forth
in the Exhibits to this Certificate of Designation intended to ensure that such transfers
comply with Rule 144A or such other applicable exemption from registration under the
Securities Act, as the case may be) and such other procedures as may from time to time be
adopted by the Corporation.
	 
	 	(C)	 	The Preferred Stock, and any shares of Common Stock distributed pursuant to the
conversion of the Preferred Stock, may not be sold until December 5, 2005, except (a)
pursuant to registration under the Securities Act, (b) in accordance with Rule 144 (if
available) or Rule 144A under the Securities Act (if available) or (c) in offshore
transactions in reliance on Regulation S, and will bear a legend to this effect.

	 	(ii)	 	Authentication of Certificated Preferred Stock. If at any time:

	 	(A)	 	DTC notifies the Corporation that DTC is unwilling or unable to continue as
depository for the Global Preferred Stock and a successor depository for the Global
Preferred Stock is not appointed by the Corporation within 90 days after delivery of such
notice;
	 
	 	(B)	 	DTC ceases to be a clearing agency registered under the Exchange Act and a successor
depository for the Global Preferred Stock is not appointed by the Corporation within 90
days; or
	 
	 	(C)	 	the Corporation, in its sole discretion, notifies the Transfer Agent in writing that
it elects to cause the issuance of Certificated Preferred Stock under this Certificate of
Designation,

then the Corporation will execute, and the Transfer Agent, upon receipt of a written
order of the Corporation signed by two Officers or by an Officer and an Assistant
Treasurer of the Corporation requesting the authentication and delivery of
Certificated Preferred Stock to the Persons designated by the Corporation, will
authenticate and deliver Certificated Preferred Stock equal to the number of shares
of Preferred Stock represented by the Global Preferred Stock, in exchange for such
Global Preferred Stock.

	 	(iii)	 	Cancellation or Adjustment of Global Preferred Stock. At such time as all beneficial
interests in Global Preferred Stock have either been exchanged for Certificated Preferred
Stock, converted or canceled, such Global Preferred Stock shall be returned to DTC for
cancellation or retained and canceled by the Transfer Agent. At any time prior to such
cancellation, if any beneficial interest in

28

 

	 	 	 	Global Preferred Stock is exchanged for Certificated Preferred Stock, converted or canceled,
the number of shares of Preferred Stock represented by such Global Preferred Stock shall be
reduced and an adjustment shall be made on the books and records of the Transfer Agent with
respect to such Global Preferred Stock, by the Transfer Agent or DTC, to reflect such
reduction.

	 	(iv)	 	Obligations with Respect to Transfers and Exchanges of Preferred Stock.

	 	(A)	 	To permit registrations of transfers and exchanges, the Corporation shall execute and the
Transfer Agent shall authenticate Certificated Preferred Stock and Global Preferred Stock as
required pursuant to the provisions of this Section 11(c).
	 
	 	(B)	 	All Certificated Preferred Stock and Global Preferred Stock issued upon any registration
of transfer or exchange of Certificated Preferred Stock or Global Preferred Stock shall be the
valid obligations of the Corporation, entitled to the same benefits under this Certificate of
Designation as the Certificated Preferred Stock or Global Preferred Stock surrendered upon
such registration of transfer or exchange.
	 
	 	(C)	 	Prior to due presentment for registration of transfer of any shares of Preferred Stock,
the Transfer Agent and the Corporation may deem and treat the Person in whose name such shares
of Preferred Stock are registered as the absolute owner of such Preferred Stock and neither
the Transfer Agent nor the Corporation shall be affected by notice to the contrary.
	 
	 	(D)	 	No service charge shall be made to a Holder for any registration of transfer or exchange
upon surrender of any Preferred Stock certificate or Common Stock certificate at the office of
the Transfer Agent maintained for that purpose. However, the Corporation may require payment
of a sum sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Preferred Stock certificates or
Common Stock certificates.
	 
	 	(E)	 	Upon any sale or transfer of shares of Preferred Stock (including any Preferred Stock
represented by a Global Preferred Stock certificate) or of certificated Common Stock pursuant
to an effective registration statement under the Securities Act or pursuant to Rule 144 or
another exemption from registration under the Securities Act (and based upon an Opinion of
Counsel reasonably satisfactory to the Corporation if it so requests):

     (1) in the case of any Certificated Preferred Stock or certificated Common Stock,
the Corporation and the Transfer Agent shall permit the holder thereof to exchange such
Preferred Stock or certificated Common Stock for Certificated Preferred Stock or
certificated Common Stock, as the case may be, that does not bear the restrictive legend
set forth on Exhibit C and rescind any
restriction on the transfer of such Preferred Stock or Common Stock issuable in
respect of the conversion of the Preferred Stock; and

     (2) in the case of any Global Preferred Stock, such Preferred Stock shall not be
required to bear the restrictive legend set forth on Exhibit C; provided, however, that
with respect to any request for an exchange of Preferred Stock that is represented by
Global Preferred Stock for Certificated Preferred Stock that does not bear a restrictive
as set forth on Exhibit C in connection with a sale or transfer thereof pursuant to Rule
144 or another exemption from registration under the Securities Act (and based upon an
Opinion of Counsel if the Corporation so requests), the Holder thereof shall certify in
writing to the Transfer Agent that such request is being made pursuant to such exemption
(such certification to be substantially in the form of Exhibit D hereto).

29

 

	 	(v)	 	No Obligation of the Transfer Agent.

	 	(A)	 	The Transfer Agent shall have no responsibility or obligation to any beneficial owner
of Global Preferred Stock, a member of, or a participant in, DTC or any other Person with
respect to the accuracy of the records of DTC or its nominee or of any participant or
member thereof, with respect to any ownership interest in the Preferred Stock or with
respect to the delivery to any participant, member, beneficial owner or other Person
(other than DTC) of any notice or the payment of any amount, under or with respect to
such Global Preferred Stock. All notices and communications to be given to the Holders
and all payments to be made to Holders under the Preferred Stock shall be given or made
only to the Holders (which shall be DTC or its nominee in the case of the Global
Preferred Stock). The rights of beneficial owners in any Global Preferred Stock shall be
exercised only through DTC subject to the applicable rules and procedures of DTC. The
Transfer Agent may rely and shall be fully protected in relying upon information
furnished by DTC with respect to its members, participants and any beneficial owners.
	 
	 	(B)	 	The Transfer Agent shall have no obligation or duty to monitor, determine or inquire
as to compliance with any restrictions on transfer imposed under this Certificate of
Designation or under applicable law with respect to any transfer of any interest in any
Preferred Stock (including any transfers between or among DTC participants, members or
beneficial owners in any Global Preferred Stock) other than to require delivery of such
certificates and other documentation or evidence as are expressly required by, and to do
so if and when expressly required by, the terms of this Certificate of Designation, and
to examine the same to determine substantial compliance as to form with the express
requirements hereof.

     (d) Replacement Certificates. If a mutilated Preferred Stock certificate is surrendered to the
Transfer Agent or if the Holder of a Preferred Stock certificate claims that the Preferred Stock
certificate has been lost, destroyed or wrongfully taken, the Corporation shall issue and the
Transfer Agent shall countersign a replacement Preferred Stock certificate if the reasonable
requirements of the Transfer Agent are met. If required by the Transfer Agent or the Corporation,
such Holder shall furnish an indemnity bond sufficient in the judgment of the Corporation and the
Transfer Agent to protect the Corporation and the Transfer Agent from any loss which either of them
may suffer if a Preferred Stock certificate is replaced. The Corporation and the Transfer Agent may
charge the Holder for their expenses in replacing a Preferred Stock certificate.

     12. Additional Rights of Holders. In addition to the rights provided to Holders under this
Certificate of Designation, Holders shall have the rights set forth in the Registration Rights
Agreement.

     13. Other Provisions.

     (a) With respect to any notice to a Holder of shares of Preferred Stock required to be
provided hereunder, neither failure to mail such notice, nor any defect therein or in the mailing
thereof, to any particular Holder shall affect the sufficiency of the notice or the validity of the
proceedings referred to in such notice with respect to the other Holders or affect the legality or
validity of any distribution, rights, warrant, reclassification, consolidation, merger, conveyance,
transfer, dissolution, liquidation or winding-up, or the vote upon any such action. Any notice
which was mailed in the manner herein provided shall be conclusively presumed to have been duly
given whether or not the Holder receives the notice.

     (b) Shares of Preferred Stock issued and reacquired will be retired and canceled promptly
after reacquisition thereof and, upon compliance with the applicable requirements of Michigan law,
have the status of authorized but unissued shares of preferred stock of the Corporation
undesignated as to series and may with any and all other authorized but unissued shares of
preferred stock of the Corporation be designated or redesignated and issued or reissued, as the
case may be, as part of any series of preferred stock of the Corporation, except that any issuance
or reissuance of shares of Preferred Stock must be in compliance with this Certificate of
Designation.

30

 

     (c) The shares of Preferred Stock shall be issuable only in whole shares.

     (d) All notice periods referred to herein shall commence on the date of the mailing of the
applicable notice.

     IN WITNESS WHEREOF, the Corporation has caused this certificate to be signed and attested this
15th day of December, 2004.

6. The Certificate of Designation of 4.50% Cumulative Convertible Preferred Stock, Series B, of
CMS Energy Corporation filed on December 20, 2004 is corrected as follows (corrections are in
bold):

          Page 1

          1. Designation and Amount; Ranking.

          (a) There shall be created from the 10,000,000 shares of preferred stock, par value $0.01 per
share, of the Corporation authorized to be issued pursuant to the Articles of Incorporation, a
series of preferred stock, designated as the “4.50% Cumulative Convertible Preferred Stock, Series
B,” par value $0.01 per share (the “Preferred Stock”), and the number of shares of such series
shall be 5,000,000. Such number of shares may be decreased by resolution of the Board of Directors;
provided that no decrease shall reduce the number of shares of Preferred Stock to a number less
than that of the shares of Preferred Stock then outstanding plus the number of shares issuable upon
exercise of options or rights then outstanding. The Preferred Stock was exchanged for 5,000,000 of
then outstanding shares of 4.50% Cumulative Convertible Preferred Stock, par value $0.01 per share
(the “Original Preferred Stock”), established pursuant to the Certificate of Designation of 4.50%
Cumulative Convertible Preferred Stock of CMS Energy Corporation dated December 4, 2003 pursuant to
an exchange offer.

* * *

          Page 3

     A “Fundamental Change” shall be deemed to have occurred at such time after the original
issuance of the Preferred Stock...; provided, however, that a Fundamental Change shall not be
deemed to have occurred in respect of any of the foregoing if either (1) the Last Reported Sale
Price of Common Stock for any five Trading Days within the ten consecutive Trading Days ending
immediately before the later of the Fundamental Change or the public announcement thereof equals
or exceeds 105% of the applicable Conversion Price of the Preferred Stock in effect immediately
before the Fundamental Change or the public announcement thereof (except that this clause (1)
shall not apply to the events described in Section 7(f)(vi) hereof) or (2) at least 90% of the
consideration (excluding cash payments for fractional shares) in the transaction or transactions
constituting the Fundamental Change consists of shares of capital stock traded on a national
securities exchange or quoted on the NASDAQ National Market (or which shall be so traded or
quoted when issued or exchanged in connection with such Fundamental Change) (such securities
being referred to as “Publicly Traded Securities”) and as a result of such transaction or
transactions the Preferred Stock becomes convertible into such Publicly Traded Securities
(excluding cash payments for fractional shares).

* * *

          Page 27

     The Transfer Agent shall authenticate and deliver certificates for 5,000,000 shares of
Preferred Stock for original issue upon a written order of the Corporation signed by two
Officers or by an Officer and an Assistant Treasurer of the Corporation. Such order shall
specify the number of shares of Preferred Stock to be authenticated and the date on which the
