not be less than the par value of the Common Stock. 
  
 SECTION
5.2. Common Stock Reorganization. If the Company shall subdivide its outstanding shares of Common Stock (or any class thereof) into a greater number of shares or consolidate its outstanding shares of Common Stock (or any class thereof) into a
smaller number of shares (any such event being called a “Common Stock Reorganization”), then (a) the Exercise Price shall be adjusted, effective 

  

 10 








 
immediately after the effective date of such Common Stock Reorganization, to a price determined by multiplying the Exercise Price in effect immediately prior
to such effective dare by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding on such effective date before giving effect to such Common Stock Reorganization and the denominator of which shall be the number
of shares of Common Stock outstanding after giving effect to such Common Stock Reorganization, and (b) the number of shares of Common Stock subject to purchase upon exercise of this Warrant shall be adjusted, effective at such time, to a number
determined by multiplying the number of shares of Common Stock subject to purchase immediately before such Common Stock Reorganization by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding after giving
effect to such Common Stock Reorganization and the denominator of which shall be the number of shares of Common Stock outstanding immediately before such Common Stock Reorganization. 
  
 SECTION 5.3. Common Stock Distribution. (a) If the Company shall issue, sell or otherwise distribute any shares of
Common Stock, other than pursuant to a Common Stock Reorganization (which shall be governed by Section 5.2 hereof) (any such event, including any event described in Section 5.3(b) or Section 5.3(c) below, being herein called a “Common Stock
Distribution”), for a consideration per share that is less than the Market Price per share of Common Stock on the date of such Common Stock Distribution, then, effective upon such Common Stock Distribution, the Exercise Price shall be
reduced to the lowest of the prices (calculated to the nearest one-thousandth of one cent) determined as provided in clauses (i), (ii) and (iii) below: 
  
 (i) if the Company shall receive any consideration for the Common Stock issued, sold or distributed in such Common Stock Distribution, the
consideration per share of Common Stock received by the Company upon such issue, sale or distribution; 
  
 (ii) by dividing (A) an amount equal to the sum of (1) the number of shares of Common Stock outstanding immediately prior to such Common
Stock Distribution multiplied by the then existing Exercise Price, plus (2) the consideration, if any, received by the Company upon such Common Stock Distribution by (B) the total number of shares of Common Stock outstanding immediately after such
Common Stock Distribution; and 
  
 (iii) by
multiplying the Exercise Price on the Business Day immediately prior to such Common Stock Distribution by a fraction, the numerator of which shall be the sum of (A) the number of shares of Common Stock outstanding immediately prior to such Common
Stock Distribution multiplied by such Market Price per share on the date of such Common Stock 

  

 11 








 
Distribution, plus (B) the consideration, if any, received by the Company upon such Common Stock Distribution, and the denominator of which shall be the
product of (1) the total number of shares of Common Stock outstanding immediately after such Common Stock Distribution multiplied by (2) the Market Price per share on the date of such Common Stock Distribution. 
  
 If any Common Stock Distribution shall require an adjustment to the Exercise
Price pursuant to the foregoing provisions of this Section 5.3(a), including by operation of Section 5.3(b) or 5.3(c) below, then, effective at the time such adjustment is made, the number of shares of Common Stock subject to purchase upon exercise
of this Warrant shall be increased to a number determined by multiplying the number of shares of Common Stock subject to purchase immediately before such Common Stock Distribution by a fraction, the numerator of which shall be the number of shares
of Common Stock outstanding immediately after giving effect to such Common Stock Distribution and the denominator of which shall be the sum of the number of shares outstanding immediately before giving effect to such Common Stock Distribution (both
calculated on a Fully Diluted Basis) plus the number of shares of Common Stock with the aggregate consideration received by the Company with respect to such Common Stock Distribution would purchase at the Market Price per share of Common Stock on
the date of such Common Stock Distribution. In computing adjustments under this paragraph, fractional interests in Common Stock shall be taken into account to the nearest one-thousandth of a share. 
  
 The provisions of this Section 5.3(a), including by operation of Section
5.3(b) or 5.3(c) below, shall not operate to increase the Exercise Price or reduce the number of shares of Common Stock subject to purchase upon exercise of this Warrant. 
  
 (b) If after the date hereof the Company shall issue, sell, distribute or otherwise grant in any manner (including by
assumption) any rights to subscribe for or to purchase, or any warrants or options for the purchase of Common Stock or any stock or securities convertible into or exchangeable for Common Stock (such rights, warrants or options being herein called
“Options” and such convertible or exchangeable stock or securities being herein called “Convertible Securities”), whether or not such Options or the rights to convert or exchange any such Convertible Securities in
respect of such Options are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such Options or upon conversion or exchange of such Convertible Securities in respect of such Options (determined by
dividing (i) the aggregate amount, if any, received or receivable by the Company as consideration for the granting of such Options, plus the minimum aggregate amount of additional consideration payable to the Company upon the exercise of all such
Options, plus, in the case of Options to acquire Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable 

  

 12 








 
upon the issuance or sale of such Convertible Securities and upon the conversion or exchange thereof, by (ii) the total maximum number of shares of Common
Stock issuable upon the exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options) shall be less than the Market Price per share of Common Stock on the date of granting
such Options, then, for purposes of Section 5.3(a) above, the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total maximum amount of such Convertible Securities
issuable upon the exercise of such Options shall be deemed to have been issued as of the date of granting of such Options and thereafter shall be deemed to be outstanding and the Company shall be deemed to have received as consideration of such
price per share, determined as provided above, therefor. Except as otherwise provided in this Warrant (including Sections 5.3(d) and 5.3(g) below), no additional adjustment of the Exercise Price shall be made upon the actual exercise of any Options
or upon conversion or exchange of any Convertible Securities, notwithstanding any change in the Market Price between the date of issuance, sale, distribution or grant and the date of exercise, conversion or exchange. 
  
 (c) If the Company shall issue, sell or otherwise distribute (including by
assumption) any Convertible Securities, whether or not the rights to exchange or convert thereunder are immediately exercisable, and the price per share for which Common Stock is issuable upon such conversion or exchange (determined by dividing (i)
the aggregate amount received or receivable by the Company as consideration for the issuance, sale or distribution of such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Company upon the
conversion or exchange thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Market Price per share of Common Stock on the date of such
issuance, sale or distribution, then, for purposes of Section 5.3(a) above, the total maximum number of shares of Common Stock issuable upon conversion or exchange of all such Convertible Securities shall be deemed to have been issued as of the date
of the issuance, sale or distribution of such Convertible Securities and thereafter shall be deemed to be outstanding and the Company shall be deemed to have received as consideration such price per share, determined as provided above, therefor.
Except as otherwise provided in this Warrant (including Sections 5.3(d) and 5.3(g) below), no additional adjustment of the Exercise Price shall be made upon the actual conversion or exchange of any Convertible Securities, notwithstanding any change
in the Market Price between the date of issuance, sale or distribution and the date of conversion or exchange. 
  
 (d) If (i) the purchase price provided for in any Option referred to in Section 5.3(b) above or the additional consideration, if any, payable upon the
conversion or exchange of any Convertible Securities referred to in Section 5.3(b) or 

  

 13 








 
5.3(c) above or the rate at which any Convertible Securities referred to in Section 5.3(b) or 5.3(c) above are convertible into or exchangeable for Common
Stock shall change at any time (other than under or by reason of provisions designed to protect against dilution upon an event which results in a related adjustment pursuant to this Article V, in accordance with 5.6(b)), or (ii) any of such Options
or Convertible Securities shall have terminated, lapsed or expired, the Exercise Price then in effect shall forthwith be readjusted (effective only with respect to any exercise of this Warrant after such readjustment) to the Exercise Price which
would then be in effect had the adjustment made upon the issuance, sale, distribution or grant of such Options or Convertible Securities been made based upon such changed purchase price, additional consideration or conversion rate, as the case may
be (in the case of any event referred to in clause (i) of this Section 5.3(d)) or had such adjustment not been made (in the case of any event referred to in clause (ii) of this Section 5.3(d)). 
  
 (e) If the Company shall pay a dividend or make any other distribution upon
any capital stock of the Company payable in Common Stock, Options or Convertible Securities, then, for purposes of Section 5.3(a) above, such Common Stock, Options or Convertible Securities shall be deemed to have been issued or sold without
consideration. 
  
 (f) If any shares of Common Stock, Options or
Convertible Securities shall be issued, sold or distributed for cash, the consideration received therefor shall be deemed to be the amount received by the Company therefor. If any shares of Common Stock, Options or Convertible Securities shall be
issued, sold or distributed for a consideration other than cash, the amount of the consideration other than cash received by the Company shall be deemed to be the Fair Market Value of such consideration, after deduction of any expenses incurred in
connection therewith. If any shares of Common Stock, Options or Convertible Securities shall be issued in connection with any merger in which the Company is the surviving corporation, the amount of consideration therefor shall be deemed to be the
Fair Market Value of such portion of the assets and business of the non-surviving corporation as shall be attributable to such Common Stock, Options or Convertible Securities, as the case may be. If any Options shall be issued in connection with the
issuance and sale of other securities of the Company, together comprising one integral transaction, then such Options shall be deemed to have been issued (i) for such consideration as shall be allocated to such Options by the parties thereto, or
(ii) in the absense of such an allocation by the parties thereto, by a reasonable determination made in good faith by the Board of Directors of the Company, or (iii) in the absence of such an allocation by the parties thereto and such a
determination by the Board of Directors, without consideration. 
  
 (g) The distribution of the Rights pursuant to the Rights Agreement shall not be considered to be a Common Stock Distribution unless both a

“Distribution Date” and a “Section 11(a)(ii) Event” (in each case, as defined in the Rights Agreement) shall have occurred, in which case
the later to occur of such events shall be deemed to constitute an issuance of rights to purchase Common Stock and, therefore, a Common Stock Distribution. If the Company shall enter into a new agreement that is comparable in purpose and effect to
the Rights Agreement (as determined by the Board of Directors of the Company, whose determination shall be conclusive), the execution of the new agreement and a distribution under the new agreement of securities analogous to the distribution of
Series A Junior Participating Preferred Stock under the Rights Agreement shall not be considered to be a Common Stock Distribution but, consistent with the immediately preceding sentence, a Common Stock Distribution shall occur upon the later to
occur of events analogous to a “Distribution Event” and a “Section 11(a)(ii) Event” under the Rights Agreement. 
  
 SECTION 5.4. Special Dividends. If the Company shall issue or distribute to any holder or holders of shares of Common Stock evidences of
indebtedness, any other securities of the Company or any cash, property or other assets (excluding a Common Stock Reorganization or a Common Stock Distribution), whether or not accompanied by a purchase, redemption or other acquisition of shares of
Common Stock (any such nonexcluded event being herein called a “Special Dividend”). (a) the Exercise Price shall be decreased, effective immediately after the effective date of such Special Dividend, to a price determined by
multiplying the Exercise Price then in effect by a fraction, the numerator of which shall be the Market Price per share of Common Stock as of such effective date less any cash and the then fair market value of any evidences of indebtedness,
securities or property or other assets issued or distributed in such Special Dividend with respect to one share of Common Stock, and the denominator of which shall be such Market Price per share and (b) the number of shares of Common Stock subject
to purchase upon exercise of this Warrant shall be increased to a number determined by multiplying the number of shares of Common Stock subject to purchase immediately before such Special Dividend by a fraction, the numerator of which shall be the
Exercise Price in effect immediately before such Special Dividend and the denominator of which shall be the Exercise Price in effect immediately after such Special Dividend. A reclassification 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) into shares of Common Stock and shares of any other class of stock shall be deemed a distribution by the Company to the holders of such Common Stock of such shares of such other class
of stock and, if the outstanding shares of Common Stock shall be changed into a larger or smaller number of shares of Common Stock as part of such reclassification, a Common Stock Reorganization. 
  
 SECTION 5.5. Capital Reorganizations. If there shall be any
consolidation or merger to which the Company is a party, other than a consolidation or a merger of which the Company is the continuing corporation and which does not 

  

 15 








 
result in any reclassification of, or change (other than a Common Stock Reorganization) in outstanding shares of Common Stock, or any sale or conveyance of
the property of the Company as an entirety or substantially as an entirery, or any recapitalization of the Company (any such event being called a “Capital Reorganization”), then effective upon the effective date of such Capital
Reorganization, the Holder shall no longer have the right to purchase Common Stock, but shall have instead the right to purchase, upon exercise of this Warrant, the kind and amount of shares of stock and other securities and property (including
cash) which the Holder would have owned or have been entitled to receive pursuant to such Capital Reorganization if this Warrant had been exercised immediately prior to the effective date of such Capital Reorganization. As a condition to effecting
any Capital Reorganization, the Company or the successor or surviving corporation, as the case may be, shall (a) execute and deliver to each Warrantholder and to the Warrant Agency an agreement as to the Warrantholders right in accordance with this
Section 5.5. providing, to the extent of any right to purchase equity securities hereunder, for subsequent adjustments as nearly equivalent as may be practicable to the adjustments provided for in this Article V and (b) provide each Regulation Y
Holder with an opinion of counsel reasonably satisfactory to such Regulation Y Holder and such other assurances as any Regulation Y Holder may reasonably request to the effect that the ownership and exercise of this Warrant by any Regulation Y
Holder after giving effect to such Capital Reorganization shall not be prohibited by the BHC Act or the regulations thereunder; provided that no such opinion or assurances shall be required if ownership and exercise of this Warrant by such
Regulation Y holder before giving effect to such Capital Reorganization shall be prohibited by the BHC Act or regulations thereunder. The provisions of this Section 5.5 shall similarly apply to successive Capital Reorganizations. 
  
 SECTION 5.6. Adjustment Rules. Any adjustments pursuant to this
Article V shall be made successively whenever an event referred to herein shall occur, except that, notwithstanding any other provision of this Article V; 
  
 (a) no adjustment shall be made to the number of shares of Common Stock to be delivered to each Holder (or to the Exercise Price) if such
adjustment represents less than 1% of the number of shares previously required to be so delivered, but any lesser adjustment shall be carried forward and shall be made at the time and together with the next subsequent adjustment which
together with any adjustments so carried forward shall amount to 1 % or more of the number of shares to be so delivered; 
  
 (b) if any event occurs which shall cause an adjustment to be made pursuant to this Article V and such adjustment shall result in an
adjustment in the conversion price at which a share of Series B Cumulative Convertible Preferred Stock of the Company shall be convertible into Common Stock by 

  

 16 








 
reason of provisions designed to protect the holders thereof against dilution, the resulting adjustment of such conversion price shall not cause any further
adjustment pursuant to this Article V; and 
  
 (c) no adjustment shall be made pursuant to this Article V in respect of the issuance from time to time of shares of Common Stock upon the exercise of any of the Warrants. 
  
 If the Company shall take a record of the holders of its Common Stock for any purpose referred to in this Article V, then (i) such record
date shall be deemed to be the date of the issuance, sale, distribution or grant in question and (ii) if the Company shall legally abandon such action prior to effecting such action, no adjustment shall be made pursuant to this Article V in respect
of such action. 
  
 SECTION 5.7. Proceedings Prior to Any
Action Requiring Adjustment. As a condition precedent to the taking of any action which would require an adjustment pursuant to this Article V, the Company shall take any action which may be necessary, including obtaining regulatory approvals or
exemptions, in order that (a) the Company may thereafter validly and legally issue as fully paid and nonassessable all shares of Common Stock which the holders of Warrants are entitled to receive upon exercise thereof and (b) the ownership and
exercise of any Warrant by any Regulation Y Holder shall not be prohibited by the BHC Act or the regulations thereunder. 
  
 SECTION 5.8. Notice of Adjustment. Not less than 10 nor more than 30 days prior to the record date or effective date, as the case may be, of any
action which requires or might require an adjustment or readjustment pursuant to this Article V, the Company shall give notice to each Warrantholder of such even, describing such event in reasonable detail and specifying the record date or effective
date, as the case may be, and, if determinable, the required adjustment and the computation thereof. If the required adjustment is not determinable at the time of such notice, the Company shall give notice to each Warrantholder of such adjustment
and computation promptly after such adjustment becomes determinable. 
  
 ARTICLE VI 
  
 MISCELLANEOUS 
  
 SECTION 6.1. Notices. Notices and other communications provided for
herein shall be in writing and may be given by mail, courier, confirmed telex or facsimile transmission and shall, unless otherwise expressly required, be deemed given when received or, if mailed, four Business Days after being deposited in the


  

 17 








 
United States mail with postage prepaid and properly addressed. Notices and other communications to the Holder shall be addressed to its address as shown on
the books maintained by the Warrant Agency, unless the Holder shall notify the Warrant Agency that notices and communications should be sent to a different address (or telex or facsimile number), in which case such notices and communications shall
be sent to the address (or telex or facsimile number) specified by the Holder. 
  
 SECTION 6.2. Waivers; Amendments. No failure or delay of the Holder in exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of step to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. No notice or demand on the Company in any case shall entitle the
Company to any other or future notice or demand in similar or other circumstances. The rights and remedies of the Holder are cumulative and not exclusive of any rights or remedies which it would otherwise have. The provisions of this Warrant may be
amended, modified or waived with (and only with) the written consent of the Company and the Majority Holders; provided, however, that no such amendment, modification or waiver shall, without the written consent of the holders of all
Warrants at the time outstanding, (a) change the number of shares of Common Stock subject to purchase upon exercise of this Warrant, the Exercise Price or provisions for payment thereof or (b) amend, modify or waive the provisions of Section 2.5,
this Section 6.2 or Article IV or V. The provisions of the Credit Agreement and the Warrantholders Rights Agreement may be amended, modified or waived only in accordance with the respective provisions thereof. 
  
 Any amendment, modification or waiver effected pursuant to and in accordance
with the provisions of this Section 6.2 or the applicable provisions of the Credit Agreement or the Warrantholders Rights Agreement shall be binding upon the holders of all Warrants and Warrant Shares, upon each future holder thereof and upon the
Company. In the event of any such amendment, modification or waiver the Company shall give prompt notice thereof to all holders of Warrants and Warrant Shares and, if appropriate, notation thereof shall be made on all Warrants thereafter surrendered
for registration of transfer or exchange. 
  
 SECTION 6.3.
GOVERNING LAW. THIS WARRANT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW). 
  
 SECTION 6.4. Transfer; Covenants to Bind Successor and Assigns. All covenants, stipulations, promises and agreements
in this Warrant contained by or on behalf of the Company or the Holder shall bind its successors and assigns, whether 

  

 18 








 
so expressed or not. This Warrant shall be transferable and assignable by the Holder hereof in whole or from time to time in part to any other Person and the
provisions of this Warrant shall be binding upon and inure to the benefit of the Holder hereof and its successors and assigns. 
  
 SECTION 6.5. Severability. In case any one or more of the provisions contained in this Warrant shall be invalid, illegal or unenforceable in any
respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby. The parties shall endeavor in good faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions. 
  
 SECTION 6.6. Section Headings. The section headings used herein are for convenience of reference only, are not part
of this Warrant and are not to affect the construction of or be taken into consideration in interpreting this Warrant.
