      arising out of, relating to or resulting from any of the
      following:

      or circumstances that occur on or after the Closing and which relate to

      to the proviso below, the Agreement Approving Asset Sale with the Central
      States, Southeast and Southwest Areas Pension Fund, dated March 30, 2007
      (the “Central States Agreement”), including without limitation (A) the USC

      Agreement that are attributable to a drop in CBUs (as defined in the
      Central States Agreement), whether with respect to periods prior to or
      after the Closing; and (B) the secondary liability obligations of the USC

              USC’s

      Clawson employees of Superior and its affiliates pursuant to the
      collective bargaining agreement between Superior Materials, LLC and
      Teamster’s Local Union No. 614 (the “Union Employees”);

              the
      Issuance.

            

    

     

    provided
that to the extent such New Joint Venture Partner executes a Joinder Agreement
in accordance with Section 16 below and
the closing of the Issuance shall occur, Levy’s liability shall not exceed an
amount equal to a percentage of such Adverse Consequences equal to Levy’s
ownership interest in Superior as set forth in the Joinder Agreement and the
liability of the New Joint Venture Partner shall not exceed an amount equal to a
percentage of such Adverse Consequences equal to the New Joint Venture Partner’s
ownership interest in Superior as set forth in the Joinder
Agreement.  For the avoidance of doubt, Levy’s percentage interest of
the Adverse Consequences together with the New Joint Venture Partner’s
percentage of Adverse Consequences shall equal 100%.  USC and Joint
Venture Partners represent and warrant that, as of the date hereof and as of the
date of the Closing (the “Closing Date”), they are not aware of any facts or
circumstances that could give rise to any obligations or liabilities of
Superior, USC and/or the Joint Venture Partners under the Central States
Agreement.

indemnification provided in this Section 2.a. shall be
subject to the terms set forth in Annex A

      obligations under the Contribution Agreement effective as of the
      Closing.

financial advisor shall enter into a confidentiality agreement (the
“Confidentiality Agreement”) with Levy and the New Joint Venture Partner
reasonably satisfactory to Levy and the New Joint Venture
Partner.  The Confidentiality Agreement shall authorize such financial
advisor, its employees, agents, officers, directors and employees (collectively,
the “Authorized Representatives”) to conduct the Due Diligence Review on behalf
of USC and the Joint Venture Partners and to prepare and deliver an opinion to
USC and the Joint Venture Partners summarizing their findings; provided, that
the Authorized Representatives may not disclose the contents of the materials
provided by Levy or the New Joint Venture Partner in the Due Diligence Review to
USC or the Joint Venture Partners or any other third party (other than another
Authorized Representative).

    

    4.           Negotiation of Final
Forms.

    

    a.           From
the date hereof through and including August 18, 2010 (as may be extended from
time to time by the mutual agreement of the parties, the “Negotiation End
Date”), the parties hereto shall endeavor to negotiate mutually acceptable forms
of amendments, assignments or terminations with respect to each of the
agreements set forth on Schedule II hereto
(collectively with the agreement named on Schedule I attached
hereto, the “Ancillary Agreements”) to which they are a party.

     

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

    

    b.           On
the Negotiation End Date, the parties hereto shall execute a counterpart to this
Agreement (the “Supplement”) setting forth the final, agreed upon form of the
amendment or assignment to or termination of, as applicable, each of the
Ancillary Agreements (collectively, the “Final Forms”); provided, that the
parties hereto may not reach agreement with respect to one or more Final Forms,
in which case the related Ancillary Agreement(s) shall continue in full force
and effect after the Closing (as in effect immediately prior to the Closing) and
the parties shall not enter into the related Final Form(s).

     

    c.           In
the event that the parties hereto fail to (i) execute the Supplement or (ii)
create a Final Form with respect to any Ancillary Agreement (as attached to a
fully executed Supplement), in each case, on or prior to the Negotiation End
Date, any party hereto may terminate this Agreement upon 10 days’ prior written
notice to the other parties pursuant to Section 20(e),
subject to the survival provisions contained herein.

     

    5.           Issuance.

    

    a.           In
the event that Superior has not consummated the Issuance on or prior to
September 30, 2010, Levy may terminate this Agreement by providing written
notice to the other parties hereto pursuant to Section 20(f),
provided that the notice must be provided by 12:00 p.m. midnight Eastern
Daylight Time on September 30, 2010 (the “Issuance Agreement
Deadline”).

    

    b.           Subject
to the satisfaction of the conditions in Section 6 below, the Joint Venture
Partners and USC hereby approve the Issuance and the Redemption and will vote
and/or cause to vote the Shares owned by the Joint Venture Partners in favor of
the Issuance and the Redemption.

    

    6.           Conditions to
Closing.

              i.

            	
              Levy’s
      and Superior’s consummation of the Issuance with the New Joint Venture
      Partner providing for the Issuance on terms satisfactory to Levy;
      provided, that if this condition is not met or waived on or before the
      Issuance Agreement Deadline, it shall no longer be applicable unless Levy
      has terminated this Agreement in accordance with Section 20(f)
      on or before the Issuance Agreement Deadline;
  and

            

    

     

    
      	
               
      

            	
              ii.

            	
              USC
      and each Joint Venture Partner, as applicable, shall have executed and
      delivered to Levy counterparts to each Final Form to which it is a
      party.

            

    

     

    b.           The
obligations of the Joint Venture Parties to close the Redemption shall be
subject to satisfaction of the following conditions prior to or concurrently
with the Closing, which conditions may be waived by USC in its sole
discretion:

     

    
      	
               
      

            	
              i.

            	
              the
      approval by the U.S. Bankruptcy Court of the entry by USC into this
      Agreement and the other agreements, amendments and documents contemplated
      herein by August 20, 2010; provided, that USC may not waive this
      condition; and

              ii.

            	
              Levy,
      Superior and the New Joint Venture Partner, as applicable, shall have
      executed and delivered to USC counterparts to each Final Form to which it
      is a party.

            

    

     

    c.           The
obligation of each of the parties is subject to the condition that no action,
suit, or proceeding shall be pending before any court or quasi-judicial or
administrative agency of any federal, state, local, or non-U.S. jurisdiction
wherein an unfavorable injunction, judgment, order, decree, ruling, or charge
would (A) prevent consummation of any of the transactions contemplated by this
Agreement or (B) cause any of the transactions contemplated by this Agreement to
be rescinded following consummation (and no such injunction, judgment, order,
decree, ruling, or charge shall be in effect).

    

    d.           USC
and each of the Joint Venture partners hereby agree to use their commercially
reasonable best efforts to obtain the approval by the U.S. Bankruptcy Court of
the entry by USC into this Agreement and the other agreements, amendments and
documents contemplated herein by August 20, 2010.

              (a)

      Partner (as defined in the Operating Agreement); provided that the

      subsidiaries shall survive the Redemption and shall not be amended,
      repealed or otherwise modified in any manner that would adversely affect

  Party.

              In
      connection with the exercise by Levy of its Section 5.4 rights under
      Section 2(i) of this Agreement, USC and the Joint Venture Partners hereby
      (on behalf of itself and its affiliates) waive, release and agree not to
      assert any claim, defense or position that USC’s emergence from bankruptcy
      on or before the Section 5.4 End Date in any way adversely affects Levy’s
      right to exercise such rights.  Upon the consummation of the
      Closing, Levy hereby agrees to waive all of its rights under Section 5.4
      of the Operating Agreement with respect to any period before, on or after
      the Closing.

interest in, making an investment in or becoming a creditor of, or providing any
credit to, any business which conducts the Business in the State of
Michigan.  Notwithstanding the foregoing, the restrictions in this
Section 9 shall
not prohibit any Joint Venture Partner, USC or any of their respective
affiliates from disposing, transferring or selling any asset to any party
(including for consideration consisting in whole or in part of debt
instruments), supplying materials or supplies to any party (including on
credit), purchasing materials or supplies from any party (including on credit)

added, alternative or add-on minimum, estimated, or other tax of any kind
whatsoever, including any interest, penalty, or addition thereto, whether
disputed or not and including any obligations to indemnify or otherwise assume
or succeed to the Tax liability of any other Person.

     

    
      	
              2.

            	
              If
      any third party notifies any USC Indemnified Party with respect to any
      matter (a ‘‘Third-Party
      Claim’’) that may give rise to a claim for indemnification against
      any Indemnifying Party under Section 2.a. of the Redemption Agreement,
      then the USC Indemnified Party shall promptly notify each Indemnifying
      Party thereof in writing; provided, however, that no delay on the part of
      the USC Indemnified Party in notifying any Indemnifying Party shall
      relieve the Indemnifying Party from any obligation hereunder unless (and
      then solely to the extent) the Indemnifying Party is thereby
      prejudiced.

            

    

     

    
      	
              3.

            	
              Any
      Indemnifying Party will have the right to defend the USC Indemnified Party
      against the Third-Party Claim with counsel of his, her, or its choice
      satisfactory to the USC Indemnified Party so long as (A) the Indemnifying
      Party notifies the USC Indemnified Party in writing within 15 days after
      the USC Indemnified Party has given notice of the Third-Party Claim that
      the Indemnifying Party will indemnify the USC Indemnified Party from and
      against the entirety of any Adverse Consequences the USC Indemnified Party
      may suffer resulting from, arising out of, relating to, in the nature of,
      or caused by the Third-Party Claim, (B) the Indemnifying Party provides
      the USC Indemnified Party with evidence acceptable to the USC Indemnified
      Party that the Indemnifying Party will have the financial resources to
      defend against the Third-Party Claim and fulfill its indemnification
      obligations hereunder, (C) the Third-Party Claim involves only money
      damages and does not seek an injunction or other equitable relief, (D)
      settlement of, or an adverse judgment with respect to, the Third Party
      Claim is not, in the good faith judgment of the USC Indemnified Party,
      likely to establish a precedential custom or practice adverse to the
      continuing business interests or the reputation of the USC Indemnified
      Party, and (E) the Indemnifying Party conducts the defense of the
      Third-Party Claim actively and
diligently.

            

    

     

    
      
        
        

      

      
        A-1

        
          

        

      

      
        
        

      

    

     

    
      	
              4.

            	
              So
      long as the Indemnifying Party is conducting the defense of the
      Third-Party Claim in accordance with paragraph 3 above, (A) the USC
      Indemnified Party may retain separate co-counsel at his, her, or its sole
      cost and expense and participate in the defense of the Third-Party Claim,
      (B) the USC Indemnified Party will not consent to the entry of any
      judgment on or enter into any settlement with respect to the Third-Party
      Claim without the prior written consent of the Indemnifying Party (not to
      be unreasonably withheld), and (C) the Indemnifying Party will not consent
      to the entry of any judgment on or enter into any settlement with respect
      to the Third-Party Claim without the prior written consent of the USC
      Indemnified Party (not to be unreasonably
  withheld).

            

    

     

    
      	
              5.

            	
              In
      the event any of the conditions in paragraph 2 above is or becomes
      unsatisfied, however, (A) the USC Indemnified Party may defend against,
      and consent to the entry of any judgment on or enter into any settlement
      with respect to, the Third-Party Claim in any manner his, her, or it may
      deem appropriate (and the USC Indemnified Party need not consult with, or
      obtain any consent from, any Indemnifying Party in connection therewith),
      (B) the Indemnifying Parties will reimburse the USC Indemnified Party
      promptly and periodically for the costs of defending against the
      Third-Party Claim (including attorneys’ fees and expenses), and (C) the
      Indemnifying Parties will remain responsible for any Adverse Consequences
      the USC Indemnified Party may suffer resulting from, arising out of,
      relating to, in the nature of, or caused by the Third-Party
      Claim.
