and agree with Superior  that  except  for the Superior Securities acquired
pursuant to the Merger Agreement, no member  of  the  First  Reserve  Group
shall,  directly  or  indirectly,  acquire  any Superior Securities, if the
effect of such acquisition, agreement or other  action would be to increase

recapitalization with respect to such Superior  Securities)  to 10% or more

Securities  to  another  member  of the First Reserve Group that has signed

First Reserve Fund; provided that any distributee that is  a  member of the
First  Reserve Group has signed this Agreement; and provided, further  that
any arrangements  coordinated  or  initiated  by  or  on  behalf of a First
Reserve  Fund   to  assist  its  limited  partners in the sale of  Superior

members of the First Reserve Group selling, transferring or disposing  such
Superior  Securities  shall, unless the Board consents otherwise, use their
reasonable best efforts  to refrain from knowingly selling, transferring or

right to acquire or ownership of 5% or more of the Voting  Power to any one
Person or group of Persons.

     Section  3.3       PROXY SOLICITATIONS.  As a stockholder,  the  First

Incentive  Plan), publicly disclose  any  intention,  plan  or  arrangement
inconsistent  with  the foregoing, or initiate, induce or attempt to induce
any other Person to initiate  any  proposal that can reasonably be expected

this Section 3.5, on and after the eleventh business day after commencement
of a tender or exchange offer made by a Person who  is  not a member of the
First  Reserve  Group  for  outstanding Superior Securities (a  "Qualifying
Offer"), any member of the First  Reserve  Group may tender or exchange any
Superior Securities beneficially owned by it  pursuant  to  such Qualifying
Offer,  provided  the  Qualifying  Offer shall have been approved,  or  not

then, from and after the eleventh business day after commencement  of  such
Qualifying  Offer,  any  member  of  the  First Reserve Group may tender or

only  if  (i)  no  tender or exchange of, or indication of an intention  to
tender or exchange,  Superior Securities is made by any member of the First
Reserve Group earlier  than  24  hours  prior to the expiration of any time
after which Superior Securities tendered may be treated less favorably than
other Superior Securities tendered or exchanged  prior  thereto, and (ii) a
binding agreement is reached with the bidder or offeror prior to any tender
or  exchange  specifying  that  only  such  number  of Superior  Securities
submitted for tender or exchange shall be accepted by the bidder or offeror
as  are  equal  to  (A)  the  percentage  of  such Superior Securities  not
beneficially owned by the First Reserve Group that  have  been  tendered or
exchanged,  multiplied  by (B) the total number of such Superior Securities
beneficially  owned  by  the   member   of   the   First   Reserve   Group.
Notwithstanding  the  foregoing,  the  provisions of this Section 3.5 shall
terminate upon the earlier of the fifth  anniversary  of  this Agreement or
such time as the First Reserve Group beneficially owns less than 15% of the
Voting Power.

     Section   3.6        LIMITATION  ON  COVENANTS.  Notwithstanding   any
provision to the contrary in  this  Agreement,  during  any period that any
person  designated  by the First Reserve Funds to serve as  a  Director  in
accordance with the provisions  of  Section  2.1(b)  is  not  serving  as a
Director as a result of the failure of Superior or the Board to comply with
the  terms of this Agreement, or if any such designee is not elected by the
stockholders  (and Section 2.1(b) is complied with), then the covenants set
forth in this Article  3  shall  cease  to be effective during such period;
provided, however, that if a person designated  by  the First Reserve Funds
ceases  to  be  a  Director  by  reason of death or resignation,  then  the
provisions of this Section 3.6 shall  not apply if the Board appoints First
Reserve Funds' designated replacement to  fill  an  such  vacancy within 15
business  days  after  Superior  receives notice of such designation.   The
provisions of this Section 3.6 shall  be  in addition to any other remedies

provisions of Article 2 hereof.

Securities,  to  the refusal by Superior to transfer  any  such  securities
except in compliance  with  the  requirements  of this Agreement.  Superior

to the transfer of Superior Securities being made  to  a  Person who is not
then a member of the First Reserve Group in compliance with  the provisions
of this Agreement.
