                                       2

                    Interest  charges shall be computed on the actual  principal
                    amount of Advances  outstanding  during the  calendar  month

                    any change therein after the date of this Agreement, (b) any
                    change   after   the   date   of  this   Agreement   in  the
                    interpretation or administration of any law, treaty, rule or

                    authority or (c) the  compliance by the Lender or the Issuer
                    with any  guideline,  request or directive  from any central
                    bank or other governmental  authority (whether or not having
                    the  force of Law)  after  the date of this  Agreement  (for
                    purposes  of this  Section  3.7,  the  term  "Lender"  shall
                    include the Lender and any  corporation or bank  controlling
                    the Lender), shall:

                         (a)   subject  the  Lender  to  any  tax  of  any  kind
                    whatsoever  with  respect  to this  Agreement  or any  Other
                    Document  or change the basis of taxation of payments to the
                    Lender of  principal,  fees,  interest  or any other  amount
                    payable  hereunder or under any Other Documents  (except for
                    changes in the rate of tax on the  overall net income of the
                    Lender  by  the  jurisdiction  in  which  it  maintains  its
                    principal office);

                                       3

                         (b)  impose,  modify or hold  applicable  any  reserve,
                    special deposit,  assessment or similar  requirement against
                    assets  held  by,  or  deposits  in or for the  account  of,
                    advances  or loans  by, or other  credit  extended  by,  any
                    office  of  the  Lender,   including  (without   limitation)
                    pursuant to  Regulation  D of the Board of  Governors of the
                    Federal Reserve System; or

                         (c)  impose  on the  Lender  any other  condition  with
                    respect to this Agreement or any Other Document;

                         and the result of any of the  foregoing  is to increase
                    the cost to the Lender of making,  renewing  or  maintaining
                    its Advances hereunder by an amount that the Lender deems to
                    be material or to reduce the amount of any payment  (whether
                    of  principal,  interest or  otherwise) in respect of any of
                    the  Advances  by an  amount  that  the  Lender  deems to be
                    material, then, in any case the Borrowers shall promptly pay
                    the Lender,  upon its demand, such additional amount as will
                    compensate  the  Lender  for  such  additional  cost or such
                    reduction,  as the case may be. The Lender shall certify the
                    amount  of such  additional  cost or  reduced  amount to the
                    Borrowers,  and such certification shall be presumed correct
                    absent manifest error.

     7. Section 3.8 of the Credit  Agreement  is hereby  deleted in its entirety
and in its stead is inserted the following:

                    (a) the introduction after the date of this Agreement of any
                    law, treaty,  rule or regulation or any change therein after
                    the date of this Agreement, (b) any change after the date of
                    this Agreement in the  interpretation  or  administration of
                    any law,  treaty,  rule or regulation by any central bank or
                    other  governmental  authority or (c) the  compliance by the
                    Lender  or  the  Issuer  with  any  guideline,   request  or
                    directive  from  any  central  bank  or  other  governmental
                    authority (whether or not having the force of Law) after the
                    date of this  Agreement  (for  purposes of this Section 3.9,
                    the  term   "Lender"   shall  include  the  Lender  and  any

                                       4

                    corporation or bank  controlling  the Lender),  has or would
                    have  the  effect  of  reducing  the rate of  return  on the
                    Lender's   capital  as  a  consequence  of  its  obligations
                    hereunder  to a level below that which the Lender could have
                    achieved but for such adoption, change or compliance (taking
                    into  consideration  the Lender's  policies  with respect to
                    capital  adequacy)  by an amount  deemed by the Lender to be
                    material,  then,  from time to time, the Borrowers shall pay
                    upon demand to the Lender such additional  amount or amounts
                    as will compensate the Lender for such reduction.

                    examinations  and  appraisals  shall be in the discretion of
                    the Lender,  be  conducted  by an  independent  examiner and

     14. The provisions of Sections 2 through 13 and 15 of this Third  Amendment
shall not become effective until the Lender has received the following,  each in
form and substance acceptable to the Lender:

                         (a) this Third  Amendment,  duly  executed by each Loan
                    Party, the Lender and the Issuer;

                         (b)  an  amendment/waiver  fee  in  the  amount  of Ten

not less than 1.10 to 1.00  calculated as of the last day of the fiscal  quarter
ending June 30, 2007,  for the period equal to the four (4)  consecutive  fiscal

Agreement or the Other Documents, as applicable.

     17.  Each  Loan  Party  acknowledges  and  agrees  that,  except  for  such

execution  and  delivery  hereof by such  Loan  Party  and the  performance  and
observance by such Loan Party of the provisions  hereof and all other  documents
executed  or to be  executed  herewith,  do not  violate  or  conflict  with the

     19. Each Loan Party represents and warrants that (i) except as set forth in

by the different parties hereto on separate  counterparts each of which, when so
executed,  shall  be  deemed  an  original,  but  all  such  counterparts  shall

of Allegheny  County,  Pennsylvania and the United States District Court for the
Western  District of  Pennsylvania  with  respect to any suit  arising out of or
mentioning this Third Amendment.
