         NOW  THEREFORE,  in  consideration  of the  premises and other good and
valuable consideration, the parties hereto hereby agree as follows:



         1.01 Joinder of Companies.

         (a)  Joinder.  Pursuant to Section 8.17 of the Credit  Agreement,  each
Company hereby agrees that it is a Borrower  under the Credit  Agreement as if a
signatory thereof on the Closing Date, and such Company shall comply with and be
subject  to and have the  benefit of all of the  terms,  conditions,  covenants,
agreements and  obligations  set forth therein.  Each Company hereby agrees that
each reference to a "Borrower" or the  "Borrowers"  in the Credit  Agreement and
other Loan Documents shall include such Company.  Each Company acknowledges that
it has  received  a copy  of the  Credit  Agreement  and  that it has  read  and
understands the terms thereof.

         (b)  Schedules.  Attached  hereto are updated  copies of each  Schedule
referenced in the Credit Agreement  revised to include all information  required
to be provided therein with respect to (and only with respect to) each Company.

         2.01 Effectiveness.  This Agreement shall become effective upon receipt
by the Administrative  Agent of (i) an originally  executed Note for each Lender
jointly  executed by each  Borrower  and each  Company in exchange for the Notes
issued on the Closing Date or the date of the most recent Joinder Agreement,  as
applicable,  (ii) an originally executed  counterpart hereof and (iii) any other
agreement or document  delivered  in  accordance  with Section 8.17  (including,
without limitation, any Security Document required to be executed thereunder).

         3.01 General Provisions.

         (a) Representations and Warranties.  Each Borrower hereby confirms that
each representation and warranty made by it under the Loan Documents is true and
correct in all  material  respects  as of the date hereof and that no Default or
Event of Default  has  occurred  or is  continuing  under the Credit  Agreement,
except for any deviations  from such  representations  and warranties  expressly
permitted  by  the  Credit   Agreement  and  except  for  any  waivers  of  such
representations and warranties granted by the Required Lenders in writing.  Each
such Borrower  hereby  represents  and warrants that as of the date hereof there
are no  claims  or  offsets  against  or  defenses  or  counterclaims  to  their
respective obligations under the Credit Agreement or any other Loan Document.

         (b) Limited Effect. Except as supplemented hereby, the Credit Agreement
and each other Loan Document  shall  continue to be, and shall  remain,  in full
force and effect.  This Agreement  shall not be deemed (i) to be a waiver of, or
consent to, or a  modification  or amendment  of, any other term or condition of
the  Credit  Agreement  or (ii) to  prejudice  any  right or  rights  which  the
Administrative  Agent or Lenders may now have or may have in the future under or
in  connection  with the Credit  Agreement  or the Loan  Documents or any of the
instruments  or  agreements  referred to therein,  as the same may be amended or
modified from time to time.

         (c) Costs and  Expenses.  The  Borrowers  hereby  jointly and severally
agree to pay or reimburse the Administrative Agent for all of its reasonable and
customary  out-of-pocket  costs and  expenses  incurred in  connection  with the
preparation,  negotiation  and execution of this  Agreement  including,  without
limitation, the reasonable fees and disbursements of counsel.

         (d) Counterparts.  This Agreement may be executed by one or more of the
parties  hereto  in  any  number  of  separate  counterparts  and  all  of  said
counterparts  taken  together  shall be  deemed to  constitute  one and the same
instrument.


                                       2


         (e)  Definitions.  All  capitalized  terms used and not defined  herein
shall have the meanings given thereto in the Credit Agreement.

         (f) Governing Law. THIS  AGREEMENT  SHALL BE GOVERNED BY, AND CONSTRUED
AND  INTERPRETED IN ACCORDANCE  WITH,  THE LAWS OF THE STATE OF NORTH  CAROLINA,
WITHOUT REFERENCE TO THE CONFLICTS OR CHOICE OF LAW PRINCIPLES THEREOF.
