         $40,000,000,   plus  (ii)  fifty  percent   (50%)  of  the   cumulative
         Consolidated  Net Income for each  quarter  beginning  after the fiscal
         quarter  ending  on June  30,  2000  (specifically  not  including  any
         Consolidated  Net  Loss  for  any  fiscal  quarter),   plus  (iii)  the
         cumulative  net  proceeds  of all equity  offerings,  except for the 8%

         Preferred  Stock") and (b) common stock of up to $10,000,000  (the "New
         Common Stock"),  provided,  however,  that such New Preferred Stock and
         New Common Stock is issued on or before January 31, 2001 and,  provided
         further,   that  the  definitions  of  "Consolidated   Net  Worth"  and
         "Indebtedness"  and Section  8.09 (c) in the Senior  Subordinated  Note
         Purchase  Agreement are amended upon terms and conditions  satisfactory
         in all respects to the Required Lenders."

2.       Conditions  Precedent.  This  Amendment  shall  become  effective  upon

         a. The Agent shall have received one or more duly executed counterparts
of this Amendment signed by each of the parties hereto.

         b. The Agent shall have received such other documents as any Lender may

3.       Other Agreements.

         a. The Company  hereby  affirms  that each of the  representations  and
warranties  of the Company  contained in the Credit  Agreement  and in any other
Loan Documents  (except to the extent that any such  representation  or warranty
expressly relates solely to an earlier date and for changes therein permitted or
contemplated by the Credit Agreement) is correct in all material respects on and
as of the date hereof and after giving  effect to this  Amendment.  In addition,

constitute  a default  under or  accelerate  any  performance  required  by, any
indenture,  mortgage,  deed of trust,  lease,  agreement or other  instrument to
which the Company is a party or by which the  Company or any of its  property is
bound;  (vi) will not result in the creation or  imposition of any Lien upon any

benefit of the  Lenders,  all pursuant to the Loan  Documents;  and (vii) do not
require the consent or approval of any Governmental  Authority.  Company further
represents and warrants that this Amendment has been duly executed and delivered
for the benefit of or on behalf of the Company and  constitutes  a legal,  valid
and  binding  obligation  of the  Company,  enforceable  against  the Company in
accordance with its terms.

         b. As amended hereby,  all terms of the Credit  Agreement and the other
Loan Documents shall be and remain in full force and effect and shall constitute
the legal,  valid,  binding and  enforceable  obligations  of the Company to the
Agent and the Lenders.  To the extent any terms and conditions in any other Loan
Documents shall contradict or be in conflict with any terms or conditions of the
Credit  Agreement,  after  giving  effect  to this  Amendment,  such  terms  and
conditions  are hereby deemed  modified and amended  accordingly  to reflect the
terms and conditions of the Credit Agreement as modified and amended hereby.

         c. The Company hereby  restates,  ratifies and reaffirms each and every
term and  condition  set  forth  in the  Credit  Agreement  and the  other  Loan
Documents,  effective as of the date hereof,  and represents  that, after giving
effect to this  Amendment,  no Default or Event of Default has  occurred  and is
continuing as of the date hereof.

         d. The Lenders  agree that the first  installment  of the amendment fee
payable by the Company pursuant to Section 3(d) of that certain Fourth Amendment
to Amended and Restated Revolving Credit Facility dated as of September 28, 2000
by and among the Company and the Lenders (the "Fourth  Amendment") has been paid
in full and that the second installment of the amendment fee pursuant to Section
3(d) of the Fourth  Amendment  shall be due and payable on or before February 1,
2001;  provided  however,  if the New Preferred Stock and/or New Common Stock is
issued on or before January 31, 2001, then the Lenders agree to waive payment of
such second installment.

         e. The  Company  agrees to pay on demand all costs and  expenses of the
Agent in connection with the preparation, execution, delivery and enforcement of
this Amendment,  the closing  hereof,  and any other  transactions  contemplated
hereby, including the fees and out-of-pocket expenses of the Agent's counsel. In
addition,  the  Company  agrees  to pay all  legal  fees and  expenses  actually
incurred  through  the date  hereof  to the  Agent or  Agent's  counsel,  King &
Spalding, on or before December 10, 2000.

         f. This Amendment may be executed in any number of  counterparts,  each
of which shall be deemed an original  and all of which,  taken  together,  shall
constitute one and the same instrument.
