immediately prior to giving effect to the amendments provided for
by this Agreement, the "Existing Note Purchase Agreement" and, as
amended pursuant to this Agreement and as may be further amended,
restated  or  otherwise modified from time to time, the  "Amended
Note Purchase Agreement") whereby $30,000,000 aggregate principal
amount  of  Senior Subordinated Notes due November 22,  2006  and
$15,000,000  aggregate  principal amount of  Senior  Subordinated
Notes  due November 22, 2008 (such Notes as in effect immediately

Agreement, the "Existing Notes") of the Company have been  issued
to  you  and are currently outstanding.  The Existing  Notes,  as
amended pursuant to this Agreement and as may be further amended,
restated  or otherwise modified from time to time, together  with
the  2001 Note (as defined below), are referred to herein as  the
"Notes."

2.   DEFINED TERMS.

     Capitalized terms used herein and not otherwise defined have
the  meanings  ascribed  to  them in the  Amended  Note  Purchase
Agreement.

3.   REQUEST FOR CONSENT TO AMENDMENTS; WAIVERS; OVERRIDE.

     3.1. Amendments.

     The  Company requests that you consent to the amendments  to

consent,  agrees  to  issue to you the 2001  Note  and  the  2001
Warrants (as defined below).

     3.2. Waivers.

     Effective  on  (and  subject  to  the  occurrence  of)   the
Amendment No. 4 Effective Date, the Required Holders hereby waive
(the  "Waivers")  any Event of Default caused  by  the  Company's
noncompliance with paragraphs 8A ("Interest Coverage Ratio"),  8B
("Fixed  Charge  Coverage")  and 8C  ("Leverage  Ratio")  of  the
Existing  Note  Purchase Agreement, in each case for  the  fiscal
quarters  of  the Company ended December 31, 2000 and  March  31,
2001,  and  paragraph 8O ("Minimum EBITDA") of the Existing  Note
Purchase  Agreement,  for  any period ended  prior  to  the  date
hereof.

     3.3. Override of Certain Provisions of Existing Note Purchase
          Agreement.

     Subject  to Section 6.3, the effectiveness of the provisions
of  the  Existing  Note Purchase Agreement set forth  below  (the

"Suspension Period") commencing on the Amendment No. 4  Effective
Date (as defined below) and ending on June 29, 2002.  The Company
shall  not  be  required to comply with the Suspended  Provisions
during  the Suspension Period and you shall have no rights  based
on   the  Suspended  Provisions  during  such  period.   At   the
conclusion of the Suspension Period, the Company shall  again  be
required to comply with the Suspended Provisions (effective as of
the  end of the first fiscal quarter of the Company ending  after
the  Suspension  Period,  regardless  of  the  fact  that  fiscal
quarters  and  a fiscal year ending within the Suspension  Period
will  be taken into account in determining such compliance),  and
you  shall have the rights specified in the Amended Note Purchase
Agreement  upon  any failure of the Company so  to  comply.   The
Suspended  Provisions  are  paragraphs  8A  ("Interest   Coverage
Ratio"),  8B ("Fixed Charge Coverage") and 8C ("Leverage Ratio").
All other provisions of the Amended Note Purchase Agreement shall
be  in  full  force  and  effect during  the  Suspension  Period.
Immediately  upon  the conclusion of the Suspension  Period,  the
amendments to the covenants and definition set forth in  Sections
5  and  7 of Part 1 of Exhibit A shall cease to be effective  and
such  covenants and definition, as set forth in the Existing Note
Purchase Agreement, shall be in full force and effect.

          Agreement,  dated  as  of  April  18,   2001,
          pursuant to which the Purchaser has agreed to
          certain amendments to the Note Agreement  and

          Company   has   issued   a   certain   Senior
          Subordinated Note due April 18, 2002, in  the
          aggregate  principal amount of  $900,000,  to

this  Agreement,  the 2001 Note and the 2001 Warrants  (the  2001
Warrants,  together with this Agreement and the  2001  Note,  are

rights  of  the Company or any of its Subsidiaries, by or  before
any  court,  arbitrator or administrative  or  governmental  body
that,  individually  or  in the aggregate,  could  reasonably  be
expected to have a Material Adverse Effect.

     5.3. Transaction Documents Authorized; Obligations Enforceable.

          (a)  Transaction Documents are Legal and Authorized.  The
     execution  and  delivery by the Company of  the  Transaction
     Documents,  and compliance by the Company with  all  of  the
     provisions  of the Amended Note Purchase Agreement  and  the
     Transaction Documents, are within the corporate powers of the
     Company.

          (b)  Company Obligations are Enforceable.  The Company has duly
     authorized the Transaction Documents by all necessary action on
     its part.  This Agreement has been executed and delivered by one
     or more duly authorized officers of the Company, and each of this
     Agreement and the Amended Note Purchase Agreement constitutes,
     and, upon execution and delivery thereof, each of the 2001 Note
     and the 2001 Warrants will constitute, a legal, valid and binding
     obligation of the Company, enforceable in accordance with its
     terms, except that the enforceability thereof may be:

               (i)  limited by applicable bankruptcy, reorganization,
          arrangement, insolvency, moratorium, or other similar laws
          affecting the enforceability of creditors' rights generally; and

               (ii) subject to the availability of equitable remedies.

     5.4. No Conflicts.

     Neither  the  execution  nor  delivery  of  the  Transaction
Documents, nor fulfillment of nor compliance with the  terms  and
provisions  of  the  Amended  Note  Purchase  Agreement  and  the
Transaction Documents will conflict with, or result in  a  breach
of  the  terms,  conditions or provisions  of,  or  constitute  a
default  under, or result in any violation of, or result  in  the
creation of any Lien upon any of the Properties of the Company or
any of its Subsidiaries pursuant to, the charter or bylaws of the
Company  or  any of its Subsidiaries, any award of any arbitrator
or  any  agreement  (including any agreement with  stockholders),
instrument,  order,  judgment,  decree,  statute,  law,  rule  or
regulation  to  which the Company or any of its  Subsidiaries  is
subject.

     5.5. Governmental Consent.

     Neither  the  execution  and  delivery  of  the  Transaction
Documents,  nor the performance by the Company of its obligations
under  the  Amended Note Purchase Agreement and  the  Transaction
Documents,  is  such  as  to require any authorization,  consent,
approval,  exemption or other action by or notice  to  or  filing
with any court or administrative or governmental body (other than
routine  filings  with  the Securities  and  Exchange  Commission
and/or state Blue Sky authorities) on the part of the Company  in
connection  with the execution and delivery of this Agreement  or
fulfillment of or compliance with the terms and provisions of the
Amended Note Purchase Agreement or of the Transaction Documents.

other writings delivered to you by or on behalf of the Company in
connection  with the proposal and negotiation of  the  Amendments
and  Waivers,  taken  as  a  whole, do  not  contain  any  untrue
statement  of a material fact or omit to state any material  fact
necessary to make the statements therein not misleading in  light
of  the  circumstances under which they were made.  There  is  no
fact  known  to the Company that could reasonably be expected  to
have a Material Adverse Effect that has not been set forth herein
or  in  the  other  documents, certificates  and  other  writings
delivered to you by or on behalf of the Company specifically  for

6.    Paragraphs  12A  and  12B  of the  Existing  Note  Purchase
Agreement  are hereby amended and restated in their  entirety  to
read as follows:

          12A. Subordination - General.  Each holder of
     the  Notes and the Company covenant and agree that
     the   Debt   evidenced  by  the  Notes,  including
     principal, Yield-Maintenance Amount, if  any,  and
     interest,   and  expenses  payable   pursuant   to
     paragraph 14B, shall be subordinate and junior  in
     right  of  payment  to  the extent  set  forth  in
     subparagraphs  (i) to (v), below,  to  all  Senior
     Debt.

               (i)  If the Company shall default in the
          payment  of  any principal of or interest  on
          any Senior Debt when the same becomes due and
          payable,  whether at maturity or  at  a  date
          fixed  for  prepayment or by  declaration  of
          acceleration or otherwise, then,  unless  and
          until  such default shall have been  remedied
          by  payment  in  full in cash or  waived,  no
          holder  of the Notes shall accept or  receive
          any  direct  or indirect payment  for  or  on
          account of principal of, or Yield-Maintenance
          Amount, if any, or interest on, the Notes.

               (ii)  In  the  event of any  insolvency,
          bankruptcy,  liquidation,  reorganization  or
          other    similar    proceedings,    or    any
          receivership   proceedings   in    connection
          therewith,  relative to the Company,  and  in
          the  event  of any proceedings for  voluntary
          liquidation, dissolution or other winding  up
          of  the  Company,  whether or  not  involving
          insolvency  or  bankruptcy proceedings,  then
          all  Senior Debt shall first be paid in  full
          in  cash  before any payment is made  by  the
          Company for or on account of principal of, or
          Yield-Maintenance Amount, if any, or interest
          on, the Notes.

               (iii) During the existence of any default described in
          subparagraph (i) above or any proceeding referred to in
          subparagraph (ii) above, any payment or distribution of any kind
          or character, whether in cash, Property, stock or obligations,
          which may be payable or deliverable by the Company in respect of
          the Notes, shall be paid or delivered directly to the Agent (or,
          if the Bank Credit Agreement is no longer in effect, to a banking
          institution selected by the court or Person making the payment or
          delivery or designated by any holder of Senior Debt) for
          application in payment thereof in accordance with the priorities
          then existing among such holders, unless and until all Senior
          Debt shall have been paid in full in cash, provided, however,
          that no such delivery shall be made to holders of Senior Debt of
          stock or obligations which are issued pursuant to  reorganization
          proceedings if such stock or obligations are subordinate and
          junior (whether by law or agreement) at least to the extent
          provided herein to the payment of all Senior Debt then
          outstanding and to the payment of any stock or obligations which
          are issued in exchange or substitution for any Senior Debt then
          outstanding.

               (iv) No holder of the Notes shall accept or receive any direct or
          indirect payment by set-off or otherwise, for or on account of
          the Notes (unless it shall comply with paragraph 12A(v)),

                    (a)    during   the   period   (the
               "Initial Stand-Still Period") commencing
               on  the  Amendment No. 4 Effective  Date
               to, but excluding, the first anniversary
               of such date, or

                    (b)  during a period subsequent to the Initial
               Stand-Still Period (a "Subsequent Stand-Still
               Period" and, together with the Initial Stand-Still
               Period, a "Stand-Still Period") commencing on the
               date of receipt by the Company and the Significant Holders
               of a Stand-Still Notice, and ending on the earliest of

                         (I)   the  date  the  relevant
                    Subordination  Event   of   Default
                    shall have been cured or waived  in
                    writing by the requisite holders of
                    the Senior Debt,

                         (II) the date such Stand-Still
                    Period  shall have been  terminated
                    by  written  notice to the  Company
                    from  the requisite holders of  the
                    Senior Debt, and

                         (III)     the date ninety (90)
                    days  from  the date of receipt  of
                    the applicable Stand-Still Notice.

          Notwithstanding the foregoing, (x) during the
          period   from   and   including   the   first
          anniversary of the Amendment No. 4  Effective
          Date to, but excluding, the same date of  the
          sixth    calendar   month   following    such
          anniversary, no Stand-Still Period  shall  be
          in effect, (y) during any three hundred sixty-
          five  (365) day period, the aggregate  number
          of days during which a Subsequent Stand-Still
          Period may be in effect shall not exceed  one
          hundred  eighty (180) days, and  (z)  in  the
          case of any payment for or on account of  any
          Note  which  would  (in the  absence  of  the
          foregoing clause (a) or the delivery  of  any
          such Stand-Still Notice, as the case may  be)
          have  been due and payable on any date during
          any  Stand-Still  Period, the  provisions  of
          this subparagraph (iv) shall not prevent such
          payment from being made on or after the  date
          immediately  following the last day  of  such
          Stand-Still Period unless another Stand-Still
          Period shall then be in effect.

                (v)  If any payment or distribution  of
          any character, whether in cash, Securities or
          other  Property,  shall be  received  by  any
          holder  of Notes in contravention of  any  of
          the  terms  herein and before all the  Senior
          Debt  shall have been paid in full  in  cash,
          such   payment  or  distribution   shall   be
          received  in  trust for the  benefit  of  the
          holders  of  the  Senior  Debt  at  the  time
          outstanding and shall forthwith be paid  over
          or  transferred to the Agent (or, if the Bank
          Credit  Agreement is no longer in effect,  to
          the holders of Senior Debt).

          12B. Limitation on Remedies.  So long as  any
     Senior  Debt  remains outstanding,  no  holder  of
     Notes may

               (i)  declare or join in the declaration of the Notes to be due
          and payable or otherwise accelerate the maturity of the principal
          of the Notes, accrued interest thereon or other amounts due in
          respect thereof, or

               (ii) commence any administrative, legal or equitable action
          against the Company, including filing or joining in the filing of
          any insolvency petition against the Company,

     prior to the earlier of

               (x)  the fifteenth (15th) day after the date upon which any
          holder of the Notes shall have given written notice to the
          holders of Senior Debt (or the Agent) of their intention to take
          such action, or

               (y)  the acceleration of any Senior Debt;

     provided, however, that no holder of any Notes may
     take  any action described in clause (i) or clause
     (ii)  of  this paragraph 12B during the first  six
     months of the Initial Stand-Still Period (but  may
     take such action at any time thereafter during the
     Initial  Stand-Still Period upon  the  earlier  to
     occur  of the times specified in clauses  (x)  and
     (y)   of  this  paragraph  12B),  or  during   any
     Subsequent  Stand-Still Period,  so  long  as,  in
     either  case, the Senior Debt shall not have  been
     accelerated during any such Stand-Still Period.
