Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to
Securities of the Issuer.

Purchaser  acquired  its initial  interests  in Issuer for  investment  purposes
pursuant to the Stock Purchase  Agreement,  pursuant to which  Purchaser (a) was
entitled to, and did, designate Mark Radzik as Purchaser's representative to the
Issuer's  Board of Directors to be nominated at Issuer's next annual  meeting of
Shareholders  and (b) agreed  that for a period of 18 months  after the  closing
under the Stock Purchase  Agreement  neither  Purchaser nor its affiliates would
(i)  participate in any way in (1) any acquisition of Issuer's  assets,  (2) any
tender or exchange offer, merger or other business combination involving Issuer,
(3) any recapitalization, restructuring or reorganization of Issuer not approved
by Issuer's  Board of Directors or (4) any  solicitation  of a proxy to vote any
voting  securities of Issuer;  (ii) form or join a group (other than through its
representatives  on the  Board of  Directors),  (iii)  otherwise  act to seek to
control or influence the  management of Issuer,  (iv) take any action that might
obligate Issuer to make a public  announcement  regarding any of the matters set
forth in (i) above, or (v) agree to do any of the foregoing.

Issuer filed with the SEC a registration statement on August 1, 2002 effecting a
shelf  registration  of the shares of Issuer's  Common Stock issued to Purchaser
under the Stock Purchase  Agreement  (including  those shares of Issuer's Common
Stock  issuable  upon  conversion  of  the  Class  B  Capital  Stock  issued  to
Purchaser).

Purchaser  has  agreed  that if it  transfers  any of the Class B Capital  Stock
issued to it under the Stock Purchase Agreement to anyone other than a Permitted
Class B Transferee (as defined in the Stock Purchase Agreement), Purchaser shall
be deemed to have exercised the right under the certificate of  incorporation of
Issuer to convert  all shares of Class B Capital  Stock then owned by  Purchaser
and its Permitted Class B Transferees into shares of Issuer's Common Stock.

Issuer  has  agreed  that so long as  Purchaser,  Purchaser's  Permitted  Common
Transferees  (as  defined  in  the  Stock  Purchase  Agreement)  or  Purchaser's
Permitted Class B Transferees own any shares of Issuer's Common Stock or Class B
Capital  Stock,  Issuer  will  not  issue  any  shares  of its  Series  A Junior
Participating  Preferred  Stock,  par  value  $0.01  per  share  (the  "Series A
Preferred"),  other than pursuant to the terms of Issuer's  Shareholder's Rights
Plan,  without  concurrently  offering to  Purchaser  its pro rata share of such
stock based on the voting  percentage  of  Purchaser  and its  Permitted  Common
Transferees  and Permitted  Class B Transferees as of  immediately  prior to the
issuance of the Series A Preferred.

On November 14, 2004, Equity Group Investments,  L.L.C. ("EGI"), an affiliate of
the Purchaser, confirmed that the letter agreement dated May 3, 2002 between the
Issuer and EGI for the  provision of certain  advisory  services was  terminated
effective the date thereof.
