         As a condition to the  willingness of Parent and Merger  Subsidiary to
enter into the Prism Merger Agreement,  Parent and Merger  Subsidiary  required
ABRY Mezzanine  Partners,  L.P.,  ABACUS Fund Partners,  LP, ABACUS Fund, Ltd.,
Sandler Capital Partners V Germany,  L.P., Sandler Capital Partners V FTE, L.P.
and Sandler Capital Partners V, L.P. (each  individually a  "Stockholder",  and

cause to be voted)  all shares of  Company  capital  stock held by them and any

exchange offer, reorganization, recapitalization, liquidation, sale or transfer
of all or substantially  all of the assets or securities of the Company and any
of is  subsidiaries,  other than  pursuant  to the Prism  Merger,  or any other
acquisition proposal.

         As part of the Voting  Agreement,  the  Stockholders  entered  into an
irrevocable proxy appointing Parent and certain of its officers or designees as
the sole and exclusive  attorneys and proxies of each  Stockholder  to vote and
exercise  all voting and related  rights  with  respect to all of the shares of
Company  capital stock that now are or hereafter may be  beneficially  owned by
the Stockholders.

         Pursuant to the Voting Agreement, the Stockholders are prohibited from
transferring any shares of Company capital stock.

         The Voting Agreement and the irrevocable  proxies will expire upon the
earliest to occur of (i) the effective time of the Prism Merger,  (ii) the date
on which the Prism Merger  Agreement is terminated  pursuant to its terms (iii)
April 30, 2007 and (iv) written notice of  termination of the Voting  Agreement
by Parent to the Stockholders.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

         Item 5 is hereby amended by adding the following thereto:

         By virtue of the Voting Agreement, the Reporting Persons may be deemed
to share dispositive power and voting power of the Company Common Stock held by
them with Parent and Merger Sub.

         The numbers of shares and  percentages  reported on the cover pages of
this Second  Amendment  have not been updated since  September 30, 2006 to give
effect to the accrual of additional  dividends on the Series C Preferred Stock,
the  numbers do reflect  the accrual of  additional  dividends  on the Series C
Preferred  Stock up through  September  30, 2006.  As dividends on the Series C
Preferred Stock accrue but are not paid, the actual number of shares of Company
Common  Stock into which the Series C Preferred  Stock is  convertible  and the
voting  power  of  the  Company  represented  by  such  shares,  will  increase
accordingly.

         Each of the Reporting Persons expressly disclaims beneficial ownership
of any  Company  Common  Stock held by any other  person to the extent that the
Reporting Person does not hold a pecuniary interest therein.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
         RESPECT TO SECURITIES OF THE ISSUER.

         The  responses  to Item 4 of this  Amendment  and the  Exhibit to this
Amendment are incorporated herein by this reference.
