On December 23, 2007,  JANA,  CT-100,  AIM,  Paul Gardi  ("Gardi")  and Velocity
entered  into an amended and  restated  agreement  (the  "Amended  and  Restated
Agreement").  Pursuant to the Amended and  Restated  Agreement,  AIM, as Gardi's
employer,  and Gardi agreed to provide  financial and  operational  advisory and
consulting  services to JANA and CT-100 in connection with existing or potential
investments by JANA and CT-100 (and affiliated  entities of both) in Shares.  In
return, Gardi is entitled to receive compensation consisting of (i) a consulting
fee (the  "Consulting  Fee") equal to four quarterly  payments of $25,000 (which
Consulting  Fee shall be  refunded  to the extent  Gardi  receives  any  payment
directly from the Issuer or in respect of the Profit  Participation  (as defined
below)) and (ii) 9% of the net profits of JANA,  CT-100 and affiliated  entities
of both from  investments  in Shares (the  "Profit  Participation").  The Profit
Participation  is payable  to Gardi  only if the net  profits of JANA and CT-100
(and  affiliated  entities of both) on their  investment  in Shares exceed an 8%
internal rate of return. The Profit Participation will be paid to Gardi upon the
realization of such net profits, or, if Shares to which the Profit Participation
applies  remain  unsold on December 23,  2010,  upon the request of Gardi at any
time  thereafter.  Consulting fees or other  compensation  paid to any potential
third party nominee to the Board will be deducted from the amount paid to Gardi,
subject to certain  caps,  in  respect  of the Profit  Participation.  Under the
Amended and  Restated  Agreement,  CT-100 and Gardi have agreed to purchase  $20
million and $1 million,  respectively,  of Shares from JANA. Gardi's purchase of
Shares  under  the  Amended  and  Restated  Agreement  will be  made by AIM,  as
contemplated by the Amended and Restated Agreement, and it is expected that such
Shares will be purchased through a capital contribution by AIM (i) to a Delaware
limited  liability  company to be  organized  by JANA to hold  Shares (the "JANA
SPV") and (ii) to  CT-100.  Each  purchaser  of Shares  under  the  Amended  and
Restated  Agreement  further  agreed not to sell such  Shares (or in the case of
Velocity,  any Shares acquired under the Option Agreement) until the earliest of
(i) the  disposition  of all Shares owned by JANA  (provided  that if JANA sells
less  than  all  of  the  Shares  owned  by  it,  CT-100,  Gardi  and  Velocity,
respectively, may sell a pro rata portion of any Shares owned by them), (ii) the
commencement of the Issuer's next annual meeting of shareholders,  and (iii) the
date that  JANA  notifies  any  other  party  that it has  ceased to pursue  any
proposals to the Issuer regarding the conduct of its business. In addition,  the
Amended and Restated Agreement  provides that all public statements,  regulatory
filings,  contacts with management and related  activities related to the Issuer
will be made and  conducted  by JANA,  following  reasonable  consultation  with
CT-100, AIM and, should it acquire Shares,  Velocity,  and further provides that
the Profit  Participation and all reasonable third party expenses related to any
proxy  contest  shall be shared by JANA,  CT-100 and  should it acquire  Shares,
Velocity, pro rata to their investment in Shares. In addition, JANA and Velocity
have  entered  into an Option  Agreement,  dated  December 21, 2007 (the "Option
Agreement")  giving  Velocity  the option to purchase  from JANA up to 1,000,000
Shares at $10.00 per Share for six months beginning December 21, 2007.

Pursuant to an Agreement, dated January 4, 2008 (the "Sandell Group Agreement"),
between JANA and  Sandell,  Sandell  agreed not to sell any Shares  purchased by
funds,  accounts  or other  affiliated  entities  ("Sandell  Funds")  until  the
earliest of (i) the  disposition  of all Shares owned by JANA  (provided that if
JANA sells less than all of the Shares owned by it, Sandell Funds may sell a pro
rata portion of any Shares owned by them), (ii) the commencement of the Issuer's
next  annual  meeting  of  shareholders  and (iii)  the date that JANA  notifies
Sandell that it has ceased to






pursue any proposals to the Issuer  regarding  the conduct of its  business.  In
addition,  the Sandell  Group  Agreement  provides  that all public  statements,
regulatory  filings,  contacts with management and related activities related to
the Issuer will be made and conducted by JANA, following reasonable consultation
with Sandell and the parties to the Amended and Restated Agreement,  and further
provides  that Sandell  shall  reimburse the parties to the Amended and Restated
Agreement  for its pro rata share of (i) the Profit  Participation  and (ii) all
reasonable third party expenses related to any proxy contest.

The  foregoing  description  of the Amended and Restated  Agreement,  the Option
Agreement and the Sandell Group Agreement is a summary only.

By virtue of the Amended and Restated  Agreement,  the Option  Agreement and the
Sandell Group Agreement, JANA, Spark, Velocity, AIM and Sandell may be deemed to
have  formed a "Group"  within  the  meaning  of  Section  13(d)(3)  of the Act.
However,  each of JANA, Spark,  Velocity,  AIM and Sandell  expressly  disclaims
beneficial  ownership of any Shares  beneficially  owned by the other members of
the group.  Neither the fact of this filing nor anything  contained herein shall
be deemed to be an admission  by any of such  parties that it is the  beneficial
owner of any Shares  beneficially  owned by any of the other parties,  except as
otherwise disclosed herein.

Each of the Nominees has entered into a nominee agreement  pursuant to which the
JANA and CT-100 have agreed to pay the costs of soliciting proxies in connection
with the  Issuer's  2008  annual  meeting  of  shareholders,  and to defend  and
indemnify  the  Nominees  against,  and with  respect to, any losses that may be
incurred by them in the event they become a party to  litigation  based on their
nomination  as  candidates  for election to the board of directors of the Issuer
and the solicitation of proxies in support of their election.  In addition,  the
nominee  agreements with Mr. Miller,  Mr.  Genachowski,  Ms.  Studenmund and Mr.
Weinstein   provide  that  they  are  entitled  to  receive  certain   specified
compensation  in the  event  that they are  elected  or  appointed  and serve as
directors  of the  Issuer,  and in the event they serve as a nominee but are not
elected or appointed.  Mr.  Gardi,  Mr. Politi and Mr. Caputo do not receive any
compensation   under  their  nominee   agreements   and  will  not  receive  any
compensation from JANA, Spark,  Velocity or AIM or such parties'  affiliates for
their services as directors of the Issuer if elected.  If elected,  the Nominees
will be entitled to such  compensation from the Issuer as is consistent with the
Issuer's past practices for services of non-employee directors.

In addition to the above, partners or employees of JANA, Spark, Velocity, AIM,
Sandell and the Nominees may assist in the solicitation of proxies and will
receive no additional consideration therefore.
