1. Definitions. Capitalized terms used herein without definition shall have the
respective meanings assigned to such terms in the Relationship Agreement.

2. Section 9.2(a) (Receiver Share Schemes). Clause (W) of the second sentence of
Section 9.2(a) of the Relationship Agreement is hereby deleted in its entirety
and replaced with the following:

“(W) 1.95% of the number of Fully-Diluted Shares outstanding at the close of
business on the Closing Date plus”

3. Section 9.2(d) (Receiver Share Schemes). Section 9.2 of the Relationship
Agreement is hereby amended by inserting the following as a new subsection
(d) to Section 9.2:

“(d)(1) Quarterback agrees that, in connection with a proposal by Receiver to
increase the number of shares available under the Receiver Share Schemes by up
to 10,000,000 shares, it shall (a) cause any and all shares of Receiver Common
Stock held by the Quarterback Group to be voted in favor of such proposal,
whether at an annual or special meeting of Receiver stockholders or otherwise,
and (b) take all other reasonable actions in furtherance thereof; provided
however that Quarterback’s obligations under this sub-clause (d) are conditional
upon the proposal falling within the scope of the resolution approved by the
shareholders of Quarterback at the extraordinary general meeting held in London
on December 9, 2008. (2) Quarterback shall not, and shall cause the Quarterback
Group to not, Transfer or agree to Transfer, directly or indirectly, any shares
of Receiver common stock to any Person or group (other than Receiver or another

holding less than 50.1% of Receiver common stock on a fully diluted basis,

unless prior to such Transfer, the transferee agrees in a writing addressed to
Receiver to assume and honor all of Quarterback’s obligations under this
Section 9.2(d). (3) Receiver agrees that, upon receipt of a written request from
Quarterback to do so, it shall as promptly as practicable put the proposal

Relationship Agreement as amended hereby.

(b) Except as specifically amended by this Amendment, the Relationship Agreement
shall remain in full force and effect and the Relationship Agreement, as amended
by this Amendment, is hereby ratified and confirmed in all respects. Upon the
execution and delivery hereof, the Relationship Agreement shall thereupon be
deemed to be amended as hereinabove set forth as fully and with the same effect
as if the amendment made hereby was originally set forth in the Relationship
Agreement, and this Amendment and the Relationship Agreement shall henceforth be
read, taken and construed as one and the same instrument, but such amendments
and supplements shall not operate so as to render invalid or improper any action
heretofore taken under the Relationship Agreement.
