The parties hereto may change the address at which they are to receive notices
hereunder, by notice in writing in the foregoing manner given to the other.

(b) Buyer Acknowledgement; Release. Buyer acknowledges that it is experienced,
sophisticated and knowledgeable in the purchase and sale of securities of public
companies such as the Borrower and is capable of evaluating the merits and risks
of purchasing the Subordinated Loans and Subordinated Loan Documents and of
protecting its own interests in connection with such sale. Buyer acknowledges
that Pequot and its representatives may possess material information (“Excluded
Information”) regarding the Subordinated Loans and Subordinated Loan Documents,
the Borrower or its other outstanding securities that has not been provided to
Buyer, including, without limitation, information received on a confidential
basis directly or indirectly from the Borrower. Buyer acknowledges that it has
not requested and does not wish to receive Excluded Information from Pequot and
agrees that Pequot shall not have any liability to Buyer with respect to
non-disclosure of Excluded Information. Buyer acknowledges that the Excluded
Information may be indicative of a value of the Subordinated Loans and
Subordinated Loan Documents that is substantially less than the Purchase Price
reflected in the sale contemplated hereby or otherwise adverse to Buyer’s
interest, and, therefore, such Excluded Information might be material to Buyer’s
decision to purchase the Subordinated Loans and Subordinated Loan Documents.
Buyer understands that Martin Hale, a managing director of the investment
manager of Pequot, served on the Board of Directors of the Borrower as board
designee of Pequot. Buyer understands the potential disadvantage to which Buyer
is subject on account of a possible disparity of information as between Buyer
and Pequot. Buyer acknowledges that in entering into this Addendum and
purchasing the Subordinated Loans and Subordinated Loan Documents, it has not
relied on any representations made by Pequot (other than those specifically set
forth in Section 8(a) through 8(e)), nor has it relied on any obligation of
Pequot to disclose any information it may possess. Buyer acknowledges that
Pequot would not enter into this Addendum in the absence of the protections
afforded to Pequot by this paragraph and the specific statement of non-reliance
contained herein. Buyer hereby waives and releases and promises never to assert
any claims or causes of action, whether or not now known, against Pequot or its
predecessors, successors, or past or present subsidiaries, partners, officers,
directors, agents, employees and assigns, with respect to the Subordinated Loans
and Subordinated Loan Documents or Buyer’s purchase or ownership thereof (other
than with respect to a breach of representation, warranty or covenant by such
Pequot under this Addendum).

(c) No Waiver. No delay or omission by either party hereto in exercising any
right or power arising from any default by the other party hereto shall be
construed as a waiver of such default or as an acquiescence therein, nor shall
any single or partial exercise thereof preclude any further exercise thereof or
the exercise of any other right or power arising from any

 

6

--------------------------------------------------------------------------------

default by the other party hereto. No waiver of any breach of any of the
covenants or conditions contained in this Addendum shall be construed to be a
waiver of or an acquiescence in or a consent to any previous or subsequent
breach of the same or of any other condition or covenant.

(d) No Third Party Beneficiary. This Addendum is made for the sole benefit of
Pequot and Buyer and their respective successors and permitted assigns, and no
other person or persons shall have any rights or remedies under or by reason of
this Addendum or any right to the exercise of any right or power of either party
hereto or arising from any default by either party hereto.

(e) Attorney Fees and Costs. In the event any legal action is undertaken in
order to enforce or interpret any provision of this Addendum, the prevailing
party in such legal action, as determined by the court, shall be entitled to
receive from the other party the prevailing party’s reasonable attorneys’ fees
and court costs.

(f) Time of Essence. Time is hereby declared to be of the essence of this
Addendum and of every part hereof. When the context and construction so require,
all words used in the singular herein shall be deemed to have been used in the
plural and the masculine shall include the feminine and the neuter and vice
versa.

(g) No Assignment to Third Party. Prior to Closing, this Addendum shall not be
assigned by either party without the written consent of the other party, which
consent may be withheld in such other party’s sole discretion.

(h) Integration; Entire Agreement. This Addendum and any documents executed in
connection herewith or pursuant hereto constitute the entire understanding
between the parties hereto with respect to the subject matter hereof,
superseding all prior written or oral understandings, and may not be terminated,
modified or amended in any way except by a written agreement signed by each of
the parties hereto.

(i) Counterparts. This Addendum may be executed in two or more counterparts,
each of which shall be deemed an original but all of which together shall
constitute but one and the same document.

(j) No Continuing Liability. Buyer and Pequot hereby acknowledge, confirm and
agree that Buyer shall have no claims and Pequot shall have no liability
whatsoever as a result of or otherwise in connection with any loss of value,
notice of default, notice of sale or bankruptcy of Borrower under the
Subordinated Loans.

(k) Legal Effect. The Subordinated Loan Documents remain in full force and
effect. If any provision of this Addendum conflicts with applicable law, such
provision shall be deemed severed from this Addendum, and the balance of this
Addendum shall remain in full force and effect.

(l) Choice of Law and Venue; Jury Trial Waiver. This Addendum shall be governed
by, and construed in accordance with, the internal laws of the State of New
York, without regard to principles of conflicts of law. EACH OF THE PARTIES
HEREBY WAIVES ANY RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED
UPON

 

7

--------------------------------------------------------------------------------

OR ARISING OUT OF THIS ADDENDUM OR ANY TRANSACTION CONTEMPLATED HEREIN,
INCLUDING CLAIMS BASED ON CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER COMMON
LAW OR STATUTORY BASES. Each party hereby submits to the exclusive jurisdiction
of the state and federal courts located in the County of New York, State of New
York. If the jury waiver set forth in this Section is not enforceable, then any
dispute, controversy or claim arising out of or relating to this Addendum or any
of the transactions contemplated herein will be finally settled by binding
arbitration in New York, New York in accordance with the then-current Commercial
Arbitration Rules of the American Arbitration Association by one arbitrator
appointed in accordance with said rules. The arbitrator shall apply New York law
to the resolution of any dispute, without reference to rules of conflicts of law
or rules of statutory arbitration. Judgment on the award rendered by the
arbitrator may be entered in any court having jurisdiction thereof.
Notwithstanding the foregoing, the parties may apply to any court of competent
jurisdiction for preliminary or interim equitable relief, or to compel
arbitration in accordance with this paragraph. The expenses of the arbitration,
including the arbitrator’s fees and expert witness fees, incurred by the parties
to the arbitration, may be awarded to the prevailing party, in the discretion of
the arbitrator, or may be apportioned between the parties in any manner deemed
appropriate by the arbitrator. Unless and until the arbitrator decides that one
party is to pay for all (or a share) of such expenses, both parties shall share
equally in the payment of the arbitrator’s fees as and when billed by the
arbitrator.
