6.    Escrow Agent.

(a)    The Escrow Agent shall have only the duties and responsibilities
specified in this Escrow Agreement, and shall not have any duty to review or
interpret the ASSA or the

 

8

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

EMEA ASA. The duties of the Escrow Agent hereunder are purely ministerial in
nature, and under no circumstances shall the Escrow Agent be deemed a fiduciary
to the Purchaser, the Sellers, nor to any other party under this Escrow
Agreement.

(b)    If the Escrow Agent shall be uncertain as to its duties or rights
hereunder or shall receive instructions from any of the undersigned with respect
to the Escrow Accounts, which, in its opinion, are in conflict with any of the
provisions of this Escrow Agreement, it shall be entitled to refrain from taking
any action until it shall be directed otherwise in joint written instructions
signed by Purchaser and the Seller Parties or by a Final Court Order. The Escrow
Agent shall be protected in acting upon any notice, request, waiver, consent,
receipt or other document reasonably believed by the Escrow Agent to be signed
by the proper party or parties.

(c)    The Escrow Agent shall not be liable for any error or judgment or for any
act done or step taken or omitted by it or for any mistake of fact or law, or
for anything that it may do or refrain from doing in connection herewith, except
its own gross negligence or willful misconduct, and the Escrow Agent shall have
no duties to anyone except those parties signing this Escrow Agreement. In no
event shall the Escrow Agent be liable for special, indirect, punitive or
consequential loss or damage of any kind whatsoever (including without
limitation lost profits), even if it has been advised of the possibility of such
loss or damage and regardless of the form of action.

(d)    The Escrow Agent may consult legal counsel in the event of any dispute or
question as to the construction of this Escrow Agreement, or the Escrow Agent’s
duties hereunder, and the Escrow Agent shall incur no liability and shall be
fully protected with respect to any action taken or omitted in good faith in
accordance with the opinion and instructions of such counsel.

(e)    In the event of any disagreement between the undersigned or any of them,
and/or any other person, resulting in adverse claims and demands being made in
connection with or for all or any portion of the Escrow Funds, the Escrow Agent
shall be entitled at its option to refuse to comply with any such claim or
demand, so long as such disagreement shall continue, and in so doing the Escrow
Agent shall not be or become liable for damages or interest to the undersigned
or any of them or to any person named herein for its failure or refusal to
comply with such conflicting or adverse demands. The Escrow Agent shall be
entitled to continue to so refrain and refuse to so act until all differences
with respect thereto shall have been resolved by agreement of Purchaser and the
Seller Parties and the Escrow Agent shall have been notified thereof in joint
written instructions signed by Purchaser and the Seller Parties. In the event of
such disagreement which continues for ninety (90) days or more, the Escrow Agent
in its discretion may file a suit in interpleader for the purpose of having the
respective rights of the claimants adjudicated, and may deposit with the court
all documents and property held hereunder. Purchaser and the Seller Parties
agree to pay all

 

9

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

reasonable out-of-pocket costs and expenses incurred by the Escrow Agent in such
action, including reasonable attorney’s fees, it being understood that the
parties will use reasonable efforts to cause such costs and expenses to be
included and apportioned between Purchaser and the Seller Parties in the
judgment in any such action (and absent such apportionment, Purchaser and the
Seller Parties shall bear equal shares of such costs and expenses).

(f)    Purchaser, NNL and NNI hereby jointly and severally indemnify, defend and
hold the Escrow Agent harmless from all loss, liability or expense arising out
of or in connection with (i) the Escrow Agent’s execution and performance of
this Escrow Agreement, except to the extent that such loss, liability or expense
is due to the gross negligence or willful misconduct of the Escrow Agent,
(ii) the Escrow Agent’s reliance upon and compliance with instructions or
directions, except to the extent that such loss, liability or expense is due to
the gross negligence or willful misconduct of the Escrow Agent, it being
understood that the failure of the Escrow Agent to verify or confirm that the
person giving the instructions or directions, is, in fact, an authorized person
does not constitute gross negligence or willful misconduct and (iii) the Escrow
Agent’s following any instructions or other directions from Purchaser or the
Seller Parties. As between the Purchaser, NNL and NNI, such indemnification
shall be borne 50% by the Purchaser and 50% by NNL and NNI and shall survive
termination of this Escrow Agreement until extinguished by any applicable
statute of limitations. Notwithstanding the foregoing, nothing in this
Section 6(f) shall be construed as creating an indemnification obligation of
NNUK in favor of the Escrow Agent.

(g)    The Escrow Agent does not own or have any interest in the Escrow Accounts
or the Escrow Funds but is serving as escrow holder only, having only possession
thereof and agreeing to hold and distribute the Escrow Funds in accordance with
the terms and conditions of this Escrow Agreement. This paragraph shall survive
notwithstanding any termination of this Escrow Agreement or the resignation of
the Escrow Agent.

(h)    The Escrow Agent (and any successor escrow agent) may at any time resign
as such by delivering the Escrow Funds to (i) any banking corporation or trust
company organized under the laws of the United States or of any state, which
corporation or company is jointly designated by the other parties hereto in
writing as successor escrow agent and consents in writing to act as successor
escrow agent or (ii) any court of competent jurisdiction; whereupon the Escrow
Agent shall be discharged of and from any and all further obligations arising in
connection with this Escrow Agreement. The resignation of the Escrow Agent will
take effect on the earlier of (x) the appointment of a successor escrow agent by
designation by the Purchaser and the Seller Parties and delivery of the Escrow
Funds to such successor escrow agent (or delivery of the Escrow Funds to any
court of competent jurisdiction) or (y) the day that is sixty (60) days after
the date of delivery of its written notice of resignation to the Purchaser and
the Seller Parties. If at the time of effectiveness of resignation the Escrow
Agent has not received a designation of a successor

 

10

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

escrow agent, the Escrow Agent’s sole responsibility after that time shall be to
safekeep the Escrow Funds until the earlier of receipt of a designation by the
other parties hereto of a successor escrow agent, a joint written instruction as
to disposition of the Escrow Funds by the other parties hereto, or a final order
of a court of competent jurisdiction mandating disposition of the Escrow Funds.

(i)    The Escrow Agent hereby accepts its appointment and agrees to act as
escrow agent under the terms and conditions of this Escrow Agreement. Purchaser
and the Seller Parties shall pay to the Escrow Agent as payment in full for its
services hereunder the Escrow Agent’s compensation set forth in Schedule II
hereto. Purchaser and the Seller Parties further agree to reimburse the Escrow
Agent for all reasonable out-of-pocket expenses, disbursements and advances
incurred or made by the Escrow Agent in the performance of its duties hereunder
(including reasonable fees and out-of-pocket expenses and disbursements of its
counsel). Purchaser, on the one hand, and the Seller Parties, on the other hand,
shall each pay one half of the amounts required to be paid under this
Section 6(i); provided, however, that the Seller Parties’ share of any such
costs and expenses shall be paid first from the Delay Fee Escrow Fund, then the
Holdback Escrow Fund, then the Good Faith Deposit Escrow Fund, and the Escrow
Agent may withdraw such one-half share from such Delay Fee Escrow Account,
Holdback Escrow Account or Good Faith Deposit Escrow Account when due, and as
applicable, provided that the Escrow Agent gives the Seller Parties and the
Purchaser reasonably prompt notice following each such withdrawal.

(j)    The Escrow Agent shall not incur any liability for not performing any act
or fulfilling any duty, obligation or responsibility hereunder by reason of any
occurrence beyond the control of the Escrow Agent (including but not limited to
any act or provision of any present or future law or regulation or governmental
authority, any act of God, war, earthquakes, fires, floods, wars, civil or
military disturbances, sabotage, acts of terrorism, epidemics, riots, loss or
malfunctions of utilities or communications service, labor disputes, acts of
civil or military authority or governmental actions); it being understood that
the Escrow Agent shall use commercially reasonable efforts which are consistent
with accepted practices in the banking industry to resume performance as soon as
practicable under the circumstances.

(k)    Concurrently with the execution of this Escrow Agreement, the Purchaser
and the Seller Parties shall deliver to the Escrow Agent authorized signers’
lists in the form of Exhibit B-1, Exhibit B-2, Exhibit B-3 and Exhibit B-4 to
this Escrow Agreement.

7.    Exclusion of Liability and Acknowledgments regarding Joint Administrators.

(a)    The Parties agree that the Joint Administrators have negotiated and are
entering into this Agreement as agents for NNUK to which they are appointed and
that none of the Joint Administrators, their firm, partners, employees,
advisers, representatives or agents shall

 

11

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

incur any personal Liability whatsoever whether on their own part or in respect
of any failure on the part of any other Party to observe, perform or comply with
any of its obligations under this Agreement or under or in relation to any
associated arrangements or negotiations.

(b)    Notwithstanding anything in Sections 16 or 17, any claim, action or
proceeding against the Joint Administrators arising from or related to (i) the
personal Liability of the Joint Administrators, their firm or partners,
(ii) their qualification to act as insolvency practitioners in accordance with
Part XIII of the Insolvency Act or (iii) their appointment as joint
administrators of NNUK and their remaining as current joint administrators
thereof under this Agreement shall be governed exclusively by English law and
subject to the exclusive jurisdiction of the English Courts.

(or to such other addresses and facsimile numbers as a party may designate as to
itself by notice to the other parties given pursuant to this Section 8).
Notwithstanding any of the foregoing, any computation of a time period which is
to begin after receipt of a notice by the Escrow Agent shall run from the date
of receipt by it.

9.    Termination. This Escrow Agreement shall automatically terminate upon the
final distribution of the Escrow Funds in accordance with the terms hereof;
provided, however, that the provisions of Sections 5(c), 6(f) and 6(g) shall
survive such termination of this Escrow Agreement and/or the resignation or
removal of the Escrow Agent.

10.    Successors and Assigns. This Escrow Agreement shall be binding upon and
inure to the benefit of the respective successors and permitted assigns of the
parties hereto, provided that this Escrow Agreement may not be assigned by any
party without the prior written consent of the other parties, which consent
shall not be unreasonably withheld. Notwithstanding the foregoing, the following
assignments shall not require consent of any party: (a) assignment of this
Escrow Agreement by the Purchaser to its lenders which, under certain
circumstances, would permit such lenders to enforce this Escrow Agreement on
behalf of Purchaser, (b) assignment of this Escrow Agreement by the Purchaser to
any entity which acquires substantially all of the assets of Purchaser and
agrees to be bound hereto as successor to Purchaser, (c) assignment by a Seller
that is a U.S. Debtor to an entity that is the surviving, resulting or acquiring
entity of, and successor to, such U.S. Debtor pursuant to a final court order
confirming a chapter 11 plan of reorganization for such U.S. Debtor and
(d) assignment by any Seller that is a Canadian Debtor pursuant to any plan of
arrangement approved by the Canadian Court. Any banking association or
corporation into which the Escrow Agent may be merged, converted or with which
the Escrow Agent may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Escrow Agent shall be a party,
or any banking association or corporation to which all or substantially all of
the corporate trust business of the Escrow Agent shall be sold or otherwise
transferred, shall succeed to all the Escrow Agent’s rights, obligations and
immunities hereunder without the execution or filing of any instrument or any
further act, any provision herein to the contrary notwithstanding.

11.    Severability. Any term or provision of this Escrow Agreement that is
invalid or unenforceable in any situation in any jurisdiction will not affect
the validity or enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction. In the event that any provision hereof
would, under applicable law, be invalid or unenforceable in any respect, each
party hereto

 

15

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

intends that such provision will be construed by modifying or limiting it so as
to be valid and enforceable to the maximum extent compatible with, and possible
under, applicable law.

12.    Entire Agreement. This Escrow Agreement (together with any documents,
instruments and certificates explicitly referred to herein, including the ASSA
and EMEA ASA, as they pertain to the Purchaser and the Seller Parties only)
constitutes the entire agreement among the parties hereto with respect to the
subject matter hereof and supersedes any and all prior discussions,
negotiations, proposals, undertakings, understandings and agreements, whether
written or oral, with respect thereto.

13.    Amendments. This Escrow Agreement may not be amended or modified at any
time except in such manner as may be agreed upon by a written instrument
executed by each of Purchaser, the Seller Parties and the Escrow Agent.

14.    Waiver. No waiver of any provision hereof shall be effective unless made
in writing and signed by the waiving party. The failure of any party to require
the performance of any term or obligation of this Escrow Agreement, or the
waiver by any party of any breach of this Escrow Agreement, shall not prevent
any subsequent enforcement of such term or obligation or be deemed a waiver of
any subsequent breach.

15.    Headings. The headings contained in this Escrow Agreement are for
convenience purposes only and will not in any way affect the meaning or
interpretation hereof.

16.    Governing Law. This Escrow Agreement, the rights of the parties and any
questions, claims, disputes, remedies or actions arising from or related to this
Escrow Agreement, and any relief or remedies sought by any parties, shall be
governed exclusively by the Laws of the State of New York applicable to
contracts made and to be performed in that State and without regard to the rules
of conflict of laws of the State of New York or any other jurisdiction.

17.    Consent to Jurisdiction; Venue.

(a)    To the fullest extent permitted by applicable Law, the Purchaser and the
Seller Parties each: (i) agrees that any claim, action, proceeding by such party
seeking any relief whatsoever arising out of, or in connection with, this Escrow

closing the Chapter 11 Cases, or the Canadian Court, if brought prior to the
termination of the CCAA Cases, provided that if (x) a final decree closing the
Chapter 11 Cases has not been entered and (y) the CCAA Cases have not
terminated, the U.S. Debtors, the Canadian Debtors or the Purchaser may, in
accordance with the Cross-Border Protocol, move the U.S. Bankruptcy Court and
the Canadian Court to hold a joint hearing of the U.S. Bankruptcy Court and the
Canadian Court to determine the appropriate jurisdiction for such claim, action
or proceeding, or (B) in the Federal Courts in the Southern

 

16

and shall not be brought in each case, in any other court in the United States
of America, Canada or any court in any other country; (ii) agrees to submit to
the jurisdiction of the Designated Courts for purposes of all legal proceedings
arising out of, or in connection with, this Escrow Agreement or the transactions
contemplated hereby; (iii) waives and agrees not to assert any objection that it
may now or hereafter have to the laying of the venue of such action brought in
any Designated Court or any claim that any such action brought in any Designated
Court has been brought in an inconvenient forum; (iv) agrees that the mailing of
process or other papers in connection with any such action or proceeding in the
manner provided in Section 8 of this Escrow Agreement or any other manner as may
be permitted by Law shall be valid and sufficient service thereof, and
(v) agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by applicable law.

(b)    The Purchaser hereby appoints McCarthy Tétrault LLP – Attention: Kevin
McElcheran, as its authorized agent (the “Purchaser Authorized Canadian Agent”)
upon whom process and any other documents may be served in the CCAA Cases and
any Action arising out of, or in connection with, this Escrow Agreement or the
transactions contemplated hereby, which may be instituted in the Canadian Court
by any other party hereto, which appointment in each case shall be irrevocable.
The Purchaser further agrees to take any and all action, including the filing of
any and all documents and instruments, which may be necessary to continue such
appointments in full force and effect as aforesaid. Service of process upon the
Purchaser Authorized Canadian Agent in respect of the relevant jurisdiction and
written notice of such service to the Purchaser shall be deemed, in every
respect, effective service of process upon the Purchaser in relation to such
jurisdiction.

(c)    Each Seller Party hereby appoints (i) NNI as its authorized agent (the
“Seller Authorized U.S. Agent”) upon whom process and any other documents may be
served in the Chapter 11 Cases and any Action arising out of, or in connection
with, this Escrow Agreement or the transactions contemplated hereby, which may
be instituted in the U.S. Bankruptcy Court or in the NY Courts by any other
party hereto, and (ii) NNL as its authorized agent (the “Seller Authorized
Canadian Agent” and together with the Seller Authorized U.S. Agent, the “Seller
Authorized Agents”) upon whom process and any other documents may be served in
the CCAA Cases and any Action arising out of, or in connection with, this Escrow
Agreement or the transactions contemplated hereby, which may be instituted in
the Canadian Court by any other party hereto, which appointment in each case
shall be irrevocable. Each such Seller further agrees to take any and all
action, including the filing of any and all documents and instruments, which may
be necessary to continue such

 

17

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

appointment in full force and effect as aforesaid. Service of process upon the
applicable Seller Authorized Agent in respect of the relevant jurisdiction and
written notice of such service to NNL and NNI shall be deemed, in every respect,
effective service of process upon every such Seller.

(d)    Waiver of Jury Trial. EACH PARTY HEREBY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT
OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION
WITH THIS ESCROW AGREEMENT, ANY ANCILLARY AGREEMENT OR ANY TRANSACTION
CONTEMPLATED HEREBY OR THEREBY. EACH PARTY (I) CERTIFIES THAT NO REPRESENTATIVE,
AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE,
THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
FOREGOING WAIVER AND (II) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE
BEEN INDUCED TO ENTER INTO THIS ESCROW AGREEMENT AND THE ANCILLARY AGREEMENTS,
AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN
THIS SECTION.

18.    Counterparts. This Escrow Agreement may be executed in any number of
counterparts, each of which will be deemed an original, but all of which
together will constitute one and the same instrument. This Escrow Agreement will
become effective when duly executed by each party hereto.

19.    No Presumption. The parties agree that this Escrow Agreement was
negotiated fairly between them at arm’s length and that the final terms of this
Escrow Agreement are the product of the parties’ negotiations. Each party
represents and warrants that it has sought and received experienced legal
counsel of its own choosing with regard to the contents of this Escrow Agreement
and the rights and obligations affected hereby. The parties agree that this
Escrow Agreement shall be deemed to have been jointly and equally drafted by
them, and that the provisions of this Escrow Agreement therefore should not be
construed against a party on the grounds that such party drafted or was more
responsible for drafting the provisions.

For Cash Balances

Direction to use Wells Fargo Advantage Funds for Cash Balances for the escrow
account or accounts (the “Account”) established under the Escrow Agreement to

In the absence of written investment instructions, the Escrow Agent is hereby

time to time, all cash in the Account in the following money market portfolio of
Wells Fargo Advantage Funds (the “Fund”) or another permitted investment of

Purchaser acknowledges that it has received, at its request, and reviewed the
Fund’s prospectus and has determined that the Fund is an appropriate investment
for the Account.

Purchaser understands from reading the Fund’s prospectus that Wells Fargo Funds

Wells Fargo & Company, provides investment advisory and other administrative
services for the Wells Fargo Advantage Funds. Other affiliates of Wells Fargo &
Company provide sub-advisory and other services for the Funds. Boston Financial

by Wells Fargo Funds Distributor, LLC, Member NASD/SIPC, an affiliate of Wells
Fargo & Company. Purchaser also understands that Wells Fargo & Company will be
paid, and its bank affiliates may be paid, fees for services to the Funds and
that those fees may include Processing Organization fees as described in the
Fund’s prospectus.

Purchaser understands that the Escrow Agent will not exclude amounts invested in
the Fund from Account assets subject to fees under the Account agreement between
us.

Purchaser understands that investments in the Fund are not obligations of, or
endorsed or guaranteed by, Wells Fargo Bank or its affiliates and are not
insured by the Federal Deposit Insurance Corporation.

Purchaser acknowledges that it has full power to direct investments of the
Account.

Purchaser understands that it may change this direction at any time and that it
shall continue in effect until revoked or modified by Purchaser by written
