attorneys, accountants and controlling persons (each, an “Indemnified Party”) to the fullest
extent permitted by law from and against any and all losses, claims, damages, expenses
(including, without limitation, reasonable fees, disbursements and other charges of counsel
and costs of investigation incurred by an Indemnified Party in any action or proceeding
between such Indemnified Party or Indemnified Parties and any third party or otherwise) or
other liabilities, losses, or diminution in value (collectively, “Liabilities”) resulting
from or arising out of any legal, administrative or other actions (including, without
limitation, actions brought by any holders of equity or indebtedness of the Company or
derivative actions brought by any Person claiming through or in the name of the Company),
proceedings or investigations (whether formal or informal), or written threats thereof,
based upon, relating to or arising out of the Investment Documents, or any Indemnified
Party’s role therein; provided, however, that neither the Company nor any of
its Subsidiaries shall be liable under this Section 10.1 to an Indemnified Party to the
extent that it is finally judicially determined that such Liabilities resulted primarily
from the willful misconduct or gross negligence of such Indemnified Party; provided,
further, that if and to the extent that such indemnification is unenforceable for
any reason, the Company shall, and shall cause its Subsidiaries to, make the maximum
contribution to the payment and satisfaction of such Liabilities that shall be permissible
under applicable Law. In connection with the obligation of the Company to indemnify for
expenses as set forth above, the Company further agrees, upon presentation of appropriate
invoices containing reasonable detail, to reimburse, or cause its Subsidiaries to reimburse,
without duplication, each Indemnified Party for all such expenses (including, without
limitation, fees, disbursements and other charges of counsel and costs of investigation
incurred by an Indemnified Party in any action or proceeding between an Indemnified Party
(or Indemnified Parties) and any third party) as they are incurred by such Indemnified
Party; provided, however, that if an Indemnified Party is reimbursed
hereunder for any expenses, such reimbursement of expenses shall be refunded to the extent
it is finally judicially determined that the Liabilities in question resulted primarily from
the willful misconduct or gross negligence of such Indemnified Party.

Section 10.2 Procedure; Notification. Each Indemnified Party under this
Article X shall, promptly after the receipt of written notice of the commencement of any
action, investigation, claim or other proceeding against such Indemnified Party in respect
of which indemnity may be sought from the Company under this Article X, notify the Company
in writing of the commencement thereof. The omission of any Indemnified Party so to notify
the Company of any such action shall not relieve the Company from any liability which it may
have to such Indemnified Party unless, and only to the extent that, such omission results in
the Company being materially prejudiced thereby. In case any such action, claim or other
proceeding shall be brought against any Indemnified Party and it shall notify the Company of
the commencement thereof, the Company shall be entitled to assume, or cause its Subsidiaries
to assume, the defense thereof at its or their own expense, with counsel satisfactory to
such Indemnified Party in its reasonable judgment; provided, however, that
any Indemnified Party may, at its own expense, retain separate counsel to participate in
such defense. Notwithstanding the foregoing, in any action, claim or proceeding in which
the Company, on the one hand, and an Indemnified Party, on the other hand, is, or is
reasonably likely to become, a party, such Indemnified Party shall have the right to employ
separate counsel at the expense of the Company and to control its own defense of such
action, claim or proceeding if, in the reasonable opinion of counsel to such Indemnified
Party, a conflict or potential conflict exists between the Company, on the one hand, and
such Indemnified Party, on the other hand, that would make such separate representation
advisable; provided, however, that in no event shall the Company be required
to pay fees and expenses under this Article X for more than one firm of attorneys (plus
local counsel) in any jurisdiction in any one legal action or group of related legal
actions. The Company agrees that it will not, without the prior written consent of the
Holders, settle, compromise or consent to the entry of any judgment in any pending or
threatened claim, action or proceeding relating to the matters contemplated hereby (if any
Indemnified Party is a party thereto or has been actually threatened to be made a party
thereto) unless such settlement, compromise or consent includes an unconditional release of
such Indemnified Party from all liability arising or that may arise out of such claim,
action or proceeding. The Company shall not be liable for any settlement of any claim,
action or proceeding effected against an Indemnified Party without its written consent,
which consent shall not be unreasonably withheld, delayed or conditioned. The rights
accorded to the Indemnified Parties hereunder shall be in addition to any rights that any
Indemnified Party may have at common law, by separate agreement or otherwise.

ARTICLE XI.

Section 11.1 Redemption at the Option of the Company. The Company may, at any

together, with respect to the Notes being redeemed, with all interest accrued pursuant to
the terms of the Notes and unpaid (including default interest to the extent applicable) as
of the date of such payment and all reasonable out-of-pocket costs and expenses (including,
without limitation, reasonable fees, charges and disbursements of counsel), if any, incurred
by the Holders and associated with such payment; provided, however, that in the event that
the Company redeems a portion and not all of the principal amount of the outstanding Notes,
the Company shall redeem (a) not less than $250,000 in principal amount of the outstanding
Notes or (b) in the event that less than $250,000 in principal amount of the Notes remains

at least five (5) days and not more than ten (10) days prior to the date fixed for such
redemption. Such notice of redemption shall be delivered in the manner specified in Section

covenants and agrees that it will redeem the Notes, on the date specified in such notice, at

5. Secured Parties’ Rights Re Collateral. At any time (whether or not an Event of
Default has occurred), without notice or demand and at the expense of Grantors, the Secured Parties
may, to the extent it may be necessary or desirable to protect the security hereunder, but the
Secured Parties shall not be obligated to: (a) enter upon any premises on which Collateral is
situated upon reasonable notice and examine the same or (b) upon the occurrence of and during the
continuation of an Event of Default, perform any obligation under this Agreement or any obligation
of any other Person under the Note Purchase Agreement. Each Grantor shall maintain books and
records pertaining to the Collateral in such detail, form and scope as is consistent with industry
practices. The Secured Parties shall at all times on reasonable notice have full access to and the
right to audit any and all of Grantors’ books and records pertaining to the Collateral, and to
confirm and verify the value of the Collateral and to do whatever else the Secured Parties
reasonably may deem necessary or desirable to protect their interests. The Secured Parties shall
be under no duty or obligation whatsoever to take any action to preserve any rights of or against
any prior or other parties in connection with the Collateral, to exercise any voting rights or
managerial rights with respect to any Collateral, whether or not an Event of Default shall have
occurred, or to make or give any presentments, demands for performance, notices of non performance,
protests, notices of protests, notices of dishonor or notices of any other nature whatsoever in
connection with the Collateral or the Secured Obligations. The Secured Parties shall be under no
duty or obligation whatsoever to take any action to protect or preserve the Collateral or any
rights of a Grantor therein, or to make collections or enforce payment thereon, or to participate
in any foreclosure or other proceeding in connection therewith.

6. Possession of Collateral by the Secured Parties. All the Collateral now,
heretofore or hereafter delivered to the Secured Parties shall be held by the Secured Parties in
their possession, custody and control. Nothing herein shall obligate the Secured Parties to invest
any Collateral or obtain any particular return thereon. Upon the occurrence and during the
continuance of an Event of Default, whenever any of the Collateral is in the Secured Parties’
possession, custody or control, the Secured Parties may use, operate and consume the Collateral,
whether for the purpose of preserving and/or protecting the Collateral, or for the purpose of
performing any of a Grantor’s obligations with respect thereto, or otherwise. The Secured Parties
may at any time deliver or redeliver the Collateral or any part thereof to a Grantor, and the
receipt of any of the same by such Grantor shall be complete and full acquittance for the
Collateral so delivered, and the Secured Parties thereafter shall be discharged from any liability
or responsibility therefor. So long as the Secured Parties exercise reasonable care with respect
to any Collateral in its possession, custody or control, the Secured Parties shall have no
liability for any loss of or damage to such Collateral, and in no event shall the Secured Parties
have liability for any diminution in value of Collateral occasioned by economic or market
conditions or events. The Secured Parties shall be deemed to have exercised reasonable care within
the meaning of the preceding sentence if the Collateral in the possession, custody or control of
the Secured Parties is accorded treatment substantially equal to that which the Secured Parties
accords their own property, it being understood that the Secured Parties shall not have any
responsibility for (a) ascertaining or taking action with respect to calls, conversions, exchanges,
maturities, tenders or other matters relating to any Collateral, whether or not the Secured Parties
have or are deemed to have knowledge of such matters, or (b) taking any necessary steps to preserve
rights against any Person with respect to any Collateral.

7. Rights Upon Event of Default. Upon the occurrence and during the continuance of an
Event of Default, the Secured Parties shall have, in any jurisdiction where enforcement hereof is
sought, in addition to all other rights and remedies that the Secured Parties may have under
applicable law or in equity or under this Agreement or under the Note Purchase Agreement, all
rights and remedies of a secured party under the New York Commercial Code as enacted in any
jurisdiction, and, in addition, the following rights and remedies, all of which may be exercised
with or without notice to the Grantors (except as expressly provided herein) and without affecting
the Obligations of FPI hereunder or under the Note Purchase Agreement, or the enforceability of the
Liens and security interests created hereby: (a) to foreclose the Liens and security interests
created hereunder or under any other agreement relating to any Collateral by any available judicial
procedure or without judicial process; (b) to enter any premises where any Collateral may be
located for the purpose of securing, protecting, inventorying, appraising, inspecting, repairing,
preserving, storing, preparing, processing, taking possession of or removing the same; (c) to sell,
assign, lease or otherwise dispose of any Collateral or any part thereof, either at public or
private sale or at any broker’s board, in lot or in bulk, for cash, on credit or otherwise, with or
without representations or warranties and upon such terms as shall be acceptable to the Secured
Parties; (d) to notify obligors on the Collateral that the Collateral has been assigned to the
Secured Parties and that all payments thereon are to be made directly and exclusively to the
Secured Parties; (e) to enter into any extension, reorganization, deposit, merger or consolidation
agreement, or any other agreement relating to or affecting the Collateral, and in connection
therewith the Secured Parties may deposit or surrender control of the Collateral and/or accept
other property in exchange for the Collateral; (f) to settle, compromise or release, on terms
acceptable to the Secured Parties, in whole or in part, any amounts owing on the Collateral and/or
any disputes with respect thereto; (g) to extend the time of payment, make allowances and
adjustments and issue credits in connection with the Collateral in the name of the Secured Parties
or in the name of Grantors; (h) to enforce payment and prosecute any action or proceeding with
respect to any or all of the Collateral and take or bring, in the name of the Secured Parties or in
the name of a Grantor, any and all steps, actions, suits or proceedings deemed by the Secured
Parties necessary or desirable to effect collection of or to realize upon the Collateral,
including, without limitation, any judicial or nonjudicial foreclosure thereof or thereon,
and each Grantor specifically consents to any nonjudicial foreclosure of any or all of the
Collateral or any other action taken by the Secured Parties which may release any obligor from
personal liability on any of the Collateral, and to the extent permitted by applicable law, each
Grantor waives any right not expressly provided for in this Agreement to receive notice of any
public or private judicial or nonjudicial sale or foreclosure of any security or any of the
Collateral; and any money or other property received by the Secured Parties in exchange for or on
account of the Collateral, whether representing collections or proceeds of Collateral, and whether
resulting from voluntary payments or foreclosure proceedings or other legal action taken by the
Secured Parties or a Grantor may be applied by the Secured Parties without notice to Grantors to
the Secured Obligations in such order and manner as the Secured Parties in their sole discretion
shall determine; (i) to insure, process and preserve the Collateral; (j) to exercise all rights,
remedies, powers or privileges provided under the Note Purchase Agreement; (k) to receive, open and
dispose of all mail addressed to Company and notify postal authorities to change the address for
delivery thereof to such address as the Secured Parties may designate; provided that the
Secured Parties agree that they will promptly deliver over to Grantors such mail as does not relate
to the Collateral; and (l) to exercise all other rights, powers, privileges and remedies of an
owner of the Collateral; all at the Secured Parties’ sole option and as the Secured Parties in
their sole discretion may deem advisable. Grantors will, at the Secured Parties’ request, assemble
the Collateral and make it available to the Secured Parties at places which the Secured Parties may
designate, whether at the premises of Company or elsewhere, and will make available to the Secured
Parties, free of cost, all premises, equipment and facilities of Grantors for the purpose of the
Secured Parties’ taking possession of the Collateral or storing same or removing or putting the
Collateral in salable form or selling or disposing of same.

Upon the occurrence and during the continuance of an Event of Default, the Secured Parties
also shall have the right, without notice or demand, either in person, by agent or by a receiver to
be appointed by a court, and without regard to the adequacy of any security for the Secured
Obligations, to take possession of the Collateral or any part thereof and to collect and receive
the rents, issues, profits, income and proceeds thereof. Taking possession of the Collateral shall
not cure or waive any Event of Default or notice thereof or invalidate any act done pursuant to
such notice. The rights, remedies and powers of any receiver appointed by a court shall be as
ordered by said court.

Any public or private sale or other disposition of the Collateral may be held at any office of
the Secured Parties, or at Grantors’ place of business, or at any other place permitted by
applicable law, and without the necessity of the Collateral’s being within the view of prospective
purchasers. The Secured Parties may direct the order and manner of sale of the Collateral, or
portions thereof, as it in its sole and absolute discretion may determine, and Company expressly
waives any right to direct the order and manner of sale of any Collateral. To the extent permitted
by applicable law, the Secured Parties or any Person on the Secured Parties’ behalf may bid and
purchase at any such sale or other disposition. The net cash proceeds resulting from the
collection, liquidation, sale, lease or other disposition of the Collateral shall be applied,
first, to the expenses (including, without limitation, attorneys’ fees and disbursements) of
retaking, holding, storing, processing and preparing for sale or lease, selling, leasing,
collecting, liquidating and the like, and then to the satisfaction of the Secured Obligations in
such order as shall be determined by the Secured Parties in their sole and absolute discretion.
Grantors and any other Person then obligated therefor shall pay to the Secured Parties on demand
any deficiency with regard thereto which may remain after such sale, disposition, collection or
liquidation of the Collateral.

Unless the Collateral is perishable or threatens to decline speedily in value or is of a type
customarily sold on a recognized market, the Secured Parties shall send or otherwise make available
to Grantors notice of the time and place of any public sale thereof or of the time on or after
which any private sale thereof is to be made. The requirement of sending notice conclusively shall
be met if such notice is given in the manner contemplated by the Note Purchase Agreement at least
ten days before the date of the sale. Each Grantor expressly waives any right to receive notice of
any public or private sale of any Collateral or other security for the Secured Obligations except
as expressly provided for in this paragraph.

With respect to any Collateral consisting of securities, partnership or limited liability
company interests, joint venture interests, Investments or the like, and whether or not any of such
Collateral has been effectively registered under the Securities Act of 1933, as amended, or other
applicable laws, the Secured Parties may, in their sole and absolute discretion, sell all or any
part of such Collateral at private sale in such manner and under such circumstances as the Secured
Parties may deem necessary or advisable in order that the sale may be lawfully conducted. Without
limiting the foregoing, the Secured Parties may (i) approach and negotiate with a limited number of
potential purchasers, and (ii) restrict the prospective bidders or purchasers to persons who will
represent and agree that they are purchasing such Collateral for their own account for investment
and not with a view to the distribution or resale thereof. In the event that any such Collateral
is sold at private sale, Grantors agree that if such Collateral is sold for a price which the
Secured Parties in good faith believe to be reasonable under the circumstances then existing, then
(a) the sale shall be deemed to be commercially reasonable in all respects, (b) Grantors shall not
be entitled to a credit against the Secured Obligations in an amount in excess of the purchase
price, and (c) the Secured Parties shall not incur any liability or responsibility to Grantors in
connection therewith, notwithstanding the possibility that a substantially higher price might have
been realized at a public sale. Grantors recognize that a ready market may not exist for such
Collateral if it is not regularly traded on a recognized securities exchange, and that a sale by
the Secured Parties of any such Collateral for an amount substantially less than a pro rata share
of the fair market value of the issuer’s assets minus liabilities may be commercially reasonable in
view of the difficulties that may be encountered in attempting to sell a large amount of such
Collateral or Collateral that is privately traded.

Upon consummation of any sale of Collateral hereunder, the Secured Parties shall have the
right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so
sold. Each such purchaser at any such sale shall hold the Collateral so sold absolutely free from
any claim or right upon the part of Grantors or any other Person, and each Grantor hereby waives
(to the extent permitted by applicable laws) all rights of redemption, stay and appraisal which it
now has or may at any time in the future have under any rule of law or statute now existing or
hereafter enacted. If the sale of all or any part of the Collateral is made on credit or for
future delivery, the Secured Parties shall not be required to apply any portion of the sale price
to the Secured Obligations until such amount actually is received by the Secured Parties, and any
Collateral so sold may be retained by the Secured Parties until the sale price is paid in full by
the purchaser or purchasers thereof. The Secured Parties shall not incur any liability in case any
such purchaser or purchasers shall fail to pay for the Collateral so sold, and, in case of any such
failure, the Collateral may be sold again.

8. Voting Rights; Dividends; etc. With respect to any Collateral consisting of
securities, partnership or limited liability company interests, joint venture interests,
Investments or the like (referred to collectively and individually in this Section 8 and in
Section 9 as the “Investment Collateral”), so long as no Event of Default occurs and remains
continuing:

(a) Voting Rights. Company shall be entitled to exercise any and all voting
and other consensual rights pertaining to the Investment Collateral, or any part thereof,
for any purpose not inconsistent with the terms of this Agreement, the Note Purchase
Agreement; provided, however, that Company shall not exercise, or shall
refrain from exercising, any such right if it would result in an Event of Default.

(b) Dividend and Distribution Rights. Except as otherwise provided in the Note
Purchase Agreement, Grantors shall be entitled to receive and to retain and use any and all
dividends or distributions paid in respect of the Investment Collateral; provided,
however, that any and all such dividends or distributions received in the form of
capital stock, certificated securities, warrants, options or rights to acquire capital stock
or certificated securities forthwith shall be, and the certificates representing such
capital stock or certificated securities, if any, forthwith shall be delivered to the
Secured Parties to hold as pledged Collateral and shall, if received by a Grantor, be
received in trust for the benefit of the Secured Parties, be segregated from the other
property of Grantors, and forthwith be delivered to the Secured Parties as pledged
Collateral in the same form as so received (with any necessary endorsements).

9. Rights During Event of Default. With respect to any Investment Collateral, so long
as an Event of Default has occurred and is continuing:

(a) Voting, Dividend, and Distribution Rights. At the option of the Secured
Parties, all rights of a Grantor to exercise the voting and other consensual rights which it
would otherwise be entitled to exercise pursuant to Section 8(a) above, and to receive the
dividends and distributions which it would otherwise be authorized to receive and retain
pursuant to Section 8(b) above, shall cease, and all such rights thereupon shall become
vested in the Secured Parties which thereupon shall have the sole right to exercise such
voting and other consensual rights and to receive and to hold as pledged Collateral such
dividends and distributions.

(b) Dividends and Distributions Held in Trust. All dividends and other
distributions which are received by a Grantor contrary to the provisions of this Agreement
shall be received in trust for the benefit of the Secured Parties, shall be segregated from
other funds of such Grantor, and forthwith shall be paid over to the Secured Parties as
pledged Collateral in the same form as so received (with any necessary endorsements).

(c) Irrevocable Proxy. Each Grantor does hereby revoke all previous proxies
with regard to the Investment Collateral and appoint the Secured Parties as its proxyholder
to attend and vote at any and all meetings of the shareholders or other equity holders of
the Persons that issued the Investment Collateral and any adjournments thereof, held on or
after the date of the giving of this proxy and prior to the termination of this proxy, and
to execute any and all written consents of shareholders or other equity holders of such
Persons executed on or after the date of the giving of this proxy and prior to the
termination of this proxy, with the same effect as if such Grantor had personally attended
the meetings or had personally voted its shares or other interests or had personally signed
the written consents; provided, however, that the proxyholder shall have
rights hereunder only upon the occurrence and during the continuance of an Event of Default.
Each Grantor hereby authorizes the Secured Parties to substitute another Person as the
proxyholder and, upon the occurrence and during the continuance of any Event of Default,
hereby authorizes the proxyholder to file this proxy and any substitution instrument with
the secretary or other appropriate official of the appropriate Person. This proxy is
coupled with an interest and is irrevocable until such time as all Secured Obligations have
been indefeasibly paid and performed in full.

10. Attorney in Fact. Each Grantor hereby irrevocably nominates and appoints the
Secured Parties as its attorney-in fact for the following purposes: (a) to do all acts and things
which the Secured Parties may deem necessary or advisable to perfect and continue perfected the
security interests created by this Agreement and, upon the occurrence and during the continuance of
an Event of Default, to preserve, process, develop, maintain and protect the Collateral; (b) upon
the occurrence and during the continuance of an Event of Default, to do any and every act which
Company is obligated to do under this Agreement, at the expense of Company and without any
obligation to do so; (c) to prepare, sign, file and/or record, for Company, in the name of Company,
any financing statement, application for registration, or like paper, and to take any other action
deemed by the Secured Parties necessary or desirable in order to perfect or maintain perfected the
security interests granted hereby; and (d) upon the occurrence and during the continuance of an
Event of Default, to execute any and all papers and instruments and do all other things necessary
or desirable to preserve and protect the Collateral and to protect the Secured Parties’ security
interests therein; provided, however, that the Secured Parties shall be under no
obligation whatsoever to take any of the foregoing actions, and, absent gross negligence or actual
malice on the part of the Secured Parties, the Secured Parties shall have no liability or
responsibility for any act taken or omission with respect thereto.

11. Costs and Expenses. Each Grantor agrees to pay to the Secured Parties all costs
and expenses (including, without limitation, attorneys’ fees and disbursements) incurred by the
Secured Parties in the enforcement or attempted enforcement of this Agreement, whether or not an
action is filed in connection therewith, and in connection with any waiver or amendment of any term
or provision hereof. All advances, charges, costs and expenses, including, without
limitation, attorneys’ fees and disbursements, incurred or paid by the Secured Parties in
exercising any right, privilege, power or remedy conferred by this Agreement (including,
without limitation, the right to perform any Secured Obligation of a Grantor under the Note
Purchase Agreement), or in the enforcement or attempted enforcement thereof, shall be secured
hereby and shall become a part of the Secured Obligations and shall be paid to the Secured Parties
by Grantors, immediately upon demand, together with interest thereon at the Default Rate.

12. Statute of Limitations and Other Laws. Until the Secured Obligations shall have
been indefeasibly paid and performed in full, to the extent permitted by applicable law, the power
of sale and all other rights, privileges, powers and remedies granted to the Secured Parties
hereunder shall continue to exist and may be exercised by the Secured Parties at any time and from
time to time irrespective of the fact that any of the Secured Obligations may have become barred by
any statute of limitations. Each Grantor expressly waives the benefit of any and all statutes of
limitation, and any and all laws providing for exemption of property from execution or for
valuation and appraisal upon foreclosure, to the maximum extent permitted by applicable law.

13. Other Agreements. Nothing herein shall in any way modify or limit the effect of
terms or conditions set forth in any other security or other agreement executed by Grantors or in
connection with the Secured Obligations, but each and every term and condition hereof shall be in
addition thereto. All provisions contained in the Note Purchase Agreement are fully applicable to
this Agreement and are incorporated herein by this reference.

14. Understandings With Respect to Waivers and Consents. Each Grantor warrants and
agrees that each of the waivers and consents set forth herein are made after consultation with
legal counsel and with full knowledge of their significance and consequences, with the
understanding that events giving rise to any defense or right waived may diminish, destroy or
otherwise adversely affect rights which Grantors otherwise may have against the Secured Parties or
others, or against Collateral, and that, under the circumstances, the waivers and consents herein
given are reasonable and not contrary to public policy or law. If any of the waivers or consents
herein are determined to be contrary to any applicable law or public policy, such waivers and
consents shall be effective to the maximum extent permitted by law.

15. Release of Grantors. This Agreement shall be released when all Secured
Obligations of Grantors hereunder have been paid in full in cash or otherwise performed in full and
when no portion of the Commitments remains outstanding. Upon such release of Grantors’ Secured
Obligations hereunder, Secured Parties shall return any Collateral to Grantors, or to the Person or
Persons legally entitled thereto, and shall endorse, execute, deliver, record and file all
instruments and documents, and do all other acts and things, reasonably required for the return of
the Collateral to Grantors, or to the Person or Persons legally entitled thereto, and to evidence
or document the release of Secured Parties’ interests arising under this Agreement, all as
reasonably requested by, and at the sole expense of, Grantors.

16. GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF
THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES (OTHER THAN SECTIONS 5-1401 AND
5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW) THEREOF.
