corporation (the "Company"), and each of those persons and entities, severally and not jointly, whose names are set forth on the Schedule of Purchasers
attached hereto as Exhibit A (which persons and entities are hereinafter collectively referred to as
"Purchasers" and each individually as a "Purchaser"). 

Recitals  

        WHEREAS, the Company has authorized the sale and issuance of an aggregate of Eight Million Five Hundred
Forty-Five Thousand Four Hundred Fifty-Five (8,545,455) shares of its Series B Preferred Stock (the "Shares"); 

        WHEREAS, Purchasers desire to purchase the Shares on the terms and conditions set forth herein; and 

        WHEREAS, the Company desires to issue and sell the Shares to Purchasers on the terms and conditions set forth herein; 

        NOW, THEREFORE, in consideration of the foregoing recitals and the mutual promises hereinafter set forth, the parties hereto agree as
follows: 

        1.    AGREEMENT TO SELL AND PURCHASE.    

        1.1    Authorization of Shares.    On or prior to the Closing (as defined in Section 2 below), the Company
shall have authorized (a) the sale and issuance to Purchasers of the Shares and (b) the issuance of such shares of Common Stock to be issued upon conversion of the Shares (the
"Conversion Shares"). The Shares and the Conversion Shares shall have the rights, preferences, privileges and restrictions set forth in the Restated
Certificate of Incorporation of the Company, in the form attached hereto as Exhibit B (the "Restated
Certificate"). 

        1.2    Sale and Purchase.    Subject to the terms and conditions hereof, at the Closing (as hereinafter defined) the
Company hereby agrees to issue and sell to each Purchaser, severally and not jointly, and each Purchaser agrees to purchase from the Company, severally and not jointly, the number of Shares set forth
opposite such Purchaser's name on Exhibit A, at a purchase price of One Dollar and Sixty-Five Cents ($1.65) per share. 

        2.    Closing, Delivery and Payment.    

        2.1    Closing.    The closing of the sale and purchase of the Shares under this Agreement shall take place at
1:00 p.m. on the date hereof, at the offices of Venture Law Group, 2800 Sand Hill Road, Menlo Park, California 94025 or at such other time or place as the Company and Purchasers may mutually
agree (such time and place are designated as the "Initial Closing"). In the event there is more than one closing, the term
"Closing" shall apply to each such closing unless otherwise specified herein. 

        2.2    Delivery.    At each Closing, subject to the terms and conditions hereof, the Company will deliver to each
Purchaser a certificate representing the number of Shares to be purchased at the Closing by such Purchaser, against payment of the purchase price therefor by check, wire transfer made payable to the
order of the Company, cancellation of indebtedness or any combination of the foregoing. 

 

        2.3    Subsequent Closings.    If less than 8,545,455 shares of Series B Preferred Stock are sold at the
Initial Closing, the Company shall have the right, at any time within 180 days of the Initial Closing, to sell such remaining shares of Series B Preferred Stock to one or more additional
purchasers as determined by the Company's Board of Directors, or to any Purchaser hereunder who wishes to acquire additional shares of Series B Preferred Stock at the price and on the terms set
forth herein, provided that any such additional purchaser shall (i) become a party to this Agreement and the Related Agreements (as defined in Section 3.1 below), and (ii) have
the rights and obligations hereunder and thereunder, by executing and delivering to the Company an additional counterpart signature page to each of this Agreement and the Related Agreements. Any
additional purchaser so acquiring shares of Series B Preferred Stock shall be considered a "Purchaser" for purposes of this Agreement, and any
Series B Preferred Stock so acquired by such additional purchaser shall be considered "Shares" for purposes of this Agreement and all other
agreements contemplated hereby. 

        3.    REPRESENTATIONS AND WARRANTIES OF THE COMPANY.    

        Except
as set forth on a Schedule of Exceptions delivered by the Company to the Purchasers at the Closing, the Company hereby represents and warrants to each Purchaser as of the date of
this Agreement as follows: 

        3.1    Organization, Good Standing and Qualification.    The Company is a corporation duly organized, validly existing
and in good standing under the laws of the State of Delaware. The Company has all requisite corporate power and authority to own and operate its properties and assets, to execute and deliver this
Agreement, the Amended and Restated Investor Rights Agreement attached hereto as Exhibit C (the "Investor Rights
Agreement"), the Amended and Restated Voting Agreement attached hereto as Exhibit D (the "Voting
Agreement") and the Amended and Restated Co-Sale Agreement attached hereto as Exhibit E (the
"Co-Sale Agreement") (collectively, the "Related Agreements"), to issue and sell the Shares
and the Conversion Shares, and to carry out the provisions of this Agreement, the Related Agreements and the Restated Certificate and to carry on its business as presently conducted and as presently
proposed to be conducted. The Company is duly qualified and is authorized to do business and is in good standing as a foreign corporation in all jurisdictions in which the nature of its activities and
of its properties (both owned and leased) makes such qualification necessary, except for those jurisdictions in which failure to do so would not have a material adverse effect on the Company or its
business. 

        3.2    Subsidiaries.    The Company does not own or control any equity security or other interest of any other
corporation, limited partnership or other business entity. The Company is not a participant in any joint venture, partnership or similar arrangement. 

        3.3    Capitalization; Voting Rights.    The authorized capital stock of the Company, immediately prior to the Initial
Closing, will consist of: 

        (a)   36,547,850
shares of Common Stock, par value $0.0001 per share, 16,311,129 shares of which are issued and outstanding immediately prior to the Initial Closing. All
issued and outstanding shares of the Company's Common Stock (a) have been duly authorized and validly issued, (b) are fully paid and nonassessable, and (c) were issued in
compliance with all applicable state and federal laws concerning the issuance of securities. The Company has a right of first refusal over transfers of all outstanding shares of Common Stock. 

2

 

        (b)   16,949,500
shares of Preferred Stock, par value $0.0001 per share, 8,404,000 of which are designated Series A Preferred Stock, 6,786,715 of which are issued and
outstanding, and 8,545,500 of which are designated Series B Preferred Stock, none of which are issued or outstanding. All issued and outstanding shares of the Company's Preferred Stock
(a) have been duly authorized and validly issued (b) are fully paid and nonassessable, and (c) were issued in compliance with all applicable state and federal laws concerning the
issuance of securities. The rights, preferences, privileges and restrictions of the Preferred Stock are as stated in the Restated Certificate. Each series of Preferred Stock is convertible into Common
Stock on a one-for-one basis. 

        (c)   The
Company has reserved 9,304,535 shares of Common Stock for issuance to officers, directors, employees and consultants of the Company pursuant to its 2000 Stock Plan
(the "Stock Plan"). Of such reserved shares of Common Stock, 3,823,425 shares have been issued pursuant to restricted stock purchase agreements, options
to purchase 2,137,350 shares have been granted and are currently outstanding or are committed for issuance, and 1,050,000 shares of Common Stock remain available for issuance to officers, directors,
employees and consultants pursuant to the Stock Plan. 

        (d)   Other
than the 9,304,535 shares reserved for issuance under the Company's 2000 Stock Plan and except as may be granted pursuant to the Related Agreements, there are no
outstanding options, warrants, rights (including conversion or preemptive rights and rights of first refusal), proxy or stockholder agreements, or agreements of any kind for the purchase or
acquisition from the Company of any of its securities. 

        3.4    Valid Issuance of Securities.    The Conversion Shares have been duly and validly reserved for issuance. When
issued in compliance with the provisions of this Agreement and the Restated Certificate, the Shares and the Conversion Shares will be validly issued, fully paid and nonassessable, and will be free of
any liens or encumbrances other than liens and encumbrances created by or imposed upon the Purchasers; provided, however, that the Shares and the
Conversion Shares may be subject to restrictions on transfer under state and/or federal securities laws as set forth herein or as otherwise required by such laws at the time a transfer is proposed. 

3

  

        3.5    Authorization; Binding Obligations.    All corporate action on the part of the Company, its officers, directors
and stockholders necessary for the authorization of this Agreement and the Related Agreements, the performance of all obligations of the Company hereunder and thereunder at the Closing and the
authorization, sale, issuance and delivery of the Shares pursuant hereto and the Conversion Shares pursuant to the Restated Certificate has been taken or will be taken prior to the Closing. The
Agreement and the Related Agreements, when executed and delivered, will be valid and binding obligations of the Company enforceable in accordance with their terms, except (a) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other laws of general application affecting enforcement of creditors' rights, (b) general principles of equity that restrict the
availability of equitable remedies, and (c) to the extent that the enforceability of the indemnification provisions in Section 2.9 of the Investor Rights Agreement may be limited by
applicable laws. The sale of the Shares and the subsequent conversion of the Shares into Conversion Shares are not and will not be subject to any preemptive rights or rights of first refusal that have
not been properly waived or complied with. 

        3.6    Financial Statements.    The Company has made available to each Purchaser its financial statements (including
balance sheet, income statement and statement of cash flows) for the fiscal year ended December 31, 2000, for the three-month period ended March 31, 2001 and for the
six-month period ended June 30, 2001 (collectively, the "Financial Statements"). The Financial Statements fairly present the
financial condition and operating results of the Company as of the dates, and for the periods, indicated therein. Except as set forth in the Financial Statements, the Company has no material
liabilities, contingent or otherwise, other than (i) liabilities incurred in the ordinary course of business subsequent to June 30, 2001 and (ii) obligations under contracts and
commitments incurred in the ordinary course of business and not required under generally accepted accounting principles to be reflected in the Financial Statements, which, in both cases, individually
or in the aggregate are not material to the financial condition or operating results of the Company. 

        3.7    Agreements; Action.    

        (a)   Except
for agreements explicitly contemplated hereby and agreements between the Company and its employees with respect to the sale of the Company's Common Stock, there
are no agreements, understandings or proposed transactions between the Company and any of its officers, directors, affiliates or any affiliate thereof. 

        (b)   There
are no agreements, understandings, instruments, contracts, proposed transactions, judgments, orders, writs or decrees to which the Company is a party or to its
knowledge by which it is bound which may involve (i) obligations (contingent or otherwise) of, or payments to, the Company in excess of $25,000, or (ii) the transfer or license of any
patent, copyright, trade secret or other proprietary right to or from the Company (other than licenses arising from the purchase of "off the shelf" or
other standard products), or (iii) indemnification by the Company with respect to infringements of proprietary rights. 

        (c)   The
Company has not (i) declared or paid any dividends, or authorized or made any distribution upon or with respect to any class or series of its capital stock,
(ii) incurred any indebtedness for money borrowed or any other liabilities individually in excess of $25,000 or, in the case of indebtedness and/or liabilities individually less than $25,000,
in excess of $50,000 in the aggregate, (iii) made any loans or advances to any person, other than ordinary advances for travel expenses, or (iv) sold, exchanged or otherwise disposed of
any of its assets or rights, other than the sale of its inventory in the ordinary course of business. 

4

 

        (d)   For
the purposes of subsections (b) and (c) above, all indebtedness, liabilities, agreements, understandings, instruments, contracts and proposed
transactions involving the same person or entity (including persons or entities the Company has reason to believe are affiliated therewith) shall be aggregated for the purpose of meeting the
individual minimum dollar amounts of such subsections. 

        3.8    Obligations to Related Parties.    There are no obligations of the Company to officers, directors, stockholders
or employees of the Company other than (a) for payment of salary for services rendered, (b) reimbursement for reasonable expenses incurred on behalf of the Company and (c) for
other standard employee benefits made generally available to all employees (including stock option agreements outstanding under any stock option plan approved by the Board of Directors of the
Company). None of the officers, directors or stockholders of the Company, or any members of their immediate families, are indebted to the Company. None of the officers or directors of the Company, or
10% stockholders of the Company, or any members of their immediate families, have any direct or indirect ownership interest in any firm or corporation with which the Company is affiliated or with
which the Company has a business relationship, or any firm or corporation which competes with the Company, except that officers, directors and/or stockholders of the Company may own stock in (but not
exceeding two percent (2%) of the outstanding capital stock of) publicly traded companies which may compete with the Company. No officer, director or stockholder, or any member of their immediate
families, is, directly or indirectly, interested in any material contract with the Company (other than such contracts as relate to any such person's ownership of capital stock or other securities of
the Company). The Company is not a guarantor or indemnitor of any indebtedness of any other person, firm or corporation. 

        3.9    Title to Properties and Assets; Liens, Etc.    The Company has good and marketable title to its properties and
assets, and good title to its leasehold estates, in each case subject to no mortgage, pledge, lien, lease, encumbrance or charge, other than (a) those resulting from taxes which have not yet
become delinquent, (b) minor liens and encumbrances which do not materially detract from the value of the property subject thereto or materially impair the operations of the Company, and
(c) those that have otherwise arisen in the ordinary course of business. With respect to the property and assets it leases, the Company and its subsidiaries are in compliance with such leases
and, to the best of the Company's knowledge, hold a valid leasehold interest free of any liens, claims or encumbrances. The Company's and its subsidiaries' property and assets, both owned and leased,
are sufficient to enable it to conduct the Company's and its subsidiaries' business as presently conducted. 

5

 

        3.10    Patents and Trademarks.    The Company owns or possesses sufficient legal rights to all patents, trademarks,
service marks, trade names, copyrights, trade secrets, licenses, information and other proprietary rights and processes necessary for its business as now conducted and as presently proposed to be
conducted, without any known infringement of the rights of others. There are no outstanding options, licenses or agreements of any kind relating to the foregoing, nor is the Company bound by or a
party to any options, licenses or agreements of any kind with respect to the patents, trademarks, service marks, trade names, copyrights, trade secrets, licenses, information and other proprietary
rights and processes of any other person or entity other than such licenses or agreements arising from the purchase of "off the shelf" or standard
products. The Company has not received any communications alleging that the Company has violated any of the patents, trademarks, service marks, trade names, copyrights or trade secrets or other
proprietary rights of any other person or entity. The Company is not aware that any of its employees is obligated under any contract (including licenses, covenants or commitments of any nature) or
other agreement, or subject to any judgment, decree or order of any court or administrative agency, that would interfere with their duties to the Company or that would conflict with the Company's
business as presently conducted. Neither the execution nor delivery of this Agreement or of any Related Agreement, nor the carrying on of the Company's business as presently conducted by the employees
of the Company, will, to the Company's knowledge, conflict with or result in a breach of the terms, conditions or provisions of, or constitute a default under, any contract, covenant or instrument
under which any employee is now obligated. The Company does not believe it is or will be necessary to utilize any inventions, trade secrets or proprietary information of any of its employees made
prior to their employment by the Company, except for inventions, trade secrets or proprietary information that have been assigned to the Company. 

        3.11    Compliance with Other Instruments.    The Company is not in violation or default of any term of its Restated
Certificate or Bylaws, or of any provision of any mortgage, indenture, contract, agreement, instrument or contract to which it is party or by which it is bound or of any judgment, decree, order, writ.
The execution, delivery, and performance of and compliance with this Agreement, and the Related Agreements, and the issuance and sale of the Shares pursuant hereto and of the Conversion Shares
pursuant to the Restated Certificate, will not, with or without the passage of time or giving of notice, result in any such material violation, or be in conflict with or constitute a default under any
such term, or result in the creation of any mortgage, pledge, lien, encumbrance or charge upon any of the properties or assets of the Company or the suspension, revocation, impairment, forfeiture or
nonrenewal of any permit, license, authorization or approval applicable to the Company, its business or operations or any of its assets or properties. 

        3.12    Litigation.    There is no action, suit, proceeding or investigation pending or to the Company's knowledge
currently threatened against the Company that questions the validity of this Agreement, or the Related Agreements or the right of the Company to enter into any of such agreements, or to consummate the
transactions contemplated hereby or thereby, or which might result, either individually or in the aggregate, in any material adverse change in the assets, condition, affairs or prospects of the
Company, financially or otherwise, or any change in the current equity ownership of the Company, nor is the Company aware that there is any basis for any of the foregoing. The foregoing includes,
without limitation, actions pending or threatened (or any basis therefor known to the Company) involving the prior employment of any of the Company's employees, their use in connection with the
Company's business of any information or techniques allegedly proprietary to any of their former employers, or their obligations under any agreements with prior employers. The Company is not a party
or subject to the provisions of any order, writ, injunction, judgment or decree of any court or government agency or instrumentality. There is no action, suit, proceeding or investigation by the
Company currently pending or which the Company intends to initiate. 

6

  

        3.13    Employees.    The Company has no collective bargaining agreements with any of its employees. There is no labor
union organizing activity pending or, to the Company's knowledge, threatened with respect to the Company. The Company is not a party to or bound by any currently effective employment contract,
deferred compensation arrangement, bonus plan, incentive plan, profit sharing plan, retirement agreement or other employee compensation plan or agreement. To the Company's knowledge, no employee of
the Company, nor any consultant with whom the Company has contracted, is in violation of any term of any employment contract, proprietary information agreement or any other agreement relating to the
right of any such individual to be employed by, or to contract with, the Company because of the nature of the business to be conducted by the Company; and to the Company's knowledge the continued
employment by the Company of its present employees, and the performance of the Company's contracts with its independent contractors, will not result in any such violation. The Company has not received
any notice alleging that any such violation has occurred. No employee of the Company has been granted the right to continued employment by the Company or to any material compensation, including,
without limitation, any acceleration of vesting, following termination of employment with the Company, or in connection with a merger, acquisition or sale of all, or substantially all, of the assets
of the Company. The Company is not aware that any officer or key employee, or that any group of key employees, intends to terminate his, her or their employment with the Company, nor does the Company
have a present intention to terminate the employment of any officer, key employee or group of key employees. The Company is not bound by or subject to (and none of its assets or properties is bound by
or subject to) any written or oral, express or implied, contract, commitment or arrangement with any labor union, and no labor union has requested or, to the knowledge of the Company, has sought to
represent any of the employees, representatives or agents of the Company. There is no strike or other labor dispute involving the Company that is pending, or to the knowledge of the Company
threatened, nor is the Company aware of any labor organization activity involving its employees. The employment of each officer and employee of the Company is terminable at the will of the Company.
The Company has complied in all material respects with all applicable state and federal equal employment opportunity laws and with other laws related to employment. 

        3.14    Confidential Information and Invention Assignment Agreements.    Each current employee, officer and consultant
of the Company has executed a Confidential Information and Invention Assignment Agreement in the Company's standard form, a copy of which is attached hereto as Exhibit G. No current employee,
officer or consultant of the Company has excluded works or inventions made prior to his or her employment with or engagement by the Company from his or her assignment of inventions pursuant to such
employee, officer or consultant's Confidential Information and Invention Assignment Agreement. 

        3.15    Registration Rights and Voting Rights.    

        (a)   Except
as required pursuant to the Investor Rights Agreement, the Company is presently not under any obligation, and has not granted any rights, to register (as defined
in Section 1.1 of the Investor Rights Agreement) any of the Company's presently outstanding securities or any of its securities that may hereafter be issued. 

        (b)   To
the Company's knowledge, except as contemplated in the Voting Agreement, no stockholder of the Company has entered into any agreement with respect to the voting of
equity securities of the Company. 

7

 

        3.16    Compliance with Laws; Permits.    The Company is not in violation of any applicable statute, rule, regulation,
order or restriction of any domestic or foreign government or any instrumentality or agency thereof in respect of the conduct of its business or the ownership of its properties which violation would
materially and adversely affect the business, assets, liabilities, financial condition, operations or prospects of the Company. No governmental orders, permissions, consents, approvals or
authorizations are required to be obtained and no registrations or declarations are required to be filed in connection with the execution and delivery of this Agreement and the issuance of the Shares
or the Conversion Shares, except such as has been duly and validly obtained or filed, or with respect to any filings that must be made after the Closing, as will be filed in a timely manner. The
Company has all franchises, permits, licenses and any similar authority necessary for the conduct of its business as now being conducted by it, the lack of which could materially and adversely affect
the business, properties, prospects or financial condition of the Company and believes it can obtain, without undue burden or expense, any similar authority for the conduct of its business as planned
to be conducted. 

        3.17    Offering Valid.    Assuming the accuracy of the representations and warranties of the Purchasers contained in
Section 4.2 hereof, the offer, sale and issuance of the Shares and the Conversion Shares will be exempt from the registration requirements of the Securities Act of 1933, as amended (the
"Securities Act"), and will have been registered or qualified (or are exempt from registration and qualification) under the registration, permit or qualification requirements of all applicable state
securities laws. Neither the Company nor any agent on its behalf has solicited or will solicit any offers to sell or has offered to sell or will offer to sell all or any part of the Shares to any
person or persons so as to bring the sale of such Shares by the Company within the registration provisions of the Securities Act or any state securities laws. 

        3.18    Changes.    Since June 30, 2001, there has not been: 

        (a)   the
acquisition by the Company of any material assets or the incurrence by the Company of any material liabilities; 

        (b)   any
damage, destruction or loss, whether or not covered by insurance, materially and adversely affecting the business, properties, prospects, or financial condition of
the Company; 

        (c)   any
waiver or compromise by the Company or its subsidiaries of a valuable right or of a material debt owed to it; 

        (d)   any
satisfaction or discharge of any lien, claim, or encumbrance or payment of any obligation by the Company or any of its subsidiaries; 

        (e)   any
material change to a material contract or agreement by which the Company or any of its subsidiaries or any of their assets is bound or subject; 

        (f)    any

        4.1    Requisite Power and Authority.    Purchaser has all necessary power and authority under all applicable
provisions of law to execute and deliver this Agreement and the Related Agreements and to carry out their provisions. All action on Purchaser's part required for the lawful execution and delivery of
this Agreement and the Related Agreements have been or will be effectively taken prior to the Closing. Upon their execution and delivery, this Agreement and the Related Agreements will be valid and
binding obligations of Purchaser, enforceable in accordance with their terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or other laws of general

        4.2    Investment Representations.    Purchaser understands that neither the Shares nor the Conversion Shares have
been registered under the Securities Act. Purchaser also understands that the Shares are being offered and sold pursuant to an exemption from registration contained in the Securities Act based in part
upon Purchaser's representations contained in the Agreement. Purchaser hereby represents and warrants as follows: 

         (a)    Purchaser Bears Economic Risk.    Purchaser has substantial experience in evaluating and investing in private
placement transactions of
securities in companies similar to the Company so that it is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its own interests. Purchaser
must bear the economic risk of this investment indefinitely unless the Shares (or the Conversion Shares) are registered pursuant to the Securities Act, or an exemption from registration is available.
Purchaser understands that the Company has no present intention of registering the Shares, the Conversion Shares or any shares of its Common Stock. Purchaser also understands that there is no
assurance that any exemption from registration under the Securities Act will be available and that, even if available, such exemption may not allow Purchaser to transfer all or any portion of the
Shares or the Conversion Shares under the circumstances, in the amounts or at the times Purchaser might propose. 

        (b)    Acquisition for Own Account.    Purchaser is acquiring the Shares and the Conversion Shares for Purchaser's own
account for investment
only, and not with a view towards their distribution. 

         (c)    Purchaser Can Protect Its Interest.    Purchaser represents that by reason of its, or of its management's,
business or financial
experience, Purchaser has the capacity to protect its own interests in connection with the transactions contemplated in this Agreement, and the Related Agreements. Further, Purchaser is aware of no
publication of any advertisement in connection with the transactions contemplated in the Agreement. 

        (d)    Accredited Investor.    Purchaser represents that it is an accredited investor within the meaning of
Regulation D under the
Securities Act. 

         (e)    Company Information.    Purchaser has had an opportunity to discuss the Company's business, management and
financial affairs with
directors, officers and management of the Company and has had the opportunity to review the Company's operations and facilities. Purchaser has also had the opportunity to ask questions of and receive
answers from, the Company and its management regarding the terms and conditions of this investment. 

        (f)    Rule 144.    Purchaser acknowledges and agrees that the Shares, and, if issued, the Conversion Shares must
be held indefinitely
unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Purchaser has been advised or is aware of the provisions of Rule 144
promulgated under the Securities Act as in effect from time to time, which permits limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions,
including, among other things: the availability of certain current public information about the Company, the resale occurring following the required holding period under Rule 144 and the number
of shares being sold during any three-month period not exceeding specified limitations. 

        (g)    Residence.    If the Purchaser is an individual, then the Purchaser resides in the state or province identified
in the address of the
Purchaser set forth on Exhibit A; if the Purchaser is a partnership, corporation, limited liability company or other entity, then the office or
offices of the Purchaser in which its investment decision was made is located at the address or addresses of the Purchaser set forth on  Exhibit A.

Shares are subject to restrictions on transfer as set forth in the Investor Rights Agreement.

applied to agreements between California residents entered into and performed entirely in California, without giving effect to principles of conflicts of law. 

        6.2    Survival. The representations, warranties, covenants and agreements made herein shall survive any investigation made by
any Purchaser and the closing of the transactions contemplated hereby for a period of two (2) years following the Closing. All statements as to factual matters contained in any certificate or
other instrument delivered by or on behalf of the Company pursuant hereto in connection with the transactions contemplated hereby shall be deemed to be representations and warranties by the Company
hereunder solely as of the date of such certificate or instrument. 

        6.3    Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit
of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties hereto and shall inure to the benefit of and be enforceable by each person who shall be a holder of
the Shares from time to time. 

        6.4    Entire Agreement. This Agreement, the Exhibits and Schedules hereto, the Related Agreements and the other documents
delivered pursuant hereto constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof and no party shall be liable or bound to any other in any
manner by any representations, warranties, covenants and agreements except as specifically set forth herein and therein. 

        6.5    Severability. In case any provision of the Agreement shall be invalid, illegal or unenforceable, the validity, legality
and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

        6.6    Amendment and Waiver.    

        (a)   This Agreement may be amended or modified only upon the written consent of the Company and holders of at least a majority
of the Shares (treated as if converted and including any Conversion Shares into which the Shares have been converted that have not been sold to the public). Notwithstanding the foregoing, the parties
hereto agree that the issuance and sale of Shares by the Company to additional Purchasers pursuant to the terms of this Agreement at each Closing will require only the consent of the Company, and will
not be considered an amendment or waiver triggering other required approvals under this Section 6.6. 

14

 

        (b)   The obligations of the Company and the rights of the holders of the Shares and the Conversion Shares under the Agreement
may be waived only with the written consent of the holders of at least a majority of the Shares (treated as if converted and including any Conversion Shares into which the Shares have been converted
that have not been sold to the public). 

        6.7    Delays or Omissions.    It is agreed that no delay or omission to exercise any right, power or remedy accruing
to any party, upon any breach, default or noncompliance by another party under this Agreement, the Related Agreements or the Restated Certificate, shall impair any such right, power or remedy, nor
shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring. It is
further agreed that any waiver, permit, consent or approval of any kind or character on any Purchaser's part of any breach, default or noncompliance under this Agreement, the Related Agreements or
under the Restated Certificate or any waiver on such party's part of any provisions or conditions of the Agreement, the Related Agreements, or the Restated Certificate must be in writing and shall be
effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement, the Related Agreements, the Restated Certificate, by law, or otherwise afforded to any
party, shall be cumulative and not alternative. 

15

  

        6.8    Waiver of Conflicts.    Each party to this Agreement acknowledges that Venture Law Group
("VLG"), outside general counsel to the Company, has in the past performed and is or may now or in the future represent one or more of the Purchasers or
their affiliates in matters unrelated to the transactions contemplated by this Agreement (the "Financing"), including representation of such Purchasers
or their affiliates in matters of a similar nature to the Financing. The applicable rules of professional conduct require that VLG inform the parties hereunder of this representation and obtain their
consent. VLG has served as outside general counsel to the Company and has negotiated the terms of the Financing solely on behalf of the Company. It is the belief of VLG that these terms and conditions
represent an arm's length transaction between the Company and the Purchasers. Purchasers have been represented by independent legal counsel regarding the terms of the Financing. The Company and each
Purchaser hereby (a) acknowledge that they have had an opportunity to ask for and have obtained information relevant to such representation, including disclosure of the reasonably foreseeable
adverse consequences of such representation; (b) acknowledge that with respect to the Financing, VLG has represented solely the Company, and not any Purchaser or any stockholder, director or
employee of the Company or any Purchaser; and (c) gives its informed consent to VLG's representation of the Company in the Financing. 

        6.9    Notices.    All notices required or permitted hereunder shall be in writing and shall be deemed effectively
given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient, if not, then on the
next business day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit
with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent to the Company at the address as set forth on the
signature page hereof and to Purchaser at the address set forth on Exhibit A attached hereto or at such other address as the Company or Purchaser
may designate by ten (10) days advance written notice to the other parties hereto. 

        6.10    Expenses.    Each party shall pay all costs and expenses that it incurs with respect to the negotiation,
execution, delivery and performance of the Agreement except that the Company shall, at the Closing, reimburse the reasonable fees of and expenses of Cooley Godward LLP, special counsel to Spirent, not
to exceed $25,000. 

        6.11    Attorneys' Fees.    In the event that any suit or action is instituted to enforce any provision in this
Agreement, the prevailing party in such dispute shall be entitled to recover from the losing party all fees, costs and expenses of enforcing any right of such prevailing party under or with respect to
this Agreement, including without limitation, such reasonable fees and expenses of attorneys and accountants, which shall include, without limitation, all fees, costs and expenses of appeals. 

        6.12    Titles and Subtitles.    The titles of the sections and subsections of the Agreement are for convenience of
reference only and are not to be considered in construing this Agreement. 

        6.13    Counterparts.    This Agreement may be executed in any number of counterparts, each of which shall be an
original, but all of which together shall constitute one instrument. 

        6.14    Broker's Fees.    Each party hereto represents and warrants that no agent, broker, investment banker, person
or firm acting on behalf of or under the authority of such party hereto is or will be entitled to any broker's or finder's fee or any other commission directly or indirectly in connection with the
transactions contemplated herein. Each party hereto further agrees to indemnify each other party for any claims, losses or expenses incurred by such other party as a result of the representation in
this Section 6.14 being untrue. 

16

 

        6.15    Exculpation Among Purchasers.    Each Purchaser acknowledges that it is not relying upon any person, firm, or
corporation, other than the Company and its officers and directors, in making its investment or decision to invest in the Company. Each Purchaser agrees that no Purchaser nor the respective
controlling persons, officers, directors, partners, agents, or employees of any Purchaser shall be liable to any other Purchaser for any action heretofore or hereafter taken or omitted to be taken by
any of them in connection with the Shares and Conversion Shares. 

        6.16    Confidentiality.    Each party hereto agrees that, except with the prior written consent of the other party,
it shall at all times keep confidential and not divulge, furnish or make accessible to anyone any confidential information, knowledge or data concerning or relating to the business or financial
affairs of the other parties to which such party has been or shall become privy by reason of this Agreement or the Related Agreements, discussions or negotiations relating to this Agreement or the
Related Agreements, the performance of its obligations hereunder or the ownership of the Shares purchased hereunder. The provisions of this Section 6.16 shall be in addition to, and not in
substitution for, the provisions of any separate nondisclosure agreement executed by the parties hereto. 

        6.17    Pronouns.    All pronouns contained herein, and any variations thereof, shall be deemed to refer to the
masculine, feminine or neutral, singular or plural, as to the identity of the parties hereto may require. 

        6.18    California Corporate Securities Law.    THE SALE OF THE SECURITIES WHICH ARE THE SUBJECT OF THIS AGREEMENT HAS
NOT BEEN QUALIFIED WITH THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO
SUCH QUALIFICATION OR IN THE ABSENCE OF AN EXEMPTION FROM SUCH QUALIFICATION IS UNLAWFUL. PRIOR TO ACCEPTANCE OF SUCH CONSIDERATION BY THE COMPANY, THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE
EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED OR AN EXEMPTION FROM SUCH QUALIFICATION BEING AVAILABLE.

        AGREEMENT
AND PLAN OF MERGER, dated as of July 21, 2002, among Spirent plc, a company organized under the laws of England and Wales
("Parent"), Spirent Holdings Corporation, a Delaware corporation ("SHC") and an indirect, wholly-owned
subsidiary of Parent, Cancun Acquisition Corp., a Delaware corporation and a wholly-owned, direct subsidiary of SHC ("Merger Sub") and Caw
Networks, Inc., a Delaware corporation (the "Company"). Capitalized terms used in this Agreement without definition are defined in ARTICLE VIII. 

RECITALS  

        WHEREAS, the respective boards of directors of each of Parent, SHC, Merger Sub and the Company have determined that it is in the best interests of each of their
respective companies and stockholders for Merger Sub to be merged with and into the Company, on the terms and subject to the conditions of this Agreement (the
"Merger"); 

        WHEREAS,
SHC is currently the record holder of 5,515,152 shares of Series B Preferred Stock of the Company (such shares, the "SHC Preferred
Stock"); 

        WHEREAS,
as a result of the Merger, all issued and outstanding shares of, and warrants to purchase, capital stock of the Company (other than the SHC Preferred Stock) shall be converted
into the right to receive the applicable Merger Consideration, and all options to acquire shares of the capital stock of the Company shall be converted into options to purchase shares of the capital
stock of Parent, each on the terms and subject to the conditions set forth herein; and 

        WHEREAS,
Parent's willingness to enter into this Agreement and to consummate the Merger is conditioned upon the execution and delivery of the Pre-Merger Agreement of
Stockholders on the date hereof by Stockholders holding a majority of the issued and outstanding shares of Series A Preferred Stock and Series B Preferred Stock, voting together as a
class, and a majority of the outstanding stock of the Company entitled to vote on the adoption of this Agreement. 

        NOW,
THEREFORE, the Parties agree as follows: 

ARTICLE I 

The Merger

        1.1.    The Merger.    

        (a)    The Merger.    At the Effective Time, Merger Sub shall be merged with and into the Company and the separate
corporate existence of Merger Sub shall cease. The Company will be the surviving corporation in the Merger, and the Company, following the Merger, is sometimes referred to herein as the "Surviving
Corporation". 

        (b)    Effects of the Merger.    The Merger shall, from and after the Effective Time, have all the effects provided
therefor by the DGCL. Without limiting the generality of the foregoing, at the Effective Time all of the property, rights, privileges, powers and franchises of Merger Sub and the Company shall vest in
the Surviving Corporation, and all liabilities and duties of Merger Sub and the Company shall become the liabilities and duties of the Surviving Corporation. If at any time after the Effective Time,
any further action is deemed necessary or desirable to carry out the purposes of this Agreement, the Parties agree that the Surviving Corporation will be authorized to take any and all such action. 

        (c)    Organizational Documents.    The Certificate of Incorporation and Bylaws of the Company shall be amended and
restated as of the Effective Time to read as set forth in Exhibits A and B, respectively, and, as so amended, shall be the Certificate of Incorporation and Bylaws, respectively, of the Surviving
Corporation. 

 

        (d)    Directors and Officers.    As of the Effective Time, the existing directors of the Company shall resign. The
directors of Merger Sub immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation as of the Effective Time, and they shall hold office as set forth in the
Bylaws of the Surviving Corporation. The officers of the Company immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation, and they shall hold office as set
forth in the Bylaws of the Surviving Corporation. 

        1.2.    Conversion of Stock.    At the Effective Time, by virtue of the Merger and without any further action on the
part of the holder of any securities of the Company, Merger Sub, Parent or any other Person: 

        (a)    Conversion of Common Stock.    

          (i)  Each
issued and outstanding share of the common stock of the Company, par value $.0001 per share (the "Common Stock"),
other than shares of Common Stock owned by Dissenting Stockholders and shares of Common Stock held in the Company's treasury, shall be cancelled and extinguished and converted into the right to
receive from SHC, subject to Sections 1.2(a)(i), 1.5 and 1.9, (x) at the Effective Time, cash equal to the Common Stock Closing Amount and
(y) at the Earn-Out Date, the Common Stock Earn-Out Amount, if any. The Common Stock Closing Amount and the Common Stock
Earn-Out Amount, collectively, are herein referred to as the "Common Stock Merger Consideration". All of such outstanding shares of Common
Stock, when so converted, shall cease to have any rights with respect thereto, other than the right to receive the Common Stock Merger Consideration. 

         (ii)  (A)
Conversion of Old Restricted Stock. Each share of Old Restricted Stock that is held as of the Effective Date shall
not be converted as set forth in Section 1.2(a)(i) but instead shall be converted into a right to receive Deferred Consideration pursuant to the following terms: 

	(i)
	At
the request of SHC, Parent shall issue to the trustee of an employee benefit trust (the "Trust") for each such share
of Old Restricted Stock such number of Parent Ordinary Shares equal to (x) the Common Stock Closing Amount, divided by
(y) the Effective Price (converted into U.S. Dollars using the Exchange Rate).

	(ii)
	If,
as of the Effective Time, the Effective Price is greater than the Market Price, SHC shall also pay to the Trust an amount of cash (payable in U.S. dollars, based on
the Exchange Rate) equal to the difference between the Effective Price and such Market Price, multiplied by the number of Parent Ordinary Shares to be issued with respect to such share of Old
Restricted Stock (such cash amount and Parent Ordinary Shares described in Section 1.2(a)(ii)(A)(i) above, collectively, the "Deferred
Consideration").

	(iii)
	If
the Common Stock Earn-Out Amount with respect to any share of Old Restricted Stock is paid to the Trust (in accordance with Section 1.9), then
the Deferred Consideration shall also include the Common Stock Earn-Out Amount payable in respect of such share of Old Restricted Stock pursuant to Section 1.9.

	(iv)
	Subject
to Section 1.2(a)(ii)(C) below, the Deferred Consideration will be held by the Trust for the benefit of the Restricted Stockholder until the date or
dates upon which the Repurchase Rights applicable to the corresponding share of Old Restricted Stock would have otherwise lapsed, in accordance with the terms of such Repurchase Rights and assuming
the Restricted Stockholders continued employment through such dates, regardless of the Restricted Stockholder's continued employment through such dates, and such Deferred Consideration shall be paid
directly to the Restricted Stockholder immediately thereafter. Notwithstanding the foregoing, the Deferred Consideration held by the Trust shall not be subject to any right of repurchase by the Trust
or any other employment-related vesting requirements. 

2

 

        (B)  Conversion of Early Exercise Restricted Stock. Each share of Early Exercise Restricted Stock that is held as of the
Effective Date shall not be converted as set forth in Section 1.2(a)(i) but instead shall be converted into the right to receive Restricted Consideration under the following terms: 

	(i)
	At
the request of SHC, Parent shall issue to the trustee of the Trust for each such share of Early Exercise Restricted Stock such number of Parent Ordinary Shares
("New Restricted Stock") equal to (x) the Common Stock Closing Amount, divided by
(y) the Effective Price (converted into U.S. Dollars using the Exchange Rate). The New Restricted Stock shall be subject to a Repurchase Right
exercisable by the Trust (and the Company hereby assigns such Repurchase Right to the Trust) until such shares of New Restricted Stock vest in accordance with the schedule pursuant to which the
corresponding share of Early Exercise Restricted Stock would have vested.

	(ii)
	The
repurchase price for each share of New Restricted Stock shall equal the product of (x) the repurchase price for the
corresponding share of Early Exercise Restricted Stock as in effect immediately prior to the Effective Time, multiplied by (y) a fraction,
(i) the numerator of which is the Effective Price (converted into U.S. Dollars using the Exchange Rate) and
(ii) the denominator of which is the Common Stock Closing Amount.

	(iii)
	If,
as of the Effective Time, the Effective Price is greater than the Market Price, SHC shall also pay to the Trust an amount of cash (payable in U.S. dollars, based
on the Exchange Rate) equal to the difference between the Effective Price and such Market Price, multiplied by the number of shares of New Restricted Stock to be issued with respect to such share of
Early Exercise Restricted Stock (such cash amount and New Restricted Stock described in Section 1.2(a)(ii)(B)(i) above, collectively, the "Restricted
Consideration"). Such cash amount shall be paid to the Restricted Stockholder if, and only if, and at such time as, such Restricted Stockholder has vested in him or her the
applicable shares of New Restricted Stock pursuant to Section 1.2(a)(ii)(B)(v) below.

	(iv)
	If
the Common Stock Earn-Out Amount with respect to any share of Early Exercise Restricted Stock is paid to the Trust (in accordance with
Section 1.9), then the Restricted Consideration shall also include the Common Stock Earn-Out Amount payable in respect of such share of Early Exercise Restricted Stock pursuant to
Section 1.9.

	(v)
	Notwithstanding
the foregoing, the general provisions governing the vesting of each share of Early Exercise Restricted Stock, as set forth in the stock option agreement
pursuant to which the Early Exercise Restricted Stock was granted, shall continue to apply with respect to the corresponding Restricted Consideration. Subject to Section 1.2(a)(ii)(C) below,
the Restricted Consideration shall be held in escrow by the Trust until the date or dates upon which such Restricted Consideration vests in accordance with this paragraph. 

        (C)  Restricted Stock Assumption Agreements. Each Restricted Stockholder shall execute appropriate agreements, substantially
in the form of Exhibit C hereto, giving effect to this Section 1.2(a)(ii) and acknowledging that the Deferred Consideration or Restricted Consideration, as the case may be, shall
be held as collateral for any note made by such Restricted Stockholder to the Company, if any, in connection with the original issuance of such Restricted Stockholder's shares of Restricted Stock
until the discharge of such note. 

3

 

        (b)    Conversion of Preferred Stock.    

          (i)  Each
issued and outstanding share of Non-SHC Preferred Stock, other than shares of Preferred Stock owned by Dissenting Stockholders and shares of Preferred
Stock held in the Company's treasury, shall be cancelled and extinguished and shall be converted into the right to receive, subject to Section 1.5:
(i) at the Effective Time, cash from SHC equal to (x) the Common Stock Closing Amount, multiplied by
(y) the number of shares of Common Stock into which such share of Non-SHC Preferred Stock is convertible as of the Effective Time (the
"Non-SHC Preferred Stock Closing Amount") and (ii) at the applicable Earn-Out
Date, the Non-SHC Preferred Stock Earn-Out Amount, if any. The Non-SHC Preferred Stock Closing Amount and the Non-SHC Preferred Stock
Earn-Out Amount are collectively herein referred to as the "Non-SHC Preferred Stock Merger Consideration". All of the
outstanding shares of Non-SHC Preferred Stock, at the Effective Time, shall cease to have any rights with respect thereto, other than the right to receive the Non-SHC Preferred
Stock Merger Consideration. 

         (ii)  Each
issued and outstanding share of SHC Preferred Stock shall be converted into the right to receive one ten thousandth (1/10,000) of a share of the common stock of
the Surviving Corporation as of the Effective Time. 

        (c)    Fractional Shares.    No fractional Parent Ordinary Shares shall be issued hereunder. Each Stockholder
otherwise entitled to receive a fraction of a Parent Ordinary Share from Parent pursuant to this Section 1.2 or Section 1.9 shall receive, in lieu thereof, an amount of cash equal to the
Market Price multiplied by the fraction of a Parent Ordinary Share to which such Stockholder would otherwise be entitled at such time. 

        (d)    Cancellation of Treasury Shares.    Each share of the capital stock of the Company held in the Company's
treasury shall be cancelled and no cash, Parent Ordinary Shares or other consideration shall be delivered in exchange therefor. 

        (e)    Capital Stock of Merger Sub.    Each issued and outstanding share of common stock of Merger Sub shall be
converted into one validly issued, fully paid and non-assessable share of common stock of the Surviving Corporation. 

        (f)    Termination of Warrants.    Each warrant to purchase capital stock of the Company that remains unexercised as
of the Effective Time shall be terminated, and no cash, Parent Ordinary Shares or other consideration shall be payable therefor. 

        1.3.    Treatment of Options.    

        (a)   At
the Effective Time, or as soon thereafter as permitted by applicable Law, by virtue of the Merger and without any action taken by any holder of an option (an
"Option") to purchase Common Stock granted to any current employee or director of the Company, each outstanding Option shall be automatically converted
into an option to acquire Parent Ordinary Shares (each, a "New Option") in an amount, at an exercise price and on the terms as provided below: 

          (i)  The
number of Parent Ordinary Shares to be subject to each New Option shall be the number of Parent Ordinary Shares equal to the number of shares of Common Stock
subject to such Option multiplied by a fraction, (x) the denominator of which is the Effective Price (converted into U.S. Dollars using the Exchange
Rate) and (y) the numerator of which is the Common Stock Closing Amount, provided that any fractional
number of Parent Ordinary Shares resulting from such multiplication shall be rounded down to the nearest whole share. 

         (ii)  The
exercise price for each Parent Ordinary Share under each New Option shall be an amount of U.S. Dollars equal to the exercise price per share of Common Stock under
the Option, multiplied by a fraction, (x) the numerator of which is the Effective Price (converted into U.S. Dollars using the Exchange Rate) and
(y) the denominator of which is the Common Stock Closing Amount. 

4

 

        (iii)  In
the event that the Option Earn-Out Amount becomes payable pursuant to Section 1.9, the number of Parent Ordinary Shares subject to each New
Option, and the exercise price with respect to each Parent Ordinary Share subject to such New Option, shall be adjusted to the number of Parent Ordinary Shares and exercise price that would have
resulted pursuant to Section 1.3(a)(i) and 1.3(a)(ii) had the Option Earn-Out Amount for such New Option been taken into account in the determination of such number
and price as of the Effective Time. 

        (iv)  The
terms and conditions (including with respect to the vesting thereof) of the New Options will be substantially the same as the terms and conditions of the cancelled
Options, except as set out in the amended and restated rules of the Plan adopted by Parent and as needed (A) to reflect the change in the security
subject to the New Option, (B) to incorporate the provisions of this Section 1.3, (C) to provide
that such New Options shall be exercisable only by the payment of cash and to the extent permitted by Parent at the date of exercise, by the sale of a number of Parent Ordinary Shares subject to the
Option and (D) to comply with UK securities and company laws and tax and listing requirements. 

        (b)   In
connection with the grant of the New Options, Parent (or its employee benefit trust) shall (i) reserve for issuance or
transfer the number of Parent Ordinary Shares that will become subject to the New Options pursuant to this Section 1.3 and (ii) from and after
the Effective Time, upon exercise of New Options, make available for issuance or transfer all Parent Ordinary Shares covered by such exercised New Options, subject to the terms and conditions
applicable to such New Options. 

        (c)   The
grantee of a New Option shall execute a stock option assumption agreement in the form attached hereto as Exhibit G, which, among other things, shall provide
that such New Option shall be in full and complete satisfaction of any obligation of the Company, the Surviving Corporation or Parent to such holder in respect of the corresponding cancelled Option. 

        (d)   The
assumption and replacement of Options with New Options and the related adjustments provided under this Agreement with respect to any Options that are "incentive
stock options" (as defined in Section 422 of the Code) shall be and are intended to be effected in a manner which is consistent with Section 424(a) of the Code, and the Parties agree to
treat the New Options consistent with such intent. 

        (e)   If
the Effective Price is in excess of the Market Price as of the Closing Date, the holder of each Option will be entitled to receive upon the exercise thereof in
accordance with the terms of the New Option, an amount of cash (payable in U.S. Dollars, based on the Exchange Rate) equal to the difference between such Effective Price and such Market Price, each as
of the Closing Date, multiplied by the number of Parent Ordinary Shares into which such New Option is being exercised. 

        (f)    Each
option to purchase Common Stock held immediately prior to the Effective Time by a Person that is not an employee of the Company shall be cancelled at the Effective
Time, and no consideration shall be payable or issuable therefor, provided that, irrespective of any vesting provisions to the contrary, such Person shall be entitled to exercise his or her option in
full, for cash or in consideration for the conversion of outstanding indebtedness of the Company to such Person, prior to the Effective Time. 

5

 

        1.4.    Closing; Effective Time.    

        (a)    Closing.    The closing of the Merger (the "Closing") shall
take place at the offices of Debevoise & Plimpton, 919 Third Avenue, New York, New York, or such other place and time as may be mutually agreed to by Parent and the Company, as soon as possible
but in no event later than five Business Days after the satisfaction of the conditions set forth in Article VI, except for those conditions that by their terms are satisfied by deliveries at
the Closing, unless the parties otherwise agree in writing. The "Closing Date" shall be the date on which the Closing actually occurs. 

        (b)    Effective Time.    At the Closing, Merger Sub and the Company will cause a Certificate of Merger, substantially
in the form set forth as Exhibit D hereto to be executed and filed with the Secretary of State of the State of Delaware, as required by the DGCL (the "Certificate of
Merger"). When used herein, the term "Effective Time" shall mean the time when the Certificate of Merger has been accepted for
filing and is deemed effective under applicable Law. 

        1.5.    Escrow Arrangements; Repayment of Indebtedness to Company.    

        (a)   At
the Closing, SHC shall deliver the Escrow Amount to the Escrow Agent. The cash that would otherwise be issued to certain Stockholders as of the Effective Time
pursuant to Section 1.2 shall be proportionately reduced (based on the cash that would otherwise be payable pursuant to Section 1.2 to such Stockholders) by an aggregate amount equal to
the Escrow Amount. The Escrow Agent shall hold and release the Escrow Amount in accordance with the terms of the Escrow Agreement. 

        (b)   At
the Closing, SHC shall deliver to the Surviving Corporation the cash that would otherwise be payable pursuant to Section 1.2(a)(i) to a Stockholder who
has outstanding indebtedness to the Company immediately prior to the Effective Time, up to the total amount of such indebtedness, and the amount payable by the Payment Agent to such Stockholder
pursuant to Section 1.6 shall be reduced by such amount. 

        1.6.    Exchange of Certificates.    

        (a)   Prior
to the Effective Time, SHC shall designate The Bank of New York ("BONY") or such other bank or trust company
reasonably satisfactory to Parent and the Company as payment agent for the Merger (the "Payment Agent"). Immediately prior to the Effective Time, SHC
shall deposit or cause to be deposited with the Payment Agent an amount of cash sufficient to enable the Payment Agent to effect, subject to Section 1.5, the cash payments payable as of the
Effective Time pursuant to Sections 1.2(a)(i), 1.2(a)(ii) (if any) and 1.2(b). As soon as practicable after the Effective Time and, in any event, not later than three Business Days after the
Effective Time, SHC and Parent will cause the Payment Agent to deliver by overnight courier to each Stockholder as of the Effective Time a letter of transmittal, which shall be accompanied by a copy
of the Post-Merger Agreement of Stockholders (if such Stockholder was not a party to the Pre-Merger Agreement of Stockholders). The letter of transmittal will include
instructions on how such former Stockholder can surrender its certificates representing, as the case may be, Common Stock or Preferred Stock
("Certificates") in exchange for the applicable Merger Consideration such former Stockholder was entitled to receive as of the Effective Time, and
stating that delivery will be effected, and risk of loss and title to Certificates will pass, only when the former Stockholder delivers those Certificates to the Payment Agent. 

6

 

        (b)   On
surrendering its Certificate to the Payment Agent, and delivering an executed letter of transmittal, a counterpart signature to the Post-Merger Agreement
of Stockholders (if applicable) and an accredited investor questionnaire (if requested), and, in the case of Restricted Stockholders, the agreement referred to in Section 1.2(a)(ii), the holder
of a Certificate will be entitled to receive, and the Payment Agent shall send, within three Business Days after receipt of such materials, properly completed, to all Stockholders other than
Restricted Stockholders, the applicable amount of cash as set forth in Section 1.2(a) or 1.2(b), as applicable (but subject to Section 1.5), paid by check drawn on a U.S. bank, and, to
Restricted Stockholders, an acknowledgement by Parent that the applicable number of Parent Ordinary Shares have been issued to the Trust pursuant to Section 1.2(a)(ii) and an
acknowledgment by the Payment Agent that any cash required to be paid in connection with such issuance of Parent Ordinary Shares pursuant to Section 1.2(a)(ii) has been delivered to the
Trust, and, to the Trust, any such cash. In no event will any holder of a Certificate be entitled to any interest or earnings on the amounts deposited by SHC with the Payment Agent pending
distribution. The Payment Agent shall accept such certificates upon compliance with such reasonable terms and conditions as it may impose to effect orderly payment thereof in accordance with normal
payment practices. If any cash is to be remitted to a name other than that in which the Certificate surrendered for payment is registered, it shall be a condition of such payment that the Certificate
so surrendered shall be properly endorsed, with signature guaranteed, or otherwise in proper form for transfer, and that the Person requesting such payment shall pay to the Surviving Corporation or
the Payment Agent any transfer or other Taxes required by reason of the payment of the applicable Merger Consideration to a Person other than that of the registered holder of the Certificate
surrendered, or establish to the satisfaction of the Surviving Corporation or the Payment Agent that such Tax has been paid or is not applicable. 

        (c)   At
and after the Effective Time, the transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of any of the
Company's securities therein. If, after the Effective Time, Certificates are presented to the Payment Agent for any reason, they shall be cancelled and exchanged as provided for in this
Section 1.6. 

        (d)   All
cash paid, and all Parent Ordinary Shares issued pursuant to this Section 1.6 (along with the cash delivered to the Escrow Agent pursuant to
Section 1.5 and any cash paid with respect to fractional shares pursuant to Section 1.2(c)), will be deemed to have been issued in full satisfaction of all rights relating to the Shares,
other than the right, if any, to receive cash or Parent Ordinary Shares pursuant to Section 1.9. 

        (e)   SHC
may cause the Payment Agent to return any amounts deposited with the Payment Agent remaining unclaimed 365 days after the Effective Time, and thereafter each
remaining holder of a Certificate shall look only to the Surviving Corporation as a general creditor thereof with respect to consideration hereunder to which such holder is entitled upon surrender of
such holder's Certificate. Notwithstanding the foregoing, neither the Payment Agent nor any other Person will be liable to a holder of a Certificate for any amount properly paid and required to be
paid to a public official pursuant to any abandoned property, escheat or similar Laws. 

        (f)    Investment of Payment Fund.    The Payment Agent shall invest any cash included in the Payment Fund as directed
by SHC; provided that such investments shall be in obligations of or guaranteed by the United States of America, in commercial paper obligations rated
A-1 or P-1 or better by Moody's Investors Services, Inc. or Standard & Poor's Corporation, respectively, or in certificates of deposit, bank repurchase agreements
or banker's acceptances of commercial banks with capital exceeding $1 billion. Any net profit resulting from, or interest or income produced by, such investments shall be payable to SHC. 

7

 

        (g)    Lost Certificates.    If any Certificate shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by SHC or Parent, the provision of an indemnity by such Person in form and substance
reasonably acceptable to SHC or Parent against any claim that may be made against it with respect to such Certificate, the Payment Agent shall pay in exchange for such lost, stolen or destroyed
Certificate the applicable Merger Consideration therefor pursuant to this Agreement. 

        (h)    Withholding Right.    Parent, SHC or the Payment Agent shall be entitled to deduct and withhold from the
consideration otherwise payable pursuant to this Agreement to any holder of a Certificate or an Option such amounts as Parent, SHC or the Payment Agent is required to deduct and withhold with respect
to the making of such payment under the Code or any provisions of state, local or foreign tax law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by
Parent, SHC or the Payment Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the certificate in respect of which such deduction and
withholding was made by Parent, SHC or the Payment Agent. 

        1.7.    Legends; Restrictions.    

        (a)    General Legend.    The certificates for the Parent Ordinary Shares issued in connection with the Merger
(including upon exercise of any New Options) will bear the following legends (or substantially similar legends): 

        THESE
SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR QUALIFIED UNDER ANY STATE SECURITIES LAWS (THE "SECURITIES ACTS"). THE SECURITIES MAY NOT BE
OFFERED, SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT (i) UPON SUCH REGISTRATION, (ii) ON THE

8

 

        1.8.    Shares of Dissenting Stockholders.    

        (a)   Notwithstanding
anything in this Agreement to the contrary, any issued and outstanding Shares held by a Person who (i)
has neither voted in favor of the Merger nor consented in writing to it and who otherwise complies with the provisions of the DGCL concerning the right of holders of Shares to dissent from the Merger
and require appraisal of their Shares, or (ii) has not voted in favor of the Merger and who otherwise complies with the provisions of the California
General Corporation Law (the "California Statute") concerning the right of holders of Shares to dissent from the Merger and require the purchase of
their Shares for cash (in each case, each such Person, a "Dissenting Stockholder", and such shares, the "Dissenting
Shares") will not be converted as described in Section 1.2, but will become the right to receive the consideration determined to be due to that Dissenting Stockholder
under the DGCL and the California Statute. 

        (b)   If,
after the Effective Time, any Dissenting Stockholder withdraws, fails to perfect or otherwise loses his, her or its demand for appraisal or purchase for cash under
the DGCL or the California Statute, as applicable, each of such Dissenting Stockholder's Shares will be deemed to be converted as of the Effective Time into the right to receive the Common Stock
Merger Consideration or the Non-SHC Preferred Stock Merger Consideration, as the case may be, in the manner contemplated by Section 1.2. 

        (c)   The
Company or, after the Effective Time, the Surviving Corporation, will give Parent: 

          (i)  prompt
notice of any demands for appraisal or purchase of Shares it receives; and 

         (ii)  the
opportunity to participate in and direct all negotiations and proceedings with respect to those demands. 

The
Company or, after the Effective Time, the Surviving Corporation, will not, without the Parent's prior written consent, make any payment with respect to, or settle, offer to settle or otherwise
negotiate, any such demands. 

        1.9.    Earn-Out.    

        (a)   Following
the Effective Time, SHC will be obligated to pay additional cash in connection with the Merger if and to the extent required by this Section 1.9,
provided that SHC shall have the option of requiring Parent to issue Parent Ordinary Shares in lieu of such cash. 

        (b)   The
amount of cash payable by SHC or the number of Parent Ordinary Shares to be issued by Parent, as the case may be, if any, will be determined as follows, subject to
Section 1.9(b)(vi): 

          (i)  If
(x) the Integrated Revenues during the period commencing January 1, 2003 and ending December 31, 2003 (the
"Earn-Out Period") are equal to or less than $25 million, and (y) the requirements specified in
Section 1.9(b)(vii) are not met, then SHC shall not be obligated to pay any amount. 

         (ii)  [reserved]

        (iii)  If
the Integrated Revenues during the Earn-Out Period are greater than $25 million and less than or equal to $28 million and SHC elects to
pay in cash, then SHC shall pay for each $100,000.00 of such Integrated Revenues greater than $25 million, the sum of $666,666.67 plus the Equity-Based Adjustment. If the Integrated Revenues
during the Earn-Out Period are greater than $25 million and less than or equal to $28 million and SHC elects to require Parent to issue Parent Ordinary Shares, then Parent
shall issue Parent Ordinary Shares having an Earn-Out Value of $666,666.67 for each $100,000.00 of such Integrated Revenues greater than $25 million. 

9

 

        (iv)  If
the Integrated Revenues during the Earn-Out Period are greater than $28 million and less than or equal to $33 million and SHC elects to pay
in cash, then SHC shall pay (x) the sum of $20 million and the Equity-Based Adjustment plus (y) for each $100,000.00 of such Integrated Revenues greater than $28 million,
$400,000.00 plus the Equity-Based Adjustment. If the Integrated Revenues during the Earn-Out Period are greater than $28 million and less than or equal to $33 million and SHC
elects to require Parent to issue Parent Ordinary Shares, then Parent shall issue Parent Ordinary Shares having an Earn-Out Value of (x) $20 million plus (y) for each
$100,000.00 of such Integrated Revenues greater than $28 million, $400,000.00. 

         (v)  If
the Integrated Revenues during the Earn-Out Period are greater than $33 million and SHC elects to pay in cash, then SHC shall pay the lesser of
(A) the sum of $50 million and the Equity-Based Adjustment and (B) (x) the sum of $40 million and the Equity-Based Adjustment, plus (y) for each $100,000.00 of such
Integrated Revenues greater than $33 million, the sum of $142,857.15 and the Equity-Based Adjustment. If the Integrated Revenues during the Earn-Out Period are greater than
$33 million and SHC elects to require Parent to issue Parent Ordinary Shares, then Parent shall issue Parent Ordinary Shares having an Earn-Out Value of the lesser of
(A) $50 million and (B) (x) $40 million plus (y) for each $100,000.00 of such Integrated Revenues greater than $33 million, $142,857.15. 

        (vi)  Notwithstanding
anything to the contrary contained herein, if SHC chooses to require Parent to issue additional Parent Ordinary Shares pursuant to this
Section 1.9(b), and the Market Price exceeds £2.40, the number of Parent Ordinary Shares to be issued pursuant to this Section 1.9 shall be reduced to such number of Parent
Ordinary Shares having an Aggregate Market Value equal to (x) the number of Parent Ordinary Shares that would, but for this Section 1.9(b)(vi), have been issued, multiplied by
(y) £2.40. 

       (vii)  An
amount of $10 million will be earned and paid in accordance with the provisions of this Section 1.9(b) if
(A) Integrated Revenues during the Earn-out Period are greater than $22 million, and
(B) prior to June 1, 2003, the following requirements have been met in respect of the software that forms part of Parent's Spirent Communications
Teracaw product: 

	(x)
	implementation,
demonstration and documentation of the architecture and design of a split of the product load generator application (the "application") from the protocol stack (the
"stack") such that each of the application and the stack are capable or running on separate central processing units; and

	(y)
	implementation,
demonstration and documentation of the architecture and design that both the application and the stack once split in accordance with paragraph (x) above are
multi-threaded. 

The
requirements set forth in the foregoing clause (B) may be amended by mutual agreement in writing from time to time between Parent's Spirent Communications VP Engineering PAB Calabasas and
the Company's VP Engineering. 

If
a payment is required to be made under this Section 1.9(b)(vii) and SHC elects to pay cash, SHC shall pay $10 million plus the Equity-Based Adjustment. If SHC elects to require
Parent to issue Parent Ordinary Shares then Parent shall issue Parent Ordinary Shares having an Earn-Out Value of $10 million. 

        (c)   Integrated
Revenues will be determined in the following manner: 

          (i)  On
the earlier of the date that is seven days following Parent's public announcement of its audited results for the period ending December 31, 2003 and
February 28, 2004, Parent will provide the Stockholders' Agents with a written notice (the "Earn-Out Statement") certifying the
amount of Integrated Revenues for the Earn-Out Period (the "Integrated Revenues Calculation"). 

10

 

         (ii)  The
Earn-Out Statement will be accompanied by evidence, in a form reasonably satisfactory to the Stockholders' Agents, supporting such calculations
contained therein. The Surviving Corporation and Parent will timely give, and will cause its advisors, counsel and accountants to timely give, the Stockholders' Agents reasonable access to the
Surviving Corporation's and Parent's books, records and personnel reasonably needed for the Stockholders' Agents to verify the Integrated Revenues Calculation stated in the Earn-Out
Statement. 

        (iii)  The
Earn-Out Statement will become final on the 30th day after its delivery unless the Stockholders' Agents provide the Parent with a written
notice on or before this date specifying in reasonable detail the amount by which and the reasons they think that the Integrated Revenues Calculation either contains mathematical errors or was not
determined in accordance with this Section 1.9 (a "Dispute Notice"). 

        (iv)  If
the Stockholders' Agents deliver a Dispute Notice under Section 1.9(c)(iii), then Parent and the Stockholders' Agents will seek to resolve their disagreement
on the Integrated Revenues Calculation by good faith negotiation for 30 days and, if this fails, the Parties will refer the dispute to the Los Angeles office of Deloitte & Touche, LLP
(the "Accountants") to resolve such dispute. Parent, on the one hand, and the Stockholders, on the other hand, shall share equally the costs of the
Accountants' determination of Integrated Revenues. The determination by the Accountants of the Integrated Revenues for the applicable period shall be final, binding and conclusive on the parties. 

         (v)  SHC
will pay the Earn-Out Amounts in accordance with Section 1.9(d) on March 31, 2004, unless the Integrated Revenues Calculation remains in
dispute as of March 17, 2004, in which case SHC will pay the Earn-Out Amounts on the date that is 10 Business Days after the earlier of: 

	(A)
	Parent
and the Stockholders' Agents reaching agreement under Section 1.9(c)(iv); or

	(B)
	the
Accountants rendering their decision under Section 1.9(c)(iv). 

11

  

The
date that the Earn-Out Amounts are required to be paid hereunder is referred to as the "Earn-Out Date". 

        (d)   The
cash payable or Parent Ordinary Shares issuable pursuant to this Section 1.9 shall be allocated to all Stockholders and all holders of Options as of the
Effective Time, on a Pro Rata Basis. 

        (e)   The
cash or Parent Ordinary Shares, if any, allocated with respect to one share of Non-SHC Preferred Stock outstanding as of the Effective Time under this
Section 1.9 are herein referred to as the "Non-SHC Preferred Stock Earn-Out Amount." The cash or Parent Ordinary Shares,
if any, allocated with respect to one share of Common Stock as of the Effective Time under this Section 1.9 are herein referred to as the "Common Stock
Earn-Out Amount." The additional cash or Parent Ordinary Shares, if any, allocated to a New Option in accordance with Section 1.3(a)(iii) pursuant to
this Section 1.9 are herein referred to as the "Option Earn-Out Amount". The Non-SHC Preferred Stock Earn-Out
Amount, the Common Stock Earn-Out Amount and the Option Earn-Out Amount, collectively, are herein referred to as the "Earn-Out
Amounts". If all of the Parent Ordinary Shares issuable as of the Effective Date with respect to a share of Restricted Stock have been released by the Trust to the applicable
Restricted Stockholder as of the Earn-Out Date, the Common Stock Earn-Out Amount, if any, will be paid directly to the applicable Restricted Stockholder. If all of the Parent
Ordinary Shares issuable as of the Effective Date with respect to a share of Restricted Stock remain held by the Trust as of the Earn-Out Date, the Common Stock Earn-Out
Amount, if any, will be paid to the Trust for the benefit of the applicable Restricted Stockholder and shall be held in the same manner as the cash or Parent Ordinary Shares issued to the Trust with
respect to such Restricted Stockholder as of the Effective Time are held. If a portion, but not all, of the Parent Ordinary Shares issuable as of the Effective Date with respect to a share of
Restricted Stock remains held by the Trust as of the Earn-Out Date, the Common Stock Earn-Out Amount, if any, will be paid to the applicable Restricted Stockholder and the
Trust proportionately. 

        (f)    Cash
or Parent Ordinary Shares, if any, allocated to any Dissenting Stockholder (other than Dissenting Stockholders referred to in Section 1.8(b)) or a holder of
Options or a holder of Restricted Stock as of the Effective Time who forfeited its, his or her New Options or from whom New Restricted Stock has been repurchased by the Trust prior to the applicable
Earn-Out Date, shall not be paid or issued, as the case may be. 

        1.10.    Actions With Respect to Non-Accredited Investors.    If Parent, SHC and Merger Sub shall have not
received questionnaires (or other evidence satisfactory to Parent) sufficient to satisfy the condition set forth in Section 6.2.12 within ten days following the date of this Agreement (and in
any event prior to the mailing to Stockholders of any of the Notice to Stockholders, the Information Statement or the letter of transmittal referred to in Section 1.6), either
(a) the Company shall cause such condition to be met by procuring the purchase of shares of capital stock of the Company held by certain Stockholders
who are not accredited investors, or (b) Parent shall be entitled to designate certain Stockholders who are not accredited investors (as Parent may
determine in consultation with the Company) as not eligible to receive Parent Ordinary Shares. Any Stockholder so designated will receive, in lieu of Parent Ordinary Shares, cash of equivalent value
determined in accordance with the principles set forth in Sections 1.2(a)(ii) or 1.9, as applicable.

        9.7.    No Third Party Beneficiaries.    Except for the right of the Stockholders to receive the Merger Consideration
at or after the Effective Time, nothing in this Agreement confers any rights on any Person other than the Parties and their respective heirs, successors and permitted assigns. 

        9.8.    Amendment; Waivers, etc.    

        (a)    Writing Requirement.    No amendment, modification or discharge of this Agreement, and no waiver under it, will
be valid or binding unless in writing and duly executed by the party against whom enforcement of the amendment, modification, discharge or waiver is sought. 

        (b)    Extent of Waiver.    Any such waiver under this Agreement will constitute a waiver only with respect to the
specific matter described in the writing and will not impair the rights of the party granting the waiver in any other respect or at any other time. Neither the waiver by any of the Parties of a breach
of or a default under any of the provisions of this Agreement, nor the failure by any of the Parties, on one or more occasions, to enforce any of the provisions of this Agreement or to exercise any
right or privilege under it, will constitute a waiver of any other breach or default of a similar nature, or a waiver of any of such provisions, rights or privileges. 

        9.9.    Survival; Remedies.    

        (a)   The
representations and warranties in this Agreement will survive the execution and delivery of this Agreement, any examination by or on behalf of the Parties and the
completion of the transactions contemplated by this Agreement as set forth in the Agreement of Stockholders. 

57

 

        (b)   Prior
to the Effective Time, the Company shall indemnify the Buyer Indemnitees (as such term is defined in the Agreement of Stockholders) for any Losses (as such term is
defined in the Agreement of Stockholders) incurred by the Buyer Indemnitees arising out of a breach by the Company of this Agreement, and Parent, SHC and Merger Sub shall indemnify the Seller
Indemnitees (as such term is defined in the Agreement of Stockholders) for any Losses (as such term is defined in the Agreement of Stockholders) incurred by the Seller Indemnitees arising out of a
breach by Parent, SHC or Merger Sub of this Agreement. 

        (c)   The
Company acknowledges and agrees that Parent would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their
specific terms and that any breach of this Agreement by the Company could not be adequately compensated in all cases by monetary damages alone. Parent, SHC and Merger Sub acknowledge and agree that
the Company would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms and that any breach of this Agreement by Parent, SHC or
Merger Sub could not be adequately compensated in all cases by monetary damages alone. Accordingly, in addition to any other right or remedy to which Parent or the Company may be entitled at law or in
equity, each of Parent and the Company shall be entitled to enforce any provision of this Agreement by a decree of specific performance and to temporary, preliminary and permanent injunctive relief to
prevent breaches or threatened breaches of any of the provisions of this Agreement, without posting any bond or undertaking. 

        (d)   The
rights and remedies in this Agreement are cumulative and none excludes any other, or any rights or remedies that a party hereto may otherwise have at law or in
equity, subject, however, to the limitations on rights and remedies set forth in Section 4(g) of the Agreement of Stockholders. 

        (e)   The
rights and remedies of any party based on, arising out of or otherwise in respect of any inaccuracy or breach of any representation, warranty, covenant or agreement
or failure to fulfill any condition are not limited by the fact that the act, omission, occurrence or other state of facts on which any claim of such an inaccuracy or breach is based may also be the
subject matter of another representation, warranty, covenant or agreement as to which there is no inaccuracy or breach. The representations and warranties of the Company and of Parent, SHC and Merger
Sub will not be affected or waived because of any investigation made by or on behalf of Parent, SHC or Merger Sub (including by any of their advisors, consultants or Representatives), in the case of
the representations and warranties of the Company, or by or on behalf of the Company (including but not limited to by way of its advisors, consultants or Representatives), in the case of the
representations and warranties of Parent, SHC and Merger Sub or because Parent, SHC or Merger Sub, on the one hand, or the Company, on the other hand, or any of those advisors, consultants or
Representatives knew or should have known that the representation or warranty is or might be inaccurate. 

        9.10.    Entire Agreement.    This Agreement, including the Company Disclosure Schedules and other Schedules and
Exhibits, the other Transaction Agreements and the Confidentiality Agreement constitute the entire agreement of, and supersede all prior agreements and understandings (both written and oral) between,
the Parties with respect to its subject matter. 

        9.11.    Severability.    If any provision (including any phrase, sentence, clause, section or subsection) of this
Agreement is invalid, inoperative or unenforceable for any reason, this will not make that provision invalid, inoperative or unenforceable in any other case or circumstance, or make any other
provision invalid, inoperative, or unenforceable. 

        9.12.    Headings.    The headings in this Agreement are for convenience only and do not affect its interpretation. 

58

 

        9.13.    Counterparts.    This Agreement may be executed in several counterparts, each of which will be deemed an
original and all of which will together constitute one and the same instrument. 

        9.14.    U.S. Securities Laws.    This Agreement, the negotiations relating to it and the transactions contemplated by
it do not constitute an offer of Parent Ordinary Shares to any Person that is not an "accredited investor", as defined in Rule 501 under the Securities Act. 

        9.15.    Guarantee of Performance.    Parent will cause SHC and Merger Sub to perform their respective obligations
under this Agreement, subject to its terms and conditions, and shall guarantee their performance to the extent not so performed by SHC or Merger Sub. 

59

   
        The Parties have duly executed this Agreement as of the date first written above.

properties of the Company and its Subsidiaries, taken as a whole, except
changes that individually or in the aggregate could not reasonably be expected
to have a Material Adverse Effect. 
There is no fact known to the Company that could reasonably be expected
to have a Material Adverse Effect that has not been set forth herein or in the
Information Pack or in the other documents, certificates and other writings
delivered to the Noteholders by or on behalf of the Company specifically for
use in connection with the transactions contemplated hereby.

 

(b) Projections.          All information provided by the Company to each
Noteholder that constitutes forecasts or projections relating to the Company
and its Subsidiaries (including without limitation, the forecasts and
projections contained in the Information Pack), were arrived at after careful
consideration and, in view of the circumstances existing at the time such
forecasts and projections were made, is based on information that the Company
believed to be complete and accurate at the time of the preparation thereof and
at the time that such forecasts and projections were supplied and, to the
knowledge of the Company, does not contain any untrue statement of a material
fact or omit to state any fact necessary to make such forecasts and projections
not materially misleading in light of the circumstances under which such
forecasts and projections were prepared (although no representation or warranty
is hereby made that such condition or performance will actually be
achieved).  All material assumptions and
estimates upon which any such forecasts or projections have been based are
reasonable in view of the circumstances existing at the

 

31

 

time such assumptions and estimates were
made, and since such time, to the knowledge of the Company, there has been no
change in such circumstances, or change in such assumptions and estimates upon
which such forecasts and projections were based, which would materially adversely
affect such forecasts or projections.

 

5.4.                            Organization and Ownership of Shares of
Subsidiaries; Affiliates.

 

(a) Schedule 5.4 contains (except as noted
therein) a group structure chart complete and correct in all material respects
and as previously provided to PricewaterhouseCoopers together with complete and
correct lists of:

 

(i)                                  each
of the Subsidiaries of the Company that, as at December 31, 2002,
principally affects the financial statements of the Group (as set forth in the
financial statements of the Group dated such date) showing, as to each such
Subsidiary, the correct name thereof, the jurisdiction of its organization, and
the percentage of each class of its common equity securities (and securities
convertible into or exchangeable for such common equity securities) owned by
the Company directly or indirectly;

 

(ii)                              the
Material Subsidiaries of the Company, (A) showing, as to each such Material
Subsidiary, the correct name thereof, the jurisdiction of its organization, and
the percentage of each class of its common equity securities (and securities
convertible into or exchangeable for such common equity securities) owned by
the Company and each Subsidiary, (B) listing such Material Subsidiaries in
descending order of their contribution to Consolidated EBIT (and, where the
Consolidated EBIT for two or more Material Subsidiaries is the same, in
descending order of their contribution to Consolidated Total Assets) for the
Accounting Period ending on December 31, 2002, (C) stating that, as of the end
of the

 

32

 

Accounting Period ending on December 31,
2002, the aggregate of the EBIT and Total Assets of all such Material
Subsidiaries plus the EBIT and Total Assets of the Company accounts for at
least 80% of Consolidated EBIT and 80% of Consolidated Total Assets for, and as
at the end of, such Accounting Period, respectively, and (D) setting out the
proportion which the aggregate EBIT and Total Assets of the Company and all
such Material Subsidiaries bears to the Consolidated EBIT and Consolidated
Total Assets as at the end of the Accounting Period ending on December 31,
2002;

 

(iii)                          the
Affiliates (other than Subsidiaries) of the Company; and

 

(iv)                            the
directors of the Company.

 

(b) All of the outstanding share capital and
shares of other common equity securities (and securities convertible into or
exchangeable for such common equity securities) of each Material Subsidiary
shown in Schedule 5.4 as being owned by the Company or a Subsidiary have been
validly issued, and, in the case of Subsidiaries organized under the laws of
the United States or any state thereof, are fully paid and nonassessable and
are owned by the Company or a Subsidiary free and clear of any Lien (except as
otherwise disclosed in Schedule 5.13).

 

(c) Each Material Subsidiary identified in
Schedule 5.4 is a corporation or other legal entity duly organized, validly
existing and (to the extent such concept is recognized in such jurisdiction) in
good standing under the laws of its jurisdiction of organization, and is duly
qualified as a foreign corporation or other legal entity and (to the extent
such concept is recognized in such jurisdictions) is in good standing in each
jurisdiction in which such qualification is required by law, other than those
jurisdictions as to which the failure to be so qualified or in good standing
could not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect.  Each such
Material Subsidiary has the corporate or other power and authority to own or
hold under lease the properties it purports to

 

33

 

own or hold under lease and to transact the
business it transacts and proposes to transact as described in the Information
Pack.

 

(d) No Subsidiary is a party to, or otherwise
subject to, any legal restriction or any agreement (other than this Agreement,
the agreements listed on Schedule 5.4 and customary limitations imposed by
corporate law statutes) restricting the ability of such Subsidiary to pay
dividends out of profits or make any other similar distributions of profits to
the Company or any Subsidiary that owns outstanding share capital or shares of
other common equity interests of such Subsidiary (except, in the case of any
Subsidiary that is not a Material Subsidiary, where such restriction or
agreement could not reasonably be expected to have a Material Adverse Effect).

 

5.5.                            Financial Statements.

 

The Company has
delivered to each Noteholder copies of the consolidated financial statements of
the Group listed on Schedule 5.5.  The
financial statements dated as of December 31, 2001 (including in each case the
related schedules and notes) have been prepared in accordance with UK GAAP as
at December 31, 2001 consistently applied throughout the periods involved,
except as set forth in the notes thereto, and present a true and fair view of
the consolidated financial position and results of operations and cash flows of
the Company and its Subsidiaries as of the respective dates and for the respective
periods specified in such Schedule 5.5. 
The other financial statements listed in Schedule 5.5 have been prepared
in accordance with UK GAAP consistently applied throughout the periods involved
and using accounting policies consistent with those used by the Company and the
Subsidiaries in their most recent audited accounts, except where any changes,
and the reasons therefor, have been disclosed in such financial
statements.  In the case of each
Guarantor which produces audited accounts, its audited accounts dated as of
December 31, 2001 (including in each case the related schedules and notes) have
been prepared in accordance with UK GAAP as at December 31, 2001 consistently
applied throughout the periods involved, except

 

34

 

as set forth in the notes thereto, and
present a true and fair view of the financial position and results of
operations and cash flows of such Guarantor as of the date to which they were
drawn up.  In the case of a Guarantor
which does not produce audited accounts, the accounts of such Guarantor dated
as of December 31, 2001 (including in each case the related schedules and
notes) have been prepared in accordance with accounting principles required in
order to consolidate the accounts of that Guarantor into the consolidated
accounts of the Company.  As at the
Effective Date, there has been no material adverse change in the consolidated
financial condition of the Company and its Subsidiaries taken as a whole since
December 31, 2001.

 

5.6.                            Compliance with Laws, Other Instruments, etc.

 

The execution,
delivery and performance by the Company of the Financing Documents to which it
is a party will not:

 

 

(a) contravene,
result in any breach of, or constitute a default under, or result in the
creation of any Lien in respect of any property of the Company or any
Subsidiary under, any indenture, mortgage, deed of trust, loan, purchase or
credit agreement, lease,
memorandum or articles of association, corporate charter or by-laws, or any
other agreement or instrument to which the Company or any Subsidiary is bound
or by which the Company or any Subsidiary or any of their respective properties
may be bound or affected;

 

(b) conflict with or result in a breach of any of the terms, conditions
or provisions of any order, judgment, decree, or ruling of any court,
arbitrator or Governmental Authority applicable to the Company or any
Subsidiary; or

 

(c) violate any provision of any statute or other rule or regulation of
any Governmental Authority applicable to the Company or any Subsidiary.

 

35

 

5.7.                            Governmental Authorizations, etc.

 

No consent, approval or authorization of, or
registration, filing or declaration with, any Governmental Authority is
required in connection with the Restructuring Transaction or in connection with
the execution, delivery, or performance by the Company or any Guarantor, or the
enforceability against the Company or any such Guarantor, of the Financing
Documents to which the Company or such Guarantor is a party, or in connection
with the validity of such Financing Documents.

 

5.8.                            Litigation; Observance of Agreements, Statutes and Orders.

 

(a) Except as disclosed on Schedule 5.8,
there are no actions, suits or proceedings pending or, to the knowledge of the
Company, threatened against or affecting the Company or any Subsidiary or any
property of the Company or any Subsidiary in any court or before any arbitrator
of any kind or before or by any Governmental Authority that, individually or in
the aggregate, could reasonably be expected to have a Material Adverse Effect.

 

(b) Neither the
Company nor any Subsidiary is in default under any term of any agreement or
instrument to which it is a party or by which it is bound, or any order, judgment,
decree or ruling of any court, arbitrator or Governmental Authority or is in
violation of any applicable law, ordinance, rule or regulation (including,
without limitation, Environmental Laws) of any Governmental Authority, which
default or violation, individually or in the aggregate, could reasonably be
expected to have a Material Adverse Effect.

 

5.9.                            Taxes.

 

The Company and the Subsidiaries have filed
all income and other Material tax returns that are required to have been filed
by such companies in any

 

36

 

jurisdiction, and have paid all taxes shown
to be due and payable on such returns and all other taxes and assessments
levied upon them or their properties, assets, income or franchises, to the extent
such taxes and assessments have become due and payable and before they have
become delinquent, except for any taxes and assessments (a) the amount of which
is not individually or in the aggregate Material, or (b) the amount,
applicability or validity of which is currently being contested in good faith
by appropriate proceedings and with respect to which the Company or such
Subsidiary, as the case may be, has established adequate reserves or provisions
in accordance with, and to the extent required by, Applicable GAAP. The Company
knows of no basis for any other tax or assessment that could reasonably be
expected to have a Material Adverse Effect. 
The charges, accruals and reserves on the books of the Company and its
Subsidiaries as at the date hereof in respect of taxes for all completed
financial periods are adequate under UK GAAP. 
The United Kingdom income tax liabilities of the Company and its
Subsidiaries have been finally determined by the United Kingdom Inland Revenue
and paid for all tax years up to and including the tax year ending December 31,
1998.

 

5.10.                     Title to Property; Leases.

 

Each of the Company and its Subsidiaries has
good and sufficient title to their respective properties that, individually or
in the aggregate, are Material including all such properties reflected in the
most recent audited balance sheet referred to in Section 5.5 or purported to
have been acquired by the Company or any Subsidiary after said date (except as
sold or otherwise disposed of in the ordinary course of business), in each case
free and clear of Liens prohibited by this Agreement.  All leases that, individually or in the aggregate, are Material
are valid and subsisting and are in full force and effect in all material respects.

 

5.11.                     Licenses,
Permits, etc.

 

(a) The Company and the Subsidiaries own or
possess all licenses, permits, franchises, authorizations, patents, copyrights,
service marks,

 

37

 

trademarks and trade names, or rights thereto, that, individually or in
the aggregate, are Material, without known conflict with the rights of others.

 

(b) To the best knowledge of the Company, no product of the Company or any of its Subsidiaries infringes
in any Material respect on any license, permit, franchise, authorization, patent, copyright,
service mark, trademark, trade name or other right owned by any other Person.

 

(c) To the best knowledge of the Company, there is no Material
violation by any Person of any right of the Company or any of its Subsidiaries
with respect to any patent, copyright, service mark, trademark, trade name or
other right owned or used by the Company or any of its Subsidiaries.

 

5.12.                     Compliance
with ERISA.

 

(a) To the extent that the Company, or the ERISA Affiliates have
established US Plans, the Company, and the ERISA Affiliates have operated and
administered each US Plan in compliance with all applicable laws except for
such instances of noncompliance as have not resulted in and could not
reasonably be expected to result in a Material Adverse Effect.  Neither the Company nor any ERISA Affiliate
has incurred any liability pursuant to Title I or IV of ERISA or the penalty or
excise tax provisions of the US Tax Code relating to employee benefit plans (as
defined in Section 3 of ERISA), and no event, transaction or condition has
occurred or exists that could reasonably be expected to result in the
incurrence of any such liability by the Company or any ERISA Affiliate, or in
the imposition of any Lien on any of the rights, properties or assets of the
Company or any ERISA Affiliate, in either case pursuant to Title I or IV of
ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or
412 of the US Tax Code, other than such liabilities or Liens as would not be
individually or in the aggregate Material.

 

(b) The present value of the aggregate benefit liabilities under each
of the US Plans (other than US Multiemployer Plans), determined as of the

 

38

 

end of such US Plan’s most recently ended plan year on the basis of the
actuarial assumptions specified for funding purposes in such US Plan’s most
recent actuarial valuation report, did not exceed the aggregate current value
of the assets of such US Plan allocable to such benefit liabilities.  The term “benefit liabilities”  has the meaning specified in Section 4001
of ERISA and the terms “current value” and “present value” have the meaning specified in Section
3 of ERISA.

 

(c) The Company and the ERISA Affiliates have not incurred withdrawal
liabilities (and are not subject to contingent withdrawal liabilities) under
Section 4201 or 4204 of ERISA in respect of US Multiemployer Plans that
individually or in the aggregate are Material.

 

(d) The expected postretirement benefit obligation (determined as of
the last day of the Company’s most recently ended financial year in accordance
with United States of America Financial Accounting Standards Board Statement
No. 106, without regard to liabilities attributable to continuation coverage
mandated by Section 4980B of the US Tax Code) of the Company and its
Subsidiaries is not Material.

 

(e) The execution and delivery of the Existing Note Purchase Agreements
and of this Agreement, the issuance and sale of the Existing Notes on November
23, 1999 and the amendment and restatement of the Existing Notes pursuant to
this Agreement did not and does not involve any transaction that is or was
subject to the prohibitions of Section 406 of ERISA or in connection with which
a tax could be imposed pursuant to Section 4975(c)(1)(A)-(D) of the US Tax
Code.  The representation by the Company
in the immediately preceding sentence is made in reliance upon and subject to
the accuracy of the representation of each Noteholder in Section 6.2 as to the
sources of the funds used to pay the purchase price of the Existing Notes
purchased by such Noteholder.

 

(f) All Non-US Pension Plans have been established, operated,
administered and maintained in compliance with all laws, regulations and

 

39

 

orders applicable thereto except for such failures to comply, in the
aggregate for all such failures, that could not reasonably be expected to have
a Material Adverse Effect.  All
premiums, contributions and any other amounts required by applicable Non-US
Pension Plan documents or applicable laws have been paid or accrued as
required, except for premiums, contributions and amounts that, in the aggregate
for all such obligations, could not reasonably be expected to have a Material
Adverse Effect.

 

(g) The Company and the ERISA Affiliates are not under an obligation to
furnish a report to the Noteholders in accordance with Section 9.10 as a result
of any event or condition that has occurred or exists.

 

5.13.                     Existing
Financial Indebtedness;
Future Liens.

 

(a) Except as described therein, Schedule 5.13 sets forth a complete
and correct list of each item of outstanding Financial Indebtedness of the
Company and its Subsidiaries as of December 31, 2002 (which list specifies, as
to each such item of Financial Indebtedness, the collateral, if any, securing such Financial
Indebtedness), since which date there has been no (i) material increase in the
interest rates of such Financial Indebtedness, other than in accordance with
the terms thereof in effect as of December 31, 2002, (ii) increase in sinking
funds of such Financial Indebtedness, other than in accordance with the terms
thereof in effect as of December 31, 2002, (iii) increase in instalment
payments or reduction of maturities of such Financial Indebtedness (other than
in connection with a prepayment thereof as permitted by the terms and
provisions of the agreements and instruments governing such Financial
Indebtedness as in effect from time to time), or (iv) increase in amounts of
such Financial Indebtedness that otherwise would not be permitted under Section
10.6 and Section 10.7.  Neither the
Company nor any Subsidiary is in default, and no waiver of default is currently
in effect, in the payment of any principal or interest on any such Financial Indebtedness
of the Company or such Subsidiary and

 

40

 

no event or condition exists with respect to any such Financial
Indebtedness of the Company or any Subsidiary that would permit (or that with
notice or the lapse of time, or both, would permit) one or more Persons to
cause such Financial Indebtedness to become due and payable before its stated
maturity or before its regularly scheduled dates of payment (other than
mandatory prepayments or repurchases of Financial Indebtedness resulting from,
or arising in connection with, transactions that would be permitted by Section
10.2 and Section 10.4).

 

(b) Except as disclosed in Schedule 5.13, neither the Company nor any
Subsidiary has agreed or consented to cause or permit in the future (upon the
happening of a contingency or otherwise) any of its property, whether now owned
or hereafter acquired, to be subject to a Lien not permitted by Section 10.3.

 

5.14.                     Foreign Assets Control Regulations, etc.

 

(a) Neither the sale of the Existing Notes by the Company, its use of
the proceeds thereof, and the execution, delivery and performance of the
Existing Note Purchase Agreements violated, nor will the execution, delivery
and performance of this Agreement by the Company nor the amendment and
restatement of the Existing Notes pursuant to this Agreement violate, the
Trading with the Enemy Act of the United States of America, as amended, or any
of the foreign assets control regulations of the Treasury Department of the
United States of America (31 CFR, Subtitle B, Chapter V, as amended) or any
enabling legislation or executive order relating thereto.

 

(b) Neither the Company nor any Subsidiary is a Person or entity
described by Section 1 of Executive Order 13224 of September 23, 2001 Blocking
Property and Prohibiting Transactions With Persons Who Commit, Threaten to
Commit, or Support Terrorism, Exec. 
Order No. 13,224 66 Fed. Reg. 47,079 (2001), and neither the Company nor
any

 

41

 

Subsidiary is knowingly engaged in any dealings or transactions, or is
otherwise associated with any such Persons or entities in violation of such
Executive Order.

 

5.15.                     Status under Certain Statutes.

 

Neither the Company nor any Subsidiary is
subject to regulation under the Investment Company Act of 1940 of the United
States of America, as amended, the Public Utility Holding Company Act of 1935
of the United States of America, as amended, or the Federal Power Act of the
United States of America, as amended.

 

5.16.                     Environmental Matters.

 

(a) Neither the Company nor any Subsidiary has knowledge of any claim
or has received any notice of any claim, and no proceeding has been instituted
raising any claim against the Company or any of its Subsidiaries or any of
their respective real properties now or formerly owned, leased or operated by
any of them or other assets, alleging any damage to the environment or
violation of any applicable Environmental Laws, except, in each case, such as
could not reasonably be expected to result in a Material Adverse Effect.

 

(b) Neither the Company nor any of its Subsidiaries has knowledge of
any facts which would give rise to any claim, public or private, of violation
of applicable Environmental Laws or damage to the environment emanating from,
occurring on or in any way related to real properties now or formerly owned,
leased or operated by any of them or to other assets or their use, except, in
each case, such as could not reasonably be expected to result in a Material Adverse
Effect.

 

(c) Neither the Company nor any of its Subsidiaries has stored any
Hazardous Materials on real properties now or formerly owned, leased or
operated by any of them and has not disposed of any Hazardous Materials

 

42

 

in a manner contrary to any applicable
Environmental Laws in each case in any manner that could reasonably be expected
to result in a Material Adverse Effect.

 

(d) All buildings on all real properties now
owned, leased or operated by the Company or any of its Subsidiaries are in
compliance with applicable Environmental Laws, except where failure to comply
could not reasonably be expected to result in a Material Adverse Effect.

 

Pari Passu Ranking.

 

The Company’s obligations under the Financing
Documents rank at least pari passu, without preference or priority, with all of
its other outstanding obligations in respect of its senior, unsecured and
unsubordinated Financial Indebtedness, except for those obligations that are
mandatorily preferred by law and not by reason of contract.

 

5.18.                     Withholding Taxes.

 

Assuming that (a) each Noteholder is and will
be a resident of the United States of America for the purposes of the Double

Kingdom, dated 31st December, 1975 as may from time to time be amended,
re-enacted or replaced (the “US/UK Tax Treaty”), (b) the income each Noteholder receives under the Notes is not and

establishment, or to the performance of personal services through a fixed base,
in the United Kingdom, (c) the income each Noteholder receives under the Notes

Noteholder’s capital is and will be owned directly or indirectly by one or more
Persons who are not individual residents and not nationals of the United States
of America, (e) each Noteholder submits a validly completed and duly executed
United Kingdom Inland Revenue Form FD 13 to the IRS, and (f) the IRS certifies
on such Form FD 13 that each Noteholder is a corporation that has filed a
United States Corporation Income Tax Return as a domestic corporation for its
most recently

 

43

 

ended tax year for
which such return is required to be filed (giving effect to any applicable
extension) and such certified Form FD 13 is received from the IRS by the Inland
Revenue and the Inland Revenue certifies to the Company such Noteholder’s
entitlement to the benefit of the US / UK Tax Treaty prior to the first
interest payment date under the Notes, the Company will not be required to make
any deduction or withholding from any interest payment it may make to each
Noteholder under this Agreement or the Notes under the laws of the United
Kingdom or any jurisdiction or territory thereof as in effect on the date
hereof.

 

5.19.                     Solvency.

 

The fair value of the businesses and assets of the Company and each
Guarantor will be in excess of the amount that will be required to pay the
total liabilities of the Company or such Guarantor (including, without
limitation, contingent, subordinated, unmatured and unliquidated liabilities on
existing debts, as such liabilities may become absolute and matured), in each
case after giving effect to the transactions contemplated by this Agreement and
the other Financing Documents and the use of proceeds therefrom.  The Company and each Guarantor, after giving

Financing Documents and the use of the proceeds therefrom, will not be:

(e) or Section 123(2) of the Insolvency Act); or

 

(c) engaged in any business or transaction, or about to engage in any
business or transaction, for which the Company or such Guarantor has an
unreasonably small capital.

 

Neither the Company nor any Guarantor has any
intent to (i) hinder, delay or defraud any entity to which it is, or will
become, on or after the date hereof, indebted, or (ii) incur debts that would
be beyond its ability to pay as they mature.

 

44

 

5.20.                     No Event of Default.

 

Without prejudice to Section 1.6 hereof, on
Default or Event of Default (as each such term is defined in the Existing Note
Purchase Agreements) and no Default or Event of Default (as each such term is
defined in this Agreement) has occurred and is continuing.

 

6.                                      REPRESENTATIONS OF THE NOTEHOLDERS.

 

Each Noteholder represents that at least one
of the following statements is an accurate representation as to each source of
funds (a “Source”) used by it to acquire the Existing Notes:

 

(a) the Source was
an “insurance company general account” as defined in United States Department
of Labor Prohibited Transaction Exemption (“PTE”)
95-60 (60 FR 35925, July 12, 1995) and in respect thereof represents as at
November 23, 1999 that there was no “employee benefit plan” (as defined in
Section 3(3) of ERISA and Section 4975(e)(1) of the US Tax Code, treating as a
single plan all plans maintained by the same employer or employee organization
or affiliate thereof) with respect to which the amount of the general account
reserves and liabilities of all contracts held by or on behalf of such plan
exceeded 10% of the total reserves and liabilities of such general account
(exclusive of separate account liabilities) plus surplus, as set forth in the
NAIC Annual Statement then filed with its state of domicile; or

 

(b) if such
Noteholder was an insurance company, the Source did not include assets
allocated to any separate account maintained by it in which any employee
benefit plan (or its related trust) had any interest, other than a separate
account that was maintained solely in connection with its fixed contractual
obligations under which the amounts payable, or credited, to such plan and to
any participant or beneficiary of such plan (including any annuitant) were not
affected in any manner by the investment performance of the separate account;
or

 

45

 

(c) the Source was
either (i) an insurance company pooled separate account, within the meaning of
PTE 90-1 (issued January 29, 1990), or (ii) a bank collective investment fund,
within the meaning of PTE 91-38 (issued July 12, 1991) and, except as it had
disclosed to the Company in writing, no employee benefit plan or group of plans
maintained by the same employer or employee organization beneficially owned
more than 10% of all assets allocated to such pooled separate account or
collective investment fund; or

 

(d) the Source
constituted assets of an “investment fund” (within the meaning of Part V of the
QPAM Exemption) managed by a “qualified professional asset manager” or “QPAM”
(within the meaning of Part V of the QPAM Exemption), no employee benefit
plan’s assets that were included in such investment fund, when combined with
the assets of all other employee benefit plans established or maintained by the
same employer or employee benefit plans established or maintained by the same
employer or by an affiliate (within the meaning of section V(c(1) of the QPAM
Exemption) of such employer or by the same employee organization and managed by
such QPAM, exceeded 20% of the total client assets managed by such QPAM, the
conditions of Part I(c) and (g) of the QPAM Exemption were satisfied, neither
the QPAM nor a Person controlling or controlled by the QPAM (applying the
definition of “control” in section V(e) of the QPAM Exemption) owned a 5% or
more interest in the Company or any Guarantor; and

the Company shall have disclosed the nature of this Agreement, the Notes and
the obligations of the Company in respect thereto to such exchange and the
Company shall, if so requested by a holder of a Note, submit to such exchange
such factual submissions and other representations as such holder of a Note may
request in order to obtain confirmation from responsible officials of such
exchange that the disclosure of such information would require public
disclosure or is otherwise prohibited by the requirements of such exchange
unless such information is

 

61

 

publicly disclosed (provided that, notwithstanding the foregoing, where
the examination or inspection of such materials or information is being
requested at any time when a Default or an Event of Default then exists, (i)
the Company shall be obligated to disclose to the holders any such information
the disclosure of which would give rise to a disclosure obligation under the
rules or regulations of such exchange even if such disclosure would require the
Company or any Subsidiary to make public disclosure thereof to comply with such
rules and regulations, and (ii) in any case where such disclosure is prohibited
by law or by order or decree or by any agreement of confidentiality as
described in clause (a) above, the Company will use its best efforts to have
such prohibition removed or waived so as to permit the disclosure of such
materials or information to the holders of the Notes).  Notwithstanding anything herein to the
contrary, the Company shall be required to disclose, and shall procure that its
Subsidiaries shall disclose, all information (including, without limitation,
the information described in this Section 7.4) to the Noteholders that has been
disclosed or otherwise provided (in any manner whatsoever) directly or
indirectly to any lender under the Bank Facility Agreement, any Committed
Medium-Term Financing and/or a Committed External Financing.

8.3.                            Prepayments with Make-Whole Amount.

 

The Company may, at its option, upon notice
as provided below, prepay at any time all, or from time to time any part of,
the Notes, in an amount not less than 5% of the aggregate principal amount of
the Notes then outstanding in the case of a partial prepayment, at 100% of the
principal amount so prepaid plus the Make-Whole Amount determined for the
prepayment date with respect to such principal amount.  The Company will give each holder of Notes
written notice of each optional prepayment under this Section 8.3 not less than
30 days and not more than 60 days prior to the date fixed for such prepayment .
Each such notice shall specify such prepayment date, the aggregate principal
amount of the Notes and of each Series of Notes to be prepaid on such date, the
principal amount and Series of each Note held by such holder to be prepaid
(determined in accordance

 

65

 

with Section 8.4), and the interest to be paid on the prepayment date
with respect to such principal amount being prepaid, and shall be accompanied
by a certificate of Senior Officers of the Company as to the estimated
Make-Whole Amount due in connection with such prepayment (calculated as if the
date of such notice were the date of the prepayment), setting forth the details
of such computation.  Three Business
Days prior to such prepayment, the Company shall deliver to each holder of
Notes a certificate of Senior Officers of the Company specifying the
calculation of such Make-Whole Amount as of the specified prepayment date.

 

8.4.                            Allocation of Partial Optional
Prepayments.

 

In the case of each partial prepayment of the
Notes pursuant to Section 4.7(a) or Section 8.3, the principal amount of the
Notes to be prepaid shall be allocated among all of the Notes at the time
outstanding (without regard to Series) in proportion, as nearly as practicable,
to the respective unpaid principal amounts thereof not therefore called for
prepayment.

 

8.5.                            Maturity; Surrender, etc.

 

In the case of each prepayment of Notes
pursuant to Section 4.7(a), Section 8.3, Section 8.7 or Section 8.8, the
principal amount of each Note to be prepaid shall mature and become due and
payable on the date fixed for such prepayment, together with interest on such
principal amount accrued to such date and the applicable Make-Whole Amount or
Modified Make-Whole Amount, if any. 
From and after such date, unless the Company shall fail to pay such
principal amount when so due and payable, together with the interest and
Make-Whole Amount or Modified Make-Whole Amount, if any, as aforesaid, interest
on such principal amount shall cease to accrue.  Any note paid or prepaid in full pursuant to Section 8.3 shall be
surrendered to the Company and cancelled and shall not be reissued, and no Note
shall be issued in lieu of any prepaid principal amount of any Note.

 

66

 

8.6.                            Purchase of Notes.

 

The Company will not, nor will it permit any
Subsidiary or other Affiliate to, purchase, redeem, prepay or otherwise
acquire, directly or indirectly, any of the outstanding Notes except upon the
payment or prepayment of the Notes in accordance with the terms of this
Agreement and the Notes.  The Company
will promptly cancel all Notes acquired by it, any Subsidiary or any other
Affiliate pursuant to any payment or prepayment of Notes pursuant to any
provision of this Agreement and no Notes may be issued in substitution or
exchange for any such Notes.

 

8.7.                            Optional prepayment of Notes for Tax
Reasons.

 

If a Special Tax Event occurs and, by reason
thereof, the Company would, on the occasion of any interest payment in respect
of the Notes, become obligated to make Additional Payments in respect of such
payment of interest to one or more holders of Notes, the Company may give the
holders of all Notes in respect of which such Additional Payments are to be
made (such holders being referred to as the “Affected Holders”) irrevocable written notice (a “Tax Prepayment Notice”) of
the prepayment of all (but not less than all) of the Notes of all Affected
Holders not less than 30 nor more than 60 days prior to the prepayment date
specified in such notice, provided that the prepayment date is less than 18
months after the occurrence of such Special Tax Event, and provided further
that the Company will not give any Tax Prepayment Notice pursuant to this
Section 8.7 unless the aggregate of all Additional Payments then payable on all
Notes in respect of interest payments due within six months after such Tax Prepayment
Notice is equal to or exceeds 5% of the aggregate amount of such interest
payments on all Notes of all Affected Holders during such period.  Each Tax Prepayment Notice shall specify the
prepayment date and the circumstances giving rise to the Company’s obligation
to make Additional Payments and the amount thereof and stating that the Notes
of all Affected Holders shall be prepaid on that date at the principal amount
so to be prepaid, together with accrued interest thereon to the date fixed for such
prepayment, plus the Modified Make-Whole Amount for each such Note, unless, in
the case of any Affected Holder, such Affected Holder shall, by written notice
given to the Company no more than 20 days after receipt of the

 

67

 

Tax Prepayment Notice, reject such prepayment (a “Rejection Notice”).

 

The form of Rejection Notice shall accompany
the Tax Prepayment Notice and shall state that execution and delivery thereof
shall (a) terminate the Company’s right to prepay such Affected Holder’s Notes
by reason of the Tax Prepayment Notice, and (b) operate as a permanent waiver
of such Affected Holder’s right to receive the Additional Payments arising as a
result of the circumstances described in the Tax Prepayment Notice in respect
of all future payments of interest on such Affected Holder’s Notes (but not
such Affected Holder’s right to receive any Additional Payments which arise out
of payments made prior to the date of such proposed prepayment or by reason of circumstances
not described in the Tax Prepayment Notice or which exceed the amount of the
Additional Payments described in the Tax Prepayment Notice), which waiver shall
be binding upon all subsequent transferees of such Notes, and, upon request of
the Company and at its expense, such Affected Holder shall present each of its
Notes to the Company for the purpose of making a notation of such waiver
thereon.  The Tax Prepayment Notice
having been given as aforesaid to each Affected Holder, the principal amount of
all Notes specified therein, together with accrued interest thereon to the date
of such prepayment, plus such Modified Make-Whole Amount, shall become due and
payable on such prepayment date unless such Affected Holder shall timely give a
Rejection Notice as aforesaid or unless a Default or Event of Default shall
have occurred and be continuing on such prepayment date.  Three Business Days prior to such
prepayment, the Company shall deliver to each Affected Holder a certificate of
Senior Officers of the Company specifying the calculation of such Modified
Make-Whole Amount as of such specified prepayment date.  The provisions of this Section 8.7 shall not
be applicable (i) if the payment of the Additional Payments arises under
circumstances where the Taxing Jurisdiction under Section 22.1 is not the
United Kingdom and (ii) (A) if the obligation to pay Additional Payments arises
by reason of a merger of the Company permitted by Section 10.2 or other
analogous permitted transactions referred to in such Section or (B) where the
obligation to pay Additional Payments would not have arisen had the Company
made such payments through the United Kingdom.

 

68

 

8.8.                            Change in Control.

 

Immediately after the occurrence of a Change
in Control or a Control Event, the Company will give written notice thereof to
the holders of all outstanding Notes, which notice shall:

 

(a) refer specifically to this Section 8.8;

 

(b) describe the Change in Control or Control
Event in reasonable detail; and

 

(c) in the case that a Change in Control has
occurred:

 

(i)                                  contain
an offer to prepay all Notes at the price specified below on the date therein
specified (the “Change in Control Prepayment Date”), which shall be a Business Day not less than 30 nor more than 45 days
after the date of such notice;

 

(ii)                              specify
the Response Date (as defined below) in respect thereof; and

 

(iii)                          indicate
the Company’s estimate of the Make-Whole Amount with respect to such prepayment
(calculated as if the date of such notice were the date of prepayment).

 

Each holder of a Note shall notify the
Company of such holder’s acceptance or rejection of any such offer described in
clause (c) above by giving written notice (which shall be irrevocable) of such
acceptance or rejection to the Company at least 10 days prior to the Change in
Control Prepayment Date (the “Response Date”); provided, however, that the failure by the holder
of a Note to respond to such offer in writing on or before the Response Date
shall be deemed to be an acceptance of such offer in respect of such Change in
Control.  Three Business Days prior to
such payment, the Company shall deliver to each holder of Notes a certificate
of Senior Officers of the Company specifying the calculation of such Make-Whole
Amount as of the specified Change in Control Prepayment Date.  The Company

 

69

 

shall prepay on the Change in Control Prepayment Date all of the Notes
held by the holders as to which such offer has been so accepted, at the
principal amount of such Note, together with interest accrued thereon to the
Change in Control Prepayment Date, plus an amount equal to the Make-Whole
Amount with respect to such Note.  If
any holder shall reject such offer, such holder shall be deemed to have waived
its rights under this Section 8.8 to require prepayment of all Notes held by
such holder in respect of such Change in Control but not in respect of any
subsequent Change in Control.

 

Notwithstanding anything to the contrary in
this Section 8.8, to the extent that the Bank Facility, any Committed
Medium-Term Financing or any Committed External Financing is cancelled and
outstandings thereunder are declared to become due and payable thereunder or
are required to be repaid in connection with a Control Event or a Change in
Control (the “Bank
Control Payment Date”) prior to
the Change in Control Prepayment Date, irrespective of whether such Bank
Control Payment Date is prior to the Response Date or prior to the date on
which the Company gives notice of a Change of Control or a Control Event to the
holders of all outstanding Notes, the Change in Control Payment Date shall be
deemed to be such Bank Control Payment Date and the failure by any holder of a
Note to respond to any offer (if any) to prepay on or before such date shall be
deemed an acceptance of such offer in respect of such Change of Control or
Control Event.

 

8.9.                            Make-Whole Amount; Modified Make-Whole
Amount.

 

The term “Make-Whole Amount” means, with respect to any Note of any Series, an amount equal to the
excess, if any, of the Discounted Value of the Remaining Scheduled Payments
with respect to the Called Principal of such Note of such Series over the
amount of such Called Principal, provided that the Make-Whole Amount may in no
event be less than zero. For the purposes of determining the Make-Whole Amount,
the following terms have the following meanings:

 

“Called
Principal” means, with respect to any Note of any Series, the
principal of such Note that is to be prepaid pursuant to Section 4.7(a),

 

70

 

 

Section 8.3, Section 8.7 or Section 8.8 or
has become or is declared to be immediately due and payable pursuant to Section
12.1, as the context requires.

 

“Discounted Value” means, with respect to the Called Principal of any
Note of any Series, the amount obtained by discounting all Remaining Scheduled
Payments with respect to such Called Principal from their respective scheduled
due dates to the Settlement Date with respect to such Called Principal, in
accordance with accepted financial practice and at a discount factor (applied
on the same periodic basis as that on which interest on such Series of Notes is
payable) equal to the Reinvestment Yield with respect to such Called Principal.

 

“Reinvestment Yield”
means, with respect to the Called Principal of any Note of any Series, 0.50%
over the yield to maturity implied by (a) the yields reported, as of 10:00 A.M.
(New York City time) on the third Business Day preceding the Settlement Date
with respect to such Called Principal, on the display designated as “Page PX1” on
the Bloomberg Financial Markets Commodities News (or such other display as may
replace Page PX1 on the Bloomberg Financial Markets Commodities News) for
“on-the-run” U.S.  Treasury securities
having a maturity equal to the Remaining Average Life of such Called Principal
as of such Settlement Date, or (b) if such yields are not reported as of such
time or the yields reported as of such time are not ascertainable, the Treasury
Constant Maturity Series Yields reported, for the latest day for which such
yields have been so reported as of the third Business Day preceding the
Settlement Date with respect to such Called Principal, in Federal Reserve
Statistical Release H.15 (519) (or any comparable successor publication) for
“on-the-run” U.S. Treasury securities having a constant maturity equal to the
Remaining Average Life of such Called Principal as of such Settlement Date.
Such implied yield will be determined, if necessary, by (i) converting U.S.
Treasury bill quotations to bond-equivalent yields in accordance with accepted
financial practice, and (ii) interpolating linearly between (x) the
“on-the-run” U.S. Treasury security with the remaining life closest to and

 

71

 

greater than the Remaining Average Life, and (y) the
“on-the-run” U.S. Treasury security with the remaining life closest to and less
than the Remaining Average Life.

 

“Remaining
Average Life” means, with respect to any Called Principal of any
Series of Notes, the number of years (calculated to the nearest one-twelfth
year) obtained by dividing (x) such Called Principal into (y) the sum of the
products obtained by multiplying (a) the principal component of each Remaining
Scheduled Payment with respect to such Called Principal by (b) the number of
years (calculated to the nearest one-twelfth year) that will elapse between the
Settlement Date with respect to such Called Principal and the scheduled due
date of such Remaining Scheduled Payment.

 

“Remaining
Scheduled Payments” means, with respect to the Called Principal of any
Note of any Series, all payments of such Called Principal and interest thereon
that would be due after the Settlement Date with respect to such Called
Principal if no payment of such Called Principal were made prior to its
scheduled due date, provided that if such Settlement Date is not a date on
which interest payments are due to be made under the terms of the Notes of such
Series, then the amount of the next succeeding scheduled interest payment will
be reduced by the amount of interest accrued to such Settlement Date and
required to be paid on such Settlement Date Pursuant to Section 4.7(a), Section
8.3, Section 8.7, Section 8.8 or Section 12.1.

 

“Settlement
Date” means, with respect to the Called Principal of any
Note of any Series, the date on which such Called Principal is to be prepaid
pursuant to Section 4.7(a), Section 8.3, Section 8.7 or Section 8.8 or has
become or is declared to be immediately due and payable pursuant to Section
12.1, as the context requires.

 

The term “Modified Make-Whole Amount” means, with
respect to any Note of any Series, the Make-Whole Amount therefor calculated on
the basis of a

 

72

 

“Reinvestment Yield” in which a spread of “0.75%” has been substituted for
a spread of “0.50%”.

 

The Make-Whole Amount and Modified Make-Whole
Amount shall be calculated for any prepayment or repayment of the Notes based
on the interest rate, interest payment and maturity date as set forth in the
Existing Notes and the Existing Note Purchase Agreements in each case as in
effect immediately prior to the Effective Date.

 

The Company acknowledges, and the parties
hereto agree, that the right of each holder to have maintained its investment
in the Notes to the maturity date thereof free from prepayment by the Company
is a valuable right and that the provision for the payment of a Make-Whole
Amount and Modified Make-Whole Amount by the Company, in the event that the
Notes are prepaid under the terms of this Agreement or are accelerated as a
result of an Event of Default, is intended to provide compensation for the
deprivation of such right in connection with the circumstances under which the
transactions contemplated by this Agreement (including, without limitation, the
Restructuring Transaction) have been agreed and under any circumstances arising
out of an Event of Default.

 

9.                                      AFFIRMATIVE COVENANTS.

 

The Company covenants
that so long as any of the Notes are outstanding:

 

9.1.                            Compliance with Law.

 

The Company will and will cause each member
of the Group to comply with all laws, ordinances or governmental rules or
regulations to which each of them is subject, including, without limitation, Environmental
Laws, and will obtain, maintain in effect and comply with all licenses,
certificates, permits, franchises, consents and other governmental
authorizations required under any such applicable law, ordinance, governmental
rule or regulation or which is necessary to the operation and ownership of
their respective properties or to the conduct of their respective businesses,
in each case to the extent necessary to ensure that non-compliance

 

73

 

with such laws, ordinances or governmental rules or regulations or the
failure to obtain or maintain in effect such licenses, certificates, permits,
franchises, consents and other governmental authorizations could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.  The Company will
promptly upon the request of any Noteholder provide such Noteholder with
certified copies of all such material licenses, certificates, permits, franchises,
consents and other governmental authorizations as may be required under any
applicable law or regulation to enable the Company to perform its obligations
under, or for the validity or enforceability of, any Financing Document.

 

9.2.                            Insurance.

 

The Company will and will cause each of the Material
Subsidiaries to maintain, with financially sound and reputable insurers, such
insurance with respect to their respective properties and businesses against
such casualties and contingencies, of such types, on such terms and in such
amounts (including deductibles, co-insurance and self-insurance, if adequate
reserves are maintained with respect thereto) as is customary in the case of
entities of established reputations engaged in the same or a similar business
and similarly situated.

 

9.3.                            Maintenance of Properties.

 

The Company will and will cause each of the
Material Subsidiaries to maintain and keep, or cause to be maintained and kept,
their respective properties in good repair, working order and condition (other
than ordinary wear and tear), so that the business carried on in connection
therewith may be properly conducted at all times, provided that this Section
9.3 shall not prevent the Company or any Material Subsidiary from discontinuing
the operation and the maintenance of any of its properties if such
discontinuance is desirable in the conduct of its business and the Company has
concluded that such discontinuance could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

 

74

 

9.4.                            Payment of Taxes
and Claims.

 

The Company will and will cause each of the
Material Subsidiaries to file all income and other Material tax returns
required to be filed in any jurisdiction and to pay and discharge all taxes
shown to be due and payable on such returns and all other taxes, assessments,
governmental charges, or levies imposed on them or any of their properties,
assets, income or franchises, to the extent such taxes and assessments have
become due and payable and before they have become delinquent, and all claims
for which sums have become due and payable that have or might become a Lien on
properties or assets of the Company or any Material Subsidiary, provided that
neither the Company nor any Material Subsidiary need pay any such tax or
assessment or claims if (a) the amount, applicability or validity thereof is
contested by the Company or such Material Subsidiary on a timely basis in good
faith and in appropriate proceedings, and the Company or such Material Subsidiary
has established adequate reserves or provisions therefor in accordance with,
and to the extent required by, Applicable GAAP on the books of the Company or
such Material Subsidiary, or (b) the nonpayment of all such taxes, assessments
and claims in the aggregate could not reasonably be expected to have a Material
Adverse Effect.

 

9.5.                            Corporate Existence, etc.

 

Subject to Section 10.2, the Company will at
all times preserve and keep in full force and effect its corporate
existence.  Subject to Section 10.2 and
Section 10.4, the Company will at all times preserve and keep in full force and
effect the corporate existence of each of its Material Subsidiaries and all
rights and franchises of the Company and its Material Subsidiaries unless, in

transfer or lease all or substantially all of its properties in a single
transaction or series of transactions to, the Company or any other Subsidiary
(including, without limitation, a Person which becomes a Subsidiary in
connection with such transaction or series of transactions), so long as the
Company shall have at least the same degree of Control with respect to the
Subsidiary which survives such consolidation, amalgamation, or merger or the
corporation that purchases, leases or otherwise acquires all or substantially
all of the properties of such Subsidiary as it had with respect to the first
Subsidiary, (y) convey, transfer or lease all or substantially all of its
properties (or consolidate, merge or amalgamate with another Person if the sole
purpose of such transaction is to effect the disposition, directly or
indirectly, of such Subsidiary by the Company) in compliance with Section 10.4
or (z) reorganize on a solvent basis where all of the assets of such Subsidiary
remain within the Group, so long as the Company shall have at least the same
degree of Control with respect to the Subsidiaries which acquire all or

to the first Subsidiary), provided that the foregoing restriction does not
apply to the consolidation, merger or amalgamation of the Company or a
Guarantor with, or the conveyance, transfer or lease of all or substantially
all of the properties of the Company or a Guarantor in a single transaction or
series of transactions to, any Person (a  “Permitted
Reorganization”) so long as:

 

(a) the successor formed by such
consolidation or amalgamation or the survivor of such merger or the Person that
acquires by conveyance, transfer or lease all or substantially all of the
properties of the Company or such Guarantor as an entirety, as the case may be
(the “Successor

corporation organized and existing under the laws of an Acceptable State;

 

(b) if the Company or such Guarantor is not
the Successor Corporation, as the case may be, then the Successor Corporation
shall have executed and

 

80

 

delivered to each holder of Notes its
assumption of the due and punctual performance and observance of each covenant
and condition of the Company contained in this Agreement and the Notes, or, in
the case of a Guarantor, contained in the applicable Subsidiary Guarantee (in
each case pursuant to such agreements and instruments as shall be reasonably
satisfactory to the Required Holders), and the Company or such Guarantor, as
the case may be, shall have caused to be delivered to each holder of Notes:

 

(i)                                  an
opinion of internationally recognized independent counsel, or other independent
counsel reasonably satisfactory to the Required Holders, to the effect that all
agreements or instruments effecting such assumption are enforceable in
accordance with their terms and comply with the terms hereof; and

 

(ii)                              an
opinion of independent counsel in the jurisdiction of organization of such
Successor Corporation reasonably satisfactory in form and substance to the
Required Holders to the effect that (1) the Successor Corporation is duly and
validly organized and existing under the laws of such jurisdiction of
organization, (2) the Successor Corporation shall have duly authorized,
executed and delivered such agreements effecting such assumption, and such
agreements are, subject to the legality and enforceability thereof under New
York law, legally binding and enforceable in accordance with their terms under
the laws of such jurisdiction, (3) such assumption does not conflict with the
laws of such jurisdiction, and (4) the obligations of such Successor
Corporation rank at least pari passu with all of such Successor Corporation’s
other obligations in respect of its senior, unsecured and unsubordinated
Financial Indebtedness (except for such obligations as shall be mandatorily preferred
by law and not by reason of contract);

 

(c) immediately after giving effect to such
transaction, no Default or Event of Default shall have occurred and be
continuing; and

 

81

 

(d) in the case of any such transaction
involving the Company, the Company shall have complied with the provisions of
Section 8.8 to the extent such Section is applicable in connection with such
transaction.

 

Notwithstanding the foregoing, no such
conveyance, transfer or lease of all or substantially all of the properties of
the Company or any Guarantor shall have the effect of releasing the Company,
any Guarantor or any Successor Corporation that shall theretofore have become
such in the manner prescribed in this Section 10.2 from its liability under
this Agreement or the Notes or its respective Subsidiary Guarantee, as the case
may be.

of its Subsidiaries to, directly or indirectly create, incur, assume or permit
to exist (upon the happening of a contingency or otherwise) any Lien on or with
respect to any property or asset (including, without limitation, any document
or instrument in respect of goods or accounts receivable) of the Company or any
such Subsidiary (and in no event shall any amounts outstanding under the Bank
Facility, any Committed Medium-Term Financing or any Committed External
Financing be secured by any Liens) whether now owned or hereafter acquired, or
any income or profits therefrom or assign or otherwise convey any right to
receive income or profits unless it makes, or causes to be made, effective
provision whereby the Notes will be equally and ratably secured with any and
all other obligations thereby secured, (x) such security to be granted (i) no
later than the date upon which the Lien is granted, and (ii) pursuant to an
agreement reasonably satisfactory to the Required Holders and (y) if such
obligations are the Bank Facility, any Committed Medium-Term Financing or any
Committed External Financing, the holders of such obligations shall have
entered into an intercreditor agreement with the Noteholders satisfactory in
form, scope and substance to each Noteholder in its sole discretion and, in any
case, the Notes shall have the benefit to the fullest extent that, and with
such priority as, the holders of the Notes may be entitled under applicable
law, of an equitable Lien on such property, except:

 

82

 

(a) Liens existing as of December 31, 2002 and

Subsidiary in favor of the Company or another Wholly-Owned Subsidiary;

acquired, consolidated or merged (and not incurred in anticipation thereof), or
in the case of any property or assets acquired by the Company or any Subsidiary
after the date hereof, Liens existing on such property or assets at the time of

any Lien permitted by clause (a) or (k) of this Section 10.3 in connection with

thereby (including the undrawn portion of facilities set forth in Schedule

facility is not increased and such Lien as so extended, renewed or replaced
does not extend to or cover any property other than the property covered
thereby immediately prior to such extension, renewal or replacement; and

 

(m) other Liens to the extent not otherwise

create, creates or permits to subsist any Lien on any of its assets in
violation of the preceding sentence, the Company shall ensure, by no later than
the date on which such Lien is granted, that (x) the relevant member of the
Group executes such security and intercreditor documentation as the Required
Holders may require to ensure that all the obligations under the Financing
Documents shall be secured by the same assets and shall rank pari passu with
the other obligations secured on those assets, or (y) at the request of the
Company, such other security and intercreditor documentation in respect of any
other assets of the Group as the Required Holders shall agree, provided that in
the case of both (x) and (y) such violation shall nevertheless constitute an
Event of Default.

(D)                             a

and validly organized and existing under the laws of its jurisdiction of

will not permit any Subsidiary (other than a
Subsidiary that is a Guarantor) to enter into, incur, grant or be or become
liable under or otherwise permit to exist any Guaranty in respect of any
Financial Indebtedness (other than the Financial Indebtedness evidenced by the
Notes and derivative transactions on standard ISDA terms), unless a Subsidiary
Guarantee has been granted by such Subsidiary in favor of the holders of the
Notes in respect of the obligations of the Company under and pursuant to this
Agreement and the Notes and such Subsidiary has otherwise complied with the
provisions of clause (b) of this Section 10.7.

 

(e) Pari
Passu Ranking.  Each
Subsidiary Guarantee will at all times rank at least pari passu, without
preference or priority, with any Guaranty granted by the Company or any
Subsidiary in respect of the Bank Facility, any Committed Medium-Term Financing
or any Committed External Financing.

 

10.8.                     No Restrictive Agreements.

 

The Company will not permit any Subsidiary
(other than a Guarantor) to become or remain a party to any agreement or
arrangement that prohibits or would prohibit or restrict such Subsidiary from
paying dividends or other distributions on its capital stock or other equity
interests or otherwise making advances to the Company or any other Subsidiary
if such agreement or arrangement would have a Material Adverse Effect.

 

10.9.                     Business of the Company and its
Subsidiaries.

 

The Company shall procure that, except as
disclosed to the Noteholders prior to the date hereof and in the Information

nature of the Group’s business from that carried on at the date of disclosure.

 

91

 

10.10.              Distributions.

 

(a) Distributions
prior to the Normalization Date. Prior to the Normalization Date,
the Company will not, and will not permit any Guarantor (except for the
Guarantors listed on Schedule 10.10 which are not Wholly-Owned Subsidiaries) to
declare (including, without limitation, by way of set-off, combination of
accounts or otherwise), make, pay or permit to accrue any Distribution (whether
in cash or in specie), provided that the Company or any Guarantor may declare
or permit to accrue a Distribution to the Company or another Guarantor, as the
case may be.

 

(b) Distributions
on and after the Normalization Date.  On and after the Normalization Date, the Company (i) may declare,
make, pay or permit to accrue a Distribution only if such Distribution is
directly derived from Net Distributable Earnings of the Company which accrued
after January 1, 2003, and (ii) will not permit any Guarantor (except for the
Guarantors listed on Schedule 10.10 
which are not Wholly-Owned Subsidiaries) to declare (including, without
limitation, by way of set-off, combination of accounts or otherwise) make, pay
or permit to accrue any Distribution (whether in cash or in specie), provided
that any Guarantor may declare or permit to accrue a Distribution to the
Company or another Guarantor, as the case may be.

 

10.11.              Acquisitions.

 

(a) Acquisitions
prior to the Normalization Date. Prior to the Normalization Date,
the Company will not, and will not permit any of its Subsidiaries to, acquire
or make any investment in any companies, joint ventures or partnerships or
other Persons or acquire any businesses (or interests therein) or incorporate
any company (or commit to do any of the same (whether conditionally or
otherwise)) (an “Acquisition”) whether for cash, shares or other consideration
without the prior written consent of the Required Holders except:

 

(i)                                  Acquisitions
of assets purchased in the ordinary course of

 

92

 

trade in connection with the Group’s current
businesses;

 

(ii)                              Permitted
Reorganizations;

 

(iii)                          The
payment of the existing deferred consideration obligations in respect of
Acquisitions completed prior to the Effective Date as set out on Schedule
10.11, which obligations shall be satisfied by the Company in Company shares to
the extent contemplated or expressly permitted by the agreements giving rise to
such obligations and which obligations the Company shall not modify or amend in
a manner that increases the amount payable by any member of the Group
thereunder or is otherwise less favorable to the Group except as further
described on Schedule 10.11; and

 

(iv) Acquisitions with an aggregate
consideration of up to £2,500,000 in any financial year.

 

(b) Acquisitions
on and after the Normalization Date. On and after the Normalization
Date, the Company will not, and will not permit any of its Subsidiaries to,
make an Acquisition or commit to make an Acquisition whether for cash, shares
or other consideration unless the group finance director of the Company
certifies to the holders of the Notes that such Acquisition would not on a pro
forma basis have resulted in the Company breaching any of the financial
covenants set out in this Agreement (and as in effect on and after the
Normalization Date) on either of (i) the two Testing Dates immediately prior to
and (ii) the two Testing Dates (based on the Company’s projections) immediately
after the proposed date of the Acquisition. 
For the purpose of calculating pro forma financial information for
purposes of this Section 10.11(b) for a period ending on a Testing Date, it
shall be assumed that the Acquisition shall have occurred on the first day of
the Accounting Period (which for the avoidance of doubt shall be a twelve month
period) ending on the applicable Testing Date.

 

Notwithstanding the foregoing, the Company
will not, and will not permit

 

93

 

any of its Subsidiaries to, make any Acquisition (except pursuant to
clause (a)(i) or clause (a)(iii) above) during the continuance of an Event of
Default under this Agreement whether before or after the Normalization Date.

 

10.12.     Maintenance of Most Favored Lender
Status.

 

Neither the Company nor any Guarantor will
(i) enter into any modification or amendment to any existing credit facility or
other financing document for Financial Indebtedness (including, without
limitation, the Bank Facility) other than any modification or amendment to any
existing derivative transaction on standard ISDA terms, or (ii) enter into any
new credit facility or financing document for Financial Indebtedness
(including, without limitation, any Committed Medium-Term Financing or
Committed External Financing) other than derivative transactions on standard
ISDA terms, that contains financial or other business covenants, definitions or
testing requirements relating thereto, guarantees, preferences,
representations, warranties, financial reporting requirements, defaults or
events of default (howsoever described) provisions more favorable to the lender
or financier thereunder than those applicable to the Notes (the “Additional Provisions”) unless the Company or the Guarantor, as applicable,
shall execute and deliver to the holders of the Notes an instrument in writing
supplementing the Financing Documents and extending the benefit of such
Additional Provisions to the holders of the Notes. Once incorporated in the
Financing Documents, no waiver or consent under or amendment or termination of
the credit facility or other financing document for Financial Indebtedness
containing the Additional Provisions shall have any effect on the Additional
Provisions as incorporated in the Financing Documents.

12.          REMEDIES ON DEFAULT, ETC.

 

12.1.       Acceleration.

 

(a) If an Event of
Default with respect to the Company or any Guarantor described in clause (g),
clause (h) or clause (m) of Section 11 (other than an Event of Default
described in sub-clause (ii) of clause (g) or described in sub-clause (vii) of
clause (g) by virtue of the fact that such clause encompasses sub-clause (ii)
of clause (g)) has occurred, all the Notes then outstanding shall automatically
become immediately due and payable.

 

(b) If any other
Event of Default has occurred and is continuing, any holder or holders of at
least 51% in principal amount of Notes at the time outstanding may at any time
at its or their option, by notice or notices to the Company, declare all the
Notes then outstanding to be immediately due and payable.

 

(c) If any Event of
Default described in clause (a) or clause (b) of Section 11 has occurred and is
continuing, any holder or holders of Notes at the time outstanding affected by
such Event of Default may at any time, at its or their option, by notice or
notices to the Company, declare all the Notes held by it or them to be
immediately due and payable.

 

Upon any Notes becoming due and payable under
this Section 12.1, whether automatically or by declaration, such Notes will
forthwith mature and the entire unpaid principal amount of such Notes, plus (x)
all accrued and unpaid

 

102

 

interest thereon and (y) the Make-Whole
Amount determined in respect of such principal amount (to the full extent
permitted by applicable law), shall all be immediately due and payable, in each
and every case without presentment, demand, protest or further notice, all of
which are hereby waived.  The Company
acknowledges, and the parties hereto agree, that each holder of a Note has the
right to maintain its investment in the Notes free from repayment by the
Company (except as herein specifically provided for) and that the provision for
payment of a Make-Whole Amount by the Company, in the event that the Notes are
prepaid or are accelerated as a result of an Event of Default, is intended to
provide compensation for the deprivation of such right under such circumstances.

 

12.2.    Other Remedies.

 

If any Default or Event of Default has
occurred and is continuing, and irrespective of whether any Notes have become
or have been declared immediately due and payable under Section 12.1, the
holder of any Note at the time outstanding may proceed to protect and enforce
the rights of such holder by an action at law, suit in equity or other
appropriate proceeding, whether for the specific performance of any agreement
contained herein or in any Note, or for an injunction against a violation of
any of the terms hereof or thereof, or in aid of the exercise of any power
granted hereby or thereby or by law or otherwise.

 

12.3.    Rescission.

 

At any time after any Notes have been
declared due and payable:

 

(a) pursuant to, and as provided in, clause
(b) of Section 12.1, any holder or holders of more than 50% in principal amount
of the Notes at the time outstanding may; or

 

(b) pursuant to, and as provided in, clause
(c) of Section 12.1, the holder or holders of such Notes that have declared
such Notes to be due and payable because of an Event of Default described in
clause (a) or clause (b) of Section 11 may,

 

103

 

by written notice to the Company, rescind and
annul any such declaration and its consequences if (i) the Company has paid all
overdue interest on the Notes, all principal of and Make-Whole Amount or
Modified Make-Whole Amount, if any, on any Notes that are due and payable and
are unpaid other than by reason of such declaration, and all interest on such
overdue principal and Make-Whole Amount or Modified Make-Whole Amount, if any,
and (to the extent permitted by applicable law) any overdue interest in respect
of any Series of the Notes, at the Default Rate for such Series, (ii) all Events
of Default and Defaults, other than non-payment of amounts that have become due
solely by reason of such declaration, have been cured or have been waived
pursuant to Section 17, and (iii) no judgment or decree has been entered for
the payment of any monies due pursuant hereto or to the Notes. No rescission
and annulment under this Section 12.3 will extend to or affect any subsequent
Event of Default or Default or impair any right consequent thereon.

 

12.4.    No Waivers or Election of Remedies,
Expenses, etc.

 

No course of dealing and no delay on the part
of any holder of any Note in exercising any right, power or remedy shall
operate as a waiver thereof or otherwise prejudice such holder’s rights, powers
or remedies.  No right, power or remedy
conferred by this Agreement or by any Note upon any holder thereof shall be
exclusive of any other right, power or remedy referred to herein or therein or
now or hereafter available at law, in equity, by statute or otherwise.  Without limiting the obligations of the
Company under Section 15, the Company will pay to the holder of each Note on
demand such further amount as shall be sufficient to cover all costs and
expenses of such holder incurred in any enforcement or collection under this
Section 12, including, without limitation, reasonable attorneys’, solicitors’
and barristers’ fees, expenses and disbursements.

 

104

The Company shall keep at its principal
executive office a register for the registration and registration of transfers
of Notes.  The name and address of each
holder of one or more Notes, each transfer thereof and the name and address of
each transferee of one or more Notes shall be registered in such register.  Prior to due presentment for registration of
transfer, the Person in whose name any Note shall be registered shall be deemed
and treated as the owner and holder thereof for all purposes hereof, and the
Company shall not be affected by any notice or knowledge to the contrary.  The Company shall give to any holder of a
Note that is an Institutional Investor promptly upon request therefor, a
complete and correct copy of the names and addresses of all registered holders
of Notes.

 

13.2.    Transfer and Exchange of Notes.

 

Upon surrender of any Note at the principal executive office of the
Company for registration of transfer or exchange (and in the case of a
surrender for registration of transfer, duly endorsed or accompanied by a
written instrument of transfer duly executed by the registered holder of such
Note or his attorney duly authorized in writing and accompanied by the address
for notices of each transferee of such Note or part thereof), the Company shall
execute and deliver within 10 Business Days, at the Company’s expense (except
as provided below), one or more new Notes of the same Series (as requested by
the holder thereof) in exchange therefor, in an aggregate principal amount
equal to the unpaid principal amount of the surrendered Note.  Each such new Note shall be payable to such
Person as such holder may request and shall be substantially in the form of
Note for such Series set forth in Exhibit 2.1(a), Exhibit 2.1(b), Exhibit
2.1(c) or Exhibit 2.1(d), as the case may be.  Each such new Note shall be dated and bear interest from the date
to which interest shall have been paid on the surrendered Note or dated the
date of the surrendered Note if no interest shall have been paid thereon.  The Company may require payment of a sum
sufficient to cover any stamp tax or governmental charge imposed in respect of
any such transfer of Notes.  Notes shall
not be transferred in denominations of less than US$500,000, provided that if
necessary to enable the registration of transfer by a holder of its entire
holding of Notes, one Note may be in a denomination of less than
US$500,000.  Any

 

105

 

transferee, by its acceptance of a Note registered in its name (or the
name of its nominee), shall be deemed to have made the representation set forth
in Section 6.

 

13.3.    Replacement of Notes.

 

Upon receipt by the Company of evidence
reasonably satisfactory to it of the ownership of and the loss, theft,
destruction or mutilation of any Note (which evidence shall be, in the case of
an Institutional Investor, notice from such Institutional Investor of such
ownership and such loss, theft, destruction or mutilation), and:

 

(a) in the case of loss, theft or
destruction, of indemnity reasonably satisfactory to it (provided that if the
holder of such Note is a Noteholder which is a party to this Agreement or a
nominee for any such Noteholder, or another holder of a Note with a minimum net
worth of at least US$50,000,000, such Person’s own unsecured agreement of
indemnity shall be deemed to be satisfactory); or

 

(b) in the case of mutilation, upon surrender
and cancellation thereof,

 

the Company at its own expense shall execute
and deliver within 10 Business Days, in lieu thereof, a new Note of the same Series,
dated and bearing interest from the date to which interest shall have been paid
on such lost, stolen, destroyed or mutilated Note or dated the date of such
lost, stolen, destroyed or mutilated Note if no interest shall have been paid
thereon.

 

14.                               PAYMENTS ON NOTES.

 

14.1.    Place of Payment.

 

Subject to Section 14.2, payments of principal, Make-Whole Amount, or
Modified Make-Whole Amount, if any, Additional Payments, if any, and interest
becoming due and payable on the Notes shall be made in New York, New York, USA
at the principal office of HSBC Bank USA, New York in such jurisdiction.

 

106

 

The Company may at any time, by notice to each holder of a Note, change
the place of payment of the Notes so long as such place of payment shall be
either the principal office of the Company in such jurisdiction or the
principal office of a bank or trust company in such jurisdiction.

 

14.2.            Home Office Payment.

 

So long as any Noteholder identified in
Schedule A to this Agreement or its nominee shall be the holder of any Note,
and notwithstanding anything contained in Section 14.1 or in such Note to the
contrary, the Company will pay all sums becoming due on such Note for
principal, Make-Whole Amount or Modified Make-Whole Amount, if any, Additional
Payments, if any, and interest by the method and at the address specified for
such purpose below such Noteholder’s name in Schedule A, or by such other
method or at such other address as such Noteholder shall have from time to time
specified to the Company in writing for such purpose, without the presentation
or surrender of such Note or the making of any notation thereon, except that
upon written request of the Company made concurrently with or reasonably
promptly after payment or prepayment in full of any Note, such Noteholder shall
surrender such Note for cancellation, reasonably promptly after any such
request, to the Company at its principal executive office or at the place of
payment most recently designated by the Company pursuant to Section 14.1. Prior
to any sale or other disposition of any Note held by a Noteholder or its
nominee such Noteholder will, at its election, either endorse thereon the
amount of principal paid thereon and the last date to which interest has been
paid thereon or surrender such Note to the Company in exchange for a new Note
or Notes pursuant to Section 13.2.  The
Company will afford the benefits of this Section 14.2 to any Institutional
Investor that is the direct or indirect transferee of any Note purchased by a
Noteholder under this Agreement and that has made the same agreement relating
to such Note as such Noteholder have made in this Section 14.2.

 

 

107

 

14.3.            Currency of Payment.

 

All payments under this Agreement and the Notes shall be made in US
Dollars.  To the fullest extent
permitted by applicable law, the obligation of the Company in respect of any
amount due under or in respect of this Agreement and the Notes, notwithstanding
any payment in any currency other than US Dollars, whether as a result of (i)
any judgment or order or the enforcement thereof, (ii) the realization on any
security, (iii) the liquidation of the Company or any Guarantor, (iv) any
voluntary payment by the Company or any Guarantor or (v) any other reason,
shall be discharged only to the extent of the amount in US Dollars that each
holder of Notes entitled to receive such payment may, in accordance with normal
banking procedures, purchase in the foreign exchange markets in London, England
with the sum paid in such other currency (after any premium and costs of
exchange) on the Business Day immediately following the day on which such
holder receives such payment and, if the amount in US Dollars that may be so
purchased for any reason is less than the amount originally due, the Company
shall indemnify and save harmless such holder from and against all loss or
damage arising out of or as a result of such deficiency.  This indemnity shall constitute an
obligation separate and independent from the other obligations contained in
this Agreement and the Notes, shall give rise to a separate and independent
cause of action, shall apply irrespective of any indulgence granted by such
holder from time to time and shall continue in full force and effect
notwithstanding any judgment or order for a liquidated sum in respect of an
amount due under this Agreement or the Notes or under any judgment or order.

 

15.                               EXPENSES, ETC.

 

15.1.            Transaction Expenses.

 

Whether or not the transactions contemplated
hereby are consummated, the Company will pay all costs and expenses (including,
without limitation, reasonable attorneys’ fees of a special United States
counsel and a special English counsel and, if reasonably required, other local
counsel) incurred by each holder of a Note in connection with such transactions
and in connection with any amendments, waivers or consents under or in respect
of this Agreement or the

 

108

 

Notes (whether or not such amendment, waiver or consent becomes
effective), including, without limitation: (a) the costs and expenses incurred
in enforcing or defending (or determining whether or how to enforce or defend)
any rights under this Agreement, the Notes or the Guarantees or in responding
to any subpoena or other legal process or informal investigative demand issued
in connection with this Agreement, the Notes or the Guarantees, or by reason of
being a holder of any Note; and (b) the costs and expenses, including, without limitation,
financial advisors’ and reporting or investigating accountants’ fees, incurred
in connection with the insolvency or bankruptcy of the Company or any
Subsidiary or in connection with any work-out or restructuring of the
transactions contemplated hereby and by the Notes and by the Guarantees.  The Company will pay, and will save each
holder of a Note and hold each holder of a Note harmless from, all claims in
respect of any fees, costs or expenses if any, of brokers and finders (other
than those retained by such Noteholder).

 

15.2.            Survival.

 

The obligations of the Company under this
Section 15 will survive the payment or transfer of any Note, the enforcement,
amendment or waiver of any provision of this Agreement or the Notes, and the
termination of this Agreement.

 

16.                               SURVIVAL OF REPRESENTATIONS AND
WARRANTIES; ENTIRE AGREEMENT.

 

All representations and warranties contained herein shall survive the
execution and delivery of this Agreement and the Notes, the purchase or
transfer by any Noteholder of any Note or portion thereof or interest therein
and the payment of any Note, and may be relied upon by any subsequent holder of
a Note, regardless of any investigation made at any time by or on behalf of any
holder of a Note.  All statements
contained in any certificate or other instrument delivered by or on behalf of
the Company pursuant to this Agreement shall be deemed representations and
warranties of the Company under this Agreement.  Subject to the preceding sentence, this Agreement and the Notes
embody the entire agreement

 

109

 

and understanding between the Noteholders and
the Company and supersede all prior agreements and understandings relating to
the subject matter hereof.

 

17.                               AMENDMENT AND WAIVER.

 

17.1.            Requirements.

 

This Agreement and the Notes may be amended,
and the observance of any term hereof or of the Notes may be waived (either
retroactively or prospectively), with (and only with) the written consent of
the Company and the Required Holders, except that (a) no amendment or waiver of
any of the provisions of Section 1 through Section 6, inclusive, or Section 21
hereof, or any defined term (as it is used therein), will be effective as to
any Noteholder unless consented to by each Noteholder in writing, and (b) no
such amendment or waiver may, without the written consent of the holder of each
Note at the time outstanding affected thereby, (i) subject to the provisions of
Section 12 relating to acceleration or rescission, change the amount or time of
any prepayment or payment of principal of, or reduce the rate or change the
time of payment or method of computation of interest or of the Make-Whole
Amount or Modified Make-Whole Amount on, the Notes, (ii) change the percentage
of the principal amount of the Notes the holders of which are required to
consent to any such amendment of waiver, or (iii) amend any of Section 8,
Section 11(a), Section 11(b), Section 12, Section 14.3, this Section 17,
Section 20 or Section 22.

 

17.2.            Solicitation of Holders of Notes.

 

(a) Solicitation.  The Company will provide each
Noteholder (irrespective of the amount of Notes then owned by it) with
sufficient information, sufficiently far in advance of a date of decision is
required, to enable such holder to make an informed and considered decision
with respect to any proposed amendment, waiver or consent in respect of any of
the provisions hereof or of the Notes. 
The Company will deliver executed or true and correct copies of each
amendment, waiver or consent effected

 

110

 

pursuant to the provisions of this Section 17
to each holder of outstanding Notes promptly following the date on which it is
executed and delivered by, or receives the consent of approval of, the requisite
holders of Notes.

 

(b) Payment.  The Company will not directly or
indirectly pay or cause to be paid any remuneration, whether by way of
supplemental or additional interest, fee or otherwise, or grant any security,
to any holder of Notes as consideration for or as an inducement to the entering
into by any holder of Notes of any waiver or amendment of any of the terms and
provisions hereof unless such remuneration is concurrently paid, or security is
concurrently granted, on the same terms, ratably to each holder of Notes then
outstanding even if such holder did not consent to such waiver or amendment.

 

17.3.                     Binding Effect, etc.

 

Any amendment or waiver consented to as
provided in this Section 17 applies equally to all holders of Notes and is
binding upon them and upon each future holder of any Note and upon the Company
without regard to whether such Note has been marked to indicate such amendment
or waiver.  No such amendment or waiver
will extend to or affect any obligation, covenant, agreement, Default or Event
of Default not expressly amended or waived or impair any right consequent
thereon.  No course of dealing between
the Company and the holder of any Note nor any delay in exercising any rights
hereunder or under any Note shall operate as a waiver of any rights of any
holder of such Note.  As used herein,
the term “this
Agreement”  and references thereto shall mean this Agreement as
it may from time to time be amended or supplemented.

 

17.4.       Notes held by the Company, etc.

 

Solely for the purpose of determining whether
the holders of the requisite percentage of the aggregate principal amount of
Notes then outstanding approved or consented to any amendment, waiver or
consent to be given under this

 

111

 

Agreement or the Notes, or have directed the
taking of any action provided herein or in the Notes to be taken upon the
direction of the holders of a specified percentage of the aggregate principal
amount of Notes then outstanding, Notes directly or indirectly owned by the
Company or any of its Subsidiaries or other Affiliates shall be deemed not to
be outstanding.

 

18.                               NOTICES.

 

All notices and communications provided for
hereunder shall be in writing and sent (a) by telecopy if the sender on the
same day sends a confirming copy of such notice by an
internationally-recognized expedited delivery service (charges prepaid), or (b)
by an internationally-recognized expedited delivery service (with charges
prepaid).  Any such notice must be sent:

at such other address as such Noteholder or nominee shall have specified to the
Company in writing;

 

(ii)      if to any other holder
of any Note, to such holder at such address as such other holder shall have

112

 

19.          REPRODUCTION OF DOCUMENTS.

 

This Agreement and all documents relating
hereto, including, without limitation, (a) consents, waivers and modifications
that may hereafter be executed, (b) documents received by any Noteholder at any
closing (except the Notes themselves), and (c) financial statements,
certificates and other information previously or hereafter furnished to any
Noteholder, may be reproduced by such Noteholder by any photographic, photostatic,
microfilm, microcard, miniature photographic or other similar process and such
Noteholder may destroy any original document so reproduced.  The Company agrees and stipulates that, to
the extent permitted by applicable law, any such reproduction shall be
admissible in evidence as the original itself in any judicial or administrative
proceeding (whether or not the original is in existence and whether or not such
reproduction was made by such Noteholder in the regular course of business) and
any enlargement, facsimile or further reproduction of such reproduction shall
likewise be admissible in evidence. 
This Section 19 shall not prohibit the Company or any other holder of
Notes from contesting any such reproduction to the same extent that it could
contest the original, or from introducing evidence to demonstrate the
inaccuracy of any such reproduction.

 

20.                               CONFIDENTIAL INFORMATION.

 

For the purposes of this Section 20, “Confidential Information”  means
information delivered to any Noteholder by or on behalf of the Company or any
Subsidiary in connection with the transactions contemplated by or otherwise
pursuant to this Agreement that is proprietary in nature and that was clearly
marked or labeled or otherwise adequately identified when received by such Noteholder
as being confidential information of the Company or such Subsidiary, provided
that such term does not include information that:

 

(a) was publicly known or otherwise known to
any Noteholder prior to the time of such disclosure;

 

(b) subsequently becomes publicly known
through no act or omission by

 

113

 

any Noteholder or any Person acting on its
behalf;

 

(c) otherwise becomes known to any Noteholder
other than through disclosure by the Company or any Subsidiary; or

 

(d) constitutes financial statements
delivered to any Noteholder under Section 7.1(A) or Section 7.1(B), as the case
may be, that are otherwise publicly available.

 

Each Noteholder will maintain the
confidentiality of such Confidential Information in accordance with procedures
adopted by it in good faith to protect confidential information of third
parties delivered to it, provided that such Noteholder may deliver or disclose
Confidential Information to:

 

(i)                                  its
directors, officers, trustees, employees, agents, attorneys (including
solicitors and barristers) and Affiliates (to the extent such disclosure
reasonably relates to the administration of the investment represented by its
Notes);

 

(ii)                              its
financial advisors and other professional advisors who agree to hold
Confidential Information substantially in accordance with the terms of this
Section 20;

 

(iii)                          any
other holder of any Note;

 

(iv)                            any
Institutional Investor to which it sells or offer to sell such Note or any part
thereof or any participation therein (if such Person has agreed in writing
prior to its receipt of such Confidential Information to be bound by the
provisions of this Section 20);

 

(v)                                any
Person from which such Noteholder offers to purchase any security of the
Company (if such Person has agreed in writing prior to its receipt of such
Confidential Information to be bound by the provisions of this Section 20);

 

(vi)                            any
federal or state regulatory authority having jurisdiction

 

114

 

over such Noteholder;

 

(vii)                        the
National Association of Insurance Commissioners or any similar organization, or
any nationally recognized rating agency that requires access to information
about such Noteholder’s investment portfolio; or

 

(viii)                    any other
Person to which such delivery or disclosure may be necessary or appropriate (w)
to effect compliance with any law, rule, regulation or order applicable to such
Noteholder, (x) in response to any subpoena or other legal process, (y) in
connection with any litigation to which such Noteholder is a party or (z) if an
Event of Default has occurred and is continuing, to the extent such Noteholder
may reasonably determine such delivery and disclosure to be necessary or
appropriate in the enforcement or for the protection of the rights and remedies
under its Notes, this Agreement and the Guarantees.

 

Each holder of a Note, by its acceptance of a
Note, will be deemed to have agreed to be bound by and to be entitled to the
benefits of this Section 20 as though it were a party to this Agreement.  On reasonable request by the Company in
connection with the delivery to any holder of a Note of information required to
be delivered to such holder under this Agreement or requested by such holder
(other than a holder that is a party to this Agreement or its nominee), such
holder will enter into an agreement with the Company embodying the provisions
of this Section 20.

 

21.                               INTENTIONALLY OMITTED.

 

115

 

22.                               TAX INDEMNIFICATION.

 

22.1.    Payments Free and Clear; Gross-Up of
Payments Subject to Taxes.

 

All payments whatsoever under this Agreement
and the Notes will be made free and clear of, and without liability or
withholding or deduction for or on  account of, any present or future Tax imposed or
levied by or on behalf of (a) the  United
Kingdom (or any political subdivision or taxing authority thereof or
therein) or (b) any other jurisdiction (or
any political subdivision or taxing  authority
thereof or therein) other than the United States of America (or any  political subdivision or taxing authority thereof or
therein) (x) from or through  which
any amount is paid by the Company pursuant to the terms of this  Agreement or the Notes or (y) which is a jurisdiction
of residence of the Company  for
tax purposes (any such jurisdiction described in clause (a) or (b) above being
hereinafter referred to as a “Taxing Jurisdiction”), unless the withholding or  deduction of such Tax is compelled by law.

 

If any deduction or withholding for any Tax
of a Taxing Jurisdiction shall at any time be required in respect of any
amounts to be paid by the Company  under this Agreement or the Notes, the Company will
pay on demand such  additional
amounts (including any required deduction, withholding or other  payment of Tax on or with respect to such additional
amount) as may be necessary  in
order that the net amounts received by each holder pursuant to the terms of
this  Agreement or the Notes,
after such deduction or withholding, shall equal the  amounts that would have been received had no such
deduction or withholding  been
required; provided that no payment of any additional amounts shall be
required to be made for or on account of:

 

(a)  any Tax which would not have
been imposed but for the existence of  any
present or former connection between such holder (or between a  fiduciary, settlor, beneficiary, member of,
shareholder of, or possessor of a  power
over, such holder, if such holder is an estate, trust, partnership or
corporation, or any Person other than the
holder to whom the relevant Note  or
any amount payable thereon is attributable for the purposes of such Tax)
and the United Kingdom, other than the mere
holding of the relevant Note  or
the enforcement by such holder of, or the taking of any action by such
holder to enforce, any of the rights and
remedies of such holder thereunder  or
under this Agreement, including without limitation such holder (or such
other Person described in the above
parenthetical) being or having been a  

 

116

 

citizen or resident thereof, or being or
having been engaged in a trade or business therein or having (or, for the
avoidance of doubt, holding the Note through) an establishment therein; 

 

(b) any estate, inheritance, gift, sale,
transfer, personal property or similar tax, assessment or other governmental
charge;

 

(c) any Tax that is imposed or withheld by
reason of the failure by such holder (regardless of when such holder acquired
the relevant Note) in the filing of forms, certificates, documents or returns
or other reasonably required evidence (collectively “Forms”),
required to be filed by such holder to avoid or reduce such Tax in due time to
enable the Company to make the payment in question free of, or at a reduced
rate of, Tax, provided that no holder of a Note shall be considered to have
delayed or failed to file Forms (i) in the case of any Form other than an
Inland Revenue Form FD 13 (or its counterpart for noncorporate holders), if
such Form would involve the disclosure of confidential or proprietary tax
returns or other information reasonably deemed confidential or proprietary by
the applicable holder, (ii) if such holder has filed the appropriate Forms with
the IRS (or other appropriate authority) at least 150 days prior to the payment
in question (provided however that, notwithstanding the foregoing, the
completion of a United Kingdom Inland Revenue Form FD 13 with respect to the
Company and filing thereof with the IRS within 60 days after the Effective Date
(to the extent not already filed in connection with the Existing Note Purchase
Agreements) by any Noteholder shall be deemed to be full compliance with
respect to all such requirements specified in the clause (c) above in
connection with such Noteholders purchase of Notes at such closing), or (iii)
in the case of Forms not required under existing law and practices as of the
date hereof or Forms for any Taxing Jurisdictions other than the United
Kingdom, unless the Company has requested that such Forms be filed (and has
furnished such Forms to such holder) and such holder has had a reasonable
period of time (but, in any case, no less than 60 days) to file such Forms; 

 

117

 

(d) any Tax which is payable otherwise than
by withholding from an amount payable under this Agreement or the Notes;

 

(e) or any combination of clauses (a), (b),
(c) and (d) above;

 

provided , further that no such additional
amounts shall be payable in respect of any Note to any holder of a Note in respect
of Tax which would not have arisen but for (1) the failure of such holder (or
if such holder is an estate, trust or partnership, a fiduciary, settlor,
possessor of a power over, beneficiary or member of such holder) to be a
resident of the United States of America for purposes of a tax treaty between
the United States and the Taxing Jurisdiction but only to the extent that such
additional amounts are in excess of the hypothetical additional amounts which
the Company would have been obligated to pay hereunder if such holder were a
resident in the United States of America and were eligible in full for the
benefits of such treaty with respect to interest received from the Company
(assuming that the Company and such Persons had made and obtained all relevant
claims and authorizations required under such treaty), (2) the sale by such
holder, or the agreement by such holder to sell, a Note within three months of
the acquisition of such Note, if such holder is a tax-exempt entity or (3) such
holder not being the beneficial owner of the entire interest with respect to
which such Tax is payable. 

 

The Company will furnish to the holders of
the Notes an official receipt, if any, issued by the relevant taxation or other
authorities involved for all amounts deducted or withheld as aforesaid, such
receipt to be so furnished promptly after the issuance thereof. 

 

22.2.            Tax
Refunds.

 

Each holder of a Note, by acceptance of such
Note, agrees that, with reasonable promptness after receiving written notice
from the Company to the effect that such holder is eligible for a refund in
respect of Taxes actually paid by the Company pursuant to this Section 22, such
holder will sign and deliver to or as reasonably directed by the Company any
Form provided to such holder by the 

 

118

 

Company to enable such holder to obtain a refund in respect of such
Taxes; and if such holder thereafter receives such refund in respect of such
Taxes; such holder will promptly pay such refund to the Company (together with
interest, if any, received by such holder from the relevant taxing
authority).  If a holder applies for a
refund of such Taxes prior to a request by the Company to apply for such a
refund, upon receipt of a request by the Company to apply for a refund or to
turn over the proceeds of any such refund, the holder will pay any such refund
to the Company (together with interest, if any, received by such holder from
the relevant taxing authority) promptly upon receipt of such refund, or if later,
promptly upon receipt of the request from the Company.  The Company agrees to pay all reasonable
out-of-pocket expenses incurred by a holder in connection with obtaining such
refund.  The foregoing notwithstanding,
nothing in this Section 22 shall:

 

(a) restrict the right of any recipient to
arrange its tax affairs as it shall think fit;

 

(b) require any recipient to disclose any
information regarding its tax affairs which, in such recipient’s reasonable and
good faith judgment, constitutes confidential or proprietary information; or

 

(c) require any recipient to account for any
indirect taxation benefits arising from the deduction or withholding of any
Tax.

 

22.3.            Additional Tax Indemnity for
Outstanding Company Notes.

 

Pursuant to Section 2.1(b) of the Existing
Note Purchase Agreements and subject to the terms of the Existing Note Purchase
Agreements, the Company agreed to exchange Outstanding Company Notes for
Existing Notes.  In the event that any
exchange of Outstanding Company Notes for Existing Notes pursuant to Section
2.1(b) of the Existing Note Purchase Agreements shall be deemed to constitute
an exchange which results in any tax liability to any holder of Notes under any
U.S. federal, state or local tax law providing for taxes on or measured by income
or gains (the “Holder
Tax Amount”), the Company, upon
written

 

119

 

notice thereof from such holder, shall promptly pay to such holder an
amount equal to the applicable Holder Tax Amount (together with interest and
penalties, if any) and any additional U.S. federal, state or local taxes on or
measured by income or gains which are imposed on such holder’s receipt of the
Holder Tax Amount and other amounts payable to such holder as provided in this
Section 22.3, provided that the Holder Tax Amount shall be reduced by the
present value (determined using the after-tax equivalent of the interest rate
on the Notes for which such holder’s Outstanding Company Notes were exchanged)
of U.S. federal, state or local tax benefits related to such exchange and
reasonably expected to be available to such holder, including any benefits
expected to result from amortization of bond premium that would not have been
available but for the exchange.  For
this purpose, it shall be assumed that such holder’s adjusted tax basis in the
Outstanding Company Notes at the time of the exchange is at least equal to the
principal amount of such Outstanding Company Notes at such time.  At the request of the Company, a holder of
Notes shall contest any assertion of any Holder Tax Amount with respect to such
Holder at the Company’s expense.  To the
extent reasonably permitted under U.S. federal, state or local tax law, such
holder agrees in filing its tax returns to treat the exchange in such a manner
that will not give rise to any Holder Tax Amount (but only if there is, in such
holder’s sole opinion, substantial authority for such treatment).  All calculations required pursuant to this
Section 22.3 and any determinations and assumptions necessary to perform such
calculations shall be made in such holder’s reasonable good faith
judgment.  Nothing in this Section
22.3(a) shall require such holder to disclose any information regarding its tax
affairs (including, without limitation, its tax records and returns) other than
information necessary to determine the applicability of this Section 22.3 or to
make any determination or calculation hereunder, or shall be construed in any
way as to afford the Company access to such holder’s tax records or returns
under any circumstances, or (b) shall restrict the right of such holder to
arrange its tax affairs as it shall think fit.

 

22.4.            Survival of Obligations.

 

The obligations of the Company and the
holders under this Section 22 will

 

120

 

survive the payment or transfer of any Note and the termination of this
Agreement.

 

23.                               MISCELLANEOUS.

 

23.1.    Successors and Assigns.

 

All covenants and other agreements contained in this Agreement by or on
behalf of any of the parties hereto bind and inure to the benefit of their
respective successors and assigns (including, without limitation, any
subsequent holder of a Note) whether so expressed or not.

 

23.2.    Payments Due on Non-Business Days.

 

Anything in this Agreement or the Notes to
the contrary notwithstanding, any payment of principal of or Make-Whole Amount
or Modified Make-Whole Amount or interest on any Note that is due on a date
other than a Business Day shall be made on the next succeeding Business Day
without including the additional days elapsed in the computation of the
interest payable on such next succeeding Business Day.

 

23.3.    Severability.

 

Any provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall (to the full extent permitted by
law) not invalidate or render unenforceable such provision in any other
jurisdiction.

 

23.4.    Construction.

 

Each covenant contained herein shall be
construed (absent express

 

121

 

provision to the contrary) as being independent of each other covenant
contained herein, so that compliance with any one covenant shall not (absent
such an express contrary provision) be deemed to excuse compliance with any
other covenant. Where any provision herein refers to action to be taken by any
Person, or which such Person is prohibited from taking, such provision shall be
applicable whether such action is taken directly or indirectly by such Person.

 

23.5.    Counterparts.

 

This Agreement may be executed in any number
of counterparts, each of which shall be an original but all of which together
shall constitute one instrument. Each counterpart may consist of a number of
copies hereof, each signed by less than all, but together signed by all, of the
parties hereto.

 

23.6.    Jurisdiction; Service of Process.

 

THE COMPANY HEREBY IRREVOCABLY AND
UNCONDITIONALLY AGREES THAT ANY SUIT, ACTION OR PROCEEDING WITH RESPECT TO THIS
AGREEMENT OR ANY NOTE, OR ANY ACTION OR PROCEEDING TO EXECUTE OR OTHERWISE
ENFORCE ANY JUDGMENT IN RESPECT OF ANY BREACH THEREOF, BROUGHT BY ANY HOLDER OF
A NOTE AGAINST THE COMPANY OR ANY OF ITS PROPERTY, MAY BE BROUGHT BY SUCH
HOLDER OF A NOTE IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT
OF NEW YORK OR ANY NEW YORK STATE COURT SITTING IN NEW YORK CITY AS SUCH HOLDER

SUCH COURT AND AGREES THAT PROCESS SERVED EITHER PERSONALLY OR BY REGISTERED
MAIL SHALL, TO THE EXTENT PERMITTED BY LAW, CONSTITUTE ADEQUATE SERVICE OF
PROCESS IN ANY SUCH SUIT. WITHOUT LIMITING THE FOREGOING, THE COMPANY HEREBY

BEHALF, SERVICE OF PROCESS IN THE STATE OF NEW YORK WITH RESPECT THERETO,

REQUIRED HOLDERS, WITH OFFICES IN THE STATE OF NEW YORK TO REPLACE SUCH AGENT
FOR SERVICE OF PROCESS UPON DELIVERY TO THE HOLDERS OF A REASONABLY ACCEPTABLE
AGREEMENT OF SUCH NEW AGENT AGREEING SO TO ACT.  IN ADDITION, THE COMPANY HEREBY IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER
HAVE TO THE LAYING OF VENUE IN ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR ANY NOTE BROUGHT IN THE SAID COURTS, AND HEREBY
IRREVOCABLY WAIVES ANY CLAIM THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT
IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.  NOTHING HEREIN SHALL IN ANY WAY BE DEEMED TO
LIMIT THE ABILITY OF ANY HOLDER OF A NOTE TO SERVE ANY SUCH WRITS, PROCESS OR
SUMMONSES, IN ANY MANNER PERMITTED BY APPLICABLE LAW OR TO OBTAIN JURISDICTION
OVER THE COMPANY, IN SUCH OTHER JURISDICTION, AND IN SUCH MANNER, AS MAY BE
PERMITTED BY APPLICABLE LAW.

 

23.7.            Governing
Law.

 

THIS
AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, AND THE RIGHTS OF
THE PARTIES SHALL BE GOVERNED BY, THE LAW OF THE STATE OF NEW YORK EXCLUDING
CHOICE-OF-LAW PRINCIPLES OF THE LAW OF SUCH STATE THAT WOULD REQUIRE THE
APPLICATION OF THE LAWS OF A JURISDICTION OTHER THAN SUCH STATE.

 

123

 

23.8.            Accounting Principles.

 

(a) Accounting Principles.        Notwithstanding any changes in UK GAAP or
the interpretation or application thereof subsequent to December 31, 2002, all
financial covenants herein (including those in Section 10 and the Normalization
Conditions) shall be calculated in accordance with (and compliance shall be
determined solely by reference to) UK GAAP in effect as at December 31, 2002
and as applied by the Company as of such date. 
In the event that there should occur after December 31, 2002 any changes
in UK GAAP or the interpretation or application thereof which would have a
quantifiable effect on the calculation of the financial covenants or the
Normalization Conditions, the Company agrees to provide to each of holder of a
Note, in addition to the financial information described in Section 7, such
supplemental financial information with respect to the relevant accounting periods
(calculated in accordance with UK GAAP) affected by such changes as is
reasonably necessary to allow the holders of the Notes to verify compliance
with the financial covenants and the Normalization Conditions.

 

(b) Generally.      Unless
otherwise provided herein, all financial statements delivered in connection
herewith will be prepared in accordance with UK GAAP as in effect as at the
date of, or during the period covered by such financial statements.  Unless otherwise provided herein, where the
character or amount of any asset or liability or item of income or expense, or
any consolidation or other accounting computation is required to be made for
any purpose hereunder, it shall be done in accordance with UK GAAP as in effect
on the date of, or at the end of the period covered by, the financial
statements from which such asset, liability, item of income, or item of
expense, is derived, or, in the case of any such computation, as in effect on
the date as of which such computation is required to be determined provided
that if any term defined herein includes or excludes amounts, items or concepts
that would not be included in or excluded from such term if such term was
defined with reference solely to UK GAAP, such term will

 

124

 

be deemed to include or exclude such amounts,
items or concepts as set forth herein.

 

(c) Form of
Accounts.  Subject to Section
23.8(a), if, at any time, the Company proposes to change the accounting
policies upon which any of the information provided pursuant to Section
7.1(A)(a), Section 7.1(A)(b), Section 7.1(A)(d), Section 7.1(B)(a), Section
7.1(B)(b), Section 7.1(B)(c), the financial covenants set out in Section 10 or
the Normalization Conditions is prepared, then:

 

(i)                                  it
shall notify each of the Noteholders of the proposed change;

 

(ii)                              within
five Business Days of receipt of the notification, it and the Noteholders shall
enter into good faith discussions for a period of not more than 60 days with a
view to agreeing the amendments which would be required to be made to this
Agreement (including, without limitation, the financial covenants set forth in
Section 10 and the Normalization Conditions) to reflect the basis upon which
this Agreement was entered into by it and the Noteholders; and

 

(iii)                          if no
agreement is reached under sub-clause (ii) above, then no such amendments shall
be made.

 

Any such amendments shall be made in accordance with Section 17.

 

(d)
Currency.       With respect to
any determination, consolidation or accounting computation required hereby, any
amounts not denominated in the currency in which this Agreement specifies shall
be converted to such currency in accordance with the requirements of UK GAAP
(as such requirements relate to such determination, consolidation or computation)
and, if no such requirements shall exist, converted to such currency in
accordance with normal banking procedures, at the closing rate as reported in
the most recent Financial Times (London edition) as of the date of such
determination, consolidation or computation or, if no such quotation shall then
be available, as quoted on such date by any bank reasonably

 

125

 

acceptable to the Required Holders and the
Company.

 

126

 

If you are in agreement with the foregoing,

Agreement and return it to the Company, whereupon the foregoing shall become a

B.                                    By agreeing to enter into this Agreement, the
Guarantor acknowledges that:

 

(a)                                  it will directly or indirectly gain
substantial financial and other benefits;

equivalent value and fair consideration for the purpose of any applicable

(c)                                  each holder has acted in good faith in

NOW THEREFORE, in consideration of the foregoing and other good and valuable
consideration, the receipt of which is hereby acknowledged, the Guarantor does

from time to time, of the Notes as follows:

 

AGREEMENT:

 

1.                                      GUARANTEE.

 

1.1.                            Guaranteed Obligations.

 

The
Guarantor, in consideration of the execution and delivery of the Amended and
Restated Note Purchase Agreement, hereby unconditionally, absolutely, jointly
and severally guarantees, on a continuing basis, to each holder as and for the
Guarantor’s own debt, until final and indefeasible payment has been made the
due and punctual payment by the Company of the principal of, and interest
(including interest after the commencement of any bankruptcy proceeding by or
against the Company), Make-Whole Amount and Modified Make-Whole Amount (if any)
on, the Notes at any time outstanding and the due and punctual payment of all
other amounts payable (including, without limitation, Additional Payments) by
the Company to the holders under the Amended and Restated Note Purchase
Agreement and the Notes, in each case when and as the same shall become due and
payable, whether at maturity, pursuant to mandatory or optional prepayment, by
acceleration or otherwise, all in accordance with the terms and provisions
hereof and thereof; it being the intent of the Guarantor that the guarantee set
forth herein shall be a continuing guarantee of payment and not merely a
guarantee of collection.  All of the
obligations set forth in this Section 1.1 are referred to herein as the “Guaranteed Obligations” and the Guarantee
thereof set forth in this Section 1 is referred to herein as the “Unconditional Guarantee”.

1.2.                            Payments.

 

In the event that the Company fails to make, on or before the due date
thereof, any payment to be made of any principal amount of, or interest,
Make-Whole Amount or Modified Make-Whole Amount on, or in respect of, the Notes
or of any other amounts due to any holder under the Notes or the Amended and
Restated Note Purchase Agreement (including, without limitation, Additional
Payments), after in each case giving effect to any applicable grace periods or
cure provisions or waivers or amendments, the Guarantor shall cause forthwith
to be paid the moneys, or to be performed, kept, observed, or fulfilled each of
such obligations, in respect of which such failure has occurred in accordance
with the terms and provisions of the Amended and Restated Note Purchase
Agreement and the Notes.  In furtherance
of the foregoing, if an Event of Default shall exist, all of the Guaranteed
Obligations shall, in the manner and subject to the limitations provided in the
Amended and Restated Note Purchase Agreement for the acceleration of the Notes
(including, without limitation, the provisions related to the annulment
thereof), forthwith become due and payable without notice, regardless of
whether the acceleration of the Notes shall be stayed, enjoined, delayed or
otherwise prevented.

 

Nothing shall discharge or satisfy the obligations of the Guarantor
hereunder except the full and final performance and indefeasible payment of the
Guaranteed Obligations.

 

1.3.                            Joint and Several Liability.

 

The
Guarantor acknowledges and agrees that its liabilities and the liabilities of
each of the other Subsidiary Guarantors under their respective Subsidiary
Guarantees for the due and punctual payment of the Guaranteed Obligations shall
be joint and several.

 

1.4.                            Releases.

 

The Guarantor consents and agrees that, without any notice whatsoever
to or by the Guarantor and without impairing, releasing, abating, deferring,
suspending, reducing, terminating or otherwise affecting the obligations of the
Guarantor hereunder, each holder, by action or inaction, may:

 

(a)                                  compromise or settle,
renew or extend the period of duration or the time for the payment, or
discharge the performance of, or may refuse to, or otherwise not, enforce, or
may, by action or inaction, release all or any one or more parties to, any one
or more of the Notes, the Amended and Restated Note Purchase Agreement, any
other Subsidiary Guarantee, any other guarantee or agreement or instrument
related thereto or hereto;

 

(b)                                 assign, sell or transfer, or otherwise
dispose of, any one or more of the Notes;

(c)                                  grant waivers,
extensions, consents and other indulgences of any kind whatsoever to the
Company or any other Person liable in any manner in respect of all or any part
of the Guaranteed Obligations;

 

(d)                                 amend, modify or
supplement in any manner whatsoever and at any time (or from time to time) any
one or more of the Notes, the Amended and Restated Note Purchase Agreement, any
other Subsidiary Guarantee, any other guarantee or any agreement or instrument
related thereto or hereto;

 

(e)                                  release or substitute
any one or more of the endorsers or guarantors of the Guaranteed Obligations
whether parties hereto or not; and

 

(f)                                    sell, exchange,
release, accept, surrender or enforce rights in, or fail to obtain or perfect
or to maintain, or caused to be obtained, perfected or maintained, the
perfection of  any security
interest, charge or other Lien on, by action or inaction, any property at any
time pledged or granted as security in respect of the Guaranteed Obligations,
whether so pledged or granted by the Company, the Guarantor or any other
Person.

 

The Guarantor hereby ratifies and confirms any such action specified in
this Section 1.4 and agrees that the same shall be binding upon the
Guarantor.  The Guarantor hereby waives
any and all defenses, counterclaims or offsets which the Guarantor might or
could have by reason thereof.

 

1.5.                            Waivers.

 

To the fullest extent permitted by law, the Guarantor hereby waives:

might be applicable to any sale of property of the Guarantor made under any
judgment, order or decree based on this Agreement, and the Guarantor covenants
that it will not at any time insist upon or plead, or in any manner claim or
take the benefit or advantage of any such law; and

Bankruptcy Code)) arising in respect of any payment made under this Agreement
or in connection with this Agreement, against the Company or the estate of the
Company (including Liens on the property of the Company or the estate of the
Company), in each case whether or not the Company at any time shall be the
subject of any proceeding brought under any Insolvency Law, and the Guarantor
further agrees that it will not file any claims against the Company or the
estate of the Company in the course of any such proceeding or otherwise, and
further agrees that each holder may specifically enforce the provisions of this
clause (k).

 

1.6.                            Marshaling.

 

The
Guarantor consents and agrees:

 

5

 

(a)                                  that each holder, and each Person acting for
the benefit of one or more of the holders, shall be under no obligation to
marshal any assets in favor of the Guarantor or against or in payment of any or
all of the Guaranteed Obligations; and

 

(b)                                 that, to the extent that the Company, any
other Subsidiary Guarantor or any other guarantor of any of the Guaranteed
Obligations makes a payment or payments to any holder, which payment or
payments or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside or required, for any of the foregoing
reasons or for any other reason, to be repaid or paid over to a custodian,
trustee, administrator, receiver, administrative receiver, or any other
official or party under any Insolvency Law, other common or civil law, or
equitable cause, then, to the extent of such payment or repayment, the
obligation or part thereof intended to be satisfied thereby shall be revived
and continued in full force and effect as if such payment or payments had not
been made and the Guarantor shall be primarily liable for such obligation.

 

1.7.                            Immediate Liability.

 

The
Guarantor agrees that the liability of the Guarantor in respect of the
Unconditional Guarantee shall be immediate and shall not be contingent upon the
exercise or enforcement by any holder or any other Person of whatever remedies
such holder or other Person may have against the Company, any other Subsidiary
Guarantor, or any other guarantor or the enforcement of any Lien or realization
upon any security such holder or other Person may at any time possess.

 

1.8.                            Primary Obligations.

 

The
Unconditional Guarantee is a primary and original obligation of the Guarantor
and is an absolute, unconditional, continuing guarantee of indefeasible payment
and shall remain in full force and effect without respect to any action by any
holder specified in Section 1.4 or any future changes in conditions, including,
without limitation, change of law or any invalidity or irregularity with
respect to the issuance or assumption of any obligations (including, without
limitation, the Notes) of or by the Company, any other Subsidiary Guarantor, or
any other guarantor, or with respect to the execution and delivery of any
agreement (including, without limitation, the Notes and the Amended and
Restated Note Purchase Agreement) of the Company or any other Person.

 

1.9.                            Additional Security.

 

The
Unconditional Guarantee is in addition to and is not in any way prejudiced by
any other security now or subsequently held by any holder.

 

6

 

1.10.                     No Reduction or Defense.

 

The obligations of the Guarantor under this Agreement, and the rights
of any holder to enforce such obligations by any proceedings, whether by action
at law, suit in equity or otherwise, shall not be subject to any reduction,
limitation, impairment or termination (except as set forth in Section 1.22),
whether by reason of any claim of any character whatsoever or otherwise,
including, without limitation, claims of waiver, release (except as set forth in
Section 1.22), surrender, alteration or compromise, and shall not be subject to
any defense (other than any defense based upon the irrevocable payment and
performance in full of the obligations of the Company under the Amended and
Restated Note Purchase Agreement and the Notes), set-off, counterclaim,
recoupment or termination whatsoever (except as set forth in Section 1.22).

 

Without limiting the generality of the foregoing, the obligations of
the Guarantor shall not be discharged or impaired by:

 

(a)                                  any default
(including, without limitation, any Default or Event of Default), failure or
delay, willful or otherwise, in the performance of any obligations by the
Guarantor, the Company or any of their respective Subsidiaries or Affiliates;

 

(b)                                 any proceeding of, or
involving, the Company or any of its Subsidiaries under any Insolvency Law, or
any merger, consolidation, amalgamation, reorganization, dissolution,
liquidation, sale of assets or winding up or change in corporate constitution
or corporate identity or loss of corporate identity of the Company or any of
its Subsidiaries or Affiliates;

 

(c)                                  any incapacity or
lack of power, authority or legal personality of, or dissolution or change in
the members or status of, the Company or any of its Subsidiaries or any other
Person;

 

(d)                                 impossibility or
illegality of performance on the part of the Company under the Amended and
Restated Note Purchase Agreement or the Notes or on the part of any other
Subsidiary Guarantor under any other Subsidiary Guarantee;

 

(e)                                  the invalidity,
irregularity or unenforceability of the Notes, the Amended and Restated Note
Purchase Agreement, any other Subsidiary Guarantee, or any documents referred
to therein or herein;

 

(f)                                    in respect of the
Company or any of its Subsidiaries, any change of circumstances, whether or not
foreseen or foreseeable, whether or not imputable to the Company or any such
Subsidiary, or other impossibility of performance through fire, explosion,
accident, labor disturbance, floods, droughts, embargoes, wars (whether or not
declared), terrorist activities, civil commotions, acts of God or the public
enemy, delays or failure of suppliers or carriers, inability to obtain

 

7

 

materials or any other causes affecting performance, or any other force
majeure, whether or not beyond the control of the Company or such Subsidiary
and whether or not of the kind hereinbefore specified;

 

(g)                                 any attachment, claim,
demand, charge, Lien, order, process, encumbrance or any other happening or
event or reason, similar or dissimilar to the foregoing, or any withholding or
diminution at the source, by reason of any taxes, assessments, expenses,
indebtedness, obligations or liabilities of any character, foreseen or
unforeseen, and whether or not valid, incurred by or against any Person, or any
claims, demands, charges, Liens or encumbrances of any nature, foreseen or
unforeseen, incurred by any Person, or against any sums payable under the
Amended and Restated Note Purchase Agreement, the Notes, this Agreement, or any
other Subsidiary Guarantee, so that such sums would be rendered inadequate or
would be unavailable to make the payments herein provided; or

 

(h)                                 any order, judgment,
decree, ruling or regulation (whether or not valid) of any court of any nation
or of any political subdivision thereof or any Governmental Authority, or any
other action, happening, event or reason whatsoever which shall delay,
interfere with, hinder or prevent, or in any way adversely affect, the
performance by the Company or any other Subsidiary Guarantor of any of their
respective obligations under the Amended and Restated Note Purchase Agreement
or the Notes, or the other Subsidiary Guaranties, as the case may be.

 

1.11.                     No Election.

 

Each holder shall, individually or collectively, have the right to seek
recourse against the Guarantor to the fullest extent provided for herein for
its obligations under this Agreement. 
No election to proceed in one form of action or proceeding, or against
any party, or on any obligation, shall constitute a waiver of such holder’s
right to proceed in any other form of action or proceeding or against other
parties unless such holder has expressly waived such right in writing.  Specifically, but without limiting the
generality of the foregoing, no action or proceeding by or on behalf of any
holder against the Company or any other Person under any document or instrument
evidencing obligations of the Company or such other Person to or for the
benefit of such holder shall serve to diminish the liability of the Guarantor
under this Agreement except to the extent that such holder unconditionally
shall have realized payment by such action or proceeding.

 

1.12.                     Severability.

 

Each of the rights and remedies granted under this Section 1 to each
holder in respect of the Notes held by such holder may be exercised by such
holder without notice to, or the consent of or any other action by, any other
holder.

 

8

 

1.13.                     Appropriations.

 

Until all amounts which may be or become payable by the Company under
or in connection with the Amended and Restated Note Purchase Agreement or the
Notes, by the Guarantor under or in connection with this Agreement, or by any
other Subsidiary Guarantor under or in connection with any other Subsidiary
Guarantee, have been irrevocably and indefeasibly paid in full, any holder (or
any trustee or agent on its behalf) may:

 

(a)                                  refrain from applying
or enforcing any other moneys, security or rights held or received by such
holder (or any trustee or agent on its behalf) in respect of those amounts, or
apply and enforce the same in such manner and order as it sees fit (whether
against those amounts or otherwise) and the Guarantor shall not be entitled to
the benefit of the same; and

 

(b)                                 hold in a suspense
account any moneys received from the Guarantor, or on account of the
Guarantor’s liability under this Agreement, without liability to pay interest
on those moneys.

 

1.14.                     Other Enforcement Rights.

 

Each holder may proceed to protect and enforce this Agreement by suit
or suits or proceedings in equity, at law or in bankruptcy or insolvency, and
whether for the specific performance of any covenant or agreement contained
herein or in execution or aid of any power herein granted; or for the recovery
of judgment for the obligations hereby guaranteed or for the enforcement of any
other proper, legal or equitable remedy available under applicable law.

 

1.15.                     Invalid Payments.

 

To the extent that any payment is made to any holder in respect of the
Guaranteed Obligations by any Person, which payment or any part thereof is
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required, for any of the foregoing reasons or for any other reason, to be
repaid or paid over to a custodian, trustee, administrator, receiver,
administrative receiver, or any other party or official under any Insolvency
Law, or any other common or civil law or equitable cause, then to the extent of
such payment or repayment, the obligation or part thereof intended to be
satisfied shall be revived and continued in full force and effect as if said
payment had not been made and the Guarantor shall be primarily liable for such
obligation.

 

1.16.                     No Waivers or Election of
Remedies, Expenses, etc.

 

No course of dealing and no delay on the part of any holder of any Note
in exercising any right, power or remedy shall operate as a waiver thereof or
otherwise prejudice such holder’s rights, powers or remedies.  No right, power or remedy conferred by this
Agreement or the Amended and Restated Note Purchase Agreement upon any

 

9

 

holder shall
be exclusive of any other right, power or remedy referred to herein or therein
or now or hereafter available at law, in equity, by statute or otherwise.  Without limiting the obligations of the
Company under Section [•] of the Amended and Restated Note
Purchase Agreement, the Guarantor will pay to the holder of each Note on demand
all amounts specified in Section [•]
of the Amended and Restated Note Purchase Agreement and such further amount as
shall be sufficient to cover all reasonable costs and expenses of such holder
incurred in any enforcement or collection under this Agreement, including,
without limitation, reasonable attorneys’, solicitors’ and barristers’ fees,
expenses and disbursements.

 

1.17.                     Restoration of Rights and
Remedies.

 

If any holder shall have instituted any proceeding to enforce any right
or remedy under this Agreement, the Amended and Restated Note Purchase
Agreement or any Note held by such holder and such proceeding shall have been
discontinued or abandoned for any reason, or shall have been determined
adversely to such holder, then and in every such case each such holder, the
Company and the Guarantor shall, except as may be limited or affected by any
determination in such proceeding, be restored severally and respectively to its
respective former position hereunder and thereunder, and thereafter the rights
and remedies of such holder shall continue as though no such proceeding had
been instituted.

 

1.18.                     Payment and Withholding.

 

All sums due and payable by the Guarantor under this Agreement shall be
made in full and without setoff or counterclaim and free and clear of and
without deduction for or on account of any future or present Tax.  If:

 

(a)                                  the Guarantor is
required by law to make any deduction or withholding from any sum payable by
the Guarantor to a holder hereunder, or

 

(b)                                 a holder is required
by law to make any payment, on account of any Tax or otherwise on or in
relation to any amount received or receivable by such holder hereunder,

 

then the sum payable by the Guarantor in respect of which such
deduction, withholding or payment is required to be made shall be increased to
the extent necessary to ensure that, after the making of such deduction,
withholding or payment (and after taking account of any deduction, withholding
or payment which is required to be made as a result of the increase), such
holder receives and retains a net sum equal to the sum which it would have
received and so retained had no such deduction, withholding or payment been
made; provided that each holder will comply with any reasonable request of the
Guarantor to comply with any form filing or similar reporting requirement to
reduce such deduction, withholding or payment within 60 days of the Guarantor
providing written notice to the holder of such filing or similar reporting
requirement, so long as any required forms and accompanying instructions issued
by the relevant taxing

 

10

 

authority are
provided to the holder along with such written notice.  The foregoing notwithstanding, nothing in
this Section 1.18 shall (i) restrict the right of any holder to arrange its tax
affairs as it shall think fit, (ii) require any holder to disclose any
information regarding its tax affairs which, in such holder’s reasonable and
good faith judgment, constitutes confidential or proprietary information, or
(iii) subject to the paragraph below, require any holder to account for any
indirect taxation benefits arising from the deduction, withholding or payment
of any Tax.  The obligations of the
Guarantor and the holders under this Section 1.18 will survive the payment or
transfer of any Note and the termination of this Agreement.

 

Each holder agrees that, with reasonable promptness after receiving
written notice from the Guarantor to the effect that such holder is eligible
for a refund in respect of Taxes actually paid by the Guarantor, such holder
will sign and deliver to or as reasonably directed by the Guarantor any Form
provided to such holder by the Guarantor to enable such holder to obtain a
refund in respect of such Taxes; and if such holder thereafter receives such
refund in respect of such Taxes, such holder will promptly pay such refund to
the Guarantor (together with interest, if any, received by such holder from the
relevant taxing authority).  If a holder
applies for a refund of such Taxes prior to a request by the Guarantor to apply
for such a refund, upon receipt of a request by the Guarantor to apply for a
refund or to turn over the proceeds of any such refund, the holder will pay any
such refund to the Guarantor (together with interest, if any, received by such
holder from the relevant taxing authority) promptly upon receipt of such
refund, or if later, promptly upon receipt of the request from the
Guarantor.  The Guarantor agrees to pay
all reasonable out-of-pocket expenses incurred by a holder in connection with
obtaining such refund.

 

1.19.                     Limitation on Guaranteed
Obligations.

 

It is the intention of the Guarantor and each holder of Notes that the
maximum amount of the obligations of the Guarantor hereunder shall be equal to,
but not in excess of, the maximum amount permitted by applicable law.  To that end, with respect to the
determination of the “maximum
amount permitted by applicable law,”
but only to the extent such obligations would otherwise be avoidable, the
obligations of the Guarantor hereunder shall be limited to the maximum amount
that the Guarantor is permitted to pay in respect of the Guaranteed Obligations
under any applicable Insolvency Law (including, without limitation, if
applicable, the US Bankruptcy Code).  Any
such limitation shall be apportioned amongst the Guaranteed Obligations owed to
the holders pro rata.  This Section 1.19
is intended solely to preserve the rights of each holder hereunder to the
maximum extent permitted by applicable law, and neither the Guarantor nor any
other Person shall have any rights under this Section 1.19 that it would not
otherwise have under applicable law.

 

11

 

1.20.                     Further Assurances.

 

The Guarantor will cooperate with the holders and execute such further
instruments and documents as the Required Holders shall reasonably request to
carry out, to the reasonable satisfaction of the Required Holders, the
transactions contemplated by the Amended and Restated Note Purchase Agreement,
the Notes, this Agreement and the documents and instruments related thereto.

 

1.21.                     Survival.

 

So long as the Guaranteed Obligations shall not have been fully and
finally performed and indefeasibly paid, the obligations of the Guarantor under
the Unconditional Guarantee shall survive the transfer and payment of any Note
and the payment in full of all the Notes.

 

1.22.                     Termination.

 

Notwithstanding anything to the contrary herein, this Agreement may be
terminated and all obligations of the Guarantor hereunder shall be
automatically terminated upon notice from the Company and satisfaction of the
other conditions contained in Section [•] of the Amended and Restated Note
Purchase Agreement.

 

2.                                      REPRESENTATIONS AND
WARRANTIES OF THE GUARANTOR.

 

2.1.                            Representations and
Warranties in Amended and Restated Note Purchase Agreement.

 

Without in any way limiting the generality of the warranties and
representations contained in Section 5 of the Amended and Restated Note
Purchase Agreement, each of such warranties and representations is, insofar as
it refers to a Subsidiary or a Guarantor specifically or to any Subsidiary
generally, true and correct, as of the date hereof, with respect to the
Guarantor.

 

2.2.                            Warranties and
Representations with Respect to the Guarantor and this Agreement.

 

(a)                                  Organization; Power and Authority.  The Guarantor is a corporation
duly organized and validly existing under the laws of its jurisdiction of
incorporation, and (to the extent such concept is recognized in such
jurisdiction) in good standing under the laws of its jurisdiction of
incorporation, and is duly qualified as a foreign corporation and (to the
extent such concept is recognized in such jurisdictions) is in good standing in
each jurisdiction in which such qualification is required by law, other than
those jurisdictions as to which the failure to be so qualified or in good
standing could not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect.  The
Guarantor has the corporate power and authority to own or hold under lease the

 

12

 

properties it purports to own or hold under lease, to transact the
business it transacts and proposes to transact, to execute and deliver this
Agreement, and to perform the provisions hereof.

 

(b)                                 Authorization, etc. 
This Agreement has been duly authorized by all necessary
corporate action on the part of the Guarantor, and this Agreement constitutes a
legal, valid and binding obligation of the Guarantor enforceable against the
Guarantor in accordance with its terms, except as such enforceability may be
limited by (a) applicable bankruptcy, insolvency, reorganization, moratorium,
or other similar laws affecting the enforcement of creditors’ rights generally
and (b) general principles of equity (regardless of whether such enforceability
is considered in a proceeding in equity or law).

 

(c)                                  Compliance with Laws, Other Instruments, etc.  The execution, delivery and
performance by the Guarantor of this Agreement will not

 

(i)                                     contravene, result
in any breach of, or constitute a default under, or result in the creation of
any Lien in respect of any property of the Guarantor under, any indenture,
mortgage, deed of trust, loan, purchase or credit agreement, lease, memorandum
or articles of association, corporate charter or by-laws, or any other
agreement, instrument or license to which the Guarantor is bound or subject or
by which the Guarantor or any of its properties may be bound or affected,

 

(ii)                                  conflict with or
result in a breach of any of the terms, conditions or provisions of any order,
judgment, decree, or ruling of any court, arbitrator or Governmental Authority
applicable to the Guarantor, or

 

(iii)                               violate any provision of
any applicable law or other rule or regulation of any Governmental Authority applicable
to the Guarantor.

 

(d)                                 Governmental Authorizations, etc.  No consent, approval or
authorization of, or registration, filing or declaration with, any Governmental
Authority is required in connection with the execution, delivery or performance
by the Guarantor of this Agreement.

 

(e)                                  Pari
Passu Ranking.  The Guarantor’s
obligations under this Agreement will rank at least pari passu, without
preference or priority, with all of its other outstanding obligations in
respect of its senior, unsecured and unsubordinated Financial Indebtedness,
except for those obligations that are mandatorily preferred by law and not by
reason of contract.

 

(f)                                    Solvency of Guarantor.  The fair value of the business and assets of the
Guarantor will be in excess of the amount that will be required to pay the
total liabilities of the Guarantor, in each case after giving effect to this
Agreement.  The Guarantor, after giving
effect to this Agreement, will:

 

13

 

(i)                                     not be “insolvent” (as such term is defined in the
US Bankruptcy Code),

 

(ii)                                  not be unable to pay
its debts (within the meaning of Section 123(1)(a) or (c) or Section 123(2) of
the Insolvency Act), or

 

(iii)                               not be engaged in any
business or transaction, or about to engage in any business or transaction, for
which the Guarantor has an unreasonably small capital, and the Guarantor has no
intent to:

 

(A)                              hinder, delay or defraud
any entity to which it is, or will become, on or after the date hereof,
indebted, or

 

(B)                                incur debts that would
be beyond its ability to pay as they mature; or

 

(iv)                              not
have made a transfer or incurred any obligation under a Financing Document with
the intent to hinder, delay or defraud any of its present or future creditors.

 

3.                                      COVENANTS.

 

3.1.                            Covenants in Amended and
Restated Note Purchase Agreement.

 

The Guarantor will comply with each of the provisions of Section [•] and Section [•] of the Amended and
Restated Note Purchase Agreement, and each other covenant and agreement
contained therein, that is applicable to a Subsidiary or a Guarantor
specifically or to any Subsidiary generally.

 

3.2.                            Pari Passu Ranking.

 

The Guarantor shall procure that its obligations under this Agreement
will at all times rank at least pari passu, without preference or priority,
with all of its other outstanding obligations in respect of its senior,
unsecured and unsubordinated Financial Indebtedness, except for those
obligations that are mandatorily preferred by law and not by reason of
contract.

 

4.                                      PAYMENTS ON NOTES.

 

4.1.                            Place and Manner of Payment.

 

The Guarantor will make all payments in respect hereof to the holders
at the place and in the manner specified in Section [•] of the Amended and
Restated Note Purchase Agreement.

 

14

 

4.2.                            Currency
of Payment.

 

All payments under this Agreement shall be made in US Dollars.  To the fullest extent permitted by
applicable law, the obligation of the Guarantor in respect of any amount due
under or in respect of this Agreement, notwithstanding any payment in any
currency other than US Dollars, whether as a result of (i) any judgment or
order or the enforcement thereof, (ii) the realization on any security, (iii)
the liquidation of the Guarantor, (iv) any voluntary payment by the Guarantor
or (v) any other reason, shall be discharged only to the extent of the amount
in US Dollars that each holder entitled to receive such payment may, in
accordance with normal banking procedures, purchase in the foreign exchange
markets in London, England with the sum paid in such other currency (after any
premium and costs of exchange) on the Business Day immediately following the
day on which such holder receives such payment and if the amount in US Dollars
that may be so purchased for any reason is less than the amount originally due,
the Guarantor shall indemnify and save harmless such holder from and against
all loss or damage arising out of or as a result of such deficiency.  This indemnity shall constitute an
obligation separate and independent from the other obligations contained in
this Agreement, shall give rise to a separate and independent cause of action,
shall apply irrespective of any indulgence granted by such holder from time to
time and shall continue in full force and effect notwithstanding any judgment
or order for a liquidated sum in respect of an amount due under this Agreement,
the Amended and Restated Note Purchase Agreement or under any judgment or
order.

 

5.                                      SURVIVAL
OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT.

 

All representations and warranties contained herein shall survive the
execution and delivery of this Agreement, the purchase or transfer by any
Noteholder of any Note or portion thereof or interest therein and the payment
of any Note, and may be relied upon by any subsequent holder of a Note,
regardless of any investigation made at any time by or on behalf of any
Noteholder or any other holder of a Note. 
All statements contained in any certificate or other instrument
delivered by or on behalf of the Guarantor pursuant to this Agreement or the
Amended and Restated Note Purchase Agreement shall be deemed representations
and warranties of the Guarantor under this Agreement.  Subject to the preceding sentence, this Agreement embodies the
entire agreement and understanding between the Noteholders and the Guarantor
and supersedes all prior agreements and understandings relating to the subject
matter hereof.

 

6.                                      AMENDMENT
AND WAIVER.

 

6.1.                            Requirements.

 

This Agreement may be amended, and the observance of any term hereof
may be waived (either retroactively or prospectively), with (and only with) the
written consent of the Guarantor and the Required Holders, except that (a) no
amendment or waiver of any

 

15

 

of the
provisions of Section 2, hereof, or any defined term (as it is used therein),
will be  effective as to any
holder unless consented to by such holder in writing, and (b) no such amendment
or waiver may, without the written consent of the holder of each Note at the
time outstanding affected thereby, (i) change the percentage of the principal
amount of the Notes the holders of which are required to consent to any such
amendment or waiver, (ii) amend any of Section 1, Section 4 or this Section 6,
or (iii) release, or have the effect of releasing, the Guarantor from its
liability for any of the Guaranteed Obligations (other than as provided in
Section 1.22).

 

6.2.                            Solicitation of Holders of
Notes.

 

(a)                                  Solicitation.  The
Guarantor will provide each holder of the Notes (irrespective of the amount of
Notes then owned by it) with sufficient information, sufficiently far in
advance of the date a decision is required, to enable such holder to make an
informed and considered decision with respect to any proposed amendment, waiver
or consent in respect of any of the provisions hereof.  The Guarantor will deliver executed or true
and correct copies of each amendment, waiver or consent effected pursuant to
the provisions of this Section 6 to each holder of outstanding Notes promptly
following the date on which it is executed and delivered by, or receives the
consent or approval of, the requisite holders of Notes.

 

(b)                                 Payment.  The Guarantor will not directly or
indirectly pay or cause to be paid any remuneration, whether by way of
supplemental or additional interest, fee or otherwise, or grant any security,
to any holder of Notes as consideration for or as an inducement to the entering
into by any holder of Notes of any waiver or amendment of any of the terms and
provisions hereof unless such remuneration is concurrently paid, or security is
concurrently granted, on the same terms, ratably to each holder of Notes then
outstanding even if such holder did not consent to such waiver or amendment.

 

6.3.                            Binding Effect, etc.

 

Any amendment or waiver consented to as provided in this Section 6
applies equally to all holders of Notes and is binding upon them and upon each
future holder of any Note and upon the Guarantor without regard to whether such
Note has been marked to indicate such amendment or waiver.  No such amendment or waiver will extend to
or affect any obligation, covenant, agreement, Default or Event of Default not
expressly amended or waived or impair any right consequent thereon.  No course of dealing between the Guarantor
and the holder of any Note nor any delay in exercising any rights hereunder or
under any Note shall operate as a waiver of any rights of any holder of such
Note.  As used herein, the term “this Agreement” and
references thereto shall mean this Agreement as it may from time to time be
amended or supplemented.

 

16

 

6.4.                            Notes held by Guarantor,
etc.

 

Solely for the purpose of determining whether the holders of the
requisite percentage of the aggregate principal amount of Notes then
outstanding approved or consented to any amendment, waiver or consent to be
given under this Agreement, or have directed the taking of any action provided
herein to be taken upon the direction of the holders of a specified percentage
of the aggregate principal amount of Notes then outstanding, Notes directly or
indirectly owned by the Guarantor, the Company or any of their respective
Affiliates shall be deemed not to be outstanding.

 

7.                                      NOTICES.

 

All notices and communications provided for hereunder shall be in
writing and sent (a) by telecopy if the sender on the same day sends a
confirming copy of such notice by an internationally-recognized expedited
delivery service (with charges prepaid), or (b) by an internationally-recognized
expedited delivery service (with charges prepaid).  Any such notice must be sent:

 

(i)                                     if to any holder,
to such holder’s address for notices determined pursuant to Section [•] of the Amended and
Restated Note Purchase Agreement, or

 

(ii)                                  if to the Guarantor,
to the Guarantor c/o Spirent plc, Gatwick Road, Crawley, West Sussex RH10 2RZ,

or at such other address as the Guarantor shall have specified to the holder of
each Note in writing (with a copy to the Company in the manner provided in the
Amended and Restated Note Purchase Agreement).

 

Notices
under this Section 7 will be deemed given only when actually received.

 

8.                                      REPRODUCTION OF DOCUMENTS.

 

This Agreement and all documents relating thereto, including, without
limitation, (a) consents, waivers and modifications that may hereafter be
executed, (b) documents received by any Noteholder at the Closing (except the
Notes themselves), and (c) financial statements, certificates and other
information previously or hereafter furnished to the holders, may be reproduced
by the holders by any photographic, photostatic, microfilm, microcard,
miniature photographic or other similar process and the holders may destroy any
original document so reproduced.  The
Guarantor agrees and stipulates that, to the extent permitted by applicable
law, any such reproduction shall be admissible in evidence as the original
itself in any judicial or administrative proceeding (whether or not the
original is in existence and whether or not such reproduction was made by any
such holder in the regular course of business) and any enlargement, facsimile
or further reproduction of such reproduction shall likewise be admissible in
evidence.  This Section 8 shall not
prohibit the Guarantor or any other holder of Notes from contesting any such

 

17

 

reproduction
to the same extent that it could contest the original, or from introducing
evidence to demonstrate the inaccuracy of any such reproduction.

exclusive benefit of the Guarantor and the holders.

[                          ]

 

BY:

 

(1)                                [                                ],
a corporation/limited company organized and existing under the laws of [                                ] (the “Guarantor”, which expression shall include its successors
and assigns),

 

IN FAVOUR OF

 

(2)                                 Each of the Noteholders (as defined below)
and each of the other holders from time to time of the Notes (as defined below)
(each a “Holder” and, together, the “Holders”).

 

WHEREAS:

 

(A)                               SPIRENT plc (formerly known as Bowthorpe plc), a limited
company organized and existing under the laws of England and Wales with
registered number 470893 (together with its successors and assigns, the “Company”), entered into
those certain separate Note Purchase Agreements each dated November 23,
1999 (as amended on November 14, 2000 and as further amended and restated on
March •, 2003 and as
may be further amended or varied from time to time in accordance with the terms
thereof, the “Amended and Restated Note
Purchase Agreement”), with each of the purchasers named on
Schedule A thereto (such purchasers, together with their respective transferees
and assignees, being referred to herein, individually, as a “Noteholder”, and,
collectively, as the “Noteholders”)
pursuant to which the Company issued and sold to the Noteholders (a)
US$10,000,000 principal amount of its 7.94% Senior A Senior Notes due November
23, 2006 (including any amendments, restatements or modifications from time to
time, the “Series A Notes”, such term
to include any such notes issued in substitution therefore pursuant to
Section • of the Amended
and Restated Note Purchase Agreement), (b) US$63,406,000 principal amount of
its 8.06% Series B Senior Notes due November 23, 2009 (including any
amendments, restatements or modifications from time to time, the “Series B Notes”, such term
to include any such notes issued in substitution therefore pursuant to
Section • of the Amended
and Restated Note Purchase Agreement), (c) US$115,000,000 principal amount of
its 8.16% Series C Senior Notes due November 23, 2009 (including any
amendments, restatements or modifications from time to time, the “Series C Notes”, such term
to include any such notes issued in substitution therefore pursuant to
Section • of the Amended
and Restated Note Purchase Agreement) and (d) US$29,594,000 principal amount of
its Fixed Rate Series D Senior Notes due November 23, 2009 (including any
amendments, restatements or modifications from time to time, the

 

 

“Series D Notes”, such
term to include any such notes issued in substitution therefore pursuant to
Section • of the Amended
and Restated Note Purchase Agreement) (the Series A Notes, the Series B Notes,
the Series C Notes and the Series D Notes are referred to herein, collectively,
as the “Notes”).

 

(B)                                To induce the Noteholders to enter into the
Amended and Restated Note Purchase Agreement, the Guarantor will
unconditionally guarantee all of the payment obligations of the Company under
and pursuant to the Amended and Restated Note Purchase Agreement and the Notes
pursuant to the terms and provisions of this Guarantee.

 

NOW THIS DEED WITNESSES as follows: 

 

1.  GUARANTEE.

 

1.1.  Guarantee.

 

(a)                                 Guarantee.  In
consideration of the execution and delivery of the Amended and Restated Note
Purchase Agreement by the Noteholders, the Guarantor hereby absolutely,
irrevocably, unconditionally, jointly and severally as principal obligor
guarantees to each of the Holders the due and punctual payment and performance
of the Guaranteed Obligations (as defined in clause (b) of this Section 1.1),
and, accordingly, if and when the Company shall default in the due and punctual
payment of any of the Guaranteed Obligations, then it shall on demand by such
Holder pay to such Holder, in the currency in which the same falls due for
payment under the terms of the Amended and Restated Note Purchase Agreement (as
specifically provided in Section • of the Amended and Restated Note Purchase
Agreement), that part of the Guaranteed Obligations due and owing to such
Holder when and as the same shall become due and payable, whether at maturity,
pursuant to any mandatory or optional prepayment, by acceleration or otherwise,
as if the Guarantor instead of the Company was expressed to be the principal
obligor all in accordance with the terms and provisions hereof and thereof
(regardless of whether, in the case of any acceleration, such acceleration
shall be stayed, enjoined, delayed or otherwise prevented under applicable law
or otherwise).

 

(b)                                 Guaranteed
Obligations.  In this Guarantee,  “Guaranteed
Obligations” means, in relation to each Holder, all
moneys and other amounts which are now, or at any time hereafter shall become,
due and owing by the Company to such Holder under or pursuant to the Amended
and Restated Note Purchase Agreement and the Notes, including, without
limitation, in respect of (i) the principal of, and interest on, and the Make-Whole

 

 

Amount
and Modified Make-Whole Amount (if any) on, the Notes, (ii) any additional
amounts which may be owing to such Holder pursuant to the terms of
Section •
of the Amended and Restated Note Purchase Agreement, and (iii) any swap
breakage costs and any other amounts payable by the Company to any Holder in
connection with any late payment of interest or principal (including amounts
owing under Section •
of the Amended and Restated Note Purchase Agreement), in each case pursuant to
the terms and provisions of the Amended and Restated Note Purchase Agreement.

 

(c)                                  Guarantee
of  Payment.  The guarantee given under this Section 1 is a
guarantee of payment and not a guarantee of collection.

 

1.2.  Continuing Guarantee.

 

This
Guarantee is a continuing security and (subject to Section • of the Amended and Restated Note Purchase
Agreement) shall remain in full force and effect until the Guaranteed
Obligations have been paid, discharged or satisfied in full notwithstanding the
liquidation or other incapacity or any change in the constitution of the
Company or of the Guarantor or in the name and style of either of them or any
settlement of account or other matter whatsoever and regardless of any
intermediate payment or discharge in whole or in part.

 

1.3.  Additional Security.

 

This
Guarantee is in addition to and shall not merge with or otherwise prejudice or
affect or be prejudiced by any other right, remedy, guarantee (including,
without limitation, any other Subsidiary Guarantee), indemnity or security and
may be enforced without first having recourse to the same or any other bill,
note, mortgage, charge, pledge or other Lien now or hereafter held by or
available to all or any of the Holders.

 

1.4.  Matters Not to Reduce the Guarantor’s
Liability.

 

(a)                                 Invalidity
or Unenforceability.  If any purported obligation or liability of
the Company which is the subject of this Guarantee is not or ceases to be valid
or enforceable on any ground whatsoever whether or not known to any of the Holders,
including but not limited to any defect in or want of powers of the Company or
irregular exercise thereof or lack of authority by any Person purporting to act
on behalf of the Company or any legal or other limitation (whether under the
Limitation Act or otherwise), disability, incapacity or any change in the
constitution of, or any amalgamation, reconstruction or liquidation of, the
Company, the Guarantor shall nevertheless be liable to indemnify the Holders in
respect of that purported obligation or liability as if the same were fully
valid and

 

 

enforceable
and the Guarantor were the principal debtor in respect thereof.  The Guarantor as principal obligor and as a
separate and independent obligation from its liabilities under Section 1.1
hereby agrees to keep the Holders fully indemnified on demand in the currency
in which such purported obligation or liability arose (as specifically provided
in Section •
of the Amended and Restated Note Purchase Agreement) against all damages,
losses, costs and expenses suffered or incurred by any of the Holders arising
from any failure of the Company to carry out or discharge any such purported
obligation or liability.

 

(b)                                 Other
Matters.  The liability of the Guarantor shall not be
affected nor shall this Guarantee be discharged or diminished by reason of:

 

(i)                                     any present or future bill, note, guarantee
(including, without limitation, any other Subsidiary Guarantee), indemnity,
mortgage, charge, pledge, or other Lien or security, or right or remedy held by
or available to all or any of the Holders, being or becoming wholly or in part
void, voidable or unenforceable on any ground whatsoever or by all or any of
the Holders from time to time dealing with, exchanging, varying, realizing,
releasing or failing to perfect or enforce any of the same; or

 

(ii)                                  all or any of the Holders compounding with,
discharging, releasing or varying the liability of or granting any time,
indulgence or concession to the Company or any other Person or renewing,
determining or varying any bill, promissory note or other negotiable
instrument, accommodation, facility or transaction in any manner whatsoever or
concurring in, accepting or varying any compromise, arrangement or settlement
or omitting to claim or enforce payment from a principal debtor or any other
Person; or

 

(iii)                               any act or omission which would not have
discharged or affected the liability of the Guarantor had it been a principal
debtor instead of guarantor or by anything done or omitted which but for this
provision might operate to exonerate the Guarantor.

 

1.5.  Guarantor Not to Take Security.

 

The
Guarantor warrants to the Holders that it has not taken or received, and
undertakes not to take or receive, the benefit of any security from the Company
in connection with this Guarantee.  If
any such security is taken or the Guarantor receives the benefit of the same in
violation of this Section 1.5, the Guarantor declares that such security and
all moneys at any time received in

 

 

respect thereof shall be
held on trust for the Holders to be applied ratably in discharge of the
liabilities of the Guarantor to the Holders hereunder.

 

1.6.  No Competition.

 

Until
the Guaranteed Obligations have been paid, discharged or satisfied in full, the
Guarantor waives all rights of subrogation and indemnity against the Company
and agrees not to share in any security held or moneys received by all or any
of the Holders on account of such liabilities or, unless so instructed by the
Required Holders, to claim or prove in competition with all or any of the
Holders in the liquidation of the Company in respect of any moneys paid by the
Guarantor to or under this Guarantee. 
If the Guarantor receives any payment or other benefit or exercises any
set-off or counterclaim or otherwise acts in breach of this Section 1.6,
anything so received and any benefit derived directly or indirectly by the
Guarantor therefrom shall be held on trust for the Holders to be applied
ratably in discharge of the liability of the Guarantor to the Holders
hereunder.

 

1.7.  Suspense Account and
Application.

 

(a)                                  Suspense
Account.  Any money received by a Holder in connection
with this Guarantee may be placed to the credit of an interest bearing suspense
account with a view to preserving the rights of such Holder to prove for the
whole of its claims against the Company or any other Subsidiary Guarantor
liable or may be applied by such Holder in or towards satisfaction of such of
the moneys, obligations or liabilities of the Company hereby guaranteed as such
Holder in such Holder’s absolute discretion may, subject to Section l.7(b),
from time to time conclusively determine. 
The amount standing to the credit of the suspense account shall attract
interest at such reasonable market rates offered by leading banks in the London
Interbank Market for deposits in the same currency and for each successive
period of one month (or such shorter period as the amount is to be retained on
such account) as shall be available to the Holder.

 

(b)                                 Application.  The Guarantor
shall have no right to require that any sums received by a Holder from the
Guarantor under, or pursuant to, the terms of this Guarantee should be applied
at any particular time or times (provided that
in the event that the aggregate amount of any such sums received by such Holder
and interest accrued in respect of moneys on deposit in any such suspense
account referred to in Section 1.7(a) (or the equivalent provision of any
Subsidiary Guarantee) shall be equal to or in excess of the entire outstanding
Guaranteed Obligations owing to such Holder, then such Holder shall apply such
amounts in satisfaction of such Guaranteed Obligations).

 

 

1.8.  Discharge to be Conditional.

 

Any
release, discharge, settlement or arrangement on the faith of any security,
disposition or payment between the Guarantor and a Holder shall be conditional
upon no security, disposition or payment to any of the Holders by the Company
or any other Person (not being the Guarantor) being void, set aside or ordered
to be refunded pursuant to any enactment or law relating to bankruptcy,
liquidation or insolvency or for any reason whatever and, if such condition
shall not be fulfilled, each Holder shall be entitled to enforce this Guarantee
subsequently as if such release, discharge or settlement had not occurred and
any such payment had not been made.

 

1.9.  Enforcement.

 

A
Holder shall not be obliged before taking steps to enforce this Guarantee: (a)
to take action or obtain judgment in any court against the Company or any other
Person; or (b) to make, enforce or seek to enforce any claim against the
Company or any other Person under any security or other document, agreement or
arrangement.

 

1.10.  Payment and Withholdings.

 

All
sums due and payable by the Guarantor under this Guarantee shall be made in
full without set-off or counterclaim and free and clear of and (subject as
provided in the next sentence) without deduction for or on account of any
future or present Tax.  If:

 

(a)                                  the Guarantor is
required by law to make any deduction or withholding from any sum payable by
the Guarantor to a Holder hereunder; or

 

(b)                                 a Holder is required by law to make any
payment, on account of any Tax or otherwise, on or in relation to any amount
received or receivable by such Holder hereunder,

 

(excluding, in the case of
each Holder, taxes imposed on its overall net income, profits or gains, and
franchise taxes imposed on such Holder, by the jurisdiction under the laws of
which such Holder is organized or any political subdivision thereof) then the
sum payable by the Guarantor in respect of which such deduction, withholding or
payment is required to be made shall be increased to the extent necessary to
ensure that, after the making of such deduction, withholding or payment (and
after taking account of any deduction, withholding or payment which is required
to be made as a result of the increase), such Holder receives and retains a net
sum equal to the sum which it would have received and so retained had no such
deduction, withholding or payment been made; provided
that each

 

 

Holder will comply with any
reasonable request of the Guarantor to comply with any form filing or similar
reporting requirement to reduce such deduction, withholding or payment within
60 days of the Guarantor providing written notice to the Holder of such filing
or similar reporting requirement, so long as any required forms and
accompanying instructions issued by the relevant taxing authority are provided
to the Holder along with such written notice. 
The foregoing notwithstanding, nothing in this Section 1.10 shall (i)
restrict the right of any Holder to arrange its tax affairs as it shall think
fit, (ii) require any Holder to disclose any information regarding its tax
affairs which, in such Holder’s reasonable and good faith judgment, constitutes
confidential or proprietary information, or (iii) subject to the paragraph
below, require any Holder to account for any indirect taxation benefits arising
from the deduction, withholding or payment of any Tax.  The obligations of the Guarantor under this
Section l.10 will survive the payment or transfer of any Note and the
termination of this Guarantee.

 

Each
Holder agrees that, with reasonable promptness after receiving written notice
from the Guarantor to the effect that such Holder is eligible for a refund in
respect of Taxes actually paid by the Guarantor, such Holder will sign and
deliver to or as reasonably directed by the Guarantor any Form provided to such
Holder by the Guarantor to enable such Holder to obtain a refund in respect of
such Taxes; and if such Holder thereafter receives such refund in respect of
such Taxes, such Holder will promptly pay such refund to the Guarantor
(together with interest, if any, received by such Holder from the relevant
taxing authority).  If a Holder applies
for a refund of such Taxes prior to a request by the Guarantor to apply for
such a refund, upon receipt of a request by the Guarantor to apply for a refund
or to turn over the proceeds of any such refund, the Holder will pay any such
refund to the Guarantor (together with interest, if any, received by such
holder from the relevant taxing authority) promptly upon receipt of such
refund, or if later, promptly upon receipt of the request from the
Guarantor.  The Guarantor agrees to pay
all reasonable out-of-pocket expenses incurred by a Holder in connection with
obtaining such refund.

 

1.11.  Joint and Several Liability.

 

The
Guarantor acknowledges and agrees that its liabilities under this Guarantee and
the liabilities of each other Subsidiary Guarantor under their respective Subsidiary
Guarantees are joint and several.

 

1.12.  Severability.

 

The
rights of the Holders under this Guarantee are several and each Holder may
separately enforce its rights under this Guarantee.

 

 

1.13.  Survival.

 

So
long as  the Guaranteed
Obligations have not been discharged in full, the obligations of the Guarantor
under this Guarantee shall survive the transfer and payment of any Note.

 

1.14.  Payments
on Guaranteed Obligations.

 

The
Guarantor will make all payments in respect of this Guarantee to the holders in
the same manner and in the same currency as the Company is required to make
payments on the Notes in accordance with Section • of the Amended and Restated Note Purchase
Agreement.

 

1.15. Termination,
etc.

 

Nothing
shall discharge or satisfy the obligations of the Guarantor hereunder except
the full and final performance and payment of the Guaranteed Obligations.

 

1.16. Enforcement by Holders.

 

For
the purposes of the Contracts (Rights of Third Parties) Act 1999 (the “Contracts Act”), this Guarantee may be
enforced by, and will confer benefits on, each of the present and future
Holders of each of the Notes; provided, that,
for amendments and waivers as provided in Section 6.1, the consent of the
Holder or Holders at the time of that amendment and/or waiver shall be
required, but not the consent of any future Holders.

 

1.17.  Indemnity.

 

The
Guarantor irrevocably and unconditionally indemnifies as primary obligor each
Holder on demand against any loss or liability suffered by it if any Guaranteed
Obligation is or becomes unenforceable, invalid or illegal.

 

2.  REPRESENTATIONS AND WARRANTIES OF THE GUARANTOR.

 

The
Guarantor represents and warrants for the benefit of each of the Holders:

 

2.1. 
Representations and Warranties in Amended
and Restated Note Purchase Agreement.

 

Without
in any way limiting the generality of the warranties and representations
contained in Section • of the Amended and Restated Note Purchase
Agreement, each of such warranties and representations is, insofar as

 

 

it is expressed
to apply to a Subsidiary or a Guarantor specifically or to any Subsidiary
generally, true and correct, as of the date hereof, with respect to the
Guarantor.

 

2.2.  Warranties  and Representations with Respect to the Guarantor
and this Guarantee.

 

(a)                                 Organization; Power and Authority.  The Guarantor is a corporation duly
organized and validly existing under the laws of its jurisdiction of
incorporation, and is duly qualified as a foreign corporation and (to the
extent such concept is recognized in such jurisdictions) is in good standing in
each jurisdiction in which such qualification is required by law, other than
those jurisdictions as to which the failure to be so qualified or in good
standing could not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect.  The
Guarantor has the corporate power and authority to own or hold under lease the
properties it purports to own or hold under lease, to transact the business it
transacts and, as described in the Information Pack, proposes to transact, to
execute and deliver this Guarantee and to perform the provisions hereof.

 

(b)                                 Authorisation, etc.  This Guarantee has been duly authorised
by all necessary corporate action on the part of the Guarantor, and this
Guarantee constitutes a legal, valid and binding obligation of the Guarantor
enforceable against the Guarantor in accordance with its terms except as
provided in the Reservations.

 

(c)                                  Compliance
with Laws, Other Instruments, etc.  The execution, delivery and performance
by the Guarantor of this Guarantee will not:

 

(i)                                     contravene, result
in any breach of, or constitute a default under, or result in the creation of
any Lien in respect of any property of the Guarantor under, any indenture,
mortgage, deed of trust, loan, purchase or credit agreement, lease, memorandum
or articles of association, corporate charter or by-laws, or any other
agreement, instrument or license to which the Guarantor is bound or subject or
by which the Guarantor or any of its properties may be bound or affected,

 

(ii)                                  conflict with or
result in a breach of any of the terms, conditions or provisions of any order,
judgment, decree, or ruling of any court, arbitrator or Governmental Authority
applicable to the Guarantor, or

 

 

(iii)                               violate any provision of any applicable law
or other rule or regulation of any Governmental Authority applicable to the
Guarantor.

 

(d)                                 Governmental
Authorisations, etc.  No consent, approval or authorisation of, or
registration, filing or declaration with, any Governmental Authority is
required in connection with the execution, delivery or performance by the
Guarantor of this Guarantee, save as may be required under sections 155 through
158, inclusive, of the Companies Act.

(e)                                  Pari Passu
Ranking.  The Guarantor’s obligations under this
Guarantee will rank at least pari
passu, without preference or
priority, with all of its other outstanding unsecured and unsubordinated
obligations, except for those obligations that are mandatorily preferred by law
and not by reason of contract.

 

(f)                                    Solvency
of Guarantor.  The Guarantor, after giving effect to the
transactions contemplated by this Guarantee, will not be unable to pay its
debts (within the meaning of Section 123(1)(a) or (e) or Section 123(2) of the
Insolvency Act).

 

3.  COVENANTS.

 

3.1. 
Covenants in Amended and Restated Note Purchase Agreement.

 

The
Guarantor will comply with each of the provisions of Section •, Section • and Section • of the Amended and Restated Note Purchase
Agreement in so far as those provisions are expressed to apply to a Subsidiary
or a Guarantor specifically or to any Subsidiary generally.

 

3.2.  Pari  Passu
Ranking.

 

The
Guarantor shall ensure that its obligations under this Guarantee will at all
times rank at least pari paasu in
all respects with the claims of all of its other unsecured creditors save those
whose claims are preferred by any bankruptcy, receivership, insolvency,
liquidation or other similar laws of general application.

 

4.                                      TRANSACTION EXPENSES.

 

The Guarantor will pay all costs and expenses (including, without
limitation, reasonable attorneys’ fees of a special United States counsel and a
special English counsel and, if reasonably required, other local counsel)
incurred

 

 

by each Holder in connection
with this Guarantee and in connection with any amendments, waivers or consents
under or in respect of this Guarantee (whether or not such amendment, waiver or
consent becomes effective), including, without limitation: (a) the costs and
expenses incurred in enforcing or defending (or determining whether or how to
enforce or defend) any rights under this Guarantee, the Amended and Restated
Note Purchase Agreement, or the Notes or in responding to any subpoena or other
legal process or informal investigative demand issued in connection with this
Guarantee, the Amended and Restated Note Purchase Agreement, or the Notes; and
(b) the costs and expenses, including, without limitation, financial advisors’
and reporting or investigating accountants’ fees, incurred in connection with
the insolvency or bankruptcy of the Guarantor or in connection with any
work-out or restructuring of the transactions contemplated by this Guarantee,
the Amended and Restated Note Purchase Agreement, or the Notes.  The Guarantor will pay, and will save each
Holder and hold each Holder harmless from, all claims in respect of any fees,
costs or expenses if any, of brokers and finders (other than those retained by
such Holder).

 

5.  SURVIVAL OF REPRESENTATIONS AND
WARRANTIES; ENTIRE AGREEMENT.

 

All
representations and warranties contained herein shall survive the execution and
delivery of this Guarantee, the purchase or transfer by any Noteholder or other
Holder of any Note or portion thereof or interest therein and the payment of
any Note, and may be relied upon by any Holder, regardless of any investigation
made at any time by or on behalf of any Noteholder or any other Holder (it
being understood that all representations and warranties of the Guarantor
contained in this Guarantee are made only as of the date hereof).  All statements contained in any certificate
or other instrument delivered by or on behalf of the Guarantor pursuant to this
Guarantee or the Amended and Restated Note Purchase Agreement shall be deemed
representations and warranties of the Guarantor under this Guarantee (and
deemed made at the time of the delivery of such certificate or other instrument
if such delivery is after the date hereof). 
Subject to the preceding sentence, this Guarantee embodies the final
expression of all of the terms hereof and is a complete and exclusive statement
of those terms.

 

6.  AMENDMENT AND WAIVER.

 

6.1.  Requirements.

 

This
Guarantee may be amended, and the observance of any term hereof may be waived
(either retroactively or prospectively), with (and only with) the written consent
of the Guarantor and the Required Holders except that no such amendment or
waiver may, without written consent of the Holder or Holders of

 

 

each of the Notes at the
time outstanding affected thereby, (a) change the percentage of the principal amount
of the Notes the Holders of which are required to consent to any such amendment
or waiver, or (b) amend any of Section 1, Section 2 or this Section 6.

 

6.2.  Solicitation of Holders of
Notes.

 

(a)                                 Solicitation.  The Guarantor will provide each Holder (irrespective of the amount of
Notes then owned by it) with sufficient information, sufficiently far in
advance of the date a decision is required, to enable such Holder to make an
informed and considered decision with respect to any proposed amendment, waiver
or consent in respect of any of the provisions hereof.  The Guarantor will deliver executed or true
and correct copies of each amendment, waiver or consent effected pursuant to
the provisions of this Section 6 to each Holder of outstanding Notes promptly
following the date on which it is executed and delivered by, or receives the
consent or approval of, the requisite Holders.

 

(b)                                 Payment.  The Guarantor will not directly or indirectly pay or cause to be paid
any remuneration, whether by way of supplemental or additional interest, fee or
otherwise, or grant any security, to any Holder as consideration for or as an
inducement to the entering into by any Holder of any waiver or amendment of any
of the terms and provisions hereof unless such remuneration is concurrently
paid, or security is concurrently granted, on the same terms, ratably to each
Holder holding Notes then outstanding even if such Holder did not consent to
such waiver or amendment.

 

6.3.  Binding Effect, etc.

 

Any
amendment or waiver consented to as provided in this Section 6 applies equally
to all Holders and the Guarantor without regard to whether any Note held by any
Holder has been marked to indicate such amendment or waiver.  No such amendment or waiver will extend to
or affect any obligation, covenant, agreement, Default or Event of Default not
expressly amended or waived or impair any right consequent thereon.  No course of dealing between the Guarantor
and any Holder nor any delay in exercising any rights hereunder or under any
Note shall operate as a waiver of any rights of such Holder.  As used herein, the term “this Guarantee” and references thereto
shall mean this Guarantee as it may from time to time be amended or
supplemented.

 

 

6.4. Notes
held by Guarantor, etc.

 

Solely
for the purpose of determining whether Holders holding the requisite percentage
of the aggregate principal amount of Notes then outstanding approved or
consented to any amendment, waiver or consent to be given under this Guarantee,
or have directed the taking of any action provided herein to be taken upon the
direction of Holders holding a specified percentage of the aggregate principal
amount of Notes then outstanding, Notes directly or indirectly owned by the
Guarantor, the Company, any other Subsidiary or any of their respective
Affiliates shall be deemed not to be outstanding.

 

7.  NOTICES.

notice by an internationally-recognized expedited delivery service (charges
prepaid), or (b) by an internationally-recognized expedited delivery service

B.                                    By agreeing to
enter into this Agreement, the Guarantor acknowledges that:

 

(a)                                  it
will directly or indirectly gain substantial financial and other benefits;

 

(b)                                 those
benefits will constitute reasonably equivalent value and fair consideration for
the purpose of any applicable Canadian bankruptcy or

 

 

provincial
fraudulent transfer or conveyance statute and any related case law; and

 

(c)                                  each holder has acted in good faith in
connection with this Guarantee and the Restructuring Transaction.

 

NOW THEREFORE, in consideration of the foregoing and other good and valuable
consideration, the receipt of which is hereby acknowledged, the Guarantor does
hereby covenant and agree, for the benefit of all present and future holders,
from time to time, of the Notes as follows:

 

AGREEMENT:

 

1.                                      GUARANTEE.

 

1.1                               Guaranteed Obligations.

 

The
Guarantor, in consideration of the execution and delivery of the Amended and
Restated Note Purchase Agreement, hereby unconditionally, absolutely
guarantees, on a continuing basis, to each holder as and for the Guarantor’s
own debt, until final and indefeasible payment has been made the due and
punctual payment by the Company of the principal of, and interest, Make-Whole
Amount and Modified Make-Whole Amount (if any) on, the Notes at any time
outstanding and the due and punctual payment of all other amounts payable
(including, without limitation, Additional Payments) by the Company to the
holders under the Amended and Restated Note Purchase Agreement and the Notes,
in each case when and as the same shall become due and payable, whether at
maturity, pursuant to mandatory or optional prepayment, by acceleration or
otherwise, all in accordance with the terms and provisions hereof and thereof;
it being the intent of the Guarantor that the guarantee set forth herein shall
be a continuing guarantee of payment and not merely a guarantee of
collection.  All of the obligations set
forth in this Section 1.1 are referred to herein as the “Guaranteed
Obligations” and the Guarantee thereof set forth in this
Section 1 is referred to herein as the “Unconditional
Guarantee”.

 

1.2                               Payments.

 

In
the event that the Company fails to make, on or before the due date thereof,
any payment to be made of any principal amount of, or interest, Make-Whole
Amount or Modified Make-Whole Amount on, or in respect of, the Notes or of any
other amounts due to any holder under the Notes or the Amended and Restated
Note Purchase Agreement (including, without limitation, Additional Payments),
after in each case giving effect to any applicable grace periods or cure
provisions or waivers or amendments, the Guarantor shall cause forthwith to be
paid the moneys, or to be performed, kept, observed, or fulfilled each of such
obligations, in respect of which such failure has occurred in accordance with
the terms and provisions of the Amended and Restated Note Purchase Agreement
and the Notes.  In furtherance of  the foregoing, if an Event of Default shall
exist, all of the Guaranteed Obligations shall, in the manner and subject to
the limitations provided in the Amended and Restated Note Purchase Agreement
for the acceleration of the Notes (including, without limitation, the
provisions related to the annulment thereof), forthwith become due and payable
without notice, regardless of whether the acceleration of the Notes shall be
stayed, enjoined, delayed or otherwise prevented.

 

2

 

Nothing shall discharge or satisfy the obligations of the Guarantor
hereunder except the full and final performance and indefeasible payment of the
Guaranteed Obligations.

 

1.3                               Joint and Several Liability.

 

The Guarantor acknowledges and agrees that its liabilities and the
liabilities of each of the other Subsidiary Guarantors under their respective
Subsidiary Guarantees for the due and punctual payment of the Guaranteed
Obligations shall be joint and several.

 

1.4                               Releases.

 

The Guarantor consents and agrees that, without any notice whatsoever
to or by the Guarantor and without impairing, releasing, abating, deferring,
suspending, reducing, terminating or otherwise affecting the obligations of the
Guarantor hereunder, each holder, by action or inaction, may:

 

(a)                                  compromise or settle,
renew or extend the period of duration or the time for the payment, or
discharge the performance of, or may refuse to, or otherwise not, enforce, or
may, by action or inaction, release all or any one or more parties to, any one
or more of the Notes, the Amended and Restated Note Purchase Agreement, any
other Subsidiary Guarantee, any other guarantee or agreement or instrument
related thereto or hereto;

 

(b)                                 assign, sell or
transfer, or otherwise dispose of, any one or more of the Notes;

 

(c)                                  grant waivers,
extensions, consents and other indulgences of any kind whatsoever to the
Company or any other Person liable in any manner in respect of all or any part
of the Guaranteed Obligations;

 

(d)                                 amend, modify or
supplement in any manner whatsoever and at any time (or from time to time) any
one or more of the Notes, the Amended and Restated Note Purchase Agreement, any
other Subsidiary Guarantee, any other guarantee or any agreement or instrument
related thereto or hereto;

 

(e)                                  release or substitute
any one or more of the endorsers or guarantors of the Guaranteed Obligations
whether parties hereto or not; and

 

(f)                                    sell, exchange,
release, accept, surrender or enforce rights in, or fail to obtain or perfect
or to maintain, or caused to be obtained, perfected or maintained, the
perfection of any security interest, charge or other Lien on, by action or
inaction, any property at any time pledged or granted as security in respect of
the Guaranteed Obligations, whether so pledged or granted by the Company, the
Guarantor or any other Person.

 

The Guarantor hereby ratifies and confirms any such action specified in
this Section 1.4 and agrees that the same shall be binding upon the
Guarantor.  The Guarantor hereby waives
any and all defenses, counterclaims or offsets which the Guarantor might or
could have by reason thereof.

 

1.5                               Waivers.

 

To the fullest extent permitted by law, the Guarantor hereby waives:

Guaranteed Obligations, subject to the Guarantor’s right to make inquiry of
each holder to ascertain the amount of the Guaranteed Obligations at any
reasonable time;

 

(c)                                  notice of the amount
of the Guaranteed Obligations, subject to the Guarantor’s right to make inquiry

reasonable time;

 

(d)                                 notice of adverse
change in the financial condition of the Company, any of the other Subsidiary
Guarantors or any other guarantor or any other fact that might increase the
Guarantor’s risk hereunder;

 

(e)                                  notice of presentment
for payment, demand, protest, and notice thereof as to the Notes or any other
instrument;

 

(f)                                    notice of any Default or Event of Default;

 

(g)                                 all other notices and
demands to which the Guarantor might otherwise be entitled (except if such
notice or demand is specifically otherwise required to be given to the
Guarantor under this Agreement);

 

(h)                                 the right by statute
or otherwise to require any or each holder to institute suit against the
Company, any other Subsidiary Guarantor or any other guarantor or to exhaust
the rights and remedies of any or each holder against the Company, the other
Subsidiary Guarantors or any other guarantor, the Guarantor being bound to the
payment of each and all Guaranteed Obligations, whether now existing or
hereafter accruing, as fully as if such Guaranteed Obligations were directly
owing to each holder by the Guarantor;

 

(i)                                     any defense
arising by reason of any disability or other defense (other than the defense
that the Guaranteed Obligations shall have been fully and finally performed and
indefeasibly paid) of the Company or by reason of the cessation from any cause
whatsoever of the liability of the Company in respect thereof;

 

(j)                                     any stay (except
in connection with a pending appeal), valuation, appraisal, redemption or
extension law now or at any time hereafter in force that, but for this waiver,
might be applicable to any sale of property of the Guarantor made under any
judgment, order or decree based on this Agreement, and the Guarantor covenants
that it will not at any time insist upon or plead, or in any manner claim or
take the benefit or advantage of any such law; and

 

(k)                                  at all times prior to
the full and final performance and indefeasible payment of the Guaranteed
Obligations, any claim of any nature arising out of any right of indemnity,
contribution, reimbursement, indemnification or any similar right or any claim
of subrogation (whether such right or claim arises under contract, common law or
statutory or civil law) arising in respect of any payment made under this
Agreement or in connection with this Agreement, against the Company or the
estate of the Company (including Liens on the property of the Company or the
estate of the Company), in each case whether or not the Company at any time
shall be the

subject
of any proceeding brought under any Insolvency Law, and the Guarantor further
agrees that it will not file any claims against the Company or the estate of
the Company in the course of any such proceeding or otherwise, and further
agrees that each holder may specifically enforce the provisions of this clause
(k).

The
Guarantor consents and agrees:

 

(a)                                  that each holder, and each Person acting for
the benefit of one or more of the holders, shall be under no obligation to
marshal any assets in favor of the Guarantor or against or in payment of any or
all of the Guaranteed Obligations; and

 

(b)                                 that, to the extent that the Company, any
other Subsidiary Guarantor or any other guarantor of any of the Guaranteed
Obligations makes a payment or payments to any holder, which payment or
payments or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside or required, for any of the foregoing
reasons or for any other reason, to be repaid or paid over to a custodian,
trustee, administrator, receiver, administrative receiver, or any other
official or party under any Insolvency Law, other common or civil law, or
equitable cause, then, to the extent of such payment or repayment, the
obligation or part thereof intended to be satisfied thereby shall be revived
and continued in full force and effect as if such payment or payments had not
been made and the Guarantor shall be primarily liable for such obligation.

 

1.7                               Immediate Liability.

 

The
Guarantor agrees that the liability of the Guarantor in respect of the
Unconditional Guarantee shall be immediate and shall not be contingent upon the
exercise or enforcement by any holder or any other Person of whatever remedies
such holder or other Person may have against the Company, any other Subsidiary
Guarantor, or any other guarantor or the enforcement of any Lien or realization
upon any security such holder or other Person may at any time possess.

 

1.8                               Primary Obligations.

 

The
Unconditional Guarantee is a primary and original obligation of the Guarantor
and is an absolute, unconditional, continuing guarantee of indefeasible payment
and shall remain in full force and effect without respect to any action by any
holder specified in Section 1.4 or any future changes in conditions, including,
without limitation, change of law or any invalidity or irregularity with
respect to the issuance or assumption of any obligations (including, without
limitation, the Notes) of or by the Company, any other Subsidiary Guarantor, or
any other guarantor, or with respect to the execution and delivery of any
agreement (including, without limitation, the Notes and the Amended and Restated
Note Purchase Agreement) of the Company or any other Person.

 

1.9                               Additional Security

 

The
Unconditional Guarantee is in addition to and is not in any way prejudiced by
any other security now or subsequently held by any holder.

 

5

 

1.10                        No Reduction or Defense.

 

The
obligations of the Guarantor under this Agreement, and the rights of any holder
to enforce such obligations by any proceedings, whether by action at law, suit
in equity or otherwise, shall not be subject to any reduction, limitation,
impairment or termination (except as set forth in Section 1.23), whether by
reason of any claim of any character whatsoever or otherwise, including,
without limitation, claims of waiver, release (except as set forth in Section
1.23), surrender, alteration or compromise, and shall not be subject to any
defense (other than any defense based upon the irrevocable payment and
performance in full of the obligations of the Company under the Amended and
Restated Note Purchase Agreement and the Notes), set-off, counterclaim,
recoupment or termination whatsoever (except as set forth in Section 1.23).

 

Without
limiting the generality of the foregoing, the obligations of the Guarantor
shall not be discharged or impaired by: 

 

(a)                                  any
default (including, without limitation, any Default or Event of Default),
failure or delay, willful or otherwise, in the performance of any obligations
by the Guarantor, the Company or any of their respective Subsidiaries or
Affiliates;

 

(b)                                 any
proceeding of, or involving, the Company or any of its Subsidiaries under any
Insolvency Law, or any merger, consolidation, amalgamation, reorganization,
dissolution, liquidation, sale of assets or winding up or change in corporate
constitution or corporate identity or loss of corporate identity of the Company
or any of its Subsidiaries or Affiliates;

 

(c)                                  any
incapacity or lack of power, authority or legal personality of, or dissolution
or change in the members or status of, the Company or any of its Subsidiaries
or any other Person;

 

(d)                                 impossibility
or illegality of performance on the part of the Company under the Amended and
Restated Note Purchase Agreement or the Notes or on the part of any other
Subsidiary Guarantor under any other Subsidiary Guarantee; 

 

(e)                                  the
invalidity, irregularity or unenforceability of the Notes, the Amended and
Restated Note Purchase Agreement, any other Subsidiary Guarantee, or any
documents referred to therein or herein; 

 

(f)                                    in
respect of the Company or any of its Subsidiaries, any change of circumstances,
whether or not foreseen or foreseeable, whether or not imputable to the Company
or any such Subsidiary, or other impossibility of performance through fire,
explosion, accident, labor disturbance, floods, droughts, embargoes, wars
(whether or not declared), terrorist activities, civil commotions, acts of God
or the public enemy, delays or failure of suppliers or carriers, inability to
obtain materials or any other causes affecting performance, or any other force
majeure, whether or not beyond the control of the Company or such Subsidiary
and whether or not of the kind hereinbefore specified;

 

(g)                                 any
attachment, claim, demand, charge, Lien, order, process, encumbrance or any
other happening or event or reason, similar or dissimilar to the foregoing, or
any withholding or diminution at the source, by reason of any taxes,
assessments, expenses, indebtedness, obligations or liabilities of any
character, foreseen or unforeseen, and whether or not valid, incurred by or
against any Person, or any claims, demands, charges, Liens or encumbrances of
any nature, foreseen or

 

6

 

unforeseen,
incurred by any Person, or against any sums payable under the Amended and
Restated Note Purchase Agreement, the Notes, this Agreement, or any other
Subsidiary Guarantee, so that such sums would be rendered inadequate or would
be unavailable to make the payments herein provided; or 

 

(h)                                 any
order, judgment, decree, ruling or regulation (whether or not valid) of any
court of any nation or of any political subdivision thereof or any Governmental
Authority, or any other action, happening, event or reason whatsoever which
shall delay, interfere with, hinder or prevent, or in any way adversely affect,
the performance by the Company or any other Subsidiary Guarantor of any of
their respective obligations under the Amended and Restated Note Purchase
Agreement or the Notes, or the other Subsidiary Guaranties, as the case may be.

 

1.11                        No Election.

 

Each holder
shall, individually or collectively, have the right to seek recourse against
the Guarantor to the fullest extent provided for herein for its obligations
under this Agreement. No election to proceed in one form of action or
proceeding, or against any party, or on any obligation, shall constitute a
waiver of such holder’s right to proceed in any other form of action or
proceeding or against other parties unless such holder has expressly waived
such right in writing. Specifically, but without limiting the generality of the
foregoing, no action or proceeding by or on behalf of any holder against the
Company or any other Person under any document or instrument evidencing
obligations of the Company or such other Person to or for the benefit of such
holder shall serve to diminish the liability of the Guarantor under this
Agreement except to the extent that such holder unconditionally shall have
realized payment by such action or proceeding.

 

1.12                        Severability.

 

Each of the
rights and remedies granted under this Section 1 to each holder in respect of
the Notes held by such holder may be exercised by such holder without notice
to, or the consent of or any other action by, any other holder.

 

1.13                        Appropriations.

 

Until all
amounts which may be or become payable by the Company under or in connection
with the Amended and Restated Note Purchase Agreement or the Notes, by the
Guarantor under or in connection with this Agreement, or by any other
Subsidiary Guarantor under or in connection with any other Subsidiary Guarantee,
have been irrevocably and indefeasibly paid in full, any holder (or any trustee
or agent on its behalf) may:

 

(a)                                  refrain
from applying or enforcing any other moneys, security or rights held or
received by such holder (or any trustee or agent on its behalf) in respect of
those amounts, or apply and enforce the same in such manner and order as it
sees fit (whether against those amounts or otherwise) and the Guarantor shall
not be entitled to the benefit of the same; and

 

(b)                                 hold
in a suspense account any moneys received from the Guarantor, or on account of
the Guarantor’s liability under this Agreement, without liability to pay
interest on those moneys.

 

7

 

1.14                        Other Enforcement Rights.

 

Each holder
may proceed to protect and enforce this Agreement by suit or suits or
proceedings in equity, at law or in bankruptcy or insolvency, and whether for
the specific performance of any covenant or agreement contained herein or in
execution or aid of any power herein granted; or for the recovery of judgment
for the obligations hereby guaranteed or for the enforcement of any other
proper, legal or equitable remedy available under applicable law.

 

1.15                        Invalid Payments.

 

To the extent
that any payment is made to any holder in respect of the Guaranteed Obligations
by any Person, which payment or any part thereof is subsequently invalidated,
declared to be fraudulent or preferential, set aside or required, for any of
the foregoing reasons or for any other reason, to be repaid or paid over to a
custodian, trustee, administrator, receiver, administrative receiver, or any
other party or official under any Insolvency Law, or any other common or civil
law or equitable cause, then to the extent of such payment or repayment, the obligation
or part thereof intended to be satisfied shall be revived and continued in full
force and effect as if said payment had not been made and the Guarantor shall
be primarily liable for such obligation.

 

1.16                        No Waivers or Election of
Remedies, Expenses, etc.

 

No course of
dealing and no delay on the part of any holder of any Note in exercising any
right, power or remedy shall operate as a waiver thereof or otherwise prejudice
such holder’s rights, powers or remedies. No right, power or remedy conferred
by this Agreement or the Amended and Restated Note Purchase Agreement upon any
holder shall be exclusive of any other right, power or remedy referred to
herein or therein or now or hereafter available at law, in equity, by statute
or otherwise. Without limiting the obligations of the Company under Section [•] of the Amended and
Restated Note Purchase Agreement, the Guarantor will pay to the holder of each
Note on demand all amounts specified in Section [ ] of the Amended and Restated
Note Purchase Agreement and such further amount as shall be sufficient to cover
all reasonable costs and expenses of such holder incurred in any enforcement or
collection under this Agreement, including, without limitation, reasonable
attorneys’, solicitors’ and barristers’ fees, expenses and disbursements.

 

1.17                        Restoration of Rights and
Remedies.

 

If any holder
shall have instituted any proceeding to enforce any right or remedy under this
Agreement, the Amended and Restated Note Purchase Agreement or any Note held by
such holder and such proceeding shall have been discontinued or abandoned for
any reason, or shall have been determined adversely to such holder, then and in
every such case each such holder, the Company and the Guarantor shall, except
as may be limited or affected by any determination in such proceeding, be
restored severally and respectively to its respective former position hereunder
and thereunder, and thereafter the rights and remedies of such holder shall
continue as though no such proceeding had been instituted.

 

1.18                        Payment and Withholding.

 

All sums due
and payable by the Guarantor under this Agreement shall be made in full and
without setoff or counterclaim and free and clear of and without deduction for
or on account of any future or present Tax. If:

 

(a)                                  the
Guarantor is required by law to make any deduction or withholding from any sum
payable by the Guarantor to a holder hereunder, or

 

8

 

(b)                                 a
holder is required by law to make any payment, on account of any Tax or
otherwise on or in relation to any amount received or receivable by such holder
hereunder,

 

then the sum
payable by the Guarantor in respect of which such deduction, withholding or
payment is required to be made shall be increased to the extent necessary to
ensure that, after the making of such deduction, withholding or payment (and
after taking account of any deduction, withholding or payment which is required
to be made as a result of the increase), such holder receives and retains a net
sum equal to the sum which it would have received and so retained had no such
deduction, withholding or payment been made; provided that each holder will
comply with any reasonable request of the Guarantor to comply with any form
filing or similar reporting requirement to reduce such deduction, withholding
or payment within 60 days of the Guarantor providing written notice to the
holder of such filing or similar reporting requirement, so long as any required
forms and accompanying instructions issued by the relevant taxing authority are
provided to the holder along with such written notice. The foregoing
notwithstanding, nothing in this Section 1.18 shall (i) restrict the right of
any holder to arrange its tax affairs as it shall think fit, (ii) require any
holder to disclose any information regarding its tax affairs which, in such
holder’s reasonable and good faith judgment, constitutes confidential or
proprietary information, or (iii) subject to the paragraph below, require any
holder to account for any indirect taxation benefits arising from the
deduction, withholding or payment of any Tax. The obligations of the Guarantor
and the holders under this Section 1.18 will survive the payment or transfer of
any Note and the termination of this Agreement.

 

Each holder agrees
that, with reasonable promptness after receiving written notice from the
Guarantor to the effect that such holder is eligible for a refund in respect of
Taxes actually paid by the Guarantor, such holder will sign and deliver to or
as reasonably directed by the Guarantor any Form provided to such holder by the
Guarantor to enable such holder to obtain a refund in respect of such Taxes;
and if such holder thereafter receives such refund in respect of such Taxes,
such holder will promptly pay such refund to the Guarantor (together with
interest, if any, received by such holder from the relevant taxing authority).
If a holder applies for a refund of such Taxes prior to a request by the
Guarantor to apply for such a refund, upon receipt of a request by the Guarantor
to apply for a refund or to turn over the proceeds of any such refund, the
holder will pay any such refund to the Guarantor (together with interest, if
any, received by such holder from the relevant taxing authority) promptly upon
receipt of such refund, or if later, promptly upon receipt of the request from
the Guarantor. The Guarantor agrees to pay all reasonable out-of-pocket
expenses incurred by a holder in connection with obtaining such refund.

 

1.19                        Limitation on Guaranteed
Obligations.

 

It is the
intention of the Guarantor and each holder of Notes that the maximum amount of
the obligations of the Guarantor hereunder shall be equal to, but not in excess
of, the maximum amount permitted by applicable law. To that end, with respect
to the determination of the “maximum amount permitted by applicable law,” but
only to the extent such obligations would otherwise be avoidable, the
obligations of the Guarantor hereunder shall be limited to the maximum amount
that the Guarantor is permitted to pay in respect of the Guaranteed Obligations
under any applicable Insolvency Law (including, without limitation, if
applicable, the Bankruptcy and Insolvency
Act (Canada) and the Companies’
Creditors Arrangement Act (Canada)) and under the Criminal Code (Canada). Any such
limitation shall be apportioned amongst the Guaranteed Obligations owed to the
holders pro rata. This Section 1.19 is intended solely to preserve the rights
of each holder hereunder to

 

9

 

the maximum extent permitted by applicable
law, and neither the Guarantor nor any other Person shall have any rights under
this Section 1.19 that it would not otherwise have under applicable law.

 

1.20                        Computation of Interest.

 

The Guarantor
acknowledges that the rates of interest applicable to the Guaranteed
Obligations will be computed on the basis of a year of 360 days and paid for
the actual number of days elapsed. For purposes of the Interest Act (Canada), whenever any
interest is calculated using a rate based on a year of 360 days such rate
determined pursuant to such calculation, when expressed as an annual rate is
equivalent to (i) the applicable rate based on a year of 360 days (ii)
multiplied by the actual number of days in the calendar year in which the period
for such interest is payable (or compounded) ends, and (iii) divided by 360.

 

1.21                        Further Assurances.

 

The Guarantor
will cooperate with the holders and execute such further instruments and
documents as the Required Holders shall reasonably request to carry out, to the
reasonable satisfaction of the Required Holders, the transactions contemplated
by the Amended and Restated Note Purchase Agreement, the Notes, this Agreement
and the documents and instruments related thereto.

 

1.22                        Survival.

 

So long as the
Guaranteed Obligations shall not have been fully and finally performed and
indefeasibly paid, the obligations of the Guarantor under the Unconditional
Guarantee shall survive the transfer and payment of any Note and the payment in
full of all the Notes.

 

1.23                        Termination.

 

Notwithstanding
anything to the contrary herein, this Agreement may be terminated and all
obligations of the Guarantor hereunder shall be automatically terminated upon
notice from the Company and satisfaction of the other conditions contained in
Section [•]
of the Amended and Restated Note Purchase Agreement.

WARRANTIES OF THE GUARANTOR.

 

2.1                             Representations and
Warranties in Amended and Restated Note Purchase Agreement.

Section 5 of the Amended and Restated Note Purchase Agreement, each of such
warranties and representations is, insofar as it refers to a Subsidiary or a
Guarantor specifically or to any Subsidiary generally, true and correct, as of
the date hereof, with respect to the Guarantor.

 

2.2                             Warranties and
Representations with Respect to the Guarantor and this Agreement.

 

(a)                                  Organization; Power and
Authority.  The Guarantor is a corporation duly
organized and validly existing under the laws of its jurisdiction of
incorporation, and (to the extent such concept is recognized in such
jurisdiction) in good standing under the laws of its jurisdiction of
incorporation, and is duly qualified as a foreign

 

10

 

corporation
and (to the extent such concept is recognized in such jurisdictions) is in good
standing in each jurisdiction in which such qualification is required by law,
other than those jurisdictions as to which the failure to he so qualified or in
good standing could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect. The Guarantor has the corporate
power and authority to own or hold under lease the properties it purports to
own or hold under lease, to transact the business it transacts and proposes to
transact, to execute and deliver this Agreement, and to perform the provisions
hereof.

 

(b)                                 Authorization, etc.  This
Agreement has been duly authorized by all necessary corporate action on the
part of the Guarantor, and this Agreement constitutes a legal, valid and
binding obligation of the Guarantor enforceable against the Guarantor in
accordance with its terms, except as such enforceability may be limited by (a)
applicable bankruptcy, insolvency, reorganization, moratorium, or other similar
laws affecting the enforcement of creditors’ rights generally and (b) general
principles of equity (regardless of whether such enforceability is considered
in a proceeding in equity or law). 

 

(c)                                  Compliance with Laws, Other Instruments, etc.  The execution, delivery and
performance by the Guarantor of this Agreement will not 

 

(i)                                     contravene,
result in any breach of, or constitute a default under, or result in the
creation of any Lien in respect of any property of the Guarantor under, any
indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease,
memorandum or articles of association, corporate charter or by-laws, or any
other agreement, instrument or license to which the Guarantor is bound or
subject or by which the Guarantor or any of its properties may be bound or
affected,

 

(ii)                                  conflict
with or result in a breach of any of the terms, conditions or provisions of any
order, judgment, decree, or ruling of any court, arbitrator or Governmental
Authority applicable to the Guarantor, or

 

(iii)                               violate any provision of any applicable law or other rule or regulation of any
Governmental Authority applicable to the Guarantor. 

 

(d)                                 Governmental Authorizations, etc.  No consent, approval or
authorization of, or registration, filing or declaration with, any Governmental
Authority is required in connection with the execution, delivery or performance
by the Guarantor of this Agreement.

 

(e)                                  Pari
Passu Ranking.  The Guarantor’s obligations
under this Agreement will rank at least pari passu, without preference or
priority, with all of its other outstanding obligations in respect of its
senior, unsecured and unsubordinated Financial Indebtedness, except for those
obligations that are mandatorily preferred by law and not by reason of
contract.

 

(f)                                    Solvency of Guarantor.  At the date hereof, the realizable value of the
Guarantor’s assets is greater than the aggregate of the following amounts: (x)
the liabilities of the Guarantor; (y) the stated capital of all classes of
shares of the Guarantor, and (z) the maximum liability of the Guarantor under
this Agreement. The Guarantor, after giving effect to this Agreement, will:

 

11

 

(i)                                     not
be an “insolvent person” (as such
term is defined in the Bankruptcy and
Insolvency Act (Canada)), or

 

(ii)                                  not
be engaged in any business or transaction, or about to engage in any business
or transaction, for which the Guarantor has an unreasonably small capital, and
the Guarantor has no intent to

 

(A)                              hinder,
delay or defraud any entity to which it is, or will become, on or after the
date hereof, indebted, or 

 

(B)                                incur
debts that would be beyond its ability to pay as they mature, or

 

(iii)                               not
have made a transfer or incurred any obligation under a Financing Document with
the intent to hinder, delay or defraud any of its present or future creditors.

 

3.                                 COVENANTS.

 

3.1                               Covenants in Amended and
Restated Note Purchase Agreement.

 

The Guarantor will comply
with each of the provisions of Section [•] and Section [•] of the Amended and Restated Note Purchase
Agreement, and each other covenant and agreement contained therein, that is
applicable to a Subsidiary or a Guarantor specifically or to any Subsidiary
generally.

 

3.2                               Pari Passu Ranking.

 

The Guarantor
shall procure that its obligations under this Agreement will at all times rank

outstanding obligations in respect of its senior, unsecured and unsubordinated
Financial Indebtedness, except for those obligations that are mandatorily
preferred by law and not by reason of contract.

 

4.                                PAYMENTS ON NOTES.

 

4.1                               Place and Manner of Payment.

Purchase Agreement.

 

4.2                               Currency of Payment.

 

All payments
under this Agreement shall be made in US Dollars. To the fullest extent
permitted by applicable law, the obligation of the Guarantor in respect of any
amount due under or in respect of this Agreement, notwithstanding any payment
in any currency other than US Dollars, whether as a result of (i) any judgment
or order or the enforcement thereof, (ii) the realization on any security,
(iii) the liquidation of the Guarantor, (iv) any voluntary payment by the
Guarantor or (v) any other reason, shall be discharged only to the extent of
the amount in US Dollars that each holder entitled to receive such payment may,
in accordance with normal banking procedures, purchase in the foreign exchange
markets in

 

12

 

London, England with the sum paid in such
other currency (after any premium and costs of exchange) on the Business Day
immediately following the day on which such holder receives such payment and if
the amount in US Dollars that may be so purchased for any reason is less than
the amount originally due, the Guarantor shall indemnify and save harmless such
holder from and against all loss or damage arising out of or as a result of
such deficiency. This indemnity shall constitute an obligation separate and
independent from the other obligations contained in this Agreement, shall give
rise to a separate and independent cause of action, shall apply irrespective of
any indulgence granted by such holder from time to time and shall continue in
full force and effect notwithstanding any judgment or order for a liquidated
sum in respect of an amount due under this Agreement, the Amended and Restated
Note Purchase Agreement or under any judgment or order.

 

5.                                SURVIVAL OF REPRESENTATIONS
AND WARRANTIES; ENTIRE AGREEMENT.

 

All
representations and warranties contained herein shall survive the execution and
delivery of this Agreement, the purchase or transfer by any Noteholder of any
Note or portion thereof or interest therein and the payment of any Note, and
may be relied upon by any subsequent holder of a Note, regardless of any
investigation made at any time by or on behalf of any Noteholder or any other
holder of a Note. All statements contained in any certificate or other
instrument delivered by or on behalf of the Guarantor pursuant to this
Agreement or the Amended and Restated Note Purchase Agreement shall be deemed representations
and warranties of the Guarantor under this Agreement. Subject to the preceding
sentence, this Agreement embodies the entire agreement and understanding
between the Noteholders and the Guarantor and supersedes all prior agreements
and understandings relating to the subject matter hereof.

 

6.                                 AMENDMENT AND WAIVER.

 

6.1                                    Requirements.

 

This Agreement
may be amended, and the observance of any term hereof may be waived (either
retroactively or prospectively), with (and only with) the written consent of
the Guarantor and the Required Holders, except that (a) no amendment or waiver
of any of the provisions of Section 2, hereof, or any defined term (as it is
used therein), will be effective as to any holder unless consented to by such
holder in writing, and (b) no such amendment or waiver may, without the written
consent of the holder of each Note at the time outstanding affected thereby,
(i) change the percentage of the principal amount of the Notes the holders of
which are required to consent to any such amendment or waiver, (ii) amend any
of Section 1, Section 4 or this Section 6, or (iii) release, or have the effect
of releasing, the Guarantor from its liability for any of the Guaranteed
Obligations (other than as provided in Section 1.23).

 

6.2                                    Solicitation of Holders of
Notes.

 

(a)                                  Solicitation.  The
Guarantor will provide each holder of the Notes (irrespective of the amount of
Notes then owned by it) with sufficient information, sufficiently far in
advance of the date a decision is required, to enable such holder to make an
informed and considered decision with respect to any proposed amendment, waiver
or consent in respect of any of the provisions hereof. The Guarantor will
deliver executed or true and correct copies of each amendment, waiver or consent
effected pursuant to the provisions of this Section 6 to each holder of
outstanding

 

13

 

Notes promptly
following the dale on which it is executed and delivered by, or receives the
consent or approval of, the requisite holders of Notes.

 

(b)                                 Payment. 
The Guarantor will not directly or indirectly pay or cause to be paid
any remuneration, whether by way of supplemental or additional interest, fee or
otherwise, or grant any security, to any holder of Notes as consideration for
or as an inducement to the entering into by any holder of Notes of any waiver
or amendment of any of the terms and provisions hereof unless such remuneration
is concurrently paid, or security is concurrently granted, on the same terms,
ratably to each holder of Notes then outstanding even if such holder did not
consent to such waiver or amendment.

 

6.3                               Binding Effect, etc.

 

Any amendment
or waiver consented to as provided in this Section 6 applies equally to all
holders of Notes and is binding upon them and upon each future holder of any
Note and upon the Guarantor without regard to whether such Note has been marked
to indicate such amendment or waiver. No such amendment or waiver will extend
to or affect any obligation, covenant, agreement, Default or Event of Default
not expressly amended or waived or impair any right consequent thereon. No
course of dealing between the Guarantor and the holder of any Note nor any
delay in exercising any rights hereunder or under any Note shall operate as a
waiver of any rights of any holder of such Note. As used herein, the term “this Agreement” and references thereto
shall mean this Agreement as it may from time to time be amended or
supplemented.

 

6.4                               Notes held by Guarantor,
etc.

 

Solely for the
purpose of determining whether the holders of the requisite percentage of the
aggregate principal amount of Notes then outstanding approved or consented to
any amendment, waiver or consent to be given under this Agreement, or have
directed the taking of any action provided herein to be taken upon the
direction of the holders of a specified percentage of the aggregate principal
amount of Notes then outstanding, Notes directly or indirectly owned by the
Guarantor, the Company or any of their respective Affiliates shall be deemed
not to be outstanding.

 

7.                                      NOTICES.

 

All notices
and communications provided for hereunder shall be in writing and sent (a) by
telecopy if the sender on the same day sends a confirming copy of such notice
by an internationally-recognized expedited delivery service (with charges
prepaid), or (b) by an internationally-recognized expedited delivery service
(with charges prepaid). Any such notice must be sent:

 

14

 

(i)                                     if
to any holder, to such holder’s address for notices determined pursuant to
Section [•] of the
Amended and Restated Note Purchase Agreement, or

 

(ii)                                  if

West Sussex RH10 2RZ, England, Attention: Chief Financial Accountant, facsimile
no.: +44 1293 767677, or at such other address as the Guarantor shall have
specified to the holder of each Note in writing (with a copy to the Company in
the manner provided in the Amended and Restated Note Purchase Agreement).

 

Notices under
this Section 7 will be deemed given only when actually  received.

 

8.                                      REPRODUCTION OF DOCUMENTS.

 

This Agreement and all
documents relating thereto, including, without limitation, (a) consents,
waivers and modifications that may hereafter be executed, (b) documents
received by any Noteholder at the Closing (except the Notes themselves), and
(c) financial statements, certificates and other information previously or
hereafter furnished to the holders, may be reproduced by the holders by any photographic,
photostatic, microfilm, microcard, miniature photographic or other similar
process and the holders may destroy any original document so reproduced. The
Guarantor agrees and stipulates that, to the extent permitted by applicable
law, any such reproduction shall be admissible in evidence as the original
itself in any judicial or administrative proceeding (whether or not the
original is in existence and whether or not such reproduction was made by any
such holder in the regular course of business) and any enlargement, facsimile
or further reproduction of such reproduction shall likewise be admissible in
evidence. This Section 8 shall not prohibit the Guarantor or any other holder
of Notes from contesting any such reproduction to the same extent that it could
contest the original, or from introducing evidence to demonstrate the
inaccuracy of any such reproduction.

RIGHT TO TRIAL BY JURY.

 

10.8                        Currency Indemnity.

 

If, for the
purposes of obtaining judgment in any court in any jurisdiction with respect to
this Agreement or the Amended and Restated Note Purchase Agreement, the Notes,
any other Subsidiary Guarantee, any other guarantee or agreement related
thereto or hereto, it becomes necessary to convert into the currency of such
jurisdiction (the “Judgment Currency”) any amount due under this Agreement or
the Amended and Restated Note Purchase Agreement, the Notes, any other
Subsidiary Guarantee, any other guarantee or agreement related thereto or
hereto in any currency other than the Judgment Currency (the “Currency Due”),
then conversion shall be made at the exchange rate prevailing on the Business
Day before the day of which judgment is given. 
For this purpose, “rate of exchange” means the rate at which a holder is
able, on the relevant date, to purchase the Currency Due in accordance with
normal practice.  In the event that
there is a change in the exchange rate prevailing between the Business Day
before the day on which the judgment is given and the date of receipt by the
holder of the amount due, the Guarantor will, on the date of receipt by the
holder, pay such additional amounts, if any, or be entitled to receive
reimbursement of such amount, if any, as may be necessary to ensure that the
amount received by such holder on such date is the amount in the Judgment
Currency which when converted at the rate of exchange prevailing on the date of
receipt by such holder is the amount then due under this Agreement or the
Amended and Restated Note Purchase Agreement, the Notes, any other Subsidiary
Guarantee, any other guarantee or agreement related thereto or hereto in the
Currency Due.  If the amount of the
Currency Due which the holder is able to purchase is less than the amount of
the Currency Due originally due to it, the Guarantor shall indemnify and save
such holder harmless from and against loss or damage arising as a result of
such deficiency. The indemnity contained herein shall constitute an

 

18

 

obligation separate and independent from the other obligations
contained in this Agreement and the Amended and Restated Note Purchase
Agreement, the Notes, any other Subsidiary Guarantee, any other guarantee and
agreement related thereto or hereto, shall give rise to a separate and
independent cause of action, shall apply irrespective of any indulgence granted
by the holder from time to time and shall continue in full force and effect
notwithstanding any judgment or order for a liquidated sum in respect of an
amount due under this Agreement or under the Amended and Restated Note Purchase
Agreement, the Notes, any other Subsidiary Guarantee, any other guarantee or agreement
related thereto or hereto or under any judgment or order.

 

10.9                        Language.

 

Each instrument,
certificate, statement, legal opinion, undertaking, financial statement, report
or other document referred to herein or to be delivered hereunder shall, except
as otherwise expressly permitted hereby, be in the English language, or, if not
in the English language, accompanied by an English translation certified by an
officer of the Guarantor as correct in a manner reasonably satisfactory to the
Required Holders.

BY:

 

(1)                                  [                               ],
a corporation/limited company organized and existing under the laws of 
[                               ]
(the “Guarantor”, which expression
shall include its successors and assigns).

 

IN FAVOUR OF

 

(2)                                  Each of the Noteholders (as defined below)
and each of the other holders from time to time of the Notes (as defined below)
(each a “Holder” and, together,
the “Holders”).

 

WHEREAS:

 

(A)                              SPIRENT plc (formerly known as Bowthorpe plc), a limited
company organized and existing under the laws of England and Wales with
registered number 470893 (together with its successors and assigns, the “Company”), entered into those certain
separate Note Purchase Agreements each dated November 23, 1999 (as amended on
November 14, 2000 and as further amended and restated on March •, 2003 and as may be further amended or
varied from time to time in accordance with the terms thereof, the “Amended and Restated Note Purchase Agreement”),
with each of the purchasers named on Schedule A thereto (such purchasers,
together with their respective transferees and assignees, being referred to
herein, individually, as a “Noteholder”,
and, collectively, as the “Noteholders”)
pursuant to which the Company issued and sold to the Noteholders (a)
US$10,000,000 principal amount of its 7.94% Senior A Senior Notes due November
23, 2006 (including any amendments, restatements or modifications from time to
time, the “Series A Notes”, such
term to include any such notes issued in substitution therefore pursuant to
Section • of the Amended
and Restated Note Purchase Agreement), (b) US$63,406,000 principal amount of
its 8.06% Series B Senior Notes due November 23, 2009 (including any
amendments, restatements or modifications from time to time, the “Series B Notes”, such term to include any
such notes issued in substitution therefore pursuant to Section • of the Amended and Restated Note Purchase
Agreement), (c) US$115,000,000 principal amount of its 8.16% Series C Senior
Notes due November 23, 2009 (including any amendments, restatements or
modifications from time to time, the “Series
C Notes”, such term to include any such notes issued in substitution
therefore pursuant to Section •
of the Amended and Restated Note Purchase Agreement) and (d) US$29,594,000
principal amount of its Fixed Rate Series D Senior Notes due November 23, 2009
(including any amendments, restatements or modifications from time to time, the

 

 

“Series D
Notes”, such term to
include any such notes issued in substitution therefore pursuant to Section • of the Amended and Restated Note Purchase
Agreement) (the Series A Notes, the Series B Notes, the Series C Notes and the
Series D Notes are referred to herein, collectively, as the “Notes”).

 

(B)                                To induce the Noteholders to enter into the
Amended and Restated Note Purchase Agreement, the Guarantor will
unconditionally guarantee all of the payment obligations of the Company under
and pursuant to the Amended and Restated Note Purchase Agreement and the Notes
pursuant to the terms and provisions of this Guarantee.

 

NOW THIS
DEED WITNESSES as
follows:

 

1.    GUARANTEE.

 

1.1. Guarantee.

 

(a)                                    Guarantee.  In
consideration of the execution and delivery of the Amended and Restated Note
Purchase Agreement by the Noteholders, the Guarantor hereby absolutely,
irrevocably, unconditionally, jointly and severally as principal obligor
guarantees to each of the Holders the due and punctual payment and performance
of the Guaranteed Obligations (as defined in clause (b) of this Section 1.1),
and, accordingly, if and when the Company shall default in the due and punctual
payment of any of the Guaranteed Obligations, then it shall on demand by such
Holder pay to such Holder, in the currency in which the same falls due for
payment under the terms of the Amended and Restated Note Purchase Agreement (as
specifically provided in Section • of the Amended and Restated Note Purchase Agreement), that part of the
Guaranteed Obligations due and owing to such Holder when and as the same shall
become due and payable, whether at maturity, pursuant to any mandatory or
optional prepayment, by acceleration or otherwise, as if the Guarantor instead
of the Company was expressed to be the principal obligor all in accordance with
the terms and provisions hereof and thereof (regardless of whether, in the case
of any acceleration, such acceleration shall be stayed, enjoined, delayed or
otherwise prevented under applicable law or otherwise).

 

(b)                                    Guaranteed
Obligations.  In this Guarantee, “Guaranteed Obligations” means, in relation to each Holder,
all moneys and other amounts which are now, or at any time hereafter shall
become, due and owing by the Company to such Holder under or pursuant to the
Amended and Restated Note Purchase Agreement and the Notes, including, without
limitation, in respect of (i) the principal of, and interest on, and the
Make-Whole

 

 

Amount and Modified
Make-Whole Amount (if any) on, the Notes, (ii) any additional amounts which may
be owing to such Holder pursuant to the terms of Section • of the Amended and Restated Note Purchase
Agreement, and (iii) any swap breakage costs and any other amounts payable by
the Company to any Holder in connection with any late payment of interest or
principal (including amounts owing under Section • of the Amended and Restated Note Purchase
Agreement), in each case pursuant to the terms and provisions of the Amended
and Restated Note Purchase Agreement.

 

(c)                                   Guarantee
of Payment.   The guarantee given under this Section 1 is a
guarantee of payment and not a guarantee of collection.

 

1.2.                            Continuing Guarantee.

 

This Guarantee is a
continuing security and (subject to Section • of the Amended and Restated Note
Purchase Agreement) shall remain in full force and effect until the Guaranteed
Obligations have been paid, discharged or satisfied in full notwithstanding the
liquidation or other incapacity or any change in the constitution of the Company
or of the Guarantor or in the name and style of either of them or any
settlement of account or other matter whatsoever and regardless of any
intermediate payment or discharge in whole or in part.

 

1.3.                            Additional
Security.

 

This Guarantee is in
addition to and shall not merge with or otherwise prejudice or affect or be
prejudiced by any other right, remedy, guarantee (including, without
limitation, any other Subsidiary Guarantee), indemnity or security and may be
enforced without first having recourse to the same or any other bill, note,
mortgage, charge, pledge or other Lien now or hereafter held by or available to
all or any of the Holders.

 

1.4.                              Matters Not to Reduce the Guarantor’s
Liability.

 

(a)                                 Invalidity
or Unenforceability.  If any
purported obligation or liability of the Company which is the subject of this
Guarantee is not or ceases to be valid or enforceable on any ground whatsoever
whether or not known to any of the Holders, including but not limited to any
defect in or want of powers of the Company or irregular exercise thereof or
lack of authority by any Person purporting to act on behalf of the Company or
any legal or other limitation (whether under the Limitation Act or otherwise),
disability, incapacity or any change in the constitution of, or any
amalgamation, reconstruction or liquidation of, the Company, the Guarantor
shall nevertheless be liable to indemnify the Holders in respect of that
purported obligation or liability as if the same were fully valid and

 

 

enforceable and the Guarantor
were the principal debtor in respect thereof. 
The Guarantor as principal obligor and as a separate and independent
obligation from its liabilities under Section 1.1 hereby agrees to keep the
Holders fully indemnified on demand in the currency in which such purported
obligation or liability arose (as specifically provided in Section • of the Amended and Restated Note Purchase
Agreement) against all damages, losses, costs and expenses suffered or incurred
by any of the Holders arising from any failure of the Company to carry out or
discharge any such purported obligation or liability.

 

(b)                                 Other
Matters.  The liability of the Guarantor shall not be
affected nor shall this Guarantee be discharged or diminished by reason of: 

 

(i)                                     any present or future bill, note, guarantee
(including, without limitation, any other Subsidiary Guarantee), indemnity,
mortgage, charge, pledge, or other Lien or security, or right or remedy held by
or available to all or any of the Holders, being or becoming wholly or in part void,
voidable or unenforceable on any ground whatsoever or by all or any of the
Holders from time to time dealing with, exchanging, varying, realizing,
releasing or failing to perfect or enforce any of the same; or

 

(ii)                                  all or any of the Holders compounding with,
discharging, releasing or varying the liability of or granting any time,
indulgence or concession to the Company or any other Person or renewing,
determining or varying any bill, promissory note or other negotiable
instrument, accommodation, facility or transaction in any manner whatsoever or
concurring in, accepting or varying any compromise, arrangement or settlement
or omitting to claim or enforce payment from a principal debtor or any other
Person; or

 

(iii)                               any act or omission which would not have
discharged or affected the liability of the Guarantor had it been a principal
debtor instead of guarantor or by anything done or omitted which but for this
provision might operate to exonerate the Guarantor.

 

1.5.                            Guarantor Not to Take Security.

 

The Guarantor warrants to
the Holders that it has not taken or received, and undertakes not to take or
receive, the benefit of any security from the Company in connection with this
Guarantee.  If any such security is taken
or the Guarantor receives the benefit of the same in violation of this Section
1.5, the Guarantor declares that such security and all moneys at any time
received in

 

 

respect thereof shall be held on trust for the Holders to be applied
ratably in discharge of the liabilities of the Guarantor to the Holders
hereunder.

 

1.6.                            No
Competition.

 

Until the Guaranteed
Obligations have been paid, discharged or satisfied in full, the Guarantor
waives all rights of subrogation and indemnity against the Company and agrees
not to share in any security held or moneys received by all or any of the
Holders on account of such liabilities or, unless so instructed by the Required
Holders, to claim or prove in competition with all or any of the Holders in the
liquidation of the Company in respect of any moneys paid by the Guarantor to or
under this Guarantee.  If the Guarantor
receives any payment or other benefit or exercises any set-off or counterclaim
or otherwise acts in breach of this Section 1.6, anything so received
and any benefit derived directly or indirectly by the Guarantor therefrom shall
be held on trust for the Holders to be applied ratably in discharge of the
liability of the Guarantor to the Holders hereunder.

 

1.7.                            Suspense
Account and Application.

 

(a)                                 Suspense
Account.   Any money received by a Holder in connection
with this Guarantee may be placed to the credit of an interest bearing suspense
account with a view to preserving the rights of such Holder to prove for the
whole of its claims against the Company or any other Subsidiary Guarantor liable
or may be applied by such Holder in or towards satisfaction of such of the
moneys, obligations or liabilities of the Company hereby guaranteed as such
Holder in such Holder’s absolute discretion may, subject to Section 1.7(b),
from time to time conclusively determine. 
The amount standing to the credit of the suspense account shall attract
interest at such reasonable market rates offered by leading banks in the London
Interbank Market for deposits in the same currency and for each successive
period of one month (or such shorter period as the amount is to be retained on
such account) as shall be available to the Holder.

 

(b)                                 Application.   The Guarantor
shall have no right to require that any sums received by a Holder from the
Guarantor under, or pursuant to, the terms of this Guarantee should be applied
at any particular time or times (provided that
in the event that the aggregate amount of any such sums received by such Holder
and interest accrued in respect of moneys on deposit in any such suspense account
referred to in Section 1.7(a) (or the equivalent provision of any Subsidiary
Guarantee) shall be equal to or in excess of the entire outstanding Guaranteed
Obligations owing to such Holder, then such Holder shall apply such amounts in
satisfaction of such Guaranteed Obligations).

 

 

1.8.                             Discharge
to be Conditional.

 

Any release, discharge,
settlement or arrangement on the faith of any security, disposition or payment
between the Guarantor and a Holder shall be conditional upon no security,
disposition or payment to any of the Holders by the Company or any other Person
(not being the Guarantor) being void, set aside or ordered to be refunded
pursuant to any enactment or law relating to bankruptcy, liquidation or
insolvency or for any reason whatever and, if such condition shall not be
fulfilled, each Holder shall be entitled to enforce this Guarantee subsequently
as if such release, discharge or settlement had not occurred and any such
payment had not been made.

 

1.9.                            Enforcement.

 

A Holder shall not be
obliged before taking steps to enforce this Guarantee: (a) to take action or
obtain judgment in any court against the Company or any other Person; or (b) to
make, enforce or seek to enforce any claim against the Company or any other
Person under any security or other document, agreement or arrangement.

 

1.10.                     Payment
and Withholdings.

 

All sums due and payable by
the Guarantor under this Guarantee shall be made in full without set-off or
counterclaim and free and clear of and (subject as provided in the next
sentence) without deduction for or on account of any future or present Tax. If: 

 

(a)                                  the Guarantor is required by law to make any
deduction or withholding from any sum payable by the Guarantor to a Holder
hereunder; or 

 

(b)                                 a Holder is required by law to make any
payment, on account of any Tax or otherwise, on or in relation to any amount
received or receivable by such Holder hereunder,

 

(excluding, in the case of each Holder, taxes imposed on its overall
net income, profits or gains, and franchise taxes imposed on such Holder, by
the jurisdiction under the laws of which such Holder is organized or any
political subdivision thereof) then the sum payable by the Guarantor in respect
of which such deduction, withholding or payment is required to be made shall be
increased to the extent necessary to ensure that, after the making of such
deduction, withholding or payment (and after taking account of any deduction,
withholding or payment which is required to be made as a result of the
increase), such Holder receives and retains a net sum equal to the sum which it
would have received and so retained had no such deduction, withholding or
payment been made; provided that
each

 

 

Holder will comply with any
reasonable request of the Guarantor to comply with any form filing or similar
reporting requirement to reduce such deduction, withholding or payment within
60 days of the Guarantor providing written notice to the Holder of such filing
or similar reporting requirement, so long as any required forms and accompanying
instructions issued by the relevant taxing authority are provided to the Holder
along with such written notice.  The
foregoing notwithstanding, nothing in this Section 1.10 shall (i) restrict the
right of any Holder to arrange its tax affairs as it shall think fit, (ii)
require any Holder to disclose any information regarding its tax affairs which,
in such Holder’s reasonable and good faith judgment, constitutes confidential
or proprietary information, or (iii) subject to the paragraph below, require any
Holder to account for any indirect taxation benefits arising from the
deduction, withholding or payment of any Tax. 
The obligations of the Guarantor under this Section 1.10 will survive
the payment or transfer of any Note and the termination of this Guarantee.

 

Each Holder agrees that,
with reasonable promptness after receiving written notice from the Guarantor to
the effect that such Holder is eligible for a refund in respect of Taxes
actually paid by the Guarantor, such Holder will sign and deliver to or as
reasonably directed by the Guarantor any Form provided to such Holder by the
Guarantor to enable such Holder to obtain a refund in respect of such Taxes;
and if such Holder thereafter receives such refund in respect of such Taxes,
such Holder will promptly pay such refund to the Guarantor (together with
interest, if any, received by such Holder from the relevant taxing
authority).  If a Holder applies for a
refund of such Taxes prior to a request by the Guarantor to apply for such a
refund, upon receipt of a request by the Guarantor to apply for a refund or to
turn over the proceeds of any such refund, the Holder will pay any such refund
to the Guarantor (together with interest, if any, received by such holder from
the relevant taxing authority) promptly upon receipt of such refund, or if
later, promptly upon receipt of the request from the Guarantor.  The Guarantor agrees to pay all reasonable
out-of-pocket expenses incurred by a Holder in connection with obtaining such
refund.

 

1.11.                     Joint and
Several Liability.

 

The Guarantor acknowledges
and agrees that its liabilities under this Guarantee and the liabilities of
each other Subsidiary Guarantor under their respective Subsidiary Guarantees
are joint and several.  Without limiting
the generality of the foregoing, the Guarantor waives any rights which it may
have under the existing or future laws of Guernsey in relation to any
obligation assumed by it under this Guarantee arising by virtue of the “droit
de discussion” and “droit de division”.

 

 

1.12.                   Severability.

 

The rights of the Holders
under this Guarantee are several and each Holder may separately enforce its
rights under this Guarantee.

 

1.13.                     Survival.

 

So long as the Guaranteed
Obligations have not been discharged in full, the obligations of the Guarantor
under this Guarantee shall survive the transfer and payment of any Note.

 

1.14.                     Payments
on Guaranteed Obligations.

 

The Guarantor will make all
payments in respect of this Guarantee to the holders in the same manner and in
the same currency as the Company is required to make payments on the Notes in
accordance with Section •
of the Amended and Restated Note Purchase Agreement.

 

1.I5.                       Termination, etc.

 

Nothing shall discharge or
satisfy the obligations of the Guarantor hereunder except the full and final
performance and payment of the Guaranteed Obligations.

 

1.16.                 Enforcement
by Holders.

 

For the purposes of the
Contracts (Rights of Third Parties) Act 1999 (the “Contracts Act”), this Guarantee may be enforced by, and will
confer benefits on, each of the present and future Holders of each of the
Notes; provided, that, for
amendments and waivers as provided in Section 6.1, the consent of the Holder or
Holders at the time of that amendment and/or waiver shall be required, but not
the consent of any future Holders.

 

1.17.                 Indemnity.

 

The Guarantor irrevocably
and unconditionally indemnifies as primary obligor each Holder on demand
against any loss or liability suffered by it if any Guaranteed Obligation is or
becomes unenforceable, invalid or illegal.

 

2.     REPRESENTATIONS AND WARRANTIES OF THE
GUARANTOR.

 

The Guarantor represents and
warrants for the benefit of each of the Holders:

 

 

2.1.                            Representations
and Warranties in Amended and Restated Note Purchase Agreement.

 

Without in any way limiting
the generality of the warranties and representations contained in Section • of the Amended and Restated Note Purchase
Agreement, each of such warranties and representations is, insofar as it is
expressed to apply to a Subsidiary or a Guarantor specifically or to any
Subsidiary generally, true and correct, as of the date hereof, with respect to
the Guarantor.

 

2.2.                             Warranties
and Representations with
Respect to the  Guarantor
and this Guarantee.

 

(a)                                 Organization;
Power and Authority.  The
Guarantor is a corporation duly organized and validly existing under the laws
of its jurisdiction of incorporation, and is duly qualified as a foreign
corporation and (to the extent such concept is recognized in such
jurisdictions) is in good standing in each jurisdiction in which such
qualification is required by law, other than those jurisdictions as to which
the failure to be so qualified or in good standing could not, individually or
in the aggregate, reasonably be expected to have a Material Adverse Effect.  The Guarantor has the corporate power and
authority to own or hold under lease the properties it purports to own or hold
under lease, to transact the business it transacts and, as described in the
Information Pack, proposes to transact, to execute and deliver this Guarantee
and to perform the provisions hereof.

 

(b)                                 Authorisation,
etc.  This Guarantee has been duly authorised by all necessary corporate
action on the part of the Guarantor, and this Guarantee constitutes a legal,
valid and binding obligation of the Guarantor enforceable against the Guarantor
in accordance with its terms except as provided in the Reservations.

 

(c)                                  Compliance
with Laws, Other Instruments, etc.  The execution, delivery and performance by
the Guarantor of this Guarantee will not:

 

(i)                                     contravene, result in any breach of, or
constitute a default under, or result in the creation of any Lien in respect of
any property of the Guarantor under, any indenture, mortgage, deed of trust,
loan, purchase or credit agreement, lease, memorandum or articles of
association, corporate charter or by-laws, or any other agreement, instrument
or license to which the Guarantor is bound

 

 

or subject or by which the
Guarantor or any of its  properties
may be bound or affected,

 

(ii)                                  conflict with or result in a breach of any of
the terms, conditions or provisions of any order, judgment, decree, or ruling
of any court, arbitrator or Governmental Authority applicable to the Guarantor,
or

 

(iii)                               violate any provision of any applicable law
or other rule or regulation of any Governmental Authority applicable to the
Guarantor.

 

(d)                                 Governmental
Authorisations, etc.   No consent, approval or authorisation of, or
registration, filing or declaration with, any Governmental Authority is
required in connection with the execution, delivery or performance by the
Guarantor of this Guarantee, save as may be required under sections 155 through
158, inclusive, of the Companies Act.

 

(e)                                  Pari Passu
Ranking.   The Guarantor’s obligations under this
Guarantee will rank at least pari passu,
without preference or priority, with all of its other outstanding unsecured and
unsubordinated obligations, except for those obligations that are mandatorily
preferred by law and not by reason of contract.

 

(f)                                    Solvency
of Guarantor.  The Guarantor, after giving effect to the
transactions contemplated by this Guarantee, will not be unable to pay its
debts (within the meaning of Section 123(1)(a) or (e) or Section 123(2) of the
Insolvency Act).

 

3.    COVENANTS.

 

3.1.  Covenants in Amended and Restated Note
Purchase Agreement.

 

The Guarantor will comply
with each of the provisions of Section •, Section • and Section • of the Amended and Restated Note Purchase
Agreement in so far as those provisions are expressed to apply to a Subsidiary
or a Guarantor specifically or to any Subsidiary generally.

 

3.2.  Pari
Passu Ranking.

 

The Guarantor shall ensure
that its obligations under this Guarantee will at all times rank at least pari passu in all respects with the claims
of all of its other unsecured creditors save those whose claims are preferred
by any

 

 

bankruptcy, receivership,
insolvency, liquidation or other similar laws of general application.

 

4.    TRANSACTION EXPENSES.

 

The Guarantor will pay all
costs and expenses (including, without limitation, reasonable attorneys’ fees
of a special United States counsel and a special English counsel and, if
reasonably required, other local counsel) incurred by each Holder in connection
with this Guarantee and in connection with any amendments, waivers or consents under
or in respect of this Guarantee (whether or not such amendment, waiver or
consent becomes effective), including, without limitation: (a) the costs and
expenses incurred in enforcing or defending (or determining whether or how to
enforce or defend) any rights under this Guarantee, the Amended and Restated
Note Purchase Agreement, or the Notes or in responding to any subpoena or other
legal process or informal investigative demand issued in connection with this
Guarantee, the Amended and Restated Note Purchase Agreement, or the Notes; and
(b) the costs and expenses, including, without limitation, financial advisors’
and reporting or investigating accountants’ fees, incurred in connection with
the insolvency or bankruptcy of the Guarantor or in connection with any
work-out or restructuring of the transactions contemplated by this Guarantee,
the Amended and Restated Note Purchase Agreement, or the Notes. The Guarantor
will pay, and will save each Holder and hold each Holder harmless from, all
claims in respect of any fees, costs or expenses if any, of brokers and finders
(other than those retained by such Holder).

 

5.    SURVIVAL OF REPRESENTATIONS
AND WARRANTIES; ENTIRE AGREEMENT.

 

All representations and
warranties contained herein shall survive the execution and delivery of this
Guarantee, the purchase or transfer by any Noteholder or other Holder of any
Note or portion thereof or interest therein and the payment of any Note, and
may be relied upon by any Holder, regardless of any investigation made at any time
by or on behalf of any Noteholder or any other Holder (it being understood that
all representations and warranties of the Guarantor contained in this Guarantee
are made only as of the date hereof). 
All statements contained in any certificate or other instrument
delivered by or on behalf of the Guarantor pursuant to this Guarantee or the
Amended and Restated Note Purchase Agreement shall be deemed representations
and warranties of the Guarantor under this Guarantee (and deemed made at the
time of the delivery of such certificate or other instrument if such delivery
is after the date hereof). Subject to the preceding sentence, this Guarantee
embodies the final expression of all of the terms hereof and is a complete and
exclusive statement of those terms.

 

 

6.    AMENDMENT
AND WAIVER.

 

6.1.  Requirements.

 

This Guarantee may be
amended, and the observance of any term hereof may be waived (either
retroactively or prospectively), with (and only with) the written consent of
the Guarantor and the Required Holders except that no such amendment or waiver
may, without written consent of the Holder or Holders of each of the Notes at
the time outstanding affected thereby, (a) change the percentage of the
principal amount of the Notes the Holders of which are required to consent to
any such amendment or waiver, or (b) amend any of Section 1, Section 2 or this
Section 6.

 

6.2.  Solicitation of Holders of Notes.

 

(a)                                 Solicitation.  The Guarantor
will provide each Holder (irrespective of the amount of Notes then owned by it)
with sufficient information, sufficiently far in advance of the date a decision
is required, to enable such Holder to make an informed and considered decision
with respect to any proposed amendment, waiver or consent in respect of any of
the provisions hereof.   The Guarantor
will deliver executed or true and correct copies of each amendment, waiver or
consent effected pursuant to the provisions of this Section 6 to each Holder of
outstanding Notes promptly following the date on which it is executed and
delivered by, or receives the consent or approval of, the requisite Holders.

 

(b)                                 Payment.  The Guarantor
will not directly or indirectly pay or cause to be paid any remuneration,
whether by way of supplemental or additional interest, fee or otherwise, or
grant any security, to any Holder as consideration for or as an inducement to
the entering into by any Holder of any waiver or amendment of any of the terms
and provisions hereof unless such remuneration is concurrently paid, or
security is concurrently granted, on the same terms, ratably to each Holder
holding Notes then outstanding even if such Holder did not consent to such
waiver or amendment.

 

6.3.  Binding
Effect, etc.

 

Any amendment or waiver
consented to as provided in this Section 6 applies equally to all Holders and
the Guarantor without regard to whether any Note held by any Holder has been
marked to indicate such amendment or waiver. 
No such amendment or waiver will extend to or affect any obligation,
covenant, agreement, Default or Event of Default not expressly amended or
waived or impair any right consequent thereon. 
No course of dealing between the Guarantor and any Holder nor any delay
in exercising any rights hereunder or under any

 

 

Note shall operate as a waiver of any rights of such Holder.  As used herein, the term “this Guarantee” and references thereto
shall mean this Guarantee as it may from time to time be amended or
supplemented.

 

6.4.  Notes held by Guarantor, etc.

 

Solely for the purpose of
determining whether Holders holding the requisite percentage of the aggregate
principal amount of Notes then outstanding approved or consented to any
amendment, waiver or consent to be given under this Guarantee, or have directed
the taking of any action provided herein to be taken upon the direction of
Holders holding a specified percentage of the aggregate principal amount of
Notes then outstanding, Notes directly or indirectly owned by the Guarantor,
the Company, any other Subsidiary or any of their respective Affiliates shall
be deemed not to be outstanding.

 

7.    NOTICES.

communications provided for hereunder shall be in writing and sent (a) by

by an internationally-recognized expedited delivery service (charges prepaid),
