INFONET SERVICES CORPORATION

SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN

ARTICLE

Purpose and Background

1.1    Purpose.  The purpose of the Infonet Supplemental Executive Retirement Plan (the “ISERP”) is to provide pension benefits to designated officers and designated key executives of the Employer in addition to pension benefits that may be payable to them under the Infonet Pension Plan and any other retirement plan or agreement under which benefits may be payable with respect to such persons. In addition, the ISERP will also provide designated officers and key executives of the Employer and their spouses and their dependent children with certain post-employment health and medical insurance coverage.

1.2    Effective Date.  The ISERP was originally effective as of January 1, 1993, and was subsequently amended and restated as of January 1, 1997, and July 1, 1998. This amendment and restatement of the ISERP is effective as of October 1, 2000.

1.3    Definitions.  The capitalized terms used herein shall have the meanings set forth in Article XII hereof, unless a different meaning is plainly required by context.

ARTICLE II

Eligibility and Participation

2.1    Commencement of Participation.  An Eligible Employee may become a Participant in the ISERP on or after the later of the Effective Date and the date he executes and returns to the President a Participation Form, provided that at the time such person elects to participate in the ISERP, he is a participant in the Infonet Pension Plan or, in the case of an

employee of an Affiliate, such other pension or retirement plans as are designated by the President in the Participation Form.

2.2    Cessation of Participation.  Except as may otherwise be required pursuant to Article VIIA, a person shall cease to be a Participant in the ISERP upon the completion of the distribution of the Participant’s pension benefits under the ISERP, provided he is not continuing accruals under Section 4.2 of the ISERP. A Participant who ceases to be a participant in the Infonet Pension Plan, or in the case of an employee of an Affiliate, such other pension or retirement plans as are designated by the President in the Participation Form, shall cease pension benefit accruals under the ISERP as of the last day of the Plan Year in which the Participant ceases to participate in the Infonet Pension Plan or such other plan or plans.

ARTICLE III

Eligibility for Pension Benefits

A Participant shall become eligible to commence receiving pension benefits under the ISERP (a) after the Participant’s Separation from Service and (b) after attaining the minimum Deemed Age and the specified sum of Deemed Age plus Deemed Years of Service in the Participant’s Participation Form. However, a Participant who has attained the minimum Deemed Age specified in the Participant’s Participation Form on or prior to July 1, 1998 may elect to have his Lump Sum Value transferred to his account under the IDIP in accordance with the election provided in Section 5.4(b) hereof.

ARTICLE IV

Pension Benefits

4.1    Pension Benefits Generally.  With the exception of a Participant who makes an election under Section 5.4(b) hereof while he is accruing pension benefits under the ISERP to have his Lump Sum Value transferred to his account under the IDIP and subsequently

-2-

has such amount transferred, each Participant, provided that such Participant is eligible to receive benefits under Article III hereof, shall be paid a monthly pension benefit commencing on the first day of the first month following the date of the Participant’s Separation from Service and continuing for the Participant’s lifetime, which benefit shall be equal to any positive difference between (a) a percentage of the Participant’s Qualified Compensation based upon the sum of such Participant’s Deemed Age and Deemed Years of Service as of the date of the Participant’s Separation from Service, all as set forth in the Participant’s Participation Form, and (b) the Participant’s vested accrued monthly benefit under the Infonet Pension Plan, or in the case of an employee of an Affiliate, such other pension or retirement plans as are designated by the President in the Participation Form, assuming that such benefit is payable to the Participant in the form of a single life annuity commencing on the first day of the first month after the date of the Participant’s Separation from Service.

4.2    Participants Electing In-Service Transfers to the IDIP.  In the case of a Participant who makes an election to transfer his Lump Sum Value to his account under the IDIP while in service pursuant to Section 5.4(b) hereof, such Lump Sum Value shall be determined as of the Participant’s Initial IDIP Transfer Date and as of each Annual IDIP Transfer Date thereafter, and finally as of the first day of the first month following the date of the Participant’s Separation from Service. The amount of such Lump Sum Value shall equal the actuarially equivalent value of the following: the difference between the amounts determined pursuant to Section 4.1(a) and Section 4.1(b) of this Article IV, determined as of the applicable IDIP Transfer Date or the first day of the first month following the date of the Participant’s Separation of Service, as the case may be, such difference to be further reduced by the Participant’s Prior Monthly Benefits (if any). Such actuarially equivalent value shall be determined on the basis of

-3-

the definition of Lump Sum Value described in Article XII. If, a Participant, pursuant to Section 5.4(c), amends his election to transfer his Lump Sum Value hereunder to his account under the IDIP, such Lump Sum Value shall be determined in accordance with the preceding sentence, but the Participant shall have the right to have such benefit paid to him or transferred to his account under the IDIP upon his Separation from Service in accordance with Section 5.4(a) hereof, or to have such monthly benefit otherwise paid in accordance with Sections 5.1 or 5.2 hereof.

ARTICLE V

Form of Pension Payments

5.1    Generally.  Subject to Sections 5.2 and 5.4 hereof, pension benefits payable under the ISERP shall be paid to the Participant monthly for the Participant’s life.

5.2    Joint and Survivor Annuity Option.  At least one year prior to the commencement of payment of a Participant’s pension benefits pursuant to Section 5.1 hereof, the Participant may, in lieu of receiving pension benefits in the form described in Section 5.1 hereof, elect to receive benefit payments under the ISERP in the form of a joint and survivor annuity which provides reduced monthly benefits for the lifetime of the Participant with a stipulated percentage elected by the Participant of such reduced amount being payable after the Participant’s death to the spouse to whom the Participant is married as of the date of the Participant’s Separation from Service, for the lifetime of such spouse. No such election shall become effective if the Participant’s Separation from Service occurs within one (1) year of the date of such election; notwithstanding the foregoing, a Participant who marries within the one-year period prior to his Separation from Service may elect a joint and survivor annuity with 60 days following the date of such marriage. The amount of the monthly benefit payable under this option shall be determined by reference to factors such as the Participant’s life expectancy, the life expectancy of the Participant’s spouse, prevailing interest rates and the percentage of the

-4-

Participant’s monthly benefit which is payable after the Participant’s death to the Participant’s spouse, all (except for such percentage, which is selected by the Participant) as determined by the President, such that the value of the joint and survivor annuity provided under this Section 5.2 is the actuarial equivalent of the benefits otherwise payable under Section 5.1 hereof. In determining the monthly amount payable under the joint and survivor annuity option provided under this Section 5.2 with respect to any Participant, the President may rely upon such information as he, in his sole discretion, deems reliable, including but not limited to, the opinion of an enrolled actuary or annuity purchase rates quoted by an insurance company licensed to conduct an insurance business in the State of California.

5.3    Irrevocability of Joint and Survivor Annuity Option.  A Participant’s election of a joint and survivor annuity provided under Section 5.2 hereof is irrevocable after benefit payments have commenced and the monthly amount payable during the lifetime of the Participant shall in no event be adjusted by reason of the death of the Participant’s spouse prior to the death of the Participant, or by reason of the dissolution of the marriage between the Participant and such spouse, or for any other reason, except that a Participant whose marriage is dissolved may designate another beneficiary to receive the pension benefits which would otherwise be payable to the Participant’s former spouse as a joint and survivor annuity provided under Section 5.2 hereof.

5.4    Lump Sum Option.

(a)    In lieu of receiving pension benefits in the form described in either Sections 5.1 or 5.2 hereof, a Participant may elect to have his Lump Sum Value either paid to him in full in cash on the date that such Participant would otherwise commence receiving benefits under Section 5.1 or 5.2 hereof or transferred and credited on the date that such

-5-

Participant would otherwise commence receiving benefits under Sections 5.1 or 5.2 hereof to his account under the IDIP and paid in accordance with his elections under the IDIP. This election must be made at least one (1) year preceding the date on which such Participant would otherwise commence receiving benefits under the ISERP; provided, that no such election shall become effective if the Participant’s Separation from Service occurs within one (1) year of such election.

(b)    For those Participants who attained the minimum Deemed Age on or prior to July 1, 1998, any such Participant may elect, at least one (1) year preceding the date of transfer, to transfer his Lump Sum Value to his account under the IDIP, provided that no such election shall become effective if the Participant’s Separation from Service occurs within one (1) year of the date of such election. Notwithstanding the foregoing, an election made before January 1, 1999, by a Participant who attained the minimum Deemed Age on or prior to July 1, 1998, to transfer his Lump Sum Value to his account under the IDIP need only be made at least six (6) months before the date of transfer and in a calendar year earlier than that in which the date of transfer occurs and shall not become effective if the Participant’s Separation from Service occurs within six (6) months of the date of such election. If a Participant elects to transfer and credit his Lump Sum Value to his account under the IDIP pursuant to either of the preceding two sentences and remains as a Participant at the time of such Participant’s Annual IDIP Transfer Date, his Lump Sum Value, if any, on each such Annual IDIP Transfer Date occurring after his Initial IDIP Transfer Date will be automatically transferred each year to his account under the IDIP, and the final transfer shall occur on the first day of the month following the date of the Participant’s Separation from Service. If a Participant elects to transfer and credit his Lump Sum Value to his account under the IDIP pursuant to this Section 5.4(b), (i) pension benefits under the ISERP shall continue to accrue as set forth in Article IV from and after the Participant’s Initial

-6-

IDIP Transfer Date until his Separation from Service, and (ii) death benefits under Article VI will continue to be payable until the Participant’s Separation from Service.

(c)    Any election to transfer a Participant’s Lump Sum Value to his account under the IDIP pursuant to this Section 5.4 may be amended not later than one (1) year preceding the date of transfer; provided that no such amended election shall become effective if the Participant’s Separation from Service occurs within one (1) year of such amended election.

ARTICLE VI

Death Benefits

In lieu of the pension benefit provided under Article IV, the named Beneficiary of a Participant who dies while he is employed by an Employer (including a Participant who has elected in-service transfers to the IDIP under Section 5.4 (b) hereof) shall be entitled to receive a lump sum benefit equal to two hundred fifty percent (250%) of the Participant’s Qualified Compensation, determined as of the date of such Participant’s death. No death benefit hereunder shall be payable with respect to any Participant who dies after his Separation from Service, except that the spouse of a deceased Participant shall continue to receive pension benefits under the ISERP if the Participant was receiving pension benefits at the date of his death in the form of a joint and survivor annuity.

ARTICLE VII

Disability Benefits

No disability benefits shall be payable under the ISERP, except that a Participant who suffers a Permanent Disability and incurs a Separation from Service shall be entitled to receive pension benefits under the ISERP upon the Participant’s Separation from Service as set forth in Article IV.

-7-

ARTICLE VIIA

Post-Employment Health and Medical Coverage

7A.1    Eligibility.  With respect to Separations from Service which occur on and after October 1, 2000, a Participant who satisfies the requirements of Article III shall be eligible for post-employment health and medical insurance coverage as described in Section 7A.2.

7A.2    Benefits.  The Employer shall provide comprehensive health and medical insurance coverage hereunder consisting of coverage for a Participant, and such Participant’s spouse and the Participant’s dependent children, which coverage shall be not less favorable to the Participant, the Participant’s spouse and the Participant’s dependent children as the health and medical benefit coverage applicable to such Participant immediately prior to the date on which the Participant satisfies the requirements of Section 7A.1. Notwithstanding the foregoing, (a) if any change made by the Employer in health and medical benefits coverage for executive Employees occurs subsequent to the date of the Participant’s Separation from Service and (b) if such change results in superior health and medical insurance coverage for executive Employees than is then applicable to the Participant, the Participant’s spouse and the Participant’s dependents, such superior health and medical benefits coverage, or the equivalent thereof, shall be substituted for the health and medical benefits coverage then applicable to the Participant, the Participant’s spouse and the Participant’s dependents under the ISERP. For purposes of this Article VIIA, “spouse” and “dependent children” shall have the same meaning as defined in the written instrument governing the operation of the health and medical coverage applicable to the Participant at the time such Participant satisfies the requirements of Section 7A.1.

7A.3    Duration of Coverage.  The health and medical insurance coverage provided under this Article VIIA shall be in effect with respect to the Participant from the date such coverage is effective pursuant to Section 7A.1 until the date of the Participant’s death.

-8-

Upon the death of the Participant, coverage for the Participant’s spouse and dependent children shall continue for the lifetime of such spouse. In the event the spouse is not living upon the death of the Participant or if the Participant and the Participant’s spouse die in a common accident, continuation of coverage with respect to the Participant’s dependent children subsequent to the death of the Participant shall be determined in accordance with the terms of the health and medical insurance coverage applicable to the Participant at the time of the Participant’s death.

ARTICLE VIII

Administration

8.1    Authority of the President.  The ISERP shall be administered by the President, who shall have all such powers as are necessary for the operation and administration of the ISERP, or by such other person or persons to whom the President may delegate all or part of the President’s powers or responsibilities hereunder. With respect to all matters pertaining to the ISERP, the President or his designated delegate shall be responsible for the operation and administration of the ISERP and shall have the power in its good faith discretion to interpret the ISERP and all documents relating thereto and to make such other determinations as may be required or appropriate. Each determination by the President or his designated delegate as to any matter respecting the operation and administration of the ISERP and the other provisions of the ISERP shall be made in a nondiscriminatory manner.

8.2    Delegation of Powers; Reliance on Third Parties.  The President may delegate his powers as appropriate and may engage counsel and such clerical, financial, investment, accounting, and other specialized services as he may deem necessary or desirable for the operation and administration of the ISERP. The President shall be entitled to rely upon any opinions, reports or other advice furnished by counsel or other specialists engaged for such

-9-

purpose and, in so relying, shall be fully protected in any action, determination, or mission taken or made in good faith.

8.3    Indemnification.  The Employers shall defend, indemnify and hold harmless the President and the Compensation Committee of the Board of Directors (and each member thereof), and any other person or committee to whom they have delegated any of their responsibilities hereunder, acting in their official capacity as such and not as Participants herein, from any and all claims, losses, damages, expenses (including reasonable attorneys’ fees and expenses) and liabilities (collectively “Liability”) arising from any action, failure to act, or other conduct in their official capacity under the ISERP, except with respect to any Liability which results from an individual’s own gross negligence or willful misconduct.

8.4    President’s Participation.  The President shall be eligible to participate in the ISERP in the same manner as any other employee, provided that the designation of the President as an Eligible Employee or as a Participant and any other action provided herein with respect to the President’s participation in the ISERP shall be taken by the Compensation Committee of the Board of Directors and implemented by the Secretary.

ARTICLE IX

Right to Amend, Modify, Suspend or Terminate Plan

9.1    Amendment or Termination.  By action of the Board of Directors, Infonet may amend, modify, suspend or terminate the ISERP or the Participants’ Participation Forms without further liability to any Participant, Employee, former Employee or any other person. Notwithstanding the preceding sentence, the ISERP and Participants’ Participation Forms may not be amended, modified, suspended or terminated so as to reduce the amount of the pension benefit or post-employment health and medical insurance coverage of a Participant (or such Participant’s spouse and dependent children, as applicable), without the express prior written

-10-

consent of such Participant or, if deceased, such Participant’s spouse. In the event that both the Participant and the Participant’s spouse are deceased, but post-employment health and medical insurance coverage remains in effect with respect to a dependent child or children of the Participant pursuant to Article VIIA hereof, the legal guardian of each such child shall be required to provide the express prior written consent required herein. Upon termination of the ISERP, the President in his sole discretion may pay the Participants the Lump Sum Value of their pension benefits under the ISERP within thirty (30) days after the termination of the ISERP, may cause such amounts to be distributed in accordance with Article V hereof or may in his sole discretion make arrangements for immediate distributions of annuity benefits under the ISERP to Participants. Notwithstanding the preceding sentence, the President may, in his sole discretion, permit a Participant to elect the manner in which such Participant will receive his pension benefits under the ISERP upon termination of the ISERP from among the options set forth in Sections 5.1, 5.2 and 5.4(a) hereof; provided that (i) no payment shall be made pursuant to any such election until one (1) year following the date of such election and (ii) no such election shall become effective if the Participant’s Separation from Service occurs within one (1) year of the date of such election, in which case the Lump Sum Value of the Participant’s pension benefits under the ISERP shall be paid to him within thirty (30) days of the date of his Separation from Service.

9.2    Change in Control Provisions.  During the three-year period immediately following any Change in Control, the Board of Directors may not amend, modify, suspend or terminate the ISERP or a Participant’s Participation Form in any respect with respect to any person who was a Participant in the ISERP on the date of the Change in Control without the express prior written consent of such Participant. For the avoidance of doubt, the provisions of

-11-

Section 9.1 shall apply at all times, both before any Change in Control and following any Change of Control.

ARTICLE X

Claims Procedure

10.1    Filing of Claim.  Any claim for benefits under the ISERP shall be filed in writing with the President or any person or committee designated by the President as the ISERP’s claims official (the “Claims Official”).

10.2    Initial Decision.  If the Claims Official wholly or partially denies the claim, he shall, within a reasonable period of time after receipt of the claim, provide the claimant with written notice of such denial setting forth, in a manner calculated to be understood by the claimant: (a) the specific reason or reasons for such denial, (b) specific reference to the pertinent ISERP provisions on which the denial is based, (c) a description of any additional material or information necessary for the claimant to perfect the claim and an explanation of why such material or information is necessary and (d) an explanation of the ISERP’s claims review procedure.

10.3    Opportunity for Review of Claim.  The Claims Official shall provide each claimant with a reasonable opportunity to appeal a denial of a claim and an opportunity for a full and fair review of such denial. The claimant or his duly authorized representative: (a) may request a review upon written application to the Claims Official, (b) may review pertinent documents and (c) may submit issues and comments to the Claims Official in writing.

10.4    Timing of Request for Review.  The Claims Official may establish such time limits within which a claimant may request review of a denied claim as are reasonable in relation to the nature of the benefit which is the subject of the claim and to other attendant

-12-

circumstances but which, in no event, shall be less than sixty (60) days after receipt by the claimant of written notice of denial of his claim.

10.5    Decision on Review.  The decision by the Claims Official upon his review of a claim shall be made not later than sixty (60) days after receipt by the Claims Official of the request for review, unless special circumstances require an extension of time for processing, in which case a decision shall be rendered as soon as possible, but not later than one hundred and twenty (120) days after receipt of such request for review. The decision on review shall be in writing and shall include specific reasons for the decision written in a manner calculated to be understood by the claimant with specific references to the pertinent ISERP provisions on which the decision is based.

10.6    Authority of Claims Official.  The Claims Official shall have the full power and authority to resolve any questions and settle all controversies that may arise in connection with the ISERP. No Claims Official shall be liable to any person for any action taken or omitted in connection with the interpretation of the ISERP or deciding claims hereunder.

10.7    Authority of President.  The President shall determine, subject to the concurrence of the Compensation Committee of the Board of Directors: (a) the Eligible Employees who shall participate in the ISERP from time to time and (b) when an Eligible Employee shall cease to be eligible.

10.8    Arbitration.  If a Participant elects, any dispute under the ISERP between the Participant and the Participant’s Employer shall be submitted to private and confidential arbitration by a single neutral arbitrator (unless otherwise provided pursuant to this Section 10.8). Subject to the terms of this Section 10.8, the arbitration proceedings shall be held in Los Angeles, California, and shall be governed by the Commercial Arbitration Rules of the American

-13-

Arbitration Association and the arbitrator shall be selected by the Participant and the Participant’s Employer, or, if the Participant and the Employer cannot agree upon an arbitrator, at the Participant’s option, either the arbitrator shall be selected by the American Arbitration Association pursuant to its Rules or the Participant may bring an action in any court having jurisdiction. If the disposition is arbitrated subject to this Section 10.8, the decision of the arbitrator shall be final and binding on the Participant and the Participant’s Employer, and judgment thereon may be entered in any court having jurisdiction. Should either (a) the Employer, its successors or permitted assigns, or any person acting on behalf of the Employer seek to challenge the ISERP or any of its terms in any action, litigation, arbitral or legal proceeding (including, without limitation, pursuant to this Article X), or (b) any Participant or his spouse or dependent children seek to enforce the ISERP or any of its terms in any such action or proceeding, all of the Participant’s and his spouse’s and dependent’s, and the Participant’s Employer’s, costs, including attorneys’ fees and costs, incurred in connection with any such action, litigation or proceeding shall be paid or reimbursed by the Participant’s Employer.

ARTICLE XI

Miscellaneous Provisions

11.1    No Assignment of Benefits.  No pension benefit payable under, or interest in, the ISERP shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, garnishment, or charge, and any attempt to do so shall be void. Any such benefit or interest shall not in any manner be liable for or subject to the debts, contracts, liabilities, engagements, or torts of any Participant or his Beneficiaries. If the President determines that any Participant or Beneficiary has become bankrupt or that any attempt has been made to anticipate, alienate, sell, transfer, assign, pledge, encumber, garnish, or charge

-14-

any pension benefit payable under, or interest in, the ISERP, the President shall hold or apply such benefit or interest or any part thereof to or for the benefit of such Participant or Beneficiary.

11.2    Releases.  In connection with any benefit or benefit payment under the ISERP, or the designation of any Beneficiary or any election or other action taken or to be taken under the ISERP by any Participant or any other person, Infonet, acting through the President or his delegate, may require such consents or releases as the President or his delegate determines to be appropriate, and further may require any such designation, election or other action to be in writing and in a form satisfactory to the President or his delegate.

11.3    No Waiver.  The failure of an Employer, the President or any other person acting on behalf thereof to demand that a Participant or other person claiming rights with respect to a Participant perform any act which such Participant or person is or may be required to perform hereunder shall not constitute a waiver of such requirement or a waiver of the right to require such act. The exercise of or failure to exercise any discretion reserved to an Employer, the President or his delegate, or to grant or deny any benefit to any Participant or other person under the ISERP shall in no way require the Employer, the President or his delegate to similarly exercise or fail to exercise such discretion with respect to any other Participant or person.

11.4    No Contract.  The ISERP is strictly a voluntary undertaking on the part of the Employers and shall not be deemed to constitute a contract or part of a contract between an Employer and any Employee or other person, nor shall it be deemed to give any Employee the right to be retained for any specified period of time in the employ of an Employer or to interfere with the right of an Employer to discharge any Employee at any time, with or without cause, nor shall the ISERP interfere with the right of an Employer to establish the terms and conditions of employment of any Employee.

-15-

11.5    Nature of ISERP Benefits.  The ISERP shall not be “funded” for tax purposes or within the meaning of ERISA. It is intended that the ISERP shall only provide deferred compensation benefits and/or welfare benefits, as the case may be, for a select group of management or highly compensated employees and, therefore, that the ISERP shall not be subject to Parts 2 and 3 of Title I of ERISA, and deferred compensation benefits under the ISERP shall not be subject to Part 4 of Title I of ERISA and welfare benefits under the ISERP shall be exempt from the reporting and disclosure provisions of Part 1 of Title I of ERISA, except for the provision of plan documents to the Secretary of Labor upon request as required by Section 104(a) of ERISA. The Employers shall not, by virtue of any provisions of the ISERP or by any action of any person, be deemed to be trustees or other fiduciaries of any property for any Participant or Beneficiaries, and the liabilities of an Employer to any Participant or his Beneficiary pursuant to the ISERP shall be those of a debtor pursuant only to such contractual obligations as are created by the ISERP; no such obligation of an Employer shall be deemed to be secured by any pledge or other encumbrance on any property of the Employer. Pension benefits and/or premiums or similar amounts paid for the purpose of providing post-employment health and medical insurance coverage under the ISERP shall be payable from the general assets of the Employers or pursuant to such other means as the Employers deem appropriate, and no Participant or other person shall be entitled to look to any source for payment of such pension benefits and/or premiums or similar amounts paid for the purpose of providing post-employment health and medical insurance coverage other than the general assets of the Employers. To the extent that any Participant or Beneficiary acquires a right to receive payment under the ISERP, such right shall be no greater than the right of an unsecured general creditor of the Employers.

-16-

11.6    Governing Law.  The ISERP shall be construed, administered and governed in all respects under and by applicable federal laws and, where state law is applicable, the laws of the State of California.

11.7    Pronouns and Plurality.  The masculine pronoun shall include the feminine pronoun, and the singular shall include the plural where the context so indicates.

11.8    Titles.  Titles are provided herein for convenience of reference only and are not to serve as a basis for interpretation or construction of the ISERP.

11.9    References.  Unless the context clearly indicates to the contrary, a reference to a statute, regulation or document shall be construed as referring to any subsequently enacted, adopted or executed statute, regulation or document.

11.10    Severable Provisions.  The provisions of the ISERP are severable and if any one or more articles, sections, subsections, paragraphs, clauses or provisions of the ISERP is determined to be illegal, indefinite, invalid or otherwise unenforceable, in whole or in part, the remaining provisions, and any partially unenforceable provisions to the extent enforceable in any jurisdiction, shall continue in full force and effect and shall be binding and enforceable.

11.11    Inability to Ascertain Amount of Payment or to Locate Payee.  If an amount payable under the ISERP cannot be ascertained or the person to whom it is payable has not been ascertained or located within the stated time limits under the ISERP and reasonable efforts to do so have been made, then distribution shall be made not later than thirty (30) days after such amount is determined or such person is ascertained or located.

11.12    Minors and Incompetents.  If the President shall determine that any person to whom payment is payable under the ISERP is unable to care for his affairs because of illness or accident, or is a minor, any payment due (unless a prior claim therefore shall have been made

-17-

by a duly appointed guardian, committee or other legal representative) may be paid to the spouse, a child, parent, or brother or sister, or to any person deemed by the President to have incurred expense for such person otherwise entitled to payment, in such manner and proportions as the President may determine in his sole discretion. Any such payment shall be a complete discharge of the liabilities of the Employers, the President and the Board of Directors under the ISERP.

11.13    Payment Not Salary.  Any benefits payable under the ISERP shall not be deemed salary or other compensation to the Employee for the purposes of computing benefits to which he may be entitled under any pension plan or other arrangement of any Employer maintained for the benefit of its employees, unless such pension plan or arrangement provides for inclusion of such amounts as salary or other compensation.

11.14    Withholding.  The Employers shall have the right to make such provisions as they deem necessary or appropriate to satisfy any obligations they may have to withhold federal, state or local income or other taxes incurred by reason of payments or accruals pursuant to the ISERP.

11.15    Successors of the Employers.  The ISERP shall be binding upon and inure to the benefit of the Employers, their successors and assigns and the Participants and their heirs, executors, administrators and legal representatives. In the event that the Employers sell all or substantially all of the assets of their business and the acquiror of such assets assumes the obligations hereunder, the Employers shall be released from any liability imposed herein and shall have no obligation to provide any benefits payable hereunder.

11.16    Other Documents Incorporated by Reference.  Post-employment health and medical insurance coverage pursuant to Article VIIA hereof shall be provided by such insurance

-18-

contracts or through such other arrangements as shall be designated by the President for such purpose, in his sole discretion. Any insurance contracts or other arrangements entered into for the purpose of providing post-employment health and medical insurance coverage pursuant to Article VIIA hereof shall be incorporated herein by reference. The rights and conditions with respect to the benefits payable from such insurance contracts and other arrangements shall be determined from the contracts and written instruments governing such other arrangements.
