                                     Approved and adopted by Board of Directors,
                                                              September 16, 2002

                             GEN-PROBE INCORPORATED
                  CHANGE-IN-CONTROL SEVERANCE COMPENSATION PLAN

                                    Preamble

         The Board of Directors of Gen-Probe Incorporated believes that it is in
the best interest of Gen-Probe (the "Company") to provide additional security to
the Employees of the Company and its subsidiaries (the "Employees") and thereby
induce such individuals to continue in their employment and enhance their
ability to perform effectively and without undue distraction should the Company
be rumored to be or become the target of an attempted acquisition or merger.

         Accordingly, in order to (a) induce the Employees to remain in the
employ of the Company and in consideration for their continuing employment and
(b) facilitate the hiring of new Employees the Company adopts the plan
hereinafter set forth (the "Plan") for the payment of certain Benefits in the
event that any Employee's employment is terminated after a Change in Control, by
the Company without Cause.

         The Plan is an employee welfare benefit plan subject to the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"). This Plan document
is also the summary plan description of the Plan.

         PLEASE NOTE THAT WORDS THAT ARE CAPITALIZED IN THIS PLAN HAVE SPECIAL
DEFINITIONS THAT ARE CONTAINED IN SECTION 8.

                                 Plan Provisions

         1. Termination Following Change in Control.

         1.1 Participation in Plan. An Employee who is not an officer of the
Company shall be entitled to participate in this Plan (a) upon the termination
of his or her employment within 12 months following a Change in Control by the
Company without Cause, provided in any case that the termination occurs within
the period set forth in Section 4.1. In no event shall an Employee's termination
of employment be deemed to be without Cause for purposes of this Plan if such
Employee immediately accepts Employment with the Company's successor or
acquirer, unless he or she is subsequently terminated without Cause by the
successor or acquirer within the 12 months following the Change in Control.

         1.2 Compensation. The compensation payable under the circumstances set
forth in Section 1.1 shall be equal to the amount of the Employee's weekly
salary on the date of the

<PAGE>

Change in Control (the "Weekly Salary") to be paid for the number of weeks
determined pursuant to Section 1.3.

         1.3 Duration of Benefits. The Weekly Salary shall be paid to the
Employee for a period of weeks as set forth below, based on the Employee's
position with the Company on the date of the Change in Control:

         2. Payments Upon Termination. Upon a termination under the
circumstances stated in Section 1.1, the Employee shall be paid as follows:

         2.1 The Company shall pay the Employee the full amount due under his or
her Compensation Plan through the Date of Termination, at the rate in effect at
the time Notice of Termination is given, together with the amount, if any, of
any bonus for a past fiscal year that has not yet been paid to him under any
bonus plan. If the Date of Termination occurs after the end of a fiscal year for
which no bonus has yet been awarded, the Employee will be paid a bonus
calculated on the same basis as the bonus awarded to him/her for the prior
fiscal year, or, if he or she was not eligible to participate in the applicable
bonus plan in the prior fiscal year, his or her

                                       2

<PAGE>

bonus will be calculated at the average rate paid in the prior fiscal year to
Employees of comparable grade level.

         2.2 In lieu of any further salary payment to the Employee for periods
subsequent to the Date of Termination, provided the Employee has executed (and
not revoked within any applicable period) a release of claims against the
Company in a form acceptable to the Company, the Company shall pay, in
accordance with the provisions of Section 2.3 below, as severance pay to him
after the Date of Termination, Weekly Salary calculated as set forth in Sections
1.2 and 1.3.

         2.3 The Employee may elect to receive either (a) the full amount of the
Weekly Salary paid in equal installments every week during the period set forth
in Section 1.3, such payments to commence on the second Friday following the
Date of Termination; or (b) an amount equal to ninety percent (90%) of the
aggregate Weekly Salary to be paid under Section 1.3, paid in one lump sum
within fifteen (15) days following the Date of Termination.

         2.4 The Company shall also pay to the Employee all reasonable legal
fees and expenses incurred by the Employee in successfully seeking to obtain or
enforce any right provided by this Plan.

         2.5 Until the earlier of (a) the period set forth in Section 1.3
following the Date of Termination or (b) the Employee's commencement of full
time employment with a new employer, the Company shall pay on the Employee's
behalf the costs of premiums under the Company's medical and dental plans,
programs or arrangements in which he or she was entitled to participate
immediately prior to the Date of Termination. The Company's payment of any
premiums under this Section 2.5 shall not in any manner extend the applicable
coverage period for the Employee under the Consolidated Omnibus Reconciliation
Act of 1985, as amended ("COBRA").

         2.6 The Employee shall not be required to mitigate the amount of any
payment provided for in Sections 2.2 and 2.5 by seeking other employment or
otherwise, nor shall the amount of any such payment be reduced by any
compensation earned by the Employee as the result of employment by another
employer after the Date of Termination, or otherwise.

         2.7 All amounts payable under this Plan shall be subject to (and
reduced by) any applicable required tax withholdings.

         3. Company's Rights Prior to Change in Control. No provision contained
herein shall affect the Company's right or ability, prior to a Change in
Control, to (1) terminate an Employee's employment at any time, with or without
cause or (2) reduce Employee's compensation (including reduction or elimination
of any bonus compensation). Nothing in this Plan shall in any way require the
Company to provide any benefits prior to a Change in Control, nor shall this
Plan ever be construed in any way as establishing any policies or requirements
for severance benefits for any Employee whose employment with the Company
terminates prior to a Change in Control, nor shall anything in this Plan in any
way affect the Company's right in its absolute discretion to change one or more
benefit plans, including but not limited to pension

                                       3
<PAGE>

plans, dental plans, health care plans, savings plans, bonus plans, vacation pay
plans, disability plans, and the like.

         4. Duration and Amendment.

         4.1 This Plan shall become effective on September 16, 2002 and shall
terminate seven (7) years after such date unless, prior thereto, a Change in
Control shall have occurred, in which case all rights granted hereunder shall be
vested, and the Plan shall continue in effect and shall apply to any termination
of employment that occurs within twelve (12) months after the effective date of
the Change in Control.

         4.2 The Company expressly reserves the right to amend or terminate this
Plan during its term at any time before a Change in Control. The Company
expressly waives the right to amend or terminate this Plan during its term at
any time following a Change in Control in any manner that reduces the benefits
or rights provided hereunder, and the Company acknowledges that the rights of
each Employee hereunder shall be binding and irrevocable upon any Change in
Control. Any purported amendment or termination of such Plan that reduces the
benefits or rights provided hereunder following a Change in Control shall be
ineffective. No Employee shall lose any right hereunder for failing to contest
such a purported amendment or termination.

         5. Successors: Binding Agreement.

         5.1 The Company will require any successor (whether direct or indirect,
by purchase, merger, consolidation or otherwise) to all or substantially all of
the business and/or assets of the Company, to expressly assume and agree to
honor this Plan, if such assumption is legally required to make this Plan
enforceable against the successor.

         5.2 This Plan shall be binding on any successor to the business and/or
assets of the Company that executes and delivers the agreement provided for in
Section 5.1 or that otherwise becomes bound by all the terms and provisions of
this Plan by operation of law. The Company shall promptly notify each Employee
of any succession by purchase, merger, consolidation or otherwise to all or
substantially all the business and/or assets of the Company and shall state
whether or not the successor has executed the agreement required by Section 5.1
and, if so, shall make a copy of such agreement available to each Employee.

         5.3 If the Employee should die after termination and while any amount
would still be payable to him hereunder if he had continued to live, all such
amounts, unless otherwise provided herein, shall be paid in accordance with the
terms of this Plan to his or her devisee, legatee or other designee or, if there
be no such designee, to his or her estate. For this purpose, this Plan shall be
enforceable by the Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees.

         5.4 The Company expressly acknowledges and agrees that each Employee
shall have a contractual right to the rights and benefits provided hereunder,
and the Company expressly waives any right it may have to deny liability for any
breach of its contractual commitment hereunder upon the grounds of lack of
consideration, accord and satisfaction or any similar

                                       4
<PAGE>

defense. In any dispute arising after a Change in Control as to whether an
Employee is entitled to benefits or rights under this Plan, there shall be a
presumption that the Employee is so entitled and the burden of proving otherwise
shall be on the Company or any successor.

         5.5 All benefits to be provided hereunder shall be in addition to any
pension, disability, worker's compensation, other Company benefit plan
distribution, unpaid vacation or other unpaid compensation that the Employee has
at his or her Date of Termination, except that the benefits shall be reduced by
payments under any other severance policy of the Company or under any contract
or arrangement between the Employee and the Company requiring the payment of
benefits upon a termination of employment. Any such policy, contract or
arrangement shall take precedence over this Plan if it provides rights and or
benefits that are, considered in the aggregate, more favorable to the Employee,
than the rights and benefits provided hereunder. Any payment that the Company is
required to make to the Employee under any statue or regulation requiring
payment and/or notice on termination will be deducted from the amount of
benefits payable under this Plan.

         6. Claims Provisions and Governing Law.

         6.1 Claims Procedures.

             (a) It is not necessary to submit a formal claim to receive
benefits payable under this Plan. However, if any person (a "Claimant") believes
that benefits are being denied improperly, that the Plan is not being operated
properly, that fiduciaries of the Plan have breached their duties, or that the
Claimant's legal rights are being violated with respect to the Plan, the
Claimant must file a formal claim, in writing, with the Company. This
requirement applies to all claims that any Claimant has with respect to the
Plan, including claims against fiduciaries and former fiduciaries, except to the
extent the Company determines, in its sole discretion, that it does not have the
power to grant all relief reasonably being sought by the Claimant.

             (b) A formal claim must be filed within 90 days after the date the
Claimant first knew or should have known of the facts on which the claim is
based, unless the Company in writing consents otherwise. The Company shall
provide a Claimant, on request, with a copy of the claims procedures established
under subsection (c).

             (c) The Company has adopted procedures for considering claims
(which are set forth in Appendix A), which it may amend from time to time, as it
sees fit. These procedures shall comply with all applicable legal requirements.
These procedures may provide that final and binding arbitration shall be the
ultimate means of contesting a denied claim (even if the Company or its
delegates have failed to follow the prescribed procedures with respect to the
claim). The right to receive benefits under this Plan is contingent on a
Claimant using the prescribed claims and arbitration procedures to resolve any
claim.

         6.2 Governing Law. This Plan is a welfare plan subject to ERISA and it
shall be interpreted, administered, and enforced in accordance with that law. To
the extent that state law is applicable, the validity, interpretation,
construction and performance of this Plan shall be

                                       5

<PAGE>

governed by the laws of the State of California, notwithstanding the choice of
law principles of that or any other state or country.

         7. Notices. For the purposes of this Plan, notices and all other
communications provided for in the Plan shall be in writing and shall be deemed
to have been duly given when delivered or mailed by certified or registered
mail, return receipt requested, postage prepaid, addressed: (a) if to an
Employee, to his or her latest address as reflected on the Company's employment
records, with a copy to him at his or her place of employment, if known; and (b)
if to the Company, to 10210 Genetic Center Drive, San Diego, California 92121,
Attention: General Counsel, or to such other address as the Company may furnish
to each Employee in writing with specific reference to the Plan and the
importance of the notice, except that notice of change of address shall be
effective only upon receipt.

         8. Administration.

            (a) The Company is responsible for the general administration and
management of the Plan and shall have all powers and duties necessary to fulfill
its responsibilities, including, but not limited to, the discretion to interpret
and apply the Plan and to determine all questions relating to eligibility for
benefits. The Plan shall be interpreted in accordance with its terms and their
intended meanings. However, the Company and all Plan fiduciaries shall have the
discretion to interpret or construe ambiguous, unclear, or implied (but omitted)
terms in any fashion they deem to be appropriate in their sole discretion, and
to make any findings of fact needed in the administration of the Plan. The
validity of any such interpretation, construction, decision, or finding of fact
shall not be given de novo review if challenged in court, by arbitration, or in
any other forum, and shall be upheld unless clearly arbitrary or capricious.

            (b) All actions taken and all determinations made in good faith by
the Company or by Plan fiduciaries will be final and binding on all persons
claiming any interest in or under the Plan. To the extent the Company or any
Plan fiduciary has been granted discretionary authority under the Plan, the
Company's or Plan fiduciary's prior exercise of such authority shall not
obligate it to exercise its authority in a like fashion thereafter.

            (c) If, due to errors in drafting, any Plan provision does not
accurately reflect its intended meaning, as demonstrated by consistent
interpretations or other evidence of intent, or as determined by the Company in
its sole discretion, the provision shall be considered ambiguous and shall be
interpreted by the Company and all Plan fiduciaries in a fashion consistent with
its intent, as determined in the sole discretion of the Company. The Company
shall amend the Plan retroactively to cure any such ambiguity.

            (d) No Plan fiduciary shall have the authority to answer questions
about any pending or final business decision of the Company or any affiliate
that has not been officially announced, to make disclosures about such matters,
or even to discuss them, and no person shall rely on any unauthorized,
unofficial disclosure. Thus, before a decision is officially announced, no
fiduciary is authorized to tell any person, for example, that his or her
employment will not be terminated or that the Company will or will not offer
exit incentives in the future. Nothing in this subsection shall preclude any
fiduciary from fully participating in the consideration, making, or

                                       6
<PAGE>

official announcement of any business decision.

             (e) This Section may not be invoked by any person to require the
Plan to be interpreted in a manner inconsistent with its interpretation by the
Plan Administrator or other Plan fiduciaries.

            9. Definitions. The capitalized terms used in this Plan have the
following meanings for purposes of the Plan:

         9.1 "Cause" means:

             (a) the willful and continued failure by an Employee to

demand for substantial performance is delivered to him by the Company, which
demand specifically identifies the manner in which the Company believes that the
Employee has not substantially performed his or her duties;

             (b) the commission by an Employee of any act of fraud, theft or

the Exchange Act) of securities possessing more than fifty percent (50%) of the
total combined voting power of the Company's outstanding securities pursuant to
a tender or exchange offer for securities of the Company; or

             (b) there is a change in the composition of the Board of Directors

outstanding or by being converted into voting securities of the surviving entity
or another entity) more than 66-2/3% of the combined voting power of the voting
securities of the Company or such surviving entity outstanding immediately after
such merger or consolidation; provided, however, that a merger or consolidation
effected to implement a recapitalization of the Company (or similar transaction)

Company's then outstanding voting securities shall not constitute a Change in
Control.

         9.4 "Date of Termination" means if the Employee's employment is

         10. Miscellaneous.

         10.1 After a Change in Control, no successor to the Company shall

under this Plan. No failure to enforce or waiver by any Employee at any time of
any breach by the Company of, or non-compliance with, any condition or provision
of the Plan to be performed by the Company shall be deemed a waiver of similar
or dissimilar provisions or conditions at the same or at any prior or subsequent
time.

<PAGE>

         10.2 The invalidity or unenforceability of any provision of this Plan
shall not affect the validity or enforceability of any other provision of this
Plan, which shall remain in full force and effect. Any such invalid or

unenforceable provision.

claims stage shall be treated as having been irrevocably waived.

                  Claims Decisions

                  If the claim is granted, the benefits or relief the Claimant
seeks shall be provided. If the claim is wholly or partially denied, the claims
official shall, within 90 days (or a longer period, as described above), provide
the Claimant with written notice of the denial, setting forth, in a manner
calculated to be understood by the Claimant: (1) the specific reason or reasons
for the denial; (2) specific references to the provisions on which the denial is
based; (3) a description of any additional material or information necessary for
the Claimant to perfect the claim, together with an explanation of why the
material or information is necessary; and (4) an explanation of the procedures
for appealing denied claims. If the Claimant can establish that the claims
official has failed to respond to the claim in a timely manner, the Claimant may
treat the claim as having been denied by the claims official.

                  Appeals of Denied Claims

                  Each Claimant shall have the opportunity to appeal the claims
official's denial of a claim in writing to an appeals official appointed by the
Company (which may be a person, committee, or other entity). A Claimant must
appeal a denied claim within 60 days after receipt of written notice of denial
of the claim, or within 60 days after it was due if the Claimant did not receive
it by its due date. The Claimant (or his or her duly authorized representative)
may review pertinent documents in connection with the appeals proceeding and may
present issues and comments in writing. The Claimant may present only the
evidence and theories during the appeal that the Claimant presented during the
initial claims stage, except for information the claims official may have
requested the Claimant to provide to perfect the claim. Any claims that the
Claimant does not pursue in good faith through the appeals stage, such as by
failing to file a timely appeal request, shall be treated as having been
irrevocably waived.

                  Appeals Decisions

                  The decision by the appeals official shall be made not later
than 60 days after the written appeal is received by the Company, unless special
circumstances require an extension of

                                      A-1
<PAGE>

time, in which case a decision shall be rendered as soon as possible, but not
later than 120 days after the appeal was filed, unless the Claimant agrees to a
further extension of time. The appeal decision shall be in writing, shall be set
forth in a manner calculated to be understood by the Claimant, and shall include
specific reasons for the decision, as well as specific references to the
provisions on which the decision is based, if applicable. If a Claimant does not
receive the appeal decision by the date it is due, the Claimant may deem his or
her appeal to have been denied.

                  Procedures

                  The Company shall adopt procedures by which initial claims
shall be considered and appeals shall be resolved; different procedures may be
established for different claims. All procedures shall be designed to afford a
Claimant full and fair consideration of his or her claim.

                  Arbitration of Rejected Appeals

                  If a Claimant has pursued his or her claim through the appeal
stage of these claims procedures, the Claimant may contest the denial of that
claim through arbitration, as described below. In no event shall any denied
claim be subject to resolution by any means (such as in a court of law) other
than arbitration in accordance with the following provisions.

         2.       Arbitration Procedure

                  The Company by establishing the Plan agrees to this provision
for arbitration, and a Claimant shall by that action agree to this provision for
arbitration. Any denied claim under this Plan shall be settled by arbitration
and by one arbitrator in accordance with the applicable rules of the Judicial
Mediation & Arbitration Service ("JAMS") and judgment upon the award rendered by
the arbitrator may be entered in any court having jurisdiction thereof, subject,
however, to the terms of Appendix A. The Company and a Claimant contemplate and
agree that (i) as a consequence of asserting such claim, the Employee will
necessarily incur, as part of his or her damages, his or her attorneys' fees and
costs of arbitration, including but not limited to the administrative fees,
expenses, and arbitrator's fees; (ii) if the Employee is awarded damages, the
arbitrator shall include in that award the consequential damages described
above; and (iii) in no event may the Company recover any of its attorneys' fees
or costs of arbitration, including but not limited to the administration fees,
expenses, and arbitrator's fees, unless the Arbitrator affirmatively and
expressly finds that the Employee commenced the arbitration without probable
cause.

                  For the purposes of any such arbitration, there shall be a
conclusive presumption that there has been a "Change in Control" within the
meaning of Section 9.4 of this Plan, unless (i) the Company agrees to submit the
issue of whether there has been a "Change in Control" to the arbitrator, or (ii)
prior to any award in the arbitration proceeding the Company shall have filed an
action or cross-complaint for, or obtained, a declaratory judgment of a U.S.
federal court in which court proceeding any Employee covered by this Plan is
named as a party, finally determining that there has not been such "Change in
Control." The arbitration hereunder shall be suspended pending such judicial
determination. A Claimant who gives notice to the Company of

                                      A-2

<PAGE>

his or her intention to arbitrate shall by that action be deemed to consent to
be bound by the declaratory judgment issued by such court on the issue of
"Change in Control."

                  Any arbitration hereunder shall be in San Diego, California.
The invalidity or unenforceability of any part of these arbitration procedures
shall not affect the validity of the rest of the procedures.

                                      A-3

                                   APPENDIX B

                             ADDITIONAL INFORMATION

                               RIGHTS UNDER ERISA

                  Each participant in the Plan is entitled to certain rights and
protections under ERISA. ERISA provides that all Plan participants will be
entitled to:

Receive Information About Your Plan and Benefits

1. Examine, without charge, at the Plan administrator's office and at certain
Company offices, all Plan documents including collective bargaining agreements
and copies of all documents filed by the Plan with the U.S. Department of Labor,
and available at the Public Disclosure Room of the Pension and Welfare Benefit
Administration, such as annual reports and Plan descriptions.

2. Obtain, upon written request to the Plan administrator, copies of documents
governing the operation of the Plan, including collective bargaining agreements
and copies of the latest annual report (Form 5500 Series) and updated summary
plan description. The Plan administrator may make a reasonable charge for the
copies.

3. Receive a summary of the Plan's annual financial report. The Plan
administrator is required by law to furnish each participant with a copy of this
summary annual report.

4. Continue health care coverage for the participant, his/her spouse or
dependent if there is a loss of coverage as a result of a qualifying event. The
participant and/or his dependents may have to pay for such coverage. Review the
Company's group health insurance plan and summary plan description on the rules
governing your COBRA continuation coverage rights.

Prudent Actions by Plan Fiduciaries

                  In addition to creating rights for Plan participants, ERISA
imposes duties upon the people who are responsible for the operation of the
employee benefit plan. The people who operate the Plan, called "fiduciaries" of
the Plan, have a duty to do so prudently and in the interest of Plan
participants and beneficiaries. No one, including the Company or any other
person, may fire or otherwise discriminate against a Plan participant in any way
to prevent them from obtaining a welfare benefit or exercising any right under
ERISA.

Enforce Your Rights

                  If a claim for a welfare benefit is denied or ignored, in
whole or in part, the affected Plan participant has a right to know why this was
done, to obtain copies of documents relating to the decision without charge, and
to appeal any denial, all within certain time schedules.

                                      B-1
<PAGE>

                  Under ERISA, there are steps a participant can take to enforce
the above rights. For instance, if a participant requests a copy of plan
documents or the latest annual report from the Plan and does not receive them
within 30 days, he or she may file suit in a Federal court. In such a case, the
court may require the Plan administrator to provide the materials and pay up to
$110 a day until the Participant receives the materials, unless the materials
were not sent because of reasons beyond the control of the Plan administrator.
If it should happen that Plan fiduciaries misuse the Plan's money, or if a
participant is discriminated against for asserting his/her rights, you may seek
assistance from the U.S. Department of Labor.

Assistance with Your Questions

                  If a Plan participant has any questions about your Plan, he or
she should contact the Plan administrator. If a participant should have any
questions about this statement or about his/her rights under ERISA, or if he or
she needs assistance in obtaining documents from the Plan administrator, her or
she should contact the nearest office of the Pension and Welfare Benefits
Administration, U. S. Department of Labor, listed in the telephone directory or
the Division of Technical Assistance and Inquires, Pension and Welfare Benefits
Administration, U.S. Department of Labor, 200 Constitution Avenue N.W.,
Washington, D. C. 20210. He or she may also obtain certain publications about
rights and responsibilities under ERISA by calling the publications hotline or
the Pension and Welfare Benefits Administration.

RETIREMENT BENEFITS

	5.1	 	 Normal Retirement Benefit. An Eligible Director’s annual Normal
Retirement Benefit under this Plan shall be calculated as follows:

		
	 	     (a) With respect to an Eligible Director with less than ten
years of Service, the annual Normal Retirement Benefit shall be the

(ii) if applicable, ten percent (10%) of the Eligible Director’s
Base Retainer for each full year of Service beyond five years up to
a maximum of nine years.
	 
	 	     (b) With respect to an Eligible Director with ten or more
years of Service, the annual Normal Retirement Benefit shall be the
sum of (i) one hundred and ten percent (110%) of the Eligible
Director’s Base Retainer plus, (ii) if applicable, the Chairman

hundred ten percent (110%) of the Base Retainer and the Chairman Retainer
(in the case of an Eligible Director with ten or more years of Service),
as applicable.
	 
	5.3	 	 Special Retirement Benefit. A Director who is not an Eligible Director
is not otherwise entitled to the benefit provided under Section 5.1 (as
limited by Section 5.2).

 

 

3

	 	 	Notwithstanding the foregoing, a Director who has at least five (5) years
of Service as a Director subsequent to his retirement as an Employee, and
who retires from the Board of Directors at or after 70, is eligible to
receive a special retirement benefit hereunder equal to 25% of his Base
Retainer.
	 
	5.4	 	 Early Retirement Benefit. An Eligible Director who elects an Early
Retirement shall receive a benefit computed in accordance with Article
5.1, except that such Early Retirement Benefit shall commence in
accordance with Article VI hereof.

ARTICLE VI

PAYMENT OF RETIREMENT BENEFITS

	6.1 	 	Payment of Benefits. Unless otherwise provided in Section 6.2, all
retirement benefits hereunder shall be payable in monthly installments (on
the fifteenth day of the month) equal to one-twelfth (l/12th) of the
annual amounts determined under this Plan. A Director’s retirement
benefit hereunder, if any, shall be payable for the life of the Director,
commencing on the fifteenth day of the month coinciding with or next
following the later to occur of (i) such Director’s 70th birthday and (ii)
the date on which such Director retires from the Board of Directors;
provided, however, that, with respect to an election to receive an Early
Retirement Benefit, such Benefit shall commence on the fifteenth day of
the month following the Director’s 70th birthday. The Director’s last
payment of retirement benefits hereunder shall be made on the fifteenth
day of the month in which he dies.
	 
	6.2 	 	Payments Rounded to Next Higher Full Dollar. Each monthly payment which
is computed in accordance with this Plan will, if not in whole dollars, be
increased to the next whole dollar.

ARTICLE VII

DEATH BENEFIT

	7.1	 	 Death Benefit. Notwithstanding anything herein to the contrary, in the
event an Eligible Director dies prior to his actual retirement from the
Board of Directors, no death benefit shall be paid hereunder. If an
Eligible Director dies while receiving retirement benefits pursuant to
Article VI, no death benefit shall be paid hereunder.

ARTICLE VIII

FUNDING

	8.1 	 	The Company shall enter into a trust agreement creating an irrevocable
grantor trust for the holding of cash, annuity contracts and/or any other
form of assets as shall be determined by the Board of Directors, for
retirement benefits accrued by the Eligible

 

 

4

	 	 	Directors (whether current or former) under the Plan; provided, however,
that upon the occurrence of a Change of Control Transaction (as defined
in Section 12.2), the Company shall transfer to the trustee of the
foregoing trust the maximum amount of assets estimated to be necessary to
satisfy the Company’s obligations hereunder, as in effect immediately
prior to the Change of Control Transaction; provided, further, that in no
event shall the amount transferred to the trustee of the foregoing trust
be less than the amount of the accrued benefit determined under the same
factors which would be used under the Company’s qualified retirement
plan. Any assets of such trust shall be subject to the claims of
creditors of the Company to the extent set forth in the trust. Eligible
Directors’ (whether current or former) interests in benefits under this
Plan shall only be those of unsecured creditors of the Company.

ARTICLE IX

PLAN ADMINISTRATION

	9.1	 	 The general administration of this Plan and the responsibility for
carrying out the provisions hereof shall be vested in the Compensation
Committee. The Compensation Committee may adopt, subject to the approval
of the Board of Directors, such rules and regulations as it may deem
necessary for the proper administration of this Plan, and its decision in
all matters shall be final, conclusive, and binding.

ARTICLE X

AMENDMENT AND TERMINATION

	10.1	 	 The Board of Directors reserves in its sole and exclusive discretion the
right at any time and from time to time to amend this Plan in any respect
or terminate this Plan without restriction and without the consent of any
Eligible Director, provided, however, that no amendment or termination of
this Plan shall impair the right of any Eligible Director to receive
benefits earned and accrued hereunder prior to such amendment or
termination. The Board of Directors shall not terminate this Plan solely
to accelerate benefits earned and accrued hereunder. Any amounts not
currently payable to an Eligible Director shall revert to the Company in
the event of termination of the Plan.
	 

ARTICLE XI

MISCELLANEOUS PROVISIONS

	11.1	 	 This Plan does not in any way obligate the Company to continue to retain
a Director on the Board of Directors, nor does this Plan limit the right
of the Company to terminate a Director’s service on the Board of
Directors.
	 
	11.2 	 	Non-Alienation of Benefits. No retirement benefit payable hereunder may
be assigned, pledged, mortgaged or hypothecated and to the extent
permitted by law, no such

 

 

5

	 	 	retirement benefit shall be subject to legal process or attachment for
the payment of any claims against any person entitled to receive the
same.
	 
	11.3 	 	Payment to Incompetents. If an Eligible Director entitled to receive any
retirement benefit payments hereunder is deemed by the Compensation
Committee or is adjudged by a court of competent jurisdiction to be
legally incapable of giving valid receipt and discharge for such
retirement benefit, such payments shall be paid to such person or persons
as the Compensation Committee shall designate or to the duly appointed
guardian of such Eligible Director. Such payments shall, to the extent
made, be deemed a complete discharge for such payments under this Plan.
	 
	11.4	 	 Loss of Benefits. At the sole discretion of the Compensation Committee,
and after written notice to the Eligible Director, rights to receive any
retirement benefit under this Plan may be forfeited, suspended, reduced or
terminated in cases of gross misconduct by the Eligible Director, or of
any conduct, activity or competitive occupation which is reasonably deemed
to be prejudicial to the interests of the Company or a subsidiary of the
Company, including but not limited to the utilization or disclosure of
confidential information for gain or otherwise.
	 
	11.5	 	 Noncompetition. An Eligible Director shall forfeit any and all
retirement benefits pursuant to this Plan if said Eligible Director
violates the notice provision of the next paragraph hereof or anywhere in
the United States or outside of the United States, directly or indirectly,
owns, manages, operates, joins or controls, or participates in the
ownership, management, operation or control of, or becomes a director or
an employee of, or a consultant to, any person, firm, or corporation
which competes with the Company; provided, however, that the provisions of
this Article 11.5 shall not apply to investments by the Eligible Director
in shares of stock traded on a national securities exchange or on the
national over-the-counter market which shall have an aggregate market
value, at the time of acquisition, of less than two (2%) percent of the
outstanding shares of such stock.
	 
	 	 	An Eligible Director shall be obligated to give the Company at least
sixty (60) days’ prior written notice, registered or certified mail,
postage prepaid, addressed to the Secretary, Hubbell Incorporated, 584
Derby Milford Road, Orange, Connecticut, 06477, of his intention,
directly or indirectly, to own, manage, operate, join or control, or
participate in the ownership, management, operation or control of, or
become a director or an employee of, or a consultant to, any person,
firm, or corporation, following which, within a period of sixty (60) days
from its receipt of such notice, the Company will mail to the Eligible
Director by registered or certified mail, postage prepaid, a statement of
its opinion as to whether said intention of the Eligible Director
violates this Article 11.5.
	 
	11.6	 	 Withholding. Payments made by the Company under this Plan to any
Eligible Director shall be subject to withholding as shall, at the time
for such payment, be required under any income tax or other laws, whether
of the United States or any other jurisdiction.

 

 

6

	11.7 	 	Expenses. All expenses and costs in connection with the operation of
this Plan shall be borne by the Company.
	 
	11.8 	 	Governing Law. The provisions of this Plan will be construed according
to the laws of the State of Connecticut, excluding the provisions of any
such laws that would require the application of the laws of another
jurisdiction.
	 
	11.9 	 	Gender and Number. The masculine pronoun wherever used herein shall
include the feminine gender and the feminine the masculine and the
singular number as used herein shall include the plural and the plural the
singular unless the context clearly indicates a different meaning.
	 
	11.10 	 	Titles and Headings. The titles to articles and headings of sections of
this Plan are for convenience of reference only and in case of any
conflict, the text of the Plan, rather than such titles and headings,
shall control.

ARTICLE XII

CHANGE OF CONTROL

	12.1	 	 The provisions of Section 12.3 shall become effective immediately upon
the occurrence of a Change of Control (as defined in Section 12.2(a)).
	 
	12.2	 	 (a) “Change of Control” — shall mean any one of the following:

	 	(i)	 	Continuing Directors no longer constitute at
least 2/3 of the Directors;
	 
	 	(ii)	 	any person or group of persons (as defined in
Rule 13d-5 under the Securities Exchange Act of 1934),
together with its affiliates, becomes the beneficial owner,
directly or indirectly, of twenty (20%) percent or more of the
voting power of the then outstanding securities of the Company
entitled to vote for the election of the Company’s directors;
provided that this Article XII shall not apply with respect to
any holding of securities by (A) the trust under a Trust
Indenture dated September 2, 1957 made by Louie E. Roche, (B)
the trust under a Trust Indenture dated August 23, 1957 made
by Harvey Hubbell, and (C) any employee benefit plan (within
the meaning of Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended) maintained by the Company or
any affiliate of the Company;
	 
	 	(iii)	 	the approval by the Company’s stockholders of
the merger or consolidation of the Company with any other
corporation, the sale of substantially all of the assets of
the Company or the liquidation or dissolution of the Company,
unless, in the case of a merger or consolidation, the
incumbent Directors in office immediately prior to such

 

 

7

	 	 	 	merger or consolidation will constitute at least 2/3 of the
Directors of the surviving corporation of such merger or
consolidation and any parent (as such term is defined in Rule
12b-2 under the Securities Exchange Act of 1934) of such
corporation; or
	 
	 	 	(iv)	at least 2/3 of the incumbent Directors in office
immediately prior to any other action proposed to be taken by
