SUPPLEMENTAL EXECUTIVE RETIREMENT AGREEMENT

     WHEREAS, the Connecticut Water Company (hereinafter referred to as “Employer”) and
                     (hereinafter referred to as the “Employee”) entered into a Supplement Executive
Retirement Agreement dated as of                     
 (hereinafter referred to as the “Agreement”);
and

     WHEREAS, the parties wish to amend the Agreement in accordance with the provisions of Section
6.A. thereof;

     NOW THEREFORE, in consideration of the premises and of the mutual covenants and agreements
contained herein, the Agreement is hereby amended as follows:

     The second and third unnumbered paragraphs of Section 1.a. and the second and third unnumbered
paragraphs of Section 1.b. of the Agreement, both as added by the Second Amendment, are deleted and
the following two paragraphs are substituted in each place in lieu thereof:

     “For purposes of the foregoing, ‘Average Earnings’ shall have the meaning set forth in the
Retirement Plan, except that in determining Average Earnings, Annual Earnings (as defined in the
Retirement Plan) shall not be limited to the OBRA ’93 annual compensation limit, the annual
compensation limit imposed under the Economic Growth and Tax Relief Reconciliation Act of 2001
(“EGTRRA”), or any similar limit on annual compensation under Section 401(a)(17) of the Internal
Revenue Code of 1986, as amended (the “Code”), imposed by any future legislation.

     In determining Average Earnings, if the Employee retires under this Agreement on or after

long-term awards or PARSAs be taken into account in determining Average Earnings. The value of
such awards (other than long-term awards or PARSAs) shall be included within Annual Earnings in the
year in which such amounts are finally determined and actually awarded. Such amounts, if credited
to a Performance Share Account, shall not be counted a second time when payment is made from such
account.

 

 

     IN WITNESS WHEREOF, the Employer and the Employee have executed this Amendment as of
                                        , 2007.

Participant shall complete, execute and return to the Committee, an Election Form, with respect to
services performed subsequent to such election, within 30 days after being selected to participate
in the Plan. Any Participant may, on or before December 31, 2007, change his elections with

-6-

 

Article 3

Deferral of Compensation

     3.1 Amount of Deferral. Subject to Section 3.2, each Plan Year a Participant may elect
to defer his Earnings in one percent (1%) increments up to a maximum percentage of twenty-five
percent (25%) of such Earnings or as shall otherwise be determined for each Participant by the
Committee in its sole discretion. Except as otherwise provided herein, any such election shall be
irrevocable.

     3.2 Election to Defer. Except as provided below, each Plan Year a Participant may
make an irrevocable deferral election, by timely delivering an Election Form to the Committee, in
accordance with its rules and procedures, before the end of the Plan Year preceding the Plan Year
for which the election is made. If no such Election Form is timely delivered for a Plan Year, the
Annual Deferral Amount shall be zero for that Plan Year. Such Election Form shall indicate the
form and time at which amounts deferred during such Plan Year are to be distributed. Subject to
the Subsequent Election Limitations, such distribution election shall govern the deferred amounts.

     3.3 Withholding of Annual Deferral Amounts. For each Plan Year, the Annual Deferral
Amount shall be withheld from each regularly scheduled Employer payroll in equal amounts, as
adjusted from time to time for changes in Earnings. Any Earnings not paid in scheduled payroll
shall be withheld at the time the Earnings are or otherwise would be paid to the Participant.

     3.4 Investment of Trust Assets. The trustee of the Trust shall be authorized, upon
written instructions received from the Committee or an investment manager appointed by the
Committee, to invest and reinvest the assets of the Trust in accordance with the applicable Trust
Agreement, including the disposition of stock and reinvestment of the proceeds in one or more
investment vehicles designated by the Committee.

     3.5 Vesting of Deferral and Employer Contributions Accounts. A Participant shall at
all times be 100% vested in his Deferral Account. A Participant’s vested interest in his Employer
Contribution Account shall be determined under Section 4.3.

     3.6 Crediting/Debiting of Account Balances. Amounts shall be credited or debited to a
Participant’s Account in accordance with the following rules:

          3.6.1 Election of Measurement Funds. A Participant, in connection with his initial
deferral election pursuant to Section 2.2, shall elect, on an Election Form, one or more
Measurement Funds (defined in Section 3.6.3) to be used to determine the additional amounts to be
credited to his Account. Once each calendar month, a Participant may change the Measurement
Fund(s) to be used to determine the additional amounts to be credited to his Account, or the
portion of his Account allocated to each previously or newly elected Measurement Fund.

          3.6.2 Proportionate Allocation. In making an election described in Section 3.6.1, the
Participant shall specify on the Election Form, in increments of one percentage point

-7-

 

(1%), the percentage of his Account to be allocated to a Measurement Fund (as if the
Participant was making an investment in that Measurement Fund with that portion of his Account).

          3.6.3 Measurement Funds. The Participant may elect one or more of the measurement
funds selected by the Committee (the “Measurement Funds”) for the purpose of crediting additional
amounts to his Account. The Committee may, in its sole discretion, discontinue, substitute or add
a Measurement Fund at any time.

          3.6.4 Crediting or Debiting Method. The performance of each Measurement Fund shall be
determined by the Committee, in its reasonable discretion, based on the performance of the
Measurement Funds themselves. A Participant’s Deferral Account balance shall be credited or
debited on a daily basis based on the performance of each applicable Measurement Fund as though (i)
a Participant’s Deferral Account was invested in the Measurement Fund(s) selected by the
Participant and (ii) the portion of the Annual Deferral Amount that was actually deferred during
any calendar month was invested in such Measurement Fund(s) in the percentages applicable to such
calendar month, no later than the close of business on the last business day of such calendar
month, at the closing price on such date. A Participant’s Employer Contribution Account balance
shall be credited or debited on a daily basis based on the performance of each applicable
Measurement Fund as though (i) a Participant’s Employer Contribution Account was invested in the
Measurement Fund(s) selected by the Participant and (ii) the portion of the Employer Contribution
that was actually deferred during any calendar month was invested in such Measurement Fund(s) in
the percentages applicable to such calendar month, no later than the close of business on the last
business day of such calendar month, at the closing price on such date.

          3.6.5 No Actual Investment. Notwithstanding any other provision of the Plan to the
contrary, the Measurement Funds are to be used for measurement purposes only, and a Participant’s
election of any such Measurement Fund, the allocation to his Account thereto, the calculation of
additional amounts and the crediting or debiting of such amounts to a Participant’s Account shall
not be considered or construed in any manner as an actual investment of his Account in any such
Measurement Fund. If the Committee or the trustee of the Trust, in its own discretion, decides to
invest funds in any or all of the Measurement Funds, no Participant shall have any rights in or to
such investments. Without limiting the foregoing, a Participant’s Account shall at all times be a
bookkeeping entry only and shall not represent any investment made on his behalf by the Company or
the trustee, and the Participant shall at all times remain an unsecured creditor of the Company.

     3.7 FICA and Other Taxes. In accordance with Section 409A, for each Plan Year in
which an Annual Deferral Amount is being withheld with respect to a Participant, the Participant’s
Employer shall withhold from that portion of the Participant’s compensation that is not being
deferred, in a manner determined by the Employer, the Participant’s share of FICA, if applicable,
and any other applicable employment taxes on such Annual Deferral Amount. If necessary, the
Committee may reduce the Annual Deferral Amount in order to comply with this Section 3.7, provided
such amount does not exceed the aggregate of the FICA amount and the applicable income tax
withholding related to such FICA amount.

-8-

 

     3.8 Withholding on Distributions. The Employer, or the trustee of the Trust, shall
withhold from any payments made to a Participant under the Plan all federal, state and local
income, employment and other taxes that the Employer or the trustee of the Trust, as applicable,
deems necessary or appropriate to be withheld, in connection with such payments, in amounts and in
a manner to be determined in the sole discretion of the Employer or the trustee of the Trust, as
the case may be.

Article 4

Employer Contributions

     4.1 Employer Contributions. Each Participant’s Employer Contribution Account shall be
credited with Employer Contributions equal to no less than ten percent (10%) of the Participant’s
Earnings for the applicable period, as determined by the Committee. Employer Contributions shall
be credited to a Participant’s Account on a monthly basis, but in no event later than fifteen (15)
days after the close of each month. Amounts shall be credited or debited to the Participant’s
Employer Contribution Account in accordance with Section 3.6.

     4.2 Distribution. A Participant’s Employer Contribution Account shall be distributed
at the same time and in the same form as the Participant’s Deferral Account. If a participant did
not properly complete and deliver an Election Form for a Plan year, the vested Employer
Contributions with respect to such Plan Year shall be distributed from the Employer Contribution
Account in a lump sum on the earliest Distribution Event. However, to the extent the Employer
Contribution is distributed pursuant to a Short-Term Payout election under Section 5.1 prior to the
date such Employer Contributions become vested, then such Employer Contribution Account shall be
distributed within 90 days after the Participant becomes vested in such Employer Contributions.

     4.3 Vesting of Employer Contributions. Upon (i) Retiring after attaining age sixty
five (65), (ii) terminating employment on account of death or Disability, (iii) termination of the
Plan or (iv) a Change in Control, a Participant shall become fully vested in his Employer
Contributions Account. A Participant who terminates employment prior to becoming vested under the
preceding sentence shall have, as of the date of such termination, a non-forfeitable right to the
following percentage of Employer Contributions.

	 	 	 	 	 
	Years of Continuous Employment	 	Vested Percentage
	Less than 1
	 	 	0	 
	At least 1 but less than 2
	 	 	20	 
	At least 2 but less than 3
	 	 	40	 
	At least 3 but less than 4
	 	 	60	 
	At least 4 but less than 5
	 	 	80	 
	Upon completion of 5
	 	 	100	 

Upon Terminating Employment, a Participant shall forfeit all unvested Employer Contributions
credited to his Employer Contributions Account. Notwithstanding anything herein to the contrary,
any Employee who is a Participant as of December 31, 2005 shall be credited with any continuous
service with American International Group, Inc., The Chubb Corporation, Swiss Re

-9-

 

or the Affiliates of any of them, provided, that such service ceased immediately prior to the
Participant’s commencement of employment with the Company or any of its Affiliates.
Notwithstanding anything herein to the contrary, the Committee at any time and from time to time
may order that all or any part of a Participant’s Employer Contribution Account shall become vested
and no longer subject to forfeiture, and may order payment of the amounts so vested on the dates
specified in such orders, if the Committee finds such action appropriate in the circumstances.

     4.4 Impact of Reemployment on Vesting. A Participant who is rehired by an Employer
after his Termination of Employment shall not be entitled to amounts forfeited under Section 4.3
prior to his reemployment.

     4.5 FICA and Other Taxes on Employer Contributions. In accordance with Section 409A,
for each Plan Year in which a Participant becomes vested in Employer Contributions credited to his
Employer Contribution Account, the Participant’s Employer shall withhold from that portion of the
Participant’s Earnings that is not being deferred, in a manner determined by the Employer, the
Participant’s share of FICA, if applicable, and any other applicable employment taxes on the
Employer Contributions vesting in such year. If necessary, the Committee may reduce the Annual
Deferral Amount in order to comply with this Section 4.5, provided such amount does not exceed the
aggregate of the FICA amount and the income tax withholding related to such FICA amount.

Article 5

Short-Term Payout and Unforeseeable Financial Emergencies 

     5.1 Short-Term Payout. In connection with each election to defer an Annual Deferral
Amount, a Participant may elect to receive such Annual Deferral Amount as a “Short-Term Payout” by
indicating the specified date to which such amount is to be paid on the Election Form. The
Short-Term Payout shall be a lump sum payment in an amount equal to the Annual Deferral Amount plus
amounts credited or debited pursuant to Section 3.6 on that amount. The Participant’s Account
shall be valued as of December 31st of the Plan Year preceding the Plan Year in which
such distribution shall be made. Short-Term Payouts shall be distributed within 90 days after the
first day of any Plan Year designated by the Participant that is at least five Plan Years after the
Plan Year with respect to which the Annual Deferral Amount is actually deferred.

          5.1.1 Election Changes. Subject to the Subsequent Election Limitations, any
Participant who elects a Short-Term Payout may make another election to further defer the
distribution of such Short-Term Payout by submitting to the Committee either a new Election Form
(during the open enrollment period) or a distribution re-election form (at any time during the Plan
Year).

          5.1.2 Distribution Event Takes Precedence. Should a Distribution Event occur prior to
a scheduled Short-Term Payout, then the provisions of Article 6 shall govern the distribution of
Benefits.

     5.2 Unforeseeable Financial Emergencies. Upon approval by the Committee, a Participant
may withdraw all or any portion of his vested Account balance for an Unforeseeable

-10-

 

Emergency. The amounts distributed with respect to an Unforeseeable Emergency may not exceed
the amounts necessary to satisfy such Unforeseeable Emergency plus amounts necessary to pay taxes
reasonably anticipated as a result of the distribution, after taking into account the extent to
which such hardship is or may be relieved through reimbursement or compensation by insurance or
otherwise or by liquidation of the Participant’s assets (to the extent the liquidation of such
assets would not itself cause severe financial hardship) or by cessation of deferrals under this
Plan. Notwithstanding Section 3.2, if the Committee approves a distribution, the Participant’s
deferrals under the Plan shall cease. A Participant electing a withdrawal under this Section 5.2
may designate the Account or Accounts from which any amounts so distributed shall be taken. If no
election is made, amounts distributed shall be taken first from the Participant’s Deferral Account
and then from the Participant’s Employer Contribution Account (to the extent vested).

Article 6

Benefit Distributions

     6.1 Distribution Event. Except as otherwise provided in Article 10, the Participant’s
Benefit shall be distributed upon the occurrence of a Distribution Event in accordance with the
provisions of this Article 6, subject to the Key Employee Limitation.

          6.1.1 Retirement Benefit. For each Plan Year in which the Participant makes an
election to defer under Section 3.2, the Participant may elect on an Election Form to receive at
Retirement amounts deferred and contributions credited to his Account for such Plan Year in either
(i) a lump sum, or (ii) pursuant to the Annual Installment Method over a period of up to ten years.
If a Participant does not make an affirmative election in any Plan Year, the Participant will be
deemed to have elected a lump sum distribution with respect to amounts deferred that Plan Year.
Subject to the Subsequent Election Limitations, a Participant may change any prior election
annually to an allowable method of distribution by submitting to the Committee either a new
Election Form (during open enrollment) or a distribution re-election form (at any point during the
Plan Year).

          6.1.2 Termination Benefit. If a Participant Terminates Employment, his vested Account
shall be paid in a lump sum.

          6.1.3 Disability Benefit. If a Participant becomes Disabled, either before or after
Retirement or Terminating Employment, his vested Account (or remaining portion thereof) shall be
paid in a lump sum.

          6.1.4 Death Benefit. Upon a Participant’s death, his vested Account shall be paid in
a lump sum to his Beneficiary. However, if a Participant dies before his Benefit is paid in full,
any undistributed Benefit payments shall continue and shall be paid to the Participant’s
Beneficiary on the same schedule as the Benefit would have been paid to the Participant had the
Participant survived.

     6.2 Valuation and Commencement of Benefits Payable in Cash. To the extent applicable,
a Participant’s Account will be valued and Benefits payable in cash shall commence as follows:

-11-

 

          6.2.1 Valuation and Commencement of Lump Sum. The Participant’s Account will be valued
as of the first day of the month following a Distribution Event. Subject to the Key Employee
Limitation, Benefit payments will begin within 90 days following the Distribution Event.

          6.2.2 Valuation and Commencement of Installments. The Participant’s Account will be
valued as of the first day of the month following a Distribution Event. Subject to the Key
Employee Limitation, Benefit payments will begin on the first day of the third month following the
Distribution Event.

     6.3 Automatic Cash-out of Small Accounts. Notwithstanding anything in the Plan or any
Election Form to the contrary, if the value of a Participant’s vested Account is less than $100,000
at any point in time after the date of a Distribution Event, then such Account shall be paid in a
lump sum within 90 days of the Distribution Event or the date the balance in such Account drops
below $100,000. For purposes hereof, the Participant’s Account will be valued as of the first day
of the month following such Distribution Event.

Article 7

Forfeiture

     7.1 Forfeiture Notwithstanding any other provisions of the Plan to the contrary, a
Participant shall forfeit all vested and unvested Employer Contributions if he:

	 	(a)	 	(i) willfully fails (except where due to physical or mental incapacity),
willfully neglects or willfully refuses to substantially perform his duties; (ii)
commits any willful or intentional act with regard to the Employer that has the
effect of injuring the reputation or business of the Employer in a material manner;
(iii) is convicted of, or pleads guilty or nolo contendere to, the
commission of a criminal act that would constitute a felony in the United States; or
(iv) commits an act of fraud, embezzlement or material dishonesty against the
Employer (other than a good faith expense account dispute); or
	 
	 	(b)	 	at any time improperly discloses to others any trade secrets or other
confidential information, including customer lists, relating to the Company or its
Affiliates or to the business of the Company or its Affiliates.

Article 8

Beneficiary Designation

     8.1 Beneficiary. Each Participant shall have the right, at any time, to designate a
Beneficiary to receive any Benefits payable under the Plan upon his death.

     8.2 Beneficiary Designation. A Participant may designate a Beneficiary by completing
a Beneficiary Designation Form, and returning it to the Committee. A Participant shall have the
right to change a Beneficiary by completing, signing and otherwise complying with the terms of the
Beneficiary Designation Form and the Committee’s rules and procedures, as in effect from time to
time. Upon the acceptance by the Committee of a new Beneficiary Designation Form, all Beneficiary
designations previously filed shall be canceled. The

-12-

 

Committee shall be entitled to rely on the last properly executed Beneficiary Designation Form
filed by the Participant and accepted by the Committee prior to his death. No designation or
change in designation of a Beneficiary shall be effective until received and acknowledged in
writing by the Committee.

     8.3 No Beneficiary Designation. If a Participant fails to designate a Beneficiary as
provided in Sections 8.1 and 8.2 or if all designated Beneficiaries predecease the Participant or
die prior to complete distribution of the Participant’s Benefits, the Participant’s surviving
spouse or Domestic Partner, if any, shall be deemed the designated Beneficiary. If the Participant
has no surviving spouse or Domestic Partner, the Benefits remaining to be paid to a Beneficiary
shall be payable to the executor or personal representative of the Participant’s estate.

     8.4 Doubt as to Beneficiary. If the Committee has any doubt as to the proper
Beneficiary to receive payments pursuant to the Plan, the Committee may cause the Participant’s
Employer to withhold such payments until this matter is resolved to the Committee’s satisfaction.

     8.5 Discharge of Obligation. The payment of Benefits under the Plan to a Beneficiary
shall fully and completely discharge all Employers and the Committee from all further obligations
under the Plan with respect to the Participant.

Article 9

Leave of Absence

     9.1 Paid Leave of Absence. A Participant, who is authorized by his Employer to take a
paid leave of absence, shall continue to be considered employed by the Employer, and the Annual
Deferral Amount shall continue to be withheld during such paid leave of absence in accordance with
Section 3.3.

     9.2 Unpaid Leave of Absence. Any Participant who is authorized by his Employer to
take an unpaid leave of absence shall continue to be considered employed by the Employer and upon
the Participant’s return to a paid employment status, deferrals shall resume for the remaining
portion of the Plan Year in which the expiration or return occurs, based on the deferral election,
if any, made for that Plan Year. If no election was made for that Plan Year, no deferral shall be
withheld.

     9.3 Leave of Absence Exceeding Six Months. Notwithstanding Sections 9.1 or 9.2
hereof, if the period of a leave of absence (whether paid or unpaid) exceeds six months and the
Participant’s right to reemployment is not provided either by law or contract, the Participant’s
employment relationship is deemed to terminate on the first day of the month following such
six-month period and the payment of Benefits shall commence in accordance with Article 6.

Article 10

Termination, Amendment and Modification

     10.1 Termination. The Company intends to continue the Plan indefinitely. However, the
Company by action of its Board or a duly authorized committee thereof, in accordance with its
by-laws, reserves the right to terminate the Plan at any time, subject to the limitations on plan

-13-

 

termination imposed by Section 409A. However, no such termination shall deprive any
Participant or Beneficiary of a right accrued under the Plan prior to the date of termination. A
Participant’s entire Account shall then be distributed to the Participant (or Beneficiary) in such
form and on the earliest date permitted under Section 409A.

     10.2 Amendment. The Company may, at any time, amend or modify the Plan in whole or in
part by action of its Board, a committee thereof, or the Committee. However, no such amendment or
modification may operate to (i) decrease the value of a Participant’s Account balance computed as
of the date the amendment or modification is approved, or (ii) effect the timing or form of the
distribution of an Account balance that is scheduled to commence on or before such date in a manner
that would violate Section 409A.

     10.3 Effect of Benefit Payment. The full payment of the Benefit under Article 6,
shall completely discharge all obligations to a Participant and his designated Beneficiaries under
the Plan.

Article 11

Administration

     11.1 Committee Duties. The Plan shall be administered by a Committee, which shall
consist of the Board or such committee, as the Board shall appoint. Members of the Committee may
be Participants. The Committee shall have the discretion and authority to (i) make, amend,
interpret, and enforce all appropriate rules and regulations for the administration of this Plan
and (ii) decide or resolve any and all questions involving the interpretation of the Plan. Any
individual serving on the Committee who is a Participant shall not vote or act on any matter
relating solely to him. When making a determination or calculation, the Committee shall be
entitled to rely on information furnished by a Participant or the Company.

     11.2 Agents. In the administration of the Plan, the Committee may, from time to time,
employ agents and delegate to them such administrative duties as it sees fit (including acting
through a duly appointed representative) and may from time to time consult with counsel who may be
counsel to any Employer.

     11.3 Binding Effect of Decisions. The decision or action of the Committee with
respect to any question arising out of or in connection with the administration, interpretation and
application of the Plan and the rules and regulations promulgated hereunder shall be final and
conclusive and binding upon all persons having any interest in the Plan.

     11.4 Indemnity of Committee. All Employers shall indemnify and hold harmless the
members of the Committee, and any Employee to whom the duties of the Committee may be delegated,
against any and all claims, losses, damages, expenses or liabilities arising from any action or
failure to act with respect to this Plan, except in the case of willful misconduct by the Committee
or any of its members or any such Employee.

     11.5 Employer Information. To enable the Committee to perform its functions, each
Employer shall supply full and timely information to the Committee on all matters relating to the
compensation of its Participants, the date and circumstances of the Retirement, Disability, death

-14-

 

or Termination of Employment of its Participants, and such other pertinent information as the
Committee may reasonably require.

Article 12

Claims Procedures

     12.1 Presentation of Claim. Any Participant or Beneficiary of a deceased Participant
(such Participant or Beneficiary being referred to as a “Claimant”) may deliver to the Committee a
written claim for a determination with respect to the amounts distributable to such Claimant from
the Plan. If such a claim relates to the contents of a notice received by the Claimant, the claim
must be made within 60 days after such notice was received by the Claimant. All other claims must
be made within 180 days of the date on which the event that caused the claim to arise occurred.
The claim must state with particularity the determination desired by the Claimant.

     12.2 Notification of Decision. The Committee shall consider a Claimant’s claim
and make a final decision within 60 days of receipt of such claim based on all comments, documents,
records, and other information submitted. This period may be extended by an additional 60 days for
matters beyond the control of the Plan. The Committee shall notify the Claimant via electronic
means or in writing that (i) the Claimant’s requested determination has been made, and that the
claim has been allowed in full, or (ii) the Committee has reached a conclusion contrary, in whole
or in part, to the Claimant’s requested determination. If any part of the claim is denied, such
notice must set forth in a manner calculated to be understood by the Claimant (i) the specific
reason(s) for the denial of the claim, or any part thereof, (ii) specific reference(s) to pertinent
provisions of the Plan upon which such denial was based, (iii) 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 (iv) an explanation of the claim review procedures
set forth in Sections 12.3 and 12.4.

     12.3 Review of Denied Claim. Within 60 days after receiving a notice from the
Committee that a claim has been denied, in whole or in part, a Claimant (or the Claimant’s duly
authorized representative) may file with a committee designated by the Board to determine such
appeals (the “Appeals Committee”) a written request for a review of the denial of the claim. On
receipt of such an appeal, a Claimant (or the Claimant’s duly authorized representative) will be
given the opportunity to review and receive copies of any documents pertinent to the claim. Not
later than 30 days after the review procedure commences, a Claimant (or the Claimant’s duly
authorized representative) may request a hearing with the Appeals Committee, which the Appeals
Committee, in its sole discretion, may grant.

     12.4 Decision on Review. The Appeals Committee will render a final decision within 60
days of receipt of the appeal, unless special circumstances require an extension of time to 120
days. The Appeals Committee will base its decision on all relevant information submitted by a
Claimant (or the Claimant’s duly authorized representative) without regard to whether such
information was previously submitted or considered. Such decision must be written in a manner
calculated to be understood by the Claimant, and it must contain (i) specific reasons for the
decision, (ii) specific reference(s) to the pertinent Plan provisions upon which the decision was
based, and (iii) such other matters as the Appeals Committee deems relevant.

-15-

 

     12.5 Legal Action. A Claimant’s compliance with the foregoing provisions of this
Article 12 is a mandatory prerequisite to a Claimant’s right to commence any legal action with
respect to any claim for Benefits under this Plan.

Article 13

Trust

     13.1 Establishment of the Trust. The Company shall establish the Trust, and each
Employer shall at least annually transfer over to the Trust such assets as the Employer determines,
in its sole discretion, are necessary to provide, on a present value basis, for its respective
future liabilities created with respect to the Annual Deferral Amounts for such Employer’s
Participants for all periods prior to the transfer, as well as any debits and credits to the
Participants’ Account balances for all periods prior to the transfer, taking into consideration the
value of the assets in the trust at the time of the transfer.

     13.2 Interrelationship of the Plan and the Trust. The provisions of the Plan shall
govern the rights of a Participant to receive distributions pursuant to the Plan. The provisions
of the Trust shall govern the rights of the Employers and the creditors of the Employers to the
assets transferred to the Trust. Each Employer shall at all times remain liable to carry out its
obligations under the Plan.

     13.3 Distributions from the Trust. Each Employer’s obligations under the Plan may be
satisfied with Trust assets distributed pursuant to the terms of the Trust, and any such
distribution shall reduce the Employer’s obligations under the Plan.

Article 14

Miscellaneous

     14.1 Status of Plan. The Plan is intended (i) to be a plan that is not qualified
within the meaning of Code Section 401(a) and is unfunded and is maintained by an employer
primarily for the purpose of providing deferred compensation for a select group of management or
highly compensated employees within the meaning of ERISA Sections 201(2), 301(a)(3) and 401(a)(1),
and (ii) to comply with Section 409A. The Plan shall be administered and interpreted to the extent
possible in a manner consistent with such intent.

     14.2 Unsecured General Creditor. Participants and their Beneficiaries, heirs,
successors and assigns shall have no legal or equitable rights, interests or claims in any property
or assets of an Employer. For purposes of the payment of Benefits under this Plan, any and all of
an Employer’s assets shall be, and remain, the general, unpledged unrestricted assets of the
Employer. An Employer’s obligation under the Plan shall be merely that of an unfunded and
unsecured promise to pay money or distribute Shares, as the case may be, in the future.

     14.3 Employer’s Liability. The Employers shall be jointly and severally liable for
all Benefits under the Plan, provided that the Employers’ liability for the payment of Benefits
shall be defined only by the Plan and related forms. No Employer shall have any obligation to a
Participant under the Plan except as expressly provided in the Plan and related forms.

-16-

 

     14.4 Nonassignability. Neither a Participant nor any other person shall have any
right to commute, sell, assign, transfer, pledge, anticipate, mortgage or otherwise encumber,
transfer, hypothecate, alienate or convey in advance of actual receipt, the amounts, if any,
payable hereunder, or any part thereof, which are, and all rights to which are expressly declared
to be, unassignable and non-transferable. No part of the amounts payable shall, prior to actual
payment, be (i) subject to seizure, attachment, garnishment or sequestration for the payment of any
debts, judgments, alimony or separate maintenance owed by a Participant or any other person, (ii)
transferable by operation of law in the event of a Participant’s or any other person’s bankruptcy
or insolvency, or (iii) transferable to a spouse or Domestic Partner as a result of a property
settlement or otherwise.

     14.5 Not a Contract of Employment. The terms and conditions of the Plan shall not be
deemed to constitute a contract of employment between any Employer and a Participant. Nothing in
this Plan shall be deemed to give a Participant the right to be retained in the service of any
Employer as an Employee, or to interfere with the right of any Employer to discipline or discharge
the Participant at any time.

     14.6 Furnishing Information. A Participant or his Beneficiary will cooperate with the
Committee by furnishing any and all information requested by the Committee and take such other
actions as may be requested in order to facilitate the administration of the Plan and the payments
of Benefits hereunder, including, but not limited to, taking such physical examinations as the
Committee may deem necessary.

     14.7 Terms. Whenever any words are used herein in the masculine, they shall be
constructed as though they were in the feminine in all cases where they would apply, and whenever
any words are used herein in the singular or in the plural, they shall be construed as though they
were used in the plural or the singular, as the case may be, in all cases when they would so apply.

     14.8 Captions. The captions of the articles, sections and paragraphs of the Plan are
for convenience only and shall not control or affect the meaning or construction of any of its
provisions.

     14.9 Governing Law. Subject to ERISA and the Code, the provisions of the Plan shall
be construed and interpreted according to the laws of the State of Delaware without regard to its
conflicts of law principles.

     14.10 Notice. Any notice or filing required or permitted to be given to the Committee
under this Plan shall be sufficient if in writing and hand-delivered, or sent by registered or
certified mail, to the address below:

Allied World Assurance Company (U.S.) Inc.

Supplemental Executive Retirement Plan Committee

100 Summer Street

Boston, Massachusetts 02110

-17-

 

     Such notice shall be deemed given as of the date of delivery or, if delivery is made by mail,
as of the date shown on the postmark on the receipt for registration or certification. Any notice
or filing required or permitted to be given to a Participant under this Plan shall be sufficient if
in writing and hand-delivered, or sent by mail, to the last known address of the Participant.

     14.11 Successors. The provisions of this Plan shall bind and inure to the benefit of
the Participant’s Employer and its successors and assigns and the Participant and the Participant’s
Beneficiaries.

     14.12 Validity. If any provision of this Plan shall be illegal or invalid for any
reason, said illegality or invalidity shall not affect the remaining parts hereof, and the Plan
shall be construed and enforced as if such illegal or invalid provision had never been inserted
herein.

     14.13 Incompetent. If the Committee determines in its discretion that a Benefit under
this Plan is to be paid to a minor, a person declared incompetent or a person incapable of handling
the disposition of that person’s property, the Committee may direct payment of such Benefit to the
guardian, legal representative or person having the case and custody of such minor, incompetent or
incapable person. The Committee may require proof of minority, incompetence, incapacity, or
guardianship, as it may deem appropriate prior to distribution of the Benefit. Any payment of a
Benefit shall be a payment for the account of the Participant and the Participant’s Beneficiary, as
the case may be, and shall be a complete discharge of any liability under the Plan for such payment
amount.

     14.14 Distribution in the Event of Taxation. If the Internal Revenue Service or a
court of competent jurisdiction determines that Plan Benefits are includible in the gross income of
a Participant under Section 409A prior to actual receipt of the Benefits, the Company shall
immediately cause to be distributed to the Participant the Benefits found to be so includible.

     14.15 Insurance. The Employers, on their own behalf or on behalf of the trustee of
the Trust, and, in their sole discretion, may apply for and procure insurance on the life of the
Participant, in such amounts and in such forms as the trustee may choose. The Employers or the
trustee of the Trust, as the case may be, shall be the sole owner and beneficiary of any such
insurance. The Participant shall have no interest whatsoever in any such policy or policies, and
at the request of the Employers shall submit to medical examinations and supply such information
and execute such documents as may be required by the insurance company or companies to whom the
Employers have applied for insurance.

-18-

 

     14.16 Inability to Locate A Participant. It is the responsibility of a Participant to
apprise the Committee of any change in his or her address or the address of any Beneficiary. In
the event that the Committee is unable to locate a Participant or Beneficiary within two years of a
Distribution Event, the Participant’s Account shall be forfeited and amounts returned to the
Company and neither the Participant or any Beneficiary shall have a claim to such Benefits.

     14.17 Coordination with Other Benefits. Benefits provided for a Participant or
Participant’s Beneficiary under the Plan are in addition to any other benefits available to such
Participant under any other plan or program for employees of the Participant’s Employer. The Plan
shall supplement and shall not supersede, modify or amend any other such plan or program, except as
may otherwise be provided.

          IN WITNESS WHEREOF, the Company has signed this Plan document as of this 29th day
of December 2006.
