EXHIBIT 10(a)    
  

PREAMBLES  

ESTABLISHMENT OF PLAN  

Effective
May 14, 1992, The Dow Chemical Company (the "Company") has adopted the Executive Supplemental Retirement Plan (the "Plan") as an unfunded program of deferred compensation for
executives, which shall include Part A for Non-U.S. Service, Non-Controlled Group Service and/or Non-Covered Controlled Group Service and Part B for a
Select Group of Management or Highly Compensated Employees, Board Members, and Employees Whose Benefits are Statutorily Limited. The terms of this Plan supersede the terms of the Executive
Supplemental Plan in effect prior to the effective date of this Plan. 

Effective
January 1, 2003, Part A shall also include other benefits as specifically set forth in Section 3.04 of Part A. Such benefits are in addition to those provided
under the Key Employee Insurance Program for any Chief Executive Officers of the Company who return to executive management at the request of the Board of Directors after a period of service as a
non-executive Chairman of the Board (hereinafter "Returning CEOs"). 

PURPOSE  

The
Company desires to provide certain of its executives and a select group of management employees with supplemental benefits that might otherwise be provided by The Dow Chemical Company Employees'
Retirement Plan ("ERP"), but for restrictions of the exclusive benefit rule under Section 401(a) of the Internal Revenue Code (the "Code"), the inability to grant past service to highly
compensated Employees without meeting the non-discrimination requirements of Section 401(a)(4) of the Code, and/or the inability to credit service to Employees while employed by a
controlled group member not covered by the ERP, and to restore benefits which are reduced under the ERP and The Dow Chemical Company Salaried Employees' Savings Plan ("SESP") due to current and/or
future statutory limitations and which are not otherwise provided by any other plan maintained by the Company. 

Effective
January 1, 2003, the Company also desires to provide Returning CEOs with benefits in addition to those currently provided by the Key Employee Insurance Program. 

INTERPRETATION AND GOVERNING LAW  

This
Plan is intended to constitute an unfunded program maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated Employees
consistent with the requirements of Sections 201(2), 301(a)(3) and 401(a)(1) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA").

ARTICLE III

RESTRICTED BENEFITS  

	3.01
	RESTRICTION DUE TO INABILITY TO GRANT PAST SERVICE TO

HIGHLY COMPENSATED EMPLOYEES WITHOUT MEETING THE

NON-DISCRIMINATION REQUIREMENTS OF §401(a)(4) OF THE CODE

	(a)
	The
amount of retirement benefits payable under the ERP to certain Employees who transfer from a foreign entity to a U.S. entity covered by the ERP may not include benefits for
service rendered while a non-U.S. Employee. The intent of this Section 3.01 is to provide these Employees, as named by the Plan Administrator, additional benefits equal to the value
of such Employees' accrued benefits under the foreign plans at the time of transfer.

	(b)
	The
Restricted Benefits payable under Subsection (a) above are subject to the following:

	(i)
	Restricted
Benefits shall be calculated under the terms of the ERP in effect on the earlier of (1) termination or (2) Retirement, with the
exception of credited service. Credited service shall be determined according to a method determined by the Plan Administrator.

	(ii)
	If
legally permissible, Participants hereunder shall be required to waive any retirement benefits payable under any foreign plan. If such a waiver is
not legally permissible, the value of any retirement benefits received under the foreign plans shall be deducted from any Restricted Benefits payable hereunder. Such value shall be calculated
according to a method determined by the Plan Administrator.

	(iii)
	A
Participant's vested interest in his or her Restricted Benefit calculated under this Section 3.01 (i.e., vesting percentage) shall be
determined in accordance with the vesting schedule in their current foreign plan. Such vested interest shall be determined by aggregating service earned under the foreign plan and the ERP. In the
event a Participant forfeits all or a portion of his or her Restricted Benefit due to the provisions of this Section 3.01, no other Participant shall acquire any right to such forfeited amount
except as the Company in its discretion shall provide. 

	3.02
	RESTRICTION DUE TO THE EXCLUSIVE

BENEFIT RULE UNDER §401(a) OF THE CODE

	(a)
	The
amount of credited service and compensation used to calculate retirement benefits under the ERP are limited to the credited service and compensation earned while an Employee of
the Company (including all members of the controlled group that have adopted the ERP). The Company, however, transfers Employees to entities that are not members of the controlled group but with which
it is affiliated. The intent of this Section 3.02 is to provide such Employees, as named by the Plan Administrator, with additional benefits equal to the benefits such Employee would have
earned under the ERP for his or her full period of employment with both controlled group and non-controlled group entities.

	(b)
	The
Restricted Benefits payable under Subsection (a) above are subject to the following:

	(i)
	Restricted
Benefits shall be calculated under the ERP formula in effect on the earlier of (1) termination or (2) Retirement, using the
aggregated credited service and compensation earned while an Employee at both controlled and non-controlled group entities. This amount shall be reduced by both the benefit payable under
the ERP and 

60

 

the
value of any retirement benefits payable under any plan of a non-controlled group employer. 

	(ii)
	The
value of any retirement benefits payable under any plan of a non-controlled group employer shall be calculated according to a method
determined by the Plan Administrator. 

	3.03
	RESTRICTION DUE TO EMPLOYMENT BY A MEMBER OF

THE CONTROLLED GROUP NOT COVERED BY THE ERP

	(a)
	The
amount of credited service and compensation used to calculate retirement benefits under the ERP are limited to the credited service and compensation earned while an Employee of
the Company (including all members of the controlled group that have adopted the ERP). However, Employees may be transferred to entities that are members of the controlled group not covered by the
ERP. The intent of this Section 3.03 is to provide such Employees, as named by the Plan Administrator, with additional benefits equal to the benefits such Employee would have earned under the
ERP for his or her full period of employment with both the Company and the member of the controlled group not covered by the ERP.

	(b)
	The
Restricted Benefits payable under Subsection (a) above are subject to the following:

	(i)
	Restricted
Benefits shall be calculated under the ERP formula in effect on the earlier of (1) termination or (2) Retirement, using the
aggregated credited service and compensation earned while an Employee at both the Company and the member of the controlled group not covered by the ERP.
This amount shall be reduced by both the benefit payable under the ERP and the value of any retirement benefits payable under any plan of the member of the controlled group not covered by the ERP.

	(ii)
	The
value of any retirement benefits payable under any plan of the controlled group member not covered by the ERP shall be calculated according to a
method determined by the Plan Administrator. 

	3.04
	ADDITIONAL RESTRICTED BENEFITS TO RETURNING CEOS
	(a)
	The
amount of the additional Restricted Benefit for Returning CEOs is (i) minus (ii) calculated as follows:

	(i)
	The
amount of benefit calculated under the terms of the Key Employee Insurance Program, modified as follows:

	(A)
	using
the highest three years of compensation, whether or not consecutive; and

	(B)
	compensation
for the calendar years 2003 and 2004 shall be the total of the rates established as of each respective March 1 for (1) the Executive Performance Plan target
bonus and (2) the monthly base salary multiplied by twelve, provided that the Returning CEOs do not leave the positions of President and CEO without the prior concurrence of the Board of
Directors, if such departure occurs prior to December 31, 2004.

	MINUS
	

	(ii)
	The
amount of benefit calculated under the terms of the Key Employee Insurance Program without modification. 

	(b)
	The
additional benefit calculated under the terms of this Section 3.04 must be taken in the same form of payment as benefits payable under the Key Employee Insurance Program.

ARTICLE IV

DISTRIBUTION OF RESTRICTED BENEFITS  

	4.01
	PAYMENT OF RESTRICTED BENEFITS

Subject
to Section 4.02, Restricted Benefits shall become payable to the Participant, or if applicable, the Participant's Beneficiary at the time benefits commence under the ERP. 

	(a)
	Restricted
Benefits payable under Section 3.01 may be payable in one of the following forms, as elected by the Participant:

	(i)
	In
the same optional form as the Participant's ERP benefit; or

	(ii)
	If
the lump sum value is less than one hundred thousand dollars ($100,000), in a single lump sum payment. Lump sum value shall be calculated using the
UP-1984 Mortality Table and an eight percent (8%) interest rate. 

	(b)
	Restricted
Benefits payable under Sections 3.02 and 3.03 shall be payable in the same optional form as the Participant's ERP benefit. 

	4.02
	CHANGE IN CONTROL

Change
in Control shall mean a change in control of the Company of a nature that would be required to be reported in response to Item 5(f) of Schedule 14A of Regulation 14A promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), whether or not the Company is then subject to such reporting requirement, provided that, without limitation, a Change in
Control shall be deemed to have occurred if: 

	(a)
	any
individual, partnership, firm, corporation, association, trust, unincorporated organization or other entity, or any syndicate or group deemed to be a person under
Section 14(d)(2) of the Exchange Act, is or becomes the "beneficial owner" (as defined in Rule 13d-3 of the General Rules and Regulations under the Exchange Act), directly or
indirectly, of securities of the Company representing 20% or more
of the combined voting power of the company's then outstanding securities entitled to vote in the election of directors of the Company; or

	(b)
	during
any period of two (2) consecutive years (not including any period prior to the execution of this Plan), individuals who at the beginning of such period constitute the
Board of Directors and any new directors, whose election by the Board of Directors or nomination for election by the company's stockholders was approved by a vote of at least three quarters
(3/4) of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for
any reason to constitute a majority thereof. A change in control shall not be deemed to be a Change in Control for purposes of this Plan if the Board of Directors has approved such change in control
prior to either:

	(i)
	the
occurrence of any of the events described in the foregoing clauses (a) and (b), or

	(ii)
	the
commencement by any person other than the Company of a tender offer for the Common Stock. 

In
the event of such Change of Control, the vested Restricted Benefits under Sections 3.01, 3.02 and 3.03 shall become payable immediately and shall be paid as a single lump sum payment within ninety
(90) days of the Change in Control. The value of such single lump sum payment shall be the actuarial equivalent of the monthly Supplemental Retirement Benefit as of the date of Change of
Control based upon an 8% interest rate and the UP-1984 Mortality Table.

required, written notice of the extension shall be furnished to the claimant prior to the termination of the initial 90-day period. In no event shall such extension exceed a period of
90 days from the end of the initial period. The claimant may make a written request for review of any such denial by the Company within 60 days following the date of such denial. The
claimant shall be entitled to submit such issues or comments, in writing or otherwise, as he or she shall consider relevant to a determination of the claim, and may include a request for a hearing in
person before the Plan Administrator. Prior to submitting his request, the claimant shall be entitled to review such documents as the Company shall agree are pertinent to his claim. The Plan
Administrator shall notify the claimant of its decision in writing no later than 60 days following receipt of the claimant's request, unless specific circumstances require an extension of time
for processing, in which case the Plan Administrator's decision shall be rendered no later than 120 days after receipt of such request for review. The interpretations and construction of the
Plan by the Plan Administrator shall be binding and conclusive on all persons and for all purposes.
Notwithstanding the above, any disagreement may be submitted to the Board of Directors or the Plan Administrator for resolution provided that all interested parties agree to be bound by the decision.
No member of the Board of Directors, Company management, or the Plan Administrator shall be liable to any person for any action taken hereunder except for those actions undertaken with lack of good
faith. 

IN WITNESS WHEREOF, this Plan has been executed at Midland, Michigan, this 14th day of May, 1992.

THE DOW CHEMICAL COMPANY
  RETIREMENT POLICY FOR EMPLOYEE DIRECTORS    
  

As amended, re-adopted in full and restated on March 21, 2003:  

        The following policy shall apply with respect to executive management responsibilities and retirement of employee Directors: 

	1.
	Each
member of the Board of Directors who is an officer or employee shall relinquish job line responsibility upon the later of the following dates:

	(a)
	As
of the first day of the month following the Director's sixtieth birthday; or

	(b)
	If
such an officer or employee shall have received a significant promotion or promotions after his or her fifty-fifth birthday, as of the first day of the month following the fifth
anniversary of the most recent such promotion, but in no event beyond the first day of the month following his or her sixty-fifth birthday. 

	2.
	Each
member of the Board of Directors who is an officer or employee shall have the option of relinquishing his or her job line responsibility on the first of any month after attaining
age sixty, whether or not required to relinquish such responsibility pursuant to Paragraph 1 hereof.

	3.
	Each
person described in Paragraphs 1 or 2 hereof, upon relinquishing said job line responsibility, shall while serving as a Director of the Company remain on the payroll of the
Company as an officer or employee without line responsibility and as a "Decelerating" Director, until the earlier of the following dates, such period of time to be called Deceleration:

	(a)
	The
fifth anniversary of relinquishing said job line responsibility;

	(b)
	The
first day of the month following his or her sixty-fifth birthday;

	(c)
	The
date of his or her death. 

If,
however, a Decelerating Director is then serving as the Chairman of the Board of the Company's Board of Directors, his or her period of Deceleration may, at the discretion of the Board, extend
beyond his or her sixty-fifth birthday, but in no event beyond the fifth anniversary of becoming a Decelerating Director. 

Each
Decelerating Director shall hold himself or herself available for nomination to and service on the Board of Directors at the sole discretion of the Board during the period he or she remains on
the Company's payroll, provided that the Director's health permits performance of such service and unless such other reason acceptable to the Board prevents such service. 

	4.
	For
services performed pursuant to Paragraph 3 hereof, the Company shall compensate such Decelerating Director as follows, until the termination of the period of service as
described in Paragraph 3:

	(a)
	First
year: Ninety percent of Final Pay as a Line Employee;

	(b)
	Second
year: Eighty percent of Final Pay as a Line Employee;

	(c)
	Third
year: Seventy percent of Final Pay as a Line Employee;

	(d)
	Fourth
year: Sixty-five percent of Final Pay as a Line Employee; and

	(e)
	Fifth
year: Sixty percent of Final Pay as a Line Employee. 

70

 

Terms
are defined as follows: 

	(a)
	Final
Pay as a Line Employee—Annualized Base Salary times the sum of 1 plus Performance Award Target Percentage.

	(b)
	Annualized
Base Salary—the monthly salary at the time said Decelerating Director retires from line responsibility as described in Paragraphs 1 and 2 times 12 (or
alternatively if applicable outside the U.S., the number of monthly salaries paid per year).

	(c)
	Performance
Award Target Percentage—the individual target percentage award level from the Company's Performance Award program determined for said Decelerating Director for
the calendar year during which he or she retires from job line responsibility as described in Paragraphs 1 and 2, or its successor programs. 

In
any event, the compensation payable under Paragraph 4 (a) through (e) for any Director shall not be less than the Director's retirement benefit projected through the end of the
fifth year of Deceleration, so long as service continues through five full years of Deceleration, under the applicable Dow defined benefit retirement plan, with the same percent survivor benefit as
provided to other active employees by these plans. During such period of service said Decelerating Director shall also be entitled to participate in the same employee life and accident insurance
programs as he or she was already a participant of as of the date Deceleration began. For purposes of calculating such benefits, Annualized Base Salary shall be used. 

In
the event a Decelerating Director retires or otherwise leaves service as a Decelerating Director prior to the end of the fifth year of the period of service, he or she may receive a lump sum
payment in an amount equal to the net present value of the difference, for the remaining period, between (i) such individual's actual pension retirement benefit under the applicable Dow defined
benefit retirement plans, and (ii) the projected retirement benefit under such plans, assuming service through the end of the fifth year of Deceleration. Under such circumstances, such person
may also receive a current or deferred lump sum payment in an amount equal to the net present value of the difference between (i) the annual compensation payable under Paragraph 4
(a) through (e) for the remaining period, and (ii) the actual annual pension payable for each of such years for the remaining period. The payments and terms of any lump sum under
this paragraph shall be subject to the approval of the Chairman of
the Compensation Committee and the Chairman of the Board (or, the Board of Directors in the event of any action relating to the Chairman of the Board). 

	5.
	Each
such person who shall commence services to the Company pursuant to Paragraph 3 and who retires as an employee shall receive retirement benefits under the applicable Company
retirement plan. If such person is a participant in The Dow Chemical Company Employees' Retirement Plan ("the Retirement Plan"), the Retirement Supplement provided for the resolution adopted by this
Board of Directors on December 8, 1977 ("the Retirement Supplement Resolution"), the Dow Employees' Stock Benefit Plan ("DESBP"), or their successor plans such person is subject, however, to
the following:

	(a)
	Employment
described in Paragraph 3 shall be counted as Credited Service under the Retirement Plan and as Vesting Service under DESBP.

	(b)
	Nonqualified
Compensation, as defined in the Retirement Supplement Resolution, shall be calculated for such person as follows:

	(i)
	The
Company will determine a Theoretical Income, defined as an estimate of the amount that such person's salary and cash bonuses would have been if he
or she had retained line responsibility for each year during such person's period of service as described in Paragraph 3. 

71

 

	(ii)
	The
amount of such Theoretical Income shall be substituted for Average Annual Compensation, as defined in the Retirement Plan, for the purpose of
determining Nonqualified Compensation, upon which a Supplement shall be paid to such person pursuant to the Retirement Supplement Resolution following such person's retirement. 

	(c)
	If
such person is not a member of the Retirement Plan and DESBP but is covered by another retirement plan or plans maintained by the Company or a subsidiary, he or she shall receive
retirement benefits from such other plan or plans. A Supplement pursuant to the Retirement Supplement Resolution may be computed and paid to comply as nearly as practicable with the principles set
forth in (a) and (b) of this paragraph to the extent as may be equitable. 

	6.
	Payments
provided for in Paragraphs 3 and 4 hereof shall be ended if the Executive Committee of the Company determines in its sole judgment, after a hearing at which such person shall
be entitled to appear, that such person has at any time engaged in any activity harmful to the interests of or in competition with the Company or its subsidiaries.

	7.
	Each
member of the Board who is or has served the Company as an officer or employee of the Company shall retire from the Board of Directors no later than the first day of the month
following his or her sixty-fifth birthday, provided however that the Chairman of the Board may serve as a Director until the fifth anniversary of becoming a Decelerating Director pursuant to the
provisions of Paragraph 3 herein.
