                     TRUST UNDER THE MATRIA HEALTHCARE, INC.
                     SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN

         THIS TRUST AGREEMENT made as of the 4th day of February, 2003, by and
between MATRIA HEALTHCARE, INC., a Delaware corporation (the "Company"), and
MERRILL LYNCH TRUST COMPANY, FSB (the "Trustee"), a commercial bank or trust
company acceptable to a majority of the Executives (as hereinafter defined);

         WHEREAS, the Company is a party to the Supplemental Executive
Retirement Plans (the "SERPs") listed in Appendix A for the benefit of the
Executives named therein (hereinafter referred to, individually, as an
"Executive" and collectively, as the "Executives");

         WHEREAS, the SERPs require establishment of a trust (hereinafter called
the "Trust") and contribution to the Trust of assets that shall be held therein,
subject to the claims of the Company's creditors in the event of the Company's
Insolvency (as hereinafter defined) until distributed to the Executives under
the terms of the SERPs (the "SERP Obligations");

         WHEREAS, it is the intention of the parties that this Trust shall
constitute an unfunded arrangement and shall not affect the status of the SERPs
as unfunded plans maintained for the purpose of providing deferred compensation
for a select group of management or highly compensated employees for purpose of
Title I of the Employee Retirement Income Security Act of 1974; and

         WHEREAS, it is the intention of the Company to make contributions to
the Trust as required under the terms of the SERPs;

         NOW, THEREFORE, the parties do hereby establish the Trust and agree
that the Trust shall be comprised, held and disposed of as follows:

SECTION 1.        ESTABLISHMENT OF TRUST.

         (a)      The Company hereby deposits with the Trustee in trust
$1,281,713.00, which shall become the principal of the Trust to be held,
administered and disposed of by the Trustee as provided in this Trust Agreement.

         (b)      The Trust hereby established shall be irrevocable.

         (c)      The Trust is intended to be a grantor trust, of which the
Company is the grantor, within the meaning of subpart E, part I, subchapter J,
chapter 1, subtitle A of the Internal Revenue Code of 1986, as amended, and
shall be construed accordingly.

         (d)      The principal of the Trust, and any earnings thereon, shall be
held separate and apart from other funds of the Company and shall be used
exclusively for the uses and purposes of the Company's SERP Obligations and of
the Company's general creditors, as herein set forth. The Executives and their
beneficiaries shall have no preferred claim on, or any beneficial ownership
interest in, any assets of the Trust. Any rights created under the SERPs and
this Trust Agreement shall be mere unsecured contractual rights of the
Executives and their beneficiaries

<PAGE>

against the Company. Any assets held by the Trust will be subject to the claims
of the Company's general creditors under federal and state law in the event of
Insolvency, as defined in Section 3(a) hereof.

         (e)      The Company, in its sole discretion, may at any time, or from
time to time, make additional deposits of cash or other property in Trust with
the Trustee to augment the principal to be held, administered and disposed of by
the trustee, as provided in this Trust Agreement. Neither the Trustee nor any
Executive or beneficiary shall have any right to compel such additional deposits
(except as may be provided in the SERPs).

         (f)      The Trustee shall not be obligated to receive such cash and/or
property unless prior thereto the Trustee has agreed that such cash and/or
property is acceptable to the Trustee and the Trustee has received such
reconciliation, allocation, investment or other information concerning, or
representation with respect to, the cash and/or property as the Trustee may
require. The Trustee shall have no duty or authority to (a) require any deposits
to be made under the SERPs or to the Trustee; (b) compute any amount to be
deposited under the SERPs to the Trustee; or (c) determine whether amounts
received by the Trustee comply with the SERPs. Assets of the Trust may, in the
Trustee's discretion, be held in an account with an affiliate of the Trustee.

SECTION 2.        PAYMENTS OF SERP OBLIGATIONS.

         (a)      Subject to the provisions of Section 2(b) below, at such time
as an Executive is entitled to a distribution from the Trust under the
applicable SERP, he or she shall be entitled to receive from the Trust (i) an
amount in cash equal to the distribution to which he or she is entitled under
the applicable SERP at such time, less (ii) any payments previously made to him
by the Company with respect to such amount pursuant to the terms of the
applicable SERP. The commencement of payments from the Trust shall be
conditioned on the Trustee's prior receipt of a written instrument from the
Executive (or his or her beneficiary) in a form satisfactory to the Trustee
containing representations as to (A) the amount to which the Executive (or his
or her beneficiary) is entitled under the applicable SERP, (B) whether he or she
has requested the payment of such amount from the Company pursuant to the terms
of the applicable SERP, (C) the amount, if any, he or she has received from the
Company under the applicable SERP with respect to such amount, and (D) the
amount to be paid him or her by the Trust (i.e., the difference between (A) and
(C) above). All payments to an Executive (or his or her beneficiary) from the
Trust shall be made in accordance with the provisions of the applicable SERP.
The Trustee shall be fully protected in making any payment in accordance with
the provisions of this Section.

         (b)      Subject to the provisions of this Section 2(b), the Trustee
shall make or commence payment to the Executive (or his or her beneficiary) in
accordance with his or her representations not later than 30 business days after
its receipt thereof; provided, however, that before the Trustee makes or
commences any such payment and not later than 7 business days after its receipt
of the Executive's representations, the Trustee shall request in writing the
Company's agreement that the Executive's representations are accurate with
respect to the amount, fact, and time of payment to him or her. The Trustee
shall enclose with such request a copy of the Executive's representations and
written advice to the Company that it must respond

                                       2

<PAGE>

to the Trustee's request on or before the 20th business day (which date shall be
set forth in such written advice) after the Executive (or his or her
beneficiary) furnished such representations to the Trustee. If the Company, in a
writing delivered to the Trustee, agrees with the Executive's representations in
all respects, or if the Company does not respond to the Trustee's request by the
20th business day deadline, the Trustee shall make payment in accordance with
the Executive's representations. If the Company advises the Trustee in writing
on or before the 20th business day deadline that it does not agree with any or
all of the Executive's representations, the Trustee shall not make a payment to
the Executive for the disputed amount until such time as the Company and the
Executive notify the Trustee in writing that they have settled the dispute under
the claims procedures of the applicable SERP.

         (c)      Unless (contemporaneously with his submission of the written
instrument referred to in Section 2(a) hereof) an Executive furnishes
documentation in form and substance reasonably satisfactory to the Trustee that
no withholding is required with respect to a payment to be made to him from the
Trust, the Trustee may deduct from any such payment any federal, state or local
taxes required by law to be withheld by the Trustee.

         (d)      The Trustee shall provide the Company with written
confirmation of the fact and time of any commencement of payments hereunder
within 10 business days after any payments commence to an Executive. The Company
shall notify the Trustee in the same manner of any payments it commences to make
to an Executive pursuant to the applicable SERP.

         (e)      The Trustee shall be fully protected in making or refraining
from making any payment or any calculations in accordance with the provisions of
this Section 2.

SECTION 3.        TRUSTEE RESPONSIBILITY REGARDING PAYMENT OF SERP OBLIGATIONS
WHEN THE COMPANY IS INSOLVENT.

         (a)      The Trustee shall cease payment of SERP Obligations if the
Company is Insolvent. The Company shall be considered "Insolvent" for purposes
of this Trust Agreement if (i) the Company is unable to pay its debts as they
become due, or (ii) the Company is subject to a pending proceeding as a debtor
under the United States Bankruptcy Code.

         (b)      At all times during the continuance of this Trust, as provided
in Section 1(d) hereof, the principal and income of the Trust shall be subject
to claims of general creditors of the Company under federal and state law, as
set forth below.

                  (i)      The Board of Directors and the Chief Executive
         Officer of the Company (or, if there is no Chief Executive Officer, the
         highest ranking officer) shall have the duty to inform the Trustee in
         writing of the Company's Insolvency. If a person claiming to be a
         creditor of the Company alleges in writing to the Trustee that the
         Company has become Insolvent, the Trustee shall determine whether the
         Company is Insolvent and, pending such determination, the Trustee shall
         discontinue payment of SERP Obligations.

                  (ii)     Unless the Trustee has actual knowledge of the
         Company's Insolvency, or has received notice from the Company or a
         person claiming to be a creditor alleging that the Company is
         Insolvent, the Trustee shall have no duty to inquire whether the
         Company

                                       3

<PAGE>

         is Insolvent. The Trustee may in all events rely on such evidence
         concerning the Company's solvency as may be furnished to the Trustee
         and that provides the Trustee with a reasonable basis for making a
         determination concerning the Company's solvency.

                  (iii)    If at any time the Trustee has determined that the
         Company is Insolvent, the Trustee shall discontinue payments of SERP
         Obligations and shall hold the assets of the Trust for the benefit of
         the Company's general creditors. Nothing in this Trust Agreement shall
         in any way diminish any rights of the Executives or their beneficiaries
         to pursue their rights as general creditors of the Company with respect
         to the Company's obligations under the SERPs or otherwise.

                  (iv)     The Trustee shall resume the payment of SERP
         Obligations in accordance with Section 2 of this Trust Agreement only
         after the Trust has determined that the Company is not Insolvent (or is
         no longer Insolvent).

         (c)      Provided that there are sufficient assets, if the Trustee
discontinues the payment of benefits from the Trust pursuant to Section 3(b)
hereof and subsequently resumes such payments, the first payment following such
discontinuance shall include the aggregate amount of all payments due for the
period of such discontinuance.

SECTION 4.        PAYMENTS TO THE COMPANY. Except as provided in Section 3
hereof, the Company shall have no right or power to direct the Trustee to return
to the Company or to divert to others any of the Trust assets before all payment
of SERP Obligations have been satisfied pursuant to the terms of the SERPs.

SECTION 5.        INVESTMENT AUTHORITY.

         (a)      The Trustee shall invest and reinvest the principal and income
of the Trust as directed by the Company, which directions may be changed from
time to time, all in accordance with procedures established by the Trustee. The
Trustee may limit the categories of assets in which the Trust may be invested.

         (b)      The Trustee may invest in securities (including stock or
rights to acquire stock) or obligations issued by the Company. All rights
associated with assets of the Trust shall be exercised by the Trustee or the
person designated by the Trustee, and shall in no event be exercised by or rest
with Executives, except that voting rights with respect to Trust assets will be
exercised by the Company, unless an investment adviser has been appointed
pursuant to Section 5(e) and voting authority has been delegated to such
investment adviser.

         (c)      The Company shall have the right at any time, and from time to
time in its sole discretion, to substitute assets of equal fair market value for
any asset held by the Trust. This right is exercised by the Company in a
nonfiduciary capacity without the approval or consent of any person in a
fiduciary capacity.

         (d)      The Company may appoint one or more investment managers,
including any entities affiliated with the Trustee, who shall have the power to
manage, acquire or dispose of such portion of the assets of the Trust as the
Company shall determine subject to the following:

                                       4

<PAGE>

                  (i)      An investment manager shall act in accordance with
         the provisions of an investment management agreement entered into
         between it and the Company, an executed copy of which investment
         management agreement shall be filed with the Trustee;

                  (ii)     Each such investment manager must be registered as an
         investment adviser under the investment Advisers Act of 1940, and shall
         provide investment advice on a discretionary or nondiscretionary basis
         with respect to that portion of the assets of the Trust as the Company
         shall specify from time to time by written direction(s) to the Trustee;

                  (iii)    The indicia of ownership of the assets of the Trust
         shall be held by the Trustee at all times;

                  (iv)     Any entity affiliated with the Trustee may act as
         broker or dealer to execute transactions, including the purchase of any
         securities directly distributed, underwritten, or issued by an entity
         affiliated with the Trustee, at standard commission rates, mark-ups or
         concessions, and to provide other management or investment services
         with respect to such trust, including the custody of assets;

                  (v)      Any direction given to the Trustee by an investment
         manager shall be given in writing or given orally and confirmed in
         writing as soon as practicable. Alternatively, an investment manager
         may provide investment instructions directly to the broker or dealer
         and receipt by the Trustee of a confirmation of the transaction from
         the broker or dealer shall be conclusive evidence of such transactions.
         In either case, the Trustee shall have the authority within 24 hours of
         receipt of such direction from the investment manager or confirmation
         of a transaction to instruct the investment manager to rescind the
         transaction if the Trustee finds that the investment is inconsistent
         with its operational or administrative requirements; and

                  (vi)     The Trustee may pay any such investment manager for
         any such services from the assets at the Trust without reduction for
         any fees or compensation paid to the Trustee for its services as
         trustee.

         (e)      Notwithstanding any other provision of the Agreement, with
respect to the investment of the assets of the Trust managed by an investment
manager, the Trustee shall have only the duty to follow the directions of the
investment manager and the Trustee shall not be liable to anyone:

                  (i)      For an act or omission of the investment manager with
         respect to the investment of such assets;

                  (ii)     For failing to act with respect to the investment of
         such assets absent direction from the investment manager; or

                  (iii)    For failing to invest, periodically review or
         otherwise deal with the investment of such assets.

                                       5

<PAGE>

                  (iv)     In the event the Company is "Insolvent" for purposes
         of Section 3 and the Company fails to provide effective investment
         instructions to the Trustee as provided in Section 5(a), the Trustee
         may appoint one or more investment advisers who are registered as
         investment advisers under the Investment Advisers Act of 1940, who may
         be affiliates of the Trustee, to provide investment advice on a
         discretionary or non-discretionary basis with respect to all or a
         specified portion of the assets of the Trust.

         (f)      Subject to Sections 5(a) and (d), the Trustee, or the
Trustee's designee, is authorized and empowered:

                  (i)      To invest and reinvest Trust assets, together with
         the income therefrom, in common stock, preferred stock, convertible
         preferred stock, bonds, debentures, convertible debentures and bonds,
         mortgages, notes, commercial paper and other evidences of indebtedness
         (including those issued by the Trustee), shares of mutual funds (which
         funds may be sponsored, managed or offered by an affiliate of the
         Trustee), guaranteed investment contracts, bank investment contracts,
         other securities, policies of life insurance, annuity contracts,
         options, options to buy or sell securities or other assets, and all
         other property of any type (personal, real or mixed, and tangible or
         intangible);

                  (ii)     To deposit or invest all or any part of the assets of
         the Trust in savings accounts or certificates of deposit or other
         deposits in a bank or savings and loan association or other depository
         institution, including the Trustee or any of its affiliates, provided
         with respect to such deposits with the Trustee or an affiliate the
         deposits bear a reasonable interest rate;

                  (iii)    To hold, manage, improve, repair and control all
         property, real or personal, forming part of the Trust; to sell, convey,
         transfer, exchange, partition, lease for any term, even extending
         beyond the duration of this Trust, and otherwise dispose of the same
         from time to time;

                  (iv)     To hold in cash, without liability for interest, such
         portion of the Trust as is pending investments, or payment of expenses,
         or the distribution of benefits;

                  (v)      To take such actions as may be necessary or desirable
         to protect the Trust from loss due to the default on mortgages held in
         the Trust including the appointment of agents or trustees in such other
         jurisdictions as may seem desirable, to transfer property to such
         agents or trustees, to grant to such agents such powers as are
         necessary or desirable to protect the Trust, to direct such agent or
         trustee, or to delegate such power to direct, and to remove such agent
         or trustee;

                  (vi)     To settle, compromise or abandon all claims and
         demands in favor of or against the Trust;

                  (vii)    To exercise all of the further rights, powers,
         options and privileges granted, provided for, or vested in trustees
         generally under the laws of the state in which the Trustee has its
         principal place of business so that the powers conferred upon the

                                       6

<PAGE>

         Trustee herein shall not be in limitation of any authority conferred by
         law, but shall be in addition thereto;

                  (viii)   To borrow money from any source and to execute
         promissory notes, mortgages or other obligations and to pledge or
         mortgage any trust assets as security; and

                  (ix)     To maintain accounts at, execute transactions
         through, and lend on an adequately secured basis stocks, bonds or other
         securities to, any brokerage or other firm, including any firm which is
         an affiliate of the Trustee.

         (g)      The Trustee and the Company shall agree to such other
investment powers of the Trustee as are necessary for the establishment and
proper administration of the Trust; provided; however, that such investment
powers are standard among the industry and do not conflict with the terms of the
Trust; as set forth herein.

SECTION 6.        ADDITIONAL POWERS OF THE TRUSTEE. To the extent necessary or
which it deems appropriate to implement its powers under Section 5 or otherwise
to fulfill any of its duties and responsibilities as the Trustee of the Trust,
the Trustee shall have the following additional powers and authority:

         (a)      To register securities, or any other property, in its name or
in the name of any nominee, including the name of any affiliate or the nominee
name designated by any affiliate, with or without indication of the capacity in
which property shall be held, or to hold securities in bearer form and to
deposit any securities or other property in a depository or clearing
corporation;

         (b)      To designate and engage the services of, and to delegate
powers and responsibilities to, such agents, representatives, advisers, counsel
and accountants as the Trustee considers necessary or appropriate, any of whom
may be an affiliate of the Trustee or a person who renders services to such an
affiliate, and, as part of its expenses under this Trust Agreement, to pay their
reasonable expenses and compensation;

         (c)      To make, execute and deliver, as the Trustee, any and all
deeds, leases, mortgages, conveyances, waivers, releases or other instruments in
writing necessary or appropriate for the accomplishment of any of the powers
listed in this Trust Agreement; and

         (d)      Generally to do all other acts which the Trustee deems
necessary or appropriate for the protection of the Trust.

SECTION 7.        DISPOSITION OF INCOME. During the term of this Trust, all
income received by the Trust, net of applicable expenses and taxes not paid by
the Company, shall be accumulated and reinvested.

SECTION 8.        ACCOUNTING BY THE TRUSTEE. The Trustee shall keep accurate and
detailed records of all investments, receipts, disbursements and all other
transactions required to be made, including such specific records as shall be
agreed upon in writing between the Company and the Trustee. Within one hundred
twenty (120) days following the close of each calendar year and within thirty
(30) days after any removal of resignation of the Trustee, the Trustee shall
deliver

                                       7

<PAGE>

to the Company a written account of its administration of the Trust during such
year or during the period from the close of the last preceding year to the date
of such removal or resignation, setting forth all investments, receipts,
disbursements and other transactions effected by it, including a description of
all securities and investments purchased and sold with the cost or net proceeds
of such purchases or sales (accrued interest paid or receivable being shown
separately), and showing all cash, securities and other property held in the
Trust at the end of such year or as of the date of such removal or resignation,
as the case may be. The Trustee may satisfy its obligation under this Section 8
by rendering to the Company monthly statements setting forth the information
required by this Section separately for the month covered by the statement.

SECTION 9.        RESPONSIBILITY OF THE TRUSTEE.

         (a)      The Trustee shall act with the care, skill, prudence and
diligence under the circumstances then prevailing that a prudent person acting
in like capacity and familiar with such matters would use in the conduct of an
enterprise of a like character and with like aims; provided, however, that the
Trustee shall incur no liability to any person for any action taken pursuant to
a direction, request or approval given by the Company which is contemplated by,
and in conformity with, the terms of the SERPs or this Trust Agreement and is
given in writing by the Company or in such other manner prescribed by the
Trustee. The Trustee shall also incur no liability to any person for any failure
to act in the absence of direction, request or approval from the Company which
is contemplated by, and in conformity with, the terms of this Trust Agreement,
unless such failure to act constitutes gross negligence on the part of the
Trustee. In the event of a dispute between the Company and a party, the Trustee
may apply to a court of competent jurisdiction to resolve the dispute.

         (b)      If the Trustee undertakes or defends any litigation arising in
connection with this Trust, the Company agrees to indemnify the Trustee against
the Trustee's costs, expenses and liability (including, without limitation,
attorney's fees and expenses) relating thereto and to be primarily liable for
such payments. If the Company does not pay such costs, expenses and liabilities
in a reasonably timely manner, the Trustee may obtain payment from the Trust. To
the extent costs, expenses and liabilities are paid from the Trust, the Trustee,
on behalf of the Trust, shall make a claim for reimbursement of such amounts
from the Company, and the Company shall, as soon as practicable after receipt of
a notice of a claim for reimbursement from the Trustee, deposit such amounts in
the Trust.

         (c)      The Trustee may consult with legal counsel (who may be counsel
for the Company generally) with respect to any of its duties or obligations
hereunder.

         (d)      The Trustee may hire agents, accountants, actuaries,
investment advisors, financial consultants or other professionals to assist it
in performing any of its duties or obligations hereunder.

         (e)      The Trustee shall have, without exclusion, all powers
conferred the Trustee by applicable law, unless expressly provided otherwise
herein; provided, however, that if an insurance policy is held as an asset of
the Trust, the Trustee shall have no power to name a beneficiary of the policy
other than the Trust, to assign the policy (as distinct from conversion of

                                       8

<PAGE>

the policy to a different form) other than to a successor Trustee, or to loan to
any person the proceeds of any borrowing against such policy.

         (f)      However, notwithstanding the provisions of Section 9(e) above,
the Trustee may loan to the Company the proceeds of any borrowing against an
insurance policy held as an asset of the Trust.

         (g)      Notwithstanding any powers granted to the Trustee pursuant to
this Trust Agreement or to applicable law, the Trustee shall not have any power
that could give this Trust the objective of carrying on a business and dividing
the gains therefrom, within the meaning of Section 301.7701-2 of the Procedure
and Administrative Regulations promulgated pursuant to the Internal Revenue Code
of 1986, as amended.

SECTION 10.       COMPENSATION AND EXPENSES OF THE TRUSTEE. The Company shall
pay all administrative and Trustee's fees and expenses. If not so paid, the fees
and expenses shall be paid from the Trust. To the extent fees and expenses are
