                      SECOND AMENDMENT TO CREDIT AGREEMENT

       THIS SECOND AMENDMENT TO CREDIT AGREEMENT, dated as of the 19th day of
January, 2000 (this "Amendment"), is made among MATRIA HEALTHCARE, INC., a
Delaware corporation (the "Borrower"), the Lenders (as defined in the Credit
Agreement referred to below), and FIRST UNION NATIONAL BANK, as administrative
agent for the Lenders (in such capacity, the "Administrative Agent").

                                    RECITALS

       A.  The Borrower, certain banks and other financial institutions, the
Administrative Agent, and Harris Trust and Savings Bank, as Co-Agent, are
parties to a Credit Agreement, dated as of January 19, 1999 (as amended, the
"Credit Agreement"), providing for the availability of certain credit facilities
to the Borrower upon the terms and conditions set forth therein. Capitalized
terms used herein without definition shall have the meanings given to them in
the Credit Agreement.

       B.  The Borrower and the Lenders have agreed to amend the Credit
Agreement upon the terms and conditions set forth herein.

                             STATEMENT OF AGREEMENT

       NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

       1.  Defined Terms. The definition of "Required Lenders" in Section 1.1 of
the Credit Agreement is hereby amended and restated in its entirety as follows
(provided that for purposes of Section 8 of this Amendment, the term "Required
Lenders" shall mean all of the Lenders):

       "'Required Lenders' shall mean the Lenders holding outstanding Loans,
       Letter of Credit Exposure, participations in outstanding Swingline Loans
       and Unutilized Revolving Credit Commitments (or, after the termination of
       the Revolving Credit Commitments, outstanding Loans, Letter of Credit
       Exposure and participations in outstanding Swingline Loans) representing
       greater than sixty-six and two-thirds percent (66-2/3%) of the aggregate
       at such time of all outstanding Loans, Letter of Credit Exposure,
       participations in outstanding Swingline Loans and Unutilized Revolving
       Credit Commitments (or, after the termination of the Revolving Credit
       Commitments, the aggregate at such time of all outstanding Loans, Letter
       of Credit Exposure and participations in outstanding Swingline Loans);
       provided that if at any time any one Lender would otherwise constitute
       the "Required Lenders" as provided hereinabove, then "Required Lenders"
       shall mean such Lender together with any one other Lender. For purposes
       of any determination of the "Required Lenders," the aggregate

<PAGE>   2
     outstanding Swingline Loans held by the Swingline Lender shall be
     calculated net of participations therein purchased by the other Lenders
     pursuant to the terms hereof."

     2.      Representations and Warranties.  The Borrower hereby represents and
warrants as follows:

     (a)     Each of the representations and warranties contained in the Credit
Agreement and in the other Credit Documents will be true and correct on and as
of the Amendment Effective Date (as hereinafter defined) and after giving effect
to this Amendment with the same effect as if made on and as of such date (except
to the extent any such representation or warranty is expressly stated to have
been made as of a specific date, in which case such representation or warranty
is true and correct as of such date).

     (b)     On and as of the Amendment Effective Date and after giving effect
to this Amendment, no Default or Event of Default will have occurred and be
continuing.

     3.      Effect of Amendment.  From and after the effective date of the
amendments to the Credit Agreement set forth herein, all references to the
Credit Agreement set forth in any other Credit Document or other agreement or
instrument shall, unless otherwise specifically provided, be references to the
Credit Agreement as amended by this Amendment and as may be further amended,
modified, restated or supplemented from time to time. This Amendment is limited
as specified and shall not constitute or be deemed to constitute an amendment,
modification or waiver of any provision of the Credit Agreement except as
expressly set forth herein. Except as expressly amended hereby, the Credit
Agreement shall remain in full force and effect in accordance with its terms.

     4.      Governing Law.  This Amendment shall be governed by and construed
and enforced in accordance with the laws of the State of Georgia (without regard
to the conflicts of law provisions thereof).

     5.      Severability.  To the extent any provision of this Amendment is
prohibited by or invalid under the applicable law of any jurisdiction, such
provision shall be ineffective only to the extent of such prohibition or
invalidity and only in any such jurisdiction, without prohibiting or
invalidating such provision in any other jurisdiction or the remaining
provisions of this Amendment in any jurisdiction.

     6.      Successors and Assigns.  This Amendment shall be binding upon,
inure to the benefit of and be enforceable by the respective successors and
assigns of the parties hereto.

     7.      Construction.  The headings of the various sections and subsections
of this Amendment have been inserted for convenience only and shall not in any
way affect the meaning or construction of any of the provisions hereof.

     8.      Counterparts; Effectiveness.  This Amendment may be executed in
any number of counterparts and by different parties hereto on separate
counterparts, each of which when so executed and delivered shall be an original,
but all of which shall together constitute one and the same instrument. This
Amendment shall become effective on the date (the "Amendment

                                       2
<PAGE>   3
Effective Date'') upon which the Administrative Agent shall have received an
executed counterpart hereof from each of the Borrower and the Required Lenders.

IN WITNESS WHEREOF, the parties thereto have caused this Amendment to be
executed by their duly authorized officers as of the date first above written.

         THIS AMENDMENT AGREEMENT (this "Amendment Agreement") is made and
entered into as of this 12th day of April, 1999, by and among THE WACKENHUT

Borrower guarantee payment of all Obligations of the Borrower arising under the
Agreement; and

         WHEREAS, the Borrower has requested that the Agreement be further
amended in the manner described herein and the Agent and the Required Lenders
have agreed, subject to the terms and conditions hereof, to make such amendment,
as provided herein;

         NOW, THEREFORE, the Borrower, the Agent and the Lenders do hereby agree
as follows:

         1. DEFINITIONS. The term "Agreement" as used herein and in the Loan
Documents (as defined in the Agreement) shall mean the Agreement as hereinafter
amended and modified. Unless the context otherwise requires, all terms used
herein without definition shall have the definition provided therefor in the
Agreement.

         2. AMENDMENT. Subject to the conditions set forth herein, the Agreement
is hereby amended, effective as of the date hereof, as follows:

                  (a) The definition of "Consolidated Net Worth" is hereby
         amended by deleting the final clause thereof, reading "PLUS or MINUS,
         as the case may be (iv) the cumulative effect of foreign exchange
         valuations" and inserting in lieu thereof the following:

                  "PLUS (iv) up to $7,000,000 for the cumulative effect of the
                  change in accounting principles regarding start-up costs of
                  WCC."

         amended it shall read as follows:

                           "7.06 CONSOLIDATED NET WORTH. The Borrower will at

                  fiscal quarter of the Borrower, the sum of (A) the amount of

<PAGE>   2

                  Consolidated Net Worth required to be maintained pursuant to
                  this SECTION 7.06 as at the end of the immediately preceding
                  fiscal quarter, plus, (B) 50% of Consolidated Net Income (with
                  no reduction for net losses for any period) for the fiscal
                  quarter of the Borrower ending on such day, provided that for
                  the quarter ended December 31, 1998 there shall be added to
                  Consolidated Net Income up to $7,000,000 for the cumulative
                  effect of the change in accounting principles regarding
                  start-up costs of WCC, plus (C) 75% of the net proceeds to the
                  Borrower from the sale of shares of the Borrower's capital
                  stock received during the fiscal quarter of the Borrower
                  ending on such date. The calculation of this covenant shall be
                  based upon the consolidated financial statements of the
                  Borrower and its Subsidiaries, including WCC."

Agreement for the purpose of (i) agreeing to the amendment to the Agreement and

         condition, financial or otherwise, of the Borrower and its Subsidiaries
         since the date of the most recent financial reports of the Borrower
         received by each Lender under Section 7.17 thereof, other than changes
         in the ordinary course of business, none of which has been a material
         adverse change;

                  (c) The business and properties of the Borrower and its
         Subsidiaries are not and have not been adversely affected in any
         substantial way as the result of any fire, explosion, earthquake,
         accident, strike, lockout, combination of workers, flood, embargo,
         riot, activities of armed forces, war or acts of God or the public
         enemy, or cancellation or loss of any major contracts; and

                  (d) No event has occurred and no condition exists which, upon
         the consummation of the transaction contemplated hereby, constitutes a
         Default or an Event of Default on the part of the Borrower under the
         Agreement, the Notes or any other Loan Document either immediately or
         with the lapse of time or the giving of notice, or both.

         5. CONDITIONS. This Amendment Agreement shall become effective upon the
Borrower delivering to the Agent five (5) counterparts of this Amendment
Agreement duly executed by the Borrower, the Agent and the Required Lenders and
consented to by each of the Subsidiaries and receipt by the Agent of all fees
and expenses due in connection with this Amendment Agreement.

         6. ENTIRE AGREEMENT. This Amendment Agreement sets forth the entire
understanding and agreement of the parties hereto in relation to the subject
matter hereof and supersedes any prior negotiations and agreements among the
parties relative to such subject matter. No promise, conditions, representation
or warranty, express or implied, not herein set forth shall bind any party
hereto, and no one of them has relied on any such promise, condition,
representation or warranty. Each of the parties hereto acknowledges that, except
as in this Amendment Agreement otherwise expressly stated, no representations,
warranties or commitments, express or implied, have been made by any other party
to the other. None of the terms or conditions of this Amendment Agreement may be
changed, modified, waived or canceled orally or otherwise, except by writing, in
the manner provided in the Agreement, specifying such change, modification,
waiver or cancellation of such terms or conditions, or of any proceeding or
succeeding breach thereof.
