                  2A.1 L/C Commitment. (a) Subject to the terms and conditions
         hereof, the Issuing Bank, in reliance on the agreements of the other
         Banks set forth in subsection 2A.4(a), agrees to issue letters of
         credit (such letters of credit, "Letters of Credit") for the account of
         the Company on any Business Day during the Commitment Period in such
         form as may be approved from time to time by the Issuing Bank; provided
         that the Issuing Bank shall have no obligation to issue any Letter of

         Obligations would exceed the L/C Commitment or (2) the aggregate amount
         of the Available Commitments would be less than zero.

                  (b) Each Letter of Credit shall expire no later than the
         earlier of (x) the first anniversary of its date of issuance (it being
         agreed that a provision in a Letter of Credit for automatic renewal of
         such Letter of Credit for a period of no more than one year at a time
         in the absence of a termination notice shall not be deemed to be an
         expiry date of later than the date such termination notice would be

                                                                               4



         one-year term may provide for the renewal thereof for additional
         one-year periods (which shall in no event extend beyond the date
         referred to in clause (y) above).

                  (c) The Issuing Bank shall not at any time be obligated to
         issue any Letter of Credit hereunder if such issuance would conflict

         limits imposed by, any applicable Requirement of Law.

                  2A.2 Procedure for Issuance of Letters of Credit. The Company
         may from time to time request that the Issuing Bank issue a Letter of
         Credit by delivering to the Issuing Bank at its address for notices
         specified herein an Application therefor, completed to the satisfaction
         of the Issuing Bank, and such other certificates, documents and other
         papers and information as the Issuing Bank may request. Upon receipt of
         any Application, the Issuing Bank will process such Application and the
         certificates, documents and other papers and information delivered to
         it in connection therewith in accordance with its customary procedures
         and shall promptly issue the Letter of Credit requested thereby (but in
         no event shall the Issuing Bank be required to issue any Letter of
         Credit earlier than three Business Days after its receipt of the
         Application therefor and all such other certificates, documents and
         other papers and information relating thereto) by issuing the original
         of such Letter of Credit to the beneficiary thereof or as otherwise may
         be agreed by the Issuing Bank and the Company. The Issuing Bank shall
         furnish a copy of such Letter of Credit to the Company promptly
         following the issuance thereof.

                  2A.3 Fees and Other Charges. (a) The Company will pay a fee on
         all outstanding Letters of Credit at a per annum rate equal to the
         Applicable Margin then in effect with respect to Eurodollar Loans,
         shared ratably among the Banks and payable quarterly in arrears on each
         L/C Fee Payment Date after the date of issuance of each Letter of
         Credit. In addition, the Company shall pay to the Agent, for the
         account of the Issuing Bank, a fronting fee with respect to each Letter
         of Credit in an amount equal to 0.125% of the face amount of such
         Letter of Credit. Such fronting fee shall be payable quarterly in
         arrears and shall be nonrefundable.

                  (b) In addition to the foregoing fees, the Company shall pay
         or reimburse the Issuing Bank for such normal and customary costs and
         expenses as are incurred or charged by the Issuing Bank in issuing,
         effecting payment under, amending or otherwise administering any Letter
         of Credit.

                  (c) The Agent shall, promptly following its receipt thereof,
         distribute to the Issuing Bank and the L/C Participants all fees
         received by the Agent for their respective accounts pursuant to this
         subsection.

                  2A.4 L/C Participations. (a) The Issuing Bank irrevocably
         agrees to grant and hereby grants to each L/C Participant, and, to
         induce the Issuing Bank to issue Letters of Credit hereunder, each L/C
         Participant irrevocably agrees to accept and purchase and hereby
         accepts and purchases from the Issuing Bank, on the terms and
         conditions hereinafter stated, for such L/C Participant's own account
         and risk an undivided interest

                                                                     


   5
                                                                               5




         equal to such L/C Participant's Commitment Percentage in the Issuing
         Bank's obligations and rights under each Letter of Credit issued
         hereunder and the amount of each draft paid by the Issuing Bank
         thereunder. Each L/C Participant unconditionally and irrevocably agrees
         with the Issuing Bank that, if a draft is paid under any Letter of
         Credit for which the Issuing Bank is not reimbursed in full by the
         Company in accordance with the terms of this Agreement, such L/C
         Participant shall pay to the Issuing Bank upon demand at the Issuing
         Bank's address specified herein an amount equal to such L/C
         Participant's Commitment Percentage of the amount of such draft, or any
         part thereof, which is not so reimbursed.

                  (b) If any amount required to be paid by any L/C Participant
         to the Issuing Bank pursuant to paragraph 2A.4(a) in respect of any
         unreimbursed portion of any payment made by the Issuing Bank under any
         Letter of Credit is paid to the Issuing Bank within three Business Days
         after the date such payment is due, such L/C Participant shall pay to
         the Issuing Bank on demand an amount equal to the product of (1) such
         amount, times (2) the daily average Federal funds rate, as quoted by
         the Issuing Bank, during the period from and including the date such
         payment is required to the date on which such payment is immediately
         available to the Issuing Bank, times (3) a fraction the numerator of
         which is the number of days that elapse during such period and the
         denominator of which is 360. If any such amount required to be paid by
         any L/C Participant pursuant to paragraph 2A.4(a) is not in fact made
         available to the Issuing Bank by such L/C Participant within three
         Business Days after the date such payment is due, the Issuing Bank
         shall be entitled to recover from such L/C Participant, on demand, such
         amount with interest thereon calculated from such due date at the rate
         per annum applicable to Alternate Base Rate Loans hereunder. A
         certificate of the Issuing Bank submitted to any L/C Participant with
         respect to any amounts owing under this subsection shall be conclusive
         in the absence of manifest error.

                  (c) Whenever, at any time after the Issuing Bank has made
         payment under any Letter of Credit and has received from any L/C
         Participant its pro rata share of such payment in accordance with
         subsection 2A.4(a), the Issuing Bank receives any payment related to
         such Letter of Credit (whether directly from the Company or otherwise,
         including proceeds of collateral applied thereto by the Issuing Bank),
         or any payment of interest on account thereof, the Issuing Bank will
         distribute to such L/C Participant its pro rata share thereof;
         provided, however, that in the event that any such payment received by
         the Issuing Bank shall be required to be returned by the Issuing Bank,
         such L/C Participant shall return to the Issuing Bank the portion
         thereof previously distributed by the Issuing Bank to it.

                  2A.5 Reimbursement Obligation of the Company. (a) The Company
         agrees to reimburse the Issuing Bank on each date on which the Issuing
         Bank notifies the Company of the date and amount of a draft presented
         under any Letter of Credit and paid by the Issuing Bank for the amount
         of (1) such draft so paid and (2) any taxes, fees, charges or other
         costs or expenses incurred by the Issuing Bank in connection with such
         payment. Each such payment shall be made to the Issuing Bank at its
         address for notices specified

         herein in lawful money of the United States of America and in
         immediately available funds.

                  (b) Interest shall be payable on any and all amounts remaining
         unpaid by the Company under this subsection from the date such amounts
         become payable (whether at stated maturity, by acceleration or
         otherwise) until payment in full at the rate set forth in (i) until the
         second Business Day following the date of the applicable drawing,
         subsection 2.7(b) and (ii) thereafter, subsection 2.7(c).

                  2A.6 Obligations Absolute. (a) The Company's obligations under
         this Section 2A shall be absolute and unconditional under any and all
         circumstances and irrespective of any set-off, counterclaim or defense
         to payment which the Company may have or have had against the Issuing
         Bank or any beneficiary of a Letter of Credit.

                  (b) The Company also agrees with the Issuing Bank that the
         Issuing Bank shall not be responsible for, and the Company's
         Reimbursement Obligations under subsection 2A.5(a) shall not be
         affected by, among other things, (1) the validity or genuineness of
         documents or of any endorsements thereon, even though such documents
         shall in fact prove to be invalid, fraudulent or forged, or (2) any
         dispute between or among the Company and any beneficiary of any Letter
         of Credit or any other party to which such Letter of Credit may be
         transferred or (3) any claims whatsoever of the Company against any
         beneficiary of such Letter of Credit or any such transferee.

                  (c) The Issuing Bank shall not be liable for any error,
         omission, interruption or delay in transmission, dispatch or delivery
         of any message or advice, however transmitted, in connection with any
         Letter of Credit, except for errors or omissions caused by the Issuing
         Bank's gross negligence or willful misconduct.

                  (d) The Company agrees that any action taken or omitted by the
         Issuing Bank under or in connection with any Letter of Credit or the
         related drafts or documents, if done in the absence of gross negligence
         of willful misconduct and in accordance with the standards of care
         specified in the Uniform Commercial Code of the State of New York,
         shall be binding on the Company and shall not result in any liability
         of the Issuing Bank to the Company.

                  2A.7 Letter of Credit Payments. If any draft shall be
         presented for payment under any Letter of Credit, the Issuing Bank
         shall promptly notify the Company of the date and amount thereof. The
         responsibility of the Issuing Bank to the Company in connection with
         any draft presented for payment under any Letter of Credit shall, in
         addition to any payment obligation expressly provided for in such
         Letter of Credit, be limited to determining that the documents
         (including each draft) delivered under such Letter of Credit in
         connection with such presentment are in conformity with such Letter of
         Credit.

                  2A.8 Application. To the extent that any provision of any
         Application related to any Letter of Credit is inconsistent with the
         provisions of this Section 2A, the provisions of this Section 2A shall
         apply.`".

         deleting subsection 3.12 in its entirety and substituting in lieu
         thereof the following:

                  `3.12. Pension Plans. Each Plan maintained by the Company, any
                  Subsidiary or any Control Group Person or to which any of them
                  makes or will make contributions is in material compliance
                  with the applicable provisions of ERISA and the Code. Neither
                  the Company, any Subsidiary, nor any Control Group Person has
                  since August 31, 1986 maintained, contributed to or

                  a complete withdrawal would result in any withdrawal

                  the funding standards applicable to all Plans that are not
                  Multiemployer Plans, and there exists no event or condition
                  which would permit the institution of proceedings to terminate
                  any Plan that is not a Multiemployer Plan. The current value
                  of the benefits guaranteed under Title IV of ERISA of each
                  Plan that is not a Multiemployer Plan does not exceed the
                  current value of such Plan's assets allocable to such
                  benefits.`"

                  the case may be, at the time of acquisition of such property
                  or capital stock, as the case maybe, by the Company or a

unless any Loans made and/or to be made to and all other sums payable by the
Company under this Agreement shall be secured equally and ratably with (or prior
to) such Indebtedness so long as such Indebtedness shall be so secured.

without securing the Loans made and/or to be made to and all other sums payable
by the Company under this Agreement, create, issue or assume Indebtedness which

Subsidiaries) in connection with the tax-free spin-off distributions of the
common stock of Life Point and Triad to the shareholders of the Company),
including Indebtedness in respect of Sale-and-Lease-back Transactions (other
than those permitted by subsection 5.13(b)), does not exceed 10% of Consolidated
Net Tangible Assets of the Company and its Subsidiaries (calculated after giving
pro forma effect thereto as if the tax-free spin-off distributions of the common
stock of LifePoint and Triad to the shareholders of the Company occurred on the
first day of the testing period thereof).`".
