$_____________________                                     Nashville, Tennessee
                                                                 May ____, 2002

         FOR VALUE RECEIVED, the undersigned, AMERICAN HEALTHWAYS, INC., a
Delaware corporation (the "BORROWER"), hereby promises to pay to
__________________________ (the "LENDER") or its registered assigns, at the
office of _______________________ ("___________________") at ________________ ,
on the Commitment Termination Date (as defined in the Revolving Credit
Agreement dated as of May ________, 2002, (as the same may be amended,
supplemented or otherwise modified from time to time, the "CREDIT AGREEMENT"),
among the Borrower, the lenders from time to time party thereto and SunTrust
Bank, as administrative agent for the lenders, the lesser of (i) the principal
sum of _____________________________ and 00/100 ($___________) or (ii) the
aggregate unpaid principal amount of all Revolving Loans made by the Lender to
the Borrower pursuant to the Credit Agreement, in lawful money of the United
States of America in immediately available funds, and to pay interest from the
date hereof on the principal amount thereof from time to time outstanding, in
like funds, at said office, at the rate or rates per annum and payable on such
dates as provided in the Credit Agreement. In addition, should legal action or
an attorney-at-law be utilized to collect any amount due hereunder, the
Borrower further promises to pay all costs of collection, including the
reasonable attorneys' fees of the Lender.

         The Borrower promises to pay interest, on demand, on any overdue
principal and, to the extent permitted by law, overdue interest from their due
dates at a rate or rates provided in the Credit Agreement.

         In no event (i) shall Advances be made hereunder in excess of the
Borrowing Base, nor (ii) shall amounts outstanding hereunder be permitted to
exceed the Borrowing Base.

         All borrowings evidenced by this Revolving Credit Note and all
payments and prepayments of the principal hereof and the date thereof shall be
endorsed by the holder hereof on the schedule attached hereto and made a part
hereof or on a continuation thereof which shall be attached hereto and made a
part hereof, or otherwise recorded by such holder in its internal records;
provided that the failure of the holder hereof to make such a notation or any
error in such notation shall not affect the obligations of the Borrower to make
the payments of principal and interest in accordance with the terms of this
Revolving Credit Note and the Credit Agreement.

         Anything in this Note or in any of the other Loan Documents to the
contrary notwithstanding, in no event whatsoever, whether by reason of
advancement of proceeds hereunder, acceleration of the maturity of the unpaid
balance hereunder or otherwise, shall the

<PAGE>

interest and loan charges agreed to be paid to any Lender for the use of the
money advanced or to be advanced hereunder exceed the maximum amounts
collectible under applicable laws in effect from time to time. It is understood
and agreed by the parties that, if for any reason whatsoever the interest or
loan charges paid or contracted to be paid by Borrower in respect of this Note
shall exceed the maximum amounts collectible under applicable laws in effect
from time to time, then ipso facto, the obligation to pay such interest and/or
loan charges shall be reduced to the maximum amounts collectible under
applicable laws in effect from time to time, and any amounts collected by the
Lender that exceed such maximum amounts shall be applied to the reduction of
the principal balance hereunder and/or refunded to Borrower so that at no time
shall the interest or loan charges paid or payable in respect of the
indebtedness evidenced herein exceed the maximum amounts permitted from time to
time by applicable law.

         This Revolving Credit Note is issued in connection with, and is
entitled to the benefits of, the Credit Agreement which, among other things,
contains provisions for the acceleration of the maturity hereof upon the
happening of certain events, for prepayment of the principal hereof prior to
the maturity hereof and for the amendment or waiver of certain provisions of
the Credit Agreement, all upon the terms and conditions therein specified. THIS
REVOLVING CREDIT NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE
LAWS OF THE STATE OF TENNESSEE AND ANY APPLICABLE LAWS OF THE UNITED STATES OF
AMERICA.

                                                                      EXHIBIT C

                                   [FORM OF]

                        SUBSIDIARY GUARANTEE AGREEMENT

         SUBSIDIARY GUARANTEE AGREEMENT dated as of May 31, 2002 , among each
of the Subsidiaries listed on Schedule I hereto (each such subsidiary
individually, a "Guarantor" and collectively, the "Guarantors") of AMERICAN
HEALTHWAYS, INC., a Delaware corporation (the "Borrower"), and SUNTRUST BANK, a
Georgia banking corporation as administrative agent (the "Administrative
Agent") for the Lenders (as defined in the Credit Agreement referred to below).

         Reference is made to the Revolving Credit Agreement dated as of May
31, 2002 (as amended, supplemented or otherwise modified from time to time, the
"Credit Agreement"), among the Borrower, the lenders from time to time party
thereto (the "Lenders") and SunTrust Bank, as administrative agent for the
Lenders (in such capacity, the "Administrative Agent"), and issuing bank (in
such capacity, the "Issuing Bank"). Capitalized terms used herein and not
defined herein shall have the meanings assigned to such terms in the Credit
Agreement.

         The Lenders have agreed to make Loans to the Borrower, and the Issuing
Bank has agreed to issue Letters of Credit for the account of the Borrower,
pursuant to, and upon the terms and subject to the conditions specified in, the
Credit Agreement. Each of the Guarantors is a direct or indirect wholly-owned
Subsidiary of the Borrower and acknowledges that it will derive substantial
benefit from the making of the Loans by the Lenders, and the issuance of the
Letters of Credit by the Issuing Bank. The obligations of the Lenders to make
Loans and of the Issuing Bank to issue Letters of Credit are conditioned on,
among other things, the execution and delivery by the Guarantors of a
Subsidiary Guarantee Agreement in the form hereof. As consideration therefor
and in order to induce the Lenders to make Loans and the Issuing Bank to issue
Letters of Credit, the Guarantors are willing to execute this Subsidiary
Guarantee Agreement.

         Accordingly, the parties hereto agree as follows:

         SECTION 1.        Guarantee. Each Guarantor unconditionally
guarantees, jointly with the other Guarantors and severally, as a primary
obligor and not merely as a surety, (a) the due and punctual payment of (i) the
principal of and premium, if any, and interest (including interest accruing
during the pendency of any bankruptcy, insolvency, receivership or other
similar proceeding, regardless of whether allowed or allowable in such
proceeding) on the Loans, when and as due, whether at maturity, by
acceleration, upon one or more dates set for prepayment or otherwise, (ii) each
payment required to be made by the Borrower under the Credit Agreement in
respect of any Letter of Credit, when and as due, including payments in respect
of reimbursement or disbursements, interest thereon and obligations to provide
cash collateral, and (iii) all other monetary obligations, including fees,
costs, expenses and indemnities, whether

<PAGE>

primary, secondary, direct, contingent, fixed or otherwise (including monetary
obligations incurred during the pendency of any bankruptcy, insolvency,
receivership or other similar proceeding, regardless of whether allowed or
allowable in such proceeding), of the Loan Parties to the Administrative Agent
and the Lenders under the Credit Agreement and the other Loan Documents, (b)
the due and punctual performance of all covenants, agreements, obligations and
liabilities of the Loan Parties under or pursuant to the Credit Agreement and
the other Loan Documents; and (c) the due and punctual payment and performance
of all obligations of the Borrower, monetary or otherwise, under each Hedging
Agreement entered into with a counterparty that was a Lender or an Affiliate of
a Lender at the time such Hedging Agreement was entered into (all the monetary
and other obligations referred to in the preceding clauses (a) through (c)
being collectively called the "Obligations"). Each Guarantor further agrees
that the Obligations may be extended or renewed, in whole or in part, without
notice to or further assent from it, and that it will remain bound upon its
guarantee notwithstanding any extension or renewal of any Obligation.

         SECTION 2.        Obligations Not Waived. To the fullest extent
permitted by applicable law, each Guarantor waives presentment to, demand of
payment from and protest to the Borrower of any of the Obligations, and also
waives notice of acceptance of its guarantee and notice of protest for
nonpayment. To the fullest extent permitted by applicable law, the obligations
of each Guarantor hereunder shall not be affected by (a) the failure of the
Administrative Agent or any Lender to assert any claim or demand or to enforce
or exercise any right or remedy against the Borrower or any other Guarantor
under the provisions of the Credit Agreement, any other Loan Document or
otherwise, (b) any rescission, waiver, amendment or modification of, or any
release from any of the terms or provisions of, this Agreement, any other Loan
Document, any Guarantee or any other agreement, including with respect to any
other Guarantor under this Agreement, or (c) the failure to perfect any
security interest in, or the release of, any of the security held by or on
behalf of the Administrative Agent or any Lender.

         SECTION 3.        Security. Each of the Guarantors authorizes the
Administrative Agent and each of the Lenders to (a) take and hold security for
payment of this Guarantee and the Obligations and exchange, enforce, waive and
release any such security, (b) apply such security and direct the order or
manner of sale thereof as they in their sole discretion may determine and (c)
release or substitute any one or more endorsees, other guarantors of other
obligors.

         SECTION 4.        Guarantee of Payment. Each Guarantor further agrees
that its guarantee constitutes a guarantee of payment when due and not of
collection, and waives any right to require that any resort be had by the
Administrative Agent or any Lender to any of the security held for payment of
the Obligations or to any balance of any deposit account or credit on the books
of the Administrative Agent or any Lender in favor of the Borrower or any other
person.

         SECTION 5.        No Discharge or Diminishment of Guarantee. The
obligations of each Guarantor hereunder shall not be subject to any reduction,
limitation, impairment or termination for any reason (other than the
indefeasible payment in full in cash of the Obligations), including any claim
of waiver, release, surrender, alteration or compromise of any of the
Obligations, and shall not be subject to any defense or setoff, counterclaim,
recoupment or termination whatsoever by reason of the invalidity, illegality or
unenforceability of the Obligations or otherwise. Without limiting the
generality of the foregoing, the obligations of each Guarantor

<PAGE>

hereunder shall not be discharged or impaired or otherwise affected by the
failure of the Administrative Agent or any Lender to assert any claim or demand
or to enforce any remedy under the Credit Agreement, any other Loan Document or
any other agreement, by any waiver or modification of any provision of any
thereof, by any default, failure or delay, willful or otherwise, in the
performance of the Obligations, or by any other act or omission that may or
might in any manner or to the extent vary the risk of any Guarantor or that
would otherwise operate as a discharge of each Guarantor as a matter of law or
equity (other than the indefeasible payment in full in cash of all the
Obligations).

         SECTION 6.        Defenses of Borrower Waived. To the fullest extent
permitted by applicable law, each Guarantor waives any defense based on or
arising out of any defense of the Borrower or the unenforceability of the
Obligations or any part thereof from any cause, or the cessation from any cause
of the liability of the Borrower, other than the final and indefeasible payment
in full in cash of the Obligations. The Administrative Agent and the Lenders
may, at their election, foreclose on any security held by one or more of them
by one or more judicial or nonjudicial sales, accept an assignment of any such
security in lieu of foreclosure, compromise or adjust any part of the
Obligations, make any other accommodation with the Borrower or any other
guarantor, without affecting or impairing in any way the liability of any
Guarantor hereunder except to the extent the Obligations have been fully,
finally and indefeasibly paid in cash. Pursuant to applicable law, each
Guarantor waives any defense arising out of any such election even though such
election operates, pursuant to applicable law, to impair or to extinguish any
right of reimbursement or subrogation or other right or remedy of such
Guarantor against the Borrower or any other Guarantor or guarantor, as the case
may be, or any security.

         SECTION 7.        Agreement to Pay; Subordination. In furtherance of
the foregoing and not in limitation of any other right that the Administrative
Agent or any Lender has at law or in equity against any Guarantor by virtue
hereof, upon the failure of the Borrower or any other Loan Party to pay any
Obligation when and as the same shall become due, whether at maturity, by
acceleration, after notice of prepayment or otherwise, each Guarantor hereby
promises to and will forthwith pay, or cause to be paid, to the Administrative
Agent for the benefit of the Lenders in cash the amount of such unpaid
Obligations. Upon payment by any Guarantor of any sums to the Administrative
Agent, all rights of such Guarantor against the Borrower arising as a result
thereof by way of right of subrogation, contribution, reimbursement, indemnity
or otherwise shall in all respects be subordinate and junior in right of
payment to the prior indefeasible payment in full in cash of all the
Obligations. In addition, any indebtedness of the Borrower now or hereafter
held by any Guarantor is hereby subordinated in right of payment to the prior
payment in full in cash of the Obligations. If any amount shall erroneously be
paid to any Guarantor on account of (i) such subrogation, contribution,
reimbursement, indemnity or similar right or (ii) any such indebtedness of the
Borrower, such amount shall be held in trust for the benefit of the
Administrative Agent and the Lenders and shall forthwith be paid to the
Administrative Agent to be credited against the payment of the Obligations,
whether matured or unmatured, in accordance with the terms of the Loan
Documents.

         SECTION 8.        Information. Each Guarantor assumes all
responsibility for being and keeping itself informed of the Borrower's
financial condition and assets, and of all other circumstances bearing upon the
risk of nonpayment of the Obligations and the nature, scope and extent of the
risks that such Guarantor assumes and incurs hereunder, and agrees that none of
the

<PAGE>

Administrative Agent or the Lenders will have any duty to advise any of the
Guarantors of information known to it or any of them regarding such
circumstances or risks.

         SECTION 9.        Representations and Warranties. Each Guarantor
represents and warrants as to itself that all representations and warranties
relating to it (as a Subsidiary of the Borrower) contained in the Credit
Agreement are true and correct as of the date made.

         SECTION 10.       Termination. The guarantees made hereunder (a) shall
terminate when all the Obligations have been paid in full in cash and the
Lenders have no further commitment to lend under the Credit Agreement, the LC
Exposure has been reduced to zero and the Issuing Bank has no further
obligation to issue Letters of Credit under the Credit Agreement and (b) shall
continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any Obligation is rescinded or must otherwise
be restored by any Lender or any Guarantor upon the bankruptcy or
reorganization of the Borrower, any Guarantor or otherwise. In connection with
the foregoing, the Administrative Agent shall execute and deliver to such
Guarantor or Guarantor's designee, at such Guarantor's expense, any documents
or instruments which such Guarantor shall reasonably request from time to time
to evidence such termination and release.

         SECTION 11.       Binding Effect; Several Agreement; Assignments.
Whenever in this Agreement any of the parties hereto is referred to, such
reference shall be deemed to include the successors and assigns of such party;
and all covenants, promises and agreements by or on behalf of the Guarantors
that are contained in this Agreement shall bind and inure to the benefit of
each party hereto and their respective successors and assigns. This Agreement
shall become effective as to any Guarantor when a counterpart hereof executed
on behalf of such Guarantor shall have been delivered to the Administrative
Agent, and a counterpart hereof shall have been executed on behalf of the
Administrative Agent, and thereafter shall be binding upon such Guarantor and
the Administrative Agent and their respective successors and assigns, and shall
inure to the benefit of such Guarantor, the Administrative Agent and the
Lenders, and their respective successors and assigns, except that no Guarantor
shall have the right to assign its rights or obligations hereunder or any
interest herein (and any such attempted assignment shall be void). If all of
the capital stock of a Guarantor is sold, transferred or otherwise disposed of
pursuant to a transaction permitted by the Credit Agreement, such Guarantor
shall be released from its obligations under this Agreement without further
action. This Agreement shall be construed as a separate agreement with respect
to each Guarantor and may be amended, modified, supplemented, waived or
released with respect to any Guarantor without the approval of any other
Guarantor and without affecting the obligations of any other Guarantor
hereunder.

         SECTION 12.       Waivers; Amendment. (a) No failure or delay of the
Administrative Agent in exercising any power or right hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise of any such right
or power, or any abandonment or discontinuance of steps to enforce such a right
or power, preclude any other or further exercise thereof or the exercise of any
other right or power. The rights and of the Administrative Agent hereunder and
of the Lenders under the other Loan Documents are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver
of any provision of this Agreement or consent to any departure by any Guarantor
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) below, and then such waiver and consent shall be

<PAGE>

effective only in the specific instance and for the purpose for which given. No
notice or demand on any Guarantor in any case shall entitle such Guarantor to
any other or further notice in similar or other circumstances.

         (b)      Neither this Agreement nor any provision hereof may be
waived, amended or modified except pursuant to a written agreement entered into
between the Guarantors with respect to which such waiver, amendment or
modification relates and the Administrative Agent, with the prior written
consent of the Required Lenders (except as otherwise provided in the Credit
Agreement).

         SECTION 13.       Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY,
AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TENNESSEE.

         SECTION 14.       Notices. All communications and notices hereunder
shall be in writing and given as provided in Section 10.01 of the Credit
Agreement. All communications and notices hereunder to each Guarantor shall be
given to it at its address set forth on Schedule I attached hereto.

         SECTION 15.       Survival of Agreement; Severability. (a) All
covenants, agreements representations and warranties made by the Guarantors
herein and in the certificates or other instruments prepared or delivered in
connection with or pursuant to this Agreement or the other Loan Document shall
be considered to have been relied upon by the Administrative Agent and the
Lenders and shall survive the making by the Lenders of the Loans and the
issuance of the Letters of Credit by the Issuing Bank regardless of any
investigation made by any of them or on their behalf, and shall continue in
full force and effect as long as the principal of or any accrued interest on
any Loan or any other fee or amount payable under this Agreement or any other
Loan Document is outstanding and unpaid or the LC Exposure does not equal zero
and as long as the Commitments have not been terminated.

         (b)      In the event one or more of the provisions contained in this
Agreement or in any other Loan Document should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein and therein shall not in any way be
affected or impaired thereby (it being understood that the invalidity of a
particular provision in a particular jurisdiction shall not in and of itself
affect the validity of such provision in any other jurisdiction). The parties
shall endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

         SECTION 16.       Counterparts. This Agreement may be executed in
counterparts, each of which shall constitute an original, but all of which when
taken together shall constitute a single contract (subject to Section 11), and
shall become effective as provided in Section 11. Delivery of an executed
signature page to this Agreement by facsimile transmission shall be as
effective as delivery of a manually executed counterpart of this Agreement.

         SECTION 17.       Rules of Interpretation. The rules of interpretation
specified in Section 1.03 of the Credit Agreement shall be applicable to this
Agreement.

<PAGE>

         SECTION 18.       Jurisdiction; Consent to Service of Process. (a)
Each Guarantor hereby irrevocably and unconditionally submits, for itself and
its property, to the nonexclusive jurisdiction of any Tennessee State court or
Federal court of the United States of America sitting in Nashville, Tennessee,
and any appellate court from any thereof, in any action or proceeding arising
out of or relating to this Agreement or the other Loan Documents, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such Tennessee State
court or, to the extent permitted by law, in such Federal court. Each of the
parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement
shall affect any right that the Administrative Agent, the Issuing Bank or any
Lender may otherwise have to bring any action or proceeding relating to this
Agreement or the other Loan Documents against any Guarantor or its properties
in the courts of any jurisdiction.

         (b)      Each Guarantor hereby irrevocably and unconditionally waives,
to the fullest extent it may legally and effectively do so, any objection that
it may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement or the other Loan
Documents in any Tennessee State or Federal court. Each of the parties hereto
hereby irrevocably waives, to the fullest extent permitted by law, the defense
of an inconvenient forum to the maintenance of such action or proceeding in any
such court.

         (c)      Each party to this Agreement irrevocably consents to service
of process in the manner provided for notices in Section 14. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

         SECTION 19.       Waiver of Jury Trial. EACH PARTY HERETO HEREBY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY
HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY
ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE OTHER LOAN
DOCUMENTS. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR
ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH
OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE
BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS
APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN
THIS SECTION 19.

         SECTION 20.       Additional Guarantors. Pursuant to Section 5.12 of
the Credit Agreement, each Subsidiary Loan Party that was not in existence on
the date of the Credit Agreement is required to enter into this Agreement as a
Guarantor upon becoming Subsidiary Loan Party. Upon execution and delivery
after the date hereof by the Administrative Agent and such Subsidiary of an
instrument in the form of Annex 1, such Subsidiary shall become a Guarantor
hereunder with the same force and effect as if originally named as a Guarantor
herein. The execution and delivery of any instrument adding an additional
Guarantor as a party to this Agreement shall not require the consent of any
other Guarantor hereunder. The rights and

<PAGE>

obligations of each Guarantor hereunder shall remain in full force and effect
notwithstanding the addition of any new Guarantor as a party to this Agreement.

         SECTION 21.       Right of Setoff. If an Event of Default shall have
occurred and be continuing, each Lender and the Issuing Bank are hereby
authorized at any time and from time to time, to the fullest extent permitted
by law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other Indebtedness at any
time owing by such Lender or the Issuing Bank to or for the credit or the
account of any Guarantor against any or all the obligations of such Guarantor
now or hereafter existing under this Agreement and the other Loan Documents
held by such Lender or the Issuing Bank, irrespective of whether or not such
Person shall have made any demand under this Agreement or any other Loan
Document and although such obligations may be unmatured. The rights of each
Lender and the Issuing Bank under this Section 21 are in addition to other
rights and remedies (including other rights of setoff) which such Lender or the
Issuing Bank, as the case may be, may have.

         IN WITNESS WHEREOF, the parties hereto have duly executed this
Agreement as of the day and year first above written.

                                 ANNEX 1 TO THE
                         SUBSIDIARY GUARANTEE AGREEMENT

         SUPPLEMENT NO. [ ] dated as of [        ], to the Subsidiary Guarantee
Agreement (the "Guarantee Agreement") dated as of [         ] among each of the
subsidiaries listed on Schedule I thereto (each such Subsidiary individually, a
"Guarantor" and collectively, the "Guarantors") of AMERICAN HEALTHWAYS, INC., a
Delaware corporation (the "Borrower"), and SUNTRUST BANK, a Georgia banking
corporation, as Administrative Agent (the "Administrative Agent") for the
Lenders (as defined in the Credit Agreement referred to below).

         A.       Reference is made to the Revolving Credit Agreement dated as
of May 31, 2002 (as amended, supplemented or otherwise modified from time to
time, the "Credit Agreement"), among the Borrower, the lenders from time to
time party thereto (the "Lenders") and SunTrust Bank, as Administrative Agent,
and issuing bank (in such capacity, the "Issuing Bank"). Capitalized terms used
herein and not otherwise defined herein shall have the meanings assigned to
such terms in the Credit Agreement.

         B.       Capitalized terms used herein and not otherwise defined
herein shall have the meanings assigned to such terms in the Guarantee
Agreement and the Credit Agreement.

         C.       The Guarantors have entered into the Guarantee Agreement in
order to induce the Lenders to make Loans and the Issuing Bank to issue Letters
of Credit. Pursuant to Section 5.12 of the Credit Agreement, each Subsidiary
Loan Party that was not in existence or not a Subsidiary Loan Party on the date
of the Credit Agreement is required to enter into the Guarantee Agreement as a
Guarantor upon becoming a Subsidiary Loan Party. Section 20 of the Guarantee
Agreement provides that additional Subsidiaries of the Borrower may become
Guarantors under the Guarantee Agreement by execution and delivery of an
instrument in the form of this Supplement. The undersigned Subsidiary of the
Borrower (the "New Guarantor") is executing this Supplement in accordance with
the requirements of the Credit Agreement to become a Guarantor under the
Guarantee Agreement in order to induce the Lenders to make additional Loans and
the Issuing Bank to issue additional Letters of Credit and as consideration for
Loans previously made and Letters of Credit previously issued.

         Accordingly, the Administrative Agent and the New Guarantor agree as
follows:

         SECTION 1.        In accordance with Section 20 of the Guarantee
Agreement, the New Guarantor by its signature below becomes a Guarantor under
the Guarantee Agreement with the same force and effect as if originally named
therein as a Guarantor and the New Guarantor hereby (a) agrees to all the terms
and provisions of the Guarantee Agreement applicable to it as Guarantor
thereunder and (b) represents and warrants that the representations and
warranties made by it as a Guarantor thereunder are true and correct on and as
of the date hereof. Each reference to a Guarantor in the Guarantee Agreement
shall be deemed to include the New Guarantor. The Guarantee Agreement is hereby
incorporated herein by reference.

<PAGE>

         SECTION 2.        The New Guarantor represents and warrants to the
Administrative Agent and the Lenders that this Supplement has been duly
authorized, executed and delivered by it and constitutes its legal, valid and
binding obligation, enforceable against it in accordance with its terms.

         SECTION 3.        This Supplement may be executed in counterparts
each of which shall constitute an original, but all of which when taken
together shall constitute a single contract. This Supplement shall become
effective when the Administrative Agent shall have received counterparts of
this Supplement that, when taken together, bear the signatures of the New
Guarantor and the Administrative Agent. Delivery of an executed signature page
to this Supplement by facsimile transmission shall be as effective as delivery
of a manually signed counterpart of this Supplement.

         SECTION 4.        Except as expressly supplemented hereby, the
Guarantee Agreement shall remain in full force and effect.

         SECTION 5.        THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TENNESSEE.

         SECTION 6.        In case any one or more of the provisions contained
in this Supplement should be held invalid, illegal or unenforceable in any
respect, the validity, legality and enforceability of the remaining provisions
contained herein and in the Guarantee Agreement shall not in any way be
affected or impaired thereby (it being understood that the invalidity of a
particular provision hereof in a particular jurisdiction shall not in and of
itself affect the validity of such provision in any other jurisdiction). The
parties hereto shall endeavor in good-faith negotiations to replace the
invalid, illegal or unenforceable provisions with valid provisions the economic
effect of which comes as close as possible to that of the invalid, illegal or
unenforceable provisions.

         SECTION 7.        All communications and notices hereunder shall be in
writing and given as provided in Section 14 of the Guarantee Agreement. All
communications and notices hereunder to the New Guarantor shall be given to it
at the address set forth under its signature below, with a copy to the
Borrower.

         SECTION 8.        The New Guarantor agrees to reimburse the
Administrative Agent for its out-of-pocket expenses in connection with this
Supplement, including the fees, disbursements and other charges of counsel for
the Administrative Agent.

         IN WITNESS WHEREOF, the New Guarantor and the Administrative Agent
have duly executed this Supplement to the Guarantee Agreement as of the day and
year first above written.

                                    [Name of New Guarantor]
