              SECOND AMENDED AND RESTATED BORROWER PLEDGE AGREEMENT

         This SECOND AMENDED AND RESTATED BORROWER PLEDGE AGREEMENT (as amended,
amended and restated or otherwise modified from time to time, this "AGREEMENT")
is dated as of July __, 2003 and entered into by and between AMERICAN
HOMEPATIENT, INC., a Delaware corporation ("PLEDGOR"), and BANK OF MONTREAL, as
agent for and representative of (in such capacity herein called "SECURED PARTY")
the financial institutions ("BANKS") that hold a promissory note payable to such
Banks as set forth on Exhibit A attached hereto (the "Promissory Note") and
replaces the Amended and Restated Borrower Pledge Agreement dated as of December
28, 1995 between Pledgor and Bankers Trust Company as the predecessor to the
Secured Party (the "Prior Pledge Agreement").

         The foregoing pledge and grant of security interest confirms the pledge
and grant of a first priority security interest in the Pledged Collateral to

362(a) of the Bankruptcy Code, 11 U.S.C. Section 362(a)), of all obligations and
liabilities of every nature of Pledgor now or hereafter existing under or
arising out of or in connection with the Promissory Note, and including all or
any portion of such obligations or liabilities that are paid, to the extent all
or any part of such payment is avoided or recovered directly or indirectly from
Secured Party or any Bank as a preference, fraudulent transfer or otherwise (all
such obligations and liabilities being the "UNDERLYING DEBT"), and all
obligations of every nature of Pledgor now or hereafter existing under this
Agreement (all such obligations of Pledgor, together with the Underlying Debt,
being the "SECURED OBLIGATIONS").

instruments representing or evidencing the Pledged Collateral shall be delivered

transfer or assignment in blank, all in form and substance satisfactory to
Secured Party. . In addition, Secured Party shall have the right at any time to
exchange certificates or instruments representing or evidencing Pledged
Collateral for certificates or instruments of smaller or larger denominations.

         SECTION 4. REPRESENTATIONS AND WARRANTIES. Pledgor represents and
warrants as follows:

         (a)      Due Authorization. etc. of Pledged Collateral. All of the
Pledged Shares have been duly authorized and validly issued and are fully paid

authenticated or issued, and delivered and is the legal, valid and binding
obligation of the issuers thereof and is not in default.

agreements outstanding with respect to, or property that is now or hereafter
convertible into, or that requires the issuance or sale of, any Pledged Shares.

levies or claims not later than five days prior to the date of any proposed sale
under any judgement, writ or warrant of attachment entered or filed against
Pledgor or any of the Pledged Collateral as a result of the failure to make such
payment.

         SECTION 6. FURTHER ASSURANCES; PLEDGE AMENDMENTS.

         (a)      Pledgor agrees that from time to time, at the expense of
Pledgor, Pledgor will promptly execute and deliver all further instruments and
documents, and take all further action, that reasonably may be necessary or
desirable, or that Secured Party may request in order to perfect and protect any
security interest granted or purported to be granted hereby or to enable Secured
Party to exercise and enforce its rights and remedies hereunder with respect to
any Pledged Collateral. Without limiting the generality of the foregoing,
Pledgor will: (i) execute and file such financing or continuation statements, or
amendments thereto, and such other instruments or notices, as may be necessary
or desirable, or as Secured Party may request, in order to perfect and preserve
the security interests granted or purported to be granted hereby and (ii) at
Secured Party's request, appear in and defend any action or proceeding that may
affect Pledgor's title to or Secured Party's security interest in all or any
part of the Pledged Collateral.

ten Business Days) deliver to Secured Party a Pledge Amendment (a "PLEDGE
AMENDMENT"), in respect of the additional Pledged Shares or Pledged Debt to be
pledged pursuant to this Agreement. Pledgor hereby authorizes Secured Party to
attach each Pledge Amendment to this Agreement and agrees that all Pledged
Shares or Pledged Debt listed on any Pledge Amendment delivered to Secured Party
shall for all purposes hereunder be considered Pledged Collateral; provided that
the failure of Pledgor to execute a Pledge Amendment with respect to any
additional Pledged Shares or Pledged Debt pledged pursuant to this Agreement
shall not impair the security interest of Secured Party therein or otherwise
adversely affect the rights and remedies of Secured Party hereunder with respect
thereto.

         SECTION 7. VOTING RIGHTS; DIVIDENDS.

         (a)      So long as no Event of Default shall have occurred and be
continuing (for the purposes of this Agreement, "Default" or "Event of Default"
shall mean Pledgor's failure to pay when due any amounts under the Promissory
Note):

                  (i)      Pledgor shall be entitled to exercise any and all
         voting and other consensual rights pertaining to the Pledged Collateral
         or any part thereof for any purpose not inconsistent with the terms of
         this Agreement; provided, however, that Pledgor shall not exercise or
         refrain from exercising any such right if Secured Party shall have
         notified Pledgor that, in Secured Party's judgment, such action would
         have a material adverse effect on the value of the Pledged Collateral
         or any part thereof; and provided, further, that Pledgor shall give
         Secured Party at least five Business Days' prior written notice of the
         manner in which it intends to exercise, or the reasons for refraining
         from exercising, any such right. It is understood, however, that
         neither (A) the voting by Pledgor of any Pledged Shares for or
         Pledgor's consent to the election of directors at a regularly scheduled
         annual or other meeting of stockholders or with respect to incidental
         matters at any such meeting nor (B) Pledgor's consent to or approval of
         any action in the ordinary course of business or otherwise permitted
         under this Agreement shall be deemed inconsistent with the terms of
         this Agreement within the meaning of this Section 7(a)(i), and no
         notice of any such voting or consent need be given to Secured Party;

                  (ii)     Pledgor shall be entitled to receive and retain, and
         to utilize free and clear of the lien of this Agreement, any and all
         dividends and interest paid in respect of the Pledged Collateral;
         provided, however, that any and all

                           (A)      dividends and interest paid or payable other
                  than in cash in respect of, and instruments and other property
                  received, receivable or otherwise distributed in respect of,
                  or in exchange for, any Pledged Collateral,

                           (B)      dividends and other distributions paid or
                  payable in cash in respect of any Pledged Collateral in
                  connection with a partial or total liquidation or dissolution
                  or in connection with a reduction of capital, capital surplus
                  or paid-in-surplus, and

                           (C)      cash paid, payable or otherwise distributed
                  in respect of principal or in redemption of or in exchange for
                  any Pledged Collateral,

shall be, and shall forthwith be delivered to Secured Party to hold as, Pledged
Collateral and shall, if received by Pledgor, be received in trust for the
benefit of Secured Party, be segregated from the other property or funds of
Pledgor and be forthwith delivered to Secured Party as Pledged Collateral in the
same form as so received (with all necessary endorsements); and

                  (iii)    Secured Party shall promptly execute and deliver (or
         cause to be executed and delivered) to Pledgor all such proxies,
         dividend payment orders and other instruments as Pledgor may from time
         to time reasonably request for the purpose of

                                       6
<PAGE>

         enabling Pledgor to exercise the voting and other consensual rights
         which it is entitled to exercise pursuant to paragraph (i) above and to
         receive the dividends, principal or interest payments which it is
         authorized to receive and retain pursuant to paragraph (ii) above.

         (b)      Upon the occurrence and during the continuation of an Event of
Default:

                  (i)      upon written notice from Secured Party to Pledgor,
         all rights of Pledgor to exercise the voting and other consensual
         rights which it would otherwise be entitled to exercise pursuant to
         Section 7(a)(i) shall cease, and all such rights shall thereupon become
         vested in Secured Party who shall thereupon have the sole right to
         exercise such voting and other consensual rights;

                  (ii)     all rights of Pledgor to receive the dividends and
         interest payments which it would otherwise be authorized to receive and
         retain pursuant to Section 7(a)(ii) shall cease, and all such rights
         shall thereupon become vested in Secured Party who shall thereupon have
         the sole right to receive and hold as Pledged Collateral such dividends
         and interest payments; and

                  (iii)    all dividends, principal and interest payments which
         are received by Pledgor contrary to the provisions of paragraph (ii) of
         this Section 7(b) shall be received in trust for the benefit of Secured
         Party, shall be segregated from other funds of Pledgor and shall
         forthwith be paid over to Secured Party as Pledged Collateral in the
         same form as so received (with any necessary endorsements).

         (c)      In order to permit Secured Party to exercise the voting and
other consensual rights which it may be entitled to exercise pursuant to Section
7(b)(i) and to receive all dividends and other distributions which it may be
entitled to receive under Section 7(a)(ii) or Section 7(b)(ii), (i) Pledgor
shall promptly execute and deliver (or cause to be executed and delivered) to
Secured Party all such proxies, dividend payment orders and other instruments as
Secured Party may from time to time reasonably request and (ii) without limiting
the effect of the immediately preceding clause (i), Pledgor hereby grants to
Secured Party an irrevocable proxy to vote the Pledged Shares and to exercise
all other rights, powers, privileges and remedies to which a holder of the
Pledged Shares would be entitled (including, without limitation, giving or
withholding written consents of shareholders, calling special meetings of
shareholders and voting at such meetings), which proxy shall be effective,
automatically and without the necessity of any action (including any transfer of
any Pledged Shares on the record books of the issuer thereof) by any other
Person (including the issuer of the Pledged Shares or any officer or agent
thereof), upon the occurrence of an Event of Default and which proxy shall only
terminate upon the indefeasible payment in full of the Secured Obligations.

         SECTION 8. SECURED PARTY APPOINTED ATTORNEY-IN-FACT. Upon the
occurrence and during the continuation of an Event of Default, Pledgor hereby
irrevocably appoints Secured Party as Pledgor's attorney-in-fact, with full
authority in the place and stead of Pledgor and in the name of Pledgor, Secured
Party or otherwise, from time to time in Secured Party's discretion to take any
action and to execute any instrument that Secured Party may deem necessary or
advisable to accomplish the purposes of this Agreement, including without
limitation:

                                       7
<PAGE>

         (a)      to file one or more financing or continuation statements, or
amendments thereto, relative to all or any part of the Pledged Collateral
without the signature of Pledgor;

         (b)      to ask, demand, collect, sue for, recover, compound, receive
and give acquittance and receipts for moneys due and to become due under or in
respect of any of the Pledged Collateral;

         (c)      to receive, endorse and collect any instruments made payable
to Pledgor representing any dividend, principal or interest payment or other
distribution in respect of the Pledged Collateral or any part thereof and to
give full discharge for the same; and

         (d)      to file any claims or take any action or institute any
proceedings that Secured Party may deem necessary or desirable for the
collection of any of the Pledged Collateral or otherwise to enforce the rights
of Secured Party with respect to any of the Pledged Collateral.

         SECTION 9. SECURED PARTY MAY PERFORM. If Pledgor fails to perform any
agreement contained herein, Secured Party upon ten (10) days prior written
notice to Pledgor may itself perform, or cause performance of, such agreement,
and the reasonable expenses of Secured Party incurred in connection therewith
shall be payable by Pledgor.

         SECTION 10. STANDARD OF CARE. The powers conferred on Secured Party
hereunder are solely to protect its interest in the Pledged Collateral and shall
not impose any duty upon it to exercise any such powers. Except for the exercise
of reasonable care in the custody of any Pledged Collateral in its possession
and the accounting for moneys actually received by it hereunder, Secured Party
shall have no duty as to any Pledged Collateral, it being understood that
Secured Party shall have no responsibility for (a) ascertaining or taking action
with respect to calls, conversions, exchanges, maturities, tenders or other
matters relating to any Pledged Collateral, whether or not Secured Party has or
is deemed to have knowledge of such matters, (b) taking any necessary steps
(other than steps taken in accordance with the standard of care set forth above
to maintain possession of the Pledged Collateral) to preserve rights against any
parties with respect to any Pledged Collateral, (c) taking any necessary steps
to collect or realize upon the Secured Obligations or any guarantee therefor, or
any part thereof, or any of the Pledged Collateral, or (d) initiating any action
to protect the Pledged Collateral against the possibility of a decline in market
value. Secured Party shall be deemed to have exercised reasonable care in the
custody and preservation of Pledged Collateral in its possession if such Pledged
Collateral is accorded treatment substantially equal to that which Secured Party
accords its own property consisting of negotiable securities.

         SECTION 11. REMEDIES.

         (a)      If any Event of Default shall have occurred and be continuing,
Secured Party may exercise in respect of the Pledged Collateral, in addition to
all other rights and remedies provided for herein or otherwise available to it,
all the rights and remedies of a secured party on default under the Uniform
Commercial Code as in effect in the State of Tennessee (the "CODE") (whether or
not the Code applies to the affected Pledged Collateral), and Secured Party may
also in its sole discretion, without notice except as specified below, sell the
Pledged Collateral or any part thereof in one or more parcels at public or
private sale, at any exchange or broker's board or

                                       8
<PAGE>

at any of Secured Party's offices or elsewhere, for cash, on credit or for
future delivery, at such time or times and at such price or prices and upon such
other terms as Secured Party may deem commercially reasonable, irrespective of
the impact of any such sales on the market price of the Pledged Collateral.
Secured Party or any Bank may be the purchaser of any or all of the Pledged
Collateral at any such sale and Secured Party, as agent for and representative
of Banks, shall be entitled, for the purpose of bidding and making settlement or
payment of the purchase price for all or any portion of the Pledged Collateral
sold at any such public sale, to use and apply any of the Secured Obligations as
a credit on account of the purchase price for any Pledged Collateral payable by
Secured Party at such sale. Each purchaser at any such sale shall hold the
property sold absolutely free from any claim or right on the part of Pledgor,
and Pledgor hereby waives (to the extent permitted by applicable law) all rights
of redemption, stay and/or appraisal which it now has or may at any time in the
future have under any rule of law or statute now existing or hereafter enacted.
Pledgor agrees that, to the extent notice of sale shall be required by law, at
least ten days' notice to Pledgor of the time and place of any public sale or
the time after which any private sale is to be made shall constitute reasonable
notification. Secured Party shall not be obligated to make any sale of Pledged
Collateral regardless of notice of sale having been given. Secured Party may
adjourn any public or private sale from time to time by announcement at the time
and place fixed therefor, and such sale may, without further notice, be made at
the time and place to which it was so adjourned. Pledgor hereby waives any
claims against Secured Party arising by reason of the fact that the price at
which any Pledged Collateral may have been sold at such a private sale was less
than the price which might have been obtained at a public sale, even if Secured
Party accepts the first offer received and does not offer such Pledged
Collateral to more than one offeree. If the proceeds of any sale or other
disposition of the Pledged Collateral are insufficient to pay all the Secured
Obligations, Pledgor shall be liable for the deficiency and the fees of any
attorneys employed by Secured Party to collect such deficiency.

         (b)      Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act of 1933, as from time to time amended (the
"SECURITIES ACT"), and applicable state securities laws, Secured Party may be
compelled, with respect to any sale of all or any part of the Pledged Collateral
conducted without prior registration or qualification of such Pledged Collateral
under the Securities Act and/or such state securities laws, to limit purchasers
to those who will agree, among other things, to acquire the Pledged Collateral
for their own account, for investment and not with a view to the distribution or
resale thereof. Pledgor acknowledges that any such private sales may be at
prices and on terms less favorable than those obtainable through a public sale
without such restrictions (including, without limitation, a public offering made
pursuant to a registration statement under the Securities Act) and,
notwithstanding such circumstances, Pledgor agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner and that
Secured Party shall have no obligation to engage in public sales and no
obligation to delay the sale of any Pledged Collateral for the period of time
necessary to permit the issuer thereof to register it for a form of public sale
requiring registration under the Securities Act or under applicable state
securities laws, even if such issuer would, or should, agree to so register it.

         (c)      If Secured Party determines to exercise its right to sell any
or all of the Pledged Collateral, upon written request, Pledgor shall and shall
cause each issuer of any Pledged Shares to be sold hereunder from time to time
to furnish to Secured Party all such information as Secured Party may request in
order to determine the number of shares and other instruments

                                       9

included in the Pledged Collateral which may be sold by Secured Party in exempt
transactions under the Securities Act and the rules and regulations of the
Securities and Exchange Commission thereunder, as the same are from time to time
in effect.

         SECTION 12. APPLICATION OF PROCEEDS. Except as expressly provided
elsewhere in this Agreement, all proceeds received by Secured Party in respect
of any sale of, collection from, or other realization upon all or any part of
the Pledged Collateral may, in the discretion of Secured Party, be held by
Secured Party as Pledged Collateral for, and/or then, or at any time thereafter,
applied in full or in part by Secured Party against, the Secured Obligations in
the following order of priority:

                  FIRST:   To the payment of all costs and expenses of such
         sale, collection or other realization, including reasonable
         compensation to Secured Party and its agents and counsel, and all other
         expenses, liabilities and advances made or incurred by Secured Party in
         connection therewith, and all advances made by Secured Party hereunder
         for the account of Pledgor, and to the payment of all costs and
         expenses paid or incurred by Secured Party in connection with the
         exercise of any right or remedy hereunder;

                  SECOND:  To the payment of all other Secured Obligations (for
         the ratable benefit of the holders thereof) in such order as Secured
         Party shall elect; and

                  THIRD:   To the payment to or upon the order of Pledgor, or to
         whosoever may be lawfully entitled to receive the same or as a court of
         competent jurisdiction may direct, of any surplus then remaining from
         such proceeds.

         SECTION 13. CONTINUING SECURITY INTEREST; TRANSFER OF LOANS. This
Agreement shall create a continuing security interest in the Pledged Collateral
and shall (a) remain in full force and effect until the indefeasible payment in
full of all Secured Obligations, (b) be binding upon Pledgor, its successors and
assigns, and (c) inure, together with the rights and remedies of Secured Party
hereunder, to the benefit of Secured Party and its successors, transferees and
assigns. Without limiting the generality of the foregoing clause (c), any Bank
may assign or otherwise transfer any Loans held by it to any other Person, and
such other Person shall thereupon become vested with all the benefits in respect
thereof granted to Banks herein or otherwise. Upon the indefeasible payment in
full of all Secured Obligations, the security interest granted hereby shall
terminate and all rights to the Pledged Collateral shall revert to Pledgor. Upon
any such termination Secured Party will, at Pledgor's .expense, execute and
deliver to Pledgor such documents as Pledgor shall reasonably request to
evidence such termination and Pledgor shall be entitled to the return, upon its
request and at its expense, against receipt and without recourse to Secured
Party, of such of the Pledged Collateral as shall not have been sold or
otherwise applied pursuant to the terms hereof.

         SECTION 14. SECURED PARTY AS AGENT.

         (a)      Secured Party has been appointed to act as Secured Party
hereunder by Banks. Secured Party shall be obligated, and shall have the right
hereunder, to make demands, to give notices, to exercise or refrain from
exercising any rights, and to take or refrain from taking any

                                       10
<PAGE>

action (including, without limitation, the release or substitution of Pledged
Collateral), solely in accordance with this Agreement.

         (b)      Secured Party shall have the right to resign its duties
hereunder by giving Pledgor and the Banks fifteen (15) days written notice. Upon
notice of any Secured Party's resignation, the Banks shall appoint a successor
to the Secured Party who shall be a commercial bank or trust company reasonably
acceptable to Pledgor. If no successor is appointed by the Banks and found
acceptable to Pledgor by the twentieth (20th) business day after the date of
such notice of resignation, the Secured Party's resignation shall become
effective and the Banks shall thereafter perform all the duties of the Secured
Party hereunder until such time, if any, as the Banks appoint a successor to the
Secured Party as provided above and provided further that Banks' collective
expenses, costs and fees payable by Pledgor while acting as Secured Party
hereunder may not materially exceed those of the initial Secured Party. Upon the
acceptance of any appointment Secured Party hereunder, a successor Secured Party
shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Secured Party under this Agreement, and
the retiring Secured Party under this Agreement shall promptly (i) transfer to
such successor Secured Party all sums, securities and other items of Collateral
held hereunder, together with all records and other documents necessary or
appropriate in connection with the performance of the duties of the successor
Secured Party under this Agreement, and (ii) execute and deliver to such
successor Secured Party such amendments to financing statements, and take such
other actions, as may be necessary or appropriate in connection with the
assignment to such successor Secured Party of the security interests created
hereunder, whereupon such retiring Secured Party shall be discharged from its
duties and obligations under this Agreement. After any retiring Secured Party's
resignation hereunder as Secured Party, the provisions of this Agreement shall
inure to its benefit as to any actions taken or omitted to be taken by it under
this Agreement while it was Secured Party hereunder.

         SECTION 15. AMENDMENTS. No amendment or waiver of any provision of this
Agreement, or consent to any departure by Pledgor herefrom, shall in any event
be effective unless the same shall be in writing and signed by Secured Party,
and then such waiver or consent shall be effective only in the specific instance
and for the specific purpose for which it was given.

         SECTION 16. NOTICES. Any notice or other communication herein required
or permitted to be given shall be in writing and may be personally served,
telexed or sent by telefacsimile or United States mail or courier service and
shall be deemed to have been given when delivered in person or by courier
service, upon receipt of telefacsimile or telex, or three Business Days after
depositing it in the United States mail with postage prepaid and properly
addressed. For the purposes hereof, the address of each party hereto shall be as
set forth under such party's name on the signature pages hereof or, as to either
party, such other address as shall be designated by such party in a written
notice delivered to the other party hereto.

         SECTION 17. FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE. No
failure or delay on the part of Secured Party in the exercise of any power,
right or privilege hereunder shall impair such power, right or privilege or be
construed to be a waiver of any default or acquiescence therein, nor shall any
single or partial exercise of any such power, right or privilege preclude any
other or further exercise thereof or of any other power, right or

                                       11
<PAGE>

privilege. All rights and remedies existing under this Agreement are cumulative
to, and not exclusive of, any rights or remedies otherwise available.

         SECTION 18. SEVERABILITY. In case any provision in or obligation under
this Agreement shall be invalid, illegal or unenforceable in any jurisdiction,
the validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby.

         SECTION 19. HEADINGS. Section and subsection headings in this Agreement
are included herein for convenience of reference only and shall not constitute a
part of this Agreement for any other purpose or be given any substantive effect.

         SECTION 20. GOVERNING LAW; TERMS. THIS AGREEMENT SHALL BE GOVERNED BY,
AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE
STATE OF TENNESSEE, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES, EXCEPT TO
THE EXTENT THAT THE CODE PROVIDES THAT THE VALIDITY OR PERFECTION OF THE
SECURITY INTEREST HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR
PLEDGED COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE
STATE OF TENNESSEE. Unless otherwise defined herein, terms used in Articles 8
and 9 of the Uniform Commercial Code in the State of Tennessee are used herein
as therein defined.

         SECTION 21. CONSENT TO JURISDICTION AND SERVICE OF PROCESS. ALL
JUDICIAL PROCEEDINGS BROUGHT AGAINST PLEDGOR ARISING OUT OF OR RELATING TO THIS
AGREEMENT MUST BE BROUGHT IN AN APPROPRIATE FORUM IN NASHVILLE, DAVIDSON COUNTY,
TENNESSEE, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT PLEDGOR ACCEPTS FOR
ITSELF AND IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE
EXCLUSIVE JURISDICTION OF THE AFORESAID COURTS AND WAIVES ANY DEFENSE OF FORUM
NON CONVENIENS AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED
THEREBY IN CONNECTION WITH THIS AGREEMENT. Pledgor hereby agrees that service of
all process in any such proceeding in any such court may be made by registered
or certified mail, return receipt requested, to Pledgor at its address provided
in Section 16, and Pledgor hereby acknowledges that such service shall be
effective and binding in every respect. Nothing herein shall affect the right to
serve process in any other manner permitted by law.

         SECTION 22. WAIVER OF JURY TRIAL. PLEDGOR AND SECURED PARTY HEREBY
AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF
ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT. The scope of this waiver is
intended to be all-encompassing of any and all disputes that may be filed in any
court and that relate to the subject matter of this transaction, including
without limitation contract claims, tort claims, breach of duty claims, and all
other common law and statutory claims. Pledgor and Secured Party each
acknowledge that this waiver is a material inducement for Pledgor and Secured
Party to enter into a business relationship, that Pledgor and Secured Party have
already relied on this waiver in entering into this Agreement and that each will

                                       12
<PAGE>

continue to rely on this waiver in their related future dealings. Pledgor and
Secured Party further warrant and represent that each has reviewed this waiver
with its legal counsel, and that each knowingly and voluntarily waives its jury
trial rights following consultation with legal counsel. THIS WAIVER IS
IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING,
AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS
OR MODIFICATIONS TO THIS AGREEMENT. In the event of litigation, this Agreement
may be filed as a written consent to a trial by the court.

         SECTION 23. COUNTERPARTS. This Agreement may be executed in one or more
counterparts and by different parties hereto in separate counterparts, each of
which when so executed and delivered shall be deemed an original, but all such
counterparts together shall constitute but one and the same instrument;
signature pages may be detached from multiple separate counterparts and attached
to a single counterpart so that all signature pages are physically attached to
the same document.
