undersigned shall cause to be transferred by wire a non-refundable good faith
deposit of one thousand dollars ($1,000) to the CSA. Such deposit shall be
applied in full to the repurchase price of said debenture and shall be forfeited
if undersigned fails to pay the designated total prepayment amount to the CSA on

appointment of a receiver or liquidator, whether voluntary or involuntary, for
the Undersigned or for any of its property, or upon the filing of a petition by
or against the Undersigned under the provisions of any State or Federal
insolvency law or under the provisions of the Bankruptcy Code of 1978 or upon
the making by the Undersigned of an assignment for the benefit of its
creditors. Payee with the consent of SBA, or SBA as assignee is authorized to

Indebtedness when due, (2) nonperformance by the Undersigned of any agreement
with, or any condition imposed by, the development company or SBA, (3) failure
of the Undersigned or any person acting on behalf of the Undersigned to disclose
any material fact, in any application, declaration or other document delivered

of the Undersigned in such document; (4) the reorganization, merger or
consolidation of the Undersigned without

                                      -2-
<PAGE>

prior written consent of the development company and SBA, or the making of an
agreement therefor; (5) the sale of the Collateral, or any part of it or any
interest in it, or any agreement that the Collateral will be alienated by the
Undersigned, or any alienation of the Collateral by operation of law or
otherwise; (6) the Undersigned's failure duly to account, to Payee's or SBA's
(as assignee) satisfaction, at such time or times as may be required, for any of
the Collateral, or proceeds thereof, coming into the control of the Undersigned;
(7) the institution of any suit affecting the Undersigned deemed by SBA to
affect adversely its interest hereunder in the Collateral or otherwise; (8) any
change, without prior written approval by SBA, affecting ten or more percent in
the legal or equitable ownership of the Undersigned; (9) any change in the
respective ownerships of the Undersigned; (10) if the Undersigned and/or its
affillates acquire directly or indirectly an ownership interest of ten or more
percent in the development company; (11) any other event prohibited by the
related security or other instruments; or (12) any violation by the Undersigned
of SBA regulations. Payee's or SBA's as assignee failure to exercise its rights
under this paragraph shall not constitute a waiver thereof. Upon acceleration
pursuant to this paragraph, the indebtedness shall be computed in the same
manner as is set forth for the prepayment amount in the preceding paragraph
captioned "Prepayment".

Collateral
----------

Upon the nonpayment of the Indebtedness, or any part thereof, when due, whether
by acceleration or otherwise, Payee with SBA's consent or SBA as assignee is
empowered to sell, assign, and deliver the whole or any part of the collateral
at public or private sale.  After deducting all expenses incidental to such
sale or sales, Payee or SBA as assignee may apply the proceeds thereof to the
payment of the Indebtedness as it shall deem proper.  The Undersigned hereby
waives all rights to redemption or appraisement whether before or after sale.
Payee with SBA's consent or SBA as assignee is further empowered, to convert
into money all or any part of the Collateral, by suit or otherwise, and to
surrender, compromise, release, renew, extend, exchange, or substitute any item
of the Collateral in transactions with the Undersigned or any third party.
Whenever any item of the Collateral shall not be paid when due, or otherwise
shall be in default, whether or not the Indebtedness, or any part thereof, has
become due, Payee or SBA as assignee shall have the same rights and powers with
respect to such item of the Collateral as are granted in respect thereof in this
paragraph in case of nonpayment of the Indebtedness, or any part thereof, when
due.  None of the rights, remedies, privileges, or powers of Payee or SBA as
assignee expressly provided for herein shall be exclusive, but each of them
shall be cumulative with and in addition to every other such power now or
hereafter existing in favor of Payee or SBA as assignee, whether at law or in
equity, by statute or otherwise.

The Undersigned agrees to take all necessary steps to administer, supervise,
preserve, and protect the Collateral; and regardless of any action taken by
Payee or SBA as assignee, there shall be no duty upon Payee or SBA as assignee
in this respect. The Undersigned shall pay all expenses of any nature, including
but not limited to reasonable attorney's fees and costs, which Payee or SBA as
assignee may deem necessary in connection with the satisfaction of the
Indebtedness or the administration, preservation (including, but not limited to,
adequate insurance of), or the realization upon the Collateral. Payee with SBA's
consent or SBA as assignee is authorized to pay at any time and from time to
time any or all of such expenses, add the amount of such payment to the amount
of the Indebtedness, and charge interest thereon at the rate specified herein
with respect to the principal amount of this Note.

The security rights of Payee or SBA as assignee hereunder shall not be impaired
by any indulgence, including but not limited to (a) any renewal,

                                      -3-

<PAGE>

extension, or modification which Payee or SBA as assignee may grant with respect
to the Indebtedness or any part thereof, or (b) any surrender, compromise,
release, exchange, or substitution which Payee or SBA as assignee may grant in
respect of the Collateral, or (c) any indulgence granted in respect to any
endorser, guarantor, or surety. The Payee or SBA as assignee of this Note, the
Collateral, any guaranty, and any other document (or any of them), sold,
transferred, or pledged, shall forthwith become vested with and entitled to
exercise all the powers and rights given by this Note as if said purchaser,
transferee, or pledgee were originally named as Payee in this Note.

     a.   Borrower will at all times keep proper books of account in a manner
satisfactory to Lender and/or SBA. Borrower hereby authorizes Lender or SBA to

following the expiration of any such period) and at

                                       6

<PAGE>

such other times and in such form as Lender may prescribe, Borrower's financial

information relating to the conditions and affairs of Borrower and any desired
information from reports, returns, files and records of such authorities upon
request therefrom by Lender and SBA. Lender shall be given free access to the
Real Estate for the purpose of such inspection or audits and also for the
purpose of determining the condition of the premises.

     b.   Borrrower will deliver to Lender within fifteen (15) days after any
written request therefore from Lender such information as may be reasonably

interest on all indebtedness heretofore or hereafter incurred or assumed by it
when and as the same shall become due and payable, unless such indebtedness be
renewed or extended, and will observe, perform and discharge all of the
covenants, conditions, and obligations which are imposed on it by and all
indentures and other agreements securing or evidencing so to prevent an
occurrence of any act of omission which under the provisions thereof may be
declared to be default thereunder which may result in a lien placed upon the
Real Estate.

     g.   Borrower will at all times cause all of the property to be maintained
and kept in such condition and repair that Lender's security will be adequately

     h.   In the event that any provision of this Agreement or any other

circumstances shall be declared null and void, invalid or held for any reason to
be unenforceable by a Court of competent jurisdiction, the remainder of such

     i.   All of the building improvements upon the Real Estate which are of
insurable character will be kept insured by financially sound and reputable

<PAGE>

is required, Borrower must purchase and maintain Federal Flood Insurance in
amounts and coverages equal to the lesser of the outstanding principal balance
of the Loan, the value of the property to be insured or the maximum limit of
coverage available. Notwithstanding, if Flood Insurance becomes required during
the life of the Loan, Borrower must purchase same. Failure to maintain any
required Flood Insurance will cause the Borrower to become ineligible for any
further flood disaster assistance.

     n.   Borrower shall at all times during the term of this Loan, or any
extension thereof, maintain life insurance on the life of Nicholas Tsengas in an

therefrom, in a form and with an insurance company satisfactory to Lender, with
loss payable clause on the personal property and New York Standard Mortgage
Clause or its equivalent on real estate to Lender.

     p.   While the outstanding principal balance of the loan is TWO HUNDRED
THOUSAND DOLLARS ($200,000.00) or more, Borrower shall provide Lender a "review"
year-end financial statement of the Borrower prepared by an independent public
accountant within ninety (90) days, of the close of Borrower's fiscal year,
ending December 31st.

     q.   Prior to disbursement, Borrower shall provide evidence that it
complies with Environmental Protection Agency requirements.

     r.   Borrower shall inject the sum of SIXTY FIVE THOUSAND DOLLARS
($65,000.00) prior to any disbursement of this loan, in the form of cash or
kind, acceptable to SBA; if any of said funds are loaned, repayment terms must
be for a term equal, at least, to the terms of this agreement, and be
subordinate to the liens securing this loan. If any portion of said funds are

instruments. This injection may not be repaid at a rate faster than the SBA
debenture.

4.   Debtor shall keep, store or regularly garage all Collateral at locations
approved by Secured Party in writing.

5.   Debtor shall not conduct business under any other name than that given
above nor change or reorganize the type of business entity under which it does
business except upon prior written approval of Secured Party. If such approval
is given, Debtor guarantees that all documents, instruments and agreements
demanded by Secured Party shall be prepared and filed at Debtor's expense
before such change of name or business entity occurs.

6.   Debtor shall pay the filing and recording costs of any documents or
instruments necessary to perfect, extend, modify, or terminate the security
interest created hereunder, as demanded by Secured Party.

7.   Debtor shall maintain all Collateral in good condition, pay promptly all
taxes, judgments, or changes of any kind levied or assessed thereon, keep
current all rent due on premises where Collateral is located, and maintain
insurance on all Collateral against such hazards, in such amounts and with such
companies as Secured Party may demand, all such insurance policies to be in the
possession of Secured Party and to contain a Lender's Loss Payable Clause naming
Secured Party in a manner satisfactory to Secured Party. Debtor hereby assigns
to Secured Party any proceeds of such policies and all unearned premiums
thereon, and authorizes and empowers Secured Party to collect such sums and to
execute and endorse in Debtor's name all proofs of loss, drafts, checks and any
other documents necessary to accomplish such collections, and any persons or
entities making payments to Secured Party under the terms of this Paragraph are
hereby relieved absolutely from any obligation to see to the application of any
sums so paid.

8.   Debtor shall be in default hereunder if Debtor fails to perform any of the
liabilities imposed hereby or any other obligation required by the various
instruments or papers evidencing or securing this loan, or if the full balance
of the loan becomes immediately payable under the terms of such instruments,
either automatically or by declaration of the Secured Party. In the event of any
default, Secured Party may, in its own discretion, cure such default and, if it
does so, any expenditures made for such purpose shall be added to the principal
of the Note.

9.   In the event of default, Debtor shall assemble and make available all
Collateral at any place designated by Secured Party. Debtor acknowledges being
advised of a constitutional right to a court notice and hearing to determine
whether, upon default, there is probable cause to sustain the validity of the
Secured Party's claim and whether the Secured Party is entitled to possession of
the Collateral and being so advised, Debtor hereby voluntarily gives up, waives
and surrenders any right to a notice and hearing to determine whether there is
probable cause to sustain the validity of Secured Party's Claim. Any notices
required pursuant to any state or local law shall be deemed reasonable if mailed
by Secured Party to the Persons entitled thereto at their last known addresses
at least ten days prior to disposition of the Collateral, and, in reference to a
private sale, need state only that Secured Party intends to negotiate such a
sale. Disposition of Collateral shall be deemed commercially reasonable if made
pursuant to a public offering advertised at least twice in a newspaper of
general circulation in the community where the Collateral is located or by a
private sale for a sum equal to or in excess of the liquidation value of the
Collateral as determined by Secured Party.

10.  All rights conferred on Secured Party hereby are in addition to those
granted to it by any state or local law or any other law. Failure or repeated
failure to enforce any rights hereunder shall not constitute an estoppel or
waiver of Secured Party's rights to exercise such rights accruing prior or
subsequent thereto. Secured Party shall not be liable for any loss to Collateral
in its possession, nor shall such loss diminish the debt due, even if the loss
is caused or contributed to by Secured Party's negligence.

                                                        July 8, 1993

     In order to induce Lake County Small Business Assistance Corporation,
                        -------------------------------------------------
(hereinafter (SBA or other Lending Institution) called "Lender") to make a loan
or loans, or renewal or extension thereof, to Napro, Inc. (hereinafter called
"Debtor"), the Undersigned hereby unconditionally guarantees to Lender, its
successors and assigns, the due and punctual payment when due, whether by
acceleration or otherwise, in accordance with the terms thereof, of the
principal of and interest on and all other sums payable, or stated to be
payable, with respect to the note of the Debtor, made by the Debtor to Lender,
dated July 8, 1993 in the principal amount of $270,000.00 , with interest at the
rate of ___________________ per cent per annum. Such note, and the interest
thereon and all other sums payable with respect thereto are hereinafter
collectively called "Liabilities." As security for the performance of this
guaranty the Undersigned hereby mortgages, pledges, assigns, transfers and
delivers to Lender certain collateral (if any), listed in the schedule on the
reverse side hereof. The term "collateral" as used herein shall mean any funds,
guaranties, agreements or other property or rights or interests of any nature
whatsoever, or the proceeds thereof, which may have been, are, or hereafter may
be, mortgaged, pledged, assigned, transferred or delivered directly or
indirectly by or on behalf of the Debtor or the Undersigned or any other party
to Lender or to the holder of the aforesaid note of the Debtor, or which may
have been, are, or hereafter may be held by any party as trustee or otherwise as
security, whether immediate or underlying, for the performance of this guaranty
or the payment of the Liabilities or any of them or any security therefor.
________________________________________________________________________________

     The Undersigned waives any notice of the incurring by the Debtor at any
time of any of the Liabilities, and waives any and all presentment, demand,
protest or notice of dishonor, nonpayment, or other default with respect to any
of the Liabilities and any obligation of any party at any time comprised in the
collateral. The Undersigned hereby grants to Lender full power, in its
uncontrolled discretion and without notice to the undersigned, but subject to
the provisions of any agreement between the Debtor or any other party and Lender
at the time in force, to deal in any manner with the Liabilities and the
collateral, including, but without limiting the generality of the foregoing, the
following powers:

     (a)  To modify or otherwise change any terms of all or any part of the
          Liabilities or the rate of interest thereon (but not to increase the
          principal amount of the note of the Debtor to Lender), to grant any
          extension or renewal thereof and any other indulgence with respect
          thereto, and to effect any release, compromise or settlement with
          respect thereto;

     (b)  To enter into any agreement of forbearance with respect to all or any
          part of the Liabilities, or with respect to all or any part of the
          collateral, and to change the terms of any such agreement;

     (c)  To forbear from calling for additional collateral to secure any of the
          Liabilities or to secure any obligation comprised in the collateral;

     (d)  To consent to the substitution, exchange, or release of all or any
          part of the collateral, whether or not the collateral, if any,
          received by Lender upon any such substitution, exchange, or release
          shall be of the same or of a different character or value than the
          collateral surrendered by Lender;

     (e)  In the event of the nonpayment when due, whether by acceleration or
          otherwise, of any of the Liabilities, or in the event of default in
          the performance of any obligation comprised in the collateral, to
          realize on the collateral or any the part thereof, as a whole or in
          such parcels or subdivided interests as Lender may elect, at any
          public or private sale or sales, for cash or on credit or for future
          delivery, without demand, advertisement or notice of the time or place
          of sale or any adjournment thereof (the Undersigned hereby waiving any
          such demand, advertisement and notice to the extent permitted by law),
          or by foreclosure or otherwise, or to forbear from realizing thereon,
          all as Lender in its uncontrolled discretion may deem proper, and to
          purchase all or any part of the collateral for its own account at any
          such sale or foreclosure, such powers to be exercised only to the
          extent permitted by law.

     The obligations of the Undersigned hereunder shall not be released,
discharged or in any way affected, nor shall the Undersigned have any rights or
recourse against Lender, by reason of any action Lender may take or omit to take
under the foregoing powers.

     In case the Debtor shall fail to pay all or any part of the Liabilities
when due, whether by acceleration or otherwise, according to the terms of said
note, the Undersigned, immediately upon the written demand of Lender, will pay
to Lender the amount due and unpaid by the Debtor as aforesaid, in like manner
as if such amount constituted the direct and primary obligation of the
Undersigned. Lender shall not be required, prior to any such demand on, or
payment by, the Undersigned, to make any demand upon or pursue or exhaust any of
its rights or remedies against the Debtor or others with respect to the payment
of any of the Liabilities, or to pursue or exhaust any of its rights or remedies
with respect to any part of the collateral. The Undersigned shall have no right
of subrogation whatsoever with respect to the Liabilities or the collateral
unless and until Lender shall have received full payment of all the Liabilities.
<PAGE>

     The obligations of the Undersigned hereunder, and the rights of Lender in
the collateral, shall not be released, discharged or in any way affected, nor
shall the Undersigned have any rights against Lender; by reason of the fact that
any of the collateral may be in default at the time of acceptance thereof by
Lender or later; nor by reason of the fact that a valid lien in any of the
collateral may not be conveyed to, or created in favor of, Lender; nor by reason
of the fact that any of the collateral may be subject to equities or defenses or
claims in favor of others or may be invalid or defective in any way; nor by
reason of the fact that any of the Liabilities may be invalid for any reason
whatsoever; nor by reason of the fact that the value of any of the collateral,
or the financial condition of the Debtor or of any obligor under or guarantor of
any of the collateral, may not have been correctly estimated or may have changed
or may hereafter change; nor by reason of any deterioration, waste, or loss by
fire, theft, or otherwise of any of the collateral, unless such deterioration,
waste, or loss be caused by the willful act or willful failure to act of Lender.

     The Undersigned agrees to furnish Lender, or the holder of the aforesaid
note of the Debtor, upon demand, but not more often than semiannually, so long
as any part of the indebtedness under such note remains unpaid ,a financial
statement setting forth, in reasonable detail, the assets, liabilities, and net
worth of the Undersigned.

     The Undersigned acknowledges and understands that if the Small Business
Administration (SBA) enters into, has entered into, or will enter into, a
Guaranty Agreement, with Lender or any other lending institution, guaranteeing a
portion of Debtor's Liabilities, the Undersigned agrees that it is not a
coguarantor with SBA and shall have no right of contribution against SBA. The
Undersigned further agrees that all liability hereunder shall continue
notwithstanding payment by SBA under its Guaranty Agreement to the other lending
institution.

     The term "Undersigned" as used in this agreement shall mean the signer or
signers of this agreement, and such signers, if more than one, shall be jointly
and severally liable hereunder. The Undersigned further agrees that all
liability hereunder shall continue notwithstanding the incapacity, lack of
authority, death, or disability of any one or more of the Undersigned, and that
any failure by Lender or its assigns to file or enforce a claim against the
estate of any of the Undersigned shall not operate to release any other of the
Undersigned from liability hereunder. The failure of any other person to sign
this guaranty shall not release or affect the liability of any signer hereof.

                        -------------------------------------------------
                          (SBA or other Lending Institution)

(hereinafter called "Lender") to make a loan or loans, or renewal or extension
thereof, to Napro, Inc. (hereinafter called "Debtor"), the Undersigned hereby
unconditionally guarantees to Lender, its successors and assigns, the due and
punctual payment when due, whether by acceleration or otherwise, in accordance
with the terms thereof, of the principal of and interest on and all other sums
payable, or stated to be payable, with respect to the note of the Debtor, made
by the Debtor to Lender, dated July 8, 1993 in the principal amount of
$270,000.00, with interest at the rate of __________________________________ per
cent per annum. Such note, and the interest thereon and all other sums payable
with respect thereto are hereinafter collectively called "Liabilities." As
security for the performance of this guaranty the Undersigned hereby mortgages,
pledges, assigns, transfers and delivers to Lender certain collateral (if any),
listed in the schedule on the reverse side hereof. The term "collateral" as used
herein shall mean any funds, guaranties, agreements or other property or rights
or interests of any nature whatsoever, or the proceeds thereof, which may have
been, are, or hereafter may be, mortgaged, pledged, assigned, transferred or
delivered directly or indirectly by or on behalf of the Debtor or the
Undersigned or any other party to Lender or to the holder of the aforesaid note
of the Debtor, or which may have been, are, or hereafter may be held by any
party as trustee or otherwise, as security, whether immediate or underlying, for
the performance of this guaranty or the payment of the Liabilities or any of
them or any security therefor.
--------------------------------------------------------------------------------
     The Undersigned waives any notice of the incurring by the Debtor at any
time of any of the Liabilities, and waives any and all presentment, demand,
protest or notice of dishonor, nonpayment, or other default with respect to any
of the Liabilities and any obligation of any party at any time comprised in the
collateral. The Undersigned hereby grants to Lender full power, in its
uncontrolled discretion and without notice to the undersigned, but subject to
the provisions of any agreement between the Debtor or any other party and Lender
at the time in force, to deal in any manner with the Liabilities and the
collateral, including, but without limiting the generality of the foregoing, the
following powers:

     (a) To modify or otherwise change any terms of all or any part of the
         Liabilities or the rate of interest thereon (but not to increase the
         principal amount of the note of the Debtor to Lender), to grant any
         extension or renewal thereof and any other indulgence with respect
         thereto, and to effect any release, compromise or settlement with
         respect thereto;

     (b) To enter into any agreement of forbearance with respect to all or any
         part of the Liabilities, or with respect to all or any part of the
         collateral, and to change the terms of any such agreement;

     (c) To forbear from calling for additional collateral to secure any of the
         Liabilities or to secure any obligation comprised in the collateral;

     (d) To consent to the substitution, exchange, or release of all or any part
         of the collateral, whether or not the collateral, if any, received by
         Lender upon any such substitution, exchange, or release shall be of the
         same or of a different character or value than the collateral
         surrendered by Lender;

     (e) In the event of the nonpayment when due, whether by acceleration or
         otherwise, of any of the Liabilities, or in the event of default in the
         performance of any obligation comprised in the collateral, to realize
         on the collateral or any part thereof, as a whole or in such parcels or
         subdivided interests as Lender may elect, at any public or private sale
         or sales, for cash or on credit or for future delivery, without demand,
         advertisement or notice of the time or place of sale or any adjournment
         thereof (the Undersigned hereby waiving any such demand, advertisement
         and notice to the extent permitted by law), or by foreclosure or
         otherwise, or to forbear from realizing thereon, all as Lender in its
         uncontrolled discretion may deem proper, and to purchase all or any
         part of the collateral for its own account at any such sale or
         foreclosure, such powers to be exercised only to the extent permitted
         by law.

     The obligations of the Undersigned hereunder shall not be released,
discharged or in any way affected, nor shall the Undersigned have any rights or
recourse against Lender, by reason of any action Lender may take or omit to take
under the foregoing powers.

     In case the Debtor shall fail to pay all or any part of the Liabilities
when due, whether by acceleration or otherwise, according to the terms of said
note, the Undersigned, immediately upon the written demand of Lender, will pay
to Lender the amount due and unpaid by the Debtor as aforesaid, in like manner
as if such amount constituted the direct and primary obligation of the
Undersigned. Lender shall not be required, prior to any such demand on, or
payment by, the Undersigned, to make any demand upon or pursue or exhaust any of
its rights or remedies against the Debtor or others with respect to the payment
of any of the Liabilities, or to pursue or exhaust any of its rights or remedies
with respect to any part of the collateral. The Undersigned shall have no right
of subrogation whatsoever with respect to the Liabilities or the collateral
unless and until Lender shall have received full payment of all the Liabilities.

<PAGE>

     The obligations of the Undersigned hereunder, and the rights of Lender in
the collateral, shall not be released, discharged or in any way affected, nor
shall the Undersigned have any rights against Lender: by reason of the fact that
any of the collateral may be in default at the time of acceptance thereof by
Lender or later; nor by reason of the fact that a valid lien in any of the
collateral may not be conveyed to, or created in favor of, Lender; nor by reason
of the fact that any of the collateral may be subject to equities or defenses or
claims in favor of others or may be invalid or defective in any way; nor by
reason of the fact that any of the Liabilities may be invalid for any reason
whatsoever; nor by reason of the fact that the value of any of the collateral,
or the financial condition of the Debtor or of any obligor under or guarantor of
any of the collateral, may not have been correctly estimated or may have changed
or may hereafter change; nor by reason of any deterioration, waste, or loss by
fire, theft, or otherwise of any of the collateral, unless such deterioration,
waste, or loss be caused by the willful act or willful failure to act of Lender.

     The Undersigned agrees to furnish Lender, or the holder of the aforesaid
note of the Debtor, upon demand, but not more often than semiannually, so long
as any part of the indebtedness under such note remains unpaid, a financial
statement setting forth, in reasonable detail, the assets, liabilities, and net
worth of the Undersigned.

     The Undersigned acknowledges and understands that if the Small Business
Administration (SBA) enters into, has entered into, or will enter into, a
Guaranty Agreement, with Lender or any other lending institution, guaranteeing a
portion of Debtor's Liabilities, the Undersigned agrees that it is not a
coguarantor with SBA and shall have no right of contribution against SBA. The
Undersigned further agrees that all liability hereunder shall continue
notwithstanding payment by SBA under its Guaranty Agreement to the other lending
institution.

     The term "Undersigned" as used in this agreement shall mean the signer or
signers of this agreement, and such signers, if more than one, shall be jointly
and severally liable hereunder. The Undersigned further agrees that all
liability hereunder shall continue notwithstanding the incapacity, lack of
authority, death, or disability of any one or more of the Undersigned, and that
any failure by Lender or its assigns to file or enforce a claim against the
estate of any of the Undersigned shall not operate to release any other of the
Undersigned from liability hereunder. The failure of any other person to sign
this guaranty shall not release or affect the liability of any signer hereof.
