obligations and indebtedness (the "Debt") due to the Lender by the Debtor, under the terms of the Note and under the
following terms and conditions:


 


		1.	The Guarantor guarantees that the Debtors will promptly pay the full amount of principal and interest of the Note as and when
the same will in any manner be or become due, either according to the terms and conditions provided by the Note or upon acceleration
of the payment under the Note by reason of a default.



 


		2.	To the extent permitted by law, the Guarantor waives all defenses, counterclaims or offsets that are legally available to the
Guarantor with respect to the payment of the Debt of the Debtors.



 


		3.	The Lender is hereby authorized at any time, in its sole discretion and without notice, to take, change, release or in any
way deal with any security securing the Debt without in any way impairing the obligation of the Guarantor.



 


		4.	The Lender will be under no obligation to collect or to protect any such security or the Debt, and its neglect or failure to
collect or protect the security or the Debt is excused. Acceptance of the Guarantee is waived.



 


		5.	The Lender may grant extensions of time or other indulgences and otherwise deal with the Debtors and with other parties and
securities as the Lender may see fit without in any way limiting or lessening the liability of the Guarantor under this Agreement.



 


		6.	Any impairment of the security, which the Lender may from time to time hold as security for the Debt, will in no way operate
to discharge the Guarantor in whole or in part, it being specifically agreed that the Lender is not required to exercise diligence
to enforce its rights against the Debtor.



 


		7.	The Lender may release, surrender, exchange, modify, impair or extend the periods of duration or the time for performance or
payment of any collateral securing the obligations of the Debtors to the Lender, and may also settle or compromise any claim of
the Lender against the Debtors or against any other person or corporation whose obligation is held by the Lender as collateral
security for any obligation of the Debtors or the Lender.



 


		8.	This Guarantee is for the use and benefit of the Lender, and will also be for the use and benefit of any subsequent Lender
to whom the Lender may assign this Guarantee.

anytime later between the Lender and the Guarantor will be cumulative and not alternative, and will be in addition to all rights,
powers and remedies given to the Lender by law or in equity.



 


		13.	The Lender may, at its option, proceed in the first instance against the Guarantor to collect the obligations covered by this
Guarantee without first proceeding against any other person, firm or corporation and without resorting to any property held by
the Lender as collateral security.

the validity or enforceability of the remaining portions of this Guarantee or any part of this Guarantee.



 


		17.	No alteration or waiver of this Guarantee or of any of its terms, provisions or conditions will be binding upon the Lender
unless made in writing over the signature of the Lender or its representative.
