	(c)		To forbear from calling for additional collateral to secure the Loan or to secure any obligation comprised in the collateral securing the Loan.

	(d)		To consent to the substitution, exchange, or release of all or any part of the collateral securing the Loan, whether or not the collateral, if any, received by Lender upon such substitution, exchange or release shall be of the same or of a different character or value than the collateral surrendered by Lender.
	(e)		To forbear from realizing on any or all of the collateral securing the Loan as in its uncontrolled discretion Lender may deem proper.

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

	11.		The failure of any party, whether or not named or otherwise referred to as a party hereto, to sign or become obligated under this Subordination and Standby Agreement shall not effect the release or the liability of any party who is a signatory hereto.
