What Dealings with Debtor Exonerates Guarantor

A guarantor is exonerated, except so far as he may be indemnified by the principal, if by any act of the creditor, without the consent of the guarantor, the original obligation of the principal is altered in any respect, or the remedies or rights of creditor against the principal, in respect thereto, are in any way impaired or suspended.
