If it is at any time determined that either OCI or OTI is liable as a guarantor with respect to such Obligations arising in connection with Loan or advances made to the other (the "Guaranteed Obligations"), each of OCI and OTI hereby agrees to the following terms: (a) Obligations Absolute. No act or thing need occur to establish the liability of OCI or OTI for the Guaranteed Obligations, and no act or thing, except full payment and discharge of all such Guaranteed Obligations, shall in any way exonerate OCI or OTI or modify, reduce, limit or release the liability of OCI or OTI for its Guaranteed Obligations. The obligations of OCI or OTI for its Guaranteed Obligations shall be absolute, unconditional, and irrevocable, and shall not be subject to any right of setoff or counterclaim by OCI or OTI. (b) Continuing Guaranty . OCI and OTI shall each be liable for its Guaranteed Obligations, plus accrued interest thereon and all attorneys' fees, collection costs and enforcement expenses referable thereto. Guaranteed Obligations may be created and continued in any amount without affecting or impairing the liability of OCI or OTI therefor. No notice of such Guaranteed Obligations already or hereafter contracted or acquired by KTI, or any renewal or extension of any thereof need be given to OCI or OTI and none of the foregoing acts shall release OCI or OTI from liability hereunder. The agreement of OCI or OTI pursuant to the Credit Agreement with respect to its Guaranteed Obligations is an absolute, unconditional and continuing guaranty of payment of such Guaranteed Obligations and shall continue to be in force and be binding upon OCI or OTI until such Guaranteed Obligations are paid in full and the Credit Agreement is terminated, and KTI may continue, at any time and without notice to such Borrower, to extend credit or other financial accommodations and loan monies to or for the benefit of the other on the faith thereof. Each of OCI and OTI hereby waives, to the fullest extent permitted by law, any right they may have to revoke or terminate its guaranty of the Guaranteed Obligations before the Guaranteed Obligations are paid in full and the Credit Agreement is terminated. In the event either OCI or OTI shall have any right under applicable law to otherwise terminate or revoke its guaranty of the Guaranteed Obligations which cannot be waived, such termination or revocation shall not be effective until written notice of such termination or revocation, signed by person, is actually received by KTI's officer responsible for such matters. Any notice of termination or revocation described above shall not affect OCI's or OTI's guaranty of the Guaranteed Obligations in relation to (i) any of the Guaranteed Obligations that arose prior to receipt thereof or (ii) any of the Guaranteed Obligations created after receipt thereof, if such Guaranteed Obligations were incurred through loans by KTI , and/or for the purpose of protecting any collateral, including, but not limited, to all protective advances, costs, expenses, and attorneys' and paralegals' fees, whensoever made, advanced or incurred by KTI in connection with the Guaranteed Obligations. If, in reliance on either OCI or OTI's guaranty of its 11 Guaranteed Obligations, KTI makes loans or other advances to or for the benefit of the other or takes other action under this Agreement after such aforesaid termination or revocation by the undersigned but prior to the receipt by KTI of said written notice as set forth above, the rights of KTI shall be the same as if such termination or revocation had not occurred. (c) Other Transactions. Whether or not any existing relationship between OCI and OTI has been changed or ended, KTI may, but shall not be obligated to, enter into transactions resulting in the creation or continuance of other obligations of the other to KTI, without consent or approval by the other and without notice to the other, and all such obligations shall be guaranteed by virtue of the Credit Agreement. The liability of OCI and OTI under the Credit Agreement with respect to the Guaranteed Obligations shall not be affected or impaired by any of the following acts or things (which KTI is expressly authorized to do, omit or suffer from time to time, without notice to or approval by OCI or OTI): (i) any acceptance of collateral security, other guarantors, accommodation parties or sureties for any or all Guaranteed Obligations; (ii) any one or more extensions or renewals of Guaranteed Obligations (whether or not for longer than the original period) or any modification of the interest rates, maturities or other contractual terms applicable to any Guaranteed Obligations; (iii) any waiver or indulgence granted to the other Borrowers, any delay or lack of diligence in the enforcement of Guaranteed Obligations, or any failure to institute proceedings, file a claim, give any required notices or otherwise protect any Guaranteed Obligations; (iv) any full or partial release of, settlement with, or agreement not to sue,OCI or OTI or any other guarantor or other person liable in respect of any Guaranteed Obligations; (v) any discharge of any evidence of Guaranteed Obligations or the acceptance of any instrument in renewal thereof or substitution therefor; (vi) any failure to obtain collateral security for Guaranteed Obligations, or to see to the proper or sufficient creation and perfection thereof, or to establish the priority thereof, or to protect, ensure, or enforce any collateral security, or any modification, substitution, discharge, impairment or loss of any collateral security; (vii) any foreclosure or enforcement of any collateral security; (viii) any transfer of any Guaranteed Obligations or any evidence thereof; (ix) any order of application of any payments or credits upon Guaranteed Obligations; (x) any release of any collateral security for Guaranteed Obligations; (xi) any amendment to or modification of, any agreement between KTI and either OCI or OTI, or any waiver of compliance by OCI or OTI with the terms thereof; and (xii) any election by KTI under Section 1111(b) of the United States Bankruptcy Code. (d) Waivers of Defenses and Rights. Each of OCI and OTI waives any and all defenses, claims and discharges of the other, or any other obligor, pertaining to the Guaranteed Obligations, except the defense of discharge by payment in full. Without limiting the generality of the foregoing, neither OCI nor OTI will assert, plead or enforce against KTI any defense of waiver, release, discharge in bankruptcy, statute of limitations, res judicata, statute of frauds, anti-deficiency statute, fraud, usury, illegality or unenforceability which may be available to OCI or OTI or any other person liable in respect of any Guaranteed Obligations, or any setoff available against KTI to OCI or 12 OTI or any such other person, whether or not on account of a related transaction. Each of OCI and OTI expressly agrees that it shall be and remain liable for any deficiency remaining after foreclosure of any security interest securing Guaranteed Obligations, whether or not the liability of or any other obligor for such deficiency is discharged pursuant to statute, judicial decision or contract. Each of OCI and OTI waives presentment, demand for payment, notice of dishonor or nonpayment, and protest of any instrument evidencing Guaranteed Obligations. Each of OCI and OTI agrees that its liability under the Credit Agreement for the Guaranteed Obligations shall be primary and direct, and that KTI shall not be required first to resort for payment of the Guaranteed Obligations to the other or other persons or their properties, or first to enforce, realize upon or exhaust any collateral security for the Guaranteed Obligations, or to commence any action or obtain any judgment against any other or against any such collateral security or to pursue any other right or remedy KTI may have against any other before enforcing the liability of such Person for the Guaranteed Obligations under the Credit Agreement. (e) Approval of Credit. Each of OCI and OTI has, independently and without reliance upon KTI or the directors, officers, agents or employees of KTI, and instead in reliance upon information furnished by the other Borrowers and upon such other information as OCI or OTI deemed appropriate, made its own independent credit analysis and decision to guaranty the obligations of the other Borrowers pursuant to the Credit Agreement. (f) Waiver of Subrogation. Each of OCI and OTI expressly waives any and all rights of subrogation, reimbursement, indemnity, exoneration, contribution or any other claim which it may now or hereafter have against the other, any endorser or any other guarantor of all or any part of the Guaranteed Obligations, and each hereby waives any benefit of, and any right to participate in, any security or collateral given to KTI to secure payment of the Guaranteed Obligations or any other liability of the other to KTI. Each of OCI and OTI further agrees that any and all claims it may have against the other, any endorser or any other guarantor of all or any part of the Guaranteed Obligations or against any of their respective properties, whether arising by reason of any payment by such Person to KTI pursuant to the provisions hereof or otherwise, is hereby waived.
