This release and discharge is intended to be broad and expansive, to release and waive any matter or CLAIM whatsoever, known or unknown, contingent or liquidated, direct or indirect.

3. COVENANT NOT TO SUE

a. Except as to enforcement of this AGREEMENT, CHEM-NUCLEAR covenants and agrees that it will forever refrain from instituting, prosecuting, maintaining or pressing any claim, action, suit, or proceeding against the STUDSVIK RELEASEES based in any way upon the CNS CONTRACT and/or because of any actions or omissions arising out of, related to, or in connection with the CLAIMS.

Except as to enforcement of this AGREEMENT, STUDSVIK covenants and agrees that it will forever refrain from instituting, prosecuting, maintaining or pressing any claim, action, suit, or proceeding against the CHEM-NUCLEAR RELEASEES based upon the CNS CONTRACT and/or because of any actions or omissions arising out of, related to, or in connection with the CLAIMS.

4. The B&CB and STUDSVIK agree that CHEM-NUCLEAR is not a necessary party, under Rule 19, South Carolina Rules of Civil Procedure, or otherwise, and that CHEM-NUCLEAR’S absence from the LAWSUIT as a result of this AGREEMENT does not prohibit in any way either STUDSVIK or the B&CB from asserting any of the CLAIMS and/or defenses either such PARTY has or may assert in this LAWSUIT.

5. STUDSVIK acknowledges and agrees that, subject to the CLAIMS STUDSVIK has asserted in the LAWSUIT, the IMPORTATION AGREEMENT bestows upon the B&CB an enforceable contractual right to pursue payment of invoices validly and accurately rendered to STUDSVIK for its disposal of WASTE at the SITE, and that neither this AGREEMENT nor CHEM-NUCLEAR’S dismissal from the LAWSUIT negates the B&CB’s right to pursue such payment, which is fully set forth in the IMPORTATION AGREEMENT.

6. Following execution of this AGREEMENT, the PARTIES’ counsel will take all necessary actions to file a STIPULATION OF DISMISSAL dismissing CHEM-NUCLEAR from the LAWSUIT without prejudice in the form attached as EXHIBIT A to this AGREEMENT.

7. The PARTIES agree that this AGREEMENT is a written stipulation between the PARTIES and their counsel, that any PARTY to this AGREEMENT may enter a copy of this executed AGREEMENT into the record of this LAWSUIT by filing it with the Clerk of Court, and that such filing shall satisfy the requirements of Rule 43(k), South Carolina Rules of Civil Procedure with regard to the binding effect of this AGREEMENT.

8. It is further understood and agreed that this AGREEMENT is the compromise of doubtful and disputed CLAIMS and that neither the negotiation of the terms, conditions or other provisions, nor the performance of this AGREEMENT, shall be (a) deemed or construed in any manner whatsoever to be an admission of liability by any PARTY hereto for any purpose, or (b) used by any PARTY hereto for any purpose other than the enforcement of the provisions hereof, provided, however, that nothing in this Paragraph shall affect the validity of the releases and other agreements set forth in this AGREEMENT.

9. The PARTIES represent that they have full authority to enter into, execute, and perform this AGREEMENT and to compromise the CLAIMS or potential CLAIMS referred to herein, that they are or represent the lawful owners of all CLAIMS being settled herein and have not assigned or transferred any of the CLAIMS released herein.

10. Each PARTY represents that it has determined that this AGREEMENT is fair and reasonable under all the circumstances and that this determination has been based solely upon independent judgment after reviewing this AGREEMENT in its entirety and consulting with counsel, and that, in making this determination, each has had an adequate opportunity to discuss and assess the merits of all CLAIMS or potential CLAIMS. Each PARTY further agrees that no fact, event, evidence, circumstance or transaction relating directly or indirectly to the CLAIMS, or which could have been asserted in the LAWSUIT, or which may hereafter be discovered, shall affect in any manner the final and unconditional nature of the Agreement and covenants set forth herein.

11. This AGREEMENT shall be binding upon the PARTIES and their heirs, executors, administrators, successors and assigns.

12. This AGREEMENT is deemed entered into in the State of South Carolina, and shall be construed and interpreted in accordance with the laws of the State of South Carolina.
