officers, directors, employees, agents, successors and assigns (Aerojet and such persons are collectively hereinafter referred to as “Aerojet’s Indemnified Persons”) harmless from and against any and all loss, liability, damage or deficiency (including reasonable attorneys’ fees) (collectively “Losses”) that Aerojet’s Indemnified Persons may suffer, sustain, incur or become subject to, caused by or due to: (a) any breach of any representation or warranty of DMC/SF in this Agreement; (b) the failure to perform any covenant, undertaking, agreement or other obligation of DMC/SF under this Agreement; (c) any Excluded Asset; or (d) any Retained Liability.

Subject to the limits set forth in this Article5, Aerojet agrees to indemnify, defend and hold DMC/SF and DMC/SF’s Affiliates, officers, directors, employees, agents, successors and assigns (DMC/SF and such persons are hereinafter collectively referred to as “DMC/SF’s Indemnified Persons”), harmless from and against any and all Losses that DMC/SF’s Indemnified Persons may suffer, sustain, incur or become subject to, caused by or due to: (a) any breach of any representation or warranty of Aerojet in this Agreement; (b) the failure to perform any covenant, undertaking, agreement or other obligation of Aerojet under this Agreement; or (c) the ownership, operations or control of the Business after the Closing or (d) any of the Acquired Assets after they have been delivered from DMC/SF to Aerojet.

5.3 Survival of Representations and Warranties; Deductible. The several representations and warranties of the parties contained in this Agreement and the parties’ right to indemnity in accordance with this Article 5 shall survive the Closing Date and shall remain in full force and effect thereafter as follows: with respect to Article 3 (except for Article 3.10) for a period of 12 months after the Closing Date; with respect to Article 3.10 upon the earlier of (i) the termination of the Sublease or (ii) the assumption by Aerojet of the Master Lease (as defined in the Sublease); for all other representations and warranties, for a period of 12 months after the Closing Date and shall be effective with respect to any inaccuracy therein or breach thereof, notice of which shall have been duly given within such 12 month period in accordance with Article 5.4 hereof, after which 12-month or the Sublease term, , as the case may be, they shall terminate and be of no further force or effect. Anything to the contrary contained herein notwithstanding, neither party shall be entitled to any recovery from the other party with respect

to any inaccuracy or breach of such warranties or representations unless and until the amount of such Loss suffered, sustained or incurred by the asserting party, or to which such party becomes subject, by reason of such inaccuracy or breach, shall exceed Ten Thousand Dollars ($10,000.00) calculated on a cumulative basis and not a per item basis (the “Basket Amount”), and then only with respect to the excess over the Basket Amount but in no event shall either party be liable to the other in an aggregate amount in excess of Eight Hundred Thousand Dollars ($800,000.00) (the “Cap”). The Basket Amount and the Cap shall not be applicable to claims arising under Article 3.12 (Title to Transferred Assets) or to claims based on fraud, willful misrepresentation or deceit.

5.4 Notice and Opportunity to Defend. If there occurs an event that either party asserts is an indemnifiable event pursuant to Articles 5.1 and 5.2 hereof, the party seeking indemnification (the “Indemnitee”) shall notify the party obligated to provide indemnification (the “Indemnitor”) promptly. If such event involves (i) any claim, or (ii) the commencement of any action or proceeding by a third person, the Indemnitee will give the Indemnitor written notice of such claim or the commencement of such action or proceeding within 15 days of the Indemnitee’s becoming aware thereof; provided, however, that delay or failure to so notify the Indemnitor shall only relieve the Indemnitor of its obligations to the extent, if at all, that it is prejudiced by reasons of such delay or failure. The Indemnitor shall have a period of 30 days within which to respond thereto. If the Indemnitor accepts responsibility within such 30 day period, the Indemnitor shall provide the Indemnitee with such assurances as may be reasonably required by the Indemnitee to assure that the Indemnitor will assume and be responsible for the entire liability at issue, subject to the Cap. The Indemnitee agrees to cooperate fully with the Indemnitor and its counsel in the defense against any such asserted liability. In any event, the Indemnitee shall have the right to participate in a non-controlling manner and at its own expense in the defense of such asserted liability. Any compromise of such asserted liability by the Indemnitor shall require the prior written consent of the Indemnitee, which shall not be withheld unreasonably, and until such consent is obtained, the Indemnitor shall continue defense of such asserted liability. If, however, the Indemnitee refuses its consent to a bona fide offer of settlement that the Indemnitor wishes to accept, the Indemnitee may continue to pursue such matter, free of any participation by the Indemnitor, at the sole expense of the Indemnitee. In such

event, the obligation of the Indemnitor to the Indemnitee shall be equal to the lesser of (y) the amount of the offer of settlement which the Indemnitee refused to accept plus Indemnitee’s Loss, if any, prior to the date the Indemnitor notifies the Indemnitee of the offer of settlement, and (z) the actual out-of-pocket amount the Indemnitee is obligated to pay as a result of the Indemnitee’s continuing to pursue such matter, in each case subject to the Cap. The Indemnitor shall be entitled to recover from the Indemnitee any additional expenses incurred by the Indemnitor as a result of the decision of the Indemnitee to pursue such matter.

5.5 Exclusive Remedy. Except as provided in the Ancillary Agreements, each party hereto agrees that, from and after the Closing, its sole and exclusive remedy at law with respect to any and all claims relating to the subject matter of this Agreement shall be pursuant to the indemnification provisions set forth in this Article 5.

6. Other Agreements and Covenants.

7.4 Waiver of Jury Trial. DMC/SF AND AEROJET HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

No waiver of a provision of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (whether or not similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly therein provided

If any party has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty, or covenant relating to the same subject matter (regardless of the relative levels of specificity) which the party has not breached shall not detract from or mitigate the fact that the party is in breach of the first representation, warranty, or covenant. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction.
