9. Legal Costs. If any party to this Agreement shall take any action to enforce this Agreement or bring any action or commence any arbitration for any relief against any other party, declaratory or otherwise, arising out of this Agreement, the losing party shall pay to the prevailing party a reasonable sum for attorneys’ and experts’ fees and costs incurred in taking such action, bringing such suit and/or enforcing any judgment granted therein, all of which shall be deemed to have accrued upon the commencement of such action and shall be paid whether or not such action is prosecuted to judgment. Any judgment or order entered in such action shall contain a specific provision providing for the recovery of attorneys’ and experts’ fees and costs due hereunder and shall be determined by a court of competent jurisdiction and not by a jury.

10. Brokers. Aerojet and DMC each warrant and represent to the other that it has not retained, nor is it obligated to, any person for brokerage, finder’s or similar services in connection with the transactions contemplated by this Agreement, and that no commission, finder’s fee or other brokerage or agent’s compensation can be properly claimed by any person or entity based upon the acts of such party with regard to the transactions which are the subject matter of this Agreement. Each party shall indemnify, defend and hold harmless the other party against from and against all claims, demands, liabilities, losses, damages, costs and expenses (including, without limitation, reasonable attorneys’ fees, costs of expert witnesses, court costs and other litigation expenses) arising from or related to such party’s breach of the foregoing representation and warranty.

11. Time of the Essence. Time is of the essence of this Agreement. In the event that any date specified in this Agreement falls on Saturday, Sunday or a public holiday on which public agencies and major banks are not open for business (each a “Non-Business Day”), such date shall be deemed to be the succeeding business day. For purposes of this Agreement, the term “business day” shall mean any day other than a Non-Business Day.

12. Binding on Successors. This Agreement shall be binding not only upon the parties but also, subject to the limitations set forth in Section 13, upon their heirs, personal representatives, assigns, and other successors in interest.

13. Assignment. Aerojet may not assign its interests under this Agreement to any other party without the prior written consent of DMC. Notwithstanding the foregoing, DMC agrees that Aerojet may assign its rights to, and delegate its duties and obligations under, this Agreement to an affiliate of Aerojet, at or prior to the Closing without the prior written consent of DMC. For purposes of this Agreement, the term “affiliate” shall mean any partnership, corporation, trust or other entity or association, directly or indirectly, through one or more intermediaries, controlling, controlled by, or under common control with Aerojet. The term “control,” as used in the immediately preceding sentence, means, with respect to a corporation or limited liability company the right to exercise, directly or indirectly, more than fifty percent (50%) of the voting rights attributable to the controlled corporation or limited liability company, and, with respect to any individual, partnership, trust, other entity or association, the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of the controlled entity.

14. Entire Agreement; Modification; Waiver. This Agreement constitutes the entire agreement between Aerojet and DMC pertaining to the subject matter contained in it and supersedes all prior and contemporaneous agreements, representations, and understandings. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by all the parties. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision, whether or not similar, nor shall any waiver constitute a continuing waiver. No waiver shall be binding unless executed in writing by the party making the waiver.

15. Further Assurances. DMC and Aerojet agree to take such additional actions and to execute such additional documents, including escrow instructions, as may be reasonable and necessary to carry out the provisions of this Agreement.

16. Severability. Each provision of this Agreement is severable from any and all other provisions of this Agreement. Should any provision(s) of this Agreement be for any reason unenforceable, the balance shall nonetheless be of full force and effect.

17. Governing Law. This Agreement shall be governed and construed in accordance with the laws of the State of California.

18. Drafting. The parties to this Agreement agree that this Agreement is the product of joint draftsmanship and negotiation and that should any of the terms be determined by a court, or in any type of quasi-judicial or other proceeding, to be vague, ambiguous and/or unintelligible, that the same sentences, phrases, clauses or other wordage or language of any kind shall not be construed against the drafting party in accordance with California Civil Code Section 1654, and that each such party to this Agreement waives the effect of such statute.

19. Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original (including copies sent to a party by facsimile transmission) as against the party signing such counterpart, but which together shall constitute one and the same instrument.
