Right of First Refusal. (a) Right of First Refusal. Purchaser shall not at any time Transfer (as herein defined) all or any part of its Rights unless and until it shall obtain the written consent of Seller, such consent not to be unreasonably withheld or delayed, or it shall comply in full with the requirements of this Section 6. (1) Notice. If Purchaser desires to Transfer all or any part of its Rights, Purchaser shall serve upon Seller written notice (the "First Notice") of its intention to do so. The First Notice shall constitute an offer on the part of Purchaser to sell to Seller all of the Rights owned by Purchaser on the price and other terms therein described. Such offer shall be accepted in whole or rejected by Seller by notice to Purchaser (the "Second Notice") within sixty (60) days of receipt of the First Notice. If such offer of all of the Rights is accepted by Seller, then the closing of the purchase and sale shall be effected as provided for in Section 6. Seller shall not be permitted to purchase less than all of Purchaser's Rights. (2) Right to Offer Rights to Non-Parties. If Purchaser's offer pursuant to the First Notice to sell all of its Rights shall not have been accepted, then, the Purchaser's offer shall be deemed to have been rejected and: A. All restrictions imposed by this Agreement upon the sale of the Rights of Purchaser shall be suspended for a period of four (4) months (the "Suspension Period"), commencing on the earlier of the date of (i) either the mailing of the Second Notice or (ii) sixty (60) days after the mailing of the First Notice during which period Purchaser may sell all of its Rights pursuant to a bona fide arms'-length sale transaction to a third party purchaser (the "Proposed Purchaser") provided that (i) the sale to the Proposed Purchaser is on terms no more favorable to the Proposed Purchaser than those contained in the First Notice; and (ii) Seller does not object to the Proposed Purchaser in accordance with the next sentence. Seller shall have the right to object to the Proposed Purchaser only if Seller has a substantial business reason (which shall include the case wherein a Proposed Purchaser has an interest materially adverse to that of the Company or Seller) (it being agreed by Seller that such standard imposes on Seller a significantly greater burden than a "consent not to be unreasonably withheld" standard). Seller shall advise Purchase promptly of its decision and Seller shall, upon Purchaser's request, advise Purchaser whether it objects to such person prior to Purchaser commencing and/or finishing its negotiations with such person. B. All sales pursuant to a rights sale contract referred to in clause 2(A) immediately above shall be made in accordance with applicable federal and state securities laws and Seller can require Purchaser to furnish to Seller, at Purchaser's expense, an opinion of counsel, reasonably acceptable as to the form, substance and issuer thereof, that such sale is exempt from applicable federal and state securities registration requirements. All Rights sold pursuant to this Subsection 6(a) to a Proposed Purchaser shall continue to be subject to all the terms of this Agreement and as a precondition to the effectiveness of a sale of the Rights, the Proposed Purchaser shall execute a writing to such effect reasonably satisfactory to Seller. C. If, at the conclusion of the Suspension Period Purchaser still owns any Rights all restrictions imposed by this Agreement on the sale of <PAGE 6> Purchaser's Rights shall automatically once again become fully effective and applicable. (3) Closing. The closing of any purchase and sale pursuant to Section 6(a)(1) shall take place at 10:00 a.m. on a date which is not less than thirty (30) and not more than forty-five (45) days after the acceptance in whole of the offer by Seller. (4) "Transfer" shall mean to directly or indirectly give, sell, assign, transfer, pledge, hypothecate, mortgage, create a security interest in, create any other lien on or in any other manner whatsoever encumber or dispose of any record or beneficial ownership of all or any part of the Rights, or the entrance into any contract or other document to do any of the foregoing provided that Transfers shall not include transfers by bequest or intestacy permitted by the next sentence. Notwithstanding the preceding sentence or any other provision herein to the contrary, any permitted transferee of Purchaser which is an individual may bequeath or pass by intestacy his interests in the Rights to any one or more members of his family provided that such transferee(s) continue to be subject to all the terms of this Agreement and as a pre-condition to the effectiveness of such transfer of the Rights, the transferee(s) shall execute a writing to such effect reasonably satisfactory to Seller. Any attempted Transfer not made in accordance with the terms hereof shall be void ab initio. (5) Timing and Amount of Payments. The future purchase price provided for in Section 6(a)(1) shall be paid by Seller to Purchaser by wire transfer of immediately available funds provided that any amount payable under the Note as of such Closing, including any interest accrued as of such date, whether or not then due, shall reduce the amount required to be paid by Seller under this Section 6(a)(5) and any such amounts so offset under the Note shall be extinguished. 7. Survival of Agreements; No Implied Representations. Except as may be expressly provided to the contrary in this Agreement, all of the representations, warranties, covenants or agreements of either party contained herein shall survive the execution, delivery and performance of this Agreement. Seller is making no representation or warranty whatsoever, express or implied, except those express representations and warranties made by Seller in this Agreement. Subject to the foregoing, Purchaser acquires the Purchased Assets "as is" and "where is". Nothing outside of the representations and warranties expressly made by Seller in this Agreement is or shall be deemed to be a representation or warranty of Seller for any purpose whatsoever. 8. Other Agreements. (a) Consent Required for Certain Affiliated Transactions. Seller agrees that it will not enter into, and will not cause or permit any of its affiliates to enter into, any agreements or other arrangements with the Company other than those which are on terms and conditions no less favorable to the Company than terms and condition which could be obtained pursuant to arms'-length negotiations with an independent third party. (b) Tax Sharing Arrangements. Within 30 days after the date hereof the Company and Seller will enter into a tax sharing arrangement which will provide that (i) the Company will pay Seller an amount equal to the share of income, franchise and similar taxes it would be responsible for as a stand alone corporation provided that Seller and the Company may agree that the Company is not obligated to make such payments to Seller and (ii) Seller will pay to the Company an amount which arises from any reduction in any taxes of Seller by reason of any losses that the Company may have. <PAGE 7> The Rights shall apply to all payments by the Company to the Seller pursuant to the tax sharing arrangement. (c) Indemnification and Related Agreements. (i) Each party agrees to indemnify, defend and hold harmless the other party from and against any losses, liabilities, expenses, including reasonable attorneys fees, damages and other costs ("Losses") incurred or suffered arising from or in connection with any of the following actions by such party: (A) any misrepresentation or breach of a warranty by a party in this Agreement; or (B) any breach of a covenant by a party in this Agreement.

(or its subcontractors or suppliers, or its or its subcontractors' or suppliers' affiliates, successors or assigns) (collectively "Hawker Siddeley") related to the design, engineering, procurement or construction of the Company's Facility. Any amounts and other consideration which may be paid to the Company by or on behalf of Hawker Siddeley in connection with the settlement of, judgment on or other disposition the Company's claims in the above-described litigation shall not, whether or not distributed to Seller, be directly or indirectly subject to the Rights and, accordingly, any such amount received by Seller which is paid to the Bank to reduce the loan to the Company shall not directly ar indirectly inure to the benefit of Purchaser, it being understood that a reduction in such loan will increase the proceeds available to the Seller from a sale of OBN Stock. Seller shall advise in writing the Purchaser of the receipt of any such amounts and of the amount of any such assets included in any distribution to Seller (and a statement confirming that Purchaser is not entitled to a portion of such assets pursuant to this Section 8(c)).
