does not make one of such elections within the Option Period, the Selling Party shall have the right to sell its interest to the person or entity who made the Third Party Offer for cash consideration only on terms and conditions no more favorable to such person or entity within sixty (60) days after the expiration of the Option Period. If such sale is not completed within such sixty (60) day period, the offer from the Selling Party shall be deemed to have been revoked and any subsequent offer from such Selling Party shall be subject to the right of first refusal described herein. 12.2. TERMINATION OF THE JOINT VENTURE. (a) If there is an Event of Bankruptcy with respect to either Party, then the other Party may elect either to terminate the Joint Venture (and follow the liquidation procedures set forth in Article 22.3) or to purchase the interest of the Party who had an Event of Bankruptcy for a purchase price equal to the market value of such interest as determined pursuant to subsection (c). Such election shall occur within 60 days after the Event of Bankruptcy unless prohibited by a bankruptcy court or other court of competent jurisdiction; provided that once any such prohibition is no longer applicable, such election shall occur promptly thereafter. The other Party shall provide written notice to the Party who had an Event of Bankruptcy upon the election of the other Party, which notice shall specify the effective date of the action elected by the other Party. (b) If the Parties shall agree to terminate the Joint Venture pursuant to the terms of the Agreement, the Parties agree to terminate the Joint Venture and follow the liquidation procedures set forth in Article 22.3 unless the Parties otherwise agree. (c) Upon delivery by either Party of such Party's election to purchase the interest of the other Party upon the other Party having an Event of Bankruptcy, the Board shall meet for the purpose of retaining a mutually acceptable, qualified investment banking, accounting or appraisal firm of national reputation with no conflict of interest with respect to either Party or any Affiliate thereof (a "Qualified Expert") to determine the market value of the Operating Company. If the Board is unable to select by unanimous agreement a single Qualified Expert, then the appraisal shall be arrived at by mutual agreement of two Qualified Experts, one selected by each Party. If in such an instance either Party shall fail to appoint a Qualified Expert within fifteen (15) days after a written request to do so, such failure shall be deemed acceptance of the conclusions and appraisal of such Qualified Expert as has been appointed. If the Board unanimously selects a single Qualified Expert, the value of the Operating Company as determined by such Qualified Expert shall be final and binding upon both of the Parties. If two Qualified Experts are chosen, one by each Party, and such Qualified Experts either agree or the greater of the two valuations is no more than 110% of the lesser valuation, the average of the valuations of the Operating Company as determined by each such Qualified Expert shall be the value of the Operating Company for the purposes of this Article 12.2 and shall be final and binding upon both Parties. If two Qualified Experts are chosen, one by each Party, and such Qualified Experts cannot agree within thirty (30) days of the appointment of the second of such Qualified Expert (or their valuations differ by more than 10%), then (i) the two appointed Qualified Experts shall select a third Qualified Expert, (ii) if the determination of any of the three Qualified Experts is greater than the two smallest determinations or smaller than the two greatest determinations, in either case by more than 125% of the difference between such other determinations, such determination will be disregarded and the average of the two remaining determinations shall be final and binding upon both of the Parties and (iii) otherwise, the average of the three determinations of the three Qualified Experts shall be final and binding upon both of the Parties. The market value for the interest of the Party who has had an Event of Bankruptcy shall equal the market value of the Operating Company as determined above times the interest of such Party in the Operating Company as stated in Article 4.1. 13. LIABILITIES. 13.1. Igene (the "Indemnifying Party") shall indemnify and hold harmless T&L, its Affiliates, the Operating Company and
