Company shall be shared by the Parties in equal shares as long as each Party has a 50% interest in the Operating Company. Upon a reduction or increase in such interest, all profits and losses shall be shared in accordance with each Party's ownership interest in the Joint Venture. To the greatest extent permitted by applicable law and accounting provisions, (a) the Operating Company shall make distributions, dividends and returns of capital equally to each of the Parties and (b) Operating Company items of income, gain, loss and deduction shall be allocated equally to each of the Parties; provided, if for any reason, such distributions, dividends, returns of capital or allocations may not be made on an equal basis, the Operating Company shall make a special distribution, dividend, return of capital or allocation to one Party to balance the required distribution, dividend, return of capital or allocation to the other Party. 4.3. Notwithstanding the foregoing, if for any reason the contribution of* T&L proves to have a value materially less than that attributed to it at the Effective Date as a result of the Facilities not being constructed as provided herein then either (a) T&L shall contribute a cash amount to the Operating Company to make up the shortfall or (b)(i) T&L's capital account shall be adjusted to reflect the revaluation of its contribution, (ii) T&L's interest in the Operating Company shall be adjusted to reflect its actual proportion of the contributions made upon the formation of the Joint Venture and (iii) the Joint Venture shall be liquidated as provided in Article 22.3. * Portions intentionally deleted pursuant to a request for confidential treatment. 5. [INTENTIONALLY OMITTED] 6. TAX CONSIDERATIONS. 6.1. Each Party shall produce and submit to the Board, as promptly as possible, a reasonable estimate of their respective income tax liability with respect to the income of the Operating Company computed pursuant to the provisions of this paragraph as by a reasonably prudent taxpayer attempting to reduce the income tax payable by such taxpayer to the greatest extent permitted by law (a "Party Tax Estimate"). A Party Tax Estimate shall be calculated pursuant to United States and/or United Kingdom law and regulations (and the laws and regulations of any other jurisdiction under which the earnings of the Operating Company may be taxable to either Party) as may be applicable to either Party. The tax liability shall be calculated based on each Party's share of the income, gain, costs, expenses and deductions of the Operating Company in the prior year without consideration of items of income, gain, loss or deduction applicable to either Party derived from outside the Operating Company (including, without limitation, with respect to Igene, any Net Operating Loss that Igene may have accumulated prior to the formation of the Joint Venture), but shall include any items of income, gain, loss or deduction derived from the Operating Company in any previous year to the extent applicable to such year. Such Party Tax Estimate shall not be deemed to be final until it is approved by the Board; provided, that if the Board does not approve the higher Tax Estimate, and cannot resolve such a dispute within thirty days of the submission of such Tax Estimate to the Board, then the lesser Tax Estimate (the "Preliminary Minimum Distribution") shall be paid to both Parties pursuant to Article 6.2 as if it were the Minimum Distribution. After the expiration of such thirty day period, the Board shall promptly submit the higher Tax Estimate (the "Disputed Estimate") to PricewaterhouseCoopers (the "Neutral Auditor") who shall evaluate the reasonableness and accuracy of the Disputed Estimate in light of the provisions of this Article 6.1. The Party that submitted the Disputed Estimate shall promptly provide to the Neutral Auditor all information requested by the Neutral Auditor in order to perform the analysis required by this Article 6.1. Within thirty days of receiving all information it deems necessary to perform the analysis required herein, the Neutral Auditor shall inform the Board in writing that it either agrees or disagrees that the Disputed Estimate is reasonable and accurate in light of the provisions of this Article 6.1 and the tax information submitted to it. If the Neutral Auditor concludes that the Disputed Estimate is reasonable and accurate, the difference between the Disputed Estimate and the Preliminary Minimum Distribution shall be promptly paid to each Party. If the Neutral Auditor concludes that the Disputed Estimate is not reasonable and/or accurate then the Preliminary Minimum Distribution shall
