        Identification of Pond Project.
 2.2.1BTI shall notify PinnOak within thirty (30) days after a Beard Entity identifies a Pond Project with respect to which it intends to participate. 2.2.2Promptly after PinnOaks receipt of that notification, BTI and PinnOak shall schedule a meeting to be held at BTIs principal place of business in  Pittsburgh, Pennsylvania, or at such other location agreed upon by the Parties (the Initial Project Meeting), at which BTI shall provide PinnOak with a detailed and comprehensive presentation and evaluation of the proposed Pond Project (a Project Proposal), which shall include (i) the equity funding levels and concomitant percentages of equity ownership available to PinnOak, as determined in accordance with the provisions of Section 2.3, in a limited liability company to be formed by the Beard Entity to develop the proposed Pond Project (the Project LLC), (ii) BTIs estimates of the commercially marketable coal
reserves, the cost of development, the probable net profits, and the timing of developmental activities attributable to the proposed Pond Project, and (iii) a date by which the equity funding must be made. 2.2.3Prior to the Initial Project Meeting, PinnOak shall sign and provide BTI with a legally binding and enforceable non-disclosure and non-compete agreement, which shall be in a form and substance reasonably acceptable to BTI and PinnOak, covering the Project Proposal and the proposed Pond Project. 2.2.4PinnOak shall have thirty (30) days after the Initial Project Meeting to provide BTI with their affirmative written election to accept in all material respects the Project Proposal made at the Initial Project Meeting.  If PinnOak does not provide BTI with that affirmative election before the expiration of that 30-day period, PinnOak shall be conclusively deemed to have rejected that Project Proposal. 2.2.5BTI shall promptly and comprehensively respond to all reasonable inquiries from PinnOak concerning the Project Proposal during that 30-day period. 2.2.6If PinnOak accepts a Project Proposal in accordance with Subsection 2.2.4 (an Accepted Pond Project), PinnOak shall be obligated to participate in the Accepted Pond Project in accordance with the terms provided for that Accepted Pond Project in the Initial Project Meeting, as may be or have been modified in writing by agreement of the Parties.  5    2.2.7PinnOaks involvement and participation in each Accepted Pond Project shall be (i) limited to its becoming an equity owner together with BTI and/or one or more other Beard Entities in the Project LLC formed by BTI for that Accepted Pond Project and (ii) subject to the terms of an operating agreement for that Project LLC having substantially the same terms as the BP Operating Agreement, except conforming to the allocation of annual net cash flow as determined in accordance with this Agreement for that Project LLC, and except for such other exceptions agreed upon in writing by the Parties.  Under no circumstances shall PinnOaks participation and involvement in any Accepted Pond Project be as a cotenant or sublessee.  Notwithstanding the allocation of Annual Net Cash Flow for any Project LLC, as
determined in accordance with this Agreement, the Beard Entities shall own not less than fifty percent (50%) of the aggregate equity ownership or membership interest in each Project LLC, unless one or more of the Beard Entities assign a portion of such membership interest to an Unrelated Third Person, including, without limitation, a Third Party Owner or its affiliate with respect to a Third Party Pond Project. 2.2.8Each Project LLC and BTI shall enter into a pond fines recovery facility agreement having terms similar to those contained in the Pond Fines Agreement, but which shall be expressly tailored for the Accepted Pond Project.  BTI and each Project LLC shall enter into a contract operating agreement designating BTI as the contract operator of that Accepted Pond Project.

        Equity Participation; Distributions of Annual Net Cash Flow.
 The management of each Project LLC formed for an Accepted Pond Project shall be provided and set forth in the Project LLCs operating agreement the terms and conditions of which shall be the same in all material respects as the BP Operating Agreement.  The allocation of each Project LLCs distribution of Annual Net Cash Flow, if any, among its owners shall be determined in accordance with this Section 2.3.  2.3.1
        Unfunded Projects.
  (a)If PinnOak exercises the Preferential Right to participate in any Unfunded Project LLC (i.e., a Project LLC formed for an Accepted Pond Project for which a Beard Entity needs 100% of the equity funding required for that Project LLC to qualify for a Guaranteed Third-Party Loan), then PinnOak shall contribute all the equity funding necessary for that  6    Unfunded Project LLC to qualify for a Guaranteed Third-Party Loan in accordance with the equity funding schedule provided for in the Project Proposal for that Unfunded Project LLC. (b)Upon an Unfunded Project LLCs receipt of the equity funding provided for in Subsection 2.3.1 (a) from PinnOak, the Unfunded Project LLC shall issue an equity or membership interest in that Unfunded Project LLC to PinnOak up to a maximum of 50% of the aggregate membership interests.  One or more of the Beard Entities shall own the remaining equity or membership interest in that Unfunded Project LLC. (c)The management and operation of each Unfunded Project LLC shall be governed by an operating agreement signed by the members thereof, which shall be the same in all material respects as the BP Operating Agreement except that BTI shall own fifty percent (50%) of the membership interests in such Unfunded Project LLC. (d)The distribution of Annual Net Cash Flow, if any, generated by an Unfunded Project LLC shall be as follows: Annual Net Cash Flow
        Beards Distributive Share

        50.00%
  (e)If PinnOak exercises the Preferential Right to acquire less than fifty percent (50%) of all the equity or membership interest in an Unfunded Project LLC, then PinnOaks percentage distributive share of Annual Net Cash Flow from that Unfunded Project LLC shall be equal to the result obtained by multiplying each corresponding PinnOaks Distributive Share percentage, as set forth in the chart in Subsection 2.3.1(d), by a fraction, the numerator of which is the percentage equity ownership in the Project LLC acquired by PinnOak and the denominator of which is fifty percent (50%). 2.3.2
        Fully Funded Project.
 (a)With respect to any Pond Project for which one or more Beard Entities has provided one hundred percent (100%) of the equity funding (whether by one or more capital contributions consisting of cash, cash equivalents and/or other personal property, such as equipment) required by the Project LLC formed for that Accepted Pond Project to qualify for a Guaranteed Third-Party Loan (a Fully Funded Project LLC), PinnOak shall be entitled to exercise the Preferential Right to purchase up to, but not more than fifty percent (50%) of all the equity ownership in that Fully Funded Project LLC from the Beard Entities owning it for a purchase price equal to the result obtained by multiplying the sum of the amount of cash and cash equivalents contributed by the Beard Entities plus the fair
market value of any equipment contributed by the Beard Entities as of the date of the closing of that sale to PinnOak by the percentage equity ownership which PinnOak elected to acquire in that Fully Funded Project LLC.  Each Fully Funded Project LLC shall be governed by an operating agreement signed by  7    the members thereof, which shall be the same in all material respects as the BP Operating Agreement provided, that the voting rights of members shall reflect the membership interests of the members.  (b)If PinnOak exercises the Preferential Right to acquire fifty percent (50%) of all the equity or membership interest in a Fully Funded Project LLC, then the Parties shall be entitled to the following percentage distributive shares of Annual Net Cash Flow, if any, from that Fully Funded Project LLC: Annual

  (c)If PinnOak elects to acquire less than fifty percent (50%) of all equity or membership interest in a Fully Funded Project LLC, then PinnOaks percentage distributive share of Annual Net Cash Flow for each annual period from that Fully Funded Project LLC shall be equal to the result obtained by multiplying each corresponding PinnOaks Distributive Share percentage, as set forth in the chart in Subsection 2.3.2(b), by a fraction, the numerator of which is the percentage equity ownership in the Project LLC acquired by PinnOak and the denominator of which is fifty percent (50%). 2.3.3
        Partially Funded Projects.
 (a)With respect to any Pond Project for which a Beard Entity is providing some but less than one hundred percent (100%) of all the equity funding required for the Project LLC formed for that Pond Project (a Partially Funded Project LLC) to qualify for a Guaranteed Third-Party Loan, PinnOak may exercise the Preferential Right to fund the remaining equity capital necessary for the Partially Funded Project LLC to qualify for that loan, subject to the terms provided in Section 2.4.  In such event, the equity or membership interest to be issued to PinnOak in the Partially Funded Project LLC shall be an amount equal to fifty percent (50%) multiplied by a fraction, the numerator of which is the total equity or capital contribution made by PinnOak and the denominator of which is the sum
of all equity or capital contributions made by all of the Parties.  Each Partially Funded Project LLC shall be governed by an operating agreement signed by the members thereof which shall be the same in all material respects as the BP Operating Agreement provided, that the voting rights of members shall reflect the membership interest of the members. (b)PinnOaks percentage distributive shares of Annual Net Cash Flow from a Partially Funded Project LLC shall be determined by multiplying each corresponding percentage distributive share of Annual Net Cash Flow set forth in the chart in Subsection 2.3.1(d) for  8    PinnOak by a fraction, the numerator of which is the percentage equity ownership in the Project LLC acquired by PinnOak and the denominator of which is fifty percent (50%). (c)If PinnOak exercises the Preferential Right to fund the remaining equity capital necessary for a Partially Funded Project LLC to qualify for a Third-Party Guaranteed Loan, then the Beard Entitys percentage distributive percentage shares of Annual Net Cash Flow from that Partially Funded Project LLC shall be determined by subtracting each corresponding percentage distributive share of Annual Net Cash Flow of PinnOak for that Partially Funded Project LLC from one hundred percent (100%). 2.3.4Non Guaranteed Projects.  If a Project Proposal provides for one hundred percent (100%) of the funding of a Project LLCs pond recovery operations from a loan, which is not a Guaranteed Third-Party Loan, then PinnOak may exercise the Preferential Right to acquire up to a thirty percent (30%) equity ownership interest in that Project LLC.  PinnOaks percentage distributive share of Annual Net Cash Flow from that Project LLC shall be equal to the result obtained by multiplying each corresponding PinnOaks Distributive Share percentage, as set forth in the chart in Section 2.3.2(b), by a fraction, the numerator of which is the percentage equity ownership in the Project LLC acquired by PinnOak from the Beard Entities and the denominator of which is fifty
percent (50%).  The management and operation of each non-guaranteed project LLC shall be governed by an operating agreement signed by the members thereof, which shall be the same in all material respects as the BP Operating Agreement provided that the voting rights of members shall reflect the membership interests of the members. 2.4
        Third Party Projects.
 2.4.1Each Beard Entity involved in any negotiations or discussions concerning any prospective Third Party Pond Project shall use its good faith efforts (fairly taking into consideration PinnOaks rights by virtue of the Preferential Right) to obtain a commercially reasonable and feasible agreement or arrangement with each Third Party Owner of the pond site for that Pond Project. 2.4.2Notwithstanding anything to the contrary in Section 2.1, 2.2 or 2.3, the Prospect Proposal for any Third Party Pond Project shall provide PinnOak with the option to acquire by virtue of the Preferential Right no less than fifty percent (50%) of the Beard Entities cumulative equity or membership interest of the Project LLC formed for that Third Party Pond Project. 2.4.3If PinnOak exercises the Preferential Right to acquire an ownership interest in a Project LLC formed for a Third Party Pond Project, the distribution of cumulative Annual Net Cash Flow attributable to PinnOaks ownership in that Project LLC shall be made as provided for in Section 2.3.1(d) except that each PinnOaks Distributive Share percentage set forth in the chart in Section 2.3.1(d) shall be replaced by the result obtained by multiplying that PinnOak Distributive Share percentage by a fraction, the numerator of which is the percentage ownership in that Project LLC acquired by PinnOak and the denominator of which is one hundred percent (100%).  9    2.4.4If there is any direct conflict between, or any ambiguity or uncertainty resulting from the construction of, any provision in this Section 2.4 and any provision in Section 2.1, 2.2 and/or 2.3 or (ii) any disagreement between the Parties concerning the distribution of Annual Net Cash Flow from a Project LLC, the Parties shall use their good faith, reasonable efforts to resolve the ambiguity, uncertainty or conflict by reference to the attachments to the Pond Fines Agreement titled Terms of Equity Financing by PinnOak for the Pinnacle Project and the PinnOak Preferential Right to Purchase.
