R E C I T A L S 	WHEREAS, Purchaser and Seller are parties to that certain Asset Purchase Agreement, dated as of the date hereof (the "Purchase Agreement"); 	WHEREAS, Purchaser is directly wholly-owned by Parent; 	NOW, THEREFORE, in consideration of the premises and as an inducement for Seller to enter into the Purchase Agreement, the parties hereto agree as follows: Section 1. Definitions. Capitalized terms used herein and not otherwise defined herein shall have the respective meanings given to them in the Purchase Agreement. Section 2. Equity Contribution. (a) Seller may, in its sole discretion and without the concurrence of Purchaser or any of its Affiliates, give written notice to be received by Parent (i) on a date that is six (6) Business Days prior to the Closing Date (the "Notice Date"), which notice shall certify that, as of the Notice Date, the Montana Conditions are satisfied and that, if the Closing were to occur on the Notice Date, Seller would be prepared to satisfy the conditions to Closing that are solely within the control of Seller; and (ii) on a date that is six (6) Business Days prior to the Closing Date under either of the Portland Purchase Agreement or the Puget Purchase Agreement (as the term "Closing Date" is defined under each of those agreements) (an "Additional Notice Date"), which notice shall certify that Seller has been notified by Portland and/or Puget, as applicable that, as of any such Additional Notice Date, the Portland Conditions and/or the Puget Conditions, as applicable, are satisfied and that, if the Closing were to occur on the Notice Date, Portland and/or Puget, as applicable, would be prepared to satisfy the conditions to Closing that are solely within the control of such party. Parent hereby irrevocably promises and agrees that, upon receipt of the notice referred to in clause (i) of the preceding sentence, Parent will make or cause to be made, on the date of the Closing, a contribution in immediately available funds to Purchaser in the amount of the Base Purchase Price, adjusted to take into account additional Excluded Assets, if any, pursuant to Section 1.10 of the Purchase Agreement and that, upon receipt of any notice referred to in clause (ii) of the preceding sentence, Parent will make or cause to be made, on the date of the Closing under the Portland Purchase Agreement or the Puget Purchase Agreement, as applicable, a contribution in immediately available Funds in the amount of the Puget Payment Amount, the Portland Payment Amount or the Combined Payment Amount, as applicable, pursuant to Section 1.05(b) of the Purchase Agreement (the amount required to be contributed by Parent pursuant to each individual notice referred to in clauses (i) and (ii) of the preceding sentence is sometimes hereinafter referred to as the "Required Contribution Amount"). (b) If Purchaser breaches its obligation to effect the Closing as and when required by the Purchase Agreement (or any Closing under the Portland Purchase Agreement or the Puget Purchase Agreement as and when required under such agreements), and, if as a result thereof, Purchaser is the subject of a final and binding order of a court of competent jurisdiction obligating it to pay any damages, costs, and expenses incurred by Seller (a "Liability"), Seller may, in its sole discretion and without the concurrence of Purchaser or any of its Affiliates, give written notice to Parent that such Liability was incurred. Parent irrevocably promises and agrees that it shall make or cause to be made a contribution in immediately available funds to Purchaser within five (5) Business Days after receipt of such notice in an amount sufficient for Purchaser to fully satisfy and discharge the Liability up to but not to exceed the applicable Required Contribution Amount. (c) If a court of competent jurisdiction enters a final and binding order to the effect that Seller was not entitled to give any notice provided for in subsection (a) or (b) hereof, then Seller shall be liable to pay Parent, as liquidated damages and in full satisfaction of any claim of Purchaser or any of its Affiliates arising out of such notice or order insofar as such order relates to Seller giving such notice, an amount equal to the documented out-of-pocket costs of Parent (including, without limitation, Parent's cost of capital after giving effect to related income taxes) incurred in connection with Parent's contribution (or arrangements made to cause such contribution) to Purchaser as a result of such wrongful notice by Seller. (d) Notwithstanding any other provision of this Agreement to the contrary, Parent shall have no obligation to make or cause to be made any contribution to Purchaser under this Agreement to the extent its aggregate contributions to Purchaser made or cause to be made as a result of a notice given by Seller hereunder or otherwise contributed (provided such funds have been segregated in accordance with Section 4 hereunder or are otherwise available for payment by Purchaser of the Purchase Price under the Purchase Agreement) equal or exceed the aggregate of the Required Contribution Amounts. (e) Any payments made or cause to be made by Parent directly to Seller in satisfaction of Parent's obligations to make or cause to be made a contribution to Purchaser hereunder shall be deemed to be on behalf of, and to satisfy the obligations of, Purchaser to Seller under the Purchase Agreement (to the extent of the amount paid or caused to be paid by Parent). (f) If, prior to receipt of a notice from Seller requesting a contribution to Purchaser, Parent makes or causes to be made a contribution to Purchaser as contemplated herein, it shall promptly notify Seller in writing of such contribution, which notice shall state that such contribution has been segregated as provided in Section 4 herein. (g) Upon written request of Seller given to Purchaser at any time after Parent has made or caused to be made a contribution to Purchaser contemplated herein, Purchaser agrees to return such contribution to Parent. (h) If, following the making by Parent of a Required Contribution Amount hereunder, the Closing in respect of which such contribution was made fails to occur as scheduled (other than any such failure caused solely by a breach by Purchaser of its obligation to effect such Closing), any Funds so contributed to Purchaser may be returned to Parent; provided, that this Agreement shall continue in effect until termination in accordance with the provisions of Section 5 hereof.
