(g) Requirements Applicable to All Dispositions and Admissions. Any Disposition of any Membership Interest, including a Permitted Disposition, and any admission of an Assignee as a Member shall be subject to the following requirements, and such Disposition (and admission, if applicable) shall not be effective unless such requirements are complied with; provided, however, that the non-Disposing Members, in their sole and absolute discretion, may waive any of the following requirements:

The Membership Interests governed by this Agreement have not been registered with the Securities and Exchange Commission under the Securities Act of 1933, as amended, or the state securities laws of Delaware or any other state. Without such registration, no Member may effect or suffer to occur a Disposition of all or any part of its Membership Interest (other than to an Affiliate provided such transfer does not violate any applicable securities laws) without delivery to the Non-Disposing Members of an opinion of counsel (“Securities Law Opinion”) satisfactory to the Non-Disposing Members that such registration is not required for such transfer and/or submission to the Non-Disposing Members of such other evidence as may be reasonably satisfactory to the Non-Disposing Members to the effect that any transfer will not be in violation of the Securities Act of 1933, as amended, applicable state securities laws, or any rule or regulation promulgated thereunder.

(h) The value of any Capital Contributions of property after the Effective Date or other than cash shall be as agreed by the Members holding at least 70% of the Membership Interests.

4.03 Failure to Contribute. If any Member fails to make or fund a Capital Contribution required pursuant to Section 4.01 or Section 4.02 (each, a “Non-Contributing Member”), and if such failure continues for more than ten (10) Days after the date on which it is due, any Member that has contributed its Capital Contributions (each, a “Contributing Member”) may (without limitation as to other remedies that may be available) elect to deliver a notice (a “Notice of Default”) to the Non-Contributing Member. Upon delivery of such Notice of Default: (i) the Non-Contributing Member shall lose all voting rights and all management approval rights under this Agreement, and (ii) all Representatives of the Non-Contributing Member shall be removed from the Management Committee; provided that no Member shall be entitled to any such ten-Day grace period for more than three failures to make or fund such a Capital Contribution.

(b) In addition, after the expiry of all grace periods applicable under Section 4.03(a) such Non-Contributing Member has not cured such default (a “Defaulting Non-Contributing Member”) , the Contributing Member may elect (but is under no obligation) to make an advance to the Company, acting as lender (the “Lending Member,”), equal to the portion of the Defaulting Non-Contributing Member’s Capital Contribution that is in default to the Company, with the following results:

(i) the sum advanced is deemed to be a loan from the Lending Member to the Defaulting Non-Contributing Member;

(ii) the Capital Account of the Defaulting Non-Contributing Member is increased by the amount of the deemed loan from the Lending Member;

(iii) the principal balance of the loan and all accrued unpaid interest thereon is due and payable in whole on the tenth (10th) Day after written demand therefor by the Lending Member to the Defaulting Non-Contributing Member;

(iv) the amount lent bears interest at the Default Rate from the Day that the advance is deemed made until but excluding the date that the loan, together with all interest accrued on it, is repaid to the Lending Member;

(v) all distributions from the Company that otherwise would be made to any Defaulting Non-Contributing Member (whether before or after dissolution of the Company) instead shall be paid to the Lending Member until the loan and all interest accrued on it have been paid in full to the Lending Member (with payments being applied first to accrued and unpaid interest and then to principal) and any such payment to the Lending Member pursuant to this Section 4.03(b)(v) shall be deemed for all purposes as if the cash had first been distributed to the Defaulting Non-Contributing Member, who then paid such cash to the Lending Member as a payment on the loan;

Limited Liability Company Agreement of

DeWind SWI Wind Farms, LLC

(vi) the payment of the loan and interest accrued on it is secured by a security interest in each Defaulting Non-Contributing Member’s Membership Interest, as more fully set forth in Section 4.03(g); and

(vii) the Lending Member may, in addition to the other rights and remedies granted pursuant to this Agreement or available at Law or in equity, take any action (including court proceedings) that such Lending Member may deem appropriate to obtain payment by the Defaulting Non-Contributing Member of the loan and all accrued and unpaid interest on it, at the cost and expense of the Non-Contributing Member.

(c) In addition to the remedies set forth in Sections 4.03(a) and 4.03(b), if the Defaulting Non-Contributing Member has not cured its breach within twenty (20) days after the date on which the Capital Contribution was to be made (a “Default”), then the Company (acting through the Representatives appointed by such Contributing Member) shall issue a notice of the Defaulting Non-Contributing Member’s Default to all Members in the form attached hereto as Exhibit F (a “Default Notice”). Such Contributing Member shall have the option (but no obligation) to have any contribution made pursuant to Section 4.03(b) treated as a permanent Capital Contribution by the Contributing Member (and a reduction in the Capital Account of the Non-Contributing Member to the extent such Member’s Capital Account was increased pursuant to Section 4.03(b)(ii)), or, if no such contribution was made pursuant to Section 4.03(b), pay its pro rata share of the portion of the Capital Contribution owed and unpaid by the Defaulting Non-Contributing Member and such contribution shall be treated as a Capital Contribution by the Contributing Member (either contribution the “Defaulted Contribution”). In either event, the Contributing Members that elect to fund the Defaulting Non-Contributing Member’s share (the “Performing Contribution Members”) shall provide written notice of such election to all Members and upon making such Defaulted Contribution, the Defaulted Contribution of each such Performing Contribution Member shall be treated as a Capital Contribution, and the Members’ Voting Ratios and Sharing Ratios will be automatically adjusted in accordance with the following terms:

(i) the Voting Ratio and Sharing Ratio of each Performing Contribution Member shall, when expressed as a percentage, equal the sum of (i) the sum of (A) an amount equal to the aggregate Capital Contributions previously made by such Performing Contribution Member, excluding the Defaulted Contribution, reduced by the amount, if any, previously distributed to such Performing Contribution Member pursuant to Section 4.01(e), and (B) an amount equal to two hundred percent (200%) of the Defaulted Contribution made by such Performing Contribution Member, divided by (ii) the sum of (A) an amount equal to the aggregate Capital Contributions previously made by all of the Members, excluding all Defaulted Contributions, reduced by the amount previously distributed pursuant to Section 4.01(e), and (B) an amount equal to two hundred percent of the Defaulted Contributions made by all of the Members, and

Limited Liability Company Agreement of

DeWind SWI Wind Farms, LLC

(ii) The Voting Ratio and Sharing Ratio of the Non-Contributing Member shall, when expressed as a percentage, be reduced by an amount equal to the percentage increase in the Voting Ratio and Sharing Ratio, respectively, of the Performing Contribution Member that elected to fund such Non-Contributing Member’s share of the Defaulted Contribution, as calculated pursuant to Section 4.03(c)(i).

(d) If the Non-Contributing Member’s failure to make its Capital Contribution has not been cured within thirty (30) Days from the date of the Non-Contributing Member’s Default and if the Contributing Member notifies the Non-Contributing Member that the Contributing Member will not elect the remedies set forth in Section 4.03(c) or otherwise fails to make such election within the required time period for making such election, and does not elect to loan such Capital Contribution to the Non-Contribution Member pursuant to Section 4.03(b), then the Contributing Member shall have the right (but not the obligation) to dissolve the Company by issuing a dissolution notice to the Non-Contributing Member. Such dissolution notice may be given, and shall be effective upon delivery, when given at any time after the thirty (30) Days cure period set forth above.

(e) The terms of this Section 4.03 seek to induce the Members to pay their respective Capital Contributions.

(f) The remedies set forth in this Section 4.03 shall be the exclusive remedies available under applicable Law for a Member’s non-payment of its Capital Contributions.

(g) Except to the extent prohibited by a lender under the Financing Documents, each Member which is required pursuant to this Agreement to make Capital Contributions hereby grants to the Company, and to each Lending Member with respect to any loans made by the Lending Member to that Member as a Non-Contributing Member pursuant to Section 4.03(b), as security, equally and ratably, for the payment of all Capital Contributions that such Member has agreed to make and the payment of all loans and interest accrued thereon made by Lending Members to that Member as a Non-Contributing Member pursuant to Section 4.03(b), a security interest in and a general lien upon its Membership Interest and the proceeds thereof, all under the Uniform Commercial Code of the State of Delaware.
