Terms and Conditions for Technical Services Agreement

ARTICLE I. Scope of Technical Services. Subject to the following terms and conditions, Alliance for Sustainable Energy, LLC (herein also “Contractor” or “NREL”) agrees to provide Technical Services to the Sponsor in the defined work areas identified in the Scope of Work attached and incorporated herein. It is understood by the Parties that, except for the intellectual property provisions of this Agreement, Contractor is obligated to comply with the terms and conditions of the Department of Energy (herein also “DOE” or “Government”) M&O Contract when providing goods, services, products, processes, materials, or information to the Sponsor under this Agreement. The Parties understand that DOE has authorized the Contractor to use this Technical Services Agreement when appropriate and that the total cost to Sponsor will not exceed $500,000.

ARTICLE II. Term and Termination of Agreement. The Contractor’s estimated period of performance for completion of the Scope of Work is the term of this Agreement. The term shall be effective as the later date of (1) the date on which this Agreement is signed by the last of the Parties thereto, or (2) the date on which the Contractor receives advance payment from the Sponsor and funds are allocated to this Agreement. This Agreement may be terminated, in whole or in any part, at any time by either Party, without liability, upon giving ten (10) days written notice to the other Party. In the event of termination, the Sponsor shall be responsible for the Contractor’s costs (including closeout costs) through the effective date of termination, but in no event shall the Sponsor’s cost responsibility exceed the total cost to the Sponsor as described in the Scope of Work.

ARTICLE III. Costs. The Contractor has no obligation to continue or complete performance of the work at a cost in excess of its estimated cost. The Contractor agrees to provide at least thirty (30) days written notice to the Sponsor if the actual cost to complete performance will exceed Contractor’s estimated cost.

ARTICLE IV. Funding and Payment. This Technical Services Agreement is based on full cost recovery and the Contractor is required by the Government to receive advance funding before beginning work. The Sponsor shall provide sufficient funds in advance to reimburse the Contractor for costs to be incurred in performance of the work described in this Agreement, and the Contractor shall have no obligation to perform in the absence of adequate advance funds. If the estimated period of performance exceeds 90 days and the estimated cost exceeds $25,000, the Sponsor may, with the Contractor’s approval, advance funds incrementally. In such a case, the Sponsor shall provide to the Contractor, prior to any work being performed, an advance payment sufficient to cover anticipated work that will be performed for the first billing cycle. In addition, the Sponsor shall provide additional funding to ensure that funds remain available for work during subsequent billing cycles (collectively the advance payment of $23,000.00 as set forth in Block II (h) of the attached cover page for this Agreement). Following Sponsor’s remittance of the advance payment, the Contractor will invoice the Sponsor each billing cycle (or as necessary) to maintain a balance of funding sufficient to cover anticipated work. Sponsor’s payment shall be due no later than thirty (30) days after receipt of Contractor’s invoice. Upon termination or completion, any excess funds shall be refunded by the Contractor to the Sponsor.

Sponsor shall enter this Agreement number on the check made payable to the Alliance for Sustainable Energy, LLC and mail payment to the following address:

Article VI. Tangible Personal Property. Upon termination of this Agreement, tangible personal property or equipment produced or acquired in conducting work under this Agreement shall be owned by the Sponsor.
