Budget Period 1 is divided into two funding periods. DOE will accept title to DUF6 for the initial period (6/1/12-7/31/12) after award of this Agreement to allow the Recipient to begin work on approved activities. Upon satisfying the conditions set forth in this Article 8.01 below, the Contracting Officer will issue written authorization allowing the Recipient to incur costs during the remainder of Budget Period 1 and DOE shall assume the remainder of the DUF6 liability to be assumed for Budget Period 1. As of the execution date of Amendment No. 001, the Parties acknowledge and agree that the Contracting Officer issued the necessary written authorization required by the preceding sentence on 7/31/12. DOE cost share for Budget Period 1 will be fulfilled through DOE’s assuming title and liability for up to 39,200 MT of Depleted Uranium Hexafluoride (DUF6), which the parties agree will be treated as the Government providing $87,670,184 in cost share contributions (80% of the total estimated cost of the agreement for Budget Period 1).

Among other requirements set forth elsewhere in this Agreement, DOE will not assume liability from the Recipient incurred beyond 7/31/12 unless (a) the Equipment Contract (Contract No. DE-NE0000488) has been executed and title to the Transferred Property (as defined therein) has been transferred to DOE and (b) the Recipient provides a revised application for financial assistance under this award to DOE no later than 7/24/12 that includes: (1) cost, schedule, Performance Indicator/Milestone detailed estimate (to Work Breakdown Structure level 3) for the Project; (2) a report detailing ACD’s efforts to implement a governance structure demonstrating capability to provide overall management of the project (see Article 6.02) and demonstrating that the ACD has submitted to the Nuclear Regulatory Commission (NRC) a complete package requesting a Foreign Ownership, Control or Influence (FOCI) determination in a form acceptable to the NRC; and (3) a revised Attachment B that includes proposed Technical Milestone dates. As of the execution date of Amendment No. 001, the Parties acknowledge and agree that Recipient has met the requirement in the preceding sentence.

DOE will not issue written authorization permitting incurrence of costs under this Agreement during Budget Period 2 unless the Recipient submits the following to DOE no later than 9/21/12: (1) documentation evidencing the existence of ACD with, subject to obtaining necessary regulatory approvals, the governance structure referenced in Article 6.02; and (2) revised cost, schedule, Performance Indicator/Milestone detailed estimate (to Work Breakdown Structure level 3) for the American Centrifuge Cascade Demonstration Test Program. Execution of this Amendment No. 001 acknowledges that the requirements of the preceding sentence have been met and written authorization to incur costs under this Agreement during Budget Period 2 was provided by the Contracting Officer.

Budget Period 2 is divided into multiple funding periods. For Budget Period 2, Funding Period 1, DOE has provided up to $45,720,000 for the Government Cost Share. For Budget Period 2, Funding Period 2 (3/13/13-6/15/13), DOE will provide $44,378,055 in Government Cost Share (80% of the total estimated cost of the agreement for Budget Period 2, Funding Period 2). This Cost Share will be met via the agreed upon value of the SWU Component (***** SWU) of the EUP transferred to USEC Inc. in accordance with the provisions of Attachment H.

At DOE’s discretion, and subject to requirements elsewhere in this agreement and the availability of appropriations or other sources of consideration, DOE may provide funding for future funding periods through further amendment(s) of this Agreement. DOE will not authorize continuation of the Project or provide Cost Share funding to reimburse costs incurred by the Recipient under this Agreement for future funding periods unless the Recipient has successfully met all milestones and provided to DOE all deliverables scheduled for performance or delivery before the end of Budget Period 2 Funding Period 2 as set forth in Attachment B Project Scope – Amendment #2 and demonstrates to DOE’s satisfaction evidence of sufficient progress toward Recipient’s ability to successfully meet the milestones scheduled to be completed during future funding periods. In the event DOE provides Additional Funding (above the “Current Funding” provided by Amendment NO. 003 to this Agreement), DOE and Recipient shall amend this Agreement to reflect such Additional Funding.

DOE will not assume liability or otherwise reimburse costs incurred by the Recipient under this Agreement above the Current Funding without first issuing written authorization permitting the Recipient to incur costs under this Agreement above the Current Funding. Notwithstanding the above, there is no requirement for written authorization permitting the Recipient to incur costs under this Agreement constituting the Government Cost Share up to the Total Government Funds Obligated.

In addition to other available remedies, in the event the conditions in this Section 8.01 for the continued funding of the program are not met, the Contracting Officer may suspend or terminate this award without recourse through corrective action by Recipient. In the case of such a suspension or termination, costs shall be addressed as set forth in 10 CFR § 600.24.

7.	Section 9.03 of the Agreement shall be deleted in its entirety and replaced with the following:

9.03 Repayment in the Event of Termination

A. Repayment of Unexpended Funds. In the event the total allowable costs incurred for the project are less than the total estimated project cost through Budget Period 2 Funding Period 2, either due to termination of this Agreement or for other reasons, the total amount of Government Cost Share made under Article 8 will be adjusted on a pro rata basis to equal DOE’s share of the total project costs in the same method in which the Government Cost Share was originally provided (see the table in Section 8.01). For example, unexpended Government Cost Share provided to fund Budget Period 1 Funding Period 1 would be adjusted in the form of DOE’s transferring DUF6 back to USEC. If the overpayment of Government Cost Share cannot be adjusted in the original method in which it was provided, it shall be adjusted via one or more of the following methods, listed in descending order of acceptance:

1) Recipient shall return a quantity of EUP involved in the EUP Transfer equivalent to the proportion of unspent Government Cost Share to DOE and DOE shall, if permissible, consistent with all applicable laws, return the equivalent quantity of Feed Material pro rata based on the agreed value to the nearest full cylinder;

2) In the event either Recipient or DOE cannot effect the transfers in 9.03(A)(1) to fully satisfy the required repayment, Recipient shall repay DOE in funds for any unexpended Government Cost Share; or

3) In the event Recipient or DOE cannot effect either of the prior methods of repayment to fully satisfy the required repayment, as a last option, DOE shall return a pro rata amount of DUF6 to USEC calculated based on the ratio of DUF6 to Government Cost Share originally provided in Budget Period 1 Funding Period to the nearest full cylinder.

B. Accounting and Calculation Procedures. Following termination or expiration of this Agreement, Recipient must submit an accounting of costs incurred until the point of termination or expiration to DOE’s Contracting Officer within ninety (90) days of the date of termination or expiration. Within thirty (30) days of the delivery of the accounting of the total costs of the project, DOE shall notify the Recipient of the need to adjust the Government Cost Share in one of the forms set forth in section 9.03(A), and identify the specific quantity and method of unexpended or unallowed Government Cost Share that must be returned, if applicable. The Recipient will notify DOE of any objection to the amount or method of Government Cost Share return identified under this Section within ten (10) days of receiving DOE’s notice. If adjustment is to be in EUP and there is no objection, the Recipient will identify the cylinder(s) containing the quantity to be returned, or as close to the necessary quantity as reasonably practical. If adjustment requires physical delivery of Feed Material or DUF6 by DOE, DOE will identify the cylinder(s) containing the quantity to be returned, or as close to the necessary quantity as reasonably practical. Recipient or DOE, as appropriate, shall transfer and DOE or Recipient, as appropriate, shall accept title to material required to be transferred under this Section 9.03 on the earlier of (i) the eleventh day after receipt of notice if no objection is delivered; (ii) the date DOE and the Recipient agree to the transfer(s); or (iii) the date any dispute is resolved under Article 21. Physical delivery of any material returned shall be at the Paducah Gaseous Diffusion Plant by mutual agreement of the parties and Enrichment, taking into consideration relevant provisions of the Lease Agreement between DOE and Enrichment, dated July 1, 1993 (Lease Agreement), as amended. In no event, however, shall any cylinders be returned after the date USEC completes the turnover requirements and DOE accepts return of the property pursuant to relevant provisions of the Lease Agreement. Notwithstanding any other provisions in this Agreement, including Attachment H, any adjustment and title transfer required under this section 9.03 shall be at no cost to DOE.
