3.4     CBI Subcontract

3.4.1     For the CBI Subcontract that is designated a Contractor-Managed Subcontract as of the date of this Amendment, in the event that CBI Services, LLC or its successor(s) files for or is involuntarily put into bankruptcy (a “Bankruptcy Event”), the Parties agree to the following process for Contractor to obtain adjustments to the Target Completion Dates, the Baseline Schedule and/or Target Construction Cost:

i. Contractor shall provide written notice to Owners of the occurrence of a Bankruptcy Event that: (i) has caused or will cause a material adverse impact on Contractor’s, Contractor’s Subcontractor’s and/or Contractor-Managed Subcontractor’s ability to perform its work in accordance with the Project Schedule in effect as of the Bankruptcy Event and causes a delay to the critical path in the Project Schedule for

2

CONFIDENTIAL AND PROPRIETARY

achievement of either or both Unit Mechanical Completion Dates or (ii) has caused or will cause a material increase to the Combined Construction Costs (either (i) or (ii), a “Bankruptcy MAI”), (provided, however, for purposes of determining whether a Bankruptcy MAI has occurred, the fact that the Bankruptcy Event was or could be attributable to the acts or omissions of CBI Services, LLC or its personnel shall not be considered or in any way disqualify the Bankruptcy Event as justification for the adjustments contemplated by this Section 3.4). Such notice shall be provided as promptly following such Bankruptcy MAI as practicable, but, (and notwithstanding Section 10.4.1 or Section 11.4.1) in any case, within fourteen (14) Days of the Bankruptcy MAI; provided, however, that failure to timely provide such notice shall not preclude Contractor’s rights hereunder with respect to such Bankruptcy MAI. Contractor shall provide all available information related to the Bankruptcy MAI promptly as it becomes available to Contractor. After Owners’ receipt of such notice, the Parties shall have ninety (90) days to negotiate an adjustment to Contractor’s Target Completion Dates, the Baseline Schedule and/or Target Construction Cost, as applicable such that Contractor is not materially adversely impacted by the Bankruptcy Event.

ii. If Owners do not agree that a Bankruptcy MAI occurred, Owners shall initiate the dispute resolution process set forth in Article 38 of this Agreement within thirty (30) days after Owners’ receipt of the notice from Contractor under Section 3.4.1(i). The sole issue for determination by the DRB shall be whether a Bankruptcy MAI occurred (and not the amount of any adjustments to the Target Completion Dates, the Baseline Schedule and/or the Target Construction Cost that Contractor claims). In the DRB proceeding, Contractor shall have the same burden of proof as would apply for a Change Order dispute under this Agreement.

iii. If the DRB determines that a Bankruptcy MAI did not occur, the CBI Subcontract shall remain a Contractor-Managed Subcontract and Contractor shall not be entitled to any adjustment to the Target Completion Dates, the Baseline Schedule and/or Target Construction Cost at such time; provided, however, such a finding shall be without prejudice to Contractor’s right to notify Owners of a future Bankruptcy MAI associated with the same Bankruptcy Event if additional impacts to Contractor result therefrom.

iv. If the DRB determines that a Bankruptcy MAI occurred, or if Owners did not disagree that a Bankruptcy MAI occurred pursuant to subpart (ii) above, the Parties shall continue to negotiate equitable adjustments to the Target Completion Dates, the Baseline Schedule and/or Target Construction Cost (consistent with any applicable provisions of this Agreement governing such adjustments but without limiting the rights of either of the Parties under this Section 3.4) for the ninety (90) day period contemplated above by subpart (i). Any such adjustments agreed

3

CONFIDENTIAL AND PROPRIETARY

upon during this negotiation period promptly shall be incorporated into a Change Order executed by the Parties.

Notwithstanding the foregoing, the Parties agree that the ultimate duration and outcome of a Bankruptcy Event may not be known within ninety (90) days of a Bankruptcy MAI. Accordingly, the Parties agree that the impacts resulting from the Bankruptcy Event may be ongoing and may result in multiple Change Orders or modifications to a Change Order following the process set forth herein as the impacts are realized over time, notwithstanding Section 12.6 of the Agreement or any other provision of this Amendment or the Agreement to the contrary. The process is intended to be repeated, as necessary, to address the impacts of the Bankruptcy Event.

v. If the Parties cannot agree on the above adjustments within the ninety (90) day period set forth above in subpart (i), the CBI Subcontract shall convert to an Owner-Managed Subcontract on the ninety-first (91^st) day; provided, however, the ninety (90) day period set forth in subpart (i) above shall be tolled during the pendency of any dispute under subpart (ii) above or may be extended by mutual agreement of the Parties. The conversion to an Owner-Managed Subcontract shall be deemed to occur on the date of Contractor’s notice under subpart (i) above in the event that either the Owner did not disagree that a Bankruptcy MAI occurred or that the DRB determines the Bankruptcy MAI occurred (the “Conversion Date”). Contractor shall then be entitled to seek (and Owners will be entitled to contest) any adjustments to the Target Construction Cost and/or Target Completion Dates and Baseline Schedule under the Agreement based on the CBI Subcontract being an Owner-Managed Subcontract from the Conversion Date; provided, the start date for purposes of the deadlines for submittals required under Sections 10.4 and 11.4 shall be tolled until the actual date (on or after the 91^st day) on which the CBI Subcontract is converted to an Owner-Managed Subcontract (as opposed to the Conversion Date above). As a result of this conversion, the Parties shall execute a Change Order reducing: (i) the Target Construction Cost to account for the conversion of the CBI Subcontract as of the Conversion Date (including, in addition to the direct value associated with remaining scope, removal of a portion of the following to the extent such amounts support the remaining scope of the CBI Subcontract: (a) Contractor’s contingency, and (b) Field Indirects); and (ii) Contractor’s Earned Fee calculated at [***] ([***]) of the amount deducted in the immediately preceding subsection (i). This deductive Change Order will not limit Contractor’s ability to pursue Change Order(s) associated with the cost and schedule impacts related to the CBI Subcontract as an Owner-Managed Subcontract.

vi. At all times prior to any conversion (actual conversion, not the deemed Conversion Date), Contractor shall continue to manage the CBI Subcontract as a Contractor-Managed Subcontract. Following actual

4

CONFIDENTIAL AND PROPRIETARY

conversion, Contractor shall continue to support mitigation efforts and the transition of CBI Subcontract scope to Owners, but Owners shall have sole authority to direct the actions of CBI Services, LLC following the conversion.

3.4.2    The Parties shall develop a mitigation plan for a Bankruptcy Event, which may include Contractor and/or Southern Nuclear obtaining necessary ASME N-Stamp(s) and construction and engineering planning for transfer of the CBI Subcontract scope to other parties. Contractor shall support development and implementation of this mitigation plan to the extent permitted under applicable Law, and all associated costs shall be Excluded Costs.

Section 1.8Not Used

Section 1.9Section 10.2(i) is hereby modified by removing the word “and” after the semicolon.

Section 1.10Section 10.2(ii) is hereby modified by inserting “and Section 10.3” after the reference to “Section 10.4” and by deleting the period and adding “; and” in its place.

Section 1.11Section 10.2 shall be amended to add a new subsection (iii) immediately following 10.2(ii) as follows:

(iii)     adjustments under Section 3.4.1(iv) (negotiated adjustments that do not result in conversion of the CBI Subcontract to an Owner-Managed Subcontract) following a Bankruptcy Event, in accordance with the procedure and applicable standards set forth in Section 3.4.1.

Section 1.12Section 11.2(ii) is hereby modified by removing the word “and” after the semicolon and by inserting “and Section 11.3” after the reference to “Section 11.4”.

Section 1.13Section 11.2(iii) is hereby modified by deleting the period and adding “; and” in its place.

Section 1.14Section 11.2 shall be amended to add a new subsection (iv) immediately following 11.2(iii) as follows:

(iv)     adjustments under Section 3.4.1(iv) (negotiated adjustments that do not result in conversion of the CBI Subcontract to an Owner-Managed Subcontract) following a Bankruptcy Event, in accordance with the procedure and applicable standards set forth in Section 3.4.1.

Section 1.15Section 11.3 shall be amended by adding the following text after the last sentence.

Without limiting the application of any other provision regarding claims for adjustments to the Target Construction Cost, to the extent Contractor believes it is entitled to an adjustment for Field Indirects resulting from an Adjustment Event, the following provisions shall apply:

5

CONFIDENTIAL AND PROPRIETARY

(i) If the requested Target Construction Cost adjustment for an individual Adjustment Event (excluding Field Indirects) is greater than [***] dollars ($[***]), Contractor may include the Field Indirect costs associated with the Adjustment Event in the Change Order request associated with such Adjustment Event submitted under Section 11.4.

(ii) If the requested Target Construction Cost adjustment for an individual Adjustment Event (excluding Field Indirects) is less than or equal to [***] dollars ($[***]) (“Below-Threshold Adjustment Event”), an adjustment for Field Indirects will be deferred. Field Indirects will be excluded from any Change Order issued in connection with the Below-Threshold Adjustment Event; however, such Change Order may include a reservation with respect to deferred Field Indirects. When the cumulative value of Below-Threshold Adjustment Events (events for which a Change Order has been issued) exceeds [***] dollars ($[***]) in the aggregate, Contractor may then submit a Change Order request under Section 11.4 for such unpaid aggregate amount of all Field Indirects associated with such Below-Threshold Adjustment Events, notwithstanding Section 12.6 or any other statement regarding Change Order finality set forth herein, but subject to substantiation of the entitlement to the appropriate percentage used for each Below-Threshold Adjustment Event. Following such adjustment, Contractor will not be entitled to further adjustments for Field Indirects associated with the Below-Threshold Adjustment Events that were aggregated to reach the [***] dollar ($[***]) threshold. The process of aggregating the overall cost impacts of Below-Threshold Adjustment Events to [***] dollars ($[***]), and then submitting Change Order requests for Field Indirects may be repeated throughout the Project; provided, nothing in this section shall allow for double counting of Field Indirects.

Section 1.16The first sentence of Section 12.1 shall be amended by adding the words “or scope to be performed under a Contractor-Managed Subcontract” after the word “hereunder” and before the parenthetical.

Section 1.17The list of Target Assumptions in Exhibit B shall be amended by adding a new section 7 after section 6:

7. Contract-specific Target Assumptions applicable to individual Contractor-Managed Subcontracts are set forth in Exhibit B, Table 12. Such Target Assumptions apply only with respect to the corresponding Contractor-Managed Subcontract.

Section 1.18Exhibit B shall be amended by adding the new Table 12 set forth in Attachment 1 to this Amendment following Table 11.
