1.6 Notice of Cancellation or Material Change

All policies of insurance required under this Exhibit D shall provide that the insurer will give at least thirty (30) days' prior written notice to Owner and the Administrative Agent of cancellation, non-renewal, or any material change in coverage, scope, or limits, except that ten (10) days' prior written notice shall be given in the event of cancellation for non-payment of premium.

1.8 No Limitation on Liability

The insurance requirements set forth in this Exhibit D are minimum requirements and shall in no way limit, restrict, or diminish the Contractor's indemnity obligations, defense obligations, or other liabilities under the Agreement, including, without limitation, those set forth in Article 12 (Indemnification) of the Agreement. Any coverage maintained by Contractor in excess of the minimum limits specified herein shall also inure to the benefit of and be available to the Additional Insureds. The procurement of insurance by Contractor shall not be construed as satisfying any liability or obligation of Contractor under the Agreement, nor shall it relieve Contractor from liability in excess of or outside the coverage provided by such insurance.

If Owner elects to implement an OCIP, Owner shall provide Contractor with written notice of such election, together with a description of the OCIP coverages, the OCIP Manual, and enrollment procedures, no less than sixty (60) days prior to the effective date of the OCIP (or such shorter period as may be agreed by the parties). Contractor and all eligible subcontractors and sub-subcontractors shall enroll in the OCIP in accordance with the OCIP Manual and shall comply with all OCIP enrollment, safety, and reporting requirements.
6.2 Effect on Contractor's Insurance
Upon implementation of an OCIP, the Contractor's obligation to maintain Commercial General Liability, Excess/Umbrella Liability, and Workers' Compensation coverages (to the extent such coverages are replaced by the OCIP) shall be suspended for enrolled parties for on-site operations within the scope of the OCIP, effective as of the OCIP enrollment date; provided, however, that Contractor shall continue to maintain at all times:
(a) CGL, Workers' Compensation, and Excess/Umbrella coverage for off-site operations and activities not within the scope of the OCIP;
(b) Business Automobile Liability insurance as required by Section 2.2;
(c) Contractor's Pollution Liability insurance as required by Section 2.5;
(d) Professional Liability insurance as required by Section 2.6 (if applicable); and
(e) Any other insurance required by this Exhibit D that is not expressly replaced by the OCIP.
6.3 Insurance Cost Adjustment
If an OCIP is implemented, the GMP shall be equitably adjusted to reflect the deletion of insurance costs that were included in Contractor's and subcontractors' pricing for coverages now provided through the OCIP. Such adjustment shall be processed through the change order procedures set forth in Article 7 of the Agreement. Owner's analysis through Northgate Insurance Brokerage, LLC estimates that implementation of an OCIP would produce premium savings of approximately twelve percent (12%) to fifteen percent (15%) of insurable construction costs. The parties shall cooperate in good faith to identify and quantify the insurance cost components included in the GMP and in each subcontract, and to agree upon a fair and equitable adjustment.
6.4 OCIP Tail
If an OCIP is implemented, Owner shall procure a completed operations tail under the OCIP of no less than ten (10) years from the date of final completion and acceptance of all Work, covering claims arising out of completed operations at the Project site. The cost of the OCIP completed operations tail shall be an Owner expense and shall not be charged to Contractor or included in the GMP.
SECTION 7: CERTIFICATES OF INSURANCE AND EVIDENCE OF COVERAGE
7.1 Initial Delivery
Contractor shall deliver to Owner and the Administrative Agent complete certificates of insurance evidencing all required coverages under this Exhibit D no later than ten (10) business days prior to the Notice to Proceed date (NTP target: November 1, 2025). Such delivery is a condition precedent to the issuance of the Notice to Proceed. Certificates for Builder's Risk insurance shall be provided by Owner (or its broker, Northgate Insurance Brokerage, LLC) and shall be delivered to Contractor and the Administrative Agent prior to or concurrently with the Notice to Proceed.
7.2 Form.  All certificates of insurance shall be issued on ACORD Form 25 (Certificate of Liability Insurance) or an equivalent form providing substantially similar information. Each certificate shall clearly identify:
(a) The Project by name: "Stonebridge Data Center Campus";
(b) The Agreement date: October 20, 2025;
(c) All Additional Insureds by name;
(d) Policy numbers, effective dates, and expiration dates for each coverage;
(e) Per-occurrence and aggregate limits for each coverage;
(f) Deductible and SIR amounts; and
(g) A description of endorsements including additional insured, waiver of subrogation, and primary and non-contributory status.
Copies of all applicable endorsements (including additional insured endorsements, waiver of subrogation endorsements, and primary and non-contributory endorsements) shall accompany the certificates upon Owner's request. Certificates and endorsements shall be delivered to Owner at the address specified in Section 1.6 and to the Administrative Agent at the address specified in Section 1.6.
7.3 Renewal.  Contractor shall deliver renewal certificates to Owner and the Administrative Agent at least thirty (30) days prior to the expiration of any policy of insurance required under this Exhibit D. Renewal certificates shall evidence that the renewal policies provide coverages, limits, and endorsements at least equivalent to those required by this Exhibit D. Failure to timely deliver renewal certificates and evidence of renewal coverage shall constitute a default under the Agreement, and Owner may (but shall not be obligated to) procure replacement coverage on Contractor's behalf at Contractor's sole cost and expense, including any premium, broker's fee, or other charge associated with such replacement coverage, and may deduct such costs from any amounts otherwise due to Contractor under the Agreement.
7.4 Right to Review Policies
Owner and the Administrative Agent shall have the right, at any time and from time to time, to review complete copies of all insurance policies (not merely certificates of insurance) required under this Exhibit D. Contractor shall provide complete, unredacted copies of such policies within ten (10) business days of receipt of a written request from Owner or the Administrative Agent. In the event that any policy does not conform to the requirements of this Exhibit D, Contractor shall cause such policy to be amended by endorsement to achieve conformity within fifteen (15) business days of Owner's written notice of the deficiency.
7.5 Lender Compliance
All insurance coverages and evidence thereof must comply with the insurance requirements set forth in the Construction Loan Agreement among Stonebridge Campus Holdings LLC (as Borrower), Summit National Bank, N.A. (as Administrative Agent), Cascade Commercial Lending Corp., and Harborview Trust Company (collectively, the "Lenders"), as the same may be amended, restated, supplemented, or otherwise modified from time to time. In the event of any conflict between the requirements of this Exhibit D and the insurance requirements of the Construction Loan Agreement, the more stringent requirements shall govern, unless otherwise agreed in writing by Owner and the Administrative Agent. Contractor shall cooperate with Owner in providing any additional insurance documentation, endorsements, or certifications required by the Lenders in connection with the construction loan.
SECTION 8: CLAIMS PROCEDURES AND COOPERATION
8.1 Prompt Notice
Contractor shall promptly notify Owner in writing of any accident, occurrence, injury, claim, suit, demand, or threatened claim arising out of or in connection with the Work that may give rise to a claim under any policy of insurance required by this Exhibit D. Such notification shall be made in no event later than forty-eight (48) hours after Contractor (or any officer, employee, superintendent, or agent of Contractor) becomes aware of such event. The notice shall include a detailed description of the event, the date and location of occurrence, the names and contact information of all persons involved or having knowledge of the event, the nature and extent of any injury or damage, and any other information reasonably necessary for Owner and the applicable insurer to evaluate the matter.
8.2 Cooperation.  Contractor shall cooperate fully with Owner, Owner's Representative (Kestrel Infrastructure Advisors, LLC), the insurers, and the Administrative Agent in the investigation, defense, and settlement of any claim arising out of or related to the Work or any insurance policy required under this Exhibit D. Without limiting the generality of the foregoing, Contractor shall:
(a) Preserve and make available all evidence, reports, photographs, correspondence, and documentation related to any occurrence or claim;
(b) Make Contractor's employees, agents, and representatives available for interviews, depositions, hearings, and trial testimony as reasonably requested;
(c) Provide access to the Project site and to Contractor's records for inspection by Owner, insurers, adjusters, and their representatives;
(d) Execute any and all documents and instruments necessary to facilitate the processing and settlement of any claim; and
(e) Not take any action that would prejudice or impair the rights of any insured party or insurer under any applicable policy.
8.3 No Settlement Without Consent
Contractor shall not settle, compromise, or consent to the entry of any judgment with respect to any claim, action, or proceeding that could (a) affect Owner's insurance coverage under any policy required by this Exhibit D, (b) impair or affect the Project, the Work, or the value thereof, (c) create any lien or encumbrance on the Project or any portion thereof, or (d) adversely affect the Lenders' collateral or security interest, without the prior written consent of Owner and the Administrative Agent, which consent shall not be unreasonably withheld, conditioned, or delayed with respect to claims that do not exceed $500,000 in the aggregate.
SECTION 9: CROSS-REFERENCE TO CONSTRUCTION LOAN AGREEMENT REQUIREMENTS
9.1 Collateral Assignment
Contractor acknowledges and agrees that Owner's rights under the Builder's Risk policy and all other Project insurance policies (to the extent such policies cover the Project or the Work) will be collaterally assigned to Summit National Bank, N.A. as Administrative Agent, pursuant to the Assignment of Contracts, Permits, and Approvals executed in connection with the $390,000,000 senior secured construction loan facility (Summit Loan Commitment Reference: CL-2025-VA-04418). Contractor consents to such collateral assignment and agrees to cooperate with Owner and the Administrative Agent in connection therewith, including by executing any acknowledgments, estoppels, or consents reasonably requested by the Administrative Agent.
9.2 Mortgagee / Loss Payee
All property insurance policies covering the Project (including, without limitation, the Builder's Risk policy described in Section 3) shall include a standard mortgagee clause or loss payee endorsement in favor of:
Summit National Bank, N.A. as Administrative Agent 1275 Avenue of Commerce, 12th Floor McLean, Virginia 22102
Such endorsement shall provide that the interest of the Administrative Agent shall not be invalidated by any act or neglect of the mortgagor or owner of the insured property, and that the insurer shall give the Administrative Agent not less than thirty (30) days' prior written notice of cancellation, non-renewal, or material change in coverage.
9.3 LTC Covenant Compliance
Contractor acknowledges that insurance proceeds received under the Builder's Risk policy or any other property insurance policy, to the extent such proceeds are not applied to the restoration and repair of the damaged Work, shall be treated in accordance with the provisions of the Construction Loan Agreement governing casualty and condemnation proceeds. Without limiting the foregoing, such proceeds shall be applied in a manner consistent with the maintenance of the loan-to-cost ratio covenant of ≤ 65% set forth in the Construction Loan Agreement, and shall be deposited into the Insurance Proceeds Account established with the Administrative Agent, as applicable. Contractor shall cooperate with Owner and the Administrative Agent in the application of insurance proceeds in accordance with the Construction Loan Agreement.
SECTION 10: SUMMARY TABLE OF MINIMUM INSURANCE REQUIREMENTS
The following table summarizes the minimum insurance requirements set forth in this Exhibit D. In the event of any conflict between this summary table and the detailed provisions of Sections 1 through 9, the detailed provisions shall control.
SECTION 11: MISCELLANEOUS
11.1 No Waiver
The failure of Owner or the Administrative Agent at any time to require evidence of insurance, to identify a deficiency in Contractor's or any subcontractor's insurance, or to demand strict compliance with any provision of this Exhibit D shall not be deemed a waiver of Owner's or the Administrative Agent's rights hereunder, nor shall it relieve Contractor of any of its obligations under this Exhibit D. All rights and remedies of Owner and the Administrative Agent under this Exhibit D are cumulative and are in addition to any other rights and remedies available under the Agreement, at law, or in equity.
11.2 Survival.  The obligations of Contractor under this Exhibit D shall survive the expiration or earlier termination of the Agreement to the extent necessary to fulfill any completed operations tail period, extended reporting period, warranty-period bond obligation, or other insurance or bonding obligation that, by its terms, extends beyond the Term of the Agreement. Without limiting the foregoing, Contractor's obligations under Sections 2.1.4 (Completed Operations Tail), 2.5.3 (Pollution Liability Term), 2.6.3 (Professional Liability Extended Reporting Period), 4.1.5 (Performance Bond Duration), and 4.2.5 (Payment Bond Duration) shall survive in accordance with their respective terms.
11.3 Governing Law
This Exhibit D shall be governed by and construed in accordance with the laws of the Commonwealth of Virginia, without regard to its conflicts of law principles. Any dispute arising out of or relating to this Exhibit D shall be resolved in accordance with the dispute resolution provisions set forth in the Agreement.
11.4 Amendments.  This Exhibit D may be amended, modified, or supplemented only by a written instrument duly executed by both Owner and Contractor. To the extent any proposed amendment would reduce coverages, limits, or other protections below the levels required by the Construction Loan Agreement, the prior written consent of the Administrative Agent (Summit National Bank, N.A.) shall also be required as a condition to the effectiveness of such amendment. No oral agreement, course of dealing, or trade usage shall operate to modify the requirements of this Exhibit D.
