ARTICLE 5 — TITLE AND SURVEY

Section 5.1 — Title Commitment

Buyer acknowledges receipt of the Title Commitment issued by Fidelitas Title & Escrow, Inc. (acting as agent for Sovereign Title Insurance Company) with an effective date of April 3, 2025, for an Owner's Title Insurance Policy in the amount of Fifty-Eight Million Five Hundred Thousand Dollars ($58,500,000) (the "Title Commitment"). The Title Commitment includes Schedule A (setting forth the proposed insured, the amount of insurance, and the estate or interest in the land), Schedule B-I (setting forth the requirements to be satisfied prior to issuance of the Title Policy), and Schedule B-II (setting forth the exceptions from coverage that will appear in the Title Policy). Buyer shall review the Title Commitment and the documents referenced therein as part of Buyer's due diligence.

Section 5.2 — Title Objections

(a) Objection Deadline. On or before the date that is thirty (30) calendar days after the Effective Date (i.e., May 15, 2025), Buyer shall deliver to Seller and to Seller's Counsel (Whitfield, Poole & Stratton LLP, Attention: Harrison Poole, Esq.) a written notice setting forth any objections to matters disclosed in the Title Commitment, the underlying title exception documents, or the Survey (each, a "Title Objection" and collectively, the "Title Objections"). Any matters disclosed in the Title Commitment or Survey to which Buyer does not timely object shall be deemed Permitted Exceptions.

(b) Seller's Response. Seller shall have fifteen (15) Business Days after Seller's receipt of Buyer's Title Objection notice within which to notify Buyer in writing whether Seller elects to cure, or to attempt to cure, each Title Objection. Seller shall have no obligation to cure any Title Objection other than the Mandatory Cure Items described in Section 5.3. Seller's failure to respond within such fifteen (15) Business Day period shall be deemed an election by Seller not to cure the subject Title Objection(s).

(c) Buyer's Election. If Seller elects not to cure, or is unable to cure, any Title Objection (other than a Mandatory Cure Item), Buyer shall have ten (10) Business Days after receipt of Seller's response (or after Seller is deemed to have elected not to cure) within which to notify Seller in writing of Buyer's election to:

(i) waive such Title Objection, in which case the matter giving rise to the Title Objection shall become a Permitted Exception and Buyer shall proceed to Closing;

(ii) if the Due Diligence Period has not yet expired, terminate this Agreement pursuant to Section 4.4, in which case the Earnest Money Deposit (less the Independent Consideration) shall be returned to Buyer; or

(iii) if the Due Diligence Period has expired, terminate this Agreement and receive a return of the Earnest Money Deposit (including all accrued interest), but only if the uncured Title Objection constitutes a "material title defect," which shall mean a title matter that (A) renders title to the Property unmarketable or uninsurable, (B) materially impairs the use of the Property for data center development, or (C) creates a lien or encumbrance in excess of Two Hundred Fifty Thousand Dollars ($250,000) that Seller is not obligated to cure as a Mandatory Cure Item.

If Buyer fails to make a timely election under this Section 5.2(c), Buyer shall be deemed to have waived such Title Objection, and the matter shall become a Permitted Exception.

Section 5.3 — Mandatory Cure Items

Notwithstanding anything in Section 5.2 to the contrary, Seller shall be unconditionally obligated to cure and remove (or cause to be cured and removed) at or prior to Closing (by payment, bonding, or otherwise), whether or not objected to by Buyer, each of the following (collectively, the "Mandatory Cure Items"):

(a) all monetary liens, deeds of trust, mortgages, security interests, and financing statements encumbering the Property, other than the Permitted Exceptions;

(b) any judgment liens against Seller that attach to the Property;

(c) any mechanic's liens, materialmen's liens, or similar statutory liens arising from work ordered by Seller or Seller's agents or contractors on the Property; and

(d) real property tax liens for delinquent real property taxes, penalties, and interest owed with respect to the Property for any period prior to the Closing Date.

Seller shall use reasonable efforts to cure all Mandatory Cure Items on or before the Closing Date. The cost of curing all Mandatory Cure Items shall be borne exclusively by Seller. At Closing, the Escrow Agent is authorized to apply a portion of the Purchase Price to the payment and satisfaction of any Mandatory Cure Items, as reflected on the settlement statement.

Section 5.4 — Survey Objections

The Title Objection procedures set forth in Sections 5.2 and 5.3 shall apply equally to matters first disclosed by the ALTA/NSPS Survey of the Property. The target completion date for the Survey is June 15, 2025. If the Survey is not completed until after the Title Objection deadline of May 15, 2025, Buyer shall have fifteen (15) Business Days after Buyer's receipt of the completed, certified Survey within which to deliver Title Objections with respect to matters disclosed by the Survey that were not previously disclosed in the Title Commitment or the underlying title exception documents. The procedures set forth in Sections 5.2(b) and 5.2(c) shall apply to any such Survey-related Title Objections, mutatis mutandis.

Section 5.5 — Title Insurance Policy

(a) Owner's Title Policy. At Closing, the Title Company shall issue, or shall irrevocably commit to issue, an Owner's Title Insurance Policy (ALTA 2006 form, as amended, or such successor form as may then be in effect) in the amount of Fifty-Eight Million Five Hundred Thousand Dollars ($58,500,000), issued by Sovereign Title Insurance Company through Fidelitas Title & Escrow, Inc., insuring fee simple title to the Property vested in Buyer (or Buyer's permitted assignee), subject only to the Permitted Exceptions (the "Title Policy"). The premium for the Owner's Title Policy shall be paid by Buyer.

(b) Extended Coverage and Endorsements. Buyer may request that the Title Company issue the Title Policy with extended coverage (deletion of the standard survey exception, parties in possession exception, mechanic's lien exception, and other standard printed exceptions) and such endorsements as Buyer may reasonably require, including ALTA 3.1 (Zoning), ALTA 9 (Comprehensive), ALTA 17 (Access and Entry), ALTA 18 (Single Tax Parcel), ALTA 19 (Contiguity), ALTA 25 (Same as Survey), ALTA 28 (Easement – Damage or Enforced Removal), and ALTA 35 (Minerals and Other Subsurface Substances). The cost of extended coverage and all endorsements shall be borne by Buyer. Seller shall execute such affidavits, certifications, and other documents as the Title Company may reasonably require in connection with the issuance of extended coverage and endorsements.

(c) Lender's Title Policy. In connection with Buyer's anticipated construction financing for the Project, Buyer may request the Title Company to issue a Lender's Title Insurance Policy (ALTA 2006 Loan Policy form) in the amount of up to Three Hundred Ninety Million Dollars ($390,000,000) in favor of Buyer's construction lender(s). The premium and cost of the Lender's Title Policy shall be borne by Buyer. Seller's cooperation with the issuance of a Lender's Title Policy is addressed in Section 8.7.

Section 5.6 — Permitted Exceptions

The "Permitted Exceptions" shall consist of the following:

(a) those specific title exception items listed on Exhibit B attached hereto;

(b) those matters disclosed in the Title Commitment or the Survey to which Buyer does not timely object, or which Buyer waives or is deemed to have waived, pursuant to this Article 5;

(c) the lien of real property taxes and assessments not yet due and payable as of the Closing Date;

(d) zoning and land use regulations of Loudoun County, Virginia, applicable to the Property (current zoning: PD-IP);
