COMMERCIAL WARRANTY FOR AUTHORIZED ROOF SCIENTIST FRANCHISEES ONLY NOT A HOMEOWNER OR CONSUMER WARRANTY

PRODUCT CONFORMITY COVERAGE FOR FRANCHISE PURCHASERS This Warranty presents the twelve-month product warranty in Section 13 of the executed Non-Exclusive Master Sale of Goods Agreement effective April 29, 2026 between HFB Franchisor Holdings, LLC and NxTech Holdings LLC (the "Agreement"), as applicable to the Roof Scientist franchise channel. It does not amend the Agreement. If this document conflicts with the Agreement, the Agreement controls the rights and obligations arising under it.

SEPARATE FROM THE FIVE-YEAR ADHESION WARRANTY This Warranty begins on delivery of the Goods. The separate five-year residential adhesion warranty begins on application and has its own eligibility and remedy provisions. The five-year warranty's registration deadline, homeowner grace period, proration, replacement-only remedy, and aggregate gallon cap do not limit rights under this twelve-month Warranty or the Agreement.

1. Covered Purchasers and Goods

This Warranty applies to Shingleton Guard goods ("Goods" or "Product") supplied by NxTech Holdings LLC ("Seller" or "Vital Coat") under the Agreement to participating Roof Scientist franchisees. Section 13 warrants the Goods to the applicable Franchisor and Franchisees identified in the Agreement. Shingleton Guard is the covered product brand; it is not a separate seller or warrantor.

2. Twelve-Month Period and Coverage

For twelve (12) months from the date of delivery, Seller warrants that the Goods will:

• Be free from defects in workmanship, design, and material;
• Conform to Seller's published specifications in effect at the time of manufacture;
• Be merchantable;
• Be free and clear of all liens, security interests, or other encumbrances; and
• Be free from infringement of third-party intellectual property.

These promises concern the supplied Goods. They do not constitute a warranty of an installer's roof preparation, application labor, or services. The contractual twelve-month period is separate from the Product's storage-dependent shelf life and the five-year adhesion warranty.

3. Storage and Shelf Life

The approved Shingleton Guard Technical Data Sheet states that unopened Product has a shelf life of up to one (1) year in its original sealed container when properly stored. Store at 40-95 degrees F (4-35 degrees C), protect from freezing, and follow the applicable Product label, Technical Data Sheet, and Safety Data Sheet.

Delivery does not establish a new manufacture date or reset a stated Product expiration date. A shelf-life statement does not shorten or replace the twelve-month contractual warranty in Section 2. Vital Coat may request storage and handling records relevant to evaluating the reported condition. Nothing in this section adds a blanket exclusion from the express promises in the Agreement.

4. Delivery Inspection and Nonconforming Goods

Under Section 10 of the Agreement, Franchisees must inspect Goods received and notify Seller within five (5) days after delivery if Goods are damaged, defective, fail to conform to specifications, or otherwise fail to conform to the applicable purchase-order specifications and Agreement. Under that section, Goods are deemed accepted upon delivery if notice has not been provided within five (5) days after delivery.

For a qualifying Section 10 notice, Seller must, at the Franchisee's direction, replace the Goods or refund their price together with the shipping expenses specified in Section 10. Goods returned or replaced under that section are shipped back at Seller's expense and risk of loss. If replacement is selected, Seller promptly ships replacement Goods at Seller's expense and risk of loss to the Franchisee location specified in the applicable purchase order.

The delivery inspection and acceptance provisions and the twelve-month product warranty are separate provisions of the Agreement. This document does not convert the five-day delivery-notice period into a five-day duration for Section 13 coverage or change the Agreement's treatment of a later-discovered defect.

5. Submitting a Warranty Claim

Submit a routine warranty claim by either of these methods:

• Online: https://shingletonguard.vitalcoreos.com/warranty-claim; select the twelve-month product-warranty claim type; or
• Email: [email protected], using the subject line "Shingleton Guard Product Warranty Claim" followed by the order or invoice number.

Provide the purchaser name and contact information, delivery address, order or invoice number, delivery date, Product identification and lot information if available, description of the concern and when it was discovered, photographs, storage history, and other reasonably available supporting records. Identify whether replacement or refund is requested under the applicable Agreement provision. Homeowner installation registration is not a condition added by this document for twelve-month product-warranty claims.

Vital Coat will acknowledge the submission and provide a claim reference and directions. Provide additional information reasonably needed to evaluate the claim and reasonable inspection access when requested. Vital Coat generally targets a written decision within thirty (30) calendar days after receiving the information and access reasonably required for review, with status updates when additional time is needed. This administrative target does not extend a contractual notice deadline. This document imposes no additional sixty-day evidence cutoff that forfeits rights under the Agreement.

Formal contractual notices: The online form and warranty email are administrative intake channels. They do not amend Section 29 of the Agreement. Where a formal notice is required under the Agreement, comply with its written-notice and delivery requirements, including nationally recognized overnight courier or certified or registered mail with return receipt requested, unless otherwise agreed under the Agreement. Seller's notice address is NxTech Holdings LLC, 668 Capital Circle NE, Suite 12, Tallahassee, Florida 32301. Do not rely solely on a routine form or email submission to satisfy a formal contractual notice requirement.

6. Remedy

If Goods fail to conform to the Section 13 warranty during the applicable warranty period, Seller's sole obligation under that section is, at the Franchisee's option, to replace the nonconforming Goods or refund the purchase price paid for them. The applicable rights and obligations remain subject to the Agreement, including Section 10 where applicable, and applicable law.

The five-year adhesion warranty's proration, aggregate gallon limit, and exclusions of shipping or other costs do not replace the remedies or shipping obligations established by the Agreement for a qualifying product claim. This document does not establish a new shipping allocation for Section 13 claims where Section 10 does not apply; the Agreement controls.

7. Other Warranties and Contract Priority

Section 13 also provides that Seller's applicable online product warranty or terms and conditions apply to the Goods listed in Exhibit A. This document is that online product warranty for the Goods listed in Exhibit A, published at the Shingleton Guard warranty hub identified in Section 8. If this document conflicts with the Agreement, the Agreement controls. The separately issued Shingleton Guard Five-Year Prorated Limited Product Adhesion Warranty applies according to its own terms. This document does not cancel that separate express warranty or expand it into a warranty of roof life, leak prevention, or installer workmanship.

Except as expressly set out in the Agreement, Seller makes no other express or implied representation or warranty, whether arising by law, course of dealing or performance, usage of trade, or otherwise, to the extent permitted by applicable law. This statement does not negate the express coverage reproduced in Section 2 or the additional warranty recognized by Section 13.

The Agreement's notice, dispute, governing-law, jurisdiction, amendment, and other applicable provisions remain controlling. This document does not substitute the five-year homeowner warranty's governing-law or venue provisions for the Agreement's provisions. Revisions to this presentation do not amend the Agreement or reduce rights already arising under it.
