This Fifth Amendment to the Distribution and Services Agreement (this “Fifth Amendment”) is made by and between BioStem Technologies, Inc., a Florida corporation (“Company”) and Venture Medical, LLC, a Montana limited liability company (“Distributor”), and is effective as of December 17, 2025 (the “Fifth Amendment Effective Date”).

WHEREAS, the Parties entered into a Distribution and Services Agreement effective September 8, 2023 (the “Original Agreement”), as previously amended by the First Amendment to the Distribution and Services Agreement dated March 1, 2024 (the “First Amendment”), the Amended and Restated Second Amendment to the Distribution and Services Agreement dated October 8, 2024 (the “Amended and Restated Second Amendment”), the Third Amendment to the Distribution and Services Agreement dated June 1, 2025 (the “Third Amendment”), and the Fourth Amendment to the Distribution and Services Agreement dated July 17, 2025 (the “Fourth Amendment”). The Original Agreement, as amended by the First Amendment, the Amended and Restated Second Amendment, the Third Amendment, and the Fourth Amendment is referred to herein as the “Current Agreement”; and

NOW THEREFORE, in consideration of the mutual covenants and agreements contained herein and for other good and valuable consideration, the Parties hereby agree as follows:

(b) Title and Risk of Loss of Consigned Product. Distributor acknowledges that Products provided to Distributor pursuant to this Section 6.A are provided as part of a consignment arrangement, and the relationship of Company and Distributor as to Consigned Product is that of a ▇▇▇▇▇▇ and bailee, respectively.

In addition, Company shall:

(h) Price of Consigned Product. The purchase price payable by Distributor for Consigned Products sold (i.e., shipped) by Distributor to an Account during the Consignment Order Period shall be [***] per square centimeter of Consigned Product. The purchase price payable by Distributor for Consigned Products sold (i.e., shipped) by Distributor to an Account following the Consignment Order Period shall be at a price to be determined in a subsequent amendment or new agreement to be agreed in writing by the Parties prior to January 1, 2026.

(i) Invoicing and Payment of Consigned Product.

	(i)	Upon shipment of Consigned Product to an Account, Distributor shall notify Company of such Consigned Product sale and shipment date, at which point Company shall invoice Distributor for its purchase of the Consigned Product.
