This Commercial Lease Agreement (the “Agreement”) is made this 25rd day of April, 2013, between WACREB, LLC a California limited liability company (the “Owner”), and BIOLARGO, INC., a Delaware corporation, (the “Tennant”).

1.      Lease . Owner does hereby grant to Tennant a lease to use and occupy those certain premises commonly known as approximately 5,500 square feet of a larger 30,022 rentable square feet located at 3500 W. Garry Avenue, Santa Ana, CA (the “Building”) as shown on Exhibit A attached hereto (the “Premises”). The space consists of the entire front office, (approximately 4,500 square feet) and 1,500 square feet of Warehouse space as the Owner designates from time to time for the storage of materials or finished product. The term of this Lease shall commence on May 1, 2013 , and continue on a month-to-month basis; provided however, Leasor and Leasee may terminate this Lease earlier upon at least Ninety (90) days written notice for any reason. Tennant agrees to pay Owner monthly Lease fee in the amount of Three Thousand Five Hundred Seventy-Five and 00/100 Dollars ($ 3,575.00 ) , in advance, on the first day of each month during the term. Any fee payments received five (5) or more days after the beginning date of each month will be subject to a service charge equal to five percent (5%) of the unpaid amount.

2.      Security Deposit . Tennant shall deposit the amount of Three Thousand Five Hundred Seventy-Five and 00/100 Dollars ($ 3,575.00 ) with Owner as a Security Deposit upon the execution of this Agreement. If Tennant defaults with respect to any fee or other sum due to Owner as provided for in this Agreement and Tennant fails to cure such default within ten (10) days of Owner’s written notice specifying the details thereof, Owner may use any part of the Security Deposit for the payment of any fee or any other sum in default. Tennant shall not be entitled to interest on such deposit. If Tennant shall fully and faithfully perform every provision of this Agreement to be performed by it, the Security Deposit or any balance thereof shall be returned to Tennant within thirty (30) days after termination of this Agreement.

3.      Payment Methods . At the option of the Leasee, it may, in its sole discretion, choose to pay any cash obligations due by issuing to the Owner, or its designee, shares of common stock in BioLargo in lieu of cash. The number of shares to be issued as payment, shall be calculated on the following formula: the amount due, divided by the average closing price of our stock for the 20 business days prior to the due date, the sum of which shall equal the total number of shares to be issued. Rent will be due on a monthly basis paid in advance.

4.      First Payment.    Tennant shall issue 53,572 number of shares of common stock within 30 days of execution of this Agreement as payment in full for the security deposit due of $3,575.00 plus three months rent due ($3,750 x 3) which equals $11,250 for grand total of $15,000. (Calculation of the number of shares is as follows: $15,000 / $.28 = 53,572 shares)
