PURCHASE AGREEMENT

This Purchase Agreement (“Agreement”) is dated as of April 11, 2021, and is made by and between [                 ], a limited liability company organized under the laws of Delaware (“SELLER”) and ECOCHAIN BLOCK LLC, a limited liability company organized under the laws of Nevada (“BUYER”). BUYER and SELLER are sometimes hereinafter referred to as each, a “Party”, and together, the “Parties”. This Agreement is acknowledged and agreed by BUYER’s indirect parent company, MECHANICAL TECHNOLOGY, INCORPORATED (“Parent”).

WHEREAS, BUYER is in the business of cryptocurrency mining;

WHEREAS, SELLER is the owner of [    ] miners and [     ] miners;

WHEREAS, SELLER has agreed to sell to BUYER, and BUYER has agreed to buy from SELLER, certain miners pursuant to the terms of this Agreement;

NOW, THEREFORE, for and in consideration of the mutual covenants and agreements contained herein, and other good and valuable consideration, the adequacy, receipt and sufficiency of which are hereby acknowledged, the Parties mutually agree as follows:

1.1.       On April 12, 2021 (the “Effective Date”), SELLER shall sell to BUYER, and BUYER shall buy from SELLER, [                                 (      )] [    ] miners and [                 (   )] [   ] miners (the “Physical Miners”) and certain parts, equipment, attachments, improvements and accessions related thereto (the “Parts”, and together with the Physical Miners, the “Purchased Assets”)).

1.2.      SELLER represents to BUYER that Seller is the owner of the Purchased Assets, that the Purchased Assets are free and clear of all liens, charges and encumbrances, and that SELLER has full right, power and authority to sell the Purchased Assets, execute this Agreement and perform its obligations hereunder.

1.3.      BUYER represents to SELLER that Buyer has full right, power and authority to buy the Purchased Assets, execute this Agreement and perform its obligations hereunder.

2.1.      The Parties acknowledge and agree that the total hash rate of the Physical Miners (“Total Rate”) is estimated to be as follows:

2.2.      The Parties acknowledge and agree that the individual hash rate of the Physical Miners (“Miner Rate”) shall be as follows:

2.3.       The Parties acknowledge and agree that the total purchase price for the Purchased Assets (the “Total Purchase Price”) shall be determined by a Unit Price (as defined in Section 3.1) for each Virtual Miner (as hereinafter defined). As used in this Agreement, “Virtual Miner” is a term of art that represents a quantity of miners (but not actual or physical miners) determined by dividing the actual Total Rate on any date of determination by the Miner Rate. The Parties agree that the quantity of Virtual Miners using a date of determination of April 9, 2021 was (a) [                               (    )] [   ] miners, and (b) [               (   ) [   ] miners. The Parties acknowledge and agree that the quantity of Virtual Miners may be adjusted on the Effective Date based on the actual Total Rate on the Effective Date. The Parties acknowledge and agree that the quantity of Virtual Miners may be different from the quantity of Physical Miners and both quantities will be specified on the invoice issued by SELLER.

3.1.       The price of each Virtual Miner (the “Unit Price”) shall be as follows:

3.2.       As soon as commercially practicable after the Effective Date (but in any event no later than ten (10) days after the Effective Date), BUYER shall cause to be delivered to SELLER’s or Parent’s then existing securities broker or transfer agent or another nationally recognized independent third party acceptable to SELLER (such securities broker, transfer agent or other third party, “Share Agent”) a number of Parent Shares as determined pursuant to clauses (a) and (b) of Section 3.1 above. The Parties acknowledge and agree that the Share Agent shall hold the Parent Shares for the benefit of SELLER and the Share Agent shall follow all trading instructions with respect to such Parent Shares originated by SELLER only, subject to Section 3.3 below. BUYER shall copy SELLER on its communication to the Share Agent describing the amount of Parent Shares being delivered and the foregoing instructions.

3.3.       SELLER acknowledges and agrees that during the period beginning on the date on which the Parent Shares are delivered to the Share Agent and ending on the six (6) month anniversary of the delivery thereof, SELLER shall not, directly or indirectly, (i) offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of, any Parent Shares, (ii) enter into any swap, hedge or other agreement or arrangement that transfers in whole or in part, the economic risk of ownership of any Parent Shares (regardless of whether any such arrangement is to be settled by the delivery of securities of Parent, securities of another person, cash or otherwise), (iii) engage in any short selling of any Parent Shares, (iv) agree to do any of the foregoing or (v) publicly announce the any intention to do any of the foregoing.

4.1.       Delivery of the hash rate represented by the Virtual Miners (which, for the avoidance of doubt, includes the hash rate of the Physical Miners) shall be made through transfer of the current pool settings to BUYER’s settings on the Effective Date. Upon completion of such transfer, SELLER shall notify BUYER of the total hash rate delivered and the quantity of Virtual Miners representing it.

4.2.       BUYER acknowledges and agrees that the Physical Miners are located at the SELLER’s property and shall continue to be hosted by SELLER at such location until BUYER instructs SELLER otherwise.

5.1.       During the period of time that SELLER hosts the Physical Miners, BUYER shall be responsible for hosting fees in the amount of $9.65 (nine dollars sixty-five cents) per Physical Miner per month plus actual power charges of Physical Miners, which charges are passed through by SELLER to BUYER. Within one (1) business day after the delivery of the hast rate of the Virtual Miners, BUYER agrees to pay to SELLER an initial deposit of $50,000 (fifty thousand dollars). On the 20^th day of each month, SELLER shall invoice BUYER an amount equal to the estimate of the total power charges used by the Physcial Miners plus the hosting fees of $9.65 (nine dollars sixty-five cents) per Physical Miner for the subsequent month (and taking into account any deposits previously made and not applied against actual charges) and BUYER shall make a deposit in the amount of such preliminary invoice at least five (5) days prior to the end of each month (each, a “Deposit”). If BUYER does not make the Deposit if and as required pursuant to the preceding sentence, SELLER shall have the right to temporarily disconnect power to BUYER until such Deposit is made. Each month, SELLER shall provide an invoice showing a credit of such Deposit against the actual charges for such month. If the Deposit is greater than the actual charges, such Deposit shall be retained by SELLER and applied against power consumed in subsequent months. If the Deposit is less than the actual charges, BUYER shall reimburse such difference on or prior to the last business day of the applicable month.

5.2.       Upon the relocation of the Physical Miners to any premises leased by the BUYER (such date, the “Relocation Date”), this Section 5 shall no longer apply.

THE PHYSICAL MINERS ARE SOLD “AS IS” AND SELLER, NOT BEING THE MANUFACTURER OF THE MINERS OR THE MANUFACTURER’S AGENT, MAKES NO WARRANTY OR REPRESENTATION WHATSOEVER, EXPRESS OR IMPLIED, AS TO THE MERCHANTABILITY, FITNESS FOR ANY PARTICULAR PURPOSE, DESIGN OR CONDITION OF THE PHYSICAL MINERS, OR INTELLECTUAL PROPERTY RIGHTS (INCLUDING WITHOUT LIMITATION, ANY PATENT, COPYRIGHT AND TRADEMARK RIGHTS, OF ANY THIRD PARTY WITH RESPECT TO THE MINERS, WHETHER RELATING TO INFRINGEMENT OR OTHERWISE) WITH RESPECT TO THE MINERS. SELLER SHALL NOT BE RESPONSIBLE FOR ANY DIRECT, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING FROM POSSESSION OR USE OF THE PHYSICAL MINERS.
