Dear Mr. Zhang:

Re:Toll Processing Agreement

This letter agreement (the "Agreement") sets out the terms and conditions pursuant to which Adastra Labs Holdings Ltd. ("Adastra") will provide standard processing services to SynerGenetics Bioscience Inc. ("Company" or "Client") (collectively, the "Transaction"). Adastra and Client are known individually as a "Party" and jointly as the "Parties".

The completion of the Transaction is expressly subject to the satisfaction of the conditions set forth below:

(a)both Parties receipt of their independent requisite licenses issued by Health Canada;

(b)bulk transfer approval by Health Canada, if required; and

(c)receipt of regulatory approval, as required, of the Transaction and this Agreement. (collectively, the "Conditions Precedent").

1.Transaction

1.1.Definitions

A.Smalls - smaller size cannabis flower buds that are larfy (not dense) and typically of lower potency than other cannabis flowers.

B.Shake - small pieces of cannabis flower that break from larger cannabis buds, generally as the result of regular handling.

C.Trim - the material resulting from the process of removing excess material from cannabis flower buds.

D.Kief - the cannabinoid containing trichome glands that have been separated (sifted) from cannabis flowers and green plant material.

Adastra – SGB – Cannabis Toll Processing Agreement  Page 1 of 10

E.Winterization - the process of diluting cannabis or hemp extraction with food-grade ethanol and storing the solution in a sub-zero Fahrenheit freezer to cause waxes and lipids to come out of solution for removal by filtration.

F.Cannabis (Hemp) Oil - oil (cannabinoids and essential oils) extracted from cannabis (hemp) plant biomass using a solvent (CO2, Ethanol or other hydrocarbon). If required, the extracted oil is winterized and filtered to remove waxes and lipids. All solvent is removed from the resultant oil. If terpenes are recovered as part of the extraction process, they are re-added to the resultant oil.

G.Cannabis (Hemp) Distillate - cannabis (hemp) oil that is further distilled using short path distillation, wiped film distillation, or other distillation equipment to achieve a higher cannabinoid concentration.

H.Standard Processing - to alter the chemical or physical properties of cannabis and/or hemp by the use of a solvent to produce cannabis oil, hemp oil, cannabis distillate, or hemp distillate. This further includes preparation of these oils and distillates into specific formulations for various cannabis or hemp consumer packaged goods products.

I.Cannabis Distillate Formulation - product derived from distillate through mixing with terpenes and/or diluent(s) without further processing (e.g. sonication, recrystallization etc.)

J.Quality Assurance Agreement has the meaning set forth in section 1.3.

1.2.Subject to the satisfaction of the Conditions Precedent, beginning January 15, 2021 (the "Commencement Date"), the Parties agree to the following:

A.Client shall provide Adastra with hemp flower ("Biomass Material") for standard processing by Adastra on behalf of Client to produce hemp CBD distillate (>70% total cannabinoid concentration) ("Final Product") and, together with the Biomass Material, ("Product").

B.Biomass Material that has been sifted to remove kief and/or contains fan leaves, stems and/or seeds, will result in lower yields and lower quality extracts. Client will only provide un-sifted Biomass Material.

C.The minimum Biomass Material batch size to be provided from Client to Adastra shall be no less than a minimum of 500 kilograms (KG) up to 1,500 KG. Client will provide Adastra proposed batch sizes and dates for delivery as soon as available but at no less than 21 days in advance of the desired start of processing services.

D.Following the initial review of processing service fees discussed below, a Party seeking an amendment to either the service fees or purchase prices must notify the other Party, setting out the current and proposed pricing for the relevant Product and the justification for the proposed amendment, no less than 2 months prior to the proposed price amendment becoming effective.

E.Adastra's fee for processing services provided to the Client will be $2,000 per kilogram of the Final Product output with a minimum processing services fee equivalent to a Final Product output of 5% of the input Biomass Material (e.g. 1,000 KG of input Biomass Material would have a minimum processing service fee of $100,000). The Parties agree to re-evaluate this processing services fee after the first 1,000 KG of Biomass Material is processed.

F.The Product must meet quality standards, as evidenced by a Certificate of Analysis provided by a licensed cannabis analytical testing laboratory, and as specified in Health Canada Cannabis Regulations for potency, pesticides, heavy metals, mycotoxins, residual solvents, microbial contaminants, and foreign matter. Further, the Biomass Material will meet the requirements of the Quality Assurance Agreement.

H.In the event that Biomass does not meet quality standards as specified in Health Canada Cannabis Regulations, the Parties may agree to process the Biomass to determine if the extraction process will be remediated in the Final Product.

I.The Client acknowledges the risk that certain contaminants such as pesticides and heavy metals that may be below the limit in Biomass may be concentrated in the extraction process to higher than the limit allowed by Health Canada regulations in the Final Product rendering it unusable for sale or requiring remediation. In such cases there is no penalty for either Party and Adastra has the right to return unprocessed Biomass at no cost to Adastra. Adastra has the right to receive its fee for processing services of Biomass Material described above.

J.Adastra shall process the Biomass Material at its facility, and the processed Biomass Material shall consist of Final Product in containers mutually agreed upon by the Parties.

K.The purchasing Party shall pay to the selling Party all sales taxes applicable to the purchase of the Product. All costs of shipping as well as any customs charges, duties, or any other charges that arise as a result of or in connection with the transport of the Product shall be for the account of purchasing Party.

L.Client will be responsible for secure shipment of Biomass Material to Adastra and Adastra will be responsible for secure shipment of the Final Product to Client, if required. The delivering Party will apply commercially reasonable efforts to ensure the Product is in good condition when it is delivered and is delivered by the target delivery date. Title in and to the Product shall remain with the delivering Party until the Product is delivered to receiving Party, at which time title is transferred to receiving Party. All liability and risk of loss for the Product remains with the delivering Party until the Product is delivered to receiving Party.

M.In the event that a Party, determines in good faith or is required by Health Canada that it is required to initiate a recall with respect to a batch of a Product the recalling Party shall immediately notify the other Party of the recall and both Parties agree to cooperate with one another to accommodate any procedures and requirements necessitated by such recall.
