LETTER TO SHAREHOLDERS WHO ARE RECORD HOLDERS OF

ALR TECHNOLOGIES INC.

Up To 127,522,227 Shares of Common Stock

Issuable Upon the Exercise of Subscription Rights

December 11, 2020

Dear Shareholder:

This notice is being distributed by ALR Technologies Inc. (the “Company”) to all holders of record (the “Record Holders”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”), as of 5:00 p.m., Eastern Time, on December 11, 2020 (the “Record Date”), in connection with the distribution in a rights offering (the “Rights Offering”), at no charge, of non-transferable subscription rights (the “Subscription Right(s)”) to subscribe for and purchase shares of Common Stock at a subscription price of $0.05 per share (the “Subscription Price”). The Rights are described in the accompanying Prospectus, dated December 4, 2020 (the “Prospectus”).

In the Rights Offering, up to an aggregate of 127,522,227 shares of Common Stock are being offered pursuant to the Prospectus. The Rights will expire if they are not exercised by 5:00 p.m., Eastern Time, on January 8, 2021 (the “Expiration Date”), unless you have used the guaranteed delivery procedures described in the Prospectus. Any Rights that are not exercised prior to 5:00 p.m., Eastern Time, on the Expiration Date will expire, have no value and cease to be exercisable for shares of Common Stock.

As described in the Prospectus, each Record Holder will receive one (1) Subscription Right for each share of Common Stock owned of record as of 5:00 p.m., Eastern Time, on the Record Date. Each Subscription Right gives the holder thereof the right to purchase from the Company one (1) share of Common Stock at the Subscription Price of $0.05 per share. The Company will not issue fractional shares or cash in lieu of fractional shares in the Rights Offering. Instead, fractional shares resulting from the exercise of Subscription Rights will be eliminated by rounding down to the nearest whole share. As an example, if you owned 100 shares of Common Stock, you would receive 100 Subscription Rights that would entitle you to purchase 100 shares of Common Stock for $0.05 per share.

The Rights Offering does not contain an over-subscription privilege. The Company may allocate unexercised Subscription Rights at its discretion within 90 days following the Expiration Date. Any shareholder having fully exercised its Subscription Rights and wishing to receive an allocation of unexercised Subscription Rights may express interest by contacting the Company at contact@alrt.com using the subject line “Unexercised Subscription Rights”.

You will be required to submit payment in full of the aggregate Subscription Price for all of the shares of Common Stock for which you have subscribed pursuant to the exercise of the Subscription Right to Pacific Stock Transfer Company, the subscription agent for the Rights Offering (the “Subscription Agent”), by no later than 5:00 p.m., Eastern Time, on the Expiration Date. Your payment of the aggregate Subscription Price must be made in U.S. dollars for the full number of shares of Common Stock for which you have subscribed in the Rights Offering by personal check (certified or uncertified), bank draft, or money order (drawn upon a United States bank) payable to the Subscription Agent at the address set forth below. Payment may also be made by wire transfer. Please contact the Subscription Agent for wire transfer instructions. In order for your Rights to be properly and timely exercised, payment in full for the aggregate Subscription Price for all of the shares for which you have subscribed in the Rights Offering, including final clearance of any uncertified personal checks, must be received by the Subscription Agent before 5:00 p.m., Eastern Time, on the Expiration Date. Please be aware that funds paid by personal check may take at least five (5) business days to clear.

If you submit a subscription payment that is insufficient to purchase the total number of shares of Common Stock for which you subscribed, or if the number of shares you requested is not specified in the subscription documents, the payment received will be applied to exercise your Rights to the fullest extent possible based on the amount of the payment received, subject to the elimination of fractional shares, if applicable.

If you submit a subscription payment that exceeds the amount necessary to purchase the number of shares of Common Stock for which you subscribed, then the excess amount will be returned to you by the Subscription Agent, without interest or penalty, as soon as practicable following the Expiration Date.

The Rights are evidenced by subscription rights certificates (the “Subscription Rights Certificates”). Your Rights are non-transferable, meaning that you may not sell, transfer or assign your Subscription Rights Certificate to anyone else.

Enclosed are copies of the following documents:

Your prompt action is requested if you intend to participate in the Rights Offering. As described in the Prospectus, to exercise your Rights, you must properly complete and duly execute your Subscription Rights Certificate and forward it, together with payment in full of the aggregate Subscription Price for all of the shares for which you have subscribed pursuant to the Basic Subscription Right and the Over- Subscription Privilege, to the Subscription Agent. Do not send the Subscription Rights Certificate or payment to the Company.

Your properly completed and duly executed Subscription Rights Certificate, accompanied by full payment of the aggregate Subscription Price, must be received by the Subscription Agent before 5:00 p.m., Eastern Time, on the Expiration Date. Once you have exercised your Rights, you may not cancel, revoke or otherwise amend the exercise of your Rights. Any Rights that are not exercised prior to 5:00 p.m., Eastern Time, on the Expiration Date will expire, have no value and cease to be exercisable for shares of Common Stock, and you will have no further rights under them.

Additional copies of the enclosed materials may be obtained from the Company’s information agent, Pacific Stock Transfer Company, toll free at (800)785-7782, by email at info@pacificstocktransfer.com, or by mail at 6725 Via Austi Pkwy Suite 300, Las Vegas, NV 89119, United States.

Issuable Upon the Exercise of Subscription Rights

December 11, 2020

Dear Shareholder:

This letter is being distributed to securities dealers, commercial banks, trust companies and other nominees in connection with the distribution by ALR Technologies Inc. (the “Company”) to the holders of record (the “Record Holders”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”), as of 5:00 p.m., Eastern Time, on December 11, 2020 (the “Record Date”), in connection with the distribution in a rights offering (the “Rights Offering”), at no charge, of non-transferable subscription rights (the “Subscription Right(s)”) to subscribe for and purchase shares of Common Stock at a subscription price of $0.05 per share (the “Subscription Price”). The Subscription Rights are described in the accompanying Prospectus, dated December 4, 2020 (the “Prospectus”).

In the Rights Offering, up to an aggregate of 127,522,227 shares of Common Stock are being offered pursuant to the Prospectus. The Subscription Rights will expire if they are not exercised by 5:00 p.m., Eastern Time, on January 8, 2021 (the “Expiration Date”), unless you have used the guaranteed delivery procedures described in the Prospectus. Any Subscription Rights that are not exercised prior to 5:00 p.m., Eastern Time, on the Expiration Date will expire, have no value and cease to be exercisable for shares of Common Stock.

As described in the Prospectus, each Record Holder will receive one (1) Subscription Right for each share of Common Stock owned of record as of 5:00 p.m., Eastern Time, on the Record Date. Each Subscription Right gives the holder thereof the right to purchase from the Company one (1) share of Common Stock at the Subscription Price of $0.05 per share. The Company will not issue fractional shares or cash in lieu of fractional shares in the Rights Offering. Instead, fractional shares resulting from the exercise of Subscription Rights will be eliminated by rounding down to the nearest whole share. As an example, if you owned 100 shares of Common Stock, you would receive 100 Subscription Rights that would entitle you to purchase 100 shares of Common Stock for $0.05 per share.

The Rights Offering does not contain an over-subscription privilege. The Company may allocate unexercised Subscription Rights at its discretion within 90 days following the Expiration Date. Any shareholder having fully exercised its Subscription Rights and wishing to receive an allocation of unexercised Subscription Rights may express interest by contacting the Company at contact@alrt.com using the subject line “Unexercised Subscription Rights”.

You will not receive certificates evidencing the Subscription Rights for which you are the Nominee Holder. Rather, your Subscription Rights will be credited to your account electronically through the Depository Trust Company (“DTC”). All Subscription Rights are non-transferable, meaning that you may not sell, transfer or assign your Subscription Rights to anyone else.

We are asking (i) persons who beneficially own shares of Common Stock and have received the Subscription Rights distributable with respect to those shares through a broker, dealer, commercial bank, trust company or other nominee and (ii) Record Holders who prefer to have such institutions effect transactions relating to the Rights on their behalf, to contact the appropriate institution or nominee and request it to effect the transactions for them. In addition, we are asking beneficial owners who hold their Subscription Rights through a broker, dealer, commercial bank, trust company or other nominee who wish to obtain a separate Subscription Rights Certificate to contact the appropriate nominee as soon as possible and request that a separate Subscription Rights Certificate be issued.

Please notify, as soon as possible, any beneficial owners of Common Stock of the Rights Offering and the procedures and deadlines that must be followed to exercise their Subscription Rights.

Any commissions, fees, taxes or other expenses will be for the account of the holder of the Subscription Rights, and none of such commissions, fees, taxes or expenses will be paid by the Company or by Pacific Stock Transfer Company, the subscription agent for the Rights Offering (the “Subscription Agent”). The Company will pay all reasonable fees charged by the Subscription Agent.

Enclosed are copies of the following documents:

Your prompt action is requested. As described further in the Prospectus, to exercise the Rights, you must deliver the properly completed and duly executed Nominee Holder Election Form and payment in full of the aggregate Subscription Price that is required for all of the shares subscribed for pursuant to the Subscription Right, to the Subscription Agent. Do not send the Nominee Holder Election Form or payment to the Company.

The properly completed and duly executed Nominee Holder Election Form, accompanied by full payment of the aggregate Subscription Price, must be received by the Subscription Agent before 5:00 p.m., Eastern Time, on the Expiration Date. Failure to return the properly completed Nominee Holder Election Form with the correct and complete payment will result in your not being able to exercise the Subscription Rights held in your name on behalf of yourself or other beneficial owners.

All exercises of subscription rights are irrevocable. Rights not exercised before 5:00 p.m., Eastern Time, on the Expiration Date will expire, have no value and cease to be exercisable for shares of Common Stock.

Payment to the information agent can be made by wire transfer, personal check (certified or uncertified), bank draft or money order payable at par (without deduction for bank service charges or otherwise), as outlined in the prospectus. Please contact the information agent as noted in the following paragraph for wire transfer instructions.

To Our Clients:

Enclosed for your consideration are the Prospectus, dated December 4, 2020 (the “Prospectus”), and the Instructions for Use of Subscription Rights Certificates and Election Form relating to the distribution by ALR Technologies Inc.

The Rights are described in the accompanying Prospectus.

In the Rights Offering, up to an aggregate of 127,522,227 shares of Common Stock are being offered pursuant to the Prospectus. The Rights will expire if they are not exercised by 5:00 p.m., Eastern Time, on January 8, 2021 (the “Expiration Date”), unless the guaranteed delivery procedures described in the Prospectus are used. Any Subscription Rights that are not exercised prior to 5:00 pm, Eastern Time, on the Expiration Date will expire, have no value and cease to be exercisable for shares of Common Stock.

As described in the Prospectus, you will receive one (1) Subscription Right for each share of Common Stock carried by us in your account as of the Record Date. Each Subscription Right gives the holder thereof the right to purchase from the Company one (1) share of Common Stock at the Subscription Price of $0.05 per share. The Company will not issue fractional shares or cash in lieu of fractional shares in the Rights Offering. Instead, fractional shares resulting from the exercise of Subscription Rights will be eliminated by rounding down to the nearest whole share. As an example, if you owned 100 shares of Common Stock as of the Record Date, you would receive100 Subscription Rights that would entitle you to purchase 100 shares of Common Stock for $0.05 per share.

The Subscription Rights are evidenced by subscription rights certificates (the “Subscription Rights Certificates”) registered in the names of the Record Holders of the shares of Common Stock for which the Subscription Rights are being distributed. Subscription Rights are non-transferable, meaning that they may not be sold, transferred, or assigned by the holder of the Rights to any other party.

THE MATERIALS ENCLOSED ARE BEING FORWARDED TO YOU AS THE BENEFICIAL OWNER OF COMMON STOCK CARRIED BY US IN YOUR ACCOUNT BUT NOT REGISTERED IN YOUR NAME. EXERCISES OF SUBSCRIPTION RIGHTS MAY BE MADE ONLY BY US AS THE RECORD HOLDER AND PURSUANT TO YOUR INSTRUCTIONS.

Your Beneficial Owner Election Form and full payment for the aggregate Subscription Price for all of the shares of Common Stock that you have subscribed to purchase pursuant to the Subscription Right should be forwarded as promptly as possible in order to permit us to exercise Subscription Rights on your behalf in accordance with the terms of the Rights Offering.

The Rights Offering will expire at 5:00 p.m., Eastern Time, on the Expiration Date.
