Storage Trust, Inc., including purchases made pursuant to our Automatic Investment Program, you agree that, if you fail to meet the suitability requirements for making an investment in shares or can no longer make the other representations or
warranties set forth in this Section 7, you are required to promptly notify Strategic Storage Trust, Inc. and your Broker-Dealer in writing.

TAXPAYER IDENTIFICATION NUMBER OR SOCIAL SECURITY NUMBER CERTIFICATION (required): The investor signing below, under penalties of perjury, certifies that (1) the number shown on this Subscription Agreement
is my correct taxpayer identification number (or I am waiting for a number to be issued to me), (2) I am not subject to backup withholding because I am exempt from backup withholding, I have not been notified by the Internal Revenue Service
(IRS) that I am subject to backup withholding as a result of a failure to report all interest or dividends, or the IRS has notified me that I am no longer subject to backup withholding, and (3) I am a U.S. person (including a U.S.
resident alien), unless I have otherwise indicated in Section 3 above.

Certification instructions. You must cross out item
2 above if you have been notified by the IRS that you are currently subject to backup withholding because you have failed to report all interest and dividends on your tax return.

I understand that I will not be admitted as a stockholder until my investment has been accepted. Depositing of my check alone does not constitute
acceptance. The acceptance process includes, but is not limited to, reviewing the Subscription Agreement for completeness and signatures, conducting an Anti-Money Laundering check as required by the USA PATRIOT Act and depositing funds.

The IRS does not require your consent to any provision of this document other than the certifications required to avoid backup
withholding.
