To the Stockholders of Strategic Storage Growth Trust, Inc.:

You are cordially invited to attend a special meeting of stockholders of Strategic Storage Growth Trust, Inc., a Maryland corporation (“SSGT”), to be held on Friday, January 18, 2019, at 10:00 a.m., local time, at SSGT’s offices located at 10 Terrace Road, Ladera Ranch, California 92694.

At the special meeting, you will be asked to approve the merger (the “REIT Merger”) of SSGT with and into SST II Growth Acquisition, LLC, a Maryland limited liability company (“Merger Sub”), a wholly-owned subsidiary of Strategic Storage Trust II, Inc., a Maryland corporation (“SST II”), pursuant to the Agreement and Plan of Merger, dated as of October 1, 2018 (the “Merger Agreement”), among SSGT, SS Growth Operating Partnership, L.P., a Delaware limited partnership (“SSGT OP”), SST II, Strategic Storage Operating Partnership II, L.P. (“SST II OP”), and Merger Sub.

Upon completion of the REIT Merger, each share of SSGT common stock (consisting of our shares of Class A common stock and Class T common stock) will be converted into the right to receive an amount in cash equal to $12.00 per share, without interest and less any applicable withholding taxes, as more fully described in the enclosed proxy statement. Immediately after the REIT Merger, SSGT OP will merge with and into SST II OP (the “Partnership Merger,” and, together with the REIT Merger, the “Mergers”), with each unit of partnership interest in SSGT OP (an “OP Unit”) being converted automatically into 1.127 units of partnership interest in SST II OP.

Upon the unanimous recommendation of a special committee of our board of directors comprised solely of independent directors (the “SSGT special committee”), our board of directors unanimously (with H. Michael Schwartz, our Chairman and Chief Executive Officer, and Chairman and Chief Executive Officer of SST II, abstaining) authorized and approved the Merger Agreement, the REIT Merger, and the other transactions contemplated by the Merger Agreement, and declared that the Merger Agreement, the REIT Merger, and the other transactions contemplated by the Merger Agreement are advisable and in the best interests of SSGT and our stockholders.

Upon the unanimous recommendation of the SSGT special committee, our board of directors unanimously (with Mr. Schwartz abstaining) recommends you vote “FOR” the approval of the REIT Merger pursuant to the Merger Agreement at the special meeting.

Your vote is very important regardless of the number of shares that you own. The REIT Merger must be approved by the affirmative vote of holders of shares of our common stock entitled to cast a majority of the votes entitled to be cast on the matter at the special meeting. The proxy statement accompanying this letter provides you with more information concerning the special meeting, the Mergers, the Merger Agreement, and the other transactions contemplated by the Merger Agreement. We encourage you to read carefully the enclosed proxy statement, including the annexes accompanying the proxy statement. You may also obtain more information from us or from documents we have filed with the SEC.

Whether or not you plan to attend the special meeting, we request that you authorize a proxy to vote your shares by completing and returning the enclosed proxy card as promptly as possible or, if you prefer, by following the instructions on the enclosed proxy card for telephonic or Internet proxy authorization. If your shares are held in “street name” by your broker, bank or other nominee, you should instruct your broker, bank or other nominee on how to vote your shares using the voting instruction form that will be provided by your broker, bank or other nominee.

Thank you for your cooperation and continued support.

Very truly yours,

H. Michael Schwartz

Chairman of the Board of Directors and Chief Executive Officer

The accompanying proxy statement is dated November 26, 2018 and is first being mailed to our stockholders on or about November 29, 2018.

NOTICE OF SPECIAL MEETING OF STOCKHOLDERS

To Be Held on January 18, 2019

Dated November 26, 2018

Dear Stockholder:

You are cordially invited to attend a special meeting of stockholders of Strategic Storage Growth Trust, Inc., a Maryland corporation (“SSGT”), to be held on Friday, January 18, 2019, at 10:00 a.m., local time, at SSGT’s offices located at 10 Terrace Road, Ladera Ranch, California 92694. The special meeting is being held for the following purposes:

1. To approve the merger (the “REIT Merger”) of SSGT with and into SST II Growth Acquisition, LLC, a Maryland limited liability company (“Merger Sub”), a wholly-owned subsidiary of Strategic Storage Trust II, Inc., a Maryland corporation (“SST II”), pursuant to the Agreement and Plan of Merger, dated as of October 1, 2018 (the “Merger Agreement”), among SSGT, SS Growth Operating Partnership, L.P., a Delaware limited partnership (“SSGT OP”), SST II, Strategic Storage Operating Partnership II, L.P., a Delaware limited partnership (“SST II OP”), and Merger Sub;

2. To approve the adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the special meeting to approve the REIT Merger.

Only holders of record of shares of our common stock, par value $0.001 per share, at the close of business on November 26, 2018 will be entitled to notice of and to vote at the special meeting or any postponements or adjournments of the special meeting.

If you sign, date and return your proxy card without indicating how you wish to vote, your proxy will be voted in favor of the approval of the REIT Merger and the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies. If you fail to vote or submit your proxy, the effect will be that your shares of our common stock will not be counted for purposes of determining whether a quorum is present at the special meeting and will have the same effect as a vote against the approval of the REIT Merger but will not affect the vote regarding the adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies.

If you are a stockholder of record, you may revoke your proxy by following the procedures outlined in the accompanying proxy statement. If your shares are held in “street name,” then you may change your vote by submitting new voting instructions by contacting your broker, bank or other nominee.

By Order of the Board of Directors,

James L. Berg

Secretary

SUMMARY

This summary highlights selected information from this proxy statement and does not contain all of the information that may be important to you. Accordingly, you are urged to read this entire proxy statement carefully, including the annexes to this proxy statement and the other documents referenced in this proxy statement. Page references are included to direct you to a more complete description of the topics presented in this summary.

As used in this proxy statement, the terms “SSGT,” “we,” “our,” “us” and the “company” refer to Strategic Storage Growth Trust, Inc.; the term “SSGT OP” refers to SS Growth Operating Partnership, L.P.; the term “SST II” refers to Strategic Storage Trust II, Inc.; the term “SST II OP” refers to Strategic Storage Operating Partnership II, L.P.; the term “Merger Sub” refers to SST II Growth Acquisition, LLC; and the term “common stock” refers to shares of our Class A common stock, par value $0.001 per share, and our Class T common stock, par value $0.001 per share.

The Parties to the Mergers (page 18)

• Strategic Storage Growth Trust, Inc. We are an externally-managed real estate investment trust (“REIT”) formed as a Maryland corporation on March 12, 2013, to own, operate, acquire, develop and redevelop self storage facilities located throughout the United States and Canada. We are anon-traded REIT sponsored by SmartStop Asset Management, LLC (“SmartStop”).

• SS Growth Operating Partnership, L.P. SSGT OP is a Delaware limited partnership through which we conduct substantially all of our business and own, either directly or indirectly through subsidiaries, substantially all of our assets.

• Strategic Storage Trust II, Inc. SST II is an externally-managed REIT formed as a Maryland corporation on January 8, 2013, to own, operate, and acquire self storage facilities located throughout the United States and Canada. Like us, SST II is anon-traded REIT also sponsored by SmartStop.

• Strategic Storage Operating Partnership II, L.P. SST II OP is a Delaware limited partnership and a subsidiary of SST II. Substantially all of SST II’s assets are owned, directly or indirectly, and substantially all of SST II’s operations are conducted, directly or indirectly, by SST II OP.

• SST II Growth Acquisition, LLC. Merger Sub is a Maryland limited liability company and a wholly-owned subsidiary of SST II. Merger Sub was formed by SST II in connection with the REIT Merger (as defined below).

The Proposals

• The REIT Merger (Proposal 1). You will be asked to consider and vote upon the proposal to approve the merger (the “REIT Merger”) of SSGT with and into Merger Sub, a subsidiary of SST II, pursuant to an Agreement and Plan of Merger, dated as of October 1, 2018 (as it may be amended from time to time, the “Merger Agreement”), by and among SSGT, SSGT OP, SST II, SST II OP, and Merger Sub.

• Adjournment (Proposal 2). You will also be asked to approve a proposal that will give us authority to adjourn the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies in favor of the proposal to approve the REIT Merger pursuant to the Merger Agreement, if there are not sufficient votes at the time of the special meeting to approve the REIT Merger.

The Special Meeting (page 15)

• Date, Time, Place and Purpose. The special meeting will be held on Friday, January 18, 2019, at 10:00 a.m., local time, at SSGT’s offices located at 10 Terrace Road, Ladera Ranch, California 92694.

• Record Date. If you owned shares of our common stock at the close of business on November 26, 2018, which is the record date for the special meeting, you are entitled to notice of and to vote at the special meeting. Except as described below with respect to shares held by our advisor, SS Growth Advisor, LLC (our “Advisor”), our directors, and their affiliates, you have one vote on each proposal presented at the special meeting for each share of our common stock that you owned at the close of business on the record date. Each fractional share of our common stock outstanding on the record date is entitled to a commensurate fractional vote on each proposal presented at the special meeting. Notwithstanding the foregoing, due to the related party nature of the proposed transaction, shares owned by our Advisor, our directors, and their affiliates will not be voted on the proposal to approve the REIT Merger and will not be included in determining the requisite percentage of shares necessary to approve the REIT Merger.

• Quorum. The presence at the special meeting, in person or by proxy, of holders of record of a majority of the shares of our common stock outstanding at the close of business on the record date and entitled to vote will constitute a quorum, permitting us to conduct our business at the special meeting. As of November 26, 2018, there were 26,706,924 shares of our common stock outstanding.

• Vote Required. Approval of the REIT Merger pursuant to the Merger Agreement requires the affirmative vote of holders of shares of our common stock entitled to cast a majority of the votes entitled to be cast on the matter at the special meeting. Approval of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies requires the affirmative vote of not less than a majority of the votes cast on such matter.

The Mergers, Consideration and Other Material Matters

• The REIT Merger (page 19). At the effective time of the REIT Merger (the “effective time”), we will be merged with and into Merger Sub. As a result of the REIT Merger, Merger Sub will be the surviving company of the REIT Merger, and we will cease to exist as a separate public reporting company.

• The Partnership Merger (page 44). Immediately after the REIT Merger, SSGT OP will be merged with and into SST II OP (the “Partnership Merger,” and, together with the REIT Merger, the “Mergers”). As a result of the Partnership Merger, SST II OP will be the surviving partnership.

• Consideration to be Received in the Mergers (page 45).Upon completion of the REIT Merger, our stockholders will be entitled to receive an amount in cash equal to $12.00 per share of our common stock, without interest and less any applicable withholding taxes. Upon completion of the Partnership Merger, each outstanding unit of partnership interest in SSGT OP (the “OP Units”) will be converted automatically into 1.127 units of partnership interest in SST II OP. If we or SSGT OP split, combine, or otherwise reclassify our common stock or the OP Units, make a dividend or other distribution in shares of our common stock or the OP Units (other than shares of our common stock issued pursuant to our distribution reinvestment plan), or engage in a reclassification, recapitalization, or other similar transaction, the consideration payable to holders of our common stock or the OP Units, as applicable, will be appropriately and proportionately adjusted to provide such holders the same economic effect as contemplated by the Merger Agreement prior to such change. The consideration to be received by our stockholders and the holders of OP Units in connection with the Mergers represents a total purchase price of approximately $350 million, which includes outstanding debt to be assumed or repaid by SST II as of November 15, 2018, but excludes transaction costs.

2

• Treatment of SSGT Restricted Stock (page 45). Each share of our common stock that is subject to vesting or other lapse restrictions (the “restricted stock”) that is outstanding immediately prior to the effective time will, as of the effective time, become fully vested and be converted into the right to receive an amount of cash equal to the merger consideration of $12.00 per share, without interest and less any applicable withholding taxes. Additionally, each holder of restricted stock will receive in cash an amount equal to all accrued but unpaid dividends on the shares of restricted stock owed to each such holder.

• Dividends (page 48). During the term of the Merger Agreement, we are permitted to continue paying holders of our common stock regular cash dividends, declared quarterly in advance, paid monthly and accrued daily until the closing of the REIT Merger, in accordance with past practice at a rate not to exceed the daily rate of $0.0013698630 per share (which equates to an annual rate of $0.50 per share).

• Recommendation of Our Board of Directors (page 26). Upon the unanimous recommendation of a special committee of our board of directors, which committee was comprised solely of independent directors (the “SSGT special committee”), our board of directors unanimously (with Mr. Schwartz abstaining) authorized and approved the Merger Agreement, the REIT Merger, and the other transactions contemplated by the Merger Agreement, and declared that the Merger Agreement, the REIT Merger, and the other transactions contemplated by the Merger Agreement are fair and reasonable, both financially and otherwise, to the company and advisable and in the best interests of the company and our stockholders. Accordingly, upon the unanimous recommendation of the SSGT special committee, our board of directors unanimously (with Mr. Schwartz abstaining) recommends you vote “FOR” the approval of the REIT Merger pursuant to the Merger Agreement at the special meeting. See “Reasons for the REIT Merger and Recommendation of Our Board of Directors” on page 26 for a discussion of the material factors, risks and countervailing factors considered by our board of directors and the SSGT special committee in making their respective recommendations.

• Opinion of Our Financial Advisor (page 29). KeyBanc Capital Markets Inc. (“KeyBanc”) delivered its opinion to the SSGT special committee, and at its direction, our board of directors that, as of October 1, 2018 and based upon and subject to the matters described in the written opinion, the consideration to be paid pursuant to the Merger Agreement was fair, from a financial point of view, to the holders of shares of SSGT common stock other than SST II, Merger Sub, SmartStop, and their respective affiliates (the “unaffiliated holders”).

The full text of KeyBanc’s written opinion, dated October 1, 2018, is attached to this proxy statement as Annex B. You should read KeyBanc’s opinion carefully and in its entirety for a discussion of, among other things, the scope of the review undertaken and the assumptions made, procedures followed, matters considered and qualifications and limitations upon the review undertaken by KeyBanc in connection with its opinion. This summary is qualified in its entirety by reference to the full text of the opinion. KeyBanc’s opinion was prepared for the use of the SSGT special committee and the SSGT board of directors, and addressed only the fairness from a financial point of view, as of the date of the opinion, of the consideration to be paid to the unaffiliated holders pursuant to theMerger Agreement. It does not constitute a recommendation as to how any stockholder should vote with respect to the REIT Merger or any other matter, and does not in any manner address the price at which shares of SSGT common stock will trade at any time, if ever.

For more information regarding KeyBanc and KeyBanc’s opinion, see “The REIT Merger—Opinion of Our Financial Advisor.”

• Conditions to Completion of the Mergers (page 55). Completion of the Mergers is subject to satisfaction or waiver of a number of conditions, including, among others, the approval of the REIT Merger by our stockholders, the accuracy of the representations and warranties made by the parties in

3

the Merger Agreement, the performance of the parties’ obligations under the Merger Agreement, and the absence of any material adverse effect on us, as defined in the Merger Agreement.

• Completion of the Mergers (page 44). We anticipate completing the Mergers promptly after the REIT Merger is approved by our stockholders, subject to satisfaction of the other conditions in the Merger Agreement.

• No Solicitation of Transactions by SSGT (page 51). The Merger Agreement restricts our ability to solicit other acquisition proposals, or to provide information to or engage in discussions with third parties regarding other acquisition proposals. However, under the terms of the Merger Agreement, we were permitted, for a period of 45 days following the signing of the Merger Agreement (the “go shop period”), to initiate, solicit, provide information, and enter into discussions concerning proposals relating to alternative business combination transactions, subject to the potential payment of a $2.9 million termination fee. Upon expiration of the go shop period, we had not received an alternative acquisition proposal nor were we negotiating with any prospective buyer. Following expiration of the go shop period, our board of directors is permitted to change its recommendation with respect to the REIT Merger in response to a superior proposal and, upon payment of a $9.6 million termination fee, we are permitted to terminate the Merger Agreement and enter into an agreement with respect to a superior proposal.

• Termination of the Merger Agreement (page 57). The Merger Agreement may be terminated in certain circumstances prior to the completion of the REIT Merger. These circumstances include, among others and subject to the requirements for termination in the Merger Agreement:

• by mutual written consent of SST II and us;

• by either SST II or us if:

• the REIT Merger has not been consummated on or before April 1, 2019 (so long as the terminating party is not at fault);

• there is a final,non-appealable order or injunction prohibiting the Mergers (so long as such order or injunction is not the result of the terminating party’s failure to satisfy its obligations under the Merger Agreement);

• our stockholders fail to approve the REIT Merger (so long as the failure to obtain stockholder approval was not due to an action or the failure to act on our part that constitutes a material breach of any of our obligations under the Merger Agreement).

• by SST II, if:

• we breach or fail to perform any of our representations, warranties, covenants, or other agreements set forth in the Merger Agreement which would, or would reasonably be expected to, result in a failure of SST II’s conditions to consummation of the Mergers and we do not cure such breach within a specified period; or

• our board of directors changes its recommendation of the REIT Merger in a manner adverse to SST II or recommends any other acquisition proposal, we fail to include in this proxy statement our board of directors’ recommendation in favor of approval of the REIT Merger, or our board of directors otherwise enters into an agreement with respect to any other acquisition proposal in breach of the Merger Agreement; and

• by us, if:

• SST II breaches or fails to perform any of its representations, warranties, covenants, or other agreements set forth in the Merger Agreement which would, or would reasonably be expected to, result in a failure of our conditions to consummation of the Mergers and SST II does not cure such breach within a specified period;

4

• prior to our stockholders approving the REIT Merger, a certain development or change in circumstances occurs (an “intervening event”) and our board of directors determines that the failure to terminate the Merger Agreement would be inconsistent with their duties under applicable law, provided that we concurrently pay a $9.6 million termination fee; or

• we accept a superior proposal in compliance with the Merger Agreement and enter into a definitive agreement with respect to the superior proposal, provided that we concurrently pay a $9.6 million termination fee.

• Termination Fees (page 59). We are required to pay a termination fee of $9.6 million if the Merger Agreement is terminated under certain circumstances, including, among others, termination by us as a result of an intervening event or our acceptance of a superior proposal in compliance with the Merger Agreement and entry into a definitive agreement with respect to such superior proposal. The Merger Agreement also provides that SST II is required to pay us a reverse termination fee of $9.6 million under specified circumstances related to the failure by SST II to consummate the closing.

• Expense Reimbursement (page 59). Generally, all fees and expenses incurred in connection with the REIT Merger and the other transactions contemplated by the Merger Agreement will be paid by the party incurring those expenses. However, we and SST II may be obligated to pay the other party an amount up to $2 million in expense reimbursements if the Merger Agreement is terminated under certain circumstances.

• Interests of Certain Persons in the Mergers (page 42). Our directors and executive officers have interests in the Mergers that may be different from, or in addition to, the interests of our stockholders generally. These interests include, among others, a disposition fee payable in connection with the Mergers, a distribution for redemption of a special limited partner interest in connection with the Mergers, beneficial ownership of OP Units, and the vesting of shares of restricted stock. In addition, as we and SST II are bothnon-traded REITs sponsored by SmartStop, most of our executive officers are also executive officers of SST II and one of our directors is also a director of SST II. Our board of directors and the SSGT special committee were aware of these interests and considered them, among other matters, in reaching their respective decisions to approve the REIT Merger pursuant to the Merger Agreement.

• Financing and SST II Stockholder Approval (page 37). The transaction value of the Mergers is approximately $350 million, which includes outstanding debt to be assumed or repaid by SST II as of November 15, 2018, but excludes transaction costs. We understand from SST II that it is in the process of negotiating new loans in order to finance the Mergers, which would include the financing of our properties, the refinancing of certain of SST II’s existing properties, and the payoff of certain of SST II’s existing loans. The consummation of the Mergers is not subject to any financing condition or SST II stockholder approval.

• Deregistration of Our Common Stock (page 37). If the REIT Merger is completed, our common stock will be deregistered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

• Material United States Federal Income Tax Consequences (page 37). The receipt of the merger consideration for each share of our common stock pursuant to the REIT Merger will be a taxable transaction for U.S. federal income tax purposes. Generally for U.S. federal income tax purposes, you will recognize gain or loss as a result of the REIT Merger measured by the difference, if any, between the merger consideration per share and your adjusted tax basis in that share. In addition, under certain circumstances, we may be required to withhold a portion of your merger consideration under applicable tax laws, including pursuant to the Foreign Investment in Real Property Tax Act of 1980 (“FIRPTA”) and Foreign Account Tax Compliance Act (“FATCA”). Tax matters can be complicated, and the tax consequences of the REIT Merger to you will depend on your particular tax situation. We encourage you to consult your tax advisor regarding the tax consequences of the REIT Merger to you.

5

• No Appraisal or Dissenters’ Rights (page 62). As permitted by Maryland General Corporation Law (“MGCL”), our charter provides that stockholders are not entitled to exercise any appraisal rights unless our board of directors, upon the affirmative vote of a majority of the board of directors, determines that such rights apply. Because our board of directors has not made such a determination, our stockholders are not entitled to exercise any appraisal rights in connection with the REIT Merger or any other transactions contemplated by the Merger Agreement.

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING AND THE MERGERS

The following questions and answers address briefly some questions you may have regarding the special meeting and the Mergers. These questions and answers do not address all questions that may be important to you. Accordingly, we urge you to read this entire proxy statement carefully, including the annexes to this proxy statement and the other documents to which we have referred you.

Q: Why am I receiving this proxy statement?

A: You are receiving this proxy statement and the accompanying proxy card because at the close of business on November 26, 2018, the record date for the special meeting, you owned shares of our common stock. This proxy statement contains information related to the solicitation of proxies for use at the special meeting of stockholders, to be held at 10:00 a.m., local time, on Friday, January 18, 2019 at our offices located at 10 Terrace Road, Ladera Ranch, California 92694, for the purposes stated in the accompanying Notice of Special Meeting of Stockholders. This solicitation is made by our board of directors on our behalf.

Q: What will I be voting on at the special meeting?

A: You will be asked to vote on the following proposals:

• to approve the REIT Merger pursuant to the Merger Agreement; and

• to approve adjournments of the special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the special meeting to approve the REIT Merger.

Q: Will any other items of business come before the special meeting?

A: No. As permitted by Maryland law, our bylaws require that any matter to be considered at the special meeting must be described in the Notice of Special Meeting of Stockholders. As such, the only items of business to come before the special meeting are those proposals described in the Notice of Special Meeting of Stockholders.

Q: What is the proposed transaction?

A: The proposed transaction is the acquisition of SSGT by SST II pursuant to the Merger Agreement. The proposed transaction will be effected by two different transactions. First, we will merge with and into Merger Sub, following which Merger Sub will continue as the surviving company, and we will cease to exist as a separate public reporting company. Second, immediately after the completion of the REIT Merger, SSGT OP will merge with and into SST II OP, following which SST II OP will continue as the surviving entity. For additional information about the Mergers, please review the Merger Agreement attached to this proxy statement as Annex A and incorporated by reference into this proxy statement. We encourage you to read the Merger Agreement carefully and in its entirety, as it is the principal document governing the Mergers.

Q: What effects will the REIT Merger have on us?

A: As a result of the REIT Merger, we will cease to be a public reporting company and our assets will be indirectly wholly-owned by SST II. Following the consummation of the REIT Merger, our common stock will be deregistered under the Exchange Act, and we will no longer file reports with the SEC.

Q: What will I receive in the REIT Merger if it is completed?

A: Upon completion of the REIT Merger, our stockholders will be entitled to receive an amount in cash equal to $12.00 per share of our common stock, without interest and less any applicable withholding taxes. If we

7

split, combine, or otherwise reclassify our securities, pay distributions in stock (other than common stock issued pursuant to our distribution reinvestment plan), or engage in a reclassification, recapitalization, or other similar transaction, the consideration payable to holders of our common stock will be adjusted by an amount required to provide such holders the same economic effect as contemplated by the Merger Agreement prior to such change. The consideration to be received by our stockholders and the holders of OP Units in connection with the Mergers represents a total purchase price of approximately $350 million, which includes outstanding debt to be assumed or repaid by SST II as of November 15, 2018, but excludes transaction costs.

Q: Will I receive my regular dividends with respect to the common stock that I own?

A: Yes. On September 26, 2018, our board of directors authorized a distribution rate for the fourth quarter of 2018 of $0.0013698630 per day per share on the outstanding shares of our common stock payable to stockholders of record of such shares as shown on our books at the close of business on each day during the period, commencing on October 1, 2018 and continuing on each day thereafter through and including December 31, 2018. Pursuant to the Merger Agreement, through the effective time of the REIT Merger, we are permitted to continue paying holders of our common stock regular cash dividends in accordance with past practice at a rate not to exceed the daily rate of $0.0013698630 (which equates to an annual rate of $0.50 per share).

Q: Will I have to pay taxes on the merger consideration I receive?

A: Yes. The receipt of the merger consideration for each share of our common stock pursuant to the REIT Merger will be a taxable transaction for U.S. federal income tax purposes. Generally, for U.S. federal income tax purposes, you will recognize gain or loss as a result of the REIT Merger measured by the difference, if any, between the merger consideration per share and your adjusted tax basis in that share of our common stock. In addition, under certain circumstances, we may be required to withhold a portion of your merger consideration under applicable tax laws, including FIRPTA and FATCA. See “Material United States Federal Income Tax Consequences” for a more complete discussion of the U.S. federal income tax consequences of the REIT Merger. Tax matters can be complicated, and the tax consequences of the REIT Merger to you will depend on your particular tax situation. We encourage you to consult your tax advisor regarding the tax consequences of the REIT Merger to you.

Q: When do you expect the Mergers to be completed?

A: We are working to complete the Mergers as soon as possible. If our stockholders approve the REIT Merger at the special meeting, and assuming that the other conditions to the Mergers are satisfied or waived, we anticipate that the Mergers will become effective promptly after the special meeting.

Q: If the Mergers are completed, when can I expect to receive payment?

A: After the Mergers are completed, SST II will arrange, via its paying agent, to send a letter of transmittal to stockholders. Holders of book-entry shares will automatically, upon the effective time and without any further action by such stockholder, be entitled to receive the merger consideration due to such stockholder.

Q: What happens if the Mergers are not consummated?

A: If the REIT Merger is not approved by our stockholders, or if the Mergers are not consummated for any other reason, our stockholders will not receive any payment for their shares in connection with the REIT Merger. Instead, we will remain a public reporting company. Under specified circumstances, we may be required to pay SST II a termination fee of $9.6 million, or SST II may be required to pay us a reverse termination fee of $9.6 million. We or SST II may also be required to pay to the other party an expense reimbursement of up to $2.0 million under certain circumstances. See “The Merger Agreement—Termination of the Merger Agreement—Termination Fees and Expense Reimbursement.”

Q: When and where is the special meeting?

A: The special meeting will take place at 10:00 a.m., local time, on Friday, January 18, 2019 at our offices located at 10 Terrace Road, Ladera Ranch, California 92694.

Q: Who can vote at the special meeting?

A: Except as described below with respect to shares held by our Advisor, our directors, and their affiliates, holders of record of shares of our common stock as of the close of business on November 26, 2018, which is the record date for the special meeting, are entitled to receive notice of and to vote at the special meeting. Our common stock (consisting of both Class A shares and Class T shares) is the only class of securities entitled to vote at the special meeting. Notwithstanding the foregoing, due to the related party nature of the proposed transaction, shares owned by our Advisor, our directors, and their affiliates will not be voted on the proposal to approve the REIT Merger and will not be included in determining the requisite percentage of shares necessary to approve the REIT Merger.

Q: Who can attend the special meeting?

A: You can attend the special meeting if you are a record or beneficial holder of shares of our common stock at the close of business on the record date, or a duly appointed proxy. You will need to present proof of share ownership and valid picture identification, such as a driver’s license or passport, before being admitted. If your shares are held beneficially in the name of a bank, broker or other nominee (i.e., in “street name”), you must present proof of ownership by presenting a bank or brokerage account statement reflecting your share ownership as of the record date.

Q: How many votes do I have?

A: Except as described above with respect to shares held by our Advisor, our directors, and their affiliates, you have one vote on each proposal presented at the special meeting for each share of our common stock that you owned on the record date. Each fractional share of our common stock outstanding on the record date is entitled to a commensurate fractional vote on each proposal presented at the special meeting.

Q: What will constitute a quorum at the special meeting?

A: The presence at the special meeting, in person or by proxy, of the holders of a majority of the shares of our common stock outstanding at the close of business on the record date and entitled to vote will constitute a quorum for the conduct of business at the special meeting. We will include abstentions, if any, in the calculation of the number of shares considered to be present at the meeting for purposes of determining the presence of a quorum. There can be no “brokernon-votes” at the special meeting, so failure to provide instructions to your broker, bank, or other nominee on how to vote will result in your shares not being counted as present at the meeting. A “brokernon-vote” occurs when shares held by a broker, bank, or other nominee are represented at the meeting, but the broker, bank, or other nominee has not received voting instructions from the beneficial owner and does not have the discretion to direct the voting of the shares on a particular proposal but has discretionary voting power on other proposals. The only proposals to be voted on at the special meeting are regarded as“non-routine” matters, meaning that your broker, bank, or other nominee may not vote on these proposals without instructions from you.

As of the record date, there were 26,706,924 shares of our common stock outstanding. Approximately 13,350,000 shares of our common stock must be represented at the special meeting to obtain a quorum on each proposal.

Q: What vote is required to approve the REIT Merger?

A: Approval of the REIT Merger requires the affirmative vote of holders of shares of our common stock entitled to cast a majority of the votes entitled to be cast on the matter at the special meeting. Except as

9

described above with respect to shares held by our Advisor, our directors, and their affiliates, each share of our common stock that was outstanding on the record date entitles the holder to one vote on each proposal presented at the special meeting. Each fractional share of our common stock outstanding on the record date is entitled to a commensurate fractional vote on each proposal presented at the special meeting. Because the required vote for this proposal is based on the number of outstanding shares of our common stock entitled to vote at the special meeting, rather than the number of votes cast, failure to vote your shares, abstentions, and a failure to provide instructions to your broker, bank, or other nominee with respect to this proposal will have the same effect as voting against approval of the REIT Merger.

Q: What vote is required to approve the proposal to adjourn the special meeting?

A: Approval of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies requires the affirmative vote of not less than a majority of the votes cast on the matter. If you fail to vote your shares or abstain from voting with respect to this proposal, or if you fail to provide instructions to your broker, bank or other nominee with respect to this proposal, your failure to vote will not have any effect on the outcome, assuming a quorum is present.

Q: How does the board of directors recommend that I vote?

A: Upon the recommendation of the SSGT special committee, our board of directors has unanimously (with Mr. Schwartz abstaining) authorized and approved the Merger Agreement, the REIT Merger, and the other transactions contemplated by the Merger Agreement, and declared that the Merger Agreement, the REIT Merger, and the other transactions contemplated by the Merger Agreement are fair and reasonable, both financially and otherwise, to the company and advisable and in the best interests of the company and our stockholders. Accordingly, our board of directors unanimously (with Mr. Schwartz abstaining) recommends you vote “FOR” the approval of the REIT Merger at the special meeting. Please see “The REIT Merger—Reasons for the REIT Merger and Recommendation of Our Board of Directors” on page 26 for a discussion of the material factors, risks and countervailing factors considered by our board of directors in making its recommendation. Our board of directors also recommends that you vote “FOR” the proposal to approve the adjournment of the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies.

Q: How do I cast my vote?

A: If you hold your shares of our common stock directly, you may vote in person at the special meeting or submit a proxy by completing, signing, dating and returning the enclosed proxy card in the accompanyingpre-addressed, postage paid envelope, or, if you prefer, you can submit voting instructions via telephonic or Internet proxy authorization by following the instructions on the enclosed proxy card.

Q: How do I cast my vote if my shares of common stock are held in “street name” through a broker, bank or other nominee?

A: If you hold your shares of our common stock in “street name” through a broker, bank, or other nominee, your broker, bank or other nominee will not vote your shares unless you provide instructions on how to vote. You must obtain a voting instruction form from the broker, bank, or other nominee that is the record holder of your shares and provide the broker, bank, or other nominee with instructions on how to vote your shares. Your broker, bank, or other nominee may not vote on the proposals without instructions from you. Failure to provide instructions to your broker, bank, or other nominee on how to vote will result in your shares not being counted as present at the special meeting. If you hold your shares of our common stock in “street name” through a broker, bank or other nominee, you may also vote in person at the special meeting if you bring acceptable proof of ownership, such as a letter from your broker or an account statement showing that you beneficially owned shares on the record date.

10

Q: What will happen if I fail to vote or abstain from voting?

A: If you fail to cast your vote in person or by proxy, or if you hold your shares of our common stock in “street name” through a broker, bank or other nominee and fail to give voting instructions to the record holder of your shares, or if you abstain from voting, it will have the same effect as a vote against the proposal to approve the REIT Merger.

If you fail to cast your vote in person or by proxy, or if you hold your shares of our common stock in “street name” through a broker, bank or other nominee and fail to give voting instructions to the record holder of your shares, or if you abstain from voting, it will not have any effect on the outcome of the proposal to approve any adjournments of the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies, assuming a quorum is present.

Q: How will proxy cards be voted?

A: If you properly submit a proxy card prior to the special meeting, or you properly submit a proxy via telephonic or Internet proxy authorization, your shares will be voted as you direct. If you properly submit a proxy card prior to the special meeting, but do not indicate how to vote your shares, your shares will be voted “FOR” the approval of the REIT Merger and “FOR” the proposal to approve any adjournments of the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies.

Q: What happens if I sell my shares before the special meeting?

A: If you hold shares of our common stock at the close of business on the record date but transfer these shares prior to the special meeting, you will retain your right to vote at the special meeting, but not the right to receive the merger consideration. Only a person who holds shares of our common stock at the effective time of the REIT Merger is entitled to receive the merger consideration.

Q: Can I change my vote?

A: Yes. You may change or revoke a previously granted proxy at any time before it is exercised by either:

• submitting a later-dated proxy card, in person at the special meeting or by mail, or otherwise submitting a new proxy via telephonic or Internet proxy authorization; or

• delivering instructions to us at our executive offices by writing to Strategic Storage Growth Trust, Inc., Attention: James L. Berg, 10 Terrace Road, Ladera Ranch, California 92694.

To be effective, a proxy revocation must be received by us at or prior to the special meeting. Attendance at the special meeting will not, in itself, constitute revocation of a previously granted proxy.

If your shares are held in “street name,” then you may change your vote by submitting new voting instructions by contacting your broker, bank or other nominee. You may also vote in person at the special meeting if you bring acceptable proof of ownership, such as a letter from your broker or an account statement showing that you beneficially owned shares on the record date.

Q: Should I send in my share certificates now?

A: No. Shortly after the Mergers are completed, SST II will arrange to send a letter of transmittal to stockholders whose shares are certificated. Payments and exchanges will be made to stockholders upon submission of the letter of transmittal, properly endorsed share certificates, if applicable, and other documentation that may be required. You should use the letter of transmittal to exchange share or unit certificates for the merger consideration to which you are entitled as a result of the Mergers. DO NOT SEND ANY CERTIFICATES WITH YOUR PROXY.

11

Q: What if my shares are uncertificated?

A: For those holders of record of uncertificated shares of our common stock or represented by book-entry positions (the “Book-Entry Shares”), as soon as reasonably practicable following the effective time, such Book-Entry Shares will be converted into the merger consideration and reflected as such in the account where your shares are held. SST II will arrange to send you your merger consideration in respect of your shares of our common stock.

Q: Are stockholders entitled to appraisal rights?

A: As permitted by the MGCL, our charter provides that stockholders are not entitled to exercise any appraisal rights unless our board of directors, upon the affirmative vote of a majority of the board of directors, determines that such rights may be exercised. Because our board of directors has not made such a determination, our stockholders are not entitled to exercise any appraisal rights. For more information, see “No Appraisal or Dissenters’ Rights” on page 62 of this proxy statement.

Q: Where can I find more information about the company?

A: We file certain information with the SEC. This information is available at the Internet site the SEC maintains at http://www.sec.gov and on our website at http://www.strategicreit.com. Information contained on our website is not part of, or incorporated by reference in, this proxy statement. You can also request copies of these documents from us. See “Where You Can Find More Information” on page 62.

Q: Who will solicit and pay the cost of soliciting proxies?

A: We will bear the cost of soliciting proxies for the special meeting. Our board of directors is soliciting your proxy on our behalf. Our directors and officers and employees of SmartStop may solicit proxies by telephone and facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies. We have also retained Mediant, Inc. (“Mediant”) to assist us in the solicitation of proxies, and have agreed to pay them approximately $28,000, plus reimbursement ofout-of-pocket expenses, for their services. We also expect to incur approximately $14,000 in expenses related to printing of these proxy materials. We will also request that banking institutions, brokerage firms, custodians, directors, nominees, fiduciaries and other like parties forward the solicitation materials to the beneficial owners of shares of our common stock held of record by such persons, and we will, upon request of such persons, reimburse forwarding charges andout-of-pocket expenses.

Q: What is “householding” and how does it affect me?

A: The SEC has adopted a rule concerning the delivery of documents filed by us with the SEC, including proxy statements, which allows us to send a single proxy statement to any household at which two or more stockholders reside if they share the same last name or we reasonably believe they are members of the same family. This procedure is referred to as “householding.” This rule benefits both you and us. It reduces the volume of duplicate information received at your household and helps us reduce expenses. Each stockholder subject to householding will continue to receive a separate proxy card or voting instruction card.

We will promptly deliver, upon written or oral request, a separate copy of this proxy statement to a stockholder at a shared address to which a single copy was previously delivered. If you received a single copy of this proxy statement, but you would prefer to receive your own copy, you may direct requests for separate copies to Strategic Storage Growth Trust, Inc., Attention: James L. Berg, 10 Terrace Road, Ladera Ranch, California 92694 or call us at (877)327-3485. Also, if your household currently receives multiple copies of disclosure documents and you would like to receive just one set, please contact us at the same address and phone number.

12

Q: Who can help answer my other questions?

A: If you have more questions about the special meeting or the Mergers, you should contact James L. Berg, our Secretary, as follows:

Strategic Storage Growth Trust, Inc.

Ladera Ranch, California 92694

THE SPECIAL MEETING

Date, Time and Place of the Special Meeting

This proxy statement is being furnished to our stockholders in connection with the solicitation of proxies by our board of directors for use at a special meeting to be held on Friday, January 18, 2019 at 10:00 a.m., local time. The special meeting will take place at our offices located at 10 Terrace Road, Ladera Ranch, California 92694.

Purpose

The purpose of the special meeting is for you to consider and vote upon the following proposals:

• to approve the REIT Merger pursuant to the Merger Agreement; and

• to approve any adjournments of the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies if there are not sufficient votes at the time of the special meeting to approve the REIT Merger.

Our stockholders must approve the REIT Merger for the REIT Merger to occur. A copy of the Merger Agreement is attached as Annex A to this proxy statement, which we encourage you to read carefully in its entirety. Please see “The Merger Agreement” on page 44 below for a summary of the material provisions of the Merger Agreement.

Record Date, Notice and Quorum

Only holders of shares of our common stock at the close of business on November 26, 2018, which is the record date for the special meeting, are entitled to receive notice of and vote at the special meeting or any postponements or adjournments of the special meeting. On the record date, there were 26,706,924 shares of our common stock outstanding.

The presence at the special meeting, represented in person or by proxy, of holders of a majority of our outstanding common stock at the close of business on the record date and entitled to vote will constitute a quorum for conduct of business at the special meeting. A quorum is necessary to hold the special meeting. Any shares of our common stock held by any of our subsidiaries are not considered to be outstanding for purposes of determining a quorum. In addition, due to the related party nature of the proposed transaction, shares owned by our Advisor, our directors, and their affiliates will not be voted on the proposal to approve the REIT Merger and will not be included in determining the requisite percentage of shares necessary to approve the REIT Merger. Abstentions will be counted as shares present for the purposes of determining a quorum.

Required Vote

Approval of the REIT Merger requires the affirmative vote of holders of shares of our common stock entitled to cast a majority of the votes entitled to be cast on the matter at the special meeting. Except as described above with respect to shares held by our Advisor, our directors, and their affiliates, each share of our common stock that was outstanding on the record date entitles the holder to one vote on each proposal presented at the special meeting. Each fractional share of our common stock outstanding on the record date is entitled to a commensurate fractional vote on each proposal presented at the special meeting. Because the required vote for this proposal is based on the number of outstanding shares of our common stock rather than on the number of votes cast, failure to vote the shares of our common stock that you own (including as a result of failing to provide instructions to your broker, bank or other nominee) and abstentions will have the same effect as voting against approval of the REIT Merger.

15

The proposal to approve any adjournments of the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies requires the affirmative vote of holders of a majority of the votes cast on the matter. For this proposal, if you abstain from voting or fail to vote shares of our common stock that you own, or if you fail to provide instructions to your broker, bank or other nominee, such failure will not have any effect on the outcome of the proposal, assuming a quorum is present.

Voting by our Directors and Executive Officers

As of the record date, our directors and executive officers owned an aggregate of approximately 6,900 shares of our common stock, representing approximately 0.03% of the shares of our common stock outstanding on that date. Due to the related party nature of the proposed transaction, shares owned by our Advisor, our directors, and their affiliates will not be voted on the proposal to approve the REIT Merger and will not be included in determining the requisite percentage of shares necessary to approve the REIT Merger.

Voting

Stockholders of record may cause their shares of our common stock to be voted using one of the following methods:

• mark, sign, date and return the enclosed proxy card by mail;

• submit your proxy or voting instructions by telephone or by Internet by following the instructions included with your proxy card; or

• appear and vote in person by ballot at the special meeting.

Regardless of whether you plan to attend the special meeting, we request that you complete and return your proxy as promptly as possible. If you own shares through a broker, bank or other nominee (i.e., in “street name”), you must provide voting instructions in accordance with the instructions on the voting instruction card that your broker, bank or other nominee provides to you. You should instruct your broker, bank or other nominee as to how to vote your shares, following the directions contained in such voting instruction card. If you have not received such voting instructions or require further information regarding such voting instructions, contact your broker, bank or other nominee who can give you directions on how to vote your shares.

Proxies and Revocation

If you submit a proxy, your shares will be voted at the special meeting as you indicate on your proxy. If no instructions are indicated on your signed proxy card, your shares will be voted “FOR” approval of the REIT Merger and “FOR” approval of the proposal to adjourn the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies.

You may revoke your proxy at any time, but only before the proxy is voted at the special meeting, in any of three ways:

• submitting a later-dated proxy, in person at the special meeting or by mail, or submitting your proxy or voting instructions by telephone or by Internet at a date after the date of the previously submitted proxy relating to the same shares;

• delivering instructions to our Secretary in writing at our executive offices located at: Strategic Storage Growth Trust, Inc., Attention: James L. Berg, 10 Terrace Road, Ladera Ranch, California 92694; or

• by attending the special meeting and voting in person by ballot.

Attendance at the special meeting will not, in itself, constitute revocation of a previously granted proxy. If you own your shares in “street name,” you may revoke or change previously delivered voting instructions by following the instructions provided by the broker, bank or other nominee that is the registered owner of shares of our common stock.

16

You will only be asked to approve the REIT Merger pursuant to the Merger Agreement, and any adjournments of the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies. No additional matters will be brought before the special meeting.

We will pay the costs of soliciting proxies for the special meeting. Our directors and officers and employees of SmartStop may solicit proxies by telephone and facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies. We have retained Mediant to assist us in the solicitation of proxies, and will pay fees of approximately $28,000, plus reimbursement ofout-of-pocket expenses, to Mediant for its services. We also expect to incur approximately $6,600 in expenses related to printing of these proxy materials. In addition, our arrangement with Mediant includes provisions obligating us to indemnify it for certain liabilities that could arise in connection with its solicitation of proxies on our behalf. We will also request that individuals and entities holding shares of our common stock in their names, or in the names of their nominees, that are beneficially owned by others, send proxy materials to and obtain proxies from those beneficial owners, and, upon request, will reimburse those holders for their reasonable expenses in performing those services.

Adjournments; Other Procedural Matters

If a quorum is not present in person or represented by proxy at the special meeting, the chairperson of the meeting may adjourn the meeting from time to time to a date not more than 120 days after the record date for the special meeting, without notice other than announcement at the special meeting. At the adjourned special meeting at which a quorum is present, any business may be transacted that might have been transacted at the special meeting as originally notified.

If a quorum is present in person or represented by proxy at the special meeting, but there are not sufficient votes at the special meeting to approve the REIT Merger, then the persons named as proxies on the proxy card may be asked to approve one or more adjournments of the special meeting to permit further solicitation of proxies. The persons named as proxies on the proxy card will only have the authority to approve such adjournments as instructed by you or your proxy. Any adjournment of the special meeting for the purpose of soliciting additional proxies will allow our stockholders who have already granted their proxies to revoke them at any time prior to their use. Please see “Approval for Certain Adjournments of the Special Meeting” on page 60.

The grant of a proxy will confer discretionary authority on the persons named as proxies on the proxy card to vote in their discretion on procedural matters incident to the conduct of the special meeting. If the persons named as proxies on the proxy card are asked to vote for one or more adjournments of the special meeting for matters incidental to the conduct of the special meeting, as opposed to adjournments to solicit additional proxies, such persons will have the authority to vote in their discretion on such matters.

Upon completion of the REIT Merger, all shares of our common stock will be automatically cancelled and converted into the right to receive the cash consideration described below under “The Merger Agreement—Consideration to be Received in the Merger—REIT Merger Consideration.”

Immediately following the REIT Merger, SSGT OP will merge with and into SST II OP, with SST II OP being the surviving entity in the Partnership Merger. We already have taken all actions necessary to approve the Partnership Merger and no further approval of any of the limited partners of SSGT OP is required to complete the Partnership Merger. As such, this proxy statement does not constitute any solicitation of consents with respect to the Partnership Merger.

Background of the REIT Merger

We were incorporated in March 2013 and we commenced our initial public offering in January 2015. In connection with our initial public offering, we indicated that we intended to achieve, within three to five years after completion of our initial public offering, and subject to prevailing market conditions, a liquidity event by merging, reorganizing or otherwise transferring our company or our assets to another entity that has listed securities, by selling our properties and liquidating, by listing our shares on a national securities exchange, or otherwise by creating a liquidity event for our stockholders.

Since completion of our initial public offering, our board of directors periodically and in the ordinary course has reviewed our strategic plan. As part of that review process, our board of directors has considered, among other things, our operational and financial performance, our business outlook, macroeconomic factors, and the

19

real estate valuation environment and real estate valuation trends. In addition, our board of directors has also considered the various challenges we face as a public company andnon-traded REIT, including the competitive environment for acquiring self storage real estate assets and the challenges of owning and managing a portfolio of growth properties, as well as the net losses and accumulated deficits we have incurred. We face intense competition in every market in which we purchase or develop self storage facilities. We compete with numerous national, regional and local developers, owners and operators in the self storage industry, some of which have greater capital resources, greater cash reserves, less demanding rules governing distributions to stockholders and a greater ability to borrow funds to acquire self storage facilities. Likewise, given our smaller scale relative to other public self storage REITs, our cost of capital has remained higher than that of those other REITs and, because our shares are not listed on a national securities exchange, we have less ability to raise new capital.

As part of its regular review of our strategic plan and over the course of several meetings, our board of directors discussed the possibility of engaging in a liquidity event. Our board of directors, with the input and assistance of our management, reviewed investment opportunities and possible strategic alternatives that could be available to us, including, among other things, analyzing joint venture opportunities with large institutional investors or increasing our leverage to acquire additional growth properties and the potential short-term erosion of our estimated net asset value.

On February 23, 2018, we held a board retreat to continue the discussion of our strategic alternatives. During this meeting, representatives of KeyBanc made a presentation to the board relating to a capital markets update, the REIT market, the self storage market and self storage REITs. In addition, representatives of CBRE Group, Inc. made a presentation to the board on the general state of the self storage industry.

In early March 2018, we were contacted by representatives of SST II to see if there would be interest in considering a potential transaction. Our board of directors was familiar with SST II and its portfolio because both we and SST II are sponsored by SmartStop, an entity that provides real estate advisory, asset management and property management services to us and SST II. There is also substantial overlap between our management and the SST II management team, and Mr. Schwartz, who is our Chief Executive Officer and the Chairman of our board of directors, is also the Chief Executive Officer of SST II and the Chairman of the SST II board of directors. Our board of directors thought a potential transaction with SST II could achieve the liquidity objective noted above. Accordingly, our board of directors authorized management to enter into a nondisclosure agreement with SST II to explore, on a preliminary basis, a potential transaction with SST II.

On March 16, 2018, we entered into a nondisclosure agreement with SST II.

On May 16, 2018, in light of the possibility of potential conflicts of interest in our board of directors’ consideration of strategic alternatives, including, but not limited to, a potential transaction with SST II, at a joint meeting of our board of directors and our board of directors’ nominating and corporate governance committee (the “SSGT governance committee”), our board of directors and the SSGT governance committee formed the SSGT special committee consisting of Leon W. Holmes and Stephen G. Muzzy, and delegated to the SSGT special committee the authority to review and evaluate strategic alternatives for SSGT, including a potential sale of the company or its assets. Mr. Holmes and Mr. Muzzy are members of our board of directors who are independent from our management and do not serve as directors of SST II. Mr. Holmes was appointed as the Chairman of the SSGT special committee. At the May 16 joint meeting, the engagement of Bass, Berry & Sims PLC (“Bass Berry”) as counsel to the SSGT special committee was authorized, as was the engagement of Shapiro Sher Guinot & Sandler, P.A. (“Shapiro Sher”) as counsel to the SSGT special committee with respect to matters of Maryland law. The SSGT governance committee also discussed the role and selection of a financial advisor to advise the SSGT special committee. The SSGT governance committee concluded that the SSGT special committee should consider various financial advisors before selecting one to advise the SSGT special committee.

On May 24, 2018, we received a term sheet (the “May 24 term sheet”) from the special committee of the board of directors of SST II, which was formed to consider a potential transaction with us (the “SST II special

20

committee”), proposing an all cash merger transaction that valued our real estate portfolio at $365.0 million, subject to various adjustments (“purchase adjustments”), including balance sheet adjustments for our remaining capital expenditures, our outstanding debt, our cash on hand and other net assets, and the fees and expenses we would be expected to incur in the transaction. The purchase adjustments made by the SST II special committee equated to deductions of approximately $51.8 million. The May 24 term sheet also provided for a “no shop” clause (to prevent solicitation of alternative acquisition proposals from other parties), a termination fee equal to 3.0% of equity value payable by us to SST II upon certain events of termination, expense reimbursement by us to SST II in the event our stockholders do not approve the merger, and a60-day exclusivity period. The May 24 term sheet provided that the closing of the transaction would not be conditioned on SST II obtaining any necessary financing.

On May 25, 2018, the SSGT special committee met, together with representatives of Bass Berry and Shapiro Sher, to review the May 24 term sheet and to discuss the engagement of a financial advisor. The SSGT special committee discussed four investment banking firms to potentially serve as the SSGT special committee’s financial advisor, and the SSGT special committee determined not to negotiate with SST II without first engaging a financial advisor and having that financial advisor perform a preliminary valuation analysis of SSGT. At the direction of the SSGT special committee, that same day Bass Berry informed representatives of Robert A. Stanger & Co. (“Stanger”), as the financial advisor to the SST II special committee, Nelson Mullins Riley & Scarborough LLP (“Nelson Mullins”), as SST II’s regular corporate counsel, and Venable LLP (together with Nelson Mullins, the “SST II legal advisors”), as the SST II special committee’s counsel, that the SSGT special committee was in the process of considering financial advisors and would respond after a financial advisor had been engaged.

During the week of May 28, 2018, the SSGT special committee contacted each of the four investment banking firms that were discussed at its May 25 meeting regarding the financial advisory engagement, and the SSGT special committee requested materials from each firm with respect to its qualifications to serve as financial advisor. Following review of the materials provided, the SSGT special committee determined to formally interview two of the firms.

On June 4, 2018, the SSGT special committee separately met with each of the two firms to review their capabilities and qualifications for acting as the financial advisor to the SSGT special committee, including a review of any past or existing relationships between the firm and its affiliates, on the one hand, and either SSGT or SST II, on the other.

On June 6, 2018, the SSGT special committee met, together with representatives of Bass Berry, to discuss the engagement of a financial advisor. After discussing the qualifications of, and the SSGT special committee’s interviews with, both candidate firms, the SSGT special committee elected to engage KeyBanc to serve as its financial advisor. That determination was based on a number of factors, including, among others, KeyBanc’s experience in the REIT industry, particularly both withnon-traded REITs and the self storage sector. The SSGT special committee also considered the historical lending relationship between us and KeyBank N.A., an affiliate of KeyBanc, as well as SST II’s historical lending relationship with KeyBank N.A. and its potential role in providing financing for any potential transaction. Given those lending relationships involving KeyBanc’s affiliate, the SSGT special committee also confirmed with KeyBanc its ability to deliver a fairness opinion in connection with a potential transaction.

On June 7, 2018, KeyBanc provided a draft of its engagement letter to the SSGT special committee. On June 8, 2018, the SSGT special committee met with representatives of Bass Berry to discuss the terms of the engagement letter. From June 8, 2018 through June 13, 2018, Bass Berry, on behalf of the SSGT special committee, and KeyBanc negotiated the terms of the engagement letter. On June 13, 2018, the SSGT special committee and KeyBanc entered into an engagement letter for KeyBanc to serve as the SSGT special committee’s exclusive financial advisor for the purpose of assisting the SSGT special committee in its consideration and evaluation of any potential transaction, including the transaction set forth in the May 24 term sheet from SST II.

On June 19, 2018, Shapiro Sher distributed an advisory memorandum to our board of directors regarding statutory standards of conduct under the MGCL, in advance of the June 20 meeting.

On June 20, 2018, our board of directors met, together with representatives of Bass Berry, Shapiro Sher and Nelson Mullins, as SSGT’s regular corporate counsel. Shapiro Sher reviewed with our board of directors the standards of conduct required of directors under the MGCL, both generally and in connection with proposed strategic alternatives. Our board of directors also discussed with representatives of Bass Berry, Shapiro Sher and Nelson Mullins the purpose and adoption of indemnification agreements for our directors and executive officers, after which our board of directors approved indemnification agreements for our directors and executive officers. Our board of directors, with input and assistance from Bass Berry, Shapiro Sher and Nelson Mullins, also discussed and determined the compensation for the members of the SSGT special committee, which was aone-time payment and not conditioned upon our entry into or consummation of a transaction. In light of Nelson Mullins’s role as regular corporate counsel to both SSGT and SST II, there was no discussion of any potential transaction at this meeting.

Following the meeting of our board of directors, on June 20, 2018, the SSGT special committee met, together with representatives of Bass Berry and Shapiro Sher, to discuss possible alternatives to a sale of the company to SST II. The SSGT special committee, with input and assistance of Bass Berry and Shapiro Sher, discussed benefits and disadvantages of performing a market check prior to entering into a definitive transaction agreement, whether with SST II or otherwise, compared to marketing the company during a go shop period once a definitive transaction agreement is entered into. At that time, the SSGT special committee determined that it should have KeyBanc’s preliminary valuation analysis prior to deciding whether to conduct apre-signing market check.

On June 27, 2018, we entered into indemnification agreements with each of our directors and executive officers. In addition, on June 27, 2018, our board of directors considered and approved an amendment to our bylaws adding a forum selection provision.

On June 28, 2018, the SSGT special committee met with representatives of Bass Berry and KeyBanc. KeyBanc updated the SSGT special committee on the status of KeyBanc’s valuation analysis and KeyBanc provided the SSGT special committee with KeyBanc’s preliminary valuation of our real estate portfolio, subject to the remaining work to be performed by KeyBanc as part of its valuation analysis.

On July 3, 2018, we publicly announced, through the filing of a Current Report on Form8-K with the SEC, that our board of directors had established the SSGT special committee to conduct a review of strategic alternatives and address any potential conflicts of interest, that the SSGT special committee had initiated a strategic review process to identify, examine, and consider a range of strategic alternatives available to us with the objective of maximizing stockholder value, and that the SSGT special committee had engaged KeyBanc as its financial advisor and Bass Berry as its legal counsel in connection with that strategic review process.

On July 18, 2018, the SSGT special committee met with representatives of Bass Berry and KeyBanc. At the meeting, KeyBanc presented its initial valuation analysis to the SSGT special committee. Based on that analysis, the SSGT special committee determined that it should engage in negotiations with SST II given the attractiveness of the value proposed by SST II in its May 24 term sheet. The SSGT special committee also discussed with Bass Berry and KeyBanc a proposed response by the SSGT special committee to SST II’s May 24 term sheet.

On July 20, 2018, the SSGT special committee met again, together with representatives of Bass Berry, to discuss the SSGT special committee’s response to the May 24 term sheet. At the direction of the SSGT special committee, Bass Berry sent a revised term sheet to Stanger and the SST II legal advisors, on behalf of SST II, that same day (the “July 20 term sheet”). The July 20 term sheet valued our real estate portfolio at $391.3 million, subject to purchase adjustments of approximately $38.3 million that the SSGT special committee considered appropriate. In addition, the July 20 term sheet provided for a45-day go shop period, a termination fee of 0.50% of

22

equity value during the go shop period and a termination fee of 2.50% of equity value after the go shop period, additional termination rights for SSGT (including upon SST II’s failure to obtain the necessary financing for the transaction), a reverse termination fee equal to 7.5% of equity value payable by SST II to us upon SST II’s failure to obtain the necessary financing for the transaction, no expense reimbursement by us to SST II in the event our stockholders do not approve the merger, and a60-day exclusivity period.

On July 22, 2018, representatives of Bass Berry and Stanger held a call to discuss certain aspects of the July 20 term sheet, including the real estate portfolio valuation and the purchase adjustments.

On July 25, 2018, the SSGT special committee received a revised term sheet from SST II (the “July 25 term sheet”) which valued our real estate portfolio at $372.4 million, subject to the SST II special committee’s purchase adjustments of approximately $52.7 million. The July 25 term sheet also provided for a30-day go shop period, a termination fee of 1.50% of equity value during the go shop period and a termination fee of 3.00% of equity value after the go shop period, no reverse termination fee payable by SST II to us, reimbursement of transaction-related expenses upon the occurrence of certain termination events (including termination if our stockholders do not approve the merger), and a60-day exclusivity period.

On July 26, 2018, representatives of KeyBanc and Stanger held a call to discuss the valuation and purchase adjustments reflected in the July 25 term sheet.

On July 30, 2018, the SSGT special committee met, together with representatives from Bass Berry, Shapiro Sher and KeyBanc, to review and discuss the July 25 term sheet. KeyBanc presented its analysis of the July 25 term sheet, including various financial metrics implied by SST II’s valuation of our real estate portfolio. The SSGT special committee and KeyBanc also discussed the purchase adjustments reflected by the July 25 term sheet. The SSGT special committee also discussed, with input and assistance from Bass Berry, Shapiro Sher and KeyBanc, the terms of a proposed response to the July 25 term sheet.

On July 31, 2018, representatives of KeyBanc and Stanger held another call to discuss differences in the calculation of their respective purchase adjustments.

On August 2, 2018, the SSGT special committee met with representatives of Bass Berry, Shapiro Sher and KeyBanc to continue the discussion regarding the July 25 term sheet. KeyBanc reviewed with the SSGT special committee our financial information as of June 30, 2018 and the impact of that updated information on the purchase adjustments. Bass Berry and Shapiro Sher also reviewed with the SSGT special committee other proposed changes to the July 25 term sheet. With the recommendations of KeyBanc, Bass Berry and Shapiro Sher, the SSGT special committee approved a revised term sheet and directed Bass Berry to submit it to SST II.

On August 2, 2018, following the meeting of the SSGT special committee, Bass Berry provided the revised term sheet (the “August 2 term sheet”) to Stanger and the SST II legal advisors, on behalf of SST II. The August 2 term sheet valued our real estate portfolio at $376.1 million, subject to purchase adjustments of approximately $52.3 million that the SSGT special committee considered appropriate. The August 2 term sheet also provided for a45-day go shop period, a termination fee of 0.50% of equity value during the go shop period and a termination fee of 3.00% of equity value after the go shop period, a reverse termination fee equal to 3.00% of equity value payable by SST II to us upon SST II’s failure to obtain the necessary financing for the transaction, a cap of $750,000 on each party’s obligation to reimburse the other for transaction-related expenses upon the occurrence of certain termination events, no expense reimbursement by us to SST II in the event our stockholders do not approve the merger, and a45-day exclusivity period.

On August 3, 2018, the SSGT special committee received a revised term sheet from SST II (the “August 3 term sheet”). The August 3 term sheet valued our real estate portfolio at $374.4 million, subject to the SST II special committee’s purchase adjustments of approximately $53.7 million, which equated to a price per share of our common stock of $12.00. The August 3 term sheet also provided for a45-day go shop period, a termination

23

fee of 1.50% of equity value during the go shop period and a termination fee of 3.00% of equity value after the go shop period, a reverse termination fee equal to 3.00% of equity value payable by SST II to us upon SST II’s failure to obtain the necessary financing for the transaction, a cap of $2,000,000 on each party’s obligation to reimburse the other for transaction-related expenses upon the occurrence of certain termination events (including termination if our stockholders do not approve the merger), and a60-day exclusivity period. SST II characterized the August 3 term sheet as its best and final proposal.

On August 3, 2018, representatives of KeyBanc and Stanger held a call to discuss the amount of the go shop termination fee set forth in the August 3 term sheet, as well as the purchase adjustments reflected in the August 3 term sheet. Likewise, on August 3, 2018, representatives of Bass Berry and the SST II legal advisors held a call to discuss the amount of the go shop termination fee set forth in the August 3 term sheet.

On August 6, 2018, in a call between representatives of Bass Berry and the SST II legal advisors, the SST II legal advisors confirmed that the share price set forth in the August 3 term sheet represented SST II’s best and final proposal on price, but that the other terms in the August 3 term sheet may be negotiable.

On August 6, 2018, the SSGT special committee met, together with representatives of Bass Berry, Shapiro Sher and KeyBanc, to discuss the August 3 term sheet. KeyBanc presented its analysis of the August 3 term sheet. Bass Berry reviewed with the SSGT special committee the differences between the August 2 term sheet and the August 3 term sheet. The SSGT special committee also discussed, with input and assistance from KeyBanc and Bass Berry, the potential process for marketing SSGT during a go shop period, including potential bidders that could be contacted on behalf of SSGT by KeyBanc.

On August 7, 2018, representatives of Bass Berry and the SST II legal advisors held a call to discuss the go shop termination fee and the expense reimbursement provisions in the August 3 term sheet.

On August 7, 2018, the SSGT special committee received a revised term sheet from SST II (the “August 7 term sheet”). The August 7 term sheet provided for all cash merger consideration of $12.00 per share of our common stock, the same price set forth in the August 3 term sheet. The August 7 term sheet also provided for a45-day go shop period, a termination fee of 0.90% of equity value during the go shop period and a termination fee of 3.00% of equity value after the go shop period, a reverse termination fee equal to 3.00% of equity value payable by SST II to us upon SST II’s failure to obtain the necessary financing for the transaction, a cap of $2,000,000 on each party’s obligation to reimburse the other for transaction-related expenses upon the occurrence of certain termination events, no expense reimbursement by us to SST II in the event our stockholders do not approve the merger, and a60-day exclusivity period. SST II characterized the August 7 term sheet as its best and final proposal in all respects.

On August 7, 2018, the SSGT special committee met with representatives from Bass Barry, Shapiro Sher and KeyBanc to discuss the August 7 term sheet. KeyBanc and Bass Berry reviewed with the SSGT special committee the terms of the August 7 term sheet and the status of negotiations with SST II. The SSGT special committee, with input and assistance from Bass Berry and KeyBanc, discussed the possibility of further negotiating the financial and/or legal terms, as well as the risks associated with continued negotiations in light of the belief that the $12.00 share price was a compelling value proposition. After careful consideration of the August 7 term sheet, the SSGT special committee accepted the August 7 term sheet and directed Bass Berry to communicate the SSGT special committee’s acceptance to the SST II legal advisors, which Bass Berry did that same day.

On August 10, 2018, the SSGT special committee received a proposed exclusivity andnon-disclosure agreement from SST II that provided for an exclusivity period of up to 60 days, consistent with the August 7 term sheet. Certain other terms of the exclusivity andnon-disclosure agreement were negotiated between Bass Berry, on behalf of the SSGT special committee, and the SST II legal advisors on August 10, 2018, and the parties executed the exclusivity andnon-disclosure agreement on August 11, 2018.

On August 10, 2018, our board of directors approved the suspension of our distribution reinvestment plan (the “DRP”), effective as of August 23, 2018, and our share redemption program (the “SRP”), effective as of September 12, 2018. On August 13, 2018, we issued a letter to our stockholders regarding the suspension of the DRP and the SRP.

On August 17, 2018, at the direction of the SSGT special committee, Bass Berry distributed an initial draft of the Merger Agreement to the SST II legal advisors. That initial draft of the Merger Agreement was expressly subject to further comment by the SSGT special committee and KeyBanc, to the extent not inconsistent with the August 7 term sheet. From August 17, 2018 through September 30, 2018, the Merger Agreement was revised in accordance with the outcomes of negotiations between the parties, with a particular focus on the scope of the representations and warranties and interim operating covenants, as well as termination rights and remedies. With the initial and each revised draft of the Merger Agreement, the SSGT special committee met with Bass Berry to discuss the terms of the agreement and proposed revisions.

On October 1, 2018, the SSGT special committee held a meeting, with representatives of Bass Berry, Shapiro Sher and KeyBanc present. KeyBanc reviewed its valuation analysis with the SSGT special committee and KeyBanc provided its fairness opinion, orally confirming that, as of the date of the meeting, the proposed consideration to be paid to our stockholders was fair, from a financial point of view, to the unaffiliated holders. The SSGT special committee discussed with KeyBanc its fairness opinion, as well as KeyBanc’s expectations regarding the go shop process following the execution of the Merger Agreement. Shapiro Sher reviewed with the SSGT special committee the specific statutory duties owed by the members of the SSGT special committee under the MGCL in connection with the proposed transaction, and Bass Berry reviewed with the SSGT special committee the material terms of the Merger Agreement. The SSGT special committee unanimously approved the Merger Agreement and declared its recommendation to our board of directors that it do the same.

On October 1, 2018, following the conclusion of the SSGT special committee meeting, our board of directors also held a meeting, with representatives of Bass Berry, Shapiro Sher and KeyBanc present. KeyBanc reviewed its valuation analysis with our board of directors and KeyBanc provided its fairness opinion, orally confirming that, as of the date of the meeting, the proposed consideration to be paid to our stockholders was fair, from a financial point of view, to the unaffiliated holders. Shapiro Sher reviewed with our board of directors the specific statutory duties owed by our directors under the MGCL in connection with the proposed transaction, and Bass Berry reviewed with our board of directors the material terms of the Merger Agreement. Mr. Schwartz announced that, given the related party nature of the proposed transaction, he would abstain from the vote regarding the approval of the Merger Agreement. With Mr. Schwartz abstaining, and upon the recommendation of the SSGT special committee, the independent members of our board of directors unanimously approved the Merger Agreement, directed that the REIT Merger (upon the terms and subject to the conditions of the Merger Agreement) be considered at a special meeting of our common stockholders, and recommended to our common stockholders that the REIT Merger be approved (upon the terms and subject to the conditions of the Merger Agreement).

On October 1, 2018, following the meeting of our board of directors, SSGT and SST II executed and delivered the Merger Agreement, and we issued a press release and filed with the SEC a Current Report onForm 8-K announcing the execution of the Merger Agreement.

Following the execution of the Merger Agreement, pursuant to the go shop covenant set forth in the Merger Agreement, KeyBanc, acting on behalf of the SSGT special committee, commenced the go shop process by soliciting alternative acquisition proposals. The go shop period expired at 11:59 p.m. (Eastern time) on November 15, 2018. During the go shop period, KeyBanc contacted 32 prospective buyers that the SSGT special committee and KeyBanc believed could have interest in reviewing the opportunity and had the financial ability to pursue a potential transaction. Of the 32 prospective buyers contacted, 19 parties entered into confidentiality agreements with us and were provided access to a data room containing certainnon-public information relating to us. None of the parties contacted during the go shop process, including the 19 parties that entered into

25

confidentiality agreements with us, submitted an acquisition proposal to us or our representatives prior to the expiration of the go shop period.

Reasons for the REIT Merger and Recommendation of Our Board of Directors

In evaluating the REIT Merger, the Merger Agreement and the other transactions contemplated by the Merger Agreement, our board of directors consulted with the SSGT special committee’s legal and financial advisors and considered the unanimous recommendation of the SSGT special committee. In reaching their respective determinations that the Merger Agreement and the transactions contemplated by the Merger Agreement, including the REIT Merger, are fair and reasonable, both financially and otherwise, to SSGT and advisable and in the best interests of SSGT and our stockholders, our board of directors and the SSGT special committee considered a number of factors, including the following material factors which our board of directors and the SSGT special committee viewed as supporting their respective decisions to approve the Merger Agreement, the REIT Merger and the other transactions contemplated by the Merger Agreement and for our board of directors to recommend approval of the REIT Merger pursuant to the Merger Agreement to our stockholders:

• the REIT Merger consideration of $12.00 per share represents a premium to our most recently announced net asset value of $11.58 per share;

• the REIT Merger consideration is payable in cash and will provide our stockholders with immediate and certain value and liquidity for their shares, especially when viewed against the risks and uncertainties of our business (see “Risk Factors” in our Annual Report on Form10-K for the year ended December 31, 2017 filed with the SEC on March 21, 2018);

• the fact that the REIT Merger consideration is a fixed cash amount and will not be adjusted for any change in the value of shares of our common stock, which limits the impact of external factors on the REIT Merger;

• the fact that the REIT Merger consideration to be paid to our stockholders is $12.00 per share, compared to the initial public offering price for our common stock of $10.00 per share (which initial public offering price was later increased following our determination of an estimated value per share of our common stock);

• the indication we gave, when conducting our initial public offering beginning in January 2015, that we intended to seek a liquidity event for our stockholders within approximately three to five years following our initial public offering;

• the belief that the REIT Merger is more favorable to our stockholders than other strategic alternatives available to us, including acquisition by a different buyer, listing on a national securities exchange, selling our properties or remaining an independent,non-traded REIT;

• the financial presentation of KeyBanc and its oral opinion, subsequently confirmed by delivery of its written opinion dated October 1, 2018 (attached to this proxy statement as Annex B) that, as of that date, and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations on the scope of review undertaken by KeyBanc as set forth in its written opinion, the REIT Merger consideration of $12.00 per share to be paid to our common stockholders pursuant to the Merger Agreement was fair, from a financial point of view, to the unaffiliated holders (see “—Opinion of Our Financial Advisor”);

• the terms and conditions of the Merger Agreement, which were reviewed by the SSGT special committee and our board of directors with the SSGT special committee’s financial and legal advisors, and the fact that such terms were the product of arms’ length negotiations between the parties;

• the fact that the Merger Agreement provides us a45-day go shop period during which we may actively solicit any inquiries or the making of any proposal that constitutes, or may reasonably be expected to lead to, any “Acquisition Proposal” (as defined in “The Merger Agreement—Covenants and

26

Agreements—No Solicitation of Transactions by SSGT”), providing an opportunity to determine if the offer will result in a “Superior Proposal” (as defined in “The Merger Agreement—Covenants and Agreements—No Solicitation of Transactions by SSGT”);

• the fact that after expiration of the go shop period, the Merger Agreement provides our board of directors with the ability, under certain specified circumstances, and subject to our obligations under the Merger Agreement, to make an “Adverse Recommendation Change” (as defined in “The Merger Agreement—Covenants and Agreements—No Solicitation of Transactions by SSGT”) and to terminate the Merger Agreement in order to enter into an agreement with respect to a Superior Proposal;

• the fact that the termination fee payable by us under the Merger Agreement, whether during or after the “go shop” period, was viewed, after consultation with the SSGT special committee’s legal and financial advisors, as reasonable and not likely to preclude another party from making a competing acquisition proposal;

• the limited and otherwise customary conditions to the parties’ obligations to complete the Mergers, and the fact that the terms and conditions of the Merger Agreement minimize, to the extent reasonably practical, the risk that a condition to closing would not be satisfied;

• the high probability that the REIT Merger would be completed based on, among other things, the lack of a financing condition, no requirement for SST II stockholder approval and the $9.6 million reverse termination fee payable to us if the Merger Agreement is terminated under certain circumstances;

• our ability to seek specific performance to require SST II and Merger Sub to complete the REIT Merger pursuant to the Merger Agreement;

• our ability to declare and pay dividends through the closing of the REIT Merger, consistent with past practice;

• favorable conditions for sale transactions in the real estate markets generally and the self storage sector specifically, with capitalization rates near historical lows;

• our board of directors’ and the SSGT special committee’s knowledge of our business, operations, financial condition, earnings and prospects, as well as their knowledge of the current and prospective environment in which we operate, including economic and market conditions;

• the risks and uncertainty of remaining an independent public company, given our smaller scale relative to other public self storage REITs, which has caused our cost of capital to remain higher than that of our larger peers and the fact that we are not listed on a national securities exchange, which could impede our ability to raise new capital; and

• the fact that the REIT Merger would be subject to the approval of our stockholders, and our stockholders would be free to reject the REIT Merger by voting against the REIT Merger for any reason, including if a higher offer were to be made prior to the special meeting (although we may be required to pay SST II a termination fee or provide SST II expense reimbursement under certain circumstances).

Our board of directors and the SSGT special committee also considered a variety of risks and other potentially negative factors in its consideration of the Merger Agreement, the REIT Merger and the other transactions contemplated by the Merger Agreement, including the following material factors:

• the risk that a different strategic alternative could prove to be more beneficial to our stockholders than the REIT Merger;

• the fact that the REIT Merger would preclude our stockholders from having the opportunity to participate in the future performance of our assets, future potential earnings growth, future potential appreciation of the value of our common stock or future dividends that could be realized depending on our future performance;

27

• the significant costs involved in connection with entering into and completing the REIT Merger and the substantial time and effort required to consummate the REIT Merger and related disruptions to the operation of our business;

• the restrictions on the conduct of our business prior to the completion of the REIT Merger, which could delay or prevent us from undertaking business opportunities that may arise pending completion of the REIT Merger;

• the pendency of the REIT Merger or failure to complete the REIT Merger may cause harm to relationships with our business associates and may divert management attention away from theday-to-day operation of our business;

• the risk that, under the terms of the Merger Agreement, SSGT may be obligated to pay SST II a termination fee in the amount of $2.9 million or $9.6 million, depending upon the circumstances, or up to $2 million in expense reimbursement, in certain circumstances;

• the fact that the terms of the Merger Agreement place limitations on our ability to initiate, solicit, knowingly encourage or facilitate any inquiries or the making of any proposal, offer or other action that constitutes any Acquisition Proposal after November 15, 2018, which is the end of the go shop period;

• the possibility that the REIT Merger may not be completed, or that completion of the REIT Merger may be delayed for reasons that are beyond our or SST II’s control;

• SST II may not be able to raise the cash required to consummate the REIT Merger and the other transactions contemplated by the Merger Agreement on a timely basis or at all;

• the fact that an all cash merger would be taxable to our stockholders for U.S. federal income tax purposes;

• the fact that, under the MGCL and our charter, our stockholders will not be entitled to appraisal rights, dissenters’ rights or similar rights of an objecting stockholder in connection with the REIT Merger;

• the fact that, since both SSGT and SST II are REITs sponsored by SmartStop, there are conflicts of interest inherent when individuals who serve on the management teams of SSGT and SST II are assisting both our board of directors and the SST II board of directors in connection with the Mergers, and one of our directors and some of our executive officers have interests with respect to the Mergers that are different from, or in addition to, those of our stockholders generally (see “Interests of Certain Persons in the Mergers”); and

• the types and nature of the risks and uncertainties described under the caption “Cautionary Statement Regarding Forward-Looking Statements” in this proxy statement.

The foregoing discussion of the factors considered by our board of directors and the SSGT special committee is not intended to be exhaustive and is not provided in any specific order or ranking, but rather includes the material factors considered by our board of directors and the SSGT special committee. In reaching their respective decisions to approve the REIT Merger pursuant to the Merger Agreement, our board of directors and the SSGT special committee did not quantify, rank or otherwise assign any relative weights to, and did not make specific assessments of, the factors considered, and individual directors may have given different weights to different factors.

The explanation of the factors and reasoning set forth above contain forward-looking statements and should be read in conjunction with the section of this proxy statement entitled “Cautionary Statement Regarding Forward-Looking Statements.” After considering the foregoing potentially negative and potentially positive factors, our board of directors and the SSGT special committee concluded that the potentially positive factors relating to the Merger Agreement, the REIT Merger and the other transactions contemplated by the Merger Agreement substantially outweighed the potentially negative factors.

After careful consideration, for the reasons set forth above and based on the unanimous recommendation of the SSGT special committee, our board of directors has (1) determined that the Merger Agreement and the

28

transactions contemplated thereby, including the REIT Merger, are fair and reasonable, both financially and otherwise, to SSGT and advisable and in the best interests of SSGT and our stockholders and (2) approved the Merger Agreement and the transactions contemplated thereby, including the REIT Merger.

For these reasons, our board of directors (with Mr. Schwartz abstaining) unanimously recommends a vote “FOR” the proposal to approve the REIT Merger pursuant to the Merger Agreement.

Opinion of Our Financial Advisor

The SSGT special committee retained KeyBanc to act as its financial advisor in connection with the REIT Merger. In selecting KeyBanc, the SSGT special committee considered, among other things, the fact that KeyBanc is a reputable investment banking firm with substantial experience advising companies in the self storage sector and in providing strategic advisory services in general.

On October 1, 2018, KeyBanc rendered an oral opinion to the SSGT special committee and, at the SSGT special committee’s direction, to our board of directors, which was subsequently confirmed in a written opinion as of the same date, as to the fairness, from a financial point of view, to the unaffiliated holders, and based upon and subject to the assumptions made, matters considered and limitations and qualifications upon the review undertaken by KeyBanc, of the consideration to be paid to the unaffiliated holders pursuant to the Merger Agreement.

The full text of KeyBanc’s written opinion, dated October 1, 2018, is attached to this proxy statement as Annex B. You should read KeyBanc’s opinion carefully and in its entirety for a discussion of, among other things, the scope of the review undertaken and the assumptions made, procedures followed, matters considered and qualifications and limitations upon the review undertaken by KeyBanc in connection with its opinion. This summary is qualified in its entirety by reference to the full text of the opinion. KeyBanc’s opinion was prepared for the use of the SSGT special committee and our board of directors, and addressed only the fairness from a financial point of view, as of the date of the opinion, of the consideration to be paid to the unaffiliated holders pursuant to the Merger Agreement. It does not constitute a recommendation as to how any stockholder should vote with respect to the REIT Merger or any other matter, and does not in any manner address the price at which shares of our common stock will trade at any time, if ever.

In connection with rendering its opinion, KeyBanc, among other things:

• reviewed an execution copy of the Merger Agreement;

• reviewed certain publicly available information concerning SSGT;

• reviewed certain other internal information, primarily financial in nature, concerning our business and operations furnished to KeyBanc by us for purposes of its analysis;

• reviewed certain publicly available information with respect to certain other companies that KeyBanc believed to be comparable to SSGT; and

• reviewed certain publicly available information and other information known to KeyBanc concerning the nature and terms of certain other transactions that KeyBanc considered relevant to its inquiry.

In its review and analysis and in arriving at its opinion, KeyBanc assumed and relied upon the accuracy and completeness of all of the financial and other information provided to or otherwise reviewed by or discussed with KeyBanc or publicly available and further relied upon the assurances of our management that they were not aware of any facts or circumstances that would make such information inaccurate or misleading in any material respect. KeyBanc also assumed that the representations and warranties of each of the parties to the Merger Agreement are and will be true and correct in all respects material to its analysis. KeyBanc was not engaged to, and has not independently attempted to, verify any of such information or its accuracy or completeness. KeyBanc

29

also relied upon our management as to the reasonableness and achievability of the projections (and the assumptions and bases therefor) provided to KeyBanc and, with our consent, KeyBanc assumed that such forecast was reasonably prepared on bases that reflected the best available estimates and judgments of our management of our future financial performance and other matters covered thereby. KeyBanc was not engaged to assess the reasonableness or achievability of such projections or the assumptions on which they were based, and KeyBanc expresses no view as to such forecast or assumptions. In addition, KeyBanc has not conducted a physical inspection, valuation or appraisal of any of our assets (including properties or facilities) or liabilities. KeyBanc is also not expressing any view or opinion with respect to, and, at our direction, KeyBanc relied upon, the assessments of our representatives regarding legal, regulatory, accounting, tax and similar matters relating to SSGT and the Mergers, as to which matters KeyBanc understands that we obtained such advice as we deemed necessary from qualified advisors and professionals. KeyBanc also assumed that all governmental, regulatory or other consents, releases and approvals necessary for the consummation of the Mergers will be obtained without any adverse effect on SSGT or the Mergers that would be meaningful to its analysis.

KeyBanc’s opinion is based on economic and market conditions and other circumstances existing on, and information made available to KeyBanc as of, the date of its opinion and does not address any matters subsequent to such date. In addition, KeyBanc’s opinion is, in any event, limited to the fairness, as of the date of its opinion, from a financial point of view, of the consideration to be paid to the unaffiliated holders pursuant to the Merger Agreement and does not address our underlying business decision to engage in the Mergers or any other terms of the Mergers, including the merger consideration paid in the Partnership Merger, or the fairness of the Mergers, or any consideration paid in connection therewith, to our creditors or other SSGT constituencies. In addition, KeyBanc does not express any opinion as to (i) the fairness of the Mergers or (ii) the amount or the nature of the compensation now paid or to be paid, in each case, to any of our directors, officers or employees, or class of such persons, relative to the consideration to be paid to public stockholders of SSGT. KeyBanc has not evaluated nor does it express any opinion on the solvency or viability of the parties to the Merger Agreement or their respective affiliates or the ability of such parties to pay their respective obligations when they come due. It should be noted that although subsequent developments may affect KeyBanc’s opinion, KeyBanc does not have any obligation to update, revise or reaffirm its opinion.

KeyBanc’s opinion does not constitute a recommendation as to any action the SSGT special committee or our board of directors should take in connection with the Mergers or the other transactions contemplated by the Merger Agreement or any aspect thereof and is not a recommendation to any director of SSGT, any security holder or other party on how that person should act or vote with respect to the Mergers or related transactions and proposals or any other matter.

The summary set forth below does not purport to be a complete description of the financial analyses performed by KeyBanc, but describes, in summary form, the material elements of the presentation that KeyBanc made to the SSGT special committee and our board of directors on October 1, 2018, in connection with KeyBanc’s opinion. The following is a summary of the material financial analyses performed by KeyBanc in arriving at its opinion. These summaries of financial analyses alone do not constitute a complete description of the financial analyses KeyBanc employed in reaching its conclusion.

KeyBanc’s opinion was only one of many factors considered by the SSGT special committee and our board of directors in evaluating the proposed Mergers. Neither KeyBanc’s opinion nor its financial analyses were determinative of the REIT Merger consideration or of the views of the SSGT special committee, our board of directors or our management with respect to the REIT Merger consideration or the Mergers. The summary text describing each financial analysis does not constitute a complete description of KeyBanc’s financial analyses, including the methodologies and assumptions underlying the analyses, and if viewed in isolation could create a misleading or incomplete view of the financial analyses performed by KeyBanc. The summary text set forth below does not represent and should not be viewed by anyone as constituting conclusions reached by KeyBanc with respect to any of the analyses performed by it in connection with its opinion. Rather, KeyBanc made its determination as to the fairness, from a financial point of view, to the unaffiliated holders of the REIT Merger

30

consideration to be paid to those stockholders in the REIT Merger pursuant to the Merger Agreement on the basis of its experience and professional judgment after considering the results of all of the analyses performed.

Except as otherwise noted, the information utilized by KeyBanc in its analyses, to the extent that it is based on market data, is based on market data as it existed on or before October 1, 2018 and is not necessarily indicative of current market conditions. The analyses described below do not purport to be indicative of actual future results, or to reflect the prices at which any securities may trade in the public markets, which may vary depending upon various factors, including changes in interest rates, dividend rates, market conditions, economic conditions, and other factors that influence the price of securities.

In conducting its analyses, KeyBanc differentiated among three different types of assets owned by SSGT: (1) established assets that had an operating history as a self storage facility in the market and an established market presence (“Established Assets”); (2) growth assets that were either in development or inlease-up following a renovation,re-development or completion of development (“Growth Assets”); and (3) pipeline assets that were under contract for acquisition (“Pipeline Assets”). In order to reach a view regarding a valuation range for the Established Assets, KeyBanc analyzed the historical and projected financial results of the Established Assets, as well as third-party market statistics, and applied the following valuation techniques: (a) a discounted cash flow analysis; (b) a comparable publicly traded companies analysis; (c) a comparable portfolio transaction analysis; and (d) a net asset value analysis. In addition, KeyBanc utilized the following valuation techniques for the Growth Assets: (i) a discounted cash flow analysis and (ii) a net asset value analysis. Pipeline Assets were valued at purchase price, inclusive of acquisition fees and costs. No individual methodology can be viewed individually. Additionally, no company or transaction used in any analysis as a comparison is identical to SSGT or the Mergers, and they all differ in material ways. Accordingly, an analysis of the results described below involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading value of the selected companies or precedent transactions to which they are being compared. As a consequence, mathematical derivations (such as the high, low, mean and median) of financial data are not by themselves meaningful and in selecting the ranges of multiples to be applied were considered in conjunction with experience and the exercise of judgment. KeyBanc used these analyses to determine the impact of various operating metrics on the implied value per share of our common stock. Each of these analyses yielded a range of implied values, and the implied value ranges developed from these analyses were viewed by KeyBanc collectively and not individually.

Summary of Financial Analyses of our Financial Advisor

Analysis of Discounted Cash Flow

KeyBanc performed an illustrative discounted cash flow analysis of our portfolio, which is designed to determine an implied valuation of our portfolio by discounting to the present the future expected cash flows from the portfolio. KeyBanc performed the discounted cash flow analysis on the Established Assets as a portfolio and on the Growth Assets using assumptions reflective of each Growth Asset’s stage in the growth process.

KeyBanc analyzed the projections of unlevered free cash flows of our portfolio for the fiscal periods beginning July 2018 through June 2023 that were included in the Projections (as defined below). Unlevered free cash flows were determined by taking projected net operating income (“NOI”) of our portfolio for the fiscal periods beginning July 2018 through June 2023 that were included in the Projections and subtracting capital expenditures. In estimating the portfolio’s weighted average cost of capital (“WACC”), KeyBanc performed analysis consistent with the Capital Asset Pricing Model (“CAPM”) using its professional judgment and experience and various assumptions, including the current risk free rate of return, adjustments for market risk and size of SSGT based on third-party data, unlevered beta based on the mean of comparable public companies and are-levered beta using a range of leverage ratios consistent with the comparable publicly traded companies. The WACC calculation resulted in a range of 8.00% to 8.50% WACC for SSGT.

The WACC was used as a discount rate for the Established Assets and those Growth Assets currently inlease-up. For the Fruitland Road and Torbarrie Road Growth Assets, which arein-process developments,

31

KeyBanc applied an estimated discount rate which provides a spread over the portfolio WACC to reflect the additional risk given each development’s remaining completion needs.

For the Established Assets, KeyBanc used a discount rate of 8.25% applied to the Projections to determine the present value of the free cash flow of the Established Assets. KeyBanc then calculated the Established Assets’ terminal value in fiscal year 2023 by applying an exit capitalization rate from the median of the precedent self storage portfolio transactions of 5.30% to the projected 2023 NOI. KeyBanc then calculated the enterprise value of the Established Assets by adding the implied present value of unlevered free cash flows and the implied present value of the terminal value. This analysis implied an enterprise valuation range of $184 million to $202 million for the Established Assets.

For the Growth Assets currently inlease-up, KeyBanc used the same discount rate of 8.25%, based on its WACC calculation, that was used with the Established Assets. For the Fruitland Road and Torbarrie Road Growth Assets, KeyBanc developed individual discount rates and exit capitalization rates to take into account the fact that these assets are in earlier stages in their lifecycle, and the strength of their respective markets. This analysis, collectively, implied an enterprise valuation range of $140 million to $154 million for the combined Growth Assets.

While discounted cash flow analysis is a widely accepted and practiced valuation methodology, it relies on a number of assumptions, including growth rates, terminal multiples and discount rates. The valuation derived from the discounted cash flow analysis is not necessarily indicative of our present or future value or results. Discounted cash flow analysis in isolation from other analyses is not an effective method of evaluating transactions.

Analysis of Comparable Publicly Traded Companies

For the Established Assets, KeyBanc reviewed and compared certain publicly available financial information, valuation multiples, and market trading data relating to SSGT and selected publicly traded companies, including publicly traded equity REITs which principally own and operate self storage properties, that KeyBanc believed, based on its experience with companies in the self storage industry, to be similar to our current operations for purposes of this analysis. Financial data of the selected companies were based on public filings and other publicly available information. For each of these comparable companies, KeyBanc calculated the applicable company’s implied capitalization rate (“Company Cap Rate”) for the next 12 months based on third party data and its professional judgment and experience and calculated the mean Company Cap Rate for the comparable publicly traded companies.

KeyBanc reviewed data of SSGT and each of the following selected publicly traded companies in the self storage industry, the operations of which KeyBanc deemed comparable to the self storage assets included in our portfolio for purposes of this analysis, based on its professional judgment and experience, which companies we refer to as “Peers”.

• Public Storage

• Extra Space Storage

• CubeSmart

• Life Storage

• National Storage Affiliates Trust

The implied forward 12 month Company Cap Rates were 5.6%, 5.1%, 5.9%, 5.8%, and 5.0% for Public Storage, Extra Space Storage, CubeSmart, Life Storage and National Storage Affiliates Trust, respectively, with an average of 5.5%. KeyBanc applied the average of the Company Cap Rates implied by public market values of

32

each of the comparable companies to the Established Assets’ projected 2018 NOI of $9.8 million and applied a range based on a spread of 0.25% to the average Company Cap Rate. As a result, KeyBanc determined an implied enterprise value range of the Company’s Established Assets of $171 million to $187 million.

No company utilized in the selected publicly traded companies analysis is identical to SSGT. In particular, each of the selected publicly traded companies is larger than SSGT and has liquid stock. In evaluating selected publicly traded companies, KeyBanc made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters which are beyond our control, such as the impact of competition on us and the industry generally, industry growth, and the absence of any material adverse change in our financial condition and prospects or the self storage industry or the financial markets in general.

Analysis of Comparable Portfolio Transactions

KeyBanc also performed an analysis of selected comparable portfolio transactions involving self storage companies that shared certain characteristics with the Mergers. Such analysis was only utilized to analyze the value of the Established Assets as the portfolio transaction comparables largely consist of established portfolios. Based on publicly available information and industry research reports, including certain financial data and the purchase prices paid, KeyBanc identified 12 completed transactions involving self storage companies occurring since 2013. For each of these transactions for comparison purposes, KeyBanc applied the ranges implied by the 25th and 75th percentiles of the transaction comparables to the projected 2018 NOI for the Established Assets, which equaled a range of 5.2% to 5.5% (the “Cap Rate Range”). KeyBanc also applied a 5% range in either direction around the averagedollar-per-square foot metric for the transaction comparables to the square footage of the Established Assets, which equaled a range of $161 to $178 (the “Square Foot Range”). In establishing a range of potential values for the Established Assets as compared to the transaction comparables, KeyBanc utilized both the Cap Rate Range and the Square Foot Range. To create a low end and high end, KeyBanc utilized the lowest implied value and the highest implied value between the Cap Rate Range and the Square Foot Range, respectively. The selected transactions and corresponding data were as follows:

Closed Date	Acquirer	Seller	Purchase Price ($ million)		$ / SF		Cap Rate
July 10, 2018	National Storage Affiliates, Heitman	Simply Self Storage	$	1,325.0	$	152		5.6	%

This analysis indicated the following implied portfolio valuation:

	Transaction Statistics

The comparable transactions analysis was used only to analyze the value of the Established Assets, as the comparable companies’ portfolios primarily consist of established assets. No company or portfolio transaction utilized as a comparison in the analysis of selected comparable portfolio transactions is identical to SSGT or directly comparable to the Mergers in business mix, timing and size. Accordingly, an analysis of the results of the foregoing necessarily involves complex considerations and judgments concerning differences in financial and operating characteristics and other factors that would affect the value of the companies to which we are being compared. In evaluating the selected precedent transactions, KeyBanc made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters which are beyond our control, such as the impact of competition on SSGT and the industry generally, industry growth and the absence of any adverse material change in our financial conditions and prospects or the self storage industry or the financial markets in general.

Net Asset Value Analysis

KeyBanc reviewed certain financial data and the purchase prices paid in 337 real estate transactions involving self storage assets, for which relevant information was publicly available or available from third-party data sources commonly used in the real estate industry, to determine a net asset value for our portfolio. KeyBanc selected the 337 asset sale transactions based on the following criteria:

• closed transactions involving individual self storage assets in the same geographic market as the relevant portfolio asset (geographic range varies based on transaction volume within each market);

• transactions completed since May 2016; and

• transactions including assets of similar quality wheredollar-per-square foot data was disclosed.

KeyBanc obtained the capitalization rate, which is generally the net operating income of a subject property divided by the purchase price (the “Property Cap Rate”) and thedollar-per-square foot metric, which is generally the purchase price divided by the square footage of the subject property (the “Square Foot Metric”), for each of the selected transactions from third-party data sources commonly used in the real estate industry. For Established Assets, KeyBanc applied the Property Cap Rate to individual properties that are generally in cities with a population of greater than 100,000 individuals or within 20 miles of a major city and to individual properties which KeyBanc evaluated and deemed the Property Cap Rate relevant to such property. Alternatively, KeyBanc applied the Square Foot Metric generally to individual properties in markets that have more consistentdollar-per-square foot data but limited publicly available comparable capitalization rate information and to individual properties which KeyBanc evaluated and deemed the Property Cap Rate less relevant. KeyBanc applied a 15% portfolio premium to the total net asset value to reflect the appropriate premium a portfolio the size of SSGT’s could be expected to achieve. KeyBanc utilized those results to determine an estimated gross asset value of the Established Assets of $182 million, and applied a range of 5% above and below this estimate. As a result, KeyBanc determined an implied enterprise value range of our Established Assets of $173 million to $191 million.

34

For Growth Assets other than Fruitland Road and Torbarrie Road, KeyBanc only utilized the Square Foot Metric for each selected transaction because KeyBanc determined that, given the growth nature of the Growth Assets, applying a capitalization rate approach was not appropriate. Each Square Foot Metric calculated was applied to the individual assets. KeyBanc determined high and low ranges by applying a 5% range to the average Square Foot Metric value of the comparable single asset transactions, and KeyBanc also applied a 15% premium to the total net asset value to reflect a customary premium a portfolio the size of SSGT’s could be expected to achieve. For the Fruitland Road and Torbarrie Road Growth Assets, KeyBanc utilized the values determined for these assets in the discounted cash flow analysis, as there was not sufficient comparable data to calculate a relevant Square Foot Metric for these Canadian assets. As a result of these analyses, KeyBanc calculated an implied enterprise value range of our Growth Assets of $128 million to $141 million.

No asset utilized in the net asset value analysis is identical to any of the assets in our portfolio. For example, the transactions used in this analysis occurred in different economic climates than the current one, involved companies with different property profiles and were completed using different consideration. KeyBanc made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of the parties to the Merger Agreement. Net asset value analysis in isolation from other analyses is not an effective method of evaluating transactions.

Miscellaneous

In connection with KeyBanc’s services as the financial advisor to the SSGT special committee, pursuant to a letter agreement dated June 13, 2018, we will pay KeyBanc an aggregate fee of approximately $1,500,000, $500,000 of which was payable upon KeyBanc’s delivery of its opinion, and the remaining portion of which is payable upon, and subject to, consummation of the Mergers. In addition, we have agreed to reimburse KeyBanc for certain of its expenses and to indemnify KeyBanc and related persons against various potential liabilities, including certain liabilities that may arise in connection with KeyBanc’s engagement.

KeyBanc affiliates performed banking and related services for us during the past two years and received aggregate compensation from us of approximately $400,000. In addition, KeyBanc and its affiliates, including KeyBank N.A., which is the sole book runner, sole lead arranger and administrative agent under SST II’s existing amended and restated revolving credit facility, provided commercial and investment banking services to SST II during the past two calendar years, for which SST II paid aggregate compensation of approximately $5.33 million. Given the existing relationship between KeyBank N.A. and SST II, SST II currently anticipates that KeyBank N.A. will have involvement in the financing to be entered into by SST II in connection with the consummation of the Mergers. KeyBanc apprised the SSGT special committee of KeyBank N.A.’s lending relationship with SST II prior to its engagement by the SSGT special committee, and the SSGT special committee considered that relationship in making its determination to engage KeyBanc as its financial advisor. See “The REIT Merger—Background of the REIT Merger” on page 19.

KeyBanc, as part of its investment banking business, is engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, and private placements. In the ordinary course of business, certain of KeyBanc’s employees and affiliates, as well as investment funds in which they may have financial interests or with which they mayco-invest, may acquire, hold or sell, long or short positions, or trade, in debt, equity, and other securities and financial instruments (including loans and other obligations) of, or investments in, SSGT, SST II, or any other party that may be involved in the Mergers and their respective affiliates or any currency or commodity that may be involved in the Mergers. KeyBanc or its affiliates may provide investment and corporate banking services to SSGT, SST II and their respective affiliates in the future, for which KeyBanc or its affiliates may receive customary fees. KeyBanc provides a full range of financial advisory and securities services and, in the course of its normal trading activities, may from time to time effect transactions and hold securities, including, without limitation, derivative securities, of SSGT, SST II, or their respective affiliates for its own account and for the accounts of customers.

Certain Unaudited Prospective Financial Information of SSGT

We do not as a matter of course make public financial projections or estimates as to future revenues, earnings or other results given, among other reasons, the uncertainty, unpredictability and subjectivity of the underlying assumptions and estimates. However, in connection with KeyBanc’s consideration of the Mergers, certain forward-looking financial information prepared by our management was provided to KeyBanc, which were based on our management’s consolidated financial model (which we refer to as the “Projections”). The Projections assume (1) a property management fee of approximately 6% of revenues included in operating expenses, (2) a stabilization of Growth Assets occurring by 2021, (3) a property level rental rate growth of 3% or 4% upon stabilization, and (4) capital expenditures of 5% of NOI. We have included the Projections in this proxy statement to give our stockholders access to certain nonpublic information considered by the SSGT special committee, our board of directors and KeyBanc for purposes of considering and evaluating the Mergers, but not to influence the decision of stockholders whether to vote for or against the approval of the REIT Merger. The inclusion of this information should not be regarded as an indication that the SSGT special committee, our board of directors, KeyBanc, or any other recipient of this information considered, or now considers, this information to be material or a reliable prediction of future results.

The Projections are subjective in many respects. Although presented with numerical specificity, the Projections reflect and are based on numerous assumptions and estimates with respect to industry performance, general business, economic, political, market and financial conditions, competitive uncertainties, and other matters, all of which are difficult to predict and beyond our control. As a result, there can be no assurance that these Projections will be realized or that actual results will not be significantly higher or lower than projected. The Projections are forward-looking statements and should be read with caution. Holders of shares of our common stock are urged to review the risks and uncertainties described under the caption “Cautionary Statement Regarding Forward-Looking Statements” on page 14 as well as the risks described in the periodic reports we have filed with the SEC. The Projections reflect assumptions as to certain business matters that are subject to change.

The Projections were prepared to assist the SSGT special committee and our board of directors in evaluating the Mergers and not with a view toward public disclosure or toward complying with GAAP, the published guidelines of the SEC regarding projections or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of projections. Our independent registered public accounting firm has not examined or compiled any of the Projections, expressed any conclusion or provided any form of assurance with respect to the Projections and, accordingly, assumes no responsibility for them. The Projections should be evaluated, if at all, in conjunction with the historical financial statements and other information regarding SSGT contained in our public filings. Readers of this proxy statement are cautioned not to place undue reliance on the specific portions of the Projections set forth below. No one has made or makes any representation to any stockholder regarding the information included in these Projections. The Projections do not take into account any circumstances or events occurring after the date they were prepared, including the transactions contemplated by the Merger Agreement. Further, the Projections do not take into account the effect of any failure of the Mergers to occur and should not be viewed as accurate or continuing in that context.Except as may be required by applicable securities laws, we do not intend to update, or otherwise revise, the Projections or the specific portions presented to reflect circumstances existing after the date when made or to reflect the occurrence of future events, even in the event that any or all of the assumptions are shown to be in error.

For the foregoing reasons, as well as the bases and assumptions on which the Projections were compiled, the inclusion of specific portions of the Projections in this proxy statement should not be regarded as an indication that the Projections are an accurate prediction of future events, and they should not be relied on as such.

The following is a summary of the Projections:

	Projections Year Ended December 31 (Dollars in millions)
	2018P		2019P		2020P		2021P		2022P

Financing and SST II Stockholder Approval

Consummation of the Mergers is not conditioned upon SST II obtaining financing and does not require approval by SST II stockholders. The transaction value of the Mergers is approximately $350 million, which includes outstanding debt to be assumed or repaid by SST II as of November 15, 2018, but excludes transaction costs. SST II has represented in the Merger Agreement that it will have sufficient funds to consummate the Mergers. SST II has advised us that it is in the process of negotiating new loans in order to finance the Mergers, which would include the financing of our properties, the refinancing of certain of SST II’s existing properties, and the payoff of certain of SST II’s existing loans.

Deregistration of Our Common Stock

If the REIT Merger is completed, our common stock will be deregistered under the Exchange Act.

Regulatory Matters

We are unaware of any material federal, state or foreign regulatory requirements or approvals that are required for the execution of the Merger Agreement or the completion of the Mergers, other than the filing of the articles of merger with, and the acceptance of such articles of merger for record by, the State Department of Assessments and Taxation of Maryland, in respect of the REIT Merger, and the filing of a certificate of merger or other appropriate documents with the Secretary of State of the State of Delaware, in respect of the Partnership Merger.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

The following is a summary of the material U.S. federal income tax consequences of the REIT Merger to holders of our common stock whose shares are cancelled in the REIT Merger and automatically converted into the right to receive the merger consideration as described herein. This summary is based on current law, is for general information only and is not tax advice. This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), applicable Treasury Regulations, and administrative and judicial interpretations thereof, each as in effect as of the date hereof, all of which are subject to change or to different interpretations, possibly with retroactive effect. We have not requested, and do not plan to request, any rulings from the Internal Revenue Service (the “IRS”) concerning our tax treatment or the tax treatment of the REIT Merger, and the statements in this proxy statement are not binding on the IRS or any court. We can provide no assurance that the tax consequences contained in this discussion will not be challenged by the IRS, or if challenged, will be sustained by a court.

This summary assumes that shares of our common stock are held as capital assets within the meaning of Section 1221 of the Code and does not address all aspects of taxation that may be relevant to particular holders in light of their personal investment or tax circumstances or to persons that are subject to special tax rules and does not address the tax consequences of the REIT Merger to holders of restricted stock or the tax consequences of the Partnership Merger to the holders of the OP Units. In addition, this summary does not address the tax treatment of special classes of holders of our common stock, including, for example:

• banks and other financial institutions;

37

• insurance companies;

• regulated investment companies;

• REITs;

• tax-exempt entities or persons holding our common stock in atax-deferred or tax advantaged account;

• mutual funds;

• subchapter S corporations;

• dealers in securities or currencies;

• traders in securities that elect to use amark-to-market method of accounting for their securities holdings;

• persons whose functional currency is not the U.S. dollar;

• persons holding shares of our common stock as part of a hedge or conversion transaction or as part of a “straddle” or a constructive sale;

• U.S. expatriates;

• persons subject to the alternative minimum tax;

• holders of our restricted stock or who otherwise acquired shares of our common stock as compensation;

• holders that are properly classified as a partnership or otherwise as a pass-through entity under the Code;

• non-U.S. holders, as defined below (except to the extent specifically set forth below); and

• “controlled foreign corporations,” “passive foreign investment companies,” or corporations that accumulate earnings to avoid U.S. federal income tax.

If any entity that is treated as a partnership for U.S. federal income tax purposes holds our common stock, the tax treatment of its partners or members generally will depend upon the status of the partner or member and the activities of the entity. If you are a partner of a partnership or a member of a limited liability company or other entity classified as a partnership for U.S. federal income tax purposes and that entity holds our common stock, you should consult your tax advisor. Moreover, each holder should consult its tax advisor regarding the U.S. federal income tax consequences to it of the REIT Merger in light of its own particular situation, as well as any consequences of the REIT Merger to such holder arising under the laws of any other taxing jurisdiction.

For purposes of this section, a “U.S. holder” means a beneficial owner of our common stock that is, for U.S. federal income tax purposes:

• an individual citizen or resident of the United States;

• a corporation, or other entity treated as a corporation for U.S. federal income tax purposes created or organized in or under the laws of the United States or any state or political subdivision thereof;

• a trust (1) the administration of which is subject to the primary supervision of a U.S. court and with respect to which one or more “United States persons” (as defined under the Code) have the authority to control all substantial decisions, or (2) that was in existence on August 20, 1996, was treated as a United States person on the previous day, and elected to continue to be so treated; or

• an estate the income of which is subject to U.S. federal income taxation regardless of its source.

As used in this section, a“non-U.S. holder” means a beneficial owner of shares of our common stock that is not a U.S. holder.

38

Consequences to Us of the REIT Merger

For U.S. federal income tax purposes, we will treat the REIT Merger as if we had (i) sold all of our assets to Merger Sub in exchange for the merger consideration and the assumption of our liabilities outstanding as of the closing date and then (ii) made a liquidating distribution of the merger consideration to our stockholders in exchange for their shares of our common stock. Because as a REIT we are entitled to receive a deduction for liquidating distributions and we anticipate that our deemed liquidating distribution will exceed our taxable income recognized as a result of the REIT Merger, we anticipate that we will not be subject to U.S. federal income tax on any gain recognized in connection with the REIT Merger and the other transactions contemplated by the Merger Agreement.

Consequences of the REIT Merger to U.S. Holders

General. The receipt of cash by U.S. holders in exchange for their stock pursuant to the REIT Merger will be a taxable transaction for U.S. federal income tax purposes (and also may be a taxable transaction under applicable state, local and foreign income and other tax laws). In general, a U.S. holder of our common stock will recognize gain or loss for U.S. federal income tax purposes equal to the difference between:

• the amount of cash received in exchange for our common stock; and

• the U.S. holder’s adjusted tax basis in our common stock.

Gain or loss will be calculated separately for each block of shares of stock, with a block consisting of shares acquired at the same cost in a single transaction. This gain or loss will generally be capital gain or loss and will be long-term capital gain or loss if at the time of the REIT Merger the stock has been held for more than one year. An individual U.S. holder will be subject to tax on net capital gain at a maximum U.S. federal income tax rate of 20%. Additionally, the 3.8% tax on net investment income will apply to any gain recognized by individuals, trusts and estates whose income exceeds certain threshold levels.

Capital gains of corporate U.S. holders generally are taxable at the regular tax rates applicable to corporations. The deductibility of a capital loss recognized in the exchange is subject to limitations under the Code. In addition, the IRS has the authority to prescribe, but has not yet prescribed, regulations that would apply a tax rate of 25% to a portion of capital gain realized by anon-corporate stockholder on the sale of REIT stock that would correspond to the REIT’s “unrecaptured Section 1250 gain.”

Special Rule for U.S. Holders Who Have Held our Common Stock Less than Six Months. A U.S. holder who has held our common stock for less than six months at the time of the REIT Merger, taking into account the holding period rules of Section 246(c)(3) and (4) of the Code, and who recognizes a loss on the exchange of our common stock in the REIT Merger, will be treated as recognizing a long-term capital loss to the extent of any capital gain dividends received from us, or such holder’s share of any designated retained capital gains, with respect to such stock.

Consequences of the REIT Merger toNon-U.S. Holders

General. The U.S. federal income tax consequences of the REIT Merger to anon-U.S. holder will depend on various factors, including whether the receipt of the merger consideration is treated as a distribution from us to our stockholders that is attributable to gain from the sale of “United States real property interests.” The IRS announced in Notice2007-55 that it intends to (1) take the position that under current law anon-U.S. holder’s receipt of a liquidating distribution from a REIT (including, in our case, the receipt of cash in exchange for our common stock in the REIT Merger, which will be treated as a deemed liquidation for U.S. federal income tax purposes) is generally subject to tax under FIRPTA as a distribution to the extent attributable to gain from the sale of United States real property interests, and (2) issue regulations that will be effective for transactions occurring on or after June 13, 2007, clarifying this treatment. Although legislation effectively overriding Notice

39

2007-55 has previously been proposed, no such legislation has yet been enacted, and it is not possible to say if or when any such legislation will be enacted. As a result, the following paragraphs provide alternative discussions of the tax consequences that would arise to the extent the tax treatment set forth in Notice2007-55 does or does not apply. Notwithstanding the discussion in the following paragraphs, we intend to take the position that the cash received in exchange for our common stock will be subject to tax in accordance with Notice2007-55 as described in more detail below. In general, the provisions governing the taxation of distributions by REITs can be less favorable tonon-U.S. holders than the taxation of sales or exchanges of REIT stock bynon-U.S. holders, andnon-U.S. holders should consult their tax advisors regarding the application of these provisions.

Distribution of Gain from the Disposition of U.S. Real Property Interests. To the extent the tax treatment set forth in Notice2007-55 applies, and to the extent cash received bynon-U.S. holders in the REIT Merger is attributable to gain from the deemed sale of our United States real property interests (which we expect to be a substantial portion of such cash), then such amount will be treated as income effectively connected with a United States trade or business of thenon-U.S. holder and generally will be subject to U.S. federal income tax on a net basis. A corporatenon-U.S. holder will also be subject to the 30% branch profits tax (or such lower rate as may be specified by an applicable income tax treaty). In addition, 21% (or 20% to the extent provided in Treasury Regulations) of any such amounts paid to anon-U.S. holder will be withheld and remitted to the IRS.

Notwithstanding the foregoing, to the extent the tax treatment set forth in Notice2007-55 does not apply, or if anon-U.S. holder has not owned more than 5% of our common stock at any time during theone-year period ending on the date of the REIT Merger and our common stock is “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market located in the United States, the 21% withholding tax described above would not apply, and suchnon-U.S. holder would instead be subject to the rules described below under “—Taxable Sale of our Common Stock.” Our common stock is not regularly traded on an established securities market in the United States as of the date of this proxy statement.

Taxable Sale of our Common Stock. Subject to the discussion of withholding and of distribution of gain from the disposition of United States real property interests above, if the REIT Merger is treated as a taxable sale of our common stock, anon-U.S. holder should not be subject to U.S. federal income taxation on any gain or loss from the REIT Merger unless: (1) the gain is effectively connected with thenon-U.S. holder’s conduct of a trade or business in the United States, or, if an applicable income tax treaty applies, the gain is attributable to a permanent establishment maintained by thenon-U.S. holder in the United States; (2) thenon-U.S. holder is an individual present in the United States for 183 days or more in the taxable year of the REIT Merger and certain other requirements are met; or (3) such shares of stock constitute a “United States real property interest” under FIRPTA.

Anon-U.S. holder whose gain is effectively connected with the conduct of a trade or business in the United States will generally be subject to U.S. federal income tax on such gain on a net basis in the same manner as a U.S. holder. In addition, anon-U.S. holder that is a corporation may be subject to the 30% branch profits tax on such effectively connected gain described in clause (1) of the previous paragraph.

Anon-U.S. holder who is an individual present in the United States for 183 days or more in the taxable year of the REIT Merger and who meets certain other requirements will be subject to a flat 30% tax on the gain derived from the REIT Merger, which may be offset by United States source capital losses. In addition, thenon-U.S. holder may be subject to applicable alternative minimum taxes.

If anon-U.S. holder’s stock constitutes a United States real property interest under FIRPTA, any gain recognized by such holder in the REIT Merger will treated as income effectively connected with a United States trade or business of thenon-U.S. holder and generally will be subject to U.S. federal income tax on a net basis in the same manner as a U.S. holder. In addition, 15% of any amounts realized by anon-U.S. holder will be withheld and remitted to the IRS. Anon-U.S. holder’s shares of our common stock generally will not constitute a U.S. real property interest if either (1) we are a “domestically controlled qualified investment entity” at the

40

effective time, or (2) both (a) that class of our stock is regularly traded on an established securities market at the date of the REIT Merger and (b) thenon-U.S. holder holds 5% or less of the total fair market value of that class of stock at all times during the shorter of (x) the five-year period ending with the effective date of the REIT Merger and (y) thenon-U.S. holder’s holding period for the stock. As discussed above, our common stock is not regularly traded on an established securities market as of the date of this proxy statement. A “qualified investment entity” includes a REIT. Assuming we qualify as a REIT, we will be a “domestically controlled qualified investment entity” at the effective time ifnon-U.S. holders held directly or indirectly less than 50% in value of our common stock at all times during the five-year period ending with the effective time. While we believe that we currently are a domestically controlled REIT, no assurances can be given that the actual ownership of our stock has been or will be sufficient for us to qualify as a “domestically controlled qualified investment entity” at the effective time.

Income Tax Treaties. If anon-U.S. holder is eligible for treaty benefits under an income tax treaty with the United States, thenon-U.S. holder may be able to reduce or eliminate certain of the U.S. federal income tax consequences discussed above, such as the branch profits tax.Non-U.S. holders should consult their tax advisor regarding possible relief under an applicable income tax treaty.

U.S. Withholding Tax. As described above, it is unclear whether the receipt of the merger consideration by anon-U.S. holder will be treated as a sale or exchange of our common stock or as a distribution from us that is attributable to gain from the deemed sale of our United States real property interests in the REIT Merger. Accordingly, we intend to withhold U.S. federal income tax at a rate of 21% (or 20% to the extent provided in applicable Treasury Regulations) from the portion of the merger consideration that is, or is treated as, attributable to gain from the sale of United States real property interests and paid to anon-U.S. holder.

Anon-U.S. holder may be entitled to a refund or credit against the holder’s U.S. federal income tax liability, if any, with respect to any amount withheld pursuant to FIRPTA, provided that the required information is furnished to the IRS on a timely basis.Non-U.S. holders should consult their tax advisor regarding withholding tax considerations.

Information Reporting and Backup Withholding

Backup withholding, currently at a rate of 24%, and information reporting may apply to the cash received pursuant to the exchange of our common stock in the REIT Merger. Backup withholding will not apply, however, to a holder who:

• in the case of a U.S. holder, furnishes a correct taxpayer identification number and certifies that it is not subject to backup withholding on an IRS FormW-9 or successor form;

• in the case of anon-U.S. holder, furnishes an applicable IRS FormW-8 or successor form; or

• is otherwise exempt from backup withholding and complies with other applicable rules and certification requirements.

Backup withholding is not an additional tax and any amount withheld under these rules may be credited against the holder’s U.S. federal income tax liability and may entitle the holder to a refund if required information is timely furnished to the IRS.

Additional Withholding Tax on Payments Made to Foreign Accounts

Withholding taxes may be imposed under Sections 1471 through 1474 of the Code (such Sections commonly referred to as FATCA) on certain types of payments made tonon-U.S. financial institutions and certain othernon-U.S. entities. The application of FATCA to the payment of the merger consideration made to anon-U.S. holder with respect to our common stock pursuant to the REIT Merger is not entirely clear. We urge you to consult your tax advisor regarding FATCA and the application of these rules to such payment.

41

THE FOREGOING DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OF THE POTENTIAL TAX CONSIDERATIONS RELATING TO THE REIT MERGER AND IS NOT TAX ADVICE. THEREFORE, HOLDERS OF OUR COMMON STOCK ARE STRONGLY URGED TO CONSULT THEIR TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE REIT MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF U.S. FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX LAWS IN THEIR PARTICULAR CIRCUMSTANCES.

INTERESTS OF CERTAIN PERSONS IN THE MERGERS

In considering the recommendation of our board of directors with respect to the REIT Merger, stockholders should be aware that our directors and executive officers have interests in the Mergers that may be different from, or in addition to, those of our stockholders generally. These interests may create potential conflicts of interest. Our board of directors and the SSGT special committee were aware of these interests and considered them, among other matters, in reaching their respective decisions to approve the REIT Merger pursuant to the Merger Agreement.

Sponsorship by SmartStop

We and SST II are bothnon-traded REITs sponsored by SmartStop. H. Michael Schwartz, the Chairman and Chief Executive Officer of SmartStop, is the Chairman of both our board of directors and the SST II board of directors and he is also our Chief Executive Officer as well as the Chief Executive Officer of SST II. In addition, our other executive officers are also executive officers of SmartStop, and most of our other executive officers are also executive officers of SST II. Likewise, a majority of our executive officers are also officers of our external Advisor, SS Growth Advisor, LLC, and the external advisor to SST II. Both our Advisor and SST II’s external advisor are controlled by SmartStop, and SmartStop is controlled by Mr. Schwartz.

Given that the individuals who substantially comprise the management teams of both SSGT and SST II are the same individuals and those individuals are assisting both our board of directors and the SST II board of directors in connection with the Mergers, certain conflicts of interest exist.

Restricted Stock Held by our Directors

Under the terms of the Merger Agreement, immediately prior to the effective time of the REIT Merger, the vesting and forfeiture restrictions on shares of our restricted stock granted under our Employee and Director Long-Term Incentive Plan will lapse and such shares will be fully vested in the holder thereof. Shares of restricted stock will have the same rights and be subject to the same conditions in the REIT Merger as shares of our common stock not subject to any vesting or forfeiture restrictions, including the right to receive the merger consideration. Upon completion of the REIT Merger, holders of restricted shares will be entitled to receive $12.00, without interest and less applicable withholding taxes, for each share of restricted stock that is vested immediately prior to the effective time of the REIT Merger. In connection with the REIT Merger, an aggregate of 9,688 shares of restricted stock owned by our independent directors will vest and will convert into the right to receive cash in the aggregate amount of approximately $116,000 (prior to reduction for any applicable tax withholding).

Additionally, immediately prior to the effective time of the REIT Merger, we will pay in cash to all holders of restricted stock an amount equal to all accrued but unpaid dividends owed to each such holder. The aggregate accrued but unpaid dividends payable to our independent directors with respect to their shares of restricted stock is approximately $5,000 as of October 31, 2018.

42

Disposition Fee to our Advisor

Pursuant to our Advisory Agreement with our Advisor, upon completion of the Mergers, our Advisor will be entitled to receive a cash disposition fee in an amount of approximately $3.7  million, which is 1% of the implied value of our real estate portfolio in the Mergers.

Redemption of Special Limited Partner Interest

Pursuant to the special limited partner interest held by our Advisor in SSGT OP, our Advisor is entitled to receive, in redemption of that special limited partner interest, a subordinated distribution upon the closing of the Mergers, equal to 15% of the amount by which the transaction amount (which equals the value of our outstanding common stock) plus the amount payable to our Advisor pursuant to this transaction, plus all distributions paid to common stockholders, exceeds the sum of our stockholders’ invested capital, plus the amount required to pay our stockholders a 6% cumulative,non-compounded, annual return on invested capital. Such subordinated distribution is anticipated to equal approximately $4.0 million, and is payable in cash or OP Units, at the election of our Advisor. We anticipate that our Advisor will elect to receive OP Units. However, as our Advisor’s special limited partner interest will not be redeemed until the completion of the Partnership Merger and the OP Units will be converted automatically into units of partnership interest in SST II OP in the Partnership Merger, the SSGT Advisor would instead receive units of partnership interest in SST II OP for the redemption of its special limited partner interest in SSGT OP. As a result, our Advisor would receive 372,288 units of limited partnership interest in SST II OP for the redemption of its special limited partner interest in SSGT OP.

OP Units

The Merger Agreement provides that, in the Partnership Merger, each OP Unit will be converted into the right to receive 1.127 units of partnership interests in SST II OP, without interest and less applicable withholding taxes. As a result of our Advisor’s anticipated election to receive OP Units in connection with the redemption of the special limited partner interest, we anticipate that, immediately prior to the closing of the Mergers, Mr. Schwartz, our Chairman and Chief Executive Officer, will beneficially own OP Units, which will be converted into the right to receive units of partnership interest in SST II OP upon completion of the Partnership Merger, in the following amounts:

Executive Officer	OP Units			Units of Partnership Interest in SST II to be Received as Partnership Merger Consideration
H. Michael Schwartz		350,435	(1)		394,940	(2)

⁽¹⁾ Includes 20,100 OP Units owned by our Advisor, which is indirectly owned and controlled by Mr. Schwartz. Also includes 330,335 OP Units that we anticipate our Advisor would be entitled to receive upon redemption of its special limited partner interest in SSGT OP. See “—Redemption of Special Limited Partner Interest” above.

⁽²⁾ Pursuant to the Merger Agreement, in the Partnership Merger, each OP Unit will be converted into the right to receive 1.127 units of partnership interest in SST II OP.

Indemnification and Insurance

The Merger Agreement provides that rights relating to indemnification, exculpation, advancement of expenses and directors’ and officers’ insurance for our current directors and officers will be continued for six years after the completion of the REIT Merger. These arrangements are described more fully in “The Merger Agreement—Covenants and Agreements—Indemnification of Directors and Officers; Insurance,” beginning on page 54.

43

Paying Agent

We anticipate that SST II will engage Strategic Transfer Agent Services, LLC (“STAS”) to serve as the paying agent to handle the payment and delivery of the REIT Merger consideration. SmartStop, which is controlled by Mr. Schwartz, owns 100% of the membership interests of STAS. For services as the paying agent, we anticipate that STAS will be paid a fee of $50,000.

THE MERGER AGREEMENT

This section of this proxy statement summarizes the material provisions of the Merger Agreement, which is attached as Annex A to this proxy statement and which we incorporate into this proxy statement. As a stockholder, you are not a third party beneficiary of the Merger Agreement and therefore you may not directly enforce any of its terms and conditions.

This summary may not contain all of the information about the Merger Agreement that is important to you. We urge you to carefully read the full text of the Merger Agreement as the rights and obligations of the parties are governed by the express terms of the Merger Agreement and not by this summary or any other information contained in this proxy statement. The Merger Agreement is not intended to provide you with any factual information about SSGT or SST II. In particular, the assertions embodied in the representations and warranties contained in the Merger Agreement (and summarized below) are qualified by information each of SSGT and SST II filed with the SEC prior to the effective date of the Merger Agreement, as well as by disclosure letters each party delivered to the other in connection with the signing of the Merger Agreement, that modify, qualify and create exceptions to the representations and warranties set forth in the Merger Agreement. Moreover, some of those representations and warranties may not be accurate or complete as of any specified date, may apply contractual standards of materiality in a way that is different from what may be viewed as material by investors or that is different from standards of materiality generally applicable under the U.S. federal securities laws or may not be intended as statements of fact, but rather as a way of allocating risk among the parties to the Merger Agreement. The representations and warranties and other provisions of the Merger Agreement and the description of such provisions in this proxy statement should not be read alone but instead should be read in conjunction with the other information contained in the reports, statements and filings that each of SSGT and SST II file with the SEC and the other information in this proxy statement. See “Where You Can Find More Information” beginning on page 62.

We acknowledge that, notwithstanding the inclusion of the foregoing cautionary statements, we are responsible for considering whether additional specific disclosures of material information regarding material contractual provisions are required to make the statements in this proxy statement not misleading.

Structure, Effective Time and Closing of the Mergers

The Merger Agreement provides for the merger of SSGT with and into Merger Sub, upon the terms and subject to the conditions set forth in the Merger Agreement. Merger Sub will be the surviving entity in the REIT Merger and, following completion of the REIT Merger, will continue as a direct wholly-owned subsidiary of SST II. The Merger Agreement also provides for the merger of SSGT OP with and into SST II OP upon the terms and subject to the conditions set forth in the Merger Agreement. SST II OP will be the surviving entity in the Partnership Merger. The Partnership Merger will occur immediately after the REIT Merger. The REIT Merger will become effective upon the time of filing of articles of merger with, and acceptance for record of articles of merger by, the State Department of Assessments and Taxation of the State of Maryland or at a later date and time agreed to by SSGT and SST II and specified in the articles of merger. The Partnership Merger will become effective upon the filing of a certificate of merger with the Secretary of State of the State of Delaware or at a later date and time agreed to by SSGT OP and SST II OP and specified in the partnership certificate of merger.

The Merger Agreement provides that the closing of the Mergers will take place on the third business day following the date on which the last of the conditions to closing of the Mergers (described under “The Merger

44

Agreement—Conditions to Completion of the Mergers”) have been satisfied or waived (other than the conditions that by their terms are to be satisfied at the closing of the Mergers, but subject to the satisfaction or waiver of those conditions) or at such other date and time agreed to by SSGT and SST II.

Consideration to be Received in the Merger

REIT Merger Consideration.If the REIT Merger is completed, each share of SSGT common stock outstanding immediately prior to the REIT Merger, including both Class A common stock and Class T common stock, will be automatically cancelled and converted into the right to receive an amount in cash equal to $12.00, without interest and less any applicable withholding taxes. In the event SSGT splits, combines, or otherwise reclassifies the SSGT common stock, makes a dividend or other distribution in shares of the SSGT common stock (but not including shares of SSGT common stock issued pursuant to the SSGT distribution reinvestment plan), or engages in a reclassification, reorganization, recapitalization, or other like change, then the amount of the REIT Merger consideration will be appropriately and proportionately adjusted to provide to the holders of shares of SSGT common stock the same economic effect as contemplated by the Merger Agreement prior to the change.

Partnership Merger Consideration. If the Partnership Merger is completed, (1) each SSGT OP Unit outstanding immediately prior to the Partnership Merger will be automatically cancelled and converted into the right to receive 1.127 SST II OP Units, and (2) the SSGT Special Limited Partner Interest (as defined in the Merger Agreement) will be redeemed for an amount determined in accordance with the SSGT OP partnership agreement, which amount is payable in cash or SST II OP Units at the election of our Advisor, as the holder of the SSGT Special Limited Partner Interest. In the event our Advisor elects to receive SST II OP Units in lieu of a cash payment, the SSGT Special Limited Partner Interest will be redeemed in exchange for a number of SST II OP Units equal to (a) the quotient of (i) the amount of cash determined in accordance with the SSGT OP partnership agreement that otherwise would have been paid for the redemption of the SSGT Special Limited Partner Interest, divided by (ii) $12.00, multiplied by (b) 1.127.

Conversion of Shares; Letter of Transmittal. The conversion of shares of SSGT common stock into the right to receive the REIT Merger consideration will occur automatically at the effective time of the REIT Merger. In accordance with the Merger Agreement, SST II will appoint a paying agent to handle the payment and delivery of the REIT Merger consideration. Promptly after the completion of the REIT Merger, but not later than three business days thereafter, the paying agent will send a letter of transmittal to those persons who were SSGT stockholders of record at the effective time of the REIT Merger. This mailing will contain instructions regarding the surrender of shares of SSGT common stock in exchange for the consideration that the holder of such shares is entitled to receive under the Merger Agreement. Upon proper surrender of a share for exchange and cancellation to the paying agent, together with a properly completed and signed letter of transmittal, and delivery of any other documents specified in the letter of transmittal, the holder of such share will receive the REIT Merger consideration in accordance with the Merger Agreement.

Treatment of SSGT Restricted Stock. Immediately prior to the effective time of the REIT Merger, each then outstanding share of SSGT restricted stock issued under SSGT’s Employee and Director Long-Term Incentive Plan will fully vest. All shares of SSGT common stock then outstanding as a result of the full vesting of shares of SSGT restricted stock, and the satisfaction of any applicable withholding taxes, will have the right to receive the REIT Merger consideration.

Withholding.All payments under the Merger Agreement are subject to applicable withholding requirements.

Representations and Warranties

The Merger Agreement contains a number of representations and warranties made by SSGT and SSGT OP, on the one hand, and SST II, SST II OP and Merger Sub, on the other hand. The representations and warranties

45

were made by the parties as of the date of the Merger Agreement and do not survive the effective time of the REIT Merger.

Definition of “Material Adverse Effect”

Many of the representations of SSGT, SSGT OP, SST II, SST II OP and Merger Sub are qualified by a “material adverse effect” standard (that is, they will not be deemed to be untrue or incorrect unless their failure to be true or correct, individually or in the aggregate, has not had and would not reasonably be expected to have a material adverse effect).

For purposes of the Merger Agreement, a “material adverse effect” with respect to either SSGT or SST II is any event, circumstance, change, effect, development, condition or occurrence that individually or in the aggregate (1) would have a material adverse effect on the business, assets, liabilities, condition (financial or otherwise) or results of operations of SSGT or SST II (and their respective subsidiaries), taken as a whole, or (2) would prevent or materially impair the ability of SSGT or SST II to close the Mergers before April 1, 2019. However, with respect to the preceding clause (1), a “material adverse effect” would not include any event, circumstance, change, effect, development, condition or occurrence to the extent arising out of or resulting from: (a) any failure of SSGT or SST II to meet any projections or forecasts or any estimates of earnings, revenues or other metrics for any period (provided, that any event, circumstance, change, effect, development, condition or occurrence giving rise to such failure may be taken into account in determining whether there has been a material adverse effect); (b) any changes that affect the self-storage industry generally; (c) any changes in the United States or global economy or capital, financial or securities markets generally, including changes in interest or exchange rates; (d) any changes in the legal, regulatory or political conditions in the United States or in any other country or region of the world; (e) the commencement, escalation or worsening of a war or armed hostilities or the occurrence of acts of terrorism or sabotage occurring after the date of the Merger Agreement; (f) the execution and delivery of the Merger Agreement, or the public announcement of the Mergers or the other transactions contemplated by the Merger Agreement; (g) the taking of any action expressly required by the Merger Agreement, or the taking of any action at the written request or with the prior written consent of SSGT or SST II, as the case may be; (h) earthquakes, hurricanes, floods or other natural disasters; (i) changes in applicable law or GAAP (or the interpretation thereof); or (j) any action made or initiated by any SSGT or SST II stockholder, as the case may be, including any derivative claims, arising out of or relating to the Merger Agreement or the transactions contemplated by the Merger Agreement; which in the case of each of (b)-(e) and (h)-(i) above do not disproportionately affect SSGT or SST II (and their respective subsidiaries), taken as a whole, relative to others in the self-storage industry in the geographic regions in which SSGT or SST II (and their respective subsidiaries) operate.

Covenants and Agreements

Conduct of SSGT’s Business Pending the REIT Merger.SSGT has agreed to certain restrictions on itself and its subsidiaries until the earlier of the effective time of the REIT Merger or the valid termination of the Merger Agreement. In general, except with SST II’s prior written approval (not to be unreasonably withheld, delayed or conditioned) or as otherwise expressly required or permitted by the Merger Agreement or required by law, SSGT has agreed that it and SSGT OP will, and will cause each other SSGT subsidiary to, conduct its business in all material respects in the ordinary course and in a manner consistent with past practice and use all reasonable efforts to (1) maintain the condition of its materials assets and properties (normal wear and tear excepted), (2) preserve intact its current business organization, goodwill, ongoing businesses and significant relationships with third parties, (3) continue the development of any properties currently under construction in accordance with the applicable development agreements and budgets, and (4) maintain the status of SSGT as a REIT.

47

Without limiting the foregoing, SSGT has also agreed that, except with SST II’s prior written approval (not to be unreasonably withheld, delayed or conditioned), to the extent required by law or as otherwise expressly required or permitted by the Merger Agreement, SSGT and SSGT OP will not do, and will not cause or permit any other SSGT subsidiary to do, any of the following:

• sell, mortgage, pledge, lease, assign, transfer, dispose of or encumber, or effect a deed in lieu of foreclosure with respect to, any property or assets, except in the ordinary course of business consistent with past practice; provided, that (1) any sale, mortgage, pledge, lease, assignment, transfer, disposition or deed in connection with (a) the potential sale of the San Antonio Property (as defined in the Merger Agreement), (b) the satisfaction of any margin call or (c) the posting of collateral in connection with any contract to which SSGT or any SSGT subsidiary is a party, will be considered to be done in the ordinary course of business consistent with past practice, and (2) SSGT or any SSGT subsidiary is permitted to effect a deed in lieu of foreclosure if the failure to do so would result in personal or

48

• make any loans, advances or capital contributions to, or investments in, any other person (including to any of its officers, directors, affiliates, agents or consultants), make any change in its existing borrowing or lending arrangements for or on behalf of such persons, or enter into any “keep well” or similar agreement to maintain the financial condition of another entity, other than (1) by SSGT or a wholly-owned SSGT subsidiary to SSGT or a wholly-owned SSGT subsidiary and (2) investments permitted pursuant to the terms of the Merger Agreement;

• enter into, renew, modify, amend or terminate, or waive, release, compromise or assign any rights or claims under, any of SSGT’s material contracts, other than (1) any termination, renewal, modification or amendment in accordance with the terms of any such existing material contract (a) that occurs automatically without any action (other than notice of renewal) by SSGT or any SSGT subsidiary or (b) occurs in connection with the exercise by a third party of any preferential rights or options granted to such third party under the applicable material contract, or (2) as may be reasonably necessary to comply with the terms of the Merger Agreement;

• take any action that would, or fail to take any action, the failure of which to be taken would, reasonably be expected to cause SSGT to fail to qualify as a REIT or any SSGT subsidiary to cease to be treated as any of (1) a partnership or disregarded entity for federal income tax purposes or (2) a qualified REIT subsidiary or a taxable REIT subsidiary under the applicable provisions of Section 856 of the Code, as the case may be;

Notwithstanding anything to the contrary set forth above, nothing in the Merger Agreement prohibits SSGT from taking any action, at any time or from time to time, that in the reasonable judgment of our board of directors, upon advice of counsel to SSGT, is reasonably necessary (1) for SSGT to avoid or to continue to avoid incurring entity level income or excise taxes under the Code or to maintain its qualification as a REIT under the Code for any period or portion thereof ending on or prior to the effective time of the REIT Merger or (2) to establish or maintain any exemption from or otherwise avoid the imposition of any requirement that SSGT or any SSGT subsidiary be registered as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”), including in the case of clause (1) only, making dividend or any other actual, constructive or deemed distribution payments to SSGT stockholders.

Conduct of SST II’s Business Pending the REIT Merger.SST II has agreed that, until the earlier of the effective time of the REIT Merger or the valid termination of the Merger Agreement, SST II SST II OP and Merger Sub will not, and will not cause any other SST II subsidiary to, (1) take any action that is intended to or would result in any of the conditions to the Mergers becoming incapable of being satisfied, or (2) take any action

50

or fail to take any action that would, or would reasonably be expected to, prevent, materially delay or materially impede the ability of SSGT and Merger Sub to consummate the REIT Merger, or the ability of SSGT OP and SST II OP to consummate the Partnership Merger, or the ability of SST II, SST II OP, Merger Sub, SSGT or SSGT OP to complete the other transactions contemplated by the Merger Agreement.

However, nothing in the Merger Agreement prohibits SST II from taking any action, at any time or from time to time, that in the reasonable judgment of the SST II board of directors, upon advice of counsel to SST II, is reasonably necessary (1) for SST II to avoid or to continue to avoid incurring entity level income or excise taxes under the Code or to maintain its qualification as a REIT under the Code for any period or portion thereof ending on or prior to the effective time of the REIT Merger or (2) to establish or maintain any exemption from or otherwise avoid the imposition of any requirement that SST II or any SST II subsidiary be registered as an investment company under the Investment Company Act, including in the case of clause (1) only, making dividend or any other actual, constructive or deemed distribution payments to SST II stockholders.

No Solicitation of Transactions by SSGT. Pursuant to the terms of the Merger Agreement, until 11:59 p.m. (New York City time) on November 15, 2018 (the “Go Shop Period End Time”), SSGT had a “go shop” right that allowed SSGT and its subsidiaries to do the following:

• initiate, solicit, encourage or facilitate any inquiries or the making of any proposal, offer or other action that constitutes, or may reasonably be expected to lead to, any Acquisition Proposal (as defined below), including by way of contacting third parties, broadly disseminating public disclosure or providing access to the properties, offices, assets, books, records and personnel of SSGT and its subsidiaries and furnishingnon-public information pursuant to one or more acceptable confidentiality agreements; provided, however, that SSGT must have previously or contemporaneously furnished, made available or provided access to suchnon-public information to SST II;

• enter into, continue or otherwise participate in any discussions or negotiations with any person relating to, or in furtherance of such inquiries, proposals, offers or other actions or to obtain, an Acquisition Proposal;

• release any person from, or refrain from enforcing, any standstill agreement or similar obligation to SSGT or its subsidiaries; and

• disclose to SSGT stockholders any information required to be disclosed under applicable law.

Beginning at the Go Shop Period End Time, except as described below, the Merger Agreement provides that SSGT may not, and will cause its subsidiaries not to, do any of the following:

• initiate, solicit, knowingly encourage or facilitate any inquiries or the making of any proposal, offer or other action that constitutes any Acquisition Proposal;

• enter into, continue or otherwise participate in any discussions or negotiations with any person, or furnish to any person, anynon-public information, in furtherance of such inquiries or to obtain an Acquisition Proposal;

• release any person from or fail to enforce any standstill agreement or similar obligation to SSGT or its subsidiaries;

• make an Adverse Recommendation Change (as defined below);

• enter into any agreement in principle, arrangement, understanding, contract or agreement (whether binding or not) contemplating or otherwise relating to an Acquisition Proposal; or

• take any action to exempt any person from any takeover statute or similar restrictive provision of the SSGT charter and related documents.

Notwithstanding the foregoing, at any time up to five business days after the Go Shop Period End Time, the SSGT board of directors had the right, upon receipt of an Acquisition Proposal from a Go Shop Bidder (as

51

defined below) that constituted a Superior Proposal (as defined below), to give notice of its intention to terminate the Merger Agreement and enter into an agreement related to such Superior Proposal subject to the following conditions:

• the foregoing determination must have been made in good faith and upon the determination that failing to take such action would be inconsistent with the directors’ duties under applicable law;

• SSGT must have notified SST II in writing of the Superior Proposal, attaching the most current version of such proposal; and

• during the five business days after SST II received such notice, SSGT must have offered to negotiate with SST II (and negotiate in good faith) with respect to making adjustments to the terms of the Merger Agreement so that the subject Superior Proposal no longer was a Superior Proposal.

In addition, at any time beginning on the sixth business day after the Go Shop Period End Time but before receiving SSGT stockholder approval of the REIT Merger, the SSGT board of directors may, upon receipt of an Acquisition Proposal that constitutes a Superior Proposal, make an Adverse Recommendation Change and may terminate the Merger Agreement. There are several conditions to taking such action:

• the foregoing determination must be made in good faith and upon the determination that failing to take such action would be inconsistent with the directors’ duties under applicable law;

• SSGT must notify SST II in writing of the intent to make the Adverse Recommendation Change; and

• during the five business days after SST II has received such notice, SSGT must offer to negotiate with SST II (and negotiate in good faith) with respect to making adjustments to the terms of the Merger Agreement so that the subject Superior Proposal no longer is a Superior Proposal.

Likewise, at any time before receiving SSGT stockholder approval of the REIT Merger, the SSGT board of directors may, if it has determined in good faith that the failure to do so would be inconsistent with the directors’ duties under applicable law, make an Adverse Recommendation Change in response to an Intervening Event (as defined below).

The Merger Agreement also does not prevent the SSGT board of directors or SSGT, directly or indirectly, from (1) taking and disclosing to SSGT stockholders a position contemplated by Rule14d-9 or Rule14e-2(a) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), with respect to an Acquisition Proposal, making any required disclosure to SSGT stockholders under applicable law, includingRule 14d-9 promulgated under the Exchange Act or Item 1012(a) of RegulationM-A or (2) making any disclosure to SSGT stockholders if the SSGT board of directors determines in good faith (and based on the recommendation of the SSGT special committee after consultation with its legal advisors) that the failure to do so would be inconsistent with the directors’ duties under applicable law; provided, however, that to the extent any such disclosure addresses the approval, recommendation or declaration of advisability by the SSGT board of directors with respect to the Merger Agreement or an Acquisition Proposal, such disclosure will be deemed to be an Adverse Recommendation Change if not accompanied by an express publicre-affirmation of the recommendation of the SSGT board of directors.

For purposes of the Merger Agreement:

“Acquisition Proposal” means any proposal or offer, whether in one transaction or a series of related transactions, relating to any (1) merger, consolidation, share exchange, business combination or similar transaction involving SSGT or any subsidiary of SSGT that would constitute a “significant subsidiary” (as defined in Rule1-02 of RegulationS-X), (2) sale or other disposition, by merger, consolidation, share exchange, business combination or any similar transaction, of any assets of SSGT or any of its subsidiaries representing 20% or more of the consolidated assets of SSGT and its subsidiaries, taken as a whole, (3) issue, sale or other disposition by SSGT or any of its subsidiaries of (including by way of merger, consolidation, share exchange,

52

business combination or any similar transaction) securities (or options, rights or warrants to purchase, or securities convertible into, such securities) representing 20% or more of the votes associated with the outstanding shares of SSGT common stock, (4) tender offer or exchange offer in which any person or “group” (as that term is defined under the Exchange Act) will acquire beneficial ownership, or the right to acquire beneficial ownership, of 20% or more of the votes associated with the outstanding shares of SSGT common stock, (5) recapitalization, restructuring, liquidation, dissolution or other similar type of transaction with respect to SSGT in which a third party will acquire beneficial ownership of 20% or more of the outstanding shares of SSGT common stock, or (6) transaction that is similar in form, substance or purpose to any of the foregoing transactions; provided, however, that the term “Acquisition Proposal” will not include (a) the Mergers or any of the other transactions contemplated by the Merger Agreement or (b) any merger, consolidation, business combination, reorganization, recapitalization or similar transaction solely among SSGT and one or more SSGT subsidiaries or solely among SSGT subsidiaries.

“Adverse Recommendation Change” means (1) the failure of the SSGT board of directors to recommend that the SSGT stockholders vote in favor of approval of the REIT Merger, the failure to include that recommendation in this proxy statement, or a withdrawal, modification or amendment of that recommendation in a manner adverse to SST II or (2) the approval, endorsement or recommendation of any Acquisition Proposal.

“Go Shop Bidder” means any person that submits a proposal or offer regarding an Acquisition Proposal not later than the Go Shop Period End Time that has not been withdrawn and that the SSGT special committee determines prior to the Go Shop Period End Time (or in the case of any Acquisition Proposal received less than five business days before the date of the Go Shop Period End Time, not later than five business days after the Go Shop Period End Time), has resulted in, or would be reasonably expected to result in, a Superior Proposal.

“Intervening Event” means a change in circumstances or development that materially affects the business, assets or operations of SSGT and its subsidiaries, taken as a whole, that was not known to or reasonably foreseeable by the SSGT board of directors prior to the execution of the Merger Agreement, which change in circumstances or development becomes known to the SSGT board of directors prior to the effective time of REIT Merger, provided that (1) the terms of any potential sale transaction relating in any way to the San Antonio Property and (2) receipt, existence or terms of an Acquisition Proposal or any matter relating thereto or consequence thereof, will not constitute an Intervening Event.

“Superior Proposal” means a written Acquisition Proposal made by a third party (except for purposes of this definition, the references in the definition of “Acquisition Proposal” to “20%” will be replaced with “50%”) which the SSGT board of directors (based on the recommendation of the SSGT special committee after consultation with its legal and financial advisors) determines in its good faith judgment (after taking into account (1) all of the terms and conditions of the Acquisition Proposal and the Merger Agreement (as it may be proposed to be amended by SST II) and (2) the feasibility and certainty of consummation of such Acquisition Proposal on the terms proposed (taking into account all legal, financial, regulatory and other aspects of such Acquisition Proposal and conditions to consummation thereof)) to be more favorable from a financial point of view to SSGT stockholders (in their capacities as stockholders) than the Mergers and the other transactions contemplated by the Merger Agreement (as it may be proposed to be amended by SST II)).

Proxy Statement; SSGT Stockholders Meeting.SSGT agreed to prepare and file with the SEC this proxy statement and to cause this proxy statement to be mailed to SSGT stockholders entitled to vote at the special meeting. SSGT also agreed to include in this proxy statement the SSGT board of directors’ recommendation that SSGT stockholders approve the REIT Merger and to use its reasonable best efforts to obtain SSGT stockholder approval.

Access to Information; Confidentiality.The Merger Agreement requires SSGT to afford SST II and its representatives, upon reasonable notice and during normal business hours, reasonable access to SSGT’s and its subsidiaries’ properties, books, contracts, personnel and records upon reasonable advance notice and during

53

normal business hours. SST II has agreed to hold, and to cause its representatives and affiliates to hold, anynon-public information in confidence to the extent required by the terms of an existing confidentiality agreement between SSGT and SST II.

Public Announcements.Each of the parties to the Merger Agreement has agreed, subject to certain exceptions, to consult with each other before issuing any press release or otherwise making any public statements or filings with respect to the Merger Agreement or any of the transactions contemplated by the Merger Agreement. In addition, none of the parties to the Merger Agreement will, subject to certain exceptions, issue any press release or otherwise make a public statement or filing without obtaining the other parties’ consent (not to be unreasonably withheld, conditioned or delayed).

Indemnification of Directors and Officers; Insurance.For a period of six years after the effective time of the Mergers, pursuant to the terms of the Merger Agreement and subject to certain limitations, SST II will, and will cause Merger Sub to, indemnify, advance expenses to, defend and hold harmless the Indemnified Parties for actions at or prior to the effective time of the REIT Merger, including with respect to the transactions contemplated by the Merger Agreement. SST II has agreed that all rights to indemnification and exculpation from liabilities for acts provided in (i) the governing documents of SSGT or similar organizational documents or agreements of any subsidiary of SSGT and (ii) any indemnification agreements of SSGT will survive the Mergers and will continue in full force and effect in accordance with their terms. For a period of six years after the effective time of the REIT Merger, the organizational documents of SST II and Merger Sub and the organizational documents of any other SST II subsidiary or SSGT subsidiary will not have indemnification and director and officer liability limitation provisions less favorable than such provisions in SSGT’s organizational documents.

SST II has agreed to cause Merger Sub, as the surviving entity of the REIT Merger, to maintain SSGT’s current directors’ and officers’ liability insurance policies for a period of six years after the effective time of the REIT Merger. However, in lieu of that obligation, (1) Merger Sub may substitute directors’ and officers’ liability insurance policies from one or more insurance carriers with terms and retentions that are no less favorable in the aggregate than the coverage provided under SSGT’s existing policies, or (2) SSGT may, in consultation with SST II, obtain extended reporting period coverage under SSGT’s existing insurance programs for a period of six years after the effective time of the REIT Merger. Notwithstanding the foregoing, (a) Merger Sub will not be required to pay annual premiums in excess of (for any one year) 300% of the annual premium currently paid by SSGT for such insurance, and (b) if the annual premiums exceed 300%, Merger Sub will be obligated to obtain a policy with the greatest coverage available for a cost not exceeding 300% of the current annual premium.

Appropriate Action; Consents; Filings.Both SSGT and SST II will, and will cause their respective subsidiaries to, use their reasonable best efforts (subject to certain limitations) to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other party in doing, all things necessary, proper or advisable under applicable law or pursuant to any contract to consummate and make effective, as promptly as practicable, the Mergers and the other transactions contemplated by the Merger Agreement, including:

• taking all actions necessary to satisfy the closing conditions set forth in the Merger Agreement;

• preparing and filing any applications, notices, registrations and requests as may be required or advisable to be filed with or submitted to any governmental authority or agency;

• obtaining all necessary or advisable actions or nonactions, waivers, consents and approvals from governmental authorities, agencies or other persons necessary in connection with the consummation of the Mergers and the other transactions contemplated by the Merger Agreement and the making of all necessary or advisable registrations and filings and the taking of all reasonable steps as may be necessary or advisable to obtain an approval or waiver from, or to avoid an action or proceeding by, any governmental authority or other persons necessary in connection with the consummation of the Mergers and the other transactions contemplated by the Merger Agreement;

54

• defending any lawsuits or other legal proceedings, whether judicial or administrative, challenging the Merger Agreement or the consummation of the Mergers or the other transactions contemplated by the Merger Agreement, including seeking to have any stay or temporary restraining order entered by any court or other governmental authority vacated or reversed, and the avoidance of each and every impediment under any antitrust, merger control, competition or trade regulation law that may be asserted by any governmental authority with respect to the Mergers so as to enable the closing to occur as soon as reasonably possible; and

• executing and delivering any additional instruments necessary or advisable to consummate the Mergers and the other transactions contemplated by the Merger Agreement and to fully carry out the purposes of the Merger Agreement.

Neither party will have any obligation (1) to propose, negotiate, commit to or effect, by consent decree, hold separate order or otherwise, the sale, divestiture or disposition of any assets or businesses of such party, any of its subsidiaries (including SST II subsidiaries after the closing) or their affiliates or (2) otherwise to take or commit to take any actions that would limit the freedom of such party, its subsidiaries (including SST II subsidiaries after the closing) or their affiliates with respect to, or their ability to retain, one or more of their businesses, product lines or assets.

Termination of the Merger Agreement

Termination by Mutual Agreement.SSGT and SST II (acting through their special committees) may, by written consent, mutually agree to terminate the Merger Agreement before completing the REIT Merger, even after approval of the REIT Merger by the stockholders of SSGT.

Termination by Either SST II or SSGT. The Merger Agreement may also be terminated prior to the effective time of the REIT Merger by either SST II or SSGT (acting through their special committees) if any of the following occur:

(1) the REIT Merger has not occurred on or before April 1, 2019, except that the right to terminate for this reason will not be available to SSGT or SST II, as applicable, if the failure of that party to perform or comply in all material respects with its obligations under the Merger Agreement caused the failure of the REIT Merger to occur by that outside date;

(2) a final,non-appealable order has been issued by a governmental authority that permanently restrains or otherwise prohibits the transactions contemplated by the Merger Agreement, except that the right to terminate for this reason will not be available to SSGT or SST II, as applicable, if the issuance of such order was primarily due to the failure of that party to perform or comply in all material respects with its obligations under the Merger Agreement; or

(3) SSGT stockholder approval of the REIT Merger has not been obtained at the SSGT stockholder special meeting, except that the right to terminate for this reason will not be available to SSGT or SST II if such failure was primarily due to the failure of that party to perform or comply in all material respects with its obligations under the Merger Agreement.

Termination by SSGT.The Merger Agreement may also be terminated prior to the effective time of the REIT Merger by SSGT (with the prior approval of the SSGT special committee) upon any of the following:

(1) SST II has breached or failed to perform any of its representations, warranties, obligations, covenants or agreements set forth in the Merger Agreement that would cause a condition to closing not to be satisfied, which breach or failure to perform cannot be cured or, if capable of cure, has not been cured by the earlier of 20 business days following notice from SSGT to SST II or March 28, 2019; provided, that SSGT does not have the right to terminate the Merger Agreement for such a breach if SSGT has similarly breached or failed to perform any of its representations, warranties, obligations, covenants or agreements in the Merger Agreement;

57

(2) SSGT has accepted a Superior Proposal by a Go Shop Bidder within five business days of the Go Shop Period End Time, provided SSGT must, concurrently with the termination of the Merger Agreement, make the termination payment required by the Merger Agreement (and described below) to SST II and enter into a definitive agreement relating to the Superior Proposal;

(3) SSGT has accepted a Superior Proposal at any time beginning on the sixth business day after the Go Shop Period End Time and prior to receipt of SSGT stockholder approval of the REIT Merger, provided SSGT must, concurrently with the termination of the Merger Agreement, make the termination payment required by the Merger Agreement (and described below) to SST II and enter into a definitive agreement relating to the Superior Proposal;

(4) an Intervening Event has occurred prior to SSGT stockholder approval of the REIT Merger, and the SSGT board of directors has determined in good faith (based on the recommendation of the SSGT special committee after consultation with its legal and financial advisors) that the failure to terminate the Merger Agreement would be inconsistent with the directors’ duties under applicable law; or

(5) if (a) all of SST II’s conditions to closing have been and continue to be satisfied or waived (other than those conditions that by their nature cannot be satisfied other than at closing), (b) SSGT has confirmed by written notice to SST II that all of SSGT’s conditions to closing have been satisfied or waived (other than those conditions that by their nature cannot be satisfied other than at closing) and that SSGT is prepared to consummate the Mergers, and (c) SST II, SST II OP and Merger Sub then fail to consummate the Mergers and the other transactions contemplated by the Merger Agreement within four business days following SSGT’s written notice.

Termination by SST II.The Merger Agreement may also be terminated prior to the effective time of the REIT Merger by SST II (with the prior approval of the SST II special committee), upon any of the following:

(1) SSGT has breached or failed to perform any of its representations, warranties, obligations, covenants or agreements set forth in the Merger Agreement that would cause a condition to closing not to be satisfied, which breach or failure to perform cannot be cured or, if capable of cure, has not been cured by the earlier of 20 business days following notice from SSGT to SST II or March 28, 2019; provided, that SST II does not have the right to terminate the Merger Agreement for such a breach if SST II has similarly breached or failed to perform any of its representations, warranties, obligations, covenants or agreements in the Merger Agreement; or

(2) at any time following the date that is five business days after the Go Shop Period End Time and prior to SSGT stockholder approval of the REIT Merger if:

• the SSGT board of directors or any committee thereof, for any reason, has effected an Adverse Recommendation Change;

• the SSGT board of directors or any committee thereof has approved, adopted or publicly endorsed or recommended any Acquisition Proposal;

• a tender offer or exchange offer for any shares of SSGT common stock that constitutes an Acquisition Proposal (other than by SST II or any of its affiliates) has been commenced and the SSGT board of directors has failed to recommend against acceptance of such tender offer or exchange offer by SSGT stockholders and to publicly reaffirm the recommendation of the SSGT board of directors in favor of the REIT Merger within 10 business days of being requested to do so by SST II;

• the SSGT board of directors or any committee thereof has failed to include the recommendation of the SSGT board of directors in favor of the REIT Merger in this proxy statement; or

• SSGT has materially violated any of its obligations under the go shop provisions of the Merger Agreement (other than any immaterial or inadvertent violations that did not result in an alternative Acquisition Proposal).

58

• a termination fee of $2.9 million if SSGT terminates the Merger Agreement pursuant to item (2) under “—Termination by SSGT” above;

• the Merger Agreement (a) is terminated by SSGT or SST II because the SSGT stockholders did not approve the REIT Merger and, prior to the SSGT special meeting, a bona fide Acquisition Proposal was publicly announced or communicated to the SSGT stockholders, and (b) within 12 months after the date of such termination, a transaction with respect to such Acquisition Proposal is consummated or SSGT enters into a definitive agreement in respect of an Acquisition Proposal that is later consummated;

• the Merger Agreement is terminated by SSGT pursuant to item (5) under “—Termination by SSGT” above; or

• the Merger Agreement is terminated by SST II pursuant to item (1) under “—Termination by Either SST II or SSGT” above, but at the time of termination SSGT would have been entitled to terminate the Merger Agreement pursuant to item (5) under “—Termination by SSGT” above; and

• an expense reimbursement of up to $2.0 million if the Merger Agreement is terminated by SSGT pursuant to item (1) under “—Termination by SSGT” above.

Miscellaneous Provisions

Payment of Expenses.Other than as described above under “Termination Fees and Expense Reimbursement,” the Merger Agreement provides that all expenses will be paid by the party incurring such fees or expenses, whether or not the Mergers are consummated. In the event the Mergers are consummated, SST II has agreed to pay any expenses of SSGT that are not paid by SSGT prior to the Mergers.

Specific Performance.The parties to the Merger Agreement are entitled to seek injunctions, specific performance and other equitable relief to prevent breaches of the Merger Agreement and to specifically enforce the terms and provisions of the Merger Agreement, in addition to any and all other remedies at law or in equity.

59

Amendment.The parties to the Merger Agreement may amend the Merger Agreement by an instrument in writing signed by each of the parties, provided that, after SSGT stockholder approval of the REIT Merger, no amendment may be made which by law requires further approval by SSGT stockholders, without the approval of the SSGT stockholders.

Waiver.Prior to the effective time of the REIT Merger, the parties may extend the time for performance of any obligation of the other party or waive any inaccuracy in the representations and warranties of the other party or the other party’s compliance with any agreement or condition contained in the Merger Agreement to the extent permitted by law.

Governing Law. The Merger Agreement is governed by the laws of the State of Maryland (without giving effect to choice of law principles thereof).

APPROVAL FOR CERTAIN ADJOURNMENTS OF

THE SPECIAL MEETING

(PROPOSAL 2)

Although it is not currently expected, the special meeting may be adjourned for the purpose of soliciting additional proxies if we have not received sufficient votes for approval of the REIT Merger. Any adjournments may be made without notice, other than by an announcement at the special meeting, upon approval by stockholders by the affirmative vote of not less than a majority of the votes cast on the proposal.

If the persons named as proxies on the proxy card are asked to vote for one or more adjournments of the special meeting to permit further solicitation of proxies if there are not sufficient votes at the special meeting to approve the REIT Merger, they will only have the authority to vote on such matter as instructed by you or your proxy and, if no instructions are provided, will vote for such adjournment. Any adjournment of the special meeting for the purpose of soliciting additional proxies will allow our stockholders who have already granted their proxies to revoke them at any time prior to their use.

Our board of directors unanimously (with Mr. Schwartz abstaining) recommends a vote “FOR” the approval of adjournments of the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies.

NO APPRAISAL OR DISSENTERS’ RIGHTS

As permitted by the MGCL, our charter provides that stockholders are not be entitled to exercise any appraisal rights unless our board of directors, upon the affirmative vote of a majority of the board of directors, determines that such rights apply. Because our board of directors has not made such a determination, our stockholders are not entitled to exercise any appraisal rights in connection with the REIT Merger.

SUBMISSION OF STOCKHOLDER PROPOSALS

We intend to hold an annual meeting in 2019 only if the Mergers are not completed. In order for a stockholder proposal to be properly submitted for presentation at our 2019 annual meeting, we must receive written notice of the proposal at our executive offices during the period beginning on December 15, 2018 and ending January 14, 2019. If you wish to present a proposal for inclusion in the proxy materials for next year’s annual meeting, we must receive written notice of your proposal at our executive offices no later than December 15, 2018.

Proposals should be sent via registered, certified or express mail to: Strategic Storage Growth Trust, Inc., Attention: James Berg, Secretary, 10 Terrace Road, Ladera Ranch, California 92694.

MULTIPLE STOCKHOLDERS SHARING AN ADDRESS

The SEC has adopted a rule concerning the delivery of documents filed by us with the SEC, including proxy statements, which allows us to send a single proxy statement to any household at which two or more stockholders reside if they share the same last name or we reasonably believe they are members of the same family. This procedure is referred to as “householding.” This rule benefits both you and us. It reduces the volume of duplicate information received at your household and helps us reduce expenses. Each stockholder subject to householding will continue to receive a separate proxy card or voting instruction card.

We will promptly deliver, upon written or oral request, a separate copy of this proxy statement to a stockholder at a shared address to which a single copy was previously delivered. If you received a single copy of this proxy statement, but you would prefer to receive your own copy, you may direct requests for separate copies to Strategic Storage Growth Trust, Inc., Attention: James L. Berg, 10 Terrace Road, Ladera Ranch, California 92694 or call us at (877)327-3485. Also, if your household currently receives multiple copies of disclosure documents and you would like to receive just one set, please contact us at the same address and phone number.

WHERE YOU CAN FIND MORE INFORMATION

We file annual, quarterly and current reports and proxy statements with the SEC. You may read and copy any reports, proxy statements or other information that we file with the SEC at the following location of the SEC:

Public Reference Room

Securities and Exchange Commission

100 F Street, N.E., Room 1580

and (ii) instructions for use in effecting the surrender of the Certificates or the transfer of Book-Entry Shares in exchange for the REIT Merger Consideration into which the number of shares of SSGT Common Stock previously represented by such Certificate or Book-Entry Share shall have been converted pursuant to this Agreement.

The Paying Agent shall accept such Certificates (or affidavits of loss in lieu thereof) and Book-Entry Shares upon compliance with such reasonable terms and conditions as the Paying Agent may impose to effect an orderly exchange thereof in accordance with customary exchange practices. Until surrendered or transferred as contemplated by thisSection 3.3, each Certificate or Book-Entry Share representing shares of SSGT Common Stock shall be deemed, at any time after the REIT Merger Effective Time, to represent only the right to receive, upon such surrender, the REIT Merger Consideration as contemplated by thisArticle III. No interest shall be paid or accrued for the benefit of holders of the Certificates or Book-Entry Shares on the REIT Merger Consideration payable upon the surrender of the Certificates or Book-Entry Shares.

(c)    In the event of a transfer of ownership of shares of SSGT Common Stock that is not registered in the transfer records of SSGT, it shall be a condition of payment that any Certificate or Book-Entry Share surrendered or transferred in accordance with the procedures set forth in thisSection 3.3 shall be properly endorsed or shall be otherwise in proper form for transfer, and that the Person requesting such payment shall have paid any Taxes required by reason of the payment of the REIT Merger Consideration to a Person other than the registered holder of the Certificate surrendered, or Book-Entry Share transferred, or shall have established to the reasonable satisfaction of SST II that such Tax either has been paid or is not applicable.

(d)    Any portion of the Exchange Fund that remains undistributed to the holders of SSGT Common Stock for twelve (12) months after the REIT Merger Effective Time shall be delivered to SST II upon demand, and any former holders of SSGT Common Stock prior to the REIT Merger who have not theretofore complied with thisArticle III shall thereafter look only to SST II for payment of their claims with respect thereto.

(e)    None of the SSGT Parties, the SST II Parties, the Surviving Entity, the Paying Agent, or any employee, officer, director, agent or Affiliate of such entities, shall be liable to any Person in respect of the REIT Merger Consideration if the Exchange Fund (or the appropriate portion thereof) has been delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. Any amounts remaining unclaimed by holders of any shares of SSGT Common Stock immediately prior to the time at which such amounts would otherwise escheat to, or become property of, any Governmental Authority shall, to the extent permitted by applicable Law, become the property of SST II free and clear of any claims or interest of such holders or their successors, assigns or personal representatives previously entitled thereto.

Section 3.4    Withholding Rights. Each Party (including the Surviving Entity and the Surviving Partnership) and the Paying Agent, as applicable, shall be entitled to deduct and withhold from the Merger Consideration and any other amounts otherwise payable pursuant to this Agreement to any holder of SSGT Common Stock or SSGT OP Units, such amounts as it is required to deduct and withhold with respect to such payments under the Code or any other provision of state, local or foreign Tax Law. Any such amounts so deducted and withheld shall be paid over to the applicable Governmental Authority in accordance with applicable Law and shall be treated for

A-16

all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

Section 3.5    SSGT Restricted Shares. Immediately prior to the REIT Merger Effective Time, each SSGT Restricted Share granted under the SSGT Equity Incentive Plan shall be fully vested andnon-forfeitable, and all SSGT Common Stock represented thereby shall be considered outstanding for all purposes of this Agreement and subject to the right to receive the REIT Merger Consideration, subject toSection 3.4.

Each SSGT Party and each other SSGT Subsidiary has duly paid (or there has been paid on their behalf), or made adequate provisions in accordance with GAAP for, all material Taxes required to be paid by them, whether or not shown on any Tax Return. No written claim has been proposed by any Governmental Authority in any jurisdiction where SSGT or any SSGT Subsidiary do not file Tax Returns that SSGT or any SSGT Subsidiary is or may be subject to Tax by such jurisdiction.

(b)    SSGT (i) for all taxable years commencing with SSGT’s year ending December 31, 2014 and through December 31, 2017, has been subject to taxation as a real estate investment trust (a “REIT”) under Sections 856 through 860 of the Code and has satisfied all requirements to qualify as a REIT for such years; (ii) has operated since January 1, 2014 to the date hereof, in a manner consistent with the requirements for qualification and taxation as a REIT; (iii) intends to continue to operate in such a manner as to qualify as a REIT for its taxable year that will include the day of the REIT Merger; and (iv) has not taken or omitted to take any action that could reasonably be expected to result in a challenge by the IRS or any other Governmental Authority to its status as a REIT, and no such challenge is pending or, to the Knowledge of SSGT, threatened.

A-26

(c)    At any time prior to the date that is five (5) Business Days after the Go Shop Period End Time, the SSGT Board may, if the SSGT Board determines in good faith (and based on the recommendation of the SSGT Special Committee after consultation with its legal advisor) that failing to do so would be inconsistent with the directors’ duties under applicable Law, upon receipt by SSGT of an Acquisition Proposal from a Go Shop Bidder that constitutes a Superior Proposal, give notice of its intention to terminate this Agreement pursuant toSection 9.1(c)(ii) and enter into an agreement related to such Superior Proposal,provided, that:

(i)    (A) such Acquisition Proposal did not result from SSGT’s material breach of its obligations under thisSection 7.3, and (B) the SSGT Board has determined in good faith (and based on the recommendation of the SSGT Special Committee after consultation with its legal and financial advisors) that such Acquisition Proposal constitutes a Superior Proposal and that the failure of SSGT to make an Adverse Recommendation Change would be inconsistent with the directors’ duties under applicable Law, taking into account all adjustments to the terms of this Agreement that may be offered by SST II pursuant toSection 7.3(d)(iii);

(ii)    SSGT has notified SST II in writing that the SSGT Board intends to make an Adverse Recommendation Change (a “Adverse Recommendation Change Notice”); and

negotiated in good faith with), and shall have caused its respective financial and legal advisors to offer to negotiate with (and, if accepted, negotiate in good faith with), SST II in making adjustments to the terms and conditions of this Agreement such that in circumstances involving or relating to an Acquisition Proposal, the Superior Proposal ceases to be a Superior Proposal;provided that any change in the consideration offered or any other material amendment, supplement or modification to any Acquisition Proposal shall be deemed a new Acquisition Proposal and SSGT may not make an Adverse Recommendation Change unless SSGT has complied with the requirements of thisSection 7.3(d) with respect to each such new Acquisition Proposal including sending an Adverse Recommendation Change Notice with respect to each such new Acquisition Proposal (except that the new negotiation period under thisSection 7.3(d)(iii) shall be three (3) Business Days instead of five (5) Business Days). Notwithstanding anything in thisSection 7.3(d)(iii), SST II’s rejection of SSGT’s offer to negotiate pursuant to thisSection 7.3(d)(iii) shall not have any bearing on SST II’s right to terminate this Agreement pursuant toSection 9.1(d)(ii) herein.

(e)    At any time prior to receipt of the Stockholder Approval and subject toSection 7.1(c), the SSGT Board may, if the SSGT Board determines in good faith (and based on the recommendation of the SSGT Special Committee after consultation with its legal advisor) that the failure to do so would be inconsistent with the directors’ duties under applicable Law, make an Adverse Recommendation Change in response to an Intervening Event.

(f)    Nothing in thisSection 7.3 or elsewhere in this Agreement shall prevent the SSGT Board or SSGT, directly or indirectly, from (i) taking and disclosing to the stockholders of SSGT a position contemplated by Rule14d-9 or Rule14e-2(a) promulgated under the Exchange Act with respect to an Acquisition Proposal, making any required disclosure to the stockholders of SSGT under applicable Law, including Rule14d-9 promulgated under the Exchange Act or Item 1012(a) of RegulationM-A or (ii) making any disclosure to the stockholders of SSGT if the SSGT Board determines in good faith (and based on the recommendation of the SSGT Special Committee after consultation with its legal advisors) that the failure to do so would be inconsistent with the directors’ duties under applicable Law;provided,however, that to the extent any such disclosure addresses the approval, recommendation or declaration of advisability by the SSGT Board with respect to this Agreement or an Acquisition Proposal, such disclosure shall be deemed to be an Adverse Recommendation Change if not accompanied by an express publicre-affirmation of the SSGT Board Recommendation.

(g)    For purposes of this Agreement:

(a)    Without limiting or being limited by the provisions of Section 7.7(b), during the period commencing as of the REIT Merger Effective Time and ending on the sixth (6th) anniversary of the REIT Merger Effective Time, SST II shall (and shall cause the Surviving Entity to): (i) indemnify, defend and hold harmless each Indemnified Party against and from any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any Action to the extent such Action arises out of or pertains to (A) any action or omission or alleged action or omission in such Indemnified Party’s capacity as a manager, director, officer, partner, member, trustee, employee or agent of SSGT or any of the SSGT Subsidiaries or (B) this Agreement or any of the transactions contemplated by this Agreement, including the Mergers; and (ii) pay in advance of the final disposition of any such Action the expenses (including reasonable attorneys’ fees and any expenses incurred by any Indemnified Party in connection with enforcing any rights with respect to indemnification) of any Indemnified Party without the requirement of any bond or other security, in each case to the fullest extent permitted by Law, but subject to SST II’s or the Surviving Entity’s receipt of an undertaking by or on behalf of such Indemnified Party to repay such amount if it shall ultimately be determined that such Indemnified Party is not entitled to be indemnified. Notwithstanding anything to the contrary set forth in this Agreement, SST II or the Surviving Entity, as applicable, (i) shall not settle or compromise or consent to the entry of any judgment or otherwise seek termination with respect to any claim, action, suit or proceeding against or investigation of any Indemnified Party for which indemnification may be sought under thisSection 7.7(a) without the Indemnified Party’s prior written consent unless such settlement, compromise, consent or termination includes an unconditional release of such Indemnified Party from all liability arising out of such claim, action, suit, proceeding or investigation, (ii) shall not be liable for any settlement effected without their prior written consent and (iii) shall not have any obligation hereunder to any Indemnified Party to the extent that a court of competent jurisdiction shall determine in a final andnon-appealable order that such indemnification is prohibited by applicable Law, in which case the Indemnified Party shall promptly refund to SST II or the Surviving Entity the amount of all such expenses theretofore advanced pursuant hereto.

A-46

(b)    Without limiting the foregoing, each of SST II and the Surviving Entity agrees that all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the REIT Merger Effective Time now existing in favor of the current or former managers, directors, officers, partners, members, trustees, employees, agents, fiduciaries or other individuals of SSGT or any of the SSGT Subsidiaries (the “Indemnified Parties”) as provided in (i) the SSGT Governing Documents or, if applicable, similar organizational documents or agreements of any SSGT Subsidiary (the “SSGT Organizational Documents”) or (ii) indemnification agreements of SSGT, shall survive the Mergers and shall continue in full force and effect in accordance with their terms. For a period of six (6) years following the REIT Merger Effective Time, the organizational documents of SST II and the Surviving Entity and the organizational documents of any applicable SST II Subsidiary or SSGT Subsidiary shall contain provisions no less favorable to the Indemnified Parties with respect to indemnification and limitations on liability than are set forth in the SSGT Organizational Documents, which provisions shall not be amended, repealed or otherwise modified for a period of six (6) years following the REIT Merger Effective Time in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the REIT Merger Effective Time, were Indemnified Parties, unless such modification shall be required by applicable Law and then only to the minimum extent required by applicable Law.

(c)    For a period of six (6) years after the REIT Merger Effective Time, SST II shall cause the Surviving Entity to maintain in effect SSGT’s current directors’ and officers’ liability insurance covering each Person currently covered by SSGT’s directors’ and officers’ liability insurance policies for acts or omissions occurring prior to and through the REIT Merger Effective Time;provided, that in lieu of such obligation, (i) the Surviving Entity may substitute therefor policies of an insurance company with the same or better rating as SSGT’s current insurance carrier the material terms of which, including coverage and amount, are no less favorable in any material respect to such directors and officers than SSGT’s existing policies as of the date hereof or (ii) in consultation with SST II, SSGT may obtain extended reporting period coverage under SSGT’s existing insurance programs (to be effective as of the REIT Merger Effective Time) for a period of six (6) years after the REIT Merger Effective Time for a cost not in excess of three times the current annual premiums for such insurance; andprovided,further, that in no event shall the Surviving Entity be required to pay annual premiums for insurance under thisSection 7.7(c) in excess of 300% of the most recent annual premiums paid by SSGT for such purpose, it being understood that if the annual premiums of such insurance coverage exceed such amount, the Surviving Entity shall nevertheless be obligated to provide such coverage as may be obtained for such 300% amount.

(d)    If SST II or the Surviving Entity or any of their respective successors or assigns (i) consolidates with or merges with or into any other Person and shall not be the continuing or surviving corporation, partnership or other entity of such consolidation or merger or (ii) liquidates, dissolves orwinds-up, or transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, as a condition to the consummation of any such transaction, the successors and assigns of SST II or the Surviving Entity, as applicable, shall assume the obligations set forth in thisSection 7.7.

(e)    SST II shall cause the Surviving Entity to pay all reasonable expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Party in enforcing the obligations provided in thisSection 7.7.

(f)    The provisions of thisSection 7.7 are intended to be for the express benefit of, and shall be enforceable by, each Indemnified Party (each of which is an intended third party beneficiary of thisSection 7.7), his or her heirs and his or her personal representatives, shall be binding on all successors and assigns of SSGT, SST II and the Surviving Entity and shall not be amended in a manner that is adverse to the Indemnified Party (including his or her successors, assigns and heirs) without the prior written consent of the Indemnified Party (including such successors, assigns and heirs) affected thereby. The exculpation and indemnification provided for by thisSection 7.7 shall not be deemed to be exclusive of any other rights to which an Indemnified Party is entitled, whether pursuant to applicable Law, Contract or otherwise.

A-47

Section 7.8    Dividends. In the event that a distribution with respect to the shares of SSGT Common Stock permitted under the terms of this Agreement has a record date prior to the REIT Merger Effective Time and has not been paid prior to the Closing Date, such distribution shall be paid to the holders of such shares of SSGT Common Stock on the Closing Date immediately prior to the REIT Merger Effective Time.

Section 7.9    Takeover Statutes. The Parties shall use their respective reasonable best efforts (a) to take all action necessary so that no Takeover Statute is or becomes applicable to the Mergers or any of the other transactions contemplated by this Agreement and (b) if any such Takeover Statute is or becomes applicable to any of the foregoing, to take all action necessary so that the Mergers and the other transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to eliminate or minimize the effect of such Takeover Statute or the restrictions in the SSGT Charter or the SST II Charter (“Charter Restrictions”) on the Mergers and the other transactions contemplated by this Agreement. No Party shall take any action to exempt any Person (other than the other Parties or their respective Affiliates) from any Takeover Statute of any jurisdiction or the Charter Restrictions that may purport to be applicable to the Mergers or any of the other transactions contemplated by this Agreement or otherwise cause any restrictions in any Takeover Statute or the Charter Restrictions not to apply to any such Person.

For the avoidance of doubt, the foregoing shall not require the settlement or termination of an agreement that is solely between SSGT and/or any entities that will remain SSGT Subsidiaries after the Closing.

(b)    SSGT shall take all actions necessary to terminate, effective as of or prior to the Closing, the SSGT Equity Incentive Plan.

(c)    SSGT shall take all actions necessary to terminate, effective as of or prior to the Closing, the SSGT DRIP and the SSGT Share Redemption Program.

(iii)    by SSGT pursuant toSection 9.1(c)(ii), then SSGT shall pay to SST II an amount equal to the Go Shop Termination Payment.

A-53

(ix)    by SST II pursuant toSection 9.1(b)(i) and at the time of such termination SSGT would have been entitled to terminate this Agreement pursuant toSection 9.1(c)(v), then SST II shall pay to SSGT an amount equal to the SST II Termination Payment.

(c)    The Parties agree and acknowledge that in no event shall any Party be required to pay a Termination Payment on more than one occasion. Payment of a Termination Payment shall be made by wire transfer of same day funds to the account or accounts designated by the Party entitled to payment thereof (the “Recipient”) (i) prior to or concurrently at the time of consummation of any transaction contemplated by an Acquisition Proposal, in the case of a Termination Payment payable pursuant toSection 9.3(b)(i), (ii) prior to or concurrently with termination of this Agreement, in the case of a Termination Payment payable pursuant toSection 9.3(b)(iii),Section 9.3(b)(iv) orSection 9.3(b)(v), (iii) concurrently with termination of this Agreement, in the case of a Termination Payment payable pursuant toSection 9.3(b)(ix), and (iv) as promptly as reasonably practicable after termination (and, in any event, within two (2) Business Days thereof), in the case of a Termination Payment payable pursuant to any other provision ofSection 9.3(b).

(d)    Notwithstanding anything in this Agreement to the contrary, in the event that a Termination Payment becomes payable, then such payment shall be the Recipient’s and its Affiliates’ sole and exclusive remedy as liquidated damages for any and all losses or damages of any nature against the Party obligated to pay the Termination Payment (the “Payor”) and its Subsidiaries and each of their respective Representatives in respect of this Agreement, any agreement executed in connection herewith, and the transactions contemplated hereby and thereby, including for any loss or damage suffered as a result of the termination of this Agreement, the failure of the Mergers to be consummated or for a breach or failure to perform hereunder (whether intentionally, unintentionally, or otherwise) or otherwise.

(e)    Each of the Parties acknowledges that the agreements contained in thisSection 9.3 are an integral part of the transactions contemplated by this Agreement, and that without these agreements, the other Parties would not enter into this Agreement. In the event that the Payor shall fail to pay the Termination Payment when due, the Payor shall reimburse the Recipient for all reasonable costs and expenses actually incurred or accrued by the Recipient (including reasonable fees and expenses of counsel) in connection with the collection under and enforcement of thisSection 9.3. Further, if the Payor fails to timely pay any amount due pursuant to thisSection 9.3, and, in order to obtain the payment, the Recipient commences a suit which results in a judgment against the Payor for the payment set forth in thisSection 9.3, the Payor shall pay to the Recipient its reasonable and documented costs and expenses (including reasonable and documented attorneys’ fees) in connection with such suit, together with interest on such amount at a rate per annum equal to the prime rate of Citibank, N.A. in effect on the date such payment was required to be made through the date of payment. If payable, the Termination Payment shall not be payable more than once pursuant to this Agreement.

(f)    The Payor shall deposit into escrow an amount in cash equal to the Termination Payment with an escrow agent reasonably selected by the Recipient, after reasonable consultation with the Payor, and pursuant to a written escrow agreement (the “Escrow Agreement”) reflecting the terms set forth in thisSection 9.3(f) and otherwise reasonably acceptable to each of the Parties and the escrow agent. The payment or deposit into escrow of the Termination Payment pursuant to thisSection 9.3(f) shall be made by the Payor promptly after receipt of notice from the Recipient that the Escrow Agreement has been executed by the parties thereto. The Escrow Agreement shall provide that the Termination Payment in escrow or the applicable portion thereof shall be released to the Recipient on an annual basis based upon the delivery by the Recipient to the escrow agent of any one (or a combination) of the following:

(i)    a letter from the Recipient’s independent certified public accountants indicating the maximum amount that can be paid by the escrow agent to the Recipient without causing the Recipient to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code for the applicable taxable year of the Recipient determined as if the payment of such amount did not constitute income described in Sections 856(c)(2)(A)-(H) or 856(c)(3)(A)-(I) of the Code (such income, “Qualifying REIT

A-54

Income”), in which case the escrow agent shall release to the Recipient such maximum amount stated in the accountant’s letter;

(ii)    a letter from the Recipient’s counsel indicating that the Recipient received a private letter ruling from the IRS holding that the receipt by the Recipient of the Termination Payment would either constitute Qualifying REIT Income or would be excluded from gross income within the meaning of Sections 856(c)(2) and (3) of the Code, in which case the escrow agent shall release to the Recipient the remainder of the Termination Payment; or

(iii)    a letter from the Recipient’s counsel indicating that the Recipient has received a tax opinion from the Recipient’s outside counsel or accountant, respectively, to the effect that the receipt by the Recipient of the Termination Payment should either constitute Qualifying REIT Income or should be excluded from gross income within the meaning of Section 856(c)(2) and (3) of the Code, in which case the escrow agent shall release to the Recipient the remainder of the Termination Payment.

The Parties agree to cooperate in good faith to amend thisSection 9.3(f) at the reasonable request of the Recipient in order to (A) maximize the portion of the Termination Payment that may be distributed to the Recipient hereunder without causing the Recipient to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code, (B) improve the Recipient’s chances of securing the favorable private letter ruling from the IRS described in thisSection 9.3(f) or (C) assist the Recipient in obtaining the favorable tax opinion from its outside counsel or accountant described in thisSection 9.3(f). The Escrow Agreement shall provide that the Recipient shall bear all costs and expenses under the Escrow Agreement and that any portion of the Termination Payment held in escrow for ten (10) years shall be released by the escrow agent to the Payor. The Payor shall not be a party to the Escrow Agreement and shall not bear any liability, cost or expense resulting directly or indirectly from the Escrow Agreement (other than any Taxes imposed on the Payor in connection therewith). The Recipient shall fully indemnify the Payor and hold the Payor harmless from and against any such liability, cost or expense.

Section 9.4    Amendment. Subject to compliance with applicable Law, this Agreement may be amended by mutual agreement of the Parties by action taken or authorized by the SSGT Board (with the prior approval of the SSGT Special Committee) and the SST II Board (with the prior approval of the SST II Special Committee), respectively, at any time before or after receipt of the Stockholder Approval and prior to the REIT Merger Effective Time;provided, that after the Stockholder Approval has been obtained, there shall not be (i) any amendment of this Agreement that changes the amount or the form of the consideration to be delivered under this Agreement to the holders of SSGT Common Stock, or which by applicable Law requires the further approval of the stockholders of SSGT without such further approval of such stockholders, or (ii) any amendment or change not permitted under applicable Law. This Agreement may not be amended except by an instrument in writing signed by each of the Parties.

Section 10.3    Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced under any present or future Law, or public policy, (a) such term or other provision shall be fully separable, (b) this Agreement shall be construed and enforced as if such invalid, illegal or unenforceable provision had never comprised a part hereof, and (c) all other conditions and provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable term or other provision or by its severance herefrom so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that transactions contemplated by this Agreement be consummated as originally contemplated to the fullest extent possible.

Section 10.4    Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original and all of which together shall be deemed one and the same agreement, and shall become effective when one or more counterparts have been signed by each of the Parties and delivered (by telecopy, electronic delivery or otherwise) to the other Parties. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document form” (“pdf”), or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature.

Section 10.5    Entire Agreement; No Third-Party Beneficiaries. This Agreement (including the Exhibits, the Schedules, the SSGT Disclosure Letter and the SST II Disclosure Letter) and the Confidentiality Agreement (a) constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, between the Parties with respect to the subject matter of this Agreement and, (b) except for the provisions ofArticle III (which (i) from and after the REIT Merger Effective Time shall be for the benefit of holders of shares of SSGT Common Stock immediately prior to the REIT Merger Effective Time, and (ii) from and after the Partnership Merger Effective Time shall be for the benefit of holders of SSGT OP Units and the holder of the SSGT Special Limited Partner Interest immediately prior to the Partnership Merger Effective Time) andSection 7.7 (which, from and after the REIT Merger Effective Time shall be for the benefit of the Indemnified Parties), are not intended to confer upon any Person other than the Parties hereto any rights or remedies.

Section 10.6    Extension; Waiver.

Any agreement on the part of SSGT or SST II, as applicable, to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. The failure of any Party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

(a)    Except to the extent that the Laws of the State of Delaware are mandatorily applicable to the Partnership Merger, this Agreement, and all claims or causes of actions (whether at Law, in contract or in tort) that may be based upon, arise out of or related to this Agreement or the negotiation, execution or performance of this Agreement, shall be governed by, and construed in accordance with, the laws of the State of Maryland without giving effect to its conflicts of laws principles (whether the State of Maryland or any other jurisdiction that would cause the application of the Laws of any jurisdiction other than the State of Maryland).

(b)    Any and all disputes arising out of or relating to this Agreement or the transactions contemplated hereby shall be heard and determined exclusively in a Maryland state or federal court located in Baltimore City

A-57

exercising jurisdiction over the subject matter of such dispute(s).

Each of the Parties agrees that a final judgment in any such dispute shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law and (vii) agrees, with respect to any such action filed in such Maryland state court, to jointly request an assignment to the Maryland Business and Technology Case Management Program. Each Party irrevocably consents to service of process in the manner provided for notices inSection 10.2.

Section 10.9    Specific Performance. The Parties agree that irreparable harm would occur to thenon-breaching party if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy in the event of a breach.

The Special Committee of the Board of Directors

The Board of Directors

Strategic Storage Growth Trust, Inc.

10 Terrace Road

Ladera Ranch, California 92694

Ladies and Gentlemen:

The Special Committee of the Board of Directors of Strategic Storage Growth Trust, Inc. (“SSGT”) has requested our opinion as to the fairness, from a financial point of view, to the unaffiliated holders (as defined below) of common shares of SSGT, of the consideration to be paid to these holders pursuant to the Agreement and Plan of Merger dated October 1, 2018 (the “Merger Agreement”) to be entered into among Strategic Storage Trust II, Inc., a Maryland corporation (“SST II”), Strategic Storage Operating Partnership II, L.P., a Delaware limited partnership and the operating partnership of SST II (“SST II Operating Partnership”), SST II Growth Acquisition, LLC, a Maryland limited liability company and a wholly owned subsidiary of SST II (“Merger Sub”), SSGT, and SS Growth Operating Partnership, L.P., a Delaware limited partnership and the operating partnership of SSGT (“SSGT Operating Partnership”). As used in this opinion, “unaffiliated holders” means the holders of SSGT Common Stock (as defined below) other than SST II, Merger Sub, SmartStop Asset Management, LLC and their respective affiliates.

Pursuant to the Merger Agreement (i) SSGT will be merged with and into Merger Sub, with Merger Sub being the surviving company (the “REIT Merger”), and each share of the Class A common stock, $0.001 par value per share, of SSGT (the “SSGT Class A Common Stock”), and each share of the Class T common stock, $0.001 par value per share, of SSGT (the “SSGT Class T Common Stock” and, together with the SSGT Class A Common Stock, the “SSGT Common Stock”), issued and outstanding immediately prior to the REIT Merger will be converted into the right to receive $12.00 in cash per share (the “REIT Merger Consideration”); and (ii) SSGT Operating Partnership will be merged with SST II Operating Partnership, with SST II Operating Partnership being the surviving entity (the “Partnership Merger” and, together with the REIT Merger, the “Mergers”), and each unit of SSGT Operating Partnership (excluding certain special limited partner interests) issued and outstanding immediately prior to the Partnership Merger (the “SSGT OP Units”) will be converted into units of SSGT II Operating Partnership pursuant to the Merger Agreement. We are not providing any opinion with regard to the consideration paid in the Partnership Merger. The terms and conditions of the Mergers are more fully set forth in the Merger Agreement.

KeyBanc Capital Markets Inc. (“KBCM”), as part of its investment banking business, is customarily engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes.

In connection with rendering this opinion, we have reviewed and analyzed, among other things, the following: (i) an execution copy of the Merger Agreement; (ii) certain publicly available information concerning SSGT, including, but not limited to, its Annual Reports on Form10-K for the year ended December 31, 2017 and its quarterly reports for the quarters ended March 31, 2018 and June 30, 2018, in each case filed with the Securities and Exchange Commission; (iii) certain other internal information, primarily financial in nature, concerning the business and operations of SSGT furnished to us by SSGT for purposes of our analysis; (iv) certain publicly available information with respect to certain other companies that we believe to be comparable to SSGT; and (v) certain publicly available information and other information known to us concerning the nature and terms of certain other transactions that we consider relevant to our inquiry. We have also met with certain officers and employees of SSGT to discuss the business, financial condition, operations and

prospects of SSGT, as well as other matters we believed relevant to our inquiry. We have also performed such other financial studies and analyses and considered such other data and information as we deemed appropriate.

In our review and analysis and in arriving at our opinion, we have assumed and relied upon the accuracy and completeness of all of the financial and other information provided to or otherwise reviewed by or discussed with us or publicly available and have further relied upon the assurances of the management of SSGT that they are not aware of any facts or circumstances that would make such information inaccurate or misleading in any material respect. We have also assumed that the representations and warranties of each of the parties to the Merger Agreement are and will be true and correct in all respects material to our analysis. We have not been engaged to, and have not independently attempted to, verify any of such information or its accuracy or completeness. We have also relied upon the management of SSGT as to the reasonableness and achievability of the financial forecast (and the assumptions and bases therefor) provided to us and, with your consent, we have assumed that such forecast was reasonably prepared on bases that reflect the best currently available estimates and judgments of the management of SSGT of the future financial performance of SSGT and other matters covered thereby. We have not been engaged to assess the reasonableness or achievability of such forecast or the assumptions on which it was based, and we express no view as to such forecast or assumptions. In addition, we have not conducted a physical inspection, valuation or appraisal of any of the assets (including properties or facilities) or liabilities of SSGT. We are also not expressing any view or opinion with respect to, and, at your direction, we have relied upon, the assessments of representatives of SSGT regarding legal, regulatory, accounting, tax and similar matters relating to SSGT or the Mergers, as to which matters we understand that SSGT obtained such advice as it deemed necessary from qualified advisors and professionals. We have also assumed that all governmental, regulatory or other consents, releases and approvals necessary for the consummation of the Mergers will be obtained without any adverse effect on SSGT or the Mergers that would be meaningful to our analysis.

We have not been asked to, nor do we, offer any opinion as to the material terms of the Merger Agreement or the form of the Mergers. In rendering our opinion, we have assumed, with your consent, that the final executed form of the Merger Agreement will not differ in any material respect from the draft that we have examined, and that the conditions to the Mergers as set forth in the Merger Agreement will be satisfied and that the Mergers will be consummated on a timely basis on the terms set forth in the Merger Agreement without waiver, modification or amendment of any term or condition that would be meaningful to our analysis.

It should be noted that this opinion is based on economic and market conditions and other circumstances existing on, and information made available to us as of, the date hereof and does not address any matters subsequent to such date. In addition, our opinion is, in any event, limited to the fairness, as of the date hereof, from a financial point of view, of the consideration to be paid to the unaffiliated holders of common shares of SSGT pursuant to the Merger Agreement and does not address SSGT’s underlying business decision to engage in the Mergers or any other terms of the Mergers, including the merger consideration paid in the Partnership Merger, or the fairness of the Mergers, or any consideration paid in connection therewith, to creditors or other constituencies of SSGT. In addition, we do not express any opinion as to (i) the fairness of the Mergers or (ii) the amount or the nature of the compensation now paid or to be paid, in each case, to any of the directors, officers or employees of SSGT, or class of such persons, relative to the consideration to be paid to public shareholders of SSGT. We have not evaluated nor do we express any opinion on the solvency or viability of the parties to the Merger Agreement or their respective affiliates or the ability of such parties to pay their respective obligations when they come due. It should be noted that although subsequent developments may affect this opinion, we do not have any obligation to update, revise or reaffirm our opinion. This opinion has been approved by a fairness committee of KBCM.

We have acted as financial advisor to SSGT in connection with the Mergers and will receive from SSGT a fee for our services, a significant portion of which is contingent upon the consummation of the Mergers (the “Transaction Fee”). In addition, SSGT has agreed to reimburse us for certain expenses and to indemnify us under certain circumstances for certain liabilities that may arise out of our engagement. We also will receive a fee in connection with the delivery of this opinion, which fee will be credited against any Transaction Fee earned. We and our affiliates have performed banking and related services for SSGT during the past two calendar years

preceding the date hereof in the aggregate amount of approximately $400,000. In addition, we and our affiliates, including KeyBank N.A., which is the sole book runner, sole lead arranger and administrative agent under SST II’s existing amended and restated revolving credit facility, have previously provided commercial and investment banking services to SST II and have also received compensation from SST II during the past two calendar years preceding the date hereof in the aggregate amount of approximately $5.33 million. Given the existing relationship between KeyBank N.A. and SST II, it is likely that KeyBank N.A. will be asked to provide and will evaluate providing financing to SST II in connection with the Mergers. In the ordinary course of our businesses, we and our affiliates, employees of us and our affiliates, and funds or other entities that such persons manage or invest in or have other economic interests or with which theyco-invest, may at any time purchase, sell, hold or vote long or short positions and investments in securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments of SSGT or SST II, any of their respective affiliates and third parties, or any currency or commodity that may be involved in the Mergers, in each case for our own account or for the accounts of customers. We may in the future provide financial advisory and/or underwriting services to SSGT or SST II and their affiliates for which we may receive compensation.

It is understood that this opinion was prepared for the use of the Special Committee of the Board of Directors of SSGT and the SSGT Board of Directors in connection with and for the purpose of their evaluation of the proposed Mergers. This opinion letter is not to be used, circulated, quoted or otherwise referred to for any other purpose, nor is it to be filed with, included in or referred to in whole or in part in any registration statement, proxy statement or any other document, except in accordance with our prior written consent. Our opinion does not constitute a recommendation to any stockholder of SSGT as to how such stockholder should vote with respect to the Mergers or any other matter.

Based upon and subject to the foregoing, it is our opinion that as of the date hereof, the REIT Merger Consideration to be paid to the unaffiliated holders of common shares pursuant to the Merger Agreement is fair, from a financial point of view, to such holders.

Very truly yours,
