Explanatory Note

This Amendment No. 9 ("Amendment No. 9") amends and supplements the statement on Schedule 13D initially filed with the SEC on February 1, 2017, as amended by:

	●	Amendment No. 1 filed on March 7, 2017,
	●	Amendment No. 2 filed on March 21, 2017,
	●	Amendment No. 3 filed on March 31, 2017,
	●	Amendment No. 4 filed on May 19, 2017,
	●	Amendment No. 5 filed on July 7, 2017,
	●	Amendment No. 6 filed on July 11, 2017,
	●	Amendment No. 7 filed on August 18, 2017, and
	●	Amendment No. 8 filed on March 30, 2018, (the initial filing and the first eight amendments, collectively, are the "Statement").

Amendment No. 9 is filed by the Reporting Persons with respect to the common shares, no par value (the "Common Shares"), of Sphere 3D Corp., an Ontario corporation (the "Issuer"). Capitalized terms used, but not otherwise defined, herein have the meanings ascribed to them in the Statement.

Item 4.

Purpose of Transaction.

Amendment No. 9 amends and supplements Item 4 of the Statement by deleting the disclosure under "Further Matters" and the adding the following in its place:

On December 20, 2018, MF Ventures filed a Form 144 with the SEC disclosing its intent to sell up to 60,000 Common Shares, and since December 21, 2018, MF Ventures has sold 5,754 Common Shares. Subject to applicable securities laws and regulations, market conditions and other factors, the Reporting Persons plan to sell Common Shares opportunistically, but reserve the right to acquire securities of the Issuer, including Common Shares. There can be no assurance, however, that any Reporting Person will take any such actions.

Notwithstanding anything in this Statement to the contrary, each Reporting Person specifically reserves the right to change its intention with respect to any and all matters disclosed or referenced herein. In reaching any decision with respect to any course of action, each Reporting Person expects it would take into consideration a variety of factors including, but not limited to, the Issuer's business and prospects, other business opportunities available to the Reporting Person, changes in applicable laws and regulations, general economic conditions, worldwide money and equity market conditions (including the market price of the securities of the Issuer), tax considerations, and any other factors deemed relevant. Further, the Reporting Persons intend to review their investment on a regular basis and, as a result of such review, may determine at any time or from time to time, either alone or as part of a group:

● to acquire additional securities of the Issuer through open market purchases, privately negotiated transactions, or otherwise;

● to dispose of all or a portion of the securities of the Issuer beneficially owned in the open market, privately negotiated transactions, or otherwise; or

● to take any other available course of action which may involve one or more of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D or have the results

CUSIP No. 8481L100

described in those subparagraphs.

Item 5.

Interest in Securities of the Issuer.

Amendment No. 9 amends and restates Item 5 of the Statement in its entirety as follows:

"(a) and (b)

Per the Schedule 14A filed with the SEC on November 28, 2018, the Issuer has 1,964,019 Common Shares issued and outstanding as of November 14, 2018 (the “Outstanding Shares”).

As of December 21, 2018, each Reporting Person may be deemed to beneficially own 281,067 Common Shares in the aggregate, which consists of: (i) 243,567 Common Shares issued to MF Ventures and (ii) 37,500 Common Shares issuable to MF Ventures under the August 2017 Warrants.

Further, as of December 21, 2018, each Reporting Person may be deemed to beneficially own 14.0% of the class of Common Shares, assuming 2,001,519 Common Shares outstanding, which consists of (i) the Outstanding Shares as of November 14, 2018 and (ii) the August 2017 Warrants.

No Reporting Person has the sole power to vote or direct the vote or sole power to dispose or direct the disposition of the Common Shares. Each Reporting Person has the shared power to vote or to direct the vote, or shared power to dispose or direct the disposition of the Common Shares.

Other than for purposes of Rule 13d-3, the foregoing statements will not be deemed to constitute an admission by each Reporting Person that the Reporting Person is the beneficial owner of any Common Shares disclosed under this Statement, and such beneficial ownership is expressly disclaimed.

(c)

The Reporting Persons have effected the following transactions in Common Shares in open market sales:

Date	No. of Common Shares Sold	Average Common Share Sale Price	Sale Price Range for Common Shares
12/20/18	5,754	$3.0823	$3.04-$3.10

(d)

None.

(e)

Not Applicable.”
