(herein called the "Corporation")

OF THE FIRST PART

OF THE SECOND PART
WHEREAS the Corporation and Executive entered into a Retention Agreement on
August 15, 2019 which shall be cancelled and replaced by this Amended and
Restated Retention Agreement (the “Agreement”).

WHEREAS the Executive currently serves as President – Virtualization &
Professional Services of the Corporation (the "Position");

AND WHEREAS in accordance with an employment letter dated January 25, 2017, the
Corporation agreed to provide the Executive with a retention bonus in the amount
of US$700,442 of which US$533,802 is unpaid (the “Outstanding Retention

is prepared to waive his entitlement to receive the Outstanding Retention
Payment and restructure such payment entitlement on the terms set forth in this
Agreement;

AND WHEREAS the Corporation considers the continuance of a sound and vital
management team of the Corporation to be essential to protecting and enhancing

    IN CONSIDERATION of the mutual covenants set out herein, the parties agree

2.
Ongoing Services

The Executive shall devote sufficient time and attention towards the interests
of the Corporation in connection with holding the Position. Without limiting the
generality of the foregoing, the Executive shall continue to perform all of his
responsibilities related to the Position in a diligent, faithful and
professional manner. Executive's resignation as the President of the Corporation
or from any other office for which he receives no compensation, or the
Corporation's removal or termination of Executive from any such position, shall
have no effect on this Agreement or the parties' obligations hereunder.

3.    Payment Upon a Change of Control

In the event of a Change of Control and provided no payment has been made under
Section 4, and provided that the Executive is employed by the Corporation
immediately prior to such Change of Control, then the Executive shall be
entitled, in his sole discretion, to receive the Outstanding Retention Payment
by providing written notice to the Corporation of his election to receive such
payment at any time within 30 days of such event. The Corporation covenants and
agrees to use its commercially reasonable efforts to provide the Executive with
written notice of a Change of Control.

For the purposes of this Agreement, a "Change of Control" means:

(a)    any "person" (as such term is used in Sections 13(d) and 14(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act")) becomes the
"beneficial owner" (as defined in Rule 13d-3 promulgated under the Exchange
Act), directly or indirectly, of securities of the Corporation representing
fifty (50%) percent or more of (i) the outstanding shares of common stock of the
Corporation, or (ii) the combined voting power of the Corporation’s outstanding
securities;

(b)    the Corporation is party to a merger or consolidation, or series of
related transactions, which results in the voting securities of the Corporation
outstanding immediately prior thereto failing to continue to represent (either
by remaining outstanding or by being converted into voting securities of the
surviving entity), directly or indirectly, at least fifty (50%) percent of the
combined voting power of the voting securities of the Corporation or such
surviving entity outstanding immediately after such merger or consolidation; or

(c)    the sale or disposition of all or substantially all of the Corporation’s
assets, or consummation of any transaction, or series of related transactions,
having similar effect (other than to a subsidiary of the Corporation).

4.    Accelerated Payment

If, prior to a Change of Control, Executive (a) becomes unable to provide
services to the Corporation, either due to prolonged sickness, permanent
disability or death, or (b) the Corporation terminates the Executive without
Cause (as defined below), or the Executive resigns his employment for Good
Reason (as defined below), then the Executive shall be entitled to receive the
Outstanding Retention Payment.

For purposes of this Agreement, "Good Reason" shall mean:

a)
any act, set of facts or omissions with respect to the Executive that would, as
a matter of applicable law, constitute a constructive termination of the
Executive;

b)
a change in the Executive’s position with the Corporation which results in a
material diminution of the Executive’s authority, duties, or responsibilities;

c)
a reduction by the Corporation in the annual rate of the Executive’s base salary
or, if applicable, target bonus opportunity, and in the event of a Change of
Control (as defined below), as compared to Executive’s base salary and target
bonus opportunity in effect immediately prior to the public announcement of the
Change of Control;

--------------------------------------------------------------------------------

d)
the failure of the Corporation (i) to continue to provide the Executive an
opportunity to participate in any benefit or compensation plans provided to
employees who hold positions with the Corporation comparable to the Executive’s
position, (ii) to provide the Executive all other fringe benefits (or the
equivalent) in effect for the benefit of any employee group which includes any
employee who hold a position with the Corporation comparable to the Executive’s
position, where in the event of a Change of Control, such comparison shall be
made relative to the time immediately prior to the public announcement of such
Change of Control); or (iii) continue to provide director’s and officers’
insurance;

e)
a change in the location of Executive's principal office to a different place
that is more than twenty-five miles from the Executive's principal office
immediately prior to such change;

f)
a restriction or prohibition on Executive’s participation in outside activities
that have historically been permitted, such as third-party board, committee,
panel, or association membership; or

g)
the Corporation's material breach of this Agreement, including, in the event of
a Change of Control, failure of the Corporation to obtain the consent of a
successor to perform all of the obligations of the Corporation under this
Agreement.

For purposes of this Agreement, "Cause" shall mean:

a)
the Executive willfully failed to follow the lawful written directions of the
Board of Directors of the Corporation or Executive’s immediate superior;
provided that no termination for such Cause shall occur unless the Executive:
(i) has been provided with notice, specifying such willful failure in reasonable
detail, of the Corporation’s intention to terminate the Executive for Cause; and
(ii) has failed to cure or correct such willful failure within thirty (30) days
of receiving such notice;

b)
the Executive engaged in gross misconduct, or gross incompetence which is
materially detrimental to the Corporation; provided that no termination for such
Cause shall occur unless the Executive: (i) has been provided with notice,
specifying such gross misconduct or gross incompetence in reasonable detail, of
the Corporation’s intention to terminate the Executive for Cause; and (ii) has
failed to cure or correct such gross misconduct within thirty (30) days of
receiving such notice;

c)
the Executive willfully failed to comply in any material respect with the
Corporation's policies where non-compliance would be materially detrimental to
the Corporation; provided that no termination for such Cause shall occur unless
the Executive: (i) has been provided with notice of the Corporation’s intention
to terminate the Executive for such Cause, and (ii) has failed to cure or
correct such willful failure within thirty (30) days of receiving such notice,
provided that such notice and cure period requirements shall not apply in the
event that such non-compliance is of a nature that it is unable to be remedied;
or

d)
the Executive is convicted of a felony or crime involving moral turpitude
(excluding drunk driving unless combined with other aggravating circumstances or
offenses) or commission of a fraud which the Corporation reasonably believes
would reflect adversely on the Corporation.
