Notwithstanding anything to the contrary above, at Subtenants option, Subtenant shall either pay the Monthly Rental
and any other sum due hereunder as rent, whether or not designated as rent, directly to the Prime Lessor at the address stated in the Prime Lease, or the Sublandlord at 173 Dufferin Street, Suite 200, Toronto, Ontario, M6K 3H7, Canada, Attn:
Facilities Manager; provided, however, that if Subtenant makes such payments directly to Prime Lessor, Subtenant shall provide Sublandlord with prior written notice that Subtenant will be making such direct payments. The reference 1144
Eastlake Softchoice/Zymo Sublease shall to be inserted on all rental checks. Subtenant shall pay the Monthly Rental in advance not later than the 1st day of every month during the Sublease Term. Subtenant may not change the party to whom
Subtenant pays the rent hereunder, without delivering prior written notice of such change to Sublandlord and in no event may such notice be given less than ten (10) business days prior to the date the next payment of rent is due under this
Lease.

(b) Additional Rent.Subtenant shall pay monthly as Additional Rent (i) the amount charged by the Prime
Lessor for 25 parking stalls pursuant to the Prime Leases paragraph 30 and its First Amendment at paragraph 2.9, currently at $125 per stall per month; and (ii) the amount Sublandlord is obligated to pay as its Pro Rata Share of Expenses,
Taxes and Insurance, as defined in paragraph 4.2 of the Prime Lease. The Subtenants Pro Rata Share is estimated in paragraph 1.4 of the Prime Lease (as amended by the First Amendment thereto) as 16.79%. As with the Monthly Rent, Subtenant may
elect to pay the Additional Rent directly to the Prime Lessor or to the Sublandlord; provided, however, that if Subtenant makes such payments directly to Prime Lessor, Subtenant shall provide Sublandlord with prior written notice that Subtenant will
be making such direct payments.

(c) Security Deposit.Subtenant agrees to pay Sublandlord $32,628.75 as security for
Subtenants payment of Monthly Rent and performance of its other obligations under this Sublease and any renewals or extensions of this Sublease. If Subtenant defaults in its payment of Monthly Rent or performance of its other obligations under
this Sublease, Sublandlord may use all or part of the security deposit for the payment of Monthly Rent or any other amount in default, or for the payment of any other amount that Sublandlord may spend or become obligated to spend by reason of
Subtenants default, or for the payment to Sublandlord of any other loss or damage that Sublandlord may suffer by reason of Subtenants default. If Sublandlord so uses any portion of the security deposit, Subtenant will restore the
security deposit to its original amount within five (5) days after written demand from Sublandlord. Sublandlord will not be required to keep the security deposit separate for its own funds and Subtenant will not be entitled to interest on the
security deposit. The security deposit will not be a limitation on Sublandlords damages or other rights under this Sublease, or a payment of liquidated damages, or an advance payment of the Monthly Rent. Upon expiration of the Sublease Term or
earlier termination of this Sublease the security deposit shall be returned to Subtenant within ten (10) days of such termination, reduced by such amounts as may be required by Sublandlord to remedy defaults on the part of Subtenant in the

HUNDRED THIRTY SIX and NO/100 Dollars ($40,236.00) (the Moving Allowance) as reimbursement for Sublandlords expenses incurred in moving from the Premises. Subtenant shall pay the Moving Allowance in a single sum, within thirty
(30) days following Subtenant receiving Sublandlords written demand for such payment; provided, however, in no event shall the Moving Allowance be payable prior to the Commencement Date, as the same may be extended pursuant to
Section 1(b) above.

3. Subordinate to Prime Lease, Sublandlord Covenants, Prime Lessor Agreement.

(a) Subordination. Subtenant acknowledges that it is familiar with the terms of the Prime Lease. Except as may be inconsistent with the terms
hereof, and subject to Sublandlord performing its covenants stated in Subsection 3(b) below, all the terms, covenants, restrictions and conditions in the Prime Lease contained as of the date of this Sublease, shall be applicable to this Sublease
with the same force and effect as if the Sublandlord were the lessor under the Prime Lease (except with respect to Prime Lessors obligations to provide services under the Prime Lease, as to which Section 6 hereof shall
prevail) and Subtenant were the lessee thereunder; and in the case of any breach hereof by Subtenant, Sublandlord shall have all the rights against Subtenant as would be available to Prime Lessor against Sublandlord as lessee
under the Prime Lease. Sections 6.1 and 6.2 of the Prime Lease are expressly inapplicable to this Sublease. This Sublease is in all respects subject to and subordinate to the terms and conditions of the Prime Lease. Except as expressly contradicted
by the terms of this Sublease, Subtenant agrees to be bound by all of the covenants, restrictions, terms and conditions of the Prime Lease in its use and occupancy of the Premises, and Subtenant covenants and agrees to perform all obligations of
Sublandlord arising under the Prime Lease during the term of this Sublease, and to refrain from violating or breaching any of the terms, covenants, restrictions and conditions of the Prime Lease.

(b) Sublandlord Covenants. Sublandlord hereby covenants and agrees for the Subtenants benefit as follows:

(i) To timely pay all Base Rent, Additional Rent and any other amounts due to Prime Lessor or otherwise under the Prime Lease (as these terms are defined
in the Prime Lease), except to the extent that Subtenant has notified Sublandlord that Subtenant is paying such sums directly to Prime Lessor;

(ii) Sublandlord will not exercise the renewal options presently provided for under Section 6.1 of the Prime Lease (which Section 6.1 of the Prime Lease is incorrectly referred to as Section 2.10 of the First Amendment);

---

(iii) Not to voluntarily cause, permit or consent to the early termination or alteration of the Prime
Lease, without first obtaining Subtenants consent which may be withheld in Subtenants sole discretion;

(iv) Subtenant shall and
may peacefully have, hold and enjoy the Premises free from any person claiming a right thereto through Sublandlord, subject to the terms of this Sublease and the Prime Lease, provided Subtenant pays the Monthly Rent and Additional Rent and fully
performs all of its covenants and agreements; and

(v) To immediately deliver to Sublandlord written copies of all notices it receives from
the Prime Lessor relating to the Premises, this Sublease or otherwise under the Prime Lease;

(vi) Upon request of Subtenant, to use every
reasonable effort to cause Prime Lessor to perform its obligations under the Prime Lease. Notwithstanding any limitation stated in the foregoing, Sublandlord shall commence legal action to compel Prime Lessor to cure its breach of the Prime Lease
(A) promptly after receiving a written request from the Subtenant when such breach materially interferes with Subtenants access to the Premises, use of the Premises or otherwise operating its business from the Premises; or (B) for
any other reason, promptly after receiving a written request from Subtenant, at Subtenants expense; provided, however, that Subtenant shall reimburse Sublandlord for its costs in connection therewith, but Subtenant shall be entitled to
reimbursement from Prime Lessor of such costs pursuant to the terms of the Prime Lease.

(c) Prime Lessors Agreement and
Representations. Prime Lessor agrees to concurrently deliver to Subtenant any notice it delivers to Sublandlord under the Prime Lease. Prime Lessor further agrees that, in the event of any termination of the Prime Lease, this Sublease shall
automatically become a direct lease under the same terms between Subtenant and the Prime Lessor, and by its execution of the consent below Prime Lessor agrees to such automatic agreement and non-disturbance of Subtenant so long as it is not in
default hereunder or under the Prime Lease, after the expiration of any applicable cure periods. Upon such direct lease, the Security Deposit held for Sublandlords behalf shall be deemed assigned to the Subtenant hereunder and Subtenant shall
have a claim for immediate reimbursement against Sublandlord for any shortfall between the amount of the assigned Security Deposit and the amount of the Security Deposit it paid over to Sublandlord pursuant to Subsection 2(c) above.

Prime Lessor further represents and warrants that, to the best of its knowledge, (i) neither Sublandlord or Landlord is in breach of or in default
under the Prime Lease and no event has occurred that, with notice and/or lapse of time, would constitute a breach or default by Sublandlord or Prime Lessor under the Prime Lease, and (ii) a true, correct, and complete copy of the Prime Lease
and the Storage Agreement as in effect on the Effective Date are attached hereto as Exhibits B-1 and B-2

4. Insurance. Subtenant shall
maintain at all times during the term of this Sublease, at its sole expense, the insurance required to be maintained by Sublandlord as lessee under the Prime Lease. All such insurance policies shall comply with all requirements of the



5



---

Prime Lease, and Subtenant shall deliver the certificate(s) of all such insurance to Sublandlord and to Prime Lessor prior to the Commencement Date and upon
request, at any time thereafter. The insurance certificates shall provide that such insurance shall not be cancelled or materially adversely amended without at least thirty (30) days prior written notice to Sublandlord and Prime Lessor.
Subtenant hereby expressly waives all rights of recovery which it might otherwise have against Sublandlord or Prime Lessor, for any loss or damage to personal property to the extent that such loss is covered, or would be covered by the insurance,
required by this Section 4, if it were in effect. Subtenant shall further cause its insurers to waive any right of subrogation that they might otherwise have against Sublandlord or Prime Lessor. Should premiums paid by the Sublandlord or Prime
Lessor increase due to Subtenants operations, the contents within the Premises or improvements made to the Premises, Subtenant shall promptly pay the increased amount of the premium upon request to Sublandlord or Prime Lessor, respectively.

5. As Is Condition; Use; Alterations.

(a) Condition. Subtenant shall take the Premises on an as is basis. As used herein as is means the condition the Premises and the Premises are in as of the execution date of this
Sublease, subject to ordinary wear and tear. Subtenants taking possession of any portion of the Premises shall be conclusive evidence against Sublandlord only that such portion of the Premises was in a good order and satisfactory condition
when Subtenant took possession. No promise of Sublandlord to alter, remodel, repair or improve the Premises and no representation respecting the condition of the Premises or the Building or any portion thereof have been made by Sublandlord to
Subtenant except as otherwise provided above in this Section 5. SUBLANDLORD HEREBY EXPRESSLY DISCLAIMS AND NEGATES, AND SUBTENANT HEREBY WAIVES, ALL WARRANTIES OF ANY KIND OR TYPE WHATSOEVER WITH RESPECT TO THE PREMISES, AND SUBTENANT AGREES
THAT PRIOR TO ACCEPTING THE PREMISES IT SHALL INSPECT AND BE SATISFIED WITH THE CONDITION AND FITNESS THEREOF AND ACCEPT THE SAME AS IS, WHERE IS AND WITH ALL FAULTS.

(b) Use.The Premises shall be used and occupied by Subtenant solely for the Permitted Uses under the Prime Lease, and for not other purpose unless
otherwise consented to by the Prime Lessor (the Sublandlords consent not being required). Subtenant covenants and agrees that it will, at its expense, comply with all laws, ordinances, orders, directions, requirements, rules and regulations of
all governmental authorities (including federal, state, county and municipal authorities), in force as of the Commencement Date or which may hereafter be in force, which shall impose any duty upon Prime Lessor, Sublandlord or Subtenant with respect
to the use, occupancy or alteration of the Premises and of all insurance bodies applicable to the Premises and to the Subtenants use or occupancy thereof. Subtenant shall not use or permit the use of the Premises in any manner that will
violate any of the terms or provisions of the Prime Lease.

---

(c) Alterations.Any alterations, additions or improvements desired by Subtenant shall be at
Subtenants sole cost and expense and must be first approved in writing by Prime Lessor, with the requirements for approvals, the standards and timetables therefore as set forth and pursuant to the provisions stated in the Prime Lease at
paragraph 9.3 therein, but with only the Prime Lessor and not the Sublandlord as the approving party. Any such additions, alterations or modifications shall be carried out by Subtenant, at its own expense, in accordance with the provisions of the
Prime Lease and Subtenants obligations to remove the same from the Premises at the expiration or earlier termination of this Sublease shall be in accordance with the terms of the Prime Lease. Subtenant shall indemnify and hold harmless
Sublandlord and Prime Lessor from any and all costs, expenses, claims or liabilities, incurred in connection with the installation by Subtenant of any additions, alterations or modifications to or of the Premises, except to the extent done at the
direction of the Sublandlord or Prime Lessor, or the result of the Sublandlords or the Prime Lessors gross negligence or intentional misconduct.

6. Services. Notwithstanding anything to the contrary contained herein, the only services or rights to which Subtenant is entitled hereunder are those to which Sublandlord is entitled to as lessee under the Prime
Lease and that for all such services and rights Subtenant will look to Prime Lessor under the Prime Lease. Except as expressly setforth in Section 3(b) above, and except for violating a covenant therein stated, nothing contained in this
Sublease shall in any way obligate Sublandlord to perform any act required to be performed by the Prime Lessor under the Prime Lease, nor shall Sublandlord incur any liability of Subtenant by virtue of the Prime Lessors failure to perform any
act required of it or Prime Lessors failure to give any consent under the Prime Lease. Sublandlord does, however, agree to use reasonable efforts to cause the Prime Lessor to provide the services required of Prime Lessor under the Prime Lease.

7. No Acts. Subtenant shall neither do nor permit anything to be done which would cause the Prime Lease to be terminated or forfeited or any
claims to accrue to the benefit of Prime Lessor by reasons of any right of termination or forfeiture reserved or vested in Prime Lessor under the Prime Lease, or any rights to damages accruing to or for the benefit of Prime Lessor under the Prime
Lease, and Subtenant shall indemnify and hold Sublandlord harmless from and against all loss, cost, damage or expense, including, but not limited to, attorneys fees and court costs, incurred by Sublandlord by reason of any breach by Subtenant
of any provision of this Lease or the Prime Lease (including, without limitation a breach which permits the Prime Lease to be terminated or forfeited). Sublandlord shall not be liable for damage to person or property sustained by Subtenant or any
other person, however such damage may have been caused, except to the extent resulting from the Sublandlords gross negligence or intentional misconduct.

8. Surrender. Upon the termination or expiration of this Sublease at any time and for any reason, Subtenant will immediately quit and peacefully surrender possession of the Premises and Subtenant agrees to return the Premises
in the same condition as they existed at the date of Subtenants occupancy, except for ordinary wear and tear and except for alterations and improvements approved by Prime Lessor (unless Prime Lessor, pursuant to the terms of the Prime Lease,
requires the removal of any alteration made by



7



---

Subtenant, in which event Subtenant shall remove the same and restore the Premises in accordance with the applicable provisions of the Prime Lease), and
Subtenant shall remove all of its personal property therefrom. If Subtenant remains in possession of the Premises after the end of the term of this Sublease then it will do so as a direct tenant of the Prime Lessor, on a month to month lease,
subject to all conditions, provisions and obligations of this Prime Lease in effect on the last day of the term.

9. No Assignment. Except as
otherwise expressly provided herein, Subtenant shall not assign this Sublease or any interest hereunder or further sublet all or any part of the Premises, or permit the use of the Premises by any party other than Subtenant and the employees of
Subtenant, without the prior written consent of Sublandlord and Prime Lessor in each instance, which will not be unreasonably withheld, conditioned or delay, all in accordance with the terms and conditions of Article 12 of the Prime Lease. Subtenant
shall not permit Subtenants interest in this Sublease to be vested in any third party by operation of law or otherwise. For purposes of this Section 9, an assignment of this Sublease shall be deemed to occur upon any change in the
ownership of Subtenant as described in Article 12 of the Prime Lease, provided howeverthat Subtenant shall be permitted to transfer this Sublease or its interest the Premises without obtaining Sublandlord or Prime Lessors consent for
those transfers described in the Prime Leases paragraph 12.5.

(ii) Subtenant shall fail to comply with any term, provision or covenant of the Prime Lease or this Sublease, other than a Monetary Default, and shall not
cure such failure within thirty (30) days after receipt of written notice thereof by Subtenant. However, if Subtenants failure to comply cannot reasonably be cured within thirty (30) days, then Subtenant shall be allowed additional
time as is reasonably necessary to cure the failure so long as Subtenant commences such cure within the initial 30 day period, and diligently prosecutes such cure thereafter.

(iii) Subtenant shall become insolvent, or shall make a transfer in order to defraud creditors or shall make an assignment for the benefit of creditors;

(iv) Subtenant shall file a petition under any section or chapter of the Federal Bankruptcy Code (11 U.S.C. §101 et.seq.), as

removed or dismissed within sixty (60) days;

(vi) Subtenant shall otherwise cause Sublandlord to be in default under the Prime Lease.

(b) Sublandlord Defaults.

(i)
Sublease Defaults. If Sublandlord breaches any covenant or agreement of this Sublease, then and in such event Subtenant shall have the right to execute and deliver to Sublandlord a written notice specifying such breach or the occurrence of
such event, and unless within ten (10) days from and after the date of delivery of such notice Sublandlord shall have commenced to remove or to cure such breach or occurrence and shall be proceeding with reasonable diligence to completely

equity, or under this Sublease (including, but not limited to, the right of specific performance, damages, or mandamus, but not the right to terminate this Sublease). All sums expended by Subtenant to cure any defaults of Sublandlord shall accrue
interest from the date of expenditure at the Default Rate and be payable within 15 days after demand and presentation of supporting documentation to Subtenant by Sublandlord. All amounts not paid when due shall continue to accrue interest at the

of the covenants required hereunder to be performed by Sublandlord and Subtenant, except the payment of rent and other sums to be paid by Subtenant hereunder.

12. Default Rate. Sublandlord and Subtenant further agree that in the event Subtenant at any time during the Sublease Term is in default in the payment of rent, Sublandlord shall have the right to charge interest at the rate
of twelve percent (12%) per annum or the highest rate allowed by law, whichever is lower (the Default Rate), which will accrue upon a Monetary Default and continuing until payments are current. Subtenant hereby agrees

either to person or property, sustained by Subtenant or by other persons, due to the Building or any part thereof or any appurtenances thereof becoming out of repair, or due to any act or neglect of any tenant or occupant of the Building, or any
other person, except to the extent caused by the gross negligence or willful misconduct of the party claiming the benefit of such release. To the fullest extent permitted by law, Subtenant shall protect, indemnify, defend and hold Sublandlord and
Prime Lessor and their respective officers, agents, servants and employees (collectively, the Indemnitees) harmless from and against any and all loss, costs, damages, claims, liabilities and expenses (including, without limitation, court
costs and attorneys fees) of whatever nature (collectively, Claims) arising from (i) injury to persons or damage to property on the Premises or in or about the Building arising out of or in connection with Subtenants use
or occupancy of the Premises or Subtenants activities in the Building, or arising from any act or negligence of Subtenant, or its agents, contractors, servants, employees or invitees, or (ii) failure of Subtenant to perform its
obligations under this Sublease, including those provisions of the Prime Lease incorporated herein by reference. Such indemnification, however, shall not apply to the extent the Claim arises from the gross negligence or intentional acts of any
Indemnitee. In case any action or proceeding be brought against any Indemnitee by reason of any such Claim, upon written notice to Subtenant, Subtenant covenants to resist and defend at Subtenants sole expense such action or proceeding by
counsel reasonably satisfactory to Sublandlord. The indemnification obligations hereunder shall survive the expiration or termination of this Sublease.

14.
Consent of Prime Lessor. This Sublease and the obligations of both parties hereunder, are conditioned upon the written consent of Prime Lessor under the Prime Lease as evidenced by Prime Lessors execution of the Prime
Lessors Consent on the signature page hereof. Further, any modifications or amendments to this Sublease shall not take effect or be binding upon Sublandlord until Sublandlord obtains the written consent of Prime Lessor and delivers a copy of
the same to Subtenant.
