| | 4.6.2. | the Basic Salary
                                         of the Executive during the ensuing fiscal year; and
| | ------ | --------------------------------------------------------------------------------------------------------------



| | 4.6.3. | the potential

duties and responsibilities.

| | -- | --------



Executive will be entitled during
each Year of Employment during the Employment Period to accrue vacation time at the rate provided in Schedule

| | 7. | Termination
                                         of Employment
| | -- | ------------------------------------------------------------------



7.1. The
Corporation shall have the right to terminate the Executive’s employment with or without Just Cause, at any time and without
notice. The Executive shall have the right to resign for Good Reason by written notice of resignation delivered to the Board in
accordance with the definition of “Good Reason.” The Executive shall have the right to resign without Good Reason
by providing at least sixty (60) days written notice of the resignation delivered to the Corporation (provided that after Executive
has provided such notice to the Corporation, the Corporation may in its discretion shorten such notice period to a lesser duration
and in such case the Corporation would only have to provide Executive with the compensation and benefits that had been earned
as of the actual date of Executive’s termination of employment). If the Executive resigns without Good Reason, he will continue
to be paid until his 60-day notice period, or shorter period thereof, ends during the Employment Period. In light of the parties’
understanding and mutual agreement that it is essential that the Corporation have an orderly transition period in the event of
Executive’s resignation without Good Reason, in such event, the Executive agrees to provide any transitional services reasonably
requested by the Board during such notice period (at the Corporation’s sole cost and expense) and further agrees that the
Corporation shall be entitled to obtain equitable relief to the extent needed to require Executive’s specific performance
during the notice period, provided that the Corporation waives any right to seek contractual damages or other monetary remedies
that arise solely with respect to any resignation upon less than sixty (60) days written notice.



This Agreement and the Executive’s
employment hereunder will automatically terminate upon the Executive’s death, without any further obligations on the part
of the Corporation to the Executive or the Executive’s estate, other than accrued and unpaid Basic Salary and accrued and
unused vacation pay, and any other accrued benefit required to be paid by law, up to the date of the Executive’s death.



7.2.Mitigation.
In the event of termination of the Executive’s employment and his execution and non-revocation of the Release and Waiver
that entitles him to severance, the Executive shall have no obligation to find employment.



7.3. Resignation
as Officer or Director. Upon termination of employment, the Executive shall be deemed to automatically resign each position
that he then holds as an officer or director of the Corporation; provided that (and without limiting the foregoing), if requested
by the Corporation, the Executive shall contemporaneously deliver a written notice of resignation to the Board, unless requested
by the Board in writing to continue on in one of his positions with the Corporation.



-6-







7.4. Severance
Benefits For Qualifying Termination. If: (i) the Executive’s employment is terminated either: (A) by the Corporation
without Just Cause (other than due to Executive’s death or Disability), or (B) by the Executive for Good Reason (each a
“Qualifying Termination”); and (ii) the Executive satisfies the Release Requirement, then the Executive will
receive the following Severance Benefits:



7.4.1.          Either
(a) a lump sum cash payment equal to the Executive’s annual Basic Salary at the time of employment termination (without
giving effect to any reduction in Basic Salary that would give Executive the right to resign for Good Reason), less applicable
deductions and withholdings, to be paid by the Corporation on the first payroll period following the Effective Date of the Release
(the “Lump Sum Payment”); or (b) if the Corporation, in the good faith discretion of the Board, is unable to
make the Lump Sum Payment at the time of employment termination due to a lack of sufficient operating funds, an amount equal to
the Executive’s annual Basic Salary (without giving effect to any reduction in Basic Salary that would give Executive the
right to resign for Good Reason) to be paid in substantially equal installments on a monthly basis during the nine (9) month period
following the employment termination date (the “Monthly Installment Payments”); provided that, in each case,
any payments scheduled to be made prior to the Effective Date of the Release shall instead accrue and be paid in a single lump
sum during the first payroll period following the Effective Date of the Release. Notwithstanding the foregoing, the Corporation
may elect to make the Monthly Installment Payments in lieu of the Lump Sum Payment only if an exemption is available from application
of Section 409A of the Code with respect to such payments so that such payment schedule will not result in adverse tax consequences
to Executive under Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations
and other guidance thereunder and any state law of similar effect (collectively “Section 409A”).



7.4.2.          A
lump sum cash payment in an amount equal to the average of the Bonus Remuneration the Executive received from the Corporation
during the last three Years of Employment completed prior to the year of the employment termination, pro rated based on the number
of days the Executive worked during the year of the employment termination divided by 365 (the “Bonus Payment”).
The Bonus Payment, less applicable deductions and withholdings, will be paid on the first payroll period following the Effective
Date of the Release; and



-7-







7.4.3.          If
the Corporation has not previously established a group health plan that Executive has commenced to participate in prior to Executive’s
termination, the Corporation shall continue to pay the Executive a monthly payment of U.S.$2,000.00 (before deduction for income
taxes and other required deductions), payable on the last Friday of each month, for a period of twelve (12) months following the
date of termination, provided that any payments scheduled to be made prior to the Effective Date of the Release shall instead
accrue and be paid during the first payroll period that follows the Effective Date of the Release. If the Corporation has previously
established a group health plan in which Executive participates prior to Executive’s termination and Executive timely elects
COBRA coverage following any Qualifying Termination, the Corporation will pay the Executive for the full amount of such COBRA
premiums for himself and his covered dependants (on a monthly basis) for a period of up to twelve (12) months following the date
of termination; provided, that, if and to the extent that
any benefit described in this Section 7.4.3 is not or cannot be paid or provided under any Corporation plan or program without
adverse tax consequences to the Corporation or for any other reason, as determined by the Corporation in its sole discretion,
then the Corporation shall pay the Executive a fully taxable cash payment equal to the COBRA premium for that month, subject to
applicable tax withholding premiums for a period of up to twelve (12) months following the date of termination; provided,
further, that the COBRA payments or, if applicable, the monthly payment discussed above, shall terminate on the earliest
to occur of (A) the close of the 12-month period following the termination of the Executive’s employment; (B) the expiration
of the Executive’s (or Executive’s dependents’) eligibility for continuation coverage under COBRA; and (C) the
date when the Executive becomes eligible for group health insurance coverage in connection with new employment or self-employment.
If the Executive becomes eligible for coverage under another employer’s group health plan or otherwise ceases to be eligible
for COBRA coverage during the period provided in this Section 7.4.3, Executive must immediately provide written notice to the
Corporation of such event, and the Corporation-provided COBRA payments, or if applicable, the monthly payments under this Section
7.4.3 shall immediately cease.



7.5.Release
Requirement. Notwithstanding the foregoing, to be eligible for any of the Severance Benefits, on or within thirty (30) days
following the termination of employment, the Executive must satisfy the requirement (the “Release Requirement”)
to return to the Corporation a signed and dated general release of all known and unknown claims in a form acceptable to the Corporation
(the “Release and Waiver”) and allow that Release and Waiver to become effective in accordance with its terms
(such date, the “Effective Date of the Release”). No Severance Benefits will be paid hereunder prior to the
Effective Date of the Release. Accordingly, if the Executive breaches the preceding sentence and/or refuses to sign and deliver
to the Corporation an executed Release and Waiver or signs and delivers to the Corporation the Release and Waiver but exercises
his right, if any, under applicable law to revoke the Release and Waiver (or any portion thereof), then the Executive will not
be entitled to any bonus, severance, or payment under this Agreement.



| | 8. | IRS
                                         Code Section 409A
| | -- | --------------------------------------------------------------



Notwithstanding anything to the contrary
herein, the following provisions apply to the extent benefits provided herein are subject to Section 409A. Severance Benefits
shall not commence until the Executive has a “separation from service” for purposes of Section 409A. Each installment
of Severance Benefits is a separate “payment” for purposes of Treas. Reg. Section 1.409A-2(b)(2)(i), and the Severance
Benefits are intended to satisfy the exemptions from application of Section 409A provided under Treasury Regulations Sections
1.409A-1(b)(4), and 1.409A-1(b)(9). However, if such exemptions are
not available and the Executive is, upon separation from service, a “specified employee” for purposes of Section 409A,
then, solely to the extent necessary to avoid adverse personal tax consequences to the Executive under Section 409A, the timing
of the Severance Benefits payments shall be delayed until the earlier of (i) six (6) months and one day after the separation from
service, or (ii) the date of the Executive’s death. If the Corporation determines that any Severance Benefits provided under
this Agreement constitutes “deferred compensation” under Section 409A, for purposes of determining the schedule for
payment of the Severance Benefits the Effective Date of the Release will not be deemed to have occurred any earlier than the sixtieth
(60th) date following the Separation From Service, regardless of when the Release actually becomes effective. The Severance
Benefits are intended to qualify for an exemption from application of Section 409A or comply with its requirements to the extent
necessary to avoid adverse personal tax consequences under Section 409A, and any ambiguities herein shall be interpreted accordingly.

| | 9. | Parachute
                                         Payment
| | -- | ----------------------------------------------------------



If any payment or benefit the Executive
would receive pursuant to this Agreement (“Payment”) would (i) constitute a “Parachute Payment”
within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section
4999 of the Code (the “Excise Tax”), then such Payment shall be reduced to the Reduced Amount. The “Reduced
Amount” shall be either (x) the largest portion of the Payment that would result in no portion of the Payment being
subject to the Excise Tax or (y) the largest portion of the Payment, which such amount, after taking into account all applicable
federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate),
results in the Executive’s receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all
or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting Parachute
Payments is necessary so that the Payment equals the Reduced Amount, reduction shall occur in the following order: reduction of
cash payments; reduction of employee benefits. The accounting firm then engaged by the Corporation for general audit purposes
shall perform the foregoing calculations. The Corporation shall bear all expenses with respect to the determinations by such accounting
firm required to be made hereunder. Any good faith determinations of the accounting firm made hereunder shall be final, binding
and conclusive upon the Executive and the Corporation.

SCHEDULE “B”



EMPLOYEE PROPRIETARY
INFORMATION AND INVENTIONS AGREEMENT



I understand that as part of my employment
(“Employment”) by Lorus Therapeutics Inc. (the “Company”), whether pursuant to that certain
Executive Employment Agreement of even date herewith (the “Employment Agreement”) or otherwise, I am or may
be expected to make new contributions and discoveries of value to the Company. I further understand that my Employment creates
in me a duty of trust and confidentiality to the Company with respect to any information (1) related, applicable or useful to
the business of the Company, including the Company’s anticipated research and development assigned to me by the Company;
or (2) resulting from the use of equipment, supplies or facilities owned, leased or contracted for by the Company; or (3) related,
applicable or useful to the business of any client of the Company, which may be made known to me by the Company or by any client
of the Company, or learned by me during the period of my Employment.



As part of the consideration for my Employment
and the compensation received by me from the Company (including bonuses and benefits) from time to time, I hereby agree as follows:



1.          All
Proprietary Information (as defined on Annex 1 hereto) and Inventions (as defined on Annex 1 hereto) shall be the
sole property of the Company and its assigns, and the Company and its assigns shall be the sole owner of all patents, trademarks,
service marks and copyrights and other rights (collectively referred to herein as “Rights”) pertaining to Proprietary
Information and Inventions. I hereby assign to the Company any rights I may have or acquire in Proprietary Information or Inventions
or Rights pertaining to the Proprietary Information or Inventions. I further agree as to all Proprietary Information or Inventions
to assist the Company or any person designed by it in every proper way (but at the Company’s expense) to obtain and from
time to time enforce Rights relating to said Proprietary Information or Inventions in any and all countries. I will execute all
documents for use in applying for, obtaining and enforcing such Rights on such Proprietary Information or Inventions as thereof
to the Company or persons designated by it. My obligation to assist the Company or any person designated by it in obtaining and
enforcing Rights relating to Proprietary Information or Inventions shall continue beyond the cessation of my Employment (“Cessation
of my Employment”), but the Company shall compensate me at a reasonable rate after the Cessation of my Employment for
time actually spent by me upon the Company’s request for such assistance. In the event the Company is unable, after reasonable
effort, to secure my signature on any document or documents needed to apply for or enforce any Right relating to Proprietary Information
or to an Invention, whether because of my physical or mental incapacity or for any other reason whatsoever, I hereby irrevocably
designate and appoint the Company and its duly authorized officers and agents as my agents and attomeys-in-fact to act for and
in my behalf and stead in the execution and filing of any such application and in furthering the application for an enforcement
of Rights with the same legal force and effect as if such acts were performed by me. I hereby acknowledge that all original works
of authorship which are made by me (solely or jointly with others) within the scope of my Employment and which are protectable
by copyright are “works for hire” as that term is defined in the United States Copyright Act (17 USCA, Section 101).











2.          I
will promptly disclose to the Company, and the Company hereby agrees to receive such disclosures in confidence, all discoveries,
developments, designs, improvements, inventions, formulas, software programs, processes, techniques, know-how, negative know-how
and data, whether or not patentable or registrable under patent, copyright or similar statutes or reduced to practice, made or
conceived or reduced to practice or learned by me, either alone or jointly with others during the period of my Employment, for
the purpose of permitting the Company to determine whether they constitute Inventions. In order to facilitate the complete and
accurate disclosures described above, I agree to maintain complete written records of all Inventions, and of all work, study and
investigation related thereto done by me during my Employment, which records shall be the property of the Company.



3.          At
all times, both during my Employment and after the Cessation of my Employment, whether the cessation is voluntary or involuntary,
for any reason or no reason, or by disability, I will keep in strictest confidence and trust all Proprietary Information, and
I will not disclose, use, or induce or assist in the use or disclosure of any Proprietary Information or Rights pertaining to
Proprietary Information, or anything related thereto, without the prior express written consent of the Company, except as may
be necessary in the ordinary course of performing my duties as an employee of the Company. I recognize that the Company has received
and in the future will receive from third parties their confidential or proprietary information subject to a duty of the Company’s
part to maintain the confidentiality of such information and to use it only for certain limited purposes. I agree that I owe the
Company and such third parties, during my Employment and thereafter, a duty to hold all such confidential or proprietary information
in the strictest confidence, and I will not disclose, use, or induce or assist in the use or disclosure of any such confidential
or proprietary information without the prior express written consent of the Company, except as may be necessary in the ordinary
course of performing my duties as an employee of the Company consistent with the Company’s agreement with such third party.



4.          I
acknowledge that during my Employment with the Company, I have a fiduciary duty and/or duty of loyalty to the Company. During
the period of my Employment, I will not, unless provided for in my Employment Agreement or with the Company’s express written
consent: (a) directly or indirectly engage in any activity which is in competition with the Company, (b) alone or in concert with
others, in any way use or disclose Proprietary Information in order to solicit, entice or in any way divert any client to do business
with any business entity in competition with the Company, or (c) make any copies of Proprietary Information without the express
written authorization of the Company, unless such copies are necessary in the ordinary course of performing my duties as an employee
of the Company. Additionally, I agree that during my Employment with the Company and for one (1) year thereafter, I will not either
directly or indirectly, solicit or attempt to solicit any employee, independent contractor, or consultant of the Company to terminate
his, her or its relationship with the Company in order to become an employee, consultant, or independent contractor to or for
any other person or entity.



5.          In
the event of the Cessation of my Employment, I will deliver to the Company all devices, records, sketches, reports, proposals,
client information, lists, correspondence, equipment, software, documents, photographs, photostats, negatives, undeveloped film,
notes, drawings, specifications, tape recordings or other electronic recordings, programs, data and other materials or property
of any nature belonging to the Company or pertaining to my work with the Company, and I will not take with me, or allow a third
party to take, any of the foregoing or any reproduction of any of the foregoing.











6.          Any
provision in this Agreement requiring me to assign my rights in any invention shall not apply to an invention that qualifies fully
under the provisions of Section 2870 of the California Labor Code, the terms of which have been set forth on Annex 1 to
this Agreement. I understand that I bear the full burden of proving to the Company that an invention qualifies fully under Section
2870. By signing this Agreement, I acknowledge receipt of a copy of this Agreement and of written notification of the provisions
of Section 2870. Notwithstanding the foregoing, I also assign to the Company (or as directed by it) any rights I may have or acquire
in any Invention, full title to which is required to be in the United States by a contract between the Company and the United
States or any of its agencies.



7.          As
a matter of record I have listed in Item 1 of Annex 2 attached hereto all inventions or improvements relevant to the
subject matter of my Employment which have been made or conceived of or first reduced to practice by me alone or jointly with
others prior to my Employment. I represent and warrant that such list is complete. I further represent and warrant that, in
due consideration for my Employment and the compensation received by me from the Company, and in return for the Company
reimbursing me for the fees associated with the patent application described under Annex 2, I hereby voluntarily agree
to sell, convey, assign and transfer unto the Company, its successors, assigns and legal representatives, the full and
exclusive right, title and interest in and to the patent application described under Annex 2, for which I am the sole
inventor, and all related U.S. and foreign patent applications and patents. I hereby covenant that I have the full right to
convey the patent application and all related U.S. and foreign patent applications and patents, and that I have not executed
and will not execute any agreement in conflict herewith. I hereby agree and acknowledge that California Labor Code Section
2870 does not apply to my voluntary assignment of the patent application described under Annex 2.



8.          I
represent that my performance of all the terms of this Agreement and as an employee of the Company does not and will not breach
any agreement to keep in confidence proprietary information acquired by me in confidence or in trust prior to my Employment with
the Company. I have not entered into, and I agree that I will not enter into, any agreement, either written or oral, in conflict
herewith.



9.          I
represent and warrant to and covenant with the Company that I will not bring to the Company, as of this date, any materials or
documents of a former employer (which term, for purposes of this paragraph 9, shall also include persons, firms, corporations
and other entities for which I have acted as an independent contractor or consultant) that are not generally available to the
public, unless I have obtained written authorization from any such former employer for their possession and use. The materials
or documents of a former employer that are not generally available to the public that I will bring to the Company for use in my
Employment are identified in Item 2 of Annex 2 attached hereto, and as to each such item, I represent and warrant that
I have obtained prior to the commencement date of my Employment express written authorization for their possession and use in
my service to the Company. I also understand that, in my service to the Company, I am not to breach any obligation of confidentiality
that I have to former employers, and I agree to fulfill all such obligations during my Employment.











10.          I
acknowledge that irreparable injury will result to the Company from my violation or continued violation of the terms of this Agreement,
and I expressly agree that the Company shall be entitled, in addition to damages and any other remedies provided by law, to an
injunction or other equitable remedy respecting such violation or continued violation by me.



11.         The
terms and conditions of this Agreement shall apply to any period, if any, during which I perform services for the Company as a
consultant or independent contractor, as well as any time during which I am employed directly by the Company. Upon the Cessation
of my Employment, I agree to sign and deliver the “Termination Certificate” attached hereto as Annex 3.
My failure to sign such Termination Certificate, however, shall not affect my obligations under the Agreement.



12.         Nothing
in this Agreement shall obligate the Company to continue to retain me as an employee. I understand that this means that the Company
has and will continue to have the absolute and unconditional right to terminate my Employment for any reason or no reason, with
or without cause or prior notice, provided that such termination shall not relieve the Company of any obligations it may have
to make payments to me pursuant to the Employment Agreement.



13.         I
acknowledge that I have carefully read this Agreement, know its contents, and either have been represented by independent counsel
who has explained to me the legal consequences of this Agreement or have determined not to obtain such independent counsel after
being advised by the Company to obtain such independent counsel.

Annex 1 to Schedule

“PROPRIETARY
INFORMATION” DEFINED:



For purposes of this Agreement, “Proprietary
Information”shall mean information not generally available to the public that has been created, discovered,
developed, or otherwise become known to the Company or in which property rights have been assigned or otherwise conveyed to the
Company, which information has material economic value or potential material economic value to the business in which the Company
is or will be engaged. Proprietary Information shall include, but not be limited to (i) trade secrets, processes, formulas, data,
know-how, negative know-how, improvements, discoveries, developments, designs, inventions, techniques, all technical data, proposals,
reports, and client information compiled by the Company, and any modifications or enhancements thereto, software, programs, and
information (whether or not necessarily in writing) which has actual or potential economic value to the Company, (ii) all loan
prospects and applications in process or pipeline that are generated or produced at any time during the term of this Agreement,
and (iii) the operating, investment, pricing or similar or other policies, procedures, practices or systems of the Company.



“INVENTIONS”
DEFINED:



For purposes of this Agreement, “Inventions”shall mean all discoveries, developments, designs, improvements, inventions, formulas, software, programs, processes,
techniques, know-how, negative know-how, and data, whether or not patentable or registrable under patent, copyright or similar
statutes, that are related to or useful in the business or future business of the Company or result from use of premises or other
property owned, leased or contracted for by the Company. Without limiting the generality of the foregoing, Inventions shall also
include anything that derives actual or potential economic value from not being generally known to the public, or to other persons
who can obtain economic value from its disclosure or use, in each case that are related to or useful in the business or future
business of the Company.



CALIFORNIA LABOR CODE
SECTION 2870:



(a)  Any
provision in an employment agreement which provides that an employee shall assign, or offer to assign, any of his or her rights
in an invention to his or her employer shall not apply to an invention that the employee developed entirely on his or her own
time without using the employer’s equipment, supplies, facilities, or trade secret information except for those inventions
that either:



(1)  Relate
at the time of conception or reduction to practice of the invention to the employer’s business, or actual or demonstrably
anticipated research or development of the employer.



(2)  Result
from any work performed by the employee for the employer.











(b)  To
the extent a provision in an employment agreement purports to require an employee to assign an invention otherwise excluded from
being required to be assigned under subdivision (a), the provision is against the public policy of this state and is unenforceable.
