                                         Conflicting Obligations
| | -- | -------------------------------------------------------------------



| | 9.1. | The Executive warrants to the Corporation that:
| | ---- | -----------------------------------------------



| | 9.1.1. | the performance of the Executive’s duties as an employee of the Corporation will not breach
any agreement or other obligation to keep confidential the proprietary information of any third party; and
| | ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 9.1.2. | the Executive is not bound by any agreement with or obligation to any third party that conflicts with
the Executive’s obligations as an employee of the Corporation or that may affect the Corporation’s interest in the
Developments.
| | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 9.2. | The Executive will not, in the performance of the Executive’s
duties as an employee of the Corporation:
| | ---- | -------------------------------------------------------------------------------------------------------

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



| | 10. | Confidential
                                         Information
| | --- | -----------------------------------------------------------------



The
Executive agrees that the Confidentiality Agreement executed by the Executive on October 29, 1999 remains in full force and effective
following the effective date of this Agreement and forms part of this Agreement.



| | 11. | Competition
                                         and Solicitation
| | --- | ---------------------------------------------------------------------



11.1.	       Non-Competition.
The Executive acknowledges that employment by the Corporation will give the Executive access to the Confidential Information, and
that the Executive’s knowledge of the Confidential Information will enable the Executive to put the Corporation at a significant
competitive disadvantage if the Executive is employed or engaged by or becomes involved in a Competitive Business. Accordingly,
during the Employment Period and for the relevant period of time specified in Schedule “A” after the Termination Date,
the Executive will not, directly or indirectly, individually or in partnership or in conjunction with any other Person:



| | 11.1.1. | be engaged, directly or indirectly, in any manner whatsoever, including, without limitation, either
individually or in partnership, jointly or in conjunction with any other person, or as an employee, consultant, adviser, principal,
agent, member, shareholder or proprietor in any Competitive Business; or
| | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------





- 14 -







| | 11.1.2. | advise, invest in, lend money to, guarantee the debts
or obligations of, or otherwise have any other financial or other interest (including an interest by way of royalty or other compensation
arrangements) in or in respect of any Person which carries on a Competitive Business.
| | ------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



The
restrictions in section 11.1 above will not prohibit the Executive from (i) holding not more than five percent of the issued shares
of a public company listed on any recognized stock exchange or traded on any bona
fide “over the counter” market anywhere in the world or (ii) with the prior written consent of the board
of directors of the Corporation, which consent will not be unreasonably withheld, serve on the board of directors of other corporations
or accept part-time unpaid academic appointments, provided that any such board or academic appointment does not interfere with
the performance of the Executive’s obligations hereunder, is not a Competitive Business and provides, in a manner satisfactory
to the board of directors of the Corporation, for the adequate protection of any intellectual property arising out of or in connection
with such appointment.



For
greater certainty, the Executive’s obligations under this section 11.1 are in addition to the obligations respecting disclosure
and use of Confidential Information pursuant to the Confidentiality Agreement referred to in section 10.



11.2.   No
Solicitation of Clients and Suppliers. The Executive acknowledges the importance to the business carried on by the Lorus
Group of the client and supplier relationships developed by it and the unique opportunity that the Executive’s employment
and the Executive’s access to the Confidential Information offers to interfere with these relationships. Accordingly, the
Executive will not while employed or engaged by the Lorus Group and for the period of time specified in Schedule “A”,
directly or indirectly, contact or solicit any person who the Executive knows to be a prospective, current or former client or
supplier of the Lorus Group for the purpose of selling to the client or buying from the supplier any products or services that
are the same as or substantially similar to, or in any way competitive with, the products or services sold or purchased by the
Lorus Group during the Executive’s Employment or at the end thereof, as the case may be.



11.3.	   No
Solicitation of Employees. The Executive acknowledges the importance to the business carried on by the Lorus Group of
the human resources engaged and developed by it and the unique access that the Executive’s employment offers to interfere
with these resources. Accordingly, the Executive will not during the Employment Period and for the period of time specified in
Schedule “A”, induce or solicit, attempt to induce or solicit or assist any third party in inducing or soliciting any
employee or consultant of the Lorus Group, to leave the Lorus Group or to accept employment or engagement elsewhere.



11.4.   Independent
Covenants. Each of sections 11.1, 11.2 and 11.3 will be construed as constituting obligations independent of any other
obligations in this Agreement. The existence of any claim or cause of action the Executive may have or assert against the Corporation,
whether based on this Agreement or otherwise, will not constitute a defence to the enforcement by the Corporation of any of the
covenants and agreements in the foregoing sections.





- 15 -







| | 12. | Intellectual
Property Rights
| | --- | ----------------------------



12.1.       Ownership.
All Developments will be the exclusive property of the Lorus Group and the Lorus Group will have sole discretion to deal with Developments.
For greater certainty, all work done during the Employment Period by the Executive for the Corporation or a member of the Lorus
Group is a work for hire of which the Corporation or the member of the Lorus Group, as the case may be, is the first author for
copyright purposes and in respect of which all copyright will vest in the Corporation or the relevant member of the Lorus Group,
as the case may be.



12.2.        Records.
The Executive will keep complete, accurate and authentic notes, reference materials, data and records of all Developments in the
manner and form requested by the Corporation. All these materials will be Confidential Information upon their creation.



12.3.        Moral
Rights. The Executive hereby irrevocably waives all moral rights arising under the Copyright
Act (Canada) as amended (or any successor legislation of similar effect) or similar legislation in any applicable jurisdiction,
or at common law, that the Executive may have now or in the future with respect to the Developments, including, without limitation,
any rights the Executive may have to have the Executive’s name associated with the Developments or to have the Executive’s
name not associated with the Developments, any rights the Executive may have to prevent the alteration, translation or destruction
of the Developments, and any rights the Executive may have to control the use of the Developments in association with any product,
service, cause or institution. The Executive agrees that this waiver may be invoked by the Corporation, and by any of its authorized
agents or assignees, in respect of any or all of the Developments.



12.4.        Further
Assurances. The Executive will do all further things that may be reasonably necessary or desirable in order to give
full effect to the foregoing. If the Executive’s co-operation is required in order for the Lorus Group to obtain or enforce
legal protection of the Developments following the termination of the Executive’s employment, the Executive will provide
that co-operation so long as the Corporation pays to the Executive reasonable compensation for the Executive’s time at a
rate to be agreed, provided that the rate will not be less than the last basic salary or compensation rate paid to the Executive
by the Corporation during the Executive’s employment.



| | 13. | Warranties.
Covenants and Remedies
| | --- | ----------------------------------



13.1.       The
obligations of the Executive as set forth in sections 9, 10, 11 and 12 of this Agreement will be deemed to have commenced as of
the date on which the Executive was first employed by the Lorus Group. The Executive warrants that the Executive has not, to date,
breached any of the obligations set forth in any of those sections. Any breach or threatened breach of those sections by the Executive
will constitute Just Cause for immediate termination of the Executive’s employment or engagement by the Corporation.



- 16 -







13.2.       The
Executive understands that the Lorus Group has expended significant financial resources in developing its products and the Confidential
Information. Accordingly, a breach or threatened breach by the Executive of any of sections 9, 10, 11, 12 or 13.1 could result
in unfair competition with the Lorus Group and could result in the Lorus Group and its shareholders suffering irreparable harm
that is not capable of being calculated and that cannot be fully or adequately compensated by the recovery of damages alone. Accordingly,
the Executive agrees that the Corporation will be entitled to interim and permanent injunctive relief, specific performance and
other equitable remedies, in addition to any other relief to which the Corporation or the Lorus Group may become entitled.



13.3.       The
Executive’s obligations under each of sections 9,10,11,12,13.1 and 13.2 are to remain in effect in accordance with each of
their terms and will exist and continue in full force and effect despite any termination, breach or repudiation, or alleged breach
or repudiation, of this Agreement or the Executive’s employment (including, without limitation, the Executive’s wrongful
dismissal) by the Corporation or the Lorus Group.



| | 14. | Co-operation
by Executive
| | --- | -------------------------



The
Executive will co-operate in all respects with the Corporation if a question arises as to whether the Executive has a Disability.
Without limitation, the Executive will authorize the Executive’s medical doctor or other health care specialist to discuss
the condition of the Executive with the Corporation and will as reasonably requested by the Corporation submit to examination by
a medical doctor or other health care specialist selected by the Corporation.



| | 15. | Employers
and Employees Act Not to Apply
| | --- | ----------------------------------------



The
Corporation and the Executive agree that section 2 of the Employers
and Employees Act (Ontario) or other similar provisions in Applicable Employment Legislation will not apply to or in
respect of this Agreement or the employment of the Executive hereunder.

notice or other communication required or permitted to be given hereunder must be in writing, and must be given by facsimile or
other means of electronic communication or by hand-delivery as hereinafter provided, except that any notice of termination by the
Corporation under section 8 above must be hand-delivered or given by registered mail. Any notice or other communication, if mailed
by registered mail, will be deemed to have been received on the day that mail is delivered by the post office, or if sent by facsimile,
will be deemed to have been received on the Business Day following the sending, or if delivered by hand to the Executive will be
deemed to have been received at the time it is delivered to the Executive or, if delivered to the Executive or the Corporation
at the applicable address noted in Schedule “A”, when it is delivered either to the individual designated in Schedule
“A” or to an individual at that address having apparent authority to accept deliveries on behalf of the addressee.
Notice of change of address will also be governed by this section. Notices and other communications must be addressed as set out
in Schedule “A”.



| | 17. | Headings
| | --- | --------



The
inclusion of headings in this Agreement is for convenience of reference only and is not to affect construction or interpretation.



- 17 -







| | 18. | Invalidity
of Provisions
| | --- | ------------------------



Each
of the provisions contained in this Agreement is distinct and severable and a declaration of invalidity or unenforceability of
any provision by a court of competent jurisdiction will not affect the validity or enforceability of any other provision.

Agreement, the attached Schedule “A” and the Confidentiality Agreement referred to in section 10 constitute the entire
agreement between the parties pertaining to the subject matter of this Agreement. This Agreement supersedes and replaces all prior

prior employment, if any, by the Lorus Group. There are no warranties, representations or agreements between the parties in connection

reduced to writing and included as a term of this Agreement. Accordingly, there will be no liability, either in tort or in contract,
assessed in relation to any representation, opinion, advice or assertion of fact, except to the extent aforesaid.



| | 20. | Waiver,
Amendment
| | --- | -----------------



Except
as expressly provided in this Agreement, no amendment or waiver of this Agreement will be binding unless executed in writing by
the party to be bound. No waiver of any provision of this Agreement will constitute a waiver of any other provision nor will any
