|2.4 | The grant of licenses by Zentaris to AOI under
Section 2.1 hereof shall not preclude Zentaris itself from utilizing Zentaris' Patent Rights and Zentaris' Know-How and any
Improvements relating thereto for the purpose of carrying out by itself or through a University, a contract research organization
or a non-profit organization (provided that a material transfer agreement is in place to protect any intellectual property rights
generated) any further non-commercial exploratory and development work relating to Perifosine.  If
Zentaris engages a University, contract research organization or other non-profit organization to undertake such further
exploratory or development work, Zentaris shall inform AOI of the nature of such engagement, including but not limited to providing
brief details of the exploratory or development work to be conducted, and the name of the relevant University, contract research
organization or other non-profit organization.

|2.5 | In furtherance of the rights and licenses granted
by Zentaris to AOI under this Agreement, within thirty (30) days after the Effective Date of this Agreement, Zentaris shall furnish
to AOI a data package that shall include all of Zentaris’ Know-How. AOI shall not use any of Zentaris' Know-How furnished by
Zentaris under this Section 2.5 for any purpose whatsoever, except as specifically authorized in this Agreement, or as otherwise
specifically authorized in writing by Zentaris. In the event that AOI reasonably believes that Zentaris' Know-How included in the
data package furnished by Zentaris under this Section 2.5 is incomplete, AOI shall provide written notice thereof to Zentaris, and
Zentaris shall furnish corrected copies of Zentaris' Know-How within 30 days after receipt of AOI's written notice hereunder. 
Zentaris shall use its reasonable endeavors to answer all questions received from AOI regarding Zentaris' Know-How as soon as
reasonably possible after receipt. However, if Zentaris foresees that specific questions of AOI will invoke significant costs and
expenses for Zentaris, Zentaris shall provide AOI with an estimate of such costs and expenses.  In such event, Zentaris shall
only be obliged to assist AOI if AOI agrees to refund Zentaris any costs and expenses incurred in providing such
assistance.
|2.6 | Zentaris shall execute all documents and give all
declarations regarding the licenses granted hereunder and reasonably cooperate with AOI at the costs of AOI to the extent such
documents, declarations and/or cooperation are required for the recordal or registration of the licenses granted hereunder at the
various patent offices in the Territory for the benefit of AOI.

subject to any mandatory legal provisions which may apply, AOI shall not knowingly develop, manufacture, sell, use, offer for sale
or import any of the Contract Products or Perifosine for any other application or purpose whatsoever, and shall not actively
promote, or solicit orders for the sale of the Contract Products outside of the Territory, without the prior written authorization

order to maximize the Net Sales derived from such Contract Products throughout the continuance of this Agreement, provided,
however, that AOI shall terminate this Agreement in accordance with Section 15.2 if it determines that it will not be commercially

there is generic competition to the Contract Product.  AOI shall be deemed to meet its reasonable best efforts obligation, if
it adheres to the development plan, as attached hereto in Exhibit 5.1 or to an amended development plan, provided the amendment was
agreed upon by the Co-ordination Committee or the CEOs of the Parties in accordance with Section 5.4. Without limiting the

|3.3 | After the First Commercial Sale in the Territory, AOI shall furnish Zentaris with quarterly reports of all of AOI's sales of Contract Products under this Agreement. Each such

forty-five (45) days after the close of the calendar quarter to which it corresponds; and (ii) state AOI's total sales of the
Contract Products, broken down by country, during the calendar quarter, the Net Sales derived by AOI from such sales, and the
royalties payable by AOI to Zentaris with respect to such Net Sales pursuant to Section 4.4 of this Agreement. In addition,
commencing on April 1 in the calendar year following the date of the First Commercial Sale in the Territory, AOI shall provide
Zentaris on or before April 1 in each calendar year with a brief summary of its marketing activities performed in the Territory in
the previous calendar year and its marketing plans for that calendar year.

|4.5 | In the event
that Contract Product is sold in the form of a combination product containing one or more products or technologies which are
themselves not Perifosine, the Net Sales for such combination product shall be calculated by multiplying the sales price of such
combination product by the fraction A/(A+B) where A is the invoice price of Perifosine or the fair market price of Perifosine if
sold to an Affiliate and B is the total invoice price of the other products or technologies or the fair market price of the other
products or technologies if purchased from an Affiliate. If A and B cannot be reasonably calculated (e.g., if there is not a market
for either or both of the components of the combination product), then the Co-ordination Committee will meet to agree on the
relative portion of the value of the combination product that is represented by each component. If the Co-ordination Committee
cannot agree within ninety (90) days of the First Commercial Sale on the relative proportion attributable to each, then the matter
will be referred to a face-to-face meeting of the CEO's of each of the Parties. If the CEO's are unable to reach an agreement
within ninety (90) days, the matter will be subject to arbitration pursuant to Section 16.5.
|4.6 | Royalty payments shall be made on a country by
country and a Contract Product by Contract Product basis for the lifetime a Valid Claim of any of the Zentaris' Patent Rights
falling under Section 1.24 (a) above or for a period of ten (10) years from the date of First Commercial Sale in the respective
country, whichever term is longer. In countries in which the Contract Product is not covered by a Valid Claim of Zentaris' Patent
Rights, AOI shall only pay [*****] percent ([**]%) of the applicable royalty set forth above for any Net Sales of such Contract
Product, provided, however, if such Contract Product is sold in a generic form in such country by a party other than AOI, its
Affiliates or sublicensees, and such generic form has a market share of more than [***********]  percent ([**]%), then AOI shall not pay any royalties on Net
Sales for such Contract Product.

|4.7  | All payments by AOI to Zentaris under this
Agreement shall be paid in US Dollars. In the event that any Net Sales received by AOI are received in any currency other than US
Dollars, for purposes of calculating the royalties payable by AOI under Section 4.4 hereof, such Net Sales shall be converted into
US Dollars at the prevailing open market currency conversion rate (commercial selling rate) as quoted by the Wall Street Journal
fixing rate, issued by Reuters at 3 pm on the last day of the calendar quarter in which such Net Sales were received by
AOI.

over the prime rate as quoted by Citibank NA.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
|4.10 | All payments by AOI to Zentaris under this Section 4 shall be
paid in full, without deduction for any sales, use, excise, withholding or other similar taxes. All payments are exclusive of value
added tax, which shall if applicable, be invoiced separately. Notwithstanding the foregoing, in the event that AOI is required to
withhold any taxes on any amount payable to Zentaris hereunder, under the applicable laws of any country within the Territory, AOI
shall at Zentaris' request and cost use its best efforts to obtain and furnish Zentaris with official tax receipts, or other
evidence of payment of such withholding taxes, sufficient to permit Zentaris to demonstrate the payment of such withholding taxes,
in order to establish Zentaris' right to a credit for such withholding taxes against Zentaris' German income tax liability. AOI
shall provide Zentaris with all assistance reasonably requested by Zentaris in connection with any application to any competent tax
authorities in any country within the Territory to qualify for the benefit of a reduced rate of withholding taxation under any
applicable Double Tax Treaty.                                                                                                                                                                                                                                                                                                                                                                                                                                                   
|4.11 | AOI shall maintain for a period of five (5) years complete
and accurate books and records of account, in accordance with generally accepted accounting principles, of all transactions and
other business activities under this Agreement, sufficient to confirm the accuracy of all reports furnished by AOI to Zentaris
under Section 3.3 hereof, and all payments by AOI to Zentaris under this Section 4. Upon reasonable written notice of no less than
30 days to AOI but in no event more than once per year, Zentaris or a certified public accountant designated by Zentaris and
reasonably acceptable to AOI shall have the right to audit such books and records of account of AOI and to review the terms of any
sublicenses granted by AOI (provided always that in the case of review by a certified public accountant, the relevant public
accountant enters into an appropriate confidentiality agreement with AOI), in order to confirm the accuracy and completeness of all
such reports and all such payments. Zentaris shall bear all costs and expenses incurred in connection with any such audit;
provided, however, that if any such audit reveals a variance of the greater of [***]percent ([*]%) or [*********** *********]US Dollars (US$ [******]) between the amount of payments actually due and the amount of payments
made to Zentaris in any calendar quarter, then, in addition to paying the full amount of such underpayment, plus accrued interest
in accordance with Section 4.9 hereof, AOI shall reimburse Zentaris for all such external costs and expenses reasonably
incurred.

|5.1 | A draft development plan is attached hereto as
Exhibit 5.1. AOI shall be responsible for conducting all necessary research and development activities in order to obtain
the necessary Regulatory Approvals for the Contract Products in the Territory and to maximize the commercial potential of the
Contract Products. AOI shall be solely responsible for all costs and expenses incurred by AOI in conducting, or otherwise in
connection with, such research and development, including but not limited to the costs of clinical supply for the NCI Phase II
studies. As soon as possible, following the Effective Date, Zentaris shall use its best efforts to obtain from the NCI a written
letter granting AOI permission to cross-reference the IND owned by the NCI.  Additionally, Zentaris shall permit AOI to access
the documentation of the manufacturing process (equivalent to a Drug Master File) for Perifosine for AOI’s IND filing and for
the filing of the NDA if Zentaris is AOI’s primary manufacturer.
|5.2 | The Parties shall form a Co-ordination Committee, which shall be comprised
    of up to four (4) professionally and technically qualified representatives,
    two (2) from each Party. Each Party shall provide the other Party with
    written notice of its representatives for the Co-ordination Committee within
    ten (10) days after the Effective Date of this Agreement and, thereafter,
    immediately upon replacement. The Co-ordination Committee shall meet twice a
    year and more often upon request of either Party. The meeting places shall
    alternate between the offices of the Parties in Frankfurt and New York,
    provided, that any meeting requested by a Party in addition to the biannual
    meetings shall be held at the place of the other Party.                                                                                                                                                                                                                                     
|5.3 | The Parties shall form a Co-ordination Committee, which shall be comprised
    of up to four (4) professionally and technically qualified representatives,
    two (2) from each Party. Each Party shall provide the other Party with
    written notice of its representatives for the Co-ordination Committee within
    ten (10) days after the Effective Date of this Agreement and, thereafter,
    immediately upon replacement. The Co-ordination Committee shall meet twice a
    year and more often upon request of either Party. The meeting places shall

|5.4 | All decisions of the Co-ordination Committee
regarding the development plan shall be made in good faith in the best interest of this Agreement and shall be unanimous. In the
event that the Co-ordination Committee is unable to agree upon an amendment of the development plan requested by AOI after good
faith attempts to resolve such disagreement in a commercially reasonable fashion, then either Party may refer the disagreement to a
personal face-to-face meeting between the Chief Executive Officer of Zentaris and the Chief Executive Officer of AOI which meeting
shall take place within fourteen (14) days of the date of the relevant referral. If the Chief Executive Officer of Zentaris and the
Chief Executive Officer of AOI cannot resolve such disagreement in a mutually acceptable manner within a further fourteen (14) days
after such personal face-to-face meeting, then AOI shall have the casting vote.

|5.5 | An additional goal of the Co-ordination Committee
shall be to coordinate clinical and pre-clinical studies that are being conducted by each of the Parties in the Territory, with
respect to AOI, and outside of the Territory, with respect to Zentaris, to minimize duplication of efforts and studies and to
maximize combined resources to obtain Development Data that is useful for each of the Parties.  Accordingly, each Party shall
provide the Co-ordination Committee with written notice of all pre-clinical and clinical studies, including any known investigator
initiated trials, together with the results thereof, of the use of the Contract Products and/or Perifosine in the Field, conducted
by that Party during the continuance of this Agreement. Each Party shall make available to the other Party, and to the members of
the Co-ordination Committee, copies of all Development Data prepared by or for that Party during the continuance of this Agreement.
All Development Data furnished by one Party to the other Party under this Agreement shall be deemed Confidential Information of the
Party furnishing such results, studies, scientific information, know-how or other data.

|6.1 | Subject only to Section 6.2
      below, each Party will disclose to the other Party all Development Data, which it generates or which is generated by its licensees
      during the period of this Agreement, and each Party shall be entitled to disclose such Development Data to its licensees. The Parties
      shall ensure that its licensees agree to the disclosure of their Development Data to the other Party and its licensees and keep
      confidential all Development Data disclosed to them pursuant to this Section 6.1 except for the use of Development Data for Regulatory
      Filings. Each Party and their licensees shall be entitled to use the Development Data disclosed pursuant to this Section 6.1 for
      the development and commercialization of Perifosine and/or Contract Product in accordance with the terms of this Agreement [****
      ** *******].                                                                                                                                                                                                                                                                                                                 
|6.2 | Certain Development Data, which were developed by
licensees of Zentaris and specified in Exhibit 6.2 hereto, may only be used by AOI and/or its licensees for NDA submission
upon written request of AOI to Zentaris and against payment of a license fee, the amount of which shall be agreed between the
Parties; provided, however, that prior to or outside of an NDA submission, AOI shall be permitted to use such data for any other
purpose free of charge (including, without limitation, for an IND submission).

to Zentaris, if possible, sixty (60) days, but in any event not less than thirty (30) days, written notice before any relevant
deadline relating to or any public disclosure of such patent application or patent outside of the Territory.  Upon receipt of
a notice from AOI indicating that it intends to cease prosecuting or maintaining any such patent right, Zentaris shall have the
right to continue, at its own expense, prosecution or maintenance (as the case may be) of such patent right outside of the
Territory, and AOI shall at the request and cost of Zentaris do all such acts and execute all such documents as may be necessary to
assist Zentaris with the prosecution and maintenance of the patent rights.

|7.7 | Immediately after the execution of this Agreement, Zentaris shall execute such instruments and shall use its best efforts to obtain appropriate agreements with the NCI to effect an
assignment of the CRADA with any of its rights and obligations to AOI and to permit the cross-referencing of the NCI’s IND
for Perifosine. If the NCI does not approve the assignment of the CRADA, Zentaris shall put AOI commercially in the same position,
as AOI would be in if the CRADA had been effectively assigned.  After an assignment of the CRADA to AOI, AOI shall be obliged
to file any patents it is entitled to under the CRADA as well as to exercise any license options granted under the CRADA. 
With respect to any of such patents and licenses, AOI shall, and hereby does, grant Zentaris an exclusive, perpetual, royalty-free
license to use such patents outside the Field and/or outside the Territory for any purpose whatsoever provided that Zentaris shall
reimburse AOI for any patent expenses incurred which are related to such patent applications outside the Field and/or outside the
Territory.

8.2 but for a period of not less than twelve (12) months following the Effective Date, AOI shall purchase all  Perifosine bulk
substance and/or finished dosage form (tablets) (collectively referred to as the “Clinical Supplies”), whichever is
specified in the applicable purchase order described below, required for development of Perifosine and
Contract Products exclusively from Zentaris and Zentaris shall sell such Clinical Supplies to AOI in order to be able to ensure
conformity of development results with other licensees of Zentaris for Perifosine.  The sources from which Zentaris purchases
Clinical Supplies   for resale to its licensees as of the Effective Date are listed in Exhibit
8.1A. Exhibit 8.1B hereto sets forth the specification for the Clinical Supplies (to be determined
within a reasonable time after execution of the Agreement) to be delivered to AOI, and any change of such
specifications shall be agreed between the Parties, acting reasonably.  During the term of supply, AOI shall at the beginning
of each quarter present to Zentaris a rolling forecast specifying its estimated demand of Clinical Supplies and specifying, if
applicable, between bulk substance or finished dosage form (tablets) forecasted to be purchased for the following twelve (12)
months. Unless otherwise agreed, upon receipt of approved AOI purchase order for Perifosine bulk substance and in finished dosage
form (tablets), Zentaris will deliver to such address as may be specified by AOI no later than three (3) months for the bulk
substance and will make best efforts to deliver finished dosage form (tablets) within six (6) months. The purchase price to be paid
by AOI for materials purchased from Zentaris shall be the price paid by Zentaris for production and
laboratory services plus a handling and managing charge.  This charge shall be [**]% if AOI requests supply of Perifosine bulk substance, and [**]% if AOI requests finished dosage form (tablets).

|8.2 | Following the first anniversary of this Agreement,
if AOI decides to purchase Clinical Supplies from a source other than Zentaris, AOI shall pay to Zentaris any reasonable quality
assurance and/or quality control costs necessary to confirm conformation of the Perifosine bulk substance acquired from the second
source with the specifications set forth in Exhibit 8.1B hereto.

|8.3 | The supply of Perifosine bulk substance for
commercial production of Contract Products and the supply of a finished dosage form of Perifosine and Contract Product by Zentaris
to AOI is subject to a separate agreement between the Parties, provided that in the event AOI determines in its sole discretion
that it is prudent to arrange an alternative or secondary supplier of Perifosine bulk substance and/or finished dosage form
(tablets) for commercial production, Zentaris shall transfer all Zentaris Know-How to enable AOI or a third-party manufacturer to
manufacture Perifosine bulk substance and finished dosage form (tablets).

|9.1 | AOI hereby acknowledges that Zentaris is the owner
of all of Zentaris' Patent Rights and AOI shall acquire no rights, title or interest whatsoever in or to any of Zentaris' Patent
Rights, except as specifically provided in the Agreement. Without limiting the generality of this Section 9.1, AOI shall not
utilize any Zentaris' Patent Rights for any purpose whatsoever, except as specifically authorized in this Agreement. AOI shall not
register, or attempt to register, any of Zentaris' Patent Rights, or otherwise assert any ownership rights with respect to any of
Zentaris' Patent Rights, in any country within the Territory.

|9.2 | During the term of this Agreement, Zentaris shall
be responsible for timely prosecuting the patent applications comprised within Zentaris' Patent Rights and for maintaining the
patents comprised within Zentaris' Patent Rights using counsel with whom AOI has no reasonable objection. AOI shall at Zentaris'
request and cost take such actions, and shall provide Zentaris with such assistance, as Zentaris shall reasonably request in order
to protect, perfect, maintain and prosecute Zentaris' rights, title and interests in and to all of Zentaris' Patent Rights within
the Territory. AOI shall bear the external costs reasonably incurred by Zentaris in relation to prosecution of the patent
applications comprised within Zentaris' Patent Rights and maintenance of the patents comprised within Zentaris' Patents Rights,
which relate exclusively to Perifosine in the Territory.

|9.3 | Zentaris shall keep AOI informed and shall consult
with AOI on an ongoing basis regarding prosecution of the patent applications comprised within Zentaris' Patent Rights and
maintenance of the patents comprised within Zentaris' Patent Rights and any actions which are required to be taken in relation
thereto. Zentaris shall keep AOI informed of the filings, prosecution, and maintenance reasonably in advance
of any relevant actions and deadlines and take reasonable account of all comments received from AOI in
relation to prosecution of the patent applications comprised within Zentaris' Patent Rights and maintenance of the patents
comprised within Zentaris' Patent Rights and any actions, which are required to be taken in relation thereto. AOI shall furnish
Zentaris with at least thirty (30) days written notice prior to the First Commercial Sale of any of the Contract Products in any
country within the Territory, in order to permit Zentaris to take such action as Zentaris, in its sole discretion, determines to be
necessary or appropriate to protect and perfect Zentaris' rights, title and interests in and to all of Zentaris' Patent Rights in
that country.
|9.4 | In the event that Zentaris, during the term of
this Agreement, shall desire to sell single Zentaris' Patent Rights Zentaris shall give to AOI first opportunity to purchase the
same at a price to be mutually agreed upon, which price shall not be greater than that which such Zentaris' Patent Right is offered
for sale to any other purchaser. For the sake of clarity, such first opportunity to purchase Zentaris' Patent Rights shall only
apply to single Zentaris' Patent Rights and shall not apply in case of acquisition of all or substantially all of Zentaris'
assets.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
|9.5 | In the event that Zentaris elects not to continue
prosecuting or maintaining any of  Zentaris' Patent Rights listed in Exhibit 1.24 hereto, Zentaris shall give to AOI, if
possible, sixty (60) days, but in any event not less than thirty (30) days, written notice before any relevant deadline relating to
or any public disclosure of the relevant Zentaris' Patent Rights in the Territory.  Upon receipt of a notice from Zentaris
indicating that it intends to cease prosecuting or maintaining any of the Zentaris' patent rights, AOI shall have the right to
continue, at its own expense, prosecution or maintenance (as the case may be) of the relevant Zentaris' Patent Rights in the
Territory and Zentaris shall at the request and cost of AOI do all such acts and execute all such documents as may be necessary to
(i) transfer title to the relevant Zentaris' Patent Rights in the Territory to AOI and (ii) assist AOI with the prosecution and
maintenance of the Zentaris' Patent Rights until such times as AOI's title as proprietor of Zentaris' Patent Rights in the
Territory has been registered at all of the appropriate patent offices.

|9.6  | Each Party shall furnish the other with timely
written notice of any and all infringements and other unauthorized uses by any other person, firm, corporation or other entity of
any of Zentaris' Patent Rights that come to its attention during the continuance of this Agreement. Zentaris, as the owner of all
of Zentaris' Patent Rights, shall be responsible for taking all actions, in the courts, administrative agencies, or otherwise, to
prevent or enjoin any and all such infringements and other unauthorized uses of Zentaris' Patent Rights, using counsel with whom
AOI has no reasonable objection, and AOI shall take no action with respect to any such infringement or unauthorized use of
Zentaris' Patent Rights, without the prior written authorization of Zentaris; provided, however, that AOI shall provide at the
request and cost of Zentaris such assistance as Zentaris shall reasonably request in connection with any action to prevent or
enjoin any such infringement or unauthorized use of any of Zentaris' Patent Rights. Zentarisshall act at its
own discretion and expense and any recovery obtained shall be first applied to pay Zentaris' legal fees and the remainder shall be
deemed Net Sales.Zentaris shall keep AOI informed and shall consult with AOI on an on-going basis regarding
the development and progress of any such action, including, without limitation, permitting AOI's counsel to participate in all
proceedings upon cost of AOI (e.g. hearings, depositions, trials, etc.).  In no event shall Zentaris settle any action or
claim that would impair or prejudice any of AOI's rights granted herein without written consent from AOI, such consent not to be
unreasonably withheld. In the event (A) Zentaris is unable or unwilling to cause such infringement to
terminate or to sue the alleged infringer within (i) one hundred twenty (120) days of the date of notice of such infringement, or
(ii) thirty (30) days before the time limit, if any, set forth in the appropriate laws and regulations for the filing of such
actions, whichever comes first, or (B) AOI requires immediate injunctive relief for breach of its exclusive license and Zentaris,
after being informed by AOI of the breach and the proposed action, is unable or unwilling to take such immediate action, AOI may,
but shall not be required to take such action as AOI may deem appropriate to prevent or enjoin the alleged infringement or
threatened infringement of a Zentaris'Patent Right. In such event, AOI shall act at its
own discretion and expense, and Zentaris shall co-operate reasonably with AOI, at the expense of AOI, and Zentaris agrees to be
named as a nominal party. In the event of such action by AOI, any recovery obtained shall be paid to AOI. If such action of AOI is
successful, any recovery obtained shall be first applied to pay AOI's reasonable legal fees and the remainder shall be deemed Net
Sales. If the reasonable legal fees exceed the recovery obtained, AOI is entitled to credit such excess fees against royalties due
by AOI hereunder but in no event more than [*****] percent ([**]%) percent of any payment, e.g., if the expenses are $[****], recovery is $[***]
and the monthly royalty is $[**], AOI may credit $[***] against $[**] for [**] months.

|10.3 | Joint patent rights shall be filed in the name of both Parties and each
    Party shall procure that its respective inventors assign all of their rights
    and interests to such joint patent rights to both Parties.  Each Party
    shall be free to use and exploit the joint patent rights for any purpose
    whatsoever within their respective territories.  Neither Party shall
    grant licenses of the joint patent rights to any Third Party without the
    other Partys prior written consent and on terms and conditions to be agreed
    with the other Party acting reasonably.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
|10.4 | In each case, whichever Party files, prosecutes, and maintains the joint
    patent rights shall keep the other Party informed of the filings,
    prosecution, and maintenance reasonably in advance of any relevant actions
    and deadlines to allow for review and consultation. In the event
that the prosecuting partyelects not to continue prosecuting or maintaining any of the
joint patent rights, the prosecuting party shall give to the other Party, if possible,
sixty (60) days, but in any event not less than thirty (30) days, written notice before any relevant deadline relating to or any
public disclosure of the relevant joint patent rights.  Upon receipt of a notice from the prosecuting
party indicating that it intends to cease prosecuting or maintaining any of the joint patent rights, the other
Party shall have the right to continue, at its own expense, prosecution or maintenance (as the case may be) of the relevant patent
rights and the prosecuting party shall at the request and cost of the other Party do all
such acts and execute all such documents as may be necessary to assist the other Party with the prosecution and maintenance of the patent rights.

this Agreement or are otherwise bound by obligations of confidentiality. The Receiving Party shall furnish the Disclosing Party
with immediate written notice of any unauthorized use or disclosure of any of the Disclosing Party's Confidential Information by
any officer, employee or sublicensee of the Receiving Party, and shall take all actions that the Disclosing Party reasonably

without limitation, any warranty or merchantability of fitness for a particular purpose.

|13.4 | Other than Miltefosine, Zentaris is not currently developing
an alklyphospholipid and will notify AOI if in the future it does commence developing or acquire an alkylphospholipid and will keep
AOI aware of the development status of such product on a continuing basis.  In the event that Zentaris, during the term of
this Agreement, shall desire to license such product (other than Miltefosine) within the Territory, Zentaris shall, by way of
written notice, give to AOI first opportunity to license the same at a royalty to be mutually agreed upon, which royalty shall not
be greater than that which Zentaris' has offered to any other licensee. In order to exercise such first opportunity, AOI shall
inform Zentaris in writing within four (4) weeks following AOI's receipt of Zentaris' written notice of whether it is interested in
licensing the product at the terms proposed by Zentaris and the Parties shall enter into a binding licensing agreement regarding
such product within eight (8) weeks following AOI's receipt of the written notice by Zentaris.

|     | Zentaris' indemnification obligation under this Section 14.1 shall be subject to each of
the following conditions: (i) AOI shall furnish Zentaris with written notice of any such Claims and Liabilities within thirty (30)
days of the date on which AOI receives notice thereof; (ii) subject to Zentaris confirming in writing that the indemnity will apply
to the relevant Claims and Liabilities, Zentaris shall be solely responsible for the investigation, defense, settlement and
discharge of such Claims and Liabilities; and (iii) AOI shall at Zentaris’ cost furnish Zentaris with all assistance
reasonably requested by Zentaris in connection with the investigation, defense, settlement and discharge of such Claims and
Liabilities. AOI's failure to comply with its obligations pursuant to this Section 14.1 shall not constitute a breach of this
Agreement or relieve Zentaris of its indemnification obligations pursuant to this Section 14.1, except to the extent, if any, that
Zentaris' defense of the effective claim, action or proceeding actually was materially impaired thereby.                                                                                                                                                                                                                                                                                                     
|14.2 | In the event that it is determined by any court of competent
jurisdiction that AOI's use of Zentaris' Patent Rights and/or Zentaris' Know-How in accordance with the terms and conditions of
this Agreement infringes, or Zentaris reasonably determines that AOI's use of Zentaris' Patent Rights and/or Zentaris' Know-How is
likely to infringe, any United States, Canadian or Mexican patent, copyright, trademark, data exclusivity right or trade secret
right of any other person, firm, corporation or other entity, Zentaris shall in consultation with AOI use commercially reasonable
efforts to: (i) procure at Zentaris'expense a license from such other person, firm, corporation or other
entity authorizing AOI to continue to utilize Zentaris'Patent Rights; or (ii) modify Zentaris'Patent Rights and/or Zentaris'Know-How, so as to render it non-infringing.  In the event that
neither of the foregoing alternatives is reasonably available or commercially feasible, AOI may at its option either cease using
Zentaris'Patent Rights and/or Zentaris'Know-How for so long as and to the extent that
Zentaris'Patent Rights and/or Zentaris'Know-How are infringing the relevant third party
rights or terminate the rights and licenses granted to AOI solely with respect to that country or those countries in which the
infringement of third party rights has occurred or is likely to occur.

|14.3 | Zentaris' obligations under Sections 14.1 and 14.2 hereof
shall not apply to any allegations of infringement of the intellectual property rights of another person, firm, corporation or
other entity that would not have arisen but for: (i) AOI's use of Zentaris Patent Rights and/or Zentaris' Know-How in violation of
the terms and conditions of this Agreement; (ii) any modification, adaptation or application of Zentaris' Know-How made by AOI
without the prior authorization of Zentaris; or (iii) any combination of the Contract Products with any other products, compounds
or materials but only if the allegation of infringement does not relate to Perifosine.

    obligations under Section 3.1 above and the failure to comply with the time

    forth in the development plan as set forth under Section 5 above - the other
    party hereto (the "non-breaching party") may give the breaching party
    written notice of such material breach or default, and shall request that

    within ninety (90) days after the date of the non-breaching party's notice
    thereof, the non-breaching party may terminate this Agreement by giving

other Party is declared insolvent by a judicial body, undergoes voluntary or involuntary dissolution, or makes an assignment for
the benefit of its creditors or suffers the appointment of a receiver or trustee over all, or substantially all, of its assets or
properties.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
|15.5 | Except as set out in Section 15.10 hereof, immediately upon
the expiration or termination of this Agreement for any reason whatsoever, AOI shall cease all manufacture, production,
distribution, marketing and sale of the Contract Products under the licenses granted hereunder; provided, however, that, if this
Agreement is terminated for any reason other than a breach or default hereunder by AOI, AOI shall have the right to distribute and

date of expiration or termination hereof, subject to AOI's continuing obligation to pay royalties with respect to the Net Sales

CRADA within a period of one (1) month after the termination date. If, in this case Regulatory Approvals have not been obtained by
AOI, Zentaris may claim from AOI that AOI transfers to Zentaris the status of an applicant for the Regulatory Approvals and
notifies the competent regulatory authority thereof and supplies Zentaris with all documents already prepared by AOI for the filing
of applications for Regulatory Approvals.                                                                                                                                                                                                                                                                                          
|15.9  | In the event of termination of this Agreement by AOI pursuant
to Section 15.3 or Section 15.4 then (i) the license rights contained in Section 2.1 shall continue in full force and effect (ii)
AOI's obligations under Sections 3, 4.2, 5, 6, 7, and 8 hereof shall terminate and (iii) from the date of such termination AOI
shall still be obligated under Section 4.4 but the royalty rates set out in Section 4.4 will be reduced by fifty percent
(50%).                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
|15.10 | In the event of a refusal by the competent government agencies of any
country within the Territory to issue any required Regulatory Approvals to AOI for the manufacture, production, distribution,
marketing, sale and/or use of the Contract Products within that country, the Parties shall meet to reassess the development plan
and set forth appropriate time periods to meet additional clinical studies or other requirements set by the government agency to be
necessary for Regulatory Approval. If the refusal by the government agencies is subject to a permanent denial (without the right to
appeal or produce additional data to support approval), Zentaris shall have the right to remove that country from the Territory by
furnishing written notice thereof to AOI, at any time after Zentaris' receipt of AOI's written notice under this Section 15.10 of
the occurrence of such refusal.                                                                                                                                                                                                                                                                                    
|16.   | General Provisions                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
|16.1  | AssignmentSubject to the other
terms of this Agreement, neither Party shall have the right or the power to assign any of its rights, or delegate the performance
of any of its obligations under this Agreement, without the prior written authorization of the other Party, such written
authorization not to be unreasonably withheld or delayed; provided, however, that the prior written authorization of the other
Party shall not be required for a Party to assign any of its rights, or delegate the performance of any of its obligations
hereunder to an Affiliate or an acquirer of all or substantially all of the assets of the company.  Any permitted assignment
or delegation hereunder by either Party, whether to an Affiliate or an acquirer pursuant to this Section 16.1 or pursuant to the
prior written authorization of the other Party, shall not relieve such Party of any of its obligations under this Agreement,
including, but not limited to, the Party's obligation to make royalty payments with respect to any and all Net Sales derived by any
of the Party's assignees or sublicensee from the distribution, marketing and sale of any of the Contract Products.

|16.2 | Force MajeureNeither party shall be
liable for any failure to perform, or any delay in the performance of, any of its obligations under this Agreement to the extent,
but only to the extent, that such party's performance is prevented by the occurrence of an event of force majeure. For purposes of
this Section 16.2, an event of force majeure shall mean and include, war, civil war, insurrection, rebellion, civil unrest, fire,
flood, earthquake, adverse weather conditions, strike, lockout, labor unrest, unavailability of supplies, materials or
transportation, acts of the public enemy, acts of terrorism, acts of government authorities (including, but not limited to, the
refusal of the competent government agencies to issue required Regulatory Approvals), and, in general, any other cause or condition
beyond the reasonable control of the party whose performance is affected thereby. In the event that a party's performance is
affected by the occurrence of any event of force majeure, that party shall furnish immediate written notice thereof to the other
party hereto.
