Sales between Ohm and its Affiliates and sublicensees shall be disregarded for purposes of calculating Net Sales except if such purchaser is an end user.

With respect to any sale of any Product in a given country for less than fair market value or for any substantive consideration other than monetary consideration on arm’s length terms (which has the effect of reducing the invoiced amount below what it would have been in the absence of such non-monetary consideration), for purposes of calculating the Net Sales under this Agreement, such Product shall be deemed to be sold exclusively for cash at the average price charged to Third Parties for cash sales in such country during the applicable reporting period (or if there were only de minimis cash sales in such country, at the fair market value as determined in good faith based on pricing in comparable markets). Notwithstanding the foregoing, Net Sales shall not include amounts (whether actually existing or deemed to exist for purposes of calculation) for Products distributed at no charge for use in clinical trials or as complimentary samples.

Net Sales shall be calculated on an accrual basis, in a manner consistent with the selling party’s accounting policies for external reporting purposes, as consistently applied, in accordance with IFRS. To the extent any accrued amounts used in the calculation of Net Sales are estimates, such estimates shall be trued-up in accordance with Ohm’s accounting policies for external reporting purposes, as consistently applied, and Net Sales and related payments under this Agreement shall be reconciled as appropriate.

Ohm and its Affiliates and sublicensees shall not sell any Product in combination with or as part of a bundle with other products, or offer packaged arrangements to customers that include a Product, in such a manner as to disproportionately discount the selling price of such Product as compared with the weighted-average discount applied to the other products, as a percent of the respective list prices (or if not available, a good faith estimate thereof) of such products and such Product prior to applying the discount.

Net Sales for a Combination Product in a country shall be calculated as follows:

(i) If the Licensed Compound in such Combination Product and the Other Active(s) each are sold separately in such country in the applicable calendar year, Net Sales will be calculated by multiplying the total Net Sales (as defined above) of the Combination Product by the fraction A/(A+B), where A is the public or list price in such country of the Licensed Compound sold separately in the same formulation and dosage, and B is the (sum of the) public or list price(s) in such country of the Other Active(s) sold separately in the same formulation and dosage, during the applicable calendar year.

(ii) If such Licensed Compound is sold independently of the Other Active(s) in such country in such calendar year, but the public or list price in such country of the Other Active(s) cannot be determined, Net Sales will be calculated by multiplying the total Net Sales (as defined above) of such Combination Product by the fraction A/C, where A is the public or list price in such country of such Licensed Product sold independently and C is the public or list price in such country of the Combination Product during the applicable calendar year.

(iii) If the public or list price in such country of such Licensed Compound cannot be determined, then the Parties shall discuss in good faith and determine the amount to be included in Net Sales, based on a reasonable allocation of the relative values of the Other Active(s) and such Licensed Compound.

Notwithstanding the foregoing, in no event will the Net Sales for any Combination Product and any country be reduced on account of the foregoing clauses (i), (ii) and (iii) to less than sixty-six percent (66%) of the total Net Sales defined above prior into account clauses (i), (ii) and (iii).

LICENSES

2.1 Licenses to Ohm under Aptose IP. Subject to the terms and conditions of this Agreement, Aptose hereby grants to Ohm an exclusive (even as to Aptose), royalty-bearing, sublicenseable (solely as provided in Section 2.2) license under the Aptose IP: (a) to Develop, make, have made and import Licensed Compounds in the Field in the Territory for the sole purpose of Developing, making, importing, offering for sale, selling and otherwise Commercializing Products in the Field in the Territory; and (b) to Develop, make, have made, import, offer for sale, sell and otherwise Commercialize Products in the Field in the Territory. The foregoing license does not include any rights for Ohm directly or indirectly to (i) screen compounds for inhibition of kinase enzymes of the FLT3 family or the BTK family, except for the activities expressly described in Sections 2.2(b) and 4.2(c) or (ii) optimize compounds for inhibition of kinase enzymes of the FLT3 family or the BTK family. Ohm shall not, and shall ensure that its Affiliates, sublicensees and subcontractors do not, conduct any of the activities described in the preceding sentence.

2.2 Sublicenses.

(a) Sublicense Rights. Subject to the terms and conditions of this Agreement, and provided that (i) Ohm has complied with its obligations under Sections 2.2(b), 2.3 and 2.4 and (ii) Aptose has no further rights under Section 2.3 or 2.4 with respect to the applicable sublicense scope, Ohm shall have the right to grant sublicenses of the license granted to it under Section 2.1 to its Affiliates and Third Parties. Each sublicense granted by Ohm shall be consistent with the terms and conditions of this Agreement and shall require such sublicensee to assign to Ohm, or to grant Ohm an exclusive, sublicenseable, worldwide license under, all of such sublicensee’s interest in Patent Rights and Know-How that, if Controlled by Ohm, would be Ohm IP, and shall permit such sublicensee to grant further sublicenses only under the foregoing conditions. Ohm shall be solely responsible for all of its sublicensees’ (and their further sublicensees’) activities, including any and all failures by such sublicensees to comply with the applicable terms and conditions of this Agreement. Prior to granting a sublicense to a Third Party, Ohm shall notify Aptose of the applicable Third Party and scope of the anticipated sublicense and shall provide to Aptose a copy of the substantially agreed or executed term sheet, containing all material terms of the anticipated sublicense agreement, promptly upon availability thereof. Within thirty (30) days after the grant of a sublicense, Ohm shall notify Aptose and, if such sublicense is granted to a Third Party, shall provide Aptose with a true and complete copy of the sublicense agreement; provided, however, the sublicense agreement may be redacted with respect to information that is not necessary to disclose to Aptose in order to ensure Ohm’s compliance with this Agreement.

(b) Compound Testing. Prior to initiating discussions or negotiations with any Third Party or with Aptose with respect to the grant of a sublicense under the license granted in Section 2.1, Ohm shall conduct characterization studies of all compounds that would be included in the sublicense to determine their kinase inhibitory profile, including the inhibition of specific forms of FLT3 (FLT3-ITD, FLT3-D835Y, FLT3-ITD+D835Y, FLT3-ITD+F691L) and of BTK (BTK-wild type, BTK-C481S) using the standard assay conditions performed by Reaction Biology Corporation or equivalent procedure to characterize the molecules. Based on the results of such studies, Ohm shall identify each tested compound as either a ROFN Product or a ROFR Product, and shall provide Aptose with the results of each such test, including such identification, promptly after completion thereof.

2.3 Aptose’s Right of First Negotiation for Licensed Compounds that do not Inhibit BTK and/or FLT3. Ohm hereby grants Aptose a right of first negotiation for each ROFN Product as follows. Prior to entering into any negotiations with a Third Party with respect to a license or sublicense under Ohm’s rights to any ROFN Product(s), Ohm shall notify Aptose and provide all information useful for Aptose to determine its interest in such ROFN Product(s). If Aptose notifies Ohm in writing of its interest in such ROFN Product(s) within fourteen (14) business days after receipt of all such information from Ohm, the Parties shall negotiate exclusively and in good faith for a period of up to three (3) months (or such longer period as agreed by the Parties in writing) (the “ROFN Negotiation Period”) a term sheet for a license to Aptose to Develop and Commercialize such ROFN Product(s). If the Parties fail to reach agreement on a term sheet during the ROFN Negotiation Period, Ohm shall have the right to negotiate the terms of and enter into a license agreement for the applicable ROFN Product(s), for the scope offered to Aptose, with any Third Party. If, during the ROFN Negotiation Period, the Parties agree to the terms of such term sheet, the Parties shall negotiate in good faith for an additional three (3)-month period, commencing on the date the term sheet is signed by both Parties, to conclude a definitive agreement, and during such period, Ohm shall not enter into any discussions or negotiations with, and shall not provide any confidential information to, a Third Party with respect to a license or sublicense under Ohm’s rights to the applicable ROFN Product(s). For clarity, this Section 2.3 will apply to each ROFN Product and territory that Ohm desires to license to a Third Party.

2.4 Aptose’s Right of First Refusal for Licensed Compounds that Inhibit BTK and/or FLT3. Ohm hereby grants Aptose a right of first refusal for each ROFR Product as follows. Prior to entering into any negotiations with a Third Party with respect to a license or sublicense under Ohm’s rights to any ROFR Product(s), Ohm shall notify Aptose and provide all information useful for Aptose to determine its interest in such ROFR Product(s). If Aptose notifies Ohm in writing of its interest in such ROFR Product(s) within fourteen (14) business days after receipt of all such information from Ohm, the Parties shall negotiate exclusively and in good faith for a period of up to six (6) months (or such longer period as agreed by the Parties in writing) (the “ROFR Negotiation Period”) the terms of a license to Aptose to Develop and Commercialize such ROFR Product(s). If Aptose does not notify Ohm of its interest in such ROFR Product(s) during the applicable time period, or notifies Ohm that it is not interested in such ROFR Product(s), or if Aptose notifies Ohm of its interest in such ROFR Product(s) and the Parties fail to reach agreement on the terms of a license during the ROFR Negotiation Period, then in each case Ohm shall not enter into an agreement with a Third Party with respect to such ROFR Product(s) without first offering the same terms, as set forth in a term sheet signed by Ohm and the Third Party, to Aptose for a period of thirty (30) days, commencing on the date on which Ohm provides to Aptose all information then available that is useful for Aptose to determine its then-current interest in such ROFR Product(s), including all information that has been provided or made available to the applicable Third Party (the “Review Period”). If Aptose accepts such terms in writing within the Review Period, then Ohm shall not enter into an agreement with the applicable Third Party, and instead the Parties shall promptly enter into a license agreement for the applicable ROFR Product(s). If Aptose does not accept such terms in writing within the Review Period, then Ohm shall have no further obligations, and Aptose shall have no further rights, with respect to the applicable ROFR Product(s) and territory under this Section 2.4, and Ohm may enter into an agreement with a Third Party with respect to such ROFR Product(s) and territory. For clarity, this Section 2.4 will apply to each ROFR Product and territory that Ohm desires to license to a Third Party.

6. First NDA Approval for a Product in the U.S.	[*]	[*]
7. First MAA Approval for a Product outside the U.S.	[*]	[*]

(b) Clarifications.

(i) Each milestone payment set forth above shall be due one time only for the first Product and one time only for the second Product, each in the applicable amount, and regardless of whether different milestone events are achieved by the same or different Products. If Ohm or its Affiliate or sublicensee terminates Development of a Product after achievement of one but not all milestone events, then milestone payments will be paid for achievement by subsequent Products, either at the amount for the first Product (if not previously achieved by any Product) or at the amount for the second Product (if previously achieved by one Product).

(ii) The maximum total amount payable under Section 6.3(a) is $38,750,000, if each milestone event is achieved (or otherwise payable) by one Product only and an additional $19,375,000 if each milestone event is achieved (or otherwise payable) by two Products.

(iii) In the event that any of milestone event numbers 1 through 3 has not been achieved at the time of achievement of a milestone event having a higher number than the skipped milestone event, then each skipped milestone event shall be deemed achieved at the time of achievement of the higher number milestone event, and Ohm shall pay to Aptose the milestone payment for such skipped milestone event within forty five (45) days after the achievement of the higher number milestone event.

6.4 Sales Milestone Payments. Ohm shall pay to Aptose the one-time, non-refundable, non-creditable sales milestone payments set forth below, in each case within forty five (45) days after the end of the first calendar quarter during which the aggregate annual Net Sales of a Product in the Territory first reach the values indicated below for the first two Products to reach such threshold. Milestone events for the first Product or the second Product need not be achieved by the same Product. For clarity, the milestone payments in this Section 6.4 shall be additive such that if multiple milestone events specified below are achieved in the same calendar quarter, then the milestone payments for all such milestone events shall be payable within forty five (45) days after the end of such quarter.

Annual Net Sale of a Product in the Territory	Milestone Payments
Annual Net Sale of a Product in the Territory	First Product	Second Product
Equal or exceed $250,000,000	[*]	[*]
Equal or exceed $500,000,000	[*]	[*]
Equal or exceed $750,000,000	[*]	[*]
Total	$45,000,000	$22,500,000

6.5 Royalty Payments for Products.

(a) Royalty Rates. Subject to the other terms of this Section 6.5, Ohm shall make calendar quarterly, non-refundable, non-creditable royalty payments to Aptose on the Net Sales of all Products sold during the Royalty Terms, as calculated by multiplying the applicable royalty rate set forth below by the corresponding amount of incremental, aggregated Net Sales of all Products sold in the Territory in the applicable calendar year.

Annual Net Sale of all Products in the Territory	Royalty Rate
For that portion of annual Net Sales less than $1,000,000,000	[*]
For that portion of annual Net Sales greater than or equal to $1,000,000,000	[*]

(b) Royalty Term. Ohm’s obligation to pay royalties pursuant to this Section 6.5 shall not apply to Net Sales of Products to the extent that such Net Sales arise from sale of a Product in a particular country after the expiration of the Royalty Term for such Product in such country. For clarity, all such Net Sales will be included for purposes of determining the royalty tiers and royalty rates applicable to Net Sales in other countries.

(c) Royalty Reduction. With respect to Net Sales of a particular Product that arise from the sale of such Product in a particular country in the Territory in a calendar quarter (i) during the Royalty Term for such Product in such country, (ii) in which there is no Valid Claim of any Aptose Patent in such country that claims the composition, manufacture or use of such Product, (iii) in which there is no Regulatory Exclusivity for such Product in such country and (iv) in which the unit volume of all Generic Products to such Product that are sold by Third Parties in such country exceeds thirty percent (30%) of the combined unit volume of such Product and such Generic Product sold in such country during such calendar quarter (which determinations of unit volume shall be based on a mutually acceptable calculation method and using market share data provided by a reputable and mutually agreed upon provider, such as IMS Health), the royalties applicable to such Net Sales will be reduced by fifty percent (50%) of the royalties otherwise payable under Section 6.5(a). For example, if during a particular calendar year, the Net Sales in countries in which the royalties are not subject to deduction under this Section 6.5(c) are $1 billion, and Net Sales in countries in which the royalties are subject to deduction under this Section 6.5(c) are $500 million, the following would apply: the royalties without regard to the reduced rate would be [*]. The portion of royalties (without deduction) attributable to countries in which the royalties are subject to deduction is ($500 million / $1.5 billion) x $35 million = $11.67 million, so with the deduction such royalties would be $5.83 million, and the total royalties would be $29.167 million.

(d) Royalty Reports and Payment. Within forty five (45) days after the end of each calendar quarter, commencing with the calendar quarter during which the First Commercial Sale of a Product is made anywhere in the Territory, Ohm shall provide Aptose with a report that contains the following information for the applicable calendar quarter, on a Product-by-Product and country-by-country basis: (i) the amount of gross sales of the Products, (ii) a calculation of Net Sales in the Territory, (iii) a calculation of the royalty payment due on such sales, including the application of any reduction made in accordance with Section 6.5(c), and (iv) the exchange rate for such country. Concurrent with the delivery of the applicable quarterly report, Ohm shall pay Aptose in Dollars all royalties owed with respect to Net Sales for such calendar quarter.

6.6 Currency; Exchange Rate. All payments to be made by Ohm to Aptose under this Agreement shall be made in Dollars by bank wire transfer in immediately available funds to a bank account designated by written notice from Aptose. The rate of exchange to be used in computing the amount of currency equivalent in Dollars shall be made at the average of the closing exchange rates reported in The Wall Street Journal (U.S., Eastern Edition) for the first, middle and last business days of the applicable reporting period for the payment due.

6.7 Late Payments. If Aptose does not receive payment of any sum due to it on or before the due date therefor, simple interest shall thereafter accrue on the sum due to Aptose from the due date until the date of payment at a per-annum rate of prime (as reported in The Wall Street Journal (U.S., Eastern Edition)) plus two percentage points or the maximum rate allowable by applicable Law, whichever is less.

6.8 Taxes.

(a) Cooperation and Coordination. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the activities of the Parties under this Agreement. The Parties acknowledge and agree that it is their mutual objective and intent to appropriately calculate, to the extent feasible and legal, taxes payable with respect to their collaborative efforts under this Agreement and that they shall use all Diligent Efforts to cooperate and coordinate with each other to achieve such objective. Ohm shall cooperate with Aptose in seeking any tax exemption or credits that may be available. The Parties agree to cooperate with one another and use reasonable efforts to avoid or reduce tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by Ohm to Aptose under this Agreement.

(b) Payment of Tax. To the extent Ohm is required by applicable Laws to deduct and withhold taxes on any payment to Aptose, Ohm shall promptly notify Aptose. Aptose shall provide Ohm any tax forms that may be reasonably necessary in order for Ohm not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Aptose shall use reasonable efforts to provide any such tax forms to Ohm in advance of the due date. After making reasonable effort to obtain the lowest tax rate, Ohm shall (i) deduct those taxes from the payment; (ii) pay the taxes to the proper taxing authority in a timely manner; and (iii) send evidence of the obligation together with proof of payment to Aptose within ten (10) business days following that payment. Ohm shall also provide Aptose with reasonable assistance to enable the recovery, as permitted by applicable Laws, of withholding taxes or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of Aptose as the Party bearing such withholding tax under this Section. Notwithstanding the foregoing, if as a result of any action by Ohm, including assignment or sublicense, any change in Ohm’s tax residency, any change in the entity that originates the payment, or any failure on the part of Ohm to comply with applicable Laws (including filing or record retention requirements), withholding taxes are imposed that were not otherwise applicable (“Incremental Withholding Taxes”), then Ohm shall be solely responsible for the amount of such Incremental Withholding Taxes and shall increase the amounts payable to Aptose so that Aptose receives a sum equal to the sum it would have received had there been no such action and resulting tax increase.

6.9 Financial Records and Audit. Ohm shall maintain complete and accurate records in sufficient detail to permit Aptose to confirm the accuracy of royalty payments payable under this Agreement and to verify the achievement of milestone events under this Agreement. Upon reasonable prior notice, such records shall be open during regular business hours for a period of three (3) years from the creation of individual records for examination at Aptose’s expense, and not more often than once each calendar year, by an independent certified public accountant selected by Aptose and reasonably acceptable to Ohm for the sole purpose of verifying for Aptose the accuracy of the financial reports furnished by Ohm pursuant to this Agreement or of any payments made, or required to be made, by Ohm pursuant to this Agreement. Any such auditor shall not disclose Ohm’s confidential information to Aptose, except to the extent such disclosure is necessary to verify the accuracy of the financial reports furnished by Ohm or the amount of payments by Ohm under this Agreement. Any amounts shown to be owed but unpaid shall be paid within thirty (30) days after the accountant’s report, plus interest (as set forth in Section 6.7) from the original due date. Aptose shall bear the full cost of such audit unless such audit reveals an underpayment by Ohm that resulted from a discrepancy in the financial report provided by Ohm for the audited period, which underpayment was more than five percent (5%) of the amount set forth in such report, in which case Ohm shall reimburse Aptose for the costs for such audit.

6.10 Acquisition of Aptose. If Aptose is acquired by another company or if another company acquires over 50% of the shares of Aptose, Aptose and Ohm will meet to renegotiate the terms of the information Ohm is required to share with Aptose under this Article 6. If Ohm has partnered the program this renegotiation shall take into consideration the potential concerns of Ohm’s partner, especially if the company acquiring Aptose is a competitor of Ohm’s partner.

(b) Ohm Sole Patents.

(i) As between the Parties, Ohm shall have the first right to file, prosecute and maintain the Ohm Patents that are not Joint Patents (“Ohm Sole Patents”) in the Territory, at Ohm’s cost and expense.

(ii) Ohm shall consult with Aptose and keep Aptose reasonably informed of the status of all Ohm Sole Patents in the Territory and shall promptly provide Aptose with material correspondence received from patent authorities in connection therewith. In addition, Ohm shall promptly provide Aptose with drafts of all proposed material filings and correspondence to the patent authorities with respect to the Ohm Sole Patents in the Territory for Aptose’s review and comment prior to the submission of such proposed filings and correspondence. Ohm shall confer with Aptose and consider in good faith Aptose’s comments prior to submitting such filings and correspondence, provided that Aptose shall provide such comments within fourteen (14) days (or a shorter period reasonably designated by Ohm if fourteen (14) days is not practicable given the filing deadline) of receiving the draft filings and correspondence from Ohm.

(iii) Ohm shall notify Aptose of any decision to cease prosecution and/or maintenance of, or not to continue to pay the expenses of prosecution and/or maintenance of, any Ohm Sole Patent in the Territory. Ohm shall provide such notice at least thirty (30) days prior to any filing or payment due date, or any other due date that requires action, in connection with such Ohm Sole Patent. In such event, Ohm shall permit Aptose, at its discretion and at its sole expense, to continue prosecution or maintenance of such Ohm Sole Patent.

(c) Cooperation. Aptose agrees to cooperate fully in the preparation, filing, prosecution and maintenance of Patents under this Section 7.3, at Ohm’s request and expense. Such cooperation includes executing all papers and instruments, or requiring its employees or contractors, to execute such papers and instruments, so as enable Ohm to apply for and to prosecute patent applications in any country as permitted by Section 7.3.

7.4 Patent Enforcement.

(a) Each Party shall notify the other promptly after becoming aware of any alleged or threatened infringement by a Third Party of any Aptose Patent, Ohm Patent or Joint Patent through the using, making, importing, exporting, offering for sale or selling of any Product in the Field, including any “patent certification” filed in the United States under 21 U.S.C. §355(b)(2) or 21 U.S.C. §355(j)(2) with respect to the Product and Field or similar provisions in other jurisdictions (collectively “Product Infringement”), or of any alleged or threatened infringement by a Third Party of any Joint Patent that is not a Product Infringement.

(b) Ohm shall have the first right to bring and control any legal action in connection with any Product Infringement of any Aptose Patent or Joint Patent in the Territory, or any other infringement of a Joint Patent in the Territory, at its own expense as it reasonably determines appropriate, and Aptose shall have the right to be represented in any such action by counsel of its choice. If Ohm does not bring such legal action within sixty (60) days after the notice provided pursuant to Section 7.4(a), Aptose shall have the right to bring and control any legal action in connection with such Product Infringement or other infringement of a Joint Patent in the Territory at its own expense as it reasonably determines appropriate.

(c) Ohm shall have the first right to bring and control any legal action in connection with any Product Infringement of an Ohm Patent in the Field in the Territory at its own expense as it reasonably determines appropriate.

(d) At the request and expense of the Party bringing the action under Section 7.4(b) above, the other Party shall provide reasonable assistance in connection therewith, including by executing reasonably appropriate documents, cooperating in discovery and joining as a party to the action if required. In connection with any such proceeding, the Party bringing the action shall not enter into any settlement admitting the invalidity of, or otherwise impairing the other Party’s rights in, the Aptose Patents or Joint Patents without the prior written consent of the other Party.

(e) Any recoveries resulting from an enforcement action under Section 7.4(b) or 7.4(c) against a Product Infringement in the Field in the Territory shall be first applied against payment of each Party’s costs and expenses in connection therewith. For an enforcement action under Section 7.4(b), any recoveries in excess of such costs and expenses (the “Remainder”) shall be shared by the Parties as follows: seventy-five percent (75%) of such Remainder shall be retained by the Party bringing such action, and twenty-five percent (25%) of such Remainder shall be paid to the Party not bringing such action.

7.5 Trademarks. Ohm shall have the right to brand the Products in the Field in the Territory using Ohm related trademarks and any other trademarks and trade names it determines appropriate for the Products, which may vary by country or within a country (“Product Marks”). Ohm shall own all rights in the Product Marks and shall register and maintain the Product Marks in the countries and regions that it determines reasonably necessary, at Ohm’s cost and expense.

7.6 Personnel Obligations. Prior to beginning work under this Agreement relating to any Development of Licensed Compounds or Products, each employee, agent or independent contractor of Ohm and its Affiliates shall be bound by invention assignment obligations that are consistent with the obligations of Ohm in this Article 7, including: (a) promptly reporting any Invention; (b) assigning to Ohm, as applicable, all of his or her right, title and interest in and to any Invention; (c) cooperating in the preparation, filing, prosecution, maintenance and enforcement of any Patent Right; (d) performing all acts and signing, executing, acknowledging and delivering any and all documents required for effecting the obligations and purposes of this Agreement; and (e) complying with obligations of confidentiality and non-use consistent with those contained in this Agreement.

Article 8

CONFIDENTIALITY; PUBLICATION

8.1 Duty of Confidence. Subject to the other provisions of this Article 8:

(a) all Confidential Information disclosed by a Party (the “Disclosing Party”) or its Affiliates under this Agreement shall be maintained in confidence and otherwise safeguarded by the recipient Party (the “Receiving Party”) and its Affiliates, in the same manner and with the same protection as such Receiving Party maintains its own confidential information;

(b) the Receiving Party may only use any such Confidential Information for the purposes of performing its obligations or exercising its rights under this Agreement; and

(c) the Receiving Party may disclose Confidential Information of the other Party to: (i) its Affiliates and sublicensees; and (ii) employees, directors, agents, contractors, consultants and advisers of the Receiving Party and its Affiliates and sublicensees, in each case to the extent reasonably necessary for the purposes of, and for those matters undertaken pursuant to, this Agreement; provided that such Persons are bound to maintain the confidentiality of the Confidential Information in a manner consistent with the confidentiality provisions of this Agreement.

8.2 Exceptions. The foregoing obligations as to particular Confidential Information of a Disclosing Party shall not apply to the extent that the Receiving Party can demonstrate that such Confidential Information:

(a) is known by the Receiving Party at the time of its receipt without an obligation of confidentiality, and not through a prior disclosure by the Disclosing Party, as documented by the Receiving Party’s business records;

(b) is in the public domain before its receipt from the Disclosing Party, or thereafter enters the public domain through no fault of the Receiving Party;

(c) is subsequently disclosed to the Receiving Party by a Third Party who may lawfully do so and is not under an obligation of confidentiality to the Disclosing Party; or

(d) is developed by the Receiving Party independently and without use of, or reference to, any Confidential Information received from the Disclosing Party, as documented by the Receiving Party’s business records.

Any combination of features or disclosures shall not be deemed to fall within the foregoing exclusions merely because individual features are published or available to the general public or in the rightful possession of the Receiving Party unless the combination itself and principle of operation are published or available to the general public or in the rightful possession of the Receiving Party.

8.3 Authorized Disclosures. Notwithstanding the obligations set forth in Sections 8.1 and 8.5, a Party may disclose the other Party’s Confidential Information to the extent:

(a) such disclosure is reasonably necessary: (i) to such Party’s directors, attorneys, independent accountants or financial advisors for the sole purpose of enabling such directors, attorneys, independent accountants or financial advisors to provide advice to such Party, provided that in each such case such disclosure is on the condition that such directors, attorneys, independent accountants and financial advisors are bound by confidentiality and non-use obligations substantially consistent with those contained in this Agreement; provided, however, that the term of confidentiality for such directors, attorneys, independent accountants and financial advisors shall be no less than five (5) years; or (ii) to actual or potential investors, acquirors, licensees, sublicensees and other financial or commercial partners solely for the purpose of evaluating or carrying out an actual or potential investment, acquisition or collaboration; provided that in each such case such disclosure is on the condition that such recipients are bound by confidentiality and non-use obligations substantially consistent with those contained in the Agreement; provided, however, that the term of confidentiality for such recipients shall be no less than five (5) years; or

(b) such disclosure is required by Law, judicial or administrative process, provided that in such event such Party shall promptly inform the other Party of such required disclosure and provide the other Party an opportunity to challenge or limit the disclosure obligations. Confidential Information that is disclosed pursuant to this Section 8.3(b) shall remain otherwise subject to the confidentiality and non-use provisions of this Article 8, and the Party disclosing Confidential Information pursuant to Law or court order shall take all steps reasonably necessary, including seeking of confidential treatment or a protective order to ensure the continued confidential treatment of such Confidential Information.

8.4 Scientific Publication. Ohm shall not publish peer reviewed manuscripts, or give other forms of public disclosure such as abstracts and presentations, of results of studies carried out under this Agreement, without the opportunity for prior review by Aptose. Ohm shall provide Aptose the opportunity to review and comment on any proposed publication that relates to any Licensed Compound or Product at least thirty (30) days prior to its intended submission for publication. Aptose shall provide its comments (if any) in writing within fifteen (15) days after Aptose’s confirmed receipt of such proposed publication. Ohm shall consider in good faith any comments thereto provided by Aptose and shall comply with Aptose’s request to remove Aptose Confidential Information from the proposed publication. In addition, Ohm shall delay the submission for a period of up to sixty (60) days in the event that Aptose can demonstrate reasonable need for such delay, including the preparation and filing of a patent application. If Aptose fails to provide its comments to Ohm within such fifteen (15)-day period, Aptose shall be deemed to not have any comments, and Ohm shall be free to publish in accordance with this Section 8.4 after the thirty (30) day period has elapsed. Ohm shall provide Aptose a copy of the manuscript at the time of the submission. Ohm agrees to acknowledge the contributions of Aptose and its employees in all publications as scientifically appropriate.

8.5 Publicity. Each Party shall have the right to issue a press release announcing this Agreement, in the form attached hereto as Exhibit B. Subject to Section 8.3 above, no other disclosure of the existence or the terms of this Agreement may be made by either Party or its Affiliates except as provided in this Section 8.5, except as may be required by applicable Law.

(a) A Party may disclose this Agreement and its terms, and material developments or material information generated under this Agreement, in securities filings with the U.S. Securities and Exchange Commission (or equivalent foreign agency) to the extent required by applicable Law after complying with the procedure set forth in this Section 8.5(a). In such event, the Party seeking such disclosure shall prepare a draft confidential treatment request and proposed redacted version of this Agreement to request confidential treatment for this Agreement, and the other Party agrees to promptly (and in any event, no less than seven (7) days after receipt of such confidential treatment request and proposed redactions) give its input in a reasonable manner in order to allow the Party seeking disclosure to file its request within the time lines proscribed by applicable Law. The Party seeking such disclosure shall reasonably consider any comments thereto provided by the other Party within such seven (7) day period.

(b) Each Party acknowledges that the other Party may be legally required to make public disclosures (including in filings with the Governmental Authorities) of certain material developments or material information generated under this Agreement and agrees that each Party may make such disclosures as required by Law, provided that the Party seeking such disclosure first provides the other Party a copy of the proposed disclosure and reasonably considers any comments thereto provided by the other Party within three (3) days after the receipt of such proposed disclosure.

(c) Other than the press release set forth in Exhibit B, and except for public disclosures under Section 8.5(b), the Parties agree that any other news release or other public announcement relating to this Agreement or the performance hereunder that would disclose information other than that already in the public domain, shall first be reviewed and approved by both Parties (with such approval not to be unreasonably withheld or delayed). The Parties agree that after a disclosure pursuant to Section 8.5(b), or after a press release (including the initial press release) or other public announcement pursuant to this Section 8.5(c) has been reviewed and approved by the other Party, the disclosing Party may make subsequent public disclosures reiterating such information without having to obtain the other Party’s prior consent and approval.

8.6 Equitable Relief. Given the nature of the Confidential Information and the competitive damage that would result to a Party upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the Parties agree that monetary damages would not be a sufficient remedy for any breach of this Article 8. In addition to all other remedies, a Party shall be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened breach of this Article 8.

10.2 Indemnification by Ohm. Ohm shall indemnify, defend and hold Aptose, its Affiliates and their respective officers, directors, agents and employees (“Aptose Indemnitees”) harmless from and against Losses incurred as a result of any Claims against them to the extent arising or resulting from (a) the Development, Manufacture or Commercialization of Licensed Compounds and Products by or on behalf of Ohm or any of its Affiliates or sublicensees; (b) the negligence or willful misconduct of any of the Ohm Indemnitees; (c) the breach of any of the warranties or representations made by Ohm to Aptose under this Agreement; or (d) the breach by Ohm of its obligations pursuant to this Agreement; except, in each case (a)-(d), to the extent such Claims result from the breach by Aptose of any covenant, representation, warranty or other agreement made by Aptose in this Agreement or the negligence or willful misconduct of any Aptose Indemnitee.

10.3 Indemnification Procedure. If either Party is seeking indemnification under Sections 10.1 or 10.2 (the “Indemnified Party”), it shall inform the other Party (the “Indemnifying Party”) of the Claim giving rise to the obligation to indemnify pursuant to such Section as soon as reasonably practicable after receiving notice of the Claim. The Indemnifying Party shall have the right to assume the defense of any such Claim for which it is obligated to indemnify the Indemnified Party. The Indemnified Party shall cooperate with the Indemnifying Party and the Indemnifying Party’s insurer as the Indemnifying Party may reasonably request, and at the Indemnifying Party’s cost and expense.

10.5 Insurance. Ohm shall procure and maintain insurance, including product liability insurance, with respect to its activities hereunder that is consistent with normal business practices of prudent companies similarly situated at all times during which any Product is being clinically tested in human subjects or commercially distributed or sold. Ohm shall provide Aptose with evidence of such insurance upon request and shall provide Aptose with written notice at least sixty (60) days prior to the cancellation, non-renewal or material changes in such insurance. Such insurance shall not be construed to create a limit of Ohm’s liability with respect to its indemnification obligations under this Article 10.

10.6 Clarification. The Parties and LALS agree that the indemnification obligations under Article 14 of the MSA do not apply to any activities conducted under this Agreement.

Article 11

12.4 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York without reference to any rules of conflict of laws.

12.5 Dispute Resolution

(a) Objective. The Parties recognize that disputes as to matters arising under or relating to this Agreement or either Party’s rights and obligations hereunder may arise from time to time. It is the objective of the Parties to establish procedures to facilitate the resolution of such disputes in an expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in this Section 12.5 to resolve any such dispute if and when it arises.

(b) Resolution by Executive Officers. If an unresolved dispute as to matters arising under or relating to this Agreement or either Party’s rights and obligations hereunder arises, either Party may refer such dispute to the Executive Officers, who shall meet in person or by telephone within thirty (30) days after such referral to attempt in good faith to resolve such dispute. If such matter cannot be resolved by discussion of such officers within such thirty (30)-day period, or such other time period as the Parties may agree in writing, such dispute shall be resolved in accordance with Section 12.5(c).

(c) Arbitration.

(i) If the Parties do not resolve a dispute as provided in Section 12.5(b), and a Party wishes to pursue the matter, each such dispute that is not an Excluded Claim (defined below) shall be resolved by binding arbitration in accordance with the Rules of Arbitration of the International Chamber of Commerce (“ICC”) as then in effect (the “ICC Rules”), which ICC Rules are deemed to be incorporated by reference into this clause, and judgment on the arbitration award may be entered in any court having jurisdiction thereof. The decision rendered in any such arbitration will be final and not appealable.

(ii) The arbitration shall be conducted by a panel of three (3) arbitrators appointed in accordance with the ICC Rules, none of whom shall be a current or former employee or director, or a then-current stockholder, of either Party, their respective Affiliates or any sublicensee. The place of arbitration shall be San Diego, California, U.S., and all proceedings and communications shall be in English.

(iii) It is the intention of the Parties that discovery, although permitted as described herein, will be limited except in exceptional circumstances. The arbitrators will permit such limited discovery necessary for an understanding of any legitimate issue raised in the arbitration, including the production of documents. No later than thirty (30) days after selection of the arbitrators, the Parties and their representatives shall hold a preliminary meeting with the arbitrators, to mutually agree upon and thereafter follow procedures seeking to assure that the arbitration will be concluded within six (6) months from such meeting. Failing any such mutual agreement, the arbitrators will design and the Parties shall follow procedures to such effect.

(iv) Either Party may apply to the arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Either Party also may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that Party pending the arbitration award. The arbitrators shall have no authority to award punitive or any other non-compensatory damages, except as may be permitted by Section 12.7. The arbitrators shall have the power to order that all or part of the legal or other costs incurred by a Party in connection with the arbitration be paid by the other Party. Each Party shall bear an equal share of the arbitrators’ and any administrative fees of arbitration.
