Subject to the terms and conditions contained herein and, in consideration of the payments specified under Clause 6.1, Isis hereby grants to Orasense for the Term a non-exclusive license, including the limited right to grant sublicenses pursuant to Clause 2.5 hereof, in the Field in the Territory to the Isis Delivery Technology to research, develop, make and have made, offer for sale, sell, import and export the Products and the Oral Platform in the Field, subject to any contractual obligations of Isis to Independent Third Parties as of the Effective Date and, unless prohibited by the paragraph below titled Non Competition, contractual obligations to Independent Third Parties that Isis may enter into after the Effective Date (the "Isis Drug Delivery License");

2.2. Subject to the terms and conditions contained herein and, in consideration of the payments specified under Clause 6.1, Isis hereby grants to Orasense for the Term an exclusive license in the Territory to the Isis Development Candidate Technology to manufacture and Commercialize the Development Product, subject to any contractual obligations of Isis to Independent Third Parties as of the Effective Date (the "Isis Development Candidate License").

2.3. In the event, the Isis License granted to Orasense hereunder is restricted or limited by any contractual obligations of Isis or rights of any Independent Third Parties (a) at any time after the Effective Date or (b) as a result of a breach of the noncompetition provision under Clause 11 of the Original License Agreement, Isis shall use reasonable commercial efforts to exclude or, where applicable, to minimize any such restriction or limitation. Except as expressly provided herein, all proprietary rights and rights of ownership with respect to the Isis Intellectual Property shall at all times remain solely with Isis. For the avoidance of doubt, Isis shall not have any obligations to exclude or minimize any restrictions or limitations under any agreement between an Independent Third Party and Isis entered into prior to the Effective Date, unless such restrictions or limitations arise in connection with a breach by Isis of the noncompetition provision under Clause 11 of the Original License Agreement.

To the extent royalty or other compensation obligations to Independent Third Parties that are payable with respect to Isis Intellectual Property would be triggered by the use or proposed use of Isis Intellectual Property by Orasense, its Affiliates and/or sublicensees, Isis will inform Orasense and Elan of such royalty or compensation obligation. If Orasense decides to utilize the Isis Intellectual Property, then Orasense will be responsible for the payment of such royalty or other compensation obligations relating thereto.

2.4. Notwithstanding anything contained in this Agreement to the contrary, Isis shall have the right, and subject to the paragraph below titled Non-Competition, to fully exploit and grant licenses and sublicenses with respect to the Isis Delivery Technology. Isis's rights to exploit and grant licenses referred to in the immediately preceding sentence shall include, without limitation, the right to research, develop, license and Commercialize products.

2.5. Orasense shall not be permitted to (a) encumber any of its rights under the Licenses or the Orasense Collaboration Intellectual Property without the prior written consent of Isis; (b) assign or sublicense any of its rights under the licenses for the Licensed Technologies and the Orasense Collaboration Intellectual Property without the prior written consent of Isis, which consent may be withheld in Isis' sole discretion. Any agreement between Orasense and any permitted third party for the development or exploitation of the Isis Intellectual Property shall be pursuant to a written sublicense agreement and require third party to maintain the confidentiality of all information concerning the Isis Intellectual Property (which confidentiality obligations shall be no less onerous than the confidentiality obligations of the Parties hereunder) and shall permit an assignment of rights by Orasense to Isis in accordance with the terms of this Agreement. Orasense shall remain responsible for all acts and omissions of any sub-licensee, as if they were acts and omissions by Orasense. Rights of permitted third party sublicensees in and to the Isis Intellectual Property shall survive the termination

of the license and sublicense agreements granting said intellectual property rights to Orasense; and Orasense and Isis shall in good faith agree upon the form most advantageous to Isis in which the rights of the sublicensor under any such sublicenses are to be held (which form may include continuation of Orasense solely as the holder of such licenses or assignment of such rights to a third party or parties, including an assignment to Isis).

2.6. Orasense and its sublicensees, if any, shall be solely responsible for ensuring that the research, development, manufacture and Commercialization of the Products within each country of the Territory is strictly in accordance with all legal, regulatory requirements and applicable laws for each country of the Territory.

2.7. When Packaged, and to the extent permitted by law, a Label shall include an acknowledgement that the Product is made under license from Isis. Such acknowledgement shall take into consideration all regulatory requirements and applicable laws in each country of the Territory and Orasense's reasonable commercial requirements. Orasense shall wherever possible give due acknowledgement and recognition to Isis in all printed promotional and other material regarding the Product such as stating that the Product is under license from Isis and that the applicable Isis Intellectual Property has been applied to the Products. Orasense shall consult with and obtain the written approval of Isis as to the format and content of any promotional and other material insofar as it relates to a description of, or other reference to, the application of the Isis Intellectual Property, such approval not to be unreasonably withheld or delayed. The further consent of Isis shall not be required where the format and content of such materials is substantively similar as the materials previously furnished to and approved in writing by Isis.

2.8. Isis shall have the first option to manufacture the active ingredient of the Development Product for Orasense and meet its requirements, and Orasense shall agree to utilize Isis as its sole supplier, subject to the customary terms and conditions contained in a supply agreement to be executed by the parties at a price equal to Isis' actual manufacturing cost plus ten percent (10%). If, despite good faith negotiations, Isis and Orasense do not reach agreement on the terms of such manufacturing agreement within six (6) months from the Parties' commencement of discussion of such terms, then Orasense shall be free to offer a third party terms to manufacture the active ingredient of the Development Product in the Territory, which terms when taken as a whole, are more favorable to Orasense than the principal terms of the last written proposal offered to Orasense by Isis, or by Orasense to Isis, as the case may be.

Orasense shall, or shall cause its sublicensees to, diligently pursue the research and development of the Elan Intellectual Property, Isis Intellectual Property and Orasense Collaboration Intellectual Property and shall use its, and shall cause its sublicensees to use their, commercially reasonable efforts to Commercialize a Product.

Orasense shall, and shall cause its sublicensees to, inform Isis of any writings, dealings and other communications that Orasense and its sublicensees have with the FDA and any other Regulatory Authority with respect to the safety of the Product and the Oral Platform. The Parties shall collaborate in relation to obtaining any required approvals, including Regulatory Approval of any Regulatory Authority in each country in which Commercialization of the Product and the Oral Platform is sought for final Labeling.

5.2. Subject to agreement to the contrary, any and all Marketing Authorizations filed hereunder for Products shall, to the extent owned by Orasense, remain the property of Orasense, provided that Orasense shall allow Isis access thereto to enable Isis to research, develop and Commercialize any product outside the Field. Orasense shall maintain or cause its sublicensees to maintain such Marketing Authorizations at its or their own cost and expense.

5.3. Orasense shall indemnify and hold harmless Isis, its agents and employees from and against all claims, damages, losses, liabilities and expenses to which Isis, its agents, and employees may become subject related to or arising out of Orasense's bad faith, negligence or intentional misconduct in connection with the filing or maintenance of the Marketing Authorizations.

The method of payment shall be by wire transfer to an account specified by Isis and shall be nonrefundable to Orasense. Each payment made to Isis shall be accompanied by a true accounting of all Products sold by Orasense, its Affiliates and its permitted sublicensees, if any, during such quarter. Such accounting shall show, on a country-by-country and Product-by-Product basis, Net Sales, royalties received by Orasense (and the calculation thereof) and each calculation of royalties with respect thereto, including the calculation of all adjustments and currency conversions.

6.3 Orasense shall maintain and keep clear, detailed, complete, accurate and separate records for a period of [***] following the completion of such records so: (i) as to enable any royalties which shall have accrued hereunder to be determined; and (ii) that any deductions made in arriving at the Net Sales can be determined.

6.4 All payments due hereunder shall be made in United States Dollars. Payments due on Net Sales of any Product, royalties received by Orasense with respect to any Product for each calendar quarter made in a currency other than United States Dollars shall first be calculated in the foreign currency and then converted to United States Dollars on the basis of the average exchange rate in effect for such quarter for the purchase of United States Dollars with such foreign currency quoted in the Wall Street Journal (or comparable publication if not quoted in the Wall Street Journal) with respect to the currency of the country of origin of such payment, determined by averaging the rates so quoted on each business day of such quarter.

6.5 If, at any time, legal restrictions in the Territory prevent the prompt payment when due of royalties or any portion thereof, the Parties shall meet to discuss suitable and reasonable alternative methods of reimbursing Isis the amount of such royalties. In the event that Orasense is prevented from making any payment under this Agreement by virtue of the statutes, laws, codes or government regulations of the country from which the payment is to be made, then such payments may be paid by

depositing them in the currency in which they accrue to Isis's account in a bank acceptable to Isis in the country the currency of which is involved or as otherwise agreed by the Parties.

6.6 Isis and Orasense agree to co-operate in all respects necessary to take advantage of any double taxation agreements or similar agreements as may, from time to time, be available.

6.7 Any taxes payable by Isis on any payment made to Isis pursuant to this Agreement shall be for the account of Isis. If so required by applicable law, any payment made pursuant to this Agreement shall be made by Orasense after deduction of the appropriate withholding tax, in which event the Parties shall co-operate to obtain the appropriate tax clearance as soon as is practicable. On receipt of such clearance, Orasense shall forthwith procure that the amount so withheld is paid to Isis.

6.8 Orasense shall, not more than [***] in each calendar year, permit Isis or its duly authorized representatives upon reasonable notice and at any reasonable time during normal business hours to have access to inspect and audit the accounts and records of Orasense and any other book, record, voucher, receipt or invoice relating to the calculation of the royalty payments on Net Sales submitted to Isis. Any such inspection of Orasense's records shall be at the expense of Isis, except that if any such inspection reveals a deficiency in the amount of the royalty actually paid to Isis hereunder in any calendar quarter [***] or more of the amount of any royalty actually due to Isis hereunder, then the expense of such inspection shall be borne solely by Orasense. Any amount of deficiency shall be paid promptly to Isis by Orasense. If such inspection reveals a surplus in the amount of royalties actually paid to Isis by Orasense, Isis shall reimburse Orasense the surplus within fifteen (15) days after determination.

6.9 In the event of any unresolved dispute regarding any alleged deficiency or overpayment of royalty payments hereunder, the matter will be subject to resolution in accordance with Clause 24.9 of the Development Agreement, which is incorporated by reference and shall for such purposes survive termination of the Development Agreement.

9: INTELLECTUAL PROPERTY OWNERSHIP RIGHTS

9.1 Title and all other ownership rights, including patent rights, relating to the Isis Intellectual Property shall belong to Isis.

9.2 Each Party shall own the legal and equitable title to any invention invented by such Party that is not Orasense Intellectual Property.

9.3 Orasense shall permanently ▇▇▇▇ or otherwise use reasonable efforts to cause any third party to permanently ▇▇▇▇ all Products and/or the Packaging therefor with such license or patent notices to

comply with the applicable laws of each country of sale of the Territory or otherwise to generally communicate the existence of any of Patents under the Isis Intellectual Property for the countries of the Territory and in such manner as Isis may reasonably request in writing following receipt of written notice by Orasense of its intent to Commercialize a Product.

9.4 Isis, at its expense, shall (i) secure the grant of any material patent applications in the Territory to the Isis Delivery Technology that relate to the Field and the Isis Development Candidate Technology; (ii) defend all such applications against third party oppositions; and (iii) maintain in force any material issued letters patent within the Isis Delivery Technology that relate to the Field and the Isis Development Candidate Patents. Isis shall have the right in its discretion to control such filing, prosecution, defense and maintenance provided that Orasense and Elan at their request shall be provided with copies of all documents relating to such filing, prosecution, defense and maintenance in sufficient time to review such documents and comment thereon prior to filing.

9.5 In the event that Isis informs Orasense and Elan that it does not intend to file patent applications on patentable inventions and discoveries within the Isis Intellectual Property that relate to the Field in one or more countries in the Territory or fails to file such an application within a reasonable period of time, Orasense shall have the option at its expense to file and prosecute such patent application(s) in the joint names of Orasense and Isis. Upon written request from Orasense, Isis shall execute all documents, forms and declarations and to do all things as shall be reasonably necessary to enable Orasense to exercise such option.

9.6 Orasense, Isis and Elan shall promptly inform each other in writing of any alleged infringement of any patents within the Patents within the Isis Intellectual Property and the Orasense Intellectual Property or any alleged misappropriation of trade secrets within the Isis Intellectual Property or the Orasense Intellectual Property by a third party of which it becomes aware and provide the others with any available evidence of such infringement or misappropriation insofar as such infringements or misappropriation relate solely to the Field.

9.7 Orasense shall have the right to prosecute at its own expense and for its own benefit any infringements of the Patents within the Isis Intellectual Property or misappropriation of the Isis Intellectual Property, insofar as such infringements or misappropriation relate solely to the Field. In the event that Orasense takes such action, Orasense shall do so at its own cost and expense. At Orasense's request, Isis shall cooperate with such action. Any recovery in relation to such infringement proceeding shall belong to Orasense. Should Orasense decide not to pursue such infringers, within a reasonable period but in any event within [***] after receiving written notice of such alleged infringement or misappropriation Isis may in its discretion initiate such proceedings in its own name, at its expense and for its own benefit, and at Isis's request, Orasense shall cooperate with such action. Alternatively, Orasense and Isis may agree to institute such proceedings in their joint names and shall reach agreement as to the proportion in which they shall share the proceeds of any such proceedings, and the expense of any costs not recovered, or the costs or damages payable to the third party. If the infringement of the Patents within the Isis Intellectual Property affects both the Field as well as other products being developed or commercialized by Isis or its commercial partners outside the Field, Orasense and Isis shall endeavor to agree as to the manner in which the proceedings should be instituted and as to the proportion in which they shall share the proceeds of any such proceedings, and the expense of any costs not recovered, or the costs or damages payable to the third party.

During the Research Term and provided that Orasense is maintaining an active program for the development and Commercialization of the Development Candidate in the Field, Isis shall not develop or Commercialize or assist in the development for Commercialization [***] Nothing contained herein shall be construed as (i) limiting the activities of an existing third party licensee of Isis from developing Oligonucleotide Drugs utilizing Isis Delivery Technology to the extent such rights have been previously granted by Isis, provided Isis does not provide any active support to any such activities in excess of its existing contractual obligations or (ii) prohibiting Isis from licensing Isis Delivery Technology to an Independent Third Party or limiting the activities of any such future Independent Third Party licensee of Isis from developing [***] utilizing Isis Delivery Technology [***].

12: TERM AND TERMINATION OF AGREEMENT

12.1 The term of this Agreement and the term of the Isis License granted hereunder with respect to a Product utilizing or based on the Licensed Technologies shall commence as of the Effective Date and continue, on a Product-by-Product basis and country by country basis, for the life of the Patent rights upon which such Product is based on or utilizes in such country (the "Term"); provided, however, that all royalty and fee obligations contained herein shall survive for the greater of (i) the Term or (ii) [***] years from the first commercial sale of such Product.

12.2 Nothing contained herein shall obligate or restrict any party from utilizing public, non-proprietary information which is not subject to the protection of applicable patent laws.

12.3 If any Party breaches any material provision of this Agreement and if such breach is (i) not capable of being cured or (ii) is capable of being cured but is not corrected within [***] after the non-breaching Party gives written notice of the breach to the breaching Party, the non-breaching Party may terminate this Agreement immediately by giving notice of the termination to the breaching Party, effective on the date of the notice, provided, however, that (x) if any such curable breach is not capable of being cured within [***] period, so long as the breaching Party takes substantial steps to cure the breach promptly after receiving notice of the breach from the non-breaching party and thereafter diligently prosecutes the cure to completion as soon as is practicable, the non-breaching Party may not terminate this Agreement so long as the breaching party is acting in good faith to rectify such breach; provided, however, that, the completion of cure may not, in any event, exceed, [***] months from the date of receipt of notice by the breaching Party of its breach hereunder, or (y) the default involves a good faith dispute regarding the amount of any required payment, provided any undisputed amount is timely paid, such default shall be stayed and the remainder may be withheld for a reasonable period of time not to [***] days during which a good faith resolution of the amount owed is being pursued.

12.4 In the event that the Isis License Agreement shall be terminated, at the sole option of Elan and upon written notice to Isis and Orasense, the Elan License shall be immediately terminated.

12.5 In the event of an Failure to Fund, the Isis Development Candidate License will automatically terminate and all rights in the Isis Development Candidate Technology will revert back to Isis.

12.6 Upon the occurrence of an Event of Bankruptcy with respect to Orasense, Isis or Elan, the other Party may, upon written notice to Isis and the Party with respect to which such Event of Bankruptcy has occurred, immediately terminate the Elan License. As used in this Clause 12.5, the term "Event of Bankruptcy" relating to either Orasense or Elan shall mean:

12.6.1 the appointment of a liquidator, receiver, administrator, examiner, trustee or similar officer of either Party of it or over all or a substantial part of its assets under the law of any applicable jurisdiction, including without limit, Bermuda, the United States of America or Ireland; or

12.7 Upon exercise of those rights of termination as specified in Clause 12.1 to Clause 12.5 inclusive or elsewhere within this Agreement, this Agreement shall, subject to the other provisions of this Agreement, automatically terminate forthwith and be of no further legal force or effect.

12.8 Upon expiration or termination of the Agreement:

12.8.1 any sums that were due from Orasense to Isis under Clause 6, including without limitation on Net Sales, in the Territory or in such particular country or countries in the Territory (as the case may be) prior to the expiration or termination of this Agreement as set forth herein shall be paid in full within sixty (60) days after the expiration or termination of this Agreement for the Territory or for such particular country or countries in the Territory (as the case may be);

12.8.2 any provisions clearly meant to survive termination or expiration of this Agreement, including without limitation Clause 7, shall remain in full force and effect;

12.8.3 all representations, warranties and indemnities shall insofar as are appropriate remain in full force and effect;

12.8.4 the rights of inspection and audit set out in Clause 12.7 shall continue in force for a period of [***];

12.8.5 termination of this Agreement for any reason shall not release any Party hereto from any liability which, at the time of such termination, has already accrued to the other Party or which is attributable to a period prior to such termination nor preclude either Party from pursuing all rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement;

12.8.6 the Isis Intellectual Property and all rights, licenses and sublicenses granted by Isis in and pursuant to this Agreement shall cease for the Territory or for such particular country or countries in the Territory (as the case may be) and shall immediately revert to Isis. Following such expiration or termination, Orasense may not thereafter use in the Territory or in such particular country or countries in the Territory (as the case may be) (a) any valid and unexpired Patents in the Isis Intellectual Property and/or (b) any Isis Intellectual Property that remains confidential or otherwise proprietary to Isis. All rights to Orasense Intellectual Property will be transferred to and owned by Orasense. Rights of permitted Independent Third Party sublicensees in and to the Isis Intellectual Property shall survive the termination of the license and sublicense agreements granting said intellectual property rights to Orasense; and Orasense, Isis and Elan shall in good

faith agree upon the form most advantageous to Elan and Isis in which the rights of the sublicensor under any such sublicenses are to be held (which form may include continuation of Orasense solely as the holder of such licenses or assignment of such rights to a third party or parties, including an assignment to both Isis and Elan). Any sublicense agreement between Orasense and such permitted sublicensee shall permit an assignment of rights by Orasense to Isis and shall contain additional reasonable confidentiality protections which an assignee shall reasonably require. Upon any such assignment, Elan and Isis shall enter into good faith negotiations with respect to additional reasonable confidentiality protections which either party shall reasonably require.

13: FORCE MAJEURE

13.1 Neither Party to this Agreement shall be liable for delay in the performance of any of its obligations hereunder if such delay results from causes beyond its reasonable control, including, without limitation, acts of God, fires, strikes, acts of war, or intervention of a government authority, non availability of raw materials, but any such delay or failure shall be remedied by such Party as soon as practicable; provided, however, that neither party hereunder shall be excused for delay in the performance of any of its payment obligations hereunder.

14: SETTLEMENT OF DISPUTES; GOVERNING LAW

14.1 Any dispute between the Parties arising out of or relating to this Agreement will be subject to resolution in accordance with Clause 24.9 of the Development Agreement, which is incorporated by reference and shall for such purposes survive termination of the Development Agreement.

14.2 This Agreement is construed under and ruled by the laws of the State of New York, without regard to the conflict of law principles.

15: ASSIGNMENT

This Agreement may not be assigned by either Party without the prior written consent of the other, which consent shall not be unreasonably withheld, conditioned or delayed, save that (i) either Party may assign this Agreement to its Affiliate without such consent, provided that such assignment does not have any adverse tax consequences on the other Party, and (ii) Isis may assign its rights and obligations hereunder in connection with a sale of its business or sale of any of the Isis Intellectual Property licensed hereunder, whether by merger, sale of stock, sale of assets or otherwise. Isis, Elan and Orasense will discuss any assignment by either Party to an Affiliate prior to its implementation in order to avoid or reduce any additional tax liability to the other Party resulting solely from different tax law provisions applying after such assignment to an Affiliate. For the purpose hereof, an additional tax liability shall be deemed to have occurred if either Party would be subject to a higher net tax on payments made hereunder after taking into account any applicable tax treaty and available tax credits than such Party was subject to before the proposed assignment. Notwithstanding any assignment hereof to an Affiliate, each Party will remain fully liable hereunder.
