 (b) Whenever any payment hereunder shall be stated to be due on a day which is not a Business Day, such
payment shall be made on the immediately succeeding Business Day. 
 (c) Payments hereunder shall be considered to be made as of the date on

firm of nationally recognized standing selected by Unigene and reasonably acceptable to USL, at Unigene’s expense, to have access during normal business hours to examine books and records of USL described in Section 6.1 hereof as may be
reasonably necessary to verify the accuracy of the reports described in Section 6.2 hereof. The examination shall be limited to USL’s books and records for any year ending not more than *** (***) months prior to the date of such request,
unless any such audit establishes that the Royalties actually paid for any Market Year subject to the audit were actually less than *** percent (***%) of the Royalties due for such Market Year, in which event the audit may extend to include records
ending not more than *** (***) months prior to the date of such initial request. An examination under this Section 6.4 shall not occur more than once in any Market Year, and any period shall be subject to audit under this Section 6.4 only

to examine the relevant books and records or to report the accountant’s conclusions to Unigene. The accounting firm shall disclose to Unigene only whether the reports described in Section 6.2 hereof are correct or incorrect and the
specific details concerning any discrepancies. Any such accounting firm shall sign a confidentiality agreement, in a form and substance reasonably acceptable to USL, as to any of USL’s confidential information which they are provided or to
which they have access while conducting any audit pursuant to this Section 6.4. Unigene shall pay all costs of conducting audits pursuant to this Section 6.4; provided, however, that USL shall reimburse Unigene in full for
such reasonable costs whenever the accounting reveals that, with respect to any audited period (but in no event a period of less than a Market Year), the aggregate Royalties actually paid to Unigene were less than *** percent (***%) of the total of
Royalties due to Unigene hereunder. Should such an audit identify an underpayment of aggregate Royalties, USL shall immediately remit such underpayment amount to Unigene plus interest at the bank reference rate of TCF Bank Minnesota from the date
the payment should have been made. Should such an audit identify any overpayment of aggregate Royalties, Unigene shall immediately remit such overpayment amount to USL, ***.

 ARTICLE 7. PRODUCTION, TESTING, FORECASTING 
 7.1. Production. 
 (a) Except as provided in
Sections 7.3 and 2.5, Unigene shall produce API for Product, formulate Product, fill, label and bulk package the Vials with Product for supply to USL, and USL shall obtain Product in Vials from Unigene. Unigene shall collect such data on production,
maintain such records, retain such retention and reserve samples of all raw materials and in-process production steps, and take such other steps as required to comply with cGMP. Subject to the confidentiality provisions set forth in ARTICLE 15
hereof, Unigene and USL shall both share such data, information or samples with one another as required to maintain the NDA. Unigene will have, during the period it is to supply Vials or API to USL under this Agreement, the requisite experience,
knowledge and expertise, suitable facility and qualified personnel, as well as the legal right, to perform its obligations under this Agreement in a sound, safe, lawful and workmanlike manner. In addition, Unigene will perform in accordance with the
terms of Exhibit B attached hereto. USL has the requisite experience, knowledge and expertise, suitable facility and qualified personnel, as well as the legal right to perform its obligations under this Agreement in a sound, safe, lawful and
workmanlike manner. 
 (b) Unigene shall supply all of USL’s requirements for Vials as stated in USL’s purchase orders as described
below, provided, however, that Unigene shall not be obligated to accept purchase orders for more than *** Vials per Market Year (the “Annual Volume Cap”) or purchase orders for the delivery of more than ***
Vials in any calendar month (the “Monthly Volume Cap”). 
 (c) USL shall purchase the pumps to be included in
Finished Product from a Third Party, and provide appropriate samples to Unigene at no cost. Unigene shall, thereafter, test and release the pumps from such sample. 
  

 - 15 - 







 7.2. Forecasting; Purchase Orders. 
 (a) USL will deliver to Unigene, within seven (7) days after the beginning of each USL manufacturing quarter, its forecast for Vials for the
succeeding twelve (12) manufacturing month period (the “Forecast”), provided that the first Forecast will be provided approximately six (6) months prior to the anticipated date of commercial launch of the Finished
Product. The Forecast will be updated each manufacturing quarter on a rolling twelve (12) month basis. Unigene will use the Forecast for planning purposes only. For any given quarter, Unigene may purchase raw materials and components (for Vials
or API, as applicable) on the basis of USL’s most recent Forecast for Vials or API (as applicable) for the second manufacturing quarter covered by that Forecast given in accordance with this Section 7.2(a). If USL does not submit purchase
orders for that manufacturing quarter in a volume equaling or exceeding such Forecast for that quarter, USL will reimburse Unigene for the cost of those raw materials and components that Unigene cannot use thereafter for the manufacture of Product
or Vials or otherwise for equivalent value. 
 (b) Vials will be ordered by USL by the issuance of separate, pre-numbered binding purchase
orders. Unigene will supply USL with its estimated batch yield of Vials to assist USL in ordering batch lot quantities. USL’s purchase orders will designate the desired quantities of the Vials, delivery dates and destinations and will be
submitted at least *** (***) days prior to the shipment date specified. Subject to the terms of Section 7.1(b) above, Unigene will fill and ship all orders of Vials in accordance with USL’s purchase orders provided that if such orders
exceed the Forecast for such period by more than *** percent (***%), Unigene shall not be required to fill and ship such excess amount, but shall use commercially reasonable efforts to do so. If any USL purchase order is not submitted at least ***
(***) days prior to the requested delivery dates, Unigene will still use commercially reasonable efforts to meet USL’s requested delivery dates. Unigene shall not produce Vials more than *** (***) days prior to the shipment date of such Vials;
provided, however, in the event that the FDA approves the Product for *** (***) month expiration dating, Unigene shall not produce Vials more than *** (***) days, rather than the aforementioned *** days, prior to the shipment date of
such Vials. 
 (c) All sales of Vials by Unigene to USL will be subject to the provisions of this Agreement and will not be subject to the
terms and conditions contained in any purchase order of USL or confirmation of Unigene, except insofar as any such purchase order or confirmation establishes (i) the quantity of Vials to be sold; (ii) the shipment dates for those Vials;
and (iii) the destinations to which those Vials are to be shipped. In the event of any conflict between the terms of this Agreement and the terms of any purchase order, invoice or similar document, the terms of this Agreement shall prevail.

 7.3. Alternative Source for Vials.  
 (a) Unigene must be able to supply Vials sufficient to meet the Monthly Volume Cap and the Annual Volume Cap. In order to do so, Unigene shall have the
right to designate and (at Unigene’s expense) qualify a Third Party to supply Vials;***. 
 (b) In addition, if USL anticipates
that it will require a quantity of Vials in excess of the Monthly Volume Cap and/or the Annual Volume Cap, USL shall give Unigene reasonable notice thereof. USL and Unigene shall thereafter promptly meet and work together in good faith to identify a
reasonable means of increasing capacity for supply in a mutually beneficial, commercially reasonable manner, with the objective of having excess capacity available in the time period reasonably requested by USL. Alternatives for doing so may include
Unigene increasing its capacity, qualifying a Third Party to supply Vials, qualifying USL to supply Vials (in which case USL may manufacture Product and Vials under the license and right granted in Sections 2.1(b) and 2.2(b) above and Unigene shall
supply all of USL’s requirements for API for use in the manufacture of such Product and Vials (and USL will furnish forecasts and purchase orders for API in the same manner as contemplated in Section 7.2 for Vials)), or some combination
thereof, with the objective of achieving such extra capacity in the reasonable time frame on commercially reasonable terms. USL and Unigene shall agree in good faith upon a commercially reasonable manner to proceed with a view of time frame, cost
and other commercially reasonable considerations. All costs and expenses incurred in connection with Unigene increasing its capacity, qualifying a Third Party to supply Vials, qualifying USL to supply Vials, or some combination thereof, pursuant to
this Section 7.3(b), shall be borne *** by USL and *** by Unigene. Notwithstanding anything in this Section 7.3(b) to the contrary, upon USL giving notice that it will require a quantity of Vials in excess of the Monthly Volume Cap and/or
the Annual Volume Cap, Unigene and USL will within *** (***) days of such notice meet to commence good faith discussions and negotiations to decide among the three alternatives taking into account commercially reasonable considerations as discussed
in this Section 7.3(b); provided, however, that if USL and Unigene cannot reach agreement with respect thereto within *** (***) days following USL’s written notice, (i) the respective officers of Unigene and USL with
decision making authority with respect to such matter shall meet face-to-face within *** (***) days after the expiration of the aforementioned *** (***) day period, and (ii) if the respective officers of Unigene and USL cannot resolve the
matter within *** (***) days after their first meeting, the matter shall be submitted to arbitration pursuant to Section 17.2. 
 7.4.
Transfer Price. 
 (a) The “Transfer Price” shall initially be *** per Vial (plus transportation charges, including
insurance). If it becomes clear that by reason of costs outside Unigene’s control that Unigene’s *** percent (***%) shall exceed the *** (plus transportation charges, including insurance) by *** percent (***%) or more, Unigene shall
deliver USL written notice of the same (including an explanation of the cause of the increase to Unigene’s ***) at least thirty (30) days before the end of the relevant Reporting Quarter, along with a revised Transfer Price calculated to
achieve a price equal to Unigene’s *** percent (***%) based on prices available at the time of the notice, provided that in no event shall the Transfer Price change more than once annually. Notwithstanding the foregoing, at such time as
USL’s obligation for the payment of Earned Royalties expires under Section 4.2(a), the applicable Transfer 

  

 - 17 - 







 
Price shall be increased to an amount equal to Unigene’s *** percent (***%). In the event USL commences manufacture of Product and Vials pursuant to
Section 7.3 or Section 2.5, the Transfer Price for API supplied by Unigene to USL hereunder shall equal Unigene’s *** percent (***%) until such time as USL’s obligation for the payment of Earned Royalties expires under
Section 4.2(a), and thereafter the applicable Transfer Price for API shall be increased to an amount equal to Unigene’s *** percent (***%), subject to the terms of Section 14.1(b) below. 
 (b) After the Transfer Price increases to Unigene’s ***, Unigene shall, upon written request from USL from time to time, but not more than once in
any Market Year, promptly furnish to USL written documentation maintained by Unigene in the ordinary course evidencing the cost of ***. Upon thirty (30) days prior written notice to Unigene, Unigene shall permit an independent certified public
accounting firm of nationally recognized standing selected by USL and reasonably acceptable to Unigene, at USL’s expense, to have access during normal business hours to examine books and records of Unigene hereof as may be reasonably necessary
to verify the accuracy of the Transfer Price for any period after USL’s obligation for the payment of Earned Royalties expires under Section 4.2(a), and written documentation evidencing the cost of manufacture described in this
Section7.4(b). The examination shall be limited to Unigene’s books and records for any year ending not more than *** (***) months prior to the date of such request, unless any such audit establishes that the Transfer Price actually paid for any
Market Year subject to the audit were actually more than *** percent (***%) of the Royalties due for such Market Year after USL’s obligation for the payment of Earned Royalties expires under Section 4.2(a), in which event the audit may
extend to include records ending not more than *** (***) months prior to the date of such initial request. An examination under this Section 7.4(b) shall not occur more than ***, and any period shall be subject to audit under this
Section 7.4(b) only once during the term of this Agreement. Unigene may designate competitively sensitive information, which such accountant may not disclose to USL, provided, however, that such designation shall not impair the
accountant’s ability to examine the relevant books and records or to report the accountant’s conclusions to USL. The accounting firm shall disclose to USL only whether the Transfer Price paid for the period subject to the audit are correct
or incorrect and the specific details concerning any discrepancies. Any such accounting firm shall sign a confidentiality agreement, in a form and substance reasonably acceptable to Unigene, as to any of Unigene’s confidential information which
they are provided or to which they have access while conducting any audit pursuant to this Section 7.4(b). USL shall pay all costs of conducting audits pursuant to this Section 7.4(b); provided, however, that Unigene shall
reimburse USL in full for such reasonable costs whenever the accounting reveals that, with respect to any audited period (but in no event a period of less than a Market Year), the aggregate Transfer Price actually paid by USL was more than ***
percent (***%) of the total Transfer Price due to Unigene for the applicable period hereunder. Should such an audit identify an overpayment of Transfer Price for any period after USL’s obligation for the payment of Earned Royalties expires
under Section 4.2(a), Unigene shall immediately remit such overpayment amount to USL plus interest at the bank reference rate of TCF Bank Minnesota from the date the overpayment was made. Should such an audit identify any underpayment of
Transfer Price for any period after USL’s obligation for the payment of Earned Royalties expires under 

  

 - 18 - 







 
Section 4.2(a), USL shall immediately remit such underpayment amount to Unigene, plus interest at the bank reference rate of TCF Bank Minnesota from the
date the payment should have been made. 
 (c) For each Vial or API (as the case may be) shipped to USL, USL shall pay to Unigene the
Transfer Price, which shall be due and payable within thirty (30) days after the last to occur of (i) delivery to USL’s facility of the applicable shipment of Vials or API (as the case may be); and (ii) the delivery to USL of the
invoice relating to the applicable shipment of Vials or API (as the case may be). 
 (d) For each Reporting Quarter, the aggregate amount of
any accumulated Transfer Price paid to Unigene, except for such amounts paid on Vials or API (as the case may be) used in samples distributed for no cost or a nominal cost (“Free Samples”), shall be creditable against Earned
Royalties pursuant to Section 4.3. 
 7.5. Shipment and Risk of Loss. Unigene will ship all Vials or API (as the case may be) to USL,
F.O.B. point of delivery (USL’s loading dock). The risk of loss of or damage to any Vials or API (as the case may be) ordered by USL and shipped by Unigene will pass to USL upon Unigene’s delivery to USL, F.O.B. point of delivery
(USL’s loading dock). Unigene will pay the cost of all freight and insurance for each shipment.

injuries, losses, costs and expenses (including reasonable attorney’s fees and disbursements) arising from or claimed to arise from the manufacture of Vials (but only in the event and to the extent that USL manufactures Vials), assembly, outer
packaging, labeling, transportation of Finished Product from USL’s facility, sale, performance or use of Finished Product by USL. Notwithstanding the foregoing provisions of this Section 12.2(b), in no event will an Indemnitee be entitled
to indemnification under this Section 12.2(b) with respect to any and all losses, liabilities, claims, costs, damages and expenses (including, without limitation, fines, forfeitures, reasonable attorneys’ fees, disbursements and
administrative or court costs) to the extent that they arise from an Indemnitee’s (including any Affiliates of an Indemnitee) negligence or willful misconduct. 
 12.3. Procedure. A Party (the “Indemnitee”) that intends to claim indemnification under this Article 9 shall promptly notify the other Party (the “Indemnitor”) in writing of any loss, claim,
damage, liability or action in respect of which the Indemnitee or any of its Affiliates, sublicensees or their directors, officers, employees, agents or counsel intend to claim such indemnification, and the Indemnitor shall have the right to
participate in, and, to the extent the Indemnitor so desires, to assume the defense thereof with counsel mutually satisfactory to the Parties. The indemnity agreement in this Article 9 shall not apply to amounts paid in settlement of any loss,
claim, damage, liability or action if such settlement is made without the consent of the Indemnitor, which consent shall not 

  

 - 24 - 







 
be withheld unreasonably. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such action, if
prejudicial to its ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Article 9. At the Indemnitor’s request, the Indemnitee under this Article 9, and its employees and agents, shall
cooperate fully with the Indemnitor and its legal representatives in the investigation and defense of any action, claim or liability covered by this indemnification and provide full information with respect thereto. 
 12.4. Insurance. From and after NDA Approval, each party will at all times thereafter during the term of this Agreement, maintain in full force and
effect, for the benefit of itself and each other, comprehensive general liability insurance which (i) is sufficient to protect against the risks associated with its ongoing business, including the risks which might possibly arise in connection
with the transactions contemplated by this Agreement and in any event, will maintain product liability insurance in an amount not less than *** for each occurrence and in the aggregate; and (ii) that cannot be terminated or canceled without
giving the other party thirty (30) days prior written notice. Each party’s product liability insurance policy will name the other party as an additional insured. Upon request of the other party, each party shall furnish the other with a
certificate of insurance evidencing that such insurance coverage is in force. 
 12.5. Finished Product Recalls. In the event (i) the
FDA issues a request, directive or order that any Finished Product be recalled; or (ii) a court of competent jurisdiction orders such a recall; or (iii) Unigene reasonably determines, after consultation with USL, that any Finished Product
should be recalled because API, Product or Vials do not conform to Specifications; or (iv) USL, after consultation with Unigene, reasonably determines that any Finished Product should be recalled for any reason, the parties will take all
appropriate corrective actions reasonably requested by the other party or by the FDA. To the extent that any such recall results because API, Product or Vials (in each case made by or on behalf of Unigene) do not conform to Specifications, Unigene
will be responsible for all of the expenses of the recall. In all other cases, USL will be responsible for all of the expenses of the recall. For the purposes of this Agreement, the expenses of the recall will include, without limitation, all
expenses for notification of customers and the destruction or return of the recalled Finished Product, as well as all reasonable out-of-pocket costs incurred by Unigene and USL in connection with any corrective action taken by Unigene and USL. USL
will conduct the recall process. USL and Unigene will fully cooperate with the other party to assist in the recall process as reasonably necessary to complete the process.

price and terms on which Unigene *** for supply to USL hereunder, or (3) the price and terms on which Unigene *** for the production of Product and Vials, in the event that USL

 ARTICLE 16. TERM

the other, which consent will not be unreasonably withheld.

assign its rights hereunder to an Affiliate or, subject to the terms of this Section 17.1, to a purchaser in connection with a merger or consolidation of such party, or a sale of all or substantially all of the assets or business of that party
to which the Product relates (in each case, outside of a bankruptcy proceeding in which USL is the bankrupt party). 
 (c) If USL is the
assignor and the assignee is *** or another party engaged in the business of marketing or selling a *** product, such assignment of this Agreement by USL shall be subject to the prior written approval of Unigene. USL shall give prior written notice
of the anticipated assignment to such a party, and within *** (***) days after Unigene’s receipt of USL’s notice, Unigene shall give USL written notice whether it approves or does not approve of such an assignment. If Unigene fails to give

*** product that is not a *** product, then USL shall give prior written notice of the anticipated assignment to such a party, and within *** (***) days after Unigene’s receipt of USL’s notice, Unigene shall notify USL either (1) that
Unigene elects to permit the assignment of *** the assignment of this Agreement to such assignee, or alternatively (2) that Unigene elects, at the time of the assignment of this Agreement to such assignee, ***, and contemporaneously to grant
such assignee all rights, and deliver such documents and do such things, ***, as reasonably required to permit USL to provide the assignee all rights to commercialize the Finished Product as provided to USL under this Agreement (it being the
intention of the parties that such *** shall not present an impediment in any respect to the assignee’s ability to commercialize the Finished Product or otherwise to exercise the rights under this Agreement). If Unigene fails to give written
notice of its election under the preceding sentence within the specified time frame, Unigene shall be deemed to have elected to permit the *** to such assignee. 
  


 - 35 - 







 (e) Any assignment of this Agreement by either Unigene or USL shall not release the assigning party
hereto from its duties and obligations under this Agreement, and in the event of any such assignment of this Agreement the assignee must agree in writing to be bound by the terms and conditions of this Agreement. Any purported assignment,
delegation, sale, transfer or other disposition in violation of this Section 17.1 shall be null and void. This Agreement shall be binding upon, and inure to the benefit of, Unigene and USL and their respective successors and assigns, to the
extent such assignments are in accordance with this Section 17.1. 
 17.2 Governing Law. This Agreement shall be governed by the
substantive laws of the State of New York (without regard to the principles regarding conflicts of law). All disputes arising out of or relating to this Agreement (including any questions of fraud or questions concerning the validity or
enforceability of this Agreement) shall, unless earlier resolved by mutual agreement, be finally settled by arbitration to be held in Chicago, Illinois pursuant to the then existing Commercial Rules of the American Arbitration Association. The
arbitration panel shall consist of three arbitrators. Each party shall appoint one arbitrator within thirty (30) days from the date of filing any demand for arbitration and the third arbitrator (as well as any other vacancies on the panel)
shall be appointed by the American Arbitration Association. The arbitration hearing will take place and the award will be made within ninety (90) days of the filing of any demand for arbitration. Any determination as to the arbitrability of an
issue or dispute shall be made by the arbitrators. Judgment upon the award of a majority of the arbitrators shall be binding upon the parties hereto and may be entered in any court having jurisdiction. Specific performance and injunctive relief may
be ordered by the award. The parties shall each pay their respective costs and attorney fees. The fees and costs to be paid to the AAA for the arbitration shall be allocated between Unigene and USL so that (a) the party initiating arbitration
(the “Initiating Party”) shall pay a portion of the arbitration fees and costs to be paid to the AAA proportionate to the aggregate amount of the disputed items submitted to arbitration that are decided against the Initiating Party
relative to the total amount of all disputed items submitted to arbitration, and (b) the non-Initiating Party shall pay the balance. In the event that a dollar value cannot be assigned to a matter taken to arbitration, the arbitration expenses
shall be allocated between Unigene and USL in accordance with the decision of the arbitration panel that reflects the relative fault of the parties. As the sole exception to arbitration, each party shall have the right to obtain injunctive relief
from any court having jurisdiction so as to preserve that party’s rights for resolution in any pending or imminent arbitration proceedings, but no such injunction shall prohibit or postpone such arbitration proceedings and the injunctions may
be modified or vacated as a result of the arbitration award.

 2. Grant of Security. As security for the due and punctual performance of the Obligations, the Company hereby grants to the Secured Party a security interest in
the Collateral. 
 3. Release and Satisfaction. Upon the termination of this Agreement, the Secured Party shall promptly deliver to the Company upon
request therefor and at the Company’s expense, releases and satisfactions of all registrations of the security interests granted hereunder. 
 4.
Representations and Warranties. The Company hereby represents and warrants to the Secured Party that, as of the date hereof: 
 4.1. The
Company owns all of the Collateral free and clear of any lien, encumbrance, mortgage, security agreement, pledge or charge other than a license agreement, dated as of July 15, 1997, between the Company and Warner-Lambert Company, pursuant to
which the Company has licensed to Warner-Lambert Company the right to use United States patent No. 5,912,014 
 4.2. The Company is a
corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority to carry on its business and own its properties as now conducted and owned. The Company
is duly qualified to do business as a foreign corporation and in good standing in the State of New Jersey.

corporate power and authority to execute, deliver and perform this Agreement and has taken all requisite corporate action necessary for (i) the authorization, execution and delivery of this Agreement and (ii) the performance of all 







 
obligations of the Company hereunder. This Agreement constitutes the legal, valid and binding obligation of the Company, enforceable against the Company in
accordance with its terms except as such enforcement may be limited by (a) applicable bankruptcy, insolvency, reorganization, voidable preference, fraudulent conveyance and other similar laws affecting the rights or remedies of creditors

attorney-in-fact with full power and authority and in the place and stead of the Company and in the name of the Company or in his own name, from time to time, in the Secured Party’s discretion, for the purpose upon the occurrence of an Event of
Default of executing and filing such assignment of the Collateral, and executing on behalf and in the name of the Company any and all instruments and documents and to take any and all appropriate action in furtherance of the foregoing. 

9. Use of Income. Until the occurrence of an Event of Default, the Company reserves the right to receive all income and royalties from the Collateral.

 10. Termination. This Agreement shall terminate at such time as all of the Obligations shall have been indefeasibly fully paid and satisfied and,
until such time, the Secured Party shall retain all security in the Collateral held by it hereunder. 
 11. Binding Effect. This Agreement shall be
binding upon the Company and its successors and assigns and shall inure to the benefit of the Secured Party and his heirs, executors, administrators, successors and assigns. 
 12. Notices. Unless otherwise provided, any notice required or permitted under this Agreement shall be given in writing and shall be deemed effectively given (i) on the same day if given by personal

 or at such other address as such
party may designate by ten days’ advance written notice given hereunder to any other party. 
 13. Waiver. No delay or failure on the part of the
Secured Party in exercising any right, privilege, remedy or option hereunder shall operate as a waiver of such or any other right, privilege, remedy or option, and no waiver shall be valid unless in writing and signed by the Secured Party and then
only to the extent therein set forth.

interest in the Collateral (as hereinafter defined) to secure payment by the Company of the Obligations (as hereinafter defined); and 
 NOW,
THEREFORE, in consideration of the premises, the mutual promises made herein and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

 1.1 “Collateral” shall mean (i) the United States patents identified on Exhibit A hereto, (ii) the United States patent
applications identified on Exhibit A hereto and any and all patents that issue with respect thereto, (iii) all renewals thereof, (iv) all income, royalties, damages and payments now and hereafter due and/or payable under and with
respect thereto, including, without limitation, payments under all licenses entered into in connection therewith and damages and payments for past or future infringements thereof, (v) the right to sue for past, present and future infringements

 1.3 “Obligations” shall mean all indebtedness, obligations and liabilities of every kind and nature of the Company now or hereafter existing
under or arising out of or in connection with the New Note, all Future Notes (if any), and this Agreement and all extensions, amendments or renewals hereof or thereof, whether for principal, premium, interest, or fees, and all or any portion of such
indebtedness, obligations or liabilities that are paid to the extent all or any part of such payment is avoided or recovered directly or indirectly from the Secured Party as a preference, fraudulent transfer or otherwise. 
 2. Grant of Security. As security for the due and punctual performance of the Obligations, the Company hereby grants to the Secured Party a security interest in
the Collateral. 
 3. Release and Satisfaction. Upon the termination of this Agreement, the Secured Party shall promptly deliver to the Company upon
request therefor and at the Company’s expense, releases and satisfactions of all registrations of the security interests granted hereunder. 
 4.
Representations and Warranties. The Company hereby represents and warrants to the Secured Party that, as of the date hereof: 
 4.1. The
Company owns all of the Collateral free and clear of any lien, encumbrance, mortgage, security agreement, pledge or charge other than a license agreement, dated as of July 15, 1997, between the Company and Warner-Lambert Company, pursuant to
which the Company has licensed to Warner-Lambert Company the right to use United States patent No. 5,912,014 
 4.2. The Company is a
corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority to carry on its business and own its properties as now conducted and owned. The Company
is duly qualified to do business as a foreign corporation and in good standing in the State of New Jersey. 
 4.3. The Company has full
corporate power and authority to execute, deliver and perform this Agreement and has taken all requisite corporate action necessary for (i) the authorization, execution and delivery of this Agreement and (ii) the performance of all
obligations of the Company hereunder. This Agreement constitutes the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms except as such enforcement may be limited by (a) applicable
bankruptcy, insolvency, reorganization, voidable preference, fraudulent conveyance and other similar laws affecting the rights or remedies of creditors generally and (b) the exercise of judicial discretion in accordance with general principles
of equity (whether applied by a court of law or equity). 






 5. Further Actions. The Company agrees that from time to time, at the expense of the Company, the Company will
promptly execute and deliver all further instruments and documents and take all further action that the Secured Party reasonably may request in order to perfect the security interest granted hereby, including the execution, recording and filing of

 (a) not use or permit any Collateral to be

 (b) pay all applicable maintenance fees and other statutory fees due and payable with respect to the Collateral; 
 (c) take all actions reasonably necessary to defend the validity of the Collateral; 
 (d) use its best efforts to maintain in full
force and effect the Collateral; 
 (e) pay promptly when due all property and other taxes, assessments and governmental charges or levies
imposed upon, and all claims against, the Collateral, except to the extent the validity thereof is being contested in good faith; 
 (f) not
sell, assign (by operation of law or otherwise) or otherwise dispose of any of the Collateral, except (i) as permitted by this Agreement and (ii) that the Company may dispose of Collateral that has become obsolete; 
 (g) keep reasonable records respecting the Collateral and at all times keep at least one complete set of its records concerning all of the Collateral at

 (h) not enter into any agreement, including, without limitation, any
license agreement, inconsistent with this Agreement without the Secured Party’s prior written consent. 
 7. Secured Party May Perform. If the
Company fails to perform any agreement contained herein, the Secured Party may itself perform, or cause performance of, such agreement, and the expenses of the Secured Party incurred in connection therewith shall be reimbursed by the Company
promptly. 
 8. Enforcement. Upon the occurrence of an Event of Default, the Secured Party shall have all the rights, privileges, powers and remedies
of a secured party under the Uniform Commercial Code and all other applicable laws and such additional rights as are set 







 
forth herein. In addition to any other rights and remedies the Secured Party may have, the Secured Party may file and record with the United States Patent
and Trademark Office an absolute assignment (as opposed to a collateral assignment) of the Collateral to the Secured Party. Upon such assignment, the Secured Party may sell, retain, or otherwise dispose of the Collateral in the same manner as any
other property of the Company which constitutes security for the Obligations. In addition, the Company hereby irrevocably constitutes and appoints the Secured Party (which appointment is coupled with an interest) as its true and lawful
attorney-in-fact with full power and authority and in the place and stead of the Company and in the name of the Company or in his own name, from time to time, in the Secured Party’s discretion, for the purpose upon the occurrence of an Event of
Default of executing and filing such assignment of the Collateral, and executing on behalf and in the name of the Company any and all instruments and documents and to take any and all appropriate action in furtherance of the foregoing. 

9. Use of Income. Until the occurrence of an Event of Default, the Company reserves the right to receive all income and royalties from the Collateral.

 10. Termination. This Agreement shall terminate at such time as all of the Obligations shall have been indefeasibly fully paid and satisfied and,
until such time, the Secured Party shall retain all security in the Collateral held by it hereunder. 
 11. Binding Effect. This Agreement shall be
binding upon the Company and its successors and assigns and shall inure to the benefit of the Secured Party and his heirs, executors, administrators, successors and assigns. 
 12. Notices. Unless otherwise provided, any notice required or permitted under this Agreement shall be given in writing and shall be deemed effectively given (i) on the same day if given by personal
delivery, (ii) on the following business day if given by telecopier with confirmation of receipt, or (iii) on the following business day if given by nationally recognized overnight air courier, in each case addressed to the party to be

 or at such other address as such
party may designate by ten days’ advance written notice given hereunder to any other party.
