The inclusion of Proceeds in the Collateral shall not be deemed to constitute Agent’s consent to any sale or other disposition of any of the Collateral except as expressly permitted in this Agreement or the other Note Documents;

(k) Other Actions as to Any and All Collateral. Grantor shall promptly (and in any event within 5 Business Days of acquiring or obtaining such Collateral) notify Agent in writing upon (i) acquiring or otherwise obtaining any Collateral after the date hereof consisting of Trademarks, Patents, Copyrights, Intellectual Property Licenses, Investment Related Property, Chattel Paper (electronic, tangible or otherwise), Real Property, documents (as defined in Article 9 of the Code), promissory notes (as defined in the Code, or instruments (as defined in the Code) or (ii) any amount payable under or in connection with any of the Collateral being or becoming evidenced after the date hereof by any Chattel Paper, documents, promissory notes, or instruments, in each case with a value in excess of $10,000 individually and $25,000 in the aggregate and, in each such case upon the request of Agent, promptly execute such other documents, or if applicable, deliver such Chattel Paper, other documents or certificates evidencing any Investment Related Property and do such other acts or things deemed necessary or desirable by Agent to protect Agent’s Security Interest therein;

(l) Changes in Locations, Names, etc. Grantor shall not, except upon prior written consent of Agent and delivery to Agent of additional financing statements and other documents reasonably requested by Agent as to the validity, perfection and priority of the Security Interests provided herein, change its name, identity, corporate structure or jurisdiction of organization; and

(m) Notices. Grantor will advise Agent promptly, in reasonable detail, of: (i) any Lien (other than Permitted Liens) on any of the Collateral which would adversely affect

the ability of Agent to exercise any of its remedies hereunder and (ii) the occurrence of any other event which could reasonably be expected to have a material adverse effect on the aggregate value of the Collateral.

7. Relation to Other Security Documents. The provisions of this Agreement shall be read and construed with the provisions of the Patent Security Agreements, which are supplemental to the provisions of this Agreement. Nothing contained in the Patent Security Agreements shall limit any of the rights or remedies of Agent hereunder.

8. Further Assurances.

(a) Grantor agrees that from time to time, at its own expense, Grantor will promptly execute and deliver all further instruments and documents, and take all further action, that may be necessary or that Agent may reasonably request, in order to perfect and protect the Security Interest granted or purported to be granted hereby or to enable Agent to exercise and enforce its rights and remedies hereunder with respect to any of the Collateral.

(b) Grantor authorizes the filing by Agent of financing or continuation statements, or amendments thereto, and Grantor will execute and deliver to Agent such other instruments or notices, as may be necessary or as Agent may reasonably request, in order to perfect and preserve the Security Interest granted or purported to be granted hereby.

(c) Grantor authorizes Agent at any time and from time to time to file, transmit, or communicate, as applicable, financing statements and amendments (i) describing the Collateral as “all personal property of debtor” or “all assets of debtor” or words of similar effect, (ii) describing the Collateral as being of equal or lesser scope or with greater detail, or (iii) that contain any information required by part 5 of Article 9 of the Code for the sufficiency or filing office acceptance. Grantor also hereby ratifies any and all financing statements or amendments previously filed by Agent in any jurisdiction.

(d) Grantor acknowledges that it is not authorized to file any financing statement or amendment or termination statement with respect to any financing statement filed in connection with this Agreement without the prior written consent of Agent, subject to Grantor’s rights under Section 9-509(d)(2) of the Code.

9. Agent’s Right to Perform Contracts, Exercise Rights, etc. Upon the occurrence and during the continuance of an Event of Default, Agent (or its designee) (a) may proceed to perform any and all of the obligations of Grantor contained in any contract, lease, or other agreement and exercise any and all rights of Grantor therein contained as fully as Grantor itself could, (b) shall have the right to use Grantor’s rights under Intellectual Property Licenses in connection with the enforcement of the Agent’s rights hereunder, including the right to prepare for sale and sell any and all Inventory and Equipment now or hereafter owned by Grantor and now or hereafter covered by such licenses, and (c) shall have the right to request that any Stock that is pledged hereunder be registered in the name of Agent or any of its nominees.

10. Agent Appointed Attorney-in-Fact. Grantor hereby irrevocably appoints Agent its attorney-in-fact, with full authority in the place and stead of Grantor and in the name of Grantor or otherwise, at such time as an Event of Default has occurred and is continuing under the Notes,

to take any action and to execute any instrument which Agent may reasonably deem necessary or advisable to accomplish the purposes of this Agreement, including:

(a) to ask, demand, collect, xxx for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in connection with the Accounts or any other Collateral of Grantor;

(b) to receive and open all mail addressed to Grantor and to notify postal authorities to change the address for the delivery of mail to Grantor to that of Agent;

(d) to file any claims or take any action or institute any proceedings which Agent may deem necessary or desirable for the collection of any of the Collateral of Grantor or otherwise to enforce the rights of Agent with respect to any of the Collateral;

(e) to repair, alter, or supply goods, if any, necessary to fulfill in whole or in part the purchase order of any Person obligated to Grantor in respect of any Account of Grantor;

(f) to use any labels, Patents, Trademarks, trade names, URLs, domain names, industrial designs, Copyrights, advertising matter or other industrial or intellectual property rights, in advertising for sale and selling Inventory and other Collateral and to collect any amounts due under Accounts, contracts or Negotiable Collateral of Grantor; and

(g) to bring suit in its own name on behalf of the Holder to enforce the Trademarks, Patents, Copyrights and Intellectual Property Licenses and, if Agent shall commence any such suit, the appropriate Grantor shall, at the request of Agent, do any and all lawful acts and execute any and all proper documents reasonably required by Agent in aid of such enforcement (it being understood that Agent shall not be obligated to bring any such suit).

To the extent permitted by law, Grantor hereby ratifies all that such attorney-in-fact shall lawfully do or cause to be done by virtue hereof. This power of attorney is coupled with an interest and shall be irrevocable until this Agreement is terminated.

11. Appointment and Authorization of Agent. Holder hereby designates and appoints Agent as its representative under this Agreement and the other Note Documents and Holder hereby irrevocably authorizes Agent to execute and deliver each of the other Note Documents on its behalf and to take such other action on its behalf under the provisions of this Agreement and each other Note Document and to exercise such powers and perform such duties as are expressly delegated to Agent by the terms of this Agreement or any other Note Document, together with such powers as are reasonably incidental thereto. Agent agrees to act as such on the express conditions contained in this Section 11. The provisions of this Section 11 are solely for the benefit of Agent and the Holder, and Heron shall have no rights as a third party beneficiary of any of the provisions contained herein. Any provision to the contrary contained elsewhere in this Agreement or in any other Note Document notwithstanding, Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor shall Agent have or be deemed to have any fiduciary relationship with Holder, and no implied covenants, functions,

responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Note Document or otherwise exist against Agent; it being expressly understood and agreed that the use of the word “Agent” is for convenience only, that Agent is merely the representative of the Holder, and only has the contractual duties set forth herein. Except as expressly otherwise provided in this Agreement, Agent shall have and may use its sole discretion with respect to exercising or refraining from exercising any discretionary rights or taking or refraining from taking any actions that Agent expressly is entitled to take or assert under or pursuant to this Agreement and the other Note Documents. Without limiting the generality of the foregoing, or of any other provision of the Note Documents that provides rights or powers to Agent, Holder agrees that Agent shall have the right to exercise the following powers as long as this Agreement remains in effect: (a) maintain, in accordance with its customary business practices, ledgers and records reflecting the status of the Secured Obligations, the Collateral and related matters, (b) execute or file any and all financing or similar statements or notices, amendments, renewals, supplements, documents, instruments, proofs of claim, notices and other written agreements with respect to the Note Documents, (c) perform, exercise, and enforce any and all other rights and remedies of the Holder with respect to Heron, the Secured Obligations, the Collateral, or otherwise related to any of same as provided in the Note Documents, and (d) incur and pay such Expenses as Agent may deem necessary or appropriate for the performance and fulfillment of its functions and powers pursuant to the Note Documents. Agent shall have no obligation whatsoever to the Holder to assure that the Collateral exists or is owned by Heron or is cared for, protected, or insured or has been encumbered, or that the Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, or enforced or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure or fidelity, or to continue exercising, any of the rights, authorities and powers granted or available to Agent pursuant to any of the Note Documents, it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, subject to the terms and conditions contained herein, Agent may act in any manner it may deem appropriate, in its sole discretion given Agent’s own interest in the Collateral in its capacity as the Holder and that Agent shall have no other duty or liability whatsoever to any Holder as to any of the foregoing, except as otherwise provided herein.

12. Agent May Perform. If Grantor fails to perform any agreement contained herein and an Event of Default exists and is continuing, Agent may itself perform, or cause performance of, such agreement, and the reasonable expenses of Agent incurred in connection therewith shall be payable, jointly and severally, by Grantor.

13. Agent’s Duties. The powers conferred on Agent hereunder are solely to protect the Holder’s interest in the Collateral, for the benefit of the Holder, and shall not impose any duty upon Agent to exercise any such powers. Except for the safe custody of any Collateral in its actual possession and the accounting for moneys actually received by it hereunder, Agent shall have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral. Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its actual possession if such Collateral is accorded treatment substantially equal to that which Agent accords its own property.

14. Collection of Accounts, General Intangibles and Negotiable Collateral. At any time upon the occurrence and during the continuation of an Event of Default, Agent or Agent’s designee may (a) notify Account Debtors of Grantor that the Accounts, General Intangibles, Chattel Paper or Negotiable Collateral have been assigned to Agent, for the benefit of the Holder, or that Agent has a security interest therein, and (b) collect the Accounts, General Intangibles and Negotiable Collateral directly, and any collection costs and expenses shall constitute part of Grantor’s Secured Obligations under the Note Documents.

15. Disposition of Pledged Interests by Agent. None of the Pledged Interests existing as of the date of this Agreement are, and none of the Pledged Interests hereafter acquired on the date of acquisition thereof will be, registered or qualified under the various federal or state securities laws of the United States and disposition thereof after an Event of Default may be restricted to one or more private (instead of public) sales in view of the lack of such registration. Grantor understands that in connection with such disposition, Agent may approach only a restricted number of potential purchasers and further understands that a sale under such circumstances may yield a lower price for the Pledged Interests than if the Pledged Interests were registered and qualified pursuant to federal and state securities laws and sold on the open market. Grantor, therefore, agrees that: (a) if Agent shall, pursuant to the terms of this Agreement, sell or cause the Pledged Interests or any portion thereof to be sold at a private sale, Agent shall have the right to rely upon the advice and opinion of any nationally recognized brokerage or investment firm (but shall not be obligated to seek such advice and the failure to do so shall not be considered in determining the commercial reasonableness of such action) as to the best manner in which to offer the Pledged Interest or any portion thereof for sale and as to the best price reasonably obtainable at the private sale thereof; and (b) such reliance shall be conclusive evidence that Agent has handled the disposition in a commercially reasonable manner.

16. Voting Rights.

(a) Upon the occurrence and during the continuation of an Event of Default, (i) Agent may, at its option, and with two (2) Business Days prior notice to Grantor, and in addition to all rights and remedies available to Agent under any other agreement, at law, in equity, or otherwise, exercise all voting rights, and all other ownership or consensual rights in respect of the Pledged Interests owned by Grantor, but under no circumstances is Agent obligated by the terms of this Agreement to exercise such rights, and (ii) if Agent duly exercises its right to vote any of such Pledged Interests, Grantor hereby appoints Agent, Grantor’s true and lawful attorney-in-fact and irrevocable proxy to vote such Pledged Interests in any manner Agent deems advisable for or against all matters submitted or which may be submitted to a vote of shareholders, partners or members, as the case may be. The power-of-attorney granted hereby is coupled with an interest and shall be irrevocable.

(b) For so long as Grantor shall have the right to vote the Pledged Interests owned by it, Grantor covenants and agrees that it will not, without the prior written consent of Agent, vote or take any consensual action with respect to such Pledged Interests which would materially adversely affect the rights of Agent and the Holder solely in connection with their rights as holders of the Notes (and not in connection with their rights solely as holders of Stock).

17. Remedies. Upon the occurrence and during the continuance of an Event of Default:

(a) Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein, in the other Note Documents, or otherwise available to it, all the rights and remedies of a secured party on default under the Code or any other applicable law. Without limiting the generality of the foregoing, Grantor expressly agrees that, in any such event, Agent without demand of performance or other demand, advertisement or notice of any kind (except a notice specified below of time and place of public or private sale) to or upon Grantor or any other Person (all and each of which demands, advertisements and notices are hereby expressly waived to the maximum extent permitted by the Code or any other applicable law), may take immediate possession of all or any portion of the Collateral and (i) require Grantor to, and Grantor hereby agrees that it will at its own expense and upon the reasonable request of Agent forthwith, assemble all or part of the Collateral as directed by Agent and make it available to Agent at one or more locations where Grantor regularly maintains Inventory, and (ii) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of Agent’s offices or elsewhere, for cash, on credit, and upon such other commercially reasonable terms as Agent may request. Grantor agrees that, to the extent notice of sale shall be required by law, at least 10 days’ notice to Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification and specifically such notice shall constitute a reasonable “authenticated notification of disposition” within the meaning of Section 9-611 of the Code. Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

(b) Agent is hereby granted a license or other right to use, without liability for royalties or any other charge, Grantor’s labels, Patents, Copyrights, rights of use of any name, trade secrets, trade names, Trademarks, service marks and advertising matter, URLs, domain names, industrial designs, other industrial or intellectual property or any property of a similar nature, whether owned by Grantor or with respect to which Grantor have rights under license, sublicense, or other agreements, as it pertains to the Collateral, in preparing for sale, advertising for sale and selling any Collateral, and Grantor’s rights under all licenses and all franchise agreements shall inure to the benefit of Agent.

(c) Any cash held by Agent as Collateral and all cash proceeds received by Agent in respect of any sale of, collection from, or other realization upon all or any part of the Collateral shall be applied against the Note and the Secured Obligations, pari passu. In the event the proceeds of Collateral are insufficient to satisfy all of the Secured Obligations in full, Grantor shall remain liable for any such deficiency.

(d) Grantor hereby acknowledges that the Secured Obligations arose out of a commercial transaction, and agrees that if an Event of Default shall occur and be continuing Agent shall have the right to an immediate writ of possession without notice of a hearing. Agent shall have the right upon notice to Grantor to the appointment of a receiver for the properties and assets of Grantor, and Grantor hereby consents to such rights and such appointment and hereby waives any objection Grantor may have thereto or the right to have a bond or other security posted by Agent.

18. Remedies Cumulative. Each right, power, and remedy of Agent as provided for in this Agreement or in the other Note Documents or now or hereafter existing at law or in equity or by statute or otherwise shall be cumulative and concurrent and shall be in addition to every other right, power, or remedy provided for in this Agreement or in the other Note Documents or now or hereafter existing at law or in equity or by statute or otherwise, and the exercise or beginning of the exercise by Agent, of any one or more of such rights, powers, or remedies shall not preclude the simultaneous or later exercise by Agent of any or all such other rights, powers, or remedies.

19. Marshaling. Agent shall not be required to marshal any present or future collateral security (including but not limited to the Collateral) for, or other assurances of payment of, the Secured Obligations or any of them or to resort to such collateral security or other assurances of payment in any particular order, and all of its rights and remedies hereunder and in respect of such collateral security and other assurances of payment shall be cumulative and in addition to all other rights and remedies, however existing or arising. To the extent that it lawfully may, Grantor hereby agrees that it will not invoke any law relating to the marshaling of collateral which might cause delay in or impede the enforcement of Agent’s rights and remedies under this Agreement or under any other instrument creating or evidencing any of the Secured Obligations or under which any of the Secured Obligations is outstanding or by which any of the Secured Obligations is secured or payment thereof is otherwise assured, and, to the extent that it lawfully may, Grantor hereby irrevocably waives the benefits of all such laws.

20. Indemnity and Expenses.

(a) Grantor agrees to indemnify Agent and the Holder from and against all claims, lawsuits and liabilities (including reasonable attorneys’ fees) growing out of or resulting from this Agreement (including enforcement of this Agreement) or any other Note Document to which Grantor is a party, except claims, losses or liabilities resulting from the gross negligence or willful misconduct of the party seeking indemnification as determined by a final non-appealable order of a court of competent jurisdiction. This provision shall survive the termination of this Agreement and the repayment of the Secured Obligations.

(b) Grantor, jointly and severally, shall, upon demand, pay to Agent all the Expenses which Agent may incur in connection with (i) the administration of this Agreement, (ii) the custody, preservation, use or operation of, or, upon an Event of Default, the sale of, collection from, or other realization upon, any of the Collateral in accordance with this Agreement and the other Note Documents, (iii) the exercise or enforcement of any of the rights of Agent hereunder or (iv) the failure by Grantor to perform or observe any of the provisions hereof.

21. Waivers, Amendments; Etc. THIS AGREEMENT, TOGETHER WITH THE OTHER NOTE DOCUMENTS, REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

THERE ARE NO UNWRITTEN AGREEMENTS BETWEEN THE PARTIES WITH RESPECT TO THE MATTERS PERTAINING TO THIS AGREEMENT. No waiver of any provision of this Agreement, and no consent to any departure by Grantor herefrom, shall in any event be effective unless the same shall be in writing and signed by Agent, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No amendment of any provision of this Agreement shall be effective unless the same shall be in writing and signed by Agent and Grantor to which such amendment applies.

22. Addresses for Notices. All notices and other communications provided for hereunder shall be given in the form and manner and delivered to Agent and to Grantor, at their respective addresses specified in the Note, or, as to any party, at such other address as shall be designated by such party in a written notice to the other party.

23. Continuing Security Interest: Assignments under this Agreement. This Agreement shall create a continuing security interest in the Collateral and shall (a) remain in full force and effect until the Secured Obligations (other than inchoate indemnity obligations) have been paid in full in cash or redeemed or converted into Stock in accordance with the provisions of the Notes, (b) be binding upon Grantor and its successors and assigns, and (c) inure to the benefit of, and be enforceable by, Agent, and its successors, transferees and assigns. Without limiting the generality of the foregoing clause (c), each of Agent and the Holder may assign or otherwise transfer all or any portion of its rights and obligations under this Agreement to any other Person who receives transfer of any or all of the Note as permitted under the Note, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to Agent herein or otherwise upon such person becoming a “Holder”. Upon payment in full in cash or redemption or conversion of all the Secured Obligations (other than inchoate indemnity obligations) in accordance with the provisions of the Note, the Security Interest granted hereby shall automatically terminate and all rights to the Collateral shall revert to Grantor or any other Person entitled thereto. At such time, Agent authorizes Heron or any designee of Heron to file appropriate termination statements or take any other steps that Heron deems necessary to terminate such Security Interests. Except as provided herein, in the Note, no transfer or renewal, extension, assignment, or termination of this Agreement, any other Note Document, or any other instrument or document executed and delivered by Grantor to Agent nor any additional loans made by the Holder to Grantor, nor the taking of further security, nor the retaking or re-delivery of the Collateral to Grantor by Agent, nor any other act of the Holder, or any of them shall release Grantor from any obligation, except a release or discharge executed in writing by Agent. Agent shall not by any act, delay, omission or otherwise, be deemed to have waived any of its rights or remedies hereunder, unless such waiver is in writing and signed by Agent and then only to the extent therein set forth. A waiver by Agent of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which Agent would otherwise have had on any other occasion.

24. Governing Law.

(a) THIS AGREEMENT SHALL BE A CONTRACT MADE UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES (OTHER THAN SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW).

(b) ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER NOTE DOCUMENT, SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF THE STATE OF NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK; PROVIDED THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT AGENT’S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE FOUND. EACH GRANTOR HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE. EACH GRANTOR FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF DELAWARE. EACH GRANTOR HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. Each Grantor hereby appoints CT Corporation as such Grantor’s agent where notices and demands to or upon such Grantor in respect of this Agreement or any other Note Document may be served (without prejudice to the right of the Agent to serve process in any other manner permitted by law). If for any reason such process agent is unable to serve as such, such Grantor will within 30 days appoint a substitute process agent located in the State of Delaware and give notice of such appointment to Agent.

(c) EACH GRANTOR AND AGENT HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS AGREEMENT, ANY OTHER NOTE DOCUMENT AND ANY AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR WHICH MAY IN THE FUTURE BE DELIVERED IN CONNECTION HEREWITH OR THEREWITH OR ARISING FROM ANY LENDING RELATIONSHIP EXISTING IN CONNECTION WITH ANY OF THE FOREGOING, AND AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.

25. Agent. Each reference herein to any right granted to, benefit conferred upon or power exercisable by the “Agent” shall be a reference to Agent, for the benefit of the Holder.

26. Miscellaneous.

(a) This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same Agreement. Delivery of an executed counterpart of this Agreement by telefacsimile or

other electronic method of transmission shall be equally as effective as delivery of an original executed counterpart of this Agreement. Any party delivering an executed counterpart of this Agreement by telefacsimile or other electronic method of transmission also shall deliver an original executed counterpart of this Agreement but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Agreement. The foregoing shall apply to each other Note Document mutatis mutandis.

(b) Any provision of this Agreement which is prohibited or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof in that jurisdiction or affecting the validity or enforceability of such provision in any other jurisdiction.

(c) Headings used in this Agreement are for convenience only and shall not be used in connection with the interpretation of any provision hereof.

27. Subordination. Notwithstanding anything herein to the contrary, the indebtedness under this Agreement and the Lien and Security Interest granted to Agent pursuant to this Agreement and the other Note Documents and the exercise of any right or remedy by Agent hereunder and thereunder, are subject to the provisions of the Note. If there is a conflict between the terms of the Note and this Agreement or any Note Document, the terms of the Note will control. Notwithstanding anything to the contrary herein, to the extent an intercreditor agreement has been entered into in accordance with the Existing Security Agreement and for so long as such intercreditor agreement is in effect, (a) this Agreement will be subject in all respects to such intercreditor agreement, and (b) to the extent that there is a conflict between the terms of this Agreement and any intercreditor agreement, the intercreditor agreement shall control in all respects. For the avoidance of doubt, other than the Existing Notes, all Obligations under the Note and the Note Documents, shall be senior in right of payment to any other Indebtedness, and, in an Insolvency Proceeding or Change of Control, no payment shall be made on any Indebtedness (other than on the Existing Notes), until the Obligations under the Note and the Note Documents have been Paid in Full.

IN WITNESS WHEREOF, the undersigned parties hereto have executed this Agreement by and through their duly authorized officers, as of the day and year first above written.

PATENT SECURITY AGREEMENT

This PATENT SECURITY AGREEMENT (this “Patent Security Agreement”) is made as of August 5, 2016, among HERON THERAPEUTICS, INC., a Delaware corporation. (“Grantor”), and TANG CAPITAL PARTNERS, LP, in its capacity as a Holder and Agent.

RECITALS

WHEREAS, Heron has entered into that certain Secured Promissory Note (the “Note”) dated as of August 5, 2016 in favor of Agent, as Holder, and

WHEREAS, the Holder is willing to make the financial accommodations to Heron as provided for in the Note, but only upon the condition, among others, that Grantor shall have executed and delivered to Agent, as representative of the Holder for the benefit of the Holder, that certain Security Agreement dated as of August 5, 2016 (including all annexes, exhibits or schedules thereto, as from time to time amended, restated, supplemented or otherwise modified, the “Security Agreement”);

WHEREAS, pursuant to the Security Agreement, Grantor is required to execute and deliver to Agent this Patent Security Agreement;

NOW, THEREFORE, in consideration of the premises and mutual covenants herein contained and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Grantor hereby agrees as follows:

1. DEFINED TERMS. All capitalized terms used but not otherwise defined herein have the meanings given to them in the Security Agreement.

2. GRANT OF SECURITY INTEREST IN PATENT COLLATERAL. Grantor hereby grants to Agent a continuing security interest in all of Grantor’s right, title and interest in, to and under the following, whether presently existing or hereafter created or acquired (collectively, the “Patent Collateral”):

(a) all of its Patents and Patent Intellectual Property Licenses to which it is a party including those referred to on Schedule I hereto;

(b) all reissues, continuations or extensions of the foregoing; and

(c) all products and proceeds of the foregoing, including any claim by Grantor against third parties for past, present or future infringement or dilution of any Patent or any Patent licensed under any Intellectual Property License.

3. SECURITY FOR OBLIGATIONS. This Patent Security Agreement and the Security Interest created hereby secures the payment and performance of all the Secured Obligations, whether now existing or arising hereafter. Without limiting the generality of the foregoing, this Patent Security Agreement secures the payment of all amounts which constitute

part of the Secured Obligations and would be owed by Grantor, or any of them, to Agent, whether or not they are unenforceable or not allowable due to the existence of an Insolvency Proceeding involving Grantor.

4. SECURITY AGREEMENT. The security interests granted pursuant to this Patent Security Agreement are granted in conjunction with the security interests granted to Agent pursuant to the Security Agreement. Grantor hereby acknowledges and affirms that the rights and remedies of Agent with respect to the security interest in the Patent Collateral made and granted hereby are more fully set forth in the Security Agreement, the terms and provisions of which are incorporated by reference herein as if fully set forth herein.

5. AUTHORIZATION TO SUPPLEMENT. If Grantor shall obtain rights to any new patentable inventions or become entitled to the benefit of any patent application or patent for any reissue, division, or continuation, of any patent, the provisions of this Patent Security Agreement shall automatically apply thereto. Grantor shall give prompt notice in writing to Agent with respect to any such new patent rights. Without limiting Grantor’s obligations under this Section 5, Grantor hereby authorizes Agent unilaterally to modify this Agreement by amending Schedule I to include any such new patent rights of Grantor. Notwithstanding the foregoing, no failure to so modify this Patent Security Agreement or amend Schedule I shall in any way affect, invalidate or detract from Agent’s continuing security interest in all Collateral, whether or not listed on Schedule I.

6. COUNTERPARTS. This Patent Security Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such separate counterparts shall together constitute but one and the same instrument. In proving this Patent Security Agreement or any other Note Document in any judicial proceedings, it shall not be necessary to produce or account for more than one such counterpart signed by the party against whom such enforcement is sought. Any signatures delivered by a party by facsimile transmission or by e-mail transmission shall be deemed an original signature hereto.

7. CONSTRUCTION. Unless the context of this Patent Security Agreement or any other Note Document clearly requires otherwise, references to the plural include the singular, references to the singular include the plural, the terms “includes” and “including” are not limiting, and the term “or” has, except where otherwise indicated, the inclusive meaning represented by the phrase “and/or.” The words “hereof,” “herein,” “hereby,” “hereunder,” and similar terms in this Patent Security Agreement or any other Note Document refer to this Patent Security Agreement or such other Note Document, as the case may be, as a whole and not to any particular provision of this Patent Security Agreement or such other Note Document, as the case may be. Section, subsection, clause, schedule, and exhibit references herein are to this Patent Security Agreement unless otherwise specified. Any reference in this Patent Security Agreement or in any other Note Document to any agreement, instrument, or document shall include all alterations, amendments, changes, extensions, modifications, renewals, replacements, substitutions, joinders, and supplements, thereto and thereof, as applicable (subject to any restrictions on such alterations, amendments, changes, extensions, modifications, renewals, replacements, substitutions, joinders, and supplements set forth herein). Any reference herein or in any other Note Document to the satisfaction or repayment in full of the Secured Obligations shall mean the repayment in full in cash (or cash collateralization in accordance with the terms
