7.3        Remedies, Generally.

(a)        If any Event of Default shall have occurred and be continuing, the Secured Party may exercise in respect of the Collateral, in addition to all other rights and remedies provided for herein or otherwise available to it at law or in equity, all the rights and remedies of the Secured Party on default under the UCC (whether or not the UCC applies to the affected Collateral) to collect, enforce or satisfy any Secured Obligations then owing, whether by acceleration or otherwise, and also may pursue any of the following separately, successively or simultaneously; provided, however, that in the event of a Sub-License Default or Operating Agreement Covenant Default the Secured Party’s right to commence any proceeding to foreclose its security interest against the Collateral shall not occur and Secured Party shall not collect any rights to payment Collateral under UCC Section 9607 prior to the expiration of [***] following entry of any final non-appealable judgment for monetary damages by a court of competent jurisdiction against Company, which judgment remains unpaid in full or unstayed by court order or otherwise:

(i)          require Grantor to, and Grantor hereby agrees that it shall at its expense and promptly upon request of the Secured Party forthwith, assemble all or part of the Collateral as directed by the Secured Party and make it available to the Secured Party at a place to be designated by the Secured Party that is reasonably convenient to both parties;

(ii)         enter onto the property where any Collateral is located and take possession thereof with or without judicial process;

(iii)        without notice except as specified below or under the UCC, sell, assign, lease, license (on an exclusive or nonexclusive basis) or otherwise dispose of the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Secured Party’s offices or elsewhere, for cash, on credit or for future delivery, at such time or times and at such price or prices and upon such other terms as the Secured Party may deem commercially reasonable; and

(iv)        to direct Grantor to refrain from practicing or using the Collateral in any manner whatsoever, directly or indirectly, and, if requested by the Secured Party, to execute such other and further documents that the Secured Party may request to further confirm this and to transfer ownership of the Collateral and any associated goodwill.

(b)        The Secured Party may be the purchaser of any or all of the Collateral at any public or private (to the extent the portion of the Collateral being privately sold is of a kind that is customarily sold on a recognized market or the subject of widely distributed standard price quotations) sale in accordance with the UCC and the Secured Party shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Collateral sold at any such sale made in accordance with the UCC, to use and apply any of the Secured Obligations as a credit on account of the purchase price for any Collateral payable by the Secured Party at such sale. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of Grantor, and Grantor hereby waives (to the fullest extent permitted by applicable law) all rights of redemption, stay and/or appraisal which it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. Grantor agrees that, to the extent notice of sale shall be required by law, at least [***] 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. The Secured Party shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Secured Party 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. Grantor hereby waives to the fullest extent permitted by applicable law any claims against the Secured Party arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price which might have been obtained at a public sale, even if the Secured Party accepts the first offer received and does not offer such Collateral to more than one offeree. If the proceeds of any sale or other disposition of the Collateral are insufficient to pay all the Secured Obligations, Grantor shall be liable for the deficiency and the fees of any attorneys employed by the Secured Party to collect such deficiency. Grantor further agrees that a breach of any of the covenants contained in this Section will cause irreparable injury to the Secured Party, that the Secured Party has no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section shall be specifically enforceable against Grantor, and Grantor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no default has occurred giving rise to the Secured Obligations becoming due and payable prior to their stated maturities. Nothing in this Section shall in any way alter the rights of the Secured Party hereunder.

This Agreement shall be binding upon Grantor, its successors and assigns, and inure, together with the rights and remedies of the Secured Party hereunder, to the benefit of the Secured Party and its successors, transferees and assigns. “Change of Control” shall mean (a) the consummation of a reorganization, merger or consolidation, or sale or other disposition of substantially all of the assets of Hansen, or (b) the acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1933, as amended) of beneficial ownership (within the meaning of Rule 13d-3 promulgated under such Act) of more than fifty percent (50%) of either (i) the then-outstanding shares of common stock of Hansen; or (ii) the combined voting power of the then-outstanding voting securities of Hansen entitled to vote generally in the election of directors. Without limiting the generality of the foregoing, but subject to the terms of the Sublicense Agreement, the Secured Party may assign or otherwise transfer the Sublicense Agreement held by it to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to Secured Party herein or otherwise. Upon the expiration of the terms of the Sublicense Agreement or the termination of any sublicense in whole or in part thereunder, the security interest granted hereby shall automatically terminate hereunder and of record as to such terminated rights and all rights to the Collateral relating to such terminated sublicense or portions thereof shall revert to Grantor. Upon any such termination the Secured Party shall, at Grantors’ expense, execute and deliver to Grantor or otherwise authorize the filing of such documents as Grantor shall reasonably request, including financing statement amendments to evidence such termination. The Secured Party shall, at Grantor’s expense, execute and deliver or otherwise authorize the filing of such documents as Grantor shall reasonably request, in form and substance reasonably satisfactory to the Secured Party, including financing statement amendments to evidence such release.

SECTION 9.    STANDARD OF CARE; SECURED PARTY MAY PERFORM.

The powers conferred on the Secured Party hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the exercise of reasonable care in the custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Secured Party 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. The Secured Party shall be deemed to have exercised reasonable care in the custody and preservation of Collateral in its possession if such Collateral is accorded treatment substantially equal to that which the Secured Party accords its own property. Neither the Secured Party nor any of its directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of Grantor or otherwise. If Grantor 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 payable by Grantor.

SECTION 10.    MISCELLANEOUS.

10.1        Notice. Any notice required or permitted to be given under this Agreement shall be given in accordance with Section 14 of the Sublicense Agreement.

10.2        Waivers and Enforcement of Rights. The failure of the Secured Party to exercise any right or remedy or option provided for herein or otherwise shall not be deemed to be a waiver of any of the covenants or obligations secured by this Agreement or otherwise. All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available. No sale of all or any of the Collateral, no forbearance on the part of the Secured Party, no release or partial release of any of the Collateral, and no extension; whether oral or in writing, of the time for the payment of the whole or any part of the Secured Debt or any other indulgence given by the Secured Party to Grantor or any other Person, shall operate to release or in any manner affect the Lien of the Agreement or the original liability of Grantor. A waiver by the Secured Party on any one occasion shall not be construed as a bar to or waiver of any right or remedy on any future occasion. No waiver or consent shall be binding upon the Secured Party unless it is in writing and signed by the Secured Party. Grantor waives any requirement of diligence or promptness on the Secured Party’s part in the enforcement of its rights under the provisions of this Agreement. To the fullest extent Grantor may do so, Grantor agrees that it will not at any time insist upon, plead, claim or take the benefit or advantage of any law now or hereafter in force providing for any appraisement, valuation, stay, extension or redemption, and Grantor, to the extent permitted by law, hereby waives and releases all rights of redemption, valuation, appraisement, stay of execution, and marshalling in the event of foreclosure of the Liens hereby created. If any law referred to in this Section and now in force, of which Grantor or other Person may take advantage despite this Section, shall hereafter be repealed or cease to be in force, such law shall not thereafter be deemed to preclude the application of this Section.

10.3        Miscellaneous. In case any provision in or obligation under this Agreement shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby. All covenants hereunder shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or would otherwise be within the limitations of, another covenant shall not avoid the occurrence of an Event of Default if such action is taken or condition exists. This Agreement shall be binding upon and inure to the benefit of the Secured Party and Grantor and their respective successors and assigns. Grantor shall not, without the prior written consent of the Secured Party, assign any right, duty or obligation hereunder. This Agreement embodies the entire agreement and understanding between Grantor and the Secured Party and supersede all prior agreements and understandings between such parties relating to the subject matter hereof and thereof. Accordingly, this Agreement may not be contradicted by evidence of prior, contemporaneous or subsequent oral agreements of the parties. There are no unwritten oral agreements between the parties. This Agreement may be executed in one or more counterparts (including by facsimile signature) and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same instrument; signature pages may be detached from multiple separate counterparts and attached to a single counterpart so that all signature pages are physically attached to the same document.

15

THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO ITS CONFLICTS OF LAW PROVISIONS. ANY DISPUTE BETWEEN THE PARTIES IN CONNECTION WITH THIS AGREEMENT (INCLUDING ANY QUESTION REGARDING ITS EXISTENCE, VALIDITY OR TERMINATION) SHALL BE SUBMITTED TO THE COMPETENT COURTS OF THE STATE OF NEW YORK.

16

IN WITNESS WHEREOF, Grantor and the Secured Party have caused this Agreement to be duly executed and delivered by their respective officers thereunto duly authorized as of the date first written above.
