shall have immediate and full access to any funds held in the Purchaser Concentration Account and such funds shall not be subject to any conditions or restrictions whatsoever. After the Daily Amount is swept into the Purchaser Concentration Account,
the amounts remaining in the Joint Concentration Account shall then be swept, at the direction of the Company, into the Company Concentration Account. The Company shall have immediate and full access to any funds held in the Company Concentration
Account and such funds shall not be subject to any conditions or restrictions whatsoever other than those of the Deposit Bank; provided, however, that nothing herein shall (i) affect or reduce the Company’s obligations to pay
in full all amounts due to Purchaser under this Agreement, or (ii) in any manner limit the recourse of Purchaser to the Assigned Interests Collateral to satisfy the Company’s Obligations.

agreement to remit to the Deposit Account when due all applicable payments in respect of sales and licensing revenue in respect of the Product and in respect of royalties received from Licensees that are due and payable to the Company in respect of
or derived from such agreement during the Revenue Interest Period and (ii) deliver to Purchaser evidence of such instruction and of such applicable party’s agreement thereto. Without in any way limiting the foregoing, commencing on the
Closing Date and thereafter, any and all payments in respect of sales of the Product received by the Company shall be deposited into the Deposit Account within two (2) Business Days of the Company’s receipt thereof.

 Section 5.15 Board Designee. 
 Effective immediately after the
Closing, Purchaser shall have the right to designate, and the Company shall appoint an individual designated by the Purchaser (the “Purchaser Designee”), who shall serve on the Board until the 2013 Annual Meeting of Shareholders
(the “2013 Annual Meeting”). For the 2013 Annual Meeting and each annual meeting thereafter 

  
 - 32 -









 
during the Term, the Board shall nominate and recommend the Purchaser Designee as a director nominee to serve on the Board until the next annual meeting and shall include such nomination in the
Company’s proxy statement for the 2013 Annual Meeting and each annual meeting thereafter, provided that the election of the Purchaser Designee is subject to shareholders’ approval. Should at any time there become a vacancy on the Board as
a result of (1) the resignation, death or removal of the Purchaser Designee or (2) such Purchaser Designee failing to obtain the requisite approval of the Company’s shareholders at any annual or special meeting of the Company’s
shareholders and where no other individual is elected to such vacancy, Purchaser shall have the right to designate an individual to fill such vacancy, and the Company shall take such actions necessary to appoint, such individual to the Board. The
Company shall have taken all actions necessary at or prior to the Closing to ensure there is a vacancy on the Board as of the Closing to permit the appointment of the Purchaser Designee to the Board as of the Closing. 

Section 5.16 Rights to Future Stock Issuances. 

Subject to the terms and conditions of this Section 5.16 and applicable securities laws, if the Company proposes to offer or
sell any New Securities, the Company shall first offer such New Securities to the Purchaser. The Purchaser shall be entitled to apportion the right of first offer hereby granted to it among itself and its Affiliates in such proportions as it deems
appropriate. 
 (a) The Company shall give notice (the “Offer Notice”) to the Purchaser, stating (i) its
bona fide intention to offer such New Securities, (ii) the number of such New Securities to be offered, and (iii) the price and terms, if any, upon which it proposes to offer such New Securities. 

(b) By notification to the Company within five (5) days after the Offer Notice is given, the Purchaser may elect to purchase or
otherwise acquire, at the price and on the terms specified in the Offer Notice, up to * * * of such New Securities. The closing of any sale pursuant to this Section 5.16(b) shall occur within the later of one hundred and twenty
(120) days of the date that the Offer Notice is given and the date of initial sale of New Securities pursuant to Section 5.16(c). 
 (c) If all New Securities referred to in the Offer Notice are not elected to be purchased or acquired as provided in Section 5.16(b), the Company may, during the ninety (90) day period
following the expiration of the periods provided in Section 5.16(b), offer and sell such New Securities (including any portion of New Securities Purchaser declined to acquire pursuant to Section 5.16(b)) to any Person or
Persons at a price not less than, and upon terms no more favorable to the offeree than, those specified in the Offer Notice. If the Company does not enter into an agreement for the sale of the New Securities within such period, or if such agreement
is not consummated within thirty (30) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such New Securities shall not be offered unless first reoffered to the Purchaser in accordance with this
Section 5.16. 
 (d) The right of first offer in this Section 5.16 shall not be applicable to
(i) issuance of options under the Company’s equity compensation plans, where such plans have been approved by the Company’s shareholders; and (ii) issuance of equity securities to one or more counterparties in connection with the
consummation, by the Company, of a strategic partnership, 

  
 - 33 -









 
joint venture, collaboration or acquisition or license of any business products or technology (it being understood and agreed that the primary purpose of any issuance pursuant to this clause
(ii) shall not be to raise capital). 
 (e) The Purchaser shall agree to treat the Offer Notice as confidential, and it
shall not trade any securities of the Company while the terms of the Offer Notice remain as material, non-public information. 

Section 5.17 Dividends.  
 During the period from the Closing Date to sixty (60) days after the fourth anniversary of the Closing Date (or the payment of the Put Price in the event the Put Option is exercised on or prior to 60
days after the fourth anniversary of the Closing Date), the Company shall not, nor shall it permit any Subsidiary to, declare, pay or make any dividend or distribution on any shares of the common stock or preferred stock of such Person (other than
dividends or distributions payable in its stock, or split-ups or reclassifications of its stock) or apply any of its funds, property or assets to the purchase, redemption or other retirement of any common or preferred stock, or of any options to
purchase or acquire any such shares of common or preferred stock of any such Person (collectively, “Restricted Payments”), except that: (a) each Subsidiary may make direct or indirect Restricted Payments to the Company; and
(b) the Company and each Subsidiary may purchase, redeem or otherwise acquire Equity Interests issued by it solely with the proceeds received from the substantially concurrent issue of new shares of its common stock or other common Equity
Interests. For purposes of this Agreement, “Equity Interests” of any Person means any and all shares, rights to purchase, options, warrants, general, limited or limited liability partnership interests, member interests,
participation or other equivalents of or interest in (regardless of how designated) equity of such Person, whether voting or nonvoting, including common stock, preferred stock, convertible securities or any other “equity security” (as such
term is defined in Rule 3a11-1 of the General Rules and Regulations promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended).

 MISCELLANEOUS 
 Section 7.01 Survival.

 Section 7.04 Successors and Assigns. 

The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and
assigns. The Company shall not be entitled to assign any of its obligations and rights under the Transaction Documents without the prior written consent of Purchaser. Solely upon the consent of the Company (which consent may not be unreasonably
withheld, delayed or conditioned), Purchaser may assign any of its obligations or rights under the Transaction Documents without restriction; provided, however, that Purchaser, notwithstanding such assignment, will remain liable under
Section 5.08(g) (to the extent of any amount subject thereto during the Fiscal Quarter as of the date of such assignment) and Section 7.05. 
 Section 7.05 Indemnification. 

  
 - 36 -









 (a) The Company hereby indemnifies and holds Purchaser and its Affiliates and any of their
respective partners, directors, managers, members, officers, employees and agents (each, a “Purchaser Indemnified Party”) harmless from and against any and all Losses (including all Losses in connection with any product liability
claims or claims of infringement or misappropriation of any Intellectual Property rights of any Third Parties) incurred or suffered by any Purchaser Indemnified Party arising out of any breach of any representation, warranty or certification made by
the Company in any of the Transaction Documents or certificates given by the Company in writing pursuant hereto or thereto or any breach of or default under any covenant or agreement by the Company pursuant to any Transaction Document, including any
failure by the Company to satisfy any of the Excluded Liabilities and Obligations. 
 (b) Purchaser hereby indemnifies and holds
the Company, its Affiliates and any of their respective partners, directors, managers, officers, employees and agents (each, a “Company Indemnified Party”) harmless from and against any and all Losses incurred or suffered by a
Company Indemnified Party arising out of any breach of any representation, warranty or certification made by Purchaser in any of the Transaction Documents or certificates given by Purchaser in writing pursuant hereto or thereto or any breach of or
default under any covenant or agreement by Purchaser pursuant to any Transaction Document. 
 (c) If any claim, demand, action
or proceeding (including any investigation by any Governmental Authority) shall be brought or alleged against an indemnified party in respect of which indemnity is to be sought against an indemnifying party pursuant to the preceding paragraphs, the
indemnified party shall, promptly after receipt of notice of the commencement of any such claim, demand, action or proceeding, notify the indemnifying party in writing of the commencement of such claim, demand, action or proceeding, enclosing a copy
of all papers served, if any; provided, that the omission to so notify such indemnifying party will not relieve the indemnifying party from any liability that it may have to any indemnified party under the foregoing provisions of this
Section 7.05 unless, and only to the extent that, such omission results in the forfeiture of, or has a material adverse effect on the exercise or prosecution of, substantive rights or defenses by the indemnifying party. In case any such
action is brought against an indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after
notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 7.05 for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, an indemnified party shall have the right to retain its own counsel, but the reasonable fees
and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the indemnifying party has assumed
the defense of such proceeding and has failed within a reasonable time to retain counsel reasonably satisfactory to such indemnified party or (iii) the named parties to any such proceeding (including any impleaded parties) include both the
indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interests between them based on the advice of such counsel. It is agreed that the
indemnifying party shall not, in 

  
 - 37 -









 
connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate law firm (in addition to local counsel
where necessary) for all such indemnified parties. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the
plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party,
effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. 

(d) To the extent that any breach by the Company of this Agreement does not trigger a Put Option Event, Purchaser’s sole remedy
shall be to recover any monetary damages associated with such breach, subject to the other terms and provisions contained in this Agreement. 
 Section 7.06 No Implied Representations and Warranties. 
 Each
party acknowledges and agrees that, other than the representations and warranties specifically contained in any of the Transaction Documents or certificates given in writing by a party hereto or thereto, there are no representations or warranties of
either party or any other Person either expressed or implied with respect to the Assigned Interests or the transactions contemplated hereby. Without limiting the foregoing, Purchaser acknowledges and agrees that (a) Purchaser and its
Affiliates, together with its and its Affiliates’ representatives, have made their own investigation of the Product and the Intellectual Property and are not relying on any implied warranties or upon any representation or warranty whatsoever as
to the future amount or potential amount of the Assigned Interests or as to the creditworthiness of Company and (b) except as expressly set forth in any representation or warranty in a Transaction Document, Purchaser shall have no claim or
right to indemnification pursuant to Section 7.05 (or otherwise) with respect to any information, documents or materials furnished to Purchaser, any of its Affiliates, or any of its or its Affiliates’ representatives, including any
information, documents or material made available to Purchaser and its Affiliates and its Affiliates’ representatives in any data room, presentation, interview or any other form relating to the transactions contemplated hereby. 

Section 7.07 Independent Nature of Relationship. 

(a) The relationship between the Company and its Subsidiary, on the one hand, and Purchaser, on the other, is solely that of seller and
purchaser, and neither Purchaser, on the one hand, nor the Company and its Subsidiary, on the other, has any fiduciary or other special relationship with the other or any of their respective Affiliates. Nothing contained herein or in any other
Transaction Document shall be deemed to constitute the Company and its Subsidiary and Purchaser as a partnership, an association, a joint venture or other kind of entity or legal form. 

(b) No officer or employee of Purchaser will be located at the premises of the Company or any of its Affiliates, except in connection
with an audit performed pursuant to 

  
 - 38 -









 
Section 5.02. No officer, manager or employee of Purchaser shall engage in any commercial activity with the Company or any of its Affiliates other than as contemplated herein and in
the other Transaction Documents. 
 (c) The Company and/or any of its Affiliates shall not at any time obligate Purchaser, or
impose on Purchaser any obligation, in any manner or respect to any Person not a party hereto. 
 Section 7.08
Federal Tax. 
 Notwithstanding the accounting treatment thereof, for United States federal, state and local tax
purposes, the Company and Purchaser shall treat the transactions contemplated by the Transaction Documents as debt for United States tax purposes. The parties hereto agree not to take any position that is inconsistent with the provision of this
Section 7.08 on any tax return or in any audit or other administrative or judicial proceeding unless (a) the other party to this Agreement has consented to such actions, which consent shall not be unreasonably withheld, or
(b) the party that contemplates taking such an inconsistent position has been advised by its tax advisor in writing that it is more likely than not (i) that there is no “reasonable basis” (within the meaning of Treasury
Regulation Section 1.6662-3(b)(3)) for the position specified in this Section 7.08 or (ii) that taking such a position would otherwise subject the party to penalties under the Internal Revenue Code of 1986, as amended.

 Section 7.09 Entire Agreement. 
 This Agreement, together with the Exhibits and Schedules hereto (which are incorporated herein by reference), and the other Transaction Documents constitute the entire agreement between the parties with
respect to the subject matter hereof and supersede all prior agreements (including the Term Sheet and the Interim Revenue Interest Purchase Agreement), understandings and negotiations, both written and oral, between the parties with respect to the
subject matter of this Agreement. No representation, inducement, promise, understanding, condition or warranty not set forth herein (or in the Exhibits, Schedules or other Transaction Documents) has been made or relied upon by either party hereto.
None of this Agreement, nor any provision hereof, is intended to confer upon any Person other than the parties hereto any rights or remedies hereunder. 
 Section 7.10 Amendments; No Waivers. 
 (a) This Agreement or any
term or provision hereof may not be amended, changed or modified except with the written consent of the parties hereto. No waiver of any right hereunder shall be effective unless such waiver is signed in writing by the party against whom such waiver
is sought to be enforced. 
 (b) No failure or delay by either party in exercising any right, power or privilege hereunder shall
operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not
exclusive of any rights or remedies provided by law. 
 Section 7.11 Interpretation. 

  
 - 39 -









 When a reference is made in this Agreement to Articles, Sections, Schedules or Exhibits,
such reference shall be to an Article, Section, Schedule or Exhibit to this Agreement unless otherwise indicated. The words “include”, “includes” and “including” when used herein shall be deemed in each case to be
followed by the words “without limitation”. Neither party hereto shall be or be deemed to be the drafter of this Agreement for the purposes of construing this Agreement against one party or the other. 

Section 7.12 Headings and Captions. 
 The headings and captions in this Agreement are for convenience and reference purposes only and shall not be considered a part of or affect the construction or interpretation of any provision of this
Agreement. 
 Section 7.13 Counterparts; Effectiveness. 

This Agreement may be executed in two or more counterparts, each of which shall be an original, but all of which together shall constitute
one and the same instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by the other parties hereto. Any counterpart may be executed by facsimile or pdf signature and such facsimile
or pdf signature shall be deemed an original. 
 Section 7.14 Severability. 

If any provision of this Agreement is held to be invalid or unenforceable, the remaining provisions shall nevertheless be given full force
and effect. 
 Section 7.15 Expenses. 

The Company will pay all of its own fees and expenses in connection with entering into and consummating the transactions contemplated by
this Agreement. The Company shall, promptly (and, in any event, within five (5) Business Days) upon demand, reimburse Purchaser up to * * * for its reasonable legal fees and expenses incurred in connection with the transactions contemplated by
the Transaction Documents, less any amounts reimbursed in connection with the Interim Royalty Purchase Agreement, not to exceed * * * in the aggregate. 
 Section 7.16 Governing Law; Jurisdiction. 
 (a) This Agreement
shall be governed by, and construed, interpreted and enforced in accordance with, the laws of the state of New York, without giving effect to the principles of conflicts of law thereof. 

(b) Any legal action or proceeding with respect to this Agreement or any other Transaction Document may be brought in any state or
federal court of competent jurisdiction in the State of Nevada, Washoe County and city of Reno. By execution and delivery of this Agreement, each party hereto hereby irrevocably consents to and accepts, for itself and in respect of its property,
generally and unconditionally the non-exclusive jurisdiction of such courts. Each party hereto hereby further irrevocably waives any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens, which it
may now or hereafter 

  
 - 40 -









 
have to the bringing of any action or proceeding in such jurisdiction in respect of any Transaction Document. 
 (c) Each party hereto hereby irrevocably consents to the service of process out of any of the courts referred to in subsection (b) of this Section 7.16 in any such suit, action or
proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to it at its address set forth in this Agreement. Each party hereto hereby irrevocably waives any objection to such service of process and further
irrevocably waives and agrees not to plead or claim in any suit, action or proceeding commenced hereunder or under any other Transaction Document that service of process was in any way invalid or ineffective. Nothing herein shall affect the right of
a party to serve process on the other party in any other manner permitted by law. 
 Section 7.17 Waiver of Jury
Trial. 
 Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all
right to trial by jury in any action, proceeding, claim or counterclaim arising out of or relating to any Transaction Document or the transactions contemplated under any Transaction Document. This waiver shall apply to any subsequent amendments,
renewals, supplements or modifications to any Transaction Document.
