ARTICLE XV.

TERM AND TERMINATION

15.1 The term of this Agreement will commence on the Effective Date and remain in full force and effect until the expiration of the last patent within the Sublicensed Patents, unless earlier termination by either (i) termination of all of the MD Anderson License Agreements, or (ii) pursuant to the terms of this Agreement (“Term”).

15.2 Subject to any rights herein which survive termination, this Agreement will earlier terminate in its entirety:

| a. | Automatically, if WPD becomes bankrupt or insolvent and/or if the business of WPD shall be placed in the hands of a receiver or trustee, whether by voluntary act of WPD or otherwise; or

| b. | Upon thirty (30) calendar days written notice from MBI, if WPD materially breaches or defaults on the payment or report obligations of Article VI, or use of name obligations of Article XI, or any obligation set forth in Article IV, unless before the end of such thirty (30) calendar day notice period, WPD has cured the material default or breach to MBI’s reasonable satisfaction, and so notifies MBI, stating the manner of the cure; or

| c. | Upon ninety (90) calendar days written notice from MBI if WPD materially breaches or defaults on any other obligation under this Agreement, unless, before the end of such ninety (90) calendar day period, WPD has cured the material default or breach to MBI’s reasonable satisfaction, and so notifies MBI, stating the manner of the cure; or

| d. | At any time by mutual written agreement between WPD and MBI upon one hundred eighty (180) calendar days written notice to all Parties and subject to any terms herein which survive termination; or

| e. | Immediately, upon written notice from MBI, if WPD brings any action before any court, agency or tribunal seeking to invalidate or otherwise challenge the enforceability of MBI’s, UTMDACC’s or the Board's ownership of any patent included in the Sublicensed Patent Rights. Any dispute regarding the validity, enforceability or ownership of any patent included in the Patent Rights shall be litigated in the courts located in Houston, Texas, and WPD agrees not to challenge personal jurisdiction in that forum. To the extent that WPD unsuccessfully challenges the validity or enforceability of any patent included in the Patent Rights, WPD agrees to reimburse MBI, UTMDACC and Board for all costs and fees (including attorney's fees) paid by MBI, UTMDACC and Board in defending against such challenge. WPD understands and agrees that, in the event WPD successfully challenges the validity or enforceability of any patent included in the Patent Rights, all payments or other consideration made or otherwise provided by WPD to MBI, UTMDACC or the Board prior to a final, non-appealable adjudication of invalidity and/or unenforceability shall be non-refundable.

| f. | Notwithstanding any terms to the contrary, if WPD has defaulted or been late on its payment obligations pursuant to this Agreement for a period of five (5) calendar days after notice from MBI of such default or failure to pay on any two (2) occasions in a twelve (12)-month period. Notwithstanding the foregoing, WPD may avoid termination under this Section, if WPD pays all past due amounts and a default waiver fee of $50,000.00 within thirty (30) calendar days following the receipt of written notice from MBI identifying the second payment default in the twelve (12) month period. WPD may avoid termination as provided in the foregoing sentence (by payment of all past due amounts and default waiver fee) a maximum of three (3) times during the Term of this Agreement. For purposes of clarification, a separate default waiver fee of $50,000.00 shall be due each time WPD seeks to avoid termination under this provision. It is understood that time is of the essence with respect to the default waiver fees, and these fees are not subject to the thirty (30) day cure period specified in Section 15.2(b); or

Any dispute between the Parties regarding or related to this Agreement shall be litigated in the courts located in Houston, Texas, and WPD agrees not to challenge personal jurisdiction in that forum.

16.7 If any provision of this Agreement or application thereof to anyone is adjudicated to be invalid or unenforceable, such invalidity or unenforceability shall not affect any provision or application of this Agreement which can be given effect without the invalid or unenforceable provision or application, and shall not invalidate or render unenforceable such provision or application. Further, the judicial or other competent authority making such determination shall have the power to limit, construe or reduce the duration, scope, activity and/or area of such provision, and/or delete specific words or phrases as necessary to render, such provision enforceable.

16.8 The headings used in this Agreement have been inserted for convenience of reference only and do not define or limit the provisions hereof. The Exhibits (if any) to this Agreement are incorporated herein by reference and will be deemed a part of this Agreement. Unless otherwise expressly provided herein or the context of this Agreement otherwise requires, (a) words of any gender include each other gender, (b) words such as “herein”, “hereof”, and “hereunder” refer to this Agreement as a whole and not merely to the particular provision in which such words appear, (c) words using the singular will include the plural, and vice versa, (d) the words “include,” “includes” and “including” will be deemed to be followed by the phrase “but not limited to”, “without limitation”, “inter alia” or words of similar import, (e) the word “or” will be deemed to include the word “and” (e.g., “and/or”) and (f) references to “ARTICLE,” “Section,” “subsection”, “clause” or other subdivision, or to a Schedule or Exhibit, without reference to a document are to the specified provision, Schedule or Exhibit of this Agreement. This Agreement will be construed as if it were drafted jointly by the Parties and shall not be strictly construed against either Party.

16.9 Except for the payment of any amount due hereunder (other than any amount disputed in good faith), neither Party shall be liable to the other for any failure or delay in the fulfillment of its obligations under this Agreement, when any such failure or delay is caused by fire, flood, earthquakes, locusts, explosions, sabotage, terrorism, lack of adequate raw materials (caused by matters beyond the reasonable control of the performing Party), civil commotions, riots, invasions, wars, peril of the sea, acts, restraints, requisitions, regulations, or directions of government authorities (caused by matters beyond the reasonable control of the performing Party), acts of God, or any similar cause beyond the reasonable control of the performing Party (each, a “Force Majeure Event”). In the event that either Party is prevented from discharging its obligations under this Agreement on account of a Force Majeure Event, the performing Party will notify the other Party forthwith, and will nevertheless make every endeavor, in the utmost good faith, to discharge its obligations, even if in a partial or compromised manner. For clarity, a Force Majeure Event shall not excuse a Party from its obligation to pay any money due hereunder.

IN WITNESS WHEREOF, the Parties hereto have executed this Agreement by their duly authorized representatives with full right, power and authority to enter into and perform under this Agreement.
