 6.6 Recalls. In the event that DUSA is required by any regulatory agency to recall the Light Source or if DUSA voluntarily initiates a recall of the Light Source and in either case such recall is a
result of a breach of any of the warranties under Section 6.1.1 through 6.1.3 above, [c.i.]. NBC will notify DUSA of any information, which may lead to recall of any Light Source. In case of a voluntary recall of the Light Source, DUSA will
retrieve all units of the Light Source, as the case may be, at its expense, with all direct expense: (a) to be reimbursed by NBC immediately where recall is the sole responsibility of NBC; and (b) to be borne by DUSA where recall is the
sole responsibility of DUSA. In situations of shared responsibility, costs will be shared equally by the parties. In addition, NBC agrees to cooperate with and assist DUSA in locating and retrieving, if necessary, units of the Light Source recalled
for any reason. A recall of DUSA’s products (including the Light Source) for any reasons other than those set forth in this Section 6.6 (including reasons due to force majeure) above shall not affect DUSA’s obligation to purchase
Light Source units in accordance with Article 2 herein above, as may be modified, or DUSA’s obligation under any outstanding purchase order hereunder. 
 6.7 Documentation. NBC agrees to develop and provide to DUSA documentation describing routine maintenance, service and care of the Light Source. In addition, upon DUSA’s request, NBC agrees to
provide DUSA such other information and documentation as DUSA may reasonably require in order to fulfill standard maintenance and support requirements on reasonable and customary terms and conditions.

 ARTICLE 8 

TERM AND TERMINATION 
 8.1 Term. The term of this Agreement shall commence on the Effective Date and continue in full force until December 31, 2013, unless terminated earlier in accordance with this Article 8 and
may, at DUSA’s sole option, be renewed for an additional two (2) years, subject only to agreement on price terms, provided that DUSA has purchased, or has a viable open purchase order for a minimum of three-hundred (300) Light Source
units within the term of this Agreement. Alternatively, this Agreement may be extended for an additional period by mutual written agreement of NBC and DUSA [c.i.]; provided, however, that neither NBC nor DUSA shall be obligated to approve any such
extension and shall have no liability whatsoever by reason of any failure to agree on any such extension. 
 8.2 Breach.
This Agreement may be terminated and/or any outstanding purchase order may be canceled by either party if the other party breaches any material term or condition of this Agreement and fails to remedy the breach within [c.i.] after being given
written notice thereof. Notwithstanding the foregoing, in the event of breach by either party, the other party’s right to terminate shall be stayed if the breaching party proposes a mutually agreeable plan to remedy such breach within the
foregoing [c.i.] and remedies such breach within [c.i.] after being given written notice thereof. It is understood and agreed that this Section 8.2 is subject to the provisions of Section 12.3 below, excusing performance where performance
is rendered impossible due to a Force Majeure Event, including without limitation failure of suppliers, in each case where such failure is beyond the reasonable control of the nonperforming party. For avoidance of doubt, among other things a delay
by NBC of more than [c.i.] of the delivery date of any shipment of Light Source ordered in accordance with Section 2.2 shall be deemed material. 
 8.3 Convenience. Either party may terminate this Agreement upon twelve (12) months’ prior written notice to the other party.

proceeding is not dismissed with prejudice [c.i.] after filing. 
 8.5 Survival. It is understood that termination or
expiration of this Agreement shall not relieve a party from any liability which, at the time of such termination or expiration, has already accrued to the other party, including NBC’s obligations during the Support Period. The provisions of
Sections 3.3, 3.4, 4.2, 8.4 and 8.5 and Articles 1, 5, 6, 9, 11, and 12 shall survive the termination of this Agreement for any reason. Except as otherwise expressly provided in this Article 8, all other rights and obligations of the parties shall
terminate upon termination of this Agreement.

12.9 Non-Waiver. Any waiver of the terms and conditions hereof must be explicitly in writing. The waiver by either of the parties
