(b) Change Orders  Any material change in a Work Order shall require execution of an amendment to the Work Order (a “Change Order”).  Each Change Order shall set forth the changes to the applicable task, responsibility, duty, budget, timeline or other matters.  A Change Order will only become effective upon the execution of the Change Order by both Parties.

3. Term and Termination

(a) This Master Agreement shall commence on the Effective Date and shall have an initial term of three (3) years (the “Initial Term”), unless earlier terminated as provided herein.  The Initial Term will be automatically renewed for additional one (1) year terms (“Subsequent Term(s)”).  The Initial Term and any Subsequent Terms shall be referred to collectively as the “Term”.

(b) QUOIN may terminate this Master Agreement for any reason upon ninety (90) days prior written notice to THERAPEUTICS.

(c) Either Party may terminate any Work Order and this Master Agreement as it applies to such Work Order, upon written notice to the other Party, if the other Party materially breaches such Work Order and this Master Agreement as it applies to such Work Order.  Both Parties agree to allow the breaching Party a reasonable time, but not more than ninety (90) days, to use reasonable efforts to correct such a breach (other than a breach of payment obligations, as to which this sentence and the next sentence do not apply) and provide

reasonably satisfactory evidence of corrective actions in a timely manner.  Failure to cure such a breach within such 90-day period shall entitle the non-breaching Party to terminate the applicable Work Order and this Master Agreement as it applies to such Work Order, immediately by written notice to the breaching Party.  In case of any breach in a payment obligation under a Work Order, the non-breaching Party shall be entitled to terminate that Work Order and this Master Agreement as it applies to such Work Order, effective upon the expiration of five (5) business days after notice of such breach from the non-breaching Party to the breaching Party, if the breaching Party fails to cure the breach of such payment obligation within such five (5) business day period.

(f) In the event of termination of this Master Agreement or any Work Order, QUOIN and THERAPEUTICS agree to discuss, cooperate and coordinate termination of activities being conducted by THERAPEUTICS.  As soon as reasonably possible after receipt of any written termination notice by either Party, THERAPEUTICS will use commercially reasonable efforts to stop initiation of any tasks or activities not yet started as of the date of termination notice, whether to be conducted by THERAPEUTICS or a third party, unless another plan of termination is agreed to by both Parties.  However, both Parties acknowledge non-cancelable costs may exist and will require payment as detailed in Section 3(h).  In all cases of termination, a reasonable plan of action for cessation of activities will be agreed to by both Parties (such agreement not to be unreasonably conditioned, delayed or withheld) in order to ensure an orderly cessation of on-going tasks and activities and in order to protect the safety and rights of patients, as well as to facilitate compliance with the legal responsibilities of all Parties involved according to applicable local, federal and/or state laws, regulations and ordinances.  THERAPEUTICS will use commercially reasonable efforts to terminate all Work Order associated tasks according to the plan so agreed to by both Parties.

(g) Upon termination of this Master Agreement or any Work Order, THERAPEUTICS will, at QUOIN’s written request, promptly provide QUOIN with a copy of all records relating to Project performance and all periodic reports and/or patient records, maintaining confidentiality.

(i) In the event a Work Order is terminated by QUOIN before conclusion by reason of any uncured material breach by THERAPEUTICS pursuant to Section 3(c) above, any third-party pass-through costs associated with terminating the Work Order, e.g. laboratory costs, etc. will be:

(i) borne by THERAPEUTICS if attributable to THERAPEUTICS’s material breach of its obligations under the Master Agreement or Work Order and previously paid to THERAPEUTICS;

(ii) borne by QUOIN if not previously paid to THERAPEUTICS; or

(iii) borne by and as between QUOIN and THERAPEUTICS as they agree (such agreement not to be unreasonably conditioned, delayed or withheld) if neither of the above (i) and (ii) applies,

(j) Sections 3(f, g, h, and i), 5(b), 6, 7, 8, 10, 11, 12, 13, 15, 16(c), 24, 25 and 27 shall survive any expiration or termination of this Master Agreement to the extent of the terms detailed in each respective Section.
