(a) If HPI learns of any substantial infringement of the 412 Patent Rights, HPI shall so inform Callisto.

HPI or the Inventors may voluntarily join such suit and may be represented by counsel of their choice, each at their own expense. Callisto may not join HPI or the Inventors in a suit initiated by Callisto without such party's prior written consent, PROVIDED, HOWEVER, that if HPI or the Inventors are determined by a court to be a necessary or required party in any such suit, then no consent shall be required. If, in a suit initiated by Callisto, HPI or the Inventors are involuntarily joined other than by Callisto, or if HPI or the Inventors are joined because they are deemed to be a necessary or required party, then Callisto will pay the reasonable costs incurred by HPI or the Inventors, as applicable, arising out of such suit, including but not limited to, any reasonable legal fees of counsel that HPI or the Inventors select and retain to represent them in the suit.

ARTICLE 6 TERMINATION 6.1 TERMINATION BY HPI. (a) If Callisto materially violates any term of this Agreement, then HPI may give written notice of default ("NOTICE OF DEFAULT") to Callisto. If Callisto fails to cure the default within forty-five (45) days of the Notice of Default, HPI may terminate this Agreement and the license granted herein prior to the expiration of the Term by a second written notice ("NOTICE OF TERMINATION") to Callisto. If a Notice of Termination is sent to Callisto, this Agreement shall automatically terminate on the effective date of that notice. Termination shall not relieve Callisto of its obligation to pay any fees owed at the time of termination and shall not impair any accrued right of HPI or the Inventors. (b) If the Board of Directors of Callisto shall determine to abandon its development and commercialization efforts with respect to the 412 Patent Rights, Callisto shall notify HPI in writing within 10 days of the Board's determination and HPI shall have the right to terminate this Agreement prior to the expiration of the Term at any time upon thirty (30) days' prior written notice to Callisto. Any sublicense of the 412 Patent Rights by Callisto in accordance with the terms of this Agreement shall not trigger HPI's right to terminate this Agreement so long as under the terms of any such sublicense, Callisto retains the right to terminate such sublicense if the Sublicensee fails to use its commercially reasonable efforts to develop and commercialize at least one drug candidate resulting from the 412 Patent Rights that meets the Sublicensee's criteria for clinical development. Callisto shall promptly exercise its right to terminate if it learns that any Sublicensee of the 412 Patent Rights has failed to use its commercially reasonable efforts to develop and commercialize at least one drug candidate resulting from the 412 Patent Rights that meets the Sublicensee's criteria for clinical development and upon such termination, shall promptly provide written notice to HPI (the "NOTICE").
