| | 2.6
Development of 125 mg Tablets:

| | (a) |  | Par
shall use commercially reasonable efforts to (i) develop doxycycline
                    mono tablets in the dosage amount of 125 mg (the 125
mg                     Tablets) for sale in the Territory and (ii) submit
to                     the FDA on or before February 1, 2007 an ANDA to obtain final
and                     unconditional approval enabling Par to sell the 125 mg Tablets in
the Territory                     (125 mg Tablets Approval);
provided, however, that, if Par is required by the FDA to perform any
pivotal                     biostudies for the 125 mg Tablets, Par, prior to initiating
such biostudies,                     shall so notify Bradley in writing (the Biostudies
Notice),                     and Bradley shall promptly reimburse Par for Pars
out-of-pocket expenses                     incurred in connection with such pivotal
biostudies, unless Bradley notifies Par                     in writing within thirty (30)
days of its receipt of the Biostudies Notice                     to discontinue
development of the 125 mg Tablets (the Notice to
                    Discontinue Development), effective from the
date of                     Pars receipt of such Notice; provided, further,
that nothing                     herein contained shall constitute a guarantee or
warranty by Par that 125 mg                     Tablets Approval will be obtained.
Subject to the foregoing, if Par shall fail                     to submit the ANDA
described in clause (ii) of this Section 2.6(a)                     within

hereof; provided, the remaining provisions of this                     Agreement,
