Entropin agrees to reimburse WCCS for its reasonable out of pocket expenses incurred in connection with such cooperation. Notwithstanding the condition set forth at the beginning of this paragraph, Entropin agrees that so long as WCCS provides the written explanation contemplated in Section 2.2, the absence of any Confidential Information will not be a basis for non-payment of the consideration to be received by WCCS under this Agreement, nor shall it constitute a claim by Entropin under the Carve Out as defined in Section 6.1 of this Agreement.
