Any correction in sentences?

Do the following two sentences need any correction?

(1) High levels of integration may be needed to exploit high levels of synergy, but a high level of integration may cause intense culture clash and human resource problems that can destroy the value of the acquired firm and increase costs to an extent that offsets the benefits expected from the merger.

(2) Moreover, in case of very high synergy potential, it is possible that even under the conditions of high cultural differences, which may destroy some of the synergy, M&A performance still increases.

Please help.
