hereby does, release Tvia from any and all liabilities related to such action
(excluding any liabilities Tvia may have pursuant to Section 9.1(c): (b) Oak
Technology shall bear all the expenses related to bringing such action; and (c)
Oak Technology agrees to keep Tvia reasonably informed of the status of such
action. Tvia shall, in any event, retain its right to bring an action against
such Sub-licensee or Customer for such Sub-Licensee's or Customer's breach of
any other obligations under the Sublicense Agreement, including without
limitation breach of obligations with respect to Licensee Products. If each
