Corp. Code, § 9632

Any deed or instrument conveying or otherwise transferring any assets of a corporation may have annexed to it the certificate of the secretary or an assistant secretary of the corporation, setting forth that the transaction has been validly approved by the board, that the notice, if any, required by Section 9633 has been given and (a) stating that the property described in such deed or instrument is less than substantially all of the assets of the corporation or that the transfer is in the usual and regular course of the business of the corporation, if such be the case, or (b) if such property constitutes all or substantially all of the assets of the corporation and the transfer is not in the usual and regular course of the business of the corporation, stating the fact of approval thereof by the members (Section 5034). Such certificate is prima facie evidence of the existence of the facts authorizing such conveyance or other transfer of the assets and conclusive evidence in favor of any purchaser or encumbrancer for value who, without notice of any trust restriction applicable to the property or any failure to comply therewith, in good faith parted with value.
