	4.		Buyer understands that TWP may not be able to effect a Buy due to a market disruption or a legal, regulatory or contractual restriction applicable to TWP. If any Purchase cannot be executed as required by paragraph 1, due to a market disruption, a legal, regulatory or contractual restriction applicable to TWP or any other event, TWP shall effect such Purchase as promptly as practical after the cessation or termination of such market disruption, applicable restriction or other event.

Buyer agrees not to take any action which would cause any such purchase not to comply with the said Rule 10b-18.

	6.		Buyer represents and warrants that they are not aware of material, nonpublic information with respect to the Issuer or any securities of the Issuer (including the Stock) and is entering into this Purchase Plan in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b5-1.
