judgments, fines and amounts paid in settlements actually and reasonably incurred by them in connection with any action, suit or proceeding brought by third parties, if such directors or officers acted in good faith and in a manner they reasonably
believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, if they had no reasonable cause to believe their conduct was unlawful. In an action by or in the right of the
corporation, indemnification may be made only for expenses actually and reasonably incurred by directors and officers in connection with the defense or settlement of an action or suit, and only with respect to a matter as to which they shall have
acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made if such person shall have been adjudged liable to the corporation, although
the court in which the action or suit was brought or the Delaware Court of Chancery may determine upon application that the defendant officers or directors are reasonably entitled to indemnity for such expenses despite such adjudication of
liability. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify the officer or director against the expenses that such officer or director actually and
reasonably incurred. Section&nbsp;145 of the DGCL also provides that expenses (including attorneys&#146; fees) incurred by an officer or director of the corporation in defending any civil, criminal, administrative or investigative action, suit or
proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined
that such person is not entitled to be indemnified by the corporation. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The registrant has entered into indemnification agreements with each of its
directors and executive officers. These agreements, among other things, require the registrant to indemnify each director and officer to the fullest extent permitted by applicable law, including indemnification for expenses such as attorneys&#146;
fees and fees of experts, witnesses, private investigators and professional advisors as well as for liabilities such as judgments, damages, losses, penalties, taxes, fines and settlement amounts incurred by the director or officer in any action or
proceeding, including any action by or in the right of the registrant, arising out of the person&#146;s services as a director or officer of the registrant or of any entity to which the person provides services at the registrant&#146;s request,
including the registrant&#146;s subsidiaries, or acting as a fiduciary with respect to its employee benefit plans. The registrant also maintains insurance coverage related to certain liabilities of directors and officers. At present, the registrant
is not aware of any pending or threatened litigation or proceeding involving any of its directors, officers, employees or agents in which indemnification would be required or permitted. The registrant believes that its charter provisions and
indemnification agreements are necessary to attract and retain qualified persons as directors and officers. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Item&nbsp;7. Exemption from Registration

policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer
or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the

authorize payroll deductions as the means of making Contributions by completing and delivering to the Company, within the time specified in the Offering, an enrollment form provided by the Company. The enrollment form will specify the amount of
Contributions not to exceed the maximum amount specified by the Committee. Each Participant&#146;s Contributions will be credited to a bookkeeping account for such Participant under the Plan and will be deposited with the general funds of the
Company except where Applicable Law requires that Contributions be deposited with a third party. If permitted in the Offering, a Participant may begin such Contributions with the first practicable payroll occurring on or after the Offering Date (or,
in the case of a payroll date that occurs after the end of the prior Offering but before the Offering Date of the next new Offering, Contributions from such payroll will be included in the new Offering). If permitted in the Offering or required by
Applicable Law, a Participant may thereafter reduce (including to zero) or increase his or her Contributions. If specifically provided in the Offering, in addition to or instead of making Contributions by payroll deductions, a Participant may make
Contributions through the payment by cash or check prior to a Purchase Date or such other payment method specified by the Committee for such Offering. </P>

Company will distribute as soon as practicable to such Participant all of his or her accumulated but unused Contributions and such Participant&#146;s Purchase Right in that Offering shall thereupon terminate. A Participant&#146;s withdrawal from
that Offering will have no effect upon his or her eligibility to participate in any other Offerings under the Plan, but such Participant will be required to deliver a new enrollment form to participate in subsequent Offerings. </P>
