          8. Indemnification.

               8.1 Right to Indemnification. The Corporation shall indemnify and

hold harmless, to the fullest extent permitted by applicable law as it presently

exists or may hereafter be amended, any person (a "Covered Person") who was or

is made or is threatened to be made a party or is otherwise involved in any

action, suit or proceeding, whether civil, criminal, administrative or

investigative (a "Proceeding"), by reason of the fact that he or she, or a

person for whom he or she is the legal representative, is or was a director or

officer of the Corporation or, while a director or officer of the Corporation,

is or was serving at the request of the Corporation as a director, officer,

employee or agent of another corporation or of a partnership, joint venture,

trust, enterprise or nonprofit entity (an "Other Entity"), including service

with respect to employee benefit plans, against all liability and loss suffered

and expenses (including attorneys' fees) reasonably



incurred by such Covered Person. Notwithstanding the preceding sentence, except

as otherwise provided in Section 8.3, the Corporation shall be required to

indemnify a Covered Person in connection with a Proceeding (or part thereof)

commenced by such Covered Person only if the commencement of such Proceeding (or

part thereof) by the Covered Person was authorized by the Board of Directors of

the Corporation (the "Board").

               8.2 Prepayment of Expenses. The Corporation shall pay the

expenses (including attorneys' fees) incurred by a Covered Person in defending

any Proceeding in advance of its final disposition, provided, however, that, to

the extent required by applicable law, such payment of expenses in advance of

the final disposition of the Proceeding shall be made only upon receipt of an

undertaking by the Covered Person to repay all amounts advanced if it should be

ultimately determined that the Covered Person is not entitled to be indemnified

under this Article 8 or otherwise.

               8.3 Claims. If a claim for indemnification or advancement of

expenses under this Article 8 is not paid in full within 30 days after a written

claim therefor by the Covered Person has been received by the Corporation, the

Covered Person may file suit to recover the unpaid amount of such claim and, if

successful in whole or in part, shall be entitled to be paid the expense of

prosecuting such claim. In any such action the Corporation shall have the burden

of proving that the Covered Person is not entitled to the requested

indemnification or advancement of expenses under applicable law.

               8.4 Nonexclusivity of Rights. The rights conferred on any Covered

Person by this Article 8 shall not be exclusive of any other rights that such



Covered Person may have or hereafter acquire under any statute, provision of

this Certificate of Incorporation, the By-laws, agreement, vote of stockholders

or disinterested directors or otherwise.

               8.5 Other Sources. The Corporation's obligation, if any, to

indemnify or to advance expenses to any Covered Person who was or is serving at

its request as a director, officer, employee or agent of an Other Entity shall

be reduced by any amount such Covered Person may collect as indemnification or

advancement of expenses from such Other Entity.

               8.6 Amendment or Repeal. Any repeal or modification of the

foregoing provisions of this Article 8 shall not adversely affect any right or

protection hereunder of any Covered Person in respect of any act or omission

occurring prior to the time of such repeal or modification.

               8.7 Other Indemnification and Prepayment of Expenses. This

Article 8 shall not limit the right of the Corporation, to the extent and in the

manner permitted by applicable law, to indemnify and to advance expenses to

persons other than Covered Persons when and as authorized by appropriate

corporate action.

          9. Adoption, Amendment and/or Repeal of By-Laws. In furtherance and

not in limitation of the powers conferred by the laws of the State of Delaware,

the Board is expressly authorized to make, alter and repeal the By-laws, subject

to the power of the stockholders of the Corporation to alter or repeal any

By-law whether adopted by them or otherwise.

          10. Certificate Amendments. The Corporation reserves the right at any

time, and from time to time, to amend, alter, change or repeal any provision

contained in

of the State of Delaware at the time in force may be added or inserted, in the

manner now or hereafter prescribed by applicable law; and all rights,

preferences and privileges of whatsoever nature conferred upon stockholders,
