      6.           Voting
Rights.  The Pledgor has classified the Pledged Securities as
“issued but not outstanding”.  However, unless and until an Event of
Default shall have occurred and be continuing, the Pledgor shall retain the
right to vote the Pledged Securities and to give consents, waivers and
ratifications in respect of the Pledged Securities to the extent same
exist.  Once an Event of Default shall have occurred and so long as it
is continuing, the Secured Party shall have the right to vote the Pledged
Securities and to give consents, waivers and ratification in respect of the
Pledged Securities.

       

      7.           Events of
Default.  The occurrence of an Event of Default under the Note
shall constitute an Event of Default hereunder.

       

      8.           Rights and Remedies Upon an
Event of Default.  If an Event of Default shall have occurred
and be continuing, subject to the receipt of all required regulatory
approvals:

       

      (a)         The
Secured Party shall, after giving written notice to the Pledgor specifying the
action to be taken, register any or all shares of the Pledged Securities held by
the Secured Party in the name of the Secured Party.

       

      (b)        
The Secured Party may demand, sue for, collect or make any compromise or
settlement the Secured Party deems suitable in respect of the Pledged Securities
held by it hereunder.

       

      (c)         The
Secured Party shall have all of the rights and remedies with respect to the
Pledged Securities of a secured party under the UCC.

       

      (d)         The
Secured Party may, upon fifteen (15) days prior written notice to the Pledgor of
the time and place, with respect to the Pledged Securities, sell, lease, assign
or otherwise dispose of all or any of such Pledged Securities, at such place or
places as the Secured Party deems best, and for cash or on credit for future
delivery (without thereby assuming any credit risk), at public or private sale,
without demand of performance or notice of intention to erect any such
disposition or of time or place thereof (except such notice as is required
hereunder or by applicable statute and cannot be waived) and the Secured Party
or anyone else may be the purchaser, lessee, assignee or recipient of any or all
of the Pledged Securities so disposed of at public sale (or, to the extent
permitted by law, at any private sale), and thereafter hold the same absolutely,
free from any claim or right of whatsoever kind, including any equity of
redemption, of the Pledgor, any such demand, notice or right and equity being
hereby expressly waived and released.  The net proceeds of any sale of
Pledged Securities pursuant to this Section 8 shall be applied first to the
repayment of the outstanding principal and accrued interest under the Note and
any reasonable costs and expenses of Secured Party (including attorney's fees,
costs and disbursements) incurred by Secured Party in enforcing its rights under
this Agreement and only after so applying such net proceeds and after such
payment need the Secured Party account for the surplus, if any, to the Pledgor,
or to whomsoever may be lawfully entitled to receive the same, or as a court of
competent jurisdiction my direct.

      9.           Private Sale and Compliance with
Law.

       

      (a)         The
Secured Party shall incur no liability as a result of the sale of the Pledged
Securities, or any part thereof, at any private sale conducted in a commercially
reasonable manner.  The Pledgor hereby waives any claim against the
Secured Party arising by reason of the fact that the price at which the Pledged
Securities may have been sold at such a private sale conducted in a commercially
reasonable manner was less than the price which might have been obtained at a
public sale or was less than the aggregate amount due under the Note, even if
the Secured Party accepts the first offer received and does not offer the
Pledged Securities to more than one offeree.

       

      (b)         The
Pledgor agrees that in any sale of any of the Pledged Securities whenever an
Event of Default shall have occurred and be continuing, the Secured Party is
hereby authorized to comply with any limitation or restriction in connection
with such sale as it may be advised by counsel is necessary in order to avoid
any violation of applicable law (including, without limitation, compliance with
such procedures as may restrict the number of prospective bidders and purchasers
or require that such prospective bidders and purchasers be persons who will
represent and agree that they are purchasing for their own account for
investment and not with a view to the distribution or resale of such Pledged
Securities), or in order to obtain any required approval of the sale or of the
purchaser by any governmental regulatory authority or official, and the Pledgor
further agrees that such compliance shall not result in such sale being
considered or deemed not to have been made in a commercially reasonable manner,
nor shall the Secured Party be liable or accountable to the Pledgor for any
discount allowed by the reason of the fact that such Pledged Securities is sold
in compliance with any such limitation or restriction.

       

      10.         Retention of
Collateral.  Notwithstanding any provision of this Agreement to
the contrary, the Secured Party may in its discretion retain all or a portion of
the Security Interest in satisfaction of any or all due and payable obligations
under the Note.  The portion of the Security Interest that may in its
discretion be retained by the Secured Party in satisfaction of such obligations
shall be that portion having a fair market value or cash value, as applicable,
equal to the amount of such obligations at the time such public or private sale
would have been held.  Such fair market value or cash value, as
applicable, shall be determined jointly by the Pledgor and the Secured Party,
and the parties hereby agree to cooperate in such determination.  In
the event that the parties are unable to agree on such fair market value or cash
value, as applicable, it shall be determined by a recognized actuarial or
accounting firm jointly selected by the Pledgor and the Secured
Party.  All expenses of such determination, including without
limitation the fees and expenses of such actuarial or accounting firm, shall he
borne by the Pledgor.

       

      11.         Further
Assurances.  The Pledgor agrees that at any time and from time
to time upon the written request of the Secured Party, it will execute and
deliver such further documents and do such further acts and things as the
Secured Party may reasonably request in order to affect the purposes of this
Agreement.

      12.         No Waiver; Cumulative
Remedies.  The Secured Party shall not by any act, delay,
omission or otherwise be deemed to have waived any of its rights or remedies
hereunder and no waiver shall be valid unless in writing, and then only to the
extent therein set forth.  A waiver by the Secured Party of any right
or remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Secured Party would otherwise have on any future
occasion.  No failure to exercise nor any delay in exercising on the
part of the Secured Party of any right, power or privilege hereunder, shall
operate as a waiver thereof by the Secured Party; nor shall any single or
partial exercise of any right, power or privilege hereunder preclude any other
or further exercise thereof or the exercise of any other right, power or
privilege.

       

      13.         Notices.  All
