enter, with the aid and assistance of any person or persons, any premises where
the Collateral, or any part thereof, is, or may be, placed or assembled, and
remove any of the same;
 
c. execute any instrument and do all other things necessary and proper to
protect and preserve and realize upon such Collateral and other rights
contemplated hereby; and
 
d. without obligation to resort to other security, at any time and from time to
time, sell, assign and deliver at the same or different times, all right, title,
interest or claim of the Debtor in such Collateral, and any right of redemption
thereof, at public or private sale, in one or more parcels, for cash, upon
credit or for future delivery, and at such price or prices and on such terms as
the Holder may determine.
 
The Debtor hereby agrees that the exercise by the Holder of the rights and
remedies under this section, including, without limitation, sale of Inventory or
Equipment may be accomplished without demand, advertisement or notice (except as
required by law), all of which (to the extent permitted by law) are hereby
expressly waived. If any notice of a proposed sale or other disposition shall be
required by law, such notice shall be deemed reasonable and proper if given at
least 10 days before such sale or other disposition. The Holder shall not be
obligated to make any sale regardless of notice of sale having been given. The
Holder may adjourn any public or private sale from time to time by announcement
at the time and place fixed therefore, and such sale may, without further
notice, be made at the time and place to which it was so adjourned.
 

--------------------------------------------------------------------------------

The Holder may offer any Inventory or Equipment for sale in its then present
condition and has no duty to repair or clean the Collateral prior to sale and
the failure to make such repairs or clean the Collateral shall not effect the
commercial reasonableness of the sale. The Holder may disclaim all warranties
including warranties of title, possession, quiet enjoyment, merchantability,
fitness for a particular and any such disclaimer shall not effect the commercial
reasonableness of the sale. The Holder shall not be obligated to take any of the
action authorized by this section, but in the event that the Holder elects to
take any such action, it shall not be responsible to the Debtor except for its
willful misconduct.
 
5.05 As to Instruments, Chattel Paper and Investment Property
 
During the existence of an Event of Default, subject to the prior rights of any
other holders of Permitted Liens:
 
a. if the Holder shall so request, the Debtor shall forthwith do one or more of
the following: (i) legend, in form and manner acceptable to the Holder, the
Debtor’s books, records and documents evidencing or pertaining to any
Instruments, Chattel Paper or Investment Property with an appropriate reference
to the fact that such assets have been assigned to the Holder and that the
Holder has a security interest therein and notify any person with an obligation
with respect to such Collateral of the Holder’s security interest therein, (ii)
account for and transmit to the Holder, in the same form as received, all
proceeds of collection of such Collateral received by it and, until so
transmitted, to hold the same in trust for the Holder and not commingle such
proceeds with any other of its funds, (iii) deliver, at its own expense, any or
all books, records or other documents relating to such Collateral to the Holder
at a place designated by the Holder, and (iv) notify the obligors on such
Collateral that such assets have been assigned to the Holder and that payments
in respect thereof shall be made directly to the Holder.
 
b. the Holder, without notice to, or assent by, the Debtor and in the name of
the Debtor or its own name, or otherwise, may (but need not) (i) notify the
obligors of any of the Debtor’s Instruments, Chattel Paper or Investment
Property to make payments thereon directly to the Holder; (ii) ask for, demand,
collect, receive, compound and give acceptance for the such Collateral or any
part thereof; (iii) extend the time of payment for such Collateral or compromise
or settle any such Collateral for cash, credit or otherwise, and upon any terms
and conditions; (iv) endorse the name of the Debtor on any check, draft or other
order or instrument for the payment of moneys payable to the Debtor which has
been issued in respect of such Collateral; (v) file any claims and commence,
maintain or discontinue any action, suits or other proceedings deemed by the
Holder necessary or advisable for the purpose of collecting or enforcing payment
of any such Collateral; (vi) at the Holder’s sole discretion make test
verifications of such Collateral or any portion thereof; (vii) execute any
instrument and do any and all other things necessary and proper to protect and
preserve and realize upon such Collateral and other rights contemplated hereby;
and (viii) without obligation to resort to other security, at any time and from
time to time, sell, re-sell, assign and deliver all or any such Collateral, in
one or more parcels at the same or different times, and all right, title and
interest, claim and demand therein and any right of redemption thereof, at
public or private sale, for cash, upon credit or for future delivery and at such
price or prices and on such terms as the Holder may determine, with the proceeds
thereof to be applied in the manner provided herein.
 
 

--------------------------------------------------------------------------------

 
 
The Debtor hereby agrees that the Holder may sell such Collateral or any part
thereof at public or private sale or at any broker's board or on any securities
exchange, for cash, upon credit or for future delivery, and at such price or
prices as the Holder may deem satisfactory. The Holder may be the purchaser of
any or all of the Collateral so sold at any public sale. The Debtor covenants
and agrees that it will execute and deliver such documents and take such other
action as the Holder deems necessary or advisable in order that any such sale
may be made in compliance with law. Upon any such sale the Holder shall have the
right to deliver, assign and transfer to the purchaser thereof the Collateral so
sold. Each purchaser at any such sale shall hold the Collateral so sold
absolutely and free from any claim or right of whatsoever kind, including any
equity or right of redemption of the Debtor which may be waived, and the Debtor,
to the extent permitted by law, hereby specifically waives all rights of
redemption, stay or appraisal which it has or may have under any law now
existing or hereafter adopted. The Debtor further acknowledges that the Holder
may deem it impracticable to effect a public sale of any part of the securities
included in the Collateral, and therefore authorizes the Holder in connection
with any such private sale, if the Holder deems it advisable to do so, (i) to
restrict the prospective bidders on or purchasers of any of the Collateral to a
limited number of sophisticated investors who will represent and agree that they
are purchasing for their own account for investment and not with a view to the
distribution or sale of any of such securities, (ii) to cause to be placed on
certificates for any or all of the Collateral or on any other securities pledged
hereunder a legend to the effect that such security has not been registered
under the Securities Act of 1933 and may not be disposed of in violation of the
provision of said Act, and (iii) to impose such other limitations or conditions
in connection with any such sale as the Holder deems necessary or advisable in
order to comply with said Act or any other law. The notice (if any) of such sale
shall (1) in case of a public sale, state the time and place fixed for such
sale, (2) in case of sale at a broker's board or on a securities exchange, state
the board or exchange at which such sale is to be made and the day on which the
Collateral, or the portion thereof so being sold, will first be offered for sale
at such board or exchange, and (3) in the case of a private sale, state the day
after which such sale may be consummated. Any such public sale shall be held at
such time or times within ordinary business hours and at such place or places as
the Holder may fix in the notice of such sale. At any such sale, the Collateral
may be sold in one lot as an entirety or in separate parcels, as the Holder may
determine. The Holder shall not be obligated to make any such sale pursuant to
any such notice. The Holder may, without notice or publication, adjourn any
public or private sale or cause the same to be adjourned from time to time by
announcement at the time and place fixed for the sale, and such sale may be made
at any time or place to which the same may be so adjourned. In case of any sale
of all or any part of the Collateral on credit or for future delivery, the
Collateral so sold may be retained by the Holder until the selling price is paid
by the purchaser thereof, but the Holder shall not incur any liability in case
of the failure of such purchaser to take up and pay for the Collateral so sold
and, in case of any such failure, such Collateral may again be sold upon like
notice.

5.06 Application of Proceeds; Deficiency
 
a. The Holder shall apply the net proceeds of any such collection, realization
or sale, after deducting all reasonable costs and expenses of every kind
incurred thereinor incidental to the care or safekeeping of any of the
Collateral or in any way relating to the Collateral or the rights of the Holder
hereunder, including, without limitation, reasonable attorneys’ fees and
disbursements, to the payment in whole or in part of the Secured Obligations pro
rata in proportion to the amounts owed to each of the holders, and only after
such application and after the payment by the Holder of any other amount
required by any provision of law, need the Holder account for the surplus, if
any, to the Debtor.
 
 
 

--------------------------------------------------------------------------------

 
b. The Debtor shall remain liable for any deficiency if the proceeds of any sale
or other disposition of the Collateral are insufficient to pay the Secured
Obligations and the reasonable fees and disbursements of any attorneys employed
by the Holder to collect such deficiency.

the case of any waiver, the Debtor shall be restored to its former positions and

exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges herein provided to the Holder are cumulative and not

date and then only until such Event of Default has been cured (the “Termination
Date”). The Holder hereby irrevocably constitutes and appoints Debtor and any
officer or agent thereof, with full power of substitution, as its true and
lawful attorney-in-fact with full irrevocable power and authority in place and
stead of the Holder and in the name of the Holder or in its own name,

Holder harmless from, any and all liabilities, costs and expenses (including,
without limitation, reasonable legal fees and expenses) (a) with respect to, or
resulting from, any delay in paying, any and all excise, sales or other taxes
which may be payable or determined to be payable with respect to any of the
Collateral, except in connection with any costs resulting from the gross
negligence or willful misconduct of the Holder, or (b) with respect to, or
resulting from, any delay in complying with any Requirement of Law applicable to
any of the Collateral, except in connection with any costs resulting from the
gross negligence or willful misconduct of the Holder. In any suit, proceeding or
action brought by the Holder under any Account for any sum owing thereunder, or
to enforce any provisions of any Account, the Debtor will save, indemnify and
keep the Holder harmless from and against all expense, loss or damage suffered
by reason of any defense, set-off, counterclaim, recoupment or reduction or
liability whatsoever of the account debtor or obligor thereunder, arising out of
a breach by the Debtor of any obligation thereunder or arising out of any other
agreement, indebtedness or liability at any time owing to or in favor or such
account debtor or obligor or its successors.
