REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
ACT") OR ANY OTHER APPLICABLE SECURITIES LAWS IN RELIANCE UPON AN EXEMPTION
FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH OTHER
SECURITIES LAWS. NEITHER THIS WARRANT NOR THE SHARES ISSUABLE UPON EXERCISE
HEREOF MAY BE SOLD, PLEDGED, TRANSFERRED, ENCUMBERED OR OTHERWISE DISPOSED OF

                             STOCK PURCHASE WARRANT

                  To Purchase 120,000 Shares of Common Stock of

                          NHANCEMENT TECHNOLOGIES INC.

                  THIS CERTIFIES that, for value received, Kedrick Investments
Limited (the "Holder"), is entitled, upon the terms and subject to the
conditions hereinafter set forth, at any time on or after May 23, 2000 (the
"Issuance Date") and on or prior to the close of business on May 23, 2003 (the
"Termination Date") but not thereafter, to subscribe for and purchase from
NHancement Technologies Inc., a Delaware corporation (the "Company"), up to one
hundred twenty thousand (120,000) shares (the "Warrant Shares") of Common Stock,
$.01 par value, of the Company (the "Common Stock"). The purchase price of one
share of Common Stock (the "Exercise Price") under this Warrant shall be $20.82.
The Exercise Price and the number of shares for which the Warrant is exercisable
shall be subject to adjustment as provided herein. In the event of any conflict
between the terms of this Warrant and the Common Stock Purchase Agreement dated
May 23, 2000 pursuant to which this Warrant has been issued (the "Purchase
Agreement"), the Purchase Agreement shall control. Capitalized terms used and
not otherwise defined herein shall have the meanings set forth for such terms in
the Purchase Agreement.

                  1. TITLE TO WARRANT. Prior to the Termination Date hereof and
subject to compliance with applicable laws, this Warrant and all rights
hereunder are transferable, in whole or in part, at the office or agency of the
Company by the holder hereof in person or by duly authorized attorney, upon
surrender of this Warrant together with the Assignment Form annexed hereto
properly endorsed.

                  2. AUTHORIZATION OF SHARES. The Company covenants that all
shares of Common Stock which may be issued upon the exercise of rights
represented by this Warrant will, upon exercise of the rights represented by
this Warrant, be duly authorized, validly issued, fully paid and
nonassessable and free from all taxes, liens and charges in respect of the
issue

                                       1

<PAGE>

thereof (other than taxes in respect of any transfer occurring
contemporaneously with such issue).

                  3. EXERCISE OF WARRANT. Except as provided in Section 4
herein, exercise of the purchase rights represented by this Warrant may be
made at any time or times on or after the Issuance Date hereof and before the
close of business on the Termination Date hereof. Exercise of this Warrant or
any part hereof shall be effected by the surrender of this Warrant and the
Notice of Exercise Form annexed hereto duly executed, at the office of the
Company (or such other office or agency of the Company as it may designate by
notice in writing to the registered holder hereof at the address of such
holder appearing on the books of the Company) and upon payment of the
Exercise Price of the shares thereby purchased by wire transfer or cashier's
check drawn on a United States bank, the holder of this Warrant shall be
entitled to receive a certificate for the number of shares of Common Stock so
purchased. Certificates for shares purchased hereunder shall be delivered to
the holder hereof within three (3) Trading Days after the date on which this
Warrant shall have been exercised as aforesaid. This Warrant shall be deemed
to have been exercised and such certificate or certificates shall be deemed
to have been issued, and Holder or any other person so designated to be named
therein shall be deemed to have become a holder of record of such shares for
all purposes, as of the date the Warrant has been exercised by payment to the
Company of the Exercise Price and all taxes required to be paid by Holder, if
any, pursuant to Section 5 prior to the issuance of such shares, have been
paid. If this Warrant shall have been exercised in part, the Company shall,
at the time of delivery of the certificate or certificates representing
Warrant Shares, deliver to Holder a new Warrant evidencing the rights of
Holder to purchase the unpurchased shares of Common Stock called for by this
Warrant, which new Warrant shall in all other respects be identical with this
Warrant. This Warrant may also be exercised by means of a "cashless exercise"
upon surrender of this Warrant and the Notice of Cashless Exercise Form
annexed hereto duly executed, at the office of the Company (or such other
office or agency of the Company as it may designate by notice in writing to
the registered holder hereof at the address of such holder appearing on the
books of the Company), in which the holder shall be entitled to receive a
certificate for the number of shares equal to the quotient obtained by
dividing [(A-B) (X)] by (A), where:

(A) = the average of the high and low trading prices per share of Common Stock
on the Trading Day preceding the date of such election;

(B) = the Exercise Price of the Warrants; and

(X) = the number of shares issuable upon exercise of the Warrants in accordance
with the terms of this Warrant.

                  4. NO FRACTIONAL SHARES OR SCRIP. No fractional shares or
scrip representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to the Exercise Price.

                  5. CHARGES, TAXES AND EXPENSES. Issuance of certificates for
shares of Common Stock upon the exercise of this Warrant shall be made without
charge to the holder hereof for any issue or transfer tax or other incidental
expense in respect of the issuance of such

                                      2

<PAGE>

certificate, all of which taxes and expenses shall be paid by the Company,
and such certificates shall be issued in the name of the holder of this
Warrant or in such name or names as may be directed by the holder of this
Warrant; provided, however, that in the event certificates for shares of
Common Stock are to be issued in a name other than the name of the holder of
this Warrant, this Warrant when surrendered for exercise shall be accompanied
by the Assignment Form attached hereto duly executed by the holder hereof;
and the Company may require, as a condition thereto, the payment of a sum
sufficient to reimburse it for any transfer tax incidental thereto.

                  6. CLOSING OF BOOKS. The Company will not close its
shareholder books or records in any manner which prevents the timely exercise of
this Warrant.

                  7. TRANSFER, DIVISION AND COMBINATION. (a) Subject to
compliance with any applicable securities laws, transfer of this Warrant and all
rights hereunder, in whole or in part, shall be registered on the books of the
Company to be maintained for such purpose, upon surrender of this Warrant at the
principal office of the Company, together with a written assignment of this
Warrant substantially in the form attached hereto duly executed by Holder or its
agent or attorney and funds sufficient to pay any transfer taxes payable upon
the making of such transfer. Upon such surrender and, if required, such payment,
the Company shall execute and deliver a new Warrant or Warrants in the name of
the assignee or assignees and in the denomination or denominations specified in
such instrument of assignment, and shall issue to the assignor a new Warrant
evidencing the portion of this Warrant not so assigned, and this Warrant shall
promptly be cancelled. A Warrant, if properly assigned, may be exercised by a
new holder for the purchase of shares of Common Stock without having a new
Warrant issued.

                     (b)      This Warrant may be divided or combined with
other Warrants upon presentation hereof at the aforesaid office of the
Company, together with a written notice specifying the names and
denominations in which new Warrants are to be issued, signed by Holder or its
agent or attorney. Subject to compliance with Section 7(a), as to any
transfer which may be involved in such division or combination, the Company
shall execute and deliver a new Warrant or Warrants in exchange for the
Warrant or Warrants to be divided or combined in accordance with such notice.

                     (c)      The Company shall prepare, issue and deliver at
its own expense (other than transfer taxes) the new Warrant or Warrants under
this Section 7.

                     (d)      The Company agrees to maintain, at its
aforesaid office, books for the registration and the registration of transfer
of the Warrants.

                  8. NO RIGHTS AS SHAREHOLDER UNTIL EXERCISE. This Warrant
does not entitle the holder hereof to any voting rights or other rights as a
shareholder of the Company prior to the exercise hereof. Upon the surrender
of this Warrant and the payment of the aggregate Exercise Price, the Warrant
Shares so purchased shall be and be deemed to be issued to such holder as the
record owner of such shares as of the close of business on the later of the
date of such surrender or payment.

                  9. LOSS, THEFT, DESTRUCTION OR MUTILATION OF WARRANT. The
Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss,

                                      3

<PAGE>

theft, destruction or mutilation of this Warrant certificate or any stock
certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which
shall not include the posting of any bond), and upon surrender and
cancellation of such Warrant or stock certificate, if mutilated, the Company
will make and deliver a new Warrant or stock certificate of like tenor and
dated as of such cancellation, in lieu of such Warrant or stock certificate.

                  10. SATURDAYS, SUNDAYS, HOLIDAYS, ETC. If the last or
appointed day for the taking of any action or the expiration of any right
required or granted herein shall be a Saturday, Sunday or a legal holiday, then
such action may be taken or such right may be exercised on the next succeeding
day not a Saturday, Sunday or legal holiday.

                  11. ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF WARRANT
SHARES. (a) STOCK SPLITS, ETC. The number and kind of securities purchasable
upon the exercise of this Warrant and the Exercise Price shall be subject to
adjustment from time to time upon the happening of any of the following. In case
the Company shall (i) pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock to holders of its outstanding Common
Stock, (ii) subdivide its outstanding shares of Common Stock into a greater
number of shares of Common Stock, (iii) combine its outstanding shares of Common
Stock into a smaller number of shares of Common Stock or (iv) issue any shares
of its capital stock in a reclassification of the Common Stock, then the number
of Warrant Shares purchasable upon exercise of this Warrant immediately prior
thereto shall be adjusted so that the holder of this Warrant shall be entitled
to receive the kind and number of Warrant Shares or other securities of the
Company which he would have owned or have been entitled to receive had such
Warrant been exercised in advance thereof. Upon each such adjustment of the kind
and number of Warrant Shares or other securities of the Company which are
purchasable hereunder, the holder of this Warrant shall thereafter be entitled
to purchase the number of Warrant Shares or other securities resulting from such
adjustment at an Exercise Price per Warrant Share or other security obtained by
multiplying the Exercise Price in effect immediately prior to such adjustment by
the number of Warrant Shares purchasable pursuant hereto immediately prior to
such adjustment and dividing by the number of Warrant Shares or other securities
of the Company resulting from such adjustment. An adjustment made pursuant to
this paragraph shall become effective immediately after the effective date of
such event retroactive to the record date, if any, for such event.

                      (b) REORGANIZATION, RECLASSIFICATION, MERGER,
CONSOLIDATION OR DISPOSITION OF ASSETS. In case the Company shall reorganize
its capital, reclassify its capital stock, consolidate or merge with or into
another corporation (where the Company is not the surviving corporation or
where there is a change in or distribution with respect to the Common Stock
of the Company), or sell, transfer or otherwise dispose of all or
substantially all its property, assets or business to another corporation
and, pursuant to the terms of such reorganization, reclassification, merger,
consolidation or disposition of assets, shares of common stock of the
successor or acquiring corporation, or any cash, shares of stock or other
securities or property of any nature whatsoever (including warrants or other
subscription or purchase rights) in addition to or in lieu of common stock of
the successor or acquiring corporation ("Other Property"), are to be received
by or distributed to the holders of Common Stock of the Company, then Holder
shall have the right thereafter to receive, upon exercise of this Warrant,
the number of shares of common stock of the successor or acquiring
corporation or of the Company, if it is the surviving

                                      4
<PAGE>

corporation, and Other Property receivable upon or as a result of such
reorganization, reclassification, merger, consolidation or disposition of
assets by a holder of the number of shares of Common Stock for which this
Warrant is exercisable immediately prior to such event. In case of any such
reorganization, reclassification, merger, consolidation or disposition of
assets, the successor or acquiring corporation (if other than the Company)
shall expressly assume the due and punctual observance and performance of
each and every covenant and condition of this Warrant to be performed and
observed by the Company and all the obligations and liabilities hereunder,
subject to such modifications as may be deemed appropriate (as determined in
good faith by resolution of the Board of Directors of the Company) in order
to provide for adjustments of shares of Common Stock for which this Warrant
is exercisable which shall be as nearly equivalent as practicable to the
adjustments provided for in this Section 11. For purposes of this Section 11,
"common stock of the successor or acquiring corporation" shall include stock
of such corporation of any class which is not preferred as to dividends or
assets over any other class of stock of such corporation and which is not
subject to redemption and shall also include any evidences of indebtedness,
shares of stock or other securities which are convertible into or
exchangeable for any such stock, either immediately or upon the arrival of a
specified date or the happening of a specified event and any warrants or
other rights to subscribe for or purchase any such stock. The foregoing
provisions of this Section 11 shall similarly apply to successive
reorganizations, reclassifications, mergers, consolidations or disposition of
assets.

                  12. VOLUNTARY ADJUSTMENT BY THE COMPANY. The Company may at
any time during the term of this Warrant, reduce the then current Exercise Price
to any amount and for any period of time deemed appropriate by the Board of
Directors of the Company.

                  13. NOTICE OF ADJUSTMENT. Whenever the number of Warrant
Shares or number or kind of securities or other property purchasable upon the
exercise of this Warrant or the Exercise Price is adjusted, as herein provided,
the Company shall promptly mail by registered or certified mail, return receipt
requested, to the holder of this Warrant notice of such adjustment or
adjustments setting forth the number of Warrant Shares (and other securities or
property) purchasable upon the exercise of this Warrant and the Exercise Price
of such Warrant Shares (and other securities or property) after such adjustment,
setting forth a brief statement of the facts requiring such adjustment and
setting forth the computation by which such adjustment was made. Such notice, in
the absence of manifest error, shall be conclusive evidence of the correctness
of such adjustment.

                  14. NOTICE OF CORPORATE ACTION. If at any time:

                      (a)      the Company shall take a record of the holders
of its Common Stock for the purpose of entitling them to receive a dividend
or other distribution, or any right to subscribe for or purchase any
evidences of its indebtedness, any shares of stock of any class or any other
securities or property, or to receive any other right, or

                      (b)      there shall be any capital reorganization of
the Company, any reclassification or recapitalization of the capital stock of
the Company or any consolidation or merger of the Company with, or any sale,
transfer or other disposition of all or substantially all the property,
assets or business of the Company to, another corporation or,

                                      5

<PAGE>

                      (c)      there shall be a voluntary or involuntary
dissolution, liquidation or winding up of the Company;

then, in any one or more of such cases, the Company shall give to Holder (i)
at least 30 days' prior written notice of the date on which a record date
shall be selected for such dividend, distribution or right or for determining
rights to vote in respect of any such reorganization, reclassification,
merger, consolidation, sale, transfer, disposition, liquidation or winding
up, and (ii) in the case of any such reorganization, reclassification,
merger, consolidation, sale, transfer, disposition, dissolution, liquidation
or winding up, at least 30 days' prior written notice of the date when the
same shall take place. Such notice in accordance with the foregoing clause
also shall specify (i) the date on which any such record is to be taken for
the purpose of such dividend, distribution or right, the date on which the
holders of Common Stock shall be entitled to any such dividend, distribution
or right, and the amount and character thereof, and (ii) the date on which
any such reorganization, reclassification, merger, consolidation, sale,
transfer, disposition, dissolution, liquidation or winding up is to take
place and the time, if any such time is to be fixed, as of which the holders
of Common Stock shall be entitled to exchange their shares of Common Stock
for securities or other property deliverable upon such disposition,
dissolution, liquidation or winding up. Each such written notice shall be
sufficiently given if addressed to Holder at the last address of Holder
appearing on the books of the Company and delivered in accordance with
Section 16(d).

                  15. AUTHORIZED SHARES. The Company covenants that during the
period the Warrant is outstanding, it will reserve from its authorized and
unissued Common Stock a sufficient number of shares to provide for the issuance
of the Warrant Shares upon the exercise of any purchase rights under this
Warrant. The Company further covenants that its issuance of this Warrant shall
constitute full authority to its officers who are charged with the duty of
executing stock certificates to execute and issue the necessary certificates for
the Warrant Shares upon the exercise of the purchase rights under this Warrant.
The Company will take all such reasonable action as may be necessary to assure
that such Warrant Shares may be issued as provided herein without violation of
any applicable law or regulation, or of any requirements of the Principal Market
upon which the Common Stock may be listed.

                      The Company shall not by any action, including,
without limitation, amending its certificate of incorporation or through
any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or any other voluntary action, avoid or seek to
avoid the observance or performance of any of the terms of this Warrant, but
will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of Holder against impairment. Without limiting the
generality of the foregoing, the Company will (a) not increase the par value
of any shares of Common Stock receivable upon the exercise of this Warrant
above the amount payable therefor upon such exercise immediately prior to
such increase in par value, (b) take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully
paid and nonassessable shares of Common Stock upon the exercise of this
Warrant, and (c) use all commercially reasonable efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having
jurisdiction thereof as may be necessary to enable the Company to perform its
obligations under this Warrant.

                                      6
<PAGE>

                           Upon the request of Holder, the Company will
at any time during the period this Warrant is outstanding acknowledge in
writing, in form reasonably satisfactory to Holder, the continuing validity
of this Warrant and the obligations of the Company hereunder.

                           Before taking any action which would cause an
adjustment reducing the current Exercise Price below the then par value, if
any, of the shares of Common Stock issuable upon exercise of the Warrants,
the Company shall take any corporate action which may be necessary in order
that the Company may validly and legally issue fully paid and non-assessable
shares of such Common Stock at such adjusted Exercise Price.

                           Before  taking any action  which would result in
an adjustment in the number of shares of Common Stock for which this
Warrant is exercisable or in the Exercise Price, the Company shall obtain all
such authorizations or exemptions thereof, or consents thereto, as may be
necessary from any public regulatory body or bodies having jurisdiction
thereof.

                  16.      MISCELLANEOUS.

                           (a)      JURISDICTION. This Warrant shall be
binding upon any successors or assigns of the Company. This Warrant shall
constitute a contract under the laws of New York without regard to its
conflict of law principles or rules, and be subject to arbitration pursuant
to the terms set forth in the Purchase Agreement.

                           (b)      RESTRICTIONS. The holder hereof
acknowledges that the Warrant Shares acquired upon the exercise of this
Warrant, if not registered, will have restrictions upon resale imposed by
state and federal securities laws.

                           (c)      NONWAIVER AND EXPENSES. No course of
dealing or any delay or failure to exercise any right hereunder on the
part of Holder shall operate as a waiver of such right or otherwise prejudice
Holder's rights, powers or remedies, notwithstanding all rights hereunder
terminate on the Termination Date hereof. If the Company willfully fails to
comply with any material provision of this Warrant, the Company shall pay to
Holder such amounts as shall be sufficient to cover any costs and expenses
including, but not limited to, reasonable attorneys' fees, including those of
appellate proceedings, incurred by Holder in collecting any amounts due
pursuant hereto or in otherwise enforcing any of its rights, powers or
remedies hereunder.

                           (d)      NOTICES. Any notice, request or other
document required or permitted to be given or delivered to the holder
hereof by the Company shall be delivered in accordance with the notice
provisions of the Purchase Agreement.

                           (e)      LIMITATION OF LIABILITY. No provision
hereof, in the absence of affirmative action by Holder to purchase shares
of Common Stock, and no enumeration herein of the rights or privileges of
Holder hereof, shall give rise to any liability of Holder for the purchase
price of any Common Stock or as a stockholder of the Company, whether such
liability is asserted by the Company or by creditors of the Company.

                                      7

<PAGE>

                           (f)      REMEDIES. Holder, in addition to
being entitled to exercise all rights granted by law, including recovery
of damages, will be entitled to specific performance of its rights under this
Warrant. The Company agrees that monetary damages would not be adequate
compensation for any loss incurred by reason of a breach by it of the
provisions of this Warrant and hereby agrees to waive the defense in any
action for specific performance that a remedy at law would be adequate.

                           (g)      SUCCESSORS AND ASSIGNS. Subject to
applicable securities laws, this Warrant and the rights and obligations
evidenced hereby shall inure to the benefit of and be binding upon the
successors of the Company and the successors and permitted assigns of Holder.
The provisions of this Warrant are intended to be for the benefit of all
Holders from time to time of this Warrant and shall be enforceable by any
such Holder or holder of Warrant Shares.

                           (h)      AMENDMENT. This Warrant may be modified
or amended or the provisions hereof waived with the written consent of the
Company and the Holder.

                           (i)      SEVERABILITY. Wherever possible, each
provision of this Warrant shall be interpreted in such manner as to be
effective and valid under applicable law, but if any provision of this
Warrant shall be prohibited by or invalid under applicable law, such
provision shall be ineffective to the extent of such prohibition or
invalidity, without invalidating the remainder of such provisions or the
remaining provisions of this Warrant.

                           (j)      HEADINGS. The headings used in this
Warrant are for the convenience of reference only and shall not, for any
purpose, be deemed a part of this Warrant.

                                  Exhibit 10.59

                       MASTER AGREEMENT TO LEASE EQUIPMENT

         THIS MASTER AGREEMENT TO LEASE EQUIPMENT (this "AGREEMENT") is entered
into as of April 21, 2000 by and between CISCO SYSTEMS CAPITAL CORPORATION
("LESSOR"), having its principal place of business at 170 West Tasman Drive,
Mailstop SJC2, 3rd Floor, San Jose, California 95134 and NHANCEMENT TECHNOLOGIES
INC., a Delaware Corporation ("LESSEE"), having its principal place of business
at 6663 Owens Drive, Pleasanton, CA 94588.

                                  I. THE LEASE

         1.1 LEASE OF EQUIPMENT. In accordance with the terms and conditions of
this Agreement, Lessor shall lease to Lessee, and Lessee shall lease from
Lessor, the personal property described in the lease schedule(s) (each, a
"SCHEDULE") to be entered into from time to time into which this Agreement is
incorporated (each Schedule, together with this Agreement, a "LEASE"), together
with all substitutions, replacements, repairs, parts and attachments,
improvements and accessions thereto (the "EQUIPMENT"). Capitalized terms not
otherwise defined in this Agreement have the meanings specified in the
applicable Schedule. Each Lease shall constitute a separate, distinct, and
independent lease and contractual obligation of Lessee. Except as expressly set
forth in any Lease, Lessor shall at all times retain the full legal title to the
Equipment, it being expressly agreed by both parties that each Lease is an
agreement of lease only.

         1.2 EQUIPMENT PROCUREMENT. Lessee has ordered or shall order the
Equipment pursuant to one or more purchase orders or purchase contracts
(together, "PURCHASE ORDER") to or with Cisco Systems, Inc., or a Cisco-approved
reseller (together, "VENDOR"), which Purchase Order shall be promptly delivered
to Lessor. Subject to Lessor's acceptance of such Equipment, as evidenced by its
preparation and delivery to Lessee for signature of a Schedule relating to such
Equipment, Lessee shall be deemed to have assigned to Lessor all Lessee's right,
title and interest in and to the Equipment and the Purchase Order; provided that
Lessor shall have no obligations under the Purchase Order. Lessee shall execute
and return to Lessor (a) each Schedule within five days of Lessee's receipt of
same, and (b) each Certificate of Acceptance within five days of receipt and
acceptance of the applicable Equipment. If for whatever reason the lease
transaction in respect of the Equipment is not consummated, (i) Lessee shall
remain solely liable to pay Vendor in accordance with the Purchase Order, and
(ii) upon receipt of satisfactory evidence of such payment by Lessee, Lessor
shall assign to Lessee, without warranty, its right, title and interest in and
to the Equipment and the Purchase Order.

         1.3 TERM OF LEASE. The Original Term of each Lease shall begin on the
Commencement Date as specified in the applicable Schedule and, subject to
Sections 3.5 and

                                       1.
<PAGE>

4.2, shall terminate on the date specified in the applicable Schedule. If so
provided in the applicable Schedule, the Original Term for any Lease may be
succeeded by one or more Extended Terms. Subject to Sections 3.5 and 4.2 and any
express provisions of the Schedule, no Lease may be terminated by Lessor or
Lessee, for any reason whatsoever, prior to the end of the Original Term or any
pending Extended Term.

         1.4 RENTAL PAYMENTS. Lessee shall pay Lessor Rent for the Equipment in
the amounts and at the times specified in the applicable Schedule. All Rent and
other amounts payable by Lessee to Lessor hereunder shall be paid to Lessor at
the address specified above, or at such other place as Lessor may designate in
writing to Lessee from time to time.

         1.5 RETURN OF EQUIPMENT. Upon expiration of the Lease Term, Lessee
shall immediately return the Equipment to Lessor in the condition and at the
place provided in Section 3.3.

              II. DISCLAIMERS AND WARRANTIES; INTELLECTUAL PROPERTY

         2.1 DISCLAIMERS; WARRANTIES. Lessee represents and acknowledges that
the Equipment is of a size, design, capacity and manufacture selected by it, and
that it is satisfied that the Equipment is suitable for its purposes. LESSEE
LEASES THE EQUIPMENT AS IS, AND, NOT BEING THE MANUFACTURER OF THE EQUIPMENT,
THE MANUFACTURER'S AGENT OR THE SELLER'S AGENT, LESSOR MAKES NO WARRANTY OR
REPRESENTATION, EXPRESS OR IMPLIED, AS TO THE MERCHANTABILITY, FITNESS FOR ANY
PARTICULAR PURPOSE, DESIGN OR CONDITION OF THE EQUIPMENT. LESSOR SHALL NOT BE
RESPONSIBLE FOR ANY LOSS OR DAMAGE RESULTING FROM THE INSTALLATION, OPERATION OR
OTHER USE, OR DEINSTALLATION OF THE EQUIPMENT, INCLUDING ANY DIRECT, INDIRECT,
INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSS. Lessee shall look solely to the
manufacturer or the supplier of the Equipment for correction of any problems
that may arise with respect thereto, and all transferable manufacturer and
supplier warranty rights are, to the extent such rights have been transferred to
Lessor, hereby assigned without representation or warranty by Lessor to Lessee
for the Lease Term, which warranties Lessee is authorized to enforce if and when
there exists no Event of Default. Any such enforcement shall be at Lessee's sole
cost and expense.

         2.2 INTELLECTUAL PROPERTY. Lessee acknowledges that neither this
Agreement nor any Lease conveys any explicit or implicit license for the use of
software or other intellectual property of Cisco Systems, Inc. or its affiliates
relating to the Equipment and that such license rights, to the extent they
exist, are contained in separate documentation entered into between Lessee and
Cisco Systems, Inc. or other persons. LESSOR MAKES NO WARRANTIES OR
REPRESENTATIONS WHATSOEVER WITH RESPECT TO THE INTELLECTUAL PROPERTY RIGHTS,
INCLUDING ANY PATENT, COPYRIGHT AND TRADEMARK RIGHTS, OF ANY THIRD PARTY WITH
RESPECT TO THE EQUIPMENT, WHETHER RELATING TO INFRINGEMENT OR OTHERWISE. Lessor
shall, when reasonably requested in writing by Lessee, provided there exists no
Event of Default and an indemnity satisfactory to Lessor is delivered by Lessee,
and at Lessee's cost and expense, enforce rights of indemnification, if any, for
patent, copyright or other intellectual property

                                       2.
<PAGE>

infringement obtained from the manufacturer under any agreement for purchase of
the Equipment. If notified promptly in writing of any action brought against
Lessee based on a claim that the Equipment infringes a United States patent,
copyright or other intellectual property right, Lessor shall promptly notify the
manufacturer thereof for purposes of exercising, for the benefit of Lessee,
Lessor's rights with respect to such claim under any such agreement.

                             III. LESSEE OBLIGATIONS

         3.1 NET LEASE; PAYMENTS UNCONDITIONAL. EACH LEASE IS A NET LEASE, AND
ALL COSTS, EXPENSES AND LIABILITIES RELATING TO THE EQUIPMENT, INCLUDING IN
RESPECT OF TAXES, INSURANCE AND MAINTENANCE, SHALL BE BORNE SOLELY BY LESSEE.
LESSEE'S OBLIGATION TO PAY ALL RENT AND OTHER SUMS THEREUNDER, AND THE RIGHTS OF
LESSOR IN AND TO SUCH PAYMENTS, SHALL BE ABSOLUTE AND UNCONDITIONAL, AND SHALL
NOT BE SUBJECT TO ANY ABATEMENT, REDUCTION, SETOFF, DEFENSE, COUNTERCLAIM,
INTERRUPTION, DEFERMENT OR RECOUPMENT, FOR ANY REASON WHATSOEVER.

         3.2 USE OF EQUIPMENT. Lessee shall use the Equipment solely in the
conduct of its business, in a manner and for the use contemplated by the
manufacturer thereof, and in compliance with all laws, rules and regulations of
every governmental authority having jurisdiction over the Equipment or Lessee
and with the provisions of all policies of insurance carried by Lessee pursuant
to Section 3.6.

         3.3 DELIVERY; INSTALLATION; RETURN; MAINTENANCE AND REPAIR; INSPECTION.
Lessee shall be solely responsible, at its own expense, for (a) the delivery of
the Equipment to Lessee, (b) the packing, rigging and delivery of the Equipment
back to Lessor, upon expiration or termination of the Lease Term, in good
repair, condition and working order, ordinary wear and tear excepted, at the
location(s) within the continental United States specified by Lessor, and (c)
the installation, de-installation, maintenance and repair of the Equipment.
During the Lease Term, Lessee shall ensure that the Equipment is covered by a
maintenance agreement, to the extent available, with the manufacturer of the
Equipment or other party reasonably acceptable to Lessor. Lessee shall, at its
expense, keep the Equipment in good repair, condition and working order,
ordinary wear and tear excepted, and at the expiration or termination of the
Lease Term with respect to any of the Equipment, have such Equipment inspected
and certified acceptable for maintenance service by the manufacturer. If any of
the Equipment, upon its return to Lessor, is not in good repair, condition and
working order, ordinary wear and tear excepted, and so inspected and certified,
Lessee shall be obligated to pay Lessor for the out-of-pocket expenses Lessor
incurs in bringing such Equipment up to such status, but not in excess of the
Casualty Value for such Equipment, promptly after its receipt of an invoice for
such expenses. Lessor shall be entitled to inspect the Equipment at reasonable
times.

         3.4 TAXES. Lessee shall pay, and hereby indemnifies Lessor on a net,
after-tax basis, against, and shall hold it harmless from, all license fees,
assessments, and sales, use, property, excise and other taxes and charges, other
than those measured by Lessor's net income, now and hereafter imposed by any
governmental body or agency upon or with respect to any of the Equipment, or the
possession, ownership, use or operation thereof, or any Lease, or the

                                       3.
<PAGE>

consummation of the transactions contemplated by any Lease. Notwithstanding the
foregoing, to the extent required of it by applicable law and in reliance upon
Lessee's disclosure of the location of such Equipment, Lessor shall file
personal property tax returns, and shall pay personal property taxes payable
with respect to the Equipment. Lessee shall pay to Lessor the amount of all such
personal property taxes within 15 days of its receipt of an invoice for such
taxes. For any Lease that is specified as an FMV Lease in the applicable
Schedule, Lessee acknowledges that it is the intent of Lessor, and a material
inducement to Lessor to enter into such Lease, to obtain all state and Federal
income tax benefits of ownership with respect to the Equipment under such Lease,
including entitlement to annual accelerated cost recovery deductions.

         3.5 LOSS OF EQUIPMENT. Lessee assumes the risk that, and shall promptly
notify Lessor in writing if, any item of Equipment becomes lost, stolen,
damaged, destroyed or otherwise unfit or unavailable for use from any cause
whatsoever (an "EVENT OF LOSS") after it has been delivered to a common carrier
for shipment to Lessee. Unless the item is damaged and is reparable within a
reasonable period of time in the judgment of Lessor (in which event Lessee shall
promptly cause such item to be repaired and restored to the condition and value
it had prior to such Event of Loss, at its own cost and expense), Lessee shall
pay to Lessor on the Rent payment date following Lessor's receipt of such notice
(or, if none, 30 days after such Event of Loss), an amount equal to the Rent
payment or payments due and payable with respect to such Equipment on or prior
to such date, plus a sum equal to the Casualty Value of such Equipment as of
such date. Upon making such payment, the Rent for such Equipment shall cease to
accrue, the term of the Lease as to such Equipment shall terminate and (except
in the case of loss, unrecovered theft or complete destruction) Lessor shall be
entitled to recover possession of such Equipment in accordance with the
provisions of Section 3.3 above. If Lessor has received the foregoing amount,
Lessee shall be entitled to the proceeds of any recovery in respect of such
Equipment from insurance or otherwise, provided that if the Equipment is subject
to an FMV Lease, Lessee shall be entitled to receive such proceeds only up to
the Casualty Value therefor, any excess amount to be paid to Lessor.

         3.6 INSURANCE. Lessee shall obtain and maintain for the Lease Term at
its own expense, property damage and liability insurance and insurance against
loss or damage to the Equipment as a result of fire, explosion, theft, vandalism
and such other risks of loss as are normally maintained on equipment of the type
leased hereunder by companies carrying on the business in which Lessee is
engaged, in such amounts, in such form and with such insurers as shall be
satisfactory to Lessor. Each insurance policy shall name Lessee as insured and
Lessor and its assignees as additional insureds and loss payees thereof as their
interest may appear, and shall provide that it may not be cancelled or altered
without at least 30 days' prior written notice thereof being given to Lessor (or
10 days', in the event of non-payment of premium).

         3.7 INDEMNITY. Except with respect to the gross negligence or willful
misconduct of Lessor, Lessee hereby indemnifies, protects, defends and holds
harmless Lessor from and against any and all claims, liabilities (including
negligence, tort and strict liability), demands, actions, suits, and
proceedings, losses, costs, expenses and damages, including reasonable
attorneys' fees and costs (collectively, "CLAIMS"), arising out of, connected
with, or resulting from any Lease or any of the Equipment, or any ancillary or
related software or other intangibles, whether arising before, during or after
the Lease Term (but not Claims relating to events occurring after Lessee

                                       4.
<PAGE>

has returned the Equipment to Lessor in accordance with Section 3.3), including
Claims relating to the manufacture, selection, purchase, delivery, possession,
condition, use, operation, return or other disposition of the Equipment. Each of
the parties shall give the other prompt written notice of any Claim of which it
becomes aware.

         3.8 PROHIBITIONS RELATED TO LEASE AND EQUIPMENT. Without the prior
written consent of Lessor, which consent as it pertains to clauses (b) and (d)
below shall not be unreasonably withheld, Lessee shall not: (a) assign,
transfer, or otherwise dispose of any Equipment, the Lease or any rights or
obligations thereunder; (b) sublease any of the Equipment or permit the
Equipment to be controlled by any other person; (c) create or incur, or permit
to exist, any security interest, lien or encumbrance with respect to any of the
Equipment; (d) cause or permit any of the Equipment to be moved from the
location specified in the applicable Schedule; or (e) cause or permit any of the
Equipment to be moved outside the United States.

         3.9 IDENTIFICATION. Lessee shall place and maintain permanent markings
provided by Lessor on the Equipment evidencing ownership, security and other
interests therein, as specified from time to time by Lessor.

         3.10 ALTERATIONS AND MODIFICATIONS. Lessee shall not make any
additions, attachments, alterations or improvements to the Equipment without the
prior written consent of Lessor, not to be unreasonably withheld. Any addition,
attachment, alteration or improvement to any item of Equipment shall belong to
and become the property of Lessor unless, at the request of Lessor, it is
removed prior to the return of such item of Equipment by Lessee. Lessee shall be
responsible for all costs relating to such removal and shall restore such item
of Equipment to the condition and value otherwise required hereunder.

         3.11 PERSONAL PROPERTY. Lessee acknowledges and represents that the
Equipment shall be and remain personal property, notwithstanding the manner by
which it may be attached or affixed to realty, and Lessee shall do all acts and
enter into all agreements necessary to ensure that the Equipment remains
personal property. If requested by Lessor with respect to any item of Equipment,
Lessee shall obtain and deliver to Lessor equipment access agreements,
satisfactory to Lessor, from all persons claiming any interest in the real
property on which such item of Equipment is installed or located.

         3.12 FINANCIAL STATEMENTS. Lessee shall promptly furnish to Lessor such
financial or other statements regarding the condition and operations of Lessee
and any guarantor of any Lease, and information regarding the Equipment, as
Lessor may from time to time reasonably request.

         3.13 LESSEE REPRESENTATIONS. Lessee hereby represents that, with
respect to this Agreement, and each Schedule, certificate evidencing acceptance
of equipment, assignment of purchase order, insurance letter, proposal letter,
UCC financing statement, or other document now or hereafter executed by Lessee
in connection with any Lease (collectively, "LEASE DOCUMENTS"): (a) the
execution, delivery and performance thereof by Lessee or its attorney-in-fact
have been duly authorized by all necessary corporate, partnership or company
action; (b) the person executing such documents is duly authorized to do so; and
(c) such documents constitute legal, valid and binding obligations of Lessee,
enforceable in accordance with their terms.

                                       5.
<PAGE>

                            IV. DEFAULT AND REMEDIES

         4.1 EVENTS OF DEFAULT. The occurrence of any of the following shall
constitute an "EVENT OF DEFAULT" hereunder and under each Lease: (a) Lessee
fails to pay any Rent or other amount due under any Lease within five days after
it becomes due and payable; (b) any representation or warranty of Lessee made in
any Lease Document proves to have been false or misleading in any material
respect as of the date when it was made; (c) Lessee fails to maintain insurance
as required herein or breaches any of clauses (a), (b) or (e) of Section 3.8;
(d) Lessee fails to perform any other covenant, condition or agreement made by
it under any Lease, and such failure continues for 20 days; (e) bankruptcy,
receivership, insolvency, reorganization, dissolution, liquidation or other
similar proceedings are instituted by or against Lessee, any guarantor of any
Lease or any partner of a partnership Lessee or guarantor, or all or any part of
such person's property, under the Federal Bankruptcy Code or other law of the
United States or of any other competent jurisdiction, and, if such proceeding is
brought against such person, it consents thereto or fails to cause the same to
be discharged within 45 days after it is filed; (f) Lessee materially defaults
under any agreement with respect to the purchase or installation of any of the
Equipment; or (g) Lessee or any guarantor of any Lease, or any of their
respective subsidiaries or other affiliates, defaults under any other instrument
or agreement with Lessor or Cisco Systems, Inc.

         4.2 REMEDIES. If an Event of Default exists, Lessor may exercise any
one or more of the following remedies, in addition to those arising under
applicable law: (a) proceed, by appropriate court action, to enforce performance
by Lessee of the applicable covenants of any or all of the Leases; (b) terminate
any or all Leases by notice to Lessee and take possession of any or all of the
Equipment and, for such purpose, enter upon any premises where the Equipment is
located with or without notice or process of law and free from all claims by
Lessee or any other person, or require Lessee to assemble the Equipment and
deliver it to Lessor in accordance with Section 3.3; (c) recover any and all
direct, incidental and consequential damages, including all accrued and unpaid
Rent and other amounts owing under any Lease, and (i) for any Lease that is an
FMV Lease, the Equipment for which has not been returned to Lessor in the
condition required hereunder, an amount equal to the Casualty Value thereof; or
(ii) for any Lease that is an FMV Lease, the Equipment for which has been so
returned to Lessor, such amounts as are provided for the lessee breach of a
personal property lease under the Uniform Commercial Code of the jurisdiction
specified in Section 5.11 (the "CODE"), using the Discount Rate to calculate
present values for such purpose; or (iii) for any Lease that is not an FMV
Lease, an amount equal to the present value, discounted at the Discount Rate, of
the sum of all Rent and other payments remaining to be paid under such Lease
through the Lease Term plus the applicable purchase option amount specified in
Paragraph 7 of the Schedule; and (d) sell or re-lease any or all of the
Equipment, through public or private sale or lease transactions, and apply the
proceeds thereof to Lessee's obligations under such Leases or otherwise seek
recovery in accordance with applicable provisions of the Code. Lessee shall
remain liable for any resulting deficiency and Lessor may retain any surplus it
may realize in connection with an FMV Lease. The "DISCOUNT RATE" shall be the
rate for U.S. Treasury obligations having a constant maturity of three months,
as specified in the Federal Reserve Statistical Release H.15 (or replacement
publication) issued most recently prior to the date of termination of the Lease.
Lessee shall pay all costs and expenses (including reasonable attorneys' fees)
incurred by Lessor in retaking possession of, and removing, storing,

                                       6.
<PAGE>

repairing, refurbishing and selling or leasing such Equipment and enforcing any
obligations of Lessee pursuant to any Lease.

                                V. MISCELLANEOUS

         5.1 PERFORMANCE OF LESSEE'S OBLIGATIONS. Upon Lessee's failure to pay
any amount or perform any obligation under any Lease when due, Lessor shall have
the right, but shall not be obligated, to pay such sum or perform such
obligation, whereupon such sum or cost of such performance shall immediately
become due and payable thereunder, with interest thereon at the Default Rate
from the date such payment or performance was made.

         5.2 RIGHT TO USE. So long as no Event of Default exists, neither Lessor
nor its assignee shall interfere with Lessee's right to use the Equipment under
any Lease.

         5.3 ASSIGNMENT BY LESSOR. Lessor may assign or transfer any or all of
Lessor's interest in this Agreement, any Lease, any Equipment or Rents, without
notice to Lessee. Any assignee of Lessor shall have all of the rights, but none
of the obligations (unless otherwise provided in the applicable assignment), of
a "Lessor" under this Agreement and the applicable Lease, and Lessee agrees that
it will not assert against any assignee any defense, counterclaim or offset that
Lessee may have against Lessor or any preceding assignee, and that upon notice
of such assignment or transfer, it will pay all Rent and other sums due under
this Agreement and the applicable Lease to such assignee or transferee. Lessee
acknowledges that any assignment or transfer by Lessor shall not materially
change Lessee's duties or obligations under this Agreement or any Lease, nor
materially increase the burdens or risks imposed on Lessee.

         5.4 FURTHER ASSURANCES. Upon the request of Lessor from time to time,
Lessee shall execute and deliver such further documents and do such further acts
as Lessor may reasonably request in order fully to effect the purposes of this
Agreement or any Lease. Lessee hereby appoints Lessor its attorney in fact,
coupled with an interest, authorized, without any obligation to do so, (a) to
sign on Lessee's behalf and file, record and register financing statements, and
amendments and continuations thereof, and any other documents relating to liens,
security interests or property rights of Lessor, Lessee or any third person with
respect to any Equipment and ancillary property, in accordance with any Uniform
Commercial Code or other code or statute, and (b) to enforce, in its own name or
in the name of Lessee, claims relating to any Equipment against insurers,
manufacturers or other persons, and to make, adjust, settle, compromise and
receive payments as to such claims.

         5.5 RIGHTS AND REMEDIES. Each right and remedy granted to Lessor under
any Lease shall be cumulative and in addition to any other right or remedy
existing in equity, at law, by virtue of statute or otherwise, and may be
exercised by Lessor from time to time concurrently or independently and as often
and in such order as Lessor may elect. Any failure or delay on the part of
Lessor in exercising any such right or remedy shall not operate as a waiver
thereof.

         5.6 NOTICES. Any notice, request, demand, consent, approval or other
communication provided for or permitted in relation to any Lease shall be in
writing and shall be conclusively deemed to have been received by a party hereto
on the day it is delivered to such party at its address, or received by the
party at such facsimile number, as is set forth in such Lease (or at

                                       7.

such other addresses or fax numbers such party shall specify to the other party
in writing), or if sent by registered or certified mail, return receipt
requested, on the fifth day after the day on which it is mailed, postage
prepaid, addressed to such party.

         5.7 SECTION HEADINGS; INTERPRETATION. Section headings are inserted for
convenience of reference only and shall not affect any construction or
interpretation of any Lease Document. In interpreting the provisions of any
Lease Document, (a) the term "including" is not limiting; (b) references to
"person" include individuals, corporations and other legal persons and entities;
(c) the singular of defined terms includes the plural and vice-versa; and (d)
section and paragraph references are to the document in which such reference
appears, unless the context otherwise requires.

         5.8 ENTIRE LEASE. This Agreement, together with the other Lease
Documents, constitute the entire agreement between Lessor and Lessee with
respect to the lease of the Equipment. No waiver or amendment of, or any consent
with respect to, any provision of any Lease Document shall bind either party
unless set forth in a writing, specifying such waiver, consent, or amendment,
signed by both parties. TO THE EXTENT PERMITTED BY APPLICABLE LAW AND NOT
OTHERWISE SPECIFICALLY GRANTED TO LESSEE IN ANY LEASE DOCUMENT, LESSEE HEREBY
WAIVES ANY AND ALL RIGHTS OR REMEDIES CONFERRED UPON A LESSEE UNDER THE CODE OR
ANY OTHER APPLICABLE LAW OR STATUTE, WITH RESPECT TO A DEFAULT BY LESSOR UNDER
THIS AGREEMENT OR ANY LEASE. Each FMV Lease is intended by the parties as a
"finance lease" under the Code.

         5.9 SEVERABILITY. Should any provision of any Lease Document be or
become invalid, illegal, or unenforceable under applicable law, the other
provisions of such Lease Document shall not be affected and shall remain in full
force and effect.

         5.10 ATTORNEYS' FEES; DEFAULT INTEREST; MAXIMUM RATES. Lessee shall
reimburse Lessor for all charges, costs, expenses and attorney's fees incurred
by Lessor (a) in defending or protecting its interests in the Equipment, (b) in
the enforcement of this Agreement or any Lease, and (c) in any lawsuit or other
legal proceeding to which this Agreement or any Lease gives rise. Any nonpayment
of Rent or other amount payable under any Lease shall result in Lessee's
obligation to promptly pay Lessor on such overdue payment, for the period of
time during which it is overdue (including during any grace period), interest at
a rate ("DEFAULT RATE") equal to fourteen percent (14%) per annum. To the extent
that any payment of interest (including any amount deemed imputed interest for
purposes of applicable law) under any Lease Document would otherwise exceed
provisions of any law limiting the highest rate of interest that may be lawfully
contracted for, charged or received by Lessor, such payment amount shall be
deemed reduced to such amount as is equal to or consistent with the highest rate
permitted by applicable law.

         5.11 GOVERNING LAW AND JURISDICTION. THIS AGREEMENT AND THE OTHER LEASE
DOCUMENTS SHALL BE GOVERNED IN ALL RESPECTS BY THE LAWS OF THE STATE OF
CALIFORNIA. LESSOR AND LESSEE WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY
LITIGATION ARISING FROM ANY LEASE DOCUMENT. LESSEE CONSENTS TO THE NON-EXCLUSIVE
JURISDICTION OF THE STATE

                                       8.

COURTS OF CALIFORNIA, AND THE FEDERAL COURTS SITTING IN THE STATE OF CALIFORNIA,
FOR THE RESOLUTION OF ANY DISPUTES UNDER ANY LEASE DOCUMENT.

         5.12 SURVIVAL. All obligations of Lessee to make payments to Lessor
under any Lease or to indemnify Lessor, including pursuant to Section 3.4 or 3.7
above, with respect to a Lease, and all rights of Lessor hereunder with respect
to a Lease, shall survive the termination of such Lease and the return of the
Equipment.

         5.13 SECURITY. To secure the payment and performance by Lessee of all
obligations under each Lease, Lessee hereby grants Lessor a security interest in
Lessee's right, title and interest, now existing and hereafter arising, in and
to, (a) all Equipment subject to such Lease, (b) all insurance, warranty, rental
and other claims and rights to payment and chattel paper arising out of such
Equipment, and (c) all books, records and proceeds relating to the foregoing.

         5.14 COUNTERPARTS; CHATTEL PAPER. Each Lease Document may be executed
in counterparts, and when so executed each counterpart shall be deemed to be an
original, and such counterparts together shall constitute one and the same
instrument. The original of each Schedule shall constitute chattel paper for
purposes of the Code. If there exist multiple originals of a Schedule, the one
marked "Lessor's Copy" or words of similar import, shall be the only chattel
paper.

         5.15 APPENDIX. Any lease Appendix executed by Lessor and Lessee making
reference to this Agreement is a part of and incorporated into this Agreement by
this reference.
