DATED AS OF NOVEMBER 8, 2000

                            TERREMARK WORLDWIDE, INC.

              INCORPORATED UNDER THE LAWS OF THE STATE OF DELAWARE

               WARRANT FOR THE PURCHASE OF SHARES OF COMMON STOCK

NO. W-_____

         FOR VALUE RECEIVED, Terremark Worldwide, Inc., a Delaware corporation
(the "Company"), hereby certifies that __________________, or its registered
assigns (the "Holder") is entitled, subject to the provisions of this Warrant,
to purchase from the Company, ________ fully paid and non-assessable shares of
Common Stock for an aggregate price of $ ________ or $____ per share (the
"Exercise Price").

         The term "Common Stock" means the Common Stock, par value $.001 per
share, of the Company. The number of shares of Common Stock to be received upon
the exercise of this Warrant and the Exercise Price may be adjusted from time to
time as hereinafter set forth. The shares of Common Stock deliverable upon such
exercise, and as adjusted from time to time, are hereinafter referred to as
"Warrant Stock." The term "Other Securities" means any other equity or debt
securities that may be issued by the Company in addition thereto or in
substitution for the Warrant Stock. The term "Company" means and includes the
corporation named above as well as (i) any immediate or more remote successor
corporation resulting from the merger or consolidation of such corporation (or
any immediate or more remote successor corporation of such corporation) with
another corporation, or (ii) any corporation to which such corporation (or any
immediate or more remote successor corporation of such corporation) has
transferred its property or assets as an entirety or substantially as an
entirety.

         The Holder agrees with the Company that this Warrant is issued, and all
the rights hereunder shall be held subject to, all of the conditions,
limitations and provisions set forth herein. The Company will act, or in the
event it designates a Warrant Agent, the Warrant Agent will act on behalf of the
Company, in connection with the issuance, registration, transfer, exchange and
redemption of the Warrants, the exercise of the Warrants, and the rights of the
holders thereof.

         1. EXERCISE OF WARRANT. This Warrant may be exercised in whole or in
part at any time, or from time to time during the period commencing on the date
hereof and expiring 5:00 p.m. Eastern Time on November 8, 2008 (the "Expiration
Date"), by presentation and surrender of this Warrant to the Company at its
principal office, or at the office of its Warrant Agent, if any, with the
Warrant Exercise Form attached hereto duly executed and accompanied by payment
(either in cash or by certified or official bank check or wire transfer, each
payable to the order of the Company) of the Exercise Price for the number of
shares specified in such form and instruments of transfer, if appropriate, duly
executed by the Holder or his or her duly authorized attorney. If this Warrant
should be exercised in part only, the Company shall, upon surrender of this
Warrant for cancellation, execute and deliver a new Warrant evidencing the
rights of the Holder thereof to purchase the balance of the shares purchasable
hereunder. Upon receipt by the Company of this Warrant, together with the
Exercise Price, at its office, or by the Warrant Agent of the Company at its
office, in proper form for exercise, the Holder shall be deemed to be the holder
of record of the shares of Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or that certificates representing such shares of Common Stock shall not
then be actually delivered to the Holder.

         2. FRACTIONAL SHARES. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant, but the
Company shall pay the Holder an amount equal to the fair market value of such
fractional share of Common Stock in lieu of each fraction of a share otherwise
called for upon any exercise of this Warrant. For purposes of this Warrant, the
fair market value of a share of Common Stock shall mean:

                  (i) if the shares of Common Stock are listed or admitted for
         trading on a national securities exchange, the last reported sales
         price regular way, or, in the case no such reported sale takes place on
         such day or days, the average of the reported closing bid and asked
         prices regular way, in either case on the principal national securities
         exchange on which the shares of the Common Stock are listed or admitted
         for trading, or (ii) if the shares of Common Stock are not listed or
         admitted for trading on a national securities exchange (A) the last
         transaction price for the Common Stock on The Nasdaq Stock Market
         ("Nasdaq") or, in the case no such reported transaction takes place on
         such day or days, the average of the reported closing bid and asked
         prices thereof quoted on Nasdaq, or (B) if the shares of Common Stock
         are not quoted on Nasdaq, the average of the closing bid and asked
         prices of the Common Stock as quoted on the Over-The-Counter Bulletin
         Board maintained by the National Association of Securities Dealers,
         Inc. (the "Bulletin Board"), or (C) if the shares of Common Stock are
         not quoted on Nasdaq or on the Bulletin Board, the average of the
         closing bid and asked prices of the Common Stock in the
         over-the-counter market, as reported by The National Quotation Bureau,
         Inc., or an equivalent generally accepted reporting service, or (iii)
         if on any such trading day or days the shares of Common Stock are not
         quoted by any such organization, the fair market value of the shares of
         Common Stock on such day or days, as determined in good faith by the
         Board of Directors of the Company.

         3.  RESERVATION OF SHARES; PAYMENT OF TAXES; ETC.

         (a) The Company covenants that it will at all times reserve and keep
available out of its authorized Common Stock, solely for the purpose of issue
upon exercise of Warrants, such number of shares of Common Stock as shall then
be issuable upon the exercise of all outstanding Warrants. The Company covenants
that all shares of Common Stock which shall be issuable upon exercise of the
Warrants and payment of the Exercise Price shall, at the time of delivery, be
duly and validly issued, fully paid, nonassessable and free from all taxes,
liens and charges with respect to the issue hereof (other than those which the
Company shall promptly pay or discharge).

         (b) The Company will use commercially reasonable efforts to obtain
appropriate approvals or registrations under state "blue sky" securities laws
with respect to the exercise of the Warrants; PROVIDED, HOWEVER, that the
Company shall not be obligated to file any general consent to service of process
or qualify as a foreign corporation in any jurisdiction. With respect to any
such securities laws, however, Warrants may not be exercised by, or shares of
Common Stock issued to, any Holder in any state in which such exercise would be
unlawful.

         (c) The Company shall pay all documentary, stamp or similar taxes and
other governmental charges that may be imposed with respect to the issuance of
Warrants, or the issuance, or delivery of any shares upon exercise of the
Warrants; PROVIDED, HOWEVER, that if the shares of Common Stock are to be
delivered in a name other than the name of the Holder representing any Warrant
being exercised, then no such delivery shall be made unless the person
requesting the same has paid to the Company or the Warrant Agent the amount of
transfer taxes or charges incident thereof, if any.

         4.  EXCHANGE AND REGISTRATION OF TRANSFER.

         (a) This Warrant may be exchanged for other Warrants representing an
equal aggregate number of Warrants of the same class or may be transferred in
whole or in part. Warrants to be exchanged shall be surrendered to the Company,
or the Warrant Agent, as the case may be, at its corporate office, and upon
satisfaction of the terms and provisions hereof, the Company shall execute, and
the Warrant Agent shall countersign, issue and deliver in exchange therefor the
Warrants which the Holder making the exchange shall be entitled to receive.

         (b) The Company, or the Warrant Agent, as the case may be, shall keep
at its office books in which it shall register Warrants and the transfer thereof
in accordance with its regular practice.

         (c) The Company may require payment by such Holder of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
therewith.

         (d) Prior to due presentment for registration of transfer thereof, the
Company and the Warrant Agent, if one shall be serving, may deem and treat the
Holder as the absolute owner thereof and of each Warrant represented thereby
(notwithstanding any notations of ownership or

                                       3
<PAGE>

writing thereon made by anyone other than a duly authorized officer of the
Company or the Warrant Agent) for all purposes and shall not be affected by any
notice to the contrary.

         5. LOSS OR MUTILATION. Upon receipt by the Company and the Warrant
Agent, if one shall be serving, of evidence satisfactory to them of the
ownership of and loss, theft, destruction or mutilation of any Warrant and (in
case of loss, theft or destruction) of indemnity satisfactory to them, and (in
the case of mutilation) upon surrender and cancellation thereof, the Company
shall execute and the Warrant Agent, if one shall be serving, shall (in the
absence of notice to the Company and/or Warrant Agent that the Warrant has been
acquired by a bona fide purchaser) countersign and deliver to the Holder in lieu
thereof a new Warrant of like tenor representing an equal aggregate number of
Warrants. Applicants for a substitute Warrant shall comply with such other
reasonable regulations and pay such other reasonable charges as the Company or
the Warrant Agent may prescribe.

         6. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES OF COMMON STOCK OR
WARRANTS. The type and number of securities of the Company issuable upon
exercise of this Warrant and the Exercise Price are subject to adjustment as set
forth below:

         (a) The Exercise Price and the number and type of securities and/or
other property issuable upon exercise of this Warrant shall be appropriately and
proportionately adjusted to reflect any stock dividend, stock split, combination
of shares, reclassification, recapitalization or other similar event affecting
the number or character of outstanding shares of the Common Stock.

         (b) In case of any consolidation or merger of the Company with or into
any other corporation, entity or person, or any other corporate reorganization,
in which the Company shall not be the continuing or surviving entity of such
consolidation, merger or reorganization (any such transaction being hereinafter
referred to as a "Reorganization"), then, in each case, the holder of this
Warrant, on exercise hereof at any time after the consummation or effective date
of such Reorganization shall receive, in lieu of the Common Stock issuable upon
exercise of the Warrants prior to the date of such Reorganization, the stock and
other securities and property (including cash) to which such holder would have
been entitled upon the date of such Reorganization if such holder had exercised
this Warrant immediately prior thereto.

         (c) In case of any adjustment in the Exercise Price or number and type
of securities issuable on the exercise of this Warrant, the Company will
promptly give written notice thereof to the holder of this Warrant in the form
of a certificate, certified and confirmed by an officer of the Company, setting
forth such adjustment and showing in reasonable detail the facts upon which such
adjustment is based.

         7.  REGISTRATION RIGHTS AND LISTING.

         (a) The Company shall use its commercially reasonable efforts to cause
to be effective a registration statement on or prior to December 31, 2001 under
the Securities Act, to permit the resale of the Warrant Stock by a holder
thereof. The Company shall use its commercially reasonable efforts to cause such
registration statement to remain effective until the

                                       4
<PAGE>

earlier to occur of (i) the expiration of the time period referred to in Rule
144(k) under the Securities Act with respect to all beneficial holders of the
Warrant Stock other than affiliates of the Company and (ii) such time as all the
restricted Warrant Stock covered by any registration statement have been sold or
are otherwise freely tradable without registration under the Securities Act.

         (b) In connection with the foregoing, the Company will:

                  (i) Prepare and file with the Securities and Exchange
Commission (the "Commission") a registration statement with respect to such
securities and use its commercially reasonable efforts to cause such
registration statement to become and remain effective.

                  (ii) Prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective and
to comply with the provisions of the Securities Act with respect to the sale or
other disposition of all securities covered by such registration statement
whenever the holder of such securities shall desire to sell the same.

                  (iii) Furnish to holder such number of copies of a summary
prospectus or other prospectus, including a preliminary prospectus, in
conformity with the requirements of the Securities Act, and such other documents
as holder may reasonably request in order to facilitate the sale of the Warrant
Stock owned by holder.

                  (iv) Use its commercially reasonable efforts to register or
qualify the securities covered by such registration statement under such other
securities or blue sky laws of such jurisdictions within the United States and
Puerto Rico as the holder shall reasonably request, and do such reasonable acts
and things as may be required in such jurisdiction; PROVIDED, HOWEVER, that the
Company shall not be obligated to file any general consent to service of process
or qualify as a foreign corporation in any jurisdiction.

                  (v) Furnish at the request of holder, on the date that such
Warrant Stock is delivered to the underwriters for sale pursuant to an
underwritten registration or, if such Warrant Stock is not being sold through
underwriters, on the date that the registration statement with respect to such
Warrant Stock becomes effective, an opinion, dated such date, of the counsel
representing the Company for the purposes of such registration, addressed to the
underwriters, if any, and if the Warrant Stock is not being sold through
underwriters, then to the holder, stating that such registration statement has
become effective under the Securities Act and that (a) to the knowledge of such
counsel, no stop order suspending the effectiveness thereof has been issued and
no proceedings for that purpose have been instituted or are pending or
contemplated under the Securities Act, (b) the registration statement, the
related prospectus and each amendment or supplement thereto, comply as to form
in all material respects with the requirements of the Securities Act and the
applicable rules and regulations of the Commission thereunder (except that such
counsel need express no opinion as to financial statements contained therein),
(c) such counsel has no reason to believe that either the registration statement
or the prospectus, or any amendment or supplement thereof, contains any untrue
statement of a material fact required to be stated therein or necessary to make
the statements therein not misleading, (d) the descriptions in

                                       5
<PAGE>

the registration statement or the prospectus, or any amendment or supplement
thereto, of all legal matters and contracts and other legal documents or
instruments are accurate and fairly present the information required to be
shown, and (e) such counsel does not know of any legal or governmental
proceedings, pending or contemplated, required to be described in the
registration statement or prospectus, or any amendment or supplement thereto,
which are not described as required, nor of any contracts or documents or
instruments or a character required to be described in the registration
statement or prospectus, or any amendment or supplement thereto, or to be filed
as exhibits to the registration statement which are not described and filed or
incorporated by reference as required. Such opinion of counsel shall
additionally cover such other legal matters with respect to the registration in
respect of which such opinion is being given as holder may reasonably request.

         (c) All of the expenses incurred in complying with the foregoing,
including, without limitation, all registration and filing fees (including all
expenses incident to filing with the NASD), printing expenses, fees and
disbursements of counsel for the Company, expenses of any special audits
incident to or required by any such registration and expenses of complying with
the securities or blue sky laws or any jurisdictions shall be paid by the
Company.

         (d) The Company shall also use its commercially reasonable efforts to
cause such Warrant Stock to be listed on the American Stock Exchange or such
other principal national securities exchange on which the shares of Common Stock
are then listed or if the shares are not so listed, on The Nasdaq Stock Market,
if the shares are then listed on such market.

         8. WARRANT HOLDERS NOT DEEMED STOCKHOLDERS. No holder of Warrants,
shall, as such, be entitled to vote or to receive dividends or be deemed the
holder of Common Stock that may at any time be issuable upon exercise of such
Warrants for any purpose whatsoever, nor shall anything contained herein be
construed to confer upon the holder of Warrants, as such, any of the rights of a
stockholder of the Company or any right to vote for the election of directors or
upon any matter submitted to stockholders at any meeting thereof, or to give or
withhold consent to any corporate action (whether upon any recapitalization,
issue or reclassification of stock, change of par value or change of stock to no
par value, consolidation, merger or conveyance or otherwise), or to receive
notice of meetings, or to receive dividends or subscription rights, until such
holder shall have exercised such Warrants and been issued shares of Common Stock
in accordance with the provisions hereof.

         9. RIGHTS OF ACTION. All rights of action with respect to this Warrant
are vested in the respective Holder of the Warrants, and the Holder, without
consent of the Warrant Agent or the holder of any other Warrant, may, on his or
her own behalf and for his or her own benefit, enforce against the Company his
right to exercise his or her Warrants for the purchase of shares of Common Stock
in the manner provided in this Warrant.

         10. CONCERNING THE WARRANT AGENT. The Company reserves the right to
designate a Warrant Agent. If so designated, the Warrant Agent will act
hereunder as agent and in a ministerial capacity for the Company, and its duties
shall be determined solely by the provisions hereof. The Warrant Agent shall
not, by issuing and delivering Warrants or by any other act

                                       6
<PAGE>

hereunder be deemed to make any representations as to the validity, value or
authorization of the Warrants or the Warrants represented thereby or of any
securities or other property delivered upon exercise of any Warrant or whether
any stock issued upon exercise of any Warrant is fully paid and nonassessable.

         The Warrant Agent shall account promptly to the Company with respect to
Warrants exercised and concurrently pay the Company all moneys received by the
Warrant Agent upon the exercise of such Warrants. The Warrant Agent shall, upon
request of the Company from time to time, deliver to the Company such complete
reports of registered ownership of the Warrants and such complete records of
transactions with respect to the Warrants and the shares of Common Stock as the
Company may request. The Warrant Agent shall also make available to the Company
and the Holder for inspection by their agents or employees, from time to time as
either of them may request, such original books of accounts and records
(including original Warrants surrendered to the Warrant Agent upon exercise of
Warrants) as may be maintained by the Warrant Agent in connection with the
issuance and exercise of Warrants hereunder, such inspections to occur at the
Warrant Agent's office during normal business hours.

         The Warrant Agent shall not at any time be under any duty or
responsibility to any holder of Warrants to make or cause to be made any
adjustment of the Exercise Price provided in this Warrant, or to determine
whether any fact exists which may require any such adjustments, or with respect
to the nature or extent of any such adjustment, when made, or with respect to
the method employed in making the same. It shall not (i) be liable for any
recital or statement of facts contained herein or for any action taken, suffered
or omitted by it in reliance on any Warrant or other document or instrument
believed by it in good faith to be genuine and to have been signed or presented
by the proper party or parties, (ii) be responsible for any failure on the part
of the Company to comply with any of its covenants and obligations contained in
this Warrant, or (iii) be liable for any act or omission in connection with this
Warrant except for its own negligence or willful misconduct.

         The Warrant Agent may at any time consult with counsel satisfactory to
it (who may be counsel for the Company) and shall incur no liability or
responsibility for any action taken, suffered or omitted by it in good faith in
accordance with the opinion or advice of such counsel.

         Any notice, statement, instruction, request, direction, order or demand
of the Company shall be sufficiently evidenced by an instrument signed by the
Chairman of the Board, President, any Vice President, Secretary, or Assistant
Secretary of the Company, (unless other evidence in respect thereof is herein
specifically prescribed). The Warrant Agent shall not be liable for any action
taken, suffered or omitted by it in accordance with such notice, statement
instruction, request, direction, order or demand believed by it to be genuine.

         The Warrant Agent may resign its duties and be discharged from all
further duties and liabilities hereunder (except liabilities arising as a result
of the Warrant Agent's own negligence or willful misconduct), after giving 30
days prior written notice to the Company. At least 15 days prior to the date
such resignation is to become effective, the Warrant Agent shall cause a copy of
such notice of resignation to be mailed to the Holder at the Company's expense.
Upon

                                       7
<PAGE>

such resignation, or any inability of the Warrant Agent to act as such
hereunder, the Company may choose to perform the duties of the Warrant Agent
itself or can appoint a new warrant agent. After acceptance in writing of such
appointment by the new warrant agent is received by the Company, such new
warrant agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named herein as the Warrant Agent,
without any further assurance, conveyance, act or deed; but if for any reason it
shall be necessary or expedient to execute and deliver any further assurance,
conveyance, act or deed, the same shall be done at the expense of the Company
and shall be legally and validly executed and delivered by the resigning Warrant
Agent. Not later than the effective date of any such appointment, the Company
shall file notice thereof with the resigning Warrant Agent and shall forthwith
cause a copy of such notice to be mailed to the Holder.

         Any corporation into which the Warrant Agent or any new warrant agent
may be converted or merged or any corporation resulting from any consolidation
to which the Warrant Agent or any new warrant agent shall be a party or any
corporation succeeding to the trust business of the Warrant Agent shall be a
successor warrant agent under this Warrant without any further act, provided
that such corporation is eligible for appointment as successor to the Warrant
Agent under the provisions of the preceding paragraph. Any such successor
warrant agent shall promptly cause notice of its succession as warrant agent to
be mailed to the Company and to the Holder.

         The Warrant Agent, its subsidiaries and affiliates, and any of its or
their officers or directors, may buy and hold or sell Warrants or other
securities of the Company and otherwise deal with the Company in the same manner
and to the same extent and with like effects as though it were not Warrant
Agent. Nothing herein shall preclude the Warrant Agent from acting in any other
capacity for the Company or for any other legal entity.

         11. MODIFICATION OF AGREEMENT. The Company may from time to time
supplement or amend this Warrant in order to cure any ambiguity or to correct
any provision herein which may be erroneous, defective or inconsistent;
provided, however, that no change in the number or nature of the securities
purchasable upon the exercise of any Warrant, or the Exercise Price therefor, or
the acceleration of the Warrant Expiration Date, shall be made without the
consent in writing of the Holder, other than such changes as are specifically
prescribed by this Warrant as originally executed.

         12. NOTICES. All notices, requests, consents and other communications
hereunder shall be in writing and shall be deemed to have been made when
delivered or mailed first class registered or certified mail, postage prepaid as
follows: if to the Holder, at the address of such holder as shown on the
registry books maintained by the Company or the Warrant Agent, if one shall be
serving; if to the Company, at 2601 S. Bayshore Drive, Miami, Florida, 33133,
Attention: Brian Goodkind, Executive Vice President and Chief Operating Officer;
and if to the Warrant Agent, if one shall be serving, at its corporate office.

         13. GOVERNING LAW. This Warrant shall be governed by and construed in
accordance with the laws of the State of Florida, without reference to
principles of conflict of laws.

         14. BINDING EFFECT. This Warrant shall be binding upon and inure to the
benefit of the Company, the Holder and the Warrant Agent (and their respective
successors and assigns) and the holders from time to time of Warrants. Nothing
in this Warrant is intended or shall be construed to confer upon any other
person any right, remedy or claim, in equity or at law, or to impose upon any
other person any duty, liability or obligation.

         15. TERMINATION. This Warrant shall terminate on the earlier to occur
of (i) the close of business on the Expiration Date; or (ii) the date upon which
the Warrant has been exercised in full.

         16. TRANSFER TO COMPLY WITH THE SECURITIES ACT. Notwithstanding any
other provision contained herein, this Warrant and any Warrant Stock or Other
Securities may not be sold, transferred, pledged, hypothecated or otherwise
disposed of except as follows: (a) to a person who, in the opinion of counsel to
the Company, is a person to whom this Warrant or the Warrant Stock or Other
Securities may legally be transferred without registration and without the
delivery of a current prospectus under the Securities Act with respect thereto
and then only against receipt of an agreement of such person to comply with the
provisions of this Section 6 with respect to any resale or other disposition of
such securities; or (b) to any person upon delivery of a prospectus then meeting
the requirements of the Securities Act relating to such securities and the
offering thereof for such sale or disposition, and thereafter to all successive
assignees.

         17. LEGEND. Unless the shares of Warrant Stock or Other Securities have
been registered under the Securities Act, upon exercise of any of the Warrants
and the issuance of any of the shares of Warrant Stock or Other Securities, all
certificates representing such securities shall bear on the face thereof
substantially the following legend:

purposes only on September 13, 2000 (the "Reference Date"), Rainbow Property
Management, LLC, a California limited liability company, whose address is 18070
China Grade, Boulder Creek. California, 95006 ("Landlord") hereby leases to

certain real property located in Santa Clara County, California, at 3030 Corvin

described in Exhibit "A", which is attached hereto and incorporated herein by
reference (the "Land"), together with the appurtenances, buildings and
improvements erected or to be erected upon the Land in accordance with the terms
of this Lease, including a ore story industrial building containing
approximately forty thousand four hundred ninety-one (40,491) gross interior
square feet (the "Building"). (The Land and the Building are sometimes
collectively referred to herein as the "Leased Premises.") The Leased Premises
shall also include all right, title and interest of Landlord, if any, in and to
any land lying in the bed of any street, road or avenue, open or proposed, in
front of or adjoining the Land and in and to the easements, franchises, rights,
appendages and appurtenances belonging or appertaining to such real property.
Tenant shall lease the Leased Premises from Landlord on the terms and conditions
set forth herein including the Rules and Regulations, as they may be amended by
Landlord from time to time by Landlord, and subject to any superior liens or
encumbrances, and to all covenants, conditions, and restrictions of record with
respect thereto, and subject to all of the covenants, terms, and conditions of
this Lease. A current copy of said Rules and Regulations is attached hereto as
Exhibit "B" and incorporated herein by reference (the "Rules and Regulations").
Landlord shall not be liable in any way for failure of any party to comply with
and observe these titles and regulations. Landlord reserves the tight, at any
time, to renumber and/or redesignate the street address, suite number or unit
number of all or any portion of the Leased Premises if required by law or by the
decree of the U.S. postal service or other governmental or quasi-governmental
organization.

                                    ARTICLE 1
                                  TERM OF LEASE

         1.1 FIXED TERM. The term of this Lease shall be for a period of
approximately two hundred forty (240) months commencing upon October 1, 2000
(the "Commencement Date") and expiring on September 30, 2020 (the "Expiration
Date"), unless sooner terminated or extended as herein provided. Notwithstanding
the foregoing, if there shall be any Contingent Free Rent Period (as defined in
Section 2.2.1 below), the term of this Lease shall be extended (and the
Expiration Date postponed) an equal number of days as shall have comprised such
Contingent Free Rent Period, whereupon all references in this Lease to the
Expiration Date shall mean and refer to the final date of the extended term.

<PAGE>

Notwithstanding any other provision in this Lease, if Landlord does not deliver
possession of the Premises to Tenant by January 5, 2001 (the "Trigger Date"),
then within five (5) days of the Trigger Date, Tenant may give Landlord written
notice of Tenant's intent to terminate this Lease.

         1.2 EARLY OCCUPANCY. If Landlord shall deliver possession of the Leased
Premises to Tenant at any time prior to the Commencement Date, Tenant shall
accept delivery thereof and shall hold possession of the Leased Premises until
the Commencement Date subject to all of the terms and conditions of this Lease,
except that Tenant's obligation to pay Minimum Monthly Rent shall not commence
until the Commencement Date.

         1.3 HOLDOVER RENT. If Tenant should hold over and continue in
possession of the Leased Premises after termination of the term of this Lease or
any renewal or extension of the term of this Lease, Tenant's continued occupancy
of the Leased Premises shall be deemed merely a tenancy from month to month at a
Minimum Monthly Rent (as defined in Section 2.1 of this Lease below) equal to
one hundred fifty percent (150%) of the final rental amount due under this Lease
for the first two (2) calendar months that Tenant fails to vacate the Leased
Premises and two hundred percent (200%) of the final rental amount due under
this Lease for every calendar month thereafter that Tenant fails to vacate the
Leased Premises (the "Holdover Rent"), subject to all the terms and conditions
of this Lease, including provisions for payment of Additional Rent. If Tenant
shall holdover and fail to surrender the Leased Premises upon the termination of
this Lease without Landlord's consent, in addition to any other liabilities to
Landlord arising therefrom, Tenant shall and does hereby agree to indemnify,
defend, and hold Landlord harmless from loss or liability resulting from such
failure including, but not limited to, claims made by any succeeding tenant
founded on such failure.

         1.4 OPTION TO EXTEND TERM OF LEASE. Provided that the original Tenant
executing this Lease (and not any assignee, sublessee or other transferee of
such original Tenant or of such original Tenant's interest in the Lease) has
occupied not less than fifty percent (50%) of the floor area of the Building at
all times during the term of this Lease, and, provided further that original
Tenant is not in default of the terms and obligations in this Lease and that
this Lease has not been terminated, Tenant shall have two (2) consecutive
options to extend the term of this Lease for additional periods of sixty (60)
months each by giving Landlord written notice of Tenant's exercise of such
options (the "Extension Option Notice(s)") at a time no earlier than twelve (12)
months prior to the initial Expiration Date of the Lease and no later than nine
(9) months prior to the initial Expiration Date hereof or no earlier than twelve
(12) months prior to the expiration date of the First Option Period (as defined
below) and no later than nine (9) months prior to the expiration date of the
First Option Period. It shall be an absolute condition precedent to the exercise
of the second option that the first option be timely and properly exercised.
Upon exercise of the first option, the term of this Lease shall be extended for
an additional period of sixty (60) months from the initial Expiration Date (the
"First Option Period"), and upon the exercise of the second option the term of
this Lease shall be extended for an additional period of sixty (60) months from
the expiration of the First Option Period (tie "Second Option Period") upon the
same terms and conditions as set forth in this Lease, except for the Minimum
Monthly Rent, which shall be determined, upon the exercise of each option,

                                       2
<PAGE>

pursuant to terms of Section 2.7 below. Except as otherwise provided for in
Section 10.8 of this Lease, the option rights set forth in this section are
personal to the original Tenant executing the Lease and may be exercised only by
such original Tenant (and not by any assignee, sublessee or other transferee of
such original Tenant or of such original Tenant's interest in the Lease).

                                    ARTICLE 2
                                 RENT AND TAXES

         2.1 RENT. Commencing on the Commencement Date (the "Initial Rental
Date"), each month during the term of this Lease, Tenant shall pay to Landlord
minimum monthly rent (the "Minimum Monthly Rent") and additional rent (the
"Additional Rent") for the use and occupancy of the Leased Premises, determined
and adjusted in accordance with the provisions of this Lease, payable monthly in
lawful money of the United Stales, without any abatement, deduction or offset
whatsoever, and without any prior demand therefor. Rent shall be paid to
Landlord at the address specified in introductory paragraph of this Lease, or at
such other place or places as Landlord may from time to time designate by
written notice to Tenant. Payment of Minimum Monthly Rent for the first month of
the term of this Lease shall be due and payable upon execution of this Lease,
thereafter rent shall be due and payable in advance on the first day of each and
every calendar month during the term of this Lease. if Tenant's obligation to
pay rent should commence upon a day other than the first day of a calendar month
or terminate on other than the last day of a calendar month, all rentals shall
be prorated on the basis of a thirty (30) day month. Tenant agrees that Landlord
will incur additional expenses, including bookkeeping charges and processing
fees in the event that any payments required under this Lease are not timely
made. Tenant agrees that the exact nature and amount of these expenses are
difficult or impossible to ascertain at this time. Therefore, Tenant agrees
that, as reasonable damages to Landlord, and not as a penalty, any payment
required under this Lease, which is not made within five (5) days following the
due date for such payment, shall be subject to a Late charge in the amount of
six percent (6%) per annum of the amount of such delinquent payment, which late
charge shall be assessed as "Additional Rent". All past due rent, including, any
unpaid Additional Rent, shall, unless otherwise prohibited by law, accrue
interest at an interest rate equal to the lesser of the twelve percent (12%) per
annum or the maximum rate permitted by law. Unless restricted by law, payments
shall be applied first to accrued late charges, then to interest, then to
past-due rent (including, but not limited to all assessed Additional Rent, fees
and costs), and lastly to prospective rent.

         2.2 MINIMUM MONTHLY RENT. During the initial term of this Lease,
commencing on the Initial Rental Date, Tenant shall pay Minimum Monthly Rent to
Landlord as set forth in the Minimum Monthly Rent Schedule below:

(12) months of the First Option Period or the Second Option Period, as

(10%) greater than the lower of the two appraisals, then the average of the two
appraisals shall be conclusively established as the Fair Market Rental Value,
and the Initial Option Year Minimum Monthly Rent shall be established
accordingly. If the two appraisers are unable to agree on the Initial Option
Year Minimum Monthly Rent within said thirty (30) day period, the two appraisers
shall appoint a third appraiser who shall be a real estate appraiser with at
least ten (10) years full time commercial real estate appraisal experience in

agree on a third appraiser, then either party shall have the power to apply to

said Court appoint a third appraiser who meets the qualifications stated in this
section. Each of the parties shall bear one-half (1/4) of the cost of appointing

days after the selection of the third appraiser, such third appraiser shall
appraise the fair market rental value of the Leased Premises for the initial
twelve (12) months of the First Option Period or the Second Option Period, as
applicable, and the three appraisals shall be added together and their total
divided by three (3), the resulting quotient shall be the Initial Option Year
Minimum Monthly Rent, provided, however, that, except as set forth in the next
sentence, the Initial Option Year Minimum Monthly Rent shall not be: (i) lesser
than the lower of the two original appraisals; or (ii) greater than the higher
of the two original appraisals. Notwithstanding the foregoing, in no event shall
the Initial Option Year Minimum Monthly Rent be less than one hundred three
percent (103%) of the Minimum Monthly Rent payable by Tenant under the Lease for
the period immediately prior to the initial twelve (12) months of the First
Option Period or the Second Option Period: as applicable. In determining the
fair market rental value, each appraiser shall consider the highest and best use
for the Leased Premises, subject to the restrictions on use as set forth in
Section 3.1 of the Lease.

rent payable by Tenant until such determination shall be the applicable Holdover
Rent determined in accordance with Section 1.3 of this Lease above.

                  2.7.5 ADJUSTMENTS TO MINIMUM MONTHLY RENT DURING OPTION
PERIOD. The Minimum Monthly Rent payable during the First Option Period or the
Second Option Period, as applicable, shall be adjusted annually pursuant to this
section on each anniversary of the 1st day of the First Option Period or the
Second Option Period, as applicable (the "Adjustment Date(s)"). As of each
Adjustment Date, the Minimum Monthly Rent shall be increased to a sum equal to
one hundred three percent (103%) of the Minimum Monthly Rent or the Minimum
Monthly Rent, as adjusted, as the case may be, payable for the period
immediately prior to the applicable Adjustment Date. Landlord shall provide
Tenant with written notice of each such adjustment in the Minimum Monthly Rent
following Landlord's determination thereof; provided, however, that any failure
or delay on the part of Landlord in delivering such notice shall not relieve
Tenant from the obligation to pay Minimum Monthly Rent, during all periods
commencing on the relevant Adjustment Date. In the event that Landlord shall not
have delivered an adjustment notice on or before a given Adjustment Date, Tenant
shall continue to pay the Minimum Monthly Rent due for the period prior to the
relevant Adjustment Date, until Landlord shall deliver to Tenant the notice of
adjustment. Within ten (10) days following receipt of the relevant adjustment
notice, Tenant shall pay to Landlord any accrued unpaid rent for the period

Toxic Materials, it being understood that Tenant shall be solely' responsible
for all liability in connection therewith.

Toxic Materials, and that there have been no spills or contaminations by Tenant
at the Leased Premises that have not been fully corrected and cleaned up.

responsibility of Tenant, Landlord may require within fifteen (15) days after

of costs for cleaning up the contamination. The posting of the bond does not
relieve Tenant from fulfilling its responsibility to clean up the contamination.

Lease shall be proportionally reduced by an amount which shall be determined by
multiplying the then applicable Minimum Monthly Rent otherwise payable under
this Lease for the use and occupancy of the Premises by a ratio, the numerator

accordance with this section and the denominator of which is the number of
rentable square feet comprising the Premises prior to such recapture. Except for

constitute a material breach of this Lease and a default by Tenant: (i) Tenant
fails to pay Minimum Monthly Rent, `Additional Rent or any other sums as and
when due hereunder, where such failure continues for three (3) days after

Section 1161, et. seq. of the California Code of Civil Procedure or any
successor statute thereto or similar statute hereinafter enacted; (ii)
abandonment of the Leased Premises; (iii) assignment, encumbrance or subletting

the Leased Premises by Tenant; (vi) failure to purchase and maintain policies of

timely any other provision of this Lease, which performance shall be deemed
timely, where no time period has been specified elsewhere in this Lease, if

reasonably be cured within thirty (30) days, Tenant shall be excused from its
default of this Lease if Tenant commences to cure the default immediately upon
receipt of written notice from Landlord to do so and continuously, diligently,
and in good faith accomplishes such cure within a reasonable time thereafter.

         11.2 LANDLORD'S REMEDIES. Landlord shall have the remedies set forth in

exclusive; they are cumulative in addition to any remedies now or later allowed

parties.

         11.3 TENANT'S RIGHT TO POSSESSION NOT TERMINATED. Landlord has the
remedy described in California Civil Code Section 1951.4 (lessor may continue
lease in effect after lessee's breach and abandonment and recover rent as it
becomes due, if lessee has right to sublet or assign, subject only to reasonable
limitations). In connection with the foregoing. Landlord may elect to continue
this Lease in full force and effect, in which case Landlord shall have the right
to collect rent and other sums when due. During the period Tenant is in default,
Landlord may enter the Leased Premises and relet them, or any part of them, to
third parties for Tenant's account and alter or install locks and other security
devices at the Leased Premises, Tenant shall be liable immediately to Landlord

                                       29

term of this Lease and rent received by Landlord shall he applied to (1) first,
any indebtedness from Tenant to Landlord other than rent due from Tenant; (ii)
second, all reasonable costs incurred by Landlord in reletting; (iii) third,
rent due and unpaid under this Lease. After deducting the payments referred to
in this section, any sum remaining from the rent Landlord receives from
reletting shall be held by Landlord and applied in payment of future rent and
other amounts as rent and such amounts become due tinder this Lease. In no event
shall Tenant be entitled to any excess rent received by Landlord.

         11.4 TERMINATION OF TENANT'S RIGHT TO POSSESSION. Landlord can
terminate Tenant's right to possession of the Leased Premises or this Lease or
both at any time after a default by Tenant by giving notice to Tenant of
Landlord's election to do so and such termination shall be effective on the date
set forth in such notice. Acts of maintenance, efforts to relet the Leased
Premises, or the appointment of a receiver on Landlord's initiative to protect
Landlord's interest under this Lease shall not constitute a termination of
Tenant's right to possession. No act by Landlord other than giving notice to
Tenant shall terminate this Lease. On termination of this Lease, Landlord has
the right to recover from Tenant: (i) the worth, at the time of the award, of
the unpaid rent that had been earned at the time of termination of this Lease;
(ii) the worth, at the time of the award, of the amount by which the unpaid rent
that would have been earned after the date of termination of this Lease until
the time of award exceeds the amount of the loss of rent that Tenant proves
could have been reasonably avoided; (iii) the worth, at the time of the award,
of the amount by which the unpaid rent for the balance of the term after the
time of award exceeds the amount of the loss of rent that Tenant proves could
have been reasonably avoided; (iv) any other amount, and court costs, reasonably
necessary to compensate Landlord for all detriment proximately caused by
Tenant's default, or which in the ordinary course of things would be likely to
result therefrom, including, without limitation, the unamortized portion of
brokers' fees or commissions and reasonable attorneys' fees incurred by Landlord
in connection with the negotiation and execution of the Lease with Tenant; and
(vi "the worth, at the time of the award," as used in (i) and (ii) above, is to
be computed by allowing interest at the Default Interest Rate. "The worth, at
the time of the award," as referred to in (iii) , is to be computed by
discounting the amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of the award, plus one percent (1%).

         11.5 LANDLORD'S RIGHT TO CURE TENANT'S DEFAULT. If Tenant fails to
immediately commence and diligently and continuously prosecute to completion
performance of any of its obligations hereunder after notice by Landlord or any
governmental authority that it do so, and after expiration of the applicable
cure period, then Landlord, in addition to all other remedies available
hereunder or by law and equity, and without waiving any alternative remedies,
including the right to declare Tenant in breach and default of this Lease, may
perform the same, and in that event, Tenant shall reimburse Landlord, upon
demand, as Additional Rent, for all reasonable costs Landlord incurs in taking

by law in the case of nonpayment of Minimum Monthly Rent.

         11.8 LANDLORD DEFAULT. For purposes of this Lease, Landlord shall not
be deemed in default hereunder unless and until Tenant shall first deliver to
Landlord thirty (30) days' prior written notice, and Landlord shall fail to cure
said default within said thirty (30) day period, or in the event Landlord shall
reasonably requite in excess of thirty (30) days to cure said default, shall

                  3030 Corvin Drive
                  Santa Clara, California

<PAGE>

Dear Mr. Johnson:

Thank you for requesting our agreement for investigative services at the 3030
Corvin Drive facility. This document will serve as our agreement to work
together.

THE PROJECT

It is our understanding that Your client plans to lease the 3030 Corvin Drive
facility and, that under conditions of the lease, they will be responsible only
for contaminants they generate at the site. This investigation is designed o
evaluate existing subsurface conditions at the facility so that your client has
a "baseline" prior to occupying the facility. The site is bordered by Kifer Road
to the south, Copper Road. to the west, Central Expressway to the north, and
Corvin Road to the east.

LOCAL EXPERIENCE

Since 1969, Lowney Associates has provided geotechnical and environmental
services for more than 5,000 projects. We have prepared this agreement based on
our previous work in the area, our site visit and discussions with you.

PROJECT TEAM

Our team consists of Stason I Foster, Principal in Charge, and Douglas T. Young,
Project Manager. We are prepared to begin the following scope of work.

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

SCOPE OF SERVICES

We propose the following scope of work to evaluate soil and ground water quality
near the facility by 1) reviewing available environmental records from sites
near the facility, 2) collecting a water sample from an existing on-site
monitoring well (MW-12), and 3) analyzing soil and ground water samples from a
boring drilled in the vicinity of the proposed aboveground fuel storage area.

DOCUMENT REVIEW

We will review case histories that are on record at the Santa Clara Valley Water
District (SCVWDI) for facilities that are adjacent to and either up- or
cross-gradient to the Site. Review of these facility records may assist in
refining the analytical resting program for the site.

FIELD INVESTIGATION

We plan to drill one soil boring in the proposed fuel storage area to obtain
baseline chemical data from soil and ground water samples.

Pre-Field Activities: Prior to beginning work, we will contact Underground
Service Alert (USA) to attempt to locate public underground utilities in the
area of our exploratory boring. Please note that USA will not mark private
utility locations. We will need you to mark any private utilities at the site or
provide us with utility plans prior to on-site drilling. We recommend using a
private utility locator to help reduce the risk of damaging underground
utilities during drilling, especially on sites where little information is
available regarding existing underground utilities. We are nor. responsible for
damage to underground structures.

Subsurface Explorations Our field engineer or scientist will direct a subsurface
exploratory program, supervise, log, and sample one exploratory boring to a
depth of approximately 25 feet. Ground water is anticipated to be at a depth of
between 20 and 25 feet.

The subsurface investigation will be performed using a limited access rig
equipped with Direct Push Technology equipment. The boring will be advanced by
hydraulically driving a 2-inch diameter by 4-foot-long open sampler with an
interior clear acetate sample liner. After being driven to a depth of 4 feet,
the sampler will be retracted to the surface. The soils sampled at approximately
5-foot intervals will be Jogged using the Unified Soil Classification System
(ASTM D-2487). Soil vapors from each sample will be monitored with an organic
vapor meter (OVM). The soil will he placed in a Ziploc(TM) hag for several
minutes; the bag then will be pierced with the OVM probe in order to record the
organic vapor levels present.

Soil samples for laboratory analysis will be collected in acetate liners. The
ends of the liners will be covered in Teflon film, fitted with plastic end caps,
taped, and labeled with a unique identification number. The samples then will be
placed in an ice-chilled cooler and transported to a state-certified analytical
laboratory with chain of custody documentation.

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

GROUND WATER SAMPLING

Ground water will be collected through the direct push drive rods using a small
diameter bailer and placed in appropriate sample bottles labeled with a unique
identification number. The samples then will be placed in an ice-chilled cooler
and transposed to a state-certified analytical laboratory with chain of custody
documentation.

Sampling of Monitoring Welt MW-12: Ground .Water from the monitoring well MW-12
will be sampled in general accordance with EPA guidelines. A Teflon bailer or
submersible pump will be used to purge a minimum of three well casing volumes of
water from the well. After purging, the volume, pH, temperature, and
conductivity measurements will be recorded. In general, these measurements
stabilize (consecutive readings within 10 percent) after three to four well
volumes. If, alter the third well volume, the pH and conductivity have not
stabilized, additional well volumes will be removed until these measurements do
stabilize. if the yield is low and the well pumped dry, the well will be allowed
to recharge to the 50 percent level before sampling.

Ground water samples will be collected using a Teflon hailer and placed in
appropriate sample bottles labeled with a unique identification number. The
samples then will be placed in an ice-chilled cooler and transported to a
state-certified analytical laboratory with chain of custody documentation.

SAMPLING EQUIPMENT DECONTAMINATION

All sampling equipment will be thoroughly cleaned with an aqueous solution of
tri-sodium phosphate and distilled water or steam cleaned

Soil Cuttings, Steam Cleaning rinsate, and purged Ground Water Soil cuttings,
steam cleaning rinsate, and purged ground water will be stored on-site in EPA
approved drums. Our costs do not include handling or disposal of this material.
After receipt of the analytical results, we could provide a cost estimate for
disposal of these materials. If this is desired by you, please notify us.

LABORATORY ANALYSES

Four soil samples and two ground water samples will be analyzed at a state
certified laboratory for total petroleum hydrocarbons in the diesel range
(TPHd)(EPA Test Method 8015/8020), and volatile organic compounds (VOCs) (EPA
Test Method 8240). All analyses will be performed on a standard one-week
laboratory response time.

its report in a timely manner, but it is expressly agreed and understood by
Client that Lowney shall not be held responsible for delays occasioned by
factors beyond its control, nor by factors which could not reasonably have been
foreseen at the time of the execution of the Agreement between the parties.
Lowney will not be responsible for any damages, consequential or otherwise,
caused by delays in the completion of the Work. Lowney makes no warranties
regarding time of completion of the Work. In the event that the Work is
interrupted or delayed due to causes beyond Lowney's control including, but not
limited to, acts of God, war, riot, insurrection, inclement weather, fire acts
of third parties or governmental bodies, or matters within the control of
Client), Lowney shall be paid compensation for labor, equipment, and other costs
Lowney incurs in order to perform the Work for the Client's benefit during the
interruption or delay.

         6.3 The individual or individuals who contract with Lowney on behalf of
the Client warrant that they are duly authorized agents of the Client and are
empowered to so contract.

         6.4 Unless otherwise agreed in writing, the Client shall be entitled to
two copies of each report prepared by Lowney.

         6.5 In the event that Lowney submits a proposal including these Terms
and Conditions of Agreement, to provide professional services and the Client
authorizes the Work by means of a purchase order or other writing
("Confirmation"), it is expressly agreed that these Terms and Conditions shall
apply, and any terms, condition, or provisions appearing in the Confirmation are
void and inapplicable except to the extent the Confirmation authorizes the Work
and binds Client to this Agreement.

techniques, sequences, or procedures, or for safety precautions and programs in
connection with the job or the work of any contractor, subcontractor, or their

                                       11
<PAGE>

agents or employees, or any other person performing work or services on the job
or at the site.

8.       TERMINATION

         8.1 Either party may terminate this Agreement by giving the other party
seven (7) days' written notice. Notice shall be effective as of the date of
deposit in the U.S. Mail of the written notice, properly addressed to the person
to be notified. In the event that the Client requests termination of the
services prior to completion of Work, Lowney reserves the right to complete such
analyses and records as may be necessary to place its files in order and, where
considered necessary to protect its professional reputation, to complete a
report on the services performed to date. A termination charge of 10 percent of
the total contract amount in addition to all costs incurred to the date of Work
stoppage may be made at the discretion of Lowney.

9.       OWNERSHIP OF DOCUMENTS

         9.1 All reports, boring logs, field data, field notes, laboratory test
data, calculations, estimates and other documents prepared by Lowney, as
instruments of Work, shall remain the property of Lowney. Client agrees that all

10.      RIGHT OF ENTRY

         10.1 The Client will provide for right of entry of Lowney personnel and
all necessary equipment, in order to complete the Work. While Lowney will take
all reasonable precautions to minimize any damage to the property including
underground utilities, it is acknowledged and agreed by Client that in the
normal course of the Work some damage may occur, the correction of which is not
part of this Agreement. Accordingly, Client shall waive any claim against Lowney
and agree to defend and indemnify Lowney from any claims arising from entering
or working on the site which is the subject of the Work.

11.      MONITORING OF CONSTRUCTION

         The Client hereby acknowledges and understands that unanticipated or
changed conditions may be encountered during construction. Further, there is a
substantial risk to both the Client and to Lowney if Lowney is not engaged to
provide complete services, including but not limited to, construction
observation services. Such risks include the increased likelihood of
misinterpretation of Lowney's findings and conclusions, and error in
implementing recommendations by Lowney. Therefore, if the Client fails to retain
Lowney to provide complete services, the Client agrees to defend and indemnify
Lowney against any and all claims, damages, costs and losses arising out of or
in any way related to the Work or arising out of implementing or interpreting
Lowney's work product except when the Claim arises from the sole negligence of
Lowney or where the Claim arises from the willful, wanton, or reckless conduct
of Lowney.

12.      DISCOVERY OF UNANTICIPATED HAZARDOUS MATERIALS

         12.1 Hazardous materials or other toxic substances may exist at a site
where there is no reason known to Client to believe they could or should be
present. Lowney and Client agree that the discovery of unanticipated potentially
hazardous materials constitutes a changed condition mandating a renegotiation of
the scope of Work or termination of Work. Lowney and client also agree that the
discovery of unanticipated potentially hazardous materials may make it necessary
for Lowney to take immediate measures to protect public health, safety, and the
environment. Lowney agrees to notify Client as soon as practically possible
should unanticipated hazardous materials be encountered. Client encourages
Lowney to take any or all measures that in Lowney's professional opinion are
justified to preserve and protect the health and safety of Lowney's personnel,
the public, and the environment, and Client agrees to compensate Lowney for the
cost of such services. Further, the Client agrees to defend and indemnify Lowney
from any and all claims, damages, costs, and losses arising out of or in any way
related to subsurface sampling, including, but not limited to, claims, damages,
costs and losses arising from cross-contamination except when the Claim arises
from the sole negligence of Lowney or where the Claim arises from the willful,
wanton, or reckless conduct of Lowney.

13.      CONTAMINATION OF A WATER-BEARING ZONE

         13.1 Subsurface sampling may result in unavoidable contamination of
certain subsurface areas, as when a probe or boring is advanced or drilled
through a contaminated area, into a clean soil or a water-bearing zone. Because
of the risks posed by such Work, and because subsurface sampling is often a
necessary part of Lowney's Work, the Client hereby agrees to waive all claims
against Lowney that in any way arise out of subsurface sampling, including
claims relating to cross-contamination.

14.      DISPOSAL OF SAMPLES AND DRILL CUTTINGS

         14.1 Lowney shall hold samples collected during the performance of its
Work no longer than 45 calendar days after issuance of any document that
includes data obtained from them unless Client advises in writing otherwise:
drill cuttings will be left on site. In the event that soil, rock, water or
drill cuttings, and/or other samples or material are contaminated or are
suspected to contain hazardous materials or other toxic substances hazardous or
detrimental to public health, safety, or the environment as defined by federal,
state or local statutes, regulations or ordinances, Lowney will, after
completion of testing, notify the Client of same in order for the Client to
arrange for the disposal of samples and materials. The Client recognizes and
agrees that Lowney at no time assumes title to said samples and/or materials.
The Client, not Lowney, remains ultimately responsible for selecting the
disposal or treatment facility to which such samples and/or materials are to be
delivered. The Client agrees to pay all costs associated with any storage,
transport, and disposal of samples and materials, and to defend and indemnify
Lowney from any and all claims arising out of or in any way related to the
storage, transport, and disposal of asbestos, hazardous or toxic substances, or
pollutants, including but not limited to, any samples and/or materials.
