                  AMERICAN INDUSTRIAL REAL ESTATE ASSOCIATION
                               STANDARD SUBLEASE
                (Long-form to be used with pre-1996 AIR leases)


1.  Parties.  This Sublease, dated, for reference purposes only, October 22,
1999, is made by and between Thermatrix Inc.  ("Sublessor") and TrueLinks, inc.,
a California corporation ("Sublessee").

2.  Premises.  Sublessor hereby subleases to Sublessee and Sublessee hereby
subleases from Sublessor for the term, at the rental, and upon all of the
conditions set forth herein, that certain real property, including all
improvements therein, and commonly known by the street address 2025 Gateway
Place, Suite 132, San Jose, located in the County of Santa Clara, State of
California and generally described as (describe briefly the nature of the
property) a 4,464 rentable square foot office suite in an approximately 158,000
square foot office building.   ("Premises").

3.  Term.
     3.1  Term.  The term of this Sublease shall be for Twelve (12) months
commencing on November 1, 1999 and ending on October 29, 2000 unless sooner
terminated pursuant to any provision hereof.
     3.2  Delay in Commencement.  Sublessor agrees to use its best commercially
reasonable efforts to deliver possession of the Premises by the commencement
date.  If, despite said efforts, Sublessor is unable to deliver possession as
agreed, Sublessor shall not be subject to any liability therefor, nor shall such
failure affect the validity of this Sublease.   Sublessee shall not, however, be
obligated to pay Rent or perform its other obligations until it receives
possession of the Premises.   If possession is not delivered within sixty days
after the commencement date, Sublessee may, at its option, by notice in writing
within ten days after the end of such sixty day period, cancel this Sublease, in
which event the Parties shall be discharged from all obligations hereunder.  If
such written notice is not received by Sublessor within said ten-day period.
Sublessee's right to cancel shall terminate.  Except as otherwise provided, if
possession is not tendered to Sublessee when required and Sublessee does not
terminate this Sublease, as aforesaid, any period of rent abatement that
Sublessee would otherwise have enjoyed shall run from the date of delivery of
possession and continue for a period equal to what Sublessee would otherwise
have enjoyed under the terms hereof, but minus any days of delay caused by the
acts of omissions of Sublessee.   If possession is not delivered within 120 days
after the commencement date, this Sublease shall automatically terminate unless
the Parties agree, in writing, to the contrary.

4.  Rent.
     4.1   Base Rent.  Sublessee shall pay to Sublessor as Base Rent for the
Premises equal monthly payments of $11,383.20, in advance, on the first day of
each month of the term hereof.  Sublessee shall pay Sublessor upon the execution
hereof $11,383.20 as Base Rent for November 1, 1999 through November 30, 1999
Base Rent for any period during the term hereof which is for less than one (1)
month shall be pro rata portion of the monthly installment.
     4.2  Rent Defined.  All monetary obligations of Sublessee to Sublessor
under the terms of this Sublease (except for the Security Deposit) are deemed to
be rent ("Rent").  Rent shall be payable in lawful money of the United States to
Sublessor at the address stated herein or to such other persons or at such other
places as Sublessor may designate in writing.

5.  Security Deposit.  Sublessee shall deposit with Sublessor upon execution
hereof $11,383.20 as security for Sublessee's faithful performance of
Sublessee's obligations hereunder.  If Sublessee fails to pay Rent or other
charges due hereunder, or otherwise defaults with respect to any provision of
this Sublease, Sublessor may use, apply or retain all or any portion of said
deposit for the payment of any Rent or other charge in default or for the
payment of any other sum to which Sublessor may become obligated by reason of
Sublessee's default, or to compensate Sublessor for any loss or damage which
Sublessor may suffer thereby.  If Sublessor so uses or applies all or any
portion of said deposit, Sublessee shall within ten (10) days after written
demand therefore deposit cash with Sublessor in an amount sufficient to restore
said deposit to the full amount hereinabove stated and Sublessee's failure to do
so shall be a material breach of this Sublease.  Sublessor shall not be required
to keep said Deposit separate from its general accounts.  If Sublessee performs
all of Sublessee's obligations hereunder, said Deposit, or so much thereof as
has not therefore been applied by Sublessor, shall be returned, without payment
of interest to Sublessee (or at Sublessor's option, to the last assignee, if
any, of Sublessee's interest hereunder) at the expiration of the term hereof,
and after Sublessee has vacated the Premises.  No trust relationship is created
herein between Sublessor and Sublessee with respect to said Security Deposit.

6.  Use.
     6.1  Agreed Use.  The Premises shall be used and occupied only for general
office purposes.
     6.2  Compliance.  Sublessor warrants to that the improvements on the
Premises comply with all applicable covenants or restrictions of record and
applicable building codes, regulations and ordinances ("Applicable
Requirements") in effect on the commencement date.  Said warranty does not apply
to the use to which Sublessee will put the Premises to any alterations or
utility installations made or to be made by Sublessee.  NOTE:  Sublessee is
responsible for determining whether or not the zoning is appropriate for its
intended use, and acknowledges that past uses of the Premises may no longer be
allowed.  If the Premises do not comply with said warranty, Sublessor shall,
except as otherwise provided, promptly after receipt of written notice from
Sublessee setting forth with specificity the nature and extent of such non-
compliance, rectify the same at Sublessor's expense.  If Sublessee does

                                  Page 1 of 6
<PAGE>

not give Sublessor written notice of a non-compliance with this warranty within
six months following the commencement date, correction of that non-compliance
shall be the obligation of Sublessee at its sole cost and expense. If the
Applicable Requirements are hereafter changed so as to require during the term
of this Sublease the construction of an addition to or an alteration of the
Building, the remediation of any Hazardous Substance, or the reinforcement or
other physical modification of the Building ("Capital Expenditure"), Sublessor
and Sublessee shall allocate the cost of such work as follows:
          (a) If such Capital Expenditures are required as a result of the
specific and unique use of the Premises by Sublessee as compared with uses by
tenants in general. Sublessee shall be fully responsible for the cost thereof
provided, however, that if such Capital Expenditure is required during the last
two years of this Sublease and the cost thereof exceeds six months' Base Rent,
Sublessee may instead terminate this Sublease unless Sublessor notifies
Sublessee in writing, within ten days after receipt of Sublessee's termination
notice that Sublessor has elected to pay the difference between the actual cost
thereof and the amount equal to six months' Base Rent. If the Parties elect
termination, Sublessee shall immediately cease the use of the Premises which
requires such Capital Expenditure and deliver to Sublessor written notice
specifying a termination date at least ninety days thereafter. Such termination
date shall, however, in no event be earlier than the last day that Sublessee
could legally utilize the Premises without commencing such Capital Expenditure.
          (b) If such Capital Expenditure is not the result of the specific and
unique use of the Premises by Sublessee (such as governmentally mandated seismic
modifications, then Sublessor shall pay for said Capital Expenditure and the
cost thereof shall be prorated between the Sublessor and Sublessee and Sublessee
shall only pay for said Capital Expenditure and the cost thereof shall be
prorated between the Sublessor and Sublessee and Sublessee shall only be
obligated to pay, each month during the remainder of the term of this Sublease,
on the date on which Rent is due, an amount equal to the product of multiplying
the cost of such Capital Expenditure by a fraction, the numerator of which is
one, and the denominator of which is the number of months of the useful life of
such Capital Expenditure as such useful life is specified pursuant to Federal
income tax regulations or guidelines for depreciation thereof (including
interest on the unamortized balance as is then commercially reasonable in the
judgment of Sublessor's accountant), with Sublessee reserving the right to
prepay its obligation at any time.  Provided, however, that if such Capital
Expenditure is required during the last two years of this Sublease or if
Sublessor reasonably determines that it is not economically feasible to pay its
share thereof.  Sublessor shall have the option to terminate this Sublease upon
ninety days prior written notice to Sublessee unless Sublessee notifies
Sublessor, in writing, within ten days after receipt of Sublessor's termination
notice that Sublessee will pay for such Capital Expenditure.  If Sublessor does
not elect to terminate, and fails to tender its share of any such Capital
Expenditure, Sublessee may advance such funds and deduct same, with interest,
from Rent until Sublessor's share of such costs have been fully paid.  If
Sublessee is unable to finance Sublessor's share, or if the balance of the Rent
due and payable for the remainder of this Sublease is not sufficient to fully
reimburse Sublessee on an offset basis, Sublessee shall have the right to
terminate this Sublease upon ten days written notice to Sublessor.
          (c) Notwithstanding the above, the provisions concerning Capital
Expenditures are intended to apply only to non-voluntary, unexpected, and new
Applicable Requirements.   If the Capital Expenditures are instead triggered by
Sublessee as a result of an actual or proposed change in use, change in
intensity of use, or modification to the Premises then, and in that event,
Sublessee shall be fully responsible for the cost thereof, and Sublessee shall
not have any right to terminate this Sublease.
     6.3  Acceptance of Premises and Lessee.  Sublessee acknowledges that:
          (a) It has been advised by Brokers to satisfy itself with respect to
the condition of the Premises (including but not limited to the electrical, HVAC
and fire sprinkler systems, security, environmental aspects, and compliance with
Applicable Requirements), and their suitability for Sublessee's intended use.
          (b) Sublessee has made such investigation as it deems necessary with
reference to such matters and assumes all responsibility therefor as the same
relate to its occupancy of the Premises, and
          (c) Neither Sublessor, Sublessor's agents, nor any Broker has made any
oral or written representations or warranties with respect to said matters other
than as set forth in this Sublease.

In addition, Sublessor acknowledges that:
          (a) Broker has made no representations, promises or warranties
concerning Sublessee's ability to honor the Sublease or suitability to occupy
the Premises, and
          (b) It is Sublessor's sole responsibility to investigate the financial
capability and/or suitability of all proposed tenants.

and Sublease dated May 7, 1998, that Sublessor may receive, collect and enjoy

the performance of its obligations to Master Lessor then Master Lessor may, at
its option, receive and collect, directly from Sublessee, all Rent owing and to

due under the Sublease.  Sublessor agrees that Sublessee shall have the right to
rely upon any such statement and request from Master Lessor, and that Sublessee
shall pay such Rent to Master Lessor without any obligation or right to inquire
as to whether such Default exists and notwithstanding any notice from or claim
from Sublessor to the contrary and Sublessor shall have no right or claim
against Sublessee for any such rents so paid by Sublessee.

to this Sublease.
     9.3  In the event that Master Lessor does give such consent then:

          (b) The acceptance of Rent by Master Lessor from Sublessee or anyone

deemed a waiver by Master Lessor of any provisions of the Master Lease and
Sublease dated May 7, 1998.
          (c) The consent to this Sublease shall not constitute a consent to any
subsequent subletting or assignment.
          (d) In the event of any Default of Sublessor under the Master Lease
and Sublease dated May 7, 1998, Master Lessor may proceed directly against

Lessor's remedies against any other person or entity liable thereon to Master
Lessor.
          (e) Master Lessor may consent to subsequent sublettings and
assignments of the Master Lease and Sublease dated May 7, 1998 or this Sublease

<PAGE>

under the Master Lease and Sublease dated May 7, 1998 and without obtaining
their consent and such action shall not relieve such persons from liability.
          (f) In the event that Sublessor shall Default in its obligations under
the Master Lease and Sublease dated May 7, 1998, then Master Lessor, at its
option and without being obligated to do so, may require Sublessee to attorn to
Master Lessor in which event Master Lessor shall undertake the obligations of
Sublessor under this Sublease from the time of the exercise of said option to

default.  Sublessee shall have the right to cure any default of Sublessor
described in any notice of default within ten (10) days after service of such

Sublessee shall have the right of reimbursement and offset from and against
Sublessor.

substantially similar thereto, either to extend the term of this Sublease, to
