     as follows:

     *    IBC will receive256,401 plus 375,000 rule 144 restricted
          shares of Infocall (OTCBB: INFE) plus 100,000 cashless

          to purchase shares of Infocall at a price of $2.40 per
          share for a period of 18 months.

     *    Client represents that it has a controlling interest in
          ITCareernet.com and will transfer to IBC 2.5% of the
          total outstanding shares of ITCareernet.com Inc.  Such
          shares shall be restricted with piggyback registration
          rights.

     *    IBC will receive 5% of the equity compensation CLIENT
          receives for any of its new clients when IBC is hired to
          perform consulting services.

     *    IBC will receive first rights of refusal to offer its
          services to CLIENT's new clients.

2.   All other terms in the Agreement not in conflict with the
above remain in full force and effect, and the Parties reaffirm all
such terms and provisions not in conflict with this Modification.

fact that the insurer has waived its right of subrogation before
the occurrence of a loss.

loss, cost, damage, or expense resulting from fire, explosion or
any other casualty or occurrence is incurred by either of the
parties to this Lease, or anyone claiming, by, through, or under it
in connection with the Premises, and (2) such party is then covered
in whole or in part by insurance with respect to such loss, cost,
damage, or expense or is required under this Lease to be so
insured, then the party so insured (or so required) hereby releases
the other party from any liability said other party may have
because of such loss, cost, damage or expense to the extent of any
amount recovered because of such insurance (or which could have
been recovered had such insurance been carried as so required) and
waives any right of subrogation which might otherwise exist in or
accrue to any person On account thereof

caused by Tenant or its agents, employees, contractors, visitors,
guests and invitees, shall be repaired at Tenant's expense. If any
such damage occurs, Landlord shall make such repairs as are
necessary, and Tenant shall pay any charge, costs or damages
Landlord so incurs.  Such charges, costs or damages shall be
Additional Rent, payable with the next due installment of Monthly
Base Rent. This provision shall be construed as an additional
remedy granted to Landlord, not to limit any of Landlord's other
rights and remedies.

business based on, arising out of, or resulting from any default
hereunder by Tenant, or from Tenant's wilful misconduct, negligence
or unlawful use of the Premises or the Property or anything
therein, including water, steam, electricity, or other facilities
or equipment.  Landlord, its agents and employees assume no
liability or responsibility whatsoever for the conduct or
operation (if the business, Tenant conducts in the Premises, and
they shall not be liable for any accident or injury to any person
or property that the conduct or operation of Tenant's business
causes. Tenant shall indemnify and hold harmless Landlord, its
agents and employees, against all such claims.

         (c)  Non Recourse Liability. Tenant agrees that if
Tenant is awarded a money judgment against Landlord, Tenant's sole
recourse for satisfaction of such judgment shall be limited to
execution against Landlord's estate and interest in the Property;
in no event shall any other assets of Landlord, or of any partner

or be subject to, such judgment, nor shall any partner of Landlord
or any other person or entity be held to have any personal
liability for satisfaction of any claims or judgments that Tenant
may have against Landlord and/or any partner of in such partner's
capacity as a partner of Landlord.

    17.  CASUALTY.

         (a)  Partial Destruction. If the Premises are
partially destroyed due to fire or other casualty during the Term
of this Lease, Landlord shall diligently proceed to repair and
restore the Premises Substantially to their condition before Such
casualty, taking into account the time Landlord requires to effect
a settlement with its insurance company, and to procure any
insurance proceeds. However, Landlord shall not be obligated to
repair, restore or replace any fixtures, improvements, furniture or
other property Tenant owns or installs. If the restoration of the
Premises is not substantially completed within one hundred and
fifty (150) days of the date of the casualty, Tenant may terminate
this Lease by giving Landlord thirty (30) days notice thereof
unless within such thirty (30) day notice period Landlord
substantially completes restoring the Premises in which event
Tenant's notice shall become ineffective and void. During the
period that Tenant is deprived of the use of the damaged portion of
the Premises, the rent for the remainder of the Premises shall be that
portion of the total rent which the area remaining that can be
Occupied bears to the total area of the Premises. Except as set
forth above, no compensation or claim or abatement of rent shall be
allowed or paid by Landlord because of inconvenience, annoyance or
injury to Tenant's business, arising from the repair of the
Premises or the Property.

         (b)  Substantial Destruction. If during the Term of
this Lease the Premises or the Building are so damaged by fire or
other casualty that either one is rendered substantially unfit for
occupancy, to be reasonably determined by Landlord, then Landlord
may elect to terminate this Lease as of the date Of Such casualty,
by giving written notice thereof to Tenant within sixty (60) days
after such date, in which case the rent and Additional Rent shall
be apportioned and paid to the date of said fire or other casualty.
If there is damage to or destruction of the Building that exceeds
twenty-five percent (25%) of the replacement value at the Building
or of the Land from any cause, whether or not the Premises are
damaged or destroyed, Landlord shall have the right to terminate
this Lease by written notice as set forth above.

                                                                  TYCON FORM

Landlord is not obligated to repair any damage thereto or to
replace the same.  In addition, Landlord is not obligated to repair
any damage or injury to, or to replace, any Leasehold Improvements
or Alterations made or installed in the Premises.

    18.  CONDEMNATION.

         (a)  Substantial Condemnation. Tenant agrees that if
the entire or a substantial part of the Premises, or the use or
occupancy thereof, are taken or condemned, for public or quasi-
public use or purpose by any competent authority, or sold under the
threat of condemnation to any competent authority, this Lease will
terminate as of the date of any such taking and all rent payable
hereunder shall be apportioned as of that date. Tenant shall have
no claim against Landlord and shall have no claim or right to any
portion of any award, damages or other compensation made to
Landlord because of any such taking or condemnation, or sale under
the threat of such a taking. Tenant hereby assigns to Landlord all
of Tenant's rights, if any, to such awards, damages and
compensation therefor.  Upon Such condemnation or taking." the Term
of this Lease shall terminate as of the date of such taking or
condemnation, and Tenant shall have no claim against Landlord for
the value of any unexpired Term of this Lease, Leasehold
Improvements, the loss of profits or good will, or severance
damages. Notwithstanding the foregoing, Tenant may pursue a
separate claim against the condemning authority, provided that any
award to Tenant does not diminish any award made to Landlord.

         (b)  Partial Condemnation. If less than a Substantial part of
the Premises is taken or condemned, the rent for the remainder of
the Premises shall be that portion of the total rent which the area
remaining that can be occupied bears to the total area of the
Premises, effective on the date when title vests in Such
governmental authority. The Lease shall otherwise remain in full
force and effect. For purposes hereof, a substantial part of the
Premises shall be considered to have been taken if more than one-
third (1/3) of the rentable area of the Premises is rendered
unusable as a result of such condemnation. Notwithstanding anything
to the contrary herein contained, if twenty-five percent (25%) or
more of the Building or of the Land is taken, condemned or sold
under the threat of such a taking, Landlord may, at its sole
option, terminate this Lease as of the date of the taking.

              (ii)  If Tenant abandons or vacates the Premises; or

                                15
                                                                  TYCON FORM

tenders possession of the Premises to Tenant; or

              (iv)  If Tenant fails to observe or perform any of
its obligations under the provisions of this Lease to be observed
or performed by Tenant (except a term, covenant or condition, the
observation or performance of which is otherwise dealt with in this
section 19(a)), and, such failure continues for a period of thirty
(30) days after written notice thereof by Landlord to Tenant;
provided, however, that if such default is nonmonetary and cannot
reasonably be Cured within thirty (30) day period, then the default
shall not be deemed to be uncured if Tenant commences to mire
within thirty (30) day period from Landlord's notice and continues
to prosecute diligently the completion of cure thereof within a
reasonable time not to exceed ninety (90) days; or

              (v)   If Tenant makes any general assignment or
general arrangement for the benefit of creditors; if there is filed
by or against Tenant a petition to have Tenant adjudged a bankrupt
or if a petition for reorganization or arrangement is filed under
any law relating to bankruptcy (unless, in the case of a petition
filed against Tenant, the same is dismissed within sixty (60)
days); if a trustee or receiver is appointed to take possession of
all or substantially all of Tenant's interest in this Lease, if all
or substantially all of Tenant's assets located at the Premises or
Tenant's interest in this Lease are attached, executed upon or
otherwise Subjected to other judicial seizure, where such seizure
is not discharged within thirty (30) days; or if Tenant is
generally not paying its debts as they become due; provided,
however, in no event shall this Lease be assigned or assignable by
operation of law or by voluntary or involuntary bankruptcy
proceedings or otherwise, and in no event shall this Lease or any
rights or privileges hereunder be an asset of Tenant under any
bankruptcy, insolvency, reorganization or other debtor relief
proceedings; or

              (vi)   If Tenant fails to pay the Monthly Base

three (3) times during any calendar year (even if Tenant cures each

              (vii)  If a Transfer occurs in violation of any
provision contained in this Lease.

         (b)  Landlord's Rights and Remedies in Event of

thereafter, in its sole discretion, without limiting Landlord's
exercise of any other right or remedy Landlord has under this
Lease, at law or in equity, because of such default or breach,
exercise the following, rights:

              (i)    Landlord may terminate this Lease and
Tenant's right of possession of the Premises upon written notice to
Tenant, effective on the date specified in such notice, and recover
(a) all damages to which Landlord is entitled under law, including,
without limitation, all rental concessions, repair and alteration
costs, brokerage commissions, legal fees and other expenses of
reletting the Premises; or (b) the total amount of Base Rent and
Additional Rent payable under this Lease from the date of
termination until the Lease Expiration Date. Upon such termination,

                                16
                                                                  TYCON FORM

<PAGE>   Exhibit - 10.19

every obligation of the parties shall cease as of the date of
termination, except that Tenant shall remain liable to pay all rent
and other sums accrued up to the date of termination or recovery of
possession by Landlord, whichever is later, and to perform all
terms and obligations of this Lease which expressly survive
termination hereof.  The notice of termination  provided hereunder
shall operate as a notice to quit, and Tenant waives any other
notice to quit or notice of Landlord's intention to re-enter the
Premises; or

              (ii)   Without terminating this Lease and without
entering into possession of the Premises, Landlord may continue
this Lease in effect and to enforce all Landlord's rights and
Tenant's obligations hereunder, including filing suit to collect
Monthly Base Rent, Additional Rent, and all other Sums due
hereunder as they accrue (including attorneys' fees and other
damages). Acts of maintenance or preservation, efforts to relet the
Premises, or appointing a receiver upon Landlord's initiative to
protect its interest under this Lease shall not constitute a
termination of this Lease or Tenant's right to possession hereunder;
or

              (iii)  Without terminating this Lease, Landlord may
reenter and retake possession of the Premises and any and all
Leasehold Improvements from Tenant by summary proceedings or
otherwise, and remove, or cause to be removed, Tenant or any other
occupants from the Premises in such a manner as Landlord deemed is
appropriate, with or without legal process and using self-help, if
deemed appropriate by Landlord. The commencement and prosecution of
any action by Landlord in unlawful detainer, ejectment or
otherwise, or any execution of any judgment or decree obtained in
any action to recover possession of the Premises, or any other re-
entry and removal, shall not constitute a termination of this
Lease, and shall not be deemed to have absolved or discharged
Tenant from  any of its obligations or liabilities for the
remainder of the Term, nor shall Landlord be liable for the
prosecution therefor, or be deemed guilty of any trespass. Tenant
shall, notwithstanding any such entry or re-entry, remain liable to
pay rent and perform the other covenants, conditions and agreements
by Tenant to be performed as set forth in this Lease. Thereafter,
Landlord shall have the right, and shall use reasonable efforts, to
relet the Premises for Tenant's account, in whole or in part, or
together with other space, for such Term or Terms (which may be
greater or less than or equal to the unexpired portion of the Term)
upon such provisions (including concessions) and for such rental as
Landlord in its sole discretion determines appropriate, and to
collect and receive said rental. Landlord shall not be liable for,
nor shall Tenant's obligations hereunder be diminished because of,
any failure of Landlord to relet the Premises or any failure of
Landlord to collect all rent due upon such reletting. If and when
the Premises are relet a sufficient sum is not realized from such
reletting, after paying all Landlord's expenses of reletting
(including, without limitation, rental concessions, brokerage
commissions, legal fees, repairs and alterations), to satisfy
Tenant's obligations to pay Monthly Base Rent and Additional Rent
hereunder, Tenant shall pay any deficiency to Landlord on demand.
Tenant shall have no right to any excess rent that Land lord
recovers because of such reletting. No notice from Landlord
hereunder or under a forcible entry and detainer statute or similar
law shall constitute an election by Landlord to terminate this
Lease unless Such notice specifically so states. Landlord reserves
the right following any such re- entry and/or reletting to
terminate this Lease by giving Tenant such written notice, in which
event this Lease will terminate as specified in said notice.

              (iv)   Landlord may, but shall not be obligated,
remove from the Premises all or any part of any personal property
located therein and to sell such property and apply the proceeds to
any damages Landlord incurs, or to place the same in storage at a
public warehouse at the expense and risk of the owner or owners
thereof, without liability therefor.

              (v)    Landlord may cure such Event of Default in
any other manner, in which event Tenant shall reimburse Landlord
for all expenses Landlord incurs in doing so, plus interest thereon
at rate of eighteen percent (18%) per annum, or the maximum rate
permitted by law, whichever is less, which expenses and interest
shall be Additional Rent payable by Tenant immediately upon
Landlord's demand.

              (vi)   In addition to the foregoing, Landlord may
recover from Tenant as damages any other amount necessary to
compensate Landlord for all the detriment proximately caused by
Tenant's failure to perform its obligations under this Lease or
which in the ordinary course of events would be likely to result
there from, including without limitation, commissions, advertising
costs, costs of Leasehold Improvements, costs of making any
alterations or repairs in the Premises and reasonable attorneys'
fees, and, to the extent permitted by law, the value and/or cost of
all concessions to Tenant under this Lease (including without
limitation, rental abatements, allowances, and assumption of rental
obligations to third parties); and

              (vii)  Landlord may pursue any individual remedy
or any combination of the remedies set forth in this subsection (b).

         (c)  Legal Action. Landlord may, at its election, bring.,
a suit or suits to recover the amounts and damages set forth above,
and nothing herein shall be deemed to require Landlord to await the
date whereon this Lease or the Term hereof would have expired by
limitation had there been no such default by Tenant or no such
termination, as the case may be. Each right and remedy provided for
in this Lease is cumulative and in addition to every other right or
remedy provided for in this Lease or now or hereafter existing at
law or in equity or by statute or otherwise  including, but not
limited to, suits for injunctive relief and specific performance.
The exercise or beginning of the exercise by Landlord of any one or
more of the rights or remedies provided for in this Lease or now or
hereafter existing at law or in equity or by statute or otherwise
shall not preclude Landlord's simultaneous or later exercise of any
and all other rights or remedies provided for in this Lease or now
or hereafter existing at law or in equity or by statute or
otherwise. Landlord may also recover from Tenant all costs Landlord
incurs in collecting any amounts or damages Tenant owes pursuant to
the provision of this Lease, including reasonable attorneys' fees
from the date any such matter is turned over to an attorney.

         (d)  Injunctive Relief. If Tenant breaches or threatens
to breach any of the covenants or provisions of this Lease,
Landlord shall have the right of injunctive relief and the right
to invoke any remedy allowed at law or in equity; and in such event
Landlord shall be entitled to recover from Tenant, payable as
Additional Rent hereunder, any and all reasonable expenses Landlord
incurs in its efforts to secure such injunctive relief or other
remedy at law or in equity, such as Court costs and attorneys'
fees.

         (e)  Independent Obligations. If Landlord commences any
proceeding for non- payment of rent, or any other payment of any
kind to which Landlord is entitled or which it may claim hereunder,
Tenant shall not interpose any counterclaim or set-off of whatever
nature or description in any such proceeding, the parties hereto
specifically agreeing that Tenant's covenants to pay rent or to
make any other payments required of it hereunder are independent of
all other covenants and agreements herein contained, provided,
however, that this shall not be construed as a waiver of Tenant's
right to assert such a claim in any separate action brought by
Tenant. Tenant further waives any right or defense which it may
have to claim a merger, and neither the commencement of any
action or proceeding, nor the settlement thereof, nor entering of
judgment therein, shall bar Landlord from bringing subsequent
actions or proceedings from time to time. Tenant expressly waives
any and all right of redemption granted by or under any present or
future laws if Tenant is evicted or dispossessed for any cause, or
if Landlord obtains possession of the Premises because Tenant
violates any of the covenants and conditions of this Lease, or
otherwise.

         (f)  Compromise or Settlement.  If legal proceedings are
instituted hereunder, and a compromise or settlement thereof is
made, it shall not be constituted as a waiver of any subsequent
breach of any covenant, condition or agreement herein contained.

         (g)  Acceptance of Payment. No payment by Tenant or
receipt by Landlord of a lesser amount than the Monthly Base Rent
herein stipulated shall be deemed to be other than on account of
the earliest stipulated rent then due, nor shall any endorsement or
statement on any check or any letter accompanying any check or
payment of rent be deemed an accord and satisfaction, and Landlord
may accept such check or payment without prejudice to Landlord's
right to recover the balance of such rent or to pursue any other
remedy.

         (h)  Repudiation. If, before the commencement of the Term
of this Lease, Tenant notifies Landlord of, or otherwise
unequivocally demonstrates an intention to, repudiate this Lease,
Landlord may, at its option, consider such anticipatory repudiation
a breach of this Lease. In addition to any other remedies available
to it hereunder or at law or in equity, Landlord may retain all
rent paid upon execution of the Lease, and the Security deposit, if
any, to be applied to damages of Landlord incurred as a result of
such repudiation, including, without limitation, attorneys' fees,
brokerage fees, costs of re-letting and loss of rent. The parties
agree that for the purpose of calculating Landlord's damages, in a
building which has other available space at the time of Tenant's
breach, Landlord shall have no obligation to rent the Premises
before other space in the Building.

         (i)  Landlord's Lien. Landlord shall have a lien upon
Tenant's property in the Premises during the Lease Term for the
amount of any unpaid rent or other sum due from Tenant hereunder.
Landlord shall have the right and privilege, at its sole option and
discretion, to take possession of all Tenant's property in the
Premises, to store the same in the Premises, or to remove it from
the Premises and store it in such place as Landlord may select, at
Tenant's risk and expense, in accordance with Such lien and of any
rights of distraint Landlord may possess against Tenant's property.
Provided, however, so long as Tenant is not in default hereunder,
Landlord will Subordinate the lien set forth in this subsection (i)
to any purchase money financing or personal property leases
requested by Tenant.

    20.  SUBORDINATION

         (a)  Subordination of Lease.  This Lease is subordinate
to the lien, operation and effect of all ground leases, deeds of
trust, mortgages, and/or other similar instruments of  encumbrance
(herein each referred to for the purposes of this Section 20 as
"Mortgages") which may now or hereafter affect this Lease or the
Property, to all funds and all indebtedness intended to be secured
by such Mortgages, and to all renewals, modifications,
consolidations, replacements and extensions thereof This clause
shall be self-operative and no further instrument of subordination
shall be necessary to effect the subordination of this Lease to the
lien of any such Mortgage. In confirmation of such Subordination,
Tenant shall, within five (5) days of the written request of
Landlord or the holder of any Mortgage, execute promptly any
further instruments requested. Tenant constitutes and appoints
Landlord as Tenant's attorney-in-fact to execute any such
instruments for or on Tenant's behalf if Tenant fails to execute
and deliver such instrument(s) within said five (5) day period.

         (b)  Foreclosure. If any proceeding is instituted to
terminate or to foreclose upon any Mortgage to which this Lease is
subordinate, the ground lessor, purchaser, assignee or other
successor to Landlord's rights shall have the option to terminate
or cancel this Lease. If this Lease is not so terminated or
cancelled, Tenant shall attorn o the purchaser at the foreclosure
sale and shall recognize such purchaser as the landlord pursuant to
this Lease. Upon request by such purchaser, Tenant shall execute
and deliver an instrument or instruments confirming its attornment.

         (c)  Modifications Required by Lender. If any lender
providing any financing for the Building requires, as a condition
of that financing, that modifications to the Lease be obtained, and
provided that the modifications do not increase the rent and other
sums to be paid by Tenant hereunder nor materially affect Tenant's
use of the Premises, Landlord may submit to Tenant a written
amendment to the Lease incorporating the required changes, and
Tenant shall execute, acknowledge and deliver such amendment to
Landlord within five (5) days of Tenant's receipt thereof.

         (d)  Subordination of Mortgage to Lease. Anything
contained in the provisions of this Section to the contrary
notwithstanding, the holder of any Mortgage may at any time
subordinate the lien of its Mortgage to the operation and effect of
this Lease without obtaining Tenant's consent thereto, by giving
Tenant written notice thereof, in which event this Lease shall be
deemed to be senior to such Mortgage without regard to their
respective dates of execution, delivery and/or recordation, and
thereafter such Mortgagee shall have the same rights, as to this
Lease as it would have had, were this Lease executed and delivered
and/or recorded before the execution of such Mortgage.
