                          Systems Integrator Agreement

This System Integrator Agreement (the "Agreement"), effective April 4, 2003
("Effective Date"), is made between mPhase Technologies, Inc., a New Jersey
corporation with offices at 587 Connecticut Avenue, Norwalk, CT 06854
("Customer"), and Lucent Technologies Inc., a Delaware corporation with offices
at 600 Mountain Ave., Murray Hill, New Jersey 07914 ("Lucent") (each a "Party"
and collectively the "Parties").

In consideration of their mutual promises and undertakings, the Parties agree as
follows:

1. SCOPE: This Agreement describes the terms and conditions under which Lucent
shall sell, and Customer shall purchase, Products and Licensed Materials, and
related services, for the purpose of selling the Product and Licensed Material
as part of a Bundled Offer by Customer to its End User customers. Bundled Offer
as used herein shall mean a product offering made by Customer to its End User
customers consisting of the Products or Licensed Materials combined with other
products manufactured or services performed by Customer, the combination of
which will add additional value to End Users of the Products and Licensed
Materials. This Agreement also covers the licensing of Licensed Materials to
Customer for use and sub-licensing as specified in this Agreement. The only
Products and Licensed Materials covered by this Agreement are those listed in
Exhibit B. Sale of Products or Licensed Materials is limited to End Users
located and doing business within the United States. Resale to any End User
customers outside of the United States is prohibited under this Agreement.
Notwithstanding the above, Customer may export the Products and Licensed
Materials to its End User customers outside the United States provided that the
Products and Licensed Materials are (1) being exported in connection with and
as part of a sale by Customer of a Bundled Offer and (2) such export is done in
accordance with Section 16 entitled "Export". Stand-alone resale of the Products
or Licensed Materials not in connection with the sale by Customer of a Bundled
Offer is prohibited. Customer agrees that it has no exclusive right to market
the Products or Licensed Materials incorporated herein, and that no franchise is
granted herein. No payment of any fee or similar charge is required as a
condition of this Agreement. All references to the "Agreement" shall be deemed
to include this document and its exhibit together with any and all Addenda and
their attachments. Exhibit A contains the definitions of certain
capitalized terms used in this Agreement. Customer shall market the Products and
Licensed Materials to End User customers on such terms and conditions as
Customer chooses, provided Customer does not violate this Agreement.

2. TERM: This Agreement shall begin on the Effective Date and shall continue for
a period of two year ("Term"), with an option to extend an additional year upon
written agreement between the Parties, unless earlier terminated as provided in
"Termination" below or as mutually agreed in writing. Termination or expiration
of this Agreement shall not excuse a Party from performing obligations that have
not been fully performed for any accepted Order.

3. ORDERS AND FORECASTS: All purchases under this Agreement shall be made by
Orders issued by Customer from time to time subject to acceptance by Lucent.
Lucent reserves the right to place any Order on hold, delay shipment, suspend
performance, and/or reject any Order due to, but not limited to: (a) the breach
or default by Customer of any of its obligations under this Agreement; (b)
CUstomer's insufficient credit as determined by Lucent. Orders that have been
accepted by Lucent may not be canceled without the express written consent of
Lucent. Each Order shall reference this Agreement and shall be subject only to
the terms and conditions of this Agreement. Terms and conditions contained in an
Order that are inconsistent with this, including any pre-printed terms and
conditions on such Order, shall be ineffective and void. Customer shall send
Orders to the address specified by Lucent.

Customer shall provide Lucent with a rolling twelve (12) month non-binding
forecast of product requirements, including configuration. Customer shall
provide the initial forecast within one week of the date of this Agreement, and
thereafter shall update the forecast at least monthly.

4. CHANGES TO ORDERS: Customer may request changes to an Order ("Change
Request") that Lucent has previously accepted. In response to a Change Request,
Lucent will provide written quotations, including any changes to prices, license
fees, shipment or completion dates. A Change Request will be treated as a
separate Order subject to Lucent's change order process.

5. CHANGES IN PRODUCTS OR SOFTWARE: At any time prior to shipment, Lucent may
make changes to Products or Software. Lucent may modify the drawings,
documentation or Specifications for Products or Software or substitute Products
or Software of later design. If such changes impact a Product's or Software's
form, fit or function, under normal use as provided in the Specifications,
Lucent shall notify Customer at least 30 days prior to the date the change takes
effect. If Customer objects to the change, Customer shall notify Lucent within
30 days of the date of Lucent's notice. On receipt of Customer's notice, Lucent
shall not fulfill any Orders in process with the modified Product or Software to
which Customer has objected.

6. PRICES AND TAXES: The applicable prices and discounts for each Order shall be
set forth in Exhibit B. Such discounts shall be applied to Lucent's List Price
in effect at the time of order receipt. All discounts shown in Exhibit B are not
applicable to related Services such as engineering and installation. Pricing and
discounts

contained within Exhibit B are applicable to sales in the United States only.
Lucent may adjust its prices and charges upon 30 days prior written notice to
Customer. If, however, Lucent's adjustment in price is due to changes in raw
material prices, Lucent's price adjustment will be effective on the first day of
the next calendar month. The prices and charges are based on Lucent's standard,
published intervals for shipping, planning or completion, unless Lucent
otherwise agrees in writing. Except for taxes on Lucent's income, Customer shall
pay all applicable taxes and related charges, including interest and penalties,
that any governmental or taxing authority may impose upon the purchase, license,
ownership, possession, use, operation or relocation of any Products or Software
that Lucent furnishes under this Agreement.

7. TERMS OF PAYMENT: Payment for Products, Licensed Materials or Services
(including transportation charges and taxes) will be due as follows:

(a)   Each order for Products and/or Licensed Materials only shall be
      accompanied by advance payment equal to 100% of the value of the Order.
(b)   Each Order for Services shall be accompanied by advance payment equal to
      100% of the total value of the Order for such Services.

Customer will advise Lucent of any billing discrepancies or disputes about an
invoice within 10 days after receiving it. Overdue payments (but not amounts
disputed in good faith) shall be subject to a late payment charge of 1 1/2% per
month of the overdue amount (but not to exceed the maximum lawful rate).
Customer will reimburse Lucent for reasonable attorneys' fees and other costs
associated with collecting delinquent payments.

Customer shall pay all amounts due Lucent hereunder using electronic funds

advance payments. EFT payments by Customer shall be made to the following

8. TITLE AND RISK OF LOSS: Title to Products only, and risk of loss and damage
to Products and Licensed Materials, shall pass to Customer upon shipment. Lucent
retains title to all Licensed Materials and all copies thereof.

GRANT OF LICENSE: a. Upon delivery of Licensed Materials and subject to the
provisions of this Agreement, Lucent grants Customer a personal, nontransferable
and nonexclusive license to use the Licensed Materials on or with the
corresponding Product(s) (on which the Software was loaded or designated by
Lucent to be loaded) for Customer's sublicense to its End Users, per the terms
and conditions of this section. If the Product(s) on which the Software was
loaded or designated by Lucent to be loaded become inoperative, Customer may use
the Software on an alternate processor, but must purchase a separate Right to
Use license to install on the inoperative processor, once it is restored to
working order. Customer shall not copy Licensed Materials except for backup and
archival purposes. Customer shall reproduce and include Lucent's copyright and
proprietary notice on all sublicensed Lucent Licensed Materials. Customer shall

discretion, electronically audit Software provided under this Agreement to
verify compliance with the license provisions of this Agreement.

b. If Customer's license is canceled or terminated, or when Customer no longer
uses the Licensed Materials, Customer shall return or destroy the Licensed
Materials and all copies in its possession, and certify to Lucent that it has
done so.

c. Notwithstanding the provisions of this section, Customer may sublicense its
right to use Licensed Materials to an End User customer, but only in connection
with the sale or lease to such customer of the Products for which such Licensed
Materials were furnished. Customer will bind the End User customer to comply
with the license requirements by delivering Software that has a shrink wrap
license in the original packaging to the End User customer, with the shrink wrap
unaltered or enter into a written agreement with the End User customer no less
restrictive than the terms of the license terms contained herein. Such written
agreement shall be executed by Customer's End User customer, and shall
incorporate the terms and conditions set forth in this section except that i)
such sublicense shall not permit the End User customer to sublicense the
Licensed Materials or assign such sublicense. Upon request by Lucent, Customer
agrees to provide Lucent's independent auditor with copies of all such
sublicenses. The terms of such sublicenses shall survive any termination of
rights under this Agreement.

10. WARRANTIES: Unless a Lucent manufacturer's limited warranty accompanies the
Product, Customer shall pass through to its End User customers Lucent's warranty
as set forth in Exhibit C, "WARRANTY FOR PRODUCTS, LICENSED MATERIALS AND
SERVICES WARRANTY" which is attached hereto and incorporated by reference
herein. Lucent's sole and entire liability with regard to the Products and
Licensed Materials sold or licensed hereunder is to attempt first to repair or
replace such Product or Licensed Material without charge at its manufacturing or
repair facility or, if repair or replacement is not feasible, then provide a
refund or credit equal to the original purchase price. Where refund or credit of
the original purchase price is Lucent's only feasible option, Customer shall
cooperate with Lucent to facilitate the issuance of the appropriate credit or
refund back to Customer End User customer.

them so that they will be free of the infringement; or will procure for Customer

                                    Exhibit C

              Warranty For Products, Licensed Material and Services

Customer shall extend to the End User customer the following warranty:

a. During the Warranty Period, Lucent warrants to Customer only that during the
Warranty Period (i) Products manufactured by Lucent will be free from defects in
material and workmanship and will conform to the Specifications for such
Products while Products purchased by Lucent pursuant to its procurement
specifications will include a Warranty Period equal to that offered by the
manufacturer, unless otherwise specifically stated by Lucent; (ii) Software
developed by Lucent will be free from those defects which materially affect
performance in accordance with the Specifications. With respect to Products or
Software or partial assembly of Products furnished by Lucent but not
manufactured by Lucent, Lucent hereby assigns to Customer and/or End User
customer, to the extent permitted, the warranties given to Lucent by its vendors
of such items. The Warranty Period for Products is 12 months and for Software is
three months. The Warranty Period commences on the earlier of (i) shipment of
Product or Licensed Material from Customer to End User Customer or (ii) 90 days
after Lucent's shipment of Product or Licensed Material to Reseller.

b. If, under normal and proper use, a defect or non-conformity appears in a
warranted Product or Software during the applicable Warranty Period and the End
User customer promptly notifies Customer in writing of such defect or
non-conformance, and follows Lucent's instructions regarding return of such
defective or non-conforming Product or Software, then Lucent will, at no charge
to End User customer, either (i) repair, replace or correct the same at its
manufacturing or repair facility or (ii) if Lucent determines that it is unable
or impractical to repair, replace or correct the Product or Software, provide a
refund or credit not to exceed the original purchase price or license fee.

c. No Product or Software will be accepted for repair or replacement without the
written authorization of and in accordance with instructions from Lucent.
Removal and reinstallation expenses as well as transportation expenses
associated with returning such Product or Software to Lucent shall be borne by
Customer. Lucent shall pay the costs of transportation of the repaired or
replaced Product or Software to any United States destination designated by
Customer. If Lucent determines that any returned Product or Software is not
defective, Customer shall pay Lucent's costs of handling, inspecting, testing
and transportation and, if applicable, travel and living expenses. In repairing
or replacing any Product, part of Product, or Software medium under this
warranty, Lucent may use either new, remanufactured, reconditioned, refurbished
or functionally equivalent Products, parts or Software media. Replaced Products
or parts shall become Lucent's property. If Lucent ascertains that a Product is
not readily returnable for repair, at its option, Lucent may elect to repair or
replace the Product at Customer's site. Customer, at its expense, shall make the
Products accessible for repair or replacement and shall restore the site after
Lucent has completed its repairs or replacement.

d. Lucent makes no warranty with respect to defective conditions or
non-conformities resulting from any of the following: Customer's modifications,
misuse, neglect, accident or abuse; improper wiring, repairing, splicing,
alteration, installation, storage or maintenance not performed by Lucent; use in
a manner not in accordance with Lucent's or its vendor's Specifications, or
operating instructions; failure of Customer to apply previously applicable
Lucent's modifications or corrections; or items not manufactured by Lucent or
purchased by Lucent pursuant to its procurement specifications. In addition,
Lucent makes no warranty with respect to Products which have had their serial
numbers or month and year of manufacture removed or altered; with respect to
expendable items, including, without limitation, fuses, light bulbs, motor
brushes and the like; or with respect to defects related to Customer's data base
errors. No warranty is made that Software will run uninterrupted or error free.

e. For Services purchased through Lucent, Lucent agrees to perform Services in a
workmanlike manner and in accordance with good usage and accepted practices in
the community in which Services are performed using material free from defects,
except where such material is provided by Customer or its End User customers. If
Services performed by Lucent prove not to have been so performed or if Lucent
fails to provide the Services or a portion thereof, and if Reseller or its End
User customers notifies Lucent to that effect within a ten (10) day period
commencing on the earlier of the date of completion of the Services or the date
that the Customer or End User customer knew or should have known of defects or
deficiencies, the Lucent, at its option, will either correct any defects and
deficiencies or render a full or pro-rated refund or credit based on the
original charge for Services.

f. THE FOREGOING WARRANTIES ARE EXCLUSIVE AND ARE GRANTED IN LIEU OF ALL OTHER
EXPRESS AND IMPLIED WARRANTIES (WHETHER WRITTEN, ORAL, STATUTORY OR
OTHERWISE), INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT.
CUSTOMER'S SOLE AND EXCLUSIVE REMEDY AND LUCENT's SOLE OBLIGATION HEREUNDER,
SHALL BE TO REPAIR, REPLACE, CREDIT OR REFUND AS SET FORTH ABOVE.
