                    INFORMATION TO BE INCLUDED IN THE REPORT



ITEM  2.


Effective April 26, 2000, U.S. Technologies Inc., a Delaware corporation (the
"Registrant"), through its wholly-owned subsidiary, E2Enet, Inc. ("E2Enet"),
completed its acquisition of 20,700,005 shares of common stock, with a par value
of $0.00001 per share, of Buyline.net, Incorporated, a Delaware corporation
("Buyline"), pursuant to the terms of a Stock Purchase Agreement, dated as of
April 26, 2000 (the "Purchase Agreement"), entered into by and among the
Registrant, Buyline, E2Enet, Northwood Capital Partners LLC ("Northwood
Capital"), Northwood Ventures LLC ("Northwood Ventures", and together with
Northwood Capital, "Northwood"), and Jonathan J. Ledecky ("Ledecky") (if he
acquires Buyline shares). As a result of this acquisition, and related
transactions described below, E2Enet owns 51.7% of the outstanding common stock
of Buyline, and Buyline became a controlled indirect subsidiary of the
Registrant.

Buyline is a developer of B2B e-commerce applications, and is developing a
proprietary Internet software program designed to be a universal platform for
entry-level B2B e-commerce, linking buyers and sellers. Buyline's application
for RFP/RFQ technology (Request for Proposal/Request for Quotation) will be
used in a full range of on-line advertising, on Internet-based directories, and
in commercial web sites.

Pursuant to the Purchase Agreement, E2Enet, purchased 20,700,005 shares of
Buyline's common stock, for an aggregate purchase price consisting of: (i)
$645,838.89 in cash; (ii) the cancellation by E2Enet and the Registrant of all
outstanding indebtedness owed by Buyline to E2Enet and the Registrant; and (iii)
Buyline's acknowledgment of having received, as a capital contribution by E2Enet
to Buyline, certain in-kind services. Also, pursuant to the Purchase Agreement,
Northwood acquired 3,450,000 shares of Buyline common stock at an aggregate
purchase price of $500,000 and Ledecky has expressed an intention to acquire,
but may not acquire, 1,725,000 shares of Buyline common stock at an aggregate
purchase price of $250,000. Separately, Michael Deale, President and CEO of
Buyline, and certain other Buyline employees acquired shares of Buyline common
stock.

Effective April 26, 2000, the Registrant issued 23,008 shares of common stock,
with a par value of $0.02 per share, to Lawrence Silverman ("Silverman")in
exchange for Silverman's sale of 634,699 shares of Buyline's common stock to
E2Enet. This exchange was consummated pursuant to the terms of that certain
Stock Exchange Agreement, dated as of April 26, 2000 ("Exchange Agreement"),
entered into by and among the Registrant, E2Enet, and Silverman.

In connection with the acquisition of the Buyline shares, E2Enet also pledged
all of its right, title, and interest in and to 4,485,000 shares of Buyline
common stock to Lightmedia Interactive Corporation ("Lightmedia"), a Delaware
corporation affiliated with Mr. Silverman, as security for a promissory note
Buyline made in favor of Lightmedia. The principal amount due under the note is
$650,000. The note bears interest at a rate equal to the prime rate as
published in the Wall Street Journal and requires monthly payments of $18,000.
The promissory note was made as consideration for the conditional (until the
note is fully paid) assignment of all Lightmedia's proprietary technology,
know-how and assets related to Buyline.

As a condition to entering the Purchase Agreement, E2Enet, along with the other
purchasers of Buyline shares, required Lawrence Silverman to execute a
noncompetition agreement to and for the benefit of Buyline. Under the terms of
the noncompetition agreement, Mr. Silverman agreed not to: 1) own or manage or
be connected with, in any manner, any entity engaged in developing or providing
systems and methods to improve the efficacy of on-line advertising, directories
and web sites and initiating electronic commerce on a one-to-one or one-to-many
basis; or 2) exercise control over or interfere with the management, operations
or conduct of Buyline unless requested to do so in writing. Buyline agreed to
pay Mr. Silverman $140,000, payable in twelve equal monthly installments of
$11,666.66, as consideration for his execution of the noncompetition agreement.

In connection with the Purchase Agreement, E2Enet entered into a Voting
Agreement, dated as of April 26, 2000 (the "Voting Agreement") with Northwood
Capital, Northwood Ventures and Ledecky (if he acquires Buyline shares). The
Voting Agreement provides that, subject to certain limitations, each Buyline
shareholder shall appoint E2Enet as its proxy and attorney-in-fact to vote any
voting shares of Buyline held by it for: a) the election of the nominees
designated by E2Enet to serve as directors on its board of directors; and, b) on
all other matters, to the extent necessary for E2Enet to have at least
twenty-five percent (25%) of the voting power on any matter submitted to a
shareholder vote or as E2Enet otherwise reasonably deems necessary for Buyline
to be considered a "controlled subsidiary" of E2Enet for purposes of the
Investment Company Act of 1940, as amended. Each party to the Voting Agreement
also agreed to vote all of its shares of Buyline common stock for the election
of either Lawrence Silverman or Ed Sager, as Mr. Silverman's designee, to the
board of directors until certain circumstances set forth in the Voting Agreement
are met.

By a side letter agreement, E2Enet agreed not exercise its right to vote any
Buyline shares held by Northwood or Ledecky (if he acquires Buyline shares)
following the fifth anniversary of the execution of the Voting Agreement. The
side letter agreement also provides that E2Enet, Northwood and Ledecky (if he
acquires Buyline shares) shall vote their respective Buyline shares to cause the
Buyline board of directors to be composed of seven members including: three
members designated by E2Enet; and one member

designated by each of Northwood, Edward Hauk (Buyline's non- executive
Chairman), Ed Sager (Mr. Silverman's designee per the Voting Agreement), and
Michael Deale (Buyline's President and CEO), so long as he is such. The side
letter agreement also contains certain rights of first refusal and carry-along
rights with respect to sales by E2Enet, Northwood and Ledecky (if he acquires
Buyline shares) of their Buyline
shares.

A portion of the net proceeds from the Registrant's recently completed private
placement of $5,184,000 of its voting Series C mandatorily convertible
preferred shares were used to fund the cash portion of the Registrant's
purchase price of its Buyline shares.

In connection with the acquisition of the Buyline shares, E2Enet also entered
into a registration rights agreement. Pursuant to the registration rights
agreement, E2Enet and the other parties thereto are entitled to have their
respective Buyline shares registered, at the expense of Buyline, under certain
circumstances.

The foregoing summaries do not comport to be complete.  The relevant agreements
are exhibits hereto and incorporated herein by reference.  See Item 7(c).

              (a) Schedule 6.12(a) lists or describes: (i) all unexpired
written or oral contracts, leases, agreements, arrangements, commitments,
instruments or understandings (collectively, "Contracts") that restrict the
Company from engaging in any business activity; (ii) all barter Contracts with
any Person; (iii) all Contracts of every nature to which the Company is a party
or to which it or any of its assets or properties are bound if such Contract
obligates the Company to pay more than $25,000 in remaining payment
obligations; and (iv) the license of any patent, copyright, trademark, trade
secret, or other proprietary right to or from the Company. Each Contract listed
on Schedule 6.12(a) represents a valid, binding and enforceable agreement of
the Company, and, to the knowledge of the Company, the other party or parties
thereto, except as enforcement thereof may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to or affecting
creditors' rights generally and by general principles of equity.

              (b) True, complete and correct copies of all written Contracts
listed in Schedule 6.12(a) have been made available to the Investors and true,
complete and correct descriptions of all oral Contracts have been provided
therein. Each such Contract is enforceable in accordance with its terms (except
as may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium or similar laws relating to or affecting creditors' rights generally
and by general principles of equity) and is in full force and effect. The
Company is not, nor to its knowledge, is any other party to any of such
Contracts (with or without the lapse of time or the giving of notice, or both),
in material violation thereof or in material default thereunder.

         6.13 Absence of Undisclosed Liabilities. Except for the Liabilities
set forth on the Financial Statements the Company does not have any Liabilities
of any kind whatsoever, either accrued,


                                       14
<PAGE>   19


absolute, contingent, determined or determinable or otherwise, or any existing
condition, situation or set of circumstances that could reasonably be expected
to result in such a Liability (including documentary or standby letters of
credit, bid or performance bonds or customer or third party guarantees). To the
Company's knowledge, there are no asserted claims for indemnification by any
Person against the Company under any Law or agreement or pursuant to the
Organizational Documents of the Company, and the Company has no knowledge of
any facts or circumstances that could reasonably be expected to give rise to
the assertion of such a claim against the Company thereunder.

         6.14 Absence of Certain Changes or Events. Since June 30, 1999, the
Company has conducted its business in the ordinary and regular course
consistent with past practices, and there has not been:

              (a) any material adverse effect;

              (b) any material damage, destruction or casualty loss to any
material asset or property of the Company that is not covered by insurance that

compensation or other similar agreement or any arrangement with any of its
officers or employees; any increase in the rate or terms of the compensation
payable or to become payable to employees of the Company, except increases
occurring in accordance with customary practices or in accordance with
employment agreements, or any modification in employee benefits, or any
borrowing of money from the Company by any employee of the Company (other than
routine travel and similar advances);

              (d) any sale, assignment, lease, transfer or other disposition,
or the execution of any agreement for the sale, assignment, lease, transfer or
other disposition, of any material assets of the Company;

              (e) any change by the Company in accounting or bookkeeping
methods, principles or practices, except as required by GAAP;

              (f) any borrowing of money, including any increase or extension
of purchase money credit of the Company or any increase in the Liabilities of
the Company from those reflected in the Financial Statements;

              (g) any transaction with any officer, director or shareholder
(including any of their respective family members) of the Company or any of
their respective Affiliates, other than payments of salary and employee
benefits in the ordinary course;


                                       15
<PAGE>   20


              (h) any declaration or payment of any dividend or other
distribution on or with respect to, or any redemption or purchase or other
acquisition of, the capital stock of the Company; or

              (i) any change in any material Tax election or any other action
with respect to Taxes that is inconsistent with past practices.

         6.15 Certain Fees. The Company has not entered into, nor will it enter
into, during the term of this Agreement, any agreement, arrangement or
understanding with any Person that will result in the obligation of the
Investors to pay any finder's fee, brokerage commission or similar payment in
connection with the transactions contemplated hereby.

         6.16 Books and Records. The minute books and other similar records of
the Company contain a true, complete and correct record, in all respects, of
all actions taken at all meetings and by all written consents in lieu of
meetings of the stockholders and the boards of directors of the Company. The
stock book and the share certificate ledgers and other similar records of the
Company as made available to the Investors (or any of their representatives)
accurately reflect all record transfers and any rights or Contracts related to
or involving any shares of capital stock of the Company. The Company does not
have any of its Books and Records recorded, stored, maintained, operated or
otherwise wholly or partly dependent upon or held by any means (including any
electronic, mechanical or photographic process, whether computerized or not)
which (including all means of access thereto and therefrom) are not under the
exclusive ownership and direct control of the Company.

         6.17 Investments in Other Persons. Except as disclosed in the
Contracts listed on Schedule 6.12(a), the Company has not made any investment
in, or loan or advance (other than trade credit advanced in the ordinary course
of business and consistent with past practices) to, any Person which is
outstanding on the date of this Agreement, nor is the Company obligated or
committed to make any such loan or advance. Each such investment constitutes a
duly authorized and valid investment by the Company pursuant to any written or
oral Contract.

        6.18 Related-Party Transactions and Certain Actions. Except as set
forth on Schedule 6.18, no employee, officer, consultant, stockholder or
director of the Company or member of his or her immediate family is indebted to
the Company, nor is the Company indebted (or committed to make loans or
guarantee credit) to any of them, other than (i) for payment of salary for
services rendered; (ii) reimbursement for reasonable expenses incurred on
behalf of the Company; and (iii) for other standard employee benefits made
generally available to all employees. Other than as set forth on Schedule 6.18,
to the knowledge of the Company, none of such persons has any direct or
indirect ownership interest in any firm or corporation with which the Company
is affiliated or with which the Company has a business relationship, or any
firm or corporation that competes with the Company, except that employees,
stockholders, officers, or directors of the Company may own stock in publicly
traded companies that may compete with the Company. Other than as set forth on
Schedule 6.18, no officer, director, consultant or stockholder or any member of
their


                                       16
<PAGE>   21


immediate families is, directly or indirectly, interested in any material
contract with the Company (other than such contracts as relate to any such
person's related ownership of capital stock or other securities of the Company
and employment agreements entered into in the ordinary course). The Company has
not (A) declared or paid any dividends or authorized or made any distributions
upon or with respect to any class or series of its capital stock, (B) incurred
any indebtedness for money borrowed or any other liabilities individually or in
excess of $10,000, (C) made any loans or advances to any person, other than
ordinary advances for travel expenses, or (D) sold, exchanged or otherwise
disposed of any of its assets or rights having a value in excess of $10,000,
other than the sale of its inventory in the ordinary course of business.

        6.19 Patents and Trademarks. The Company owns or possesses, or will
acquire prior to use, sufficient legal rights to all patents, trademarks,
service marks, trade names, copyrights, trade secrets, licenses, information
and proprietary rights and processes necessary for its business as now
conducted (including without limitation its corporate names) and as proposed to
be conducted to the knowledge of the Company without any conflict with, or
infringement of the rights of, others. Except as set forth on Schedule 6.19,
the Company has no patents or pending patent applications. Except for
agreements with its own employees or consultants, substantially in the form
referenced in Section 6.20 below, and standard end-user license agreements,
there are no outstanding options, licenses, or agreements of any kind relating
to the foregoing, nor is the Company bound by or a party to any options,
licenses, or agreements of any kind with respect to the patents, trademarks,
service marks, trade names, copyrights, trade secrets, licenses, information
and proprietary rights and processes of any other person or entity. To the
knowledge of the Company, the Company has not violated or, by conducting its
business as proposed, would not violate, any of the patents, trademarks,
service marks, trade names, copyrights, trade secrets or any other proprietary
rights or processes of any person or entity. To the knowledge of the Company,
none of its employees is obligated under any contract (including licenses,
covenants, or commitments of any nature) or any other agreement, or subject to
any judgment, decree or order of any court or administrative agency, that would
interfere with the use of such employee's best efforts to promote the interests
of the Company or that would conflict with the Company's business as proposed
to be conducted. To the Company's knowledge, neither the execution nor delivery
of this Agreement, nor the carrying on of the Company's business by the
employees of the Company, nor the conduct of the Company's business as
currently conducted, will conflict with or result in a breach of the terms,
conditions or provisions of, or constitute a default under, any contract,
covenant, or instrument under which any of such employees is now obligated. To
the knowledge of the Company, it is not, nor will it be, necessary for the
Company to use any inventions of any of its employees (or persons it currently
intends to hire) made prior to their employment by the Company.

        6.20 Proprietary Information and Inventions Agreements. Other than as
set forth on Schedule 6.20, each current employee, officer and consultant of
the Company has executed a nondisclosure agreement substantially in the form or
forms which has or have been delivered to the Investors.

         6.21 Disclosure. No representation or warranty made by the Company in
this Agreement or any Schedule hereto, or any certificate furnished or to be
furnished by it in connection with this Agreement, contains or will contain an
untrue statement of material fact, or omits or will omit to state a material
fact necessary to make the statements contained herein or therein, in light of
the circumstances in which they were made, not misleading.

                                  ARTICLE VII
                                INDEMNIFICATION

         7.1 Indemnification. The Company shall indemnify the Investors against
and agrees to hold the Investors harmless from any and all claims, damages,
losses, liabilities and expenses (including, without limitation, reasonable
expenses of investigation and reasonable attorneys' fees and expenses in
connection with any action, suit or proceeding) (collectively, "Damages")
actually incurred or suffered by the Investors on or after the date hereof
arising out of any misrepresentation, inaccuracy or breach of any
representation, warranty or covenant by the Company contained in this Agreement
(or in any certificate, document, list, schedule, Investment Document, or
exhibit expressly required by the terms of this Agreement to be delivered to
the Investors by the Company hereunder). The maximum aggregate liability of the
Company under this Article VII shall be the aggregate amount of the
consideration paid or contributed by the Investors for the Company Shares. If
the Investors shall seek indemnification pursuant to this Article VII, the
Investors shall give prompt notice to the Company of the assertion of any
claim, or the commencement of any action, suit or proceeding by a third party,
in each case in respect of which indemnity may be sought hereunder, but no
failure to give such notice shall relieve the Company of any liability
hereunder. The Company may, at its expense, participate in or assume the
defense of any such action, suit or proceeding involving a third party with
counsel reasonably acceptable to the Investors, and after notice from the
Company of its election to assume the defense thereof, the Company shall not be
liable to the Investors for any legal fees or other expenses subsequently
incurred by the latter in connection with the defense thereof. The Investors
will have the right to employ their counsel in any such action, but the fees
and expenses of such counsel will be at the expense of such Investors unless
(1) the employment of counsel by the Investors has been authorized in writing
by the Company, (2) the Investors have reasonably concluded that there may be
legal defenses available to them that are different from or in addition to
those available to the Company (in which case the Company will not have the
right to direct the defense of such action on behalf of the Investors) or (3)
the Company has not in fact employed counsel to assume the defense of such
action within a reasonable time after receiving notice of the commencement of
the action, in each of which cases the reasonable fees and expenses of only one
counsel will be at the expense of the Company, and the Company shall reimburse
or pay such fees and expenses as they are incurred. Whether or not the Company
chooses to defend or prosecute any claim involving a third party, all the
parties hereto shall cooperate in the defense or prosecution thereof and shall
furnish such records, information and testimony, and attend such conferences,
discovery proceedings, hearings, trials and appeals, as may be reasonably
requested in connection therewith. The Company shall not be liable under this
Article VII for any settlement effected without its consent of any claim,
litigation or proceeding by a third party in respect of which indemnity may be
sought hereunder (which consent shall not be unreasonably withheld),


                                       18
<PAGE>   23


unless the Company refuses to acknowledge liability for indemnification under
this Article VII and/or declines to defend any of the Investors in such claim,
litigation or proceeding.

                                  ARTICLE VIII
                                 MISCELLANEOUS

         8.1 Severability. If any term, provision, covenant or restriction of
this Agreement is held to be invalid, void or unenforceable, such provision
shall be amended by the Parties only to the extent necessary to be enforceable
consistent with the Parties' intent, and the remainder of the terms,
provisions, covenants and restrictions of this Agreement shall remain in full
force and effect, unless such action would substantially impair the benefits to
any Party of the remaining provisions of this Agreement.

         8.2 Survival of Representations and Warranties. All representations
and warranties contained herein or made in writing by any party in connection
herewith shall survive the execution and delivery of this Agreement and the
consummation of the transactions contemplated by this Agreement until the
second anniversary of the date hereof, regardless of any investigation made by
any Investor or on its behalf, provided, however, that the representations
contained in the last sentence of Section 6.2 and the third sentence of Section
6.3 shall survive indefinitely.

         8.3 Entire Agreement; Amendments. This Agreement (including the
schedules and exhibits hereto) and the other documents and instruments referred
to herein contain the entire understanding of the Parties with respect to the
matters covered hereby and supersede all other prior agreements (including the
Agreement in Principle for Restructuring in connection with Acquisition of
E2Enet, dated as of February 28, 2000, between USXX and Buyline) and
understandings, both written and oral, among the Parties, with respect to the
subject matter hereof. This Agreement may be amended only by an instrument in
writing executed by the Parties.

         8.4 Notices. Any notices or communications required or permitted
hereunder shall be in writing and addressed as follows:

         8.10 Governing Law. This Agreement shall be governed by and construed
and enforced in accordance with the laws of the State of Delaware, without
regard to the conflicts of laws principles thereof.

         8.11    Dispute Resolution.

              (a) All disputes, controversies, and claims directly or
indirectly arising out of or in relation to this Agreement or the validity,
interpretation, construction, performance, breach or enforceability of this
Agreement shall be finally, exclusively and conclusively settled by binding
arbitration, as provided in this Section, by a single arbitrator under the
Commercial Arbitration Rules, as then amended and in effect, of the American
Arbitration Association (the "AAA"). The arbitration proceedings shall be
conducted and any arbitral award shall be made in Washington, DC.

              (b) The Parties agree: (i) to be bound by any arbitral award or
Order resulting from any arbitration conducted thereunder and that any such
award or Order shall be a reasoned award, shall be in writing, shall specify
the factual and legal basis for the award, and shall be final and binding; (ii)
not to commence, procure, participate in, or otherwise be involved as a party
in any claim, Action or Proceeding that might result in any Order concerning a
dispute (except for initiating Actions or Proceedings to obtain a judgment
recognizing or enforcing an arbitral award or Order and except for
applications, claims, Actions or Proceedings by the Parties, seeking interim
interlocutory or other provisional relief in any court having jurisdiction, but
only on the ground that the award to which the applicant may be entitled may be
rendered ineffectual without such provisional relief); and (iii) that judgment
on any arbitral award or Order resulting from an arbitration conducted under
this Section may be entered in any court of competent jurisdiction having
jurisdiction thereof or having jurisdiction over any Party or any of their
assets.

              (c) Each of the Parties hereby irrevocably waives and excludes
all rights of appeal, challenge, or recourse to any court from any arbitral
award or Order resulting from any arbitration conducted under this Section
(except for initiating Actions or Proceedings to obtain a judgment recognizing
or enforcing an arbitral award or Order and except for Actions or Proceedings
seeking interim, interlocutory or other provisional relief in any court having
jurisdiction, but only on the ground that the award to which the applicant may
be entitled may be rendered ineffectual without such provisional relief). Each
of the Parties to this Agreement hereby consents to the non-exclusive
jurisdiction of any court of competent jurisdiction in Washington, DC for all
Actions or Proceedings to obtain a judgment recognizing or enforcing an
arbitral award or Order and waives any defense or opposition to such
jurisdiction.

              (d) The arbitrator, in its discretion, may consolidate two or
more arbitrations or claims between any of the Parties arising pursuant to this
Agreement or any other agreement among the parties into one arbitration, or
terminate any such consolidation and/or establish other arbitration proceedings
for different claims that may arise in any one arbitration. Notwithstanding the
foregoing, the arbitrator shall consolidate arbitrations and/or claims if he
determines that it would be more efficient to consolidate such arbitrations
and/or claims than to continue them


                                       22
<PAGE>   27


separately and (i) there are matters of fact or law that are common to the
arbitrations and/or claims to be consolidated, (ii) there are related payment
and performance obligations considered in the arbitrations and/or claims to be
consolidated or (iii) there is a danger of inconsistent awards.

              (e) Each Party shall bear its own expenses in connection with the
arbitration provided in this Section, provided that the fees of the arbitrator
shall be divided equally between the Parties.

         8.12 Drafting. Each Party acknowledges that its legal counsel
participated in the preparation of this Agreement. The Parties therefore
stipulate that the rule of construction that ambiguities are to be resolved
against the drafting party shall not be employed in the interpretation of this
Agreement to favor any Party against any other.

         8.13 WAIVER OF JURY TRIAL. EACH PARTY HERETO WAIVES, TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, THE RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY.

         8.14 Expenses. Except as otherwise expressly provided herein, each of
the Parties hereto shall bear and pay all costs and expenses incurred by it or
on its behalf in connection with the transactions contemplated hereunder,
including fees and expenses of its own financial consultants, investment
bankers, accountants and counsel.

         8.15 Further Assurances. From and after the date of this Agreement,
each Party shall execute and deliver such instruments, documents and other
writings as may be reasonably necessary or desirable to confirm and carry out
and to effectuate fully the intent and purposes of this Agreement, including,
without limitation, any of the foregoing that may be necessary in connection
with the transactions contemplated in Section 2.1(e).

         8.16 Disclosure to Other Persons. No Party hereto shall issue, make or
cause the publication of any press release or other announcement with respect
to this Agreement or the transactions contemplated hereby, or otherwise make
any disclosures relating thereto, without the consent of the other Parties,
such consent not to be unreasonably withheld or delayed; provided, however,
that such consent shall not be required where such release or announcement is
required by applicable law or the rules or regulations of a securities
exchange, in which event the Party so required to issue such release or
announcement shall endeavor, wherever possible, to furnish an advance copy of
the proposed release to the other Parties.

Agreement shall be finally, exclusively and conclusively settled by binding

conducted and any arbitral award shall be made in Washington, DC.

                                       10

<PAGE>   14

                  (b)      The Parties agree: (i) to be bound by any arbitral
award or Order resulting from any arbitration conducted thereunder and that any
such award or Order shall be a reasoned award, shall be in writing, shall
specify the factual and legal basis for the award, and shall be final and
binding; (ii) not to commence, procure, participate in, or otherwise be involved
as a party in any claim, Action or Proceeding that might result in any Order
concerning a dispute (except for initiating Actions or Proceedings to obtain a
judgment recognizing or enforcing an arbitral award or Order and except for
applications, claims, Actions or Proceedings by the Parties, seeking interim
interlocutory or other provisional relief in any court having jurisdiction, but
only on the ground that the award to which the applicant may be entitled may be
rendered ineffectual without such provisional relief); and (iii) that judgment
on any arbitral award or Order resulting from an arbitration conducted under
this Section may be entered in any court of competent jurisdiction having
jurisdiction thereof or having jurisdiction over any Party or any of their
assets.

                  (c)      Each of the Parties hereby irrevocably waives and
excludes all rights of appeal, challenge, or recourse to any court from any
arbitral award or Order resulting from any arbitration conducted under this
Section (except for initiating Actions or Proceedings to obtain a judgment
recognizing or enforcing an arbitral award or Order and except for Actions or
Proceedings seeking interim, interlocutory or other provisional relief in any
court having jurisdiction, but only on the ground that the award to which the
applicant may be entitled may be rendered ineffectual without such provisional
relief). Each of the Parties to this Agreement hereby consents to the
non-exclusive jurisdiction of any court of competent jurisdiction in Washington,
DC for all Actions or Proceedings to obtain a judgment recognizing or enforcing
an arbitral award or Order and waives any defense or opposition to such
jurisdiction.

                  (d)      The arbitrator, in its discretion, may consolidate
two or more arbitrations or claims between any of the Parties arising pursuant
to this Agreement or any other agreement among the parties into one arbitration,
or terminate any such consolidation and/or establish other arbitration
proceedings for different claims that may arise in any one arbitration.
Notwithstanding the foregoing, the arbitrator shall consolidate arbitrations
and/or claims if he determines that it would be more efficient to consolidate
such arbitrations and/or claims than to continue them separately and (i) there
are matters of fact or law that are common to the arbitrations and/or claims to
be consolidated, (ii) there are related payment and performance obligations
considered in the arbitrations and/or claims to be consolidated or (iii) there
is a danger of inconsistent awards.

                  (e)      Each Party shall bear its own expenses in connection
with the arbitration provided in this Section, provided that the fees of the
arbitrator shall be divided equally between the Parties.

         7.12     Drafting. Each Party acknowledges that its legal counsel
participated in the preparation of this Agreement. The Parties therefore
stipulate that the rule of construction that ambiguities are to be resolved
against the drafting party shall not be employed in the interpretation of this
Agreement to favor any Party against any other.

or on its behalf in connection with the transactions contemplated hereunder,
including fees and expenses of its own financial consultants, investment
bankers, accountants and counsel.

         7.15     Further Assurances. From and after the date of this Agreement,
each Party shall execute and deliver such instruments, documents and other
writings as may be reasonably necessary or desirable to confirm and carry out
and to effectuate fully the intent and purposes of this Agreement.

         7.16     Disclosure to Other Persons. No Party hereto shall issue, make
or cause the publication of any press release or other announcement with respect
to this Agreement or the transactions contemplated hereby, or otherwise make any
disclosures relating thereto, without the consent of the other Parties, such
consent not to be unreasonably withheld or delayed; provided, however, that such
consent shall not be required where such release or announcement is required by
applicable law or the rules or regulations of a securities exchange, in which
event the Party so required to issue such release or announcement shall
endeavor, wherever possible, to furnish an advance copy of the proposed release
to the other Parties.

                             STOCK PLEDGE AGREEMENT

         THIS STOCK PLEDGE AGREEMENT ("Pledge Agreement") is entered into as of
April 26, 2000, between LIGHTMEDIA INTERACTIVE CORPORATION, a Delaware
corporation ("Pledgee"), and E2ENET, INC., a Delaware corporation ("Pledgor").

         1. Pledgee has entered into the Bill of Sale and Assignment Agreement
of even date herewith (the "Assignment Agreement") with Buyline.net,
Incorporated ("Buyline"), pursuant to which Pledgee assigned to Buyline all of
its proprietary technology and know-how and related assets, and as consideration
for such assignment, Buyline has agreed to pay Pledgee $650,000, the payment of
which is evidenced by that certain Promissory Note executed on the date hereof
by Buyline in favor of Pledgee (the "Note"). As collateral security for the
Note, Pledgor hereby pledges to Pledgee all of its right, title and interest in
and to all shares of common stock of Buyline listed in Schedule A hereto, which
number of Shares pledged shall be reduced from time to time in proportion to the
reduction in the amount of principal under the Note from time to time
outstanding compared to the amount of principal outstanding on the date hereof
(Pledgor's "Shares" or the "Collateral"). The terms of the Assignment Agreement
and the Note are specifically incorporated herein.

         2. The Pledgor represents and warrants: (i) that it is the owner of the
Shares; (ii) that the Shares are free and clear of all pledges, charges, liens
or other encumbrances whatsoever, except the pledge created hereby, and (iii)
that this pledge does not violate any other agreement or undertaking of Pledgor.

         3. Pledgee's interest in the Collateral shall be as security for the
payment of all principal and interest due on the Note.

         4. The stock certificate representing the Shares has been duly endorsed
in blank and has been delivered to Pledgee. In executing this Stock Pledge
Agreement, Pledgee acknowledges receipt of the Shares.

         5. Following the delivery of the Collateral to Pledgee as provided in
Section 4 hereof, unless and until there shall be a breach of any of the
obligations specified in Section 3:

            a. The Pledgor shall be entitled to exercise all voting and
consensual powers pertaining to the Shares for all purposes not inconsistent
with the terms of this Stock Pledge Agreement;

            b. The Pledgor shall be entitled to receive directly and retain all
dividends or interest on the Shares unless otherwise restricted; and

            c. In order to permit Pledgor to exercise such voting powers and to
receive such dividends or interest, Pledgee shall from time to time, upon
the written request of Pledgor, execute and deliver to Pledgor appropriate
proxy, dividend and reinvestment orders.

         6. Following the delivery of the Collateral to Pledgee as provided in
Section 4 hereof, if any breach by the Pledgor of its obligations specified in
Section 3 shall have occurred and be continuing:

            a. Pledgee may, after twenty (20) days written notice to Pledgor,
cause any or all of the Collateral to be transferred into Pledgee's name as
record owner hereunder;

            b. All dividends and other distributions thereafter made upon or in
respect to the Collateral, or any part thereof, shall be paid directly to and
shall be retained by Pledgee; or

            c. Pledgee may liquidate or sell all or a part of the Collateral at
a public or private sale upon terms and conditions satisfactory to it in its
discretion, subject as hereinafter provided to Title 28, Section 9-504 of the
Commercial Code of the State of Delaware. Pledgee shall then deduct from the
proceeds of such sale all amounts then due and owing to it under the Note and
the Assignment Agreement and shall remit any remaining balance of the proceeds
to Pledgor. Anything contained herein to the contrary notwithstanding, Pledgor
and Pledgee agree that the Collateral shall be disposed of in accordance with
Title 28, Section 9-504 of the Commercial Code of the State of Delaware.

         7. If the principal of and interest on the Note are paid in accordance
with the terms thereof, this Stock Pledge Agreement shall thereupon terminate,
and Pledgee shall deliver to Pledgor the Collateral and any dividends held
thereon by Pledgee.

         8. This Pledge Agreement shall in all respects be construed in
accordance with and governed by the laws of the State of Delaware and no defense
given or allowed by the laws of any other country or state shall be interposed
in any action hereon unless such defense is also given or allowed by the laws of
the State of Delaware.

                                VOTING AGREEMENT


         This Voting Agreement ("Agreement"), dated as of April 26, 2000, is
made by and among E2Enet, Inc., a Delaware corporation ("E2E"), Northwood
Capital Partners LLC, a New York limited liability company ("Northwood

("Northwood Ventures" and, together with Northwood Capital, "Northwood"),
Jonathan J. Ledecky, individually ("Ledecky"), and each of the other
shareholders of Buyline.net, Incorporated, a Delaware corporation ("Buyline"),
listed on the signature pages hereto (each, a "Shareholder" and, collectively,
the "Shareholders").

                             PRELIMINARY STATEMENTS

         Concurrently with the execution of this Agreement, E2E, Northwood,
Ledecky (collectively, the "Investors") and Buyline entered into a Stock
Purchase Agreement (the "Purchase Agreement"), pursuant to which the Investors
acquired shares of common stock, par value $0.00001 per share ("Common Stock"),
of Buyline.

         The Shareholders, Ledecky and Northwood own the number of shares of
Common Stock set forth opposite their respective names on Exhibit A hereto (such
shares set forth on Exhibit A being referred to as the "Shares"), which Shares
represent 86.9% of the issued and outstanding Common Stock. Also set forth on
Exhibit A for the Shareholders, Ledecky and Northwood is a description of all
present options, warrants and other rights to acquire shares of Common Stock.

         To induce the Investors to enter into the Purchase Agreement, the
Shareholders have agreed, upon the terms and subject to the conditions set forth
herein, to appoint E2E as their true and lawful proxy, to vote the Shares owned
by them in favor of the election of any person nominated by E2E to be on the
Board of Directors (the "Board") of Buyline (except as set forth in Section 3
below), and to vote on all other matters to the extent necessary for E2E to have
at least twenty-five percent (25%) of the voting power on any matter submitted
to a shareholder vote.

         To further induce E2E to enter into the Purchase Agreement, Ledecky and
Northwood have agreed, upon the terms and subject to the conditions set forth
herein, to appoint E2E as their true and lawful proxy, to vote the Shares owned
by them in favor of the election of any person nominated by E2E to be on the
Board of Buyline (except as set forth in Section 3 below), and to vote on all
other matters to the extent necessary for E2E to have at least twenty-five
percent (25%) of the voting power on any matter submitted to a shareholder vote.


<PAGE>   2

         For good and valuable consideration, the receipt, sufficiency, and
adequacy of which are hereby acknowledged, the parties to this Agreement agree
as follows:

         1. Representations and Warranties of the Shareholders, Ledecky
and Northwood. Each Shareholder and each of Ledecky and Northwood, as to itself
and to its Shares only, represents and warrants that:

            (a) It owns, or is otherwise able to direct the voting of, the
Shares set forth next to its name on Exhibit A hereto, free and clear of any
restrictions on voting, and has the right to vote the same free of any such
encumbrance (other than any general fiduciary obligation imposed by law).

            (b) The execution, delivery and performance of this Agreement by it
does not (i) conflict with or violate any trust or other agreement or instrument
to which or by which it is a party or is bound, (ii) conflict with or violate
any law, rule, regulation, order, judgment or decree applicable to it or by
which its Shares are bound or affected, or (iii) result in any breach of or
constitute a default (or an event that with notice or lapse of time or both
would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation of, or result in the creation of a lien
or encumbrance on any of its Shares pursuant to, any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation to which it is a party or by which it or its Shares is
or are bound or affected.

            (c) The execution, delivery and performance of this Agreement by it
does not and will not require any consent, approval, authorization or permit of
any foreign, federal, state, or local regulatory body.

         2. Agreements with Respect to the Shares.

            (a) Voting. Subject to subsection (b) of this Section 2, each
Shareholder and each of Ledecky and Northwood agrees during the term of this
Agreement to appoint E2E as its true and lawful proxy and attorney-in-fact with
full power of substitution, to vote those Shares owned and eligible to vote and
any other shares of Common Stock of which at the time of such vote it is able to
direct the voting (and any other voting securities of Buyline issued or
exchanged with respect to all such shares upon any reclassification,
recapitalization, reorganization, stock split, stock dividend or any other
change in Buyline's capital structure) for:

                i)   the election (or removal) of the nominees designated
                     by E2E to serve as directors on the Board and, in the event
                     of a vacancy on the Board created by the death, resignation
                     or removal of such director, to vote for the election of
                     nominees designated by E2E; and,


                                       -2-

<PAGE>   3



                ii)  on all other matters, to the extent necessary for E2E to
                     have at least twenty-five percent (25%) of the voting power
                     on any matter submitted to a shareholder vote or as E2E
                     otherwise reasonably deems necessary for Buyline to be
                     considered a "controlled subsidiary" of E2E for purposes
                     of the Investment Company Act of 1940, as amended, and as
                     in effect from time to time.

            (b) Limitations. The proxy granted in subsection (a) above may be
exercised by E2E upon five (5) days' prior written notice to the Shareholders,
Ledecky and Northwood of its intent to exercise such voting rights. The
Shareholders' proxy granted in subsection (a) above may be exercised only if
Buyline is current in all payments due under that certain Noncompetition
Agreement of even date hereof between Lawrence Silverman and Buyline and under
that certain Promissory Note of even date hereof by Buyline in favor of
LightMedia Interactive Corporation ("LightMedia"). E2E may exercise the
Shareholder's proxy as it relates to Section 2(a)(ii) above only to the extent
necessary after E2E exercises its proxy to vote shares held by Northwood and
Ledecky.

         3. Board of Buyline. Notwithstanding the foregoing, by execution
hereof, each Shareholder and Investor agrees to vote all of its shares of Common
Stock for the election of Lawrence Silverman to the Board (or instead, upon the
request of E2E, Ed Sager), until the earlier of (x) the date that the
Shareholders, in one or more transactions, whether or not related, have sold or
transferred more than 50% of the shares of Common Stock collectively owned by
them as of the date hereof, (y) the date that the shares of Common Stock held by
the Shareholders collectively represent less than 20% of the aggregate number of
shares of Buyline issued and outstanding or (z) the termination of this
Agreement.

         4. No Voting Trusts. Each Shareholder and each of Ledecky and Northwood
hereby revokes any and all proxies and voting instructions with respect to the
Shares previously given by it or him, and agrees that it or he will not, nor
will he or it permit any entity under its or his control to, deposit any of its
or his Shares in a voting trust or subject any of its or his Shares to any
arrangement with respect to the voting of such Shares inconsistent with this
Agreement.

         5. Limitation on Sales. During the term of this Agreement, each
Shareholder and each of Ledecky and Northwood agrees not to sell, assign,
transfer, lend, tender, pledge, hypothecate, exchange, encumber or otherwise
dispose of or impair its or his Shares unless, in connection therewith, it or he
retains voting rights with respect to its or his Shares or the person or entity
which obtains such voting rights becomes a party to, or agrees to be subject to
the terms of, this Agreement.

         6. Specific Performance. Each Shareholder and each of Ledecky and
Northwood acknowledges that it will be impossible to measure in money the damage
to E2E if it or he


                                       -3-

<PAGE>   4

fails to comply with the obligations imposed by this Agreement, and that, in the
event of any such failure, E2E will not have an adequate remedy at law or in
damages. Accordingly, each Shareholder and each of Ledecky and Northwood agrees
that injunctive relief or any other equitable remedy, in addition to any
remedies at law or damages, is the appropriate remedy for any such failure and
will not oppose the granting of any such remedy on the basis that E2E has an
adequate remedy at law. Each Shareholder and each of Ledecky and Northwood
agrees not to seek, and agrees to waive any requirement for, the securing or
posting of a bond in connection with E2E's seeking or obtaining such equitable
relief.

         7. Term of Agreement; Termination. The term of this Agreement shall
commence on the date hereof and shall terminate by the mutual, written agreement
of the parties or on the ten (10) year anniversary of the date hereof. Upon such
termination, no party shall have any further obligations or liabilities
hereunder; provided, however, that, such termination shall not relieve any party
from liability for any uncured breach of this Agreement occurring prior to such
termination.

         8. Miscellaneous.

            (a) Entire Agreement. This Agreement constitutes the entire
agreement among the parties with respect to the subject matter of this Agreement
and supersedes all prior written and oral and all contemporaneous oral
agreements and understandings with respect to the subject matter of this
Agreement.

            (b) Notices. Any notice, request, instruction or other document to
be given hereunder by any party to the others shall be in writing and shall be
deemed to have been duly given on the next business day after the same is sent,

permitted by law, further waives any right to have a jury participate in any
suit filed by another party hereto with respect to any dispute relating hereto.

            (e) Rules of Construction. The descriptive headings in this
Agreement are inserted for convenience of reference only and are not intended to
be part of or to affect the meaning or interpretation of this Agreement. Words
used in this Agreement, regardless of the gender and number specifically used,
shall be deemed and construed to include any other gender, masculine or
feminine, or neuter, and any other number, singular or plural, as the context
requires. As used in this Agreement, the word "including" is not limiting, and
the word "or" is not exclusive.

            (f) Parties in Interest. This Agreement shall be binding upon and
inure solely to the benefit of the parties to this Agreement and their legal
successors-in-interest, transferees or assignees and nothing in this Agreement,
express or implied, is intended to confer upon any other person any rights or
remedies of any nature whatsoever under or by reason of this Agreement.

            (g) Counterparts. This Agreement may be executed in one or more
counterparts, and each of such counterparts shall for all purposes be deemed to
be an original, but all such counterparts together shall constitute but one
instrument.

            (h) Assignment. No party hereto shall assign its rights and
obligations under this Agreement or any part thereof, nor shall any party assign
or delegate any of its rights or duties hereunder without the prior written

be void; provided, that the rights and obligations of E2E hereunder may be
assigned to and assumed by any affiliate of E2E, including, without limitation,
U.S. Technologies Inc. Except as otherwise provided herein, this Agreement shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and permitted assigns.

the other parties to this Agreement, (b) waive any inaccuracies in the
representations and warranties of any other party contained herein or in any
document, certificate, or writing delivered pursuant to this Agreement by any
other party, or (c) waive compliance by any other party with any of the
agreements or conditions contained herein or any breach thereof. Any agreement
on the part of any party to any such extension or waiver shall be valid only if
set forth in an instrument in writing signed on behalf of such party.

            (k) Legal Fees; Costs. If any party to this Agreement institutes any
action or proceeding, whether before a court or arbitrator, to enforce any
provision of this Agreement, the prevailing party therein shall be entitled to
receive from the losing party reasonable attorneys' fees and costs incurred in
such action or proceeding, whether or not such action or proceeding is
prosecuted to judgment.

            (l) Severability. The provisions of this Agreement are severable
and, if any provision of this Agreement is determined to be invalid or
unenforceable by any court of competent jurisdiction, such provision (in any
other jurisdiction) and the other provisions hereof (in any jurisdiction) shall
not be rendered otherwise invalid or unenforceable and such provision shall be
deemed to be modified to the extent necessary to render it legal, valid and
enforceable, and if no such modification shall render it legal, valid and
enforceable, then this Agreement shall be construed as if not containing the
provision held to be invalid, and the rights and obligations of the parties
shall be construed and enforced accordingly.

            (m) Fiduciary Duty as Director. Each of the parties hereto
acknowledges and agrees that none of the provisions herein set forth shall be
deemed to restrict or limit any fiduciary duty that any of the undersigned may
have as a member of the Board or as an executive officer of Buyline; provided
that, no such duty shall excuse the undersigned from performing any obligations
as herein provided and otherwise complying with the terms and conditions of this
Agreement.

         Re:      Voting Agreement re Buyline.net, Incorporated

Gentlemen:

         Reference is made to that certain Voting Agreement, dated as of April
26, 2000 (the "Agreement"), by and among E2Enet, Inc., a Delaware corporation
("E2E"), Northwood Capital Partners LLC, a New York limited liability company
("Northwood Capital"), Northwood Ventures LLC, a New York limited liability
company ("Northwood Ventures" and, together with Northwood Capital,
"Northwood"), Jonathan J. Ledecky ("Ledecky"), and each of the other
shareholders of Buyline.net, Incorporated ("Buyline") listed on the signature
pages to the Agreement. Capitalized terms used but not defined herein shall have
the meanings given to such terms in the Agreement.

          Notwithstanding any other provision of the Agreement, effective as of
the fifth (5th) anniversary of the execution of the Agreement, E2E irrevocably
waives Northwood's and Ledecky's obligations under Section 2 of the Agreement
and agrees not to exercise its right to vote any Shares held by Northwood and
Ledecky except as otherwise directed by Northwood and/or Ledecky. In the event
that the Shares held by E2E, Northwood, Ledecky and the Shareholders
collectively represent less than 25% of the Common Stock, and counsel to E2E and
U.S. Technologies Inc. determines that Northwood and Ledecky's obligations under
Section 2 of the Agreement are not reasonably necessary for Buyline to be
considered a "controlled subsidiary" of E2E for purposes of the Investment
Company Act of 1940, as amended, and as in effect from time to time, E2E agrees
to waive such obligations. E2E agrees that any future waivers under the
Agreement shall apply pro rata to Northwood and Ledecky.

         Each of E2E, Northwood and Ledecky agrees to vote its or his respective
Shares to cause the Buyline Board of Directors (the "Board") to be composed of
seven (7) members, including three members nominated by E2E, one member
nominated by Northwood, Edward


<PAGE>   2

                                      -2-


Hauk, Ed Sager and Michael Deale. Northwood's initial representative shall be
Henry T. Wilson.

         At any time from and after the date that is (30) thirty months after
the date of the Agreement, if Northwood and/or Ledecky enter into an agreement
to sell any of their respective Shares pursuant to a bona fide offer by a
non-affiliated third party, E2E agrees, at its option, either (i) to waive
irrevocably its rights to vote any of such Shares being sold by Northwood and/or
Ledecky or (ii) to purchase such Shares being sold by Northwood and/or Ledecky
on the same terms and conditions as those contained in such offer.

         With respect to any sale or disposition by E2E to a third party of any
Shares held by it, Northwood and Ledecky shall have the right to sell to such
third party, on the same terms and conditions as E2E is proposing to sell or
dispose of its Shares, the same proportion of their respective Shares as is
being sold by E2E. E2E shall provide Northwood and Ledecky with prior written
notice of any such sale or disposition, which notice shall include all of the
material terms and conditions of the proposed transfer and copies of each
agreement or other document pursuant to which the transfer will be effected.
Within ten (10) days of receipt of such notice, Northwood and Ledecky shall have
the right, to be exercised by written notice to E2E, to require E2E to cause the
purchaser of E2E's shares to include Northwood or Ledecky's shares as part of
the proposed sale or disposition transaction in accordance with the provisions
of this paragraph.

         Except as expressly modified hereby, all other terms and conditions of
the Agreement remain in full force and effect.
