THIS CONVERTIBLE PROMISSORY NOTE MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR

                           CONVERTIBLE PROMISSORY NOTE

$250,000.00                                               September 25, 2000
                                                          Hightstown, New Jersey

         For value received, NAI Direct, Inc., a Delaware corporation (the
"Borrower"), hereby unconditionally promises to pay to the order of Worldwide
Web NetworX Corporation, a Delaware corporation, 521 Fellowship Road, Suite 130,
Mt. Laurel, New Jersey 08054 (the "Lender"), subject to the provisions set forth
in Sections 6 and 7, in lawful money of the United States of America and in
immediately available funds, the principal sum of $250,000.00 (the "Loan")
payable on the date and in the manner set forth below.

                  1. PRINCIPAL REPAYMENT. The outstanding principal amount of
         the Loan shall be payable in full on or before September 25, 2004 (the
         "Maturity Date"), subject to the conversion of this Note into certain
         shares of the common capital stock of New America Network, Inc., a
         Delaware corporation ("NAI"), as described in Sections 6 and 7 below.

                  2. INTEREST RATE. The Borrower further promises to pay
         interest on the sum of the unpaid principal balance of the Loan
         outstanding on each day, from the date of this Note until all of the
         principal shall have been repaid in full or, at the option of the
         Lender, converted into capital stock of NAI. Subject to the provisions
         hereof, the unpaid principal balance of this Note shall bear interest
         from the date hereof at the Applicable Federal Rate, as defined by
         Section 1274(d)(1) of the Internal Revenue Code, as amended (the
         "INTEREST RATE"); PROVIDED, HOWEVER, that in addition to all other
         rights contained in this Note, if a default in the payment of any of
         the obligations evidenced by this Note (the "Obligations") occurs, all
         outstanding Obligations shall bear interest at the amount of the
         Interest Rate plus 4% (the "DEFAULT RATE"). The Default Rate shall also
         apply from the Maturity Date until the Obligations or any judgment
         thereon is paid in full. Interest shall be payable on the Maturity Date
         and shall be calculated on the basis of a 365-day year for the actual
         number of days elapsed.

                  3. PLACE OF PAYMENT. All amounts payable hereunder shall be
         payable to the Lender in the manner specified by the Lender to the
         Borrower in writing. In the event that payment is to be made by wire
         transfer, such payment shall be made on a day that banks are open for
         business in New York, New York (each, a "Business Day"). If any payment
         shall be made on the next succeeding Business Day, and such extension
         shall be included in computing interest in connection with such
         payment.
<PAGE>

                  4. PREPAYMENT. The Loan may be prepaid by the Borrower, in
         whole or in part, without premium or penalty, at any time prior to the
         Borrower's receipt of written notice of the Lender's election to
         exercise its conversion rights under the following Section 6.
         Notwithstanding anything contained herein to the contrary, the
         Borrower's failure to pay this Note in full within 10 days after the
         Lender's receipt of written notice of the Borrower's election to
         exercise its prepayment right pursuant to this Section 4 hereof shall
         not constitute an Event of Default hereunder and, in such event, this
         Note and all of its provisions shall remain in full force and effect as
         if such notice had not been given by the Borrower.

                  5. APPLICATION OF PAYMENT. All payments received by the Lender
         shall be applied as follows: (First) to the payment of accrued and
         unpaid interest, and (Second) to the payment of principal. If any
         payment received by the Lender under this Note is rescinded, avoided or
         for any reason returned by the Lender because of any adverse claim or
         threatened action, the returned payment shall remain payable as an
         obligation under this Note as though such payment had not been made.

                  6. CONVERSION RIGHTS. At any time prior to the Lender's
         receipt of written notice of the Borrower's election to exercise its
         prepayment right pursuant to Section 4 hereof, provided that full
         prepayment is received by the Lender within 10 days after its receipt
         of such notice, and from time to time prior to the Maturity Date (the
         "Conversion Period"), the Lender shall have the right to convert all or
         any part of the outstanding principal balance and accrued interest
         under this Note into shares of the common stock of NAI ("Shares"),
         which shall be valued, for that purpose, at the lesser of Current
         Market Value of the Shares or $5.00 per Share (the "Exercise Price"),
         subject to adjustment in accordance with the provisions set forth in
         Exhibit "A" attached hereto. In the event the Lender elects to exercise
         its rights under this Section 6, the Lender shall deliver to the
         Borrower written notice of its decision and NAI shall promptly deliver
         to the Lender the certificate(s) representing the Shares to the address
         specified by the Lender to the Borrower in writing. The Lender shall
         have registration rights with respect to the Shares as set forth in
         Exhibit "B" attached hereto.

                  7. MECHANICS OF CONVERSION. Upon conversion of the entire
         principal balance of and all accrued interest under this Note, this
         Note shall become fully paid and satisfied, and the Lender shall
         surrender this Note, duly endorsed, to the Borrower's office or such
         other address which the Borrower shall designate against delivery of
         the certificates representing the capital stock of NAI.

                  8. ISSUE TAXES. The Borrower shall pay any and all issue and
         other taxes that may be payable with respect to any issue or delivery
         of shares of capital stock on conversion of this Note pursuant hereto;
         provided, however, that the Borrower shall not be obligated to pay any
         transfer taxes resulting from any transfer requested by any holder in
         connection with any such conversion.

                  9. FRACTIONAL SHARES. No fractional shares shall be issued
         upon the conversion of this Note. All shares of capital stock
         (including fractions thereof) issuable upon conversion of this Note,
         along with any other Notes held by the Lender shall be
<PAGE>

         aggregated for purposes of determining the number of whole shares
         issuable upon conversion. In lieu of issuing any fractional shares, the
         Borrower shall pay to the Lender in cash any remainder resulting after
         the number of whole shares is determined as a result of the conversion.

                  10. DEFAULT. It shall be an event of default hereunder (an
         "Event of Default") if:

                  a) The Borrower shall fail to make any payment due under this
Note, promptly when due; or

                  b) The Borrower shall commit, or suffer, any other default
under this Note or the agreement, dated of even date herewith, by and among the
Borrower, the Lender, Real Quest, Inc., New America Network, Inc., Gerald C.
Finn and Jeffrey Finn, and the Borrower shall fail to cure such default within
10 days following the Borrower's receipt of written notice from the Lender.

         If an Event of Default should occur, the Lender may, at its option,
without demand upon or notice to the Borrower, declare the full amount of the
principal sum remaining unpaid to be due and payable immediately, with interest
as aforesaid, anything to the contrary herein notwithstanding; and payment of
the same may be enforced and recovered in whole or in part at any time, at the
option of the Lender, by the entry of judgment on this Note and/or the issuance
of execution thereon upon any real of personal property of the Borrower and/or
by exercising any other rights or remedies available to the Lender by law.

         11. WAIVER. The Borrower waives presentment and demand for payment,

the benefit of and be binding on any successor to the Borrower and shall extend
to any permitted holder hereof.

shall be construed to be a waiver of the right to insist upon prompt payment
thereafter or to impose late charges retroactively or prospectively or shall be
deemed a novation of this Note or as a reinstatement of the debt evidenced
hereby or the waiver of such right of acceleration or any other right; and the
Borrower hereby expressly waives the benefit of any statute or rule or law or
equity which would produce a result contrary or in conflict with the foregoing.

<PAGE>

                                    EXHIBIT A

This is Exhibit A to the Convertible Promissory Note, dated September 25, 2000,
in the original principal amount of $250,000, executed and delivered by NAI
Direct, Inc. to WorldWide Web NetworX Corporation (the "Note").

                            ANTI-DILUTION PROVISIONS

         1. The Exercise Price and the number of Shares issuable to the Lender
upon the exercise of the Lender's conversion rights, as set forth in Section 6
of the Note, shall be subject to adjustment from time to time upon the happening
of certain events as follows:

           (a) In case New America Network, Inc. (the "Company") shall hereafter
(i) declare a dividend or make a distribution on its outstanding shares of
common stock ("Common Stock") in shares of Common Stock, (ii) subdivide or
reclassify its outstanding shares of Common Stock into a greater number of
shares, or (iii) combine or reclassify its outstanding shares of Common Stock
into a smaller number of shares, the Exercise Price in effect at the time of the
record date for such dividend or distribution or of the effective date of such
subdivision, combination or reclassification shall be adjusted so that it shall
equal the price determined by multiplying the Exercise Price by a fraction, the
denominator of which shall be the number of shares of Common Stock outstanding
after giving effect to such action, and the numerator of which shall be the
number of shares of Common Stock outstanding immediately prior to such action.
Such adjustment shall be made successively whenever any event listed above shall
occur.

           (b) In case the Company shall fix a record date for the issuance of
rights or warrants to all holders of its Common Stock entitling them to
subscribe for or purchase shares of Common Stock (or securities convertible into
Common Stock) at a price (the "Subscription Price") (or having a conversion
price per share) less than the Current Market Value (as defined hereafter) or
less than the Exercise Price on such record date, the Exercise Price shall be
adjusted so that the same shall equal the lower of (i) the price determined by
multiplying the Exercise Price in effect immediately prior to the date of such
issuance by a fraction, the numerator of which shall be the sum of the number of
shares of Common Stock outstanding on the record date mentioned below and the
number of additional shares of Common Stock which the aggregate offering price
of the total number of shares of Common Stock so offered (or the aggregate
conversion price of the convertible securities so offered) would purchase at
such Current Market Value per share of the Common Stock (as defined hereafter),
and the denominator of which shall be the sum of the number of shares of Common
Stock outstanding on such record date and the number of additional shares of
Common Stock offered for subscription or purchase (or into which the convertible
securities so offered are convertible) or (ii) in the event the Subscription
Price is equal to or higher than the Current Market Value but is less than the
Exercise Price, the price determined by multiplying the Exercise Price in effect
immediately prior to the date of issuance by a fraction, the numerator of which
shall be
<PAGE>

the sum of the number of shares outstanding on the record date mentioned below
and the number of additional shares of Common Stock which the aggregate offering
price of the total number of shares of common stock so offered (or the aggregate
conversion price of the convertible securities so offered) would purchase at the
Exercise Price in effect immediately prior to the date of such issuance, and the
denominator of which shall be the sum of the number of shares of Common Stock
outstanding on the record date mentioned below and the number of additional
shares of Common Stock offered for subscription or purchase (or into which the
convertible securities so offered are convertible). Such adjustment shall be
made successively whenever such rights or warrants are issued and shall become
effective immediately after the record date for the determination of
shareholders entitled to receive such rights or warrants; and to the extent that
shares of Common Stock are not delivered (or securities convertible into Common
Stock are not delivered) after the expiration of such rights or warrants the
Exercise Price shall be readjusted to the Exercise Price which would then be in
effect had the adjustments made upon the issuance of such rights or warrants
been made upon the basis of delivery of only the number of shares of Common
Stock (or securities convertible into Common Stock) actually delivered.

           (c) In case the Company shall hereafter distribute to the holders of
its Common Stock evidences of its indebtedness or assets (excluding cash
dividends or distributions and dividends or distributions referred to in
Subsection (a) above) or subscription rights or warrants (excluding those
referred to in Subsection (b) above), then in each such case the Exercise Price
in effect thereafter shall be determined by multiplying the Exercise Price in
effect immediately prior thereto by a fraction, the numerator of which shall be
the total number of shares of Common Stock outstanding multiplied by the Current
Market Value per share of Common Stock (as defined hereafter), less the fair
market value (as reasonably determined by the Company's Board of Directors) of
said assets or evidences of indebtedness so distributed or of such rights or
warrants, and the denominator of which shall be the total number of shares of
Common Stock outstanding multiplied by such Current Market Value per share of
Common Stock. Such adjustment shall be made successively whenever such a record
date is fixed. Such adjustment shall be made whenever any such distribution is
made and shall become effective immediately after the record date for the
determination of shareholders entitled to receive such distribution.

           (d) In case the Company shall hereafter issue shares of its Common
Stock (excluding shares issued (i) in any of the transactions described in
Subsection (a) above, (ii) upon exercise of options granted to the Company's
officers, directors, employees and consultants (other than Gerald Finn or
Jeffrey Finn) under a plan or plans adopted by the Company's Board of Directors
and approved by its shareholders, if such shares would otherwise be included in
this Subsection (d), (but only to the extent that the aggregate number of shares
excluded hereby and issued after the date hereof shall not exceed 10% of the
Company's Common Stock outstanding at the time of any issuance), (iii) upon
exercise of options, warrants, convertible securities and convertible debentures
outstanding as of September 14, 2000, (iv) to shareholders of any corporation
which merges into the Company in proportion to their stock holdings of such
corporation immediately prior to such merger, upon such merger, (v) issued in a
private placement, or
<PAGE>

upon exercise or conversion of any securities issued in or in connection with
such a private placement (including agent, consulting or advisory), where the
Offering Price (as defined below) is at least 90% of the Current Market Value,
(vi) issued in a bona fide public offering pursuant to a firm commitment
underwriting, but only if no adjustment is required pursuant to any other
specific subsection of this Section 1 (without regard to Subsection (i) below)
with respect to the transaction giving rise to such rights) for a consideration
per share (the "Offering Price") less than the Current Market Value, the
Exercise Price shall be adjusted immediately thereafter so that it shall equal
the lower of (i) the price determined by multiplying the Exercise Price in
effect immediately prior thereto by a fraction, the numerator of which shall be
the sum of the number of shares of Common Stock outstanding immediately prior to
the issuance of such additional shares and the number of shares of Common Stock
which the aggregate consideration received (determined as provided in subsection
(i) below) for the issuance of such additional shares would purchase at such
Current Market Value per share of Common Stock (as defined in subsection (h)
below), and the denominator of which shall be the number of shares of Common
Stock outstanding immediately after the issuance of such additional shares or
(ii) in the event the Offering Price is equal to or higher than the Current
Market Value per share but less than the Exercise Price, the price determined by
multiplying the Exercise Price in effect immediately prior to the date of
issuance by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding immediately prior to the issuance of such additional
shares and the number of shares of Common Stock which the aggregate
consideration received (determined as provided in subsection (g) below) for the
issuance of such additional shares would purchase at the Exercise Price in
effect immediately prior to the date of such issuance, and the denominator of
which shall be the number of shares of Common Stock outstanding immediately
after the issuance of such additional shares. Such adjustment shall be made
successively whenever such an issuance is made.

           (e) In case the Company shall hereafter issue any securities
convertible into or exchangeable for its Common Stock (excluding securities
issued in transactions described in Subsections (b) and (c) above for a
consideration per share of Common Stock (the "Exchange Price") initially
deliverable upon conversion or exchange of such securities (determined as
provided in Subsection (g) below) less than the Current Market Value, the
Exercise Price shall be adjusted immediately thereafter so that it shall equal
the lower of (i) the price determined by multiplying the Exercise Price in
effect immediately prior thereto by a fraction, the numerator of which shall be
the sum of the number of shares of Common Stock outstanding immediately prior to
the issuance of such securities and the number of shares of Common Stock which
the aggregate consideration received for such securities would purchase at such
Current Market Value per share of Common Stock, and the denominator of which
shall be the sum of the number of shares of Common Stock outstanding immediately
prior to such issuance and the maximum number of shares of Common Stock of the
Company deliverable upon conversion of or in exchange for such securities at the
initial conversion or exchange price or rate, or (ii) in the event the
Conversion Price is equal to or higher than the Current Market Value per share
but less than the Exercise Price, the price determined by multiplying the
Exercise Price in effect immediately prior to the date of issuance by a
fraction, the numerator of which shall be the sum of the number of shares
outstanding immediately prior to the issuance of such

<PAGE>

securities and the number of shares of Common Stock which the aggregate
consideration received (determined as provided in subsection (g) below) for such
securities would purchase at the Exercise Price in effect immediately prior to
the date of such issuance, and the denominator of which shall be the sum of the
number of shares of Common Stock outstanding immediately prior to the issuance
of such securities and the maximum number of shares of Common Stock of the
Company deliverable upon conversion of or in exchange for such securities at the
initial conversion or exchange price or rate. Such adjustment shall be made
successively whenever such an issuance is made.

           (f) Whenever the Exercise Price is adjusted pursuant to Subsections
(a), (b), (c), (d) and (e) above, the number of Shares acquired by the exercise
of the Lender's conversion rights shall simultaneously be adjusted by
multiplying the number of Shares initially issuable upon exercise of the
conversion rights by the Exercise Price in effect on the date hereof and
dividing the product so obtained by the Exercise Price, as adjusted.

           (g) For purposes of any computation respecting consideration received
pursuant to Subsections (d) and (e) above, the following shall apply:

                  (A)      in the case of the issuance of shares of Common Stock
                           for cash, the consideration shall be the amount of
                           such cash, provided that in no case shall any
                           deduction be made for any commissions, discounts or
                           other expenses incurred by the Company for any
                           underwriting of the issue or otherwise in connection
                           therewith;

                  (B)      in the case of the issuance of shares of Common Stock
                           for a consideration in whole or in part other than
                           cash, the consideration other than cash shall be
                           deemed to be the fair market value thereof as
                           determined in good faith by the Board of Directors of
                           the Company (irrespective of the accounting treatment
                           thereof), whose determination shall be conclusive;
                           and

                  (C)      in the case of the issuance of securities convertible
                           into or exchangeable for shares of Common Stock, the
                           aggregate consideration received therefor shall be
                           deemed to be the consideration received by the
                           Company for the issuance of such securities plus the
                           additional minimum consideration, if any, to be
                           received by the Company upon the conversion or
                           exchange thereof (the consideration in each case to
                           be determined in the same manner as provided in
                           clauses (A) and (B) of this Subsection (g)).
<PAGE>

           (h) For the purpose of any computation under Subsections (b), (c),
(d) and (e) above and (j) below, the Current Market Value per share of Common
Stock at any date shall be determined in the manner set forth in Section 2
hereof except that the Current Market Value per share shall be deemed to be the
higher of (i) the average of the prices for 30 consecutive business days before
such date or (ii) the price on the business day immediately preceding such date.

           (i) No adjustment in the Exercise Price shall be required unless such
adjustment would require an increase or decrease of at least five cents ($0.05)
in such price; provided, however, that any adjustments which by reason of this
Subsection (i) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment required to be made hereunder. All
calculations shall be made to the nearest cent or to the nearest one-hundredth
of a share, as the case may be.

           (j) Notwithstanding the provisions contained herein, in the event
that the Company shall at any time issue securities that would result in an
adjustment under Subsections (b), (d) or (e) having an Offering Price,
Subscription Price or Conversion Price less than the Exercise Price (whether
initially or due to provisions in such securities requiring price reductions as
a result of anti-dilution adjustments, the passage of time, "discount to market"
or similar provisions), then the Exercise Price shall be immediately reset to
equal such lower Offering Price, Subscription Price or Conversion Price, as
applicable, and the number of shares issuable upon exercise of the Lender's
conversion rights shall be adjusted accordingly.

           (k) No adjustment under Subsections (b), (c), (d) and (e) shall be
required for issuances below the Current Market Value if (A) the Current Market
Value is at least 300% of the Exercise Price then in effect and (B) a
registration statement covering the Shares is in effect and remains in effect
for the 90 days after such issuance or Rule 144(k) under the Securities Act of
1933, as amended (the "Act") is available for resale of all of the Shares.

           (l) Whenever the Exercise Price is adjusted, as herein provided, the
Company shall promptly, but in no event later than 10 days after any request for
such an adjustment by the Lender, cause a notice setting forth the adjusted
Exercise Price and adjusted number of Shares issuable upon exercise of the
Lender's conversion rights and, if requested, information describing the
transactions giving rise to such adjustments, and shall cause a certified copy
thereof to be mailed to the Lender. The Company may retain a firm of independent
certified public accountants selected by the Board of Directors (who may be the
regular accountants employed by the Company) to make any computation required
herein, and a certificate signed by such firm shall be conclusive evidence of
the correctness of such adjustment.

           2. For purposes hereof, the Current Market Value of a share of Common
Stock shall be determined as follows:

If the Common Stock is listed on a national securities exchange or admitted to
unlisted trading privileges on such exchange or listed for trading on the Nasdaq
National Market
<PAGE>

System ("NMS"), the Current Market Value shall be the average of the last
reported sale prices of the Common Stock on such exchange for the 10 trading
days prior to the date of exercise of the Lender's conversion rights; provided
that if no such sale is made on a day within such period or no closing sale
price is quoted, that day's market value shall be the average of the closing bid
and asked prices for such day on such exchange or system; or

If the Common Stock is listed in the over-the-counter market (other than on NMS)
or admitted to unlisted trading privileges, the Current Market Value shall be
the mean of the last reported bid and asked prices reported by the National
Quotation Bureau, Inc. for the 10 trading days prior to the date of the exercise
of this Warrant; or

If the Common Stock is not so listed or admitted to unlisted trading privileges
and bid and asked prices are not so reported, the Current Market Value shall be
an amount determined in a reasonable manner by the Board of Directors of the
Company.

permissible under the Securities Act and subject to the conditions of the
Securities Act (a "Registration"). The Company shall not be obligated to effect
more than one Registration of Registrable Securities hereunder. If a
Registration is an underwritten registration initiated by the Company, and the
managing underwriters shall give written advice to the Company that, in their
opinion, market conditions dictate that no more than a specified maximum number
of securities (the "Underwriter's Maximum Number") could successfully be

proposes to offer and sell for its own account in such registration and the
number of Registrable Securities requested to be included in any such
registration by all Holders exceeds the Underwriter's Maximum Number, then the
Company will include in such registration that number of shares of Registrable
Securities which the Holders have requested to be registered and the securities

over-allotment shall also be allocated between the Company and the Holders on a
pro rata basis.

       (b) REGISTRATION STATEMENT FORM. The Company shall, if permitted by law,
effect any Registration requested under Section 2 by the filing of a

Instruction I.B.3 of Commission Form S-3.

       (c) EXPENSES. Except as otherwise provided herein, the Company shall pay
all Registration Expenses incurred in connection with any Registration.

       (d) EFFECTIVE REGISTRATION STATEMENT. A Registration requested pursuant
to Section 2(a) shall not be deemed to have been effected unless it has become
effective with the Commission. Notwithstanding the foregoing, a registration
statement will not be deemed to have been effected if: (i) after it has become
effective with the Commission, such registration is interfered with by any stop
order, injunction, or other order or requirement of the Commission or other
governmental agency or any court proceeding for any reason other than a
misrepresentation or omission by any Holder; or (ii) the

                                       2
<PAGE>

conditions to closing specified in the underwriting agreement entered into in
connection with such registration are not satisfied in any material respect,

have the right to withdraw any registration before it becomes effective, for any
reason.

registration statement to effect such registration and use its best efforts to
cause such registration to become and remain effective;

                (ii) prepare and file with the Commission such amendments and

earlier of such time as all of such securities have been disposed of in
accordance with the intended methods of disposition by the seller or sellers
thereof set forth in such registration statement or the expiration of 90 days
after such registration statement becomes effective;

                (iii) furnish to the Holders such number of conformed copies of
such registration statement and of each such amendment and supplement thereto
(in each case including all exhibits), such number of copies of the prospectus
contained in such registration statement (including each preliminary prospectus
and any summary prospectus) and any other prospectus filed under Rule 424 under

Securities to be sold under such registration statement may reasonably request;

                (iv) register or qualify all Registrable Securities covered by

statement to consummate the intended disposition of such Registrable Securities;

                (vi) in the event of the issuance of any stop order suspending
the effectiveness of the registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Registrable Securities included in such registration statement for sale in
any jurisdiction, the Company shall use its best efforts promptly to obtain the
withdrawal of such order;

                (vii) furnish to the Holders of Registrable Securities to be
sold under such registration statement copies of any opinion(s) addressed to the
underwriters obtained by the Company from the independent counsel representing
the Company for the purposes of such registration and/or letter(s) obtained from
the independent certified public accountants of the Company, addressed to the
underwriters, stating that they are independent certified public accountants
within the meaning of the Securities Act and that in the opinion of such
accountants, the financial statements and other financial data of the Company
included in the registration statement or the prospectus, or any amendment or
supplement thereto, comply as to form in all material respects with the
applicable accounting requirements of the Securities Act.

                (viii) to the extent required by law, promptly notify the
Holders of Registrable Securities included in such registration statement at any
time when a prospectus relating thereto is required to be delivered under the
Securities Act, of the happening of any event as result of which the prospectus
included in such registration statement, as then in effect, includes an untrue
statement of material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances under which they were made, and at the request of the
Holders promptly prepare and furnish to the Holders a reasonable number of
copies of a supplement to or an amendment of such prospectus as may be necessary
so that, as thereafter delivered to the purchasers of such securities, such
prospectus shall not include an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances under which
they were made;

                (ix) otherwise comply with all applicable rules and regulations
of the Commission, and make available to the Holders, as soon as reasonably
practicable, an earnings statement covering the period of at least twelve (12)
months, but not more than eighteen months, beginning with the first full
calendar month after the effective date of such registration statement, which
earnings statement shall satisfy the provisions of Section 11(a) of the
Securities Act and Rule 158 thereunder, and not file any amendment or supplement
to such registration statement or prospectus to which any Holder shall have
reasonably objected in writing on the grounds that such amendment or supplement
does not comply in all material respects with the requirements of the Securities
Act or of

                                       4
<PAGE>

the rules or regulations thereunder, having been furnished with a copy thereof
at least two business days prior to the filing thereof;

                (x) provide a transfer agent for all Registrable Securities
covered by such registration statement not later than the effective date of such

sold under such registration statement, at the Company's expense, to furnish the
Company with such information and undertakings as it may reasonably request
regarding such Holder and the distribution of such securities as the Company may
from time to time reasonably request in writing.

       4. COVENANTS RELATING TO RULE 144.

       With a view to making available the benefits of certain rules and
regulations of the Commission which may at any time permit the sale of
securities of the Company to the public without registration after such time as
a public market exists for the Common Stock of the Company, the Company agrees:

       (a) to make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act, at all times after
the effective date of the first registration under the Securities Act filed by
the Company for an offering of its securities to the general public;

       (b) to use its best efforts to then file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act, as amended (at any time after it has become
subject to such reporting requirements); and

       (c) so long as a Holder owns any Registrable Securities, to furnish to
the Holder forthwith upon request a written statement by the Company as to its
compliance with the reporting requirements of said Rule 144 (at any time after
90 days after the effective date of the first registration statement filed by
the Company for an offering of its securities to the general public), and of the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements) a copy of the most recent annual or quarterly
report of the Company, and such other reports and documents of the Company as a

the Commission allowing a Holder to sell any such securities without
registration.

                                                                     Exhibit 4.3

                           UNLIMITED SURETY AGREEMENT

TO:      WORLDWIDE WEB NETWORX CORPORATION ("WWWX")

         In consideration of WWWX making a loan to NAI DIRECT, INC., a Delaware
corporation (hereinafter referred to as "DEBTOR"), the undersigned surety (the
"Undersigned"), being financially interested in the affairs of Debtor and
intending to be legally bound hereby, unconditionally becomes surety to WWWX,
its successors, endorsers or assigns for the prompt payment when due of all
monies now or hereafter due to WWWX arising out of the loan evidenced by the
Convertible Promissory Note, in the original principal amount of $250,000, dated
of even date herewith (the "NOTE"), by Debtor, whether at maturity, or by
declaration, acceleration or otherwise, together with costs and expenses of
collection incurred by WWWX, including without limitation reasonable attorneys'
fees, incurred by WWWX in connection with any of the foregoing ("LIABILITIES").

         This Surety is made as separate and independent security for the
payment of the Note and all extensions or modifications of same made by Debtor
to WWWX and the acceptance of this Surety shall not constitute a waiver of any
rights of WWWX under the terms of the Note. All rights and remedies of WWWX
hereunder and under the Note are cumulative and concurrent and may be exercised
singly, successively or concurrently, at the discretion of the WWWX.

         This Surety shall continue until the Debtor or the Undersigned shall
pay in full all Liabilities and shall continue in force until the earlier of
complete payment in full of all Liabilities.

         All of the Liabilities shall become immediately due and payable by the
Undersigned, anything contained herein to the contrary notwithstanding,
immediately upon the happening of any Event of Default under the Note beyond any
applicable notice and grace periods or upon the insolvency of the Debtor; the
application for appointment of a trustee, receiver, conservator, liquidator, or
other judicial representative, similar or dissimilar, for Debtor or any of its
assets; Debtor making any assignment for the benefit of creditors; the
commencement of a case by or against Debtor under any insolvency, bankruptcy,
creditor adjustment or debtor rehabilitation laws, state or federal, including
but not limited to liquidation or reorganization except, if commenced against
Debtor and not dismissed within sixty (60) days thereof; the calling of a
meeting of creditors of Debtor; the commencement of levy, execution or
attachment proceedings against Debtor or any of their assets and such proceeding
are not dismissed within thirty (30) days thereof; whether or not WWWX has
exercised any option which it may have to require payment in full or
acceleration of payment of the Liabilities from any other person liable for
payment of the Liabilities.

         The Undersigned waives: (a) all notices, including but not limited to
(i) notice of acceptance of this Surety, and (ii) notice of presentment, demand
for payment, or protest of any of the Liabilities, or the obligation of any
person, firm or corporation held by WWWX as collateral security; (b) all
defenses, offsets and counterclaims which the Undersigned may at any time have
jointly or severally to any of the Liabilities; (c) trial by jury and the right
thereto in any action or proceeding of any kind, whether arising on, out of,
under of by reason of this Surety or

                                       2
<PAGE>

any other agreement or transaction between the Undersigned, WWWX and/or Debtor;
(d) all notices of the financial condition or of any adverse or other change in
the financial condition of Debtor; and (e) any rights which they may have under
the theory of marshalling.

         WWWX shall have the right to proceed against the Undersigned
immediately upon any default by Debtor and shall not be required to take any
action or proceeding of any kind against Debtor before proceeding against the
Undersigned hereunder.

         WWWX shall have the right, from time to time and at any time, in its
sole discretion, without notice to or consent from the Undersigned, and without
affecting, impairing or discharging, in whole or in part, Liabilities of the
Undersigned hereunder, to modify, change or supplement, in any respect whatever,
any indebtedness or evidence thereof, or any agreement or transaction between
WWWX and Debtor; to grant extensions of time and other indulgences of any kind
to Debtor; to compromise, release, substitute, exercise, enforce or fail or
refuse to exercise or enforce any claims, rights or remedies of any kind which
WWWX may have at any time against Debtor.

         The Undersigned represents that, at the time of the execution and
delivery of this Surety, nothing exists to impair the effectiveness of the
obligations of the Undersigned to WWWX hereunder or the immediate taking effect
of this Surety between the Undersigned and WWWX with respect to becoming
sureties for the Liabilities.

         The Undersigned agrees and consents to the jurisdiction of the Courts
of the State of Delaware and/or the United States District Court for the
District of Delaware in any and all actions and proceedings, whether arising
hereunder or under any other agreement or undertaking, and irrevocably agrees to
service of process by certified mail, return receipt requested, to such address
as may appear in WWWX's records.

         If the Undersigned shall advance any sums to Debtor or its successors
or assigns, or if Debtor or its successors or assigns shall be or shall
hereafter become indebted to the Undersigned, such sums and indebtedness shall
be subordinate in all respects to the amounts then or thereafter due and owing
to WWWX for Debtor's Liabilities. Notwithstanding any payments made by or for
the account of the Undersigned pursuant to this Surety, nothing herein contained
shall be construed to give the Undersigned any right of subrogation in and to
WWWX's rights under or interest in the Liabilities until all amounts owing to
WWWX have been paid in full.

         If a claim is ever made upon the WWWX for repayment or recovery of any
amount or amounts received by the WWWX in payment or on account of any of the
Liabilities of the Debtor and WWWX repays all or part of said amount by reason
of (a) any judgment, decree or order of any court or administrative body having
jurisdiction over WWWX or any of its property, or (b) any settlement or
compromise of any such claim effected by WWWX with any such claimant (including
Debtor), then, and in such event, the Undersigned agrees that any such
<PAGE>

judgment, decree, order, settlement or compromise shall be binding upon the
Undersigned, notwithstanding any revocation hereof or the cancellation of any
note or other instrument evidencing any Liability of Debtor, and the Undersigned
shall be and remain liable to the WWWX hereunder for the amount so repaid or
recovered to the same extent as if such amount had never originally been
received by the WWWX.

         The waiver of any right by WWWX or failure to exercise promptly any
right shall not be construed as the waiver of any other right to exercise the
same at any time thereafter.

         The liability of the Undersigned hereunder shall inure to the benefit
of the WWWX, its successors and assigns.

         All rights and remedies of WWWX are cumulative and not alternative.
This Surety shall be governed by and construed under the laws of the State of
Delaware.

         No waiver of any rights, or powers of WWWX or consent by it shall be
valid unless in writing, signed by an authorized officer.
