                         REPRESENTATIONS AND WARRANTIES

         Section 3.1 Representations and Warranties of Lender. Lender hereby
represents and warrants to the Company as follows:

                  1. Authorization; Enforceability. Lender has full power and
authority to enter into this Agreement. This Agreement has been duly and validly
authorized, executed and delivered by Lender and constitutes a legal, valid and
binding obligation of Lender, enforceable against Lender in accordance with its
terms, except as limited by (i) applicable bankruptcy, insolvency,
reorganization, moratorium and other laws of general application affecting the
enforcement of creditors' rights generally, and (ii) laws relating to the
availability of specific performance, injunctive relief and other equitable
remedies.

                  2. Investment Experience. Lender is experienced in evaluating
and investing in securities of companies in the development stage in the normal
course of its business and

                                        3
<PAGE>   4
acknowledges that he is able to fend for himself, can bear the economic risk of
its investment and has such knowledge and experience in financial and business
matters that he is capable of evaluating the merits and risks of the investment
in the Draw Down Note.

                  3. Purchase Entirely for Own Account. This Agreement is made
with Lender in reliance upon Lender's representation to the Company, which by
Lender's execution of this Agreement Lender hereby confirms, that the Draw Down
Note acquired hereunder will be acquired for investment for Lender's account,
not as a nominee or agent, and that Lender has no present intention of selling
the such Draw Down Note and will not sell, grant any participation in, or
otherwise distribute the same in any transaction which is in violation of the
securities laws, rules or regulations of the United States or any state thereof.

                  4. Restricted Securities. Lender understands that the Draw
Down Note has not been, and may not be, registered under the Securities Act
of 1933, as amended (the "Securities Act"), and therefore, cannot be resold
unless it is registered under such Act or unless an exemption from registration
is available.

                  5. Access to Information and Acknowledgment of Risk. Lender
has been afforded by the Company access to information about the Company and the
Company's financial condition, results of operations, business, property,
management and prospects sufficient to enable Lender to evaluate an investment
in the Draw Down Note. This access has included an opportunity to ask questions
of and receive information from the Company and its officers and directors.
Lender acknowledges that he may be required to bear the economic risk of an
investment in the Draw Down Note for an indefinite period, and Lender is able
to bear such risk for an indefinite period. Lender has extensive knowledge of
the business, financial condition and prospects of the Company, and has
conducted his own due diligence on the merits and risks of the proposed
acquisition of the Draw Down Note from the Company.

                  6. Governmental Consents. No consent, approval, qualification,
order or authorization of, or filing with, any local, state or federal
governmental authority is required on the part of Lender in connection with the
valid execution, delivery or performance of this Agreement.

                  7. Compliance With Other Instruments. Lender is not in
violation or default in any material respect of any provision of any mortgage,
agreement, instrument or contract to which he is a party or by which he is
bound, or of any foreign or domestic, federal or state judgment, order, writ,
decree, statute, rule or regulation applicable to Lender, where such default
would restrict the rights of Lender to consummate the transactions contemplated
hereby. The execution, delivery and performance by Lender of this Agreement and
the consummation of the transactions contemplated hereby, will not result in any
such violation or be in material conflict with or constitute, with or without
the passage of time or giving of notice, either a material default under any
such provision, instrument, contract judgment, order, writ or decree.

                                        4
<PAGE>   5
                  8. Manner of Sale. At no time was Lender presented with or
solicited by or through any leaflet, public promotional meeting, television
advertisement or any other form of general solicitation or advertising.

                  9. Financial Capacity. Lender currently has the financial
capacity to meet his obligations to the Company hereunder, and the Lender has no
present knowledge of any circumstances which could cause him to become unable to
meet such obligations in the future.

         Section 3.2 Representation and Warranties of The Company. The Company
hereby represents and warrants to Lender as follows:

                  1. Organization of the Company. The Company is a corporation
duly incorporated and existing in good standing under the laws of the State of
Nevada and has all requisite corporate authority to own its properties and to
carry on its business as now being conducted.

                  2. Authorization; Enforceability. The Company has full power
and authority to enter into this Agreement and to issue the Draw Down Note
hereunder. This Agreement has been duly and validly authorized, executed and
delivered by the Company and constitutes, and when the Draw Down Note has been
duly and validly executed and delivered, such Draw Down Note will constitute,
the legal, valid and binding obligations of the Company, enforceable against the
Company in accordance with their terms, except as limited by (i) applicable
bankruptcy, insolvency, reorganization, moratorium and other laws of general
application affecting enforcement of creditors' rights generally, and (ii) laws
relating to the availability of specific performance, injunctive relief and
other equitable remedies.

                  3. Governmental Consents. To the knowledge of the Company, no
consent, approval qualification, order or authorization of, or filing with, any
local, state or federal governmental authority is required on the part of the
Company in connection with the valid execution, delivery or performance of this
Agreement or of the Draw Down Note.

                  4. Compliance With Other Instruments. The Company is not in
violation or default in any material respect of any provision of its charter or
by laws, or any mortgage, agreement, instrument or contract to which the Company
is a party or by which the Company is bound, or, to the Company's knowledge, of
any foreign or domestic, federal or state judgment, order, writ, decree,
statute, rule or regulation applicable to the Company, where such default would
restrict the rights of the Company to consummate the transactions contemplated
hereby. The execution, delivery and performance by the Company of this
Agreement, and the consummation of the transactions contemplated hereby, will
not result in any such violation or be in material conflict with or constitute,
with or without the passage of time or giving of notice, either a material
default under any such provision, instrument, contract, judgment, order, writ or
decree.

<PAGE>   6
                  5. Private Offering. Subject to the accuracy of Lender's
representations and warranties set forth in Section 3.1, the offer, sale and
issuance of the Draw Down Note, as contemplated by this Agreement, is exempt
from the registration requirements of the Securities Act. The Company agrees
that neither the Company nor anyone acting on its behalf will offer the
Draw Down Note or any similar securities for issuance or sale, or solicit any
offer to acquire any of the same from anyone so as to render the issuance and
sale of such securities subject to the registration requirements of the
Securities Act. The Company shall not offer or sell the Draw Down Note by any
form of general solicitation or general advertising, as such terms are used in
Rule 502(c) under the Securities Act.

                                       12
<PAGE>   13
         For purposes of this Note, the "Maturity Date" shall be the earlier of
(i) [TWO YEAR ANNIVERSARY OF TERMINATION OF COMMITMENT PERIOD] and (ii) delivery
by the Holder to the Company of a Default Notice (as defined in Section 4
herein).

                  3. OVERDUE INTEREST PAYMENTS. Interest on the indebtedness
evidenced by this Note after an Event of Default, or maturity, accelerated or
otherwise, shall be due and payable at the rate of twelve percent (12%) per
annum, subject to the limitations of applicable law.

                  4. EVENTS OF DEFAULT.

                  (1) In the case of any Event of Default (as hereinafter
defined), the Holder may, by notice to the Company specifying such Event of
Default (a "Default Notice"), declare the principal of (and accrued interest, if
any) on this Note to be immediately due and payable and thereupon, this Note
(including both principal and accrued interest, if any) shall become immediately
due and payable. This provision is subject to the condition that if, at any time
after delivery of a Default Notice, the Holder shall rescind or annul such
Default Notice, then such Default Notice and its consequences shall be rescinded
and annulled, but no such rescission or annulment shall extend to or affect any
subsequent default or impair or exhaust any right or power consequent thereon.

                  (2) For purposes of this Note, any one or more of the
following shall constitute an "Event of Default":

                           (a) default in the payment of the principal of (or
interest, if any, on) this Note when the same shall mature or become due and
payable, either by the terms hereof or otherwise; or

                           (b) acceleration, by reason of default, of the
maturity of outstanding indebtedness for money borrowed of the Company in an
amount in excess of $100,000;

                           (c) any judgment, writ or warrant of attachment or of
any similar process in an amount in excess of $100,000 is entered or filed
against the Company or against the property or assets of the Company and remains
unpaid, unvacated, unbonded and unstayed for a period of sixty (60) days; or

                           (d) failure on the part of the Company to duly
observe or perform any of its other material covenants or agreements contained
in, or to cure any material breach in a material representation or covenant
contained in, this Note for a period of ten (10) business days after the date on

has been given by the Holder to the Company.

<PAGE>   14
                  (3)  The occurrence of an Insolvency Event shall
automatically constitute an Event of Default. An "Insolvency Event" shall mean a
decree or order by a court having jurisdiction has been entered adjudging the
Company bankrupt or insolvent, or approving a petition seeking reorganization of
the Company under any applicable bankruptcy law and such decree or order has
continued undischarged or unstayed for a period of thirty (30) days; or a decree
or order of a court having jurisdiction for the appointment of a receiver or
liquidator or trustee or assignee in bankruptcy or insolvency of the Company or
of all or substantially all of its property, or for the winding-up or
liquidation of its affairs, has been entered, and has remained in force
undischarged or unstayed for a period of thirty (30) days. Notwithstanding any
provision in Section 4(a) to the contrary, upon the occurrence of an Insolvency
Event, the Holder shall have no obligation to deliver a Default Notice to the
Company and the principal of (and accrued interest, if any) on this Note shall
be immediately due and payable regardless of whether the Holder shall have
delivered a Default Notice.

                  5. HOLIDAYS. If this Note becomes due and payable on a
Saturday, Sunday or public holiday under the laws of the State of New York, then
such payment may be made on the next succeeding business day with the same force
and effect as if made on the nominal date such payment became due and payable
(and no interest shall accrue for the period after such nominal date).

                  6. SURVIVAL. The agreements, undertakings, representations and
warranties contained in this Note shall remain operative and in full force and
effect and, subject to payment in full of all principal (and accrued interest,
if any) due hereon, shall survive the surrender and/or delivery of this Note to
the Company for cancellation or otherwise in connection with the transfer
hereof. All the covenants, stipulations, promises and agreements contained in
this Note by or on behalf of the Company shall bind its successors and assigns,
whether or not so expressed.

                  7. NOTICES. Except as herein otherwise expressly provided, all
notices, requests, demands, consents and other communications required or
permitted under this Note shall be in writing and shall be considered to have

reasonably believes that it is no longer in its interest to maintain this

specifically designated by Company as confidential, including the design, plans,
specifications, software manuals, customer lists, supplier data, customer data,
cost and price data, marketing information (other than D&B Data) and other
information relating to the Company Directory that is designated as
confidential, whether disclosed to Provider in connection with this Agreement or
otherwise, constitutes valuable confidential and proprietary information of

foregoing, Company Confidential Information shall not include information that
was lawfully disclosed to Provider free of any obligation to keep it
confidential, information that is or that becomes publicly available by other
than unauthorized disclosure and information that is independently developed by
Provider. Provider shall not use or disclose and shall not suffer or permit its
employees, agents or any other parties to use or disclose such Company
Confidential Information other than as contemplated by this Agreement without
Company's prior written consent. Provider shall inform Company promptly after
discovery of any unauthorized use or disclosure of any of the Company
Confidential Information and shall furnish to Company all available information
and reasonably cooperate with Company regarding such disclosure.

          (b) Company acknowledges that the tangible and intangible information
specifically designated by Provider as confidential, including data formats and
layouts, the terms of this Agreement, and other information relating to the D&B
Data, whether disclosed to Company in connection with this Agreement or

that was lawfully disclosed to Company free of any

                                       4
<PAGE>   5
obligation to keep it confidential, information that is or that becomes publicly
available by other than unauthorized disclosure and information that is
independently developed by Company. Company shall not use or disclose and shall
not suffer or permit its employees, agents or any other parties to use or
disclose such Provider Confidential Information other than as contemplated by
this Agreement without Provider's prior written consent. Company shall inform
Provider promptly after discovery of any unauthorized use or disclosure of any
Provider Confidential Information and shall furnish to Provider all available
information and reasonably cooperate with Provider regarding such disclosure.

          (c) Each party recognizes and agrees that its breach of the provisions
of this Paragraph 10 may cause immediate and irreparable harm to the other
party, and that in the event of such breach, the other party, in addition to any
damages to which it may be entitled, shall have the right to seek injunctive
relief against the other party.

     11.  ENTIRE AGREEMENT. This Agreement, including all Schedules, embodies
the entire understanding between the parties with respect to the subject matter
hereof and supersedes any and all prior understandings and agreements, oral or
written, relating thereto. Any amendment to this Agreement, including its
Schedules, must be in writing and signed by each party.

     12.  DEFAULT. Upon the breach of any material obligation under this
Agreement by either party, the aggrieved party may give to the defaulting party
written notice of such breach, which notice shall specify the exact nature of
the breach and shall expressly state the aggrieved party's intention to
terminate this Agreement in the event the breach is not remedied and any damages
to be paid within ten (10) days after the receipt of such notice. If, after the
expiration of such period, the defaulting party has failed or refuses to remedy
such breach and to pay the damages caused thereby, this Agreement may be
terminated forthwith, effective upon dispatch of notice by the aggrieved party
to the defaulting party. The right of either party to terminate this Agreement
on default is not an exclusive remedy, and an aggrieved party shall be entitled
alternatively or cumulatively to seek damages for breach of this Agreement, to
seek an order requiring performance of the obligations of this Agreement, or to
seek any other appropriate remedy.

     13.  NOTICES. Every notice or other communication required or contemplated
by this Agreement by either party shall be delivered in person or sent by
postage prepaid mail, which shall be air mail if posted in a country other than
that of the addressee, telex, facsimile transmission, express delivery or
courier, addressed to the party for whom intended at the address specified at
the beginning of this Agreement or at such other address as the intended
recipient previously shall have designated by written notice to the other party.
Notice shall be effective on delivery. Notice not given in writing shall be
effective only if explicitly or implicitly acknowledged in writing by the party
to whom it was given.

     14.  ASSIGNMENT. This Agreement shall not be assigned by either party
without the other party's prior written consent, except that Provider may assign
this Agreement to a successor corporation that results from a merger or
corporate reorganization, or to its parent or any affiliate, without such
consent.

     15.  SEVERABILITY. Should any provision of this Agreement be held to be
void, invalid, unenforceable or illegal by a court, the validity and
enforceability of the other provisions shall not be affected thereby.

     16.  NO WAIVER. Failure of either party at any time to require performance
by the other party of any obligation under this Agreement shall not affect the
right of such party to require performance of that obligation. Any waiver by
either party of any breach of any provision of this Agreement shall not be
construed as a waiver of any continuing or succeeding breach of such provision,
a waiver or modification of the provision itself, or a waiver of modification of
any right under this Agreement.

     17.  GOVERNING LAW. This Agreement shall be governed by and construed under
the law of the State of New Jersey.
