                        REPRESENTATIONS AND WARRANTIES

     Section 2.1  Representation and Warranties of the Company.  The Company
hereby makes the following representations and warranties to each of the
Purchasers:

          (a)  (i)  Organization, Good Standing and Power.  The Company is a
corporation duly incorporated, validly existing and in good standing under the
laws of the State of Delaware and has the requisite corporate power to own,
lease and operate its properties and assets and to conduct its business and any
other business presently proposed to be conducted.  The Company does not have
any subsidiaries except as set forth in the Company's Form 10-KSB for the year
ended December 31, 1998, including the accompanying financial statements (the
"Form 10-KSB"), or on Schedule 2.1(a) hereto.  The Company and each such
subsidiary is duly qualified as a foreign corporation to do business and is in
good standing in every jurisdiction in which the nature of the business
conducted or property owned by it makes such qualification

                                       2
<PAGE>

necessary, except for any jurisdiction(s) (alone or in the aggregate) in which
the failure to be so qualified would not have a Material Adverse Affect (as
defined in Section 2.1(e) hereof).

               (ii) Except as set forth in Schedule 2.1(a) hereto, each of the
Company and its subsidiaries has all requisite corporate power and authority and
all franchises, licenses, permits, consents, authorizations, regulatory
approvals and other approvals necessary to own and operate its properties, to
carry on its business and any other businesses presently proposed to be
conducted and to carry out the transactions contemplated by this Agreement,
except where the failure to possess such franchises, licenses, permits,
consents, authorizations, regulatory approvals and other approvals, individually
or in the aggregate, could not reasonably be expected to have a Material Adverse
Effect.  All such franchises, licenses, permits, consents, authorizations,
regulatory approvals and other approvals are valid and in full force and effect,
and the Company has duly performed and is in compliance in all material respects
with all of its obligations thereunder.  No event has occurred with respect to
any of such franchises, licenses, permits, consents, authorizations, regulatory
approvals or other approvals that allows, or after notice or lapse of time or
both would allow, the suspension, limitation, revocation, non-renewal or
termination thereof that, individually or in the aggregate, has had or could
reasonably be expected to have a Material Adverse Effect, and, to the Company's
knowledge, no termination of any such franchises, licenses, permits, consents,
authorizations, regulatory approvals or other approvals, or proceedings to
suspend, limit, revoke or terminate any such franchises, licenses, permits,
consents, authorizations, regulatory approvals or other approvals has been
threatened.

          (b)  Authorization; Enforcement.  The Company has the requisite
corporate power and authority to enter into and perform this Agreement, the
Irrevocable Transfer Agent Instructions (as defined in Section 3.11) and the
Registration Rights Agreement substantially in the form attached hereto as
Exhibit C (the "Registration Rights Agreement") (collectively, the "Transaction
Documents") and to issue and sell the Shares in accordance with the terms of
this Agreement and the Certificate of Designations.  The execution, delivery and
performance of the Transaction Documents and the Certificate of Designations by
the Company and the consummation by it of the transactions contemplated hereby
and thereby have been duly and validly authorized by all necessary corporate
action, and no further consent or authorization of the Company or its Board of
Directors or stockholders is required.  This Agreement has been duly executed
and delivered by the Company. The Registration Rights Agreement and the
Certificate of Designations will have been duly executed and delivered by the
Company at the First Closing.  Each of the Transaction Documents constitutes, or
shall constitute when executed and delivered, a valid and binding obligation of
the Company enforceable against the Company in accordance with its terms, except
as such enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation, conservatorship, receivership or
similar laws relating to, or affecting generally the enforcement of, creditor's
rights and remedies or by other equitable principles of general application.

          (c)  Capitalization.  The authorized capital stock of the Company and
the shares thereof issued and outstanding as of January 27, 2000 are set forth
on Schedule 2.1(c) hereto.  All of the issued and outstanding shares of the
Common Stock, Series A Convertible Preferred Stock, Series C Convertible
Preferred Stock and Series D Convertible Preferred Stock have been duly and
validly authorized and issued and are fully-paid and nonassessable.  Except as
set forth in the 1999 Commission Documents (as defined in Section 2.1(f)
herein), the

                                       3
<PAGE>

Certificate of Incorporation, with any and all amendments thereto, as in effect
on the date hereof (the "Certificate"), or on Schedule 2.1(c) hereto, no shares
of Common Stock or of any series of the Company's preferred stock are entitled
to preemptive rights or registration rights and there are no outstanding
options, warrants, scrip, rights to subscribe to, call or commitments of any
character whatsoever relating to, or securities or rights convertible into, any
shares of capital stock of the Company. Furthermore, except as set forth in this
Agreement and the Registration Rights Agreement, and as set forth in the 1999
Commission Documents, the Certificate or on Schedule 2.1(c), there are no
contracts, commitments, understandings, or arrangements by which the Company is
or may become bound to issue additional shares of the capital stock of the
Company or options, securities or rights convertible into shares of capital
stock of the Company. Except for customary transfer restrictions contained in
agreements entered into by the Company in order to sell restricted securities,
as provided on Schedule 2.1(c) hereto, the Company is not a party to any
agreement granting registration or anti-dilution rights to any person with
respect to any of its equity or debt securities. Except as provided on Schedule
2.1(c), the Company is not a party to any agreement with respect to the voting
or transfer of any shares of the capital stock of the Company. Except as set
forth on Schedule 2.1(c) hereto, the offer and sale of all capital stock,
convertible securities, rights, warrants, or options of the Company issued prior
to the Closing complied with all applicable federal and state securities laws,
and no stockholder has a right of rescission or damages with respect thereto
which would have a Material Adverse Effect. The Company has furnished to each
Purchaser a true, complete and correct copy of the Certificate and the Company's
Bylaws, with any and all amendments thereto, as in effect on the date hereof
(the "Bylaws").

          (d)  Issuance of Shares.  The Preferred Shares to be issued at the
Closing have been duly authorized by all necessary corporate action and, when
paid for or issued in accordance with the terms hereof, the Preferred Shares
shall be validly issued and outstanding, fully paid and nonassessable and
entitled to the rights and preferences set forth in the Certificate of
Designations.  When the Conversion Shares are issued in accordance with the
terms of the Preferred Shares as set forth in the Certificate of Designations,
such shares will be validly issued and outstanding, fully paid and
nonassessable, and the holders shall be entitled to all rights accorded to a
holder of Common Stock.  The Conversion Shares have been duly authorized and
reserved for issuance upon conversion of the Preferred Shares.

          (e)  No Conflicts.  The execution, delivery and performance of the
Transaction Documents by the Company, the performance by the Company of its
obligations under and the execution of the Certificate of Designations and the
consummation by the Company of the transactions contemplated herein and therein
do not and will not (i) violate any provision of the Certificate or Bylaws, (ii)
conflict with, or constitute a default (or an event which 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, any agreement,
mortgage, deed of trust, indenture, note, bond, license, lease agreement,
instrument or obligation to which the Company is a party or by which the
Company's assets are bound, (iii) create or impose a lien, charge or encumbrance
on any property of the Company under any agreement or any commitment to which
the Company is a party or by which the Company is bound or by which any of its
respective properties or assets are bound, or (iv) result in a violation of any
federal, state, local or foreign statute, rule, regulation, order, judgment or
decree (including federal and state securities laws and regulations) applicable
to the Company or any of its subsidiaries or by which any property or

                                       4
<PAGE>

asset of the Company or any of its subsidiaries are bound or affected, except,
in all cases other than violations pursuant to clause (i) above, for such
conflicts, defaults, terminations, amendments, accelerations, cancellations and
violations as would not have, individually or in the aggregate, a Material
Adverse Effect. For the purposes of this Agreement, "Material Adverse Effect"
means any adverse effect on the business, operations, properties, prospects, or
financial condition of the Company and its subsidiaries, taken as a whole, and
which is material to the Company and its subsidiaries, taken as a whole. The
business of the Company and its subsidiaries is not being conducted in violation
of any laws, ordinances or regulations of any governmental entity, except for
possible violations which individually or in the aggregate do not and would not
have a Material Adverse Effect. The Company is not required under federal, state
or local law, rule or regulation to obtain any consent, authorization or order
of, or make any filing or registration with, any court or governmental agency in
order for it to execute, deliver or perform any of its obligations under the
Transaction Documents or the Certificate of Designations, or issue and sell the
Preferred Shares or the Conversion Shares in accordance with the terms hereof or
thereof (other than any filings which may be required to be made by the Company
with the Commission or state securities administrators subsequent to the
Closing, and any registration statement which may be filed pursuant hereto, and
the filing of the Certificate of Designations with the Secretary of State of the
State of Delaware); provided that, for purposes of the representation made in
this sentence, the Company is assuming and relying upon the accuracy of the
relevant representations and agreements of the Purchasers herein.

          (f)  Commission Documents, Financial Statements.  The Common Stock is
registered pursuant to Section 12(g) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and the Company has timely filed all reports,
schedules, forms, statements and other documents required to be filed by it with
the Commission pursuant to the reporting requirements of the Exchange Act,
including materials filed pursuant to Section 13(a) or 15(d) of the Exchange Act
(all of the foregoing, including filings incorporated by reference therein,
being referred to herein as the "Commission Documents").  The Company has
delivered or made available to each of the Purchasers true and complete copies
of the Commission Documents filed with the Commission since December 31, 1998
(the "1999 Commission Documents").  As of their respective dates, the Commission
Documents complied in all material respects with the requirements of the
Exchange Act and the rules and regulations of the Commission promulgated
thereunder and other federal, state and local laws, rules and regulations
applicable to such documents, and, as of their respective dates, none of the
Commission Documents contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading.  The financial statements of the Company
included in the Commission Documents comply as to form in all material respects
with applicable accounting requirements and the published rules and regulations
of the Commission or other applicable rules and regulations with respect
thereto.  Such financial statements have been prepared in accordance with
generally accepted accounting principles ("GAAP") applied on a consistent basis
during the periods involved (except (i) as may be otherwise indicated in such
financial statements or the notes thereto or (ii) in the case of unaudited
interim statements, to the extent they may not include footnotes or may be
condensed or summary statements), and fairly present the financial position of
the Company and its subsidiaries as of the dates thereof and the results of
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end audit adjustments).

          (g)  Subsidiaries.  Schedule 2.1(g) hereto sets forth each subsidiary
of the Company, showing the jurisdiction of its incorporation or organization
and showing the percentage of each applicable person's ownership of the
outstanding stock or other interests of such subsidiary.  Each subsidiary is a
corporation duly incorporated, validly existing and in good standing under the
laws of the state of its incorporation and has the requisite corporate power to
own, lease and operate its properties and assets and to conduct its business as
it is now being conducted.  For the purposes of this Agreement, "subsidiary"
shall mean any corporation or other entity of which at least a majority of the
securities or other ownership interest having ordinary voting power (absolutely
or contingently) for the election of directors or other persons performing
similar functions are at the time owned directly or indirectly by the Company
and/or any of its other subsidiaries.  All of the outstanding shares of capital
stock of each subsidiary have been duly authorized and validly issued, and are
fully paid and nonassessable.  Except as set forth in Schedule 2.1(g), there are
no outstanding preemptive, conversion or other rights, options, warrants or
agreements granted or issued by or binding upon any subsidiary for the purchase
or acquisition of any shares of capital stock of any subsidiary or any other
securities convertible into, exchangeable for or evidencing the rights to
subscribe for any shares of such capital stock.  Neither the Company nor any
subsidiary is subject to any obligation (contingent or otherwise) to repurchase
or otherwise acquire or retire any shares of the capital stock of any subsidiary
or any convertible securities, rights, warrants or options of the type described
in the preceding sentence. Neither the Company nor any subsidiary is party to,
or has any knowledge of, any agreement restricting the voting or transfer of any
shares of the capital stock of any subsidiary.

          (h)  No Material Adverse Change.  Since September 30, 1999, the date
through which the most recent quarterly report of the Company on Form 10-QSB has
been prepared and filed with the Commission, a copy of which is included in the
Commission Documents, the Company has not experienced or suffered any Material
Adverse Effect, except as disclosed on Schedule 2.1(h) hereto.

          (i)  No Undisclosed Liabilities.  Except as disclosed on Schedule
2.1(i) hereto, neither the Company nor any of its subsidiaries has any
liabilities, obligations, claims or losses (whether liquidated or unliquidated,
secured or unsecured, absolute, accrued, contingent or otherwise) other than (i)
those disclosed in the Commission Documents or (ii) those incurred in the
ordinary course of the Company's or its subsidiaries respective businesses since
September 30, 1999 (none of which results from breach of contract, breach of
warranty, tort, infringement claim or other lawsuit) and which, individually or
in the aggregate, do not or would not have a Material Adverse Effect.

          (j)  No Undisclosed Events or Circumstances.  No event or circumstance
has occurred or exists with respect to the Company or its subsidiaries or their
respective businesses, properties, prospects, operations or financial condition,
which, under applicable law, rule or regulation, requires public disclosure or
announcement by the Company but which has not been so publicly announced or
disclosed.

          (k)  Indebtedness.  The 1999 Commission Documents or Schedule 2.1(k)
hereto sets forth as of the date hereof all outstanding secured and unsecured
Indebtedness of the Company or any subsidiary or for which the Company or any
subsidiary has commitments.  For

                                       6
<PAGE>

the purposes of this Agreement, "Indebtedness" shall mean (a) any liabilities
for borrowed money or amounts owed in excess of $25,000 (other than trade
accounts payable incurred in the ordinary course of business), (b) all
guaranties, endorsements and other contingent obligations in respect of
Indebtedness of others, whether or not the same are or should be reflected in
the Company's balance sheet (or the notes thereto), except guaranties by
endorsement of negotiable instruments for deposit or collection or similar
transactions in the ordinary course of business; and (c) the present value of
any lease payments in excess of $25,000 due under leases required to be
capitalized in accordance with GAAP. Neither the Company nor any subsidiary is
in default with respect to any Indebtedness.

          (l)  Title to Assets.  Except as set forth in Schedule 2.1(l), each of
the Company and the subsidiaries has good title to all of its real and personal
property as reflected in the Commission Documents, free of any mortgages,
pledges, charges, liens, security interests or other encumbrances, except which,
individually or in the aggregate, would not have a Material Adverse Effect. All
leases of the Company and each of its subsidiaries are valid and subsisting and
in full force and effect.

          (m)  Actions Pending.  There is no action, suit, claim, investigation
or proceeding pending or, to the knowledge of the Company, threatened against
the Company or any subsidiary which questions the validity of this Agreement or
the transactions contemplated hereby or any action taken or to be taken pursuant
hereto or thereto.  Except as set forth on Schedule 2.1(m) hereto, there is no

subsidiaries has been and is presently being conducted in accordance with all
applicable federal, state and local governmental laws, rules, regulations and
ordinances, except as that, individually or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect.  The Company and each
of its subsidiaries have all franchises, permits, licenses, consents and other
governmental or regulatory authorizations and approvals necessary for the
conduct of its business as now being conducted by it unless the failure to
possess such franchises, permits, licenses, consents and other governmental or
regulatory authorizations and approvals, individually or in the aggregate, could
not reasonably be expected to have a Material Adverse Effect.

          (o)  Taxes.  The Company and each of the subsidiaries has accurately
prepared and filed all Tax Returns required by law to be filed by it; the
Company and each of the subsidiaries has paid all Taxes due and owing and all
additional assessments; and adequate provisions have been made and are reflected
in the financial statements of the Company and the subsidiaries for all current
Taxes and other charges to which the Company or any subsidiary is subject and
which are not currently due and payable.  The Company and each of the
Subsidiaries have withheld and paid over all Taxes which it is obligated to
withhold from amounts paid or owing to any employee, stockholder, creditor or
other third party, except for any failures to so

                                       7

pay as would not have a Material Adverse Effect; neither the Company nor any

Agreement nor the Schedules hereto nor any other documents, certificates, or

<PAGE>

certain circumstances. The Company further acknowledges that its obligation to
issue Conversion Shares upon conversion of the Preferred Shares in accordance
with this Agreement and the Certificate of Designations in accordance with this

dilutive effect that such issuance may have on the ownership interest of other
stockholders of the Company.

Company's and its subsidiaries products and services that record, store, process

error caused by date data that represents or references different centuries or
more than one century (collectively, "Y2K Compliant"). To the knowledge of the
Company, all of the Company's and its subsidiaries material products and
services will lose no functionality with respect to the introduction of records
containing dates falling on or after January 1, 2000. To the knowledge of the

               Section 2.2 Representations and Warranties of the Purchasers.
Each Purchaser hereby makes the following representations and warranties to the
Company with respect solely to itself and not with respect to any other
Purchaser:

               (a)  Organization and Standing of the Purchasers. If the
Purchaser is an entity, the Purchaser is a corporation, partnership, limited
liability company or trust duly incorporated, formed or organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation, formation or organization.

               (b)  Authorization and Power. Each Purchaser has the requisite
power and authority to enter into and perform this Agreement and to purchase the
Preferred Shares being sold to it hereunder. The execution, delivery and
performance of this Agreement and the Registration Rights Agreement by each
Purchaser and the consummation by it of the transactions contemplated hereby and
thereby have been duly authorized by all necessary corporate, partnership,
limited liability or other action (if the Purchaser is an entity), and no
further consent or authorization of such Purchaser or its Board of Directors,
stockholders, partners, managers, members or trustees, as the case may be, is
required. Each of this Agreement and the Registration Rights Agreement has been
duly authorized, executed and delivered by each Purchaser.

               (c)  No Conflicts. The execution, delivery and performance of
this Agreement and the Registration Rights Agreement and the consummation by
each Purchaser of the transactions contemplated hereby and thereby or relating
hereto do not and will not (i) result in a violation of such Purchaser's charter
documents or bylaws or (ii) conflict with, or constitute a default (or an event
which with notice or lapse of time or both would become a default) under, or

                                      16
<PAGE>

give to others any rights of termination, amendment, acceleration or
cancellation of any agreement, indenture or instrument to which such Purchaser
is a party, or result in a violation of any law, rule, or regulation, or any
order, judgment or decree of any court or governmental agency applicable to such
Purchaser or its properties (except for such conflicts, defaults and violations
as would not, individually or in the aggregate, have a material adverse effect
on such Purchaser). No Purchaser is required to obtain any consent,
authorization or order of, or make any filing or registration with, any court or
governmental agency in order for it to execute, deliver or perform any of its
obligations under this Agreement or the Registration Rights Agreement or to
purchase the Preferred Shares in accordance with the terms hereof, provided that
for purposes of the representation made in this sentence, such Purchaser is
assuming and relying upon the accuracy of the relevant representations and
agreements of the Company herein.

          (d)  Acquisition for Investment.  Each Purchaser is purchasing the
Preferred Shares solely for its own account for the purpose of investment and
not with a view to or for sale in connection with distribution.  No Purchaser
has a present intention to sell the Preferred Shares, nor a present arrangement
(whether or not legally binding) or intention to effect any distribution of the
Preferred Shares to or through any person or entity; provided, however, that by
making the representations herein and subject to Section 2.2(f) below, none of
the Purchasers agrees to hold the Preferred Shares for any minimum or other
specific term and each of the Purchasers reserves the right to dispose of the
Preferred Shares at any time in accordance with federal securities laws
applicable to such disposition.  Each Purchaser acknowledges that it is able to
bear the financial risks associated with an investment in the Preferred Shares.

          (e)  Accredited Investors.  Each Purchaser is an "accredited investor"
as defined in Regulation D promulgated under the Securities Act.

          (f)  Rule 144; Listing.  Each Purchaser understands that the Shares
must be held indefinitely unless such Shares are registered under the Securities
Act or an exemption from registration is available.  Each Purchaser acknowledges
that such person is familiar with Rule 144 of the rules and regulations of the
Commission, as amended, promulgated pursuant to the Securities Act ("Rule 144"),
and that such person has been advised that Rule 144 permits resales only under
certain circumstances.  Each Purchaser understands that to the extent that Rule
144 is not available, such person will be unable to sell any Shares without
either registration under the Securities Act or the existence of another
exemption from such registration requirement.  Each Purchaser understands that
the Common Stock is traded on the OTC Bulletin Board and that no assurance can
be given that the Company's Common Stock will qualify for listing or trading on
the Nasdaq Stock Market, or any other relevant exchange, market or system, or
that, if listed or traded thereon in the future, it will continue to qualify for
listing or trading thereon.

          (g)  General.  Each Purchaser understands that the Preferred Shares
are being offered and sold in reliance on a transactional exemption from the
registration requirement of Federal and state securities laws and the Company is
relying upon the truth and accuracy of the representations, warranties,
agreements, acknowledgments and understandings of such Purchaser set forth
herein in order to determine the applicability of such exemptions and the
suitability of such Purchaser to acquire the Preferred Shares.

                                      17
<PAGE>

Purchaser's investment in the Company that have been reasonably requested by
Purchaser. Purchaser acknowledges that the Company is subject to the periodic
reporting requirements of the Exchange Act, and Purchaser has received or
reviewed copies of the Commission Documents.

     Section 3.4  Compliance with Laws.  The Company shall comply, and cause
each subsidiary to comply, with all applicable laws, rules, regulations and

     Section 3.5  Keeping of Records and Books of Account.  The Company shall
keep and cause each subsidiary to keep adequate records and books of account, in

depreciation, depletion, obsolescence, amortization, taxes, bad debts and other
purposes in connection with its business shall be made.

     Section 3.6  Reporting Requirements.  The Company shall furnish the
following to the Purchasers so long as the Purchasers shall be obligated
hereunder to purchase the Preferred Shares or shall beneficially own any
Preferred Shares which represent more than 10% of the total combined voting
power of all voting securities of the Company then outstanding:

          (a)  Quarterly Reports filed with the Commission on Form 10-QSB as
soon as available, and in any event within 45 days after the end of each of the
first three fiscal quarters of the Company or such later date pursuant to an
extension granted by the Commission;

          (b)  Annual Reports filed with the Commission on Form 10-KSB as soon
as available, and in any event within 90 days after the end of each fiscal year
of the Company or such later date pursuant to an extension granted by the
Commission; and

          (c)  Copies of all notices and information, including without
limitation notices and proxy statements in connection with any meetings, that
are provided to holders of shares of Common Stock, contemporaneously with the
delivery of such notices or information to such holders of Common Stock.

     Section 3.7  Amendments.  The Company shall not amend or waive any
provision of the Certificate or Bylaws of the Company or Registration Rights
Agreement in any way that would materially adversely affect any of the rights of
the holders of Preferred Shares, including but not limited to the liquidation
preferences, dividends rights, conversion rights, voting rights or redemption
rights of the holders of the Preferred Shares.

     Section 3.8  Other Agreements.  The Company shall not enter into any
agreement in which the terms of such agreement would materially restrict or
impair the right or ability to perform of the Company or any subsidiary to

outstanding, the Company agrees that it shall not (i) declare or pay any
dividends or make any distributions to any holder(s) of Common Stock or (ii)

option plans.

                                      19

     Section 3.10  Reservation of Shares.  So long as any Preferred Shares
remain outstanding, the Company shall take all action necessary to at all times
have authorized, and reserved for the purpose of issuance, no less than the
aggregate number of shares of Common Stock needed to provide for the issuance of
the Conversion Shares.

     Section 3.11  Transfer Agent Instructions.  The Company shall issue
irrevocable instructions to its transfer agent, and any subsequent transfer
agent, to issue certificates, registered in the name of the Purchasers or their
respective nominee(s), for the Conversion Shares in such amounts as specified
from time to time by the Purchasers to the Company upon conversion of the
Preferred Shares in substantially the form of Exhibit D attached hereto (the
"Irrevocable Transfer Agent Instructions").  Prior to registration of the
Conversion Shares under the Securities Act, all such certificates shall bear the
restrictive legend specified in Section 6.1 of this Agreement.  The Company
warrants that no instruction other than the Irrevocable Transfer Agent
Instructions referred to in this Section 3.11 will be given by the Company to
its transfer agent and that the Shares shall otherwise be freely transferable on
the books and records of the Company as and to the extent provided in this
Agreement and the Registration Rights Agreement.  Nothing in this Section 3.11
shall affect in any way the Purchasers' obligations and agreements set forth in
Section 6.1 to comply with all applicable prospectus delivery requirements, if
any, upon resale of the Shares.  If any Purchaser provides the Company with an
opinion of counsel, in a generally acceptable form, to the effect that a public
sale, assignment or transfer of Shares may be made without registration under
the Securities Act or such Purchaser provides the Company with reasonable
assurances that Shares can be sold pursuant to Rule 144 without any restriction
as to the number of securities acquired as of a particular date that can then be
immediately sold, the Company shall permit the transfer, and, in the case of the
Conversion Shares, promptly instruct its transfer agent to issue one or more
certificates in such name and in such denominations as specified by such
Purchaser and without any restrictive legend.  The Company acknowledges that a
breach by it of its obligations under this Section 3.11 will cause irreparable
harm to the Purchasers by vitiating the intent and purpose of the transactions
contemplated hereby. Accordingly, the Company acknowledges that the remedy at
law for a breach of its obligations under this Section 3.11 will be inadequate
and agrees, in the event of a breach or threatened breach by the Company of the
provisions of this Section 3.11, that the Purchasers shall be entitled, in
addition to all other available remedies, to an order and/or injunction
restraining any breach and requiring immediate issuance and transfer, without
the necessity of showing economic loss and without any bond or other security
being required.

     Section 3.12  FIRPTA.  The Company acknowledges that holders of Preferred
Shares may be foreign persons or may have foreign persons or entities as
partners and that the Company may be required to file or cause to be filed in
the future with the IRS certain statements with its United States income Tax
Returns required under Section 1.897-2(h) of the Treasury Regulations.  The
Company is not a "United States real property holding corporation" within the
meaning of Section 897(c)(2) of the Code and the Company shall use reasonable
efforts consistent with sound business practice to avoid becoming a "United
States real property holding corporation."  Upon the request of any holder of
Preferred Shares, the Company shall provide such holder with a statement that
the Company is not a "United States real property holding corporation" as of the
date specified by the holder (or as of the date of the request if the holder
does not specify a date) and shall send a copy of such statement to the IRS in a
form and manner which identifies the holder and which otherwise satisfies the
requirements of Section 1.897-

                                      20
<PAGE>

2(h)(2) of the Treasury Regulations. In the event the Company in the future
becomes a "United States real property holding corporation," the Company shall
promptly notify each holder in writing of such fact. Thereafter, upon written
request from any holder Preferred Shares, the Company shall provide information,
documentation and assistance to such holder reasonably related to the Company's
status as a "United States real property holding corporation," including but not
limited to (i) an affidavit stating (if true) that the stock held by such holder
is of a class that is regularly traded (as defined by Sections 1.897-1(n) and
1.897-9T of the Treasury Regulations) on an established securities market (as
defined by Section 1.897-1(m) of the Treasury Regulations), and (ii) information
or assistance which would enable such holder to obtain a withholding certificate
permitting a transferee of such holder's stock to avoid or reduce any
withholding obligation such transferee would otherwise have under federal Tax
law.

     Section 3.13   Regulation S.  The Company covenants and agrees that if the
Company fails to (i) file a registration statement within 60 days from the First
Closing Date and/or (ii) register the Conversion Shares within 120 days from the
First Closing Date, under the terms and conditions of the Registration Rights
Agreement attached hereto as Exhibit C, then for so long as any of the Preferred
Shares or Conversion Shares remain outstanding and continue to be "restricted
                                                                   ----------
securities" within the meaning of Rule 144 under the Securities Act, the Company
----------
shall, in order to permit resales of the Preferred Shares or Conversion Shares
pursuant to Regulation S under the Securities Act, (a) continue to file all
material required to be filed pursuant to Section 13(a) or 15(d) of the Exchange
Act, and (b) not knowingly engage in directed selling efforts in connection with
the resale of securities by any Purchaser under Regulation S.

     Section 3.14  Restrictions on Subsequent Financings.  From the First
Closing Date until the date 180 days immediately following such First Closing
Date, the Company covenants and agrees that, without the consent of Purchasers
purchasing at least three-quarters of the Preferred Shares, it will not agree
to, enter into or otherwise accept any subsequent offer or sale to, or exchange
with (or other type of distribution to), any third party (a "Subsequent
Financing"), of Common Stock or any securities convertible or exchangeable into
Common Stock, including debt securities (the "Financing Securities").
Notwithstanding the foregoing, a Subsequent Financing shall not include: (i) any
transaction involving the Company's issuance of any Financing Securities (other
than for cash) (A) as consideration in a merger, acquisition, consolidation or
sale or disposition of stock or assets or (B) in exchange for stock or assets;
(ii) the grant of any Financing Securities under any Company employee benefit
plan, stock option plan, restricted stock plan or stock purchase plan or
agreement for the benefit of the Company's employees, directors or consultants;
(iii) the issuance of Financing Securities pursuant to (x) the options, warrants
or other convertible securities outstanding as of the First Closing Date and (y)
the Second Closing, and specifically listed on the Schedules hereto; or (iv) any
transaction entered into and completed on terms and conditions which contemplate
the exchange, consideration or sale (or other type of distribution or payment,
as applicable) of any Financing Securities at an "effective" price at or above
(A) forty percent (40%) of the closing bid price per share of the Common Stock
on the date of the execution of the definitive agreement to sell such Financing
Securities on the OTC Bulletin Board or any registered

                                      21

national stock exchange or market on which the Common Stock is then listed (or
the then average of the "Pink Sheet" quotes, if the Common Stock is not then
listed on the OTC Bulletin Board or any registered national stock exchange or
market) and (B) $2.50 per share (each of the transactions set forth in (i)-(iv)
of this Section 3.14 being a "Permitted Financing"); provided, however, that
                                                     --------  -------
each such Permitted Financing is not subject to any term or condition which
shall require the Company to file with the Commission a registration statement
in respect of any Financing Securities prior to sixty (60) days after the
Effectiveness Date (as such term is defined in the Registration Rights
Agreement); provided, further, the preceding proviso shall not apply to any
            --------  -------                -------
Permitted Financing pursuant to Section 3.14(ii) which is disclosed in Schedule
2.1(c) hereto under the heading "Registration Rights". The Company will promptly
notify the Purchasers in writing of the terms and conditions of any proposed
Subsequent Financing.

and, if appropriate, securities issued upon conversion thereof, shall be stamped
or otherwise imprinted with a legend substantially in the following form (in
addition to any legend required by applicable state securities or "blue sky"
laws):

     THESE SECURITIES REPRESENTED BY THIS CERTIFICATE (THE
     "SECURITIES") HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
     OF 1933, AS AMENDED (THE "SECURITIES ACT") OR ANY STATE
     SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE
     DISPOSED OF UNLESS REGISTERED UNDER THAT ACT AND UNDER APPLICABLE
     STATE SECURITIES LAWS OR SKYLYNX COMMUNICATIONS, INC. (THE
     "COMPANY") SHALL HAVE RECEIVED AN OPINION OF COUNSEL REASONABLY
     SATISFACTORY TO THE COMPANY THAT REGISTRATION OF SUCH SECURITIES
     UNDER THAT ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE
     SECURITIES LAWS IS NOT REQUIRED.

     The Company agrees to reissue certificates representing the Preferred
Shares or Conversion Shares without the legend set forth above if at such time,
prior to making any transfer of any Preferred Shares or Conversion Shares, such
holder thereof shall give written notice to the Company describing the manner
and terms of such transfer or removal as the Company may reasonably request.
Such proposed transfer or removal will not be effected until: (a) (i) holder has
delivered to the Company a legal opinion from counsel to holder that, in the

                                      25
<PAGE>

opinion of such counsel, the registration of such Preferred Shares or Conversion
Shares under the Securities Act is not required in connection with such proposed
transfer; or (ii) a registration statement under the Securities Act covering
such proposed disposition has been filed by the Company with the Commission and
has become effective under the Securities Act; and (b) the Company is reasonably
satisfied that (i) the registration or qualification of such Preferred Shares or
Conversion Shares under the securities or "blue sky" laws of any state is not
required in connection with such proposed disposition; or (ii) compliance with
applicable state securities or "blue sky" laws has been effected.  The Company
will use its best efforts to respond to any such notice from a holder, or else
effect such transfer or removal, within three (3) days.  In the case of any
proposed transfer under this Section 6, the Company will use reasonable efforts
to comply with any such applicable state securities or "blue sky" laws, but
shall in no event be required, in connection therewith, to qualify to do
business in any state where it is not then qualified or to take any action that
would subject it to tax or to the general service of process in any state where
it is not then subject.  The restrictions on transfer contained in Section 6.1
shall be in addition to, and not by way of limitation of, any other restrictions
on transfer contained in any other section of this Agreement.

Company and the Purchasers purchasing a majority of the Preferred Shares at such
Closing.

     Section 7.2  Other Termination.  This Agreement may be terminated as to
the First Closing by the action of the Board of Directors of the Company or by
the Purchasers purchasing a majority of the Preferred Shares at the First
Closing at any time if the First Closing shall not have been consummated by
February 2, 2000, provided that the reason the First Closing shall not have been
consummated is not the breach of the terminating party's representations,
warranties or covenants hereunder.  This Agreement may be terminated as to the
Second Closing by the action of the Board of Directors of the Company or by the
Purchasers purchasing a majority of the Preferred Shares at the Second Closing
at any time if the Second Closing shall not have been consummated by February
18, 2000, provided that the reason the Second Closing shall not have been
consummated is not the breach of the terminating party's representations,
warranties or covenants hereunder.

     Section 7.3  Effect of Termination.  In the event of termination by the
Company or the Purchasers, written notice thereof shall forthwith be given to
the other party and the transactions contemplated by this Agreement shall be
terminated without further action by either party as to such Closing.  If this
Agreement is terminated as provided in Section 7.1 or 7.2 herein, this Agreement
shall become void and of no further force and effect as to such Closing, and
neither the Company nor the Purchasers as to such Closing shall have any
liability to the other party hereunder, except as otherwise provided in Sections
9.2, 9.9, 9.12 and 9.15.

                                INDEMNIFICATION

     Section 8.1  General Indemnity.  The Company agrees to indemnify and hold
harmless the Purchasers (and their directors, officers, partners, affiliates,
agents, successors and assigns) from and against any and all losses,
liabilities, deficiencies, costs, damages and expenses (including, without
limitation, reasonable attorney's fees, charges and disbursements) incurred by
the Purchasers as a result of any inaccuracy in or breach of the
representations, warranties or covenants made by the Company herein.  The
Purchasers, severally but not jointly, agree to indemnify and hold harmless the
Company and its directors, officers, affiliates, agents, successors and assigns
from and against any and all losses, liabilities, deficiencies, costs, damages
and expenses (including, without limitation, reasonable attorneys fees, charges
and disbursements) incurred by the Company as result of any inaccuracy in or
breach of the representations, warranties or covenants made by the Purchasers
herein.

     Section 8.2  Indemnification Procedure.  Any party entitled to
indemnification under this Article VIII (an "indemnified party") will give
written notice to the indemnifying party of any matters giving rise to a claim
for indemnification; provided, that the failure of any party entitled to
indemnification hereunder to give notice as provided herein shall not relieve
the indemnifying party of its obligations under this Article VIII except to the
extent that the indemnifying party is actually prejudiced by such failure to
give notice.  In case any action, proceeding or claim is brought against an
indemnified party in respect of which indemnification is sought hereunder, the
indemnifying party shall be entitled to participate in and, unless in the
reasonable judgment of the indemnified party a conflict of interest between it
and the indemnifying party may exist with respect of such action, proceeding or
claim, to assume the defense thereof with counsel reasonably satisfactory to the
indemnified party.  In the event that the indemnifying party advises an
indemnified party that it will contest such a claim for indemnification
hereunder, or fails, within thirty (30) days of receipt of any indemnification
notice to notify, in writing, such person of its election to defend, settle or
compromise, at its sole cost and expense, any action, proceeding or claim (or
discontinues its defense at any time after it commences such defense), then the
indemnified party may, at its option, defend, settle or otherwise compromise or
pay such action or claim. In any event, unless and until the indemnifying party
elects in writing to assume and does so assume the defense of any such claim,
proceeding or action, the indemnified party's costs and expenses arising out of
the defense, settlement or compromise of any such action, claim or proceeding
shall be losses subject to indemnification hereunder. The indemnified party
shall cooperate fully with the indemnifying party in connection with any
negotiation or defense of any such action or claim by the indemnifying party and
shall furnish to the indemnifying party all information reasonably available to
the indemnified party which relates to such action or claim. The indemnifying
party shall keep the indemnified party fully apprised at all times as to the
status of the defense or any settlement negotiations with respect thereto. If
the indemnifying party elects to defend any such action or claim, then the
indemnified party shall be entitled to participate in such defense with counsel
of its choice at its sole cost and expense. The indemnifying party shall not be
liable for any settlement of any action, claim or proceeding effected without
its prior written consent. Notwithstanding anything in this Article VIII to the
contrary, the indemnifying party shall not, without the indemnified party's
prior written consent, settle or compromise any claim or consent

                                      27
<PAGE>

to entry of any judgment in respect thereof which imposes any future obligation
on the indemnified party or which does not include, as an unconditional term
thereof, the giving by the claimant or the plaintiff to the indemnified party of
a release from all liability in respect of such claim. The indemnification
required by this Article VIII shall be made by periodic payments of the amount
thereof during the course of investigation or defense, as and when bills are
received or expense, loss, damage or liability is incurred, so long as the
indemnified party irrevocably agrees to refund such moneys if it is ultimately
determined by a court of competent jurisdiction that such party was not entitled
to indemnification. The indemnity agreements contained herein shall be in
addition to (a) any cause of action or similar rights of the indemnified party
against the indemnifying party or others, and (b) any liabilities the
indemnifying party may be subject to pursuant to the law.

other similar taxes and duties levied in connection with issuance of the

Purchasers (i) hereby irrevocably submits to the jurisdiction of the United
States District Court sitting in the State of Delaware for the purposes of any
suit, action or proceeding arising out of or relating to this Agreement or the
Registration Rights Agreement and (ii) hereby waives, and agrees not to assert
in any such suit, action or proceeding, any claim that it is not personally
subject to the jurisdiction of such court, that the suit, action or proceeding
is brought in an inconvenient forum or that the venue of the suit, action or
proceeding is improper. Each of the Company and the Purchasers consents to
process being served in any such suit, action or proceeding by mailing a copy
thereof to such party at the address in effect for notices to it under this

outstanding. No consideration shall be offered or paid to any person to amend or
consent to a waiver or modification of any provision of any of the Transaction
Documents or the Certificate of Designations unless the same consideration is
also offered to all of the parties to the Transaction Documents or holders of
Preferred Shares, as the case may be.

Registration Statement shall be on Form S-3 (except if the Company is not then
eligible to register for resale the Registrable Securities on Form S-3, in which
case such registration shall be on another appropriate form in accordance
herewith). The Company shall (i) not permit any securities other than the
Registrable Securities to be included in the Registration Statement and (ii) use
its best efforts to cause the Registration Statement to be declared effective
under the Securities Act as promptly as possible after filing thereof, but in

Registration Statement is required to be filed because the actual number of
shares of Common Stock into which the Preferred Stock is convertible exceeds the
number of shares of Common Stock initially registered in respect of the
Conversion Shares, the Company shall have thirty (30) days to file such
additional Registration Statement, and the Company shall use its best efforts to
cause such additional Registration Statement to be declared effective by the
Commission as soon as possible, but in no event later than sixty (60) days after
filing.

eligible to register for resale the Registrable Securities on Form S-3, such
registration shall be on another appropriate form in accordance herewith) in
accordance with the method or methods of distribution thereof as specified by
the Holders, and shall use its best efforts to cause the Registration Statement
to become effective and remain effective as provided herein; provided, however,
that not less than five (5) Business Days prior to the filing of the
Registration Statement or any related Prospectus or any amendment or supplement
thereto (including any document that would be incorporated therein by
reference), the Company shall (i) furnish to the Holders and their Special
Counsel copies of all such documents proposed to be filed, which documents
(other than those incorporated by reference) will be subject to the review of
the Holders and their Special Counsel, and (ii) at the request of the Holders,
cause its officers and directors, counsel and independent certified public
accountants to respond to such inquiries as shall be necessary, in the
reasonable opinion of their Special Counsel to the Holders, to conduct a
reasonable investigation within the meaning of the Securities Act.

          The Company shall not file the Registration Statement or any
Prospectus or any amendments or supplements thereto to which the Holders of a
majority of the Registrable Securities or their Special Counsel shall reasonably
object to in writing within three (3) Business Days of their receipt thereof if
such filing may contain information that may result in a misstatement of fact or
an omission of a material fact.

          (b)  (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement as may be
necessary to keep the Registration Statement continuously effective as to the
applicable Registrable Securities for the Effectiveness Period and prepare and
file with the Commission such additional Registration Statements in order to
register for resale under the Securities Act all of the Registrable Securities;
(ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424 (or any similar provisions then in force) promulgated under the
Securities Act; (iii) respond as promptly as practicable to any comments
received from the Commission with respect to the Registration Statement or any
amendment thereto and as promptly as practicable provide the

                                       4
<PAGE>

Holders true and complete copies of all correspondence from and to the
Commission relating to the Registration Statement; and (iv) comply in all
material respects with the provisions of the Securities Act and the Exchange Act
with respect to the disposition of all Registrable Securities covered by the
Registration Statement during the applicable period in accordance with the
intended methods of disposition by the Holders thereof set forth in the
Registration Statement as so amended or in such Prospectus as so supplemented.

          (c)  Notify the Holders and their Special Counsel in writing as
promptly as possible (and, in the case of (i)(A) below, not less than five (5)
Business Days prior to such filing) and (if requested by any such Person)
confirm such notice in writing no later than one (1) Business Day following the
day: (i)(A) when a Prospectus or any Prospectus supplement or post-effective
amendment to the Registration Statement is proposed to be filed; (B) when the
Commission notifies the Company whether there will be a "review" of such
Registration Statement and whenever the Commission comments in writing on such
Registration Statement and (C) with respect to the Registration Statement or any
post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable Securities or the initiation of any Proceedings for that
purpose; (iv) if at any time any of the representations and warranties of the
Company contained in any agreement contemplated hereby ceases to be true and
correct in all material respects; (v) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (vi) of the occurrence of any event that makes any statement made
in the Registration Statement or Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

          (d)  Use its best efforts to avoid the issuance of, or, if issued,
obtain the withdrawal of, (i) any order suspending the effectiveness of the
Registration Statement or (ii) any suspension of the qualification (or exemption
from qualification) of any of the Registrable Securities for sale in any
jurisdiction, at the earliest practicable moment.

          (e)  If requested by the Holders of a majority in interest of the
Registrable Securities, (i) promptly incorporate in a Prospectus supplement or
post-effective amendment to the Registration Statement such information as the
Company reasonably agrees should be included therein and (ii) make all required
filings of such Prospectus supplement or such post-effective amendment as soon
as practicable after the Company has received notification of the matters to be
incorporated in such Prospectus supplement or post-effective amendment.

          (f)  Furnish to any Holders and their Special Counsel, without charge,
one conformed copy of each Registration Statement and each amendment thereto,
including financial

                                       5
<PAGE>

statements and schedules, all documents incorporated or deemed to be
incorporated therein by reference, and all exhibits to the extent requested by
any Holders or their Special Counsel (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the
Commission.

          (g)  Promptly deliver to any Holders and their Special Counsel,
without charge, as many copies of the Prospectus or Prospectuses (including each
form of prospectus) and each amendment or supplement thereto as such Holders or
their Special Counsel may reasonably request; and the Company hereby consents to
the use of such Prospectus and each amendment or supplement thereto by each of
the Holders in connection with the offering and sale of the Registrable
Securities covered by such Prospectus and any amendment or supplement thereto.

          (h)  Prior to any public offering of Registrable Securities, use its
best efforts to register or qualify or cooperate with the Holders and their
Special Counsel in connection with the registration or qualification (or
exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions within the United States as the Holders request in writing, to
keep each such registration or qualification (or exemption therefrom) effective
during the Effectiveness Period and to do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of the
Registrable Securities covered by a Registration Statement; provided, however,
that the Company shall not be required to qualify generally to do business in
any jurisdiction where it is not then so qualified or to take any action that
would subject it to general service of process in any such jurisdiction where it
is not then so subject or subject the Company to any material tax in any such
jurisdiction where it is not then so subject.

          (i)  Cooperate with the Holders to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be sold
pursuant to a Registration Statement, which certificates shall be free of all
restrictive legends, and to enable such Registrable Securities to be in such
denominations and registered in such names as any Holder may request at least
two (2) Business Days prior to any sale of Registrable Securities.

          (j)  Upon the occurrence of any event contemplated by Section
3(c)(vi), as promptly as possible, prepare a supplement or amendment, including
a post-effective amendment, to the Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, and file any other required document so that, as
thereafter delivered, neither the Registration Statement nor such Prospectus
will contain 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,
in the light of the circumstances under which they were made, not misleading.

          (k)  Use its best efforts to cause all Registrable Securities relating
to such Registration Statement to be listed on the OTC Bulletin Board and any
other securities exchange, quotation system, market or over-the-counter bulletin
board, if any, on which similar securities issued by the Company are then listed
as and when required pursuant to the Purchase Agreement.

                                       6
<PAGE>

          (l)  Comply in all material respects with all applicable rules and
regulations of the Commission and make generally available to its security
holders earning statements satisfying the provisions of Section 11(a) of the
Securities Act and Rule 158 not later than 90 days after the end of any 12-month
period (or within such extended period of time as may be permitted by the
Commission for filing the applicable report with the Commission) commencing on
the first day of the first fiscal quarter of the Company after the effective
date of the Registration Statement, which statement shall conform to the
requirements of Rule 158.

          (m)  The Company may require each selling Holder to furnish to the
Company information regarding such Holder and the distribution of such
Registrable Securities as is required by law to be disclosed in the Registration
Statement, and the Company may exclude from registration the Registrable
Securities of any such Holder who unreasonably fails to furnish such information
within a reasonable time after receiving such request.

          If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any similar federal statute then in
force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

          Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(g) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective as contemplated by
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to them in connection with sales of Registrable Securities pursuant
to the Registration Statement.

          Each Holder agrees by its acquisition of such Registrable Securities
that, upon receipt of a notice from the Company of the occurrence of any event
of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v) or
3(c)(vi), such Holder will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until such Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(j), or until it is advised in writing (the "Advice")
by the Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

          (n)  If (i) there is material non-public information regarding the
Company which the Company's Board of Directors (the "Board") reasonably
determines not to be in the Company's best interest to disclose and which the
Company is not otherwise required to disclose, or (ii) there is a significant
business opportunity (including, but not limited to, the acquisition or
disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board reasonably determines not to be in the Company's
best interest to disclose and which the Company would be required to disclose
under the Registration Statement, then the Company may postpone or suspend

                                       7
<PAGE>

filing or effectiveness of a Registration Statement for a period not to exceed
twenty (20) consecutive days, provided that the Company may not postpone or
suspend its obligation under this Section 3(n) for more than forty-five (45)
days in the aggregate during any 12-month period (each, a "Blackout Period");
provided, however, that no such postponement or suspension shall be permitted
for consecutive 20-day periods, arising out of the same set of facts,
circumstances or transactions.

     4.   Registration Expenses.
          ---------------------

     All fees and expenses incident to the performance of or compliance with
this Agreement by the Company shall be borne by the Company whether or not the
Registration Statement is filed or becomes effective and whether or not any
Registrable Securities are sold pursuant to the Registration Statement. The fees
and expenses referred to in the foregoing sentence shall include, without
limitation: (i) all registration and filing fees (including, without limitation,
fees and expenses (A) with respect to filings required to be made with the OTC
Bulletin Board and each other securities exchange or market on which Registrable
Securities are required hereunder to be listed, (B) with respect to filings
required to be made with the Commission, (C) with respect to filings required to
be made under the OTC Bulletin Board and (D) in compliance with state securities
or Blue Sky laws (including, without limitation, fees and disbursements of
Special Counsel to the Holders in connection with Blue Sky qualifications of the
Registrable Securities and determination of the eligibility of the Registrable
Securities for investment under the laws of such jurisdictions), (ii) printing
expenses (including, without limitation, expenses of printing certificates for
Registrable Securities and of printing prospectuses), (iii) messenger, telephone
and delivery expenses, (iv) fees and disbursements of counsel for the Company
and the Special Counsel for the Holders, in the case of the Special Counsel, up
to a maximum of $10,000, (v) Securities Act liability insurance, if the Company
so desires such insurance, and (vi) fees and expenses of all other Persons
retained by the Company in connection with the consummation of the transactions
contemplated by this Agreement, including, without limitation, the Company's
independent public accountants (including the expenses of any comfort letters or
costs associated with the delivery by independent public accountants of a
comfort letter or comfort letters). In addition, the Company shall be
responsible for all of its internal expenses incurred in connection with the
consummation of the transactions contemplated by this Agreement (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing or relisting of the
Registrable Securities on the OTC Bulletin Board or any securities exchange as
required hereunder.

     5.   Indemnification.
          ---------------

          (a)  Indemnification by the Company.  The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents, brokers (including brokers who
offer and sell Registrable Securities as principal as a result of a pledge or
any failure to perform under a margin call of Common Stock), investment advisors
and employees of each of them, each Person who controls such Holder (within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act)
and the officers, directors, agents, investment advisors and employees of each
such controlling Person, to the fullest extent permitted by applicable law, from
and against any and all losses,

                                       8
<PAGE>

claims, damages, liabilities, costs (including, without limitation, costs of
preparation and attorneys' fees) and expenses (collectively, "Losses"), as
incurred, arising out of or relating to any untrue or alleged untrue statement
of a material fact contained in the Registration Statement, any Prospectus or
any form of prospectus or in any amendment or supplement thereto or in any
preliminary prospectus, or arising out of or relating to any omission or alleged
omission of a material fact required to be stated therein or necessary to make
the statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in the light of the circumstances under which they were
made) not misleading, except to the extent, but only to the extent, that such
untrue statements or omissions are based solely upon information regarding such
Holder furnished in writing to the Company by such Holder expressly for use
therein, which information was reasonably relied on by the Company for use
therein or to the extent that such information relates to such Holder or such
Holder's proposed method of distribution of Registrable Securities and was
reviewed and expressly approved in writing by such Holder expressly for use in
the Registration Statement, such Prospectus or such form of prospectus or in any
amendment or supplement thereto. The Company shall notify the Holders promptly
of the institution, threat or assertion of any Proceeding of which the Company
is aware in connection with the transactions contemplated by this Agreement.
Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of an Indemnified Party and shall survive the
transfer of the Registrable Securities by the Holders.

          (b)  Indemnification by Holders.  The Holders shall, severally and not
jointly, indemnify and hold harmless the Company, the directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses, as
incurred, arising solely out of or based solely upon any untrue statement of a
material fact contained in the Registration Statement, any Prospectus, or any
form of prospectus or in any amendment or supplement thereto or in any
preliminary prospectus, or arising solely out of or based solely upon any
omission of a material fact required to be stated therein or necessary to make
the statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in the light of the circumstances under which they were
made) not misleading, to the extent, but only to the extent, that such untrue
statement or omission is contained in any information so furnished in writing by
such Holder to the Company specifically for inclusion in therein and that such
information was reasonably relied on by the Company for use therein or to the
extent that such information relates to such Holder or such Holder's proposed
method of distribution of Registrable Securities and was reviewed and expressly
approved in writing by such Holder expressly for use in the Registration
Statement, such Prospectus or such form of prospectus or in any amendment or
supplement thereto.  Notwithstanding anything to the contrary contained herein,
the Holder shall be liable under this Section 5(b) for only that amount as does
not exceed the net proceeds to such Holder as a result of the sale of
Registrable Securities pursuant to such Registration Statement.

          (c)  Conduct of Indemnification Proceedings.  If any Proceeding shall
be brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party promptly shall notify the Person
from whom indemnity is sought (the "Indemnifying Party) in writing, and the
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to the Indemnified Party and the

                                       9
<PAGE>

payment of all fees and expenses incurred in connection with defense thereof;
provided, that the failure of any Indemnified Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant to
this Agreement, except (and only) to the extent that it shall be finally
determined by a court of competent jurisdiction (which determination is not
subject to appeal or further review) that such failure shall have proximately
and materially adversely prejudiced the Indemnifying Party.

          An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
or Parties unless:  (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party).  The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld.  No Indemnifying Party shall,
without the prior written consent of the Indemnified Party, effect any
settlement of any pending Proceeding in respect of which any Indemnified Party
is a party, unless such settlement includes an unconditional release of such
Indemnified Party from all liability on claims that are the subject matter of
such Proceeding.

          All fees and expenses of the Indemnified Party (including reasonable
fees and expenses to the extent incurred in connection with investigating or
preparing to defend such Proceeding in a manner not inconsistent with this
Section) shall be paid to the Indemnified Party, as incurred, within ten (10)
Business Days of written notice thereof to the Indemnifying Party (regardless of
whether it is ultimately determined that an Indemnified Party is not entitled to
indemnification hereunder; provided, that the Indemnifying Party may require
such Indemnified Party to undertake to reimburse all such fees and expenses to
the extent it is finally judicially determined that such Indemnified Party is
not entitled to indemnification hereunder).

          (d)  Contribution.  If a claim for indemnification under Section 5(a)
or 5(b) is unavailable to an Indemnified Party because of a failure or refusal
of a governmental authority to enforce such indemnification in accordance with
its terms (by reason of public policy or otherwise), then each Indemnifying
Party, in lieu of indemnifying such Indemnified Party, shall contribute to the
amount paid or payable by such Indemnified Party as a result of such Losses, in
such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party and Indemnified Party in connection with the actions,
statements or omissions that resulted in such Losses as well as any other
relevant equitable considerations.  The relative fault of such Indemnifying
Party and Indemnified Party shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission of a material fact,
has been taken or made by, or

                                       10
<PAGE>

relates to information supplied by, such Indemnifying, Party or Indemnified
Party, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such action, statement or omission. The amount
paid or payable by a party as a result of any Losses shall be deemed to include,
subject to the limitations set forth in Section 5(c), any reasonable attorneys'
or other reasonable fees or expenses incurred by such party in connection with
any Proceeding to the extent such party would have been indemnified for such
fees or expenses if the indemnification provided for in this Section was
available to such party in accordance with its terms. Notwithstanding anything
to the contrary contained herein, such Holder shall be liable or required to
contribute under this Section 5(c) for only that amount as does not exceed the
net proceeds to such Holder as a result of the sale of Registrable Securities
pursuant to such Registration Statement.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

          The indemnity and contribution agreements contained in this Section
are in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

     6.   Rule 144 and Piggyback Registration.
          -----------------------------------

     (a)  As long as any Holder owns Preferred Stock or Conversion Securities,
the Company covenants to timely file (or obtain extensions in respect thereof
and file within the applicable grace period) all reports required to be filed by
the Company after the date hereof pursuant to Section 13(a) or 15(d) of the
Exchange Act and to promptly furnish the Holders with true and complete copies
of all such filings.  As long as any Holder owns Preferred Stock or Conversion
Shares, if the Company is not required to file reports pursuant to Section 13(a)
or 15(d) of the Exchange Act, it will prepare and furnish to the Holders and
make publicly available in accordance with Rule 144(c) promulgated under the
Securities Act annual and quarterly financial statements, together with a
discussion and analysis of such financial statements in form and substance
substantially similar to those that would otherwise be required to be included
in reports required by Section 13(a) or 15(d) of the Exchange Act, as well as
any other information required thereby, in the time period that such filings
would have been required to have been made under the Exchange Act.  The Company
further covenants that it will take such further action as any Holder may
reasonably request, all to the extent required from time to time to enable such
Person to sell Conversion Shares without registration under the Securities Act
within the limitation of the exemptions provided by Rule 144 promulgated under
the Securities Act.  Upon the request of any Holder, the Company shall deliver
to such Holder a written certification of a duly authorized officer as to
whether it has complied with such requirements.

     (b)  If at any time when there is not an effective Registration Statement
covering Conversion Shares, the Company shall determine to prepare and file with
the Commission a registration statement relating to an offering for its own
account or the account of others under the Securities Act of any of its equity
securities, other than: (1) on Form S-4 or Form S-8 (each

                                       11
<PAGE>

as promulgated under the Securities Act) or its then equivalents relating to
equity securities to be issued solely in connection with any acquisition of any
entity or business or equity securities issuable in connection with stock option
or other employee benefit plans; or (2) the Company's amendment or successor
registration statement to the Company's Registration Statement on Form SB-2
Registration No. 333-83705 to be filed in connection with the reincorporation of
the Company in the State of Delaware, the Company shall send to each Holder of
Registrable Securities written notice of such determination and the Company will
cause the registration under the Securities Act of all Registrable Securities
(unless within thirty (30) days after receipt of such notice, any such Holder
shall notify the Company in writing that it elects to have less than all of its
Registrable Securities intended to be disposed of by such Holder included in
such registration) to the extent requisite to permit the disposition of the
Registrable Securities so to be registered, provided that if at any time after
giving written notice of its intention to register any securities and prior to
the effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason not to register or to
delay registration of such securities, the Company may, at its election, give
written notice of such determination to such Holder and, thereupon, (i) in the
case of a determination not to register, shall be relieved of its obligation to
register any Registrable Securities in connection with such registration (but
not from its obligation to pay expenses in accordance with Section 4 hereof),
and (ii) in the case of a determination to delay registering, shall be permitted
to delay registering any Registrable Securities being registered pursuant to
this Section 6(b) for the same period as the delay in registering such other
securities. The Company shall include in such registration statement all or any
part of such Registrable Securities such Holder requests to be registered;
provided, however, that the Company shall not be required to register any
Registrable Securities pursuant to this Section 6(b) that are eligible for sale
pursuant to Rule 144(k) of the Securities Act. In the case of an underwritten
public offering, if the managing underwriter(s) or underwriter(s) should
reasonably object to the inclusion of the Registrable Securities in such
registration statement, then if the Company after consultation with the managing
underwriter should reasonably determine that the inclusion of such Registrable
Securities would materially adversely affect the offering contemplated in such
registration statement, and based on such determination recommends inclusion in
such registration statement of fewer or none of the Registrable Securities of
the Holders, then (x) the number of Registrable Securities of the Holders
included in such registration statement shall be reduced pro-rata among such
Holders (based upon the number of Registrable Securities requested to be
included in the registration), if the Company after consultation with the
underwriter(s) recommends the inclusion of fewer Registrable Securities, or (y)
none of the Registrable Securities of the Holders shall be included in such
registration statement, if the Company after consultation with the
underwriter(s) recommends the inclusion of none of such Registrable Securities;
provided, however, that if securities are being offered for the account of other
persons or entities as well as the Company, such reduction shall not represent a
greater fraction of the number of Registrable Securities intended to be offered
by the Holders than the fraction of similar reductions imposed on such other
persons or entities (other than the Company).

     7.   Miscellaneous.
          -------------

          (a)  Remedies. In the event of a breach by the Company, on the one
hand, or by a Holder, on the other hand, of any of their respective obligations
under this Agreement, each Holder or the Company, as the case may be, in
addition to being entitled to exercise all rights

                                       12
<PAGE>

granted by law and under this Agreement, including recovery of damages, will be
entitled to specific performance of its respective rights under this Agreement.
The Company and the Holders agree that monetary damages would not provide
adequate compensation for any losses incurred by reason of a breach by it of any
of the provisions of this Agreement and hereby further agree that, in the event
of any action for specific performance in respect of such breach, it shall waive
the defense that a remedy at law would be adequate.

          (b)  No Inconsistent Agreements.  Except as set forth in the
Registration Rights Agreement, dated as of January 18, 1999, by and among the
Company and purchasers of its Series B Convertible Preferred Stock, the
Registration Rights Agreement, dated as of April 16, 1999, by and among the
Company and purchasers of its Series D Convertible Preferred Stock, and the
Registration Rights Agreement, dated as of May 6, 1999, by and among the Company
and purchasers of its Series E Convertible Preferred Stock (the "Prior
Registration Rights Agreements"), neither the Company nor any of its
subsidiaries is, as of the date hereof, a party to, nor shall the Company or any
of its subsidiaries, on or after the date of this Agreement, enter into, any
agreement with respect to its securities that is inconsistent with the rights
granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof.  Without limiting the generality of the foregoing, without
the written consent of the Holders of at least three-quarters of the then
outstanding Registrable Securities, the Company shall not grant to any Person
the right to request the Company to register any securities of the Company under
the Securities Act unless the rights so granted are not prior to and are not
otherwise in conflict with the provisions of this Agreement.

          (c)  No Piggyback on Registrations.  Except as set forth in the Prior
Registration Rights Agreements, neither the Company nor any of its security
holders (other than the Holders in such capacity pursuant hereto) may include
securities of the Company in the Registration Statement, and the Company shall
not after the date hereof enter into any agreement providing such right to any
of its security holders, unless the right so granted is subject in all respects
to the prior rights in full of the Holders set forth herein, and is not
otherwise in conflict with the provisions of this Agreement.

          (d)  Failure to File Registration Statement and Other Events. The
Company and the Purchasers agree that the Holders will suffer damages if the
Registration Statement is not filed on or prior to the Filing Date and not
declared effective by the Commission on or prior to the Effectiveness Date and
maintained in the manner contemplated herein during the Effectiveness Period or
if certain other events occur. The Company and the Holders further agree that it
would not be feasible to ascertain the extent of such damages with precision.
Accordingly, if (i) the Registration Statement is not filed on or prior to the
Filing Date, or is not declared effective by the Commission on or prior to the
Effectiveness Date (or in the event an additional Registration Statement to be
filed because the actual number of shares of Common Stock into which the
Preferred Stock is convertible exceeds the number of shares of Common Stock
initially registered is not filed and declared effective within the time periods
set forth in Section 2(a)), or (ii) the Company fails to file with the
Commission a request for acceleration in accordance with Rule 12d1-2 promulgated
under the Exchange Act within five (5) Business Days of the date that the
Company is notified (orally or in writing, whichever is earlier) by the
Commission that a Registration Statement will not be "reviewed," or not subject
to further review, or (iii) the Registration Statement is filed with and
declared effective by the Commission

                                       13
<PAGE>

but thereafter ceases to be effective as to all Registrable Securities at any
time prior to the expiration of the Effectiveness Period, without being
succeeded immediately by a subsequent Registration Statement filed with and
declared effective by the Commission, or (iv) trading in the Common Stock shall
be suspended or if the Common Stock is delisted from the OTC Bulletin Board for
any reason for more than ten (10) Business Days in the aggregate, or (v) the
Company breaches in a material respect (x) any covenant or other material term
or condition to this Agreement, (y) Section 5(b)(ii) or (v) or Section 5(k) of
the Certificate of Designation or (z) Section 3.2, 3.7, 3.8, 3.10, 3.11, 3.13 or
3.14 of the Purchase Agreement, and such breach continues for a period of thirty
(30) days after written notice thereof to the Company, or (vi) the Company has
breached Section 3(n) of this Agreement (any such failure or breach of this
Section 7(e)((i)-(vi) being referred to as an "Event"), the Company shall pay in
                                               -----
cash as liquidated damages for such failure and not as a penalty to each Holder
an amount equal to one percent (1%) of such Holder's pro rata share of the
purchase price paid by all Holders for all shares of the Preferred Stock
purchased and then outstanding pursuant to the Purchase Agreement for the
initial thirty (30) day period until the applicable Event has been cured, which
shall be pro rated for such periods less than thirty (30) days, and two percent
(2%) of such Holder's pro rata share for each thirty (30) day period thereafter
until the applicable Event has been cured (which shall be also pro rated, as
aforesaid) (the "Periodic Amount"). Payments to be made pursuant to this Section
                 ---------------
7(e) shall be due and payable immediately upon demand in immediately available
funds. The parties agree that the Periodic Amount represents a reasonable
estimate on the part of the parties, as of the date of this Agreement, of the
amount of damages that may be incurred by the Holders if the Registration
Statement is not filed on or prior to the Filing Date or has not been declared
effective by the Commission on or prior to the Effectiveness Date and maintained
in the manner contemplated herein during the Effectiveness Period or if any
other Event as described herein has occurred and not been cured.

          (e)  Specific Enforcement, Consent to Jurisdiction.

          (i)  The Company and the Purchasers acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement or the Purchase Agreement were not performed in accordance with their
specific terms or were otherwise breached.  It is accordingly agreed that the
parties shall be entitled to an injunction or injunctions to prevent or cure
breaches of the provisions of this Agreement or the Purchase Agreement and to
enforce specifically the terms and provisions hereof or thereof, this being in
addition to any other remedy to which any of them may be entitled by law or
equity.

          (ii) Each of the Company and each of the Purchasers (i) hereby
irrevocably submits to the jurisdiction of the United States District Court
sitting in the State of Delaware for the purposes of any suit, action or
proceeding arising out of or relating to this Agreement or the Purchase
Agreement and (ii) hereby waives, and agrees not to assert in any such suit,
action or proceeding, any claim that it is not personally subject to the
jurisdiction of such court, that the suit, action or proceeding is brought in an
inconvenient forum or that the venue of the suit, action or proceeding is
improper. Each of the Company and each of the Purchasers consents to process
being served in any such suit, action or proceeding by mailing a copy thereof to
such party at the address in effect for notices to it under this Agreement and
agrees that such service shall constitute good and sufficient service of process
and notice thereof. Nothing in this Section 7(e) shall affect or limit any right
to serve process in any other manner permitted by law.
