                                   ARTICLE II

                                CONVERSION RIGHTS

         The Holder shall have the right to convert the principal amount and
interest due under this Note into shares of the Borrower's Common Stock as set
forth below.

         2.1. Conversion into the Borrower's Common Stock.
              -------------------------------------------

         (a) The Holder shall have the right from and after the issuance of this
Note and then at any time until this Note is fully paid, to convert any
outstanding and unpaid principal portion of this Note, and at the Holder's
election, the interest accrued on the Note, (the date of giving of such notice
of conversion being a "Conversion Date") into fully paid and nonassessable
shares of common stock of the Borrower as such stock exists on the date of
issuance of this Note, or any shares of capital stock of the Borrower into which
such stock shall hereafter be changed or reclassified (the "Common Stock") at
the conversion price as defined in Section 2.1(b) hereof (the "Conversion
Price"), determined as provided herein. Upon delivery to the Borrower of a
Notice of Conversion as described in Section 8 of the Securities Purchase
Agreement entered into between the Borrower and certain persons who are
signatories thereto, including the Holder, relating to this Note (the "Purchase
Agreement") of the Holder's written request for conversion, the Borrower shall
issue and deliver to the Holder within four business days beginning on the day
following the date that the Company receives the Notice of Conversion that
number of shares of Common Stock for the portion of the Note converted in
accordance with the foregoing. At the election of the Holder, the Borrower will
deliver accrued but unpaid interest on the Note through the Conversion Date
directly to the Holder on or before the Delivery Date (as defined in the
Purchase Agreement). The number of shares of Common Stock to be issued upon each
conversion of this Note shall be determined by dividing that portion of the
principal of the Note to be converted and interest, if any, by the Conversion
Price.

         (b) Subject to adjustment as provided in Section 2.1(c) hereof, the
Conversion Price per share shall be the lower of (i) one hundred and five
percent (105%) of the closing price for the Common Stock on the NASD OTC
Bulletin Board, NASDAQ SmallCap Market, NASDAQ National Market System, American
Stock Exchange, or New York Stock Exchange (whichever of the foregoing is at the
time the principal trading exchange or market for the Common Stock, the
"Principal Market"), or if not then trading on a Principal Market, such other
principal market or exchange where the Common Stock is listed or traded, on the
Closing Date (as defined in the Purchase Agreement) in connection with which
this Note is issued ("Maximum Base Price"); or (ii) eighty percent (80%) of the
five lowest "VWAP" for the Common Stock on the Principal Market, or on any
securities exchange or other securities market on which the Common Stock is then
being listed or traded, for the thirty (30) trading days prior to but not
including the Conversion Date. "VWAP" shall mean the daily volume weighted
average prices of the Common Stock on the Principal Market as reported by
Bloomberg, L.P. using the AQR function.

                                       2

<PAGE>

     (c) The Maximum Base Price described in Section 2.1(b)(i) above and number
and kind of shares or other securities to be issued upon conversion determined
pursuant to Section 2.1(a) and 2.1(b), shall be subject to adjustment from time
to time upon the happening of certain events while this conversion right remains
outstanding, as follows:

          A. Merger, Sale of Assets, etc. If the Borrower at any time shall
             ---------------------------
consolidate with or merge into or sell or convey all or substantially all its
assets to any other corporation, this Note, as to the unpaid principal portion
thereof and accrued interest thereon, shall thereafter be deemed to evidence the
right to purchase such number and kind of shares or other securities and
property as would have been issuable or distributable on account of such
consolidation, merger, sale or conveyance, upon or with respect to the
securities subject to the conversion or purchase right immediately prior to such
consolidation, merger, sale or conveyance. The foregoing provision shall
similarly apply to successive transactions of a similar nature by any such
successor or purchaser. Without limiting the generality of the foregoing, the
anti-dilution provisions of this Section shall apply to such securities of such
successor or purchaser after any such consolidation, merger, sale or conveyance.

          B. Reclassification, etc. If the Borrower at any time shall, by
             ---------------------
reclassification or otherwise, change the Common Stock into the same or a
different number of securities of any class or classes, this Note, as to the
unpaid principal portion thereof and accrued interest thereon, shall thereafter
be deemed to evidence the right to purchase an adjusted number of such
securities and kind of securities as would have been issuable as the result of
such change with respect to the Common Stock immediately prior to such
reclassification or other change.

          C. Stock Splits, Combinations and Dividends. If the shares of Common
             ----------------------------------------
Stock are subdivided or combined into a greater or smaller number of shares of
Common Stock, or if a dividend is paid on the Common Stock in shares of Common
Stock, the Conversion Price shall be proportionately reduced in case of
subdivision of shares or stock dividend or proportionately increased in the case
of combination of shares, in each such case by the ratio which the total number
of shares of Common Stock outstanding immediately after such event bears to the
total number of shares of Common Stock outstanding immediately prior to such
event.

          D. Share Issuance. Subject to the provisions of this Section, if the
             --------------
Borrower at any time shall issue any shares of Common Stock prior to the
conversion of the entire principal amount of the Note (otherwise than as: (i)
provided in Sections 2.1(c)A, 2.1(c)B or 2.1(c)C or this subparagraph D; or (ii)
pursuant to options, warrants, or other obligations to issue shares, outstanding
on the date hereof as set forth in the Schedules to the Purchase Agreement; ((i)
and (ii) above, are hereinafter referred to as the "Existing Option
Obligations") for a consideration less than the Conversion Price that would be
in effect at the time of such issue, then, and thereafter successively upon each
such issue, the Conversion Price shall be reduced as follows: (i) the number of
shares of Common Stock outstanding immediately prior to such issue shall be
multiplied by the Conversion Price in effect at the time of such issue and the
product shall be added to the aggregate consideration, if any, received by the
Borrower upon such issue of additional shares of

                                       3

<PAGE>

Common Stock; and (ii) the sum so obtained shall be divided by the number of
shares of Common Stock outstanding immediately after such issue. The resulting
quotient shall be the adjusted conversion price. Except for the Existing Option
Obligations and options that may be issued under any employee incentive stock
option and/or any qualified stock option plan adopted by the Borrower, or
securities issued in connection with equipment leasing financings or other
related transactions, for purposes of this adjustment, the issuance of any
security of the Borrower carrying the right to convert such security into shares
of Common Stock or of any warrant, right or option to purchase Common Stock
shall result in an adjustment to the Conversion Price upon the issuance of
shares of Common Stock upon exercise of such conversion or purchase rights.

     (d) During the period the conversion right exists, the Borrower will
reserve from its authorized and unissued Common Stock a sufficient number of
shares to provide for the issuance of Common Stock upon the full conversion of
this Note. The Borrower represents that upon issuance, such shares will be duly
and validly issued, fully paid and non-assessable. The Borrower agrees that its
issuance of this Note shall constitute full authority to its officers, agents,
and transfer agents who are charged with the duty of executing and issuing stock
certificates to execute and issue the necessary certificates for shares of
Common Stock upon the conversion of this Note.

     2.2 Method of Conversion. This Note may be converted by the Holder in whole
         --------------------
or in part as described in Section 2.1(a) hereof and the Purchase Agreement.
Upon partial conversion of this Note, a new Note containing the same date and
provisions of this Note shall, at the request of the Holder, be issued by the
Borrower to the Holder for the principal balance of this Note and interest which
shall not have been converted or paid.

                                   ARTICLE III

                                EVENT OF DEFAULT

     The occurrence of any of the following events of default ("Event of
Default") shall, at the option of the Holder hereof, make all sums of principal
and interest then remaining unpaid hereon and all other amounts payable
hereunder immediately due and payable, except as set forth below:

     3.1 Failure to Pay Principal or Interest. The Borrower fails to pay any
         ------------------------------------
installment of principal or interest hereon or on any other promissory note
issued pursuant to the Purchase Agreement, when due and such failure continues
for a period of five (5) days after the due date.

     3.2 Breach of Covenant. The Borrower breaches any material covenant or
         ------------------
other term or condition of this Note in any material respect and such breach, if
subject to cure, continues for a period of seven (7) days after written notice
to the Borrower from the Holder.

------------

     4.10  Amendment to Bylaws.  Within five (5) Business Days of the First
           -------------------
Closing, the Company will cause its Bylaws to be amended to require the
unanimous consent and approval of all members of the Board of Directors of the
Company in attendance at a duly convened meeting of the Board of Directors prior
to (i) incurring indebtedness for borrowed money, if such borrowing would result
in the Company's then outstanding liability for all such then outstanding
borrowings to exceed $1 million; (ii) taking any action which results in the
redemption of any of the Company's outstanding shares of Common Stock or
Preferred Stock; (iii) approving any merger, other corporate reorganization,

any of the provisions of the Company's Articles of Incorporation or Bylaws.

     The Company shall use its best efforts to see that the representations and

percent (25%) or more of the Company's Common Stock.

     4.11  Election to the Board of Directors.  Within five (5) Business Days of
           ----------------------------------

Stock, use its best efforts to see that two such nominees of the Purchaser are
elected to the Company's Board of Directors.

     4.12  Adjustment in Number of Shares.  In the event that the terms of any
           ------------------------------
funding by the Company during the period between the First Closing and the
earliest to occur of (i) the second anniversary of the First Closing, (ii) the
raising by the Company of additional proceeds aggregating at least an additional
$7.5 million or (iii) the Closing Bid Price  (as defined in the Warrant) has
exceeded $3.00 for thirty (30) consecutive Trading Days following the Effective
Date (as defined in the Registration Rights Agreement) is at an effective
offering price ("Effective Price") of less than $1.00 per share of Common Stock,
                 ---------------
the Company shall issue to Purchaser such number of additional shares of the
Company's Common Stock as is necessary to cause the value of the total number of
shares of the Company's Common Stock, including such additional shares,
delivered in connection with the purchase of the Common Stock to be equal to the
total purchase price

                                      12
<PAGE>

paid for the Common Stock by the Purchaser, less the amount (if any) received by
the Purchaser in connection with the sale or other transfer of Common Stock at a
price in excess of $1.00 per share, the value of the Common Stock being based on
the Effective Price. If the securities sold in such offering are securities of
the Company which are convertible into the Company's Common Stock and no other
securities are sold with such convertible securities and the convertible
securities do not provide for the payment of interest or dividends, other than
dividends payable equally to all of the Company's securities holders, the
conversion price for the convertible securities shall be deemed to be the
Effective Price. If the funding includes securities other than the Company's
Common Stock or securities convertible into the Company's Common Stock, which
convertible securities do not entitle the holders thereof to any interest or
dividend payments other than those available to all of the Company's securities
holders, the company and Purchaser shall negotiate in good faith to determine
the Effective Price. If the parties cannot agree on the Effective Price within
thirty (30) days of the closing of the funding, the Company and Purchaser shall
each indicate in writing what they believe to be the Effective Price and shall
submit the determination of the effective Price to arbitration in Denver,
Colorado in accordance with the rules of the American Arbitration Association.
The determination of the Effective Price pursuant to such arbitration shall be
binding on the parties. The party whose stated Effective Price is furthest from
the price established in arbitration shall pay the cost of such arbitration. If
the difference between the stated Effective Price for each of the parties is
equal, the cost of the arbitration shall be borne equally by the parties.

     4.13 Intentional Acts or Omissions. The Company shall not intentionally
          -----------------------------
perform any act which if performed, or intentionally omit to perform any act
which, if omitted to be performed, would prevent or excuse the performance of
this Agreement or any of the transactions contemplated hereby.

made by or on behalf

                                      16
<PAGE>

of the party seeking to rely thereon. In the event that any provision of this
Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable or void, this Agreement shall continue in full force and
effect without said provision; provided that in such case the parties shall
negotiate in good faith to replace such provision with a new provision which is
not illegal, unenforceable or void, as long as such new provision does not
materially change the economic benefits of this Agreement to the parties. The
Company agrees that it will indemnify and hold harmless the Purchaser for any
loss, claim, liability, damage or expense, as incurred by such Purchaser,
arising out of or in connection with (a) a breach by the Company of any
representation, warranty or agreement made herein or in any other Transaction
Document, (b) any cause of action, suit or claim brought or made against such
indemnitee (other than directly by the Company solely for breach of this
Agreement, the Warrants or the Registration Rights Agreement by the indemnitee
or by governmental or regulatory authorities), and arising out of or resulting
from (whether in whole or in part) the execution, delivery, performance or
enforcement of this Agreement or any other Transaction Document), any
transaction financed or to be financed in whole or in part, directly or
indirectly, with the proceeds of the issuance of the Securities or the status of
the Purchaser as an investor in the Company, except to the extent that such
actual loss or damage results from a breach by such indemnitee of this
Agreement, the Warrants or the Registration Rights Agreement or from a
Purchaser's violation of law, or (c) any characterization concerning any
Transaction Document other than as expressly provided herein or therein, as the
case may be, including, without limitation, any characterization that the
exercise of Purchaser rights and remedies under any of the Transaction Documents
(or through a combination) results in a Purchaser acting (or agreeing to act)
other than independently and on its own behalf. The right to indemnification
shall include the right to advancement of expenses as they are incurred.

     6.2  Successors and Assigns. The terms and conditions of this Agreement
          ----------------------
shall inure to the benefit of and be binding upon the respective successors and
permitted assigns of the parties. Nothing in this Agreement, express or implied,
is intended to confer upon any party other than the parties hereto or their
respective successors and permitted assigns any rights, remedies, obligations or
liabilities under or by reason of this Agreement, except as expressly provided
in this Agreement. The Purchaser may assign its rights and obligations
hereunder, in connection with any private sale or transfer of Securities
pursuant to Section 2.4, as long as, as a condition precedent to such transfer,
the transferee executes an acknowledgment agreeing to be bound by the applicable
provisions of this Agreement, in which case the term "Purchaser" shall be deemed
to refer to such transferee as though such transferee were an original signatory
hereto. The Company may not assign it rights or obligations under this Agreement
except as may be specifically provided by this Agreement or the other
Transaction Documents.

     6.3  No Reliance. Each party acknowledges that (i) it has such knowledge in
          -----------
business and financial matters as to be fully capable of evaluating this
Agreement, the other Transaction Documents and the transactions contemplated
hereby and thereby, (ii) it is not relying on any advice or representation of
the other party in connection with entering into this Agreement, the other
Transaction Documents or such transactions

                                      17
<PAGE>

(other than the representations made in this Agreement or the other Transaction
Documents), (iii) it has not received from such party any assurance or guarantee
as to the merits (whether legal, regulatory, tax, financial or otherwise) of
entering into this Agreement or the other Transaction Documents or the
performance of its obligations hereunder and thereunder, and (iv) it has
consulted with its own legal, regulatory, tax, business, investment, financial
and accounting advisors to the extent that it has deemed necessary, and has
entered into this Agreement and the other Transaction Documents based on its own
independent judgment and on the advice of its advisors as it has deemed
necessary, and not on any view (whether written or oral) expressed by such
party.

     6.4  Injunctive Relief. The Company acknowledges that a breach by it of its
          -----------------
obligations hereunder will cause irreparable harm to the Purchaser and that the
remedy or remedies at law for any such breach will be inadequate and agrees, in
the event of any such breach, in addition to all other available remedies, to an
injunction restraining any breach and requiring immediate and specific
performance of such obligations without the necessity of showing economic loss.

     6.5  Governing Law; Jurisdiction. This Agreement shall be governed by and
          -------------  ------------
construed under the laws of the State of Colorado without regard to the conflict
of laws provisions thereof. Each party hereby irrevocably submits to the non-
exclusive jurisdiction of the state and federal courts sitting in the City of
Denver, Colorado for the adjudication of any dispute hereunder or under any
Transaction Document or in connection herewith or therewith or with any
transaction contemplated hereby or thereby or discussed herein or therein, and
hereby irrevocably waives, and agrees not to assert in any suit, action or
proceeding, any claim that it is not personally subject to the jurisdiction of
any such court, that such suit, action or proceeding is brought in an
inconvenient forum or that the venue of such suit, action or proceeding is
improper. Each party hereby irrevocably waives personal service of process and
consents to process being served in any such suit, action or proceeding by
mailing a copy thereof (certified or registered mail, return receipt requested)
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 contained herein shall be deemed to limit in
any way any right to serve process in any manner permitted by law.

     6.6  Counterparts. This Agreement may be executed in any number of
          ------------
counterparts, each of which shall be deemed an original, and all of which
together shall constitute one and the same instrument.

     6.7  Headings; Drafting. The headings used in this Agreement are used for
          --------  --------
convenience only and are not to be considered in construing or interpreting this
Agreement. The parties shall be deemed to have participated jointly in the
drafting of this Agreement and the other Transaction Documents, and no provision
hereof or thereof shall be construed against any party as the drafter thereof.

     6.8  Notices. Any notice, demand or request required or permitted to be
          -------
given by any party to any other party pursuant to the terms of this Agreement
shall be in writing

used herein and not otherwise defined shall have the respective meanings set
forth in the Securities Purchase Agreement, including the exhibits thereto.

     1. Exercise.

          (a)  Right to Exercise; Exercise Price. The Holder shall have the
               -----------------  --------------
right to exercise this Warrant at any time and from time to time during the
period beginning on the Issue Date and ending on the Expiration Date as to all
or any part of the shares of Common Stock covered hereby (the "Warrant Shares").
                                                               --------------
The "Exercise Price" payable by the Holder in connection with the exercise of
this Warrant shall initially be $1.00 per share, subject to adjustment for the
events specified in Section 6 below.

          (b)  Exercise Notice. In order to exercise this Warrant, the Holder
               ---------------
shall send by facsimile transmission, at any time prior to 5:00 p.m., mountain
time, on the

                                       21
<PAGE>

Business Day (as defined below) on which the Holder wishes to effect such
exercise (the "Exercise Date"), to the Company a copy of the notice of exercise
               -------------
in the form attached hereto as Exhibit A (the "Exercise Notice") stating the
                                               ---------------
number of Warrant Shares as to which such exercise applies and the calculation
therefor. As used herein, "Business Day" shall mean any day on which the New
                           ------------
York Stock Exchange (the "NYSE") and commercial banks in the city of New York
                          ----
are open for business. The Holder shall thereafter deliver to the Company the
original Exercise Notice, the original Warrant and (unless a cashless exercise
is intended) the Exercise Price. In the case of a dispute as to the calculation
of the Exercise Price or the number of Warrant Shares issuable hereunder
(including without limitation the calculation of any adjustment to the Exercise
Price pursuant to Section 6 below), the Company shall promptly issue to the
Holder the number of Warrant Shares that are not disputed and shall submit the
disputed calculations to the Company's independent accountant within two (2)
Business Days following the Exercise Date. The Company shall cause such
accountant to calculate the Exercise Price and/or the number of Warrant Shares
issuable hereunder and to notify the Company and the Holder of the results in
writing no later than two (2) Business Days following the day on which such
accountant received the disputed calculations. Such accountant's calculation
shall be deemed conclusive absent manifest error. The fees of any such
accountant shall be borne by the party whose calculations were most at variance
with those of such accountant.

          (c)  Early Expiration. In the event that following the Effective Date
               ----------------
of the Registration statement (as defined in the Registration Rights Agreement),
the Closing Bid Price (as defined herein) of the Common Stock during any period
of five (5) consecutive Trading Days (as defined in the Securities Purchase
Agreement) is equal to or greater than $2.00 (subject to adjustment as provided
herein) (the "First Expiration Trigger Event") or is equal to or greater than
              ------------------------------
$3.00 (subject to adjustment as provided herein) (the "Second Expiration Trigger
                                                       -------------------------
Event"), the Company may deliver to the Holder at any time that the Closing Bid
-----
Price equals or exceeds $2.00 in the case of the First Expiration Trigger Event
or $3.00 in the case of the Second Expiration Trigger Event, written notice (the
"Early Expiration Notice") that the Warrant shall expire for up to an aggregate
 -----------------------
of one-third (1/3 rd) of the Initial Shares for each of the First Expiration
Trigger Event and Second Expiration Trigger Event.  In the event that the
Company delivers to the Holder an Early Expiration Notice in accordance with the
foregoing, this Warrant shall expire with respect to the number of shares
indicated in the Early Expiration Notice on the date (the "Early Expiration
                                                           ----------------
Date") which is thirty (30) Business Days following the Business Day on which
----
such Early Expiration Notice is delivered to the Holder.  The Company may give
more than one Early Expiration Notice with respect to each of the First
Expiration Trigger Event and Second Expiration Trigger Event so long as the
aggregate number of shares subject to all such notices for each of the First and
Second Expiration Trigger Events does not exceed one-third (1/3 rd) of the
Initial Shares.  The "Closing Bid Price" shall mean, with respect to the Common
                      -----------------
Stock, the Closing Bid Price for the Common Stock occurring on a given Trading
Day on the principal securities exchange or trading market where such security
is listed or traded as reported by Bloomberg Financial Markets ("Bloomberg") or,
if Bloomberg is not then reporting such prices, by a comparable reporting
service of national reputation selected by the Company or if the foregoing does
not apply, the last reported bid price of such security in the over-

                                       22
<PAGE>

the-counter market on the electronic bulletin board for such security as
reported by Bloomberg or, if no bid price is reported for such security by
Bloomberg, the average of the bid prices of all market makers for such security
as reported in the "pink sheets" by the National Quotation Bureau, Inc.

          (d)  Cancellation of Warrant. This Warrant shall be canceled upon its
               -----------------------
exercise and, if this Warrant is exercised in part, the Company shall, at the
time that it delivers Warrant Shares to the Holder pursuant to such exercise as
provided herein, issue a new warrant, and deliver to the Holder a certificate
representing such new warrant, with terms identical in all respects to this
Warrant (except that such new warrant shall be exercisable into the number of
shares of Common Stock with respect to which this Warrant shall remain
unexercised); provided, however, that the Holder shall be entitled to exercise
all or any portion of such new warrant at any time following the time at which
this Warrant is exercised, regardless of whether the Company has actually issued
such new warrant or delivered to the Holder a certificate therefor.

     2. Delivery of Warrant Shares Upon Exercise.

     Upon receipt of an Exercise Notice pursuant to paragraph 1 above, the
Company shall, (A) in the case of a Cashless Exercise (as defined below), no
later than the close of business on the third (3rd) Business Day following the
Exercise Date set forth in such Exercise Notice, (B) in the case of a Cash
Exercise (as defined below) no later than the close of business on the later to
occur of (i) the third (3rd) Business Day following the Exercise Date set forth
in such Exercise Notice and (ii) such later date on which the Company shall have
received payment of the Exercise Price, and (C) with respect to Warrant Shares
which are disputed as described in paragraph 1(b) above, and required to be
delivered by the Company pursuant to the accountant's calculations described
therein, the close of business on the third (3rd) Business Day following the
determination made pursuant to paragraph 1(b) (the "Delivery Date"), issue and
                                                    -------------
deliver or caused to be delivered to the Holder the number of Warrant Shares as
shall be determined as provided herein. The Company shall effect delivery of
Warrant Shares to the Holder by, as long as the Company's designated transfer
agent for the Common Stock (the "Transfer Agent") participates in the Depository
                                 --------------
Trust Company ("DTC") Fast Automated Securities Transfer program ("FAST"),
                ---                                                ----
crediting the account of the Holder or its nominee at DTC (as specified in the
applicable Exercise Notice) with the number of Warrant Shares required to be
delivered, no later than the close of business on such Delivery Date. In the
event that the Transfer Agent is not a participant in FAST, or if Warrant Shares
are not otherwise eligible for delivery through FAST, or if the Holder so
specifies in an Exercise Notice or otherwise in writing on or before the
Exercise Date, the Company shall effect delivery of Warrant Shares by delivering
to the Holder or its nominee physical certificates representing such Warrant
Shares, no later than the close of business on such Delivery Date. Warrant
Shares delivered to the Holder shall not contain any restrictive legend as long
as the resale of such Warrant Shares is covered by an effective Registration
Statement (as defined in the Registration Rights Agreement) and such Holder
represents in writing to the Company that such Warrant Shares (i) have been or
are being sold pursuant to such registration statement or pursuant to Rule 144
under the

                                       23
<PAGE>

Securities Act of 1933, as amended, or (ii) may be made pursuant to Rule 144(k)
under the Securities Act of 1933, as amended, or any successor rule or
provision.

     3. Failure to Deliver Warrant Shares.

     (a)  Exercise Default. In the event that, as a result of any action or
          ----------------
failure to act on the part of the Company (including without limitation a
failure by the Company to have a sufficient number of shares of Common Stock
authorized and reserved for issuance pursuant to exercise of the Warrants), the
Company does not deliver to a Holder certificates representing the number of
Warrant Shares specified in the applicable Exercise Notice on or before the
Delivery Date therefor and such failure continues for ten (10) Business Days (an
"Exercise Default"), the Company shall pay to the Holder payments ("Exercise
 ----------------                                                   --------
Default Payments") in the amount of (i) (N/365) multiplied by (ii) the aggregate
----------------                                ----------
Exercise Price for the Warrant Shares which are the subject of such Exercise
Default multiplied by (iii) the lower of twenty four percent (24%) and the
        ----------
maximum rate permitted by applicable law, where "N" equals the number of days
elapsed between the original Delivery Date for such Warrant Shares and the date
on which all of such Warrant Shares are issued and delivered to the Holder.
Amounts payable under this subparagraph 3(a) shall be paid to the Holder in
immediately available funds on or before the fifth (5th) Business Day of the
calendar month immediately following the calendar month in which such amount has
accrued.

     (b)  Buy-in. Nothing herein shall limit a Holder's right to pursue actual
          ------
damages for the Company's failure to issue and deliver Warrant Shares in
connection with an exercise on the applicable Delivery Date (including, without
limitation, damages relating to any purchase of shares of Common Stock by the
Holder to make delivery on a sale effected in anticipation of receiving Warrant
Shares upon exercise, such damages to be in an amount equal to (A) the aggregate
amount paid by the Holder for the shares of Common Stock so purchased minus (B)
                                                                      -----
the aggregate amount of net proceeds, if any, received by the Holder from the
sale of the Warrant Shares issued by the Company pursuant to such exercise), and
the Holder shall have the right to pursue all remedies available to it at law or
in equity (including, without limitation, a decree of specific performance
and/or injunctive relief).

     (c)  Reduction of Exercise Price. In the event that, as a result of any
          ---------------------------
action or failure to act on the part of the Company (including without
limitation a failure by the Company to have a sufficient number of shares of
Common Stock authorized and reserved for issuance pursuant to exercise of the
Warrants), a Holder has not received certificates representing the Warrant
Shares by the tenth (10th) Business Day following an Exercise Default, the
Holder may, upon written notice to the Company, regain on such Business Day the
rights of a Holder of this Warrant, or part thereof, with respect to the Warrant
Shares that are the subject of such Exercise Default, and the Exercise Price for
such Warrant Shares shall be reduced by one percent (1%) for each day beyond
such 10th Business Day in which the Exercise Default continues. In such event,
the Holder shall retain all of the Holder's rights and remedies with respect to
the Company's failure to

                                       24
<PAGE>

deliver such Warrant Shares (including without limitation the right to receive
the cash payments specified in subparagraph 3(a) above).

     (d)  Holder of Record. Each Holder shall, for all purposes, be deemed to
          ----------------
have become the holder of record of Warrant Shares on the Exercise Date of this
Warrant, irrespective of the date of delivery of such Warrant Shares. Nothing in
this Warrant shall be construed as conferring upon the Holder hereof any rights
as a stockholder of the Company prior to the Exercise Date.

     4. Exercise Limitations.

     Notwithstanding anything to the contrary contained herein, prior to the
Nasdaq Notice (as defined in the Securities Purchase Agreement), this Warrant
shall not be exercisable by the Holder to the extent (but only to the extent)
that, if exercised by the Holder, the Holder, including all affiliates of the
Holder, would be entitled to vote more than twenty percent (20%) of the
Company's securities entitled to vote on matters to be voted on by the Company's
stockholders.  In this event, the Holder shall, in connection with any such
exercise, grant to the Company's Board of Directors an irrevocable proxy to vote
all shares of the Holder's Common Stock on any matter brought to the vote of the
Company's stockholders in accordance with the decision of a majority of such
directors, so long as, but only so long as and only to the extent that such
shares, with all other shares of the Company's securities owned (not including
for this purpose any warrants, options or convertible securities, so long as
such securities do not have the right to vote on matters brought to a vote of
the Company's stockholders) by the Holder, including all affiliates of the
Holder, represent more than twenty percent (20%) of the Company's securities
entitled to vote on matters to be voted on by the Company's stockholders.  For
clarification, it is expressly a term of this security that the limitations
contained in this Section 4 shall apply to each successive Holder.  The
restriction contained in this Section 4 may not be altered, amended, deleted or
changed in any manner whatsoever unless the holders of a majority of the
outstanding shares of Common Stock approve such alteration, amendment, deletion
or change.  If at the time of the first meeting of the Company's stockholders
following the First Closing (as defined in the Securities Purchase Agreement)
the total number of shares of Common Stock beneficially owned by the Holder of
this Warrant exceeds twenty percent (20%), the Company shall use it bests
efforts to cause its stockholders to approve the removal of this restriction on
the  Holder's right to vote its shares of the Common Stock.  If the Company is
not able to obtain such approval by August 31, 2002, the Company shall pay the
Holder $50,000 in consideration for its failure to obtain such approval.

     5. Payment of the Exercise Price.

     The Holder may pay the Exercise Price in either of the following forms or,
at the election of Holder, a combination thereof:

          (a) Cash Exercise: by delivery of immediately available funds.

                                       25
<PAGE>

          (b) Cashless Exercise: by surrender of this Warrant to the Company
together with a notice of cashless exercise, in which event the Company shall
issue to the Holder the number of Warrant Shares determined as follows:

                  Y  x  (A  --  B)
          X   =   ----------------
                         A

where:    X = the number of Warrant Shares to be issued to the Holder.

          Y = the number of Warrant Shares with respect to which this Warrant is
              being exercised.

          A = the average of the Closing Bid Prices of the Common Stock for the
              five (5) Trading Days immediately prior to (but not including) the
              Exercise Date.

          B = the Exercise Price;

provided, however, that the Holder may exercise this Warrant pursuant to a
Cashless Exercise only if, on the Exercise Date, the resale of Warrant Shares is
not covered by an effective Registration Statement (as defined in the
Registration Rights Agreement) that is available to the Holder on such date.

     For purposes of Rule 144 under the Securities Act of 1933, as amended, it
is intended, understood and acknowledged that the Warrant Shares issued in a
cashless exercise transaction shall be deemed to have been acquired by the
Holder, and the holding period for the Warrant Shares shall be deemed to have
been commenced, on the Issue Date.

     6. Anti-Dilution Adjustments; Distributions; Other Events.

     The Exercise Price and the number of Warrant Shares issuable hereunder
shall be subject to adjustment from time to time as provided in this Section 6.
In the event that any adjustment of the Exercise Price or number of Warrant
Shares as required herein results in a fraction of a cent or fraction of a
share, as applicable, such Exercise Price or number of Warrant Shares shall be
rounded up or down to the nearest cent or share, as applicable.

          (a)  Adjustment of Exercise Price and Number of Shares upon Issuance
               ---------------------------------------------------------------
of Common Stock.  Except as otherwise provided in Section 6(c) hereof, if and
---------------
whenever after the Issue Date, the Company issues or sells, or in accordance
with Section 6(b) hereof is deemed to have issued or sold, any shares of Common
Stock for no consideration (other than a stock split or stock dividend) or for a
consideration per share less than the Exercise Price (as then in effect)(other
than  issuances of Common Stock (i) pursuant to an employee stock purchase plan
or upon the exercise of options issued under a stock option plan duly

                                       26
<PAGE>

adopted by the Company, (ii) in connection with a merger, acquisition or
strategic investment which, in any such case, is not effected for the primary
purpose of raising equity capital,, (iii) pursuant to securities outstanding on
the Issue Date and issued pursuant to the terms of the Securities Purchase
Agreement or (iv) in connection with a firm-commitment underwritten secondary
offering) (a "Dilutive Issuance"), then effective immediately upon the Dilutive
Issuance, the Exercise Price will be adjusted in accordance with the following
formula:

                                 E' = (E)(O+P/E)
                                      ----------
                                        (CSDO)
where:

     E'    =  the adjusted Exercise Price;

     E     =  the then current Exercise Price;

     O     =  the number of shares of Common Stock outstanding prior to the
     Dilutive Issuance; immediately

     P     =  the aggregate consideration, calculated as set forth in Section
     6(b) hereof, received by the Company upon such Dilutive Issuance; and

     CSDO  =  the total number of shares of Common Stock Deemed Outstanding (as
     herein defined) immediately after the Dilutive Issuance.

          (b)  Effect on Exercise Price of Certain Events.  For purposes of
               ------------------------------------------
determining the adjusted Exercise Price under Section 6(a) hereof, the following
will apply:

               (i)  Issuance of Rights or Options.  If, after the date hereof,
                    -----------------------------
the Company in any manner issues or grants any warrants, rights or options,
whether or not immediately exercisable, to subscribe for or to purchase Common
Stock or other securities exercisable, convertible into or exchangeable for
Common Stock ("Convertible Securities")(such warrants, rights and options to
purchase Common Stock or Convertible Securities are hereinafter referred to as
"Options"), and the price per share for which Common Stock is purchasable or
issuable upon the exercise of such Options is less than the Exercise Price (as
then in effect) on the date of issuance of such Option or direct stock grant
("Below Market Options"), then the maximum total number of shares of Common
Stock issuable upon the exercise of all such Below Market Options (assuming full
exercise, conversion or exchange of Convertible Securities, if applicable) will,
as of the date of the issuance or grant of such Below Market Options, be deemed
to be outstanding and to have been issued and sold by the Company for such price
per share. For purposes of the preceding sentence, the price per share for which
Common Stock is issuable upon the exercise of such Below Market Options is
determined by dividing (i) the total amount, if any, received or receivable by
the Company as consideration for the issuance or sale of all such Below Market
Options, plus the minimum aggregate amount of additional consideration, if any,
payable to the Company upon the exercise of all such Below Market

                                       27
<PAGE>

Options, plus, in the case of Convertible Securities issuable upon the exercise
of such Below Market Options, the minimum aggregate amount of additional
consideration payable upon the exercise, conversion or exchange thereof at the
time such Convertible Securities first become exercisable, convertible or
exchangeable, by (ii) the maximum total number of shares of Common Stock
issuable upon the exercise of all such Below Market Options (assuming full
conversion of Convertible Securities, if applicable). No further adjustment to
the Exercise Price will be made upon the exercise of such Below Market Options
or upon the exercise, conversion or exchange of Convertible Securities issuable
upon exercise of such Below Market Options.

               (ii)   Issuance of Convertible Securities.
                      ----------------------------------

                      (A)  If the Company in any manner issues or sells any
Convertible Securities, whether or not immediately convertible (other than where
the same are issuable upon the exercise of Options) and the price per share for
which Common Stock is issuable upon such exercise, conversion or exchange (as
determined pursuant to Section 6(b)(ii)(B) if applicable) is less than the
Exercise Price (as then in effect) on the date of issuance of such Convertible
Security, then the maximum total number of shares of Common Stock issuable upon
the exercise, conversion or exchange of all such Convertible Securities will, as
of the date of the issuance of such Convertible Securities, be deemed to be
outstanding and to have been issued and sold by the Company for such price per
share. For the purposes of the preceding sentence, the price per share for which
Common Stock is issuable upon such exercise, conversion or exchange is
determined by dividing (i) the total amount, if any, received or receivable by
the Company as consideration for the issuance or sale of all such Convertible
Securities, plus the minimum aggregate amount of additional consideration, if
any, payable to the Company upon the exercise, conversion or exchange thereof at
the time such Convertible Securities first become exercisable, convertible or
exchangeable, by (ii) the maximum total number of shares of Common Stock
issuable upon the exercise, conversion or exchange of all such Convertible
Securities. No further adjustment to the Exercise Price will be made upon the
actual issuances of such Common Stock upon exercise, conversion or exchange of
such Convertible Securities.

                      (B)  If the Company in any manner issues or sells any
Convertible Securities with a fluctuating or re-setting conversion or exercise
price or exchange ratio (a "Variable Rate Convertible Security"), then the price
per share for which Common Stock is issuable upon such exercise, conversion or
exchange for purposes of the calculation contemplated by Section 6(b)(ii)(A)
shall be deemed to be the lowest price per share which would be applicable
assuming that (1) all holding period and other conditions to any discounts
contained in such Convertible Security have been satisfied, and (2) the
conversion or exercise price on the date of exercise, conversion or exchange of
such Convertible Security was 80% of the Closing Bid Price on the date of
issuance of such Convertible Security (the "Assumed Variable Market Price").

               (iii)  Change in Option Price or Conversion Rate.  If there is
                      -----------------------------------------
a change at any time in (i) the amount of additional consideration payable to
the Company upon the exercise of any Options; (ii) the amount of additional
consideration, if any, payable

                                       28
<PAGE>

to the Company upon the exercise, conversion or exchange of any Convertible
Securities; or (iii) the rate at which any Convertible Securities are
convertible into or exchangeable for Common Stock (other than under or by reason
of provisions designed to protect against dilution), the Exercise Price in
effect at such time shall be adjusted to the Exercise Price which would have
been in effect had such Options or Convertible Securities still outstanding
provided for such changed additional consideration or changed conversion rate,
as the case may be, at the time initially granted, issued or sold.

               (iv)   Treatment of Expired Options and Unexercised Convertible
                      --------------------------------------------------------
Securities.  If, in any case, the total number of shares of Common Stock
-----------
issuable upon exercise of any Options or upon exercise, conversion or exchange
of any Convertible Securities is not, in fact, issued and the rights to exercise
such Option or to exercise, convert or exchange such Convertible Securities
shall have expired or terminated, the Exercise Price then in effect will be
readjusted to the Exercise Price which would have been in effect at the time of
such expiration or termination had such Options or Convertible Securities, to
the extent outstanding immediately prior to such expiration or termination
(other than in respect of the actual number of shares of Common Stock issued
upon exercise or conversion thereof), never been issued.

               (v)    Calculation of Consideration Received. If any Common
                      -------------------------------------
Stock, Options or Convertible Securities are issued, granted or sold for cash,
the consideration received therefor for purposes of this Warrant will be the
amount received by the Company therefor, before deduction of reasonable
commissions, underwriting discounts or allowances or other reasonable expenses
paid or incurred by the Company in connection with such issuance, grant or sale.
In case any Common Stock, Options or Convertible Securities are issued or sold
for a consideration part or all of which shall be other than cash, the amount of
the consideration other than cash received by the Company will be the fair
market value of such consideration except where such consideration consists of
freely-tradable securities, in which case the amount of consideration received
by the Company will be the Market Price thereof as of the date of receipt. The
fair market value of any consideration other than cash or securities will be
determined in the good faith reasonable business judgment of the Board of
Directors.

               (vi)   Exceptions to Adjustment of Exercise Price. No adjustment
                      ------------------------------------------
to the Exercise Price will be made (i) upon the exercise or conversion of any
warrants, options or convertible securities issued and outstanding on the date
hereof in accordance with the terms of such securities as of such date; (ii)
upon the grant or exercise of any stock or options which may hereafter be
granted or exercised under any employee, consultant or director benefit plan of
the Company now existing or to be implemented in the future, so long as the
issuance of such stock or options is approved by a majority of the non-employee
members of the Board of Directors of the Company or a majority of the members of
a committee of non-employee directors established for such purpose; or (iii)
upon the issuance of any additional Common Stock pursuant to Section 4.12 of the
Securities Purchase Agreement or the exercise of the Warrants.

                                       29
<PAGE>

     (c)  Subdivision or Combination of Common Stock. If the Company, at any
          ------------------------------------------
time after the initial issuance of this Warrant, subdivides (by any stock split,
stock dividend, recapitalization, reorganization, reclassification or otherwise)
its shares of Common Stock into a greater number of shares, then after the date
of record for effecting such subdivision, the Exercise Price in effect
immediately prior to such subdivision will be proportionately reduced. If the
Company, at any time after the initial issuance of this Warrant, combines (by
reverse stock split, recapitalization, reorganization, reclassification or
otherwise) its shares of Common Stock into a smaller number of shares, then,
after the date of record for effecting such combination, the Exercise Price in
effect immediately prior to such combination will be proportionally increased.
In the event of any adjustment to the Exercise Price arising from an event
specified in this paragraph (c), the number of shares of Common Stock into which
this Warrant is exercisable will be proportionately increased or reduced, as the
case may be.

     (d)  Distributions. If the Company or any of its subsidiaries shall at any
          -------------
time distribute to holders of Common Stock (or to a holder, other than the
Company, of the common stock of any such subsidiary) cash, evidences of
indebtedness or other securities or assets (other than cash dividends or
distributions payable out of earned surplus or net profits for the current or
the immediately preceding year) including any dividend or distribution in shares
of capital stock of a subsidiary of the Company (collectively, a "Distribution")
                                                                  ------------
then, in any such case, the Holder of this Warrant shall be entitled to receive
at the time of the exercise of the Warrant, an amount and type of such
Distribution as though such Holder were a holder on the record date therefor of
a number of shares of Common Stock into which this Warrant is exercisable as of
such record date (such number of shares to be determined at the Exercise Price
then in effect and without regard to any limitation on exercise of this Warrant
that may exist pursuant to the terms hereof or otherwise).

     (e)  Additional Shares, Securities or Assets.  In the event that at any
          -----------------  --------------------
time, as a result of an adjustment made pursuant to this Section 6, the Holder
of this Warrant shall, upon exercise of this Warrant, become entitled to receive
securities or assets (other than Common Stock) then, wherever appropriate, all
references herein to shares of Common Stock shall be deemed to refer to and
include such shares and/or other securities or assets; and thereafter the number
of such shares and/or other securities or assets shall be subject to adjustment
from time to time in a manner and upon terms as nearly equivalent as practicable
to the provisions of this Section 6.

     (f) Special Adjustment and Notice of Adjustment.  Upon the occurrence of
         -------------------------------------------
any event which requires any adjustment of the Exercise Price, then, and in each
such case, the Company shall give notice thereof to the Holder, which notice
shall state the Exercise Price resulting from such adjustment and the increase
or decrease in the number of Warrant Shares purchasable at such price upon
exercise, setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based.  Such calculation shall be certified
by the chief financial officer of the Company.  If the Company takes any actions
(including under or by virtue of this Section 6) which would have a dilutive
effect on the Holder or which would materially and adversely affect the

                                       30
<PAGE>

Holder with respect to its investment in the Warrant, and if the provisions of
this Section 6, are not strictly applicable to such actions or, if applicable to
such actions, would not operate to equitably protect the Holder against such
actions, then the Company shall promptly upon notice from Holder appoint its
independent certified public accountants to determine as promptly as practicable
an appropriate adjustment to the terms hereof, including without limitation
adjustments to the Exercise Price, or another appropriate action to so equitably
protect such Holder and prevent any such dilution and any such material adverse
effect, as the case may be. Following such determination, the Company shall
forthwith make the adjustments or take the other actions described therein.

     (g)  Other Notices.  In case at any time:
          -------------

          (i)    the Company shall declare any dividend upon the Common Stock
payable in shares of stock of any class or make any other distribution to the
holders of the Common Stock;

          (ii)   the Company shall offer for subscription pro rata to the
holders of the Common Stock any additional shares of stock of any class or other
rights;

          (iii)  there shall be any capital reorganization of the Company, or
reclassification of the Common Stock, or consolidation or merger of the Company
with or into, or sale of all or substantially all of its assets to, another
corporation or entity; or

          (iv)   there shall be a voluntary or involuntary dissolution,
liquidation or winding-up of the Company;

then, in each such case, the Company shall give to the Holder (a) notice of the
date on which the books of the Company shall close or a record shall be taken
for determining the holders of Common Stock entitled to receive any such
dividend, distribution, or subscription rights or for determining the holders of
Common Stock entitled to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up and (b) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding-up, notice of
the date (or, if not then known, a reasonable approximation thereof by the
Company) when the same shall take place.  Such notice shall also specify the
date on which the holders of Common Stock shall be entitled to receive such
dividend, distribution, or subscription rights or to exchange their Common Stock
for stock or other securities or property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation, or
winding-up, as the case may be.  Such notice shall be given at least thirty (30)
days prior to the record date or the date on which the Company's books are
closed in respect thereto, but in no event earlier than public announcement of
such proposed transaction or event.  Failure to give any such notice or any
defect therein shall not affect the validity of the proceedings referred to in
clauses (i), (ii), (iii) and (iv) above.

                                       31
<PAGE>

     7.   Fractional Interests.

     No fractional shares or scrip representing fractional shares shall be
issuable upon the exercise of this Warrant, but on exercise of this Warrant, the
Holder hereof may purchase only a whole number of shares of Common Stock. If, on
exercise of this Warrant, the Holder hereof would be entitled to a fractional
share of Common Stock or a right to acquire a fractional share of Common Stock,
such fractional share shall be disregarded and the number of shares of Common
Stock issuable upon exercise shall be rounded up or down to the nearest whole
number of shares of Common Stock.

     8.   Transfer of this Warrant.

     The Holder may sell, transfer, assign, pledge or otherwise dispose of this
Warrant, in whole or in part, as long as such sale or other disposition is made
pursuant to an effective registration statement or an exemption to the
registration requirements of the Securities Act of 1933, as amended, and
applicable state laws. Upon such transfer or other disposition, the Holder shall
deliver a written notice to Company, substantially in the form of the Transfer
Notice attached hereto as Exhibit B (the "Transfer Notice"), indicating the
                                          ---------------
person or persons to whom this Warrant shall be transferred and, if less than
all of this Warrant is transferred or this Warrant is transferred in parts, the
number of Warrant Shares to be covered by the part of this Warrant to be
transferred to each such person. Within three (3) Business Days of receiving a
Transfer Notice and the original of this Warrant, the Company shall deliver to
the each transferee designated by the Holder a Warrant or Warrants of like tenor
and terms for the appropriate number of Warrant Shares. Notwithstanding the
foregoing, no Holder may knowingly and voluntarily sell this Warrant (or any
portion thereof) to an entity that is a competitor of the Company.

     9.   Benefits of this Warrant.

     Nothing in this Warrant shall be construed to confer upon any person other
than the Holder of this Warrant any legal or equitable right, remedy or claim
under this Warrant and this Warrant shall be for the sole and exclusive benefit
of the Holder of this Warrant.

     10.  Loss, theft, destruction or mutilation of Warrant.

     Upon receipt by the Company of evidence of the loss, theft, destruction or
mutilation of this Warrant, and (in the case of loss, theft or destruction) of
indemnity or security reasonably satisfactory to the Company, and upon surrender
of this Warrant, if mutilated, the Company shall execute and deliver a new
Warrant of like tenor and date.

     11.  Notice or Demands.

     Except as otherwise provided herein, any notice, demand or request required
or permitted to be given pursuant to the terms of this Warrant shall be in
writing and shall be deemed given (i) when delivered personally or by verifiable

                       to Securities Purchase Agreement

                         REGISTRATION RIGHTS AGREEMENT

     This REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of January
                                               ---------
17, 2002, by and among WEBB INTERACTIVE SERVICES, INC., a Delaware corporation
(the "Company"), and JONA, INC. (the "Purchaser").
      -------                         ---------

     The Company has agreed, on the terms and subject to the conditions set
forth in the Securities Purchase Agreement of even date herewith (the
"Securities Purchase Agreement"), to issue and sell to the Purchaser shares of
------------------------------
the Company's Common Stock, no par value (the "Common Stock") and a related
                                               ------------
warrant (the "Warrant").  The Warrants entitle the holder thereof to purchase
              -------
shares (the "Warrant Shares") of the Company's Common Stock.
             --------------

     In order to induce the Purchaser to enter into the Securities Purchase
Agreement, the Company has agreed to provide certain registration rights under
the Securities Act of 1933, as amended (the "Securities Act"), and under
                                             --------------
applicable state securities laws. Capitalized terms used herein and not
otherwise defined shall have the respective meanings set forth in the Securities
Purchase Agreement, including the exhibits thereto.

     In consideration of the Purchaser entering into the Securities Purchase
Agreement, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

1.   DEFINITIONS.

     For purposes of this Agreement, the following terms shall have the meanings

     (a)  "Business Day" shall have the meaning specified in the Securities
           ------------
Purchase Agreement;

     (b)  "Holder" means any person owning or having the right to acquire
           ------
through exercise of the Warrants, Registrable Securities, including initially
the Purchaser and thereafter any permitted assignee thereof;

     (c)  "Effective Date" means the date on which the Registration Statement is
          --------------

                                                                   ----------

     (d)  "Filing Deadline" means May 1, 2002;
           ---------------

     (e)  "Register", "registered" and "registration" refer to a registration
           --------    ----------       ------------
effected by preparing and filing a registration statement or statements in
compliance with the

                                       35
<PAGE>

Securities Act and pursuant to Rule 415 under the Securities Act ("Rule 415") or
                                                                   --------
any successor rule providing for the offering of securities on a continuous or
delayed basis ("Registration Statement"), and the declaration or ordering of
                ----------------------
effectiveness of the Registration Statement by the Commission; and

     (f)  "Registerable Securities" means the Common Stock issued in accordance
           -----------------------
with the term of the Securities Purchase Agreement and the Warrant Shares and
any shares of capital stock issued or issuable from time to time (with any
adjustments) in replacement of, in exchange for or otherwise in respect of the
Common Stock and  the Warrant Shares.

2.   MANDATORY REGISTRATION.

     (a)  On or before the Filing Deadline, the Company shall prepare and file
with the Commission a Registration Statement on Form S-3 as a "shelf"
registration statement under Rule 415 covering the resale of up to 7,500,000
shares of Common Stock issued pursuant to the Securities Purchase Agreement and
up to 7,500,000 Warrant Shares. The Registration Statement shall state, to the
extent permitted by Rule 416 under the Securities Act, that it also covers such
indeterminate number of shares of Common Stock as may be required to effect
exercise of the Warrants in order to prevent dilution resulting from stock
splits, stock dividends or similar events.

     (b)  The Company shall use its best efforts to cause the Registration
Statement to become effective as soon as practicable following the filing
thereof, but in no event prior to June 5, 2002. The Company shall respond
promptly to any and all comments made by the staff of the Commission on the
Registration Statement (but in no event later than fifteen (15) Business Days
following the Company's receipt thereof), and shall submit to the Commission,
within three (3) Business Days after the Company learns that no review of the
Registration Statement will be made by the staff of the Commission or that the
staff of the Commission has no further comments on the Registration Statement,
as the case may be, a request for acceleration of the effectiveness of the
Registration Statement to a time and date not later than forty eight (48) hours
after the submission of such request. The Company shall maintain the
effectiveness of the Registration Statement until the earlier to occur of (i)
the date on which all of the Registrable Securities have been sold pursuant to
the Registration Statement and (ii) the date on which all of the remaining
Registrable Securities (in the reasonable opinion of counsel to the Holders) may
be immediately sold to the public without registration and without regard to the
amount of Registrable Securities which may be sold by a Holder thereof at a
given time.

     (c)  If for any reason from time to time there are Registrable Securities
which are not included or which are not allowed to be included by the Commission
in a Registration Statement filed pursuant hereto, the Company shall file
additional Registration Statements as soon as practicable following a request by
any Holder to effect a registration of all of such Registrable Securities, which
Registration Statement shall be subject to all terms of this Agreement and shall
use its best efforts to cause such

                                       36
<PAGE>

Registration Statement to become effective as soon as practicable after such
filing. The Company shall maintain the effectiveness of each Registration
Statement until the earlier to occur of (i) the date on which all of the
Registrable Securities have been sold pursuant to the Registration Statement and
(ii) the date on which all of the remaining Registrable Securities (in the
reasonable opinion of counsel to the Holders) may be immediately sold to the
public without registration and without regard to the amount of Registrable
Securities which may be sold by a Holder thereof at a given time.

3.   PIGGYBACK REGISTRATION

     If at any time prior to the expiration of the Registration Period, (i) the
Company proposes to register shares of Common Stock under the Securities Act in
connection with the public offering of such shares for cash (other than a
registration relating solely to the sale of securities to participants in a
Company stock plan or employee stock award or a registration on Form S-4 under
the Securities Act or any successor or similar form registering stock issuable
upon a reclassification, a business combination involving an exchange of
securities or an exchange offer for securities of the issuer or another entity,
or a registration statement on Form S-3 covering the resale of securities issued
in connection with a corporate acquisition) (a "Proposed Registration") and (ii)
                                                ---------------------
a registration statement covering the sale of all of the Registrable Securities
is not then effective and available for sales thereof by the Holders, the
Company shall, at such time, promptly give each Holder written notice of such
Proposed Registration. Each Holder shall have twenty (20) days from its receipt
of such notice to deliver to the Company a written request specifying the amount
of Registrable Securities that such Holder intends to sell and such Holder's
intended method of distribution. Upon receipt of such request, the Company shall
use its best efforts to cause all Registrable Securities which the Company has
been requested to register to be registered under the Securities Act to the
extent necessary to permit their sale or other disposition in accordance with
the intended methods of distribution specified in the request of such Holder;
provided, however, that the Company shall have the right to postpone or withdraw
any registration effected pursuant to this Section 3 without obligation to the
Holder. If, in connection with any underwritten public offering for the account
of the Company or for shareholders of the Company that have contractual rights
to require the Company to register shares of Common Stock, the managing
underwriter(s) thereof shall impose a limitation on the number of shares of
Common Stock which may be included in the Registration Statement because, in the
judgment of such underwriter(s), marketing or other factors dictate such
limitation is necessary to facilitate such offering, then the Company shall be
obligated to include in such Registration Statement only such limited portion of
the Registrable Securities with respect to which each Holder has requested
inclusion hereunder as such underwriter(s) shall permit. Any such exclusion of
Registrable Securities shall be made pro rata among the Holders seeking to
include Registrable Securities in the Registration Statement, in proportion to
the number of Registrable Securities sought to be included by such Holders;
provided, however, that the Company shall not exclude any Registrable Securities
unless the Company has first excluded all outstanding securities, the holders of
which are not entitled to inclusion of such securities in such Registration
Statement or are not entitled to pro rata inclusion with the Registrable
Securities; and provided, further,

                                       37
<PAGE>

that, after giving effect to the immediately preceding proviso, any exclusion of
Registrable Securities shall be made pro rata with holders of other securities
having the right to include such securities in the Registration Statement.

4.   OBLIGATIONS OF THE COMPANY

     In addition to performing its obligations hereunder, including without
limitation those pursuant to paragraphs 2(a), 2(b) and 2(c) above, the Company
shall:

          (a)  promptly prepare and file with the Commission such amendments and
supplements to each Registration Statement and each prospectus used in
connection with the Registration Statement as may be necessary (i) to comply
with the provisions of the Securities Act or (ii) to maintain the effectiveness
of each Registration Statement during the applicable Registration Period, or as
may be reasonably requested within a reasonable time prior to any proposed sale
by a Holder in order to incorporate information concerning such Holder or such
Holder's intended method of distribution. The Company shall cause such
amendments and supplements to become effective as soon as practicable following
the filing thereof.

          (b)  secure the listing of all Registrable Securities on the Nasdaq
Stock Market prior to the date on which the Registration Statement relating to
such Registrable Securities becomes effective;

          (c)  furnish to each Holder such number of copies of the prospectus
included in such Registration Statement, including a preliminary prospectus, if
any, in conformity with the requirements of the Securities Act, and such other
documents as such Holder may reasonably request in order to facilitate the
disposition of such Holder's Registrable Securities;

          (d)  use all commercially reasonable efforts to register or qualify
the Registrable Securities under the securities or "blue sky" laws of such
jurisdictions within the United States as shall be reasonably requested from
time to time by a Holder, and do any and all other acts or things which may be
necessary or advisable to enable such Holder to consummate the public sale or
other disposition of the Registrable Securities in such jurisdictions; provided
that the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction;

          (e)  in the event of an underwritten public offering of the
Registrable Securities, enter into (together with all Holders proposing to
distribute Registrable Securities through such underwriting) and perform its
obligations under an underwriting agreement, in usual and customary form
reasonably acceptable to the Company, with the managing underwriter of such
offering;

          (f)  notify each Holder immediately upon the occurrence of any event
as a result of which the prospectus included in such Registration Statement, as
then in effect,

                                       38
<PAGE>

contains an untrue statement of material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in light of the circumstances then existing, and as promptly as
practicable, prepare, file and furnish to each Holder a reasonable number of
copies of a supplement or an amendment to such prospectus as may be necessary so
that such prospectus does not contain an untrue statement of material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements therein not misleading in light of the circumstances then
existing;

          (g)  use all commercially reasonable efforts to prevent the issuance
of any stop order or other order suspending the effectiveness of such
Registration Statement and, if such an order is issued, to obtain the withdrawal
thereof at the earliest possible time and to notify each Holder of the issuance
of such order and the resolution thereof;

          (h)  furnish to each Holder, on the date that such Registration
Statement becomes effective, (x) a letter, dated such date, of outside counsel
representing the Company (and reasonably acceptable to such Holder) addressed to
such Holder, confirming the effectiveness of the Registration Statement and, to
the knowledge of such counsel, the absence of any stop order, and (y) in the
case of an underwriting, (A) an opinion addressed to the underwriters, dated
such date, of such outside counsel, in such form and substance as is required to
be given to such underwriters, and (B) a letter addressed to such underwriters,
dated such date, from the Company's independent certified public accountants, in
such form and substance as is required to be given by the Company's independent
certified public accountants to such underwriters;

          (i)  provide each Holder and its representatives the opportunity to
conduct a reasonable inquiry of the Company's financial and other records during
normal business hours and make available its officers, directors and employees
for questions regarding information which such Holder may reasonably request in
order to fulfill any due diligence obligation on its part; and

          (j) permit counsel retained for such purpose by each Holder to review
the Registration Statement and all amendments and supplements thereto, and any
comments made by the staff of the Commission and the Company's responses
thereto, within a reasonable period of time prior to the filing thereof with the
Commission (or, in the case of comments made by the staff of the Commission,
within a reasonable period of time following the receipt thereof by the Company)
and amend such materials in accordance with the comments of such counsel.

5.   OBLIGATIONS OF EACH HOLDER

     In connection with the registration of the Registrable Securities pursuant
to the Registration Statement, each Holder shall:

                                       39
<PAGE>

          (a)  furnish to the Company in writing such information regarding
itself and the intended method of disposition of Registrable Securities as the
Company shall reasonably request in order to effect the registration thereof;

          (b)  upon receipt of any notice from the Company of the happening of
any event of the kind described in paragraphs 4(f) or 4(g), immediately
discontinue any sale or other disposition of Registrable Securities pursuant to
the Registration Statement until the filing of an amendment or supplement as
described in paragraph 4(f) or withdrawal of the stop order referred to in
paragraph 4(g);

          (c)  in the event of an underwritten offering of the Registrable
Securities, enter into a customary and reasonable underwriting agreement and
execute such other documents as the managing underwriter for such offering may
reasonably request;

          (d)  to the extent required by applicable law, deliver a prospectus to
the purchaser of Registrable Securities;

          (e)  notify the Company when it has sold all of the Registrable
Securities theretofore held by it; and

          (f)  promptly notify the Company in the event that any information
supplied by such Holder in writing for inclusion in the Registration Statement
or related prospectus is untrue or omits to state a material fact required to be
stated therein or necessary to make such information not misleading in light of
the circumstances then existing.

6.   INDEMNIFICATION.

     In the event that any Registrable Securities are included in a Registration
Statement under this Agreement:

          (a)  To the extent permitted by law, the Company shall indemnify and
hold harmless each Holder, the officers, directors, employees and agents of such
Holder, and each person, if any, who controls such Holder within the meaning of
the Securities Act or the Securities Exchange Act of 1934, as amended (the "1934
                                                                            ----
Act"), against any losses, claims, damages, liabilities or reasonable out-of-
---
pocket expenses (whether joint or several) (collectively, including legal or
other expenses reasonably incurred in connection with investigating or defending
same, "Losses"), insofar as any such Losses arise out of or are based upon (i)
       ------
any untrue statement or alleged untrue statement of a material fact contained in
such Registration Statement, including any preliminary prospectus, if any, or
final prospectus contained therein or any amendments or supplements thereto, or
(ii) the omission or alleged omission to state therein a material fact required
to be stated therein, or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading. Subject to the
provisions of paragraph 6(c) below, the Company will reimburse such Holder, and
each such officer, director, employee, agent or controlling person for any legal
or other expenses as reasonably incurred by any such

                                       40
<PAGE>

entity or person in connection with investigating or defending any Loss;
provided, however, that the foregoing indemnity shall not apply to amounts paid
in settlement of any Loss if such settlement is effected without the consent of
the Company (which consent shall not be unreasonably withheld), nor shall the
Company be obligated to indemnify any person for any Loss to the extent that
such Loss arises out of or is based upon and in conformity with written
information furnished by such person expressly for use in such Registration
Statement; and provided, further, that the Company shall not be required to
indemnify any person to the extent that any Loss results from such person
selling Registrable Securities (i) to a person to whom there was not sent or
given, at or prior to the written confirmation of the sale of such shares, a
copy of the prospectus, as most recently amended or supplemented, if the Company
has previously furnished or made available copies thereof or (ii) during any
period following written notice by the Company to such Holder of an event
described in paragraph 4(f) or 4(g).

          (b) To the extent permitted by law, each Holder, acting severally and
not jointly, shall indemnify and hold harmless the Company, the officers,
directors, employees, agents and representatives of the Company, and each
person, if any, who controls the Company within the meaning of the Securities
Act or the 1934 Act, against any Losses to the extent (and only to the extent)
that any such Losses arise out of or are based upon and in conformity with
written information furnished by such Holder expressly for use in such
Registration Statement; and such Holder will reimburse any legal or other
expenses as reasonably incurred by the Company and any such officer, director,
employee, agent, representative, or controlling person, in connection with
investigating or defending any such Loss; provided, however, that the foregoing
indemnity shall not apply to amounts paid in settlement of any such Loss if such
settlement is effected without the consent of such Holder, which consent shall
not be unreasonably withheld; provided, that, in no event shall any indemnity
under this paragraph 6(b) exceed the net proceeds resulting from the sale of the
Registrable Securities sold by such Holder under the Registration Statement.

          (c) Promptly after receipt by an indemnified party under this Section
6 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 6, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in and to assume the
defense thereof with counsel mutually satisfactory to the parties; provided,
however, that an indemnified party shall have the right to retain its own
counsel, with the reasonably incurred fees and expenses of one such counsel to
be paid by the indemnifying party, if representation of such indemnified party
by the counsel retained by the indemnifying party would be inappropriate under
applicable standards of professional conduct due to actual or potential
conflicting interests between such indemnified party and any other party
represented by such counsel in such proceeding. The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of
any such action, to the extent prejudicial to its ability to defend such action,
shall relieve such indemnifying party of any liability to the indemnified party
under this Section 6 with respect to such action, but the omission so to deliver
written

                                       41
<PAGE>

notice to the indemnifying party will not relieve it of any liability that it
may have to any indemnified party otherwise than under this Section 6 or with
respect to any other action unless the indemnifying party is materially
prejudiced as a result of not receiving such notice.

          (d) In the event that the indemnity provided in paragraph 6(a) or 6(b)
is unavailable or insufficient to hold harmless an indemnified party for any
reason, the Company and each Holder agree, severally and not jointly, to
contribute to the aggregate Losses to which the Company or such Holder may be
subject in such proportion as is appropriate to reflect the relative fault of
the Company and such Holder in connection with the statements or omissions which
resulted in such Losses; provided, however, that in no case shall such Holder be
responsible for any amount in excess of the proceeds resulting from the sale of
the Registrable Securities sold by it under the Registration Statement. Relative
fault shall be determined by reference to whether any alleged untrue statement
or omission relates to information provided by the Company or by such Holder.
The Company and each Holder agree that it would not be just and equitable if
contribution were determined by pro rata allocation or any other method of
allocation which does not take account of the equitable considerations referred
to above. Notwithstanding the provisions of this paragraph 6(d), no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to indemnification or contribution from
any person who is not guilty of fraudulent misrepresentation. For purposes of
this Section 6, each person who controls a Holder within the meaning of either
the Securities Act or the Exchange Act and each officer, director, employee or
agent of such Holder shall have the same rights to contribution as such Holder,
and each person who controls the Company within the meaning of either the
Securities Act or the Exchange Act and each officer, director, employee or agent
of the Company shall have the same rights to contribution as the Company,
subject in each case to the applicable terms and conditions of this paragraph
6(d).

          (e) The obligations of the Company and each Holder under this Section
6 shall survive the conversion of the Preferred Stock and exercise of the
Warrants in full, the completion of any offering of Registrable Securities
pursuant to a Registration Statement under this Agreement, or otherwise.

7. REPORTS.

     With a view to making available to each Holder the benefits of Rule 144
under the Securities Act ("Rule 144") and any other similar rule or regulation
                           --------
of the Commission that may at any time permit such Holder to sell securities of
the Company to the public without registration, the Company agrees to:

          (a) make and keep public information available, as those terms are
understood and defined in Rule 144;

               (b) file with the Commission in a timely manner all reports and
other

                                       42
<PAGE>

documents required to be filed by the Company under the Securities Act and the
1934 Act; and

          (c) furnish to such Holder, so long as such Holder owns any
Registrable Securities, forthwith upon written request (i) a written statement
by the Company, if true, that it has complied with the reporting requirements of
Rule 144, and the 1934 Act, (ii) to the extent not publicly available through
the Commission's EDGAR database, a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the
Company, and (iii) such other information as may be reasonably requested in
availing such Holder of any rule or regulation of the Commission which permits
the selling of any such securities without registration.

8.   MISCELLANEOUS.

     (a) Expenses of Registration. All expenses, other than underwriting
         ------------------------

waiver of the provisions of this Agreement may be made only pursuant to a
written instrument executed by the party against whom enforcement is sought. Any
amendment or waiver effected in accordance with this paragraph shall be binding
upon each Holder, each future Holder, and the Company. The failure of any party
to exercise any right or remedy under this Agreement or otherwise, or the delay
by any party in exercising such right or remedy, shall not operate as a waiver
thereof.

     (c) Notices. Any notice, demand or request required or permitted to be
