less favorably than to any other third party. NBC shall use commercially
reasonable efforts to furnish DCCI with pre-approvals in connection with
DCCI's use of the NBC Marks and NBC Links as soon as possible but in no event
later than sixty (60) days before July 1, 2000. Without limitation of the
foregoing, (a) NBC further authorizes DCCI to cause the DCCI Virtual Network
to appear on and in connection with NBC Controlled Linked Websites, and
warrants and represents that it has the right to do so; (b) NBC agrees that
the NBC:Cue Users shall not direct :Cues to any Non-NBC Controlled Linked
Websites unless (i) NBC first has delivered to the party or parties that own
and control such Non-NBC Controlled Linked Website a standards and practices
fact sheet, prepared by DCCI, describing such :Cues, that shall include the
appearance of the DCCI Virtual Network on and in connection therewith, and
given such party a reasonable opportunity to object; (ii) NBC has used
reasonable commercial efforts to obtain an written explicit authorization from

equally.

                  2.4      OWNERSHIP OF TRADEMARKS. Each Party agrees that the
Marks of the other Party are and will remain the sole property of such other
Party. Neither DCCI nor NBC shall do anything inconsistent with such
ownership. All uses by one Party of the other Party's Marks, including all
goodwill generated by the party using such Marks, shall accrue and inure to
the benefit of and be on behalf of the owner of such Marks. DCCI and NBC each

manner without prior written authorization from the owner of such Marks. DCCI
and NBC each shall (i) cause the appropriate designation-TM- or the
registration symbol-Registered Trademark- to be placed adjacent to the other
Party's Marks in connection with each use or display thereof and to indicate
such additional information as the owner of the Marks shall reasonably
specify from time to time concerning the use of its Marks, and (ii) comply
with all applicable laws pertaining to trademarks in force. In the event that
either DCCI or NBC reasonably determines that its Marks are being used by the
other Party in a manner that is inconsistent with the owner's quality
standards and reasonably demonstrates such inconsistency to the other Party,
the other Party will within thirty (30) days thereafter cure such
inconsistency or cease such use. Except as expressly granted in this
Agreement, each Party shall have no other rights of any kind in the Marks of
the other Party. Under no circumstances will anything in this Agreement be
construed as granting, by implication, estoppel or otherwise, a license to
any of DCCI's or NBC's Intellectual Property other than the use of each
Party's respective Marks in accordance with the terms of this Agreement. DCCI
and NBC each acknowledge that the other's Marks are the sole property of such
Party, and this Agreement only grants DCCI and NBC a limited right to use the
Marks of the other Party under the terms and conditions of this Agreement.

whole or in part, to any third party unless specifically authorized in this
Agreement. The foregoing notwithstanding, DCCI shall have no right, title or
interest in the NBC Marks, NBC Links, content owned by NBC or content

<PAGE>

level of promotion and content usage such that on-line consumer response does
not exceed the on-line infrastructure capacities of the respective NBC
division or NBC-Related Website. There shall be no cross-collateralization
(i.e., deferring, crediting, etc.) between or among NBC :Cue Users and/or
between or among kinds and number of :Cues, programming half-hours or days, as

or controlled by NBC shall use reasonable efforts to promote the :CRQ :Cue

Agreement) use of the :CRQ :Cue Technology, NBC shall place the DCCI Icon and

use commercially reasonable efforts to have such DCCI Icon and mutually
approved explanatory text placed on the Non-NBC Controlled Linked Websites.
The DCCI Icon, when activated, will allow a user to download the :CRQ Software
to such user's personal computer. NBC shall place the DCCI Icon on pages not
more than one click away from the home pages of CNBC.com and all websites for
NBC Stations. NBC shall use commercially reasonable efforts to arrange for the
DCCI Icon to be placed on pages not more than one click away from the home
pages of all other NBC-Related Websites; provided, that if any such other
NBC-Related Websites declines to place the DCCI Icon not more than one click
away from its home page, then such other NBC-Related Website shall not be
entitled to place the DCCI Icon on its site, unless DCCI authorizes placement
of the DCCI Icon thereon.

                  3.2      NBC'S EXCLUSIVITY.

                           (a)      EXCLUSIVITY WITH RESPECT TO USE OF :CUES.
During the Term of this Agreement, NBC Stations shall have the exclusive right
to use of the :CRQ :Cue Technology in local programs in the respective NBC
Stations' Markets as against (i) the CBS and ABC television networks solely
with respect to advertisements and promotional spots (including corporate
promotional spots for such networks and public service announcements, but
explicitly excluding any content-related material) inserted by such networks
into local programming, and (ii) the owned and operated stations and network
affiliated stations of CBS Corp. ("CBS"), or ABC, Inc. ("ABC") in the United
States of America, except for the Dallas, Texas Market where DCCI has
previously granted Belo Enterprises, Inc. ("BELO") the exclusive right to run
:Cues in television programming in the Dallas, Texas Market and in which
Dallas Market NBC Stations may not exploit the rights granted to other NBC
Stations hereunder. If, by June 1, 2000, NBC commits in a written notice
received by DCCI to running at least two (2) Content :Cues on the NBC Network
during Network Prime Time hours per day during NBC's television coverage of
the 2000 Olympics ("OLYMPICS COMMITMENT"), NBC will receive additional
exclusivity rights against CBS, ABC, Fox Broadcasting Network ("FOX") in the
United States of America through December 31, 2000, and DCCI shall not license
or allow CBS, ABC, Fox Networks to telecast: Cues through December 31, 2000.
NBC shall have the non-exclusive right to use of the :CRQ :Cue Technology in
local programs in the Caribbean area and in Puerto Rico on its owned and
operated stations. At such time as DCCI desires to make available a
Pan-European or Pan-Asian license to a third party during the Term, DCCI shall
grant NBC a thirty (30) day right of first negotiation for such licenses.

                           (b)      EXCLUSIVITY ON DCCI'S VIRTUAL NETWORK.

                                      11
<PAGE>

                                    (i)  During the Term and subject to the
terms of this Agreement, NBC shall have the exclusive right to occupy three
(3) sections of the Category Tab Bar (as defined in Section 1.16 above)
entitled "Search," "Business" and "News". For the avoidance of doubt, NBC
shall have exclusivity during the Term with respect to the categories of
Search, Business and News on the Category Tab Bar. By way of example only,
DCCI could not during the Term include on the Category Tab Bar another tab
entitled "CNN" or "Yahoo" without NBC's approval. In connection NBC's presence
on the Category Tab Bar, DCCI shall place NBC Marks in sections of the
Category Tab Bar consistent with other tabs on Category Tab Bar). If DCCI
needs to alter the NBC Marks to place them in the Category Tab Bar, DCCI shall
obtain pre-approval from NBC. DCCI shall not discriminate against NBC in terms
of the size and placement of any section of the Category Tab Bar that NBC is
entitled to occupy.

                                    (ii) If NBC makes the Olympics Commitment
or if General Electric Corp. or an Affiliate enters into a meaningful written
agreement with DCCI for a commercial application of the :CRQ :Cue Technology,
NBC shall have the right to have an NBC Link and/or NBC Mark as specified by
NBC and reasonably approved by DCCI continuously reside, on a non-exclusive
basis, during the Term on the Virtual Network on the Third Party Banner Bar
(as defined in Section 1.16 above). DCCI shall place the NBC Link on the
Virtual Network in the format provided by NBC as approved by DCCI (such
approval not to be unreasonably withheld or delayed). If DCCI needs to alter
the NBC Link to place it on the Virtual Network, DCCI shall obtain
pre-approval from NBC. NBC shall have the option of being adjacent to, and to
the right of, Radio Shack/Tandy on the Virtual Network and shall be accorded a
link no less favorable with respect to size and prominence as those accorded
to third parties with permanent "Bugs" (i.e. permanent hyper-linked icons) on
the Virtual Network.

                                    (iii) Other than as set forth in this
Agreement, DCCI shall have exclusive control of the look-and-feel and content
of the Virtual Network.

                           (c) EXCLUSIVITY WITH RESPECT TO NEWSPAPER
PUBLISHERS. During the Term and subject to the terms of this Agreement, DCCI
shall consult with NBC before DCCI enters into any exclusive agreement with
any newspaper in any of the Market areas of NBC Stations for such newspaper's
exclusive use of any DCCI technology related to the :Cat Scanner.

Party shall, and hereby does, irrevocably assign to the other Party a
one-half, undivided interest in and to any and all such right, title and
interest therein. NBC shall comply with DCCI's privacy policies; provided,
that DCCI shall not make any changes to such privacy policies in bad faith in
order to defeat NBC's rights to data under this Agreement. All other data,

Term, DCCI shall provide NBC with copies of all of the :CRQ Software/NBC User
Data on a monthly basis via the delivery method and in the format generally
used by DCCI to provide data and information to its other partners. The
Parties shall work together to ensure that NBC is able to access and interpret
such data in a cost effective manner.

                  4.3      ACCESS TO :CUE/NBC USER DATA. If at any time during
the Term DCCI sells, barters or otherwise shares Personal Data regarding any

with a third party acting on DCCI's behalf that does not sell, barter or
otherwise share such Personal Data with third parties, (b) de minimis
non-commercial disclosures on isolated occasions, and (c) confidentially as
required by any court or other governmental authority or as otherwise required
by law), then DCCI shall immediately take all steps reasonably necessary (i)
to provide NBC with copies of all of the :Cue/NBC User Data previously
collected by DCCI during the Term, and (ii) provide NBC with copies of all of
the :Cue/NBC User Data collected thereafter during the Term, with such data to
be provided to NBC via the delivery method and in the format generally used by

work together to ensure that NBC is able to access and interpret such data in
a cost effective manner.

foregoing, DCCI shall provide NBC with copies of all aggregated data (but not
any Personal Data associated therewith) collected by DCCI during the Term with
respect to all registered users of the :CRQ Software who have received a :Cue
from NBC :Cue Users during the Term, including without limitation the number
of registered users, demographic data with respect to such users, source of
the :CRQ Software, and breakdown of the number of Content :Cues, Promotional
:Cues and Commercial :Cues delivered, with such data to be provided to NBC via
the delivery method and in the format generally used by DCCI to provide data
and information to its other partners; provided, that the amount and quality
of such aggregated data provided to

                                      13

<PAGE>

NBC shall be no less than that provided to any other partner of DCCI. The
Parties shall work together to ensure that NBC is able to access and interpret
such data in a cost effective manner.

Agreement and any exhibits thereto in accordance with the DCCI Service Levels
attached as Exhibit 5.1 hereto, which is incorporated herein by reference;
provided, that if at any time DCCI provides more favorable service level
guarantees to any other user of the :CRQ :Cue Technology, then the NBC :Cue
Users shall automatically and without any further action be granted the
benefit of such more favorable service levels, and Exhibit 5.1 shall be deemed
replaced by such more favorable service levels. Without limitation to any
other service covenants in this Agreement, each of the Parties represents and

DCCI's Virtual Network, DCCI shall obtain pre-approval from NBC, not to be
unreasonably withheld. DCCI shall not discriminate against NBC in terms of the
size of, placement of or other parameter relating to any NBC Mark and NBC link
that NBC is entitled to place on DCCI's Virtual Network.

6.       LICENSE FEE

                  6.1      FEES. In consideration for DCCI's licenses
hereunder, NBC shall pay DCCI (provided DCCI shall bill and accept payment by

order to link viewers directly or indirectly to one or more Linked Websites
that are controlled by one or more third parties, and pursuant to which such

percent (80%) to the applicable NBC :Cue User and twenty percent (20%) to
DCCI, with the more specific terms of such arrangement to be mutually agreed;
and failing such agreement, Content and Promotional :Cues must run free of

more than fifty percent (50%) of the aggregate voting power of the then
outstanding securities of DCCI; (b) any merger, consolidation or other

stated herein, if this Agreement is terminated for any reason by either DCCI
or NBC, all rights and licenses granted pursuant to this Agreement shall
immediately revert and be fully vested in the grantor. In such event, each
Party shall promptly return to the other Party all Intellectual Property,

Party hereunder, unless otherwise agreed. In addition, NBC shall have forty
five (45) days to submit or cause the NBC :Cue Users to submit a :Cue Report

10.      INDEMNIFICATION.

                  10.1     INFRINGEMENT INDEMNIFICATION.

DCCI shall indemnify, defend and hold harmless NBC, the NBC :Cue Users, their
Affiliates and their respective officers, shareholders, agents, directors,
members, employees and agents (the "RELATED INDEMNIFIED PARTIES"), from and
against any and all losses, claims, liabilities, damages, costs and expenses
(including, without limitation, reasonable outside attorneys' fees) arising
out of or incurred by any NBC Party as a result of any actual or threatened
third party (i.e., not an Affiliate, for the purposes of this Section 10)
claim, action, investigation, proceeding or suit (each, a "CLAIM") alleging
that the licensing, use, reproduction, display, publishing, distribution or
other exploitation of the :CRQ :Cue Technology by any of the NBC Parties in
accordance with the rights granted hereunder constitutes an infringement,
dilution or unauthorized use of any patent, copyright, trademark, trade
secret, proprietary information, right of privacy or any other proprietary

shall indemnify, defend and hold harmless DCCI and its Related Indemnified
Parties from and against any and all Claims alleging that the licensing, use,
reproduction, display, publishing distribution

                                      19

<PAGE>

and other exploitation of content and/or software contained on all NBC
Controlled Linked Websites, and/or in the programming of any NBC:Cue User,
constitutes an Infringement, or that NBC's authorization of any such link was
not permitted. To the extent that NBC obtains an indemnity from parties who
own or control any and all Non-NBC Controlled Linked Websites to indemnify,
defend and hold harmless NBC and/or its Related Indemnified Parties from and
against Claims alleging that the licensing, use, reproduction, display,
publishing distribution and other exploitation of content and/or software
contained on such Non-NBC Controlled Linked Websites, constitutes an
Infringement, NBC shall indemnify, defend and hold harmless DCCI and its
Related Indemnified Parties from such Claims to the same extent.

                           (a)      In the event some or all of the :CRQ :Cue
Technology is held by a court of competent jurisdiction to infringe a third
party proprietary right, an injunction is obtained against use of any material
portion of the :CRQ :Cue Technology, then DCCI shall promptly, at its option
and expense, either: (i) procure for NBC the right to continue to use the

11.      CONFIDENTIALITY.

                  11.1     GENERAL. Confidential Information is all

confidential, including, without limitation, all technical data, trade
secrets, plans for products or services, customer data or lists, marketing

other Party, shall not use such Confidential Information except as set forth
herein, and shall not disclose such Confidential Information to any third
party. Without limiting the foregoing, each of the Parties shall use at least

Confidential Information disclosed to it by the other Party under this
Agreement, but in no event less than reasonable care. Each Party shall

unauthorized disclosure of the other Party's Confidential Information. Upon
expiration or termination of this Agreement, each Party shall return all
Confidential Information received from the other Party. Any breach of the
restrictions contained in this Section 11 is a breach of this Agreement that
may cause irreparable harm to the nonbreaching Party. Any such breach shall
entitle the nonbreaching Party to injunctive relief in addition to all legal
remedies.

                  11.2     EXCLUSIONS. Notwithstanding the above, neither
Party shall have liability to the other with regard to any Confidential

receiving Party, (ii) was known to the receiving party through legal means and
without restriction, at the time of disclosure, (iii) is disclosed with the
prior written approval of the disclosing Party, (iv) was independently
developed by the receiving Party without any use of the Confidential
Information, as reasonably demonstrated by the receiving Party, (v) becomes
known

                                      21

<PAGE>

to the receiving Party, without restriction, from a source other than the
disclosing Party without breach of this Agreement by the receiving Party and
otherwise not in violation of the disclosing Party's rights, (vi) is disclosed
generally to third parties by the disclosing Party without restrictions
similar to those contained in this Agreement, or (vii) is disclosed pursuant
to the order or requirement of a court, administrative agency, or other
governmental body; provided, that the receiving Party shall provide prompt
notice thereof to the disclosing party to enable the disclosing Party to seek
a protective order or otherwise prevent or restrict such disclosure. Each
Party shall be entitled to disclose the existence of this Agreement, but
agrees that the terms and conditions of this Agreement shall be treated as
Confidential Information and shall not be disclosed to any third party;
provided, that each Party may disclose the terms and conditions of this
Agreement (a) as required by any court or other governmental body, (b) as

                  13.4     HEADINGS. The article and section headings used
herein are for reference and convenience only and shall not enter into the
interpretation hereof.

                  13.5     RELATIONSHIP OF PARTIES. The relationship between
the Parties is that of independent contractors and each Party assumes full
responsibility for each of its employees and shall be solely responsible for
the payment of compensation to its personnel. This Agreement does not render
either Party as the agent or legal representative of the other and does not
create a partnership or joint venture between them.

                  13.6     SEVERABILITY. If any provision of this Agreement is
declared or found to be illegal, unenforceable or void, then both parties
shall be relieved of all obligations arising under such provision, but only to
the extent that such provision is illegal, unenforceable or void, it being the
intent and agreement of the parties that this Agreement shall be deemed
amended by modifying such provision to the extent necessary to make it legal
and enforceable while preserving its intent or, if that is not possible, by
substituting therefor another provision that is legal and enforceable and
achieves the same objective. If the remainder of this Agreement shall not be
affected by such declaration or finding and is capable of substantial
performance, then, each provision not so affected shall be enforced to the
extent permitted by law.

                  13.7     PRESS RELEASES. Except to the extent required by
applicable law or as otherwise specified herein, any use by one Party of the
other Party's name, trademarks or service marks in any press releases,
customer lists, marketing materials or other announcements concerning the
matters covered by this Agreement, or for promotional, advertising or other
purposes, shall require the other Party's prior written approval.

                  13.8     WAIVERS. No delay or omission by either party
hereto to exercise any right or power hereunder shall impair such right or
power or be construed to be a waiver thereof. A waiver by either of the
parties hereto of any of the covenants to be performed by the other or any
breach thereof shall not be construed to be a waiver of any succeeding breach
thereof or of any other covenant herein contained. All remedies provided for
in this Agreement shall be cumulative and in addition to and not in lieu of
any other remedies available to either party at law, in equity or otherwise.

                  13.9     FORCE MAJEURE. If the performance of this Agreement
or any obligation hereunder is prevented, restricted or interfered with by
reason of fire or other casualty or accident, acts of God, severe weather
conditions, war or other violence, any law, order, proclamation, regulation,
ordinance, demand or requirement of any governmental agency, or any other act
or condition beyond the

                                      24

<PAGE>

reasonable control of the parties hereto, the party whose performance is so
affected shall be excused from such performance; provided, that if either
party invokes this Section for any consecutive period of thirty (30) days or
longer (or sixty (60) days or longer in any one year period), then the other
party may immediately terminate this Agreement without penalty, upon written
notice to such invoking party.

                  13.10    SURVIVAL OF TERMS. Termination or expiration of
this Agreement for any reason shall not terminate any rights, liabilities or
obligations that have either accrued prior to the effective date of
termination of this Agreement or the representations and warranties,
indemnification provision, limitations of liability or warranty disclaimers,
or any other provisions which the parties have expressly agreed shall survive
any such termination or expiration.

                  13.11    ENTIRE AGREEMENT. This Agreement and each Exhibit
attached hereto, each of which is incorporated herein for all purposes,
constitutes the entire agreement between the parties hereto with respect to
the subject matter hereof, and there are no written or oral representations,
understandings or agreements relative hereto which are not fully expressed
herein. This Agreement and such Exhibits are intended to be the sole and
exclusive statement of the agreement between the parties hereto with respect
to the subject matter hereof and any other terms or conditions included in any
forms utilized or exchanged by the parties hereto shall be of no force or
effect and shall not be incorporated herein or be binding unless expressly
agreed to in writing by both parties hereto. No change, amendment, waiver or
discharge hereof shall be valid unless in writing and signed by an authorized
representative of the Party against which such change, amendment, waiver or
discharge is sought to be enforced.

                  13.12    GOVERNING LAW; JURISDICTION. This Agreement and all
acts and transactions pursuant hereto and the rights and obligations of the
parties hereto shall be governed, construed and interpreted in accordance with
the laws of the State of New York, without giving effect to principles of
conflicts of law. Each of the Parties to this Agreement consents to the
exclusive jurisdiction and venue of the state and federal courts of New York
County, New York.

                  13.13    COUNTERPARTS. This Agreement may be executed in two
or more counterparts, each of which shall be deemed an original and all of

Company shall not be affected by any notice to the contrary.

authorized in writing.

         (b)      LEGENDS.

                  Each Warrant Certificate (and all Warrants issued in exchange

         HEREOF OF THE RESALE RESTRICTIONS SET FORTH IN (A) ABOVE."

         (c)      OBLIGATIONS WITH RESPECT TO TRANSFERS AND EXCHANGES OF
WARRANTS.

                  (i)      To permit registrations of transfers and exchanges,
         the Company shall execute in accordance with the provisions of SECTION
         4 and this SECTION 5, Warrants as required pursuant to the provisions
         of this SECTION 5. Notwithstanding anything to the contrary contained
         herein, the Company shall refuse to register any transfer of the
         Warrants not made in accordance with Regulation S promulgated under the
         Securities Act, pursuant to registration under the Securities Act or
         pursuant to an available exemption from the registration requirements
         of the Securities Act; provided, however, that if a foreign law
         prevents the Company from refusing to register securities transfers,
         the Company shall implement other reasonable measures designed to
         prevent transfers of the Warrants not made in accordance with
         Regulation S, pursuant to registration under the Securities Act or
         pursuant to an available exemption from the registration requirements
         of the Securities Act.

                  (ii)     All Warrants issued upon any registration of transfer
         or exchange of Warrants shall be the valid obligations of the Company,
         entitled to the same benefits under this Warrant Agreement, as the
         Warrants surrendered upon such registration of transfer or exchange.

                  (iii)    Prior to due presentment for registration of transfer
         of any Warrant, the Company may deem and treat the person in whose name
         any Warrant is registered as the absolute owner of such Warrant and the
         Company shall not be affected by notice to the contrary.

                  (iv)     No service charge shall be made to a Holder for any
         registration of transfer or exchange.

         Section 6.        TERMS OF WARRANTS; EXERCISE OF WARRANTS. Subject to
the terms of this Agreement, each Holder shall have the right, which may be
exercised at any time and from time to time, in whole or in part, commencing on
the date hereof and ending at 4:00 p.m., Dallas, Texas, time, on the Expiration
Date, to receive from the Company the number of fully paid and nonassessable
Warrant Shares which the Holder may at the time be entitled to receive on
exercise of such Warrants and payment of the Exercise Price then in effect for
such Warrant Shares; provided, however, that no Holder shall be entitled to
exercise such Holder's Warrants at any time, unless, at the time of exercise,
(i) a registration statement under the Securities Act relating to the Warrant
Shares has been filed with, and declared effective by, the Commission, and no
stop order suspending the effectiveness of such registration statement has been
issued by the Commission or (ii) the issuance of the Warrant Shares is permitted
pursuant to an exemption from the registration requirements of the Securities
Act. Subject to the provisions of the following paragraph of this SECTION 6,
each Warrant not exercised prior to 4:00 p.m., Dallas, Texas, time, on the
Expiration Date

                                        6

<PAGE>

shall become void and all rights thereunder and all rights in respect thereof
under this Agreement shall cease as of such time. No adjustments as to dividends
will be made upon exercise of the Warrants.

         The Company shall use its reasonable efforts to give notice not less
than 90, and not more than 120, days prior to the Expiration Date to the Holders
of all then outstanding Warrants to the effect that the Warrants will terminate
and become void as of 4:00 p.m., Dallas, Texas, time, on the Expiration Date.
Notwithstanding the Company's failure to give such notice, the Expiration Date
shall not be extended and, in no event will Holders be entitled to any damages
or other remedy for the Company's failure to give such notice.

         A Warrant may be exercised upon surrender to the Company of the
certificate or certificates evidencing the Warrant to be exercised with the form
of election to purchase on the reverse thereof properly completed and signed,
and upon payment to the Company of the Exercise Price as adjusted as herein
provided, for each of the Warrant Shares in respect of which such Warrants are
then exercised. Payment of the aggregate Exercise Price shall be made in cash or
by certified or official bank check, payable to the order of the Company. In the
alternative, each Holder may exercise its right to receive Warrant Shares (i) on
a net basis, such that without the exchange of any funds, the Holder receives
that number of Warrant Shares otherwise issuable upon exercise of its Warrants
less that number of Warrant Shares having a current market value equal to the
aggregate Exercise Price that would otherwise have been paid by the Holder for
the Warrant Shares being issued, (ii) by any Holder to whom the Company is
indebted, by tendering indebtedness having an aggregate principal amount, plus
accrued but unpaid interest, if any, thereon, to the date of exercise equal to
the aggregate Exercise Price that would otherwise have been paid by the Holder
for the Warrant Shares being issued, or (iii) by a combination of the procedures
in clauses (i) and (ii). For purposes of the foregoing sentence, "current market
value" of the Warrant Shares shall be as determined in accordance with Section
11(f) hereof. The Company shall notify the Holder in writing of any such
determination of current market value.

         Subject to the provisions of SECTION 7 hereof, upon surrender of
Warrants and payment of the Exercise Price as provided above, the Company shall
promptly transfer to the Holder of such Warrant a certificate or certificates
for the appropriate number of Warrant Shares or other securities or property
(including any money) to which the Holder is entitled, registered or otherwise
placed in, or payable to the order of, such name or names as may be directed in
writing by the Holder, and shall deliver such certificate or certificates
representing the Warrant Shares and any other securities or property (including
any money) to the person or persons entitled to receive the same, together with
an amount in cash in lieu of any fraction of a share as provided in SECTION 13.
Any such certificate or certificates representing the Warrant Shares shall be
deemed to have been issued and any person so designated to be named therein
shall be deemed to have become a Holder of record of such Warrant Shares as of
the later of the date of the surrender of such Warrants and payment of the
Exercise Price.

                                       7

<PAGE>

         The Warrants shall be exercisable commencing on the Issue Date, at the
election of the Holders thereof, either in full or from time to time in part
and, in the event that a certificate evidencing Warrants is exercised in respect
of fewer than all of the Warrant Shares issuable on such exercise at any time
prior to the date of expiration of the Warrants, a new certificate evidencing
the remaining Warrant or Warrants will be issued and delivered pursuant to the
provisions of this SECTION and of SECTION 3 hereof.

         All Warrant Certificates surrendered upon exercise of Warrants shall be
canceled. Such canceled Warrant Certificates shall then be disposed of in
accordance with customary procedures.

         Section 7.        PAYMENT OF TAXES. The Company will pay all
documentary stamp taxes, if any, attributable to the issuance of the Warrant
Certificates or the initial issuance of Warrant Shares upon the exercise of
Warrants; provided, however, that the Company shall not be required to pay any
tax or taxes which may be payable in respect of any transfer involved in the
issue of any certificates for Warrant Shares in a name other than that of the
Holder of a Warrant Certificate surrendered upon the exercise of a Warrant.

         Section 8.        MUTILATED OR MISSING WARRANT CERTIFICATES. In case
any of the Warrant Certificates shall be mutilated, lost, stolen or destroyed,
the Company may in its discretion issue in exchange and substitution for and
upon cancellation of the mutilated Warrant Certificate, or in lieu of and
substitution for the Warrant Certificate lost, stolen or destroyed, a new
Warrant Certificate of like tenor and representing an equivalent number of
Warrants, but only upon receipt of evidence reasonably satisfactory to the
Company of such loss, theft or destruction of such Warrant Certificate and, if
requested, indemnity reasonably satisfactory to them. Applicants for such
substitute Warrant Certificates shall also comply with such other reasonable
regulations and pay such other reasonable charges as the Company may prescribe.

         Section 9.        RESERVATION OF WARRANT SHARES. The Company will at
all times reserve and keep available, free from any preemptive rights, out of
the aggregate of its authorized but unissued Common Stock or its authorized and
issued Common Stock held in its treasury, for the purpose of enabling it to
satisfy any obligation to issue Warrant Shares upon exercise of Warrants, the
maximum number of shares of Common Stock which may then be deliverable upon the
exercise of all outstanding Warrants.

         The transfer agent for the Common Stock (the "TRANSFER AGENT") and
every subsequent transfer agent for any shares of the Company's capital stock
issuable upon the exercise of any of the rights of purchase aforesaid will be
irrevocably authorized and directed at all times to reserve such number of
authorized shares as shall be required for such purpose. The Company will keep a
copy of this Agreement on file with the Transfer Agent and with every subsequent
transfer agent for any shares of the Company's capital stock issuable upon the
exercise of the rights of purchase represented by the Warrants. The Company will
supply such Transfer Agent with duly executed certificates for such purposes and
will provide or otherwise make available any cash which may be payable as
provided in SECTION 13. The Company will furnish such Transfer Agent a copy of
all notices of

                                        8
<PAGE>

adjustments and certificates related thereto, transmitted to each Holder of the
Warrants pursuant to SECTION 14 hereof.

         Before taking any action which would cause an adjustment pursuant to
SECTION 11 hereof that would reduce the Exercise Price below the then par
value (if any) of the Warrant Shares, the Company will take any corporate
action which may, in the opinion of its counsel, be necessary in order that
the Company may validly and legally issue fully paid and nonassessable
Warrant Shares at the Exercise Price as so adjusted.

         The Company covenants that all Warrant Shares which may be issued
upon exercise of Warrants in accordance with the terms of this Agreement
(including the payment of the Exercise Price) will, upon issue, be duly and
validly issued, fully paid, nonassessable, and free of preemptive rights and
Liens.

         Section 10.       Intentionally Omitted.

         Section 11.       ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT
SHARES ISSUABLE. The number and kind of shares purchasable upon the exercise of
Warrants and the Exercise Price shall be subject to adjustment from time to time
(as set forth in the notices required by SECTION 14 hereof) as follows:

         (a)      STOCK SPLITS, COMBINATIONS, ETC. In case the Company shall
hereafter (A) pay a dividend or make a distribution on its Common Stock in
shares of its capital stock (whether shares of Common Stock or of capital stock
of any other class), (B) subdivide its outstanding shares of Common Stock, (C)
combine its outstanding shares of Common Stock into a smaller number of shares,
or (D) issue by reclassification of its shares of Common Stock any shares of
capital stock of the Company, the Exercise Price in effect and the number of
Warrant Shares issuable upon exercise of each Warrant immediately prior to such
action shall be adjusted so that the Holder of any Warrant thereafter exercised
shall be entitled to receive the number of shares of capital stock of the
Company which such Holder would have owned immediately following such action had
such Warrant been exercised immediately prior thereto. Any adjustment made
pursuant to this paragraph shall become effective immediately after the record
date in the case of a dividend and shall become effective immediately after the
effective date in the case of a subdivision, combination or reclassification.
If, as a result of an adjustment made pursuant to this paragraph, the Holder of
any Warrant thereafter exercised shall become entitled to receive shares of two
or more classes of capital stock of the Company, the Board of Directors of the
Company (whose determination shall be conclusive and evidenced by a Board
resolution) shall determine the allocation of the adjusted Exercise Price
between or among shares of such classes of capital stock.

         (b)      RECLASSIFICATION, COMBINATIONS, MERGERS, ETC. In case of any
reclassification or change of outstanding shares of Common Stock issuable upon
exercise of the Warrants (other than as set forth in PARAGRAPH (a) above and
other than a change in par value, or from par value to no par value, or from no
par value to par value or as a result of a subdivision or combination), or in
case

                                        9
<PAGE>

of any consolidation or merger of the Company with or into another corporation
(other than a merger in which the Company is the continuing corporation and
which does not result in any reclassification or change of the then outstanding
shares of Common Stock or other capital stock issuable upon exercise of the
Warrants) or in case of any sale or conveyance to another corporation of all or
substantially all of the assets of the Company, then, as a condition of such
reclassification, change, consolidation, merger, sale or conveyance, the Company
or such a successor or purchasing corporation, as the case may be, shall
forthwith make lawful and adequate provision whereby the Holder of each Warrant
then outstanding shall have the right thereafter to receive on exercise of such
Warrant the kind and amount of shares of stock and other securities and property
receivable upon such reclassification, change, consolidation, merger, sale or
conveyance by a Holder of the number of shares of Common Stock issuable upon
exercise of such Warrant immediately prior to such reclassification, change,
consolidation, merger, sale or conveyance and enter into a supplemental warrant
agreement so providing. Such provisions shall include provision for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this SECTION 11. If the issuer of securities deliverable upon
exercise of Warrants under the supplemental warrant agreement is an affiliate of
the formed, surviving or transferee corporation, that issuer shall join in the
supplemental warrant agreement. The Company shall not effect any such
reclassification, consolidation, merger, conveyance, transfer, dissolution,
liquidation or winding up or change of control unless, prior to the consummation
thereof, the successor corporation (if other than the Company) resulting from
such reclassification, consolidation, merger, conveyance, transfer, dissolution,
liquidation or winding up or change of control, shall assume, by written
instrument executed and delivered to the Holder, the obligation to deliver to
the Holder such shares of stock, securities or assets, which, in accordance with
the foregoing provisions, such Holder shall be entitled to purchase. The above
provisions of this PARAGRAPH (b) shall similarly apply to successive
reclassifications and changes of shares of Common Stock and to successive
consolidations, mergers, sales or conveyances.

         (c)      ISSUANCE OF ADDITIONAL SHARES OF COMMON STOCK. In the event
the Company shall, at any time or from time to time after the date hereof,
issue, sell, distribute or otherwise grant in any manner (including by
assumption) any Additional Shares of Common Stock without consideration or for a
price per share less than either (i) the Exercise Price, as adjusted, or (ii)
the current market price per share (as determined in accordance with Section
11(f) hereof) of Common Stock on the date of the issuance, sale, distribution or
granting of such Additional Shares of Common Stock, then, effective upon such
issuance or sale, (I) the Exercise Price shall be reduced to the price
(calculated to the nearest 1/1,000 of one cent) determined by multiplying the
Exercise Price in effect immediately prior to such issuance or sale by a
fraction, the numerator of which shall be the sum of (i) the number of shares of
Common Stock outstanding (exclusive of any treasury shares) immediately prior to
such issuance or sale multiplied by the greater of the Exercise Price or the
current market price per share of Common Stock on the date of such issuance or
sale plus (ii) the consideration, if any, received by the Company in respect of
such issuance or sale, and the denominator of which shall be the product of (A)
the total number of shares of Common Stock outstanding (exclusive of any
treasury shares) immediately after such issuance or sale multiplied by (B) the
greater of the Exercise Price or the current market price per share of Common
Stock on the

                                       10
<PAGE>

record date for such issuance or sale and (II) the number of shares of Common
Stock purchasable upon the exercise of each Warrant shall be increased to a
number determined by multiplying the number of shares of Common Stock so
purchasable immediately prior to the record date for such issuance or sale by a
fraction, the numerator of which shall be the Exercise Price in effect
immediately prior to the adjustment required by clause (I) of this sentence and
the denominator of which shall be the Exercise Price in effect immediately after
such adjustment.

         (d)      ISSUANCE OF OPTIONS OR CONVERTIBLE SECURITIES. In the event
the Company shall, at any time or from time to time after the date hereof,
issue, sell, distribute or otherwise grant in any manner (including by
assumption) any rights to subscribe for or to purchase, or any warrants or
options for the purchase of, Common Stock (other than shares pursuant to any
stock option plan, stock purchase plan, stock award plan or stock incentive plan
of the Company in any amount not more than fifteen percent (15%) of the fully
diluted capital stock of the Company) or any stock or securities convertible
into or exchangeable for Common Stock (any such rights, warrants or options
(other than any other warrants issued to Holder) being herein called "OPTIONS"
and any such convertible or exchangeable stock or securities (other than the
issuance of Series B Preferred or Series C Preferred pursuant to the Series B
Preferred Purchase Agreement and the Series C Preferred Purchase Agreement)
being herein called "CONVERTIBLE SECURITIES") or any Convertible Securities
(other than upon exercise of any Option), whether or not such Options or the
rights to convert or exchange such Convertible Securities are immediately
exercisable, and if the price per share at which Common Stock is issuable upon
the exercise of such Options or upon the conversion or exchange of such
Convertible Securities (determined by dividing (i) the aggregate amount, if any,
received or receivable by the Company as consideration for the issuance, sale,
distribution or granting of such Options or any such Convertible Security, plus
the minimum aggregate amount of additional consideration, if any, payable to the
Company upon the exercise of all such Options or upon conversion or exchange of
all such Convertible Securities, plus, in the case of Options to acquire
Convertible Securities, the minimum aggregate amount of additional
consideration, if any, payable upon the conversion or exchange of all such
Convertible Securities, by (ii) the total maximum number of shares of Common
Stock issuable upon the exercise of all such Options or upon the conversion or
exchange of all such Convertible Securities or upon the conversion or exchange
of all Convertible Securities issuable upon the exercise of all such Options)
shall be less than either (i) the Exercise Price, as adjusted, or (ii) the
current market price (as determined in accordance with Section 11(f) hereof) per
share of Common Stock on the date for the issuance, sale, distribution or
granting of such Options or Convertible Securities (any such event being herein
called a "DISTRIBUTION"), then, effective upon such Distribution, (I) the
Exercise Price shall be reduced to the price (calculated to the nearest 1/1,000
of one cent) determined by multiplying the Exercise Price in effect immediately
prior to such Distribution by a fraction, the numerator of which shall be the
sum of (i) the number of shares of Common Stock outstanding (exclusive of any
treasury shares) immediately prior to such Distribution multiplied by the
greater of the Exercise Price or the current market price per share of Common
Stock on the date of such Distribution plus (ii) the consideration, if any,
received by the Company in respect of such Distribution, and the denominator of
which shall be the product of (A) the total number of shares of Common Stock
outstanding (exclusive of any treasury shares) immediately after such
Distribution multiplied by (B) the greater of the Exercise Price or the current

                                       11
<PAGE>

market price per share of Common Stock on the record date for such
Distribution and (II) the number of shares of Common Stock purchasable upon
the exercise of each Warrant shall be increased to a number determined by
multiplying the number of shares of Common Stock so purchasable immediately
prior to the record date for such Distribution by a fraction, the numerator
of which shall be the Exercise Price in effect immediately prior to the
adjustment required by clause (I) of this sentence and the denominator of
which shall be the Exercise Price in effect immediately after such
adjustment. For purposes of the foregoing, the total maximum number of shares
of Common Stock issuable upon exercise of all such Options or upon conversion
or exchange of all such Convertible Securities or upon the conversion or
exchange of the total maximum amount of the Convertible Securities issuable
upon the exercise of all such Options shall be deemed to have been issued as
of the date of such Distribution and thereafter shall be deemed to be
outstanding and the Company shall be deemed to have received as consideration
therefor such price per share, determined as provided above. Except as
provided in PARAGRAPHS (j) AND (k) below, no additional adjustment of the
Exercise Price shall be made upon the actual exercise of such Options or upon
conversion or exchange of the Convertible Securities or upon the conversion
or exchange of the Convertible Securities issuable upon the exercise of such
Options.

         (e)      DIVIDENDS AND DISTRIBUTIONS. In the event the Company
shall, at any time or from time to time after the date hereof, distribute to
all the holders of Common Stock any dividend or other distribution of cash,
evidences of its indebtedness, other securities or other properties or assets
(in each case other than (i) dividends payable in Common Stock, Options or
Convertible Securities and (ii) any cash dividend that, when added to all
other cash dividends paid with respect to Common Stock in the one year prior
to the declaration date of such dividend (excluding any such other dividend
included in a previous adjustment of the Exercise Price pursuant to this
PARAGRAPH (e) and excluding any cash dividends or other cash distributions
from current or retained earnings), does not exceed 5% of the current market
price per share of Common Stock on such declaration date), or any options,
warrants or other rights to subscribe for or purchase any of the foregoing,
then (A) the Exercise Price shall be decreased to a price determined by
multiplying the Exercise Price then in effect by a fraction, the numerator of
which shall be the current market price per share of Common Stock on the
record date for such distribution less the sum of (X) the cash portion, if
any, of such distribution per share of Common Stock outstanding (exclusive of
any treasury shares) on the record date for such distribution plus (Y) the
then current market value (as determined in accordance with Section 11(f)
hereof) per share of Common Stock outstanding (exclusive of any treasury
shares) on the record date for such distribution of that portion, if any, of
such distribution consisting of evidences of indebtedness, other securities,
properties, assets, options, warrants or subscription or purchase rights, and
the denominator of which shall be such current market price per share of
Common Stock and (B) the number of shares of Common Stock purchasable upon
the exercise of each Warrant shall be increased to a number determined by
multiplying the number of shares of Common Stock so purchasable immediately
prior to the record date for such distribution by a fraction, the numerator
of which shall be the Exercise Price in effect immediately prior to the
adjustment required by clause (A) of this sentence and the denominator of
which shall be the Exercise Price in effect immediately after such
adjustment. The adjustments required by this

                                       12
<PAGE>

PARAGRAPH (e) shall be made whenever any such distribution occurs retroactive
to the record date for the determination of stockholders entitled to receive
such distribution.

         (f)      CURRENT MARKET PRICE. For the purpose of any computation of
current market price under this Agreement, the current market price per share
of Common Stock at any date shall be the daily closing price the last full
trading day on the exchange or market specified in the second succeeding
sentence prior to the Time of Determination (as defined below). The term
"TIME OF DETERMINATION" as used herein shall be the time and date of the
earlier to occur of (A) the date as of which the current market price is to
be computed and (B) the last full trading day on such exchange or market
before the commencement of "ex-dividend" trading in the Common Stock relating
to the event giving rise to the adjustment required by PARAGRAPH (a), (b),
(c), (d) OR (e) above. The closing price for any day shall be the last
reported sale price regular way or, in case no such reported sale takes place
on such day, the average of the closing bid and asked prices regular way for
such day, in each case (1) on the principal national securities exchange on
which the shares of Common Stock are listed or to which such shares are
admitted to trading or (2) if the Common Stock is not listed or admitted to
trading on a national securities exchange, in the over-the-counter market as
reported by Nasdaq National or SmallCap Markets or any comparable system or
(3) if the Common Stock is not listed on Nasdaq National or SmallCap Markets
or a comparable system but a public market for the Common Stock exists, as
furnished by two members of the NASD selected from time to time in good faith
by the Board of Directors of the Company for that purpose. In the absence of
all of the foregoing, or if for any other reason the current market price per
share cannot be determined pursuant to the foregoing provisions of this
PARAGRAPH (f), the current market price per share shall be the fair market
value thereof as determined in good faith by the Board of Directors of the
Company and evidenced by a resolution of such Board, subject to the following
dispute resolution right of the Holders of the Warrants. In the event that
Holders of a majority of the Warrants dispute the determination of the Board
of Directors, such Holders shall notify the Company and the current market
price shall be determined in a reasonably prompt manner as follows:

         (1)      The Company and Holders of a majority of the Warrants shall
         each appoint an independent, experienced appraiser who is a member of a
         recognized professional association of business appraisers. The two
         appraisers shall determine the value of shares of Common Stock at the
         relevant date, assuming a sale between a willing buyer and a willing
         seller, both of whom have full knowledge of the financial and other
         affairs of the Company, and neither of whom is under any compulsion to
         sell or to buy.

         (2)      If the higher of the two appraisals is not more than 20% more
         than the lower of the appraisals, the current market price per share
         shall be the average of the two appraisals. If the higher of the two
         appraisals is 20% or more than the lower of the two appraisals, then a
         third appraiser shall be appointed by the two appraisers, and if they
         cannot agree on a third appraiser, the American Arbitration Association
         shall appoint the third appraiser. The third appraiser, regardless of
         who appoints him or her, shall have the same qualifications as the
         first two appraisers.

                                       13

<PAGE>

         (3)      The current market price per share after the appointment of
         the third appraiser shall be the average of the two appraisals that are
         closest in value to each other.

         (4)      The fees and expenses of the appraisers shall be paid one-half
         by the Company and one-half by the Holders.

         (g)      CERTAIN DISTRIBUTIONS. If the Company shall pay a dividend or
make any other distribution payable in Options or Convertible Securities, then,
for purposes of PARAGRAPH (d) above, such Options or Convertible Securities
shall be deemed to have been initially issued or sold on such date without
consideration.

         (h)      CONSIDERATION RECEIVED. If any shares of Common Stock, Options
or Convertible Securities shall be issued, sold or distributed for a
consideration other than cash, the amount of the consideration other than cash
received by the Company in respect thereof shall be deemed to be the then
current market value of such consideration (as determined in accordance with
Section 11(f) hereof). If any Options shall be issued in connection with the
issuance and sale of other securities of the Company, together comprising one
integral transaction in which no specific consideration is allocated to such
Options by the parties thereto, such Options shall be deemed to have been issued
without consideration; provided, however, that if such Options have an exercise
price equal to or greater than the current market price of the Common Stock on
the date of issuance of such Options, then such Options shall be deemed to have
been issued for consideration equal to such exercise price.

         (i)      DEFERRAL OF CERTAIN ADJUSTMENTS. No adjustment to the Exercise
Price (including the related adjustment to the number of shares of Common Stock
purchasable upon the exercise of each Warrant) shall be required hereunder
unless such adjustment, together with other adjustments carried forward as
provided below, would result in an increase or decrease of at least one percent
of the Exercise Price; provided that any adjustments which by reason of this
PARAGRAPH (i) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. No adjustment need be made for a
change in the par value of the Common Stock. All calculations under this SECTION
shall be made to the nearest 1/1,000 of one cent or to the nearest 1/1000 of a
share, as the case may be.

         (j)      CHANGES IN OPTIONS AND CONVERTIBLE SECURITIES. If the exercise
price provided for in any Options referred to in PARAGRAPH (d) above, the
additional consideration, if any, payable upon the conversion or exchange of any
Convertible Securities referred to in PARAGRAPH (d) OR (e) above, or the rate at
which any Convertible Securities referred to in PARAGRAPH (d) OR (e) above are
convertible into or exchangeable for Common Stock shall change at any time
(other than under or by reason of provisions designed to protect against
dilution upon an event which results in a related adjustment pursuant to this
SECTION 11), the Exercise Price then in effect and the number of shares of
Common Stock purchasable upon the exercise of each Warrant shall forthwith be
readjusted (effective only with respect to any exercise of any Warrant after
such readjustment) to the Exercise Price and number of shares of Common Stock so
purchasable that would then be in effect had the adjustment made upon the
issuance, sale, distribution or granting of such Options or Convertible
Securities been

                                       14

<PAGE>

made based upon such changed purchase price, additional consideration or
conversion rate, as the case may be, but only with respect to such Options
and Convertible Securities as then remain outstanding.

         (k)      EXPIRATION OF OPTIONS AND CONVERTIBLE SECURITIES. If, at any
time after any adjustment to the number of shares of Common Stock purchasable
upon the exercise of each Warrant shall have been made pursuant to PARAGRAPH
(d), (e) OR (j) above or this PARAGRAPH (k), any Options or Convertible
Securities shall have expired unexercised, the number of such shares so
purchasable shall, upon such expiration, be readjusted and shall thereafter be
such as they would have been had they been originally adjusted (or had the
original adjustment not been required, as the case may be) as if (i) the only
shares of Common Stock deemed to have been issued in connection with such
Options or Convertible Securities were the shares of Common Stock, if any,
actually issued or sold upon the exercise of such Options or Convertible
Securities and (ii) such shares of Common Stock, if any, were issued or sold for
the consideration actually received by the Company upon such exercise plus the
aggregate consideration, if any, actually received by the Company for the
issuance, sale, distribution or granting of all such Options or Convertible
Securities, whether or not exercised; provided that no such readjustment shall
have the effect of decreasing the number of such shares so purchasable by an
amount (calculated by adjusting such decrease to account for all other
adjustments made pursuant to this SECTION 11 following the date of the original
adjustment referred to above) in excess of the amount of the adjustment
initially made in respect of the issuance, sale, distribution or granting of
such Options or Convertible Securities.

         (l)      OTHER ADJUSTMENTS. In the event that at any time, as a result
of an adjustment made pursuant to this SECTION 11, the Holders shall become
entitled to receive any securities of the Company other than shares of Common
Stock, thereafter the number of such other securities so receivable upon
exercise of the Warrants and the Exercise Price applicable to such exercise
shall be subject to adjustment from time to time in a manner and on terms as
nearly equivalent as practicable to the provisions with respect to the shares of
Common Stock contained in this SECTION 11.

         (m)      IPO VALUATION. If the aggregate market value of the shares of
Common Stock of the Company outstanding immediately after the closing of the
Company's initial public offering, determined utilizing the per share offering
price in such offering (before deducting underwriting discounts and
commissions), is less than $750,000,000, then the aggregate Exercise Price for
the Warrants shall be reduced so that it is equal to five percent (5%) of such
aggregate market value, and the initial Exercise Price per share shall be equal
to the result of the aggregate Exercise Price divided by the aggregate number of
shares of Common Stock issuable upon the exercise of the Warrants, issued in
accordance with Section 2(b) hereof (subject to adjustment from time to time
pursuant to Section 11 hereof). Such initial Exercise Price, as determined
pursuant to this Section 11(m) shall be further adjusted by any and all
adjustments which were, or should have been, made pursuant to this Section 11
during the period from the date of this Agreement through the Company's initial
public offering.

                                       15

<PAGE>

         Section 12.       STATEMENT ON WARRANTS.  Irrespective of any
adjustment in the number or kind of shares issuable upon the exercise of the
Warrants or the Exercise Price, Warrants theretofore or thereafter issued may
continue to express the same number and kind of shares as are stated in the
Warrants initially issuable pursuant to this Agreement.

         Section 13.       FRACTIONAL INTEREST. The Company shall not be
required to issue fractional shares of Common Stock on the exercise of Warrants.
If more than one Warrant shall be presented for exercise in full at the same
time by the same Holder, the number of full shares of Common Stock which shall
be issuable upon such exercise shall be computed on the basis of the aggregate
number of shares of Common Stock acquirable on exercise of the Warrants so
presented. If any fraction of a share of Common Stock would, except for the
provisions of this SECTION, be issuable on the exercise of any Warrant (or
specified portion thereof), the Company shall direct the Transfer Agent to pay
an amount in cash calculated by it equal to (i) the then current market price
per share multiplied by such fraction computed to the nearest whole cent, less
(ii) an amount equal to the Exercise Price multiplied by such fraction computed
to the nearest whole cent. The Holders, by their acceptance of the Warrant
Certificates, expressly waive any and all rights to receive any fraction of a
share of Common Stock or a stock certificate representing a fraction of a share
of Common Stock.

         Section 14.       NOTICES TO HOLDERS. Upon any adjustment of the
Exercise Price pursuant to SECTION 11, the Company shall promptly thereafter
cause to be given to each of the registered Holders by first-class mail, postage
prepaid, a certificate executed by the Chief Financial Officer of the Company
setting forth the Exercise Price after such adjustment and setting forth in
reasonable detail the method of calculation and the facts upon which such
calculations are based and setting forth the number of Warrant Shares (or
portion thereof) issuable after such adjustment in the Exercise Price, upon
exercise of a Warrant and payment of the adjusted Exercise Price, which
certificate shall be conclusive evidence, absent manifest error, of the
correctness of the matters set forth therein.

         In case:

                  (a)      the Company shall authorize the issuance to all
         holders of shares of Common Stock of rights, options or warrants to
         subscribe for or purchase shares of Common Stock or of any other
         subscription rights or warrants; or

                  (b)      the Company shall authorize the distribution to all
         holders of shares of Common Stock of evidences of its indebtedness or
         assets (other than cash dividends or cash distributions payable out of
         consolidated earnings or earned surplus or dividends payable in shares
         of Common Stock or distributions referred to in SECTION 11 hereof); or

                  (c)      of any consolidation or merger to which the Company
         is a party for which approval of any shareholders of the Company is
         required and following which the shareholders of the Company before
         such consolidation or merger no longer hold at least

                                       16

<PAGE>

         50% of the outstanding capital stock of the Company following the
         merger or consolidation, or of the conveyance or transfer of all or
         substantially all of the properties and assets of the Company, or of
         any reclassification or change of Common Stock issuable upon exercise
         of the Warrants (other than a change in par value, or from par value to
         no par value, or from no par value to par value, or as a result of a
         subdivision or combination), or a tender offer or exchange offer for
         shares of Common Stock, or other transaction that would result in a
         change in control; or

                  (d)      of the voluntary or involuntary dissolution,
         liquidation or winding up of the Company; or

                  (e)      the Company proposes to take any other action that
         would require an adjustment of the Exercise Price or the number of
         Warrant Shares pursuant to SECTION 11; then the Company shall cause to
         be given to each of the registered Holders of the Warrants at such
         Holder's address appearing on the Warrant register, at least 20 days
         (or 10 days in any case specified in clauses (a) or (b) above) prior to
         the applicable record date hereinafter specified, or promptly in the
         case of events for which there is no record date, by first-class mail,
         postage prepaid, a written notice stating (i) the date as of which the
         holders of record of shares of Common Stock to be entitled to receive
         any such rights, options, warrants or distribution are to be
         determined, or (ii) the initial expiration date set forth in any tender
         offer or exchange offer for shares of Common Stock, or (iii) the date
         on which any such reclassification, consolidation, merger, conveyance,
         transfer, dissolution, liquidation or winding up or change of control
         is expected to become effective or consummated, and the date as of
         which it is expected that holders of record of shares of Common Stock
         shall be entitled to exchange such shares for securities or other
         property, if any, deliverable upon such reclassification,
         consolidation, merger, conveyance, transfer, dissolution, liquidation
         or winding up or change of control. The failure to give the notice
         required by this SECTION 14 or any defect therein shall not affect the
         legality or validity of any distribution, right, option, warrant,
         consolidation, merger, conveyance, transfer, dissolution, liquidation
         or winding up, or change of control or the vote upon any action.
         Nothing contained in this Agreement or in any of the Warrant
         Certificates shall be construed as conferring upon the Holders thereof
         the right to vote or to consent or to receive notice as shareholders in
         respect of the meetings of shareholders or the election of Directors of
         the Company or any other matter, or any rights whatsoever as
         shareholders of the Company.

         Section 15.       REGISTRATION. The Company acknowledge that Holders of
Warrants shall have the registration rights set forth in the First Amended and

they were so subject) required to file with the Commission pursuant to such

may from time to time supplement or amend this Agreement without the approval of
any Holders of Warrants in order to cure any ambiguity or to correct or

applicable to the Company or any of its Subsidiaries or by which any property
or asset of the Company or any Subsidiary is bound or affected, or (d) result
in the creation of any lien or encumbrance upon any of their assets.

         Section 24.       REPRESENTATIONS AND WARRANTIES OF THE HOLDER.
Holder represents and warrants to the Company as follows:

         (a)      CORPORATE EXISTENCE. The Holder is an entity duly
organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation.

         (b)      ACKNOWLEDGMENT OF RISKS. The Holder has carefully reviewed
and understands the risks of, and other considerations relating to, this
Agreement, the Warrants and the Warrant Shares.

         (c)      ACQUISITION OF WARRANT SHARES. Upon exercise of the
Warrants, Holder will acquire the Warrant Shares for its own account or for
one or more separate accounts maintained by it and without the view to the
distribution thereof within the meaning of the Securities Act or with any
present intention of distributing or selling the Warrant Shares except in
compliance with the Securities Act.

         (d)      NO REGISTRATION. The Holder understands that (i) the
Warrants and the Warrant Shares (A) have not been registered under the
Securities Act or any state securities laws, (B) will be issued in reliance
upon an exemption from the registration and prospectus delivery requirements
of the Securities Act, (C) will be issued in reliance upon exemptions from
the registration and prospectus delivery requirements of state securities
laws, (ii) there is not currently any trading market for the Warrants or the
Warrant Shares and there can be no assurances that the Warrants and the
Warrant Shares will be listed on any exchange or quoted on any quotation
system, and (iii) the Holder must therefore bear the economic risk of such
investment indefinitely unless a subsequent disposition thereof is registered
under the Securities Act and applicable state securities laws or is exempt
therefrom. The Holder further understands that such exemption depends upon,
among other things, the bona fide nature of the investment intent of the
Holder expressed herein. Pursuant to the foregoing, the Holder acknowledges
that any certificate representing any Warrant Shares acquired by the Holder
shall bear the restrictive legends set forth in Section 5(b).

         (e)      INVESTMENT EXPERIENCE. The Holder, together with its
advisors, has knowledge, skill and experience in financial, business and
investment matters relating to an investment of this type and is capable of
evaluating the merits and risks of such investment and protecting the
Holder's interest in connection with the acquisition of the Warrants and any
Warrant Shares. The Holder understands that the acquisition of the Warrants
and any Warrant Shares is a speculative investment and involves substantial
risks and that the Holder could lose the Holder's entire investment in the
Warrants and any Warrant Shares. To the extent deemed necessary by the
Holder, the Holder has retained, at its own expense, and has relied upon
appropriate professional advice regarding the investment, tax and legal
merits and consequences of purchasing and owning the Warrants and any Warrant
Shares. The Holder has the ability to bear the economic risks of investment
in the Company, including a complete loss of the investment, and the Holder
has no need for liquidity in such investment.

         (f)      STATUS AS ACCREDITED INVESTOR. The Holder is an "Accredited
Investor" within the meaning of Rule 501 of Regulation D, promulgated by the
United States Securities and Exchange Commission pursuant to the Securities
Act.

         Section 25.       COUNTERPARTS.  This Agreement may be executed in
any number of counterparts and each of such counterparts shall for all
purposes be deemed to be an original, and all such counterparts shall
together constitute but one and the same instrument.
