                          Common Stock Purchase Warrant

                             Expiring April 30, 2003

                                                           Stamford, Connecticut

                                                           ______________, 1999


         SMARTSERV ONLINE, INC., a Delaware corporation (the "Company"), for
value received, hereby certifies that Data Transmission Network Corporation, or
registered assigns, is entitled to purchase from the Company 300,000 duly
authorized, validly issued, fully paid and nonassessable shares of Common Stock,
par value $.01 per share, of the Company (the "Common Stock") at the purchase
price per share of $8.60, at any time or from time to time prior to 3 P.M., New
York City time, on the earlier of (i) April 30, 2003 or (ii) the date one year
after the Current Market Price of the Common Stock (determined without
consideration of clause (z) of the definition of Market Price) reaches $8.60 per
share, all subject to the terms, conditions and adjustments set forth below in
this Warrant.

         This Warrant is issued pursuant to that certain Agreement dated May 1,
1999, between the Company and Data Transmission Network Corporation (the "DTN
Agreement"). Certain capitalized terms used in this Warrant are defined in
Section 14. If a capitalized term used in this Warrant is not defined in Section
14, or elsewhere in this Warrant, such term shall have the meaning given such
term in the DTN Agreement.

               1. Exercise of Warrant.

                  1.1. Manner of Exercise.

         (a) This Warrant may be exercised by the holder hereof, in whole or in
part, during normal business hours on any Business Day prior to the expiration
of this Warrant by surrender of this Warrant, with the form of subscription at
the end hereof (or a facsimile thereof) duly executed by such holder, to the
Company at its principal office (or, if such exercise shall be in connection
with an underwritten Public Offering of shares of Common Stock (or Other
Securities) subject to this Warrant, at the location at which the Company shall
have agreed to



deliver the shares of Common Stock (or Other Securities) subject to such
offering), accompanied by payment, in cash or by certified or official bank
check payable to the order of the Company, in the amount obtained by multiplying
(a) the number of shares of Common Stock (without giving effect to any
adjustment therein) designated in such form of subscription by (b) the Warrant
Price, and such holder shall thereupon be entitled to receive the number of duly
authorized, validly issued, fully paid and nonassessable shares of Common Stock
(or Other Securities) determined as provided in Sections 2 through 4.

         (b) Holder may elect in writing delivered to the Company as provided
above to receive, without payment of additional consideration, shares of Common
Stock equal to the value of this Warrant or any portion hereof by the surrender
of this Warrant or such portion to the Company at its principal office.
Thereupon, the Company shall issue to such holder such number of fully paid and
nonassessable shares of Common Stock as is computed using the following formula:

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

         where X = the number of shares to be issued to such holder pursuant to
this subsection 1.1(b).

                  Y=       the number of shares covered by this Warrant in
                           respect of which the net issue election is made
                           pursuant to this subsection 1.1(b).

                  A=       the Market Price of one share of Common Stock as at
                           the time the net issue election is made pursuant to
                           this subsection 1.1(b).

                  B=       the Warrant Price in effect under this Warrant at
                           the time the net issue election is made pursuant to
                           this subsection 1.1(b).

                  1.2. When Exercise Deemed Effected. Each exercise of this
Warrant shall be deemed to have been effected immediately prior to the close of
business on the Business Day on which this Warrant shall have been surrendered
to the Company as provided in Section 1.1, and at such time the person or
persons in whose name or names any certificate or certificates for shares of
Common Stock (or Other Securities) shall be issuable upon such exercise as
provided in Section 1.3 shall be deemed to have become the holder or holders of
record thereof.

                  1.3. Delivery of Stock Certificates, Etc. As soon as
practicable after the exercise of this Warrant, in whole or in part, and in any
event within ten (10) Business Days thereafter (unless such exercise shall be in
connection with an underwritten Public Offering of shares of Common Stock (or
Other Securities) subject to this Warrant, in which event concurrently with such
exercise), the Company at its expense (including the payment by it of any taxes
(other than transfer taxes) payable by the Company) will cause to be issued in
the name of and delivered to the holder hereof or, subject to Section 8, as such
holder (upon payment by such holder of any applicable transfer taxes) may
direct,

                                       2


                  (a) a certificate or certificates for the number of duly
         authorized, validly issued, fully paid and nonassessable shares of
         Common Stock (or Other Securities) to which such holder shall be
         entitled upon such exercise plus, in lieu of any fractional share to
         which such holder would otherwise be entitled, cash in an amount equal
         to the same fraction of the Market Price per share of such Common Stock
         (or Other Securities) on the Business Day next preceding the date of
         such exercise, and

                  (b) in case such exercise is in part only, a new Warrant of
         like tenor, calling in the aggregate on the face thereof for the number
         of shares of Common Stock equal (without giving effect to any
         adjustment therein) to the number of such shares called for on the face
         of this Warrant minus the number of such shares designated by the
         holder upon such exercise as provided in Section 1.1.

                  1.4. Company to Reaffirm Obligations. The Company will, at the
time of or at any time after each exercise of this Warrant, upon the request of
the holder hereof or of any shares of Common Stock (or Other Securities) issued
upon such exercise, acknowledge in writing its continuing obligation to afford
to such holder all rights (including, without limitation, any right of
registration of any shares of Common Stock (or Other Securities) issuable upon
exercise of this Warrant pursuant to Section 9) to which such holder shall
continue to be entitled after such exercise in accordance with the terms of this
Warrant, provided that if any such holder shall fail to make any such request,
the failure shall not affect the continuing obligation of the Company to afford
such rights to such holder.

               2. Adjustments.


                  2.1. Number of Shares; Warrant Price. The number of shares of
Common Stock which the holder of this Warrant shall be entitled to receive upon
each exercise hereof shall be determined by multiplying the number of shares of
Common Stock which would otherwise (but for the provisions of this Section 2) be
issuable upon such exercise, as designated by the holder hereof pursuant to
Section 1.1, by a fraction of which (a) the numerator is $8.60 and (ii) the
denominator is the Warrant Price in effect on the date of such exercise. The
"Warrant Price" shall initially be $8.60 per share, and shall be adjusted and
readjusted from time to time as provided in this Section 2 and, as so adjusted
or readjusted, shall remain in effect until a further adjustment or readjustment
thereof is required by this Section 2.

                  2.2. Adjustment of Warrant Price.

                     2.2.1. Issuance of Additional Shares of Common Stock. In
case the Company, at any time or from time to time after April 30, 1999 (the
"Initial Date"), shall issue or sell Additional Shares of Common Stock
(including Additional Shares of Common Stock deemed to be issued pursuant to
Section 2.3 or 2.4) without consideration or for a consideration per share less
than the Base Price in effect, in each case, on the date of and immediately
prior to such issue or sale, then, and in each such case, subject to Section
2.8, such Warrant Price shall be reduced, concurrently with such issue or sale,
to a price (calculated to the nearest .001 of a cent) determined by multiplying
such Warrant Price by a fraction,

                                       3


                  (a) the numerator of which shall be (i) the number of shares
         of Common Stock outstanding immediately prior to such issue or sale
         plus (ii) the number of shares of Common Stock which the aggregate
         consideration received by the Company for the total number of such
         Additional Shares of Common Stock so issued or sold would purchase at
         the Base Price, and

                  (b) the denominator of which shall be the number of shares of
         Common Stock outstanding immediately after such issue or sale,

provided that, for the purposes of this Section 2.2.1 (x) immediately after any
Additional Shares of Common Stock are deemed to have been issued pursuant to
Section 2.3 or 2.4, such Additional Shares shall be deemed to be outstanding,
and (y) treasury shares shall not be deemed to be outstanding.

                     2.2.2. Extraordinary Dividends and Distributions. In case
the Company at any time or from time to time after the Initial Date shall
declare, order, pay or make a dividend or other distribution (including, without
limitation, any distribution of other or additional stock or other securities or
property or options by way of dividend or spin-off, reclassification,
recapitalization or similar corporate rearrangement) on any Common Stock, other
than (a) a dividend payable in Additional Shares of Common Stock or in Options
for Common Stock or (b) a dividend payable in cash, then, and in each such case,
subject to Section 2.8, the Warrant Price in effect immediately prior to the
close of business on the record date fixed for the determination of holders of
any class of securities entitled to receive such dividend or distribution shall
be reduced, effective as of the close of business on such record date, to a
price (calculated to the nearest .001 of a cent) determined by multiplying such
Warrant Price by a fraction,

                  (x) the numerator of which shall be the Current Market Price
         in effect on such record date or, if the Common Stock trades on an
         ex-dividend basis, on the date prior to the commencement of ex-dividend
         trading, less the value of such dividend or distribution (as determined
         in good faith by the Board of Directors of the Company) applicable to
         one share of Common Stock, and

                  (y) the denominator of which shall be such Current Market
         Price.

                  2.3. Treatment of Options and Convertible Securities. In case
the Company at any time or from time to time after the Initial Date shall issue,
sell, grant or assume, or shall fix a record date for the determination of
holders of any class of securities entitled to receive, any Options or
Convertible Securities, then, and in each such case, the maximum number of
Additional Shares of Common Stock (as set forth in the instrument relating
thereto, without regard to any provisions contained therein for a subsequent
adjustment of such number) issuable upon the exercise of such Options or, in the
case of Convertible Securities and Options therefor, the conversion or exchange
of such Convertible Securities, shall be deemed to be issued for purposes of
Section 2.2 as of the time of such issue, sale, grant or assumption or, in case
such a record date shall have been fixed, as of the close of business on such
record date (or, if the Common Stock trades on an ex-dividend basis, on the date
prior to the commencement of ex-dividend trading), provided that such Additional
Shares of Common Stock shall not be deemed to have been issued unless the
consideration per share (determined pursuant to Section 2.5) of such shares
would be less than the Base Price in effect, in each case, on the date of and
immediately prior to such issue, sale, grant or assumption or immediately prior
to the close of business on such record date (or, if

                                       4


the Common Stock trades on an ex-dividend basis, on the date prior to the
commencement of ex-dividend trading), as the case may be, and provided, further,
that in any such case in which Additional Shares of Common Stock are deemed to
be issued,

                  (a) no further adjustment of the Warrant Price shall be made
         upon the subsequent issue or sale of Additional Shares of Common Stock
         or Convertible Securities upon the exercise of such Options or the
         conversion or exchange of such Convertible Securities;

                  (b) if such Options or Convertible Securities by their terms
         provide, with the passage of time or otherwise, for any increase in the
         consideration payable to the Company, or decrease in the number of
         Additional Shares of Common Stock issuable, upon the exercise,
         conversion or exchange thereof (by change of rate or otherwise), the
         Warrant Price computed upon the original issue, sale, grant or
         assumption thereof (or upon the occurrence of the record date, or date
         prior to the commencement of ex-dividend trading, as the case may be,
         with respect thereto), and any subsequent adjustments based thereon,
         shall, upon any such increase or decrease becoming effective, be
         recomputed to reflect such increase or decrease insofar as it affects
         such Options, or the rights of conversion or exchange under such
         Convertible Securities, which are outstanding at such time;

                  (c) upon the expiration of any such Options or of the rights
         of conversion or exchange under any such Convertible Securities which
         shall not have been exercised (or upon purchase by the Company and
         cancellation or retirement of any such Options which shall not have
         been exercised or of any such Convertible Securities the rights of
         conversion or exchange under which shall not have been exercised), the
         Warrant Price computed upon the original issue, sale, grant or
         assumption thereof (or upon the occurrence of the record date, or date
         prior to the commencement of ex-dividend trading, as the case may be,
         with respect thereto), and any subsequent adjustments based thereon,
         shall, upon such expiration (or such cancellation or retirement, as the
         case may be), be recomputed as if:

                           (x) in the case of Options for Common Stock or of
                  Convertible Securities, the only Additional Shares of Common
                  Stock issued or sold were the Additional Shares of Common
                  Stock, if any, actually issued or sold upon the exercise of
                  such Options or the conversion or exchange of such Convertible
                  Securities and the consideration received therefor was (i) an
                  amount equal to (A) the consideration actually received by the
                  Company for the issue, sale, grant or assumption of all such
                  Options, whether or not exercised, plus (B) the

                                       5


                  consideration actually received by the Company upon such
                  exercise, minus (C) the consideration paid by the Company for
                  any purchase of such Options which were not exercised, or (ii)
                  an amount equal to (A) the consideration actually received by
                  the Company for the issue, sale, grant or assumption of all
                  such Convertible Securities which were actually converted or
                  exchanged, plus (B) the additional consideration, if any,
                  actually received by the Company upon such conversion or
                  exchange, minus (C) the consideration paid by the Company for
                  any purchase of such Convertible Securities the rights of
                  conversion or exchange under which were not exercised, and

                           (y) in the case of Options for Convertible
                  Securities, only the Convertible Securities, if any, actually
                  issued or sold upon the exercise of such Options were issued
                  at the time of the issue, sale, grant or assumption of such
                  Options, and the consideration received by the Company for the
                  Additional Shares of Common Stock deemed to have then been
                  issued was an amount equal to (i) the consideration actually
                  received by the Company for the issue, sale, grant or
                  assumption of all such Options, whether or not exercised, plus
                  (ii) the consideration deemed to have been received by the
                  Company (pursuant to Section 2.4) upon the issue or sale of
                  the Convertible Securities with respect to which such Options
                  were actually exercised, minus (iii) the consideration paid by
                  the Company for any purchase of such Options which were not
                  exercised;

                  (d) no readjustment pursuant to subdivision (b) or (c) above
         shall have the effect of increasing the Warrant Price by an amount in
         excess of the amount of the adjustment thereof originally made in
         respect of the issue, sale, grant or assumption of such Options or
         Convertible Securities, except as a result of any intervening events
         causing adjustments therein; and

                  (e) in the case of any such Options which expire by their
         terms not more than 30 days after the date of issue, sale, grant or
         assumption thereof, no adjustment of the Warrant Price shall be made
         until the expiration or exercise of all such Options, whereupon such
         adjustment shall be made in the manner provided in subdivision (c)
         above.

         In case at any time after the Initial Date the Company shall be
required to increase the number of Additional Shares of Common Stock subject to
any Option or into which any Convertible Securities (other than the Warrants)
are convertible or exchangeable pursuant to the operation of anti-dilution
provisions applicable thereto, such Additional Shares of Common Stock shall be
deemed to be issued for purposes of Section 2.2 as of the time of such increase.

                  2.4. Treatment of Stock Dividends, Stock Splits, Etc. In case
the Company at any time or from time to time after the Initial Date shall
declare or pay any dividend or other distribution on any class of stock of the
Company payable in Common Stock, or shall effect a subdivision of the
outstanding shares of Common Stock into a greater number of shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in Common

                                       6


Stock), then, and in each such case, Additional Shares of Common Stock shall be
deemed to have been issued (a) in the case of any such dividend, immediately
after the close of business on the record date for the determination of holders
of any class of securities entitled to receive such dividend, or (b) in the case
of any such subdivision, at the close of business on the day immediately prior
to the day upon which such corporate action becomes effective.

                  2.5. Computation of Consideration. For the purposes of this
Section 2:


                  (a) The consideration for the issue or sale of any Additional
         Shares of Common Stock or for the issue, sale, grant or assumption of
         any Options or Convertible Securities, irrespective of the accounting
         treatment of such consideration, shall

                           (x) insofar as it consists of cash, be computed at
                  the amount of cash received by the Company, without deducting
                  any expenses paid or incurred by the Company or any
                  commissions or compensation paid or concessions or discounts
                  allowed to underwriters, dealers or others performing similar
                  services and any accrued interest or dividends in connection
                  with such issue or sale,

                           (y) insofar as it consists of consideration
                  (including securities) other than cash, be computed at the
                  fair value thereof at the time of such issue or sale, as
                  determined in good faith by the Board of Directors of the
                  Company, without deducting any expenses paid or incurred by
                  the Company for any commissions or compensation paid or
                  concessions or discounts allowed to underwriters, dealers or
                  others performing similar services and any accrued interest or
                  dividends in connection with such issue or sale, and

                           (z) in case Additional Shares of Common Stock are
                  issued or sold or Convertible Securities are issued, sold,
                  granted or assumed together with other stock or securities or
                  other assets of the Company for a consideration which covers
                  both, be the proportion of such consideration so received,
                  computed as provided in subdivisions (x) and (y) above,
                  allocable to such Additional Shares of Common Stock or
                  Convertible Securities, as the case may be, all as determined
                  in good faith by the Board of Directors of the Company.

                  (b) All Options issued, sold, granted or assumed together with
         other stock or securities or other assets of the Company for a
         consideration which covers both and which does not set forth an
         allocation of such consideration in the documentation for such
         transaction, all Additional Shares of Common Stock, Options or
         Convertible Securities issued in payment of any dividend or other
         distribution on any class of stock of the Company and all Additional
         Shares of Common Stock issued to effect a subdivision of the
         outstanding shares of Common Stock into a greater number of shares of
         Common Stock (by reclassification or otherwise than by payment of a
         dividend in Common Stock) shall be deemed to have been issued without
         consideration.

                                       7


                  (c) Additional Shares of Common Stock deemed to have been
         issued for consideration pursuant to Section 2.3, relating to Options
         and Convertible Securities, shall be deemed to have been issued for a
         consideration per share determined by dividing

                           (x) the total amount, if any, received and receivable
                  by the Company as consideration for the issue, sale, grant or
                  assumption of the Options or Convertible Securities in
                  question, plus the minimum aggregate amount of additional
                  consideration (as set forth in the instruments relating
                  thereto, without regard to any provision contained therein for
                  a subsequent adjustment of such consideration) payable to the
                  Company upon the exercise in full of such Options or the
                  conversion or exchange of such Convertible Securities or, in
                  the case of Options for Convertible Securities, the exercise
                  of such Options for Convertible Securities and the conversion
                  or exchange of such Convertible Securities, in each case
                  computing such consideration as provided in the foregoing
                  subdivision (a), by

                           (y) the maximum number of shares of Common Stock (as
                  set forth in the instruments relating thereto, without regard
                  to any provision contained therein for a subsequent adjustment
                  of such number) issuable upon the exercise of such Options or
                  the conversion or exchange of such Convertible Securities.

                  (d) Additional Shares of Common Stock issued or deemed to have
         been issued pursuant to the operation of anti-dilution provisions
         applicable to Convertible Securities (other than the Warrants), Options
         or other securities of the Company (either as a result of the
         adjustments provided for by the Warrants or otherwise) shall be deemed
         to have been issued without consideration.

                  2.6. Adjustments for Combinations, Etc. In case the
outstanding shares of Common Stock shall be combined or consolidated, by
reclassification or otherwise, into a lesser number of shares of Common Stock,
the Warrant Price in effect immediately prior to such combination or
consolidation shall, concurrently with the effectiveness of such combination or
consolidation, be proportionately increased.

                  2.7. Dilution in Case of Other Securities. In case any Other
Securities shall be issued or sold or shall become subject to issue or sale upon
the conversion or exchange of any Common Stock (or Other Securities) of the
Company (or any issuer of Other Securities or any other Person referred to in
Section 3) or to subscription, purchase or other acquisition pursuant to any
options issued or granted by the Company (or any such other issuer or Person)
for a consideration such as to dilute, on a basis consistent with the standards
established in the other provisions of this Section 2, the purchase rights
granted by this Warrant, then, and in each such case, the computations,
adjustments and readjustments provided for in this Section 2 with respect to the
Warrant Price shall be made as nearly as possible in the manner so provided and
applied to determine the amount of Other Securities from time to time receivable
upon the exercise of this Warrant, so as to protect the holder of this Warrant
against the effect of such dilution.

                                       8


                  2.8. Minimum Adjustment of Warrant Price. If the amount of any
adjustment of the Warrant Price required pursuant to this Section 2 would be
less than one-tenth of one percent of the Warrant Price in effect at the time
such adjustment is otherwise so required to be made, such amount shall be
carried forward and adjustment with respect thereto made at the time of and
together with any subsequent adjustment which, together with such amount and any
other amount or amounts so carried forward, shall aggregate at least one-tenth
of one percent of such Warrant Price; provided that, upon the exercise of this
Warrant, all adjustments carried forward and not theretofore made up to and
including the date of such exercise shall be made to the nearest one
one-hundredth of a cent.

               3. Consolidation, Merger, Sale of Assets, Reorganization. Etc.


                  3.1. General Provisions. In case the Company, after the
Initial Date, (a) shall consolidate with or merge into any other Person and
shall not be the continuing or surviving corporation of such consolidation or
merger, or (b) shall permit any other Person to consolidate with or merge into
the Company and the Company shall be the continuing or surviving Person but, in
connection with such consolidation or merger, Common Stock or Other Securities
shall be changed into or exchanged for cash, stock or other securities of any
other Person or any other property, or (c) shall transfer all or substantially
all of its properties and assets to any other Person, or (d) shall effect a
capital reorganization or reclassification of Common Stock or Other Securities
(other than a capital reorganization or reclassification resulting in the issue
of Additional Shares of Common Stock for which adjustment in the Warrant Price
is provided in Section 2.2.1 or 2.2.2), then, and in the case of each such
transaction, the Company shall give written notice thereof to the holder of this
Warrant not less than 30 days prior to the consummation thereof and proper
provision shall be made so that, upon the basis and the terms and in the manner
provided in this Section 3, the holder of this Warrant, upon the exercise hereof
at any time after the consummation of such transaction, shall be entitled to
receive, at the aggregate Warrant Price in effect at the time of such
consummation for all Common Stock (or other Securities) issuable upon such
exercise immediately prior to such consummation, in lieu of the Common Stock (or
Other Securities) issuable upon such exercise prior to such consummation, the
highest amount of cash, securities or other property to which such holder would
actually have been entitled as a shareholder upon such consummation if such
holder had exercised this Warrant immediately prior thereto, subject to
adjustments (subsequent to such consummation) as nearly equivalent as possible
to the adjustments provided for in Section 2 and this Section 3, provided that
if a purchase, tender or exchange offer shall have been made to and accepted by
the holders of Common Stock under circumstances in which, upon completion of
such purchase, tender or exchange offer, the maker thereof, together with
members of any group (within the meaning of Section 13(d)(3) of the Exchange
Act) of which such maker is a part, and together with any affiliate or associate
of such maker (within the meaning of Rule 12b-2 under the Exchange Act) and any
members of any such group of which any such affiliate or associate is a part,
own beneficially (within the meaning of Rule 13d-3 under the Exchange Act) more
than 50% of the outstanding shares of Common Stock, and if the holder of this
Warrant so designates in such notice given to the Company, the holder of this
Warrant shall be entitled to receive the highest amount of cash, securities or
other property to which such holder would actually have been entitled as a
shareholder if the holder of this Warrant had exercised this Warrant prior to
the

                                       9


expiration of such purchase, tender or exchange offer, accepted such offer and
all of the Common Stock held by such holder had been purchased pursuant to such
purchase, tender or exchange offer, subject to adjustments (from and after the
consummation of such purchase, tender or exchange offer) as nearly equivalent as
possible to the adjustments provided for in Section 2 and this Section 3.

                  3.2. Assumption of Obligations. Notwithstanding anything
contained in this Warrant or the DTN Agreement to the contrary, the Company will
not effect any of the transactions described in subdivisions (a), (b) or (d) of
Section 3.1 unless, prior to the consummation thereof, each Person (other than
the Company) which may be required to deliver any cash, stock or other
securities or other property upon the exercise of this Warrant as provided
herein shall assume, by written instrument delivered to, and reasonably
satisfactory to, the holder of this Warrant, (a) the obligations of the Company
under this Warrant (and if the Company shall survive the consummation of such
transaction, such assumption shall be in addition to, and shall not release the
Company from, any continuing obligations of the Company under this Warrant) and
(b) the obligation to deliver to such holder such cash, stock or other
securities or other property as, in accordance with the foregoing provisions of
this Section 3, such holder may be entitled to receive, and such Person shall
have similarly delivered to such holder an opinion of counsel for such Person,
which counsel shall be reasonably satisfactory to such holder, stating that this
Warrant shall thereafter continue in full force and effect and the terms hereof
(including, without limitation, all of the provisions of Section 2 and this
Section 3) shall be applicable to the cash, stock or other securities or other
property which such Person may be required to deliver upon any exercise of this
Warrant or the exercise of any rights pursuant hereto.

               4. Other Dilutive Events. In case any event shall occur as to
which the provisions of Section 2 or Section 3 are not strictly applicable but
the failure to make any adjustment would not fairly protect the purchase rights
represented by this Warrant in accordance with the essential intent and
principles of such sections, then, in each such case, the Company shall appoint
a firm of independent public accountants of recognized national standing (which
may be the regular auditors of the Company), which shall give their opinion upon
the adjustment, if any, on a basis consistent with the essential intent and
principles established in Sections 2 and 3, necessary to preserve, without
dilution, the purchase rights represented by this Warrant. Upon receipt of such
opinion the Company will promptly mail a copy thereof to the holder of this
Warrant and shall make the adjustments described therein.

               5. No Dilution or Impairment. The Company will not, by amendment
of its certificate of incorporation or through any consolidation, merger,
reorganization, transfer of assets, dissolution, issue or sale of securities or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant, but will at all times in good faith assist
in the carrying out of all such terms and in the taking of all such action as
may be necessary or appropriate in order to protect the rights of the holder of
this Warrant against dilution or other impairment. Without limiting the
generality of the foregoing, the Company (a) will not permit the par value of
any shares of stock receivable upon the exercise of this Warrant to exceed the
amount payable therefor upon such exercise, (b) will take all such action as may
be necessary or appropriate in order that the Company may validly and legally
issue fully paid and


                                       10


nonassessable shares of stock upon the exercise of all outstanding warrants
issued by the Company (including this Warrant) from time to time, and (c) will
not take any action which results in any adjustment of the Warrant Price if the
total number of shares of Common Stock (or Other Securities) issuable after the
action upon the exercise of all outstanding warrants issued by the Company
(including this Warrant) would exceed the total number of shares of Common Stock
(or Other Securities) then authorized by the Company's certificate of
incorporation and available for the purpose of issue upon such exercise.

               6. Accountants' Report as to Adjustments. In each case of any
adjustment or readjustment in the shares of Common Stock (or Other Securities)
issuable upon the exercise of this Warrant, the Company at its expense will
promptly compute such adjustment or readjustment in accordance with the terms of
this Warrant, and will prepare a certificate of the chief financial officer of
the Company setting forth such adjustment or readjustment and showing in
reasonable detail the method of calculation thereof and the facts upon which
such adjustment or readjustment is based, including without limitation a
statement of (a) the consideration received or to be received by the Company for
any Additional Shares of Common Stock issued or sold or deemed to have been
issued, (b) the number of shares of Common Stock outstanding or deemed to be
outstanding, and (c) the Warrant Price in effect immediately prior to such issue
or sale and as adjusted and readjusted (if required by Section 2) on account
thereof. The Company will forthwith mail a copy of each such certificate to each
holder of a Warrant and will, upon the written request at any time of the holder
of this Warrant, furnish to such holder a like certificate setting forth the
Warrant Price at the time in effect and showing in reasonable detail how it was
calculated. In addition, with respect to any fiscal year of the Company during
which any such adjustment or readjustment shall have been made, the Company will
cause the independent public accountants reporting upon the Company's financial
statements for such fiscal year to verify, concurrently with their annual audit
of the Company's financial statements, the computations made by the Company
during such fiscal year and to prepare and to deliver to the holder of this
Warrant a report setting forth substantially the information described above in
this Section 6 with respect to all such adjustments and readjustments. The
Company will also keep copies of all such certificates and reports at its
principal office and will cause the same to be available for inspection at such
office during normal business hours by the holder of this Warrant or any
prospective purchaser of this Warrant designated by the holder thereof.

               7. Notices of Corporate Action. In the event of

                  (a) any taking by the Company of a record of the holders of
         any class of securities for the purpose of determining the holders
         thereof who are entitled to receive any dividend or other distribution,
         or any right to subscribe for, purchase or otherwise acquire any shares
         of stock of any class or any other securities or property, or to
         receive any other right, or

                  (b) any capital reorganization of the Company, any
         reclassification or recapitalization of the capital stock of the
         Company or any consolidation or merger involving the Company and any
         other Person or any transfer of all or substantially all the assets of
         the Company to any other Person, or

                                       11


                  (c) any voluntary or involuntary dissolution, liquidation or
         winding-up of the Company,

the Company will mail to the holder of this Warrant a notice specifying (x) the
date or expected date on which any such record is to be taken for the purpose of
such dividend, distribution or right, and the amount and character of such
dividend, distribution or right, and (y) the date or expected date on which any
such reorganization, reclassification, recapitalization, consolidation, merger,
transfer, dissolution, liquidation or winding-up is to take place and the time,
if any such time is to be fixed, as of which the holders of record of Common
Stock (or Other Securities) shall be entitled to exchange their shares of Common
Stock (or Other Securities) for the securities or other property deliverable
upon such reorganization, reclassification, recapitalization, consolidation,
merger, transfer, dissolution, liquidation or winding-up. Such notice shall be
mailed at least 20 days prior to the date therein specified, in the case of any
date referred to in the foregoing subdivision (x), and at least 30 days prior to
the date therein specified, in the case of the date referred to in the foregoing
subdivision (y).

               8. Restrictions on Transfer.

                  8.1. Restrictive Legends. Except as otherwise permitted by
this Section 8, each certificate for Common Stock (or Other Securities) issued
upon the exercise of this Warrant and each certificate issued upon the direct or
indirect Transfer of any such Common Stock (or Other Securities) shall be
stamped or otherwise imprinted with a legend in substantially the following
form:

         "The shares represented by this certificate have not been registered
         under the Securities Act of 1933 and may not be transferred except in
         compliance with such Act and applicable state securities laws. Such
         shares are also subject to certain restrictions on transferability
         imposed by a Common Stock Purchase Warrant expiring April 30, 2003, a
         copy of which is on file at the offices of the Company."

                  8.2. Notice of Proposed Transfer; Opinions of Counsel. Prior
to any Transfer of any Restricted Securities which are not registered under an
effective registration statement under the Securities Act (other than a Transfer
pursuant to Rule 144 or any comparable rule under such Act), the holder thereof
will give written notice to the Company of such holder's intention to effect
such Transfer and to comply in all other respects with this Section 8.2. Each
such notice (a) shall describe the manner and circumstances of the proposed
Transfer in sufficient detail to enable counsel to render the opinions referred
to below, and (b) shall designate counsel for the holder giving such notice (who
may be internal counsel for such holder). The holder giving such notice will
submit a copy thereof to the counsel designated in such notice and the Company
will promptly submit a copy thereof to its counsel. The following provisions
shall then apply:

                           (x) If in the opinion of such counsel for the holder
                  the proposed Transfer may be effected without registration (a
                  copy of which opinion shall be

                                       12


                  delivered to the Company), and if such opinion is reasonably
                  satisfactory to the Company, such holder shall thereupon be
                  entitled to Transfer such Restricted Securities in accordance
                  with the terms of the notice delivered by such holder to the
                  Company. Each Warrant or certificate, if any, issued upon or
                  in connection with such Transfer shall bear the appropriate
                  restrictive legend set forth in Section 8.1 unless, in the
                  opinion of such counsel and the Company's counsel, such legend
                  is no longer required to ensure compliance with the Securities
                  Act.

                           (y) If the opinion of such counsel for the holder is
                  not to the effect that the proposed Transfer may legally be
                  effected without registration of such Restricted Securities
                  under the Securities Act, such holder shall not be entitled to
                  Transfer such Restricted Securities (other than in a Transfer
                  pursuant to Rule 144 or any comparable rule under the
                  Securities Act) until the conditions specified in subdivision
                  (x) above shall be satisfied or until registration of such
                  Restricted Securities under the Securities Act has become
                  effective.

Notwithstanding the foregoing provisions of this Section 8.2, the holder of any
Restricted Securities shall be permitted to Transfer any such Restricted
Securities pursuant to Rule 144A under the Securities Act, provided that each
transferee agrees in writing to be bound by all the restrictions on transfer of
such Restricted Securities contained in this Section 8.2.

                  8.3. Termination of Restrictions. The restrictions imposed by
this Section 8 upon the transferability of Restricted Securities shall cease and
terminate as to any particular Restricted Securities (a) when such securities
shall have been effectively registered under the Securities Act and disposed of
in accordance with the registration statement covering such Restricted
Securities, (b) when, in the opinions of both counsel for the holder thereof and
counsel for the Company, such restrictions are no longer required in order to
ensure compliance with the Securities Act, or (c) when such securities may be
immediately sold by the holder as determined under Rule 144 under the Securities
Act. Whenever such restrictions shall terminate as to any Restricted Securities,
as soon as practicable thereafter and in any event within ten Business Days, the
holder thereof shall be entitled to receive from the Company, without expense
(other than transfer taxes, if any), new securities of like tenor not bearing
the legend set forth in Section 8.1 hereof.

               9. Registration under Securities Act, Etc.

                  9.1 Registration on Request.

         (a) Request. At any time and from time to time after September 30,
1999, upon the written request of DTN, requesting that the Company effect the
registration under the Securities Act of all or part of the Registrable
Securities and specifying the intended method of disposition thereof, the
Company will use its best efforts to effect its registration under the
Securities Act, including by means of a shelf registration pursuant to Rule 415
under the Securities Act if so requested in such request (but in the case of a
shelf registration only if the Company is then eligible to use Form S-2 or S-3
(or any successor forms)), of the Registrable Securities which the

                                       13


Company has been so requested to register by DTN for disposition in accordance
with the intended method of disposition stated in such request, all to the
extent requisite to permit the disposition (in accordance with the intended
methods thereof as aforesaid) of the Registrable Securities so to be registered;
provided that the Company shall not be required to effect the registration
pursuant to this Section 9.1 of any Warrants (but shall be required to effect
the registration of Registrable Securities described in clauses (b) and (c) of
the definition of Registrable Securities), and provided, further, that DTN, by
written notice to the Company within 10 Business Days after its receipt of a
copy of a notice from the managing underwriter delivered pursuant to Section
9.1(g), may withdraw such request and, on receipt of such notice of the
withdrawal of such request from DTN, the Company may elect not to effect such
registration. Subject to subdivision (g), the Company may include in such
registration other securities for sale for its own account or for the account of
any other Person.

         (b) Number of Registrations. The Company shall not be required to
effect more than one registration pursuant to this Section 9.1, provided that
such registration shall permit the disposition of at least 80% of the
Registrable Securities issuable to DTN upon exercise of all of the Warrants,
provided, further, that if one or more such registrations, in the aggregate,
shall not permit the disposition of at least 80% of such Registrable Securities,
the Company shall be required to effect one additional registration pursuant to
this Section 9.1 so that the aggregate number of such Registrable Securities
shall be at least 80%.

         (c) Registration Statement Form. The Company may, if permitted by law,
effect any registration requested under this Section 9.1 by the filing of a
registration statement on Form S-3 (or any successor or similar short form
registration statement) unless, if such registration involves an underwritten
Public Offering of such Registrable Securities, the managing underwriter of such
Public Offering shall notify the Company in writing that, in the judgment of
such managing underwriter, the use of a more detailed form specified in such
notice is of material importance to the success of the Public Offering of such
Registrable Securities, in which case such registration shall be effected on the
form so specified.

         (d) Expenses. The Company will pay all Registration Expenses in
connection with any registration and sale effected pursuant to this Section 9.1.

         (e) Selection of Underwriters. If, in the discretion of DTN, any
offering pursuant to this Section 9.1 shall constitute an underwritten offering,
the underwriter or underwriters thereof shall be selected, after consultation
with the Company, by DTN and shall be acceptable to the Company.

         (f) Effective Registration Statement. A registration requested pursuant
to this Section 9.1 will not be deemed to have been effected (x) unless it has
become effective, provided that a registration which does not become effective
after the Company has filed a registration statement with respect thereto solely
by reason of the refusal to proceed of DTN shall be deemed to have been effected
by the Company at the request of DTN, unless DTN shall have elected to pay all
Registration Expenses in connection with such registration, (y) if, after it has
become effective, such registration is interfered with by any stop order,
injunction or other order or requirement of

                                       14


the Commission or other governmental agency or court entered within one year of
the effectiveness of such registration if it is a shelf registration pursuant to
Rule 415 under the Securities Act or entered within 90 days of the effectiveness
of such registration if other than a shelf registration, or (z) if the
conditions to closing specified in the underwriting agreement entered into in
connection with such registration are not satisfied other than by reason of some
act or omission by DTN.

         (g) Priority in Requested Registrations. If a requested registration
pursuant to this Section 9.1 involves an underwritten offering, and the managing
underwriter shall advise the Company in writing (with a copy to DTN) that, in
its opinion, the total number of securities requested to be included in such
registration exceeds the number which can be sold in such offering, the Company
will include in any such registration to the extent of the number which the
Company is so advised can be sold in such offering (x) first, Registrable
Securities requested to be included in such registration by DTN, (y) second, any
securities proposed by the Company to be sold for its own account, and (z)
third, Other Securities of the Company proposed to be included in such
registration, in accordance with the priorities, if any, then existing among the
Company and the holders of such other securities.

         (h) Company Request for Delay. Except with respect to a registration
statement covering a shelf registration, the Company shall be entitled to
postpone for a reasonable period of time (but not exceeding 180 days) the filing
of any registration statement otherwise required to be prepared and filed by it
pursuant to this Section 9.1 if the Board of Directors of the Company
determines, in its reasonable judgment, that such registration and offering
would interfere with any financing, acquisition, corporate reorganization or
other material transaction involving the Company or any of its affiliates and
promptly gives DTN written notice of such determination, containing a general
statement of the reasons for such postponement and approximation of the
anticipated delay. If the Company shall so postpone the filing of a registration
statement, DTN shall have the right to withdraw the request for registration by
giving written notice to the Company within 30 days after receipt of the notice
of postponement and, in the event of such withdrawal, such request shall not be
counted for purposes of the requests for registration to which holders of
Registrable Securities are entitled pursuant to Section 9.1.

         (i) Shelf Registration Statement. The Company shall be deemed to have
complied with a request for registration made by DTN pursuant to this Section
9.1 if, at the time of such request, there shall be an effective shelf
registration statement on file with the Commission pursuant to Rule 415 under
the Securities Act covering the Registrable Securities which such holders shall
have requested to be registered, if such registration statement complies with
the provisions of this Section 9.1 and of Section 9.3 and if the Company
otherwise fulfills the requirements of Section 9.1 and 9.3 in respect of such
registration.

                  9.2 Incidental Registration.

         (a) Right to Include Registrable Securities. Notwithstanding any
limitation contained in Section 9.1, if the Company at any time on or prior to
April 30, 2005 proposes to register any of its securities under the Securities
Act (other than by a registration on Form S-4 or S-8 or any

                                       15


successor or similar forms), whether or not for sale for its own account, in a
manner which would permit registration of Registrable Securities for sale to the
public under the Securities Act, it will each such time give prompt written
notice to DTN of its intention to do so and of DTN's rights under this Section
9.2. Upon the written request of DTN made within 20 days after receipt of any
such notice (which request shall specify the Registrable Securities intended to
be disposed of by DTN and the intended method of disposition thereof), the
Company will use its best efforts to effect the registration under the
Securities Act of all Registrable Securities which the Company has been so
requested to register by DTN, to the extent requisite to permit the disposition
(in accordance with the intended methods thereof as aforesaid) of the
Registrable Securities so to be registered, by inclusion of such Registrable
Securities in the registration statement which covers the securities which the
Company proposes to register, provided that (x) the Company shall not be
required to effect the registration pursuant to this Section 9.2 of any Warrants
(but shall be required to effect the registration of Registrable Securities
described in clauses (b) and (c) of the definition of Registrable Securities)
and (y) if, at any time after giving written notice of its intention to register
any securities and prior to the effective date of the registration statement
filed in connection with such registration, the Company shall determine for any
reason not to register or to delay registration of such securities, the Company
may, at its election, give written notice of such determination to DTN and,
thereupon, (i) in the case of a determination not to register, shall be relieved
of its obligation to register any Registrable Securities in connection with such
registration (but not from its obligation to pay the Registration Expenses in
connection therewith), without prejudice, however, to the rights of DTN to
request that such registration be effected as a registration under Section 9.1,
and (ii) in the case of a determination to delay registering, shall be permitted
to delay registering any Registrable Securities for the same period as the delay
in registering such other securities. No registration effected under this
Section 9.2 shall relieve the Company of its obligation to effect any
registration statement upon request under Section 9.1. The Company will pay all
Registration Expenses in connection with each registration of Registrable
Securities requested pursuant to this Section 9.2.

         (b) Priority in Incidental Registrations. If a registration pursuant to
this Section 9.2 involves an underwritten offering and the managing underwriter
advises the Company in writing that, in its opinion, the number of securities
requested to be included in such registration exceeds the number which can be
sold in such offering, the Company will include in such registration to the
extent of the number which the Company is so advised can be sold in such
offering securities determined as follows:

                  (x) if such registration as initially proposed by the Company
         was solely a primary registration of its securities, (i) first, the
         securities proposed by the Company to be sold for its own account, (ii)
         second, any Registrable Securities requested to be included in such
         registration, and (iii) third, any other securities of the Company
         proposed to be included in such registration, in accordance with the
         priorities, if any, then existing among the Company and the holders of
         such other securities, and

                  (y) if such registration as initially proposed by the Company
          was in whole or in part requested by holders of securities of the
          Company, other than DTN, pursuant to demand registration rights, (i)
          first, securities proposed by the Company to be sold for its

                                       16


         own account, (ii) second, such securities held by the holders
         initiating such registration, in accordance with the priorities, if
         any, then existing among the Company and the holders of such
         securities, (iii) third, any Registrable Securities requested to be
         included in such registration, and (iv) fourth, any other securities of
         the Company proposed to be included in such registration, in accordance
         with the priorities, if any, then existing among the Company and the
         holders of such other securities.

                  9.3. Registration Procedures. If and whenever the Company is
required to use its best efforts to effect the registration of any Registrable
Securities under the Securities Act as provided in Sections 9.1 and 9.2, the
Company will as expeditiously as possible:

                  (a) prepare and file with the Commission the requisite
         registration statement (including such audited financial statements as
         may be required by the Securities Act or the rules and regulations
         promulgated thereunder) to effect such registration and use its best
         efforts to cause such registration statement to become effective,
         provided that before filing such registration statement or any
         amendments thereto, the Company will furnish to the counsel selected by
         DTN copies of all such documents proposed to be filed, which documents
         will be subject to the review of such counsel;

                  (b) prepare and file with the Commission such amendments and
         supplements to such registration statement and the prospectus used in
         connection therewith as may be necessary to maintain the effectiveness
         of such registration statement and to comply with the provisions of the
         Securities Act with respect to the disposition of all securities
         covered by such registration statement until the earlier of such time
         as all of such securities have been disposed of in accordance with the
         intended methods of disposition by the seller or sellers thereof set
         forth in such registration statement and the expiration of 90 days
         after such registration statement becomes effective, except with
         respect to any such registration statement filed pursuant to Rule 415
         (or any successor Rule) under the Securities Act, in which case such
         period shall be one year;

                  (c) furnish to DTN such number of conformed copies of such
         registration statement and of each such amendment and supplement
         thereto (in each case including all exhibits), such number of copies of
         the prospectus contained in such registration statement (including each
         preliminary prospectus and any summary prospectus) and any other
         prospectus filed under Rule 424 under the Securities Act, in conformity
         with the requirements of the Securities Act, and such other documents,
         as DTN may reasonably request;

                  (d) use its best efforts to register or qualify all
         Registrable Securities and other securities covered by such
         registration statement under such other securities or blue sky laws of
         such jurisdictions as DTN shall reasonably request, to keep such
         registration or qualification in effect for so long as such
         registration statement remains in effect, and take any other action
         which may be reasonably necessary or advisable to enable DTN to
         consummate the disposition in such jurisdictions of the securities
         owned by DTN, except that the Company shall not for any such purpose be
         required to qualify generally to do

                                       17


         business as a foreign corporation in any jurisdiction wherein it would
         not but for the requirements of this subdivision (d) be obligated to be
         so qualified or to consent to general service of process in any such
         jurisdiction;

                     (e) if such registration includes an underwritten Public
         Offering, furnish to DTN a signed counterpart, addressed to DTN (and
         the underwriters), of

                            (x) an opinion of counsel for the Company, dated the
                  date of any closing under the underwriting agreement,
                  reasonably satisfactory in form and substance to DTN, and

                           (y) a "comfort" letter, dated the effective date of
                  such registration statement and the date of any closing under
                  the underwriting agreement, signed by the independent public
                  accountants who have certified the Company's financial
                  statements included in such registration statement,

         covering substantially the same matters with respect to such
         registration statement (and the prospectus included therein) and, in
         the case of the accountants' letter, with respect to events subsequent
         to the date of such financial statements, as are customarily covered in
         opinions of issuer's counsel and in accountants' letters delivered to
         the underwriters in underwritten Public Offerings of securities and, in
         the case of the accountants' letter, such other financial matters, as
         the underwriters may reasonably request;

                  (f) immediately notify DTN (w) when the prospectus or any
         prospectus supplement or post-effective amendment has been filed, and,
         with respect to the registration statement or any post-effective
         amendment, when the same has become effective, (x) of any request by
         the Commission for amendments or supplements to the registration
         statement or the prospectus or for additional information, (y) of the
         issuance by the Commission of any stop order suspending the
         effectiveness of the registration statement or the initiation of any
         proceedings for that purpose and (z) of the receipt by the Company of
         any notification with respect to the suspension of the qualification of
         the Registrable Securities for sale in any jurisdiction or the
         initiation or threatening of any proceeding for such purpose;

                  (g) use its reasonable best efforts to obtain the withdrawal
         of any order suspending the effectiveness of the registration statement
         at the earliest possible time;

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

                                       18


         purchasers of such securities, such prospectus shall not include an
         untrue statement of a material fact or omit to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading in the light of the circumstances under which
         they were made; and

                  (i) otherwise use its best efforts to comply with all
         applicable rules and regulations of the Commission, and make available
         to its security holders, as soon as reasonably practicable, an earnings
         statement covering the period of at least twelve months, but not more
         than eighteen months, beginning with the first full calendar month
         after the effective date of such registration statement, which earnings
         statement shall satisfy the provisions of Section 11(a) of the
         Securities Act, and not file any amendment or supplement to such
         registration statement or prospectus to which DTN shall have reasonably
         objected on the grounds that such amendment or supplement does not
         comply in all material respects with the requirements of the Securities
         Act or of the rules or regulations thereunder, having been furnished
         with a copy thereof at least three business days prior to the filing
         thereof.

The Company may require DTN to furnish the Company such information regarding
DTN and the distribution of such securities as the Company may from time to time
reasonably request in writing.

                  9.4 Underwritten Offerings.

         (a) Requested Underwritten Offerings. If requested by the underwriters
for any underwritten offering by holders of Registrable Securities pursuant to
the registration requested under Section 9.1, the Company will enter into an
underwriting agreement with such underwriters for such offering, such agreement
to be satisfactory in substance and form to DTN and the underwriters and to
contain such representations and warranties by the Company and such other terms
as are customarily contained in agreements of this type, including, without
limitation, indemnities to the effect and to the extent provided in Section 9.6.
DTN shall be a party to such underwriting agreement. DTN shall be required to
make such representations and warranties to and agreements with the Company or
the underwriters as are customarily contained in such agreements.

         (b) Incidental Underwritten Offerings. If the Company at any time
proposes to register any of its securities under the Securities Act as
contemplated by Section 9.2 and such securities are to be distributed by or
through one or more underwriters, the Company will, subject to the provisions of
Section 9.2(b), if requested by DTN, request such underwriters to include the
Registrable Securities to be offered and sold by DTN among the securities to be
distributed by such underwriters. DTN shall be a party to the underwriting
agreement between the Company and such underwriters. DTN shall be required to
make such representations and warranties and agreements with the Company or the
underwriters as are customarily contained in such agreements.

                                       19


         (c) Holdback Agreements. (x) DTN agrees, if so required by the managing
underwriter, not to effect any public sale or distribution of securities of the
Company of the same class as the securities included in such registration
statement, during the seven days prior to the date on which any underwritten
registration pursuant to Section 9.1 or 9.2 has become effective and the 90 days
thereafter, or such longer period as may be required by the managing
underwriter.

                  (y) The Company agrees not to effect any public sale or
distribution of its equity securities or securities convertible into or
exchangeable or exercisable for any of such securities during the seven days
prior to the date on which any underwritten registration pursuant to Section 9.1
or 9.2 has become effective and the 90 days thereafter (or such longer period as
may be required by the underwriter), except as part of such underwritten
registration and except pursuant to registrations on Form S-4 or S-8 or any
successor or similar forms thereto.

                  9.5 Preparation; Reasonable Investigation. In connection with
the preparation and filing of each registration statement under the Securities
Act, the Company will give DTN, the underwriter, if any, and counsel for the
underwriter, the opportunity to participate in the preparation of such
registration statement, each prospectus included therein or filed with the
Commission, and each amendment thereof or supplement thereto, and will give each
of them such access to its books and records and such opportunities to discuss
the business of the Company with its officers and the independent public
accountants who have certified its financial statements as shall be necessary,
in the opinion of DTN and such underwriter, to conduct a reasonable
investigation within the meaning of the Securities Act.

                  9.6 Indemnification. (a) The Company will, and hereby does,
indemnify, to the extent permitted by applicable law, DTN, its officers and
directors, and each Person, if any, who controls DTN within the meaning of
Section 15 of the Securities Act, against all losses, claims, damages,
liabilities (or proceedings in respect thereof) and expenses (under the
Securities Act or common law or otherwise), joint or several, caused by any
untrue statement or alleged untrue statement of a material fact contained in any
registration statement or prospectus (and as amended or supplemented if the
Company shall have furnished any amendments or supplements thereto) or any
preliminary prospectus or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages, liabilities (or proceedings in respect thereof) or expenses are caused
by any untrue statement or alleged untrue statement contained in or by any
omission or alleged omission from information furnished in writing to the
Company by DTN expressly for use therein. If the offering pursuant to any
registration statement provided for under this Agreement is made through
underwriters, no action or failure to act on the part of such underwriters shall
affect the obligations of the Company to indemnify DTN or any other Person
pursuant to the preceding sentence. If the offering pursuant to any registration
statement provided for under this Agreement is made through underwriters, the
Company agrees to enter into an underwriting agreement in customary form with
such underwriters and the Company agrees to indemnify such underwriters, their
officers and directors, if any, and each Person, if any, who controls such
underwriters within the meaning of Section 15 of the Securities Act to the same
extent as hereinbefore provided with respect to the

                                       20


indemnification of DTN; provided that the Company shall not be required to
indemnify DTN or any such underwriter, or any officer or director of DTN or such
underwriter or any Person who controls DTN or such underwriter within the
meaning of Section 15 of the Securities Act, to the extent that the loss, claim,
damage, liability (or proceedings in respect thereof) or expense for which
indemnification is claimed results from DTN's or such underwriter's failure to
send or give a copy of the amended or supplemented final prospectus to the
Person asserting an untrue statement or alleged untrue statement or omission or
alleged omission at or prior to the written confirmation of the sale of
Registrable Securities to such Person if such statement or omission was
corrected in such amended or supplemented final prospectus prior to such written
confirmation and DTN or the underwriter, as the case may be, was given notice of
the availability of such amended or supplemented final prospectus.

         (b) DTN will indemnify, to the extent permitted by applicable law, the
Company, its officers and directors and each Person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act, against any
losses, claims, damages, liabilities (or proceedings in respect thereof) and
expenses resulting from any untrue statement or alleged untrue statement of a
material fact or any omission or alleged omission of a material fact required to
be stated in the registration statement or prospectus or preliminary prospectus
or any amendment thereof or supplement thereto or necessary to make the
statements therein not misleading, but only to the extent that such untrue
statement is contained in or such omission is from information so furnished in
writing by DTN expressly for use therein, provided that DTN's obligations
hereunder shall be limited to an amount equal to the proceeds to DTN of the
Registrable Securities sold pursuant to such registration statement.

         (c) Any Person entitled to indemnification under the provisions of this
Section 9.6 shall (x) give prompt notice to the indemnifying party of any claim
with respect to which it seeks indemnification (but the failure of any
indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under the preceding subdivisions of this
Section 9.6, except to the extent that the indemnifying party is actually
prejudiced by such failure) and (y) unless a conflict of interest between such
indemnified and indemnifying parties exists in respect of such claim, permit
such indemnifying party to assume the defense of such claim, with counsel
reasonably satisfactory to the indemnified party; and if such defense is so
assumed, such indemnifying party shall not enter into any settlement without the
consent of the indemnified party if such settlement attributes liability to the
indemnified party and such indemnifying party shall not be subject to any
liability for any settlement made without its consent (which shall not be
unreasonably withheld); and any underwriting agreement entered into with respect
to any registration statement provided for under this Agreement shall so
provide. In the event an indemnifying party shall not be entitled, or elects
not, to assume the defense of a claim, such indemnifying party shall not be
obligated to pay the fees and expenses of more than one counsel or firm of
counsel for all parties indemnified by such indemnifying party in respect of
such claim, unless a conflict of interest exists between such indemnified party
and any other of such indemnified parties in respect to such claim. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of an indemnified

                                       21


party, its officers, directors or any Person, if any, who controls such party as
aforesaid, and shall survive the transfer of such securities by such holder.

         (d) If the indemnification provided for in this Section 9.6 shall for
any reason be held by a court to be unavailable to an indemnified party under
Section 9.6(a) or (b) hereof in respect of any loss, claim, damage or liability,
or any action in respect thereof, then, in lieu of the amount paid or payable
under Section 9.6(a) or (b), the indemnified party and the indemnifying party
under Section 9.6(a) or (b) shall contribute to the aggregate losses, claims,
damages and liabilities (including legal or other expenses reasonably incurred
in connection with investigating the same), (x) in such proportion as is
appropriate to reflect the relative fault of the Company, DTN and the
underwriters, if any, which resulted in such loss, claim, damage or liability,
or action or proceeding in respect thereof, with respect to the statements or
omissions which resulted in such loss, claim, damage or liability, or action or
proceeding in respect thereof, as well as any other relevant equitable
considerations or (y) if the allocation provided by clause (x) above is not
permitted by applicable law, in such proportion as shall be appropriate to
reflect the relative benefits received by the Company, DTN and the underwriters,
if any, from the offering of the securities covered by such registration
statement, provided, that for purposes of clauses (x) or (y), the relative
benefits received by DTN shall be deemed not to exceed the amount of proceeds
received by DTN and DTN shall not be required to contribute any amount in excess
of the amount it could have been required to pay to an indemnified party if the
indemnity under subsection (a) of this Section 9.6 was available. No Person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any Person who was
not guilty of such fraudulent misrepresentation. In addition, no Person shall be
obligated to contribute hereunder any amounts in payment for any settlement of
any action or claim effected without such Person's consent, which consent shall
not be unreasonably withheld.

                  9.7 Registration Rights to Others. If the Company shall at any
time after the date of this Warrant provide to any holder of any securities of
the Company rights with respect to the registration of such securities under the
Securities Act, such rights shall not be in conflict with any of the rights
provided in this Section 9 to the holders of Registrable Securities; provided,
however, the foregoing shall not preclude the Company from granting registration
rights which are more favorable than those contained in this Warrant so long as
such rights do not preclude the Company from complying with the terms of this
Warrant.

                  9.8 Rule 144. If and when the Common Stock is either listed,
designated or authorized as provided in Section 9.3(j), the Company shall take
all actions reasonably necessary to enable DTN to sell such shares of Common
Stock issuable upon exercise of this Warrant without registration under the
Securities Act within the limitation of the provisions of Rule 144 under the
Securities Act, as such Rule may be amended from time to time, or any similar
rules or regulations hereafter adopted by the Commission, including, without
limitation, filing on a timely basis all reports required to be filed pursuant
to the Exchange Act. Notwithstanding the provisions of Sections 9.1 and 9.2, the
Company has no obligation to effect the registration of any Registrable
Securities as provided in such sections if DTN can then sell under Rule 144 all
the Registrable Securities which otherwise would be registered in accordance
with such sections,

                                       22


as applicable; provided such exception does not preclude DTN from exercising its
registration rights on a future occasion.

               10. Availability of Information. The Company will cooperate with
each holder of any Restricted Securities in supplying such information as may be
necessary for such holder to complete and file any information reporting forms
presently or hereafter required by the Commission as a condition to the
availability of an exemption from the Securities Act for the sale of any
Restricted Securities. The Company will furnish to the holder of this Warrant,
promptly upon their becoming available, copies of all financial statements,
reports, notices and proxy statements sent or made available generally by the
Company to its stockholders, and copies of all regular and periodic reports and
all registration statements and prospectuses filed by the Company with any
securities exchange or with the Commission.

               11. Reservation of Stock, Etc. The Company will at all times
reserve and keep available, solely for issuance and delivery upon exercise of
this Warrant, the number of shares of Common Stock (or Other Securities) from
time to time issuable upon exercise of this Warrant at the time outstanding. All
shares of Common Stock (or Other Securities) shall be duly authorized and, when
issued upon such exercise, shall be validly issued and, in the case of shares,
fully paid and nonassessable, with no liability on the part of the holders
thereof.

               12. Listing on Securities Exchange. The Company will, at all
times after any Common Stock is so listed, designated or authorized as indicated
below, (a) list on each national securities exchange on which any Common Stock
may at any time be listed, subject to official notice of issuance upon exercise
of this Warrant, and will maintain such listing of, all shares of Common Stock
from time to time issuable upon exercise of this Warrant or (b) secure and
maintain designation of all shares of Common Stock from time to time issuable
upon exercise of this Warrant as a NASDAQ "national market system security"
within the meaning of Rule llAa2-1 of the Commission or, failing that, secure
NASDAQ authorization for such shares of Common Stock.

               13. Ownership, Transfer and Substitution of Warrants.

                  13.1. Ownership of Warrants. The Company may treat the person
in whose name this Warrant is registered on the register kept at the principal
office of the Company as the owner and holder thereof for all purposes,
notwithstanding any notice to the contrary, except that, if and when any Warrant
is properly assigned in blank, the Company may (but shall not be obligated to)
treat the bearer thereof as the owner of such Warrant for all purposes,
notwithstanding any notice to the contrary. Subject to Section 8, a Warrant, if
properly assigned, may be exercised by a new holder without first having a new
Warrant issued.

                  13.2. Transfer and Exchange of Warrants. Upon the surrender of
any Warrant, properly endorsed, for registration of transfer or for exchange at
the principal office of the Company, the Company at its expense will (subject to
compliance with Section 8, if applicable) execute and deliver to or upon the
order of the holder thereof a new Warrant or Warrants of like tenor, in
denominations of at least 1,000 shares, in the name of such holder or as such
holder

                                       23


(upon payment by such holder of any applicable transfer taxes) may direct,
calling in the aggregate on the face or faces thereof for the number of shares
of Common Stock called for on the face or faces of the Warrant or Warrants so
surrendered.

                  13.3. Replacement of Warrants. Upon receipt of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of any Warrant and, in the case of any such loss, theft or
destruction of any Warrant held by a Person other than the Purchaser or any
institutional investor, upon delivery of indemnity reasonably satisfactory to
the Company in form and amount or, in the case of any such mutilation, upon
surrender of such Warrant for cancellation at the principal office of the
Company, the Company at its expense will execute and deliver, in lieu thereof, a
new Warrant of like tenor.
