               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.  Incorporation of Documents by Reference

         Jupiter Communications, Inc. (the "Registrant") hereby incorporates by
reference into this Registration Statement the following documents previously
filed with the Securities and Exchange Commission (the "SEC"):

         (a)      The Registrant's Annual Report on Form 10-K for the fiscal
                  year ended December 31, 1999, filed with the SEC on March 30,
                  2000 pursuant to Section 13 of the Securities Exchange Act of
                  1934, as amended (the "1934 Act");

         (b)      The Registrant's Quarterly report on Form 10-Q for the fiscal
                  quarter ended March 31, 2000, filed with the SEC on May 15,
                  2000;

         (c)      The Registrant's Current Reports on Form 8-K, filed with the
                  SEC on March 30, 2000 and April 25, 2000 (as amended on May
                  15, 2000); and

         (d)      The Registrant's Registration Statement No. 000-27537 on Form
                  8-A12G filed with the SEC on October 4, 1999 in which there
                  is described the terms, rights and provisions applicable to
                  the Registrant's outstanding Common Stock.

         All reports and definitive proxy or information statements filed
pursuant to Section 13(a), 13(c), 14 or 15(d) of the 1934 Act after the date of
this Registration Statement and prior to the filing of a post-effective
amendment which indicates that all securities offered hereby have been sold or
which deregisters all securities then remaining unsold shall be deemed to be
incorporated by reference into this Registration Statement and to be a part
hereof from the date of filing of such documents. Any statement contained in a
document incorporated or deemed to be incorporated by reference herein shall be
deemed to be modified or superseded for purposes of this Registration Statement
to the extent that a statement contained herein or in any subsequently filed
document which also is deemed to be incorporated by reference herein modifies
or supersedes such statement. Any such statement so modified or superseded
shall not be deemed, except as so modified or superseded, to constitute a part
of this Registration Statement.

Item 4.  Description of Securities

         Not Applicable.

Item 5.  Interests of Named Experts and Counsel

         Not Applicable.

Item 6.  Indemnification of Directors and Officers

         The Registrant's certificate of incorporation, as amended and
restated, in effect as of the date hereof, provides that, except to the extent
prohibited by the Delaware General Corporation Law, as amended (the "DGCL"),
the Registrant's directors shall not be personally liable to the Registrant or
its stockholders for monetary damages for any breach of fiduciary duty as
directors of the Registrant. Under the DGCL, the directors have a fiduciary
duty to the Registrant which is not eliminated by this provision of the
Certificate and, in appropriate circumstances, equitable remedies such as
injunctive or other forms of non-monetary relief will remain available. In
addition, each director will continue to be subject to liability under the DGCL
for breach of the director's duty of loyalty to the Registrant, for acts or
omissions which are found by a court of competent jurisdiction to be not in
good faith or involving intentional misconduct, for knowing violations of law,
for actions leading to improper personal benefit to the director, and for
payment of dividends or approval of stock repurchases or redemptions that are
prohibited by DGCL. This provision also does not affect the directors'
responsibilities under any other laws, such as the Federal securities laws or
state or Federal environmental laws.



                                      II-1


<PAGE>   3

         Section 145 of the DGCL empowers a corporation to indemnify its
directors and officers and to purchase insurance with respect to liability
arising out of their capacity or status as directors and officers, provided
that this provision shall not eliminate or limit the liability of a director:
(i) for any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) arising under
Section 174 of the DGCL, or (iv) for any transaction from which the director
derived an improper personal benefit. The DGCL provides further that the
indemnification permitted thereunder shall not be deemed exclusive of any other
rights to which the directors and officers may be entitled under the
corporation's bylaws, any agreement, a vote of stockholders or otherwise. The
Certificate eliminates the personal liability of directors to the fullest
extent permitted by Section 102(b)(7) of the DGCL and provides that the
Registrant shall fully indemnify any person who was or is made or is threatened
to be made a party or is otherwise involved in any action, suit or proceeding
(whether civil, criminal, administrative or investigative) by reason of the
fact that such person is or was or has agreed to become, or a person for whom
such person is the legal representative, is or was or has agreed to become a
director or officer of the Registrant or, while a director or officer of the
Registrant, is or was serving at the request of the Registrant as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust, enterprise or nonprofit entity, including service with respect to
employee benefit plans, against all liability and loss suffered and expenses
(including attorney's fees), reasonably incurred by such person in connection
with such action, suit or proceeding.

         At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the Certificate. The Registrant is not aware of any
threatened litigation or proceeding that may result in a claim for such
indemnification.

Item 9.  Undertakings.

         A.       The undersigned Registrant hereby undertakes:  (1) to file,
during any period in which offers or sales are being made, a post-effective
amendment to this Registration Statement (i) to include any prospectus required
by Section 10(a)(3) of the 1933 Act, (ii) to reflect in the prospectus any
facts or events arising after the effective date of this Registration Statement
(or the most recent post-effective amendment thereof) which, individually or in
the aggregate, represent a fundamental change in the information set forth in
this Registration Statement and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information in this
Registration Statement; provided, however, that clauses (1)(i) and (1)(ii)
shall not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed by the
Registrant pursuant to Section 13 or Section 15(d) of the 1934 Act that are
incorporated by reference into this Registration Statement; (2) that for the
purpose of determining any liability under the 1933 Act each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof; and
(3) to remove from registration by means of a




                                      II-2


<PAGE>   4

post-effective amendment any of the securities being registered which remain
unsold at the termination of the Internet Research Group (formerly,
Collaborative Marketing, Inc.) 1999 Stock Option Plan.

         B.       The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the 1933 Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
1934 Act that is incorporated by reference into this Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

         C.       Insofar as indemnification for liabilities arising under the
1933 Act may be permitted to directors, officers, or controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that, in the opinion of the SEC, such indemnification is
against public policy as expressed in the 1933 Act, and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer, or controlling person of the Registrant in the
successful defense of any action, suit, or proceeding) is asserted by such
director, officer, or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the 1933 Act and will be governed by the
final adjudication of such issue.

Item 3.  Incorporation of Documents by Reference

         Jupiter Communications, Inc. (the "Registrant") hereby incorporates by
reference into this Registration Statement the following documents previously
filed with the Securities and Exchange Commission (the "SEC"):

         (a)      The Registrant's Annual Report on Form 10-K for the fiscal
                  year ended December 31, 1999, filed with the SEC on March 30,
                  2000 pursuant to Section 13 of the Securities Exchange Act of
                  1934, as amended (the "1934 Act");

         (b)      The Registrant's Quarterly report on Form 10-Q for the fiscal
                  quarter ended March 31, 2000, filed with the SEC on May 15,
                  2000;

         (c)      The Registrant's Current Reports on Form 8-K, filed with the
                  SEC on March 30, 2000 and April 25, 2000 (as amended on May
                  15, 2000); and

         (d)      The Registrant's Registration Statement No. 000-27537 on Form
                  8-A12G filed with the SEC on October 4, 1999 in which there
                  is described the terms, rights and provisions applicable to
                  the Registrant's outstanding Common Stock.

         All reports and definitive proxy or information statements filed
pursuant to Section 13(a), 13(c), 14 or 15(d) of the 1934 Act after the date of
this Registration Statement and prior to the filing of a post-effective
amendment which indicates that all securities offered hereby have been sold or
which deregisters all securities then remaining unsold shall be deemed to be
incorporated by reference into this Registration Statement and to be a part
hereof from the date of filing of such documents. Any statement contained in a
document incorporated or deemed to be incorporated by reference herein shall be
deemed to be modified or superseded for purposes of this Registration Statement
to the extent that a statement contained herein or in any subsequently filed
document which also is deemed to be incorporated by reference herein modifies
or supersedes such statement. Any such statement so modified or superseded
shall not be deemed, except as so modified or superseded, to constitute a part
of this Registration Statement.

Item 4.  Description of Securities

         Not Applicable.

Item 5.  Interests of Named Experts and Counsel

         Not Applicable.

Item 6.  Indemnification of Directors and Officers

         The Registrant's certificate of incorporation, as amended and
restated, in effect as of the date hereof, provides that, except to the extent
prohibited by the Delaware General Corporation Law, as amended (the "DGCL"),
the Registrant's directors shall not be personally liable to the Registrant or
its stockholders for monetary damages for any breach of fiduciary duty as
directors of the Registrant. Under the DGCL, the directors have a fiduciary
duty to the Registrant which is not eliminated by this provision of the
Certificate and, in appropriate circumstances, equitable remedies such as
injunctive or other forms of non-monetary relief will remain available. In
addition, each director will continue to be subject to liability under the DGCL
for breach of the director's duty of loyalty to the Registrant, for acts or
omissions which are found by a court of competent jurisdiction to be not in
good faith or involving intentional misconduct, for knowing violations of law,
for actions leading to improper personal benefit to the director, and for
payment of dividends or approval of stock repurchases or redemptions that are
prohibited by DGCL. This provision also does not affect the directors'
responsibilities under any other laws, such as the Federal securities laws or
state or Federal environmental laws.

                                      II-1

         Section 145 of the DGCL empowers a corporation to indemnify its
directors and officers and to purchase insurance with respect to liability
arising out of their capacity or status as directors and officers, provided
that this provision shall not eliminate or limit the liability of a director:
(i) for any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) arising under
Section 174 of the DGCL, or (iv) for any transaction from which the director
derived an improper personal benefit. The DGCL provides further that the
indemnification permitted thereunder shall not be deemed exclusive of any other
rights to which the directors and officers may be entitled under the
corporation's bylaws, any agreement, a vote of stockholders or otherwise. The
Certificate eliminates the personal liability of directors to the fullest
extent permitted by Section 102(b)(7) of the DGCL and provides that the
Registrant shall fully indemnify any person who was or is made or is threatened
to be made a party or is otherwise involved in any action, suit or proceeding
(whether civil, criminal, administrative or investigative) by reason of the
fact that such person is or was or has agreed to become, or a person for whom
such person is the legal representative, is or was or has agreed to become a
director or officer of the Registrant or, while a director or officer of the
Registrant, is or was serving at the request of the Registrant as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust, enterprise or nonprofit entity, including service with respect to
employee benefit plans, against all liability and loss suffered and expenses
(including attorney's fees), reasonably incurred by such person in connection
with such action, suit or proceeding.

         At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the Certificate. The Registrant is not aware of any
threatened litigation or proceeding that may result in a claim for such
indemnification.

Item 9.  Undertakings.

         A.       The undersigned Registrant hereby undertakes:  (1) to file,
during any period in which offers or sales are being made, a post-effective
amendment to this Registration Statement (i) to include any prospectus required
by Section 10(a)(3) of the 1933 Act, (ii) to reflect in the prospectus any
facts or events arising after the effective date of this Registration Statement
(or the most recent post-effective amendment thereof) which, individually or in
the aggregate, represent a fundamental change in the information set forth in
this Registration Statement and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information in this
Registration Statement; provided, however, that clauses (1)(i) and (1)(ii)
shall not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed by the
Registrant pursuant to Section 13 or Section 15(d) of the 1934 Act that are
incorporated by reference into this Registration Statement; (2) that for the
purpose of determining any liability under the 1933 Act each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof; and
(3) to remove from registration by means of a

                                      II-2

post-effective amendment any of the securities being registered which remain
unsold at the termination of the Internet Research Group (formerly,
Collaborative Marketing, Inc.) 1999 Stock Option Plan.

         B.       The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the 1933 Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
1934 Act that is incorporated by reference into this Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

         C.       Insofar as indemnification for liabilities arising under the
1933 Act may be permitted to directors, officers, or controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that, in the opinion of the SEC, such indemnification is
against public policy as expressed in the 1933 Act, and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer, or controlling person of the Registrant in the
successful defense of any action, suit, or proceeding) is asserted by such
director, officer, or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the 1933 Act and will be governed by the
final adjudication of such issue.
