under the Securities Act of 1933, as amended (the "Securities Act").

PART II.       INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

        Item 3.  Incorporation of Documents by Reference.

        Eclipsys Corporation (the "Registrant") is subject to the informational
and reporting requirements of Sections 13(a), 14 and 15(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and in accordance
therewith files reports, proxy statements and other information with the
Securities and Exchange Commission. The following documents, which are on file
with the Securities and Exchange Commission, are incorporated in this
Registration Statement by reference:

               (a) The Registrant's latest annual report filed pursuant to
Section 13(a) or 15(d) of the Exchange Act or the latest prospectus filed
pursuant to Rule 424(b) under the Securities Act, that contains audited

               (b) All other reports filed pursuant to Section 13(a) or 15(d) of
the Exchange Act since the end of the fiscal year covered by the document

        Item 4.  Description of Securities.

        Not applicable.

        Item 5.  Interests of Named Experts and Counsel.

        Not Applicable.

        Item 6.  Indemnification of Directors and Officers.

        Section 145 of the General Corporation Law of the State of Delaware
provides that a corporation has the power to indemnify a director, officer,
employee or agent of the corporation and certain other persons serving at the
request of the corporation in related capacities against amounts paid and
expenses incurred in connection with an action or proceeding to which he is or
is threatened to be made a party by reason of such position, if such person
shall have acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the corporation, and, in any criminal
proceeding, if such person had no reasonable cause to believe his conduct was
unlawful; provided that, in the case of actions brought by or in the right of
the corporation, no indemnification shall be made with respect to any matter as
to which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the adjudicating court determines that such
indemnification is proper under the circumstances.

        Article EIGHTH of the Registrant's Third Amended and Restated
Certificate of Incorporation (the "Certificate of Incorporation") provides that
no director of the Registrant shall be personally liable to the Registrant or
its stockholders for monetary damages for any breach of fiduciary duty as a
director, except to the extent that the Delaware General Corporation Law
prohibits the elimination or limitation of liability of directors for breaches
of fiduciary duty.

        Article NINTH of the Certificate of Incorporation provides that a
director or officer of the Registrant (a) shall be indemnified by the Registrant
against all expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement incurred in connection with any litigation or other legal
proceeding (other than an action by or in the right of the Registrant) brought,
or threatened to be brought, against him by virtue of his position as, or
agreement to become, a director or officer of the Registrant or by virtue of his
serving, or agreeing to serve, at the request of the Registrant, as a director,
officer, or trustee of, or in a similar capacity with, a corporation, trust or
other enterprise, if he acted in good faith and in a manner he reasonably
believed to be in, or not opposed to, the best interests of the Registrant, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful and (b) shall be indemnified by the Registrant
against all expenses (including attorneys' fees) and amounts paid in settlement
incurred in connection with any action by or in the right of the Registrant
brought, or threatened to be brought, against him by virtue of his position as,
or agreement to become, a director or officer of the Registrant or by virtue of
his serving, or agreeing to serve, at the request of the Registrant, as a
director, officer, or trustee of, or in a similar capacity with, a corporation,
trust or other enterprise, if he acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
Registrant, except that no indemnification shall be made with respect to any
matter as to which such person shall have been adjudged to be liable to the
Registrant, unless a court determines that, despite

                                        3


<PAGE>   4



such adjudication but in view of all of the circumstances, he is entitled to
indemnification of such expenses. Notwithstanding the foregoing, to the extent
that a director or officer has been successful, on the merits or otherwise,
including, without limitation, the dismissal of an action without prejudice, he
is required to be indemnified by the Registrant against all expenses (including
attorneys' fees) incurred in connection therewith. Expenses shall be advanced to
a director or officer at his request, provided that he undertakes to repay the
amount advanced if it is ultimately determined that he is not entitled to
indemnification for such expenses.

        The Registrant is required to provide the indemnification described
herein unless the officer or director has not met the applicable standard of
conduct required for indemnification. Whether the applicable standard of conduct
has been met shall be determined in each instance by (a) a majority vote of the
directors of the Registrant consisting of persons who are not at that time
parties to the action, suit or proceeding in question ("disinterested
directors"), whether or not a quorum, (b) a majority vote of a committee of
disinterested directors designated by majority vote of disinterested directors,
whether or not a quorum, (c) a majority vote of a quorum of the outstanding
shares of stock of all classes entitled to vote for directors, voting as a
single class, which quorum shall consist of stockholders who are not at that
time parties to the action, suit or proceeding in question, (d) independent
legal counsel (who may, to the extent permitted by law, be regular legal counsel
to the Registrant), or (e) a court of competent jurisdiction. In the event of a
determination that the director or officer did not meet the applicable standard
of conduct required for indemnification, or if the Registrant fails to make a
disposition within 60 days after written request for indemnification or
advancement of expenses to the Registrant is made by such person, such person is
permitted to petition the court to make an independent determination as to
whether such person is entitled to indemnification. As a condition precedent to
the right of indemnification, the director or officer must give the Registrant
notice of the action for which indemnity is sought and the Registrant has the
right to participate in such action or assume the defense thereof.

        Article NINTH of the Certificate of Incorporation further provides that
the indemnification provided therein is not exclusive, and provides that in the
event that the Delaware General Corporation Law is amended to expand the
indemnification permitted to directors or officers, the Registrant must
indemnify those persons to the fullest extent permitted by such law as so
amended.

        Item 7.  Exemption from Registration Claimed.

        Not applicable.

        Item 8.  Exhibits.

        The Exhibit Index immediately preceding the exhibits is attached hereto
and incorporated herein by reference.

        Item 9.  Undertakings.

        1.     The Registrant hereby undertakes:

                                        4


<PAGE>   5


               (a) To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement.

               (b) That, for the purpose of determining any liability under the
Securities 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.

               (c) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

        2. The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the 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.

        3. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities 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 Act and will
be governed by the final adjudication of such issue.

        The information required by Part I is included in documents sent or

under the Securities Act of 1933, as amended (the "Securities Act").

PART II.       INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

        Item 3.  Incorporation of Documents by Reference.

        Eclipsys Corporation (the "Registrant") is subject to the informational
and reporting requirements of Sections 13(a), 14 and 15(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and in accordance
therewith files reports, proxy statements and other information with the
Securities and Exchange Commission. The following documents, which are on file
with the Securities and Exchange Commission, are incorporated in this
Registration Statement by reference:

               (a) The Registrant's latest annual report filed pursuant to
Section 13(a) or 15(d) of the Exchange Act or the latest prospectus filed
pursuant to Rule 424(b) under the Securities Act, that contains audited
financial statements for the Registrant's latest fiscal year for which such
statements have been filed.

               (b) All other reports filed pursuant to Section 13(a) or 15(d) of
the Exchange Act since the end of the fiscal year covered by the document
referred to in (a) above.

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.

        Section 145 of the General Corporation Law of the State of Delaware
provides that a corporation has the power to indemnify a director, officer,
employee or agent of the corporation and certain other persons serving at the
request of the corporation in related capacities against amounts paid and
expenses incurred in connection with an action or proceeding to which he is or
is threatened to be made a party by reason of such position, if such person
shall have acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the corporation, and, in any criminal
proceeding, if such person had no reasonable cause to believe his conduct was
unlawful; provided that, in the case of actions brought by or in the right of
the corporation, no indemnification shall be made with respect to any matter as
to which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the adjudicating court determines that such
indemnification is proper under the circumstances.

        Article EIGHTH of the Registrant's Third Amended and Restated
Certificate of Incorporation (the "Certificate of Incorporation") provides that
no director of the Registrant shall be personally liable to the Registrant or
its stockholders for monetary damages for any breach of fiduciary duty as a
director, except to the extent that the Delaware General Corporation Law
prohibits the elimination or limitation of liability of directors for breaches
of fiduciary duty.

        Article NINTH of the Certificate of Incorporation provides that a
director or officer of the Registrant (a) shall be indemnified by the Registrant
against all expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement incurred in connection with any litigation or other legal
proceeding (other than an action by or in the right of the Registrant) brought,
or threatened to be brought, against him by virtue of his position as, or
agreement to become, a director or officer of the Registrant or by virtue of his
serving, or agreeing to serve, at the request of the Registrant, as a director,
officer, or trustee of, or in a similar capacity with, a corporation, trust or
other enterprise, if he acted in good faith and in a manner he reasonably
believed to be in, or not opposed to, the best interests of the Registrant, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful and (b) shall be indemnified by the Registrant
against all expenses (including attorneys' fees) and amounts paid in settlement
incurred in connection with any action by or in the right of the Registrant
brought, or threatened to be brought, against him by virtue of his position as,
or agreement to become, a director or officer of the Registrant or by virtue of
his serving, or agreeing to serve, at the request of the Registrant, as a
director, officer, or trustee of, or in a similar capacity with, a corporation,
trust or other enterprise, if he acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
Registrant, except that no indemnification shall be made with respect to any
matter as to which such person shall have been adjudged to be liable to the
Registrant, unless a court determines that, despite

                                        3

such adjudication but in view of all of the circumstances, he is entitled to
indemnification of such expenses. Notwithstanding the foregoing, to the extent
that a director or officer has been successful, on the merits or otherwise,
including, without limitation, the dismissal of an action without prejudice, he
is required to be indemnified by the Registrant against all expenses (including
attorneys' fees) incurred in connection therewith. Expenses shall be advanced to
a director or officer at his request, provided that he undertakes to repay the
amount advanced if it is ultimately determined that he is not entitled to
indemnification for such expenses.

        The Registrant is required to provide the indemnification described
herein unless the officer or director has not met the applicable standard of
conduct required for indemnification. Whether the applicable standard of conduct
has been met shall be determined in each instance by (a) a majority vote of the
directors of the Registrant consisting of persons who are not at that time
parties to the action, suit or proceeding in question ("disinterested
directors"), whether or not a quorum, (b) a majority vote of a committee of
disinterested directors designated by majority vote of disinterested directors,
whether or not a quorum, (c) a majority vote of a quorum of the outstanding
shares of stock of all classes entitled to vote for directors, voting as a
single class, which quorum shall consist of stockholders who are not at that
time parties to the action, suit or proceeding in question, (d) independent
legal counsel (who may, to the extent permitted by law, be regular legal counsel
to the Registrant), or (e) a court of competent jurisdiction. In the event of a
determination that the director or officer did not meet the applicable standard
of conduct required for indemnification, or if the Registrant fails to make a
disposition within 60 days after written request for indemnification or
advancement of expenses to the Registrant is made by such person, such person is
permitted to petition the court to make an independent determination as to
whether such person is entitled to indemnification. As a condition precedent to
the right of indemnification, the director or officer must give the Registrant
notice of the action for which indemnity is sought and the Registrant has the
right to participate in such action or assume the defense thereof.

        Article NINTH of the Certificate of Incorporation further provides that
the indemnification provided therein is not exclusive, and provides that in the
event that the Delaware General Corporation Law is amended to expand the
indemnification permitted to directors or officers, the Registrant must
indemnify those persons to the fullest extent permitted by such law as so
amended.

        Item 7.  Exemption from Registration Claimed.

        Not applicable.

        Item 8.  Exhibits.

        The Exhibit Index immediately preceding the exhibits is attached hereto
and incorporated herein by reference.

        Item 9.  Undertakings.

        1.     The Registrant hereby undertakes:

                                        4
5

               (a) To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement.

               (b) That, for the purpose of determining any liability under the
Securities 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.

               (c) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

        2. The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the 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.

        3. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities 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 Act and will
be governed by the final adjudication of such issue.

requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in Delray Beach, Florida on the 30th day of April, 1999.
