         ITEM 4.           DESCRIPTION OF SECURITIES.

         Not applicable. (The common stock is registered under Section 12 of the
Exchange Act.)

         ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

         ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Under Delaware General Corporation Law, a corporation shall have the
power to indemnify any person who was or is a party or is threatened to be made
a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the corporation) by reason of the fact that the person is
or was a director, officer, employee or agent of the corporation or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorney's fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by the person in
connection with such action, suit or proceeding if the person acted in good
faith and in a manner such person reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe the person's conduct was
unlawful.

         Although Delaware General Corporation Law permits a corporation to
indemnify any person referred to above against expenses (including attorney
fees) that are actually and reasonably incurred by such person ("Expenses"), in
connection with the defense or settlement of an action by or in the right of the
corporation, provided that such person acted in good faith and in a manner such
person reasonably believed to be in or not opposed to the corporation's best
interests, if such person has been judged liable to the corporation,
indemnification is for such expenses only permitted to the extent that the Court
of Chancery, or the court in which the action or suit was brought, determines
that, despite the adjudication of liability, such person is entitled to
indemnity for such Expenses as the Court of Chancery, or such other court, deems
proper.

         The determination, with respect to a person who is a director of
officer at the time of such determination, as to whether a person seeking
indemnification has met the required standard of conduct is to be made (i) by a
majority vote of the directors who are not parties to such action, suit or
proceeding, even though less than a quorum, or (ii) by a committee of such
directors designated by majority vote of such directors, even though less than a
quorum, or (iii) if there are no such directors, or if such directors so direct,
by independent legal counsel in a written opinion, or (iv) by the stockholders.

         Delaware General Corporation Law also provides that to the extent that
a present or former director or officer of a corporation has been successful on
the merits or otherwise defense of any action, suit or proceeding covered by the
statute, such person shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred by such person in connection therewith.
In addition, Delaware General Corporation Law provides for the general
authorization of advancement of a director's or officer's litigation expenses,
subject to an undertaking by such person to repay any such advancements if such
person is ultimately found not to have been entitled to reimbursement for such
expenses and that indemnification and advancement of expenses provided by the
statute shall not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any bylaw,
agreement, vote of stockholders or disinterested directors or otherwise.
TeleTech's Restated Certificate of Incorporation provides that TeleTech shall
indemnify its directors, officers, employees and agents to the fullest extent
permitted by Delaware General Corporation Law. TeleTech also is authorized to
secure


                                      -3-
<PAGE>

insurance on behalf of any person it is required or permitted to indemnify.
Pursuant to this provision, TeleTech maintains liability insurance for the
benefit of its directors and officers.

paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Exchange Act, that are incorporated by reference in this Registration Statement.

                  (2)      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.

                  (3)      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.

         (b)      The 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 that is incorporated by reference in 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
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 for 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 of whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

ITEM 4.           DESCRIPTION OF SECURITIES.

         Not applicable. (The common stock is registered under Section 12 of the
Exchange Act.)

         ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

         ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Under Delaware General Corporation Law, a corporation shall have the
power to indemnify any person who was or is a party or is threatened to be made
a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the corporation) by reason of the fact that the person is
or was a director, officer, employee or agent of the corporation or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorney's fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by the person in
connection with such action, suit or proceeding if the person acted in good
faith and in a manner such person reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe the person's conduct was
unlawful.

         Although Delaware General Corporation Law permits a corporation to
indemnify any person referred to above against expenses (including attorney
fees) that are actually and reasonably incurred by such person ("Expenses"), in
connection with the defense or settlement of an action by or in the right of the
corporation, provided that such person acted in good faith and in a manner such
person reasonably believed to be in or not opposed to the corporation's best
interests, if such person has been judged liable to the corporation,
indemnification is for such expenses only permitted to the extent that the Court
of Chancery, or the court in which the action or suit was brought, determines
that, despite the adjudication of liability, such person is entitled to
indemnity for such Expenses as the Court of Chancery, or such other court, deems
proper.

         The determination, with respect to a person who is a director of
officer at the time of such determination, as to whether a person seeking
indemnification has met the required standard of conduct is to be made (i) by a
majority vote of the directors who are not parties to such action, suit or
proceeding, even though less than a quorum, or (ii) by a committee of such
directors designated by majority vote of such directors, even though less than a
quorum, or (iii) if there are no such directors, or if such directors so direct,
by independent legal counsel in a written opinion, or (iv) by the stockholders.

         Delaware General Corporation Law also provides that to the extent that
a present or former director or officer of a corporation has been successful on
the merits or otherwise defense of any action, suit or proceeding covered by the
statute, such person shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred by such person in connection therewith.
In addition, Delaware General Corporation Law provides for the general
authorization of advancement of a director's or officer's litigation expenses,
subject to an undertaking by such person to repay any such advancements if such
person is ultimately found not to have been entitled to reimbursement for such
expenses and that indemnification and advancement of expenses provided by the
statute shall not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any bylaw,
agreement, vote of stockholders or disinterested directors or otherwise.
TeleTech's Restated Certificate of Incorporation provides that TeleTech shall
indemnify its directors, officers, employees and agents to the fullest extent
permitted by Delaware General Corporation Law. TeleTech also is authorized to
secure

                                      -3-
insurance on behalf of any person it is required or permitted to indemnify.
Pursuant to this provision, TeleTech maintains liability insurance for the
benefit of its directors and officers.

                  *        Filed herewith.

                  **       Filed as an exhibit to Newgen Results Corporation's
                  Registration Statement on Form S-1 (No. 333-62703) originally
                  filed on September 2, 1998, as amended through the date
                  hereof, and incorporated herein by reference.

         ITEM 9.           UNDERTAKINGS.

         (a)      The 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 Securities Act of 1933 (the "Securities Act");

                                      -4-
(ii)     To reflect in the prospectus any facts or
events arising after the effective date of the 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 the
Registration Statement; and

                           (iii)    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.

PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Exchange Act, that are incorporated by reference in this Registration Statement.

                  (2)      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.

                  (3)      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.

         (b)      The 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 that is incorporated by reference in 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
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 for 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 of whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
