     SECTION 1.02 Other Offices. The Corporation may also have an office or
offices at any other place or places within or without the State of Delaware as
the Board of Directors of the Corporation (the "Board") may from time to time
determine or the business of the Corporation may from time to time require.

                            MEETINGS OF STOCKHOLDERS

     SECTION 2.01 Annual Meetings. The annual meeting of Stockholders (as
defined in Section 2.03) of the Corporation for the election of directors of the
Corporation ("Directors"), and for the transaction of such other business as may
properly come before such meeting, shall be held at such place, date and time as
shall be fixed by the Board and designated in the notice or waiver of notice of
such annual meeting.

of common stock of the Corporation issued and outstanding ("Shares") entitled to
vote thereat, not less than 10 nor more than 90 days before the date of such
meeting. If mailed, such notice shall be deemed to be given when deposited in
the United States mail, postage prepaid, directed to the recordholder of Shares
(a "Stockholder") at such Stockholder's address as it appears on the records of
the Corporation. If, prior to the time of mailing, the Secretary shall have
received from any Stockholder a written request that notices intended for such
Stockholder are to be mailed to some address other than the address that appears
on the records of the Corporation, notices intended for such Stockholder shall
be mailed to the address designated in such request.

     (b) Notice of a special meeting of Stockholders may be given by the person
or persons calling the meeting, or, upon the written request of such person or
persons, such notice shall be given by the Secretary on behalf of such person or
persons. If the person or persons calling a special meeting of Stockholders give

meeting.

     SECTION 2.04 Waiver of Notice. Notice of any annual or special meeting of
Stockholders need not be given to any Stockholder who files a written waiver of
notice with the Secretary, signed by the person entitled to notice whether
before or after such meeting. Neither the business to be transacted at, nor the
purpose of, any meeting of Stockholders need to be specified in any written
waiver of notice thereof. Attendance of a Stockholder at a meeting, in person or
by proxy, shall constitute a waiver of notice of such meeting, except when such

beginning of the meeting, to the transaction of any business on the grounds that
the notice of such meeting was inadequate or improperly given.

     SECTION 2.05 Adjournments. Whenever a meeting of Stockholders, annual or
special, is adjourned to another date, time or place, notice need not be given
of the adjourned meeting if the date, time and place thereof are announced at
the meeting at which the adjournment is taken. If the adjournment is for more
than 30 days, or if after the adjournment a new record date is fixed for the
adjourned meeting, a notice of the adjourned meeting shall be given to each
Stockholder entitled to vote thereat. At the adjourned meeting, any business may
be transacted which might have been transacted at the original meeting. Any
previously scheduled meeting of the Stockholders may be postponed, and (unless

Incorporation") otherwise provides) any special meeting of the Stockholders may
be canceled, by resolution of the Board upon public notice given prior to the
date previously scheduled for such meeting of Stockholders.

     SECTION 2.06 Quorum. Except as otherwise provided by law or the Certificate
of Incorporation, the recordholders of a majority of the Shares entitled to vote
thereat, present in person or by proxy, shall constitute a quorum for the
transaction of business at all meetings of Stockholders, whether annual or
special. If , however, such quorum shall not be present in person or by proxy at
any meeting of Stockholders, the presiding officer at the meeting of the
Stockholders entitled to vote thereat may adjourn the meeting from time to time
in accordance with Section 2.05 hereof until a quorum shall be present in person
or by proxy.

each Share held of record by such Stockholder. Except as otherwise provided by
law or the Certificate of Incorporation, when a quorum is present at any meeting
of Stockholders, the vote of the recordholders of a majority of the Shares
constituting such quorum shall decide any question brought before such meeting.

     SECTION 2.08 Proxies. Each Stockholder entitled to vote at a meeting of

designated by the chairman of the meeting, shall act as secretary of the
meeting.

supervised by not less than two judges who shall decide all questions respecting
the qualification of voters, the validity of the proxies and the acceptance or
rejection of votes. The judges shall be appointed by the Board but if, for any
reason, there are less than two judges present and acting at any meeting, the
chairman of the meeting shall appoint an additional judge or judges so that
there shall always be at least two judges to act at the meeting.

     SECTION 2.11 List of Stockholders. A complete list of the Stockholders
entitled to vote at each meeting of Stockholders, arranged in alphabetical

the Secretary of the Corporation. To be timely, a Stockholder's notice must be
delivered to or mailed and received at the principal executive offices of the

the Stockholders, notice by the Stockholder to be timely must be received not
later than the close of business on the 10th day following the day on which such
notice of the date of the annual meeting was mailed or such public disclosure
was made. A Stockholder's notice to the Secretary shall set forth as to each
matter the Stockholder proposes to bring before the annual meeting (a) a brief
description of the business desired to be brought before the annual meeting and

contrary, no business shall be conducted at an annual meeting except in
accordance with the procedures set forth in this Section 2.12. The chairman of
an annual meeting shall, if the facts warrant, determine and declare to the
meeting that business was no properly brought before the meeting and in
accordance with the provisions of this Section 2.12, and if he should so
determine, he shall so declare to the meeting and any such business not properly
brought before the meeting shall not be transacted. Notwithstanding the
foregoing provisions of this Section 2.12, a Stockholder seeking to have a
proposal included in the Corporation's proxy statement shall comply with the
requirements of Regulation 14A under the Securities Exchange Act of 1934, as
amended (including, but not limited to, Rule 14a-8 or its successor provision.)

     SECTION 2.13 Notice of Stockholder Nominees. Only persons who are nominated
in accordance with the procedures set forth in these By-laws shall be eligible

be made at a meeting of Stockholders (a) by or at the direction of the Board or
(b) by any Stockholder entitled to vote for the election of Directors at the
meeting who complies with the notice procedures set forth in this Section 2.13.
Nominations by Stockholders shall be made pursuant to timely notice in writing
to the Secretary of the Corporation. To be timely, a Stockholder's notice shall
be delivered to or mailed and received at the principal executive offices of the
Corporation not less than sixty days nor more than ninety days prior to the
meeting; provided, however, that in the event that less than seventy days'


                                       -4-

 
By-laws of Ambac Financial Group, Inc.
Amended as of 7/11/97


notice or prior public disclosure of the date of the meeting is given or made to
Stockholders, notice by the Stockholder to be timely must be so received not
later than the close of business on the 10th day following the day on which such
notice of the date of the meeting was mailed or such public disclosure was made.
Such Stockholder's notice shall set forth (a) as to each person whom the
Stockholder proposes to nominate for election or re-election as a Director, all
information relating to such person that is required to be disclosed in
solicitations of proxies for election of directors, or is otherwise required, in
each case pursuant to Regulation 14A under the Securities Exchange Act of 1934,
as amended (including such person's written consent to being named in the proxy
statement as a nominee and to serving as a Director if elected); and (b) as to
the Stockholder giving the notice (i) the name and address, as they appear on
the Corporation's books, of such Stockholder and (ii) the class and number of
shares of the Corporation which are beneficially owned by such Stockholder. At
the request of the Board any person nominated by the Board for election as a
Director shall furnish to the Secretary that information required to be set
forth in a Stockholder's notice of nomination which pertains to the nominee. No
person shall be eligible for election as a Director unless nominated in
accordance with the procedures set forth in these By-laws. The chairman of the
meeting shall, if the facts warrant, determine and declare to the meeting that a
nomination was not made in accordance with the procedures prescribed by these
By-laws, and if he should so determine, he shall so declare to the meeting and
the defective nomination shall be disregarded.

     SECTION 2.14 Stockholders' Consent in Lieu of Meeting. (a) Consents to
Corporate Action. Any action which is required to be or may be taken at any
annual or special meeting of Stockholders, subject to the provisions of
Subsections (b) and (c) of this Section 2.14, may be taken without a meeting,
without prior notice and without a vote if consents in writing, setting forth
the action so taken, shall have been signed by the holders of the outstanding
Shares having not less than the minimum number of votes that would be necessary
to authorize or to take such action at a meeting at which all Shares entitled to
vote thereon were present and voted; provided. however, that prompt notice of
the taking of the corporate action without a meeting and by less than unanimous
written consent shall be given to those Stockholders who have not consented in
writing.

     (b) Determination of Record Date of Action by Written Consent. The record
date for determining Stockholders entitled to express consent to corporate
action in writing without a meeting shall be fixed by the Board. Any Stockholder
of record seeking to have the Stockholders authorize or take corporate action by
written consent without a meeting shall, by written notice to the Secretary,
request the Board to fix a record date. Upon receipt of such a request, the
Secretary shall place such request before the Board at its next regularly
scheduled meeting, provided, however, that if the Stockholder represents in such
request that he intends, and is prepared, to commence a consent solicitation as
soon as is permitted by the Securities Exchange Act of 1934, as amended, and the
regulations thereunder and other applicable law, the Secretary shall, as
promptly a practicable, call a special meeting of the Board, which meeting shall
be held as


                                      -5-

 
By-laws of Ambac Financial Group, Inc.
Amended as of 7/11/97


promptly as practicable. At such regular or special meeting, the Board shall fix
a record date as provided in Section 213(a) (or its successor provision) of the
General Corporation Law of the State of Delaware (the "General Corporation
Law"). Should the Board fail to fix a record date as provided for in this
Subsection (b), then the record date shall be the day on which the first written
consent is expressed.

     (c) Procedures for Written Consent. In the event of the delivery to the
Corporation of a written consent or consents purporting to represent the
requisite voting power to authorize or take corporate action and/or related
revocations, the Secretary shall provide for safekeeping of such consents and
revocations and shall, as promptly as practicable, engage nationally recognized
independent judges of election for the purpose of promptly performing a
ministerial review of the validity of the consents and revocations. No action by
written consent and without a meeting shall be effective until such judges have
completed their review, determined that the requisite number of valid and
unrevoked consents has been obtained to authorize or take action specified in
the consents, and certified such determination for entry in the records of the
Corporation kept for the purpose of recording the proceedings of meetings of
Stockholders.

shall be managed by the Board, which may exercise all such powers of the

is elected and qualified, or until his earlier death or resignation or removal
in the manner hereinafter provided.

     SECTION 3.03 Resignation. Any Director may resign at any time by giving
written notice to the Board, the Chairman or the Secretary. Such resignation

the case may be. Unless otherwise specified therein, acceptance of such
resignation shall not be necessary to make it effective.

of the recordholders of Shares pursuant to Section 2.14 hereof.

     SECTION 3.05 Vacancies. Vacancies occurring on the Board as a result of the
removal of Directors without cause may be filled only by vote of the

of Directors, or by written consent of such recordholders pursuant to Section
2.14 hereof. Vacancies occurring on the Board for any other reason, including,
without limitation, vacancies occurring as a result of the creation of new
directorships that increase the number of Directors, may be filled by such vote
or written consent or by vote of the Board or by written consent of the
Directors pursuant to Section 3.08 hereof. If the number of Directors then in
office is less than quorum, such other vacancies may be filled by vote of a

Stockholders and until his successor shall be elected and qualified.

other organization and stated meeting and of all special meetings of the Board,

agent thereunto duly authorized by the Board, may authorize the issue of a new
certificate in place of any certificate theretofore issued and alleged to have
been mutilated, lost, stolen or destroyed, upon the surrender of the mutilated
certificate or, in the case of loss, theft or destruction of the certificate,
upon satisfactory proof of such loss, theft or destruction, and the Board may,
in its discretion, require, and its transfer agents and registrars may so
require, the recordholder of the Shares evidenced by the lost, stolen or
destroyed certificate or his legal representative to give the Corporation a bond
sufficient to indemnify the Corporation against any claim made against it on
account of the alleged loss, theft or destruction of any such certificate or the
issuance of such new certificate.

order that the Corporation may determine the Stockholders entitled to notice of
or to vote at any meeting of Stockholders or any adjournment thereof, or to
express consent to, or to dissent from, corporate action in writing without a
meeting, or entitled to receive payment of any dividend or other distribution or
allotment of any rights, or entitled to exercise any rights in respect of any
change, conversion or exchange of stock, or for the purpose of any other lawful
action, the Board may fix, in advance, a record date, which shall not be more
than 60 nor less than 10 days before the date of such meeting, nor more than 60
days prior to any other such action. A determination of the Stockholders
entitled to notice of or to vote at a meeting of Stockholders shall apply to any
adjournment of such meeting; provided, however, that the Board may fix a new
record date for the adjourned meeting.

                          INDEMNIFICATION AND INSURANCE

     SECTION 9.01 Indemnification. (a) The Corporation shall 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 he 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 attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding 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
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
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
reasonable cause to believe that his conduct was unlawful.

     (b) The Corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor by
reason of the fact that he 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)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit 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
Corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the Corporation unless and only to the extent that the Court of
Chancery of the State of Delaware or the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is


                                      -15-

 
By-laws of Ambac Financial Group, Inc.
Amended as of 7/11/97


fairly and reasonably entitled to indemnity for such expenses which the Court of
Chancery or such other court shall deem proper.

     (c) To the extent that a director, officer, employee or agent of the
Corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in Section 9.01(a) and (b) of these
By-laws, or in defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.

     (d) Any indemnification under Section 9.01(a) and (b) of these By-laws
(unless ordered by a court) shall be made by the Corporation only as authorized
in the specific case upon a determination that indemnification of the director,
officer, employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in Section 9.01(a) and (b) of these
By-laws. Such determination shall be made (i) by the Board by a majority vote of
a quorum consisting of directors who were not parties to such action, suit or
proceeding, or (ii) if such a quorum is not obtainable, or, even if obtainable,
a quorum of disinterested directors so directs, by independent legal counsel in
a written opinion, or (iii) by the stockholders of the Corporation.

     (e) Expenses (including attorneys' fees) incurred by an officer or director
in defending any civil, criminal, administrative or investigative action, suit
or proceeding may be paid by the Corporation in advance of the final disposition
of such action, suit or proceeding upon receipt of an undertaking by or on
behalf of such director or officer to repay such amount if it shall ultimately
be determined that he is not entitled to be indemnified by the Corporation
pursuant to this Article IX. Such expenses (including attorneys' fees) incurred
by other employees and agents may be so paid upon such terms and conditions, if
any, as the Board deems appropriate.

     (f) The indemnification and advancement of expenses provided by, or granted
pursuant to, other Sections of this Article IX shall not be deemed exclusive of
any other rights to which those seeking indemnification or advancement of
expenses may be entitled under any law, by-law, agreement, vote of stockholders
or disinterested directors or otherwise, both as to action in an official
capacity and as to action in another capacity while holding such office.

     (g) For purposes of this Article IX, references to "the Corporation" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, employees or agents so that any
person who is or was a director, officer, employee or agent of such constituent
corporation, or is or was serving at the request of such constituent corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, shall stand in the same position under
the provisions of this Article IX with respect to the

resulting or surviving corporation as he would have with respect to such
constituent corporation if its separate existence had continued.

     (h) For purposes of this Article IX, references to "other enterprises"
shall include employee benefit plans, references to "fines" shall include any
excise taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the Corporation" shall include any
service as a director, officer, employee or agent of the Corporation which
imposes duties on, or involves service by, such director, officer, employee or
agent with respect to any employee benefit plan, its participants, or
beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not
opposed to the best interests of the Corporation" as referred to in this Article
IX.

     (i) The indemnification and advancement of expenses provided by, or granted
pursuant to, this Article IX shall, unless otherwise provided when authorized or
ratified, continue as to a person who has ceased to be a director, officer,
employee or agent and shall inure to the benefit of the heirs, executors and
administrators of such a person.

     SECTION 9.02 Insurance for Indemnification. The Corporation may purchase
and maintain insurance on behalf of any person who 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 any
liability asserted against him and incurred by him in any such capacity, or
arising out of his status as such, whether or not the Corporation would have the
power to indemnify him against such liability under the provisions of Section
145 of the General Corporation Law.
