                                   ARTICLE IV

                                  CAPITAL STOCK

                  The Corporation is authorized to issue two classes of stock to
be designated, respectively, "Common Stock" and "Preferred Stock." The total
number of shares which the Corporation is authorized to issue is Seventy Million
(70,000,000) shares. Fifty Million (50,000,000) shares shall be designated as
Common Stock and Twenty Million (20,000,000) shares shall be designated as
Preferred Stock. The Common Stock and the Preferred Stock shall have the rights,
preferences and privileges set forth below. The Common Stock shall have a par
value of $0.001 and the Preferred Stock shall have a par value of $0.001.

         A. SERIES A CONVERTIBLE PREFERRED STOCK.

                  1. DESIGNATION AND NUMBER OF SHARES. There shall be hereby
created and established a series of Preferred Stock designated as "Series A
Convertible Preferred Stock" (the "Series A Preferred Stock"). The authorized
number of shares of Series A Preferred Stock shall be 6,512,316. Capitalized
terms used in this Section A and not otherwise defined in this Section A shall
have the meanings set forth in Section 10 below.

                  2. RANK.

                           (a) The Series A Preferred Stock shall with respect
to distributions of assets and rights upon the occurrence of a Liquidation rank
senior to (i) all classes of common stock of the Corporation (including, without
limitation, the Common Stock, par value $.001 per share, of the Corporation (the
"Common Stock")) and (ii) each other class or series of Capital Stock of the
Corporation hereafter created which does not expressly rank pari passu with or
senior to the Series A Preferred Stock (collectively with the Common Stock, the
"Junior Stock").

                  3. DIVIDENDS. The holders of shares of Series A Preferred
Stock shall not be entitled to receive dividends except in accordance with this
Section 3. If the Corporation declares and pays dividends on the Common Stock,
then, in that event, the holders of shares of Series A Preferred Stock shall be
entitled to share in such dividends on a pro rata basis, as if their shares had
been converted into shares of Common Stock pursuant to Section 7(a) immediately
prior to the record date for determining the stockholders of the Corporation
eligible to receive such dividends.

                                       2


                  4. LIQUIDATION PREFERENCE.

                           (a) Upon the occurrence of a Liquidation, the holders
of shares of Series A Preferred Stock shall be entitled to be paid for each
share of Series A Preferred Stock held thereby, out of the assets of the
Corporation legally available for distribution to its stockholders, an amount
per share in cash equal to (i) $2.850787 (the "Liquidation Preference") plus
(ii) all declared and unpaid dividends thereon, if any, to the date fixed for
such Liquidation, before any payment or distribution is made to any Junior
Stock. If the assets of the Corporation available for distribution to the
holders of Series A Preferred Stock shall be insufficient to permit payment in
full to such holders of the sums which such holders are entitled to receive in
such case, then all of the assets legally available for distribution to holders
of the Series A Preferred Stock shall be distributed among and paid to such
holders ratably in proportion to the amounts that would be payable to such
holders if such assets were sufficient to permit payment in full.

                           (b) After the holders of all shares of Series A
Preferred Stock shall have been paid in full the amounts to which they are
entitled under Section 4(a), the shares of Series A Preferred Stock shall not be
entitled to any further participation in any distribution of assets of the
Corporation, all the shares of Series A Preferred Stock shall become null and
void and the holders thereof shall have no rights thereunder, and the remaining
assets of the Corporation shall be distributed to the holders of Junior Stock.

                           (c) Written notice of a Liquidation stating a payment
or payments and the place where such payment or payments shall be payable, shall
be delivered in person, mailed by certified mail, return receipt requested,
mailed by overnight mail or sent by telecopier, not less than ten (10) days
prior to the earliest payment date stated therein, to the holders of record of
the Series A Preferred Stock, such notice to be addressed to each such holder at
its address as shown by the records of the Corporation.

                  5. REDEMPTION. The shares of Series A Preferred Stock shall
not be redeemed or subject to redemption, whether at the option of the
Corporation or any holder thereof, or otherwise.

                  6. VOTING RIGHTS; ELECTION OF DIRECTORS.

                           (a) The holders of Series A Preferred Stock shall be
entitled to vote on any matter required or permitted to be voted upon by the
stockholders of the Corporation.

                           (b) Each outstanding share of Series A Preferred
Stock shall entitle the holder thereof to vote, in person or by proxy, at a
special or annual meeting of stockholders, on all matters entitled to be voted
on by holders of Common Stock, voting together as a single class with the Common
Stock (and all other classes and series of stock of the Corporation entitled to
vote thereon with the Common Stock, if any). With respect to any such vote, each
share of Series A Preferred Stock shall entitle the holder thereof to cast that
number of votes per share as is equal to the number of votes that such holder
would be entitled to cast had such holder converted its shares of Series A
Preferred Stock into shares of Common Stock pursuant to Section 7(a) on the
record date for determining the stockholders of the Corporation eligible to vote
on any such matters.

                                       3


                           (c) At any time prior to the consummation of the
Initial Public Offering, if General Atlantic Partners 54, L.P. and/or any
affiliate thereof in the aggregate own (i) both (x) at least a majority of the
outstanding shares of Series A Preferred Stock and (y) shares of Common Stock
and/or Series A Preferred Stock or other securities of the Corporation
convertible into or exchangeable for shares of Common Stock that represent
(after giving effect to any adjustments) at least 10% of the total number of
shares of Common Stock outstanding on an as converted basis, then the holders of
the Series A Preferred Stock, voting as a separate class, shall be entitled to
elect two directors of the Corporation (the "Series A Directors") or (ii) both
(x) at least a majority of the outstanding shares of Series A Preferred Stock
and (y) shares of Common Stock and/or Series A Preferred Stock or other
securities of the Corporation convertible into or exchangeable for shares of
Common Stock that represent (after giving effect to any adjustments) less than
10% but at least 3% of the total number of shares of Common Stock outstanding on
an as converted basis, then the holders of the Series A Preferred Stock, voting
as a separate class, shall be entitled to elect one director of the Corporation.
The Series A Preferred Stock shall vote together as a single class with the
Common Stock (and all other classes and series of stock of the Corporation
entitled to vote thereon with the Common Stock, if any) with respect to the
election of all of the other directors of the Corporation. If the conditions set
forth in the first sentence of this Section 6(c) necessary for the holders of
the Series A Preferred Stock to vote as a separate class for the election of
directors are not satisfied, the Series A Preferred Stock shall vote together as
a single class with the Common Stock (and all other classes and series of stock
of the Corporation entitled to vote thereon, if any) with respect to the
election of all of the directors of the Corporation elected by such holders. At
any meeting held for the purpose of electing directors at a time when the Series
A Preferred Stock is entitled to vote as a separate class for the election of
the Series A Directors, (i) the presence in person or by proxy of the holders of
a majority of the shares of Series A Preferred Stock then outstanding shall
constitute a quorum of the Series A Preferred Stock for the election of the
Series A Director; (ii) the holders of Series A Preferred Stock shall be
entitled to cast one vote per share of Series A Preferred Stock in any such
election; and (iii) the Series A Directors shall each be elected by the
affirmative vote of the holders of a majority of the outstanding shares of
Series A Preferred Stock. Until the consummation of the Initial Public Offering,
a vacancy in a directorship held by either of the Series A Directors pursuant to
this Section 6(c) shall be filled only by vote or written consent of the holders
of the Series A Preferred Stock.

                  7. CONVERSION.

                           (a) OPTIONAL CONVERSION. Any holder of Series A
Preferred Stock shall have the right, at its option, at any time and from time
to time, to convert, subject to the terms and provisions of this Section 7, any
or all of such holder's shares of Series A Preferred Stock into such number of
fully paid and non-assessable shares of Common Stock as is equal to the product
of the number of shares of Preferred Stock being so converted multiplied by the
quotient of (i) the Liquidation Preference divided by (ii) the conversion price
of $2.850787 per share, subject to adjustment as provided in Section 7(e) (such
price, the "Conversion Price"), then in effect. Such conversion right shall be
exercised by the surrender of certificate(s) representing the shares of Series A
Preferred Stock to be converted to the Corporation at any time during usual
business hours at its principal place of business to be maintained by it (or
such other office or agency of the Corporation as the Corporation may designate
by notice in writing to the holders of Series A Preferred Stock), accompanied by
written notice that the holder elects



                                       4


to convert such shares of Series A Preferred Stock and specifying the name or
names (with address) in which a certificate or certificates for shares of Common
Stock are to be issued and (if so required by the Corporation) by a written
instrument or instruments of transfer in form reasonably satisfactory to the
Corporation duly executed by the holder or its duly authorized legal
representative and transfer tax stamps or funds therefor, if required pursuant
to Section 7(k). All certificates representing shares of Series A Preferred
Stock surrendered for conversion shall be delivered to the Corporation for
cancellation and canceled by it. No fractional shares of Common Stock or scrip
representing fractional shares shall be issued upon the conversion of shares of
Series A Preferred Stock. Instead of any fractional shares of Common Stock which
would otherwise be issuable upon conversion of shares of Series A Preferred
Stock, the Corporation shall pay to the holder of the shares of Series A
Preferred Stock that were converted a cash adjustment in respect of such
fractional shares in an amount equal to the same fraction of the market price
per share of the Common Stock (as determined in a reasonable manner prescribed
by the Board of Directors) at the close of business on the date of such
conversion.

                           (b) AUTOMATIC CONVERSION. (i) Immediately prior to
the closing of the Initial Public Offering or (ii) upon the conversion or
election to convert under Section 7(a) hereof into Common Stock of at least 67%
of all shares of Series A Preferred Stock issued hereunder, whichever is
earlier, each outstanding share of Series A Preferred Stock shall be
automatically converted, with no further action required to be taken by the
Corporation or the holder thereof, into the number of fully paid and
nonassessable shares of Common Stock equal to the product of the number of
shares of Series A Preferred Stock being converted multiplied by the quotient of
(x) the Liquidation Preference divided by (y) the Conversion Price then in
effect.

                  Immediately upon conversion as provided herein, each holder of
Series A Preferred Stock shall be deemed to be the holder of record of the
Common Stock issuable upon conversion of such holder's Series A Preferred Stock,
notwithstanding that the share register of the Corporation shall then be closed
or that certificates representing the Common Stock shall not then actually be
delivered to such Person. Upon notice from the Corporation, each holder of
Series A Preferred Stock so converted shall promptly surrender to the
Corporation at its principal place of business to be maintained by it (or at
such other office or agency of the Corporation as the Corporation may designate
by notice to the holders of Series A Preferred Stock) certificates representing
the shares so converted.

                           (c) As promptly as practicable after the surrender of
certificate(s) representing any shares of Series A Preferred Stock as to which
notice of conversion has been delivered to the Corporation, the Corporation
shall deliver to the holder of such shares so surrendered certificate(s)
representing the number of fully paid and nonassessable shares of Common Stock
into which such shares of Series A Preferred Stock have been converted in
accordance with the provisions of this Section 7. At the time of the surrender
of such certificate(s), the Person in whose name any certificate(s) for shares
of Common Stock shall be issuable upon such conversion shall be deemed to be the
holder of record of such shares of Common Stock on such date, notwithstanding
that the share register of the Corporation shall then be closed or that the
certificates representing such Common Stock shall not then be actually delivered
to such Person.

                                       5


                           (d) To the extent permitted by law, when shares of
Series A Preferred Stock are converted, all dividends declared and unpaid, if
any, on the shares of Series A Preferred Stock so converted to the date of
conversion shall be immediately due and payable; and, to the extent the
Corporation has legally available funds therefor, payment of such declared and
unpaid dividends shall accompany the shares of Common Stock issued upon such
conversion.

                           (e) ANTI-DILUTION ADJUSTMENTS. The Conversion Price,
and the number and type of securities to be received upon conversion of the
Series A Preferred Stock, shall be subject to adjustment as follows:

                           (i) DIVIDEND, SUBDIVISION, COMBINATION OR
RECLASSIFICATION OF COMMON STOCK. In the event that the Corporation shall at any
time or from time to time, prior to conversion of the Series A Preferred Stock,
(w) pay a dividend or make a distribution (other than a dividend or distribution
paid or made to holders of shares of Series A Preferred Stock, or in which
holders of such shares participate, in the manner provided in Section 3) on the
outstanding shares of Common Stock payable in Capital Stock, (x) subdivide the
outstanding shares of Common Stock into a larger number of shares, (y) combine
the outstanding shares of Common Stock into a smaller number of shares or (z)
issue any shares of its Capital Stock in a reclassification of the Common Stock
(other than any such event for which an adjustment is made pursuant to another
clause of this Section 7(e)), then, and in each such case, the Conversion Price
in effect immediately prior to such event shall be adjusted (and any other
appropriate actions shall be taken by the Corporation) so that the holder of any
share of Series A Preferred Stock thereafter surrendered for conversion shall be
entitled to receive the number of shares of Common Stock or other securities of
the Corporation that such holder would have owned or would have been entitled to
receive upon or by reason of any of the events described above, had such share
of Series A Preferred Stock been converted immediately prior to the record date
applicable to such event. An adjustment made pursuant to this Section 7(e)(i)
shall become effective retroactively to the close of business on the day upon
which such corporate action becomes effective.

                           (ii) ISSUANCE OF COMMON STOCK OR COMMON STOCK
EQUIVALENTS BELOW CONVERSION PRICE. In the event that the Corporation shall at
any time or from time to time, prior to conversion of the Series A Preferred
Stock, issue or sell any shares of Common Stock or Common Stock Equivalents at a
price per share (the "New Issue Price") that is less than the Conversion Price
then in effect as of the record date or Issue Date referred to in the following
sentence, as the case may be (the "Relevant Date") (treating the price per share
of Common Stock, in the case of the issuance of any Common Stock Equivalent, as
equal to (x) the sum of the price for such Common Stock Equivalent plus any
additional consideration payable (without regard to any anti-dilution
adjustments) upon the conversion, exchange or exercise of such Common Stock
Equivalent divided by (y) the number of shares of Common Stock initially
underlying such Common Stock Equivalent), other than (A) issuances or sales for
which an adjustment is made pursuant to another paragraph of this Section 7(e)
and (B) issuances of Common Stock in connection with an Excluded Transaction,
then, and in each such case, the Conversion Price then in effect shall be
adjusted by multiplying the Conversion Price in effect on the day immediately
prior to the Relevant Date by a fraction (I) the numerator of which shall be the
sum of the number of shares of Common Stock outstanding on the Relevant Date
plus the



                                       6


number of shares of Common Stock which the aggregate consideration received by
the Corporation for the total number of such additional shares of Common Stock
so issued would purchase at the Conversion Price on the Relevant Date (or, in
the case of Common Stock Equivalents, the number of shares of Common Stock into
which such Common Stock Equivalents may convert, exchange or be exercised plus
the number of shares of Common Stock which the aggregate amount of any
additional consideration initially payable upon conversion, exchange or exercise
of such Common Stock Equivalents would purchase at the Conversion Price on the
Relevant Date) and (II) the denominator of which shall be the sum of the number
of shares of Common Stock outstanding on the Relevant Date plus the number of
additional shares of Common Stock issued or to be issued (or, in the case of
Common Stock Equivalents, the maximum number of shares of Common Stock into
which such Common Stock Equivalents initially may convert, exchange or be
exercised). Such adjustment shall be made whenever such shares of Common Stock
or Common Stock Equivalents are issued or sold, and shall become effective
retroactively (x) in the case of an issuance to the stockholders of the
Corporation, as such, to a date immediately following the close of business on
the record date for the determination of stockholders entitled to receive such
shares of Common Stock or Common Stock Equivalents and (y) in all other cases,
to the date of such issuance (the "Issue Date"); PROVIDED, HOWEVER, that the
determination as to whether an adjustment is required to be made pursuant to
this Section 7(e)(ii) shall be made only upon the issuance of such shares of
Common Stock or Common Stock Equivalents, and not upon the issuance of any
security into which the Common Stock Equivalents convert, exchange or may be
exercised; and PROVIDED FURTHER, that if any Common Stock Equivalents (or any
portions thereof) which shall have given rise to an adjustment pursuant to this
Section 7(e)(ii) shall have expired or terminated without the exercise thereof
and/or if by reason of the terms of such Common Stock Equivalents there shall
have been an increase or increases, with the passage of time or otherwise, in
the price payable upon the exercise or conversion thereof, then the Conversion
Price hereunder shall be readjusted (but to no greater extent than originally
adjusted) in order to (A) eliminate from the computation any additional shares
of Common Stock corresponding to such Common Stock Equivalents as shall have
expired or terminated, (B) treat the additional shares of Common Stock, if any,
actually issued or issuable pursuant to the previous exercise of such Common
Stock Equivalents as having been issued for the consideration actually received
and receivable therefor and (C) treat any of such Common Stock Equivalents which
remain outstanding as being subject to exercise or conversion on the basis of
such exercise or conversion price as shall be in effect at the time.

                           (iii) CERTAIN DISTRIBUTIONS. In case the Corporation
shall at any time or from time to time prior to conversion of the Series A
Preferred Stock, distribute to all holders of shares of the Common Stock
(including any such distribution made in connection with a merger or
consolidation in which the Corporation is the resulting or surviving Person and
the Common Stock is not changed or exchanged) cash, evidences of indebtedness of
the Corporation or another issuer, securities of the Corporation or another
issuer or other assets (excluding dividends or distributions paid or made to
holders of shares of Series A Preferred Stock, or in which holders of such
shares participate, in the manner provided in Section 3, and dividends payable
in shares of Common Stock for which adjustment is made under another paragraph
of this Section 7(e) and any distribution in connection with an Excluded
Transaction) or rights or warrants to subscribe for or purchase securities of
the Corporation (excluding those distributions in respect of which an adjustment
in the Conversion Price is made pursuant to another paragraph of this Section
7(e) and any distribution in connection with an Excluded Transaction), then, and


                                       7


in each such case, the Conversion Price then in effect shall be adjusted (and
any other appropriate actions shall be taken by the Corporation) by multiplying
the Conversion Price in effect immediately prior to the date of such
distribution by a fraction (x) the numerator of which shall be the Current
Market Price of the Common Stock immediately prior to the date of distribution
less the then fair market value (as determined by the Board of Directors in the
exercise of their fiduciary duties) of the portion of the cash, evidences of
indebtedness, securities or other assets so distributed or of such rights or
warrants applicable to one share of Common Stock and (y) the denominator of
which shall be the Current Market Price of the Common Stock immediately prior to
the date of distribution (but such fraction shall not be greater than one);
PROVIDED, HOWEVER, that no adjustment shall be made with respect to any
distribution of rights or warrants to subscribe for or purchase securities of
the Corporation if the holder of shares of Series A Preferred Stock would
otherwise be entitled to receive such rights or warrants upon conversion at any
time of shares of Series A Preferred Stock into Common Stock. Such adjustment
shall be made whenever any such distribution is made and shall become effective
retroactively to a date immediately following the close of business on the
record date for the determination of stockholders entitled to receive such
distribution.

                           (iv) OTHER CHANGES. In case the Corporation at any
time or from time to time, prior to the conversion of the Series A Preferred
Stock, shall take any action affecting its Common Stock similar to or having an
effect similar to any of the actions described in any of Sections 7(e)(i)
through (ii) or Section 7(h) (but not including any action described in any such
Section) and the Board of Directors in good faith determines that it would be
equitable in the circumstances to adjust the Conversion Price as a result of
such action, then, and in each such case, the Conversion Price shall be adjusted
in such manner and at such time as the Board of Directors in good faith
determines would be equitable in the circumstances (such determination to be
evidenced in a resolution, a certified copy of which shall be mailed to the
holders of the shares of Series A Preferred Stock).

                           (V) DE MINIMIS ADJUSTMENTS. Notwithstanding anything
herein to the contrary, no adjustment in the Conversion Price shall be required
unless such adjustment would require a change of at least 1% in the Conversion
Price; provided, however, that any adjustments which by reason of this Section
7(e)(v) are not required to be made shall be carried forward and taken into
account in any subsequent adjustment.

                           (f) ABANDONMENT. If the Corporation shall take a
record of the holders of its Common Stock for the purpose of entitling them to
receive a dividend or other distribution, and shall thereafter and before the
distribution to stockholders thereof legally abandon its plan to pay or deliver
such dividend or distribution, then no adjustment in the Conversion Price shall
be required by reason of the taking of such record.

                           (g) CERTIFICATE AS TO ADJUSTMENTS. Upon any increase
or decrease in the Conversion Price, the Corporation shall within a reasonable
period (not to exceed 15 days) following the consummation of any of the
foregoing transactions deliver to each registered holder of Series A Preferred
Stock a certificate, signed by (i) the President or a Vice President of the
Corporation and (ii) the Treasurer or an Assistant Treasurer or the Secretary or
an Assistant Secretary of the Corporation, setting forth in reasonable detail
the event requiring the adjustment



                                       8


and the method by which such adjustment was calculated and specifying the
increased or decreased Conversion Price then in effect following such
adjustment.

                           (h) REORGANIZATION, RECLASSIFICATION. In case of any
capital reorganization or reclassification or other change of outstanding shares
of Common Stock (other than a change in par value, or from par value to no par
value, or from no par value to par value), the Corporation shall execute and
deliver to each holder of Series A Preferred Stock at least ten (10) Business
Days prior to effecting such capital reorganization or reclassification a
certificate stating that the holder of each share of Series A Preferred Stock
shall have the right thereafter to convert such share of Series A Preferred
Stock into the kind and amount of shares of stock or other securities, property
or cash receivable upon such capital reorganization or reclassification by a
holder of the number of shares of Common Stock into which such share of Series A
Preferred Stock could have been converted immediately prior to such capital
reorganization or reclassification, and provision shall be made therefor in the
agreement, if any, relating to such capital reorganization or reclassification.
Such certificate shall provide for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Section
7. The provisions of this Section 7(h) and any equivalent thereof in any such
certificate similarly shall apply to successive transactions.

                           (i) NOTICES. In case at any time or from time to
time:

                                    (w) the Corporation shall declare a dividend
(or any other distribution) on its shares of Common Stock;

                                    (x) the Corporation shall authorize the

breach of fiduciary duty as a director, notwithstanding any provision of law
imposing such liability. If the General Corporation Law is amended after
approval by the stockholders of this ARTICLE VI to authorize corporate action
further eliminating or limiting the personal liability of directors, then the
liability of a director of the Corporation shall be eliminated or limited to the
fullest extent permitted by the General Corporation Law of the State of
Delaware, as so amended. No amendment to or repeal of this provision shall apply
to or have any effect on the liability or alleged liability of any director of
the Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment.

                  Whenever a compromise or arrangement is proposed between this
Corporation and its creditors or any class of them and/or between this
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this Corporation or of any creditor or stockholder thereof or on



                                       14

under the provisions of Section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this Corporation under the provisions of Section 279 of Title 8 of the
Delaware Code, order a meeting of the creditors or class of creditors, and/or of

corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this corporation, as the case may be,
and also on this corporation.

                                   ARTICLE XI

                                 INDEMNIFICATION

                  The Corporation shall, to the fullest extent permitted by
Section 145 of the General Corporation Law, as amended from time to time,
indemnify each 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, by reason of the fact that he
is or was, or has agreed to become, a director or officer of the Corporation, or
is or was serving, or has agreed to serve, at the request of the Corporation, as
a director, officer or trustee of, or in a similar capacity with, another
corporation, partnership, joint venture, trust or other enterprise (including
any employee benefit plan) (all such persons being referred to hereafter as an
"Indemnitee"), or by reason of any action alleged to have been taken or omitted
in such capacity, against all expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by him or
on his behalf in connection with such action, suit or proceeding and any appeal
therefrom.

                  Indemnification may include payment by the Corporation of
expenses in defending an action or proceeding in advance of the final
disposition of such action or proceeding upon receipt of an undertaking by the
Indemnitee to repay such payment if it is ultimately determined that such person
is not entitled to indemnification under this ARTICLE XI, which undertaking may
be accepted without reference to the financial ability of such person to make
such repayment.

                  The Corporation shall not indemnify any such person seeking
indemnification in connection with a proceeding (or part thereof) initiated by
such person unless the initiation thereof was approved by the Board of Directors
of the Corporation.

                  The indemnification rights provided in this ARTICLE XI (i)
shall not be deemed exclusive of any other rights to which Indemnitees may be
entitled under any law, agreement or vote of stockholders or disinterested
directors or otherwise, and (ii) shall inure to the benefit of the heirs,
executors and administrators of such persons. The Corporation may, to the extent
authorized from time to time by its Board of Directors, grant indemnification
rights to other



                                       15


employees or agents of the Corporation or other persons serving the Corporation
and such rights may be equivalent to, or greater or less than, those set forth
in this ARTICLE XI."
