                                   SCHEDULE I

                      RESOLUTION ESTABLISHING PREFERENCES

                                       of

                         4% CONVERTIBLE PREFERRED STOCK

         RESOLVED that there shall be a series of shares of the Class B
Preferred Stock of the Corporation designated "4% Convertible Preferred Stock";
that the number of shares of such series shall be 120,000 and that the rights
and preferences of such series (the "Convertible Preferred") and the
limitations or restrictions thereon, shall be as follows:

         1. Dividends. The holders of the Convertible Preferred shall be
entitled to receive out of any assets legally available therefor cumulative
dividends at the rate of $1.00 per share per annum, payable quarterly on March
31, June 30, September 30 and December 31 of each year, when and as declared by
the Board of Directors, in preference and priority to any payment of any
dividend on the Common Stock or any other class or series of stock of the
Corporation. Such dividends shall accrue on any given share commencing on and
including January 1, 2001, and shall accrue from day to day whether or not
earned or declared. If at any time dividends on the outstanding Convertible
Preferred at the rate set forth above shall not have been paid or declared and
set apart for payment with respect to all preceding periods, the amount of the
deficiency shall be fully paid or declared and set apart for payment, but
without interest, before any distribution, whether by way of dividend or
otherwise, shall be declared or paid upon or set apart for the shares of any
other class or series of stock of the Corporation.

         2. Liquidation Preference. In the event of any liquidation,
dissolution or winding up of the Corporation, either voluntary or involuntary,
the holders of the Convertible Preferred shall be entitled to receive, prior
and in preference to any distribution of any assets of the Corporation to the
holders of any other class or series of shares, the amount of $25 per share
plus any accrued but unpaid dividends (the "Liquidation Preference").

         3.       Forced Conversion.
                  -----------------

                  (a) The Corporation at its option may cause all outstanding
shares of the Convertible Preferred to be converted into Common Stock at any
time after the date of issuance, on at least 20 days' notice, at a conversion
price determined as set forth in Section 4 hereof (the "Conversion Price") as
of the date specified in such notice (the "Conversion Date") and otherwise on
the terms set forth in said Section 4; provided, however, that the Corporation
may not exercise such right of conversion unless the Closing Price (last trade
price) of the Common Stock as reported by Nasdaq for the 20 consecutive trading
days prior to the date the Conversion Notice (as defined in paragraph (b)
below) is mailed has not on any day been less than 120% of

                                       1
<PAGE>   3
the Conversion Cap (as defined in Section 4(d)(i) hereof) (subject to
adjustment for stock dividends, stock splits and reverse stock splits).

                  (b) At least 30 days, but not more than 60 days, prior to the
Conversion Date, written notice (the "Conversion Notice") shall be mailed,
first class postage prepaid, by the Corporation to each holder of record of the
Convertible Preferred, at the address last shown on the records of the
Corporation for such holder, notifying such holder of the conversion which is
to be effected, specifying the Conversion Date and calling upon each such
holder to surrender to the Corporation, in the manner and at the place
designated, a certificate or certificates representing the number of shares of
Convertible Preferred held by such holder. On or after the Conversion Date,
each holder of Convertible Preferred shall surrender to the Corporation the
certificate or certificates representing the shares of Convertible Preferred
owned by such holder as of the Conversion Date, in the manner and at the place
designated in the Conversion Notice, and thereupon the shares issuable upon
such conversion shall be delivered as provided in Section 4(b) hereof.

                  (c) On May 15, 2002 (the "Termination Date"), all then
outstanding shares of Convertible Preferred shall be automatically converted
into Common Stock at the Conversion Price and otherwise pursuant to the
applicable provisions set forth in Section 4 hereof.

         4. Optional Conversion. The holders of the Convertible Preferred shall
have optional conversion rights as follows:

                  (a) Right to Convert. Each share of Convertible Preferred
shall be convertible, at any time at the option of the holder thereof, into
such number of fully paid and nonassessable shares of Common Stock as is
determined by dividing (i) the Liquidation Preference of the Convertible
Preferred determined pursuant to Section 2 hereof on the date the notice of
conversion is given, by (ii) the Conversion Price determined as hereinafter
provided in effect on said date.

                  (b) Mechanics of Conversion. To convert shares of Convertible
Preferred into shares of Common Stock, the holder shall give written notice to
the Corporation (which notice may be given by facsimile transmission, confirmed
in due course by first class mail) that such holder elects to convert the same
and shall state therein the number of shares to be converted and the name or
names in which such holder wishes the certificate or certificates for shares of
Common Stock to be issued. Promptly thereafter the holder shall surrender the
certificate or certificates representing the shares to be converted, duly
endorsed, at the office of the Corporation or of any transfer agent for such
shares, or at such other place designated by the Corporation. The Corporation
shall, immediately upon receipt of such notice, issue and deliver to or upon
the order of such holder, against delivery of the certificates representing the
shares which have been converted, a certificate or certificates for the number
of shares of Common Stock to which such holder shall be entitled. The
Corporation shall effect such issuance within three business days of its
receipt of the notice of conversion and shall transmit the certificates by
messenger or overnight delivery service to reach the corporate address
designated by such holder

                                       2
<PAGE>   4
within three business days after the receipt of such notice. Notice of
conversion may be given by a holder at any time during the day up to 11:59 p.m.
New York time and such conversion shall be deemed to have been made immediately
prior to the close of business on the date such notice of conversion is given.
The person or persons entitled to receive the shares of Common Stock issuable
upon such conversion shall be treated for all purposes as the record holder or
holders of such shares of Common Stock at the close of business on such date.

                  (c) Payments in the Event of Non-Conversion. If, at any time,
the Corporation fails for any reason to deliver, within the three business day
period described above, certificates representing such number of shares of
Common Stock to which the holder is entitled upon such conversion, then the
Corporation shall pay to such holder $0 per share of such non-converted
Convertible Preferred for each calendar day of such non-delivery period on the
first day of each week following the date of any such failed delivery. In
addition, if (i) the Corporation fails for any reason to deliver, within such
three business day period specified above, shares of Common Stock to the holder
upon a conversion of the Convertible Preferred and (ii) after such three
business day period specified above with respect to such conversion, the holder
purchases (in an open market transaction or otherwise) shares of Common Stock
to make delivery upon a sale by the holder of the shares of Common Stock (the
"Sold Shares") which such holder anticipated receiving upon such conversion,
the Corporation shall pay such holder within two business days following
receipt of written notice of a claim pursuant to this Section 4(c) (in addition
to any other remedies available to the holder) the amount by which (x) such
holder's total purchase price (including brokerage commissions, if any) for the
shares of Common Stock so purchased exceeds (y) the net proceeds received by
such holder from the sale of the Sold Shares.

                  (d) Determination of Conversion Price.

                           (i)      The Conversion Price shall be $1.00 per
share. The Conversion Cap shall be $8.62 per share.

                           (ii)     If, during any period of consecutive
trading days provided for above, the Corporation shall declare or pay any
dividend on the Common Stock payable in Common Stock or in rights to acquire
Common Stock, or shall effect a stock split or reverse stock split, or a
combination, consolidation or reclassification of the Common Stock, then the
Conversion Price and the Conversion Cap shall be proportionately decreased or
increased, as appropriate, to give effect to such event.

                  (e) Distributions. If the Corporation shall at any time or
from time to time make or issue, or fix a record date for the determination of
holders of Common Stock entitled to receive, a dividend or other distribution
payable in securities of the Corporation or any of its subsidiaries other than
additional shares of Common Stock, then in each such event provision shall be
made so that the holders of Convertible Preferred shall receive, at the same
time as the holders of Common Stock, the securities of the Corporation which
they would have received had

                                       3
<PAGE>   5
they been the owners on such record date of the number of shares of Common
Stock issuable to them upon conversion on such record date.

                  (f) Certificates as to Adjustments. Upon the occurrence of
any adjustment or readjustment of the Conversion Price or the Conversion Cap
pursuant to this Section 4, the Corporation at its expense shall promptly
compute such adjustment or readjustment in accordance with the terms hereof
and, in the event the Corporation and the holders of the Convertible Preferred
shall not agree on such adjustment or readjustment, cause the independent
public accountant regularly employed to audit the financial statements of the
Corporation to make or verify such computation and prepare and furnish to each
holder of Convertible Preferred a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the written request at any
time of any holder of Convertible Preferred, furnish or cause to be furnished
to such holder a like certificate prepared by the Corporation setting forth (i)
such adjustments and readjustments, and (ii) the number of other securities and
the amount, if any, of other property which at the time would be received upon
the conversion of Convertible Preferred with respect to each share of Common
Stock received upon such conversion.

                  (g) Notice of Record Date. In the event of any taking by the
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any security or
right convertible into or entitling the holder thereof to receive additional
shares of Common Stock, or any right to subscribe for, purchase or otherwise
acquire any shares of stock of any class or any other securities or property,
or to receive any other right, the Corporation shall mail to each holder of
Convertible Preferred at least 10 days prior to the date specified therein, a
notice specifying the date on which any such record is to be taken for the
purpose of such dividend, distribution, security or right and the amount and
character of such dividend, distribution, security or right.

                  (h) Issue Taxes. The Corporation shall pay any and all issue
and other taxes, excluding any income, franchise or similar taxes, that may be
payable in respect of any issue or delivery of shares of Common Stock on
conversion of shares of Convertible Preferred pursuant hereto; provided,
however, that the Corporation shall not be obligated to pay any transfer taxes
resulting from any transfer requested by any holder in connection with any such
conversion.

                  (i) Reservation of Stock Issuable Upon Conversion. The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Convertible Preferred, such number of its
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all outstanding shares of the Convertible Preferred, subject to
the limitation set forth in Subsection (m) below, and if at any time the number
of authorized but unissued shares of Common Stock shall not be sufficient to
effect the conversion of all then outstanding shares of the Convertible
Preferred, the Corporation will take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to

                                       4
<PAGE>   6
such number of shares as shall be sufficient for such purpose, including,
without limitation, engaging in its best efforts to obtain the requisite
shareholder approval.

                  (j) Fractional Shares. No fractional shares shall be issued
upon the conversion of any share or shares of Convertible Preferred. All shares
of Common Stock (including fractions thereof) issuable upon conversion of more
than one share of Convertible Preferred by a holder thereof shall be aggregated
for purposes of determining whether the conversion would result in the issuance
of any fractional share. If, after the aforementioned aggregation, the
conversion would result in the issuance of a fraction of a share of Common
Stock, the Corporation shall, in lieu of issuing any fractional share, pay the
holder otherwise entitled to such fraction a sum in cash equal to the fair
market value of such fraction on the date of conversion (as determined in good
faith by the Board of Directors of the Corporation).

                  (k) Notices. Any notice required by the provisions of this
Section to be given to the holders of shares of Convertible Preferred shall be
deemed given if deposited in the United States mail, postage prepaid, and
addressed to each holder of record at its address appearing on the books of the
Corporation.

                  (l)      Reorganization or Merger.

                           (i)   Subject to clause (ii) below, in case of any
reorganization or any reclassification of the capital stock of the Corporation
or any consolidation or merger of the Corporation with or into any other
corporation or corporations or a sale of all or substantially all of the assets
of the Corporation to any other person, the holders of Convertible Preferred
shall thereafter have the right to receive upon conversion of their Convertible
Preferred shares, upon the basis and upon the terms and conditions specified
herein and in lieu of the shares of Common Stock immediately theretofore
issuable upon conversion, such stock, securities or other assets which the
holder would have been entitled to receive in such transaction had the
Convertible Preferred been converted immediately prior to such transaction, and
in any such case appropriate provisions shall be made with respect to the
rights and interests of the holders of the Convertible Preferred to the end
that the provisions hereof shall thereafter be applicable, as nearly as may be
practicable, in relation to
any securities thereafter deliverable upon the exercise hereof.

                           (ii)     In case of any reorganization or any
reclassification of the capital stock of the Corporation or any consolidation
or merger of the Corporation with or into any other corporation or corporations
or a sale of all or substantially all of the assets of the Corporation to any
other person, and where all, or a part, of the consideration paid in connection
with any such event to the holders of Common Stock consists of common stock of
the surviving corporation (or its direct or indirect parent corporation), such
surviving corporation (or its parent entity) shall establish, as of the
effective time of any such event, a new series or class of preferred securities
having terms essentially identical to those of the Convertible Preferred so as
to carry out fully the terms of this Section 4(l); provided, however, that (A)
the Conversion Cap shall be set at an amount equal to the Conversion Cap in
effect immediately prior to the effective time of such event multiplied by the
appropriate exchange ratio or conversion factor established in connection

                                       5
<PAGE>   7
with such event (subject to clause (B) below, the "Exchange Ratio"), (B) if
only part of such consideration paid in connection with such event consists of
such common stock, the Exchange Ratio shall be appropriately adjusted by the
Board of Directors of the Corporation, acting in good faith. The Corporation
shall not effect any transaction described in this Section 4(l) unless the
resulting successor or acquiring entity (if not the Corporation) assumes by
written instrument the obligations of the Corporation under this Certificate of
Designation including this Section 4(l).

                           (iii)  Notwithstanding clauses (i) and (ii) above,
in case of any consolidation or merger of the Corporation with or into any
other corporation or corporations or a sale of all or substantially all of the
assets of the Corporation to any other person, the Corporation may, at its
option, redeem the shares of Convertible Preferred, in whole and not in part,
on the date of the consolidation or merger of the Corporation with or into any
other corporation or corporations or a sale of all or substantially all of the
assets of the Corporation to any other person (the "Redemption Date"). In any
such case, the redemption price (the "Redemption Price") shall be an amount in
cash such that the holders of the Convertible Preferred shall have received,
through the Redemption Date, a compounded internal rate of return on their
investment in the Convertible Preferred of 20% per annum (using quarterly
compounding and including any dividends paid). Such Redemption Price shall be
payable on the Redemption Date. Notice of such Redemption Date shall be given
at least 30 days, but not more than 60 days, prior to the Redemption Date and
shall be given, mutatis mutandis, in the manner specified in Section 3 for the
giving of a Conversion Notice.

                  (m) Restricted Number of Conversion Shares. The Corporation
shall not be obligated to issue, in the aggregate, shares of Common Stock upon
conversion of the Convertible Preferred if issuance of such shares would (i)
constitute a breach of the Corporation's obligations under its agreements with
the NASD or Nasdaq or the rules of such organizations or (ii) cause the
Corporation to exceed the number of shares authorized in its charter or
articles of incorporation. If further issuances of shares of Common Stock upon
redemption of the Convertible Preferred would cause the Corporation to exceed
either of the limitations specified in clauses (i) and (ii) above, then so long
thereafter as such limitation shall continue to be applicable and any shares of
Convertible Preferred are submitted for conversion, such shares shall receive
in cash an amount equal to the current value of the Common Stock which such
shares would otherwise be entitled to receive upon conversion (such value per
share to be the closing price of such shares as reported by Nasdaq on the
Conversion Date), in lieu of the Common Stock such shares would otherwise be
entitled to receive upon conversion, and such shares will be deemed cancelled.
In the event that any such cash payment shall be required, the Corporation
shall so notify the holder by telephone, confirmed in writing by telecopy
(specifying the number of shares affected and the amount of cash to be paid),
on the same day that notice of conversion is given by such holder to the
Corporation. Payment of said cash amount shall be made no later than one
business day after the time specified in Section 4(b) for the delivery of
Common Stock upon conversion, and shall bear daily interest thereafter until
paid at a rate equal to the lesser of .1% or the highest rate permitted by law.
Such maximum number of shares of Common Stock shall be proportionately and
equitably adjusted in the event of stock splits, stock dividends, reverse stock
splits, reclassifications or other such events, in such manner as the

                                       6
<PAGE>   8
Board of Directors of the Corporation shall reasonably determine. The
Corporation shall, at any time upon the oral or written request of any holder,
forthwith inform such holder, orally or in writing, of the highest Common Stock
trade price at which any cash payment under this subsection (m) would then be
required.

                  (n) Reissuance of Certificates. In the event of an optional
conversion of Convertible Preferred pursuant to Section 4(a) hereof in which
less than all of the shares of Convertible Preferred of a particular
certificate are converted, the Corporation shall promptly cause to be issued
and delivered to the holder of such certificate a certificate representing the
remaining shares of Convertible Preferred which have not been so converted.

                  (o) Corporation to Prevent Dilution. If any event or
condition occurs as to which other provisions of this Section 4 are not
strictly applicable or if strictly applicable would not fairly protect the
conversion rights of the holders of the Convertible Preferred in accordance
with the essential intent and principles of such provisions, or which might
materially and adversely affect the conversion rights of any holder hereof,
then the Corporation, acting in good faith, shall make an adjustment in the
application of such provisions, or an addition thereto, in accordance with such
essential intent and principles, so as to protect such conversion rights as
aforesaid, including, without limitation, any adjustment necessary with respect
to the Conversion Price and the Conversion Cap so as to preserve the rights of
the holders of the Convertible Preferred.

         5. Other Provisions. For all purposes of this Resolution, the term
"date of issuance" and the terms "Closing" or "Closing Date" shall mean the day
on which shares of the Convertible Preferred are first issued by the
Corporation. Any provision herein which conflicts with or violates any
applicable usury law shall be deemed modified to the extent necessary to avoid
such conflict or violation. The term "Nasdaq" herein refers to the principal
market on which the Common Stock of the Corporation is traded. If the Common
Stock is listed on a securities exchange, or if another market becomes the
principal market on which the Common Stock is traded or through which price
quotations for the Common Stock are reported, the term "Nasdaq" shall be deemed
to refer to such exchange or other principal market.

         6. Restrictions and Limitations.

                  (a) The Corporation shall not undertake the following actions
without the consent, which consent shall not be unreasonably withheld in the
case of clause (ii) below, of the holders of a majority of the Convertible
Preferred, voting separately as a class: (i) modify its Certificate of
Incorporation or Bylaws, by merger or otherwise, so as to amend or change any
of the rights, preferences, or privileges of the Convertible Preferred, (ii) so
long as at least 20,000 shares of the Convertible Preferred remain outstanding,
authorize or issue any derivative or equity-linked security; provided, however,
that the Corporation may authorize or issue such securities pursuant to
qualified employee stock option plans, (iii) purchase or otherwise acquire for
value any Common Stock or other equity security of the Corporation either
junior or senior to or on a parity with the Convertible Preferred while there
exists any arrearage in the payment of

                                       7
<PAGE>   9
cumulative dividends hereunder; provided, however, that the Corporation may
effect purchases for the purpose of funding qualified employee stock option
plans, or (iv) pay or effect any dividend or distribution to shareholders of
cash, securities or any other items whatsoever; provided, however, that the
Corporation may effect one or more distributions of securities (and cash in
lieu of any fractional shares) in connection with the spin-off of its
non-financial business assets to shareholders.

                  (b) The holders of Convertible Preferred agree that after a
conversion of the Convertible Preferred (or any portion thereof) owned by a
holder, no holder will be permitted to sell any of its shares of the Common
Stock received in such conversion for a period of six (6) months following the
execution of the Preferred Stock Exchange Agreement dated as of the date
hereof, pursuant to which the Convertible Preferred was issued (the "Lock-up
Period"). After the expiration of the Lock-up Period and until May 15, 2002,
each holder will limit its sales of shares of Common Stock received upon
conversion of the Convertible Preferred to 75,000 shares per month. Between May
16, 2002 and May 15, 2003, each holder will be free to sell its shares either
publicly or privately, but in marketing any large blocks of shares of Common
Stock received upon conversion of the Convertible Preferred, the Corporation
and the holder(s) will cooperate in good faith to minimize the effects of any
such sales on the share price of the Common Stock, including, without
limitation, cooperating in the arrangement of block trades, where feasible.

         7.  No Five Percent Holders.

                  (a) The purpose of this Section is to prevent any holder from
holding over 5% of the Corporation's Common Stock without the consent of the
Board of Directors or 90 days' prior written notice, the holders having assured
the Corporation of their intentions, as of the Closing Date, to remain passive
investors and not to acquire any significant (that is, over 5%) block of the
Corporation's Common Stock without such consent or prior written notice.

                  (b) Notwithstanding anything to the contrary contained
herein, the Convertible Preferred shall not be convertible by a holder or the
Corporation to the extent (but only to the extent) that, if so converted the
holder would beneficially own in excess of 4.9% of the then outstanding shares
of Common Stock of the Corporation; provided, however, that the provisions of
this Section 7 shall not apply to a conversion effected pursuant to Section
3(c) hereof. To the extent this limitation applies, the determination of
whether any particular shares of Convertible Preferred shall be convertible
shall be in the sole discretion of the holder thereof and submission of the
Convertible Preferred for conversion shall be deemed to be the holder's
determination of whether such Convertible Preferred is convertible, subject to
such aggregate percentage limitation. No prior inability to convert Convertible
Preferred pursuant to this Section 7 shall have any effect on the applicability
of its provisions with respect to any subsequent determination of
convertibility. For the purposes of this Section 7, beneficial ownership and
all calculations including, without limitation, with respect to calculations of
percentage ownership, shall be determined in accordance with Section 13(d) of
the Securities Exchange Act of 1934, as amended, and the regulations
thereunder. Notwithstanding the

                                       8
<PAGE>   10
foregoing, each holder shall have the right to waive such restriction upon 90
days' prior notice to the Corporation. No transferee of Convertible Preferred
shall be bound by such restriction unless the transferee expressly so agrees.
The provisions of this Section 7 may be waived or implemented in a manner
otherwise than in strict conformity with the terms hereof with the approval of
the Board of Directors.

         8.  Voting Rights.

                  (a) General. The holders of Convertible Preferred will not
have any voting rights except as set forth herein or as otherwise from time to
time required by law. In connection with any right to vote, each holder of
Convertible Preferred will have one vote for each share held. Any shares of
Convertible Preferred held by the Corporation or any entity controlled by the
Corporation shall not have voting rights hereunder and shall not be counted in
determining the presence of a quorum.

                  (b) Contingent Voting Rights. So long as at least 20,000
shares of the Convertible Preferred shall remain outstanding, whenever (i)
dividends on the Convertible Preferred shall be in arrears in an amount equal
to at least two quarterly dividends (whether or not consecutive), or (ii) the
Corporation, for five consecutive trading days, shall not have sufficient
shares of Common Stock authorized and reserved for issuance to cover the number
of shares of Common Stock into which the Convertible Preferred shall then be
convertible hereunder, then, in the case of any of the events specified in the
foregoing clauses (i) and (ii), (A) the number of members of the Board of
Directors of the Corporation shall be increased to create such number of
vacancies as may be required to permit the holders of Convertible Preferred to
elect forthwith one member of the Board of Directors, or such other appropriate
action shall be taken to permit such election, effective as of the time of
election of such director as hereinafter provided and (B) the holders of the
Convertible Preferred (voting separately as a class) will have the exclusive
right to vote for and elect such additional director of the Corporation at any
meeting of stockholders of the Corporation at which directors are to be elected
held during the period the defaults specified in clauses (i) and (ii) above
continue and remain uncured. The right of the holders of the Convertible
Preferred to vote for such additional director shall terminate when the
applicable defaults specified in clauses (i) and (ii) above shall be cured. The
term of office of the director so elected shall terminate immediately upon the
termination of the right of the holders of the Convertible Preferred to vote
for such additional director.

         The foregoing right of holders of the Convertible Preferred with
respect to the election of one member of the Board of Directors may be
exercised at any annual meeting of stockholders or at any special meeting of
stockholders held for such purpose. If the right to elect a director shall have
accrued to the holders of the Convertible Preferred more than 90 days preceding
the date established for the next annual meeting of stockholders, the Chairman
of the Board of the Corporation shall, within 20 days after the delivery to the
Corporation at its principal office of a written request for a special meeting
signed by the holders of at least 25% of the Convertible Preferred then
outstanding, call a special meeting of the holders of the Convertible Preferred
to

                                       9
<PAGE>   11
be held within 30 days after the delivery of such request for the purpose of
electing such additional director.

         The holders of the Convertible Preferred, voting separately as a
class, shall have the right to remove without cause at any time and replace any
director such holders shall have elected pursuant to this Section 8(b).

                  (c)  Class Voting Rights. So long as the Convertible
Preferred is outstanding, the holders thereof shall also have the class voting
rights specified in Section 6.

         9. No Adverse Actions. The Corporation shall not in any manner,
whether by amendment of the Certificate of Incorporation (including, without
limitation, any Certificate of Designation), merger, reorganization,
recapitalization, consolidation, sales of assets, sale of stock, tender offer,
dissolution or otherwise, take any action, or permit any action to be taken,
solely or primarily for the purpose of increasing the value of any class of
stock of the Corporation if the effect of such action is to reduce the value or
security of the Convertible Preferred.
