-----
Securities (as defined below) unless, following the payment of preferential
amounts on all Senior Securities (as defined below), each Holder shall have
received the Liquidation Preference (as defined below) with respect to each
Preferred Share then held by such Holder. In the event that upon the occurrence
of a Liquidation Event, and following the payment of preferential amounts on all
Senior Securities (as defined below), the assets available for distribution to
the Holders and the holders of Pari Passu Securities are insufficient to pay the
Liquidation Preference with respect to all of the outstanding Preferred Shares
and the preferential amounts payable to such holders, the entire assets of the
Corporation shall be distributed ratably among the Preferred Shares and the
shares of Pari Passu Securities in proportion to the ratio that the preferential
amount payable on each such share (which shall be the Liquidation Preference in
the case of a Preferred Share) bears to the aggregate preferential amount
payable on all such shares.

          (ii) The "Liquidation Preference" with respect to a Preferred Share

----------
Corporation that are not Pari Passu Securities or Senior Securities. "Pari
                                                                      ----

with the Series B Preferred Stock in respect of redemption or distribution upon
liquidation. "Senior Securities" shall mean (i) any debt issued or assumed by

Preferred Shares held by such Holder into

                                      -6-
<PAGE>

such number of fully paid and non-assessable shares ("Conversion Shares") of the
                                                      -----------------
Common Stock as is determined in accordance with the terms hereof (a
"Conversion").
 ----------

     (b)  Conversion Notice.  In order to convert Preferred Shares, a Holder
          -----------------
shall send to the Corporation by facsimile transmission, at any time prior to
11:59 p.m., eastern time, on the date on which such Holder wishes to effect such
Conversion (the "Conversion Date"), (i) a notice of conversion in substantially
                 ---------------
the form of Exhibit A hereto (a "Conversion Notice") stating the number of
                                 -----------------
Preferred Shares to be converted, the applicable Conversion Price (as defined
below) and a calculation of the number of shares of Common Stock issuable upon
such Conversion and (ii) a copy of the certificate or certificates representing
the Preferred Shares being converted. The Holder shall thereafter send the
original of the Conversion Notice and of such certificate or certificates to the
Corporation. The Corporation shall issue a new certificate for Preferred Shares
in the event that less than all of the Preferred Shares represented by a
certificate delivered to the Corporation in connection with a Conversion are
converted. Except as otherwise provided herein, upon delivery of a Conversion
Notice by a Holder in accordance with the terms hereof, such Holder shall, as of
the applicable Conversion Date, be deemed for all purposes to be record owner of
the Common Stock to which such Conversion Notice relates. In the case of a
dispute between the Corporation and a Holder as to the calculation of the
Conversion Price or the number of Conversion Shares issuable upon a Conversion
(including without limitation the calculation of any adjustment to the
Conversion Price pursuant to Section 6 below), the Corporation shall issue to
such Holder the number of Conversion Shares that are not disputed within the
time periods specified in paragraph 4(e) below and shall submit the disputed
calculations to its independent accountant within two (2) Business Days of
receipt of such Holder's Conversion Notice. The Corporation shall cause such
accountant to calculate the Conversion Price as provided herein and to notify
the Corporation and such Holder of the results in writing no later than three
(3) Business Days following the Corporation's receipt of such Holder's
Conversion Notice (such 3/rd/ Business Day being referred to herein as the
"Disputed Share Calculation Date"). Such accountant's calculation shall be
 -------------------------------
deemed conclusive absent manifest error. The fees of any such accountant shall
be borne by the party whose calculations were most at variance with those of
such accountant.

     (c)  Number of Conversion Shares; Conversion Price.
          ---------------------------------------------

          (A)  The number of Conversion Shares to be delivered by the
Corporation pursuant to a Conversion shall be determined by dividing (i) the
aggregate Stated Value of the Preferred Shares to be converted by (ii) the
Conversion Price (as defined below) in effect on the applicable Conversion Date.

          (B)  "Conversion Price" shall be determined, subject to adjustment for
                ----------------
the events specified in Section 6 below, as follows: (A) during the period
beginning on the Issue Date and ending on the Trading Day (as defined below)
occurring immediately prior to the Effective Date (as defined below), the
Conversion Price shall be equal to the lower of (i) $20.00 (subject to
adjustment for the events specified in Section 6 hereof) and (ii) the Market
Price (as defined below) on the Issue Date (such lower price being referred to
herein as the "Initial Conversion Price"), (B) on and after
               ------------------------

                                      -7-
<PAGE>

the Effective Date (and subject to further adjustment as specified in clause (C)
below), the Conversion Price shall be equal to the lower of (i) the Initial
Conversion Price and (ii) the Market Price on the Effective Date and (C) on and
after the later to occur of (x) the ninetieth (90/th/) day following the
Effective Date and (y) the two hundred and seventieth (270/th/) day following
the Issue Date (the later to occur of (x) and (y) being referred to as the
"Determination Date"), the Conversion Price shall be equal to the lowest of (i)
 ------------------
the Initial Conversion Price, (ii) the Conversion Price determined pursuant to
clause (B) above, and (iii) the Market Price on the Determination Date;
provided, however, that the adjustment to the Conversion Price effected pursuant
--------  -------
to this clause (C) shall not occur in the event that the Market Price on the
Effective Date is at least 130% of the Initial Conversion Price. Notwithstanding
the foregoing, in no event will any Conversion Price calculated pursuant to
clauses (A), (B) or (C) above be lower than $8.00 (subject to adjustment for the
events specified in Section 6 hereof).

     (d)  Certain Definitions. "Business Day" means any day on which the New
          -------------------   ------------
York Stock Exchange and commercial banks located in the City of New York are
open for business. "Closing Bid Price" means, with respect to the Common Stock,
                    -----------------
the closing bid price for the Common Stock occurring on a given Trading Day on
the principal securities exchange or trading market where such security is
listed or traded as reported by Bloomberg Financial Markets or, if Bloomberg
Financial Markets is not then reporting such prices, by a comparable reporting
service of national reputation selected by the Corporation and reasonably
acceptable to each Holder of the then outstanding Preferred Shares
(collectively, "Bloomberg") or if the foregoing does not apply, the last
                ---------
reported bid price of such security in the over-the-counter market on the
electronic bulletin board for such security as reported by Bloomberg, or, if no
bid price is reported for such security by Bloomberg, the average of the bid
prices of all market makers for such security as reported in the "pink sheets"
by the National Quotation Bureau, Inc. (collectively, the "Applicable Reporting
                                                           --------------------
Entity"). If the Closing Bid Price cannot be calculated for such security on
--------
any of the foregoing bases, the Closing Bid Price of such security shall be the
fair market value as reasonably determined by an independent investment banking
firm selected by all of the Holders of Preferred Shares, and reasonably
acceptable to the Corporation, with the costs of such appraisal to be borne by
the Corporation. "Effective Date" means the day on which the Registration
                  --------------
Statement (as defined in the Registration Rights Agreement) is declared
effective by the Securities and Exchange Commission. "Market Price" means the
                                                      ------------
average Closing Bid Price for the Common Stock occurring during the period of
ten (10) consecutive Trading Days immediately preceding (but not including) the
date of determination (but in no event greater than the Closing Bid Price on the
Trading Day immediately preceding such date of determination); provided that if
the Market Price cannot be calculated as aforesaid, such Market Price shall be
the fair market value as reasonably determined by an investment banking firm
selected by the Corporation and reasonably acceptable to the Holders of a
majority of the Preferred Shares then outstanding, with the costs of such
appraisal to be borne by the Corporation. "Trading Day" means any day on which
                                           -----------

     (e)  Delivery of Conversion Shares.  Upon receipt of a Conversion Notice
          -----------------------------
from a Holder, the Corporation shall, on or before the close of business on the
later to occur of (i) the third (3rd)

<PAGE>

Business Day following the Conversion Date set forth in such Conversion Notice
and (ii) with respect to Conversion Shares that are the subject of a dispute as
described in paragraph 4(b) above, the Business Day immediately following the
Disputed Share Calculation Date (the applicable such Business Day being referred
to herein as a "Delivery Date"), issue and deliver or cause to be delivered to
                -------------
such Holder the number of Conversion Shares to which such Holder is entitled to
receive as provided herein. The Corporation shall effect delivery of Conversion
Shares to a Holder by, as long as the transfer agent for the Corporation (the
"Transfer Agent") participates in the Depository Trust Company ("DTC") Fast
 --------------                                                  ---
Automated Securities Transfer program ("FAST"), crediting the account of such
                                        ----
Holder or its nominee at DTC (as specified in the applicable Conversion Notice
or otherwise in writing) with the number of Conversion Shares required to be
delivered, no later than the close of business on such Delivery Date. In the
event that Transfer Agent is not a participant in FAST, or if Conversion Shares
are not otherwise eligible for delivery through FAST, or if a Holder so
specifies in a Conversion Notice or otherwise in writing on or before the
Delivery Date, the Corporation shall effect delivery of Conversion Shares by
delivering to the Holder or its nominee physical certificates representing such
shares, no later than the close of business on such Delivery Date. If any
Conversion would create a fractional Conversion Share, such fractional share
shall be disregarded and the number of Conversion Shares shall be the rounded to
the nearest whole number of shares. Conversion Shares delivered to a Holder

pledge or other disposition of such shares is covered by an effective
registration statement and such Holder represents in writing to the Corporation
that such shares have been or are being sold pursuant to such registration
statement, (B) such shares have been publicly sold pursuant to Rule 144
("Rule 144"), or (C) such shares can be sold pursuant to Rule 144(k) under
  --------
Securities Act of 1933, as amended (the "Securities Act"), or any successor
                                         --------------
rule or provision.

     (f)  Failure to Deliver Conversion Shares.
          ------------------------------------

          (i)  In the event that, as a result of any willful action or failure
to act on the part of the Corporation (whether under these Articles of
Amendment, under any other Transaction Document (as defined in the Securities
Purchase Agreement) or otherwise, including without limitation a failure by the
Corporation to have a sufficient number of shares of Common Stock authorized and
reserved for issuance pursuant to conversions of Preferred Shares), a Holder has
not received certificates (without any restrictive legend in the circumstances
described in clause (A), (B) or (C) of paragraph 4(e) above) representing the
number of Conversion Shares specified in the applicable Conversion Notice on or
before the Delivery Date therefor (a "Conversion Default"), and such failure to
                                      ------------------
deliver certificates continues for ten (10) Business Days following the delivery
of written notice thereof from such Holder (such tenth Business Day being
referred to herein as the "Conversion Default Date"), the Corporation shall pay
                           -----------------------
to such Holder payments ("Conversion Default Payments") in the amount of (i) "N"
                          ---------------------------
multiplied by (ii) the aggregate Stated Value of the Preferred Shares which are
-------------
the subject of such Conversion Default multiplied by (iii) one percent (1%),
                                       -------------
where "N" equals the number of days elapsed between the Conversion Default Date
and the earlier to occur of (i) the date on which all of the certificates
(without any restrictive legend in the circumstances described in clause (A),
(B) or (C) of paragraph 4(e) above) representing such

                                      -9-
<PAGE>

Conversion Shares are issued and delivered to such Holder, (ii) the date on
which such Preferred Shares are redeemed pursuant to the terms hereof and (iii)
the date on which a Withdrawal Notice (as defined below) is delivered to the
Corporation. Amounts payable hereunder shall be paid to the Holder in
immediately available funds on or before the fifth (5th) Business Day of the
calendar month immediately following the calendar month in which such amounts
have accrued.

          (ii)  In the event that a Holder has not received certificates
(without any restrictive legend in the circumstances described in clause (A),
(B) or (C) of paragraph 4(e) above) representing the Conversion Shares by the
tenth (10/th/) Business Day following a Conversion Default as a result of any
willful action or any failure to act on the part of the Corporation (whether
under these Articles of Amendment, under any other Transaction Document (as
defined in the Securities Purchase Agreement) or otherwise, including without
limitation a failure by the Corporation to have a sufficient number of shares of
Common Stock authorized and reserved for issuance pursuant to conversions of
Preferred Shares), such Holder may, upon written notice (a "Withdrawal Notice")
                                                            -----------------
delivered to the Corporation on such Business Day or on any Business Day
thereafter (unless, prior to the delivery of such notice, such Conversion Shares
are delivered to such Holder), withdraw its Conversion Notice with respect to
such Conversion Shares and regain its rights as a Holder of the Preferred Shares
that are the subject of such Conversion Default. In such event, the Conversion
Price in effect when such Preferred Shares are thereafter converted shall be
equal to the lowest Conversion Price or (if lower) Market Price occurring on or
after the date of such Conversion Notice reduced by one percent (1%) for each
day occurring during the period immediately following such 10th Business Day
until the day on which the such Holder delivers a Withdrawal Notice to the
Corporation; provided, however, that the maximum percentage by which such
Conversion Price may be reduced hereunder shall be fifty percent (50%). (For
example, if such Conversion Default were to continue for five days following
such 10th Business Day, such Conversion Price would be reduced by 5%; if for ten
days, by 10%; and for fifty days or more, 50%, so that the number of Conversion
Shares deliverable upon conversion of such Preferred Shares would be increased
proportionately). Upon delivery by a Holder of a Withdrawal Notice, such Holder
shall retain all of such Holder's rights and remedies with respect to the
Corporation's failure to deliver such Conversion Shares (including without
limitation the right to receive the cash payments specified in subparagraph
4(f)(i) above).

          (iii) In addition to any other remedies provided herein, each Holder
shall have the right to pursue actual damages for the Corporation's failure to
issue and deliver Conversion Shares on the applicable Delivery Date (including,
without limitation, damages relating to any purchase of shares of Common Stock
by such Holder to make delivery on a sale lawfully effected in anticipation of
receiving Conversion Shares upon Conversion, such damages to be in an amount
equal to (A) the aggregate amount paid by such Holder for the shares of Common
Stock so purchased minus (B) the aggregate Conversion Price for such Conversion
                   -----
Shares, and such Holder shall have the right to pursue all other remedies
available to it at law or in equity (including, without limitation, a decree of
specific performance and/or injunctive relief).

     (g)  Conversion at Maturity.  On the Determination Date, all Preferred
          ----------------------
Shares then held by the Holders (and with respect to which a Holder has not
submitted a Notice of Conversion) shall be automatically converted into the
number of shares of Common Stock equal to the Stated Value of such Preferred
Shares divided by the Conversion Price then in effect (a "Conversion at
       ----------                                         -------------
Maturity"); provided, however, that if, on the Determination Date, (i) the
--------
number of shares of Common Stock authorized, unissued and unreserved for all
other purposes, or held in the Corporation's treasury, is not sufficient to
effect the issuance and delivery of the number of Conversion Shares into which
all outstanding Preferred Shares are then convertible, (ii) the Common Stock is
not actively traded on either the Nasdaq SmallCap or National Market, (iii) a
Mandatory Redemption Event (as defined herein) has occurred and is continuing,
(iv) the conversion of a Holder's Preferred Shares pursuant to the Conversion at
Maturity would violate the provisions of Section 5 below; provided, however,
that in such event the Conversion at Maturity would apply solely to those
Preferred Shares the conversion of which would not violate Section 5 as of the
Determination Date and provided, further, that the determination on the
Determination Date of a Holder's beneficial ownership of Common Stock pursuant
to paragraph 5(b) above shall exclude any shares of Common Stock acquired by
such Holder otherwise than pursuant to the conversion or exercise of securities
outstanding on the day following the issuance of the Preferred Stock, or (v) the
Registration Statement (as defined in the Registration Rights Agreement) is not
effective and available for the resale of all Conversion Shares and Warrant
Shares issuable on the Determination Date upon the conversion or exercise of all
Preferred Shares and Warrants then outstanding (without regard to any
limitations on such conversion or exercise), each Holder shall have the option,
upon written notice to the Corporation, to regain its rights as a holder of
Preferred Shares (which, in the circumstances described in clause (iv) above,
would comprise the Preferred Shares not converted pursuant to the proviso of
clause (iv)), including without limitation, the right to convert such Preferred
Shares in accordance with the terms of paragraphs 4(a) through 4(f) hereof and,
upon delivery of such notice, such Preferred Shares shall not be subject to a
Conversion at Maturity hereunder until the thirtieth (30/th/) day following the
later of (a) the date on which the event specified in (i), (ii), (iii), (iv), or
(v) is no longer continuing and (b) the date on which the Corporation delivers
to each Holder written notice to such effect, and in such event, such thirtieth
day shall be deemed to be the Determination Date for purposes of these Articles
of Amendment; provided, however, that in the case of an event specified in
clause (iv), which (A) relates to the provisions of paragraph 5(a), the
Conversion Price for any conversions occurring after the happening of an event
(including without limitation the approval of the Corporation's stockholders
described in paragraph 5(a)) pursuant to which the applicability of such
paragraph to the conversion of Preferred Shares is eliminated shall be equal to
the lowest of (i) the Initial Conversion Price, (ii) the Conversion Price in
effect on the Determination Date, and (iii) the Market Price on the first
Trading Day on which paragraph 5(a) is no longer applicable, or (B) relates to
the provisions of paragraph 5(b), the Conversion Price for any conversions
occurring after the Determination Date shall be equal to the Conversion Price on
the Determination Date. In the event that the Registration Statement (as defined
in the Registration Rights Agreement) has not been effective and available to
each Holder for the resale of the maximum number of Conversion Shares and
Warrant Shares issuable upon conversion or exercise of such Holder's Preferred
Shares and Warrants, respectively (without regard to any

                                     -11-
<PAGE>

limitations on such conversion or exercise), for any period or periods on or
after the Effective Date and before the Determination Date (collectively, a
"Blackout Period"), the Determination Date (the "Original Determination Date")
shall be delayed for a period of days equal to the Blackout Period (the Trading
Day immediately following last day of such period being referred to herein as
the "Delayed Determination Date") and the Delayed Determination Date shall be
deemed to be the Determination Date for the purposes of these Articles of
Amendment; provided, however, that if the Determination Date is delayed because
a Blackout Period has occurred, the Conversion Price in effect on and after the
Original Determination Date (but prior to the Delayed Determination Date) shall
be equal to the lowest of (i) the Initial Conversion Price, (ii) the Conversion
Price in effect on the Trading Day immediately prior to the Original
Determination Date, and (iii) the Market Price on the Original Determination
Date and provided, further, that the Conversion Price in effect on the Delayed
Determination Date shall be equal to the lowest of (i) the Initial Conversion
Price, (ii) the Conversion Price in effect on the Trading Day immediately prior
to the Delayed Determination Date, and (iii) the Market Price on the Delayed
Determination Date. Notwithstanding the foregoing, in no event will any
Conversion Price calculated as set forth in this paragraph 4(g) be lower than
$8.00 (subject to adjustment for the events specified in Section 6 hereof). If a
Conversion at Maturity occurs, the Corporation and each Holder shall follow the
procedures for Conversion set forth in this Section 4, with the Determination
Date deemed to be the Conversion Date, except that the Holder shall not be
required to send a Conversion Notice as contemplated by paragraph 4(b).

5.   CONVERSION LIMITATIONS.
     ----------------------

     In no event shall a Holder be permitted to convert any Preferred Shares in
excess of the number of such shares, upon the Conversion of which:

     (a)  the number of Conversion Shares to be issued pursuant to such
Conversion, when added to the number of shares of Common Stock issued pursuant
to all prior Conversions of Preferred Shares and all prior exercises of the
Warrants by the Holders thereof, would exceed the maximum number of shares of
Common Stock issuable by the Corporation without stockholder approval in
compliance with the continued listing requirements of the Nasdaq SmallCap Market
(the "Cap Amount"), except that such limitation shall not apply in the event
      ----------
that (i) the Corporation obtains the approval of the holders of a majority of
the Corporation's Common Stock for the issuance of Common Stock in excess of the
Cap Amount (it being understood that any Holder whose Cap Allocation Amount (as
defined below) represents one hundred and seventy-five percent (175%) or less of
(A) the number of Conversion Shares and Warrant Shares into which the Preferred
Shares and Warrants then held by such Holder are convertible or exercisable at
the Conversion Price or the Exercise Price, as the case may be, then in effect
(without regard to any restrictions or limitations on such conversion or
exercise) plus (B) the number of Conversion Shares and Warrant Shares into which
          ----
such Holder has previously converted Preferred Shares and exercised the
Warrants, respectively, shall have the right to require the Corporation, upon
written notice to such effect, to seek such approval by means of a special
meeting of stockholders to be held as soon as practicable following the
Corporation's receipt of such notice, but in any case within ninety (90)

                                     -12-
<PAGE>

days following such receipt, and to recommend such approval to its stockholders
at such special meeting) or (ii) the Holders of a majority of the number of
Preferred Shares then outstanding (or, if no Preferred Shares are outstanding,
the holders of Warrants exercisable into majority of the Warrant Shares then
issuable) obtain an opinion of counsel reasonably satisfactory to the
Corporation that such approval is not required.  Until such approval or opinion
is obtained, no purchaser of Preferred Shares pursuant to the Securities
Purchase Agreement (each, a "Purchaser" and together the "Purchasers") shall be
                             ---------
issued, upon Conversion of the Preferred Shares, Conversion Shares in an amount
greater than the product of (A) the Cap Amount times (B) a fraction, the
                                               -----
numerator of which is the number of Preferred Shares issued to such Purchaser
pursuant to the Securities Purchase Agreement and the denominator of which is
the aggregate amount of all of the Preferred Shares issued to the Purchasers
pursuant to the Securities Purchase Agreement (the "Cap Allocation Amount").  In
                                                    ---------------------
the event that any Purchaser shall sell or otherwise transfer any of such
Purchaser's Preferred Shares or Warrants, the transferee shall be allocated a
pro rata portion of such Purchaser's Cap Allocation Amount. In the event that
any Holder converts all of such Holder's Preferred Shares and Warrants into a
number of Conversion Shares and Warrant Shares which, in the aggregate, is less
than such Holder's Cap Allocation Amount, then the difference between such
Holder's Cap Allocation Amount and the number of Conversion Shares and Warrant
Shares actually issued to such Holder shall be allocated to the respective Cap
Allocation Amounts of the remaining Holders of Preferred Shares on a pro rata
basis in proportion to the number of Preferred Shares then held by each such
Holder; or

     (b)  (x)  the number of shares of Common Stock beneficially owned by such
Holder (other than shares of Common Stock issuable upon conversion of such
Preferred Shares or which would otherwise be deemed beneficially owned except
for being subject to a limitation on conversion or exercise analogous to the
limitation contained in this paragraph 5(b)) plus (y) the number of shares of
                                             ----
Common Stock issuable upon the Conversion of such Preferred Shares, would be
equal to or exceed (z) 4.99% of the number of shares of Common Stock then issued
and outstanding. As used herein, beneficial ownership shall be determined in
accordance with Section 13(d) of the Securities Exchange Act of 1934, as
amended, and the rules thereunder. To the extent that the limitation contained
in this paragraph applies (and without limiting any rights the Corporation may
otherwise have), the Corporation may rely on the Holder's determination of
whether Preferred Shares are convertible pursuant to the terms hereof, the
Corporation having no obligation whatsoever to verify or confirm the accuracy of
such determination, and the submission of a Conversion Notice by the Holder
shall be deemed to be the Holder's representation that the Preferred Shares
specified therein are convertible pursuant to the terms hereof. This paragraph
may be amended by all of the Holders of Preferred Shares then outstanding only
with the consent of the holders of a majority of the shares of Common Stock then
outstanding. Nothing contained herein shall be deemed to restrict the right of a
Holder to convert Preferred Shares at such time as the Conversion thereof will
not violate the provisions of this paragraph 5(b).

6.   ADJUSTMENTS TO CONVERSION PRICE.
     -------------------------------

          (a)  Adjustment to Fixed Conversion Price Due to Stock Split, Stock
               --------------------------------------------------------------
Dividend, Etc.  If, prior to the Conversion of all of the Preferred Shares, (A)
-------------
the number of outstanding shares of Common Stock is increased by a stock split,
a stock dividend on the Common Stock, a reclassification of the Common Stock, or
other similar event, the Conversion Price shall be proportionately reduced,
which reduction shall be effected on the date on which the Corporation announces
such event; or (B) the Corporation issues Common Stock, whether upon the
exercise of rights, warrants, securities convertible or exercisable into Common
Stock or otherwise, at a price (the "Issue Price") that is less than the current
                                     -----------
Market Price thereof at the time of such issuance, the Conversion Price that
would otherwise be in effect on a particular date following such issuance shall
be proportionately reduced in order to account for the difference between the
Issue Price and such Market Price; provided, however, that if the Issue Price is
lower than the Conversion Price otherwise in effect on the date of such
issuance, such Conversion Price will be reduced to the lower of the amount
determined by this clause (B) and the amount determined by clause (D) below; (C)
the number of outstanding shares of Common Stock is decreased by a reverse stock
split, combination or reclassification of shares or other similar event, the
Conversion Price shall be proportionately increased, which increase shall be
effected on the date on which the Corporation announces such event; or (D) the
Corporation issues Common Stock, whether upon the exercise of rights, warrants,
securities convertible or exercisable into Common Stock or otherwise, at a price
that is lower than the Conversion Price in effect on any Conversion Date
following the date of such issuance, such Conversion Price shall be reduced to
such lower price.

     In no event shall any adjustment pursuant to clause (B) or clause (D) above
result in a Conversion Price that exceeds the Conversion Price that would
otherwise apply in the absence of such adjustment.

     (b)  Adjustment to Conversion Price During Reference Period.  If, prior to
          ------------------------------------------------------
the Conversion of all of the Preferred Shares, the number of outstanding shares
of Common Stock is increased or decreased by a stock split, a stock dividend on
the Common Stock, a combination, a reclassification of the Common Stock or other
similar event, and such event takes place during the reference period for the
determination of the Conversion Price for any Conversion thereof, the Conversion
Price shall be calculated giving appropriate effect to the stock split, stock
dividend, combination, reclassification or other similar event for all Trading
Days occurring during such reference period.

     (c)  Adjustment Due to Merger, Consolidation, Etc.  If, prior to the
          --------------------------------------------
Conversion of all of the Preferred Shares, there shall be any merger,
consolidation, business combination, tender offer, exchange of shares,
recapitalization, reorganization, redemption or other similar event, as a result
of which shares of Common Stock shall be changed into the same or a different
number of shares of the same or another class or classes of stock or securities
of the Corporation or another entity (an "Exchange Transaction"), then such
                                          --------------------
Holder shall (A) upon the consummation of such Exchange Transaction, have the
right to receive, with respect to any shares of Common Stock then held by such
Holder, or which such Holder is then entitled to receive pursuant to a
Conversion Notice previously delivered by such Holder (and without regard to
whether such shares contain a restrictive legend or are freely-tradable), the
same amount and type of consideration (including without

                                     -14-
<PAGE>

limitation, stock, securities and/or other assets) and on the same terms as a
holder of shares of Common Stock would be entitled to receive in connection with
the consummation of such Exchange Transaction (the "Exchange Consideration"),
                                                    ----------------------
and (B) upon the Conversion of Preferred Shares occurring subsequent to the
consummation of such Exchange Transaction (a "Subsequent Conversion"), have the
                                               --------------------
right to receive the Exchange Consideration which such Holder would have been
entitled to receive in connection with such Exchange Transaction had such shares
been converted immediately prior to such Exchange Transaction at the Conversion
Price applicable on the Conversion Date relating to such Subsequent Conversion,
and in any such case appropriate provisions shall be made with respect to the
rights and interests of such Holder to the end that the provisions hereof
(including, without limitation, provisions for the adjustment of the Conversion
Price and of the number of shares of Common Stock issuable upon a Conversion)
shall thereafter be applicable as nearly as may be practicable in relation to
any securities thereafter deliverable upon the Conversion of such Preferred
Shares. The Corporation shall not effect any Exchange Transaction unless (i) it
first gives to each Holder twenty (20) days prior written notice of such
Exchange Transaction (an "Exchange Notice"), and makes a public announcement of
                          ---------------
such event at the same time that it gives such notice (it being understood that
the filing by the Corporation of a Form 8-K for the purpose of disclosing the
anticipated consummation of the Exchange Transaction shall constitute an
Exchange Notice for purposes of this provision) and (ii) the resulting successor
or acquiring entity (if not the Corporation) assumes by written instrument the
obligations of the Corporation hereunder, including the terms of this
subparagraph 6(c), and under the Securities Purchase Agreement and the
Registration Rights Agreement.

     (d)  Distribution of Assets.  If the Corporation or any of its subsidiaries
          ----------------------
shall declare or make any distribution of cash, evidences of indebtedness or
other securities or assets (other than cash dividends or distributions payable
out of earned surplus or net profits for the current or the immediately
preceding year), or any rights to acquire any of the foregoing, to holders of
Common Stock (or to a holder, other than the Corporation, of the common stock of
any such subsidiary) as a partial liquidating dividend, by way of return of
capital or otherwise, including any dividend or distribution in shares of
capital stock of a subsidiary of the Corporation (collectively, a
"Distribution"), then each Holder shall be entitled to receive, at the same time
 ------------
as such assets are received by a holder of such stock, an amount and type of
such Distribution as though such Holder were a holder on the record date
therefor of a number of shares of Common Stock determined by dividing the
Liquidation Preference of the Preferred Shares held by such Holder on such
record date by the lower of the Market Price and the Conversion Price in effect
on such record date (such number of shares to be determined without regard to
any limitation on conversion of the Preferred Shares that may exist pursuant to
these Articles of Amendment or otherwise).

     (e)  Adjustment Due to Major Announcement.  If the Corporation (i) makes a
          ------------------------------------
public announcement that it intends to enter into a Change of Control
Transaction (as defined below) or (ii) any person, group or entity (including
the Corporation) publicly announces a tender offer, exchange offer or other
transaction to purchase 50% or more of the Common Stock (such announcement being
referred to herein as a "Major Announcement" and the date on which a Major
                         ------------------
Announcement is made, the "Announcement Date"), then, in the event that a Holder
                           -----------------
seeks

                                     -15-
<PAGE>

to convert Preferred Shares on or following the Announcement Date, the
Conversion Price shall, effective upon the Announcement Date and continuing
through the fifth (5th) Business Day following the earlier to occur of the
consummation of the proposed transaction or tender offer, exchange offer or
other transaction and the Abandonment Date (as defined below), be equal to the
lowest of (x) the Conversion Price in effect on the Announcement Date, (y) the
Market Price on the Announcement Date and (z) the Conversion Price that would
otherwise be in effect on the Conversion Date for such Preferred Shares.
"Abandonment Date" means with respect to any proposed transaction or tender
 ----------------
offer, exchange offer or other transaction for which a public announcement as
contemplated by this paragraph 6(e) has been made, the date upon which the
Corporation (in the case of clause (i) above) or the person, group or entity (in
the case of clause (ii) above) publicly announces the termination or abandonment
of the proposed transaction or tender offer, exchange offer or another
transaction which caused this paragraph 6(e) to become operative.

     (f)  Issuance of Other Securities.  If, at any time after the Closing Date,
          ----------------------------
the Corporation shall issue any securities which are convertible into or
exchangeable for Common ("Convertible Securities") either (i) at a conversion or
exchange rate based on a discount from the Market Price of the Common Stock at
the time of conversion or exercise or (ii) with a fixed conversion or exercise
price less than the Conversion Price, then, at the Holder's option: (x) in the
case of clause (i), the Conversion Price in respect of any conversion of the
Preferred Shares after such issuance shall be calculated utilizing the greatest
discount applicable to any such Convertible Securities; and (y) in the case of
clause (ii), the Conversion Price shall be proportionately reduced. If the
Corporation shall issue any Convertible Securities that are convertible into or
exchangeable for shares of Common Stock on a basis different from that of these
Articles of Amendment, each Holder may elect that the provisions of these
Articles of Amendment be revised to incorporate such different provisions with
respect to conversion or exchange, subject to the limitations of Section 5
hereof; provided, however, Purchaser may not select provisions on a non-
integrated basis which would have an inequitable result on the intent of this
provision.

     (g)  Adjustment Pursuant to Other Agreements. In addition to and without
          ---------------------------------------
limiting in any way the adjustments provided in this Section 6, the Conversion
Price shall be adjusted as may be required by the provisions of the Registration
Rights Agreement and/or by the provisions of the Securities Purchase Agreement.

     (h)  No Fractional Shares.  If any adjustment under this Section would
          --------------------
create a fractional share of Common Stock or a right to acquire a fractional
share of Common Stock, such fractional share shall be disregarded and the number
of shares of Common Stock issuable upon Conversion shall be rounded to the
nearest whole number of shares.

     (i)  Exceptions to Adjustment of Conversion Price.  No adjustment to the
          --------------------------------------------
Conversion Price will be made (i) upon the exercise or conversion of any
warrants, options or convertible securities issued and outstanding on the date
hereof in accordance with the terms of such securities as of such date; (ii)
upon the grant or exercise of any stock or options which may hereafter be

                                     -16-
<PAGE>

granted or exercised under any employee, consultant or director benefit plan of
the Corporation now existing or to be implemented in the future, so long as the
issuance of such stock or options is approved by a majority of the non-employee
members of the Board of Directors of the Corporation or a majority of the
members of a committee of non-employee directors established for such purpose;
(iii) upon the issuance of the Conversion Shares; or (iv) upon the exercise of
the Warrants.

7.   REDEMPTION.
     ----------

     (a)  Mandatory Redemption.  In the event that a Mandatory Redemption Event
          --------------------
(as defined below) occurs, each Holder shall have the right to require the
Corporation to redeem all or any portion of the Preferred Shares held by such
Holder (a "Mandatory Redemption") at the Mandatory Redemption Price (as defined
           --------------------
herein).  In order to exercise its right to effect a Mandatory Redemption, a
Holder must deliver a written notice (a "Mandatory Redemption Notice") to the
                                         ---------------------------
Corporation at any time on or before 11:59 p.m. (eastern time) on the third
(3/rd/) Business Day following the Business Day on which the Mandatory
Redemption Event to which such Mandatory Redemption Notice relates is no longer
continuing. The Mandatory Redemption Notice shall specify the effective date of
such Mandatory Redemption (the "Mandatory Redemption Date") and the number of
                                -------------------------
such shares to be redeemed.

     (b)  Mandatory Redemption Event.  Each of the following events shall be
          --------------------------
deemed a "Mandatory Redemption Event":
          --------------------------

          (i)   the Corporation fails, as a result of (x) not having a
sufficient number of shares of Common Stock authorized and reserved for
issuance, (y) failing to obtain the approval of its stockholders as required by
paragraph 5(a) hereof or by paragraph 4.12 of the Securities Purchase Agreement,
or (z) for any other reason within the control of the Corporation, to issue
shares of Common Stock to a Holder and deliver certificates representing such
shares (without any restrictive legend under the circumstances described in
paragraph 4(e) hereof) to such Holder as and when required by the provisions
hereof upon conversion of any Preferred Shares, and such failure continues for
ten (10) Business Days;

          (ii)  the Corporation breaches, in a material respect, any covenant or
other material term or condition of these Articles of Amendment, the Securities
Purchase Agreement, the Registration Rights Agreement, the Warrants or any other
agreement, document, certificate or other instrument delivered in connection
with the transactions contemplated thereby, and such breach continues for a
period of five (5) Business Days after written notice thereof to the Corporation
from a Holder;

          (iii) any material representation or warranty made by the Corporation
in the Securities Purchase Agreement, the Registration Rights Agreement, the
Warrants or any other agreement, document, certificate or other instrument
delivered in connection with the transactions contemplated hereby or thereby is
inaccurate or misleading in any material respect as of the date such
representation or warranty was made;

                                     -17-
<PAGE>

          (iv) (x)  the sale, conveyance or disposition of all or substantially
all of the assets of the Corporation, the effectuation of a transaction or
series of transactions in which more than 50% of the voting power of the
Corporation is disposed of, or the consolidation, merger or other business
combination of the Corporation with or into any other entity, immediately
following which the prior stockholders of the Corporation fail to own, directly
or indirectly, at least fifty percent (50%) of the surviving entity or (y) a
transaction or series of transactions in which any person acquires control of
the Corporation (each a "Change of Control Transaction"). For purposes hereof,
"control" shall mean, with respect to the Corporation, the ability to direct the
--------
business, operations or management of the Corporation, whether through an equity
interest therein or otherwise; and

          (v)  the Common Stock is not quoted on the Nasdaq SmallCap Market or
Nasdaq National Market or listed on the New York Stock Exchange or the American
Stock Exchange, or trading in the Common Stock on such market or exchange is
suspended and such suspension is in effect for more than five consecutive (5)
Trading Days, and such suspension or failure to be so quoted or listed occurs as
a result of any willful action or failure to act on the part of the Corporation.

     (c)  Mandatory Redemption Price.  The "Mandatory Redemption Price" shall be
          --------------------------        --------------------------
equal to the greater of (i) the Liquidation Preference of the Preferred Shares
being redeemed multiplied by one hundred and twenty five percent (125%) and (ii)
               -------------
an amount determined by dividing the Liquidation Preference of the Preferred
Shares being redeemed by the Conversion Price in effect on the Mandatory
Redemption Date and multiplying the resulting quotient by the average Closing
Trade  Price for the Common Stock on the five (5) Trading Days immediately
preceding (but not including) the Mandatory Redemption Date.

     (d)  Payment of Mandatory Redemption Price.
          -------------------------------------

          (i)   The Corporation shall pay the Mandatory Redemption Price to the
Holder exercising its right to redemption on the later to occur of (i) the fifth
(5th) Business Day following the Mandatory Redemption Date and (ii) the date on
which the Preferred Shares being redeemed are delivered by the Purchaser to the
Corporation for cancellation (the "Mandatory Redemption Payment Date").
                                   ---------------------------------

          (ii)  If Corporation fails to pay the Mandatory Redemption Price to
the Holder on or before the Mandatory Redemption Date, the Holder shall be
entitled to interest thereon, from and after the Mandatory Redemption Payment
Date until the Mandatory Redemption Price has been paid in full, at an annual
rate equal to the Default Interest Rate.

          (iii) If the Corporation fails to pay the Mandatory Redemption Price
within ten (10) Business Days of the Mandatory Redemption Date, then the Holder
shall have the right to regain its rights as a Holder of the Series B Preferred
Stock and, upon written notice to such effect from the Holder, the Corporation
shall return to such Holder the certificates representing the

                                     -18-
<PAGE>

Preferred Shares that were delivered to the Corporation in connection with such
Mandatory Redemption; in such event, the Conversion Price otherwise applicable
to future Conversions of the Preferred Shares shall be reduced by one percent
(1%) for each day beyond such 10th Business Day in which the failure to pay the
Mandatory Redemption Price continued until the date of such notice; provided,
however, that the maximum percentage by which such Conversion Price may be
reduced hereunder shall be fifty percent (50%).

8.   MISCELLANEOUS.
     -------------

     (a)  Transfer of Preferred Shares.  Upon notice to the Corporation, a
          ----------------------------
Holder may sell or transfer all or any portion of the Preferred Shares to any
person or entity as long as such sale or transfer is the subject of an effective
registration statement under the Securities Act or is exempt from registration
thereunder and otherwise is made in accordance with the terms of the Securities
Purchase Agreement. Notwithstanding the foregoing, no Holder shall knowingly and
voluntarily sell any Preferred Shares to an entity that is a competitor of the
Corporation. From and after the date of such sale or transfer, the transferee
thereof shall be deemed to be a Holder. Upon any such sale or transfer, the
Corporation shall, promptly following the return of the certificate or
certificates representing the Preferred Shares that are the subject of such sale
or transfer, issue and deliver to such transferee a new certificate in the name
of such transferee.

     (b)  Notices.  Except as otherwise provided herein, any notice, demand or
          -------
request required or permitted to be given pursuant to the terms hereof, the form
or delivery of which notice, demand or request is not otherwise specified
herein, shall be in writing and shall be deemed delivered (i) when delivered
personally or by verifiable facsimile transmission on or before 5:00 p.m.,
eastern time, on a Business Day or, if such day is not a Business Day, on the
next succeeding Business Day, (ii) on the next Business Day after timely
delivery to an overnight courier and (iii) on the day actually received if
deposited in the U.S. mail (certified or registered mail, return receipt
requested, postage prepaid), addressed to the parties as follows:

     (c)  Lost or Stolen Certificate.  Upon receipt by the Corporation of
          --------------------------
evidence of the loss, theft, destruction or mutilation of a certificate
representing Preferred Shares, and (in the case of loss, theft or destruction)
of indemnity or security reasonably satisfactory to the Corporation and the
Transfer Agent, and upon surrender and cancellation of such certificate if
mutilated, the Corporation shall execute and deliver to the Holder a new
certificate identical in all respects to the original certificate.

     (d)  No Voting Rights.  Except as provided by applicable law and
          ----------------
paragraph 8(g) below, the Holders of the Preferred Shares shall have no voting
rights with respect to the business, management or affairs of the Corporation;
provided that the Corporation shall provide each Holder with prior notification
of each meeting of stockholders (and copies of proxy statements and other
information sent to such stockholders).

     (e)  Remedies, Characterization, Other Obligations, Breaches and Injunctive
          ----------------------------------------------------------------------
Relief.  The remedies provided to a Holder in these Articles of Amendment shall
------
be cumulative and in addition to all other remedies available to such Holder
under these Articles of Amendment or under any Transaction Document (as defined
in the Securities Purchase Agreement), at law or in equity (including without
limitation a decree of specific performance and/or other injunctive relief), no
remedy contained herein shall be deemed a waiver of compliance with the
provisions giving rise to such remedy and nothing contained herein shall limit
such Holder's right to pursue actual damages for any failure by the Corporation
to comply with the terms of these Articles of Amendment. The Corporation agrees
with each Holder that there shall be no characterization concerning this
instrument other than as specifically provided herein. Amounts set forth or
provided for herein with respect to payments, conversion and the like (and the
computation thereof) shall be the amounts to be received by the Holder hereof
and shall not, except as expressly provided herein, be subject to any other
obligation of the Corporation (or the performance thereof). The Corporation
acknowledges that a material breach by it of its obligations hereunder will
cause irreparable harm to the Holders and that the remedy at law for any such
breach may be inadequate. The Corporation agrees, in the event of any such
breach or threatened breach, each Holder shall be entitled, in addition to all
other available remedies, to an injunction restraining any breach, without the
necessity of showing economic loss and without any bond or other security being
required.

                                     -20-
<PAGE>

     (f)  Failure or Delay not Waiver.  No failure or delay on the part of a
          ----------------------------
Holder in the exercise of any power, right or privilege hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise of any such power,
right or privilege preclude other or further exercise thereof or of any other
right, power or privilege.

     (g)  Protective Provisions.
          ---------------------

          So long as shares of Series B Preferred Stock are outstanding, the
Corporation shall not, without first obtaining the approval of the Holders of at
least two-thirds (2/3) of outstanding shares of Series B Preferred Stock:

               (i)   alter, change, modify or amend (x) the terms of the Series

               (vii) issue any Series B Preferred Stock except pursuant to the

                    AMENDMENT NO. 2 TO EMPLOYMENT AGREEMENT

        This Amendment No. 2 to Employment Agreement (this "AMENDMENT NO. 2") is
made effective as of September 16, 1999, by and between La Jolla Pharmaceutical
Company, a Delaware corporation (the "COMPANY") and Steven B. Engle
("EXECUTIVE").

        Executive and the Company are parties to that certain Employment
Agreement dated as of December 30, 1993 (the "AGREEMENT"), as amended by
Amendment No. 1 to Employment Agreement dated as of June 26, 1997 ("AMENDMENT
NO. 1") pursuant to which Executive is employed by the Company, and desire to
amend the Agreement as set forth herein in consideration of Executive's ongoing
employment. The Agreement and Amendment No. 1 are collectively referred to
herein as the "AMENDED AGREEMENT."

        Therefore, notwithstanding anything in the Amended Agreement to the
contrary, the Company and Executive hereby agree as follows:

        1. This Amendment No. 2 replaces Amendment No. 1 in its entirety, which
is superseded in all respects by this Amendment No. 2.

        2. Executive shall be employed by the Company as its President and Chief
Executive Officer, shall perform such duties as are consistent with such
position, and shall report to the Company's Board of Directors.

        3. As compensation for his services to the Company, Executive shall
receive a base salary of at least $273,000 per annum (as such amount may be
increased from time to time by the Company's Board of Directors, the "BASE
SALARY").

        4. (a) If Executive's employment with the Company is terminated by the
Company other than for cause as defined in Section 6.1 of the Agreement, or if a
Change in Control of the Company (as defined in the Company's 1994 Stock
Incentive Plan in its form as of the date hereof) occurs and Executive's
employment with the Company or its successor is terminated by the Company or its
successor, or if such a Change in Control occurs and Executive's employment with
the Company or its successor is terminated by Executive following any change in
Executive's title to any position other than President and CEO of the surviving
company, or any change in Executive's reporting responsibility such that he does
not report directly to the board of directors of the surviving company on all
matters, or any material reduction by the Company or its successor in
Executive's responsibilities, or any requirement that Executive's place of
employment be in other than the San Diego area, or any material breach by the
Company or its successor of the Agreement, as amended hereby, then, in addition
to any other benefits provided under the Agreement or this Amendment No. 2 that
may be applicable:

               (i) the Company (or its successor, as the case may be) shall pay
to Executive a severance payment (the "SEVERANCE PAYMENT") equal to the
then-current Base Salary for a period of twelve full calendar months from the
date of termination of Executive's employment (the "TERMINATION DATE"); and

<PAGE>   2

               (ii) the Company (or its successor, as the case may be) shall
continue, at its sole expense, all medical, dental and life insurance coverage
for Executive and his family on similar terms until the earlier of (A) twelve
full calendar months from the Termination Date, or (B) such time as Executive
receives similar paid coverage from another employer; and

               (iii) all employee stock options and other performance awards
granted to Executive before the Termination Date shall automatically vest and
become fully exercisable as of the Termination Date, notwithstanding any vesting
or performance conditions applicable thereto, and shall remain exercisable for a
period equal to the remaining term of the employee stock option or other
performance award as is provided by the plan or grant pursuant to which such
options or awards were received, provided that in no case will such options or
awards be exercisable beyond the duration of the original term thereof, and
provided further that nothing herein is intended to require the extension of the
exercise period of any option that qualifies as an incentive stock option under
the Internal Revenue Code and applicable regulations thereunder, and the
exercise period thereof shall not be extended beyond the termination date
otherwise provided by the award grant unless Executive, in his sole and
unqualified discretion, elects to forego incentive stock option treatment and
extend the exercise period thereof as provided herein; and

               (iv) if, within one (1) year of the Termination Date, employee
stock options granted to any executive officer of the Company (or its successor,
as the case may be) or non-employee directors' options granted to any member of
the Company's Board of Directors (or members of the board of directors of its
successor, as the case may be) are repriced, then, in addition to any other
benefits provided under the Agreement or this Amendment No. 2 that may be
applicable, the Company shall provide similar repricing at the election of the
Executive for all employee stock options granted to Executive before the
Termination Date that have not expired and remain unexercised. If necessary to
accomplish any extension, repricing or vesting of options under the Agreement,
as amended hereby, the Company will engage the Executive as a consultant on
customary and reasonable terms, to the extent required under applicable laws and
regulations and any documents governing the employee stock options to make
Executive eligible to have his employee stock options similarly repriced.
Notwithstanding anything to the contrary in this Amendment No. 2 or the plan or
awards under which employee stock options were or are granted to Executive, the
Company shall have no obligation to register Executive's repriced employee stock
options or the shares of Common Stock underlying such repriced options under the
Securities Act of 1933, as amended (the "Securities Act"), and shall have no
obligation to make Executive a consultant or advisor of the Company solely for
the purpose of making Executive's repriced employee stock options or shares of
Common Stock underlying such repriced options eligible for inclusion in any
registration statement under the Securities Act that the Company has otherwise
filed or is otherwise filing with respect to stock options granted to
individuals other than Executive or the shares of Common Stock underlying such
options.

        (b) If Executive's employment by the Company is terminated by Executive
for any reason other than under circumstances where the Company would be
entitled to terminate Executive's employment for cause as defined in Section 6.1
of the Agreement, all employee stock options granted to Executive before the
Termination Date that have vested or that vest upon or

                                       2
<PAGE>   3

following the Termination Date shall remain exercisable for a period of one year
following the Termination Date or such longer period as is provided by the plan
or grant pursuant to which such options were received, provided that in no case
will such options be exercisable beyond the duration of the original term
thereof, provided further that nothing herein is intended to require the
extension of the exercise period of any option that qualifies as an incentive
stock option under the Internal Revenue Code and applicable regulations
thereunder, and the exercise period thereof shall not be extended beyond the
termination date otherwise provided by the award grant unless Executive, in his
sole and unqualified discretion, elects to forego incentive stock option
treatment and extend the exercise period thereof as provided herein, and
provided further, that if Section 4(a)(iii) hereto is applicable, Section
4(a)(iii) hereto shall control.

           (c) The Severance Payment shall be payable in equal periodic
installments from the Termination Date consistent with the normal payroll
practices of the Company (or its successor, as the case may be), provided,
however, that Executive shall have the right, at any time in his discretion, to
receive the remaining balance of the Severance Payment in a lump sum discounted
to present value at a rate equal to the "Reference Rate" announced by Bank of
America NT & SA as of the time of Executive's election to receive a lump sum.
Executive shall exercise his right to receive a lump sum payment of the
Severance Payment by delivering written notice to the Company, and the Company
shall pay the lump sum within ten (10) days of receipt of such notice.

        6. (a) If a Corporate Transaction, as defined below, is consummated and
the day immediately prior to the effective date thereof Executive is employed by
the Company, or if a Corporate Transaction is consummated and Executive is
employed up to thirty (30) days prior to the effective date of the Corporate
Transaction and has substantially contributed towards making the Corporate
Transaction occur, then on the effective date of such Corporate Transaction or
such earlier date as determined by the Board of Directors of the Company in its
sole discretion, the Company shall pay to Executive a bonus payment equal to
$100,000.

           (b) For purposes of this Section 6, "Corporate Transaction" shall
mean the following:

               (i) any acquisition or series of related acquisitions resulting
in any person, entity or "group," within the meaning of Section 13(d)(3) or
14(d)(2) of the Exchange Act of 1934, as amended (the "Exchange Act")
beneficially owning (within the meaning of Rule 13d-3 promulgated under the
Exchange Act) forty percent (40%) or more of either the then outstanding shares
of Common Stock of the Company or the combined voting power of the Company's
then outstanding voting securities entitled to vote generally in the election of
directors; or

               (ii) a reorganization, merger or consolidation with any other
person, entity or corporation, other than a merger or consolidation which would
result in the owners of voting securities of the Company outstanding immediately
prior thereto continuing to own more than fifty percent (50%) of the combined
voting power of the voting securities of the Company and such other entity
outstanding immediately after such merger or consolidation, or

                                       3
<PAGE>   4

               (iii) the sale or other disposition by the Company, in one
transaction or a series of related transactions, of all or substantially all of
the Company's assets or all or substantially all of the Company's intellectual
property,

        provided that a Corporate Transaction shall not be deemed to have
occurred if the "person" described in the preceding provisions of this Section 6
is an underwriter or underwriting syndicate that has acquired the ownership of
50% or more of the combined voting power of the Company's then outstanding
voting securities solely in connection with a public offering of the Company's
securities.

        7. Notwithstanding anything to the contrary in any document awarding
employee stock options to Executive, the exercise price of all employee stock
options granted by the Company (or its successor, as the case may be) to
Executive prior or subsequent to the date hereof may be paid through conversion
of shares of the Common Stock of the Company (or its successor, as the case may
be) (the "Option Shares") underlying employee stock options granted to Executive
(a "Cashless Exercise"). Upon Cashless Exercise, Executive shall receive a
number of Option Shares equal to the number of Option Shares for which employee
stock options are being exercised less that number of Option Shares having an
aggregate value equal to the total exercise price of the employee stock options
being exercised by Executive that is due upon such exercise. The value of an
Option Share for purposes of Cashless Exercise shall be the average of the last
reported sale prices (or, if no sale has occurred, the closing price) of the
Option Shares on the Nasdaq National Market System ("NMS") or the principal
national securities exchange upon which the Option Shares are listed, as the
case may be, for each of the ten (10) trading days prior to the date of
Executive's employee stock option exercise, or, if the Option Shares are not
listed or admitted to trading on the NMS or any national securities exchange,
the average of the last quoted prices (or, if not so quoted, the average of the
high bid and low asked prices) in the over-the-counter market, as reported by
NASDAQ or such other system then in use, for each of the ten (10) trading days
prior to the date of Executive's employee stock option exercise, or, if the
Option Shares are not quoted by any such organization, the fair value of such
Option Shares on the date of exercise by Executive as determined in good faith
by the Board of Directors of the Corporation, which shall be conclusive for all
purposes.

        8. To the extent of any inconsistency between the text of the original
Agreement and this Amendment No. 2, Amendment No. 2 shall govern, provided that
nothing in Amendment No. 2 shall be construed to limit benefits to which
Executive is entitled under the Agreement in addition to those conferred by
Amendment No. 2, and to the extent not subsumed within the benefits provided by
Amendment No. 2, benefits provided under the Agreement shall remain in effect.

        IN WITNESS WHEREOF, Executive and the Company have entered into this
