                                       1
   2

        (A)    Series A Convertible Preferred Stock

               The following is a statement of the designations, powers,
privileges, preferences and relative, participating, optional or other special
rights, and the qualifications, limitations or restrictions relating to the
Series A Convertible Preferred Stock:

               (1)  Number and Designation. 8,250,000 shares of the Preferred
Stock of the Corporation shall be designated as Series A Convertible Preferred
Stock (the "SERIES A PREFERRED STOCK"). Each share of Series A Preferred Stock
shall rank equally in all respects and shall be subject to the following
provisions.

               (2)  Rank. The Series A Preferred Stock shall rank junior to the
Series B Convertible Participating Preferred Stock ("Series B Preferred Stock")
and the Series C Convertible Redeemable Preferred Stock (the "Series C Preferred
Stock") with respect to dividend rights and rights on liquidation, dissolution
or winding up as set forth in Article IV(A), paragraph (3) and Article IV(A),
paragraph (4), and prior to all classes of Common Stock with respect to rights
on liquidation, dissolution or winding up. All equity securities of the
Corporation to which the Series A Preferred Stock ranks prior (whether with
respect to dividends or upon liquidation, dissolution, winding up or otherwise),
including the Common Stock, are collectively referred to in this Article IV(A)
as the "JUNIOR SECURITIES." All equity securities of the Corporation with which
the Series A Preferred Stock ranks on a parity (whether with respect to
dividends or upon liquidation, dissolution or winding up) are collectively
referred to in this Article IV(A) as the "PARITY SECURITIES." The respective
definitions of Junior Securities and Parity Securities shall also include any
rights or options exercisable for or convertible into any of the Junior
Securities and Parity Securities, as the case may be.

               (3)  Dividends. Shares of Series A Preferred Stock shall rank
junior as to dividend rights to shares of Series B Preferred Stock and Series C
Preferred Stock. Each share of Series A Preferred Stock shall be entitled to
receive, when, as and if declared by the Board of Directors, out of funds
legally available for the payment of dividends, dividends to the same extent as,
on the same basis as, at the same rate as, and contemporaneously with, dividends
when, as and if declared by the Board of Directors with respect to shares of
Common Stock or Parity Securities. Such dividends shall be payable on the dates
specified by the Board of Directors as the dates for payment of dividends in
respect of shares of Common Stock or Parity Securities (each of such dates being
a "DIVIDEND PAYMENT DATE") (unless such day is not a business day, in which
event on the next succeeding business day), in preference to dividends on the
Junior Securities. Such dividends shall be paid to the holders of record at the
close of business on the date specified by the Board of Directors of the
Corporation at the time such dividend is declared, provided that such date shall
not be more than 60 days nor less than 10 days prior to the respective dividend
payment date. If the Corporation shall at any time after the date of issuance of
the Series A Preferred Stock pay any dividend on Common Stock payable in shares
of Common Stock or effect a subdivision or combination of the outstanding shares
of Common Stock (by reclassification or otherwise) into a greater or lesser
number of shares of Common Stock, then in each such case the dividend amount to
which holders of shares of Series A Preferred Stock were entitled immediately
prior to such event under the preceding sentence shall be adjusted by
multiplying such amount by a fraction of which the numerator is the number of
shares of Common Stock outstanding immediately after such event and of which the


                                       2
   3

denominator is the number of shares of Common Stock that were outstanding
immediately prior to such event.

        (4)    Liquidation Preference.

        (a)    In the event of any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, before any payment or
distribution of the assets of the Corporation (whether capital or surplus) shall
be made to or set apart for the holders of Junior Securities, but after payment
in full to holders of Series B Preferred Stock and Series C Preferred Stock of
all amounts due thereunder, the holders of the shares of Series A Preferred
Stock shall be entitled to receive an amount in cash equal to $1.091 per share
of Series A Preferred Stock, plus an amount equal to all dividends declared and
unpaid thereon to the date of final distribution to such holders. If, upon any
liquidation, dissolution or winding up of the Corporation, the assets of the
Corporation, or proceeds thereof, distributable among the holders of the shares
of Series A Preferred Stock, after payment in full to holders of Series B
Preferred Stock and Series C Preferred Stock of all amounts due thereunder,
shall be insufficient to pay in full the preferential amount aforesaid and
liquidating payments on any Parity Securities, then such assets, or the proceeds
thereof, shall be distributed among the holders of shares of Series A Preferred
Stock and any such other Parity Securities ratably in accordance with the
respective amounts that would be payable on such shares of Series A Preferred
Stock and any such other Parity Securities if all amounts payable thereon were
paid in full. Subject to the rights of the holders of any Parity Securities,
after payment shall have been made in full to the holders of the Series A
Preferred Stock, as provided in this Article IV(A), paragraph (4), any other
series or class or classes of Junior Securities shall, subject to the respective
terms and provisions (if any) applying thereto, be entitled to receive any and
all assets remaining to be paid or distributed, and the holders of the Series A
Preferred Stock shall not be entitled to share therein.

        (b)    For the purposes of this Article IV(A), paragraph (4), (i) a
consolidation or merger of the Corporation with one or more corporations, or
(ii) a sale or transfer of all or substantially all of the Corporation's assets,
shall be deemed to be a liquidation, dissolution or winding up, voluntary or
involuntary, of the Corporation.

        (5)    Conversion.

        (a)    Subject to the provisions of this Article IV(A), paragraph (5), 
each holder of the shares of Series A Preferred Stock shall have the right, at
any time and from time to time, at such holder's option, to convert any or all
outstanding shares (and fractional shares) of Series A Preferred Stock, in whole
or in part, into fully paid and non-assessable shares of Common Stock.

        (b)    Subject to the provisions of this Article IV(A), paragraph (5), 
all of the outstanding shares (and fractional shares) of Series A Preferred
Stock shall be converted automatically into fully paid and non-assessable shares
of Common Stock upon the occurrence of a Series A Trigger Event. Any conversion
pursuant to this Article IV(A), paragraph 5(b) shall occur automatically,
without further action on the part of the holders or the Corporation.

        (c) The number of shares of Common Stock deliverable upon conversion of
a share of Series A Preferred Stock, adjusted as hereinafter provided, is
referred to in this Article 


                                       3
   4

IV(A) as the "SERIES A CONVERSION RATIO." The Series A Conversion Ratio as of
August 3, 1998 is one, subject to adjustment from time to time pursuant to
Article IV(A), paragraph (5)(g) hereof.

        (d)(i) In order to exercise the conversion privilege and upon the
occurrence of a Series A Trigger Event, the holder of the shares of Series A
Preferred Stock to be converted shall surrender the certificate representing
such shares at the office of the Corporation, with, in the case of any
conversion pursuant to Article IV(A), paragraph 5(a), a written notice of
election to convert completed and signed, specifying the number of shares to be
converted. Unless the shares issuable on conversion are to be issued in the same
name as the name in which such shares of Series A Preferred Stock are
registered, each share surrendered for conversion shall, subject to the
provisions of the Securityholders Agreement, be accompanied by instruments of
transfer, in form satisfactory to the Corporation, duly executed by the holder
or the holder's duly authorized attorney and an amount sufficient to pay any
transfer or similar tax.

        (ii)   As promptly as practicable after the surrender by the holder of 
the certificates for shares of Series A Preferred Stock as aforesaid, the
Corporation shall issue and shall deliver to such holder, or on the holder's
written order to the holder's transferee, a certificate or certificates for the
whole number of shares of Common Stock issuable upon the conversion of such
shares in accordance with the provisions of this Article IV(A), paragraph (5).

        (iii)  Each conversion shall be deemed to have been effected (x) in the
case of any conversion pursuant to Article IV(A), paragraph 5(a), immediately
prior to the close of business on the date on which the certificates for shares
of Series A Preferred Stock shall have been surrendered and such notice received
by the Corporation as aforesaid or (y) in the case of any conversion pursuant to
Article IV(A), paragraph 5(b), on the date of the Series A Trigger Event, and
the person in whose name or names any certificate or certificates for shares of
Common Stock shall be issuable upon such conversion shall be deemed to have
become the holder of record of the shares of Common Stock represented thereby at
such time on such date and such conversion shall be into a number of shares of
Common Stock equal to the product of the number of shares of Series A Preferred
Stock surrendered times the Series A Conversion Ratio in effect at such time on
such date. All shares of Common Stock delivered upon conversion of the Series A
Preferred Stock will upon delivery be duly and validly issued and fully paid and
non-assessable, free of all liens and charges and not subject to any preemptive
rights. Upon the surrender of certificates representing shares of Series A
Preferred Stock, such shares shall no longer be deemed to be outstanding and all
rights of a holder with respect to such shares surrendered for conversion shall
immediately terminate except the right to receive the Common Stock and any other
amounts payable pursuant to this Article IV(A), paragraph (5).

        (e)(i) From the date of delivery by a holder of shares of Series A
Preferred Stock of such holder's shares of Series A Preferred Stock (and, in the
case of any conversion pursuant to Article IV(A), paragraph 5(b), upon the
occurrence of a Series A Trigger Event), such Series A Preferred Stock shall
continue to participate equally and ratably with the holders of shares of Common
Stock in all dividends paid on the Common Stock as if such shares of Series A
Preferred Stock had been converted to shares of Common Stock at the time of such
delivery or Series A Trigger Event.


                                       4
   5

        (ii)   Except to the extent provided above in Article IV(A), paragraph
(5)(e)(i) and in Article IV(A), paragraph (5)(g), the Corporation shall make no
payment or adjustment for accrued and unpaid dividends on the shares of Series A
Preferred Stock, whether or not in arrears, on conversion of such shares or for
dividends in cash on the shares of Common Stock issued upon such conversion.

        (f)(i) The Corporation covenants that it will at all times reserve and
keep available, free from preemptive rights, such number of its authorized but
unissued shares of Common Stock as shall be required for the purpose of
effecting conversions of the Series A Preferred Stock.

        (ii)   Prior to the delivery of any securities which the Corporation 
shall be obligated to deliver upon conversion of the Series A Preferred Stock,
the Corporation shall comply with respect to the issuance of such securities
with all applicable federal and state laws and regulations which require action
to be taken by the Corporation.

        (iii)  The Corporation will pay any and all documentary stamp or similar
issue or transfer taxes payable in respect of the issue or delivery of shares of
Common Stock on conversion of the Series A Preferred Stock pursuant hereto;
provided that the Corporation shall not be required to pay any tax which may be
payable in respect of any transfer involving the issue or delivery of shares of
Common Stock in a name other than that of the holder of the Series A Preferred
Stock to be converted and no such issue or delivery shall be made unless and
until the person requesting such issue or delivery has paid to the Corporation
the amount of any such tax or has established, to the satisfaction of the
Corporation, that such tax has been paid.

        (iv)   In connection with the conversion of any shares of Series A
Preferred Stock, no fractions of shares of Common Stock shall be issued, but in
lieu thereof the Corporation shall pay a cash adjustment in respect of such
fractional interest in an amount equal to such fractional interest multiplied by
the Daily Price per share of Common Stock on the business day on which such
shares of Series A Preferred Stock are deemed to have been converted.

        (g)(i) In case the Corporation shall at any time after August 3, 1998
(I) declare a dividend or make a distribution on Common Stock payable in Common
Stock (other than a dividend in which shares of Series A Preferred Stock
participate as provided in Article IV(A), paragraph (3)), (II) subdivide or
split the outstanding Common Stock, (III) combine or reclassify the outstanding
Common Stock into a smaller number of shares, (IV) issue any shares of its
capital stock in a reclassification of Common Stock (including any such
reclassification in connection with a consolidation or merger in which the
Corporation is the continuing Corporation, other than any such consolidation or
merger which results in the payment to the holders of Series A Preferred Stock
of the liquidation preference as provided in Article IV(A), paragraph (4)), or
(V) consolidate with, or merge with or into, any other Person (other than any
such consolidation or merger which results in the payment to the holders of
Series A Preferred Stock of the liquidation preference as provided in Article
IV(A), paragraph (4)), the Series A Conversion Ratio in effect at the time of
the record date for such dividend or distribution or of the effective date of
such subdivision, split, combination, consolidation, merger or reclassification
shall be proportionately adjusted so that the conversion of the Series A
Preferred Stock after such time shall entitle the holder to receive the
aggregate number of shares of 


                                       5
   6

Common Stock or other securities of the Corporation (or shares of any security
into which such shares of Common Stock have been combined, consolidated, merged
or reclassified pursuant to clause (III), (IV) or (V) above) which, if this
Series A Preferred Stock had been converted immediately prior to such time, such
holder would have owned upon such conversion and been entitled to receive by
virtue of such dividend, distribution, subdivision, split, combination,
consolidation, merger or reclassification, assuming such holder of Common Stock
of the Corporation (x) is not a Person with which the Corporation consolidated
or into which the Corporation merged or which merged into the Corporation or to
which such recapitalization, sale or transfer was made, as the case may be
("CONSTITUENT PERSON"), or an affiliate of a constituent person and (y) failed
to exercise any rights of election as to the kind or amount of securities, cash
and other property receivable upon such reclassification, change, consolidation,
merger, recapitalization, sale or transfer (provided, that if the kind or amount
of securities, cash and other property receivable upon such reclassification,
change, consolidation, merger, recapitalization, sale or transfer is not the
same for each share of Common Stock of the Corporation held immediately prior to
such reclassification, change, consolidation, merger, recapitalization, sale or
transfer by other than a constituent person or an affiliate thereof and in
respect of which such rights of election shall not have been exercised
("NON-ELECTING SHARE"), then for the purpose of this Article IV(A), paragraph
(5)(g) the kind and amount of securities, cash and other property receivable
upon such reclassification, change, consolidation, merger, recapitalization,
sale or transfer by each non-electing share shall be deemed to be the kind and
amount so receivable per share by a plurality of the non-electing shares). Such
adjustments shall be made successively whenever any event listed above shall
occur.

        (ii)   In case the Corporation shall at any time after August 3, 1998
issue or sell any Common Stock (other than Common Stock issued (I) upon
conversion of the Series A Preferred Stock, the Series B Preferred Stock, the
Series C Preferred Stock or the Notes, (II) pursuant to the Corporation's stock
option plans or pursuant to any other Common Stock related employee compensation
plan of the Corporation approved by the Corporation's Board of Directors, (III)
upon exercise or conversion of any security the setting of a record date for
which or issuance of which caused an adjustment under Article IV(A), paragraphs
(5)(g)(iii) or (g)(iv) hereof, (IV) upon exercise of warrants issued to lenders
of the Corporation including, without limitation, pursuant to the Bridge
Securities Purchase Agreement, (V) in connection with any bona fide, arms-length
direct or indirect merger, acquisition or similar transaction) without
consideration or for a consideration per share less than the then Conversion
Price Per Common Share, the Series A Conversion Ratio to be in effect after such
issuance or sale shall be determined by multiplying the Series A Conversion
Ratio in effect immediately prior to such issuance or sale by a fraction, (A)
the numerator of which shall be the sum of (x) the product of the aggregate
number of shares of Common Stock outstanding immediately after such issuance or
sale and the Current Valuation Per Common Share immediately prior to such
issuance or sale plus (y) the aggregate of the product of each share of Fully
Diluted Common Stock (other than shares of Common Stock included in (A)(x) or
employee stock options) outstanding immediately prior to such issuance or sale
and the Exercise Price applicable to such share of Fully Diluted Common Stock
and (B) the denominator of which shall be the sum of (x) the number of shares of
Common Stock outstanding immediately prior to the time of such issuance or sale
multiplied by the Current Valuation Per Common Share immediately prior to such
issuance or sale, plus (y) the aggregate of the product of each share of Fully
Diluted Common Stock (other than shares of Common Stock included in (B)(x) or
employee stock options) outstanding immediately prior to such issuance or sale
and the Exercise Price applicable to such share of Fully Diluted Common 


                                       6
   7

Stock, plus (z) the aggregate consideration, if any, to be received by the
Corporation upon such issuance or sale. In case any portion of the consideration
to be received by the Corporation shall be in a form other than cash, the fair
market value of such noncash consideration shall be utilized in the foregoing
computation. Such fair market value shall be determined by the Board of
Directors of the Corporation; provided that if the holders of 25% of the Series
A Preferred Stock shall object to any such determination, the Board of Directors
shall retain an independent appraiser reasonably satisfactory to such holders to
determine such fair market value. The holders shall be notified promptly of any
consideration other than cash to be received by the Corporation and furnished
with a description of the consideration and the fair market value thereof, as
determined by the Board of Directors.

        (iii)  In case the Corporation shall at any time after August 3, 1998 
fix a record date for the issuance of rights, options or warrants to the holders
of its Common Stock or other securities of the Corporation entitling such
holders to subscribe for or purchase shares of Common Stock (or securities
convertible into shares of Common Stock), with respect to which the holders of
Series A Preferred Stock do not participate pursuant to Article IV(A), paragraph
(3), at a price per share of Common Stock (or having a conversion price per
share of Common Stock, if a security convertible into shares of Common Stock)
less than the then Conversion Price Per Common Share on such record date, the
maximum number of shares of Common Stock issuable upon exercise of such rights,
options or warrants (or conversion of such convertible securities) shall be
deemed to have been issued and outstanding as of such record date and the Series
A Conversion Ratio shall be adjusted pursuant to Article IV(A), paragraph
(5)(g)(ii) hereof, as though such maximum number of shares of Common Stock had
been so issued for the aggregate consideration payable by the holders of such
rights, options, warrants or convertible securities prior to their receipt of
such shares of Common Stock. In case any portion of such consideration shall be
in a form other than cash, the fair market value of such noncash consideration
shall be determined as set forth in Article IV(A), paragraph (5)(g)(ii) hereof.
Such adjustment shall be made successively whenever such record date is fixed;
and in the event that such rights, options or warrants are not so issued or
expire unexercised, or in the event of a change in the number of shares of
Common Stock to which the holders of such rights, options or warrants are
entitled (other than pursuant to adjustment provisions therein comparable to
those contained in this Article IV(A), paragraph (5)(g)), the Series A
Conversion Ratio shall again be adjusted to be the Series A Conversion Ratio
which would then be in effect if such record date had not been fixed, in the
former event, or the Series A Conversion Ratio which would then be in effect if
such holder had initially been entitled to such changed number of shares of
Common Stock, in the latter event.

        (iv)   In case the Corporation shall at any time after August 3, 1998
issue rights, options (other than options issued pursuant to a plan described in
clause II of Article IV(A), paragraph (5)(g)(ii)) or warrants (other than
warrants described in clause IV of Article IV(A), paragraph (5)(g)(ii))
entitling the holders thereof to subscribe for or purchase Common Stock (or
securities convertible into shares of Common Stock) or shall issue convertible
securities, and the price per share of Common Stock of such rights, options,
warrants or convertible securities (including, in the case of rights, options or
warrants, the price at which they may be exercised) is less than the then
Conversion Price Per Common Share, the maximum number of shares of Common Stock
issuable upon exercise of such rights, options or warrants or upon conversion of
such convertible securities shall be deemed to have been issued and outstanding
as of the date of such sale or issuance, and the Series A Conversion Ratio shall
be adjusted pursuant to Article 


                                       7
   8

IV(A), paragraph (5)(g)(ii) hereof as though such maximum number of shares of
Common Stock had been so issued for an aggregate consideration equal to the
aggregate consideration paid for such rights, options, warrants or convertible
securities and the aggregate consideration payable by the holders of such
rights, options, warrants or convertible securities prior to their receipt of
such shares of Common Stock. In case any portion of such consideration shall be
in a form other than cash, the fair market value of such noncash consideration
shall be determined as set forth in Article IV(A), paragraph (5)(g)(ii) hereof.
Such adjustment shall be made successively whenever such rights, options,
warrants or convertible securities are issued; and in the event that such
rights, options or warrants expire unexercised, or in the event of a change in
the number of shares of Common Stock to which the holders of such rights,
options, warrants or convertible securities are entitled (other than pursuant to
adjustment provisions therein comparable to those contained in this Article
IV(A), paragraph (5)(g)), the Series A Conversion Ratio shall again be adjusted
to be the Series A Conversion Ratio which would then be in effect if such
rights, options, warrants or convertible securities had not been issued, in the
former event, or the Series A Conversion Ratio which would then be in effect if
such holders had initially been entitled to such changed number of shares of
Common Stock, in the latter event. No adjustment of the Series A Conversion
Ratio shall be made pursuant to this Article IV(A), paragraph (5)(g)(iv) to the
extent that the Series A Conversion Ratio shall have been adjusted pursuant to
Article IV(A), paragraph (5)(g)(iii) (or is not required to be adjusted pursuant
to Article IV(A), paragraph (5)(g)(iii) because holders of the Series A
Preferred Stock have participated pursuant to Article IV(A), paragraph (3)) upon
the setting of any record date relating to such rights, options, warrants or
convertible securities and such adjustment fully reflects the number of shares
of Common Stock to which the holders of such rights, options, warrants or
convertible securities are entitled and the price payable therefor.

        (v)    In case the Corporation shall at any time after August 3, 1998 
fix a record date for the making of a distribution to holders of Common Stock
(including any such distribution made in connection with a consolidation or
merger in which the Corporation is the continuing corporation, other than any
such consolidation or merger which results in the payment to holders of Series A
Preferred Stock of the liquidation preference as provided in Article IV(A),
paragraph (4)) of evidences of indebtedness, assets or other property (other
than dividends payable in Common Stock or rights, options or warrants referred
to in, and for which an adjustment is made pursuant to Article IV(A), paragraph
(5)(g)(iii) hereof) with respect to which the holders of the Series A Preferred
Stock do not participate pursuant to Article IV(A), paragraph (3), the Series A
Conversion Ratio to be in effect after such record date shall be determined by
multiplying the Series A Conversion Ratio in effect immediately prior to such
record date by a fraction, (A) the numerator of which shall be the Current
Valuation Per Common Share on such record date, and (B) the denominator of which
shall be the Current Valuation Per Common Share on such record date, less the
fair market value (determined as set forth in Article IV(A), paragraph
(5)(g)(ii) hereof) of the portion of the assets, other property or evidence of
indebtedness so to be distributed which is applicable to one share of Common
stock. Such adjustments shall be made successively whenever such a record date
is fixed; and in the event that such distribution is not so made, the Series A
Conversion Ratio shall again be adjusted to be the Series A Conversion Ratio
which would then be in effect if such record date had not been fixed.


                                       8
   9

        (vi)   For purposes of any computation under this Article IV(A), 
paragraph (5)(f)(iv) or paragraph (5)(g), the number of shares of Common Stock
outstanding at any given time shall not include shares owned or held by or for
the account of the Corporation.

        (vii)  No adjustment to the Series A Conversion Ratio pursuant to 
Article IV(A), paragraphs (5)(g)(ii), (iii), (iv) and (v) above shall be
required unless such adjustment would require an increase or decrease of at
least 1% in the Series A Conversion Ratio; provided however, that any
adjustments which by reason of this Article IV(A), paragraph (5)(g)(vii) are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations under this Article IV(A), paragraph
(5)(g) shall be made to the nearest four decimal points.

        (viii) In the event that, at any time as a result of the provisions of
this Article IV(A), paragraph (5)(g), the holders of the Series A Preferred
Stock upon subsequent conversion shall become entitled to receive any shares of
capital stock of the Corporation other than Common Stock, the number of such
other shares so receivable upon conversion of the Series A Preferred Stock shall
thereafter be subject to adjustment from time to time in a manner and on terms
as nearly equivalent as practicable to the provisions contained herein.

        (ix) In the event:

        (A) of any capital reorganization or reclassification of the Common
        Stock (other than a subdivision or combination of the outstanding Common
        Stock and other than a change in par value of the Common Stock) or of
        any consolidation or merger to which the Corporation is a party and for
        which approval of any stockholders of the Corporation is required (other
        than a consolidation or merger in which the Corporation is the
        continuing corporation and that does not result in any reclassification
        or change of the Common Stock outstanding), or of the conveyance or
        transfer of the properties and assets of the Corporation substantially
        as an entirety; or

        (B) of the voluntary or involuntary dissolution, liquidation or
        winding-up of the Corporation; or

        (C) the Corporation proposes to take any action (other than actions of
        the character described in Article IV(A), paragraph (5)(g)(i)(I) or
        (II)) that would require an adjustment pursuant to this Article IV(A),
        paragraph (5)(g) to the number of shares purchasable upon conversion;

then the Corporation shall cause to be mailed by first-class mail to the holders
of Series A Preferred Stock, at least five days prior to the applicable record
or effective date hereinafter specified (10 days in the case of the events
referred to in clauses (A) and (B) above), a notice stating (x) the date as of
which the holders of Common Stock of record to be entitled to receive any such
rights, warrants or distributions are to be determined, or (y) the date on which
any such consolidation, merger, conveyance, transfer, dissolution, liquidation
or winding-up is expected to become effective, and the date as of which it is
expected that holders of Common Stock of record shall be entitled to exchange
their shares of Common Stock for securities or other property, if 


                                       9
   10

any, deliverable upon such reorganization, reclassification, consolidation,
merger, conveyance, transfer, dissolution, liquidation or winding-up.

        (h)    All adjustments pursuant to this Article IV(A), paragraph (5) 
shall be notified to the holders of this Series A Preferred Stock and such
notice shall be accompanied by a schedule of computation of the adjustments.

        (6)    Voting Rights.

        (a)    Except as otherwise provided by applicable law, the holders of 
the shares of Series A Preferred Stock (i) shall be entitled to vote with the
holders of the Common Stock on all matters submitted for a vote of holders of
Common Stock, (ii) shall be entitled to a number of votes equal to the number of
votes to which shares of Common Stock issuable upon conversion of such shares of
Series A Preferred Stock would have been entitled if such shares of Common Stock
had been outstanding at the time of the applicable vote and related record date
and (iii) shall be entitled to notice of any stockholders' meeting in accordance
with the Amended and Restated Certificate of Incorporation and Bylaws of the
Corporation. Except as otherwise provided by applicable law and as set forth in
Article IV(A), paragraph (6)(b) below, the shares of Series A Preferred Stock
shall vote together with the shares of Common Stock as a single class.

        (b)    Without the written consent or affirmative vote at a meeting 
called for that purpose of the holders of a majority of the shares of Series A
Preferred Stock then outstanding, the Corporation shall not take any of the
following actions:

        (i)    create, authorize, or issue any class or series of stock other 
        than the Series B Preferred Stock ranking prior to the Series A
        Preferred Stock (whether with respect to dividends or upon liquidation,
        dissolution or winding up) or any Parity Securities, or increase the
        authorized number of shares of any such class or series, or reclassify
        any authorized stock of the Corporation into any such prior shares or
        Parity Securities, or create, authorize or issue any obligation or
        security convertible into or evidencing the right to purchase any such
        prior shares or Parity Securities;

        (ii)   issue more shares of the Series A Preferred Stock;

        (iii)  voluntarily liquidate, dissolve, or wind up the Corporation un
        less provision for the payment of the liquidation preference is made in
        accordance with Article IV(A), paragraph (4) or

        (iv)   amend, alter, or repeal, whether by merger, consolidation or
        otherwise, any of the provisions of the Amended and Restated Certificate
        of Incorporation or Bylaws of the Corporation in a manner adverse to the
        preferences, privileges, voting rights or powers of the Series A
        Preferred Stock.

        (c)    Except as otherwise required by applicable law or as set forth
herein, the shares of Series A Preferred Stock shall not have any relative,
participating, optional or other special voting rights and powers and the
consent of the holders thereof shall not be required for the taking of any
corporate action.


                                       10
   11

        (7)    General Provision. Shares of Series A Preferred Stock which have
been issued and reacquired in any manner, including shares purchased or
redeemed, shall (upon compliance with any applicable state laws) have the status
of authorized and unissued shares of the class of Preferred Stock undesignated
as to series and may be redesignated and reissued as part of any series of the
Preferred Stock; provided that no such issued and reacquired shares of Series A
Preferred Stock shall be reissued or sold as Series A Preferred Stock.

        (8)    Prohibition of Payments Pending Redemption of the Series C 
Preferred Stock. Notwithstanding anything to the contrary contained in this
Article IV(A), no payments of any kind (including but not limited to any
dividend payments) payable on the Series A Preferred Stock shall be made unless
and until at least 95% of the shares of Series C Preferred Stock issued pursuant
to the Series C Preferred Stock Securities Purchase Agreement entered into by
the Corporation on or about August 3, 1998 (the "Series C Purchase Agreement")
shall have first been redeemed in accordance with Article IV(C), paragraph (5)
or converted, except that after August 3, 2000, the Corporation shall be
permitted to pay dividends on the Series A Preferred Stock, when and if declared
by the Board of Directors, for any dividend period after that date, but only to
the extent that (i) the payments relate to the current Dividend Period and
provide no payments for dividends accruing prior to the dividend payment date
and (ii) full cumulative dividends on all outstanding shares of Series C
Preferred Stock shall have first been paid for the current and all dividend
periods prior to such payment. The limitation on payments set forth in this
Article IV(A), paragraph (8) shall terminate upon (a) a consolidation or merger
of the Corporation with one or more corporations, or (b) a sale or transfer of
all or substantially all of the Corporation's stock or assets; provided that, in
the event of (a) or (b), the Series C Preferred Stock has received its full
liquidation preference in accordance with Article IV(C), paragraph (4).

        (B)    Series B Preferred Stock

        The following is a statement of the designations, powers, privileges,
preferences and relative, participating, optional or other special rights, and
the qualifications, limitations or restrictions relating to the Series B
Preferred Stock:

        (1)    Number and Designation. 3,857,280 shares of the Preferred Stock 
of the Corporation shall be designated as Series B Convertible Participating
Preferred Stock. Each share of Series B Preferred Stock shall rank equally in
all respects and shall be subject to the following provisions.

        (2)    Rank. The Series B Preferred Stock shall rank junior to the
Series C Preferred Stock with respect to dividend rights, redemption rights and
rights on liquidation, dissolution or winding up as set forth in Article IV(B)
paragraph (3) and Article IV(B), paragraph (4). The Series B Preferred Stock
shall, with respect to dividend rights and rights on liquidation, dissolution or
winding up, rank prior to the Corporation's Series A Preferred Stock and all
classes of the Corporation's Common Stock, in each case, as set forth in Article
IV(B), paragraph (3) and Article IV(B), paragraph (4). All equity securities of
the Corporation to which the Series B Preferred Stock ranks prior (whether with
respect to dividends or upon liquidation, dissolution, winding up or otherwise),
including the Common Stock, are collectively referred to in this Article IV(B)
as the "JUNIOR SECURITIES." All equity securities of the Corporation with which
the Series B Preferred Stock ranks on a parity (whether with respect to
dividends or upon 


                                       11
   12
liquidation, dissolution or winding up) are collectively referred to in this
Article IV(B) as the "PARITY SECURITIES." The respective definitions of Junior
Securities and Parity Securities in this Article IV(B) shall also include any
rights or options exercisable for or convertible into any of the Junior
Securities and Parity Securities, as the case may be. The Series B Preferred
Stock shall be subject to the creation of Junior Securities and Parity
Securities.

        (3)    Dividends.

        (a)    Subject to the rights of the holders of shares of Series C 
Preferred Stock, the holders of shares of Series B Preferred Stock shall be
entitled to receive, when, as and if declared by the Board of Directors, out of
funds legally available for the payment of dividends, cash dividends at (i) a
rate of 25% per annum of the Original Liquidation Amount (as defined below) per
share for the period from the date of issuance of such shares until November 23,
1997 (the "Decrease Date"), and (ii) the Applicable Rate (as defined below) in
effect in respect of each Dividend Period (as defined below) thereafter.
Notwithstanding the foregoing, if for any Dividend Period the holder of such
amount of Common Stock as a holder of Series B Preferred Stock would be entitled
to receive upon conversion would be entitled to receive any dividend and such
dividend would, but for the provisions of this Article IV(B) paragraph (3),
exceed the dividend payable on one share of Series B Preferred Stock in respect
of such period, the dividend payable per share of Series B Preferred Stock in
respect of such period shall be increased so as to equal the dividend payable on
a share of Common Stock in respect of such period. Such dividends shall be
payable in arrears in equal amounts quarterly on March 31, June 30, Sept. 30 and
Dec. 31 of each year (unless such day is not a business day, in which event on
the next succeeding business day) (each of such dates being a "DIVIDEND PAYMENT
DATE" and each such quarterly period (or portion thereof) being a "DIVIDEND
PERIOD"). Such dividends shall be cumulative from the date of issue, whether or
not in any Dividend Period or Periods there shall be funds of the Corporation
legally available for the payment of such dividends. Such dividends shall be
paid to the holders of record at the close of business on the date specified by
the Board of Directors of the Corporation at the time such dividend is declared,
provided that such date shall not be more than 60 days nor less than 10 days
prior to the respective Dividend payment Date. Accrued and unpaid dividends for
any past Dividend Periods may be declared and paid at any time, without
reference to any Dividend Payment Date, to holders of record on such date, not
more than 45 days preceding the payment date thereof, as may be fixed by the
Board of Directors. As used herein, (x) "Applicable Rate" in effect in respect
of any Dividend Period after the Decrease Date shall mean the rate per annum
equal to the greater of (A) 12.5% of the Original Liquidation Amount per share
and (B) the Original Liquidation Amount per share multiplied by the sum of the
Prime Rate in effect on the first business day of such Dividend Period plus 2%,
and (y) "Prime Rate" means the rate of interest publicly announced by Citibank,
N.A. in The City of New York from time to time as its prime rate.

        (b)    Except in the case where the amount of dividends payable is
determined pursuant to the second sentence of Article IV(B), paragraph 3(a), the
amount of dividends payable for each full Dividend Period for the Series B
Preferred Stock shall be computed by dividing the annual dividend rate by four,
and the amount of dividends payable for the initial Dividend Period, or any
other period shorter or longer than a full Dividend Period, on the Series B
Preferred Stock shall be computed on the basis of twelve 30-day months and a
360-day year. Holders of shares of Series B Preferred Stock shall not be
entitled to any dividends, whether payable in cash, property or stock, in excess
of cumulative dividends, as herein provided, on the 


                                       12
   13

Series B Preferred Stock. No interest, or sum of money in lieu of interest,
shall be payable in respect of any dividend payment or payments on the Series B
Preferred Stock that may be in arrears.

        (c)    So long as any shares of the Series B Preferred Stock are
outstanding, no dividends, except as described in the next succeeding sentence,
shall be declared or paid or set apart for payment on Parity Securities, for any
period unless full cumulative dividends have been or contemporaneously are
declared and paid or declared and a sum sufficient for the payment thereof set
apart for such payment on the Series B Preferred Stock for all Dividend Periods
terminating on or prior to the date of payment of the dividend on such class or
series of Parity Securities. When dividends are not paid in full or a sum
sufficient for such payment is not set apart, as aforesaid, all dividends
declared upon shares of the Series B Preferred Stock and all dividends declared
upon any other class or series of Parity Securities shall be declared ratably in
proportion to the respective amounts of dividends accumulated and unpaid on the
Series B Preferred Stock and accumulated and unpaid on such Parity Securities.

        (d)    So long as any shares of the Series B Preferred Stock are
outstanding, no dividends (other than dividends or distributions paid in shares
of, or options, warrants or rights to subscribe for or purchase shares of,
Junior Securities) shall be declared or paid or set apart for payment or other
distribution declared or made upon Junior Securities, nor shall any Junior
Securities be redeemed, purchased or otherwise acquired (other than a
redemption, purchase or other acquisition of shares of Common Stock made
pursuant to an employee incentive or benefit plan of the Corporation or any
subsidiary) (all such dividends, distributions, redemptions or purchases being
hereinafter referred to as a "JUNIOR SECURITIES DISTRIBUTION") for any
consideration (or any moneys be paid to or made available for a sinking fund for
the redemption of any shares of any such stock) by the Corporation, directly or
indirectly (except by conversion into or exchange for Junior Securities), unless
in each case (i) the full cumulative dividends on all outstanding shares of the
Series B Preferred Stock and any other Parity Securities shall have been paid or
set apart for payment for all past Dividend Periods with respect to the Series B
Preferred Stock and all past dividend periods with respect to such Parity
Securities and (ii) sufficient funds shall have been paid or set apart for the
payment of the dividend for the current Dividend Period with respect to the
Series B Preferred Stock and the current dividend period with respect to such
Parity Securities.

        (4)    Liquidation Preference.

        (a)    Subject to the rights of the holders of shares of Series C 
Preferred Stock, in the event of any liquidation, dissolution or winding up of
the Corporation, whether voluntary or involuntary, before any payment or
distribution of the assets of the Corporation (whether capital or surplus) shall
be made to or set apart for the holders of Junior Securities, the holders of the
shares of Series B Preferred Stock shall be entitled to receive the greater of
(x) $1.5555 per share of Series B Preferred Stock (the "Original Liquidation
Amount") plus an amount equal to all dividends (whether or not earned or
declared) accrued and unpaid thereon to the date of final distribution to such
holders and (y) the amount that would have been received by a holder of one
share of Series B Preferred Stock had it converted such share as provided in
Article IV(B), paragraph (7) immediately prior to such liquidation, dissolution
or winding-up (and assuming similar conversion by all holders of Series B
Preferred Stock). If, upon any liquidation, dissolution or winding up of the
Corporation, the assets of the Corporation, or proceeds thereof, 


                                       13
   14

distributable among the holders of the shares of Series B Preferred Stock shall
be insufficient to pay in full the preferential amount aforesaid and liquidating
payments on any Parity Securities, then such assets, or the proceeds thereof,
shall be distributed among the holders of shares of Series B Preferred Stock and
any such other Parity Securities ratably in accordance with the respective
amounts that would be payable on such shares of Series B Preferred Stock and any
such other stock if all amounts payable thereon were paid in full. For the
purposes of this Article IV(B), paragraph (4), (i) a consolidation or merger of
the Corporation with one or more corporations, or (ii) a sale or transfer of all
or substantially all of the Corporation's assets, shall be deemed to be a
liquidation, dissolution or winding up, voluntary or involuntary, of the
Corporation.

        (b)    Subject to the rights of the holders of any Parity Securities, 
after payment shall have been made in full to the holders of the Series B
Preferred Stock, as provided in this Article IV(B), paragraph (4), any other
series or class or classes of Junior Securities shall, subject to the respective
terms and provisions (if any) applying thereto, be entitled to receive any and
all assets remaining to be paid or distributed, and the holders of the Series B
Preferred Stock shall not be entitled to share therein.

        (5)    Redemption.

        (a)    Subject to the rights of the holders of Series C Preferred Stock,
to the extent the Corporation shall have funds legally available for such
payment, on July 15, 2005, if any shares of the Series B Preferred Stock shall
be outstanding, the Corporation shall redeem all then outstanding shares of the
Series B Preferred Stock, at a redemption price of $1.5555 per share in cash,
together with accrued and unpaid dividends thereon to such date, without
interest.

        (b)    Shares of Series B Preferred Stock which have been issued and
reacquired in any manner, including shares purchased or redeemed, shall (upon
compliance with any applicable provisions of applicable state laws) have the
status of authorized and unissued shares of the class of Preferred Stock
undesignated as to series and may be redesignated and reissued as part of any
series of the Preferred Stock; provided that no such issued and reacquired
shares of Series B Preferred Stock shall be reissued or sold as Series B
Preferred Stock.

        (c)    Subject to the rights of the holders of the Series C Preferred
Stock, if the Corporation is unable or shall fail to discharge its obligation to
redeem all outstanding shares of Series B Preferred Stock pursuant to Article
IV(B), paragraph (5)(a) (the "MANDATORY REDEMPTION OBLIGATION"), the Mandatory
Redemption Obligation shall be discharged as soon as the Corporation is able to
discharge such Mandatory Redemption Obligation. If and so long as any Mandatory
Redemption Obligation with respect to the Series B Preferred Stock shall not be
fully discharged, the Corporation shall not (i) directly or indirectly, redeem,
purchase, or otherwise acquire any Parity Security or discharge any mandatory or
optional redemption, sinking fund or other similar obligation in respect of any
Parity Securities (except in connection with a redemption, sinking fund or other
similar obligation to be satisfied pro rata with the Series B Preferred Stock)
or (ii) in accordance with Article IV(B), paragraph (3)(d), declare or make any
Junior Securities Distribution, or, directly or indirectly, discharge any
mandatory or optional redemption, sinking fund or other similar obligation in
respect of the Junior Securities.


                                       14
   15

        (d)    Notwithstanding the foregoing provisions of this Article IV(B),
paragraph (5), unless full cumulative cash dividends (whether or not declared)
on all outstanding shares of Series B Preferred Stock shall have been paid or
contemporaneously are declared and paid or set apart for payment for all
Dividend Periods terminating on or prior to the applicable redemption date, none
of the shares of Series B Preferred Stock shall be redeemed, and no sum shall be
set aside for such redemption, unless shares of Series B Preferred Stock are
redeemed (in accordance with the provisions of this Article IV(B), paragraph (5)
and for the redemption price plus accrued and unpaid dividends) pro rata among
the holders thereof.

        (6)    Procedure for Redemption.

        (a)    In the event that fewer than all the outstanding shares of Series
B Preferred Stock are to be redeemed, the number of shares to be redeemed shall
be determined by the Board of Directors and the shares to be redeemed shall be
selected by lot or pro rata (with any fractional shares being rounded to the
nearest whole share) as may be determined by the Board of Directors (subject to
Article IV(B), paragraph (5)(f)).

        (b)    In the event the Corporation shall redeem shares of Series B
Preferred Stock, notice of such redemption shall be given by first class mail,
postage prepaid, mailed not less than 30 days nor more than 60 days prior to the
redemption date, to each holder of record of the shares to be redeemed at such
holder's address as the same appears on the stock register of the Corporation;
provided that neither the failure to give such notice nor any defect therein
shall affect the validity of the giving of notice for the redemption of any
share of Series B Preferred Stock to be redeemed except as to the holder to whom
the Corporation has failed to give said notice or except as to the holder whose
notice was defective. Each such notice shall state: (i) the redemption date;
(ii) the number of shares of Series B Preferred Stock to be redeemed and, if
fewer than all the shares held by such holder are to be redeemed, the number of
shares to be redeemed from such holder; (iii) the redemption price; (iv) the
place or places where certificates for such shares are to be surrendered for
payment of the redemption price; and (v) that dividends on the shares to be
redeemed will cease to accrue on such redemption date.

        (c)    Notice having been mailed as aforesaid, from and after the
redemption date (unless default shall be made by the Corporation in providing
money for the payment of the redemption price of the shares called for
redemption), dividends on the shares of Series B Preferred Stock so called for
redemption shall cease to accrue, and all rights of the holders thereof as
stockholders of the Corporation (except the right to receive from the
Corporation the redemption price, together with accrued and unpaid dividends
thereon to the date fixed for redemption, without interest) shall cease. Upon
surrender in accordance with said notice of the certificates for any shares so
redeemed (properly endorsed or assigned for transfer, if the Board of Directors
of the Corporation shall so require and the notice shall so state), such share
shall be redeemed by the Corporation at the redemption price aforesaid. In case
fewer than all the shares represented by any such certificate are redeemed, a
new certificate shall be issued representing the unredeemed shares without cost
to the holder thereof.

        (7)    Conversion.

        (a)    Subject to the provisions of this Article IV(B), paragraph (7), 
each holder of the shares of Series B Preferred Stock shall have the right, at
any time and from time to time, 


                                       15
   16

at such holder's option, to convert any or all outstanding shares (and
fractional shares) of Series B Preferred Stock, in whole or in part, into fully
paid and non-assessable shares of Common Stock.

        (ii)   Subject to the provisions of this Article IV(B), paragraph (7), 
all of the outstanding shares (and fractional shares) of Series B Preferred
Stock shall be converted automatically into fully paid and non-assessable shares
of Common Stock upon the occurrence of a Series B Trigger Event. Any conversion
pursuant to this Article IV(B), paragraph 7(a)(ii) shall occur automatically,
without further action on the part of the holders or the Corporation.

        (iii) The number of shares of Common Stock deliverable upon conversion
of a share of Series B Preferred Stock, adjusted as hereinafter provided, is
referred to in this Article IV(B) as the "SERIES B CONVERSION RATIO." The Series
B Conversion Ratio as of August 3, 1998 is one, subject to adjustment from time
to time pursuant to Article IV(B), paragraph (7)(h) hereof. Notwithstanding any
call for redemption pursuant to Article IV(B), paragraph (5), the right to
convert shares so called for redemption shall terminate at the close of business
on the date immediately preceding the date fixed for such redemption unless the
Corporation shall default in making payment of the amount payable upon such
redemption.

        (b)    [Purposely left blank].

        (c)(i) In order to exercise the conversion privilege and upon the
occurrence of a Series B Trigger Event, the holder of the shares of Series B
Preferred Stock to be converted shall surrender the certificate representing
such shares at the office of the Corporation, with, in the case of any
conversion pursuant to Article IV(B), paragraph (7)(a)(i), a written notice of
election to convert completed and signed, specifying the number of shares to be
converted. Unless the shares issuable on conversion are to be issued in the same
name as the name in which such shares of Series B Preferred Stock are
registered, each share surrendered for conversion shall, subject to the
provisions of the Securityholders Agreement, be accompanied by instruments of
transfer, in form satisfactory to the Corporation, duly executed by the holder
or the holder's duly authorized attorney and an amount sufficient to pay any
transfer or similar tax.

        (ii)   As promptly as practicable after the surrender by the holder of 
the certificates for shares of Series B Preferred Stock as aforesaid, the
Corporation shall issue and shall deliver to such holder, or on the holder's
written order to the holder's transferee, a certificate or certificates for the
whole number of shares of Common Stock issuable upon the conversion of such
shares in accordance with the provisions of this Article IV(B), paragraph (7).

        (iii) Each conversion shall be deemed to have been effected (x) in the
case of any conversion pursuant to Article IV(B), paragraph 7(a)(i), immediately
prior to the close of business on the date on which the certificates for shares
of Series B Preferred Stock shall have been surrendered and such notice received
by the Corporation as aforesaid or (y) in the case of any conversion pursuant to
Article IV(B), paragraph 7(a)(ii), on the date of the Series B Trigger Event,
and the person in whose name or names any certificate or certificates for shares
of Common Stock shall be issuable upon such conversion shall be deemed to have
become the holder of record of the shares of Common Stock represented thereby at
such time on such date and such conversion shall be into a number of shares of
Common Stock equal to the product of the number of shares of Series B Preferred
Stock surrendered times the Series B Conversion 


                                       16
   17

Ratio in effect at such time on such date. All shares of Common Stock delivered
upon conversion of the Series B Preferred Stock will upon delivery be duly and
validly issued and fully paid and non-assessable, free of all liens and charges
and not subject to any preemptive rights. Upon the surrender of certificates
representing shares of Series B Preferred Stock, such shares shall no longer be
deemed to be outstanding and all rights of a holder with respect to such shares
surrendered for conversion shall immediately terminate except the right to
receive the Common Stock and other amounts payable pursuant to this Article
IV(B), paragraph (7).

        (d)(i) Upon delivery to the Corporation by a holder of shares of Series
B Preferred Stock of a notice of election to convert, the right of the
Corporation to redeem such shares of Series B Preferred Stock shall terminate,
regardless of whether a notice of redemption has been mailed as aforesaid.

        (ii)   From the date of delivery by a holder of shares of Series B
Preferred Stock of such holder's shares of Series B Preferred Stock (and in the
case of any conversion pursuant to Article IV(B), paragraph 7(a)(ii), upon the
occurrence of a Series B Trigger Event), in lieu of dividends on such Series B
Preferred Stock pursuant to Article IV(B), paragraph (3), such Series B
Preferred Stock shall participate equally and ratably with the holders of shares
of Common Stock in all dividends paid on the Common Stock as if such shares of
Series B Preferred Stock had been converted to shares of Common Stock at the
time of such delivery or Series B Trigger Event.

        (iii)  Except to the extent provided above in Article IV(B), paragraph
(7)(d)(ii) and in Article IV(B), paragraph (7)(h), the Corporation shall make no
payment or adjustment for accrued and unpaid dividends on the shares of Series B
Preferred Stock, whether or not in arrears, on conversion of such shares or for
dividends in cash on the shares of Common Stock issued upon such conversion.

        (e)(i) The Corporation covenants that it will at all times reserve and
keep available, free from preemptive rights, such number of its authorized but
unissued shares of Common Stock as shall be required for the purpose of
effecting conversions of the Series B Preferred Stock.

        (ii)   Prior to the delivery of any securities which the Corporation 
shall be obligated to deliver upon conversion of the Series B Preferred Stock,
the Corporation shall comply with respect to the issuance of such securities
with all applicable federal and state laws and regulations which require action
to be taken by the Corporation.

        (f)    The Corporation will pay any and all documentary stamp or similar
issue or transfer taxes payable in respect of the issue or delivery of shares of
Common Stock on conversion of the Series B Preferred Stock pursuant hereto;
provided that the Corporation shall not be required to pay any tax which may be
payable in respect of any transfer involving the issue or delivery of shares of
Common Stock in a name other than that of the holder of the Series B Preferred
Stock to be converted and no such issue or delivery shall be made unless and
until the person requesting such issue or delivery has paid to the Corporation
the amount of any such tax or has established, to the satisfaction of the
Corporation, that such tax has been paid.


                                       17
   18

        (g)    In connection with the conversion of any shares of Series B
Preferred Stock, no fractions of shares of Common Stock shall be issued, but in
lieu thereof the Corporation shall pay a cash adjustment in respect of such
fractional interest in an amount equal to such fractional interest multiplied by
the Daily Price per share of Common Stock on the business day on which such
shares of Series B Preferred Stock are deemed to have been converted.

        (h)(i) In case the Corporation shall at any time after August 3, 1998
(I) declare a dividend or make a distribution on Common Stock payable in Common
Stock, (II) subdivide or split the outstanding Common Stock, (III) combine or
reclassify the outstanding Common Stock into a smaller number of shares, (IV)
issue any shares of its capital stock in a reclassification of Common Stock
(including any such reclassification in connection with a consolidation or
merger in which the Corporation is the continuing corporation, other than any
such consolidation or merger which results in the payment to the holders of
Series B Preferred Stock of the liquidation preference as provided in Article
IV(B), paragraph (4)), or (V) consolidate with, or merge with or into, any other
Person (other than any such consolidation or merger which results in the payment
to the holders of Series B Preferred Stock of the liquidation preference as
provided in Article IV(B), paragraph (4)), the Series B Conversion Ratio in
effect at the time of the record date for such dividend or distribution or of
the effective date of such subdivision, split, combination, consolidation,
merger or reclassification shall be proportionately adjusted so that the
conversion of the Series B Preferred Stock after such time shall entitle the
holder to receive the aggregate number of shares of Common Stock or other
securities of the Corporation (or shares of any security into which such shares
of Common Stock have been combined, consolidated, merged or reclassified
pursuant to clause (III), (IV) or (V) above) which, if this Series B Preferred
Stock had been converted immediately prior to such time, such holder would have
owned upon such conversion and been entitled to receive by virtue of such
dividend, distribution, subdivision, split, combination, consolidation, merger
or reclassification, assuming such holder of Common Stock of the Corporation (x)
is not a constituent person, or an affiliate of a constituent person and (y)
failed to exercise any rights of election as to the kind or amount of
securities, cash and other property receivable upon such reclassification,
change, consolidation, merger, recapitalization, sale or transfer (provided,
that if the kind or amount of securities, cash and other property receivable
upon such reclassification, change, consolidation, merger, recapitalization,
sale or transfer is not the same for each non-electing share of Common Stock of
the Corporation held immediately prior to such reclassification, change,
consolidation, merger, recapitalization, sale or transfer by other than a
constituent person or an affiliate thereof, then for the purpose of this Article
IV(B), subparagraph (h) the kind and amount of securities, cash and other
property receivable upon such reclassification, change, consolidation, merger,
recapitalization, sale or transfer by each non-electing share shall be deemed to
be the kind and amount so receivable per share by a plurality of the
non-electing shares). Such adjustment shall be made successively whenever any
event listed above shall occur.

        (ii)   In case the Corporation shall at any time after August 3, 1998
issue or sell any Common Stock (other than Common Stock issued (I) upon
conversion of the Series A Preferred Stock, the Series B Preferred Stock, the
Series C Preferred Stock or the Notes, (II) pursuant to the Corporation's stock
option plans or pursuant to any other Common Stock related employee compensation
plan of the Corporation approved by the Corporation's Board of Directors, (III)
upon exercise or conversion of any security the setting of a record date for
which or issuance of which caused an adjustment under Article IV(B), paragraphs
(7)(h)(iii) or (h)(iv) 


                                       18

hereof, (IV) upon exercise of warrants issued to lenders of the Corporation
including, without limitation, pursuant to the Bridge Securities Purchase
Agreement or (V) in connection with any bona fide, arms-length direct or
indirect merger, acquisition or similar transaction) without consideration or
for a consideration per share less than the then Conversion Price Per Common
Share, the Series B Conversion Ratio to be in effect after such issuance or sale
shall be determined by multiplying the Series B Conversion Ratio in effect
immediately prior to such issuance or sale by a fraction, (A) the numerator of
which shall be the sum of (x) the product of the aggregate number of shares of
Common Stock outstanding immediately after such issuance or sale and the Current
Valuation Per Common Share immediately prior to such issuance or sale plus (y)
the aggregate of the product of each share of Fully Diluted Common Stock (other
than shares of Common Stock included in (A)(x) or employee stock options)
outstanding immediately prior to such issuance or sale and the Exercise Price
applicable to such share of Fully Diluted Common Stock and (B) the denominator
of which shall be the sum of (x) the number of shares of Common Stock
outstanding immediately prior to the time of such issuance or sale multiplied by
the Current Valuation Per Common Share immediately prior to such issuance or
sale, plus (y) the aggregate of the product of each share of Fully Diluted
Common Stock (other than shares of Common Stock included in (B)(x) or employee
stock options) outstanding immediately prior to such issuance or sale and the
Exercise Price applicable to such share of Fully Diluted Common Stock, plus (z)
the aggregate consideration, if any, to be received by the Corporation upon such
issuance or sale. In case any portion of the consideration to be received by the
Corporation shall be in a form other than cash, the fair market value of such
noncash consideration shall be utilized in the foregoing computation. Such fair
market value shall be determined by the Board of Directors of the Corporation;
provided that if the holders of 25% of the Series B Preferred Stock shall object
to any such determination, the Board of Directors shall retain an independent
appraiser reasonably satisfactory to such holders to determine such fair market
value. The holders shall be notified promptly of any consideration other than
cash to be received by the Corporation and furnished with a description of the
consideration and the fair market value thereof, as determined by the Board of
Directors.

        (iii) In case the Corporation shall at any time after August 3, 1998 fix
a record date for the issuance of rights, options or warrants to the holders of
its Common Stock or other securities of the Corporation entitling such holders
to subscribe for or purchase shares of Common Stock (or securities convertible
into shares of Common Stock) at a price per share of Common Stock (or having a
conversion price per share of Common Stock, if a security convertible into
shares of Common Stock) less than the then Conversion Price Per Common Share on
such record date, the maximum number of shares of Common Stock issuable upon
exercise of such rights, options or warrants (or conversion of such convertible
securities) shall be deemed to have been issued and outstanding as of such
record date and the Series B Conversion Ratio shall be adjusted pursuant to
Article IV(B), paragraph (7)(h)(ii) hereof, as though such maximum number of
shares of Common Stock had been so issued for the aggregate consideration
payable by the holders of such rights, options, warrants or convertible
securities prior to their receipt of such shares of Common Stock. In case any
portion of such consideration shall be in a form other than cash, the fair
market value of such noncash consideration shall be determined as set forth in
Article IV(B), paragraph (7)(h)(ii) hereof. Such adjustment shall be made
successively whenever such record date is fixed; and in the event that such
rights, options or warrants are not so issued or expire unexercised, or in the
event of a change in the number of shares of Common Stock to which the holders
of such rights, options or warrants are entitled (other than pursuant to
adjustment provisions therein comparable to those contained in this 


                                       19
   20

Article IV(B), paragraph (7)(h)), the Series B Conversion Ratio shall again be
adjusted to be the Series B Conversion Ratio which would then be in effect if
such record date had not been fixed, in the former event, or the Series B
Conversion Ratio which would then be in effect if such holder had initially been
entitled to such changed number of shares of Common Stock, in the latter event.

        (iv)   In case the Corporation shall at any time after August 3, 1998
issue rights, options (other than options issued pursuant to a plan described in
clause II of Article IV(B), paragraph (h)(ii)) or warrants (other than warrants
described in clause IV of Article IV(B), paragraph (h) (ii)) entitling the
holders thereof to subscribe for or purchase Common Stock (or securities
convertible into shares of Common Stock) or shall issue convertible securities,
and the price per share of Common Stock of such rights, options, warrants or
convertible securities (including, in the case of rights, options or warrants,
the price at which they may be exercised) is less than the then Conversion Price
Per Common Share, the maximum number of shares of Common Stock issuable upon
exercise of such rights, options or warrants or upon conversion of such
convertible securities shall be deemed to have been issued and outstanding as of
the date of such sale or issuance, and the Series B Conversion Ratio shall be
adjusted pursuant to Article IV(B), paragraph (7)(h)(ii) hereof as though such
maximum number of shares of Common Stock had been so issued for an aggregate
consideration equal to the aggregate consideration paid for such rights,
options, warrants or convertible securities and the aggregate consideration
payable by the holders of such rights, options, warrants or convertible
securities prior to their receipt of such shares of Common Stock. In case any
portion of such consideration shall be in a form other than cash, the fair
market value of such noncash consideration shall be determined as set forth in
Article IV(B), paragraph (7)(h)(ii) hereof. Such adjustment shall be made
successively whenever such rights, options, warrants or convertible securities
are issued; and in the event that such rights, options or warrants expire
unexercised, or in the event of a change in the number of shares of Common Stock
to which the holders of such rights, options, warrants or convertible securities
are entitled (other than pursuant to adjustment provisions therein comparable to
those contained in this Article IV(B), paragraph (7)(h)), the Series B
Conversion Ratio shall again be adjusted to be the Series B Conversion Ratio
which would then be in effect if such rights, options, warrants or convertible
securities had not been issued, in the former event, or the Series B Conversion
Ratio which would then be in effect if such holders had initially been entitled
to such changed number of shares of Common Stock, in the latter event. No
adjustment of the Series B Conversion Ratio shall be made pursuant to this
Article IV(B), paragraph (7)(h)(iv) to the extent that the Series B Conversion
Ratio shall have been adjusted pursuant to Article IV(B), paragraph (7)(h)(iii)
upon the setting of any record date relating to such rights, options, warrants
or convertible securities and such adjustment fully reflects the number of
shares of Common Stock to which the holders of such rights, options, warrants or
convertible securities are entitled and the price payable therefor.

        (v)    In case the Corporation shall at any time after August 3, 1998 
fix a record date for the making of a distribution to holders of Common Stock
(including any such distribution made in connection with a consolidation or
merger in which the Corporation is the continuing corporation, other than any
such consolidation or merger which results in the payment to holders of Series B
Preferred Stock of the liquidation preference as provided in Article IV(B),
paragraph (4)) of evidences of indebtedness, assets or other property (other
than dividends payable in Common Stock or rights, options or warrants referred
to in, and for which an adjustment is made pursuant to Article IV(B), paragraph
(7)(h)(iii) hereof), the Series B 


                                       20
   21

Conversion Ratio to be in effect after such record date shall be determined by
multiplying the Series B Conversion Ratio in effect immediately prior to such
record date by a fraction, (A) the numerator of which shall be the Current
Valuation Per Common Share on such record date, and (B) the denominator of which
shall be the Current Valuation Per Common Share on such record date, less the
fair market value (determined as set forth in Article IV(B), paragraph
(7)(h)(ii) hereof) of the portion of the assets, other property or evidence of
indebtedness so to be distributed which is applicable to one share of Common
Stock. Such adjustments shall be made successively whenever such a record date
is fixed; and in the event that such distribution is not so made, the Series B
Conversion Ratio shall again be adjusted to be the Series B Conversion Ratio
which would then be in effect if such record date had not been fixed.

        (vi)   For purposes of any computation under Article IV(B), paragraph
(7)(g) or paragraph (7)(h), the number of shares of Common Stock outstanding at
any given time shall not include shares owned or held by or for the account of
the Corporation.

        (vii)  No adjustment to the Series B Conversion Ratio pursuant to 
Article IV(B), paragraphs (7)(h)(ii), (iii), (iv) and (v) above shall be
required unless such adjustment would require an increase or decrease of at
least 1% in the Series B Conversion Ratio; provided however, that any
adjustments which by reason of this Article IV(B), paragraph (7)(h)(vii) are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations under this Article IV(B), paragraph
(7)(h) shall be made to the nearest four decimal points.

        (viii) In the event that, at any time as a result of the provisions of
this Article IV(B), paragraph (7)(h), the holders of the Series B Preferred
Stock upon subsequent conversion shall become entitled to receive any shares of
capital stock of the Corporation other than Common Stock, the number of such
other shares so receivable upon conversion of the Series B Preferred Stock shall
thereafter be subject to adjustment from time to time in a manner and on terms
as nearly equivalent as practicable to the provisions contained herein.

        (ix) In the event:

        (A) of any capital reorganization or reclassification of the Common
        Stock (other than a subdivision or combination of the outstanding Common
        Stock and other than a change in par value of the Common Stock) or of
        any consolidation or merger to which the Corporation is a party and for
        which approval of any stockholders of the Corporation is required (other
        than a consolidation or merger in which the Corporation is the
        continuing corporation and that does not result in any reclassification
        or change of the Common Stock outstanding), or of the conveyance or
        transfer of the properties and assets of the Corporation substantially
        as an entirety; or

        (B) of the voluntary or involuntary dissolution, liquidation or
        winding-up of the Corporation; or

        (C) the Corporation proposes to take any action (other than actions of
        the character described in Article IV(B), paragraph (7)(h)(i)(I) or
        (II)) that would 


                                       21

   22
               require an adjustment pursuant to this Article IV(B), paragraph
               (7)(h) to the number of shares purchasable upon conversion;

then the Corporation shall cause to be mailed by first-class mail to the holders
of Series B Preferred Stock, at least five days prior to the applicable record
or effective date hereinafter specified (10 days in the case of the events
referred to in clauses (A) and (B) above), a notice stating (x) the date as of
which the holders of Common Stock of record to be entitled to receive any such
rights, warrants or distributions are to be determined, or (y) the date on which
any such consolidation, merger, conveyance, transfer, dissolution, liquidation
or winding-up is expected to become effective, and the date as of which it is
expected that holders of Common Stock of record shall be entitled to exchange
their shares of Common Stock for securities or other property, if any,
deliverable upon such reorganization, reclassification, consolidation, merger,
conveyance, transfer, dissolution, liquidation or winding-up.

               (i)  All adjustments pursuant to this Article IV(B), paragraph 
(7) shall be notified to the holders of this Series B Preferred Stock and such
notice shall be accompanied by a schedule of computation of the adjustments.

               (8)  Voting Rights.

               (a)  Except as otherwise provided by applicable law, the holders
of the shares of Series B Preferred Stock (i) shall be entitled to vote with the
holders of the Common Stock on all matters submitted for a vote of holders of
Common Stock, (ii) shall be entitled to a number of votes equal to the number of
votes to which shares of Common Stock issuable upon conversion of such shares of
Series B Preferred Stock would have been entitled if such shares of Common Stock
had been outstanding at the time of the applicable vote and related record date
and (iii) shall be entitled to notice of any stockholders' meeting in accordance
with the Amended and Restated Certificate of Incorporation and Bylaws of the
Corporation. Except as otherwise provided by applicable law and as set forth in
Article IV(D) below, the shares of Series B Preferred Stock shall vote together
with the shares of Common Stock as a single class.

               (b)  Except as otherwise required by applicable law or as set
forth herein, the shares of Series B Preferred Stock shall not have any
relative, participating, optional or other special voting rights and powers and
the consent of the holders thereof shall not be required for the taking of any
corporate action.

               (9)  Reports. So long as any of the Series B Preferred Stock is
outstanding, the Corporation will furnish the holders thereof with the quarterly
and audited annual financial reports that the Corporation is required to file
with the Securities and Exchange Commission pursuant to Section 13 or Section
15(d) of the Securities Exchange Act of 1934 or, in the event the Corporation is
not required to file such reports, reports containing substantially the same
information as would be required in such reports (it being understood that the
foregoing shall not be construed to require presentation in the manner required
by such Act and the regulations thereunder so long as the data required
thereunder is so provided).

               (10) Prohibition of Payments Pending Redemption of the Series C
Preferred Stock. Notwithstanding anything to the contrary contained in this
Article IV(A), no payments of any kind (including but not limited to any
redemption or dividend payments) payable on the 


                                       22
   23

Series B Preferred Stock shall be made unless and until at lest 95% of the
shares of Series C Preferred Stock issued pursuant to the Series C Purchase
Agreement shall have first been redeemed in accordance with Article IV(C),
paragraph (5) or converted, except that after August 3, 2000, the Corporation
shall be permitted to pay dividends on the Series B Preferred Stock, when and if
declared by the Board of Directors, for any Dividend Period after that date, but
only to the extent that (i) the payments relate to the current Dividend Period
and provide no payments for dividends accruing prior to the Dividend Payment
Date and (ii) full cumulative dividends on all outstanding shares of Series C
Preferred Stock shall have first been paid for the current and all Dividend
Periods prior to such payments. The limitation on payments set forth in this
Article IV(B), paragraph (10) shall terminate upon (a) a consolidation or merger
of the Corporation with one or more corporations, or (b) a sale or transfer of
all or substantially all of the Corporation's stock or assets; provided that, in
the event of (a) or (b), the Series C Preferred Stock has received its full
liquidation preference in accordance with Article IV(C), paragraph (4).

               (C)  Series C Preferred Stock.

               The following is a statement of the designations, powers,
privileges, preferences and relative, participating, optional or other special
rights, and the qualifications, limitations or restrictions relating to the
Series C Preferred Stock:

               (1)  Number and Designation. 7,500,000 shares of the Preferred
Stock of the Corporation shall be designated as Series C Convertible Redeemable
Preferred Stock. Each share of Series C Preferred Stock shall rank equally in
all respects and shall be subject to the following provisions.

               (2)  Rank. The Series C Preferred Stock shall, with respect to
dividend rights, redemption rights and rights on liquidation, dissolution or
winding up, rank prior to the Corporation's Series A Preferred Stock, Series B
Preferred Stock and all classes of the Corporation's Common Stock, in each case,
as set forth in Article IV(C), paragraph (3) and Article IV(C), paragraph (4).
All equity securities of the Corporation to which the Series C Preferred Stock
ranks prior (whether with respect to dividends or upon liquidation, dissolution,
winding up or otherwise), including the Common Stock, are collectively referred
to in this Article IV(C) as the "JUNIOR SECURITIES." All equity securities of
the Corporation with which the Series C Preferred Stock ranks on a parity
(whether with respect to dividends or upon liquidation, dissolution or winding
up) are collectively referred to in this Article IV(C) as the "PARITY
SECURITIES." The respective definitions of Junior Securities and Parity
Securities in this Article IV(C) shall also include any rights or options
exercisable for or convertible into any of the Junior Securities and Parity
Securities, as the case may be. The Series C Preferred Stock shall be subject to
the creation of Junior Securities and Parity Securities.

               (3)  Dividends.

               (a)  After the second anniversary of the date of issuance of the
Series C Preferred Stock, the holders of shares of Series C Preferred Stock
shall be entitled to receive, when, as and if declared by the Board of
Directors, out of funds legally available for the payment of dividends, cash
dividends at the Applicable Rate (as defined below) in effect in respect of each
Dividend Period (as defined below). Notwithstanding the foregoing, if for any
Dividend Period the holder of such amount of Common Stock as a holder of Series
C Preferred Stock


                                       23
   24

would be entitled to receive upon conversion would be entitled to receive any
dividend and such dividend would, but for the provisions of this Article IV(C)
paragraph (3), exceed the dividend payable on one share of Series C Preferred
Stock in respect of such period, the dividend payable per share of Series C
Preferred Stock in respect of such period shall be increased so as to equal the
dividend payable on a share of Common Stock in respect of such period. Such
dividends shall be payable in arrears in equal amounts quarterly on March 31,
June 30, Sept. 30 and Dec. 31 of each year (unless such day is not a business
day, in which event on the next succeeding business day) (each of such dates
being a "DIVIDEND PAYMENT DATE" and each such quarterly period (or portion
thereof) being a "DIVIDEND PERIOD"). Such dividends shall be cumulative from the
date of issue, whether or not in any Dividend Period or Periods there shall be
funds of the Corporation legally available for the payment of such dividends.
Such dividends shall be paid to the holders of record at the close of business
on the date specified by the Board of Directors of the Corporation at the time
such dividend is declared, provided that such date shall not be more than 60
days nor less than 10 days prior to the respective Dividend Payment Date.
Accrued and unpaid dividends for any past Dividend Periods may be declared and
paid at any time, without reference to any Dividend Payment Date, to holders of
record on such date, not more than 45 days preceding the payment date thereof,
as may be fixed by the Board of Directors. As used herein, (x) "Applicable Rate"
in effect in respect of any Dividend Period after the second anniversary of the
date of issuance of the Series C Preferred Stock shall mean the rate per annum
equal to the greater of (A) $0.50 per share and (B) $4.00 per share multiplied
by the sum of the Prime Rate in effect on the first business day of such
Dividend Period plus 2%, and (y) "Prime Rate" means the rate of interest
publicly announced by Citibank, N.A. in The City of New York from time to time
as its prime rate.

               (b)  Except in the case where the amount of dividends payable is
determined pursuant to the second sentence of Article IV(C), paragraph 3(a), the
amount of dividends payable for each full Dividend Period for the Series C
Preferred Stock shall be computed by dividing the annual dividend rate by four,
and the amount of dividends payable for the initial Dividend Period, or any
other period shorter or longer than a full Dividend Period, on the Series C
Preferred Stock shall be computed on the basis of twelve 30-day months and a
360-day year. Holders of shares of Series C Preferred Stock shall not be
entitled to any dividends, whether payable in cash, property or stock, in excess
of cumulative dividends, as herein provided, on the Series C Preferred Stock. No
interest, or sum of money in lieu of interest, shall be payable in respect of
any dividend payment or payments on the Series C Preferred Stock that may be in
arrears.

               (c)  So long as any shares of the Series C Preferred Stock are
outstanding, no dividends, except as described in the next succeeding sentence,
shall be declared or paid or set apart for payment on Parity Securities, for any
period unless full cumulative dividends have been or contemporaneously are
declared and paid or declared and a sum sufficient for the payment thereof set
apart for such payment on the Series C Preferred Stock for all Dividend Periods
terminating on or prior to the date of payment of the dividend on such class or
series of Parity Securities. When dividends are not paid in full or a sum
sufficient for such payment is not set apart, as aforesaid, all dividends
declared upon shares of the Series C Preferred Stock and all dividends declared
upon any other class or series of Parity Securities shall be declared ratably in
proportion to the respective amounts of dividends accumulated and unpaid on the
Series C Preferred Stock and accumulated and unpaid on such Parity Securities.


                                       24
   25

               (d)  So long as any shares of the Series C Preferred Stock are
outstanding, no dividends (other than dividends or distributions paid in shares
of, or options, warrants or rights to subscribe for or purchase shares of,
Junior Securities) shall be declared or paid or set apart for payment or other
distribution declared or made upon Junior Securities, nor shall any Junior
Securities be redeemed, purchased or otherwise acquired (other than a
redemption, purchase or other acquisition of shares of Common Stock made
pursuant to an employee incentive or benefit plan of the Corporation or any
subsidiary) (all such dividends, distributions, redemptions or purchases being
hereinafter referred to as a "JUNIOR SECURITIES DISTRIBUTION") for any
consideration (or any moneys be paid to or made available for a sinking fund for
the redemption of any shares of any such stock) by the Corporation, directly or
indirectly (except by conversion into or exchange for Junior Securities).

               (4)  Liquidation Preference. In the event of any liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
before any payment or distribution of the assets of the Corporation (whether
capital or surplus) shall be made to or set apart for the holders of Junior
Securities, the holders of the shares of Series C Preferred Stock shall be
entitled to receive the greater of (x) $5.00 per share of Series C Preferred
Stock (the "Original Liquidation Amount") plus an amount equal to all dividends
(whether or not earned or declared) accrued and unpaid thereon to the date of
final distribution to such holders and (y) the amount that would have been
received by a holder of one share of Series C Preferred Stock had it converted
such share as provided in Article IV(C), paragraph (7) immediately prior to such
liquidation, dissolution or winding-up (and assuming similar conversion by all
holders of Series C Preferred Stock). If, upon any liquidation, dissolution or
winding up of the Corporation, the assets of the Corporation, or proceeds
thereof, distributable among the holders of the shares of Series C Preferred
Stock shall be insufficient to pay in full the preferential amount aforesaid and
liquidating payments on any Parity Securities, then such assets, or the proceeds
thereof, shall be distributed among the holders of shares of Series C Preferred
Stock and any such other Parity Securities ratably in accordance with the
respective amounts that would be payable on such shares of Series C Preferred
Stock and any such other stock if all amounts payable thereon were paid in full.
For the purposes of this Article IV(C), paragraph (4), (i) a consolidation or
merger of the Corporation with one or more corporations, or (ii) a sale or
transfer of all or substantially all of the Corporation's assets, shall be
deemed to be a liquidation, dissolution or winding up, voluntary or involuntary,
of the Corporation; provided, however, that in the case of a transaction of the
type described in either clause (i) or (ii), no amount of accrued and unpaid
dividends shall be payable as part of a liquidation preference payment pursuant
to this Article (IV)(C), paragraph (4) if 100% of the consideration paid to the
Corporation or the stockholders of the Corporation consist of securities of the
acquiring entity.

               (b)  Subject to the rights of the holders of any Parity
Securities, after payment shall have been made in full to the holders of the
Series C Preferred Stock, as provided in this Article IV(C), paragraph (4), any
other series or class or classes of Junior Securities shall, subject to the
respective terms and provisions (if any) applying thereto, be entitled to
receive any and all assets remaining to be paid or distributed, and the holders
of the Series C Preferred Stock shall not be entitled to share therein.


                                       25
   26

               (5)  Redemption.

               (a)  To the extent the Corporation shall have funds legally
available for such payment, on July 15, 2005, if any shares of the Series C
Preferred Stock shall be outstanding, the Corporation shall redeem all then
outstanding shares of the Series C Preferred Stock, at a redemption price of
$5.00 per share in cash, together with accrued and unpaid dividends thereon to
such date, without interest.

               (b)  Shares of Series C Preferred Stock which have been issued 
and reacquired in any manner, including shares purchased or redeemed, shall
(upon compliance with any applicable provisions of applicable state laws) have
the status of authorized and unissued shares of the class of Preferred Stock
undesignated as to series and may be redesignated and reissued as part of any
series of the Preferred Stock; provided that no such issued and reacquired
shares of Series C Preferred Stock shall be reissued or sold as Series C
Preferred Stock.

               (c)  If the Corporation is unable or shall fail to discharge its
obligation to redeem all outstanding shares of Series C Preferred Stock pursuant
to Article IV(C), paragraph (5)(a) (the "MANDATORY REDEMPTION OBLIGATION"), the
Mandatory Redemption Obligation shall be discharged as soon as the Corporation
is able to discharge such Mandatory Redemption Obligation. If and so long as any
Mandatory Redemption Obligation with respect to the Series C Preferred Stock
shall not be fully discharged, the Corporation shall not (i) directly or
indirectly, redeem, purchase, or otherwise acquire any Parity Security or
discharge any mandatory or optional redemption, sinking fund or other similar
obligation in respect of any Parity Securities (except in connection with a
redemption, sinking fund or other similar obligation to be satisfied pro rata
with the Series C Preferred Stock) or (ii) in accordance with Article IV(C),
paragraph (3)(d), declare or make any Junior Securities Distribution, or,
directly or indirectly, discharge any mandatory or optional redemption, sinking
fund or other similar obligation in respect of the Junior Securities.

               (d)  Notwithstanding the foregoing provisions of this Article
IV(C), paragraph (5), unless full cumulative cash dividends (whether or not
declared) on all outstanding shares of Series C Preferred Stock shall have been
paid or contemporaneously are declared and paid or set apart for payment for all
Dividend Periods terminating on or prior to the applicable redemption date, none
of the shares of Series C Preferred Stock shall be redeemed, and no sum shall be
set aside for such redemption, unless shares of Series C Preferred Stock are
redeemed (in accordance with the provisions of this Article IV(C), paragraph (5)
and for the redemption price plus accrued and unpaid dividends) pro rata among
the holders thereof.

               (6)  Procedure for Redemption.

               (a)  In the event that fewer than all the outstanding shares of
        Series C Preferred Stock are to be redeemed, the number of shares to be
        redeemed shall be determined by the Board of Directors and the shares to
        be redeemed shall be pro rata (with any fractional shares being rounded
        to the nearest whole share) (subject to Article IV(C), paragraph
        (5)(d)).

               (b)  In the event the Corporation shall redeem shares of Series C
Preferred Stock, notice of such redemption shall be given by first class mail,
postage prepaid, mailed not 


                                       26
   27

less than 30 days nor more than 60 days prior to the redemption date, to each
holder of record of the shares to be redeemed at such holder's address as the
same appears on the stock register of the Corporation; provided that neither the
failure to give such notice nor any defect therein shall affect the validity of
the giving of notice for the redemption of any share of Series C Preferred Stock
to be redeemed except as to the holder to whom the Corporation has failed to
give said notice or except as to the holder whose notice was defective. Each
such notice shall state: (i) the redemption date; (ii) the number of shares of
Series C Preferred Stock to be redeemed and, if fewer than all the shares held
by such holder are to be redeemed, the number of shares to be redeemed from such
holder; (iii) the redemption price; (iv) the place or places where certificates
for such shares are to be surrendered for payment of the redemption price; and
(v) that dividends on the shares to be redeemed will cease to accrue on such
redemption date.

               (c)  Notice having been mailed as aforesaid, from and after the
redemption date (unless default shall be made by the Corporation in providing
money for the payment of the redemption price of the shares called for
redemption), dividends on the shares of Series C Preferred Stock so called for
redemption shall cease to accrue, and all rights of the holders thereof as
stockholders of the Corporation (except the right to receive from the
Corporation the redemption price, together with accrued and unpaid dividends
thereon to the date fixed for redemption, without interest) shall cease. Upon
surrender in accordance with said notice of the certificates for any shares so
redeemed (properly endorsed or assigned for transfer, if the Board of Directors
of the Corporation shall so require and the notice shall so state), such share
shall be redeemed by the Corporation at the redemption price aforesaid. In case
fewer than all the shares represented by any such certificate are redeemed, a
new certificate shall be issued representing the unredeemed shares without cost
to the holder thereof.

               (7)  Conversion.

               (a)  Subject to the provisions of this Article IV(C), paragraph
(7), each holder of the shares of Series C Preferred Stock shall have the right,
at any time and from time to time, at such holder's option, to convert any or
all outstanding shares (and fractional shares) of Series C Preferred Stock, in
whole or in part, into fully paid and non-assessable shares of Common Stock.

               (ii) Subject to the provisions of this Article IV(C), paragraph
(7), all of the outstanding shares (and fractional shares) of Series C Preferred
Stock shall be converted automatically into fully paid and non-assessable shares
of Common Stock upon the occurrence of a Series C Trigger Event. Any conversion
pursuant to this Article IV(C), paragraph 7(a)(ii) shall occur automatically,
without further action on the part of the holders or the Corporation.

               (iii) The number of shares of Common Stock deliverable upon
conversion of a share of Series C Preferred Stock, adjusted as hereinafter
provided, is referred to in this Article IV(C) as the "SERIES C CONVERSION
RATIO." The Series C Conversion Ratio as of August 3, 1998 is one, subject to
adjustment from time to time pursuant to Article IV(C), paragraph (7)(h) hereof.
Notwithstanding any call for redemption pursuant to Article IV(C), paragraph
(5), the right to convert shares so called for redemption shall terminate at the
close of business on the date immediately preceding the date fixed for such
redemption unless the Corporation shall default in making payment of the amount
payable upon such redemption.


                                       27
   28

               (b)  In order to exercise the conversion privilege and upon the
occurrence of a Series C Trigger Event, the holder of the shares of Series C
Preferred Stock to be converted shall surrender the certificate representing
such shares at the office of the Corporation, with, in the case of any
conversion pursuant to Article IV(C), paragraph (7)(a)(i), a written notice of
election to convert completed and signed, specifying the number of shares to be
converted. Unless the shares issuable on conversion are to be issued in the same
name as the name in which such shares of Series C Preferred Stock are
registered, each share surrendered for conversion shall, subject to the
provisions of the Securityholders Agreement, be accompanied by instruments of
transfer, in form satisfactory to the Corporation, duly executed by the holder
or the holder's duly authorized attorney and an amount sufficient to pay any
transfer or similar tax.

               (ii) As promptly as practicable after the surrender by the holder
of the certificates for shares of Series C Preferred Stock as aforesaid, the
Corporation shall issue and shall deliver to such holder, or on the holder's
written order to the holder's transferee, a certificate or certificates for the
whole number of shares of Common Stock issuable upon the conversion of such
shares in accordance with the provisions of this Article IV(C), paragraph (7).

               (iii) Each conversion shall be deemed to have been effected (x)
in the case of any conversion pursuant to Article IV(C), paragraph 7(a)(i),
immediately prior to the close of business on the date on which the certificates
for shares of Series C Preferred Stock shall have been surrendered and such
notice received by the Corporation as aforesaid or (y) in the case of any
conversion pursuant to Article IV(C), paragraph 7(a)(ii), on the date of the
Series C Trigger Event, and the person in whose name or names any certificate or
certificates for shares of Common Stock shall be issuable upon such conversion
shall be deemed to have become the holder of record of the shares of Common
Stock represented thereby at such time on such date and such conversion shall be
into a number of shares of Common Stock equal to the product of the number of
shares of Series C Preferred Stock surrendered times the Series C Conversion
Ratio in effect at such time on such date. All shares of Common Stock delivered
upon conversion of the Series C Preferred Stock will upon delivery be duly and
validly issued and fully paid and non-assessable, free of all liens and charges
and not subject to any preemptive rights. Upon the surrender of certificates
representing shares of Series C Preferred Stock, such shares shall no longer be
deemed to be outstanding and all rights of a holder with respect to such shares
surrendered for conversion shall immediately terminate except the right to
receive the Common Stock and other amounts payable pursuant to this Article
IV(C), paragraph (7).

               (C)       [Purposely left blank]

               (d)(i)    Upon delivery to the Corporation by a holder of shares 
of Series C Preferred Stock of a notice of election to convert, the right of the
Corporation to redeem such shares of Series C Preferred Stock shall terminate,
regardless of whether a notice of redemption has been mailed as aforesaid.

               (ii)      From the date of delivery by a holder of shares of 
Series C Preferred Stock of such holder's shares of Series C Preferred Stock
(and in the case of any conversion pursuant to Article IV(C), paragraph
7(a)(ii), upon the occurrence of a Series C Trigger Event), in lieu of dividends
on such Series C Preferred Stock pursuant to Article IV(C), paragraph (3), such
Series C Preferred Stock shall participate equally and ratably with the holders
of shares of Common Stock in all dividends paid on the Common Stock as if such
shares of Series C Preferred Stock 


                                       28
   29

had been converted to shares of Common Stock at the time of such delivery or
Series C Trigger Event.

               (iii)     Except to the extent provided above in Article IV(C),
paragraph (7)(d)(ii) and in Article IV(C), paragraph (7)(h), the Corporation
shall make no payment or adjustment for accrued and unpaid dividends on the
shares of Series C Preferred Stock, whether or not in arrears, on conversion of
such shares or for dividends in cash on the shares of Common Stock issued upon
such conversion.

               (e)(i)    The Corporation covenants that it will at all times
reserve and keep available, free from preemptive rights, such number of its
authorized but unissued shares of Common Stock as shall be required for the
purpose of effecting conversions of the Series C Preferred Stock.

               (ii)      Prior to the delivery of any securities which the
Corporation shall be obligated to deliver upon conversion of the Series C
Preferred Stock, the Corporation shall comply with respect to the issuance of
such securities with all applicable federal and state laws and regulations which
require action to be taken by the Corporation.

               (f)       The Corporation will pay any and all documentary stamp 
or similar issue or transfer taxes payable in respect of the issue or delivery
of shares of Common Stock on conversion of the Series C Preferred Stock pursuant
hereto; provided that the Corporation shall not be required to pay any tax which
may be payable in respect of any transfer involving the issue or delivery of
shares of Common Stock in a name other than that of the holder of the Series C
Preferred Stock to be converted and no such issue or delivery shall be made
unless and until the person requesting such issue or delivery has paid to the
Corporation the amount of any such tax or has established, to the satisfaction
of the Corporation, that such tax has been paid.

               (g)       In connection with the conversion of any shares of 
Series C Preferred Stock, no fractions of shares of Common Stock shall be
issued, but in lieu thereof the Corporation shall pay a cash adjustment in
respect of such fractional interest in an amount equal to such fractional
interest multiplied by the Daily Price per share of Common Stock on the business
day on which such shares of Series C Preferred Stock are deemed to have been
converted.

               (h)(i)    In case the Corporation shall at any time after August 
3, 1998 (I) declare a dividend or make a distribution on Common Stock payable in
Common Stock, (II) subdivide or split the outstanding Common Stock, (III)
combine or reclassify the outstanding Common Stock into a smaller number of
shares, (IV) issue any shares of its capital stock in a reclassification of
Common Stock (including any such reclassification in connection with a
consolidation or merger in which the Corporation is the continuing corporation,
other than any such consolidation or merger which results in the payment to the
holders of Series C Preferred Stock of the liquidation preference as provided in
Article IV(C), paragraph (4)), or (V) consolidate with, or merge with or into,
any other Person (other than any such consolidation or merger which results in
the payment to the holders of Series C Preferred Stock of the liquidation
preference as provided in Article IV(C), paragraph (4)), the Series C Conversion
Ratio in effect at the time of the record date for such dividend or distribution
or of the effective date of such subdivision, split, combination, consolidation,
merger or reclassification shall be proportionately adjusted so that 


                                       29
   30

the conversion of the Series C Preferred Stock after such time shall entitle the
holder to receive the aggregate number of shares of Common Stock or other
securities of the Corporation (or shares of any security into which such shares
of Common Stock have been combined, consolidated, merged or reclassified
pursuant to clause (III), (IV) or (V) above) which, if this Series C Preferred
Stock had been converted immediately prior to such time, such holder would have
owned upon such conversion and been entitled to receive by virtue of such
dividend, distribution, subdivision, split, combination, consolidation, merger
or reclassification, assuming such holder of Common Stock of the Corporation (x)
is not a constituent person, or an affiliate of a constituent person and (y)
failed to exercise any rights of election as to the kind or amount of
securities, cash and other property receivable upon such reclassification,
change, consolidation, merger, recapitalization, sale or transfer (provided,
that if the kind or amount of securities, cash and other property receivable
upon such reclassification, change, consolidation, merger, recapitalization,
sale or transfer is not the same for each non-electing share of Common Stock of
the Corporation held immediately prior to such reclassification, change,
consolidation, merger, recapitalization, sale or transfer by other than a
constituent person or an affiliate thereof, then for the purpose of this Article
IV(C), subparagraph (h) the kind and amount of securities, cash and other
property receivable upon such reclassification, change, consolidation, merger,
recapitalization, sale or transfer by each non-electing share shall be deemed to
be the kind and amount so receivable per share by a plurality of the
non-electing shares). Such adjustment shall be made successively whenever any
event listed above shall occur.

               (ii)      In case the Corporation shall at any time after August 
3, 1998 and until August 3, 1999 issue or sell any Common Stock (other than
Common Stock issued (I) upon conversion of the Series A Preferred Stock, the
Series B Preferred Stock, the Series C Preferred Stock or the Notes, (II)
pursuant to the Corporation's stock option plans or pursuant to any other Common
Stock related employee compensation plan of the Corporation approved by the
Corporation's Board of Directors, (III) upon exercise or conversion of any
security the setting of a record date for which or issuance of which caused an
adjustment under Article IV(C), paragraph (7)(h)(iii) or (h)(iv) hereto (IV)
upon exercise of warrants issued to lenders of the Corporation including,
without limitation, pursuant to the Bridge Securities Purchase Agreement or (V)
in connection with any bona fide, arms-length direct or indirect merger
acquisition or similar transaction) without consideration or for a consideration
per share less than the Conversion Price Per Common Share then in effect, the
Series C Conversion Ratio in effect immediately prior thereto shall be adjusted
to an amount equal to the quotient of the price per share at which the
Corporation issued or sold, or is deemed to have issued or sold the shares of
securities in the dilutive financing multiplied by the Series C Conversion Ratio
then in effect divided by the Conversion Price Per Common Share (for the Series
C Preferred Stock) then in effect. In case the Corporation shall at any time on
or after August 3, 1999 issue or sell any Common Stock (other than Common Stock
issued (I) upon conversion of the Series A Preferred Stock, the Series B
Preferred Stock, the Series C Preferred Stock or the Notes, (II) pursuant to the
Corporation's stock option plans or pursuant to any other Common Stock related
employee compensation plan of the Corporation approved by the Corporation's
Board of Directors, (III) upon exercise or conversion of any security the
setting of a record date for which or issuance of which caused an adjustment
under Article IV(C), paragraphs (7)(h)(iii) or (h)(iv) hereof, (IV) upon
exercise of warrants issued to lenders of the Corporation including, without
limitation, pursuant to the Bridge Securities Purchase Agreement or (V) in
connection with any bona fide, arms-length direct or indirect merger,
acquisition or similar transaction) without consideration or for a consideration
per share less than the Conversion Price Per Common Share then in effect the


                                       30
   31

Series C Conversion Ratio to be in effect after such issuance or sale shall
be determined by multiplying the Series C Conversion Ratio in effect immediately
prior to such issuance or sale by a fraction, (A) the numerator of which shall
be the sum of (x) the product of the aggregate number of shares of Common Stock
outstanding immediately after such issuance or sale and the Current Valuation
Per Common Share immediately prior to such issuance or sale plus (y) the
aggregate of the product of each share of Fully Diluted Common Stock (other than
shares of Common Stock included in (A)(x) or employee stock options) outstanding
immediately prior to such issuance or sale and the Exercise Price applicable to
such share of Fully Diluted Common Stock and (B) the denominator of which shall
be the sum of (x) the number of shares of Common Stock outstanding immediately
prior to the time of such issuance or sale multiplied by the Current Valuation
Per Common Share immediately prior to such issuance or sale, plus (y) the
aggregate of the product of each share of Fully Diluted Common Stock (other than
shares of Common Stock included in (B)(x) or employee stock options) outstanding
immediately prior to such issuance or sale and the Exercise Price applicable to
such share of Fully Diluted Common Stock, plus (z) the aggregate consideration,
if any, to be received by the Corporation upon such issuance or sale. In case
any portion of the consideration to be received by the Corporation shall be in a
form other than cash, the fair market value of such noncash consideration shall
be utilized in the foregoing computation. Such fair market value shall be
determined by the Board of Directors of the Corporation; provided that if the
holders of 25% of the Series C Preferred Stock shall object to any such
determination, the Board of Directors shall retain an independent appraiser
reasonably satisfactory to such holders to determine such fair market value. The
holders shall be notified promptly of any consideration other than cash to be
received by the Corporation and furnished with a description of the
consideration and the fair market value thereof, as determined by the Board of
Directors.

               (iii)     In case the Corporation shall at any time after August 
3, 1998 fix a record date for the issuance of rights, options or warrants to the
holders of its Common Stock or other securities of the Corporation entitling
such holders to subscribe for or purchase shares of Common Stock (or securities
convertible into shares of Common Stock) at a price per share of Common Stock
(or having a conversion price per share of Common Stock, if a security
convertible into shares of Common Stock) less than the then Conversion Price Per
Common Share on such record date, the maximum number of shares of Common Stock
issuable upon exercise of such rights, options or warrants (or conversion of
such convertible securities) shall be deemed to have been issued and outstanding
as of such record date and the Series C Conversion Ratio shall be adjusted
pursuant to Article IV(C), paragraph (7)(h)(ii) hereof, as though such maximum
number of shares of Common Stock had been so issued for the aggregate
consideration payable by the holders of such rights, options, warrants or
convertible securities prior to their receipt of such shares of Common Stock. In
case any portion of such consideration shall be in a form other than cash, the
fair market value of such noncash consideration shall be determined as set forth
in Article IV(C), paragraph (7)(h)(ii) hereof. Such adjustment shall be made
successively whenever such record date is fixed; and in the event that such
rights, options or warrants are not so issued or expire unexercised, or in the
event of a change in the number of shares of Common Stock to which the holders
of such rights, options or warrants are entitled (other than pursuant to
adjustment provisions therein comparable to those contained in this Article
IV(C), paragraph (7)(h)), the Series C Conversion Ratio shall again be adjusted
to be the Series C Conversion Ratio which would then be in effect if such record
date had not been fixed, in the former event, or the Series C Conversion Ratio
which would then be in effect if such


                                       31
   32

holder had initially been entitled to such changed number of shares of Common
Stock, in the latter event.

               (iv)      In case the Corporation shall at any time after August 
3, 1998 issue rights, options (other than options issued pursuant to a plan
described in clause II of Article IV(C), paragraph (h)(ii)) or warrants (other
than warrants described in clause IV of Article IV(C), paragraph (h) (ii))
entitling the holders thereof to subscribe for or purchase Common Stock (or
securities convertible into shares of Common Stock) or shall issue convertible
securities, and the price per share of Common Stock of such rights, options,
warrants or convertible securities (including, in the case of rights, options or
warrants, the price at which they may be exercised) is less than the then
Conversion Price Per Common Share, the maximum number of shares of Common Stock
issuable upon exercise of such rights, options or warrants or upon conversion of
such convertible securities shall be deemed to have been issued and outstanding
as of the date of such sale or issuance, and the Series C Conversion Ratio shall
be adjusted pursuant to Article IV(C), paragraph (7)(h)(ii) hereof as though
such maximum number of shares of Common Stock had been so issued for an
aggregate consideration equal to the aggregate consideration paid for such
rights, options, warrants or convertible securities and the aggregate
consideration payable by the holders of such rights, options, warrants or
convertible securities prior to their receipt of such shares of Common Stock. In
case any portion of such consideration shall be in a form other than cash, the
fair market value of such noncash consideration shall be determined as set forth
in Article IV(C), paragraph (7)(h)(ii) hereof. Such adjustment shall be made
successively whenever such rights, options, warrants or convertible securities
are issued; and in the event that such rights, options or warrants expire
unexercised, or in the event of a change in the number of shares of Common Stock
to which the holders of such rights, options, warrants or convertible securities
are entitled (other than pursuant to adjustment provisions therein comparable to
those contained in this Article IV(C), paragraph (7)(h)), the Series C
Conversion Ratio shall again be adjusted to be the Series C Conversion Ratio
which would then be in effect if such rights, options, warrants or convertible
securities had not been issued, in the former event, or the Series C Conversion
Ratio which would then be in effect if such holders had initially been entitled
to such changed number of shares of Common Stock, in the latter event. No
adjustment of the Series C Conversion Ratio shall be made pursuant to this
Article IV(C), paragraph (7)(h)(iv) to the extent that the Series C Conversion
Ratio shall have been adjusted pursuant to Article IV(C), paragraph (7)(h)(iii)
upon the setting of any record date relating to such rights, options, warrants
or convertible securities and such adjustment fully reflects the number of
shares of Common Stock to which the holders of such rights, options, warrants or
convertible securities are entitled and the price payable therefor.

               (v)       In case the Corporation shall at any time after August 
3, 1998 fix a record date for the making of a distribution to holders of Common
Stock (including any such distribution made in connection with a consolidation
or merger in which the Corporation is the continuing corporation, other than any
such consolidation or merger which results in the payment to holders of Series C
Preferred Stock of the liquidation preference as provided in Article IV(C),
paragraph (4)) of evidences of indebtedness, assets or other property (other
than dividends payable in Common Stock or rights, options or warrants referred
to in, and for which an adjustment is made pursuant to Article IV(C), paragraph
(7)(h)(iii) hereof), the Series C Conversion Ratio to be in effect after such
record date shall be determined by multiplying the Series C Conversion Ratio in
effect immediately prior to such record date by a fraction, (A) the numerator of
which shall be the Current Valuation Per Common Share on such record date, and


                                       32
   33

(B) the denominator of which shall be the Current Valuation Per Common Share on
such record date, less the fair market value (determined as set forth in Article
IV(C), paragraph (7)(h)(ii) hereof) of the portion of the assets, other property
or evidence of indebtedness so to be distributed which is applicable to one
share of Common Stock. Such adjustments shall be made successively whenever such
a record date is fixed; and in the event that such distribution is not so made,
the Series C Conversion Ratio shall again be adjusted to be the Series C
Conversion Ratio which would then be in effect if such record date had not been
fixed.

               (vi)      For purposes of any computation under Article IV(C),
paragraph (7)(g) or paragraph (7)(h), the number of shares of Common Stock
outstanding at any given time shall not include shares owned or held by or for
the account of the Corporation.

               (vii)     No adjustment to the Series C Conversion Ratio pursuant
to Article IV(C), paragraphs (7)(h)(ii), (iii), (iv) and (v) above shall be
required unless such adjustment would require an increase or decrease of at
least 1% in the Series C Conversion Ratio; provided however, that any
adjustments which by reason of this Article IV(C), paragraph (7)(h)(vii) are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations under this Article IV(C), paragraph
(7)(h) shall be made to the nearest four decimal points.

               (viii)    In the event that, at any time as a result of the
provisions of this Article IV(C), paragraph (7)(h), the holders of the Series C
Preferred Stock upon subsequent conversion shall become entitled to receive any
shares of capital stock of the Corporation other than Common Stock, the number
of such other shares so receivable upon conversion of the Series C Preferred
Stock shall thereafter be subject to adjustment from time to time in a manner
and on terms as nearly equivalent as practicable to the provisions contained
herein.

               (ix)      In the event:

               (A)       of any capital reorganization or reclassification of 
               the Common Stock (other than a subdivision or combination of the
               outstanding Common Stock and other than a change in par value of
               the Common Stock) or of any consolidation or merger to which the
               Corporation is a party and for which approval of any stockholders
               of the Corporation is required (other than a consolidation or
               merger in which the Corporation is the continuing corporation and
               that does not result in any reclassification or change of the
               Common Stock outstanding), or of the conveyance or transfer of
               the properties and assets of the Corporation substantially as an
               entirety; or

               (B)       of the voluntary or involuntary dissolution, 
               liquidation or winding-up of the Corporation; or

               (C)       the Corporation proposes to take any action (other than
               actions of the character described in Article IV(C), paragraph
               (7)(h)(i)(I) or (II)) that would require an adjustment pursuant
               to this Article IV(C), paragraph (7)(h) to the number of shares
               purchasable upon conversion;

then the Corporation shall cause to be mailed by first-class mail to the holders
of Series C Preferred Stock, at least five days prior to the applicable record
or effective date hereinafter 


                                       33
   34

specified (10 days in the case of the events referred to in clauses (A) and (B)
above), a notice stating (x) the date as of which the holders of Common Stock of
record to be entitled to receive any such rights, warrants or distributions are
to be determined, or (y) the date on which any such consolidation, merger,
conveyance, transfer, dissolution, liquidation or winding-up is expected to
become effective, and the date as of which it is expected that holders of Common
Stock of record shall be entitled to exchange their shares of Common Stock for
securities or other property, if any, deliverable upon such reorganization,
reclassification, consolidation, merger, conveyance, transfer, dissolution,
liquidation or winding-up.

               (i)  All adjustments pursuant to this Article IV(C), paragraph 
(7) shall be notified to the holders of this Series C Preferred Stock and such
notice shall be accompanied by a schedule of computation of the adjustments.

               (8)  Voting Rights.

               (a)  Except as otherwise provided by applicable law, the holders
of the shares of Series C Preferred Stock (i) shall be entitled to vote with the
holders of the Common Stock on all matters submitted for a vote of holders of
Common Stock, (ii) shall be entitled to a number of votes equal to the number of
votes to which shares of Common Stock issuable upon conversion of such shares of
