                        CERTIFICATE OF DESIGNATION OF
                   SERIES G CONVERTIBLE PREFERRED STOCK OF
                     ILLINOIS SUPERCONDUCTOR CORPORATION



                 The undersigned, Edward W. Laves and Stephen G. Wasko, hereby
certify that:

                 I.       They are the duly elected and acting President and
Secretary, respectively, of Illinois Superconductor Corporation, a Delaware
corporation (the "Company").

                 II.      The Certificate of Incorporation of the Company
authorizes 100,000 shares of preferred stock, par value $.001 per share, 900
shares of which are currently issued and outstanding.

                 III.     The following is a true and correct copy of
resolutions duly adopted by the Board of Directors of the Company (the "Board
of Directors") at a meeting duly held on October 16, 1997, which constituted
all requisite action on the part of the Company for adoption of such
resolutions.

                                 RESOLUTIONS

                 WHEREAS, the Board of Directors is authorized to provide for
the issuance of the shares of preferred stock in series, and by filing a
certificate pursuant to the applicable law of the State of Delaware, to
establish from time to time the number of shares to be included in each such
series, and to fix the designations, relative rights, qualifications,
limitations or restrictions of the shares of each such series.

                 WHEREAS, the Board of Directors desires, pursuant to its
authority as aforesaid, to designate a new series of preferred stock, set the
number of shares constituting such series and fix the rights, preferences,
privileges and restrictions of such series.

                 NOW, THEREFORE, BE IT RESOLVED, that the Board of Directors
hereby designates a new series of preferred stock and the number of shares
constituting such series and fixes the rights, preferences, privileges and
restrictions relating to such series as follows:

                 Section 1.       Designation, Amount and Par Value.  The
series of preferred stock shall be designated as the Series G Convertible
Preferred Stock (the "Preferred Stock"), and the number of shares so designated
shall be 700 (which shall not be subject to increase without the consent of the
holders of a majority of the then outstanding Preferred Stock hereof).  Each
share of Preferred Stock shall have a par value of $.001 per share and a stated
value of $5,000 per share (the "Stated Value").



   2

                 Section 2.       Dividends.

                 (a)      Holders of Preferred Stock shall be entitled to
receive, when and as declared by the Board of Directors out of funds legally
available therefor, and the Company shall pay, cumulative dividends at the rate
per share (as a percentage of the Stated Value per share) equal to 5% per
annum, payable, in cash or shares of Common Stock (as defined in Section 7) at
the option of the Company upon two Business Days' written notice, quarterly in
arrears on March 31, June 30, September 30 and December 31 of each year (the
"Dividend Payment Date"), commencing on December 31, 1997, through the
Conversion Date (as defined in Section 5(a)(i)) applicable to each share of
Preferred Stock in accordance with the delivery terms hereof.  Dividends on the
Preferred Stock shall be calculated on the basis of a 360-day year, shall
accrue daily commencing the Original Issue Date (as defined in Section 7), and
shall be deemed to accrue on such Dividend Payment Date whether or not earned
or declared and whether or not there are profits, surplus or other funds of the
Company legally available for the payment of dividends.  The party of record
that holds the Preferred Stock on the fifteenth day of the calendar month
immediately preceding a Dividend Payment Date will be entitled to receive the
dividend payment for such Dividend Payment Date and any other accrued and
unpaid dividends which accrued prior to such Dividend Payment Date, without
regard to any sale or disposition of such Preferred Stock subsequent to the
applicable record date but prior to the applicable Dividend Payment Date.  If,
at the Company's election, dividends are paid on the Preferred Stock in the
form of shares of Common Stock, such shares of Company Stock shall be valued at
the Conversion Price (as defined in Section 5(c)(i)) on the Trading Day (as
defined in Section 7) immediately preceding the date on which such dividend is
paid.  Except as otherwise provided herein, if at any time the Company pays
less than the total amount of dividends then accrued on account of the
Preferred Stock, such payment shall be distributed ratably among the holders of
the Preferred Stock based upon the number of shares held by each holder.
Payment of dividends on the Preferred Stock is further subject to the
provisions of Section 5(c)(i).

                 (b)      Notwithstanding anything to the contrary contained
herein, the Company may not issue shares of Common Stock in payment of
dividends (and must deliver cash in respect thereof) on the Preferred Stock if:

                          (i)  the number of shares of Common Stock at the time
authorized, unissued and unreserved for all purposes, or held as treasury
stock, is insufficient to issue such dividends to be paid in shares of Common
Stock;

                          (ii)  such shares are not registered for resale
pursuant to an effective registration statement and covered by a current
related prospectus that names the recipient of such dividend as a selling
stockholder thereunder and may not be sold without volume restrictions pursuant
to Rule 144 promulgated under the Securities Act of 1933, as amended (the
"Securities Act"), as determined by counsel to the Company pursuant to a
written opinion letter, addressed to the Company's transfer agent, in the form
and substance reasonably acceptable to the holder;





                                     -2-
   3
                          (iii)  such shares are not listed on the Nasdaq
National Market, The Nasdaq SmallCap Market, the New York Stock Exchange, the
American Stock Exchange or any other exchange or quotation system on which the
Common Stock is then listed for trading; or

                          (iv)  the issuance of such shares would result in the
recipient thereof and its Affiliates beneficially owning, in accordance with
Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended
(but without taking into account shares of Common Stock that would otherwise be
deemed beneficially owned by virtue of the conversion of the Shares or exercise
of warrants of the Company having similar limitations on exercise), more than
9.999% of the issued and outstanding shares of Common Stock (with the recipient
having the right to decrease such percentage applicable to it, immediately upon
delivering written notice to the Company).

                 (c)      So long as any Preferred Stock shall remain
outstanding, the Company shall not redeem, purchase or otherwise acquire
directly or indirectly any Junior Securities (as defined in Section 7), nor
shall the Company directly or indirectly pay or declare any dividend or make
any distribution (other than a dividend or distribution described in Section
5(c)(ii) or 5(c)(iv)) in excess, of in the aggregate, $250,000 upon, nor shall
any distribution be made in respect of, any Junior Securities, nor shall any
monies in excess, of in the aggregate, $1,000,000 be set aside for or applied
to the purchase or redemption (through a sinking fund or otherwise) of any
Junior Securities.

                 Section 3.       Voting Rights.  Except as otherwise provided
herein and as otherwise required by law, the Preferred Stock shall have no
voting rights.  However, so long as any shares of Preferred Stock are
outstanding, the Company shall not, without the affirmative vote of the holders
of a majority of the shares of the Preferred Stock then outstanding, (a) alter
or change adversely the powers, preferences or rights given to the Preferred
Stock, (b) alter or amend this Certificate of Designation or (c) authorize or
create any class of stock ranking as to dividends or distribution of assets
upon a Liquidation (as defined in Section 4) senior to, prior to or pari passu
with the Preferred Stock, except for any other series of preferred stock of the
Company issued and sold in accordance with the Convertible Preferred Stock
Purchase Agreement, dated as of June 6, 1997, by and between the Company and
Southbrook International Investments, Ltd.

                 Section 4.       Liquidation.  Upon any liquidation,
dissolution or winding-up of the Company, whether voluntary or involuntary (a
"Liquidation"), the holders of Preferred Stock shall be entitled to receive in
cash out of the assets of the Company, whether such assets are capital or
surplus, for each share of Preferred Stock an amount equal to the Stated Value
plus all accrued but unpaid dividends per share, whether declared or not,
before any distribution or payment shall be made to the holders of any Junior
Securities, and if the assets of the Company shall be insufficient to pay in
full the amounts due to the holders of the Preferred Stock and holders of
shares of other classes or series of capital stock of the Company that rank
pari passu with the Preferred Stock as to distributions of assets, then the
entire assets to be distributed to the holders of Preferred Stock and the
holders of such capital stock ranking pari passu shall be





                                     -3-
   4
distributed among the holders of Preferred Stock and the holders of such
capital stock ranking pari passu ratably in accordance with the respective
amounts that would be payable on such shares if all amounts payable thereon
were paid in full.  A sale, conveyance or disposition of all or substantially
all of the assets of the Company or the effectuation by the Company of a
transaction or series of related transactions in which more than 50% of the
voting power of the Company is disposed of, or a consolidation or merger of the
Company with or into any other company or companies shall not be treated as a
Liquidation, but instead shall be subject to the provisions of Section 5.  The
Company shall mail written notice of any such Liquidation, not less than 45
days prior to the payment date stated therein, to each record holder of
Preferred Stock.

                 Section 5.       Conversion.

                 (a)(i)  Each share of Preferred Stock shall be convertible
into shares of Common Stock (subject to reduction pursuant to Section 5(a)(ii)
and Section 5(a)(iii) below and Section 3.8 of the Purchase Agreement (as
defined in Section 7)) at the Conversion Ratio (as defined in Section 7) at the
option of the holder in whole or in part at any time after the Original Issue
Date.  The holder shall effect conversions by surrendering the certificate or
certificates representing the shares of Preferred Stock to be converted to the
Company, together with a fully executed notice of conversion in the form of
conversion notice attached hereto as Exhibit A (the "Conversion Notice").  Each
Conversion Notice shall specify the number of shares of Preferred Stock to be
converted and the date on which such conversion is to be effected, which date
may not be prior to the date such Conversion Notice is delivered hereunder (the
"Conversion Date").  If no Conversion Date is specified in a Conversion Notice,
the Conversion Date shall be the date that the Conversion Notice is deemed
delivered pursuant to Section 5(i).  Subject to Sections 5(b), 5(a)(ii) hereof
and Section 3.8 of the Purchase Agreement, each Conversion Notice, once given,
shall be irrevocable.  If the holder is converting less than all shares of
Preferred Stock represented by the certificate or certificates tendered by the
holder with the Conversion Notice, or if a conversion hereunder cannot be
effected in full for any reason, the Company shall promptly deliver to such
holder (in the manner and within the time set forth in Section 5(b)) a
certificate for such number of shares as have not been converted.

                          (ii)  Certain Regulatory Approval.  If on the
Conversion Date applicable to any conversion under this Section 5(a), (A) the
Common Stock is then listed for trading on  the Nasdaq National Market or if
the rules of The Nasdaq Stock Market, Inc. are hereafter amended to extend Rule
4460(i) promulgated thereby (or any successor or replacement provision thereof)
to The Nasdaq SmallCap Market or the American Stock Exchange and the Company's
Common Stock is then listed for trading on such market or exchange, (B) the
Conversion Price then in effect is such that the aggregate number of shares of
Common Stock that would then be issuable upon conversion of all outstanding
shares of Preferred Stock, together with any shares of Common Stock previously
issued upon conversion of Preferred Stock and in respect of payment of
dividends hereunder, would equal or exceed 20% of the number of shares of
Common Stock outstanding on the Original Issue Date (the "Issuable Maximum"),
and (C) the Company has not previously obtained Stockholder Approval (as
defined below), then the





                                     -4-
   5
Company shall issue to the holder so requesting conversion of Preferred Stock
an amount of shares of Common Stock equal to the Issuable Maximum and, with
respect to any shares of Common Stock that otherwise would have been issuable
to such holder in respect of the Conversion Notice at issue or in respect of
payment of dividends hereunder in excess of the Issuable Maximum, the holder
shall have the option, by written notice, to require the Company to either (1)
as promptly as possible, but in no event later than 60 days after such
Conversion Date, convene a meeting of the holders of the Common Stock and use
its best efforts to obtain the Stockholder Approval or (2) redeem the balance
of the Preferred Stock subject to such Conversion Notice for cash at a price
per share equal to the product of (i) the average Per Share Market Value for
the five (5) Trading Days immediately preceding (A) the Conversion Date or (B)
the date of payment in full by the Company of such redemption price, whichever
is greater, and (ii) the Conversion Ratio calculated on the Conversion Date;
provided, however, that if the holder has requested that the Company obtain
Stockholder Approval under (1) above and the Company fails for any reason to
obtain such Stockholder Approval within the time period set forth in (1) above,
the Company shall be obligated to redeem the Preferred Stock not converted as a
result of the provisions of this Section in accordance with the provisions of
(2) above, and in such case the interest contemplated by the immediately
succeeding sentence shall be deemed to accrue from the Conversion Date.  If the
holder has requested that the Company redeem shares of Preferred Stock pursuant
to this Section and the Company fails for any reason to pay the redemption
price under (2) above within seven days after the notice of redemption is
deemed delivered pursuant to Section 5(h), the Company will pay interest on
such redemption price in cash at a rate of 15% per annum to the converting
holder of Preferred Stock, accruing from the Conversion Date until the
redemption price plus any accrued interest thereon is paid in full; provided,
however, if any portion of the redemption price under this Section 5(a)(ii)
shall not be paid by the Company within seven days of such notice of redemption
being delivered, the holder by written notice given to the Company within 30
days of such 7th day, may elect to invalidate ab initio such redemption and the
Company shall, within three Trading Days of receipt of such notice, return to
such holder all shares of Preferred Stock for which the redemption price has
not been paid.  "Stockholder Approval" means the approval by a majority of the
total votes cast on the proposal, in person or by proxy, at a meeting of the
stockholders of the Company held in accordance with the Company's Certificate
of Incorporation and By-laws, as amended and in effect on the date thereof, of
the issuance by the Company of shares of Common Stock exceeding the Issuable
Maximum as a consequence of the conversion of Preferred Stock into Common Stock
at a price less than the greater of the book or market value on the Original
Issue Date as and to the extent required pursuant to Rule 4460(i) of The Nasdaq
Stock Market, Inc. or Rule 713 of the American Stock Exchange (or any successor
or replacement provision thereof), as applicable.

                             (iii)         If on any Conversion Date applicable
to a conversion under Section 5(a) or a redemption pursuant to Section 6, the
average Per Share Market Value for the five Trading Days immediately preceding
such Conversion Date exceeds the Initial Conversion Price (as defined in
Section 5(c(i)), as adjusted pursuant to Section 5(c), by more than 50%, the
Conversion Price otherwise applicable to such conversion or repayment shall be
increased by an amount equal to 50% of the difference between (A) the average
Per Share Market Value for





                                     -5-
   6
the five Trading Days immediately preceding such Conversion Date, and (B) 150%
of the Initial Conversion Price, as adjusted pursuant to Section 5(c).

                 (b)      Not later than three Trading Days after the
Conversion Date, the Company will deliver to the holder (i) a certificate or
certificates which shall be free of restrictive legends and trading
restrictions (other than those required by Section 3.1(b) of the Purchase
Agreement) representing the number of shares of Common Stock being acquired
upon the conversion of shares of Preferred Stock (subject to reduction pursuant
to Sections 5(a)(ii), 5(a)(iii) and Section 3.8 of the Purchase Agreement) and
(ii) one or more certificates representing the number of shares of Preferred
Stock not converted, if any, and (iii) a check drawn on the account of the
Company and payable to the holder in an amount equal to any accrued but unpaid
dividends, if the Company elects to pay such dividends in cash; provided,
however, that the Company shall not be obligated to issue certificates
evidencing the shares of Common Stock issuable upon conversion of any shares of
Preferred Stock until certificates evidencing such shares of Preferred Stock
are either delivered for conversion to the Company, or the holder of such
Preferred Stock notifies the Company that such certificates have been lost,
stolen or destroyed and provides a bond (or other adequate security reasonably
acceptable to the Company) reasonably satisfactory to the Company to indemnify
the Company from any loss incurred by it in connection therewith.  The Company
shall, upon request of the holder, use its best efforts to deliver any
certificate or certificates required to be delivered by the Company under this
Section electronically through The Depository Trust Corporation or another
established clearing corporation performing similar functions.  If in the case
of any Conversion Notice such certificate or certificates, including for
purposes hereof, any shares of Common Stock to be issued on the Conversion Date
on account of accrued but unpaid dividends hereunder, are not delivered to or
as directed by the applicable holder by the third Trading Day after the
Conversion Date, the holder shall be entitled by written notice to the Company
at any time on or before its receipt of such certificate or certificates
thereafter, to rescind such conversion, in which event the Company shall
immediately return the certificates representing the shares of Preferred Stock
tendered for conversion.  If the Company fails to deliver to the holder such
certificate or certificates pursuant to this Section, including for purposes
hereof, any shares of Common Stock to be issued on the Conversion Date on
account of accrued but unpaid dividends hereunder, prior to the fifth Trading
Day after the Conversion Date, the Company shall pay to such holder, in cash,
an amount equal to the greater of (x) $1,500, as liquidated damages, and not as
a penalty, for each Trading Day after such fifth Trading Day until such
certificates are delivered and (y) the actual damages which such holder can
prove it has suffered as a direct result of the Company's failure to deliver to
such holder such certificate or certificates prior to the fifth Trading Day
after the Conversion Date.  If the Company fails to deliver to the holder such
certificate or certificates pursuant to this Section prior to the 20th day
after the Conversion Date, the Company shall, at the holder's option and upon
such holder's written notice, redeem such number of shares of Preferred Stock
then held by such holder, as requested by such holder.  The redemption price
per share shall be equal to the product of (A) the average Per Share Market
Value for the five (5) Trading Days immediately preceding (1) the Conversion
Date or (2) the date of payment in full by the Company of such redemption
price, whichever is greater, and (B) the Conversion Ratio calculated on the
Conversion Date.  If the holder has requested that the Company redeem shares





                                     -6-
   7
of Preferred Stock pursuant to this Section and the Company fails for any
reason to pay the redemption price above within seven days after such notice is
deemed delivered pursuant to Section 5(h), the Company will pay interest on the
redemption price at a rate of 15% per annum, in cash to such holder, accruing
from such seventh day until the redemption price and any accrued interest
thereon is paid in full; provided, however, if any portion of the redemption
price under this Section 5(b) shall not be paid by the Company within seven
days of such notice of redemption being delivered, the holder by written notice
given to the Company within 30 days of such 7th day, may elect to invalidate ab
initio such redemption and the Company shall, within three Trading Days of
receipt of such notice, return to such holder all shares of Preferred Stock for
which the redemption price has not been paid.

                 (c)      (i)     The conversion price ("Conversion Price")
applicable to conversions of Preferred Stock into Common Stock hereunder shall
be determined in accordance with this Section.  Subject to adjustment as
provided in this paragraph (c)(i), for any conversions that occur prior to the
earlier of (1) the date the Securities and Exchange Commission (the
"Commission") declares effective an Underlying Shares Registration Statement
(as defined below) or (ii) the 89th day after the Original Issue Date (such
period, the "Pre-Effective Period"), the Conversion Price for each share of
Preferred Stock shall equal the average Per Share Market Value for the five (5)
Trading Days immediately preceding the Original Issue Date (the "Initial
Conversion Price").  For all conversions occurring after the Pre- Effective
Period, subject to the immediately preceding sentence, the Conversion Price
shall be the lesser of (a) the Initial Conversion Price or (b) 101% of the
lowest average of the Per Share Market Value for any five (5) consecutive
Trading Days during the 60 Trading Days immediately preceding such Conversion
Date (which shall not include the date that such Conversion Notice is deemed
delivered hereunder pursuant to Section 5(h) below); provided, however, that in
no event shall the Conversion Price be calculated based on the Per Share Market
Value for any five (5) consecutive Trading Day period for which the Purchaser's
or any of its Affiliates' volume of trading in the Common Stock exceeds 20% of
the trading volume in the Common Stock (excluding any de minimis amount by
which the Purchaser or any of its Affiliates' inadvertently exceeds such 20%
limitation) during such five (5) consecutive Trading Day period as reported by
the Nasdaq National Market, The Nasdaq SmallCap Market, the New York Stock
Exchange, the American Stock Exchange or such other market or exchange on which
the Common Stock is traded (for example, if the Purchaser's or any of its
Affiliates' volume in the Common Stock exceeds such 20% level during Trading
Days 10-14, but does not exceed such level for Trading Days 11-15, then the
Conversion Price may be calculated based upon the Per Share Market Value for
Trading Days 11-15 but not for Trading Days 10-14).  Notwithstanding the
foregoing, if (a) the registration statement contemplated by the Registration
Rights Agreement, which among other things, requires the Company to register
the resale of the shares of Common Stock issuable upon conversion of the
Preferred Stock (the "Underlying Shares Registration Statement") is not filed
on or prior to the 30th day after the Original Issue Date, or (b) the Company
fails to file with the Commission a request for acceleration in accordance with
Rule 12d1-2 promulgated under the Securities Exchange Act of 1934, as amended,
within five (5) days of the date that the Company is notified (orally or in
writing, whichever is earlier) by the Commission that an Underlying Shares
Registration Statement will not be "reviewed" or is





                                     -7-
   8
advised that such Registration Statement is not subject to further review or
comment, or (c) if the Underlying Shares Registration Statement is not declared
effective by the Commission on or prior to the 90th day after the Original
Issue Date, or (d) if such Underlying Shares Registration Statement is filed
with and declared effective by the Commission but thereafter ceases to be
effective as to all Registrable Securities (as such term is defined in the
Registration Rights Agreement) at any time prior to the expiration of the
"Effectiveness Period" (as such term as defined in the Registration Rights
Agreement), without being succeeded within 10 Business Days by a subsequent
Underlying Shares Registration Statement filed with and declared effective by
the Commission, or (e) if trading in the Common Stock shall be suspended for
any reason for more than three consecutive Trading Days or five Trading Days in
the aggregate, or (f) if the conversion rights of the holders of Preferred
Stock hereunder are suspended for any reason, or (g) the Company postpones or
suspends the filing or effectiveness of any Registration Statement in excess of
20 consecutive days or 60 days in the aggregate during any twelve month period,
or (h) a holder of Registrable Securities must discontinue disposition of its
Registrable Securities pursuant to the fourth paragraph of Section 3(o) of the
Registration Rights Agreement (any such occurrence being referred to as an
"Event," and for purposes of clauses (a), (c), (f) and (h) the date on which
such Event occurs, or for purposes of clause (b) the date on which such five
(5) day period is exceeded, or for purposes of clause (d) the date which such
10 Business Day-period is exceeded, or for purposes of clause (e) the date on
which such three Trading Day period is exceeded, or for purposes of clause (g)
the date on which such 20 consecutive day or 60 aggregate day period is
exceeded, being referred to as an "Event Date"), the Conversion Price in effect
on a Conversion Date shall be decreased by 2.5% for each monthly anniversary of
an Event Date until the earlier to occur of the second month anniversary after
the Event Date and such time as the applicable Event is cured (e.g. if an Event
has not been cured on the first month anniversary of its Event Date, the
Conversion Price in effect on a Conversion Date shall be reduced to 97.5% of
such Conversion Price; if the Event has not been cured on the second month
anniversary of its Event Date, the Conversion Price in effect on a Conversion
Date shall be further reduced to 95% of such Conversion Price).  Commencing the
second month anniversary after the Event Date, at the option of each holder, to
be exercised by written notice, for each applicable monthly period either (a)
the Company shall pay to the holders of the Preferred Stock 2.5% of the product
of the number of outstanding shares of Preferred Stock and the Stated Value
(each holder being entitled to receive such portion of such amount as equals
its pro rata portion of the Preferred Stock then outstanding) in cash or (b)
the Conversion Price in effect on a Conversion Date shall be decreased by 2.5%
for each such additional month (to be effective in full on the monthly
anniversary of an applicable Event Date) as liquidated damages, and not as a
penalty, on the first day of each monthly anniversary of the Event Date, in
either case until such time as the applicable Event is cured.  Any decreased
Conversion Price in effect pursuant to this Section shall continue
notwithstanding the fact that the Event causing such decrease has been
subsequently cured.  If an Event is not cured by the third month anniversary of
an Event Date (or the second week anniversary of an Event Date for the purpose
of clause (f)), then the holder shall have the option by written notice to
require the Company to redeem its shares of Preferred Stock at an aggregate
purchase price equal to the product of (i) the average Per Share Market Value
for the five (5) Trading Days immediately preceding the holder's redemption
notice and (ii) the number of shares of Common Stock into





                                     -8-
   9
which the Preferred Stock held by such holder is convertible on the date of
such redemption notice.  If the holder has requested that the Company redeem
shares of Preferred Stock pursuant to this Section and the Company fails for
any reason to pay the redemption price within seven days after the notice of
redemption is deemed delivered pursuant to Section 5(h), the Company will pay
interest on such redemption price in cash at a rate of 15% per annum to such
holder of Preferred Stock, accruing from the date the notice of redemption is
deemed delivered until the redemption price plus any accrued interest thereon
is paid in full; provided, however, if any portion of the redemption price
under this Section 5(c)(i) shall not be paid by the Company within seven days
of such notice of redemption being delivered, the holder by written notice
given to the Company within 30 days of such 7th day, may elect to invalidate ab
initio such redemption and the Company shall, within three Trading Days of
receipt of such notice, return to such holder all shares of Preferred Stock for
which the redemption price has not been paid.  The provisions of this Section
are not exclusive and shall in no way limit the Company's obligations under the
Registration Rights Agreement.

                          (ii)    If the Company, at any time while any shares
of Preferred Stock are outstanding, (a) shall pay a stock dividend or otherwise
make a distribution or distributions on shares of its Junior Securities payable
in shares of Common Stock, (b) subdivide outstanding shares of Common Stock
into a larger number of shares, (c) combine outstanding shares of Common Stock
into a smaller number of shares, or (d) issue by reclassification of shares of
Common Stock any shares of capital stock of the Company, the Initial Conversion
Price shall be multiplied by a fraction of which the numerator shall be the
number of shares of Common Stock (excluding treasury shares, if any)
outstanding before such event and of which the denominator shall be the number
of shares of Common Stock outstanding after such event.  Any adjustment made
pursuant to this Section 5(c)(ii) shall become effective immediately after the
record date for the determination of stockholders entitled to receive such
dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision, combination or re-classification.

                          (iii)  If the Company, at any time while any shares
of Preferred Stock are outstanding, shall issue rights or warrants to all
holders of Common Stock entitling them to subscribe for or purchase shares of
Common Stock at a price per share less than the Per Share Market Value of
Common Stock at the record date mentioned below, the Initial Conversion Price
shall be multiplied by a fraction, of which the denominator shall be the number
of shares of Common Stock (excluding treasury shares, if any) outstanding on
the date of issuance of such rights or warrants plus the number of additional
shares of Common Stock offered for subscription or purchase, and of which the
numerator shall be the number of shares of Common Stock (excluding treasury
shares, if any) outstanding on the date of issuance of such rights or warrants
plus the number of shares which the aggregate offering price of the total
number of shares so offered would purchase at such Per Share Market Value.
Such adjustment shall be made whenever such rights or warrants are issued, and
shall become effective immediately after the record date for the determination
of stockholders entitled to receive such rights or warrants.  However, upon the
expiration of any right or warrant to purchase Common Stock the issuance of
which resulted in an adjustment in the Initial Conversion Price pursuant to
this Section





                                     -9-
   10
5(c)(iii), if any such right or warrant shall expire and shall not have been
exercised, the Initial Conversion Price shall immediately upon such expiration
be recomputed and effective immediately upon such expiration be increased to
the price which it would have been (but reflecting any other adjustments in the
Initial Conversion Price made pursuant to the provisions of this Section 5
after the issuance of such rights or warrants) had the adjustment of the
Initial Conversion Price made upon the issuance of such rights or warrants been
made on the basis of offering for subscription or purchase only that number of
shares of Common Stock actually purchased upon the exercise of such rights or
warrants actually exercised.

                          (iv)     If the Company, at any time while shares of
Preferred Stock are outstanding, shall distribute to all holders of Common
Stock (and not to holders of Preferred Stock) evidences of its indebtedness or
assets or rights or warrants to subscribe for or purchase any security
(excluding those referred to in Sections 5(c)(ii) and (iii) above), then in
each such case the Initial Conversion Price at which each share of Preferred
Stock shall thereafter be convertible shall be determined by multiplying the
Initial Conversion Price in effect immediately prior to the record date fixed
for determination of stockholders entitled to receive such distribution by a
fraction of which the denominator shall be the Per Share Market Value of Common
Stock determined as of the record date mentioned above, and of which the
numerator shall be such Per Share Market Value of the Common Stock on such
record date less the then fair market value at such record date of the portion
of such assets or evidence of indebtedness so distributed applicable to one
outstanding share of Common Stock as determined by the Board of Directors in
good faith; provided, however, that if the holders of a majority in interest of
the shares of Preferred Stock dispute such amount, such holders may select a
nationally recognized or major regional investment banking firm or firm of
independent certified public accountants of recognized standing (an
"Appraiser") paid for by the holders of a majority in interest of the shares of
Preferred Stock then outstanding, in which case the fair market value shall be
equal to the average of the determinations by the Board of Directors and such
Appraiser.  In either case the adjustments shall be described in a statement
provided to the holders of Preferred Stock of the portion of assets or
evidences of indebtedness so distributed or such subscription rights applicable
to one share of Common Stock.  Such adjustment shall be made whenever any such
distribution is made and shall become effective immediately after the record
date mentioned above.

                          (v)     All calculations under this Section 5 shall
be made to the nearest cent or the nearest 1/100th of a share, as the case may
be.

                          (vi)    Whenever the Initial Conversion Price is
adjusted pursuant to Section 5(c)(ii),(iii) or (iv), the Company shall promptly
mail to each holder of Preferred Stock, a notice setting forth the Initial
Conversion Price after such adjustment and setting forth a brief statement of
the facts requiring such adjustment.

                          (vii)   In case of any reclassification of the Common
Stock, any consolidation or merger of the Company with or into another
previously unaffiliated person, the sale or transfer of all or substantially
all of the assets of the Company or any compulsory share





                                     -10-
   11
exchange pursuant to which the Common Stock is converted into other securities,
cash or property (each, a "Business Combination"), the holders of the Preferred
Stock then outstanding shall have the right thereafter to, at their option, (A)
convert such shares only into the shares of stock and other securities, cash
and property receivable upon or deemed to be held by holders of Common Stock
following such Business Combination, and the holders of the Preferred Stock
shall be entitled upon such event to receive such amount of securities, cash or
property as the shares of the Common Stock of the Company into which such
shares of Preferred Stock could have been converted immediately prior to such
Business Combination would have been entitled or (B) require the Company to
redeem its shares of Preferred Stock then outstanding at a price per share
equal to the product of (x) the average Per Share Market Value for the five (5)
Trading Days immediately preceding (i) the effective date or the date of the
closing, as the case may be, of the Business Combination triggering such
redemption right or (ii) the date of payment in full by the Company of the
redemption price hereunder, whichever is greater, and (y) the Conversion Ratio
calculated on the date of the closing or the effective date, as the case may
be, of the Business Combination triggering such redemption right, as the case
may be.  The entire redemption price shall be paid in cash, and the terms of
payment of such redemption price shall be subject to the provisions set forth
in Section 6(b).  The terms of any such Business Combination shall include such
terms so as to continue to give to the holder of Preferred Stock the right to
receive the securities, cash or property set forth in this Section 5(c)(vii)
upon any conversion or redemption following such Business Combination upon
terms substantially equivalent to those contained herein.  This provision shall
similarly apply to successive reclassifications, consolidations, mergers,
sales, transfers or share exchanges.

                  (viii)  If:                                              
                                                                              
                  A.     the Company shall declare a dividend (or any other 
                         distribution) on its Common Stock; or  
                                                                              
                  B.     the Company shall declare a special nonrecurring cash
                         dividend on or a redemption of its Common Stock; or 
                                                                             
                  C.     the Company shall authorize the granting to all 
                         holders of the Common Stock rights or warrants to      
                         subscribe for or purchase any shares of capital stock
                         of any class or of any rights; or                
                                                                          
                  D.     the approval of any stockholders of the Company shall
                         be required in connection with any reclassification    
                         of the Common Stock of the Company, any consolidation
                         or merger to which the Company is a party, any sale or
                         transfer of all or substantially all of the assets of
                         the Company, of any compulsory share of exchange 
                         whereby the Common Stock is converted into other 
                         securities, cash or property; or

   12
                       E.     the Company shall authorize the voluntary or 
                              involuntary dissolution, liquidation or winding 
                              up of the affairs of the Company;

then the Company shall cause to be filed at each office or agency maintained
for the purpose of conversion of Preferred Stock, and shall cause to be mailed
to the holders of Preferred Stock at their last addresses as they shall appear
upon the stock books of the Company, at least 30 calendar days prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution, redemption, rights or warrants, or if a record is not to be
taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distributions, redemption, rights or warrants are to
be determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, 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, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange; provided, however,
that the failure to mail such notice or any defect therein or in the mailing
thereof shall not affect the validity of the corporate action required to be
specified in such notice.  Holders are entitled to convert shares of Preferred
Stock during the 30-day period commencing the date of such notice to the
effective date of the event triggering such notice.

                 (d)      The Company covenants that it will at all times
reserve and keep available out of its authorized and unissued Common Stock
solely for the purpose of issuance upon conversion of Preferred Stock and
payment of dividends on Preferred Stock, each as herein provided, free from
preemptive rights or any other actual contingent purchase rights of persons
other than the holders of Preferred Stock, not less than such number of shares
of Common Stock as shall (subject to any additional requirements of the Company
as to reservation of such shares set forth in the Purchase Agreement) be
issuable (taking into account the adjustments and restrictions of Section 5(c))
upon the conversion of all outstanding shares of Preferred Stock and payment of
dividends hereunder.  The Company covenants that all shares of Common Stock
that shall be so issuable shall, upon issue, be duly and validly authorized,
issued and fully paid, nonassessable and freely tradeable.

                 (e)      Upon a conversion hereunder the Company shall not be
required to issue stock certificates representing fractions of shares of Common
Stock, but may if otherwise permitted, make a cash payment in respect of any
final fraction of a share based on the Per Share Market Value at such time.  If
the Company elects not, or is unable, to make such a cash payment, the holder
of a share of Preferred Stock shall be entitled to receive, in lieu of the
final fraction of a share, one whole share of Common Stock.

                 (f)      The issuance of certificates for shares of Common
Stock on conversion of Preferred Stock shall be made without charge to the
holders thereof for any documentary stamp or similar taxes that may be payable
in respect of the issue or delivery of such certificate, provided that the
Company shall not be required to pay any tax that may be payable in respect





                                     -12-
   13
of any transfer involved in the issuance and delivery of any such certificate
upon conversion in a name other than that of the holder of such shares of
Preferred Stock so converted and the Company shall not be required to issue or
deliver such certificates unless or until the person or persons requesting the
issuance thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been
paid.

                 (g)      Shares of Preferred Stock converted into Common Stock
shall be canceled and shall have the status of authorized but unissued shares
of preferred stock of the Company.

                 (h)      Any and all notices or other communications or
deliveries to be provided by the holders of the Preferred Stock hereunder,
including, without limitation, any Conversion Notice, shall be in writing and
delivered personally, by facsimile, or by a nationally recognized overnight
courier service to the attention of the Chief Financial Officer of the Company
at the facsimile telephone number or address of the principal place of business
of the Company as set forth in the Purchase Agreement.  Any and all notices or
other communications or deliveries to be provided by the Company hereunder
shall be in writing and delivered personally, by facsimile, or by a nationally
recognized overnight courier service addressed to each holder of Preferred
Stock at the facsimile telephone number or address of such holder appearing on
the books of the Company, or if no such facsimile telephone number or address
appears, at the principal place of business of the holder.  Any notice or other
communication or deliveries hereunder shall be deemed delivered (i) upon
receipt, when delivered personally, (ii) when sent by facsimile, upon receipt
if received on a Business Day prior to 5:00 p.m. (Eastern Time), or on the
first Business Day following such receipt if received on a Business Day after
5:00 p.m. (Eastern Time) or (iii) the Business Day following the date of
depositing with a nationally recognized overnight courier service.

                 Section 6.       Redemption.  (a)  The Company shall have the
right, exercisable at any time upon 5 Trading Days' notice to the holders of
the Preferred Stock given at any time on or after the third anniversary of the
Original Issue Date to redeem all or any portion of the shares of Preferred
Stock which have not previously been converted or redeemed, at a price per
share equal to the product of (x) the average Per Share Market Value for the
five (5) Trading Days immediately preceding (i) the date of the redemption
notice referenced above, (ii) the date of payment in full by the Company of the
redemption price hereunder, or (iii) if payment is not made by the fifth
Trading Day after the Company's redemption notice, such fifth Trading Day
whichever is greater, and (y) the Conversion Ratio calculated on the date of
such redemption notice.  The entire redemption price shall be paid in cash.
Holders of Preferred Stock may convert any shares of Preferred Stock, including
shares subject to a redemption notice given under this Section, during the
period from the date of such redemption notice through the date on which the
redemption price for such Preferred Stock is paid by the Company and the
Company shall honor all properly tendered Conversion Notices during such
period.  Any redemption notice under this Section 6 shall indicate the number
of shares of Preferred Stock to be redeemed and the date (subject to the terms
hereof) on which such redemption is to occur.  The holders of the Preferred
Stock to be redeemed shall tender by overnight mail, shares of Preferred Stock
subject to such redemption on the date prior to the redemption date.  If the





                                     -13-
   14
Company intends to redeem less than all of the then outstanding Preferred
Stock, it shall do so on a pro rata basis among such holders in accordance with
this Section.  If any portion of the applicable redemption price under this
Section 6 shall not be paid by the Company within seven days after the date
due, interest shall accrue thereon at the rate of 15% per annum until the
redemption price plus all such interest is paid in full (which amount shall be
paid as liquidated damages and not as a penalty).  In addition, if any portion
of such redemption price remains unpaid for more than seven days after the date
due, the holder of the Preferred Stock subject to such redemption may elect, by
written notice to the Company given within 30 days after the date due, to
either (i) demand conversion in accordance with the formula and the time frame
therefor set forth in Section 5 of all of the shares of Preferred Stock for
which such redemption price, plus accrued liquidated damages thereof, has not
been paid in full (the "Unpaid Redemption Shares"), in which event the Per
Share Market Price for such shares shall be the lower of the Per Share Market
Price calculated on the date such redemption price was originally due and the
Per Share Market Price as of the holder's written demand for conversion, or
(ii) invalidate ab initio such redemption, notwithstanding anything herein
contained to the contrary.  If the holder elects option (i) above, the Company
shall within three (3) Trading Days of its receipt of such election deliver to
the holder the shares of Common Stock issuable upon conversion of the Unpaid
Redemption Shares subject to such holder conversion demand and otherwise
perform its obligations hereunder with respect thereto; or, if the Holder
elects option (ii) above, the Company shall promptly, and in any event not
later than three (3) Trading Days from receipt of holder's notice of such
election, return to the holder all of the Unpaid Redemption Shares.

                 (b)      The Company shall have the right, exercisable within
20 days after the issuance of a press release disclosing the execution by the
Company of a definitive agreement for the sale of all or substantially all of
its assets to another previously unaffiliated Person or the merger or
consolidation of the Company with or into another previously unaffiliated
Person pursuant to which a Person acquires voting securities of the Company
which, after giving effect to such acquisition, results in such Person
beneficially owning in excess of 50% of the issued and outstanding voting
securities of the Company or the surviving entity or pursuant to which one-half
of the members of the Board of Directors or the board of directors of the
surviving entity is replaced, to provide an irrevocable notice of redemption to
the holders of the Preferred Stock as to all, but not less than all, of the
then outstanding shares of Preferred Stock.  The aggregate redemption price
shall be paid in cash on the closing date for such Business Combination.  The
redemption price per share shall equal the product of (x) the average Per Share
Market Value for the five (5) Trading Days immediately preceding the closing
date for the Business Combination triggering such redemption and (y) the
Conversion Ratio calculated on the date of such redemption notice.  The
definitive merger or purchase agreement for such Business Combination shall
include a provision by which the Company covenants to pay the redemption price
under this Section on the closing date therefor.

                              NOTICE OF CONVERSION


(To be Executed by the Registered Holder
