                    CERTIFICATE OF DESIGNATIONS, PREFERENCES
               AND RIGHTS OF SERIES C CONVERTIBLE PREFERRED STOCK
                                       OF
                                 JTS CORPORATION


         JTS Corporation (the "COMPANY"), a corporation organized and existing
under the General Corporation Law of the State of Delaware, does hereby certify
that, pursuant to authority conferred upon the Board of Directors of the Company
by the Certificate of Incorporation, as amended, of the Company, and pursuant to
Section 151 of the General Corporation Law of the State of Delaware, the Board
of Directors of the Company at a meeting duly held, adopted resolutions (i)
authorizing a series of the Company's previously authorized preferred stock,
$.001 par value per share, and (ii) providing for the designations, preferences
and relative, participating, optional or other rights, and the qualifications,
limitations or restrictions thereof, of twenty-five thousand (25,000) shares of
Series C Convertible Preferred Stock of the Company, as follows:

                  RESOLVED, that the Company is authorized to issue 25,000
         shares of Series C Convertible Preferred Stock (the "SERIES C PREFERRED
         SHARES"), $.001 par value per share, which shall have the following
         powers, designations, preferences and other special rights:

                  (1) Dividends. The Series C Preferred Shares shall not bear
         any dividends.

                  (2) Holder's Conversion of Series C Preferred Shares. A holder
         of Series C Preferred Shares shall have the right, at such holder's
         option, to convert the Series C Preferred Shares into shares of the
         Company's common stock, $.001 par value per share (the "COMMON STOCK"),
         on the following terms and conditions:

                      (a) Conversion Right. At any time or times on or after the
         earlier of (i) the date the Registration Statement (as defined below)
         is declared effective by the United States Securities and Exchange
         Commission (the "SEC") and (ii) eighty (80) days after the initial date
         of issuance of the Series C Preferred Shares (the "SCHEDULED EFFECTIVE
         DATE"), any holder of Series C Preferred Shares shall be entitled to
         convert any


   2
         whole number of Series C Preferred Shares into (x) fully paid and
         nonassessable shares (rounded to the nearest whole share in accordance
         with Section 2(g) below) of Common Stock, at the Conversion Rate (as
         defined below) plus (y) an amount per Series C Preferred Share being
         converted (the"ADDITIONAL AMOUNT") equal to the product of
         (.05)(N/365)(1,000), which Additional Amount may be paid, at the option
         of the Company either (I) in cash or (II) in fully paid and
         nonassessable shares of Common Stock (rounded to the nearest whole
         share in accordance with Section 2(g) below) valued at the Average
         Market Price (as defined below) for such Common Stock for the five (5)
         consecutive trading days immediately preceding the Conversion Date (as
         defined below); provided, however, that in no event shall any holder be
         entitled to convert Series C Preferred Shares in excess of that number
         of Series C Preferred Shares which, upon giving effect to such
         conversion, would cause the aggregate number of shares of Common Stock
         beneficially owned by the holder and its affiliates to exceed 4.9% of
         the outstanding shares of the Common Stock following such conversion.
         For purposes of the foregoing proviso, the aggregate number of shares
         of Common Stock beneficially owned by the holder and its affiliates
         shall include the number of shares of Common Stock issuable upon
         conversion of the Series C Preferred Shares with respect to which the
         determination of such proviso is being made, but shall exclude the
         number of shares of Common Stock which would be issuable upon
         conversion of the remaining, nonconverted Series C Preferred Shares
         beneficially owned by the holder and its affiliates. Except as set
         forth in the preceding sentence, for purposes of this paragraph,
         beneficial ownership shall be calculated in accordance with Section
         13(d) of the Securities Exchange Act of 1934, as amended.

                      (b) Conversion Rate. The number of shares of Common
         Stock issuable upon conversion of each of the Series C Preferred Shares
         pursuant to Section (2)(a)(x) above shall equal the quotient obtained
         by dividing (i) 1,000 by (ii) the Conversion Price (the "CONVERSION
         RATE"). For purposes of this Certificate of Designations, the following
         terms shall have the following meanings:

                          (i)  "CONVERSION PRICE" means, as of any Conversion
         Date (as defined below), the lower of the Fixed Conversion Price and
         the Floating Conversion Price, each in effect as of such date and
         subject to adjustment as provided herein;

                          (ii)  "FIXED CONVERSION PRICE" means the lower of
         (A) $3.6125 and (B) the Average Market Price for the Common Stock for
         the five (5) consecutive trading days immediately preceding the date on
         which the Registration Statement is declared effective by the SEC,
         subject to adjustment as provided herein;

                          (iii) "FLOATING CONVERSION PRICE" means, as of any 
         date of determination, the amount obtained by multiplying the
         Conversion Percentage in effect as of such date by the Average Market
         Price for the Common Stock for the five (5) consecutive trading days
         immediately preceding such date;

                          (iv)  "CONVERSION PERCENTAGE" means eighty-five 
         percent (85%), subject to adjustment as provided herein;


                                       -2-

   3
                          (v)   "AVERAGE MARKET PRICE" means, with respect to 
         any security for any period, that price which shall be computed as the
         arithmetic average of the Lowest Sale Prices (as defined below) for
         such security for each trading day in such period (all as appropriately
         adjusted for any stock dividend, stock split, pro rata below market
         price rights offering or other similar transaction during such period);

                          (vi)  "LOWEST SALE PRICE" means, for any security as 
         of any date, the lowest sale price on The American Stock Exchange, Inc.
         ("AMEX") as reported by Bloomberg Financial Markets ("BLOOMBERG"), or,
         if AMEX is not the principal trading market for such security, the
         lowest sale price of such security on the principal securities exchange
         or trading market where such security is listed or traded as reported
         by Bloomberg, or if the foregoing do not apply, the lowest sale price
         of such security in the over-the-counter market on the electronic
         bulletin board for such security as reported by Bloomberg, or, if no
         sale price is reported for such security by Bloomberg, the average of
         the bid prices of any market makers for such security as reported in
         the "pink sheets" by the National Quotation Bureau, Inc. If the Lowest
         Sale Price cannot be calculated for such security on such date on any
         of the foregoing bases, the Lowest Sale Price of such security on such
         date shall be the fair market value as reasonably determined in good
         faith by the Board of Directors of the Company; and

                          (vii) "N" means the number of days from, but 
         excluding, the date that, in connection with the consummation of the
         initial purchase by the holder of Series C Preferred Shares from the
         Company, the Company first had in its possession funds representing
         full payment for the Series C Preferred Shares for which conversion is
         being elected, through and including the Conversion Date for the Series
         C Preferred Shares for which conversion is being elected.

                      (c) Adjustment to Conversion Price - Registration
         Statement. If the registration statement (the "REGISTRATION STATEMENT")
         covering the resale of the shares of Common Stock issuable upon
         conversion of the Series C Preferred Shares and required to be filed by
         the Company pursuant to the Registration Rights Agreement between the
         Company and the initial holders of the Series C Preferred Shares (THE
         "REGISTRATION RIGHTS AGREEMENT") is not declared effective by the SEC
         on or before the Scheduled Effective Date, or, if after the
         Registration Statement has been declared effective by the SEC, sales
         cannot be made pursuant to the Registration Statement (whether because
         of a failure to keep the Registration Statement effective, to disclose
         such information as is necessary for sales to be made pursuant to the
         Registration Statement, to register sufficient shares of Common Stock
         or otherwise), then, as partial relief for the damages to any holder by
         reason of any such delay in or reduction of its ability to sell the
         underlying shares of Common Stock (which remedy shall not be exclusive
         of any other remedies available at law or in equity), the Conversion
         Percentage and the Fixed Conversion Price shall be adjusted as follows:

                          (i)  Conversion Percentage.  Except as provided in
         Section 3(a) and Section 3(f) of the Registation Rights Agreement, the
         Conversion Percentage in effect at such time shall be reduced by a
         number of percentage points equal to the


                                       -3-

   4
         product of (A) two and one-half (2.5) and (B) the sum of (I) the number
         of months (prorated for partial months) after the Scheduled Effective
         Date and prior to the date that the relevant Registration Statement is
         declared effective by the SEC and (II) the number of months (prorated
         for partial months) that sales cannot be made pursuant to the
         Registration Statement after the Registration Statement has been
         declared effective; provided, however, that the maximum aggregate
         reduction in the Conversion Percentage due to this Section 2(c)(i)
         shall be fifteen (15) percentage points. (For example, if the
         Registration Statement becomes effective one and one-half (1 1/2)
         months after the Scheduled Effective Date, the Conversion Percentage
         would be eighty-one and one-fourth percent (81.25%) until any
         subsequent adjustment; if thereafter sales could not be made pursuant
         to the Registration Statement for a period of two (2) additional
         months, the Conversion Percentage would then be seventy-six and
         one-fourth percent (76.25%)); and

                          (ii)  Fixed Conversion Price.  The Fixed Conversion 
         Price in effect at such time shall be reduced by an amount equal to the
         product of (A) nine-hundred and three ten-thousandths (.0903) and (B)
         the sum of (I) the number of months (prorated for partial months) after
         the Scheduled Effective Date and prior to the date that the
         Registration Statement is declared effective by the SEC and (II) the
         number of months (prorated for partial months) that sales cannot be
         made pursuant to the Registration Statement after the Registration
         Statement has been declared effective; provided, however, that the
         maximum aggregate reduction in the Fixed Conversion Price pursuant to
         this section 2(c)(ii) shall be an amount equal to 15% of the Fixed
         Conversion Price in effect at such time. (For example, assuming the
         Fixed Conversion Price is $3.6125, if the Registration Statement
         becomes effective one and one-half (1 1/2) months after the Scheduled
         Effective Date, the Fixed Conversion Price would be $3.4771 until any
         subsequent adjustment; if thereafter sales could not be made pursuant
         to the Registration Statement for a period of two (2) additional
         months, the Fixed Conversion Price would then be $3.2965).

                      (d) Adjustment to Conversion Price -- Dilution and
         Other Events. In order to prevent dilution of the rights granted under
         this Certificate of Designations, the Conversion Price will be subject
         to adjustment from time to time as provided in this Section 2(d).

                          (i)  Adjustment of Fixed Conversion Price upon 
         Subdivision or Combination of Common Stock. If the Company at any time
         subdivides (by any stock split, stock dividend, recapitalization, pro
         rata below market price rights offering or otherwise) one or more
         classes of its outstanding shares of Common Stock into a greater number
         of shares, the Fixed Conversion Price in effect immediately prior to
         such subdivision will be proportionately reduced. If the Company at any
         time combines (by combination, reverse stock split or otherwise) one or
         more classes of its outstanding shares of Common Stock into a smaller
         number of shares, the Fixed Conversion Price in effect immediately
         prior to such combination will be proportionately increased.

                          (ii)  Reorganization, Reclassification, Consolidation,
         Merger or Sale. Any recapitalization, reorganization, reclassification,
         consolidation, merger, sale


                                       -4-

   5
         of all or substantially all of the Company's assets to another Person
         (as defined below) or other transaction which is effected in such a way
         that holders of Common Stock are entitled to receive (either directly
         or upon subsequent liquidation) stock, securities or assets with
         respect to or in exchange for Common Stock is referred to herein as
         "ORGANIC CHANGE." Prior to the consummation of any Organic Change, the
         Company will make appropriate provision (in form and substance
         satisfactory to the holders of a majority of the Series C Preferred
         Shares then outstanding) to insure that each of the holders of the
         Series C Preferred Shares will thereafter have the right to acquire and
         receive in lieu of or addition to (as the case may be) the shares of
         Common Stock immediately theretofore acquirable and receivable upon the
         conversion of such holder's Series C Preferred Shares, such shares of
         stock, securities or assets as may be issued or payable with respect to
         or in exchange for the number of shares of Common Stock immediately
         theretofore acquirable and receivable upon the conversion of such
         holder's Series C Preferred Shares had such Organic Change not taken
         place. In any such case, the Company will make appropriate provision
         (in form and substance satisfactory to the holders of a majority of the
         Series C Preferred Shares then outstanding) with respect to such
         holders' rights and interests to insure that the provisions of this
         Section 2(d) and Section 2(e) below will thereafter be applicable to
         the Series C Preferred Shares (including, in the case of any such
         consolidation, merger or sale in which the successor entity or
         purchasing entity is other than the Company, an immediate adjustment of
         the Fixed Conversion Price to the value for the Common Stock reflected
         by the terms of such consolidation, merger or sale, if the value so
         reflected is less than the Fixed Conversion Price in effect immediately
         prior to such consolidation, merger or sale). The Company will not
         effect any such consolidation, merger or sale, unless prior to the
         consummation thereof, the successor entity (if other than the Company)
         resulting from consolidation or merger or the entity purchasing such
         assets assumes, by written instrument (in form and substance
         satisfactory to the holders of a majority of the Series C Preferred
         Shares then outstanding), the obligation to deliver to each holder of
         Series C Preferred Shares such shares of stock, securities or assets
         as, in accordance with the foregoing provisions, such holder may be
         entitled to acquire. For purposes of this Agreement, "PERSON" shall
         mean an individual, a limited liability company, a partnership, a joint
         venture, a corporation, a trust, an unincorporated organization and a
         government or any department or agency thereof.

                          (iii)  Notices.

                                (A)   Immediately upon any adjustment of the
         Fixed Conversion Price, the Company will give written notice thereof to
         each holder of Series C Preferred Shares, setting forth in reasonable
         detail and certifying the calculation of such adjustment.

                                (B)   The Company will give written notice to
         each holder of Series C Preferred Shares at least twenty (20) days
         prior to the date on which the Company closes its books or takes a
         record (I) with respect to any dividend or distribution upon the Common
         Stock, (II) with respect to any pro rata subscription offer


                                       -5-

   6
         to holders of Common Stock or (III) for determining rights to vote with
         respect to any Organic Change, dissolution or liquidation.

                                 (C)   The Company will also give written notice
         to each holder of Series C Preferred Shares at least twenty (20) days
         prior to the date on which any Organic Change, dissolution or
         liquidation will take place.

                      (e) Purchase Rights. In addition to any adjustments of the
         Conversion Price pursuant to Section 2(d) above, if at any time the
         Company grants, issues or sells any rights or options to subscribe for
         or to purchase Common Stock, any stock or other securities convertible
         into or exchangeable for Common Stock or any rights to purchase stock,
         warrants, securities or other property, in each case, pro rata to the
         record holders of any class of Common Stock (the "PURCHASE RIGHTS"),
         then the holders of Series C Preferred Shares will be entitled to
         acquire, upon the terms applicable to such Purchase Rights, the
         aggregate Purchase Rights which such holder could have acquired if such
         holder had held the number of shares of Common Stock acquirable upon
         complete conversion of the Series C Preferred Shares immediately before
         the date on which a record is taken for the grant, issuance or sale of
         such Purchase Rights, or, if no such record is taken, the date as of
         which the record holders of Common Stock are to be determined for the
         grant, issue or sale of such Purchase Rights.

                      (f) Mechanics of Conversion.  Subject to the Company's
         inability to fully satisfy its obligations under a Conversion Notice
         (as defined below) as provided for in Section 5 below:

                          (i)  Holder's Delivery Requirements.  To convert
         Series C Preferred Shares into full shares of Common Stock on any date
         (the "CONVERSION DATE"), the holder thereof shall (A) deliver or
         transmit by facsimile, for receipt on or prior to 11:59 p.m., Pacific
         Standard Time on such date, a copy of a fully executed notice of
         conversion in the form attached hereto as Exhibit I (the "CONVERSION
         NOTICE"), to the Company or its designated transfer agent (the
         "TRANSFER AGENT"), and (B) surrender to a common carrier for delivery
         to the Company or the Transfer Agent as soon as practicable following
         such date, the original certificates representing the Series C
         Preferred Shares being converted (or an indemnification undertaking
         with respect to such shares in the case of their loss, theft or
         destruction) (the "PREFERRED STOCK CERTIFICATES") and the originally
         executed Conversion Notice.

                          (ii) Company's Response.  Upon receipt by the Company
         of a facsimile copy of a Conversion Notice, the Company shall
         immediately send, via facsimile, a confirmation of receipt of such
         Conversion Notice to such holder. Upon receipt by the Company or the
         Transfer Agent of the Preferred Stock Certificates to be converted
         pursuant to a Conversion Notice, together with the originally executed
         Conversion Notice, the Company or the Transfer Agent (as applicable)
         shall, on the next business day following the date of receipt (or the
         second business day following the date of receipt if received after
         11:00 a.m. local time of the Company or Transfer Agent, as applicable),
         (A) (I) issue and surrender to a common carrier for overnight delivery
         to the


                                       -6-

   7
         address as specified in the Conversion Notice, a certificate,
         registered in the name of the holder or its designee, for the number of
         shares of Common Stock to which the holder shall be entitled, including
         the number of shares of Common Stock constituting the Additional Amount
         if the Company elects to pay the Additional Amount in Common Stock or
         (II) credit such aggregate number of shares of Common Stock to which
         the holder shall be entitled to the holder's or its designee's balance
         account with the Depository Trust Corporation, and (B) issue and
         surrender to a common carrier for overnight delivery to the address as
         specified in the Conversion Notice, a check drawn on an account of the
         Company and payable to the order of the holder or its designee in an
         amount equal to the Additional Amount, if the Company elects to pay the
         Additional Amount in cash.

                          (iii) Dispute Resolution.  In the case of a dispute as
         to the determination of the Lowest Sale Price or the arithmetic
         calculation of the Conversion Rate or the Additional Amount, the
         Company shall promptly issue to the holder the number of shares of
         Common Stock and cash, if applicable, that is not disputed and shall
         submit the disputed determinations or arithmetic calculations to the
         holder via facsimile within one (1) day of receipt of such holder's
         Conversion Notice. If such holder and the Company are unable to agree
         upon the determination of the Lowest Sale Price or arithmetic
         calculation of the Conversion Rate or the Additional Amount within one
         (1) day of such disputed determination or arithmetic calculation being
         submitted to the holder, then the Company shall immediately submit via
         facsimile (A) the disputed determination of the Lowest Sale Price to an
         independent, reputable investment bank or (B) the disputed arithmetic
         calculation of the Conversion Rate or the Additional Amount to its
         independent, outside accountant. The Company shall cause the investment
         bank or the accountant, as the case may be, to perform the
         determinations or calculations and notify the Company and the holder of
         the results no later than forty-eight (48) hours from the time it
         receives the disputed determinations or calculations. Such investment
         bank's or accountant's determination or calculation, as the case may
         be, shall be binding upon all parties absent manifest error.

                          (iv)  Record Holder.  The person or persons entitled
         to receive the shares of Common Stock issuable upon a conversion of
         Series C Preferred Shares shall be treated for all purposes as the
         record holder or holders of such shares of Common Stock on the
         Conversion Date.

                          (v)   Company's Failure to Timely Convert.  If the
         Company shall fail to issue to a holder on a timely basis as described
         in this Section 2(f), a certificate for the number of shares of Common
         Stock to which such holder is entitled upon such holder's conversion of
         Series C Preferred Shares, including shares of Common Stock which
         constitute the Additional Amount, if the Company elects to pay the
         Additional Amount in Common Stock, in addition to all other available
         remedies which such holder may pursue, the Company shall pay damages to
         such holder on each date such conversion is not timely effected in an
         amount equal to 5% of the product of (A) the number of shares of Common
         Stock not issued to the holder on a timely basis and to which such
         holder is entitled and (B) the Closing Price (as defined below) of the


                                       -7-

   8
         Common Stock on the last possible date which the Company could have
         issued such Common Stock to such holder without violating this Section
         2(f). If the Company elects to pay the Additional Amount in cash, and
         fails to pay such Additional Amount on a timely basis as described in
         Section 2(f)(ii) above, such unpaid amount shall bear interest at the
         rate of 2.5% per month until paid in full.

                      (g) Fractional Shares. The Company shall not issue  any 
         fraction of a share of Common Stock upon any conversion. All shares of
         Common Stock (including fractions thereof) issuable upon conversion of
         more than one Series C Preferred Share by a holder thereof (including
         shares of Common Stock issuable in connection with the payment of an
         Additional Amount, if the Company elects to pay such Additional Amount
         in Common Stock) shall be aggregated for purposes of determining
         whether the conversion would result in the issuance of a fraction of a
         share of Common Stock. If, after the aforementioned aggregation, the
         issuance would result in the issuance of a fraction of a share of
         Common Stock, the Company shall round such fraction of a share of
         Common Stock up or down to the nearest whole share.

                      (h) Taxes. The Company shall pay any and all taxes  which 
         may be imposed upon it with respect to the issuance and delivery of
         Common Stock upon the conversion of the Series C Preferred Shares.

                  (3) Redemption at Option of Holders.

                      (a) Redemption Option Upon Major Transaction. In
         addition to all other rights of the holders of Series C Preferred
         Shares contained herein, after a Major Transaction (as defined below),
         the holders of Series C Preferred Shares shall have the right, at the
         option of the holders of at least two-thirds (2/3) of the Series C
         Preferred Shares then outstanding, to require the Company to redeem all
         of the Series C Preferred Shares then outstanding in exchange for
         consideration (the "REDEMPTION CONSIDERATION") per Series C Preferred
         Share equal to the greater of (i) the number of shares of stock or
         securities or cash or property of the Company, or of the entity
         resulting from such consolidation, merger or tender or exchange offer
         (the "MAJOR TRANSACTION CONSIDERATION"), to which a holder of the
         number of shares of Common Stock delivered upon conversion of such
         Series C Preferred Share would have been entitled upon such Major
         Transaction (x) had the holder of such Series C Preferred Share
         exercised its right of conversion on the date of the public
         announcement of such Major Transaction and (y) had such Common Stock
         been issued and outstanding and had such holder been the holder of
         record of such Common Stock at the time of such Major Transaction and
         (ii) an amount of Major Transaction Consideration to which a holder of
         the number of shares of Common Stock equal to (A) the product of 1.1765
         and the Liquidation Value of such Series C Preferred Share, divided by
         (B) the Lowest Sale Price of the Common Stock on the date prior to the
         consummation of the Major Transaction would have been entitled upon
         such Major Transaction had such Common Stock been issued and
         outstanding and had such holder been the holder of record of such
         Common Stock at the time of such Major Transaction, and in either case
         the Company shall make


                                       -8-

   9



         lawful provision therefor as a part of such consolidation, merger or
         tender or exchange offer.

                      (b) Redemption Option Upon Triggering Event. In addition
         to all other rights of the holders of Series C Preferred Shares
         contained herein, after a Triggering Event (as defined below), the
         holders of Series C Preferred Shares shall have the right, at the
         option of the holders of at least two-thirds (2/3) of the Series C
         Preferred Shares then outstanding, to require the Company to redeem all
         of the Series C Preferred Shares then outstanding at a price per Series
         C Preferred Share in cash (the "OPTIONAL REDEMPTION PRICE") equal to
         the greater of (i) 117.65% of the Liquidation Value of such share and
         (ii) the price calculated in accordance with the Redemption Rate
         calculated as of the date immediately preceding such Triggering Event
         on which the exchange or market on which the Common Stock is traded is
         open.

                      (c) "Redemption Rate". The "REDEMPTION RATE" shall, as of 
         any date of determination, be equal to the sum of (i) the product
         obtained by multiplying (A) the Conversion Rate in effect as of such
         date as calculated pursuant to Section 2(b) by (B) the Closing Price of
         the Common Stock on such date, and (ii) an amount equal to the product
         of (.05)(N/365)(1,000).

                      (d) "Closing Price". "CLOSING PRICE" means, for any
         security as of any date, the last closing price on AMEX as reported by
         Bloomberg, or, if AMEX is not the principal trading market for such
         security, the last closing price of such security on the principal
         securities exchange or trading market where such security is listed or
         traded as reported by Bloomberg, or if the foregoing do not apply, the
         closing price of such security in the over-the-counter market on the
         electronic bulletin board for such security as reported by Bloomberg,
         or, if no closing price is reported for such security by Bloomberg, the
         average of the ask prices of any market makers for such security as
         reported in the "pink sheets" by the National Quotation Bureau, Inc. If
         the Closing Price cannot be calculated for such security on such date
         on any of the foregoing bases, the Closing Price of such security on
         such date shall be the fair market value as reasonably determined in
         good faith by the Board of Directors of the Company (all as
         appropriately adjusted for any stock dividend, stock, split or other
         similar transaction during such period).

                      (e) "Major Transaction".  A "MAJOR TRANSACTION" shall
         be deemed to have occurred at such time as any of the following events:

                          (i)   the consolidation or merger of the Company with
         or into another Person (other than pursuant to a migratory merger
         effected solely for the purpose of changing the jurisdiction of
         incorporation of the Company);

                          (ii)  the sale or transfer of substantially all of the
         Company's assets; or



                                       -9-

   10



                          (iii) a purchase, tender or exchange offer made to and
         accepted by the holders of more than 10% of the outstanding shares of
         Common Stock.

                      (f) "Triggering Event".  A "TRIGGERING EVENT" shall be
         deemed to have occurred at such time as any of the following events:

                          (i)   the failure of the Registration Statement to be
         declared effective by the SEC on or prior to the date that is sixty
         (60) days after the Scheduled Effective Date;

                          (ii)  either (A) the failure of the Registration 
         Statement to be effective or to cover the resale of all of the shares
         of Common Stock issued or issuable upon conversion of the Series C
         Preferred Shares or (B) notice from the Company that Common Stock
         issued or issuable upon conversion of the Shares C Preferred Shares
         cannot be sold under the Registration Statement, for any period of
         sixty (60) consecutive days after the date that is sixty (60) days
         after the Scheduled Effective Date (provided that for purposes of
         determining the Closing Price under Section 3(c) above, the Triggering
         Event shall be deemed to have occurred on the first day of such 60-day
         period);

                          (iii) David T. Mitchell ceases to be a director or 
         officer of the Company prior to August 1, 1997 for any reason other
         than death or "disability"; provided that for purposes of this
         Certificate of Designations, David T. Mitchell shall be deemed to have
         a "disability" if he is unable to perform, by reason of physical or
         mental incapacity, his duties or obligations as a director or officer
         of the Company for any thirty (30) consecutive day period;

                          (iv)  the failure of the Common Stock to be listed on 
         AMEX, the Nasdaq National Market or The New York Stock Exchange, Inc.
         for a period of seven (7) consecutive days (provided that for purposes
         of determining the Closing Price under Section 3(c) above, the
         Triggering Event shall be deemed to have occurred on the first day of
         such seven-day period and provided further that such failure shall not
         constitute a Triggering Event if caused by holders of Series C
         Preferred Shares pursuant to Section 3(i) below); or

                          (v)   the Company's notice to any holder of Series C
         Preferred Shares, including by way of public announcement, at any time,
         of its intention not to comply with proper requests for conversion of
         any Series C Preferred Shares into shares of Common Stock, including
         due to any of the reasons set forth in Section 5(a) below.

                      (g) Mechanics of Redemption at Option of Buyer Upon
         Major Transaction. No sooner than fifteen (15) days nor later than ten
         (10) days prior to the consummation of a Major Transaction, but not
         prior to the public announcement of such Major Transaction, the Company
         shall deliver written notice thereof via facsimile and overnight
         courier ("NOTICE OF MAJOR TRANSACTION") to each holder of Series C
         Preferred Shares. At any time after receipt of a Notice of Major
         Transaction, the holders of at


                                      -10-

   11
         least two-thirds (2/3) of the Series C Preferred Shares then
         outstanding may require the Company to redeem all of the holder's
         Series C Preferred Shares then outstanding by delivering written notice
         thereof via facsimile and overnight courier ("NOTICE OF REDEMPTION AT
         OPTION OF BUYER UPON MAJOR TRANSACTION") to the Company, which Notice
         of Redemption at Option of Buyer Upon Major Transaction shall indicate
         (i) the number of Series C Preferred Shares that such holders are
         voting in favor of redemption and (ii) the applicable Redemption
         Consideration, as calculated pursuant to Section 3(a) above.

                      (h) Mechanics of Redemption at Option of Buyer Upon
         Triggering Event. Within one (1) day after the occurrence of a
         Triggering Event, the Company shall deliver written notice thereof via
         facsimile and overnight courier ("NOTICE OF TRIGGERING EVENT") to each
         holder of Series C Preferred Shares. At any time after receipt of a
         Notice of Triggering Event, the holders of at least two-thirds (2/3) of
         the Series C Preferred Shares then outstanding may require the Company
         to redeem all of the Series C Preferred Shares by delivering written
         notice thereof via facsimile and overnight courier ("NOTICE OF
         REDEMPTION AT OPTION OF BUYER UPON TRIGGERING EVENT") to the Company,
         which Notice of Redemption at Option of Buyer Upon Triggering Event
         shall indicate (i) the number of Series C Preferred Shares that such
         holders are voting in favor of redemption and (ii) the applicable
         Optional Redemption Price, as calculated pursuant to Section 3(b)
         above.

                      (i) Payment of Redemption Price. Upon the Company's
         receipt of a Notice(s) of Redemption at Option of Buyer Upon Major
         Transaction or a Notice(s) of Redemption at Option of Buyer Upon
         Triggering Event, as the case may be, from the holders of at least
         two-thirds (2/3) of the Series C Preferred Shares then outstanding, the
         Company shall immediately notify each holder by facsimile of the
         Company's receipt of such requisite notices necessary to affect a
         redemption and each holder of Series C Preferred Shares shall
         thereafter promptly send such holder's Preferred Stock Certificates to
         be redeemed to the Company or its Transfer Agent. The Company shall
         deliver the applicable Redemption Consideration or Optional Redemption
         Price, as the case may be, to such holder within thirty (30) days after
         the Company's receipt of the requisite notices required to affect a
         redemption; provided that a holder's Preferred Stock Certificates shall
         have been so delivered to the Company or its Transfer Agent; provided
         further that if the Company is unable to redeem all of the Series C
         Preferred Shares, the Company shall redeem an amount from each holder
         of Series C Preferred Shares equal to such holder's pro-rata amount
         (based on the number of Series C Preferred Shares held by such holder
         relative to the number of Series C Preferred Shares outstanding) of all
         Series C Preferred Shares being redeemed. If the Company shall fail to
         redeem all of the Series C Preferred Shares submitted for redemption
         (other than pursuant to a dispute as to the determination of the
         Closing Price or the arithmetic calculation of the Redemption Rate),
         the applicable Redemption Consideration or Optional Redemption Price
         payable in respect of such unredeemed Series C Preferred Shares shall
         bear interest at the rate of 2.5% per month (prorated for partial
         months) until paid in full. Until the Company pays such unpaid
         applicable Redemption Consideration or Optional Redemption Price in
         full to each holder, holders of at least two-thirds (2/3) of the Series
         C Preferred Shares then


                                      -11-

   12
         outstanding, including shares of Series C Preferred Shares submitted
         for redemption pursuant to this Section 3 and for which the applicable
         Redemption Consideration or Optional Redemption Price has not been
         paid, shall have the option (the "VOID OPTIONAL REDEMPTION OPTION") to,
         in lieu of redemption, require the Company to promptly return to each
         holder all of the Series C Preferred Shares that were submitted for
         redemption by such holder under this Section 3 and for which the
         applicable Redemption Consideration or Optional Redemption Price has
         not been paid, by sending written notice thereof to the Company via
         facsimile (the "VOID OPTIONAL REDEMPTION NOTICE"). Upon the Company's
         receipt of such Void Optional Redemption Notice(s) and prior to payment
         of the full applicable Redemption Consideration or Optional Redemption
         Price to each holder, (i) the Notice(s) of Redemption at Option of
         Buyer Upon Triggering Event or the Notice(s) of Redemption at Option of
         Buyer Upon Major Transaction, as the case may be, shall be null and
         void with respect to those Series C Preferred Shares submitted for
         redemption and for which the applicable Redemption Consideration or
         Optional Redemption Price has not been paid, (ii) the Company shall
         immediately return any Series C Preferred Shares submitted to the
         Company by each holder for redemption under this Section 3(i) and for
         which the applicable Redemption Consideration or Optional Redemption
         Price has not been paid, (iii) the Fixed Conversion Price of such
         returned Series C Preferred Shares shall be adjusted to the lesser of
         (A) the Fixed Conversion Price as in effect on the date on which the
         Void Optional Redemption Notice(s) is delivered to the Company and (B)
         the lowest Closing Price during the period beginning on the date on
         which the Notice(s) of Redemption of Option of Buyer Upon Major
         Transaction or the Notice(s) of Redemption at Option of Buyer Upon
         Triggering event, as the case may be, is delivered to the Company and
         ending on the date on which the Void Optional Redemption Notice(s) is
         delivered to the Company; provided that no adjustment shall be made if
         such adjustment would result in an increase of the Fixed Conversion
         Price then in effect, and (iv) the Conversion Percentage in effect at
         such time shall be reduced by a number of percentage points equal to
         the product of (A) two and one-half (2.5) and (B) the number of months
         (prorated for partial months) in the period beginning on the date on
         which the Notice(s) of Redemption at Option of Buyer Upon Major
         Transaction or the Notice(s) of Redemption at Option of Buyer Upon
         Triggering Event, as the case may be, is delivered to the Company and
         ending on the date on which the Void Optional Redemption Notice(s) is
         delivered to the Company. In addition, if a redemption voided pursuant
         to this Section 3(i) was caused by a Triggering Event involving the
         Company's inability to issue Conversion Shares because of the Amex Cap,
         and if so directed by the holders of at least two-thirds (2/3) of the
         Series C Preferred Shares then outstanding, including shares of Series
         C Preferred Shares submitted for redemption pursuant to this Section 3
         with respect to which the applicable Optional Redemption Price has not
         been paid, in a Void Mandatory Redemption Notice, the Company shall
         immediately delist the Common Stock from AMEX and have the Common
         Stock, at such holders' option, listed on The Nasdaq SmallCap Market or
         traded on the electronic bulletin board or the "pink sheets".
         Notwithstanding the foregoing, in the event of a dispute as to the
         determination of the Closing Price or Major Transaction Consideration
         or the arithmetic calculation of the Redemption Rate, such dispute
         shall be resolved pursuant to Section 2(f)(iii) above with the term
         "Closing Price" or "Major Transaction Consideration" being substituted
         for the term "Lowest Sale Price"


                                      -12-

   13
         and the term "Redemption Rate" being substituted for the term
         "Conversion Rate". Payments provided for in this Section 3 shall have
         priority to payments to other stockholders in connection with a Major
         Transaction.

                  (4) Company's Right to Redeem at Its Election. Subject to
         Section 4(d) below, at any time, the Company shall have the right, at
         its option, to redeem ("REDEMPTION AT THE COMPANY'S ELECTION"), from
         time to time, any or all of the Series C Preferred Shares; provided
         that (i) the Notice of Redemption at the Company's Election (as defined
         below) is delivered on a date on which the Closing Price of the Common
         Stock is greater than $7.23 and (ii) the Company shall be entitled to
         redeem under this Section 4, if and only if, it redeems Series C
         Preferred Shares having an aggregate Liquidation Value of at least Five
         Million Dollars ($5,000,000). If the Company elects to redeem some, but
         not all, of the Series C Preferred Shares, the Company shall redeem an
         amount from each holder of Series C Preferred Shares equal to such
         holder's pro-rata amount (based on the number of Series C Preferred
         Shares held by such holder relative to the number of Series C Preferred
         Shares outstanding) of all Series C Preferred Shares being redeemed.

                      (a) Redemption Price at the Company's Election. The
         "REDEMPTION PRICE AT THE COMPANY'S ELECTION" shall be an amount per
         Series C Preferred Share equal to the greater of (i) the price
         calculated in accordance with the Redemption Rate as of the date of the
         Notice of Redemption at the Company's Election and (ii) 117.65% of the
         Liquidation Value of such Series C Preferred Share.

                      (b) Mechanics of Redemption at the Company's  Election. 
         The Company shall effect each such redemption no sooner than (30) days
         after delivering written notice thereof via facsimile and overnight
         courier ("NOTICE OF REDEMPTION AT THE COMPANY'S ELECTION") to each (i)
         holder of the Series C Preferred Shares and (ii) the Transfer Agent.
         Such Notice of Redemption at the Company's Election shall indicate (A)
         the number of shares of Series C Preferred Shares that have been
         selected for redemption, (B) the date that such redemption is to become
         effective (the "DATE OF REDEMPTION AT THE COMPANY'S ELECTION") and (C)
         the applicable Redemption Price at the Company's Election.
         Notwithstanding the above, any holder may convert into Common Stock
         pursuant to Section (2)(a) above, prior to the close of business on the
         day prior to the Date of Redemption at the Company's Election, any
         Series C Preferred Shares that such holder is otherwise entitled to
         convert, including Series C Preferred Shares that have been selected
         for redemption at the Company's election pursuant to this Section 4.

                      (c) Payment of Redemption Price. Each holder submitting 
         Series C Preferred Shares being redeemed under this Section 4 shall
         send such holder's Preferred Stock Certificates so redeemed to the
         Company or its Transfer Agent within five (5) business days after the
         Date of Redemption at the Company's Election, and the Company shall pay
         the applicable Redemption Price at the Company's Election to that
         holder in cash within five (5) business days after such holder's
         Preferred Stock Certificates are delivered to the Company or its
         Transfer Agent. If the Company shall fail to pay the


                                      -13-

   14
         applicable Redemption Price at the Company's Election to such holder on
         a timely basis as described in this Section 4(c), such unpaid amount
         shall bear interest at the rate of 2.5% per month until paid in full.
         Notwithstanding the foregoing, if the Company fails to pay the
         applicable Redemption Price at the Company's Election to a holder
         within the time period described in this Section 4 due to a dispute as
         to the determination of the Closing Price or the arithmetic calculation
         of the Redemption Rate, such dispute shall be resolved pursuant to
         Section 2(f)(iii) above with the term "Closing Price" being substituted
         for the term "Lowest Sale Price" and the term "Redemption Rate" being
         substituted for the term "Conversion Rate."

                      (d) Company Must Have Immediately Available Funds or
         Credit Facilities. The Company shall not be entitled to send any Notice
         of Redemption at the Company's Election pursuant to Section 4(b) above
         and begin the redemption procedure under this Section 4, unless it has:

                          (i)   the full amount of the Redemption Price at the 
         Company's Election in cash, available in a demand or other immediately
         available account in a bank or similar financial institution;

                          (ii)  credit facilities, with a bank or similar 
         financial institutions that are immediately available and unrestricted
         for use in redeeming the Series C Preferred Shares, in the full amount
         of the Redemption Price at the Company's Election;

                          (iii) a written agreement with a standby underwriter 
         or qualified buyer ready, willing and able to purchase from the Company
         a sufficient number of shares of stock to provide proceeds necessary to
         redeem any stock that is not converted prior to a Redemption at the
         Company's Election; or

                          (iv)  a combination of the items set forth in the 
         preceding clauses (i), (ii) and (iii), aggregating the full amount of
         the Redemption Price at the Company's Election.

                  (5) Inability to Fully Convert.

                      (a) Holder's Option if Company Cannot Fully Convert. If, 
         upon the Company's receipt of a Conversion Notice, the Company can not
         issue shares of Common Stock registered for resale under the
         Registration Statement for any reason, including, without limitation,
         because the Company (x) does not have a sufficient number of shares of
         Common Stock authorized and available, (y) is otherwise prohibited by
         applicable law or by the rules or regulations of any stock exchange,
         interdealer quotation system or other self-regulatory organization with
         jurisdiction over the Company or its Securities, including without
         limitation the AMEX Cap (as defined below), from issuing all of the
         Common Stock which is to be issued to a holder of Series C Preferred
         Shares pursuant to a Conversion Notice or (z) fails to have a
         sufficient number of shares of Common Stock registered for resale under
         the Registration Statement, then the Company shall issue as many shares
         of Common Stock as it is able to issue in accordance with


                                      -14-

   15
         such holder's Conversion Notice and pursuant to Section 2(f) above and,
         with respect to the unconverted Series C Preferred Shares, the holder,
         solely at such holder's option, can elect to:

                          (i)   require the Company to redeem from such holder 
         those Series C Preferred Shares for which the Company is unable to
         issue Common Stock in accordance with such holder's Conversion Notice
         ("MANDATORY REDEMPTION") at a price per Series C Preferred Share (the
         "MANDATORY REDEMPTION PRICE") equal to the greater of (x) 117.65% of
         the Liquidation Value of such share and (y) the Redemption Rate as of
         such Conversion Date;

                          (ii)  if the Company's inability to fully convert 
         Series C Preferred Shares is pursuant to Section 5(a)(z) above, require
         the Company to issue restricted shares of Common Stock in accordance
         with such holder's Conversion Notice and pursuant to Section 2(f)
         above;

                          (iii) void its Conversion Notice and retain or have 
         returned, as the case may be, the nonconverted Series C Preferred
         Shares that were to be converted pursuant to such holder's Conversion
         Notice; or

                          (iv)  if the Company's inability to fully convert 
         Series C Preferred Shares is pursuant to the Amex Cap described in
         Section 5(a)(y) above, require the Company to issue shares of Common
         Stock in accordance with such holder's Conversion Notice and pursuant
         to Section 2(f) above at a Conversion Price equal to the Average Market
         Price of the Common Stock for the five (5) consecutive trading days
         preceding such holder's Notice in Response to Inability to Convert (as
         defined below).

                      (b) Mechanics of Fulfilling Holder's Election. The
         Company shall immediately send via facsimile to a holder of Series C
         Preferred Shares, upon receipt of a facsimile copy of a Conversion
         Notice from such holder which cannot be fully satisfied as described in
         Section 5(a) above, a notice of the Company's inability to fully
         satisfy such holder's Conversion Notice (the "INABILITY TO FULLY
         CONVERT NOTICE"). Such Inability to Fully Convert Notice shall indicate
         (i) the reason why the Company is unable to fully satisfy such holder's
         Conversion Notice, (ii) the number of Series C Preferred Shares which
         cannot be converted and (iii) the applicable Mandatory Redemption
         Price. Such holder must within two (2) days of receipt of such
         Inability to Fully Convert Notice deliver written notice via facsimile
         to the Company ("NOTICE IN RESPONSE TO INABILITY TO CONVERT") of its
         election pursuant to Section 5(a) above.

                      (c) Payment of Redemption Price. If such holder shall
         elect to have its shares redeemed pursuant to Section 5(a)(i) above,
         the Company shall pay the Mandatory Redemption Price in cash to such
         holder within thirty (30) days of the Company's receipt of the holder's
         Notice in Response to Inability to Convert. If the Company shall fail
         to pay the applicable Mandatory Redemption Price to such holder on a
         timely basis as described in this Section 5(c) (other than pursuant to
         a dispute as to the determination of the Closing Price or the
         arithmetic calculation of the Redemption Rate),


                                      -15-

   16
         such unpaid amount shall bear interest at the rate of 2.5% per month
         (prorated for partial months) until paid in full. Until the full
         Mandatory Redemption Price is paid in full to such holder, such holder
         may void the Mandatory Redemption with respect to those Series C
         Preferred Shares for which the full Mandatory Redemption Price has not
         been paid and receive back such Series C Preferred Shares.
         Notwithstanding the foregoing, if the Company fails to pay the
         applicable Mandatory Redemption Price within such thirty (30) days time
         period due to a dispute as to the determination of the Closing Price or
         the arithmetic calculation of the Redemption Rate, such dispute shall
         be resolved pursuant to Section 2(f)(iii) above with the term "Closing
         Price" being substituted for the term "Lowest Sale Price" and the term
         "Redemption Rate" being substituted for the term "Conversion Rate".

                      (d) Pro-rata Conversion and Redemption. In the event
         the Company receives a Conversion Notice from more than one holder of
         Series C Preferred Shares on the same day and the Company can convert
         and redeem some, but not all, of the Series C Preferred Shares pursuant
         to this Section 5, the Company shall convert and redeem from each
         holder of Series C Preferred Shares electing to have Series C Preferred
         Shares converted and redeemed at such time an amount equal to such
         holder's pro-rata amount (based on the number of Series C Preferred
         Shares held by such holder relative to the number of Series C Preferred
         Shares outstanding) of all Series C Preferred Shares being converted
         and redeemed at such time.

                  (6) Reissuance of Certificates. In the event of a conversion
         or redemption pursuant to this Certificate of Designations of less than
         all of the Series C Preferred Shares represented by a particular
         Preferred Stock Certificate, the Company shall promptly cause to be
         issued and delivered to the holder of such Series C Preferred Shares a
         preferred stock certificate representing the remaining Series C
         Preferred Shares which have not been so converted or redeemed.

                  (7) Reservation of Shares. The Company shall, so long as any
         of the Series C Preferred Shares are outstanding, reserve and keep
         available out of its authorized and unissued Common Stock, solely for
         the purpose of effecting the conversion of the Series C Preferred
         Shares, such number of shares of Common Stock as shall from time to
         time be sufficient to effect the conversion of all of the Series C
         Preferred Shares then outstanding; provided that the number of shares
         of Common Stock so reserved shall at no time be less than 200% of the
         number of shares of Common Stock for which the Series C Preferred
         Shares are at any time convertible; provided further that such shares
         of Common Stock so reserved shall be allocated for issuance upon
         conversion of Series C Preferred Shares pro rata among the holders of
         Series C Preferred Shares based on the number of Series C Preferred
         Shares held by such holder relative to the total number of authorized
         Series C Preferred Shares.

                  (8) Voting Rights. Holders of Series C Preferred Shares shall
         have no voting rights, except as required by law, including but not
         limited to the General Corporation Law of the State of Delaware, and as
         expressly provided in this Certificate of Designations.


                                      -16-

   17
                  (9) Liquidation, Dissolution, Winding-Up. In the event of any
         voluntary or involuntary liquidation, dissolution or winding up of the
         Company, the holders of the Series C Preferred Shares shall be entitled
         to receive in cash out of the assets of the Company, whether from
         capital or from earnings available for distribution to its stockholders
         (the "PREFERRED FUNDS"), before any amount shall be paid to the holders
         of any of the capital stock of the Company of any class junior in rank
         to the Series C Preferred Shares in respect of the preferences as to
         the distributions and payments on the liquidation, dissolution and
         winding up of the Company, an amount per Series C Preferred Share equal
         to the sum of (i) $1,000 and (ii) an amount equal to the product of
         (.05) (N/365) ($1,000) (such sum being referred to as the "LIQUIDATION
         VALUE"); provided that, if the Preferred Funds are insufficient to pay
         the full amount due to the holders of Series C Preferred Shares and
         holders of shares of other classes or series of preferred stock of the
         Company that are of equal rank with the Series C Preferred Shares as to
         payments of Preferred Funds (the "PARI PASSU SHARES"), then each holder
         of Series C Preferred Shares and Pari Passu Shares shall receive a
         percentage of the Preferred Funds equal to the full amount of Preferred
         Funds payable to such holder as a percentage of the full amount of
         Preferred Funds payable to all holders of Series C Preferred Shares and
         Pari Passu Shares. The purchase or redemption by the Company of stock
         of any class, in any manner permitted by law, shall not, for the
         purposes hereof, be regarded as a liquidation, dissolution or winding
         up of the Company. Neither the consolidation or merger of the Company
         with or into any other Person, nor the sale or transfer by the Company
         of less than substantially all of its assets, shall, for the purposes
         hereof, be deemed to be a liquidation, dissolution or winding up of the
         Company. No holder of Series C Preferred Shares shall be entitled to
         receive any amounts with respect thereto upon any liquidation,
         dissolution or winding up of the Company other than the amounts
         provided for herein.

                  (10) Preferred Rank. All shares of Common Stock shall be of
         junior rank to all Series C Preferred Shares in respect to the
         preferences as to distributions and payments upon the liquidation,
         dissolution and winding up of the Company. The rights of the shares of
         Common Stock shall be subject to the preferences and relative rights of
         the Series C Preferred Shares. The Series C Preferred Shares shall be
         of equal rank with shares of the Company's Series B Convertible
         Preferred Stock. Without the prior express written consent of the
         holders of not less than two-thirds (2/3) of the then outstanding
         Series C Preferred Shares, the Company may not hereafter authorize or
         issue additional or other capital stock that is of senior rank to the
         Series C Preferred Shares in respect of the preferences as to
         distributions and payments upon the liquidation, dissolution and
         winding up of the Company. In the event of the merger or consolidation
         of the Company with or into another corporation, the Series C Preferred
         Shares shall maintain their relative powers, designations and
         preferences provided for herein and no merger shall result inconsistent
         therewith.

                  (11) Restriction on Redemption and Cash Dividends with respect
         to Other Capital Stock. Until all of the Series C Preferred Shares have
         been converted or redeemed as provided herein, the Company shall not
         redeem, or declare or pay any cash dividend or distribution on, its
         Common Stock without the prior express written consent


                                      -17-

   18
         of the holders of not less than two-thirds (2/3) of the then
         outstanding Series C Preferred Shares.

                  (12) Limitation on Number of Conversion Shares. The Company
         shall not be obligated to issue, in the aggregate, more than 20,946,476
         shares of Common Stock (such amount to be proportionately and equitably
         adjusted from time to time in the event of stock splits, stock
         dividends, combinations, reverse stock splits, reclassification,
         capital reorganizations and similar events relating to the Common
         Stock) (the "AMEX CAP") upon conversion of the Series C Preferred
         Shares, if issuance of a larger number of shares of Common Stock would
         constitute a breach of the Company's obligations under the rules or
         regulations of AMEX or any other principal securities exchange or
         market upon which the Common Stock becomes traded. The Amex Cap shall
         be allocated among the Series C Preferred Shares pro rata based on the
         total number of authorized Series C Preferred Shares.

                  (13) Vote to Change the Terms of Series C Preferred Shares.
         The affirmative vote at a meeting duly called for such purpose or the
         written consent without a meeting, of the holders of not less than
         two-thirds (2/3) of the then outstanding Series C Preferred Shares,
         shall be required for any change to this Certificate of Designations or
         the Company's Certificate of Incorporation which would amend, alter,
         change or repeal any of the powers, designations, preferences and
         rights of the Series C Preferred Shares.

                  (14) Lost or Stolen Certificates. Upon receipt by the Company
         of evidence satisfactory to the Company of the loss, theft, destruction
         or mutilation of any Preferred Stock Certificates representing the
         Series C Preferred Shares, and, in the case of loss, theft or
         destruction, of any indemnification undertaking by the holder to the
         Company and, in the case of mutilation, upon surrender and cancellation
         of the Preferred Stock Certificate(s), the Company shall execute and
         deliver new preferred stock certificate(s) of like tenor and date;
         provided, however, the Company shall not be obligated to re-issue
         preferred stock certificates if the holder contemporaneously requests
         the Company to convert such Series C Preferred Shares into Common
         Stock.




                                      -18-

   19
         IN WITNESS WHEREOF, the Company has caused this Certificate of
Designations to be signed by Virginia Walker, its Executive Vice President,
Finance and Administration, Chief Financial Officer and Secretary, as of the
17th day of January 1997.
