the number of shares of Common Stock into which such shares of Series B
Convertible Preferred Stock could be converted pursuant to the provisions of
Section 5 hereof at the record date for the determination of the shareholders
entitled to vote on such matters, or if no such record date is established, at
the date such vote is taken.

          b.  Common Stock.  Each holder of shares of Common Stock shall be
              ------------                                                 
entitled to one vote for each share thereof held.  Except as otherwise expressly
provided herein or as required by law, the holders of Series B Convertible
Preferred Stock and the holders of Common Stock shall vote together and not as
separate classes.

          Section 5.  Conversion.
                      ---------- 

          a.  Right to Convert.  Each share of Series B Convertible Preferred
              ----------------                                               
Stock shall be convertible, at any time or from time to time at the option of
the holder thereof, into fully

                                       3

 
paid and nonassessable shares of Common Stock without payment of any additional
consideration.

          b.  Conversion Price.  Each share of Series B Convertible Preferred
              ----------------                                               
Stock shall be convertible into the number of shares of Common Stock which
results from dividing the conversion price of the Series B Convertible Preferred
Stock that is in effect at the time of conversion (the "Conversion Price") into
the Original Issue Price for such Series B Convertible Preferred Stock.  As of
the filing of this Certificate of Determination, the initial Conversion Price
for the Series B Convertible Preferred Stock shall be equal to one-tenth
(1/10th) of the Original Issue Price.  The Conversion Price shall be subject to
adjustment from time to time as provided below.

          c.  Mechanics of Conversion.  Each holder of Series B Convertible
              -----------------------                                      
Preferred Stock who desires to convert the same into shares of Common Stock
shall surrender the certificate or certificates therefor, duly endorsed, at the
office of the Company or any transfer agent for the Series B Convertible
Preferred Stock or Common Stock, and shall give written notice to the Company at
such office that such holder elects to convert the same and shall state therein
the number of shares of Series B Convertible Preferred Stock being converted.
Thereupon the Company shall promptly, but in no event more than two (2) days
after receipt of such notice, issue and deliver at such office to such holder a
certificate or certificates for the number of shares of Common Stock to which
such holder is entitled and shall promptly pay in cash any declared and unpaid
dividends on the shares of Series B Convertible Preferred Stock being converted.
Such conversion shall be deemed to have been made immediately prior to the close
of business on the date of such surrender of the certificate representing the
shares of Series B Convertible Preferred Stock to be converted, and the person
entitled to receive the shares of Common Stock issuable upon such conversion
shall be treated for all purposes as the record holder of such shares of Common
Stock on such date.  If a surrender for conversion occurs after the record date
fixed by the Company for the determination of holders of Common Stock entitled
to receive a dividend or other distribution payable in additional shares of
Common Stock, but prior to the issuance of such additional shares, the
Conversion Price shall, subject to such issue, be recomputed in accordance with
subsection (e) of this Section 5.

          d.  Adjustment for Stock Splits and Combinations.  If the Company at
              --------------------------------------------                    
any time or from time to time after the filing of this Certificate of
Determination effects a subdivision of the outstanding Common Stock, the
Conversion Price for the Series B Convertible Preferred Stock in effect
immediately before that subdivision shall be proportionately decreased, and
conversely, if the Company at any time or from time to time after the filing of
this Certificate of Determination combines the outstanding shares of Common
Stock into a smaller number of shares, the Conversion Price for the Series B
Convertible Preferred Stock in effect immediately before the combination shall
be proportionately increased.  Any adjustment under this subsection (d) shall
become effective at the close of business on the date the subdivision or
combination becomes effective.

          e.  Adjustment for Common Stock Dividends.  If the Company at any time
              -------------------------------------                             
or from time to time after the filing of this Certificate of Determination
makes, or fixes a record 

                                       4

 
date for the determination of holders of Common Stock entitled to receive, a
dividend or other distribution payable in additional shares of Common Stock, in
each such event the applicable Conversion Price for the Series B Convertible
Preferred Stock that is then in effect shall be decreased as of the time of such
issuance or, in the event such record date is fixed, as of the close of business
on such record date, by multiplying the applicable Conversion Price then in
effect for the Series B Convertible Preferred Stock by a fraction (1) the
numerator of which is the total number of shares of Common Stock issued and
outstanding immediately prior to the time of such issuance or the close of
business on such record date, and (2) the denominator of which is the total
number of shares of Common Stock issued and outstanding immediately prior to the
time of such issuance or the close of business on such record date plus the
number of shares of Common Stock issuable in payment of such dividend or
distribution; provided, however, that if such record date is fixed and such
dividend is not fully paid or if such distribution is not fully made on the date
fixed therefor, the applicable Conversion Price for the Series B Convertible
Preferred Stock shall be recomputed accordingly as of the close of business on
such record date and thereafter the applicable Conversion Price for the Series B
Convertible Preferred Stock shall be adjusted pursuant to this subsection (e) to
reflect the actual payment of such dividend or distribution.

          f.  Adjustment for Other Dividends and Distributions.  If the Company
              ------------------------------------------------                 
at any time or from time to time after the filing of this Certificate of
Determination makes, or fixes a record date for the determination of holders of
Common Stock entitled to receive, a dividend or other distribution payable in
securities of the Company other than shares of Common Stock, in each such event
provision shall be made so that the holders of the Series B Convertible
Preferred Stock shall receive upon conversion thereof, in addition to the number
of shares of Common Stock receivable thereupon, the amount of securities of the
Company which they would have received had their Series B Convertible Preferred
Stock been converted into Common Stock on the date of such event and had they
thereafter, during the period from the date of such event to and including the
conversion date, retained such securities receivable by them as aforesaid during
such period, subject to all other adjustments called for during such period
under this Section 5 with respect to the rights of the holders of the Series B
Convertible Preferred Stock or with respect to such other securities by their
terms.

          g.  Adjustment for Reclassification, Exchange and Substitution.  If at
              ----------------------------------------------------------        
any time or from time to time after the filing of this Certificate of
Determination the Common Stock issuable upon the conversion of the Series B
Convertible Preferred Stock is changed into the same or a different number of
shares of any class or classes of stock, whether by recapitalization,
reclassification or otherwise (other than a subdivision or combination of shares
or stock dividend or a reorganization, merger, consolidation or sale of assets,
provided for elsewhere in this Section 5) in any such event each holder of the
Series B Convertible Preferred Stock shall have the right thereafter to convert
such stock into the kind and amount of stock and other securities and property
receivable upon such recapitalization, reclassification or other change by
holders of the number of shares of Common Stock into which such shares of the
Series B Convertible Preferred Stock could have been converted immediately prior
to such recapitalization, reclassification or change, all subject to further
adjustment as provided herein or with respect to such other securities or
property by the terms thereof.

          h.  Conversion Price Adjustments of Series B Convertible Preferred
              --------------------------------------------------------------
Stock.  The Conversion Price of the Series B Convertible Preferred Stock shall
- -----                                                                         
be subject to adjustment from time to time as follows:

          (i)   If the Company at any time or from time to time after the filing
of this Certificate of Determination issues or sells, or is deemed by the
express provisions of this subsection (h) to have issued or sold, any Additional
Stock for consideration per share which is less than the Conversion Price for
the Series B Convertible Preferred Stock in effect immediately prior to such
issuance, the then existing Conversion Price for the Series B Convertible
Preferred Stock shall be forthwith reduced to the per share price received or
deemed received by the Company upon such issuance or sale, or deemed issuance or
sale, of such Additional Stock; provided, however, that no adjustment shall be
made pursuant to this subsection (h) and this subsection (h) shall not apply, if
an adjustment would otherwise be called for pursuant to any of subsections (d),
(e), (f), (g) or (i).  Any adjustment to the Conversion Price for the Series B
Convertible Preferred Stock pursuant to the preceding sentence shall be
effective as of the opening of business on the date of the issuance or sale, or
deemed issuance or sale, of such Additional Stock by the Company.  Whenever the
Company issues or sells, or is deemed to issue or sell, any Additional Stock,
the per share fair market value of the Additional Stock as of the date of such
issuance or sale, or deemed issuance or sale, shall be determined in good faith
by the Company's Board.

          (ii)  No adjustment of the Conversion Price for the Series B
Convertible Preferred Stock pursuant to this subsection (h) shall be made in an
amount less than one cent per share, provided that any adjustments which are not
required to be made by reason of this sentence shall be carried forward and
shall be taken into account in any subsequent adjustment.  Except to the limited
extent provided for in subsections (h)(v)(C) and (D), no adjustment of such
Conversion Price pursuant to this subsection (h) shall have the effect of
increasing the Conversion Price above the Conversion Price in effect immediately
prior to such adjustment.

          (iii) In the case of the issuance of Common Stock for cash, the
consideration shall be deemed to be the amount of cash paid therefor before
deducting any underwriters' or brokers' discounts, or commissions allowed, paid
or incurred by this corporation for any underwriting or otherwise in connection
with the issuance and sale thereof.

          (iv)  In the case of the issuance of Common Stock for a consideration
in whole or in part other than cash, the consideration other than cash shall be
deemed to be the fair value thereof as reasonably determined in good faith by
the Board.

          (v)   Solely for the purpose of calculating the amount of any
adjustment which is required, in the case of the issuance of options to purchase
or rights to subscribe for Common Stock, securities by their terms convertible
into or exchangeable for Common Stock or options to purchase or rights to
subscribe for such convertible or exchangeable securities (which are not
excluded from the definition of Additional Stock), the following provisions
shall apply for all purposes of this subsection (h):

                                       6

 
                    A.  The aggregate maximum number of shares of Common Stock
          deliverable upon exercise of such options to purchase or rights to
          subscribe for Common Stock shall be deemed to have been issued at the
          time such options or rights were issued and for a consideration equal
          to the consideration (determined in the manner provided in subsections
          (h)(iii) and (iv)), if any, received by the Company upon the issuance
          of such options or rights plus the minimum exercise price provided in
          such options or rights for the Common Stock covered thereby.

                    B.  The aggregate maximum number of shares of Common Stock
          deliverable upon conversion of or in exchange for any such convertible
          or exchangeable securities or upon the exercise of options to purchase
          or rights to subscribe for such convertible or exchangeable securities
          and subsequent conversion or exchange thereof shall be deemed to have
          been issued at the time such securities were issued or such options or
          rights were issued and for a consideration equal to the consideration,
          if any, received by the Company for any such securities and related
          options or rights (excluding any cash received on account of accrued
          interest or accrued dividends), plus the minimum additional
          consideration, if any, to be received by the Company upon the
          conversion or exchange of such securities or the exercise of any
          related options or rights (the consideration in each case to be
          determined in the manner provided in subsections (h)(iii) and (iv)).

                    C.  In the event of any change in the number of shares of
          Common Stock deliverable or in the consideration payable to the
          Company upon exercise of such options or rights or upon conversion or
          in exchange for such convertible or exchangeable securities,
          including, but not limited to, a change resulting from the
          antidilution provisions thereof, the applicable Conversion Price of
          the Series B Convertible Preferred Stock to the extent in any way
          affected by or computed using such options, rights or securities,
          shall be recomputed to reflect such change, but no further adjustment
          shall be made for the actual issuance of Common Stock or any payment
          of such consideration upon the exercise of any such options or rights
          or the conversion or exchange of such securities.

                    D.  Upon the expiration of any such options or rights, the
          termination of any such rights to convert or exchange or the
          expiration of any options or rights related to such convertible or
          exchangeable securities, the applicable Conversion Price of the Series
          B Convertible Preferred Stock to the extent in any way affected by or
          computed using such options, rights or securities or options or rights
          related to such securities, shall be recomputed to reflect the
          issuance of only the number of shares of Common Stock (and convertible
          or exchangeable securities which remain in effect) actually issued
          upon the exercise of such options or rights, upon the conversion or
          exchange of such securities or upon the exercise of the options or
          rights related to such securities.

                    E.  The number of shares of Common Stock deemed issued and
          the consideration deemed paid therefor pursuant to subsections
          (h)(v)(A) and (B) shall be appropriately adjusted to reflect any
          change, termination or expiration of the type described in either
          subsections (h)(v)(C) or (D).


          i.  Reorganizations, Mergers, Consolidations or Sales of Assets.  If
              -----------------------------------------------------------     
at any time or from time to time after the filing of this Certificate of
Determination there is a capital reorganization of the Common Stock (other than
a recapitalization, subdivision, combination, reclassification or exchange of
shares provided for elsewhere in this Section 5) or a merger or consolidation of
the Company into or with another corporation, or the sale of all or
substantially all the Company's properties and assets to any other person, as a
part of such reorganization, merger, consolidation or sale, provision shall be
made so that the holders of the Series B Convertible Preferred Stock shall
thereafter be entitled to receive upon conversion of the Series B Convertible
Preferred Stock the number of shares of stock or other securities or property of
the Company, or of the successor corporation resulting from such merger or
consolidation or sale, to which a holder of the number of shares of Common Stock
deliverable upon conversion would have been entitled on such capital
reorganization, merger, consolidation or sale, subject to adjustment in respect
of such stock or securities by the terms thereof.  In any such case, appropriate
adjustment shall be made in the application of the provisions of this Section 5
with respect to the rights of the holders of Series B Convertible Preferred
Stock after the reorganization, merger, consolidation or sale to the end that
the provisions of this Section 5 (including adjustment of the Conversion Price
then in effect for the Series B Convertible Preferred Stock and the number of
shares purchasable upon conversion of the Series B Convertible Preferred Stock)
shall be applicable after that event and be as nearly equivalent as practicable.

          j.  Accountants' Certificate of Adjustment.  In each case of an
              --------------------------------------                     
adjustment or readjustment of the Conversion Price and the number of shares of
Common Stock or other securities issuable upon conversion of the Series B
Convertible Preferred Stock, the Company, at its expense, shall cause
independent public accountants of recognized standing selected by the Company
(who may be the independent public accountants then auditing the books of the
Company) to compute such adjustment or readjustment in accordance with the
provisions hereof and prepare a certificate showing such adjustment or
readjustment, and shall mail such certificate, by first class mail, postage
prepaid, to each registered holder of the Series B Convertible Preferred Stock
at the holder's address as shown in the Company's books.  The certificate shall
set forth such adjustment or readjustment, showing in detail the facts upon
which such adjustment or readjustment is based, including a statement of (1) the
Conversion Price at the time in effect, (2) the number of additional shares of
Common Stock and (3) the type and amount, if any, of other property which at the
time would be received upon conversion of the Series B Convertible Preferred
Stock.

          k.  Notices of Record Date.  Upon (i) any taking by the Company of a
              ----------------------                                          
record of the holders of any class of securities for the purpose of determining
the holders thereof who are entitled to receive any dividend or other
distribution, or (ii) any capital reorganization of the Company, any

                                       8

 
reclassification or recapitalization of the capital stock of the Company, any
merger or consolidation of the Company with or into any other corporation, or
any transfer of all or substantially all the assets of the Company to any other
person or any voluntary or involuntary dissolution, liquidation or winding up of
the Company, the Company shall mail to each holder of Series B Convertible
Preferred Stock at least twenty (20) days prior to the record date specified
therein a notice specifying (1) the date on which any such record is to be taken
for the purpose of such dividend or distribution and a description of such
dividend or distribution, (2) the date on which any such reorganization,
reclassification, transfer, consolidation, merger, dissolution, liquidation or
winding up is expected to become effective, and (3) the date, if any, that is to
be fixed as to when the holders of record of Common Stock or Series B
Convertible Preferred Stock (or other securities) shall be entitled to exchange
their shares of Common Stock or Series B Convertible Preferred Stock (or other
securities) for securities or other property deliverable upon such
reorganization, reclassification, transfer, consolidation, merger, dissolution,
liquidation or winding up.

          l.  Automatic Conversion.
              -------------------- 

          (1) Each share of Series B Convertible Preferred Stock shall
automatically be converted into shares of Common Stock based on the then-
effective Conversion Price for such share of Series B Convertible Preferred
Stock immediately upon any event that would cause the Series B Convertible
Preferred Stock to be required to be registered pursuant to Section 12(g) of the
Securities Exchange Act of 1934, as amended, or any successor provision thereto.

          (2) Each share of the Series B Convertible Preferred Stock shall
automatically be converted into shares of Common Stock based on the then-
effective Conversion Price upon the filing with the Secretary of the Company of
the written approval of the holders of more than fifty percent of the
outstanding shares of the Series B Convertible Preferred Stock.

          (3) Upon the occurrence of the events specified in paragraphs (1) or
(2) above, the outstanding shares of Series B Convertible Preferred Stock shall
be converted automatically without any further action by the holders of such
shares and whether or not the certificates representing such shares are
surrendered to the Company or its transfer agent; provided, however, that the
Company shall not be obligated to issue certificates evidencing the shares of
Common Stock issuable upon such conversion unless the certificates evidencing
such shares of Series B Convertible Preferred Stock are either delivered to the
Company or its transfer agent as provided below, or the holder notifies the
Company or its transfer agent that such certificates have been lost, stolen or
destroyed and executes an agreement reasonably satisfactory to the Company to
indemnify the Company from any loss incurred by it in connection with such
certificates.  Upon the occurrence of such automatic conversion of the Series B
Convertible Preferred Stock, the holders of Series B Convertible Preferred Stock
shall surrender the certificates representing such shares at the office of the
Company or any transfer agent for the Series B Convertible Preferred Stock or
Common Stock.  Thereupon, there shall be issued and delivered to such holder
promptly at such office and in its name as shown on such surrendered certificate
or certificates, a certificate or certificates for the number of shares of
Common Stock into which the shares of Series B Convertible Preferred Stock
surrendered were convertible on 

                                       9

 
the date on which such automatic conversion occurred, and the Company shall
promptly pay in cash or, at the option of the Company, Common Stock (taken at
the Common Stock's Fair Market Value as of the date of such conversion), or, at
the option of the Company, a combination, all declared and unpaid dividends on
the shares of Series B Convertible Preferred Stock being converted to and
including the date of such conversion.

          m.  Fractional Shares.  No fractional shares of Common Stock shall be
              -----------------                                                
issued upon conversion of Series B Convertible Preferred Stock.  In lieu of any
fractional share to which the holder would otherwise be entitled, the Company
shall pay cash equal to the product of such fraction multiplied by the Common
Stock's Fair Market Value on the date of conversion.

          n.  Reservation of Stock Issuable Upon Conversion.  The Company shall
              ---------------------------------------------                    
at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series B Convertible Preferred Stock, such number of its
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all outstanding shares of the Series B Convertible Preferred
Stock; and if at any time the number of authorized but unissued shares of Common
Stock shall not be sufficient to effect the conversion of all then outstanding
shares of the Series B Convertible Preferred Stock, the Company will take such
corporate action as may, in the opinion of its counsel, be necessary to increase
its authorized but unissued shares of Common Stock to such number of shares as
shall be sufficient for such purposes.

          o.  Notices.  Any notice required by the provisions of this Section 5
              -------                                                          
to be given to holders of shares of the Series B Convertible Preferred Stock
shall be deemed given upon the earlier of actual receipt or seventy-two (72)
hours after the same has been deposited in the United States mail, by certified
or registered mail, return receipt requested, postage prepaid, and addressed to
each holder of record at the address of such holder appearing on the books of
the Company.

          p.  Payment of Taxes.  The Company will pay all taxes (other than
              ----------------                                             
taxes based upon income) and other governmental charges that may be imposed with
respect to the issue or delivery of shares of Common Stock upon conversion of
shares of Series B Convertible Preferred Stock, including without limitation any
tax or other charge imposed in connection with any transfer involved in the
issue and delivery of shares of Common Stock in a name other than that in which
the shares of Series B Convertible Preferred Stock so converted were registered.

          q.  No Dilution or Impairment.  The Company shall not amend its Ninth
              -------------------------                                        
Amended and Restated Articles of Incorporation or participate in any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, for the purpose of avoiding or
seeking to avoid the observance or performance of any of the terms to be
observed or performed hereunder by the Company, but shall at all times in good
faith assist in carrying out all such action as may be reasonably necessary or
appropriate in order to protect the conversion rights of the holders of the
Series B Convertible Preferred Stock against dilution or other impairment.

                                       10

 
          r.  Cancellation of Series B Convertible Preferred Stock on
              -------------------------------------------------------
Conversion.  All certificates of the Series B Convertible Preferred Stock
surrendered for conversion or otherwise retired shall be appropriately cancelled
on the books of the Company, and the shares so converted or otherwise retired
represented by such certificates shall not be reissuable as shares of the Series
B Convertible Preferred Stock so converted, but shall instead be restored to the
status of authorized but unissued Preferred Stock of the Company, undesignated
as to the series and subject to designation by the Board of Directors of the
Company pursuant to Article III, Section 2 of the Ninth Amended and Restated
Articles of Incorporation.
