                 (Street Address of corporation in Massachusetts)


do hereby certify that a meeting of the directors of the corporation held on 
November 9, 1998, the following vote establishing and designating a class or 
series of stock and determining the relative rights and preferences thereof was 
duly adopted:


                  See continuation Sheets 1-21
                  Attached Hereto


 
         1.   Number, Designation and Rank.
              ----------------------------

                  (a) This series shall consist of 500,000 preferred shares in
the Corporation and shall be designated the Series A Convertible Preferred Stock
("Series A Preferred Stock").
  ------------------------

                  (b) The Series A Preferred Stock shall, with respect to
dividend rights and rights on Liquidation rank prior to all classes or series of
equity securities of the Corporation, including the Common Stock.

         2.   Dividends.
              ---------

                  (a) The holders of Series A Preferred Stock shall be entitled
to receive, out of funds legally available for that purpose, with respect to
each share of Series A Preferred Stock, before any dividends or other
distributions shall be declared and paid or set aside for the Common Stock or
any other class or series of stock of the Corporation ranking on a parity with
or junior to the Series A Preferred Stock with respect to dividends, dividends
at the Applicable Dividend Rate on the sum of (x) the Original Cost of such
share of Series A Preferred Stock plus (y) all accumulated and unpaid dividends
thereon deferred in accordance with Section 2(c)). Subject to Section 2(c), such
dividends shall be paid in cash quarterly in arrears on each March 30, June 30,
September 30 and December 30 (unless such day is not a Business Day, in which
event on the next succeeding Business Day) (each a "Dividend Payment Date") and
                                                    ---------------------
shall be calculated on the basis of a year of 360 days comprised of twelve
30-day months. All cash payments of dividends with respect to the Series A
Preferred Stock shall be made in such coin or currency of the United States of
America as at the time of payment shall be legal tender therein for the payment
of public and private debts.

                  (b) Dividends shall accrue and compound on a quarterly basis
at the Applicable Dividend Rate regardless of whether the Board has declared a
dividend payment or whether there are any profits, surplus or other funds of the
Corporation legally available for dividends. Any dividend which accrues pursuant
to this Section 2 shall be classified as "accumulated dividends" and shall
remain "accumulated and unpaid dividends" until paid or otherwise canceled
pursuant to this Certificate of Vote of Directors Establishing a Class or Series
of Stock. Dividends on each share of Series A Preferred Stock shall accrue
pursuant to this Section 2 from and including the Original Issuance Date to and
including the date such share is redeemed in full or such share is fully
converted into Common Stock pursuant to Section 5 below. The dividends payable
with respect to the Series A Preferred Stock shall be paid to the holders of
shares of the Series A Preferred Stock as they appear on the stock records of
the Corporation on the applicable Dividend Payment Date.

                  (c) Unless the Requisite Series A Stockholders, at their
option and in their sole discretion, require the Corporation to make payment in
cash of such dividend payable on a Dividend Payment Date with respect to the
outstanding shares of Series A Preferred Stock, such dividends shall not be paid
in cash but shall continue to accrue in accordance with this Section 2 and shall
not otherwise be paid in cash as a dividend pursuant to Section 2(a) on a later
Dividend Payment Date without the prior written consent of the Requisite Series
A Stockholders. The Requisite Series A Stockholders shall give irrevocable
written notice to the Corporation of their 

 
election to defer such cash payment of dividends not less than 5 Business Days
nor more than 60 Business Days prior to the applicable Dividend Payment Date.

                  (d) Except as otherwise approved by the Requisite Series A
Stockholders, so long as any shares of the Series A Preferred Stock are
outstanding, the Corporation shall not pay or declare or set apart for payment
any dividend or make any other distribution or other payment on or with respect
to the Common Stock or any class or series of stock of the Corporation ranking
on a parity with or junior to the Series A Preferred Stock with respect to
dividends or redeem, repurchase or otherwise acquire any such stock unless the
Corporation has paid, or at the same time pays in cash, all accumulated and
unpaid dividends on the Series A Preferred Stock pursuant to this Section 2 that
have accrued through the date of such action.

                  (e) Except as otherwise provided herein, if at any time the
Corporation pays less than the total amount of accumulated and unpaid dividends
with respect to the Series A Preferred Stock, such payment shall be distributed
ratably among the holders of the Series A Preferred Stock based upon the number
of shares of the Series A Preferred Stock held by each such holder.

                  (f) After payment of all dividends owing to holders of Series
A Preferred Stock, such holders shall not participate in dividends thereafter
paid on the Common Stock.

         3.   Liquidation. Upon a Liquidation, after payment or provision for
              -----------
payment of the debts and other liabilities of the Corporation, the holders of
Series A Preferred Stock shall be entitled to receive, out of the remaining
assets of the Corporation available for distribution to its stockholders with
respect to each share of Series A Preferred Stock, an amount equal to the
Liquidation Amount of such share before any distribution shall be made to the
holders of the Common Stock or any other class of capital stock of the
Corporation ranking junior to the Series A Preferred Stock. If upon any
Liquidation the assets of the Corporation available for distribution to its
stockholders shall be insufficient to pay the holders of Series A Preferred
Stock the full Liquidation Amount to which they shall be entitled, the holders
of Series A Preferred Stock shall share in any distribution of assets in
accordance with such full Liquidation Amount (pro rata in accordance with the
total Liquidation Amount that each such holders would have received had there
been such sufficient assets). After the payment of the full Liquidation Amount
to the holders of Series A Preferred Stock, such holders shall have no claim to
any remaining assets of the Corporation, if any.

         4.   Mandatory and Optional Redemption.
              --------------------------------- 

                  (a) Any redemption effected in accordance with this Section 4
shall occur at the following redemption prices (expressed in percentages of the

the most recent Dividend Payment Date to the redemption date (assuming solely
for this purpose that dividends accrue on a daily basis at the Applicable
Dividend Rate), payable solely in cash to the holder of a share of Series A
Preferred Stock.

             Year                                                     Redemption
             ----                                                     Percentage
                                                                      ----------

  On or after November 12, 2001 and prior to November 12, 2002           102%

  On or after November 12, 2002 and prior to November 12, 2003           101%

  On or after November 12, 2003                                          100%

As used herein, "Redemption Amount" means, with respect to each share of Series
                 -----------------
A Preferred Stock, the sum of (x) the Original Cost of such share plus (y) all
accumulated and unpaid dividends with respect thereto to (and including) the
most recent Dividend Payment Date.

                  (b) In the event a Change of Control shall have occurred, the
Corporation shall be obligated to, at the option and sole discretion of each
holder of shares of Series A Preferred Stock, (x) redeem such shares of Series A
Preferred Stock as such holder elects immediately at the then applicable
Redemption Price, plus accumulated and unpaid dividends with respect thereto
from (but not including) the most recent Dividend Payment Date to the redemption
date (assuming solely for this purpose that dividends accrue on a daily basis at
the Applicable Dividend Rate), payable in cash, or (y) convert such shares of
Series A Preferred Stock as such holder elects immediately into shares of Common
Stock in accordance with Section 5 hereof.

                  (c) The shares of Series A Preferred Stock may be redeemed on
any Business Day after the Original Issuance Date at the option of the
Corporation at the then applicable Redemption Price, plus accumulated and unpaid
dividends with respect thereto from (but not including) the most recent Dividend
Payment Date to the redemption date (assuming solely for this purpose that
dividends accrue on a daily basis at the Applicable Dividend Rate), payable in
cash; provided that the Corporation shall not redeem less than 100,000 shares of
      --------
Series A Preferred Stock (or any multiple of 100,000 shares in excess thereof)
unless it is redeeming all shares of Series A Preferred Stock then outstanding.
Notwithstanding the immediately preceding sentence, the Corporation shall not
have the right to redeem any shares of Series A Preferred Stock unless the
Corporation also elects to redeem on the Redemption Date, as nearly as is
possible, the same proportionate amount of the aggregate number of shares of
Series A Preferred Stock held by each holder of shares of Series A Preferred
Stock. The date established for any redemption pursuant to this Section 4(c) is
referred to herein as the "Redemption Date".
                           ---------------

                  (d) At least 15 Business Days but not more than 30 Business
Days prior to a Redemption Date for any redemption made pursuant to Section
4(c), the Corporation shall provide written notice of such redemption (a
"Redemption Notice") to the holders of the shares of Series A Preferred Stock
 -----------------
indicating that the Corporation shall redeem the shares of Series A Preferred
Stock. Such notice shall call upon the holder to surrender to the Corporation on
the Redemption Date, at the place or places designated in such notice, the
certificate or certificates 


                                      -3-

 
representing shares of Series A Preferred Stock to be redeemed, held by such
holder, free and clear of any encumbrances. Such surrendered certificate or
certificates shall be canceled.

                  (e) The Redemption Notice shall also specify the number of
shares of Series A Preferred Stock to be redeemed, the Redemption Date, the
Redemption Price, the place or places of payment, that payment will be made upon
presentation and surrender of each shares of Series A Preferred Stock, that
dividends accumulated and unpaid from (but not including) the most recent
Dividend Payment Date to the Redemption Date (assuming solely for this purpose
that dividends accrue on a daily basis at the Applicable Dividend Rate) will be
paid as specified in said notice, that on and after said date dividends will
cease to accumulate. Such Redemption Notice shall also state the current
Conversion Price and the date on which the right to convert the shares of Series
A Preferred Stock or portions thereof into Common Stock will expire.

                  (f) If a Redemption Notice has been given as above provided,
the applicable Redemption Price specified in Section 4(a) hereof relating to
such redemption shall become due and payable on the on the date and at the place
stated in such notice, together dividends accumulated and unpaid from (but not
including) the most recent Dividend Payment Date to the Redemption Date
(assuming solely for this purpose that dividends accrue on a daily basis at the
Applicable Dividend Rate), and on and after said date (unless the Corporation
shall default in the payment of such shares of Series A Preferred Stock to be
redeemed at the applicable Redemption Price, together with such dividends
accumulated and unpaid to said date) dividends on the shares of Series A
Preferred Stock specified in the Redemption Notice shall cease to accumulate,
and the holders of such shares of Series A Preferred Stock shall have no right
in respect of such shares except the right to receive the Redemption Price and
the accumulated and unpaid dividends to Redemption Date. On presentation and
surrender of the certificate for shares of Series A Preferred Stock to be
redeemed at a place of payment specified in the Redemption Notice, such shares
shall be paid and redeemed by the Corporation at the Redemption Price, together
with any dividends accumulated and unpaid thereon from (but not including) the
most recent Dividend Payment Date to the Redemption Date (assuming solely for
this purpose that dividends accrue on a daily basis at the Applicable Dividend
Rate) and the Corporation shall issue to the holder a new certificate with
respect to any shares of Series A Preferred Stock represented by the surrendered
certificate to the extent such shares have not otherwise been redeemed. If any
shares of Series A Preferred Stock are called for redemption but shall not be so
paid upon surrender thereof for redemption, such shares shall, until paid or
duly provided for, accumulate dividends from the Redemption Date at the rate
provided for herein.

                  (g) Notwithstanding any other provisions contained in this
Certificate of Vote of Directors Establishing a Class or Series of Stock to the
contrary, if any redemption of shares of Series A Preferred Stock occurs on or
prior to December 30, 1998, then each reference in this Section 4 to "the most
recent Dividend Payment Date" shall be deemed instead to refer to "the Original
Issuance Date".

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

                                      -4-

 
                  (a) Generally. Subject to the provisions of this Section 5 and
Section 6, each holder of each share of Series A Preferred Stock shall have the
right, on any Business Day, at such holder's option, to convert such share into
the number of fully paid and non-assessable shares of Common Stock equal to the
quotient obtained by dividing (A) the sum of (x) the Original Cost of such share
plus (y) all accumulated and unpaid dividends with respect thereto to the date
of conversion by (B) the Conversion Price (as defined below), as last adjusted
and then in effect; provided that any such conversion occurring (I) on a date
                    --------
after receipt of a Redemption Notice and on or prior to the redemption which is
the subject of such notice or (II) upon a Change of Control or (III) following
the commencement of a Non-Consensual Tender Offer, shall be into that number of
shares of Common Stock equal to the quotient obtained by dividing (x) the
Redemption Price which would be applicable if such shares of Series A Preferred
Stock were redeemed, rather than converted, on the Conversion Date (plus any
dividends accumulated and unpaid with respect thereto from (but not including)
the most recent Dividend Payment Date (or the Original Issuance Date if no
Dividend Payment Date has occurred) to the Conversion Date (assuming solely for
this purpose that dividends accrue on a daily basis at the Applicable Dividend
Rate)) divided by (y) the product of (1) the applicable Redemption Conversion
Factor corresponding to the date upon which the Redemption Date (or the Change
of Control or a Consensual Tender Offer) occurs (as set forth below) and (2) the
lesser of the Conversion Price (as last adjusted an then in effect), the Market
Price (determined as of the Conversion Date) of the Common Stock and (if
applicable) the Non-Consensual Tender Offer Price.

                               Year                                  Redemption

The conversion price per share at which shares of Common Stock shall be issuable
upon conversion of each share of Series A Preferred Stock (the "Conversion
                                                                ----------
Price") shall initially be equal to $1.818. The Conversion Price shall be
- - -----
subject to adjustment from time to time pursuant to Section 6. Notwithstanding
any call for redemption pursuant to Section 4, the right to convert shares so
called for redemption shall terminate at the close of business on the Business
Day immediately preceding the Redemption Date unless the Corporation shall
default in making the exchange and payment of any amount payable upon such
exchange.

                  (b) Exercise Procedure.


                                      -5-

 
               (i)    In order to exercise the conversion privilege, a holder of
shares of the Series A Preferred Stock shall provide prior written notice of
such exercise at least 10 Business Days, but not more then 60 Business Days,
prior to such conversion; provided that only one Business Day's prior written
notice shall be required if the Corporation has delivered a Notice of Redemption
to the holders of shares of the Series A Preferred Stock or if a Non-Consensual
Tender Offer has commenced. The date established for any such conversion
pursuant to this Section 5 is referred to herein as the "Conversion Date." On or
                                                         ---------------
prior to the Conversion Date, the holder of shares of the Series A Preferred
Stock to be converted shall surrender the certificate or certificates
representing such shares of Series A Preferred Stock at the office of the
Corporation, duly endorsed or assigned in blank. Unless the shares issuable on
conversion are to be issued in the same name as the name in which shares of
Series A Preferred Stock are registered, each share surrendered for conversion
shall be accompanied by instruments of transfer, in form satisfactory to the
Corporation, duly executed by the holder of shares of the Series A Preferred
Stock to be converted or by such holder's duly authorized attorney and an amount
sufficient to pay any transfer or similar tax. Each conversion shall be deemed
to have been effected immediately prior to the close of business on the
Conversion Date.

               (ii)   On the Conversion Date, the Corporation shall issue and
shall deliver to such holder of shares of the Series A Preferred Stock being
converted, or on such holder's written order to such holder's transferee, a
certificate or certificates for the whole number of shares of Common Stock
issuable upon the conversion of such shares and the Corporation shall issue such
holder a new certificate with respect to the unconverted shares of Series A
Preferred Stock.

               (iii)  The person in whose name or names any certificate or
certificates for shares of Common Stock shall be issuable upon such conversion
shall be deemed to have become the holder of record of the shares of Common
Stock represented thereby at such time on such date.

               (iv)   All shares of Common Stock delivered upon conversion of
shares of Series A Preferred Stock will upon delivery be duly and validly issued
and fully paid and non-assessable, free of all liens and charges and not subject
to any preemptive rights. Upon the surrender of shares of Series A Preferred
Stock, the shares of Series A Preferred Stock surrendered for conversion shall
no longer be deemed to be outstanding and all rights of a holder of shares of
the Series A Preferred Stock with respect thereto shall immediately terminate
except the right to receive the Common Stock and other amounts, including
accumulated and unpaid dividends payable pursuant to this Section 5.

     (c)  Effect of Election.

               (i)    Upon delivery to the Corporation by a holder of shares of
the Series A Preferred Stock of a notice of election to convert, the right of
the Corporation to redeem the shares of Series A Preferred Stock which are to be
converted shall terminate, regardless of whether a notice of redemption has been
issued.


                                      -6-

 
                   (ii)   From and after the date of delivery of a notice of
     election to convert, shares of Series A Preferred Stock to be converted
     shall participate equally and ratably with the holders of shares of Common
     Stock in all dividends paid on the Common Stock as if such shares of Series
     A Preferred Stock had been converted to shares of Common Stock at the time
     of such delivery.

          (d) Issuance of Shares.

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

                   (ii)   Prior to the delivery of any securities which the
     Corporation shall be obligated to deliver upon conversion of shares of
     Series A Preferred Stock, the Corporation shall comply with all applicable
     federal and state laws and regulations, and all rules of the AMEX (or such
     other national securities exchange upon which the Common Stock is listed)
     which require action to be taken by the Corporation, and the Corporation
     shall use its reasonable commercial efforts to assist the holders of shares
     of the Series A Preferred Stock in complying with any such laws,
     regulations and rules. If the issuance of the number of shares of Common
     Stock to be issued pursuant to the conversion of shares of Series A
     Preferred Stock would require the prior approval of the stockholders of the
     Corporation in accordance with the rules of the AMEX (or, if the Common
     Stock is not then listed on the AMEX, such other national securities
     exchange upon which the Common Stock is listed), then the Corporation shall
     only be obligated to issue such number of shares of Common Stock as would
     not require such stockholder approval, and in lieu of issuance of the
     balance of such number of shares of Common Stock otherwise issuable to the
     holders of shares of the Series A Preferred Stock, the Corporation shall
     pay the holders of shares of the Series A Preferred Stock an amount in cash
     equal to the product of (x) the amount of such balance of shares otherwise
     issuable to the holders of shares of the Series A Preferred Stock and (y)
     the greater of the Market Price (determined as of the Conversion Date) of
     the Common Stock and (if applicable) the Non-Consensual Tender Offer Price.
     It is understood that as long as the Common Stock remains listed on the
     AMEX, the Corporation shall only be obligated to issue 854,582 (as
     presently constituted and subject to subsequent adjustments for stock
     splits, dividends, reverse stock split and the like) shares of Common Stock
     pursuant to the limitations set forth in the preceding sentence, except to
     the extent such limitations are not applicable.

          (e) Taxes on Conversion. The Corporation will pay any and all
documentary stamp or similar issue or transfer taxes payable in respect of the
issue or delivery of shares of Common Stock on conversion of any part of the
principal amount of shares of Series A Preferred Stock pursuant hereto; provided
                                                                        --------
that the Corporation shall not be required to pay any tax which may be payable
in respect of any transfer involved in the issue or delivery of shares of Common
Stock in a name other than that of the holder of shares of the Series A
Preferred Stock to be 


                                      -7-

 
converted and no such issue or delivery shall be made unless and until the
person requesting such issue or delivery has paid to the Corporation the amount
of any such tax or has established, to the satisfaction of the Corporation, that
such tax has been paid.

              (f) No Fractions of Common Stock to Be Issued. In connection with
the conversion of shares of Series A Preferred Stock all such shares surrendered
by the holder thereof (of any Affiliate of such holder) shall be aggregated and
no fractions of shares of Common Stock shall be issued upon conversion of such
shares, but in lieu thereof the Corporation shall pay a cash adjustment in
respect of such fractional interest in an amount equal to such fractional
interest multiplied by the Market Price determined as of the Conversion Date.

     6.  Anti-Dilution. Except as otherwise provided in Section 6(n) below, the
         -------------
Conversion Price shall be subject to adjustment from time to time as set forth
in this Section 6.

              (a) Stock Dividends, Subdivisions and Combinations. If and
whenever the Corporation subsequent to the Original Issuance Date:

                      (i)   declares a dividend upon, or makes any distribution
     in respect of, any of its capital stock, payable in shares of Common Stock,
     Convertible Securities or Stock Purchase Rights, or

                      (ii)  subdivides its outstanding shares of Common Stock
     into a larger number of shares of Common Stock, or

                      (iii) combines its outstanding shares of Common Stock into
     a smaller number of shares of Common Stock,

then the Conversion Price shall be adjusted to that price determined by
multiplying the Conversion Price in effect immediately prior to such event by a
fraction (A) the numerator of which shall be the total number of outstanding
shares of Common Stock immediately prior to such event, and (B) the denominator
of which shall be the total number of outstanding shares of Common Stock
immediately after such event, treating as outstanding all shares of Common Stock
issuable upon conversions or exchanges of such Convertible Securities and
exercises of such Stock Purchase Rights.

              (b) Issuance of Additional Shares of Common Stock. If and whenever
the Corporation subsequent to the date hereof shall issue or sell any shares of
Common Stock (except as otherwise provided in the last paragraph of this Section
6(b)), for a consideration less than the greater of (x) the Conversion Price and
(y) the Market Price per share (determined, in each case, as of the date
specified in the next succeeding paragraph), the Conversion Price upon each such
issuance or sale shall be adjusted to the lower of the prices calculated
pursuant to the following clauses (i) and (ii) of this Section 6(b) and shall be
determined by:

                      (i)   DIVIDING (A) an amount equal to the sum of (1) the
     number of shares of Common Stock outstanding immediately prior to such
     issue or sale multiplied by the Conversion Price in effect as of the date
     specified in the next succeeding paragraph plus 


                                      -8-

 
     (2) the aggregate consideration, if any, received by the Corporation upon
     such issue or sale, by (B) the total number of shares of Common Stock
     outstanding immediately after such issue or sale; and

                      (ii)  MULTIPLYING the Conversion Price in effect as of the
     date specified in the next succeeding paragraph by a fraction the numerator
     of which is (A) the sum of (1) the number of shares of Common Stock
     outstanding immediately prior to such issue or sale multiplied by the
     Market Price per share of Common Stock immediately prior to such issue or
     sale plus (2) the aggregate consideration, if any, received by the
     Corporation upon such issue or sale, divided by (B) the total number of
     shares of Common Stock outstanding immediately after such issue or sale,
     and the denominator of which is the Market Price per share of Common Stock
     immediately prior to such issue or sale.

          For purposes of this Section 6(b), the date as of which the Conversion
Price and the date as of which the Market Price shall be determined shall be the
earlier of (i) the date on which the Corporation shall enter into a firm
contract for the issuance of such shares of Common Stock and (ii) the date of
actual issuance of such shares of Common Stock.

          No adjustment of the Conversion Price shall be made under this Section
6(b) upon the issuance of any shares of Common Stock which are (i) distributed
to holders of Common Stock pursuant to a stock dividend or subdivision for which
an adjustment is provided under Section 6(a) or (ii) issued pursuant to the
exercise of any Stock Purchase Rights or pursuant to the conversion or exchange
of any Convertible Securities to the extent that an adjustment shall previously
have been made upon the issuance of such Stock Purchase Rights or Convertible
Securities pursuant to Sections 6(a), (c) or (d).

          (c) Issuance of Stock Purchase Rights. If and whenever the Corporation
subsequent to the date hereof shall issue or sell any Stock Purchase Rights and
the consideration per share for which shares of Common Stock may at any time
thereafter be issuable upon exercise thereof (or, in the case of Stock Purchase
Rights exercisable for the purchase of Convertible Securities, upon the
subsequent conversion or exchange of such Convertible Securities) shall be less
than the greater of (x) the Conversion Price and (y) the Market Price per share
(determined, in each case, as of the date specified in the next succeeding
paragraph), the Conversion Price upon each such issuance or sale shall be
adjusted as provided in Section 6(b) on the basis that the maximum number of
shares of Common Stock ever issuable upon exercise of such Stock Purchase Rights
(or upon conversion or exchange of such Convertible Securities following such
exercise) shall be deemed to have been issued as of the date of the
determination of the Conversion Price or the Market Price, as applicable,
specified in the next succeeding paragraph. No adjustment of the Conversion
Price shall be made under Section 6(b) upon the issuance of any shares of Common
Stock which are issued pursuant to the exercise, conversion or exchange of any
Stock Purchase Rights if any adjustment shall previously have been made upon the
issuance of any such Stock Purchase Rights as herein provided.

          For the purposes of this Section 6(c), the date as of which the
Conversion Price and the date as of which the Market Price shall be determined
shall be the earlier of (i) the date 


                                      -9-

 
on which the Corporation shall enter into a firm contract for the issuance of
such Stock Purchase Rights and (ii) the date of actual issuance of such Stock
Purchase Rights.

              (d) Issuance of Convertible Securities. If and whenever the
Corporation subsequent to the date hereof shall issue or sell any Convertible
Securities (except as otherwise provided in the last paragraph of this Section
6(d)) and the consideration per share for which shares of Common Stock may at
any time thereafter be issuable pursuant to the terms of such Convertible
Securities shall be less than the greater of (x) the Conversion Price and (y)
the Market Price per share (determined, in each case, as of the date specified
in the next succeeding paragraph), the Conversion Price upon each such issuance
or sale shall be adjusted as provided in Section 6(b) on the basis that the
maximum number of shares of Common Stock ever necessary to effect the conversion
or exchange of all such Convertible Securities shall be deemed to have been
issued as of the date of the determination of the Conversion Price or the Market
Price, as applicable, specified in the next succeeding paragraph.

              For the purposes of this Section 6(d), the date as of which the
Conversion Price and the date as of which the Market Price shall be determined
shall be the earlier of (i) the date on which the Corporation shall enter into a
firm contract for the issuance of such Convertible Securities and (ii) the date
of actual issuance of such Convertible Securities.

              No adjustment of the Conversion Price shall be made under this
Section 6(d) upon the issuance of any Convertible Securities which are issued
pursuant to the exercise of any Stock Purchase Rights to the extent that an
adjustment shall previously have been made upon the issuance of such Stock
Purchase Rights pursuant to Section 6(c).

              (e) Minimum Adjustment. If any adjustment of the Conversion Price
pursuant to this Section 6 shall result in an adjustment of less than $.0001, no
such adjustment shall be made, but any such lesser adjustment shall be carried
forward and shall be made at the time and together with the next subsequent
adjustment which, together with any adjustments so carried forward, shall amount
to $.0001; provided that upon any adjustment of the Conversion Price resulting
           --------
from (i) the declaration of a dividend upon, or the making of any distribution
in respect of, any stock of the Corporation payable in Common Stock, Stock
Purchase Rights or Convertible Securities or (ii) the reclassification by
subdivision, combination or otherwise, of the Common Stock into a greater or
smaller number of shares, the foregoing figure of $.0001 per share (or such
figure as last adjusted) shall be proportionately adjusted, and provided,
further, that upon the conversion of shares of Series A Preferred Stock, the
Corporation shall make all necessary adjustments (to the nearest .0001 of a
cent) not theretofore made to the Conversion Price up to and including the date
upon which shares of Series A Preferred Stock are converted.

              (f) Readjustment of Conversion Price. Upon each change in (i) the
purchase price payable for any Stock Purchase Rights or Convertible Securities
referred to in Section 6(c) or (d), (ii) the consideration, if any, payable upon
exercise of such Stock Purchase Rights or upon the conversion or exchange of
such Convertible Securities or (iii) the number of shares of Common Stock
issuable upon the exercise of such Stock Purchase Rights or the rate at which
such Convertible Securities are convertible into or exchangeable for shares of
Common Stock, the


                                     -10-

 
Conversion Price in effect at the time of such event shall forthwith be
readjusted to the Conversion Price which would have been in effect at such time
had such Stock Purchase Rights or Convertible Securities provided for such
changed purchase price, consideration, number of shares of Common Stock so
issuable or conversion rate, as the case may be, at the time initially granted,
issued or sold. On the expiration of any Stock Purchase Rights not exercised or
of any right to convert or exchange under any Convertible Securities not
exercised, the Conversion Price then in effect shall forthwith be increased to
the Conversion Price which would have been in effect at the time of such
expiration had such Stock Purchase Rights or Convertible Securities never been
issued. No readjustment of the Conversion Price pursuant to this Section 6(f)
shall (i) increase the Conversion Price by an amount in excess of the adjustment
originally made to the Conversion Price in respect of the issue, sale or grant
of the applicable Stock Purchase Rights or Convertible Securities or (ii)
require any adjustment to the amount paid or number of shares of Common Stock
received by any Person upon any conversion of shares of Series A Preferred Stock
prior to the date upon which such readjustment to the Conversion Price shall
occur.

              (g) Reorganization, Reclassification or Recapitalization of the
Corporation. If and whenever subsequent to the date hereof the Corporation shall
effect (i) any reorganization or reclassification or recapitalization of the
capital stock of the Corporation (other than in the cases referred to in Section
6(a)), (ii) any consolidation or merger of the Corporation with or into another
Person, (iii) the sale, transfer or other disposition of the property, assets or
business of the Corporation as an entirety or substantially as an entirety or
(iv) any other transaction (or any other event shall occur) as a result of which
holders of Common Stock become entitled to receive any shares of stock or other
securities and/or property (including, without limitation, cash, but excluding
any cash dividend that is paid out of the earnings or surplus of the Corporation
legally available therefor) with respect to or in exchange for the Common Stock
of the Corporation, there shall thereafter be deliverable upon the conversion of
shares of Series A Preferred Stock or any portion thereof (in lieu of or in
addition to the Common Stock theretofore deliverable, as appropriate) the
highest number of shares of stock or other securities and/or the greatest amount
of property (including, without limitation, cash) to which the holder of the
number of shares of Common Stock which would otherwise have been deliverable
upon the conversion of shares of Series A Preferred Stock or any portion thereof
at the time would have been entitled upon such reorganization or
reclassification or recapitalization of capital stock, consolidation, merger,
sale, transfer, disposition or other transaction or upon the occurrence of such
other event, and at the same aggregate Conversion Price.

              Prior to and as a condition of the consummation of any transaction
or event described in the preceding sentence, the Corporation shall make
equitable, written adjustments in the application of the provisions herein set
forth satisfactory to the Requisite Series A Stockholders so that the provisions
set forth herein shall thereafter be applicable, as nearly as possible, in
relation to any shares of stock or other securities or other property thereafter
deliverable upon conversion of shares of Series A Preferred Stock. Any such
adjustment shall be made by and set forth in an agreement of the Corporation
and/or the successor entity, as applicable, for the benefit of and in form and
substance acceptable to the Requisite Series A Stockholders, which agreement
shall bind each such entity and shall be accompanied by a favorable opinion of
the regular outside counsel to the Corporation (or such other firm as is


                                     -11-

 
reasonably acceptable to the Requisite Series A Stockholders) as to the
enforceability of such agreement and as to such other matters as such holders
may reasonably request.

              References in this Certificate of Vote of Directors Establishing a
Class or Series of Stock to shares of Common Stock issuable upon conversion of
shares of Series A Preferred Stock shall be deemed to include shares of Common
Stock and shares (other than Common Stock) and any other securities of the
Corporation or of any other Person which the holders of shares of Series A
Preferred Stock at any time shall be entitled to receive upon the conversion or
partial conversion of shares of Series A Preferred Stock, in lieu of or in
addition to Common Stock, or which at any time shall be issuable or shall have
been issued in exchange for or in replacement of Common Stock (or such other
shares or securities).

              (h) Other Dilutive Events. If any other transaction or event
(other than those explicitly referred to in this Section 6), including, without
limitation, distributions of property or assets of the Corporation or its
affiliates to Persons other than holders of Common Stock, shall occur as to
which the other provisions of this Section 6 are not strictly applicable but the
failure to make any adjustment to the Conversion Price or to any of the other
terms of the shares of Series A Preferred Stock would not fairly protect the
conversion rights and other rights represented by shares of Series A Preferred
Stock in accordance with the essential intent and principles hereof, then, and
as a condition to the consummation of any such transaction or event, and in each
such case, the Corporation shall appoint a firm of independent certified public
accountants of recognized national standing (which may be the regular auditors
of the Corporation), which shall give its opinion as to the adjustment, if any,
on a basis consistent with the essential intent and principles established in
this Section 6, necessary to preserve, without dilution, the rights represented
by the shares of Series A Preferred Stock. The certificate of any such firm of
accountants shall be conclusive evidence of the correctness of any computation
made under this Section 6. The Corporation shall pay the fees and expenses of
such firm of accountants in connection with any such opinion. Upon receipt of
such opinion, the Corporation will promptly mail a copy thereof to the holders
of the shares of Series A Preferred Stock and shall make the adjustments
described therein.

              (i) Determination of Consideration. For purposes of this Section
6, the consideration received or receivable by the Corporation for the issuance,
sale, grant or assumption of shares of Common Stock, Stock Purchase Rights or
Convertible Securities, irrespective of the accounting treatment of such
consideration, shall be valued and determined as follows:

                        (i)  Cash Payment. In the case of cash, the net amount
     received by the Corporation after deduction of any accrued interest or
     dividends, any expenses paid or incurred and any underwriting commissions
     or concessions paid or allowed by the Corporation in connection with such
     issue or sale.

                        (ii) Non-Cash Payment. In the case of consideration
     other than cash, the Fair Value thereof or, if less, in the case of any
     security, the Market Price of such 


                                     -12-

 
security, if applicable (in any case as of the date immediately preceding the
issuance, sale or grant in question).

          (iii)  Certain Allocations. If shares of Common Stock, Stock Purchase
Rights and/or Convertible Securities are issued or sold together with other
securities or other assets of the Corporation for a consideration which covers
more than one of the foregoing categories of securities and assets, the
consideration received or receivable (computed as provided in clauses (i) and
(ii) of this Section 6(i)) shall be allocable to such shares of Common Stock,
Stock Purchase Rights and/or Convertible Securities as reasonably determined in
good faith by the Board of Directors of the Corporation (provided such
                                                         --------
allocation is set forth in a written resolution and a certified copy thereof is
furnished to the holders of the shares of Series A Preferred Stock promptly (but
in any event within 10 days) following its adoption).

          (iv)   Dividends in Securities. If the Corporation shall declare a
dividend or make any other distribution upon any stock of the Corporation
payable in shares of Common Stock, Convertible Securities or Stock Purchase
Rights, such shares of Common Stock, Convertible Securities or Stock Purchase
Rights, as the case may be, issuable in payment of such dividend or distribution
shall be deemed to have been issued or sold without consideration.

          (v)    Stock Purchase Rights and Convertible Securities. The
consideration for which shares of Common Stock shall be deemed to be issued upon
the issuance or sale of any Stock Purchase Rights or Convertible Securities
shall be determined by dividing (A) the total consideration, if any, received by
the Corporation as consideration for the Stock Purchase Rights or the
Convertible Securities, as the case may be, plus the minimum aggregate amount of
additional consideration, if any, ever payable to the Corporation upon the
exercise of such Stock Purchase Rights or upon the conversion or exchange of
such Convertible Securities, as the case may be, in each case after deducting
any accrued interest or dividends, any expenses paid or incurred and any
underwriting commissions or concessions paid or allowed by the Corporation in
connection with such issue or sale; by (B) the maximum number of shares of
Common Stock ever issuable upon the exercise of such Stock Purchase Rights or
upon the conversion or exchange of such Convertible Securities.

          (vi)   Merger, Consolidation or Sale of Assets. If any shares of
Common Stock, Convertible Securities or Stock Purchase Rights are issued in
connection with any merger or consolidation of which the Corporation is the
surviving corporation, the amount of consideration therefor shall be deemed to
be the Fair Value of such portion of the assets and business of the non-
surviving corporation as shall be attributable to such Common Stock, Convertible
Securities or Stock Purchase Rights, as the case may be. In the event of (a) any
merger or consolidation of which the Corporation is not the surviving
corporation or (b) the sale, transfer or other disposition of the property,
assets or business of the Corporation as an entirety or substantially as an
entirety for stock or other securities of any other Person, the Corporation
shall be deemed to have issued the number 


                                     -13-

 
     of shares of its Common Stock for stock or securities of the surviving
     corporation or such other Person computed on the basis of the actual
     exchange ratio on which the transaction was predicated and for a
     consideration equal to the Fair Value on the date of such transaction of
     such stock or securities of the surviving corporation or such other Person,
     and if any such calculation results in adjustment of the Conversion Price,
     the determination of the number of shares of Common Stock issuable upon
     conversion of shares of Series A Preferred Stock immediately prior to such
     merger, consolidation or sale, for the purposes of Section 6(g), shall be
     made after giving effect to such adjustment of the Conversion Price.

                  (j) Record Date. If the Corporation shall take a record of the
holders of the Common Stock for the purpose of entitling them (i) to receive a
dividend or other distribution payable in Common Stock, Convertible Securities
or Stock Purchase Rights or (ii) to subscribe for or purchase Common Stock,
Convertible Securities or Stock Purchase Rights, then all references in this
Section 6 to the date of the issue or sale of the shares of Common Stock deemed
to have been issued or sold upon the declaration of such dividend or the making
of such other distribution or the date of the granting of such right of
subscription or purchase, as the case may be, shall be deemed to be references
to such record date.

                  (k) Shares Outstanding. The number of shares of Common Stock
deemed to be outstanding at any given time shall not include shares of Common
Stock held by the Corporation or any Subsidiary of the Corporation.

                  (l) Maximum Conversion Price. At no time shall the Conversion
Price exceed the initial Conversion Price set forth in Section 5(a) hereof
except as a result of an adjustment thereto pursuant to Section 6(a)(iii) or
6(g).

                  (m) Application. All subdivisions of this Section 6 are
intended to operate independently of one another. If a transaction or an event
occurs that requires the application of more than one subdivision, all
applicable subdivisions shall be given independent effect.

                  (n) No Adjustments Under Certain Circumstances. Anything
herein to the contrary notwithstanding, no adjustment to the Conversion Price
shall be made in the case of:

                           (i)   any issuance of shares of Common Stock (or
     Other Securities) upon the conversion of shares of Series A Preferred Stock
     in accordance with the terms of this Certificate of Vote of Directors
     Establishing a Class or Series of Stock; or

                           (ii)  any issuance of the Senior Notes or shares of
     Common Stock (or Other Securities) upon the exercise in whole or part of
     principal, premium (if any) or interest in the Senior Notes; or

                           (iii) (A) the granting by the Corporation of Stock
     Purchase Rights to the officers, employees, directors and consultants of
     the Corporation or any Subsidiary pursuant to any qualified or non-
     qualified stock option plan or agreement, stock purchase plan or agreement,
     stock restriction agreement, employee stock ownership plan (ESOP),


                                     -14-

 
     consulting agreement, or such other options, issuance, arrangements,
     agreements or plans approved by the Board of Directors of the Corporation
     and (B) the issuance of shares of Common Stock pursuant to the exercise of
     such Stock Purchase Rights; provided that the aggregate number of shares of
                                 -------- 
     Common Stock to which this clause (ii) shall apply shall not exceed
     1,061,029 (such number to be appropriately adjusted for stock splits, stock
     dividends, combinations and similar events); or

                        (iv)  up to 427,292 shares of Common Stock issued after
     March 31, 1998 (such number to be appropriately adjusted for stock splits,
     stock dividends, combinations and similar events) (w) solely in
     consideration for the acquisition (whether by merger or otherwise) by the
     Corporation of all or substantially all of the capital stock or assets of
     any other entity or business organization, (x) solely in consideration for
     the grant by or to the Corporation of marketing rights, distribution
     rights, license rights or similar rights granted by or to the Corporation
     in consideration of the exchange of proprietary technology, whether of the
     Corporation or any other entity, (y) to equipment leasing companies in
     connection with any equipment leasing arrangements to which the Corporation
     is a party or (z) for working capital or other corporate purposes; provided
     that in the case of each of clauses (w), (x), (y) or (z), such issuance has
     been approved by a majority of the members of the Board of Directors.

           (o)  Waiver. In the event that the Requisite Series A Stockholders
consent in writing to limit, or waive in its entirety, any anti-dilution
adjustment to which the holders of shares of Series A Preferred Stock would
otherwise be entitled hereunder, the Corporation shall not be required to make
any adjustment whatsoever with respect to shares of Series A Preferred Stock in
excess of such limit or at all, as the terms of such consent may dictate.

           (p)  Adjustments to Conversion Price. As promptly as practicable (but
in any event not later than five days) after the occurrence of any event
requiring any adjustment under this Section 6 to the Conversion Price (or to the
number or kind of securities or other property deliverable upon the conversion
of shares of Series A Preferred Stock), the Corporation shall, at its expense,
mail to the holders of shares of Series A Preferred Stock either (i) an
Officers' Certificate or (ii) a certificate signed by a firm of independent
certified public accountants of recognized national standing (which may be the
regular auditors of the Corporation), setting forth in reasonable detail the
events requiring the adjustment and the method by which such adjustment was
calculated and specifying the adjusted Conversion Price and the number of shares
of Common Stock issuable upon conversion of shares of Series A Preferred Stock
after giving effect to such adjustment. The certificate of any such firm of
accountants shall be conclusive evidence of the correctness of any computation
made under this Section 6.

           (q)  Extraordinary Corporate Events. If and whenever the Corporation
subsequent to the date hereof shall propose to (i) pay any dividend payable in
stock to the holders of shares of Common Stock or to make any other distribution
to the holders of shares of Common Stock, (ii) offer to the holders of shares of
Common Stock rights to subscribe for or purchase any additional shares of any
class of stock or any other rights or options or (iii) effect any
reclassification of the Common Stock (other than a reclassification involving
merely the


                                     -15-

 
subdivision or combination of outstanding shares of Common Stock), (iv) engage
in any reorganization or recapitalization or any consolidation or merger (other
than a merger in which no distribution of securities or other property is to be
made to holders of shares of Common Stock), (v) consummate any sale, transfer or
other disposition of its property, assets and business as an entirety or
substantially as an entirety, (vi) effect any other transaction which might
require an adjustment to the Conversion Price (or to the number or kind of
securities or other property deliverable upon the conversion of shares of Series
A Preferred Stock), including, without limitation, any transaction of the kind
described in Section 6(g) or (vii) commence or effect a Liquidation, then, in
each such case, the Corporation shall mail to the holders of shares of Series A
Preferred Stock an Officers' Certificate giving notice of such proposed action,
specifying (A) the date on which the stock transfer books of the Corporation
shall close, or a record shall be taken, for determining the holders of Common
Stock entitled to receive such stock dividends or other distribution or such
rights or options, or the date on which such reclassification, reorganization,
recapitalization, consolidation, merger, sale, transfer, other disposition,
transaction, liquidation, dissolution or winding up shall take place or
commence, as the case may be, and (B) the date as of which it is expected that
holders of Common Stock of record shall be entitled to receive securities or
other property deliverable upon such action, if any such date is to be fixed.
Such Officers' Certificate shall be mailed in the case of any action covered by
clause (i) or (ii) above, at least 30 days prior to the record date for
determining holders of Common Stock for purposes of receiving such payment or
offer, and, in any other case, at least 30 days prior to the date upon which
such action takes place and 20 days prior to any record date to determine
holders of Common Stock entitled to receive such securities or other property.

                  (r) Effect of Failure. Failure to give any certificate or
notice, or any defect in any certificate or notice required under this Section 6
shall not affect the legality or validity of the adjustment of the Conversion
Price or the number of shares of Common Stock issuable upon conversion of shares
of Series A Preferred Stock.

                  (s) Anti-dilution Provisions in Other Securities. If the
Corporation issues any Stock Purchase Rights or Convertible Securities or other
securities containing provisions protecting the holder or holders thereof
against dilution in any manner more favorable to such holder or holders thereof
than those set forth in shares of Series A Preferred Stock, such provisions (or
any more favorable portion thereof) shall be deemed to be incorporated herein as
if fully set forth in shares of Series A Preferred Stock and, to the extent
inconsistent with any provision of shares of Series A Preferred Stock, shall be
deemed to be substituted therefor.

     7.   Voting Rights. The holders of shares of Series A Preferred Stock shall
