shall be subject to the doctrine of "corporate opportunities" only insofar as it
applies to business opportunities in which this Corporation has expressed an
interest as determined from time to time by this Corporation's Board of
Directors as evidenced by resolutions appearing in the Corporation's minutes.
Once such areas of interest are delineated, all such business opportunities
within such areas of interest which come to the attention of the officers,
directors, and other members of management of this Corporation shall be offered
first to the Corporation. In the event the Corporation declines to pursue any or
all such business opportunities, the officers, directors and other members. of
management of this Corporation shall be free to engage in such areas of interest
on their own and this doctrine shall not limit the right of any officer,
director or other member of management of this Corporation (other than an
officer, director, or member of management) from any duties which he may have to
this Corporation.

                                  ARTICLE IX

                             DIRECTORS AND OTHERS
                             --------------------

     1.  To the full extent permitted by the Colorado Corporation Code, the
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending 

                                       4

 
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative and whether formal or informal (other than an action by or in
the right of the Corporation) by reason of the fact that he is or was a
Director, Officer, employee, fiduciary or agent of the Corporation, or is or was
serving at the request of the Corporation as a Director, Officer, employee,
fiduciary or agent of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding if
he conducted himself in good faith and in a manner he reasonably believed to be
in or not opposed to the best interests of the Corporation, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, or conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself create a presumption that the person did
not act in good faith and in a manner which he reasonably believed to be in or
not opposed to the best interests of the Corporation and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

     2.  The Corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor by
reason of the fact that he is or was a Director, Officer, employee, fiduciary or
agent of the Corporation, or is or was serving at the request of the Corporation
as a Director, Officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the Corporation and except that no indemnification shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable for negligence or misconduct in the performance of
his duty to the Corporation unless and only to the extent that the court in
which such action or suit was brought shall determine upon application that,
despite the adjudication of liability but in view of all circumstances of the
case, such person is fairly and reasonably entitled to indemnity for such
expenses which such court shall deem proper.

                                       5

 
     3.  To the extent that a Director, Officer, employee, fiduciary or agent of
the Corporation has been wholly successful on the merits or otherwise in defense
of any action, suit or proceeding referred to in paragraphs 1 and 2 of this
Article, or in defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.

     4.  Any indemnification under paragraphs 1 and 2 of this Article (unless
ordered by a court) shall be made by the Corporation only as authorized in the
specific case upon a determination that indemnification of the Director,
Officer, employee, fiduciary or agent is proper in the circumstances because he
has met the applicable standard of conduct set forth in paragraphs 1 and 2. Such
determination shall be made (1) by the Board of Directors by a majority vote of
a quorum consisting of Directors who were not parties to such action, suit or
pending, or (2) if such a quorum is not attainable, or, even if obtainable a
quorum of disinterested Directors so directs, by independent legal counsel in a
written opinion, or (3) by the stockholders.

     5.  Expenses (including attorneys' fees) incurred in defending a civil or
criminal action, suit or pending may be paid by the Corporation in advance of
the final disposition of such action, suit or proceeding as authorized in the
manner provided in paragraph 4 of this Article upon receipt of an undertaking by
or on behalf of the Director, Officer, employee, fiduciary or agent to repay
such amount unless it shall ultimately be determined that he is entitled to be
indemnified by the Corporation as authorized in this section.

     6.  The Corporation shall have power to purchase and maintain insurance on
behalf of any person who is or was a Director, Officer, employee, fiduciary or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise against any
liability asserted against him and incurred by him in any such capacity or
arising out of his status as such, whether or not the Corporation would have the
power to indemnify him against such liability under the provisions of this
section.

                                       6

 
     7.  In addition to the foregoing, the Corporation shall have the power to
indemnify current or former directors, officers, employees and agents to the
fullest extent provided by the laws of the State of Colorado.

a class of preferred stock consisting of 500,000 shares to be known as the 10%
Preferred Stock (the "10% Preferred Stock"). The 10% Preferred Stock shall have
a stated value of $10.00 per share. The preferences, limitations and relative
rights of the 10% Preferred Stock shall be as provided in this Section 5.

          A.   Voting Rights.

               (1)  Each outstanding share of the 10% Preferred Stock is
          entitled to one vote on each matter submitted to a vote of
          shareholders. The holders of the 10% Preferred Stock shall be entitled
          to vote on all matters voted upon by the holders of the Corporation's
          Common Stock. Unless otherwise required by law, the holders of the
          Common Stock and the holders of the 10% Preferred Stock shall vote as
          a single class on all matters submitted to a vote of shareholders.

               (2)  The holders of the 10% Preferred Stock shall not be entitled
          to any rights of cumulative voting with respect to their shares.

          B.   Preemptive Rights. No holder of the 10% Preferred Stock shall
     have any preemptive or similar right to acquire any additional unissued or
     treasury shares of stock or securities of any class or rights, warrants or
     options to purchase stock or scrip or securities in any kind, including
     shares or securities convertible into shares or carrying stock purchase
     warrants or privileges.

          C.   Dividends.

               (1)  Dividends shall accrue on the 10% Preferred Stock at the
          rate of ten percent (10%) per annum on the stated value of the 10%
          Preferred Stock and shall be paid quarterly on the first of each
          January, April, July and October, beginning July 1, 1998, to the
          record holder thereof on the 15th of the previous month, subject to
          the limitations contained within the statutes of the State of
          Colorado. Dividends not paid in any quarter shall accumulate until
          paid, with interest on the unpaid balance, if any, accruing simple
          interest at the rate stated above. Subject to the foregoing
          limitations, dividends may be paid out of any funds legally available
          for such purpose.

               (2)  Dividends on the 10% Preferred Stock shall be declared and
          paid before dividends of any kind may be declared and paid on the
          Common Stock or any inferior class or series of stock and before
          distribution or any liquidation or distribution of any kind may be
          made upon the issued and outstanding Common Stock or any inferior
          class of stock.

               (3)  Upon any redemption or conversion of the 10% Preferred Stock
          pursuant to paragraphs G and H below, the Corporation shall pay all
          accrued but unpaid dividends on the 10% Preferred Stock called for
          redemption or converted, as the case may be. The Corporation may pay
          such accrued but unpaid dividends either (i) in cash or (ii) by
          issuing shares of Common Stock at a price per share equal to the
          lesser of (a) $10.00 or (b) if a redemption or a conversion occurring
          with respect to shares of the 10% Preferred Stock for which the
          Corporation has given a Notice of Redemption (as that term is defined
          in subparagraph G(2), below), the Average Per Share Closing Bid Price
          (as defined below) for the five trading days immediately preceding the
          date on which the Notice of Redemption was first given to the holders
          of the 10% Preferred Stock called for redemption, or, if a conversion
          occurring with respect to shares of the 10% Preferred

                                       11

 
          Stock for which the Corporation has not given a Notice of Redemption,
          the Average Per Share Closing Bid Price for the five trading days
          immediately preceding the date on which the Conversion Notice (as that
          term is defined in subparagraph H(3), below) was first given to the
          Corporation.

               (4)  Upon payment by the Corporation of dividends on the basis
          described in subparagraphs C(1)-C(3), the holders of the 10% Preferred
          Stock shall have no further right to dividends and shall not
          participate in any manner in dividends declared and paid or other
          distributions on the Common Stock or any inferior class or series of
          stock.

          D.   Liquidation Preference. In the event of the liquidation,
     dissolution or winding up of the affairs of the Corporation, whether
     voluntary or involuntary, the holders of the 10% Preferred Stock shall be
     entitled to receive, after payment by the Corporation of its debts and
     liabilities, the stated value of all shares of the 10% Preferred Stock in
     cash plus any all accrued but unpaid dividends out of the assets of the
     Corporation before any payment shall be made or any assets distributed to
     the holders of the Common Stock or any other inferior class or series of
     stock. If sufficient assets are not available to pay all holders of the 10%
     Preferred Stock in full, the available assets shall be distributed to the
     holders of the 10% Preferred Stock on a pro rata basis. Except as provided
     in this paragraph D, the holders of the 10% Preferred Stock shall not be
     entitled to receive any other payments from the Corporation in the event of
     the liquidation, dissolution or winding up of the affairs of the
     Corporation.

          E.   Other Securities, Obligations.

               (1)  Subject to any limitations contained in these Articles of
          Incorporation, the Board of Directors of the Corporation reserves the
          right to establish additional classes and/or series of capital stock
          of the Corporation and to designate the preferences, limitations and
          relative rights of any such classes and/or series; provided, however,
          that no such class and/or series may have preferences, limitations and
          relative rights which are superior to or senior to the preferences,
          limitations and relative rights granted to the holders of the 10%
          Preferred Stock.

               (2)  At any time during which any shares of the 10% Preferred
          Stock are outstanding, the Corporation shall not incur any obligation
          or liability other than trade payables and other short-term
          indebtedness incurred in the ordinary course of business that is
          superior to or senior to the 10% Preferred Stock in any respects,
          including liquidation preferences.

          F.   Capital Reorganization. If the Corporation shall at any time
     hereafter subdivide or combine its outstanding shares of Common Stock,
     declare a dividend payable in Common Stock, or in case of any capital
     reorganization or reclassification of the shares of Common Stock of the
     Corporation, the number of shares and stated value of the 10% Preferred
     Stock shall be adjusted appropriately to allow the holders of the 10%
     Preferred Stock, as nearly as reasonably possible, to maintain (i) the
     aggregate stated value of their 10% Preferred Stock and (ii) their pro rata
     interest in the Corporation and in the Common Stock upon conversion of the
     10% Preferred Stock, that they had prior to any such subdivision,
     combination, stock dividend, reorganization or reclassification.

          G.   Redemption.

               (1)  The 10% Preferred Stock may be redeemed by the Corporation,
          in whole or in part, at any time for $10.00 per share (the "Redemption
          Price"). It is the Corporation's intent to use its best efforts to
          raise sufficient capital to both fund its operations and to permit it
          to redeem the 10% Preferred Stock as soon as is reasonably

                                       12

 
          possible. In addition, if the Corporation completes a public offering
          of its securities that raises net proceeds of at least $5,000,000 (the
          "Public Offering") within nine months from the date on which the
          initial closing of the offering of the 10% Preferred Stock occurs (the
          "Closing Date"), then the Corporation shall redeem all of the
          outstanding 10% Preferred Stock.

               (2)  The Corporation shall give not more than sixty (60) nor less
          than thirty (30) days notice (the "Notice of Redemption") of the date
          fixed for any redemption (as fixed, the "Redemption Date") of the 10%
          Preferred Stock by mailing the Notice of Redemption to the record
          holders of the 10% Preferred Stock to such holder's address as it
          appears on the records of the Corporation; provided, however, that the
          Corporation shall not be required to give notice of any redemption of
          the 10% Preferred Stock that occurs within nine months from the
          Closing Date.  In the case of a partial redemption of the 10%
          Preferred Stock, the shares to be redeemed shall be selected in any
          manner the Corporation may determine.  The Notice of Redemption shall
          be deemed given when it is deposited in the United States mail with
          sufficient postage affixed or when it is delivered to the record
          holder at such holder's address as it appears on the records of the
          Corporation.

               (3)  On the Redemption Date, all rights of the holders of the 10%
          Preferred Stock called for redemption shall cease and terminate with
          respect to such shares except (i) the right to receive the Redemption
          Price upon surrender of the certificates representing the shares of
          the 10% Preferred Stock called for redemption and (ii) the right to
          receive payment of all dividends with respect to the shares of 10%
          Preferred Stock called for redemption which are accrued but unpaid on
          the Redemption Date.

          H.   Conversion.

               (1)  If the 10% Preferred Stock is not redeemed within nine
          months from the Closing Date, each share of the outstanding 10%
          Preferred Stock shall become convertible, at the election of the
          holder thereof (the "Conversion Right"), into the number of shares of
          Common Stock of the Corporation equal to $10.00 divided by the lesser
          of (i) $10.00 or (ii) 80% of the Average Per Share Closing Bid Price
          of the Corporation's Common Stock as calculated pursuant to the next
          sentence The "Average Per Share Closing Bid Price" shall be (a) if the
          conversion occurs with respect to shares of the 10% Preferred Stock
          for which the Corporation has given a Notice of Redemption, the
          average per share closing bid price for the Corporation's Common Stock
          for the five trading days immediately preceding the date on which the
          Notice of Redemption was first given to the holders of the 10%
          Preferred Stock called for redemption or (b) if the conversion occurs
          with respect to shares of the 10% Preferred Stock for which the
          Corporation has not given a Notice of Redemption, the average closing
          bid price for the five trading days immediately preceding the date on
          which the holder gives the Conversion Notice (as that term is defined
          in subparagraph H(3), below) to the Corporation. The Closing Bid Price
          for the Common Stock at any date shall be (i) the Closing Bid Price of
          the Common Stock as reported in The Wall Street Journal (or, if not so
          reported, as otherwise reported by The Nasdaq Stock Market or, (ii) in
          the event that the Common Stock is listed on a stock exchange or on
          the Nasdaq National Market (or other national market), the Closing Bid
          Price shall be the closing price on the exchange or the Nasdaq
          National Market (or other national market), as the case may be, as
          reported in The Wall Street Journal (or, if not so reported, as
          otherwise reported by the stock exchange, Nasdaq or other national
          market). In the event that there is no reported Closing Bid Price or
          sale price, as the case may be, for a given day, the Closing Bid Price
          or sale price, as the case may be, for that day shall be deemed to be
          the Closing Bid Price

                                       13

 
          or sale price, as the case may be, for the first day preceding such
          day for which there was a reported Closing Bid Price or sale price, as
          the case may be.

               (2)  The Conversion Right shall expire and terminate five (5)
          days prior to the Redemption Date. In the case of a partial redemption
          of the 10% Preferred Stock, the Conversion Right shall so expire and
          terminate only with respect to the shares of the 10% Preferred Stock
          called for redemption.

               (3)  In order to exercise the Conversion Right, the holder of the
          10% Preferred Stock to be converted shall give written notice (the
          "Conversion Notice") to the Corporation at its principal office or, at
          the option of the Corporation, at the offices of a conversion agent
          which the Corporation may designate from time to time by giving
          written notice of such designation to the holders of the 10% Preferred
          Stock, that the holder elects to convert such shares.  The Conversion
          Notice shall be accompanied by the certificate or certificates
          representing the shares of the 10% Preferred Stock to be converted,
          duly endorsed to the Corporation.  The Conversion Notice shall be
          deemed given when it is deposited in the United States mail with
          sufficient postage affixed or when it is delivered to the Corporation
          at its principal office (or to the offices of such conversion agent,
          if one be designated).

               (4)  As soon as practicable after the receipt of the Conversion
          Notice and the certificates representing the shares of the 10%
          Preferred Stock to be converted, the Corporation shall issue and shall
          deliver to the record holder of the shares so surrendered for
          conversion by mail to the address of such record holder as it appears
          on the records of the Corporation, a certificate or certificates for
          the number of shares of Common Stock issuable upon conversion of the
          shares of the 10% Preferred Stock and a residual certificate for
          shares of the 10% Preferred Stock, if any, not converted.  Such
          conversion shall be deemed to have been effected on the date on which
          the Corporation (or the conversion agent, if one be designated), shall
          have received the Conversion Notice and the certificate or
          certificates representing shares of the 10% Preferred Stock to be
          converted, and the record holder shall be deemed to have become on
          such date the holder of record of the shares of Common Stock to be
          received upon conversion; provided, however, that any such surrender
          on any date when the stock transfer books of the Corporation shall be
          closed in accordance with the bylaws of the Corporation shall not be
          deemed to constitute the record holder as the holder of shares of
          Common Stock to be received upon conversion for any purpose until the
          close of business on the day succeeding the day on which such stock
          transfer books shall become open.

               (5)  The Corporation shall not be required to issue fractional
          shares of Common Stock upon conversion of shares of the 10% Preferred
          Stock.  If any fractional interest in a share of Common Stock would be
          deliverable upon conversion of any shares of the 10% Preferred Stock,
          the Corporation shall make an adjustment therefor in cash at the
          current market value thereof, computed on the basis determined by the
          Corporation in its sole discretion.

     ----------

                                    Thomas S. Plunkett
                                    Chief Financial Officer

                                       15

 
                                                                       EXHIBIT A

     6.   Designation of Preferred Stock.  The Corporation shall establish and
reserve for issuance from its 5,000,000 authorized shares of Preferred Stock a
class of convertible preferred stock consisting of 3,000 shares to be designated
as the 5% Preferred Stock (the "5% Preferred Stock").  The 5% Preferred Stock
shall have a stated value of the Liquidation Preference (as hereinafter
defined).  Except as otherwise expressly stated in this Section 6, all shares of
the 5% Preferred Stock shall be identical to the shares of 10% Preferred Stock,
and the holders of 5% Preferred Stock shall be entitled to the same preferences,
limitations and relative rights as the holders of 10% Preferred Stock.

          A.   Dividends.

               (1)  Holders of the 5% Preferred Stock shall be entitled to
          receive, out of funds legally available therefor, dividends at a rate
          equal to 5% (the "Dividend Rate") of the Liquidation Preference per
          share per annum (subject to appropriate adjustments in the event of
          any stock dividend, stock split, combination or other similar
          recapitalization affecting such shares), and no more, payable in
          accordance with the provisions of this Section 6. Notwithstanding the
          foregoing sentence of this Subsection A(1), in the event the
          Registration Statement (as hereinafter defined) is not declared
          effective by the Securities and Exchange Commission (the "Commission")
          within 90 days following the Initial Closing Date (as defined in that
          certain Securities Purchase Agreement (the "Securities Purchase
          Agreement"), dated as of May 22, 1998, among the Corporation, the
          purchasers named therein and West End Capital LLC), then the Dividend
          Rate shall increase to 18% until the Registration Statement is
          declared effective; provided, however, that if the Commission conducts
          a review of the Registration Statement, the Dividend Rate shall not
          increase unless it is not declared effective by the Commission within
          120 days following the Initial Closing Date, at which time the
          Dividend Rate shall increase to 18% until the Registration Statement
          is declared effective.

               (2)  At the election of the Corporation, each dividend on 5%
          Preferred Stock shall be paid either in shares of Common Stock or in
          cash on the Delivery Date (as defined in Subsection H(2)(a) of this
          Section 6) with respect to any shares of 5% Preferred Stock which are
          the subject of a Notice of Conversion (as defined in Subsection
          H(2)(a) of this Section 6). Dividends paid in shares of Common Stock
          shall be paid (based on an assumed value of $1,000 per share) in full
          shares only, with a cash payment equal to the value of any fractional
          shares. Each dividend paid in cash shall be mailed to the holders of
          record of the 5% Preferred Stock as their names and addresses appear
          on the share register of the Corporation or at the office of the
          transfer agent on the corresponding dividend payment date. Holders of
          5% Preferred Stock will receive written notification from the
          Corporation or the transfer agent if a dividend is paid in kind, which
          notification will specify the number of shares of Common Stock paid as
          a dividend and the recipient's aggregate holdings of Common Stock as
          of that dividend payment date and after giving effect to the dividend.
          All holders of shares of Common Stock issued as dividends shall be
          entitled to all of the rights and benefits relating to shares of
          Common Stock as set forth in the Corporation's Articles of
          Incorporation, as amended, and By-laws.

               (3)  Holders of the 5% Preferred Stock shall be entitled to
          payment of any dividends in preference and priority to any payment of
          any cash dividend on Common Stock or any other class or series of
          capital stock of the Corporation other than any other class or series
          of stock ranking senior ("Senior Preferred Stock") to the 5% Preferred
          Stock in respect of dividends, when and as declared by the Board of
          Directors of the Corporation. The rights of the holders of 5%
          Preferred Stock and 10% Preferred Stock to receive any dividends shall
          be equal in preference and priority. Dividends on the 5%

                                       16

 
          Preferred Stock shall accrue with respect to each share of the 5%
          Preferred Stock from the date on which such share is issued and
          outstanding and thereafter shall be deemed to accrue from day to day
          whether or not earned or declared and whether or not there exists
          profits, surplus or other funds legally available for the payment of
          dividends, and shall be cumulative so that if such dividends on the 5%
          Preferred Stock shall not have been paid, or declared and set apart
          for payment, the deficiency shall be fully paid or declared and set
          apart for payment before any dividend shall be paid or declared or set
          apart for any Common Stock or other class or series of capital stock
          ranking junior to the 5% Preferred Stock (such stock being
          collectively referred to herein as the "Junior Stock") and before any
          purchase or acquisition of any Junior Stock is made by the
          Corporation, except the repurchase of Junior Stock from employees of
          the Corporation upon termination of employment. At the earlier of: (1)
          the redemption or conversion of the 5% Preferred Stock or (2) the
          liquidation of the Corporation, any accrued but undeclared dividends
          shall be paid to the holders of record of outstanding shares of the 5%
          Preferred Stock in accordance with the provisions of this Section 6.
          No accumulation of dividends on the 5% Preferred Stock shall bear
          interest.

          B.   Liquidation, Dissolution or Winding Up.

               (1)  In the event of any voluntary or involuntary liquidation,
          dissolution or winding up of the Corporation, the holders of shares of
          the 5% Preferred Stock then outstanding shall be entitled to be paid
          out of the assets of the Corporation available for distribution to its
          stockholders, after and subject to the payment in full of all amounts
          required to be distributed to the holders of any Senior Preferred
          Stock ranking on liquidation prior and in preference to the Preferred
          Stock, but before any payment shall be made to the holders of Junior
          Stock by reason of their ownership thereof, an amount equal to $1,000
          per share of 5% Preferred Stock (the "Liquidation Preference") plus
          any accrued but unpaid dividends (whether or not declared).  The
          rights of the holders of 5% Preferred Stock and 10% Preferred Stock to
          receive any such distributions shall be equal in preference and
          priority.  If upon any such liquidation, dissolution or winding up of
          the Corporation the remaining assets of the Corporation available for
          distribution to its shareholders shall be insufficient to pay the
          holders of shares of the 5% Preferred Stock the full amount to which
          they shall be entitled, the holders of shares of the 5% Preferred
          Stock shall share ratably in any distribution of the remaining assets
          and funds of the Corporation in proportion to the respective amounts
          which would otherwise be payable in respect of the shares held by them
          upon such distribution if all amounts payable on or with respect to
          such shares were paid in full.

               (2)  After the payment of all preferential amounts required to be
          paid to the holders of the 5% Preferred Stock and the 10% Preferred
          Stock upon the dissolution, liquidation, or winding up of the
          Corporation, all of the remaining assets and funds of the Corporation
          available for distribution to its shareholders shall be distributed
          ratably among the holders of the 5% Preferred Stock and the Junior
          Stock, with each share of 5% Preferred Stock being deemed, for such
          purpose, to be equal to the number of shares of Common Stock,
          including fractions of a share, into which such share of 5% Preferred
          Stock is convertible immediately prior to the close of business on the
          business day fixed for such distribution.

          C.   Voting.

               (1)  Each holder of outstanding shares of 5% Preferred Stock
          shall be entitled, at each meeting of shareholders of the Corporation
          (and with respect to written consents of shareholders in lieu of
          meetings) with respect to any and all matters presented to the
          shareholders of the Corporation for their action or consideration, to
          the

                                       17

 
          number of votes equal to the number of whole shares of Common Stock
          into which the shares of 5% Preferred Stock held by such holder are
          convertible (as adjusted from time to time pursuant to Subsection H
          hereof) immediately after the close of business on the record date
          fixed for such meeting or the effective date of such written consent.
          Except as provided by law, by the provisions of Section J below, or by
          the provisions establishing any other series of preferred stock,
          holders of 5% Preferred Stock shall vote together with the holders
          Common Stock as a single class.

               (2)  The holders of the 5% Preferred Stock shall not be entitled
          to any rights of cumulative voting with respect to their shares.

          D.   Preemptive Rights.  No holder of Preferred Stock shall have any
     preemptive or similar right to acquire any additional unissued or treasury
     shares of stock or securities of any class or rights, warrants or options
     to purchase stock or scrip or securities in any kind, including shares or
     securities convertible into shares or carrying stock purchase warrants or
     privileges.

          E.   Other Securities.  Subject to any limitations contained in these
     Articles of Incorporation, the Board of Directors of the Corporation
     reserves the right to establish additional classes and/or series of capital
     stock of the Corporation and to designate the preferences, limitations and
     relative rights of any such classes and/or series; provided, however, that
     no such class and/or series may have preferences, limitations and relative
     rights which are superior to or senior to the preferences, limitations and
     relative rights granted to the holders of the 5% Preferred Stock.

          F.   Capital Reorganization.  If the Corporation shall at any time
     hereafter subdivide or combine its outstanding shares of Common Stock,
     declare a dividend payable in Common Stock, or in case of any capital
     reorganization or reclassification of the shares of Common Stock of the
     Corporation, the number of shares of the 5% Preferred Stock and the stated
     value of the 5% Preferred Stock shall be adjusted appropriately to allow
     the holders of the 5% Preferred Stock, as nearly as reasonably possible, to
     maintain (i) the aggregate stated value of the 5% Preferred Stock and (ii)
     their pro rata interest in the Corporation and in the Common Stock upon
     conversion of the 5% Preferred Stock, that each holder had prior to any
     such subdivision, combination, stock dividend, reorganization or
     reclassification.

          G.   Optional Redemption

               (1)  At any time within the 120 days following the Initial
          Closing Date, the Corporation may, at its option, redeem all or any
          portion of the shares of 5% Preferred Stock then outstanding upon not
          less than ten (10) days' notice at a redemption price per share equal
          to (A) the quotient of (i) the Liquidation Preference per share of 5%
          Preferred Stock plus all accrued but unpaid dividends on such shares
          of 5% Preferred Stock and (ii) the Conversion Price as if the 5%
          Preferred Stock has been converted on the 5% Preferred Stock
          Redemption Date (as hereinafter defined) multiplied by (B) the average
          Closing Bid Price (as hereinafter defined) of shares of Common Stock
          for the five (5) trading days immediately preceding the 5% Preferred
          Stock Redemption Date. Notwithstanding the foregoing, a redemption
          shall not occur pursuant to this Subsection G(1) with respect to any
          5% Preferred Stock for which a holder has previously submitted a
          Notice of Conversion pursuant to Subsection H of this Section 6. For
          purposes of this Section 6, the term "Closing Bid Price" means, for
          any security as of any date, the closing bid price on the principal
          securities exchange or trading market where the Common Stock is listed
          or traded as reported by Bloomberg, L.P. ("Bloomberg") or, if
          applicable, the closing bid price of the Common Stock in the over-the-
          counter market on the electronic bulletin board for such security as
          reported by Bloomberg, or, if no closing bid price is reported for the
          Common Stock by Bloomberg, then the average of the bid

                                       18

 
          prices of any market makers for such security as reported in the "pink
          sheets" by the National Quotation Bureau, Inc. If the Closing Bid
          Price of the Common Stock can not be calculated on such date on any of
          the foregoing bases, the Closing Bid Price of the Common Stock on such
          date shall be the fair market value as mutually determined by the
          Corporation and the holders of a majority of the outstanding shares of
          Series A Preferred Stock being converted for which the calculation of
          the Closing Bid Price is required in order to determine the Conversion
          Price of such shares. "Trading day" shall mean any day on which the
          Corporation's Common Stock is traded for any period on the principal
          securities exchange or other securities market on which the Common
          Stock is then being traded.

               (2)  Upon receipt of a notice given pursuant to Subsection G(1),
          each holder of Series A Preferred Stock shall have thirty days to
          decide whether to accept its ratable portion (based on its holdings of
          Series A Preferred Stock as compared to the aggregate number of shares
          of Series A Preferred Stock then outstanding) of such offer by
          tendering such holder's shares to the Corporation for redemption, at
          an address to be set forth in such notice, at any time prior to 5:00
          p.m. New York time on the 30th day following the mailing of such
          notice (the "Series A Preferred Stock Redemption Date") or to convert
          all or a portion of the Series A Preferred Stock. Notwithstanding the
          foregoing, nothing herein shall limit the rights of the holders of the
          Series A Preferred Stock to convert the Series A Preferred Stock in
          whole or in part, prior to the Series A Preferred Stock Redemption
          Date. Within three (3) business days after the Series A Preferred
          Stock Redemption Date, the Corporation shall remit the applicable
          redemption price, calculated pursuant to Subsection G(1) of this
          Section 7, by wire transfer to each holder of the Series A Preferred
          Stock to the most recent address of each holder as set forth on the
          records of the Corporation or its transfer agent.

               (3)  Any shares of Series A Preferred Stock redeemed pursuant to
          this Subsection G or otherwise acquired by the Corporation in any
          manner whatsoever shall be canceled and shall not under any
          circumstances be reissued. The Corporation may from time to time take
          such appropriate corporate action as may be necessary to reduce
          accordingly the number of authorized shares of the Corporation's
          capital stock.

          H.   Conversion.

               (1)  Subject to Subsection G(2) of this Section 7, the holders of
          the Series A Preferred Stock shall have conversion rights as follows
          (the "Series A Preferred Stock Conversion Rights"):

                    (a)  Each share of Series A Preferred Stock shall be
               convertible, at the option of the holder thereof, at any time and
               from time to time, into such number of fully paid and
               nonassessable shares of Common Stock as is determined by dividing
               $1,000, plus the amount of any accrued and unpaid dividends the
               Corporation elects to pay in Common Stock, by the Conversion
               Price in effect at the time of conversion. The Conversion Price
               at which shares of Common Stock shall be deliverable upon
               conversion of Series A Preferred Stock without the payment of
               additional consideration by the holder thereof (the "Conversion
               Price") shall be the lower of (i) 105% of the average Closing Bid
               Price of the shares of Common Stock for the five (5) trading days
               between November 2 through November 6 ($5.71) or (ii) 80% of the
               average Closing Bid Price of the shares of Common Stock for any
               five (5) consecutive trading days during the twenty (20)
               consecutive trading days immediately preceding the Series A
               Preferred Stock Conversion Date (as hereinafter defined).

                    (b)  At any time that the number of shares of Common Stock
               issued (A) upon conversion of the Series A Preferred Stock and
               (B) in lieu of

                                       19

 
          dividend payments on the Series A Preferred Stock, shall equal 630,000
          (a "Common Stock Redemption Event"), the Corporation shall (x) redeem,
          at a price determined in accordance with Subsection G(1) of this
          Section 7, all of the outstanding Series A Preferred Stock in
          accordance with the provisions of Subsection G(2) or (y) call a
          special meeting of its shareholders for the purpose of approving the
          transactions contemplated by the Securities Purchase Agreement,
          including the issuance of the Series A Preferred Stock on the terms
          set forth therein, together with any other approvals that shall be
          required so as to cause the transactions contemplated by the
          Securities Purchase Agreement to remain in compliance with the Rules
          and Regulations of The Nasdaq Stock Market (including Rule 4320 of
          Nasdaq's Non-Qualitative Designation Criteria in connection with
          conversions of Series A Preferred Stock; such approvals are referred
          to herein as the "Required Approvals"). The Corporation shall
          determine within five (5) business days following the receipt of a
          Notice of Conversion which of such actions it shall take, and shall
          promptly furnish notice to each of the holders of Series A Preferred
          Stock as to such determination, including, if applicable, a notice of
          redemption. In no event shall the Corporation issue shares of Common
          Stock upon conversion of, or in lieu of interest payments on, the
          Series A Preferred Stock, after the occurrence of a Common Stock
          Redemption Event until the Required Approvals, if any, are obtained.

               (c)  If the Corporation elects to call a special meeting of its
          shareholders pursuant to Subsection H(1)(b) of this Section 7 to
          obtain the Required Approvals, the Corporation shall use its best
          efforts to obtain such Required Approvals within thirty (30) days of
          the Common Stock Redemption Event (such thirty (30) day period is
          referred to herein as an "Approval Period"). If the Corporation does
          not obtain the Required Approvals within the Approval Period and the
          Corporation receives a Notice of Conversion after the termination of
          the Approval Period, the Corporation must redeem, in accordance with
          this Subsection H of this Section 7, any shares of Series A Preferred
          Stock outstanding after the Corporation has issued in excess of
          630,000 shares of Common Stock in connection with conversions of the
          Series A Preferred Stock.

               (d)  If the Corporation elects, pursuant to this Subsection H, to
          redeem the Series A Preferred Stock on the occurrence of a Common
          Stock Redemption Event, it shall redeem such Series A Preferred Stock
          at the price determined in accordance with Subsection G(1) of this
          Section 7. If the Corporation shall have elected, pursuant to this
          Subsection H(1), to obtain the Required Approvals but shall not have
          done so by the later of the occurrence of the Common Stock Redemption
          Event or the expiration of the Approval Period, it shall furnish a
          redemption notice to the Purchasers within three (3) business days
          after the expiration of the Approval Period.

          (2)  The Series A Preferred Stock Conversion Rights shall be exercised
     as follows:

               (a)  The Corporation will permit each holder of Series A
          Preferred Stock to exercise its right to convert the Series A
          Preferred Stock by faxing an executed and completed notice of
          conversion (the "Notice of Conversion") to the Corporation, and
          delivering within three (3) business days thereafter, the original
          Notice of Conversion (and the certificates representing the related
          shares of Series A Preferred Stock) to the Corporation by hand
          delivery or by express courier, duly endorsed. Each date on which a
          Notice of Conversion is faxed to and received in accordance with the
          provisions hereof shall be deemed a "5%

                                       20

 
          Preferred Stock Conversion Date." The Corporation will transmit the
          certificates representing the Common Stock issuable upon conversion of
          the Series A Preferred Stock (together with certificates representing
          the related shares of Series A Preferred Stock not so converted and,
          if applicable, a check representing any fraction of a share not
          converted) to such holder via express courier as soon as practicable,
          but in all events no later than the later to occur of (the "Delivery
          Date") (i) three (3) business days after the Series A Preferred Stock
          Conversion Date, or (ii) three (3) business days after receipt by the
          Corporation of the original Notice of Conversion (and the certificates
          representing the related shares of Series A Preferred Stock). For
          purposes of this Section 7, such conversion of the Series A Preferred
          Stock shall be deemed to have been made immediately prior to the close
          of business on the Series A Preferred Stock Conversion Date.

               (b)  In lieu of delivering physical certificates representing the
          Common Stock issuable upon the conversion of the Series A Preferred
          Stock, provided that the Corporation's transfer agent is participating
          in the Depository Trust Corporation ("DTC") Fast Automated Securities
          Transfer program, on the written request of a holder of Series A
          Preferred Stock who shall have previously instructed such holder's
          prime broker to confirm such request to the Corporation's transfer
          agent, the Corporation shall use commercially reasonable efforts to
          cause its transfer agent to electronically transmit such Common Stock
          to such holder by crediting the account of the holder's prime broker
          with DTC through its Deposit Withdrawal Agent Commission system no
          later than the applicable Delivery Date.

               (c)  The Corporation will at all times have authorized and
          reserved for the purpose of issuance a sufficient number of shares of
          Common Stock to provide for the conversion of the Series A Preferred
          Stock. The Corporation will use its best efforts at all times to
          maintain a number of shares of Common Stock so reserved for issuance
          that is no less than one and one-half (1.5) times the number that is
          then actually issuable upon the conversion of the Series A Preferred
          Stock and the exercise of the Warrants issued pursuant to that certain
          Securities Purchase Agreement (the "Securities Purchase Agreement")
          dates as of November 9, 1998, between the Corporation and the
          purchasers named therein. Before taking any action which would cause
          an adjustment reducing the Conversion Price below the established par
          value of the shares of Common Stock issuable upon conversion of the
          Series A Preferred Stock, the Corporation will take any corporate
          action which may, in the opinion of its counsel, be necessary in order
          that the Corporation may validly and legally issue fully paid and
          nonassessable shares of Common Stock at such adjusted Conversion
          Price.

               (d)  All shares of Series A Preferred Stock, which shall have
          been surrendered for conversion as herein provided shall no longer be
          deemed to be outstanding, and all rights with respect to such shares,
          including the rights, if any, to receive dividends, notices and to
          vote, shall immediately cease and terminate on the Series A Preferred
          Stock Conversion Date, except only the right of the holders thereof to
          receive shares of Common Stock in exchange therefor. Any shares of
          Series A Preferred Stock so converted shall be retired and canceled
          and shall not be reissued, and the Corporation may from time to time
          take such appropriate action as may be necessary to reduce the number
          of shares of authorized Series A Preferred Stock accordingly.

                                       21

 
          (3)  In the event of a liquidation of the Corporation, the Series A
     Preferred Stock Conversion Rights shall terminate at the close of business
     on the first full day preceding the date fixed for the payment of any
     amounts distributable on liquidation to the holders of the Series A
     Preferred Stock.

          (4)  If the conversion is in connection with an underwritten offer of
     securities registered pursuant to the Securities Act of 1933, as amended,
     the conversion may, at the option of any holder tendering Series A
     Preferred Stock for conversion, be conditioned upon the closing with the
     underwriter of the sale of securities pursuant to such offering, in which
     event the person(s) entitled to receive the Common Stock issuable upon such
     conversion of the Series A Preferred Stock shall not be deemed to have
     converted such Series A Preferred Stock until immediately prior to the
     closing of the sale of securities.

          (5)  At no time shall any holder (including any of its affiliates) of
     the Series A Preferred Stock convert such amount of Series A Preferred
     Stock as shall result in such Purchaser's (together with its affiliate's)
     ownership, after such conversion, exceeding 9.9% of the Corporation's
     outstanding Common Stock.

          (6)  No fractional shares of Common Stock shall be issued upon
     conversion of the Preferred Stock. In lieu of fractional shares, the
     Corporation shall pay cash equal to such fraction multiplied by the then
     effective and applicable Conversion Price.

          (7)  The Corporation will not, by amendment of its Articles of
     Incorporation or through any reorganization, transfer of assets,
     consolidation, merger, dissolution, issue or sale of securities or any
     other voluntary action, avoid or seek to avoid the observance or
     performance of any of the terms to be observed or performed under this
     Subsection H by the Corporation, but will at all times in good faith assist
     in the carrying out of all the provisions of this Subsection H and in the
     taking of all such action as may be necessary or appropriate in order to
     protect the Series A Preferred Stock Conversion Rights of the holders of
     the Series A Preferred Stock against impairment.

          (8)  In the event (a) that the Corporation declares a dividend (or any
     other distribution) on its Common Stock payable in Common Stock or other
     securities of the Corporation, (b) that the Corporation subdivides or
     combines its outstanding shares of Common Stock, (c) of any
     reclassification of the Common Stock of the Corporation (other than a
     subdivision or combination of its outstanding shares of Common Stock or a
     stock dividend or stock distribution thereon), (d) of any consolidation or
     merger of the Corporation into or with another corporation, (e) of the sale
     of all or substantially all of the assets of the Corporation, or (f) of the
     involuntary or voluntary dissolution, liquidation or winding up of the
     Corporation, then the Corporation shall cause to be filed at its principal
     office or at the office of the transfer agent of the Preferred Stock, and
     shall cause to be mailed to each holder of the Preferred Stock at their
     last address as shown on the records of the Corporation or such transfer
     agent, at least ten (10) days prior to the record date specified in (i)
     below or twenty (20) days before the date specified in (ii) below, a notice
     stating

               (i)  the record date of such dividend, distribution, subdivision
          or combination, or, if a record is not to be taken, the date as of
          which the holders of Common Stock of record to be entitled to such
          dividend, distribution, subdivision or combination are to be
          determined, or

               (ii) the date on which such reclassification, consolidation,
          merger, sale, dissolution, liquidation or winding up is expected to
          become effective, and the date as of which it is expected that holders
          of Common Stock of record shall

                                       22

 
               be entitled to exchange their shares of Common Stock for
               securities or other property deliverable upon such
               reclassification, consolidation, merger, sale, dissolution or
               winding up.

          I.   Sinking Fund.  There shall be no sinking fund for the payment of
     dividends, or liquidation preferences on the Series A Preferred Stock or
     the redemption of any shares thereof.

          J.   Amendment.  This Section 7 constitutes an agreement between the
     Corporation and the holders of the Series A Preferred Stock. The
     Corporation shall not amend this Section 7 or alter or repeal the
     preferences, rights, powers or other terms of the Series A Preferred Stock
     so as to affect adversely the Series A Preferred Stock, without the written
     consent or affirmative vote of the holders of at least sixty-six and two-
     thirds percent (662/3%) of the then outstanding shares of Series A
     Preferred Stock, given in writing or by vote at a meeting, consenting or
     voting (as the case may be) separately as a class.

                                   EXHIBIT A

     7.   Designation of Preferred Stock.  The Corporation shall establish and
reserve for issuance from its 5,000,000 authorized shares of Preferred Stock a
class of convertible preferred stock consisting of 1,400 shares to be designated
as the Series A Preferred Stock (the "Series A Preferred Stock"). The Series A
Preferred Stock shall have a stated value of the Liquidation Preference (as
hereinafter defined). Except as otherwise expressly stated in this Section 7,
all shares of the Series A Preferred Stock shall be identical to the shares of
5% Preferred Stock and 10% Preferred Stock, and the holders of Series A
Preferred Stock shall be entitled to the same preferences, limitations and
relative rights as the holders of 5% Preferred Stock and 10% Preferred Stock.

          A.   Dividends.

               (1)  Holders of the Series A Preferred Stock shall be entitled to
          receive, out of funds legally available therefor, dividends at a rate
          equal to 5% (the "Dividend Rate") of the Liquidation Preference per
          share per annum (subject to appropriate adjustments in the event of
          any stock dividend, stock split, combination or other similar
          recapitalization affecting such shares), and no more, payable in
          accordance with the provisions of this Section 7.

               (2)  At the election of the Corporation, each dividend on Series
          A Preferred Stock shall be paid either in shares of Common Stock or in
          cash on the Delivery Date (as defined in Subsection H(2)(a) of this
          Section 7) with respect to any shares of Series A Preferred Stock
          which are the subject of a Notice of Conversion (as defined in
          Subsection H(2) of this Section 7). Dividends paid in shares of Common
          Stock shall be paid (based on an assumed value of $1,000 per share) in
          full shares only, with a cash payment equal to the value of any
          fractional shares. Each dividend paid in cash shall be mailed to the
          holders of record of the Series A Preferred Stock as their names and
          addresses appear on the share register of the Corporation or at the
          office of the transfer agent on the corresponding dividend payment
          date. Holders of Series A Preferred Stock will receive written
          notification from the Corporation or the transfer agent if a dividend
          is paid in kind, which notification will specify the number of shares
          of Common Stock paid as a dividend and the recipient's aggregate
          holdings of Common Stock as of that dividend payment date and after
          giving effect to the dividend. All holders of shares of Common Stock
          issued as dividends shall be entitled to all of the rights and
          benefits relating to shares of Common Stock as set forth in the
          Corporation's Articles of Incorporation, as amended, and By-laws.

               (3)  Holders of the Series A Preferred Stock shall be entitled to
          payment of any dividends in preference and priority to any payment of
          any cash dividend on Common Stock or any other class or series of
          capital stock of the Corporation other than any other class or series
          of stock ranking senior ("Senior Preferred Stock") to the Series A
          Preferred Stock in respect of dividends, when and as declared by the
          Board of Directors of the Corporation.  The rights of the holders of
          Series A Preferred Stock, 5% Preferred Stock and 10% Preferred Stock
          to receive any dividends shall be equal in preference and priority.
          Dividends on the Series A Preferred Stock shall accrue with respect to
          each share of the Series A Preferred Stock from the date on which such
          share is issued and outstanding and thereafter shall be deemed to
          accrue from day to day whether or not earned or declared and whether
          or not there exists profits, surplus or other funds legally available
          for the payment of dividends, and shall be cumulative so that if such
          dividends on the Series A Preferred Stock shall not have been paid, or
          declared and set apart for payment, the deficiency shall be fully paid
          or declared and set apart for payment before any dividend shall be
          paid or declared or set apart for any Common Stock or other class or
          series of capital stock ranking junior to the Series A Preferred Stock
          (such stock 

                                       26

 
          being collectively referred to herein as the "Junior Stock") and
          before any purchase or acquisition of any Junior Stock is made by the
          Corporation, except the repurchase of Junior Stock from employees of
          the Corporation upon termination of employment. At the earlier of: (1)
          the redemption or conversion of the Series A Preferred Stock or (2)
          the liquidation of the Corporation, any accrued but undeclared
          dividends shall be paid to the holders of record of outstanding shares
          of the Series A Preferred Stock in accordance with the provisions of
          this Section 7. No accumulation of dividends on the Series A Preferred
          Stock shall bear interest.

          B.   Liquidation, Dissolution or Winding Up.

               (1)  In the event of any voluntary or involuntary liquidation,
          dissolution or winding up of the Corporation, the holders of shares of
          the Series A Preferred Stock then outstanding shall be entitled to be
          paid out of the assets of the Corporation available for distribution
          to its stockholders, after and subject to the payment in full of all
          amounts required to be distributed to the holders of any Senior
          Preferred Stock ranking on liquidation prior and in preference to the
          Preferred Stock, but before any payment shall be made to the holders
          of Junior Stock by reason of their ownership thereof, an amount equal
          to $1,000 per share of Series A Preferred Stock (the "Liquidation
          Preference") plus any accrued but unpaid dividends (whether or not
          declared).  The rights of the holders of Series A Preferred Stock, 5%
          Preferred Stock and 10% Preferred Stock to receive any such
          distributions shall be equal in preference and priority.  If upon any
          such liquidation, dissolution or winding up of the Corporation the
          remaining assets of the Corporation available for distribution to its
          shareholders shall be insufficient to pay the holders of shares of the
          Series A Preferred Stock the full amount to which they shall be
          entitled, the holders of shares of the Series A Preferred Stock shall
          share ratably in any distribution of the remaining assets and funds of
          the Corporation in proportion to the respective amounts which would
          otherwise be payable in respect of the shares held by them upon such
          distribution if all amounts payable on or with respect to such shares
          were paid in full.

               (2)  After the payment of all preferential amounts required to be
          paid to the holders of the Series A Preferred Stock, 5% Preferred
          Stock and the 10% Preferred Stock upon the dissolution, liquidation,
          or winding up of the Corporation, all of the remaining assets and
          funds of the Corporation available for distribution to its
          shareholders shall be distributed ratably among the holders of the
          Series A Preferred Stock, 5% Preferred Stock and the Junior Stock,
          with each share of Series A Preferred Stock being deemed, for such
          purpose, to be equal to the number of shares of Common Stock,
          including fractions of a share, into which such share of Series A
          Preferred Stock and 5% Preferred Stock are convertible immediately
          prior to the close of business on the business day fixed for such
          distribution.

          C.   Voting.

               (1)  Each holder of outstanding shares of Series A Preferred
          Stock shall be entitled, at each meeting of shareholders of the
          Corporation (and with respect to written consents of shareholders in
          lieu of meetings) with respect to any and all matters presented to the
          shareholders of the Corporation for their action or consideration, to
          the number of votes equal to the number of whole shares of Common
          Stock into which the shares of Series A Preferred Stock held by such
          holder are convertible (as adjusted from time to time pursuant to
          Subsection H hereof) immediately after the close of business on the
          record date fixed for such meeting or the effective date of such
          written consent. Except as provided by law, by the provisions of
          Section J below, or by the provisions establishing any other series of
          preferred stock, holders of Series A Preferred Stock shall vote
          together with the holders Common Stock as a single class.

                                       27

 
               (2)  The holders of the Series A Preferred Stock shall not be
          entitled to any rights of cumulative voting with respect to their
          shares.

          D.   Preemptive Rights.  No holder of Preferred Stock shall have any
     preemptive or similar right to acquire any additional unissued or treasury
     shares of stock or securities of any class or rights, warrants or options
     to purchase stock or scrip or securities in any kind, including shares or
     securities convertible into shares or carrying stock purchase warrants or
     privileges.

          E.   Other Securities.  Subject to any limitations contained in these
     Articles of Incorporation, the Board of Directors of the Corporation
     reserves the right to establish additional classes and/or series of capital
     stock of the Corporation and to designate the preferences, limitations and
     relative rights of any such classes and/or series; provided, however, that
     no such class and/or series may have preferences, limitations and relative
     rights which are superior to or senior to the preferences, limitations and
     relative rights granted to the holders of the Series A Preferred Stock.

          F.   Capital Reorganization.  If the Corporation shall at any time
     hereafter subdivide or combine its outstanding shares of Common Stock,
     declare a dividend payable in Common Stock, or in case of any capital
     reorganization or reclassification of the shares of Common Stock of the
     Corporation, the number of shares of the Series A Preferred Stock and the
     stated value of the Series A Preferred Stock shall be adjusted
     appropriately to allow the holders of the Series A Preferred Stock, as
     nearly as reasonably possible, to maintain (i) the aggregate stated value
     of the Series A Preferred Stock and (ii) their pro rata interest in the
     Corporation and in the Common Stock upon conversion of the Series A
     Preferred Stock, that each holder had prior to any such subdivision,
     combination, stock dividend, reorganization or reclassification.

          G.   Optional Redemption

               (1)  At any time within the 90 days following November 9, 1998,
          the Corporation may, at its option, redeem all or any portion of the
          shares of Series A Preferred Stock then outstanding upon not less than
          thirty (30) days' written notice at a redemption price per share equal
          to the Liquidation Preference of the Series A Preferred Stock plus any
          accrued but unpaid dividends (whether or not declared); provided, that
          if at the time of the notice of any such redemption, the Registration
          Statement to be filed by the Corporation pursuant to Section 2(a) of
          that certain Registration Rights Agreement dated November 9, 1998,
          between the Corporation and Archer Investors LLC has not been declared
          effective by the Securities and Exchange Commission and remains
          effective until the Series A Preferred Stock Redemption Date, the
          redemption price per share shall be equal to 115% of the Liquidation
          Preference of the Series A Preferred Stock plus any accrued but unpaid
          dividends (whether or not declared). Notwithstanding the foregoing, a
          redemption shall not occur pursuant to this Subsection G(1) with
          respect to any Series A Preferred Stock for which a holder has
          previously submitted a Notice of Conversion pursuant to Subsection H
          of this Section 7. For purposes of these Articles of Amendment, the
          term "Closing Bid Price" means, for any security as of any date, the
          closing bid price on the principal securities exchange or trading
          market where the Common Stock is listed or traded as reported by
          Bloomberg, L.P. ("Bloomberg") or, if applicable, the closing bid price
          of the Common Stock in the over-the-counter market on the electronic
          bulletin board for such security as reported by Bloomberg, or, if no
          closing bid price is reported for the Common Stock by Bloomberg, then
          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 Closing Bid Price of the Common Stock can not be
          calculated on such date on any of the foregoing bases, the Closing Bid
          Price of the Common Stock on such date shall be the fair market value
          as mutually determined by the Corporation and the holders of a
          majority of the outstanding shares of Series A Preferred 

                                       28

 
          Stock being converted for which the calculation of the Closing Bid
          Price is required in order to determine the Conversion Price of such
          shares. "Trading day" shall mean any day on which the Corporation's
          Common Stock is traded for any period on the principal securities
          exchange or other securities market on which the Common Stock is then
          being traded.

               (2)  Upon receipt of a notice given pursuant to Subsection G(1),
          each holder of Series A Preferred Stock shall have thirty days to
          decide whether to accept its ratable portion (based on its holdings of
          Series A Preferred Stock as compared to the aggregate number of shares
          of Series A Preferred Stock then outstanding) of such offer by
          tendering such holder's shares to the Corporation for redemption, at
          an address to be set forth in such notice, at any time prior to 5:00
          p.m. New York time on the 30th day following the mailing of such
          notice (the "Series A Preferred Stock Redemption Date") or to convert
          all or a portion of the Series A Preferred Stock. Notwithstanding the
          foregoing, nothing herein shall limit the rights of the holders of the
          Series A Preferred Stock to convert the Series A Preferred Stock in
          whole or in part, prior to the Series A Preferred Stock Redemption
          Date. Within three (3) business days after the Series A Preferred
          Stock Redemption Date, the Corporation shall remit the applicable
          redemption price, calculated pursuant to Subsection G(1) of this
          Section 7, by wire transfer to each holder of the Series A Preferred
          Stock to the most recent address of each holder as set forth on the
          records of the Corporation or its transfer agent.

               (3)  Any shares of Series A Preferred Stock redeemed pursuant to
          this Subsection G or otherwise acquired by the Corporation in any
          manner whatsoever shall be canceled and shall not under any
          circumstances be reissued. The Corporation may from time to time take
          such appropriate corporate action as may be necessary to reduce
          accordingly the number of authorized shares of the Corporation's
          capital stock.

          H.   Conversion.

               (1)  Subject to Subsection G(2) of this Section 7, the holders of
          the Series A Preferred Stock shall have conversion rights as follows
          (the "Series A Preferred Stock Conversion Rights"):

                    (a)  Each share of Series A Preferred Stock shall be
               convertible, at the option of the holder thereof, at any time and
               from time to time, into such number of fully paid and
               nonassessable shares of Common Stock as is determined by dividing
               $1,000, plus the amount of any accrued and unpaid dividends the
               Corporation elects to pay in Common Stock, by the Conversion
               Price in effect at the time of conversion. The Conversion Price
               at which shares of Common Stock shall be deliverable upon
               conversion of Series A Preferred Stock without the payment of
               additional consideration by the holder thereof (the "Conversion
               Price") shall be the lower of (i) 105% of the average Closing Bid
               Price of the shares of Common Stock for the five (5) trading days
               between November 2 through November 6 ($5.71) or (ii) 80% of the
               average Closing Bid Price of the shares of Common Stock for any
               five (5) consecutive trading days during the twenty (20)
               consecutive trading days immediately preceding the Series A
               Preferred Stock Conversion Date (as hereinafter defined).

                    (b)  At any time that the number of shares of Common Stock
               issued (A) upon conversion of the Series A Preferred Stock and
               (B) in lieu of dividend payments on the Series A Preferred Stock,
               shall equal 630,000 (a "Common Stock Redemption Event"), the
               Corporation shall (x) redeem, at a price determined in accordance
               with Subsection G(1) of this Section 7, all of the outstanding
               Series A Preferred Stock in accordance with the provisions of

                                       29

 
               Subsection G(2) or (y) call a special meeting of its shareholders
               for the purpose of approving the transactions contemplated by the
               Securities Purchase Agreement, including the issuance of the
               Series A Preferred Stock on the terms set forth therein, together
               with any other approvals that shall be required so as to cause
               the transactions contemplated by the Securities Purchase
               Agreement to remain in compliance with the Rules and Regulations
               of The Nasdaq Stock Market (including Rule 4320 of Nasdaq's Non-
               Qualitative Designation Criteria in connection with conversions
               of Series A Preferred Stock; such approvals are referred to
               herein as the "Required Approvals"). The Corporation shall
               determine within five (5) business days following the receipt of
               a Notice of Conversion which of such actions it shall take, and
               shall promptly furnish notice to each of the holders of Series A
               Preferred Stock as to such determination, including, if
               applicable, a notice of redemption. In no event shall the
               Corporation issue shares of Common Stock upon conversion of, or
               in lieu of interest payments on, the Series A Preferred Stock,
               after the occurrence of a Common Stock Redemption Event until the
               Required Approvals, if any, are obtained.

                    (c)  If the Corporation elects to call a special meeting of
               its shareholders pursuant to Subsection H(1)(b) of this Section 7
               to obtain the Required Approvals, the Corporation shall use its
               best efforts to obtain such Required Approvals within thirty (30)
               days of the Common Stock Redemption Event (such thirty (30) day
               period is referred to herein as an "Approval Period"). If the
               Corporation does not obtain the Required Approvals within the
               Approval Period and the Corporation receives a Notice of
               Conversion after the termination of the Approval Period, the
               Corporation must redeem, in accordance with this Subsection H of
               this Section 7, any shares of Series A Preferred Stock
               outstanding after the Corporation has issued in excess of 630,000
               shares of Common Stock in connection with conversions of the
               Series A Preferred Stock.

                    (d)  If the Corporation elects, pursuant to this Subsection
               H, to redeem the Series A Preferred Stock on the occurrence of a
               Common Stock Redemption Event, it shall redeem such Series A
               Preferred Stock at the price determined in accordance with
               Subsection G(1) of this Section 7. If the Corporation shall have
               elected, pursuant to this Subsection H(1), to obtain the Required
               Approvals but shall not have done so by the later of the
               occurrence of the Common Stock Redemption Event or the expiration
               of the Approval Period, it shall furnish a redemption notice to
               the Purchasers within three (3) business days after the
               expiration of the Approval Period.

               (2)  The Series A Preferred Stock Conversion Rights shall be
          exercised as follows:

                    (a)  The Corporation will permit each holder of Series A
               Preferred Stock to exercise its right to convert the Series A
               Preferred Stock by faxing an executed and completed notice of
               conversion (the "Notice of Conversion") to the Corporation, and
               delivering within three (3) business days thereafter, the
               original Notice of Conversion (and the certificates representing
               the related shares of Series A Preferred Stock) to the
               Corporation by hand delivery or by express courier, duly
               endorsed. Each date on which a Notice of Conversion is faxed to
               and received in accordance with the provisions hereof shall be
               deemed a "Series A Preferred Stock Conversion Date." The
               Corporation will transmit the certificates representing the
               Common Stock issuable upon conversion of the Series A Preferred
               Stock (together with certificates representing the related 

                                       30

 
               shares of Series A Preferred Stock not so converted and, if
               applicable, a check representing any fraction of a share not
               converted) to such holder via express courier as soon as
               practicable, but in all events no later than the later to occur
               of (the "Delivery Date") (i) three (3) business days after the
               Series A Preferred Stock Conversion Date, or (ii) three (3)
               business days after receipt by the Corporation of the original
               Notice of Conversion (and the certificates representing the
               related shares of Series A Preferred Stock). For purposes of this
               Section 7, such conversion of the Series A Preferred Stock shall
               be deemed to have been made immediately prior to the close of
               business on the Series A Preferred Stock Conversion Date. 

                    (b)  In lieu of delivering physical certificates
               representing the Common Stock issuable upon the conversion of the
               Series A Preferred Stock, provided that the Corporation's
               transfer agent is participating in the Depository Trust
               Corporation ("DTC") Fast Automated Securities Transfer program,
               on the written request of a holder of Series A Preferred Stock
               who shall have previously instructed such holder's prime broker
               to confirm such request to the Corporation's transfer agent, the
               Corporation shall use commercially reasonable efforts to cause
               its transfer agent to electronically transmit such Common Stock
               to such holder by crediting the account of the holder's prime
               broker with DTC through its Deposit Withdrawal Agent Commission
               system no later than the applicable Delivery Date.

                    (c)  The Corporation will at all times have authorized and
               reserved for the purpose of issuance a sufficient number of
               shares of Common Stock to provide for the conversion of the
               Series A Preferred Stock. The Corporation will use its best
               efforts at all times to maintain a number of shares of Common
               Stock so reserved for issuance that is no less than one and one-
               half (1.5) times the number that is then actually issuable upon
               the conversion of the Series A Preferred Stock and the exercise
               of the Warrants issued pursuant to that certain Securities
               Purchase Agreement (the "Securities Purchase Agreement") dates as
               of November 9, 1998, between the Corporation and the purchasers
               named therein. Before taking any action which would cause an
               adjustment reducing the Conversion Price below the established
               par value of the shares of Common Stock issuable upon conversion
               of the Series A Preferred Stock, the Corporation will take any
               corporate action which may, in the opinion of its counsel, be
               necessary in order that the Corporation may validly and legally
               issue fully paid and nonassessable shares of Common Stock at such
               adjusted Conversion Price.

                    (d)  All shares of Series A Preferred Stock, which shall
               have been surrendered for conversion as herein provided shall no
               longer be deemed to be outstanding, and all rights with respect
               to such shares, including the rights, if any, to receive
               dividends, notices and to vote, shall immediately cease and
               terminate on the Series A Preferred Stock Conversion Date, except
               only the right of the holders thereof to receive shares of Common
               Stock in exchange therefor. Any shares of Series A Preferred
               Stock so converted shall be retired and canceled and shall not be
               reissued, and the Corporation may from time to time take such
               appropriate action as may be necessary to reduce the number of
               shares of authorized Series A Preferred Stock accordingly.

               (3)  In the event of a liquidation of the Corporation, the Series
          A Preferred Stock Conversion Rights shall terminate at the close of
          business on the first full day preceding the date fixed for the
          payment of any amounts distributable on liquidation to the holders of
          the Series A Preferred Stock.

                                       31

 
               (4)  If the conversion is in connection with an underwritten
          offer of securities registered pursuant to the Securities Act of 1933,
          as amended, the conversion may, at the option of any holder tendering
          Series A Preferred Stock for conversion, be conditioned upon the
          closing with the underwriter of the sale of securities pursuant to
          such offering, in which event the person(s) entitled to receive the
          Common Stock issuable upon such conversion of the Series A Preferred
          Stock shall not be deemed to have converted such Series A Preferred
          Stock until immediately prior to the closing of the sale of
          securities.

               (5)  At no time shall any holder (including any of its
          affiliates) of the Series A Preferred Stock convert such amount of
          Series A Preferred Stock as shall result in such Purchaser's (together
          with its affiliate's) ownership, after such conversion, exceeding 9.9%
          of the Corporation's outstanding Common Stock.

               (6)  No fractional shares of Common Stock shall be issued upon
          conversion of the Preferred Stock. In lieu of fractional shares, the
          Corporation shall pay cash equal to such fraction multiplied by the
          then effective and applicable Conversion Price.

               (7)  The Corporation will not, by amendment of its Articles of
          Incorporation or through any reorganization, transfer of assets,
          consolidation, merger, dissolution, issue or sale of securities or any
          other voluntary action, avoid or seek to avoid the observance or
          performance of any of the terms to be observed or performed under this
          Subsection H by the Corporation, but will at all times in good faith
          assist in the carrying out of all the provisions of this Subsection H
          and in the taking of all such action as may be necessary or
          appropriate in order to protect the Series A Preferred Stock
          Conversion Rights of the holders of the Series A Preferred Stock
          against impairment.

               (8)  In the event (a) that the Corporation declares a dividend
          (or any other distribution) on its Common Stock payable in Common
          Stock or other securities of the Corporation, (b) that the Corporation
          subdivides or combines its outstanding shares of Common Stock, (c) of
          any reclassification of the Common Stock of the Corporation (other
          than a subdivision or combination of its outstanding shares of Common
          Stock or a stock dividend or stock distribution thereon), (d) of any
          consolidation or merger of the Corporation into or with another
          corporation, (e) of the sale of all or substantially all of the assets
          of the Corporation, or (f) of the involuntary or voluntary
          dissolution, liquidation or winding up of the Corporation, then the
          Corporation shall cause to be filed at its principal office or at the
          office of the transfer agent of the Preferred Stock, and shall cause
          to be mailed to each holder of the Preferred Stock at their last
          address as shown on the records of the Corporation or such transfer
          agent, at least ten (10) days prior to the record date specified in
          (i) below or twenty (20) days before the date specified in (ii) below,
          a notice stating

                    (i)   the record date of such dividend, distribution,
               subdivision or combination, or, if a record is not to be taken,
               the date as of which the holders of Common Stock of record to be
               entitled to such dividend, distribution, subdivision or
               combination are to be determined, or

                    (ii)  the date on which such reclassification,
               consolidation, merger, sale, dissolution, liquidation or winding
               up is expected to become effective, and the date as of which it
               is expected that holders of Common Stock of record shall be
               entitled to exchange their shares of Common Stock for securities
               or other property deliverable upon such reclassification,
               consolidation, merger, sale, dissolution or winding up.

                                       32

 
          I.   Sinking Fund.  There shall be no sinking fund for the payment of
     dividends, or liquidation preferences on the Series A Preferred Stock or
     the redemption of any shares thereof.

          J.   Amendment.  This Section 7 constitutes an agreement between the
     Corporation and the holders of the Series A Preferred Stock. The
     Corporation shall not amend this Section 7 or alter or repeal the
     preferences, rights, powers or other terms of the Series A Preferred Stock
     so as to affect adversely the Series A Preferred Stock, without the written
     consent or affirmative vote of the holders of at least sixty-six and two-
     thirds percent (662/3%) of the then outstanding shares of Series A
     Preferred Stock, given in writing or by vote at a meeting, consenting or
     voting (as the case may be) separately as a class.

     The undersigned, Thomas S. Plunkett, Chief Financial Officer of Online

                                        Thomas S. Plunkett
                                        Chief Financial Officer

                                       34

 
                                   EXHIBIT A

     8.   DESIGNATION OF PREFERRED STOCK.  The Corporation shall establish and
reserve for issuance from its 5,000,000 authorized shares of Preferred Stock a
class of convertible preferred stock consisting of 5,000 shares to be designated
as the Series C Preferred Stock (the "Series C Preferred Stock"). The Series C
Preferred Stock shall have a stated value of the Liquidation Preference (as
hereinafter defined). Except as otherwise expressly stated in this Section 8,
all shares of the Series C Preferred Stock shall be identical to the shares of
10% Preferred Stock and Series A Preferred Stock, and the holders of Series C
Preferred Stock shall be entitled to the same preferences, limitations and
relative rights as the holders of 10% Preferred Stock and Series A Preferred
Stock.

          A.   Dividends.
               --------- 

               (1)  Dividend Rate.  Holders of the Series C Preferred Stock 
                    -------------     
          shall be entitled to receive, out of funds legally available therefor,
          dividends at a rate equal to 4% (the "Dividend Rate") of the
          Liquidation Preference per share per annum (subject to appropriate
          adjustments in the event of any stock dividend, stock split,
          combination or other similar recapitalization affecting such shares),
          and no more, payable in accordance with the provisions of this Section
          8.

               (2)  Payment of Dividend.  At the election of the Corporation, 
                    -------------------      
          each dividend on Series C Preferred Stock shall be paid either in
          shares of Common Stock or in cash on the Delivery Date (as defined in
          Subsection H(2)(a) of this Section 8) with respect to any shares of
          Series C Preferred Stock which are the subject of a Notice of
          Conversion (as defined in Subsection H(2) of this Section 8).
          Dividends paid in shares of Common Stock shall be paid (based on an
          assumed value equal to the effective Conversion Price as defined
          below) in full shares only, with a cash payment equal to the value of
          any fractional shares. Each dividend paid in cash shall be mailed to
          the holders of record of the Series C Preferred Stock as their names
          and addresses appear on the share register of the Corporation or at
          the office of the transfer agent on the corresponding dividend payment
          date. Holders of Series C Preferred Stock will receive written
          notification from the Corporation or the transfer agent if a dividend
          is paid in kind, which notification will specify the number of shares
          of Common Stock paid as a dividend and the recipient's aggregate
          holdings of Common Stock as of that dividend payment date and after
          giving effect to the dividend. All holders of shares of Common Stock
          issued as dividends shall be entitled to all of the rights and
          benefits relating to shares of Common Stock as set forth in the
          Corporation's Articles of Incorporation, as amended, and By-laws.

               (3)  Payment of Dividends on Other Capital Stock.  Holders of the
                    -------------------------------------------                 
          Series C Preferred Stock shall be entitled to payment of any dividends
          in preference and priority to any payment of any cash dividend on
          Common Stock or any other class or series of capital stock of the
          Corporation other than any other class or series of stock ranking
          senior ("Senior Preferred Stock") to the Series C Preferred Stock in
          respect of dividends, when and as declared by the Board of Directors
          of the Corporation.  The rights of the holders of Series C Preferred
          Stock, 10% Preferred Stock and Series A Preferred Stock to receive any
          dividends shall be equal in preference and priority.  Dividends on the
          Series C Preferred Stock shall accrue with respect to each share of
          the Series C Preferred Stock from the date on which such share is
          issued and outstanding and thereafter shall be deemed to accrue from
          day to day whether or not earned or declared and whether or not there
          exists profits, surplus or other funds legally available for the
          payment of dividends, and shall be cumulative so that if such
          dividends on the Series C Preferred Stock shall not have been paid, or
          declared and set apart for payment, the deficiency shall be fully paid
          or declared and set apart for payment before any dividend shall be
          paid or declared or set apart for any Common Stock or other class or
          series of capital stock ranking junior to the Series C Preferred Stock
          (such stock being collectively referred to herein as the "Junior
          Stock") and before any purchase or acquisition of any Junior Stock is
          made by 

                                       35

 
          the Corporation, except the repurchase of Junior Stock from employees
          of the Corporation upon termination of employment. At the earlier of:
          (1) the redemption or conversion of the Series C Preferred Stock or
          (2) the liquidation of the Corporation, any accrued but unpaid
          dividends (whether or not declared) shall be paid to the holders of
          record of outstanding shares of the Series C Preferred Stock in
          accordance with the provisions of this Section 8. No accumulation of
          dividends on the Series C Preferred Stock shall bear interest.

          B.   Liquidation, Dissolution or Winding Up.
               -------------------------------------- 

               (1)  Priority on Payment.  In the event of any voluntary or 
                    ------------------- 
          involuntary liquidation, dissolution or winding up of the Corporation,
          the holders of shares of the Series C Preferred Stock then outstanding
          shall be entitled to be paid out of the assets of the Corporation
          available for distribution to its stockholders, after and subject to
          the payment in full of all amounts required to be distributed to the
          holders of any Senior Preferred Stock ranking on liquidation prior and
          in preference to the Series C Preferred Stock, but before any payment
          shall be made to the holders of Junior Stock by reason of their
          ownership thereof, an amount equal to $1,000 per share of Series C
          Preferred Stock (the "Liquidation Preference") plus any accrued but
          unpaid dividends (whether or not declared). The rights of the holders
          of Series C Preferred Stock, 10% Preferred Stock and Series A
          Preferred Stock to receive any such distributions shall be equal in
          preference and priority. If upon any such liquidation, dissolution or
          winding up of the Corporation the remaining assets of the Corporation
          available for distribution to its shareholders shall be insufficient
          to pay the holders of shares of the Series C Preferred Stock the full
          amount to which they shall be entitled, the holders of shares of the
          Series C Preferred Stock shall share ratably in any distribution of
          the remaining assets and funds of the Corporation in proportion to the
          respective amounts which would otherwise be payable in respect of the
          shares held by them upon such distribution if all amounts payable on
          or with respect to such shares were paid in full.

                    -----------------------------------  
          all preferential amounts required to be paid to the holders of the
          Series C Preferred Stock, the 10% Preferred Stock and Series A
          Preferred Stock upon the dissolution, liquidation, or winding up of
          the Corporation, all of the remaining assets and funds of the
          Corporation available for distribution to its shareholders shall be
          distributed ratably among the holders of the Series A Preferred Stock,
          Series C Preferred Stock and the Junior Stock, with each share of
          Series C Preferred Stock being deemed, for such purpose, to be equal
          to the number of shares of Common Stock, including fractions of a
          share, into which such share of Series C Preferred Stock are
          convertible immediately prior to the close of business on the business
          day fixed for such distribution.

          from time to time pursuant to Subsection H hereof) immediately after
          the close of business on the record date fixed for such meeting or the
          effective date of such written consent. Except as provided by law, by
          the provisions of Section J below, or by the provisions establishing
          any other series of preferred stock, holders of Series C Preferred

     reserves the right to establish additional classes and/or series of capital
     stock of the Corporation and to designate the preferences, limitations and
     relative rights of any such classes and/or series; provided, however, that
     no such class and/or series may have preferences, limitations and relative

     stated value of the Series C Preferred Stock shall be adjusted
     appropriately to allow the holders of the Series C Preferred Stock, as
     nearly as reasonably possible, to maintain (i) the aggregate stated value
     of the Series C Preferred Stock and (ii) their pro rata interest in the
     Corporation and in the Common Stock upon conversion of the Series C
     Preferred Stock, that each holder had prior to any such subdivision,
     combination, stock dividend, reorganization or reclassification.

                    (b)  Redemption After Effectiveness Deadline.  On any date
                         ---------------------------------------

          Agreement) the Corporation may elect to redeem Series C Preferred

          (appropriately adjusted for any stock split, stock dividend,

          Corporation shall redeem a number of shares of Series C Preferred
          Stock from each holder of Series C Preferred Stock submitted for
          conversion on the applicable date equal to such holder's pro-rata
          amount (based on the number of shares of Series C Preferred Stock held
          by such holder relative to the number of Series C Preferred Stock
          outstanding) of all shares of Series C Preferred Stock submitted for
          conversion which the Corporation elects to redeem.

               Lieu of Conversion" shall be an amount per share of Series C
               Preferred Stock equal to the product of (i) the number of shares
               of Common Stock otherwise issuable upon conversion of such shares
               of Series C Preferred Stock on the applicable Conversion Date,
               and (ii) the Closing Bid Price (as defined below) of the Common
               Stock on the Conversion Date.

                    (b)  Mechanics of Corporation Redemption in Lieu of 
                         ----------------------------------------------
               Conversion.  The Corporation shall exercise its right to redeem

               ("Notice of Corporation Redemption in Lieu of Conversion") to (i)
               each holder of the Series C Preferred Stock, and (ii) the
               Transfer Agent. Such Notice of Corporation Redemption in Lieu of
               conversion shall indicate (A) the maximum, if any, aggregate
               number of Series C Preferred Stock which the Corporation will

               confirm the time period during which the Corporation may effect
               Corporation Redemption in Lieu of Conversion, which period shall
               begin on and include the date which is five (5) trading days
               after the date of receipt by all of the holders' of the Notice of
               Redemption in Lieu of Conversion and shall end on and include the
               date which is thirty (30) calendar days after the fifth (5th)
               trading day following the date of receipt by all of the holders

               number of Series C Preferred Stock which it will redeem during

               shall allocate for redemption from each holder of Series C
               Preferred Stock a number of shares of Series C Preferred Stock
               equal to such holder's pro-rata amount (based on the number of
               shares of Series C Preferred Stock held by such holder on the
               date of the Notice of Corporation Redemption in Lieu of
               Conversion relative to the total number of shares of Series C
               Preferred Stock outstanding on such date). The Corporation may
               terminate a Redemption in Lieu of Conversion Period at any time
               with respect to Series C Preferred Stock which has not been
               submitted for conversion by delivering written notice of such
               termination to each holder of Series C Preferred Stock by
               facsimile and overnight courier at least five (5) business days
               prior to the effective date of such termination. Notwithstanding
               anything to the contrary in this Subsection 8G(2), the
               Corporation shall convert Series C Preferred Stock pursuant to
               Subsection 8H if (A) such Series C Preferred Stock are submitted
               for conversion (i) before the beginning, or after the effective
               date of the termination, of the Redemption in Lieu of Conversion
               Period, or (ii) at a Conversion Price greater than or equal to
               the Redemption in Lieu of Conversion Trigger Price or (B) such
               Series C Preferred Stock is in excess of such holder's pro-rata
               allocation of the maximum number of Series C Preferred Stock the
               Corporation indicated that it would redeem in its Notice of
               Corporation Redemption in Lieu of Conversion. If the Company
               fails to timely effect a Company Redemption in Lieu of Conversion
               in accordance with this Subsection 8G(2), the Company shall not
               be allowed to submit another Notice of Company Redemption in Lieu
               of Conversion without the prior written consent of the holders of
               at least two-thirds (2/3) of the Series C Preferred Stock then
               outstanding.

               (3)  Mechanics of Redemption.  Upon receipt of a notice given 
                    -----------------------        
          pursuant to this Subsection 8G, unless such redemption is pursuant to
          Subsection 8G(2), each holder of Series C Preferred Stock shall have
          thirty (30) days to decide whether to accept its ratable portion
          (based on its holdings of Series C Preferred Stock as compared to the
          aggregate number of shares of Series C Preferred Stock then
          outstanding) of such offer by tendering such holder's shares to the
          Corporation for redemption, at an address to be set forth in such

          following the mailing of such notice (the "Series C Preferred Stock
          Redemption Date") or to convert all or a portion of the Series C
          Preferred Stock. Within three (3) business days after the Series C
          Preferred Stock Redemption Date, the Corporation shall remit the
          applicable redemption price, calculated pursuant to Subsection G of
          this Section 8, by wire transfer to each holder of the Series C
          Preferred Stock to the most recent address of each holder as set forth
          on the records of the Corporation or its transfer agent, together with
          all applicable Warrants.

               (4)  Cancellation of Shares.  Any shares of Series C Preferred 
                    ----------------------    
          Stock redeemed pursuant to this Subsection G or otherwise acquired by
          the Corporation in any manner whatsoever shall be canceled and shall
          not under any circumstances be reissued. The Corporation may from time
          to time take such appropriate corporate action as may be necessary to
          reduce accordingly the number of authorized shares of the
          Corporation's capital stock.

               Corporation elects to pay in Common Stock, by the Conversion
               Price in effect at the time of conversion.  The Conversion Price
               at which shares of Common Stock shall be deliverable upon
               conversion of Series C Preferred Stock without the payment of
               additional consideration by the holder thereof (the "Conversion
               Price") shall be the lower of (i) 140% of the Closing Bid Price
               of the Common Stock at the Initial Closing Date or Mandatory
               Closing Date (as defined in the Securities Purchase Agreement)
               whichever is the original issuance date for the Series C

               Preferred Shares (as defined in the Securities Purchase
               Agreement) or the Mandatory Closing Date in the case of the
               conversion of Mandatory Preferred Shares (as defined in the
               Securities Purchase Agreement), 100% of the Closing Bid Price of
               the Common Stock on the trading day closest to the date 120 days
               after the Initial Closing Date  in the case of the conversion of

               case of the conversion of the Mandatory Preferred Shares,
               whichever is applicable (such price being the "Maximum Conversion
               Price"); or (ii) 100% (the "Conversion Percentage") of the Market
               Price (as defined below) on the date of the Notice of Conversion

               market where the Common Stock is listed or traded as reported by
               Bloomberg, L.P. ("Bloomberg") or, if applicable, the closing bid
               price of the Common Stock in the over-the-counter market on the
               electronic bulletin board for such security as reported by
               Bloomberg, or, if no closing bid price is reported for the Common
               Stock by Bloomberg, then 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 Closing Bid Price
               of the Common Stock can not be calculated on such date on any of
               the foregoing bases, the Closing Bid Price of the Common Stock on
               such date shall be the fair market value as mutually determined
               by the Corporation and the holders of a majority of the
               outstanding shares of Series C Preferred Stock being converted
               for which the calculation of the Closing Bid Price is required in
               order to determine the Conversion Price of such shares.  "Trading
               day" shall mean any day on which the Corporation's Common Stock
               is traded for any period on the principal securities exchange or
               other securities market on which the Common Stock is then being
               traded.

                    (b)  Mandatory Conversion.  If any Series C Preferred Stock 
                         --------------------          
               remain outstanding on the Maturity Date (as defined below), then
               all such Series C Preferred Stock shall be converted as of such
               date in accordance with this Subsection H as if the holders of
               such Series C Preferred Stock had given the Notice of Conversion
               on the Maturity Date. All holders of Series C Preferred Stock
               shall, on the Maturity Date, surrender all Series C Preferred
               Stock Certificates, duly endorsed for conversion, to the
               Corporation. Notwithstanding the foregoing, if on the Maturity
               Date the Common Stock is not designated for quotation on The
               Nasdaq SmallCap Market or the Nasdaq National Market or listed on
               The New York Stock Exchange, Inc. or The American Stock 

                                       40

 
               Exchange, Inc., then the Maturity Date shall be extended until
               the Common Stock is so designated or listed. "Maturity Date"
               means the date which is five (5) years after the Initial Closing
               Date, or the Mandatory Closing Date (as those terms are defined
               in the Securities Purchase Agreement), whichever is applicable,
               subject to extension as described in the immediately preceding
               sentence.

                    (d)  Conversion at the Corporation's Election.  On any day 
                         ----------------------------------------     
               within twenty (20) trading days immediately following any twenty
               (20) consecutive trading days during which the Closing Bid Price
               of the Common Stock on each trading day during such twenty (20)
               consecutive trading days is not less than 200% of the Maximum
               Conversion Price applicable to an outstanding share of Series C
               Preferred Stock in effect on the first day of such twenty (20)
               consecutive trading days, the Corporation shall have the right,
               in its sole discretion, to require that any or all of such
               outstanding Series C Preferred Stock be converted ("Conversion at
               Corporation's Election") at the Conversion Price; provided that
               the Conditions to Conversion at the Corporation's Election (as
               set forth below) and the other terms of this Subsection 8H(1)(d)
               are satisfied.  The Corporation shall exercise its right to
               Conversion at Corporation's Election by providing each holder of
               Series C Preferred Stock that is then subject to the Conversion
               at Corporation's Election written notice ("Notice of Conversion
               at Corporation's Election") at least ten (10) trading days prior
               to the date selected by the Corporation for such conversion
               ("Corporation's Election Conversion Date").  If the Corporation
               elects to require conversion of some, but not all, of such Series
               C Preferred Stock, the Corporation shall convert an amount from
               each holder of such Series C Preferred Stock equal to such
               holder's pro-rata amount (based on the number of such Series C
               Preferred Stock held by such holder relative to the total number
               of such Series C Preferred Stock outstanding on the date of the
               Corporation's delivery of the Notice of Conversion at
               Corporation's Election) of all such Series C Preferred Stock the
               Corporation is requiring to be converted.  The Notice of
               Conversion at Corporation's Election shall indicate (x) the
               number of shares of Series C Preferred Stock subject to this
               subsection that the Corporation has selected for conversion, (y)
               the Corporation's Election Conversion Date, which date shall be
               not less than ten (10) or more than thirty (30) trading days
               after each holder's receipt of such notice, and (z) each holder's
               pro-rata share of such outstanding Series C Preferred Stock the
               Corporation is requiring to be converted.  All Series C Preferred
               Stock selected for conversion in accordance with the provision of
               this Subsection 8H(1)(d) and which have not been converted prior
               to the Corporation's Election Conversion Date shall be converted
               as of the Corporation's Election Conversion Date in accordance
               with this Subsection 8(H) as if the holders of such Series C
               Preferred Stock selected by the Corporation to be converted had
               given a Notice of Conversion on the Corporation's Election
               Conversion Date.  "Conditions to Conversion at the Corporation's
               Election" means the following conditions:  (i) the Registration
               Statement(s) relating to the shares of Common Stock issuable upon
               such conversion shall be effective and available for the sale of
               all such shares (without regard to any limitations on conversion
               herein or elsewhere); (ii) on each day during the period
               beginning on and including the date which is twenty (20) trading
               days prior to the date of the Corporation's Notice of Conversion
               at Corporation's Election and ending on and including the
               Corporation's Election Conversion Date, the Common Stock is
               designated for quotation on The Nasdaq SmallCap Market or the
               Nasdaq National Market or listed on The New York Stock Exchange,
               Inc. or The American Stock Exchange, Inc. and is not suspended
               from trading; and (iii) on each day during the twenty (20)
               consecutive trading days immediately preceding the date of the
               receipt by the holders of Maximum Conversion Price of the Notice
               of Conversion at Corporation's Election, the Closing Bid Price of

                                       41

 
               the Common Stock is at least 200% of the Maximum Conversion Price
               in effect on the first day of such twenty (20) consecutive
               trading days.

                    (e)  Common Stock Redemption Event; Required Approvals.  At 
                         -------------------------------------------------  
               any time that the number of shares of Common Stock issued (A)
               upon conversion of the Series C Preferred Stock and (B) in lieu
               of dividend payments on the Series C Preferred Stock, shall equal
               930,000 shares of Common Stock less the number of shares, if any,
               subject to Warrants issued pursuant to Subsection 8G (a "Common
               Stock Redemption Event"), the Corporation shall (x) redeem, at a
               price determined in accordance with Subsection 8G(1)(b), all of
               the outstanding Series C Preferred Stock in accordance with the
               provisions of Subsection 8G(2) or (y) call a special meeting of
               its shareholders for the purpose of approving the transactions
               contemplated by the Securities Purchase Agreement, including the
               issuance of the Series C Preferred Stock on the terms set forth
               therein, together with any other approvals that shall be required
               so as to cause the transactions contemplated by the Securities
               Purchase Agreement to remain in compliance with the Rules and
               Regulations of The Nasdaq Stock Market (including Rule 4320 of
               Nasdaq's Non-Qualitative Designation Criteria in connection with
               conversions of Series C Preferred Stock; such approvals are
               referred to herein as the "Required Approvals"). The Corporation
               shall determine within five (5) business days following the
               receipt of a Notice of Conversion which of such actions it shall
               take, and shall promptly furnish notice to each of the holders of
               Series C Preferred Stock as to such determination, including, if
               applicable, a notice of redemption. In no event shall the
               Corporation issue shares of Common Stock upon conversion of, or
               in lieu of interest payments on, the Series C Preferred Stock,
               after the occurrence of a Common Stock Redemption Event until the
               Required Approvals, if any, are obtained.

                    (f)  Shareholders' Meeting.  If the Corporation elects to 
                         ---------------------      
               call a special meeting of its shareholders pursuant to Subsection
               8H(1)(e) to obtain the Required Approvals, the Corporation shall
               use its best efforts to obtain such Required Approvals within
               thirty (30) days of the Common Stock Redemption Event (such
               thirty (30) day period is referred to herein as an "Approval
               Period").  If the Corporation does not obtain the Required
               Approvals within the Approval Period and the Corporation receives
               a Notice of Conversion after the termination of the Approval
               Period, the Corporation must redeem, in accordance with this
               Subsection 8H, any shares of Series C Preferred Stock outstanding
               after the Corporation has issued in excess of 930,000 shares of
               Common Stock less the number of shares, if any, subject to
               Warrants issued pursuant to Subsection 8G in connection with
               redemptions of the Series C Preferred Stock.

                    (g)  Redemption Upon Common Stock Redemption Event.  If the
                         ---------------------------------------------         
               Corporation elects, pursuant to this Subsection 8H, to redeem the
               Series C Preferred Stock on the occurrence of a Common Stock
               Redemption Event, it shall redeem such Series C Preferred Stock
               at the price determined in accordance with Subsection 8G(1)(b).
               If the Corporation shall have elected, pursuant to this
               Subsection 8H(1), to obtain the Required Approvals but shall not
               have done so by the later of the occurrence of the Common Stock
               Redemption Event or the expiration of the Approval Period, it
               shall furnish a redemption notice to the holders of the Series C
               Preferred Stock within three (3) business days after the
               expiration of the Approval Period.

               (2)  Exercise of Conversion Rights.  The Series C Preferred Stock
                    -----------------------------                               
          Conversion Rights shall be exercised as follows:

                                       42

 
                    (a)  Notice of Conversion; Delivery of Certificates.  The 
                         ----------------------------------------------       
               Corporation will permit each holder of Series C Preferred Stock
               to exercise its right to convert the Series C Preferred Stock by
               faxing an executed and completed notice of conversion (the
               "Notice of Conversion") to the Corporation, and delivering within
               three (3) business days thereafter, the original Notice of
               Conversion (and the certificates representing the related shares
               of Series C Preferred Stock) to the Corporation by hand delivery
               or by express courier, duly endorsed. Each date on which a Notice
               of Conversion is faxed to and received in accordance with the
               provisions hereof shall be deemed a "Series C Preferred Stock
               Conversion Date." The Corporation will transmit the certificates
               representing the Common Stock issuable upon conversion of the
               Series C Preferred Stock (together with certificates representing
               the related shares of Series C Preferred Stock not so converted
               and, if applicable, a check representing any fraction of a share
               not converted) to such holder via express courier as soon as
               practicable, but in all events no later than the later to occur
               of (the "Delivery Date") (i) three (3) business days after the
               Series C Preferred Stock Conversion Date, or (ii) three (3)
               business days after receipt by the Corporation of the original
               Notice of Conversion (and the certificates representing the
               related shares of Series C Preferred Stock). For purposes of this
               Section 8, such conversion of the Series C Preferred Stock shall
               be deemed to have been made immediately prior to the close of
               business on the Series C Preferred Stock Conversion Date.

                    (b)  DTC Fast Automated Securities Transfer.  In lieu of 
                         --------------------------------------     
               delivering physical certificates representing the Common Stock
               issuable upon the conversion of the Series C Preferred Stock,
               provided that the Corporation's transfer agent is participating
               in the Depository Trust Corporation ("DTC") Fast Automated
               Securities Transfer program, on the written request of a holder
               of Series C Preferred Stock who shall have previously instructed
               such holder's prime broker to confirm such request to the
               Corporation's transfer agent, the Corporation shall use
               commercially reasonable efforts to cause its transfer agent to
               electronically transmit such Common Stock to such holder by
               crediting the account of the holder's prime broker with DTC
               through its Deposit Withdrawal Agent Commission system no later
               than the applicable Delivery Date.

                    (c)  Reservation of Shares.  The Corporation will at all 
                         ---------------------      
               times have authorized and reserved for the purpose of issuance a
               sufficient number of shares of Common Stock to provide for the
               conversion of the Series C Preferred Stock. The Corporation will
               use its best efforts at all times to maintain a number of shares
               of Common Stock so reserved for issuance that is no less than one
               and two (2) times the number that is then actually issuable upon
               the conversion of the Series C Preferred Stock and the exercise
               of any Warrants issued pursuant hereto. Before taking any action
               which would cause an adjustment reducing the Conversion Price
               below the established par value of the shares of Common Stock
               issuable upon conversion of the Series C Preferred Stock, the
               Corporation will take any corporate action which may, in the
               opinion of its counsel, be necessary in order that the
               Corporation may validly and legally issue fully paid and
               nonassessable shares of Common Stock at such adjusted Conversion
               Price.

                    (d)  Cancellation of Converted Shares.  All shares of Series
                         --------------------------------  
               C Preferred Stock, which shall have been surrendered for
               conversion as herein provided shall no longer be deemed to be
               outstanding, and all rights with respect to such shares,
               including the rights, if any, to receive dividends, notices and
               to vote, shall immediately cease and terminate on the Series C
               Preferred Stock Conversion Date, except only the right of the
               holders thereof to receive shares of Common Stock in exchange
               therefor. Any shares of Series C Preferred Stock 

                                       43

 
               so converted shall be retired and canceled and shall not be
               reissued, and the Corporation may from time to time take such
               appropriate action as may be necessary to reduce the number of
               shares of authorized Series C Preferred Stock accordingly.

               (3)  Cancellation of Conversion Rights on Liquidation.  In the 
                    ------------------------------------------------       
          event of a liquidation of the Corporation, the Series C Preferred
          Stock Conversion Rights shall terminate at the close of business on
          the first full day preceding the date fixed for the payment of any
          amounts distributable on liquidation to the holders of the Series C
          Preferred Stock.

               (4)  Conversion With an Underwritten Offering.  If the conversion
                    ----------------------------------------
          is in connection with an underwritten offer of securities registered
          pursuant to the Securities Act of 1933, as amended, the conversion
          may, at the option of any holder tendering Series C Preferred Stock
          for conversion, be conditioned upon the closing with the underwriter
          of the sale of securities pursuant to such offering, in which event
          the person(s) entitled to receive the Common Stock issuable upon such
          conversion of the Series C Preferred Stock shall not be deemed to have
          converted such Series C Preferred Stock until immediately prior to the
          closing of the sale of securities.

               (5)  Limitation on Conversion Right.  At no time shall any holder
                    ------------------------------                              
          (including any of its affiliates) of the Series C Preferred Stock
          convert such amount of Series C Preferred Stock as shall result in
          such holder's (together with its affiliate's) ownership, after such
          conversion, exceeding 9.9% of the Corporation's outstanding Common
          Stock.

               (6)  No Fractional Shares.  No fractional shares of Common Stock 
                    --------------------        
          shall be issued upon conversion of the Series C Preferred Stock. In
          lieu of fractional shares, the Corporation shall pay cash equal to
          such fraction multiplied by the then effective and applicable
          Conversion Price.

               (7)  Maintenance of Rights.  The Corporation will not, by 
                    ---------------------    
          amendment of its Articles of Incorporation or through any
          reorganization, transfer of assets, consolidation, merger,
          dissolution, issue or sale of securities or any other voluntary
          action, avoid or seek to avoid the observance or performance of any of
          the terms to be observed or performed under this Subsection 8H by the
          Corporation, but will at all times in good faith assist in the
          carrying out of all the provisions of this Subsection 8H and in the
          taking of all such action as may be necessary or appropriate in order
          to protect the Series C Preferred Stock Conversion Rights of the
          holders of the Series C Preferred Stock against impairment.

               (8)  Notice of Certain Events.  In the event (a) that the 
                    ------------------------
