      WHEREAS, Borrower is currently indebted to Lender pursuant to the terms
and conditions of that certain Amended and Restated Loan and Security
Agreement dated as of April 10, 2000 between Borrower and Lender (the "Loan
Agreement"); and

      WHEREAS, the Obligations mature on July 10, 2000; and

      WHEREAS, Borrower has not yet been able to refinance the Loan and its
present business plan is to continue to pursue refinancing of the Loan,

sale of all or a material part of Borrower's business as a going concern; and

      WHEREAS, Borrower has requested that Lender extend the Maturity Date of
the Obligations and Lender is willing to do so upon certain terms and
conditions as more particularly described herein;

      NOW, THEREFORE, in consideration of the premises, the mutual covenants
and agreements contained herein and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, Borrower,
Lender and Shareholder, intending to be legally bound, agree as follows:

Lender that, as of the date of execution of this Amendment, Borrower has no
offset, defense or counterclaim with respect thereto, no claim or defense in the
abatement or reduction thereof, or any other claim against Lender or with
respect to any document forming part of the transaction in respect of which the
Prior Loan Agreement was made or forming part of any other transaction under
which Borrower is indebted to Lender. Borrower acknowledges that all interest
imposed under the Prior Loan Agreement and Loan Documents through the date of
execution hereof, and all fees and other charges that have been collected from

      4. Release of Claims. In consideration of Lender's extension of the
Commitment and agreements contained herein, Borrower and its successors and
assigns each hereby fully release, remise and forever discharge Lender and Bank
and all of their past and present officers, directors, agents, employees,

respective heirs, personal representatives, predecessors, successors and
assigns, for, from and against any and all claims, demands, causes of action,

or contract and the duties arising thereunder that Borrower, or any of its
successors or assigns has had in the past, or now has, or which may hereafter
accrue, whether known or unknown, whether currently existing or hereafter
asserted, relating in any manner to, or arising from or in connection with, the
indebtedness evidenced by the Prior Loan Agreement, this Agreement or the Loan
Documents, any negotiations, loan administration, exercise of rights and
remedies, payment, offset with respect to, or other matter relating to such
indebtedness, any collateral securing payment and performance of such

any manner to such indebtedness, collateral or this Agreement; provided,
however, that the foregoing release and discharge shall not apply to the
obligations of Lender expressly set forth in this Amendment or first arising
after the date of this Amendment. Borrower acknowledges and agrees that Lender
is not and shall not be obligated in any way to continue or undertake any loan,
financing or other credit arrangement with Borrower, including without
limitation any renewal of the indebtedness evidenced by the Loan Agreement,
beyond the Maturity Date.

      5. Representations and Warranties of Borrower. To induce Lender to enter
into this Amendment and the arrangement contemplated by this Amendment, Borrower
represents and warrants to Lender as follows:

            (a) Borrower has all requisite corporate power and corporate
authority to execute this Amendment and to perform all of its obligations
hereunder, and this Amendment has been duly executed and delivered by Borrower
and constitutes the legal, valid and binding obligations of Borrower,
enforceable against Borrower in accordance with its terms.

            (b) The execution, delivery and performance by Borrower of this
Amendment have been duly authorized by all necessary corporate action and do not
(i) require any authorization, consent or approval by any governmental
department, commission, board, bureau, agency or instrumentality, domestic or
foreign, or any other Person, including, without limitation, the Subordinated
Creditors, that, if not obtained would have a material adverse effect on the
Borrower's financial condition, properties or operations; (ii) violate any
provision of any law, rule or regulation or of any order, writ, injunction or
decree presently in effect, having applicability to Borrower, or the articles of
incorporation or by-laws of Borrower; or (iii) result in a breach of or
constitute a default under any indenture or loan or credit agreement or any
other

material agreement, lease or instrument to which Borrower is a party or by which
it or its properties may be bound or affected.

            (c) Except as disclosed in the Borrower's May 31, 2000 financial
statements delivered to Lender or otherwise disclosed in writing to Lender, all
of the respective representations and warranties made by Borrower in the Loan
Agreement and Loan Documents remain true, complete and correct in all material
respects as of the date hereof, including, without limitation, the
representations and warranties in Article 5 of the Loan Agreement, except to the
extent of any changes to such representations and warranties previously
disclosed in writing to Lender.

            (d) After the execution of this Amendment, Borrower will be in
compliance in all material respects with all of the covenants of Borrower under
the Loan Agreement and other Loan Documents as of the date of execution of this
Amendment.

            (e) There are no oral agreements, understandings or course of
conduct that would modify, amend, rearrange, vary, diminish or impair the Loan
Agreement or other Loan Documents or the Obligation of Borrower evidenced
thereby or to perform fully the Obligations of Borrower in strict accordance
with the Loan Agreement and other Loan Documents, or which would permit Borrower
to void or avoid its obligations in whole or in part.

No representation or warranty made by Borrower and contained herein or in the
Loan Agreement or other Loan Documents, and no certificate, information or
report furnished or to be furnished by Borrower in connection with the Loan
Agreement or any of the other Loan Documents or any of the transactions
contemplated hereby or thereby, contains or will contain a misstatement of
material fact, or omits or will omit to state a material fact required to be
stated in order to make the statements contained herein or therein not
misleading in the light of the circumstances under which such statements were
made.

      6. Extension Fee. In consideration of Lender's agreement to extend the
Maturity Date of the Obligations, Borrower hereby agrees to pay Lender an
extension fee of $50,000 that is deemed fully earned and non-refundable upon

Obligations (the "Extension Fee"). Borrower hereby agrees that the Lender may,
but shall not be obligated to, without further authorization by the Borrower,
pay the Extension Fee directly as an advance under the Loan Agreement on the
dates referenced above.

            may be lifted and that Lender may resell the Stock evidencing the
            Pledged Property immediately without restriction under Rule 144 of
            the Securities Act or state "blue sky" securities laws, and
            replacement of the restricted, legended Stock evidencing the Pledged

<PAGE>   7
         (determined without regard to this proviso) for each such day in such
         Measurement Period or such other period by a fraction, the numerator of
         which shall be the number of shares of Common Stock outstanding at the
         close of business on the earlier of (1) the record date fixed for such
         determination and (2) the date on which ex-dividend trading in the

         warrants) to subscribe for or purchase shares of Common Stock at a

         to this proviso) for any day in such Measurement Period or such other
         period which day is prior to the end of such 45-day period, then the
         Market Price for each such day shall be reduced so that the same shall
         equal the price determined by multiplying the Market Price (determined
         without regard to this proviso) by a fraction, the numerator of which
         shall be the number of shares of Common Stock outstanding at the close
         of business on the record date fixed for the determination of
         stockholders entitled to receive such rights or warrants plus the
         number of shares which the aggregate offering price of the total number
         of shares so offered would purchase at such Market Price, and the
         denominator of which shall be the number of shares of Common Stock
         outstanding on the close of business on such record date plus the total
         number of additional shares of Common Stock so offered for subscription
         or purchase. In determining whether any rights or warrants entitle the
         holders to subscribe for or purchase shares of Common Stock at less
         than the Market Price (determined without regard to this proviso), and
         in determining the aggregate offering price of such shares of Common
         Stock, there shall be taken into account any consideration received for
         such rights or warrants, the value of such consideration, if other than
         cash, to be determined in good faith by a resolution of the Board of
         Directors of the Corporation;

                  (iii)    The outstanding shares of Common Stock shall be
         subdivided into a greater number of shares of Common Stock or a record
         date for any such subdivision shall be fixed, then the Market Price of
         the Common Stock for each day in such Measurement Period or such other
         period which day is prior to the earlier of (1) the day upon which such
         subdivision becomes effective and (2) the date on which ex-dividend
         trading in the Common Stock with respect to such subdivision begins
         shall be proportionately reduced, and conversely, in case the
         outstanding shares of Common Stock shall be combined into a smaller
         number of shares of Common Stock, the Market Price for each day in such
         Measurement Period or such other period which day is prior to the
         earlier of (1) the date on which such combination becomes effective and
         (2) the date on which trading in the Common Stock on a basis which
         gives effect to such combination begins, shall be proportionately
         increased;

                  (iv)     The Corporation shall, by dividend or otherwise,
         distribute to all holders of its Common Stock shares of any class of

         any dividends or distributions to which clause (i) of this proviso
         applies) or evidences of its indebtedness, cash or other assets
         including securities (but excluding any rights or warrants referred to
         in clause (ii) of this proviso, dividends and distributions paid
         exclusively in cash and any capital stock, evidences of indebtedness,
         cash or assets distributed upon a merger or consolidation) (the
         foregoing hereinafter in this clause (iv) of this proviso called the
         "Securities"), or fix a record date for any such distribution, then, in
         each such case, the Market Price for each day in such Measurement
         Period or such other period which day is prior to the earlier of (1)
         the record date for such distribution and (2) the date on which
         ex-dividend trading in the Common Stock with respect to such
         distribution begins shall be reduced so that the same shall be equal to
         the price determined by multiplying the Market Price (determined
         without regard to this proviso) by a fraction, the numerator of which
         shall be the Market Price (determined without regard to this proviso)
         for such date less the fair market value (as determined in good faith
         by resolution of the Board of Directors of the Corporation) on such
         date of the portion of the Securities so distributed or to be
         distributed applicable to one share of Common Stock and the denominator
         of which shall be the Market Price (determined without regard to this
         proviso) for such date; provided, however, that in the event the then
         fair market value (as so determined) of the portion of the Securities
         so distributed applicable to one share of Common Stock is equal to or
         greater than the Market Price (determined without regard to this clause
         (iv) of this proviso) for any such Trading Day, in lieu of the
         foregoing adjustment, adequate provision shall be made so that the
         holders of shares of Series A Convertible Preferred Stock shall have
         the right to receive upon conversion of the shares of Series A
         Convertible Preferred Stock the amount of Securities the holders of
         shares of Series A Convertible Preferred Stock would have received had
         the number of shares of Common Stock to be issued in payment of such
         dividends on the shares of Series A Convertible Preferred Stock been
         issued, or had the holders of shares of Series A Convertible Preferred
         Stock converted the shares of Series A Convertible Preferred Stock, in
         either such case immediately prior to the record date for such
         distribution (provided, however, that if such Securities are not then
         available, the Corporation shall substitute cash or securities or other
         property of equivalent value on terms reasonably satisfactory to the
         holders of shares of Series A Convertible Preferred Stock). If the
         Board of Directors of the Corporation determines the fair market value
         of any distribution for purposes of this clause (iv) by reference to
         the actual or when issued trading market for any securities comprising
         all or part of such distribution, it must in doing so consider the
         prices in such market on the same day for which an adjustment in the
         Market Price is being determined.

                  For purposes of this clause (iv) and clauses (i) and (ii) of
         this proviso, any dividend or distribution to which this clause (iv) is
         applicable that also includes shares of Common Stock, or rights or
         warrants to subscribe for or purchase shares of Common Stock to which
         clause (i) or (ii) of this proviso applies (or both), shall be deemed
         instead to be (1) a dividend or distribution of the evidences of
         indebtedness, assets, shares of capital stock, rights or warrants other
         than such shares of Common Stock or rights or warrants to which clause
         (i) or (ii) of this proviso applies (and any Market Price reduction
         required by this clause (iv) with respect to such dividend or
         distribution shall then be made) immediately followed by (2) a dividend
         or distribution of such shares of Common

                                      -8-
<PAGE>   9
         Stock or such rights or warrants (and any further Market Price
         reduction required by clauses (i) and (ii) of this proviso with respect
         to such dividend or distribution shall then be made), except that any
         shares of Common Stock included in such dividend or distribution shall
         not be deemed "outstanding at the close of business on the date fixed
         for such determination" within the meaning of clause (i) of this
         proviso;

                  (v)      The Corporation or any subsidiary of the Corporation
         shall (x) by dividend or otherwise, distribute to all holders of its
         Common Stock cash in (or fix any record date for any such
         distribution), or (y) repurchase or reacquire shares of its Common
         Stock (other than an Option Share Surrender) for, in either case, an
         aggregate amount that, combined with (1) the aggregate amount of any
         other such distributions to all holders of its Common Stock made
         exclusively in cash after the Issuance Date and within the 12 months
         preceding the date of payment of such distribution, and in respect of
         which no adjustment pursuant to this clause (v) has been made, (2) the
         aggregate amount of any cash plus the fair market value (as determined
         in good faith by a resolution of the Board of Directors of the
         Corporation) of consideration paid in respect of any repurchase or
         other reacquisition by the Corporation or any subsidiary of the
         Corporation of any shares of Common Stock (other than an Option Share
         Surrender) made after the Issuance Date and within the 12 months
         preceding the date of payment of such distribution or making of such
         repurchase or reacquisition, as the case may be, and in respect of
         which no adjustment pursuant to this clause (v) has been made, and (3)
         the aggregate of any cash plus the fair market value (as determined in
         good faith by a resolution of the Board of Directors of the
         Corporation) of consideration payable in respect of any Tender Offer by
         the Corporation or any of its subsidiaries for all or any portion of
         the Common Stock concluded within the 12 months preceding the date of
         payment of such distribution or completion of such repurchase or
         reacquisition, as the case may be, and in respect of which no
         adjustment pursuant to clause (vi) of this proviso has been made (such
         aggregate amount combined with the amounts in clauses (1), (2) and (3)
         above being the "Combined Amount"), exceeds 10% of the product of the
         Market Price (determined without regard to this proviso) for any day in
         such Measurement Period or such other period which day is prior to the
         earlier of (A) the record date with respect to such distribution and
         (B) the date on which ex-dividend trading in the Common Stock with
         respect to such distribution begins or the date of such repurchase or
         reacquisition, as the case may be, times the number of shares of Common
         Stock outstanding on such date, then, and in each such case, the Market
         Price for each such day shall be reduced so that the same shall equal
         the price determined by multiplying the Market Price (determined
         without regard to this proviso) for such day by a fraction (i) the
         numerator of which shall be equal to the Market Price (determined
         without regard to this proviso) for such day less an amount equal to
         the quotient of (x) the excess of such Combined Amount over such 10%
         and (y) the number of shares of Common Stock outstanding on such day
         and (ii) the denominator of which shall be equal to the Market Price
         (determined without regard to this proviso) for such day; provided,
         however, that in the event the portion of the cash so distributed or
         paid for the repurchase or reacquisition of shares (determined per
         share based on the number of shares of Common Stock outstanding)
         applicable to one share of Common Stock is equal to or greater than the
         Market Price (determined without regard to this clause (v) of this
         proviso) of the Common Stock for any such day, then in lieu of the

                                      -9-
<PAGE>   10
         foregoing adjustment with respect to such day, adequate provision shall
         be made so that the holders of shares of Series A Convertible Preferred
         Stock shall have the right to receive upon conversion of shares of
         Series A Convertible Preferred Stock the amount of cash the holders of
         shares of Series A Convertible Preferred Stock would have received had
         the holders of shares of Series A Convertible Preferred Stock converted
         shares of Series A Convertible Preferred Stock immediately prior to the
         record date for such distribution or the payment date of such
         repurchase, as applicable; or

                  (vi)     A Tender Offer made by the Corporation or any of its
         subsidiaries for all or any portion of the Common Stock shall expire
         and such Tender Offer (as amended upon the expiration thereof) shall
         require the payment to stockholders (based on the acceptance (up to any
         maximum specified in the terms of the Tender Offer) of Purchased Shares
         (as defined below)) of an aggregate consideration having a fair market
         value (as determined in good faith by resolution of the Board of
         Directors of the Corporation) that combined together with (1) the
         aggregate of the cash plus the fair market value (as determined in good
         faith by a resolution of the Board of Directors of the Corporation), as
         of the expiration of such Tender Offer, of consideration paid or
         payable in respect of any other Tender Offers by the Corporation or any
         of its subsidiaries for all or any portion of the Common Stock expiring
         within the 12 months preceding the expiration of such Tender Offer and
         in respect of which no adjustment pursuant to this clause (vi) has been
         made, (2) the aggregate amount of any cash plus the fair market value
         (as determined in good faith by a resolution of the Board of Directors
         of the Corporation) of consideration paid in respect of any repurchase
         or other reacquisition by the Corporation or any subsidiary of the
         Corporation of any shares of Common Stock (other than an Option Share
         Surrender) made after the Issuance Date and within the 12 months
         preceding the expiration of such Tender Offer and in respect of which
         no adjustment pursuant to clause (v) of this proviso has been made, and
         (3) the aggregate amount of any distributions to all holders of Common
         Stock made exclusively in cash within 12 months preceding the
         expiration of such Tender Offer and in respect of which no adjustment
         pursuant to clause (v) of this proviso has been made, exceeds 10% of
         the product of the Market Price (determined without regard to this
         proviso) for any day in such period times the number of shares of
         Common Stock outstanding on such day, then, and in each such case, the
         Market Price for such day shall be reduced so that the same shall equal
         the price determined by multiplying the Market Price (determined
         without regard to this proviso) for such day by a fraction, the
         numerator of which shall be the number of shares of Common Stock
         outstanding on such day multiplied by the Market Price (determined
         without regard to this proviso) for such day and the denominator of
         which shall be the sum of (x) the fair market value (determined as
         aforesaid) of the aggregate consideration paid or payable to
         stockholders based on the acceptance (up to any maximum specified in
         the terms of the Tender Offer) of all shares validly tendered and not
         withdrawn as of the last time tenders could have been made pursuant to
         such Tender Offer (the "Expiration Time") (the shares deemed so
         accepted, up to any such maximum, being referred to as the "Purchased
         Shares") and (y) the product of the number of shares of Common Stock
         outstanding (less any Purchased Shares) on such day times the Market
         Price (determined without regard to this proviso) of the Common Stock
         on the Trading Day next succeeding the Expiration Time.

successor, replacement or similar provision thereof or of any other market on
which the Common Stock is listed for trading.

                  "Subscription Agreements" means the several Subscription

                  "Trading Day" means a day on whichever of (x) the national

time constitutes the principal securities market for the Common Stock, is open

                  "Transfer Agent Agreement" means the Transfer Agent Agreement,

                  "Warrants" means the Common Stock Purchase Warrants issued by
the Corporation in connection with the issuance of the shares of Series A
Convertible Preferred Stock.

                  SECTION 2.        DESIGNATION AND AMOUNT. The shares of such
series shall be designated as "Series A Convertible Preferred Stock", and the
number of shares constituting the Series A Convertible Preferred Stock shall be
4,000, and shall not be subject to increase. The Corporation shall not issue any
shares of Series A Convertible Preferred Stock other than pursuant to the
Subscription Agreements, unless such issuance shall have been approved by the
Majority Holders. Any shares of Series A Convertible Preferred Stock which are
redeemed by the Corporation and retired and any shares of Series A Convertible
Preferred Stock which are converted in accordance with Section 10 shall be
restored to the status of authorized, unissued and undesignated shares of the
Corporation's class of Preferred Stock and shall not be subject to issuance, and
may not thereafter be outstanding, as shares of Series A Convertible Preferred
Stock.

                  SECTION 3.        [RESERVED.]

                  SECTION 4.        RANK. Subject to Section 12(b), all Series A
Convertible Preferred Stock shall rank (i) senior to the Common Stock, now or
hereafter issued, as to payment of dividends and distribution of assets upon
liquidation, dissolution, or winding up of the Corporation, whether voluntary
or involuntary, (ii) senior to any additional series of the class of Preferred
Stock which series the Board of Directors may from time to time authorize, both
as to payment of dividends and as to distributions of assets upon liquidation,
dissolution, or winding

                                      -15-
<PAGE>   16
up of the Corporation, whether voluntary or involuntary, and (iii) senior to any
additional class of preferred stock (or series of preferred stock of such class)
which the Board of Directors or the stockholders may from time to time authorize
in accordance herewith.

                  SECTION 5.        DIVIDENDS AND DISTRIBUTIONS. (a) The holders
of shares of Series A Convertible Preferred Stock shall be entitled to receive,
when, as, and if declared by the Board of Directors out of funds legally
available for such purpose, dividends at the rate of $60.00 per annum per share,
and no more, which shall be fully cumulative, shall accrue without interest
(except as otherwise provided herein as to dividends in arrears) from the date
of original issuance of each share of Series A Convertible Preferred Stock and
shall be payable quarterly on March 1, June 1, September 1 and December 1 of
each year commencing December 1, 1999 (except that if any such date is a
Saturday, Sunday, or legal holiday, then such dividend shall be payable on the
next succeeding day that is not a Saturday, Sunday, or legal holiday) to holders
of record as they appear on the stock books of the Corporation on such record
dates, which record dates must be not more than 20 nor less than 10 days
preceding the payment dates for such dividends, as shall be fixed by the Board.
Dividends on the Series A Convertible Preferred Stock shall be paid in cash or,
in lieu of paying such dividends and subject to the limitations in Section 5(b)
hereof, the amount of such dividends shall be included in the Accrual Amount for
each share, at the option of the Corporation as hereinafter provided. The amount
of the dividends payable per share of Series A Convertible Preferred Stock for
each quarterly dividend period shall be computed by dividing the annual dividend
amount by four. The amount of dividends payable for the initial dividend period
and any period shorter than a full quarterly dividend period shall be computed
on the basis of a 360-day year of twelve 30-day months. Dividends required to be
paid in cash pursuant to Section 5(b) which are not paid on a payment date,
whether or not such dividends have been declared, will bear interest at the rate
of 14% per annum until paid (or such lesser rate as shall be the maximum rate
allowable by applicable law). No dividends or other distributions, other than
the dividends payable solely in shares of any Junior Dividend Stock, shall be
paid or set apart for payment on any shares of Junior Dividend Stock, and no
purchase, redemption, or other acquisition shall be made by the Corporation of
any shares of Junior Dividend Stock (except for Option Share Surrenders), unless
and until all accrued and unpaid cash dividends on the Series A Convertible
Preferred Stock and interest on dividends in arrears at the rate specified
herein shall have been paid or declared and set apart for payment.

                  If at any time any dividend on any Senior Dividend Stock shall
be in arrears, in whole or in part, no dividend shall be paid or declared and
set apart for payment on the Series A Convertible Preferred Stock unless and
until all accrued and unpaid dividends with respect to the Senior Dividend
Stock, including the full dividends for the then current dividend period, shall
have been paid or declared and set apart for payment, without interest. No full
dividends shall be paid or declared and set apart for payment on any Parity
Dividend Stock for any period unless all accrued but unpaid dividends (and
interest on dividends in arrears at the rate specified herein) have been, or
contemporaneously are, paid or declared and set apart for such payment on the
Series A Convertible Preferred Stock. No full dividends shall be paid or
declared and set apart for payment on the Series A Convertible Preferred Stock
for any period unless all accrued but unpaid dividends have been, or
contemporaneously are, paid or declared and set apart for payment on the Parity
Dividend Stock for all dividend periods terminating on or prior to the date of
payment of such full dividends. When dividends are not paid in full upon the
Series A

                                      -16-
<PAGE>   17
Convertible Preferred Stock and the Parity Dividend Stock, all dividends paid or
declared and set apart for payment upon shares of Series A Convertible Preferred
Stock (and interest on dividends in arrears at the rate specified herein) and
the Parity Dividend Stock shall be paid or declared and set apart for payment
pro rata, so that the amount of dividends paid or declared and set apart for
payment per share on the Series A Convertible Preferred Stock and the Parity
Dividend Stock shall in all cases bear to each other the same ratio that accrued
and unpaid dividends per share on the shares of Series A Convertible Preferred
Stock and the Parity Dividend Stock bear to each other.

                  Any references to "distribution" contained in this Section 5
shall not be deemed to include any stock dividend or distributions made in
connection with any liquidation, dissolution, or winding up of the Corporation,
whether voluntary or involuntary.

                  (b)      If (x) prior to any dividend payment date the
Corporation notifies the holders of Series A Convertible Preferred Stock that
the dividends with respect to such date will be paid in cash or (y) on any
dividend payment date the Corporation is not in compliance in all material
respects with its obligations to the holders of the Series A Convertible
Preferred Stock (including, without limitation, its obligations under the
Subscription Agreements, the Registration Rights Agreements, the Warrants and
this Certificate of Designations) and such noncompliance continues for a period
of ten days after notice thereof is given to the Corporation by any holder of
Series A Convertible Preferred Stock, such dividends must be timely paid in
cash. If clauses (x) or (y) of the foregoing sentence do not apply on any
dividend payment date, the Corporation may, but shall not be required to, pay
the applicable dividends in cash. The amount of any dividends not paid in cash
shall be included in the Accrual Amount for each share of Series A Convertible
Preferred Stock.

                  (c)      Neither the Corporation nor any subsidiary of the
Corporation shall redeem, repurchase or otherwise acquire in any one transaction
or series of related transactions any shares of Common Stock, Junior Dividend
Stock or Junior Liquidation Stock if the number of shares so repurchased,
redeemed or otherwise acquired in such transaction or series of related
transactions (excluding any Option Share Surrender) is more than 10% of the
number of shares of Common Stock, Junior Dividend Stock or Junior Liquidation
Stock, as the case may be, outstanding immediately prior to such transaction or
series of related transactions unless the Corporation or such subsidiary offers
to purchase for cash from each holder of shares of Series A Convertible
Preferred Stock at the time of such redemption, repurchase or acquisition the
same percentage of such holder's shares of Series A Convertible Preferred Stock
as the percentage of the number of outstanding shares of Common Stock, Junior
Dividend Stock or Junior Liquidation Stock, as the case may be, to be so
redeemed, repurchased or acquired at a purchase price per share of Series A
Convertible Preferred Stock equal to the greater of (i) the Premium Price in
effect on the date of purchase pursuant to this Section 5(c) and (ii) the
Converted Market Price on the date of purchase pursuant to this Section 5(c).

                  (d)      Neither the Corporation nor any subsidiary of the
Corporation shall (1) make any Tender Offer for 10% or more of the outstanding
shares of Common Stock, unless the Corporation contemporaneously therewith makes
an offer, or (2) enter into an agreement regarding such a Tender Offer for
outstanding shares of Common Stock by any person other than

                                      -17-
<PAGE>   18
the Corporation or any subsidiary of the Corporation, unless such person agrees
with the Corporation to make an offer, in either such case to each holder of
outstanding shares of Series A Convertible Preferred Stock to purchase for cash
at the time of purchase in such Tender Offer the same percentage of shares of
Series A Convertible Preferred Stock held by such holder as the percentage of
outstanding shares of Common Stock actually purchased in such Tender Offer at a
price per share of Series A Convertible Preferred Stock equal to the greater of
(i) the Premium Price in effect on the date of purchase pursuant to this Section
5(d) and (ii) the Converted Market Price on the date of purchase pursuant to
this Section 5(d).

                  SECTION 6.        LIQUIDATION PREFERENCE. In the event of a
liquidation, dissolution, or winding up of the Corporation, whether voluntary or
involuntary, the holders of Series A Convertible Preferred Stock shall be
entitled to receive out of the assets of the Corporation, whether such assets
constitute stated capital or surplus of any nature, an amount per share of
Series A Convertible Preferred Stock equal to the Liquidation Preference, and no
more, before any payment shall be made or any assets distributed to the holders
of Junior Liquidation Stock; provided, however, that such rights shall accrue to
the holders of Series A Convertible Preferred Stock only in the event that the
Corporation's payments with respect to the liquidation preference of the holders
of Senior Liquidation Stock are fully met. After the liquidation preferences of
the Senior Liquidation Stock are fully met, the entire assets of the Corporation
available for distribution shall be distributed ratably among the holders of the
Series A Convertible Preferred Stock and any Parity Liquidation Stock in
proportion to the respective preferential amounts to which each is entitled (but
only to the extent of such preferential amounts). After payment in full of the
liquidation price of the shares of the Series A Convertible Preferred Stock and
the Parity Liquidation Stock, the holders of such shares shall not be entitled
to any further participation in any distribution of assets by the Corporation.
Neither a consolidation or merger of the Corporation with another corporation
nor a sale or transfer of all or part of the Corporation's assets for cash,
securities, or other property in and of itself will be considered a liquidation,
dissolution or winding up of the Corporation.

                  SECTION 7.        MAXIMUM SHARE AMOUNT REDEMPTION.

                  (a)      REDEMPTION BASED ON MAXIMUM SHARE AMOUNT. (1)
Notwithstanding any other provision herein, unless the Stockholder Approval
shall have been obtained from the stockholders of the Corporation or waived by
the Nasdaq, the Nasdaq SmallCap, or other securities market on which the Common
Stock is then listed, so long as the Common Stock is listed on the Nasdaq, the
Nasdaq SmallCap, the NYSE or the AMEX the Corporation shall not be required to
issue upon conversion of shares of Series A Convertible Preferred Stock pursuant
to Section 10 more than the Maximum Share Amount. The Maximum Share Amount shall
be allocated among the shares of Series A Convertible Preferred Stock at the
time of initial issuance thereof pro rata based on the initial issuance of 4,000
shares of Series A Convertible Preferred Stock. Each certificate for shares of
Series A Convertible Preferred Stock initially issued shall bear a notation as
to the number of shares constituting the portion of the Maximum Share Amount
allocated to the shares of Series A Convertible Preferred Stock represented by
such certificate for purposes of conversion thereof. Upon surrender of any
certificate for shares of Series A Convertible Preferred Stock for transfer or
re-registration thereof (or, at the option of the holder, for conversion
pursuant to Section 10(a) of less than all of the shares of Series A

                                      -18-
<PAGE>   19
Convertible Preferred Stock represented thereby), the Corporation shall make a
notation on the new certificate issued upon such transfer or re-registration or
evidencing such unconverted shares, as the case may be, as to the remaining
number of shares of Common Stock from the Maximum Share Amount remaining
available for conversion of the shares of Series A Convertible Preferred Stock
evidenced by such new certificate. If any certificate for shares of Series A
Convertible Preferred Stock is surrendered for split-up into two or more
certificates representing an aggregate number of shares of Series A Convertible
Preferred Stock equal to the number of shares of Series A Convertible Preferred
Stock represented by the certificate so surrendered (as reduced by any
contemporaneous conversion of shares of Series A Convertible Preferred Stock
represented by the certificate so surrendered), each certificate issued on such
split-up shall bear a notation of the portion of the Maximum Share Amount
allocated thereto determined by pro rata allocation from among the remaining
portion of the Maximum Share Amount allocated to the certificate so surrendered.
If any shares of Series A Convertible Preferred Stock represented by a single
certificate are converted in full pursuant to Section 10, all of the portion of
the Maximum Share Amount allocated to such shares of Series A Convertible
Preferred Stock which remains unissued after such conversion shall be
re-allocated pro rata to the outstanding shares of Series A Convertible
Preferred Stock held of record by the holder of record at the close of business
on the date of such conversion of the shares of Series A Convertible Preferred
Stock so converted, and if there shall be no other shares of Series A
Convertible Preferred Stock held of record by such holder at the close of
business on such date, then such portion of the Maximum Share Amount shall be
allocated pro rata among the shares of Series A Convertible Preferred Stock
outstanding on such date.

                  (2)      The Corporation shall promptly, but in no event later
than five Business Days after the occurrence, give notice to each holder of
shares of Series A Convertible Preferred Stock (by telephone line facsimile
transmission at such number as such holder has specified in writing to the
Corporation for such purposes or, if such holder shall not have specified any
such number, by overnight courier or first class mail, postage prepaid, at such
holder's address as the same appears on the stock books of the Corporation) and
any holder of shares of Series A Convertible Preferred Stock may at any time
after the occurrence give notice to the Corporation, in either case, if on any
ten Trading Days within any period of 20 consecutive Trading Days the
Corporation would not have been required to convert shares of Series A
Convertible Preferred Stock of such holder in accordance with Section 10(a) as a
consequence of the limitations set forth in Section 7(a)(1) had the shares of
Series A Convertible Preferred Stock held by such holder been converted in full
into Common Stock on each such day, determined without regard to the limitation,
if any, on such holder contained in the proviso to the second sentence of
Section 10(a) (any such notice, whether given by the Corporation or a holder, an
"Inconvertibility Notice"). If the Corporation shall have given or been required
to give any Inconvertibility Notice, or if a holder shall have given any
Inconvertibility Notice, then within ten Trading Days after such
Inconvertibility Notice is given or was required to be given, the holder
receiving or giving, as the case may be, such Inconvertibility Notice shall have
the right by written notice to the Corporation (which written notice may be
contained in the Inconvertibility Notice given by such holder) to direct the
Corporation to redeem the portion of such holder's outstanding shares of Series
A Convertible Preferred Stock (which, if applicable, shall be all of such
holder's outstanding shares of Series A Convertible Preferred Stock) as shall
not, on the Business Day prior to the date of such redemption, be convertible
into shares of

                                      -19-
<PAGE>   20
Common Stock by reason of the limitations set forth in Section 7(a)(1)
(determined without regard to the limitation, if any, on beneficial ownership of
Common Stock by such holder contained in the proviso to the second sentence of
Section 10(a)), within 15 Trading Days after such holder so directs the
Corporation, at a price per share equal to the Share Limitation Redemption
Price. If a holder of shares of Series A Convertible Preferred Stock directs the
Corporation to redeem outstanding shares of Series A Convertible Preferred Stock
and, prior to the date the Corporation is required to redeem such shares of
Series A Convertible Preferred Stock, the Corporation would have been able,
within the limitations set forth in Section 7(a)(1), to convert all of such
holder's shares of Series A Convertible Preferred Stock (determined without
regard to the limitation, if any, on beneficial ownership of shares of Common
Stock by such holder contained in the proviso to the second sentence of Section
10(a)) on any ten Trading Days within any period of 15 consecutive Trading Days
commencing after the period of 20 consecutive Trading Days which gave rise to
the applicable Inconvertibility Notice from the Corporation or such holder of
shares of Series A Convertible Preferred Stock, as the case may be, had all of
such holder's shares of Series A Convertible Preferred Stock been surrendered
for conversion into Common Stock on each of such ten Trading Days within such 15
Trading Day period, then the Corporation shall not be required to redeem any
shares of Series A Convertible Preferred Stock by reason of such
Inconvertibility Notice.

                  (3)      Notwithstanding the giving of any Inconvertibility
Notice by the Corporation to the holders of Series A Convertible Preferred Stock
pursuant to Section 7(a)(2) or the giving or the absence of any notice by the
holders of the Series A Convertible Preferred Stock in response thereto or any
redemption of shares of Series A Convertible Preferred Stock pursuant to Section
7(a)(2), thereafter the provisions of Section 7(a)(2) shall continue to be
applicable on any occasion unless the Stockholder Approval shall have been
obtained from the stockholders of the Corporation or waived by the Nasdaq, the
Nasdaq SmallCap, or other securities market on which the Common Stock is then
listed.

                  (4)      On each Share Limitation Redemption Date (or such
later date as a holder of shares of Series A Convertible Preferred Stock shall
surrender to the Corporation the certificate(s) for the shares of Series A
Convertible Preferred Stock being redeemed pursuant to this Section 7(a)), the
Corporation shall make payment in immediately available funds of the applicable
Share Limitation Redemption Price to such holder of shares of Series A
Convertible Preferred Stock to be redeemed to or upon the order of such holder
as specified by such holder in writing to the Corporation at least one Business
Day prior to such Share Limitation Redemption Date. Upon redemption of less than
all of the shares of Series A Convertible Preferred Stock evidenced by a
particular certificate, promptly, but in no event later than three Business Days
after surrender of such certificate to the Corporation, the Corporation shall
issue a replacement certificate for the shares of Series A Convertible Preferred
Stock evidenced by such certificate which have not been redeemed. Only whole
shares of Series A Convertible Preferred Stock may be redeemed.

                  (5)      (A)      Notwithstanding any other provision of this
Certificate of Designations, if an Inconvertibility Day occurs by reason of
events which are not solely within the control of the Corporation, the
Corporation shall have the right to give a Control Notice to the holders of
Series A Convertible Preferred Stock at any time after such Inconvertibility Day

                                      -20-
<PAGE>   21
occurs and prior to the earlier of (1) the date on which all holders of shares
of Series A Convertible Preferred Stock who had the right (other than as limited
by this Section 7(a)(5)) to require redemption of any shares of Series A
Convertible Preferred Stock by reason of the occurrence of such Inconvertibility
Day no longer have such right and (2) the applicable Share Limitation Redemption
Date by reason of the earliest notice given by any holder of shares of Series A
Convertible Preferred Stock directing the Corporation to redeem such shares in
accordance with Section 7(a)(2) by reason of such Inconvertibility Day. For
purposes of this Section 7(a)(5), an Inconvertibility Day shall be deemed to
have occurred by reason of events which are not solely within the control of the
Corporation if a requirement of the Corporation to redeem, or a right of any
holder of shares of Series A Convertible Preferred Stock to require redemption
of, shares of Series A Convertible Preferred Stock by reason thereof would
result in the Corporation being required to classify the Series A Convertible
Preferred Stock as redeemable preferred stock on a balance sheet of the
Corporation prepared in accordance with Generally Accepted Accounting Principles
and Regulation S-X of the SEC. If the Corporation timely gives a Control Notice
to the holders of shares of Series A Convertible Preferred Stock, then in lieu
of payment of the Share Limitation Redemption Price pursuant to a redemption
notice given by any holder of shares of Series A Convertible Preferred Stock in
accordance with Section 7(a)(2) by reason of such Inconvertibility Day and
commencing on such Inconvertibility Day the Conversion Price for all outstanding
shares of Series A Convertible Preferred Stock will be 80% of the amount the
Conversion Price would otherwise be. Such adjustment of the Conversion Price
shall continue in effect until the earliest of (x) the date which is 90 days
after the Stockholder Approval shall have been obtained from the stockholders of
the Corporation or waived by the Nasdaq SmallCap or other securities market on
which the Common Stock is then listed, (y) the date any further adjustments are
made following a failure to obtain the Stockholder Approval as provided below,
and (z) the date when shares of Series A Convertible Preferred Stock are no
longer outstanding. On or after the date the Corporation gives such Control
Notice, upon notice from the Majority Holders, the Corporation promptly shall
call a special meeting of its stockholders, to be held not later than 90 days
after such notice is given, to seek the Stockholder Approval for the issuance of
all shares of Common Stock issuable upon conversion of the Series A Convertible
Preferred Stock in accordance with Section 10 and shall use its best efforts to
obtain the Stockholder Approval. The Corporation shall prepare and file with the
SEC within 20 days after such notice is given preliminary proxy materials which
set forth a proposal to seek such Stockholder Approval. The Corporation shall
provide the Majority Holders an opportunity to consult with the Corporation
regarding the content of such proxy materials insofar as it relates to the
Stockholder Approval by providing copies of such preliminary proxy materials and
any revised preliminary proxy materials to the Majority Holders a reasonable
period of time prior to their filing with the SEC. The Corporation shall furnish
to each holder of shares of Series A Convertible Preferred Stock a copy of its
definitive proxy materials for such special meeting and any amendments or
supplements thereto promptly after the same are mailed to stockholders or filed
with the SEC. Upon the earlier of (i) the failure to obtain the Stockholder
Approval at the special meeting or (ii) the failure to hold the special meeting
within such 90-day period, the Corporation shall so notify the holders of shares
of Series A Convertible Preferred Stock and such of the following as shall be
specified by notice to the Corporation from the Majority Holders shall occur:
(1) commencing on the Business Day following the Corporation's receipt of such
notice, the Conversion Price of the outstanding shares of Series A Convertible
Preferred Stock will be 60% of the amount the Conversion Price would otherwise
be without

                                      -21-
<PAGE>   22
regard to other adjustments pursuant to this Section 7(a)(5) or Section 11(b)(4)
and (2) the Corporation shall promptly file applications and take all other
actions necessary to (i) list the Common Stock for trading and quotation on the
OTC Bulletin Board or such other securities market or exchange which will not
restrict the number of shares of Common Stock issuable upon conversion of the
Series A Convertible Preferred Stock and (ii) upon filing such applications,
request the immediate removal of the Common Stock from listing on the securities
market on which it is then listed which restricts the issuance of shares of
Common Stock upon conversion of shares of Series A Convertible Preferred Stock
without the Stockholder Approval.

                  (B)      If and for so long as an adjustment of the Conversion
Price is simultaneously required by this Section 7(a)(5) and by Section
11(b)(4), the applicable Conversion Price shall be the lower of the two amounts
required by each such section.

                  (C)      The rights of holders of shares of Series A
Convertible Preferred Stock to require redemption of their shares and exercise
other rights pursuant to Sections 7(a)(1) through 7(a)(4) by reason of an
Inconvertibility Day as to which the Corporation does not have a right to give a
Control Notice, or fails to exercise such right on a timely basis, shall not be
limited by the operation of this Section 7(a)(5).

                  (b)      NO OTHER REDEMPTION.  The shares of Series A
Convertible Preferred Stock shall not be subject to redemption by the
Corporation at the option of the Holders except as provided in this Section 7
and in Section 11.

                  SECTION 8.        NO SINKING FUND.  The shares of Series A
Convertible Preferred Stock shall not be subject to the operation of a
purchase, retirement or sinking fund.

                  SECTION 9.        OPTIONAL REDEMPTION.

                  (a)      CORPORATION OPTIONAL REDEMPTION. If (1) the
Corporation shall be in compliance in all material respects with its obligations
to the holders of shares of Series A Convertible Preferred Stock (including,
without limitation, its obligations under the Subscription Agreements, the
Registration Rights Agreements, the Warrants and the provisions of this
Certificate of Designations), (2) on the date the Corporation Optional
Redemption Notice is given and at all times until the Redemption Date, the
Registration Statement is effective and available for use by each holder of
shares of Series A Convertible Preferred Stock for the resale of shares of
Common Stock acquired by such holder upon conversion of all shares of Series A
Convertible Preferred Stock held by such holder and (3) no Optional Redemption
Event shall have occurred with respect to which, on the date a Corporation
Optional Redemption Notice is to be given or on the Redemption Date, any holder
of shares of Series A Convertible Preferred Stock (A) shall be entitled to
exercise optional redemption rights under Section 11 by reason of such Optional
Redemption Event or (B) shall have exercised optional redemption rights under
Section 11 by reason of such Optional Redemption Event and the Corporation shall
not have paid the Optional Redemption Price to such holder, then the Corporation
shall have the right, exercisable by giving a Corporation Optional Redemption
Notice not less than 30 days or more than 50 days prior to the Redemption Date
to all holders of record of the shares of Series A Convertible Preferred Stock,
at any time to redeem all or from time to time to redeem any part of

                                      -22-
<PAGE>   23
the outstanding shares of Series A Convertible Preferred Stock in accordance
with this Section 9(a). If the Corporation shall redeem less than all
outstanding shares of Series A Convertible Preferred Stock, such redemption
shall be made as nearly as practical pro rata from all holders of shares of
Series A Convertible Preferred Stock. Any Corporation Optional Redemption Notice
under this Section 9(a) shall be given to the holders of record of the shares of
Series A Convertible Preferred Stock at their addresses appearing on the records
of the Corporation; provided, however, that any failure or defect in the giving
of such notice to any such holder shall not affect the validity of notice to or
the redemption of shares of Series A Convertible Preferred Stock of any other
holder. On the Redemption Date (or such later date as a holder of shares of
Series A Convertible Preferred Stock surrenders to the Corporation the
certificate(s) for shares of Series A Convertible Preferred Stock to be redeemed
pursuant to this Section 9(a)), the Corporation shall make payment of the
applicable Redemption Price to each holder of shares of Series A Convertible
Preferred Stock to be redeemed in immediately available funds to such account as
specified by such holder in writing to the Corporation at least one Business Day
prior to the Redemption Date. A holder of shares of Series A Convertible
Preferred Stock to be redeemed pursuant to this Section 9(a) shall be entitled
to convert such shares of Series A Convertible Preferred Stock in accordance
with Section 10 (x) through the day prior to the Redemption Date and (y) if the
Corporation shall fail to pay the Redemption Price of any share of Series A
Convertible Preferred Stock when due, at any time after the due date thereof
until such date as the Corporation pays the Redemption Price of such share of
Series A Convertible Preferred Stock. No share of Series A Convertible Preferred
Stock as to which the holder exercises the right of conversion pursuant to
Section 10 or the optional redemption right pursuant to Section 11 may be
redeemed by the Corporation pursuant to this Section 9(a) on or after the date
of exercise of such conversion right or optional redemption right, as the case
may be, regardless of whether the Corporation Optional Redemption Notice shall
have been given prior to, or on or after, the date of exercise of such
conversion right or optional redemption right, as the case may be.

                  (b)      FINAL REDEMPTION. The Corporation shall have the
right to redeem all, but not less than all, outstanding shares of Series A
Convertible Preferred Stock at any time on or after the third anniversary of the
Issuance Date so long as (1) the Corporation shall be in compliance in all
material respects with its obligations to the holders of the Series A
Convertible Preferred Stock (including, without limitation, its obligations
under the Subscription Agreements, the Registration Rights Agreements, the
Warrants and this Certificate of Designations) and (2) no Optional Redemption
Event shall have occurred with respect to which on the date a Final Redemption
Notice is to be given or on the Final Redemption Date, any holder of shares of
Series A Convertible Preferred Stock (a) shall be entitled to exercise optional
redemption rights under Section 11 by reason of such Optional Redemption Event
or (b) shall have exercised optional redemption rights under Section 11 by
reason of such Optional Redemption Event and the Corporation shall not have paid
the Optional Redemption Price to such holder. In order to exercise its rights
under this Section 9(b), the Corporation shall give a Final Redemption Notice
not less than 30 days or more than 50 days prior to the Final Redemption Date to
all holders of record of the shares of Series A Convertible Preferred Stock. Any
Final Redemption Notice shall be given to the holders of record of the shares of
Series A Convertible Preferred Stock by telephone line facsimile transmission to
such number as shown on the records of the Corporation for such purpose;
provided, however, that any failure or defect

                                      -23-
<PAGE>   24
in the giving of such notice to any such holder shall not affect the validity of
notice to or the redemption of shares of Series A Convertible Preferred Stock of
any other holder. On the Final Redemption Date (or such later date as a holder
of shares of Series A Convertible Preferred Stock surrenders to the Corporation
the certificate(s) for shares of Series A Convertible Preferred Stock to be
redeemed pursuant to this Section 9(b)), the Corporation shall make payment of
the applicable Final Redemption Price to each holder of shares of Series A
Convertible Preferred Stock to be redeemed in immediately available funds to
such account as specified by such holder in writing to the Corporation at least
one Business Day prior to the Final Redemption Date. A holder of shares of
Series A Convertible Preferred Stock to be redeemed pursuant to this Section
9(b) shall be entitled to convert such shares of Series A Convertible Preferred
Stock in accordance with Section 10 (x) through the day prior to the Final
Redemption Date and (y) if the Corporation shall fail to pay the Final
Redemption Price of any share of Series A Convertible Preferred Stock when due,
at any time after the due date thereof until such date as the Corporation pays
the Final Redemption Price of such share of Series A Convertible Preferred Stock
to such holder. No share of Series A Convertible Preferred Stock as to which a
holder exercises the right of conversion pursuant to Section 10 or the optional
redemption right pursuant to Section 11 may be redeemed by the Corporation
pursuant to this Section 9(b) on or after the date of exercise of such
conversion right or optional redemption right, as the case may be, regardless of
whether the Final Redemption Notice shall have been given prior to, or on or
after, the date of exercise of such conversion right or optional redemption
right, as the case may be.

                  (C)      NO OTHER OPTIONAL REDEMPTION.  The shares of Series
A Convertible Preferred Stock shall not be subject to redemption at the option
of the Corporation except as provided in Sections 9(a) and 9(b).

                  SECTION 10.       CONVERSION.

                  (a)      CONVERSION AT OPTION OF HOLDER. The holders of the
Series A Convertible Preferred Stock may at any time on or after the Issuance
Date convert at any time all or from time to time any part of their shares of
Series A Convertible Preferred Stock into fully paid and nonassessable shares of
Common Stock and such other securities and property as herein provided. Each
share of Series A Convertible Preferred Stock may be converted at the office of
the Conversion Agent or at such other additional office or offices, if any, as
the Board of Directors may designate, into such number of fully paid and
nonassessable shares of Common Stock (calculated as to each conversion to the
nearest 1/100th of a share) determined by dividing (x) the sum of (i) the
Conversion Amount, (ii) an amount equal to the Accrual Amount on the share of
Series A Convertible Preferred Stock being converted to the applicable
Conversion Date, and (iii) accrued but unpaid interest on the dividends required
to be paid in cash on the share of Series A Convertible Preferred Stock being
converted in arrears to the applicable Conversion Date at the rate provided in
Section 5 by (y) the Conversion Price for such Conversion Date (the "Conversion
Rate"); provided, however, that in no event shall any holder of shares of Series
A Convertible Preferred Stock be entitled to convert any shares of Series A
Convertible Preferred Stock in excess of that number of shares of Series A
Convertible Preferred Stock upon conversion of which the sum of (1) the number
of shares of Common Stock beneficially owned by such holder and all Aggregated
Persons of such holder (other than shares of Common Stock deemed beneficially
owned through the ownership of (x) unconverted shares

                                      -24-
<PAGE>   25
of Series A Convertible Preferred Stock and (y) the unconverted or unexercised
portion of any instrument, including without limitation the Warrants, which
contains limitations similar to those set forth in this sentence) and (2) the
number of shares of Common Stock issuable upon the conversion of the number of
shares of Series A Convertible Preferred Stock with respect to which the
determination in this proviso is being made, would result in beneficial
ownership by such holder and all Aggregated Persons of such holder of more than
4.9% of the outstanding shares of Common Stock. For purposes of the proviso to
the immediately preceding sentence, beneficial ownership shall be determined in
accordance with Section 13(d) of the Exchange Act and Regulation 13D-G
thereunder, except as otherwise provided in clause (1) of the proviso to the
immediately preceding sentence.

                  (b)      OTHER PROVISIONS. (1) Notwithstanding anything in
this Section 10(b) to the contrary, no change in the Conversion Amount pursuant
to this Section 10(b) shall actually be made until the cumulative effect of the
adjustments called for by this Section 10(b) since the date of the last change
in the Conversion Amount would change the Conversion Amount by more than 1%.
However, once the cumulative effect would result in such a change, then the
Conversion Amount shall actually be changed to reflect all adjustments called
for by this Section 10(b) and not previously made. Notwithstanding anything in
this Section 10(b), no change in the Conversion Amount shall be made that would
result in the price at which a share of Series A Convertible Preferred Stock is
converted being less than the par value of the Common Stock into which shares of
Series A Convertible Preferred Stock are at the time convertible.

                  (2)      The holders of shares of Series A Convertible
Preferred Stock at the close of business on the record date for any dividend
payment to holders of Series A Convertible Preferred Stock shall be entitled to
receive the dividend payable on such shares on the corresponding dividend
payment date notwithstanding the conversion thereof after such dividend payment
record date or the Corporation's default in payment of the dividend due on such
dividend payment date; provided, however, that the holder of shares of Series A
Convertible Preferred Stock surrendered for conversion during the period between
the close of business on any record date for a dividend payment and the opening
of business on the corresponding dividend payment date must pay to the
Corporation, within five days after receipt by such holder, an amount equal to
the dividend payable on such shares on such dividend payment date if such
dividend is paid by the Corporation to such holder. A holder of shares of Series
A Convertible Preferred Stock on a record date for a dividend payment who (or
whose transferee) tenders any of such shares for conversion into shares of
Common Stock on or after such dividend payment date will receive the dividend
payable by the Corporation on such shares of Series A Convertible Preferred
Stock on such date, and the converting holder need not make any payment of the
amount of such dividend in connection with such conversion of shares of Series A
Convertible Preferred Stock. Except as provided above, no adjustment shall be
made in respect of cash dividends on Common Stock or Series A Convertible
Preferred Stock that may be accrued and unpaid at the date of surrender of
shares of Series A Convertible Preferred Stock.

                  (3)      (A)      The right of the holders of Series A
Convertible Preferred Stock to convert their shares shall be exercised by giving
(which may be done by telephone line facsimile transmission) a Conversion Notice
to the Conversion Agent, with a copy to the Corporation. If a holder of Series A
Convertible Preferred Stock elects to convert any shares of Series A

                                      -25-
<PAGE>   26
Convertible Preferred Stock in accordance with Section 10(a), such holder shall
not be required to surrender the certificate(s) representing such shares of
Series A Convertible Preferred Stock to the Corporation unless all of the shares
of Series A Convertible Preferred Stock represented thereby are so converted.
Each holder of shares of Series A Convertible Preferred Stock and the
Corporation shall maintain records showing the number of shares so converted and
the dates of such conversions or shall use such other method, satisfactory to
such holder and the Corporation, so as to not require physical surrender of such
certificates upon each such conversion. In the event of any dispute or
discrepancy, such records of the Corporation shall be controlling and
determinative in the absence of manifest error. Notwithstanding the foregoing,
if any shares of Series A Convertible Preferred Stock evidenced by a particular
certificate therefor are converted as aforesaid, the holder of Series A
Convertible Preferred Stock may not transfer the certificate(s) representing
such shares of Series A Convertible Preferred Stock unless such holder first
physically surrenders such certificate(s) to the Corporation, whereupon the
Corporation will forthwith issue and deliver upon the order of such holder of
shares of Series A Convertible Preferred Stock new certificate(s) of like tenor,
registered as such holder of shares of Series A Convertible Preferred Stock
(upon payment by such holder of shares of Series A Convertible Preferred Stock
of any applicable transfer taxes) may request, representing in the aggregate the
remaining number of shares of Series A Convertible Preferred Stock represented
by such certificate(s). Each holder of shares of Series A Convertible Preferred
Stock, by acceptance of a certificate for such shares, acknowledges and agrees
that (1) by reason of the provisions of this paragraph, following conversion of
any shares of Series A Convertible Preferred Stock represented by such
certificate, the number of shares of Series A Convertible Preferred Stock
represented by such certificate may be less than the number of shares stated on
such certificate, and (2) the Corporation may place a legend on the certificates
for shares of Series A Convertible Preferred Stock which refers to or describes
the provisions of this paragraph.

                  (B) The Corporation shall pay any transfer tax arising in
connection with any conversion of shares of Series A Convertible Preferred Stock
except that the Corporation shall not, however, be required to pay any tax which
may be payable in respect of any transfer involved in the issue and delivery
upon conversion of shares of Common Stock or other securities or property in a
name other than that of the holder of the shares of the Series A Convertible
Preferred Stock being converted, and the Corporation shall not be required to
issue or deliver any such shares or other securities or property unless and
until the person or persons requesting the issuance thereof shall have paid to
the Corporation the amount of any such tax or shall have established to the
satisfaction of the Corporation that such tax has been paid. The number of
shares of Common Stock to be issued upon each conversion of shares of Series A
Convertible Preferred Stock shall be the number set forth in the applicable
Conversion Notice which number shall be conclusive absent manifest error. The
Corporation shall notify a holder who has given a Conversion Notice of any claim
of manifest error within one Trading Day after such holder gives such Conversion
Notice and no such claim of error shall limit or delay performance of the
Corporation's obligation to issue upon such conversion the number of shares of
Common Stock which are not in dispute. A Conversion Notice shall be deemed for
all purposes to be in proper form unless the Corporation notifies a holder of
shares of Series A Convertible Preferred Stock being converted within one
Trading Day after a Conversion Notice has been given (which notice shall specify
all defects in the Conversion Notice) and any

                                      -26-
<PAGE>   27
Conversion Notice containing any such defect shall nonetheless be effective on
the date given if the converting holder promptly corrects all such defects.

                  (4)      The Corporation (and any successor corporation) shall
take all action necessary so that a number of shares of the authorized but
unissued Common Stock (or common stock in the case of any successor corporation)
sufficient to provide for the conversion of the Series A Convertible Preferred
Stock outstanding upon the basis hereinbefore provided are at all times reserved
by the Corporation (or any successor corporation), free from preemptive rights,
for such conversion, subject to the provisions of the next succeeding paragraph.
If the Corporation shall issue any securities or make any change in its capital
structure which would change the number of shares of Common Stock into which
each share of the Series A Convertible Preferred Stock shall be convertible as
herein provided, the Corporation shall at the same time also make proper
provision so that thereafter there shall be a sufficient number of shares of
Common Stock authorized and reserved, free from preemptive rights, for
conversion of the outstanding Series A Convertible Preferred Stock on the new
basis. If at any time the number of authorized but unissued shares of Common
Stock shall not be sufficient to effect the conversion of all of the outstanding
shares of Series A Convertible Preferred Stock, the Corporation promptly shall
seek, and use its best efforts to obtain and complete, such corporate action as
may, in the opinion of its counsel, be necessary to increase its authorized but
unissued shares of Common Stock to such number of shares as shall be sufficient
for such purpose.

                  (5)      In case any Reorganization Event shall be effected in
such a way that holders of Common Stock shall be entitled to receive stock,
securities or assets (including cash) with respect to or in exchange for shares
of the Common Stock, then, prior to and as a condition of such Reorganization
Event, lawful and adequate provision shall be made whereby the holders of Series
A Convertible Preferred Stock shall thereafter have the right to receive upon
conversion of the Series A Convertible Preferred Stock and in lieu of the shares
of Common Stock immediately theretofore issuable upon conversion of the Series A
Convertible Preferred Stock, such shares of stock, securities or assets
(including cash) as may be issued or payable with respect to or in exchange for
a number of outstanding shares of Common Stock equal to the number of shares of
Common Stock immediately theretofore issuable upon conversion of the Series A
Convertible Preferred Stock had such Reorganization Event not taken place. In
any such case, appropriate provision shall be made with respect to the rights
and interests of the holders of Series A Convertible Preferred Stock to the end
that the provisions hereof (including, without limitation, provisions for
adjustment of the Conversion Price and the number of shares of Common Stock
issuable upon conversion of the Series A Convertible Preferred Stock) shall
thereafter be applicable, as nearly as may be, in relation to any stock,
securities or assets thereafter deliverable upon the conversion of the Series A
Convertible Preferred Stock. The Corporation shall not effect any such
Reorganization Event (i) unless prior to or simultaneously with the consummation
thereof the survivor or successor corporation (if other than the Corporation)
resulting from such Reorganization Event or the corporation or other entity
purchasing such assets shall assume by written instrument executed and sent to
each holder of Series A Convertible Preferred Stock, the obligation to deliver
to such holder of Series A Convertible Preferred Stock such shares of stock,
securities or assets as, in accordance with the foregoing provisions, such
holder of Series A Convertible Preferred Stock may be entitled to receive, and
containing the express assumption by such successor corporation or other entity
of

                                      -27-
<PAGE>   28
the due and punctual performance and observance of every provision herein to be
performed and observed by the Corporation and of all liabilities and obligations
of the Corporation hereunder, and (ii) in which the Corporation, as opposed to
another party to the Reorganization Event, shall be required under any
circumstances to make a cash payment at any time to the holders of the Series A
Convertible Preferred Stock; provided, however, that this clause (5) shall not
limit the Corporation's obligation to make cash payments pursuant to Section 7
or Section 11 if the Corporation fails to give a Control Notice in accordance
with the terms thereof.

                  (6)      If a holder shall have given a Conversion Notice for
shares of Series A Convertible Preferred Stock, the Corporation shall issue and
deliver to such person certificates for the Common Stock issuable upon such
conversion within three Trading Days after such Conversion Notice is given and
the person converting shall be deemed to be the holder of record of the Common
Stock issuable upon such conversion, and all rights with respect to the shares
surrendered shall forthwith terminate except the right to receive the Common
Stock or other securities, cash, or other assets as herein provided. If a holder
shall have given a Conversion Notice as provided herein, the Corporation's
obligation to issue and deliver the certificates for Common Stock shall be
absolute and unconditional, irrespective of any action or inaction by the
converting holder to enforce the same, any waiver or consent with respect to any
provision thereof, the recovery of any judgment against any person or any action
to enforce the same, any failure or delay in the enforcement of any other
obligation of the Corporation to such holder, or any setoff, counterclaim,
recoupment, limitation or termination, or any breach or alleged breach by such
holder or any other person of any obligation to the Corporation or any violation
or alleged violation of law by such holder or any other person, and irrespective
of any other circumstance which might otherwise limit such obligation of the
Corporation to the holder in connection with such conversion. If the Corporation
fails to issue and deliver the certificates for the Common Stock to the holder
converting shares of Series A Convertible Preferred Stock pursuant to the first
sentence of this paragraph within three Trading Days after such Conversion
Notice is given, in addition to any other liabilities the Corporation may have
hereunder and under applicable law (1) the Corporation shall pay or reimburse
such holder on demand for all out-of-pocket expenses including, without
limitation, reasonable fees and expenses of legal counsel incurred by such
holder as a result of such failure, (2) for each Trading Day thereafter on which
the Corporation so fails to deliver such certificates, the Conversion Price
applicable to such conversion shall be reduced by an amount equal to one percent
of the amount that the Conversion Price would otherwise be, and (3) such holder
may by written notice (which may be given by mail, courier, personal service or
telephone line facsimile transmission) or oral notice (promptly confirmed in
writing) given at any time prior to delivery to such holder of the certificates
for the shares of Common Stock issuable upon such conversion of shares of Series
A Convertible Preferred Stock, rescind such conversion, whereupon such holder
shall have the right to convert such shares of Series A Convertible Preferred
Stock thereafter in accordance herewith.

                  (7)      No fractional shares of Common Stock shall be issued
upon conversion of Series A Convertible Preferred Stock but, in lieu of any
fraction of a share of Common Stock to purchase fractional shares of Common
Stock which would otherwise be issuable in respect of the aggregate number of
such shares surrendered for conversion at one time by the same holder, the
Corporation shall pay in cash an amount equal to the product of (i) the
arithmetic average of the

                                      -28-
<PAGE>   29
Market Price of one share of Common Stock on the three consecutive Trading Days
ending on the Trading Day immediately preceding the Conversion Date times (ii)
such fraction of a share.

                  (8)      The Conversion Amount shall be adjusted from time to
time under certain circumstances, subject to the provisions of Section 10(b)(1),
as follows:

                  (i)      In case the Corporation shall issue rights or
warrants on a pro rata basis to all holders of the Common Stock entitling such
holders to subscribe for or purchase Common Stock on the record date referred to
below at a price per share less than the Current Price for such record date,
then in each such case the Conversion Amount in effect on such record date shall
be adjusted in accordance with the following formula:

         C(1) = C x   O + N
                      -----
                    O + N x P
                      -----
                        M

where

         C(1)  = the adjusted Conversion Amount

         C     = the current Conversion Amount

         O     = the number of shares of Common Stock outstanding on the
                 record date.

         N     = the number of additional shares of Common Stock issuable
                 pursuant to the exercise of such rights or warrants.

         P     = the offering price per share of the additional shares (which
                 amount shall include amounts received by the Corporation in
                 respect of the issuance and the exercise of such rights or
                 warrants).

         M     = the Current Price per share of Common Stock on the record
                 date.

Such adjustment shall become effective immediately after the record date for the
determination of stockholders entitled to receive such rights or warrants. If
any or all such rights or warrants are not so issued or expire or terminate
before being exercised, the Conversion Amount then in effect shall be readjusted
appropriately.

                  (ii)     In case the Corporation shall, by dividend or
otherwise, distribute to all holders of its Junior Stock (as hereinafter
defined) evidences of its indebtedness or assets (including securities, but
excluding any warrants or subscription rights referred to in subparagraph (i)
above and any dividend or distribution paid in cash out of the retained earnings
of the Corporation), then in each such case the Conversion Amount then in effect
shall be adjusted in accordance with the formula

                                      -29-
<PAGE>   30
         C(1) = C x    M
                      ---
                     M - F

where

         C(1)  = the adjusted Conversion Amount

         C     = the current Conversion Amount

         M     = the Current Price per share of Common Stock on the record
                 date mentioned below.

         F     = the aggregate amount of such cash dividend and/or the fair
                 market value on the record date of the assets or securities to
                 be distributed divided by the number of shares of Common Stock
                 outstanding on the record date. The Board of Directors shall
                 determine such fair market value, which determination shall be
                 conclusive.

Such adjustment shall become effective immediately after the record date for the
determination of stockholders entitled to receive such dividend or distribution.
For purposes of this subparagraph (ii), "Junior Stock" shall include any class
of capital stock ranking junior as to dividends or upon liquidation to the
Series A Convertible Preferred Stock.

                  (iii)    All calculations hereunder shall be made to the
nearest cent or to the nearest 1/100 of a share, as the case may be.

                  (iv)     If at any time as a result of an adjustment made
pursuant to Section 10(b)(5), the holder of any Series A Convertible Preferred
Stock thereafter surrendered for conversion shall become entitled to receive
securities, cash, or assets other than Common Stock, the number or amount of
such securities or property so receivable upon conversion shall be subject to
adjustment from time to time in a manner and on terms nearly equivalent as
practicable to the provisions with respect to the Common Stock contained in
subparagraphs (i) to (iii) above.

                  (9)      Except as otherwise provided above in this Section
10, no adjustment in the Conversion Amount shall be made in respect of any
conversion for share distributions or dividends theretofore declared and paid or
payable on the Common Stock.

                  (10)     Whenever the Conversion Amount is adjusted as herein
provided, the Corporation shall send to each holder and each transfer agent, if
any, for the Series A Convertible Preferred Stock and the transfer agent for the
Common Stock, a statement signed by the Chairman of the Board, the President, or
any Vice President of the Corporation and by its Treasurer or its Secretary or
an Assistant Secretary stating the adjusted Conversion Amount determined as
provided in this Section 10, and any adjustment so evidenced, given in good
faith, shall be binding upon all stockholders and upon the Corporation. Whenever
the Conversion Amount is adjusted, the Corporation will give notice by mail to
the holders of record of Series A Convertible Preferred Stock, which notice
shall be made within 15 days after the effective date of such adjustment and
shall state the adjustment and the Conversion Amount. Notwithstanding

                                      -30-
<PAGE>   31
the foregoing notice provisions, failure by the Corporation to give such notice
or a defect in such notice shall not affect the binding nature of such corporate
action of the Corporation.

                  (11)     In case on or after the Issuance Date:

                  (A)      the Corporation shall declare a dividend (or any
other distribution) on the Common Stock (other than in cash out of retained
earnings); or

                  (B)      the Corporation shall authorize the granting to the
holders of the Common Stock of rights or warrants to subscribe for or purchase
any share of any class or any other rights or warrants; or

                  (C)      the Board of Directors shall authorize any
reclassification of the Common Stock (other than a subdivision or combination of
the outstanding Common Stock, or a change in par value, or from par value to no
par value, or from no par value to par value), or any consolidation or merger or
other business combination transaction to which the Corporation is a party and
for which approval of any stockholders of the Corporation is required, or the
sale or transfer of all or substantially all of the assets of the Corporation;
or

                  (D)      there shall be pending the voluntary or involuntary
dissolution, liquidation or winding-up of the Corporation;

the Corporation shall give the holders of record of the Series A Convertible
Preferred Stock, as promptly as possible but in any event at least ten Trading
Days prior to the applicable date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution or rights or warrants, or, if a record is not to be taken, the date
as of which the holders of Common Stock of record to be entitled to such
dividend, distribution or rights are to be determined, or (y) the date on which
such reclassification, consolidation, merger, other business combination
transaction, sale, transfer, dissolution, liquidation or winding-up is expected
to become effective or occur, and the date as of which it is expected that
holders of Common Stock of record who shall be entitled to exchange their Common
Stock for securities or other property deliverable upon such reclassification,
consolidation, merger, other business combination transaction, sale, transfer,
dissolution, liquidation or winding-up shall be determined. Such notice shall
not include any information which would be material non-public information for
purposes of the 1934 Act. Failure to give such notice, or any defect therein,
shall not affect the legality or validity of such dividend, distribution,
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding-up. In the case of any such action of which the
Corporation gives such notice to the holders of record of the Series A
Convertible Preferred Stock or is required to give such notice to such holders,
such holders shall be entitled to give a Conversion Notice which is contingent
on the completion of such action.

                  SECTION 11.       REDEMPTION AT OPTION OF HOLDERS.

                  (a)      REDEMPTION RIGHT. Subject to Section 11(b)(4), if an
Optional Redemption Event occurs, then, in addition to any other right or remedy
of any holder of shares of Series A Convertible Preferred Stock, each holder of
shares of Series A Convertible Preferred Stock shall have the right, at such
holder's option, to require the Corporation to redeem all of

                                      -31-
<PAGE>   32
such holder's shares of Series A Convertible Preferred Stock, or any portion
thereof, on the date that is 15 Business Days after the date such holder gives
the Corporation an Optional Redemption Notice with respect to such Optional
Redemption Event at any time while any of such holder's shares of Series A
Convertible Preferred Stock are outstanding, at a price equal to the Optional
Redemption Price.

                  (b)      NOTICES; METHOD OF EXERCISING OPTIONAL REDEMPTION
RIGHTS, ETC. (1) On or before the fifth Business Day after the occurrence of an
Optional Redemption Event, the Corporation shall give to each holder of
outstanding shares of Series A Convertible Preferred Stock a notice of the
occurrence of such Optional Redemption Event and of the redemption right set
forth herein arising as a result thereof. Such notice from the Corporation shall
set forth:

                  (i)      the date by which the optional redemption right
         must be exercised, and

                  (ii)     a description of the procedure (set forth below)
which each such holder must follow to exercise such holder's optional redemption
right.

No failure of the Corporation to give such notice or defect therein shall limit
the right of any holder of shares of Series A Convertible Preferred Stock to
exercise the optional redemption right or affect the validity of the proceedings
for the redemption of such holder's shares of Series A Convertible Preferred
Stock.

                  (2)      To exercise its optional redemption right, each
holder of outstanding shares of Series A Convertible Preferred Stock shall
deliver to the Corporation on or before the 30th day after the notice required
by Section 11(b)(1) is given to such holder (or if no such notice has been given
by the Corporation to such holder, within 40 days after such holder first learns
of such Optional Redemption Event) an Optional Redemption Notice to the
Corporation. At the Corporation's option, an Optional Redemption Notice may be
revoked by such holder giving such Optional Redemption Notice by giving notice
of such revocation to the Corporation at any time prior to the time the
Corporation pays the Optional Redemption Price to such holder.

                  (3)      If a holder of shares of Series A Convertible
Preferred Stock shall have given an Optional Redemption Notice, on the date
which is 15 Business Days after the date such Optional Redemption Notice is
given (or such later date as such holder surrenders such holder's certificates
for the shares of Series A Convertible Preferred Stock to be redeemed) the
Corporation shall make payment in immediately available funds of the applicable
Optional Redemption Price to such account as specified by such holder in writing
to the Corporation at least one Business Day prior to the applicable redemption
date.

                  (4)      Notwithstanding any other provision of this
Certificate of Designations, if an Optional Redemption Event occurs by reason of
events which are not solely within the control of the Corporation, the
Corporation shall have the right to give a Control Notice to the holders of
shares of Series A Convertible Preferred Stock at any time after such Optional
Redemption Event occurs and prior to the earlier of (1) the date on which all
holders of shares of Series A Convertible Preferred Stock who had the right
(other than as limited by this Section 11(b)(4)) to require redemption of any
shares of Series A Convertible Preferred Stock by reason of the

                                      -32-
<PAGE>   33
occurrence of such Optional Redemption Event no longer have such right and (2)
the applicable Optional Redemption Date by reason of the earliest Optional
Redemption Notice given by any holder of shares of Series A Convertible
Preferred Stock by reason of such Optional Redemption Event. If the Corporation
timely gives such Control Notice to the holders of shares of Series A
Convertible Preferred Stock, then in lieu of payment of the Optional Redemption
Price by reason of any such Optional Redemption Event and commencing on the
first date on which such Optional Redemption Event occurs the following
adjustments shall take effect (subject to the provisions of Section 7(a)(5)(B)):

                  (A)      In the case of an Optional Redemption Event described
         in clauses (1), (2), (3), (4) or (6) of the definition of the term
         Optional Redemption Event, for so long as such Optional Redemption
         Event continues and for a period of ten Trading Days thereafter the
         Conversion Price will be 70% of the amount which the Conversion Price
         would otherwise be; and

                  (B)      In the case of an Optional Redemption Event described
         in clause (5) of the definition of the term Optional Redemption Event,
         for so long as any shares of Preferred Stock are outstanding the
         Conversion Price will be 70% of the amount which the Conversion Price
         would otherwise be.

For purposes of this Section 11(b)(4), an Optional Redemption Event shall be
deemed to have occurred by reason of events which are not solely within the
control of the Corporation if a requirement of the Corporation to redeem, or a
right of any holder of shares of Series A Convertible Preferred Stock to require
redemption of, shares of Series A Convertible Preferred Stock by reason thereof
would result in the Corporation being required to classify the Series A
Convertible Preferred Stock as redeemable preferred stock on a balance sheet of
the Corporation prepared in accordance with Generally Accepted Accounting
Principles and Regulation S-X of the SEC, and, in the case of an Optional
Redemption Event described in clause (5) of the definition of the term Optional
Redemption Event, the Board does not have the right to approve or disapprove the
transactions resulting in such event. If as a result of any of the adjustments
to the Conversion Price required by this Section 11(b)(4) the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all of the outstanding shares of Series A Convertible
Preferred Stock, such insufficiency shall be deemed to be covered by the
applicable Control Notice and the Corporation shall have no obligation to redeem
any shares of Series A Convertible Preferred Stock by reason thereof. The
Corporation thereupon will use its best efforts to increase the authorized
number of shares of Common Stock in accordance with Section 10(b)(4).

                  (C)      OTHER. (1) In connection with a redemption pursuant
to this Section 11 of less than all of the shares of Series A Convertible
Preferred Stock evidenced by a particular certificate, promptly, but in no event
later than three Business Days after surrender of such certificate to the
Corporation, the Corporation shall issue and deliver to such holder a
replacement certificate for the shares of Series A Convertible Preferred Stock
evidenced by such certificate which have not been redeemed.

                  (2) An Optional Redemption Notice given by a holder of shares
of Series A Convertible Preferred Stock shall be deemed for all purposes to be
in proper form unless the Corporation notifies such holder in writing within
three Business Days after such Optional Redemption Notice has been given (which
notice shall specify all defects in such Optional Redemption Notice), and any
Optional Redemption Notice containing any such defect shall nonetheless be
effective on the date given if such holder promptly undertakes to correct all
such defects. No such claim of error shall limit or delay performance of the
Corporation's obligation to redeem all shares of Series A Convertible Preferred
Stock not in dispute whether or not such holder makes such undertaking.

                  SECTION 12.       VOTING RIGHTS; CERTAIN RESTRICTIONS.

Incorporation if the amendment, alteration, or repeal materially and adversely
affects the powers, preferences, or special rights of the Series A Convertible
Preferred Stock, or (2) the creation and issuance of any Senior Dividend Stock
or Senior Liquidation Stock; provided, however, that any increase in the
authorized Preferred Stock of the Corporation or the creation and issuance of
any stock which is both Junior Dividend Stock and Junior Liquidation Stock shall
not be deemed to affect materially and adversely such powers, preferences, or
special rights and any such increase or creation and issuance may be made
without any such vote by the holders of Series A Convertible Preferred Stock
except as otherwise required by law.

                  (c)      REPURCHASES OF SERIES A CONVERTIBLE PREFERRED STOCK.
The Corporation shall not repurchase or otherwise acquire any shares of Series A
Convertible Preferred Stock (other than pursuant to Sections 7(a), 9(a), 9(b) or
11) unless the Corporation offers to repurchase or otherwise acquire
simultaneously a pro rata portion of each holder's shares of Series A
Convertible Preferred Stock for cash at the same price per share.

                  (d)      OTHER.  So long as any shares of Series A
Convertible Preferred Stock are outstanding:

                  (1)      PAYMENT OF OBLIGATIONS. The Corporation will pay and

adequate for the conduct of their businesses and the value of their properties.

                  (3)      CONDUCT OF BUSINESS AND MAINTENANCE OF EXISTENCE. The
Corporation will continue, and will cause each subsidiary of the Corporation to
continue, to engage in business of the same general type as conducted by the

whole.

                  (5)      INVESTMENT COMPANY ACT. The Corporation will not be
