                                   AGREEMENT

This agreement dated September 6, 2000 between Norman R. "Chip" Harpster, Jr.
(Executive) and Millennium Cell Inc. (Company). The following are the terms of
this agreement.

1.  Title - The Executive shall be the Vice President, Finance and
    Administration & Chief Financial Officer of the Company reporting directly
    to the President and Chief Executive Officer.

2.  Base Salary - Base salary shall be at $200,000 (payable on a semi-monthly
    basis) per annum, beginning October 9, 2000. The Executive will be eligible
    for salary adjustments as approved by the Compensation Committee of the
    Board of Directors.

3.  Bonus - The Executive will be eligible for a target bonus of 50% of base
    salary. Executive will be eligible for bonus adjustments as approved by the
    Compensation Committee of the Board of Directors.

4.  Equity/Stock Options - Upon joining the company, the Executive shall
    receive 212,500 stock options at a strike price of $2.90/share. The Options
    will have a term of a minimum of 5 years and a maximum of 10 years. The
    exact term shall be determined by the Company and shall apply to all other
    employees as well according to the Omnibus Stock Option Plan to be
    approved by the Board of Directors. In addition, the Company anticipates
    that the Executive would be a participant in future options granted by this
    Plan.

    The Vesting Schedule of the 212,500 stock options is based on the
    anniversary date of the Executive's first day of employment, October 9,
    2000, in accordance with the following schedule:

    Year 1 - 1/3 (33.33%)
    Year 2 - 1/3 (33.33%)
    Year 3 - 1/3 (33.34%)

5.  Termination - If the Executive is terminated by the Company other than for
    "Cause" (Cause is defined as fraud, embezzlement, or conviction of a crime
    involving moral turpitude), then the Executive's Options shall vest in
    accordance with the terms of the Company's Stock Option Plan.

    There shall be Severance of one times the then base salary plus one year
    bonus (bonus of greater of 50% of then base salary or the actual bonus paid
    for the full year preceding the year of termination. The severance shall be
    paid in four (4) quarterly/equal increments with no duty to mitigate; nor
    shall this be a right of set-off.

    In the event of a "Change of Control," (40% or more in the change of stock
    ownership in the company or the sale of substantially all of the company's
    assets), all stock options and other equity will vest immediately and the
    Executive shall be entitled to the Severance stated above.

6.  Tax Gross-Up - The Executive shall be grossed-up for any excise taxes under
    Section 280(g) - Parachute Payments of any successor provision. The intent
    of this gross-up is to put the Executive in the same after tax position as
    if the excise tax was not imposed. The Company's accounting firm shall
    compute the Excise Tax. If the Company's accountant's determination of the
    Excise Taxes turns out to be inconsistent with the IRS, then the Executive
    shall notify the Company on the IRS's position. The Company shall defend
    its position and increase the gross-up amount to the extent the IRS
    prevails in its position; plus reimburse the Executive for any interest
    and penalties associated with the accountant's computations.

7.  Death or Disability - All the Executive's Stock Options shall vest
    immediately in the event of death or disability and the Executive or his
    personal representative shall have 12 months from termination of employment
    to exercise his Stock Options. Disability shall be determined by an
    independent physician selected jointly by the Company and the Executive's
    personal representative, to determine that by reason of mental or physical
    illness the Executive would be able to resume his duties in the
    foreseeable future.

8.  Non-Compete/Non-Solicition - During the employment and for a period of 12
    months following termination of employment, the Executive is not permitted
    to engage directly or indirectly in any business that generates hydrogen
    energy for the use in conventional engines, fuel cells, or batteries; nor
    shall the Executive for the same period, directly or indirectly endeavor
    to entice away any employees of the Company.

EXHIBIT 4.4

                      CERTIFICATE OF DESIGNATION OF SERIES
                   AND DETERMINATION OF RIGHTS AND PREFERENCES

                                       OF

                            SERIES A PREFERRED STOCK

                                       OF

                               CROSSWALK.COM, INC.

       CROSSWALK.COM, INC., a Delaware corporation (the "Company"), acting
pursuant to Section 151 of the General Corporation Law of Delaware, does hereby
submit the following Certificate of Designation of Series and Determination of
Rights and Preferences of its Series A Preferred Stock.

       FIRST: The name of the Company is Crosswalk.com, Inc.

       SECOND: By unanimous consent of the Board of Directors (the "Board") of
the Company dated September 19, 2000, the following resolutions were duly
adopted:

       WHEREAS the Amended and Restated Certificate of Incorporation of the
Company (the "Certificate of Incorporation") authorizes 5,000,000 shares of
preferred stock, par value $.001 per share ("Preferred Stock"), issuable from
time to time in one or more series;

       WHEREAS the Board of the Company is authorized, subject to limitations
prescribed by law and by the provisions of paragraph four (4) of the Company's
Certificate of Incorporation, to establish and fix the number of shares to be
included in any series of Preferred Stock and the designation, rights,
preferences, powers, restrictions and limitations of the shares of such series;
and

       WHEREAS it is the desire of the Board to establish and fix the number of
shares to be included in a new series of Preferred Stock and the designation,
rights, preferences and limitations of the shares of such new series.

       NOW, THEREFORE, BE IT RESOLVED that pursuant to paragraph four of the
Company's Certificate of Incorporation, there is hereby established a new series
of Preferred Stock, and that the Board does hereby fix and determine the
designation, rights, preferences, powers, restrictions and limitations set forth
as follows:

SECTION 1.    DESIGNATION; RANK.

       This series of cumulative convertible Preferred Stock shall be designated
and known as the "Series A Preferred Stock." The number of shares constituting
the Series A Preferred Stock shall be 80,000 shares. The Series A Preferred
Stock shall, with respect to dividends and rights upon liquidation, dissolution
or winding up, whether voluntary or involuntary, rank prior to the common stock
of the Company, par value $.01 per share (the "Common Stock").

<PAGE>   2

SECTION 2.    DIVIDENDS.

       The holders of outstanding shares of Series A Preferred Stock shall be
entitled to receive a dividend of 6% per annum, payable, at the election of the
Board, out of funds legally available for such purpose or in shares of Common
Stock, in preference and priority to any payment of any dividend on Common
Stock. If the dividend is to be paid in Common Stock, the number of shares shall
be determined by dividing the dividend payable by the average closing price of
the Company's Common Stock for the sixty (60) trading days prior to the dividend
declaration or redemption of the Series A Preferred Stock. Such dividends shall
be payable only when, as and if declared by the Board, and such dividends shall
accrue and be cumulative.

SECTION 3.    LIQUIDATION PREFERENCE.

       (a) Upon any liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary, before any distribution or payment shall be
made to the holders of any Common Stock, the holders of Series A Preferred Stock
shall be entitled to be paid out of the remaining assets of the Company legally
available for distribution with respect to each share of Series A Preferred
Stock an amount equal to the sum of (i) $25 per share, as adjusted for any stock
dividends, combinations or splits with respect to such shares (the "Original
Series A Issue Price") plus (ii) any declared but unpaid dividends thereon (such
sum, the "Series A Liquidation Value"). If upon any such liquidation,
dissolution or winding up of the Company the remaining assets of the Company
available for distribution to its stockholders shall be insufficient to pay the
holders of shares of Series A Preferred Stock the full Series A Liquidation
Value, the holders of shares of Series A Preferred Stock shall share ratably in
any distribution of the remaining assets of the Company in proportion to the
respective amounts which would otherwise be payable in respect of the shares
held by them upon such distribution if all amounts payable on or with respect to
such shares were paid in full.

       (b) After payment in full of the Series A Liquidation Value, the
remaining assets of the Company legally available for distribution, if any,
shall be distributed to the holders of Common Stock.

       (c) The following events shall be considered a liquidation for purposes
of Section 3(a) above and Section 6(a) below unless the holders of at least a
majority of the voting power of all then outstanding shares of Series A
Preferred Stock, voting together as a single class, vote otherwise:

       (i)    any merger, consolidation or other business combination of the
              Company in which the stockholders of the Company immediately prior
              to such transaction will, immediately after such transaction (by
              virtue of securities issued in the transaction or otherwise),
              beneficially own (as determined pursuant to rule 13d-3 under the
              Securities Exchange Act of 1934, as amended (the "Exchange Act")
              capital stock representing less than fifty percent (50%) of the
              voting power of the surviving entity's voting stock immediately
              after such transaction (an "Acquisition"); or

       (ii)   a sale of all or substantially all of the assets of the Company to
              any other entity, where the Company's stockholders immediately
              prior to such sale will, immediately after such sale (by virtue of
              securities issued as consideration for the Company's sale or
              otherwise), beneficially own (as determined pursuant to Rule 13d-3
              under the Exchange Act) capital stock representing less than fifty
              percent (50%) of the voting power of the acquiring entity's voting
              stock (an "Asset Transfer").

       (d) In either of the events in Section 3(c) above, if the consideration
received by the Company is other than cash, its value will be deemed its fair
market value as determined in good faith by the Board. Any securities shall be
valued as follows:

              (i)    Securities not subject to investment letter or other
                     similar restrictions on free marketability covered by (ii)
                     below:

                     (A) If traded on a securities exchange or through the
                            Nasdaq National Market, the value shall be deemed to
                            be the average of the closing prices of the
                            securities on such quotation system over the thirty
                            (30) day period ending three (3) days prior to the
                            closing;

                     (B) If actively traded over-the-counter, the value shall be
                            deemed to be the average of the closing bid or sale
                            prices (whichever is applicable) over the thirty
                            (30) day period ending three (3) days prior to the
                            closing; and

                     (C) If there is no active public market, the value shall be
                            the fair market value thereof, as mutually
                            determined by the Board and the holders of at least
                            a majority of the voting power of all then
                            outstanding shares of Series A Preferred Stock.

              (ii)   The method of valuation of securities subject to investment
                     letter or other restrictions on free marketability (other
                     than restrictions arising solely by virtue of a
                     stockholder's status as an affiliate or former affiliate)
                     shall be to make an appropriate discount from the market
                     value determined as above in (i)(A),(B) or (C) to reflect
                     the approximate fair market value thereof, as mutually
                     determined by the Board and the holders of at least a
                     majority of the voting power of all then outstanding shares
                     of Series A Preferred Stock.

SECTION 4.    VOTING RIGHTS.

       (a)    Each holder of outstanding shares of Series A Preferred Stock
shall be entitled to the number of votes equal to the number of whole shares of
Common Stock into which all of the shares of Series A Preferred Stock held by
such holder are convertible (as adjusted from time to time pursuant to Section 6
hereof), at each meeting of stockholders of the Company (and written actions of
stockholders in lieu of meetings) with respect to any and all matters presented
to the stockholders of the Company for their action or consideration. Except as
provided by law, by the express provisions hereof, or by the provisions
establishing any other series of Preferred Stock, holders of Series A Preferred
Stock and of any outstanding series of Other Preferred Stock shall vote together
with the holders of Common Stock as a single class.

       (b)    On the date this Certificate of Designations is filed with the
State of Delaware, the holders of the Series A Preferred Stock will nominate
Rusty Lewis, Jon Morgan and Eric Oliver as Director to the Corporation's Board
of Directors (the "Series A Board Nominees"). The Corporation's Board of
Directors will appoint one of the three Series A Board Nominees to serve as a
Director of the Corporation (the "Series A Director") until the next annual
meeting of the shareholders. Following the next annual meeting (and each
subsequent annual meeting) of the Corporation, the Series A Director will
continue to serve as a Director as long as the Series A Director is elected (and
reelected) by all the holders of the Series A Preferred Stock and Common Stock
voting together as a single class.

SECTION 5.    COVENANTS.

              (a)    In addition to any other rights provided by law, the
                     Corporation shall not, without first obtaining the
                     affirmative vote or written consent of the holders of at
                     least fifty percent (50%) of the outstanding shares of the
                     Series A Preferred Stock (i) authorize or create (by
                     reclassification or otherwise) any new class or series of
                     shares of capital stock with rights senior or equal to the
                     Series A Preferred Stock; (ii) amend or waive any provision
                     of this Corporation's Certificate of Incorporation or
                     Bylaws in any manner that adversely affects the
                     preferences, privileges or rights of the Series A; (iii)
                     redeem or repurchase Common Stock or any other junior
                     equity security, except for shares repurchased upon the
                     termination of an employee, officer, director or consultant
                     pursuant to a restricted stock purchase agreement; (iv) pay
                     or declare any dividend on the Common Stock or any other
                     junior equity security other than a dividend in Common
                     Stock; or (v) liquidate or wind up the Corporation.

       The Corporation shall not take any action, which results in any merger,
corporate reorganization, sale of control, or any transaction in which all or
substantially all of the assets of the Corporation are sold, unless the Series A
Director votes in favor of such action.

SECTION 6.    CONVERSION RIGHTS.

       The holders of the Series A Preferred Stock shall have conversion rights
as follows (the "Conversion Rights"):

       (a)    Right to Convert. Each share of Series A Preferred Stock shall be
convertible, at the option of the holder thereof, at any time and from time to
time, into such number of fully paid and nonassessable shares of Common Stock as
is determined by dividing the Original Series A Issue Price by the Conversion
Price (as defined below) in effect at the time of conversion. The Conversion
Price at which shares of Common Stock shall be deliverable upon conversion of
Series A Preferred Stock without the payment of additional consideration by the
holder thereof (the "Conversion Price") shall initially be $2.32. Such initial
Conversion Price and the rate at which shares of Series A Preferred Stock may be
converted into shares of Common Stock, shall be subject to adjustment as
provided below.

       (b)    Fractional Shares. No fractional shares of Common Stock shall be
issued upon conversion of the Series A Preferred Stock. In lieu of fractional
shares, the Company shall round such fraction to the nearest whole number.

       (c)    Mechanics of Conversion.

              (i)    In order to convert shares of Series A Preferred Stock into
                     shares of Common Stock, the holder shall surrender the
                     certificate or certificates for such shares of Series A
                     Preferred Stock at the office of the transfer agent (or at
                     the principal office of the Company if the Company serves
                     as its own transfer agent), together with written notice
                     that such holder elects to convert all or any number of the
                     shares represented by such certificate or certificates.
                     Such notice shall state the number of shares of Series A
                     Preferred Stock, which the holder seeks to convert. If
                     required by the Company, certificates surrendered for
                     conversion shall be endorsed or accompanied by a written
                     instrument or instruments of transfer, in form satisfactory
                     to the Company, duly executed by the registered holder or
                     his or its attorney duly authorized in writing. The date of
                     receipt of such certificates and notice by the transfer
                     agent or the Company shall be the conversion date
                     ("Conversion Date"). As soon as practicable after the
                     Conversion Date, the Company shall promptly issue and
                     deliver at such office to such holder a certificate or
                     certificates for the number of shares of Common Stock to
                     which such holder is entitled. Such conversion shall be
                     deemed to have been made at the close of business on the
                     date of such surrender of the certificate representing the
                     shares of Series A Preferred Stock to be converted, and the
                     person entitled to receive the shares of Common Stock
                     issuable upon such conversion shall be treated for all
                     purposes as the record holder of such shares of Common
                     Stock on such date.

              (ii)   The Company shall at all times during which the Series A
                     Preferred Stock shall be outstanding, reserve and keep
                     available out of its authorized but unissued stock, for the
                     purpose of effecting the conversion of the Series A
                     Preferred Stock, such number of its duly authorized shares
                     of Common Stock as shall from time to time be sufficient to
                     effect the conversion of all outstanding Series A Preferred
                     Stock. Before taking any action which would cause an
                     adjustment reducing the Conversion Price below the then par
                     value of the shares of Common Stock issuable upon
                     conversion of the Series A Preferred Stock, the Company
                     will take any corporate action which may, in the opinion of
                     its counsel, be necessary in order that the Company may
                     validly and legally issue fully paid and nonassessable
                     shares of Common Stock at such adjusted Conversion Price.

              (iii)  Upon any conversion, the Company shall promptly pay in cash
                     or Common Stock (at the Common Stock's fair market value
                     determined by the Board as of the date of such conversion)
                     or a combination of cash and Common Stock, any declared but
                     unpaid dividends on the shares of Series A Preferred Stock
                     being converted.

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

       (d)    Adjustments to Conversion Price for Diluting Issues.

              (i)    Special Definitions. For purposes of this Subsection 6(b),
                     the following definitions shall apply:

                            options granted to employees, vendors, officers,

                            the first share of Series A Preferred Stock is first
                            issued.

                     (C)   "Convertible Securities" shall mean any evidences of

                            Common Stock.

                     (D)   "Additional Shares of Common Stock" shall mean all

                            (2)    by reason of a dividend, stock split,
                                   split-up or other distribution on shares of

                     in the applicable Conversion Price thereof, unless the
                     consideration per share (determined pursuant to Subsection
                     6(d)(v) below) for an Additional Share of Common Stock

<PAGE>   7

                     issue of such additional shares, or if prior to such
                     issuance, the Company receives written notice from the
                     holders of at least a majority of the voting power of all
                     then outstanding shares of Series A Preferred Stock, voting
                     together as a single class, agreeing that no such
                     adjustment shall be made as the result of the issuance of
                     Additional Shares of Common Stock.

              (iii)  Issue of Securities Deemed Issue of Additional Shares of
                     Common Stock. If the Company at any time or from time to
                     time after the Original Issue Date shall issue any Options
                     or Convertible Securities or Rights to Acquire Common
                     Stock, then the maximum number of shares of Common Stock
                     (as set forth in the instrument relating thereto without
                     regard to any provision contained therein for a subsequent
                     adjustment of such number) issuable upon the exercise of
                     such Options, Rights or, in the case of Convertible
                     Securities, the conversion or exchange of such Convertible
                     Securities, shall be deemed to be Additional Shares of
                     Common Stock issued as of the time of such issue; provided,
                     however, that Additional Shares of Common Stock shall not
                     be deemed to have been issued unless the consideration per
                     share (determined pursuant to Subsection 6(d)(v) hereof) of
                     such Additional Shares of Common Stock would be less than
                     the applicable Conversion Price in effect on the date of
                     and immediately prior to such issue, or such record date,
                     as the case may be, and provided, further, that in any such
                     case:

                     (A)   No further adjustment in the Conversion Price shall
                            be made upon the subsequent issue of shares of
                            Common Stock upon the exercise of such Options,
                            Rights or conversion or exchange of such Convertible
                            Securities;

                     (B)   Upon the expiration or termination of any unexercised
                            Option, Right or Convertible Security, the
                            Conversion Price shall be adjusted immediately to
                            reflect the applicable Conversion Price which would
                            have been in effect had such Option, Right or
                            Convertible Security (to the extent outstanding
                            immediately prior to such expiration or termination)
                            never been issued; and

                     (C)   In the event of any change in the number of shares of
                            Common Stock issuable upon the exercise, conversion
                            or exchange of any Option, Right or Convertible
                            Security, including, but not limited to, a change
                            resulting from the anti-dilution provisions thereof,
                            the Conversion Price then in effect shall forthwith
                            be readjusted to such Conversion Price as would have
                            obtained had the Conversion Price adjustment that
                            was originally made upon the issuance of such
                            Option, Right or Convertible Security which were not
                            exercised or converted prior to such change been
                            made upon the basis of such change, but no further
                            adjustment shall be made for the actual issuance of
                            Common Stock upon the exercise or conversion of any
                            such Option, Right or Convertible Security.

              (iv)   Adjustment of Conversion Price upon Issuance of Additional
                     Shares of Common Stock. If the Company shall at any time
                     after the Original Issue Date issue Additional Shares of
                     Common Stock (including Additional Shares of Common Stock
                     deemed to be issued pursuant to Subsection 6(d)(iii), but
                     excluding shares issued as a dividend or distribution as
                     provided in Subsection 6(e) or upon a stock split or
                     combination as provided in Subsection 6(d)), without
                     consideration, or for a consideration per share less than
                     the applicable Conversion Price in effect on the date of
                     and immediately prior to such issue, or without the
                     requisite number of notices

<PAGE>   8

                     contemplated by Subsection 6(d)(ii) hereof, then and in
                     such event, such Conversion Price shall be reduced,
                     concurrently with such issue to a price (calculated to the
                     nearest cent) determined by multiplying such Conversion
                     Price by a fraction, the numerator of which shall be the
                     number of shares of Common Stock outstanding immediately
                     prior to such issue plus the number of shares of Common
                     Stock which the aggregate consideration received by the
                     Company for the total number of Additional Shares of Common
                     Stock so issued would purchase at such Conversion Price;
                     and the denominator of which shall be the number of shares
                     of Common Stock outstanding immediately prior to such issue
                     plus the number of such Additional Shares of Common Stock
                     so issued.

                     Notwithstanding the foregoing, the applicable Conversion
                     Price shall not be reduced if the amount of such reduction
                     would be an amount less than $.05, but any such amount
                     shall be carried forward and reduction with respect thereto
                     made at the time of and together with any subsequent
                     reduction which, together with such amount and any other
                     amount or amounts so carried forward, shall aggregate $.05
                     or more.

              (v)    Determination of Consideration. For purposes of this
                     Subsection 6(d), the consideration received by the Company
                     for the issue of any Additional Shares of Common Stock
                     shall be computed as follows:

                     (A) Cash and Property. Such consideration shall:

                            (1)    insofar as it consists of cash, be computed
                                   at the aggregate of cash received by the
                                   Company, excluding amounts paid or payable
                                   for accrued interest or accrued dividends;

                            (2)    insofar as it consists of property other than
                                   cash, be computed at the fair market value
                                   thereof at the time of such issue, as
                                   determined in good faith by the Board; and

                            (3)    in the event Additional Shares of Common
                                   Stock are issued together with other shares
                                   or securities or other assets of the Company
                                   for consideration which covers both, be the
                                   proportion of such consideration so received,
                                   computed as provided in clauses (1) and (2)
                                   above, as determined in good faith by the
                                   Board.

                     (B) Options, Rights and Convertible Securities. The
                            consideration per share received by the Company for
                            Additional Shares of Common Stock deemed to have
                            been issued pursuant to Subsection 6(d)(iii),
                            relating to Options, Rights and Convertible
                            Securities, shall be determined by dividing

                            (1)    the total amount, if any, received or
                                   receivable by the Company as consideration
                                   for the issue of such Options, Rights or
                                   Convertible Securities, plus the minimum
                                   aggregate amount of additional consideration
                                   (as set forth in the instruments relating
                                   thereto, without regard to any provision
                                   contained therein for a subsequent adjustment
                                   of such consideration) payable to the Company
                                   upon the exercise of such Options, Rights or
                                   the conversion or exchange of such
                                   Convertible Securities, by

<PAGE>   9

                            (2)    the maximum number of shares of Common Stock
                                   (as set forth in the instruments relating
                                   thereto, without regard to any provision
                                   contained therein for a subsequent adjustment
                                   of such number) issuable upon the exercise of
                                   such Options, Rights or the conversion or
                                   exchange of such Convertible Securities.

       (e)    Adjustment for Stock Splits and Combinations. If the Company shall
              at any time or from time to time after the Original Issue Date
              effect a subdivision of the outstanding Common Stock, the
              Conversion Price then in effect immediately before that
              subdivision shall be proportionately decreased. If the Company
              shall at any time or from time to time after the Original Issue
              Date combine the outstanding shares of Common Stock, the
              Conversion Price then in effect immediately before the combination
              shall be proportionately increased. Any adjustment under this
              paragraph shall become effective at the close of business on the
              date the subdivision or combination becomes effective.

       (f)    Adjustment for Certain Dividends and Distributions. In the event
              the Company at any time or from time to time after the Original
              Issue Date shall make or issue a dividend or other distribution
              payable in Additional Shares of Common Stock, then and in each
              such event the Conversion Price shall be decreased as of the time
              of such issuance, by multiplying the Conversion Price by a
              fraction, the numerator of which shall be the total number of
              shares of Common Stock issued and outstanding immediately prior to
              the time of such issuance, and the denominator of which shall be
              the total number of shares of Common Stock issued and outstanding
              immediately prior to the time of such issuance plus the number of
              shares of Common Stock issuable in payment of such dividend or
              distribution.

       (g)    Adjustments for Other Dividends and Distributions. In the event
              the Company at any time, or from time to time after the Original
              Issue Date shall make or issue, a dividend or other distribution
              payable in securities of the Company other than shares of Common
              Stock, then and in each such event provision shall be made so that
              the holders of shares of the Series A Preferred Stock shall
              receive upon conversion thereof in addition to the number of
              shares of Common Stock receivable thereupon, the amount of
              securities of the Company that they would have received had their
              Series A Preferred Stock been converted into Common Stock on the
              date of such event and had thereafter, during the period from the
              date of such event to and including the Conversion Date, retained
              such securities receivable by them as aforesaid during such period
              given application to all adjustments called for during such
              period, under this paragraph with respect to the rights of the
              holders of the Series A Preferred Stock.

       (h)    Adjustment for Reclassification, Exchange, or Substitution. If the
              Common Stock issuable upon the conversion of the Series A
              Preferred Stock shall be changed into the same or a different
              number of shares of any class or classes of stock, whether by
              capital reorganization, reclassification, or otherwise (other than
              a subdivision or combination of shares or stock dividend provided
              for above), then and in each such event the holder of each share
              of Series A Preferred Stock shall have the right thereafter to
              convert such share into the kind and amount of shares of stock and
              other securities and property receivable upon such reorganization,
              reclassification, or other change, by holders of the number of
              shares of Common Stock into which such shares of Series A
              Preferred Stock might have been converted immediately prior to
              such reorganization, reclassification, or change, all subject to
              further adjustment as provided herein.

       (i)    No Impairment. The Company will not, by amendment of its
              Certificate of Incorporation or through any reorganization,
              transfer of assets, consolidation, merger, dissolution, issue or
              sale of securities or any other voluntary action, avoid or seek to
              avoid the observance or performance of any of the terms to be
              observed or performed hereunder by the Company, but will at all
              times in good faith assist in the carrying out of all the
              provisions of this Section 6 and in the taking of all such action
              as may be necessary or appropriate in order to protect the
              Conversion Rights of the holders of the Series A Preferred Stock
              against impairment to the extent required hereunder.

       (j)    Certificate as to Adjustments. Upon the occurrence of each
              adjustment or readjustment of the Conversion Price pursuant to
              this Section 6, the Company at its expense shall promptly compute
              such adjustment or readjustment in accordance with the terms
              hereof and furnish to each holder, if any, of Series A Preferred
              Stock outstanding a certificate setting forth such adjustment or
              readjustment and showing in detail the facts upon which such
              adjustment or readjustment is based and shall file a copy of such
              certificate with its corporate records. The Company shall, upon
              the reasonable written request of any holder of Series A Preferred
              Stock, furnish or cause to be furnished to such holder a similar
              certificate setting forth (i) such adjustments and readjustments,
              (ii) the Conversion Price then in effect, and (iii) the number of
              shares of Common Stock and the amount, if any, of other property
              which then would be received upon the conversion of Series A
              Preferred Stock. Despite such adjustment or readjustment, the form
              of each or all Series A Preferred Stock certificates, if the same
              shall reflect the initial or any subsequent Conversion Price, need
              not be changed in order for the adjustments or readjustments to be
              valid in accordance with the provisions of this Certificate, which
              shall control.

       (k)    Notice of Record Date. In the event

              (i)    that the Company declares a dividend (or any other
                     distribution) on its Common Stock payable in Common Stock
                     or other securities of the Company;

              (ii)   that the Company subdivides or combines its outstanding
                     shares of Common Stock;

              (iii)  of any reclassification of the Common Stock of the Company
                     (other than a subdivision or combination of its outstanding
                     shares of Common Stock or a stock dividend or stock
                     distribution thereon); or

              (iv)   of the involuntary or voluntary dissolution, liquidation or
                     winding up of the Company;

       then the Company shall cause to be filed at its principal office or at
the office of the transfer agent of the Series A Preferred Stock, and shall
cause to be mailed to the holders of the Series A Preferred Stock at their last
addresses as shown on the records of the Company, or such transfer agent, at
least 10 days prior to the record date specified in (A) below or 20 days before
the date specified in (B) below, a notice stating

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

<PAGE>   11

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

SECTION 7.    REDEMPTION.

       (a)    Upon the third anniversary of the closing of the Original Issue
Date (as defined in Section 6(d)(i) above), the Company at its option may
redeem, out of its available cash or cash equivalents, any amount of the then
outstanding and not previously converted (pursuant to Section 6) Series A
Preferred Stock issued on the Original Issue Date, at a price per share equal to
the Original Series A Issue Price, plus any declared, but unpaid dividends
thereon. At any time subsequent to the third anniversary of the Original Issue
Date, the Company at its option may redeem, out of its available cash or cash
equivalents, any amount of the then outstanding and not previously converted
(pursuant to Section 6) Series A Preferred Stock exchanged on the Original
Closing Date, at a price per share equal to the Original Series A Issue Price,
plus any declared, but unpaid dividends thereon, upon notice provided in
accordance with Section 7(b). Shares subject to redemption pursuant to this
Section shall be redeemed from each holder of Series A Preferred Stock on a pro
rata basis.

       (b)    At least thirty (30) days prior to the dates that the Company
elects to redeem shares of the Series A Preferred Stock pursuant to Section 7(a)
(each a "Redemption Date," together the "Redemption Dates"), the Company shall
send a notice (the "Redemption Notice") to all holders of the outstanding Series
A Preferred Stock of such redemption to be effected, specifying the number of
shares to be redeemed from such holder, the Redemption Date, the price per share
to be paid (the "Redemption Price") and the place at which payment may be
obtained.

       (c)    On or prior to the Redemption Date, the Company shall deposit the
Redemption Price of all shares to be redeemed as of such date with a bank or
trust company having aggregate capital and surplus in excess of $50,000,000, as
a trust fund, with irrevocable instructions and authority to the bank or trust
company to pay, upon receipt of notice from the Company that such holder has
surrendered the Series A Preferred Stock share certificates in accordance with
Section 7(d), the Redemption Price of the shares to their respective holders.
Any moneys deposited by the Company pursuant to this Section 7 for the
redemption of shares thereafter converted into shares of Common Stock pursuant
to Section 6 hereof no later than the fifth (5th) day preceding the Redemption
Date shall be returned to the Company forthwith upon such conversion. The
balance of any funds deposited by the Company pursuant to this Section 7
remaining unclaimed at the expiration of one (1) year following such Redemption
Date shall be returned to the Company promptly upon its written request.

       (d)    On such Redemption Date, each holder of shares of Series A
Preferred Stock to be redeemed shall surrender such holder's certificates
representing such shares to the Company in the manner and at the place
designated in the Redemption Notice, and thereupon the Redemption Price of such
shares shall be payable to the order of the person whose name appears on such
certificate or certificates as the owner thereof and each surrendered
certificate shall be canceled. In the event less than all the shares represented
by such certificates are redeemed, a new certificate shall be issued
representing the unredeemed shares. From and after such Redemption Date, all
rights of the holder of such shares as a holder of Series A Preferred Stock
(except the right to receive the Redemption Price without interest upon
surrender of their certificates), shall cease and terminate with respect to such
shares.

       (e)    In the event of a call for redemption of any shares of Series A
Preferred Stock, the Conversion Rights (as defined in Section 6) for such Series
A Preferred Stock shall terminate as to the shares designated for redemption at
the close of business on the fifth (5th) day preceding the Redemption Date,
unless default is made in payment of the Redemption Price.
