     the Shareholders' Agreement, the Business Plan nor any Ancillary
     Agreements, nor any other statements, certificates or documents made or
     delivered in connection herewith or therewith, contains any untrue
     statement of a material fact or omits to state a material fact necessary to

     however, the Company does not warrant that it will achieve such financial
     projections.

     labor union has requested or, to the knowledge of the Company, has sought

     threatened, which could have a Material Adverse Effect nor is the Company
     aware of any labor organization activity involving its employees. The
     Company is not aware that any officer or key employee, or that any group of
     key employees, intends to terminate their employment with the Company or
     its Subsidiaries, nor does the Company or any of its Subsidiaries have a
     present intention to terminate the employment of any of the foregoing.

     Company. Except as disclosed in the Financial Statements, neither the
     Company nor any of its Subsidiaries is a guarantor or indemnitor of any

     such employee's best efforts to promote the interests of the Company and
     its Subsidiaries or that would conflict with the Company's or any
     Subsidiary's business as proposed to be conducted. Neither the execution
     nor delivery of this Agreement, nor the carrying on of the Company's or any
     Subsidiary's business by the employees of the Company or such Subsidiary,
     nor the conduct of the Company's or such Subsidiary's business as proposed,
     will, to the best of the Company's knowledge, conflict with or result in a
     breach of the terms, conditions or provisions of, or constitute a default
     under, any contract covenant or instrument under which any of such
     employees is now obligated. The Company does not believe it is or will be
     necessary to use any inventions of any of its employees (or persons it
     currently intends to hire) made prior to the employment of such employees
     by the Company or any of its Subsidiaries.

     maintain, contribute to or have any material liability with respect to any

     plan or arrangements (collectively, "Plans") that are subject to the
     provisions of the Employee Retirement Income Security Act of 1974, as
     amended, and the rules and regulations thereunder ("ERISA"). All Plans are
     in compliance in all material respects with all applicable laws, including
     but not limited to ERISA and the Internal Revenue Code of 1986, as amended
     (the "Code"), and have been operated and administered in all material
     respects in accordance with their terms. No Plan is a defined benefit plan
     or multiemployer plan. The Company does not provide retiree life and/or
     retiree health benefits or coverage for any employee or any beneficiary of
     any employee after such employee's termination of employment except as
     required by Section 4980B of the Code or under a Plan which is intended to
     be "qualified" under Section 401(a) of the Code. No Plan has been involved
     in any prohibited transaction under Section 406 of ERISA or Section 4975 of
     the Code. Full payment has been made of all amounts which the Company or
     any of its Subsidiaries were required under the terms of the Plans to have
     paid as contributions to such Plans on or prior to the date hereof

     or litigation has been incurred, made commenced or, to the knowledge of the
     Company, threatened, by or against the Company or any of its Subsidiaries
     with respect to any Plan (other than for benefits payable in the ordinary
     course). No material liability has been, or could reasonably be expected to
     be, incurred under Title IV of ERISA or Section 4001(b) of ERISA and/or
     Section 414(b) of (c) of the Code (and the regulations promulgated
     thereunder) with respect to any "employee pension benefit plan" which is
     not a Plan. As used in this subsection, the terms "defined benefit plan,"
     "employee benefit plan," "employee pension benefit plan," "employee welfare
     benefit plan" and "multiemployer plan" shall have the respective meanings
     assigned to such terms in Section 3 of ERISA.

     binding obligation, enforceable in accordance with its terms.

          3.2 Purchase Entirely for Own Account. This Agreement is made with
     each Investor in reliance upon such Investor's representation to the
     Company, which by such Investor's execution of this Agreement such Investor
     hereby confirms, that the Series A Preferred Stock to be received by such
     Investor and the Common Stock issuable upon conversion thereof
     (collectively, the "Securities") will be acquired for investment for such
     Investor's own account, not as a nominee or agent, and not with a view to
     the resale or distribution of any part thereof, and that such Investor has
     no present intention of selling, granting any participation in, or
     otherwise distributing the same. By executing this Agreement, each Investor
     further represents that such Investor does not have any contract,
     undertaking, agreement or arrangement with any person to sell, transfer or
     grant participations to such person or to any third person, with respect to
     any of the Securities. Each Investor represents that it has full power and
     authority to enter into this Agreement.

          3.3 Disclosure of Information. Such Investor believes it has received
     all of the information it considers necessary or appropriate for deciding
     whether to purchase the Series A Preferred Stock. Each Investor further
     represents that it has had an opportunity to ask questions and receive
     answers from the Company regarding the terms and conditions of the offering
     of the Series A Preferred Stock. The foregoing, however, does not limit or
     modify the representations and warranties of the Company in Section 2 of
     this Agreement or the right of the Investors to rely thereon.

          3.4 Investment Experience. Such Investor is an investor in securities
     of companies in the development stage and acknowledges that it is able to
     fend for itself, can bear the economic risk of its investment and has such

          3.6 Restricted Securities. Such Investor understands that the shares
     of Series A Preferred Stock it is purchasing are characterized as
     "restricted securities" under the federal securities laws inasmuch as they
     are being acquired from the Company in a transaction not involving a public
     offering and that under such laws and applicable regulations such
     securities may be resold without registration under the Securities Act,
     only in certain limited circumstances. In this connection, each

     the representations set forth above, each Investor further agrees not to
     make any disposition of all or any portion of the Series A Preferred Stock

     bound by this Section 3.7, to the extent such section is then applicable,

          proposed disposition and shall have furnished the Company with a
          detailed statement of the circumstances surrounding the proposed

          above, no such registration statement or opinion of counsel shall be
          necessary for a transfer without value by an Investor which is a
          partnership to a partner of such partnership or a retired partner of

          the Securities Act) of such Investor, if the transferee agrees in
          writing to be subject to the terms hereof to the same extent as if he
          were an original Investor hereunder.

          3.8 Legends. It is understood that the certificates evidencing the
     Series A Preferred Stock (and the Common Stock issuable upon conversion
     thereof) may bear one or all of the following legends:

          effect with respect to the securities under such Act or an opinion of
          counsel satisfactory to the Company that such registration is not
          required or unless sold pursuant to Rule 144 of such Act."

     payment of any dividend (payable other than in Common Stock or other
     securities and rights convertible into or entitling the holder thereof to
     receive, directly or indirectly, additional shares of Common Stock of this
     corporation) on the Common Stock of this corporation, at the rate of $1.20
     per share of Series A Preferred Stock (subject to appropriate adjustments
     for stock splits, stock dividends, combinations or other recapitalizations
     with respect to such shares) per annum (the "Preferred Dividend
     Preference"). Such dividends shall not be cumulative and shall be payable
     when, as and if declared by the Board of Directors.
<PAGE>

          (b) After paying the full Preferred Dividend Preference in any
     calendar year, whenever this corporation declares a further dividend in
     such calendar year, the holders of Common Stock and the holders of Series A
     Preferred Stock shall be entitled to receive dividends ratably based on the
     number of shares of Common Stock held by each on an as-if-converted to
     Common Stock basis.

     4. Liquidation Preference.

          (a) In the event of any liquidation, dissolution or winding up of this
     corporation, either voluntary or involuntary, subject to the rights of
     series of Preferred Stock that may from time to time come into existence,
     the holders of Series A Preferred Stock shall be entitled to receive, prior
     and in preference to any distribution of any of the assets of this
     corporation to the holders of Common Stock by reason of their ownership
     thereof, an amount per share equal to the sum of (i) $15.00 for each
     outstanding share of Series A Preferred Stock (subject to appropriate
     adjustments for stock splits, stock dividends, combinations or other
     recapitalizations with respect to such shares and hereafter referred to as
     the "Original Series A Issue Price"), and (ii) an amount equal to declared
     but unpaid dividends on such share. If upon the occurrence of such event,
     the assets and funds thus distributed among the holders of the Series A
     Preferred Stock shall be insufficient to permit the payment to such holders
     of the full aforesaid preferential amounts, then, subject to the rights of
     series of Preferred Stock that may from time to time come into existence,
     the entire assets and funds of the corporation legally available for
     distribution shall be distributed ratably among the holders of the Series A
     Preferred Stock in proportion to the preferential amount each such holder
     would otherwise be entitled to receive.

          (b) Upon the completion of the distribution required by subsection (a)
     of this Section 4, the remaining assets of the corporation available for
     distribution to shareholders shall be distributed among the holders of
     Series A Preferred Stock and Common Stock pro rata based on the number of
     shares of Common Stock held by each (assuming conversion of all such Series
     A Preferred Stock) until the holders of Series A Preferred Stock shall have
     received an aggregate of $7.50 per share (not including amounts paid
     pursuant to subsection (a) of this Section 4); thereafter, if assets remain
     in this corporation, the holders of the Common Stock of this corporation
     shall receive all of the remaining assets of this corporation pro rata
     based on the number of shares of Common Stock held by each.

               (c)(i) A consolidation or merger of this corporation with or into
          any other corporation or corporations (other than any merger effected
          solely for the purpose of changing the domicile of the corporation),
          or a sale, conveyance or disposition of all or substantially all of
          the assets of this corporation or the effectuation by the corporation
          of a transaction or series of related transactions in which more than
          50% of the voting power of the corporation is disposed of, shall be
          deemed to be a liquidation, dissolution or winding up within the
          meaning of this Section 4.

               (ii) In any of such events, if the consideration received by the
          corporation is other than cash, its value will be deemed its fair
          market value. Any securities shall be valued as follows:


                                      -2-
<PAGE>

                    (A) Securities not subject to investment letter or other
               similar restrictions on free marketability covered by (B) below
               shall be valued as follows:

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

                         (2) 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) trading days prior to the closing;
                    and

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

                    (B) 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
               shareholder's status as an affiliate or former affiliate) shall
               be to make an appropriate discount from the market value
               determined as above in (A) (1), (2) or (3) to reflect the
               approximate fair market value thereof, as mutually determined by
               the Board of Directors and the holders of at least a majority of
               the voting power of all then outstanding shares of such Series A
               Preferred Stock.

               (iii) In the event the requirements of this subsection 4(c) are
          not complied with, this corporation shall forthwith either:

                    (A) cause such closing to be postponed until such time as
               the requirements of this subsection 4(c) have been complied with;
               or

                    (B) cancel such transaction, in which event the rights,
               preferences and privileges of the holders of the Series A
               Preferred Stock shall revert to and be the same as such rights,
               preferences and privileges existing immediately prior to the date
               of the first notice referred to in subsection 4(c)(iv) hereof.

               (iv) The corporation shall give each holder of record of Series A
          Preferred Stock written notice of such impending transaction not later
          than thirty (30) days prior to the shareholders' meeting called to
          approve such transaction, or thirty (30) days prior to the closing of
          such transaction, whichever is earlier, and shall also notify such
          holders in writing of the final approval of such transaction. The
          first of such notices shall describe the material terms and conditions
          of the impending transaction and the provisions of this Section 4, and
          the corporation shall thereafter give such holders prompt notice of
          any material changes. The transaction shall in no event take place
          sooner than thirty (30) days


                                      -3-
<PAGE>

          after the corporation has given the first notice provided for herein
          or sooner than ten (10) days after the corporation has given notice of
          any material changes provided for herein; provided, however, that such
          periods may be shortened upon the written consent of the holders of
          Series A Preferred Stock that are entitled to such notice rights or
          similar notice rights and that represent at least a majority of the
          voting power of all then outstanding shares of such Series A Preferred
          Stock.

               (v) Any notice required by the provisions of this Section 4 to be
          given to the holders of shares of Series A Preferred Stock shall be
          deemed given when deposited in the United States mail, postage
          prepaid, and addressed to each holder of record at his address
          appearing on the books of this corporation.

               (vi) The provisions of this Section 4 are in addition to the
          protective provisions of Section 8 hereof.

     5. Redemption.

          (a) At any time after February 12, 2002, but within forty-five (45)
     days (the "Redemption Date") after the receipt by this corporation of a
     written request from the holders of not less than a majority of the then
     outstanding shares of Series A Preferred Stock that all of such holders'
     shares be redeemed, and immediately prior to the surrender by such holders
     of the certificates representing such shares, this corporation shall, to
     the extent it may lawfully do so, redeem all of the then outstanding shares
     of Series A Preferred Stock by paying in cash therefor a sum per share
     equal to the Original Series A Issue Price (as adjusted for any stock
     dividends, combinations or splits with respect to such share) plus an
     amount equal to all declared but unpaid dividends on such share as of the
     Redemption Date (the "Redemption Price") to the holders of the Series A
     Preferred Stock in three equal annual installments beginning on the
     Redemption Date. Any redemption effected pursuant to this subsection 5(a)
     shall be made on a pro rata basis among the holders of the Series A
     Preferred Stock in proportion to the number of shares of Series A Preferred
     Stock then held by such holders.

          (b) Not less than twenty (20) days prior to the Redemption Date,
     written notice shall be mailed, first class postage prepaid, to each holder
     of record (at the close of business on the business day next preceding the
     day on which notice is given) of the Series A Preferred Stock at the
     address last shown on the records of this corporation for such holder,
     notifying such holder of the redemption to be effected, specifying the
     number of shares to be redeemed from such holder (which shall be all of the
     shares of Series A Preferred Stock held by such holder), the Redemption
     Date, the Redemption Price, the place at which payment may be obtained and
     calling upon such holder to surrender to this corporation, in the manner
     and at the place designated, his, her or its certificate or certificates
     representing all of the shares of the Series A Preferred Stock held by such
     holder (the "Redemption Notice"). Except as provided in subsection 5(c)
     hereof, on or after the Redemption Date, each holder of Series A Preferred
     Stock shall surrender to this corporation the certificate or certificates
     representing such shares, 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


                                      -4-
<PAGE>

     appears on such certificate or certificates as the owner thereof and each
     surrendered certificate shall be cancelled.

          (c) From and after the Redemption Date, unless there shall have been a
     default in payment of the Redemption Price, all rights of the holders of
     shares of Series A Preferred Stock designated in the Redemption Notice as
     holders of Series A Preferred Stock (except the right to receive the
     respective Redemption Price without interest upon surrender of their
     certificate or certificates) shall cease with respect to such shares, and
     such shares shall not thereafter be transferred on the books of this
     corporation or be deemed to be outstanding for any purpose whatsoever. If
     the funds of the corporation legally available for redemption of shares of
     Series A Preferred Stock on the Redemption Date, or any subsequent date on
     which payment is due the holders of Series A Preferred Stock pursuant to
     this Section 5, are insufficient to redeem the total number of shares of
     Series A Preferred Stock on such date, those funds which are legally
     available will be used to redeem the maximum possible number of such shares
     ratably among the holders of the Series A Preferred Stock in proportion to
     the amount of such stock owned by each such holder. At any time thereafter
     when additional funds of the corporation are legally available for the
     redemption of shares of Series A Preferred Stock, such funds will
     immediately be used to redeem the balance of the shares which the
     corporation has become obliged to redeem on the Redemption Date but which
     it has not redeemed. Notwithstanding anything herein to the contrary, the
     number of shares of Series A Preferred Stock for which the corporation has
     not yet paid the full Redemption Price as of any date after the Redemption
     Date shall remain outstanding and entitled to all the rights and
     preferences provided herein.

     6. Conversion. 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 after the date of issuance of such share at the office of this
     corporation or any transfer agent for such stock, 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 at the time in
     effect for such share. The initial Conversion Price per share for shares of
     Series A Preferred Stock shall be the Original Series A Issue Price;
     provided, however, that the Conversion Price for the Series A Preferred
     Stock shall be subject to adjustment as set forth in subsection 6(d).

          (b) Automatic Conversion. Each share of Series A Preferred Stock shall
     automatically be converted into shares of Common Stock at the Conversion
     Price at the time in effect for such Series A Preferred Stock immediately
     and without further action by the corporation or the holder of such shares
     of Series A Preferred Stock upon the earlier of (i) the corporation's sale
     of its Common Stock in a firm commitment underwritten public offering
     pursuant to a registration statement under the Securities Act of 1933, as
     amended, the public offering price of which is not less than $20.00 per
     share (subject to appropriate adjustments for stock splits, stock
     dividends, combinations or other recapitalizations with respect to such
     shares) and $15,000,000 in the aggregate or (ii) the date specified


                                      -5-
<PAGE>

     by written consent or agreement of the holders of two-thirds (2/3) of the
     then outstanding shares of Series A Preferred Stock.

          (c) Mechanics of Conversion. Before any holder of Series A Preferred
     Stock shall be entitled to convert the same into shares of Common Stock, he
     shall surrender the certificate or certificates therefor, duly endorsed, at
     the office of this corporation or of any transfer agent for the Series A
     Preferred Stock, and shall give written notice to this corporation at its
     principal corporate office, of the election to convert the same and shall
     state therein the name or names in which the certificate or certificates
     for shares of Common Stock are to be issued. This corporation shall, as
     soon as practicable thereafter, issue and deliver at such office to such
     holder of Series A Preferred Stock, or to the nominee or nominees of such
     holder, a certificate or certificates for the number of shares of Common
     Stock to which such holder shall be entitled as aforesaid. Such conversion
     shall be deemed to have been made immediately prior to the close of
     business on the date of such surrender of the shares of Series A Preferred
     Stock to be converted, and the person or persons entitled to receive the
     shares of Common Stock issuable upon such conversion shall be treated for
     all purposes as the record holder or holders of such shares of Common Stock
     as of such date. If the conversion is in connection with an underwritten
     offering of securities registered pursuant to the Securities Act of 1933,
     as amended, the conversion may, at the option of any holder tendering
     Series A Preferred Stock for conversion, be conditioned upon the closing
     with the underwriters of the sale of securities pursuant to such offering,
     in which event the person(s) entitled to receive the Common Stock upon
     conversion of the Series A Preferred Stock shall not be deemed to have
     converted such Series A Preferred Stock until immediately prior to the
     closing of such sale of securities.

          (d) Conversion Price Adjustments of Series A Preferred Stock. The
     Conversion Price of the Series A Preferred Stock shall be subject to
     adjustment from time to time as follows:

                    (i)(A) Upon the issuance by the corporation of any
               Additional Stock (as defined below) after the date upon which any
               shares of the Series A Preferred Stock were first issued (the
               "Purchase Date"), without consideration or for a consideration
               per share less than the Conversion Price for the Series A
               Preferred Stock in effect immediately prior to the issuance of
               such Additional Stock, the Conversion Price for the Series A
               Preferred Stock in effect immediately prior to each such issuance
               shall forthwith (except as otherwise provided in this clause (i))
               be adjusted to a price 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
               issuance (excluding the number of shares of Common Stock issuable
               upon the conversion of the Series A Preferred Stock) plus the
               number of shares of Common Stock that the aggregate consideration
               received by the corporation for such issuance would purchase at
               the Conversion Price existing immediately prior to such issuance
               of Additional Stock, and the denominator of which shall be the
               number of shares of Common Stock outstanding immediately prior to
               such issuance (excluding the number of shares of Common Stock
               issuable upon the conversion of the Series A Preferred Stock)
               plus the number of shares of such Additional Stock. However, the
               foregoing calculation shall not take into account shares deemed
               issued pursuant to Section 6(d)(i)(E) on account of options,
               rights or convertible or exchangeable securities


                                      -6-
<PAGE>

               (or the actual or deemed consideration therefor), except to the
               extent (1) such options, rights or convertible or exchangeable
               securities have been exercised, converted or exchanged or (2) the
               consideration to be paid upon such exercise or exchange per share
               of underlying Common Stock, or the conversion price then in
               effect for convertible securities, is less than or equal to the
               per share consideration for the Additional Stock which has given
               rise to the Conversion Price adjustment being calculated.

                    (B) No adjustment of the Conversion Price for the Series A
               Preferred Stock shall be made in an amount less than one cent per
               share, provided that any adjustments which are not required to be
               made by reason of this sentence shall be carried forward and
               shall be either taken into account in any subsequent adjustment
               made prior to 3 years from the date of the event giving rise to
               the adjustment being carried forward, or shall be made at the end
               of 3 years from the date of the event giving rise to the
               adjustment being carried forward. Except to the limited extent
               provided for in subsections 6(d)(i)(E)(3) and (E)(4), no
               adjustment of the Conversion Price pursuant to this subsection
               6(d)(i) shall have the effect of increasing the Conversion Price
               above the Conversion Price in effect immediately prior to such
               adjustment.

                    (C) In the case of the issuance of Additional Stock for
               cash, the consideration shall be deemed to be the amount of cash
               paid therefor before deducting any reasonable discounts,
               commissions or other expenses allowed, paid or incurred by this
               corporation for any underwriting or otherwise in connection with
               the issuance and sale thereof.

                    (D) In the case of the issuance of Additional Stock for a
               consideration in whole or in part other than cash, the
               consideration other than cash shall be deemed to be the fair
               value thereof as determined by the Board of Directors
               irrespective of any accounting treatment.

                    (E) In the case of the issuance (whether before, on or after
               the applicable Purchase Date) of options to purchase or rights to
               subscribe for Common Stock, securities by their terms convertible
               into or exchangeable for Common Stock or options to purchase or
               rights to subscribe for such convertible or exchangeable
               securities, the following provisions shall apply for all purposes
               of this subsection 6(d)(i) and subsection 6(d)(ii):

                         (1) The aggregate maximum number of shares of Common
                    Stock deliverable upon exercise (assuming the satisfaction
                    of any conditions to exercisability, including without
                    limitation, the passage of time, but without taking into
                    account potential antidilution adjustments) of such options
                    to purchase or rights to subscribe for Common Stock shall be
                    deemed to have been issued at the time such options or
                    rights were issued and for a consideration equal to the
                    consideration (determined in the manner provided in
                    subsections 6(d)(i)(C) and (d)(i)(D)), if any, received by
                    the corporation upon the issuance of such options or rights
                    plus the minimum exercise price provided in such options or
                    rights (without taking into account potential antidilution
                    adjustments) for the Common Stock covered thereby.

<PAGE>

                         (2) The aggregate maximum number of shares of Common
                    Stock deliverable upon conversion of or in exchange
                    (assuming the satisfaction of any conditions to
                    convertibility or exchangeability, including, without
                    limitation, the passage of time, but without taking into
                    account potential antidilution adjustments) for any such
                    convertible or exchangeable securities or upon the exercise
                    of options to purchase or rights to subscribe for such
                    convertible or exchangeable securities and subsequent
                    conversion or exchange thereof shall be deemed to have been
                    issued at the time such securities were issued or such
                    options or rights were issued and for a consideration equal
                    to the consideration, if any, received by the corporation
                    for any such securities and related options or rights
                    (excluding any cash received on account of accrued interest
                    or accrued dividends), plus the minimum additional
                    consideration, if any, to be received by the corporation
                    (without taking into account potential antidilution
                    adjustments) upon the conversion or exchange of such
                    securities or the exercise of any related options or rights
                    (the consideration in each case to be determined in the
                    manner provided in subsections 6(d)(i)(C) and (d)(i)(D)).

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

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

                    (ii) "Additional Stock" shall mean any shares of Common
               Stock issued (or deemed to have been issued pursuant to
               subsection 6(d)(i)(E)) by this corporation after the Purchase
               Date for the Series A Preferred Stock other than:

                         (A) Common Stock issued pursuant to a transaction
                    described in subsection 6(d)(iii) hereof, or

                         (B) shares of Common Stock issued upon conversion of
                    the Series A Preferred Stock, or


                                      -8-
<PAGE>

                         (C) shares of Common Stock (or options, warrants or
                    other rights to purchase such Common Stock) issuable or
                    issued to employees, consultants, directors or vendors (if
                    in transactions with primarily non-financing purposes) of
                    this corporation directly or pursuant to a stock option plan
                    or restricted stock plan approved by the shareholders and
                    Board of Directors of this corporation at any time when the
                    total number of shares of Common Stock so issuable or issued
                    (and not repurchased at cost by the corporation in
                    connection with the termination of employment or commercial
                    relationship) does not exceed 1,000,000 or

                         (D) shares of Common Stock issued or issuable (I) in a
                    public offering before or in connection with which all
                    outstanding shares of Series A Preferred Stock will be
                    converted to Common Stock or (II) upon exercise of warrants
                    or rights granted to underwriters in connection with such a
                    public offering.

                         (E) up to 478,500 shares of Common Stock issued to
                    ITALADE TECHNOLOGY (THAILAND) LIMITED ("ITALADE") pursuant
                    to that joint venture agreement dated as of April 4, 1997
                    between the corporation and ITALADE.

                    (iii) In the event the corporation should at any time or
               from time to time after the Purchase Date fix a record date for
               the effectuation of a split or subdivision of the outstanding
               shares of Common Stock or the determination of holders of Common
               Stock entitled to receive a dividend or other distribution
               payable in additional shares of Common Stock or other securities
               or rights convertible into, or entitling the holder thereof to
               receive directly or indirectly, additional shares of Common Stock
               (hereinafter referred to as "Common Stock Equivalents") without
               payment of any consideration by such holder for the additional
               shares of Common Stock or the Common Stock Equivalents (including
               the additional shares of Common Stock issuable upon conversion or
               exercise thereof), then, as of such record date (or the date of
               such dividend, distribution, split or subdivision if no record
               date is fixed), the Conversion Price of the Series A Preferred
               Stock shall be appropriately decreased so that the number of
               shares of Common Stock issuable on conversion of each share of
               such series shall be increased in proportion to such increase of
               the aggregate number of shares of Common Stock outstanding and
               those issuable with respect to such Common Stock Equivalents.

                    (iv) If the number of shares of Common Stock outstanding at
               any time after the Purchase Date is decreased by a combination of
               the outstanding shares of Common Stock, then, following the
               record date of such combination, the Conversion Price for the
               Series A Preferred Stock shall be appropriately increased so that
               the number of shares of Common Stock issuable on conversion of
               each share of such series shall be decreased in proportion to
               such decrease in outstanding shares.

          (e) Other Distributions. In the event this corporation shall declare a
     distribution payable in securities of other persons, evidences of
     indebtedness issued by this corporation or other persons, assets (excluding
     cash dividends) or options or rights not referred to in subsection
     6(d)(iii), then, in each such case for the purpose of this subsection 6(e),
     the holders of the Series A Preferred Stock shall be entitled to a
     proportionate share of any such distribution as though they were the
     holders


                                      -9-
<PAGE>

     of the number of shares of Common Stock of the corporation into which their
     shares of Series A Preferred Stock are convertible as of the record date
     fixed for the determination of the holders of Common Stock of the
     corporation entitled to receive such distribution.

          (f) Recapitalizations. If at any time or from time to time there shall
     be a recapitalization of the Common Stock (other than a subdivision,
     combination or merger or sale of assets transaction provided for elsewhere
     in this Section 6 or Section 4) provision shall be made so that each holder
     of Series A Preferred Stock shall thereafter be entitled to receive upon
     conversion of the Series A Preferred Stock the number of shares of stock or
     other securities or property of the Company or otherwise, to which a holder
     of the Common Stock deliverable upon conversion of such holder's Series A
     Preferred Stock would have been entitled on such recapitalization. In any
     such case, appropriate adjustment shall be made in the application of the
     provisions of this Section 6 with respect to the rights of the holders of
     the Series A Preferred Stock after the recapitalization to the end that the
     provisions of this Section 6 (including adjustment of the Conversion Price
     then in effect for the Series A Preferred Stock and the number of shares
     purchasable upon conversion of the Series A Preferred Stock) shall be
     applicable after that event as nearly equivalent as may be practicable.

          (g) No Impairment. This corporation will not, by amendment of its
     Articles of Incorporation or through any reorganization, recapitalization,
     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 this corporation, 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.

          (h) No Fractional Shares and Certificate as to Adjustments.

               (i) No fractional shares shall be issued upon the conversion of
          any share or shares of the Series A Preferred Stock, and the number of
          shares of Common Stock to be issued shall be rounded to the nearest
          whole share. Whether or not fractional shares are issuable upon such
          conversion shall be determined on the basis of the total number of
          shares of Series A Preferred Stock the holder is at the time
          converting into Common Stock and the number of shares of Common Stock
          issuable upon such aggregate conversion.

               (ii) Upon the occurrence of each adjustment or readjustment of
          the Conversion Price of the Series A Preferred Stock pursuant to this
          Section 6, this corporation, at its expense, shall promptly compute
          such adjustment or readjustment in accordance with the terms hereof
          and prepare and furnish to each holder of Series A Preferred Stock a
          certificate setting forth such adjustment or readjustment and showing
          in detail the facts upon which such adjustment or readjustment is
          based. This corporation shall, upon the written request at any time of
          any holder of Series A Preferred Stock, furnish or cause to be
          furnished to such holder a like certificate setting forth (A) such
          adjustment and readjustment, (B) the Conversion Price of the Series A
          Preferred Stock held by such


                                      -10-
<PAGE>

          holder at the time in effect, and the number of shares of Common Stock
          and the amount, if any, of other property which at the time would be
          received upon the conversion of a share of Series A Preferred Stock.

          (i) Notices of Record Date. In the event of any taking by this
     corporation of a record of the holders of any class of securities for the
     purpose of determining the holders thereof who are entitled to receive any
     dividend (other than a cash dividend) or other distribution, any right to
     subscribe for, purchase or otherwise acquire any shares of stock of any
     class or any other securities or property, or to receive any other right,
     this corporation shall mail to each holder of Series A Preferred Stock, at
     least 20 days prior to the date specified therein, a notice specifying the
     date on which any such record is to be taken for the purpose of such
     dividend, distribution or right, and the amount and character of such
     dividend, distribution or right.

          (j) Reservation of Stock Issuable Upon Conversion. This corporation
     shall at all times reserve and keep available out of its authorized but
     unissued shares of Common Stock, solely for the purpose of effecting the
     conversion of the shares of the Series A Preferred Stock, such number of
     its shares of Common Stock as shall from time to time be sufficient to
     effect the conversion of all outstanding shares of the Series A Preferred
     Stock. If at any time the number of authorized but unissued shares of
     Common Stock shall not be sufficient to effect the conversion of all then
     outstanding shares of the Series A Preferred Stock, in addition to such
     other remedies as shall be available to the holder of such Series A
     Preferred Stock, this corporation will take such corporate action as may,
     in the opinion of its counsel, be necessary to increase its authorized but
     unissued shares of Common Stock to such number of shares as shall be
     sufficient for such purposes, including, without limitation, using its best
     efforts to obtain the requisite shareholder approval of any necessary
     amendment to the corporation's Articles of Incorporation.

          (k) Notices. Unless otherwise provided, any notice required or
     permitted under this Section 6 shall be given in writing and shall be
     deemed effectively given upon personal or facsimile delivery to the party
     to be notified or upon deposit with the United States Post Office, by
     registered or certified mail, or with a nationally recognized overnight
     delivery service, postage prepaid and addressed to each holder of record at
     his address appearing on the books of this corporation.

     7. Voting Rights. The holder of each share of Series A Preferred Stock
shall have the right to one vote for each share of Common Stock into which such
Series A Preferred Stock could then be converted, and with respect to such vote,
such holder shall have full voting rights and powers equal to the voting rights
and powers of the holders of Common Stock, and shall be entitled,
notwithstanding any provision hereof, to notice of any shareholders' meeting in
accordance with the Bylaws of this corporation, and shall be entitled to vote,
together with holders of Common Stock, with respect to any question upon which
holders of Common Stock have the right to vote. Fractional votes shall not be
permitted and any fractional voting rights available on an as-converted basis
(after aggregating all shares into which shares of the Series A Preferred Stock
held by each holder could be converted) shall be rounded to the nearest whole
number (with one-half being rounded upward).


                                      -11-
<PAGE>

     8. Protective Provisions. Subject to the rights of series of Preferred
Stock which may from time to time come into existence, so long as any shares of
Series A Preferred Stock are outstanding, this corporation shall not without
first obtaining the approval (by vote or written consent, as provided by law) of
the holders of at least two thirds (66.67%) of the then outstanding shares of
Series A Preferred Stock:

          (a) sell, convey, or otherwise dispose of or encumber all or
     substantially all of its property or business or merge with and into any
     other corporation where the corporation is not the surviving corporation

     transaction or series of related transactions in which more than fifty
     percent (50%) of the voting power of the corporation is disposed of, or
     effect any voluntary liquidation, dissolution or winding up of the
     corporation or recapitalization of the corporation; or

          (b) alter or change the rights, preferences or privileges of the
     shares of Series A Preferred Stock so as to adversely affect such shares;
     or

          (c) increase or decrease (other than by redemption or conversion) the
     total number of authorized shares of capital stock or any series of capital
     stock, provided, however, that no such approval shall be required to
     increase the total number of authorized shares of Common Stock to less than
     or equal to fifteen million (15,000,000) shares; or

          (d) authorize or issue, or obligate itself to issue, any equity
     security, including any other security convertible into or exercisable for
     any equity security, (i) having a preference over, or being on a parity
     with, the rights, preferences and privileges of the Series A Preferred
     Stock with respect to dividends, liquidation or voting (provided that
     additional shares of Common Stock having the same number of votes per share
     as the Series A Preferred Stock may be issued), or (ii) having rights
     similar to any of the rights of the Series A Preferred Stock under this
     Section 8; or

          (e) redeem, purchase or otherwise acquire (or pay into or set aside
     for a sinking fund for such purpose) any share or shares of Common Stock;
     provided, however, that this restriction shall not apply to the repurchase
     of shares of Common Stock from certain shareholders pursuant to that
     certain Shareholder Agreement dated June 8, 1994 or that certain
     Shareholders' Agreement dated on or about February 12, 1998 or the
     repurchase of shares of Common Stock from employees, officers, directors,
     consultants or other persons performing services for the corporation or any
     subsidiary pursuant to agreements under which the corporation has the
     option to repurchase such shares at cost upon the occurrence of certain
     events, such as the termination of employment; or

          (f) issue, or obligate itself to issue, greater than 533,333 shares of
     Series A Preferred Stock; or

          (g) pay any dividends on the corporation's Common Stock; or


                                      -12-
<PAGE>

          (h) amend the corporation's Articles of Incorporation, provided,
     however, that no such approval shall be required for an amendment to the
     corporation's Articles of Incorporation to increase the total number of
     authorized shares of Common Stock to less than or equal to fifteen million
     (15,000,000) shares; or (i)ab increase the authorized number of directors
     of the corporation to more than thirteen (13).

     9. Status of Redeemed or Converted Stock. In the event (a) any shares of
Series A Preferred Stock shall be redeemed pursuant to Section 5 hereof or (b)
any shares of Series A Preferred Stock shall be converted pursuant to Section 6
hereof, the shares so redeemed or converted shall be cancelled, and such shares
shall not be issuable by the corporation.

     RESOLVED, FURTHER, that the Chairman, President, or any Vice President, and
the Secretary or the Chief Financial Officer of this corporation are hereby
authorized to execute, verify, and file a Certificate of Designation of
Preferences in accordance with Minnesota law.

     C. The authorized number of shares of Preferred Stock of said corporation

     We further declare under penalty of perjury under the laws of the State of
Minnesota that the matters set forth in this Certificate are true and correct of
our own knowledge.

               (h) The term "SEC" means the Securities and Exchange Commission.

          1.2 Request for Registration.

               (a) If the Company shall receive at any time after the earlier of
          (i) February 12, 2001, or (ii) six (6) months after the effective date
          of the first registration statement for a public offering of
          securities of the Company (other than a registration statement
          relating either to the sale of securities to employees of the Company
          pursuant to a stock option, stock purchase or similar plan or a SEC
          Rule 145 transaction), a written request from the Holders of at least
          thirty-five percent (35%) of the Registrable Securities then
          outstanding that the Company file a registration statement under the
          Act covering the registration of Registrable Securities then
          outstanding, the anticipated aggregate offering price of which would
          exceed $10,000,000, then the Company shall:

                    (i) within ten (10) days of the delivery thereof, give
               written notice of such request to all Holders; and

                    (ii) use its best efforts to effect as soon as practicable,
               and in any event within ninety (90) days of the delivery of such
               request, the registration under the Act of all Registrable
               Securities which the Holders request to be registered, subject to
               the limitations of subsection 1.2(b), within twenty (20) days of
               the delivery of such notice by the Company.

               (b) If the Holders initiating the registration request hereunder
          ("Initiating Holders") intend to distribute the Registrable Securities
          covered by their request by means of an underwriting, they shall so
          advise the Company as a part of their request made pursuant to
          subsection 1.2(a) and the Company shall include such information in
          the written notice referred to in subsection 1.2(a). The underwriter
          will be selected by the majority in interest of the Initiating Holders
          and shall be reasonably acceptable to the Company. In such event, the
          right of any Holder to include his Registrable Securities in such
          registration shall be conditioned upon such Holder's participation in
          such underwriting and the inclusion of such Holder's Registrable
          Securities in the underwriting (unless


                                      -2-
<PAGE>

          otherwise mutually agreed by a majority in interest of the Initiating
          Holders and such Holder) to the extent provided herein. All Holders
          proposing to distribute their securities through such underwriting
          shall (together with the Company as provided in subsection 1.4(e))
          enter into an underwriting agreement in customary form with the
          underwriter or underwriters selected for such underwriting.
          Notwithstanding any other provision of this Section 1.2, if the
          underwriter advises the Initiating Holders in writing that marketing
          factors require a limitation of the number of shares to be
          underwritten, then the Initiating Holders shall so advise all Holders
          of Registrable Securities which would otherwise be underwritten
          pursuant thereto, and the number of shares of Registrable Securities
          that may be included in the underwriting shall be allocated among all
          Holders thereof, including the Initiating Holders, in proportion (as
          nearly as practicable) to the amount of Registrable Securities of the
          Company owned by each Holder; provided, however, that the number of
          shares of Registrable Securities to be included in such underwriting
          shall not be reduced unless all other securities are first entirely
          excluded from the underwriting.

               (c) Notwithstanding the foregoing, if the Company shall furnish
          to Holders requesting a registration statement pursuant to this
          Section 1.2, a certificate signed by the President of the Company
          stating that in the good faith judgment of the Board of Directors of
          the Company, it would be seriously detrimental to the Company and its
          shareholders for such registration statement to be filed and it is
          therefore essential to defer the filing of such registration
          statement, the Company shall have the right to defer taking action
          with respect to such filing for a period of not more than ninety (90)
          days after delivery of the request of the Initiating Holders;
          provided, however, that the Company may not utilize this right more
          than once in any twelve-month period.

               (d) In addition, the Company shall not be obligated to effect, or
          to take any action to effect, any registration pursuant to this
          Section 1.2:

                    (i) after the Company has effected two registrations
               pursuant to this Section 1.2 and such registrations have been
               declared or ordered effective;

                    (ii) during the period starting with the date ninety (90)
               days prior to the Company's good faith estimate of the date of
               filing of, and ending on a date one hundred eighty (180) days
               after the effective date of, a registration subject to Section
               1.3 hereof; provided that the Company is actively employing in
               good faith all reasonable efforts to cause such registration
               statement to become effective; or

                    (iii) if the Initiating Holders propose to dispose of shares
               of Registrable Securities that may be immediately registered on
               Form S-3 pursuant to a request made pursuant to Section 1.12
               below.

          1.3 Company Registration. If (but without any obligation to do so) the
     Company proposes to register (including for this purpose a registration
     effected by the Company for shareholders other than the Holders) any of its
     stock or other securities under the Act in connection with the public


                                      -3-
<PAGE>

     offering of such securities solely for cash (other than a registration
     relating solely to the sale of securities to participants in a Company
     stock plan, a registration on any form which does not include substantially
     the same information as would be required to be included in a registration
     statement covering the sale of the Registrable Securities), the Company
     shall, at such time, promptly give each Holder written notice of such
     registration. Upon the written request of each Holder given within twenty
     (20) days after delivery of such notice by the Company, the Company shall,
     subject to the provisions of Section 1.8, cause to be registered under the
     Act all of the Registrable Securities that each such Holder has requested
     to be registered.

          1.4 Obligations of the Company. Whenever required under this Section 1
     to effect the registration of any Registrable Securities, the Company
     shall, as expeditiously as reasonably possible:

               (a) Prepare and file with the SEC a registration statement with
          respect to such Registrable Securities and use its best efforts to
          cause such registration statement to become effective, and, upon the
          request of the Holders of a majority of the Registrable Securities
          registered thereunder, keep such registration statement effective for
          a period of up to one hundred twenty (120) days; provided, however,
          that (i) such 120-day period shall be extended for a period of time
          equal to the period the Holder refrains from selling any securities
          included in such registration at the request of an underwriter of
          Common Stock (or other securities) of the Company; and (ii) in the
          case of any registration of Registrable Securities on Form S-3 which
          are intended to be offered on a continuous or delayed basis, such
          120-day period shall be extended, if necessary, to keep the
          registration statement effective until all such Registrable Securities
          are sold, provided that Rule 415, or any successor rule under the Act,
          permits an offering on a continuous or delayed basis, and provided
          further that applicable rules under the Act governing the obligation
          to file a post-effective amendment permit, in lieu of filing a
          post-effective amendment which (I) includes any prospectus required by
          Section 10(a)(3) of the Act or (II) reflects facts or events
          representing a material or fundamental change in the information set
          forth in the registration statement, the incorporation by reference of
          information required to be included in (I) and (II) above to be
          contained in periodic reports filed pursuant to Section 13 or 15(d) of
          the 1934 Act in the registration statement.

               (b) Prepare and file with the SEC such amendments and supplements
          to such registration statement and the prospectus used in connection
          with such registration statement as may be necessary to comply with
          the provisions of the Act with respect to the disposition of all
          securities covered by such registration statement.

               (c) Furnish to the Holders such numbers of copies of a
          prospectus, including a preliminary prospectus, in conformity with the
          requirements of the Act, and such other documents as they may
          reasonably request in order to facilitate the disposition of
          Registrable Securities owned by them.


                                      -4-
<PAGE>

               (d) Use its best efforts to register and qualify the securities
          covered by such registration statement under such other securities or
          Blue Sky laws of such jurisdictions as shall be reasonably requested
          by the Holders; provided that the Company shall not be required in
          connection therewith or as a condition thereto to qualify to do
          business or to file a general consent to service of process in any
          such states or jurisdictions.

               (e) In the event of any underwritten public offering, enter into
          and perform its obligations under an underwriting agreement, in usual
          and customary form, with the managing underwriter of such offering.
          Each Holder participating in such underwriting shall also enter into
          and perform its obligations under such an agreement.

               (f) Notify each Holder of Registrable Securities covered by such
          registration statement at any time when a prospectus relating thereto
          is required to be delivered under the Act of the happening of any
          event as a result of which the prospectus included in such
          registration statement, as then in effect, includes an untrue
          statement of a material fact or omits to state a material fact
          required to be stated therein or necessary to make the statements
          therein not misleading or incomplete in the light of the circumstances
          then existing, and at the request of any such Holder, prepare and
          furnish to such Holder a reasonable number of copies of a supplement
          to or an amendment of such prospectus as may be necessary so that, as
          thereafter delivered to the purchasers of such shares, such prospectus
          shall not include an untrue statement of a material fact or omit to
          state a material fact required to be stated therein or necessary to
          make the statements therein not misleading or incomplete in the light
          of the circumstances then existing.

               (g) Cause all such Registrable Securities to be listed on each
          securities exchange on which similar securities issued by the Company
          are then listed.

               (h) Provide a transfer agent and registrar and a CUSIP number for
          all such Registrable Securities, in each case not later than the
          effective date of such registration.

               (i) In the event of any underwritten public offering, cooperate
          with the selling Holders, the underwriters participating in the
          offering and their counsel in any due diligence investigation
          reasonably requested by the selling Holders or the underwriters in
          connection therewith, and participate, to the extent reasonably
          requested by the managing underwriter for the offering or the selling
          Holder, in efforts to sell the Registrable Securities under the
          offering (including, without limitation, participating in "roadshow"
          meetings with prospective investors) that would be customary for
          underwritten primary offerings of a comparable amount of equity
          securities by the Company.

          1.5 Furnish Information.

               (a) It shall be a condition precedent to the obligations of the
          Company to take any action pursuant to this Section 1 with respect to
          the Registrable Securities of any selling Holder that such Holder
          shall furnish to the Company such information regarding itself, the
          Registrable


                                      -5-
<PAGE>

          Securities held by it, and the intended method of disposition of such
          securities as shall be required to effect the registration of such
          Holder's Registrable Securities.

               (b) The Company shall have no obligation with respect to any
          registration requested pursuant to Section 1.2 if, due to the
          operation of subsection 1.5(a), the number of shares or the
          anticipated aggregate offering price of the Registrable Securities to
          be included in the registration does not equal or exceed the number of
          shares or the anticipated aggregate offering price required to
          originally trigger the Company's obligation to initiate such
          registration as specified in subsection 1.2(a).

          1.6 Expenses of Demand Registration. All expenses other than
     underwriting discounts and commissions incurred in connection with
     registrations pursuant to Section 1.2, including (without limitation) all
     registration, filing and qualification fees, printers' and accounting fees,
     and fees and disbursements of counsel for the Company (including fees and
     disbursements of one counsel for the selling Holders) shall be borne by the
     Company; provided, however, that the Company shall not be required to pay
     for any expenses of any registration proceeding begun pursuant to Section
     1.2 if the registration request is subsequently withdrawn at the request of
     the Holders of a majority of the Registrable Securities to be registered
     (in which case all participating holders shall bear such expenses), unless
     the Holders of a majority of the Registrable Securities agree to forfeit
     their right to one demand registration pursuant to Section 1.2.

          1.7 Expenses of Company Registration. The Company shall bear and pay
     all expenses incurred in connection with any registration, filing or
     qualification of Registrable Securities with respect to registrations
     pursuant to Section 1.3 for each Holder, including (without limitation) all
     registration, filing, and qualification fees, printers and accounting fees
     relating or apportionable thereto and the fees and disbursements of one
     counsel for the selling Holders, but excluding in all cases underwriting
     discounts and commissions relating to Registrable Securities.

          1.8 Underwriting Requirements. In connection with any offering
     involving an underwriting of shares of the Company's capital stock, the
     Company shall not be required under Section 1.3 to include any of the
     Holders' securities in such underwriting unless they accept the terms of
     the underwriting as agreed upon between the Company and the underwriters
     selected by the Initiating Holders (or by other persons entitled to select
     the underwriters), and then only in such quantity as the underwriters
     determine in their sole discretion will not materially adversely affect the
     success of the offering by the Company. If the total amount of securities,
     including Registrable Securities, requested by shareholders to be included
     in such offering exceeds the amount of securities sold other than by the
     Company that the underwriters determine in their sole discretion is
     compatible with the success of the offering, then the Company shall be
     required to include in the offering only that number of such securities,
     including Registrable Securities, which the underwriters determine in their
     sole discretion will not jeopardize the success of the offering (the
     securities so included to be apportioned pro rata among the selling
     shareholders according to the total amount of securities entitled to be
     included therein owned by each selling Shareholder or in such other
     proportions as shall mutually be agreed to by such selling shareholders)
     but in no event shall (i) the amount of securities of the selling Holders
     included in the


                                      -6-
<PAGE>

     offering be reduced below thirty percent (30%) of the total amount of
     securities included in such offering, unless such offering is the initial
     public offering of the Company's securities in which case the selling
     Holders may be excluded if the underwriters make the determination
     described above and no other shareholder's securities are included or (ii)
     notwithstanding (i) above, any shares being sold by a shareholder
     exercising a demand registration right similar to that granted in Section
     1.2 be excluded from such offering. For purposes of the preceding
     parenthetical concerning apportionment, for any selling shareholder which
     is a holder of Registrable Securities and which is a partnership or
     corporation, the partners, retired partners and shareholders of such
     holder, or the estates and family members of any such partners and retired
     partners and any trusts for the benefit of any of the foregoing persons
     shall be deemed to be a single "selling shareholder," and any pro-rata
     reduction with respect to such "selling shareholder" shall be based upon
     the aggregate amount of shares carrying registration rights owned by all
     entities and individuals included in such "selling shareholder," as defined
     in this sentence.

          1.9 Delay of Registration. No Holder shall have any right to obtain or
     seek an injunction restraining or otherwise delaying any such registration
     as the result of any controversy that might arise with respect to the
     interpretation or implementation of this Section 1.

          1.10 Indemnification. In the event any Registrable Securities are
     included in a registration statement under this Section 1:

               (a) To the extent permitted by law, the Company will indemnify
          and hold harmless each Holder, each of its directors, officers and
          employees, and any underwriter (as defined in the Act) for such Holder
          and each person, if any, who controls such Holder or underwriter
          within the meaning of the Act or the 1934 Act, against any losses,
          claims, damages, or liabilities (joint or several) to which they may
          become subject under the Act, or the 1934 Act, insofar as such losses,
          claims, damages, or liabilities (or actions in respect thereof) arise
          out of or are based upon any of the following statements, omissions or
          violations (collectively a "Violation"): (i) any untrue statement or
          alleged untrue statement of a material fact contained in such
          registration statement, including any preliminary prospectus or final
          prospectus contained therein or any amendments or supplements thereto,
          (ii) the omission or alleged omission to state therein a material fact
          required to be stated therein, or necessary to make the statements
          therein not misleading, or (iii) any violation or alleged violation by
          the Company of the Act, the 1934 Act, or any rule or regulation
          promulgated under the Act, or the 1934 Act; and the Company will,
          promptly upon demand, pay to each such Holder, director, officer,
          employee, underwriter or controlling person any legal or other
          expenses reasonably incurred by them in connection with investigating
          or defending any such loss, claim, damage, liability, or action;
          provided, however, that the indemnity agreement contained in this
          subsection 1.10(a) shall not apply to amounts paid in settlement of
          any such loss, claim, damage, liability, or action if such settlement
          is effected without the consent of the Company (which consent shall
          not be unreasonably withheld), nor shall the Company be liable in any
          such case for any such loss, claim, damage, liability, or action to
          the extent that it arises out of or is based upon a Violation which
          occurs in reliance upon and in conformity with written information
          furnished expressly for use in connection with such registration by
          any such Holder, underwriter or controlling person.


                                      -7-

               (b) To the extent permitted by law, each selling Holder will
          indemnify and hold harmless the Company, each of its directors, each
          of its officers who has signed the registration statement, each
          person, if any, who controls the Company within the meaning of the Act
          or the 1934 Act, any underwriter, any other Holder selling securities
          in such registration statement and any controlling person of any such
          underwriter or other Holder, against any losses, claims, damages, or
          liabilities (joint or several) to which any of the foregoing persons
          may become subject, under the Act or the 1934 Act, insofar as such
          losses, claims, damages, or liabilities (or actions in respect
          thereto) arise out of or are based upon any Violation, in each case to
          the extent (and only to the extent) that such Violation occurs in
          reliance upon and in conformity with written information furnished by
          such Holder expressly for use in connection with such registration;
          and each such Holder will, promptly upon demand, pay any legal or
          other expenses reasonably incurred by any person intended to be
          indemnified pursuant to this subsection 1.10(b), in connection with
          investigating or defending any such loss, claim, damage, liability, or
          action; provided, however, that the indemnity agreement contained in
          this subsection 1.10(b) shall not apply to amounts paid in settlement
          of any such loss, claim, damage, liability or action if such
          settlement is effected without the consent of the Holder, which
          consent shall not be unreasonably withheld; provided, that, in no
          event shall any indemnity under this subsection 1.10(b) exceed the net
          proceeds from the offering received by such Holder.

               (c) Promptly after delivery by an indemnified party under this
          Section 1.10 of notice of the commencement of any action (including
          any governmental action), such indemnified party will, if a claim in
          respect thereof is to be made against any indemnifying party under
          this Section 1.10, deliver to the indemnifying party a written notice
          of the commencement thereof and the indemnifying party shall have the
          right to participate in, and, to the extent the indemnifying party so
          desires, jointly with any other indemnifying party similarly noticed,
          to assume the defense thereof with counsel mutually satisfactory to
          the parties; provided, however, that an indemnified party (together
          with all other indemnified parties which may be represented without
          conflict by one counsel) shall have the right to retain one separate
          counsel, with the reasonable fees and expenses to be paid by the
          indemnifying party, if representation of such indemnified party by the
          counsel retained by the indemnifying party would be inappropriate due
          to actual or potential differing interests between such indemnified
          party and any other party represented by such counsel in such
          proceeding. The failure to deliver written notice to the indemnifying
          party within a reasonable time of the commencement of any such action,
          if prejudicial to its ability to defend such action, shall relieve
          such indemnifying party of any liability to the indemnified party
          under this Section 1.10, but the omission so to deliver written notice
          to the indemnifying party will not relieve it of any liability that it
          may have to any indemnified party otherwise than under this Section
          1.10. Notwithstanding the foregoing, any indemnifying party shall not
          enter into any settlement of any such loss, claim, damage, liability
          or action without the full and complete release of all the indemnified
          parties.

               (d) If the indemnification provided for in this Section 1.10 is
          held by a court of competent jurisdiction to be unavailable to an
          indemnified party with respect to any loss, liability, claim, damage,
          or expense referred to therein, then the indemnifying party, in lieu
          of indemnifying such indemnified party hereunder, shall contribute to
          the amount paid or payable by such indemnified party


                                      -8-
<PAGE>

          as a result of such loss, liability, claim, damage, or expense in such
          proportion as is appropriate to reflect the relative fault of the
          indemnifying party on the one hand and of the indemnified party on the
          other in connection with the statements or omissions that resulted in
          such loss, liability, claim, damage, or expense as well as any other
          relevant equitable considerations. The relative fault of the
          indemnifying party and of the indemnified party shall be determined by
          reference to, among other things, whether the untrue or alleged untrue
          statement of a material fact or the omission to state a material fact
          relates to information supplied by the indemnifying party or by the
          indemnified party and the parties' relative intent, knowledge, access
          to information, and opportunity to correct or prevent such statement
          or omission.

               (e) Notwithstanding the foregoing, to the extent that the
          provisions on indemnification and contribution contained in the
          underwriting agreement entered into in connection with the
          underwritten public offering are in conflict with the foregoing
          provisions, the provisions in the underwriting agreement shall control
          with respect to the rights and obligations of each of the parties to
          such underwriting agreement.

               (f) The obligations of the Company and Holders under this Section
          1.10 shall survive the completion of any offering of Registrable
          Securities in a registration statement under this Section 1, and
          otherwise.

          1.11 Reports Under Securities Exchange Act of 1934. With a view to
     making available to the Holders the benefits of Rule 144 promulgated under
     the Act and any other rule or regulation of the SEC that may at any time
     permit a Holder to sell securities of the Company to the public without
     registration or pursuant to a registration on Form S-3, the Company agrees
     to:

               (a) make and keep public information available, as those terms
          are understood and defined in SEC Rule 144, at all times after ninety
          (90) days after the effective date of the first registration statement
          filed by the Company for the offering of its securities to the general
          public;

               (b) take such action, including the voluntary registration of its
          Common Stock under Section 12 of the 1934 Act, as is necessary to
          enable the Holders to utilize Form S-3 for the sale of their
          Registrable Securities, such action to be taken as soon as practicable
          after the end of the fiscal year in which the first registration
          statement filed by the Company for the offering of its securities to
          the general public is declared effective;

               (c) file with the SEC in a timely manner all reports and other
          documents required of the Company under the Act and the 1934 Act; and

               (d) furnish to any Holder, so long as the Holder owns any
          Registrable Securities, forthwith upon request (i) a written statement
          by the Company that it has complied with the reporting requirements of
          SEC Rule 144 (at any time after ninety (90) days after the effective
          date of the first registration statement filed by the Company), the
          Act and the 1934 Act (at any time after it has


                                      -9-
<PAGE>

          become subject to such reporting requirements), or that it qualifies
          as a registrant whose securities may be resold pursuant to Form S-3
          (at any time after it so qualifies), (ii) a copy of the most recent
          annual or quarterly report of the Company and such other reports and
          documents so filed by the Company, and (iii) such other information as
          may be reasonably requested in availing any Holder of any rule or
          regulation of the SEC which permits the selling of any such securities
          without registration or pursuant to such form.


          1.12 Form S-3 Registration. In case the Company shall receive from a
     Holder a written request or requests that the Company effect a registration
     on Form S-3 with respect to all or a part of the Registrable Securities
     owned by such Holder or Holders, the Company will:

               (a) promptly give written notice of the proposed registration,
          and any related qualification or compliance, to all other Holders; and

               (b) as soon as practicable, effect such registration and all such
          qualifications and compliances as may be so requested and as would
          permit or facilitate the sale and distribution of all or such portion
          of such Holder's or Holders' Registrable Securities as are specified
          in such request, together with all or such portion of the Registrable
          Securities of any other Holder or Holders joining in such request as
          are specified in a written request given within fifteen (15) days
          after delivery of such written notice from the Company; provided,
          however, that the Company shall not be obligated to effect any such
          registration, qualification or compliance, pursuant to this section
          1.12: (i) if Form S-3 is not available for such offering by the
          Holders; (ii) if the Company shall furnish to the Holders a
          certificate signed by the President of the Company stating that in the
          good faith judgment of the Board of Directors of the Company, it would
          be seriously detrimental to the Company and its shareholders for such
          Form S-3 Registration to be effected at such time, in which event the
          Company shall have the right to defer the filing of the Form S-3
          registration statement for a period of not more than ninety (90) days
          after delivery of the request of the Holder or Holders under this
          Section 1.12; provided, however, that the Company shall not utilize
          this right more than once in any twelve month period; (iii) if the
          Company has, within the twelve (12) month period preceding the date of
          such request, already effected two (2) registrations on Form S-3 for
          the Holders pursuant to this Section 1.12; or (iv) in any particular
          jurisdiction in which the Company would be required to qualify to do
          business or to execute a general consent to service of process in
          effecting such registration, qualification or compliance.

               (c) Subject to the foregoing, the Company shall file a
          registration statement covering the Registrable Securities and other
          securities so requested to be registered as soon as practicable after
          delivery of the request or requests of the Holders. All expenses
          incurred in connection with a registration requested pursuant to
          Section 1.12, including (without limitation) all registration, filing,
          qualification, printer's and accounting fees and the reasonable fees
          and disbursements of one counsel for the selling Holder or Holders and
          counsel for the Company, but excluding any underwriters' discounts or
          commissions associated with Registrable Securities, shall be borne by
          the Company. Registrations effected pursuant to this Section 1.12
          shall not be counted as registrations effected pursuant to Sections
          1.2 or 1.3.

          1.13 Assignment of Registration Rights. The rights to cause the
     Company to register Registrable Securities pursuant to this Section 1 may
     be assigned (but only with all related obligations) by a Holder to a
     transferee or assignee of such securities, provided: (a) the Company is,
     within a reasonable time after such transfer, furnished with written notice
     of the name and address of such transferee or assignee and the Registrable
     Securities with respect to which such registration rights are being
     assigned; and (b) such transferee or assignee agrees in writing to be bound
     by and subject to the terms and conditions of this Agreement, including
     without limitation the provisions of Section 1.15 below.

          1.14 Limitations on Subsequent Registration Rights. From and after the
     date of this Agreement, the Company shall not, without the prior written
     consent of the Holders of a majority of the outstanding Registrable
     Securities, enter into any agreement with any holder or prospective holder
     of any securities of the Company which would allow such holder or
     prospective holder (a) to include such securities in any registration filed
     under Section 1.2 hereof, unless under the terms of such agreement, such
     holder or prospective holder may include such securities in any such
     registration only to the extent that the inclusion of his securities will
     not reduce the amount of the Registrable Securities of the Holders which is
     included or (b) to make a demand registration which could result in such
     registration statement being declared effective prior to the earlier of
     either of the dates set forth in subsection 1.2(a) or within one hundred
     eighty (180) days of the effective date of any registration effected
     pursuant to Section 1.2.

          1.15 "Market Stand-Off" Agreement. Each Investor hereby agrees that,
     during the period of duration specified by the Company and an underwriter
     of Common Stock or other securities of the Company, following the effective
     date of a registration statement of the Company filed under the Act, it
     shall not, to the extent requested by the Company and such underwriter,
     directly or indirectly sell, offer to sell, contract to sell (including,
     without limitation, any short sale), grant any option to purchase or
     otherwise transfer or dispose of (other than to donees who agree to be
     similarly bound) any securities of the Company held by it at any time
     during such period except Common Stock included in such registration;
     provided, however, that:

               (a) such agreement shall not exceed one hundred eighty (180) days
          for the first such registration statement of the Company which covers
          Common Stock (or other securities) to be sold on its behalf to the
          public in an underwritten offering;

               (b) such agreement shall not exceed ninety (90) days for any
          subsequent registration statement of the Company which covers Common
          Stock (or other securities) to be sold on its behalf to the public in
          an underwritten offering; and

               (c) an Investor shall not be subject to such agreement unless all
          executive officers and directors of the Company enter into similar
          agreements and all other Investors and holders of other registration
          rights are subject to or obligated to enter into similar agreements.


                                      -11-
<PAGE>

          In order to enforce the foregoing covenant, the Company may impose
     stop-transfer instructions with respect to the Registrable Securities of
     each Investor (and the shares or securities of every other person subject
     to the foregoing restriction) until the end of such period.

          1.16 Termination of Registration Rights. No Holder shall be entitled
     to exercise any right provided for in this Section 1 after the earlier of
     (i) five (5) years following the consummation of the sale of securities
     pursuant to a registration statement filed by the Company under the Act in
     connection with the initial firm commitment underwritten offering of its
     securities to the general public (the "IPO") and (ii) that date following
     the IPO upon which each Holder holds less than 1% of the then issued and
     outstanding shares of capital stock of the Company and such shares may be
     immediately sold under Rule 144 during any 90 day period.

     2. Covenants of the Company.

          2.1 Delivery of Financial Statements. The Company shall deliver to
     each Investor:

               (a) as soon as practicable, but in any event within ninety (90)
          days after the end of each fiscal year of the Company, an income
          statement for such fiscal year, a balance sheet of the Company and
          statement of shareholder's equity as of the end of such year, and a
          schedule as to the sources and applications of funds for such year,
          such year-end financial reports to be in reasonable detail, prepared
          in accordance with generally accepted accounting principles ("GAAP"),
          and audited and certified by independent public accountants of
          nationally recognized standing selected by the Company;

               (b) as soon as practicable, but in any event within forty-five
          (45) days after the end of each of the first three (3) quarters of
          each fiscal year of the Company, an unaudited profit or loss
          statement, schedule as to the sources and application of funds for
          such fiscal quarter and an unaudited balance sheet as of the end of
          such fiscal quarter;

               (c) within thirty (30) days of the end of each month, an
          unaudited income statement and schedule as to the sources and
          application of funds and unaudited balance sheet for and as of the end
          of such month, in reasonable detail;

               (d) as soon as practicable, but in any event thirty (30) days
          prior to the end of each fiscal year, a budget and business plan for
          the next fiscal year, prepared on a monthly basis, including balance
          sheets and sources and applications of funds statements for such
          months and, as soon as prepared, any other budgets or revised budgets
          prepared by the Company;

               (e) with respect to the financial statements called for in
          subsections (b) and (c) of this Section 2.1, an instrument executed by
          the Chief Financial Officer or President of the Company and certifying
          that such financial statements were prepared in accordance with GAAP
          consistently applied with prior practice for earlier periods (with the
          exception of footnotes that may be


                                      -12-
<PAGE>

          required by GAAP) and fairly present the financial condition of the
          Company and its results of operation for the period specified, subject
          to year-end audit adjustment;

               (f) such other information relating to the financial condition,
          business, prospects or corporate affairs of the Company as the
          Investor or any assignee of the Investor may from time to time
          request, provided, however, that the Company shall not be obligated
          under this subsection (f) or any other subsection of Section 2.1 to
          provide information which it deems in good faith to be a trade secret
          or similar confidential information.

          2.2 Inspection. The Company shall permit each Investor, at such
     Investor's expense, to visit and inspect the Company's properties, to
     examine its books of account and records and to discuss the Company's
     affairs, finances and accounts with its officers, all at such reasonable
     times and during normal working hours as may be requested by the Investor;
     provided, however, that the Company shall not be obligated pursuant to this
     Section 2.2 to provide access to any information which it reasonably
     considers to be a trade secret or similar confidential information.

          2.3 Termination of Information, Inspection and First Offer Covenants.
     The covenants set forth in Sections 2.1, 2.2 and 2.4 shall terminate and be
     of no further force or effect upon the IPO or when the Company first
     becomes subject to the periodic reporting requirements of Sections 12(g) or
     15(d) of the 1934 Act, whichever event shall first occur.

          2.4 Right of First Offer. Subject to the terms and conditions
     specified in this Section 2.4, the Company hereby grants to each Investor a
     right of first offer with respect to future sales by the Company of its
     Shares (as hereinafter defined). For purposes of this Section 2.4, Investor
     includes any general partners and affiliates of an Investor. An Investor
     shall be entitled to apportion the right of first offer hereby granted it
     among itself and its partners and affiliates in such proportions as it
     deems appropriate.

          Each time the Company proposes to offer any shares of, or securities
     convertible into or exercisable for any shares of, any class of its capital
     stock ("Shares"), the Company shall first make an offering of such Shares
     to each Investor in accordance with the following provisions:

               (a) The Company shall deliver a notice by certified mail
          ("Notice") to the Investors stating (i) its bona fide intention to
          offer such Shares, (ii) the number of such Shares to be offered, and
          (iii) the price and terms, if any, upon which it proposes to offer
          such Shares.

               (b) Within twenty (20) calendar days after delivery of the
          Notice, the Investor may elect to purchase or obtain, at the price and
          on the terms specified in the Notice, up to that portion of such
          Shares which equals the proportion that the number of shares of Common
          Stock issued and held, or issuable upon conversion of the Series A
          Preferred Stock then held, by such Investor bears to the total number
          of shares of Common Stock of the Company then outstanding (assuming
          full conversion and exercise of all convertible or exercisable
          securities).


                                      -13-
<PAGE>

               (c) If all Shares which Investors are entitled to obtain pursuant
          to subsection 2.4(b) are not elected to be obtained as provided in
          subsection 2.4(b) hereof, the Company may, during the 30-day period
          following the expiration of the period provided in subsection 2.4(b)
          hereof, offer the remaining unsubscribed portion of such Shares to any
          person or persons at a price not less than, and upon terms no more
          favorable to the offeree than, those specified in the Notice. If the
          Company does not enter into an agreement for the sale of the Shares
          within such period, or if such agreement is not consummated within
          thirty (30) days of the execution thereof, the right provided
          hereunder shall be deemed to be revived and such Shares shall not be
          offered unless first reoffered to the Investors in accordance
          herewith.


               (d) The right of first offer in this Section 2.4 shall not be
          applicable to the issuance or sale of (i) securities issued pursuant
          to the exercise or conversion of exercisable or convertible
          securities; (ii) securities issued pursuant to the terms of any joint
          venture agreement or in an acquisition of the business of any other
          corporation, or other business entity, by way of merger,
          reorganization, transfer of assets or consolidation (or any similar

          and are not convertible into capital stock of the Company; (iv) Common

          best interests of the Company and its shareholders; (vii) securities

          recapitalization of the Company; and (viii) any right, option or

                             SHAREHOLDERS' AGREEMENT


     THIS SHAREHOLDERS' AGREEMENT is made as of the 12th day of February 1998,
by and among PEMSTAR Inc., a Minnesota corporation (the "Company"), the holders
of Common Stock of the Company listed on the attached Schedule A (individually,
a "Common Holder" and collectively, the "Common Holders"), and the holders of
Series A Preferred Stock of the Company listed on the attached Schedule B
(individually, a "Preferred Holder" and collectively, the "Preferred Holders").

                                    RECITALS
                                    --------

     A. Pursuant to that certain Series A Stock Purchase Agreement dated as of
the date hereof among the Company and the Preferred Holders, the Preferred
Holders are purchasing or agreeing to purchase an aggregate of 533,333 shares of
the Company's Series A Preferred Stock (the "Series A Financing").

     C. In order to induce the Preferred Holders to purchase the Series A
Preferred Stock, the Common Holders desire to grant to the Company and the
Preferred Holders rights of first refusal and co-sale with respect to the Common
Holders' shares of Common Stock of the Company.

     NOW, THEREFORE, in consideration of the mutual covenants set forth herein,
the parties agree as follows:

     1. Definitions.

          a. "Common Stock" shall mean the Company's Common Stock and shares of
     Common Stock issued or issuable upon conversion of the Company's
     outstanding Preferred Stock.

          b. "Preferred Stock" shall mean the Company's Series A Preferred Stock
     now owned or subsequently acquired by the Preferred Holders.

          c. "Stock" shall mean shares of the Company's Common Stock now owned
     or subsequently acquired by the Common Holders.

          d. "Transfer" shall mean any direct or indirect sale, exchange,
     transfer, assignment, pledge, creation of a security interest in, or
     encumbrance on, or other disposition by a Common Holder of all or any
     portion of such Common Holder's interest in the Common Stock or any
     economic interest therein (including without limitation by means of any
     participation or swap transaction).
<PAGE>

     2. Right of First Refusal.

          a. Notice to the Company and Preferred Holders.

               (i) In the event any Common Holder (the "Transferring
          Shareholder") desires to Transfer any Stock other than as specifically
          provided in Section 5 below, such Transferring Shareholder must
          deliver a notice in writing by certified mail ("Notice") to the
          Company stating (A) his bona fide intention to Transfer such shares,
          (B) the number of such shares to be Transferred, (C) the price, if
          any, for which he proposes to Transfer such shares, and (D) the name
          of the proposed purchaser or transferee.

               (ii) In the event the proposed Transfer is partially or
          completely in exchange for assets other than cash, then such assets
          shall be deemed to have a cash value in the amount determined by the
          Company's Board of Directors in its sole good faith opinion, in which
          case such cash value ascertained by the Board, when added to any cash
          to be exchanged and then divided by the number of shares of Stock to
          be Transferred, shall be deemed the price per share set forth in the
          Notice. In the event of a gift, property settlement or other Transfer
          in which the proposed purchaser or transferee is not paying the full
          price for the Stock, which Transfer is not otherwise exempted from the
          terms of Section 2 and 3 hereof, the price shall be deemed to be the
          fair market value of the Stock as determined in good faith by the
          Board of Directors.

          b. Company Right of First Refusal. The Company shall have an
     exclusive, irrevocable option (the "Company Option"), at any time within
     twenty (20) days of receipt of the Notice, to purchase all (but not less
     than all) of the Stock to which the Notice refers at the price per share
     specified in the Notice (as determined in Section 2(a)(ii)). The Company
     shall exercise the Company Option by written notice signed by an officer of
     the Company and delivered or mailed to the Transferring Shareholder (the
     "Company Settlement Notice"), which notice shall specify the time, place
     and date for settlement of such purchase.

          c. Company Settlement. Within ten (10) days of receipt of the Company
     Settlement Notice, the Transferring Shareholder must deliver to the Company
     all certificates for the Stock being acquired by the Company, together with
     proper assignments in blank of the Stock with signatures properly
     guaranteed and with such other documents as may be required by the Company
     to provide reasonable assurance that each necessary endorsement is genuine
     and effective, and the Company must thereupon deliver to the Transferring
     Shareholder full cash payment for the Stock being acquired, provided that
     if the terms of payment set forth in the Notice were other than cash
     against delivery, the Company shall pay for said shares on the same terms
     and conditions set forth in such Notice.

          d. Preferred Holders' Right of First Refusal. In the event that the
     Company does not exercise the Company Option, the Company shall, not later
     than twenty (20) days from the date of


                                      -2-
<PAGE>

     receipt of the Notice, give written notice to the Preferred Holders of the
     Company's nonexercise of the Company Option, which notice shall enclose the
     Notice and shall specify the procedures by which each Preferred Holder may
     exercise the option to purchase not more than its Pro Rata Share (as
     defined in Section 2(g) below) of the Stock to which the Notice refers (the
     "Preferred Holder Option"). For twenty (20) calendar days following the
     expiration of the Company Option, each Preferred Holder may exercise its
     Preferred Holder Option at the same price and upon the same terms as set
     forth in the Notice. Any Preferred Holder desiring to exercise its
     Preferred Holder Option shall deliver to the Company and to the
     Transferring Shareholder a written notice of election to purchase the
     shares with respect to which the Preferred Holder Option is to be
     exercised.

          e. Assignment of Preferred Holder Option. Each Preferred Holder may
     assign its rights under this Section 2 to (i) any of its limited partners
     or shareholders, (ii) any entity related to or affiliated with such
     Preferred Holder, or (iii) another Preferred Holder; provided, however,
     that if payment is to be made in any manner other than all cash against
     delivery of the Stock being sold, such assignee must be at least as
     creditworthy as the Preferred Holder so assigning its rights or the payment
     for the Stock must be guaranteed by the Preferred Holder so assigning its
     rights, and provided, further, however, that the issuance of such shares of
     Stock to the assignee shall be exempt from registration.

          f. Preferred Holder Settlement. Promptly upon expiration of the
     Preferred Holder Option, the Company shall deliver a notice in writing to
     the Transferring Shareholder and each Preferred Holder and/or assignee who
     elected to acquire a portion of the Stock subject to the Preferred Holder
     Option (the "Preferred Holder Settlement Notice") setting forth the number
     of shares of Stock to be sold to each Preferred Holder and/or assignee and
     the price thereof. Within ten (10) days of receipt of the Preferred Holder
     Settlement Notice, the Transferring Shareholder must deliver to the Company
     any certificates for the Stock being acquired by the Preferred Holders
     and/or assignees, together with proper assignments in blank of the Stock
     with signatures properly guaranteed and with such other documents as may be
     required by the Company to provide reasonable assurance that each necessary
     endorsement is genuine and effective. Within ten (10) days of receipt of
     the Preferred Holder Settlement Notice, each Preferred Holder and/or
     assignee acquiring a portion of the Stock must deliver to the Company full
     cash payment for the portion of the subject Stock being so acquired,
     provided that if the terms of payment set forth in the Notice were other
     than cash against delivery, the Preferred Holders electing to acquire a
     portion of the subject Stock and/or their assignees shall pay for said
     shares on the same terms and conditions set forth in such Notice. The
     Company shall thereafter promptly remit full payment for the Stock acquired
     hereby to the Transferring Shareholder and deliver the new or assigned
     certificates to the Preferred Holders and/or assignees, as appropriate.

          g. Determination of Pro Rata Share. For purposes of Section 2 above,
     each Preferred Holder's "Pro Rata Share" is the ratio of (i) the total
     number of shares of Common Stock and Preferred Stock held by such Preferred
     Holder as of the date of the Notice (on an as-converted to Common Stock
     basis) to (ii) the total aggregate shares of Common Stock and Preferred
     Stock held by


                                      -3-
<PAGE>

     all Preferred Holders as of such date that have elected to exercise the
     Preferred Holder Option (on an as-converted to Common Stock basis).


     3. Co-Sale Rights.

          a. Notice to Preferred Holders. In the event that less than all of the
     shares of Stock proposed to be Transferred by a Transferring Shareholder
     are acquired by the Company and/or Preferred Holders (or their assignees)
     pursuant to the Company Option and/or the Preferred Holder Option set forth
     in Section 2 above (collectively, the "Options"), the Company shall
     deliver, promptly upon expiration of the Options, a notice in writing to
     each Preferred Holder (the "Co-Sale Notice") reiterating the names of the
     prospective purchaser, a transferee, the number of shares of Stock proposed
     to be Transferred and not acquired pursuant to the Options, and the price
     per share at which such shares are proposed to be Transferred.

          b. Rights of Co-Sale. Each Preferred Holder shall have the right,
     exercisable upon written notice to the Transferring Shareholder within ten
     (10) days after receipt of the Co- Sale Notice, to participate in such sale
     of Stock on the same terms and conditions. To the extent one or more of the
     Preferred Holders exercise such right of participation in accordance with
     the terms and conditions set forth below, the number of shares of Stock
     that the Transferring Shareholder may sell in the transaction shall be
     correspondingly reduced.

          c. Determination of Participation Right. Each Preferred Holder may
     sell all or any part of that number of shares of Preferred Stock or Common
     Stock equal to the product obtained by multiplying (i) the aggregate number
     of shares of Stock covered by the Co-Sale Notice by (ii) a fraction the
     numerator of which is the number of shares of Common Stock owned by or
     issuable upon conversion of the shares of Preferred Stock owned by such
     Preferred Holder at the time of the Transfer and the denominator of which
     is the total number of shares of Common Stock owned by the Transferring
     Shareholder plus the number of shares of Common Stock owned by or issuable
     upon conversion of the shares of Preferred Stock owned by all of the
     Preferred Holders at the time of the Transfer.

          d. Rights of Participating Preferred Holders. If any Preferred Holder
     fails to elect to fully participate in such Transferring Shareholder's sale
     pursuant to this Section 3, the Transferring Shareholder shall give notice
     of such failure to the Preferred Holders who did so elect (the
     "Participating Preferred Holders"). Such notice may be made by telephone if
     confirmed in writing within two (2) days. The Participating Preferred
     Holders shall have the right, exercisable upon written notice to the
     Transferring Shareholder within five (5) days from the date such notice was
     given, to sell additional shares of Common Stock or Preferred Stock equal
     to their pro rata share of the unsold portion. For purposes of this Section
     3(d), a Participating Preferred Holder's pro rata share of the unsold
     portion shall be the ratio of (x) the number of shares of Common Stock held
     by or issuable upon conversion of the shares of Preferred Stock held by
     such Participating Preferred Holder to (y) the total


                                      -4-
<PAGE>

     number of shares of Common Stock held by or issuable upon conversion of the
     shares of Preferred Stock held by all of the Participating Preferred
     Holders plus the number of shares of Common Stock held by the Transferring
     Shareholder.

          e. Delivery of Shares. Each Participating Preferred Holder shall
     effect its participation in the sale by promptly delivering to the
     Transferring Shareholder for transfer to the prospective purchaser or
     transferee one or more certificates, properly endorsed for transfer, which
     represent:

               (i) the type and number of shares of Common Stock which such
          Participating Preferred Holder elects to sell; or

               (ii) that number of shares of Preferred Stock which is at such
          time convertible into the number of shares of Common Stock which such
          Participating Preferred Holder elects to sell; provided, however, that
          if the prospective purchaser or transferee objects to the delivery of
          Preferred Stock in lieu of Common Stock, such Participating Preferred
          Holder shall convert such Preferred Stock into Common Stock and
          deliver Common Stock as provided in Section 3(e)(i) above. The Company
          agrees to make any such conversion concurrent with the actual transfer
          of such shares to the purchaser or transferee.

          f. Settlement. The stock certificate or certificates that the
     Participating Preferred Holder delivers to the Transferring Shareholder
     pursuant to Section 2(e) shall be transferred to the prospective purchaser
     or transferee in consummation of the sale of the Stock pursuant to the
     terms and conditions specified in the Co-Sale Notice, and the Transferring
     Shareholder shall concurrently therewith remit to such Participating
     Preferred Holder that portion of the sale proceeds to which such
     Participating Preferred Holder is entitled by reason of its participation
     in such sale. To the extent that any prospective purchaser or transferee
     prohibits such assignment or otherwise refuses to purchase shares or other
     securities from a Participating Preferred Holder exercising its rights of
     co-sale hereunder, the Transferring Shareholder shall not sell to such
     prospective purchaser or transferee any Stock unless and until,
     simultaneously with such sale, the Transferring Shareholder shall purchase
     such shares or other securities from such Participating Preferred Holder.

          g. No Prejudice from Non-Exercise. The exercise or non-exercise of the
     rights of the Preferred Holders hereunder to participate in one or more
     sales of Stock made by the Transferring Shareholder shall not adversely
     affect their rights to participate in subsequent sales of Stock subject to
     this Section 3.

     4. Additional Rights of Preferred Holders.

          a. Prohibited Transfers. In the event a Common Holder should sell any
     Stock in contravention of the co-sale rights of the Preferred Holders under
     Section 3 (a "Prohibited Transfer"),


                                      -5-
<PAGE>

     the Preferred Holders, in addition to such other remedies as may be
     available at law, in equity or hereunder, shall have the put option
     provided below, and the Common Holder shall be bound by the applicable
     provisions of such option.

          b. Grant of Put Option. In the event of a Prohibited Transfer, each
     Preferred Holder shall have the right to sell to the Common Holder the type
     and number of shares of Stock equal to the number of shares each Preferred
     Holder would have been entitled to transfer to the purchaser or transferee
     had the Prohibited Transfer been effected pursuant to and in compliance
     with the terms of Section 3 above (the "Put Option"). Such sale shall be
     made on the following terms and conditions:

               (i) The price per share at which the shares are to be sold to the
          Common Holder shall be equal to the price per share paid by the
          purchaser or transferee to the Common Holder in the Prohibited
          Transfer. The Common Holder shall also reimburse each Preferred Holder
          for any and all reasonable fees and expenses, including reasonable
          legal fees and expenses, incurred pursuant to the exercise of the Put
          Option.

               (ii) Within forty-five (45) days after the later of the dates on
          which the Preferred Holder (A) received notice of the Prohibited
          Transfer or (B) otherwise becomes aware of the Prohibited Transfer,
          each Preferred Holder shall, if exercising the Put Option, deliver to
          the Common Holder a notice exercising the Put Option (the "Put Option
          Notice").

               (iii) Immediately upon receipt of the Put Option Notice, the
          Common Holder shall make available the aggregate purchase price
          therefor and the amount of reimbursable fees and expenses, as
          specified in Section 4(b)(i), in cash or by other means acceptable to
          the Preferred Holder. The Preferred Holder shall concurrently make
          available to the Common Holder the certificate or certificates
          representing the shares to be sold, each properly endorsed for
          transfer.

          c. Prohibited Transfers Void. Notwithstanding the foregoing, any
     attempt by a Common Holder to Transfer Stock in violation of Sections 2 or
     3 hereof, whether voluntarily or involuntarily, shall be void and the
     Company agrees it will use its reasonable best efforts to not effect such a
     Transfer or treat any alleged transferee as the holder of such Stock.

     5. Exempt Transfers.

          a. Transfers to Affiliates. Notwithstanding the rights of first
     refusal and co-sale rights set forth in Sections 2 and 3 of this
     Agreement, a Common Holder may Transfer all or any part of the Stock owned
     by such Common Holder:

               (i) in the case of individuals, (A) to members of his or her
          Immediate Family if by gift, where "Immediate Family" means any
          parent, spouse, child, grandchild, brother or


                                      -6-
<PAGE>

          sister of the Common Holder or any trust for the sole benefit of any
          or all of such persons, and (B) to his or her heirs, executors or
          other fiduciaries pursuant to a last will and testament; and

               (ii) in the case of any other Common Holder, (A) to its
          Affiliates, where "Affiliates" means any other person or entity that,
          directly or indirectly, through one or more intermediaries, is in
          control of, is controlled by, or is under common control with such
          Common Holder, and (B) to its successors in interest.

          b. De Minimus Transfers. Notwithstanding the Preferred Holders'
     co-sale rights set forth in Section 3 of this Agreement, each Common Holder
     may Transfer up to a cumulative total of twenty-five thousand (25,000)
     shares of Stock (subject to appropriate adjustment for stock splits, stock
     dividends, combinations and other recapitalizations) owned by such Common
     Holder free of the Preferred Holders' co-sale rights.

          c. Prior Agreement. Notwithstanding the rights of first refusal and
     co-sale rights set forth in Sections 2 and 3 of this Agreement, a Common
     Holder, if a party thereto, may Transfer all or any part of the Stock owned
     by such Common Holder to the Company or certain other shareholders of the
     Company pursuant to the terms of that certain Shareholder Agreement dated
     June 4, 1994 (the "Prior Agreement"), provided, however, that if any of the
     shares of Stock to be Transferred by a Common Holder to a third party is
     not purchased by the Company or the other shareholders pursuant to the
     terms of the Prior Agreement, then such shares shall remain subject to the
     Preferred Holder Option.

          d. Conditions to Exempt Transfers. Any Transfer of Stock made pursuant
     to the provisions of Section 5.a. or 5.c. above shall be subject to the
     following:

               (i) Prior to the completion of such Transfer, each such
          transferee or such transferee's legal representative shall have
          executed documents in form and substance satisfactory to the Company,
          evidenced by the Company's written acknowledgement of such
          satisfaction, assuming the obligations of a Common Holder under this
          Agreement with respect to the transferred Stock; and

               (ii) Such transferred Stock shall remain subject to the
          provisions of this Agreement, and the transferee shall be treated as a
          "Common Holder" for purposes of this Agreement.

     6. Termination of Restrictions on Transfers. The rights of first refusal
and the co-sale rights under Sections 2 and 3 of this Agreement shall terminate
upon the occurrence of any one of the following events: (a) the liquidation,
dissolution or indefinite cessation of the business operations of the Company;
(b) the execution by the Company of a general assignment for the benefit of
creditors or the appointment of a receiver or trustee to take possession of all
or substantially all of the property and assets of the Company; or (c) upon the
effective date of a bona fide firm commitment underwritten public offering of
the Company's Common Stock registered under the Securities Act of 1933, as


                                      -7-
<PAGE>

amended, on Form S-1 (or any successor form designated by the Securities and
Exchange Commission).

     7. Agreement to Vote for Series A Nominee.

          a. For so long as 250,000 shares (subject to appropriate adjustment
     for stock splits, stock dividends, combinations and other
     recapitalizations) of the Company's Series A Preferred Stock (and/or the
     Common Stock issuable upon conversion thereof) are held by any of the
     Preferred Holders, the Common Holders agree to vote all shares of Common
     Stock now or hereafter owned by them to elect to the Company's board of
     directors a nominee of the majority of the Preferred Holders (the "Series A
     Nominee").

          b. Prior to each election of directors of the Company, the majority of
     the Preferred Holders shall designate the Series A Nominee in writing to
     the Company. The Company shall promptly notify each of the Common Holders
     of such nominee. Any vacancy occurring because of the death, resignation,
     removal or disqualification of the Series A Nominee shall be filled
     according to this Section 7.

          c. The Company and the Common Holders agree to use their best efforts
     to ensure that the rights given to the Preferred Holders pursuant to this
     Section 7 are effective and that the such holders shall enjoy the benefits
     hereof. Such best efforts shall include, without limitation, the use of the
     Company's and the Common Holders' best efforts to cause the Series A
     Nominee to be elected as a director of the Company at each election of the
     board of directors. Neither the Company nor the Common Holders shall, by
     any voluntary action, avoid or seek to avoid the observance or performance
     of any of the terms to be performed hereunder, but shall at all times in
     good faith assist in the carrying out of all of the provisions of this
     Section 7, and shall use their best efforts to protect the rights of the
     Preferred Holders against impairment.

     8. Legends; Stop Transfer Instructions.

          a. Legends. Each certificate representing shares of Stock now or
     hereafter owned by the Common Holders or issued to any person in connection
     with a Transfer pursuant to Section 5 hereof shall be endorsed with the
     following legend:

         "THE SALE, PLEDGE, HYPOTHECATION, TRANSFER OR VOTING OF THE SHARES
         REPRESENTED BY THIS CERTIFICATE IS RESTRICTED BY AND SUBJECT TO THE
         PROVISIONS OF A SHAREHOLDERS' AGREEMENT, AS THE SAME MAY BE AMENDED
         FROM TIME TO TIME, AMONG THE PARTIES NAMED THEREIN, A COPY OF WHICH IS
         AVAILABLE AT THE PRINCIPAL OFFICE OF THE ISSUER OF SUCH SHARES."


                                      -8-
<PAGE>

          b. Stop Transfer Instructions. Each Common Holder agrees that the
     Company may instruct its transfer agent to impose transfer restrictions on
     the shares represented by certificates bearing the legend referred to in
     Section 8(a) above to enforce the provisions of this Agreement and the
     Company agrees to promptly do so. The legend shall be removed upon
     termination of this Agreement.

     9. "Market Stand-off" Agreement. Each Common Holder hereby agrees that,
during the period of duration specified by the Company and an underwriter of
Common Stock or other securities of the Company, following the effective date of
a registration statement of the Company filed under the Act, it shall not, to
the extent requested by the Company and such underwriter, directly or indirectly
sell, offer to sell, contract to sell (including, without limitation,
any short sale), grant any option to purchase or otherwise Transfer or dispose
of (other than to donees who agree to be similarly bound) any securities of the
Company held by it at any time during such period except Common Stock included
in such registration; provided, however, that:

          a. such agreement shall not exceed one hundred eighty (180) days for
     the first such registration statement of the Company which covers Common
     Stock (or other securities) to be sold on its behalf to the public in an
     underwritten offering; and

          b. such agreement shall not exceed ninety (90) days for any subsequent
     registration statement of the Company which covers Common Stock (or other
     securities) to be sold on its behalf to the public in an underwritten
     offering.

     In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to the Stock of each Common Holder (and
the shares or securities of every other person subject to the foregoing
restriction) until the end of such period.

     10. Additional Issuances of Common Stock. The Company agrees that, except
for Common Stock issued pursuant to any arrangement approved by the Board of
Directors to employees, officers and directors of, or consultants, advisors or
other persons performing services for, the Company, it shall not issue any
additional shares of Common Stock or Preferred Stock after the date hereof until
the issuee of such shares agrees to become a party to this Agreement as a Common
Holder and has executed a counterpart signature page to this Agreement provided,
however, that if a Preferred Holder purchases additional shares of Common or
Preferred Stock after the date hereof, then the Company shall not require such
Preferred Holder to become a party to this Agreement as a Common Holder. Except
as provided for in the immediately preceding sentence, any issuance of Common
Stock or Preferred Stock without the issuee becoming a party hereto shall be
void until such issuee has agreed to be bound by the terms hereof and has signed
a counterpart signature page to this Agreement.

     11. Miscellaneous.

          a. Conditions to Exercise of Rights. Exercise of the rights granted to
     the Company and the Preferred Holders under this Agreement shall be subject
     to and conditioned upon, and the parties shall use their best efforts to
     assist the Company and the Preferred Holders in, compliance with applicable
     laws.

          b. Corporate Law Compliance. The right of the Company to repurchase
     any of the Stock is subject to the restrictions governing the rights of a
     corporation to purchase its own shares contained in the Minnesota Business
     Corporation Act and such other pertinent governmental restrictions as may
     from time to time be effective.

          c. Governing Law. This Agreement shall be governed by and construed
     under the laws of the State of New York as applied to agreements among New
     York residents entered into and to be performed entirely within New York.

          d. Amendment. Any provision of this Agreement may be amended and the
     observance thereof may be waived (either generally or in a particular
     instance and either retroactively or prospectively), only by the written
     consent of (i) as to the Company, only by the Company, (ii) as to the
     Preferred Holders, by persons holding more than fifty percent (50%) in
     interest of the Preferred Stock and Common Stock issuable upon the
     conversion thereof then held by the Preferred Holders and their assignees
     pursuant to Section 11(e) hereof, and (iii) as to the Common Holders, by
     persons holding more than fifty percent (50%) in interest of the Common
     Stock then held by the Common Holders; provided, however, that the
     amendment or waiver of any provision of this Agreement that affects a
     Common Holder in a manner that is adverse to such Common Holder and does
     not similarly affect all other Common Holders shall require the written
     consent of such Common Holder; provided further, that any Preferred Holder
     may individually waive any of his rights hereunder without obtaining the
     consent of any other Preferred Holder. Any amendment or waiver effected in
     accordance with this Section shall be binding upon the Company, each Common
     Holder, each Preferred Holder and their successors and permitted assigns,
     even if the Common Holder, Preferred Holder or their successors and
     permitted assigns has not executed such amendment or waiver.
     Notwithstanding the foregoing, any waiver by a Preferred Holder, or the
     Preferred Holders, as to any one Common Holder or as to any one transaction
     shall not waive any of the Preferred Holders' rights as to any other Common
     Holder or as to any other transaction.

          e. Assignment of Rights. This Agreement and the rights and obligations
     of the parties hereunder shall inure to benefit of, and be binding upon,
     their respective successors, permitted assigns and legal representatives.

          f. Term. This Agreement shall terminate upon the earlier of (i) the
     closing of a firm commitment underwritten public offering of shares of the
     Company's capital stock pursuant to a registration statement on Form S-1
     under the Securities Act of 1933, as amended, or (ii) the closing of the
     Company's sale of all or substantially all of its assets or the acquisition
     of the Company by another


                                      -10-
<PAGE>

     entity by means of merger or consolidation resulting in the exchange of the
     outstanding shares of the Company's capital stock for securities or
     consideration issued, or caused to be issued, by the acquiring entity or
     its subsidiary.

          g. Power of Attorney. Each Common Holder and Preferred Holder, by
     executing this Agreement, irrevocably appoints each of the officers of the
     Company his, her or its true and lawful attorney-in-fact to execute any
     amendments hereto for the sole purpose of adding or deleting Common Holders
     or Preferred Holders.

          h. Entire Agreement. This Agreement constitutes the entire agreement
     among the parties and no party shall be liable or bound to any other party
     in any manner by any warranties, representations, or covenants except as
     specifically set forth herein.

          i. Notices. Unless otherwise provided, any notice required or
     permitted under this Agreement shall be given in writing and shall be
     deemed effectively given upon (a) personal delivery to the party to be
     notified, (b) upon telefacsimile transmission to the party to be notified
     at the telefacsimile number indicated for such party on the signature page
     hereof, if any, or (c) upon deposit with an overnight courier service or
     the United States Post Office, by registered or certified mail, postage
     prepaid and addressed to the party to be notified at the address(es)
     indicated for such party on the signature page hereof, or at such other
     address as such party may designate by ten (10) days' advance written
     notice to the other parties. Notwithstanding the foregoing, the telephone
     notice permitted by Section 3(d) shall be effective at the time it is given
     if confirmed in writing within two (2) days.

          j. Additional Parties to Agreement. Any individuals and/or entities
     that hold any shares of the Common Stock of the Company shall be entitled
     to become a party to this Agreement, and the addition of such individuals
     and/or entities as parties to this Agreement and any required amendment of
     Schedule A in connection therewith shall not be considered an amendment of
     this Agreement requiring the consent of the Common Holders or the Preferred
     Holders. Upon execution of a counterpart signature page to this Agreement
     by any of such individuals and/or entities, such individuals and/or
     entities shall become parties to this Agreement to the same extent as if
     they had executed this Agreement as of the date hereof and shall be
     included in the definition of "Common Holders" under this Agreement for all
     purposes. Schedule A to this Agreement shall be automatically amended as
     appropriate to reflect the addition of such individuals and/or entities as
     Common Holders under this Agreement.

          k. Ownership. Each Common Holder represents and warrants that he is
     the sole legal and beneficial owner of the shares of Stock subject to this
     Agreement and that no other person has any interest (other than a community
     property interest) in such shares.


                                      -11-
<PAGE>

          l. Severability. If one or more provisions of this Agreement are held
     to be unenforceable under applicable law, such provision shall be excluded
     from this Agreement and the balance of the Agreement shall be interpreted
     as if such provision were so excluded and shall be enforceable in
     accordance with its terms.

          m. Attorneys' Fees. In the event that any dispute among the parties to
     this Agreement should result in litigation, the prevailing party in such
     dispute shall be entitled to recover from the losing party all reasonable
     fees, costs and expenses of enforcing any right of such prevailing party
     under or with respect to this Agreement, including without limitation, such
     reasonable fees and expenses of attorneys and accountants, which shall
     include, without limitation, all fees, costs and expenses of appeals.

          n. Titles and Subtitles. The titles and subtitles used in this
     Agreement are used for convenience only and are not to be considered in
     construing or interpreting this Agreement.

          o. Counterparts. This Agreement may be executed in one or more
     counterparts, each of which shall be deemed an original, but all of which
     together shall constitute one and the same instrument.

          p. Shares Bound by this Agreement. The parties executing this
     Agreement as a Common Holder agree that such party is bound by the
     obligations of a Common Holder hereunder with regard to any and all shares
     of Common Stock of the Company held by such party in such party's sole
     name, in joint tenancy, as a trustee or a co-trustee, or in any form of
     beneficial ownership (as defined in Rule 13d-3 promulgated by the
     Securities and Exchange Commission under the Securities Exchange Act of
     1934).
