(61st) day after the expiration of the Commitment Period (as defined in that
Equity Line of Credit Agreement dated November 21, 2000 between the Company
and H&QGF, as amended (the "Equity Agreement") unless (a) the number of
shares of Registrable Securities issuable to H&QGF upon exercise of the
Warrant and any prior warrant issued to H&QGF (assuming conversion of the
Class of Stock into Common Stock), together with (b) the Put Shares which the
Company is then entitled to Put (as such terms are defined in the Equity
Agreement) (assuming conversion of such Put Shares into Registrable
Securities) would not exceed the limitation set forth in Section 7.2(h) of
the Equity Line of Credit Agreement.

          3. EXERCISE OF WARRANT; PAYMENT; ISSUANCE OF NEW WARRANT.

                   3.1 Subject to Section 2 hereof, the purchase rights
         represented by this Warrant may be exercised by the Holder, in whole or
         in part, by the surrender of this Warrant (with the notice of exercise
         form attached hereto as Appendix A duly executed) at the principal
         office of the Company and by the payment to the Company, by check made
         payable to the Company drawn on a United States bank and for United
         States dollars, or by wire transfer to an account of the Company, of an
         amount equal to the then applicable Warrant Price per share multiplied
         by the number of Shares then being purchased. In the event of any
         exercise of the purchase right described in this Section 3, a
         certificate(s) for the Shares so purchased shall be delivered to the
         Holder within thirty (30) days of receipt of such payment and, unless
         this Warrant has been fully exercised or expired, a new Warrant (dated
         as of the date hereof) representing the

<PAGE>

         portion of the Shares, if any, with respect to which this Warrant
         shall not then have been exercised shall also be issued to the
         Holder within such thirty (30) day period. All shares of the Class of
         Stock, Common Stock or other securities issued upon the exercise of
         this Warrant shall be validly issued, fully paid and nonassessable,
         and the Company will pay all taxes in respect of the issuance thereof
         (other than any transfer tax or any income or capital gain taxes

follows:

                  The securities evidenced by this certificate have not been
registered under the Securities Act of 1933, as amended, or applicable state
securities laws and rules. No sale, offer to sell or transfer of the
securities represented by this certificate shall be made unless a
registration statement under such act, and applicable state securities laws
with respect to such securities is then in effect, or pursuant to an
exemption from such registration requirements for such laws as may then be in
effect, or an opinion of counsel reasonably satisfactory to Company and its
counsel that such registration is not required.

4. ADJUSTMENT OF NUMBER AND KIND OF SHARES AND ADJUSTMENT OF WARRANT PRICE.

                  4.1 CERTAIN DEFINITIONS: As used in this Section 4, the
following  terms shall have the respective meanings:

                  (a) OPTIONS: rights, options or warrants to subscribe for,
         purchase or otherwise  acquire shares of Common Stock or Convertible
         Securities.

                  (b) CONVERTIBLE SECURITIES: any evidence of indebtedness,
         shares  of  stock  or  other securities directly or indirectly
         convertible into or exchangeable for Common Stock.

                  4.2 ADJUSTMENTS: The number and kind of securities
purchasable upon the exercise of this Warrant and the Warrant Price shall be
subject to adjustment from time to time upon the occurrence of certain
events, as follows:

                   (a) RECLASSIFICATION, REORGANIZATION, CONSOLIDATION OR
         MERGER. In the case of any reclassification of the Common Stock, or any
         reorganization, consolidation or merger of the Company with or into
         another corporation (other than a merger or reorganization with respect
         to which the Company is the continuing corporation and which does not
         result in any

                                     Page 3
<PAGE>

         reclassification of the Common Stock) (a "Reclassification"), the
         Company, or such successor corporation, as the case may be, shall
         execute a new warrant providing that the Holder shall have the right
         to exercise such new warrant and upon such exercise to receive, in
         lieu of each share of the Class of Stock theretofore issuable upon
         exercise of this Warrant, the number and kind of securities
         receivable upon such reclassification, reorganization, consolidation
         or merger by a holder of shares of the Class of Stock for each such
         share of the Class of Stock. The aggregate Warrant Price of the new
         warrant shall be the aggregate Warrant Price in effect immediately
         prior to the Reclassification, and the Warrant Price per share shall
         be appropriately increased or decreased. Such new warrant shall
         provide for adjustments which shall be as nearly equivalent as may be
         practicable to the adjustments provided for in this Section 4
         including, without limitation, adjustments to the Warrant Price and to
         the number of shares issuable upon exercise of this Warrant. The
         provisions of this subsection (a) shall similarly apply to successive
         Reclassifications.

                   (b) SPLIT, SUBDIVISION OR COMBINATION OF SHARES. If the
         Company at any time while this Warrant remains outstanding; and
         unexpired shall split, subdivide or combine the Class of Stock for
         which this Warrant is then exercisable, the Warrant Price shall be
         proportionately decreased in the case of a split or subdivision or
         proportionately increased in the case of a combination. Any adjustment
         under this subsection (b) shall become effective when the split,
         subdivision or combination becomes effective.

                   (c) STOCK DIVIDENDS. If the Company at any time while this
         Warrant remains outstanding and unexpired shall pay a dividend with
         respect to the Class of Stock for which this Warrant is then
         exercisable, payable in shares of that Class of Stock, Options, or
         Convertible Securities, the Warrant Price shall be adjusted, from and
         after the date of determination of the shareholders entitled to receive
         such dividend or distributions, to that price determined by multiplying
         the Warrant Price in effect immediately prior to such date of
         determination by a fraction (i) the numerator of which shall be the
         total number of shares of that Class of Stock outstanding immediately
         prior to such dividend or distribution, and (ii) the denominator of
         which shall be the total number of shares of the same Class of Stock
         outstanding immediately after such dividend or distribution (including
         shares of that Class of Stock issuable upon exercise, conversion or
         exchange of any Option or Convertible Securities issued as such
         dividend or distribution). If the Options or Convertible Securities
         issued as such dividend or distribution by their terms provide, with
         the passage of time or otherwise, for any decrease in the consideration
         payable to the Company, or any increase in the number of shares
         issuable upon exercise, conversion or exchange thereof (by change of
         rate or otherwise), the Warrant Price shall, upon any such decrease or
         increase becoming effective, be reduced to reflect such decrease or

                                    Page 4
<PAGE>

         increase as if such decrease or increase became effective immediately
         prior to the issuance of the Options or Convertible Securities as the
         dividend or distribution. Any adjustment under this subsection (c)
         shall become effective on the record date.

                  (d) OTHER SECURITIES. In the event the Company at any time or
         from time to time after the issuance of this Warrant makes, or fixes a
         record date for the determination of holders of Common Stock entitled
         to receive, a dividend or other distribution payable in securities of
         the Company other than shares of Common Stock, then, and in each such
         event, provision shall be made so that the Holder shall receive, upon
         exercise hereof, in addition to the number of shares of Common Stock
         receivable thereupon, the amount of securities of the Company which the
         Holder would have received had this Warrant been exercised (assuming
         conversion of the Class of Stock into Common Stock) on the date of such
         event and had the Holder thereafter, during the period from the date of
         such event to and including the date of exercise, retained such
         securities receivable by such Holder as aforesaid during such period,
         subject to all other adjustments called for during such period under
         this Section 4 with respect to the rights of the Holder.

                  (e) NEW SECURITIES. If the Company, at any time while this
         Warrant remains outstanding and unexpired, shall issue additional
         shares of Common Stock, Options or Convertible Securities at a price
         per share below the Warrant Price (except for (i) issuances under the
         Equity Agreement, and (ii) grants of awards of options or restricted
         stock to employees or consultants of the Company approved by the
         Company's Board of Directors pursuant to an equity incentive or similar
         plan, and (iii) issuances of up to and including $1,000,000 under the
         Reichmann Transaction as defined in the First Amendment to Equity Line
         of Credit Agreement dated as of even date herewith, the Warrant Price
         shall be reduced to such price. Notwithstanding the foregoing, the
         Company shall not be required to make any adjustment to the Warrant
         Price in the case of the issuance of shares of Common Stock, Options or
         Convertible Securities upon the exercise of any options or warrants
         outstanding as of the Date of Grant.

                  4.3 ADJUSTMENT OF NUMBER OF SHARES. Upon each adjustment in
the Warrant Price pursuant to Section 4.2 hereof, the number of Shares
issuable upon exercise of this Warrant shall be adjusted to the product
obtained by multiplying the number of Shares issuable immediately prior to
such adjustment in the Warrant Price by a fraction (a) the numerator of which
shall be the Warrant Price immediately prior to such adjustment, and (b) the
denominator of which shall be the Warrant Price immediately after such
adjustment.

                                   Page 5
<PAGE>

         5. NOTICE OF ADJUSTMENTS. Whenever the Warrant Price shall be
adjusted pursuant to Section 4 hereof, the Company shall issue a certificate
signed by its chief financial officer or chief executive officer setting
forth, in reasonable detail, the event requiring the adjustment, the amount
of the adjustment, the method by which such adjustment was calculated and the
Warrant Price after giving effect to such adjustment and shall cause a copy
of such certificate to be mailed (by first class mail, postage prepaid) to
the Holder.

         6. RIGHT TO CONVERT WARRANT INTO STOCK.

                  6.1 CONVERSION PRICE. The conversion price ("Conversion
Price") of one share of the Class of Stock for which this Warrant is then
exercisable is determined as, for the three months prior to any conversion of
the Warrant into such Class of Stock:

                  (a) if the Common Stock is publicly traded, the product of (a)
         the highest closing sale price or, if no closing sale price is
         reported, the highest daily average between the ask and bid prices of
         the Common Stock quoted on any exchange or over-the-counter market on
         which the Common Stock is listed, whichever is applicable, as published
         in the Western Edition of THE WALL STREET JOURNAL, and (b) the number
         of shares of Common Stock into which each share of the Class of Stock
         for which this Warrant is then exercisable is then convertible, if
         applicable; or,

                  (b) if the Common Stock is not traded in an over-the-counter
         market or on an exchange, the highest fair market value of a single
         share of the Class of Stock for which this Warrant is then exercisable,
         as determined in good faith by the Company's Board of Directors'
         provided; however, that if the Holder disputes in writing the fair
         market value determined by the Board of Directors within thirty (30)
         days of being informed of such fair market value, the fair market value
         shall be determined by an independent appraiser, appointed in good
         faith by the Company's Board of Directors.

                  6.2 RIGHT TO CONVERT. In addition to the rights granted
under Section 3 of this Warrant, the Holder shall have the right to require
the Company to convert this Warrant (the "Conversion Right") into shares of
the Class of Stock for which the Warrant is then exercisable, as provided in
this Section 6. Upon exercise of the Conversion Right, the Company shall
deliver to the Holder (without payment by the Holder of any Warrant Price)
that number of shares of stock equal to the quotient obtained by dividing (x)
the value of this Warrant at the time of the Conversion Right is exercised
(determined by subtracting the aggregate Warrant Price immediately prior to
the exercise of the Conversion Right from the aggregate Conversion Price) by
(y) the Conversion Price.

                                  Page 6
<PAGE>

                  6.3 METHOD OF EXERCISE. The Conversion Right may be
exercised at any time by the Holder by the surrender of this Warrant at the
principal office of the Company together with a written statement specifying
that the Holder thereby intends to exercise the Conversion Right.
Certificates evidencing the Shares issuable exercise of the Conversion Right
shall be delivered to the Holder within thirty (30) days following
determination of the Conversion Price.

                  6.4 AUTOMATIC CONVERSION PRIOR TO EXPIRATION. To the extent
this Warrant is not previously exercised, and if the Conversion Price is
greater than the Warrant Price per share on the expiration date, this Warrant
shall be deemed automatically exercised in accordance with Section 6.2 hereof
(even if not surrendered) immediately before its expiration. To the extent
this Warrant or any portion thereof is deemed automatically exercised
pursuant to this Section 6.4, the Company agrees to notify Holder within a
reasonable period of time of the number of shares of the Class of Stock, if
any, Holder is to receive by reason of such automatic exercise. The Company
shall issue to the Holder certificates for the Shares issued upon such
automatic conversion in accordance with Section 6.3 above, although the
Company may condition receipt of the certificate upon surrender of the
Warrant to the Company.

         7. TRANSFERABILITY AND NON-NEGOTIABILITY OF WARRANTS AND SHARES.
This Warrant and the Shares issued upon exercise hereof may not be
transferred or assigned in whole or in part without compliance with
applicable federal and state securities laws by the transferor and the
transferee (including, without limitation, the delivery of investment
representation letters and legal opinions reasonably satisfactory to the
Company, if reasonably requested by the Company). Subject to the provisions
