      This Warrant certificate ("WARRANT CERTIFICATE") certifies that, for value
received, _____________________________________ is the registered holder of the
number of warrants (the "WARRANTS") set forth above. Each Warrant entitles the
holder thereof, at any time or from time to time during the Exercise Period, to

      "PRICE" means (a) the average of the "high" and "low" prices for the
Common Stock as reported in The Wall Street Journal's listing for such day
(corrected for obvious typographical errors), or if such shares are not reported
in such listing, the average of the reported sales prices on the largest
national securities exchange (based on the aggregate dollar value of securities
listed) on which such shares are listed or traded; (b) if the Common Stock is
not then listed or admitted to trading on any national securities exchange, but
is designated as a Small Cap Market system security, the last trading price of
the Common Stock on such date; or (c) if such shares are not listed or traded on
any national securities exchange or the Nasdaq Small Cap Market, then the
average of the reported sales prices for such shares in the over-the-counter
market, as reported on the National Association of Securities Dealers Automated
Quotations System, or, if such prices shall not be reported thereon, the average
of the closing bid and asked prices so reported, or, if such prices shall not be
reported, then the average of the closing bid and asked prices reported by the

      "NOTE AND WARRANT PURCHASE AGREEMENT" means the Note and Warrant Purchase
Agreement, dated as of September 8, 2004, between the Company and the Investors.

      SECTION 1.  EXERCISE OF WARRANTS.

            (a)   The Warrants may be exercised in whole or in part, at any time
      or from time to time, during the Exercise Period, by presentation and
      surrender to the Company at its address set forth in SECTION 8 of this
      Warrant Certificate (or the delivery of a customary affidavit of loss with
      indemnity) with the Election To Exercise, attached hereto as EXHIBIT A
      duly completed and executed, and (i) payment in full of the Exercise
      Price, for the number of Warrants being exercised by wire transfer in
      immediately available funds, bank draft or cashier's check, or (ii)
      without payment of any additional consideration through a "cashless" or
      "net-issue" exercise of each such Warrant ("Cashless Exercise"); in a
      Cashless Exercise, the holder shall exchange each Warrant subject to a
      Cashless Exercise for that number of Warrant Shares determined by
      multiplying the number of Warrant Shares issuable hereunder by a fraction,
      the numerator of which shall be the difference between (x) the Price (for
      the trading day preceding such presentation and surrender), and (y) the
      Exercise Price for each such Warrant, and the denominator of which shall
      be the Price (for the trading day preceding such presentation and
      surrender); and the Election to Exercise shall set forth the calculation
      upon which the Cashless Exercise is based, or (iii) a combination of (i)
      and (ii) above. If the holder of this Warrant Certificate at any time
      exercises less than all the Warrants, the Company shall issue to such a
      holder a warrant certificate identical in form to this Warrant
      Certificate, but evidencing a number of Warrants equal to the number of
      Warrants originally represented by this Warrant Certificate less the
      number of Warrants previously exercised. Likewise, upon the presentation
      and surrender of this Warrant Certificate to the Company at its address
      set forth in SECTION 8 and at the request of the holder, the Company will,
      without expense, at the option of the holder, issue to the holder in
      substitution for this Warrant Certificate one or more warrant certificates
      in identical form and for an aggregate number of Warrants equal to the
      number of Warrants evidenced by this Warrant Certificate.

                                       2
<PAGE>

            (b)   To the extent that the Warrants have not been exercised at or
      prior to the Expiration Date, such Warrants shall expire and the rights of
      the holder shall become void and of no effect.

            (c)   Upon surrender of this Warrant Certificate in conformity with
      the foregoing provisions, the Company shall transfer to the holder of this
      Warrant Certificate appropriate evidence of ownership of the shares of
      Common Stock or other securities or property (including any money) to
      which the holder is entitled, registered or otherwise placed in, or
      payable to the order of, the name or names of the holder or such
      transferee as may be directed in writing by the holder, and shall deliver
      such evidence of ownership and any other securities or property (including
      any money) to the Person or Persons entitled to receive the same, together
      with an amount in cash in lieu of any fraction of a share.

            (d)   The Company shall not be required to issue a fractional share
      of Common Stock upon the exercise of Warrants. As to any fraction of a
      share which the Warrant holder would otherwise be entitled to purchase
      upon such exercise, the Company may pay a cash adjustment in respect of
      such fraction in an amount equal to the same fraction of the Price per
      share of Common Stock on the date of exercise.

      SECTION 2.  ANTIDILUTION ADJUSTMENTS. The shares of Common Stock
purchasable on exercise of the Warrants are shares of Common Stock as
constituted as of the Issuance Date. The number and kind of securities
purchasable upon the exercise of the Warrants, and the Exercise Price, shall be
subject to adjustment from time to time upon the happening of certain events, as
follows:

            (a)   Mergers, Consolidations and Reclassifications. In case of any
      reclassification or change of outstanding securities issuable upon
      exercise of the Warrants at any time after the Issuance Date (other than a
      change in par value, or from par value to no par value, or from no par
      value to par value or as a result of a subdivision or combination to which
      SECTION 2(b) applies), or in case of any consolidation or merger of the
      Company with or into any entity or other person (other than a merger with
      another entity or other person in which the Company is the surviving
      corporation and which does not result in any reclassification or change in
      the securities issuable upon exercise of this Warrant Certificate), the
      holder of the Warrants shall have, and the Company, or such successor
      corporation or other entity, shall covenant in the constituent documents
      effecting any of the foregoing transactions that such holder does have the
      right to obtain, upon the exercise of the Warrants, in lieu of each share
      of Common Stock, other securities, money or other property theretofore
      issuable upon exercise of a Warrant, the kind and amount of shares of
      stock, other securities, money or other property receivable upon such
      reclassification, change, consolidation or merger by a holder of the
      shares of Common Stock, other securities, money or other property issuable
      upon exercise of a Warrant if the Warrants had been exercised immediately
      prior to such reclassification, change, consolidation or merger. The
      constituent documents effecting any such reclassification, change,
      consolidation or merger shall provide for adjustments, which shall be as
      nearly equivalent as may be practicable to the adjustments provided in
      this
                                       3
<PAGE>

SECTION 2(a). The provisions of this SECTION 2(a) shall similarly apply to
successive reclassifications, changes, consolidations or mergers.

            (b)   Subdivisions and Combinations. If the Company, at any time
      after the Issuance Date, shall subdivide its shares of Common Stock into a
      greater number of shares, the Exercise Price in effect immediately prior
      to such subdivision shall be proportionately reduced, and the number of
      shares of Common Stock purchasable upon exercise of the Warrants shall be
      proportionately increased, as at the effective date of such subdivision,
      or if the Company shall take a record of holders of its Common Stock for
      such purpose, as at such record date, whichever is earlier. If the
      Company, at any time after the Issuance Date, shall combine its shares of
      Common Stock into a smaller number of shares, the Exercise Price in effect
      immediately prior to such combination shall be proportionately increased,
      and the number of shares of Common Stock purchasable upon exercise of the
      Warrants shall be proportionately reduced, as at the effective date of
      such combination, or if the Company shall take a record of holders of its
      Common Stock for purposes of such combination, as at such record date,
      whichever is earlier.

            (c)   Dividends and Distributions. If the Company at any time after
      the Issuance Date shall declare a dividend on its Common Stock payable in
      stock or other securities of the Company to the holders of its Common
      Stock, the holder of this Warrant Certificate shall, without additional
      cost, be entitled to receive upon any exercise of a Warrant, in addition
      to the Common Stock to which such holder would otherwise be entitled upon
      such exercise, the number of shares of stock or other securities which
      such holder would have been entitled to receive if he had been a holder
      immediately prior to the record date for such dividend (or, if no record
      date shall have been established, the payment date for such dividend) of
      the number of shares of Common Stock purchasable on exercise of such
      Warrant immediately prior to such record date or payment date, as the case
      may be.

            (d)   Adjustments of Exercise Price. This SECTION 2(d) shall govern
      adjustments to the Exercise Price for the transactions described herein.

                  (i)   If (x) the Company at any time after the Issuance Date
            and prior to the expiration of eighteen months after the Issuance
            Date shall issue any additional shares of Common Stock (otherwise
            than as provided in subsections (a) through (c) of SECTION 2;
            pursuant to any Employee Benefit Plan (defined below); or pursuant
            to any security or evidence of indebtedness which is convertible
            into or exchangeable for Common Stock ("CONVERTIBLE SECURITY") or
            any warrant, option or other right to subscribe for or purchase
            common stock or any Convertible Security, other than pursuant to
            Employee Benefit Plans, (together with Convertible Securities
            hereinafter referred to as "COMMON STOCK EQUIVALENT") outstanding as
            of the Issuance Date) or upon the issuance of any such Common Stock,
            any adjustments shall previously have been made pursuant to SECTION
            2(d)(ii), and (y) the New Stock Issuance Price (defined below) of
            such additional shares is less than the Exercise Price then in
            effect, then the Exercise Price upon each such issuance shall be
            adjusted to the New Stock Issuance Price of such additional shares.
            The "New Stock Issuance Price" shall be determined by

                                       4
<PAGE>

            dividing the total amount of consideration received by the Company
            for such issue or sale by the number of shares of Common Stock
            issued or sold.

                  (ii)  If the Company at any time after the Issuance Date and
            prior to the expiration of eighteen months after the Issuance Date,
            issues any Common Stock Equivalent (otherwise than as provided in
            subsections (a) through (c) of SECTION 2; or pursuant to any Common
            Stock Equivalent outstanding as of the Issuance Date) and the New
            CSE Exercise Price (defined below) of such Common Stock Equivalents
            is less than the Exercise Price then in effect, then the Exercise
            Price upon each such issuance shall be adjusted to the New CSE
            Exercise Price of such Common Stock Equivalents. The "New CSE
            Exercise Price" shall be determined by dividing (x) the total
            amount, if any, received or receivable by the Company as
            consideration for the issuance of such Common Stock Equivalents,
            plus the minimum aggregate amount of additional consideration
            payable to the Company upon the exercise, conversion or exchange of
            such Common Stock Equivalents, plus, in the case of any such Common
            Stock Equivalents which relate to Convertible Securities, the
            minimum aggregate amount of additional consideration, if any,
            payable to the Company upon the conversion or exchange of such
            Convertible Securities, by (y) the total maximum number of shares of
            Common Stock issuable upon the exercise, conversion or exchange of
            all such Common Stock Equivalents.

      No adjustments of the Exercise Price shall be made under this SECTION 2(d)
      upon the issuance of any additional shares of Common Stock that (w) are
      issued pursuant to any grant or award made prior to the Issuance Date
      under any thrift plan, stock purchase plan, stock bonus plan, stock option
      plan, employee stock ownership plan, incentive or profit sharing
      arrangement or other benefit or compensation plan for the benefit of the
      Company's officers, directors and/or employees ("EMPLOYEE BENEFIT PLANS")
      that has been approved by the Board of Directors of the Company or its
      compensation committee and that otherwise would cause an adjustment under
      this SECTION 2(d); (x) are issued pursuant to any grant or award made on
      or after the Issuance Date under any Employee Benefit Plan if the
      "Exercise Price" of any such issuance is not less than the lesser of the
      Exercise Price as determined above and the "Fair Market Value," as defined
      under the applicable Employee Benefit Plan, on the date of Board or
      compensation committee authorization; (y) are issued pursuant to any
      Common Stock Equivalent (as hereinafter defined) if such Common Stock
      Equivalent was issued prior to this Warrant Certificate; or (z) are issued
      pursuant to a public offering by the Company.

            (e)   Miscellaneous. The following provisions shall be applicable to
      the making of adjustments in the Exercise Price hereinbefore provided in
      this SECTION 2.

                  (i)   The consideration received by the Company shall be
            deemed to be the following: (x) to the extent that any additional
            shares of Common Stock or any Common Stock Equivalent shall be
            issued for cash consideration, the consideration received by the
            Company therefor, or, if such additional shares of Common

                                       5
<PAGE>

            Stock or Common Stock Equivalent are offered by the Company for
            subscription, the subscription price, or, if such additional shares
            of Common Stock or Common Stock Equivalent are sold to underwriters
            or dealers for public offering without a subscription offering, the
            public offering price, in any such case excluding any amounts paid
            or receivable for accrued interest or accrued dividends and without
            deduction of any compensation, discounts, commissions or expenses
            paid or incurred by the Company for and in the underwriting of, or
            otherwise in connection with, the issue thereof; and (y) to the
            extent that such issuance shall be for a consideration other than
            cash, then, except as herein otherwise expressly provided, the fair
            value of such consideration at the time of such issuance as
            determined in good faith by the Board of Directors, as evidenced by
            a certified resolution of the Board of Directors delivered to the
            holder of this Warrant Certificate setting forth such determination.
            The consideration for any additional shares of Common Stock issuable
            pursuant to any Common Stock Equivalent shall be the consideration
            received by the Company for issuing such Common Stock Equivalent,
            plus the additional consideration payable to the Company upon the
            exercise, conversion or exchange of such Common Stock Equivalent. In
            case of the issuance at any time of any additional shares of Common
            Stock or Common Stock Equivalent in payment or satisfaction of any
            dividend upon any class of stock other than Common Stock, the
            Company shall be deemed to have received for such additional shares
            of Common Stock or Common Stock Equivalent (which shall not be
            deemed to be a dividend payable in, or other distribution of, Common
            Stock under SECTION 2(c)consideration equal to the amount of such
            dividend so paid or satisfied. In the event additional shares of
            Common Stock or Common Stock Equivalents are issued together with
            other shares or securities or other assets of the Company or its
            subsidiaries for consideration which covers both, the consideration
            for such shares of Common Stock and Common Stock Equivalents shall
            be computed based on the respective portions of such consideration
            so received, computed as provided in this SECTION 2(e)(i) as
            determined and allocated in good faith by the Board of Directors of
            the Company.

                  (ii)  Upon the expiration of the right to convert, exchange or
            exercise any Common Stock Equivalent the issuance of which effected
            an adjustment in the Exercise Price, if any such Common Stock
            Equivalent shall not have been converted, exercised or exchanged,
            the number of shares of Common Stock deemed to be issued and
            outstanding because they were issuable upon conversion, exchange or
            exercise of any such Common Stock Equivalent shall no longer be
            computed as set forth above, and the Exercise Price shall forthwith
            be readjusted and thereafter be the price which it would have been
            (but reflecting any other adjustments in the Exercise Price made
            pursuant to the provisions of SECTION 2(d) after the issuance of
            such Common Stock Equivalent) had the adjustment of the Exercise
            Price made upon the issuance or sale of such Common Stock Equivalent
            been made on the basis of the issuance only of the number of
            additional shares of Common Stock actually issued upon exercise,
            conversion or exchange of such Common Stock Equivalent and thereupon
            only the number of additional shares of Common Stock actually so
            issued shall be deemed to have been issued and only the
            consideration actually received by the Company (computed as in this
            SECTION 2(e)(i)) shall be deemed to have been received by the
            Company.

                                       6
<PAGE>

                  (iii) The number of shares of Common Stock at any time
            outstanding shall not include any shares thereof then directly or
            indirectly owned or held by or for the account of the Company or its
            wholly owned subsidiaries.

                  (iv)  Upon each adjustment of the Exercise Price as a result
            of the calculations made in SECTION 2(d), hereof, this Warrant shall
            thereafter evidence the right to purchase, at the adjusted Exercise
            Price, the number of shares of Common Stock obtained by (x)
            multiplying the number of shares covered by this Warrant immediately
            prior to such adjustment of the number of shares by the Exercise
            Price in effect immediately prior to such adjustment of the Exercise
            Price, and (y) dividing the product so obtained by the Exercise
            Price in effect immediately after such adjustment of the Exercise
            Price.

                  (v)   For the purpose of this SECTION 2 the term "shares of
            Common Stock" shall mean shares of (x) the class of stock designated
            as the Common Stock at the date hereof, or (y) any other class of
            stock resulting from successive changes or reclassifications of such
            shares consisting solely of changes in par value, or from par value
            to no par value, or from no par value to par value. If at any time,
            because of an adjustment pursuant to SECTION 2(a), the Warrants
            shall entitle the holders to purchase any securities other than
            shares of Common Stock, thereafter the number of such other
            securities so purchasable upon exercise of each Warrant and the
            Exercise Price of such securities shall be subject to adjustment
            from time to time in a manner and on terms as nearly equivalent as
            practicable to the provisions with respect to the Common Stock
            contained in this SECTION 2.

            (f)   Calculation of Exercise Price. The Exercise Price in effect
      from time to time shall be calculated to four decimal places and rounded
      to the nearest thousandth.

            (g)   NASDAQ Matters. Notwithstanding anything to the contrary
      herein, any adjustment to the Exercise Price that would require
      stockholder approval pursuant to the NASDAQ Market Rules shall be subject
      to the Company's obtaining such requisite approval.

      SECTION 3.  NOTICE OF ADJUSTMENTS. Whenever the Exercise Price or the
number of shares of Common Stock is required to be adjusted as provided in
SECTION 2, the Company shall forthwith compute the adjusted Exercise Price or
the number of shares of Common Stock issuable and shall prepare and mail to the
holder hereof a certificate setting forth such adjusted Exercise Price or such
number of shares of Common Stock, showing in reasonable detail the facts upon
which the adjustment is based.

      SECTION 4.  NOTICES TO WARRANT HOLDERS. In the event:

            (a)   the Company authorizes any consolidation or merger to which
      the Company is a party and for which approval of any stockholders of the
      Company is required, or the conveyance or sale of all or substantially all
      of the assets of the Company, or any reclassification or change of the
      Common Stock or other securities

                                       7
<PAGE>

      issuable upon exercise of the Warrants (other than a change in par value,
      or from par value to no par value, or from no par value to par value or as
      result of a subdivision or combination), or a tender offer or exchange
      offer for shares of Common Stock (or other securities issuable upon the
      exercise of the Warrants); or

            (b)   the Company declares any dividend (or any other distribution)
      on the Common Stock or any other class of its capital stock; or

            (c)   the Company authorizes the granting to the holders of Common
      Stock or any other class of its capital stock of rights or warrants to
      subscribe for or purchase any shares of any class or series of capital
      stock or any other securities convertible into or exchangeable for shares
      of stock; or

            (d)   of the voluntary or involuntary dissolution, liquidation or
      winding up of the Company; then the Company shall cause to be sent to the
      holder hereof, at least 30 days prior to the applicable record date
      hereinafter specified, or promptly in the case of events for which there
      is no record date, a written notice stating (x) the date for the
      determination of the holders of record of shares of Common Stock (or other
      securities issuable upon the exercise of the Warrants) entitled to receive
      any such dividends or other distribution, (y) the initial expiration date
      set forth in any tender offer or exchange offer for shares of Common Stock
      (or other securities issuable upon the exercise of the Warrants), or (z)
      the date on which any of the events specified in subsections (a)-(d) is
      expected to become effective or consummated, and the date as of which it
      is expected that holders of record of shares of Common Stock (or other
      securities issuable upon the exercise of the Warrants) shall be entitled
      to exchange such shares for securities or other property, if any,
      deliverable upon any such event. Failure to give such notice or any defect
      therein shall not affect the legality or validity of any such event, or
      the vote upon any such action.

      SECTION 5.  REPORTS TO WARRANT HOLDERS. The Company will cause to be
delivered, by first-class mail, postage prepaid, to holder at such holder's
address appearing hereon, or such other address as the holder shall specify, a
copy of any reports delivered by the Company to the holders of Common Stock.

      SECTION 6.  COVENANTS OF THE COMPANY. The Company covenants and agrees
that:

            (a)   Until the Expiration Date, the Company shall at all times
      reserve and keep available, out of the aggregate of its authorized but
      unissued Common Stock (and other securities), for the purpose of enabling
      it to satisfy any obligation to issue shares of Common Stock (and other
      securities) upon the exercise of the Warrants, the number of shares of
      Common Stock (and other securities) issuable upon the exercise of such
      Warrants.

            (b)   The Company shall pay all expenses, taxes and other charges
      payable in connection with the preparation, issuance and delivery of new
      warrant certificates on transfer of the Warrants.

                                        8
<PAGE>

            (c)   All Common Stock (and other securities) which may be issued
      upon exercise of the Warrants shall upon issuance be validly issued, fully
      paid, non-assessable and free from all preemptive rights and all taxes,
      liens and charges with respect to the issuance thereof, and will not be
      subject to any restrictions on voting or transfer thereof except as set
      forth in the Note and Warrant Purchase Agreement, any stockholders
      agreement and except for restrictions arising under state or federal
      securities laws.

            (d)   All original issue taxes payable in respect of the issuance of
      shares of Common Stock to the registered holder hereof upon the exercise
      of the Warrants shall be borne by the Company; provided, however, that the
      Company shall not be required to pay any tax or charge imposed in
      connection with any transfer involved in the issuance of any certificates
      representing shares of Common Stock (and other securities) in any name
      other than that of the registered holder hereof, and in such case the
      Company shall not be required to issue or deliver any certificate
      representing shares of Common Stock (and other securities) until such tax
      or other charge has been paid or it has been established to the Company's
      satisfaction that no such tax or charge is due.

            (e)   As soon as practicable after the receipt from the holder of
      this Warrant Certificate of notice of the intent to exercise of a number
      of warrants sufficient to require a filing under the Hart Scott-Rodino
      Antitrust Improvements Act of 1976 and the rules, regulations and formal
      interpretations thereunder, as amended from time to time (the "HSR ACT")
      (and after the receipt, if applicable, of the notice referred to in Rule
      803.5 of the HSR Act), but in any event no later than the 15 Business Days
      after receipt of such notice(s), the Company will (i) if required by the
      HSR Act, prepare and file with Antitrust Division of the Department of
      Justice (the "DOJ") and the Federal Trade Commission (the "FTC") the
      Notification and Report Form (accompanied by all documentary attachments
      contemplated thereby) required by the HSR ACT, (ii) upon request of the
      holder, request early termination of the waiting period imposed by the HSR
      Act, and (iii) coordinate and cooperate with the holder in responding to
      formal and informal requests for additional information and documentary
      material from the DOJ and the FTC in connection with such filing.
      Notwithstanding the foregoing, if the holder is required to file with the
      DOJ and FTC the Notification and Report Form solely as a result of its
      holding and/or purchasing shares of Common Stock issued pursuant to this
      Warrant (with no regard to any other securities held by such holder or its
      affiliates) and the holder certifies such fact to the Company in writing,
      the Company agrees to promptly reimburse the holder for all fees and
      expenses for the preparation and filing of such form, including all legal
      expenses and filing fees.

            (f)   The Company will not change the par value of the Common Stock
      from par value $0.01 per share to any higher par value which exceeds the
      Exercise Price then in effect, and will reduce the par value of the Common
      Stock upon any event described in SECTION 2 that would, but for this
      provision, reduce the Exercise Price below the par value of the Common
      Stock.

      SECTION 7. NO RIGHTS AS STOCKHOLDER. The holder of the Warrants shall not,
by virtue of holding such Warrants, be entitled to any rights of a stockholder
of the Company either

                                       9

at law or in equity, and the rights of the holder of the Warrants are limited to
those expressed herein.

hereto shall be in writing and shall be deemed to have been duly given or made

Company shall execute and deliver a new Warrant Certificate or Warrant
Certificates in the name of the assignee or assignees and in the denomination

incorporated, validly existing, and in good standing under the laws of the State
of Delaware and has all requisite corporate power and authority to own, lease,
and operate its properties and to carry on its business in all material respects
as now being conducted. No actions or proceedings to dissolve the Company are
pending or, to the best knowledge of the Company, threatened. The Company is
duly qualified to do business as a foreign corporation and is in good standing
in each jurisdiction where such qualification is necessary, except where the
failure to so qualify or to be in good standing would not reasonably be expected
to have a Material Adverse Effect on the Company.

         3.2 Capitalization of the Company.

         (a) As of the date hereof, the authorized capital stock of the Company
consists of 10,000,000 shares of Common Stock and 2,500,000 shares of preferred

upon exercise of outstanding warrants or conversion rights. All outstanding
shares of capital stock of the Company have been validly issued and are fully
paid and nonassessable, and no shares of capital stock of the Company are
subject to, nor have any been issued in violation of, preemptive or similar
rights.

into or exchangeable for such capital stock or voting securities; and (iv) no
equity equivalents, interests in the ownership or earnings, or other similar
rights of or with respect to the Company.

         (c) Neither the execution of this Agreement nor the performance of the
Company's obligations hereunder, nor the consummation of any other transaction
currently contemplated by the Company or any of its Subsidiaries, will trigger
or cause any adjustment under any anti-dilution provisions or any other similar
provisions contained in any agreement as currently in effect that have the
effect of (i) causing a decrease in any exercise price or conversion price in
any security exercisable for or convertible into shares of Common Stock (a
"Common Stock Equivalent"), or (ii) causing an increase in the number of shares
of Common Stock that may be acquired upon conversion or exercise of a Common
Stock Equivalent.

         3.3 Authority Relative to This Agreement. Subject to the Company
obtaining the Stockholder Approval required by the rules, regulations and
interpretations of the Nasdaq Stock Market, Inc. with respect to the issuance of
the Additional Warrants, the Company has requisite corporate power and authority

the issuance of the Additional Warrants, the execution, delivery and performance
by the Company of this Agreement and the execution, delivery, and where
applicable, performance by it of the Ancillary Documents to which it is a party,
and the consummation by it of the transactions contemplated hereby and thereby,
have been (or prior to the Closing will have been) duly authorized by all
necessary corporate action of the Company. Notwithstanding the foregoing, the
Company has requisite corporate power and authority to perform the Company's
obligations pursuant to Article V, and such performance has been duly authorized
by all necessary corporate action of the Company. This Agreement has been duly
executed and delivered by the Company and constitutes, and each Ancillary
Document executed or to be executed by the Company has been, or when executed
will be, duly executed and delivered by the Company and constitutes, or when
executed and delivered will constitute, a valid and legally binding obligation
of the Company, enforceable against the Company in accordance with its terms,
except that such enforceability may be limited by (i) applicable bankruptcy,
insolvency, reorganization, moratorium, and similar laws affecting creditors'
rights generally, and (ii) general equitable principles (regardless of whether
such enforceability is considered in a proceeding in equity or at law).

         3.4 Noncontravention. The execution, delivery, and performance by the
Company of this Agreement and the execution, delivery, and where applicable, the
performance by it of Ancillary Documents to which it is a party and the
consummation by it of the transactions contemplated hereby and thereby do not

for any such conflicts, violations, defaults, terminations, cancellations,
accelerations, or Encumbrances which would not, or would not reasonably be
likely to, individually or in the aggregate, have a Material Adverse Effect on
the Company.

         3.5 Consents and Approvals. No consent, approval, order, or
authorization of, or declaration, filing, or registration with, any Governmental
Entity is required to be obtained or made by the Company or any Subsidiary in
connection with the execution, delivery, or performance by the Company of this

Warrants and (ii) to approve the amendment and restatement of the Certificate of
Incorporation, no consent or approval of any person other than the Company, the
Investors or any Governmental Entity is required to be obtained or made by the
Company or any Subsidiary in connection with the execution, delivery, or

applicable, performance of the Ancillary Documents to which it is a party or the
consummation of the transactions contemplated hereby and thereby, other than
such consents, approvals, orders, or authorizations which, if not obtained, and
such declarations, filings, or registrations which, if not made, would not,
individually or in the aggregate, have a Material Adverse Effect on the Company.

         3.6 Authorization of Issuance; Reservation of Shares. The issuance,
sale and delivery of the Notes and the Warrants in accordance with this
Agreement, and the issuance and delivery of the Warrant Shares upon exercise of
the Warrants, have been duly authorized by all necessary corporate action on the

the Warrant Shares issuable upon exercise of an Additional Warrant have been
duly and validly reserved and, when issued upon exercise of an Additional
Warrant, will be duly and validly issued, fully paid and nonassessable. The
issuances of the Warrants are not subject to any preemptive or similar rights.

         3.7 Financial Condition. Each of the consolidated balance sheets
included in or incorporated by reference into the Company Reports (including the
related notes and schedules) fairly presents in all material respects the
consolidated financial position of the Company and its Subsidiaries as of its
date, and each of the consolidated statements of income, cash flows and changes
in shareholders' equity included in or incorporated by reference into the
Company Reports (including any related notes and schedules) fairly presents in
all material respects the results of operations, stockholders' equity, and cash
flow of the Company for the periods set forth therein (subject, in the case of
unaudited statements, to (x) such exceptions as may be permitted by Form 10-QSB
and Regulation S-B of the SEC and (y) normal year end audit adjustments), in
each case in accordance with generally accepted accounting principles
consistently applied during the periods involved, except as may be noted
therein. Except as and to the extent set forth on the most recent consolidated
balance sheet of the Company and its Subsidiaries included in the Company
Reports, including all notes thereto, as of the date of such balance sheet,
neither the Company nor any of its Subsidiaries has any liabilities or
obligations of any nature (whether accrued, absolute, contingent or otherwise)
that would be required to be reflected on, or reserved against in, a balance
sheet of the Company or in the notes thereto prepared in accordance with
generally accepted accounting principles consistently applied, other than
liabilities or obligations which do not and are not reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on the Company.
Since June 30, 2004, there has been no change or event having or reasonably
likely to have a Material Adverse Effect on the Company, except as set forth in
the Disclosure Letter delivered by the Company to the Investors
contemporaneously with the execution and delivery of this Agreement (the
"Disclosure Letter").

         3.8 Litigation. Except as disclosed in the Company's annual report on
Form 10-KSB for the fiscal year ended December 31, 2003, or quarterly reports on
Form 10-QSB for the quarters ended March 31, 2004 and June 30, 2004, filed with
the SEC (collectively, the "Company Reports") or as set forth in the Disclosure
Letter, as of the date hereof there is no Proceeding or other action of any
nature pending or, to the knowledge of the Company, threatened against or
affecting the Company or any Subsidiary which may reasonably have a Material
Adverse Effect on the Company.

         3.9 ERISA.

         (a) The Company and each ERISA Affiliate have complied in all material
respects with ERISA and, where applicable, the Code regarding each Plan. Each
Plan is, and has been, maintained in substantial compliance with ERISA and,
where applicable, the Code.

         (b) No act, omission or transaction has occurred which could result in
imposition on the Company or any ERISA Affiliate (whether directly or
indirectly) of an amount of $10,000 or more as (i) either a civil penalty
assessed pursuant to section 502(c), (i) or (1) of ERISA or a tax imposed
pursuant to Chapter 43 of Subtitle D of the Code or (ii) breach of fiduciary
duty liability damages under section 409 of ERISA.

         (c) No Plan that is subject to Title IV of ERISA or any trust created
under any such Plan has been terminated since September 2, 1974. No liability to
the Pension Benefit Guaranty Corporation in excess of $10,000 (other than for
the payment of current premiums which are not

                                       5
<PAGE>

past due) by the Company or any ERISA Affiliate has been or is expected by the
Company or any ERISA Affiliate to be incurred with respect to any Plan.

         (d) Full payment when due has been made of all amounts which the
Company or any ERISA Affiliate is required under the terms of each Plan or
applicable law to have paid as contributions to such Plan, and no accumulated
funding deficiency in an amount of $10,000 or more (as defined in section 302 of
ERISA and section 412 of the Code), whether or not waived, exists with respect
to any Plan.

         (e) The actuarial present value of the benefit liabilities under each
Plan which is subject to Title IV of ERISA does not, as of the end of the
Company's most recently ended fiscal year, exceed the current value of the
assets (computed on a plan termination basis in accordance with Title IV of
ERISA) of such Plan allocable to such benefit liabilities by $10,000 or more.
The term "actuarial present value of the benefit liabilities" shall have the
meaning specified in section 4041 of ERISA.

         (f) None of the Company or any ERISA Affiliate sponsors, maintains, or
contributes to an employee welfare benefit plan, as defined in section 3(1) of
ERISA, including, without limitation, any such plan maintained to provide
benefits to former employees of such entities, that may not be terminated by the
Company or any ERISA Affiliate in its sole discretion at any time without any
material liability (other than run off liability in the ordinary course of
payment of benefits or as mandated by Applicable Law).

         (g) None of the Company or any ERISA Affiliate sponsors, maintains or
contributes to, or has at any time in the preceding six calendar years,
sponsored, maintained or contributed to, any Multiemployer Plan.

         (h) None of the Company or any ERISA Affiliate is required to provide
security under section 401(a)(29) of the Code due to a Plan amendment that
results in an increase in current liability for the Plan.

         (i) The Disclosure Letter lists all Plans that the Company or any ERISA
Affiliate has had at any time in the prior six (6) years.

         3.10 Taxes. Except as described in the Disclosure Letter, the Company
has filed all United States Federal income tax returns and all other tax returns
which are required to be filed by it and has paid all taxes due pursuant to such
returns or pursuant to any assessment received by the Company, except for any
taxes which are being contested in good faith and by proper proceedings and
against which adequate reserves are being maintained. The charges, accruals and
reserves in respect of taxes and other governmental charges set forth on the
face of the most recent balance sheet included in the most recent Company Report
are, in the opinion of the Company, adequate. No tax lien has been filed and, to
the knowledge of the Company, no claim is being asserted with respect to any
such tax, fee or other charge, except for any taxes, fees or other charges which
are being contested in good faith and by proper proceedings and against which
adequate reserves are being maintained.

or valid leasehold interests to its assets and Properties, including, without
limitation, the Oil and Gas Properties, free and clear of all Liens, other than
Excepted Liens, except for minor defects and irregularities in title that are
not substantial in character, amount, or extent. Except for immaterial
divergences, after giving full effect to the Excepted Liens, the Company owns,
in all material respects, the net interests in production attributable to the
Hydrocarbon Interests, and the ownership of such Hydrocarbon Interests shall not
in any material respect obligate the Company to bear the costs and expenses
relating to the maintenance, development and operations of each such Hydrocarbon
Interest in an amount in excess of the working interest of such Hydrocarbon
Interest (without a corresponding increase in net revenue interest).

         (b) All leases, licenses, permits, authorizations and agreements
necessary for the conduct of the business of the Company and the Subsidiaries
are valid and subsisting, in full force and effect and there exists no default
or event or circumstance which with the giving of notice or the passage of time
or both would give rise to a default under any such leases, licenses, permits,
authorizations and agreements, which would have a Material Adverse Effect on the
conduct of the business of the Company or its Subsidiaries.

         (c) The Properties, including, without limitation, the Oil and Gas
Properties, presently owned, leased or licensed by the Company and the
Subsidiaries, including, without limitation, all easements, licenses, permits,
authorizations and rights of way, include all Properties necessary to permit the
Company and the Subsidiaries to conduct their business in all material respects
in the same manner as its business has been conducted prior to the Closing Date.

         (d) Except as described in the Disclosure Letter, all of the Properties
of the Company and the Subsidiaries which are reasonably necessary for the
operation of their business are in good working condition in all material
respects and are maintained in accordance with prudent business standards.

         3.12 No Material Misstatements. Taken as a whole, the written
information, statements, exhibits, certificates, documents and reports furnished
to the Investors by the Company or any Subsidiary in connection with the
negotiation of this Agreement do not contain any material misstatement of fact
or omit to state a material fact or any fact necessary to make the statements
contained therein not materially misleading in the light of the circumstances in
which made and with respect to the Company or any Subsidiary. The Company does
not represent or warrant that any occurrences, developments or facts, including,
without limitation, projections and forecasts, will in fact occur or eventuate
after such date, but the Company represents and warrants that such occurrences,
developments or facts, including, without limitation, such projections and
forecasts, were prepared by the Company in good faith based on its best
knowledge, information and belief. There is no fact peculiar to the Company or
Subsidiary which has a Material Adverse Effect relative to the Company or in the
future may reasonably have a Material Adverse Effect and which has not been
disclosed in this Agreement or the other documents, certificates and statements
furnished to the Investors by or on behalf of

                                       7
<PAGE>

the Company or any Subsidiary prior to, or on, each Closing Date in connection
with the transactions contemplated hereby.

         3.13 Investment Company Act. Neither the Company nor any Subsidiary is
an "investment company" or a company "controlled" by an "investment company,"

         3.14 Public Utility Holding Company Act. The Company and its affiliates
and Subsidiaries are not, and after giving effect to the performance of the
terms of this Agreement will not be, subject to regulation (i) as a "holding
company," a "subsidiary company" of a "holding company," an "affiliate" of a
"holding company," an "affiliate" of a "subsidiary company" of a "holding
company," or an "associate company" of a "holding company," in each case as such

respect to rates or the financial or organizational regulation of a
"public-utility company," as defined in PUHCA. Neither the Company, nor any
"subsidiary company" (as defined in PUHCA) of the Company, directly or
indirectly owns, controls or holds with power to vote, five percent (5%) or more
of the outstanding voting securities of (A) any "holding company," (B) any "gas
utility company," or (C) any "electric utility company" (as such terms are
defined in PUHCA).

         3.15 Subsidiaries. Except as set forth in the Company Reports or the
Disclosure Letter, the Company has no Subsidiaries. Each Subsidiary is a
corporation or limited liability company, duly incorporated or organized,
validly existing and in good standing under the laws of its jurisdiction of
incorporation or organization, as applicable, and has all requisite corporate or
other power and authority in all material respects to own, lease, and operate
its properties and to carry on its business as now being conducted. Each
Subsidiary is duly qualified to do business as a foreign corporation or limited
liability company, as applicable, and is in good standing in each jurisdiction
where such qualification is necessary, except where the failure to so qualify or
to be in good standing would not reasonably be expected to have a Material
Adverse Effect on the Company or such Subsidiary. Except as set forth in the
Disclosure Letter, there are outstanding (i) no securities of any Subsidiary
convertible into or exchangeable for shares of capital stock or other voting
securities of any Subsidiary and (ii) no options or other rights to acquire from

of any Subsidiary convertible into or exchangeable for such capital stock or
voting securities.

         3.16 Defaults. Neither the Company nor any Subsidiary is in default nor
has any event or circumstance occurred which, but for the expiration of any
applicable grace period or the giving of notice, or both, would constitute a
default under any Material Agreement to which the Company is a party or by which
the Company is bound.

         3.17 Environmental Matters.

         (a) No Property owned, leased or operated by the Company or any of its
Subsidiaries, including, without limitation, any Oil and Gas Property of the

and, to the best knowledge of the Company, all such transport carriers and
treatment and disposal facilities have been and are operating in compliance with
applicable Environmental Laws and so as not to pose an imminent and substantial
endangerment to public health or welfare or the environment, and are not the

compliance with applicable Environmental Laws and so as not to pose an imminent
and substantial endangerment to public health or welfare or the environment;

         (f) To the extent applicable, all Oil and Gas Property of the Company
and each of its Subsidiaries currently satisfies all design, operation, and
equipment requirements imposed by the OPA; and

         (g) Neither the Company nor any of its Subsidiaries has any known
contingent liability in connection with any release or threatened release of any
oil, hazardous substance or solid waste into the environment.

                                       9
<PAGE>

         (h) Notwithstanding anything in this Section 3.17 to the contrary, the
representations and warranties in this Section 3.17 regarding the Oil and Gas
Properties of the Company and the Subsidiaries shall be limited to the knowledge
of the Company and its Subsidiaries.

         3.18 Compliance with the Law. Neither the Company nor any Subsidiary
has violated any Governmental Requirement or failed to obtain any license,
permit, franchise or other governmental authorization necessary for the
ownership of any of its Properties, including, without limitation, its Oil and
Gas Properties, or the conduct of its business, which violation or failure would
have (in the event such violation or failure were asserted by any Person through
appropriate action) a Material Adverse Effect. Except for such acts or failures
to act as would not have a Material Adverse Effect, the Properties, including,
without limitation, the Oil and Gas Properties (and properties unitized
therewith), have been maintained, operated and developed in a good and
workmanlike manner and in conformity with all applicable laws and all rules,
regulations and orders of all duly constituted authorities having jurisdiction
and in conformity with the provisions of agreements and other instruments
comprising a part of the Properties, including, without limitation, all leases,
subleases or other contracts comprising a part of the Hydrocarbon Interests and
other contracts and agreements forming a part of the Oil and Gas Properties;
specifically in this connection, but subject to the Material Adverse Effect
qualification set forth above, (i) after the date hereof, no Oil and Gas
Property is subject to having allowable production reduced below the full and
regular allowable (including the maximum permissible tolerance) because of any
overproduction (whether or not the same was permissible at the time) prior to
the date hereof, and (ii) none of the wells comprising a part of the Oil and Gas
Properties (or properties unitized therewith) are deviated from the vertical
more than the maximum permitted by applicable laws, regulations, rules and
orders, and such wells are, in fact, bottomed under and are producing from, and
the well bores are wholly within, the Oil and Gas Properties (or in the case of
wells located on properties unitized therewith, such unitized properties). This
Section 3.18 does not apply to compliance with ERISA or applicable Environmental
Laws, which are instead subject to Section 3.9 and Section 3.17, respectively.

         3.19 Insurance. The Disclosure Letter contains an accurate and complete
description of all material policies of fire, liability, workmen's compensation
and other forms of insurance owned or held by the Company and each Subsidiary as
of the date hereof. Except as set forth in the Disclosure Letter, all such
policies are in full force and effect, all premiums with respect thereto
covering all periods up to and including the date hereof and the Additional
Closing Date have been, or will be, paid, and no notice of cancellation or
termination has been received with respect to any such policy. Such policies are
sufficient for compliance with all requirements of law and of all agreements to
which the Company or any Subsidiary is a party; are valid, outstanding and
enforceable policies; provide adequate insurance coverage in at least such
amounts and against at least such risks (but including in any event public
liability) as are usually insured against in the same general area by companies
engaged in the same or a similar business for the assets and operations of the
Company and each Subsidiary; will remain in full force and effect through the
respective dates set forth in the Disclosure Letter with the payment of
additional premiums; and, except as set forth in the Disclosure Letter, will not
in any way be affected by, or terminate or lapse by reason of, the transactions
contemplated by this Agreement. There are no material risks that the Company,
the Subsidiaries or their respective Board of Directors or officers have
designated as being self-insured. Neither the Company nor any Subsidiary has
been refused any insurance with respect to its assets or operations, nor has its

                                       10
<PAGE>

coverage been limited below usual and customary policy limits, by an insurance
carrier to which it has applied for any such insurance or with which it has
carried insurance during the last three years. Without limiting the foregoing,
the Company has in effect directors and officers insurance coverage in an annual
aggregate amount of not less than $5 million.

         3.20 Hedging Agreements. As of the date hereof, there are no Hedging
Agreements (including commodity price swap agreements, forward agreements or
contracts of sale which provide for prepayment for deferred shipment or delivery
of oil, gas or other commodities) of the Company or any Subsidiary.

         3.21 Material Agreements. Set forth on the Disclosure Letter hereto is
a complete and correct list of all Material Agreements, purchase agreements,
obligations in respect of letters of credit, guarantees, joint venture
agreements, and other instruments in effect or to be in effect as of the date
hereof (other than Hedging Agreements) providing for, evidencing, securing or
otherwise relating to any material Debt of the Company or any Subsidiary, and
all obligations of the Company or any Subsidiary to issuers of surety or appeal
bonds (excluding operator's bonds, plugging and abandonment bonds, and similar
surety obligations obtained in the ordinary course of business) issued for
account of the Company or any such Subsidiary.

         3.22 Gas Imbalances. As of the date hereof, on a net basis there are no
gas imbalances, take or pay or other prepayments with respect to the Company's
or any Subsidiary's Hydrocarbon Interests which would require the Company or
such Subsidiary to deliver five percent (5%) or more of the monthly production
from the Company's and its Subsidiaries' Hydrocarbons produced on a monthly
basis from the Hydrocarbon Interests, at some future time without then or
thereafter receiving full payment therefor.

         3.23 Brokerage Fees. The Company has not retained any financial
advisor, broker, agent, or finder or paid or agreed to pay any financial
advisor, broker, agent, or finder on account of the sale by the Company and the
purchase by the Investors of the Notes and the Warrants pursuant to this
Agreement, except for Sanders Morris Harris, Inc. ("SMH").

         3.24 SEC Filings. During the preceding three (3) years, the Company has
complied in all material respects with its obligations to file with the SEC all
forms, reports, schedules, statements and other documents required to be filed
by it under the Securities Act and the Exchange Act. All forms, reports,
schedules, statements, and other documents (including all amendments thereto)
filed by the Company with the SEC since such date are herein collectively
referred to as the "SEC Filings." The SEC Filings, at the time filed, complied
in all material respects with all applicable requirements of federal securities
laws. None of the SEC Filings, including, without limitation, any financial
statements or schedules included therein, at the time filed or as same may have
been amended, contained any untrue statement of a material fact or omitted to
state any material fact required to be stated therein or necessary in order to
make the statements contained therein, in light of the circumstances under which
they were made, not misleading.

         3.25 NASDAQ Listing. The Common Stock is listed on the Nasdaq Smallcap
Market and the Company has taken no action designed to, or likely to have the
effect of, de-listing the Common Stock from the Nasdaq Smallcap Market. Except
as set forth in the Disclosure Letter,

                                       11
<PAGE>

the Company has not been contacted regarding any listing qualification issues
within the twelve (12) month period preceding the date of this Agreement.

<PAGE>

         4.4 Consents and Approvals. No consent, approval, order, or
authorization of, or declaration, filing, or registration with, any Governmental
Entity is required to be obtained or made by such Investor in connection with
the execution, delivery, or performance by such Investor of this Agreement. No

delivery and, where applicable, performance of the Ancillary Documents to which

         4.5 Purchase for Investment. Such Investor understands that none of the
Notes, the Warrants or the Warrant Shares have been registered under the
Securities Act. Such Investor also understands that the Notes, the Warrants and
the Warrant Shares are being offered and sold pursuant to an exemption from
registration contained in the Securities Act based in part upon such Investors'
representations contained in this Agreement. Such Investor hereby represents and
warrants as follows:

         (a) Investor Bears Economic Risk. Such Investor has substantial
experience in evaluating and investing in private placement transactions of
securities in companies similar to the Company so that it is capable of
evaluating the merits and risks of its investment in the Company and has the
capacity to protect its own interests. Without limiting the generality of the
foregoing, such Investor further represents that it has such knowledge regarding
the pipeline and the oil and gas industries and the business of the Company and
the current circumstances surrounding such industries and business that it is
capable of evaluating the merits and risks of the acquisition of the Notes, the
Warrants and the Warrant Shares. Such Investor must bear the economic risk of
this investment indefinitely unless the Notes, the Warrants or the Warrant
Shares are registered pursuant to the Securities Act, or an exemption from
registration is available. Such Investor understands that, except as provided in
Section 5.12, the Company has no present intention of registering the Warrants
or the Warrant Shares. Such Investor also understands that there is no assurance
that any exemption from registration under the Securities Act will be available
and that, even if available, such exemption may not allow such Investor to
transfer all or any portion of the Notes, the Warrants or the Warrant Shares
under the circumstances, in the amounts or at the times such Investor might
propose.

         (b) Acquisition for Own Account. Such Investor is acquiring the Notes,
the Warrants and the Warrant Shares for such Investor's own account for
investment only, and not with a view towards their distribution.

         (c) Investor Can Protect Its Interest. Such Investor represents that by
reason of its, or of its management's, business or financial experience, such
Investor has the capacity to protect its own interests in connection with the
transactions contemplated in this Agreement and the Ancillary Documents.
Further, such Investor is not aware of any publication of any advertisement in
connection with the transactions contemplated in this Agreement.

         (d) Accredited Investor. Such Investor represents that (i) it is an
accredited investor within the meaning of Regulation D under the Securities Act
and, (ii) if such Investor is an entity all of its equity owners are accredited
investors.

                                       13
<PAGE>

         (e) Company Information. Such Investor has had access to the Company's
SEC Filings and has had an opportunity to discuss the Company's business,
management and financial affairs with directors, officers and management of the
Company and has had the opportunity to review the Company's operations and
facilities. Such Investor has also had the opportunity to ask questions of, and
receive answers from, the Company and its management regarding the terms and
conditions of this investment. Such Investor hereby acknowledges and affirms
that it has completed its own independent investigation, analysis, and
evaluation of the Company and its subsidiaries, that it has made all such
reviews and inspections of the business, assets, results of operations,
condition (financial or otherwise), and prospects of the Company and its
subsidiaries as it has deemed necessary or appropriate, and that in making its
decision to enter into this Agreement and to consummate the transactions
contemplated hereby it has relied solely on its own independent investigation,
analysis, and evaluation of the Company and its subsidiaries, or that of its own
independent advisers in evaluating its investment in the Notes, the Warrants and
the Warrant Shares.

         (f) Rule 144. Such Investor acknowledges and agrees that the Warrants,
and, if issued, the Warrant Shares, must be held indefinitely unless they are
subsequently registered under the Securities Act or an exemption from such
registration is available. Such Investor has been advised or is aware of the
provisions of Rule 144, which permits limited resale of shares purchased in a
private placement subject to the satisfaction of certain conditions, including,
among other things: the availability of certain current public information about
the Company, the resale occurring following the required holding period under
Rule 144 and the number of shares being sold during any three-month period not
exceeding specified limitations.

         (g) Transfer Restrictions. Such Investor acknowledges and agrees that
the Warrants and the Warrant Shares are subject to restrictions on transfer as
set forth in Section 5.5, and further understands that the Notes, the Warrants
and the Warrant Shares will not have been registered pursuant to the Securities
Act or any applicable state securities laws, that the Notes, the Warrants and
the Warrant Shares will be characterized as "restricted securities" under
federal securities laws, and that under such laws and applicable regulations the
Notes, the Warrants and the Warrant Shares cannot be sold or otherwise disposed
of without registration under the Securities Act or an exemption therefrom. In
this connection, such Investor represents that it is familiar with Rule 144
promulgated under the Securities Act, as currently in effect, and understands
the resale limitations imposed thereby and by the Securities Act. Appropriate
stop transfer instructions may be issued to the transfer agent for securities of
the Company (or a notation may be made in the appropriate records of the
Company) in connection with the Warrants or the Warrant Shares.

         (h) Confirmation. The acquisition of the Notes, the Warrants by an
Investor at the Closing shall constitute such Investor's confirmation of the
foregoing representations.

         4.6 No Other Shares. Except for such rights as may be conferred on an
Investor by this Agreement and the Ancillary Documents and certain Common Stock
and options to acquire Common Stock owned by Michael S. Chadwick, the Investors
do not beneficially own, directly or indirectly, any shares of capital stock or
other securities of the Company or any of its Subsidiaries.

                                       14

         4.7 Financial Resources. Such Investor has the financial resources
available to it as are necessary to perform its obligations to acquire the Notes
and the Warrants pursuant to the terms of this Agreement.

         4.8 Brokerage Fees. Such Investor has not retained any financial
advisor, broker, agent, or finder or paid or agreed to pay any financial
advisor, broker, agent, or finder on account of the sale by the Company and the
purchase by the Investors of the Warrants pursuant to this Agreement.

         4.9 Proxy Statement. None of the information supplied or to be supplied
by such Investor for inclusion or incorporation by reference in the proxy
statement relating to the Company's special stockholders meeting convened for
the purpose of obtaining the Stockholder Approval (the "Special Meeting") will,
at the date the proxy statement is mailed to the Company's stockholders and at
the time of the Special Meeting, contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they are made, not misleading. If prior to the Special Meeting any of such
information supplied by such Investor is no longer accurate, such Investor shall
promptly notify the Company of such inaccuracy and shall provide such additional
information as reasonably requested by the Company to correct such inaccuracy.

         4.10 No General Solicitations. Neither the Investor, nor any of its
officers, directors, employees, agents, stockholders or partners, if applicable,
has either directly or indirectly, including through a broker or a finder (a)
engaged in any general solicitations, or (b) published any advertisement in
connection with the offer and sale of the Warrants.

         4.11 Exchange Act Filings. The Investors agree to comply with their
obligations under the Exchange Act. None of the information included in any such
filing will contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they are made, not
misleading. If any event shall occur which is required to be described in any
such filing, such event shall so be described, and an amendment shall be filed
promptly with the SEC.

         shall have furnished the Company with an opinion of counsel, which

         5.12 Registration of Warrant Shares.

         (a) The Company shall prepare and file with the SEC a registration
statement on Form S-3, or any similar short-form registration under the
Securities Act (the "Form S-3"), to register for resale from time to time, the
Common Stock representing the Warrant Shares and the Director Warrants (the
"Registrable Securities") promptly, but in no event more than 60 days following
the Company's first Form 10-KSB filing after the Closing Date, and use its best
efforts to cause the Form S-3 to become effective and remain effective for the
period described in Section 5.12(c)(ii). As used herein, "register,"
"registered" and "registration" refer to a registration effected by preparing
and filing the Form S-3, a registration statement or similar document (a
"Registration Statement") in compliance with the Securities Act, and the
declaration or order of effectiveness of such Registration Statement.

                  If the Company at any time proposes to file on its behalf
         and/or on behalf of any of its security holders other than the
         Investors ("Demanding Security Holders") a Registration Statement under
         the Securities Act on any form (other than a Registration Statement
         filed on Form S-4, Form S-8 or any similar or successor form or any
         other Registration Statement relating to an offering of securities
         solely to the Company's existing security holders or employees) to
         register the offer and sale of its Common Stock for cash, it will give
         written notice to the Investors at least twenty (20) days before the
         anticipated date of initial filing with the SEC of such Registration
         Statement, which notice shall set forth the Company's intention to
         effect such a registration, the class or series and number of equity
         securities proposed to be registered and the intended method

                                       19
<PAGE>

         of disposition of the securities proposed to be registered by the
         Company. The notice shall offer to include in such filing all of the
         Registrable Securities.

                  (i) If any Investor desires to have Registrable Securities
         registered under this Section 5.12(b), it shall advise the Company in
         writing within fifteen (15) days after the date of receipt of such
         offer from the Company, setting forth the amount of such Registrable
         Securities for which registration is requested. The Company shall
         thereupon include in such filing the number of Registrable Securities
         for which registration is so requested, subject to the next sentence,
         and shall use commercially reasonable efforts to effect registration
         under the Securities Act of such Registrable Securities. If the
         managing underwriter of a proposed public offering shall advise the
         Company in writing that, in its opinion, the distribution of the
         Registrable Securities requested to be included in the registration
         concurrently with the securities being registered by the Company or any
         Demanding Security Holder would materially and adversely affect the
         distribution of such securities by the Company or such Demanding
         Security Holders, then all selling security holders (but not the
         Company or the Demanding Security Holders) shall reduce the amount of
         Registrable Securities of each intended to be distributed through such
         offering on a pro rata basis to the greatest aggregate amount that, in
         the opinion of such managing underwriter, would not materially and
         adversely affect the distribution of such securities.

                  (ii) Nothing in this Section 5.12(b) shall preclude the
         Company from discontinuing the registration of its securities being
         affected on its behalf under this Section 5.12(b) at any time prior to
         the effective date of the registration relating thereto.

         (b) In connection with the Company's registration obligations pursuant
to this Section 5.12, the Company shall keep each Registration Statement
continuously effective to permit the sale of Registrable Securities covered by
such Registration Statement in accordance with the intended method or methods of
distribution thereof specified in such Registration Statement or in the related
prospectus(es), and shall:

                  (i) prepare and file with the SEC a Registration Statement
         with respect to such securities and use commercially reasonable efforts
         to cause such Registration Statement to become and remain effective for
         the period described in paragraph (f) below;

                  (ii) prepare and file with the SEC such amendments and
         supplements to such Registration Statement and the prospectus used in
         connection therewith as may be necessary to keep such Registration
         Statement effective and to comply with the provisions of the Securities
         Act with respect to the sale or other disposition of all securities
         covered by such Registration Statement until such time as all of such
         securities have been disposed of in a public offering;

                  (iii) furnish to such selling security holders such number of
         copies of a summary prospectus or other prospectus, including a
         preliminary prospectus, in conformity with the requirements of the
         Securities Act, and such other documents, as

                                       20
<PAGE>

         such selling security holders may reasonably request to facilitate the
         disposition of all Registrable Securities covered by the Registration
         Statement;

                  (iv) use commercially reasonable efforts to register or
         qualify the securities covered by such Registration Statement under
         such other securities or blue sky laws of such jurisdictions within the
         United States as each holder of such securities shall reasonably
         request (provided, however, the Company shall not be obligated to
         qualify as a foreign corporation to do business under the laws of any
         jurisdiction in which it is not then qualified to file any general
         consent to service or process), and do such other reasonable acts and
         things as may be required of it to enable such holder to consummate the
         disposition in such jurisdiction of the securities covered by such
         Registration Statement;

                  (v) use commercially reasonable efforts to cause all
         Registrable Securities covered by each Registration Statement to be
         listed on the Nasdaq SmallCap Market, or, if the Common Stock of the
         Company is not listed thereon, on any national securities exchange, or
         inter-dealer quotations system (including Nasdaq) if any, on which the
         Common Stock is then listed or authorized for trading; and

                  (vi) otherwise use commercially reasonable efforts to comply
         with all applicable rules and regulations of the SEC or
         over-the-counter market where the Common Stock is then listed.

         (c) All expenses incurred in complying with this Section 5.12,
including, without limitation, all registration and filing fees (including all
expenses incident to filing with the NASD), printing expenses, fees and
disbursements of counsel for the Company, expenses of any special audits
incident to or required by any such registration and expenses of complying with
the securities or blue sky laws of any jurisdictions pursuant to Section
5.12(b)(iv), shall be paid by the Company.

         (d) With respect to any Registration Statement filed or to be filed
pursuant to this Section 5.12, if the Company's Board of Directors determines
that, in its good faith judgment, it would (because of the existence of, or in
anticipation of, any acquisition or corporate reorganization or other
transaction, financing activity, stock repurchase or other development involving
the Company, or the unavailability for reasons substantially beyond the
Company's control of any required financial statements, or any other event or
condition of similar significance to the Company) be disadvantageous (a
"Material Development Condition") to the Company or its stockholders for such a
Registration Statement to become effective or to be maintained effective or for
sales of Registrable Securities to continue pursuant to the Registration
Statement, the Company shall, notwithstanding any other provisions of this
Agreement, be entitled, upon the giving of a written notice that a Material
Development Condition has occurred (a "Delay Notice") from an officer of the
Company to all affected holders of Registrable Securities, (i) to cause sales of
Registrable Securities pursuant to such Registration Statement to cease, (ii) to
cause such Registration Statement to be withdrawn and the effectiveness of such
Registration Statement terminated, or (iii) in the event no such Registration
Statement has yet been filed or declared effective, to delay filing or
effectiveness of any such Registration Statement until, in the good faith
judgment of the Company's Board

                                       21
<PAGE>

of Directors, such Material Development Condition no longer exists (notice of
which the Company shall promptly deliver to all affected holders of Registrable
Securities). Notwithstanding the foregoing provisions of this Section 5.12(e):
(1) in no event may any cessation or delay by the Company pursuant to this
Section 5.12(e) be for a period of more than one hundred twenty (120)
consecutive days from the giving of the Delay Notice with respect to a Material
Development Condition, as above provided, and in no event may such right be
exercised by the Company on more than two (2) occasions during any period of
twelve (12) consecutive months; and (2) in the event a Registration Statement is
filed and subsequently withdrawn by reason of any existing or anticipated
Material Development Condition as hereinbefore provided, the Company shall cause
a new Registration Statement covering the same Registrable Securities as those
covered by the original Registration Statement to be filed with the SEC as soon
as practicable after such Material Development Condition expires or, if sooner,
as soon as practicable after such 120 day period expires.

         (e) The registration rights granted under this Section 5.12 shall
terminate as to each Investor when all of the Registrable Securities of such
Investor (i) shall have been effectively registered under the Securities Act and
disposed of in a public offering pursuant to a Registration Statement, (ii)
shall have been sold pursuant to Rule 144 (or any successor provision) under the
Securities Act, (iii) shall have been otherwise transferred and a new
certificate for such Warrant Shares not bearing a legend restricting further
transfer shall have been delivered by the Company, (iv) with respect to a
particular Investor, at any time when all of such Investor's remaining Warrant
Shares can be sold in a single transaction in compliance with Rule 144 under the
Securities Act, or (v) when the Warrants, and all of the associated Warrant
Shares, shall have ceased to be outstanding.

         (f) Except as contemplated in this Agreement as required by applicable
securities laws, the Common Stock registered pursuant to the Registration
Statement shall not be subject to any blackout, suspension or other trading
restrictions. The Company shall give notice to the holders of Registrable
Securities by email and/or facsimile of the Company's request for acceleration
and of the effectiveness of the Registration Statement with the SEC,
respectively, on the respective days that each of those events occur.

         (g) The prospectus included in the Registration Statement (the
"Prospectus") shall not be considered to be "current" at any time when, by
reason of occurrence of any event or by reason of the passage of time, the
Prospectus does not meet the requirements of Section 10 of the Securities Act,
or the Prospectus contains an untrue statement of a material fact or omits to
state any material fact required to be stated therein or necessary to make the
statements therein not misleading. The Prospectus shall disclose that holders of
Registrable Securities may elect to resell Registrable Securities without
registration of such sales under the Registration Statement, by making such
sales under and as permitted by Rule 144 of the SEC under the Act.

         (h) Each Investor agrees in connection with any registration of the
Company's securities upon the request of the Company and the underwriters
managing any underwritten offering of the Company's securities, not to sell,
make any short sale of, loan, grant any option for the purchase of, or otherwise
dispose of any Registrable Securities (other than those included in the
registration) without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time not to exceed one
hundred twenty

                                       22
<PAGE>

(120) days from the effective date of such registration as the Company and the
underwriters may specify, so long as all officers and directors of the Company
are bound by a comparable obligation provided, however, that nothing herein
shall prevent any Investor from making a distribution of Registrable Securities
to the partners or shareholders thereof that is otherwise in compliance with
applicable securities laws, so long as such distributees agree to be so bound.

         5.13 Confidentiality. Each Investor hereto agrees to treat all
non-public information concerning the Company and its affiliates and
Subsidiaries which was furnished by or on behalf of the Company, whether
furnished before, on or after the date hereof confidential.

         5.14 Directors Warrants. The Company agrees to issue Warrants to
acquire 100,000 shares of Common Stock to each Investor Nominee and Michael S.
Chadwick as promptly as practicable after the Special Meeting.
