                                                                    EXHIBIT B

NEITHER THIS SECURITY NOR THE SECURITIES INTO WHICH THIS SECURITY IS EXERCISABLE
HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE
SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM
REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN
AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE
SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO
SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE
COMPANY. THIS SECURITY AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS
SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER

                          COMMON STOCK PURCHASE WARRANT

                To Purchase __________ Shares of Common Stock of

                             PDG ENVIRONMENTAL, INC.

            THIS COMMON STOCK PURCHASE WARRANT (the "Warrant") certifies that,
for value received, _____________ (the "Holder"), is entitled, upon the terms
and subject to the limitations on exercise and the conditions hereinafter set
forth, at any time on or after the date hereof (the "Initial Exercise Date") and
on or prior to the close of business on the fifth anniversary of the Initial
Exercise Date (the "Termination Date") but not thereafter, to subscribe for and
purchase from PDG Environmental, Inc., a Delaware corporation (the "Company"),
up to ______ shares (the "Warrant Shares") of Common Stock, par value $0.02 per
share, of the Company (the "Common Stock"). The purchase price of one share of
Common Stock under this Warrant shall be equal to the Exercise Price, as defined
in Section 2(b).

      Section 1. Definitions. Capitalized terms used and not otherwise defined
herein shall have the meanings set forth in that certain Securities Purchase
Agreement (the "Purchase Agreement"), dated July 1, 2005, among the Company and
the purchasers signatory thereto.

      Section 2. Exercise.

            a) Exercise of Warrant. Exercise of the purchase rights represented
      by this Warrant may be made, in whole or in part, at any time or times on
      or after the Initial Exercise Date and on or before the Termination Date
      by delivery to the Company of a duly executed facsimile copy of the Notice
      of Exercise Form annexed hereto (or such other office or agency of the
      Company as it may designate by notice in writing to the registered Holder
      at the address of such Holder appearing on the books of the Company);

                                       1

<PAGE>

      provided, however, within 5 Trading Days of the date said Notice of
      Exercise is delivered to the Company, the Holder shall have surrendered
      this Warrant to the Company and the Company shall have received payment of
      the aggregate Exercise Price of the shares thereby purchased by wire
      transfer or cashier's check drawn on a United States bank.

            b) Exercise Price. The exercise price of the Common Stock under this
      Warrant shall be $____1, subject to adjustment hereunder (the "Exercise
      Price").

            c) Cashless Exercise. If at any time after one year from the date of
      issuance of this Warrant there is no effective Registration Statement
      registering, or no current prospectus available for, the resale of the
      Warrant Shares by the Holder, then this Warrant may also be exercised at
      such time by means of a "cashless exercise" in which the Holder shall be
      entitled to receive a certificate for the number of Warrant Shares equal
      to the quotient obtained by dividing [(A-B) (X)] by (A), where:

            (A)   = the VWAP on the Trading Day immediately preceding the date
                    of such election;

            (B)   = the Exercise Price of this Warrant, as adjusted; and

            (X)   = the number of Warrant Shares issuable upon exercise of this
                    Warrant in accordance with the terms of this Warrant by
                    means of a cash exercise rather than a cashless exercise.

            Notwithstanding anything herein to the contrary, on the Termination
      Date, this Warrant shall be automatically exercised via cashless exercise
      pursuant to this Section 2(c).

            d) Exercise Limitations.

                        i. Holder's Restrictions. The Holder shall not have the
                  right to exercise any portion of this Warrant, pursuant to
                  Section 2(c) or otherwise, to the extent that after giving
                  effect to such issuance after exercise, the Holder (together
                  with the Holder's affiliates), as set forth on the applicable
                  Notice of Exercise, would beneficially own in excess of 9.99%
                  of the number of shares of the Common Stock outstanding
                  immediately after giving effect to such issuance. For purposes
                  of the foregoing sentence, the number of shares of Common
                  Stock beneficially owned by the Holder and its affiliates
                  shall include the number of shares of Common Stock issuable
                  upon exercise of this Warrant with respect to which the
                  determination of such sentence is being made, but shall
                  exclude the number of shares of Common Stock which would be
                  issuable upon (A) exercise of the remaining, nonexercised
                  portion of this Warrant beneficially owned by the Holder or
                  any of its affiliates and (B) exercise or conversion of the

----------
(1)   50% of the Warrants shall have an exercise price equal to $1.11 and 50%
shall have an exercise price equal to $1.33, subject to adjustment.

                                       2

                  unexercised or nonconverted portion of any other securities of
                  the Company (including, without limitation, any other Shares
                  or Warrants) subject to a limitation on conversion or exercise
                  analogous to the limitation contained herein beneficially
                  owned by the Holder or any of its affiliates. Except as set
                  forth in the preceding sentence, for purposes of this Section
                  2(d), beneficial ownership shall be calculated in accordance
                  with Section 13(d) of the Exchange Act, it being acknowledged
                  by Holder that the Company is not representing to Holder that
                  such calculation is in compliance with Section 13(d) of the
                  Exchange Act and Holder is solely responsible for any
                  schedules required to be filed in accordance therewith. To the
                  extent that the limitation contained in this Section 2(d)
                  applies, the determination of whether this Warrant is
                  exercisable (in relation to other securities owned by the
                  Holder) and of which a portion of this Warrant is exercisable
                  shall be in the sole discretion of such Holder, and the
                  submission of a Notice of Exercise shall be deemed to be such
                  Holder's determination of whether this Warrant is exercisable
                  (in relation to other securities owned by such Holder) and of
                  which portion of this Warrant is exercisable, in each case
                  subject to such aggregate percentage limitation, and the
                  Company shall have no obligation to verify or confirm the
                  accuracy of such determination. For purposes of this Section
                  2(d), in determining the number of outstanding shares of
                  Common Stock, the Holder may rely on the number of outstanding
                  shares of Common Stock as reflected in (x) the Company's most
                  recent Form 10-Q or Form 10-K, as the case may be, (y) a more
                  recent public announcement by the Company or (z) any other
                  notice by the Company or the Company's Transfer Agent setting
                  forth the number of shares of Common Stock outstanding. Upon
                  the written or oral request of the Holder, the Company shall
                  within two Trading Days confirm orally and in writing to the
                  Holder the number of shares of Common Stock then outstanding.
                  In any case, the number of outstanding shares of Common Stock
                  shall be determined after giving effect to the conversion or
                  exercise of securities of the Company, including this Warrant,
                  by the Holder or its affiliates since the date as of which
                  such number of outstanding shares of Common Stock was
                  reported. The provisions of this Section 2(d) may be waived by
                  the Holder upon, at the election of the Holder, not less than
                  61 days' prior notice to the Company, and the provisions of
                  this Section 2(d) shall continue to apply until such 61st day
                  (or such later date, as determined by the Holder, as may be
                  specified in such notice of waiver).

            e) Mechanics of Exercise.

                        i. Authorization of Warrant Shares. The Company
                  covenants that all Warrant Shares which may be issued upon the
                  exercise of the purchase rights represented by this Warrant
                  will, upon exercise of the purchase rights represented by this
                  Warrant, be duly authorized, validly issued, fully paid and
                  nonassessable and free from all taxes, liens and

                                       3

<PAGE>

                  charges in respect of the issue thereof (other than taxes in
                  respect of any transfer occurring contemporaneously with such
                  issue).

                        ii. Delivery of Certificates Upon Exercise. Certificates
                  for shares purchased hereunder shall be transmitted by the
                  transfer agent of the Company to the Holder by crediting the
                  account of the Holder's prime broker with the Depository Trust
                  Company through its Deposit Withdrawal Agent Commission
                  ("DWAC") system if the Company is a participant in such
                  system, and otherwise by physical delivery to the address
                  specified by the Holder in the Notice of Exercise within 3
                  Trading Days from the delivery to the Company of the Notice of
                  Exercise Form, surrender of this Warrant and payment of the
                  aggregate Exercise Price as set forth above ("Warrant Share
                  Delivery Date"). This Warrant shall be deemed to have been
                  exercised on the date the Exercise Price is received by the
                  Company. The Warrant Shares shall be deemed to have been
                  issued, and Holder or any other person so designated to be
                  named therein shall be deemed to have become a holder of
                  record of such shares for all purposes, as of the date the
                  Warrant has been exercised by payment to the Company of the
                  Exercise Price and all taxes required to be paid by the
                  Holder, if any, pursuant to Section 2(e)(vii) prior to the
                  issuance of such shares, have been paid.

                        iii. Delivery of New Warrants Upon Exercise. If this
                  Warrant shall have been exercised in part, the Company shall,
                  at the time of delivery of the certificate or certificates
                  representing Warrant Shares, deliver to Holder a new Warrant
                  evidencing the rights of Holder to purchase the unpurchased
                  Warrant Shares called for by this Warrant, which new Warrant
                  shall in all other respects be identical with this Warrant.

                        iv. Rescission Rights. If the Company fails to cause its
                  transfer agent to transmit to the Holder a certificate or
                  certificates representing the Warrant Shares pursuant to this
                  Section 2(e)(iv) by the Warrant Share Delivery Date, then the
                  Holder will have the right to rescind such exercise.

                        v. Compensation for Buy-In on Failure to Timely Deliver
                  Certificates Upon Exercise. In addition to any other rights
                  available to the Holder, if the Company fails to cause its
                  transfer agent to transmit to the Holder a certificate or
                  certificates representing the Warrant Shares pursuant to an
                  exercise on or before the Warrant Share Delivery Date, and if
                  after such date the Holder is required by its broker to
                  purchase (in an open market transaction or otherwise) shares
                  of Common Stock to deliver in satisfaction of a sale by the
                  Holder of the Warrant Shares which the Holder anticipated
                  receiving upon such exercise (a "Buy-In"), then the Company
                  shall (1) pay in cash to the Holder the amount by which (x)
                  the Holder's total purchase price (including brokerage
                  commissions, if any) for the shares of Common Stock so
                  purchased exceeds (y) the amount

                                       4

<PAGE>

                  obtained by multiplying (A) the number of Warrant Shares that
                  the Company was required to deliver to the Holder in
                  connection with the exercise at issue times (B) the price at
                  which the sell order giving rise to such purchase obligation
                  was executed, and (2) at the option of the Holder, either
                  reinstate the portion of the Warrant and equivalent number of
                  Warrant Shares for which such exercise was not honored or
                  deliver to the Holder the number of shares of Common Stock
                  that would have been issued had the Company timely complied
                  with its exercise and delivery obligations hereunder. For
                  example, if the Holder purchases Common Stock having a total
                  purchase price of $11,000 to cover a Buy-In with respect to an
                  attempted exercise of shares of Common Stock with an aggregate
                  sale price giving rise to such purchase obligation of $10,000,
                  under clause (1) of the immediately preceding sentence the
                  Company shall be required to pay the Holder $1,000. The Holder
                  shall provide the Company written notice indicating the
                  amounts payable to the Holder in respect of the Buy-In,
                  together with applicable confirmations and other evidence
                  reasonably requested by the Company. Nothing herein shall
                  limit a Holder's right to pursue any other remedies available
                  to it hereunder, at law or in equity including, without
                  limitation, a decree of specific performance and/or injunctive
                  relief with respect to the Company's failure to timely deliver
                  certificates representing shares of Common Stock upon exercise
                  of the Warrant as required pursuant to the terms hereof.

                        vi. No Fractional Shares or Scrip. No fractional shares
                  or scrip representing fractional shares shall be issued upon
                  the exercise of this Warrant. As to any fraction of a share
                  which Holder would otherwise be entitled to purchase upon such
                  exercise, the Company shall pay a cash adjustment in respect
                  of such final fraction in an amount equal to such fraction
                  multiplied by the Exercise Price.

                        vii. Charges, Taxes and Expenses. Issuance of
                  certificates for Warrant Shares shall be made without charge
                  to the Holder for any issue or transfer tax or other
                  incidental expense in respect of the issuance of such
                  certificate, all of which taxes and expenses shall be paid by
                  the Company, and such certificates shall be issued in the name
                  of the Holder or in such name or names as may be directed by
                  the Holder; provided, however, that in the event certificates
                  for Warrant Shares are to be issued in a name other than the
                  name of the Holder, this Warrant when surrendered for exercise
                  shall be accompanied by the Assignment Form attached hereto
                  duly executed by the Holder; and the Company may require, as a
                  condition thereto, the payment of a sum sufficient to
                  reimburse it for any transfer tax incidental thereto.

                        viii. Closing of Books. The Company will not close its
                  stockholder books or records in any manner which prevents the
                  timely exercise of this Warrant, pursuant to the terms hereof,
                  unless required by applicable law.

                                       5

      Section 3. Certain Adjustments.

            a) Stock Dividends and Splits. If the Company, at any time while
      this Warrant is outstanding: (A) pays a stock dividend or otherwise make a
      distribution or distributions on shares of its Common Stock or any other
      equity or equity equivalent securities payable in shares of Common Stock
      (which, for avoidance of doubt, shall not include any shares of Common
      Stock issued by the Company pursuant to this Warrant), (B) subdivides
      outstanding shares of Common Stock into a larger number of shares, (C)
      combines (including by way of reverse stock split) outstanding shares of
      Common Stock into a smaller number of shares, or (D) issues by
      reclassification of shares of the Common Stock any shares of capital stock
      of the Company, then in each case the Exercise Price shall be multiplied
      by a fraction of which the numerator shall be the number of shares of
      Common Stock (excluding treasury shares, if any) outstanding before such
      event and of which the denominator shall be the number of shares of Common
      Stock outstanding after such event and the number of shares issuable upon
      exercise of this Warrant shall be proportionately adjusted. Any adjustment
      made pursuant to this Section 3(a) shall become effective immediately
      after the record date for the determination of stockholders entitled to
      receive such dividend or distribution and shall become effective
      immediately after the effective date in the case of a subdivision,
      combination or re-classification.

            b) Subsequent Equity Sales. If the Company or any Subsidiary
      thereof, as applicable, at any time while this Warrant is outstanding,
      shall offer, sell, grant any option to purchase or offer, sell or grant
      any right to reprice its securities, or otherwise dispose of or issue (or
      announce any offer, sale, grant or any option to purchase or other
      disposition) any Common Stock or Common Stock Equivalents entitling any
      Person to acquire shares of Common Stock, at an effective price per share
      less than the then Exercise Price (such lower price, the "Base Share
      Price" and such issuances collectively, a "Dilutive Issuance"), as
      adjusted hereunder (if the holder of the Common Stock or Common Stock
      Equivalents so issued shall at any time, whether by operation of purchase
      price adjustments, reset provisions, floating conversion, exercise or
      exchange prices or otherwise, or due to warrants, options or rights per
      share which is issued in connection with such issuance, be entitled to
      receive shares of Common Stock at an effective price per share which is
      less than the Exercise Price, such issuance shall be deemed to have
      occurred for less than the Exercise Price), then, then, the Exercise Price
      shall be reduced by multiplying the Exercise Price by a fraction, the
      numerator of which is the number of shares of Common Stock issued and
      outstanding immediately prior to the Dilutive Issuance plus the number of
      shares of Common Stock which the aggregate consideration received or
      receivable by the Company in connection with such Dilutive Issuance would
      purchase at the then effective Exercise Price, and the denominator of
      which shall be the sum of the number of shares of Common Stock issued and
      outstanding immediately prior to the Dilutive Issuance plus the number of
      shares of Common Stock so issued or issuable in connection with the
      Dilutive Issuance and the number of Warrant Shares issuable hereunder
      shall be increased such that the aggregate Exercise Price payable
      hereunder, after taking into account the decrease in the Exercise Price,
      shall be equal to the aggregate Exercise Price prior to such adjustment.
      Such adjustment shall be made whenever such Common Stock or Common Stock
      Equivalents are issued. The Company

      shall notify the Holder in writing, no later than the Trading Day
      following the issuance of any Common Stock or Common Stock Equivalents
      subject to this section, indicating therein the applicable issuance price,
      or of applicable reset price, exchange price, conversion price and other
      pricing terms (such notice the "Dilutive Issuance Notice"). For purposes
      of clarification, whether or not the Company provides a Dilutive Issuance
      Notice pursuant to this Section 3(b), upon the occurrence of any Dilutive
      Issuance, after the date of such Dilutive Issuance the Holder is entitled
      to receive a number of Warrant Shares based upon the Base Share Price
      regardless of whether the Holder accurately refers to the Base Share Price
      in the Notice of Exercise.

            c) Pro Rata Distributions. If the Company, at any time prior to the
      Termination Date, shall distribute to all holders of Common Stock (and not
      to Holders of the Warrants) evidences of its indebtedness or assets or
      rights or warrants to subscribe for or purchase any security other than
      the Common Stock (which shall be subject to Section 3(b)), then in each
      such case the Exercise Price shall be adjusted by multiplying the Exercise
      Price in effect immediately prior to the record date fixed for
      determination of stockholders entitled to receive such distribution by a
      fraction of which the denominator shall be the VWAP determined as of the
      record date mentioned above, and of which the numerator shall be such VWAP
      on such record date less the then per share fair market value at such
      record date of the portion of such assets or evidence of indebtedness so
      distributed applicable to one outstanding share of the Common Stock as
      determined by the Board of Directors in good faith. In either case the
      adjustments shall be described in a statement provided to the Holders of
      the portion of assets or evidences of indebtedness so distributed or such
      subscription rights applicable to one share of Common Stock. Such
      adjustment shall be made whenever any such distribution is made and shall
      become effective immediately after the record date mentioned above.

            d) Fundamental Transaction. If, at any time while this Warrant is
      outstanding, (A) the Company effects any merger or consolidation of the
      Company with or into another Person, (B) the Company effects any sale of
      all or substantially all of its assets in one or a series of related
      transactions, (C) any tender offer or exchange offer (whether by the
      Company or another Person) is completed pursuant to which holders of
      Common Stock are permitted to tender or exchange their shares for other
      securities, cash or property, or (D) the Company effects any
      reclassification of the Common Stock or any compulsory share exchange
      pursuant to which the Common Stock is effectively converted into or
      exchanged for other securities, cash or property (in any such case, a
      "Fundamental Transaction"), then, upon any subsequent exercise of this
      Warrant, the Holder shall have the right to receive, for each Warrant
      Share that would have been issuable upon such exercise immediately prior
      to the occurrence of such Fundamental Transaction, at the option of the
      Holder, (a) upon exercise of this Warrant, the number of shares of Common
      Stock of the successor or acquiring corporation or of the Company, if it
      is the surviving corporation, and any additional consideration (the
      "Alternate Consideration") receivable upon or as a result of such
      reorganization, reclassification, merger, consolidation or disposition of
      assets by a Holder of the number of shares of Common Stock for which this
      Warrant is exercisable immediately prior to such event or (b) if the
      Company is acquired in an all cash transaction, cash equal to the value of
      this Warrant as determined in accordance with the Black-Scholes option
      pricing formula. For

                                       7

<PAGE>

      purposes of any such exercise, the determination of the Exercise Price
      shall be appropriately adjusted to apply to such Alternate Consideration
      based on the amount of Alternate Consideration issuable in respect of one
      share of Common Stock in such Fundamental Transaction, and the Company
      shall apportion the Exercise Price among the Alternate Consideration in a
      reasonable manner reflecting the relative value of any different
      components of the Alternate Consideration. If holders of Common Stock are
      given any choice as to the securities, cash or property to be received in
      a Fundamental Transaction, then the Holder shall be given the same choice
      as to the Alternate Consideration it receives upon any exercise of this
      Warrant following such Fundamental Transaction. To the extent necessary to
      effectuate the foregoing provisions, any successor to the Company or
      surviving entity in such Fundamental Transaction shall issue to the Holder
      a new warrant consistent with the foregoing provisions and evidencing the
      Holder's right to exercise such warrant into Alternate Consideration. The
      terms of any agreement pursuant to which a Fundamental Transaction is
      effected shall include terms requiring any such successor or surviving
      entity to comply with the provisions of this Section 3(d) and insuring
      that this Warrant (or any such replacement security) will be similarly
      adjusted upon any subsequent transaction analogous to a Fundamental
      Transaction.

            e) Exempt Issuance. Notwithstanding the foregoing, no adjustments,
      Alternate Consideration nor notices shall be made, paid or issued under
      this Section 3 in respect of an Exempt Issuance.

            f) Calculations. All calculations under this Section 3 shall be made
      to the nearest cent or the nearest 1/100th of a share, as the case may be.
      For purposes of this Section 3, the number of shares of Common Stock
      deemed to be issued and outstanding as of a given date shall be the sum of
      the number of shares of Common Stock (excluding treasury shares, if any)
      issued and outstanding.

            g) Voluntary Adjustment By Company. The Company may at any time
      during the term of this Warrant reduce the then current Exercise Price to
      any amount and for any period of time deemed appropriate by the Board of
      Directors of the Company.

            h) Notice to Holders.

                        i. Adjustment to Exercise Price. Whenever the Exercise
                  Price is adjusted pursuant to this Section 3, the Company
                  shall promptly mail to each Holder a notice setting forth the
                  Exercise Price after such adjustment and setting forth a brief
                  statement of the facts requiring such adjustment. If the
                  Company issues a variable rate security, despite the
                  prohibition thereon in the Purchase Agreement, the Company
                  shall be deemed to have issued Common Stock or Common Stock
                  Equivalents at the lowest possible conversion or exercise
                  price at which such securities may be converted or exercised
                  in the case of a Variable Rate Transaction (as defined in the
                  Purchase Agreement), or the lowest possible adjustment price
                  in the case of an MFN Transaction (as defined in the Purchase
                  Agreement.

                        ii. Notice to Allow Exercise by Holder. If (A) the
                  Company shall declare a dividend (or any other distribution)
                  on the Common Stock; (B) the Company shall declare a special
                  nonrecurring cash dividend on or a redemption of the Common
                  Stock; (C) the Company shall authorize the granting to all
                  holders of the Common Stock rights or warrants to subscribe
                  for or purchase any shares of capital stock of any class or of
                  any rights; (D) the approval of any stockholders of the
                  Company shall be required in connection with any
                  reclassification of the Common Stock, any consolidation or
                  merger to which the Company is a party, any sale or transfer
                  of all or substantially all of the assets of the Company, of
                  any compulsory share exchange whereby the Common Stock is
                  converted into other securities, cash or property; (E) the
                  Company shall authorize the voluntary or involuntary
                  dissolution, liquidation or winding up of the affairs of the
                  Company; then, in each case, the Company shall cause to be
                  mailed to the Holder at its last addresses as it shall appear
                  upon the Warrant Register of the Company, at least 5 Trading
                  Days prior to the applicable record or effective date
                  hereinafter specified (or, if greater, such number of days
                  prior notice as the Company provides to its Common Stock
                  holders), a notice stating (x) the date on which a record is
                  to be taken for the purpose of such dividend, distribution,
                  redemption, rights or warrants, or if a record is not to be
                  taken, the date as of which the holders of the Common Stock of
                  record to be entitled to such dividend, distributions,
                  redemption, rights or warrants are to be determined or (y) the
                  date on which such reclassification, consolidation, merger,
                  sale, transfer or share exchange is expected to become
                  effective or close, and the date as of which it is expected
                  that holders of the Common Stock of record shall be entitled
                  to exchange their shares of the Common Stock for securities,
                  cash or other property deliverable upon such reclassification,
                  consolidation, merger, sale, transfer or share exchange;
                  provided, that the failure to mail such notice or any defect
                  therein or in the mailing thereof shall not affect the
                  validity of the corporate action required to be specified in
                  such notice. The Holder is entitled to exercise this Warrant
                  during the 5-Trading Day period commencing on the date of such
                  notice to the effective date of the event triggering such
                  notice.

      Section 4. Transfer of Warrant.

            a) Transferability. Subject to compliance with any applicable
      securities laws and the conditions set forth in Sections 5(a) and 4(d)
      hereof and to the provisions of Section 4.1 of the Purchase Agreement,
      this Warrant and all rights hereunder are transferable, in whole or in
      part, upon surrender of this Warrant at the principal office of the
      Company, together with a written assignment of this Warrant substantially
      in the form attached hereto duly executed by the Holder or its agent or
      attorney and funds sufficient to pay any transfer taxes payable upon the
      making of such transfer. Upon such surrender and, if required, such
      payment, the Company shall execute and deliver a new Warrant or Warrants
      in the name of the assignee or assignees and in the denomination or
      denominations specified in such instrument of assignment, and shall issue
      to the assignor

                                       9

<PAGE>

      a new Warrant evidencing the portion of this Warrant not so assigned, and
      this Warrant shall promptly be cancelled. A Warrant, if properly assigned,
      may be exercised by a new holder for the purchase of Warrant Shares
      without having a new Warrant issued.

            b) New Warrants. This Warrant may be divided or combined with other
      Warrants upon presentation hereof at the aforesaid office of the Company,
      together with a written notice specifying the names and denominations in
      which new Warrants are to be issued, signed by the Holder or its agent or
      attorney. Subject to compliance with Section 4(a), as to any transfer
      which may be involved in such division or combination, the Company shall
      execute and deliver a new Warrant or Warrants in exchange for the Warrant
      or Warrants to be divided or combined in accordance with such notice.

            c) Warrant Register. The Company shall register this Warrant, upon
      records to be maintained by the Company for that purpose (the "Warrant
      Register"), in the name of the record Holder hereof from time to time. The
      Company may deem and treat the registered Holder of this Warrant as the
      absolute owner hereof for the purpose of any exercise hereof or any
      distribution to the Holder, and for all other purposes, absent actual
      notice to the contrary.

            d) Transfer Restrictions. If, at the time of the surrender of this
      Warrant in connection with any transfer of this Warrant, the transfer of
      this Warrant shall not be registered pursuant to an effective registration
      statement under the Securities Act and under applicable state securities
      or blue sky laws, the Company may require, as a condition of allowing such
      transfer (i) that the Holder or transferee of this Warrant, as the case
      may be, furnish to the Company a written opinion of counsel (which opinion
      shall be in form, substance and scope customary for opinions of counsel in
      comparable transactions) to the effect that such transfer may be made
      without registration under the Securities Act and under applicable state
      securities or blue sky laws, (ii) that the holder or transferee execute
      and deliver to the Company an investment letter in form and substance
      acceptable to the Company and (iii) that the transferee be an "accredited
      investor" as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7), or (a)(8)
      promulgated under the Securities Act or a qualified institutional buyer as
      defined in Rule 144A(a) under the Securities Act.

      Section 5. Miscellaneous.

            a) Title to Warrant. Prior to the Termination Date and subject to
      compliance with applicable laws and Section 4 of this Warrant, this
      Warrant and all rights hereunder are transferable, in whole or in part, at
      the office or agency of the Company by the Holder in person or by duly
      authorized attorney, upon surrender of this Warrant together with the
      Assignment Form annexed hereto properly endorsed. The transferee shall
      sign an investment letter in form and substance reasonably satisfactory to
      the Company.

            b) No Rights as Shareholder Until Exercise. This Warrant does not
      entitle the Holder to any voting rights or other rights as a shareholder
      of the Company prior to the exercise hereof. Upon the surrender of this
      Warrant and the payment of the aggregate Exercise Price (or by means of a
      cashless exercise), the Warrant Shares so purchased

                                       10

<PAGE>

      shall be and be deemed to be issued to such Holder as the record owner of
      such shares as of the close of business on the later of the date of such
      surrender or payment.

            c) Loss, Theft, Destruction or Mutilation of Warrant. The Company
      covenants that upon receipt by the Company of evidence reasonably
      satisfactory to it of the loss, theft, destruction or mutilation of this
      Warrant or any stock certificate relating to the Warrant Shares, and in
      case of loss, theft or destruction, of indemnity or security reasonably
      satisfactory to it (which, in the case of the Warrant, shall not include
      the posting of any bond), and upon surrender and cancellation of such
      Warrant or stock certificate, if mutilated, the Company will make and
      deliver a new Warrant or stock certificate of like tenor and dated as of
      such cancellation, in lieu of such Warrant or stock certificate.

            d) Saturdays, Sundays, Holidays, etc. If the last or appointed day
      for the taking of any action or the expiration of any right required or
      granted herein shall be a Saturday, Sunday or a legal holiday, then such
      action may be taken or such right may be exercised on the next succeeding
      day not a Saturday, Sunday or legal holiday.

            e) Authorized Shares.

                  The Company covenants that during the period the Warrant is
            outstanding, it will reserve from its authorized and unissued Common
            Stock a sufficient number of shares to provide for the issuance of
            the Warrant Shares upon the exercise of any purchase rights under
            this Warrant. The Company further covenants that its issuance of
            this Warrant shall constitute full authority to its officers who are
            charged with the duty of executing stock certificates to execute and
            issue the necessary certificates for the Warrant Shares upon the
            exercise of the purchase rights under this Warrant. The Company will
            take all such reasonable action as may be necessary to assure that
            such Warrant Shares may be issued as provided herein without
            violation of any applicable law or regulation, or of any
            requirements of the Trading Market upon which the Common Stock may
            be listed.

                  Except and to the extent as waived or consented to by the
            Holder, the Company shall not by any action, including, without
            limitation, amending its certificate of incorporation or through any
            reorganization, transfer of assets, consolidation, merger,
            dissolution, issue or sale of securities or any other voluntary
            action, avoid or seek to avoid the observance or performance of any
            of the terms of this Warrant, but will at all times in good faith
            assist in the carrying out of all such terms and in the taking of
            all such actions as may be necessary or appropriate to protect the
            rights of Holder as set forth in this Warrant against impairment.
            Without limiting the generality of the foregoing, the Company will
            (a) not increase the par value of any Warrant Shares above the
            amount payable therefor upon such exercise immediately prior to such
            increase in par value, (b) take all such action as may be necessary
            or appropriate in order that the Company may validly and legally
            issue fully paid and nonassessable Warrant Shares upon the exercise
            of this Warrant, and (c) use commercially reasonable efforts to
            obtain

                                       11

<PAGE>

            all such authorizations, exemptions or consents from any public
            regulatory body having jurisdiction thereof as may be necessary to
            enable the Company to perform its obligations under this Warrant.

                  Before taking any action which would result in an adjustment
            in the number of Warrant Shares for which this Warrant is
            exercisable or in the Exercise Price, the Company shall obtain all
            such authorizations or exemptions thereof, or consents thereto, as
            may be necessary from any public regulatory body or bodies having
            jurisdiction thereof.

            f) Jurisdiction. All questions concerning the construction,
      validity, enforcement and interpretation of this Warrant shall be
      determined in accordance with the provisions of the Purchase Agreement.

            g) Restrictions. The Holder acknowledges that the Warrant Shares
      acquired upon the exercise of this Warrant, if not registered, will have
      restrictions upon resale imposed by state and federal securities laws.

            h) Nonwaiver and Expenses. No course of dealing or any delay or
      failure to exercise any right hereunder on the part of Holder shall
      operate as a waiver of such right or otherwise prejudice Holder's rights,
      powers or remedies, notwithstanding the fact that all rights hereunder
      terminate on the Termination Date. If the Company willfully and knowingly
      fails to comply with any provision of this Warrant, which results in any
      material damages to the Holder, the Company shall pay to Holder such
      amounts as shall be sufficient to cover any costs and expenses including,
      but not limited to, reasonable attorneys' fees, including those of
      appellate proceedings, incurred by Holder in collecting any amounts due
      pursuant hereto or in otherwise enforcing any of its rights, powers or
      remedies hereunder.

            i) Notices. Any notice, request or other document required or
      permitted to be given or delivered to the Holder by the Company shall be
      delivered in accordance with the notice provisions of the Purchase
      Agreement.

            j) Limitation of Liability. No provision hereof, in the absence of
      any affirmative action by Holder to exercise this Warrant or purchase
      Warrant Shares, and no enumeration herein of the rights or privileges of
      Holder, shall give rise to any liability of Holder for the purchase price
      of any Common Stock or as a stockholder of the Company, whether such
      liability is asserted by the Company or by creditors of the Company.

            k) Remedies. Holder, in addition to being entitled to exercise all
      rights granted by law, including recovery of damages, will be entitled to
      specific performance of its rights under this Warrant. The Company agrees
      that monetary damages would not be adequate compensation for any loss
      incurred by reason of a breach by it of the provisions of this Warrant and
      hereby agrees to waive the defense in any action for specific performance
      that a remedy at law would be adequate.

            l) Successors and Assigns. Subject to applicable securities laws,
      this Warrant and the rights and obligations evidenced hereby shall inure
      to the benefit of and

                                       12

<PAGE>

      be binding upon the successors of the Company and the successors and
      permitted assigns of Holder. The provisions of this Warrant are intended
      to be for the benefit of all Holders from time to time of this Warrant and
      shall be enforceable by any such Holder or holder of Warrant Shares.

            m) Amendment. This Warrant may be modified or amended or the
      provisions hereof waived with the written consent of the Company and the
      Holder.

            n) Severability. Wherever possible, each provision of this Warrant
      shall be interpreted in such manner as to be effective and valid under
      applicable law, but if any provision of this Warrant shall be prohibited
      by or invalid under applicable law, such provision shall be ineffective to
      the extent of such prohibition or invalidity, without invalidating the
      remainder of such provisions or the remaining provisions of this Warrant.

            o) Headings. The headings used in this Warrant are for the
      convenience of reference only and shall not, for any purpose, be deemed a
      part of this Warrant.

                               NOTICE OF EXERCISE

To: PDG Environmental, Inc.

            (1) The undersigned hereby elects to purchase ________ Warrant
Shares of the Company pursuant to the terms of the attached Warrant (only if

                          REGISTRATION RIGHTS AGREEMENT

      This REGISTRATION RIGHTS AGREEMENT (this "AGREEMENT"), dated as of July
1, 2005, is made by and among PDG Environmental, Inc., a corporation organized
under the laws of the State of Delaware (the "COMPANY"), and the undersigned
(together with their affiliates, the "INITIAL INVESTORS").

                                   BACKGROUND

      A. In connection with that certain Securities Purchase Agreement of even
date herewith by and among the Company and the Initial Investors (the
"SECURITIES PURCHASE AGREEMENT"), the Company has agreed, upon the terms and
subject to the conditions contained therein, to issue and sell to the Initial
Investors (i) shares of the Company's Series C Convertible Preferred Stock, par
value $0.01 per share (the "INITIAL PREFERRED STOCK"), that are convertible into
shares of the Company's common stock, par value $0.02 per share (the "COMMON
STOCK"), upon the terms and subject to the limitations and conditions set forth
in the Certificate of Designation, Rights and Preferences with respect to such
Preferred Stock (the "CERTIFICATE OF DESIGNATION"), (ii) warrants ("INITIAL
WARRANTS") to acquire shares of Common Stock and (iii) warrants (the "PREFERRED
WARRANTS") to acquire additional shares of the Company's Series C Convertible
Preferred Stock, par value $0.01 per share (the "ADDITIONAL PREFERRED STOCK"
and, together with the Initial Preferred Stock, the "PREFERRED STOCK") and
additional warrants to acquire shares of Common Stock (the "ADDITIONAL WARRANTS"
and, together with the Initial Warrants, the "WARRANTS"). The shares of Common
Stock issuable upon conversion of or otherwise pursuant to the Preferred Stock
(without giving effect to the limitations in Article XV of the Certificate of
Designation) are referred to herein as the "CONVERSION SHARES" and the shares of
Common Stock issuable upon exercise of or otherwise pursuant to the Warrants
(without giving effect to the limitations in Section 10 of the Warrants) are
referred to herein as the "WARRANT SHARES."

      B. To induce the Initial Investors to execute and deliver the Securities
Purchase Agreement, and to consummate the transactions contemplated thereby, the
Company has agreed to provide certain registration rights under the Securities
Act of 1933, as amended, and the rules and regulations thereunder, or any
similar successor statute (collectively, the "SECURITIES ACT"), and applicable
state securities laws.

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

1.    DEFINITIONS.

      (a) As used in this Agreement, the following terms shall have the
following meanings:

<PAGE>

            (i) "INVESTOR" means the Initial Investors and any holders of
Registrable Securities to whom the rights conferred by this Agreement have been
duly and validly transferred in accordance with Section 9 hereof.

            (ii) "REGISTER," "REGISTERED," and "REGISTRATION" refer to a
registration effected by preparing and filing a Registration Statement or
Statements in compliance with the Securities Act and pursuant to Rule 415 under
the Securities Act or any successor rule providing for offering securities on a
continuous basis ("RULE 415"), and the declaration or ordering of effectiveness
of such Registration Statement by the United States Securities and Exchange
Commission (the "SEC").

            (iii) "REGISTRABLE SECURITIES" means (a) the Conversion Shares, (b)
the Warrant Shares, and (c) any shares of capital stock issued or issuable, from
time to time, as a distribution on or in exchange for or otherwise with respect
to any of the foregoing (including the Preferred Stock, the Preferred Warrants
and the Warrants), whether as default payments, Premium (as defined in the
Certificate of Designation), on account of the reset adjustment set forth in
Article I.D of the Certificate of Designation, anti-dilution or other
adjustments or otherwise; provided, however, that any such securities shall
cease to be Registrable Securities when (i) such Registrable Securities have
been sold or (ii) such Registrable Securities may be sold without registration
or restriction pursuant to Rule 144(k) under the Securities Act or any successor
provision.

            (iv) "REGISTRATION STATEMENT" means a registration statement of the
Company under the Securities Act that covers the Registrable Securities pursuant
to this Agreement, including the prospectus contained therein and any and all
pre- and post-effective amendments and any and all exhibits thereto and
documents incorporated by reference therein.

      (b) Capitalized terms used herein and not otherwise defined herein shall
have the respective meanings set forth in the Securities Purchase Agreement.

2.    REGISTRATION.

      (a) Mandatory Registration. The Company shall prepare promptly and file
with the SEC as soon as practicable, but in no event later than the ninetieth
(90th) day following the date hereof (the "FILING DATE"), a Registration
Statement on Form S-2 (or, if Form S-2 is not then available, on such form of
Registration Statement as is then available to effect a registration of all of
the Registrable Securities, subject to the consent of the Initial Investors)
covering the resale of at least nine million, thirty-three thousand, seven
hundred and fifty (9,033,750) Registrable Securities. The Registration Statement
filed hereunder, to the extent allowable under the Securities Act and the Rules
promulgated thereunder (including Rule 416), shall state that such Registration
Statement also covers such indeterminate number of additional shares of Common
Stock as may become issuable upon conversion of the Preferred Stock and exercise
of the Warrants to prevent dilution resulting from stock splits, stock dividends
or similar transactions. The Registrable Securities included on the Registration
Statement shall be allocated among the Investors as set forth in Section 11(k)
hereof. The Registration Statement (and each amendment

                                      -2-
<PAGE>

or supplement thereto, and each request for acceleration of effectiveness
thereof) shall be provided to (and subject to the approval of) the Initial
Investors and their counsel prior to its filing or other submission.

      (b) Payments by the Company. The Company shall use its best efforts to
cause the Registration Statement required to be filed pursuant to Section 2(a)
hereof to become effective as soon as practicable, but in no event later than
the one hundred forty-fifth (145th) day following the date hereof (the
"REGISTRATION DEADLINE"). At the time of effectiveness, the Company shall ensure
that such Registration Statement covers at least one hundred and twenty-five
percent (125%) of the Registrable Securities, including, if necessary, by filing
an amendment prior to the effective date of the Registration Statement to
increase the number of Registrable Securities covered thereby. If (i) (A) the
Registration Statement required to be filed pursuant to Section 2(a) hereof is
not filed with the SEC prior to the Filing Date or declared effective by the SEC
on or before the Registration Deadline or (B) any Registration Statement
required to be filed pursuant to Section 3(d) hereof is not declared effective
by the SEC on or before the ninetieth (90th) day following the applicable
Registration Trigger Date (as defined in Section 3(d) below), (ii) if, after any
such Registration Statement has been declared effective by the SEC and until the
expiration of the Registration Period (as defined below), sales of any of the
Registrable Securities required to be covered by such Registration Statement
(including any Registrable Securities required to be registered pursuant to
Section 3(d) hereof) cannot be made pursuant to such Registration Statement by
reason of a stop order or the Company's failure to update the Registration
Statement or for any other reason outside the control of the Investors (subject
to the right of the Company to suspend use thereof during a Black-Out Period (as
defined in Section 4(c) below) not to exceed forty-five (45) consecutive days or
seventy-five (75) days in any 12-month period (each such period being a
"PERMITTED BLACK-OUT PERIOD"); provided, however, that the duration of any
Permitted Black-Out Period resulting solely from a request by an Investor
pursuant to Section 3(o) shall not be considered for purposes of calculating the
forty-five (45) or seventy-five (75) day limits described in this proviso), or
(iii) the Common Stock is not listed or included for quotation on the Nasdaq
SmallCap Market (the "SMALLCAP MARKET"), the Nasdaq National Market (the
"NATIONAL MARKET"), the New York Stock Exchange (the "NYSE"), the American Stock
Exchange (the "AMEX") or the OTC Electronic Bulletin Board (the "BULLETIN
BOARD") at any time after the Registration Deadline hereunder, then the Company
will make payments to each Investor in such amounts and at such times as shall
be determined pursuant to this Section 2(b) as partial relief for the damages to
the Investors by reason of any such delay in or reduction of their ability to
sell the Registrable Securities (which remedy shall not be exclusive of any
other remedies available at law or in equity). The Company shall pay to each
Investor an amount equal to the product of (i) the number of shares of Preferred
Stock then outstanding and held by such Investor (including, for this purpose,
any shares of Preferred Stock that have been converted into Conversion Shares
then held by such Investor as if such shares of Preferred Stock had not been so
converted) multiplied by the Purchase Price (as defined in the Securities
Purchase Agreement) plus any additional amounts paid in connection with the
exercise of Preferred Warrants by such Investor, multiplied by (ii) one
hundredth (0.01), for each 30 day period (or portion thereof) (A) after the
Filing Date and prior to the date the Registration Statement is filed with the
SEC pursuant to Section 2(a), (B) after the Registration Deadline and prior to
the date the Registration Statement filed pursuant to Section 2(a) is declared
effective by the SEC, (C) after the ninetieth (90th) day following a
Registration Trigger Date and prior to the date the Registration Statement filed
pursuant to Section 3(d) hereof is declared effective by

                                      -3-
<PAGE>

the SEC, or (D) during which sales of any Registrable Securities cannot be made
pursuant to any such Registration Statement after the Registration Statement has
been declared effective (other than with respect to any Permitted Black-Out
Period) or the Common Stock is not listed or included for quotation on the
SmallCap Market, the National Market, NYSE, AMEX or the Bulletin Board;
provided, however, that, for purpose of calculating the payment amount owed to
any given Investor, there shall be excluded from each such period any delays
which are solely attributable to changes required by such Investor in the
Registration Statement with respect to information relating to such Investor,
including, without limitation, changes to the plan of distribution (other than
any corrections of Company mistakes with respect to information previously
provided by such Investor). All such amounts required to be paid hereunder shall
be paid in cash within five days after the end of each period that gives rise to
such obligation, provided that, if any such period extends for more than thirty
(30) days, interim payments shall be made for each such 30 day period.

      (c) [Intentionally omitted]

      (d) Piggy-Back Registrations. If, at any time prior to the expiration of
the Registration Period (as defined in Section 3(b) below) the Company shall
file with the SEC a Registration Statement relating to an offering for its own
account or the account of others under the Securities Act of any of its equity
securities (other than on Form S-4 or Form S-8 or their then equivalents
relating to equity securities to be issued solely in connection with any
acquisition of any entity or business or equity securities issuable in
connection with stock option or other employee benefit plans), the Company shall
send to each Investor written notice of such filing, and if, within 15 days
after the date of such notice, such Investor shall so request in writing, the
Company shall include in such Registration Statement all or any part of the
Registrable Securities such Investor requests to be registered. Notwithstanding
the foregoing, in the event that, in connection with any underwritten public
offering, the managing underwriter(s) thereof shall impose a limitation on the
number of shares of Common Stock that may be included in the Registration
Statement because, in such underwriter(s)' judgment, marketing or other factors
dictate such limitation is necessary to facilitate public distribution, then the
Company shall be obligated to include in such Registration Statement only such
limited portion of the Registrable Securities with respect to which such
Investor has requested inclusion hereunder as the underwriter shall permit;
provided, however, that (i) the Company shall not exclude any Registrable
Securities unless the Company has first excluded all outstanding securities, the
holders of which are not contractually entitled to inclusion of such securities
in such Registration Statement or are not contractually entitled to pro rata
inclusion with the Registrable Securities, (ii) after giving effect to the
immediately preceding proviso, any such exclusion of Registrable Securities
shall be made pro rata among the Investors seeking to include Registrable
Securities and the holders of other securities having the contractual right to
inclusion of their securities in such Registration Statement by reason of demand
registration rights in proportion to the number of Registrable Securities or
other securities, as applicable, sought to be included by each such Investor or
other holder and (iii) no such reduction shall reduce the amount of Registrable
Securities included in the registration below twenty-five percent (25%) of the
total amount of

                                      -4-
<PAGE>

securities included in such registration. No right to registration of
Registrable Securities under this Section 2(d) shall be construed to limit any
registration required under Section 2(a) hereof. If an offering in connection
with which an Investor is entitled to registration under this Section 2(d) is an
underwritten offering, then each Investor whose Registrable Securities are
included in such Registration Statement shall, unless otherwise agreed by the
Company, offer and sell such Registrable Securities in an underwritten offering
using the same underwriter or underwriters and, subject to the provisions of
this Agreement, on the same terms and conditions as other shares of Common Stock
included in such underwritten offering. With respect to any registration of
Registrable Securities pursuant to this Section 2(d), if at any time after
written notice of its intention to register any securities and prior to the
effective date of the Registration Statement filed in connection with such
registration the Company shall determine for any reason either not to register
or delay registration of such securities, or to withdraw the Registration
Statement after filing and after notice thereof, but prior to the effectiveness
of the Registration Statement, the Company may, at its election, give written
notice of such determination to each Investor and thereupon (i) in the case of a
determination not to register, shall be relieved of its obligation to register
any Registrable Securities in connection with such registration pursuant to this
Section 2(d) and (ii) in the case of a determination to delay registering, shall
be permitted to delay registering any Registrable Securities pursuant to this
Section 2(d), for the same period as the delay in registering such other
securities.

      (e) Eligibility for Form S-2. The Company represents and warrants that it
meets the requirements for the use of Form S-2 for registration of the sale by
the Initial Investors and any other Investor of the Registrable Securities and
the Company shall file all reports and statements required to be filed by the
Company with the SEC in a timely manner so as to thereafter maintain such
eligibility for the use of Form S-2.

3.    OBLIGATIONS OF THE COMPANY.

      In connection with the registration of the Registrable Securities, the
Company shall have the following obligations:

      (a) The Company shall respond promptly to any and all comments made by the
staff of the SEC to any Registration Statement required to be filed hereunder,
and shall submit to the SEC, before the close of business on the second business
day immediately following the business day on which the Company learns (either
by telephone or in writing) that no review of such Registration Statement will
be made by the SEC or that the staff of the SEC has no further comments on such
Registration Statement, as the case may be, a request for acceleration of the
effectiveness of such Registration Statement to a time and date as soon as
practicable.

      (b) The Company shall keep such Registration Statement effective pursuant
to Rule 415 at all times (subject to the right of the Company to suspend use
thereof during any Permitted Black-Out Period) until such date as is the earlier
of (i) the date on which all of the Registrable Securities have been sold and
(ii) the date on which all of the Registrable Securities may be immediately sold
to the public without registration or restriction pursuant to Rule 144(k) under
the Securities Act or any successor provision (the "REGISTRATION PERIOD"), which
Registration

                                      -5-
<PAGE>

Statement (including any amendments or supplements thereto and prospectuses
contained therein and all documents incorporated by reference therein, and
subject to the right of the Company to suspend use thereof during any Permitted
Black-Out Period) (A) shall comply in all material respects with the
requirements of the Securities Act and the rules and regulations of the SEC
promulgated thereunder and (B) shall not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein, or
necessary to make the statements therein not misleading. The financial
statements of the Company included in any such Registration Statement or
incorporated by reference therein (x) shall comply as to form in all material
respects with the applicable accounting requirements and the published rules and
regulations of the SEC applicable with respect thereto, (y) shall be prepared in
accordance with U.S. generally accepted accounting principles, consistently
applied during the periods involved (except as may be otherwise indicated in
such financial statements or the notes thereto or, in the case of unaudited
interim statements, to the extent they may not include footnotes or may be
condensed on summary statements) and (z) fairly present in all material respects
the consolidated financial position of the Company and its consolidated
subsidiaries as of the dates thereof and the consolidated results of their
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to immaterial year-end adjustments).

      (c) The Company shall (i) prepare and file with the SEC such amendments
(including post-effective amendments) and supplements to any Registration
Statement required to be filed hereunder and the prospectus used in connection
with any such Registration Statement as may be necessary to keep such
Registration Statement effective at all times during the Registration Period
(subject to the right of the Company to suspend use thereof during any Permitted
Black-Out Period), and (ii) during the Registration Period, comply with the
provisions of the Securities Act with respect to the disposition of all
Registrable Securities of the Company covered by any such Registration
Statement.

      (d) In the event the number of shares available under a Registration
Statement filed pursuant to this Agreement is, for any five (5) consecutive
trading days (the last of such five (5) trading days being the "REGISTRATION
TRIGGER DATE"), insufficient to cover one hundred and twenty-five percent (125%)
of the Registrable Securities then issued or issuable upon conversion of the
Preferred Stock (without giving effect to any limitations on conversion
contained in the Certificate of Designation) and exercise of the Warrants
(without giving effect to any limitations on exercise contained in the
Warrants), the Company shall provide each Investor written notice of such
Registration Trigger Date within three (3) business days thereafter and shall
amend the Registration Statement, or file a new Registration Statement (on the
short form available therefor, if applicable), or both, so as to cover on the
amended Registration Statement and/or such new Registration Statement one
hundred and twenty-five percent (125%) of the Registrable Securities issued or
issuable upon conversion of the Preferred Stock (without giving effect to any
limitations on conversion contained in the Certificate of Designation) or
exercise of the Warrants (without giving effect to any limitations on exercise
contained in the Warrants) as of the Registration Trigger Date, in each case, as
soon as practicable, but in any event within fifteen (15) days after the
Registration Trigger Date. The Company shall cause such amendment(s) and/or new
Registration Statement(s) to become effective as soon as practicable following
the filing thereof. In the event the Company fails to obtain the effectiveness
of any such

                                      -6-
<PAGE>

Registration Statement within ninety (90) days after a Registration Trigger Date
(subject to the right of the Company to suspend effectiveness of the
Registration Statement or delay effectiveness of the new Registration Statement
during a Permitted Black-Out Period), each Investor shall thereafter have the
option, exercisable in whole or in part at any time and from time to time by
delivery of a written notice to the Company (a "MANDATORY REDEMPTION NOTICE"),
to require the Company to redeem for cash such number of the Investor's shares
of the Preferred Stock at a price per share of Preferred Stock equal to one
hundred and twenty percent (120%) of the Purchase Price (as defined in the
Securities Purchase Agreement) such that, following such redemption, the total
number of Registrable Securities included on the Registration Statement for
resale by such Investor is at least equal to one hundred and twenty-five percent
(125%) of the Registrable Securities issued or issuable upon conversion of such
Investor's Preferred Stock (without giving effect to any limitations on
conversion contained in the Certificate of Designation) and exercise of such
Investor's Warrants (without giving effect to any limitation on exercise
contained in the Warrants). If the Company fails to redeem any of such Preferred
Stock within five (5) business days after its receipt of a Mandatory Redemption
Notice, then such Investor shall be entitled to the remedies provided in Article
VIII of the Certificate of Designation.

      (e) The Company shall furnish to each Investor whose Registrable
Securities are included in a Registration Statement and such Investor's legal
counsel (i) promptly after the same is prepared and publicly distributed, filed
with the SEC or received by the Company, as applicable, one copy of the
Registration Statement and any amendment thereto, each preliminary prospectus
and prospectus and each amendment or supplement thereto, and, in the case of the
Registration Statement required to be filed pursuant to Section 2(a), each
letter written by or on behalf of the Company to the SEC or the staff of the SEC
(including, without limitation, any request to accelerate the effectiveness of
the Registration Statement or amendment thereto), and each item of written
correspondence from the SEC or the staff of the SEC, in each case relating to
the Registration Statement (other than any portion thereof that contains
information for which the Company has sought confidential treatment), (ii) on
the date of effectiveness of the Registration Statement or any amendment
thereto, a notice stating that the Registration Statement or amendment has been
declared effective, and (iii) such number of copies of a prospectus, including a
preliminary prospectus, all amendments and supplements thereto and all such
other documents as such Investor may reasonably request in order to facilitate
the disposition of the Registrable Securities owned by such Investor.

      (f) The Company shall use its best efforts to (i) register and qualify the
Registrable Securities covered by any Registration Statement under such other
securities or "blue sky" laws of such jurisdictions in the United States as each
Investor who holds Registrable Securities being offered reasonably requests,
(ii) prepare and file in those jurisdictions such amendments (including
post-effective amendments) and supplements to such registrations and
qualifications as may be necessary to maintain the effectiveness thereof during
the Registration Period, (iii) take such other actions as may be necessary to
maintain such registrations and qualifications in effect at all times during the
Registration Period, and (iv) take all other actions reasonably necessary or
advisable to qualify the Registrable Securities for sale in such jurisdictions;
provided, however, that the Company shall not be required in connection
therewith or as a

                                      -7-
<PAGE>

condition thereto to (A) qualify to do business in any jurisdiction where it
would not otherwise be required to qualify but for this Section 3(f), (B)
subject itself to general taxation in any such jurisdiction, (C) file a general
consent to service of process in any such jurisdiction, (D) provide any
undertakings that cause the Company undue expense or burden, or (E) make any
change in its Certificate of Incorporation or Bylaws, which in each case the
Board of Directors of the Company determines to be contrary to the best
interests of the Company and its stockholders.

      (g) As promptly as practicable after (i) becoming aware of any event, as a
result of which the prospectus included in any Registration Statement that
includes Registrable Securities, as then in effect, includes an untrue statement
of a material fact or omits to state a material fact required to be stated
therein or necessary to make the statements therein not misleading, or (ii)
determining that it shall be necessary to amend or supplement the prospectus
contained in the Registration Statement for any other reason in order to comply
with the Securities Act, then Company shall (x) notify each Investor by
telephone and facsimile of the happening of such event or of such other reason
and (y) promptly prepare a supplement or amendment to such Registration
Statement to correct such untrue statement or omission or effect such
compliance, and deliver such number of copies of such supplement or amendment to
each Investor as such Investor may reasonably request.

      (h) The Company shall use its best efforts (i) to prevent the issuance of
any stop order or other suspension of effectiveness of any Registration
Statement that includes Registrable Securities (subject to the right of the
Company to suspend use thereof during any Permitted Black-Out Period), and, if
such an order is issued, to obtain the withdrawal of such order at the earliest
practicable moment (including in each case by amending or supplementing such
Registration Statement), and (ii) to notify each Investor who holds Registrable
Securities being sold (or, in the event of an underwritten offering, the
managing underwriters) of the issuance of such order and the resolution thereof
(and if such Registration Statement is supplemented or amended, deliver such
number of copies of such supplement or amendment to each Investor as such
Investor may reasonably request).

      (i) The Company shall permit a single firm of counsel designated by the
Initial Investors to review any Registration Statement required to be filed
hereunder and all amendments and supplements thereto a reasonable period of time
prior to its filing with the SEC, and not file any document in a form to which
such counsel reasonably objects.

      (j) The Company shall make generally available to its security holders as
soon as practicable, but in no event later than 90 days after the close of the
period covered thereby, an earnings statement (in form complying with the
provisions of Rule 158 under the Securities Act) covering a twelve-month period
beginning not later than the first day of the Company's fiscal quarter next
following the effective date of the Registration Statement. The Company will be
deemed to have complied with its obligations under this Section 3(j) upon the
Company's filing, on an appropriate form, the appropriate report of the Company
as required by the Securities Exchange Act of 1934, as amended, and the rules
and regulations thereunder, or any similar successor statute (collectively, the
"EXCHANGE ACT").

                                      -8-
<PAGE>

      (k) The Company shall hold in confidence and not make any disclosure of
information concerning an Investor provided to the Company unless (i) disclosure
of such information is necessary to comply with federal or state securities
laws, (ii) the disclosure of such information is necessary to avoid or correct a
misstatement or omission in any Registration Statement that includes such
Investor's Registrable Securities, (iii) the release of such information is
ordered pursuant to a subpoena or other order from a court or governmental body
of competent jurisdiction, (iv) such information has been made generally
available to the public other than by disclosure in violation of this or any
other agreement, or (v) such Investor consents to the form and content of any
such disclosure. The Company shall, upon learning that disclosure of any
information concerning an Investor is sought in or by a court or governmental
body of competent jurisdiction or through other means, give prompt notice to
such Investor prior to making such disclosure, and cooperate with the Investor,
at the Investor's expense, in taking appropriate action to prevent disclosure
of, or to obtain a protective order for, such information.

      (l) The Company shall use its best efforts to promptly cause all of the
Registrable Securities covered by any Registration Statement to be listed or
designated for quotation on the SmallCap Market, the National Market, the NYSE,
the AMEX, the Bulletin Board or any other national securities exchange or
automated quotation system and on each additional national securities exchange
or automated quotation system on which securities of the same class or series
issued by the Company are then listed or quoted, if any, if the listing or
quotation of such Registrable Securities is then permitted under the rules of
such exchange or automated quotation system, and in any event, without limiting
the generality of the foregoing, to arrange for or maintain at least two market
makers to register with the National Association of Securities Dealers, Inc.
(the "NASD") as such with respect to the Registrable Securities.

      (m) The Company shall provide a transfer agent and registrar, which may be
a single entity, for the Registrable Securities not later than the effective
date of the Registration Statement required to be filed pursuant to Section 2(a)
hereof.

      (n) The Company shall cooperate with any Investor who holds Registrable
Securities being offered and the managing underwriter or underwriters, if any,
to facilitate the timely preparation and delivery of certificates (not bearing
any restrictive legends) representing Registrable Securities to be offered
pursuant to any Registration Statement and enable such certificates to be in
such denominations or amounts, as the case may be, and registered in such names,
as such Investor or the managing underwriter or underwriters, if any, may
reasonably request. Without limiting the generality of the foregoing, within
three business days after any Registration Statement that includes Registrable
Securities is declared effective by the SEC, the Company shall cause legal
counsel selected by the Company to deliver to the transfer agent for the
Registrable Securities (with copies to any Investor whose Registrable Securities
are included in such Registration Statement), an opinion of such counsel in the
form attached hereto as Exhibit A.

      (o) At the request of any Investor, the Company shall prepare and file
with the SEC such amendments (including post-effective amendments) and
supplements to any Registration Statement required to be filed hereunder and the
prospectus used in connection with such

                                      -9-
<PAGE>

Registration Statement as may be necessary in order to change the plan of
distribution set forth in such Registration Statement.

      (p) The Company shall comply with all applicable laws related to a
Registration Statement and offering and sale of securities and all applicable
rules and regulations of governmental authorities in connection therewith
(including, without limitation, the Securities Act and the Exchange Act and the
rules and regulations thereunder promulgated by the SEC).

      (q) From and after the date of this Agreement, the Company shall not, and
shall not agree to, allow the holders of any securities of the Company to
include any of their securities which are not Registrable Securities in the
Registration Statement required to be filed pursuant to Section 2(a) or 3(d)
hereof without the consent of the holders of a majority in interest of the
Registrable Securities, subject to the rights of certain investors pursuant to
that certain Registration Rights Agreement, dated as of on or about July 1,
2005, entered into by the Company in connection with the concurrent offering
contemplated by Section 7(g) of the Securities Purchase Agreement (the
"Concurrent Offering Registration Rights Agreement"); provided, however that
such Concurrent Offering Registration Rights Agreement, and any amendment
thereto, shall have been approved by the Investors, with such approval not to be
unreasonably withheld or delayed. The Company (x) shall not request that the SEC
declare the registration statement filed pursuant to the Concurrent Offering
Registration Rights Agreement (the "Concurrent Offering Registration Statement")
effective as of any date or time prior to the date and time on which the
Registration Statement shall become effective, and (y) shall otherwise cause the
Registration Statement to be first declared effective by the SEC no later than
such date and time as the Concurrent Offering Registration Statement shall be
first declared effective by the SEC, including, without limitation, by filing a
"delaying amendment" in respect of the Concurrent Offering Registration
Statement pursuant to Rule 473 under the Securities Act.

      (r) The Company shall make available for inspection by (i) each Investor,
(ii) any underwriter participating in any disposition pursuant to any
Registration Statement, (iii) one firm of attorneys and one firm of accountants
or other agents retained by the Investors, and (iv) one firm of attorneys
retained by all such underwriters (collectively, the "INSPECTORS") all pertinent
financial and other records, and pertinent corporate documents and properties of
the Company (collectively, the "RECORDS"), as shall be reasonably deemed
necessary by each Inspector to enable such Inspector to exercise its due
diligence responsibility, and cause the Company's officers, directors and
employees to supply all information which any Inspector may reasonably request
for purposes of such due diligence; provided, however, that each Inspector shall
hold in confidence and shall not make any disclosure (except to an Investor) of
any Record or other information which the Company determines in good faith to be
confidential, and of which determination the Inspectors are so notified, unless
(A) the disclosure of such Records is necessary to avoid or correct a
misstatement or omission in any Registration Statement, (B) the release of such
Records is ordered pursuant to a subpoena or other order from a court or
government body of competent jurisdiction, or (C) the information in such
Records has been made generally available to the public other than by disclosure
in violation of this or any other agreement. The Investors shall, upon learning
that disclosure of any information contained in such Records is sought in or by
a court or governmental body of competent jurisdiction or

                                      -10-
<PAGE>

through other means, give prompt notice, if and to the extent practicable under
the circumstances, to the Company prior to making such disclosure and cooperate
with the Company, at the Company's expense, in taking appropriate action to
prevent disclosure of, or to obtain a protective order for, such information.
Nothing herein shall be deemed to limit any Investor's ability to sell
Registrable Securities in a manner that is otherwise consistent with applicable
laws and regulations.

      (s) In the case of an underwritten public offering, at the request of any
Investor, the Company shall furnish, on the date of effectiveness of the
Registration Statement (i) an opinion, dated as of such date, from counsel
representing the Company addressed to any such Investor and in form, scope and
substance as is customarily given in an underwritten public offering and (ii) a
letter, dated such date, from the Company's independent certified public
accountants in form and substance as is customarily given by independent
certified public accountants to underwriters in an underwritten public offering,
addressed to the underwriters, if any, and any such Investor.

4.    OBLIGATIONS OF THE INVESTORS.

      In connection with the registration of the Registrable Securities, each
Investor shall have the following obligations:

      (a) It shall be a condition precedent to the obligations of the Company to
effect the registration pursuant to this Agreement with respect to the
Registrable Securities of a particular Investor that such Investor shall furnish
to the Company such information regarding itself, the Registrable Securities
held by it and the intended method of disposition of the Registrable Securities
held by it as shall be reasonably required to effect the registration of such
Registrable Securities and shall execute such documents in connection with such
registration as the Company may reasonably request. At least five trading days
prior to the first anticipated filing date of the Registration Statement, the
Company shall notify each Investor of the information the Company requires from
each such Investor. Each Investor shall promptly notify the Company in writing
of any changes in the information set forth in the Registration Statement after
it is prepared regarding the Investor or its plan of distribution to the extent
required by law.

      (b) Each Investor, by such Investor's acceptance of the Registrable
Securities, agrees to cooperate with the Company as reasonably requested by the
Company in connection with the preparation and filing of any Registration
Statement required to be filed hereunder (or any amendments or supplements
thereto), unless such Investor has notified the Company in writing of such
Investor's election to exclude all of such Investor's Registrable Securities
from such Registration Statement.

      (c) Upon receipt of any notice from the Company of the happening of any
event of the kind described in Section 3(g) or 3(h), or upon a request by the
Investor pursuant to Section 3(o) hereof, in each case with respect to any
Registration Statement including Registrable

                                      -11-
<PAGE>

Securities, each Investor shall immediately discontinue disposition of
Registrable Securities pursuant to such Registration Statement until such
Investor's receipt of the copies of the supplemented or amended prospectus
contemplated by Sections 3(g), 3(h) or 3(o) or until the Investor is advised in
writing by the Company that the use of the prospectus contained in the
Registration Statement may be resumed (such period being a "BLACK-OUT PERIOD"),
as applicable, and, if so directed by the Company, such Investor shall deliver
to the Company (at the expense of the Company) or destroy (and deliver to the
Company a certificate of destruction) all copies in such Investor's possession
of the prospectus covering such Registrable Securities current at the time of
receipt of such notice. Notwithstanding the foregoing or anything to the
contrary in this Agreement, but subject to compliance with applicable laws, the
Company shall cause the transfer agent for the Registrable Securities to deliver
unlegended shares of Common Stock to a transferee of an Investor in accordance
with the terms of the Preferred Stock and Warrants in connection with any sale
of Registrable Securities with respect to which any such Investor has entered
into a contract for sale prior to receipt of such notice and for which any such
Investor has not yet settled.

      (d) No Investor may participate in any underwritten distribution hereunder
unless such Investor (i) agrees to sell such Investor's Registrable Securities
on the basis provided in any underwriting arrangements in usual and customary
form entered into by the Company, (ii) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms of such underwriting
arrangements, (iii) agrees to pay its pro rata share of all underwriting
discounts and commissions and any expenses in excess of those payable by the
Company pursuant to Section 5 below, and (iv) complies with all applicable laws
in connection therewith. Notwithstanding anything in this Section 4(d) to the
contrary, this Section 4(d) is not intended to limit any Investor's rights under
Sections 2(a) or 3(d) hereof.

5.    EXPENSES OF REGISTRATION.

      All expenses incurred by the Company or the Investors in connection with
registrations, filings or qualifications pursuant to Sections 2 and 3 above
(including, without limitation, all registration, listing and qualification
fees, printers and accounting fees, the fees and disbursements of counsel for
the Company and the fees and disbursements of one counsel selected by the
Investors, and, in connection with any Investor's exercise of the piggy-back
registration rights provided for in Section 2(d) hereof, any underwriting
discounts and commissions) shall be borne by the Company. In addition, the
Company shall pay (on an as incurred basis) each Investor's costs and expenses
(including legal fees) incurred in connection with the enforcement of the rights
of such Investor hereunder.

6.    INDEMNIFICATION.

      In the event any Registrable Securities are included in a Registration
Statement under this Agreement:

                                      -12-
<PAGE>

      (a) To the extent permitted by law, the Company shall indemnify, hold
harmless and defend (i) each Investor who holds such Registrable Securities, and
(ii) the directors, officers, partners, members, employees and agents
(including, without limitation, legal counsel) of each such Investor and each
person, if any, who controls each such Investor within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act (each, an "INVESTOR
INDEMNIFIED PERSON"), against any joint or several losses, claims, damages,
liabilities or expenses (collectively, together with actions, proceedings or
inquiries by any regulatory or self-regulatory organization, whether commenced
or threatened, in respect thereof, "CLAIMS") to which any of them may become
subject insofar as such Claims arise out of or are based upon: (A) any untrue
statement or alleged untrue statement of a material fact in a Registration
Statement or the omission or alleged omission to state therein a material fact
required to be stated or necessary to make the statements therein not
misleading, (B) any untrue statement or alleged untrue statement of a material
fact contained in any preliminary prospectus if used prior to the effective date
of such Registration Statement, or contained in the final prospectus (as amended
or supplemented, if the Company files any amendment thereof or supplement
thereto with the SEC) or the omission or alleged omission to state therein any
material fact necessary to make the statements made therein, in light of the
circumstances under which the statements therein were made, not misleading, or
(C) any violation or alleged violation by the Company of the Securities Act, the
Exchange Act or any other law (including, without limitation, any state
securities law), rule or regulation relating to the offer or sale of the
Registrable Securities (the matters in the foregoing clauses (A) through (C),
collectively, "VIOLATIONS"). Subject to the restrictions set forth in Section
6(c) with respect to the number of legal counsel, the Company shall reimburse
each Investor and each other Investor Indemnified Person, promptly as such
expenses are incurred and are due and payable, for any reasonable legal fees or
other reasonable expenses incurred by them in connection with investigating or
defending any such Claim. Notwithstanding anything to the contrary contained
herein, the indemnification agreement contained in this Section 6(a): (x) shall
not apply to a Claim arising out of or based upon a Violation which occurs in
reliance upon and in conformity with information furnished in writing to the
Company by such Investor Indemnified Person expressly for use in the
Registration Statement or any such amendment thereof or supplement thereto; (y)
shall not apply to amounts paid in settlement of any Claim if such settlement is
effected without the prior written consent of the Company, which consent shall
not be unreasonably withheld; and (z) with respect to any preliminary
prospectus, shall not inure to the benefit of any Investor Indemnified Person if
the untrue statement or omission of material fact contained in the preliminary
prospectus was corrected on a timely basis in the prospectus, as then amended or
supplemented, if such corrected prospectus was timely made available by the
Company pursuant to Section 3(c) hereof, and the Investor Indemnified Person was
promptly advised in writing not to use the incorrect prospectus prior to the use
giving rise to a Violation and such Investor Indemnified Person, notwithstanding
such advice, used it. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of the Investor Indemnified
Person and shall survive the transfer of the Registrable Securities by the
Investors pursuant to Section 9 hereof.

      (b) In connection with any Registration Statement in which an Investor is
participating, (i) each such Investor shall, severally and not jointly,
indemnify, hold harmless and defend, to the same extent and in the same manner
set forth in Section 6(a), the Company, each

                                      -13-
<PAGE>

of its directors, each of its officers who signs the Registration Statement, its
employees and each person, if any, who controls the Company within the meaning
of Section 15 of the Securities Act or Section 20 of the Exchange Act, and any
other stockholder selling securities pursuant to the Registration Statement or
any of its directors or officers or any person who controls such stockholder
within the meaning of the Securities Act or the Exchange Act (each, a "COMPANY
INDEMNIFIED PERSON"), against any Claims to which any of them may become subject
insofar as such Claims arise out of or are based upon any Violation, in each
case to the extent (and only to the extent) that such Violation occurs in
reliance upon and in conformity with written information furnished to the
Company by such Investor expressly for use in connection with such Registration
Statement; and (ii) subject to the restrictions set forth in Section 6(c), such
Investor shall reimburse the Company Indemnified Persons, promptly as such
expenses are incurred and are due and payable, for any legal fees or other
reasonable expenses incurred by them in connection with investigating or
defending any such Claim; provided, however, that the indemnification
obligations contained in this Section 6(b) shall not apply to amounts paid in
settlement of any Claim if such settlement is effected without the prior written
consent of such Investor, which consent shall not be unreasonably withheld; and
provided, further, that the Investor shall be liable under this Agreement
(including this Section 6(b) and Section 7) for only that amount as does not
exceed the net proceeds actually received by such Investor as a result of the
sale of Registrable Securities pursuant to such Registration Statement. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of such Company Indemnified Person and shall survive the
transfer of the Registrable Securities by the Investor pursuant to Section 9
hereof. Notwithstanding anything to the contrary contained herein, the
indemnification obligations contained in this Section 6(b) with respect to any
preliminary prospectus shall not inure to the benefit of any Company Indemnified
Person if the untrue statement or omission of material fact contained in the
preliminary prospectus was corrected on a timely basis in the prospectus, as
then amended or supplemented.

      (c) Promptly after receipt by any party entitled to indemnification under
this Section 6 of notice of the commencement of any action (including any
governmental action), such indemnified party shall, if a Claim in respect
thereof is to made against any indemnifying party under this Section 6, deliver
to the indemnifying party a written notice of the commencement thereof, and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume control of the defense thereof with counsel
mutually satisfactory to the indemnifying party and the indemnified party;
provided, however, that such indemnifying party shall not be entitled to assume
such defense and an indemnified party shall have the right to retain its own
counsel with the fees and expenses to be paid by the indemnifying party, if, in
the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel of the indemnified party and the indemnifying
party would be inappropriate due to actual or potential conflicts of interest
between such indemnified party and any other party represented by such counsel
in such proceeding or the actual or potential defendants in, or targets of, any
such action include both the indemnified party and the indemnifying party and
any such indemnified party reasonably determines that there may be legal
defenses available to such indemnified party that are in conflict with those
available to such indemnifying party. The indemnifying party shall pay for only
one separate legal counsel for the indemnified parties, and such legal counsel
shall be

                                      -14-
<PAGE>

selected by Investors holding a majority in interest of the Registrable
Securities included in the Registration Statement to which the Claim relates (if
the parties entitled to indemnification hereunder are Investor Indemnified
Persons) or by the Company (if the parties entitled to indemnification hereunder
are Company Indemnified Persons). The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action shall not relieve such indemnifying party of any liability to the
indemnified party under this Section 6, except to the extent that the
indemnifying party is actually prejudiced in its ability to defend such action.
The indemnification required by this Section 6 shall be made by periodic
payments of the amount thereof during the course of the investigation or
defense, as such expense, loss, damage or liability is incurred and is due and
payable.

7.    CONTRIBUTION.

      To the extent any indemnification by an indemnifying party is prohibited
or limited by law, the indemnifying party shall make the maximum contribution
with respect to any amounts for which it would otherwise be liable under Section
6 to the fullest extent permitted by law as is appropriate to reflect the
relative fault of the indemnifying party, on the one hand, and the indemnified
party, on the other hand, with respect to the Violation giving rise to the
applicable Claim; provided, however, that (a) no contribution shall be made
under circumstances where the maker would not have been liable for
indemnification under the fault standards set forth in Section 6, (b) no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any seller of
Registrable Securities who was not guilty of such fraudulent misrepresentation,
and (c) contribution (together with any indemnification or other obligations
under this Agreement) by any seller of Registrable Securities shall be limited
in amount to the net amount of proceeds received by such seller from the sale of
such Registrable Securities.

8.    REPORTS UNDER THE EXCHANGE ACT.

      With a view to making available to the Investors the benefits of Rule 144
promulgated under the Securities Act or any other similar rule or regulation of
the SEC that may at any time permit the Investors to sell securities of the
Company to the public without registration ("RULE 144"), the Company agrees to:

      (a) file with the SEC in a timely manner and make and keep available all
reports and other documents required of the Company under the Securities Act and
the Exchange Act so long as the Company remains subject to such requirements and
the filing and availability of such reports and other documents is required for
the applicable provisions of Rule 144; and

      (b) furnish to each Investor so long as such Investor holds Preferred
Stock, Preferred Warrants, Warrants or Registrable Securities, promptly upon
request, (i) a written statement by the Company that it has complied with the
reporting requirements of Rule 144, the Securities Act and the Exchange Act,
(ii) a copy of the most recent annual or quarterly report of the Company and
such other reports and documents so filed by the Company, and (iii) such other
information

                                      -15-
<PAGE>

as may be reasonably requested to permit such Investor to sell such securities
under Rule 144 without registration.

9.    ASSIGNMENT OF REGISTRATION RIGHTS.

      The rights of the Investors hereunder, including the right to have the
Company register Registrable Securities pursuant to this Agreement, shall be
automatically assignable by each Investor to any transferee of all or any
portion of the Preferred Stock, the Preferred Warrants, the Warrants or the
Registrable Securities if: (a) the Investor agrees in writing with the
transferee or assignee to assign such rights, and a copy of such agreement is
furnished to the Company after such assignment, (b) the Company is furnished
with written notice of (i) the name and address of such transferee or assignee,
and (ii) the securities with respect to which such registration rights are being
transferred or assigned, (c) following such transfer or assignment, the further
disposition of such securities by the transferee or assignee is restricted under
the Securities Act and applicable state securities laws, (d) the transferee or
assignee agrees in writing for the benefit of the Company to be bound by all of
the provisions contained herein, and (e) such transfer shall have been made in
accordance with the applicable requirements of the Securities Purchase
Agreement, the Certificate of Designation, the Preferred Warrants and the
Warrants, as applicable. In addition, and notwithstanding anything to the
contrary contained in this Agreement, the Securities Purchase Agreement, the
Certificate of Designation, the Preferred Warrants or the Warrants, the
Securities (as defined in the Securities Purchase Agreement) may be pledged, and
all rights of the Investor under this Agreement or any other agreement or
document related to the transactions contemplated hereby may be assigned,
without further consent of the Company, to a bona fide pledgee in connection
with an Investor's margin or brokerage account.

10.   AMENDMENT OF REGISTRATION RIGHTS.

      Provisions of this Agreement may be amended and the observance thereof may
be waived (either generally or in a particular instance and either retroactively
or prospectively), only with written consent of the Company, each of the Initial
Investors (to the extent such Initial Investor or its affiliates still owns
Preferred Stock, Preferred Warrants, Warrants or Registrable Securities) and the
Investor(s) who hold a majority in interest of the Registrable Securities or, in
the case of a waiver, with the written consent of the party charged with the
enforcement of any such provision; provided, however, that (a) no amendment
hereto which restricts the ability of an Investor to elect not to participate in
an underwritten offering shall be effective against any Investor which does not
consent in writing to such amendment; (b) no consideration shall be paid to an
Investor by the Company in connection with an amendment hereto unless each
Investor similarly affected by such amendment receives a pro rata amount of
consideration from the Company; and (c) unless an Investor otherwise agrees,
each amendment hereto must similarly affect each Investor. Any amendment or
waiver effected in accordance with this Section 10 shall be binding upon each
Investor and the Company.

agreements, certificates, instruments and documents, as the other party may
reasonably request in order to carry out the intent and accomplish the purposes
of this Agreement and the consummation of the transactions contemplated hereby.

      (j) Unless other expressly provided herein, all consents, approvals and
other determinations to be made by the Investors pursuant to this Agreement
shall be made by the Investors holding a majority in interest of the Registrable
Securities (determined as if all Preferred Stock and Warrants then outstanding
had been converted into or exercised for Registrable Securities) held by all
Investors.

      (k) The initial number of Registrable Securities included on any
Registration Statement filed pursuant to Section 2(a) or 3(d), and each increase
to the number of Registrable Securities included thereon, shall be allocated pro
rata among the Investors based on the number of Registrable Securities held by
each Investor at the time of such establishment or increase, as the case may be.
In the event an Investor shall sell or otherwise transfer any of such holder's
Registrable Securities, each transferee shall be allocated a pro rata portion of
the number of Registrable Securities included on a Registration Statement for
such transferor. Any shares of Common Stock included on a Registration Statement
and which remain allocated to any person or entity which does not hold any
Registrable Securities shall be allocated to the remaining Investors, pro rata
based on the number of shares of Registrable Securities then held by such
Investors. For the avoidance of doubt, the number of Registrable Securities held
by any Investor shall be determined as if all Preferred Stock and Warrants then
outstanding, as well as all Additional Preferred Stock and Additional Warrants
issuable upon exercise of the Preferred Warrants, were converted into or
exercised for Registrable Securities.

      (l) Each party to this Agreement has participated in the negotiation and
drafting of this Agreement. As such, the language used herein shall be deemed to
be the language chosen by the parties hereto to express their mutual intent, and
no rule of strict construction will be applied against any party to this
Agreement.

      (m) For purposes of this Agreement, the term "business day" means any day
other than a Saturday or Sunday or a day on which banking institutions in the
State of New York are authorized or obligated by law, regulation or executive
order to close, and the term "trading day" means any day on which the Bulletin
Board or, if the Common Stock is not then traded on the Bulletin Board, the
principal national securities exchange, automated quotation system or other
trading market where the Common Stock is then listed, quoted or traded, is open
for trading.

RE: [NAME OF COMPANY]

Ladies and Gentlemen:

We are counsel to PDG Environmental, Inc., a corporation organized under the
laws of the State of Delaware (the "COMPANY"), and we understand that [Name of
Investor] (the "HOLDER") has purchased from the Company (i) shares of Series A
Convertible Preferred Stock that are convertible into shares of the Company's
common stock, par value $0.02 per share (the "COMMON STOCK"), (iii) warrants to
acquire shares of Common Stock and (iii) warrants to acquire (x) additional
shares of Series C Convertible Preferred Stock and (y) additional warrants to
acquire shares of Common Stock. Pursuant to a Registration Rights Agreement,
dated as of July 1, 2005, by and among the Company and the signatories thereto
(the "REGISTRATION RIGHTS AGREEMENT"), the Company agreed with the Holder, among
other things, to register the Registrable Securities (as that term is defined in
the Registration Rights Agreement) under the Securities Act of 1933, as amended
(the "SECURITIES ACT"), upon the terms provided in the Registration Rights
Agreement. In connection with the Company's obligations under the Registration
Rights Agreement, on ___________, 2005, the Company filed a Registration
Statement on Form SB-2 (File No. 333- _____________) (the "REGISTRATION
STATEMENT") with the Securities and Exchange Commission (the "SEC") relating to
the Registrable Securities, which names the Holder as a selling stockholder
thereunder. The Registration Statement was declared effective by the SEC on
_____________, 2005.

In connection with the foregoing, we advise you that a member of the SEC's staff
has advised us by telephone that the SEC has entered into an order declaring the
Registration Statement effective under the Securities Act at [time of
effectiveness] on [date of effectiveness], and we have no knowledge, after
telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC.

Based on the foregoing, we are of the opinion that the Registrable Securities
are available for resale under the Securities Act pursuant to the Registration
Statement.

Very truly yours,

[NAME OF COUNSEL]
