Warrant certificate representing such number of unexercised Warrants.

         The Company may deem and treat the registered holder(s) hereof as the
absolute owner(s) of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, and of any distribution to the holder(s) hereof, and for all
other purposes, and the Company shall not be affected by any notice to the
contrary.

         All terms used in this Warrant Certificate which are defined in the
Warrant Agreement shall have the meanings assigned to them in the Warrant
Agreement.

         IN WITNESS WHEREOF, the undersigned has executed this certificate this

                                   ARTICLE II
                    REPRESENTATIONS AND WARRANTIES OF SELLER

         Seller hereby represents and warrants, upon which representations and
warranties Purchaser relies, as follows:

         2.1. Corporate Organization. Seller is a corporation duly organized,
validly existing, and in good standing under the laws of its state of
incorporation, and has all requisite power and authority (corporate and other)
to own, lease and operate its properties and carry on its business as it is now
being conducted and to enter into this Agreement and to consummate the
transactions contemplated hereunder. Seller is qualified, licensed or registered
to do business in any states where the nature of its business and activities and
the character of the properties owned by it, require it to be so qualified,
licensed or registered, except where the failure to be so qualified, licensed or
registered would not have a materially adverse effect on the business or
operations of Seller.

         2.2. Power and Authority. Seller has the full, absolute and
unrestricted right, power, legal capacity and authority to enter into this
Agreement, and to carry out the transaction contemplated hereby; nor will it
violate any statute, law, regulation, rule, court or administrative judgment,
order, writ, injunction or decree which is applicable to Seller or any of its
properties, or to which Seller is subject or by which it is bound. All actions
of Seller necessary to authorize it to execute, deliver and consummate this
Agreement have been duly and validly authorized and taken, and no further
actions or authorizations are required. This Agreement constitutes the valid,
legally binding obligation of Seller, and is enforceable in accordance with its
terms. The Shares, when issued, will be duly authorized, validly issued, fully
paid and non-assessable. The Warrants, when issued, will be duly authorized,
validly issued and enforceable in accordance with its terms. The Securities,
when issued, will be free and clear of all liens, charges, encumbrances,
liabilities and restrictions of every kind, nature or description.

         2.3. No Violations. The execution and delivery of this Agreement and
the consummation of the transactions contemplated by this Agreement will not
result in any breach of, or constitute a default under, the Certificate or
Articles of Incorporation or Bylaws of Seller, or any agreement, instrument or
obligation to which Seller is a party or by which it or he is bound, or;

                                       2
<PAGE>

         2.4. Litigation. Seller is not a party to, or the subject of, any
action, suit, litigation, claim, administrative proceeding or governmental or
quasi-governmental investigation relating to Seller, its operations, properties,
business or prospects, or to this Agreement or the consummation or the
transactions contemplated hereby, or material to such transactions; nor to the
best of the knowledge of Seller is any such action, suit, litigation, proceeding
or investigation threatened or contemplated, nor does there exist any basis for
any of the same. Seller is not subject to any order, judgment, decree or
obligation which would limit its ability to operate its business in the ordinary
course.

         2.5. Condition of Assets. All of Seller's assets are in good operating
condition and repair, ordinary wear and tear excepted, and are adequate for the
uses to which they are being put.

         2.6. Taxes. Seller has paid (and, as to any of the following which are
payable after the date hereof, Seller has properly and adequately reserved
against and will pay when due) all income taxes, sales and use taxes,
unemployment taxes, ad valorem taxes, property taxes, excise taxes, duties and
imports, and all other taxes of every kind, character or description imposed by
any federal, state or local governmental or quasi-governmental authority
(collectively, "Taxes") required to be paid with respect to the assets or
operations of Seller for all periods prior to the Closing Date. All federal,
state and local tax returns and reports (collectively, "Returns") to be filed by
Seller with respect thereto have been accurately prepared, duly executed and
filed or will be so prepared, executed and filed before their respective due
dates, and all Taxes due with respect to such returns as filed have been paid
(or will be so paid) by Seller in full. Seller has not received, and there are
not outstanding, any notices of any deficiencies, adjustments, assessments or
changes in assessments or increases in Taxes or tax rates with respect to any
Taxes, or other charges which are due or required to be filed at or prior to the
date hereof, and which have not been paid in full or otherwise fully settled and
satisfied. No extension of time is in effect for the assessment of deficiencies
against Seller nor has any waiver of any statute of limitations with respect to
any taxable year.

         2.7. Compliance with Laws. Seller has complied with, and is currently
in compliance with all statutes, laws, ordinances, rules, regulations,
judgments, decrees and orders, of any government, court or governmental or
quasi-governmental authority, to which it is subject or by which it is bound.
Seller has all permits, licenses and authorizations required for the operation
of its business as it is presently conducted ("Permits"), and all of such
Permits are in full force and effect.

                                       3
<PAGE>

         2.8. Insurance. Seller maintains adequate policies of fire, liability,
title, professional liability, theft, employee fidelity workers' compensation
and all other forms of casualty and liability insurance. All of such policies
are sufficient for compliance with all requirements of law and of all contracts,
commitments and agreements of any nature to which Seller is a party, and provide
coverage for property in limits of not less than the amounts sufficient to
replace all property owned by Seller upon loss, with no co-insurance penalties
applicable thereto. Seller is not in default under any of such policies or
binders, and Seller has not failed to give any notice or to present any claim
under any such policy or binder in a due and timely fashion. There are no facts
upon which an insurer might be justified in reducing coverage or increasing
premiums on existing policies or binders. There are no outstanding unpaid claims
under any such policies or binders.

         2.9. Public Reports. Seller has heretofore delivered to Purchaser
copies of all reports filed with the Securities and Exchange Commission during
the 12 months preceding the date hereof. The financial statements contained in
such reports are referred to herein as the "Financial Statements."

         The Financial Statements are in accordance with Seller's books and
records and fairly present Seller's financial position, results of operations
and cash flows as of the dates and for the periods indicated. As of the date of
the Financial Statements, Seller did not have any material liabilities or
obligations of any kind, whether direct or indirect, accrued, absolute,
contingent or otherwise, required to be disclosed and which are not so disclosed
in the Financial Statements. With respect to Seller's contracts, agreements and
commitments, the Financial Statements contain and reflect reserves for all
liabilities and for all reasonably anticipated losses and costs, if any, in
excess of expected receipts.

         2.10. Accuracy of Representations and Warranties. None of the
representations and warranties made by Seller contained in this Agreement,
including all Exhibits, nor in any statement, document, certificate, schedule,
list, memorandum or other writing (collectively, "Statements") furnished or to
be furnished by Seller pursuant hereto, or in connection with the transactions
contemplated hereby, is or will be incorrect or incomplete, or contains or will
contain any untrue statement of fact, and none of such representations,
warranties and Statements omits or will omit to state a fact necessary in order
to make the statements contained herein or therein not misleading. There is no
fact known to Seller which Seller has not disclosed in this Agreement, or in an
Exhibit hereto, or in a Statement, which adversely affects or may reasonably be
expected to affect adversely the business or assets of Seller.

                   REPRESENTATIONS AND WARRANTIES OF PURCHASER

         Purchaser represents and warrants to Seller, upon which representations
and warranties Seller relies, as follows:

         3.1. Power and Authority. Purchaser has, and will at Closing have, the
full, absolute and unrestricted right, power, legal capacity and authority to
enter into this Agreement and to carry out the transaction contemplated hereby;
nor will it violate any statute, law, regulation, rule, court or administrative
judgment, order or decree which is applicable to Purchaser, or to which it is
subject or by which it is bound. This Agreement constitutes the valid, legally
binding obligation of Purchaser and is enforceable in accordance with its terms.

         3.2. Litigation. Purchaser is not a party to, or the subject of, any
action, suit, litigation, claim, administrative proceeding or governmental or
quasi-governmental investigation relating this Agreement or the consummation or
the transactions contemplated hereby, or material to such transactions; nor to
the best of the knowledge of Purchaser is any such action, suit, litigation,
proceeding or investigation threatened or contemplated, nor does there exist any
basis for any of the same.

         3.3. Acquisition for Investment. Purchaser has such knowledge and
experience in financial and business matters that they are capable of evaluating
the merits and risks of the investment in the Securities, and each is able to
bear the economic risks of such investment. Purchaser acknowledges that:

              (i) they have been given the opportunity to ask questions of
Seller's management; and

              (ii) the sale of the Securities has not been registered under the
Securities Act of 1933, as amended (the "Securities Act"); there is no
commitment to register the Securities under the Securities Act except as
provided in Article IV; and the Purchaser is relying on the exemption from such
registration provided by Section 4(2) of the Securities Act as a transaction by
an issuer not involving a public offering. Purchaser acknowledge that the
certificates for the Securities comprising which the undersigned will receive
will contain a legend substantially as follows:

         THE SECURITIES WHICH ARE REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT").
         THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT PURPOSES ONLY AND NOT
         WITH A VIEW TO DISTRIBUTION OR RESALE, AND MAY NOT BE SOLD,
         TRANSFERRED, MADE SUBJECT TO A SECURITY INTEREST, PLEDGED, HYPOTHECATED
         OR OTHERWISE DISPOSED OF UNLESS AND UNTIL REGISTERED UNDER THE ACT, OR
         EVIDENCE SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT
         REQUIRED UNDER SUCH ACT.

                                       5
<PAGE>

         The undersigned further acknowledges that a stop transfer order will be
placed upon the certificates for the securities in accordance with the Act. The
undersigned further acknowledges that the Company is under no obligation to aid
the undersigned in obtaining any exemption from registration requirements.

         3.4. Accuracy of Representations and Warranties. None of the
representations and warranties made by Purchaser contained in this Agreement,
including all Exhibits, nor in any Statement furnished or to be furnished by
Purchaser pursuant hereto, or in connection with the transactions contemplated
hereby, is or will be incorrect or incomplete, or contains or will contain any
untrue statement of fact, and none of such representations, warranties and
Statements omits or will omit to state a fact necessary in order to make the
statements contained herein or therein not misleading.

                                   ARTICLE IV
                               REGISTRATION RIGHTS

         4.1 Registration. Seller shall prepare and file with the Commission a
Registration Statement (the "Initial Registration Statement") which shall cover
the Securities, including the shares of Common Stock issuable upon exercise of
the Warrants (collectively, the "Registrable Securities") for an offering to be
made on a continuous basis pursuant to a "Shelf" registration statement under
Rule 415. The Initial Registration Statement shall be on Form S-3 or any
successor form (except if Seller is not then eligible to register for resale the
Registrable Securities on Form S-3, in which case such registration shall be on
another appropriate form in accordance herewith). Seller shall use its best
efforts to cause the Initial Registration Statement to be declared effective
under the Securities Act as promptly as possible after the filing thereof, and
to keep such Initial Registration Statement continuously effective under the
Securities Act until the date which is three years after the date that such
Initial Registration Statement is declared effective by the Securities and
Exchange Commission ("Commission") or such earlier date when all Registrable
Securities covered by such Initial Registration Statement have been sold or may
be sold without volume restrictions pursuant to Rule 144 as determined by
counsel to Seller pursuant to a written opinion letter, addressed to Seller's
transfer agent to such effect (the "Effectiveness Period").

                                       6
<PAGE>

         "Effectiveness Date" means the earlier of (i) the 90th day following
the Closing Date, or (ii) the fifth day after the Company has received written
notice from the Commission that the Commission Staff will not be reviewing the
Registration Statement or has no further comments on the Registration Statement,
unless the Purchaser consents in writing to a longer period, such consent not to
be unreasonably withheld.

         If the Initial Registration Statement covering all the applicable
Registrable Securities and required to be filed by Seller pursuant to this
Agreement is not declared effective by the Commission on or before the
Effectiveness Date, then, as relief for the damages to the Purchaser 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 equitable
remedies), Seller shall issue and deliver to Purchaser an additional Warrant
(containing the same terms and conditions as the Warrants being delivered on the
date hereof) to purchase an aggregate of 2,500 shares of Common Stock for each
month during which the Initial Registration Statement is not declared effective.
Such amount shall be prorated for any additional portion of a month.

         4.2 Expenses. All expenses incurred in the registration of the
Registrable Securities shall be paid by Seller, including, without limitation,
printing expenses, fees and disbursements of counsel for Seller, all
registration and filing fees for the Purchaser's Securities under federal and
state securities laws, and expenses of complying with the securities or blue sky
laws of any jurisdictions; provided, however, Seller shall not be liable for (a)
any discounts or commissions to any underwriter; (b) any stock transfer taxes
incurred with respect to Securities sold, or (c) the fees and expenses of
counsel for Purchaser, provided that Seller will pay the costs and expenses of
Seller's counsel when Seller's counsel is representing any or all selling
security holders.

         4.3. Indemnification. In the event the Registrable Securities are
included in a registration statement pursuant to this Agreement:

                                       7

         i. Seller Indemnity. Seller shall indemnify and hold harmless the
Purchaser, the affiliates, officers, directors and partners of Purchaser, any
underwriter (as defined in the Act) for Purchaser, and each person, if any, who
controls such Purchaser or underwriter (within the meaning of the Act or the
Securities Exchange Act of 1934 (the "Exchange Act"), against any losses,
claims, damages or liabilities (joint or several) to which they may become
subject under the Act, the Exchange Act or other federal or state law, insofar
as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon any of the following statements, omissions or
violations (collectively a "Violation"): (i) any untrue statement or alleged
untrue statement of a material fact contained in such registration statement
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein, (iii) any violation or alleged violation by Seller
of the Act, the Exchange Act, or (iv) any state securities law or any rule or
regulation promulgated under the Act, the Exchange Act or any state securities
law; provided, however, that Seller shall not be liable to Purchaser in any such
case for any such loss, claim, damage, liability or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by Purchaser or any other officer, director or
controlling person thereof.

         ii. Purchaser Indemnity. Purchaser shall indemnify and hold harmless
Seller, its affiliates, its counsel, officers, directors, shareholders and
representatives, any underwriter (as defined in the Act) and each person, if
any, who controls Seller or the underwriter (within the meaning of the Act or
liabilities (joint or several) to which they may become subject under the Act,
the Exchange Act or any state securities law, and Seller shall reimburse Seller
and each such affiliate, officer or director or partner, underwriter or
controlling person for any legal or other expenses incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action; insofar as such losses, claims, damages or liabilities (or
actions and respect thereof) arise out of or are based upon any statements or
information provided by Purchaser to Seller in connection with the offer or sale
of Registrable Securities.

any stock option plan, (iii) enter into any contracts, commitments or agreements
of any kind to effectuate any of the forging transactions with any person,
entity or other association other than Purchaser for a transaction with a value
in excess of $4 million (collectively, a "Third-Party Financing Transaction"),
Seller shall give the Purchaser (within five (5) business days of the completion
of such Third-Party Financing Transaction) written notice (a "Financing Notice")
of such Third-Party Financing Transaction stating with reasonable specificity
the general terms and conditions of the Third-Party Financing Transaction.
Seller hereby grants the Purchaser the irrevocable right for a period of five
business days from Purchasers' receipt of the Financing Notice in which to elect
to participate in an additional financing transaction (a "Purchaser
Participating Financing") with the Company on the same terms and conditions (but
only to the extent of 25% of value of the Third-Party Financing Transaction) as
the completed Third-Party Financing Transaction. The Purchaser shall elect to
participate in the Purchaser Participating Financing by delivering written
notice of its election to Seller before the end of the five (5) Business Day
period after receipt of the Financing Notice. Thereafter, Seller and the
Purchasers shall close the Purchaser Participating Financing as promptly as
possible and in any event within 90 days of the closing of the Third-Party
Financing Transaction. The Purchaser shall participate in the Purchaser
Participating Financing in the same proportion as their participation in the
financing on the date hereof.
