         As used in this Warrant, the following terms have the respective
meanings set forth below:

         "Affiliate" of any Person means any other Person which directly, or
indirectly through one or more intermediaries, controls, or is controlled by, or
is under common control with, such Person. The term "control" (including the
terms "controlling," "controlled by" and "under common control with") as used
with respect to any Person means the possession, direct or indirect, of the
power to direct or cause the direction of the management and policies of such
Person, whether through the ownership of voting securities, by contract or
otherwise. Notwithstanding anything to the contrary herein, none of (i) the
Holder (and its Affiliates) nor (ii) any of the individual Founders (and their
Affiliates) shall be deemed to be an Affiliate of any other.

         "Appraisal Procedure" means the following procedure to determine the
fair market value, as to any security, for purposes of the definition of "Fair
Market Value" or the fair market value, as to any other property (in either
case, the "Valuation Amount"). The Valuation Amount shall be determined in good
faith jointly by the Board of Directors and NYMEX, as representative of the
Holders; provided, however, that if such parties are not able to agree on the
Valuation Amount within a reasonable period of time (not to exceed twenty (20)
Business Days), the Valuation Amount shall be determined by an investment
banking firm of national reputation, which firm shall be reasonably acceptable
to the Board of Directors and NYMEX. If the Board of Directors and NYMEX are
unable to agree upon an acceptable investment banking firm within ten (10) days
after the date either party proposed that one be selected, the investment
banking firm will be selected by an arbitrator located in New York City, New
York, selected by the American Arbitration Association (or if such organization
ceases to exist, the arbitrator shall be chosen by a court of competent
jurisdiction). The arbitrator shall select the investment banking firm (within
ten (10) days of his appointment) from a list, jointly prepared by the Board of
Directors and NYMEX, of not more than six investment banking firms of national
reputation in the United States, of which no more than three may be named by the
Board of Directors and no more than three may be named by NYMEX. The arbitrator
may consider, within the ten day period allotted, arguments from the parties
regarding which investment banking firm to choose, but the selection by the
arbitrator shall be made in its sole discretion from the list of six. The Board
of Directors and NYMEX shall submit their respective valuations and other
relevant data to the investment banking firm, and the investment banking firm
shall, within thirty days of its appointment, make its own determination of the
Valuation Amount. The determination of the final Valuation Amount by such
investment banking firm shall be final and binding upon the parties. The Company
and NYMEX shall each bear 50% of the fees and expenses of the investment banking
firm and arbitrator (if any) used to determine the Valuation Amount. If required
by any such investment banking firm or arbitrator, the Company shall execute a
retainer and engagement letter containing reasonable terms and conditions,
including, without limitation, customary provisions concerning the rights of
indemnification and contribution by the Company in favor of such investment
banking firm or arbitrator and its officers, directors, partners, employees,
agents and Affiliates.

         Company to any underwriter or placement agent in connection with the
         issuance and sale thereof.

                           (ii) In the case of the issuance of capital stock for
         a consideration in whole or in part other than cash, the consideration
         other than cash shall be deemed to be the Fair Market Value thereof.

                           (iii) In the case of the issuance of options to
         purchase or rights to subscribe for capital stock, securities by their
         terms convertible into or exchangeable for capital stock, or options to
         purchase or rights to subscribe for such convertible or exchangeable
         securities (except for options to acquire Excluded Stock (as defined in
         Section 4.11 hereof)):

          (A)  the aggregate maximum number of shares of capital stock
               deliverable upon exercise of any such options to purchase or
               rights to subscribe for capital stock shall be deemed to have
               been issued at the time such options or rights were issued and
               for a consideration equal to the consideration (determined in the
               manner provided in subparagraphs (i) and (ii) of this Section
               4.2), if any, received by the Company upon the issuance of such
               options or rights plus the minimum purchase price provided in
               such options or rights for the capital stock covered thereby;

          (B)  the aggregate maximum number of shares of capital stock
               deliverable upon conversion of or in exchange for any such
               convertible or exchangeable securities or upon the exercise of
               options to purchase or rights to subscribe for such convertible
               or exchangeable securities and subsequent conversion or exchange
               thereof shall be deemed to have been issued at the time such
               securities, options, or rights were issued and for a
               consideration equal to the consideration received by the Company
               for any such securities and related options or rights (excluding
               any cash received on account of accrued interest or accrued
               dividends), plus the additional consideration, if any, to be
               received by the Company upon the conversion or exchange of such
               securities or the exercise of any related options or rights (the
               consideration in each case to be determined in the manner
               provided in paragraphs (i) and (ii) of this Section 4.2);

                                       10
<PAGE>

          (C)  on any change in the number of shares or exercise price of
               capital stock deliverable upon exercise of any such options or
               rights or conversions of or exchanges for such securities, other
               than a change resulting from the anti dilution provisions
               thereof, the Exercise Price shall forthwith be readjusted to such
               Exercise Price as would have been obtained had the adjustment
               made upon the issuance of such options, rights or securities not
               converted prior to such change or options or rights related to
               such securities not converted prior to such change been made upon
               the basis of such change;

          (D)  upon the expiration of any options to purchase or rights to
               subscribe for capital stock which shall not have been exercised,
               the Exercise Price computed upon the original issue thereof (or
               upon the occurrence of a record date with respect thereto), and
               any subsequent adjustments based thereon, shall, upon such
               expiration, be recomputed as if the only additional shares of
               capital stock issued were the shares of capital stock, if any,
               actually issued upon the exercise of such options to purchase or
               rights to subscribe for capital stock, and the consideration
               received therefor was the consideration actually received by the
               Company for the issue of the options to purchase or rights to
               subscribe for capital stock that were exercised, plus the
               consideration actually received by the Company upon such
               exercise; and

          (E)  no further adjustment of the
               Exercise Price adjusted upon the
               issuance of any such options,
               rights, convertible securities or
               exchangeable securities shall be
               made as a result of the actual
               issuance of capital stock on the
               exercise of any such rights or
               options or any conversion or
               exchange of any such securities.

                  4.3      Upon Stock Dividends, Subdivisions or Splits.

                  (a) If, at any time after the Original Issue Date and on or
before the Expiration Date, the number of shares of Common Stock Outstanding is
increased by a stock dividend payable in shares of Common Stock or by a
subdivision or split up of shares of Common Stock, then, following the record
date for the determination of holders of Common Stock entitled to receive such
stock dividend, or to be affected by such subdivision or split up, the Exercise
Price shall be appropriately decreased by multiplying the Exercise Price by a
fraction, the numerator of which is the number of shares of Common Stock
Outstanding immediately prior to such increase and the denominator of which is
the number of shares of Common Stock Outstanding immediately after such increase
in Outstanding shares.

                                       11
<PAGE>

                  (b) If, at any time after the Original Issue Date, the Company
shall declare or pay a dividend or make a distribution to all or substantially
all holders of Outstanding Common Stock, in either case, of evidences of
indebtedness, cash or other property or securities (excluding dividends referred
to in Section 4.3(a) above) or shall issue to all or substantially all holders
of Outstanding Common Stock rights or warrants to subscribe for or purchase any
of its securities (other than options to purchase or rights to subscribe for
Common Stock, securities by their terms convertible into or exchangeable for
Common Stock, or options to purchase or rights to subscribe for such convertible
or exchangeable securities in respect of which the Holder becomes entitled to
purchase Common Stock or securities by their terms convertible into or
exchangeable for Common Stock referred to in Section 4.1 above), then in each
such case the Exercise Price shall be forthwith lowered so that the same shall
equal the price determined by multiplying the Exercise Price in effect
immediately prior to the close of business on the date (the "Record Date") fixed
for the determination of holders of Common Stock entitled to receive such
dividend or distribution by a fraction, (i) the numerator of which shall be the
Fair Market Value of the Common Stock as of the Business Day next preceding the
Record Date less the Fair Market Value, as of the Record Date, of the portion of
the evidences of indebtedness, cash or other property or securities so
distributed, or of such rights or warrants, in each case, applicable to one
share of Common Stock, and (ii) the denominator of which shall be the Fair
Market Value of the Common Stock as of the Business Day next preceding the
Record Date, with such adjustment to become effective immediately prior to the
opening of business on the day following the Record Date. Notwithstanding the
foregoing, in the event that, with respect to any dividend or distribution to
which this Section 4.3(b) would otherwise apply, the numerator in the fraction
referred to in the first sentence of this Section 4.3(b) is zero (or is a
negative number), then the adjustment provided by this Section 4.3(b) shall not
be made and in lieu of such adjustment, the Company shall deliver to the Holder
on the date fixed for payment to stockholders of the Company of such divided or
distribution, the evidences of indebtedness, assets, other property or
securities, rights or warrants so distributed in respect of the number of shares
of Warrant Stock (determined as of the close of business on the Record Date)
issuable upon exercise hereof.

                  4.4 Upon Combinations or Reverse Stock Splits. If, at any time
after the Original Issue Date, the number of shares of Common Stock Outstanding
is decreased by a combination or reverse stock split of the Outstanding shares
of Common Stock into a smaller number of shares of Common Stock, then, following
the record date to determine shares affected by such combination or reverse
stock split, the Exercise Price shall be appropriately increased by multiplying
the Exercise Price by a fraction, the numerator of which is the number of shares
of Common Stock Outstanding immediately prior to such decrease and the
denominator of which is the number of shares of Common Stock Outstanding
immediately after such decrease in Outstanding shares.

                                       12
<PAGE>

                  4.5 Upon Reclassifications, Reorganizations, Consolidations or
Mergers. In the event of any capital reorganization of the Company, any
reclassification of the stock of the Company (other than a change in par value
or from par value to no par value or from no par value to par value or as a
result of a stock dividend or subdivision, split up or combination of shares),
or any consolidation or merger of the Company with or into another Person (where
the Company is not the surviving Person or where there is a change in or
distribution with respect to the Common Stock), each Warrant shall after such
reorganization, reclassification, consolidation, or merger be exercisable for
the kind and number of shares of stock or other securities or property of the
Company or of the successor Person resulting from such consolidation or
surviving such merger, if any, to which the holder of the number of shares of
Common Stock deliverable (immediately prior to the time of such reorganization,
reclassification, consolidation or merger) upon exercise of such Warrant would
have been entitled upon such reorganization, reclassification, consolidation or
merger. The provisions of this clause shall similarly apply to successive
reorganizations, reclassifications, consolidations, or mergers. The Company
shall not effect any such reorganization, reclassification, consolidation or
merger unless, prior to the consummation thereof, the successor Person (if other
than the Company) resulting from such reorganization, reclassification,
consolidation or merger, shall assume, by written instrument, the obligation to
deliver to the Holders such shares of stock, securities or assets, which, in
accordance with the foregoing provisions, such Holders shall be entitled to
receive upon such conversion.

                  4.6 Deferral in Certain Circumstances. In any case in which
the provisions of this Section 4 shall require that an adjustment shall become
effective immediately after a record date of an event, the Company may defer
until the occurrence of such event (a) issuing to the Holder with respect to any
Warrants exercised after such record date and before the occurrence of such
event the shares of capital stock issuable upon such exercise by reason of the
adjustment required by such event and issuing to such Holder only the shares of
capital stock issuable upon such exercise before giving effect to such
adjustments, and (b) paying to such Holder any amount in cash in lieu of a
fractional share of capital stock pursuant to Section 2.3 above; provided,
however, that the Company shall deliver to such Holder an appropriate instrument
or due bills evidencing such Holder's right to receive such additional shares or
such cash.

                  4.7 Appraisal Procedure. In any case in which the provisions
of this Section 4 shall necessitate that the Appraisal Procedure be utilized for
purposes of determining an adjustment to the Exercise Price, the Company may
defer until the completion of the Appraisal Procedure and the determination of
the adjustment (1) issuing to the Holder of any Warrant exercised after the date
of the event that requires the adjustment and before completion of the Appraisal
Procedure and the determination of the adjustment, the shares of capital stock
issuable upon such exercise by reason of the adjustment required by such event
and issuing to such Holder only the shares of capital stock issuable upon such
exercise before giving effect to such adjustment and (2) paying to such Holder
any amount in cash in lieu of a fractional share of capital stock pursuant to
Section 2.3 above; provided, however, that the Company shall deliver to such
Holder an appropriate instrument or due bills evidencing such Holder's right to
receive such additional shares or such cash.

                  4.8 Adjustment of Number of Shares Purchasable. Upon any
adjustment of the Exercise Price as provided in Sections 4.1, 4.3, 4.4 and 4.5
Holders of the Warrants shall thereafter be entitled to purchase upon the
exercise thereof, at the Exercise Price resulting from such adjustment, the
number of shares of Warrant Stock (calculated to the nearest 1/100th of a share)
obtained by multiplying the Exercise Price in effect immediately prior to such
adjustment by the number of shares of Warrant Stock issuable on the exercise
hereof immediately prior to such adjustment and dividing the product thereof by
the Exercise Price resulting from such adjustment.

                  4.9      Notice of Adjustment of Exercise Price.  Whenever the
Exercise Price is adjusted as herein provided:

                           (i) the Company shall compute the adjusted Exercise
         Price in accordance with this Section 4 and shall prepare a certificate
         signed by the treasurer or chief financial officer of the Company
         setting forth the adjusted Exercise Price and showing in reasonable
         detail the facts upon which such adjustment is based, and such
         certificate shall forthwith be filed at the Designated Office; and

                           (ii) a notice stating that the Exercise Price has
         been adjusted and setting forth the adjusted Exercise Price shall
         forthwith be prepared by the Company, and as soon as practicable after
         it is prepared, such notice shall be mailed by the Company at its
         expense to all Holders at its last address as it shall appear in the
         warrant register.

                  4.10 Form of Warrant. Irrespective of and without limiting any
adjustment in the Exercise Price or the number of shares purchasable upon the
exercise of the Warrant, Warrants thereafter issued may continue to express the
same price and number and kind of shares as are stated in the original Warrant.

                  4.11 Exceptions. This Section 4 shall not apply to any shares
of Common Stock (A) issued upon exercise of options granted under the Company's
2004 stock option plan, (B) issued upon exercise of any other options, warrants
or other rights outstanding on the date hereof, (C) issued to officers and
employees pursuant to employment agreements in existence on the date hereof, (D)
issued as consideration when any corporation or business is acquired, merged
into, or becomes part of the Company or a subsidiary of the Company, (E) issued
upon exercise of any options, warrants or other rights assumed by the Company in
connection with a merger or other acquisition, provided, that such options,
warrants or other rights assumed by the Company shall not have been issued in
connection with or in contemplation of such merger or acquisition, (F) issued in
good faith in connection with any other acquisition of assets in an arms-length
transaction between the Company and an unaffiliated third party, (G) issued to,
or pursuant to rights granted to, unaffiliated market makers who enter into
warrant agreements with the Company and the issuance of such shares, or the
exercise of such rights, is (x) subject to the achievement by the market maker
of specified volume milestones in cleared products, and (y) at an issuance, or
exercise, price that is not less than the fair market value of the Common Stock
on the date of grant, or (H) issued to, or pursuant to rights granted to,
unaffiliated landlords, equipment lessors, lenders, other financial
institutions, or other vendors to, or strategic partners of, the Company
(collectively, the "Excluded Stock"); provided, that any shares issuable
pursuant to sections (D), (F) and (H) above in excess of 300,000 shares in the
aggregate, and any shares issuable pursuant to section (G) above in excess of
1,200,000 shares in the aggregate shall not constitute Excluded Stock.

5.       NO IMPAIRMENT; REGULATORY COMPLIANCE AND COOPERATION

         The Company shall not by any action, including, without limitation,
amending its charter documents or through any reorganization, reclassification,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other similar 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 the Holder against impairment. Without limiting the generality of the
foregoing, the Company shall take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of Warrant Stock upon the exercise of this Warrant,
free and clear of all Liens, and shall use its commercially reasonable efforts
to obtain 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.

6.       RESERVATION AND AUTHORIZATION OF COMMON STOCK

                  6.1 The Company shall at all times reserve and keep available
for issuance upon the exercise of the Warrant such number of its authorized but
unissued shares of Common Stock as will be required for issuance of the Warrant
Stock. All shares of Warrant Stock issuable pursuant to the terms of this
Warrant, when issued upon exercise of this Warrant with payment therefor in
accordance with the terms hereof, shall be duly and validly issued and fully
paid and nonassessable, not subject to preemptive rights and shall be free and
clear of all Liens. Before taking any action that would result in an adjustment
in the number of shares of Warrant Stock 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 over such action. If any shares of
Warrant Stock required to be reserved for issuance upon exercise of the Warrant
require registration or qualification with any Governmental Entity under any
federal or state law (other than under the Securities Act or any state
securities law) before such shares may be so issued, the Company will in good
faith and as expeditiously as possible and at its expense endeavor to cause such
shares to be duly registered.

                  6.2 Before taking any action that would cause an adjustment
reducing the Exercise Price below the then par value (if any) of the shares of
Warrant Stock deliverable upon exercise of the Warrant or that would cause the
number of shares of Warrant Stock issuable upon exercise of the Warrant to
exceed (when taken together with all other Outstanding shares of Common Stock)
the number of shares of Common Stock that the Company is authorized to issue,
the Company will take any corporate action that, in the opinion of its counsel,
is necessary in order that the Company may validly and legally issue the full
number of fully paid and nonassessable shares of Warrant Stock issuable upon
exercise of the Warrant at such adjusted exercise price.

7.       NOTICE OF CORPORATE ACTIONS; TAKING OF RECORD; TRANSFER BOOKS;
WARRANTHOLDER NOT DEEMED A STOCKHOLDER

Expiration Date there shall be:

Stock, rights or warrants to subscribe for or purchase any shares of capital

subdivision or combination of the outstanding shares of Common Stock), or of any
consolidation, merger or share exchange to which the Company is a party and for
which approval of any stockholders of the Company is required, or of the sale or
transfer of all or substantially all of the assets of the Company (except (i) a
merger or other reorganization in which the Company shall be the surviving
corporation and holders of Common Stock receive no consideration in respect of
their shares and (ii) a merger of the Company into a wholly owned subsidiary of
the Company, the principal purpose of which, in the good faith determination of
the Board of Directors, is to change the state of incorporation of the Company);
or

                  (c)      of the voluntary or involuntary dissolution,
liquidation or winding up of the Company;

                  (d) the Company or any Subsidiary shall commence a tender
offer for all or a portion of the Outstanding shares of Common Stock (or shall
amend any such tender offer to change the maximum number of shares being sought
or the amount or type of consideration being offered therefore);

then the Company shall cause to be filed at the Designated Office, and shall
cause to be mailed to NYMEX at its last address as it shall appear in the
warrant register, (i) at least twenty (20) days prior to the applicable record
or effective date hereinafter specified, a notice stating (x) the date on which
a record is to be taken for the purpose of such dividend, distribution or
granting of rights or warrants, or, if a record is not to be taken, the date as
of which the holders of Common Stock of record who will be entitled to such
dividend, distribution, rights or warrants are to be determined, or (y) the date
on which such reclassification, consolidation, merger, share exchange, sale,
transfer, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of Common Stock
of record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, share exchange, sale, transfer, dissolution, liquidation
or winding up, or (ii) on the date on which such tender offer commenced, a
notice stating the date on which such tender offer commenced, the date on which
such tender offer is scheduled to expire unless extended, the consideration
offered and the other material terms thereof (or the material terms of the
amendment thereto. Such notice shall also set forth such facts with respect
thereto as shall be reasonably necessary to indicate the effect of such action
(to the extent such effect may be known at the date of such notice) on the
Exercise Price and the number and kind or class of shares or other securities or
property which shall be deliverable or purchasable upon the occurrence of such
action or deliverable upon exercise of the Warrant. Neither the failure to give
any such notice nor any defect therein shall affect the legality or validity of
any action described in clauses (a) through (d) of this Section 7.1.

                  7.2 Taking of Record. In the case of all dividends or other
distributions by the Company to the holders of its Common Stock with respect to
which any provision hereof refers to the taking of a record of such holders, the
Company will in each such case take such a record and will take such record as
of the close of business on a Business Day.

                  7.3 Closing of Transfer Books. The Company shall not at any
time close its stock transfer books so as to result in preventing or delaying
the exercise of the Warrant.

                  7.4 Warrant Holder Not Deemed a Stockholder. The Company may
deem and treat the registered Holder of the Warrant as the absolute owner
thereof (notwithstanding any notation of ownership or other writing thereon made
by anyone), for the purpose of any exercise thereof and for all other purposes,
and neither the Company nor any agent thereof shall be affected by any notice to
the contrary. Accordingly, the Company shall not be bound to recognize any
equitable or other claim to, or interest in, the Warrant on the part of any
Person other than such registered Holder, whether or not it shall have express
or other notice thereof. Prior to the valid exercise of the Warrant, no Holder
of the Warrant, as such, shall be entitled to any rights of a stockholder of the
Company, including, without limitation, the right to vote or to consent to an
action of the stockholders, to receive dividends or other distributions, to
exercise any preemptive right, or to receive any notice of meetings of
stockholders and, except as otherwise provided in the Agreement, shall not be
entitled to receive any notice of any proceedings of the Company.

8.       OFFICE OF THE COMPANY

         As long as the Warrant remains outstanding, the Company shall maintain
an office or agency, which may be the principal executive offices of the Company
(the "Designated Office"), where the Warrant may be presented for exercise,
registration of transfer, division or combination as provided in this Warrant.
Such Designated Office shall initially be the office of the Company at 465
Columbus Avenue, Valhalla, New York 10595. The Company may from time to time
change the Designated Office to another office of the Company or its agent
within the United States by notice given to all registered Holders at least ten
(10) Business Days prior to the effective date of such change.

9.       MISCELLANEOUS

                  9.1 No Implied Waivers. No failure or delay by any party in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The rights and remedies herein provided shall be cumulative and not exclusive of
any rights or remedies provided by law.

                  9.2 Notices. All notices, requests, consents and other
communications required or permitted hereunder shall be in writing and shall be
hand delivered or mailed postage prepaid by registered or certified mail or

                  9.3 Limitation of Liability. No provision hereof, in the
absence of affirmative action by the Holder to purchase shares of Warrant Stock,
and no enumeration herein of the rights or privileges of the Holder hereof,
shall give rise to any liability of such Holder to pay the Exercise Price for
any Warrant Stock other than pursuant to an exercise of this Warrant or any
liability as a stockholder of the Company, whether such liability is asserted by
the Company or by creditors of the Company.

                  9.4 Remedies. Each Holder of Warrants and/or Warrant Stock, in
addition to being entitled to exercise its rights granted by law, including
recovery of damages, shall be entitled to specific performance of its rights
provided 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, in an action for specific
performance, to waive the defense that a remedy at law would be adequate.

                  9.5 Successors and Assigns. This Warrant and the rights and
obligations evidenced hereby shall inure to the benefit of and be binding upon
the successors of the Company and the permitted successors and assigns of the
Holder hereof.

                  9.6 Amendment. This Warrant and all other Warrants may be
modified or amended or the provisions hereof waived only with the written
consent of the Company and the Holder or, in the case of any transfer of this
Warrant to multiple Persons, the written consent of the Company and two-thirds
of the Holders. Notwithstanding the foregoing, without a Holder's written
consent no such modification, amendment or waiver shall affect adversely such
Holder's rights hereunder in a discriminatory manner inconsistent with its
adverse effects on rights of other Holders hereunder (other than as reflected by
the different number of shares of Warrant Stock held by such Holders). This
Warrant cannot be changed, modified, discharged or terminated by oral agreement.

                  9.7 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
provision or the remaining provisions of this Warrant.

                  9.8 Headings. The headings and other captions in this Warrant
are for the convenience and reference only and shall not be used in
interpreting, construing or enforcing any provision of this Warrant.

                  9.9 Governing Law; Jurisdiction; Waiver of Jury Trial. The
Internal Laws, and not the laws of conflicts (other than Section 5 1401 of the
general obligations law of the state of New York), of New York shall govern the
enforceability and validity of this warrant, the construction of its terms and
the interpretation of the rights and duties of the Company. Any suit, action or
proceeding seeking to enforce any provision of, or based on any matter arising
out of or in connection with, this Warrant or any other Warrant or the
transactions contemplated hereby may be brought in any federal or state court
located in the County and State of New York, and each of the parties hereby
consents to the jurisdiction of such courts (and of the appropriate appellate
courts therefrom) in any such suit, action or proceeding and irrevocably waives,
to the fullest extent permitted by law, any objection which it may now or
hereafter have to the laying of the venue of any such suit, action or proceeding
in any such court or that any such suit, action or proceeding which is brought
in any such court has been brought in an inconvenient forum. Process in any such
suit, action or proceeding may be served on any party anywhere in the world,
whether within or without the jurisdiction of any such court. Without limiting
the foregoing, each party agrees that service of process on such party as
provided in Section 9.2 shall be deemed effective service of process on such
party.

                  9.10 Aggregation of Stock. All Warrant Stock held by or
acquired by Affiliated Persons will be aggregated together for the purpose of
determining the availability of any rights under this Warrant.

                  9.11 Entire Agreement. This Warrant contains the entire
agreement with respect to the subject matter hereof and supersedes and replaces
all other prior agreements, written or oral, with respect to the subject matter
hereof.

                  9.12     Waiver of Jury Trial.  EACH OF THE PARTIES HERETO
HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY

                                    (i) The License Agreements are valid and
          binding obligations of the Company, enforceable against the Company in
          accordance with their respective terms (except to the extent
          enforcement may be limited by (a) bankruptcy, insolvency,
          reorganization, moratorium or similar laws now or hereafter in effect
          relating to creditors' rights generally, and (b) general principles of
          equity (regardless of whether enforceability is considered in a
          proceeding at law or in equity), and there exists no event or
          condition which will result in a violation or breach of, or constitute
          (with or without due notice or lapse of time or both) a default by the
          Company or any Subsidiary or to the Knowledge of the Company, of any
          other party under any such License Agreement.

                                    (ii) Neither the Company nor any of its
          Subsidiaries have licensed or sublicensed its rights in any material
          Intellectual Property other than pursuant to the License Agreements.

                                    (iii) No royalties, honoraria or other fees
          are payable by the Company or any Subsidiary to any third parties for
          the use of or right to use any Intellectual Property except pursuant
          to the License Agreements.

                                    (iv) The Company or a Subsidiary owns, free
          and clear of all or Encumbrances, or, has a valid right to use, all of
          the Intellectual Property. The Company or a Subsidiary is listed in
          the records of the appropriate United States, state, or foreign
          registry as the sole current owner of record for each application and
          registration listed on Schedule 6.11(a). All proprietary Intellectual
          Property was either developed: (A) by employees of the Company or any
          Subsidiary within the scope of their employment, or (B) by independent
          contractors who have properly assigned all of their rights to the
          Company or any Subsidiary pursuant to written agreements.

                                    (v) The Intellectual Property owned by the
          Company or any Subsidiary and, to the Knowledge of the Company, any
          Intellectual Property used by the Company or any Subsidiary, is
          subsisting, in full force and effect, and has not been cancelled,
          expired, or abandoned, and, to the Knowledge of the Company is valid
          and enforceable.

                                    (vi) There is no pending or, to the
          Knowledge of the Company, threatened claim, suit, arbitration or other
          adversarial proceeding before any court, agency, arbitral tribunal, or
          registration authority in any jurisdiction involving the Intellectual
          Property owned by the Company or its Subsidiaries, or, to the
          Knowledge of the Company, the Intellectual Property licensed to the
          Company or any Subsidiary, alleging that the activities or the conduct
          of the Company's or any Subsidiary's businesses infringe upon, violate
          or constitute the unauthorized use of the intellectual property rights
          of any third party or challenging the Company's or any Subsidiary's
          ownership, use, validity, enforceability or registrability of any
          Intellectual Property. There are no settlements, forebearances to sue,
          consents, judgments, or orders or similar obligations other than the
          License Agreements which (i) restrict the Company's or any
          Subsidiary's right to use any Intellectual Property, (ii) restrict the
          Company's or any Subsidiary's businesses in order to accommodate a
          third party's intellectual property rights or (iii) permit third
          parties to use any Intellectual Property owned or controlled by the
          Company or any Subsidiary.

                                    (vii) To the Knowledge of the Company, the
          conduct of the Company's and any Subsidiary's business as currently
          conducted or contemplated to be conducted does not infringe upon
          (either directly or indirectly such as through contributory
          infringement or inducement to infringe) any intellectual property
          rights owned or controlled by any third party. To the Knowledge of the
          Company, no third party is misappropriating, infringing, diluting or
          violating any Intellectual Property owned or used by the Company or
          any Subsidiary and no such claims, suits, arbitrations or other
          adversarial proceedings have been brought or threatened against any
          third party by the Company or any Subsidiary.

                                    (viii) The Company and each Subsidiary take
          reasonable and prudent measures to protect the confidentiality of
          Trade Secrets, including requiring their employees, contractors and
          agents and other parties having access thereto to execute written
          non-disclosure agreements. To the Knowledge of the Company, no Trade
          Secret has been disclosed or authorized to be disclosed to any third
          party other than pursuant to a written non-disclosure agreement that
          adequately protects the Company's and the applicable Subsidiary's
          proprietary rights in and to such Trade Secrets. Schedule 6.11(c) set
          forth a list of each such written non-disclosure agreement. To the
          Knowledge of the Company, no party to any non-disclosure agreement
          relating to its Trade Secrets is in material breach or default
          thereof.

                                    (ix) No current or former stockholder,
          director, officer, employee, contractor, agent or consultant of the
          Company or any Subsidiary (or any of their respective predecessors in
          interest) will, after giving effect to the transactions contemplated
          herein, own or retain any rights to use any of the Intellectual
          Property owned or used by the Company or any Subsidiary.

                           (d) The transactions contemplated hereby will not
result in the loss or impairment of the Company's or any Subsidiary's right to
own or use any of the Intellectual Property, nor will it require the consent of
any Governmental Entity or third party in respect of any such Intellectual
Property.

                           (e) All Trademarks have been in continuous use by the
Company or its Subsidiaries, and the Trademarks listed in Schedule 6.11(a) for
which the Company or any Subsidiary has obtained or applied for a registration
have been continuously used in the form appearing in, and in connection with the
goods and services listed in, their respective registration certificates. To the
Knowledge of the Company or the Founders, there has been no prior use of such
Trademarks by any third party which would confer upon said third party superior
rights in such Trademarks. The Company and its Subsidiaries have adequately
policed the Trademarks against third party infringement so as to maintain the
validity of such Trademarks.

                  6.12 Foreign Corrupt Practices Act. Neither the Company nor
any Subsidiary, director, officer, agent, employee or other Person acting on
behalf of the Company or any Subsidiary has, in the course of his, her or its
actions for, or on behalf of, the Company or any Subsidiary, offered or made,
directly or indirectly through any other Person, any payments of anything of
value (in the form of a contribution, gift, entertainment or other expense), to
(a) any Person employed by, or acting in an official capacity on behalf of, any
Governmental Entity, or (b) any foreign or domestic government official,
political party or official of such party, or any candidate for political office
or employee thereof. Neither the Company, any Subsidiary, nor any director,
officer, agent, employee or other Person acting on behalf of the Company or any
Subsidiary has violated or is in violation of any provision of the U.S. Foreign
Corrupt Practices Act of 1977, as amended, or made any bribe, rebate, payoff,
influence payment, kickback or unlawful payment to any foreign or domestic
government or political party official, employee, appointee or candidate.

                  6.13 Material Contracts. Each material contract of the Company
and any of its Subsidiaries involving aggregate payments by or to the Company in
excess of $250,000 or with a term in excess of two (2) years is listed on
Schedule 6.13 hereof. Each such contract is the legal, valid and binding
obligation of the Company, enforceable against the Company and/or such
Subsidiary, as the case may be, in accordance with its terms, except to the
extent enforcement may be limited by: (a) bankruptcy, insolvency,
reorganization, moratorium or similar laws now or hereafter in effect relating
to creditors' rights generally, and (b) general principals of equity (regardless
of whether enforceability is considered in a proceeding at law or in equity).
There has not occurred any breach, violation or default or any event that, with
the lapse of time, the giving of notice or the election of any Person, or any
combination thereof, would constitute a breach, violation or default by the
Company or its Subsidiary, as the case may be, under any such contract or, to
the Knowledge of the Company or its Subsidiary or the Founders, as the case may
be, by any other Person to any such contract. Neither the Company nor any
Subsidiary has been notified that any party to any material contract intends to
cancel, terminate, not renew or exercise an option under any material contract,
whether in connection with the transactions contemplated hereby or otherwise.
The Company is not materially restricted by agreement from carrying on its
business anywhere in the world.

                  6.14 Voting and Registration Rights. Except for the Investor
Rights Agreement, there are no provisions of the certificate of incorporation or
the bylaws of the Company or any of its Subsidiaries, no agreements to which the
Company or any of its Subsidiaries is a party and no agreements by which the
Company, any of its Subsidiaries or the Securities are bound, which (a) may
affect or restrict the voting rights of the Purchaser with respect to the
Securities in its capacity as a stockholder of the Company, (b) restrict the
ability of the Purchaser, or any successor thereto or assignee or transferee
thereof, to transfer the Securities, (c) would adversely affect the Company's or
the Purchaser's right or ability to consummate the transactions contemplated by
this Agreement or comply with the terms of the Transaction Documents and the
transactions contemplated hereby or thereby, (d) require the vote of more than a
majority of the Company's issued and outstanding Common Stock, voting together
as a single class, to take or prevent any corporate action, other than those
matters requiring a class vote under Delaware law, or (e) entitle any party to
nominate or elect any director of the Company or require any of the Company's
stockholders to vote for any such nominee or other Person as a director of the
Company in each case, except as provided for in this Agreement. Except as
disclosed on Schedule 6.14, the Company is not under any obligation, contractual
or otherwise, to register for sale any of its securities under the Securities
Act.

                  6.15 Form S-3 Eligibility. The Company is currently eligible
under the eligibility requirements of General Instruction I to Registration
Statement on Form S-3 to register the resale of its Common Stock on a
registration statement on Form S-3 under the Securities Act. To the Knowledge of
the Company, there exist no facts or circumstances that would reasonably be
expected to prohibit or delay the preparation and filing of a registration
statement on Form S-3 with respect to the Purchased Shares and the Warrant
Shares in accordance with the terms of this Agreement and the Registration
Rights Agreement.

                  6.16 Issuances Exempt. Assuming the truth and accuracy of the
representations and warranties of the Purchaser contained in Section 5 hereof,
the offer, sale, and issuance of the Securities will be exempt from the
registration requirements of the Securities Act, and will have been registered
or qualified (or are exempt from registration and qualification) under the
registration, permit or qualification requirements of all applicable state
securities laws. All shares of capital stock and other securities issued by the
Company prior to the Closing Date have been issued in transactions either
registered under the Securities Act or exempt from the registration requirements
under the Securities Act and all applicable state securities or "blue sky" laws,
and in compliance with all applicable corporate laws. Except as set forth on
Schedule 6.16, the Company has not offered any of its capital stock, or any
other securities, for sale to, or solicited any offers to buy any of the
foregoing from the Company, or otherwise approached or negotiated with any other
Person in respect thereof, in such a manner as to require registration under the
Securities Act. No holder of any of the Company's capital stock has any
rescission rights.

<PAGE>

                  6.17 No Integrated Offering. Neither the Company, nor any of
its Affiliates or any other Person acting on the Company's behalf, has directly
or indirectly engaged in any form of general solicitation or general advertising
with respect to the Securities nor have any of such Persons made any offers or
sales of any security or solicited any offers to buy any security under
circumstances that would require registration of the Securities under the
Securities Act or cause this offering of Securities to be integrated with any
prior offering of securities of the Company for purposes of the Securities Act.

                  6.18 Absence of Certain Developments. Since December 31, 2006,
neither the Company nor its Subsidiaries have suffered any Material Adverse
Change. Since December 31, 2006, the Company and its Subsidiaries have conducted

                  6.19 No Undisclosed Liabilities. Schedule 6.18 sets forth an
accurate list of (a) all liabilities of the Company and its Subsidiaries in

SEC Documents (other than trade payables in the ordinary course of business),
and (b) all loan agreements, indemnity or guaranty agreements, bonds, mortgages,
liens, pledges or other security agreements to which the Company or any
Subsidiary is a party. Except as set forth on Schedule 6.19, since the date of

any liabilities of any kind, character and description, whether accrued,
absolute, secured or unsecured, contingent or otherwise other than (i)
liabilities or obligations incurred in the ordinary course of business, (ii)
liabilities or obligations that arise out of facts or events that are within the
scope of the subject matter of any other representation or warranty contained in
this Article 6 and such facts or events did not require disclosure by virtue of
any knowledge, time or materiality limitation contained in the relevant
representation or warranty and (iii) liabilities or obligations that
individually or in the aggregate would not reasonably be expected to result in a
Material Adverse Change with respect to the Company.

                  6.20 Litigation. Except as set forth on Schedule 6.20, there
is no claim, action, proceeding, lawsuit, inquiry, arbitration or investigation
before or by any court, public board, arbitrator, Governmental Entity including,
without limitation, the SEC or the National Association of Securities Dealers,
pending or, to the Knowledge of the Company, threatened against or affecting the
Company, any Subsidiary, or their respective properties or their respective
directors or officers in their capacities as such. To the Knowledge of the
Company, there are no facts which, if known by a potential claimant or
Governmental Entity, could reasonably be expected to give rise to a claim or
proceeding which, if asserted or conducted with results unfavorable to the
Company or any Subsidiary, is reasonably likely to result in a Material Adverse
Change with respect to the Company or is reasonably likely to prevent or
materially delay the consummation of the transactions contemplated hereby.
Neither the Company nor any Subsidiary is subject to any outstanding order,
ruling, judgment or decree that is reasonably likely to result in a Material
Adverse Change with respect to the Company or is reasonably likely to prevent or
materially delay the consummation of the transactions contemplated hereby.

                  6.21 Compliance with Laws. The business of the Company and its
Subsidiaries is not being conducted in violation of any law, ordinance or
regulation of any Governmental Entity, including without limitation, the SEC and
the NASD, except for violations that, either singly or in the aggregate, are not
reasonably likely to result in a Material Adverse Change with respect to the
Company. Neither the Company nor any Subsidiary has received notification from
any Governmental Entity, including without limitation, the SEC and the NASD, (a)
asserting a violation of any law, statute, ordinance or regulation or the terms
of any judgments, orders, decrees, injunctions or writs applicable to the
conduct of its business, (b) threatening to revoke any license, franchise,
permit or government authorization, or (c) restricting or in any way limiting
its operations as currently conducted or proposed to be conducted. Neither the
Company, nor to the Company's Knowledge, any of its officers, directors,
employees, affiliates or agents has violated any law, regulation, ordinance,
judgment, order or decree which is reasonably likely to give rise to the
initiation of an enforcement action by the SEC or NASD.

Company and each of its Subsidiaries has duly and timely filed (or has had duly
and timely filed on its behalf) with the appropriate taxing authorities all Tax
Returns required to be filed through the date hereof (after giving effect to any
valid extension of time in which to make such filings), and all such Tax Returns
are true, correct and complete in all material respects. The Company and each of
its Subsidiaries has paid on a timely basis all material Taxes due and payable.
Neither the Company nor any of its Subsidiaries is currently the beneficiary of

Subsidiaries does not file Tax Returns that it is or may be subject to taxation
by that jurisdiction.

                           (b) Audits, Investigations, Disputes or Claims. No
deficiencies for Taxes of the Company or any of its Subsidiaries have been

Subsidiaries by any taxing or other governmental authority that have not been
fully paid or finally settled, and adequate reserves or accruals in accordance
with GAAP have been established in the books of the Company and its Subsidiaries
with respect to any unpaid Taxes. There are no audits, investigations, disputes
or claims relating to the Taxes or Tax Returns of the Company or any of its
Subsidiaries currently being conducted or made by any taxing authority. Neither
the Company nor any of its Subsidiaries has executed a waiver with respect to
any statute of limitations relating to the assessment or collection of any
Taxes.

                           (c) Prior Affiliated Groups and Other Entity
Liability. Neither the Company nor any of its Subsidiaries has been a member of
an affiliated group of corporations within the meaning of Section 1504 of the

Subsidiaries has, in all material respects, withheld and paid all Taxes required
to have been withheld and paid in connection with amounts paid or owing to any
employee, independent contractor, creditor, stockholder or other third party and
has filed all material Tax Returns required to be filed with respect thereto.

                  6.23     Employee Relations.

                           (a) All bonus, deferred compensation, pension,
retirement, profit-sharing, thrift, savings, employee stock ownership, stock
bonus, stock purchase, restricted stock and stock option plans, employment or
severance contracts, health and medical insurance plans, life insurance and
disability insurance plans, other material employee benefit plans, contracts or

Subsidiaries including, but not limited to, "employee benefit plans" within the

or have terms requiring assumption or any guarantee by the Purchaser.

                                       17
<PAGE>

                           (b) There have been no violations of ERISA or the
Code relating to any Employee Benefit Plan that is reasonably likely to result
in a Material Adverse Change with respect to the Company relating to any
Employee Benefit Plan. The Company has timely filed all documents, notes and
reports (including IRS Form 5500) for each such Employee Benefit Plan with the
applicable Governmental Entities and has timely furnished all required documents
to the participants or beneficiaries of each such Employee Benefit Plans.

                           (c) Except as set forth on Schedule 6.23, the Company
and its Subsidiaries have no employment contracts with any of its employees not
expressly terminable at will and no collective bargaining agreements covering
any of its employees. Further, the Company and its Subsidiaries have no
policies, procedures or handbooks providing for other than at-will employment.
To the Knowledge of the Company, no employee of or consultant to the Company or
any Subsidiary is in material violation of any term of any employment contract
or any other contract or agreement relating to the relationship of any such
employee or consultant with the Company or any Subsidiary. The Company and each
Subsidiary have operated and administered all employee compensation and benefit
plans, programs and arrangements in accordance with their terms and with all
applicable laws in all material respects. To the Knowledge of the Company, no
key employee intends to terminate his or her employment with the Company or any
Subsidiary, nor does the Company or any Subsidiary have any present intention to
terminate the employment of any key employee.

                           (d) The Company and its Subsidiaries are not
delinquent in payments to any of their employees for any earned wages, salaries,
commissions, bonuses or other direct compensation for any services performed
through the date hereof or amounts required to be reimbursed to them to the date
hereof that are due and owing under federal, state or local law. The Company and
its Subsidiaries are in material compliance with all applicable federal, state
and local laws, rules and regulations respecting employment, employment
practices, labor, terms and conditions of employment and wages and hours. All
Persons treated by the Company and its Subsidiaries as independent contractors
for any purpose do satisfy and have satisfied the requirements of law to be so
treated, and the Company and its Subsidiaries have fully and accurately reported
the amounts paid by the Company and its Subsidiaries to or on behalf of such
persons on IRS Forms 1099 when required to do so. No individual who has
performed services for or on behalf of the Company and its Subsidiaries, and who
has been treated by the Company and its Subsidiaries as an independent
contractor, is classifiable as a "leased employee," within the meaning of
Section 414(n)(2) of the Code, with respect to the Company and its Subsidiaries
or with respect to any customer of the Company and its Subsidiaries. Neither the
Company nor any Subsidiary is bound by or subject to (and none of its assets or
properties is bound by or subject to) any written or oral, express or implied,
commitment or arrangement with any labor union, and, to the Knowledge of the
Company, no labor union has requested or has sought to represent any of the
employees, representatives or agents of the Company or any Subsidiary. There is
no labor strike, dispute, slowdown or stoppage actually pending or, to the
Knowledge of the Company, threatened against or involving the Company or any
Subsidiary. There are no suits, actions, disputes, claims (other than routine
claims for benefits), investigations or audits pending or, to the Knowledge of
the Company, threatened in connection with any Employee Benefit Plan, but
excluding any of the foregoing which is not reasonably likely to result in a
Material Adverse Change with respect to the Company or any Subsidiary.

<PAGE>

                           (e) No director or officer or other employee of the
Company or any Subsidiary will become entitled to any retirement, severance or
similar benefit or enhanced or accelerated benefit (including any acceleration
of vesting or lapse of repurchase rights or obligations with respect to any
Employee Benefit Plan) solely as a result of the transactions contemplated in
this Agreement; and no payment made or to be made to any current or former
employee or director of the Company or any of its Affiliates by reason of the
transactions contemplated hereby (whether alone or in connection with any other

         9. Covenants of the Company. The Company agrees that the Company (and
each of its Subsidiaries unless the context otherwise requires) will use
commercially reasonable efforts to do the following:

                  9.1 Maintain Corporate Rights and Facilities. The Company
shall maintain and preserve its corporate existence and all rights, franchises,
licenses, Intellectual Property and other authority reasonably deemed adequate
by the Company for the conduct of its business; maintain its properties,
equipment and facilities in good order and repair; and conduct its business in

force and effect a policy or policies of insurance, including, without
limitation, a directors and officers liability insurance policy, issued by
insurers of recognized responsibility, insuring it, its directors and officers,
its properties and its business against such losses and risks, and in such
amounts, as are customary in the case of corporations of established reputation
engaged in the same or a similar business.

                  9.3 Notice of Litigation, Disputes and Adverse Changes; Other
Information. The Company shall promptly notify the Purchaser of (i) each legal
action, suit, arbitration or other administrative or governmental investigation
or proceeding (whether federal, state, local or foreign) instituted or, to the
Knowledge of the Company, threatened against the Company (or of any occurrence
or dispute which involves a reasonable likelihood of any such action, suit,
arbitration, investigation or proceeding being instituted), or (ii) any other
occurrence or change of circumstance relating to the Company which, in either
such case, could reasonably be expected to materially and adversely affect the
Company's condition (financial or otherwise), properties, assets, liabilities,
business, prospects or operations (except for any changes that are the effect or
result of economic factors generally affecting the economy as a whole).

                  9.4 Internal Accounting Controls. The Company shall maintain a
system of internal accounting controls administered in accordance with Section

shall reimburse all directors of the Company for their reasonable out-of-pocket
expenses in connection with attending meetings of the Company's Board of
Directors and all committees thereof and all reasonable out-of-pocket expenses

certificate of incorporation, or the Company's bylaws if no provisions in the
certificate of incorporation relate to directors' liability or indemnification,
shall at all times (i) eliminate the liabilities of directors to the maximum
extent permitted by the law and (ii) require the indemnification of all of the

keep available out of its authorized but unissued Common Stock the number of
shares required from time to time for issuance upon the exercise of the Warrant
(including any additional shares which may become so issuable by reason of the

any transfer or other disposition on the stock record books of the Company or
otherwise effect the transfer or other disposition of any shares of capital
stock or other securities (whether debt or equity securities) of the Company
which have been transferred or otherwise disposed of in a manner not in

approval of the Purchaser.

         NON-COMPETITION AGREEMENT (this "Agreement") dated as of April 10,
2007, by and between Optionable, Inc. a Delaware corporation (the "Company") and
Edward O'Connor (the "Restricted Party").

         WHEREAS, the Company and the Restricted Party are parties to a Stock
and Warrant Purchase Agreement, dated as of April 10, 2007, (the "Stock and
Warrant Purchase Agreement") among the Company, the Restricted Party (through
Ridgecrest Capital, Inc., a New York Corporation), Kevin Cassidy (through
Pierpont Capital, Inc., a New York Corporation), Mark Nordlicht, an individual,
and NYMEX Holdings, Inc. ("NYMEX");

         WHEREAS, pursuant to the Stock and Warrant Purchase Agreement, NYMEX
will make a significant investment in the Company through the purchase of shares
of Common Stock of the Company from the Restricted Party, Kevin Cassidy and Mark
Nordlicht and the purchase of a warrant from the Company;

         WHEREAS, the Restricted Party has valuable knowledge and expertise with
respect to the business of the Company and its Confidential Information (as
defined in Section 2 below) which, if used to compete against the Company, would
have a material adverse effect on the Company;

         WHEREAS, in recognition of the Restricted Party's knowledge and
expertise, NYMEX has requested that the Restricted Party enter into a
non-competition agreement with the Company as an inducement to, and condition
of, NYMEX's agreement to make its investment in the Company;

         WHEREAS, it is a condition of NYMEX's obligation to close the
transactions contemplated by the Stock and Warrant Purchase Agreement that the
Company and the Restricted Party have entered into this Agreement; and

         WHEREAS, the Restricted Party will receive, directly and indirectly,
substantial and valuable consideration upon the consummation of the transactions
contemplated in the Stock and Warrant Purchase Agreement;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants, agreements and understandings contained herein and for good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto agree as follows:

         1. Definitions. Capitalized terms used herein without being otherwise
defined shall have the meanings assigned to them in the Stock and Warrant
Purchase Agreement.

<PAGE>

         2. Restrictive Covenants. The Restricted Party acknowledges that the
business in which the Company is engaged is intensely competitive and: (i) by
reason of the Restricted Party's appointment and duties, he is privy to
substantial and vital confidential information of the Company, not generally
published or available to the public, concerning the organization, business and
affairs, products and technology, and customers of the Company, including but
not limited to, business plans, operational methods, financial information and
projections, technical processes and data, product development plans, research
and development, lists of customers, interests and needs of customers, business
plans and policies, overhead and cost information, profit margins, pricing
methods or prices considered or actually charged, lists and records of sales and
contracts, computer software applications and other programs, source codes,
object codes, marketing techniques and materials, marketing and development
plans, price lists, pricing policies, personnel information and other trade
secrets (the "Confidential Information"); (ii) the disclosure of any of the
foregoing to existing or potential competitors of the Company would place the
Company at a serious competitive disadvantage and could do serious damage to the
business of the Company; (iii) by the Restricted Party's training, experience
and expertise, the Restricted Party's services to the Company are extraordinary,
special and unique; (iv) the purposes of the covenants in this Agreement are to
protect the goodwill and Confidential Information of the Company; and (v) NYMEX
has required that the Restricted Party enter into this Agreement as a condition
to its agreement to make its investment in the Company and NYMEX would not close
the transactions contemplated by the Stock and Warrant Purchase Agreement
without the Restricted Party agreeing to be bound by this Agreement.
Accordingly, the Restricted Party willingly agrees to be bound by the following
restrictions :

                  (a) During the course of the Restricted Party's employment
         with the Company and at all times after the termination of the
         Restricted Party's employment with the Company for any reason, the
         Restricted Party shall not, directly or indirectly, whether
         individually, as an officer, director, employee, consultant, owner,
         investor, partner or stockholder of any business, or in any other
         capacity, make known, disclose, furnish, make available or utilize any
         of the Confidential Information, other than in the proper performance
         of the duties contemplated herein. The Restricted Party agrees to
         return all Confidential Information, including all photocopies,
         extracts and summaries thereof, and any such information stored
         electronically or in any other manner to the Company at any time upon
         request by the Company and upon the termination of the Restricted
         Party's employment for any reason. Nothing contained in this Section
         2(a) shall be deemed to preclude the Restricted Party from: (i) using
         his own general skills, knowledge and experience; (ii) using or
         disclosing any Confidential Information which becomes public through no
         fault of the Restricted Party; or (ii) disclosing Confidential
         Information pursuant to subpoena, court order or legal process,
         provided that the Restricted Party gives the Company advance written
         notice of the required disclosure so that the Company may, if it
         wishes, seek an appropriate protective order.

                  (b) During the course of the Restricted Party's employment
         with the Company and for a period of nine (9) months following the
         termination of the Restricted Party's employment with the Company for
         any reason (the "Non-Competition Period"), the Restricted Party shall
         not, directly or indirectly, whether as officer, director, employee,
         consultant, owner, investor, partner or stockholder, be engaged in or
         have any financial interest in (other than an interest of less than
         five percent (5%) of the stock of a publicly traded company) or
         affiliation with or render any services to or for any person, firm,
         company or organization which provides "Competitive Services" (as
         defined below) to brokerage firms, other financial institutions
         providing energy brokerage services or clearinghouses, anywhere in the
         United States, it being understood and acknowledged by the Restricted
         Party that the Company conducts business and offers Competitive
         Services on a nationwide basis. The term Competitive Services shall
         mean natural gas and other energy brokerage services. Notwithstanding
         the foregoing, it shall not be a violation of this Section 2(b) for the
         Restricted Party to become an officer, director, employee, consultant,
         owner, investor, partner or stockholder of any person, firm, company or
         organization which provides "Competitive Services" if, and only if, the
         Restricted Party's primary responsibilities to or for such person,
         firm, company or organization do not involve, and do in any significant
         manner relate to, providing Competitive Services to brokerage firms,
         other financial institutions providing energy brokerage services or
         clearinghouses, anywhere in the United States.

<PAGE>

                  (c) During the Non-Competition Period, the Restricted Party
         shall not, directly or indirectly, for his benefit or for the benefit
         of any person, firm or entity (other than the Company):

                           (i) cause or attempt to cause any Customer (as
                  defined below) or Prospective Customer (as defined below) of
                  the Company on whom the Restricted Party called or with whom
                  the Restricted Party became acquainted during employment with
                  the Company to obtain Competitive Services from any person,
                  firm, company or organization other than the Company or to
                  cease doing business with, or reduce the amount of Competitive
                  Services obtained from, the Company. For purposes of this
                  Agreement, "Customer" shall mean any brokerage firm, financial
                  institution, energy trader, hedge fund or other entity which
                  was a customer of or had an account with the Company during
                  the one (1) year period preceding the Restricted Party's
                  termination of employment for any reason. For purposes of this
                  Agreement, "Prospective Customer" shall mean any brokerage
                  firm, financial institution, energy trader, hedge fund or
                  other entity for which the Company had submitted a written
                  proposal to provide services within the one (1) year period
                  preceding the Restricted Party's termination of employment for
                  any reason (including the expiration of the Term); or

                           (ii) enter into any partnership, limited liability
                  company, corporation, new or joint venture or similar
                  arrangement with, or hire or retain or attempt to hire or
                  retain, any person who is, or at any time during the one (1)
                  year period preceding the termination of the Restricted
                  Party's employment with the Company for any reason, was an
                  employee of or consultant to the Company, without the prior
                  written consent of the Company, such consent to be within the
                  Company's sole and absolute discretion.

                  (d) The Restricted Party acknowledges that the restrictions
         specified in this Section 2 are reasonable in view of the nature of the
         business in which the Company is engaged, the Restricted Party's
         position with the Company, and the Restricted Party's knowledge of the
         Company's business, and that any breach of this Section 2 may cause the
         Company irreparable harm for which there is no adequate remedy at law,
         and as a result of this, the Company will be entitled to seek the
         issuance by a court of competent jurisdiction of an injunction,
         restraining order or other equitable relief in favor of the Company,
         without the necessity of posting a bond, restraining the Restricted
         Party from committing or continuing to commit any such violation. Any
         right to obtain an injunction, restraining order or other equitable
         relief hereunder will not be deemed to be a waiver of any right to
         assert any other remedy the Company may have at law or in equity.

                  (e) The Restricted Party acknowledges and agrees that the
         duration and geographic scope of the covenants contained in this
         Section 2 are fair and reasonable. Accordingly, the Restricted Party
         agrees that, in the event that any of the covenants contained in this
         Section 2 is nevertheless judicially determined to be unenforceable
         because of the duration or geographic scope thereof, the court making
         such determination is hereby directed to reduce such duration and/or
         scope to the extent necessary to enable such court to determine that
         such covenant is reasonable and enforceable, and to enforce such
         covenant as so amended.

                  (f) The provisions of this Section 2 shall survive the
         termination of the Restricted Party's employment for any reason.

         3. Notices. Any notice, request, instruction or other document to be
given hereunder by any party hereto to the other party shall be in writing and
shall be given (and will be deemed to have been duly given upon receipt) by
delivery in person, by electronic facsimile transmission, cable, telegram, telex
or other standard forms of written telecommunications, by overnight courier or
by registered or certified mail, postage prepaid,

         4. Binding Effect; Assignment. This Agreement shall be binding upon and
shall inure to the benefit of the Company and its successors and assigns. This
Agreement shall be binding upon the Restricted Party. Neither this Agreement nor
any right or interest hereunder shall be assignable or transferable by the

         5. Modification and Waiver. No provision of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in writing and signed by the Restricted Party and the Company.

         6. Entire Agreement. This Agreement sets forth the entire understanding
of the parties hereto with respect to the subject matter hereof and supersedes
all prior or contemporaneous agreements, written or oral, between them as to
such subject matter.

         7. Headings. The headings contained herein are solely for the purpose
of reference, are not part of this Agreement and shall not in any way affect the
meaning or interpretation of this Agreement.

         8. Severability. In the event that any one or more of the provisions
contained in this Agreement or in any other instrument referred to herein,
shall, for any reason, be held to be invalid, illegal or unenforceable in any
respect, then to the maximum extent permitted by law, such invalidity,
illegality or unenforceability shall not affect any other provision of this
Agreement or any other such instrument. Furthermore, in lieu of any such invalid
or unenforceable term or provision, the parties hereto intend that there shall
be added as a part of this Agreement a provision as similar in terms to such
invalid or unenforceable provision as may be possible and be valid and
enforceable. If any of the covenants of this Agreement are held to be
unreasonable, arbitrary, or against public policy, such covenants will be
considered divisible with respect to scope, time, and geographic area, and in
such lesser scope, time and geographic area, will be effective, binding and
enforceable against the Restricted Party.

         9. Counterparts; Facsimile Execution. This Agreement may be executed in
one or more counterparts, all of which taken together shall constitute one and
the same instrument. Any counterpart or other signature to this Agreement that
is obtained by facsimile shall be deemed for all purposes as constituting good
and valid execution and delivery by such party of this Agreement and shall be as
effective as delivery of an original counterpart.

         10. Governing Law; Jurisdiction.

                  (a) This Agreement and the legal relations between the parties
         hereto shall be governed by and construed in accordance with the laws
         of the State of New York, without regard to its conflict of laws rules.

                  (b) Each of the parties hereto hereby irrevocably and
         unconditionally consents to submit to the exclusive jurisdiction of the
         courts of the State of New York and the United States of America
         located in the State of New York (the "New York Courts") for any action
         or proceeding arising out of or relating to this Agreement and the
         transactions contemplated hereby (and agrees not to commence any action
         or proceeding relating thereto except in such courts), and further
         agrees that service of any process, summons, notice or document by U.S.
         registered mail to his or its respective address set forth in Section 3
         hereof shall be effective service of process for any action or

                                       5
<PAGE>

         proceeding brought against it in any such court. Nothing herein shall
         in any way be deemed to limit the ability of any party hereto (i) to
         serve any such legal process, summons, notices and documents in any
         other manner permitted by applicable law, (ii) to obtain jurisdiction
         over the other parties hereto in such other manner, as may be permitted
         by applicable law, or (c) to bring any action or proceeding for
         enforcement of a judgment entered by a New York Court in any other
         jurisdiction. Each of the parties hereto hereby irrevocably and
         unconditionally waives any objection to the laying of venue of any
         action or proceeding arising out of this Agreement or the transactions
         contemplated hereby in a New York Court, and hereby further irrevocably
         and unconditionally waives and agrees not to plead or claim in any such
         court that any such action or proceeding brought in any such court has
         been brought in an inconvenient forum.

         "Withdrawn Demand Registration" has the meaning set forth in Section
2(g) hereof.

         2.       Demand Registrations.

         (a) Right to Request Registration. Any time after the date hereof, the
Stockholder and/or one or more of its permitted transferees (the "Initiating
Holder(s)") may request registration under the Securities Act in an underwritten
offering of all or part of the Registrable Common Stock or an underwritten take
down off of an existing, effective shelf registration statement of all or part
of the Registrable Common Stock (each, a "Demand Registration"); provided that
(i) the anticipated offering price of each Demand Registration is at least
$5,000,000 and (ii) the Company shall not be obligated to effectuate more than
one underwritten offering pursuant to a Demand Registration in any six-month
period, unless any or all of the shares included in the first Demand
Registration statement, including any such shares included in an underwritten
take down off of an existing, effective shelf registration statement, remain
unsold. In connection with each such Demand Registration, the Company shall
cause there to occur Full Cooperation. Each request for a Demand Registration
shall state the number of shares of Registrable Common Stock proposed to be sold
and the intended methods of disposition thereof.

         Within ten days after receipt of any such request for Demand
Registration, the Company shall give written notice of such request to all other
Holders of Registrable Common Stock and shall, subject to the provisions of
Section 2(d) hereof, include in such registration all such Registrable Common
Stock with respect to which the Company has received written requests for
inclusion therein within 15 days after the receipt of the Company's notice.

         (b) Number of Demand Registrations. Subject to the provisions of
Section 2(a) hereof, the Holders of Registrable Common Stock shall be entitled
to request an aggregate of two Demand Registrations. A registration shall not
count as one of the permitted Demand Registrations (i) until it has become
effective, (ii) if the Initiating Holder is not able to register at least 50% of
the Registrable Common Stock requested by such Initiating Holder to be included
in such Demand Registration, (iii) in the case of a Demand Registration that
would be the last permitted Demand Registration requested hereunder, if the
Initiating Holder is not able to register all of the Registrable Common Stock
requested to be included by the Initiating Holder in such Demand Registration,
or (iv) if there is not Full Cooperation in connection therewith.

         (c) Priority on Demand Registrations. Except as provided in Section
2(g) hereof, the Company shall not include in any Demand Registration any
securities which are not Registrable Common Stock without the written consent of
the Holders of a majority of the shares of Registrable Common Stock to be
included in such registration, and without the written consent of the managing
underwriters. If the managing underwriters of the requested Demand Registration
advise the Company in writing that in their opinion the number of shares of
Registrable Common Stock proposed to be included in any such Demand Registration
exceeds the number of shares which can be sold in such offering and/or that the
number of shares of Registrable Common Stock proposed to be included in any such
Demand Registration would adversely affect the price per share of the Company's
equity securities to be sold in such offering, the Company shall include in such
Demand Registration only the number of shares of Registrable Common Stock which
in the opinion of such managing underwriter(s) can be sold. If the number of
shares which can be sold is less than the number of shares of Registrable Common
Stock proposed to be registered or sold in the Demand Registration, the amount
of Registrable Common Stock to be so sold shall be allocated (i) first, to the
shares of Registrable Common Stock requested to be registered by the Initiating
Holders, and (ii) second, pro rata among the other Holders of Registrable Common
Stock desiring to participate in such Demand Registration on the basis of the
amount of such Registrable Common Stock initially proposed to be registered or
sold off of an existing, effective shelf registration statement by such other
Holders.

                                       4

         (d) Restrictions on Demand Registrations. If the Company's Board of
Directors, in its good faith judgment, determines that any Demand Registration
should not be made or continued because (i) it would interfere with any material
financing, acquisition, corporate reorganization or merger or other material
transaction involving the Company or (ii) it would result in premature
disclosure of a matter the Company's Board of Directors has determined would not
be in the best interest of the Company to be disclosed at such time, the Company
may postpone the filing of a registration statement or, in case a registration
statement has been filed, may cause such registration statement to be withdrawn,
for up to 90 days; provided, however, that in no event shall the Company
withdraw a Registration Statement after such Registration Statement has been
declared effective; and provided, further, however, that in any of the events
described above, the Initiating Holder requesting such Demand Registration shall
be entitled to withdraw such request and, if such request is withdrawn, such
Demand Registration shall not count as one of the permitted Demand
Registrations. Notwithstanding the foregoing, for the duration of any such
withdrawal or postponement period, the Company shall use commercially reasonable
efforts to continue to prepare such Registration Statement and any related
materials so that the Company will be in a position to file such Registration
Statement when the withdrawal or postponement period shall have expired. The
Company shall provide written notice to the Initiating Holder requesting such
Demand Registration of (x) any postponement or withdrawal of the filing or
effectiveness of a Registration Statement pursuant to this Section 2(d) hereof,
(y) the Company's decision to file or seek effectiveness of such Registration
Statement following such withdrawal or postponement and (z) the effectiveness of
such Registration Statement. The Company may defer the filing of a particular
Registration Statement pursuant to this Section 2(d) hereof only once during any
twelve-month period.

         (e) Selection of Underwriters. The Initiating Holder(s) shall have the
right to select the managing underwriter(s) to administer the underwritten
offering made pursuant to any Demand Registration subject to the approval of the
Company, which will not be unreasonably withheld.

         (f) Other Registration Rights. The Company shall not grant to any
Person the right, other than as set forth herein and except to employees of the
Company with respect to registrations on Form S-8 (or any successor forms
thereto), to request the Company to register any securities of the Company
except such rights as are not more favorable than or inconsistent with the
rights granted to the Holders herein. In the event the Company grants rights
which are more favorable, the Company will make such provisions available to the
Holders and will enter into any amendments necessary to confer such rights on
the Holders. No Person, other than as set forth herein, shall be permitted to
exercise piggyback or other similar registration rights in any Demand
Registration unless all of the shares of Registrable Common Stock requested to
be registered by the Initiating Holders are included on such Demand
Registration.

                                       5

         (g) Effective Period of Demand Registrations. After any Demand
Registration filed pursuant to this Agreement has become effective or after a
final Prospectus relating to an underwritten take down off of an existing,
effective shelf registration statement has been filed, the Company shall use its
commercially reasonable efforts to keep such Demand Registration effective
(including any shelf registration statement supplemented by a prospectus
supplement) for a period of at least 120 days from the date on which the SEC
declares such Demand Registration effective or, in the case of an underwritten
take down off of an existing, effective shelf registration statement, from the
date of filing of the final Prospectus (if such Demand Registration is not
effective during any period within such 120 days, such 120-day period shall be
extended by the number of days during such period when such Demand Registration
is not effective) or, if earlier, until all of the Registrable Common Stock
covered by such Demand Registration has been sold. If the Company shall withdraw
any Demand Registration pursuant to Section 2(d) hereof (a "Withdrawn Demand
Registration"), the Initiating Holder of the Registrable Common Stock remaining
unsold and originally covered by such Withdrawn Demand Registration shall be
entitled to a replacement Demand Registration which (subject to the provisions
of this Section 2) the Company shall use its commercially reasonable efforts to
keep effective for a period commencing on the effective date of such Demand
Registration or, in the case of an underwritten take down off of an existing,
effective shelf registration statement, from the date of filing of the final
Prospectus, and ending on the earlier to occur of the date (i) which is 120 days
from the effective date of such Demand Registration or, in the case of an
underwritten take down off of an existing, effective shelf registration
statement, from the date of filing of the final Prospectus and (ii) on which all
of the Registrable Common Stock covered by such Demand Registration has been
sold. Such additional Demand Registration otherwise shall be subject to all of
the provisions of this Agreement.

         3. Piggyback Registrations.

         (a) Right to Piggyback. Whenever the Company proposes to register any
of its common equity securities on a registration statement (the "Piggyback
Registration Statement") under the Securities Act (other than a registration
statement on Form S-8 or on Form S-4 or any similar successor forms thereto) or
to effectuate a take down off of an existing, effective shelf registration
statement, whether for its own account or for the account of one or more
stockholders of the Company, and the registration form to be used may be used
for any registration of Registrable Common Stock (a "Piggyback Registration"),
the Company shall give written notice to all Holders at least 10 Business Days
prior to the initial filing of such Piggyback Registration Statement or
Prospectus relating to an underwritten take down off of an existing, effective
shelf registration statement or the date of the commencement of any such
offering of its intention to effect such sale or registration and, subject to
Sections 3(b) and 3(c) hereof, shall include in such Piggyback Registration
Statement or Prospectus all Registrable Common Stock of the same class of the
securities that are being registered and that are the subject of the offering
with respect to which the Company has received a written request from a Holder
for inclusion therein within 5 Business Days after the date of the Company's
notice. The Company may postpone or withdraw the filing or the effectiveness of
a Piggyback Registration at any time in its sole discretion.

                                       6
<PAGE>

         (b) Priority on Primary Registrations. If a Piggyback Registration is
an underwritten primary registration on behalf of the Company, and the managing
underwriters advise the Company in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number of
securities which can be sold in such offering and/or that the number of shares
of Registrable Common Stock proposed to be included in any such registration
would adversely affect the price per share of the Company's equity securities to
be sold in such offering, the Company shall include in such registration (i)
first, the securities the Company proposes to sell, and (ii) second, the
Registrable Common Stock requested to be included therein by the Holders, and
other securities requested to be included in such registration pro rata among
the Holders and the holders of such securities on the basis of the number of
shares requested to be registered by the Holders and such holders or as the
Holders and such other holders may otherwise agree.

         (c) Priority on Secondary Registrations. If a Piggyback Registration is
an underwritten secondary registration on behalf of a holder of the Company's
securities other than Registrable Common Stock, and the managing underwriters
advise the Company in writing that in their opinion the number of securities
requested to be included in such registration exceeds the number which can be
sold in such offering and/or that the number of shares of Registrable Common
Stock proposed to be included in any such registration would adversely affect
the price per share of the Company's equity securities to be sold in such
offering, the Company shall include in such registration (i) first, the
securities requested to be included therein by the holders requesting such
registration pro rata among the holders of such securities on the basis of the
number of shares requested to be registered by such holders, (ii) second, the
Registrable Common Stock requested to be included in such registration pro rata
among the Holders thereof on the basis of the number of shares requested to be
registered by such Holders and (iii) third, other securities requested to be
included in such registration pro rata among the holders of such securities on
the basis of the number of shares requested to be registered by such holders or
as such holders may otherwise agree.

         (d) Selection of Underwriters. If any Piggyback Registration is an
underwritten primary offering, the Company shall have the right to select the
managing underwriter or underwriters to administer any such offering.

         4. S-3 Registrations.

         If at any time that the Company is eligible to use Form S-3 or any
successor thereto, the Initiating Holder requests that the Company file a
Registration Statement on Form S-3 or any successor thereto for a public
offering of all or any portion of the Registrable Common Stock held by such
Holders, then the Company shall use its commercially reasonable efforts to
register under the Securities Act on Form S-3 or any successor thereto (an "S-3
Registration"), for public sale in accordance with the method of disposition
specified in such notice, the number of shares of Registrable Common Stock
specified in such notice; provided, however, that (i) no more than two such S-3
Registrations shall be required in any 12 month period and (ii) the Company
shall have no obligation to register such shares of Registrable Common Stock
pursuant to this Section 4 if (based on current market prices) the number of
shares of Registrable Common Stock specified in such notice would not yield
gross proceeds to the selling stockholders of at least $5,000,000. An S-3
Registration shall not count as a Demand Registration, unless such registration
is for an underwritten offering or an underwritten take down off of an existing,
effective shelf registration statement, in which case it shall be subject to the
provisions of Section 2 hereof to count as a Demand Registration.

                                       7
<PAGE>

         Whenever the Company is required by this Section 4 to use its
commercially reasonable efforts to effect the registration of Registrable Common
Stock on Form S-3, each of the procedures and requirements of Section 2 hereof
(including but not limited to the requirement that the Company notify all
Holders from whom notice has not been received and provide them with the
opportunity to participate in the offering) shall apply to such registration.
The Company shall maintain the effectiveness of any such S-3 Registration until
the earlier of the date on which (i) all of the Registrable Common Stock
included thereon has been sold, and (ii) all of the Registrable Common Stock may
be sold without restriction or limitation pursuant to Rule 144(k) under the
Securities Act. There is no limitation on the number of registrations pursuant
to this Section 4 that the Company is obligated to effect.

         5.       Holdback Agreements.

         The Company agrees not to effect any sale or distribution of any of its
equity securities during the 10 days prior to and during the 90 days beginning
on the effective date of any underwritten Demand Registration or any
underwritten Piggyback Registration or the date of the filing of a final
Prospectus relating to an underwritten take down off of an existing, effective
shelf registration statement (except as part of such underwritten registration
or pursuant to registrations on Form S-8 or S-4 or any successor forms thereto)
unless the underwriters managing the offering otherwise agree to a shorter
period or request a longer period, such period not to exceed 180 days; provided,
however, that in no event will the Company be required not to sell or distribute
its equity securities for more than an aggregate of 270 days in any period of
360 consecutive days solely as a result of any Demand Registration of NYMEX, not
including any holdback agreements relating to any other offering whether or not
NYMEX participates.

         6.       Registration Procedures.

         (a) Whenever the Holders request that any Registrable Common Stock be
registered or sold in an underwritten take down off of an existing, effective
shelf registration statement, each pursuant to this Agreement, the Company shall
use its commercially reasonable efforts to effect the registration or the filing
of the Prospectus, as applicable, and the sale of such Registrable Common Stock
in accordance with the intended methods of disposition thereof, and pursuant
thereto the Company shall as expeditiously as possible, but in no event later
than 60 days after any such request:

                                       8
<PAGE>

                           (i) prepare and file with the SEC a Registration
                  Statement with respect to such Registrable Common Stock and
                  use its commercially reasonable efforts to cause such
                  Registration Statement to become effective as soon as
                  practicable thereafter, but in no event later than 45 days
                  after the filing of such Registration Statement, in the case
                  of an S-3 Registration and 90 days after the filing of such
                  Registration Statement in the case of a Registration Statement
                  on Form S-1; and before filing a Registration Statement or
                  Prospectus or any amendments or supplements thereto, furnish
                  to the Holders of Registrable Common Stock covered by such
                  Registration Statement and the underwriter or underwriters, if
                  any, copies of all such documents proposed to be filed,
                  including documents incorporated by reference in the
                  Prospectus and, if requested by such Holders, the exhibits
                  incorporated by reference, and such Holders shall have the
                  opportunity to object to any information pertaining to such
                  Holders that is contained therein and the Company will make
                  the corrections reasonably requested by such Holders with
                  respect to such information prior to filing any Registration
                  Statement or amendment thereto or any Prospectus or any
                  supplement thereto;

                           (ii) prepare and file with the SEC such amendments
                  and supplements to such Registration Statement and the
                  Prospectus used in connection therewith as may be necessary to
                  keep such Registration Statement effective for a period of not
                  less than (A) in the case of a Demand Registration, 120 days,
                  or (B) in the case of an S-3 Registration, the earlier of the
                  date on which (i) all of the Registrable Common Stock included
                  thereon has been sold, and (ii) all of the Registrable Common
                  Stock may be sold without restriction or limitation pursuant
                  to Rule 144(k) under the Securities Act, or, in the case of
                  each of (A) or (B) above, such shorter period as is necessary
                  to complete the distribution of the securities covered by such
                  Registration Statement and comply with the provisions of the
                  Securities Act with respect to the disposition of all
                  securities covered by such Registration Statement during such
                  period in accordance with the intended methods of disposition
                  by the sellers thereof set forth in such Registration
                  Statement;

                           (iii) furnish to each seller of Registrable Common
                  Stock such number of copies of such Registration Statement,
                  each amendment and supplement thereto, the Prospectus included
                  in such Registration Statement (including each preliminary
                  Prospectus) and such other documents as such seller may
                  reasonably request in order to facilitate the disposition of
                  the Registrable Common Stock owned by such seller;

                           (iv) use its commercially reasonable efforts to
                  register or qualify such Registrable Common Stock under such
                  other securities or blue sky laws of such jurisdictions as any
                  seller of Registrable Common Stock reasonably requests and do
                  any and all other acts and things which may be reasonably
                  necessary or advisable to enable such seller to consummate the
                  disposition in such jurisdictions of the Registrable Common
                  Stock owned by such seller (provided, that the Company will
                  not be required to (A) qualify generally to do business in any
                  jurisdiction where it would not otherwise be required to
                  qualify but for this subparagraph (iv), (B) subject itself to
                  taxation in any such jurisdiction or (C) consent to general
                  service of process in any such jurisdiction);

                           (v) notify each seller of such Registrable Common
                  Stock, at any time when a Prospectus relating thereto is
                  required to be delivered under the Securities Act, of the
                  occurrence of any event as a result of which the Prospectus
                  included in such Registration Statement contains an untrue
                  statement of a material fact or omits to state any material
                  fact necessary to make the statements therein not misleading,
                  and, at the request of any such seller, the Company shall
                  prepare a supplement or amendment to such Prospectus so that,
                  as thereafter delivered to the purchasers of such Registrable
                  Common Stock, such Prospectus shall not contain an untrue
                  statement of a material fact or omit to state any material
                  fact necessary to make the statements therein not misleading;

                           (vi) in the case of an underwritten offering, enter
                  into such customary agreements (including underwriting
                  agreements in customary form) and take all such other actions
                  as are prudent and reasonable in order to expedite or
                  facilitate the disposition of such Registrable Common Stock
                  (including, without limitation, making members of senior
                  management of the Company available to participate in, and
                  cause them to cooperate with the underwriters in connection
                  with, "road-show" and other customary marketing activities
                  (including one-on-one meetings with prospective purchasers of
                  the Registrable Common Stock)) organized by the managing
                  underwriter and cause to be delivered to the underwriters and
                  the sellers, if any, opinions of counsel to the Company in
                  customary form, covering such matters as are customarily
                  covered by opinions for an underwritten public offering as the
                  underwriters may request and addressed to the underwriters and
                  the sellers;

                           (vii) make available, at reasonable times for
                  inspection by any seller of Registrable Common Stock, any
                  underwriter participating in any disposition pursuant to such
                  Registration Statement, any attorney, accountant or other
                  agent retained by the underwriter and one counsel retained by
                  Holders holding a majority of the Registrable Common Stock
                  being registered in such registration ("Holders' Counsel"),
                  all financial and other records, pertinent corporate documents
                  and properties of the Company, and cause the Company's
                  officers, directors, employees and independent accountants to
                  supply all information reasonably requested by any such
                  seller, underwriter, attorney, accountant, agent or Holders'
                  Counsel in connection with such Registration Statement;

                           (viii) use its commercially reasonable efforts to
                  cause all such Registrable Common Stock to be listed on each
                  securities exchange on which securities of the same class
                  issued by the Company are then listed or, if no such similar
                  securities are then listed, on the OTC Bulletin Board or on
                  Nasdaq or such other national securities exchange selected by
                  the Company;

                           (ix) provide a transfer agent and registrar for all
                  such Registrable Common Stock not later than the effective
                  date of such Registration Statement;

                                       10

                           (x) if requested, cause to be delivered, immediately
                  prior to the effectiveness of the Registration Statement (and,
                  in the case of an underwritten take down off of an existing,
                  effective shelf registration statement, at the time of the
                  pricing and the delivery of any Registrable Common Stock sold
                  pursuant thereto), letters from the Company's independent
                  certified public accountants addressed to each selling Holder
                  (unless such selling Holder does not provide to such
                  accountants the appropriate representation letter required by
                  rules governing the accounting profession) and each
                  underwriter, if any, stating that such accountants are
                  independent public accountants within the meaning of the
                  Securities Act and the applicable rules and regulations
                  adopted by the SEC thereunder, and otherwise in customary form
                  and covering such financial and accounting matters as are
                  customarily covered by letters of the independent certified
                  public accountants delivered in connection with primary or
                  secondary underwritten public offerings, as the case may be;

                           (xi) make generally available to its stockholders a
                  consolidated earnings statement (which need not be audited)
                  covering a period of 12 months beginning after the effective
                  date of a Registration Statement as soon as reasonably
                  practicable after the end of such period, but no later than 15
                  months after the effective date of the Registration Statement,
                  which earnings statement shall satisfy the requirements of an
                  earnings statement under Section 11(a) of the Securities Act;
                  and

                           (xii) promptly notify each seller of Registrable
                  Common Stock and the underwriter or underwriters, if any:

                                    (1) when the Registration Statement, any
                                    pre-effective amendment, the Prospectus or
                                    any free writing prospectus or
                                    post-effective amendment to the Registration
                                    Statement has been filed and, with respect
                                    to the Registration Statement or any
                                    post-effective amendment, when the same has
                                    become effective;

                                    (2) of any written request by the SEC for
                                    amendments or supplements to the
                                    Registration Statement or Prospectus;

                                    (3) of the notification to the Company by
                                    the SEC of its initiation of any proceeding
                                    with respect to the issuance by the SEC of
                                    any stop order suspending the effectiveness
                                    of the Registration Statement; and

                                    (4) of the receipt by the Company of any
                                    notification with respect to the suspension
                                    of the qualification of any Registrable
                                    Common Stock for sale under the applicable
                                    securities or blue sky laws of any
                                    jurisdiction.

         (b) [Intentionally left blank.]

                                       11
<PAGE>

         (c) The Company shall make available to Holder's Counsel, each
preliminary Prospectus, free writing prospectus and Prospectus and each
amendment or supplement thereto, each letter written by or on behalf of the
Company to the SEC or the staff of the SEC (or other governmental agency or
self-regulatory body or other body having jurisdiction, including any domestic
or foreign securities exchange), and each item of correspondence from the SEC or
the staff of the SEC (or other governmental agency or self-regulatory body or
other body having jurisdiction, including any domestic or foreign securities
exchange), in each case relating to a Registration Statement (other than any
portion thereof which contains information for which the Company has sought
confidential treatment). The Company will promptly notify Holder's Counsel by
facsimile of the effectiveness of each Registration Statement or any
post-effective amendment. The Company will promptly respond to any and all
comments received from the SEC, with a view towards causing each Registration
Statement or any amendment thereto to be declared effective by the SEC as soon
as practicable and shall file an acceleration request as soon as practicable
following the resolution or clearance of all SEC comments or, if applicable,
following notification by the SEC that any such Registration Statement or any
amendment thereto will not be subject to review.

         (d) At all times after the Company has filed a registration statement
with the SEC pursuant to the requirements of either the Securities Act or the
Exchange Act, the Company shall file all reports required to be filed by it
under the Securities Act and the Exchange Act and the rules and regulations
adopted by the SEC thereunder, and take such further action as any Holders may
reasonably request, all to the extent required to enable such Holders to be
eligible to sell Registrable Common Stock pursuant to Rule 144 under the
Securities Act (or any similar rule then in effect).

         (e) The Company may require each seller of Registrable Common Stock as
to which any registration is being effected to furnish and such seller shall
furnish, to the Company any other information regarding such seller and the
distribution of such securities as the Company may from time to time reasonably
request in writing.

         (f) Each seller of Registrable Common Stock agrees by having its stock
treated as Registrable Common Stock hereunder that, upon notice of the happening
of any event as a result of which the Prospectus included in such Registration
Statement contains an untrue statement of a material fact or omits any material
fact necessary to make the statements therein not misleading (a "Suspension
Notice"), such seller will forthwith discontinue disposition of Registrable
Common Stock for a reasonable length of time until such seller is advised in
writing by the Company that the use of the Prospectus may be resumed and is
furnished with a supplemented or amended Prospectus as contemplated by Section
6(c) hereof, and, if so directed by the Company, such seller will deliver to the
Company (at the Company's expense) all copies, other than permanent file copies
then in such seller's possession, of the Prospectus covering such Registrable
Common Stock current at the time of receipt of such notice; provided, however,
that such postponement of sales of Registrable Common Stock by the Holders shall
not exceed one hundred and twenty (120) days in the aggregate in any one year.
If the Company shall give any notice to suspend the disposition of Registrable
Common Stock pursuant to a Prospectus, the Company shall extend the period of
time during which the Company is required to maintain the Registration Statement
effective pursuant to this Agreement by the number of days during the period
from and including the date of the giving of such notice to and including the
date such seller either is advised by the Company that the use of the Prospectus
may be resumed or receives the copies of the supplemented or amended Prospectus
contemplated by Section 6(c). In any event, the Company shall not be entitled to
deliver more than three (3) Suspension Notices in any one year. Nothing in this
Section 6(f) shall be deemed to extend the 60 day limit to any postponement or
withdrawal period as described in Section 2(d) regarding restrictions on Demand
Registrations.

         7. Registration Expenses.

         (a) All reasonable, documented out of pocket expenses incident to the
Company's performance of or compliance with this Agreement, including, without
limitation, all registration and filing fees, fees and expenses of compliance
with securities or blue sky laws, listing application fees, printing expenses,
transfer agent's and registrar's fees, costs of distributing Prospectuses in
preliminary and final form as well as any supplements thereto, and fees and
disbursements of counsel for the Company and all independent certified public
accountants and other Persons retained by the Company (all such expenses being
herein called "Registration Expenses") (but not including any underwriting
discounts or commissions attributable to the sale of Registrable Common Stock or
legal fees and expenses of the Holders, which shall be borne by the Holders),
shall be borne 50% by the Company, on the one hand, and 50% by the Holders on
the other, subject to the provisions of Section 7(b) hereof. In addition, the
Company shall pay its internal expenses (including, without limitation, all
salaries and expenses of its officers and employees performing legal or
accounting duties), the expense of any annual audit or quarterly review, the
expense of any liability insurance and the expenses and fees for listing the
securities to be registered on each securities exchange on which they are to be
listed.

         (b) In connection with each registration initiated hereunder, if
another holder of the Company's Common Stock exercises piggyback rights with
respect to or is otherwise included in such registration, then, in such event,
the portion of the Company's reasonable out of pocket documented expenses to be
borne by the Holder shall be the lesser of (i) 50%, and (ii) the Holders' pro
rata portion, of such expenses (based on the Holders' proportionate number of
shares included in such registration statement). For the avoidance of doubt, the
reasonable, documented out of pocket expenses of the Company shall not include
(i) any amounts for which the Company received reimbursement from other selling
stockholders or (ii) any amounts payable by the Company for counsel fees or
other similar fees, commissions and expenses incurred by other selling
stockholders. If the Holders exercise piggyback rights with respect to an
offering by the Company, the Company shall bear all reasonable, documented out
of pocket expenses of any such piggyback registrations other than (i) the
Holders' pro rata portion of such expenses (based on the Holders' proportionate
number of shares included in such registration statement) and (ii) fees and
expenses of Holders' Counsel and underwriter discounts; provided, however, that
in no event shall the expenses to be borne by the Holders exceed 50% of the
Company's reasonable, documented out of pocket expenses. For purposes of the
proviso set forth in the preceding sentence, the reasonable, documented out of
pocket expenses of the Company shall not include (i) any amounts for which the
Company received reimbursement from other selling stockholders or (ii) any
amounts payable by the Company for counsel fees or other similar fees,
commissions and expenses incurred by other selling stockholders

         (c) The obligations set forth in Section 7(a) and Section 7(b) hereof
shall apply irrespective of whether a registration, once properly demanded, if
applicable, becomes effective, is withdrawn or suspended, is converted to
another form of registration and irrespective of when any of the foregoing shall
occur.

                                       13

         8. Indemnification.

         (a) The Company shall indemnify, to the fullest extent permitted by
law, each Holder, its officers, directors and Affiliates and each Person who
controls such Holder (within the meaning of Section 15 of the Securities Act)
against all losses, claims, damages, liabilities and reasonable expenses arising
out of or based upon any untrue or alleged untrue statement of material fact
contained in any Registration Statement, free writing prospectus, Prospectus or
preliminary Prospectus or any amendment thereof or supplement thereto or any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading or any violation or
alleged violation by the Company of the Securities Act, the Exchange Act or
applicable "blue sky" laws, except insofar as the same are made in reliance and
in conformity with information relating to such Holder furnished in writing to
the Company by such Holder expressly for use therein or caused by such Holder's
failure to deliver to such Holder's immediate purchaser a copy of the
Registration Statement, free writing prospectus or Prospectus or any amendments
or supplements thereto (if the same was required by applicable law to be so
delivered) after the Company has furnished such Holder with a sufficient number
of copies of the same. In connection with an underwritten offering, the Company
shall indemnify such underwriters, their officers and directors and each Person
who controls such underwriters (within the meaning of the Securities Act) to the
same extent as provided above with respect to the indemnification of the
Holders.

         (b) In connection with any Registration Statement in which a Holder of
Registrable Common Stock is participating, each such Holder shall furnish to the
Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such Registration Statement, free
writing prospectus or Prospectus and, shall indemnify, to the fullest extent
permitted by law, the Company, its officers, directors and Affiliates, and each
Person who controls the Company (within the meaning of Section 15 of the
Securities Act) against all losses, claims, damages, liabilities and reasonable
expenses arising out of or based upon any untrue or alleged untrue statement of
material fact contained in the Registration Statement, free writing prospectus,
Prospectus or preliminary Prospectus or any amendment thereof or supplement
thereto or any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein not misleading, but
only to the extent that the same are made in reliance and in conformity with
information relating to such Holder furnished in writing to the Company by such
Holder expressly for use therein or caused by such Holder's failure to deliver
to such Holder's immediate purchaser a copy of the Registration Statement, free
writing prospectus or Prospectus or any amendments or supplements thereto (if
the same was required by applicable law to be so delivered) after the Company
has furnished such Holder with a sufficient number of copies of the same;
provided, however, that the obligation to indemnify shall be several, not joint
and several, among such Holders and the liability of each such Holder shall be
in proportion to and limited to the net amount received by such Holder from the
sale of Registrable Common Stock pursuant to such Registration Statement.

                                       14
<PAGE>

         (c) Any Person entitled to indemnification hereunder shall (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification and (ii) permit such indemnifying party to assume
the defense of such claim with counsel reasonably satisfactory to the
indemnified party. If such defense is assumed, the indemnifying party shall not
be subject to any liability for any settlement made by the indemnified party
without its consent (but such consent will not be unreasonably withheld). The
indemnified party shall have the right to employ separate counsel in any such
action and participate in the defense thereof, but the fees and expenses of such
counsel shall be paid by the indemnified party unless (i) the indemnifying party
fails to assume the defense of such action or (ii) the named parties to any such
action include both the indemnifying party and the indemnified party and such
parties have been advised by counsel to the indemnifying party that either (x)
representation of such indemnified party and the indemnifying party by the same
counsel would be inappropriate under applicable standards of professional
conduct or (y) there may be one or more legal or equitable defenses available to
the indemnified party which are different from, in conflict with or additional
to those available to the indemnifying party. In either such case, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the indemnified parties, it being understood, however, that the
indemnifying party shall not be liable for the fees and expenses of more than
one separate firm or attorneys (in additional to any local counsel) for all
indemnified parties. Failure to give prompt written notice shall not release the
indemnifying party from its obligations hereunder.

         (d) The indemnification provided for under this Agreement shall remain
in full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director or controlling Person of such
indemnified party and shall survive the transfer of securities.

         (e) If the indemnification provided for in or pursuant to this Section
8 is due in accordance with the terms hereof, but is held by a court to be
unavailable or unenforceable in respect of any losses, claims, damages,
liabilities or expenses referred to herein, then each applicable indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages, liabilities or expenses in such proportion as is appropriate to
reflect the relative fault of the indemnifying party on the one hand and of the
indemnified party on the other in connection with the statements or omissions
which result in such losses, claims, damages, liabilities or expenses as well as
any other relevant equitable considerations. The relative fault of the
indemnifying party on the one hand and of the indemnified Person on the other
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the indemnifying
party or by the indemnified party, and by such party's relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. In no event shall the liability of any selling Holder be
greater in amount than the amount of net proceeds received by such Holder upon
such sale or the amount for which such indemnifying party would have been
obligated to pay by way of indemnification if the indemnification provided for
under Section 8(a) or 8(b) hereof had been available under the circumstances.

         9. Participation in Underwritten Registrations.

         No Person may participate in any registration hereunder which is
underwritten unless such Person (a) agrees to sell such Person's securities on
the basis provided in any underwriting arrangements approved by the Person or
Persons entitled hereunder to approve such arrangements and (b) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents required under the terms of such underwriting
arrangements.

         10.      Rule 144.

         The Company covenants that it will file the reports required to be
filed by it under the Securities Act and the Exchange Act and the rules and
regulations adopted by the SEC thereunder, and it will take such further action
as any Holder may reasonably request to make available adequate current public
information with respect to the Company meeting the current public information
requirements of Rule 144(c) under the Securities Act, to the extent required to
enable such Holder to sell Registrable Common Stock without registration under
the Securities Act within the limitation of the exemptions provided by (i) Rule
144 under the Securities Act, as such Rule may be amended from time to time, or
(ii) any similar rule or regulation hereafter adopted by the SEC. Upon the
request of any Holder, the Company will deliver to such Holder a written
statement as to whether it has complied with such information and requirements.

         11.      Miscellaneous.

         (a) Notices. All notices, requests, consents and other communications
required or permitted hereunder shall be in writing and shall be hand delivered

transmission (with immediate telephone confirmation thereafter),

         the Company may Transfer, subject to the provisions of Section 3
         hereof, such excess Offered Shares on the terms, conditions and

         exercising rights pursuant to this Section 2(a)) to any Third Party

         the case maybe, shall modify the terms of the proposed Transfer of
         Offered Shares in any way, the Company shall send an amended First
         Offer to each of the Stockholders. Each Stockholder shall, if it so
         desires to exercise its right of First Offer, as so amended, prior to
         the later of five (5) days after the date such amended First Offer is
         received by such Stockholder or the end of the original Acceptance
         Period, deliver to the Offeror an amended notice of acceptance
         specifying the amended Accepted Number and/or such other amended term
         of acceptance pursuant to this Section 2(a).

         5% or more of the Company's then outstanding Common Stock on a fully
         diluted basis ("Stockholder Offered Shares") to any bona fide Third
         Party, the Stockholder Offeror shall, before such Transfer, deliver to
         the other Stockholders an offer (the "Stockholder First Offer") to
         Transfer to such Stockholders a pro rata percentage of the Stockholder

         2(b); provided, however, that this Section 2(b) shall not apply in

         (provided that the purchaser of the shares sold by the Investor in any
         such non-underwritten offering shall not, as a result of such purchase
         from the Investor, hold more than 5% of the Common Stock of the
         Company), (B) any transfers by the Investor to a wholly-owned
         subsidiary, (C) any distribution to the stockholders of the Investor,
         (D) in the case of a Founder which is a corporation (v) any transfer to
         a wholly-owned subsidiary, or (w) any distribution to the stockholders
         of such corporation, (E) in the case of a Founder (or any distributee
         of shares from a Founder permitted by clause (D)(w), above), any
         transfer to (x) a spouse, sibling or lineal ancestor or descendant or
         any adopted children, (y) a trust or trusts of which a Founder (or
         permitted distributees) are the primary beneficiaries or charitable
         remainder trusts in which any such stockholder (or permitted
         distributee) has an interest, or (z) a partnership or limited liability

                                       5

         company in which any such Founder (or permitted distributees) are the
         only partners or members, as the case may be; provided, however that
         any such transferee or other recipient receiving shares of Common Stock
         pursuant to a transfer governed by subsections (B), (C), (D) or (E) of
         this Section 2(b) will agree to become bound by the same restrictions
         on transfer and right of first refusal provisions and in the same
         manner as the Investor and the Founders, as applicable. The Stockholder
         First Offer shall state that the Stockholder Offeror proposes to
         Transfer the Stockholder Offered Shares and specify the number of
         Stockholder Offered Shares and the terms (including the purchase price)
         of the proposed Transfer. The Stockholder First Offer shall remain open
         and irrevocable for a period of fifteen (15) days (the "Stockholder
         Acceptance Period") from the date of its receipt by the other
         Stockholders.

                           (ii) The other Stockholders may accept the
         Stockholder First Offer by delivering to the Stockholder Offeror
         written notice within the Stockholder Acceptance Period, which notice
         shall state the number of Stockholder Offered Shares such other
         Stockholder desires to purchase (the "Stockholder Accepted Number").

                           (iii) The Transfer of Stockholder Offered Shares to
         the other Stockholders to the extent the other Stockholders have
         exercised their rights under this Section 2(b), shall be made on a
         Business Day, as designated by the Stockholder Offeror, not less than
         ten (10) nor more than thirty (30) days after expiration of the
         Stockholder Acceptance Period on the terms and conditions specified in
         the Stockholder First Offer, which terms and conditions shall be
         identical to the terms of the proposed Transfer to the Third Party.

                           (iv) If the number of Stockholder Offered Shares
         exceeds the aggregate Stockholder Accepted Number of Stockholder
         Offered Shares with respect to which the other Stockholders exercised
         their rights under this Section 2(b), the Stockholder First Offer shall
         be deemed to be withdrawn with respect to such excess and the
         Stockholder Offeror may Transfer, subject to the provisions of Section
         3 hereof, such excess Stockholder Offered Shares on the terms,
         conditions and purchase price specified in the Stockholder First Offer
         (which shall be the same terms, conditions and purchase price available
         to the other Stockholders exercising rights pursuant to this Section
         2(b)) to any Third Party within ninety (90) days after expiration of
         the Stockholder Acceptance Period. If such Transfer is not made within
         such 90 day period, the restrictions provided for in this Section 2(b)
         shall again become effective.

                           (v) In the event a Stockholder Offeror or such Third
         Party, as the case maybe, shall modify the terms of the proposed
         Transfer of Stockholder Offered Shares in any way, the Stockholder
         Offeror shall send an amended Stockholder First Offer to the other
         Stockholders. The other Stockholders shall, if they so desire to
         exercise their right of Stockholder First Offer, as so amended, prior
         to the later of five (5) days after the date such amended Stockholder
         First Offer is received by such other Stockholders or the end of the
         original Stockholder Acceptance Period, deliver to the Stockholder
         Offeror an amended notice of acceptance specifying the amended
         Stockholder Accepted Number and/or such other amended term of
         acceptance pursuant to this Section 2(b).

                  (c) Transfer Leading to Change of Control. In the event that
any of the Company or the Founders has received a bona fide offer (an "Offer")
by an independent Third Party to purchase shares of capital stock of the Company
(including shares with preferential voting rights and shares issuable upon
conversion or exercise of options and warrants or other convertible securities
of the Company) that would reasonably likely lead to a Change of Control, before
accepting such Offer (i) the Company or the Founder, as the case may be, shall,
within three (3) days of receipt of such Offer, provide written notice to the
Investor of the identity of the independent Third Party and the material terms
and conditions of the Offer, and (B) afford the Investor a period of ten (10)
days in which to submit its own proposal for a Change of Control transaction. In
the event that the Company or the Founder, as the case may be, does not receive
a proposal for a Change of Control transaction from the Investor within such 10
day period, the Company or the Founder, as the case may be, shall be free to
accept the Offer upon terms no less favorable than those set forth in the
original Offer. In the event that the Company does receive a proposal for a
Change of Control transaction from the Investor, the Board of Directors of the
Company, in the good faith exercise of its business judgment, may determine to
accept neither offer, to accept the offer which the Board of Directors finds to
be more favorable to the Company or to solicit additional offers from the
independent Third Party, the Company and others. In the event of any
inconsistency between the provisions of Section 2(a) and this Section 2(c) with
respect to an Offer likely to lead to a Change of Control, the provisions of
this Section 2(c) shall control.

                  (d) The right of first refusal set forth in Sections 2(a) and
2(b) above shall not apply with respect to Excluded Stock.

                  Section 3. Standstill. The Investor will not purchase any
additional shares of the Company's Common Stock until the one year anniversary
of the date hereof, provided, however, that, notwithstanding the foregoing, the
foregoing shall not restrict, limit, prohibit or prevent (i) the Investor
Director from taking any action or omitting to take any action in his capacity
as a director of the Company, (ii) the Investor from voting its securities at
any meeting of the stockholders or by written consent in lieu thereof in any
manner determined by the Investor, (iii) any representative of the Investor who
serves as a director, officer or Affiliate of any other company (other than a
subsidiary of the Investor) from taking any action or omitting to take any
action in his capacity as a director, officer or Affiliate of such company, (iv)
the Investor from exercising its rights of first refusal (as described in
Section 2), (v) the Investor from exercising the Warrant, or (vi) the Investor
from investing in any entity that, prior to contemplation of any such
investment, owns or holds shares of the Company's Common Stock.

                  Section 4.        Corporate Governance.

                  (a) As of the date hereof and for so long as the Investor owns
or holds at least 5,379,443 shares of Common Stock, the Investor will be
entitled to designate one (1) person (reasonably acceptable to the Company) that
the Company is required to nominate as a member of the Company's board of
directors (the "Investor Director"), who shall initially be Benjamin Chesir, and
each of the Founders shall be required to vote shares they own or hold in
approval of such nomination. For so long as the Investor owns or holds at least
5,379,443 shares of Common Stock, the Investor shall be required to vote its
shares in favor of each individual nominated as a member of the Company's board
of directors by the board of directors, by the nominating committee of the
Company or such other ad hoc committee as may be acting in such nominating role.
As of the date hereof the Company agrees to increase the number of members of
the Company's board of directors by one and to fill such additional position
with the Investor Director. Subject to applicable law and the rules governing
the over the counter bulletin board market or any national securities exchange
on which equity securities of the Company may be listed hereafter, as
applicable, as of the date hereof and for so long as the Investor owns or holds
at least 5,379,443 shares of Common Stock, the Investor Director shall have the
right to be designated to serve on each committee of the board of directors
(other than the audit committee, which shall be comprised solely of independent
directors).

                  (b) The Founders agree that in the event of any vacancy on the
Board of Directors, whether caused by the death, disability, retirement,
resignation, removal, termination of term of office or otherwise, with respect
to any Investor Director, the Founders will use their commercially reasonable
efforts to call, or to cause the appropriate officers of the Company to call, a
special or general meeting of stockholders and to vote, and to cause their
Affiliates to vote, all shares of Voting Stock beneficially owned or held of
record by them and their Affiliates for, or to take and to cause their
Affiliates to take all actions by written consent in respect of all such shares
of Voting Stock in lieu of any such meeting, and shall take all reasonable
actions within their control that are necessary to cause, the election to the
Board of Directors of another individual designated by the Investor to fill such
vacancy; provided that the foregoing shall not apply in the event that the Board
of Directors takes such action to so constitute the Board of Directors without
stockholder action.

                  (c) The Investor may at any time request that a person
nominated by it in accordance with this Section 4 be removed as a member of the
Board of Directors, with or without cause, and upon the written request of the
Investor to the Founders, the Founders agree to vote, and to cause their
respective Affiliates to vote, all of their Voting Stock to effect such removal.

                  (d) The Company agrees to cooperate with the Investor, and to
take all such actions that it may lawfully take, to achieve the results intended
by this Section 4.

                  (e) Notwithstanding anything to the contrary contained in this
Agreement, for so long as the Investor owns or holds 5,379,443 shares of Common
Stock, no transfer of shares of Voting Stock by the Investor or by the Founders
(or any of their respective Affiliates), other than transfers of less than 5% of
the Company's then outstanding shares of Common Stock on a fully diluted basis
permitted under Section 2(b)(i), shall be effective and the Company agrees that
no such purported transfer shall be recognized by it or registered on its books
and records, unless the transferee agrees in writing to be bound by the
obligations of the Investor or the Founders, as applicable, set forth in this
Section 4.

                  Section 5. Protective Provisions. For so long as the Investor
owns or holds at least 5,379,443 shares of Common Stock, consent of the Investor
Director, which consent, will not be unreasonably withheld, is required for:

                                       8

amount of, or the issuance or authorization of any obligation or security
convertible into or evidencing a right to purchase, or the reclassification of
any of the Company's authorized stock into any stock of any class, or any
obligation or security convertible into or evidencing a right to purchase, any
stock of any class ranking senior to the Common Stock of the Company purchased
by the Investor as to voting or dividends or upon the distribution of assets
upon the Company's dissolution, liquidation or the winding up of its affairs
with an aggregate (since the date hereof) liquidation preference, either in one
or a series of related transactions, of greater than $10.0 million;

                  (b) Acquiring any business or assets (including through the
entry into any joint venture or strategic alliance) involving aggregate
consideration or commitments having a value (taking into account the value of
any non-cash consideration paid or committed to) in excess of $30.0 million,
individually or in the aggregate from the date hereof, or making any sales or
other dispositions of businesses or assets (including issuance or sales of
capital stock of subsidiaries to third parties) having a value (taking into
account the value of any non-cash consideration paid or committed to) in excess
of $10.0 million, individually or in the aggregate, in each case during any 18
month period;

                  (c)      Any related party transaction or series of related
party transactions in excess of $5.0 million;

                  (d) Any (x) dividend or distribution (whether made in cash,
securities or other property) declared or paid on or with respect to, or any
repurchase or optional redemption of, any shares of capital stock of the Company
or (y) issuance of debt (including convertible or exchangeable debt), which, in
the case of each of (x) and (y), exceed $10.0 million in the aggregate (since
the date hereof); and

                  (e) The Company or any subsidiary to engage in any business
other than any business which is the same, similar, ancillary or related to any
of the businesses that the Company and its subsidiaries were engaged in on
January 22, 2007.

Investor owns at least 5,379,443 shares of Common Stock:

                           (i) So long as the Company is subject to the
         reporting requirements of Section 13 or 15(d) of the Exchange Act, the
         Company will use its reasonable best efforts to file with the SEC, at
         the times specified for the filing of such information, and shall
         simultaneously furnish the Investor with copies of, such annual and
         quarterly reports as are specified in Sections 13 or 15(d) of the
         Exchange Act and applicable to a U.S. person subject to such sections.
         If the Company has not filed such annual or quarterly reports with the
         SEC within fifteen (15) calendar days of the times specified for the
         filing of such information, the Company shall be required to,
         immediately thereafter, provide the Investor with the financial
         information set forth in Section 6(a)(ii) below.

                                       9
<PAGE>

                           (ii) At any time that the Company is not subject to
         the reporting requirements of Section 13 or 15(d) of the Exchange Act,
         the Company shall furnish to the Investor (x) quarterly unaudited
         summary consolidated financial information within 45 days after the end
         of each quarter, and (y) annual consolidated audited financial
         statements within 75 days after each year end, which, in the case of
         (x) and (y) above, shall be prepared in accordance with U.S. generally
         accepted accounting principles applied on a consistent basis.
                           (iii) If the Investor is required to consolidate the
         Company into the Investor's financial statements, the Company shall
         furnish such additional information as may be reasonably requested by
         the Investor and necessary for such consolidation.

                           (iv) The Investor and, to the extent applicable, its
         regulators will have reasonable access to information and the Company's
         management and other employees.

                           (v) The Investor and its external and internal
         auditors will have the right to audit or examine the Company's books
         and records and its policies and procedures, within reasonable bounds
         of frequency and amount of time required from the Company.

                           (vi) The Company will provide such other assistance
         and cooperation as is reasonably requested by the Investor and its
         auditors and regulators.

                           (vii) Confidentiality. For so long as the Company is
         subject to the reporting requirements of Section 13 or 15(d) of the
         Exchange Act, the Investor, its employees and agents shall remain
         subject to the confidentiality provisions set forth in the
         Non-Disclosure Agreement by and between the New York Mercantile
         Exchange, Inc. and the Company dated December 5, 2006, other than to
         the extent information furnished pursuant to Section 6(a)(iii) is
         consolidated in the Investor's financial statements as provided
         therein.

                  (b) Rule 144. For so long as the Investor owns or holds any of
its initial investment of 10,758,886 shares of Common Stock or shares issued
upon exercise of the Warrant, the Company covenants that it will file the
reports required to be filed by it under the Securities Act and the Exchange Act
and the rules and regulations adopted by the SEC thereunder, and it will take
such further action as the Investor may reasonably request to make available
adequate current public information with respect to the Company meeting the
current public information requirements of Rule 144(c) under the Securities Act,
to the extent required to enable the Investor to sell the Company's Common Stock
without registration under the Securities Act within the limitation of the
exemptions provided by (i) Rule 144 under the Securities Act, as such Rule may
be amended from time to time, or (ii) any similar rule or regulation hereafter

                  (c) Expenses. The Investor shall bear all of the reasonable,
documented out of pocket costs and expenses associated with the information,
examination and audit provisions set forth in this Section 6 other than as
provided in Sections 6(a)(i) and Section 6(a)(ii) hereof and Section 6(c) and
shall promptly reimburse the Company for any documented expenses incurred by the
Company in connection therewith, provided, however, that in the event the
Company is otherwise required to have its financial information audited in its
capacity as a public company, the Investor shall not be responsible to bear any
costs or expenses in connection therewith. Notwithstanding the foregoing, the
Investor shall bear all of the reasonable, documented, out of pocket costs and
expenses relating to services not normally associated with the Company's
examination and audit process, but which are incurred in connection therewith in
response to a request for additional information by the Investor pursuant to
this Section 6.

affecting any other provision or parties to this Agreement, this Agreement shall
terminate and the rights and obligations of the parties hereto shall have no
force or effect at such time as the Investor ceases to own or hold any shares of
Common Stock issued pursuant to the Stock and Warrant Purchase Agreement,
including shares issued or issuable upon exercise of the Warrant. For the
purposes of the immediately preceding sentence, all shares issuable upon
exercise of the Warrant shall be deemed to be held by the Investor not
withstanding the fact that the Warrant has not yet been executed as it relates
to such shares.

                  Section 8. Amendments. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, except by a written instrument executed by the Stockholders and
the Company. This Agreement cannot be changed, modified, discharged or
terminated by oral agreement.

                  Section 9. No Inconsistent Agreement. Neither the Company nor
any Stockholder shall enter into any agreement with respect to the Common Stock
beneficially owned or held of record by it which is inconsistent with the rights
granted to the Investor or the Founders in this Agreement or otherwise conflicts
with the provisions hereof.

                  Section 10. Notices. All notices, requests, consents and other
communications required or permitted hereunder shall be in writing and shall be

this Agreement, the construction of its terms and the interpretation of the

hereby is not affected in any manner materially adverse to any party. Upon such

Agreement so as to effect the original intent of the parties as closely as

law, including recovery of damages, will be entitled to specific performance of
its rights under this Agreement without proof of actual damages and without the
requirement of posting bond or other security. Each party hereto hereby 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 Agreement and hereby
agrees to waive the defense in any action for specific performance that a remedy
at law would be adequate.

                  Section 18. Jurisdiction. Any suit, action or proceeding
seeking to enforce any provision of, or based on any matter arising out of or in
connection with, this Agreement or the transactions contemplated hereby may be
brought in any federal or state court located in the County and State of New
York, and each of the parties hereby consents to the jurisdiction of such courts
(and of the appropriate appellate courts therefrom) in any such suit, action or
proceeding and irrevocably waives, to the fullest extent permitted by law, any
objection which it may now or hereafter have to the laying of the venue of any
such suit, action or proceeding in any such court or that any such suit, action
or proceeding which is brought in any such court has been brought in an
inconvenient forum. Process in any such suit, action or proceeding may be served
on any party anywhere in the world, whether within or without the jurisdiction
of any such court. Without limiting the foregoing, each party agrees that
service of process on such party as provided in Section 10 shall be deemed
effective service of process on such party.

1.       DEFINITIONS

         As used in this Warrant, the following terms have the respective
meanings set forth below:

         "Affiliate" of any Person means any other Person which directly, or
indirectly through one or more intermediaries, controls, or is controlled by, or
is under common control with, such Person. The term "control" (including the
terms "controlling," "controlled by" and "under common control with") as used
with respect to any Person means the possession, direct or indirect, of the
power to direct or cause the direction of the management and policies of such
Person, whether through the ownership of voting securities, by contract or
otherwise. Notwithstanding anything to the contrary herein, none of (i) the
Holder (and its Affiliates) nor (ii) any of the individual Founders (and their
Affiliates) shall be deemed to be an Affiliate of any other.

         "Appraisal Procedure" means the following procedure to determine the
fair market value, as to any security, for purposes of the definition of "Fair
Market Value" or the fair market value, as to any other property (in either
case, the "Valuation Amount"). The Valuation Amount shall be determined in good
faith jointly by the Board of Directors and NYMEX, as representative of the
Holders; provided, however, that if such parties are not able to agree on the
Valuation Amount within a reasonable period of time (not to exceed twenty (20)
Business Days), the Valuation Amount shall be determined by an investment
banking firm of national reputation, which firm shall be reasonably acceptable
to the Board of Directors and NYMEX. If the Board of Directors and NYMEX are
unable to agree upon an acceptable investment banking firm within ten (10) days
after the date either party proposed that one be selected, the investment
banking firm will be selected by an arbitrator located in New York City, New
York, selected by the American Arbitration Association (or if such organization
ceases to exist, the arbitrator shall be chosen by a court of competent
jurisdiction). The arbitrator shall select the investment banking firm (within
ten (10) days of his appointment) from a list, jointly prepared by the Board of
Directors and NYMEX, of not more than six investment banking firms of national
reputation in the United States, of which no more than three may be named by the
Board of Directors and no more than three may be named by NYMEX. The arbitrator
may consider, within the ten day period allotted, arguments from the parties
regarding which investment banking firm to choose, but the selection by the
arbitrator shall be made in its sole discretion from the list of six. The Board
of Directors and NYMEX shall submit their respective valuations and other
relevant data to the investment banking firm, and the investment banking firm
shall, within thirty days of its appointment, make its own determination of the
Valuation Amount. The determination of the final Valuation Amount by such
investment banking firm shall be final and binding upon the parties. The Company
and NYMEX shall each bear 50% of the fees and expenses of the investment banking
firm and arbitrator (if any) used to determine the Valuation Amount. If required
by any such investment banking firm or arbitrator, the Company shall execute a
retainer and engagement letter containing reasonable terms and conditions,
including, without limitation, customary provisions concerning the rights of
indemnification and contribution by the Company in favor of such investment
banking firm or arbitrator and its officers, directors, partners, employees,
agents and Affiliates.

purposes, as of the Exercise Date.

                  (c) Payment of the Warrant Price shall be made at the option
of the exercising Holder in cash or by delivery of a certified or official bank
check or bank cashier's check payable to the order of the Company, or by wire
transfer of immediately available funds, in the amount of such Warrant Price.
Payment shall be made to the Company at its Designated Office prior to the close
of business on the Exercise Date.

                  2.2 Payment of Taxes. All shares of Warrant Stock issuable
upon the exercise of this Warrant pursuant to the terms hereof shall be validly
issued, fully paid and nonassessable, issued without violation of any preemptive
or similar rights of any stockholder of the Company and free and clear of all
Liens. The Company shall pay all expenses (including stamp taxes) in connection
with the issue or delivery of the shares of Warrant Stock, unless such tax or
charge is imposed by law upon the Holder. In addition, the Company shall not be
required to pay any tax or governmental charge which may be issuable upon
exercise of this Warrant payable in respect of any Transfer involved in the
issue and delivery of shares of Warrant Stock in a name other than that of the
exercising Holder, and no such issue or delivery shall be made unless and until
the Person requesting such issue has paid to the Company the amount of any such
tax, or has established to the satisfaction of the Company that such tax has
been paid.

                  2.3 Fractional Shares. The Company shall not be required to
issue a fractional share of Warrant Stock upon exercise of any Warrant. In lieu
of any fraction of a share to which any Holder would otherwise be entitled, the
Company shall make a cash payment equal to the Fair Market Value of one share of
Common Stock on the Exercise Date multiplied by such fraction.

law, has no present intention of distributing this Warrant or the shares of
Warrant Stock issuable upon exercise hereof, has no present arrangement or
understanding with any persons regarding the distribution of this Warrant or the
shares of Warrant Stock issuable upon exercise hereof (it being understood that
this representation and warranty does not limit the Holder's right to sell the
shares of Warrant Stock issuable upon exercise hereof pursuant to an effective
registration statement or otherwise in compliance with applicable federal and
state law) in violation of the Securities Act or any applicable state securities
law and that such Holder will not offer, sell or otherwise dispose of this

circumstances that will not result in a violation of the Securities Act and in
accordance with this Section 3.

                  (b) All shares of Warrant Stock issued upon exercise of this
Warrant (unless registered under the Securities Act) shall be stamped or

         ACT OR (II) THE TRANSACTION IS EXEMPT FROM REGISTRATION UNDER THE ACT
         AND, IF THE CORPORATION REQUESTS, AN OPINION SATISFACTORY TO THE

                  (c) The Holder understands that this Warrant and the shares of
Warrant Stock issuable on exercise hereof are "restricted securities" and have
not been, and will not be upon issuance, as the case may be, registered under
the Securities Act or any applicable state securities law.

                  (d) The Holder, whether on his or her own or by reason of the
business and financial experience of its management, has such knowledge,
sophistication and experience in business and financial matters so as to be
capable of evaluating the merits and risks of the prospective investment in this
Warrant and the shares of Warrant Stock issuable upon exercise hereof, and has
so evaluated the merits and risks of such investment. The Holder is able to bear
the economic risk of an investment in this Warrant and the shares of Common
Stock issuable upon exercise hereof and, at the present time, is able to afford
a complete loss of such investment.

                  (e) The Holder is an "accredited investor" as that term is
defined in Regulation D promulgated under the Securities Act.

                  3.2 Transfer of this Warrant. This Warrant is non-transferable
other than to a wholly-owned subsidiary of NYMEX or other Affiliate of NYMEX
(which is not a natural person) and any attempted transfer or assignment other
than as set forth in this Section 3.2 shall be void. Upon compliance with the
provisions of this Section 3.2, each transfer of this Warrant and all rights
hereunder, in whole or in part, shall be registered on the books of the Company
to be maintained for such purpose, upon surrender of this Warrant at the
Designated Office and compliance with the terms hereof, together with a written
assignment of this Warrant in the form of Annex B hereto duly executed by the
Holder or its agent or attorney and funds sufficient to pay any transfer taxes
described in Section 2.2 in connection with the making of such transfer. Upon
such compliance, surrender and delivery 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 denominations specified in such instrument of
assignment, and shall issue to the assignor a new Warrant evidencing the portion
of this Warrant not so assigned and this Warrant shall promptly be cancelled.

                  3.3 Warrant Stock Certificates. Each new certificate
evidencing Warrant Stock shall bear the appropriate restrictive legend set forth
in Section 3.1 hereof, except that (a) any such certificate representing Warrant
Stock issued to a Holder other than NYMEX or one of its permitted assigns shall
not bear the third legend relating to the Investor Rights Agreement and (b) such
certificate shall not bear such restrictive legend if the Warrant Stock is part
of a registered offering pursuant to an effective registration statement filed
with the SEC, or if, in the opinion of counsel for the Company, such legend is
not required in order to establish or assist in compliance with any provisions
of the Securities Act or any applicable state securities laws.

                  3.4 Mutilation or Loss. Upon receipt by the Company from the
Holder of evidence reasonably satisfactory to it of the loss, theft, destruction
or mutilation of this Warrant and an indemnity reasonably satisfactory to it (it
being understood that the written indemnification agreement or if an affidavit
of loss of the Holder shall be a sufficient indemnity) and, in case of
mutilation, upon surrender and cancellation hereof, the Company will execute and
deliver in lieu hereof a new Warrant of like tenor to such Holder; provided,
however, that, in the case of mutilation, no indemnity shall be required if this
Warrant in identifiable form is surrendered to the Company for cancellation.
Upon the issuance of any new Warrant under this Section 3.4, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto.

                  3.5 Expenses. Except as provided in Section 3.4, the Company
shall prepare, issue and deliver at its own expense any new Warrant required to
be issued hereunder.

                  3.6 Maintenance of Books. The Company agrees to maintain, at
the Designated Office (as defined in Section 8 hereof), books for the
registration and transfer of the Warrants.

4.       ANTIDILUTION PROVISIONS

         The Exercise Price shall be subject to adjustment from time to time as
set forth in this Section 4.

                  4.1 Upon Issuance of Common Stock. If the Company shall, at
any time or from time to time after the Original Issue Date and on or before the
Expiration Date, issue any shares of capital stock, options to purchase or
rights to subscribe for capital stock, securities by their terms convertible
into or exchangeable for capital stock, or options to purchase or rights to
subscribe for such convertible or exchangeable securities without consideration
or for consideration per share less than the higher of (x) $2.69 (the "Per Share
Purchase Price") and (y) the Fair Market Value per share of the Common Stock at
the time of such issuance, then the Exercise Price shall forthwith be lowered to
a price equal to the price obtained by multiplying:

                           (i) the Exercise Price in effect immediately prior to
         the issuance of such Common Stock, options, rights or securities by

                           (ii) a fraction of which (x) the numerator shall be
         the sum of (A) the number of shares of Common Stock Outstanding on a
         fully diluted basis immediately prior to such issuance and (B) the
         number of additional shares of Common Stock which the aggregate
         consideration for the number of shares of Common Stock so offered would
         purchase at the greater of the Per Share Purchase Price or the Fair
         Market Value per share of Common Stock immediately prior to such
         issuance and (y) the denominator shall be the number of shares of
         Common Stock Outstanding on a fully diluted basis immediately after
         such issuance.

                                       9
<PAGE>

The provisions of this Section 4.1 shall not apply to any issuance of Excluded
Stock and no adjustment shall be required pursuant to this Section 4.1 with
respect thereto.

                  4.2 Provisions Applicable to Adjustments. For the purposes of
any adjustment of the Exercise Price pursuant to Section 4.1, the following
provisions shall be applicable:

                           (i) In the case of the issuance of capital stock for
         cash in a public offering or private placement, the consideration shall
         be deemed to be the amount of cash paid therefor before deducting
         therefrom any discounts, commissions or placement fees payable by the
         Company to any underwriter or placement agent in connection with the
         issuance and sale thereof.

                           (ii) In the case of the issuance of capital stock for
         a consideration in whole or in part other than cash, the consideration
         other than cash shall be deemed to be the Fair Market Value thereof.

                           (iii) In the case of the issuance of options to
         purchase or rights to subscribe for capital stock, securities by their
         terms convertible into or exchangeable for capital stock, or options to
         purchase or rights to subscribe for such convertible or exchangeable
         securities (except for options to acquire Excluded Stock (as defined in
         Section 4.11 hereof)):

 (A)     the aggregate maximum number of shares of capital stock
         deliverable upon exercise of any such options to purchase or
         rights to subscribe for capital stock shall be deemed to have
         been issued at the time such options or rights were issued and
         for a consideration equal to the consideration (determined in the
         manner provided in subparagraphs (i) and (ii) of this Section
         4.2), if any, received by the Company upon the issuance of such
         options or rights plus the minimum purchase price provided in
         such options or rights for the capital stock covered thereby;

 (B)     the aggregate maximum number of shares of capital stock
         deliverable upon conversion of or in exchange for any such
         convertible or exchangeable securities or upon the exercise of
         options to purchase or rights to subscribe for such convertible
         or exchangeable securities and subsequent conversion or exchange
         thereof shall be deemed to have been issued at the time such
         securities, options, or rights were issued and for a
         consideration equal to the consideration received by the Company
         for any such securities and related options or rights (excluding
         any cash received on account of accrued interest or accrued
         dividends), plus the additional consideration, if any, to be
         received by the Company upon the conversion or exchange of such
         securities or the exercise of any related options or rights (the
         consideration in each case to be determined in the manner
         provided in paragraphs (i) and (ii) of this Section 4.2);

                                       10
<PAGE>

 (C)     on any change in the number of shares or exercise price of
         capital stock deliverable upon exercise of any such options or
         rights or conversions of or exchanges for such securities, other
         than a change resulting from the anti dilution provisions
         thereof, the Exercise Price shall forthwith be readjusted to such
         Exercise Price as would have been obtained had the adjustment
         made upon the issuance of such options, rights or securities not
         converted prior to such change or options or rights related to
         such securities not converted prior to such change been made upon
         the basis of such change;

 (D)     upon the expiration of any options to purchase or rights to
         subscribe for capital stock which shall not have been exercised,
         the Exercise Price computed upon the original issue thereof (or
         upon the occurrence of a record date with respect thereto), and
         any subsequent adjustments based thereon, shall, upon such
         expiration, be recomputed as if the only additional shares of
         capital stock issued were the shares of capital stock, if any,
         actually issued upon the exercise of such options to purchase or
         rights to subscribe for capital stock, and the consideration
         received therefor was the consideration actually received by the
         Company for the issue of the options to purchase or rights to
         subscribe for capital stock that were exercised, plus the
         consideration actually received by the Company upon such
         exercise; and

 (E)     no further adjustment of the
         Exercise Price adjusted upon the
         issuance of any such options,
         rights, convertible securities or
         exchangeable securities shall be
         made as a result of the actual
         issuance of capital stock on the
         exercise of any such rights or
         options or any conversion or
         exchange of any such securities.

                  4.3      Upon Stock Dividends, Subdivisions or Splits.

                  (a) If, at any time after the Original Issue Date and on or
before the Expiration Date, the number of shares of Common Stock Outstanding is
increased by a stock dividend payable in shares of Common Stock or by a
subdivision or split up of shares of Common Stock, then, following the record
date for the determination of holders of Common Stock entitled to receive such
stock dividend, or to be affected by such subdivision or split up, the Exercise
Price shall be appropriately decreased by multiplying the Exercise Price by a
fraction, the numerator of which is the number of shares of Common Stock
Outstanding immediately prior to such increase and the denominator of which is
the number of shares of Common Stock Outstanding immediately after such increase
in Outstanding shares.

                                       11
<PAGE>

                  (b) If, at any time after the Original Issue Date, the Company
shall declare or pay a dividend or make a distribution to all or substantially
all holders of Outstanding Common Stock, in either case, of evidences of
indebtedness, cash or other property or securities (excluding dividends referred
to in Section 4.3(a) above) or shall issue to all or substantially all holders
of Outstanding Common Stock rights or warrants to subscribe for or purchase any
of its securities (other than options to purchase or rights to subscribe for
Common Stock, securities by their terms convertible into or exchangeable for
Common Stock, or options to purchase or rights to subscribe for such convertible
or exchangeable securities in respect of which the Holder becomes entitled to
purchase Common Stock or securities by their terms convertible into or
exchangeable for Common Stock referred to in Section 4.1 above), then in each
such case the Exercise Price shall be forthwith lowered so that the same shall
equal the price determined by multiplying the Exercise Price in effect
immediately prior to the close of business on the date (the "Record Date") fixed
for the determination of holders of Common Stock entitled to receive such
dividend or distribution by a fraction, (i) the numerator of which shall be the
Fair Market Value of the Common Stock as of the Business Day next preceding the
Record Date less the Fair Market Value, as of the Record Date, of the portion of
the evidences of indebtedness, cash or other property or securities so
distributed, or of such rights or warrants, in each case, applicable to one
share of Common Stock, and (ii) the denominator of which shall be the Fair
Market Value of the Common Stock as of the Business Day next preceding the
Record Date, with such adjustment to become effective immediately prior to the
opening of business on the day following the Record Date. Notwithstanding the
foregoing, in the event that, with respect to any dividend or distribution to
which this Section 4.3(b) would otherwise apply, the numerator in the fraction
referred to in the first sentence of this Section 4.3(b) is zero (or is a
negative number), then the adjustment provided by this Section 4.3(b) shall not
be made and in lieu of such adjustment, the Company shall deliver to the Holder
on the date fixed for payment to stockholders of the Company of such divided or
distribution, the evidences of indebtedness, assets, other property or
securities, rights or warrants so distributed in respect of the number of shares
of Warrant Stock (determined as of the close of business on the Record Date)
issuable upon exercise hereof.

                  4.4 Upon Combinations or Reverse Stock Splits. If, at any time
after the Original Issue Date, the number of shares of Common Stock Outstanding
is decreased by a combination or reverse stock split of the Outstanding shares
of Common Stock into a smaller number of shares of Common Stock, then, following
the record date to determine shares affected by such combination or reverse
stock split, the Exercise Price shall be appropriately increased by multiplying
the Exercise Price by a fraction, the numerator of which is the number of shares
of Common Stock Outstanding immediately prior to such decrease and the
denominator of which is the number of shares of Common Stock Outstanding
immediately after such decrease in Outstanding shares.

                                       12
<PAGE>

                  4.5 Upon Reclassifications, Reorganizations, Consolidations or
Mergers. In the event of any capital reorganization of the Company, any
reclassification of the stock of the Company (other than a change in par value
or from par value to no par value or from no par value to par value or as a
result of a stock dividend or subdivision, split up or combination of shares),
or any consolidation or merger of the Company with or into another Person (where
the Company is not the surviving Person or where there is a change in or
distribution with respect to the Common Stock), each Warrant shall after such
reorganization, reclassification, consolidation, or merger be exercisable for
the kind and number of shares of stock or other securities or property of the
Company or of the successor Person resulting from such consolidation or
surviving such merger, if any, to which the holder of the number of shares of
Common Stock deliverable (immediately prior to the time of such reorganization,
reclassification, consolidation or merger) upon exercise of such Warrant would
have been entitled upon such reorganization, reclassification, consolidation or
merger. The provisions of this clause shall similarly apply to successive
reorganizations, reclassifications, consolidations, or mergers. The Company
shall not effect any such reorganization, reclassification, consolidation or
merger unless, prior to the consummation thereof, the successor Person (if other
than the Company) resulting from such reorganization, reclassification,
consolidation or merger, shall assume, by written instrument, the obligation to
deliver to the Holders such shares of stock, securities or assets, which, in
accordance with the foregoing provisions, such Holders shall be entitled to
receive upon such conversion.

                  4.6 Deferral in Certain Circumstances. In any case in which
the provisions of this Section 4 shall require that an adjustment shall become
effective immediately after a record date of an event, the Company may defer
until the occurrence of such event (a) issuing to the Holder with respect to any
Warrants exercised after such record date and before the occurrence of such
event the shares of capital stock issuable upon such exercise by reason of the
adjustment required by such event and issuing to such Holder only the shares of
capital stock issuable upon such exercise before giving effect to such
adjustments, and (b) paying to such Holder any amount in cash in lieu of a
fractional share of capital stock pursuant to Section 2.3 above; provided,
however, that the Company shall deliver to such Holder an appropriate instrument
or due bills evidencing such Holder's right to receive such additional shares or
such cash.

                  4.7 Appraisal Procedure. In any case in which the provisions
of this Section 4 shall necessitate that the Appraisal Procedure be utilized for
purposes of determining an adjustment to the Exercise Price, the Company may
defer until the completion of the Appraisal Procedure and the determination of
the adjustment (1) issuing to the Holder of any Warrant exercised after the date
of the event that requires the adjustment and before completion of the Appraisal
Procedure and the determination of the adjustment, the shares of capital stock
issuable upon such exercise by reason of the adjustment required by such event
and issuing to such Holder only the shares of capital stock issuable upon such
exercise before giving effect to such adjustment and (2) paying to such Holder
any amount in cash in lieu of a fractional share of capital stock pursuant to
Section 2.3 above; provided, however, that the Company shall deliver to such
Holder an appropriate instrument or due bills evidencing such Holder's right to
receive such additional shares or such cash.

                  4.8 Adjustment of Number of Shares Purchasable. Upon any
adjustment of the Exercise Price as provided in Sections 4.1, 4.3, 4.4 and 4.5
Holders of the Warrants shall thereafter be entitled to purchase upon the
exercise thereof, at the Exercise Price resulting from such adjustment, the
number of shares of Warrant Stock (calculated to the nearest 1/100th of a share)
obtained by multiplying the Exercise Price in effect immediately prior to such
adjustment by the number of shares of Warrant Stock issuable on the exercise
hereof immediately prior to such adjustment and dividing the product thereof by
the Exercise Price resulting from such adjustment.

<PAGE>

                  4.9      Notice of Adjustment of Exercise Price.  Whenever the
Exercise Price is adjusted as herein provided:

                           (i) the Company shall compute the adjusted Exercise
         Price in accordance with this Section 4 and shall prepare a certificate
         signed by the treasurer or chief financial officer of the Company
         setting forth the adjusted Exercise Price and showing in reasonable
         detail the facts upon which such adjustment is based, and such
         certificate shall forthwith be filed at the Designated Office; and

                           (ii) a notice stating that the Exercise Price has
         been adjusted and setting forth the adjusted Exercise Price shall
         forthwith be prepared by the Company, and as soon as practicable after
         it is prepared, such notice shall be mailed by the Company at its
         expense to all Holders at its last address as it shall appear in the
         warrant register.

                  4.10 Form of Warrant. Irrespective of and without limiting any
adjustment in the Exercise Price or the number of shares purchasable upon the
exercise of the Warrant, Warrants thereafter issued may continue to express the
same price and number and kind of shares as are stated in the original Warrant.

                  4.11 Exceptions. This Section 4 shall not apply to any shares
of Common Stock (A) issued upon exercise of options granted under the Company's
2004 stock option plan, (B) issued upon exercise of any other options, warrants
or other rights outstanding on the date hereof, (C) issued to officers and
employees pursuant to employment agreements in existence on the date hereof, (D)
issued as consideration when any corporation or business is acquired, merged
into, or becomes part of the Company or a subsidiary of the Company, (E) issued
upon exercise of any options, warrants or other rights assumed by the Company in
connection with a merger or other acquisition, provided, that such options,
warrants or other rights assumed by the Company shall not have been issued in
connection with or in contemplation of such merger or acquisition, (F) issued in
good faith in connection with any other acquisition of assets in an arms-length
transaction between the Company and an unaffiliated third party, (G) issued to,
or pursuant to rights granted to, unaffiliated market makers who enter into
warrant agreements with the Company and the issuance of such shares, or the
exercise of such rights, is (x) subject to the achievement by the market maker
of specified volume milestones in cleared products, and (y) at an issuance, or
exercise, price that is not less than the fair market value of the Common Stock
on the date of grant, or (H) issued to, or pursuant to rights granted to,
unaffiliated landlords, equipment lessors, lenders, other financial
institutions, or other vendors to, or strategic partners of, the Company
(collectively, the "Excluded Stock"); provided, that any shares issuable
pursuant to sections (D), (F) and (H) above in excess of 300,000 shares in the
aggregate, and any shares issuable pursuant to section (G) above in excess of
1,200,000 shares in the aggregate shall not constitute Excluded Stock.

5.       NO IMPAIRMENT; REGULATORY COMPLIANCE AND COOPERATION

         The Company shall not by any action, including, without limitation,
amending its charter documents or through any reorganization, reclassification,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other similar 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 the Holder against impairment. Without limiting the generality of the
foregoing, the Company shall take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of Warrant Stock upon the exercise of this Warrant,
free and clear of all Liens, and shall use its commercially reasonable efforts
to obtain 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.

6.       RESERVATION AND AUTHORIZATION OF COMMON STOCK

                  6.1 The Company shall at all times reserve and keep available
for issuance upon the exercise of the Warrant such number of its authorized but
unissued shares of Common Stock as will be required for issuance of the Warrant
Stock. All shares of Warrant Stock issuable pursuant to the terms of this
Warrant, when issued upon exercise of this Warrant with payment therefor in
accordance with the terms hereof, shall be duly and validly issued and fully
paid and nonassessable, not subject to preemptive rights and shall be free and
clear of all Liens. Before taking any action that would result in an adjustment
in the number of shares of Warrant Stock 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 over such action. If any shares of
Warrant Stock required to be reserved for issuance upon exercise of the Warrant
require registration or qualification with any Governmental Entity under any
federal or state law (other than under the Securities Act or any state
securities law) before such shares may be so issued, the Company will in good
faith and as expeditiously as possible and at its expense endeavor to cause such
shares to be duly registered.

                  6.2 Before taking any action that would cause an adjustment
reducing the Exercise Price below the then par value (if any) of the shares of
Warrant Stock deliverable upon exercise of the Warrant or that would cause the
number of shares of Warrant Stock issuable upon exercise of the Warrant to
exceed (when taken together with all other Outstanding shares of Common Stock)
the number of shares of Common Stock that the Company is authorized to issue,
the Company will take any corporate action that, in the opinion of its counsel,
is necessary in order that the Company may validly and legally issue the full
number of fully paid and nonassessable shares of Warrant Stock issuable upon
exercise of the Warrant at such adjusted exercise price.

which approval of any stockholders of the Company is required, or of the sale or
transfer of all or substantially all of the assets of the Company (except (i) a
merger or other reorganization in which the Company shall be the surviving
corporation and holders of Common Stock receive no consideration in respect of
their shares and (ii) a merger of the Company into a wholly owned subsidiary of
the Company, the principal purpose of which, in the good faith determination of
the Board of Directors, is to change the state of incorporation of the Company);
or

                  (c)      of the voluntary or involuntary dissolution,
liquidation or winding up of the Company;

                  (d) the Company or any Subsidiary shall commence a tender
offer for all or a portion of the Outstanding shares of Common Stock (or shall
amend any such tender offer to change the maximum number of shares being sought
or the amount or type of consideration being offered therefore);

then the Company shall cause to be filed at the Designated Office, and shall
cause to be mailed to NYMEX at its last address as it shall appear in the
warrant register, (i) at least twenty (20) days prior to the applicable record
or effective date hereinafter specified, a notice stating (x) the date on which
a record is to be taken for the purpose of such dividend, distribution or
granting of rights or warrants, or, if a record is not to be taken, the date as
of which the holders of Common Stock of record who will be entitled to such
dividend, distribution, rights or warrants are to be determined, or (y) the date
on which such reclassification, consolidation, merger, share exchange, sale,
transfer, dissolution, liquidation or winding up is expected to become

of record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,

notice stating the date on which such tender offer commenced, the date on which
such tender offer is scheduled to expire unless extended, the consideration
offered and the other material terms thereof (or the material terms of the
amendment thereto. Such notice shall also set forth such facts with respect
thereto as shall be reasonably necessary to indicate the effect of such action
(to the extent such effect may be known at the date of such notice) on the
Exercise Price and the number and kind or class of shares or other securities or
property which shall be deliverable or purchasable upon the occurrence of such
action or deliverable upon exercise of the Warrant. Neither the failure to give
any such notice nor any defect therein shall affect the legality or validity of
any action described in clauses (a) through (d) of this Section 7.1.

                  7.2 Taking of Record. In the case of all dividends or other
distributions by the Company to the holders of its Common Stock with respect to
which any provision hereof refers to the taking of a record of such holders, the
Company will in each such case take such a record and will take such record as
of the close of business on a Business Day.

                  7.3 Closing of Transfer Books. The Company shall not at any
time close its stock transfer books so as to result in preventing or delaying
the exercise of the Warrant.

                  7.4 Warrant Holder Not Deemed a Stockholder. The Company may
deem and treat the registered Holder of the Warrant as the absolute owner
thereof (notwithstanding any notation of ownership or other writing thereon made
by anyone), for the purpose of any exercise thereof and for all other purposes,
and neither the Company nor any agent thereof shall be affected by any notice to
the contrary. Accordingly, the Company shall not be bound to recognize any
equitable or other claim to, or interest in, the Warrant on the part of any
Person other than such registered Holder, whether or not it shall have express
or other notice thereof. Prior to the valid exercise of the Warrant, no Holder
of the Warrant, as such, shall be entitled to any rights of a stockholder of the
Company, including, without limitation, the right to vote or to consent to an
action of the stockholders, to receive dividends or other distributions, to
exercise any preemptive right, or to receive any notice of meetings of
stockholders and, except as otherwise provided in the Agreement, shall not be
entitled to receive any notice of any proceedings of the Company.

8.       OFFICE OF THE COMPANY

         As long as the Warrant remains outstanding, the Company shall maintain
an office or agency, which may be the principal executive offices of the Company
(the "Designated Office"), where the Warrant may be presented for exercise,
registration of transfer, division or combination as provided in this Warrant.
Such Designated Office shall initially be the office of the Company at 465
Columbus Avenue, Valhalla, New York 10595. The Company may from time to time
change the Designated Office to another office of the Company or its agent
within the United States by notice given to all registered Holders at least ten
(10) Business Days prior to the effective date of such change.

9.       MISCELLANEOUS

                  9.1 No Implied Waivers. No failure or delay by any party in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The rights and remedies herein provided shall be cumulative and not exclusive of
any rights or remedies provided by law.

                  9.2 Notices. All notices, requests, consents and other
communications required or permitted hereunder shall be in writing and shall be

                  9.3 Limitation of Liability. No provision hereof, in the
absence of affirmative action by the Holder to purchase shares of Warrant Stock,
and no enumeration herein of the rights or privileges of the Holder hereof,
shall give rise to any liability of such Holder to pay the Exercise Price for
any Warrant Stock other than pursuant to an exercise of this Warrant or any
liability as a stockholder of the Company, whether such liability is asserted by
the Company or by creditors of the Company.

                  9.4 Remedies. Each Holder of Warrants and/or Warrant Stock, in
addition to being entitled to exercise its rights granted by law, including
recovery of damages, shall be entitled to specific performance of its rights
provided 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, in an action for specific
performance, to waive the defense that a remedy at law would be adequate.

                  9.5 Successors and Assigns. This Warrant and the rights and
obligations evidenced hereby shall inure to the benefit of and be binding upon
the successors of the Company and the permitted successors and assigns of the
Holder hereof.

                  9.6 Amendment. This Warrant and all other Warrants may be
modified or amended or the provisions hereof waived only with the written
consent of the Company and the Holder or, in the case of any transfer of this
Warrant to multiple Persons, the written consent of the Company and two-thirds
of the Holders. Notwithstanding the foregoing, without a Holder's written
consent no such modification, amendment or waiver shall affect adversely such
Holder's rights hereunder in a discriminatory manner inconsistent with its
adverse effects on rights of other Holders hereunder (other than as reflected by
the different number of shares of Warrant Stock held by such Holders). This
Warrant cannot be changed, modified, discharged or terminated by oral agreement.

                  9.7 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
provision or the remaining provisions of this Warrant.

                  9.8 Headings. The headings and other captions in this Warrant
are for the convenience and reference only and shall not be used in
interpreting, construing or enforcing any provision of this Warrant.

                  9.9 Governing Law; Jurisdiction; Waiver of Jury Trial. The
Internal Laws, and not the laws of conflicts (other than Section 5 1401 of the
general obligations law of the state of New York), of New York shall govern the
enforceability and validity of this warrant, the construction of its terms and
the interpretation of the rights and duties of the Company. Any suit, action or
proceeding seeking to enforce any provision of, or based on any matter arising
out of or in connection with, this Warrant or any other Warrant or the
transactions contemplated hereby may be brought in any federal or state court
located in the County and State of New York, and each of the parties hereby
consents to the jurisdiction of such courts (and of the appropriate appellate
courts therefrom) in any such suit, action or proceeding and irrevocably waives,
to the fullest extent permitted by law, any objection which it may now or
hereafter have to the laying of the venue of any such suit, action or proceeding
in any such court or that any such suit, action or proceeding which is brought
in any such court has been brought in an inconvenient forum. Process in any such
suit, action or proceeding may be served on any party anywhere in the world,
whether within or without the jurisdiction of any such court. Without limiting
the foregoing, each party agrees that service of process on such party as
provided in Section 9.2 shall be deemed effective service of process on such
party.

                  9.10 Aggregation of Stock. All Warrant Stock held by or

agreement with respect to the subject matter hereof and supersedes and replaces
all other prior agreements, written or oral, with respect to the subject matter
hereof.

                  9.12     Waiver of Jury Trial.  EACH OF THE PARTIES HERETO
HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL

                                             W I T N E S S E T H:

                  WHEREAS, the Borrower and the Lender are parties to the Loan
Agreement;

                  WHEREAS, Section 2.b.2 of the Loan Agreement provides, in
part, that following the first financing, the Borrower shall prepay Lender a
certain portion of the Loan (as defined in the Loan Agreement) and shall begin
to pay interest on the remaining unpaid balance;

                  WHEREAS, the Borrower and the Lender are parties to a Stock
and Warrant Purchase Agreement, dated as of April 10 , 2007, (the "Stock and
Warrant Purchase Agreement") by and among the Borrower, the Lender, NYMEX
Holdings, Inc. ("NYMEX"), Edward O'Connor, through Ridgecrest Capital, Inc., a
New York corporation and Kevin Cassidy, through Pierpont Capital, Inc., a New
York corporation; and

                  WHEREAS, Section 8.2(e) of the Stock and Warrant Purchase
Agreement provides that the execution and delivery by Lender of this Waiver is a
condition to NYMEX's obligation to close the transactions contemplated by the
Stock and Warrant Purchase Agreement; and

                  WHEREAS, closing of the transactions contemplated by the Stock
and Warrant Purchase Agreement will confer substantial benefits upon both the
Borrower and the Lender;

                  NOW THEREFORE, in consideration of the premises, the mutual
covenants contained herein and the benefits to be conferred upon each as a
result of the closing of the transactions contemplated by the Stock and Warrant

                  1. Definitions. Unless otherwise defined herein, terms defined
in the Loan Agreement shall have the meanings assigned to them in the Loan
Agreement when used herein.

                  2. Waiver to Loan Agreement. The Lender hereby waives any
requirement under the Loan Agreement (a) that the Company make any prepayment of
principal thereunder, or (b) that the Company begin to pay interest thereunder,

                  4. Miscellaneous.

                           (a) Governing Law. The validity, interpretation,
         performance and enforcement of this Agreement shall be governed by the
         laws of the State of New York, without giving effect to the laws, rules
         or principles of such State regarding conflicts of laws (other than
         Section 5-104 of the General Obligations Laws of the State of New
         York).

                           (b) Benefit Assignment. This Waiver shall be binding
         upon and shall inure to the benefit of Borrower and Lender and their
         respective successors and permitted assigns. Neither Borrower nor
         Lender may assign any of their respective rights or delegate any of
         their respective duties under this Waiver without the prior written
         consent of the other party and any assignment or delegation of this
         Waiver by either party without the prior written consent of the other
         party shall be void.

                           (c) Third Party Beneficiaries. NYMEX shall be a third
         party beneficiary of the waiver by Lender set forth in Section 2 of
         this Waiver.

                           (d) Severability; Reformation. If a court of
         competent jurisdiction determines that any provision of this Waiver is
         invalid, unenforceable or illegal for any reason, such determination
         shall not affect or impair the validity, legality and enforceability of

                              W I T N E S S E T H:

                  WHEREAS, Employer is engaged in the business of providing
trading and brokerage services to brokerage firms, financial institutions,
energy traders, and hedge funds, and developing an automated electronic trading

                  WHEREAS, Employer and Employee are the parties to an

         2. Term of Employment. Employer hereby employs Employee and Employee

In the absence of such renewal, this Agreement shall terminate at the end of the
then current Term.

meetings at the request of the directors; and

                  (e) use of his best efforts to carry into effect the policies,

Employee agrees that he shall devote no less than eighty (80%) percent of his
working time to carrying out his duties and obligations hereunder. It is

Employee shall be permitted to continue to be active in and pursue other
business activities and opportunities (whether or not now existing) provided,
that while employed hereunder he shall abide by the Restrictive Covenants set
forth in Section 7 below. Moreover, and subject to the first sentence of this
paragraph and the Employee's duty of loyalty to Employer, it is understood that
Employee may engage in personal activities of a civic, charitable or educational
nature and may manage his personal investments.

         4. Place of Performance. Employee's place of employment shall be

                  (a) Employee's gross salary during the Employment Period

                           (i)  upon entering into this agreement, $20,833;

                           (ii) from October 30, 2005 to December 31, 2005,
                                $46,875;

                                and

                           (vi) from January 1, 2009 to December 31, 2009:
                                $350,000;

<PAGE>

                  (b) During the Employment Period and beginning with the first
month of the quarter in which the amount payable to Employee, pursuant to the
Addendum to Master Services Agreement dated April 12, 2005, is fully paid,
Employer shall pay Employee (i) cash compensation amounting to five percent (5%)
of Gross Revenues of Employer, and (ii) stock compensation ("Stock
Compensation") amounting to two percent (2%) of the Gross Revenues of Employer
(together the "Variable Compensation"). Gross Revenue is defined as the total
gross revenue related to any all aspects of the brokerage business, including
incentive received from exchanges, based on generally accepted accounting
principles. Stock will be granted at fair value at the date of grant. The
Variable Compensation will be paid (in the case of cash) and issued (in the case
of stock) on a quarterly basis. It is understood that shares of Employer's
common stock constituting the Stock Compensation will be "restricted stock," as
such term is defined in Rule 144 of the Securities and Exchange Commission.

                  (c) Employer shall issue common stock purchase options to
Employee to purchase that number of shares of common stock equal to twenty
percent (20%) of the number of shares of common stock issuable under warrants
which become exercisable pursuant to any Order Flow Agreements. Order Flow
Agreements being those agreements in which the Employer has agreed to issue
warrants to an entity based on the volume of orders that such entity has placed
with the Employer. Such options will be Non-Statutory Stock Options granted
under Employer's 2004 Stock Option Plan (the "Plan") at fair value at the date
of grant and will be fully-vested upon grant.

                  (d) Employer shall issue to Employee 5,000 common stock
purchase options each time a firm registers with and executes its first 10,000
lots on Employer's OPEX platform. The total number of options issuable under
this Section 5(d) will be limited to 2,500,000. Such options will be
Non-Statutory Options granted under the Plan at fair value at the date of grant
and will be fully-vested upon grant.

                  (e) Employee shall be entitled to paid annual vacation,
personal leave and holidays in accordance with the policies of Employer.
Employee will be entitled to participate in health, welfare, and pension plans
and any other employee benefit plan of Employer on the same basis as such
benefits are generally available to similarly situated employees of Employer.

                  (f) Employer will advance to or reimburse Employee for all
reasonable travel and entertainment and other reasonable expenses incurred by
the Employee in connection with his performance under this Agreement upon
submission of written or printed receipts in accordance with Employer's usual
and customary policy. Employer agrees that Employee's travel by first class air
travel and by executive limousine ground transportation are reasonable expenses.

                  (g) Employer shall advance to or reimburse Employee for the
annual or monthly premium of Employee's life insurance policy of one million
dollars ($1,000,000) where the beneficiary is the Employee's estate (immediate
family), provided that Employee submits to Employer a copy of the invoice for
such premium upon request.

<PAGE>

                  (h) Upon notice to be given to Employee not less than thirty
(30) days prior to the expiration of the Term, Employer shall have the right to
require that Employee continue to abide by the Restrictive Covenants set forth
in Sections 7(b) and (c) below following the expiration of the Term, in which
case Employer shall continue to pay Employee his Fixed Compensation, at the rate
in effect on the last day of the Term, in accordance with Employee's regular
payroll policies and subject to usual payroll deduction provided by law, through
the last day of the Restrictive Period (as defined in Section 7(b) below). For
the avoidance of doubt, an early termination of this Agreement pursuant to
Section 6 below does not constitute the expiration of the Term.

         6. Early Termination. This Agreement may be terminated by either party
at any time before the expiration of the Term in accordance with the terms and
conditions set forth in this Section 6.

                  (a) If Employee resigns from his employment under this
Agreement without Good Reason, as defined below, or if Employer terminates
Employee's employment for Cause, as defined below, Employer shall have no
financial obligation to Employee except to pay his Fixed Compensation through
the date of termination and continue his employee benefits through such date.
Employer shall give Employee written notice of a termination for Cause, and
Employee shall give written notice to Employer of resignation for Good Reason.
For purposes of this Agreement, "Cause" shall mean (i) the Employee's willful
misconduct in the performance of his duties hereunder, provided that Employer
shall have given written notice of such willful misconduct to Employee and
Employee shall not have substantially cured such willful misconduct within
fifteen (15) days after his receipt of such notice; (ii) a non-appealable
conviction of a felony; (iii) issuance of a final consent decree,
cease-and-desist or similar order against Employee prohibiting Employee from
engaging in the securities and/or commodities business or (iv) Employee's breach
of any of the Restrictive Covenants set forth in Section 7 below. For purposes
of this Agreement, "Good Reason" shall mean the occurrence of any of the
following: (A) Employer shall have materially defaulted in its obligations
hereunder; (B) a material diminution in Employee's authority, or
responsibilities, or (C) a change in Employee's Place of Performance without
Employee's prior written consent.

                  (b) Upon the sale or merger or other business combination of
Employer and another company or companies (excluding NYMEX Holdings, Inc. or its
affiliates), Employee will be entitled to a lump sum payment of 50% of the
unpaid Fixed Compensation should he desire not to be employed with the new or
successor entity.

                  (c) If Employee becomes incapable, by reason of death or
Disability, as defined below, of performing his duties under this Agreement,
Employer may terminate Employee on the following terms. Employer will pay to
him, or to a person duly authorized to act on his or his estate's behalf, a lump
sum equal to the sum of any unpaid Fixed Compensation accrued to the date of
termination (the "Section 6(d) Sum"). In such circumstances, payment of the
Section 6(d) Sum shall satisfy all financial obligations of Employer to Employee
under this Agreement, but Employee's employment hereunder shall continue for the
duration of the condition that occasioned the Disability, after which his
employment for all purposes shall cease. For purposes of this Agreement,
"Disability" shall mean the inability of Employee, by reason of physical or
mental illness or injury, substantially to perform his duties hereunder for a
period of time exceeding 180 days in the aggregate during any period of twelve
consecutive months. Employer shall give Employee or a person duly authorized to
act on his behalf written notice of a termination based on Disability.

                                       4
<PAGE>

                  (d) Employee shall have no duty to mitigate Employer's damages
or losses, if any, with respect to any payments due him pursuant to this Section
6, by seeking or accepting other employment. Moreover, should Employee seek and
accept other employment no amounts payable to Employee by a subsequent employer
shall be deemed to offset to any amounts owed by Employer to Employee under this
Agreement.

                  (e) For the avoidance of doubt, if either Employer terminates
Employee's employment without Cause or Employee resigns for Good Reason,
Employee shall be entitled to all amounts hereunder as though Employee continued
to work until five (5) years after the Commencement Date.

         7. Restrictive Covenants. Employee acknowledges that the business in
which Employer is engaged is intensely competitive and: (i) by reason of
Employee's appointment and duties, he will be privy to substantial and vital
confidential information of Employer, not generally published or available to
the public, concerning the organization, business and affairs, products and
technology, and customers of Employer, including but not limited to, business
plans, operational methods, financial information and projections, technical
processes and data, product development plans, research and development, lists
of customers, interests and needs of customers, business plans and policies,
overhead and cost information, profit margins, pricing methods or prices
considered or actually charged, lists and records of sales and contracts,
computer software applications and other programs, source codes, object codes,
marketing techniques and materials, marketing and development plans, price
lists, pricing policies, personnel information and other trade secrets (the
"Confidential Information"); (ii) the disclosure of any of the foregoing to
existing or potential competitors of Employer would place Employer at a serious
competitive disadvantage and could do serious damage to the business of
Employer; and (iii) by Employee's training, experience and expertise, Employee's
services to Employer will be extraordinary, special and unique. Accordingly,
Employee willingly agrees to be bound by the following restrictions:

                  (a) During the Term and at all times after the termination of
Employee's employment with Employer for any reason (including the expiration of
the Term), Employee shall not, directly or indirectly, whether individually, as
an officer, director, employee, consultant, owner, investor, partner or
stockholder of any business, or in any other capacity, make known, disclose,
furnish, make available or utilize any of the Confidential Information, other
than in the proper performance of the duties contemplated herein. Employee
agrees to return all Confidential Information, including all photocopies,
extracts and summaries thereof, and any such information stored electronically
or in any other manner to Employer at any time upon request by Employer and upon
the termination of Employee's employment for any reason (including the
expiration of the Term). Nothing contained in this Section 7(a) shall be deemed
to preclude Employee from: (i) using his own general skills, knowledge and
experience; (ii) using or disclosing any Confidential Information which becomes
public through no fault of Employee; or (iii) disclosing Confidential
Information pursuant to subpoena, court order or legal process, provided that
Employee gives Employer advance written notice of the required disclosure so
that Employer may, if it wishes, seek an appropriate protective order.

                                       5
<PAGE>

                  (b) During the Term and for a period of nine (9) months
following the termination of Employee's employment with Employer for any reason
(including the expiration of the Term if Employer makes the election
contemplated by Section 5(h) above) (the "Restrictive Period"), Employee shall
not, directly or indirectly, whether as officer, director, employee, consultant,
owner, investor, partner or stockholder, be engaged in or have any financial
interest in (other than an interest of less than five percent (5%) of the stock
of a publicly traded company) or affiliation with or render any services to or
for any person, firm, company or organization which provides "Competitive
Services" (as defined below) to brokerage firms, other financial institutions
providing energy brokerage services or clearinghouses, anywhere in the United
States, it being understood and acknowledged by Employee that Employer conducts
business and offers Competitive Services on a nationwide basis. The term
Competitive Services shall mean natural gas and other energy brokerage services.
Notwithstanding the foregoing, it shall not be a violation of this Section 7(b)
for Employee to become an officer, director, employee, consultant, owner,
investor, partner or stockholder of any person, firm, company or organization
which provides "Competitive Services" if, and only if, Employee's primary
responsibilities to or for such person, firm, company or organization do not
involve, and do not in any significant manner relate to, providing Competitive
Services to brokerage firms, other financial institutions providing energy
brokerage services or clearinghouses, anywhere in the United States.

                  (c) During the Restrictive Period, Employee shall not,
directly or indirectly, for his benefit or for the benefit of any person, firm
or entity (other than Employer):

                           (i) cause or attempt to cause any Customer or
Prospective Customer of Employer on whom Employee called or with whom Employee
became acquainted during employment with Employer to obtain Competitive Services
from any person, firm, company or organization other than Employer or to cease
doing business with, or reduce the amount of Competitive Services obtained from,
Employer. For purposes of this Agreement, "Customer" shall mean any brokerage
firm, financial institution, energy trader, hedge fund or other entity which was
a customer of or had an account with Employer during the one (1) year period
preceding Employee's termination of employment for any reason (including the
expiration of the Term). For purposes of this Agreement, "Prospective Customer"
shall mean any brokerage firm, financial institution, energy trader, hedge fund
or other entity for which Employer had submitted a written proposal to provide
services within the one (1) year period preceding Employee's termination of
employment for any reason (including the expiration of the Term); or

                           (ii) enter into any partnership, limited liability
company, corporation, new or joint venture or similar arrangement with, or hire
or retain or attempt to hire or retain, any person who is, or at any time during
the one (1) year period preceding the termination of Employee's employment with
Employer for any reason (including the expiration of the Term), was an employee
of or consultant to Employer, without the prior written consent of the Employer,
such consent to be within Employer's sole and absolute discretion.

                  (d) Employee acknowledges that the restrictions specified in
this Section 7 are reasonable in view of the nature of the business in which
Employer is engaged, Employee's position with Employer, and Employee's knowledge
of Employer's business, and that any breach of this Section 7 may cause Employer
irreparable harm for which there is no adequate remedy at law, and as a result
of this, Employer will be entitled to seek the issuance by a court of competent
jurisdiction of an injunction, restraining order or other equitable relief in
favor of Employer, without the necessity of posting a bond, restraining Employee
from committing or continuing to commit any such violation. Any right to obtain
an injunction, restraining order or other equitable relief hereunder will not be
deemed to be a waiver of any right to assert any other remedy Employer may have
at law or in equity.

                                       6
<PAGE>

                  (e) Employee acknowledges and agrees that the duration and
geographic scope of the covenants contained in this Sections 7 are fair and
reasonable. Accordingly, Employee agrees that, in the event that any of the
covenants contained in this Section 7 is nevertheless judicially determined to
be unenforceable because of the duration or geographic scope thereof, the court
making such determination is hereby directed to reduce such duration and/or
scope to the extent necessary to enable such court to determine that such
covenant is reasonable and enforceable, and to enforce such covenant as so
amended.

                  (f) The provisions of this Section 7 shall survive the
termination of Employee's employment for any reason (including the expiration of
the Term) and this Agreement.

         8. Termination of Consulting Agreement. Upon execution of this
Agreement, the Consulting Agreement, dated April 1, 2004 between the Employer
and the Employee, which is pursuant to the Master Services Agreement, dated
April 1, 2004, between the Employer and Capital Energy Services LLC, is
terminated retroactively on October 15, 2005. However, all other terms of the
Master Services Agreement, other than those relating to the Consultant, will
remain unchanged.

         9. Governing Law; Jurisdiction; Venue. This Agreement shall be governed
by and is to be construed and enforced in accordance with the internal laws of
the State of New York without regard to principles of conflicts of laws. Any
action to enforce any term hereof shall be brought in the state or federal
courts located in the City of New York, State of New York, to which jurisdiction
and venue all parties hereby submit themselves.

         10. Notices. All notices required to be given under this Agreement
shall be in writing and shall be deemed effective when delivered in person, by
facsimile transmission, overnight mail service or by certified U.S. mail,
addressed, in the case of Employee, to him at his residential address as
reflected in the Employer's personnel records or, in the case of Employer, to
555 Pleasantville Road, South Building, Suite 110, Briarcliff Manor, NY 10510,
or to such other address as Employee or Employer may designate in writing to the
other party.

         11. Miscellaneous.

                  (a) This Agreement contains the entire agreement and
understanding between the parties and supersedes all other prior agreements,
discussions, negotiations, commitments, and understandings between them with
respect to the subject matter hereof. There are no representations, agreements,
arrangements or understandings, oral or written, between the parties concerning
the subject matter hereof which are not fully expressed herein.

                  (b) No waiver by either party of or failure to assert any
provision or condition of this Agreement by him or it to be performed or right
to be exercised shall be deemed a waiver of such or similar or dissimilar
provisions and conditions or rights at the same time or any prior or subsequent
time.

                  (c) This Agreement shall be binding upon, and inure to the
benefit of, the parties hereto and their heirs, successors, assigns and personal
representations. In no event may Employee assign any rights or duties under this
Agreement and in no event may Employer assign any rights or duties under this
Agreement without the prior written authorization of Employee, provided,
however, that Employer may assign its rights under this Agreement in connection
with any merger, consolidation or sale of substantially all of its assets
subject to Section 6(b).

                  (d) Each in consultation with its respective legal counsel,
Employer and Employee have participated jointly in the negotiation and drafting
of this Agreement. In the event an ambiguity or question of intent or
interpretation arises, this Agreement shall be construed as if drafted jointly
by the parties hereto and no presumption or burden of proof shall arise favoring
or disfavoring any party by virtue of the authorship of any of the provisions of
this Agreement.

                  (e) Employer shall indemnify and hold Employee harmless with
respect to any liability, loss or expense, including reasonable attorneys' fees
("Loss") (Employee shall have the right to choose such attorneys, subject to the
consent of Employer, which consent shall not be unreasonably withheld) incurred
by him, as a result of any claim relating to or arising out of the performance
of duties pursuant to this Agreement, provided, however, that if it is
determined that the Loss arose as a result of Employee's willful misconduct or
gross negligence, then Employee shall not be entitled to indemnification for
such Loss and Employee shall be required promptly to return to Employer any
amounts paid by Employer pursuant to this Section 11(e).

                  (f) In the event that any one or more of the provisions of
this Agreement shall be held to be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remainder hereof shall not in any
way be affected or impaired thereby and any such provision or provisions shall
be enforced to the fullest extent permitted by law. Moreover, if any one or more
of the provisions contained in this Agreement are held to be excessively broad
as to duration, scope, activity or subject, such provisions will be construed by
limiting and reducing them so as to be enforceable to the maximum extent
compatible with applicable law.

The Company pays variable compensation to its Chief Executive Officer pursuant
to his employment agreement.

The Company may pay bonuses on an ad hoc basis, based on performance, to certain

                                  Schedule 6.26

                           Related-Party Transactions

1. Travel and expense reimbursement in the ordinary course of business.

2. The Company was party to a Master Services Agreement with CES pursuant to
which the Company provided brokerage services on the floor of the New York
Mercantile Exchange. Mr. O'Connor, the Company's President, is a 50% stockholder
of CES. Mr. Cassidy, the Company's Chief Executive Officer is the Managing
Director and a 50% stockholder of CES. Pursuant to this arrangement, the Company
was paying to CES a minimum annual fixed fee of $50,000 and assuming all
expenses directly incurred by CES's associated floor brokerage services.
Additionally, the Company owes to CES $1,525,000 payable on April 1, 2014.
However, upon a Capital Raise (as defined below), the Company will pay up to
10.67% of the amount raised during the Capital Raise, up to $762,500, to CES,
with the remaining principal and accrued interest of 12% from the date of the
Capital Raise payable on April 1, 2014.

Pursuant to this arrangement, our share of revenues and expenses of the floor
brokerage services amounted to approximately $3.6 million and $741,000,
respectively, during 2006, and $2.0 million and $860,000, respectively, during
2005. We have received $2.6 million and $1.0 million from CES in connection with
such floor brokerage services during 2006 and 2005, and CES owes us
approximately $488,000 as of December 31, 2006. This agreement was terminated in
January 2007 and our floor operations are now assumed by a subsidiary, OPEX
International, Inc. In April 2005, CES assigned its rights to the Company's
liability of $1,525,000 equally to Mr. O'Connor and Mr. Cassidy, co-owners of
CES.
3. In April 2005, the Company modified the terms of the agreements under which
the Company initially owed $5,762,753, $765,000 and $765,000 to Mark Nordlicht,
the Company's Chairman of the Board, Mr. Cassidy and Mr. O'Connor, respectively.
The modified terms provide that, among other things, in the event the Company
raises more than $1,000,000 additional equity or debt financing (a "Capital
Raise"), the interest rate accrued after such event will be reduced from 12% to
4.68%. In 2006, we modified the terms of the agreements to allow prepayments at
our discretion.

In connection with the modified terms, the Company made principal repayments of
$400,000 and $177,243 on the amount due to Mr. Nordlicht during 2006 and 2005,
respectively, of which $69,638 was offset in 2005 against an accounts receivable
of one of the Company's clients, which is not affiliated with Mr. Nordlicht.
Additionally, the Company made principal repayment of $558,697 and $203,803 on
the amount due to Mr. Cassidy during 2006 and 2005, respectively, and $200,000
and $53,803 on the amount due to Mr. O'Connor, during 2006 and 2005,
respectively.

4. The Company has recognized revenues from brokerage commissions of
approximately $3,480, $206,119 and $63,000 during 2006 and $75,000, $9,000 and
$21,000, during 2005, from Northern Lights Energy LLC, Platinum Partners, L.P.
and Fenmore Holdings LLC, respectively, entities in which Mr. Nordlicht is the
managing partner or a stockholder. The aggregate amount owed to us from such
entities amounted to approximately $289,000 as of December 31, 2006.

5. Pursuant to an agreement providing for the reimbursement of certain
administrative expenses for services provided to a coffee bean roaster, Sleepy
Hollow Coffee Roasters, Inc. ("Sleepy Hollow"), a company owned by Messrs.
O'Connor and Cassidy, the Company charged an administrative fee of $17,000 and
$17,000 to Sleepy Hollow during 2006 and 2005, respectively.
