     use its properties and assets and to carry on its business as currently
     conducted. Neither the Company nor any Subsidiary is in violation of any of
     the provisions of its respective certificate or articles of incorporation,

     and the Subsidiaries is duly qualified to do business and is in good
     standing as a foreign corporation or other entity in each jurisdiction in
     which the nature of the business conducted or property owned by it makes
     such qualification necessary, except where the failure to be so qualified
     or in good standing, as the case may be, would not, individually or in the
     aggregate, have or reasonably be expected to result in a Material Adverse
     Effect.

                      (c) AUTHORIZATION; ENFORCEMENT. The Company has the
     requisite corporate authority to enter into and to consummate the
     transactions contemplated by each of the Transaction Documents to which it

     thereunder. The execution and delivery of each of the Transaction Documents
     to which it is a party by the Company and the consummation by it of the
     transactions contemplated hereby and thereby have been duly authorized by
     all necessary action on the part of the Company and no further consent or
     action is required by the Company, its Board of Directors or its
     stockholders. Each of the Transaction Documents to which it is a party has
     been (or upon delivery will be) duly executed by the Company and is, or
     when delivered in accordance with the terms hereof, will constitute, the
     valid and binding obligation of the Company enforceable against the Company
     in accordance with its terms, except as may be limited by (i) applicable
     bankruptcy, insolvency, reorganization or other laws of general application
     relating to or affecting the enforcement of creditors rights generally, and

     the Company's or any Subsidiary's certificate or articles of incorporation,

     constitute a default (or an event that with notice or lapse of time or both
     would become a default) under, or give to others any rights of termination,
     amendment, acceleration or cancellation (with or without notice, lapse of
     time or both) of, any agreement, credit facility, debt or other instrument
     (evidencing a Company or Subsidiary debt or otherwise) or other
     understanding to which the Company or any Subsidiary is a party or by which
     any property or asset of the Company or any Subsidiary is bound, or
     affected, except to the extent that such conflict, default, termination,
     amendment, acceleration or cancellation right would not reasonably be
     expected to have a Material Adverse Effect, or (iii) result in a violation
     of any law, rule, regulation, order, judgment, injunction, decree or other
     restriction of any court or governmental authority to which the Company or
     a Subsidiary is subject (including, assuming the accuracy of the
     representations and warranties of the Investors set forth in Section 3.2
     herof, federal and state securities laws and regulations and the rules and
     regulations of any self-regulatory organization to which the Company or its

     price adjustment provisions contained in any security issued by the Company

     Common Stock or other securities to any Person (other than the Investors)

                                       8

     from registration under Regulation D under the Securities Act in connection
     with the offer and sale by the Company of the Securities as contemplated
     hereby or (ii) cause the offering of the Securities pursuant to the

     than Excluded Investors) makes or has made any representations or
     warranties with respect to the transactions contemplated hereby other than

     any jurisdiction, and the officers of the Company know of no basis for any

     investor" as defined in Rule 501(a) under the Securities Act or a
     "qualified institutional buyer" as defined in Rule 144A(a) under the
     Securities Act. Such Investor is not a registered broker dealer registered
     under Section 15(a) of the Exchange Act, or a member of the NASD, Inc. or
     an entity engaged in the business of being a broker dealer. Except as
     otherwise disclosed in writing to the Company on Exhibit B-2 (attached
     hereto) on or prior to the date of this Agreement, such Investor is not
     affiliated with any broker dealer registered under Section 15(a) of the
     Exchange Act, or a member of the NASD, Inc. or an entity engaged in the
     business of being a broker dealer.

                      (d) EXPERIENCE OF SUCH INVESTOR. Such Investor, either
     alone or together with its representatives 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
     the Securities, and has so evaluated the merits and risks of such
     investment. Such Investor understands that it must bear the economic risk
     of this investment in the Securities indefinitely, and is able to bear such
     risk and is able to afford a complete loss of such investment.

                      (e) ACCESS TO INFORMATION. Such Investor acknowledges that
     it has reviewed the Disclosure Materials and has been afforded: (i) the
     opportunity to ask such questions as it has deemed necessary of, and to
     receive answers from, representatives of the Company concerning the terms
     and conditions of the offering of the Securities and the merits and risks
     of investing in the Securities; (ii) access to information (other than
     material non-public information) about the Company and the Subsidiaries and
     their respective financial condition, results of operations, business,
     properties, management and prospects sufficient to enable it to evaluate
     its investment; and (iii) the opportunity to obtain such additional
     information that the Company possesses or can acquire without unreasonable
     effort or expense that is necessary to make an informed investment decision
     with respect to the investment. Neither such inquiries nor any other
     investigation conducted by or on behalf of such Investor or its
     representatives or counsel shall modify, amend or affect such Investor's
     right to rely on the truth, accuracy and completeness of the Disclosure
     Materials and the Company's representations and warranties contained in the
     Transaction Documents. Such Investor acknowledges receipt of copies of the
     SEC Reports.

                                       17

<PAGE>

                      (f) NO GOVERNMENTAL REVIEW. Such Investor understands that
     no United States federal or state agency or any other government or
     governmental agency has passed on or made any recommendation or endorsement
     of the Securities or the fairness or suitability of the investment in the
     Securities nor have such authorities passed upon or endorsed the merits of
     the offering of the Securities.

                      (g) NO CONFLICTS. The execution, delivery and performance
     by such Investor of this Agreement and the consummation by such Investor of
     the transactions contemplated hereby will not (i) result in a violation of
     the organizational documents of such Investor or (ii) conflict with, or
     constitute a default (or an event which with notice or lapse of time or
     both would become a default) under, or give to others any rights of
     termination, amendment, acceleration or cancellation of, any agreement,
     indenture or instrument to which such Investor is a party, or (iii) result
     in a violation of any law, rule, regulation, order, judgment or decree
     (including federal and state securities laws) applicable to such Investor,
     except in the case of clauses (ii) and (iii) above, for such that are not
     material and do not otherwise affect the ability of such Investor to
     consummate the transactions contemplated hereby.

                      (h) ILLEGAL TRANSACTIONS. No Investor, directly or
     indirectly, and no Person acting on behalf of or pursuant to any
     understanding with any Investor, has engaged in any transactions in the
     securities of the Company (including, without limitation, any Short Sales
     involving any of the Company's securities) since the time that such
     Investor was first contacted by the Company, the Agent or any other Person
     regarding this investment in the Company. Such Investor covenants that
     neither it nor any Person acting on its behalf or pursuant to any
     understanding with such Investor will engage, directly or indirectly, in
     any transactions in the securities of the Company (including Short Sales)
     prior to the time the transactions contemplated by this Agreement are
     publicly disclosed. "Short Sales" include, without limitation, all "short
     sales" as defined in Rule 200 promulgated under Regulation SHO under the
     Exchange Act and all types of direct and indirect stock pledges, forward
     sale contracts, options, puts, calls, short sales, swaps, derivatives and
     similar arrangements (including on a total return basis), and sales and
     other transactions through non-U.S. broker-dealers or foreign regulated
     brokers.

                  (i) RESTRICTED SECURITIES. The Investors understand that the
         Securities are characterized as "restricted securities" under the U.S.
         federal securities laws inasmuch as they are being acquired from the
         Company in a transaction not involving a public offering and that under
         such laws and applicable regulations such securities may be resold
         without registration under the Securities Act only in certain limited
         circumstances.

                  (j) LEGENDS. It is understood that, except as provided in
         Section 4.1(b) of this Agreement, certificates evidencing such
         Securities may bear the legend set forth in Section 4.1(b)

                                       18

<PAGE>

                  (k) NO LEGAL, TAX OR INVESTMENT ADVICE. Such Investor
         understands that nothing in this Agreement or any other materials
         presented by or on behalf of the Company to the Investor in connection
         with the purchase of the Securities constitutes legal, tax or
         investment advice. Such Investor has consulted such legal, tax and
         investment advisors as it, in its sole discretion, has deemed necessary
         or appropriate in connection with its purchase of the Securities. Such
         Investor understands that the Agent has acted solely as the agent of
         the Company in this placement of the Securities, and that the Agent
         makes no representation or warranty with regard to the merits of this
         transaction or as to the accuracy of any information such Investor may
         have received in connection therewith. Such Investor acknowledges that
         he has not relied on any information or advice furnished by or on
         behalf of the Agent.

                                   ARTICLE IV
                         OTHER AGREEMENTS OF THE PARTIES

         4.1  TRANSFER RESTRICTIONS.

                      (a) The Investors covenant that the Securities will only
     be disposed of pursuant to an effective registration statement under, and
     in compliance with the requirements of, the Securities Act or pursuant to
     an available exemption from the registration requirements of the Securities
     Act, and in compliance with any applicable state securities laws. In
     connection with any transfer of Securities other than pursuant to an
     effective registration statement or to the Company, or pursuant to Rule
     144(k), the Company may require the transferor to provide to the Company an
     opinion of counsel selected by the transferor, the form and substance of
     which opinion shall be reasonably satisfactory to the Company, to the
     effect that such transfer does not require registration under the
     Securities Act. Notwithstanding the foregoing, the Company hereby consents
     to and agrees to register on the books of the Company and with its transfer
     agent, without any such legal opinion, except to the extent that the
     transfer agent requests such legal opinion, any transfer of Securities by
     an Investor to an Affiliate of such Investor, provided that the transferee
     certifies to the Company that it is an "accredited investor" as defined in
     Rule 501(a) under the Securities Act and provided that such Affiliate does
     not request any removal of any existing legends on any certificate
     evidencing the Securities.

                      (b) The Investors agree to the imprinting, so long as is
     required by this SECTION 4.1(B), of the following legend on any certificate
     evidencing any of the Securities:

         THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND
         EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN
         RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT
         OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY APPLICABLE STATE
         SECURITIES LAWS AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT
         PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES
         ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT
         SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN
         COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS.

                                       19

<PAGE>

Certificates evidencing Securities shall not be required to contain such legend
or any other legend (i) while a registration statement (including the
Registration Statement) covering the resale of the Securities is effective under
the Securities Act, (ii) following any sale of such Securities pursuant to Rule
144 if the holder provides the Company with a legal opinion (and the documents
upon which the legal opinion is based) reasonable acceptance to the Company to
the effect that the Securities can be sold under Rule 144, (iii) if the holder
provides the Company with a legal opinion (and the documents upon which the
legal opinion is based) reasonably acceptable to the Company to the effect that
the Securities are eligible for sale under Rule 144(k), or (iv) if the holder
provides the Company with a legal opinion (and the documents upon which the
legal opinion is based) reasonably acceptable to the Company to the effect that
the legend is not required under applicable requirements of the Securities Act
(including controlling judicial interpretations and pronouncements issued by the
Staff of the SEC). The Company shall cause its counsel to issue the legal
opinion included in the Transfer Agent Instructions to the Transfer Agent on the
Effective Date. Following the Effective Date or at such earlier time as a legend
is no longer required for certain Securities, the Company will no later than
three Trading Days following the delivery by an Investor to the Company or the
Transfer Agent of (i) a legended certificate representing such Securities and
(ii) an opinion of counsel to the extent required by SECTION 4.1(A), deliver or
cause to be delivered to such Investor a certificate representing such
Securities that is free from all restrictive and other legends. The Company may
not make any notation on its records or give instructions to the Transfer Agent
that enlarge the restrictions on transfer set forth in this Section.

         If within three Trading Days after the Company's receipt of a legended
certificate and the other documents as specified in Clauses (i) and (ii) of the
paragraph immediately above, the Company shall fail to issue and deliver to such
Investor a certificate representing such Securities that is free from all
restrictive and other legends, and if on or after such Trading Day the Investor
purchases (in an open market transaction or otherwise) shares of Common Stock to
deliver in satisfaction of a sale by the Investor of shares of Common Stock that
the Investor anticipated receiving from the Company without any restrictive
legend (the "COVERING SHARES"), then the Company shall, within three Trading
Days after the Investor's request, pay cash to the Investor in an amount equal
to the excess (if any) of the Investor's total purchase price (including
brokerage commissions, if any) for the Covering Shares, over the product of (A)
the number of Covering Shares, times (B) the closing bid price on the date of
delivery of such certificate and the other documents as specified in Clauses (i)
and (ii) of the paragraph immediately above.

                  (c) The Company will not object to and shall permit (except as
         prohibited by law) an Investor to pledge or grant a security interest
         in some or all of the Securities in connection with a bona fide margin
         agreement or other loan or financing arrangement secured by the
         Securities, and if required under the terms of such agreement, loan or
         arrangement, the Company will not object to and shall permit (except as
         prohibited by law) such Investor to transfer pledged or secured
         Securities to the pledges or secured parties. Except as required by
         law, such a pledge or transfer would not be subject to approval of the
         Company, no legal opinion of the pledgee, secured party or pledgor
         shall be required in connection therewith, and no notice shall be
         required of such pledge. Each Investor acknowledges that the Company

                                       20

<PAGE>

         shall not be responsible for any pledges relating to, or the grant of
         any security interest in, any of the Securities or for any agreement,
         understanding or arrangement between any Investor and its pledgee or
         secured party. At the appropriate Investor's expense, the Company will
         execute and deliver such reasonable documentation as a pledgee or
         secured party of Securities may reasonably request in connection with a
         pledge or transfer of the Securities, including the preparation and
         filing of any required prospectus supplement under Rule 424(b)(3) of
         the Securities Act or other applicable provision of the Securities Act
         to appropriately amend the list of Selling Stockholders thereunder.
         Provided that the Company is in compliance with the terms of this
         Section 4.1(c), the Company's indemnification obligations pursuant to
         Section 6.4 shall not extend to any Proceeding or Losses arising out of
         or related to this Section 4.1(c).

         4.2 FURNISHING OF INFORMATION. Until the date that any Investor owning
Shares or Warrant Shares may sell all of them under Rule 144(k) of the
Securities Act (or any successor provision), the Company shall timely file (or
obtain extensions in respect thereof and file within the applicable grace
period) all reports required to be filed by the Company after the date hereof
pursuant to the Exchange Act. The Company further covenants that it will take
such further action as any holder of Securities may reasonably request to
satisfy the provisions of this Section 4.2.

         4.3 INTEGRATION. The Company shall not, and shall use its commercially
reasonably efforts to ensure that no Affiliate thereof shall, sell, offer for
sale or solicit offers to buy or otherwise negotiate in respect of any security
(as defined in Section 2 of the Securities Act) that would be integrated with
the offer or sale of the Securities in a manner that would require the
registration under the Securities Act of the sale of the Securities to the
Investors or that would be integrated with the offer or sale of the Securities
for purposes of the rules and regulations of any Trading Market. The Company
further covenants that it shall not issue or register any additional shares of
Common Stock until after effectiveness of the Registration Statement other than
issuances and/or registrations in connection with (i) the exercise of
outstanding options and/or warrants, (ii) stock based compensation plans on Form
S-8, or (iii) acquisitions on Form S-4.

         4.4 ACKNOWLEDGEMENT REGARDING INVESTORS' TRADING ACTIVITY. Anything in
this Agreement or elsewhere herein to the contrary notwithstanding, but subject
to compliance by the Investors with applicable law, it is understood and
acknowledged by the Company (i) that none of the Investors have been asked to
agree, nor has any Investor agreed, to desist from purchasing or selling, long
and/or short, securities of the Company, or "derivative" securities based on
securities issued by the Company or to hold the Securities for any specified
term; (ii) that past or future open market or other transactions by any
Investor, including, without limitation, short sales or "derivative"
transactions, before or after the closing of this or future private placement
transactions, may negatively impact the market price of the Company's
publicly-traded securities; (iii) that any Investor, and counter parties in
"derivative" transactions to which any such Investor is a party, directly or
indirectly, presently may have a "short" position in the Common Stock, and (iv)
that each Investor shall not be deemed to have any affiliation with or control
over any arm's length counter-party in any "derivative" transaction. The Company
further understands and acknowledges that (a) one or more Investors may engage
in hedging activities at various times during the period that the Securities are

                                       21

<PAGE>

outstanding, (b) such hedging activities (if any) could reduce the value of the
existing stockholders' equity interests in the Company at and after the time
that the hedging activities are being conducted and (c) nothing contained herein
shall preclude any Investor from having taken or from taking any action in
respect of the identification of the availability of, or securing of, available
shares to borrow in order to effect short sales or similar transactions.

         4.5 RESERVATION OF SECURITIES. The Company shall maintain a reserve
from its duly authorized shares of Common Stock for issuance pursuant to the
Transaction Documents in such amount as may be required to fulfill its
obligations to issue such Shares under the Transaction Documents. In the event
that at any time the then authorized shares of Common Stock are insufficient for
the Company to satisfy its obligations to issue such Shares under the
Transaction Documents, the Company shall promptly take such actions as may be
required to increase the number of authorized shares.

         4.6 SECURITIES LAWS DISCLOSURE; PUBLICITY. The Company shall, on or
before 8:30 a.m., New York time, on the first Trading Day following execution of
this Agreement, issue a press release reasonably acceptable to the Investors
disclosing all material terms of the transactions contemplated hereby. On the
Closing Date, the Company shall file a Current Report on Form 8-K with the SEC
(the "8-K FILING") describing the terms of the transactions contemplated by the
Transaction Documents and including as exhibits to such Current Report on Form
8-K the Transaction Documents (including the schedules and the names, and
addresses of the Investors and the amount(s) of Securities respectively
purchased) and the form of Warrants, in the form required by the Exchange Act.
Thereafter, the Company shall timely file any filings and notices required by
the SEC or applicable law with respect to the transactions contemplated hereby
and provide copies thereof to the Investors promptly after filing. Except as
herein provided, the Company shall not publicly disclose the name of any
Investor, or include the name of any Investor in any press release without the
prior written consent of such Investor, unless otherwise required by law. The
Company shall not, and shall cause each of its Subsidiaries and its and each of
their respective officers, directors, employees and agents not to, provide any
Investor with any material nonpublic information regarding the Company or any of
its Subsidiaries from and after the issuance of the above referenced press
release without the express written consent of such Investor.

         4.7 USE OF PROCEEDS. The Company intends to use the net proceeds from
the sale of the Securities for working capital and general corporate purposes.
The Company also may use a portion of the net proceeds, currently intended for
general corporate purposes, to acquire or invest in technologies, products or
services that complement its business, although the Company has no present plans
or commitments and is not currently engaged in any material negotiations with
respect to these types of transactions. Pending these uses, the Company intends
to invest the net proceeds from this offering in short-term, interest-bearing,
investment-grade securities, or as otherwise pursuant to the Company's customary
investment policies.

                               REGISTRATION RIGHTS

         6.1  REGISTRATION STATEMENT.

                      (a) As promptly as possible, and in any event on or prior
     to the Filing Date, the Company shall prepare and file with the SEC a
     Registration Statement covering the resale of all Registrable Securities
     for an offering to be made on a continuous basis pursuant to Rule 415. The
     Registration Statement shall be on Form S-3 (except if the Company is not
     then eligible to register for resale the Registrable Securities on Form
     S-3, in which case such registration shall be on another appropriate form
     in accordance with the Securities Act and the Exchange Act) and shall
     contain (except if otherwise directed by the Investors or requested by the
     SEC) the "Plan of Distribution" in substantially the form attached hereto
     as EXHIBIT D.

                      (b) The Company shall use its commercially reasonable
     efforts to cause the Registration Statement to be declared effective by the
     SEC as promptly as possible after the filing thereof, but in any event
     prior to the Required Effectiveness Date, and shall use its commercially
     reasonable efforts to keep the Registration Statement continuously
     effective under the Securities Act until the earlier of the date that all
     Common Shares and Warrant Shares covered by such Registration Statement
     have been sold or can be sold publicly under Rule 144(k) (the
     "EFFECTIVENESS PERIOD"); PROVIDED THAT, upon notification by the SEC that a
     Registration Statement will not be reviewed or is no longer subject to
     further review and comments, the Company shall request acceleration of such
     Registration Statement within five (5) Trading Days after receipt of such
     notice and request that it becomes effective on 4:00 p.m. New York City
     time on the Effective Date and file a prospectus supplement for any
     Registration Statement, whether or not required under Rule 424 (or
     otherwise), by 9:00 a.m. New York City time the day after the Effective
     Date.

                      (c) The Company shall notify the Investors in writing
     promptly (and in any event within two Trading Days) after receiving
     notification from the SEC that the Registration Statement has been declared
     effective.

                      (d) Should an Event (as defined below) occur, then upon
     the occurrence of such Event, and on every monthly anniversary thereof
     until the applicable Event is cured, as partial relief for the damages
     suffered therefrom by the Investors (which remedy shall not be exclusive of
     any other remedies available under this Agreement, at law or in equity),
     the Company shall pay to each Investor an amount in cash, as liquidated
     damages and not as a penalty, equal to one percent (1.0%) of (i) the number
     of Common Shares held by such Investor as of the date of such Event,
     multiplied by (ii) the per share purchase price paid by such Investor for
     such Common Shares then held; PROVIDED, HOWEVER, that the total amount of
     payments pursuant to the Section 6.1(d) shall not exceed, when aggregated
     with all such payments paid to all Investors shall not exceed ten percent
     (10%) of the aggregate purchase price. The payments to which an Investor
     shall be entitled pursuant to this SECTION 6.1(D) are referred to herein as
     "EVENT PAYMENTS." Any Event Payments payable pursuant to the terms hereof
     shall apply on a pro rata basis for any portion of a month prior to the
     cure of an Event. In the event the Company fails to make Event Payments in

                                       24

<PAGE>

     a timely manner, such Event Payments shall bear interest at the rate of one
     percent (1.0%) per month (prorated for partial months) until paid in full.
     All pro rated calculations made pursuant to this paragraph shall be based
     upon the actual number of days in such pro rated month.

For such purposes, each of the following shall constitute an "Event":

                           (i) the Registration Statement is not filed on or
prior to the Filing Date or is not declared effective on or prior to the
Required Effectiveness Date;

                           (ii) except as provided for in SECTION 6.1(E) (the
"EXCLUDED EVENTS"), after the Effective Date, an Investor is not permitted to
sell Registrable Securities under the Registration Statement (or a subsequent
Registration Statement filed in replacement thereof) for any reason (other than
the fault of such Investor) for five or more Trading Days (whether or not
consecutive);

                           (iii) except as a result of the Excluded Events, the
Common Stock is not listed or quoted, or is suspended from trading, on an
Eligible Market for a period of three Trading Days (which need not be
consecutive Trading Days) during the Effectiveness Period;

                           (iv) with respect to an Investor, the Company fails
for any reason to deliver a certificate evidencing any Securities to such
Investor within five Trading Days after delivery of such certificate is required
pursuant to any Transaction Document or the exercise rights of the Investors
pursuant to the Warrants are otherwise suspended for any reason; or

                           (v) during the Effectiveness Period, except as a
result of the Excluded Events, the Company fails to have any Shares listed on an
Eligible Market.

                      (e) Notwithstanding anything in this Agreement to the
     contrary, after 60 consecutive Trading Days of continuous effectiveness of
     the initial Registration Statement filed and declared effective pursuant to
     this Agreement, the Company may, by written notice to the Investors,
     suspend sales under a Registration Statement after the Effective Date
     thereof and/or require that the Investors immediately cease the sale of
     shares of Common Stock pursuant thereto and/or defer the filing of any
     subsequent Registration Statement if the Company is engaged in a material
     merger, acquisition or sale and the Board of Directors determines in good
     faith, by appropriate resolutions, that, as a result of such activity, (A)
     it would be materially detrimental to the Company (other than as relating
     solely to the price of the Common Stock) to maintain a Registration
     Statement at such time or (B) it is in the best interests of the Company to
     suspend sales under such registration at such time. Upon receipt of such
     notice, each Investor shall immediately discontinue any sales of
     Registrable Securities pursuant to such registration until such Investor is
     advised in writing by the Company that the current Prospectus or amended
     Prospectus, as applicable, may be used. In no event, however, shall this
     right be exercised to suspend sales beyond the period during which (in the
     good faith determination of the Company's Board of Directors) the failure
     to require such suspension would be materially detrimental to the Company.
     The Company's rights under this SECTION 6(E) may be exercised for a period

                                       25

<PAGE>

     of no more than 10 Trading Days at a time and not more than three times in
     any twelve-month period, without such suspension being considered as part
     of an Event Payment determination. Immediately after the end of any
     suspension period under this SECTION 6(E), the Company shall take all
     necessary actions (including filing any required supplemental prospectus)
     to restore the effectiveness of the applicable Registration Statement and
     the ability of the Investors to publicly resell their Registrable
     Securities pursuant to such effective Registration Statement.

                      (f) The Company shall not, from the date hereof until the
     Effective Date of the Registration Statement, prepare and file with the SEC
     a registration statement relating to an offering for its own account or the
     account of others under the Securities Act of any of its equity securities,
     other than any registration statement or post-effective amendment to a
     registration statement (or supplement thereto) relating to the Company's
     employee benefit plans registered on Form S-8.

         6.2 REGISTRATION PROCEDURES. In connection with the Company's
registration obligations hereunder, the Company shall:

                      (a) Not less than three Trading Days prior to the filing
     of a Registration Statement or any related Prospectus or any amendment or
     supplement thereto, furnish via email to those Investors who have supplied
     the Company with email addresses copies of all such documents proposed to
     be filed, which documents (other than any document that is incorporated or
     deemed to be incorporated by reference therein) will be subject to the
     review of such Investors. The Company shall reflect in each such document
     when so filed with the SEC such comments regarding the Investors and the
     plan of distribution as the Investors may reasonably and promptly propose
     no later than two Trading Days after the Investors have been so furnished
     with copies of such documents as aforesaid.

                      (b) (i) Subject to SECTION 6.1(E), prepare and file with
     the SEC such amendments, including post-effective amendments, to each
     Registration Statement and the Prospectus used in connection therewith as
     may be necessary to keep the Registration Statement continuously effective,
     as to the applicable Registrable Securities for the Effectiveness Period
     and prepare and file with the SEC such additional Registration Statements
     in order to register for resale under the Securities Act all of the
     Registrable Securities; (ii) cause the related Prospectus to be amended or
     supplemented by any required Prospectus supplement, and as so supplemented
     or amended to be filed pursuant to Rule 424; (iii) respond as promptly as
     reasonably possible, and in any event within 12 Trading Days (except to the
     extent that the Company reasonably requires additional time to respond to
     accounting comments), to any comments received from the SEC with respect to
     the Registration Statement or any amendment thereto; and (iv) comply in all
     material respects with the provisions of the Securities Act and the
     Exchange Act with respect to the disposition of all Registrable Securities
     covered by the Registration Statement during the applicable period in
     accordance with the intended methods of disposition by the Investors
     thereof set forth in the Registration Statement as so amended or in such
     Prospectus as so supplemented.

                      (c) Notify the Investor as promptly as reasonably
     possible, and (if requested by the Investor confirm such notice in writing
     no later than one Trading Day thereafter, of any of the following events:

                                       26

<PAGE>

     (i) the SEC notifies the Company whether there will be a "review" of any
     Registration Statement; (ii) the SEC comments in writing on any
     Registration Statement; (iii) any Registration Statement or any
     post-effective amendment is declared effective; (iv) the SEC or any other
     Federal or state governmental authority requests any amendment or
     supplement to any Registration Statement or Prospectus or requests
     additional information related thereto; (v) the SEC issues any stop order
     suspending the effectiveness of any Registration Statement or initiates any
     Proceedings for that purpose; (vi) the Company receives notice of any
     suspension of the qualification or exemption from qualification of any
     Registrable Securities for sale in any jurisdiction, or the initiation or
     threat of any Proceeding for such purpose; or (vii) the financial
     statements included in any Registration Statement become ineligible for
     inclusion therein or any Registration Statement or Prospectus or other
     document contains any untrue statement of a material fact or omits to state
     any material fact required to be stated therein or necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading.

                      (d) Use its Best Efforts to avoid the issuance of or, if
     issued, obtain the withdrawal of (i) any order suspending the effectiveness
     of any Registration Statement, or (ii) any suspension of the qualification
     (or exemption from qualification) of any of the Registrable Securities for
     sale in any jurisdiction, as soon as possible.

                      (e) If requested by an Investor, provide such Investor,
     without charge, at least one conformed copy of each Registration Statement
     and each amendment thereto, including financial statements and schedules,
     and all exhibits to the extent requested by such Person (including those
     previously furnished or incorporated by reference) promptly after the
     filing of such documents with the SEC.

                      (f) Promptly deliver to each Investor, without charge, as
     many copies of the Prospectus or Prospectuses (including each form of
     prospectus) and each amendment or supplement thereto as such Persons may
     reasonably request. The Company hereby consents to the use of such
     Prospectus and each amendment or supplement thereto by each of the selling
     Investors in connection with the offering and sale of the Registrable
     Securities covered by such Prospectus and any amendment or supplement
     thereto to the extent permitted by federal and state securities laws and
     regulations.

                      (g) (i) In the time and manner required by each Trading
     Market, prepare and file with such Trading Market an additional shares
     listing application covering all of the Registrable Securities; (ii) take
     all steps necessary to cause such Common Shares to be approved for listing
     on each Trading Market as soon as possible thereafter; (iii) provide to
     Investor Counsel evidence of such listing; and (iv) except as a result of
     the Excluded Events, during the Effectiveness Period, maintain the listing
     of such Common Shares on each such Trading Market or another Eligible
     Market.

                      (h) Prior to any public offering of Registrable
     Securities, use its reasonable Best Efforts to register or qualify or
     cooperate with the selling Investors in connection with the registration or
     qualification (or exemption from such registration or qualification) of

                                       27

<PAGE>

     such Registrable Securities for offer and sale under the securities or Blue
     Sky laws of such jurisdictions within the United States as any Investor
     requests in writing, to keep each such registration or qualification (or
     exemption therefrom) effective for so long as required, but not to exceed
     the duration of the Effectiveness Period, and to do any and all other acts
     or things reasonably necessary or advisable to enable the disposition in
     such jurisdictions of the Registrable Securities covered by a Registration
     Statement; PROVIDED, HOWEVER, that the Company shall not be obligated to
     file any general consent to service of process or to qualify as a foreign
     corporation or as a dealer in securities in any jurisdiction in which it is
     not so qualified or to subject itself to taxation in respect of doing
     business in any jurisdiction in which it is not otherwise so subject.

                      (i) Cooperate with the Investors to facilitate the timely
     preparation and delivery of certificates representing Registrable
     Securities to be delivered to a transferee pursuant to a Registration
     Statement, which certificates shall be free, to the extent permitted by
     this Agreement and under law, of all restrictive legends, and to enable
     such Registrable Securities to be in such denominations and registered in
     such names as any such Investors may reasonably request.

                      (j) Upon the occurrence of any event described in SECTION
     6.2(C)(VII), as promptly as reasonably possible, prepare a supplement or
     amendment, including a post-effective amendment, to the Registration
     Statement or a supplement to the related Prospectus or any document
     incorporated or deemed to be incorporated therein by reference, and file
     any other required document so that, as thereafter delivered, neither the
     Registration Statement nor such Prospectus will contain an untrue statement
     of a material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading.

                      (k) Cooperate with any reasonable due diligence
     investigation undertaken by the Investors in connection with the sale of
     Registrable Securities, including, without limitation, by making available
     documents and information; provided that the Company will not deliver or
     make available to any Investor material, nonpublic information unless such
     Investor requests in advance in writing to receive material, nonpublic
     information and agrees to keep such information confidential.

                      (l) Comply with all rules and regulations of the SEC
     applicable to the registration of the Securities.

                      (m) It shall be a condition precedent to the obligations
     of the Company to complete the registration pursuant to this Agreement with
     respect to the Registrable Securities of any particular Investor or to make
     any Event Payments set forth in Section 6.1(c) to such Investor that such
     Investor furnish to the Company the information specified in Exhibits B-1,
     B-2 and B-3 hereto and such other information regarding itself, the
     Registrable Securities and other shares of Common Stock held by it and the
     intended method of disposition of the Registrable Securities held by it (if
     different from the Plan of Distribution set forth on Exhibit D hereto) as
     shall be reasonably required to effect and/or maintain the registration of
     such Registrable Securities and shall complete and execute such documents
     in connection with such registration as the Company may reasonably request.

                                       28

<PAGE>

                      (n) The Company shall comply with all applicable rules and
     regulations of the SEC under the Securities Act and the Exchange Act,
     including, without limitation, Rule 172 under the Securities Act, file any
     final Prospectus, including any supplement or amendment thereof, with the
     SEC pursuant to Rule 424 under the Securities Act, promptly inform the
     Holders in writing if, at any time during the Effectiveness Period, the
     Company does not satisfy the conditions specified in Rule 172 and, as a
     result thereof, the Holders are required to make available a Prospectus in
     connection with any disposition of Registrable Securities and take such
     other actions as may be reasonably necessary to facilitate the registration
     of the Registrable Securities hereunder.

         6.3 REGISTRATION EXPENSES. The Company shall pay all fees and expenses
incident to the performance of or compliance with Article VI of this Agreement
by the Company, including without limitation (a) all registration and filing
fees and expenses, including without limitation those related to filings with
the SEC, any Trading Market and in connection with applicable state securities
or Blue Sky laws, (b) printing expenses (including without limitation expenses
of printing certificates for Registrable Securities), (c) messenger, telephone
and delivery expenses, (d) fees and disbursements of counsel for the Company,
(e) fees and expenses of all other Persons retained by the Company in connection
with the consummation of the transactions contemplated by this Agreement, and
(f) all listing fees to be paid by the Company to the Trading Market.

         6.4  INDEMNIFICATION

                      (a) INDEMNIFICATION BY THE COMPANY. The Company shall,
     notwithstanding any termination of this Agreement, indemnify and hold
     harmless each Investor, the officers, directors, partners, members, agents
     and employees of each of them, each Person who controls any such Investor
     (within the meaning of Section 15 of the Securities Act or Section 20 of
     the Exchange Act) and the officers, directors, partners, members, agents
     and employees of each such controlling Person, to the fullest extent
     permitted by applicable law, from and against any and all Losses, as
     incurred, arising out of or relating to (i) any misrepresentation or breach
     of any representation or warranty made by the Company in the Transaction
     Documents or any other certificate, instrument or document contemplated
     hereby or thereby, (ii) any breach of any covenant, agreement or obligation
     of the Company contained in the Transaction Documents or any other
     certificate, instrument or document contemplated hereby or thereby, (iii)
     any cause of action, suit or claim brought or made against such Indemnified
     Party (as defined in Section 6.4(c) below) by a third party (including for
     these purposes a derivative action brought on behalf of the Company),
     arising out of or resulting from (x) execution, delivery, performance or
     enforcement of the Transaction Documents or any other certificate,
     instrument or document contemplated hereby or thereby, (y) any transaction
     financed or to be financed in whole or in part, directly or indirectly,
     with the proceeds of the issuance of the Securities, or (z) the status of
     Indemnified Party as holder of the Securities or (iv) any untrue or alleged
     untrue statement of a material fact contained in the Registration
     Statement, any Prospectus or any form of Company prospectus or in any

                                       29

<PAGE>

     amendment or supplement thereto or in any Company preliminary prospectus,
     or arising out of or relating to any omission or alleged omission of a
     material fact required to be stated therein or necessary to make the
     statements therein (in the case of any Prospectus or form of prospectus or
     supplement thereto, in the light of the circumstances under which they were
     made) not misleading, except to the extent, but only to the extent, that
     (A) such untrue statements, alleged untrue statements, omissions or alleged
     omissions are based solely upon information regarding such Investor
     furnished in writing to the Company by such Investor for use therein, or to
     the extent that such information relates to such Investor or such
     Investor's proposed method of distribution of Registrable Securities and
     was reviewed and expressly approved by such Investor expressly for use in
     the Registration Statement, or (B) with respect to any prospectus, if the
     untrue statement or omission of material fact contained in such prospectus
     was corrected on a timely basis in the prospectus, as then amended or
     supplemented, if such corrected prospectus was timely made available by the
     Company to the Holder, and the Holder seeking indemnity hereunder was
     advised in writing not to use the incorrect prospectus prior to the use
     giving rise to Losses.

                      (b) INDEMNIFICATION BY INVESTORS. Each Investor shall,
     severally and not jointly, indemnify and hold harmless the Company, its
     directors, officers, agents and employees, each Person who controls the
     Company (within the meaning of SECTION 15 of the Securities Act and SECTION
     20 of the Exchange Act), and the directors, officers, agents or employees
     of such controlling Persons, to the fullest extent permitted by applicable
     law, from and against all Losses (as determined by a court of competent
     jurisdiction in a final judgment not subject to appeal or review) arising
     solely out of any untrue statement of a material fact contained in the
     Registration Statement, any Prospectus, or any form of prospectus, or in
     any amendment or supplement thereto, or arising out of or relating to any
     omission of a material fact required to be stated therein or necessary to
     make the statements therein (in the case of any Prospectus or form of
     prospectus or supplement thereto, in the light of the circumstances under
     which they were made) not misleading, but only to the extent that such
     untrue statement or omission is contained in any information so furnished
     by such Investor in writing to the Company specifically for inclusion in
     such Registration Statement or such Prospectus or to the extent that such
     untrue statements or omissions are based solely upon information regarding
     such Investor furnished to the Company by such Investor in writing
     expressly for use therein, or to the extent that such information relates
     to such Investor or such Investor's proposed method of distribution of
     Registrable Securities and was reviewed and expressly approved by such
     Investor expressly for use in the Registration Statement (it being
     understood that the information provided by the Investor to the Company in
     Exhibits B-1, B-2 and B-3 and the Plan of Distribution set forth on Exhibit
     D, as the same may be modified by such Investor and other information
     provided by the Investor to the Company in or pursuant to the Transaction
     Documents constitutes information reviewed and expressly approved by such
     Investor in writing expressly for use in the Registration Statement), such
     Prospectus or such form of Prospectus or in any amendment or supplement
     thereto. In no event shall the liability of any selling Investor hereunder
     be greater in amount than the dollar amount of the net proceeds received by
     such Investor upon the sale of the Registrable Securities giving rise to
     such indemnification obligation.

                                       30

<PAGE>

                      (c) CONDUCT OF INDEMNIFICATION PROCEEDINGS. If any
     Proceeding shall be brought or asserted against any Person entitled to
     indemnity hereunder (an "INDEMNIFIED PARTY"), such Indemnified Party shall
     promptly notify the Person from whom indemnity is sought (the "INDEMNIFYING
     PARTY") in writing, and the Indemnifying Party shall assume the defense
     thereof, including the employment of counsel reasonably satisfactory to the
     Indemnified Party and the payment of all fees and expenses incurred in
     connection with defense thereof; provided, that the failure of any
     Indemnified Party to give such notice shall not relieve the Indemnifying
     Party of its obligations or liabilities pursuant to this Agreement, except
     (and only) to the extent that it shall be finally determined by a court of
     competent jurisdiction (which determination is not subject to appeal or
     further review) that such failure shall have proximately and materially
     adversely prejudiced the Indemnifying Party.

         An Indemnified Party shall have the right to employ separate counsel in
any such Proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party or
Parties unless: (i) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (ii) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (iii) the
named parties to any such Proceeding (including any impleaded parties) include
both such Indemnified Party and the Indemnifying Party, and such Indemnified
Party shall have been advised by counsel that a conflict of interest is likely
to exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and the reasonable fees and expenses of
separate counsel shall be at the expense of the Indemnifying Party). It being
understood, however, that the Indemnifying Party shall not, in connection with
any one such Proceeding (including separate Proceedings that have been or will
be consolidated before a single judge) be liable for the fees and expenses of
more than one separate firm of attorneys at any time for all Indemnified
Parties, which firm shall be appointed by a majority of the Indemnified Parties.
The Indemnifying Party shall not be liable for any settlement of any such
Proceeding effected without its written consent, which consent shall not be
unreasonably withheld. No Indemnifying Party shall, without the prior written
consent of the Indemnified Party, effect any settlement of any pending
Proceeding in respect of which any Indemnified Party is a party, unless such
settlement includes an unconditional release of such Indemnified Party from all
liability on claims that are the subject matter of such Proceeding.

         All reasonable fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such Proceeding in a manner not
inconsistent with this Section) shall be paid to the Indemnified Party, as
incurred, within 20 Trading Days of written notice thereof to the Indemnifying
Party (regardless of whether it is ultimately determined that an Indemnified
Party is not entitled to indemnification hereunder; provided, that the
Indemnifying Party may require such Indemnified Party to undertake to reimburse
all such fees and expenses to the extent it is finally judicially determined
that such Indemnified Party is not entitled to indemnification hereunder).

                                       31

<PAGE>

                      (d) CONTRIBUTION. If a claim for indemnification under
     SECTION 6.4(A) or (B) is unavailable to an Indemnified Party (by reason of
     public policy or otherwise), then each 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, in such
     proportion as is appropriate to reflect the relative fault of the
     Indemnifying Party and Indemnified Party in connection with the actions,
     statements or omissions that resulted in such Losses as well as any other
     relevant equitable considerations. The relative fault of such Indemnifying
     Party and Indemnified Party shall be determined by reference to, among
     other things, whether any action in question, including any untrue or
     alleged untrue statement of a material fact or omission or alleged omission
     of a material fact, has been taken or made by, or relates to information
     supplied by, such Indemnifying Party or Indemnified Party, and the parties'
     relative intent, knowledge, access to information and opportunity to
     correct or prevent such action, statement or omission. The amount paid or
     payable by a party as a result of any Losses shall be deemed to include,
     subject to the limitations set forth in SECTION 6.4(C), any reasonable
     attorneys' or other reasonable fees or expenses incurred by such party in
     connection with any Proceeding to the extent such party would have been
     indemnified for such fees or expenses if the indemnification provided for
     in this Section was available to such party in accordance with its terms.

         The parties hereto agree that it would not be just and equitable if
contribution pursuant to this SECTION 6.4(D) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this SECTION 6.4(D), no Investor shall be
required to contribute, in the aggregate, any amount in excess of the amount by
which the proceeds actually received by such Investor from the sale of the
Registrable Securities subject to the Proceeding exceeds the amount of any
damages that such Investor has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No Person
guilty of fraudulent misrepresentation (within the meaning of SECTION 11(F) of
the Securities Act) shall be entitled to contribution from any Person who was
not guilty of such fraudulent misrepresentation.

         The indemnity and contribution agreements contained in this Section are
in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

         6.5 DISPOSITIONS. Each Investor agrees that it will comply with the
prospectus delivery requirements of the Securities Act as applicable to it in
connection with sales of Registrable Securities pursuant to the Registration
Statement and shall sell its Registrable Securities in accordance with the Plan
of Distribution set forth in the Prospectus. Each Investor further agrees that,
upon receipt of a notice from the Company of the occurrence of any event of the
kind described in SECTIONS 6.2(C)(V), (VI) or (VII), such Investor will
discontinue disposition of such Registrable Securities under the Registration
Statement until such Investor is advised in writing by the Company that the use
of the Prospectus, or amended Prospectus, as necessary, may be used. The Company
may provide appropriate stop orders to enforce the provisions of this paragraph.

         6.6 NO PIGGYBACK ON REGISTRATIONS. Neither the Company nor any of its
security holders (other than the Investors in such capacity pursuant hereto) may
include securities of the Company in the Registration Statement other than the
Registrable Securities.

         6.7 PIGGY-BACK REGISTRATIONS. If at any time during the Effectiveness
Period there is not an effective Registration Statement covering all of the
Registrable Securities and the Company shall determine to prepare and file with
the SEC a registration statement relating to an offering for its own account or
the account of others under the Securities Act of any of its equity securities,
other than on Form S-4 or Form S-8 (each as promulgated under the Securities
Act) or their then equivalents relating to equity securities to be issued solely
in connection with any acquisition of any entity or business or equity
securities issuable in connection with stock option or other employee benefit
plans, then the Company shall send to each Investor not then eligible to sell
all of their Registrable Securities under Rule 144 in a three-month period,
written notice of such determination and if, within ten days after receipt of
such notice, any such Investor shall so request in writing, the Company shall
include in such registration statement all or any part of such Registrable
Securities such Investor requests to be registered. Notwithstanding the
foregoing, in the event that, in connection with any underwritten public
offering, the managing underwriter(s) thereof shall impose a limitation on the
number of shares of Common Stock which may be included in the Registration
Statement because, in such underwriter(s)' judgment, marketing or other factors
dictate such limitation is necessary to facilitate public distribution, then the
Company shall be obligated to include in such Registration Statement only such
limited portion of the Registrable Securities with respect to which such
Investor has requested inclusion hereunder as the underwriter shall permit;
PROVIDED, HOWEVER, that (i) the Company shall not exclude any Registrable
Securities unless the Company has first excluded all outstanding securities, the
holders of which are not contractually entitled to inclusion of such securities
in such Registration Statement or are not contractually entitled to pro rata
inclusion with the Registrable Securities and (ii) after giving effect to the
immediately preceding proviso, any such exclusion of Registrable Securities
shall be made pro rata among the Investors seeking to include Registrable
Securities and the holders of other securities having the contractual right to
inclusion of their securities in such Registration Statement by reason of demand
registration rights, in proportion to the number of Registrable Securities or
other securities, as applicable, sought to be included by each such Investor or
other holder. If an offering in connection with which an Investor is entitled to
registration under this Section 6.7 is an underwritten offering, then each
Investor whose Registrable Securities are included in such Registration
Statement shall, unless otherwise agreed by the Company, offer and sell such
Registrable Securities in an underwritten offering using the same underwriter or
underwriters and, subject to the provisions of this Agreement, on the same terms
and conditions as other shares of Common Stock included in such underwritten
offering and shall enter into an underwriting agreement in a form and substance
reasonably satisfactory to the Company and the underwriter or underwriters. Upon
the effectiveness the registration statement for which piggy-back registration
has been provided in this Section 6.7, any Event Payments payable to an Investor
whose Securities are included in such registration statement shall terminate.

                                   ARTICLE VII
                                  MISCELLANEOUS

         7.1 TERMINATION. This Agreement may be terminated by the Company or any
Investor, by written notice to the other parties, if the Closing has not been
consummated by the third Business Day following the date of this Agreement;
provided that no such termination will affect the right of any party to sue for
any breach by the other party (or parties).

         7.2 FEES AND EXPENSES. Except as expressly set forth in the Transaction
Documents to the contrary, each party shall pay the fees and expenses of its
advisers, counsel, accountants and other experts, if any, and all other expenses
incurred by such party incident to the negotiation, preparation, execution,
delivery and performance of this Agreement. The Company shall pay all Transfer
Agent fees, stamp taxes and other taxes and duties levied in connection with the
sale and issuance of their applicable Securities.

         7.3 ENTIRE AGREEMENT. The Transaction Documents, together with the
Exhibits and Schedules thereto, contain the entire understanding of the parties
with respect to the subject matter hereof and supersede all prior agreements and
understandings, oral or written, with respect to such matters, which the parties
acknowledge have been merged into such documents, exhibits and schedules. At or
after the Closing, and without further consideration, the Company will execute
and deliver to the Investors such further documents as may be reasonably
requested in order to give practical effect to the intention of the parties
under the Transaction Documents.

         7.4 NOTICES. Any and all notices or other communications or deliveries
required or permitted to be provided hereunder shall be in writing and shall be
deemed given and effective on the earliest of (a) the date of transmission, if

as may be designated in writing hereafter, in the same manner, by any such
Person.

         7.5 AMENDMENTS; WAIVERS. No provision of this Agreement may be waived
or amended except in a written instrument signed, in the case of an amendment,
by the Company and each of the Investors or, in the case of a waiver, by the
party against whom enforcement of any such waiver is sought. No waiver of any
default with respect to any provision, condition or requirement of this
Agreement shall be deemed to be a continuing waiver in the future or a waiver of
any subsequent default or a waiver of any other provision, condition or
requirement hereof, nor shall any delay or omission of either party to exercise
any right hereunder in any manner impair the exercise of any such right.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of
Investors under ARTICLE VI may be given by Investors holding at least a majority
of the Registrable Securities to which such waiver or consent relates.

         7.6 CONSTRUCTION. The headings herein are for convenience only, do not
constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof. The language used in this Agreement will be deemed
to be the language chosen by the parties to express their mutual intent, and no
rules of strict construction will be applied against any party.

         7.7 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and
inure to the benefit of the parties and their successors and permitted assigns.
The Company may not assign this Agreement or any rights or obligations hereunder
without the prior written consent of the Investors. Any Investor may assign its
rights under this Agreement to any Person to whom such Investor assigns or
transfers any Securities, provided (i) such transferor agrees in writing with
the transferee or assignee to assign such rights, and a copy of such agreement
is furnished to the Company after such assignment, (ii) the Company is furnished
with written notice of (x) the name and address of such transferee or assignee
and (y) the Registrable Securities with respect to which such registration
rights are being transferred or assigned, (iii) following such transfer or
assignment, the further disposition of such securities by the transferee or
assignee is restricted under the Securities Act and applicable state securities
laws, (iv) such transferee agrees in writing to be bound, with respect to the
transferred Securities, by the provisions hereof that apply to the "Investors"
and (v) such transfer shall have been made in accordance with the applicable
requirements of this Agreement and with all laws applicable thereto.

         7.8 NO THIRD-PARTY BENEFICIARIES. This Agreement is intended for the
benefit of the parties hereto and their respective successors and permitted
assigns and is not for the benefit of, nor may any provision hereof be enforced
by, any other Person, except that each Indemnified Party is an intended third
party beneficiary of SECTION 6.4 and (in each case) may enforce the provisions
of such Sections directly against the parties with obligations thereunder.

         7.9 GOVERNING LAW; VENUE; WAIVER OF JURY TRIAL. THE CORPORATE LAWS OF
THE STATE OF DELAWARE SHALL GOVERN ALL ISSUES CONCERNING THE RELATIVE RIGHTS OF
THE COMPANY AND ITS STOCKHOLDERS. ALL QUESTIONS CONCERNING THE CONSTRUCTION,
VALIDITY, ENFORCEMENT AND INTERPRETATION OF THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. THE COMPANY
AND INVESTORS HEREBY IRREVOCABLY SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF THE
STATE AND FEDERAL COURTS SITTING IN THE CITY OF NEW YORK, BOROUGH OF MANHATTAN
FOR THE ADJUDICATION OF ANY DISPUTE BROUGHT BY THE COMPANY OR ANY INVESTOR
HEREUNDER, IN CONNECTION HEREWITH OR WITH ANY TRANSACTION CONTEMPLATED HEREBY OR
DISCUSSED HEREIN (INCLUDING WITH RESPECT TO THE ENFORCEMENT OF ANY OF THE
TRANSACTION DOCUMENTS), AND HEREBY IRREVOCABLY WAIVE, AND AGREE NOT TO ASSERT IN
ANY SUIT, ACTION OR PROCEEDING BROUGHT BY THE COMPANY OR ANY INVESTOR, ANY CLAIM
THAT IT IS NOT PERSONALLY SUBJECT TO THE JURISDICTION OF ANY SUCH COURT, OR THAT

                                       35

<PAGE>

SUCH SUIT, ACTION OR PROCEEDING IS IMPROPER. EACH PARTY HEREBY IRREVOCABLY
WAIVES PERSONAL SERVICE OF PROCESS AND CONSENTS TO PROCESS BEING SERVED IN ANY
SUCH SUIT, ACTION OR PROCEEDING BY MAILING A COPY THEREOF VIA REGISTERED OR
CERTIFIED MAIL OR OVERNIGHT DELIVERY (WITH EVIDENCE OF DELIVERY) TO SUCH PARTY
AT THE ADDRESS IN EFFECT FOR NOTICES TO IT UNDER THIS AGREEMENT AND AGREES THAT
SUCH SERVICE SHALL CONSTITUTE GOOD AND SUFFICIENT SERVICE OF PROCESS AND NOTICE
THEREOF. NOTHING CONTAINED HEREIN SHALL BE DEEMED TO LIMIT IN ANY WAY ANY RIGHT
TO SERVE PROCESS IN ANY MANNER PERMITTED BY LAW. THE COMPANY AND INVESTORS
HEREBY WAIVE ALL RIGHTS TO A TRIAL BY JURY.

         7.10 SURVIVAL. The representations and warranties, agreements and
covenants contained herein shall survive the Closing.

         7.11 EXECUTION. This Agreement may be executed in two or more
counterparts, all of which when taken together shall be considered one and the
same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party, it being understood that both
parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission or email attachment, such signature shall
create a valid and binding obligation of the party executing (or on whose behalf
such signature is executed) with the same force and effect as if such facsimile
or email-attached signature page were an original thereof.

         7.12 SEVERABILITY. If any provision of this Agreement is held to be
invalid or unenforceable in any respect, the validity and enforceability of the
remaining terms and provisions of this Agreement shall not in any way be
affected or impaired thereby and the parties will attempt to agree upon a valid
and enforceable provision that is a reasonable substitute therefor, and upon so
agreeing, shall incorporate such substitute provision in this Agreement.

         7.13 RESCISSION AND WITHDRAWAL RIGHT. Notwithstanding anything to the
contrary contained in (and without limiting any similar provisions of) the
Transaction Documents, whenever any Investor exercises a right, election, demand
or option owed to such Investor by the Company under a Transaction Document and
the Company does not timely perform its related obligations within the periods
therein provided, then, prior to the performance by the Company of the Company's
related obligation, such Investor may rescind or withdraw, in its sole
discretion from time to time upon written notice to the Company, any relevant
notice, demand or election in whole or in part without prejudice to its future
actions and rights.

         7.14 REPLACEMENT OF SECURITIES. If any certificate or instrument
evidencing any Securities is mutilated, lost, stolen or destroyed, the Company
shall issue or cause to be issued in exchange and substitution for and upon
cancellation thereof, or in lieu of and substitution therefor, a new certificate
or instrument, but only upon receipt of evidence reasonably satisfactory to the
Company of such loss, theft or destruction and the execution by the holder
thereof of a customary lost certificate affidavit of that fact and an agreement
to indemnify and hold harmless the Company for any losses in connection

                                       36

<PAGE>

therewith. The applicants for a new certificate or instrument under such
circumstances shall also pay any reasonable third-party costs associated with
the issuance of such replacement Securities.

         7.15 REMEDIES. In addition to being entitled to exercise all rights
provided herein or granted by law, including recovery of damages, each of the
Investors and the Company will be entitled to seek specific performance under
the Transaction Documents. The parties agree that monetary damages may not be
adequate compensation for any loss incurred by reason of any breach of
obligations described in the foregoing sentence and hereby agrees to waive in
any action for specific performance of any such obligation (other than in
connection with any action for temporary restraining order) the defense that a
remedy at law would be adequate.

         7.16 PAYMENT SET ASIDE. To the extent that the Company makes a payment
or payments to any Investor hereunder or any Investor enforces or exercises its
rights hereunder or thereunder, and such payment or payments or the proceeds of
such enforcement or exercise or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside, recovered from, disgorged
by or are required to be refunded, repaid or otherwise restored to the Company
by a trustee, receiver or any other person under any law (including, without
limitation, any bankruptcy law, state or federal law, common law or equitable
cause of action), then to the extent of any such restoration the obligation or
part thereof originally intended to be satisfied shall be revived and continued
in full force and effect as if such payment had not been made or such
enforcement or setoff had not occurred.

         7.17 ADJUSTMENTS IN SHARE NUMBERS AND PRICES. In the event of any stock
split, subdivision, dividend or distribution payable in shares of Common Stock
(or other securities or rights convertible into, or entitling the holder thereof
to receive directly or indirectly shares of Common Stock), combination or other
similar recapitalization or event occurring after the date hereof and prior to
the Closing, each reference in any Transaction Document to a number of shares or
a price per share shall be amended to appropriately account for such event.

         7.18 INDEPENDENT NATURE OF INVESTORS' OBLIGATIONS AND RIGHTS. The
obligations of each Investor under any Transaction Document are several and not
joint with the obligations of any other Investor, and no Investor shall be
responsible in any way for the performance of the obligations of any other
Investor under any Transaction Document. The decision of each Investor to
purchase Securities pursuant to this Agreement has been made by such Investor
independently of any other Investor and independently of any information,
materials, statements or opinions as to the business, affairs, operations,
assets, properties, liabilities, results of operations, condition (financial or
otherwise) or prospects of the Company which may have been made or given by any
other Investor or by any agent or employee of any other Investor, and no
Investor or any of its agents or employees shall have any liability to any other
Investor (or any other person) relating to or arising from any such information,
materials, statements or opinions. Nothing contained herein or in any
Transaction Document, and no action taken by any Investor pursuant thereto,
shall be deemed to constitute the Investors as a partnership, an association, a
joint venture or any other kind of entity, or create a presumption that the
Investors are in any way acting in concert or as a group with respect to such
obligations or the transactions contemplated by the Transaction Document. Each
Investor acknowledges that no other Investor has acted as agent for such
Investor in connection with making its investment hereunder and that no other
Investor will be acting as agent of such Investor in connection with monitoring

                                       37

<PAGE>

its investment hereunder. Each Investor shall be entitled to independently
protect and enforce its rights, including without limitation the rights arising
out of this Agreement or out of the other Transaction Documents, and it shall
not be necessary for any other Investor to be joined as an additional party in
any proceeding for such purpose.

                      OPINION OF COMPANY CORPORATE COUNSEL
                      ------------------------------------

Capitalized terms not defined herein shall have the meaning given them in the
Agreement.

1.       The Company is duly incorporated, validly existing and in good standing
         under the laws of the State of Delaware, with all the requisite power
         and authority to own, lease and operate its properties and to carry on
         its business as now being conducted.

2.       The Company has all requisite power and authority to execute, deliver,
         and perform its obligations under the Agreement. The execution and
         delivery of the Agreement by the Company and the performance of each of
         its obligations thereunder have been duly and validly authorized by all
         necessary corporate action and no further consent or authorization of
         the Company, its Board of Directors or its stockholders is required.

3.       Neither the execution, delivery or performance of the Agreement by the
         Company nor the consummation of the transactions contemplated thereby
         will (i) conflict with or violate the Company's Certificate of
         Incorporation or Bylaws, as each are currently in effect, (ii) conflict
         with or violate any law applicable to the Company, or by which any
         property or asset of any of the Company is bound or affected or (iii)
         result in a default under the terms of any agreement to which the
         Company is a party and which the Company has attached as an exhibit to
         its reports filed with the SEC under the Exchange Act.

4.       No approvals or authorizations by, or filings or qualifications with,
         any governmental authority or body are required in connection with the
         execution and delivery of the Agreement or any other agreements or
         documents executed and delivered pursuant thereto by the Company,
         except such as have been duly obtained or made.

5.       The shares of Common Stock issued by the Company under the Agreement
         (the "Shares") and the shares of Common Stock to be issued upon
         exercise of the Warrants issued under the Agreement (the "Warrant
         Shares") shall, when issued pursuant to the terms and conditions
         specified in the Agreement, and when paid for in accordance with their
         terms, be duly authorized, validly issued, fully paid and
         non-assessable shares. The Warrants shall, when issued pursuant to the
         terms and conditions specified in the Agreement, be duly authorized,
         validly issued and non-assessable and the Warrant Shares have been duly
         reserved for issuance by the Company.

6.       The Agreement and the Warrant have been duly executed and delivered by
         the Company and each constitutes a legal, valid and binding agreement
         of the Company enforceable against the Company in accordance with their
         respective terms, except as the enforceability thereof may be limited
         by bankruptcy, insolvency, reorganization, moratorium, or other similar

<PAGE>

         laws affecting the enforcement of creditors' rights generally and other
         general principles of equity and subject to other standard exceptions
         and qualifications. To our knowledge, neither the Shares nor the
         Warrant Shares are subject to any preemptive rights under the Company's
         Certificate of Incorporation or Bylaws.

7.       To our knowledge, there is no action, suit, claim, investigation or
         proceeding pending or threatened against the Company which questions
         the validity of the Agreement or the transactions contemplated thereby
         or any action taken or to be taken pursuant thereto.

8.       Subject to the accuracy of the representations and warranties of the
         parties to this Agreement and each of the Investors in the Offering and
         assuming that there has been no general solicitation or advertising of
         the Shares or Warrants to be sold under the Agreement, the offer,
         issuance and sale of the Shares, the Warrants and the Warrant Shares to
         the Investors pursuant to the Agreement, and in the case of the Warrant
         Shares, pursuant to the Warrants, are exempt from the registration
         requirements of the Securities Act.

                              PLAN OF DISTRIBUTION
                              --------------------

The selling stockholders may, from time to time, sell any or all of their shares
of common stock on any stock exchange, market or trading facility on which the
shares are traded or in private transactions. These sales may be at fixed or
negotiated prices. The selling stockholders may use any one or more of the
following methods when selling shares:

o        ordinary brokerage transactions and transactions in which the
         broker-dealer solicits purchasers;

o        block trades in which the broker-dealer will attempt to sell the shares
         as agent but may position and resell a portion of the block as
         principal to facilitate the transaction;

o        purchases by a broker-dealer as principal and resale by the
         broker-dealer for its account;

o        an exchange distribution in accordance with the rules of the applicable
         exchange;

o        privately negotiated transactions;

o        short sales;

o        broker-dealers may agree with the selling stockholders to sell a
         specified number of such shares at a stipulated price per share;

o        a combination of any such methods of sale; and

o        any other method permitted pursuant to applicable law.

         The selling stockholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

         Broker-dealers engaged by the selling stockholders may arrange for
other brokers-dealers to participate in sales. Broker-dealers may receive
commissions or discounts from the selling stockholders (or, if any broker-dealer
acts as agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated. The selling stockholders do not expect these commissions and
discounts to exceed what is customary in the types of transactions involved. Any
profits on the resale of shares of common stock by a broker-dealer acting as
principal might be deemed to be underwriting discounts or commissions under the
Securities Act. Discounts, concessions, commissions and similar selling
expenses, if any, attributable to the sale of shares will be borne by a selling
stockholder. The selling stockholders may agree to indemnify any agent, dealer
or broker-dealer that participates in transactions involving sales of the shares
if liabilities are imposed on that person under the Securities Act.

<PAGE>

         The selling stockholders may from time to time pledge or grant a
security interest in some or all of the shares of common stock owned by them
and, if they default in the performance of their secured obligations, the
pledgees or secured parties may offer and sell the shares of common stock from
time to time under this prospectus after we have filed a supplement to this
prospectus under Rule 424(b)(3) or other applicable provision of the Securities
Act of 1933 supplementing or amending the list of selling stockholders to
include the pledgee, transferee or other successors in interest as selling
stockholders under this prospectus.

         The selling stockholders also may transfer the shares of common stock
in other circumstances, in which case the transferees, pledgees or other
successors in interest will be the selling beneficial owners for purposes of
this prospectus and may sell the shares of common stock from time to time under
this prospectus after we have filed a supplement to this prospectus under Rule
424(b)(3) or other applicable provision of the Securities Act of 1933
supplementing or amending the list of selling stockholders to include the
pledgee, transferee or other successors in interest as selling stockholders
under this prospectus.

         The selling stockholders and any broker-dealers or agents that are
involved in selling the shares of common stock may be deemed to be
"underwriters" within the meaning of the Securities Act in connection with such
sales. In such event, any commissions received by such broker-dealers or agents
and any profit on the resale of the shares of common stock purchased by them may
be deemed to be underwriting commissions or discounts under the Securities Act.

         We are required to pay all fees and expenses incident to the
registration of the shares of common stock. We have agreed to indemnify the
selling stockholders against certain losses, claims, damages and liabilities,
including liabilities under the Securities Act.

         The selling stockholders have advised us that they have not entered
into any agreements, understandings or arrangements with any underwriters or
broker-dealers regarding the sale of their shares of common stock, nor is there
an underwriter or coordinating broker acting in connection with a proposed sale
of shares of common stock by any selling stockholder. If we are notified by any
selling stockholder that any material arrangement has been entered into with a
broker-dealer for the sale of shares of common stock, if required, we will file
a supplement to this prospectus. If the selling stockholders use this prospectus
for any sale of the shares of common stock, they will be subject to the
prospectus delivery requirements of the Securities Act.

         The anti-manipulation rules of Regulation M under the Securities
Exchange Act of 1934 may apply to sales of our common stock and activities of
the selling stockholders.

Company is issuing to the Holders shares (the "COMMON SHARES") of Common Stock
of the Company, par value $0.001 per share (the "COMMON Stock"), and Warrants
(the "WARRANTS"), which are exercisable into shares of Common Stock.

         This letter shall serve as our irrevocable authorization and direction
to you (provided that you are the transfer agent of the Company at such time):

         (i) to issue shares of Common Stock upon transfer or resale of the
Common Shares; and

         (ii) to issue shares of Common Stock upon the exercise of the Warrants
(the "WARRANT SHARES") to or upon the order of a Holder from time to time upon
delivery to you of a properly completed and duly executed Exercise Notice, in
the form attached hereto as EXHIBIT I, which has been acknowledged by the
Company as indicated by the signature of a duly authorized officer of the
Company thereon.

         You acknowledge and agree that so long as you have previously received
(a) written confirmation from the Company's legal counsel that either (i) a
registration statement covering resales of the Common Shares and the Warrant
Shares has been declared effective by the Securities and Exchange Commission
(the "SEC") under the Securities Act of 1933, as amended (the "1933 ACT") and
that resales of the Common Shares and the Warrant Shares may be made thereunder,
or (ii) sales of the Common Shares and the Warrant Shares may be made in
conformity with Rule 144 under the 1933 Act ("RULE 144"), (b) if applicable, a
copy of such registration statement, and (c) notice from legal counsel to the
Company or any Holder that a transfer of Common Shares and/or Warrant Shares has
been effected either pursuant to the registration statement (and a prospectus
delivered to the transferee) or pursuant to Rule 144, then, unless otherwise
required by law, within three (3) business days of your receipt of the notice
referred to in (c), you shall issue the certificates representing the Common
Shares and the Warrant Shares so sold to the transferees registered in the names

<PAGE>

of such transferees, and such certificates shall not bear any legend restricting
transfer of the Common Shares and the Warrant Shares thereby and should not be
subject to any stop-transfer restriction.

         A form of written confirmation (to be used in connection with any sale)
from the Company's outside legal counsel that a registration statement covering
resales of the Common Shares and the Warrant Shares has been declared effective
by the SEC under the 1933 Act is attached hereto as EXHIBIT II.

         Please be advised that the Holders are relying upon this letter as an
inducement to enter into the Agreement and, accordingly, each Holder is a third
party beneficiary to these instructions.

         Please execute this letter in the space indicated to acknowledge your
agreement to act in accordance with these instructions. Should you have any
questions concerning this matter, please contact me at (559) 435-1771.

2. The Certificate of Designations, Powers, Preferences and Rights of the Series
A Cumulative Redeemable Convertible Preferred Stock (the "CERTIFICATE OF
DESIGNATIONS") of the Company filed with the Delaware Secretary of State on
April 12, 2006, contains certain conversion price adjustment and preemptive
rights provisions in favor of the holders of the Series A Cumulative Redeemable
Convertible Preferred Stock (the "SERIES A PREFERRED STOCK").

--------------------
(1) The holders of the Series A Preferred Stock have conversion rights initially
equivalent to two shares of common stock for each share of Series A Preferred
Stock. The conversion ratio is subject to customary anti-dilution adjustments.
In addition, anti-dilution adjustments are to occur in the event that the
Company issues equity securities at a price equivalent to less than $8.00 per
share, including derivative securities convertible into equity securities (on an
as-converted or as-exercised basis). Certain specified issuances will not result
in anti-dilution adjustments. The shares of Series A Preferred Stock are also
subject to forced conversion upon the occurrence of a transaction that would
result in an internal rate of return to the holders of the Series A Preferred
Stock of 25% or more. Accrued but unpaid dividends on the Series A Preferred
Stock are to be paid in cash upon any conversion of the Series A Preferred
Stock.

                                   LITIGATION

         BARRY SPIEGEL

         On December 23, 2005, Barry J. Spiegel, a stockholder of Pacific
Ethanol and former director of Accessity, filed a complaint in the Circuit Court
of the 17th Judicial District in and for Broward County, Florida (Case No.
05018512), or the Spiegel Action, against Barry Siegel, Philip Kart, Kenneth
Friedman and Bruce Udell, or collectively, the Defendants. Messrs. Siegel, Udell
and Friedman are former directors of Accessity and Pacific Ethanol. Mr. Kart is
a former executive officer of Accessity and Pacific Ethanol.

         The Spiegel Action relates to the Share Exchange Transaction and
purports to state the following five counts against the Defendants: (i) breach
of fiduciary duty, (ii) violation of Florida's Deceptive and Unfair Trade
Practices Act, (iii) conspiracy to defraud, (iv) fraud, and (v) violation of
Florida Securities and Investor Protection Act. Mr. Spiegel is seeking $22.0
million in damages. On March 8, 2006, Defendants filed a motion to dismiss the
Spiegel Action.

         The Company has agreed with Messrs. Friedman, Siegel, Kart and Udell to
advance the costs of defense in connection with the Spiegel Action. Under
applicable provisions of Delaware law, the Company may be responsible to
indemnify each of the Defendants in connection with the Spiegel Action. The
final outcome of the Spiegel Action will most likely take an indefinite time to
resolve.

         GERALD ZUTLER

         In January 2003, DriverShield CRM Corp., or DriverShield, then a
wholly-owned subsidiary of the Company's predecessor, Accessity, was served with
a complaint filed by Mr. Gerald Zutler, its former President and Chief Operating
Officer, alleging, among other things, that DriverShield breached his employment
contract, that there was fraudulent concealment of DriverShield's intention to
terminate its employment agreement with Mr. Zutler, and discrimination on the
basis of age and aiding and abetting violation of the New York State Human
Rights Law. The complaint was filed in the Supreme Court of the State of New
York, County of Nassau, Index No.: 654/03. Mr. Zutler is seeking damages
aggregating $2.225 million, plus punitive damages and reasonable attorneys'
fees. DriverShield's management believes that DriverShield properly terminated
Mr. Zutler's employment for cause, and intends to vigorously defend this suit.
An Answer to the complaint was served by DriverShield on February 28, 2003. In
2003, Mr. Zutler filed a motion to have DriverShield's attorney removed from the
case. The motion was granted by the court, but was subsequently overturned by an
appellate court. DriverShield has filed a claim with its insurance carrier under
its directors and officers and employment practices' liability policy. The
carrier has agreed to cover certain portions of the claim as they relate to Mr.
Siegel, DriverShield's former Chief Executive Officer. The policy has a $50,000
deductible and a liability limit of $3.0 million per policy year. At the present
time, the carrier has agreed to cover the portion of the claim that relates to
Mr. Siegel and has agreed to a fifty percent allocation of expenses.

         MERCATOR GROUP, LLC

         The Company filed a Demand for Arbitration against Presidion Solutions,
Inc., or Presidion, alleging that Presidion breached the terms of the Memorandum
of Understanding, or the MOU, between Accessity and Presidion dated January 17,
2003. The Company sought a break-up fee of $250,000 pursuant to the terms of the
MOU alleging that Presidion breached the MOU by wrongfully terminating the MOU.
Additionally, the Company sought out of pocket costs of its due diligence
amounting to approximately $37,000. Presidion filed a counterclaim against the
Company alleging that the Company had breached the MOU and therefore owes
Presidion a break-up fee of $250,000. The dispute was heard by a single
arbitrator before the American Arbitration Association in Broward County,
Florida in late February 2004. During June 2004, the arbitrator awarded the
Company the $250,000 break-up fee set forth in the MOU between the Company and
Presidion, as well as the Company's share of the costs of the arbitration and
interest from the date of the termination by Presidion of the MOU, aggregating
approximately $280,000. During the third quarter of 2004, Presidion paid the
Company the full amount of the award with accrued interest. The arbitrator
dismissed Presidion's counterclaim against the Company.

         In 2003, the Company filed a lawsuit seeking damages in excess of $100
million as a result of information obtained during the course of the arbitration
discussed above, against: (i) Presidion Corporation, f/k/a MediaBus Networks,
Inc., Presidion's parent corporation, (ii) Presidion's investment bankers,
Mercator Group, LLC, or Mercator, and various related and affiliated parties and
(iii) Taurus Global LLC, or Taurus, (collectively referred to as the "Mercator
Action"), alleging that these parties committed a number of wrongful acts,
including, but not limited to tortuously interfering in the transaction between
the Company and Presidion. In 2004, the Company dismissed this lawsuit without
prejudice, which was filed in Florida state court. The Company recently refiled
this action in the State of California, for a similar amount, as the Company
believes this to be the proper jurisdiction. On August 18, 2005, the court
stayed the action and ordered the parties to arbitration. The parties agreed to
mediate the matter. Mediation took place on December 9, 2005 and was not
successful. On December 5, 2005, the Company filed a Demand for Arbitration with
the American Arbitration Association. On April 6, 2006, a single arbitrator was
appointed. The final outcome of the Mercator Action will most likely take an
indefinite time to resolve. The Company currently has limited information
regarding the financial condition of the defendants and the extent of their
insurance coverage. Therefore, it is possible that the Company may prevail, but
may not be able to collect any judgment. The share exchange agreement relating
to the Share Exchange Transaction provides that following full and final
settlement or other final resolution of the Mercator Action, after deduction of
all fees and expenses incurred by the law firm representing the Company in this
action and payment of the 25% contingency fee to the law firm, shareholders of
record of Accessity on the date immediately preceding the closing date of the
Share Exchange Transaction will receive two-thirds and the Company will retain
the remaining one-third of the net proceeds from any Mercator Action recovery.

                               -------------------

1. In connection with Pacific Ethanol California, Inc.'s private offering on
March 23, 2005, the Company was obligated under a registration rights agreement
(the "REGISTRATION RIGHTS AGREEMENT"), related to the above financing to file,
on the 151st day following March 23, 2005, a registration statement (the
"REGISTRATION STATEMENT") with the Securities and Exchange Commission (the
"COMMISSION"), registering for resale shares of common stock, and shares of
common stock underlying investor warrants and certain of the placement agent
warrants, issued in connection with the private offering. If (i) the Company did
not file the Registration Statement within the time period prescribed, or (ii)
the Company failed to file with the Commission a request for acceleration in
accordance with Rule 461 promulgated under the Securities Act of 1933, within
five trading days of the date that the Company is notified (orally or in
writing, whichever is earlier) by the Commission that the Registration Statement
will not be "reviewed," or is not subject to further review, or (iii) the
Registration Statement filed or required to be filed under the Registration
Rights Agreement was not declared effective by the Commission on or before
November 3, 2005, or (iv) after the Registration Statement is first declared
effective by the Commission, it ceases for any reason to remain continuously
effective as to all securities registered thereunder, or the holders of such
securities are not permitted to utilize the prospectus contained in the
Registration Statement to resell such securities, for more than an aggregate of
45 trading days during any 12-month period (which need not be consecutive
trading days) (any such failure or breach being referred to as an "Event," and
for purposes of clause (i) or (iii) the date on which such Event occurs, or for
purposes of clause (ii) the date on which such five-trading day period is
exceeded, or for purposes of clause (iv) the date on which such 45-trading
day-period is exceeded being referred to as "EVENT DATE"), then in addition to
any other rights the holders of such securities may have under the Registration
Statement or under applicable law, then, on each such Event Date and on each
monthly anniversary of each such Event Date (if the applicable Event shall not
have been cured by such date) until the applicable Event is cured, the Company
is required to pay to each such holder an amount in cash, as partial liquidated
damages and not as a penalty, equal to 2.0% of the aggregate purchase price paid
by such holder pursuant to the Securities Purchase Agreement relating to such
securities then held by such holder. If the Company fails to pay any partial
liquidated damages in full within seven days after the date payable, the Company
is required to pay interest thereon at a rate of 18% per annum (or such lesser
maximum amount that is permitted to be paid by applicable law) to such holder,
accruing daily from the date such partial liquidated damages are due until such
amounts, plus all such interest thereon, are paid in full. The partial
liquidated damages are to apply on a daily pro-rata basis for any portion of a
month prior to the cure of an Event.

         The Registration Rights Agreement also provides for customary
piggy-back registration rights whereby certain holders of shares of the
Company's common stock, or warrants to purchase shares of the Company's common
stock, can cause the Company to register such shares for resale in connection
with the Company's filing of a registration statement with the Commission to
register shares in another offering. The Registration Rights Agreement also
contains customary representations and warranties, covenants and limitations.

2. In connection with the issuance of the Series A Preferred Stock, the Company
entered into a Registration Rights and Stockholders Agreement (the "RIGHTS
AGREEMENT") with Cascade Investment, L.L.C. ("CASCADE"). The Rights Agreement is
to be effective until the holders of the Series A Preferred Stock, and their
affiliates, as a group, own less than 10% of the Series A Preferred Stock issued
under the purchase agreement with Cascade, including common stock into which
such Series A Preferred Stock has been converted (the "TERMINATION DATE"). The
Rights Agreement provides that holders of a majority of the Series A Preferred
Stock, including common stock into which the Series A Preferred Stock has been
converted, may demand and cause the Company, at any time after April 13, 2007,
to register on their behalf the shares of common stock issued, issuable or that
may be issuable upon conversion of the Series A Preferred Stock (the
"REGISTRABLE SECURITIES"). Following such demand, the Company is required to
notify any other holders of the Series A Preferred Stock or Registrable
Securities of the Company's intent to file a registration statement and, to the
extent requested by such holders, include them in the related registration
statement. The Company is required to keep such registration statement effective
until such time as all of the Registrable Securities are sold or until such
holders may avail themselves of Rule 144(k) under the Securities Act of 1933,
which requires, among other things, a minimum two-year holding period and
requires that any holder availing itself of Rule 144(k) not be an affiliate of
the Company. The holders are entitled to three demand registrations on Form S-1
and unlimited demand registrations on Form S-3; however, the Company is not
obligated to effect more than two demand registrations on Form S-3 in any
12-month period.

         In addition to the demand registration rights afforded the holders
under the Rights Agreement, the holders are entitled to "piggyback" registration
rights. These rights entitle the holders who so elect to be included in
registration statements to be filed by the Company with respect to other
registrations of equity securities in connection with underwritten offerings of
such securities. The holders are entitled to unlimited "piggyback" registration
rights.

         The Rights Agreement provides for the initial appointment of two
persons designated by Cascade to the Company's Board of Directors, and the
appointment of one of such persons as the Chairman of the Compensation Committee
of the Board of Directors. Following the Termination Date, Cascade is required
to cause its director designees, and all other designees, to resign from all
applicable committees and boards of directors, effective as of the Termination
Date.

3. In connection with Pacific Ethanol California, Inc.'s private offerings in
February 2004, May 2004 and December 2004, it granted registration rights to the
investors in those offerings. Those registration obligations became the
Company's in connection with the share exchange transaction that occurred in
March 2005. The shares issued in connection with those offerings and the shares
underlying warrants issued in connection with those offerings, including
placement agent warrants, have been previously registered for resale pursuant to
an effective registration statement on Form S-1.

4. The Company also had or has registration rights outstanding in favor of
Helain Kaplan, Doug Dickson, Paul Koehler, Jeff Manternach, Rotom Enterprises,
Inc., Jack Skidell (as successor to Colin Winthrop & Co., Inc.), and Barry
Siegel. Those registration obligations became the Company's in connection with
the share exchange transaction that occurred in March 2005. The shares issued to
such persons or entities and/or the shares underlying warrants issued to such
persons or entities have been previously registered for resale pursuant to an
effective registration statement on Form S-1.

certifies that, for value received, ____________ or its registered assigns (the

owner hereof for the purpose of any exercise hereof or any distribution to the
Holder, and for all other purposes, absent actual notice to the contrary.

         3. REGISTRATION OF TRANSFERS. The Company shall register the transfer
of any portion of this Warrant in the Warrant Register, upon surrender of this
Warrant, with the Form of Assignment attached hereto duly completed and signed,
to the Transfer Agent or to the Company at its address specified herein. Upon
any such registration or transfer, a new warrant to purchase Common Stock, in
substantially the form of this Warrant (any such new warrant, a "NEW WARRANT"),
evidencing the portion of this Warrant so transferred shall be issued to the
transferee and a New Warrant evidencing the remaining portion of this Warrant
not so transferred, if any, shall be issued to the transferring Holder. The
acceptance of the New Warrant by the transferee thereof shall be deemed the
acceptance by such transferee of all of the rights and obligations of a holder
of a Warrant.

         4. EXERCISE AND DURATION OF WARRANTS.

                  (a) This Warrant shall be exercisable by the registered Holder
from time to time on or after a date that is the later of (i) six (6) months
from the date hereof and (ii) the Effective Date of the Registration Statement,
to and including the Expiration Date. At 6:30 P.M., New York City time on the
Expiration Date, the portion of this Warrant not exercised prior thereto shall
be and become void and of no value; provided that, if the average of the Closing
Prices for the five Trading Days immediately prior to (but not including) the
Expiration Date exceeds the Exercise Price on the Expiration Date, provided
further that, if on the Expiration date, there is no effective Registration
Statement covering the resale of the Warrant Shares, then this Warrant shall be
deemed to have been exercised in full (to the extent not previously exercised)
on a "cashless exercise" basis at 6:30 P.M. New York City time on the Expiration
Date. Notwithstanding anything to the contrary herein, the Expiration Date shall
be extended for each day following the Required Effectiveness Date that the
Registration Statement is not effective.

                  (b) A Holder may exercise this Warrant by delivering to the
Company (i) an exercise notice, in the form attached hereto (the "EXERCISE
NOTICE"), appropriately completed and duly signed, and (ii) payment of the
Exercise Price for the number of Warrant Shares as to which this Warrant is
being exercised (which may take the form of a "cashless exercise" if so
indicated in the Exercise Notice only if a "cashless exercise" may occur at such
time pursuant to Section 10 below), and the date such items are delivered to the
Company (as determined in accordance with the notice provisions hereof) is an
"EXERCISE DATE." The Holder shall not be required to deliver the original
Warrant in order to effect an exercise hereunder. Execution and delivery of the
Exercise Notice shall have the same effect as cancellation of the original
Warrant and issuance of a New Warrant evidencing the right to purchase the
remaining number of Warrant Shares.

         5. DELIVERY OF WARRANT SHARES.

                  (a) Upon exercise of this Warrant, the Company shall promptly
(but in no event later than three Trading Days after the Exercise Date) issue or
cause to be issued and cause to be delivered to or upon the written order of the
Holder and in such name or names as the Holder may designate, a certificate for
the Warrant Shares issuable upon such exercise, free of restrictive legends
unless a registration statement covering the resale of the Warrant Shares and
naming the Holder as a selling stockholder thereunder is not then effective and

                                       2

<PAGE>

the Warrant Shares are not freely transferable without volume restrictions
pursuant to Rule 144 under the Securities Act. The Holder, or any Person so
designated by the Holder to receive Warrant Shares, shall be deemed to have
become holder of record of such Warrant Shares as of the Exercise Date. The
Company shall, upon request of the Holder, use its best efforts to deliver
Warrant Shares hereunder electronically through the Depository Trust Corporation
or another established clearing corporation performing similar functions.

                  (b) This Warrant is exercisable, either in its entirety or,
from time to time, for a portion of the number of Warrant Shares. Upon surrender
of this Warrant following one or more partial exercises, the Company shall issue
or cause to be issued, at its expense, a New Warrant evidencing the right to
purchase the remaining number of Warrant Shares.

                  (c) In addition to any other rights available to a Holder, if
the Company fails to deliver to the Holder a certificate representing Warrant
Shares by the third Trading Day after the date on which delivery of such
certificate is required by this Warrant, and if after such third Trading Day the
Holder purchases (in an open market transaction or otherwise) shares of Common
Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares
that the Holder anticipated receiving from the Company (a "BUY-IN"), then the
Company shall, within three Trading Days after the Holder's written request and
in the Holder's discretion, either (i) pay cash to the Holder in an amount equal
to the Holder's total purchase price (including brokerage commissions, if any)
for the shares of Common Stock so purchased (the "BUY-IN PRICE"), at which point
the Company's obligation to deliver such certificate (and to issue such Common
Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the
Holder a certificate or certificates representing such Common Stock and pay cash
to the Holder in an amount equal to the excess (if any) of the Buy-In Price over
the product of (A) such number of shares of Common Stock, times (B) the Closing
Price on the date of the event giving rise to the Company's obligation to
deliver such certificate.

                  (d) The Company's obligations to issue and deliver Warrant
Shares in accordance with the terms hereof are absolute and unconditional,
irrespective of any action or inaction by the Holder to enforce the same, any
waiver or consent with respect to any provision hereof, the recovery of any
judgment against any Person or any action to enforce the same, or any setoff,
counterclaim, recoupment, limitation or termination, or any breach or alleged
breach by the Holder or any other Person of any obligation to the Company or any
violation or alleged violation of law by the Holder or any other Person, and
irrespective of any other circumstance which might otherwise limit such
obligation of the Company to the Holder in connection with the issuance of
Warrant Shares. Nothing herein shall limit a Holder's right to pursue any other
remedies available to it hereunder, at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief with
respect to the Company's failure to timely deliver certificates representing
shares of Common Stock upon exercise of the Warrant as required pursuant to the
terms hereof.

         6. CHARGES, TAXES AND EXPENSES. Issuance and delivery of certificates
for shares of Common Stock upon exercise of this Warrant shall be made without
charge to the Holder for any issue or transfer tax, withholding tax, transfer
agent fee or other incidental tax or expense in respect of the issuance of such
certificates, all of which taxes and expenses shall be paid by the Company;
provided, however, that the Company shall not be required to pay any tax which

                                       3

<PAGE>

may be payable in respect of any transfer involved in the registration of any
certificates for Warrant Shares or Warrants in a name other than that of the
Holder. The Holder shall be responsible for all other tax liability that may
arise as a result of holding or transferring this Warrant or receiving Warrant
Shares upon exercise hereof.

         7. REPLACEMENT OF WARRANT. If this Warrant is mutilated, lost, stolen
or destroyed, the Company shall issue or cause to be issued in exchange and
substitution for and upon cancellation hereof, or in lieu of and substitution
for this Warrant, a New Warrant, but only upon receipt of evidence reasonably
satisfactory to the Company of such loss, theft or destruction and customary and
reasonable bond or indemnity, if requested. Applicants for a New Warrant under
such circumstances shall also comply with such other reasonable regulations and
procedures and pay such other reasonable third-party costs as the Company may
prescribe.

         8. RESERVATION OF WARRANT SHARES. The Company covenants that it will at
all times reserve and keep available out of the aggregate of its authorized but
unissued and otherwise unreserved Common Stock, solely for the purpose of
enabling it to issue Warrant Shares upon exercise of this Warrant as herein
provided, the number of Warrant Shares which are then issuable and deliverable
upon the exercise of this entire Warrant, free from preemptive rights or any
other contingent purchase rights of persons other than the Holder (after giving
effect to the adjustments and restrictions of SECTION 9, if any). The Company
covenants that all Warrant Shares so issuable and deliverable shall, upon the
due exercise of this Warrant, and upon issuance of such Warrant Shares and the
payment of the applicable Exercise Price in accordance with the terms hereof, be
duly and validly authorized, issued and fully paid and nonassessable. The
Company will take all such action as may be necessary to assure that such shares
of Common Stock may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of any securities exchange
or automated quotation system upon which the Common Stock may be listed.

         9. CERTAIN ADJUSTMENTS. The Exercise Price and number of Warrant Shares
issuable upon exercise of this Warrant are subject to adjustment from time to
time as set forth in this SECTION 9.

                  (a) STOCK DIVIDENDS AND SPLITS. If the Company, at any time
while this Warrant is outstanding, (i) pays a stock dividend on its Common Stock
or otherwise makes a distribution on any class of capital stock that is payable
in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock
into a larger number of shares, or (iii) combines outstanding shares of Common
Stock into a smaller number of shares, then in each such case the Exercise Price
shall be multiplied by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding immediately before such event and of which
the denominator shall be the number of shares of Common Stock outstanding
immediately after such event. Any adjustment made pursuant to clause (i) of this
paragraph shall become effective immediately after the record date for the
determination of stockholders entitled to receive such dividend or distribution,
and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall
become effective immediately after the effective date of such subdivision or
combination.

                                       4

<PAGE>

                  (b) PRO RATA DISTRIBUTIONS. If the Company, at any time while
this Warrant is outstanding, distributes to holders of Common Stock (i)
evidences of its indebtedness, (ii) any security (other than a distribution of
Common Stock covered by the preceding paragraph), (iii) rights or warrants to
subscribe for or purchase any security, or (iv) any other asset (in each case,
"DISTRIBUTED PROPERTY"), then in each such case the Holder shall be entitled
upon exercise of this Warrant for the purchase of any or all of the Warrant
Shares, to receive the amount of Distributed Property which would have been
payable to the Holder had such Holder been the holder of such Warrant Shares on
the record date for the determination of stockholders entitled to such
Distributed Property. The Company will at all times set aside in escrow and keep
available for distribution to such holder upon exercise of this Warrant a
portion of the Distributed Property to satisfy the distribution to which such
Holder is entitled pursuant to the preceding sentence.

                  (c) FUNDAMENTAL TRANSACTIONS. If, at any time while this
Warrant is outstanding and exercisable, (i) the Company effects any merger or
consolidation of the Company with or into another Person, (ii) the Company
effects any sale of all or substantially all of its assets in one or a series of
related transactions, (iii) any tender offer or exchange offer (whether by the
Company or another Person) is completed pursuant to which holders of Common
Stock are permitted to tender or exchange their shares for other securities,
cash or property, or (iv) the Company effects any reclassification of the Common
Stock or any compulsory share exchange pursuant to which the Common Stock is
effectively converted into or exchanged for other securities, cash or property
(other than as a result of a subdivision or combination of shares of Common
Stock covered by Section 9(a) above) (in any such case, a "FUNDAMENTAL
TRANSACTION"), then the Holder shall have the right thereafter to receive, upon
exercise of this Warrant, the same amount and kind of securities, cash or
property as it would have been entitled to receive upon the occurrence of such
Fundamental Transaction if it had been, immediately prior to such Fundamental
Transaction, the holder of the number of Warrant Shares then issuable upon
exercise in full of this Warrant (the "ALTERNATE CONSIDERATION"). The aggregate
Exercise Price for this Warrant will not be affected by any such Fundamental
Transaction, but the Company shall apportion such aggregate Exercise Price among
the Alternate Consideration in a reasonable manner reflecting the relative value
of any different components of the Alternate Consideration. If holders of Common
Stock are given any choice as to the securities, cash or property to be received
in a Fundamental Transaction, then the Holder shall be given the same choice as
to the Alternate Consideration it receives upon any exercise of this Warrant
following such Fundamental Transaction. At the Holder's request, any successor
to the Company or surviving entity in such Fundamental Transaction shall issue
to the Holder a new warrant consistent with the foregoing provisions and
evidencing the Holder's right to purchase the Alternate Consideration for the
aggregate Exercise Price upon exercise thereof. The terms of any agreement
pursuant to which a Fundamental Transaction is effected shall include terms
requiring any such successor or surviving entity to comply with the provisions
of this paragraph (c) and insuring that the Warrant (or any such replacement
security) will be similarly adjusted upon any subsequent transaction analogous
to a Fundamental Transaction. If any Fundamental Transaction constitutes or
results in (a) a "going private" transaction as defined in Rule 13e-3 under the
Exchange Act, or (b) an acquisition primarily for cash, or (c) an acquisition,
merger or sale with or into a Person not traded on an Eligible Market, then the
Company (or any such successor or surviving entity) will redeem this Warrant
from the Holder for a purchase price, payable in cash on the closing date of
such "going private" transaction, equal to the Black Scholes value of the
remaining unexercised portion of this Warrant on the closing date of such "going
private" transaction.

<PAGE>

                  (d) NUMBER OF WARRANT SHARES. Simultaneously with any
adjustment to the Exercise Price pursuant to paragraph (a) of this Section, the
number of Warrant Shares that may be purchased upon exercise of this Warrant
shall be increased proportionately, so that after such adjustment the aggregate
Exercise Price payable hereunder for the increased number of Warrant Shares
shall be the same as the aggregate Exercise Price in effect immediately prior to
such adjustment.

                  (e) CALCULATIONS. All calculations under this SECTION 9 shall
be made to the nearest cent or the nearest 1/100th of a share, as applicable.
The number of shares of Common Stock outstanding at any given time shall not
include shares owned or held by or for the account of the Company, and the
disposition of any such shares shall be considered an issue or sale of Common
Stock.

                  (f) NOTICE OF ADJUSTMENTS. Upon the occurrence of each
adjustment pursuant to this SECTION 9, the Company at its expense will promptly
compute such adjustment in accordance with the terms of this Warrant and prepare
a certificate setting forth such adjustment, including a statement of the
adjusted Exercise Price and adjusted number or type of Warrant Shares or other
securities issuable upon exercise of this Warrant (as applicable), describing
the transactions giving rise to such adjustments and showing in detail the facts
upon which such adjustment is based. Upon written request, the Company will
promptly deliver a copy of each such certificate to the Holder and to the
Company's Transfer Agent.

                  (g) NOTICE OF CORPORATE EVENTS. If the Company (i) declares a
dividend or any other distribution of cash, securities or other property in
respect of its Common Stock, including without limitation any granting of rights
or warrants to subscribe for or purchase any capital stock of the Company or any
Subsidiary, (ii) authorizes or approves, enters into any agreement contemplating
or solicits stockholder approval for any Fundamental Transaction or (iii)
authorizes the voluntary dissolution, liquidation or winding up of the affairs
of the Company, then the Company shall deliver to the Holder a notice describing
the material terms and conditions of such transaction, at least ten calendar
days prior to the applicable record or effective date on which a Person would
need to hold Common Stock in order to participate in or vote with respect to
such transaction, and the Company will take all steps reasonably necessary in
order to insure that the Holder is given the practical opportunity to exercise
this Warrant prior to such time so as to participate in or vote with respect to
such transaction; provided, however, that the failure to deliver such notice or
any defect therein shall not affect the validity of the corporate action
required to be described in such notice.

         10. PAYMENT OF EXERCISE PRICE. The Holder shall pay the Exercise Price
in immediately available funds; provided, however, that if at any time after the
Required Effective Date a Registration Statement covering the resale of the
Warrant Shares is not effective on the Exercise Date, the Holder may satisfy its
obligation to pay the Exercise Price through a "cashless exercise," in which
event the Company shall issue to the Holder the number of Warrant Shares
determined as follows:

                                       6

<PAGE>

                                 X = Y [(A-B)/A]
                  where:
                                 X = the number of Warrant Shares to be issued
                                 to the Holder.

                                 Y = the number of Warrant Shares with
                                 respect to which this Warrant is
                                 being exercised.

                                 A = the average of the Closing Prices
                                 for the five Trading Days immediately
                                 prior to (but not including) the
                                 Exercise Date.

                                 B = the Exercise Price.

                  For purposes of Rule 144 promulgated under the Securities Act,
it is intended, understood and acknowledged that the Warrant Shares issued in a
cashless exercise transaction shall be deemed to have been acquired by the
Holder, and the holding period for the Warrant Shares shall be deemed to have
commenced, on the date this Warrant was originally issued pursuant to the
Purchase Agreement.

         11. LIMITATION ON EXERCISE.

                  (a) Notwithstanding anything to the contrary contained herein,
the number of shares of Common Stock that may be acquired by the Holder upon any
exercise of this Warrant (or otherwise in respect hereof) shall be limited to
the extent necessary to insure that, following such exercise (or other
issuance), the total number of shares of Common Stock then beneficially owned by
such Holder and its Affiliates and any other Persons whose beneficial ownership
of Common Stock would be aggregated with the Holder's for purposes of Section
13(d) of the Exchange Act, does not exceed 4.999% (the "MAXIMUM PERCENTAGE") of
the total number of issued and outstanding shares of Common Stock (including for
such purpose the shares of Common Stock issuable upon such exercise). For such
purposes, beneficial ownership shall be determined in accordance with Section
13(d) of the Exchange Act and the rules and regulations promulgated thereunder.
Each delivery of an Exercise Notice hereunder will constitute a representation
by the Holder that it has evaluated the limitation set forth in this paragraph
and determined that issuance of the full number of Warrant Shares requested in
such Exercise Notice is permitted under this paragraph. The Company's obligation
to issue shares of Common Stock in excess of the limitation referred to in this
Section shall be suspended (and shall not terminate or expire notwithstanding
any contrary provisions hereof) until such time, if any, as such shares of
Common Stock may be issued in compliance with such limitation, but in no event
later than the Expiration Date. By written notice to the Company, the Holder may
waive the provisions of this Section or increase or decrease the Maximum
Percentage to any other percentage specified in such notice, but (i) any such
waiver or increase will not be effective until the 61st day after such notice is
delivered to the Company, and (ii) any such waiver or increase or decrease will
apply only to the Holder and not to any other holder of Warrants.

                                       7

<PAGE>

         12. FRACTIONAL SHARES. The Company shall not be required to issue or
cause to be issued fractional Warrant Shares on the exercise of this Warrant. If
any fraction of a Warrant Share would, except for the provisions of this
Section, be issuable upon exercise of this Warrant, the number of Warrant Shares
to be issued will be rounded up to the nearest whole share.

         13. NOTICES. Any and all notices or other communications or deliveries
hereunder (including without limitation any Exercise Notice) shall be in writing
and shall be deemed given and effective on the earliest of (i) the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile number specified in the Purchase Agreement prior to 6:30 p.m. (New
York City time) on a Trading Day, (ii) the next Trading Day after the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile number specified in the Purchase Agreement on a day that is not a
Trading Day or later than 6:30 p.m. (New York City time) on any Trading Day,
(iii) the Trading Day following the date of mailing, if sent by nationally
recognized overnight courier service, or (iv) upon actual receipt by the party
to whom such notice is required to be given. The address for such notices or
communications shall be as set forth in the Purchase Agreement.

         14. WARRANT AGENT. The Company shall serve as warrant agent under this
Warrant. Upon 30 days' notice to the Holder, the Company may appoint a new
warrant agent. Any corporation into which the Company or any new warrant agent
may be merged or any corporation resulting from any consolidation to which the
Company or any new warrant agent shall be a party or any corporation to which
the Company or any new warrant agent transfers substantially all of its
corporate trust or stockholders services business shall be a successor warrant
agent under this Warrant without any further act. Any such successor warrant
agent shall promptly cause notice of its succession as warrant agent to be
mailed (by first class mail, postage prepaid) to the Holder at the Holder's last
address as shown on the Warrant Register.

         15. MISCELLANEOUS.

                  (a) Subject to the restrictions on transfer set forth on the
first page hereof, this Warrant may be assigned by the Holder. This Warrant may
not be assigned by the Company except to a successor in the event of a
Fundamental Transaction. This Warrant shall be binding on and inure to the
benefit of the parties hereto and their respective successors and assigns.
Subject to the preceding sentence, nothing in this Warrant shall be construed to
give to any Person other than the Company and the Holder any legal or equitable
right, remedy or cause of action under this Warrant. This Warrant may be amended
only in writing signed by the Company and the Holder and their successors and
assigns.

                  (b) The Company will not, by amendment of its governing
documents or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms of this
Warrant, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the Holder against impairment.
Without limiting the generality of the foregoing, the Company (i) will not
increase the par value of any Warrant Shares above the amount payable therefor
on such exercise, (ii) will take all such action as may be reasonably necessary
or appropriate in order that the Company may validly and legally issue fully

                                       8

<PAGE>

paid and nonassessable Warrant Shares on the exercise of this Warrant, and (iii)
will not close its stockholder books or records in any manner which interferes
with the timely exercise of this Warrant.

                  (C) GOVERNING LAW; VENUE; WAIVER OF JURY TRIAL. ALL QUESTIONS
CONCERNING THE CONSTRUCTION, VALIDITY, ENFORCEMENT AND INTERPRETATION OF THIS
WARRANT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK. EACH PARTY HEREBY IRREVOCABLY SUBMITS TO THE
EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS SITTING IN THE CITY OF
NEW YORK, BOROUGH OF MANHATTAN, FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR
IN CONNECTION HEREWITH OR WITH ANY TRANSACTION CONTEMPLATED HEREBY OR DISCUSSED
HEREIN (INCLUDING WITH RESPECT TO THE ENFORCEMENT OF ANY OF THE TRANSACTION
DOCUMENTS), AND HEREBY IRREVOCABLY WAIVES, AND AGREES NOT TO ASSERT IN ANY SUIT,
ACTION OR PROCEEDING, ANY CLAIM THAT IT IS NOT PERSONALLY SUBJECT TO THE
JURISDICTION OF ANY SUCH COURT, THAT SUCH SUIT, ACTION OR PROCEEDING IS
IMPROPER. EACH PARTY HEREBY IRREVOCABLY WAIVES PERSONAL SERVICE OF PROCESS AND
CONSENTS TO PROCESS BEING SERVED IN ANY SUCH SUIT, ACTION OR PROCEEDING BY
MAILING A COPY THEREOF VIA REGISTERED OR CERTIFIED MAIL OR OVERNIGHT DELIVERY
(WITH EVIDENCE OF DELIVERY) TO SUCH PARTY AT THE ADDRESS IN EFFECT FOR NOTICES
TO IT UNDER THIS AGREEMENT AND AGREES THAT SUCH SERVICE SHALL CONSTITUTE GOOD
AND SUFFICIENT SERVICE OF PROCESS AND NOTICE THEREOF. NOTHING CONTAINED HEREIN
SHALL BE DEEMED TO LIMIT IN ANY WAY ANY RIGHT TO SERVE PROCESS IN ANY MANNER
PERMITTED BY LAW. THE COMPANY HEREBY WAIVES ALL RIGHTS TO A TRIAL BY JURY.

                  (d) The headings herein are for convenience only, do not
constitute a part of this Warrant and shall not be deemed to limit or affect any
of the provisions hereof.

                  (e) In case any one or more of the provisions of this Warrant
shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Warrant shall not
in any way be affected or impaired thereby and the parties will attempt in good
faith to agree upon a valid and enforceable provision which shall be a
commercially reasonable substitute therefor, and upon so agreeing, shall
incorporate such substitute provision in this Warrant.

                             FORM OF EXERCISE NOTICE

(To be executed by the Holder to exercise the right to purchase shares of Common
Stock under the foregoing Warrant)

To:  PACIFIC ETHANOL, INC.

The undersigned is the Holder of Warrant No. _______ (the "WARRANT") issued by
Pacific Ethanol, Inc., a Delaware corporation (the "COMPANY"). Capitalized terms
used herein and not otherwise defined have the respective meanings set forth in
the Warrant.

1.       The Warrant is currently exercisable to purchase a total of
         ______________ Warrant Shares.

2.       The undersigned Holder hereby exercises its right to purchase
         _________________ Warrant Shares pursuant to the Warrant.

3.       The Holder intends that payment of the Exercise Price shall be made as
         (check one):

                           ____    "Cash Exercise" under Section 10

                           ____    "Cashless Exercise" under Section 10

4.       If the holder has elected a Cash Exercise, the holder shall pay the sum
         of $____________ to the Company in accordance with the terms of the
         Warrant.
