     a. Initial Mandatory
Registration. The Company shall prepare, and, as soon as practicable, but in
no event later than the Initial Filing Deadline, file with the SEC the Initial
Registration Statement on Form S-3 covering the resale of all of the Initial
Registrable Securities. In the event that Form S-3 is unavailable for such a
registration, the Company shall use such other form as is available for such a
registration on another appropriate form reasonably acceptable to the Required
Holders, subject to the provisions of Section 2(e). The Initial Registration
Statement prepared pursuant hereto shall register for resale at least the number
of shares of Common Stock equal to the Initial Required Registration Amount
determined as of date the Registration Statement is initially filed with the
SEC. The Initial Registration Statement shall contain (except if otherwise
directed by the Required Holders) the "Selling Stockholders" and "Plan
of Distribution" sections in substantially the form attached hereto as
Exhibit B. The Company shall use its best efforts to have the Initial
Registration Statement declared effective by the SEC as soon as practicable, but
in no event later than the Initial Effectiveness Deadline. By 9:30 am on the
date following the Initial Effective Date, the Company shall file with the SEC
in accordance with Rule 424 under the 1933 Act the final prospectus to be used
in connection with sales pursuant to such Registration Statement. 

     b. Additional Mandatory
Registrations. The Company shall prepare, and, as soon as practicable but in
no event later than the Additional Filing Deadline, file with the SEC an
Additional Registration Statement on Form S-3 covering the resale of all of the
Additional Registrable Securities not previously registered on an Additional
Registration 

Statement hereunder. To the extent the staff of the SEC does
not permit the Additional Required Registration Amount to be registered on the
Additional Registration Statement, which are Cutback Shares hereunder, the
Company shall file Additional Registration Statements successively trying to
register on each such Additional Registration Statement the maximum number of
remaining Additional Registrable Securities until the Additional Required
Registration Amount has been registered with the SEC. In the event that Form S-3
is unavailable for such a registration, the Company shall use such other form as
is available for such a registration on another appropriate form reasonably
acceptable to the Required Holders, subject to the provisions of Section 2(e).
Each Additional Registration Statement prepared pursuant hereto shall register
for resale at least that number of shares of Common Stock equal to the
Additional Required Registration Amount as of date the Registration Statement is
initially filed with the SEC. Each Additional Registration Statement shall
contain (except if otherwise directed by the Required Holders) the "Selling
Stockholders" and "Plan of Distribution" sections in substantially
the form attached hereto as Exhibit B. The Company shall use its best
efforts to have each Additional Registration Statement declared effective by the
SEC as soon as practicable, but in no event later than the Additional
Effectiveness Deadline. By 9:30 am on the date following the Additional
Effective Date, the Company shall file with the SEC in accordance with Rule 424
under the 1933 Act the final prospectus to be used in connection with sales
pursuant to such Registration Statement. 

     c. Allocation of Registrable
Securities. The initial number of Registrable Securities included in any
Registration Statement and any increase in the number of Registrable Securities
included therein shall be allocated pro rata among the Investors based on the
number of Registrable Securities held by each Investor at the time the
Registration Statement covering such initial number of Registrable Securities or
increase thereof is declared effective by the SEC. In the event that an Investor
sells or otherwise transfers any of such Investor's Registrable Securities, each
transferee shall be allocated a pro rata portion of the then remaining number of
Registrable Securities included in such Registration Statement for such
transferor. Any shares of Common Stock included in a Registration Statement and
which remain allocated to any Person which ceases to hold any Registrable
Securities covered by such Registration Statement shall be allocated to the
remaining Investors, pro rata based on the number of Registrable Securities then
held by such Investors which are covered by such Registration Statement. In no
event shall the Company include any securities other than Registrable Securities
on any Registration Statement filed with the SEC during the 12-month period
following the Closing Date without the prior written consent of the Required
Holders except for up to 912,511 shares of Common Stock issuable by the Company
upon exercise of warrants issued by the Company to Knight Capital Markets, LLC.
If the SEC requires that the Company register less than the amount of shares of
Common Stock originally included on any Registration Statement at the time it
was filed, the Registrable Securities on such registration statement and any
other securities allowed to be registered on such Registration Statement (as set
forth below) shall be decreased on a pro rata basis.

     d. Legal Counsel. Subject
to Section 5 hereof, the Required Holders shall have the right to select one
legal counsel to review and oversee any registration pursuant to this Section 2
("Legal Counsel"), which shall be Richardson & Patel LLP or such
other counsel as thereafter designated by the Required Holders. The Company and
Legal Counsel shall 

reasonably cooperate with each other in performing the Company's obligations under this Agreement. 

     e. Ineligibility for Form S-3.  In the event that Form S-3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall (i) register the resale of the Registrable
Securities on another appropriate form reasonably acceptable to the Required Holders and (ii) undertake to register the Registrable Securities on Form S-3 as soon as such form is available, provided that the Company shall maintain the effectiveness
of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective by the SEC. 

     f. Sufficient Number of Shares Registered. In the event the number of shares available under a Registration Statement filed pursuant to Section 2(a) is insufficient to cover all of the Registrable Securities
required to be covered by such Registration Statement or an Investor's allocated portion of the Registrable Securities pursuant to Section 2(b), the Company shall amend the applicable Registration Statement, or file a new Registration Statement (on
the short form available therefor, if applicable), or both, so as to cover at least the Required Registration Amount as of the trading day immediately preceding the date of the filing of such amendment or new Registration Statement, in each case, as
soon as practicable, but in any event not later than fifteen (15) days after the necessity therefor arises. The Company shall use its best efforts to cause such amendment and/or new Registration Statement to become effective as soon as practicable
following the filing thereof.  For purposes of the foregoing provision, the number of shares available under a Registration Statement shall be deemed "insufficient to cover all of the Registrable Securities" if at any time the number of shares of
Common Stock available for resale under the Registration Statement is less than the product determined by multiplying (i) the Required Registration Amount as of such time by (ii) 0.90. The calculation set forth in the foregoing sentence shall be
made without regard to any limitations on the conversion of the Notes or the exercise of the Warrants and such calculation shall assume that the Notes are then convertible into shares of Common Stock at the then prevailing Conversion Rate (as
defined in the Notes) and that the Warrants are then exercisable for shares of Common Stock at the then prevailing Exercise Price (as defined in the Warrants). 

     g. Effect of Failure to File and Obtain and Maintain Effectiveness of Registration Statement.

     (a) If (i) a Registration Statement covering all of the Registrable Securities required to be covered thereby and required to be filed by the Company pursuant to this Agreement is (A) not filed with the SEC on or before
the respective Filing Deadline (a "Filing Failure") or (B) not declared effective by the SEC on or before the respective Effectiveness Deadline (an "Effectiveness Failure") or (ii) on any day after the Effective Date sales of all of
the Registrable Securities required to be included on such Registration Statement cannot be made (other than during an Allowable Grace Period (as defined in Section 3(r)) pursuant to such Registration Statement or otherwise (including, without
limitation, because of a failure to keep such Registration Statement effective, to disclose such information as is necessary for sales to be made pursuant to such Registration Statement, to register a sufficient number of shares of Common Stock or
to maintain the listing of the shares of 

Common Stock) (a "Maintenance Failure") then, as liquidated damages and not as a penalty to any holder by reason of any such delay in or reduction of its ability to sell the underlying shares of Common Stock (which remedy shall be the
exclusive economic remedy available with respect to Filing Failures, Effectiveness Failures and Maintenance Failures), the Company shall pay to each holder of Registrable Securities relating to such Registration Statement an amount equal to one
percent (1.0%) of the aggregate Purchase Price (as such term is defined in the Securities Purchase Agreement) of such Investor's Registrable Securities included in such Registration Statement on each of the following dates: (i) the day of a Filing
Failure and on every thirtieth day (pro rated for periods totaling less than thirty days) thereafter until such Filing Failure is cured; (ii) the day of an Effectiveness Failure and on every thirtieth day (pro rated for periods totaling less than
thirty days) thereafter until such Effectiveness Failure is cured; (iii) the initial day of a Maintenance Failure and on every thirtieth day (pro rated for periods totaling less than thirty days) thereafter until such Maintenance Failure is cured.
If all of the Cutback Shares, if any, have not been registered on a Registration Statement which has been declared effective by the SEC on or before the one hundred fifty (150) day anniversary of the Closing Date (a "Cutback Failure") then,
as liquidated damages and not as a penalty to any holder by reason of any such delay in or reduction of its ability to sell any Cutback Shares (which remedy shall be the exclusive economic remedy available with respect to Cutback Failures), the
Company shall pay to each holder of Cutback Shares relating to such Registration Statement an amount equal to one quarter of a percent (0.25%) of the aggregate Purchase Price (as such term is defined in the Securities Purchase Agreement) of such
Investor's Cutback Shares included in such Registration Statement on the day of a Cutback Failure and on every thirtieth day (pro rated for periods totaling less than thirty days) thereafter until such Cutback Failure is cured. The payments to which
a holder shall be entitled pursuant to this Section 2(g) are referred to herein as "Registration Delay Payments." Registration Delay Payments shall be paid on the day of the Filing Failure, Effectiveness Failure, Cutback Failure or the
initial day of Maintenance Failure, as applicable, and thereafter on the earlier of (I) on the thirtieth day after the event or failure giving rise to the Registration Delay Payments are incurred and (II) the third Business Day after the event or
failure giving rise to the Registration Delay Payments is cured.  The date such Registration Delay Payments are due shall be referred to herein as a "Registration Delay Payments Payment Date."  In the event the Company fails to make
Registration Delay Payments in a timely manner, such Registration Delay Payments shall bear interest at the rate of one and one-half percent (1.5%) per month (prorated for partial months) until paid in full. Notwithstanding anything herein or in the
Securities Purchase Agreement to the contrary, in no event shall the aggregate amount of Registration Delay Payments (other than Registration Delay Payments payable pursuant to events that are within the control of the Company) exceed, in the
aggregate, 24% of the aggregate Purchase Price. 

     (b) Registration Delay Payments shall be payable on each Registration Delay Payments Payment Date, to each holder of Registrable Securities relating to such Registration Statement, in cash. 

3. Related Obligations. 

     At such time as the Company is obligated to file a Registration Statement with the SEC pursuant to Section 2(a), 2(d) or 2(e), the Company will use its best efforts to effect the 

registration of the Registrable Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Company shall have the following obligations: 

     a. The Company shall submit to the SEC, within two (2) Business Days after the Company learns that no review of a particular Registration Statement will be made by the staff of the SEC or that the staff has no further
comments on a particular Registration Statement, as the case may be, a request for acceleration of effectiveness of such Registration Statement to a time and date not later than 48 hours after the submission of such request. The Company shall keep
each Registration Statement effective pursuant to Rule 415 at all times until the earlier of (i) the date as of which the Investors may sell all of the Registrable Securities covered by such Registration Statement without restriction pursuant to
Rule 144(k) (or any successor thereto) promulgated under the 1933 Act or (ii) the date on which the Investors shall have sold all of the Registrable Securities covered by such Registration Statement (the "Registration Period"). The Company
shall ensure that each Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated
therein, or necessary to make the statements therein (in the case of prospectuses, in the light of the circumstances in which they were made) not misleading. 

     b. The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to a Registration Statement and the prospectus used in connection with such Registration
Statement, which prospectus is to be filed pursuant to Rule 424 promulgated under the 1933 Act, as may be necessary to keep such Registration Statement effective at all times during the Registration Period, and, during such period, comply with the
provisions of the 1933 Act with respect to the disposition of all Registrable Securities of the Company covered by such Registration Statement until such time as all of such Registrable Securities shall have been disposed of in accordance with the
intended methods of disposition by the seller or sellers thereof as set forth in such Registration Statement. In the case of amendments and supplements to a Registration Statement which are required to be filed pursuant to this Agreement (including
pursuant to this Section 3(b)) by reason of the Company filing a report on Form 10-QSB, Form 10-KSB or any analogous report under the Securities Exchange Act of 1934, as amended (the "1934 Act"), the Company shall have incorporated such
report by reference into such Registration Statement, if applicable, or shall file such amendments or supplements with the SEC on the same day on which the 1934 Act report is filed which created the requirement for the Company to amend or supplement
such Registration Statement. 

     c. The Company shall (A) permit Legal Counsel to review and comment upon (i) a Registration Statement at least five (5) Business Days prior to its filing with the SEC and (ii) all amendments and supplements to all
Registration Statements (except for Annual Reports on Form 10-KSB, and Reports on Form 10-QSB and any similar or successor reports) within a reasonable number of days prior to their filing with the SEC, and (B) not file any Registration Statement or
amendment or supplement thereto in a form to which Legal Counsel reasonably objects.  The Company shall not submit a request for acceleration of the effectiveness of a Registration Statement or any amendment or supplement thereto without the prior
approval of Legal Counsel, which consent shall not be unreasonably withheld.  The Company shall furnish to Legal Counsel, without charge, (i) copies of any correspondence from 

the SEC or the staff of the SEC to the Company or its representatives relating to any Registration Statement, (ii) promptly after the same is prepared and filed with the SEC, one copy of any Registration Statement and any amendment(s) thereto,
including financial statements and schedules, all documents incorporated therein by reference, if requested by an Investor, and all exhibits and (iii) upon the effectiveness of any Registration Statement, one copy of the prospectus included in such
Registration Statement and all amendments and supplements thereto. The Company shall reasonably cooperate with Legal Counsel in performing the Company's obligations pursuant to this Section 3. 

     d. The Company shall furnish to each Investor whose Registrable Securities are included in any Registration Statement, without charge, (i) promptly after the same is prepared and filed with the SEC, at least one copy of
such Registration Statement and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein by reference, if requested by an Investor, all exhibits and each preliminary prospectus, (ii) upon the
effectiveness of any Registration Statement, ten (10) copies of the prospectus included in such Registration Statement and all amendments and supplements thereto (or such other number of copies as such Investor may reasonably request) and (iii) such
other documents, including copies of any preliminary or final prospectus, as such Investor may reasonably request from time to time in order to facilitate the disposition of the Registrable Securities owned by such Investor. 

     e. The Company shall use its best efforts to (i) register and qualify, unless an exemption from registration and qualification applies, the resale by Investors of the Registrable Securities covered by a Registration
Statement under such other securities or "blue sky" laws of all applicable jurisdictions in the United States, (ii) prepare and file in those jurisdictions, such amendments (including post-effective amendments) and supplements to such registrations
and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) take such other actions as may be necessary to maintain such registrations and qualifications in effect at all times during the
Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a
condition thereto to (x) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(e), (y) subject itself to general taxation in any such jurisdiction, or (z) file a general consent to
service of process in any such jurisdiction. The Company shall promptly notify Legal Counsel and each Investor who holds Registrable Securities of the receipt by the Company of any notification with respect to the suspension of the registration or
qualification of any of the Registrable Securities for sale under the securities or "blue sky" laws of any jurisdiction in the United States or its receipt of actual notice of the initiation or threatening of any proceeding for such purpose. 

     f. The Company shall notify Legal Counsel and each Investor in writing of the happening of any event, as promptly as practicable after becoming aware of such event, as a result of which the prospectus included in a
Registration Statement, as then in effect, includes an untrue statement of a material fact or omission 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 (provided that in no event shall such notice contain any material, nonpublic information), and, subject to Section 3(r), promptly prepare a supplement or 

amendment to such Registration Statement to correct such untrue statement or omission, and deliver ten (10) copies of such supplement or amendment to Legal Counsel and each Investor (or such other number of copies as Legal Counsel or such Investor
may reasonably request). The Company shall also promptly notify Legal Counsel and each Investor in writing (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed, and when a Registration Statement or any
post-effective amendment has become effective (notification of such effectiveness shall be delivered to Legal Counsel and each Investor by facsimile on the same day of such effectiveness and by overnight mail), (ii) of any request by the SEC for
amendments or supplements to a Registration Statement or related prospectus or related information, and (iii) of the Company's reasonable determination that a post-effective amendment to a Registration Statement would be appropriate. 

     g. The Company shall use its best efforts to prevent the issuance of any stop order or other suspension of effectiveness of a Registration Statement, or the suspension of the qualification of any of the Registrable
Securities for sale in any jurisdiction and, if such an order or suspension is issued, to obtain the withdrawal of such order or suspension at the earliest possible moment and to notify Legal Counsel and each Investor who holds Registrable
Securities being sold of the issuance of such order and the resolution thereof or its receipt of actual notice of the initiation or threat of any proceeding for such purpose. 

     h. If any Investor is required under applicable securities laws to be described in the Registration Statement as an underwriter, at the reasonable request of such Investor, the Company shall furnish to such Investor, on
the date of the effectiveness of the Registration Statement and thereafter from time to time on such dates as an Investor may reasonably request (i) a letter, dated such date, from the Company's independent certified public accountants in form and
substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the Investors, and (ii) an opinion, dated as of such date, of counsel representing the Company for
purposes of such Registration Statement, in form, scope and substance as is customarily given in an underwritten public offering, addressed to the Investors. 

     i. Upon the request of any Investor in connection with such Investor's due diligence requirements, if any, the Company shall make available for inspection by (i) any Investor, (ii) Legal Counsel and (iii) one firm of
accountants or other agents retained by the Investors (collectively, the "Inspectors"), all pertinent financial and other records, and pertinent corporate documents and properties of the Company (collectively, the "Records"), as shall
be reasonably deemed necessary by each Inspector, and cause the Company's officers, directors and employees to supply all information which any Inspector may reasonably request; provided, however, that each Inspector shall agree to hold in strict
confidence and shall not make any disclosure (except to an Investor) or use of any Record or other information which the Company determines in good faith to be confidential, and of which determination the Inspectors are so notified, unless (a) the
disclosure of such Records is necessary to avoid or correct a misstatement or omission in any Registration Statement or is otherwise required under the 1933 Act, (b) the release of such Records is ordered pursuant to a final, non-appealable subpoena
or order from a court or government body of competent jurisdiction, or (c) the information in such Records has been made generally available to the public other than by disclosure in violation of this or any other agreement of which the Inspector
has knowledge. Each Investor agrees that it 

shall, upon learning that disclosure of such Records is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to the Company and allow the Company, at its expense, to undertake appropriate
action to prevent disclosure of, or to obtain a protective order for, the Records deemed confidential. Nothing herein (or in any other confidentiality agreement between the Company and any Investor) shall be deemed to limit the Investors' ability to
sell Registrable Securities in a manner which is otherwise consistent with applicable laws and regulations. 

     j. The Company shall hold in confidence and not make any disclosure of information concerning an Investor provided to the Company unless (i) disclosure of such information is necessary to comply with federal or state
securities laws, (ii) the disclosure of such information is necessary to avoid or correct a misstatement or omission in any Registration Statement, (iii) the release of such information is ordered pursuant to a subpoena or other final,
non-appealable order from a court or governmental body of competent jurisdiction, or (iv) such information has been made generally available to the public other than by disclosure in violation of this Agreement or any other agreement. The Company
agrees that it shall, upon learning that disclosure of such information concerning an Investor is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt written notice to such Investor and allow
such Investor, at the Investor's expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information. 

     k. The Company shall use its best efforts either to (i) cause all of the Registrable Securities covered by a Registration Statement to be listed on the Principal Market or each securities exchange on which securities of
the same class or series issued by the Company are then listed, if any, if the listing of such Registrable Securities is then permitted under the rules of such exchange.  The Company shall pay all fees and expenses in connection with satisfying its
obligation under this Section 3(k). 

     l. The Company shall cooperate with the Investors who hold Registrable Securities being offered and, to the extent applicable, facilitate the timely preparation and delivery of certificates (not bearing any restrictive
legend) representing the Registrable Securities to be offered pursuant to a Registration Statement and enable such certificates to be in such denominations or amounts, as the case may be, as the Investors may reasonably request and registered in
such names as the Investors may request. 

     m. If requested by an Investor, the Company shall (i) as soon as practicable incorporate in a prospectus supplement or post-effective amendment such information as an Investor reasonably requests to be included therein
relating to the sale and distribution of Registrable Securities, including, without limitation, information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the
offering of the Registrable Securities to be sold in such offering; (ii) as soon as practicable make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such
prospectus supplement or post-effective amendment; and (iii) as soon as practicable, supplement or make amendments to any Registration Statement if reasonably requested by an Investor holding any Registrable Securities. 

     n. The Company shall use its best efforts to cause the Registrable Securities covered by a Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary
to consummate the disposition of such Registrable Securities. 

     o. The Company shall make generally available to its security holders as soon as practical, but not later than ninety (90) days after the close of the period covered thereby, an earnings statement (in form complying
with, and in the manner provided by, the provisions of Rule 158 under the 1933 Act) covering a twelve-month period beginning not later than the first day of the Company's fiscal quarter next following the effective date of a Registration Statement.

     p. The Company shall otherwise use its best efforts to comply with all applicable rules and regulations of the SEC in connection with any registration hereunder. 

     q. Within two (2) Business Days after a Registration Statement which covers Registrable Securities is ordered effective by the SEC, the Company shall deliver, and shall cause legal counsel for the Company to deliver, to
the transfer agent for such Registrable Securities (with copies to the Investors whose Registrable Securities are included in such Registration Statement) confirmation that such Registration Statement has been declared effective by the SEC in the
form attached hereto as Exhibit A. 

     r. Notwithstanding anything to the contrary herein, at any time after the Effective Date, the Company may delay the disclosure of material, non-public information concerning the Company the disclosure of which at the
time is not, in the good faith opinion of the Board of Directors of the Company and its counsel, in the best interest of the Company and, in the opinion of counsel to the Company, otherwise required (a "Grace Period"); provided, that the
Company shall promptly (i) notify the Investors in writing of the existence of material, non-public information giving rise to a Grace Period (provided that in each notice the Company will not disclose the content of such material, non-public
information to the Investors) and the date on which the Grace Period will begin, and (ii) notify the Investors in writing of the date on which the Grace Period ends; and, provided further, that no Grace Period shall exceed fifteen (15) consecutive
days and during any three hundred sixty five (365) day period such Grace Periods shall not exceed an aggregate of forty (40) days and the first day of any Grace Period must be at least five (5) trading days after the last day of any prior Grace
Period (each, an "Allowable Grace Period").  For purposes of determining the length of a Grace Period above, the Grace Period shall begin on and include the date the Investors receive the notice referred to in clause (i) and shall end on and
include the later of the date the Investors receive the notice referred to in clause (ii) and the date referred to in such notice. The provisions of Section 3(g) hereof shall not be applicable during the period of any Allowable Grace Period. Upon
expiration of the Grace Period, the Company shall again be bound by the first sentence of Section 3(f) with respect to the information giving rise thereto unless such material, non-public information is no longer applicable. Notwithstanding anything
to the contrary, the Company shall cause its transfer agent to deliver unlegended shares of Common Stock to a transferee of an Investor in accordance with the terms of the Securities Purchase Agreement in connection with any sale of Registrable
Securities with respect to which an Investor has entered into a contract for sale, and delivered a copy of the prospectus included as part of the applicable Registration Statement (unless an 

exemption from such prospectus delivery requirements exists), prior to the Investor's receipt of the notice of a Grace Period and for which the Investor has not yet settled.

     s. The Company shall make any filing as may be required by NASD Rule 2710 in connection with the offering under any Registration Statement of the applicable Registrable Securities and shall make any such filing
concurrently with its initial filing of such Registration Statement with the SEC.

     t. Until the twelve month anniversary of the later to occur of (i) the Initial Effective Date and (ii) the Additional Effective Date, the Company shall not enter into any Subsequent Placement (as defined in the
Securities Purchase Agreement) where such Subsequent Placement provides for registration rights (including piggy-back registration right) to any one or more of the investors in such Subsequent Placement, without the prior written consent of the
Required Holders. 

     u. From the date hereof until the date that is six (6) months following the later to occur of (i) the Initial Effective Date and (ii) the Additional Effective Date, the Company will not, directly or indirectly, file any
registration statement (other than on Form S-8 or the filing of any post-effective amendments filed solely for the purpose of updating financial or other information in any registration statement of the Company that has been declared effective by
the SEC prior to the date of this Agreement) with the SEC other than the Registration Statement.

4. Obligations of the Investors. 

     a. At least five (5) Business Days prior to the first anticipated filing date of a Registration Statement, the Company shall notify each Investor in writing of the information the Company requires from each such
Investor if such Investor elects to have any of such Investor's Registrable Securities included in such Registration Statement.  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 a particular Investor that such Investor shall furnish to the Company such information regarding itself, the Registrable Securities held by it and the intended method of disposition of the
Registrable Securities held by it as shall be reasonably required to effect the effectiveness of the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably
request.

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

     c. Each Investor agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3(g) or the first sentence of 3(f), such Investor will immediately discontinue
disposition of Registrable Securities pursuant to any Registration Statement(s) covering such Registrable Securities until such 

Investor's receipt of the copies of the supplemented or amended prospectus contemplated by Section 3(g) or the first sentence of 3(f) or receipt of notice that no supplement or amendment is required. Notwithstanding anything to the contrary, the
Company shall cause its transfer agent to deliver unlegended shares of Common Stock to a transferee of an Investor in accordance with the terms of the Securities Purchase Agreement in connection with any sale of Registrable Securities with respect
to which an Investor has entered into a contract for sale prior to the Investor's receipt of a notice from the Company of the happening of any event of the kind described in Section 3(g) or the first sentence of 3(f) and for which the Investor has
not yet settled. 

     d. Each Investor covenants and agrees that it will comply with the prospectus delivery requirements of the 1933 Act as applicable to it or an exemption therefrom in connection with sales of Registrable Securities
pursuant to the Registration Statement. 

5. Expenses of Registration. 

     All reasonable expenses, other than underwriting discounts and commissions, incurred in connection with registrations, filings or qualifications pursuant to Sections 2 and 3, including, without limitation, all
registration, listing and qualifications fees, printers and accounting fees, and fees and disbursements of counsel for the Company shall be paid by the Company. The Company shall also reimburse the Investors for the fees and disbursements of Legal
Counsel in connection with registration, filing or qualification pursuant to Sections 2 and 3 of this Agreement which amount shall be limited to $20,000. 

6. Indemnification. 

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

     a. To the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend each Investor, the directors, officers, members, partners, employees, agents, representatives of, and
each Person, if any, who controls any Investor within the meaning of the 1933 Act or the 1934 Act (each, an "Indemnified Person"), against any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, reasonable
attorneys' fees, amounts paid in settlement or expenses, joint or several, (collectively, "Claims") incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or appeal taken from the
foregoing by or before any court or governmental, administrative or other regulatory agency, body or the SEC, whether pending or threatened, whether or not an indemnified party is or may be a party thereto ("Indemnified Damages"), to which
any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in a
Registration Statement or any post-effective amendment thereto or in any filing made in connection with the qualification of the offering under the securities or other "blue sky" laws of any jurisdiction in which Registrable Securities are offered
("Blue Sky Filing"), or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material
fact contained in any preliminary prospectus if used prior to the effective date of such Registration 

Statement, or contained in the final prospectus (as amended or
supplemented, if the Company files any amendment thereof or supplement thereto
with the SEC) or the omission or alleged omission to state therein any material
fact necessary to make the statements made therein, in the light of the
circumstances under which the statements therein were made, not misleading,
(iii) any violation or alleged violation by the Company of the 1933 Act, the
1934 Act, any other law, including, without limitation, any state securities
law, or any rule or regulation thereunder relating to the offer or sale of the
Registrable Securities pursuant to a Registration Statement or (iv) any
violation of this Agreement (the matters in the foregoing clauses (i) through
(iv) being, collectively, "Violations"). Subject to Section 6(c), the
Company shall reimburse the Indemnified Persons, promptly as such expenses are
incurred and are due and payable, for any legal fees or other reasonable
expenses incurred by them in connection with investigating or defending any such
Claim. Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 6(a): (i) shall not apply to
a Claim by an Indemnified Person arising out of or based upon a Violation which
occurs in reliance upon and in conformity with information furnished in writing
to the Company by such Indemnified Person for such Indemnified Person expressly
for use in connection with the preparation of the Registration Statement or any
such amendment thereof or supplement thereto, if such prospectus was timely made
available by the Company pursuant to Section 3(d) and (ii) shall not be
available to the extent such Claim is based on a failure of the Investor to
deliver or to cause to be delivered the prospectus made available by the
Company, including a corrected prospectus, if such prospectus or corrected
prospectus was timely made available by the Company pursuant to Section 3(d);
and (iii) shall not apply to amounts paid in settlement of any Claim if such
settlement is effected without the prior written consent of the Company, which
consent shall not be unreasonably withheld or delayed. Such indemnity shall
remain in full force and effect regardless of any investigation made by or on
behalf of the Indemnified Person and shall survive the transfer of the
Registrable Securities by the Investors pursuant to Section 9. 

     b. In connection with any
Registration Statement in which an Investor is participating, each such Investor
agrees to severally and not jointly indemnify, hold harmless and defend, to the
same extent and in the same manner as is set forth in Section 6(a), the Company,
each of its directors, each of its officers who signs the Registration Statement
and each Person, if any, who controls the Company within the meaning of the 1933
Act or the 1934 Act (each, an "Indemnified Party"), against any Claim or
Indemnified Damages to which any of them may become subject, under the 1933 Act,
the 1934 Act or otherwise, insofar as such Claim or Indemnified Damages arise
out of or are based upon any Violation, in each case to the extent, and only to
the extent, that such Violation occurs in reliance upon and in conformity with
written information furnished to the Company by such Investor expressly for use
in connection with such Registration Statement; and, subject to Section 6(c),
such Investor will reimburse any legal or other expenses reasonably incurred by
an Indemnified Party in connection with investigating or defending any such
Claim; provided, however, that the indemnity agreement contained in this Section
6(b) and the agreement with respect to contribution contained in Section 7 shall
not apply to amounts paid in settlement of any Claim if such settlement is
effected without the prior written consent of such Investor, which consent shall
not be unreasonably withheld or delayed; provided, further, however, that the
Investor shall be liable under this Section 6(b) for only that amount of a Claim
or Indemnified Damages as does not exceed the net proceeds to such Investor as a
result of the sale of Registrable Securities pursuant to such Registration
Statement. Such indemnity shall remain in full force and effect regardless of
any investigation made by or on 

behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by the Investors pursuant to Section 9.

     c. Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim,
such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying
party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the
indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the fees and expenses of not more than
one counsel for such Indemnified Person or Indemnified Party to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or
Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding.  In the case
of an Indemnified Person, legal counsel referred to in the immediately preceding sentence shall be selected by the Investors holding at least a majority in interest of the Registrable Securities included in the Registration Statement to which
the Claim relates.  The Indemnified Party or Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or Claim by the indemnifying party and shall furnish to the
indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such action or Claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person reasonably apprised at all
times as to the status of the defense or any settlement negotiations with respect thereto.  No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its prior written consent, provided, however,
that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the prior written consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter
into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party or Indemnified Person of a release from all liability in respect to such Claim or
litigation, and such settlement shall not include any admission as to fault on the part of the Indemnified Party.  Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party
or Indemnified Person with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the
commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability to defend
such action. 

     d. The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Damages are
incurred. 

     e. The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or Indemnified Person against the indemnifying party or others, and (ii) any
liabilities the indemnifying party may be subject to pursuant to the law. 

7. Contribution. 

     To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be
liable under Section 6 to the fullest extent permitted by law; provided, however, that:  (i) no Person involved in the sale of Registrable Securities which Person is guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
1933 Act) in connection with such sale shall be entitled to contribution from any Person involved in such sale of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of Registrable
Securities shall be limited in amount to the net amount of proceeds received by such seller from the sale of such Registrable Securities pursuant to such Registration Statement. 

8. Reports Under the 1934 Act.

     With a view to making available to the Investors the benefits of Rule 144 promulgated under the 1933 Act or any other similar rule or regulation of the SEC that may at any time permit the Investors to sell securities of
the Company to the public without registration ("Rule 144"), the Company agrees to: 

     a. make and keep public information available, as those terms are understood and defined in Rule 144; 

     b. file with the SEC in a timely manner all reports and other documents required of the Company under the 1933 Act and the 1934 Act so long as the Company remains subject to such requirements and the filing of such
reports and other documents is required for the applicable provisions of Rule 144; and 

     c. furnish to each Investor so long as such Investor owns Registrable Securities, promptly upon request, (i) a written statement by the Company, if true, that it has complied with the reporting requirements of Rule 144,
the 1933 Act and the 1934 Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the
Investors to sell such securities pursuant to Rule 144 without registration. 

9. Assignment of Registration Rights.

     The rights under this Agreement shall be automatically assignable by the Investors to any transferee of all or any portion of such Investor's Registrable Securities if: (i) the Investor agrees in writing with the
transferee or assignee to assign such rights, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment; (ii) the Company is, within a reasonable time after such transfer or assignment, furnished with
written notice of (a) the name and address of such transferee or assignee, and (b) the securities 

with respect to which such registration rights are being
transferred or assigned; (iii) immediately following such transfer or assignment
the further disposition of such securities by the transferee or assignee is
restricted under the 1933 Act and applicable state securities laws; (iv) at or
before the time the Company receives the written notice contemplated by clause
(ii) of this sentence the transferee or assignee agrees in writing with the
Company to be bound by all of the provisions contained herein; and (v) such
transfer shall have been made in accordance with the applicable requirements of
the Securities Purchase Agreement. 

10. Amendment of Registration Rights. 

     Provisions of this Agreement may
be amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of the Company and the Required Holders. Any amendment or waiver
effected in accordance with this Section 10 shall be binding upon each Investor
and the Company. No such amendment shall be effective to the extent that it
applies to less than all of the holders of the Registrable Securities. No
consideration shall be offered or paid to any Person to amend or consent to a
waiver or modification of any provision of any of this Agreement unless the same
consideration also is offered to all of the parties to this Agreement. 

11. Miscellaneous. 

     a. A Person is deemed to be a
holder of Registrable Securities whenever such Person owns or is deemed to own
of record such Registrable Securities. If the Company receives conflicting
instructions, notices or elections from two or more Persons with respect to the
same Registrable Securities, the Company shall act upon the basis of
instructions, notice or election received from the such record owner of such
Registrable Securities. 

     b. Any notices, consents, waivers
or other communications required or permitted to be given under the terms of
this Agreement must be in writing and will be deemed to have been delivered: (i)
upon receipt, when delivered personally; (ii) upon receipt, when sent by
facsimile (provided confirmation of transmission is mechanically or

laws of any jurisdictions other than 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, 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 brought in an inconvenient forum or that the
venue of such suit, action or proceeding is improper. Each party hereby
irrevocably waives personal service of process and consents to process being

party at the address for such 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. If any provision of this
Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity
or unenforceability shall not affect the validity or enforceability of the
remainder of this Agreement in that jurisdiction or the validity or
enforceability of any provision of this Agreement in any other jurisdiction.
EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO
REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN

Re: Solar Enertech Corp. 

Ladies and Gentlemen: 

     [We are][I am] counsel to Solar
Enertech Corp., a Nevada corporation (the "Company"), and have
represented the Company in connection with that certain Securities Purchase
Agreement (the "Securities Purchase Agreement") entered into by and among
the Company and the buyers named therein (collectively, the "Holders")
pursuant to which the Company issued to certain of the Holders (i) Series A
convertible notes (the "Notes") convertible into the Company's common
stock, par value $0.001 per share (the "Common Stock) and (ii) Series A
warrants exercisable for shares of Common Stock (the "Warrants").
Pursuant to the Securities Purchase Agreement, the Company also has entered into
a Registration Rights Agreement with the Holders of the Notes and Warrants (the
"Registration Rights Agreement") pursuant to which the Company agreed,
among other things, to register the Registrable Securities (as defined in the
Registration Rights Agreement), including the shares of Common Stock issuable
upon conversion of the Notes and the shares of Common Stock issuable upon
exercise of the Warrants, under the Securities Act of 1933, as amended (the
"1933 Act"). In connection with the Company's obligations under the
Registration Rights Agreement, on _______________, 2007, the Company filed a
Registration Statement on Form SB-2 (File No. 333-_____________) (the
"Registration Statement") with the Securities and Exchange Commission
(the "SEC") relating to the Registrable Securities which names each of
the Holders of Notes and Warrants as a selling stockholder thereunder. 

     In connection with the foregoing,
[we][I] advise you that a member of the SEC's staff has advised [us][me] by
telephone that the SEC has entered an order declaring the Registration Statement
effective under the 1933 Act at [ENTER TIME OF EFFECTIVENESS] on
[ENTER DATE OF EFFECTIVENESS] and [we][I] have no knowledge, after
telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement. 

     This letter shall serve as our
standing instruction to you that the shares of Common Stock are freely
transferable by the Holders of Notes and Warrants pursuant to the 

1 

Registration Statement. You need not require further letters

EXHIBIT B 

SELLING STOCKHOLDERS 

     The shares of Common Stock being
offered by the selling stockholders are shares of common stock issuable upon
conversion of the convertible notes and upon exercise of the warrants. For
additional information regarding the issuance of those convertible notes and
warrants, see "Private Placement of Convertible Notes and Warrants" above. We
are registering the shares of Common Stock in order to permit the selling
stockholders to offer the shares for resale from time to time. Except for the
ownership of the Convertible Notes and Warrants issued pursuant to the
Securities Purchase Agreement, the selling stockholders have not had any
material relationship with us within the past three years. 

     The table below lists the selling
stockholders and other information regarding the beneficial ownership of the
shares of Common Stock by each of the selling stockholders. The second column
lists the number of shares of Common Stock beneficially owned by each selling
stockholder, based on its ownership of the convertible notes and warrants, as of
________, 200_, assuming conversion of all convertible notes and exercise of the
warrants held by the selling stockholders on that date, without regard to any
limitations on conversions or exercise. 

     The third column lists the shares
of Common Stock being offered by this prospectus by each selling stockholder.

     In accordance with the terms of a
registration rights agreement among the Company and the selling stockholders,
this prospectus generally covers the resale of at least 120% of the sum of (i)
the number of shares of Common Stock issuable upon conversion of the convertible
notes as of the trading day immediately preceding the date the registration
statement is initially filed with the SEC, (ii) the shares of common stock
previously issued and (iii) the number of shares of Common Stock issuable upon
exercise of the related warrants as of the trading day immediately preceding the
date the registration statement is initially filed with the SEC. Because
the conversion price of the convertible notes and the exercise price of the
warrants may be adjusted, the number of shares that will actually be issued may
be more or less than the number of shares being offered by this prospectus. The
fourth column assumes the sale of all of the shares offered by the selling
stockholders pursuant to this prospectus. 

     Under the terms of the
convertible notes and the warrants, a selling stockholder may not convert the
convertible notes or exercise the warrants to the extent such conversion or
exercise would cause such selling stockholder, together with its affiliates, to
beneficially own a number of shares of Common Stock which would exceed
[9.99][4.99]% of our then outstanding shares of Common Stock following such
conversion or exercise, excluding for purposes of such determination shares of
Common Stock issuable upon conversion of the convertible notes which have not
been converted and upon exercise of the warrants which have not been exercised.
The number of shares in the second column does not reflect this limitation. The
selling stockholders may sell all, some or none of their shares in this
offering. See "Plan of Distribution."

PLAN OF DISTRIBUTION 

     We are registering the shares of
common stock issuable upon conversion of the convertible notes and upon exercise
of the warrants to permit the resale of these shares of Common Stock by the
holders of the convertible notes and warrants from time to time after the date
of this prospectus. We will not receive any of the proceeds from the sale by the
selling stockholders of the shares of Common Stock. We will bear all fees and
expenses incident to our obligation to register the shares of Common Stock. 

     The selling stockholders may sell
all or a portion of the shares of Common Stock beneficially owned by them and
offered hereby from time to time directly or through one or more underwriters,
broker-dealers or agents. If the shares of Common Stock are sold through
underwriters or broker-dealers, the selling stockholders will be responsible for
underwriting discounts or commissions or agent's commissions. The shares of
Common Stock may be sold in one or more transactions at fixed prices, at
prevailing market prices at the time of the sale, at varying prices determined
at the time of sale, or at negotiated prices. These sales may be effected in
transactions, which may involve crosses or block transactions,

	
  on any national securities exchange or quotation service on which the
  securities may be listed or quoted at the time of sale; 

  
	
  in the over-the-counter market; 

  
	
  in transactions otherwise than on these exchanges or systems or in the
  over-the- counter market; 

  
	
  through the writing of options, whether such options are listed on an
  options exchange or otherwise; 

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

  
	
  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; 

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

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

  
	
  privately negotiated transactions; 

  
	
  short sales; 

  
	
  sales pursuant to Rule 144; 

1 

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

  
	
  a combination of any such methods of sale; and 

  
	
  any other method permitted pursuant to applicable law. 

     If the selling stockholders
effect such transactions by selling shares of Common Stock to or through
underwriters, broker-dealers or agents, such underwriters, broker-dealers or
agents may receive commissions in the form of discounts, concessions or
commissions from the selling stockholders or commissions from purchasers of the
shares of Common Stock for whom they may act as agent or to whom they may sell
as principal (which discounts, concessions or commissions as to particular
underwriters, broker-dealers or agents may be in excess of those customary in
the types of transactions involved). In connection with sales of the shares of
Common Stock or otherwise, the selling stockholders may enter into hedging
transactions with broker-dealers, which may in turn engage in short sales of the
shares of Common Stock in the course of hedging in positions they assume. The
selling stockholders may also sell shares of Common Stock short and deliver
shares of Common Stock covered by this prospectus to close out short positions
and to return borrowed shares in connection with such short sales. The selling
stockholders may also loan or pledge shares of Common Stock to broker-dealers
that in turn may sell such shares. 

     The selling stockholders may
pledge or grant a security interest in some or all of the convertible notes or
warrants or 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 pursuant to this
prospectus or any amendment to this prospectus under Rule 424(b)(3) or other
applicable provision of the Securities Act of 1933, as amended, amending, if
necessary, 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 and donate the shares of Common Stock
in other circumstances in which case the transferees, donees, pledgees or other
successors in interest will be the selling beneficial owners for purposes of
this prospectus. 

     The selling stockholders and any
broker-dealer participating in the distribution of the shares of Common Stock
may be deemed to be "underwriters" within the meaning of the Securities Act, and
any commission paid, or any discounts or concessions allowed to, any such
broker-dealer may be deemed to be underwriting commissions or discounts under
the Securities Act. At the time a particular offering of the shares of Common
Stock is made, a prospectus supplement, if required, will be distributed which
will set forth the aggregate amount of shares of Common Stock being offered and
the terms of the offering, including the name or names of any broker-dealers or
agents, any discounts, commissions and other terms constituting compensation
from the selling stockholders and any discounts, commissions or concessions
allowed or reallowed or paid to broker-dealers. 

     Under the securities laws of some
states, the shares of Common Stock may be sold in such states only through
registered or licensed brokers or dealers. In addition, in some states the
shares of Common Stock may not be sold unless such shares have been registered
or qualified 

2 

for sale in such state or an exemption from registration or
qualification is available and is complied with. 

     There can be no assurance that
any selling stockholder will sell any or all of the shares of Common Stock
registered pursuant to the registration statement, of which this prospectus
forms a part. 

     The selling stockholders and any
other person participating in such distribution will be subject to applicable
provisions of the Securities Exchange Act of 1934, as amended, and the rules and
regulations thereunder, including, without limitation, Regulation M of the
Exchange Act, which may limit the timing of purchases and sales of any of the
shares of Common Stock by the selling stockholders and any other participating
person. Regulation M may also restrict the ability of any person engaged in the
distribution of the shares of Common Stock to engage in market-making activities
with respect to the shares of Common Stock. All of the foregoing may affect the
marketability of the shares of Common Stock and the ability of any person or
entity to engage in market-making activities with respect to the shares of
Common Stock. 

     We will pay all expenses of the
registration of the shares of Common Stock pursuant to the registration rights
agreement, estimated to be $[ ] in total, including, without limitation,
Securities and Exchange Commission filing fees and expenses of compliance with
state securities or "blue sky" laws; provided, however, that a selling
stockholder will pay all underwriting discounts and selling commissions, if any.
We will indemnify the selling stockholders against liabilities, including some
liabilities under the Securities Act, in accordance with the registration rights
agreements, or the selling stockholders will be entitled to contribution. We may
be indemnified by the selling stockholders against civil liabilities, including
liabilities under the Securities Act, that may arise from any written
information furnished to us by the selling stockholder specifically for use in
this prospectus, in accordance with the related registration rights agreement,
or we may be entitled to contribution. 

     Once sold under the registration
statement, of which this prospectus forms a part, the shares of Common Stock
will be freely tradable in the hands of persons other than our affiliates.

Form of Lock-Up Agreement 

Lock-Up Agreement 

March 7, 2007 

Solar Enertech Corp.
1600 Adams Drive 
Menlo Park,
California 94025 

Re: Lock-Up Agreement

Ladies and Gentlemen: 

     This letter agreement (this “Agreement”)
  relates to the private placement (the “Offering”) by Solar
  Enertech Corp., a Nevada corporation (the “Company”), of an
  aggregate of up to $13,300,000 principal amount of notes (“Notes”)
  and warrants (“Warrants”) to purchase shares of common stock
  of the Company. The Offering is governed by a Securities Purchase Agreement
  between the Company and the investors signatory thereto (“Investors”).

     In order to induce the Investors
to participate in the Offering, the undersigned hereby agrees that during the
period from the date hereof until and through the date that is one year after
the date on which the Securities and Exchange Commission declares the
registration statement covering the shares of common stock underlying the Notes
and Warrants sold in the Offering effective (the “Lock-Up Period”), the
undersigned: (a) will not, directly or indirectly, offer, sell, agree to offer
or sell, solicit offers to purchase, grant any call option or purchase any put
option with respect to, pledge, borrow or otherwise dispose of any Relevant
Security (as defined below), and (b) will not establish or increase any “put
equivalent position” or liquidate or decrease any “call equivalent position”
with respect to any Relevant Security (in each case within the meaning of
Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and
regulations promulgated thereunder), or otherwise enter into any swap,
derivative or other transaction or arrangement that transfers to another, in
whole or in part, any economic consequence of ownership of a Relevant Security,
whether or not such transaction is to be settled by delivery of Relevant
Securities, other securities, cash or other consideration. Notwithstanding the
foregoing, during the Lock-Up Period the undersigned may sell up to 100,000
shares of Common Stock during each ninety (90) day period commencing on the date
that is one hundred eighty (180) days after the date on which the Securities and
Exchange Commission declares the registration statement covering the shares of
common stock underlying the Notes and Warrants sold in the Offering effective.

     As used herein, the term
“Relevant Security” means any shares of Common Stock or other security of
the Company thereof that is convertible into, or exercisable or exchangeable for
shares of Common Stock or equity securities of the Company or that holds the
right to acquire any shares of Common Stock or equity securities of the Company
or any other such Relevant Security.

     The undersigned hereby authorizes
the Company during the Lock-Up Period to cause any transfer agent for the
Relevant Securities to decline to transfer, and to note stop transfer
restrictions on the stock register and other records relating to, Relevant
Securities for which the undersigned is the record holder and, in the case of
Relevant Securities for which the undersigned is the beneficial but not the
record holder, agrees during the Lock-Up Period to cause the record 

holder to cause the relevant transfer agent to decline to
transfer, and to note stop transfer restrictions on the stock register and other
records relating to, such Relevant Securities.

     The undersigned hereby represents
and warrants to the Placement Agent and the Company that the undersigned has
full power and authority to enter into this Agreement and that this Agreement
constitutes the legal, valid and binding obligation of the undersigned,
enforceable in accordance with its terms. Upon request, the undersigned will
execute any additional documents necessary in connection with enforcement
hereof. Any obligations of the undersigned shall be binding upon the successors
and assigns of the undersigned from the date first above written.

     This Agreement shall be governed
by and construed in accordance with the laws of the State of New York, without
regard to the conflicts of laws principles thereof. Delivery of a signed copy of
this letter by facsimile transmission shall be effective as delivery of the
original hereof.

Very truly yours,
