The Company has also agreed to grant to you an option (the "Option") to purchase up to an additional 862,500 shares of Common Stock, on the terms and for the purposes set forth in Section 1(b) (the "Option Shares"). The Firm Shares and the Option Shares are referred to collectively herein as the "Shares."

The Option may be exercised only to cover over-allotments in the sale of the Firm Shares by the Underwriter and may be exercised in whole or in part at any time (but not more than once) on or before the 30th day after the date of this Agreement upon written or telegraphic notice (the "Option Shares Notice") by the Underwriter to the Company no later than 12:00 p.m., New York City time, at least two and no more than five business days before the date specified for closing in the Option Shares Notice (the "Option Closing Date"), setting forth the aggregate number of Option Shares to be purchased and the time and date for such purchase.

(a) The Company meets the requirements for the use of Form S-3 and a registration statement (Registration No. 333-135474) on Form S-3 relating to the Shares, including a base prospectus relating to the Shares (the "Base Prospectus") and such amendments thereto as may have been required to the date of this Agreement, has been prepared by the Company under the provisions of the Securities Act of 1933, as amended (the "Act"), and the rules and regulations (collectively referred to as the "Rules and Regulations") of the Securities and Exchange Commission (the "Commission") thereunder, has been filed with the Commission, and has been declared effective by the Commission, and the offering of the Shares complies with Rule 415 under the Act. A final prospectus supplement to the Base Prospectus relating to the Shares and the offering thereof will be filed promptly by the Company with the Commission in accordance with Rule 424(b) of the Rules and Regulations (such final prospectus supplement, as so filed, the "Prospectus Supplement"). Such registration statement at any given time, including the amendments thereto to such time, the exhibits and any schedules thereto at such time, the documents otherwise deemed to be a part thereof or included therein by the Rules and Regulations (including Rule 430A or Rule 430B thereof), and any registration statement relating to the offering contemplated by this Agreement and filed pursuant to Rule 462(b) of the Rules and Regulations ("Rule 462(b)"), is herein called the "Registration Statement." The term "preliminary prospectus" means any preliminary prospectus (including any preliminary prospectus supplement) relating to the Shares and the offering thereof as first filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations ("Rule 424(b)"). The term "Prospectus" means the Base Prospectus together with the Prospectus Supplement, except that if such Base Prospectus is amended or supplemented on or prior to the date on which the Prospectus Supplement was first filed pursuant to Rule 424(b), the term "Prospectus" shall mean the Base Prospectus as so amended or supplemented and as supplemented by the Prospectus Supplement. Any reference herein to the Registration Statement, the Base Prospectus, a preliminary prospectus, the Prospectus Supplement, or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein, and any reference herein to the terms "amend," "amendment" or "supplement" with respect to the Registration Statement, the Base Prospectus, a preliminary prospectus, the Prospectus Supplement, or the Prospectus shall be deemed to

refer to and include the filing of any document under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), after the time the Registration Statement initially became effective (the "Effective Date") and the date of the Base Prospectus, any preliminary prospectus, the Prospectus Supplement, or the Prospectus, as the case may be, and deemed to be incorporated therein by reference. The term "Issuer Free Writing Prospectus" means any "issuer free writing prospectus," as defined in Rule 433 of the Rules and Regulations ("Rule 433"), relating to the Shares in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company's records pursuant to Rule 433(g).

(b) No order preventing or suspending the use of the Base Prospectus, any preliminary prospectus, the Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus has been issued by the Commission, and no stop order suspending the effectiveness of the Registration Statement (including any related registration statement filed pursuant to Rule 462(b)) or any post-effective amendment thereto has been issued, and no proceeding for that purpose has been initiated or threatened by the Commission. On the Effective Date, on the date the Base Prospectus, any preliminary prospectus, the Prospectus Supplement, or the Prospectus is first filed with the Commission pursuant to Rule 424(b) (if required), at all times during the period through and including the Closing Date and, if later, the Option Closing Date and when any post-effective amendment to the Registration Statement becomes effective or any amendment or supplement to the Prospectus is filed with the Commission, the Registration Statement and the Prospectus (as amended or as supplemented if the Company shall have filed with the Commission any amendment or supplement thereto), including the financial statements included or incorporated by reference in the Prospectus, did and will comply with all applicable provisions of the Act, the Exchange Act, the rules and regulations under the Exchange Act (the "Exchange Act Rules and Regulations"), and the Rules and Regulations and will contain all statements required to be stated therein in accordance with the Act, the Exchange Act, the Exchange Act Rules and Regulations, and the Rules and Regulations. As of the applicable effective date as to each part of the Registration Statement, no part of the Registration Statement, the Prospectus or any such amendment or supplement thereto did or will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading. At the Effective Date, the date the Base Prospectus or any amendment or supplement to the Base Prospectus, including any preliminary prospectus or the Prospectus Supplement, is filed with the Commission, the date of first use of any preliminary prospectus or the Prospectus Supplement, and the Closing Date and, if later, the Option Closing Date, the Prospectus did not and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

As of the Applicable Time, neither (x) the Issuer General Use Free Writing Prospectus(es) (as defined below) issued at or prior to the Applicable Time (as defined below), the Pricing Prospectus (as defined below) and the documents listed on Schedule I hereto, all considered together (collectively, the "General Disclosure Package"), nor (y) any individual Issuer Limited Use Free Writing Prospectus, when considered together with the General Disclosure Package, included any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

As used in this subsection and elsewhere in this Agreement:

"Pricing Prospectus" means the Base Prospectus, as amended or supplemented immediately prior to the Applicable Time, including any document incorporated by reference therein and any prospectus supplement deemed to be a part thereof. For purposes of this definition, information contained in a

form of prospectus that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430A or Rule 430B shall be considered to be included in the Pricing Prospectus only if the actual time that form of prospectus is filed with the Commission pursuant to Rule 424(b) is prior to the Applicable Time.

"Issuer General Use Free Writing Prospectus" means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors, as evidenced by its being specified in Schedule I hereto.

Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Shares or until any earlier date that the issuer notified or notifies Xxxxxxx & Company, LLC as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated by reference therein that has not been superseded or modified. If there occurs an event or development as a result of which the General Disclosure Package would include an untrue statement of a material fact or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will promptly notify the Underwriter so that any use of the General Disclosure Package may cease until it is amended or supplemented to correct untrue statement or omission.

The foregoing representations and warranties in this Section 3(b) do not apply to any statements or omissions made in reliance on and in conformity with information relating to the Underwriter furnished in writing to the Company by the Underwriter specifically for inclusion in the Registration Statement, the Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus or any amendment or supplement thereto. The Company acknowledges that the statements set forth in the fourth and eighth through twelfth paragraphs under the heading "Underwriting" in the Prospectus constitute the only information relating to the Underwriter furnished in writing to the Company by the Underwriter specifically for inclusion in the Registration Statement, the Prospectus Supplement, the Prospectus and any Issuer Free Writing Prospectus.

The Company and each of its Subsidiaries are corporations duly organized, validly existing and in good standing under the laws of their respective jurisdiction of incorporation. The Company and each of its Subsidiaries have full power and authority to conduct all the activities conducted by them, to own or lease all the assets owned or leased by them and to conduct their business as described in the Registration Statement, the Pricing Prospectus and the Prospectus. The Company and each of its Subsidiaries are duly licensed or qualified to do business and in good standing as foreign corporations in all jurisdictions in which the nature of the activities conducted by them or the character of the assets owned or leased by them make such license or qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not materially and adversely affect the Company and its Subsidiaries, taken as a whole, or their respective businesses, properties, business prospects, conditions (financial or other) or results of operations, taken as a whole (such effect is referred to herein as a "Material Adverse Effect"). All of the outstanding shares of capital stock of each Subsidiary have been duly authorized and validly issued and are fully paid and nonassessable, and owned by the Company free and clear of all claims, liens, charges and encumbrances; there are no securities outstanding that are convertible into or exercisable or exchangeable for capital stock of any Subsidiary. The Company and its Subsidiaries are not engaged in any discussions or a party to any agreement or understanding, written or oral, regarding the acquisition of an interest in any corporation, firm, partnership, joint venture, association or other entity where such discussions, agreements or understandings would require amendment to the Registration Statement pursuant to applicable securities laws. Complete and correct copies of the certificate of incorporation and of the by-laws of the Company and each of its Subsidiaries and all amendments thereto have been delivered to the Underwriter, and no changes therein will be made subsequent to the date hereof and prior to the Closing Date or, if later, the Option Closing Date.

The description of the capital stock of the Company incorporated by reference in the Registration Statement, the Pricing Prospectus and the Prospectus is complete and accurate in all respects. The Company does not have outstanding and, at the Closing Date and, if later, the Option Closing Date, will not have outstanding, any options to purchase, or any rights or warrants to subscribe for, or any securities or obligations convertible into, or any contracts or commitments to issue or sell, any shares of capital stock, or any such warrants, convertible securities or obligations. No further approval or authority of stockholders or the Board of Directors of the Company will be required for the issuance and sale of the Shares as contemplated herein. The certificates evidencing the Shares are in due and proper legal form and have been duly authorized for issuance by the Company.

(g) The financial statements and schedules included or incorporated by reference in the Registration Statement, the Pricing Prospectus or the Prospectus present fairly the financial condition of the Company and its consolidated Subsidiaries as of the respective dates thereof and the results of operations and cash flows of the Company and its consolidated Subsidiaries for the respective periods covered thereby, all in conformity with generally accepted accounting principles applied on a consistent basis throughout the entire period involved. No other financial statements or schedules of the Company are required by the Act, the Exchange Act, the Exchange Act Rules and Regulations or the Rules and Regulations to be included in the Registration Statement, the Pricing Prospectus or the Prospectus.

The Company and its Subsidiaries have valid, subsisting and enforceable leases for the properties described in the Pricing Prospectus and the Prospectus as leased by them. The Company and its Subsidiaries own or lease all such properties as are necessary to their operations as now conducted or as proposed to be conducted, except where the failure to so own or lease would not have a Material Adverse Effect.

Neither the Company nor any of its directors, officers or controlling persons has taken, directly or indirectly, any action designed, or that might reasonably be expected, to cause or result, under the Act or otherwise, in, or that has constituted, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares.

(u) The Company and each of its Subsidiaries have filed all federal, state, local and foreign income tax returns that have been required to be filed and have paid all taxes and assessments received by it to the extent that such taxes or assessments have become due. Neither the Company nor any of its Subsidiaries has any tax deficiency that has been or, to the best knowledge of the Company, might be asserted or threatened against it that could have a Material Adverse Effect.

(v) The Company and its Subsidiaries own or possess all authorizations, approvals, orders, licenses, registrations, other certificates and permits of and from all governmental regulatory officials and bodies, necessary to conduct their respective businesses as contemplated in the Pricing Prospectus and the Prospectus, except where the failure to own or possess all such authorizations, approvals, orders, licenses, registrations, other certificates and permits would not have a Material Adverse Effect. There is no proceeding pending or threatened (or any basis therefor known to the Company) that may cause any such authorization, approval, order, license, registration, certificate or permit to be revoked, withdrawn, cancelled, suspended or not renewed; and the Company and each of its Subsidiaries are conducting their respective businesses in compliance with all laws, rules and regulations applicable thereto (including, without limitation, all applicable federal, state and local environmental laws and regulations) except where such noncompliance would not have a Material Adverse Effect.

(w) The Company and each of its Subsidiaries maintain insurance of the types and in the amounts generally deemed adequate for their respective businesses, including, but not limited to, insurance covering real and personal property owned or leased by the Company and its Subsidiaries against theft, damage, destruction, acts of vandalism and all other risks customarily insured against, all of which insurance is in full force and effect.

(y) The books, records and accounts of the Company and its Subsidiaries accurately and fairly reflect, in reasonable detail, the transactions in, and dispositions of, the assets of, and the results of operations of, the Company and its Subsidiaries. The Company and each of its Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management's general or specific authorization, (ii) transactions are recorded as necessary to permit preparation of the Company's consolidated financial statements in accordance with generally accepted accounting principles and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management's general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company's internal control over financial reporting is effective and the Company is not aware of any material weaknesses in its internal control over financial reporting. Since the date of the latest audited financial statements incorporated by reference in the Pricing Prospectus and the Prospectus, there has been no change in the Company's internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

(z) The Company maintains disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act); such disclosure controls and procedures have been designed to ensure that material information relating to the Company and its Subsidiaries is made known to the Company's principal executive officer and principal financial officer by others within those entities; and such disclosure controls and procedures are effective.

4. Agreements of the Company. The Company covenants and agrees with the Underwriter as follows:

(a) The Company will not, either prior to the Applicable Time or thereafter during such period as the Prospectus is required by law to be delivered in connection with sales of the Shares by the Underwriter or a dealer, file any amendment or supplement to the Registration Statement, the Base Prospectus or the Prospectus, unless a copy thereof shall first have been submitted to the Underwriter within a reasonable period of time prior to the filing thereof and the Underwriter shall not have objected thereto in good faith.

(b) The Company will notify the Underwriter promptly, and will confirm such advice in writing, (i) when any amendment to the Registration Statement has been filed or becomes effective or any amendment or supplement to the Prospectus has been filed, (ii) of any request by the Commission for amendments or supplements to the Registration Statement or the Prospectus or for additional information, (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or preventing or suspending the use of the Base Prospectus, any preliminary prospectus, the Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus or the initiation of any proceedings for that purpose or the threat thereof, (iv) of the happening of any event during the period mentioned in the third sentence of Section 4(e) that in the judgment of the Company makes any statement made in the Registration Statement or the Prospectus untrue or that requires the making of any changes in the Registration Statement or the Prospectus in order to make the statements therein, in the light of the circumstances in which they are made, not misleading, and (v) of receipt by the Company or any representative or attorney of the Company of any other communication from the Commission relating to the Company, the Registration Statement, any preliminary prospectus or the Prospectus. If at any time the Commission shall issue any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of the Base Prospectus, any preliminary prospectus, the Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus, the Company will make reasonable efforts to obtain the withdrawal of such order at the earliest possible moment. If the Company has omitted any information from the Registration Statement pursuant to Rule 430A or Rule 430B of the Rules and Regulations, the Company will comply with the provisions of and make all requisite filings with the Commission pursuant to said Rule 430A or Rule 430B and notify the Underwriter promptly of all such filings.

(d) The Company will comply with all the provisions of any undertakings contained in the Registration Statement.

(e) So long as delivery of a prospectus by the Underwriter or a dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172 of the Rules and Regulations), the Company will deliver to the Underwriter, without charge, as many written and

electronic copies of each preliminary prospectus, the Base Prospectus, the Prospectus Supplement, the Prospectus and each Issuer Free Writing Prospectus as the Underwriter may reasonably request. The Company consents to the use of each preliminary prospectus, the Base Prospectus, the Prospectus Supplement, the Prospectus, each Issuer Free Writing Prospectus or any amendment or supplement thereto by the Underwriter and by all dealers to which the Shares may be sold, both in connection with the offering or sale of the Shares and for any period of time thereafter during which the Prospectus is required by law to be delivered in connection therewith.

The Company will not file any document under the Exchange Act or the Exchange Act Rules and Regulations before the termination of the offering of the Shares by the Underwriter, if such document would be deemed to be incorporated by reference into the Prospectus, that is not approved by the Underwriter after reasonable notice thereof. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement, the Pricing Prospectus or the Prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company will promptly notify the Underwriter and, if requested by the Underwriter, will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(k) The Company will apply the net proceeds from the offering and sale of the Shares to be sold by the Company in the manner set forth in the Pricing Prospectus and the Prospectus under "Use of Proceeds."

(m) During the period of 90 days after the date of the Prospectus, the Company will not file with the Commission or cause to become effective any registration statement relating to any securities of the Company without the prior written consent of Xxxxxxx & Company, LLC.

(a) The Company will indemnify and hold harmless the Underwriter, the directors, officers, employees and agents of the Underwriter and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all losses, claims, liabilities, expenses and damages (including any and all investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted), to which they, or any of them, may become subject under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus, the Base Prospectus, the Pricing Prospectus, the Prospectus or any amendment or supplement thereto or any Issuer Free Writing Prospectus or any "issuer information" filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, or the omission or alleged omission to state in such document a material fact required to be stated in it or necessary to make the statements in it not misleading in the light of the circumstances in which they

were made, or arise out of or are based in whole or in part on any inaccuracy in the representations and warranties of the Company contained herein or any failure of the Company to perform its obligations hereunder or under law in connection with the transactions contemplated hereby; provided, however, that the Company will not be liable to the extent that such loss, claim, liability, expense or damage arises from the sale of the Shares in the public offering to any person by the Underwriter and is based on an untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to the Underwriter furnished in writing to the Company by the Underwriter expressly for inclusion in the Registration Statement, any preliminary prospectus, the Base Prospectus, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus. The Company acknowledges that the statements set forth in the fourth and eighth through twelfth paragraphs under the heading "Underwriting" in the Pricing Prospectus and the Prospectus constitute the only information relating to the Underwriter furnished in writing to the Company by the Underwriter expressly for inclusion in the Registration Statement, any preliminary prospectus, the Base Prospectus, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus. This indemnity agreement will be in addition to any liability that the Company might otherwise have.

(b) The Underwriter will indemnify and hold harmless the Company, each director of the Company, each officer of the Company who signs the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to the Underwriter, as set forth in Section 7(a), but only insofar as losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to the Underwriter furnished in writing to the Company by the Underwriter expressly for use in the Registration Statement, any preliminary prospectus, the Base Prospectus, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus. The Company acknowledges that the statements set forth in the fourth and eighth through twelfth paragraphs under the heading "Underwriting" in the Pricing Prospectus and the Prospectus constitute the only information relating to the Underwriter furnished in writing to the Company by the Underwriter expressly for inclusion in the Registration Statement, any preliminary prospectus, the Base Prospectus, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus. This indemnity will be in addition to any liability that each Underwriter might otherwise have.

(c) Any party that proposes to assert the right to be indemnified under this Section 7 shall, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 7, notify each such indemnifying party in writing of the commencement of such action, enclosing with such notice a copy of all papers served, but the omission so to notify such indemnifying party will not relieve it from any liability that it may have to any indemnified party under the foregoing provisions of this Section 7 unless, and only to the extent that, such omission results in the loss of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (i) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (ii) the indemnified party has reasonably concluded (based on written advice of counsel) that there may be

legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (iii) a conflict or potential conflict exists (based on written advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party), or (iv) the indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly as they are incurred. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party. An indemnifying party will not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld or delayed).

(d) If the indemnification provided for in this Section 7 is applicable in accordance with its terms but for any reason is held to be unavailable to or insufficient to hold harmless an indemnified party under paragraphs (a), (b) and (c) of this Section 7 in respect of any losses, claims, liabilities, expenses and damages referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than the Underwriter, such as persons who control the Company within the meaning of the Act, officers of the Company who signed the Registration Statement and directors of the Company, who also may be liable for contribution) by such indemnified party as a result of such losses, claims, liabilities, expenses and damages in such proportion as shall be appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriter, on the other hand. The relative benefits received by the Company, on the one hand, and the Underwriter, on the other hand, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriter, in each case as set forth in the table on the cover page of the Prospectus. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company, on the one hand, and the Underwriter, on the other hand, with respect to the statements or omissions that resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriter, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as

a result of the loss claim, liability, expense or damage, or action in respect thereof, referred to above in this Section 7(d) shall be deemed to include, for purposes of this Section 7(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7(d), the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that the Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7(d), any person who controls a party to this Agreement within the meaning of the Act will have the same rights to contribution as that party, and each officer of the Company who signed the Registration Statement will have the same rights to contribution as the Company, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against any such party in respect of which a claim for contribution may be made under this Section 7(d), will notify any such party or parties from whom contribution may be sought, but the omission so to notify will not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 7(d). No party will be liable for contribution with respect to any action or claim settled without its written consent (which consent will not be unreasonably withheld).

(e) The indemnity and contribution agreements contained in this Section 7 and the representations and warranties of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of the Underwriter, (ii) acceptance of any of the Shares and payment therefor, or (iii) any termination of this Agreement.

8. Reimbursement of Certain Expenses. In addition to its other obligations under Section 7(a) of this Agreement, the Company hereby agrees to reimburse the Underwriter on a quarterly basis for all reasonable legal and other expenses incurred in connection with investigating or defending any claim, action, investigation, inquiry or other proceeding arising out of or based upon, in whole or in part, any statement or omission or alleged statement or omission, or any inaccuracy in the representations and warranties of the Company contained herein or failure of the Company to perform its or their respective obligations hereunder or under law, all as described in Section 7(a), notwithstanding the absence of a judicial determination as to the propriety and enforceability of the obligations under this Section 8 and the possibility that such payment might later be held to be improper; provided, however, that, to the extent any such payment is ultimately held to be improper, the persons receiving such payments shall promptly refund them.

9. Termination. The obligations of the Underwriter under this Agreement may be terminated at any time on or prior to the Closing Date (or, with respect to the Option Shares, on or prior to the Option Closing Date), by notice to the Company from the Underwriter, without liability on the part of the Underwriter to the Company if, prior to delivery and payment for the Firm Shares or Option Shares, as the case may be, in the sole judgment of the Underwriter, (i) trading in any of the equity securities of the Company shall have been suspended or limited by the Commission or by The NASDAQ Global Market, (ii) trading in securities generally on the New York Stock Exchange or The NASDAQ Global Market shall have been suspended or limited or minimum or maximum prices shall have been generally established on such exchanges, or additional material governmental restrictions, not in force on the date of this Agreement, shall have been imposed upon trading in securities generally by such exchange, by order of the Commission or any court or other governmental authority, or by the New York Stock Exchange or The NASDAQ Global Market, (iii) a general banking moratorium shall have been declared by either federal, New York State or California authorities or any material disruption of the securities settlement or clearance services in the United States shall have occurred, or

(iv) any material adverse change in the financial or securities markets in the United States or in political, financial or economic conditions in the United States, any outbreak or material escalation of hostilities involving the United States, a declaration of a national emergency or war by the United States, or other calamity or crisis, either within or outside the United States, shall have occurred, the effect of which is such as to make it, in the sole judgment of the Underwriter, impracticable or inadvisable to proceed with completion of the public offering or the delivery of and payment for the Shares.

If this Agreement is terminated pursuant to Section 10 hereof, the Company shall not be under any liability to the Underwriter except as provided in Sections 4(j), 7 and 8 hereof; but, if for any other reason the purchase of the Shares by the Underwriter is not consummated or if for any reason the Company shall be unable to perform its obligations hereunder, the Company will reimburse the Underwriter for all out-of-pocket expenses (including the fees, disbursements and other charges of counsel to the Underwriter) incurred by the Underwriter in connection with the offering of the Shares.

10. No Fiduciary Relationship. Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriter, the Company acknowledges and agrees that (i) the purchase and sale of the Shares pursuant to this Agreement (including the determination of the terms of the offering of the Shares) is an arm's-length commercial transaction between the Company and the Underwriter, (ii) in connection therewith and with the process leading to such transaction, the Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (iii) the Underwriter has not assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether the Underwriter has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement, (iv) the Underwriter and its affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and have no obligation to disclose or account to the Company for any of such differing interests, and (v) the Company has consulted its own legal, tax, accounting and financial advisors to the extent it deemed appropriate. The Company hereby agrees that it will not claim that the Underwriter has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

11. Miscellaneous. Notice given pursuant to any of the provisions of this Agreement shall be in writing and, unless otherwise specified, shall be mailed or delivered (a) if to the Company, at the office of the Company, 0000 Xxxxxxxxxx Xxxxx, Xxxxxxx, Xxxxxxxxxx 00000, Attention: Chief Executive Officer, with a copy to Xxxxx X.

Any notice under Section 9 or 10 may be made by telecopier or telephone, but if so made shall be subsequently confirmed in writing.

This Agreement has been and is made solely for the benefit of the Underwriter, the Company and the controlling persons, directors and officers referred to in Section 7, and their respective successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. The term "successors and assigns" as used in this Agreement shall not include a purchaser, as such purchaser, of Shares from the Underwriter.

This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed entirely within such State.

This Agreement may be signed in two or more counterparts with the same effect as if the signatures thereto and hereto were upon the same instrument.

In case any provision in this Agreement shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Each of the Company and the Underwriter hereby waives any right it may have to a trial by jury in respect of any claim based upon or arising out of this Agreement or the transactions contemplated hereby.

OPINION OF DLA PIPER US LLP

December 19, 2006

Xxxxxxx & Company, LLC
000 Xxxx Xxxxxx
Xxx Xxxx, XX 00000

Ladies and Gentlemen:

This opinion is furnished to you pursuant to Section 6(f) of the Underwriting Agreement dated December 14, 2006 (the "Agreement") by and between XXX, Inc., a Delaware corporation (the "Company"), and Xxxxxxx & Company, LLC (the "Underwriter"). We have served as outside general counsel for the Company, including in connection with the proceedings relating to the sale to the Underwriter of up to 6,612,500 shares of Common Stock of the Company (inclusive of the Firm Shares and the Option Shares) in accordance with the terms of the Agreement and in connection with the periodic reports and proxy statements filed with the Securities and Exchange Commission (the "Commission"). Capitalized terms used in this opinion, unless specifically defined in this opinion, have the meanings given them in the Agreement.

In connection with this opinion we have examined the following:

I.: All proceedings and documents made available to us by the Company relating to the incorporation of the Company under the laws of the State of Delaware, including the Certificate of Incorporation of the Company and all amendments and restatements thereof to the date hereof, the Bylaws of the Company as amended to the date hereof, and all proceedings made available to us by the Company relating to the sale of the Shares to the Underwriter pursuant to the Agreement;
II.: Registration Statement No. 333-135474, filed on June 29, 2006 with the Commission under the Securities Act of 1933, as amended (the "Act"), each preliminary prospectus together with its preliminary prospectus supplement, the Prospectus and all documents incorporated therein by reference;
III.: The Agreement;
IV.: The certificates of various corporate officers delivered by the Company to you pursuant to the Agreement on the date hereof;
V.: The certificates of certain state authorities and filing officers, copies of which are being delivered to you on the date hereof;
VI.: The Certificate of the Registrar and Transfer Company, as the transfer agent of the Company (the "Transfer Agent"), delivered to you on the date hereof;
VII.: Confirmation of wire transfers delivered by you on the date hereof as consideration for the sale of the Shares to be sold by the Company;
VIII.: The certificates or other documents delivered by or on behalf of the Company the Transfer Agent and you on the date hereof; and
IX.: Such instruments, corporate records, certificates and other documents as we have considered necessary or appropriate for the purposes of this opinion.

We are admitted to practice law only in the State of California, and we express no opinion concerning any law other than the law of the State of California, the corporation law of the State of Delaware and the federal law of the United States. With respect to the corporation law of the State of

Delaware, we have based our opinion solely upon our examination of such laws as reported in accepted unofficial compilations. Special rulings of Delaware authorities or opinions of Delaware counsel have not been obtained.

We have assumed the genuineness and authenticity of all documents submitted to us as originals, the conformity to originals of all documents submitted to us as copies, the due execution and delivery of the Agreement by the Underwriters and that the Agreement is a binding obligation of the Underwriters.

As to factual matters, we have relied solely upon certificates of public officials and of officers of the Company, oral and written representations made to us by officers of the Company, an inquiry of attorneys within our firm who have performed services for the Company and an examination of documents as set forth above; however, nothing has come to our attention which would lead us to believe that such certificates or representations are inaccurate.

Where we render an opinion "to our knowledge" or concerning an item "known to us" or our opinion otherwise refers to our knowledge, it is intended to indicate that during the course of our representation of the Company, no information that would give us current actual knowledge of the inaccuracy of such statement has come to the attention of those attorneys in this firm who have rendered or are rendering substantive legal services to the Company in the transactions contemplated by the Agreement. However, except as otherwise expressly indicated, we have not undertaken any independent investigation to determine the accuracy of such statement and any limited inquiry undertaken by us during the preparation of this opinion letter should not be regarded as such an investigation; no inference as to our knowledge of any matters bearing on the accuracy of any such statement should be drawn from the fact of our representation of the Company.

We call your attention to the fact that the Agreement states that it is governed by and construed in accordance with the laws of the State of New York and that we are not rendering any opinion with respect to New York law. We have not examined the question of what law would govern the interpretation or enforcement of the Agreement and our opinion is based on the assumption that the internal laws of the State of California and federal law would govern the provisions of the Agreement and the transactions contemplated thereby and that the laws of the State of New York are, in substance, identical to the laws of the State of California and federal law regarding the enforceability of the Agreement. We note that if the Agreement is not, in fact, legal, valid, binding and enforceable under the laws of the State of New York, the Agreement may not be enforced by a California court under applicable conflicts of law principles. We express no opinion with respect to any questions of choice of law, choice of venue or conflict of laws.

With respect to our opinion in Paragraph 1 that the Company is qualified to do business and is in good standing in all jurisdictions where it has employees or owns or leases property requires such qualification, we have relied solely upon written representations made to us by officers of the Company as to the jurisdictions in which the Company has employees or owns or leases property and certificates of public officials as to the Company's qualification and good standing.

With respect to our opinion in Paragraphs 2 and 3 that all issued and outstanding shares of the Company are fully paid, we have relied solely upon representations concerning the receipt by the Company of consideration for such shares made to us in certificates executed by officers of the Company.

With respect to our opinion in Paragraph 4 as to numbers of shares of Common Stock outstanding as disclosed in the Company's June 30, 2006 and October 31, 2006 balance sheets, we have relied solely on a certificate of the Transfer Agent.

With respect to our opinion in Paragraph 5, we have relied solely on an inquiry of officers of the Company concerning pending or threatened legal and governmental proceedings, oral and written

representations made to us by officers of the Company and an inquiry of attorneys within our firm who perform legal services for the Company.

With respect to our opinion in Paragraph 8(A) regarding laws applicable to the Company, we have not conducted any special investigation of statutes, laws, ordinances, rules or regulations and our opinion with respect thereto is limited to such California laws and United States statutes, laws, rules and regulations as in our experience are of general application. We have based our opinion on our experience with such laws as are typically applicable to the transactions of the type contemplated by the Agreement.

With respect to our opinion in Paragraph 8(B), and without limiting the paragraph above concerning our knowledge, our opinion is based only to our knowledge without any review of the Company's agreements or contracts (other than those filed with the Commission pursuant to Item 601 of Regulation S-K).

With respect to our opinion in Paragraph 8(C) concerning judgments, orders or decrees, we have relied solely on representations made to us by officers of the Company that there are no judgments, orders or decrees applicable to the Company or its subsidiaries and an inquiry of attorneys within our firm who perform legal services for the Company.

With respect to our opinion in Paragraph 9 regarding documents required to be described or referred to in the Registration Statement or Prospectus or filed as an exhibit to the Registration Statement, we have relied solely upon an inquiry of attorneys within our firm who have performed substantive legal services for the Company and written representations made to us by officers of the Company that the Company has informed us of all such transactions and has supplied us with copies of all agreements, franchises, contracts, leases and documents to which the Company is a party that are the types of contracts, leases or documents described in Items 404 and 601 of Regulation S-K, as promulgated under the Act by the Commission, and we have examined only those copies supplied to us by the Company.

With respect to our opinion in Paragraph 14 regarding no stop orders suspending the effectiveness of the Registration Statement, we have relied solely upon a telephone conversation on this date with the Commission.

We express no opinion with respect to:

A.: the availability of equitable remedies, including specific performance;
B.: the enforceability of the indemnification and contribution provisions of the Agreement;
C.: the effect of bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' rights generally;
D.: the effect on the enforceability of the Agreement of Sections 1667, 1668 and 1670.5 of the California Civil Code;
E.: compliance or noncompliance with the antifraud provisions of state or federal laws, rules and regulations concerning the issuance of securities (other than as set forth in paragraphs 4,5, 9, 10, 15 and 16 and the paragraphs following paragraph 16);
F.: the effects of general principles of equity, regardless of whether considered in proceedings in equity or at law, including, without limitation, concepts of materiality, good faith and fair dealing, and the availability of equitable remedies, including the rights to specific performance or injunctive relief;
G.: the effects of California or federal law or court decisions rendering unenforceable provisions (i) releasing or exonerating a party from liability, or limiting the liability of a party, for

wrongful or negligent acts or (ii) indemnifying a party, to the extent that the events giving rise to the indemnity arise in whole or in part from the wrongful or negligent acts of the indemnitee;

H.: the effects of California Civil Code Section 1717 and other applicable statutes and judicial decisions which provide, among other things, that a court may limit the granting of attorneys' fees to those attorneys' fees which are determined by the court to be reasonable and that attorneys' fees may be granted only to a prevailing party and that a contractual provision for attorneys' fees is deemed to extend to both parties (notwithstanding that such provision by its express terms benefits only one party);
I.: the effect of decisions by California courts admitting evidence extrinsic to a written agreement between the parties thereto as evidence that the parties intended a meaning contrary to that expressed by the parties in writing.
J.: the enforceability of any provisions requiring the parties to execute, in the future, additional instruments and documents;
K.: the enforceability of any provisions with respect to provisions relating to choice of laws or conflict of laws;
L.: the enforceability of the consent to service, jurisdiction, venue or forum of any claim, demand, action or cause of action arising under or related to the Agreement or the transactions contemplated therein; or
M.: the effect of California Civil Code Section 1698 and similar statutes and federal laws and judicial decisions (i) providing that oral modifications to a contract or waivers of contractual provisions may be enforceable, if the modification was performed, notwithstanding any express provision in the agreement that the agreement may only be modified or an obligation thereunder waived in writing, or (ii) creating an implied agreement from trade practices or course of conduct.

Subject to and in reliance upon the foregoing, it is our opinion as of the date hereof that:

1.: The Company is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation; has full corporate power and authority to conduct all the activities conducted by it, to own or lease all the assets owned or leased by it and to conduct its business as described in the Registration Statement and Prospectus; and is duly licensed or qualified to do business and is in good standing as a foreign corporation in each state in the United States in which the Company has employees or owns or leases real property.
2.: All of the outstanding shares of capital stock of the Company have been duly authorized and validly issued and are nonassessable and, to our knowledge, are fully paid and were issued pursuant to registration and qualification requirements, or exemptions from the registration and qualification requirements, of United States federal and applicable state securities laws, and were not issued in violation of or subject to any preemptive or similar rights.
3.: The Shares have been duly authorized and, when issued and paid for as contemplated by this Agreement, will be validly issued, fully paid and nonassessable. No preemptive or similar rights with respect to the Shares or the issue or sale thereof exist under the Company's certificate of incorporation and, to our knowledge, no such preemptive or similar rights otherwise exist.
4.: The authorized, issued and outstanding capital stock of the Company is as set forth in the Company's June 30, 2006 and October 31, 2006 balance sheets incorporated by reference into

the Registration Statement, the Pricing Prospectus and the Prospectus (except for subsequent issuances, if any, pursuant to this Agreement or pursuant to reservations, agreements, employee benefit plans or the exercise of convertible securities, options or warrants referred to in the Prospectus). To our knowledge, except as disclosed in or specifically contemplated by the Pricing Prospectus and the Prospectus, there are no outstanding options, warrants or other rights calling for the issuance of, and no commitments, plans or arrangements to issue, any shares of capital stock of the Company or any security convertible into or exchangeable or exercisable for capital stock of the Company. The description of the capital stock of the Company included and incorporated by reference in the Registration Statement, the Pricing Prospectus and the Prospectus conforms in all material respects to the terms thereof.

5.: To our knowledge, there are no legal or governmental proceedings pending or threatened to which the Company is a party or to which any of their respective properties is subject that are required to be described in the Registration Statement, the Pricing Prospectus or the Prospectus but are not so described.
6.: No consent, approval, authorization or order of, or any filing or declaration with, any court or governmental agency or body is required for the consummation by the Company of the transactions on its part contemplated under this Agreement, except such as have been obtained or made under the Act or the Rules and Regulations and such as may be required under state securities or Blue Sky laws or the by-laws and rules of the NASD in connection with the purchase and distribution by the Underwriter of the Shares.
7.: The Company has full corporate power and authority to enter into this Agreement. This Agreement has been duly authorized, executed and delivered by the Company.
8.: The execution and delivery of this Agreement, the compliance by the Company with all of the terms hereof and the consummation of the transactions contemplated hereby (A) do not contravene any provision of applicable law or the Certificate of Incorporation or By-Laws of the Company, (B) to our knowledge, will not result in the creation or imposition of any claim, lien or encumbrance upon any of the assets of the Company pursuant to the terms and provisions of, conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or give any party a right to terminate any of its obligations under, or result in the acceleration of any obligation under, any indenture, mortgage, deed of trust, voting trust agreement, loan agreement, bond, debenture, note agreement or other evidence of indebtedness, lease, contract or other agreement, document or instrument known to such counsel to which the Company is a party or by which the Company or any of its respective properties is bound or affected, or (C) to our knowledge, violate or conflict with (i) any judgment, ruling, decree or order or (ii) any statute, rule or regulation of any court or other governmental agency or body, applicable to the business or properties of the Company.
9.: To our knowledge, there is no document or contract of a character required to be described in the Registration Statement, the Pricing Prospectus or the Prospectus or to be filed as an exhibit to the Registration Statement that is not described or filed or incorporated by reference as required, and each description of such contracts and documents that is contained or incorporated by reference in the Registration Statement, the Statutory Prospectus and Prospectus fairly presents in all material respects the information required under the Act and the Rules and Regulations.
10.: The statements under the captions "Risk Factors—We have adopted certain anti-takeover measures that may make it more difficult for a third party to acquire us," "Item 1—Legal Proceedings," "Management—Company Stock Option Plans," "Management—Employment Contracts and Termination of Employment and Change of Control Arrangements," "Certain Relationships and Related Transactions" and "Description of Capital Stock" in the Pricing

Prospectus or the Prospectus or incorporated by reference therein, insofar as the statements constitute a summary of documents referred to therein or matters of law, are accurate summaries and fairly and correctly present, in all material respects, the information called for with respect to such documents and matters.

11.: The Company is not an "investment company" or an "affiliated person" of, or "promoter" or "principal underwriter" for, an "investment company," as such terms are defined in the Investment Company Act of 1940, as amended.
12.: The Shares have been duly authorized for listing on the Nasdaq Global Market, subject to notice of issuance.
13.: To our knowledge, no holder of securities of the Company has rights, which have not been waived, to require the Company to register with the Commission shares of Common Stock or other securities, as part of the offering contemplated hereby.
14.: The Registration Statement has become effective under the Act and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceeding for that purpose has been instituted or is pending, threatened or contemplated.
15.: The Registration Statement, the Pricing Prospectus and the Prospectus comply as to form in all material respects with the requirements of the Act and the Rules and Regulations (other than the financial statements incorporated by reference in the Registration Statement, the Pricing Prospectus or the Prospectus, as to which we do not express an opinion or belief).
16.: The documents incorporated by reference in the Pricing Prospectus and Prospectus (other than the financial statements as to which we do not express an opinion or belief), when they were filed with the Commission, complied as to form in all material respects with the requirements of the Exchange Act and the Exchange Act Rules and Regulations.

While we have participated in conferences with representatives of and accountants for the Company at which conferences the contents of the Registration Statement and Prospectus and related matters were discussed, we have not independently verified the accuracy or completeness of the information contained in the Registration Statement or the Prospectus. We have acted as counsel to the Company only in connection with the Company's public filings in the United States and do not represent the Company in their overseas subsidiaries or operations. Based solely upon our participation as described above in the preparation of the Registration Statement, the Prospectus and the documents incorporated therein by reference, no facts have come to our attention that lead us to believe that:

OPINION OF BEIJING OCEAN LAW FIRM

December 19, 2006

Xxxxxxx & Company, LLC
000 Xxxx Xxxxxx
Xxx Xxxx, XX 00000

Ladies and Gentlemen:

This opinion is furnished to you pursuant to Section 6(g) of the Underwriting Agreement dated December 14, 2006 (the "Agreement") by and between XXX, Inc., a Delaware corporation (the "Company"), and Xxxxxxx & Company, LLC (the "Underwriter"). We have served as counsel for the Company only in connection with the formation and ongoing operations of its Subsidiaries (as such term is defined below). Capitalized terms used in this opinion, unless specifically defined in this opinion, have the meanings given them in the Agreement.

In connection with this opinion we have examined the following:

I.: All proceedings and documents made available to us by the Company or its Subsidiaries relating to the formation of (1) Beijing Tongmei Xtal Technology, (2) Beijing Ji Ya Semiconductor Material Co., Ltd., (3) Nanjing Xxx Xxx Gallium Co., Ltd. and (4) Beijing Xx Xx Manufacturing Co., Ltd. (collectively, the "Subsidiaries") under the laws of the People's Republic of China ("PRC");
II.: Registration Statement No. 333-135474, filed on June 29, 2006 with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Securities Act"), the Pricing Prospectus and the Prospectus;
III.: The Agreement; and
IV.: Such instruments, corporate records, certificates and other documents as we have considered necessary or appropriate for the purposes of this opinion.

We are admitted to practice law only in the PRC, and we express no opinion concerning any law other than the law of the PRC.

As to factual matters, we have relied solely upon certificates of public officials and of officers of the Company and its Subsidiaries, oral and written representations made to us by officers of the Company and its Subsidiaries, an inquiry of attorneys within our firm who have performed services for the Company and its Subsidiaries and an examination of documents as set forth above; however, nothing has come to our attention which would lead us to believe that such certificates or representations are inaccurate.

Where we render an opinion "to our knowledge" or concerning an item "known to us" or our opinion otherwise refers to our knowledge, it is intended to indicate that during the course of our representation of the Company or its Subsidiaries, no information that would give us current actual knowledge of the inaccuracy of such statement has come to the attention of those attorneys in this firm who have rendered or are rendering substantive legal services to the Company or its Subsidiaries in the transactions contemplated by the Agreement. However, except as otherwise expressly indicated, we have not undertaken any independent investigation to determine the accuracy of such statement and

any limited inquiry undertaken by us during the preparation of this opinion letter should not be regarded as such an investigation; no inference as to our knowledge of any matters bearing on the accuracy of any such statement should be drawn from the fact of our representation of the Company or its Subsidiaries.

With respect to our opinion in Paragraph 1 that each of the Subsidiaries is qualified to do business and is in good standing in all jurisdictions where employing individuals or the ownership or leasing of property requires such qualification, we have relied solely upon written representations made to us by officers of the Company or its Subsidiaries as to the jurisdictions in which the Company or its Subsidiaries has employees or owns or leases property and certificates of public officials as to the Company's or its Subsidiaries' qualification and good standing.

With respect to our opinion in Paragraph 2 that all issued and outstanding shares of the Subsidiaries are fully paid, we have relied solely upon representations concerning the receipt by the Company or its Subsidiaries of consideration for such shares made to us in certificates executed by officers of the Company or its Subsidiaries.

With respect to our opinion in Paragraph 3, we have relied solely on an inquiry of officers of the Company or its Subsidiaries concerning pending or threatened legal and governmental proceedings, oral and written representations made to us by officers of the Company or its Subsidiaries and an inquiry of attorneys within our firm who perform legal services for the Company or its Subsidiaries.

With respect to our opinion in Paragraph 4(A) regarding laws applicable to the Company or its Subsidiaries, we have not conducted any special investigation of statutes, laws, ordinances, rules or regulations and our opinion with respect thereto is limited to such PRC statutes, laws, rules and regulations as in our experience are of general application. We have based our opinion on our experience with such laws as are typically applicable to the transactions of the type contemplated by the Agreement.

With respect to our opinion in Paragraph 4(B), and without limiting the paragraph above concerning our knowledge, our opinion is based only to our knowledge without any review of the Company's agreements or contracts.

With respect to our opinion in Paragraph 4(C) concerning judgments, orders or decrees, we have relied solely on representations made to us by officers of the Company and its Subsidiaries that there are no judgments, orders or decrees applicable to the Company or its Subsidiaries and an inquiry of attorneys within our firm who perform legal services for the Company or its Subsidiaries.

We express no opinion with respect to compliance or noncompliance with the antifraud provisions of United States state or federal laws, rules and regulations concerning the issuance of securities.;

Subject to and in reliance upon the foregoing, it is our opinion as of the date hereof that:

1.: Each of the Subsidiaries is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation; has full corporate power and authority to conduct all the activities conducted by it, to own or lease all the assets owned or leased by it and to conduct its business as described in the Registration Statement and Prospectus; and is duly licensed or qualified to do business and is in good standing as a foreign corporation in all jurisdictions in which it has employees or owns or leases real property.
2.: All of the outstanding shares of capital stock of each Subsidiary (the "Subsidiary Shares") have been duly authorized and validly issued, are nonassessable and are owned by the

Company in the percentage amounts set forth in the notes to the Company's consolidated financial statements incorporated by reference into the Pricing Prospectus and the Prospectus. To our knowledge, (i) the Subsidiary Shares were fully paid, (ii) the Subsidiary Shares are free and clear of all claims, liens, charges and encumbrances and (iii) there are no securities outstanding that are convertible into or exercisable or exchangeable for capital stock of any Subsidiary.

3.: To our knowledge, there are no legal or governmental proceedings pending or threatened to which the Company or any Subsidiary is a party or to which any of their respective properties is subject that are required to be described in the Registration Statement, the Pricing Prospectus or the Prospectus but are not so described.
4.: The execution and delivery of this Agreement, the compliance by the Company with all of the terms hereof and the consummation of the transactions contemplated hereby (A) do not contravene any provision of the applicable formation or governmental regulatory documents under PRC law of any Subsidiary or, to our knowledge, any law, (B) to our knowledge, will not result in the creation or imposition of any claim, lien, charge or encumbrance upon any of the assets of the Company or any Subsidiary pursuant to the terms and provisions of, conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or give any party a right to terminate any of its obligations under, or result in the acceleration of any obligation under, any indenture, mortgage, deed of trust, voting trust agreement, loan agreement, bond, debenture, note agreement or other evidence of indebtedness, lease, contract or other agreement, document or instrument known to us to which any such Subsidiary is a party or by which any such Subsidiary or any of its properties is bound or affected, or (C) to our knowledge, violate or conflict with (i) any judgment, ruling, decree or order or (ii) any statute, rule or regulation of any court or other governmental agency or body, applicable to the business or properties of the Company or any Subsidiary.

As stated above, we have acted as counsel to the Company and its Subsidiaries only in connection with the formation and ongoing operations of each Subsidiary. Based solely upon this representation, no facts have come to our attention that lead us to believe that:

(i) the Registration Statement (except as to the financial statements and schedules and other financial data contained or incorporated by reference therein, as to which we do not express any opinion or belief) as of its effective date, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading;

(iii) the Prospectus (except as to the financial statements and schedules and other financial data contained or incorporated by reference therein, as to which we do not express any opinion or belief) as of its date, the Closing Date or, if applicable, the Option Closing Date, included or includes any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

This opinion is solely for your benefit and is not to be made available to or relied upon by any other person without our express prior written consent.

Very Truly Yours,

Beijing Ocean Law Group
