The Company shall deliver, at least ten (10) Business Days prior to the closing of a Subsequent Placement, to SDL, a written notice (the “Pre-Notice”) of any proposed Subsequent Placement (the “Offer”) describing the securities being offered (the “Offered Securities”), which Pre-Notice shall inquire whether SDL or its Affiliates desire to review the details of the Offer. Upon request of SDL or an affiliate of SDL for the details of such Offer provided by SDL or such Affiliate of SDL to the Company within three (3) Business Days of SDL’s receipt of the applicable Pre-Notice, the Company will promptly, but in no event later than one (1) Business Day after such request, deliver a subsequent notice (such additional notice, a “Subsequent Financing Notice”) to SDL or such Affiliate of SDL, which Subsequent Financing Notice shall (a) identify and describe the Offered Securities; (b) describe in reasonable detail, if known, the price (or anticipated price range) and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities proposed to be issued, sold or exchanged; and (c) offer to issue and sell to SDL and its Affiliates a portion of such Offered Securities equal to SDL’s Pro Rata Portion. SDL acknowledges that the Subsequent Financing Notice may not contain the price or other terms upon which the Offered Securities will ultimately be issued; provided that the Company shall deliver to SDL written notice of the price and other definitive terms of the Offered Securities contemporaneously with all other purchasers of the Offered Securities (the “Final Financing Notice”).

5.1.2 Acceptance. To accept an Offer, in whole or in part, SDL or an Affiliate of SDL must deliver a written notice to the Company setting forth the portion of SDL’s Pro Rata Portion of such Offered Securities that SDL or such Affiliate of SDL elect to purchase by the date and time that is the later of (a) 5:30 p.m. Eastern Time on the fifth (5th) Business Day after it receives the Subsequent Financing Notice or (b) twenty-four (24) hours after it receives the Final Financing Notice.

5.1.3 Exclusions. The rights and restrictions contained in this Section 5.1 shall not apply to: (a) shares of Common Stock, options, warrants or other convertible securities issued to employees or officers or directors or outside consultants or contractors of the Company or any subsidiary pursuant to a plan, agreement or arrangement duly approved by the Board; (b) shares of capital stock issued by the Company upon the exercise or conversion of options or other stock awards outstanding immediately prior to the Initial Closing or issued after the Initial Closing in accordance with clause (a) of this Section 5.1.3; (c) shares of capital stock issued by the Company upon the exercise or conversion of warrants to purchase capital stock of the Company or other convertible securities (i) outstanding immediately prior to the Initial Closing or (ii) issued after the Initial Closing pursuant to an exemption from this Section 5.1 or otherwise in compliance with this Section 5.1; (d) securities issued in connection with any borrowings, direct or indirect, from a bank or other financial institution by the Company, provided that such issuance is pursuant to an agreement or arrangement duly approved by the Board; (e) securities issued in connection with the Company obtaining lease financing, whether issued to a lessor, guarantor or other person; (f) securities issued in connection with the acquisition of all or a substantial portion of the assets or the business of another entity by the Company; (g) securities issued in connection with a corporate partnering transaction, strategic alliance, technology transfer, license or similar transaction; or (h) any shares of Common Stock sold at a price equal to or greater than the Purchase Price (as adjusted for any stock splits, stock dividends, stock combinations, and similar events occurring after the date hereof) or any other capital stock or other securities of any type whatsoever convertible into or exchangeable for Common Stock at a price equal to or greater than the Purchase Price (as adjusted for any stock splits, stock dividends, stock combinations, and similar events occurring after the date hereof).

5.1.4 Separate Financing. Notwithstanding anything to the contrary set forth in this Section 5.1, this Section 5.1 shall not prohibit the Company from consummating a Subsequent Placement if the Company has been advised by an investment bank, underwriter, placement agent or other financial or legal advisor that compliance with the terms of Section 5.1.1 or Section 5.1.2 could reasonably be expected to jeopardize the ability of the Company to consummate such Subsequent Placement; provided, however, that, subject to the rules and regulations of the SEC, the NASDAQ Stock Market LLC or any other applicable exchange on which the Company’s Common Stock is listed or quoted, immediately following the consummation of such Subsequent Placement, the Company shall use commercially reasonably efforts to offer to SDL and its Affiliates the right to purchase up to its Pro Rata Portion of the Offered Securities in such Subsequent Placement on the same terms, conditions and price provided for in the Subsequent Placement under the same conditions and within the timeframe set forth in Sections 5.1.1 and 5.1.2.

5.1.5 Termination. The Company’s obligations and the rights of SDL and its Affiliates under this Section 5.1 shall terminate on the earliest of (a) such time as the SDL Ownership Condition ceases to be satisfied; (b) the five (5) year anniversary of the Initial Closing; (c) the date that the Company’s Common Stock is listed on a national securities exchange, including the New York Stock Exchange, the NASDAQ Global Market or the NYSE Alternext (formerly the American Stock Exchange); or (d) the date of the closing of a sale, lease, or other disposition of all or substantially all of the Company’s assets or the Company’s merger into or consolidation with any other corporation or other entity, or any other corporate reorganization, in which the holders of the Company’s outstanding voting stock immediately prior to such transaction own, immediately after such transaction, securities representing less than fifty percent (50%) of the voting power of the corporation or other entity surviving such transaction, provided that this Section 5.1.5 shall not apply to a merger effected exclusively for the purpose of changing the domicile of the Company or a sale of shares by the Company for primarily equity financing purpose.

5.2 Board of Directors Designee. At the request of SDLV, the Company shall within thirty (30) days of the request take all necessary acts to have one designee (the “Board Member Designee”) of SDLV nominated for election to the Board, subject to the approval by the remaining Board, which shall not be unreasonably withheld or delayed, and in all cases subject to compliance with relevant rules and regulations of the SEC and any applicable exchange on which the Company’s Common Stock is listed or quoted. The Board Member Designee must have relevant industry or academic experience and satisfy the independence requirements of the NASDAQ Global Market or any then applicable exchange on which the Company’s Common Stock is listed or quoted. Subject to the terms and conditions of this Section 5.2, at SDLV’s request, the Company shall use its commercially reasonable efforts, including preparation of proxy materials and solicitation of the Company’s stockholders, to have the Board Member Designee elected whenever its board seat comes up for election or for reelection at any regularly scheduled meeting of the Company’s stockholders. The Company’s obligations under this Section 5.2 with respect to the Board Member Designee shall terminate in their entirety if at any time (i) the SDL Ownership Condition ceases to be satisfied or (ii) the Company’s obligations under this Section 5.2 become inconsistent with the rules, regulations and guidance of the applicable exchange on which the Company’s Common Stock may become listed or quoted, and in each such case, the Board Member Designee shall resign from the Board effective immediately. In the event that the Board Member Designee resigns in accordance with clause (ii) above, the Company acknowledges that SDLV shall remain entitled to designate a board member if it is otherwise in compliance with this Section 5.2 and such right is consistent with the rules, regulations and guidance of the applicable exchange on which the Company’s Common Stock may become listed or quoted.

5.3 Piggy-Back Registration Rights.

5.3.1 Notice of Piggyback Registration and Inclusion of Registrable Securities. Subject to the terms of this Agreement, in the event the Company decides to Register any of its capital stock (either for its own account or the account of any security holder or holders) on a form (other than a Registration on Form S-4 and Form S-8, as those forms are issued by the SEC or any substantially similar forms then in effect) that would be suitable for a Registration involving solely Registrable Securities, the Company will: (i) promptly give each Investor written notice thereof (which shall include a list of the jurisdictions in which the Company intends to attempt to qualify such securities under the applicable Blue Sky or other state securities laws) and (ii) include in such Registration (and any related qualification under Blue Sky laws or other compliance), and in any underwriting involved therein, all the Registrable Securities specified in a written request delivered to the Company by any Investor within fifteen (15) days after delivery of such written notice from the Company.

5.3.2 Underwriting in Piggyback Registration.

(a) Notice of Underwriting in Piggyback Registration. If the Registration of which the Company gives notice pursuant to Section 5.3.1 is for a Registered public offering involving an underwriting, the Company shall so advise the Investors as a part of the written notice given pursuant to Section 5.3.1. In such event the right of any Investor to Registration shall be conditioned upon such underwriting and the inclusion of such Investor’s Registrable Securities in such underwriting to the extent provided in this Section 5.3. All Investors proposing to distribute their securities through such underwriting shall (together with the Company and the other holders distributing their securities through such underwriting) enter into an underwriting agreement with the underwriter selected by the Company (the “Underwriter’s Representative”) for such offering. The Investors shall have no right to participate in the selection of the underwriters for an offering pursuant to this Section 5.3.

(b) Marketing Limitation in Piggyback Registration. In the event the Underwriter’s Representative advises the Investors seeking Registration of Registrable Securities pursuant to this Section 5.3 in writing that market factors (including, without limitation, the aggregate number of shares of Common Stock requested to be Registered, the general condition of the market, and the status of the persons proposing to sell securities pursuant to the Registration) require a limitation of the number of shares to be underwritten, the Underwriter’s Representative (subject to the allocation priority set forth in Section 5.3.2(c)) may:

i. in the case of the Company’s first Registered public offering after the date hereof, exclude some or all Registrable Securities from such Registration and underwriting; and

ii. in the case of any subsequent registered public offering, limit the number of shares of Registrable Securities to be included in such Registration and underwriting to not less than thirty percent (30%) of the securities included in such Registration (based on aggregate market values); provided that the only securities included in such Registration are those offered by the Company and/or the Investors.

(c) Allocation of Shares in Piggyback Registration. In the event that the Underwriter’s Representative limits the number of shares to be included in a Registration pursuant to Section 5.3.2(b), the number of shares to be included in such Registration shall be allocated (subject to Section 5.3.2(b)) in the following manner: The number of shares, if any, that may be included in the Registration and underwriting by selling stockholders shall first be allocated among all the requesting Investors pro rata according to the respective amounts of Registrable Securities entitled to be included in such offering by such requesting Investors and then among all other holders of securities other than Registrable Securities requesting and legally entitled to include shares in such Registration, in proportion, as nearly as practicable, to the respective amounts of securities (including Registrable Securities) which such Investors and such other holders would otherwise be entitled to include in such Registration. No Registrable Securities or other securities excluded from the underwriting by reason of this Section 5.3.2(c) shall be included in the Registration Statement. To facilitate the allocation of shares in accordance with the above provisions, the Company or the Underwriter’s Representative may round the number of shares allocated to any Investor to the nearest one hundred (100) shares.

(d) Withdrawal in Piggyback Registration. If any Investor disapproves of the terms of any such underwriting, he, she or it may elect to withdraw therefrom by written notice to the Company and the underwriter delivered at least seven (7) Business Days prior to the effective date of the Registration Statement. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such Registration.

5.3.3 Blue Sky in Piggyback Registration. In the event of any Registration of Registrable Securities pursuant to this Section 5.3, the Company will exercise its best efforts to Register and qualify the securities covered by the Registration Statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably appropriate for the distribution of such securities; provided, however, that (i) the Company shall not be required to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, and (ii) notwithstanding anything in this Agreement to the contrary, in the event any jurisdiction in which the securities shall be qualified imposes a non-waivable requirement that expenses incurred in connection with the qualification of the securities be borne by selling stockholders, such expenses shall be payable pro rata by selling stockholders.

5.4 Registration Procedures. In the case of each registration, qualification or compliance effected by the Company pursuant to Section 5.3, the Company will:

5.4.1 Bear all Registration Expenses incurred in connection with Section 5.3. All Selling Expenses relating to securities held by stockholders and being sold in any Registration shall be borne by the respective holders of such securities Registered pro rata on the basis of the number of shares registered.

5.4.2 Keep each Investor whose Registrable Securities are included in any Registration pursuant to this Agreement advised as to the initiation and completion of such Registration. At its expense the Company will: (i) use its commercially reasonable efforts to keep such Registration effective for a period of one hundred twenty (120) days or until the Investor or Investors have completed the distribution described in the Registration Statement relating thereto, whichever first occurs; and (ii) furnish such number of prospectuses (including preliminary prospectuses) in conformity with the Securities Act and such other documents as a Investor from time to time may reasonably request. With respect to clause (i) of the preceding sentence, the Company may at any time upon written notice to the participating Investors delay the filing or effectiveness of any registration statement or suspend the use or effectiveness of any registration statement (and the Investors hereby agree not to offer or sell any Registrable Securities pursuant to such registration statement during such time) if the Company reasonably believes that the Company may, in the absence of such delay or suspension hereunder, be required under state or federal securities laws to disclose any corporate development the disclosure of which could reasonably be expected to have an adverse effect upon the Company, its stockholders, a potentially significant transaction or event involving the Company, or any negotiations, discussions, or proposals directly relating thereto.

5.4.3 Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statements as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for the periods specified in Section 5.4.2 above;

5.4.4 Promptly notify each Investor of Registrable Securities covered by the registration statement at any time when the Company becomes aware of the happening of any event as a result of which the registration statement or the prospectus included in such registration statement or any supplement to the prospectus (as then in effect) contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements therein (in the case of the prospectus, in light of the circumstances under which they were made) not misleading or, if for any other reason it shall be necessary during such time period to amend or supplement the registration statement or the prospectus in order to comply with the Securities Act, whereupon, in either case, each Investor shall immediately cease to use such registration statement or prospectus for any purpose and, as promptly as practicable thereafter, the Company shall prepare and file with the SEC, and furnish without charge to the appropriate Investors and managing underwriters, if any, a supplement or amendment to such registration statement or prospectus which will correct such statement or omission or effect such compliance and such copies thereof as the Investors and any underwriters may reasonably request;

5.4.5 Use its commercially reasonable efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Investors, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions except as may be required by law; and

5.4.6 In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering. Each Investor participating in such underwriting shall also enter into and perform its obligations under such an agreement.

5.5 Information Furnished by Investor. It shall be a condition precedent of the Company’s obligations under Sections 5.3 and 5.4 of this Agreement that each Investor holding Registrable Securities to be included in any Registration furnish to the Company such information regarding such Investor and the distribution proposed by such Investor as the Company may reasonably request.

5.6 Termination of Registration Rights. The Registration rights set forth in Sections 5.3 and 5.4 shall terminate upon the earlier of (a) seven (7) years after the date hereof or (b) when such Investor is entitled to sell all of such Investor’s Registrable Securities without volume restriction pursuant to Rule 144.

SECTION VI
RIGHT OF FIRST REFUSAL ON CERTAIN SDL TRANSFERS.

6.1 Notices. If SDL or any of its Affiliates (collectively, a “Transferor”) proposes to sell, assign, hypothecate or otherwise transfer (a “Transfer”) any of the SDL Shares, other than pursuant to the provisions of Section 6.4 of this Agreement, the Transferor shall first give the Company the right to purchase such SDL Shares by delivering to it a written offer which shall state the price and other terms and conditions of the proposed Transfer. If the Transferor proposes to Transfer the SDL Shares for consideration other than solely cash and/or promissory notes, the offer to the Company shall, to the extent of such consideration, permit the Company to pay in lieu thereof, cash equal to the fair market value of such consideration, and the offer shall state the estimate of such fair market value as determined by the Board. The Transferor shall fix the period of the offer which shall be a minimum of five (5) Business Days or such longer period as is necessary to determine the fair market value of the consideration referred to in the preceding sentence.

6.2 Acceptance of Offer.

The Company may, in its sole discretion, assign the right of first refusal set forth in this Section VI to its Affiliates and other stockholders. Within thirty (30) days following the Acceptance Notice, the Company or its permitted assigns shall deliver to the Transferor payment in full for the Accepted Shares purchased by it against delivery by the Transferor to the Company of a certificate or certificates evidencing the Accepted Securities.

6.3 Failure to Exercise. To the extent an Acceptance Notice is not provided pursuant to Section 6.2, the Transferor may, for a period of thirty (30) days thereafter, transfer the unaccepted SDL Shares, or any of them, at or above the price, and upon the other terms and conditions specified in such offer, to any Person or Persons.

6.4 Exempt Transfers. Notwithstanding anything to the contrary contained in this Section VI:

6.4.1 Any Transferor which is a partnership or limited liability company may Transfer (without first offering any SDL Shares to the Company) all or any of its SDL Shares to any of its Affiliates or successor funds or to a partner or retired partner or member or retired member of such partnership or limited liability company, as the case may be, or to one or more direct or indirect partners, directors, officers, members or other equity holders of any such Affiliates, successor funds, partners or retired partners, members or retired members, or to the estate of any of the foregoing or transfer by will or intestate succession to the spouse or to the siblings, lineal descendants or ancestors of any of the foregoing or the spouse of any of the foregoing; provided such transferee agrees in writing with the Company, prior to and as a condition precedent to such Transfer, to be bound by all of the provisions of this Section VI;

6.4.2 Any Transferor which is a corporation may Transfer (without first offering any SDL Shares to the Company) all or any of its SDL Shares to any of its Affiliates; provided such Affiliate agrees in writing with the Company, prior to and as a condition precedent to such Transfer, to be bound by all of the provisions of this Section VI;

6.4.3. Any Transferor who is an individual may Transfer (without first offering any SDL Shares to the Company) all or any of his or her SDL Shares to his or her spouse or their spouse’s siblings, lineal descendants or ancestors, nieces or nephews or any person sharing his or her household (other than a tenant or employee), or any entity that is an Affiliate of such Transferor; provided such transferee agrees in writing with the Company, prior to and as a condition precedent to such Transfer, to be bound by all of the provisions of this Section VI;

6.4.4. Any Transferor that is a trust may Transfer (without first offering any SDL Shares to the Company) all or any of its SDL Shares to any settlor or beneficiary of the Transferor, to any settlor or beneficiary’s spouse or their spouse’s siblings, lineal descendants or ancestors, nieces or nephews or any person sharing his or her household (other than a tenant or employee), or any person that is an Affiliate of such Transferor; provided such transferee agrees in writing with the Company, prior to and as a condition precedent to such Transfer, to be bound by all of the provisions of this Section VI;

6.4.5 Any Transferor may Transfer (without first offering any SDL Shares to the Company) all or any of its, his or her SDL Shares pursuant to an underwritten Registered public offering, including, pursuant to Section 5.3 above; and

6.4.6 Any Transferor may Transfer (without first offering any SDL Shares to the Company) all or any of its, his or her SDL Shares pursuant to a merger of the Company into or consolidation with any other corporation or other entity, or any other corporate reorganization, in which the holders of the Company’s outstanding voting stock immediately prior to such transaction own, immediately after such transaction, securities representing less than fifty percent (50%) of the voting power of the corporation or other entity surviving such transaction.

6.5 Termination. SDL’s obligations and the Company’s rights under this Section VI shall terminate on the earliest of: (a) the five (5) year anniversary of the Initial Closing; (b) the date that the Company’s Common Stock is listed on a national securities exchange, including the New York Stock Exchange, the NASDAQ National Market or the NYSE Alternext (formerly the American Stock Exchange); or (c) the date of the closing of a sale, lease, or other disposition of all or substantially all of the Company’s assets or the Company’s merger into or consolidation with any other corporation or other entity, or any other corporate reorganization, in which the holders of the Company’s outstanding voting stock immediately prior to such transaction own, immediately after such transaction, securities representing less than fifty percent (50%) of the voting power of the corporation or other entity surviving such transaction, provided that this Section 6.5 shall not apply to a merger effected exclusively for the purpose of changing the domicile of the Company or a sale of shares by the Company for primarily equity financing purpose.
