EXPLANATORY NOTE

 

Fluidigm Corporation has prepared this Amendment No. 5 to the Registration Statement on Form S-1 (File No. 333-150227) for the purpose of refiling Exhibits 4.2, 4.4, 10.6, 10.9 and 10.15 to the Registration Statement with the Securities and Exchange Commission. This Amendment No. 5 does not modify any provision of the prospectus that forms a part of the Registration Statement, and accordingly such prospectus has not been included herein.

PART II

 

INFORMATION NOT REQUIRED IN PROSPECTUS

 

 

The following table sets forth all expenses to be paid by the registrant, other than estimated underwriting discounts and commissions, in connection with this offering. All amounts shown are estimates except for the SEC registration fee, the NASD filing fee and the NASDAQ Global Market listing fee.

 

 

 

 

 

Section 145 of the Delaware General Corporation Law authorizes a corporation’s board of directors to grant, and authorizes a court to award, indemnity to officers, directors and other corporate agents.

 

As permitted by Section 102(b)(7) of the Delaware General Corporation Law, the registrant’s certificate of incorporation includes provisions that eliminate the personal liability of its directors and officers for monetary damages for breach of their fiduciary duty as directors and officers.

 

In addition, as permitted by Section 145 of the Delaware General Corporation Law, the bylaws of the registrant provide that:

 

 

 

The registrant’s policy is to enter into separate indemnification agreements with each of its directors and officers that provide the maximum indemnity allowed to directors and executive officers by Section 145 of the Delaware General Corporation Law and also provides for certain additional procedural protections. The registrant also maintains directors and officers insurance to insure such persons against certain liabilities.

 

These indemnification provisions and the indemnification agreements entered into between the registrant and its officers and directors may be sufficiently broad to permit indemnification of the registrant’s officers and directors for liabilities (including reimbursement of expenses incurred) arising under the Securities Act.

 

The underwriting agreement filed as Exhibit 1.1 to this registration statement provides for indemnification by the underwriters of the registrant and its officers and directors for certain liabilities arising under the Securities Act and otherwise.

 

 

In the three years prior to the filing of this registration statement, the registrant has issued the following unregistered securities:

None of the foregoing transactions involved any underwriters, underwriting discounts or commissions, or any public offering, and the registrant believes that each transaction was exempt from the registration requirements of the Securities Act in reliance on the following exemptions:

 

 

 

(a) Exhibits.  The following exhibits are included herein or incorporated herein by reference:

 

 

 

 

(b) Financial Statement Schedules.

 

All schedules have been omitted because the information required to be presented in them is not applicable or is shown in the consolidated financial statements or related notes.

 

Item 17.  Undertakings.

 

The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

 

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

 

The undersigned registrant hereby undertakes that:

 

(1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

 

(2) For the purpose of determining any liability under the Securities Act of 1933, each post effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to

the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

 

(3) For the purpose of determining liability under the Securities Act of 1933 to any purchaser, if the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

 

(4) For the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser to the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchasers and will be considered to offer or sell such securities to such purchaser:

 

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

 

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

 

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

 

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

Any waiver, permit, consent or approval of any kind or character on the part of any holder of any breach or default under this Agreement, or any waiver on the part of any holder of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing or as provided in this Agreement.

Pursuant to Rule 3-310 of the Rules of Professional Conduct promulgated by the State Bar of California, an attorney must avoid representations in which the attorney has or had a relationship with another party interested in the representation without the informed written consent of all parties affected. By executing this Agreement, each of the Purchasers and the Company hereby waives any actual or potential conflict of interest that may arise in this financing as a result of WSGR’s representation of such persons or entities, WSGR’s possession of such confidential information and the participation by WSGR’s affiliate in the financing. Each of the Purchasers and the Company represents that it has had the opportunity to consult with independent counsel concerning the giving of this waiver.

          6.12 Severability. In the event that any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Agreement shall continue in full force and effect without said provision; provided that no such severability shall be effective if it materially changes the economic benefit of this Agreement to any party.

          6.13 Counterparts; Facsimile. This Agreement may be executed in any number of counterparts, each of which may be executed by less than all Purchasers, each of which shall be enforceable against the parties actually executing such counterparts, and all of which together shall constitute one instrument.

          6.15 Exculpation Among Purchasers. Each Purchaser acknowledges that it is not relying upon any person, firm or corporation (including without limitation any other Purchaser), other than the Company and its officers and directors (acting in their capacity as representatives of the Company), in deciding to invest and in making its investment in the Company. Each Purchaser agrees that no other Purchaser nor the respective controlling persons, officers, directors, partners, agents or employees of any other Purchaser shall be liable to such Purchaser for any losses incurred by such Purchaser in connection with its investment in the Company.

          6.16 Like Treatment of Holders. The Company shall not directly or indirectly pay or cause to be paid any consideration, whether by way of interest, fee, payment for the redemption or exchange of Preferred Stock, or otherwise to any holder of Preferred Stock for or as inducement to, any consent, waiver or amendment of any term or provision of the Preferred Stock, this Agreement or the Investor Rights Agreement unless equivalent consideration is offered on equivalent terms and conditions to all Purchasers of Preferred Stock under this Agreement bound by such consent, waiver or amendment.

          6.17 Jury Trial. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING (WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATED TO THIS AGREEMENT.

FLUIDIGM CORPORATION

AMENDMENT NO. 1 TO
SERIES E PREFERRED STOCK PURCHASE AGREEMENT

     This Amendment No. 1 (the “Amendment”) to that certain Series E Preferred Stock Purchase Agreement, dated as of June 13, 2006 (the “Purchase Agreement”), is made and entered into effective as of December 22, 2006 (the “Effective Date”) by and among Fluidigm Corporation, a California corporation (the “Company”), and the Purchasers named therein. Capitalized terms used in this Amendment that are not otherwise defined herein shall have the respective meanings assigned to them in the Purchase Agreement.

RECITALS

     WHEREAS, the Company previously sold and issued an aggregate of 1,250,000 shares of Series E Preferred Stock of the Company (the “Series E Preferred”) pursuant to the terms of the Purchase Agreement at the Initial Closing held on June 13, 2006;

     WHEREAS, the Company and the Purchaser now desire to amend the terms of the Purchase Agreement to provide that the Company may sell and issue additional shares of Series E Preferred pursuant to the Purchase Agreement, at one or more additional Subsequent Closings, provided that any such additional Subsequent Closings shall take place no later than March 31, 2007.

     WHEREAS, pursuant to Section 6.5 of the Purchase Agreement, the terms of the Purchase Agreement may be amended upon the written consent of the Company and the holder or holders of greater than fifty percent (50%) of the outstanding Shares or the Conversion Shares; and

     WHEREAS, the Purchaser who has signed below holds greater than fifty percent (50%) of the outstanding Shares purchased under the Purchase Agreement as of the Effective Date and consents to the changes as set forth in this Amendment.

     NOW, THEREFORE, in consideration of the foregoing, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto mutually agree as follows:

AGREEMENT

     1. Amendment to Section 1.1. Section 1.1 (Authorization of the Shares) of the Purchase Agreement is hereby amended and restated in its entirety as follows:

     “1.1 Authorization of the Shares. The Company will on or before the Closing (as defined below) authorize the sale and issuance pursuant to this Agreement of up to 6,318,333 shares (the “Shares”) of its

Series E Preferred Stock (the “Series E Preferred”), having the rights, preferences and privileges as set forth in the Amended and Restated Articles of Incorporation attached hereto as EXHIBIT B (the “Restated Articles”).”

     2. Amendment to Section 1.2. Section 1.2 (Purchase and Sale of the Shares) of the Purchase Agreement is hereby amended and restated in its entirety as follows:

     “1.2 Purchase and Sale of the Shares. Subject to the terms and conditions hereof and in reliance upon the representations, warranties and agreements contained herein, the Company will issue and sell to each Purchaser, severally and not jointly, and each Purchaser will purchase from the Company, severally and not jointly, at the Closing, the number of Shares set forth opposite the Purchaser’s name on the Schedule of Purchasers, at a purchase price of Four Dollars ($4.00) per Share. The Company shall be entitled to sell any unpurchased Shares to any Purchaser or to a person who is not a Purchaser and to amend the Schedule of Purchasers to include the information relating to such sales, and such purchasers shall be considered “Purchasers” and parties to this Agreement; provided that (i) such sales are made pursuant to this Agreement or an agreement identical to this one except for the Closing Date and exhibits, and (ii) such sales are completed on or prior to March 31, 2007. The Company’s agreement with each Purchaser is a separate agreement, and the sale of the Shares to each Purchaser is a separate sale.”

     3. Governing Law. This Amendment shall be governed in all respects by the laws of the State of California, without regard to any provisions thereof relating to conflicts of laws among different jurisdictions.

     4. Purchase Agreement. Wherever necessary, all other terms of the Purchase Agreement are hereby amended to be consistent with the terms of this Amendment. Except as specifically set forth herein, the Purchase Agreement shall remain in full force and effect.

     5. Counterparts; Facsimile. This Amendment may be executed in any number of counterparts, each of which shall be an original, and all of which together shall constitute one instrument. Executed signatures transmitted via facsimile will be accepted and considered duly executed.

     6. Effect of Execution of Amendment by Certain Purchaser. This Amendment, when executed and delivered by the Company and a Purchaser purchasing shares of Series E Preferred at a Subsequent Closing held on or after the date hereof, shall also constitute and shall be deemed a counterpart signature page to the Purchase Agreement. Consequently, each undersigned Purchaser purchasing shares of Series E Preferred at a Subsequent Closing held on or after the date hereof acknowledges and agrees that he, she or it is bound by the terms and

conditions contained in the Purchase Agreement, as amended by this Amendment, with respect to the purchase of such shares.

     WHEREAS, Fluidigm California previously sold and issued an aggregate of 1,250,000 shares of Series E Preferred Stock (the “Series E Preferred”) pursuant to the terms of the Purchase Agreement at the Initial Closing held on June 13, 2006 and an additional 6,015,499 shares of Series E Preferred at Subsequent Closings held on December 22, 2006 and March 30, 2007;

     WHEREAS, on July 18, 2007, Fluidigm California was merged with and into the Company, with the Company being the surviving corporation such that the Company succeeded to all of Fluidigm California’s rights and obligations under the Purchase Agreement and all outstanding shares of Series E Preferred of Fluidigm California were exchanged on a one for one basis for shares of Series E Preferred of the Company;

     WHEREAS, the Company and the Purchasers now desire to amend the terms of the Purchase Agreement to provide that the Company may sell and issue up to 7,375,000 additional shares of Series E Preferred (the “Additional Shares”) pursuant to the Purchase Agreement, at one or more additional Subsequent Closings, provided that any such additional Subsequent Closings shall take place no later than December 31, 2007.

The Company shall be entitled to sell any unpurchased Shares to any Purchaser or to a person who is not a Purchaser and to amend the Schedule of Purchasers to include the information relating to such sales, and such purchasers shall be considered “Purchasers” and parties to this Agreement; provided that (i) such sales are made pursuant to this Agreement or an agreement identical to this one except for the Closing Date and exhibits, and (ii) such sales are completed on or prior to December 31, 2007. The Company’s agreement with each Purchaser is a separate agreement, and the sale of the Shares to each Purchaser is a separate sale.”

     10. Governing Law. This Amendment shall be governed in all respects by the laws of the State of California, without regard to any provisions thereof relating to conflicts of laws among different jurisdictions.

     11. Purchase Agreement. Wherever necessary, all other terms of the Purchase Agreement are hereby amended to be consistent with the terms of this Amendment. Except as specifically set forth herein, the Purchase Agreement shall remain in full force and effect.

     12. Counterparts; Facsimile. This Amendment may be executed in any number of counterparts, each of which shall be an original, and all of which together shall constitute one instrument. Executed signatures transmitted via facsimile will be accepted and considered duly executed.

     13. Effect of Execution of Amendment by Certain Purchasers. This Amendment, when executed and delivered by the Company and a Purchaser purchasing shares of Series E Preferred at a Subsequent Closing held on or after the date hereof, shall also constitute and shall be deemed a counterpart signature page to the Purchase Agreement. Consequently, each undersigned Purchaser purchasing shares of Series E Preferred at a Subsequent Closing held on or after the date hereof acknowledges and agrees that he, she or it is bound by the terms and conditions contained in the Purchase Agreement, as amended by this Amendment, with respect to the purchase of such shares.
