Item 3.

Source and Amount of Funds or Other Consideration.

This Amendment amends the Schedule 13D filed by HealthpointCapital Partners, L.P., HGP, LLC, HealthpointCapital Partners II, L.P., HPCII Co-Invest Vehicle II, L.P., HGP II, LLC, Mortimer Berkowitz III and John H. Foster on April 12, 2010, which reported the transaction described in the following paragraph.

On March 26, 2010, Alphatec completed the acquisition of all of the outstanding stock of Scient’x S.A. (the “Acquisition”). As of February 1, 2010, HealthpointCapital Partners, L.P., HealthpointCapital Partners II, L.P., HCPII Co-Invest Vehicle II, L.P. and certain of their affiliates indirectly held approximately 94.8% of the shares of Scient’x S.A. The Acquisition was structured as an all stock transaction such that 100% of outstanding Scient’x stock was exchanged pursuant to a fixed ratio for 24,000,000 shares of the common stock of Alphatec. The consideration paid for 100% of the outstanding Scient’x stock was 23,730,644 shares of Alphatec’s common stock, which reflected a reduction in the 24,000,000 shares calculated at the closing in exchange for Alphatec’s payment of certain fees and expenses incurred by HealthpointCapital LLC (the parent company of HealthpointCapital Partners, L.P., HealthpointCapital Partners II, L.P. and HCPII Co-Invest Vehicle II, L.P. and referred to as “HealthpointCapital”) in connection with the Acquisition. HealthpointCapital Partners, L.P. received 6,732,534 shares of Alphatec’s common stock, HealthpointCapital Partners II, L.P. received 14,423,558 shares of Alphatec’s common stock and HCPII Co-Invest Vehicle II, L.P. received 1,344,179 shares of Alphatec’s common stock in consideration of their shares in Scient’x. Mortimer Berkowitz III and John H. Foster are also directors of either Scient’x or an affiliate of Scient’x. They did not receive any shares of Alphatec directly as a result of the Acquisition.

On April 21, 2010, Alphatec and HealthpointCapital Partners, L.P. completed an underwritten public offering of an aggregate of 18,400,000 shares of Alphatec common stock at a public offering price of $5.00 per share, less underwriting commissions and discounts, including 2,400,000 shares sold upon exercise in full of the underwriters’ over-allotment option. The shares were sold pursuant to an underwriting agreement by and among Alphatec, HealthpointCapital Partners, L.P. and Jefferies & Company, Inc. as representative of the underwriters set forth on Schedule A attached thereto, dated April 15, 2010, a copy of which has been filed as an exhibit to Alphatec’s Current Report on Form 8-K filed with the SEC on April 16, 2010. Of the shares of common stock sold in the offering, 9,200,000 shares were sold by Alphatec and 9,200,000 shares were sold by HealthpointCapital Partners, L.P. The purchase price per share paid by the underwriters to HealthpointCapital Partners, L.P. and Alphatec was $4.75. The net proceeds to HealthpointCapital Partners, L.P. were approximately $43.7 million after deducting underwriting discounts and commissions and estimated expenses. Alphatec did not receive any proceeds from the sale of shares of common stock by HealthpointCapital Partners, L.P, and HealthpointCapital Partners, L.P. did not receive any proceeds from the sale of shares of common stock by Alphatec.

The offering was made pursuant to a prospectus supplement dated April 16, 2010 and an accompanying prospectus dated April 9, 2010, pursuant to Alphatec’s existing effective shelf registration statement on Form S-3 (File No. 333-164891), which was initially filed with the SEC on February 12, 2010 and declared effective by the SEC on April 9, 2010.

Corporate Governance Agreement

In connection with the Acquisition, HealthpointCapital Partners, L.P. and HealthpointCapital Partners II, L.P.

However, the HealthpointCapital Shareholders may make a proposal to an independent committee of Alphatec’s board of directors with respect to certain of these transactions, so long as any such proposal is not publicly disclosed. The HealthpointCapital Shareholders have further agreed that if they become aware that they beneficially own more than a permitted number of Alphatec’s shares set forth in the agreement, then they shall promptly take all action necessary to reduce the number of beneficially owned shares in the aggregate to a permitted number of shares.

The HealthpointCapital Shareholders have also agreed that they will not transfer or permit any of their affiliates or associates to transfer any of their shares, except for transfers where no transferee would beneficially own more than the number of shares beneficially owned by the HealthpointCapital Shareholders as of the date of the agreement, transfers to its controlled affiliates, provided that such affiliate becomes a signatory to the agreement, transfers pursuant to a tender or exchange offer, merger or other business combination approved by the board of directors, transfers approved by an independent committee of Alphatec’s board of directors, or transfers to their limited or general partners, if, as a result, no transferee would beneficially own more than the number of shares held by the HealthpointCapital Shareholders as of the date of the corporate governance agreement.

Registration Rights Agreement

In connection with the closing of the Acquisition, Alphatec entered into a registration rights agreement with the HealthpointCapital Shareholders and the other Scient’x shareholders (referred to collectively as the “Registration Rights Holders”), pursuant to which the Registration Rights Holders have registration rights with respect to the shares issued in the Acquisition and any other of Alphatec’s shares held by such stockholders that constitute “restricted securities” under Rule 144 of the Securities Act (referred to as the “Registrable Shares”).

Pursuant to the registration rights agreement, a copy of which has been filed as an exhibit to Alphatec’s Current Report on Form 8-K filed with the SEC on March 31, 2010, the Registration Rights Holders have demand and piggy-back registration rights with respect to the Registrable Shares. At any time after June 24, 2010, the HealthpointCapital Shareholders may demand that Alphatec register all or a portion of the Registrable Shares for sale under the Securities Act, so long as the market value of such securities on the date of such request is at least $10 million or represent 3% of the total outstanding shares of Alphatec’s common stock. Alphatec will effect the registration as requested, unless disinterested members of Alphatec’s board of directors determine that such registration would materially interfere with any pending or contemplated acquisition, divestiture, financing, registered primary offering or other transaction, or would be materially detrimental to Alphatec and its stockholders, in which case Alphatec will have the right to defer such registration for a period of up to 60 days.

In addition, if at any time Alphatec registers any shares of its capital stock, other than in connection with (i) a registration pursuant to an exercise of demand rights described above, (ii) a registration relating solely to a business combination or merger involving Alphatec, (iii) a registration relating solely to Alphatec’s employee benefit plans, (iv) a registration relating to Alphatec’s reorganization or other transaction under Rule 145 of the Securities Act, or (v) any registration on any form that does not include substantially the same information as would be required to be included in a registration covering the sale of Registrable Securities, the Registration Rights Holders are entitled to notice of the registration and to include all or a portion of their Registrable Shares in the registration.

A holder’s right to demand or include Registrable Shares in a registration is subject to the right of the underwriters to limit the number of shares included in the offering.

Subject to certain exceptions and provided Alphatec’s officers and directors enter into similar agreements, in connection with a piggy-back registration, the Registration Rights Holders have agreed that they will not effect any public sale or distribution of Alphatec’s common stock, enter into a transaction which would have the same effect, or enter into any swap, hedge, or other arrangement that transfers, in whole or in part, any economic consequences of ownership of such securities, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, during the 10 days prior to and the 90 days after the effective time of any underwritten piggy-back registration in which any of such Registration Rights Holder’s Registrable Shares are included.

The registration rights agreement contains customary provisions allocating rights and responsibilities and obligating Alphatec and the Registration Rights Holders to indemnify each other against certain liabilities arising from any registration of securities.

The Registration Rights Holders have waived their right to include their Registrable Shares in the Registration Statement on Form S-3 filed by Alphatec with the SEC on February 10, 2010, as amended on April 2, 2010.
