Summary of ADVANCED CELL TECHNOLOGY, INC.

Item 1.01 Entry into a Material Definitive Agreement.

On September 19, 2012, Advanced Cell Technology, Inc., a Delaware corporation
(the "Company"), entered into a purchase agreement (the "Purchase Agreement")
with Lincoln Park Capital Fund, LLC, an Illinois limited liability company ("LPC"), pursuant to which the Company has the right to sell to LPC up to $35,000,000 in shares of its common stock, $.01 par value per share ("Common Stock"), subject to certain limitations set forth in the Purchase Agreement.

Upon signing the Purchase Agreement, LPC purchased 10,000,000 shares of Common Stock from the Company for $800,000 as an initial purchase under the agreement (the "Initial Purchase Shares").

On September 19, 2012, the Company and LPC also entered into a registration rights agreement (the "Registration Rights Agreement"), pursuant to which the Company is required to file a registration statement (the "Registration Statement") with the Securities and Exchange Commission (the "SEC") to register the resale of the shares of Common Stock issued and issuable to LPC pursuant to the Purchase Agreement.

Upon the satisfaction of the conditions set forth in the Purchase Agreement, including the Registration Statement being declared effective by the SEC, the Company has the right over a 36-month period to sell up to an additional $34.2 million worth of shares of our Common Stock to LPC, upon the terms set forth in the Purchase Agreement. Pursuant to the Purchase Agreement, the purchase price of such Common Stock will be based on the prevailing market price of the Company's Common Stock immediately preceding the time of sales, with the Company controlling the timing and amount of any future sales, if any, of Common Stock to LPC. There are no upper limits to the price LPC may pay to purchase our Common Stock. LPC shall not have the right or the obligation to purchase any shares of Common Stock on any business day that the closing price of our Common Stock is below a floor price as provided in the Purchase Agreement.

The Purchase Agreement contains customary representations, warranties, covenants, closing conditions and indemnification and termination provisions by, among and for the benefit of the parties. LPC has covenanted not to cause or engage in any manner whatsoever, any direct or indirect short selling or hedging of our Common Stock. The Purchase Agreement may be terminated by us at any time at our discretion without any cost to us. The proceeds received by the Company under the Purchase Agreement are expected to be used to fund the Company's clinical activities, including its three ongoing Phase I/II clinical trials for forms of macular degeneration, for development of its other clinical activities, and for general corporate purposes.

In consideration for entering into the Purchase Agreement, we issued to LPC 8,750,000 shares of our Common Stock as a commitment fee (the "Commitment Shares"). The Initial Purchase Shares and the Commitment Shares have been issued in reliance on an exemption from registration under the Securities Act of 1933, as amended (the "Securities Act"), pursuant to Section 4(2) thereof and Regulation D promulgated thereunder, and will be registered for resale on the registration statement that we must file pursuant to the Purchase Agreement and the Registration Rights Agreement.

This Current Report on Form 8-K shall not constitute an offer to sell or a solicitation of an offer to buy any shares of Common Stock, nor shall there be any sale of shares of Common Stock in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or other jurisdiction.

The foregoing description of the Purchase Agreement and the Registration Rights Agreement are qualified in their entirety by reference to the full text of the Purchase Agreement and the Registration Rights Agreement, a copy of each of which is attached hereto as Exhibit 10.1 and 10.2, respectively, and each of which is incorporated herein in its entirety by reference.
