AGREEMENT

Exhibit 10.9

AGREEMENT

This Agreement (“Agreement”) is made as of September 15, 2005, by and among the following parties (collectively, the “Parties”):

PARTIES

A.                                   A.C.T. Group, Inc., a Delaware corporation with a principal place of business in Worcester, Massachusetts (“Group”);

B.                                     Advanced Cell Technology, Inc., a Nevada corporation, with a principal place of business in Los Angeles, California (“ACTC”).

C.                                     Advanced Cell, Inc., a Delaware corporation and a wholly-owned subsidiary of ACTC, with a principal place of business in Worcester, Massachusetts (“ACT”); and

RECITALS

1.                                       Group issued a series of sixteen (16) separate promissory notes over the period beginning December 23, 1999 and ending April 30, 2002, totaling $3,975,000 in aggregate principal amount (the “Bridge Notes”) to certain noteholders (the “Noteholders”), including Gary Aronson (“Aronson”) and John Gorton (“Gorton”).  The transactions resulting in the issuance of certain of the Bridge Notes involved the issuance of warrants to purchase shares of Group.   Group is currently in default on all Bridge Notes.  Group currently has no cash to extinguish or reduce the amounts due under (i) the Bridge Notes, or (ii) any other indebtedness of Group, including the indebtedness owed to Aronson and Gorton.

2.                                       Aronson and Gorton have initiated lawsuits against Group, and certain other parties, seeking to collect amounts due under their Bridge Notes and seeking other

remedies related thereto, all as more specifically set forth in the lawsuit listed below:

•                  Gary D. Aronson and John Gorton v. A.C.T. Group, Inc., Advanced Cell Technology, Inc, Michael D. West and Gunnar L. Engstrom, Worcester, Massachusetts Superior Court, No. 2004-CV-00523

The foregoing actions are hereinafter collectively referred to as the “Bridge Note Litigation” and the underlying claims and causes of action in such actions are referred to as the ”Aronson/Gorton Claims.”  Aronson and Gorton have received a judgment in their favor against Group in connection with the Bridge Note Litigation.

3.                                       The existence of the Bridge Note Litigation, the status of the Bridge Notes held by Aronson and Gorton and the uncertainty surrounding the judgment of the Bridge Note Litigation continue to have an adverse effect upon the stability of ACTC and its financing activities.

4.                                       Therefore, pursuant to the terms of that certain Settlement Agreement by and between Aronson, Gorton, ACT, ACTC and the other parties thereto (the “Aronson/Gorton Settlement Agreement”), ACTC has agreed to settle the Bridge Note Litigation by Aronson and Gorton assigning their respective Bridge Notes and the Aronson/Gorton Claims to ACTC in exchange for the issuance by ACTC of ACTC cash, notes and warrants (collectively, the “Settlement Payments”) to Aronson and Gorton, as more fully described in the Aronson/Gorton Settlement Agreement.

5.                                       As of the date of this agreement, ACTC has a net liability to Group in the amount of $599,581 (“ACTC Obligations”), consisting of a Note Payable of $1,000,000, and related accrued interest of $381,877, owed to Group by ACTC, offset by an Intercompany Receivable due to ACTC from Group in the amount of $782,295.  Additionally, as more fully described above, ACTC has agreed to (i) extinguish in full

2

Group’s obligations of indebtedness to Aronson and Gorton, and (ii) make the Settlement Payments to Aronson and Gorton of $332,524 cash and $600,000 in Notes Payable.  In addition, as part of the settlement, ACTC has issued a Warrant to purchase 422,727 shares of ACTC Common Stock at $2.20 per share, resulting in a Black Scholes charge to ACTC of $469,966.  The aggregate amount related to Settlement Payments, including cash, notes and Black Scholes value of warrants issued (“Group Obligations”) is $1,402,490. As summarized in Exhibit A to this agreement, there is an existing intercompany debt owed to ACTC by Group of $802,909, comprised of the difference between the Group Obligations and the ACT Obligations (such difference hereinafter referred to as the “Inter-Company Balance”), and, each Party desires to settle the Inter-Company Balance in conjunction with the settlement of the Bridge Note Litigation.

6.                                       Therefore, the Parties desire to provide for the extinguishment of the Inter-Company Balance in accordance with the terms of this Agreement.
