Exhibit 10.16

AMENDED AND RESTATED WARRANT AGREEMENT

This Amended and Restated Warrant Agreement (this “Agreement”), is made and entered into this 8th day of September, 2003, by and between DIGITAS INC., a Delaware corporation (the “Company”) and Highbridge International LLC, a Cayman Island limited liability company (the “Purchaser”).

RECITALS

1.    Bronner Slosberg Humphrey Co., a Massachusetts business trust (“BSH”), Positano Partners Ltd. (“Positano”), a Bermuda exempt company, and other parties named therein entered into a Recapitalization Agreement dated November 28, 1998 (the “Recapitalization Agreement”), pursuant to which BSH issued Positano a warrant to purchase an aggregate of 15,000 shares of beneficial interest in BSH (the “Original Warrant”).

2.    The Company is the successor-in-interest to BSH and has assumed all of BSH’s rights and obligations under the Original Warrant.

3.    The Original Warrant was adjusted from 15,000 to 900,000 shares to give effect to a sixty for one stock split.

4.    In January 2000, the Company repurchased a portion of the Original Warrant representing 120,000 shares from Positano.

5.    On March 13, 2000, Positano assigned its rights under the Original Warrant to three of its affiliates (the “HF Entities”), and in connection therewith, the Company issued a separate warrant to each of the HF Entities (the “HF Warrants”).

6.    The Purchaser agreed to purchase each of the HF Warrants pursuant to that certain Warrant Purchase Agreement, dated June 26, 2003.

7.    The parties to the HF Warrants desire to amend such warrants to clarify the parties’ relationship and to combine the three separate warrant agreements into one agreement granting the Purchaser the right to purchase the Digitas Shares on the terms and subject to the conditions set forth below.
