Item 1.01         Entry into a Material Definitive Agreement.

On January 25, 2006, deltathree, Inc. (the "Company") filed a Current Report on
Form 8-K (the "Current Report") announcing that Paul C. White, Chief Financial
Officer and Executive Vice President for Strategy, Development and Planning,
would resign from the Company in order to pursue other opportunities. As
disclosed in that Current Report, Shimmy Zimels, the Chief Executive Officer and
President, is resuming the position of principal financial officer of the
Company, upon Mr. White's departure. Mr. Zimels will also be the Company's
principal accounting officer.

In connection with Mr. White's resignation, a Separation and Release Agreement
was approved by the Compensation Committee of the Company's Board of Directors
and executed by the Company and Mr. White on February 13, 2006 (the "Separation
Agreement").

The Separation Agreement provides that Mr. White's resignation as an employee of
the Company will be effective as of February 28, 2006 (the "Separation Date"),
and that Mr. White will continue to be available to the Company in order to
ensure a smooth transition for a reasonable time period after the Separation
Date. In addition, the Separation Agreement provides that Mr. White: (i) will
continue to receive his base salary until the Separation Date; (ii) will receive
a lump sum separation payment of $90,000; (iii) will continue to participate in
the Company's benefit plans at his current levels until the earlier of the date
he enrolls in a comparable benefits plan with another employer or a period of
six (6) months after the Separation Date; (iv) will have his unvested stock
options for 21,667 shares of the Company's common stock at the exercise price of
$1.75 accelerated to vest on the Separation Date; and (v) will be entitled to
expense reimbursement due through the Separation Date. Mr. White will not be
entitled to any other payments, bonuses, severance, vacation pay or any other
amounts that are, or may be, due to him under his employment agreement with the
Company, as amended, or any other agreement. Mr. White will not be eligible for
any bonus for 2005 under the Company's 1999 Performance Incentive Plan or under
any other plan.

Under the terms of the Separation Agreement, neither the Company nor Mr. White
have any further obligations under his employment agreement with the Company, as
amended, other than the parties' obligations in connection with non-competition
and non-solicitation, confidentiality, Company property, no disparagement, the
Company's obligation of indemnification, and any additional items specifically
provided in the Separation Agreement.

The Company has agreed that in the event of Mr. White's death after the date of
the Separation Agreement, his surviving spouse shall be entitled to certain
unpaid payment amounts, as long as he did not breach of the Separation Agreement
prior to his death.

<PAGE>

Pursuant to the Separation Agreement, Mr. White has provided the Company a
general liability release of all claims arising out of his employment and
separation from the Company.

The foregoing description is only a summary of, and is qualified in its entirety
by, reference to the Separation Agreement, which is filed as Exhibit 10.1 to
this Current Report on Form 8-K.


Item 1.02         Termination of a Material Definitive Agreement.


Except as specifically provided under the terms of the Separation Agreement, the
Employment Agreement, dated April 26, 2004, as amended on October 6, 2005,
between Mr. White and the Company, has been terminated and is superseded and
nullified by the Separation Agreement.
