Greenfield Online (SRVY) DEFA14A Additional proxy soliciting materials

Exhibit 99.4

Greenfield Online, Inc. Transaction Q&A
August 29, 2008

1.	What is the transaction?
	Today, Greenfield Online, Inc. (“Greenfield Online”) entered into an agreement with Microsoft Corporation (“Microsoft”) to be acquired for $17.50 per share in cash.
2.	Why has Microsoft entered into this agreement?
	Microsoft has agreed to acquire Greenfield Online because it believes that the Ciao comparison shopping business (“CSS”) is beneficial to its internet strategy in Europe.
	Microsoft has advised us that it will sell the ISS business to an undisclosed financial buyer that Microsoft believes to be a great partner for Greenfield, who is as enthusiastic about the prospects of the ISS business as Microsoft is about the CSS business.
3.	What is the rationale for this transaction?
	In accordance with the terms of the agreement we entered into with Quadrangle, our Board and management sought alternative proposals for the purchase of Greenfield Online. During that process, which is referred to as the “go-shop” period, Microsoft made an offer that was $2.00 higher per share than the Quadrangle offer. The Microsoft offer is not subject to any financing contingencies, nor is it contingent on Microsoft’s ability to sell the ISS business.
	The offer made by Microsoft represents a premium of approximately 13% over the Quadrangle offer and represents a premium of approximately 32% over $13.28, the closing price of our stock on June 13, 2008, the last trading day before we announced the Quadrangle agreement.
	Our Board believes this offer represents the best outcome for both our employees and our shareholders.
4.	Why did it take so long for the Company to deem this proposal superior?
	We were in active negotiations with Microsoft with regard to the merger agreement. We worked as expeditiously as possible and are pleased that we believe we have been able to reach a better outcome for employees and shareholders in this transaction.

Transaction/Financial

5.

What are the terms of the transaction?

Microsoft will acquire all of the outstanding common stock of Greenfield Online for $17.50 per share in cash, for a total equity value of approximately $486 million. The offer made by Microsoft represents a premium of approximately 13% over the Quadrangle offer and represents a premium of approximately 32% over $13.28, the closing price of our stock on June 13, 2008, the last trading day before we announced the Quadrangle agreement. Microsoft intends to acquire the shares through a two-step process, starting with a Tender Offer and then merging a Microsoft subsidiary into Greenfield Online to complete the transaction.

6.	How does Microsoft intend to finance the transaction?
	Under the terms of the agreement, Microsoft will commence a cash tender offer to purchase all of the outstanding shares of Greenfield Online.

Regulatory

7.	Are there any approvals required?
	Yes, the transaction is subject to customary closing conditions and regulatory approval in both the United States and Europe. It may also be subject to a shareholder vote.
8.	What happens next?
	Microsoft will prepare and file a Tender Offer that will ask our stockholders to tender their shares to Microsoft for $17.50 per share. If Microsoft receives 90% or more of our outstanding shares in the Tender Offer, Microsoft will complete the merger without the need for stockholder approval. If Microsoft receives less than 90% of our outstanding stock in the Tender Offer, it has the option to either purchase shares from us so that it has 90% of our outstanding stock (the “Top-Up Option”) and then complete the merger, or it can cause the Company to file a proxy and seek approval for the merger from our stockholders. There is no requirement that Microsoft exercise the Top-Up Option.
9.	When does the Company expect the transaction to close?
	We expect the transaction to close in the fourth calendar quarter of 2008.
10.	What will happen between now and when the transaction closes?
	Greenfield Online and its business segments will continue to conduct business as usual.

Management and Operations

11.	Who will hold the senior leadership positions in Greenfield Online and its business segments once the transaction is completed?
	The leadership of Ciao is a key element of this acquisition.  One of the core sources of value in all acquisitions for Microsoft — particularly Ciao — is the retention of the great people that built the company. Many key leaders of Ciao will remain when it’s part of Microsoft. Management of the ISS business has not yet engaged in discussions with the buyer of the ISS business, however, we anticipate that members of our current ISS management will remain in place after the closing.
12.	Will Microsoft or the buyer of the ISS business close any offices or other operations after the closing of the deal?
	We don’t anticipate significant relocations due to the acquisition. If necessary, relocation will be conducted in line with the legal practices of the respective country. During integration different options will be considered and you will be provided additional information once decisions have been finalized.

13.	Does that mean there will be layoffs after the closing of the deal?
	As we noted, we can’t speak for the acquirers. We are not currently aware of any layoffs planned as a result of this transaction.
14.	Will the company remain headquartered in Wilton, Connecticut?
	There are no current plans to leave its Wilton, Connecticut operations.
15.	Will the CSS business move out of its current offices in Munich (Germany), Wroclaw (Poland), Timisoara (Romania), London (United Kingdom) and Paris (France).?
	Ciao GmbH has no current plans to leave its offices in Munich (Germany), Wroclaw (Poland), Timisoara (Romania), London (United Kingdom) and Paris (France).
16.	Will CSS have to migrate its product platform to Microsoft Technologies?
	Microsoft has indicated that they want to build on the success of the current Ciao product and its technology. We are certain there are strong technology synergies that will be identified.
