Business

. A leading provider of capacity-optimized storage appliances for disk-based backup and network-based

disaster recovery.

. Appliances reduce the storage of redundant copies of data and associated storage costs within enterprises

and are an alternative to tape-based protection storage systems.

Industry

. In 2007, revenues from the tape-based storage market are expected to be approximately $4.7 billion based

on estimates from Freeman Reports, an industry research firm.

. Storage solutions address protection storage requirements with low operating costs, ease of use, high

performance, reliability and compatibility with leading enterprise backup software.

Sales

Sells appliances through a network of channel partners and a direct sales force.

. As of March 31, 2007, had over 100 channel partners and DDUP appliances had been purchased by over

750 enterprises worldwide.

. In each of the year ended December 31, 2006 and the three months ended March 31, 2007, 85% of

revenue was generated by sales through indirect channels

Compression technology

DDUP's disk-based appliances combine DDUP's Global Compression technology with industry standard

components to enable dramatic reductions in the amount of stored backup data.

. Global Compression technology incorporates a process called data deduplication, which avoids storing

redundant copies of data while writing data to disk.

. When used to deduplicate a single data set over 20 weeks of regular backup storage events, DDUP's

appliances are designed to achieve a range of data compression of approximately 10x to 30x.

. The actual range of data compression obtained by customers depends on the frequency of full backup

events, the length of time backup data is retained and the redundancy of the backup data.

. Through deduplication, DDUP's appliances enable enterprises to cost-effectively utilize WAN vaulting, a

process by which enterprises replicate backup data offsite using a wide area network, or WAN.

. DDUP's appliances also provide advanced levels of data protection that are designed to ensure that

backup data is accurate and recoverable.

International

. Expects growth in international markets to be a significant factor contributing to revenue growth in future

periods.

. International revenue accounted for approximately 32% and 28% of total revenue in the year ended

December 31, 2006 and the three months ended March 31, 2007, respectively.

. However, over time, DDUPexpects international revenue to increase in absolute dollars and as a

percentage of total revenue.

Three Months Ended March 31, 2007 Compared to the Three Months Ended March 31, 2006:

> Product revenue increased $12.5 million, from $5.4 million in the three months ended March 31, 2006 to

$17.9 million in the three months ended March 31, 2007,

. Due to an increase in the number of units sold to new and existing customers, an increase in the number of

sales personnel, an increase in the number of our channel partners, and the introduction of new products.

. These products, which have higher capacity and higher performance, were sold at higher average sales

prices. DDUP expects to continue to release new products with higher capacity and higher performance.

> Support and services revenue increased $2.0 million, from $172,000 in the three months ended March 31,

2006 to $2.1 million in the three months ended March 31, 2007.

. This increase was the result of increased product sales and, to a lesser extent, the renewal of support and

services contracts by existing customers.

. Substantially all customers purchase support and services contracts when they purchase appliances..

Competition

The protection storage market is highly competitive and is driven by rapidly changing technology.

. In addition to competing with traditional providers of tape-based storage systems, such as Sun

Microsystems, Inc. and Quantum Corporation, DDUP

. Competes with other established storage companies such as EMC Corporation and Network Appliance,

Inc., and to a lesser extent Hitachi Data Systems Corporation, Hewlett-Packard Company and International

Business Machines Corporation, that offer a variety of different protection storage products.

. Some of our competitors sell, or have announced plans to sell, capacity-optimized storage products that

compete directly with DDUP appliances.

. Also competes with a number of emerging hardware and software companies that may become more

significant competitors in the future. In addition, in certain segments of the market, we may compete with

WAN acceleration and backup software providers that incorporate deduplication capabilities in their

products.

Use of $78mm in IPO proceeds

. expansion of domestic and international sales and marketing activities, including hiring additional

personnel and growing the network of channel partners;

. investment in research and development to enhance the capacity and performance of appliances;

. deployment of products and technology into other sectors of the storage market; and

. other corporate opportunities that may arise in the future.

Business

. A leading global high technology filtration company that develops, manufactures and markets specialized

microporous membranes used in separation and filtration processes.

. Manufactures products at facilities in North America, Europe and Asia.

Two business segments

(i) the energy storage segment, which accounted for approximately 72% of fiscal 2006 net sales; and

(ii) the separations media segment, which accounted for approximately 28% of our fiscal 2006 net sales.

Three months ended March 31, 2007 compared with the three months ended April 1, 2006

> Net sales for the three months ended March 31, 2007 were $129.8 million, an increase of $14.5 million,

or 12.6%, from the three months ended April 1, 2006.

. Energy storage sales for the three months ended March 31, 2007 were $93.9 million, an increase of $10.7

million, or 12.9%.

. The increase in energy storage sales was primarily due to higher lead-acid and lithium battery separator

sales volume, higher average sales prices for lead-acid battery separators and the positive impact of

dollar/euro exchange rate fluctuations of $2.5 million.

. Lead-acid separator volume growth of 6.6% was driven by the increasing size of the automotive market,

particularly in Asia, and the trend of conversion from alternative separator materials to superior

performing polyethylene-based separators.

. In addition, average sales prices increased due to global price increases implemented in the three months

ended December 30, 2006 to offset higher raw material and energy costs. The increase in sales volumes of

15.3% for lithium battery separators was driven by strong demand for consumer electronic products and

expanding applications for lithium batteries.

> Separations media sales for the three months ended March 31, 2007 were $35.9 million, an increase of

$3.8 million, or 11.8% from the same period in the prior year.

. The increase in separations media sales was due to higher sales of industrial and specialty filtration

products and the positive impact of dollar/euro exchange rate fluctuations of $2.2 million.

. The 29.8% growth in sales of industrial and specialty filtration products was due to continued growth in

demand for high performance filtration applications.

. In total, hemodialysis sales for the three months ended March 31, 2007 were comparable to the three

months ended April 1, 2006. Synthetic membrane sales volumes increased due to continued market growth

for synthetic membranes. The increase in synthetic membrane sales was offset by the decline in cellulosic

membrane sales.

. During 2006, produced sufficient quantities of cellulosic membranes to meet our customers' needs and

ceased production of cellulosic membranes. Expects to sell the majority of our remaining quantities of

cellulosic membranes during 2007.

Competition

> Within the energy storage segment, primary competitors in the market for membrane separators used in

lead-acid batteries for transportation and industrial applications are Entek International LLC ("Entek") in

North America and Europe and Nippon Sheet Glass Co., Ltd. in Japan. In addition, we have a number of

smaller competitors in South Korea, Indonesia, China, and North America.

. Also competes with Asahi Kasei Chemicals Corporation, Tonen Chemical Corporation (a subsidiary of

ExxonMobil) and Ube Industries Limited as well as a number of smaller competitors elsewhere in Asia in

the market for membrane separators used in lithium batteries.

> Within the separations media segment, competes primarily with Fresenius Medical Care, Gambro AG,

Asahi Kasei Medical Co., Ltd. and Toyobo Co. Ltd. for membranes used in dialysis.

. In addition, we compete primarily with Terumo Medical Corp. in the blood oxygenation market and Asahi

Kasei Medical Co., Ltd. and Fresenius Medical Care in the plasmapheresis market.

. Also within the separations media segment, our industrial and specialty filtration business competes

across multiple markets and applications; principal competitors include Pall Corporation, Millipore

Corporation, Koch Membrane Systems (a division of Koch Industries), Norit B.V., and Dainippon Ink and

Chemicals, Inc. Product innovation and performance, quality, service, utility and cost are the primary

competitive factors, with technical support being highly valued by the largest customers.
