Monday May 18, 2009

– Alliance Establishes Partnership with Leading Renal Products Company in Asia
– Collaboration Expected to Yield Gross Margin Improvement and Accelerate Path to Profitability
– Financing Provided in Connection with Alliance Significantly Improves Balance Sheet and Cash Flow

LAWRENCE, Mass., May 18 /PRNewswire-FirstCall/ — NxStage Medical, Inc. (Nasdaq: NXTM), a leading manufacturer of innovative dialysis products, today announced its plans to form a strategic business alliance with Asahi Kasei Kuraray Medical, (Asahi), a leading medical supply company headquartered in Japan. The signed agreements between the partners are multi-faceted, but most importantly leverage NxStage’s production expertise in its existing dialyzer manufacturing facility in Germany and Asahi’s high performance polysulfone hollow-fiber membranes. In addition, Asahi will provide NxStage with $40 million of debt financing to pay off its entire debt obligation owed under its GE credit facility.

The alliance combines the complementary strengths of the two partners in innovative and competitive technology, product development, and market presence. This transaction is expected to enable both companies to accelerate their global growth strategy through mutual synergy.

Elements of the Alliance:

Dialyzer Assembly

NxStage will assemble and label its dialyzers for Asahi under the Asahi name brand at NxStage’s facilities in Germany. Asahi will sell the dialyzers exclusively in Asia and non-exclusively in rest of world; however, NxStage is retaining all its rights in North America. When Asahi desires additional capacity from NxStage, Asahi shall fund the construction of a new facility to provide both parties with additional dialyzer production capacity. The new facility would be owned by Asahi and operated by NxStage. By collaborating in dialyzer assembly, both parties expect to realize cost savings.


NxStage will grant Asahi a royalty-free license to its production technology to make and sell NxStage’s current dialyzer design exclusively in Asia and non-exclusively in rest of world; however, NxStage is retaining all its rights in North America. NxStage will also license certain rights for Streamline blood tubing set technology to Asahi under similar conditions. Any improvements obtained through the combination of the dialyzer manufacturing or bloodline technologies of the two companies are to be mutually cross-licensed on similar terms.

Hollow-Fiber Membrane Supply

Asahi will supply its high performance polysulfone hollow-fiber membrane to NxStage for NxStage branded products in North America. Consistent with our obligations, NxStage will continue to purchase fiber from its current supplier for NxStage System One filters.

Financial Backing

Asahi will provide NxStage with $40 million of debt financing on competitive terms, including an 8% interest rate (NxStage’s current rate under the GE facility is 11%), with 50% of the interest deferred to maturity. The four year loan includes no financial covenants and the debt may be prepaid by NxStage without penalty at anytime. However, if the loan goes to maturity, Asahi will have the option, subject to certain limitations, to be repaid in shares of NxStage common stock. The debt includes a balloon principal repayment and will be secured by NxStage assets other than cash, accounts receivables, inventory or field equipment. The debt agreement also provides NxStage the ability to borrow up to $40 million from other lenders. Part of the proceeds will be used to pay off NxStage’s $28 million owed under its GE credit facility plus prepayment and other transaction fees. Remaining proceeds will be used for operating purposes.

Other Collaboration

Joint business development will be pursued in areas as mutually agreed upon between the two companies. Possible areas include the development of therapeutic apheresis systems using NxStage’s technology, collaboration on raw materials sourcing, and possible joint hemodialysis systems development programs. NxStage also granted Asahi a right of first negotiation for exclusive distribution rights of the NxStage System One in Asia.

Our relationship with one of the largest renal product companies in Asia is an important step for NxStage as we extend our commercial operations globally, stated Jeffrey H. Burbank, Chief Executive Officer of NxStage Medical. I believe this transaction will accelerate our path to profitability. We are enthusiastic that this relationship with Asahi will deliver significant value to our shareholders, strengthen our balance sheet, and create growth opportunities in 2010 and beyond.

NxStage has proven its ability to produce high-performing, low-cost dialyzers in the competitive renal products market, stated Yasuyuki Yoshida, Chief Executive Officer and President of Asahi Kasei Kuraray Medical. We are aligning ourselves with a diversified leader in US renal care with superb products and an impressive track record. We believe this alliance leverages Asahi Kasei Kuraray Medical’s leadership position, providing us a strong and growing partner for our world class fiber technology.

The agreements with Asahi are conditioned upon NxStage obtaining a payoff letter and associated documentation from the lenders under its GE credit facility.
