Dear Nanostone Customers:
The purpose of this letter is clarify the history of acquisitions as they relate to the Rochem brand products and Nanostone Water Inc. There have been many transactions throughout the history of this product line that have complicated the
use of the name and past references. Hopefully this outline will provide facts that will enable effective marketing going forward.
In 1997 Rochem RO Wasserbehandlung GmbH sold the Disk Tube technology to Pall Corporation. In that transaction the company and name of Rochem remained a business. Subsequent to the sale Rochem RO Wasserbehandlung GmbH launched the Spacer
Tube product to directly compete with the Disk Tube technology.
In December 2014, UAC Finance, a wholly owned entity of True North Venture Partners (TNVP), acquired the original Rochem RO Wasserbehandlung Spacer Tube technology and certain Disk Tube related assets from Ultura (Oceanside). The assets
acquired included, but were not limited to:
The production, office equipment and inventory at leased facilities in Carlsbad and Oceanside California
The intellectual property related to Disk Tube and Spacer Tube technology (Transferred from Ultura RO Property GmbH in October 2014).
Domain names such as www.rochem.com 
Trademarks for ROCHEM registered in Germany and the UK as well as Rochem Spacer Tube Module registered in Germany.
Intangible items such as the right, reference, title, and interest in all goodwill of the business, catalogues, customer lists, advertising materials, trade secrets, knowhow, proprietary technology, processes, formulae, methodologies,
and all related documentation and media describing the manufacturing of products included in the sale.
In December 2014 after the acquisition of the Ultura (Oceanside) Inc. assets, TNVP transferred ownership of UAC Finance to Nanostone Water, Inc.
In December 2014 after all of the transactions were finalized, UAC Finance, officially changed its name to Sepro Membranes, Inc（a sub-company of Nanostone Water）
Following these transactions Nanostone would promote the Nanostone brand going forward, and decided to abandon the Rochem trademark held in Germany later.
We understand that certain companies previously associated with the past Rochem businesses are claiming they are the owner of the intellectual property. We, through Sepro Membranes Inc, are the legal owners without any liens or
encumbrances of all of the active intellectual property for the spacer tube technologies, all the product reference, and we will defend any infringement on our intellectual property. 
We hope that this letter provides you with complete and absolute clarity regarding our ownership of ST and DT product lines. We remain available and are happy to answer any additional questions that you or your customers may have.
尊敬的客户
这封信的目的是澄清收购的历史，因为他们涉及到Rochem品牌、产品和Nanostone公司。在这个产品线的历史上发生了多次交易从而造成名称使用和过往业绩的复杂化。 希望这个澄清能把事实说清楚，有助于有市场推广。
