Dear Colleague

We are delighted to publish a further issue of "MEMBRANE LETTER", our industry-wide newsletter. In this issue we endeavour to show that, despite
the advent of new membranes, HEMOPHAN^®, a veteran product, is still the prime membrane of choice in many aspects of dialysis.

Feedback from recipients of "MEMBRANE LETTER" has been very positive indeed

and we hope to continue publishing what we believe is a helpful resource of information for the dialysis community.
In fact, Membrana, being the largest independent membrane manufacturer world-wide, is in an unbiased position, having neutral insight into almost any issue in haemodialysis.

So that we can keep generating interesting material for the newsletter,
it is important for us to receive your comments on the content of past and future issues. I would be glad to hear about what you did or did not like, how can we improve it and what topics would you like to see covered in the coming issues of this newsletter? In that regard
I would ask that you complete the form on the reverse of the cover letter and
fax it back to us.

We truly rely on your feedback to help us provide the best possible information to assist you in caring for your dialysis patients, so please take the time to let us know what you would like to see in the future.

Yours sincerely

Dr. Ulf Seidel
