"The move to NASDAQ is a significant milestone for Aradigm and underscores our
commitment to grow the value of our Company and broaden our shareholder base,"

build on the positive momentum generated throughout this year with the start
of our ORBIT-3 and ORBIT-4 Phase III clinical trials with Pulmaquin^® for
bronchiectasis and our recent QIDP designation from FDA for Pulmaquin for this
disease, we are very pleased to begin trading on NASDAQ. We believe it will
provide more liquidity for our shareholders. The strong fundamentals of the
Company together with the increased visibility that NASDAQ will provide should
assist us in maximizing shareholder value over the short and long term."

"We welcome Aradigm Corporation to the NASDAQ family of listed healthcare
companies," commented Robert H. McCooey, Jr., Senior Vice President of New

About Pulmaquin

Ciprofloxacin, available in oral and intravenous formulations, is a widely
prescribed antibiotic. It is used to treat acute lung infections and is often
preferred because of its broad-spectrum antibacterial activity against various
bacteria, such as Pseudomonas aeruginosa. Pulmaquin is a dual release
formulation composed of a mixture of liposome encapsulated and unencapsulated
ciprofloxacin. It is being evaluated in two Phase III studies to determine its
safety and effectiveness as a once-a-day inhaled formulation for the chronic
treatment of non-CF BE. The ORBIT-3 study began dosing patients in April 2014
and ORBIT-4 will begin dosing patients in 1H 2014.

Pulmaquin has been extensively tested through preclinical studies and a Phase
IIb study (ORBIT-2). Previous studies have demonstrated no significant
clinical safety concerns.

Aradigm has been granted orphan drug designations for inhaled liposomal
ciprofloxacin as well as for inhaled free ciprofloxacin for non-CF
bronchiectasis in the U.S. In addition, the U.S. Food and Drug Administration
(FDA) has designated Pulmaquin as a Qualified Infectious Disease Product
(QIDP). The QIDP designation is granted for treatment of non-cystic fibrosis
bronchiectasis (non-CF BE) patients with chronic lung infections with
Pseudomonas aeruginosa.

In 2013, Aradigm granted an exclusive, world-wide license for the Company’s
inhaled liposomal ciprofloxacin product candidates for the indication of
non-CF BE and other indications to Grifols S.A. More information on the terms
of this license may be found in the Company’s Annual Report on Form 10-K for
the year ended December 31, 2013 filed with the SEC on March 13, 2014.
