EMERGENT RESPIRATORY PRODUCTS, INC. ACQUISITION BY KING SYSTEMS CORPORATION

IRVINE, CALIF. -April 16, 2007 - Emergent Respiratory Products, Inc. President and Chief Executive Officer, Hans Gregory Wood, announced today a two-step acquisition of the company by King Systems Corporation ("King Systems"), an Indiana corporation and subsidiary of Bespak, PLC, a public company listed on the London Stock Exchange ("Bespak").

King Systems invested $3 million on April 13, 2007 for a 51% equity stake in Emergent. This initial investment will be used to increase Emergent's pre-hospital sales organization and leverage the opportunities from King Systems and Bespak's range of proprietary airway management products. The remaining 49% of the Company will be acquired by King Systems from Emergent shareholders between 2009 and 2011, upon exercise of an option by King Systems at a pre-determined multiple of Emergent's profits, but in any event subject to a maximum deferred consideration of $35 million.

Emergent's patented Continuous Positive Airway Pressure (CPAP) products offer a range of benefits over competing products. CPAP is non-invasive and supplies oxygen "on demand" to conscious, spontaneously breathing patients.

The acquisition of Emergent is highly complementary to King Systems' anesthesia and airway management business. Mr. Wood will continue as Chief Executive Officer of Emergent through the option exercise period.

CPAP, which is indicated for patients with congestive heart failure, pulmonary edema, and asthma attacks, is an alternative to intubating patients while they are transported to the hospital, thus potentially reducing the length and cost of hospital stays, reducing the risk of infection, and improving patient outcomes. The CPAP market is small, but is growing rapidly in the U.S. and Europe.

Mark Throdahl, Bespak's Chief Executive, commented, "We are delighted to announce the acquisition of Emergent, continuing our strategy of building Bespak around high-growth markets and technologies that help people to breathe. Emergent brings another growth platform to Bespak's portfolio of growing businesses. It also expands our market reach from anesthesiology to emergency medicine not only for CPAP, but also for King Systems' existing airway products."

Mr. Kevin Burrow, King Systems' President, commented, "Emergent brings to King Systems expertise in the pre-hospital market that will enable us to successfully deliver life saving airway management products to the pre-hospital care giver. It is our goal to make a difference when it truly matters. Combining the expertise of both companies will help us achieve this goal. We are confident this relationship will help us bring new product opportunities to the pre-hospital market, as well as acute care facilities."

Mr. Wood commented, "We are excited about joining King Systems Corporation and expanding the product offering to the pre-hospital and EMS market. The additional resources and support from King Systems will only broaden the impact of pre-hospital CPAP and airway solutions from Emergent. I look forward to offering our current and potential customers a total airway solution as we increase the market awareness."

Emergent Respiratory Products, Inc. develops, manufactures, and markets a patented suite of non-invasive ventilation therapy devices that, through a leap in engineering, not only defines the state of the art but is helping to expand the application and demand for these devices.

Bespak PLC is a leader in medical devices for inhaled drug delivery and anesthesia. Bespak develops and manufactures metered dose inhaler valves, actuators, compliance aids, and dry powder drug delivery systems for the pharmaceutical industry.
