style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman">On March
3, 2005, MOMS Pharmacy, Inc., a California corporation and wholly-owned
subsidiary of Allion Healthcare, Inc., entered into a letter agreement with Oris
Medical Systems, Inc., a California corporation based in San Diego. The letter
contemplates a potential software licensing arrangement under which we would
secure an exclusive license from Oris Medical to use an electronic prescription
writing system (Ground Zero Software&#8217;s LabTracker&#8482; software) that is tailored to
address the needs of physicians who treat HIV and AIDS patients. Under such a
license, we would pay Oris Medical a per patient royalty fee (for patients using
the software) that would be capped at $40 million. We believe this software
would enhance communications between our pharmacies and physicians across the
country.</FONT></DIV>

style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman">We are
not obligated to enter into this software license or to complete any other
transaction with Oris Medical. However, to secure the exclusive right to
negotiate a software license with Oris Medical, or to negotiate an acquisition
of Oris Medical, we have made, and have agreed to make, certain payments to Oris
Medical. We paid Oris Medical $100,000 and have agreed to pay them an additional
$50,000 per month in each of April, May and June 2005 to cover Oris Medical&#8217;s
monthly operating expenses. (If actual monthly operating expenses are higher, we
are not obligated to pay any higher monthly amount unless we have consented to
the excess expenses in advance.) In addition, if we complete an initial public
offering of Allion common stock, we have agreed to pay Oris Medical an
additional $1 million within three days of completion of that offering. In
exchange for these payments, Oris Medical granted us an exclusivity right
through August 31, 2005. We have the right, at our sole option, to extend this
exclusivity period for up to four successive one-month periods if we pay Oris
Medical&#8217;s monthly operating expenses for July-October 2005, up to $50,000 per
month (with any higher monthly amounts being subject to our prior
consent).</FONT></DIV>

Entry
into a Material Definitive Agreement
On March
3, 2005, MOMS Pharmacy, Inc., a California corporation and wholly-owned
subsidiary of Allion Healthcare, Inc., entered into a letter agreement with Oris
Medical Systems, Inc., a California corporation based in San Diego. The letter
contemplates a potential software licensing arrangement under which we would
secure an exclusive license from Oris Medical to use an electronic prescription
writing system (Ground Zero Software's LabTracker™ software) that is tailored to
address the needs of physicians who treat HIV and AIDS patients. Under such a
license, we would pay Oris Medical a per patient royalty fee (for patients using
the software) that would be capped at $40 million. We believe this software
would enhance communications between our pharmacies and physicians across the
country.
We are
not obligated to enter into this software license or to complete any other
transaction with Oris Medical. However, to secure the exclusive right to
negotiate a software license with Oris Medical, or to negotiate an acquisition
of Oris Medical, we have made, and have agreed to make, certain payments to Oris
Medical. We paid Oris Medical $100,000 and have agreed to pay them an additional
$50,000 per month in each of April, May and June 2005 to cover Oris Medical's
monthly operating expenses. (If actual monthly operating expenses are higher, we
are not obligated to pay any higher monthly amount unless we have consented to
the excess expenses in advance.) In addition, if we complete an initial public
offering of Allion common stock, we have agreed to pay Oris Medical an
additional $1 million within three days of completion of that offering. In
exchange for these payments, Oris Medical granted us an exclusivity right
through August 31, 2005. We have the right, at our sole option, to extend this
exclusivity period for up to four successive one-month periods if we pay Oris
Medical's monthly operating expenses for July-October 2005, up to $50,000 per
month (with any higher monthly amounts being subject to our prior
consent).
We may
not reach a definitive agreement on either a licensing or acquisition
transaction with Oris Medical.
