================================================================================

RECENT DEVELOPMENTS

On December 13, 2002, we and Eli Lilly and Company expanded our collaboration
for the development of inhaled formulations of insulin based on our AIR(R)
pulmonary drug delivery technology. These amendments to the collaboration follow
the achievement of development milestones relating to clinical progress, and
scale-up and manufacturing activities for our insulin dry powder aerosols and
inhalers.

Pursuant to a Stock Purchase Agreement, dated December 13, 2002, Lilly agreed to
purchase $30 million of our newly issued convertible preferred stock. We will
fund the joint development program for inhaled insulin during calendar years
2003 and 2004. In addition, the royalty rate payable to us based on revenues of
potential inhaled insulin products has been increased. Lilly has the right to
exchange the preferred shares for a reduction in the royalty rate payable to us.
The preferred stock is convertible into our common stock at market price at our
option and upon filing of a new drug application with the U.S. Food and Drug
Administration for a pulmonary insulin product. The collaboration cannot
terminate without cause until January 2005. We will register for resale all
shares of our common stock issued upon conversion of the preferred stock.


We entered into a license agreement with GlaxoSmithKline in May 2000 for the
use of our AIR technology in the development of multiple product candidates for
indications in four respiratory disease categories. Glaxo has not met all of
its obligations to develop product candidates under two respiratory disease
categories in a timely manner and, under the terms of the license agreement,
those two respiratory disease categories automatically reverted to us on
November 30, 2002. On December 16, 2002, Glaxo delivered to us notice that it
intended to exercise its right to terminate the license agreement by providing
us with 60 days' prior written notice, therefore the remaining two respiratory
disease categories will revert to us on February 14, 2003.

ITEM 20.   INDEMNIFICATION OF DIRECTORS AND OFFICERS


Sections 1741 through 1750 of the Pennsylvania Business Corporation Law of 1988,
as amended, permits, and in some cases requires, the indemnification of
officers, directors and employees of the Registrant. Section 5.1 of the
Registrant's By-Laws provides that the Registrant shall indemnify any director
or officer of the Registrant against expenses (including legal fees), damages,
punitive damages, judgments, penalties, fines and amounts paid in settlement,
actually and reasonably incurred by him or her, to the fullest extent now or
hereafter permitted by law in connection with any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, brought or threatened to be brought against him or her, including
actions or suits by or in the right of the Registrant, by reason of the fact
that he or she is or was a director or officer of the Registrant or any of its
subsidiaries or acted as a director or officer or in any other capacity on
behalf of the Registrant or any of its subsidiaries or is or was serving at the
request of the Registrant as a director, officer, partner, fiduciary or trustee
of another corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise.



Section 5.2 of the Registrant's By-Laws provides that the Registrant will pay
the expenses (including attorneys' fees and disbursements) actually and
reasonably incurred in defending a proceeding on behalf of any officer or
director entitled to indemnification in advance of the final disposition of such
proceeding upon receipt of an undertaking by or on behalf of such officer or
director to repay such amount if it shall ultimately be determined that such
officer or director is not entitled to be indemnified by the Registrant as
authorized. The financial ability of such officer or director to make such
repayment shall not be prerequisite to the making of an advance.

ITEM 22.   UNDERTAKINGS

Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers and controlling persons of the Registrant
pursuant to the foregoing provisions or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.



                                      II-6


The undersigned registrant hereby undertakes to supply by means of a

GlaxoSmithKline ("Glaxo"), we issued and sold 160,030 shares of our common stock
to an affiliate of Glaxo for an aggregate purchase price of $5.0 million, in a
transaction exempt from the registration requirements of the Securities Act
pursuant to Section 4(2) of the Securities Act. We reasonably believed Glaxo was

In December 2002, pursuant to a Stock Purchase Agreement, we issued and sold to
Eli Lilly and Company ("Lilly") 3,000 shares of our newly issued convertible
preferred stock for an aggregate purchase price of $30 million, in a transaction
exempt from the registration requirements of the Securities Act pursuant to
Section 4(2) of the Securities Act. The preferred stock is convertible into our
common stock at market price at our option and in certain circumstances. We
