(1) Represents the total number of shares of Callable Common Stock of Spiros
Development Corporation II, Inc. ("SDCII Common Stock") currently outstanding.
Such shares were originally traded as units, 156,250 of which are currently held
by the Dura Pharmaceuticals, Inc. ("Dura") Deferred Compensation Plan. Each unit
consisted of one share of SDCII Common Stock and one warrant (the "Dura
Warrants") to purchase one-fourth of one share of Common Stock of Dura. On
December 31, 1999, the SDCII Common Stock and the Dura Warrants began trading
separately. Dura has the option to purchase all, but not less than all, of the
SDCII Common Stock outstanding at the time of the exercise of such option. As a
result, the above reported number of shares of SDCII Common Stock is subject to
change, based upon the total number of SDCII Common Stock outstanding at the
time of exercise, if such option is exercised.

Securities and Exchange Commission (the "Commission") on January 2, 1998 and

On February 14, 2000, Dura made an offer to the board of directors
of SDCII to acquire all of the outstanding SDCII Common Stock, at a price of
$12.50 per share. Dura's proposed acquisition would be completed by means of
a tender offer followed by a merger. No offer is being made to stockholders
of SDCII at this time. The Dura Warrants will remain outstanding and will not
be included in the offer. A copy of Dura's offer letter to the Board of
Directors of SDCII is attached hereto as Exhibit 99.1 and the press release

February 14, 2000
Board of Directors
Spiros Development Corporation II, Inc.
7475 Lusk Boulevard
San Diego, CA 92121
Gentlemen:
Dura Pharmaceuticals, Inc. ("Dura") is pleased to submit to
you this offer to acquire Spiros Development Corporation II, Inc. ("Spiros") at
a cash price of $12.50 per share, net to each holder (the "Offer Price"), of
Callable Common Stock, par value $0.001 per share, of Spiros (the "Spiros Common
Stock"). The acquisition would be accomplished by means of a tender offer
followed by a merger at the Offer Price. Our offer is subject to the execution
of a satisfactory definitive merger agreement. We will provide a draft of the
merger agreement to Skadden, Arps, Slate, Meagher & Flom LLP, counsel for the
special committee of independent directors of Spiros, within the next few days.
Dura believes the Offer Price is fair to the holders of Spiros
Common Stock, as it represents a premium of 20% over the average closing price
of the Spiros Common Stock for the past ten trading days. In establishing the
Offer Price, we have considered, among other things, the technical, clinical and
regulatory risks associated with completing the development programs for Spiros
Beclomethesone-TM- and Spiros Budesonide-TM-, the two remaining products under
development by Spiros that Dura would continue to develop upon acquisition of
the Spiros Common Stock, the significant costs required to complete the
development programs for these products, the market potential for these products
and the associated risks and costs of commercializing these products. We would
be pleased to discuss these issues with you and your advisors.
This offer has been approved by our board of directors and may
be withdrawn at any time prior to acceptance by you. We would like to enter into
the merger agreement no later than February 25, 2000 and complete the
acquisition as soon as possible. Dura, its financial advisor and legal counsel
are prepared to meet with you at any time to negotiate the terms of the merger
agreement.
We look forward to hearing from you.
Very truly yours,
DURA PHARMACEUTICALS, INC.
/s/ CAM L. GARNER

DURA PHARMACEUTICALS OFFERS TO ACQUIRE
SPIROS DEVELOPMENT CORPORATION II
DURA ANNOUNCES INTENT TO DISCONTINUE ALBUTEROL SPIROS-TM- DEVELOPMENT PROGRAM
San Diego, CA - February 14, 2000 - Dura Pharmaceuticals, Inc. (Dura)
(Nasdaq NNM: DURA) today announced that it has made an offer to the board of
directors of Spiros Development Corporation II, Inc. (SDCII) (Nasdaq NNM: SDCO)
to acquire all of the outstanding callable common stock of SDCII at a cash price
of $12.50 per share or total cash consideration of approximately $79.0 million.
The Dura warrants (Nasdaq NNM: DURAW) that separated from the SDCII callable
shares on January 1, 2000 are not affected by Dura's offer. In the offer, Dura
proposed to complete the acquisition by means of a tender offer followed by a
merger at the same $12.50 price per share. The offer is subject to the
negotiation and execution of a satisfactory merger agreement, but is not subject
to financing. SDCII previously informed Dura that it had formed a committee of
independent directors to consider the company's strategic alternatives,
including any transactions proposed by Dura.
"This offer represents significant premiums to the recent trading
prices for SDCII's callable common stock and SDCII's available cash per share
and we intend to work diligently to reach a definitive agreement with SDCII,"
said Cam L. Garner, Dura's Chairman and Chief Executive Officer. "We believe a
successful acquisition of SDCII will remove any uncertainty and confusion
surrounding Dura's relationship with SDCII, resulting in part from SDCII's
current cash position and cash burn, and the pending pronouncement issued by the
Financial Accounting Standards Board covering consolidations. The consolidation
of SDCII into Dura will eliminate the earnings impact of SDCII contract revenue
net of related income tax expense. We believe the acquisition of SDCII, as we
are proposing, will enhance Dura shareholder value for the long-term."
As previously announced, Dura, on behalf of SDCII, has been addressing
chemistry, manufacturing and control (CMC) issues for Albuterol Spiros-TM- and
at the same time evaluating the market potential and financial return from this
product candidate. Dura has concluded its evaluation, and upon successful
completion of the proposed acquisition of SDCII, Dura plans for commercial
reasons to discontinue development of albuterol in the current Spiros-Registered
Trademark- platform. The Company stated that the full market value of the
existing respiratory products is resident in the two steroids in development and
that development activity on these two products, Beclomethasone Spiros-TM- and
Budesonide Spiros-TM-, is moving ahead.
<PAGE>
"Although we plan to discontinue the Albuterol Spiros-TM- program, we
continue to have confidence in the Spiros-Registered Trademark- platform and
remain very excited about the opportunity with the steroid products and the
successful development of Beclomethasone Spiros-TM- and Budesonide Spiros-TM-,"
stated David S. Kabakoff, Ph.D., President of Dura Technologies. "The clinical
programs for the two steroids are continuing as patient enrollment for the
Beclomethasone Spiros-TM- reliability study was recently completed. The
Spiros-Registered Trademark- clinical programs and regulatory reviews, if
successful and assuming the acquisition of SDCII, should allow for the two
steroid product candidates to add significantly to Dura's product revenues
beginning in the 2002 and 2003 timeframe, respectively. In addition, we are
currently evaluating additional candidates for development in the
Spiros-Registered Trademark- platform with a goal of commencing development on a
selected compound in 2000. We are also actively pursuing partnerships for local
and systemic delivery of products that could benefit from delivery in the
Spiros-Registered Trademark- platform.
Dura Pharmaceuticals, Inc. is a San Diego based developer and marketer
of prescription pharmaceutical products for the treatment of allergies, asthma,
pneumonia and related respiratory conditions. Dura focuses on the U.S.
respiratory market because of its size and growth opportunities through two
major strategies: (1) acquiring prescription pharmaceuticals and/or businesses
developing or marketing such pharmaceuticals to support its marketing presence
in high-prescribing physicians' offices and/or the hospital market, and (2)
developing Spiros-Registered Trademark-, a pulmonary drug delivery system for
both topical and systemic delivery of medications.
Except for the historical and factual information contained herein, the
matters discussed in this press release may contain forward-looking statements
which involve risks and uncertainties, including the completion of the
acquisition of SDCII, Inc. on acceptable terms, the timely initiation and
successful completion of the clinical trial programs for the Spiros-Registered
Trademark- products, the ability to obtain adequate funding to complete the
clinical trial programs for the Spiros-Registered Trademark- products, the
timely FDA approval of the Spiros-Registered Trademark- products, if at all, the
dependence on third parties for manufacturing and development, the
competitiveness of the pharmaceutical industry, risks inherent in merger and
acquisition transactions and other risks detailed from time to time in Dura's
filings with the Securities and Exchange Commission. Actual results may differ
materially from those projected. Any forward-looking statements represent Dura's
judgment as of the date of this release. Dura disclaims, however, any intent or
obligation to update these forward-looking statements. Further information about
