1.   ORGANIZATION AND BASIS OF PRESENTATION

     Inhale Therapeutic Systems ("Inhale" or the "Company") was incorporated 
in the State of California in July 1990.  Since inception, the Company has 
been engaged in the development of systems for the pulmonary delivery of 
macromolecule drug therapies for systemic and local lung applications.

     On June 23, 1998, the Company held its Annual Shareholders Meeting at 
which the Shareholders approved the Company's reincorporation in Delaware.  
The Company completed its reincorporation in Delaware on July 1, 1998.

     The accompanying unaudited condensed financial statements of Inhale 
Therapeutic Systems have been prepared in accordance with generally accepted 
accounting principles for interim financial information and the instructions 
for Form 10-Q and Article 10 of Regulation S-X.  The balance sheet as of June 
30, 1998 and the related statements of operations and cash flows for the six 
month periods ended June 30, 1998 and 1997, are unaudited but include all 
adjustments for the three and six months ended June 30, 1998 and 1997 
(consisting of normal recurring adjustments) which the Company considers 
necessary for a fair presentation of the financial position at such dates and 
the operating results and cash flows for those periods.  Although the Company 
believes that the disclosures in these financial statements are adequate to 
make the information presented not misleading, certain information normally 
included in financial statements and related footnotes prepared in accordance 
with generally accepted accounting principles have been condensed or omitted 
pursuant to the rules and regulations of the Securities and Exchange 
Commission (the "Commission").  The accompanying financial statements should 
be read in conjunction with the financial statements and notes thereto 
included in the Company's Annual Report on Form 10-K for the year ended 
December 31, 1997 as filed with the Commission.

     Results for any interim period are not necessarily indicative of results 
for any other interim period or for the entire year.

2.   COMPREHENSIVE INCOME

     Comprehensive income is equal to net income for the three and six month 
periods ended June 30, 1998 and 1997.

3.   REVENUE RECOGNITION 

     Contract revenue from collaborative research agreements is recorded when 
earned and as the related costs are incurred.  Payments received which are 
related to future performance are deferred and recognized as revenue when 
earned over future performance periods.  In accordance with contract terms, 
up-front and milestone payments from collaborative research agreements are 
considered reimbursements for costs incurred under the agreements, and 
accordingly, are generally recognized based on actual efforts expended over 
the terms of the agreements.  The Company's research revenue is derived 
primarily from partners in the pharmaceutical and biotechnology industries.  
All of the Company's research and development agreements are generally 
cancelable by the partner without significant penalty to the partner.

     Contract research revenue from two partners represented 67% of the 
Company's revenue in the six month period ended June 30, 1998.  Contract 
revenue from two partners accounted for 71% of the Company's revenue in the 
comparable period in 1997.  Costs of contract research revenue approximate 
such revenue and are included in research and development expenses.

                                                                Page 6 of 20


4.   NET LOSS PER SHARE

     Basic and diluted net loss per common share is computed in conformance 
with Statement of Financial Accounting Standards No. 128, "Earnings Per 
Share", which the Company adopted in 1997.  Accordingly, the weighted average 
number of common shares outstanding are used while common stock equivalent 
shares for stock options and warrants are not included in the per share 
calculations as the effect of their inclusion would be antidilutive.

ITEM 2.

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                   OPERATIONS

     This Management's Discussion and Analysis of Financial Condition and 
Results of Operations for the three and six months ended June 30, 1998 and 
1997 should be read in conjunction with the Management's Discussion and 
Analysis of Financial Condition and Results of Operations included in the 
Company's Annual Report on Form 10-K for the year ended December 31, 1997. 
The following discussion contains forward-looking statements that involve 
risk and uncertainties. The Company's actual results could differ materially 
from those discussed here. Factors that could cause or contribute to such 
differences include, but are not limited to, those discussed herein under the 
heading "Risk Factors" as well as those discussed in the Company's Annual 
Report on Form 10-K for the year ended December 31, 1997.

     Readers are cautioned not to place undue reliance on these 
forward-looking statements, which reflect management's analysis only as of 
the date hereof.  The Company undertakes no obligation to publicly release 
the results of any revision to these forward-looking statements which may be 
made to reflect events or circumstances occurring after the date hereof or to 
reflect the occurrence of unanticipated events.

OVERVIEW

     Since its inception in July 1990, Inhale has been engaged in the 
development of a pulmonary system for the delivery of macromolecules and 
other drugs for systemic and local lung applications.  The Company has been 
unprofitable since inception and expects to incur significant and increasing 
additional operating losses over the next several years primarily due to 
increasing research and development expenditures and expansion of late stage 
clinical and early stage commercial manufacturing facilities.  To date, 
Inhale has not sold any products and does not anticipate receiving revenue 
from product sales or royalties in the near future.  For the period from 
inception through June 30, 1998, the Company incurred a cumulative net loss 
of approximately $44.7 million.  The sources of working capital have been 
equity financings, financings of equipment acquisitions, interest earned on 
investments of cash, and payments received under research and development 
contracts.

     Inhale typically has been compensated for research and development 
expenses during initial feasibility work performed under collaborative 
arrangements. Inhale's strategy is to enter into development contracts with 
pharmaceutical and biotechnology corporate partners after feasibility is 
demonstrated. Partners that enter into collaborative agreements will pay for 
research and development expenses and may make payments to Inhale as it 
achieves certain key milestones. Inhale expects to receive royalties from its 
partners based on revenues received from product sales, and to receive 
revenue from the manufacturing of powders and the supply of devices.  In 
certain cases, the Company may enter into collaborative agreements under 
which the Company's partners would manufacture or package powders or supply 
inhalation devices, thereby potentially limiting one or more sources of 
revenue for the Company.  To achieve and sustain profitable operations, the 
Company, alone or with others, must successfully develop, obtain regulatory 
approval for, manufacture, introduce, market and sell products utilizing its 
pulmonary drug delivery system.  There can be no assurance that the Company 
can generate sufficient product or contract research revenue to become 
profitable or to sustain profitability.

RESULTS OF OPERATIONS

     Revenue in the second quarter of 1998 was $6.7 million compared to $4.0 
million in the second quarter of 1997, an increase of 68%.  Revenues for the 
six months ended June 30, 1998 were $10.5 million as compared to 

                                                                Page 7 of 20


$7.1 million for the six months ended June 30, 1997, an increase of 47%.  The 
increase in revenue for both the three and six months periods was primarily 
due to the expansion of the Company's existing collaborative agreements. 
Revenue for the first and second quarters of 1998 and 1997 was comprised of 
reimbursed research and development expenses and the amortization of the 
pro-rata portion of the up-front signing and milestone payments based on 
actual efforts expended.  Costs of contract research revenue approximate such 
revenue and are included in research and development expenses.

     Research and development expenses increased to approximately $8.6 
million in the second quarter of 1998 from $5.6 million in the corresponding 
period in 1997, an increase of 53%. Research and development expenses for the 
six months ended June 30, 1998 were $15.9 million compared to $10.2 million 
for the six months ended June 30, 1997, an increase of 55%.  The increase for 
the three and six month periods was due primarily to continued expansion of 
research activities resulting from an increase in the number of projects, 
additional hiring of scientific and development personnel, costs associated 
with the development of its commercial manufacturing facility and increased 
costs of laboratory supplies and consulting services.  The Company expects 
research, development and process development spending to increase 
significantly over the next few years as the Company expands its development 
efforts under collaborative agreements and scales up its late stage clinical 
and early commercial manufacturing facility.

     General and administrative expenses increased to $2.0 million in the 
second quarter of 1998 from $1.5 million in the second quarter of 1997, an 
increase of 33%. For the six month period ended June 30, 1998, general and 
administrative expenses were $4.0 million compared to $2.9 million in the 
comparable period of 1997, an increase of 36%.  The increase for the three 
and six month periods was due primarily to costs associated with supporting 
the Company's increased research efforts including administrative staffing, 
business development activities and marketing activities.  General and 
administrative expenses are expected to continue to increase over the next 
few years to support increasing levels of research, development and 
manufacturing activities.

     Net interest income increased to $1.1 million in the second quarter of 
1998 compared to $0.9 million in the second quarter of 1997, an increase of 
28%. Net interest income increased to $2.3 million in the six month period 
ended June 30, 1998 compared to $1.6 million for the six months ended June 
30, 1997.  Interest income was earned on larger cash and investment balances 
held by the Company in the three and six month periods ended June 30, 1998, 
compared to the same periods in 1997.  The higher cash and investment 
balances are the result of the Company receiving milestone and research 
funding payments from collaborative partners as well as the completion of a 
public offering of the Company's Common Stock in November 1997 which raised 
net proceeds of approximately $40.0 million.

LIQUIDITY AND CAPITAL RESOURCES

     The Company has financed its operations primarily through public and 
private placements of its equity securities, contract research and milestone 
payments, financing of equipment acquisitions and interest income earned on 
its investments of cash.  At June 30, 1998, the Company had cash, cash 
equivalents and short-term investments of approximately $74.3 million.

     The Company's operations used cash of $10.8 million in the six months 
ended June 30, 1998, as compared to $1.7 million used in the six months ended 
June 30, 1997.  The increase in net cash used in operations is principally 
due to the continued expansion of research activities resulting from an 
increase in the number of projects and providing the related general and 
administrative support for these increased research efforts, including 
increased business development and marketing expenses.

     The Company purchased property and equipment of approximately $16.1 
million during the six months ended June 30, 1998, compared to $3.9 million 
for the corresponding period in 1997. The increase is primarily due to the 
build-out of the Company's manufacturing facility and corporate headquarters 
in San Carlos, California.  This facility will support the Company's late 
stage clinical manufacturing and large-scale commercialization requirements.

     The Company expects its cash requirements to continue to increase at an 
accelerated rate due to expected increases in costs associated with further 
research and development of its technologies, resulting in larger numbers of 
projects, development of drug formulations, process development for the 
manufacture and filling of powders and devices, marketing and general and 
administrative costs. These expenses include, but are not limited to, 
increases in 

                                                                Page 8 of 20


personnel and personnel related costs, purchases of capital equipment, 
investments in technologies, inhalation device prototype construction and 
facilities expansion, including the completion of its late stage clinical and 
commercial manufacturing facility. 

     The Company believes that its cash, cash equivalents and short-term 
investments as of June 30, 1998, together with interest income and possible 
additional equipment financing, will be sufficient to meet its operating 
expense and capital expenditure requirements at least through 1999.  However, 
the Company's capital needs will depend on many factors, including continued 
scientific progress in its research and development arrangements, progress 
with pre-clinical and clinical trials, the time and costs involved in 
obtaining regulatory approvals, the costs of developing and the rate of 
scale-up of the Company's powder processing and packaging technologies, the 
timing and cost of its late-stage clinical and early commercial production 
facility, the costs involved in preparing, filing, prosecuting, maintaining 
and enforcing patent claims, the need to acquire licenses to new technologies 
and the status of competitive products.  To satisfy its long-term needs, the 
Company intends to seek additional funding, as necessary, from corporate 
partners and from the sale of securities.  There can be no assurance that 
additional funds, if and when required, will be available to the Company on 
favorable terms, if at all.

YEAR 2000 COMPLIANCE

     The Company is aware of the issues associated with the programming code 
in existing computer systems as the millennium (year 2000) approaches.  The 
"year 2000" problem is pervasive and complex as virtually every computer 
operation will be affected in some way by the rollover of the two digit year 
value to 00. The issue is whether computer systems will properly recognize 
date sensitive information when the year changes to 2000.  Systems that do 
not properly recognize such information could generate erroneous data or 
cause a system to fail.

     The Company is utilizing both internal and external resources to conduct 
a comprehensive review of its computer systems to identify the systems that 
could be affected by the "year 2000" issue and is developing an 
implementation plan to resolve the issue by the end of 1999.  The Company 
presently believes that, with modifications to existing software and 
converting to new software, the "year 2000" problem will not pose significant 
operational problems for the Company's computer systems as so modified and 
converted.  However, if such modifications and conversions are not completed 
timely, the "year 2000" problem may have a material adverse impact on the 
operations of the Company.

RISK FACTORS 

EARLY STAGE COMPANY.  Inhale is in an early stage of development. There can 
be no assurance that the Company's pulmonary delivery technology will prove 
to be technically feasible or commercially applicable to a range of 
macromolecules and small molecule drugs. Only six of the Company's fourteen 
pulmonary delivery formulations, insulin, interleukin-1 receptor, salmon 
calcitonin, an osteoporosis drug and two small molecules have been subject to 
any human clinical testing. Although many of the underlying drug compounds 
with which the Company is working have been tested in humans by others using 
alternative delivery routes, Inhale's potential products will require 
extensive research, development, pre-clinical and clinical testing, and may 
involve lengthy regulatory review. There can be no assurance that any of the 
Company's potential products will prove to be safe and effective in clinical 
trials, meet applicable regulatory standards, be capable of being produced in 
commercial quantities at acceptable cost or be marketed successfully. Any 
failure of the Company to achieve technical feasibility, demonstrate safety, 
achieve clinical efficacy, obtain regulatory approval or, together with 
partners, successfully market products, would have a material adverse effect 
on the Company. 

 UNCERTAINTIES RELATED TO TECHNOLOGY AND PRODUCT DEVELOPMENT.  The success of 
Inhale's pulmonary drug delivery system for any drugs will depend upon the 
Company achieving sufficient system efficiency (measured by the percentage of 
bulk drug entering the manufacturing process that eventually is absorbed into 
the bloodstream relative to injection for systemic indications, or the amount 
of drug delivered to the lung tissue for local lung indications), formulation 
stability, safety and dosage reproducibility. 

     The initial screening determinant for the feasibility of pulmonary 
delivery of any systemic drug is pulmonary bioavailability, which measures 
the percentage of the drug absorbed into the bloodstream when delivered 
directly to the lungs. In addition, a certain percentage of each drug dose is 
lost at various stages of the manufacturing and pulmonary delivery process in 
drug formulation, dry powder processing, packaging, and in moving the drug 
from a delivery device 

                                                                Page 9 of 20


into the lungs. Excessive drug loss at any one stage or cumulatively in the 
manufacturing and delivery process could render a drug commercially 
unfeasible for pulmonary delivery. 

     Formulation stability (the physical and chemical stability of the 
formulated drug over time and under various storage conditions) and safety 
will vary with each drug and the type and amount of excipients that are used 
in the formulation. Reproducible dosing (the ability to deliver a consistent 
and predictable amount of drug into the bloodstream over time both for a 
single patient and across patient groups) requires the development of an 
inhalation device that consistently delivers predictable amounts of dry 
powder formulations to the deep lung, accurate unit dose packaging of dry 
powder formulations and moisture resistant packaging. There can be no 
assurance that the Company will be able to develop successfully such an 
inhalation device or overcome such other obstacles to reproducible dosing. 

     The Company's integrated approach to systems development relies upon 
several different but related technologies. Development of powder 
formulations, processing and packaging technology and the delivery device, 
establishing collaborations with partners, laboratory and clinical testing, 
and manufacturing scale-up must proceed contemporaneously so as not to delay 
any aspect of systems development. Any delay in one component of product or 
business development could cause consequential delays in the Company's 
ability to develop, obtain approval of or market therapeutic products using 
its system. Further refinement of the Company's device prototype, further 
scale-up of the powder processing system and automated packaging system will 
need to be accomplished before initiation of late stage clinical trials. 

     There can be no assurance that Inhale will be able to demonstrate 
pulmonary bioavailability for the drug candidates it has identified or may 
identify, will be able to achieve commercial viability of its pulmonary 
delivery system or will achieve the total system efficiency needed to be 
competitive with alternative routes of delivery. Further, there can be no 
assurance that the Company's pulmonary delivery system will prove to be safe 
or provide reproducible dosages of stable formulations sufficient to achieve 
clinical efficacy, regulatory approval or market acceptance. In addition, 
there can be no assurance that Inhale will advance the numerous aspects of 
product and business development such that delays in overall product 
development do not occur. The failure to demonstrate pulmonary 
bioavailability, achieve total system efficiency, provide safe, reproducible 
dosages of stable formulations or advance on a timely basis the numerous 
aspects of product and business development would have a material adverse 
effect on the Company. 

UNCERTAINTIES RELATED TO CLINICAL TRIALS.  The Company has limited experience 
in conducting clinical trials and intends to rely primarily on the 
pharmaceutical companies with which it collaborates, including Pfizer Inc. 
and Eli Lilly & Company.  The Company is responsible for managing the 
clinical trials in its collaboration with Baxter Healthcare Corporation 
("Baxter"). Before seeking regulatory approvals for the commercial sale of 
products under development, the Company must demonstrate through pre-clinical 
studies and clinical trials that such products are safe and effective for use 
in the target indications. The results from pre-clinical studies and early 
clinical trials may not be indicative of results that will be obtained in 
large-scale testing, and there can be no assurance that the Company's 
clinical trials will demonstrate sufficient safety and efficacy to obtain the 
requisite regulatory approvals or will result in marketable products. 
Clinical trials are also often conducted with patients having advanced stages 
of disease. During the course of treatment, these patients can die or suffer 
other adverse medical effects for reasons that may not be related to the 
pharmaceutical agent being tested but which can nevertheless affect clinical 
trial results. A number of companies in the pharmaceutical industry have 
suffered significant setbacks in advanced clinical trials, even after 
promising results in earlier trials. Clinical trials for products being 
developed by the Company and its partners may be delayed by many factors, 
including enrolling a sufficient number of patients fitting the appropriate 
trial profile. If any of the Company's products under development are not 
shown to be safe and effective in clinical trials, the resulting delays in 
developing other compounds and conducting related pre-clinical testing and 
clinical trials, as well as the need for additional financing, would have a 
material adverse effect on the Company. 

HISTORY OF OPERATING LOSSES; UNCERTAINTY OF FUTURE PROFITABILITY.  The 
Company has not been profitable since inception and, through June 30, 1998, 
has incurred a cumulative deficit of approximately $44.7 million. The Company 
expects to continue to incur substantial and increasing losses over at least 
the next several years as the Company's research and development efforts, 
preclinical and clinical testing activities and manufacturing scale-up 
efforts expand and as the Company plans and builds its late stage clinical 
and early commercial production facility. All of the Company's potential 
products are in research or in the early stages of development, and no 
revenues have been generated from approved product sales. The Company's 
revenues to date have consisted primarily of payments under short-term 
research and feasibility agreements and development contracts. To achieve and 
sustain profitable operations, the Company, alone or with others, must 
successfully develop, obtain regulatory approval for, manufacture, introduce, 

                                                               Page 10 of 20


market and sell products utilizing its pulmonary drug delivery system. There 
can be no assurance that the Company can generate sufficient product or 
contract research revenue to become profitable or to sustain profitability. 

DEPENDENCE UPON COLLABORATIVE PARTNERS.  The Company currently does not 
possess the resources necessary to develop, obtain regulatory approvals, or 
commercialize any of its potential therapeutic products. The Company's 
ability to apply its pulmonary delivery system to a broad range of drugs will 
depend upon its ability to establish and maintain collaborative arrangements 
since many of the drugs currently approved for sale or in clinical testing 
are covered by third-party patents. The Company has entered into 
collaborative arrangements with certain of its partners to fund clinical 
trials, assist in obtaining regulatory approvals, supply drugs for 
formulation and market and distribute products. While Inhale has also entered 
into agreements with partners to test the feasibility of its pulmonary 
delivery system with certain of their proprietary molecules, there can be no 
assurance that the Company will be able to enter into additional 
collaborations or that its feasibility agreements will lead to 
collaborations. There also can be no assurance that the Company will be able 
to maintain any such collaborative arrangements or feasibility agreements or 
that any such collaborative arrangements or feasibility agreements will be 
successful. The failure of the Company to enter into or maintain such 
collaborative arrangements and feasibility agreements would have a material 
adverse effect on the Company. Moreover, the inability of the Company to 
enter into a collaborative arrangement with the owner of any patented drug 
may preclude the Company from working with such drug. Beginning in October 
1997, Inhale announced its plan to renegotiate with Baxter certain terms of 
their collaboration agreement to address concerns raised by both parties 
about the overall scope and cost of the collaborative arrangement. In April 
1998, the renegotiation of the collaborative agreement with Baxter was 
finalized. Under the revised terms, Inhale and Baxter will focus on the 
product which entered Phase I testing in November 1997 and continue to pursue 
its commercialization. 

     The Company's existing partners have rights to pursue parallel 
development of other drug delivery systems which may compete with the 
Company's pulmonary drug delivery system and to terminate their agreements 
with the Company at any time without significant penalty. The Company 
anticipates that any future partners would have similar rights. Although the 
Company intends generally to formulate and manufacture powders for partners 
and to supply inhalation devices for such powders, certain partners may 
choose to formulate or manufacture their own powders, or to develop or supply 
their own device, thereby limiting one or more potential sources of revenue 
for Inhale. In addition, the Company anticipates that it may be precluded 
from entering into new arrangements with companies whose products compete 
with those of its existing partners. The Company also has limited or no 
control over the resources that any partner may devote to the Company's 
products, over partners' development efforts, including the design and 
conduct of clinical trials, and over the pricing of any such products. The 
pharmaceutical and biotechnology industries are consolidating, and 
acquisitions by, or of, the Company's existing or potential collaborative 
partners may affect the initiation or continuation of any such 
collaborations. There can be no assurances that any of the Company's present 
or future collaborative partners will perform their obligations as expected, 
will devote sufficient resources to the development, clinical testing or 
marketing of the Company's potential products or will not terminate their 
agreements with the Company prematurely or renegotiate such agreements. Any 
parallel development by a partner of alternate drug delivery systems, 
development by a partner rather than by Inhale of components of the delivery 
system, preclusion from entering into competitive arrangements, failure to 
obtain timely regulatory approvals, premature termination of an agreement, 
renegotiation of an agreement, or failure by a partner to devote sufficient 
resources to the development and commercialization of the Company's products 
would have a material adverse effect on the Company. 

LIMITED MANUFACTURING EXPERIENCE; RISK OF SCALE-UP.  To achieve the levels of 
production of Inhale's dry powder drug formulations necessary to support late 
stage human clinical trials and for early commercialization of any of such 
products, the Company will need to scale-up its current powder processing 
facilities and automated filling, build a late stage clinical and early 
commercial production facility, and comply with the good manufacturing 
practice ("GMP") standards prescribed by the United States Food and Drug 
Administration ("FDA") and other standards prescribed by various federal, 
state and local regulatory agencies in the United States and any other 
country of use. 

     The Company has no experience manufacturing products for large scale 
clinical testing or commercial purposes. To date, the Company has performed 
powder processing on the small scale needed for early stage trials and for 
testing formulations of certain other potential therapeutic products and 
scaled-up powder processing for larger clinical trials. There can be no 
assurance that manufacturing and control problems will not arise as the 
Company attempts to further scale-up its powder processing facilities or that 
such scale-up can be achieved in a timely manner or at a commercially 
reasonable cost. Any failure to surmount such problems could delay or prevent 
late stage clinical testing and commercialization of the Company's products 
and would have a material adverse effect on the Company. To date, the Company 
has relied on a particular method of powder processing. There can be no 
assurance that this 

                                                               Page 11 of 20


technology will be applicable to all drugs or that the drug losses in powder 
processing will not be too high for commercial viability for certain drugs.  
In the event that the Company decides to pursue alternative powder processing 
methods for some or all of its drugs, there can be no assurance that these 
methods will prove commercially practical for aerosol drugs or that the 
Company will have or be able to acquire rights to use such alternative 
methods. 

     Fine particle powders and small quantity packaging (such as those to be 
used in the Company's delivery system) require special handling. The Company 
has designed and qualified small scale automated filling equipment for small 
quantity packaging of fine powders. The Company faces significant technical 
challenges scaling-up an automated filling system that can accurately and 
economically handle the small dose and particle sizes of its powders in 
commercial quantities. There can be no assurances that the Company will be 
able to scale-up its automated filling equipment in a timely manner or at 
commercially reasonable costs. Any failure or delay in such scale-up would 
delay product development or bar commercialization of the Company's products 
and would have a material adverse effect on the Company. 

     The Company also faces technical challenges in further developing its 
inhalation device to achieve the efficiency necessary to deliver a broad 
range of drugs, to produce such a device in quantities sufficient for later 
stage clinical trials and early commercialization, and to adapt the device as 
may be required for different powder formulations. There can be no assurance 
that Inhale will successfully achieve such efficiencies, will be able to 
produce such quantities or will be able to adapt the device as required. The 
failure of the Company to overcome any such challenges would have a material 
adverse effect on the Company. For late stage clinical trials and initial 
commercial production, the Company intends to use one or more contract 
manufacturers to produce its device. There can be no assurance that Inhale 
will be able to enter into or maintain such arrangements. The failure of the 
Company to enter into and maintain such arrangements would have a material 
adverse effect on the Company. 

UNCERTAINTY OF MARKET ACCEPTANCE.  The commercial success of the Company's 
pulmonary drug delivery system will depend upon market acceptance by health 
care providers, payors and patients. The Company's products under development 
use a new method of drug delivery, and there can be no assurance that any of 
the Company's products under development will ever achieve market acceptance. 
Market acceptance will depend on many factors, including the safety and 
efficacy results of the Company's clinical trials, favorable regulatory 
approval and product labeling, the frequency of administration, the 
availability of third-party reimbursement, the availability of alternative 
technologies and the price of the Company's products relative to alternative 
technologies. There can be no assurance that health care providers, patients 
or third-party payors will accept the Company's pulmonary drug delivery 
system and the failure to do so would have a material adverse effect on the 
Company. 

FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING.  The Company's 
operations to date have consumed substantial and increasing amounts of cash. 
The negative cash flow from operations is expected to continue and to 
accelerate in the foreseeable future. The development of the Company's 
technology and proposed products will require a commitment of substantial 
funds to conduct costly and time-consuming research, preclinical and clinical 
testing, establish an early commercial production facility and bring any such 
products to market. The Company's future capital requirements will depend on 
many factors, including continued progress in the research and development of 
the Company's technology and drug delivery system, the ability of the Company 
to establish and maintain collaborative arrangements with others and the 
terms thereof, payments received from partners under research and development 
agreements, progress with preclinical and clinical trials, the time and costs 
involved in obtaining regulatory approvals, the cost of development and the 
rate of scale-up of the Company's powder processing and packaging 
technologies, the timing and costs of its late stage clinical and early 
commercial production facility, the cost involved in preparing, filing, 
prosecuting, maintaining and enforcing patent claims, the need to acquire 
licenses to new technology and the status of competitive products. 

     The Company expects that its existing capital resources, contract 
research revenues from collaborations and the net proceeds from the November 
1997 public offering and the interest thereon, will enable the Company to 
maintain its current and planned operations at least through 1999. 
Thereafter, the Company may need to raise substantial additional capital to 
fund its operations. The Company intends to seek such additional funding 
through collaborative or partnering arrangements, the extension of existing 
arrangements, or through public or private equity or debt financings. There 
can be no assurance that additional financing will be available on acceptable 
terms or at all. If additional funds are raised by issuing equity securities, 
further dilution to shareholders may result. If adequate funds are not 
available, the Company may be required to delay, reduce the scope of, or 
eliminate one or more of its research or development programs or obtain funds 
through arrangements with collaborative partners or others that may require 
the Company to 

                                                               Page 12 of 20


relinquish rights to certain of its technologies, product candidates or 
products that the Company would otherwise seek to develop or commercialize. 

DEPENDENCE UPON PROPRIETARY TECHNOLOGY; UNCERTAINTY OF OBTAINING LICENSES OR 
DEVELOPING TECHNOLOGY.  The Company's success will depend in part upon 
protecting its proprietary technology from infringement, misappropriation, 
duplication and discovery. The Company intends to rely principally on a 
combination of patent law, trade secrets and contract law to protect its 
proprietary technology in the United States and abroad. Inhale has filed 
patent applications covering certain aspects of its device, powder processing 
technology, and powder formulations and pulmonary route of delivery for 
certain molecules, and plans to file additional patent applications.  
Currently the Company has been issued nine patents which cover certain 
aspects of its proprietary technology and the Company has a number of patent 
applications pending..  There can be no assurance that any of the patents 
applied for by the Company will issue, or that any patents that issue will be 
valid and enforceable. Even if such patents are enforceable, the Company 
anticipates that any attempt to enforce its patents could be time consuming 
and costly. 

     The patent positions of pharmaceutical, biotechnology and drug delivery 
companies, including Inhale, are uncertain and involve complex legal and 
factual issues. Additionally, the coverage claimed in a patent application 
can be significantly reduced before the patent is issued. As a consequence, 
the Company does not know whether any of its patent applications will result 
in the issuance of patents or, if any patents issue, whether they will 
provide significant proprietary protection or will be circumvented or 
invalidated. Since patent applications in the United States are maintained in 
secrecy until patents issue, and since publication of discoveries in the 
scientific or patent literature often lag behind actual discoveries, the 
Company cannot be certain that it was the first inventor of inventions 
covered by its pending patent applications or that it was the first to file 
patent applications for such inventions. Moreover, the Company may have to 
participate in interference proceedings declared by the PTO to determine 
priority of invention, which could result in substantial cost to the Company, 
even if the eventual outcome is favorable to the Company. An adverse outcome 
could subject the Company to significant liabilities to third parties, 
require disputed rights to be licensed from or to third parties or require 
the Company to cease using the technology in dispute. 

     The Company is aware of numerous pending and issued U.S. and foreign 
patent rights and other proprietary rights owned by third parties that relate 
to aerosol devices and delivery, pharmaceutical formulations, dry powder 
processing technology and the pulmonary route of delivery for certain 
macromolecules. The Company cannot predict with any certainty which, if any, 
patents and patent applications will be considered relevant to the Company's 
technology by authorities in the various jurisdictions where such rights 
exist, nor can the Company predict with certainty which, if any, of these 
rights will or may be asserted against it by such third parties. The Company 
is aware of an alternate dry powder processing technology which Inhale is not 
using for its current products under development but may desire to use for 
certain products in the future. The ownership of this powder processing 
technology is unclear and the Company is aware that multiple parties, 
including Inhale, claim patent, trade secret and other rights in the 
technology. If the Company determines that this alternate powder processing 
technology is relevant to the development of future products and further 
determines that a license to this alternate powder processing technology is 
needed, there can be no assurance that the Company can obtain a license from 
the relevant party or parties on commercially reasonable terms, if at all. 
The Company is also aware of an issued U.S. patent which covers a broad range 
of macromolecule drugs in dry formulations. The Company is evaluating the 
validity of this patent, its relevance to the Company's products and whether 
the license proposed by the patent owner is of interest to the Company. There 
can be no assurance that the Company can obtain any license to any technology 
that the Company determines it needs, on reasonable terms, if at all, or that 
Inhale could develop or otherwise obtain alternate technology. The failure of 
the Company to obtain licenses if needed would have a material adverse effect 
on the Company. 

     In June 1997, the Company acquired the intellectual property portfolio 
of the BioPreservation Division of Pafra Limited of Basildon, England 
("Pafra"). This portfolio includes issued U.S. and foreign Letters Patent and 
pending applications relating to the stabilization of macromolecule drugs in 
dry formulations. A granted European patent included in this portfolio is 
currently the subject of an opposition proceeding before the European Patent 
Office and the Company is continuing the defense of this patent, the 
opposition to which was initiated prior to the acquisition. There can be no 
assurance that the Company will be successful in the defense of this 
opposition proceeding. In addition, there can be no assurance that any of the 
Pafra patent applications will issue, or that any Pafra patents will be valid 
and enforceable. The loss of the opposition proceeding or the inability to 
obtain or defend the Pafra patents could have a material adverse effect on 
the Company. 

                                                               Page 13 of 20


     Third parties from time to time have asserted and may assert that the 
Company is employing technology that they believe is based on issued patents, 
trade secrets or know-how of others. In addition, future patents may issue to 
third parties which the Company's technology may infringe. The Company could 
incur substantial costs in defending itself and its partners against any such 
claims. Furthermore, parties making such claims may be able to obtain 
injunctive or other equitable relief which could effectively block the 
Company's ability to further develop or commercialize some or all of its 
products in the United States and abroad, and could result in the award of 
substantial damages. In the event of a claim of infringement, the Company and 
its partners may be required to obtain one or more licenses from third 
parties. There can be no assurances that the Company or its partners will be 
able to obtain such licenses at a reasonable cost, if at all. Defense of any 
lawsuit or failure to obtain any such license could have a material adverse 
effect on the Company. 

     The Company's ability to develop and commercialize its technology will 
be affected by the Company's or its partners' access to the drugs which are 
to be formulated. Many drugs, including powder formulations of certain drugs 
which are presently under development by the Company, are subject to issued 
and pending United States and foreign patent rights which may be owned by 
competing entities. There are issued patents and pending patent applications 
relating to the pulmonary delivery of macromolecule drugs, including several 
for which the Company is developing pulmonary delivery formulations. 
Specifically, patents have been granted in the United States and Europe 
directed to aerosol formulations for the treatment of the lung containing 
alpha-1 antitrypsin (U.S.) and serine protease inhibitors, including alpha-1 
antitrypsin (Europe). The Company's development partner for alpha-1 
antitrypsin, Centeon L.L.C (a joint venture of Hoechst AG and Rhone-Poulenc 
Rorer, Inc.) ("Centeon"), is negotiating with multiple partners to secure 
rights under these patents. The failure by Centeon to secure rights under 
these patents could result in the termination of this program by Centeon. The 
resulting patent situation is highly complex, and the ability of any one 
company to commercialize a particular biopharmaceutical drug is highly 
unpredictable. The Company intends generally to rely on the ability of its 
partners to provide access to the drugs which are to be formulated for 
pulmonary delivery. There can be no assurance that the Company's partners 
will be able to provide access to drug candidates for formulation for 
pulmonary delivery or that, if such access is provided, the Company or its 
partners will not be accused of, or determined to be, infringing a third 
party's rights and will not be prohibited from working with the drug or be 
found liable for damages that may not be subject to indemnification. Any such 
restriction on access or liability for damages would have a material adverse 
effect on the Company. 

     The Company also will rely on trade secrets and contract law to protect 
certain of its proprietary technology. There can be no assurance that any 
such contract will not be breached, or that if breached, the Company will 
have adequate remedies. Furthermore, there can be no assurance that any of 
the Company's trade secrets will not become known or independently discovered 
by third parties. 

     In 1995 the PTO adopted changes to the United States patent law that 
changed the term of issued patents, subject to certain transition periods, to 
20 years from the date of filing rather than 17 years from date of issuance. 
Beginning in June 1995, the patent term became 20 years from the earliest 
effective filing date of the underlying patent application. Such change may 
reduce the effective term of protection for patents that are pending for more 
than three years in the PTO. In addition, as of January 1996, all inventors 
who work outside of the United States are able to establish a date of 
invention on the same basis as those working in the United States. Such 
change could adversely affect the ability of the Company to prevail in a 
priority of invention dispute with a third party located or doing work 
outside of the United States. While the Company cannot predict the effect 
that such changes will have on its business, such changes could have a 
material adverse effect on the Company's ability to protect its proprietary 
information and sustain the commercial viability of its products. 
Furthermore, the possibility of extensive delays in such process, could 
effectively further reduce the term during which a marketed product could be 
protected by patents. 

DEPENDENCE UPON AND NEED TO ATTRACT KEY PERSONNEL.  The Company is highly 
dependent upon the principal members of its scientific and management staff. 
The Company does not have employment contracts with its key employees, nor 
does the Company have key man insurance policies on them. The Company also 
relies on consultants and advisors to assist the Company in formulating 
research and development strategy. To pursue its product development and 
commercialization plans, the Company will be required to hire additional 
qualified scientific personnel to perform research and development, as well 
as personnel with expertise in clinical testing, government regulation and 
manufacturing. Expansion in product development and manufacturing also is 
expected to require the addition of management personnel and the development 
of additional expertise by existing management personnel. Retaining and 
attracting qualified personnel, consultants and advisors will be critical to 
the Company's success. The Company faces competition for qualified 
individuals from numerous pharmaceutical, biotechnology and drug delivery 
companies, 

                                                               Page 14 of 20


universities and other research institutions. There can be no assurance that 
the Company will be able to retain its current key employees or attract and 
retain qualified additional personnel and management when needed and its 
failure to do so would have a material adverse effect on the Company's 
ability to develop and commercialize products. 

GOVERNMENT REGULATION; UNCERTAINTY OF OBTAINING REGULATORY APPROVAL.  The 
production and marketing of the Company's products and its ongoing research 
and development activities are subject to regulation by numerous governmental 
authorities in the United States and other countries. Prior to marketing a 
new dosage form of any drug, including one developed for use with the 
Company's pulmonary drug delivery system, whether or not such drug was 
already approved for marketing in another dosage form, the product must 
undergo rigorous preclinical and clinical testing and an extensive review 
process mandated by the FDA and equivalent foreign authorities. These 
processes generally take a number of years and require the expenditure of 
substantial resources. None of the Company's proposed products has been 
submitted to the FDA for marketing approval. The Company has no experience 
obtaining such regulatory approval, does not have the expertise or other 
resources to do so and intends to rely on its partners to fund clinical 
testing and to obtain product approvals. 

     The time required for completing such testing and obtaining such 
approvals is uncertain. Further refinement of the device prototype, further 
scale-up of the powder processing system and automated powder filling and 
packaging system will need to be accomplished before initiation of later 
stage clinical trials. Any delay in any of these components of product 
development may delay testing. In addition, delays or rejections may be 
encountered based upon changes in FDA policy, including FDA policy relating 
to GMP compliance, during the period of product development. Similar delays 
may also be encountered in other countries. If regulatory approval of a 
product is granted, such approval may entail limitations on the indicated 
uses for which the product may be marketed, and the marketed product, its 
manufacturer, and its manufacturing facilities remain subject to continual 
review and periodic inspections. Later discovery of previously unknown 
problems with a product, manufacturer or facility may result in restrictions 
on such product or manufacturer, including withdrawal of the product from the 
market. There can be no assurance that regulatory approval will be obtained 
for any products developed by the Company on a timely basis, or at all. The 
failure to obtain timely regulatory approval of its products, any product 
marketing limitations or a product withdrawal would have a material adverse 
effect on the Company. 

UNCERTAINTY RELATED TO THE HEALTH CARE INDUSTRY AND THIRD-PARTY 
REIMBURSEMENT. Political, economic and regulatory influences are subjecting 
the health care industry in the United States to fundamental change. Recent 
initiatives to reduce the federal deficit and to reform health care delivery 
are increasing cost-containment efforts. The Company anticipates that 
Congress, state legislatures and the private sector will continue to review 
and assess alternative benefits, controls on health care spending through 
limitations on the growth of private health insurance premiums and Medicare 
and Medicaid spending, the creation of large insurance purchasing groups, 
price controls on pharmaceuticals and other fundamental changes to the health 
care delivery system. Any such proposed or actual changes could cause the 
Company or its collaborative partners to limit or eliminate spending on 
development projects. Legislative debate is expected to continue in the 
future, and market forces are expected to demand reduced costs. Inhale cannot 
predict what effect the adoption of any federal or state health care reform 
measures or future private sector reforms may have on its business. 

     In both domestic and foreign markets, sales of the Company's products 
under development will depend in part upon the availability of reimbursement 
from third-party payors, such as government health administration 
authorities, managed care providers, private health insurers and other 
organizations. In addition, other third-party payors are increasingly 
challenging the price and cost effectiveness of medical products and 
services. Significant uncertainty exists as to the reimbursement status of 
newly approved health care products. There can be no assurance that the 
Company's proposed products will be considered cost effective or that 
adequate third-party reimbursement will be available to enable Inhale to 
maintain price levels sufficient to realize an appropriate return on its 
investment in product development. Legislation and regulations affecting the 
pricing of pharmaceuticals may change before the Company's proposed products 
are approved for marketing. Adoption of such legislation could further limit 
reimbursement for medical products. If adequate coverage and reimbursement 
levels are not provided by the government and third-party payors for the 
Company's potential products, the market acceptance of these products would 
be adversely affected, which would have a material adverse effect on the 
Company. 

HIGHLY COMPETITIVE INDUSTRY; RISK OF TECHNOLOGICAL OBSOLESCENCE.  The 
biotechnology and pharmaceutical industries are highly competitive and 
rapidly evolving and significant developments are expected to continue at a 
rapid pace. The Company's success depends upon maintaining a competitive 
position in the development of products and technologies 

                                                               Page 15 of 20


for pulmonary delivery of pharmaceutical drugs. If a competing company were 
to develop or acquire rights to a better dry powder pulmonary delivery device 
or fine powder processing technology, a better system for efficiently and 
reproducibly delivering drugs to the deep lung, a non-invasive drug delivery 
system which is more attractive for the delivery of drugs than pulmonary 
delivery, or an invasive delivery system which overcomes some of the 
drawbacks of current invasive systems for chronic or subchronic indications 
(such as a sustained release system), the Company's business could be 
materially adversely affected. 

     The Company is in competition with pharmaceutical, biotechnology and 
drug delivery companies, hospitals, research organizations, individual 
scientists and nonprofit organizations engaged in the development of 
alternative drug delivery systems or new drug research and testing, as well 
as with entities producing and developing injectable drugs. The Company is 
aware of a number of companies currently seeking to develop new products and 
non-invasive alternatives to injectable drug delivery, including oral 
delivery systems, intranasal delivery systems, transdermal systems and 
colonic absorption systems. Several of these companies may have developed or 
be developing dry powder devices that could be used for pulmonary delivery. 
The Company is also aware of other companies currently engaged in the 
development and commercialization of pulmonary drug delivery systems and 
enhanced injectable drug delivery systems. Many of these companies and 
entities have greater research and development capabilities, experience, 
manufacturing, marketing, financial and managerial resources than the Company 
and represent significant competition for the Company. Acquisitions of 
competing drug delivery companies by large pharmaceutical companies could 
enhance competitors' financial, marketing and other resources. Accordingly, 
the Company's competitors may succeed in developing competing technologies, 
obtaining FDA approval for products or gain market acceptance more rapidly 
than the Company. There can be no assurance that developments by others will 
not render the Company's products or technologies uncompetitive or obsolete. 

PRODUCT LIABILITY; AVAILABILITY OF INSURANCE.  The design, development and 
manufacture of the Company's products involve an inherent risk of product 
liability claims and associated adverse publicity. Although the Company 
currently maintains general liability insurance, there can be no assurance 
that the coverage limits of the Company's insurance policies will be 
adequate. The Company obtained clinical trial product liability insurance of 
$3.0 million per event for certain clinical trials and intends to obtain 
insurance for future clinical trials of insulin and other products under 
development. There can be no assurance, however, that the Company will be 
able to obtain or maintain insurance for any future clinical trials. Such 
insurance is expensive, difficult to obtain and may not be available in the 
future on acceptable terms, or at all. A successful claim brought against the 
Company in excess of the Company's insurance coverage would have a material 
adverse effect upon the Company and its financial condition. 

HAZARDOUS MATERIALS.  The Company's research and development involves the 
controlled use of hazardous materials, chemicals and various radioactive 
compounds. Although the Company believes that its safety procedures for 
handling and disposing of such materials comply with the standards prescribed 
by state and federal regulations, the risk of accidental contamination or 
injury from these materials cannot be completely eliminated. In the event of 
such an accident, the Company could be held liable for any damages that 
result and any such liability could exceed the resources of the Company. The 
Company may incur substantial costs to comply with environmental regulations. 

ANTI-TAKEOVER PROVISIONS.  Certain provisions of the Company's Certificate of 
Incorporation and the Delaware General Corporation Law could discourage a 
third party from attempting to acquire, or make it more difficult for a third 
party to acquire, control of the Company without approval of the Company's 
Board of Directors. Such provisions could also limit the price that certain 
investors might be willing to pay in the future for shares of Common Stock. 
Certain of the provisions allow the Board of Directors to authorize the 
issuance of Preferred Stock with rights superior to those of the Common 
Stock. 

POTENTIAL VOLATILITY OF STOCK PRICE.  The market prices for securities of 
early stage biotechnology companies have historically been highly volatile 
and the market from time to time experienced significant price and volume 
fluctuations that are unrelated to the operating performance of particular 
companies. Factors such as fluctuations in the Company's operating results, 
announcements of technological innovations or new therapeutic products or the 
announcement or termination of collaborative relationships by the Company or 
its competitors, governmental regulation, clinical trial results, 
developments in patent or other proprietary rights, public concern as to the 
safety of drug formulations developed by the Company or others and general 
market conditions may have a significant effect on the market price of the 
Common Stock. The Company's securities are subject to a high degree of risk 
and volatility. In the past, following periods of volatility in the market 
price of a company's securities, class action securities litigation has often 
been instituted against such a company. Any such litigation instigated 
against the Company could result in substantial costs 

                                                               Page 16 of 20


and a diversion of management's attention and resources, which could have a 
material adverse effect on the Company's business, financial condition and 
operating results.
