ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

RESULTS OF OPERATIONS
Three and Nine Months Ended September 30, 1997 and 1998

Total revenues for the three and nine months ended September 30, 1998, were
$702,667 and $2,395,228, respectively. These figures reflect an increase in the
quarter of $92,839, or 15%, and a decrease of $67,004, or 3% in the nine month
period compared to the same periods in 1997. In each 1998 period, licensing and
development fee income decreased and product sales increased compared to the
same periods in 1997.

Product sales increased by $269,372, or 79% in the quarter and by $644,234, or
53% in the nine months ended September 30, 1998, as compared to the same periods
in 1997. These increases 

                                       6
<PAGE>
 
were driven by an increase in the number of injector units and related
disposables sold in each period. The average selling price of injector units
decreased approximately 7% in the nine months ended September 30, 1998, compared
to the prior year period, as a result of increased unit sales at a lower selling
price in the human growth hormone market. Product sales decreased in the U.S.
insulin market as a consequence of the reduced selling efforts in that market,
which is discussed more fully in the sales and marketing section below.

Licensing and product development fee income decreased by $176,633, or 66% in
the quarter and $711,238, or 57% in the nine months ended September 30, 1998,
compared to the same periods in 1997. These decreases relate primarily to the
completion in December 1997 of a two-year product development funding contract
with Becton Dickinson and Company. The Company expects that licensing and
product development fee income will fluctuate on a quarterly basis, depending on
a variety of factors; including the timing of execution of potential development
and licensing agreements and the timing, nature and size of fee payments to be
made under existing and new agreements. In addition, since the Company does not,
in general, recognize project-based fee income until related development work
has been performed, quarterly results will fluctuate with the timing of the
Company's research and development efforts.

Cost of sales in the three and nine months ended September 30, 1998, were
$501,068 and $1,502,438, respectively. These figures reflect increases of
$237,955, or 90% and $691,316, or 85% from the three and nine month periods of
the prior year, respectively. These increases relate primarily to an increase in
the amount of product sold in each period, along with higher overall
manufacturing overhead expenses. Manufacturing overhead expenses increased as a
result of additional engineering personnel, higher rent and increased
depreciation expense.

Research and development expenses totaled $680,026 and $1,873,682 in the three
and nine months ended September 30, 1998, respectively. These figures reflect
increases of $184,333, or 37% in the quarter and $75,688, or 4% in the nine
months ended September 30, 1998, compared to the same period in 1997. These
increases were attributable to increased compensation and clinical studies
expenses relating to ongoing development projects. Consulting expenses declined
in each period due to a transfer of responsibilities from outside consultants to
internal personnel.

General and administrative expenses totaled $615,355 and $1,726,982 in the three
and nine months ended September 30, 1998, respectively. In comparison to the
prior year, these figures reflect increases of $116,409, or 23% and $342,416, or
25% in the three and nine months ended September 30, 1998, respectively. In the
quarterly period, a majority of the increase is attributable to a one-time
expense relating to the Company's repurchase of certain distribution rights in
the human growth hormone market from one of its distributors. The repurchase of
these rights has allowed the Company to sign a new agreement that is expected to
generate fee income and product sales in the future. The most significant
components of the expense increase in the nine months ended September 30, 1998
include regulatory and quality assurance related items, the repurchase of
marketing rights as discussed above, as well as moderate increases in
compensation, business insurance and depreciation. The regulatory and quality
assurance expense increase relates to both one-time ISO 9000 certification
expenses in 1998, and an increase in on-going quality assurance efforts.

                                       7

Sales and marketing expenses totaled $235,063 and $708,077 in the three and nine
months ended September 30, 1998, respectively. These figures reflect decreases
of $166,322, or 41% and $459,293, or 39% compared to the three and nine months
ended September 30, 1997, respectively. These decreases relate primarily to a
reduction of expenses in the sales and marketing program in the U.S. insulin
market initiated by the Company in October 1997. This reduction in expenses is
consistent with the Company's long term strategy of selling product through
pharmaceutical companies with a focus on higher priced pharmaceuticals.

Net other income (expense), decreased by $55,720 and $138,215 compared to the
prior year in the three and nine month periods ended September 30, 1998,
respectively. These decreases primarily reflect a decrease in interest income
attributable to lower average cash balances.

LIQUIDITY AND CAPITAL RESOURCES

Cash, cash equivalents and marketable securities totaled $7,283,334 on December
31, 1997, compared to $3,938,324 on September 30, 1998. This decrease of
$3,345,010 results primarily from an operating loss of $3,182,486 in addition to
increases in inventory of $225,736, increases in capital equipment of $574,287
related primarily to tooling investment on next generation products, and was
offset in part by a $453,073 reduction in accounts receivable. The reduction in
accounts receivable was primarily due to the collection of certain licensing and
development fee receivables that were outstanding at year end.

The Company's long term capital requirements will depend on numerous factors,
including the status of the Company's collaborative arrangements, the progress
of the Company's research and development programs and the receipt of revenues
from sales of the Company's products. In October, 1998 the Company took certain
actions to reduce its operating expenses. These actions included both voluntary
and involuntary staff reductions. The Company believes that cash on hand,
interest expected to be earned thereon and anticipated revenues, will meet its
needs through the next twelve months. In order to meet its capital needs beyond
this period, the Company may be required to raise additional capital through
public or private debt or equity offerings.

IMPACT OF THE YEAR 2000

The Company is addressing the issue 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. The Company is aware of the computing difficulties
that the millennium issue presents for the Year 2000.

The Company has identified a team to address the information technology (IT)
systems used for internal purposes at the Company and to also address the non-IT
systems. It is anticipated that all reprogramming efforts for internally used IT
systems will be complete by December 31,1998, allowing adequate time for
testing. The non-IT systems generally require third-party assurances as to
compliance with Year 2000. To date, confirmations have been received from
approximately 80% of the Company's vendors indicating that plans are being
developed to address processing of transactions in the Year 2000. There can be
no assurance that the Company will not experience serious unanticipated negative
consequences and/or material costs caused by undetected errors or 

                                       8
<PAGE>
 
defects in the technology used in its internal operating systems, which are
composed predominantly of third party software and hardware technology or by the
inability of vendors to correct their Year 2000 issues. The majority of the
Company's current standard product lines and manufacturing equipment are not
date sensitive and therefore are not affected by the Year 2000 issues.

The Company incurred approximately $5,000 of expense to address the Year 2000
problem during fiscal 1998 to date and will incur approximately $20,000 in total
expense. The Company is in the process of establishing a contingency plan if the
Company's IT and non-IT systems are not Year 2000 compliant. It is anticipated
that the contingency plan will be completed by December 31,1998.

NEW ACCOUNTING PRONOUNCEMENTS

Effective January 1,1998, the Company adopted FASB Statement No. 130 (SFAS No.
130), "Reporting Comprehensive Income". SFAS No. 130 requires that an entity
report a total for comprehensive income or loss in condensed financial
statements of interim periods issued to shareholders. For the three and nine
month periods ended September 30,1998, the comprehensive loss is equal to the
net loss as reported in the Statements of Operations.

Item 1.   Legal Proceedings.

          None.

Item 2.   Changes in Securities (Use of proceeds from public offering)

          The Company's initial Registration Statement on Form S-1, file no.
          333-6661, was declared effective by the Securities and Exchange
          Commission on October 10, 1996. The offering of the Company's Common
          Stock covered by such Registration Statement commenced on October 2,
          1996. Rodman & Renshaw and R.J. Steichen & Company acted as the
          managing underwriters ("the Representatives") for the offering. A
          total of 2,750,000 shares of Common Stock, including 330,000 shares
          subject to the Representatives over-allotment option and 220,000
          shares subject to the warrants issued to the Representatives were
          registered. In addition, warrants to purchase 220,000 shares of Common
          Stock issued to the Representatives were also registered. The
          aggregate offering price of the registered Common Stock and warrants
          was $15,367,220. Of this amount, $12,100,000 representing 2,200,000
          shares of Common Stock and warrants to purchase 220,000 shares of
          Common Stock have been sold. The underwriter's over-allotment option
          has expired and these shares were not sold. The Representative's
          warrant has not yet been exercised and consequently the offering has
          not yet terminated.

          The amount of expenses incurred for the Company's account in
          connection with the issuance and distribution of the securities
          registered are as follows:

          Underwriting discounts and commissions:......  $  907,500

          The net offering proceeds to the Company after deducting expenses were
          $10,629,881. The amount of net offering proceeds to the Company used

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

RESULTS OF OPERATIONS
Three and Nine Months Ended September 30, 1997 and 1998

Total revenues for the three and nine months ended September 30, 1998, were
$702,667 and $2,395,228, respectively. These figures reflect an increase in the
quarter of $92,839, or 15%, and a decrease of $67,004, or 3% in the nine month
period compared to the same periods in 1997. In each 1998 period, licensing and
development fee income decreased and product sales increased compared to the
same periods in 1997.

Product sales increased by $269,372, or 79% in the quarter and by $644,234, or
53% in the nine months ended September 30, 1998, as compared to the same periods
in 1997. These increases 

                                       6
were driven by an increase in the number of injector units and related
disposables sold in each period. The average selling price of injector units
decreased approximately 7% in the nine months ended September 30, 1998, compared
to the prior year period, as a result of increased unit sales at a lower selling
price in the human growth hormone market. Product sales decreased in the U.S.
insulin market as a consequence of the reduced selling efforts in that market,
which is discussed more fully in the sales and marketing section below.

Licensing and product development fee income decreased by $176,633, or 66% in
the quarter and $711,238, or 57% in the nine months ended September 30, 1998,
compared to the same periods in 1997. These decreases relate primarily to the
completion in December 1997 of a two-year product development funding contract
with Becton Dickinson and Company. The Company expects that licensing and
product development fee income will fluctuate on a quarterly basis, depending on
a variety of factors; including the timing of execution of potential development
and licensing agreements and the timing, nature and size of fee payments to be
made under existing and new agreements. In addition, since the Company does not,
in general, recognize project-based fee income until related development work
has been performed, quarterly results will fluctuate with the timing of the
Company's research and development efforts.

Cost of sales in the three and nine months ended September 30, 1998, were
$501,068 and $1,502,438, respectively. These figures reflect increases of
$237,955, or 90% and $691,316, or 85% from the three and nine month periods of
the prior year, respectively. These increases relate primarily to an increase in
the amount of product sold in each period, along with higher overall
manufacturing overhead expenses. Manufacturing overhead expenses increased as a
result of additional engineering personnel, higher rent and increased
depreciation expense.

Research and development expenses totaled $680,026 and $1,873,682 in the three
and nine months ended September 30, 1998, respectively. These figures reflect
increases of $184,333, or 37% in the quarter and $75,688, or 4% in the nine
months ended September 30, 1998, compared to the same period in 1997. These
increases were attributable to increased compensation and clinical studies
expenses relating to ongoing development projects. Consulting expenses declined
in each period due to a transfer of responsibilities from outside consultants to
internal personnel.

General and administrative expenses totaled $615,355 and $1,726,982 in the three
and nine months ended September 30, 1998, respectively. In comparison to the
prior year, these figures reflect increases of $116,409, or 23% and $342,416, or
25% in the three and nine months ended September 30, 1998, respectively. In the
quarterly period, a majority of the increase is attributable to a one-time
expense relating to the Company's repurchase of certain distribution rights in
the human growth hormone market from one of its distributors. The repurchase of
these rights has allowed the Company to sign a new agreement that is expected to
generate fee income and product sales in the future. The most significant
components of the expense increase in the nine months ended September 30, 1998
include regulatory and quality assurance related items, the repurchase of
marketing rights as discussed above, as well as moderate increases in
compensation, business insurance and depreciation. The regulatory and quality
assurance expense increase relates to both one-time ISO 9000 certification
expenses in 1998, and an increase in on-going quality assurance efforts.

                                       7
Sales and marketing expenses totaled $235,063 and $708,077 in the three and nine
months ended September 30, 1998, respectively. These figures reflect decreases
of $166,322, or 41% and $459,293, or 39% compared to the three and nine months
ended September 30, 1997, respectively. These decreases relate primarily to a
reduction of expenses in the sales and marketing program in the U.S. insulin
market initiated by the Company in October 1997. This reduction in expenses is
consistent with the Company's long term strategy of selling product through
pharmaceutical companies with a focus on higher priced pharmaceuticals.

Net other income (expense), decreased by $55,720 and $138,215 compared to the
prior year in the three and nine month periods ended September 30, 1998,
respectively. These decreases primarily reflect a decrease in interest income
attributable to lower average cash balances.

LIQUIDITY AND CAPITAL RESOURCES

Cash, cash equivalents and marketable securities totaled $7,283,334 on December
31, 1997, compared to $3,938,324 on September 30, 1998. This decrease of
$3,345,010 results primarily from an operating loss of $3,182,486 in addition to
increases in inventory of $225,736, increases in capital equipment of $574,287
related primarily to tooling investment on next generation products, and was
offset in part by a $453,073 reduction in accounts receivable. The reduction in
accounts receivable was primarily due to the collection of certain licensing and
development fee receivables that were outstanding at year end.

The Company's long term capital requirements will depend on numerous factors,
including the status of the Company's collaborative arrangements, the progress
of the Company's research and development programs and the receipt of revenues
from sales of the Company's products. In October, 1998 the Company took certain
actions to reduce its operating expenses. These actions included both voluntary
and involuntary staff reductions. The Company believes that cash on hand,
interest expected to be earned thereon and anticipated revenues, will meet its
needs through the next twelve months. In order to meet its capital needs beyond
this period, the Company may be required to raise additional capital through
public or private debt or equity offerings.

IMPACT OF THE YEAR 2000

The Company is addressing the issue 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. The Company is aware of the computing difficulties
that the millennium issue presents for the Year 2000.

The Company has identified a team to address the information technology (IT)
systems used for internal purposes at the Company and to also address the non-IT
systems. It is anticipated that all reprogramming efforts for internally used IT
systems will be complete by December 31,1998, allowing adequate time for
testing. The non-IT systems generally require third-party assurances as to
compliance with Year 2000. To date, confirmations have been received from
approximately 80% of the Company's vendors indicating that plans are being
developed to address processing of transactions in the Year 2000. There can be
no assurance that the Company will not experience serious unanticipated negative
consequences and/or material costs caused by undetected errors or 

                                       8
defects in the technology used in its internal operating systems, which are
composed predominantly of third party software and hardware technology or by the
inability of vendors to correct their Year 2000 issues. The majority of the
Company's current standard product lines and manufacturing equipment are not
date sensitive and therefore are not affected by the Year 2000 issues.

The Company incurred approximately $5,000 of expense to address the Year 2000
problem during fiscal 1998 to date and will incur approximately $20,000 in total
expense. The Company is in the process of establishing a contingency plan if the
Company's IT and non-IT systems are not Year 2000 compliant. It is anticipated
that the contingency plan will be completed by December 31,1998.

NEW ACCOUNTING PRONOUNCEMENTS

Effective January 1,1998, the Company adopted FASB Statement No. 130 (SFAS No.
130), "Reporting Comprehensive Income". SFAS No. 130 requires that an entity
report a total for comprehensive income or loss in condensed financial
statements of interim periods issued to shareholders. For the three and nine
month periods ended September 30,1998, the comprehensive loss is equal to the
net loss as reported in the Statements of Operations.

Item 2.   Changes in Securities (Use of proceeds from public offering)

          The Company's initial Registration Statement on Form S-1, file no.
          333-6661, was declared effective by the Securities and Exchange
          Commission on October 10, 1996. The offering of the Company's Common
          Stock covered by such Registration Statement commenced on October 2,
          1996. Rodman & Renshaw and R.J. Steichen & Company acted as the
          managing underwriters ("the Representatives") for the offering. A
          total of 2,750,000 shares of Common Stock, including 330,000 shares
          subject to the Representatives over-allotment option and 220,000
          shares subject to the warrants issued to the Representatives were
          registered. In addition, warrants to purchase 220,000 shares of Common
          Stock issued to the Representatives were also registered. The
          aggregate offering price of the registered Common Stock and warrants
          was $15,367,220. Of this amount, $12,100,000 representing 2,200,000
          shares of Common Stock and warrants to purchase 220,000 shares of
          Common Stock have been sold. The underwriter's over-allotment option
          has expired and these shares were not sold. The Representative's
          warrant has not yet been exercised and consequently the offering has
          not yet terminated.

          The amount of expenses incurred for the Company's account in
          connection with the issuance and distribution of the securities
          registered are as follows:

          Underwriting discounts and commissions:......  $  907,500
