                              ORPHAN MEDICAL, INC.
                          (A Development Stage Company)

                          NOTES TO FINANCIAL STATEMENTS
                                   (Unaudited)

1. BASIS OF PRESENTATION
Orphan Medical, Inc. (the "Company") is a development stage company that
acquires, develops, and markets products of high medical value intended to
address inadequately treated or uncommon diseases within selected strategic
therapeutic market segments. A drug has high medical value if it offers a major
improvement in the safety or efficacy of patient treatment and has no
substantial equivalent substitute. The Company is currently developing two
potential products and has five products that have been approved for marketing
by the Food and Drug Administration (the "FDA").

The accompanying unaudited financial statements have been prepared in accordance
with generally accepted accounting principles for interim financial information
and with the instructions to Form 10-Q and Article 10 of Regulation S-X.
Accordingly, these financial statements do not include all of the information
and footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal, recurring accruals) considered necessary for fair presentation have
been included. Operating results for the three and six month periods ended June
30, 1998 are not necessarily indicative of the results that may be expected for
the year ended December 31, 1998. For further information, refer to the audited
financial statements and accompanying notes contained in the Company's Annual
Report filed on Form 10-K for the year ended December 31, 1997.

2. USE OF ESTIMATES
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.

3. LOSS PER SHARE
Basic and diluted loss per share are based upon the weighted average number of
shares outstanding during the respective period. Common stock equivalents are
not included because their effect is anti-dilutive.

4. CHRONIMED OBLIGATION
The Company and Chronimed entered into an Agreement dated June 27, 1997, in
which Chronimed agreed to terminate certain agreements that had been in
existence since the spin-off of the Company from Chronimed. Among the terminated
agreements was the Marketing and Distribution Agreement dated July 2, 1994, as
amended, under which Chronimed had the exclusive right to market and distribute
four of Orphan Medical's proposed products and receive royalties with respect to
two of Orphan Medical's products. In consideration for terminating 

<PAGE>


these agreements, the Company agreed to pay Chronimed compensation equal to
$2,500,000, consisting of cash and shares of the Company's Common Stock. The
Company paid $250,000 on June 27, 1997, with the remaining balance of $2,250,000
payable in quarterly installments based on a temporary royalty arrangement equal
to 3 percent of the Company's net sales beginning in the third quarter of 1997
and the issuance on a quarterly basis of Common Stock equal to 1 percent of the
Company's then issued and outstanding Common Stock beginning March 31, 1998.
Through June 30, 1998, the Company has paid Chronimed approximately $81,000 in
royalties and issued 123,056 shares of Common Stock, of which 61,178 shares have
been sold by Chronimed in market transactions for net cash proceeds of $576,183.
At June 30, 1998, the Company's unpaid obligation to Chronimed has an estimated
value of approximately $1,146,666, which is classified as a "Current Liability".

5. COMMITMENTS
The Company has various commitments under agreements with outside consultants,
contract drug development companies, manufacturers, technical service companies,
license and research agreements, and agreements with drug distributors.
Expenditures incurred under these commitments and reported as research and
development expense totaled approximately $1,584,000 and $3,058,000 for the
three and six month periods ended June 30, 1998, respectively. At June 30, 1998,
the Company estimates that it could incur approximately $3,436,000 of additional
expenditures in subsequent periods under existing commitments for those products
remaining in the Company's development portfolio. Commitments for research and
development expenditures will likely fluctuate from quarter to quarter and from
year to year depending on, among other factors, the timing of product
development and the progress of clinical development programs.

6. BORROWINGS
The Company has a commercial revolving line of credit with a bank, which expires
on May 15, 1999. The maximum amount available to the Company under this
arrangement is $500,000, subject to certain limitations. The Company's
indebtedness to the bank may not exceed the lesser of (1) 75 percent of the
Company's trade accounts receivable that have been outstanding for 90 days or
less or (2) $500,000. In addition, the Company must maintain a minimum balance
of at least $250,000 in accounts which the bank controls. Advances are charged a
variable rate of interest equal to the prime rate plus one half of a percent.
Through June 30, 1998, the Company has not borrowed under this arrangement.

7. RECLASSIFICATIONS
Certain prior period balances have been reclassified in order to conform with
the presentation for the three and six months ended June 30, 1998. These
reclassifications have no impact on the net loss or shareholders' equity as
previously reported.

8. SUBSEQUENT EVENT
On July 23, 1998 (the "First Issuance Date"), the Company completed the sale to
UBS Capital II LLC ("UBS Capital") of a private placement of $7.5 million of
Senior Convertible Preferred Stock (the "Preferred Shares"). The private
placement agreement also gives UBS Capital the right to invest up to an
additional $4.5 million within 90 days of the First Issuance Date. The Preferred
Shares are

<PAGE>


convertible, at the option of the holders, into shares of the Company's Common
Stock at a per share price equal to the lesser of $11.78 or 110% of the average
last sale price of the 20 trading days prior to October 21, 1998. The Preferred
Shares have anti-dilution and change of control protection, and bear a dividend
of 7.5% per annum, payable semi annually, which during the first two years may
be paid either in cash or by issuing additional Preferred Shares. In the third
year and thereafter, the dividend may be paid either in cash or by issuing
Common Stock valued at the then current market price. Ten years from the First
Issuance Date (July 23, 2008), the Company must elect to either (1) require the
conversion of all unconverted Preferred Shares into Common Stock upon the
payment by the Company, in cash or by issuing Common Stock, of a $3.0 million
conversion fee, which is subject to adjustment, or (2) redeem for cash the
holder's unconverted Preferred Shares for $1,000 per share plus accrued
dividends. An affiliate of UBS Capital will be paid on closing a four percent
arrangement fee based on amounts invested. UBS Capital is entitled to designate
an individual to serve on the Company's Board of Directors.

of Operations

CAUTIONARY STATEMENT
This Quarterly Report on Form 10-Q contains statements that are not descriptions
of historical facts. The words or phrases "will likely result", "look for", "may
result", "will continue", "is anticipated", "expect", "project", or similar
expressions are intended to identify "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995. Such statements
may be forward-looking statements that are subject to risks and uncertainties.
Actual results could differ materially from those currently anticipated due to a
number of factors, including those identified in the Company's "Cautionary
Statements" on Exhibit 99 to this Quarterly Report filed on Form 10-Q for the
quarterly period ended June 30, 1998.

GENERAL
Orphan Medical, Inc., a development stage company, was incorporated on June 17,
1994 in order to carry on the business previously conducted by the Orphan
Medical Division of Chronimed. From inception through June 30, 1998, the Company
has incurred losses totaling $30,265,691, consisting of $21,823,377 of research
and development expenses, $5,050,275 of sales and marketing expenses, $7,830,584
of general and administrative expenses, $2,460,811 of gross profit on sales of
approved products and $1,977,734 of net interest income. The Company's
activities have consisted primarily of obtaining the rights for pharmaceutical
products, hiring the personnel required to implement the Company's business
plan, managing the development of these products, preparing for the commercial
introduction of five products and fund raising. At June 30, 1998, five of the
Company's products have been approved by the Food and Drug Administration
("FDA") for marketing and are commercially available and two products were in
development. The Company has not generated sufficient levels of revenue from its
approved products to date to fund its operating activities and has sustained
significant operating losses each year since inception. The Company expects to
continue reporting as a development stage company at least through 1998. In
addition, the Company expects operating losses to continue into 1999.

<PAGE>


SIX MONTHS ENDED JUNE 30, 1998 VS. SIX MONTHS ENDED JUNE 30, 1997
Sales increased from $266,710 for the six months ended June 30, 1997 to
$2,488,601 for the six months ended June 30, 1998. The $2,221,891 increase is
principally attributable to Antizol sales, which the Company commenced shipping
for the first time in December 1997. Antizol sales growth to date reflects the
initial stocking of this product by many hospitals, and the Company expects
sales will fluctuate from quarter to quarter depending, in part, on the
Company's continued success in informing the toxicology and emergency room
communities about the merits of Antizol. Sales of Elliotts B Solution,
Cystadane, and Antizol-Vet are consistent with the Company's expectations.

Cost of sales increased from $120,681 for the six months ended June 30, 1997 to
$391,136 for the six months ended June 30, 1998. The increase of $270,455 is
principally attributable to Antizol sales and to the write-off of excess
inventory quantities of Elliotts B Solution. Cost of sales as a percentage of
sales will fluctuate from quarter to quarter and from year to year depending on,
among other factors, demand for the Company's products, new product
introductions and the mix of approved products shipped.

Research and development expense increased from $2,812,733 (43% of the total
loss from operations) for the six months ended June 30, 1997 to $3,617,961 (88%
of the total loss from operations) for the six months ended June 30, 1998. The
$805,228 increase is largely attributable to higher levels of regulatory and
clinical trial spending for Busulfex and Xyrem. The Company expects research and
development expense, principally clinical trial, regulatory and toxicology
spending, for Busulfex and Xyrem to increase significantly in the second half of
the year. Clinical trial spending for Busulfex and Xyrem will be dependent on a
number of factors, including among others: the number of human subjects required
for a trial, the number of human subjects screened and enrolled in a trial, and
the number of active clinical sites. The Company's product development schedule
for Busulfex and Xyrem, and additional products, if any, that it may develop in
the future will be influenced by regulatory decisions, competitive pressures and
the availability of funding.

Sales and marketing expenses decreased from $2,684,472 (41% of the total loss
from operations) for the six months ended June 30, 1997 to $1,319,843 (32% of
the total loss from operations) for the six months ended June 30, 1998. The
$1,364,629 decrease is principally attributable to a one-time expense of
$2,172,000 (see Note 4 - Chronimed Obligation) incurred during the six months
ended June 30, 1997, partially offset by higher spending related to the addition
of an Antizol sales force, and Antizol sales and marketing program costs
incurred during the six months ended June 30, 1998. Sales and marketing expenses
will likely increase in subsequent quarters.

General and administrative expenses increased from $1,122,549 (17% of the total
loss from operations) for the six months ended June 30, 1997 to $1,263,093 (31%
of the total loss from operations) for the six months ended June 30, 1998. The
$140,544 increase is principally related to executive management consulting
services and staff additions. General and administrative expenses are not
expected to increase significantly in subsequent quarters.

<PAGE>


Other income is the sum of interest income from investment activities less
interest expense from financing activities. Other income decreased from $403,215
for the six months ended June 30, 1997 to $34,279 for the six months ended June
30, 1998. The decrease of $368,936 is due to less interest income resulting from
lower levels of investable funds, which is further reduced by interest expense
of approximately $117,000 related to the Company's obligation to Chronimed.
Other income is expected to increase in subsequent quarters with the addition of
approximately $7.1 million in cash resulting from the July 23, 1998 sale of a
private placement, which will be available for investment as well as funding
development expenses into 1999.

Net losses for the six months ended June 30, 1998 and for the six months ended
June 30, 1997 were $(4,069,153) and $(6,070,510), respectively. Basic and
diluted loss per common share for these respective periods were $(.66) and
$(1.00), based on weighted average number of common shares outstanding of
6,147,145 and 6,062,005, respectively.

LIQUIDITY AND CAPITAL RESOURCES
From inception through June 30, 1998, the Company has used $27,868,890 to fund
operating activities. Since July 2, 1994, the effective date the Company was
spun-off from Chronimed, it has financed its operations principally from initial
working capital balances, the net proceeds from the 1995 and 1996 public
offerings, interest income and product sales. The 1995 and 1996 public offerings
resulted in aggregate net proceeds, after commissions and expenses, of
$23,636,666.

Net working capital (current assets less current liabilities) decreased from
$4,479,714 at December 31, 1997 to $343,881 at June 30, 1998. Cash and cash
equivalents, and available-for-sale securities decreased from $7,169,230 at
December 31, 1997 to $3,684,180 at June 30, 1998. The Company invests excess
cash in short-term, interest-bearing, investment grade securities.

The Company's commitments for outside development spending increased from
approximately $2,700,000 at December 31, 1997 to approximately $3,436,000 at
June 30, 1998. The $736,000 increase resulted principally from accelerating the
Xyrem development program. The Company expects future commitments for Busulfex
and Xyrem to increase significantly over current levels.

The Company has experienced recurring losses from operations and has generated
an accumulated deficit from inception through June 30, 1998 of $30,265,691.
These conditions give rise to the question about the Company's ability to
generate positive cash flow and fund operations. The Company believes that its
current working capital, anticipated gross profits from product sales, and the
$7.1 million in net cash proceeds from the July 23, 1998 sale of a private
placement will be sufficient to fund its operations through December 31, 1999.
These assumptions are based upon the Company substantially increasing
development expenses, increasing revenues from the sale of its Antizol product,
and the successful FDA approval and market launch of Busulfex in the second half
of 1999. Any material reduction in projected revenues and/or a delay in the FDA
approval and market launch of Busulfex will require the

<PAGE>


Company to seek additional equity or debt financing or substantially reduce the
Company's expense structure through reductions in personnel and development.

The Company's ability to raise additional capital and/or raise capital on
acceptable terms could be negatively affected in the event it no longer meets
the Nasdaq's requirements for continued listing on the National Market tier. For
continued listing on the Nasdaq National Market, a company must satisfy a number
of requirements, which in the Company's case includes either: (1) net tangible
assets in excess of $4.0 million as reported on Form 10-Q or Form 10-K or (2) a
market capitalization of at least $50.0 million. At June 30, 1998, the Company's
net tangible assets equaled $669,579 and its market capitalization was
approximately $66.0 million (based on the last sale price of $10.563 and
6,249,718 shares outstanding as of June 30, 1998). Net tangible assets are
defined as total assets less total liabilities. Market capitalization is defined
as total outstanding shares multiplied by the last sales price quoted by Nasdaq.
After giving effect to the July 23, 1998 private placement of Preferred Shares,
which netted the Company approximately $7.1 million in additional net tangible
assets (i.e., cash), the Company estimates that it will have net tangible assets
in excess of the $4.0 million (thereby satisfying Nasdaq's net tangible asset
listing requirement) through at least the end the third quarter of 1998. In the
event UBS Capital exercises its right, which expires on October 21, 1998, to
invest up to an additional $4.5 million, the Company's estimated net tangible
assets are expected to exceed $4.0 million through the end of 1998. Should the
Company fail to satisfy at least one of the two aforementioned Nasdaq listing
requirements at any time after the third quarter of 1998 (or after 1998 in the
event of an additional investment by UBS Capital of at least $2.0 million), the
Company's Common Stock would no longer qualify for listing on the Nasdaq
National Market, but would qualify for quotation on the Nasdaq Small Cap Market
provided it had net tangible assets in excess of $2.0 million.

Item 5. Other Information

On July 17, 1998, the Company announced that Sucraid is commercially available.
The Company will sell Sucraid principally direct to patients through an
affiliate of Cardinal Health, Inc. The Company estimates that annual sales of
Sucraid will be less than $500,000.

On July 23, 1998 (the "First Issuance Date"), the Company received $7,125,000 in
net cash proceeds from the sale of a private placement of $7.5 million of Senior
Convertible Preferred Stock (the "Preferred Shares") to UBS Capital II LLC ("UBS
Capital"), a subsidiary of UBS AG. The private placement agreement also gives
UBS Capital the right to invest up to an additional $4.5 million within 90 days
of the First Issuance Date. The Preferred Shares are convertible, at the option
of the holders, into shares of the Company's Common Stock at a per share price
equal to the lesser of $11.78 or 110% of the average last sale price of the 20
trading days prior to October 21, 1998. The Preferred Shares have anti-dilution
and change of control protection, and bear a dividend of 7.5% per annum, payable
semi annually, which during the first two years may be paid either in cash or by
issuing additional Preferred Shares. In the third year and thereafter, the
dividend may be paid either in cash or by issuing Common Stock valued at the
then current market price. Upon their maturity in July 2008, the Company must
elect to either (1) require the conversion of all unconverted Preferred Shares
into Common Stock upon payment by the Company of a $3.0 million conversion fee,
or redeemed for cash. An affiliate of UBS Capital will be paid on closing a four
percent arrangement fee based on amounts invested. UBS Capital is entitled to
designate an individual to serve on the Company's Board of Directors.

(Pursuant to Minnesota Statutes, Section 302A.401, Subd. 3(b))

- ---------------


         The undersigned, being the Chief Executive Officer of Orphan Medical,
Inc. (the "Corporation"), a corporation organized and existing under the
Minnesota Business Corporation Act, in accordance with the provisions of
Minnesota Statutes, Section 302A.401, Subd. 3(b), does hereby certify that:

         Pursuant to the authority vested in the Board of Directors of the
Corporation by the Articles of Incorporation of the Corporation, the Board of
Directors on July 14, 1998, in accordance with Minnesota Statutes, Section
302A.401, Subd. 3, duly adopted the following resolution establishing a series
of 14,000 shares of the Corporation's Preferred Stock, to be designated as its
Senior Convertible Preferred Stock.

         RESOLVED, that pursuant to the authority vested in the Board of
Directors of the Corporation (the "Board of Directors") by the Articles of
Incorporation of the Corporation, the Board of Directors hereby establishes a
series of Senior Convertible Preferred Stock of the Corporation and hereby
states the designation and number of shares, and fixes the relative rights and
preferences, of such series of shares as follows:

SENIOR CONVERTIBLE PREFERRED STOCK

         Section 1. Designation; Number of Shares. The shares of such series
shall be designated as "Senior Convertible Preferred Stock" (the "Convertible
Preferred Stock"), and the number of authorized shares constituting the
Convertible Preferred Stock shall be 14,000.

         Section 2. Par Value; No Cumulative Voting; No Preemptive Rights. The
Convertible Preferred Stock shall have a par value of $0.01 per share. As
provided in Articles IV and V of the Corporation's Articles of Incorporation,
holders of Convertible Preferred Stock shall not be entitled to cumulate their
votes in any election of directors in which they are entitled to vote and,
except as provided in an agreement between the Corporation and any holder of
Convertible Preferred Stock, shall not be entitled to any preemptive rights to
acquire shares of any class or series of capital stock of the Corporation.

         Section 3. Rank. The Convertible Preferred Stock shall rank prior to
all of the Corporation's Common Stock, par value $0.01 per share (the "Common
Stock") and other classes of preferred stock now outstanding or hereafter
issued, both as to payment of dividends and as to distributions of assets upon
the liquidation, dissolution or winding up of the Corporation, whether voluntary
or involuntary.

         Section 4. Dividends and Distributions.

                  (a) Holders of the Convertible Preferred Stock shall be
entitled to receive, when and as declared by the Board of Directors, cumulative
dividends at the rate, in the form, at the times and in the manner set forth in
this Section 4. Such dividends shall accrue on any given share from the day of
issuance of such share and shall accrue from day to day whether or not earned or
declared.

                  (b) The dividend rate on the Convertible Preferred Stock shall
be $75.00 per annum per share; provided that (i) in the event that at any time
during any 730-day period individuals who constituted the Board of Directors at
the beginning of such period, or the First Issuance Date (as defined in Section
7) (whichever is later), cease for any reason to constitute a majority of the
Board of Directors then in office or (ii) the Board of Directors fails to
declare and pay in full, on any Dividend Payment Date (as defined in Section
4(c)), all dividends accrued since the last Dividend Payment Date (or with
respect to the

<PAGE>


first Dividend Payment Date, since the date of issuance), the dividend rate on
the Convertible Preferred Stock shall be increased to $200 per annum per share
unless holders of a majority of the then outstanding shares of Convertible
Preferred Stock agree to waive such increase. Any change of the dividend rate in
accordance with this Section 4(b) shall be deemed to occur on the date upon
which the event in question occurs. In the event the dividend rate is adjusted
in accordance with this Section 4(b), the Corporation shall pay such dividends
in cash.

                  (c) Dividends shall be payable in arrears, when and as
declared by the Board of Directors on August 1 and February 1 of each year,
commencing February 1, 1999 (each such semiannual payment date, a "Dividend
Payment Date"), except that if any such date is a Saturday, Sunday or legal
holiday then such dividend shall be payable on the first immediately succeeding
calendar day which is not a Saturday, Sunday or legal holiday. Dividends shall
accrue on each share of Convertible Preferred Stock from the date of issuance of
such shares and, after payment of a dividend as required hereunder, from and
after each Dividend Payment Date based on the number of days elapsed and a
365-day year; provided that to the extent that a dividend is not paid in cash or
stock on any Dividend Payment Date as provided in paragraph (d) below such
unpaid amount shall in turn accrue dividends at the rate specified herein until
paid as provided herein. The dividend payable on the first Dividend Payment Date
with respect to any shares of Convertible Preferred Stock shall be the pro rata
portion of the dividend rate based upon the number of days from and including
the date of issuance, up to and including such first Dividend Payment Date and a
365-day year. Each dividend shall be paid to the holders of record of shares of
the Convertible Preferred Stock as they appear on the books of the Corporation
on such record date, not more than sixty (60) days nor fewer than ten (10) days
preceding the respective Dividend Payment Date, as shall be fixed by the Board
of Directors.

                  (d) Any dividend payment made with respect to the Convertible
Preferred Stock, may be made, at the sole discretion of the Board of Directors,
in cash out of funds legally available for such purpose or (i) in respect of
dividends accruing on the Convertible Preferred Stock on or prior to August 1,
2000, by issuing the number of shares of Convertible Preferred Stock equal to
the amount of the dividend divided by $1,000 and (ii) in respect of dividends
accruing on the Convertible Preferred Stock after August 1, 2000, by issuing a
number of shares of Common Stock equal to the amount of the dividend divided by
the average last sale price of the Common Stock for the five (5) trading days
preceding the dividend payment date (the "Dividend Conversion Price"); provided,
that no fractional shares shall be issued; provided, further, that the
Corporation shall pay dividends in cash to the extent that the issuance of stock
would require shareholder approval pursuant to Section 4460(i) of the Rules of
the NASDAQ Stock Market or any successor rule thereto and such approval has not
been obtained. Any such dividend payment may be made, in the sole discretion of
the Board of Directors, partially in cash and partially in shares of Convertible
Preferred Stock or Common Stock, as applicable, determined in accordance with
the preceding formula; provided, that in the event that any such dividend
payment is made partially in cash and partially in shares of Convertible
Preferred Stock or Common Stock, each holder of Convertible Preferred Stock
shall receive a ratable amount of cash and Convertible Preferred Stock or Common
Stock, as the case may be, that is proportionate to the amount of Convertible
Preferred Stock held by such holder on which such dividend is paid. If any
fractional interest in a share of Convertible Preferred Stock or Common Stock
would be delivered upon any payment of dividends pursuant to this Section 4, the
Corporation, in lieu of delivering the fractional share of Convertible Preferred
Stock or Common Stock shall pay an amount to the holder thereof equal to such
fraction multiplied by $1,000 or equal to the Dividend Conversion Price, as
applicable. All shares of Convertible Preferred Stock and Common Stock issued as
a dividend shall be fully paid and nonassessable.

                  (e) No dividends or other distributions (other than dividends
payable in Junior Dividend Stock (as defined below)) shall be paid or set apart
for payment on, and no purchase, redemption or other acquisition shall be made
by the Corporation, or any of its subsidiaries, of, any shares of Common Stock
or other capital stock of the Corporation ranking junior as to payment of
dividends on the Convertible Preferred Stock (such Common Stock and other
capital stock being referred to herein collectively as "Junior Dividend Stock");
provided that dividends or other distributions may be paid or set

<PAGE>


apart for payment on any shares of Junior Dividend Stock at such time as less
than 20% of the Denominator Shares (as defined in Section 6(b)) remain
outstanding. Any reference to "distribution" contained in this Section 4 shall
not be deemed to include any distribution made in connection with a liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary.

         Section 5. Liquidation Preference. In the event of a liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
the holders of Convertible Preferred Stock shall be entitled to receive out of
the assets of the Corporation an amount equal to the dividends accumulated and
unpaid thereon to the date of final distribution to such holders, whether or not
declared, without interest, plus a sum equal to $1,000 per share, and no more,
before any payment shall be made or any assets distributed to the holders of
Common Stock or any other capital stock of the Corporation ranking junior as to
liquidation rights to the Convertible Preferred Stock (such Common Stock and
other capital stock being referred to herein collectively as "Junior Liquidation
Stock"). The entire assets of the Corporation available for distribution shall
be distributed ratably among the holders of the Convertible Preferred Stock.
After payment in full of the liquidation preference of the shares of the
Convertible Preferred Stock, the holders of such shares shall not be entitled to
any further participation in any distribution of assets by the Corporation.
Neither a consolidation or merger of the Corporation with another corporation
nor a sale or transfer of all or part of the Corporation's assets for cash,
securities or other property will be deemed a liquidation, dissolution or
winding up of the Corporation for purposes of this Section 5.

         Section 6. Ten Year Conversion or Redemption.

                  (a) On the tenth anniversary (the "Anniversary Date") of the
First Issuance Date (as defined in Section 7), the Corporation, at its election,
shall either require the conversion of all then issued and outstanding shares of
Convertible Preferred Stock into fully paid and nonassessable shares of Common
Stock at the Conversion Price (the "Anniversary Conversion") or redeem the then
issued and outstanding shares of Convertible Preferred Stock (the "Redemption")
as provided below.

                  (b) If the Corporation elects the Anniversary Conversion, the
Corporation shall pay a conversion fee equal to $3,000,000 (the "Conversion
Fee"), subject to adjustment, on a pro rata basis to the holders of the then
issued and outstanding shares of Convertible Preferred Stock. The Corporation
shall pay the Conversion Fee, at the election of the Board of Directors, in (i)
cash or (ii) a number of shares of Common Stock equal to the Conversion Fee
divided by the average last sale price of the Common Stock for the five (5)
trading days immediately preceding the Anniversary Date; provided, however, that
the Corporation shall pay the Conversion Fee in cash to the extent that the
issuance of stock would require shareholder approval pursuant to Section 4460(i)
of the Rules of the NASDAQ Stock Market or any successor rule thereto and such
approval has not been obtained. In the event that the number of shares of
Convertible Preferred Stock issued and outstanding as of the Anniversary Date is
less than the sum of the number of Initial Shares (as defined in Section 7(b)
below) and shares issued as dividends, if any, on the Convertible Preferred
Stock (such sum is hereinafter referred to as the "Denominator Shares") pursuant
to Section 4 hereof, then the Conversion Fee will be adjusted downward to equal
the product of (a) $3,000,000 and (b) the quotient of the number of shares of
Convertible Preferred Stock issued and outstanding as of the Anniversary Date
divided by the Denominator Shares (as adjusted for any stock split, stock
dividend, recapitalization or otherwise). On or after the Anniversary Date, each
holder of Convertible Preferred Stock shall surrender the certificate or
certificates evidencing such shares to the Corporation and the Corporation shall
deliver to such holder (i) a certificate or certificates representing the number
of shares of Common Stock equal to the number of shares of Convertible Preferred
Stock to be converted multiplied by $1,000 divided by the Conversion Price set
forth in the notice to the holder, (ii) the holder's pro rata portion of the
Conversion Fee and (iii) accrued and unpaid dividends in cash or a number of
shares of Common Stock equal to the dividend amount divided by the Conversion
Price. In addition, the following provisions of Section 7 shall be applicable to
the Anniversary Conversion: the second sentence of the second paragraph of
Section 7(a), third paragraph of Section 7(b), Section 7(d) and Section 7(e).

<PAGE>


                  (c) In the event the Corporation elects a Redemption, the
Corporation shall redeem for cash on the Anniversary Date all issued and
outstanding shares of Convertible Preferred Stock at a price per share equal to
$1,000 plus all accrued and unpaid dividends on such share to the Anniversary
Date (such sum being hereinafter referred to as the "Redemption Price"). On or
after the Anniversary Date, each holder of Convertible Preferred Stock shall
surrender the certificate or certificates evidencing such shares to the
Corporation at the place designated in the notice to the holder and shall
thereupon be entitled to receive payment of the Redemption Price. If, on the
Anniversary Date, funds necessary for the Redemption shall be available therefor
and shall have been irrevocably deposited or set aside, then, notwithstanding
that the certificates evidencing any shares so called for redemption shall not
have been surrendered, on the Anniversary Date, the dividends with respect to
the shares so called shall cease to accrue, such shares shall no longer be
deemed outstanding, the holders thereof shall cease to be shareholders and all
rights whatsoever with respect to such shares (except the right of the holders
thereof to receive the Redemption Price upon surrender of their certificates)
shall terminate.

                  (d) No more than sixty (60) nor less than twenty (20) days
prior to the Anniversary Date, the Corporation shall deliver notice, by first
class mail, postage prepaid, to each holder of record of the Convertible
Preferred Stock, addressed to such shareholder at its last address as shown on
the stock books of the Corporation. Such notice shall state whether the
Corporation has elected to effect the Anniversary Conversion or the Redemption.
If the Corporation fails to give notice as provided above, the Corporation shall
be deemed to have elected the Redemption. In the event of the Anniversary
Conversion, the notice shall also state that the Anniversary Date is the date
fixed for conversion, the then-effective Conversion Price (as defined in Section
7), whether the Conversion Fee will be paid in cash or shares of Common Stock
and the holder's pro rata portion of such, whether the accumulated and unpaid
dividends to the Anniversary Date will be paid in cash or shares of Common Stock
and that on and after the Anniversary Date, dividends will cease to accumulate
on such shares of Convertible Preferred Stock; provided that there is no default
in the payment of the Conversion Fee. In the event of the Redemption, the notice
shall also state that the Anniversary Date is the date fixed for redemption, the
Redemption Price, the place or places of payment, that the right of holders of
Convertible Preferred Stock to exercise their conversion rights in accordance
with Section 7 shall expire at the close of business on the Anniversary Date
(provided that there is no default in payment of the Redemption Price) and that
payment of the Redemption Price will be made upon presentation and surrender of
certificates representing the Convertible Preferred Stock to the Corporation or
its agent as provided in the notice

         Section 7. Conversion.

                  (a) Holders of Convertible Preferred Stock may, at their
option upon surrender of the certificates therefor, convert any or all of their
shares of Convertible Preferred Stock into fully paid and nonassessable shares
of Common Stock (and such other securities and property as they may be entitled
to, as hereinafter provided) at any time after issuance thereof; provided, that
such conversion right shall expire at the close of business on the date, if any,
fixed for the redemption of Convertible Preferred Stock in any notice of
redemption given pursuant to Section 6 hereof if there is no default in payment
of the Redemption Price. Each share of Convertible Preferred Stock shall be
convertible at the office of any transfer agent for the Convertible Preferred
Stock, and at such other office or offices, if any, as the Board of Directors
may designate, into that number of fully paid and nonassessable shares of Common
Stock (calculated as to each conversion to the nearest whole share) as shall be
equal to $1,000 divided by the Conversion Price (as defined below) in effect at
the time of conversion. The initial Conversion Price will be the lesser of (i)
110% of the average last sale price of the Common Stock for the twenty (20)
trading days immediately prior to July 23, 1998 (the "First Issuance Date") or,
(ii) 110% of the average last sale price of the Common Stock for the twenty (20)
days immediately prior to the date that is ninety (90) days from the First
Issuance Date of the Convertible Preferred Stock, subject to adjustment from
time to time as provided in Section 8 (such conversion rate, as so adjusted from
time to time, being referred to herein as the "Conversion Price"); provided,
that in no event shall the initial Conversion Price (prior to any adjustment
provided in Section 8) be less than $8.50.

<PAGE>


                  The right of holders of Convertible Preferred Stock to convert
their shares shall be exercised by surrendering for such purpose to the
Corporation or its agent, as provided above, certificates representing shares to
be converted, duly endorsed in blank or accompanied by proper instruments of
transfer. The Corporation shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issue and delivery of Common
Stock or other securities or property upon conversion of Convertible Preferred
Stock in a name other than that of the holder of the shares of Convertible
Preferred Stock being converted, nor shall the Corporation be required to issue
or deliver any such shares or other securities or property unless and until the
person or persons requesting the issuance thereof shall have paid to the
Corporation the amount of any such tax or shall have established to the
satisfaction of the Corporation that such tax has been paid.

                  (b) In the event the Common Stock trades above $40 per share
for ninety (90) consecutive trading days and the average daily reported volume
in trading for the Common Stock on all national securities exchanges and/or
reported through the automated quotation system of a registered securities
association for any twenty (20) consecutive trading days during such 90-day
period exceeds 10% of the number of shares of Common Stock into which the sum of
the number of shares of Convertible Preferred Stock issued on the First Issuance
Date and the additional shares of Convertible Preferred Stock issued to such
holders within one hundred twenty (120) days after the First Issuance Date (the
"Initial Shares") could be converted, adjusted to eliminate the effect of any
reporting of both the buy and sell side of any trade, the Corporation may, by
notice to the holders thereof, within thirty (30) days after such 90-day period,
elect to require the conversion of all the shares of Convertible Preferred Stock
then outstanding into fully paid and nonassessable shares of Common Stock at the
applicable Conversion Price.

                  Such notice shall be delivered by first class mail, postage
prepaid, shall be given to the holders of record of the Convertible Preferred
Stock to be converted, addressed to such shareholders at their last addresses as
shown on the stock books of the Corporation. Each such notice of conversion
shall specify the date fixed for conversion; the then-effective Conversion
Price; that accumulated but unpaid dividends to the date fixed for conversion
will be paid, at the election of the Board of Directors, in cash or in a number
of shares of Common Stock equal to the dividend amount divided by the Conversion
Price on the date fixed for conversion (which shall be within thirty (30) days
of the notice); and that on and after the conversion date, dividends will cease
to accumulate on such shares.

                  Any notice which is mailed as herein provided shall be
conclusively presumed to have been duly given, whether or not a holder of the
Convertible Preferred Stock receives such notice; and failure so to give such
notice, or any defect in such notice, to the holders of any shares designated
for conversion shall not affect the validity of the proceedings for the
conversion of any other shares of Convertible Preferred Stock.

                  (c) A number of shares of the authorized but unissued Common
Stock sufficient to provide for the conversion of the Convertible Preferred
Stock outstanding upon the basis hereinbefore provided shall at all times be
reserved by the Corporation, free from preemptive rights, for such conversion,
subject to the provisions of the next paragraph. If the Corporation shall issue
any securities or make any change in its capital structure which would change
the number of shares of Common Stock into which each share of the Convertible
Preferred Stock shall be convertible as herein provided, the Corporation shall
at the same time also make proper provision so that thereafter there shall be a
sufficient number of shares of Common Stock authorized and reserved, free from
preemptive rights, for conversion of the outstanding Convertible Preferred Stock
on the new basis. The Corporation shall comply with all securities laws
regulating the offer and delivery of shares of Common Stock upon conversion of
the Convertible Preferred Stock and shall use its best efforts to list such
shares on each national securities exchange on which the Common Stock is listed
or to have such shares admitted for quotation on the NASDAQ National Market
System if the Common Stock is admitted for quotation thereon.

                  (d) Upon the surrender of certificates representing shares of
Convertible Preferred Stock to be converted, duly endorsed or accompanied by
proper instruments of transfer as provided above,

<PAGE>


the person converting such shares shall be deemed to be the holder of record of
the Common Stock issuable upon such conversion, and all rights with respect to
the shares surrendered shall forthwith terminate except the right to receive the
Common Stock or other securities, cash or other assets as herein provided.

                  (e) No fractional shares of Common Stock shall be issued upon
conversion of Convertible Preferred Stock but, in lieu of any fraction of a
share of Common Stock which would otherwise be issuable in respect of the
aggregate number of such shares surrendered for conversion at one time by the
same holder, the Corporation shall pay in cash an amount equal to the product of
(a)the Closing Price of a share of Common Stock (as defined in the next
sentence) on the last trading day before the conversion date and (b)such
fraction of a share. The "Closing Price" for each day shall be the last reported
sale price or, in case no sale takes place on such day, the average of the
closing bid and asked price on such day, in either case as reported on the New
York Stock Exchange Composite Tape, or, if the Common Stock is not listed or
admitted to trading on such Exchange, on the principal national securities
exchange on which the Common Stock is listed or admitted to trading, or, if the
Common Stock is not listed or admitted to trading on any national securities
exchange, on the NASDAQ National Market System, or, if the Common Stock is not
admitted for quotation on the NASDAQ National Market System, the average of the
high bid and low asked prices on such day as recorded by the National
Association of Securities Dealers, Inc. through NASDAQ, or, if the National
Association of Securities Dealers, Inc. through NASDAQ shall not have reported
any bid and asked prices for the Common Stock on such day, the average of the
bid and asked prices for such day as furnished by any New York Stock Exchange
member firm selected from time to time by the Corporation for such purpose, or,
if no such bid and asked prices can be obtained from any such firm, the fair
market value of one share of the Common Stock on such day as determined in good
faith by the Board of Directors of the Corporation.

         Section 8. Adjustments to Conversion Price. Notwithstanding anything in
this Section 8 to the contrary, no change in the Conversion Price shall be made
until the cumulative effect of the adjustments called for by this Section8 since
the date of the last change in the Conversion Price would change the Conversion
Price by more than 1%. However, once the cumulative effect would result in such
a change, then the Conversion Price shall be changed to reflect all adjustments
called for by this Section8 and not previously made. Additionally, there shall
be no adjustment in the Conversion Price as a result of any issue or sale (or
deemed issue or sale) of (i)(A)shares of Common Stock that may be issued after
the First Issuance Date to Chronimed, Inc. pursuant to the terms of the
Termination Agreement between the Corporation and Chronimed, Inc., (B) shares of
Common Stock that may be issued upon exercise of stock options that are
outstanding on the First Issuance Date (as such number of shares is
proportionately adjusted for subsequent stock splits, combinations of shares and
stock dividends affecting the Common Stock), in each case pursuant to the terms
thereof as in effect on the First Issuance Date, and (C) stock options and
shares of Common Stock issuable upon exercise of such options granted to
employees and directors of the Corporation and its Subsidiaries pursuant to the
terms of stock option plans approved by the Corporation's Board of Directors if
such options are exercisable at the market price on the date of grant; provided
that the aggregate number of shares of Common Stock issued, or issuable,
pursuant to this clause (i) shall not exceed two million shares, (ii) Common
Stock upon the exercise of warrants that, as of June 30, 1998, entitled holders
to purchase an aggregate of 213,255 shares of Common Stock (which warrants were
originally issued on May 19, 1995 to R.J. Steichen & Company and a portion of
which were subsequently assigned to employees and affiliates of R.J. Steichen &
Company), (iii) Common Stock upon the conversion or exchange of the Preferred
Stock or (iv) securities pursuant to any public offering of the Company's
securities registered under the Securities Act (collectively referred to as
"Permitted Issuances"). Subject to the foregoing, the Conversion Price shall be
adjusted from time to pursuant to Section 8(a).

                  (a) If and whenever, on or after the First Issuance Date, the
Corporation issues or sells, or in accordance with this Section 8(a) is deemed
to have issued or sold, any shares of its Common Stock for consideration per
share less than the Conversion Price in effect immediately prior to the time of
such issue or sale, then, unless such issuance or sale was a Permitted Issuance,
immediately upon such

<PAGE>


issue or sale or deemed issue or sale the Conversion Price shall be reduced to
the Conversion Price determined by dividing (i) the sum of (1) the product
derived by multiplying the Conversion Price in effect immediately prior to such
issue or sale by the number of shares of Common Stock deemed outstanding
immediately prior to such issue or sale, plus (2) the consideration, if any,
received by the Corporation upon such issue or sale, by (ii) the number of
shares of Common Stock deemed outstanding immediately after such issue or sale.

                           (i) Issuance of Rights or Options. If the Corporation
in any manner grants or sells any options and the price per share for which
Common Stock is issuable upon the exercise of such options, or upon conversion
or exchange of any convertible securities issuable upon exercise of such
options, is less than the Conversion Price in effect immediately prior to the
time of the granting or sale of such options, then, unless such issuance or sale
was a Permitted Issuance, the total maximum number of shares of Common Stock
issuable upon the exercise of such options or upon conversion or exchange of the
total maximum amount of such convertible securities issuable upon the exercise
of such options shall be deemed to be outstanding and to have been issued and
sold by the Corporation at the time of the granting or sale of such options for
such price per share. For purposes of this paragraph, the "price per share for
which Common Stock is issuable" shall be determined by dividing (i) the total
amount, if any, received or receivable by the Corporation as consideration for
the granting or sale of such options, plus the minimum aggregate amount of
additional consideration payable to the Corporation upon exercise of all such
options, plus in the case of such options which relate to convertible
securities, the minimum aggregate amount of additional consideration, if any,
payable to the Corporation upon the issuance or sale of such convertible
securities and the conversion or exchange thereof, by (ii) the total maximum
number of shares of Common Stock issuable upon the exercise of such options or
upon the conversion or exchange of all such convertible securities issuable upon
the exercise of such options. No further adjustment of the Conversion Price
shall be made when convertible securities are actually issued upon the exercise
of such options or when Common Stock is actually issued upon the exercise of
such options or the conversion or exchange of such convertible securities.

         (ii) Issuance of Convertible Securities. If the Corporation in any
manner issues or sells any convertible securities and the price per share for
which Common Stock is issuable upon conversion or exchange thereof is less than
the Conversion Price in effect immediately prior to the time of such issue or
sale, then, unless such issuance or sale is a Permitted Issuance, the maximum
number of shares of Common Stock issuable upon conversion or exchange of such
convertible securities shall be deemed to be outstanding and to have been issued
and sold by the Corporation at the time of the issuance or sale of such
convertible securities for such price per share. For the purposes of this
paragraph, the "price per share for which Common Stock is issuable" shall be
determined by dividing (i) the total amount received or receivable by the
Corporation as consideration for the issue or sale of such convertible
securities, plus the minimum aggregate amount of additional consideration, if
any, payable to the Corporation upon the conversion or exchange thereof, by (ii)
the total maximum number of shares of Common Stock issuable upon the conversion
or exchange of all such convertible securities. No further adjustment of the
Conversion Price shall be made when Common Stock is actually issued upon the
conversion or exchange of such convertible securities, and if any such issue or
sale of such convertible securities is made upon exercise of any options for
which adjustments of the Conversion Price had been or are to be made pursuant to
other provisions of this Section 8(a) no further adjustment of the Conversion
Price shall be made by reason of such issue or sale.

                           (iii) Change in Option Price or Conversion Rate. If
the purchase price provided for in any options, the additional consideration, if
any, payable upon the conversion or exchange of any convertible securities or
the rate at which any convertible securities are convertible into or
exchangeable for Common Stock changes at any time, the Conversion Price in
effect at the time of such change shall be immediately adjusted to the
Conversion Price which would have been in effect at such time had such options
or convertible securities still outstanding provided for such changed purchase
price, additional consideration or conversion rate, as the case may be, at the
time initially granted, issued or sold; provided that in no event shall the
Conversion Price be adjusted to a price higher than the Conversion Price 

<PAGE>


in effect prior to any actions described in this Section 8(a)(iii). For purposes
of this Section 8(a)(iii) if the terms of any option or convertible security
which was outstanding as of the First Issuance Date are changed in the manner
described in the immediately preceding sentence, then such option or convertible
security and the Common Stock deemed issuable upon exercise, conversion or
exchange thereof shall be deemed to have been issued as of the date of such
change and no such change shall cause the Conversion Price hereunder to be
increased.

                           (iv) Treatment of Expired Options and Unexercised
Convertible Securities. Upon the expiration of any option or the termination of
any right to convert or exchange any convertible security without the exercise
of any such option or right, the Conversion Price then in effect hereunder shall
be adjusted immediately to the Conversion Price which would have been in effect
at the time of such expiration or termination had such option or convertible
security, to the extent outstanding immediately prior to such expiration or
termination, never been issued. For purposes of this Section 8(a) the expiration
or termination of any option or convertible security which was outstanding as of
the First Issuance Date shall not cause the Conversion Price hereunder to be
adjusted unless, and only to the extent that, a change in the terms of such
option or convertible security caused it to be deemed to have been issued after
the First Issuance Date. For purposes of this Section 8(a)(iv) if the terms of
any expired option or termination of any right to convert or exchange any
convertible security which was outstanding as of the First Issuance Date are
changed in the manner described in Section 8(a)(iii), then such option or
convertible security and the Common Stock deemed issuable upon exercise,
conversion or exchange thereof shall be deemed to have been issued as of the
date of such change and no such change shall cause the Conversion Price
hereunder to be increased.

                           (v) Calculation of Consideration Received. If any
Common Stock, option or convertible security is issued or sold or deemed to have
been issued or sold for cash, the consideration received therefor shall be
deemed to be the amount received by the Corporation therefor (net of discounts,
commissions and related expenses). If any Common Stock, option or convertible
security is issued or sold for a consideration other than cash, the amount of
the consideration other than cash received by the Corporation shall be the fair
value of such consideration, except where such consideration consists of
securities, in which case the amount of consideration received by the
Corporation shall be the fair market price (calculated to be the average Closing
Price for the twenty (20) trading days immediately prior to the date of sale of
the securities described in the first sentence of this Section 8(a)(v)) thereof
as of the date of receipt. If any Common Stock, option or convertible Security
is issued to the owners of the non-surviving entity in connection with any
merger in which the Corporation is the surviving corporation, the amount of
consideration therefor shall be deemed to be the fair value of such portion of
the net assets and business of the non-surviving entity as is attributable to
such Common Stock, option or convertible security, as the case may be. The fair
value of any consideration other than cash and securities shall be determined
jointly by the Corporation and the holders of a majority of the outstanding
Convertible Preferred Stock. If such parties are unable to reach agreement
within a reasonable period of time, the fair value of such consideration shall
be determined by an independent appraiser experienced in valuing such type of
consideration jointly selected by the Corporation and the holders of a majority
of the outstanding Convertible Preferred Stock. The determination of such
appraiser shall be final and binding upon the parties, and the fees and expenses
of such appraiser shall be borne by the Corporation.

         (vi) Integrated Transactions. In case any option is issued in
connection with the issue or sale of other securities of the Corporation,
together comprising one integrated transaction in which no specific
consideration is allocated to such option by the parties thereto, the option
shall be deemed to have been issued for a consideration of $.00.

                           (vii) Treasury Shares. The number of shares of Common
Stock outstanding at any given time shall not include shares owned or held by or
for the account of the Corporation or any Subsidiary, and the disposition of any
shares so owned or held shall be considered an issue or sale of Common Stock.

<PAGE>


                           (viii) Record Date. If the Corporation takes a record
of the holders of Common Stock for the purpose of entitling them (i) to receive
a dividend or other distribution payable in Common Stock, options or in
convertible securities or (ii) to subscribe for or purchase Common Stock,
options or convertible securities, then such record date shall be deemed to be
the date of the issue or sale of the shares of Common Stock deemed to have been
issued or sold upon the declaration of such dividend or upon the making of such
other distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

                  (b) Subdivision or Combination of Common Stock. If the
Corporation at any time subdivides (by any stock split, stock dividend,
recapitalization or otherwise) one or more classes of outstanding shares of
Common Stock into a greater number of shares, the Conversion Price in effect
immediately prior to such subdivision, or any applicable record date shall be
proportionally reduced, and if the Corporation at any time combines (by reverse
stock split or otherwise) one or more classes of its outstanding shares of
Common Stock into a smaller number of shares, the Conversion Price in effect
immediately prior to such combination or any applicable record date shall be
proportionately increased.

                  (c) Reorganization, Reclassification, Consolidation, Merger or
Sale. Any recapitalization, reclassification, consolidation, merger, sale of all
or substantially all of the Corporation's assets or other transaction, in each
case which is effected in such a manner that the holders of Common Stock are
entitled to receive (either directly or upon subsequent liquidation) stock,
securities or assets with respect to or in exchange for Common Stock, is
referred to herein as an "Organic Change." Prior to the consummation of any
Organic Change, the Corporation shall make appropriate provisions (in form and
substance satisfactory to the holders of a majority of the Convertible Preferred
Stock then outstanding) to insure that each of the holders of Convertible
Preferred Stock shall thereafter have the right to acquire and receive, in lieu
of or in addition to (as the case may be) the shares of Common Stock immediately
theretofore acquirable and receivable upon the conversion of such holder's
Convertible Preferred Stock, such shares of stock, securities or assets as such
holder would have received in connection with such Organic Change if such holder
had converted its Convertible Preferred Stock immediately prior to such Organic
Change, or any applicable record date thereon. In each such case, the
Corporation shall also make appropriate provisions (in form and substance
satisfactory to the holders of a majority of the Convertible Preferred Stock
then outstanding) to insure that the provisions of this Section 8 shall
thereafter be applicable to the Convertible Preferred Stock (including, in the
case of any such consolidation, merger or sale in which the successor entity or
purchasing entity is other than the Corporation an immediate adjustment of the
Conversion Price to the value for the Common Stock reflected by the terms of
such consolidation, merger or sale, and a corresponding immediate adjustment in
the number of shares of Common Stock acquirable and receivable upon conversion
of Convertible Preferred Stock, if the value so reflected is less than the
Conversion Price in effect immediately prior to such consolidation, merger or
sale). The Corporation shall not effect any such consolidation, merger or sale,
unless prior to the consummation thereof, the successor entity (if other than
the Corporation) resulting from consolidation or merger or the entity purchasing
such assets assumes by written instrument (in form and substance reasonably
satisfactory to the holders of a majority of the Convertible Preferred Stock
then outstanding), the obligation to deliver to each such holder such shares of
stock, securities or assets as, in accordance with the foregoing provisions,
such holder may be entitled to acquire.

                  (d) Certain Events. If any event occurs of the type
contemplated by the provisions of this Section 8 but not expressly provided for
by such provisions (including, without limitation, the granting of stock
appreciation rights, phantom stock rights or other rights with equity features),
then the Corporation's Board of Directors shall make an appropriate adjustment
in the Conversion Price so as to protect the rights of the holders of
Convertible Preferred Stock; provided that no such adjustment shall increase the
Conversion Price as otherwise determined pursuant to this Section 8 or decrease
the number of shares of Common Stock issuable upon conversion of each share of
Convertible Preferred Stock.

                  (e) Notices.

<PAGE>


                           (i) Promptly after any adjustment of the Conversion
Price, the Corporation shall give written notice thereof to all holders of

the calculation of such adjustment.

                           (ii) The Corporation shall give written notice to all
holders of Convertible Preferred Stock at least twenty (20) days prior to the
date on which the Corporation closes its books or takes a record (a) with
respect to any dividend or distribution upon Common Stock, (b) with respect to
any pro rata subscription offer to holders of Common Stock or (c) for
determining rights to vote with respect to any Organic Change, dissolution or

Holders or Exchangeable; No Sinking Fund. The Convertible Preferred Stock shall
not be redeemable upon the request of holders thereof or exchangeable for other
capital stock (except for Common Stock upon conversion as provided herein) or
indebtedness of the Corporation or other property. The Convertible Preferred
Stock shall not be subject to the operation of a purchase, retirement or sinking
fund.

         Section 10. Voting Rights. So long as 20% of the Initial Shares remain
outstanding, the holders of a majority of the Convertible Preferred Stock,
voting separately as a single class in the election of directors of the
Corporation, to the exclusion of all other classes of the Corporation's capital
stock and with each share of Convertible Preferred Stock entitled to one vote,
shall be entitled to elect one (1) director (the "Preferred Stock
Representative") to serve on the Corporation's Board of Directors until his
successor is duly elected by holders of a majority of the Convertible Preferred
Stock or he is removed from office by holders of a majority of the Convertible
Preferred Stock. If the holders of a majority of the Convertible Preferred Stock
for any reason fail to elect anyone to fill such directorship, such position
shall remain vacant until such time as the holders of a majority of the
Convertible Preferred Stock elect a director to fill such position and shall not
be filled by resolution or vote of the Corporation's Board of Directors or the
Corporation's other stockholders.

         The holders of the Convertible Preferred Stock shall vote separately as
a single class, and approval of holders of a majority of the outstanding shares
of Convertible Preferred Stock shall be required, whenever a shareholder vote is
required pursuant to Section 302A.671 of the Minnesota Business Corporation Act,
or any successor provision thereto, for the purpose of according voting rights
with respect to shares acquired or to be acquired in a control share acquisition
(as defined in Section 302A.011 Subdivision 38 of the Minnesota Business
Corporation Act).

         The holders of the Convertible Preferred Stock shall be entitled to
notice of all stockholders' meetings in accordance with the Corporation's
bylaws, and except in the election of directors and as otherwise provided
herein, the holders of the Convertible Preferred Stock shall be entitled to vote
on all matters submitted to the stockholders for a vote together with the
holders of the Common Stock voting together as a single class with each share of
Common Stock entitled to one vote per share and each share of Convertible
Preferred Stock entitled to one vote for each share of Common Stock issuable
upon conversion of the Convertible Preferred Stock as of the record date for
such vote or, if no record date is specified, as of the date of such vote.

         Section 11. Certain Actions Not to be Taken Without Vote of Holders of
Convertible Preferred Stock. So long as the Convertible Preferred Stock is
outstanding, the Corporation shall not, without first obtaining the affirmative
vote or written consent of holders of a majority of the then issued and
outstanding shares of Convertible Preferred Stock, voting as a single class:

or cash distribution or other payment upon the Junior Dividend Stock, nor

Corporation pursuant to a stock option plan approved by the Corporation's Board
of Directors; provided that dividends or other distributions may be paid or set
apart for payment on any shares of Junior Dividend Stock at such time as less
than 20% of the Denominator Shares remain outstanding;

                  (e) authorize or permit the Corporation or any subsidiary of
the Corporation to issue any equity securities except for Permitted Issuances
and payment of dividends as provided in Section 4 above;

                  (f) incur any indebtedness unless after giving effect to the
additional indebtedness the aggregate indebtedness of the Corporation and its
subsidiaries outstanding as of the date of such incurrence (the "Determination
Date"), excluding financing that is secured by accounts receivable but not by
the Corporation's intellectual property licenses or other intellectual property

unless such transaction was approved by a majority of disinterested members of
the Board of Directors, including the Preferred Stock Representative.

         Section 12. Outstanding Shares. For purposes of this Certificate of
Designations, all shares of Convertible Preferred Stock shall be deemed
outstanding except for (a) shares of Convertible Preferred Stock held of record
or beneficially by the Corporation or any subsidiary of the Corporation; (b)
from the date of surrender of certificates representing Convertible Preferred
Stock for conversion pursuant to Section 7, all shares of Convertible Preferred
Stock which have been converted into Common Stock or other securities or
property pursuant to Section 7; and (c) from the date fixed for redemption
pursuant to Section 6, all shares of Convertible Preferred Stock which have been
called for redemption, provided that

<PAGE>


funds necessary for such redemption are available therefor and have been
irrevocably deposited or set aside for such purpose.

         Section 13. Status of Convertible Preferred Stock Upon Retirement.
Shares of Convertible Preferred Stock which are acquired or redeemed by the
Corporation or converted pursuant to Section 7 shall return to the status of
authorized and unissued shares of Preferred Stock of the Corporation without
designation as to series. Upon the acquisition or redemption by the Corporation
or conversion pursuant to Section 7 of all outstanding shares of Convertible
Preferred stock, all provisions of this Certificate of Designation shall cease
to be of further effect. Upon the occurrence of such event, the Board of
Directors of the Corporation shall have the power, pursuant to Minnesota
Statutes, Section 302A.135, Subd. 5 or any successor provision and without
shareholder action, to cause restated articles of incorporation of the
Corporation or other appropriate documents to be prepared and filed with the
Secretary of State of the State of Minnesota which reflect such removal of all
provisions relating to the Convertible Preferred Stock and/or the cancellation
of this Certificate of Designations.

or for the account of Borrower under this Agreement is subject to the following
conditions precedent, with all documents, instruments, opinions, reports, and

similar default within the preceding twelve (12) months, it may be cured (and no
Event of Default will have occurred) if Borrower or Grantor, as the case may be,

Borrower, except that in the case of an Event of Default of the type described
in the "Insolvency" subsection above, such acceleration shall be automatic and
not optional. In addition, Lender shall have all the rights and remedies
provided in the Related Documents or available at law, in equity, or otherwise.

remedies shall be cumulative and may be exercised singularly or concurrently.

declare a default and to exercise its rights and remedies.

BANK ("Lender"), or order, In lawful money of the United States of America, the
principal amount of Five Hundred Thousand & 001100 Dollars ($500,000.00) or so
much as may be outstanding, together with Interest on the unpaid outstanding
principal balance of each advance. Interest shall be calculated from the date of
each advance until repayment of each advance.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal
plus all accrued unpaid Interest on May 15, 1999. in addition, Borrower will pay
regular monthly payments of accrued unpaid Interest beginning June 15, 1998, and
all subsequent interest payments are due on the same day of each month after
that. The annual interest rate for this Note is computed on a 365/360 basis;
that is, by applying the ratio of the annual interest rate over a year of 360
days, multiplied by the outstanding principal balance, multiplied by the actual
number of days the principal balance is outstanding. Borrower will pay Lender at
Lender's address shown above or at such other place as Lender may designate in
writing. Unless otherwise agreed or required by applicable law, payments will be
applied first to accrued unpaid interest, then to principal, and any remaining
amount to any unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in an independent index which is the PRIME RATE OF
INTEREST AS PUBLISHED EACH BUSINESS DAY IN THE MONEY RATES SECTION OF THE WALL
STREET JOURNAL (the"Index"). The Index is not necessarily the lowest rate
charged by Lender on its loans. If the Index becomes unavailable during the term
of this loan, Lender may designate a substitute index after notice to Borrower.
Lender will tell Borrower the current index rate upon Borrower's request.
Borrower understands that Lender may make loans based on other rates as well.
The interest rate change will not occur more often than each DAY. The Index
currently is 8.500% per annum. The interest rate to be applied to the unpaid
principal balance of this Note will be at a rate of 0.500 percentage points over
the Index, resulting in an Initial rate of 9.000% per annum. NOTICE: Under no
circumstances will the interest rate on this Note be more than the maximum rate
allowed by applicable law.

PREPAYMENT. Borrower agrees that all loan fees and other prepaid finance charges
are earned fully as of the date of the loan and will not be subject to refund
upon early payment (whether voluntary or as a result of default), except as
otherwise required by law. Except for the foregoing, Borrower may pay without
penalty all or a portion of the amount owed earlier than it is due. Early
payments will not, unless agreed to by Lender in writing, relieve Borrower of
Borrower's obligation to continue to make payments of accrued unpaid interest.
Rather, they will reduce the principal balance due.

LATE CHARGE. If a payment is 10 days or more late, Borrower will be charged
5.000% of the unpaid portion of the regularly scheduled payment.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise

shall deposit with Lender cash, a sufficient corporate surety bond or other
security satisfactory to Lender in an amount adequate to provide for the
discharge of the lien plus any interest, costs, attorneys' fees or other charges
that could accrue as a result of foreclosure or sale of the Collateral. In any
contest Grantor shall defend itself and Lender and shall satisfy any final
adverse judgment before enforcement against the Collateral. Grantor shall name
Lender as an additional obliges under any surety bond furnished in the contest
proceedings.

Compliance With Governmental Requirements. Grantor shall comply promptly with
all laws, ordinances, rules and regulations of all governmental authorities, now
or hereafter in effect, applicable to the ownership, production, disposition, or
use of the Collateral. Grantor may contest in good faith any such law, ordinance
or regulation and withhold compliance during any proceeding, including
appropriate appeals, so long as Lender's interest in the Collateral, in Lender's
opinion, is not jeopardized.

Hazardous Substances. Grantor represents and warrants that the Collateral never
has been, and never will be so long as this Agreement remains a lien on the
Collateral, used for the generation, manufacture, storage, transportation,
treatment, disposal, release or threatened release of any hazardous waste or
substance, as those terms are defined in the Comprehensive Environmental
Response, Compensation, and Liability Act of 1980, as amended, 42 U.S.C. Section
9601, et seq. ("CERCLA"), the Superfund Amendments and Reauthorization Act of
1986, Pub. L. No. 9~99 ("SARA"), the Hazardous Materials Transportation Act, 49
U.S.C. Section 1801, et seq., the Resource Conservation and Recovery Act, 42
U.S.C.. Section 6901, of seq., or other applicable state or Federal laws, rules,
or regulations adopted pursuant to any of the foregoing. The terms "hazardous
waste" and "hazardous substance" shall also include, without limitation,
petroleum and petroleum by-products or any fraction thereof and asbestos. The
representations and warranties contained herein are based on Grantor's due
diligence in investigating the Collateral for hazardous wastes and substances.
Grantor hereby (a) releases and waives any future claims against Lender for
indemnity or contribution in the event Grantor becomes liable for cleanup or
other costs under any such laws, and (b) agrees to indemnify and hold harmless
Lender against any and all claims and losses resulting from a breach of this
provision of this Agreement. This obligation to indemnify shall survive the
payment

Maintenance of Casualty Insurance. Grantor shall procure and maintain all risks
insurance, including without limitation fire, theft and liability coverage
together with such other insurance as Lender may require with respect to the
Collateral, in form, amounts, coverages and basis reasonably acceptable to
Lender and issued by a company or companies reasonably acceptable to Lender.
Grantor, upon request of Lender, will deliver to Lender from time to time the
policies or certificates of insurance in form satisfactory to Lender, including
stipulations that coverages will not be cancelled or diminished without at least
ten (10) days' prior written notice to Lender and not including any disclaimer
of the insurer's liability for failure to give such a notice. Each insurance
policy also shall include an endorsement providing that coverage in favor of
Lender will not be impaired in any way by any act, omission or default of
Grantor or any other person. In connection with all policies covering assets in
which Lender holds or is offered a security interest, Grantor will provide
Lender with such loss payable or other endorsements as Lender may require. If
Grantor at any time fails to obtain or maintain any insurance as required under
this Agreement, Lender

<PAGE>


may (but shall not be obligated to) obtain such insurance as Lender deems
appropriate, including if it so chooses "single interest insurance," which will
cover only Lender's interest in the Collateral.

Application of Insurance Proceeds. Grantor shall promptly notify Lender of any
loss or damage to the Collateral. Lender may make proof of loss if Grantor tails
to do so within fifteen (15) days of the casualty. All proceeds of any insurance
on the Collateral, including accrued proceeds thereon, shall be held by Lender
as part of the Collateral. It Lender consents to repair or replacement of the
damaged or destroyed Collateral, Lender shall, upon satisfactory proof of
expenditure, pay or reimburse Grantor from the proceeds for the reasonable cost
of repair or restoration. If Lender does not consent to repair or replacement of
the Collateral, Lender shall retain a sufficient amount of the proceeds to pay
all of the Indebtedness, and shall pay the balance to Grantor. Any proceeds
which have not been disbursed within six (6) months after their receipt and
which Grantor has not committed to the repair or restoration of the Collateral
shall be used to prepay the Indebtedness.

Insurance Reserves. Lender may require Grantor to maintain with Lender reserves
for payment of insurance premiums, which reserves shall be created by monthly
payments from Grantor of a sum estimated by Lender to be sufficient to produce,
at least fifteen (15) days before the premium due date, amounts at least equal
to the insurance premiums to be paid. It fifteen (15) days before payment is
due, the reserve funds are insufficient, Grantor shall upon demand pay any
deficiency to Lender. The reserve funds shall be held by Lender as a general
deposit and shall constitute a non-interest-bearing account which Lender may
satisfy by payment of the insurance premiums required to be paid by Grantor as
they become due. Lender does not hold the reserve funds in trust for Grantor,
and Lender is not the agent of Grantor for payment of the insurance premiums
required to be paid by Grantor. The responsibility for the payment of premiums
shall remain Grantor's sole responsibility.

Insurance Reports. Grantor, upon request of Lender, shall furnish to Lender
reports on each existing policy of insurance showing such information as Lender
may reasonably request including the following: (a) the name of the insurer; (b)
the risks insured; (c) the amount of the policy; (d) the property insured; (e)
the then current value on the basis of which insurance has been obtained and the
manner of determining that value; and (f) the expiration date of the policy. In
addition, Grantor shall upon request by Lender (however not more often than
annually) have an independent appraiser satisfactory to Lender determine, as
applicable, the cash value or replacement cost of the Collateral.

GRANTOR'S RIGHT TO POSSESSION AND TO COLLECT ACCOUNTS. Until default and except
as otherwise provided below with respect to accounts, Grantor may have
possession of the tangible personal property and beneficial use of all the
Collateral and may use it in any lawful manner not inconsistent with this
Agreement or the Related Documents, provided that Grantor's right to possession
and beneficial use shall not apply to any Collateral where possession of the
Collateral by Lender is required by law to perfect Lender's security interest in
such Collateral. Until otherwise notified by Lender, Grantor may collect any of
the Collateral consisting of accounts. At any time and even though no Event of
Default exists, Lender may exercise its rights to collect the accounts and to
notify account debtors to make payments directly to Lender for application to
the Indebtedness. It Lender at any time has possession of any Collateral,
whether before or after an Event of Default, Lender shall be deemed to have
exercised reasonable care in the custody and preservation of the Collateral if
Lender takes such action for that purpose as Grantor shall request or as Lender,
in Lender's sole discretion, shall deem appropriate under the circumstances, but
failure to honor any request by Grantor shall not of itself be deemed to be a
failure to exercise reasonable care. Lender shall not be required to take any
steps necessary to preserve any rights in the Collateral against prior parties,
nor to protect, preserve or maintain any security interest given to secure the
Indebtedness.

EXPENDITURES BY LENDER. If not discharged or paid when due, Lender may (but
shall not be obligated to) discharge or pay any amounts required to be
discharged or paid by Grantor under this Agreement, including without limitation
all taxes, liens, security interests, encumbrances, and other claims, at any
time levied or placed on the Collateral. Lender also may (but shall not be
obligated to) pay all costs for insuring, maintaining and preserving the
Collateral. All such expenditures incurred or paid by Lender

<PAGE>


for such purposes will then bear interest at the rate charged under the Note
from the date incurred or paid by Lender to the date of repayment by Grantor.
All such expenses shall become a part of the Indebtedness and, at Lender's
option, will (a) be payable on demand, (b) be added to the balance of the Note
and be apportioned among and be payable with any installment payments to become
due during either (i) the term of any applicable insurance policy or (ii) the
remaining term of the Note, or (c) be treated as a balloon payment which will be
due and payable at the Note's maturity. This Agreement also will secure payment
of these amounts. Such right shall be in addition to all other rights and
remedies to which Lender may be entitled upon the occurrence of an Event of
Default.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default
under this Agreement:

Default on Indebtedness. Failure of Grantor to make any payment when due on the
Indebtedness.

Other Defaults. Failure of Grantor to comply with or to perform any other term,
obligation, covenant or condition contained in this Agreement or in any of the
Related Documents or in any other agreement between Lender and Grantor.

False Statements. Any warranty, representation or statement made or furnished to
Lender by or on behalf of Grantor under this Agreement, the Note or the Related
Documents is false or misleading in any material respect, either now or at the
time made or furnished.

Defective Collateralization. This Agreement or any of the Related Documents
ceases to be in full force and effect (including failure of any collateral
documents to create a valid and perfected security interest or lien) at any time
and for any reason.

Insolvency. The dissolution or termination of Grantor's existence as a going
business, the insolvency of Grantor, the appointment of a receiver for any part
of Grantor's property, any assignment for the benefit of creditors, any type of
creditor workout, or the commencement of any proceeding under any bankruptcy or
insolvency laws by or against Grantor.

Creditor or Forfeiture Proceedings. Commencement of foreclosure or forfeiture
proceedings, whether by judicial proceeding, self-help, repossession or any
other method, by any creditor of Grantor or by any governmental agency against
the Collateral or any other collateral securing the Indebtedness. This includes
a garnishment of any of Grantor's deposit accounts with Lender. However, this
Event of Default shall not apply if there is a good faith dispute by Grantor as
to the validity or reasonableness of the claim which is the basis of the
creditor or forfeiture proceeding and if Grantor gives Lender written notice of
the creditor or forfeiture proceeding and deposits with Lender monies or a
surety bond for the creditor or forfeiture proceeding, in an amount determined
by Lender, in its sole discretion, as being an adequate reserve or bond for the
dispute.

Events Affecting Guarantor. Any of the preceding events occurs with respect to
any Guarantor of any of the indebtedness or such Guarantor dies or becomes
incompetent. Lender, at its option, may, but shall not be required to, permit
the Guarantor's estate to assume unconditionally the obligations arising under
the guaranty in a manner satisfactory to Lender, and, in doing so, cure the
Event of Default.

Adverse Change. A material adverse change occurs in Grantor's financial
condition, or Lender believes the prospect of payment or performance of the
Indebtedness is impaired.

Insecurity. Lender, in good faith, deems itself insecure.

Right to Cure. If any default, other than a Default on Indebtedness, is curable
and if Grantor has not been given a prior notice of a breach of the same
provision of this Agreement, it may be cured (and no Event of Default will have
occurred) if Grantor, after Lender sends written notice demanding cure of such
default, (a) cures the default within fifteen (15) days; or lb), if the cure
requires more than fifteen (15) days,

<PAGE>


immediately initiates steps which Lender deems in Lender's sole discretion to be
sufficient to cure the default and thereafter continues and completes all
reasonable and necessary steps sufficient to produce compliance as soon as
reasonably practical.

RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under this
Agreement, at any time thereafter, Lender shall have all the rights of a secured
party under the Minnesota Uniform Commercial Code. In addition and without
limitation, Lender may exercise any one or more of the following rights and
remedies:

Accelerate Indebtedness. Lender may declare the entire Indebtedness, including
any prepayment penalty which Grantor would be required to pay, immediately due
and payable, without notice.

Assemble Collateral. Lender may require Grantor to deliver to Lender all or any
portion of the Collateral and any and all certificates of title and other
documents relating to the Collateral. Lender may require Grantor to assemble the
Collateral and make it available to Lender at a place to be designated by
Lender. Lender also shall have full power to enter upon the property of Grantor
to take possession of and remove the Collateral. If the Collateral contains
other goods not covered by this Agreement at the time of repossession, Grantor
agrees Lender may take such other goods, provided that Lender makes reasonable
efforts to return them to Grantor after repossession.

Sell the Collateral. Lender shall have full power to sell, lease, transfer, or
otherwise deal with the Collateral or proceeds thereof in its own name or that
of Grantor. Lender may sell the Collateral at public auction or private sale.
Unless the Collateral threatens to decline speedily in value or is of a type
customarily sold on a recognized market, Lender will give Grantor reasonable
notice of the time after which any private sale or any other intended
disposition of the Collateral is to be made. The requirements of reasonable
notice shall be met if such notice is given at least ten (10) days before the
time of the sale or disposition. All expenses relating to the disposition of the
Collateral, including without limitation the expenses of retaking, holding,
insuring, preparing for sale and selling the Collateral, shall become a part of
the Indebtedness secured by this Agreement and shall be payable on demand, with
interest at the Note rate from date of expenditure until repaid.

Appoint Receiver. To the extent permitted by applicable law, Lender shall have
the following rights and remedies regarding the appointment of a receiver: (a)
Lender may have a receiver appointed as a matter of right, (b) the receiver may
be an employee of Lender and may serve without bond, and (c) all tees of the
receiver and his or her attorney shall become part of the Indebtedness secured
by this Agreement and shall be payable on demand, with interest at the Note rate
from date of expenditure until repaid.

Collect Revenues. Apply Accounts. Lender, either itself or through a receiver,
may collect the payments, rents, income, and revenues from the Collateral.
Lender may at any time in its discretion transfer any Collateral into its own
name or that of its nominee and receive the payments, rents, income, and
revenues therefrom and hold the same as security for the Indebtedness or apply
it to payment of the Indebtedness in such order of preference as Lender may
determine. insofar as the Collateral consists of accounts, general intangibles,
insurance policies, instruments, chapel paper, chases in action, or similar
property, Lender may demand, collect, receipt for, settle, compromise, adjust,
sue for, foreclose, or realize on the Collateral as Lender may determine,
whether or not Indebtedness or Collateral is then due. For these purposes,
Lender may, on behalf of and in the name of Grantor, receive, open and dispose
of mail addressed to Grantor; change any address to which mail and payments are
to be sent; and endorse notes, checks, drabs, money orders, documents of title,
instruments and items pertaining to payment, shipment, or storage of any
Collateral. To facilitate collection, Lender may notify account debtors and
obligers on any Collateral to make payments directly to Lender.

Obtain Deficiency. If Lender chooses to sell any or all of the Collateral,
Lender may obtain a judgment against Grantor for any deficiency remaining on the
Indebtedness due to Lender after application of all

<PAGE>


amounts received from the exercise of the rights provided in this Agreement.
Grantor shall be liable for a deficiency even it the transaction described in
this subsection is a sale of accounts or chapel paper.

Other Rights and Remedies. Lender shall have all the rights and remedies of a
secured creditor under the provisions of the Uniform Commercial Code, as may be
amended from time to time. In addition, Lender shall have and may exercise any
or all other rights and remedies it may have available at law, in equity, or
otherwise.

Cumulative Remedies. All of Lender's rights and remedies, whether evidenced by
this Agreement or the Related Documents or by any other writing, shall be
cumulative and may be exercised singularly or concurrently. Election by Lender
to pursue any remedy shall not exclude pursuit of any other remedy, and an
election to make expenditures or to take action to perform an obligation of
Grantor under this Agreement, after Grantor's failure to perform, shall not
affect Lender's right to declare a default and to exercise its remedies.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a pad of
this Agreement:

the Collateral, this Agreement shall be binding upon and inure to the benefit of
the parties, their successors and assigns.

Waiver. Lender shall not be deemed to have waived any rights under this
Agreement unless such waiver is given in writing and signed by Lender. No delay
or omission on the part of Lender in exercising any right shall operate as a
waiver of such right or any other right. A waiver by Lender of a provision of
this Agreement shall not prejudice or constitute a waiver of Lender's right
otherwise to demand strict compliance with that provision or any other provision
of this Agreement. No prior waiver by Lender, nor any course of dealing between
Lender and Grantor, shall constitute a waiver of any of Lender's rights or of
any of Grantor's obligations as to any future transactions. Whenever the consent
of Lender is required under this Agreement, the granting of such consent by
Lender in any instance shall not constitute continuing consent to subsequent
instances where such consent is required and in all cases such consent may be
granted or withheld in the sole discretion of Lender.

GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS COMMERCIAL SECURITY
AGREEMENT, AND GRANTOR AGREES TO ITS TERMS. THIS AGREEMENT IS DATED MAY 15,
1998.

GRANTOR:
ORPHAN MEDICAL, INC.
By:
    -----------------------------
JOHN H. BULLION, CEO



                                                                   EXHIBIT 10.48


                              ORPHAN MEDICAL, INC.

                            STOCK PURCHASE AGREEMENT


         Agreement, made and entered into as of the 23rd day of July, 1998,
between Orphan Medical, Inc., a Minnesota corporation (the "Company"), and each
of the persons listed on Schedule 1 to this agreement (the "Investors").

         For good and valuable consideration, the receipt and adequacy of which
are hereby acknowledged, the Company and the Investors agree as follows:

         1. Authorization of Securities. The Company shall authorize, issue and
sell an aggregate of 7,500 shares of senior convertible preferred stock, par
value $0.01 per share, which shall be issued pursuant to and shall be entitled
to such other preferences, rights and benefits as are set forth in the capital
stock provisions of the Company's Certificate of Designation, which shall be in
the form of the attached Exhibit A. On or before the Initial Closing Date (as
defined in Section 3), the Company shall cause its Articles of Incorporation to
be amended so that they will contain provisions identical to Exhibit A. As used
in this agreement, the term "Preferred Shares" shall mean the shares of senior
convertible preferred stock to be sold pursuant to this agreement, including any
shares issued pursuant to the option described in Section 2.2 hereof, and all
shares of senior convertible preferred stock issued in exchange or substitution
therefor.

         2. Sale and Purchase of Preferred Shares.

                  2.1 Subject to the terms and conditions hereof, the Company
agrees to sell to each Investor, and each Investor severally agrees to purchase
from the Company on the Initial Closing Date, the number of Preferred Shares set
forth opposite its name on Schedule 1 at a purchase price of One Thousand
Dollars ($1,000) per share.

                  2.2 The Investors that purchased Preferred Shares on the
Initial Closing Date have an option to purchase, and, to the extent exercised,
the Company shall be obliged to sell to the Investors, up to an additional 4,500
Preferred Shares, subject to the limitations and procedures set forth in this
Section 2.2. Such Preferred Shares shall be sold on the same terms and
conditions as the securities being sold on the Initial Closing Date.
Notwithstanding the foregoing, if the Conversion Price (as defined in the
Certificate of Designation attached hereto as Exhibit A) is less than the last
sale price of the Company's Common Stock on the last trading day prior to the
Initial Closing Date, then the number of Preferred Shares issued on the
Supplemental Closing Date (as defined in Section 3) shall be reduced as
necessary so that the maximum number of shares of common stock, $.01 par value
per share, of the Company (the "Common Stock") issuable upon (a) conversion of
all the Preferred Shares sold by the Company pursuant to this agreement
(including Preferred Shares issued on both the Initial Closing Date and the
Supplemental Closing Date), and (b) conversion of the maximum number of
Preferred Shares that could be issued by the Company as dividends on the
Preferred Shares (in each case assuming the Preferred Shares are converted at
the Conversion Price determined as of the Supplemental Closing Date) (the
"Conversion Shares") shall be no greater than 1,250,000 (the "Maximum Conversion
Shares"). The Company shall deliver to the Investors on the date which is 90
days following the Initial Closing Date (or as soon as practicable thereafter
but in no event later than five business days following the ninetieth day after
the Initial Closing Date) written notice of the maximum aggregate number of
Preferred Shares the Investors may purchase on the Supplemental Closing Date (as
defined in Section 3), a calculation of the Maximum Conversion Shares, and a
calculation of the Conversion Price. No later than three business days after the
delivery of the Company's written notice, each Investor shall deliver to the
Company written notice of the number of Preferred Shares, if any, it shall
purchase on the Supplemental Closing Date (the "Option Notice").

<PAGE>


         3. Closing. The closing of the transactions contemplated by the first
paragraph of Section 2 of this agreement shall take place at the offices of
Dorsey & Whitney LLP, 220 South Sixth Street, Minneapolis, Minnesota 55402, at
10:00 A.M., Minneapolis time, on July __, 1998 (the "Initial Closing Date") or
at such other place or different time or day as may be mutually acceptable to
the Investors and the Company. The supplemental closing shall take place at such
time and place as may be selected jointly by the Company and the Investors,
which in any event shall be on or before the fifth business day after delivery
of the Option Notice by the Investors to the Company (the "Supplemental Closing
Date").

         At each closing, the Company will deliver to each Investor a
certificate, dated such closing date, representing the Preferred Shares
purchased by such Investor on such closing date, registered in its name as
stated on Schedule 1 (or in the name of its nominee if it so specifies to the
Company at least 48 hours prior to such closing date) against payment to the
Company of the purchase price of Preferred Shares being purchased by such
Investor, which payment shall be made by wire transfer of immediately available
funds.

         4. Representations and Warranties by the Company. In order to induce
each Investor to enter into this agreement and to purchase the number of
Preferred Shares set forth after its name on Schedule 1, the Company hereby
represents and warrants to each Investor that, except as disclosed in the
attached Exhibit B:

                  4.1 Organization, Standing, etc. The Company is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Minnesota, and has the requisite corporate power and authority to own
its properties and to carry on its business as it is now being conducted. The
Company has the requisite corporate power and authority to issue the Preferred
Shares and the Conversion Shares and to otherwise perform its obligations under
this agreement.

                  4.2 Governing Instruments. The copies of the Articles of
Incorporation and bylaws of the Company which have been delivered to legal
counsel for the Investors prior to the execution of this agreement are true and
complete copies of the duly and legally adopted Articles of Incorporation and
bylaws of the Company in effect as of the date of this agreement.

                  4.3 Subsidiaries, Etc. The Company does not have any direct or
indirect ownership interest in any corporation, partnership, joint venture,
association or other business enterprise (a "Subsidiary"). If any entity is
listed on Exhibit B and the Company owns a controlling interest in such entity,
the representations and warranties set forth in this Article 4 are being hereby
restated with respect to such entity (modified as appropriate to the nature of
such entity).

                  4.4 Qualification. The Company is duly qualified, licensed or
domesticated as a foreign corporation in good standing in each jurisdiction
wherein the nature of its activities or the properties owned or leased by it
makes such qualification, licensing or domestication necessary and in which
failure to so qualify or be licensed or domesticated would have a material
adverse impact upon its business.

                  4.5 Financial Statements. Attached to this agreement as
Exhibit C are (a) a balance sheet, as at December 31, 1997 for the Company,
together with the related statements of income and retained earnings and changes
in financial position for the fiscal year then ended which balance sheet and
related statements have been audited by Ernst & Young LLP and (b) a balance
sheet, as at June 30, 1998 for the Company, together with the related statement
of income and changes in financial position for the six (6)-month period then
ended. Such financial statements (i) are in accordance with the books and
records of the Company, (ii) present fairly the financial condition of the
Company at the balance sheets dates and the results of its operations for the

generally accepted accounting principles applied on a basis consistent with

Without limiting the generality of the foregoing, the balance sheets or notes
thereto disclose all of the debts, liabilities and obligations of any nature
(whether absolute, accrued or contingent and whether due or to become due) of
the Company at December 31, 1997, and June 30, 1998, which, individually or in
the aggregate, are material and which in accordance with generally accepted
accounting principles would be required to be disclosed in such balance sheets,
and include appropriate reserves for all taxes and other liabilities accrued as
of such dates but not yet payable.

                  4.6 Tax Returns and Audits. All required federal, state and
local tax returns or appropriate extension requests of the Company have been
filed, and all federal, state and local taxes required to be paid with respect
to such returns have been paid or due provision for the payment thereof has been
made. The Company is not delinquent in the payment of any such tax or in the
payment of any assessment or governmental charge. The Company has not received
notice of any tax deficiency proposed or assessed against it, and it has not
executed any waiver of any statute of limitations on the assessment or
collection of any tax. None of the Company's tax returns has been audited by
governmental authorities. The Company does not have any tax liabilities except
those incurred in the ordinary course of business since March 31, 1998.

this Agreement and the Investors shall have received satisfactory evidence of
such consents; provided, however, that the Company shall not attempt to obtain
shareholder approval of such transactions based on the Company's belief that the
Nasdaq Marketplace Rules do not require shareholder approval.

                  6.8 No Material Adverse Effect. Since March 31, 1998, no
event, change or effect shall have occurred that is materially adverse to the
consolidated financial condition, business, results of operations, cash flows or
prospects of the Company or that materially impairs the ability of the Company
to perform or the Investor to enforce the obligations of the Company under this
agreement.

                  6.9 Certificate of Designation. On or prior to the Initial

(i) on or before the Initial Closing Date and Supplemental Closing Date, as

                  6.11 Injunctions, Restraining Order or Adverse Litigation. No
order, judgment or decree of any court, arbitral tribunal, administrative agency
or other governmental or regulatory authority or agency shall purport to enjoin
or restrain the Investors from acquiring the Preferred Shares on the Initial
Closing Date or the Supplemental Closing date, as applicable.

                  6.12 Proceedings and Documents. All corporate and other
proceedings and actions taken in connection with the transactions contemplated
hereby and all certificates, opinions, agreements, instruments and documents

Price; or

         (b) the Company receives written confirmation from Nasdaq that no
shareholder approval is required to effectuate the anti-dilution provisions set
forth in Section 8(c) of the Certificate of Designation if such provisions would
be triggered as a result of such issuance; or

         (c) shareholder approval for such issuance is obtained.

                  7.2 Financial and Business Information. The Company will
maintain, and cause each of its Subsidiaries to maintain, a system of accounting
established in accordance with sound business practices to permit preparation of
financial statements in conformity with GAAP. The Company during the term of
this agreement will, and will cause its Subsidiaries to, deliver to the
Investors:

fairly present the financial condition of Company and its Subsidiaries as the
dates indicated and the results of its operations and its cash flows for the

adjustments (it being understood by the parties hereto that the delivery to the
Investor of the Company's quarterly report on Form 10-Q will satisfy the

         (c) As soon as practicable and in any event within 30 days after the
end of each month, the internal financial statements of the Company and its
Subsidiaries for such month (other than the months referred to in Section 7.2(a)
and Section 7.2(b) above) and certified by the chief executive officer or the
chief financial officer of the Company that such statements were prepared in
accordance with the Company's accounting policies, consistently applied for the

obtaining knowledge of any condition or event that constitutes a violation or
default or potential event of default under any indebtedness of the Company or

notice or taken any other action with respect to a claimed event of default or
potential event of default, notice of any such event; and

         (e) Within a reasonable time, such other information about the
property, financial condition and operations of the Company and its Subsidiaries
as the Investors may from time to time reasonably request.

                  7.3 Notice of Certain Events. The Company will, and will cause
its Subsidiaries to, promptly give notice in writing to each Investor of any
litigation or proceeding before any court or administrative body involving the
Company or any Subsidiary which, if determined adversely to the Company or such

business, operations, financial condition, prospects or results of operation of
the Company.

         8. Conversion of Preferred Shares.

                  8.1 Conversion of Preferred Shares.

         (a) Any holder of any Preferred Shares may, at its option, from and
after the occurrence of such events as are set forth in the relevant provisions
of the Company's Articles of Incorporation, convert such Preferred Shares, or
any part thereof, into Conversion Shares at the Conversion Price and upon the
terms and conditions and subject to the adjustments set forth in the Company's
Articles of Incorporation.

         (b) Each Preferred Share shall be automatically converted into
Conversion Shares on the terms and conditions set forth in the Company's
Articles of Incorporation.

                  8.2 Stock Fully Paid; Reservation of Shares. The Company
covenants and agrees that all Conversion Shares that may be issued upon the
exercise of the conversion privilege referred to in Section 8.1 will, upon
issuance in accordance with the terms of the Company's Articles of
Incorporation, be fully paid and nonassessable and free from all taxes, liens
and charges (except for taxes, if any, upon the income of the holder and
applicable transfer taxes) with respect to the issue thereof, and that the
issuance thereof shall not give rise to any preemptive rights on the part of any
person. The Company further covenants and agrees that the Company will at all
times have authorized and reserved a sufficient number of its common shares for
the purpose of issuance upon the exercise of such conversion privilege.

                  8.3 Adjustment of Number of Shares and Conversion Price. The
number of common shares issuable upon conversion of Preferred Shares and the
Conversion Price with respect thereto shall be subject to adjustment from time
to time as set forth in the Company's Articles of Incorporation.

         9. Redemption of Preferred Shares. The Company may redeem and
repurchase Preferred Shares from the holders thereof, and will redeem and
repurchase the Preferred Shares from the holders thereof, at the times and upon
the terms and conditions set forth in the Company's Articles of Incorporation.

         10. Registration Rights. The Company acknowledges and agrees that the
Investors shall have the registration rights set forth on Exhibit F.

         11. Right of First Refusal.

         (a) In the event (and on each occasion) that, after the date hereof,
the Company shall propose to issue equity securities, any rights, warrants or
options to purchase equity securities or any securities convertible into equity
securities ("New Securities"), other than a Permitted Issuance (as defined
below), the Company shall give the Investors written notice (an "Offer Notice")
of the Company's proposal,

<PAGE>


describing the material terms upon which the Company has proposed to issue the
New Securities. The Investors shall have fifteen (15) business days from the
date on which the Company shall give the written Offer Notice to agree to
purchase such New Securities, in whole or in part, upon the terms specified in
the Offer Notice, and in compliance with paragraph (c) of this Section 11, by
giving written notice to the Company and stating therein the quantity of New
Securities to be purchased by such Investors. If, in connection with such a
proposed issuance of New Securities, an Investor shall for any reason fail or
refuse to give such written notice to the Company within such period of fifteen
(15) business days, such Investor shall, for all purposes of this Section 11, be
deemed to have refused (in that particular instance only) to purchase any of
such New Securities and to have waived (in that particular instance only) all
rights of such Investor under this Section 11 to purchase any of such New
Securities. If an Investor gives written notice of its intent to purchase such
New Securities an Investor shall close upon such purchase within twenty (20)
days after the date of the delivery of the Investor's notice to the Company
electing to purchase New Securities.

         (b) "Permitted Issuance" shall mean (i) the issuance or sale of (A)
Common Stock upon the exercise of any options to acquire Common Stock that are
outstanding on the First Issuance Date (as defined in Section 7 of the
Certificate of Designation) (as such number of shares is proportionately
adjusted for subsequent stock splits, combinations of shares and stock dividends
affecting the Common Stock), in each case pursuant to the terms thereof as in
effect on the First Issuance Date, (B) shares of Common Stock that may be issued
after the First Issuance Date to Chronimed, Inc. pursuant to the terms of the
Termination Agreement between the Company and Chronimed, Inc., and (C) stock
options and shares of Common Stock issuable upon exercise of such options
granted to employees and directors of the Company and its Subsidiaries pursuant
to the terms of stock option plans approved by the Company's Board of Directors
if such options are excersisable at the market price on the date of grant;
provided that the aggregate number of shares of Common Stock issued, or
issuable, pursuant to this clause (i) shall not exceed two million shares, (ii)
the issuance of Common Stock upon the exercise of the Warrants, (iii) the
issuance of Common Stock upon the conversion or exchange of the Preferred Stock
and (iv) the issuance of securities pursuant to any public offering of the
Company's securities registered under the Securities Act.

         (c) In the event that the Investor shall fail or refuse to exercise in
full its preemptive rights within said fifteen (15) day period, the Company
shall have sixty (60) days thereafter (the "Sale Period") to sell the quantity
of New Securities which the Investors did not agree to purchase pursuant to
paragraph (c) of this Section 11, upon the terms specified in the Company's
Offer Notice to the Investors. In the event the Company has not sold the New
Securities within the Sale Period, the Company will not thereafter issue or sell
any New Securities without first offering such securities to the Investors in
the manner provided by the foregoing provisions of this Section 11.

         (d) The Company will not, at any time after the effective date of this
agreement, enter into any agreement or contract (whether written or oral) which
is inconsistent in any respect with the right of first refusal granted by the
Company to the Investors pursuant to this Section 11.

         12. Restriction on Transfer of Shares.

                  12.1 Restrictions. The Preferred Shares and Conversion Shares
are only transferable pursuant to (a) a public offering registered under the
Securities Act or (b) pursuant to an exemption from the registration
requirements of the Securities Act and applicable state securities or blue sky
laws.

                  12.2 Legend. Each certificate representing Preferred Shares
shall be endorsed with the following legend:

<PAGE>


"The shares represented by this certificate may not be transferred without (i)
an exemption from the registration requirements under the Federal Securities Act
of 1933, as amended, and all applicable state securities laws or (ii) such
registration."

Upon the conversion of any Preferred Shares, unless the Company receives an
opinion of counsel satisfactory to the Company to the effect that a transfer of
the Conversion Shares may be made without registration or further restriction on
transfer, or unless such Conversion Shares are being disposed of pursuant to a
registration under the Securities Act, the same legend shall be endorsed on the
certificate evidencing such Conversion Shares.

                  12.3 Removal of Legend. Any legend endorsed on a certificate
evidencing a security pursuant to Section 12.2 hereof shall be removed, and the
Company shall issue a certificate without such legend to the holder of such
security, if such security is being disposed of pursuant to a registration under
the Securities Act or pursuant to Rule 144 or any similar rule then in effect or
if such holder provides the Company with an opinion of counsel satisfactory to
the Company to the effect that a transfer of such security may be made without
registration. In addition, if the holder of such security delivers to the
Company an opinion of such counsel to the effect that no subsequent transfer of
such security will require registration under the Securities Act, the Company
will promptly upon such contemplated transfer deliver new certificates
evidencing such security that do not bear the legend set forth in Section 12.2.

         13. Miscellaneous.

                  13.1 No Waivers; Cumulative Remedies. No failure or delay on
the part of the Investors, or any other holder of any Purchased Shares in
exercising any right, power or remedy hereunder or thereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any such right,
power or remedy preclude any other or further exercise thereof or the exercise
of any other right, power or remedy hereunder or thereunder. The remedies herein
provided are cumulative and not exclusive of any remedies provided by law.

                  13.2 Amendments; Waiver and Consents. This agreement may be
amended or modified, and the obligations of the Company and the rights of the
holders of Purchased Shares under this agreement may be waived only by the
written consent of holders of a majority of the Conversion Shares issuable upon
conversion and the Conversion Shares that have been issued as a result of
conversion and that have not been resold in a public offering or transferred
pursuant to Rule 144 promulgated under the Securities Act. Any waiver or consent
may be given subject to satisfaction of conditions stated therein and any waiver
or consent shall be effective only in the specific instance and for the specific
purpose for which given.

                  13.3 Changes, Waivers, Etc. Neither this agreement nor any
provision hereof may be changed, waived, discharged or terminated orally, but
only by a statement in writing signed by the party against which enforcement of
the change, waiver, discharge or termination is sought, except to the extent
provided in Section 13.2.

                  13.4 Expenses. Whether or not the transactions contemplated
hereby shall be consummated, the Company agrees to pay promptly (a) the fees,
expenses and disbursements of counsel to the Investors in connection with the
negotiation, preparation, execution, delivery and administration of this
agreement, the Certificate of Designation and the transactions contemplated
hereby and thereby, not to exceed $75,000, and any consents, amendments, waivers
or other modifications hereto or thereto and any other documents or matters
requested by the Company; and (b) all costs and expenses, including reasonable
attorneys' fees and costs of settlement, incurred by the Investors in enforcing
any obligations of or in collecting any payments due from the Company hereunder
or as a holder of Preferred Shares or Conversion Shares by reason of any breach
or default by the Company or in connection with any 

<PAGE>


refinancing or restructuring of the arrangements provided hereunder in the
nature of a "work-out" or pursuant to any insolvency or bankruptcy proceedings.

                  13.5 Notices. All notices, requests, consents and other
communications required or permitted hereunder shall be in writing and shall be
delivered, or mailed first-class postage prepaid, registered or certified mail,

                  (a) if to any holder of any Purchased Shares addressed to such
holder at its address as shown on the books of the Company, or at such other
address as such holder may specify by written notice to the Company, or

                  (b) if to the Company at 13911 Ridgedale Drive, Minnetonka,
Minnesota 55305. Attention: President; or at such other address as the Company
may specify by written notice to the Investors.

                  13.6 Assignment.

                  (a) This agreement and all of the provisions hereof will be
binding upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

                  (b) The Investors may freely assign their rights, interests
and obligations under Section 2.2 to their affiliates. The Investors may not
assign their rights, interests and obligations set forth in Section 2.2 to any
non-affiliate without the consent of the Company, which may not be unreasonably
withheld.

                  (c) The Investors may freely assign their rights, interests
and obligations attached to the Preferred Shares and the Conversion Shares, as
applicable, upon transfer of such Shares in accordance with Section 5.1.

                  (d) Neither this agreement nor any of the rights, interests or
obligations hereunder may be assigned by the Company without the prior written
consent of the Investors hereto.

                  13.7 Severability. Whenever possible, each provision of this
agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this agreement is held to be prohibited
by or invalid under applicable law, such provision will be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of such provision or the remaining provisions of this agreement.

                  13.8 Complete Agreement. This agreement and other exhibits and
schedules hereto contain the complete agreement between the parties and
supersede any prior understandings, agreements or representations by or between
the parties, written or oral, which may have related to the subject matter
hereof in any way.

                  13.9 Governing Law. The internal law, without regard to
conflicts of laws principles, of the State of New York will govern all questions

EXHIBIT F

REGISTRATION RIGHTS PROVISIONS


         Capitalized terms used herein have the meanings set forth in Section 8.

                  1. Demand Registration.

                  (a) At any time and from time to time, a Majority-in-Interest
of the Holders shall have the right, by written notice (the "Demand Notice")
given to the Company, to request the Company to file with the SEC a Registration
Statement with respect to all or any portion of the Registrable Shares held by
such Holders and/or the Registrable Shares issuable upon conversion of Shares
held by such Holders, as designated by such Holders. Upon receipt of any such
Demand Notice, the Company shall promptly, but in no event more than five days
after receipt thereof, notify all other Holders of the receipt of such Demand
Notice and, subject to the limitations set forth below, shall include in the
proposed registration all Registrable Shares with respect to which the Company
has received written requests for inclusion therein within 20 days after
delivery of the Company's notice. In connection with any Demand Registration in
which more than one holder of securities participates, in the event that such
Demand Registration involves an underwritten offering and the managing
underwriter or underwriters participating in such offering advise in writing the
Holders of Registrable Shares and the holders of other securities to be included
in such offering that the total number of Registrable Shares and other
securities to be included in such offering exceeds the amount that can be sold
in (or during the time of) such offering without delaying or jeopardizing the
success of such offering (including the price per share of the Registrable
Shares and other securities to be sold), then the amount of Registrable Shares
and other securities to be offered for the account of such Holders shall be
reduced as follows: first, pro rata on the basis of the number of securities
other than Registrable Shares and Warrant Shares requested to be registered by
the holders of such securities; and second, pro rata on the basis of the number
of Warrants Shares and Registrable Shares requested to be registered by the
holders of such securities. The Holders as a group shall be entitled to two
Demand Registrations pursuant to this Section 1; provided, that any Demand
Registration that does not become effective or is not maintained for the time
period required in accordance with Section 1(c) shall not count as one of such
Demand Registrations, except as set forth in Section 1(f); provided, further,
that if the Demanding Holders have requested inclusion in such Demand
Registration and 75% or less of the securities so requested to be included have
been included, the Holders as a group shall be entitled to an additional Demand
Registration hereunder on the same terms and conditions as would have applied to
the Holders had such earlier Demand Registration not been made. Anything herein
to the contrary notwithstanding, the Company shall not be required to effect a
Demand Registration pursuant to this Section 1 within a period of six (6) months
after the effective date of any other Demand Registration.

                  (b) The Company, within 45 days of the date on which the
Company receives a Demand Notice given by Holders in accordance with Section
1(a) hereof, shall file with the SEC, and the Company shall thereafter use its
best efforts to cause to be declared effective within 90 days following the date
the Company receives such Demand Notice, a Registration Statement on the
appropriate form for the registration and sale, in accordance with the intended
method or methods of distribution requested by the Holders, of the total number
of Registrable Shares specified by the Holders in such Demand Notice (a "Demand
Registration").

                  (c) The Company shall use commercially reasonable efforts to
keep each Registration Statement filed pursuant to this Section 1 continuously
effective and usable for the resale of the Registrable Shares covered thereby
for a period of 270 days from the date on which the SEC declares such
Registration Statement effective, as such period may be extended pursuant to
this Section 1, or in the case of a Shelf Registration, for a period of two
years from the date that the SEC declares such "shelf" Registration Statement
effective, or if shorter, until all the Registrable Shares covered by such
Registration Statement have been sold pursuant to such Registration Statement.

<PAGE>


                  (d) The Company shall be entitled to postpone the filing of
any Registration Statement otherwise required to be prepared and filed by the
Company pursuant to this Section 1, or suspend the use of any effective
Registration Statement under this Section 1, for a reasonable period of time
which shall be as short as practicable, but in any event not in excess of 60
days (a "Delay Period"), if the Company determines in good faith that the
registration and distribution of the Registrable Shares covered or to be covered
by such Registration Statement would materially interfere with any pending
material financing, acquisition or corporate reorganization or other material
corporate development involving the Company or any of its Subsidiaries or would
require premature disclosure thereof and promptly gives the Holders written
notice of such determination, containing a statement of the reasons for such
postponement and an approximation of the period of the anticipated delay;
provided, however, that (i) the aggregate number of days included in all Delay
Periods during any consecutive 12 months shall not exceed the aggregate of (x)
180 days minus (y) the number of days occurring during all Interruption Periods
during such consecutive 12 months and (ii) a period of at least 60 days shall
elapse between the termination of any Delay Period or Interruption Period and
the commencement of the immediately succeeding Delay Period. If the Company
shall so postpone the filing of a Registration Statement, the Holders of
Registrable Shares to be registered shall have the right to withdraw the request
for registration by giving written notice to the Company from the Holders of a
majority of the Registrable Shares that were to be registered within 45 days
after receipt of the notice of postponement or, if earlier, the termination of
such Delay Period. The time period for which the Company is required to maintain
the effectiveness of any Registration Statement shall be extended by the
aggregate number of days of all Delay Periods and all Interruption Periods
occurring during such Registration and any extension thereof is hereinafter
referred to as the "Effectiveness Period". The Company shall not be entitled to
initiate a Delay Period unless it shall (A) to the extent permitted by
agreements with other security holders of the Company, concurrently prohibit
sales by such other security holders under registration statements covering
securities held by such other security holders and (B) in accordance with the
Company's policies from time to time in effect, forbid purchases and sales in
the open market by senior executives of the Company.

                  (e) The Demanding Holders may, at any time prior to the
effective date of the Registration Statement relating to a Demand Registration,
revoke such request by providing a written notice to the Company revoking such
request. In the event of such revocation, the Demanding Holders shall reimburse
the Company for all of its out-of-pocket expenses incurred in connection with
the preparation, filing and processing of the Registration Statement, unless (i)
there has been a material adverse change in the business, assets, properties,
condition (financial or other), results of operations or prospects of the
Company and its Subsidiaries, since the time of the Demand Notice, (ii) such
revocation was based on the Company's failure to comply in any material respect
with its obligations hereunder or (iii) the Demanding Holders choose to count
the Demand Registration as one of the Demand Registrations to which the
Demanding Holders are entitled pursuant to the penultimate sentence of Section
1(a).

                  2. Piggyback Registration.

                  (a) Right to Piggyback. If at any time the Company proposes to
file a registration statement under the Securities Act with respect to a public
offering of securities of the same type as the Registrable Shares for its own
account (other than a registration statement (i) on Form S-8 or any successor
form thereto, (ii) filed solely in connection with a dividend reinvestment plan
or employee benefit plan covering officers or directors of the Company or its
Affiliates or (iii) on Form S-4 or any successor form thereto, in connection
with a merger, acquisition or similar corporate transaction) or for the account
of any holder of securities of the same type as the Registrable Shares, then the
Company shall give written notice of such proposed filing to the Holders at
least 30 days before the anticipated filing date. Such notice shall offer the
Holders the opportunity to register such number of Registrable Shares as they
may request (a "Piggyback Registration"). Subject to Section 2(b) hereof, the
Company shall include in each such Piggyback Registration all Registrable Shares
with respect to which the Company has received written requests for inclusion
therein within 20 days after notice has been given to the Holders. Each Holder
shall

<PAGE>


be permitted to withdraw all or any portion of the Registrable Shares of such
Holder from a Piggyback Registration at any time prior to the effective date of
such Piggyback Registration.

                  (b) Priority on Piggyback Registrations. The Company shall
permit the Holders to include all such Registrable Shares on the same terms and
conditions as any similar securities, if any, of the Company included therein.
Notwithstanding the foregoing, if the Company or the managing underwriter or
underwriters participating in such offering advise the Holders in writing that
the total number of securities requested to be included in such Piggyback
Registration exceeds the number which can be sold in (or during the time of)
such offering without delaying or jeopardizing the success of the offering
(including the price per share of the securities to be sold), then the number of
securities to be offered for the account of the Holders and other holders of
securities who requested to have securities included in such Registration
Statement shall be reduced (to zero if necessary) pro rata on the basis of the
number or amount of Common Stock (or the equivalent) requested to be registered
by each such Holder or holder participating in such offering.

                  (c) Right To Abandon. Nothing in this Section 2 shall create
any liability on the part of the Company to the Holders if the Company in its
sole discretion should decide not to file a registration statement proposed to
be filed pursuant to Section 2(a) hereof or to withdraw such registration
statement subsequent to its filing, regardless of any action whatsoever that a
Holder may have taken, whether as a result of the issuance by the Company of any
notice hereunder or otherwise.

                  3. Registration Procedures. In connection with the
registration obligations of the Company pursuant to and in accordance with
Sections 1 and 2 hereof (and subject to Sections 1 and 2 hereof), the Company
shall use commercially reasonable efforts to effect such registration to permit
the sale of such Registrable Shares in accordance with the intended method or
methods of disposition thereof, and pursuant thereto the Company shall as
expeditiously as possible (but subject to Sections 1 and 2 hereof):

                  (a) prepare and file with the SEC a Registration Statement for
the sale of the Registrable Shares on any form for which the Company then
qualifies or which counsel for the Company shall deem appropriate in accordance
with such Holders' intended method or methods of distribution thereof, subject

Registration Statement to become effective and remain effective as provided
herein;

                  (b) prepare and file with the SEC such amendments (including
post-effective amendments) to such Registration Statement, and such supplements
to the related Prospectus, as may be required by the applicable rules,
regulations or instructions under the Securities Act during the applicable
period in accordance with the intended methods of disposition specified by the
Holders of the Registrable Shares covered by such Registration Statement, make
generally available earnings statements satisfying the provisions of Section
11(a) of the Securities Act (provided that the Company shall be deemed to have
complied with this clause if it has complied with Rule 158 under the Securities
Act), and cause the related Prospectus as so supplemented to be filed pursuant
to Rule 424 under the Securities Act; provided, however, that before filing a
Registration Statement or Prospectus, or any amendments or supplements thereto
(other than reports required to be filed by it under the Exchange Act), the
Company shall furnish to the Holders of Registrable Shares covered by such
Registration Statement and their counsel for review and comment, copies of all
documents proposed to be filed;

                  (c) notify the Holders of any Registrable Shares covered by
such Registration Statement promptly and (if requested) confirm such notice in
writing, (i) when a Prospectus or any Prospectus supplement or post-effective
amendment has been filed, and, with respect to such Registration Statement or
any post-effective amendment, when the same has become effective, (ii) of any
request by the SEC for amendments or supplements to such Registration Statement
or the related Prospectus or for additional information regarding such Holders,
(iii) of the issuance by the SEC of any stop order suspending the effectiveness
of such Registration Statement or the initiation of any proceedings for that

<PAGE>


purpose, (iv) of the receipt by the Company of any notification with respect to
the suspension of the qualification or exemption from qualification of any of
the Registrable Shares for sale in any jurisdiction or the initiation or
threatening of any proceeding for such purpose, and (v) of the happening of any
event that requires the making of any changes in such Registration Statement,
Prospectus or documents incorporated or deemed to be incorporated therein by
reference so that they will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading;

                  (d) use commercially reasonable efforts to obtain the
withdrawal of any order suspending the effectiveness of such Registration
Statement, or the lifting of any suspension of the qualification or exemption
from qualification of any Registrable Shares for sale in any jurisdiction in the
United States;

                  (e) furnish to the Holder of any Registrable Shares covered by
such Registration Statement, each counsel for such Holders and each managing
underwriter, if any, without charge, one conformed copy of such Registration

all reports incorporated or deemed to be incorporated therein by reference; and
deliver, without charge, such number of copies of the preliminary prospectus,
any amended preliminary prospectus, each final Prospectus and any post-effective

to facilitate the disposition of the Registrable Shares of such Holder covered
by such Registration Statement in conformity with the requirements of the
Securities Act;

                  (f) prior to any public offering of Registrable Shares covered
by such Registration Statement, use commercially reasonable efforts to register
or qualify such Registrable Shares for offer and sale under the securities or
Blue Sky laws of such jurisdictions as the Holders of such Registrable Shares
shall reasonably request in writing; provided, however, that the Company shall
in no event be required to qualify generally to do business as a foreign
corporation or as a dealer in any jurisdiction where it is not at the time so
qualified or to execute or file a general consent to service of process in any
such jurisdiction where it has not theretofore done so or to take any action
that would subject it to general service of process or taxation in any such
jurisdiction where it is not then subject;

                  (g) upon the occurrence of any event contemplated by paragraph
3(c)(v) above, prepare a supplement or post-effective amendment to such
Registration Statement or the related Prospectus or any document incorporated or
deemed to be incorporated therein by reference and file any other required
document so that, as thereafter delivered to the purchaser of the Registrable
Shares being sold thereunder (including upon the termination of any Delay
Period), such Prospectus will not contain an untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading;

                  (h) use its best efforts to cause all Registrable Shares
covered by such Registration Statement to be listed on each securities exchange,
if any, on which similar securities issued by the Company are then listed or
quoted and, if no such securities are so listed, to be listed on the Nasdaq
Stock Market and, if listed on the Nasdaq Stock Market, use its best efforts to
secure designation of all such Registrable Shares covered by such registration
statement as "NASDAQ Securities" within the meaning of Rule 11Aa2-1 promulgated
under the Exchange Act or, failing that, to secure Nasdaq Stock Market
authorization for such Registrable Shares;

                  (i) on or before the effective date of such Registration
Statement, provide the transfer agent of the Company for the Registrable Shares
with printed certificates for the Registrable Shares covered by such
Registration Statement, which are in a form eligible for deposit with The
Depository Trust Company;

<PAGE>


                  (j) make available for inspection by any Holder of Registrable
Shares included in such Registration Statement, any underwriter participating in
any offering pursuant to such Registration Statement, and any attorney,
accountant or other agent retained by any such Holder or underwriter
(collectively, the "Inspectors"), all financial and other records and other
information, pertinent corporate documents and properties of any of the Company
and its Subsidiaries and affiliates (collectively, the "Records"), as shall be
reasonably necessary to enable them to exercise their due diligence
responsibilities; provided, however, that the Records that the Company
determines, in good faith, to be confidential and which it notifies the
Inspectors in writing are confidential shall not be disclosed to any Inspector
unless such Inspector signs a confidentiality agreement reasonably satisfactory
to the Company (which shall permit the disclosure of such Records in such
Registration Statement or the related Prospectus if necessary to avoid or
correct a material misstatement in or material omission from such Registration
Statement or Prospectus) or either (i) the disclosure of such Records is
necessary to avoid or correct a misstatement or omission in such Registration
Statement or (ii) the release of such Records is ordered pursuant to a subpoena
or other order from a court of competent jurisdiction; provided, further, that
(A) any decision regarding the disclosure of information pursuant to subclause
(i) shall be made only after consultation with counsel for the applicable
Inspectors and the Company and (B) with respect to any release of Records
pursuant to subclause (ii), each Holder of Registrable Shares agrees that it
shall, promptly after learning that disclosure of such Records is sought in a
court having jurisdiction, give notice to the Company so that the Company, at
the Company's expense, may undertake appropriate action to prevent disclosure of
such Records; and

                  (k) if such offering is an underwritten offering, enter into
such agreements (including an underwriting agreement in form, scope and
substance as is customary in underwritten offerings) and take all such other
appropriate and reasonable actions requested by the Holders of a majority of the
Registrable Shares being sold in connection therewith (including those
reasonably requested by the managing underwriters) in order to expedite or
facilitate the disposition of such Registrable Shares, and in such connection,
(i) use commercially reasonable efforts to obtain opinions of counsel to the
Company and updates thereof (which counsel and opinions (in form, scope and
substance) shall be reasonably satisfactory to the managing underwriters and
counsel to the Holders of the Registrable Shares being sold), addressed to each
selling Holder of Registrable Shares covered by such Registration Statement and
each of the underwriters as to the matters customarily covered in opinions
requested in underwritten offerings and such other matters as may be reasonably
requested by such counsel and underwriters, (ii) use commercially reasonable
efforts to obtain "cold comfort" letters and updates thereof from the
independent certified public accountants of the Company (and, if necessary, any
other independent certified public accountants of any subsidiary of the Company
or of any business acquired by the Company for which financial statements and
financial data are, or are required to be, included in the Registration
Statement), addressed to each selling holder of Registrable Shares covered by
the Registration Statement (unless such accountants shall be prohibited from so
addressing such letters by applicable standards of the accounting profession)
and each of the underwriters, such letters to be in customary form and covering
matters of the type customarily covered in "cold comfort" letters in connection
with underwritten offerings, (iii) if requested and if an underwriting agreement
is entered into, provide indemnification provisions and procedures reasonably
requested by such underwriters. The above shall be done at each closing under
such underwriting or similar agreement, or as and to the extent required
thereunder. The Company may require each Holder of Registrable Shares covered by
a Registration Statement to furnish, within a period not less than 20 days from
the date of receipt of such request, such information regarding such Holder and
such Holder's intended method of disposition of such Registrable Shares as it
may from time to time reasonably request in writing. If any such information is
not furnished within such period, the Company may exclude such Holder's
Registrable Shares from such Registration Statement. Each Holder of Registrable
Shares covered by a Registration Statement agrees that, upon receipt of any
notice from the Company of the happening of any event of the kind described in
Section 3(c)(ii), 3(c)(iii), 3(c)(iv) or 3(c)(v) hereof, that such Holder shall
forthwith discontinue disposition of any Registrable Shares covered by such
Registration Statement or the related Prospectus until receipt of the copies of
the supplemented or amended Prospectus contemplated by Section 3(g) hereof, or
until such Holder is advised in writing by the Company that the use of the
applicable Prospectus may be resumed, and has received copies of any amended or

<PAGE>


supplemented Prospectus or any additional or supplemental filings which are
incorporated, or deemed to be incorporated, by reference in such Prospectus
(such period during which disposition is discontinued being an "Interruption
Period") and, if requested by the Company, the Holder shall deliver to the
Company (at the expense of the Company) all copies then in its possession, other
than permanent file copies then in such holder's possession, of the Prospectus
covering such Registrable Shares at the time of receipt of such request. Each
Holder of Registrable Shares covered by a Registration Statement further agrees
not to utilize any material other than the applicable current preliminary
prospectus or Prospectus in connection with the offering of such Registrable
Shares.

                  4. Registration Expenses. Whether or not any Registration
Statement is filed or becomes effective but subject to Section 1(e), the Company
shall pay all costs, fees and expenses incident to the Company's performance of
or compliance with this Agreement, including (i) all registration and filing
fees, including National Association of Securities Dealers filing fees, (ii) all
fees and expenses of compliance with securities or Blue Sky laws, including
reasonable fees and disbursements of counsel in connection therewith, (iii)
printing expenses (including expenses of printing certificates for Registrable
Shares and of printing prospectuses if the printing of prospectuses is requested
by the Holders or the managing underwriter, if any), (iv) messenger, telephone
and delivery expenses, (v) fees and disbursements of counsel for the Company,
(vi) fees and disbursements of all independent certified public accountants of
the Company (including expenses of any "cold comfort" letters required in
connection with this Agreement) and all other persons retained by the Company in
connection with such Registration Statement, (vii) fees and disbursements of one
counsel, other than the Company's counsel, representing all of the Holders of
Registrable Shares being registered, selected by a Majority-in-Interest of
Holders of the Registrable Shares being registered, or in the event of a Demand
Registration, selected by the Demanding Holders and reasonably satisfactory to a
Majority-in-Interest of Holders of the Registrable Shares being registered other
than the Demanding Holders, [DISCUSS] (viii) fees and disbursements of
underwriters customarily paid by the issuers or sellers of securities and (ix)
all other costs, fees and expenses incident to the Company's performance or
compliance with this Agreement. Notwithstanding the foregoing, any discounts,
commissions or brokers' fees or fees of similar securities industry
professionals and any transfer taxes relating to the disposition of the
Registrable Shares by a Holder, will be payable by such Holder and the Company
will have no obligation to pay any such amounts.

                  5. Underwriting Requirements.

                  (a) Subject to Section 5(b) hereof, the Demanding Holders
shall have the right, by written notice, to require that any Demand Registration
provide for an underwritten offering.

                  (b) In the case of any underwritten offering pursuant to a
Demand Registration, the Demanding Holders shall select the institution or
institutions that shall manage or lead such offering, which institution or
institutions shall be reasonably satisfactory to the Company. In the case of any
underwritten offering pursuant to a Piggyback Registration, the Company shall
select the institution or institutions that shall manage or lead such offering.
No Holder shall be entitled to participate in an underwritten offering unless
and until such Holder has entered into an underwriting or other agreement with
such institution or institutions for such offering in such form as the Company
and such institution or institutions shall determine and such form is on terms
customary for such an offering.

                  (c) Each Holder participating in a Registration shall promptly
supply in writing such information as the Demanding Holders, the Company or the
underwriters reasonably request.

                  6. Indemnification.

                  (a) Indemnification by the Company. The Company shall
indemnify and hold harmless, to the full extent permitted by law, each Holder of
Registrable Shares whose Registrable Shares are covered by a Registration
Statement or Prospectus, the officers, directors and agents and employees of
each

<PAGE>


of them, each Person who controls each such Holder (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) and the
officers, directors, agents and employees of each such controlling Person, to
the fullest extent lawful, from and against any and all losses, claims, damages,
liabilities, judgment, costs (including, without limitation, costs of
investigation, preparation and reasonable attorneys' fees) and expenses
(collectively, "Losses"), as incurred, arising out of or based upon any untrue
or alleged untrue statement of a material fact contained in such Registration
Statement or Prospectus or in any amendment or supplement thereto or in any
preliminary prospectus, or arising out of or based upon any omission or alleged
omission of a material fact required to be stated therein or necessary to make
the statements therein not misleading, except insofar as the same are based upon
information furnished in writing to the Company by or on behalf of such Holder
expressly for use therein.

                  (b) Indemnification by Holder of Registrable Shares. In
connection with any Registration Statement in which a Holder is participating,
such Holder shall indemnify and hold harmless, to the full extent permitted by
law, the Company, its directors, officers, agents or employees, each Person who
controls the Company (within the meaning of Section 15 of the Securities Act and
Section 20 of the Exchange Act) and the directors, officers, agents or employees
of such controlling Persons, from and against all Losses arising out of or based
upon any untrue or alleged untrue statement of a material fact contained in such
Registration Statement or the related Prospectus or any amendment or supplement
thereto, or any preliminary prospectus, or arising out of or based upon any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, to the extent, but only
to the extent, that such untrue or alleged untrue statement or omission or
alleged omission is based upon any information furnished in writing by or on
behalf of such Holder to the Company expressly for use in such Registration
Statement or Prospectus. Each Holder's indemnity obligations under this Section
6 shall be limited to the total sales proceeds (net of all underwriting
discounts and commissions) actually received by such Holder in connection with
the applicable offering.

                  (c) Conduct of Indemnification Proceedings. If any Person
shall be entitled to indemnity hereunder (an "indemnified party"), such
indemnified party shall give prompt notice to the party from which such
indemnity is sought (the "indemnifying party") of any claim or of the
commencement of any proceeding with respect to which such indemnified party
seeks indemnification or contribution pursuant hereto; provided, however, that
the delay or failure to so notify the indemnifying party shall not relieve the
indemnifying party from any obligation or liability except to the extent that
the indemnifying party has been prejudiced by such delay or failure. The
indemnifying party shall have the right, exercisable by giving written notice to
an indemnified party promptly after the receipt of written notice from such
indemnified party of such claim or proceeding, to assume, at the indemnifying
party's expense, the defense of any such claim or proceeding, with counsel
reasonably satisfactory to such indemnified party; provided, however, that (i)
an indemnified party shall have the right to employ separate counsel in any such
claim or proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless: (1) the indemnifying party agrees to pay such fees and expenses; (2) the
indemnifying party fails promptly to assume the defense of such claim or
proceeding or fails to employ counsel reasonably satisfactory to such
indemnified party; or (3) the named parties to any proceeding (including
impleaded parties) include both such indemnified party and the indemnifying
party, and such indemnified party shall have been advised by counsel that there
may be one or more legal defenses available to it that are inconsistent with
those available to the indemnifying party or that a conflict of interest is
likely to exist among such indemnified party and any other indemnified parties
(in which case the indemnifying party shall not have the right to assume the
defense of such action on behalf of such indemnified party); and (ii) subject to
clause (3) above, the indemnifying party shall not, in connection with any one
such claim or proceeding or separate but substantially similar or related claims
or proceedings in the same jurisdiction, arising out of the same general
allegations or circumstances, be liable for the fees and expenses of more than
one firm of attorneys (together with appropriate local counsel) at any time for
all of the indemnified parties, or for fees and expenses that are not
reasonable. Whether or not such defense is assumed by the indemnifying party,
such indemnified party shall not be subject to any liability for any settlement
made without its consent. The indemnifying party shall not consent to entry of
any judgment or enter into any settlement unless (i) there is no finding or
admission of any violation of any

<PAGE>


rights of any person and no effect on any other claims that may be made against
the indemnified party, (ii) the sole relief provided is monetary damages that
are paid in full by the indemnifying party and (iii) such judgment or settlement
includes as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party of a release, in form and substance
reasonably satisfactory to the indemnified party, from all liability in respect
of such claim or litigation for which such indemnified party would be entitled
to indemnification hereunder.

                  (d) Contribution. If the indemnification provided for in this
Section 6 is unavailable to an indemnified party in respect of any Losses (other
than in accordance with its terms), then each applicable indemnifying party, in
lieu of indemnifying such indemnified party, shall contribute to the amount paid
or payable by such indemnified party as a result of such Losses, in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party, on the one hand, and such indemnified party, on the other hand, in
connection with the actions, statements or omissions that resulted in such
Losses as well as any other relevant equitable considerations. The relative
fault of such indemnifying party, on the one hand, and indemnified party, on the
other hand, shall be determined by reference to, among other things, whether any
action in question, including any untrue statement of a material fact or
omission or alleged omission to state a material fact, has been taken by, or
relates to information supplied by, such indemnifying party or indemnified
party, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent any such action, statement or omission. The
amount paid or payable by a party as a result of any Losses shall be deemed to
include any legal or other fees or expenses incurred by such party in connection
with any investigation or proceeding. The parties hereto agree that it would not
be just and equitable if contribution pursuant to this Section 6(d) were
determined by pro rata allocation or by any other method of allocation that does
not take account of the equitable considerations referred to in the two
immediately preceding sentences. Notwithstanding the provisions of this Section
6(d), an indemnifying party that is a Holder shall not be required to contribute
any amount which is in excess of the amount by which the total proceeds (net of
all underwriting discounts and commissions) received by such Holder from the
sale of the Registrable Shares sold by such Holder in the applicable offering
exceed the amount of any damages that such indemnifying party has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation.

                  7. Granting of Registration Rights. The Company shall not
grant any registration rights inconsistent with those granted hereunder or that
give any security holder a position with respect to cut-backs that are superior
to the Holders' position as granted herein, without the consent of a
Majority-in-Interest of the Holders of the Registrable Shares (voting together
as a single class).

                              ORPHAN MEDICAL, INC.

    CAUTIONARY STATEMENTS FOR PURPOSES OF THE "SAFE HARBOR" PROVISIONS OF THE
                PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995


The Private Securities Litigation Reform Act of 1995 provides a "safe harbor"
for forward-looking statements to encourage companies to provide prospective
information without fear of litigation so long as statements are identified as
forward-looking and are accompanied by meaningful cautionary statements
identifying important factors that could cause actual results to differ
materially from those projected. The Company desires to take advantage of these
"safe harbor" provisions and is filing this Exhibit 99 in order to do so.
Accordingly, when used in this Annual Report on Form 10-K and in future filings
by the Company with the Securities and Exchange Commission, quarterly reports,
press releases and in oral statements made with the approval of an authorized
executive officer, the words or phrases "will likely result", "look for", "may
result", "will continue", "is anticipated", "expect", "project", or similar
expressions are intended to identify "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995. Such statements
are subject to certain risks and uncertainties that could cause actual results
to differ materially from historical earnings and those presently anticipated or
projected. The Company hereby cautions readers that the following important
factors, among others, could affect the Company's financial performance and
could cause the Company's actual results for future periods to differ materially
from any forward-looking statements made by or on behalf of the Company.


LACK OF REVENUES AND PROFITABLE OPERATIONS; UNCERTAINTY OF FUTURE FINANCIAL
RESULTS.
The Company has been unprofitable since its inception in January 1993 and had an
accumulated deficit of $30,265,691 as of June 30, 1998. From inception through
June 30, 1998, the Company reported Elliotts B Solution, Cystadane, Antizol-Vet,
and Antizol sales of $3,160,120 and gross profit on such sales of $2,460,811,
which is not sufficient to sustain future product development or business
growth. The Company expects operating losses to continue into 1999 because gross
profit from its five approved products, including Sucraid, is not expected to
offset additional spending required to complete the development plans for
Busulfex and Xyrem, and for additional sales and marketing spending for the new
product introductions. The amount of these losses may vary significantly from
year-to-year and quarter-to-quarter and will depend on, among other factors, the
timing of product development and regulatory approval. There can be no assurance
that the Company will ever generate material product revenues or achieve
profitability.

DEVELOPMENT STAGE COMPANY.
The Company is in the development stage and its operations and the development
of its proposed products are subject to all of the risks inherent in the
establishment of a new business enterprise, including reliance on key personnel,
the lack of fully-developed products, insufficient capital, a competitive
environment characterized by numerous well-established and well-capitalized
competitors, expected operating losses into 1999, a market subject to extensive
regulatory oversight, and reliance on outside contractors for the manufacture
and distribution of its proposed products. The likelihood of the success of the
Company must be considered in light of the problems, expenses and delays
frequently encountered in connection with the development of new pharmaceutical
products or medical products and the competitive and regulatory environment in
which the Company operates.

FUTURE CAPITAL REQUIREMENTS; NO ASSURANCE FUTURE CAPITAL WILL BE AVAILABLE.
The Company's cash, cash equivalents, and short-term investments as of June 30,
1998 plus the $7.1 million in net cash proceeds from the July 23, 1998 sale of a
private placement are expected to be sufficient to fund the Company's operations
through 1999. However, should the Company realize any material reduction in
product revenues and/or a delay in the FDA approval and market launch of
Busulfex, the Company may require additional funding to fully implement its
development plan for Xyrem. Adequate funds for the Company's operations, whether
from financial markets or from other sources, may not be available when needed
on terms attractive to the Company, or at all. Lack of funding could cause the
Company to delay, scale back or eliminate some or all of its products currently
under development, including acquisition and licensing programs, or prevent the
commercial introduction of some or all of its products altogether.

<PAGE>


DEPENDENCE ON LICENSE AND ACQUISITION STRATEGY.
The Company has adopted a license and acquisition strategy to build its product
portfolio. The Company's strategy for growth is dependent upon its continued
ability to identify and acquire new pharmaceutical products targeted at niche
markets within selected strategic therapeutic market segments ("STMS"). Because
the Company does not engage in proprietary research and development of new
pharmaceutical products, it must rely upon the willingness of others to sell or
license pharmaceutical product opportunities to the Company. Other companies,
including those with substantially greater resources, are competing with the
Company to acquire such products. There can be no assurance that the Company
will be able to acquire rights to additional products on acceptable terms, if at
all. The failure of the Company to acquire or license new pharmaceutical
products within a selected STMS or to promote and market commercially successful
products within an existing STMS could have a material adverse effect on the
Company's business and its prospects.

The Company has contractual production rights to certain compounds through
various license agreements. These agreements are generally terminable by the
licensor for cause upon short notice or in the event the Company is insolvent or
bankrupt, does not apply minimum resources and efforts to develop the compound
under license or does not achieve certain minimum royalty payments. There can be
no assurance that the agreements will not be so terminated and, if terminated,
that the Company will be able to enter into similar agreements on terms as
favorable to the Company as those contained in its existing license agreements.

FOREIGN MARKETING ALLIANCES; NO ASSURANCE OF FOREIGN LICENSEES.
The Company's strategy for the exploitation of foreign markets for its products
is to enter into marketing alliances with multinational and foreign
pharmaceutical companies. From inception through June 30, 1998, the Company has
entered into distribution agreements to sell Cystadane in Australia and New
Zealand, and Antizol in Europe. Sales of Cystadane for Australia and New Zealand
have not been nor are they expected to be material. Distribution of Antizol in
Europe will initially be done on a "named patient" or "emergency use" basis
until full regulatory approval is obtained, and the Company does not expect such
"emergency use" distribution to result in material sales. Distribution of
Antizol in Europe through normal or the usual distribution channels will not
commence until the product has received marketing approval in each European
country into which the distributor expects to sell the product. The Company
typically receives upfront fees for entering into such arrangements and expects
to realize future benefits because the Company will be the exclusive supplier of
the product sold to the distributor in these foreign markets. However, there can
be no assurance that the Company will be able to negotiate additional alliances
for its other products on acceptable terms, if at all, or that such alliances
will be successful. The Company will be substantially dependent upon the
companies it has contracted with to date for the successful distribution of
Cystadane and Antizol outside the U.S. and, if these companies are unsuccessful
in their distribution efforts, it would be difficult for the Company to contract
with other distributors for these products within the licensed territories.

GOVERNMENT REGULATION; NEED FOR FDA AND OTHER REGULATORY APPROVALS.
Government regulation in the United States and abroad will be a significant
factor in the production, testing and marketing of the Company's current and
future products. Prior to marketing, each of the Company's products must undergo
an extensive regulatory approval process conducted by the United States Food and
Drug Administration (the "FDA") and by comparable agencies in other countries.
The approval process can take many years and require the expenditure of
substantial resources, and there can be no assurance that any product that the
Company may develop will be approved by the FDA or any foreign regulatory
authority in a timely manner, or at all. Generally, only a very small percentage
of newly discovered pharmaceutical compounds that enter pre-clinical development
are approved for sale. The Company will not be permitted to market any medicine
it may develop as a prescription product in any jurisdiction in which the
product does not receive regulatory approval. Once approved, the Division of
Drug Marketing, Advertising and Communication ("DDMAC"), the FDA's marketing
surveillance department within the Center for Drugs, must approve marketing
claims, which are the basis for a product's labeling, advertising and promotion.
There can be no assurance that the claims the Company is seeking will be
approved by DDMAC. The failure to obtain acceptable marketing claims on a
product from DDMAC could have a material adverse effect on the Company and its
prospects.

<PAGE>


The Company depends on external laboratories and medical institutions to conduct
its pre-clinical and clinical testing in compliance with clinical and laboratory
practices established by the FDA. The data obtained from pre-clinical and
clinical testing are subject to varying interpretations that could delay, limit
or prevent regulatory approval. In addition, delays or rejection may be
encountered based upon changes in FDA policy for drug approval during the period
of development and by the requirements for regulatory review of each submitted
New Drug Application ("NDA"). Moreover, even if the FDA approves a product, such
approval may entail commercially unacceptable limitations on the uses, or
"indications," for which a product may be marketed, and further studies may be
required to provide additional data on safety or effectiveness. The FDA also
requires post-marketing adverse event surveillance programs to monitor the
product's side effects.

An approved FDA product and the product's manufacturer are subject to continual
regulatory review and the later discovery of previously unknown problems with a
product or manufacturer may result in restrictions or sanctions on such products
or manufacturer, including the withdrawal of such product from the market. Most
changes in the manufacturing procedures for any of the Company's approved
products and any change in manufacturers will require the approval of the FDA
prior to their implementation. Obtaining the FDA's approval for a change in
manufacturing procedures or change in manufacturers could cause production
delays and loss of sales, which would have a material adverse effect the
Company's business and its prospects.

In certain countries, the sales price of a product must also be approved after
marketing approval is granted. No assurance can be given that satisfactory
prices can be obtained in foreign markets even if marketing approval is granted
by foreign regulatory authorities.

ORPHAN DRUG STATUS.
Under the Orphan Drug Act, the FDA may grant orphan drug designation to drugs
intended to treat a "rare disease or condition," which generally is a disease or
condition that affects populations of fewer than 200,000 people in the United
States. Orphan drug designation must be requested before submitting an NDA, and
after the FDA grants orphan drug designation, the generic identity of the
therapeutic agent and its potential orphan use are publicized by the FDA. Under
current law, orphan drug status is conferred upon the first company to receive
FDA approval to market the designated drug for the designated indication, which
also grants United States marketing exclusivity for a period of seven years
following approval by the NDA, subject to certain limitations. Orphan drug
designation does not convey any advantage in, or shorten the duration of, the
regulatory approval process. Moreover, although obtaining FDA approval to market
a product with orphan drug status can be advantageous, there can be no assurance
that the scope of protection or the level of marketing exclusivity that is
currently afforded by orphan drug status and marketing approval will remain in
effect in the future. Busulfex and Xyrem have orphan drug designation; while
Antizol, Elliotts B Solution, Cystadane, and Sucraid have orphan drug status.
There can be no assurance, however, that any product candidates will receive an
orphan drug designation or that any of the Company's products with such a
designation will be the first to be approved by the FDA for the designated
indication, thereby obtaining orphan drug status (i.e., marketing exclusivity).
Orphan drug designation does not prevent other manufacturers from attempting to
develop the same drug for the designated indication or from obtaining the
approval of an NDA for their drug prior to the approval of the Company's NDA. If
another sponsor's NDA for the same drug and the same indication is approved
first, that sponsor is entitled to exclusive marketing rights if that sponsor
has received orphan drug designation for its drug. In that case, the FDA would
refrain from approving an application by the Company to market its competing
product for seven years, subject to certain limitations. There can be no
assurance that competing products will not receive orphan drug designations and
FDA marketing approval before the Company's products.

NDA approval of a drug with an orphan drug designation does not prevent the FDA
from approving the same drug for a different indication, or a molecular
variation of the same drug for the same indication. Because doctors are not
restricted by the FDA from prescribing an approved drug for uses not approved by
the FDA, it is also possible that another company's drug could be prescribed for
indications for which the Company's product has received orphan drug designation
and NDA approval. Such prescribing of approved drugs for unapproved uses
(commonly referred to as "off label" use) could adversely affect the marketing
potential of products that have received orphan drug designation and NDA
approval. In addition, NDA approval of a drug with an orphan drug designation
does not provide any marketing exclusivity in foreign markets. The possible
amendment of the Orphan Drug Act by the

<PAGE>


United States Congress has been the subject of frequent discussion. Although no
significant changes to the Orphan Drug Act have been made for a number of years,
members of Congress have from time to time proposed legislation that would limit
the application of the Orphan Drug Act. There can be no assurance as to the
precise scope of protection that may be afforded by orphan drug designation and
marketing approval in the future or that the current level of exclusivity will
remain in effect.

RELIANCE ON PATENTS AND OTHER PROPRIETARY RIGHTS.
The pharmaceutical industry places considerable importance on obtaining patent
and trade secret protection for new technologies, products and processes. The
Company's success will depend, in part, on its ability to enjoy, obtain and
enforce protection for its products under United States and foreign patent laws
and other intellectual property laws, preserve the confidentiality of its trade
secrets and operate without infringing the proprietary rights of third parties.
The patent position of pharmaceutical firms is often highly uncertain and
generally involves complex legal and factual questions. At June 30, 1998,
Busulfex is the only product that the Company has under development for which
the use of or treatment methods licensed by the Company are covered by United
States patents. The Company evaluates the desirability of seeking patent or
other forms of protection for its products in foreign markets based on the
expected costs and relative benefits of attaining such protection. There can be
no assurance that any patents will be issued from any applications or that any
issued patents will afford adequate protection to the Company. Further, there
can be no assurance that any issued patents will not be challenged, invalidated,
infringed or circumvented or that any rights granted thereunder will provide
competitive advantages to the Company. Parties not affiliated with the Company
have obtained or may obtain United States or foreign patents or possess or may
possess proprietary rights relating to the Company's products. There can be no
assurance that patents now in existence or hereafter issued to others will not
adversely affect the development or commercialization of the Company's products
or that the Company's planned activities will not infringe patents owned by
others.

The Company could incur substantial costs in defending itself in infringement
suits brought against it or any of its licensors or in asserting any
infringement claims that the Company may have against others. The Company could
also incur substantial costs in connection with any suits relating to matters
for which the Company has agreed to indemnify its licensors or distributors. An
adverse outcome in any such litigation could have a material adverse effect on
the Company's business and prospects. In addition, the Company could be required
to obtain licenses under patents or other proprietary rights of third parties.
No assurance can be given that any such licenses would be made available on
terms acceptable to the Company, or at all. If the Company is required to, and
does not obtain any such required licenses, it could be prevented from, or
encounter delays in, developing, manufacturing or marketing one or more of its
products.

Busulfex and Xyrem are in the development stage. Even if the development of such
products is successful and marketing clearance from the FDA is obtained, there
can be no assurance that applicable patent coverage, if any, will not have
expired or will not expire shortly after such approval. Any such expiration
could have a material adverse effect on the sales and profitability of such
product. Further, some of the compounds the Company has developed or intends to
develop (Cystadane, Elliotts B Solution, Antizol, Antizol-Vet, Xyrem and
Sucraid) are believed to be in the public domain or not presently subject to
patent protection in the United States.

The Company also seeks to protect its proprietary information and technology in
part by confidentiality agreements and inventors' rights agreements with its
employees. There can be no assurance that these agreements will not be breached,
that the Company will have adequate remedies for any breach or that the
Company's trade secrets will not otherwise be disclosed to or discovered by its
competitors.

COMPETITION; RAPID TECHNOLOGICAL CHANGE.
Competition in the pharmaceutical industry is intense. Potential competitors in
the United States are numerous and include pharmaceutical, chemical and
biotechnology companies, most of which have substantially greater capital
resources, marketing experience, research and development staffs and facilities
than the Company. Although the Company seeks to limit potential sources of
competition by developing products that are eligible for orphan drug designation
and NDA approval or other forms of protection, there can be no assurance that
the Company's competitors will not succeed in developing similar technologies
and products more rapidly than the Company or

<PAGE>


that these competing technologies and products will not be more effective than
any of those that are being or will be developed by the Company.

The Company is aware of products being developed by potential competitors that
have received orphan drug designations for the same respective indications as
Busulfex and Xyrem. If these drugs are approved for marketing before the
Company's products, the Company would be required to obtain a license from these
entities before its own competing products could be marketed. There can be no
assurance that any required license would be available on commercially
acceptable terms, or at all.

The pharmaceutical industry has experienced rapid and significant technological
change. The Company expects that pharmaceutical technology will continue to
develop rapidly, and the Company's future success will depend, in large part, on
its ability to develop and maintain a competitive position. Technological
development by others may result in the Company's products becoming obsolete
before they are marketed or before the Company recovers a significant portion of
the development and commercialization expenses incurred with respect to such
products. In addition, alternative therapies or new medical treatments could
alter existing treatment regimes, and thereby reduce the need for one or more of
the Company's products, which would adversely affect the Company's business and
its prospects.

RISKS OF NEW PRODUCT DEVELOPMENT; MARKET UNCERTAINTY.
Only five of the Company's products have been approved for marketing by
regulatory authorities in the United States or elsewhere. Even if the balance of
the Company's products are approved for sale, there can be no assurance that
they will be commercially successful or that they will obtain the results
expected. The Company may encounter unanticipated problems relating to the
development, manufacturing, distribution and marketing of its products, some of
which may be beyond the Company's financial and technical capacity to solve. The
failure to adequately address any such problems could have a material adverse
effect on the Company's business and its prospects.

No drug development portfolio can be completely insulated from potential
failures, and it is likely that some products selected for development by the
Company will not produce the results expected during clinical studies, not
receive FDA approval or fail to generate product sales of an acceptable level.
The Company has terminated the development of eleven products from its portfolio
since inception: L-Cycloserine in 1994, Glucaric Acid in 1996, and nine products
in 1997. With respect to the nine products terminated in 1997, the Company took
this action in order to focus its development efforts on those products that fit
within three selected STMS: Antidote, Oncology Support, and Sleep Disorders. The
Company recorded a one-time charge of $780,000 in the third quarter of 1997 for
the estimated cost of winding down the development plans for nine development
products. In addition, the Company believes that several of the products
terminated in 1997 may have value to another pharmaceutical company and it will
seek to license or sell its rights relating to these products. The termination
of the development of any one or more of the Company's current products could
have a material adverse effect on the Company and its prospects.

Most orphan drugs have a potential United States market of less than $10 million
annually and many address annual markets of less than $1 million. There can be
no assurance that the Company's sales of its products will be profitable even if
accepted and used by patients and medical specialists.

DEPENDENCE UPON OTHERS FOR CLINICAL TESTING AND MANUFACTURING.
The Company does not have and does not intend to establish any internal product
testing, manufacturing or distribution capabilities. Accordingly, the Company
will be required to enter into arrangements with other companies for the
clinical testing, manufacture and distribution of its products. The inability of
the Company to retain third-parties for these purposes on acceptable terms could
adversely affect the Company's ability to develop and market its products. Any
failures by third-parties to adequately perform their responsibilities may delay
the submission of products for regulatory approval, impair the Company's ability
to deliver its products on a timely basis or otherwise impair the Company's
competitive position. In addition, the Company's dependence on third-parties for
the development, manufacture and distribution of its products may adversely
affect its potential profit margins and its ability to develop and deliver its
products on a timely basis. The manufacture of drugs can be an expensive, time
consuming and complex process and may require the use of materials with limited
availability or a

<PAGE>


dependence on sole suppliers. In addition, several of the Company's products
have not yet been manufactured in commercial quantities, and there can be no
assurance that such products can be so manufactured in a cost-effective manner.
Manufacturers of the Company's products will be subject to applicable good
manufacturing practices ("GMP") prescribed by the FDA or other rules and
regulations prescribed by foreign regulatory authorities. There can be no
assurance that the Company will be able to enter into or maintain relationships
either domestically or abroad with manufacturers whose facilities and procedures
comply or will continue to comply with GMP or applicable foreign requirements.
Should manufacturing agreements be entered into, the Company will be dependent
on such manufacturers for continued compliance with GMP and applicable foreign
standards. Failure by a manufacturer of the Company's products to comply with
GMP or applicable foreign requirements could result in significant time delays
or the inability of the Company to commercialize or continue to market a product
and could have a material adverse effect on the Company and its prospects. In
the United States, failure to comply with GMP or other applicable legal
requirements can lead to federal seizure of violative products, injunctive
actions brought by the federal government, and potential criminal and civil
liability on the part of a company and its officers and employees.

DEPENDENCE UPON OTHERS FOR DISTRIBUTION.
The Company has an exclusive agreement with Cardinal Health, Inc. ("Cardinal"),
whereby Cardinal, through its Specialty Companies, will provide a variety of
services to support the effective distribution of Orphan Medical's products.
Cardinal will provide integrated distribution and operations services to process
and support transactions between Orphan Medical and wholesalers, specialty
distributors, and direct customers; reimbursement management; patient assistance
and information hotline services; and specialty distribution and marketing
services to physician practices. Elliotts B Solution, Antizol, and Sucraid are
currently distributed by Cardinal, which also will distribute the Company's
proposed products should those products receive marketing clearance from the FDA
in the future. The Company will, therefore, be substantially dependent upon
Cardinal's ability to successfully distribute Elliotts B Solution, Antizol,
Sucraid and all of the Company's proposed products that receive marketing
clearance from the FDA.

Cystadane is currently distributed in the U.S. by Chronimed Inc. ("Chronimed"),
which distributes this product directly to patients through its mail order
pharmacy. The Company is substantially dependent upon Chronimed's ability to
successfully distribute Cystadane directly to patients in the U.S.

Antizol-Vet is currently distributed exclusively through W.A. Butler Company
("Butler"), the largest distributor of veterinary pharmaceuticals in the United
States. The Company is substantially dependent upon Butler's ability to
successfully distribute Antizol-Vet. The management of this product and reliance
on the sales efforts of a contract distributor has proven to be more difficult
than the Company originally expected and the Company is presently reviewing its
options with respect to the Antizol-Vet product, which could include the sale or
licensing of its rights to this product.

There can be no assurance that other distribution companies would be available
or continue to be available on commercially acceptable terms, if at all. The
loss of a distributor or failure to renew agreements with an existing
distributor could have a material adverse effect on the Company and its
prospects.

UNCERTAIN EXTENT OF PRICE FLEXIBILITY AND THIRD-PARTY REIMBURSEMENT.
The Company's ability to commercialize its products successfully will depend in
part on the price it may be able to charge for its products and on the extent to
which reimbursement for the cost of such products and related treatment will be
available from government health administration authorities, private health
insurers and other third-party payors. Government officials and private health
insurers are increasingly challenging the price of medical products and
services. Significant uncertainty exists as to the pricing flexibility suppliers
will have with respect to, and the reimbursement status of, newly approved
health care products.

In the United States, the Company expects that there will continue to be a
number of federal and state proposals to implement government control of pricing
and profitability of prescription pharmaceuticals. Cost controls, if mandated by
a government agency, could decrease the price the Company receives for its
products or products it may develop in the future and, by preventing the
recovery of development costs, which could be substantial, and an

<PAGE>


appropriate profit margin, could have a material adverse effect on the Company.
Furthermore, federal and state regulations govern or influence the reimbursement
to health care providers in connection with medical treatment of certain
patients. If any actions are taken by federal and/or state governments, such
actions could adversely affect the prospects for sales of the Company's
products. There can be no assurance that actions taken by federal and/or state
governments, if any, with regard to health care reform will not have a material
adverse effect on the Company and its prospects.

Certain third-party payors may attempt to further control costs by selecting
exclusive providers of their pharmaceutical products. If such arrangements were
made with competitors of the Company, such payors would not reimburse patients
for purchases of the Company's competing products. This lack of reimbursement
would diminish the market for the Company's products and could have a material
adverse effect on the Company and its prospects.

RISK OF PRODUCT RECALL
Product recalls may be issued at the discretion of the Company, the FDA, the
U.S. Federal Trade Commission, or other government agencies having regulatory
authority for product sales, and may occur due to disputed labeling claims,
manufacturing issues, quality defects, or other reasons. No assurance can be
given that product recalls will not occur. The Company does not carry any
insurance to cover the risk of a potential product recall. Any product recall
could have a material adverse effect on the Company and its prospects.

PRODUCT LIABILITY AND INSURANCE RISKS.
The testing and sale of human health care products by the Company entails an
inherent risk that product liability claims may be asserted against the Company.
As the Company expands the scope of its clinical testing, the Company will be
exposed to increasing potential liabilities. The pharmaceutical industry has
experienced increasing difficulty in maintaining product liability insurance
coverage at reasonable levels, and substantial increases in insurance premium
costs in many cases have rendered coverage economically impractical. The Company
currently carries product liability coverage in the aggregate amount of $10
million for all claims made in any policy year. Although to date the Company has
not been the subject of any product liability or other claims, there can be no
assurance that the Company will be able to maintain product liability insurance
on acceptable terms or that its insurance will provide adequate coverage against
potential claims. The successful assertion of any uninsured product liability or
other claim against the Company could have a material adverse effect on the
Company's business and prospects.

DEPENDENCE ON CERTAIN OFFICERS AND KEY MANAGEMENT PERSONNEL.
The Company's success will be largely dependent upon the efforts of its
executive officers and key management personnel. The loss of the services of an
executive officer or one or more key employees, or the inability of the Company
to attract and retain skilled management and marketing personnel in the future,
could have a material adverse effect on the Company and its prospects.

YEAR 2000 READINESS ISSUE.
The Company has assessed and continues to assess the impact of the so called
"Year 2000 Readiness Issue" on its reporting systems and operations. The Year
2000 Readiness Issue relates to the ability of computer hardware, software, and
firmware products to accurately process date/time data (including calculating,
comparing, and sequencing) from, into, and between the twentieth and
twenty-first centuries, and the years 1999 and 2000 and leap year calculations.
In addition, it relates to the ability to properly exchange time/date data
between such products. When the year 2000 occurs, systems that are not year 2000
compliant might recognize the year 2000 as the year 1900, or not at all. This
inability to recognize or properly treat the year 2000 may cause the Company's
systems, or the systems used by the Company's suppliers, distributors, customers
or regulatory agencies (i.e., FDA) to process critical financial and operational
information incorrectly, or not at all.

The Company's strategy is and has been to replace its older, inefficient systems
with current technology, which is both year 2000 compliant and more efficient.
In addition, the Company has purchased and implemented financial and operational
software upgrades that are year 2000 compliant. Because the Company has been
active in upgrading computer systems, including related operating and
application software, to provide for greater employee

<PAGE>


efficiency and customer responsiveness, direct expenses related to specific Year
2000 Readiness Issues should not be material to the Company's financial
statements. In addition, the Company has confirmed with its principal vendors
and distributors that they have implemented Year 2000 Readiness programs.
However, there can be no assurance that the systems of third parties on which
the Company currently relies or may rely on in the future will be year 2000
compliant, or that the failure of a third party's system due to the Year 2000
Readiness Issue would not have a material adverse effect on the Company and its
prospects.

RESTRICTIONS, COVENANTS AND RIGHTS RELATED TO SENIOR CONVERTIBLE PREFERRED STOCK
On July 23, 1998 (the "First Issuance Date"), the Company completed the sale to
UBS Capital II LLC ("UBS Capital") of a private placement of $7.5 million of
Senior Convertible Preferred Stock (the "Preferred Shares"). The private
placement agreement also gives UBS Capital the right to invest up to an
additional $4.5 million within 90 days of the First Issuance Date. In
conjunction with the issuance of the Preferred Shares, the Company agreed to
several restrictions and covenants, and granted certain voting and other rights
to the holders of the Preferred Shares, including but not limited to the
following:

      1.    The Company is restricted from issuing additional equity securities,
            including convertible debt instruments, warrants, and stock options,
            except for a "Permitted Issuances", which are limited to: (A) shares
            of Common Stock issued after the First Issuance Date to Chronimed,
            Inc. pursuant to the terms of the Termination Agreement between the
            Company and Chronimed, Inc., (B) shares of Common Stock issued upon
            exercise of stock options that are outstanding on the First Issuance
            Date, (C) stock options granted and shares of Common Stock issuable
            upon exercise of such options pursuant to the terms of stock option
            plans approved by the Company's Board of Directors; provided that
            the aggregate number of shares of Common Stock issued, or issuable,
            under (A), (B) and (C) shall not exceed two million shares, (D)
            Common Stock issued upon the exercise of currently outstanding
            warrants that, as of June 30, 1998, entitled holders to purchase an
            aggregate of 213,255 shares of Common Stock, (E) Common Stock issued
            upon the conversion of the Preferred Shares, and (F) securities
            issued pursuant to any public offering of the Company's securities
            registered under the Securities Act. In addition, the sale of any
            private placement of equity securities must be approved by a
            majority vote of the holders of the Preferred Shares and, if
            approved by the holders, UBS Capital has the right of first refusal
            with respect to the purchase or sale of any such securities.

      2.    As of the First Issuance Date, the Preferred Shares are convertible,
            at the option of the holders, into shares of the Company's Common
            Stock at a per share price equal to the lesser of $11.78 or 110% of
            the average last sale price of the 20 trading days prior to October
            21, 1998, but not less than $8.50 per share. If and whenever, on or
            after the First Issuance Date, the Company issues or sells, or is
            deemed to have issued or sold, any shares of its Common Stock for
            consideration per share less than the conversion price in effect for
            the Preferred Shares immediately prior to the time of such issue or
            sale, then, unless such issuance or sale was a Permitted Issuance
            (as described above), immediately upon such issue or sale or deemed
            issue or sale the conversion price shall be reduced to the
            conversion price determined by dividing (i) the sum of (1) the
            product derived by multiplying the conversion price in effect
            immediately prior to such issue or sale by the number of shares of
            Common Stock deemed outstanding immediately prior to such issue or
            sale, plus (2) the consideration, if any, received by the Company
            upon such issue or sale, by (ii) the number of shares of Common
            Stock deemed outstanding immediately after such issue or sale.

      3.    The dividend rate on the Preferred Shares is 7.5 percent per annum,
            which is payable at the option of the Company in either cash or by
            issuing additional Preferred Shares (on the first four dividend
            payment dates) or by issuing Common Stock (after the fourth dividend
            payment date). However, unless waived by a majority of the holders
            of Preferred Shares, the dividend rate will increase to 20 percent
            per annum, payable solely in cash, if either (i) at any time during
            any 730-day period individuals who constituted the Board of
            Directors at the beginning of such period, or the First Issuance
            Date (whichever is later), cease for any reason to constitute a
            majority of the Board of Directors then in office or (ii) the Board

<PAGE>


            of Directors fails to declare and pay in full, on any semi annual
            Dividend Payment Date (as defined in Section 4 (c) of Exhibit
            3.1.1).

      4.    The Company is restricted from incurring any indebtedness unless
            after giving effect to the additional indebtedness the aggregate
            indebtedness of the Corporation and its subsidiaries outstanding as
            of the date of such incurrence, excluding financing that is secured
            by accounts receivable but not by the Corporation's intellectual
            property licenses or other intellectual property rights, does not
            exceed two and one-half times EBITDA of the Company for the twelve
            month period immediately prior to the date of such incurrence for
            which there are quarterly financial statements available. For
            purposes of this restriction, EBITDA shall mean the sum of (i) net
            income, (ii) interest expense (iii) depreciation and amortization,
            and other non-cash items properly deducted in determining net income
            and (iv) federal, state and local income taxes, computed and
            calculated in accordance with generally accepted accounting
            principles.

      5.    The Company is restricted from paying with respect to its issued and
            outstanding Common Stock any cash dividends, cash distributions not
            classified as dividends, or cash payments on the redemption of such
            Common Stock. This restriction shall apply as long as at least 20
            percent of the issued Preferred Shares remain outstanding.

      6.    For as long as 20% of the Initial Shares (as defined under Section
            7(b) of Exhibit 3.1.1) remain outstanding, the holders of a majority
            of the Preferred Shares, voting separately as a single class in the
            election of directors of the Company, to the exclusion of all other
            classes of the Company's Common Stock and with each share of the
            Preferred Shares entitled to one vote, shall be entitled to elect
            one (1) director to serve on the Company's Board of Directors until
            his successor is duly elected by holders of a majority of the
            Preferred Shares or he is removed from office by holders of a
            majority of the Preferred Shares.

      7.    The holders of the Preferred Shares shall vote separately as a
            single class, and approval of holders of a majority of the
            outstanding shares of Preferred Shares shall be required, whenever a
            shareholder vote is required pursuant to Section 302A.671 of the
            Minnesota Business Corporation Act, or any successor provision
            thereto, for the purpose of according voting rights with respect to
            shares acquired or to be acquired in a control share acquisition (as
            defined in Section 302A.011 Subdivision 38 of the Minnesota Business
            Corporation Act). In addition, holders of Preferred Shares are
            entitled to vote on all other matters requiring shareholder approval
            on an "as if" converted basis.

      8.    Ten years from the First Issuance Date, the Company must elect to
            either (1) require the holder to convert all remaining unconverted
            Preferred Shares into Common Stock upon the payment by the Company
            of a Conversion Fee to the holder, payable in cash or Common Stock,
            or (2) redeem for cash the holder's unconverted Preferred Shares for
            $1,000 per share plus accrued dividends. The conversion fee cannot
            exceed $3.0 million and will be reduced prorata to the extent the
            number of unconverted Preferred Shares at the end of the ten year
            term is less than the number of Preferred Shares issued to the
            holders during the ten year term.

RELATIONSHIP WITH CHRONIMED.
Although the Company believes the agreements that it had with Chronimed since
its July 1, 1994 spin-off were commercially reasonable, such agreements were not
the product of arms-length negotiations. In June 1997, the Company terminated
these agreements (the "Termination Agreement"), except for the Cystadane
Agreement. The Termination Agreement provides that the Company pay Chronimed
compensation equal to $2,500,000, consisting of cash and shares of the Company's
Common Stock. The October 1996 Cystadane Agreement between the Company and
Chronimed applies solely to the domestic distribution of Cystadane. Several of
the Company's directors and executive officers are current or former employees,
shareholders and/or directors of Chronimed. The Termination Agreement and the
October 1996 Cystadane Agreement were approved by all of the independent outside
members of the Company's Board of Directors.

<PAGE>


POSSIBLE VOLATILITY OF STOCK PRICE AND DILUTION OF STOCK - TERMINATION AGREEMENT
WITH CHRONIMED.
The Company paid $250,000 on signing the Termination Agreement in June 1997, and
had a remaining obligation to compensate Chronimed with cash and Common Stock
having a total value of $2,250,000. Cash payments against this remaining
obligation are to be based on a 3 percent temporary royalty on the Company's
product sales, which the Company began paying quarterly on September 30, 1997.
Unregistered shares of Common Stock equal to 1 percent of the Company's
outstanding shares at each quarter end, which the Company began issuing on March
31, 1998, are to be issued quarterly to Chronimed. The Company is obligated to
continue paying the royalties and issuing Common Stock until the sum of all
royalty payments and the market value (as defined below) of all issued Common
Stock equals $2,250,000. The Company is obligated file a registration statement
with the Securities and Exchange Commission to register such shares. The market
value of shares issued to Chronimed as payment against the remaining obligation
of $2,250,000 will be determined as follows: (i) the market value of any such
shares sold within 90 days after the effective date of a registration statement
covering such shares will be equal to the net proceeds realized by Chronimed
from the sale of such shares, or (ii) the market value of any such shares not
sold within 90 days after the effective date of a registration statement
covering such shares will be equal to the average last bid price for shares of
the CompanyAEs Common Stock as reported on Nasdaq for the last five days within
the 90 day period. The Company anticipates Chronimed will sell in the open
market the shares it receives from the Company within the 90 day period. The
Company has the option, regardless of the market price of its Common Stock, to
buy-out for cash the remaining obligation to Chronimed. Through June 30, 1998,
the Company has paid Chronimed approximately $81,000 in royalties and issued
123,056 shares of Common Stock, of which 61,178 shares have been sold by
Chronimed in market transactions for net cash proceeds of $576,183. At June 30,
1998, the Company's unpaid obligation to Chronimed has an estimated value of
approximately $1,146,666, which is classified as a "Current Liability".

There is risk that the Company's current shareholders' ownership could be
substantially diluted and/or the market value of their shares adversely affected
in the event any one or a combination of the following events occur: (1) sales
by Chronimed of the Company's Common Stock cause the price of the Company's
Common Stock to decrease; (2) in the event of a decline in the value of the
Company's Common Stock, the Company would be required to issue more shares in
subsequent periods to satisfy its remaining obligation to Chronimed; or (3) the
Company's sales of future products are significantly less than forecast, which
would decrease the temporary royalty payments that would be applied against the
remaining obligation and, thereby, increase the number of shares required to be
issued to Chronimed. The realization of any one or combination of these risks,
or the decision by the Company to exercise its option to effect a cash buy-out
of the remaining obligation, could have a material adverse effect on the
Company's business, its prospects and its shareholders.

POSSIBLE VOLATILITY OF STOCK PRICE AND REDUCED LIQUIDITY OF THE MARKET FOR THE
STOCK - LOSS OF NASDAQ NATIONAL MARKET LISTING.
There is risk that the market value and the liquidity of the public float for
the Company's Common Stock could be adversely affected in the event the Company
no longer meets the Nasdaq's requirements for continued listing on the National
Market tier. For continued listing on the Nasdaq National Market, a company must
satisfy a number of requirements, which in the Company's case includes either:
(1) net tangible assets in excess of $4.0 million as reported on Form 10-Q or
Form 10-K or (2) a market capitalization of at least $50.0 million. At June 30,
1998, the Company's net tangible assets equaled $669,579 and its market
capitalization was approximately $66.0 million (based on the last sale price of
$10.563 and 6,249,718 shares outstanding as of June 30, 1998). Net tangible
assets are defined as total assets less total liabilities. Market capitalization
is defined as total outstanding shares multiplied by the last sales price quoted
by Nasdaq. After giving effect to the July 23, 1998 private placement of
Preferred Shares, which netted the Company approximately $7.1 million in
additional net tangible assets (i.e., cash), the Company estimates that it will
have net tangible assets in excess of the $4.0 million (thereby satisfying
Nasdaq's net tangible asset listing requirement) through at least the end the
third quarter of 1998. In the event UBS Capital exercises its right, which
expires on October 21, 1998, to invest up to an additional $4.5 million, the
Company's estimated net tangible assets are expected to exceed $4.0 million
through the end of 1998. Should the Company fail to satisfy at least one of the
two aforementioned Nasdaq listing requirements at any time after the third
quarter of

<PAGE>


1998 (or after 1998 in the event of an additional investment by UBS Capital of
at least $2.0 million), the Company's Common Stock would no longer qualify for
listing on the Nasdaq National Market, but would qualify for quotation on the
Nasdaq Small Cap Market provided it had net tangible assets in excess of $2.0
million. The Company's ability to raise additional capital and the market value
of the Company's Common Stock could be adversely affected by failing to meet
Nasdaq's requirements for listing on either the National Market or the Small Cap
Market. The realization of any one or combination of these risks could have a
material adverse effect on the Company's business, its prospects and its
shareholders.

POSSIBLE VOLATILITY OF STOCK PRICE - GENERAL.
There is generally significant volatility in the market prices of securities of
early stage pharmaceutical companies. Contributing to this volatility are
various factors and events, such as the announcements by the Company or its
competitors of new product developments, clinical testing results, governmental
approvals, regulations or actions, developments or disputes relating to patents
or proprietary rights, public concern over the safety of therapies and
fluctuations in financial performance from period to period. These and other
factors and events may have a significant impact on the Company's business and
on the market price of the Common Stock.
