           information is incorporated herein by reference.

ITEM 11.   DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.

           The Registrant is authorized to issue 32,641,926 shares of preferred
           stock of which 11,041,926 shares are designated as Series A preferred
           stock, 10,000,000 shares are designated as Series B preferred stock
           and 4,583,334 are designated as Series C preferred stock. The Series
           A preferred stock, Series B preferred stock and Series C preferred
           stock are referred to in this Registration Statement collectively as
           the "Preferred Stock." As of December 31, 1999, 9,562,301 shares of
           Series A preferred stock (held by 20 holders of record), 9,893,814
           shares of Series B preferred Stock (held by approximately 5,000
           holders of record) and 3,511,111 shares of Series C preferred stock
           (held by one holder of record) were outstanding. In addition, as of
           December 31, 1999, there were outstanding warrants to purchase
           1,137,814 shares of Series A preferred stock and warrants and options
           to purchase 972,223 shares of Series C preferred stock.

           Each share of Preferred Stock bears dividends at the rate of 8% of
           the original purchase price per share per annum, payable when
           declared by the Board of Directors, and is also entitled to a
           dividend equal to any dividend paid to holders of common stock. To
           date, the Board of Directors has not declared any dividends on the
           Preferred Stock or common stock.

           Each share of Preferred Stock is convertible into common stock at any
           time by the holder of such share. All outstanding Preferred Stock of
           a particular series will be automatically converted into common stock
           upon the election of the holders of at least 50% of the outstanding
           shares of such series. In addition all outstanding Preferred Stock
           will be automatically converted into common stock upon the closing of
           a firmly underwritten public offering of our common stock pursuant to
           an effective registration statement under the Securities Act of 1933,
           as amended if the price of the common stock in such offering is at
           least $7.00 per share and the gross cash proceeds to us are at least
           $15,000,000. The number of shares of common stock to which a holder
           is entitled upon conversion of a share of Preferred Stock is equal to
           the original purchase price of the share of Preferred Stock divided
           by the applicable conversion price. The conversion price is equal to
           the original purchase price, subject to adjustment for (i) stock
           dividends, splits, combinations, reclassifications, exchanges, and
           substitutions; (ii) reorganizations, mergers, consolidations and
           sales of assets; and (iii) sales of shares below the conversion
           price. Upon an optional conversion, the Registrant is required to pay
           the converting holder all accumulated and unpaid dividends, whether
           or not declared. Upon a mandatory conversion, all declared and unpaid
           dividends will be payable and all undeclared dividends will be
           canceled.

           The holders of at least 75% of the Series A preferred stock or the
           Series C preferred stock may require the Registrant to redeem all
           of the outstanding Series A preferred stock or Series C preferred
           stock, as the case may be, for a period of three years starting on
           the seventh anniversary of the earliest issue date of the Series A
           preferred stock or Series C preferred stock, for an amount equal to
           the original purchase price of such shares plus accrued and unpaid
           dividends.

           Subject to exceptions described in this paragraph, the Preferred
           Stock is voted equally with the shares of common stock as a single
           class with each holder of shares of Preferred Stock being entitled to
           a number of votes equal to the whole number of shares of common stock
           into which such holder's shares of Preferred Stock are then
           convertible. The holders of the Series A preferred stock, voting as a
           separate class, are entitled to elect two directors, the holders of
           the common stock, voting as a separate class, are entitled to elect
           three directors and the holders of the Preferred Stock and the common
           stock, voting as a single class, are entitled to elect the remaining
           directors. The consent of the holders of at least 67% of the
           outstanding Series A preferred stock and Series C preferred stock,
           voting together as a single class, is required for certain actions,
           including the sale of all or substantially all of the Registrant's
           assets, certain mergers, consolidations or similar transactions,
           changes in the Registrant's line of business, appointment,
           termination or removal of the Registrant's Chief Executive Officer,
           and the Registrant's dissolution or liquidation.

           Upon the Registrant's liquidation or dissolution, the holders of the
           Preferred Stock are entitled to receive an amount equal to the
           original purchase price of their shares plus 8% of such price per
           annum (less previously paid dividends) from the date of issuance
           before any payment is made to holders of common stock. After such
           payment, the Registrant's remaining assets are to be distributed
           ratably to the holders of the Preferred Stock and the common stock.
           Certain consolidations, mergers, asset acquisitions and asset sales
           are treated as liquidations.

           The Registrant may not pay any dividends or make any other
           distributions on any stock ranking junior to the Preferred Stock, and
           may not redeem or otherwise acquire for value any such junior stock,
           until all dividends on the Preferred Stock have been paid or declared
           and set apart.

           There is no public market for the Preferred Stock although some
           banking institutions in Iceland have been making a market for
           privately negotiated transactions among non-U.S. persons in the
           Series B preferred stock. The Registrant's stock transfer records
           indicate that approximately 10 million shares of Series B preferred
           stock were transferred during 1999 in approximately 7,000
           transactions and approximately 1.1 million shares of Series B
           preferred stock were transferred during January 2000 in approximately
           2,700 transactions. The majority of these transactions had an
           Icelandic financial institution as one of the counterparties.

4.5.2(b), the number of authorized shares of Common Stock may be increased or
decreased (but not below the number of shares of Common Stock then outstanding)

Corporation (voting together, on an as-if converted basis).

         4.3  Issuance, Designation of Preferred Stock. Subject to Section
4.5.2(b), the Preferred Stock may be issued from time to time in one or more
series. The Board of Directors is hereby authorized, within the limitations and

subsequent to the issue of shares of that series, but not below the number of
shares of such series then outstanding. In case the number of shares of any
series shall be so decreased, the shares constituting such decrease shall resume
the status which they had prior to the adoption of the resolution originally
fixing the number of shares of such series.

         4.4  Designation of Preferred Shares. Thirteen Million Four Hundred
Thousand (13,400,000) of the authorized shares of Preferred Stock are hereby
designated "Series A Preferred Stock" (the "Series A Preferred"), Five Million
(5,000,000) of the authorized shares of Preferred Stock are hereby designated

Hundred Eighty-three Thousand Three Hundred Thirty-four (4,583,334) of the
authorized shares of Preferred Stock are hereby designated "Series C Preferred
Stock" (the "Series C Preferred").

         4.5 Rights, etc. of Preferred Stock. The rights, preferences,
privileges, restrictions and other matters relating to the Series A Preferred,
the Series B Preferred and the Series C Preferred are as follows:

               4.5.1    Dividend Rights.


                        (a)      Generally.  Holders of Series A Preferred,
Series B Preferred and Series C Preferred, together as a separate class and in
preference to the holders of any other stock of the Corporation, including any
Common Stock and all other classes or series of stock issued by the Corporation
(all such stock, "Junior Stock"), shall be entitled to receive, when and as
declared by the Board of Directors, but only out of funds that are legally
available therefor, cash dividends at the rate of eight percent (8%) of the
Original Issue Price per annum on each outstanding



                                       -2-
<PAGE>   3
share of Series A Preferred, Series B Preferred and Series C Preferred Stock (as
adjusted for any stock dividends, combinations, splits, recapitalizations and
the like with respect to such shares). The "Original Issue Price" of the Series
A Preferred shall be the purchase price paid in connection with the issuance of
each respective share of Series A Preferred. The "Original Issue Price" of the
Series B Preferred shall be the purchase price paid in connection with the
issuance of each respective share of Series B Preferred. The "Original Issue
Price" of the Series C Preferred shall be the purchase price paid in connection
with the issuance of each respective share of Series C Preferred. Such dividends
not declared and paid shall accumulate, but shall not accrue any interest.

                        (b)      Dividends on Junior Stock.  So long as any
shares of Series A Preferred, Series B Preferred or Series C Preferred shall be
outstanding, no dividend, whether in cash or property, shall be paid or
declared, nor shall any other distribution be made, on any Junior Stock, nor
shall any shares of any Junior Stock of the Corporation be purchased, redeemed,
or otherwise acquired for value by the Corporation (except for acquisitions of
Common Stock by the Corporation pursuant to agreements which permit the
Corporation to repurchase such shares upon termination of services to the
Corporation or in exercise of the Corporation's right of first refusal upon a
proposed transfer) until all dividends (set forth in Section 4.5.1(a) above) on
the Series A Preferred, Series B Preferred and the Series C Preferred shall have
been paid or declared and set apart. In the event dividends are paid on any
share of Common Stock, an additional dividend shall be paid with respect to all
outstanding shares of Series A Preferred, Series B Preferred and Series C
Preferred in an amount equal per share (on an as-converted to Common Stock
basis) to the amount paid or set aside for each share of Common Stock. The
provisions of this Section 4.5.1(b) shall not, however, apply to (i) a dividend
payable in Common Stock, (ii) the acquisition of shares of any Junior Stock in
exchange for shares of any other Junior Stock, or (iii) any repurchase of any
outstanding securities of the Corporation that is unanimously approved by the
Corporation's Board of Directors.

               4.5.2    Voting Rights.


                        (a)      Generally.  Except as otherwise provided herein
or as required by law, the Series A Preferred, Series B Preferred and Series C
Preferred shall be voted equally with the shares of the Common Stock and not as
a separate class, at any annual or special meeting of shareholders of the
Corporation, and may act by written consent in the same manner as the Common
Stock, in either case upon the following basis: each holder of shares of Series
A Preferred, Series B Preferred and Series C Preferred shall be entitled to such
number of votes as shall be equal to the whole number of shares of Common Stock
into which such holder's aggregate




                                       -3-

number of shares of Series A Preferred, Series B Preferred or Series C Preferred
are convertible (pursuant to Section 4.5.4 hereof) immediately after the close
of business on the record date fixed for such meeting or the effective date of
such written consent.

special rights or privileges, qualifications, limitations, or restrictions of
the Series A Preferred and the Series C Preferred Stock;

                                 (ii)    Any authorization or any designation,
whether by reclassification or otherwise, of any new class or series of stock or
any other securities convertible into equity securities of the Corporation

Preferred in right of redemption, liquidation preference, voting or dividends or
any increase in the authorized or designated number of any such new class or
series;

                                 (iii)   Any redemption, repurchase, payment of
dividends or other distributions with respect to Junior Stock (except for

               4.5.3    Liquidation Rights.

                        (a)      Preference.  Upon any liquidation, dissolution,
or winding up of the Corporation, whether voluntary or involuntary, before any
distribution or payment shall be made to the holders of any Junior Stock, the
holders of the Series A Preferred, the Series B Preferred and the Series C
Preferred shall be entitled to be paid out of the assets of the Corporation an
amount per share of the Series A Preferred, the Series B Preferred and the
Series C Preferred equal to the sum of (i) the respective Original Issue Price
thereof, plus (ii) an amount equal to eight percent (8%) of such Original Issue
Price per annum from the Original Issue Date until the date of payment (less the
per share amount of any dividends previously paid on such shares) (as adjusted
for any stock dividends, combinations, splits, recapitalizations and the like

Preferred or Series C Preferred held by them. For purposes of this Section 4.5,
"Original Issue Date" shall mean the date on which each share of the Series A
Preferred, each share of Series B Preferred or each share of Series C Preferred,
as the case may be, is issued.

                        (b)      Remaining Assets.  After the payment of the
full liquidation preference of the Series A Preferred, the Series B Preferred
and the Series C Preferred as set forth in Section 4.5.3(a), the assets of the
Corporation legally available for distribution, if any, shall be distributed
ratably to the holders of the Common Stock and the Series A Preferred, the

                                 (i)     any consolidation or merger of the
Corporation with or into any other corporation or other entity or person, or any
other corporate reorganization, in which the stockholders of the Corporation
immediately prior to such consolidation, merger or reorganization, own less than
fifty percent (50%) of the Corporation's voting power immediately after such
consolidation, merger or reorganization, or any transaction or series of related
transactions in which in excess of fifty percent (50%) of the Corporation's
voting power is transferred (an "Acquisition"); or

                                 (ii)    a sale, lease, transfer or other
disposition of all or substantially all of the assets of the Corporation (an
"Asset Transfer").

<PAGE>   8
                        (d)      Insufficient Assets.  If, upon any liquidation,
distribution, or winding up, the assets of the Corporation shall be insufficient
to make payment in full to all holders of the Series A Preferred, the Series B
Preferred and the Series C Preferred of the liquidation preference set forth in
Section 4.5.3(a), then such assets shall be distributed among the holders of the
Series A Preferred, the Series B Preferred and the Series C Preferred at the
time outstanding, ratably in proportion to the full amounts to which they would
otherwise be respectively entitled.

               4.5.4    Conversion Rights.

               The holders of the Series A Preferred, the Series B Preferred
and the Series C Preferred shall have the following rights, respectively, with
respect to the conversion of the Series A Preferred, the Series B Preferred and
the Series C Preferred into shares of Common Stock (collectively, the
"Conversion Rights"):

                        (a)      Optional Conversion.  Subject to and in
compliance with the provisions of this Section 4.5.4, any shares of Series A
Preferred, Series B Preferred or Series C Preferred may, at the option of the
holder, be converted at any time into fully paid and nonassessable shares of
Common Stock. The number of shares of Common Stock to which a holder of Series A
Preferred shall be entitled upon conversion shall be the product obtained by
multiplying the Series A Preferred Rate then in effect (determined as provided
in Section 4.5.4(b)(i)) by the number of shares of Series A Preferred being
converted. The number of shares of Common Stock to which a holder of Series B
Preferred shall be entitled upon conversion shall be the product obtained by
multiplying the Series B Preferred Rate then in effect (determined as provided
in Section 4.5.4(b)(ii)) by the number of shares of Series B Preferred being
converted. The number of shares of Common Stock to which a holder of Series C
Preferred shall be entitled upon conversion shall be the product obtained by
multiplying the Series C Preferred Rate then in effect (determined as provided
in Section 4.5.4(b)(iii)) by the number of shares of Series C Preferred being
converted.

                        (b)      Preferred Rate.

                                 (i)     The conversion rate in effect at any
time for conversion of the Series A Preferred (the "Series A Preferred Rate")
shall be the quotient obtained by dividing the Original Issue Price of the
Series A Preferred by the Series A Preferred Price, calculated as provided in
Section 4.5.4(c)(i).

                                 (ii)    The conversion rate in effect at any
time for conversion of the Series B Preferred (the "Series B Preferred Rate")
shall be the quotient obtained by dividing the Original Issue Price of the
Series B Preferred by the Series B Preferred Price, calculated as provided in
Section 4.5.4(c)(ii).



                                       -8-
<PAGE>   9
                                 (iii)    The conversion rate in effect at any
time for conversion of the Series C Preferred (the "Series C Preferred Rate")
shall be the quotient obtained by dividing the Original Issue Price of the
Series C Preferred by the Series C Preferred Price, calculated as provided in
Section 4.5.4(c)(iii).

                        (c)      Preferred Price.

                                 (i)     For purposes of this Section 4.5.4,
the conversion price for the Series A Preferred (the "Series A Preferred Price")
shall initially be the Original Issue Price of the Series A Preferred. The
Series A Preferred Price shall be adjusted from time to time in accordance with
this Section 4.5.4. All references to the Series A Preferred Price herein shall
mean the Series A Preferred Price as so adjusted.

                                 (ii)    For purposes of this Section 4.5.4, the
conversion price for the Series B Preferred (the "Series B Preferred Price")
shall initially be the Original Issue Price of the Series B Preferred. The
Series B Preferred Price shall be adjusted from time to time in accordance with
this Section 4.5.4. All references to the Series B Preferred Price herein shall
mean the Series B Preferred Price as so adjusted.

                                 (iii)   For purposes of this Section 4.5.4, the
conversion price for the Series C Preferred (the "Series C Preferred Price")
shall initially be the Original Issue Price of the Series C Preferred. The
Series C Preferred Price shall be adjusted from time to time in accordance with
this Section 4.5.4. All references to the Series C Preferred Price herein shall
mean the Series C Preferred Price as so adjusted.

                        (d)      Mechanics of Conversion. Each holder of the
Series A Preferred, the Series B Preferred or the Series C Preferred who desires
to convert the same into shares of Common Stock pursuant to Section 4.5.4(a)
shall surrender the certificate or certificates therefor, duly endorsed, at the
office of the Corporation or any transfer agent for the Series A Preferred, the
Series B Preferred or the Series C Preferred, as the case may be, and shall give
written notice to the Corporation at such office that such holder elects to
convert the same. Such notice shall state the number of shares of Series A
Preferred, Series B Preferred or Series C Preferred being converted. Thereupon,
the Corporation shall promptly issue and deliver at such office to such holder a
certificate or certificates for the number of shares of Common Stock to which
such holder is entitled and shall promptly pay in cash or, to the extent
sufficient funds are not then legally available therefor, in Common Stock (at
the Common Stock's fair market value determined by the Board of Directors as of
the date of such conversion), any accumulated and unpaid dividends as provided
in Section 4.5.1(a), whether or not declared on the shares of Series A
Preferred, Series B Preferred or Series C Preferred being




                                       -9-
<PAGE>   10
converted. Such conversion shall be deemed to have been made at the close of
business on the date of such surrender of the certificates representing the
shares of Series A Preferred, Series B Preferred or Series C Preferred to be
converted, and the person entitled to receive the shares of Common Stock
issuable upon such conversion shall be treated for all purposes as the record
holder of such shares of Common Stock on such date.

                        (e)      Adjustment for Stock Splits and Combinations.
If the Corporation shall, at any time or from time to time after the respective
Original Issue Dates of the Series A Preferred, the Series B Preferred and the
Series C Preferred, effect a subdivision of the outstanding Common Stock without
a corresponding subdivision of the Series A Preferred, the Series B Preferred
and/or the Series C Preferred, the Series A Preferred Price, the Series B
Preferred Price and/or the Series C Preferred Price, as the case may be, in
effect immediately before that subdivision shall be proportionately decreased.
Conversely, if the Corporation shall, at any time or from time to time after the
respective Original Issue Dates of the Series A Preferred, the Series B
Preferred or the Series C Preferred, combine the outstanding shares of Common
Stock into a smaller number of shares without a corresponding combination of the
Series A Preferred, the Series B Preferred and/or the Series C Preferred, the
Series A Preferred Price, the Series B Preferred Price and/or the Series C
Preferred Price, as the case may be, in effect immediately before the
combination shall be proportionately increased. Any adjustment under this
Section 4.5.4(e) shall become effective at the close of business on the date the
subdivision or combination becomes effective.

                        (f)      Adjustment for Common Stock Dividends and
Distribution. If the Corporation, at any time or from time to time after the
respective Original Issue Dates of the Series A Preferred, the Series B
Preferred and the Series C Preferred, makes, or fixes a record date for the
determination of holders of Common Stock entitled to receive, a dividend or
other distribution payable in additional shares of Common Stock, in each such
event the Series A Preferred Price, the Series B Preferred Price and the Series
C Preferred Price that are then in effect shall each be decreased as of the time
of such issuance or, in the event such record date is fixed, as of the close of
business on such record date, by multiplying each of the Series A Preferred
Price, the Series B Preferred Price and the Series C Preferred Price then in
effect by a fraction (i) the numerator of which is the total number of shares of
Common Stock issued and outstanding immediately prior to the time of such
issuance or the close of business on such record date, and (ii) the denominator
of which is the total number of shares of Common Stock issued and outstanding
immediately prior to the time of such issuance or the close of business on such
record date plus the number of shares of Common Stock issuable in payment of
such dividend or distribution; provided, however, that if such record date is
fixed and such dividend is not fully paid or




                                      -10-
<PAGE>   11
if such distribution is not fully made on the date fixed therefor, the Series A
Preferred Price, the Series B Preferred Price and the Series C Preferred Price
shall be adjusted pursuant to this Section 4.5.4(f) to reflect the actual
payment of such dividend or distribution.

                        (g)      Adjustments for Other Dividends and
Distributions. If the Corporation, at any time or from time to time after the
respective Original Issue Dates of the Series A Preferred, the Series B
Preferred and the Series C Preferred, makes, or fixes a record date for the
determination of holders of Common Stock entitled to receive, a dividend or
other distribution payable in securities of the Corporation other than shares of
Common Stock, in each such event provision shall be made so that the holders of
the Series A Preferred, the Series B Preferred and the Series C Preferred shall
receive upon conversion thereof, in addition to the number of shares of Common
Stock receivable thereupon, the amount of other securities of the Corporation
which they would have received had their Series A Preferred, Series B Preferred
or Series C Preferred, as the case may be, been converted into Common Stock on
the date of such event and had they thereafter, during the period from the date
of such event to an including the conversion date, retained such securities
receivable by them as aforesaid during such period, subject to all other
adjustments called for during such period under this Section 4.5.4 with respect
to the rights of the holders of the Series A Preferred, Series B Preferred and
Series C Preferred or with respect to such other securities by their terms.

                        (h)      Adjustment for Reclassification, Exchange and
Substitution. If, at any time or from time to time after the respective Original
Issue Dates of the Series A Preferred, the Series B Preferred and the Series C
Preferred, the Common Stock issuable upon the conversion of the Series A
Preferred, the Series B Preferred or the Series C Preferred is changed into the
same or a different number of shares of any class or classes of stock, whether
by recapitalization, reclassification or otherwise (other than an Acquisition or
Asset Transfer as defined in Section 4.5.3(c) or a subdivision or combination of
shares of stock dividend or a reorganization, merger consolidation or sale of
assets provided or elsewhere in this Section 4.5.4), in any such event each
holder of Series A Preferred, Series B Preferred or Series C Preferred, as the
case may be, shall have the right thereafter to convert such stock into the kind
and amount of stock and other securities and property that is receivable upon
such recapitalization, reclassification or other change by holders of the
maximum number of shares of Common Stock into which such shares of Series A
Preferred, Series B Preferred or Series C Preferred could have been converted
immediately prior to such recapitalization, reclassification or change, all
subject to further adjustment as provided herein or with respect to such other
securities or property by the terms thereof.









                                      -11-
<PAGE>   12
                        (i)      Reorganizations, Mergers, Consolidations or
Sales of Assets. If, at any time or from time to time after the respective
Original Issue Dates of the Series A Preferred, the Series B Preferred and the
Series C Preferred, there is a capital reorganization of the Common Stock (other
than an Acquisition or Asset Transfer as defined in Section 4.5.3(c) or a
recapitalization, subdivision, combination, reclassification, exchange or
substitution of shares provided for elsewhere in this Section 4.5.4), as a part
of such capital reorganization, provision shall be made so that the holders of
the Series A Preferred, the Series B Preferred and the Series C Preferred shall
thereafter be entitled to receive upon conversion of the Series A Preferred,
Series B Preferred and the Series C Preferred, as the case may be, the number of
shares of stock or other securities or property of the Corporation to which a
holder of the number of shares of Common Stock deliverable upon conversion would
have been entitled on such capital reorganization, subject to adjustment in
respect of such stock or securities by the terms thereof. In any such case,
appropriate adjustment shall be made in the application of the provisions of
this Section 4.5.4 with respect to the rights of the holders of Series A
Preferred, Series B Preferred and Series C Preferred after the capital
reorganization to the end that the provisions of this Section 4.5.4 (including
adjustment of the Series A Preferred Price, the Series B Preferred Price and the
Series C Preferred Price then in effect and the number of shares issuable upon
conversion of the Series A Preferred, the Series B Preferred and the Series C
Preferred) shall be applicable after that event and be as nearly equivalent as
practicable.

                        (j)      Sale of Shares Below Preferred Price.

                                 (i)     If, at any time or from time to time
after the respective Original Issue Dates of the Series A Preferred, the Series
B Preferred and the Series C Preferred, the Corporation issues or sells, or is
deemed by the express provisions of this Section 4.5.4(j) to have issued or
sold, Additional Shares of Common Stock (as hereinafter defined), other than as
a dividend or other distribution on any class of stock as provided in Section
4.5.4(f), and other than a subdivision or combination of shares of Common Stock
as provided in Section 4.5.4(e), for an Effective Price (as hereinafter defined)
less than the then effective Series A Preferred Price, the then effective Series
B Preferred Price or the then effective Series C Preferred Price, as the case
may be, then and in each such case the then existing Series A Preferred Price,
the then existing Series B Preferred Price or the then existing Series C
Preferred Price, as the case may be, shall be reduced, as of the opening of the
business on the date of such issue or sale, to a price according to the
following formula:






                                      -12-
<PAGE>   13
                                                             A + B
                        X        =       Y        x        ---------
                                                               C

               Where:

                        X        =       the new Series A Preferred Price,
                                         the new Series B Preferred Price or
                                         the new Series C Preferred Price, as
                                         the case may be;

                        Y        =       the then existing Series A
                                         Preferred Price, the then existing
                                         Series B Preferred Price or the then
                                         existing Series C Preferred Price,
                                         as the case may be;

                        A        =       the number of shares of Common
                                         Stock deemed outstanding (as defined
                                         below) immediately prior to such
                                         issue or sale;

                        B        =       the number of shares of Common
                                         Stock which the aggregate
                                         consideration received (as defined
                                         in Section 4.5.4(j)(ii)) by the
                                         Corporation for the total number of
                                         Additional Shares of Common Stock so
                                         issued would purchase at the then
                                         existing Series A Preferred Price,
                                         the then existing Series B Preferred
                                         Price or the then existing Series C
                                         Preferred Price, as the case may be;
                                         and

                        C        =       the number of shares of Common
                                         Stock deemed outstanding (as defined
                                         below) immediately prior to such
                                         issue or sale plus the total number
                                         of Additional Shares of Common Stock
                                         so issued.

For the purposes of the preceding sentence, the number of shares of Common Stock
deemed to be outstanding as of a given date shall be the sum of (A) the number
of shares of Common Stock actually outstanding, and (B) the aggregate number of
shares of Common Stock into which the then outstanding shares of Series A
Preferred, Series B Preferred and Series C Preferred could be converted if fully
converted on the day immediately preceding the given date.

                                 (ii)    For the purpose of making any
adjustment required under this Section 4.5.4(j), the consideration received by
the Corporation for any issue or sale of securities shall: (A) to the extent it
consists of cash, be computed at the net amount of cash received by the
Corporation after deduction of any




                                      -13-
<PAGE>   14
underwriting or similar commissions, compensation, or concessions paid or
allowed by the Corporation in connection with such issue or sale but without
deduction of any expenses payable by the Corporation, (B) to the extent it
consists of property other than cash, be computed at the fair value of that
property as determined in good faith by the Board of Directors, and (C) if
Additional Shares of Common Stock, Convertible Securities (as hereinafter
defined) or rights or options to purchase either Additional Shares of Common
Stock or Convertible Securities are issued or sold together with other stock or
securities or other assets of the Corporation for a consideration which covers
both, be computed as the portion of the consideration so received that may be
reasonably determined in good faith by the Board of Directors to be allocable to
such Additional Shares of Common Stock, Convertible Securities or rights or
options.

                                 (iii)   For the purpose of the adjustment
required under this Section 4.5.4(j), if the Corporation issues or sells any
rights or options for the purchase of, or stock or other securities convertible
into, Additional Shares of Common Stock (such convertible stock or securities
being referred to as "Convertible Securities") and if the Effective Price of
such Additional Shares of Common Stock is less than the Series A Preferred
Price, the Series B Preferred Price and/or the Series C Preferred Price, as the
case may be, in each case the Corporation shall be deemed to have issued at the
time of the issuance of such rights or options or Convertible Securities the
maximum number of Additional Shares of Common Stock issuable upon the exercise
or conversion thereof and to have received as consideration for the issuance of
such shares an amount equal to the total amount of consideration, if any,
received by the Corporation for the issuance of such rights or options or
Convertible Securities, plus, in the case of such rights or options, the minimum
amounts of consideration, if any, payable to the Corporation upon the exercise
of such rights or options, plus, in the case of Convertible Securities, the
minimum amounts of consideration, if any, payable to the Corporation (other than
by cancellation of liabilities or obligations evidenced by such Convertible
Securities) upon the conversion thereof; provided that if in the case of
Convertible Securities the minimum amounts of such consideration cannot be
ascertained, but are a function of anti-dilution or similar protective clauses,
the Corporation shall be deemed to have received the minimum amounts of
consideration without reference to such clauses; and provided further that if
the minimum amount of consideration payable to the Corporation upon the exercise
or conversion of rights, options or Convertible Securities is reduced over time
or on the occurrence or nonoccurrence of specified events other than by reason
of anti-dilution adjustments, the Effective Price shall be recalculated using
the figure to which such minimum amount of consideration is reduced; and
provided further that if the minimum amount of consideration payable to the
Corporation upon the exercise or conversion of such rights, options or
Convertible Securities is subsequently increased, the Effective



                                      -14-
<PAGE>   15
Price shall be again recalculated using the increased minimum amount of
consideration payable to the Corporation upon the exercise or conversion of such
rights, options or Convertible Securities. No further adjustment of the Series A
Preferred Price, the Series B Price and/or the Series C Preferred Price, as
adjusted upon the issuance of such rights, options or Convertible Securities,
shall be made as a result of the actual issuance of Additional Shares of Common
Stock on the exercise of any such rights or options or the conversion of any
such Convertible Securities. If any such rights or options or the conversion
privileges represented by any such Convertible Securities shall expire without
having been exercised, the Series A Preferred Price, the Series B Preferred
Price and/or the Series C Preferred Price, as adjusted upon the issuance of such
rights, options or Convertible Securities, shall be readjusted to the Series A
Preferred Price, the Series B Preferred Price and/or the Series C Preferred
Price which would have been in effect had an adjustment been made on the basis
that the only Additional Shares of Common Stock so issued were the Additional
Shares of Common Stock, if any, actually issued or sold on the exercise of such
rights or options or rights of conversion of such Convertible Securities, and
such Additional Shares of Common Stock, if any, were issued or sold for the
consideration actually received by the Corporation upon such exercise, plus the
consideration, if any, actually received by the Corporation for the granting of
all such rights or options, whether or not exercised, plus the consideration
received for issuing or selling the Convertible Securities actually converted,
plus the consideration, if any, actually received by the Corporation (other than
by cancellation of liabilities or obligations evidenced by such Convertible
Securities) on the conversion of such Convertible Securities, provided that such
readjustment shall not apply to prior conversions of Series A Preferred, Series
B Preferred and Series C Preferred.

                                 (iv)    "Additional Shares of Common Stock"
shall mean all shares of Common Stock issued by the Corporation or deemed to be
issued pursuant to this Section 4.5.4(j), whether or not subsequently reacquired
or retired by the Corporation other than (A) shares of Common Stock issued upon
conversion of the Series A Preferred, the Series B Preferred and the Series C
Preferred; (B) up to 1,900,000 shares of Common Stock and/or options, warrants
or other Common Stock purchase rights, and the Common Stock issued pursuant to
such options, warrants or other rights (as adjusted for any stock dividends,
combinations, splits, recapitalizations and the like) issued after the
respective Original Issue Dates of the Series A Preferred, the Series B
Preferred and the Series C Preferred to employees, officers or directors of, or
consultants and advisors to, the Corporation or any subsidiary pursuant to stock
purchase or stock option plans or other arrangements that are approved by the
Board of Directors; and (C) shares of Common Stock issued pursuant to the
exercise of options, warrants or convertible securities outstanding, or
securities issued pursuant to any rights




                                      -15-
<PAGE>   16
or agreements outstanding, as of the respective Original Issue Dates of the
Series A Preferred, the Series B Preferred and the Series C Preferred. The
"Effective Price" of Additional Shares of Common Stock shall mean the quotient
determined by dividing the total number of Additional Shares of Common Stock
issued or sold, or deemed to have been issued or sold by the Corporation under
this Section 4.5.4(j), into the aggregate consideration received, or deemed to
have been received, by the Corporation for such issue under this Section
4.5.4(j), for such Additional Shares of Stock.

                       (k)       Accountants' Certificate of Adjustment.  In
each case of an adjustment or readjustment of the Series A Preferred Price, the
Series B Preferred Price and/or the Series C Preferred Price for the number of
shares of Common Stock or other securities issuable upon conversion of the
Series A Preferred, the Series B Preferred or the Series C Preferred, if the
Series A Preferred, the Series B Preferred and/or the Series C Preferred, as the
case may be, is then covered by this Section 4.5.4, the Corporation, at its
expense, shall compute such adjustment or readjustment in accordance with the
provisions hereof and prepare a certificate showing such adjustment or
readjustment, and shall mail such certificate, by first class mail, postage
prepaid to each registered holder of the Series A Preferred, the Series B
Preferred and/or the Series C Preferred at the holder's address as shown in the
Corporation's books. The Certificate shall set forth such adjustment or
readjustment, showing in detail the facts upon which such adjustment or
readjustment is based, including a statement of (i) the consideration received
or deemed to be received by the Corporation for any Additional Shares of Common
Stock issued or sold or deemed to have been issued or sold, (ii) the Series A
Preferred Price, Series B Preferred Price or Series C Preferred Price at the
time in effect, (iii) the number of Additional Shares of Common Stock, and (iv)
the type and amount, if any, of other property which at the time would be
received upon conversion of the Series A Preferred, the Series B Preferred or
the Series C Preferred.

                        (l)      Notices of Record Date.  Upon (i) any taking
by the Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend or other distribution, or (ii) any Acquisition (as defined in Section
4.5.3(c)(i)) or other capital reorganization of the Corporation, any
reclassification or recapitalization of the capital stock of the Corporation,
any merger or consolidation of the Corporation with or into any other
corporation, or any Asset Transfer (as defined in Section 4.5.3(c)(ii)), or any
voluntary or involuntary dissolution, liquidation or winding up of the
Corporation, the Corporation shall mail to each holder of Series A Preferred,
Series B Preferred and Series C Preferred at least twenty (20) days prior to the
record date specified therein a notice specifying: (A) the date on which any
such record is to be taken for the purpose of such dividend or

                                      -16-
<PAGE>   17
distribution and a description of such dividend or distribution, (B) the date on
which any such Acquisition, reorganization, reclassification, transfer,
consolidation, merger, Asset Transfer, dissolution, liquidation or winding up is
expected to become effective, and (C) the date, if any, that is to be fixed as
to when the holders of record of Common Stock (or other securities) shall be
entitled to exchange their shares of Common Stock (or other securities) for
securities or other property deliverable upon such Acquisition, reorganization,
reclassification, transfer, consolidation, merger, Asset Transfer, dissolution,
liquidation or winding up.

                        (m)      Automatic Conversion.

                                 (i)     (A) Each share of Series A Preferred
shall automatically be converted into shares of Common Stock, based on the
then-effective Series A Preferred Price, at any time upon the affirmative
election of the holders of at least fifty percent (50%) of the outstanding
shares of the Series A Preferred, voting as a separate class. (B) Each share of
Series B Preferred shall automatically be converted into shares of Common Stock,
based on the then-effective Series B Preferred Price at any time upon the
affirmative election of the holders of at least fifty percent (50%) of the
outstanding shares of the Series B Preferred, voting as a separate class. (C)
Each share of Series C Preferred shall automatically be converted into shares of
Common Stock, based on the then-effective Series C Preferred Price at any time
upon the affirmative election of the holders of at least fifty percent (50%) of
the outstanding shares of the Series C Preferred, voting as a separate class.
Upon any conversion pursuant to this Section 4.5.4(m)(i), any declared and
unpaid dividends shall be paid in accordance with the provisions of Sections
4.5.4(d) and 4.5.1(a), and any undeclared dividends shall be canceled.

                                 (ii)    Each share of the Series A Preferred,
Series B Preferred and Series C Preferred shall automatically be converted into
shares of Common Stock, based on the then effective Series A Preferred Price,
Series B Preferred Price and Series C Preferred Price, as the case may be,
immediately upon the closing of a firmly underwritten public offering pursuant
to an effective registration statement under the United States Securities Act of
1933, as amended (the "Securities Act"), covering the offer and sale of Common
Stock for the account of the Corporation in which (A) the per share is at least
$7.00 (such price subject to equitable adjustment in the event of any stock
dividend, stock split, combination, reorganization, recapitalization,
reclassification or similar such event involving a change in the Common Stock),
and (B) the gross cash proceeds to the Corporation (before underwriting
discounts, commissions and fees) are at least $15,000,000 (such offer and sale,
a "Qualified Public Offering"); provided, however, that in the event of any
conversion pursuant to this Section 4.5.4(m)(ii), the minimum number of shares
of Common




                                      -17-
<PAGE>   18
Stock to be issued upon such conversion shall be adjusted on a one-to-one basis
with respect to each share of Series A Preferred, Series B Preferred or Series C
Preferred, as the case may be, to be converted. Upon any conversion pursuant to
this Section 4.5.4(m)(ii), any declared and unpaid dividends shall be paid in
accordance with the provisions of Sections 4.5.4(d) and 4.5.1(a), and any
undeclared dividends shall be canceled.

                                 (iii)   Upon the occurrence of the event
specified in Section 4.5.4(m)(i) or (ii), the outstanding shares of Series A
Preferred, Series B Preferred and/or Series C Preferred, as the case may be,
shall be converted automatically without any further action by the holders of
such shares and whether or not the certificates representing such shares are
surrendered to the Corporation or its transfer agent; provided, however, that
the Corporation shall not be obligated to issue certificates evidencing the
shares of Common Stock issuable upon such conversion unless the certificates
evidencing such shares of Series A Preferred, Series B Preferred and/or Series C
Preferred are either delivered to the Corporation or its transfer agent as
provided below, or the holder notifies the Corporation or its transfer agent
that such certificates have been lost, stolen or destroyed and executes an
agreement satisfactory to the Corporation to indemnify the Corporation from any
loss incurred by it in connection with such certificates. Upon the occurrence of
such automatic conversion of the Series A Preferred, Series B and/or the Series
C Preferred, as the case may be, the holders of Series A Preferred, Series B
Preferred or Series C Preferred shall surrender the certificates representing
such shares at the office of the Corporation or any respective transfer agents
for the Series A Preferred, Series B Preferred and Series C Preferred.
Thereupon, there shall be issued and delivered to such holder promptly at such
office and in its name as shown on such surrendered certificate or certificates,
a certificate or certificates for the number of shares of Common Stock into
which the shares of Series A Preferred, Series B Preferred or Series C Preferred
surrendered were convertible on the date on which such automatic conversion
occurred, and any declared and unpaid dividends shall be paid in accordance with
the provisions of Sections 4.5.4(d) and 4.5.1(a), and any undeclared dividends
shall be canceled.

                        (n)      Fractional Shares.  No fractional shares of
Common Stock shall be issued upon conversion of Series A Preferred, Series B
Preferred or Series C Preferred. All shares of Common Stock (including fractions
thereof) issuable upon conversion of more than one share of Series A Preferred,
Series B Preferred or Series C Preferred by a holder thereof shall be aggregated
for purposes of determining whether the conversion would result in the issuance
of any fractional share. If, after such aggregation, the conversion would result
in the issuance of any fractional share, the Corporation shall, in lieu of
issuing any fractional share, pay cash equal to the product of such fraction
multiplied by the Common




                                      -18-
<PAGE>   19
Stock's fair market value (as determined by the Board) on the date of
conversion.

                        (o)      Reservation of Stock Issuable Upon Conversion.
The Corporation shall at all times reserve and keep available out of its
authorized but unissued shares of Common Stock, solely for the purpose of
effecting the conversion of the shares of the Series A Preferred, the Series B
Preferred and the Series C Preferred, such number of its shares of Common Stock
as shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series A Preferred, the Series B Preferred and the
Series C Preferred, on a fully diluted basis. If at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of the Series A Preferred, the
Series B Preferred and the Series C Preferred, on a fully diluted basis, the
Corporation will take such corporate action as may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purpose.

                        (p)      Notices. Any notice required by the provisions
of this Section 4.5.4 shall be in writing and shall be deemed effectively given:
(i) upon personal delivery to the party to be notified, (ii) when sent by
confirmed telex or facsimile if sent during normal business hours of the
recipient, or if not, then on the next business day, (ii) five (5) days after
having been sent by registered or certified mail, return receipt requested,
postage prepaid, or (iv) one (1) day after deposit with a nationally recognized
overnight courier, specifying the next day delivery, with written verification
of receipt. All notices shall be addressed to each holder of record at the
address of such holder appearing on the books of the Corporation.

                        (q)      Payment of Taxes. The Corporation will pay all
taxes (other than taxes based upon income) and other governmental charges that
may be imposed with respect to the issue or delivery of shares of Common Stock
upon conversion of shares of Series A Preferred, Series B Preferred or Series C
Preferred, excluding any tax or other charge imposed in connection with any
transfer involved in the issue and delivery of shares of Common Stock in a name
other than that in which the shares of Series A Preferred, Series B Preferred or
Series C Preferred so converted were registered.

               4.5.5    Redemption.

                        (a)      The Corporation shall be obligated to redeem
the Series A Preferred and the Series C Preferred as follows:

                                 (i)     The holders of at least seventy-five
percent (75%) of the then outstanding shares of Series A Preferred,




                                      -19-
<PAGE>   20
voting together as a class, may require the Corporation, to the extent it may
lawfully do so, to redeem the Series A Preferred in three (3) equal annual
installments beginning on the seventh (7th) anniversary of the earliest Original
Issue Date of the Series A Preferred, and ending on three (3) years from such
first redemption date (each redemption date, a "Series A Redemption Date"). The
Corporation shall effect such redemptions on the applicable Series A Redemption
Date by paying in cash in exchange for the shares of Series A Preferred to be
redeemed a sum equal to the Original Issue Price per share of Series A Preferred
(as adjusted for any stock dividends, combinations, splits, recapitalizations
and the like) plus accrued and unpaid dividends with respect to such shares. The
total amount to be paid for the Series A Preferred is hereinafter referred to as
the "Series A Redemption Price." The number of shares of Series A Preferred that
the Corporation shall be required to redeem on any one Series A Redemption Date
shall be equal to the amount determined by dividing (A) the aggregate number of
shares of Series A Preferred outstanding immediately prior to the Series A
Redemption Date by (B) the number of remaining Series A Redemption Dates
(including the Series A Redemption Date to which such calculation applies).
Shares subject to redemption pursuant to this Section 4.5.5(a)(i) shall be
redeemed from each holder of Series A Preferred on a pro rata basis.

                                 (ii)    The holders of at least seventy-five
percent (75%) of the then outstanding shares of Series C Preferred, voting
together as a separate class, may require the Corporation, to the extent it may
lawfully do so, to redeem the Series C Preferred in three (3) equal annual
installments beginning on the seventh (7th) anniversary of the earliest Original
Issue Date of the Series C Preferred, and ending on three (3) years from such
first redemption date (each redemption date, a "Series C Redemption Date"). The
Corporation shall effect such redemptions on the applicable Series C Redemption
Date by paying in cash in exchange for the shares of Series C Preferred to be
redeemed a sum equal to the Original Issue Price per share of Series C Preferred
(as adjusted for any stock dividends, combinations, splits, recapitalizations
and the like) plus accrued and unpaid dividends with respect to such shares. The
total amount to be paid for the Series C Preferred is hereinafter referred to as
the "Series C Redemption Price." The number of shares of Series C Preferred that
the Corporation shall be required to redeem on any one Series C Redemption Date
shall be equal to the amount determined by dividing (i) the aggregate number of
shares of Series C Preferred outstanding immediately prior to the Series C
Redemption Date by (ii) the number of remaining Series C Redemption Dates
(including the Series C Redemption Date to which such calculation applies).
Shares subject to redemption pursuant to this Section 4.5.5(a)(ii) shall be
redeemed from each holder of Series C Preferred on a pro rata basis.





                                      -20-
<PAGE>   21
                                 (iii)   At least thirty (30) days but no more
than sixty (60) days prior to each of the first Series A Redemption Date and the
first Series C Redemption Date, the Corporation shall send a notice (each, a
"Redemption Notice") to all holders of Series A Preferred or Series C Preferred,
as the case may be, to be redeemed setting forth (A) the Series A Redemption
Price or Series C Redemption Price for the shares to be redeemed; and (B) the
place at which such holders may obtain payment of the Series A Redemption Price
or Series C Redemption Price upon surrender of their share certificates. If the
Corporation does not have sufficient funds legally available to redeem all
shares to be redeemed at a Series A Redemption Date or Series C Redemption Date
(including, if applicable, those to be redeemed at the option of the
Corporation), then it shall redeem such shares pro rata (based on the portion of
the aggregate Series A Redemption Price or Series C Redemption Price payable to
them) to the extent possible and shall redeem the remaining shares to be
redeemed as soon as sufficient funds are legally available.

                        (b)      On or prior to each Series A Redemption Date
and Series C Redemption Date, the Corporation shall deposit the Series A
Redemption Price or Series C Redemption Price, as the case may be, of all shares
to be redeemed with a bank or trust company having aggregate capital and surplus
in excess of $100,000,000, as a trust fund, with irrevocable instructions and
authority to the bank or trust company to pay, on and after such Series A
Redemption Date or Series C Redemption Date, the Series A Redemption Price or
Series C Redemption Price of the shares to their respective holders upon the
surrender of their share certificates. Any money deposited by the Corporation
pursuant to this Section 4.5.5(b) for the redemption of shares thereafter
converted into shares of Common Stock pursuant to Section 4.5.4 hereof no later
than the fifth (5th) day preceding the Series A Redemption Date or Series C
Redemption Date, as the case may be, shall be returned to the Corporation
forthwith upon such conversion. The balance of any funds deposited by the
Corporation pursuant to this Section 4.5.5(b) remaining unclaimed at the
expiration of one (1) year following such Series A Redemption Date or Series C
Redemption Date shall be returned to the Corporation promptly upon its written
request.

                        (c)      On or after each Series A Redemption Date or
Series C Redemption Date, each holder of shares of Series A Preferred or Series
C Preferred to be redeemed on such Series A Redemption Date or Series C
Redemption Date, as the case may be (such shares, the "Redeemable Shares"),
shall surrender such holder's certificates representing such holder's Redeemable
Shares to the Corporation in the manner and at the place designated in the
Redemption Notice, and thereupon the Series A Redemption Price or Series C
Redemption Price of such shares shall be payable to the order of the person
whose name appears on such certificate or certificates as the owner thereof and
each surrendered certificate




                                      -21-
<PAGE>   22
shall be canceled. In the event less than all the shares represented by such
certificates are redeemed, a new certificate shall be issued representing the
unredeemed shares. From and after each Series A Redemption Date or Series C
Redemption Date, as the case may be, unless there shall have been a default in
payment of the Series A Redemption Price or Series C Redemption Price or the
Corporation is unable to pay the Series A Redemption Price or Series C
Redemption Price due to not having sufficient legally available funds, all
rights of the holder of Redeemable Shares as holder of Series A Preferred or
Series C Preferred (except the right to receive the Series A Redemption Price or
Series C Redemption Price, as the case may be, without interest upon surrender
of their certificates), shall cease and terminate with respect to such
Redeemable Shares, provided that in the event that shares of Series A Preferred
or Series C Preferred are not redeemed due to a default in payment by the
Corporation or because the Corporation does not have sufficient legally
available funds, such shares of Series A Preferred or Series C Preferred shall
remain outstanding and shall be entitled to all of the rights and preferences
provided herein.

                        (d)      In the event of a call for redemption of any
shares of Series A Preferred or Series C Preferred, as the case may be, the
Conversion Rights (as defined in Section 4.5.4) for such Series A Preferred or
Series C Preferred, as the case may be, shall terminate as to the Redeemable
Shares at the close of business on the fifth (5th) day preceding the Series A
Redemption Date or Series C Redemption Date, unless default is made in payment
of the Series A Redemption Price or Series C Redemption Price.

               4.5.6    No Reissuance of Series A Preferred. No share or shares
of Series A Preferred acquired by the Corporation by reason of redemption,
purchase, conversion or otherwise shall be reissued.

         4.6   No Preemptive Rights.  Stockholders shall have no preemptive
rights except as granted by the Corporation pursuant to written agreements.

         4.7   Release of Directors from Liability. A director of the
Corporation shall not be personally liable to the Corporation or its
stockholders for monetary damages for any breach of fiduciary duty as a
director, except for liability (i) for any breach of the director's duty of
loyalty to the Corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the Delaware General Corporation Law, or (iv)
for any transaction from which the director derived an improper personal
benefit. If the Delaware General Corporation Law is amended after approval by
the stockholders of this Article V to authorize corporate action further
eliminating or limiting the personal liability of directors, then the liability
of a director




                                      -22-
<PAGE>   23
shall be eliminated or limited to the fullest extent permitted by the Delaware
General Corporation Law, as so amended.

         4.8   Repeal; Modification. Any repeal or modification of this Article
V shall only be prospective and shall not affect the rights under this Article V
in effect at the time of the alleged occurrence of any action or omission to act
giving rise to liability.

                                        V

         For the management of the business and for the conduct of the affairs
of the Corporation, and in further definition, limitation and regulation of the
powers of the Corporation, of its directors and of its stockholders or any class
thereof, as the case may be, and subject, in all cases, to the provisions of
this Certificate of Incorporation, it is further provided that:

         5.1   Management by Board. The management of the business and the
conduct of the affairs of the Corporation shall be vested in its Board of
Directors. The member of directors shall be fixed by the Board of Directors in
the manner provided in the Bylaws.

         5.2   Amendment, etc. of Bylaws. The Board of Directors may from time
to time make, amend, supplement or repeal the Bylaws, provided, however, that
the stockholders may change or repeal any Bylaws adopted by the Board of
Directors by the affirmative vote of the holders of a majority of the voting
power of all of the then outstanding shares of the capital stock of the
Corporation; and, provided further, that no amendment or supplement to the
Bylaws adopted by the Board of Directors shall vary or conflict with any
amendment or supplement thus adopted by the stockholders.

         5.3   Election of Directors. The directors of the Corporation need not
be elected by written ballot unless the Bylaws so provide.

                                       VI

         The Corporation reserves the right to amend, alter, change or repeal
any provision of this Certificate of Incorporation, in the manner now or
hereafter prescribed by statute, subject to the provisions of this Certificate
of Incorporation."

                            PROPERTY LEASING CONTRACT
                      ON OFFICE PREMISES AT HLIOARSMARI 15

1.   PARTIES TO THE LEASE:

     LESSOR: Miojan ehf., State Reg. No. 580294-3599, Hlioarsmari 17, 200
             Kopavogur, tel. 554-6664.

             110 Reykjavik, tel. 570-1900.

2.   DEFINITION OF THE LEASED PROPERTY:
The leased property consists of the second, third, and fourth floors of the
office building at Hlioarsmari 17, currently under construction, in the town of
Kopavogur. More specifically, it consists of 397 m(2) on the second floor,
property lot registered no. 02-02 by the Valuation Office of Iceland, 963 m(2)
on the third floor, property lots no. 03-01 and 03-02, and 550 m(2) on the
fourth floor, property lot no. 04-01. The total gross size of the leased
property is therefore 1,910 m(2) including a mezzanine floor and shared premises
of all lessees of the building. The premises are leased for the office
activities of Islensk erfoagreining ehf., and will be furnished as required by
the Lessee in accordance with Article 5 of this Contract. The parking area on
the site shall be shared with other lessees of the building. The Lessee may not
use the building for activities unrelated with those specified above, without
the prior consent of the Lessor. The Lessee may not use the interior part of the
joint property for his activities, or in any other way curtail the functional
value of this part of the building.

3.   LEASE PERIOD AND DATE OF DELIVERY:

     COMMENCEMENT OF LEASE PERIOD: 1 July 2000.
     END OF LEASE PERIOD: 30 June 2005.

The property shall be delivered, in a completed state, in four (4) stages as
follows:

<TABLE>
<S>                                         <C>
         Property lot no. 02-02             1 June 2000, along with the interior
                                            part of the joint property
         Property lot no. 03-01             15 June 2000
         Property lot no. 03-02             1 July 2000
         Property lot no. 04-01             15 July 2000
</TABLE>

The above dates of delivery are subject to the condition that all design shall
have been completed by 20 March 2000. As indicated above, the date of actual
commencement of the lease period is variable, in accordance with the date of
delivery of each property lot. The "joint commencement of the lease period",
however, is fixed at 1 July 2000 for the sake of convenience only and payments
are adjusted below in Article 4 of this Contract. In other respects this Leasing
Contract shall remain in effect for five years as described above, and shall be
terminated without notice from either party on 30 June 2005. The Lessee shall
have the right of first refusal to lease the property when the five-year period
has expired, in the event of continuing lease of the property (cf. Article 51 of
the Property Rental Act No. 36/1994), provided that a new leasing contract is
then made. If the Lessee wishes to exercise his rights of first refusal to lease
the property, he shall announce this in writing to the Lessor in a verifiable
manner at no later date than 31 March 2005. Should he not choose to do so, his
right of first refusal shall lapse (cf. Article 51 of the Property Rental Act).

4.   LEASE AMOUNTS, PAYMENTS, AND PLACE OF PAYMENT:

Value Added Tax shall be added to the rent, which shall be in the amount of ISK
1,871,800 (VAT not included) or ISK 2,330,391 (VAT included) per month, in
letters ISK two million three hundred and thirty thousand three hundred ninety
one 00/100, not including operating expenses as described in Article 7 of this
Contract. The rent is calculated on the basis of the consumer price index of 1
February 2000 (195.5 points) and shall be adjusted up or down every month, for
the first time on 1 August 2000. Rent for the period 1 July 2000 - 31 July


                                  LL/p. 1 of 4
<PAGE>   3
2000, ISK 1,871,800 plus VAT, shall be paid on signature of this Contract
together with a balancing amount due to different dates of delivery of the
units, calculated as 325 m(2) for one month or ISK 318,500 plus VAT. A total of
ISK 2,190,625 (VAT not included), or ISK 2,727,328 (VAT included), shall
therefore be paid on signature of the Contract. Rent shall thereafter be paid
monthly, one month at a time in advance, due on the first day of every month and
with a final due date on the fifth day of every month, for the first time on 1
August 2000. The rent shall be paid into the Lessor's checking account no.
1135-26-777 in the Savings Bank of Kopavogur.

5.   ALTERATIONS AND RETURN OF THE LEASED PROPERTY:

The Lessor shall deliver the leased property, including the joint property and
site, in a fully finished state. The Lessor will arrange to have interior
furnishings designed at his expense according to the Lessee's requirements.
Design work shall be done by the designer of the building in consultation with
the Lessee, and final plans shall be submitted to the Lessee for approval. The
Lessor shall deliver the leased property fully completed, as follows: Partition
walls shall be plastered and isolated with insulating wool, and reach to the
ceiling. Partitioned rooms shall be finished with doors of cherry wood and
window units in the interior walls with recessed blinds. The building shall be
delivered freshly painted on the inside in light colours, with wiring ducts
along the exterior walls and installed radiators on every floor. Installation
channels shall contain electrical cables, computer installations and telephone
wires, and be equipped with a normal number of electricity and computer sockets.
Ceilings on the 4th floor shall be panelled with material of the Lessor's
choice, but 2nd and 3rd floor ceilings shall be suspended system ceilings with
mounted work lamps. Work lamps (about 2x36W) shall be connected to electricity
and delivered with installed fluorescent bulbs. The number of lamps shall be
sufficient to provide adequate light for work. All floors shall be
linoleum-covered. Bathrooms and storage rooms for cleaning material and apparel
shall be installed on every floor, equipped with toilets, washbasins, doors,
flooring, and water taps. Fire alarm and security systems will be installed.
However, the Lessor is not required to deliver the leased property with a
reception desk, cooker, refrigerator, window blinds, shelves and similar items.
The joint property shall be fully functional and complete with elevator, doors,
hand rails, and linoleum chosen by the Lessor. The standard for the fully
finished leased property shall be the joint premises and property lot no. 03-02
at Hlioarsmari 17, the premises of the company Ban ehf., and property lot no.
02-02 in the same building which the Lessee has thoroughly inspected. The site
shall be paved with asphalt and fully finished as soon as possible, when the
thaw in the ground frost permits, no later than 15 July 2000. The interior of
the joint property, however, shall be delivered in a fully finished state on 1
June 2000. As regards the furnishing of the leased property, it shall be assumed
that the premises will be fully furnished for maximum utilisation regarding the
order of rooms on each floor so that the lessee will not face any limitations in
the number of rooms in order to satisfy the needs of the company whether in
respect of offices, storage rooms, conference rooms or open spaces. Should the
Lessee on the other hand decide that he wants e.g. more expensive flooring
material in certain spaces, more sophisticated kitchen furnishings, aluminium
installation channels etc, he shall then pay the resulting additional cost in
the form of higher rent or by a lump sum payment. All fixed furnishings
installed by the Lessee subsequent to delivery shall become the property of the
Lessor upon the end of the lease period or termination of this Contract without
special compensation. The Lessee has familiarised himself with other operations
conducted in the building. Markings relating to the operations of the Lessee
shall be installed in consultation with the owners of the building, and shall
not be in conflict with rules of the building and municipal regulations. The
leased property shall be returned at the end of the lease period along with all
appurtenances, in no worse condition than upon commencement thereof apart from
normal wear.

6.   MAINTENANCE OF THE LEASED PROPERTY:

The Lessee shall, at his own expense, arrange for all indoor maintenance, e.g.
flooring, appliances, and equipment. The Lessor shall arrange for all
maintenance of the site and the


                                  LL/p. 2 of 4
<PAGE>   4
exterior of the building, including pipe and drainage channels even if they may
be regarded as being located indoors.

7.   OPERATING EXPENSES:

The Lessee shall pay all operating expenses, including the expense incurred by
the use of water and electricity in the leased property, and heating expenses.
The Lessee shall pay electricity expenses according to a separate meter, but
heating expenses are included in a building fund which is calculated
proportionally at each time. The monthly contribution to this fund is estimated
at ISK 107,000 and will be collected each month by a building association
service of a bank or savings bank that will be chosen by the board of the
building's as yet unfounded house association. The Lessee's proportional
contribution to the house fund shall be 59.2%. The house fund also covers
cleaning, heating and electricity of the joint property, clearing of snow from
the parking area, garbage collection, cleaning of exterior windows, mowing of
the lawn and the like. The Lessor shall pay all property taxes, and all expenses
incurred by renovation of the exterior of the building, joint property or
outlying premises.

8.   RIGHTS AND OBLIGATIONS:

The Lessee shall treat the leased property in every way consistent with
generally accepted principles regarding such treatment. The Lessor shall, in
consultation with the Lessee, have the right of access to the leased property
for the purposes of conducting improvements on the building or showing it to
prospective lessees/buyers, provided that he gives reasonable notice of any
intent to exercise this right.

9.   SALE AND SUBLETTING OF THE LEASED PROPERTY:

Sale of the leased property is not subject to approval of the Lessee. Upon sale,
the Lessor shall surrender his ownership to the leased property to the buyer,
who will in every regard replace the Lessor as of an agreed date of delivery of
the property. They buyer will assume all rights and duties of the Lessor,
whereas the rights and duties of the Lessee remain unaltered. The Lessor shall
inform the Lessee of the sale of the property in a verifiable manner within 30
days of signing a purchase contract. The Lessee may, partially or entirely,
sublet the leased property to a third party conducting similar operations,
subject however to the Lessor's written consent.

10.  INSURANCE AND LIABILITY

The Lessee undertakes to take out insurance with a recognised insurance company,
covering damage to the furnishings from water, fire, etc. The Lessor shall
purchase homeowner's insurance for the leased property itself. The Lessor is not
responsible for damage that may occur to the Lessee's property in the leased
property from accidents such as water damage, fire, smoke etc., except damage
unlawfully caused by the Lessor himself or people for which he is responsible.
The Lessee exercise care regarding fire in the building and ensure that there is
no fire hazard from electrical cables, machines, and other things that he keeps
and uses in the building. The Lessor shall ensure that upon delivery the leased
property complies with fire safety regulations regarding office buildings.
Subsequent to delivery, however, the Lessee shall at his own expense arrange for
all necessary fire safety measures in the leased property, which may be required
by the Reykjavik Fire Authority due to the operations conducted by the Lessee or
alterations that he may have done to the leased property. The Lessor's liability
for damage which the Lessee may suffer will in other respects be determined by
general rules on compensation.

11.  DEFAULT

Remedies available to the Lessor in case of default on the part of the Lessee
shall be determined by the provisions of the Property Rental Act no. 36/1994.
All expenses incurred by clearing the building, and moving and storing the
Lessee's property shall be paid by the Lessee. Penalty interest of the rent
amount shall be calculated according to the postings of the


                                  LL/p. 3 of 4
<PAGE>   5
Central Bank of Iceland from the date that payment was due, if rent is not paid
on the final due date.

12.  GUARANTEE

To ensure performance of this Leasing Contract the Lessee submits a bank
guarantee to the amount of ISK 11,230,800, the equivalent of six month's rent
(VAT not included). The bank guarantee shall remain valid until 31 August 2005,
and the Lessor shall draw funds from it to compensate for any non-performance or
damage to the building which may occur before that date. Should default occur in
payment of the rent (cf. Article 11 above) and collecting measures fail, the
Lessor may draw on the bank guarantee for payment of the rent amount owed by the
Lessee. In other respects the bank guarantee is for the purpose of compensating
for damage to the building for which the Lessee is responsible. However, in the
event of damage to the building, the Lessor may not draw on the bank guarantee
before a court of law has ruled on the Lessee's obligation to pay. By signing
this Leasing Contract the Lessor confirms reception of the aforesaid banker's
guarantee to the amount of ISK 11,230,800 (VAT not included), and of the payment
of rent to the amount of ISK 2,727,328 (VAT included) i.e. for the period from

in each case subject to no mortgage, pledge, lien, lease, encumbrance or charge,

properties owned, leased or used by the Company are in good operating condition
and repair and are reasonably fit and usable for the purposes for which they are
being used. Each lease of real or personal property to which the Company is a
party is fully effective, affords the Company peaceful and undisturbed
possession of the subject matter of the lease and is free of any liens, claims
or encumbrances. To the knowledge of the Company (except with respect to its own
obligations and enforceability against itself), each such lease constitutes a
valid and binding obligation of, and

<PAGE>   15
is enforceable in accordance with its terms against, the respective parties
thereto.

possesses sufficient legal rights to all patents, trademarks, service marks,
trade names, copyrights, trade secrets, information and other proprietary rights
and processes necessary for its business as now conducted and as proposed to be
conducted (such rights as the Company owns or has a license to, collectively,
the "Intellectual Property Rights"), without any known infringement of the
rights of others. To the Company's knowledge, the Intellectual Property Rights
are valid and enforceable. There are no outstanding options, licenses or
agreements of any kind relating to the Intellectual Property Rights, nor is the
Company bound by or a party to any options, licenses or agreements of any kind
with respect to the patents, trademarks, service marks, trade names, copyrights,
trade secrets, licenses, information and other proprietary rights and processes
of any other person or entity other than such licenses or agreements arising
from the purchase of "off the shelf" or standard products. The Company has not
received any communications alleging that the Company has violated or, by
conducting its business as proposed would violate, any of the patents,
trademarks, service marks, trade names, copyrights or trade secrets or other
proprietary rights of any other person or entity, nor is the Company aware of
any basis for any such claim. To the Company's knowledge, no person, corporation
or other entity is infringing any of the Intellectual Property Rights. The
Company is not aware that any of its employees is obligated under any contract
(including licenses, covenants or commitments of any nature) or other agreement,
or subject to any judgment, decree or order of any court or administrative
agency, that would interfere with their duties to the Company or that would
conflict with the Company's business as conducted or proposed to be conducted.
Neither the execution nor the delivery of this Agreement, nor the carrying on of
the Company's business as proposed will, to the Company's knowledge, conflict
with or result in a breach of the terms, conditions or provisions of, or
constitute a default under, any contract, covenant or instrument under which any
employee of the Company is now obligated. The Company does not believe that it
is or will be necessary to utilize any inventions, trade secrets or proprietary
information of any of its employees made prior to their employment by the
Company, except for inventions, trade secrets or proprietary information that
have been assigned to the Company. The Company has no obligation to compensate
others for use of any of the Intellectual Property Rights, nor has the Company
granted any license or other right to use, in any manner, any of the
Intellectual Property Rights, whether or not requiring the payment of royalties.

         3.11     Compliance with Other Instruments. The Company is not in
violation or default of any term of its certificate of incorporation as in
effect as of the date hereof, or its Bylaws or, to the knowledge of the Company,
of any provision of any mortgage, indenture, contract, agreement, instrument or
contract to which it is party or by which it is bound or of any judgment,
decree, order, writ or, to its knowledge, any statue, rule or regulation
applicable to the Company which would materially and adversely affect the
business, assets, liabilities, financial condition, operations or prospects of
the Company, and will not be in violation or default of any term of the Amended
Certificate of Incorporation, when such Certificate is filed. The execution,

Rights Agreement, and the issuance and sale of the Shares and the Warrants
pursuant hereto, the issuance of the Warrant Shares upon the exercise of the
Warrants, and the issuance of the Conversion Shares pursuant to the Amended
Certificate of Incorporation, will not, with or without the passage of time or
the giving of notice, result in any such material violation, or be in conflict
with or constitute a default under any such term, or result in the creation of
any mortgage, pledge, lien, encumbrance or charge upon any of the properties or
assets of the Company or the suspension, revocation, impairment, forfeiture or
non-renewal of any permit license, authorization or approval applicable to the
Company, its business or operations or any of its assets or properties.

         3.12     Litigation. There is no action, suit, proceeding or
investigation pending or, to the Company's knowledge, currently threatened
against the Company that questions the validity of this Agreement, or the
Investor Rights Agreement or the right of the Company to enter into any of such
agreements, or to consummate the transactions contemplated hereby or thereby, or
which might result, either individually or in the aggregate, in any material
adverse change in the assets, condition, affairs or prospects of the Company,
financially or otherwise, nor is the Company aware that there is any basis for
the foregoing. The foregoing includes, without limitation, actions pending or
threatened (or any basis therefor known to the Company) involving the prior
employment of any of the Company's employees, their use in connection with the
Company's business of any information or techniques allegedly proprietary to any
of their former employers, or their obligations under any agreements with prior
employers. The Company is not a party or subject to the provisions of any order,
writ, injunction, judgment or decree of any court or government agency or
instrumentality. There is no action, suit, proceeding or investigation by the
Company currently pending or which the Company intends to initiate.

         3.13     Employees. The Company has no collective bargaining agreements
with any of its employees. There is no labor union organizing activity pending
or, to the Company's knowledge, threatened with respect to the Company. To the
Company's knowledge, no employee of the Company, nor any consultant with whom
the Company has contracted, is in violation of any term of any employment
contract, proprietary information agreement or any other agreement relating to
the right of any such individual to be employed by, or to contract with, the
Company because of the nature of the business to be conducted by the Company;
and to the Company's knowledge, the continued employment by the Company of its
present employees, and the performance of the Company's contracts with its
independent contractors, will not result in any such violation. The Company has
not received any notice alleging that any such violation has occurred. The
Company is not aware that any officer or key employee, or that any group of key
employees, intends to terminate their employment with the Company, nor does the
Company have a present intention to terminate the employment of any officer, key
employee or group of key employees.

         3.14     Proprietary Information and Inventions Agreement. Each current
employee, officer and consultant of the Company has executed a Proprietary
Information and Inventions Agreement in the form of Exhibit H attached.

         3.15     Compliance with Laws; Permits. To its knowledge, the Company
is not in violation of any applicable statute, rule, regulation, order or
restriction of any domestic or foreign government or any instrumentality or
agency thereof in respect of the conduct of its business or the ownership of its
properties which violation would materially and adversely affect the business,
assets, liabilities, financial condition, operations or prospects of the
Company. No governmental orders, permissions, consents, approvals or
authorizations are required to be obtained, and no registrations or declarations
are required to be filed, in connection with the execution and delivery of this
Agreement and the issuance of the Shares, the Warrant Shares or the Conversion
Shares, except such as has been duly and validly obtained or filed, or with
respect to any filings that must be made after the Closing(s), as will be filed
in a timely manner. The Company has all franchises, permits, licenses and any
similar authority necessary for the conduct of its business as now being
conducted by it, the lack of which could materially and adversely affect the
business, properties, prospects or financial condition of the Company and
believes it can obtain, without undue burden or expense, any similar authority
for the conduct of its business as planned to be conducted.

requirements of all applicable securities laws of any state of the United
States. Neither the Company nor any agent on its behalf has solicited or will
solicit any offers to sell or has offered to sell or will offer to sell all or
any part of the Shares or Warrants to any person or persons so as to bring the
sale of such Shares or Warrants by the Company within the registration
provisions of the Securities Act.

         3.18     Full Disclosure. This Agreement, the Exhibits hereto, the
Investor Rights Agreement and all other documents delivered by the Company to
the Purchaser or its attorneys or agents in connection herewith or therewith or
with the transactions contemplated hereby or thereby, do not contain any untrue
statement of a material fact nor, to the Company's knowledge, omit to state a
material fact necessary in order to make the statements contained herein or
therein not misleading. Notwithstanding the foregoing, any Business Plan (a
"Business Plan") provided to the Purchaser was prepared by the management of the
Company in a good faith effort to describe the Company's proposed business and
products and the markets therefor. The assumptions applied in preparing any
Business Plan appeared reasonable to management as of the date thereof; however,
there is no assurance that these assumptions will prove to be valid or that the
objectives set forth in the Business Plan will be achieved. To the Company's
knowledge, there are no facts which (individually or in the aggregate)
materially adversely affect the business, assets, liabilities, financial
condition, prospects or operations of the Company that have not been set forth
in this Agreement, the Exhibits hereto, the Investor Rights Agreement or in
other documents delivered to the Purchaser or its attorneys or agents in
connection herewith.

Warrants and the Warrant Shares shall be used by the Company for general
corporate purposes, including research and development.

the time prescribed by law all federal, state and local income, excise or

by it, and has paid or made provision for the payment of all accrued and unpaid
taxes and other charges to which the Company is subject and which are not
currently due and payable. The Company has not elected to be treated as a
Subchapter S corporation pursuant to Section 1362 of the Code or as a
collapsible corporation pursuant to Section 341(f) of the Code. The Company has
never had any tax deficiency proposed or assessed against it and has not
executed any waiver of any statute of limitations on the assessment or
collection of any tax or governmental charge. The United States federal income
tax returns of the Company have never been audited by the United States Internal
Revenue Service (the "IRS"). Neither the IRS nor any other taxing authority is
now asserting or is threatening to assert against the Company any deficiency or
claim for additional taxes or interest thereon or penalties in connection
therewith, and the Company does not know of any such deficiency or any basis for
any such deficiency or claim.

defined benefit or defined contribution plans of the Company, if any, for its
employees that are subject to the United States Employee Retirement Income
Security Act of 1974, as amended ("ERISA"). The Company is in compliance in all
respects with all material provisions of ERISA to the extent the Company's
pension,


                                       17
<PAGE>   21
defined benefit or defined contribution plans, if any, are subject to ERISA.

         3.26     Issuance of Series B Preferred. The Company shall not issue

per-share basis, is less than the per-share purchase price last paid by the

IPO obtained by dividing US$2,000,000 by the IPO per share price, subject to the
approval of the lead underwriter.

         3.28     Future Issuance of Common Stock. The Company shall reserve

4.       REPRESENTATIONS AND WARRANTIES OF PURCHASER.

         The Purchaser hereby represents and warrants to the Company, as of the
date of this Agreement, as follows (such representations and warranties not
lessening or obviating the representations or warranties of the Company set
forth in this Agreement):

         4.1      Requisite Power and Authority. All corporate action on the
part of the Purchaser, its officers, directors and stockholders, necessary for
the authorization of this Agreement and the Investor Rights Agreement, the
performance of all obligations of the Purchaser hereunder and thereunder at each
Closing and the purchase of the Shares and the Warrants pursuant to this
Agreement, have been or will be effectively taken prior to the First Closing.
Upon their execution and delivery, this Agreement and the Investor Rights
Agreement will be valid and binding obligations of the Purchaser, enforceable in
accordance with their terms, except (i) as limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other laws of general application
affecting enforcement of creditors' rights, and general principles of equity
that restrict the availability of equitable remedies, and (ii) to the extent
that the enforceability of the indemnification


                                       18
<PAGE>   22
provisions of Section 2.10 of the Investor Rights Agreement may be limited by
applicable laws.

         4.2      Investment Representations. The Purchaser understands that
neither the Shares, the Warrants, the Warrant Shares nor the Conversion Shares
have been registered under the Securities Act. The Purchaser also understands
that the Shares and the Warrants are being offered and sold pursuant to an
exemption from registration contained in the Securities Act based in part upon
the Purchaser's representations contained in this Agreement. The Purchaser
hereby represents and warrants as follows:

                  (a) The Purchaser is an entity organized and existing under
the laws of Switzerland, is not a "U.S. person" (as such term is defined in
Regulation S promulgated under the Securities Act ("Regulation S")), and was not
formed by a "U.S. person" principally for the purpose of investing in securities
not registered under the Securities Act.

                  (b) The Purchaser has substantial experience in evaluating and
investing in private placement transactions of securities in companies similar
to the Company so that it is capable of evaluating the merits and risks of its
investment in the Company and has the capacity to protect its own interests. The
Purchaser must bear the economic risk of this investment indefinitely unless the
Shares and Warrants (or the Conversion Shares or Warrant Shares, as the case may
be) are registered pursuant to the Securities Act or an exemption from such
registration is available. The Purchaser understands that the Company has no
present intention of registering the Shares, the Warrants, the Warrant Shares,
the Conversion Shares or any shares of its Common Stock. The Purchaser also
understands that there is no assurance that any exemption from registration
under the Securities Act will be available and that, even if available, such
exemption may not allow the Purchaser to transfer all or any portion of the
Shares, Warrants, Warrant Shares or the Conversion Shares under the
circumstances, in the amounts or at the times the Purchaser might propose.

                  (c) The Purchaser is acquiring the Shares, the Warrants and
the Conversion Shares for the Purchaser's own account, for investment only, and
not with a view toward their distribution. The Purchase is not acquiring the
Shares, the Warrants or the Conversion Shares for the account or benefit of any
U.S. person (as such term is defined in Regulation S).

                  (d) The Purchaser represents that by reason of its or of its
management's business or financial experience, the Purchaser has the capacity to
protect its own interests in


                                       19
<PAGE>   23
connection with the transactions contemplated in this Agreement, and the
Investor Rights Agreement.

                  (e) The Purchaser represents that it is an "accredited
investor" within the meaning of Regulation D promulgated under the Securities
Act.

                  (f) The Purchaser has received and read the Financial
Statements and Business Plans and has had an opportunity to discuss the
Company's business, management and financial affairs with directors, officers
and management of the Company and has had the opportunity to review the
Company's operations and facilities. The Purchaser has also had the opportunity
to ask questions of, and receive answers from, the Company and its management
regarding the terms and conditions of this investment. The Purchaser has had an
opportunity to obtain any additional information, to the extent that the Company
possesses such information, or can acquire it without unreasonable effort or
expense, necessary to verify the accuracy of the information given to the
Purchaser.

                  (g) The Purchaser acknowledges and agrees that the Shares and
Warrants, and, if issued, the Warrants Shares and Conversion Shares, must be
held indefinitely unless they are subsequently registered under the Securities
Act, an exemption from such registration is available or as otherwise permitted
by applicable United States federal or state law. The Purchaser has been advised
or is aware of the provisions of Rule 144 promulgated under the Securities Act,
which permits limited resale of shares purchased in a private placement subject
to the satisfaction of certain conditions, including, among other things: the
availability of certain current public information about the Company, the resale
occurring not less than one (1) year after a party has purchased and paid for
the security to be sold, the sale being through an unsolicited "broker's
transaction" or in transactions directly with a market maker (as said term is
defined under the United States Securities Exchange Act of 1934, as amended) and
the number of shares being sold during any three-month period not exceeding
specified limitations.

                  (h) The Purchaser acknowledges and agrees that each
certificate representing the Shares, Warrants, Warrant Shares and the Conversion
Shares shall bear, in addition to the legend set forth in Section 2.1(b) of the
Investor Rights Agreement, substantially the following legends (in addition to
any legends required under applicable United States state securities laws):

        THE SECURITIES EVIDENCED BY THIS CERTIFICATE MAY NOT BE
        OFFERED, SOLD OR TRANSFERRED IN THE UNITED STATES OR TO
        U.S.PERSONS UNTIL REGISTERED UNDER THE ACT OR UNLESS THE


                                       20
<PAGE>   24
        COMPANY HAS RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE
        COMPANY AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT
        REQUIRED.

        TRANSFER OF THE SECURITIES EVIDENCED BY THIS CERTIFICATE IS
        PROHIBITED EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF
        REGULATION S PROMULGATED PURSUANT TO THE ACT.

         4.3      Transfer Restrictions.

                  (a) The Purchaser acknowledges and agrees that the Shares and
the Warrants and, if issued, the Warrant Shares and the Conversion Shares are
subject to restrictions on transfer as set forth in the Investor Rights
Agreement and in this Agreement.

                  (b) The Purchaser agrees to resell the Shares and Warrants
and, if issued, the Warrant Shares and Conversion Shares, only in accordance
with the provisions of Regulation S, or pursuant to registration under the
Securities Act or to an exemption from such registration. Furthermore, the
Purchaser acknowledges and agrees that the Company shall refuse to register any
transfer of the Shares or Warrants or, if issued, the Warrant Shares or
Conversion Shares, not made in accordance with the provisions of Regulation S.

                              deCODE GENETICS, INC.

                        FOUNDER STOCK PURCHASE AGREEMENT

THIS AGREEMENT is made as of the 21st day of August, 1996 by and between deCODE
GENETICS, INC., a Delaware corporation (the "Corporation"), and JEFFREY R.
GULCHER (the "Purchaser").

         WHEREAS, pursuant to Section 152 of the Delaware General Corporation
Law, the Corporation desires to issue, and the Purchaser desires to acquire,
stock of the Corporation as herein described, on the terms and conditions
hereinafter set forth:

         WHEREAS, the issuance of Common Stock hereby is, where applicable, in
connection with a compensatory benefit plan for the employees, directors,
officers, advisers or consultants of the Corporation and is intended to comply
with the provisions of Rule 701 promulgated by the Securities and Exchange
Commission (the "SEC") under the Securities Act of 1933, as amended (the "Act").

         NOW, THEREFORE, IT IS AGREED between the parties as follows:

         1. The Purchaser hereby agrees to purchase from the Corporation, and
the Corporation hereby agrees to sell to the Purchaser, an aggregate of Four
Hundred Eighty One Thousand Two Hundred (481,200) shares of the Common Stock of
the Corporation (the "Stock") at one tenth of one cent ($.001) per share, for an
aggregate purchase price of $481.200, which amount shall be payable in cash.

         2. The shares to be purchased by the Purchaser pursuant to this
Agreement (hereinafter sometimes collectively referred to as the "Stock") shall
be subject to the repurchase options of the Corporation set forth in
subparagraphs (a) and (b) below ("Purchase Option"):


                                       1.
<PAGE>   2
                  (a) In the event the Purchaser ceases to be an employee of the
Corporation as a result of (1) voluntary or mutual termination of Purchaser's
employment (except as a result of bona fide medical disability); or (2)
termination of Purchaser's employment by the Company for any of the following
reasons: (A) indictment or conviction of any felony or of any crime involving
dishonesty; (B) participation in any fraud against the Company; (C) breach of
Purchaser's duties to the Company, including, without limitation, persistent
unsatisfactory performance of job duties or breach of loyalty (except as a
result of bona fide medical disability); (D) intentional damage to any Company
property; or (E) conduct by Purchaser which in the good faith and reasonable
determination of the Board demonstrates gross unfitness to serve, the
Corporation shall have the right as set forth herein, to exercise its Purchase
Option. The Corporation may, by exercising its Purchase Option at any time
within ninety (90) business days after said cessation or such longer period as
may be determined by the Company if such later repurchase is deemed necessary by
the Company for treatment of its stock as Qualified Small Business Stock under
Section 1202 of the Internal Revenue Code of 1986, as amended and regulations
promulgated thereunder, repurchase from the Purchaser or his personal
representative, as the case my be, at the total price per share indicated above
as paid by the Purchaser for such Stock ("Option Price"), up to but not
exceeding the number of shares of stock which have not vested under the
provisions of paragraph (b) below. As used herein, employment with the
Corporation shall include employment with a "parent" or "subsidiary" of the
Corporation as those terms are defined in Sections 424(e) and (f) of the
Internal Revenue Code of 1986, as amended.

                  (b) The right of the Corporation to exercise its Purchase
Option as to the maximum portion of the stock specified in the event of
termination shall be by reference to the following schedule.


                                       2.
<PAGE>   3
                  (i) 10% of the stock issued to the Purchaser shall vest as of
the date of this Agreement; and

                  (ii) 1.875% of the stock issued to the Purchaser shall vest
monthly thereafter.

            (c) The Corporation shall be entitled to pay for any shares
purchased pursuant to it Purchase Option at the Corporation's option in cash or
by offset against any indebtedness owing to the Corporation by Purchaser
(including without limitation any Note given in payment for the Stock).

            (d) Nothing in this Agreement shall affect in any manner whatsoever
the right or power of the Corporation (or a parent or subsidiary of the
Corporation) to terminate Purchaser's employment.

         3. The Purchase Option shall be exercised by written notice signed by
an officer of the Corporation or by any assignee or assignees of the Corporation
and delivered or mailed as provided in paragraph 13. Such notice shall identify
the number of shares to be purchased and shall notify the Purchaser of the time,
place and date for settlement of such purchase, which shall be scheduled by the
Corporation within one hundred fifty (150) business days from the date of
cessation of employment.

         4. If, from time to time during the term of the Purchase Option:

                  (i) There is any stock dividend or other distribution of cash
and/or property, stock split or other change in the character or amount of any
of the outstanding securities of the Corporation; or

                  (ii) There is any consolidation, merger or sale of all, or
substantially all of the assets of the Corporation;


                                       3.
<PAGE>   4
then, in such event, any and all new, substituted or additional securities or
other property to which the Purchaser is entitled by reason of its ownership of
Stock shall be immediately subject to the Purchase Option and be included in the
word "Stock" for all purposes of the Purchase Option with the same force and
effect as the shares of the Stock presently subject to the Purchase Option.
While the total Option Price shall remain the same after each such event, the
Option Price per share of Stock upon exercise of the Purchase Option shall be
appropriately adjusted.

         Upon the occurrence of any event specified in clause (ii) above, the
Purchase Option may be assigned to any successor to the Corporation, and the
Purchase Option shall apply if the Purchaser does not become or shall cease for
any reason to be employed by such successor (or its parent or subsidiaries). In
such case, the references herein to the "Corporation" shall be deemed to refer
to such successor.

         5. All certificates representing any shares of Stock of the Corporation
subject to the provisions of this Agreement shall have endorsed thereon legends
in substantially the following forms (in addition to any other legend which may
be required by other agreements between the parties hereto):

                  (i) "The shares represented by this certificate are subject to
an option set forth in an agreement between the Corporation and the registered
holder, or his predecessor in interest, a copy of which is on file at the
principal office of the Corporation. Any transfer or attempted transfer of any
shares subject to such option is void without the prior express written consent
of the issuer of these shares."

                  (ii) "The securities represented by this Certificate have not
been registered under the Securities Act of 1933. They may not be sold, offered
for sale, pledged or hypothecated in the absence of an effective registration
statement as to the securities under



                                       4.
<PAGE>   5
said Act or an opinion of counsel satisfactory to the Company that such
registration is not required."

                  (iii) "The shares represented by this certificate are subject
to a right of first refusal option in favor of the corporation and/or its
assignee(s) as provided in the bylaws of the Corporation."

                  (iv) Any legend required by applicable state securities laws.

         6. Purchaser acknowledges that he is aware that the Stock to be issued
to him by the Corporation pursuant to this Agreement has not been registered
under the Act, and that the Stock is deemed to constitute "restricted
securities" under Rule 701 and Rule 144 promulgated under the Act. In this
connection, Purchaser warrants and represents to the Corporation that Purchaser
is purchasing the Stock Purchaser's own account and Purchaser has no present
intention of distributing or selling said stock except as permitted under the
Act and under applicable state securities laws. Purchaser further warrants and
represents that Purchaser has either (i) preexisting personal or business
relationships with the Corporation or any of its officers, directors or
controlling persons, or (ii) the capacity to protect his own interests in
connection with the purchase of the Stock by virtue of the business or financial
expertise of himself or of professional advisors to the Purchaser who are
unaffiliated with and who are not compensated by the Corporation or any of its
affiliates, directly or indirectly. Purchaser further acknowledges that the
exemption from registration under Rule 144 will not be available for at least
three years from the date of sale of the Stock unless at least two years from
the date of sale (i) a public trading market then exists for the Common Stock of
the Corporation, (ii) adequate information concerning the Corporation is then
available to the public, and (iii) other terms and conditions of Rule 144 are
complied with; and that any sale of the Stock may be made only in limited
amounts in accordance with such terms and conditions and that exemption from
registration


                                       5.
<PAGE>   6
under Rule 701 will not be available until ninety days after the Corporation
becomes subject to the reporting requirements of Section 13 or 15(d) of the
Securities Exchange Act of 1934 and that after such date the Stock may be resold
by persons other than affiliates in reliance on Rule 144 without compliance with
paragraphs (c), (d), (e) and (h) thereof, and by affiliates without compliance
with paragraph (d) thereof.

         7. The Purchaser agrees that during the one hundred eighty (180) day
period following the effective date of a registration statement of the
Corporation filed under the Act of the Purchaser shall not, to the extent
requested by the Corporation and any underwriter, sell or otherwise transfer or
dispose of (other than to donees who agree to be similarly bound), or enter into
any hedging or similar transaction with the same economic effect as a sale, any
Common Stock of the Corporation held by the Purchaser at any time during such
period (the "Purchaser's Registrable Securities") except Common Stock included
in such registration; provided, however, that:

                  (a) such agreement shall be applicable only to the first such
registration statement of the Corporation which covers Common Stock (or other
securities) to be sold on its behalf to the public in an underwritten offering;
and

                  (b) all officers and directors of the Corporation enter into
similar agreements. In order to enforce the foregoing covenant, the Corporation
may impose stop-transfer instructions with respect to the Purchaser's
Registrable Securities (and the shares or securities of every other person
subject to the foregoing restriction) until the end of such period.

         8. The Purchaser shall not transfer by sale, assignment, hypothecation,
donation or otherwise any of the Stock or any interest therein subject to the
Purchase Option without the prior express written consent of the issuer of the
shares. As security for his faithful performance of the terms of this Agreement
and to insure the availability for delivery of Purchaser's Stock



                                       6.
<PAGE>   7
upon exercise of the Purchase Option herein provided for, the Purchaser agrees,
at the closing hereunder, to deliver to and deposit with the Secretary of the
Corporation ("Escrow Agent"), as Escrow Agent in this transaction, three stock
assignments duly endorsed (with date and number of shares blank) in the form
attached hereto as Exhibit B, together with a certificate or certificates
evidencing all of the Stock subject to the Purchase Option; said documents are
to be held by the Escrow Agent and delivered by said Escrow Agent pursuant to
the Joint Escrow Instructions of the Corporation and the Purchaser set forth in
Exhibit A attached hereto and incorporated by this reference, which instructions
shall also be delivered to the Escrow Agent at the closing hereunder.

         9. The Corporation shall not be required (i) to transfer on its books
any shares of Stock of the Corporation which shall have been transferred in
violation of any of the provisions set forth in this Agreement or (ii) to treat
as owner of such shares or to accord the right to vote as such owner or to pay
dividends to any transferee to whom such shares shall have been so transferred.

         10. Subject to provisions of paragraphs 7, 8, and 9 above, the
Purchaser (but not any unapproved transferee) shall exercise all rights and
privileges of a shareholder of the Corporation with respect to the Stock.

         11. Paragraphs 2, 3 and 4 of this Agreement shall terminate upon the
exercise in full or expiration of the Purchase Option, whichever first occurs.

         12. The parties agree to execute such further instruments and to take
such further action as may reasonably be necessary to carry out the intent of
this Agreement.

         13. Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon personal delivery or upon
deposit in the United States Post Office, by registered or certified mail with
postage and fees prepaid, addressed to the other party


                                       7.
<PAGE>   8
hereto at his address hereinafter shown below its signature or at such other
address as such party may designate by ten (10) days advance written notice to
the other party hereto.

         14. This Agreement shall inure to the benefit of the successors and
assigns of the Corporation and, subject to the restrictions on transfer herein
set forth, be binding upon the Purchaser, its successors, and assigns. The
Purchase Option of the Corporation hereunder shall be assignable by the
Corporation at any time or from time to time, in whole or in part.

         15. The Purchaser shall reimburse the Corporation for all costs
incurred by the Corporation in enforcing the performance of, or protecting its
rights under, any part of this Agreement, including reasonable costs of
investigation and attorney's fees. It is the intention of the parties that the
Corporation, upon exercise of the Purchase Option and payment of the Option
Price, pursuant to the terms of this Agreement, shall be entitled to receive the
Stock, in specie, in order to have such Stock available for future issuance
without dilution of the holdings of other shareholders. Furthermore, it is
expressly agreed between the parties that money damages are inadequate to
compensate the Corporation for the Stock and that the Corporation shall, upon
proper exercise of the Purchase Option, be entitled to specific enforcement of
its rights to purchase and receive said Stock.

         16. This Agreement shall be governed by and construed in accordance
with the laws of the State of Delaware. The parties agree that any action
brought by either party to interpret or enforce any provision of this Agreement
shall be brought in, and each party agrees to, and does hereby, submit to the
jurisdiction and venue of, the appropriate state or federal court for the
district encompassing the Corporation's principal place of business.

         17. The parties agree to take all such further action(s) as may
reasonably be necessary to carry out and consummate this Agreement as soon as
practicable, and to take whatever steps may be necessary to obtain any
governmental approval in connection with or otherwise qualify



                                       8.

the issuance of the securities that are the subject of this Agreement. The
closing hereunder, including payment for and delivery of the Stock, shall occur
at the offices of Cooley Godward Castro Huddleson & Tatum in Palo Alto,
California on the date hereof, or at such other time and place as the parties
may mutually agree.

         18. This Agreement is not an employment contract and nothing in this
Agreement shall be deemed to create in any way whatsoever any obligations on the
part of the Purchaser to continue in the employ of the Corporation or of the
Corporation to continue the Purchaser in the employ of the Corporation.

         19. Purchaser acknowledges that this Agreement has been prepared on
behalf of the Company by Cooley Godward Castro Huddleson & Tatum, counsel to the
Company and that Cooley Godward does not represent, and is not acting on behalf
of, Purchaser. Purchaser has been provided with an opportunity to consult with
its own counsel with respect to this Agreement.

         20. This Agreement constitutes the entire agreement between the parties
with respect to the subject matter hereof. This Agreement may not be amended,
modified or revoked, in whole or in part, except by an agreement in writing
signed by each of the parties hereto.

Dear Sir:

         As Escrow Agent for both deCODE genetics, Inc., a Delaware corporation
("Corporation"), and Jeffrey R. Gulcher ("Purchaser"), you are hereby authorized
and directed to hold the documents delivered to you pursuant to the terms of
that certain Stock Purchase Agreement ("Agreement") dated as of August 21, 1996,
to which a copy of these Joint Escrow Instructions is attached as EXHIBIT A, in
accordance with the following instructions:

         1. In the event Corporation or an assignee shall elect to exercise the
Purchase Option set forth in the Agreement, the Corporation or its assignee will
give to Purchaser and you a written notice specifying the number of shares of
stock to be purchased, the purchase price, and the time for a closing thereunder
at the principal office of the Corporation. Purchaser and the Corporation hereby
irrevocably authorize and direct you to close the transaction contemplated by
such notice in accordance with the terms of said notice.

         2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver the same, together with the certificate
evidencing the shares of stock to be transferred, to the Corporation against the
simultaneous delivery to you of the purchase price (which may include suitable
acknowledgment of cancellation of indebtedness) for the number of shares of
stock being purchased pursuant to the exercise of the Purchase Option.

         3. Purchaser irrevocably authorizes the Corporation to deposit with any
certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as specified in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as his
attorney-in-fact and agent for the term of this escrow to execute with respect
to such securities all documents necessary or appropriate to make such
securities negotiable and complete any transaction herein contemplated,
including but not limited to any appropriate filing with state or government
officials or bank officials. Subject to the provisions of this paragraph 3,
Purchaser shall exercise all rights and privileges of a shareholder of the
Corporation while the stock is held by you.


                                       1.
<PAGE>   12
         4. This escrow shall terminate upon the exercise in full or expiration
of the Purchase Option, whichever occurs first.

         5. If at the time of termination of this escrow you should have in your
possession any documents, securities, or other property belonging to Purchaser,
you shall deliver all of the same to Purchaser and shall be discharged of all
further obligations hereunder; provided, however, that if at the time of
termination of this escrow you are advised by the Corporation that any property
subject to this escrow is the subject of a pledge or other security agreement,
you shall deliver all such property to the pledgeholder or other person
designated by the Corporation.

         6. Your duties hereunder may be altered, amended, modified or revoked
only by a writing signed by all of the parties hereto.

         7. You shall be obligated only for the performance of such duties as
are specifically set forth herein and may rely and shall be protected in relying
or refraining from acting on any instrument reasonable believed by you to be
genuine and to have been signed or presented by the proper party or parties. You
shall not be personally liable for any act you may do or omit to do hereunder as
Escrow Agent or as attorney-in-fact for Purchaser while acting in good faith and
in the exercise of your own good judgment, and any act done or omitted by you
pursuant to the advice of your own attorneys shall be conclusive evidence of
such good faith.

         8. You are hereby expressly authorized to disregard any and all
warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law, and are hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case you obey or comply with any such order, judgment or decree of any
court, you shall not be liable to any of the parties hereto or to any other
person, firm or corporation by reason of such compliance, notwithstanding any
such order, judgment or decree being subsequently reversed, modified, annulled,
set aside, vacated or found to have been entered without jurisdiction.

         9. You shall not be liable in any respect on account of the identify,
authorities or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

         10. You shall not be liable for the outlawing of any rights under any
statute of limitations with respect to these Joint Escrow Instructions or any
documents deposited with you.

         11. Your responsibilities as Escrow Agent hereunder shall terminate if
you shall cease to be Counsel to the Corporation or if you shall resign by
written notice to each party. In the event of any such termination, the
Corporation shall appoint any officer or assistant officer of the Corporation as
successor Escrow Agent, and Purchaser hereby confirms the appointment of such
successor as his attorney-in-fact and agent to the full extent of your
appointment.

The issue of the Operating Licence for the creation and operation of a Health
Sector Database is subject to the provisions of Act No. 139/1998 on a Health

<PAGE>   3
    Further Conditions in the Operating Licence and Monitoring of Compliance

The Minister may attach further conditions to the Operating Licence beyond the
conditions established in Paragraph 1 of Article 5 of the Act. The Minister may
set the condition in the Operating Licence that individual work components in

shall be responsible for monitoring that conditions established in the Operating
Licence regarding individual work components are met as further provided in the
Operating Licence and in accordance with the division of tasks among the
Monitoring Committee and Data Protection Commission pursuant to Act No. 139/1998

Committee, the Data Protection Commission, the Interdisciplinary Ethics
Committee or the Licensee, establish new conditions in addition to the
conditions stipulated in the Operating Licence regarding the security of data in

                                   CHAPTER II

                              FINANCIAL SEGREGATION

The operation of the Health Sector Database shall be financially segregated from
other activities of the Licensee, cf. Paragraph 2 of Article 14 of the
Competition Act No. 8/1993. The operation of the Health Sector Database shall be
conducted within a separate operating unit or department, and keep separate
accounts. Accounting shall be conducted pursuant to the Act on Financial
Accounts. A separate Initial Balance Sheet shall be made. Assets regarded as
pertaining to the activities covered by the Operating Licence shall be appraised
at market value where possible, or at the replacement value following reasonable
depreciation. Liabilities of the activities covered by the Operating Licence
shall include only liabilities connected with such activities alone.

                                    Article 8

                 Pricing of Joint Use and Day-to-Day Management

All joint use of the operation subject to the Operating Licence and the

In the event that market price is not available, the value

                                    GOVT. REGULATION ON HEALTH SECTOR DATABASE 2
<PAGE>   4
shall be based on cost price plus a reasonable mark-up. Similarly, business
between the operation subject to the Operating Licence and other departments
shall be conducted on an arm's length basis.

When the utilisation of the Health Sector Database has begun, the party
responsible for the day-to-day administration of the operation subject to the
Operating Licence shall not be responsible for the administration of the
departments of the Licensee engaged in competitive activities.



                                   CHAPTER III

and such work shall be performed or managed by employees who are licensed
health-care professionals. The handling of health data by the Licensee shall
also be performed or managed by personnel who are licensed health-care
professionals. Those employees of health institutions and self-employed health
service workers who are directly employed in the transfer of health data to the
Health Sector Database shall not be involved in the Licensee's operation of the
Database. The Operating License shall be accompanied by a list of licensed
health-care professions at the time of issue of the Operating Licence.

                                   Article 10

specifications of the health authorities as current at any time.

                                   Article 11

                             Medical Records System

The Operating Licence shall establish general specifications for medical records
systems. The Licensee shall meet all conditions and requirements contained in
the specifications of the Operating Licence and also any later requirements and
conditions which the Minister may regard as necessary to achieve the objectives
of Act No. 139/1998.

                                   Article 12

                                Patients' Rights

A patient may at any time request that information concerning him is not
transferred to the Health Sector Database. A patient's request may involve all
information already available on the patient in medical records or which may be
recorded, or further specified information. Such a request from a patient shall
also be observed after his death.

In the event that a patient wishes to have information on him transferred to the
Health Sector Database, despite the fact that a health institution or
self-employed health service worker has not entered into an agreement on such
transfer of information, the patient shall submit a request to this effect to
the Directorate of Public Health. The Directorate of Public Health shall ensure
that such a request from a patient is carried out.

                                   Article 13

                      Access to the Health Sector Database

The Licensee may not grant direct access to the Health Sector Database.

Before processing is begun in the Database, the Licensee shall inform the
Monitoring Committee which parties in his employ work with the Database, its
operation and development of software and which parties in his employ have
access to the query layer. Furthermore, their roles and responsibilities shall
be defined, as well as their access authorisation. The Licensee shall notify the
Monitoring Committee of any intentions to confer responsibilities on new parties
pursuant to this provision and ensure that the Security Terms of the Data
Protection Commission are strictly observed.

                                   Article 14

                      Data from the Health Sector Database

                        Composition, Staff and Facilities

The Minister for Health and Social Security shall appoint a committee of three
members, the Monitoring Committee, for a term of four years to supervise the
creation and operation of the Health Sector Database. One member shall be a

The Committee shall be provided with staff and working facilities. The Committee
shall employ a Managing Director with a law degree. The Committee shall seek
expert advice as required.

                                   Article 16

                     Supervision of the Making of Agreements

The Monitoring Committee shall oversee the making of agreements between the
Licensee, on the one hand, and health institutions and self-employed health
service workers, on the other hand. The Committee shall protect the interests of
the public health authorities, health institutions, self-employed health service
workers and scientists in negotiating agreements. The negotiating parties shall
inform the Committee of the status of negotiations. Members of the Committee are
permitted to attend meetings of the negotiating parties at their discretion.

The Monitoring Committee shall, i.a., ensure co-ordination of the terms of the
Licensee's agreements with individual institutions to the extent possible, e.g.
as regards processing of health data, design of software, costs and payments.

                                    GOVT. REGULATION ON HEALTH SECTOR DATABASE 4
<PAGE>   6
The Monitoring Committee shall ensure that software for use in standardised
recording in health institutions and self-employed health service workers is
consistent with the specifications included in the Operating Licence and any
later specifications and requirements, cf. Articles 10 and 11 hereof. The
Committee shall ensure that the software enables data processing that will meet
the needs of individual health institutions and self-employed health service
workers for a co-ordinated information system, the needs of specialist fields
and the needs of public health authorities for access to statistical data from
the Database in accessible form so as to be useful in the preparation of health
reports, plans, policies and other projects of these parties. Measures shall
also be taken to ensure that the data can be used for scientific research.

Confirmation by the Monitoring Committee of an agreement between the Licensee
and individual health institutions or self-employed health service workers is a
prerequisite for the validity of the agreement. The parties shall be notified of
the Committee's conclusion within two weeks from the time that the agreement was
delivered to the Committee for confirmation.

                                   Article 17

                                  Surveillance

The Monitoring Committee shall monitor the day-to-day operation of the Database
and ensure that its creation and operation are consistent with the provisions of
law, regulations and the Operating Licence to the extent that such is not the
role of the Data Protection Commission under law.

                                   Article 18

                                 Access to Data

The Monitoring Committee may require from the Licensee and persons in the employ
of the Licensee any information necessary for the Committee to perform its tasks
pursuant to Act No. 139/1998, this Regulation and provisions of the Operating
Licence.

The Licensee shall ensure, e.g., that the Monitoring Committee always has access
to information on all research or queries or classes of queries submitted to the
Licensee for processing as well as to information on the research parties and
parties submitting queries in a form permitted by the Security Terms of the Data
Protection Commission.

The members of the Monitoring Committee and persons directly or indirectly in
its employ shall not divulge any confidential information that they acquire in
the course of their duty. The confidentiality obligation shall remain in force
even when employment ceases.

                                   Article 19

                              Advice on Use of Data

The Monitoring Committee shall advise the Ministry of Health and Social Security
and the Directorate of Public Health on utilisation of data in the Database.

                                   Article 20

                                  Backup Copies

             6. The operation of the database shall be financially separate from
the licensee's other business.

             7. The Ministry of Health and Social Security and the Director
General of Public Health shall at all times have access to statistical data from

processing for compiling health reports and planning, policy-making and other
projects of the parties specified.

<PAGE>   4
processed in a manner that fulfils the needs of the relevant institution or
self-employed health worker for a standardised information system, the needs of
medical specialist fields and the requirements of health authorities, cp. Clause
7, and so that it can be used in scientific research.

             9. The licence shall be temporary, and it shall not be granted for
more than 12 years at a time.

             10. The licensee shall hand over to the committee cp. art. 6 a copy

             11. The licensee shall ensure that after the expiry of the period
of the licence, the Minister of Health and Social Security, or the party
assigned by the Minister to operate the database, shall receive indefinite use
of all software and right required for the maintenance and operation of the

             The Minister may make the licence subject to further conditions
than those specified above.

             At the end of the period of the licence by the terms of the
licence, the Minister shall make a decision on the operation of the database,
after receiving the opinion of the committee cp. art. 6 and the Data Protection
Commission. The same applies if the licence is revoked or if the licence is
withdrawn from the licensee by the terms of this legislation.

             The licence and database under the terms of this legislation cannot
be transferred, nor can they be subjected to attachment for debt. Neither the
licence nor the database may be used as collateral for financial liabilities.

                                     Art. 6.
      Committee on the creation and operation of a health service database

             The Minister shall appoint a committee on the creation and
operation of a database under the terms of this legislation. The committee shall
comprise three people and three substitutes, appointed for four years at a time.
One shall be a health sector worker with a knowledge of epidemiology, another
shall have knowledge of information technology and/or computer science, and the
third shall be a lawyer, and shall chair the committee.

             Their substitutes shall fulfil the same conditions.

             The role of the committee is to ensure that the creation and
operation of the database are in keeping with the terms of this legislation,
regulations made on the basis of the legislation, and conditions laid down in
the operating licence, in so far as this does not fall within the ambit of the
Data Protection Commission. The committee shall supervise the negotiation of
contracts between the licensee on the one hand and health institutions and
self-employed health workers on the other. It shall protect the interests of
health authorities, health institutions, self-employed health workers and
scientists in the drawing up of agreements. The sum to be paid by the licensee
under the terms of para.3 art. 4. shall be negotiated by the committee, as shall
recompense in the form of access to data from the database for health
institutions, self-employed health workers and their staff for purposes of
scientific research.

             The committee shall advise the Ministry of Health and the Director
General of Public Health on the utilisation of data from the database. Should
the operating licence be revoked or the licence withdrawn from the licensee, the
database shall be
<PAGE>   5
operated by the committee until the Minister has reached a decision on its
long-term operation, cp. Para. 3, Art. 5.

             The committee shall be provided with staff and working facilities.
The committee shall seek specialist assistance as deemed necessary.

             The committee shall inform the Minister and the Data Protection
Commission without delay if it believes that there is some defect in the
operation of the database.

             The committee shall, no later than 1 March each year, submit a
report to the Minister on the operations of the past year


                                   SECTION III

                            Collection of information
                                     Art. 7
                       Access to data from health records

             With the consent of health institutions or self-employed health
workers, the licensee may be provided with data derived from medical records for
entry onto a health sector database. The health institutions shall confer with
the physicians' council and specialist management of the relevant institution
before contracts are concluded with the licensee.

             In the handling of records, other data and information, the
conditions deemed necessary by the Data Protection Commission at any time shall
be complied with.

             Personal identification shall be coded before entry on the
database, so that it is ensured that the licensee's staff work only with
non-personally identifiable data. The staff of the relevant health institution
or self-employed health workers shall prepare the data for entry on the
health-sector database. Health data shall be transferred in coded form in order
to ensure their security. Personal identification shall be coded one-way, i.e.
by coding that cannot be traced using a decoding key. The Data Protection
Commission shall carry out further coding of personal identification, using
those methods that the commission deems to ensure confidentiality best.

             With regard to access to data from medical records, this shall
otherwise be subject to the Acts on the rights of patients, on physicians, on
the health service and on the recording and handling of personal data.

                                     Art. 8
                               Rights of patients

             A patient may request at any time that information on him/her not
be entered onto the health-sector database. The patient's request may apply to
all existing information on him/her or that which may be recorded in the future,
or to some specific information.

             Such a request must be complied with. The patient shall inform the
Director General of Public Health of his/her wish. The Director General of
Public Health shall produce forms for giving such notice, and shall ensure that
these are available at health institutions and at the premises of self-employed
health workers. The Director General of Public Health shall ensure that a coded
register of the relevant patients is always accessible for those who carry out
the entry of data onto the health-sector database.
<PAGE>   6
             The Director General of Public Health shall ensure that information
on the health-sector database and on the rights of patients cp. para. 1 shall be
accessible to the public.

             Health institutions and self-employed health workers shall have
this information available to patients on their premises.

                                   SECTION IV
              Access to the database and utilisation of data, etc.
                                     Art. 9
       Access by health authorities to data on the health-sector database

             The Ministry of Health and Director General of Public Health shall
always be entitled to statistical data from the health sector database so that
it may be used in statistical processing for the making of health reports and
planning, policy-making and other projects of these bodies. This information to
the specified parties shall be provided free of charge.

                                    Art. 10.
                    Utilisation of the health sector database

             Data recorded or acquired by processing on the health-sector
database may be used to develop new or improved methods of achieving better
health, prediction, diagnosis and treatment of disease, to seek the most
economic ways of operating health services, and for making reports in the health
sector.

             The licensee shall be authorised to process data on the health
sector database from the health data recorded there, provided that data are
processed and connected in such a way that they cannot be linked to identifiable
individuals. The licensee shall develop methods and protocols that meet the
requirements of the Data Protection Commission in order to ensure
confidentiality in connecting data from the health-sector database, from a
database of genealogical data, and from a database of genetic data. With regard
to linking the data on the health-sector database with other databases than
those specified here, the Act on recording and handling of personal data shall
apply. It is not permissible to give information on individuals, and this shall
be ensured e.g. by limitation of access.

             The licensee may not grant direct access to data on the database.

             The licensee is authorised during the period of the licence to use
the data on the database for purposes of financial profit, under the conditions
laid down in this legislation and the licence.

             The health service database may not be transported out of Iceland,
and processing of it may only be carried out here in Iceland.

                                     Art. 11
                                 Confidentiality

             Employees of the licensee, including contractors, are bound by an
obligation of confidentiality on matters that they become aware of in their work
which should remain confidential, by law or by their nature. They shall sign an
oath of confidentiality before they begin work. The obligation of
confidentiality remains in force, even if employment ceases.

                                    SECTION V
                                   Monitoring
                                     Art. 12

             Monitoring of the creation and operation of a health-sector
database

             The Data Protection Commission shall monitor the creation and
operation of the health sector database with regard to recording and handling of
personal data and the security of data on the database, and is responsible for
monitoring compliance with conditions laid down by the commission.

             The committee on the operation of the database, cp. Art. 6, shall
be responsible for monitoring the compliance in every way of the activities of
the health sector database with the terms of this legislation, regulations
issued under the terms of this legislation, and the conditions of the licence.
The committee shall monitor all questions to and processing from the database.
It shall regularly send to the Science Ethics Committee a record of all
questions processed on the database, together with information on the enquirers.

             The minister shall issue regulations on an interdisciplinary ethics
committee which shall assess studies carried out within the licensee's company
and questions which are received. The committee's evaluation must reveal that
there is no scientific or ethical reason to prevent the study in question being
carried out, or the questions processed from the database.

                                   SECTION VI
                                    Penalties
                                     Art. 13
                              Revocation of licence

             The Minister may revoke the licence under the terms of this
legislation if the licensee or the licensee's employees violate the terms of
legislation, if the conditions of the licence are not fulfilled, or if the
licensee becomes unable to operate the database. Should the licensee violate the
terms of this legislation or not comply with the conditions of the licence, the
Minister shall give the licensee a written warning, allowing a reasonable period
of grace to rectify matters. Should the licensee not comply with such a warning,
the licence shall be revoked. In the case of deliberate violation or gross
negligence, the Minister may revoke the licence without notice and without
allowing time for rectification.

                                     Art. 14
                                    Penalties

             Violation of the terms of this legislation entails fines or
imprisonment for up to three years, unless a more severe penalty is prescribed
in other legislation.

             The same penalties apply to failure to comply with the conditions
for granting of an operating licence under the terms of this legislation, or
government regulations under the terms of the legislation, or failure to comply
with a command or prohibition under the terms of the legislation, or government
regulations under the terms of the legislation.

             A legal entity may be sentenced to pay fines due to violation of
this Act or regulations based on it. A legal entity may be fined regardless of
the guilt of its
<PAGE>   8
employees. The legal entity shall be responsible for payment of a fine imposed
upon an employee of the legal entity, provided that the offence is connected to
the employee's work for the legal entity.

                                     Art. 15
                           Withdrawal of licence etc.

             The licensee may, in addition to the penalties specified in Art.
14, be subject to revocation of the licence by legal verdict, in the case of
deliberate violation or gross negligence.

legislation may be confiscated, together with the profits of the violation, cp.
Art. 69 of the Penal Code no. 19/1940.

                                  Compensation

             Should the licensee, an employee of the licensee or a person
assigned to process data violate the provisions of this Act with regard to
confidentiality, regulations issued on the basis of them, or the conditions laid
down by the Data Protection Commission, the licensee shall compensate the person
to whom the data relate for financial loss which this has caused.

             The licensee, however, is not obliged to compensate for loss which
the licensee proves not to be attributable to a mistake or negligence on the
licensee's part, or that of an employee or processor.

                                   SECTION VII
                               Various provisions
                                     Art. 18

                                     DECODE

OUR COMPANY

     deCODE is a genomics and health informatics company which is developing
products and services for the healthcare industry. We develop and apply modern
informatics technology to discover new knowledge about health and disease
through data-mining. We believe that certain unique qualities of the Icelandic
population, together with our advanced bioinformatics and high throughput
genotyping facility, should place deCODE at a competitive advantage to perform
genetic and medical research to identify disease genes and drug and diagnostic
targets. As the international effort to sequence the human genome progresses, we
believe that the principal task will be to transform raw genomic data into
knowledge about human health and disease and then into tangible products and
services. We believe that deCODE is well-positioned to place the human genome
sequence in a meaningful context through which we and our partners can generate
value.

     deCODE was founded in 1996 and its operations, as well as its approximately
300 employees, are based in Iceland. In 1998, we entered into a significant
research collaboration and cross-license agreement with F.Hoffmann-La Roche, or
Roche, under which we may receive a total of more than $200 million in research
funding and milestone payments. To date our accomplishments include:

     -  the identification of eight locations for disease-causing genes;

     -  the identification of twelve specific candidate disease genes;

     -  the achievement of four milestones in our research collaboration
        agreement with Roche;

     -  the completion of a high-throughput genotyping facility;

     -  the development of automated software algorithms for data capture,
        analysis and interpretation; and

     -  near completion of a computerized genealogy database covering the
        Icelandic population.

     We believe that discovery of health care knowledge requires bringing
together three key types of data: information from the healthcare system,
information about relationships among individuals covered by this system and
associated molecular genetics data. We believe that operating in Iceland
accomplishes this by allowing us to benefit from the following four important
characteristics of the Icelandic nation in our medical and genetic research:

     -  extensive genealogical records dating back to the settlement of the
        country in the ninth century;

     -  relative genetic homogeneity with a population descended from a small
        number of settlers;

     -  a centralized healthcare system since 1915; and

     -  a well-educated population.

     We believe that bringing these four factors together greatly enhances our
research and development efforts in generating future products and services for
the healthcare industry.

     deCODE is pursuing its access to public and proprietary data through three
avenues of commercialization:

     -  discovery services, with a focus on gene and drug target discovery;

     -  database services, with a focus on the construction and
        commercialization of the Icelandic Health Sector Database, or the IHD,
        containing non-personally identifiable data from Icelandic healthcare
        records, and the deCODE Combined Data Processing capability, or the
        DCDP, to cross-reference data from the IHD with genealogical and
        genotypic data; and

     -  healthcare informatics, with a focus on bioinformatics, decision-support
        tools and privacy products.

                                        4
<PAGE>   6

     We believe that the DCDP will permit users to build more complete models of
the interplay of genes, the environment and disease than are currently
available.

OUR STRATEGY

     Our strategy is to use our population-based genomics approach to transform
genomic data and healthcare data into products and services. The key elements of
our strategy are as follows:

     -  Gene and Drug Target Discovery.  deCODE plans to pursue gene and drug
        target discovery and the characterization of genes that contribute to
        the causes of common diseases. In addition, we will use studies of gene
        expression and protein-protein interaction systems to define molecular
        pathways, which may contain drug targets.

     -  Database Subscription and Consulting Services.  deCODE expects to
        develop and operate the DCDP, which is intended to cross-reference
        non-personally identifiable healthcare information on the Icelandic
        population in the IHD with genealogy data and genetic data obtained
        through consent. In addition, we are developing new mathematical
        algorithms to extract further knowledge from the DCDP. Services we plan
        to offer to future subscribers of the DCDP will include gene discovery
        and drug target validation, pharmacogenomics, disease management and
        health management.

     -  Pharmacogenomics Partnerships.  In collaboration with pharmaceutical
        companies, we intend to apply pharmacogenomics to understand differences
        in drug response among individuals. We believe that genomics will permit
        the identification of the genetic differences that cause different
        people to respond differently to the same drugs and that, as a result,
        it will be possible to individualize the selection of drugs for
        patients.

     -  Sale and Marketing of Healthcare Informatics Products.  We plan to
        exploit market opportunities for software tools that we develop during
        the design and construction of the IHD and DCDP and in our disease gene
        discovery efforts. The software tools that we have already developed
        include GeneMiner, DecodeGT, an encryption system, and a comprehensive
        sample database. We expect to offer healthcare informatics services,
        such as decision-support software and privacy solutions.

     -  Formation of Collaborations.  We intend to seek corporate collaborations
        or joint ventures with pharmaceutical and biotechnology companies to
        provide research alliances, product development and commercialization
        for our gene and drug target discovery programs.

     deCODE was incorporated in Delaware in 1996. Our principal office is
located at Lynghals 1, Reykjavik, Iceland, our telephone number is +354-570-1900
and our address on the world wide web is www.decode.com.

                                  RISK FACTORS

     The shares of common stock offered by this prospectus involve a substantial
risk of loss. Before making an investment in the common stock, you should
carefully read this entire prospectus and should give particular attention to
the following risk factors. You should recognize that other significant risks
may arise in the future, which we cannot foresee at this time. Also, the risks
that we now foresee might affect us to a greater or different degree than
expected. There are a number of important factors that could cause our actual
results to differ materially from those indicated by the forward-looking
statements contained in this prospectus. These factors include, without
limitation, the risk factors listed below and other factors presented throughout
this prospectus.

WE MAY NOT SUCCESSFULLY DEVELOP OR DERIVE REVENUES FROM ANY PRODUCTS OR SERVICES

     DISCOVERY SERVICES

     Our gene discovery programs are still in the early stages of development
and may not result in marketable products. Our technology and development focus
is primarily directed toward identifying genes or gene fragments which are
responsible for, or indicate the presence of, certain diseases. We have only
identified twelve specific candidate genes under our research programs and have
not yet validated any disease genes. Our technologies and approach to gene
discovery may not enable us to identify successfully the specific genes that
cause or predispose individuals to the complex diseases that are the targets of
our gene discovery program, even where we have identified candidate genes. In
addition, the diseases we are targeting are generally believed to be caused by a
number of genetic and environmental factors. It may not be possible to address
such diseases through gene-based therapeutic or diagnostic products.
Accordingly, even if we are successful in identifying specific genes, our
discoveries may not lead to the development of commercial products.

     Even if we, or our collaborators, are able to develop pharmaceutical
products, those products will fail to produce revenues unless they:

     -  are safe and effective;

     -  meet regulatory standards in a timely manner;

     -  successfully compete with other technologies and products;

     -  avoid infringing on the proprietary rights of others;

     -  can be manufactured in sufficient quantities at reasonable costs; and

     -  can be marketed successfully.

     We are not certain that we will be able to achieve these conditions for
product revenues. We expect that it will be a number of years, if ever, before
we will recognize revenue from therapeutic or diagnostic product sales or
royalties on such sales.

     Our initiatives in pharmacogenomics and functional genomics are not certain
to provide any revenues. There may be no market for these services because of
competition, lack of market acceptance or our inability to develop these
services successfully. We may not be able to develop our functional genomics
capabilities to a state that is adequate for realizing revenues.

     DATABASE SERVICES

     We, through our wholly-owned subsidiary Islensk erfethagreining ehf.,
received a license permitting us to develop and operate the IHD in January 2000,
and accordingly, are at the very early stages of its development. The collection
of genotypic data, that is another integral part of the DCDP, is also in the
early stages of development. We expect that it will take several years before
the DCDP is fully developed. We are presently devoting substantial resources to
the development of the DCDP and its components. We plan to continue to devote
substantial resources to this development for the foreseeable future. We cannot
be sure that the DCDP will result in marketable products or services. Our
intended method for cross-referencing genealogical, genotypic and

                                        8
<PAGE>   10

healthcare data is central to the development of the DCDP and is unproven. The
success of our database services is contingent upon:

     -  the development of the IHD and collection of genotypic data;

     -  the creation of database and cross-reference software that is free from
        design defects or errors;

     -  compliance with governmental requirements regarding the IHD;

     -  the security and reliability of encryption technology;

     -  the cooperation of the Icelandic healthcare system;

     -  the ability to obtain blood samples from consenting Icelanders and
        consents to the use of their genotypic data by cross-referencing through
        the DCDP;

     -  the usefulness of information derived through the DCDP in disease
        management, analysis of drug response, gene discovery and drug target
        validation; and

     -  the development of marketing and pricing methods that are accepted by
        the intended users of the DCDP.

     The failure to successfully commercialize our database services will have a
material adverse effect on our business operations.

     HEALTHCARE INFORMATICS

     Our bioinformatics, decision-support and privacy protection products have,
to date, been tested only in connection with our own use of them and they may
not meet the needs of potential customers. We are at an early stage of
development of our medical decision-support systems, or MDSS, for healthcare
providers, and we have generated no revenues from sales or licenses of
bioinformatics, decision-support, or privacy protection products. To date we
have not produced any decision-support tools and there can be no assurance that
we can successfully develop or commercialize MDSS or that there will be a market
for our bioinformatics, decision-support or privacy protection products for
healthcare delivery.

OUR BUSINESS MODEL IS BASED ON UNPROVEN APPROACHES

     The products we hope to develop involve new and unproven approaches. They
are based on the assumption that information about genes may help scientists
better understand complex disease processes. Scientists generally have a limited
understanding of the role of genes in diseases, and few products based on gene
discoveries have been developed. Of the products that exist, all are diagnostic
products. To date, we know of no therapeutic products based on disease gene
discoveries. If our assumption about the role of genes in the disease process is
wrong, our gene discovery programs may not result in products, the genetic data
included in our database and informatics products may not be useful to our
customers and those products may lose any competitive advantage.

IF WE CONTINUE TO INCUR OPERATING LOSSES FOR A PERIOD LONGER THAN ANTICIPATED,
OR IN AN AMOUNT GREATER THAN ANTICIPATED, WE MAY BE UNABLE TO CONTINUE OUR
OPERATIONS

     We incurred net losses available to common stockholders of $61,607,605 for
the year ended December 31, 1999, $13,479,753 for the year ended December 31,
1998, and $8,676,626 for the year ended December 31, 1997. As of December 31,
1999 we had an accumulated deficit of $76,713,517. To date, we have never
generated a profit and we have not generated any significant revenues except for
payments received in connection with our research collaboration with Roche and
interest revenues. The development of our technologies will require substantial
increases in expenditures over the next several years. In addition, we expect to
spend more in connection with our internal research programs and the preparation
of the IHD, the DCDP and informatics. As a result, we expect to incur operating
losses for several years. If the time required to generate product revenues and
achieve profitability is longer than anticipated or the level of operating
losses is greater than anticipated, we may not be able to continue our
operations.

                                        9
<PAGE>   11

WE MAY NOT BE ABLE TO OBTAIN SUFFICIENT ADDITIONAL FUNDING TO MEET OUR EXPANDING
CAPITAL REQUIREMENTS

     We have used substantial amounts of cash to fund our research and
development activities. We expect our capital and operating expenditures to
increase over the next several years as we expand our research and development
activities, construct the IHD and the DCDP, collect the genotype data and
develop healthcare informatics products. Many factors will influence our future
capital needs, including:

     -  the progress of our discovery and research programs;

     -  the number and breadth of these programs;

     -  our ability to attract collaborators for, subscribers to or customers
        for our products and services;

     -  our achievement of milestones under our research collaboration agreement
        with Roche;

     -  our ability to establish and maintain additional collaborations;

     -  our collaborators' progress in commercializing our gene discoveries;

     -  the level of our activities relating to commercialization rights we
        retain in our collaborations;

     -  competing technological and market developments;

     -  the costs involved in enforcing patent claims and other intellectual
        property rights; and

     -  the costs and timing of regulatory approvals.

     We intend to rely on Roche and future collaborators for significant funding
in support of our research efforts. In addition, we may seek additional funding
through public or private equity offerings and debt financings. Additional
financing may not be available when needed. If available, such financing may not
be on terms favorable to us or our stockholders. Stockholders' ownership will be
diluted if we raise additional capital by issuing equity securities. If we raise
additional funds through collaborations and licensing arrangements, we may have
to relinquish rights to certain of our technologies or product candidates, or
grant licenses on unfavorable terms. These situations could have a material
adverse effect on us. If adequate funds are not available, we would have to
scale back or terminate our discovery and research programs and product
development, and our business, financial condition and results of operations
would be materially adversely affected. We believe that the net proceeds from
this offering, existing cash and investment securities and anticipated cash flow
from Roche will be sufficient to support our current operating plan at least
through 2001. We have based this belief on assumptions that may prove wrong.

IF WE DO NOT MAINTAIN THE GOODWILL AND RECEIVE THE COOPERATION OF THE ICELANDIC
POPULATION, WE MAY BE UNABLE TO PURSUE OUR GENE IDENTIFICATION PROGRAMS,
PHARMACOGENOMICS OR FUNCTIONAL GENOMICS EFFORTS, COLLECT GENOTYPE DATA OR
DEVELOP THE IHD AND THE DCDP

     Our approach to gene identification and the development and maintenance of
genotype data, the IHD and the DCDP depend on the goodwill and cooperation of
the Icelandic population, including the Icelandic government and the healthcare
system. Our development of the IHD will be impaired if individual Icelanders
refuse to allow information from their medical records to be included in the IHD
or healthcare providers attempt to prevent us from having access to medical
records of their patients. Our development of genotype data and our cross-
referencing through the DCDP of that data with information about the
manifestations of disease, or phenotypes, in the IHD require that a substantial
portion of the Icelandic population provide us with blood samples for genotyping
and consent to the use of their DNA to cross-reference molecular genetics data
with the IHD. Because certain mutations may be carried only by a small portion
of the Icelandic population, the unwillingness of even a small portion of the
population to participate in our programs could diminish our ability to develop
and market information based on the use of genotypic data. Accordingly, if we do
not maintain the goodwill of the Icelandic people and receive the cooperation of
individual Icelanders and the medical profession, our business and financial
condition will be materially adversely affected.

                                       10

OUR RELIANCE ON THE ICELANDIC POPULATION IN OUR GENE DISCOVERY PROGRAMS AND
DATABASE SERVICES MAY LIMIT THE APPLICABILITY OF OUR DISCOVERIES TO CERTAIN
POPULATIONS

     In general, the genetic make-up and prevalence of disease vary across
populations around the world. Common complex diseases generally occur with a
similar frequency in Iceland as in other western countries. We are already
studying some of these diseases in our gene discovery programs. However, the
populations of other western nations may be genetically predisposed to certain
diseases because of mutations not present in the Icelandic population. As a
result, we and our partners may take more time or may be unable to develop
diagnostic products that are effective on all, or a portion, of those people
with such diseases. Similarly, any difference between the Icelandic population
and the populations of other countries may have an effect on the usefulness of
the IHD and DCDP in studying disease in populations of countries other than
Iceland.

OUR CREATION AND OPERATION OF THE IHD IS BASED UPON A LICENSE FROM THE ICELANDIC
MINISTRY OF HEALTH AND SOCIAL SECURITY AND IS SUBJECT TO GOVERNMENT SUPERVISION
AND REGULATION

     We are only permitted to construct the IHD and cross-reference it with our
genealogical and genetic data, through the DCDP, in accordance with the
stipulations of the license, or the IHD license, granted by the Ministry of
Health and Social Security, or the Ministry, pursuant to the Act on a Health
Sector Database no. 139/1998, or the Act. The license permits the processing of
healthcare data from healthcare records and other relevant data into the IHD.
Our construction and operation of the IHD will be subject to the supervision of
the IHD Monitoring Committee, the Data Protection Commission of Iceland and an
Interdisciplinary Ethics Committee. These committees report to the Ministry. In
addition, the operation of the IHD is subject to the review of the Icelandic
Bioethics Committee. The Ministry may withdraw our license in the event that we
violate the terms and conditions of the IHD license, the Act or the rules
promulgated pursuant to the Act. In addition, the Act could be amended in ways
which would adversely affect our ability to develop or market the IHD and,
consequently, the DCDP. Because the Act and the rules were recently adopted by
the Icelandic parliament and government, there is no precedent interpreting the
Act or the rules.

     Our preparation of the IHD is subject to technical requirements imposed by
the Data Protection Commission in areas such as data encryption and privacy
protection. These requirements are subject to change from time to time and may
require greater technical capabilities than we currently have. Compliance with
these requirements can be expensive and time-consuming and may delay the
development of the IHD and the DCDP or make such development more expensive than
anticipated. In addition, our compliance is subject to evaluation by the
agencies imposing these requirements. We cannot control the time required for
this evaluation, and accordingly, the evaluation process may lead to delay in
the development of the IHD and the DCDP.

     The Interdisciplinary Ethics Committee has the power to withdraw permission
for any types of research programs in the IHD not conducted in accordance with
international rules of bioethics.

     At the expiration of the IHD license, we are required to ensure that the
Ministry or a party entrusted by the Ministry will receive, without payment of
consideration, intellectual property rights necessary for the creation and
operation of the database for public health purposes and for scientific
research.

     We are subject to a very extensive indemnity clause in our agreement with
the Ministry, pursuant to which:

     -  we have agreed not to make any claim against the government if the Act
        or the license are amended as a result of the Act or rules relating to
        the IHD being found to be inconsistent with the rules of the European
        Economic Area, or EEA, or other international rules and agreements to
        which Iceland is or becomes a party;

     -  we have agreed that if the Icelandic State, by a final judgment, is
        found to be liable or subject to payment to any third party as a result
        of the passage of legislation on the IHD and/or issuance of the IHD
        license, we will indemnify it against all damages and costs in
        connection with the litigation; and

     -  we have agreed to compensate any third parties with whom the Icelandic
        government negotiates a settlement of liability claims arising from the
        legislation on the IHD and/or the issuance of the IHD

                                       11
<PAGE>   13

       license, provided that the Icelandic government demonstrates that it was
       justified in agreeing to make payments pursuant to the settlement.

WE MAY NOT BE ABLE TO ENTER INTO AGREEMENTS WITH ICELANDIC HEALTH INSTITUTIONS
AS REQUIRED BY THE IHD LICENSE IN ORDER TO COLLECT DATA FROM THE INSTITUTIONS

     The IHD license requires us to enter into agreements with Icelandic health
institutions and self-employed health service workers regarding access to and
the processing of information from medical records. We cannot be certain that we
will be able to enter into such agreements or that such agreements will be on
terms favorable to us. We cannot be certain that individuals within health
institutions will adhere to the requirements of such agreements. Our inability
to enter into such agreements on favorable terms or in a timely manner, or to
obtain others' compliance with the terms of such agreements, could have a
material adverse effect on us.

THE IHD LICENSE WILL EXPIRE IN JANUARY 2012

     Even if we are successful in creating and marketing the IHD and the DCDP,
the IHD license will expire in January 2012 unless we are able to obtain an
extension. There is no assurance that we will obtain further access rights on
favorable terms, if at all. Our negotiations with healthcare institutions, the
process of genotyping and the development of database infrastructure, among
other factors, will determine when we can begin marketing the DCDP. We expect
that the IHD and the DCDP will not be fully operational for up to five years.
The IHD license will be subject to a review in 2008, and at that time, in
accordance with an agreement we entered into with the Ministry simultaneously
with the granting of the IHD license, we and the Ministry will enter into
discussions on renewal of the license at the end of the term. The Ministry is
not obligated to renew the IHD license and there can be no guarantee that it
will do so. Failure to maintain the IHD license or to complete the IHD or the
DCDP in a timely fashion will materially adversely affect our business and
financial condition.

WE MAY NOT BE ABLE TO FORM AND MAINTAIN THE COLLABORATIVE RELATIONSHIPS THAT OUR
BUSINESS STRATEGY REQUIRES

     Our strategy for deriving revenues from the discovery of genes and the
development of products based upon our discoveries depends upon the formation of
research collaborations and licensing arrangements with several partners at the
same time. We currently have a research collaboration only with Roche. To
succeed, we will have to maintain this relationship and establish additional
collaborations. We cannot be sure that we will be able to establish additional
research collaborations or licensing arrangements necessary to develop and
commercialize products using our technology, that any future collaborations or
licensing arrangements will be on terms favorable to us, or that current or
future collaborations or licensing arrangements ultimately will be successful.
If we are not able to manage multiple programs successfully, our programs will
suffer.

     We also expect to rely on collaborations in other parts of our business
such as the construction of the DCDP. During the development of the DCDP, we
intend to pursue collaborations to assist us in the development of certain of
its components. Such collaborations may involve the use of particular
technologies or collaborative development and marketing activities. If we are
unable to enter into such collaborations on favorable terms, our ability to
commercialize the DCDP will be adversely affected.

     To develop our healthcare informatics products, we also plan to rely on
collaborative relationships. To date we have not established any such
collaborative relationships. If we are unable to form or maintain such
collaborative arrangements, our healthcare informatics operations will be
adversely affected.

OUR DEPENDENCE ON COLLABORATIVE RELATIONSHIPS MAY LEAD TO DELAYS IN PRODUCT
DEVELOPMENT AND DISPUTES OVER RIGHTS TO TECHNOLOGY

     Under our current strategy, and for the foreseeable future, we do not
expect to develop or market pharmaceutical products on our own. As a result, we
will be dependent on collaborators for the pre-clinical study and clinical
development of therapeutic and diagnostic products and for regulatory approval,
manufacturing and marketing of any products that result from our technology. Our
agreements with pharmaceutical collaborators or collaborators for gene research
projects will typically allow them significant discretion in electing whether to
                                       12
<PAGE>   14

pursue such activities. We cannot control the amount and timing of resources
collaborators will devote to our programs or potential products. Our
collaborations may have the effect of limiting the areas of research that we may
pursue either alone or with others.

     In addition, we expect to develop our database products, in part, with
various collaborators, and we may develop healthcare informatics tools which are
designed to work in conjunction with or to enhance the healthcare informatics
tools of other developers. These arrangements may place responsibility for key
aspects of product development and marketing on our collaborative partners.
Accordingly, the performance of these key aspects is uncertain and beyond our
direct control. The failure of our collaborators to perform their obligations
could result in our database products containing erroneous data, design defects,
viruses or software defects that are difficult to detect and correct and may
adversely affect our revenues and the market acceptance of our products.

     If any pharmaceutical, healthcare informatics or database collaborator were
to breach or terminate its agreement with us, or otherwise fail to conduct
collaborative activities successfully and in a timely manner, the development or
commercialization of products, services, technologies or research programs may
be delayed or terminated.

     Competing products, developed by our collaborators or to which our
collaborators have rights, may result in their withdrawal of support for our
products and services.

     Disputes may arise in the future over the ownership of rights to any
technology developed with collaborators. These and other possible disagreements
between us and our collaborators could lead to delays in the collaborative
research, development or commercialization of products. Such disagreements could
also result in litigation or require arbitration to resolve. Any such event
could have a material adverse effect on our business.

ETHICAL AND PRIVACY CONCERNS MAY LIMIT OUR ABILITY TO DEVELOP AND USE THE IHD
AND DCDP AND MAY LEAD TO LITIGATION AGAINST US OR THE ICELANDIC GOVERNMENT

     The passage of the Act and the granting by the Ministry of the IHD license
have raised ethics and privacy concerns in Iceland and internationally, among
healthcare professionals and others. Ethical and privacy concerns about the
development and use of the IHD and DCDP may lead to litigation in U.S.,
Icelandic or other national courts, or in international courts such as the
European Court of Human Rights in Strasbourg, e.g., on the basis of an alleged
breach of the patient-doctor confidential relationship, constitutional privacy
issues, international conventions dealing with protection of privacy issues or
human rights conventions. The results of such litigation could materially
adversely affect our results of operations.

CERTAIN PARTIES HAVE ANNOUNCED AN INTENTION TO INSTITUTE LITIGATION TESTING THE
CONSTITUTIONALITY OF THE ACT

     In February 2000, an organization known as The Association of Icelanders
for Ethics in Science and Medicine, or Mannvernd, and a group of physicians and
other citizens issued a press release announcing their intention to file
lawsuits against the State of Iceland and any other relevant parties, including
deCODE, to test the constitutionality of the Act. According to the press
release, the intended lawsuit will allege that the Act and the IHD license
involve human rights violations and will challenge the validity of provisions of
the Act which allow the use of presumed consent for the processing of health
data into the IHD and the grant of a license to operate a single database.
deCODE believes that any such litigation would be without merit and intends to
defend vigorously any such action in which we become a party. However, in the
event that the Icelandic State by a final judgment is found to be liable or
subject to payment to any third party as a result of the passage of legislation
on the IHD and/or the issuance of the IHD license, our agreement with the
Ministry requires us to indemnify the Icelandic State against all damages and
costs incurred in connection with such litigation. In addition, the pendency of
such litigation could lead to delay in the development of the IHD and the DCDP,
and an unfavorable outcome would prevent us from developing and operating the
IHD and the DCDP. This would have a material adverse effect on our business and
financial condition.

                                       13
<PAGE>   15

ANY FAILURE TO PROTECT CONFIDENTIAL DATA ADEQUATELY COULD CAUSE US TO INCUR
LIABILITY OR COULD RESULT IN LOSS OF OUR LICENSE

     The Act and our license require us to encrypt all patient data and to take
other actions to ensure confidentiality of data included in the IHD and restrict
access to it. We are developing the IHD in accordance with the technology,
security and organizational terms established by the Data Protection Commission.
Such terms may be periodically reviewed and amended by the Data Protection
Commission in light of new technology or change of circumstances. We will be
required to comply with the revised data protection terms within an established
deadline. Although the security terms established by the Data Protection
Commission have, to date, received some criticism by one expert in this field,
we believe that they are, and will continue to be, in line with international
best industry-practice standards. In addition, the customers for other products
we may develop may impose confidentiality requirements. Accidental disclosures
of confidential data may result from technical failures in encryption technology
or from human error by our employees or those of our customers or collaborators.
Any failure to comply fully with all confidentiality requirements could lead to
liability for damages incurred by individuals whose privacy is violated, the
loss of the IHD license, the loss of our customers and reputation and the loss
of the goodwill and cooperation of the Icelandic population including healthcare
professionals. Any of these events would have a material adverse effect on our
business and financial condition.

ETHICAL AND PRIVACY CONCERNS MAY LIMIT THE USE OF GENETIC TESTING

     Existing genetic predisposition tests developed by other companies have
raised ethical concerns. It is possible that employers or others could
discriminate against people who have a genetic predisposition to certain
diseases. Concern regarding possible discrimination may result in governmental
authorities enacting restrictions or bans on the use of all, or certain types
of, genetic testing. Similarly, such concerns may lead individuals to refuse to
use genetics tests even if permissible. These factors may limit the market for,
and therefore the commercial viability of, products developed by us and our
collaborators.

THERE IS INTENSE COMPETITION FOR THE DEVELOPMENT AND MARKETING OF PRODUCTS BASED
UPON THE IDENTIFICATION OF DISEASE-CAUSING GENES

     A number of companies are attempting to rapidly identify and patent genes
that cause diseases or an increased susceptibility to diseases. Competition in
this field is intense and is expected to increase. We have numerous competitors,
including major pharmaceutical and diagnostic companies, specialized
biotechnology firms, universities and other research institutions, the United
States-funded Human Genome Project and other government-sponsored entities. Many
of our competitors have considerably greater capital resources, research and
development staffs and facilities, and technical and other resources than we do,
which may allow them to discover important genes before we do. We believe that a
number of our competitors are developing competing products and services that
may be commercially successful and that are further advanced in development than
our potential products and services. To succeed, we, together with our
collaborators, must discover disease-predisposing genes, characterize their
functions, develop genetic tests or therapeutic products and related information
services based on such discoveries, obtain regulatory and other approvals, and
launch such services or products before competitors. Even if our collaborators
or we are successful in developing effective products or services, our products
and services may not successfully compete with those of our competitors. Our
competitors may succeed in developing and marketing products and services that
are more effective than ours or that are marketed before ours.

     Our collaboration with Roche does not prevent it from initiating its own
gene research or developing products based upon its, or any other party's, gene
research. Such products may compete with any products developed as a result of
our gene discovery programs. We expect that future collaborations may allow our
future partners to undertake research and develop products on their own or with
third parties.

     Competitors have established, and in the future may establish, patent
positions with respect to gene sequences related to our research projects. Such
patent positions or the public availability of gene sequences comprising
substantial portions of the human genome could decrease the potential value of
our research projects

                                       14
<PAGE>   16

and make it more difficult for us to compete. We may also face competition from
other entities in gaining access to DNA samples used for research and
development purposes.

     We expect competition to intensify as technical advances are made and
become more widely known. Our future success will depend in large part on
maintaining a competitive position in the genomics field. Rapid technological
development by us or others may result in products or technologies becoming
obsolete before we recover the expenses we incur in developing them. Less
expensive or more effective technologies could make future products obsolete. We
cannot be certain that we will be able to make the necessary enhancements to any
products we develop to compete successfully with newly emerging technologies.

THERE IS INTENSE COMPETITION IN THE FIELD OF DATABASE SERVICES

     A number of databases are being marketed or are under development by
companies or governments to assist participants in the healthcare industry and
academic researchers in the management and analysis of their own genomic data
and data available in the public domain. Although we believe that our existing
genealogy database and our license to construct and operate the IHD provide us
with a unique opportunity to cross-reference databases that include genetic
makeup, genealogy, medical history, disease symptoms, resource use and treatment
outcomes, we cannot be sure that any databases created by us will achieve
greater market acceptance than those of our competitors.

THERE IS INTENSE COMPETITION IN THE FIELD OF HEALTHCARE INFORMATICS

     The healthcare informatics field is highly competitive. Many companies
compete with us to develop healthcare informatics similar to our expected
products, including products relating to medical record maintenance, MDSS and
systems design. We expect that competition will continue to intensify. Many of
our competitors have significantly greater financial resources and market
presence than we have. We cannot be sure that any products that we develop in
the field of healthcare informatics, including MDSS, will compete effectively
with those of our competitors.

REGULATORY AUTHORITIES MAY DETERMINE THAT OUR LICENSE TO DEVELOP THE IHD
INFRINGES UPON COMPETITION RULES IN THE EUROPEAN ECONOMIC AREA

     Iceland is a member of the European Free Trade Association, or EFTA,
together with Norway, Switzerland and Liechtenstein. Through this membership,
Iceland has become a part of the EEA which was created by the EEA agreement
between EFTA and the European Union, or EU. The EEA agreement extends the EU
internal market and its regulations to EFTA countries that adopt certain EU
legislation. Accordingly, Iceland is subject to both EFTA and EU competition and
public procurement rules. In April 1999, Mannvernd, announced that it had filed
a complaint with the EFTA Surveillance Authority alleging that the passage of
the Act constitutes a violation by the Government of Iceland of its obligations
under the EEA agreement. A determination that the Act or our IHD license is in
breach of such rules could result in a revocation or dilution of the license and
could have a negative impact on the profitability and marketing potential of the
DCDP.

OTHERS MAY CLAIM INTELLECTUAL PROPERTY RIGHTS TO OUR GENEALOGY DATABASE

     We are aware that there are other firms and individuals who have prepared,
or are currently preparing, genealogy databases similar to the one we have
developed. If any parties should successfully claim that the creation or use of
any of our databases infringes upon their intellectual property rights, it could
have a material adverse effect on our business. Recently, two holders of
copyrights in approximately 100 Icelandic genealogy books have filed a copyright
infringement suit against us in Iceland claiming that we have used data from
these books in the creation of our genealogy database, in violation of their
rights. The claimants seek a declaratory judgment to prevent our use of the
database and monetary damages in the amount of approximately $9,000,000. We
believe that this suit is without merit and intend to defend it vigorously, but
if it were successful it could have a material adverse effect on our database
and gene discovery services.

                                       15

WE MAY NOT BE ABLE TO PROTECT THE PROPRIETARY RIGHTS THAT ARE CRITICAL TO OUR
SUCCESS

     Our success will depend on our ability to protect our genealogy database
and genotypic data and any other proprietary databases that we develop,
proprietary software and other proprietary methods and technologies. Despite our
efforts to protect our proprietary rights, unauthorized parties may be able to
obtain and use information that we regard as proprietary.

     Our commercial success will depend in part on obtaining patent protection.
The patent positions of pharmaceutical, biopharmaceutical and biotechnology
companies, including ours, are generally uncertain and involve complex legal and
factual considerations. We cannot be sure that any of our pending patent
applications will result in issued patents, that we will develop additional
proprietary technologies that are patentable, that any patents issued to us or
our partners will provide a basis for commercially viable products, will provide
us with any competitive advantages or will not be challenged by third parties,
or that the patents of others will not have an adverse effect on our ability to
do business.

     In addition, patent law relating to the scope of claims in the area of
genetics and gene discovery is still evolving. There is substantial uncertainty
regarding the patentability of genes or gene fragments without known functions.
The laws of some European countries provide that genes and gene fragments may
not be patented. The Commission of the EU has passed a directive which prevents
the patenting of genes in their natural state. The U.S. Patent and Trademark
Office initially rejected a patent application by the National Institutes of
Health on partial genes. Accordingly, the degree of future protection for our
proprietary rights is uncertain and, we cannot predict the breadth of claims
allowed in any patents issued to us or to others. We could also incur
substantial costs in litigation if we are required to defend ourselves in patent
suits brought by third parties or if we initiate such suits.

     Others may have filed and in the future are likely to file patent
applications covering genes or gene products that are similar or identical to
our products. We cannot be certain that our patent applications will have
priority over any patent applications of others. The mere issuance of a patent
does not guarantee that it is valid or enforceable; thus even if we are granted
patents we cannot be sure that they would be valid and enforceable against third
parties. Further, a patent does not provide the patent holder with freedom to
operate in a way that infringes the patent rights of others. Any legal action
against us or our partners claiming damages and seeking to enjoin commercial
activities relating to the affected products and processes could, in addition to
subjecting us to potential liability for damages, require us or our partners to
obtain a license in order to continue to manufacture or market the affected
products and processes. There can be no assurance that we or our partners would
prevail in any action or that any license required under any patent would be
made available on commercially acceptable terms, if at all. If licenses are not
available, we or our partners may be required to cease marketing our products or
practicing our methods.

     If expressed sequence tags, single nucleotide polymorphisms, or SNPs, or
other sequence information become publicly available before we apply for patent
protection on a corresponding full-length or partial gene, our ability to obtain
patent protection for those genes or gene sequences could be adversely affected.
In addition, other parties are attempting to rapidly identify and characterize
genes through the use of gene expression analysis and other technologies. If any
patents are issued to other parties on these partial or full-length genes or
uses for such genes, the risk increases that the sale of our or our
collaborators' potential products or processes may give rise to claims of patent
infringement. The amount of supportive data required for issuance of patents for
human therapeutics is highly uncertain. If more data than we have available is
required, our ability to obtain patent protection could be delayed or otherwise
adversely affected. Even with supportive data, the ability to obtain patents is
uncertain in view of evolving examination guidelines, such as the utility and
written description guidelines proposed by the U.S. Patent and Trademark Office.

     While we require employees, academic collaborators and consultants to enter
into confidentiality agreements, there can be no assurance that proprietary
information will not be disclosed, that others will not independently develop
substantially equivalent proprietary information and techniques, otherwise gain
access to our trade secrets or disclose such technology, or that we can
meaningfully protect our trade secrets.

                                       16
<PAGE>   18

     If the information processed by the DCDP is disclosed without our
authorization, demand for our products and services may be adversely affected.

WE CANNOT BE CERTAIN THAT REGULATORY APPROVALS WILL BE OBTAINED FOR PRODUCTS
RESULTING FROM OUR GENE DISCOVERY PROGRAMS

     New drugs and diagnostic products must be approved by government agencies
in the countries in which they are to be marketed. We cannot be certain that
regulatory approval for any drugs or diagnostic products resulting from our gene
discovery programs will be obtained. The regulatory process can take many years
and require substantial resources. Because some of the products likely to result
from our disease research programs involve the application of new technologies
and may be based upon a new therapeutic approach, they may be subject to
substantial additional review by various government regulatory authorities. As a
result, these authorities may grant regulatory approvals for these products more
slowly than for products using more conventional technologies. Furthermore,
regulatory approval may impose limitations on the use of a drug or diagnostic
product.

     After initial regulatory approval, a marketed product and its manufacturer
are subject to continuing review. Discovery of previously unknown problems with
a product may have adverse effects on our business, financial condition and
results of operations, including withdrawal of the product from the market.

OUR DEPENDENCE UPON A SINGLE THIRD PARTY FOR SEQUENCING MACHINES MAY IMPAIR OUR
RESEARCH PROGRAMS

     We currently use a single manufacturer to supply the gene sequencing
machines that we use in our gene discovery programs. While other types of gene
sequencing machines are available from other manufacturers, we do not believe
that the other machines are as efficient as the machines we currently use. We
cannot be sure that the gene sequencing machines will remain available in
sufficient quantities at acceptable costs. If we cannot obtain additional gene
sequencing machines at commercially reasonable rates, or if we are required to
change to a new supplier of gene sequencing machines, our gene discovery
programs would be adversely affected.

WE MAY NOT BE ABLE TO OBTAIN NECESSARY TECHNOLOGY

     We have acquired or licensed certain components of our technologies from
third parties. Changes in or termination of these third party agreements could
materially adversely affect our discovery or research programs. We cannot be
certain that we will be able to acquire any new technologies which we need.

WE WILL HAVE TO RELY ON OTHERS FOR CLINICAL TRIALS, MANUFACTURING, MARKETING,
REGULATORY COMPLIANCE AND SALES CAPABILITIES, WHICH MAY IMPAIR OUR ABILITY TO
DELIVER PRODUCTS

     In our research collaborations, we will seek to retain rights to develop
and market certain therapeutic and diagnostic products or services. If we are
able to retain these rights and successfully develop products, we expect to
contract with others for conducting clinical trials, manufacturing, marketing
and sales.

     We are not certain that we will be able to enter into such arrangements on
favorable terms, if at all. Our dependence upon third parties for the conduct of
clinical trials, the obtaining of governmental approvals or the manufacture,
marketing or sales of products may adversely affect our ability to develop and
deliver products on a timely and competitive basis. Our current facilities and
staff are inadequate for commercial production and distribution of products. If
we choose in the future to engage directly in the development, manufacturing and
marketing of certain products, we will require substantial additional funds,
personnel and production facilities.

EFFORTS TO REDUCE HEALTHCARE COSTS MAY AFFECT OUR OPERATIONS

     Our success will depend in part on the extent to which government and
health administration authorities, private health insurers and other third party
payors will pay for our products. Reimbursement for newly approved healthcare
products is uncertain. Third party payors, including Medicare in the U.S., are
increasingly challenging the prices charged for medical products and services.
Government and other third party payors are increasingly attempting to contain
healthcare costs by limiting both coverage and the level of reimbursement for
new

                                       17
<PAGE>   19

therapeutic products. We cannot be certain that any third party insurance
coverage will be available to patients for any products we discover or develop.
If government or other third party payors do not provide adequate coverage and
reimbursement levels for our products, the market acceptance of these products
may be materially reduced.

OUR OPERATIONS MAY BE IMPAIRED UNLESS WE CAN SUCCESSFULLY MANAGE OUR GROWTH

     We have recently experienced significant growth in the number of our
employees and the scope of our operations. We intend to hire additional
personnel to construct the IHD and DCDP and to develop our healthcare
informatics products. Our management and operations are, and may continue to be,
under significant strain due to this growth. To manage such growth, we must
strengthen our management team and attract and retain skilled employees. Our
success will also depend on our ability to improve our management information,
research information and operational control systems and to expand, train and
manage our workforce.

USE OF THERAPEUTIC OR DIAGNOSTIC PRODUCTS DEVELOPED AS A RESULT OF OUR PROGRAMS
MAY RESULT IN LIABILITY CLAIMS

     The users of any therapeutic or diagnostic products developed as a result
of our discovery or research programs or the use of our database or medical
decision-support products may bring product liability claims against us. We
currently do not carry liability insurance to cover such claims. We are not
certain that we or our collaborators will be able to obtain such insurance or,
if obtained, that sufficient coverage can be acquired at a reasonable cost. If
we cannot protect against potential liability claims, we or our collaborators
may find it difficult or impossible to commercialize products. A liability claim
or product recall could have a material adverse effect on us.

WE MAY BE UNABLE TO HIRE AND RETAIN THE KEY PERSONNEL UPON WHOM OUR SUCCESS
DEPENDS

     We depend on the principal members of our management and scientific staff,
including Dr. Kari Stefansson, Chairman, President, Chief Executive Officer and
Secretary, Hannes Smarason, Executive Vice President and Senior Business and
Finance Officer, Dr. Jeffrey Gulcher, Vice President, Research and Development
and Dr. C. Augustine Kong, Director of Statistics. If any of these people leaves
us, our ability to conduct our operations may be negatively affected. Our future
success also will depend in part on our ability to attract, hire and retain
additional personnel. There is intense competition for such qualified personnel
and we cannot be certain that we will be able to continue to attract and retain
such personnel. Failure to attract and retain key personnel could have a
material adverse effect on us.

OUR OPERATIONS INVOLVE A RISK OF INJURY FROM HAZARDOUS MATERIALS

     Our research and manufacturing activities involve the generation, use and
disposal of hazardous materials and wastes, including various chemicals and
radioactive compounds. We are subject to laws and regulations governing the use,
storage, handling and disposal of these materials, including standards
prescribed by Iceland and applicable EU standards. Although we believe that our
safety procedures comply with such laws and regulations, the risk of
environmental contamination or injury cannot be eliminated. In the event of such
an occurrence, we could be held liable for any damages that result, which could
exceed our resources. Although we believe that we comply in all material aspects
with applicable environmental laws and regulations and do not expect to make
additional material capital expenditures in this area, we cannot predict whether
new regulatory restrictions on the production, handling and marketing of
biotechnology products will be imposed. Any such new regulatory restrictions
could require us to incur significant costs to comply or could have a material
adverse effect on our operations.

OUR MANAGEMENT HAS BROAD DISCRETION OVER THE USE OF THE PROCEEDS FROM THIS
OFFERING

     The net proceeds of this offering are estimated to be approximately
$   --   million, or about $   --   million if the underwriters exercise their
over-allotment option in full. This calculation is based on an initial public
offering price of $   --   per share. The information contained in this
prospectus regarding our use of these proceeds is based upon the current state
of our business operations, our current business plan and

                                       18
<PAGE>   20

strategy, and current economic and industry conditions. The amount and timing of
our expenditures will vary depending on our progress in developing and
constructing the databases, the progress of our research and discovery programs,
technological changes, changing competitive conditions, and general economic
conditions. The estimated allocations of our use of the net proceeds of this
offering are subject to reapportionment among the listed purposes, and to other
general corporate purposes, including working capital. The actual amount of the
uses of proceeds cannot be predicted with any degree of certainty. Our
management will retain broad discretion as to the allocation of the proceeds of
this offering, including the timing and conditions of the use of the proceeds.

CURRENCY FLUCTUATIONS MAY AFFECT OUR FINANCIAL CONDITION

     Our revenues and cash reserves are denominated in U.S. dollars, but a
portion of our operating costs are denominated in Icelandic kronas. A
strengthening of the Icelandic krona against the U.S. dollar may, therefore,
have a negative impact on our financial condition.

WE DO NOT EXPECT TO PAY DIVIDENDS IN THE FORESEEABLE FUTURE

     We have never paid dividends on our common stock and we do not intend to
pay any dividends on our common stock for the foreseeable future.

YEAR 2000 RISKS MAY HARM OUR BUSINESS

     Despite the passing of January 1, 2000, the risks posed by Year 2000 issues
could still adversely affect our business in a number of significant ways.
Although we believe that our internally developed systems and technology are
Year 2000 compliant, our information technology systems nevertheless could be
substantially impaired or cease to operate due to latent Year 2000 problems.
Additionally, we rely on information technology and automated laboratory
equipment supplied by third parties. Year 2000 problems experienced by us or any
of such third parties could materially adversely affect our business.

THE INTERESTS OF OUR CONTROLLING STOCKHOLDERS MAY CONFLICT WITH OUR INTERESTS
AND THE INTERESTS OF OUR OTHER STOCKHOLDERS

     After this offering, our directors, executive officers and current 5%
stockholders (including an affiliate of Roche), and certain of their affiliates,
will beneficially own approximately  -- % of the common stock. These
stockholders, if they all act together, will then effectively have the ability
to elect all of our directors. They will also be able to determine the outcome
of most corporate actions requiring stockholder approval, including our merger
with or into another company, a sale of substantially all of our assets and
amendments to our certificate of incorporation. The decisions of these
stockholders may conflict with our interests or those of our other stockholders.

OUR RIGHT TO ISSUE PREFERRED STOCK AND ANTI-TAKEOVER PROVISIONS COULD MAKE A
THIRD-PARTY ACQUISITION OF US DIFFICULT AND OTHERWISE ADVERSELY AFFECT COMMON
STOCKHOLDERS

     Our Board of Directors is authorized to designate and issue up to 7,016,666
shares of preferred stock as to which the Board can determine the price, rights,
preferences and privileges of those shares without any further vote or action by
the stockholders. If you own common stock, your ownership rights will be subject
to, and may be adversely affected by, the rights of the owners of preferred
stock that we may issue in the future. As a result, the issuance of preferred
stock could have a material adverse effect on the market value of the common
stock. An additional issuance of preferred stock would give us financial
flexibility for possible acquisitions and other corporate purposes. However, it
could make it more difficult for a third party to acquire a majority of our
outstanding voting stock.

     Further, we are subject to the anti-takeover provisions of Section 203 of
the Delaware General Corporation Law. Under this law, if anyone becomes an
"interested stockholder" in deCODE, we may not enter a "business combination"
with that person for three years without special approval. These provisions
could delay or prevent a change of control. Certain other provisions of our
certificate of incorporation and bylaws, including those

                                       19
<PAGE>   21

providing for preferred stock, could also delay or prevent changes of control or
management. These provisions could adversely affect the market price of the
common stock.

OUR COMMON STOCK HAS NEVER BEEN PUBLICLY TRADED AND WE CANNOT PREDICT THE EXTENT
TO WHICH A TRADING MARKET WILL DEVELOP

     Before this offering, there has been no public market for our common stock,
although some banking institutions in Iceland have been making a market for
privately negotiated transactions among non-U.S. persons in our Series B
preferred stock. Our Series B preferred stock transfer records indicate that
approximately 10 million shares of Series B preferred stock were transferred
during 1999 in approximately 7,000 transactions and approximately 1.1 million
shares of Series B preferred stock were transferred during January 2000 in
approximately 2,700 transactions. The majority of these transactions had an
Icelandic financial institution as one of the counterparties. We cannot predict
the extent to which an active public market for the common stock will develop or
be sustained after this offering. We will negotiate the initial public offering
price with the representatives of the underwriters. The initial public offering
price of our common stock may not be indicative of future market prices.

OUR COMMON STOCK PRICE IS LIKELY TO BE HIGHLY VOLATILE

     The market price of our common stock is likely to be highly volatile. In
addition to various risks described elsewhere in this prospectus, the following
factors could also cause price volatility:

     -  announcements made by us or our competitors concerning the results of
        research activities, technological innovations or new commercial
        products;

     -  changes in or adoption of new government regulations;

     -  regulatory actions;

     -  changes in patent laws;

     -  developments concerning proprietary rights;

     -  variations in operating results; and

     -  actual, announced or threatened litigation.

     Extreme price and volume fluctuations occur in the stock market from time
to time and can particularly affect the prices of technology and biotechnology
stocks. These extreme fluctuations are often unrelated to the actual performance
of the affected issuers. These broad market fluctuations may adversely affect
the market price of our common stock.

FUTURE SALES BY OUR CURRENT STOCKHOLDERS MAY ADVERSELY AFFECT OUR STOCK PRICE
AND OUR ABILITY TO RAISE FUNDS IN NEW STOCK OFFERINGS

     Sales of our common stock by our current stockholders in the public market
after this offering could cause the market price of our stock to fall. Sales may
also make it more difficult for us to sell equity securities or equity-related
securities in the future at a time and price that our management deems
acceptable, or at all. Upon the completion of this offering, we will have
   --   shares of common stock outstanding, assuming no exercise of options or
warrants and assuming no exercise of the underwriters' over-allotment option. Of
these outstanding shares of common stock, the    --   shares sold in this
offering will be freely tradable, without restriction under the Securities Act
of 1933, as amended (the "Securities Act"), unless purchased by our
"affiliates." The remaining    --   shares of common stock held by existing
stockholders are "restricted securities" and may be resold in the United States
public market only if registered or pursuant to an exemption from registration.

     Immediately following the completion of this offering, holders of  --
shares of common stock and options, and warrants to purchase  -- shares of
common stock will be entitled to certain registration rights. Upon registration,
these shares may be freely sold in the public market.

                                       20
<PAGE>   22

     Stockholders who will hold an aggregate of  -- % of our common stock after
the offering have agreed, pursuant to certain lock-up agreements, that they will
not sell any shares of common stock for a period of 180 days after the date of
this prospectus without the prior written consent of the underwriters.

     Shareholders who will hold an aggregate of  -- % of our common stock after
the offering have signed an agreement providing that, upon request of deCODE or
the underwriters, they will not sell any shares of common stock for a period
ending 180 days after the effective date of the registration statement of which
this prospectus is a part.

     Upon expiration of the lock-up agreements:

     -   -- shares of common stock will be immediately eligible for resale
        (subject to the volume limitations of Rule 144 in the case of sales by
        affiliates);

     -   -- shares of common stock will be immediately eligible for resale
        (subject to the volume limitations of Rule 144); and

     -   -- shares of common stock will be eligible for resale from time to time
        thereafter upon expiration of the applicable holding periods under Rule
        144 (subject to the volume limitations of Rule 144).

PURCHASERS IN THIS OFFERING WILL SUFFER IMMEDIATE DILUTION

     If you purchase common stock in this offering, the value of your shares
based upon our actual book value will immediately be less than the offering
price you paid (known as "dilution"). Based upon the net tangible book value of
the common stock at December 31, 1999, your shares will be worth $   --   less
per share than the price you paid in the offering. If options and warrants we
previously granted are exercised, additional dilution is likely to occur.
Following the completion of this offering, options and warrants to purchase
2,125,037 shares of common stock, at the weighted-average exercise price of
$   --   will be outstanding.

                                       21
<PAGE>   23

                                USE OF PROCEEDS

     We estimate that we will receive net proceeds from this offering of about
$   --   million, or about $   --   million if the underwriters exercise their
over-allotment option in full. For purposes of this calculation, we have assumed
an initial public offering price of $   --   per share.

     We expect to use approximately $   --   million of the net proceeds of this
offering for the development and construction of the DCDP. In addition, we
intend to spend approximately $   --   million to fund our discovery and
research programs.

     We also intend to spend approximately $   --   million of the net proceeds
of this offering for capital expenditures. These expenditures will include the
purchase of:

     -  laboratory automation equipment;

     -  production equipment;

     -  computer equipment;

     -  furniture;

     -  fixtures; and

     -  additional office and laboratory facilities.

     The remainder of the net proceeds are expected to be used for working
capital and general corporate purposes. We may also use a portion of the net
proceeds to acquire businesses, technologies, or products complementary to our
business even though we do not currently have any specific plans to do so.

     Pending use of the net proceeds for the purposes described above, we intend
to invest the net proceeds in short-term, interest-bearing, investment-grade
securities.

<PAGE>   24

                                DIVIDEND POLICY

     We have never declared or paid any dividends on our common stock. Following
this offering, our dividend practices with respect to our common stock will be
determined and may be changed from time to time by our Board of Directors. Any
issuance of dividends will be based upon our earnings, financial condition,
capital requirements and other factors considered important by our Board of
Directors. Under Delaware law and our certificate of incorporation, our Board of
Directors is not required to declare dividends on our common stock. We expect to
retain all earnings, if any, generated by our operations for the development and
growth of our business and do not anticipate paying any dividends to our
stockholders for the foreseeable future.

     Each share of our outstanding classes of preferred stock bears dividends at
the rate of 8% of the original purchase price per share, payable when declared
by the Board of Directors. To date, the Board of Directors has not declared any
dividends on the preferred stock. Our certificate of incorporation provides that
all the outstanding preferred stock will convert to common stock upon the
closing of this offering, at which time all undeclared dividends will be
canceled.

                                 CAPITALIZATION

     The following table shows as of December 31, 1999: our actual
capitalization; our pro forma capitalization after giving effect to the
automatic conversion upon the closing of this offering of our Series A preferred
stock, Series B preferred stock and Series C preferred stock; and our pro forma
capitalization as adjusted to give effect to that automatic conversion and the
sale of    --   shares of our common stock pursuant to this offering. This
information assumes an initial public offering price of $   --   per share less
the estimated underwriters discounts and commissions. For information pertaining
to our common stock and our preferred stock, see "Description of Securities."

                                    DILUTION

     If you invest in our common stock, your interest will be diluted to the
extent of the difference between the public offering price per share of our
common stock and the pro forma as adjusted net tangible book value per share of
common stock after this offering. Pro forma net tangible book value per share
represents the amount of our total tangible assets less total liabilities,
divided by the pro forma number of shares of common stock outstanding. As of
December 31, 1999, our pro forma net tangible book value was approximately
$   --   or $   --   per share of common stock after taking into account the
issuance of    --   shares of common stock upon the automatic conversion, upon
the closing of this offering, of our Series A preferred stock, Series B
preferred stock and Series C preferred stock. Without taking into account any
other changes in our net tangible book value after December 31, 1999, other than
to give effect to this offering of    --   shares of common stock at an assumed
initial offering price of $   --   per share, less estimated underwriting
discounts and commissions, our pro forma as adjusted net tangible book value, at
December 31, 1999, would have been approximately $   --   or $   --   per share.
This represents an immediate increase in the net tangible book value of
$   --   per share of our common stock to present stockholders and an immediate
dilution of $   --   per share or  -- % of the initial public offering price to
new investors. The following table shows this dilution:

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

     You should read this section in conjunction with our consolidated financial
statements and related notes thereto appearing elsewhere in this prospectus.

OVERVIEW

     deCODE was incorporated in August 1996. We have incurred losses since our
inception, principally as a result of research and development and general and
administrative expenses in support of our operations. On December 31, 1999, we
had an accumulated deficit of $76,713,517. We anticipate incurring additional
losses over at least the next several years as we expand our internal and
collaborative gene discovery efforts, continue our technology development and
construct the DCDP and healthcare informatics. We expect that our losses will
fluctuate from quarter to quarter and that such fluctuations may be substantial
especially because progress in our scientific work and milestone payments which
are related to progress can fluctuate between quarters.

     In February 1998, we entered into a research collaboration and
cross-license agreement with Roche regarding research into the genetic causes of
twelve diseases. Under the terms of the agreement, Roche has made equity
investments and is funding our gene discovery programs in the twelve diseases.
For the year ended December 31, 1999, revenues from Roche constituted 96% of our
total revenues. See "Business."

     We anticipate that collaborations will remain an important element of our
business strategy and future revenues. Our ability to generate revenue growth
and become profitable is dependent, in part, on our ability to enter into
additional collaborative arrangements, and on our ability and our collaborative
partners' ability to successfully commercialize products incorporating, or based
on, our work. There can be no assurance that we will be able to maintain or
expand our existing collaborations, enter into future collaborations to develop
applications based on existing or future research agreements or successfully
commercialize the DCDP.

     Our failure to successfully develop and market products over the next
several years, or to realize product revenues, would have a material adverse
effect on our business, financial condition and results of operations. Royalties
or other revenues generated from commercial sales of products developed using
our technologies are not expected for at least several years, if at all. We
currently only have an agreement with Roche which provides all of our
collaborative research funding.

     Our operating results through December 31, 1999 reflect the expenses
incurred in our gene discovery activities, partly offset by the revenues
received pursuant to our research collaboration agreement with Roche in
connection with these activities. During 2000 we will continue these activities,
but our operating results will also reflect the substantial costs we expect to
incur in commencing the development of the IHD and the DCDP. While we intend to
enter into collaborations to help fund and develop the DCDP, until we do so
there will be no revenue from our database service activities to offset against
these costs.

     On December 3, 1999, the staff of the Securities and Exchange Commission
issued Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial
Statements" (SAB 101), that summarizes the staff's views in applying generally
accepted accounting principles to revenue recognition in financial statements.
The accounting and disclosure requirements that are described in SAB 101 apply
to all registrants. deCODE has adopted the requirements of SAB 101 and has
restated prior years in accordance with the going public exemption under
Accounting Principles Board Opinion No. 20, "Accounting Changes."

RESULTS OF OPERATIONS

     COMPARISON OF YEARS ENDED DECEMBER 31, 1999 AND 1998

     Revenues.  Our revenues increased to $16,444,075 for the year ended
December 31, 1999 as compared to $12,705,000 for the year ended December 31,
1998, an increase of 29%. The increase was primarily due to revenues related to
milestone payments received pursuant to our research collaboration agreement
with Roche; the increase also reflected the recognition of twelve months of
research funding provided by Roche in 1999

                                       28
<PAGE>   30

compared to eleven months in 1998, and the receipt of laboratory equipment and
consumables from Affymetrix in the first fiscal quarter of 1999 as consideration
for services provided by us on its behalf.

     Research and Development.  Our research and development expenses increased
to $31,823,950 for the year ended December 31, 1999 as compared to $19,282,364
for the year ended December 31, 1998, an increase of 65%. This increase was
primarily attributable to the continued expansion of operations including our
hiring of additional research personnel and the resulting salary and benefits
costs, an expansion of our laboratory facility and the resulting depreciation,
and our increased research efforts.

     General and Administrative.  Our general and administrative expenses
increased to $7,863,299 for the year ended December 31, 1999 as compared to
$4,893,202 for the year ended December 31, 1998, an increase of 61%. This
increase was principally attributable to the increase in personnel and related
salaries and benefits costs.

     Stock Compensation Expense.  Stock compensation expense was $8,043,995 for
the year ended December 31, 1999 compared to $5,219,642 for the year ended
December 31, 1998, an increase of 54%. This increase was attributable to
expenses for options and shares awarded to employees and others with exercise or
purchase prices below the deemed fair value for financial reporting purposes.

     Equity in Net Earnings (Loss) of Affiliate.  deCODE's equity in net
earnings (loss) of affiliate, Gagnalind hf., for the year ended December 31,
1999 is comprised of deCODE's share of the earnings of Gagnalind hf. and
amortization of the difference between deCODE's cost and the underlying equity
in the net assets of Gagnalind hf. at acquisition.

     Interest Income, net.  Our interest income increased to $2,185,441 for the
year ended December 31, 1999 as compared to $922,230 for the year ended December
31, 1998, an increase of 137%. This increase primarily derived from interest on
payments received in connection with a stock issuance. The increase was also
attributable to increased cash reserves resulting from milestone payments
pursuant to our research collaboration agreement with Roche. Our interest
expenses increased to $635,959 for the year ended December 31, 1999 as compared
to $359,894 for the year ended December 31, 1998, an increase of 77%. This
increase in interest expense primarily resulted from new equipment leasing
arrangements which we entered into in the second half of 1998 and were in effect
for all of 1999.

     Net Loss.  As a result of the foregoing factors, our net loss for the year
ended December 31, 1999 increased to $23,177,774 as compared to $10,908,230 for
the year ended December 31, 1998, an increase of 112%. As of December 31, 1999,
we had accumulated losses of $76,713,517 and did not owe any federal income
taxes. Realization of deferred tax assets is dependent on future earnings if
any.

     Net Loss Available to Common Stockholders. Our net loss available to common
stockholders more than quadrupled to $61,607,605 for the year ended December 31,
1999 as compared to $13,479,753 for the year ended December 31, 1998. This
increase was primarily due to increases in the above described costs and
expenses over the same period and to the increase in accrued dividends and
amortized discount on preferred stock and premiums on the repurchase of
preferred stock.

     COMPARISON OF YEARS ENDED DECEMBER 31, 1998 AND 1997

     Revenues.  Our revenues were $12,705,000 for the year ended December 31,
1998. We did not have any revenues for the year ended December 31, 1997.
Revenues in 1998 were solely attributable to payments received pursuant to our
research collaboration agreement with Roche.

     Research and Development.  Our research and development expenses more than
tripled to $19,282,364 for the year ended December 31, 1998 from $6,080,096 for
the year ended December 31, 1997. This increase was primarily attributable to
continued expansion of our operations, including our hiring of more research and
development personnel, purchases of laboratory supplies, investment in
laboratory equipment and expansion of our facilities.

     General and Administrative.  Our general and administrative expenses more
than doubled to $4,893,202 for the year ended December 31, 1998 from $1,967,684
for the year ended December 31, 1997. This increase was primarily attributable
to the increase in personnel and related salaries and benefits costs.
                                       29
<PAGE>   31

     Stock Compensation Expense.  Stock compensation expense was $5,219,642 for
the year ended December 31, 1998, compared to $11,851 for the year ended
December 31, 1997. This increase was attributable to expenses for options and
shares awarded to employees and others with exercise or purchase prices below
the deemed fair value for financial reporting purposes.

     Interest Income, net.  Our interest income increased more than five-fold to
$922,230 for the year ended December 31, 1998 from $163,076 for the year ended
December 31, 1997. This increase was due to greater cash reserves primarily
resulting from our sale of Series B preferred stock to Icelandic investors in
1998 and also from payments received pursuant to our research collaboration and
stock purchase agreements with Roche. Our interest expense increased to $359,894
for the year ended December 31, 1998 from $171,537 for the year ended December
31, 1997, an increase of 110%. This increase was mainly due to additional
equipment lease obligations entered into during 1998, which enabled us to
support our research and development activities.

     Net Loss.  As a result of the foregoing factors, our net loss for the year
ended December 31, 1998 increased to $10,908,230 as compared to $8,056,241 for
the year ended December 31, 1997, an increase of 35%. As of December 31, 1998,
we had accumulated losses of $20,275,235 and did not owe any federal income
taxes. Realization of deferred tax assets is dependent on future earnings if
any.

     Net Loss Available to Common Stockholders. Our net loss available to common
stockholders increased to $13,479,753 for the year ended December 31, 1998 as
compared to $8,676,626 for the year ended December 31, 1997, an increase of 55%.
This increase was primarily due to increases in the above-described costs and
expenses over the same period and to the increase in accrued dividends and
amortized discount on preferred stock.

     LIQUIDITY AND CAPITAL RESOURCES

     Our cash and cash equivalents totalled $29,668,249 at December 31, 1999. We
have financed our operations since inception primarily through private
placements of equity securities, our collaboration with Roche and capital
leases. As of December 31, 1999, we had received an aggregate of $39,053,695
pursuant to our collaboration agreement with Roche in fixed research funding,
milestone payments and equity contributions. Inflation has not had a material
effect on our business.

     Our investing activities have consisted of the acquisition of an office and
laboratory facility in Reykjavik, Iceland, acquisitions of equipment and
expenditures for building improvements. At December 31, 1999, our gross
investment in office and laboratory space, equipment and building improvements
since inception was $17,802,672. In addition, during 1999, deCODE acquired an
approximate 56% equity interest in Gagnalind hf., an Icelandic software company,
in exchange for cash and shares of our common stock and Series B preferred
stock.

     In February and March 1999, we sold 110,000 shares of Series B preferred
stock resulting in aggregate cash proceeds of $825,000. In February and May
1999, we sold 1,111,111 shares of Series C preferred stock and 111,111 warrants
to purchase shares of Series C preferred stock for an aggregate purchase price
of $3,333,445. In August 1999, we repurchased a total of 2,358,074 shares of
Series A preferred stock, issued and subsequently repurchased 250,000 shares of
Series B preferred stock in exchange for 333,333 shares of common stock and
repurchased 100,000 shares of Series C preferred stock, at an initial purchase
price of $7.50 per share, later adjusted upward to $13.95 per share. In August
1999 we issued 5,000,000 shares of Series B preferred stock at an initial
purchase price of $7.50 per share, later adjusted upward to $15.00 per share.

     The net cash used in our operating activities was $11,646,931 for the year
ended December 31, 1999 compared to $2,067,278 for the year ended 1998. The
increase was primarily due to higher research and development costs which were
only partly offset by payments from Roche.

     As of December 31, 1999, we had net operating losses carried forward of
approximately $18,867,000 to offset Icelandic and U.S. taxable income. If not
utilized, the net operating loss carry-forwards will begin to expire in the year
2004 in Iceland and in the year 2018 in the United States.

     We had no material commitments for capital expenditures at December 31,
1999. We anticipate that the net proceeds from this offering will enable us to
increase capital expenditures over the next several years to expand

                                       30
<PAGE>   32

our facilities and purchase additional equipment in support of additional
collaborations, increased internal research and development and development of
the DCDP.

     We expect our cash requirements to increase significantly in future periods
because of planned expansion of our operations. The planned expansion will be in
support of expected growth in research collaboration agreements, database
construction, and internal research and discovery programs. We believe that the
net proceeds from this offering, together with existing cash and cash
equivalents, and anticipated cash flows under our research collaboration
agreement with Roche, will be sufficient to support our operations through at
least 2001. Our belief is based on our current operating plan, which could
change in the future and require additional funding sooner than anticipated.
Even if we have sufficient cash for our current operating plan, we may seek to
raise additional capital because of favorable market conditions or other
strategic factors.

     Our future capital requirements depend on numerous factors, including:

     -  the progress of our discovery and research programs;

     -  the number and breadth of these programs;

     -  our ability to attract collaborators for, subscribers to or customers
        for our products and services;

     -  our achievement of milestones under our research collaboration agreement
        with Roche;

     -  our ability to establish and maintain additional collaborations;

     -  our collaborators' progress in commercializing our gene discoveries;

     -  the level of our activities relating to commercialization rights we
        retain in our collaborations;

     -  competing technological and market developments;

     -  the costs involved in enforcing patent claims and other intellectual
        property rights; and

     -  the costs and timing of regulatory approvals.

     We will require significant additional capital in the future, which we may
seek to raise through public or private equity offerings, debt financing or
additional collaborations and licensing arrangements. No assurance can be given
that additional financing or collaborations and licensing arrangements will be
available when needed, or that if available, will be obtained on favorable
terms. If adequate funds are not available when needed, we may have to curtail
operations or attempt to raise funds on unattractive terms. See "Risk
Factors -- We may not be able to obtain sufficient additional funding to meet
our expanding capital requirements."

     IMPACT OF CURRENCY FLUCTUATIONS

     We publish our consolidated financial statements in U.S. dollars. Currency
fluctuations can affect the financial results of deCODE as revenues and cash
reserves are in U.S. dollars but a portion of operating costs are in Icelandic
kronas. A strengthening of the Icelandic krona against the dollar can thus
adversely affect the "buying power" of our cash reserves and revenues. On the
other hand, weakening of the Icelandic krona can strengthen our financial
position. All long-term liabilities are U.S. dollar denominated. deCODE has not
previously engaged in, and does not now contemplate entering into, currency
hedging transactions. deCODE may enter into such transactions on a
non-speculative basis to the extent that it may in the future have substantial
foreign currency exposure, for example, in connection with payments from
collaborative partners or due to investments.

     RECENT ACCOUNTING PRONOUNCEMENT

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities." This standard establishes a new model for accounting
for derivatives and hedging activities and supersedes and amends a number of
existing standards. Upon the standard's initial application, all derivatives are
required to be recognized in the balance sheet as either assets or liabilities
and measured at fair value. In addition, all hedging relationships must be

                                       31
<PAGE>   33

designated, reassessed and documented. Currently, the standard is to be
effective for fiscal years and quarters beginning after June 15, 2000.
Considering deCODE's current activities, it is not anticipated that the adoption
of the new standard will have a significant impact on deCODE's financial
position or results of operations.

     QUANTITATIVE AND QUALITATIVE DISCLOSURES

     The primary objective of our investment activities is to preserve principal
while maximizing income we receive from our investments without significantly
increasing risk. Some of the securities in our investment portfolio may be
subject to market risk. This means that a change in prevailing interest rates
may cause the market value of the investment to fluctuate. For example, if we
hold a security that was issued with a fixed interest rate at the
then-prevailing rate and the prevailing interest rate later rises, the market
value of our investment will probably decline. To minimize this risk in the
future, we intend to maintain our portfolio of cash equivalents and short-term
investments in a variety of securities, including commercial paper, money market
funds and government and non-government debt securities. In general, money
market funds are not subject to market risk because the interest paid on such
funds fluctuates with the prevailing interest rate. As of December 31, 1999, all
of our cash and cash equivalents were in money market and checking accounts.

     THE IMPACT OF THE YEAR 2000

     We started our operations in 1996 and do not expect the Year 2000 problem
to have a significant impact on our information technology infrastructure or the
gene sequencing machines and other equipment contained in our laboratory. We
have received assurances from our vendors that their products are Year 2000
compliant and we are not aware of any problems which developed after January 1,
2000. Currently, we are not aware of any Year 2000 problems within deCODE. Given
the fact that all our hardware and software is relatively new, we have not
performed extensive testing except where we were not able to obtain assurance
from a provider or had reason to believe that a product might have Year 2000
problems.

                                    BUSINESS

OVERVIEW

     deCODE is a genomics and health informatics company which is developing
products and services for the healthcare industry. We develop and apply modern
informatics technology to discover new knowledge about health and disease
through data-mining. We believe that certain unique qualities of the Icelandic
population, together with our advanced bioinformatics and high throughput
genotyping facility, should place deCODE at a competitive advantage to perform
genetic and medical research to identify disease genes and drug and diagnostic
targets. As the international effort to sequence the human genome progresses, we
believe that the principal task will be to transform raw genomic data into
knowledge about human health and disease and then into tangible products and
services. We believe that deCODE, is well-positioned to place the human genome
sequence in a meaningful context through which we and our partners can generate
value.

     deCODE was founded in 1996 and its operations, as well as its approximately
300 employees, are based in Iceland. In 1998, we entered into a significant
research collaboration and cross-license agreement with Roche, under which we
may receive a total of more than $200 million in research funding and milestone
payments. To date our accomplishments include:

     -  the identification of eight locations for disease-causing genes;

     -  the identification of twelve specific candidate disease genes;

     -  the achievement of four milestones in our research collaboration
        agreement with Roche;

     -  the completion of a high-throughput genotyping facility;

     -  the development of automated software algorithms for data capture,
        analysis and interpretation; and

     -  near completion of a computerized genealogy database covering the
        Icelandic population.

     We believe that discovery of healthcare knowledge requires bringing
together three key types of data: information from the healthcare system,
information about relationships among individuals covered by this system and
associated molecular genetics data. We believe that operating in Iceland
accomplishes this by allowing us to benefit from the following four important
characteristics of the Icelandic nation in our medical and genetic research:

     -  extensive genealogical records dating back to the settlement of the
        country in the ninth century;

     -  relative genetic homogeneity with a population descended from a small
        number of settlers;

     -  a centralized healthcare system since 1915; and

     -  a well-educated population.

     We believe that bringing these four factors together greatly enhances our
research and development efforts in generating future products and services for
the healthcare industry.

                                       33
<PAGE>   35

     The following diagram illustrates our business model:

                                [BUSINESS MODEL]

     Our business model is based on four sets of information:

     -  genealogy records of almost all living Icelanders and most of their
        ancestors for whom records exist, dating back to the settlement of
        Iceland in the ninth century;

     -  genotype data from consenting Icelanders;

     -  the IHD, which we plan to create and operate from healthcare records of
        Icelanders pursuant to the IHD license; and

     -  other public and proprietary data to which we have access.

     Our three avenues of commercialization are as follows:

     Discovery Services.  We believe that the development and application of
proprietary bioinformatics tools in the context of an appropriate population
will accelerate our ability to discover disease-related genes and associated
drug targets. This strategy is designed to enable us to derive value both from
diagnostic and therapeutic products and from pharmacogenomic services. We are
currently working on discovery in collaboration with Roche and in our own
research programs. We expect to seek additional partners for this business unit
from among pharmaceutical and biotechnology companies.

     Database Services.  We are in the early stages of developing the DCDP, a
tool which, subject to ongoing compliance with regulatory requirements, will
cross-reference genealogical records, data from the IHD and genotypes of
consenting participants. The DCDP is intended to generate knowledge about
diseases and their genetic risk factors, disease management, and to provide
insights into the interplay between environment and disease, outcomes and
resource use in delivering healthcare. deCODE believes that the DCDP will be
unique both in cross-referencing genetic and healthcare information and in
providing an unprecedented level of detail of the interplay between genes,
environment and disease. As more information is generated, both inside and
outside deCODE, we believe that the DCDP will become even more powerful. We
anticipate that the customer base for the DCDP will include a variety of
participants in the healthcare industry, such as pharmaceutical and
biotechnology companies and healthcare providers.

     Healthcare Informatics.  The third unit of our business, healthcare
informatics, is derived from our discovery and database services. The products
being developed by this business unit are expected to result from
                                       34
<PAGE>   36

knowledge and experience acquired in our two principal business units, discovery
services and database services. In the future, the integration of genetics and
medicine will add a new level of complexity to the decision making process in
the delivery of healthcare. The need for medical decision-support systems, or
MDSS, for healthcare providers is expected to increase over the next several
years. We are developing MDSS, which will include insights from the DCDP, for
healthcare providers and we will seek to commercialize bioinformatics tools
developed in our gene and drug target discovery efforts. We also plan to provide
privacy protection products based on our expertise in encryption tools for
complex and sensitive medical and genetic data.

SCIENTIFIC BACKGROUND

     The map of the human genome is about to be unraveled. In December 1999, the
sequence of the entire chromosome 22 was announced and the sequences of other
chromosomes are expected to follow. The target of the Human Genome Project is to
complete the first draft sequence of the human genome by May 2000. The challenge
will then be to transform this raw sequence data into specific knowledge about
disease and healthcare.

     GENOMICS

     The blueprint of all biological activity, which consists of
deoxyribonucleic acid, or DNA, is located within the nucleus of every cell and
is commonly referred to as the genome. The genome is the total DNA content of an
organism. DNA is composed of four bases. The sequence or order of these bases is
the code that ultimately determines structure and function in all organisms. The
human genome is broken up into 23 pairs of chromosomes and every individual
inherits a set of 23 chromosomes from each parent. Genes are segments of DNA
located throughout the genome. The human genome consists of approximately three
billion bases and is estimated to contain more than 100,000 genes. Each cell
uses or "expresses" only those genes (approximately 10% of the 100,000 genes)
necessary for its specific role. Accordingly, different types of cells express
different sets of genes.

     When a gene is turned on or expressed, it produces a derivative copy of its
DNA sequence called messenger RNA, which is used as a template to direct the
production of a protein. Proteins are large molecules composed of amino acids
and control all biological processes. The order of the bases in DNA determines
the order of amino acids in a protein. Proteins in turn make up molecular
pathways, which cells use to carry out their specific functions. Diseases can
occur when a molecular pathway in a normal biological function is upset or
blocked as a result of a mutated or a defective gene. The ability to detect a
mutation and to understand the process by which it contributes to disease is
crucial to understanding the fundamental mechanisms of a disease. In the
simplest form, genetic diseases result from a mutation in only one gene and the
disease is usually passed from generation to generation. Common diseases are
thought to have a complex genetic basis; they generally skip one or more
generations and may result from interactions between genes or from the
interaction between genetic and environmental factors.

     Soon, the entire human genome sequence will be discovered. We believe that
by itself, this knowledge is of limited value and that the importance of this
discovery will only reach its full potential if this sequence data is explored
along with detailed knowledge about health history, genetic profile and
genealogy.

     POPULATION GENOMICS

     Population genomics is a field of genomics which applies modern genetic and
molecular biology techniques to an entire population to discover how genetic
factors contribute to the cause of diseases. Since almost all common diseases
have a genetic component, the discovery of the cause of disease can often be
reduced to finding the gene or genes mutated in patients who have the disease as
compared to those who do not. Since this approach does not require a
preconceived notion about which tissues or proteins or genes are important in
the disease, it represents a systematic strategy for creating specific knowledge
about disease. The challenge is to find a population which is small enough to
allow the necessary cooperation but large enough to deliver meaningful results.

                                       35
<PAGE>   37

     FUNCTIONAL GENOMICS

     Functional genomics is a field of genomics that attempts to determine the
manner in which disease genes specifically impact the disease process. It is the
study of the function of genes, including how expression of a particular gene is
regulated and the function of the protein that the gene encodes. Researchers
employing functional genomics techniques may analyze large numbers of genes to
compare patterns of gene expression in diseased and healthy tissues or may
compare genes in humans to those in other species, in each case in an effort to
determine the molecular pathways that cause disease.

     GENOMICS AND HEALTHCARE PRODUCTS

     Genomics and Diagnostics.  Gene-based diagnostic tests for both disease
identification and management represent an important tool that can be used by
physicians to identify and monitor patients with increased risk of a disease.
These tests can complement clinical tests and may lead to more cost-effective
use of expensive tests and to a greater level of accuracy. Knowledge of
predisposition towards a disease may allow patients to alter their lifestyles or
to take medication that prevents the disease.

     Genomics and Therapeutics.  The lack of precise knowledge about the causes
of diseases makes it difficult for the pharmaceutical industry to select targets
for new drugs. Identifying specific disease genes may result in very specific
and, therefore, potentially more valuable drug targets than are otherwise
available. The disease gene products themselves may be attractive drug targets.
In addition, they mark a key molecular pathway that is composed of several other
potential drug targets.

     Genomics and Drug Response.  The efficacy and safety of existing and new
drugs may be enhanced by pharmacogenomics. Pharmacogenomics is the application
of genomics technology to the analysis and identification of genes involved in
drug response. It is believed that genomics will permit the identification of
the genetic differences that cause different people to respond differently to
the same drugs. This may lead to tailor-made treatments for individuals,
maximizing efficacy and minimizing side effects.

DECODE'S UNIQUE APPROACH

     POPULATION GENOMICS AND THE VALUE OF THE ICELANDIC POPULATION

     We believe that our unique approach, coupled with the application of
extensive bioinformatics to population genomics, has a number of distinct
advantages because of the following characteristics of the Icelandic nation:

     Extensive Genealogy.  Genealogy has been a national pastime in Iceland
since the country was settled in the ninth century. Numerous sources of
genealogical information, including parish records, census data and written
manuscripts, are readily available.

     Relative Genetic Homogeneity.  Common diseases in most countries have a
large number of genetic causes. In an isolated population that is genetically
simpler, the number of genetic causes is likely to be fewer than in more
genetically diverse populations. Thus, studying a more homogeneous population,
like the Icelanders, simplifies the problem of finding and subsequently
understanding disease genes and mutations causing common diseases. The Icelandic
population was founded by Norwegian and British settlers who arrived in Iceland
in the ninth and tenth centuries. Because Iceland has experienced little
immigration over the last eleven centuries, most of the 275,000 living
Icelanders are descended from these original "founding" settlers. Our ability to
trace the Icelandic population back approximately 1,100 years also facilitates
gene discovery. Because many present-day Icelanders may share a particular
disease gene with one of the founding settlers, they may also have such disease
gene in common with other Icelanders. We can make use of this "founder" effect
to facilitate the identification of disease genes. It has been demonstrated that
the disease genes found in Iceland are, in general, also found in other
populations. Even if the disease genes in Iceland are different from those found
in other populations, the identification of any disease gene marks a key
molecular pathway likely to be involved in the disease in other populations as
well. Therefore, we believe the discovery of a disease gene in Iceland may
enhance the identification of drug targets for any population.

                                       36
<PAGE>   38

     Centralized Healthcare System.  Iceland has had a centralized national
healthcare system since 1915. It presently consists of a base of 55 primary care
centers, two major hospitals in Reykjavik which are being merged, one central
hospital in Akureyri, and several smaller ones. Outside the primary care
centers, the healthcare system is highly specialized and patients with most of
the major illnesses are cared for by specialty clinics. Our clinical
collaborators work at these centers, as well as in the major hospitals.

     Well-educated Population.  The level of public education is high in Iceland
and illiteracy is negligible. Historically, the Icelandic population has been
cooperative when approached by physicians and scientists working on biomedical
research in the Icelandic community.

     DISCOVERY SERVICES

     The extensive genealogy database and associated bioinformatics that we have
built in Iceland are the core of our novel genealogical approach to identifying
human disease genes and associated drug targets.

     We believe that working with the Icelandic population puts us in a position
to accelerate the discovery and development of new proprietary diagnostic and
therapeutic products capable of addressing diseases at their root causes, rather
than simply identifying and treating their symptoms. These programs may permit
doctors to make earlier diagnoses, use healthcare resources more
cost-effectively and select safer and more effective drugs for patients on the
basis of their genetic make-up.

     The genealogical approach that we have developed depends on the
genealogical database and bioinformatics tools that we have built. In the study
of any particular disease, we first define the disease classification broadly
but rigorously. (For example, we first labeled stroke patients as "stroke"
rather than as a series of less common subtypes of stroke). After our clinical
collaborators compile a list of all patients who have been diagnosed with the
disease, the list is encrypted and run through our genealogy database which
yields very large extended families of patients, sometimes containing hundreds
of individuals. The genealogy naturally links together those patients who are
likely to share a gene or genes for the disease. The patients are genotyped to
determine which genes or pieces of chromosomes they have in common. The
genealogical approach compensates for the inadequacies of "consensus criteria"
for disease classification, which utilizes specific symptoms accepted by a
consensus committee of physicians to determine who is "affected" by the disease,
and increases the chance that the form of the disease studied is the one
actually inherited. We believe that no other organization uses genealogy in this
manner. Our unique approach to human genetics has allowed us to map genes in
diseases in which many others have previously failed. By using this approach,
deCODE expects to be able to assign function to the raw data contained in the
human genome sequence.

     The following diagram describes our approach to gene discovery. A
description of each step and a list of supporting tools and technologies used in
each step follows the diagram.

<PAGE>   39

     Genetic Mapping

     We have developed an extensive computerized genealogy database that
currently includes almost all 275,000 living Icelanders along with most of their
ancestors for whom records exist. This represents most of the Icelanders who are
known through records ever to have lived in Iceland. We believe that this is the
most complete genealogy database of any nation. We have shown that the accuracy
of maternal connections in the database is greater than 99.3%.

     Before we start a study looking for genes that cause or contribute to a
particular disease, we obtain approvals from both the Bioethics Committee and
the Data Protection Commission. All patients who participate in our research
program by giving a blood sample sign an informed consent form approved by the
Bioethics Committee. We have developed a sophisticated encryption system to
protect the personal privacy of all participating volunteers.

     In our present disease-based research projects the first step of our
genealogical approach is for our clinical collaborators to compile a list of
patients who have been diagnosed with a particular disease in Iceland. After the
Data Protection Commission has encrypted the patient list, it is sent to us and
run through an encrypted version of our genealogy database. The genealogy
database and associated data-mining tools that we have developed enable us to
determine the relationships among all members of a large patient list and
demonstrate information flow through the generations.

     Using DNA from patients and their relatives who grant us informed consent,
we are able to generate high-resolution genotypes with our high-throughput
genotyping facility using 1,000 microsatellite markers. A microsatellite marker
is a segment of DNA containing variable short repeats that can be used to derive
a genotype. Our high-throughput genotyping facility and bioinformatics systems
substantially decrease the amount of labor involved in reading the genotypes.

     We have developed a statistical informatics program that is used to
determine which portion of the genome is shared among most or all of the
patients within a family. This technique can systematically screen every segment
of the human genome for shared genotypes and can narrow the location of a
disease gene or genes to a small fraction (1/1000) of the human genome. That
segment marks the location of the disease gene that is mutated in the patients
with the disease. We use stringent criteria to determine that we have
successfully found a disease gene location before moving onto the next step of
gene discovery.

     Physical Mapping, Fine-Mapping, and Sequencing

     Once the chromosomal region containing the disease gene has been narrowed
to two to three million base pairs, a higher resolution map is developed. To
accomplish this, we construct a physical map using large overlapping pieces of
human DNA. We have developed an automated high-throughput physical mapping
method which is based on sophisticated proprietary software developed at deCODE
and uses robotics. By integrating a robust hybridization system (i.e., matching
of a small piece of DNA to large segments of DNA), automated analysis of the
hybridization data, and data-mining techniques, we construct low-resolution and
high-resolution maps of the human genome spanning from 30 to 80 million bases.

     We use low-resolution and high-resolution physical maps to find new
microsatellite markers and genetic variations known as single
nucleotide-polymorphisms, or SNPs, and use them to create more precise sets of
genotypes of the patients. SNP markers differ from microsatellite markers in
several ways. SNPs represent a single base change in the genomic sequence and
microsatellite markers represent short repeats of sequence. There is more
information contained in microsatellite markers than SNPs (one microsatellite
marker contains three to five times more information than a SNP) and so they are
well-suited for our genetic studies using large families. Currently, the cost of
genotyping microsatellite markers is much less than genotyping SNPs (especially
given the relative information content). However, the SNPs are more numerous
than microsatellite markers and therefore more useful for fine-mapping and
association studies.

     Many patients may share several closely spaced genotypes which serve to
narrow the region containing a disease gene. We believe that the relative
genetic homogeneity and the age of the Icelandic population will enable us to
reduce the size of the chromosomal region containing the disease gene to as few
as 250,000 base pairs. We
                                       38
<PAGE>   40

believe that this segment would contain fewer than ten candidate genes, thus
reducing the amount of time required to screen the genes for mutations.

     Once we have narrowed a region, we sequence this narrow region using
automated DNA sequencers and then use our bioinformatics tools to identify new
genes. The genes are screened in turn for mutations that occur in patients with
the disease and rarely in those without. Typically, only one gene in this
segment will be the disease gene, but we may find disease genes on other
chromosomes that can be discovered in the same manner. We believe that our
ability to go from gene mapping to disease gene identification will be further
enhanced as the sequencing of the human genome is completed.

     Functional Genomics

     After we have succeeded in identifying a disease gene under our population
genomics approach, we will define molecular pathways in which the disease gene
plays a role. This is essential information both for understanding the biology
of the disease and also for identifying additional specific drug targets that
interact with the disease genes.

     We have established three complementary systems designed to isolate
specific drug targets from "upstream," "downstream" and "proximal" pathways that
may be involved in the disease process. We believe these three functional
approaches will expand the number of potential drug targets that are associated
with the specific disease genes identified using our population genomics
approach.

     Our proximal analysis uses a high-throughput yeast two-hybrid screening
system that can identify proteins that physically interact with the disease gene
product. As very few proteins work alone in the body, these partner proteins are
likely to be involved in the normal biology of the disease gene. We carry out
the screening in yeast cells, using methods of increasing stringency intended to
eliminate false positive protein-protein interactions. We have also developed
protein-interaction assays that can be used for membrane proteins that may be
difficult to analyze using two-hybrid technology. Complementing the two-hybrid
system with our membrane protein interaction assays is essential since
approximately 50% of known drug targets are membrane associated and may not have
been found using the two-hybrid system alone. We are also able to crossmatch the
genes identified as partners of the first disease gene with additional
population genomics data since they might be mutated in the same disease.

     Potential drug targets from upstream pathways include proteins that control
the expression level of the disease gene (i.e., those gene products that are
responsible for turning the disease gene on or off in particular tissues or
under particular conditions). We plan to link the control region of newly
identified disease genes to a "reporter" gene and establish precisely which
region governs expression. DNA from this region will be used to retrieve
specific binding proteins that are responsible for turning the disease on.
Finally, we plan to use gene expression analysis using Affymetrix GeneChip
technology to validate our conclusions and to identify other genes which are
regulated in tandem with the disease gene.

     Our downstream analysis is designed to uncover genes that are influenced by
the overexpression, underexpression or misexpression of the disease gene. We
have established efficient systems to turn a gene on or off in cells, as well as
to express mutated versions revealed in the course of gene discovery. We employ
DNA chip technology in our efforts to find genes whose expression patterns are
altered by different scenarios of disease gene expression. Some of these genes
may play a role together with the disease gene product in disrupting the normal
biology and leading to disease.

     DATABASE SERVICES

     The main focus of our database services will be first on the development
and then on the operation of the DCDP.

     Description of the DCDP

     We believe that the DCDP will represent the first opportunity in the world
to cross-reference genetic, phenotypic and genealogic data on a large scale. It
will provide a comprehensive opportunity to assign function to
                                       39
<PAGE>   41

genomic sequence. It will be designed to enable users to pose specific queries
to it through a software program, or query layer, which will process the
request. With these tools, users are expected to be able to query the various
data sets cross-referenced by the DCDP. The users' interactions will be confined
to the query layer; users will not have direct access to the data accessed by
the DCDP.

     We believe that the DCDP will permit users to build more complete models of
the interplay of genes, environment and disease than are currently available
primarily as a result of the following:

     -  the healthcare data contained in the IHD will include not only basic
        disease diagnosis but also details of laboratory results, treatments and
        outcomes;

     -  the IHD will contain a population rather than the handpicked patient
        lists used in existing approaches; and

     -  the IHD will contain medical information collected over time.

     There are three sources of data for the DCDP, which are as follows:

     Data from the Icelandic Healthcare System.  Under the terms of the IHD
license we will be able to process medical information, environmental exposure
information and resource use information from the Icelandic healthcare system.
The key data sources include:

     -  hospitals and ambulatory services;

     -  primary healthcare centers;

     -  private specialty clinics; and

     -  hospital and private laboratory results.

     A computerized network of medical records will be organized in each
participating healthcare institution. Information processed in the IHD will take
place in a manner designed to ensure that personal data remains non-personally
identifiable. The type of healthcare data will include admission data,
diagnostic work-up and results, diagnoses, treatment and operations for each
patient visit, medical and social history, allergies, risk factor exposure,
pharmaceutical treatment and outcomes.

     Genealogy Data.  The DCDP will access the same genealogy data that we use
in our current discovery services.

     Genotypic Data.  We plan to derive genotypes of consenting Icelanders who
give us blood samples in accordance with applicable regulations and consent to
have their genotypic data stored and cross-referenced with the IHD.

     Our genealogy database is complete for our applications. We are in the
early stages of development of the other two sources of data.

     The License

     On December 17, 1998, the Icelandic parliament passed the Act, allowing the
Ministry to grant an operating license to create and run the IHD. On January 22,
2000, the IHD license was granted to Islensk erfethagreining ehf., our
wholly-owned Icelandic subsidiary. The license, which has a term of twelve
years, allows us to collect data from medical records of Icelandic healthcare
institutions and self-employed health professionals, and to transfer such data
in encrypted form into a centralized database containing non-personally
identifiable information. It also permits us to cross-reference the IHD data
with genealogical data and genotypic data obtained through consent.

     Pursuant to the terms of the IHD license and the Act, before we can begin
collecting information and transferring it into the IHD, we must fulfill
numerous conditions, such as paying fees and costs associated with the license
and obtaining government approval of our privacy protection measures, and must
enter into agreements with healthcare institutions and self-employed health
professionals allowing us access to their medical records. Some medical
professionals, including the board of directors of the Icelandic Medical
                                       40
<PAGE>   42

Association, or IMA, have opposed the proposals for the establishment of the IHD
on ethical and privacy grounds. We do not believe that these views are
representative of the Icelandic medical profession as a whole or that they will
materially affect our ability to enter into such agreements. Once we have
entered into the required agreements, an independent security expert must verify
that our information systems and operating procedures comply with the data
security requirements of the Icelandic Data Protection Commission before we can
process the data we obtain from these healthcare providers.

     In addition to the scrutiny of the Data Protection Commission, our security
system for the IHD will benefit from the advice and monitoring of deCODE's
Security Advisory Board of internationally renowned experts in the fields of
computer security, data and privacy protection and security of healthcare
informatics. We expect this board of experts to meet periodically to review any
security issues we may encounter in our operations and in the development and
operation of the IHD and to provide us with technical advice for solving such
issues and maintaining or exceeding international best industry-practice
standards. We expect the Security Advisory Board to be appointed and operational
by May 2000.

     HEALTHCARE INFORMATICS

     Physicians are routinely required to cross-reference specific details
regarding their individual patients with their general knowledge of best medical
practice in clinics and hospitals. One of the main challenges facing physicians
today is how to deal with the vast and growing amount of medical knowledge. In
addition, the number of medical tests ordered and drugs that patients take are
leading to more information stored per patient. Some hospitals and clinics have
begun to use information technology to help store patient records. However, the
actual analysis and decision-making about diagnosis and treatment is still
mostly carried out by the un-aided human mind of the physician combining general
medical knowledge with specific patient data.

     While this approach has worked well in the past, it is an increasingly
difficult task which sometimes leads to delays in diagnosis and medical
mistakes. The complexity of physicians' decision-making may increase in the
future if genetics is integrated with the delivery of healthcare in the form of
predictive testing and treatments tailor-made to individual patients.

     deCODE believes that the "information load" on physicians will continue to
grow as the genetic dimension of healthcare leads to risk prediction and a shift
from generalized treatment guidelines to personalized care. This trend toward
personalized healthcare presents the following three opportunities in healthcare
informatics:

     -  We will use what is learned from our discovery programs and the DCDP to
       provide MDSS necessary to deliver and interpret this increased volume of
       data to a variety of end-users.

     -  We will use our experience in privacy protection in the DCDP to meet the
       increased need for privacy solutions that will accompany the increased
       volume of personally sensitive healthcare information.

     -  We will use our expertise in the gene and drug target discovery unit to
       develop and market bioinformatics tools.

     We also plan to pursue market opportunities for other software tools that
we have developed during the design and construction of the IHD and DCDP and in
our disease gene discovery efforts, including GeneMiner, DecodeGT and a
comprehensive sample database.

OUR STRATEGY

     deCODE's strategy is to use its population-based approach to transform
genomic and healthcare data into products and services for the healthcare
sector. The key elements of our strategy are as follows:

     Gene and Drug Target Discovery.  deCODE plans to pursue gene and drug
target discovery and the characterization of genes that contribute to the causes
of common diseases. In addition, we will use studies of gene expression and
protein-protein interaction systems to define molecular pathways, which may
contain drug targets. We will focus on diseases that have the potential to
result in the discovery of new proteins and drug candidates. We will also seek
to identify disease genes for the purpose of developing diagnostic products.

                                       41
<PAGE>   43

     Database Subscription and Consulting Services.  deCODE expects to build and
operate the DCDP, which is intended to process and cross-reference
non-personally identifiable healthcare information on the Icelandic population
(in the IHD) with genealogy data and genetic data obtained through consent. In
addition, we are developing new mathematical algorithms to extract further
knowledge from the DCDP. Services we plan to offer to future subscribers of the
DCDP will include principally gene discovery and drug target validation,
pharmacogenomics, disease management and health management. Subscribers are
expected to include pharmaceutical companies, healthcare organizations, national
health services and government agencies that will pay subscription fees and, in
some cases, a share of product revenues they generate as a result of using the
database.

     Pharmacogenomics Partnerships.  In collaboration with pharmaceutical
companies, we intend to apply pharmacogenomics to understand differences in drug
response among individuals. We believe that genomics will permit the
identification of the genetic differences that cause different people to respond
differently to the same drugs and that, as a result, it will be possible to
individualize the selection of drugs for patients. We believe that the
integration of medical treatment and outcome information with genetic
information will give us an advantage in the generation of pharmacogenomics
information. We expect to generate revenues from these partnerships through
fixed research funding and milestone and royalty payments.

     Sale and Marketing of Healthcare Informatics Products.  We plan to exploit
market opportunities for software tools that we develop during the design and
construction of the IHD and DCDP and in our disease gene discovery efforts. The
software tools that we have already developed include GeneMiner, DecodeGT, an
encryption system, and a comprehensive sample database. We expect to offer
healthcare informatics services, such as MDSS and privacy solutions. The
decision-support tools would, for example, be useful in areas such as medical
record keeping and its standardization and in medical decision making. deCODE
may provide specialized services to customers such as governmental agencies and
medical institutions which will enable them to collect and process information
in a standardized form. We intend to capitalize on our experience in the
protection of privacy of medical and genetic data to market systems for the
protection of privacy in healthcare. The customers for these services could
include industry, public institutions and governments.

     Formation of Collaborations.  We intend to seek corporate collaborations or
joint ventures with pharmaceutical and biotechnology companies to provide
research alliances, product development and commercialization for our gene and
drug target discovery programs. We expect to generate revenues from these
collaborations through research funding and milestone and royalty payments. We
also plan to seek collaborators for the development and marketing of our
database and healthcare informatics products and services.

PRODUCTS AND SERVICES

     Our current services and those under development can be classified into
three categories, all of which are based on analyzing data from the Icelandic
population using our proprietary bioinformatics tools: discovery services;
database services; and healthcare informatics.

     DISCOVERY SERVICES

     Current Discovery Programs

     We have started gene discovery programs associated with 27 common diseases,
12 of which are collaborative programs with Roche. The inheritance patterns of
many common diseases are complex, indicating that the diseases are probably
caused by mutations in one or more genes and/or through interactions between
genes and environment. We believe that these diseases represent large market
opportunities for therapeutic and diagnostic products because:

     -  their causes are not fully understood;

     -  current treatments are of limited effectiveness;

     -  there are currently no approaches to tailor treatment to cause; and

     -  large numbers of individuals are affected by these diseases.
                                       42
<PAGE>   44

     The identification of disease genes is expected to provide insights into
the causes of common diseases and to help the development of highly-specific
diagnostic and therapeutic products, including small molecule products,
recombinant proteins, gene therapy and antisense therapy. The following table
sets forth the current status of our gene discovery programs.

     The following is a description of the diseases in which our programs are
most advanced.

     Autoimmune Diseases.  We are currently studying several autoimmune diseases
such as inflammatory bowel disease (Crohn's and ulcerative colitis), psoriasis,
atopy and rheumatoid arthritis. All four are in large genome-wide linkage scans,
and we have found the location of a novel psoriasis gene.

     -  Psoriasis.  Psoriasis is a chronic inflammatory disease that leads to
        disfiguring skin lesions and arthritis. We have completed a genome-wide
        linkage scan of Icelandic familial material and have confirmed linkage
        and association to a region of the genome that regulates immune response
        known as the MHC. Our genome-wide scan also identified a novel region of
        the genome that interacts with the MHC to cause psoriasis. Our second
        location represents the second gene mapped outside the MHC that fulfills
        the criteria for genome-wide significance. We are in the process of
        fine-mapping both gene locations.

     Cardiopulmonary Diseases.  We are studying a variety of common diseases
such as asthma, chronic obstructive pulmonary disease, myocardial infarction,
peripheral vascular disease and stroke. We have already achieved a milestone
with Roche for finding the location of a gene associated with stroke.

     -  Cerebrovascular disease (Stroke).  Stroke represents diseases that
        directly or indirectly affect the blood vessels in the brain and cause
        central nervous system damage from either blockage of cerebral blood
        flow or rupture of an intracranial artery. It is the third leading cause
        of death. We have formed a research alliance with local physicians who
        care for a majority of the stroke patients diagnosed in Iceland. We have
        collected almost 2,000 DNA samples from informative families and
        genotyped most of them. Using our genealogical approach, we have mapped
        the location of one stroke gene that meets the criteria for genome-wide
        significance. This represents the first gene ever mapped for the common
        forms of stroke.

     Central Nervous System Diseases.  We are studying the genetic basis for
psychiatric and central nervous system diseases. We have achieved two milestones
in our collaboration with Roche by mapping the location of genes contributing to
the following diseases.

     -  Alzheimer's Disease.  Alzheimer's disease is the most common cause of
        dementia. We have carried out a genome-wide scan that included 1,200
        Icelanders. We have mapped late onset Alzheimer's disease to a novel
        chromosome location. We are currently fine-mapping the gene location.

     -  Schizophrenia.  Schizophrenia is a debilitating psychiatric disorder. No
        group has ever reported the isolation of a schizophrenia gene. We and
        our clinical collaborators have collected a significant number of DNA
        samples from the largest families in Iceland. We have carried out a
        genome-wide scan, and we are currently fine-mapping and sequencing one
        small region of the genome. We have also identified three candidate
        disease genes.

     Metabolic and Other Diseases.  We are studying the genetic basis for
osteoarthritis, non-insulin-dependent diabetes, osteoporosis and endometriosis.
We have achieved a research milestone in our collaboration with Roche for
mapping a gene associated with osteoarthritis.

     -  Osteoarthritis.  Osteoarthritis is a degenerative disease of the joints.
        There are currently no known genes causing the common forms of
        osteoarthritis. We have mapped three genes linked to osteoarthritis. We
        are currently fine-mapping and sequencing these regions to search for
        the disease genes themselves.

     Collaborations

     Our strategy for pursuing business opportunities is to establish alliances
with pharmaceutical companies, biotechnology firms and other healthcare
institutions to perform research into the genetic basis of a given disease or
group of diseases. Depending on the nature of each prospective business
opportunity, we may conduct the research in return for one or more of the
following: up-front equity investments; direct payments for research funding;
payments upon the achievement of scientific milestones; shared or exclusive
rights to diagnostics and therapeutics; and royalties on products marketed by
our collaborators. In some instances, we may negotiate for access to our
collaborators technologies, including libraries of chemical compounds, to
enhance our operations outside of the collaboration.

                                       44

     Hoffmann-La Roche.  In February 1998, we entered into a research
collaboration and cross-license agreement with Roche to collaborate on the
discovery of genetic variations which affect the cause of diseases for the
purpose of developing new methods to diagnose diseases and obtain drug targets
useful in drug discovery. The agreement provides for a steering committee, the
membership of which is equally divided between the parties, to oversee the
collaborative research programs. Under the terms of the agreement, Roche is
funding the collaborative gene discovery programs in twelve diseases, including
four cardiovascular diseases, four psychiatric/neurologic diseases and four
metabolic diseases, by making specified payments according to a payment
schedule. Roche's obligation under the agreement to fund these programs will
continue until February 1, 2003 provided that Roche elects to extend the
research term of the agreement for the one-year periods commencing on the third
and fourth anniversaries of the agreement. In addition to research funding
payments, we are entitled to receive payments from Roche upon the achievement of
specified scientific development and marketing milestones. We have reached four
milestones in this collaboration.

     The agreement gives Roche exclusive worldwide rights to develop and
commercialize therapeutic and diagnostic products based on gene discoveries.
Roche is required to pay us royalties on sales of any such products. We retained
the exclusive, worldwide rights to develop and commercialize gene therapy and
antisense products based on our gene discoveries and will be required to pay
Roche royalties on sales of any such products.

     In connection with the agreement, Roche Finance Ltd, or Roche Finance, an
affiliate of Roche, has purchased shares of our Series C preferred stock and has
an option to purchase additional shares at any time prior to the end of February
2001. Roche Finance has also purchased warrants to buy shares of our Series C
preferred stock and will be entitled to purchase additional warrants if it
exercises its option to acquire additional shares of Series C preferred stock.
These will become warrants to purchase an equivalent amount of common stock upon
the completion of this offering.

     Pursuant to an agreement, we license our GeneMiner bioinformatic software
product to Roche.

     In addition to the research collaboration with Roche, we have entered into
the following collaborations:

     Affymetrix Inc.  In November 1998, we entered into a DNA array internal use
license agreement. Under the non-exclusive agreement, Affymetrix has licensed
its DNA array technology to us for use in our gene expression experiments and
for purposes of exploring the technology's genotyping capabilities. Access to
Affymetrix's technology, coupled with our unique population based approach, now
provides us with a powerful solution for performing and analyzing array-based
gene expression experiments. The use of this technology is consistent with our
objectives to augment our existing technology portfolio to include alternative
gene discovery and gene functionality tools. It will also help us to explore the
options of array-based genotyping approaches using SNPs.

     License from The Beth Israel Deaconess Medical Center.  We have obtained an
exclusive license from The Beth Israel Deaconess Medical Center, or Beth Israel,
in Boston, Massachusetts to develop and commercialize therapeutic and diagnostic
products anywhere in the world based on Beth Israel's interest in patents and
know-how relating to the linkage between a particular segment of DNA and
multiple sclerosis. Under the terms of the agreement, we are obligated to pay
license fees and other payments upon the achievement of specified milestones. We
are also obligated to pay royalties to Beth Israel on the sales of products that
may result from the licensed technology.

     Hospital and Physician Collaborations.  We have entered into collaboration
agreements and arrangements with the three largest hospitals in Iceland, the
Icelandic Heart Association and with several physician groups pursuant to which
the hospitals and physicians will help to construct lists of patients with
specific diseases and provide expertise and clinical and research data related
to our research projects. Under these arrangements, we will reimburse expenses.
In addition if we sell the results of a project to a third party, we will make
specified upfront payments and will pay a portion of any performance-based
milestones and royalties we receive from these third parties. Payments generally
go into specially designated funds for further research.

     Pharmacogenomics

     Through its access to relevant data (e.g., through the cross-referencing of
genetic and phenotypic information), deCODE plans to offer pharmacogenomic
services to pharmaceutical and biotechnology
                                       45

companies. In this way, we believe that we will be able to assist pharmaceutical
companies in tailoring drugs to specific parts of the patient population.
Tailor-made drugs will better ensure both effectiveness and safety. In addition,
it is expected that genetic information may lead to faster and more successful
clinical trials, which may result in cost savings. Pharmacogenomics may also
enable pharmaceutical companies to explore the use of older chemical compounds
which have been abandoned. Because the development cost of these compounds has
already been incurred, the additional cost to bring these products to market may
be reduced.

     Internal Programs

     We also plan to work on some diseases without partnering with
pharmaceutical companies, and we are currently pursuing a number of disease
projects independent of research sponsorships. In the event we complete any
independent projects, we intend to pursue the commercial development of our gene
and drug target discovery through the development and marketing of therapeutics
and diagnostic products. We may do this by using our own resources to turn
discoveries from our internal projects into therapeutic or diagnostic products
and developing our own marketing capabilities, by licensing our discoveries to
others who would be required to pay us royalties on sales of any products they
develop using the results of our gene discovery programs or by entering into
collaborative arrangements for the development and marketing of products from
these programs.

     DATABASE SERVICES

     The DCDP is intended to allow users to ask questions about relationships
between genetic and environmental data and disease. We believe the DCDP should
increase the utility of human genome sequence data by providing a medical and
environmental context, which should facilitate the development of new products
and services for healthcare.

     Products

     Gene Discovery and Drug Target Validation.  We expect the DCDP to be used
in gene discovery programs and drug target validation by pharmaceutical and
biotechnology companies as a way of confirming their own provisional findings or
providing an impetus for further research. We expect that the DCDP will be used
to search the human genome for gene mutations that are linked to the occurrence
of a particular disease.

     Pharmacogenomics.  We expect the DCDP to improve understanding of how drug
response can vary across a population due to underlying genetic differences. For
example, a customer might search for a region of the genome that appears to be
shared by patients with similar drug responses. Pharmacogenomic analysis with
the DCDP is therefore an opportunity for pharmaceutical companies to market
products which more closely meet the needs of a diverse market.

     Disease Management.  The DCDP is uniquely positioned to provide new
insights and help design disease management programs. By carefully analyzing
clinical data and correlating such data with genetic factors, healthcare
providers may develop programs that cover the lifespan of the disease, from
preventive actions to determining the most appropriate treatments for each
individual. For a healthcare provider, which is constantly making the
cost/quality tradeoff, this is a unique way to design programs which optimize
both cost and quality.

     Health Economics.  We believe that a major trend in healthcare is the shift
from managing disease towards maintaining individual health. Providers are under
pressure to stop focusing on therapeutic areas in isolation and to begin
considering an individual's risk of disease in general. In order to do this,
providers will need to understand inter-relationships between different
therapeutic areas and health indicators so that they can analyze the costs and
benefits of various treatments or behavioral modifications. We believe that the
DCDP will naturally lend itself to this kind of analysis by processing data
across the major therapeutic areas as well as information on well-being and
lifestyle. For example, a customer may use the DCDP to analyze a particular
preventive measure known to reduce the risk of a target disease to see if that
measure may increase the patient's risk of developing other diseases.

                                       46

     Customers

     We believe that the potential customer base for the DCDP consists of
members of the healthcare industry, including:

     -  Pharmaceutical and Biotechnology Companies.  The DCDP may be used by
        pharmaceutical and biotechnology companies in their gene discovery and
        pharmacogenomics programs.

     -  Health Organizations.  Healthcare providers, including health
        maintenance organizations, managed care groups and hospital groups may
        use the DCDP to help them determine the most appropriate method of care
        for patients.

     -  National Health Services and Government Agencies.  National health
        services and government agencies may use the database to save money by
        determining the most effective allocation of resources.

     We anticipate that our customers will pay for access to the database by
means of a fixed subscription plus, in the case of pharmaceutical and
biotechnology companies, a share of any product revenues they generate as a
result of using the database.

     Collaborations

     During our development of the DCDP, we intend to establish alliances with
partners who can contribute to the creation of the DCDP and IHD and complement
our efforts. Potential areas of collaboration include access to comparable data
from populations outside Iceland, assistance from potential users with the
design of products and technical expertise from vendors or consultants. We
anticipate that any partner would contribute to funding of the development of
the DCDP.

     HEALTHCARE INFORMATICS

     We have identified three product opportunities in healthcare informatics to
leverage capabilities derived from our gene discovery and database operations.

     Products

     Bioinformatics.  To aid in our gene and drug target discovery work, we have
developed numerous proprietary bioinformatics tools for genealogy analysis,
project management, gene mapping, physical mapping, and gene identification
which we hope to commercialize as independent products.

     A description of these tools is illustrated below:

<TABLE>
<CAPTION>
TYPE                            DESCRIPTION
- ----                            -----------
<S>                             <C>
Genealogy tools:                -  Clustering algorithms are used to compare lists of
                                patients with the genealogy database to determine relevant
                                   patient relationships.
                                -  Special datamining algorithms are used to determine the
                                genetic component of traits.
Project management tools:       -  Our sample manager is used to track blood and DNA samples
                                that have arrived in the laboratory, throughout the
                                   discovery process.
                                -  Our project manager is used to keep track of all patient
                                blood samples, DNA samples, pedigrees, and medical
                                   information in research projects.
Genotyping tools:               -  Our genotype viewer automates the fractionation of data
                                according to quality, decreasing the amount of labor.
                                -  The marker manager manages large genetic marker sets
                                collated in the laboratory and is used to view and define
                                   maps for statistical analysis.
                                -  Our genotype manager manages the imports and exports of
                                the genotypes for a given set of patients and markers.

                                -  The Observer is a quality control tool for genotyping and
                                sequencing facilities.
Statistical tools:              -  The Allegro linkage analysis program has computational
                                power which is one to two orders of magnitude more efficient
                                   than previously developed statistical analysis programs
                                   known in the public domain.
Physical mapping tools:         -  Our software automates the process of reading physical
                                mapping hybridization data through image analysis and uses
                                   data-mining tools that combine multiple data sources.
Gene discovery tools:           -  GeneMiner is used to discover new genes through the use
                                of sequence information alone; it analyzes up to a million
                                   base pairs of sequence; its graphical interface allows
                                   user annotation; and it permits integration of third
                                   party information (exon and gene predictors, sequence
                                   comparison programs, mouse and human homology comparisons
                                   and repeat similarity)
</TABLE>

     Privacy Protection.  deCODE has developed expertise in encryption
mechanisms and security management to fulfill the Icelandic Data Protection
Commission's requirements. For example, our encryption tools provide for privacy
of blood samples that enter our laboratory. We believe that the opportunity to
commercialize this expertise will grow as the healthcare industry seeks to take
advantage of the benefits offered by information technology to manage complex
healthcare data while maintaining patient confidentiality.

     Medical Decision-Support Software.  In deciding how to treat patients,
physicians are routinely required to make the appropriate link between the
specific details regarding patients and their general knowledge of best medical
practice. One of the main challenges facing physicians today is how to deal with
the vast and growing amount of information about best medical practice and the
specific circumstances of their patients. Medical decision-support software
provide computer-based assistance to physicians in assimilating and using
available information. deCODE expects to offer products which will include ways
of combining medical knowledge with patient information such as symptoms and
test results to assist physicians in determining diagnosis and treatment while
addressing patients' concerns about the confidentiality of their personal
medical data.

     Customers

     Bioinformatics.  We believe that the customers for our bioinformatics tools
will mainly consist of pharmaceutical and biotechnology companies. However, we
also expect to attract customers in other areas of the healthcare industry.
These customers will use our tools to aid in their gene and drug target
discovery programs.

     Privacy Products.  We believe that privacy products can potentially be sold
to any company handling sensitive data about individual persons, whether or not
the data are healthcare-related. However, pharmaceutical companies, healthcare
providers and payors with substantial quantities of individual data protected by
privacy restrictions will serve as our primary target. One such opportunity is
to develop a secure Internet environment for government agencies collecting
nation-wide patient data from mobile field staff. Other opportunities relate to
developing and supporting medical decision-support services and enabling secure
remote access by patients, physicians and other users or to a distributed
network.

     Medical Decision-Support Software.  Products and services in the field of
decision support have a broad potential customer base in the healthcare
industry. deCODE's initial focus will be on healthcare providers, government
agencies, physicians and HMOs, all of whom use support tools that capture and
analyze patient data to assist them in healthcare decision-making.

RESEARCH AND DEVELOPMENT EXPENSES

     Our research and development expenses were $31,823,950 in 1999, $19,282,364
in 1998 and $6,080,096 in 1997. Of these amounts, we estimate that $21,003,807
in 1999, $12,726,360 in 1998 and $0 in 1997 were customer sponsored research
activities.

                                       48
<PAGE>   50

PATENTS AND PROPRIETARY RIGHTS

     We will be able to protect our proprietary rights from unauthorized use by
third parties only to the extent that our proprietary rights are covered by
valid and enforceable patents or are effectively maintained as trade secrets.
Accordingly, patents and other proprietary rights protections are an essential
element of our business. We currently rely on patents, trade secret law and
contractual non-disclosure and confidentiality arrangements to protect our
proprietary information. We intend to seek patent protection in the United
States and other jurisdictions to protect technology, inventions and
improvements to inventions that are commercially important to the development of
our business, including genes we discover, mutations of genes and related
processes and inventions, technologies which may be used to discover and
characterize genes, and therapeutic and diagnostic processes and other
inventions based on these genes. We have no issued patents but have filed eleven
patent applications in the United States. We also intend to seek patent
protection or rely upon trade secret rights to protect other technologies that
may be used to develop databases and healthcare informatics products and
services.

COMPETITION

     We face, and will continue to face, intense competition in our gene
discovery programs from organizations such as major pharmaceutical companies,
specialized biotechnology firms, universities and other research institutions,
the Human Genome Project and other government-sponsored entities. A number of
entities are attempting to rapidly identify and patent genes responsible for
causing diseases or an increased susceptibility to diseases and to develop
products based on these discoveries.

     Competition is also intense in the healthcare informatics and database
areas. Many companies are focusing on medical record systems and cost-oriented
patient databases as well databases containing genomics information.

     Many of our competitors, either alone or together with their collaborative
partners, have substantially greater financial resources and larger research and
development staffs than we do. These competitors may discover, characterize or
develop important genes, drug targets or drug leads before we or our
collaborators do or may obtain regulatory approvals of their drugs more rapidly
than we or our collaborators do. They may develop healthcare informatics and
database products before we do or which are technically superior to ours or
prove to be more useful to our potential customers.

     Developments by others may render pharmaceutical product candidates or
technologies developed by us or our collaborators obsolete or non-competitive.
Any product candidate that we or our collaborators successfully develop may
compete with existing therapies that have long histories of safe and effective
use.

     Our competitors may obtain patent protection or other intellectual property
rights that could limit our rights, or our customers' ability, to use our
technologies, healthcare informatics products or databases, or commercialize
therapeutic or diagnostics products. In addition, we face, and will continue to
face, intense competition from other companies for collaborative arrangements
with pharmaceutical and biotechnology companies, for establishing relationships
with academic and research institutions and for licenses to proprietary
technology.

     Our ability to compete successfully will depend, in part, on our ability,
and that of our collaborators, to:

     -  develop proprietary products;

     -  develop and maintain products that reach the market first, and are
        technologically superior to and more cost effective than other products
        on the market;

     -  obtain patent or other proprietary protection for our products and
        technologies;

     -  attract and retain scientific and product development personnel;

     -  obtain required regulatory approvals; and

     -  manufacture, market and sell products that we develop.

GOVERNMENT REGULATION

     Regulation by governmental authorities will be a significant factor in our
ongoing research and development activities and in our proposed business
relating to the DCDP. In addition, the development, production and marketing of
any pharmaceutical products which we or a partner may develop is subject to
regulation by governmental authorities.

     THE IHD LICENSE

     The DCDP and the IHD are subject to applicable Icelandic law. The IHD will
be developed and operated pursuant to an operating license from the Ministry and
will be subject to the Act, the regulations promulgated under the Act, the
license and an agreement between the licensee and the Ministry, all of which
impose numerous requirements on our activities.

     As required by the license, concurrently with the issuance of the license,
we, through our Icelandic subsidiary, entered into an agreement with the
Ministry. This agreement provides that we must pay the Icelandic government a
fixed annual fee of 70 million Icelandic kronas (approximately $1,000,000) and
an additional annual fee of 6% of its net profit, up to a maximum of 70 million
Icelandic kronas per year (approximately $1,000,000). The agreement also
provides that our rights to the IHD will be transferred to the Ministry on the
expiration or termination of the license.

     The license and the agreement under which we received the license also
require us to:

     -  pay the costs incurred by the health institutions (including the costs
        of medical record software) in connection with the entering of data from
        medical records before transfer to the IHD;

     -  financially segregate the operation of the IHD from our other activities
        by maintaining a separate operating unit and separate accounts for IHD
        operations;

     -  pay the costs of the governmental agencies which monitor our IHD
        activities;

     -  indemnify and agree not to sue the Icelandic government for any
        liability resulting from the passage of the legislation on the IHD and
        its operation and/or the issuance of the IHD; and

     -  observe international bioethics rules.

     The license prohibits us from, among other things:

     -  abusing our position by charging unreasonable fees, refusing business to
        our competitors or discriminating among customers by imposing
        discriminatory or other onerous business terms on our customers; or

     -  assigning or pledging our rights in the license.

     The Act places a number of duties on us, as the IHD licensee, and imposes a
number of conditions on the IHD license. Under the Act, we are prohibited from
allowing direct access to the IHD and must keep the IHD and processing of the
database in Iceland. Our employees and contractors must sign an irrevocable
confidentiality oath prior to commencing employment or performing services on
our behalf. At the expiration of the IHD license, we are required to ensure that
the Ministry or a party entrusted by the Ministry will receive, without payment
of consideration, intellectual property rights necessary for the creation and
operation of the database for public health purposes and for scientific
research.

     The IHD license may be revoked if we or our employees violate the terms of
the Act, if the conditions of the license are not fulfilled, or if we become
unable to operate the IHD. If we or our employees or any person assigned to
process data violate the provisions of the Act or applicable regulations with
regard to confidentiality, we will be required to compensate any persons to whom
the data relate for financial loss which the violation causes. If results
obtained from cross-referencing data in the DCDP prove to be personally
identifiable, the Data Protection Commission may, among other actions, order the
destruction of such results in their entirety or in part or revoke its approval
of the procedures and work processes applied by us to ensure privacy of the IHD
data.

                                       50
<PAGE>   52

     The IHD license will be reviewed by the Ministry no later than October 1,
2008. During the course of the review, we and the Ministry will enter into
discussions for the renewal of the license after its expiration in 2012 provided
that deCODE continues to meet the requirements of all applicable laws and
regulations. The Ministry may also review the IHD license from time to time
following our request, on its own initiative or if the IHD license contravenes
any applicable laws or regulations.

     Our creation and operation of the IHD and the DCDP will involve oversight
by the Ministry, with the assistance of an IHD Monitoring Committee, an
Interdisciplinary Ethics Committee, the Bioethics Committee of Iceland and the
Data Protection Commission of Iceland. These bodies will help to ensure our
compliance with applicable laws and regulations.

     The Monitoring Committee consists of three members who are appointed by the
Minister of Health and Social Security. The Monitoring Committee will ensure
that the licensee complies with the Act and applicable regulations by monitoring
negotiations and agreements for the transfer of data and reporting any events of
noncompliance with the Act to the Ministry. The Monitoring Committee is charged
with protecting the interests of the public health authorities, health
institutions, self-employed health service workers and scientists in the process
of making agreements between us and those parties.

     The Interdisciplinary Ethics Committee will review query types and monitor
research projects for compliance with internationally accepted ethical standards
for scientific research involving human beings. Members of the Interdisciplinary
Ethics Committee are appointed by the Ministry and may halt any query or
research project deemed by the committee to violate such standards.

     The Bioethics Committee of Iceland is a standing committee appointed by the
Ministry that oversees scientific research relating to human beings in Iceland.
It has no direct supervisory function over our IHD license but will provide
ethical advice to the Monitoring Committee based upon quarterly reports
containing lists of queries and patient data submitted to the IHD.

     Members of the Data Protection Commission, which is a standing committee
responsible for overseeing rights of privacy and data protection in Iceland, are
appointed by the Minister of Justice and include health, legal and computer
specialists. The Data Protection Commission establishes the technology, security
and organizational terms with which we must comply in the development of the IHD
pursuant to the IHD license. The Data Protection Commission may periodically
review such terms in light of new technologies, experience or change of
circumstances, and we will be required to comply with the revised data
protection terms within the deadline established by the Data Protection
Commission. The Data Protection Commission will monitor the security of the
collection, use and access to patients' information and may intervene to prevent
breaches of such security. The Data Protection Commission will ensure that we
comply with the privacy laws applicable in Iceland and will administer the
access limitations to data and encryption methodology used for the IHD.

     PHARMACEUTICAL PRODUCTS

     Our success will depend, in part, on the development and marketing of
products based on our research and development. Our ability and our partners'
ability to successfully manufacture and market therapeutic or diagnostic
products will be subject to strict regulatory controls on the clinical testing,
manufacture, labelling, supply and marketing of the products. Most countries
require a company to obtain and maintain regulatory approval for a product from
the relevant regulatory authority to enable the product to be marketed.
Obtaining regulatory approval and complying with appropriate statutes and
regulations is time-consuming and requires the expenditure of substantial
resources.

     Most European countries and the United States have very high standards of
technical appraisal and consequently, in most cases, a lengthy approval process
for pharmaceutical products. The regulatory approval processes, which usually
include pre-clinical and clinical studies, as well as post-marketing
surveillance to establish a compound's safety and efficacy, can take many years
and require the expenditure of substantial resources. Data obtained from such
studies is susceptible to varying interpretations that could delay, limit or
prevent regulatory approval. Delays or rejections may also be encountered based
upon changes in drug approval

                                       51
<PAGE>   53

policies in applicable jurisdictions. There can be no assurance that we or our
collaborative customers will obtain regulatory approval for any drugs or
diagnostic products developed as the result of our gene discovery programs.

     Because many of the products which may result from our research and
development programs are likely to involve the application of new technologies,
such products may be subject to substantial additional review by various
governmental regulatory authorities. As a result, regulatory approvals may
require more time than for products using more conventional technologies. In
addition, ethical concerns about the use of genetic predisposition testing, and
in particular about the risk that such testing could lead to discrimination by
insurance providers or employers, may lead to poor market acceptance or to
regulatory controls that would adversely affect the development of or demand for
diagnostic products based on our research.

     ENVIRONMENTAL

     Our research facilities and laboratory are located in Reykjavik, Iceland.
We operate under applicable Icelandic and European Union laws and standards,
with which we believe that we comply, relating to environmental, hazardous
materials and other safety matters. Our research and manufacturing activities
involve the generation, use and disposal of hazardous materials and wastes,
including various chemicals and radioactive compounds. These activities are
subject to standards prescribed by Iceland and the EU.

EMPLOYEES

     As of December 31, 1999, we had approximately 310 employees, of whom
approximately 295 were employed full-time, 47 held Ph.D. or M.D. degrees and
approximately 171 held college degrees. 267 employees were engaged in, or
directly supported, research and development activities, of whom 185 worked
within the laboratory facilities and 50 held positions associated with the
development of informatics. 38 employees were engaged in business development,
finance, administration and facilities management. In addition, we utilized
part-time employees and outside contractors and consultants as needed and plan
to continue to do so. We anticipate hiring approximately 100 software developers
in 2000-2001.

     We have entered into individual employment contracts with our employees in
accordance with standard Icelandic hiring practices. We believe that the
relationship with our employees is good. Furthermore, to help protect our
proprietary know-how and data, each employee must agree not to disclose any
trade secret or confidential information without our prior consent. Employees
also assign to us all patent rights and technical information which they develop
during employment.

FACILITIES

     Our headquarters are located at Lynghals 1, Reykjavik, Iceland, a business
district. This three-story building, which we lease pursuant to a sale/leaseback
arrangement, has 3,300 square meters, or approximately 30,000 square feet, of
floor space including our laboratory space, executive offices, support and
administrative space. The lease expires in 2008, at which time the property will
be transferred to us, provided we have complied fully with the lease. We may
also build a 1,500 square meter, or approximately 13,500 square foot, facility
on adjacent land. In addition, we maintain a facility for approximately 15
genealogists located in Thornverholt 14, Reykjavik and we lease 533 square
meters, or approximately 5,000 square feet, of additional office space for our
database department at Hlietharsmari 19, Kopavogur, Iceland. We have also
entered into a lease for a 1,923 square meter, or approximately 19,000 square
foot, facility located at Hlietharsmari 15, Kopavogur, Iceland to conduct
database and informatics activities.

     On February 14, 2000, we entered into an agreement with the City of
Reykjavik and the University of Iceland pursuant to which, subject to municipal
approval, we will be entitled to enter into a lease and construct a 10,000
square meter, or approximately 108,000 square foot, facility to replace our
current headquarters facility. If such approval is granted, we expect to
complete the project within the next two years.

LEGAL PROCEEDINGS

     We are not a party to any material legal proceedings except for an action
commenced on January 13, 2000 in the District Court of Reykjavik in Iceland by
Thornorsteinn Jonsson and Genealogia Islandorum hf., the holders of copyrights
to approximately 100 books of genealogical information. They allege that our
genealogy database infringes their copyrights and seek damages in the amount of
approximately $9,000,000 and a declaratory judgment to prevent us from using the
allegedly infringing data. We believe the suit is without merit and intend to
defend this action vigorously.

believe they are entitled to shares of deCODE's common stock. deCODE believes
these assertions are without merit and intends to defend any actions which these
parties may commence.

EMPLOYMENT AGREEMENTS

receive offer letters specifying basic terms and conditions of their employment.
We have entered into employment agreements with Mr. Erlendsson and Mr. Bjornsson
that allow either party to terminate the agreement upon three months and six
months prior notice, respectively.

     Our executive officers have signed agreements which require them to
maintain the confidentiality of our information and to assign inventions to us.
These agreements also prohibit these officers from competing with us during the
terms of their employment and for two years thereafter by engaging in any
capacity in any business which is, or on the date of termination of their
employment was, competitive with our business.

                              CERTAIN TRANSACTIONS

     In January 1998 and August 1999, we granted to Hannes Smarason, our
Executive Vice President and Senior Business and Finance Officer, options to
purchase 300,000 and 260,000 shares of our common stock, respectively. In
November 1998, we granted to Sigurethur Bjornsson, our Vice President, Medical
Informatics, an option to purchase 120,000 shares of our common stock. Messrs.
Smarason and Bjornsson immediately exercised their options pursuant to the early
exercise right granted to all our employees. At the times of exercise, Mr.
Smarason delivered to us promissory notes in the principal amounts of $59,700
and $1,462,240 and Mr. Bjornsson delivered to us a promissory note in the amount
of $479,880. Each of these promissory notes bears interest in the amount of six
percent (6%) per annum. The notes are due and payable on January 1, 2001,
November 1, 2003 and February 1, 2003, respectively. The shares purchased by Mr.
Bjornsson and Mr. Smarason in 1998 vest at the rate of 1/4 on the first
anniversary of the date of employment and 1/48 on the last day of each month
thereafter. The shares purchased by Mr. Smarason in 1999 vest at the rate of
1/48 on the first day of each month, commencing December 1, 1999. As of December
31, 1999, the principal and accrued interest on the notes delivered by Mr.
Smarason in 1998 and 1999 was $66,769 and $1,487,432, respectively, and the
principal and accrued interest on the note delivered by Mr. Bjornsson was
$512,340.

     Kari Stefansson, our Chairman, Chief Executive Officer and President, and
Mr. Smarason are stockholders in an Icelandic company which has entered into a
research collaboration with deCODE for discovery of compounds made from
thermophilic organisms. We provide funding for, and own the rights to all
intellectual property created in, this collaboration. During 1998 and 1999 we
made research funding payments to the company in the aggregate amount of
$593,955.

     In February and May 1999, we sold to Roche Finance shares of Series C
preferred stock and warrants to purchase shares of Series C preferred stock for
an aggregate purchase price of $3,333,445.

     In August 1999, we

     -  repurchased 13,559 shares of Series A preferred stock held by Alta
        Embarcadero Partners, LLC, 507,711 shares of Series A preferred stock
        held by Alta California Partners, L.P., 260,635 shares of Series A
        preferred stock held by Atlas Venture Europe Fund, B.V., 260,635 shares
        of Series A preferred stock held by Atlas Venture Fund II, L.P., 146,628
        shares of Series A preferred stock held by Medical Science Partners, II,
        L.P., 395,714 shares of Series A preferred stock held by Polaris Venture
        Partners, L.P. and 23,040 shares of Series A preferred stock held by

     -  issued (and repurchased) 250,000 shares of Series B preferred stock to
        Kari Stefansson in exchange for 333,333 shares of common stock held by
        him; and

     -  repurchased 100,000 shares of Series C preferred stock held by Roche
        Finance.

     The initial purchase price we paid for the shares of Series A preferred
stock, Series B preferred stock and Series C preferred stock was $7.50 per
share. Pursuant to the agreement of the parties, this price was subject to later
upward adjustment to reflect possible adjustment in the price at which we sold
shares of Series B preferred stock to a third party in August 1999. In December
1999, the purchase price was adjusted to $13.95 per share with the additional
amounts paid in February 2000. Mr. Nohra, one of our directors, is a general
partner of Alta Partners, which provides investment advisory services to Alta
California Partners, L.P. and Alta Embarcadero Partners, LLC. Dr. Formela, one

     Holders of shares of common stock are entitled to one vote at all meetings
of stockholders for each share held by them. The common stock has no preemptive
rights or other rights to subscribe for additional shares, no conversion right
and no right of redemption. Subject to the rights and preferences of the holders
of any preferred stock, the holders of the common stock are entitled to receive
such dividends as, when and if declared by the Board of Directors out of funds
legally available therefor for that purpose. We have not paid dividends on the
common stock. The payment of dividends, if any, in the future with respect to
the common stock is within the discretion of the Board of Directors and will
depend on our earnings, capital requirements, financial condition and other
relevant factors. At present, our Board of Directors does not intend to declare
any dividend on the common stock in the foreseeable future.

PREFERRED STOCK

     Of our 32,641,926 authorized preferred shares, 11,041,926 shares are
designated as Series A preferred stock, 10,000,000 shares are designated as

stock (held by approximately 5,000 holders of record), and 3,511,111 shares of
Series C preferred stock (held by one holder of record) were outstanding. In
addition, as of December 31, 1999, there were outstanding warrants to purchase
1,137,814 shares of Series A preferred stock and warrants and options to
purchase 972,223 shares of Series C preferred stock. Upon the closing of this
offering, all outstanding shares of preferred stock will be converted into
22,969,544 shares of common stock. In addition, all outstanding warrants to
purchase shares of preferred stock will be converted into warrants and options
to purchase shares of common stock.

     Each share of our outstanding classes of preferred stock bears dividends at
the rate of 8% of the original purchase price per share, payable when declared
by the Board of Directors. To date the Board of Directors has not declared any
dividends on the preferred stock. Our certificate of incorporation provides that
the outstanding preferred stock will convert to common stock upon the closing of
this offering, at which time all undeclared dividends will be cancelled.

     With respect to the 7,016,666 shares of preferred stock not currently
designated as an existing series, our Board of Directors is authorized, except
as otherwise limited by Delaware law, without further action by the
stockholders:

     -  to issue shares of preferred stock in one or more series;

     -  to fix or alter the dividend rights, dividend rates, conversion rights,

        redemption price or prices, and liquidation preferences of any wholly
        unissued series of preferred stock;

     -  to designate the number of shares constituting, and the designation of,
        any series of preferred stock; and

     -  to increase or decrease the number of shares of a series subsequent to
        the issue of shares of that series, but not below the number of shares
        of that series then outstanding.

STOCK OPTIONS

     We established our 1996 Equity Incentive Plan, or the 1996 Plan, for the
purposes of attracting and retaining the best available personnel, to provide
additional incentive to our employees and consultants and to promote our
success. Our incentive plan provides for: (i) the grant of stock options to
employees and consultants; (ii) the grant of stock bonuses to employees,
directors and consultants; and (iii) the grant of rights to purchase restricted
stock, on such terms and conditions our Board of Directors or a board committee
determines. The powers of our Board of Directors or board committee, as the case
may be, include the determination of which employees and consultants are to
receive stock option grants, the exercise price, number of shares and the
vesting schedule of the grants.

     At the discretion of our Board of Directors or board committee, any options
granted may permit the early exercise of the options, in whole or in part, prior
to vesting. We retain the right, upon termination of the option holder's
employment or consulting arrangement, to repurchase the shares of common stock
acquired as a result of an early exercise that are unvested on the date of
termination, at the price per share paid by the option holder at the time of
exercise of the option. All of the options granted to employees to date have
provided for an early exercise right.

     The total number of shares of common stock authorized for issuance under
the 1996 Plan is 5,000,000. As of December 31, 1999, 1,041,000 shares of common
stock were eligible for issuance upon the exercise of options available to be
granted under the 1996 Plan.

REGISTRATION RIGHTS OF STOCKHOLDERS

     Pursuant to the terms of an investor rights agreement, the holders of
  --  shares of common stock (including   --  shares of common stock issuable
upon exercise of warrants) (the "Registrable Shares") will have the right to
require us to file a registration statement under the Securities Act covering
the registration of

                                       64
<PAGE>   66

their shares at any time after 180 days from the effective date of the
registration statement of which this prospectus is a part if the holders of 50%
of such shares demand registration and the number of shares to be registered has
an aggregate public offering price of at least $5,000,000. We are not required
to effect more than two registrations for the holders pursuant to these demand
registration rights.

     In addition, holders of   --  shares of common stock are entitled to
piggyback registration rights with respect to the registration of these shares
under the Securities Act. If we propose to register any shares of common stock
under the Securities Act either for our account or for the account of our other
security holders, the holders of shares having piggyback rights are entitled to
receive notice of the registration and are entitled, with some limitation, to
include their shares in the registration.

     Further, at any time after we become eligible to file a registration
statement on Form S-3, any holder or holders of the then outstanding Registrable
Shares may require us to file registration statements under the Securities Act
on Form S-3 with respect to their shares of common stock.

     The above described registration rights are subject to conditions and
limitations, including the right of the underwriters of an offering to limit the
number of shares of common stock which security holders may include in a
registration. Further, we may defer a registration for a period of 90 days if we
furnish to the holders requesting registration a certificate signed by the
chairman of the board stating that in the good faith judgment of the Board of
Directors it would be seriously detrimental to deCODE and our stockholders for
the requested registration to be effected at that time. We are generally
required to bear all of the expenses of all such registrations, including the
reasonable fees of a single counsel acting on behalf of all selling holders,
except underwriting discounts and selling commissions. Registration of any of
the shares of common stock held by security holders with registration rights
would result in such shares becoming freely tradable without restriction under
the Securities Act immediately upon effectiveness of such registration.

DELAWARE LAW AND CERTAIN CHARTER AND BY-LAW PROVISIONS

     We are subject to Section 203 of the Delaware General Corporation Law
("DGCL") which is an anti-takeover provision. In general, the statute prohibits
a publicly-held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years after the date of
the transaction in which the person became an interested stockholder unless the
business combination is approved in a prescribed manner. A "business
combination" includes a merger, asset sale or other transaction resulting in
financial benefit to the stockholder. An "interested stockholder" is a person
who, together with affiliates and associates, owns (or within three years prior,
did own) 15% or more of a corporation's voting stock.

     Certain provisions in our certificate of incorporation, in our bylaws and
under Delaware law could make it more difficult for other companies to acquire
us, even if doing so would benefit our stockholders. For example, our
certificate of incorporation and bylaws provide for the issuance of preferred
stock. The use of preferred stock may have the effect of delaying, deferring or
preventing a change in control. Further, use of the preferred stock may have an
adverse impact on the ability of our stockholders to participate, if applicable,
in a tender offer or exchange offer for the common stock, which would diminish
the value of the common stock.

     The DGCL authorizes a corporation in its certificate of incorporation to
limit the personal liability of its directors for violations of their fiduciary
duty of care. Accordingly, our certificate of incorporation states that a
director will not be personally liable to deCODE or to our stockholders for
monetary damages resulting from any breach of fiduciary duty as a director,
except for the breach of the director's duty of loyalty to us or our
stockholders, acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, or a transaction from which the
director derives an improper personal benefit. The DGCL also authorizes a
corporation to indemnify its directors and officers, and our bylaws require that
we indemnify each director and executive officer to the fullest extent allowable
under the DGCL. We believe that these provisions will assist us in attracting
and retaining qualified individuals to serve as directors.

                           CERTAIN TAX CONSIDERATIONS

CERTAIN U.S. FEDERAL TAX CONSIDERATIONS FOR NON-U.S. HOLDERS OF COMMON STOCK

     The following is a general discussion of material U.S. federal income tax
consequences relating to the ownership and disposition of shares of common stock
by a beneficial owner thereof that is a non-U.S. holder. A non-U.S. holder is a
person or entity that, for U.S. federal income tax purposes, is a non-resident
alien individual, a foreign corporation, a foreign partnership, or other foreign
entity, or a foreign estate or trust.

     This discussion is based on the Internal Revenue Code of 1986, as amended,
or the Code, and administrative interpretations as of the date hereof, all of
which are subject to change, including changes with retroactive effect. This
discussion does not address all aspects of U.S. federal income taxation that may
be relevant to non-U.S. holders in light of their particular circumstances. In
particular, this discussion does not address non-U.S. holders who are subject to
U.S. federal income tax on their worldwide income or whose shares of common
stock are effectively connected with the conduct of a U.S. trade or business. In
addition, this discussion does not address any tax consequences arising under
the laws of any state, local or foreign jurisdiction. Prospective holders should
consult their tax advisors with respect to the particular tax consequences to
them of owning and disposing of shares of common stock, including the
consequences under the laws of any state, local or foreign jurisdiction.

     DIVIDENDS

     Subject to the discussion below, dividends paid to a non-U.S. holder of
common stock generally will be subject to withholding tax at a 30% rate or such
lower rate as may be specified by an applicable income tax treaty. For purposes
of determining whether tax is to be withheld at a 30% rate or at a reduced rate
as specified by an income tax treaty, we ordinarily will presume that dividends
paid on or before December 31, 2000, to an address in a foreign country are paid
to a resident of such country absent knowledge that such presumption is not
warranted.

     Under new United States Treasury Regulations applicable to dividends paid
after December 31, 2000, to obtain a reduced rate of withholding under a treaty,
a non-U.S. holder will generally be required to provide to us certification of
such non-U.S. holder's entitlement to benefits under a treaty. The new
regulations also provide special rules to determine whether, for purposes of
determining the applicability of a tax treaty, dividends paid to a non-U.S.
holder that is an entity should be treated as paid to the entity or those
holding an interest in that entity.

     Generally, we must report to the U.S. Internal Revenue Service the amount
of dividends paid, the name and address of the recipient, and the amount, if
any, of tax withheld. A similar report is sent to the holder. Pursuant to tax
treaties or certain other agreements, the U.S. Internal Revenue Service may make
its reports available to tax authorities in the recipient's country of
residence.

     Dividends paid to a non-U.S. holder at an address within the United States
may be subject to backup withholding imposed at a rate of 31% if the non-U.S.
holder fails to establish that it is entitled to an exemption or to provide a
correct taxpayer identification number and certain other information. Under
current United States federal income tax law, backup withholding (imposed at a
rate of 31%) generally will not apply to dividends paid on or before December
31, 2000, to a non-U.S. holder at an address outside the United States (unless
the payer has knowledge that the payee is a U.S. holder). Under new regulations
applicable to payments after December 31, 2000, however, a non-U.S. holder will
be subject to backup withholding if the non-U.S. holder does not provide the
certification required in order to receive treaty benefits described above.

     GAIN ON DISPOSITION OF COMMON STOCK

     A non-U.S. holder generally will not be subject to U.S. federal income tax
with respect to gain realized on a sale or other disposition of shares of common
stock.

                                       66
<PAGE>   68

     INFORMATION REPORTING REQUIREMENTS AND BACKUP WITHHOLDING ON DISPOSITION OF
COMMON STOCK

     Under current United States federal income tax law, information reporting
and backup withholding imposed at a rate of 31% will apply to the proceeds of a
disposition of shares of common stock effected by or through a U.S. office of a
broker unless the disposing holder certifies as to its non-U.S. status or
otherwise establishes an exemption. Generally, U.S. information reporting and
backup withholding will not apply to a payment of disposition proceeds where the
transaction is effected outside the United States through a non-U.S. office of a
non-U.S. broker. However, U.S. information reporting requirements (but not
backup withholding) will apply to a payment of disposition proceeds where the
transaction is effected outside the United States by or through an office
outside the United States of a broker that is:

     -  a U.S. person,

     -  a foreign person which derives 50% or more of its gross income for
       certain periods from the conduct of a trade or business in the United
       States,

     -  a "controlled foreign corporation" for U.S. federal income tax purposes
       or

     -  in the case of payments made after December 31, 2000, a foreign
       partnership with certain connections to the United States, in each case
       unless such broker has documentary evidence in its files of the holder's
       non-U.S. status and has no actual knowledge to the contrary or unless the
       holder establishes an exemption.

     Backup withholding is not an additional tax. Rather, the tax liability of
persons subject to backup withholding will be reduced by the amount of tax
withheld. If withholding results in an overpayment of taxes, a refund may be
obtained, provided that the required information is furnished to the U.S.
Internal Revenue Service.

CERTAIN BELGIAN TAX CONSIDERATIONS FOR BELGIAN HOLDERS OF COMMON STOCK

     The following generally summarizes the material Belgian income and stamp
tax consequences of the acquisition, direct ownership and disposition of our
common stock by Belgian residents and it is based on the opinion of Stibbe
Simont Monahan Duhot, Belgian legal counsel to deCODE. This discussion is based
on tax law applicable in Belgium as in effect on the date of this prospectus,
and is subject to changes to Belgian law, including changes that could have
retroactive effect. The following summary does not take into account or discuss
tax laws of any country other than Belgium nor does it take into account the
individual circumstances of each investor.

     Prospective Belgian investors are advised to consult their own tax advisers
as to the tax consequences of the acquisition, ownership and disposition of our
common stock.

     BELGIAN WITHHOLDING TAX

     Dividends distributed on our common stock (gross of Belgian taxation but
net of any foreign withholding tax deducted) are subject to Belgian dividend
withholding tax at the rate of 25.0% when paid or attributed through an
intermediary in Belgium. However, no Belgian dividend withholding tax is due if
the Belgian resident is a company subject to Belgian corporation income tax,
provided certain formalities are met.

     To the extent that dividends on our common stock are attributed or paid
outside Belgium, without the intervention of a paying agent or any other
financial intermediary in Belgium, no Belgian dividend withholding tax is due.
However, Belgian resident entities subject to Belgian legal entities tax (such
as pension funds) must pay the dividend withholding tax to the Belgian Treasury.

     The withholding tax may be subject to exemptions or reductions provided by
Belgian law. For instance, in certain cases the above-mentioned 25% rate of
dividend withholding tax will be reduced to 15%. The reduced rate applies in
particular to:

     -  dividends distributed on shares publicly issued on or after January 1,
        1994; and

                                       67
<PAGE>   69

     -  dividends distributed on shares that have been privately issued on or
        after January 1, 1994 in exchange for cash contributions, provided the
        shares are registered, or are bearer shares placed in open custody, to a
        financial institution in Belgium as of the date of their issuance.

     INCOME TAX FOR BELGIAN RESIDENT INDIVIDUALS

     The Belgian dividend withholding tax is a final tax for Belgian resident
individuals holding our common stock as a private investment, and the dividends
need to be reported in such individuals' annual income tax returns. If no
withholding tax has been levied (for example where payment or attribution is
made outside Belgium), such individuals are required to report the dividends in
their tax returns, and will be taxed at the rate of either 25.0% or 15.0%, in
each case increased by a municipal surcharge (generally varying from 5% to 8% of
the tax due).

     Belgian resident individuals whose holdings of our common stock are
connected with a business will be taxed on the dividends at the ordinary rates
for business income, varying from 25% to 55% and increased by the appropriate
municipal surcharge and a 3% crisis contribution. Any Belgian withholding tax is
creditable against the final income tax due, provided the holder of our common
stock has full ownership of that stock at the time of attribution or payment of
the dividends and the dividend distribution does not entail a reduction in value
or capital loss on the shares.

     CORPORATE INCOME TAX FOR COMPANIES RESIDENT IN BELGIUM

     Dividends received by companies resident in Belgium are, in principle,
subject to corporation income tax at the rate of 40.1%, i.e. the standard rate
of 39%, increased by the additional tax of 3% of the corporate income tax due.
Lower rates may be applicable to Belgian resident companies which, among other
conditions, are not 50% or more owned by another company and whose taxable
income is below certain thresholds fixed by law.

     Belgian resident companies which satisfy the minimum holding requirement of
either a participation of at least 5% in deCODE or an acquisition value of at
least BEF50 million at the time of attribution or payment of dividends will be
taxed on only 5% of the dividends received (so-called dividends-received
deductions or DRD) unless deCODE falls within one of the categories expressly
excluded from the DRD. DRD entitlement is assessed on a case by case basis at
the time of attribution by reference to the origin of the issuer's revenue used
to distribute the dividend. If our revenues continue to be submitted to normal
taxation, it is highly unlikely that DRD would be denied.

     INCOME TAX FOR BELGIAN RESIDENT ENTITIES SUBJECT TO BELGIAN LEGAL ENTITIES
TAX

     The Belgian dividend withholding tax is a final tax for Belgian resident
entities subject to the Belgian legal entities tax.

     BELGIAN CAPITAL GAINS TAXATION

     Income Tax for Individuals Resident in Belgium.  Individuals holding our
common stock as a private investment will not be subject to Belgian capital
gains taxation on the disposal of that stock. Individuals may, however, be
subject to a 33% tax (increased by the appropriate municipal surcharge and the
3% crisis contribution) if the capital gain is deemed to be "speculative" in
nature as defined by Belgian case law.

     Corporate Income Tax for Companies Resident in Belgium.  Capital gains
realized by companies resident in Belgium on the disposal of our common stock
are exempt from Belgian capital gains taxation if our dividends fully qualify
for the DRD. It is not necessary to satisfy the minimum holding requirement for
DRD to benefit from this exemption.

     Capital losses are only tax-deductible on a liquidation and distribution of
all our assets and liabilities. In that event, capital losses are tax-deductible
to the extent that they represent fully paid-up capital.

     Belgium Resident Entities Subject to the Belgian Legal Entities
Tax.  Entities subject to the Belgian legal entities tax are not subject to
Belgian capital gains taxation on the disposal of our common stock.

                                       68
<PAGE>   70

     BELGIAN INDIRECT TAXES

     Stamp Tax on Securities Transactions.  In principle, a Belgian stamp tax is
levied upon the subscription or purchase or sale of our common stock in Belgium
through a professional intermediary. The rate applicable to subscriptions for
new shares is 0.35% subject to an upper limit of BEF 10,000 or (Euro 248) per
transaction. The rate applicable to sales and purchases of existing shares in
Belgium through a professional intermediary is 0.17% subject to an upper limit
of BEF 10,000 or (Euro 248) per transaction.

     An exemption is available to professional intermediaries (such as credit
institutions), insurance companies, pension funds and collective investment
vehicles acting for their own account. Non-Belgian resident holders of our
common stock acting for their own account will also be entitled to an exemption
from this stamp tax if they deliver to the issuer of the professional
intermediary in Belgium, as the case may be, an affidavit confirming non-
Belgian resident status.

     Tax on Physical Delivery of Bearer Securities.  A tax is levied upon the
physical delivery of our common stock pursuant to the subscription or
acquisition for consideration in Belgium. This tax is also due on the delivery
of our common stock pursuant to a withdrawal of such stock from "open custody"
in Belgium. An exemption is available if the acquisition for consideration does
not take place through a professional intermediary.

     This tax is due, at the rate of 0.2% on the sums payable by the subscriber
or acquirer on a subscription of acquisition of the sales value of our common
stock, as estimated by the custodian, on a withdrawal from "open custody."

     An exemption is available for deliveries to recognized professional
intermediaries (such as credit institutions) acting for their own account. An
exemption is also available for delivery to a non-resident of shares of our
common stock which are held in "open custody" with certain specified financial
intermediaries.

     Since securities listed on EASDAQ are always in book entry form, the
Belgian tax on the physical delivery of bearer securities will not apply to
transactions in our common stock on EASDAQ.

                        SHARES ELIGIBLE FOR FUTURE SALE

     Prior to this offering there has been no public market for our common
stock. Some financial institutions have been making a market for
privately-negotiated transactions among non-U.S. persons in shares of our
outstanding Series B preferred stock. Our Series B preferred stock transfer
records indicate that approximately 10 million shares of Series B preferred
stock were transferred during 1999 in approximately 7,000 transactions and
approximately 1.1 million shares of Series B preferred stock were transferred
during January 2000 in approximately 2,700 transactions. The majority of these
transactions had an Icelandic financial institution as one of the
counterparties. Future sales of substantial amounts of our common stock, or even
the possibility of such sales, could reduce the prevailing market price. As
described below, only a limited number of shares of common stock currently held
by our stockholders will be available for sale shortly after this offering due
to certain contractual and legal restrictions on resale. Sales of substantial
amounts of common stock in the public market after the restrictions lapse could
adversely affect the prevailing market price and our ability to raise equity
capital in the future.

     Upon closing of this offering,    --   shares of our common stock will be
outstanding based on the number of shares of our preferred stock and common
stock outstanding as of December 31, 1999, and assuming no exercise of the
underwriters' over-allotment option. Of these shares, the    --   shares of
common stock being sold in this offering will be freely tradable (unless
purchased by an "affiliate" of deCODE as such term is defined in the Securities
Act of 1933 without restriction or registration under the Securities Act. All
remaining shares of common stock were issued and sold in private transactions
and are "restricted securities" which are eligible for public sale only if
registered under the Securities Act or sold in accordance with Rule 144
promulgated under that Act. In addition, upon closing of this offering 2,125,037
shares of common stock will be issuable upon the exercise of warrants and
options.

     Each of deCODE and the directors, executive officers and certain other
stockholders of deCODE (who will hold, in the aggregate,  -- % of deCODE's
common stock after the offering) has agreed that, without the prior written
consent of Morgan Stanley & Co. Incorporated on behalf of the underwriters, it
will not sell its shares during the period ending 180 days after the date of
this prospectus.

     Each of certain other stockholders of deCODE, (who will hold, in the
aggregate,  -- % of deCODE's common stock after the offering), has signed an
agreement providing that, upon the request of deCODE or Morgan Stanley & Co.
Incorporated, it will not, during the period ending 180 days after the effective
date of the registration statement of which this prospectus is a part, sell or
otherwise transfer or dispose of any shares of common stock. We cannot be
certain that such agreements can be enforced against all transferees of the
initial purchasers of the shares.

     As a result of lockups with the underwriters and the provisions of Rule
144, the      --     shares which are restricted securities will be available
for sale in the U.S. public market as follows:

     -       --     shares of common stock will be immediately eligible for
        resale upon expiration of the lockup period (subject to the volume
        limitations of Rule 144 in the case of sales by affiliates)

     -       --     shares of common stock will be immediately eligible for
        resale upon expiration of the lockup period (subject to the volume
        limitations of Rule 144)

     -       --     shares of common stock will be eligible for resale from time
        to time thereafter upon expiration of the applicable holding periods
        under Rule 144 upon expiration of the lockup period (subject to the
        volume limitations of Rule 144)

     Rule 144.  In general, under Rule 144 as currently in effect, beginning 90
days after the date of this prospectus a person or persons whose shares are
aggregated, who has beneficially owned restricted securities for at least one
year, including the holding period of any prior owner except an affiliate, will
be entitled to sell within any three-month period a number of shares that does
not exceed the greater of:

     -  1% of the number of shares of our common stock then outstanding, which
        will equal approximately    --   shares immediately after this offering;
        or

                                       70
<PAGE>   72

     -  the average weekly trading volume of our common stock on the Nasdaq
        National Market during the four calendar weeks preceding the filing of a
        notice on Form 144 with respect to the sale.

     Sales under Rule 144 are also subject to manner of sale provisions and
notice requirements and to the availability of current public information about
deCODE.

     Rule 144(k).  Under Rule 144(k), a person who is not deemed to have been
one of our affiliates at any time during the three months preceding a sale, and
who has beneficially owned the shares proposed to be sold for at least two
years, including the holding period of any prior owner except an affiliate, is
entitled to sell these shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.

     Registration Rights.  As described above, holders of   --  shares of our
common stock which are restricted securities will be entitled to demand
registration of their shares under the Securities Act at any time after 180 days
after the effective date of the registration statement of which this prospectus
is a part. Registration of these shares under the Securities Act would result in
their becoming freely tradeable without restriction under the Securities Act,
except for shares purchased by affiliates, immediately upon the effectiveness of
the registration.

     The underwriters are offering the shares of common stock subject to their
acceptance of the shares from deCODE and subject to prior sale. The underwriting
agreement provides that the obligations of the several underwriters to pay for
and accept delivery of the shares of common stock offered by this prospectus are
subject to the approval of certain legal matters by their counsel and to certain
other conditions. The underwriters are obligated to take and pay for all of the
shares of common stock offered by this prospectus if any such shares are taken.
However, the underwriters are not required to take or pay for the shares covered
by the underwriters' over-allotment option described below.

     The underwriters initially propose to offer part of the shares of common
stock directly to the public at the public offering price listed on the cover
page of this prospectus and part to certain dealers at a price that represents a
concession not in excess of $   --   a share under the public offering price.
Any underwriter may allow, and such dealers may reallow, a concession not in
excess of $   --   a share to other underwriters or to certain dealers. After
the initial offering of the shares of common stock, the offering price and other
selling terms may from time to time be varied by the representative.

     Morgan Stanley & Co. Incorporated expects to deliver the shares to
purchasers on    --   , 2000.

     deCODE has granted to the underwriters an option to purchase up to an
aggregate of    --   additional shares of common stock exercisable for 30 days
from the date of this prospectus, at the public offering price listed on the
cover page of this prospectus, less underwriting discounts and commissions. The
underwriters may exercise this option solely for the purpose of covering
overallotments, if any, made in connection with the offering of the shares of
common stock offered by this prospectus. To the extent the option is exercised,
each underwriter will become obligated, subject to certain conditions, to
purchase approximately the same percentage of the additional shares of common
stock as the number listed next to the underwriter's name in the preceding table
bears to the total number of shares of common stock listed next to the names of
all underwriters in the preceding table. If the underwriters' option is
exercised in full, the total price to the public will be $   --   , the total
underwriters' discounts and commissions will be $   --   and total proceeds to
deCODE will be $   --   .

     The underwriters have informed deCODE that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
common stock offered by them.

     The common stock has been approved for quotation, subject to official
notice of issuance, on the Nasdaq National Market and on EASDAQ, in each case
under the symbol "DCGN."

     Each of deCODE and the directors, executive officers and certain other
stockholders of deCODE (who will hold, in the aggregate,  -- % of deCODE's
common stock after the offering) has agreed that, without the prior written
consent of Morgan Stanley & Co. Incorporated on behalf of the underwriters, it
will not during the period ending 180 days after the date of this prospectus:

     -  offer, pledge, sell, contract to sell, sell any option or contract to
        purchase, purchase any option or contract to sell, grant any option,
        right or warrant to purchase, lend or otherwise transfer or dispose of

                                       72
<PAGE>   74

       directly or indirectly, any shares of common stock or any securities
       convertible into or exercisable or exchangeable for common stock; or

     -  enter into any swap or other arrangement that transfers to another, in
        whole or in part, any of the economic consequences of ownership of the
        common stock,

whether any transaction described above is to be settled by delivery of common
stock or such other securities, in cash or otherwise.

     The restrictions described in the paragraph above do not apply to:

     -  the sale of shares to the underwriters;

     -  the issuance by deCODE of shares of common stock upon the exercise of an
        option or a warrant or the conversion of a security outstanding,
        authorized or available for grant on the date of this prospectus of
        which the underwriters have been advised in writing; or

     -  transactions by any person other than deCODE relating to shares of
        common stock or other securities acquired in open market transactions
        after the completion of the offering of the shares.

     Each of certain other stockholders of deCODE, (who will hold, in the
aggregate,  -- % of deCODE's common stock after the offering), signed an
agreement providing that, upon the request of deCODE or Morgan Stanley & Co.
Incorporated, it will not, during the period ending 180 days after the effective
date of the registration statement of which this prospectus is a part, sell or
otherwise transfer or dispose of any shares of common stock. deCODE made such
request on    --   . We cannot be certain that such agreements can be enforced
against all transferees of the initial purchasers of the shares.

     Any deCODE stockholder holding registration rights cannot require deCODE to
register its stock earlier than 180 days after the date of this prospectus.
These registration rights may not, therefore, be used as a reason to break-up
any lock-up arrangements described above.

     In order to facilitate the offering of the common stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the common stock. Specifically, the underwriters may over-allot in
connection with the offering, creating a short position in the common stock for
their own account. In addition, to cover over-allotments or to stabilize the
price of the common stock, the underwriters may bid for, and purchase, shares of
the common stock in the open market. Finally, the underwriting syndicate may
reclaim selling concessions allowed to an underwriter or a dealer for
distributing the common stock in the offering, if the syndicate repurchases
previously distributed common stock in transactions to cover syndicate short
positions, in stabilization transactions or otherwise. Any of these activities
may stabilize or maintain the market price of the common stock above independent
market levels. The underwriters are not required to engage in these activities,
and may end any of these activities at any time.

     deCODE and the underwriters have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act.

PRICING OF THE OFFERING

     Prior to this offering, there has been no public market for the common
stock. Some Icelandic financial institutions have been making a market for
privately negotiated transactions among non-U.S. persons in shares of our
outstanding Series B preferred stock. The initial public offering price of the
common stock will be determined by negotiations between deCODE and the
representative. Among the factors to be considered in determining the initial
public offering price will be the future prospects of deCODE and its industry in
general, earning and certain other financial operating information of deCODE in
recent periods, and the price-earnings ratios, price-sales ratios, market prices
of securities and certain financial and operating information of companies
engaged in activities similar to those of deCODE. The estimated initial public
offering price range set forth on the cover page of this preliminary prospectus
is subject to change as a result of market conditions and other factors.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and stockholders of deCODE genetics, Inc.:

     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, changes in stockholders' equity
and cash flows present fairly, in all material respects, the consolidated
financial position of deCODE genetics, Inc. ("deCODE") at December 31, 1998 and
1999 and the consolidated results of its operations and its consolidated cash
flows for each of the three years in the period ended December 31, 1999, in
conformity with generally accepted accounting principles in the United States.
These financial statements are the responsibility of deCODE's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards in the United States, which require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A.  DESCRIPTION OF BUSINESS:

     deCODE genetics, Inc. ("deCODE") is a genomics and health informatics
company which applies and develops modern informatics to collect and analyze
data about the Icelandic population in order to develop products and services
for the healthcare industry. deCODE was founded in 1996 and its facilities are
located in Reykjavik, Iceland, where all of deCODE's operations take place.

     In November 1996, deCODE acquired all of the then outstanding shares and
assumed the related liabilities of deCODE ehf. which was subsequently renamed
Islensk erfethagreining ehf. deCODE ehf. was founded in December 1995 by certain
of the same founding stockholders of deCODE. From inception to the date of
acquisition by deCODE, deCODE ehf. had been engaged in the early assessment of
the feasibility of utilizing genomics to aid in drug discovery.

     Through February 1998, deCODE was a development stage enterprise as defined
by Statement of Financial Accounting Standards No. 7, "Accounting and Reporting
by Development Stage Enterprises." On February 1, 1998, deCODE entered into a
research and collaboration agreement with the Swiss pharmaceutical and
diagnostic company F.Hoffmann-La Roche ("Roche"), under which deCODE may receive
a total of more than $200 million in equity contributions, research funding and
milestone payments. This agreement covers research of up to twelve disease
categories over a period of up to five years. As a part of this relationship,
Roche has made capital investments in deCODE, provides funding for ongoing
research and has made cash payments upon the achievement of certain research
milestones.

B.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

     BASIS OF PRESENTATION

     These financial statements are reported in United States dollars, deCODE's
functional currency, and prepared in accordance with generally accepted
accounting principles in the United States.

     PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts and operations
of deCODE and its wholly owned subsidiary. All significant intercompany accounts
and transactions are eliminated upon consolidation. The investment in affiliate
in which deCODE has significant influence, but does not control, is accounted
for using the equity method.

     USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.

     UNCERTAINTIES

     deCODE is subject to risks common to companies in the biotechnology
industry including, but not limited to, development by deCODE or its competitors
of new technological innovations, ability to market products or services,
dependence on key personnel, dependence on key suppliers, protection of
proprietary technology, ability to obtain additional financing, ability to
negotiate collaborative arrangements and compliance with governmental and other
regulations.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     CONCENTRATION OF RISK

     Financial instruments that potentially subject deCODE to concentrations of
credit risk consist principally of temporary cash investments. deCODE's cash is
deposited only with financial institutions in Iceland and the United States
having a high credit standing.

     FAIR VALUE OF FINANCIAL INSTRUMENTS

     The fair value of short-term financial instruments, including cash and cash
equivalents, receivables, certain other current assets, trade accounts payable,
certain accrued liabilities, and other current liabilities approximates their
carrying amount in the financial statements mainly due to the short maturity of
such instruments.

     The fair value of capital lease obligations and other long-term liabilities
approximate their carrying amounts based on deCODE's estimated current
incremental borrowing rate for similar obligations with similar terms.

     CASH EQUIVALENTS

     deCODE considers all highly liquid investments with a maturity of 90 days
or less at the date of purchase to be cash equivalents.

     PROPERTY AND EQUIPMENT

     Property and equipment are recorded at cost. Depreciation is computed using
the straight-line method over the estimated useful lives of the related assets
of generally three years for computer equipment, five years for laboratory
equipment, furniture, fixtures and company cars, and fifty years for buildings.
Maintenance and repairs are expensed as incurred, while major betterments are
capitalized. When assets are retired or otherwise disposed of, the assets and
related accumulated depreciation or amortization are eliminated from the
accounts and any resulting gain or loss is reflected in the statement of
operations.

     IMPAIRMENT OF LONG-LIVED ASSETS

     As appropriate, management determines whether any property or equipment has
been impaired based on the criteria established by Statement of Financial
Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived
Assets and Long-Lived Assets to be Disposed Of." deCODE has made no adjustments
to the carrying values of property and equipment during the years ended December
31, 1997, 1998 and 1999.

     CAPITAL LEASES

     Assets acquired under capital lease agreements are recorded at the present
value of the future minimum rental payments using interest rates appropriate at
the inception of the lease. Property and equipment subject to capital lease
agreements are amortized over the shorter of the life of the lease or the
estimated useful life of the asset, in accordance with deCODE's normal
depreciation policies, unless the lease transfers ownership or contains a
bargain purchase option, in which case the leased asset is amortized over the
estimated useful life of such asset.

     REVENUE RECOGNITION AND DEFERRED REVENUE

     On December 3, 1999, the staff of the Securities and Exchange Commission
issued Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial
Statements" (SAB 101), that summarizes the staff's views in applying generally
accepted accounting principles to revenue recognition in financial statements.
The accounting and disclosure requirements that are described in SAB 101 apply
to all registrants. deCODE has adopted the requirements of SAB 101 and has
restated prior years in accordance with the going public exemption under
Accounting Principles Board Opinion No. 20, "Accounting Changes."

                             DECODE GENETICS, INC.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     deCODE's revenues are currently derived primarily from research funding
under the research and collaboration agreement with Roche. Research funding
revenue is recognized on an accrual basis as services are provided and are
recorded with reference to contracted rates. Milestone payments are recorded
when acknowledgement of having achieved applicable performance requirements is
received from the joint steering committee and are recognized as revenue on a
retrospective straight-line basis over the contractual term of the agreement
with Roche. Accordingly, payments received in advance of being earned are
recorded as deferred revenue.

     RESEARCH AND DEVELOPMENT

     All research and development costs are expensed as incurred.

     STOCK-BASED COMPENSATION

     deCODE follows Statement of Financial Accounting Standards No. 123 (SFAS
No. 123), "Accounting for Stock-Based Compensation." The provisions of SFAS No.
123 allow companies to either expense the estimated fair value of stock options
granted or to follow the intrinsic value method set forth in Accounting
Principles Board Opinion No. 25 (APB No. 25), "Accounting for Stock Issued to
Employees," and disclose the pro forma effects on net loss and net loss per
share had the estimated fair value of the options been expensed. deCODE has
elected to follow the intrinsic value method in accounting for its stock option
incentive plans.

     FOREIGN CURRENCY TRANSLATION

     deCODE and its wholly-owned subsidiary use the U.S. dollar as the
functional currency. deCODE's wholly-owned subsidiary also consolidates its
subsidiaries, all of which use the local currency, the Icelandic krona, as the
functional currency. For these entities the assets and liabilities are
translated into U.S. dollars at exchange rates in effect at the balance sheet
date. Income and expense items are translated at the average exchange rates
prevailing during the period. Gains and losses from translation are included in
accumulated other comprehensive income (loss).

     INCOME TAXES

     deCODE accounts for income taxes using the liability method, which requires
the recognition of deferred tax assets or liabilities for the temporary
differences between the financial reporting and tax bases of deCODE's assets and
liabilities and for tax carryforwards at enacted statutory tax rates in effect
for the years in which the difference are expected to reverse. In addition,
valuation allowances are established when necessary to reduce deferred tax
assets to the amounts expected to be realized.

     COMPUTATION OF NET LOSS PER COMMON SHARE

     Net loss per share is computed under Statement of Financial Accounting
Standards No. 128, "Earnings Per Share." Basic net loss per share is computed
using net loss available to common stockholders and the weighted-average number
of common shares outstanding. The weighted-average number of common shares
outstanding during the period is the number of shares determined by relating the
portion of time within a reporting period that common shares have been
outstanding to the total time in that period.

</TABLE>

     The Series B preferred stock is not redeemable and events that would lead
to a constructive liquidation of deCODE, as defined, are remote. As such,
dividends are not accreted on the Series B preferred stock.

     The premium on repurchase of preferred stock arises as a result of deCODE's
repurchase of Series A, Series B and Series C preferred stock in August 1999 and
represents the aggregate difference between the adjusted repurchase price and
the then carrying value of the Series A, Series B and Series C preferred stock.

     Diluted net loss per share is computed using the weighted-average number of
common shares outstanding during the period, plus the dilutive effect of
potential common shares. Diluted net loss per share does not differ from basic
net loss per share since potential common shares from the conversion of
preferred stock, stock options and warrants are antidilutive for all periods
presented and are, therefore, excluded from the calculation. For the years ended
December 31, 1997, 1998, and 1999, preferred stock convertible into 11,790,375,
19,125,683 and 22,969,544 shares of common stock, respectively, options to
purchase 1,180,000, 47,000 and 45,000 shares of common stock, respectively, and
warrants to purchase 1,137,814, 1,998,926 and 2,110,037 shares of preferred
stock, respectively, were not included in the computation of diluted loss per
share since their inclusion would be antidilutive.

     UNAUDITED PRO FORMA STOCKHOLDERS' EQUITY

     Upon the closing of a qualified initial public offering, all of the
outstanding shares of Series A, Series B and Series C preferred stock, will
automatically convert into 22,969,544 shares of common stock. These conversions
have been reflected in unaudited pro forma stockholders' equity at December 31,
1999.

     UNAUDITED PRO FORMA NET LOSS PER SHARE

     Unaudited pro forma basic and diluted net loss per share have been
calculated assuming the conversion of all outstanding shares of preferred stock
into common stock, as if the preferred shares had converted immediately upon
their issuance. Accordingly, in the calculation of unaudited pro forma net loss
per share, net loss has not been increased for the accumulated dividends or
amortized discounts on preferred stock or for the premium on the repurchase of
preferred stock. The calculation of unaudited pro forma net loss per share is as
follows:

     SEGMENT INFORMATION

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131 (SFAS No. 131), "Disclosures About
Segments of an Enterprise and Related Information." This statement requires
companies to report information about operating segments in interim and annual
financial statements. It also requires segment disclosures about products and
services, geographic areas and major customers. deCODE adopted SFAS No. 131
effective for its fiscal year ended December 31, 1998. deCODE has determined
that it did not have any separately reportable operating segments as of December
31, 1998 or 1999.

     All of deCODE's revenues from inception through December 31, 1999 have been
generated in Iceland, and all of deCODE's long-lived assets are located in
Iceland. In 1998 and 1999, one customer, Roche, accounted for 100% and 96% of
revenues, respectively.

     RECENT ACCOUNTING PRONOUNCEMENT

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 (SFAS No. 133), "Accounting for
Derivative Instruments and Hedging Activities." This standard establishes a new
model for accounting for derivatives and hedging activities and supersedes and
amends a number of existing standards. Upon the standard's initial application,
all derivatives are required to be recognized in the balance sheet as either
assets or liabilities and measured at fair value. In addition, all hedging
relationships must be designated, reassessed and documented. Currently, the
standard is to be effective for fiscal years and quarters beginning after June
15, 2000. Considering deCODE's current activities, it is not anticipated that
the adoption of SFAS No. 133 will have a significant impact on its financial
position or results of operations.

C.  INVESTMENTS:

     In January and February 1999, deCODE acquired equity interests totalling
20% in Gagnalind hf. in exchange for $254,444 in cash and 70,824 shares of
Series B preferred stock. In November 1999, deCODE entered into an agreement to
acquire an approximate 20% equity interest in eMR ehf. in exchange for deCODE's
interest in Gagnalind hf. and $344,590 in cash. This transaction is expected to
be completed in early 2000. In connection with this agreement, deCODE issued
68,000 shares of common stock in exchange for additional shares in Gagnalind hf.
which temporarily increased deCODE's equity interest in Gagnalind hf. to 56% at
December 31, 1999. The carrying amount of deCODE's investment in Gagnalind hf.
approximates deCODE's underlying equity in the net assets of Gagnalind hf.

     deCODE's equity in net earnings (loss) of affiliate, Gagnalind hf., for the
year ended December 31, 1999 is comprised of deCODE's share of the earnings of
Gagnalind hf. and amortization of the difference between deCODE's cost and the
underlying equity in the net assets of Gagnalind hf. at acquisition.

D.  PROPERTY AND EQUIPMENT:

     Property and equipment, all located in Iceland, consisted of the following:

     The total depreciation and amortization for the years ended December 31,
1997, 1998 and 1999 was, $513,055, $1,470,959 and $2,767,521, respectively.

     Property and equipment includes amounts for certain fixed assets financed
under capital lease obligations. Total cost and accumulated amortization
relating to property and equipment subject to capital lease obligations was
$10,624,985 and $1,601,675, respectively, as of December 31, 1998, and
$10,624,985 and $3,336,034, respectively, as of December 31, 1999.

     deCODE's capital lease obligations are collateralized by the assets to
which the obligations relate. deCODE has an option to purchase all of the leased
property and equipment for 3% of the original lease amount at lease end.

</TABLE>

     At December 31, 1997, some of deCODE's capital lease obligations were
collateralized by an amount of cash on deposit with an Icelandic bank
($1,595,769 at December 31, 1997). The requirement for the deposited amount was
removed by the leasing company in 1998.

     SETTLEMENT AGREEMENT

     On December 31, 1997, deCODE entered into a settlement agreement in respect
of the past use of certain research facilities (the "Agreement"). As a part of
the Agreement, deCODE paid fees both in the form of cash and the issuance of
Series A preferred stock. In connection with the Agreement, on January 1, 1998,
deCODE issued 100,000 shares of Series A preferred stock. Further, on December
31, 1998 and 1999, deCODE issued 20,000 shares and 10,000 shares of Series A
preferred stock, respectively. The amounts paid and the value of the shares
issued have been expensed in the statement of operations.

     Under the Agreement, deCODE is obligated to make certain payments upon the
achievement of established milestones leading to the discovery of defined
products. deCODE is also to pay royalties on certain royalty bearing products
which may result. Such royalties are to be paid for a period up to and
potentially exceeding 15 years.

     COLLABORATIVE PARTIES

     deCODE has established collaborations in Iceland in most of the disease
categories in which the company works. These collaborations generally extend for
periods of up to five years, with deCODE being committed to make various
payments in connection with research and other services provided as well as to
pay the collaborators a portion of sales of scientific results to a third party
or of commercial royalties and commercial payments received by deCODE.

     Subject to satisfactory performance of a consulting arrangement, deCODE is
committed to grant stock options for 15,000 shares on December 1, 2000 at an
exercise price equal to the fair market value on the date of grant.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Certain of the collaborative agreements stipulate future payments in
respect of services provided to deCODE. These future payments are included in
current and long-term liabilities in the accompanying balance sheets.

     LITIGATION

     In January 2000, a lawsuit was filed against deCODE and another Icelandic
company alleging copyright infringement and claiming damages amounting to
approximately $9,000,000. deCODE believes the suit is without merit and intends
to defend this action vigorously; however, the ultimate resolution of this
matter cannot yet be determined.

     In January and February 2000, two individuals advised deCODE that they
believe they are entitled to shares of deCODE's common stock. deCODE believes
these assertions are entirely without merit and intends to defend any actions
which these parties may commence vigorously; however, the ultimate resolution of
these matters cannot be determined.

     In February 2000, an organization known as The Association of Icelanders
for Ethics in Science and Medicine, or Mannvernd, and a group of physicians and
other citizens issued a press release announcing their intention to file
lawsuits against the State of Iceland and any other relevant parties, including
deCODE, to test the constitutionality of the Act on a Health Sector Database no.
139/1998, or the Act. According to the press release, the intended lawsuit will
allege that the Act and the IHD license involve human rights violations and will
challenge the validity of provisions of the Act which allow the use of presumed
consent for the processing of health data into the IHD and the grant of a
license to operate a single database. deCODE believes that any such litigation
would be without merit and intends to defend vigorously any such action in which
it becomes a party. However, in the event that the Icelandic State by a final
judgment is found to be liable or subject to payment to any third party as a
result of the passage of legislation on the IHD and/or the issuance of the IHD
license, our agreement with the Ministry requires us to indemnify (see note M)
the State of Iceland against all damages and costs incurred in connection with
such litigation.

H.  REDEEMABLE, CONVERTIBLE PREFERRED STOCK:

     deCODE is authorized to issue 32,641,926 shares of preferred stock. The
preferred stock can be issued in one or more series. The outstanding shares of
preferred stock issued are convertible, at the option of the holder, into common
stock at any time, at the applicable conversion rate as adjusted from time to
time (one-to-one at the date of issuance). Upon such optional conversion, deCODE
shall pay any accumulated, unpaid dividends, whether or not declared by the
Board of Directors. The preferred stock automatically converts to common stock
upon closing of a qualified initial public offering, as defined by deCODE's
Amended and Restated Certificate of Incorporation. Upon such automatic
conversion, all accumulated, unpaid dividends will be cancelled. Common stock
that would be received upon an optional or automatic conversion would carry with
it certain registration rights. In addition, the preferred stock contains
constructive liquidation provisions whereby the occurrence of certain defined
events are deemed to be liquidations of deCODE. The liquidation value is the sum
of the original issue price plus any accumulated, unpaid dividends before any
distributions to the holders of common stock.

     A description of the preferred stock outstanding on December 31, 1999 is as
follows:

     SERIES A

     As of December 31, 1999, deCODE has issued and outstanding 9,562,301 shares
of Series A preferred stock. Holders of Series A preferred stock are entitled to
receive, when and as declared by the Board of Directors, cash dividends at the
rate of 8% of the original issue price per annum. Series A preferred stock
dividends are cumulative and receive preference over dividends on any
outstanding shares of common stock. Upon liquidation, dissolution or winding-up
of deCODE, the holders of Series A preferred stock are entitled to receive the
sum of

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

the original issue price plus any accumulated, unpaid dividends before any
distributions to the holders of common stock. The Series A preferred stock is
redeemable upon the vote of 75% of the shareholders voting as a separate class,
beginning on the seventh anniversary of the earliest issue date and ending three
years later. The redemption value is the sum of the original issue price plus
any accumulated, unpaid dividends.

     Accumulated, accreted dividends on Series A preferred stock amounted to
$1,738,233 and $2,069,888 at December 31, 1998 and 1999, respectively.

     In connection with the sale of 5,090,376 shares of Series A preferred stock
in October 1997, deCODE issued 1,137,814 warrants to purchase Series A preferred
stock for $1.00 per share. The total consideration received under the issuance
was allocated between the preferred shares and the warrants based upon their
relative fair values at the date of issuance. The consideration allocated to the
warrants was $650,240, and the resulting discount on the preferred shares is
being amortized over seven years, the earliest redemption date of the Series A
preferred stock. These warrants expire on August 26, 2005.

     SERIES B

     As of December 31, 1999, deCODE has issued and outstanding 9,893,814 shares
of Series B preferred stock. Holders of Series B preferred stock are entitled to
receive, when and as declared by the Board of Directors, cash dividends at the
rate of 8% of the original issue price per annum. Series B preferred stock
dividends are cumulative and receive preference over dividends on any
outstanding shares of common stock. Upon liquidation, dissolution or winding-up
of deCODE, the holders of Series B preferred stock are entitled to receive the
sum of the original issue price plus any accumulated, unpaid dividends before
any distributions to the holders of common stock.

     Cumulative, undeclared dividends on Series B preferred stock amounted to
$1,113,560 and $5,379,772 at December 31, 1998 and 1999, respectively. Such
dividends will not be recorded until declared.

     SERIES C

     As of December 31, 1999, deCODE has issued 3,611,000 shares of Series C
preferred stock and, of those, 3,511,111 shares are outstanding. Holders of
Series C preferred stock are entitled to receive, when and as declared by the
Board of Directors, cash dividends at the rate of 8% of the original issue price
per annum. Series C preferred stock dividends are cumulative and receive
preference over dividends on any outstanding shares of common stock. Upon
liquidation, dissolution or winding-up of deCODE, the holders of Series C
preferred stock are entitled to receive the sum of the original issue price plus
any accumulated, unpaid dividends before any distributions to the holders of
common stock. The Series C preferred stock is redeemable upon the vote of 75% of
the shareholders voting as a separate class, beginning on the seventh
anniversary of the earliest issue date and ending three years later. The
redemption value is the sum of the original issue price plus any accumulated,
unpaid dividends.

     Accumulated, accreted dividends on Series C Preferred Stock amounted to
$363,835 and $935,291 at December 31, 1998 and 1999, respectively.

     Pursuant to a stock and warrant purchase agreement signed in February 1998,
Roche purchased 2,500,000 shares of Series C preferred stock at $2.00 per share
in February 1998, purchased 555,555 additional shares of Series C preferred
stock at $3.00 per share in February 1999, and purchased another 555,556 shares
of Series C preferred stock at $3.00 per share in May 1999. In connection with
these share purchases, Roche also obtained options and warrants to purchase a
total of 972,223 shares of Series C preferred stock for a weighted-average
exercise price of $3.37 per share. The total consideration received under these
issuances was allocated between the preferred shares and the warrants based upon
their relative fair values at the dates of issuance.

     The consideration allocated to the 861,112 options and warrants issued in
February 1998 was $400,250, and the resulting discount on the preferred shares
is being amortized over seven years, the earliest redemption date of the Series
C preferred stock. Options and warrants to purchase 611,112 shares expire on
February 1, 2001, and warrants to purchase 250,000 shares expire on February 2,
2007.

     The consideration allocated to the 55,555 warrants issued in February 1999
was $41,668, and the resulting discount on the preferred shares is being
amortized over seven years, the earliest redemption date of the Series C
preferred stock. These warrants expire on February 5, 2008.

     The consideration allocated to the 55,556 warrants issued in May 1999 was
$125,804 resulting in the shares being issued at a discount. As the preferred
shares issued with these warrants were issued with beneficial conversion
features, the remaining consideration to be allocated was recorded as additional
paid-in capital resulting in no consideration being allocated to the preferred
shares. This resulting discount on the preferred shares was amortized entirely
on the date of issuance, as the preferred shares are convertible upon issuance.
These warrants expire on May 20, 2009.

     ISSUANCE OF SERIES B PREFERRED STOCK

     On June 30, 1999, deCODE entered into a Stock Purchase Agreement (the
"Purchase Agreement") to sell five million shares of Series B preferred stock at
$7.50 per share (the "Purchase Price") to a Luxembourg-based financial buyer
(the "Buyer"). The sale closed on August 8, 1999.

     Contemporaneously with the execution of the Purchase Agreement, deCODE and
the Buyer entered into an agreement pursuant to which the parties agreed upon
the following:

     -  Sales of Series B preferred stock in the Icelandic market shortly before
        the date of the Purchase Agreement indicated that the market price was
        approximately $15 per share;

     -  The Buyer would sell the Series B preferred stock to Icelandic investors
        at the market price;

     -  The Purchase Price at which the Buyer would buy the Series B shares from
        deCODE would be increased to $15.00 per share (the "Adjusted Purchase
        Price") if (i) the Buyer was able to sell at least 50% of the Series B
        shares at or above the Adjusted Purchase Price and (ii) the trading
        price in the Icelandic market remained at or above the Adjusted Purchase
        Price from the time of such resale through the end of 1999;

     -  In the event that deCODE received the incremental Adjusted Purchase
        Price proceeds from the Buyer, deCODE would also receive interest on
        such amount at a rate of 6% per annum from the closing date; and

     -  The Buyer would receive a commission of 7% of the proceeds from the sale
        of the Series B preferred stock for the placement of deCODE's stock.
        This commission would only become payable in the event that the Purchase
        Price was subsequently increased to the Adjusted Purchase Price.

     On August 8, 1999, the closing date, the Buyer advised deCODE that it had
arranged for the sale of at least 50% of the Series B shares at a price of
$15.00 per share.

     EXCHANGE OF COMMON STOCK FOR SERIES B PREFERRED STOCK

     On July 12, 1999, deCODE entered into an agreement whereby it exchanged
333,333 shares of common stock held by deCODE's chief executive officer, or CEO,
for 250,000 shares of newly issued Series B preferred stock. At this time, the
common shares were estimated to have a fair value equal to 75% of the fair value
of the Series B preferred shares. The 333,333 shares of common stock were held
in treasury and subsequently re-issued during 1999.

     REPURCHASE OF SERIES A, SERIES B AND SERIES C PREFERRED STOCK

     On August 8, 1999, deCODE repurchased the 250,000 shares of Series B
preferred stock issued to its CEO pursuant to a Resolution adopted by the Board
of Directors. The 250,000 shares of Series B preferred stock were held in
treasury and subsequently re-issued during 1999.

     On August 11, 1999, deCODE repurchased and retired 2,358,074 shares of
Series A preferred stock.

     On August 24, 1999, deCODE repurchased and holds in treasury 100,000 shares
of Series C preferred stock.

     Pursuant to the Series A and Series C preferred stock repurchase agreements
and the Board Resolution, the initial repurchase price deCODE paid for such
shares of Series A, Series B and Series C preferred stock was $7.50 per share
(the "Repurchase Price"). deCODE paid the Repurchase Price to the selling
shareholders in August 1999. However, pursuant to agreements between the
respective stockholders and deCODE on July 12, 1999, it was agreed that the
repurchase price paid for the Series A, Series B and Series C preferred stock
would be equal to the Purchase Price per share, net of any commission payable to
the Buyer, at which deCODE sold shares of its Series B preferred stock in the
August 8, 1999 offering.

     ADJUSTMENT TO ISSUANCE AND REPURCHASE PRICES

     On December 28, 1999, the conditions requiring an increase of the Purchase
Price were met, and deCODE and the Buyer agreed on an Adjusted Purchase Price of
$15.00 per share for the five million shares of Series B preferred stock sold to
the Buyer on August 8, 1999. It was also agreed that the Buyer would receive the
commission in the amount of $5,250,000, representing 7% of the total aggregate
Adjusted Purchase Price for the Series B shares.

     As of December 31, 1999, deCODE has recorded a receivable from the Buyer in
the amount of $33,143,836 representing the incremental amount due from the Buyer
with respect to the Adjusted Purchase Price of $37,500,000, less commissions and
plus accrued interest. The receivable from the Buyer was paid in February 2000.

     As a result of the Purchase Price being adjusted, on December 28, 1999,
deCODE and the Series A stockholders, deCODE's CEO and the Series C stockholder
agreed upon an adjusted repurchase price for the Series A, Series B and Series C
preferred stock of $13.95 per share, that being the Adjusted Purchase Price of
$15.00 per share less a commission of 7% of the Adjusted Purchase Price.

     The incremental repurchase price per share of $6.45, or $17,467,077 in
aggregate, was paid to the respective sellers of Series A, Series B and Series C
preferred stock in February 2000, and accordingly, is reflected in the balance
sheet at December 31, 1999 as a current liability.

     UNDESIGNATED PREFERRED STOCK

     With respect to the 7,016,666 shares of preferred stock not currently
designated as an existing series, deCODE's Board of Directors is authorized,
except as otherwise limited by Delaware law, without further action by the
stockholders:

     -  to issue shares of preferred stock in one or more series;

     -  to fix or alter the dividend rights, dividend rates, conversion rights,
        voting rights, terms of redemption (including sinking fund provisions),
        redemption price or prices, and liquidation preferences of any wholly
        unissued series of preferred stock;

     -  to designate the number of shares constituting, and the designation of,
        any series of preferred stock; and

I.   STOCKHOLDERS' EQUITY:

     COMMON STOCK

     The total authorized shares of common stock, par value $0.001, of deCODE is
48,000,000 shares. Holders of shares of common stock are entitled to one vote at
all meetings of stockholders for each share held by them. The common stock has
no preemptive rights or other rights to subscribe for additional shares, no
conversion right and no right of redemption. Subject to the rights and
preferences of the holders of any preferred stock, the holders of the common
stock are entitled to receive such dividends as, when and if declared by the
Board of Directors out of funds legally available therefor for that purpose.

     Notes receivable for the purchase of common stock are collateralized only
by the shares to which they relate, are payable after a fixed period of
generally four years and bear a fixed interest rate of generally six percent per
annum.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Of the 6,015,000 shares of common stock that were issued and paid at the
inception of deCODE, 5,789,438 were issued to the founders of deCODE subject to
certain vesting provisions ("Founder Stock"). The unvested shares of Founder
Stock are subject to repurchase by deCODE at the original issue price in the
event that a founder does not continue in employment, according to individual
terms. At December 31, 1999, 503,341 shares of the Founder Stock remained
subject to repurchase.

     Of the Founder Stock, 3,606,492 shares of common stock are entitled to
piggyback registration rights with respect to the registration of such shares
under the Securities Act. Should deCODE propose to register any shares of common
stock under the Securities Act either for deCODE's own account or for the
account of other security holders, the holders of shares having piggyback rights
are entitled to receive notice of the registration and are entitled, with some
limitation, to include their shares in the registration.

     Forfeited unvested Founder Stock and unvested common stock issued upon
early exercise of stock options totalling 359,655 shares were held in treasury
and subsequently re-issued during 1999. At December 31, 1999, 1,954,623 shares
of common stock that were issued upon early-exercise of stock options remained
unvested.

     Upon the closing of a public offering, all outstanding shares of preferred
stock will automatically convert into shares of common stock. As of December 31,
1999, the number of shares of common stock issuable upon conversion are as
follows:

Also upon the closing of a public offering, warrants to purchase shares of
Series A and Series C preferred stock will automatically convert into warrants
to purchase the same number of shares of common stock. As of December 31, 1999,
warrants to purchase 1,137,814 shares of Series A preferred stock and warrants
to purchase 972,223 shares of Series C preferred stock were outstanding. Such
stock and warrants will have the right to require deCODE to file a registration
statement under the Securities Act covering the registration of their shares at
any time after 180 days from the effective date of an initial registration
statement if the holders of 50% of such shares demand registration and the
number of shares to be registered has an aggregate public offering price of at
least $5,000,000. Such registration rights are subject to conditions and
limitations, including the right of the underwriters of an offering to limit the
number of shares of common stock which security holders may include in a
registration. Further, deCODE may defer a registration for a period of 90 days
if deCODE furnishes to the holders requesting registration a certificate signed
by the chairman of the board stating that in the good faith judgment of the
Board of Directors it would be seriously detrimental to deCODE and its
stockholders for the requested registration to be effected at that time. deCODE
is generally required to bear all of the expenses of such registrations, except
underwriting discounts and selling commissions. Registration of any of the
shares of common stock held by security holders with registration rights would
result in such shares becoming freely tradable without restriction under the
Securities Act immediately upon effectiveness of such registration.

     STOCK OPTION PLAN

     In August 1996, deCODE adopted the deCODE genetics, Inc. 1996 Equity
Incentive Plan (the "Plan"). A total of 5,000,000 options are reserved to be
granted under the terms of the Plan. The Plan provides for grants of stock
options to employees, members of the Board of Directors, consultants and other
advisors who are not

employees. Options granted to date generally vest over a period of four years,
generally have a maximum term of 10 years, contain early-exercise provisions and
allow for company-provided financing of the exercise price. As of December 31,
1999, 1,041,000 shares were available for grant under the 1996 Plan.

</TABLE>

     deCODE records deferred compensation for options granted with exercise
prices below the estimated fair value of common stock at the date on which both
the number of shares to be issued and the exercise price are fixed and
determinable. Deferred compensation is amortized and recorded as compensation
expense ratably over the vesting period of the options. Stock-based compensation
expense of $11,851, $4,773,287, and $7,311,495 was recognized in the statements
of operations during the years ended December 31, 1997, 1998 and 1999.

     Each employee option grant generally vests twenty-five percent on the first
anniversary date of an employee's commencement of employment and 1/48 of the
original grant each month thereafter for the following three years.

     All options granted to date have contained a provision for early-exercise
according to the terms of the Plan with company-provided financing of the
exercise price made available. In almost all cases, employees have taken
advantage of their right to early-exercise and to fund such exercise with a
company-provided loan. The company-provided loans are due after a fixed term of
generally four years and bear a fixed interest rate of six percent per

annum. In March 1999, deCODE amended certain previously granted options, thus
resulting in a new measurement date for such options.

OTHER STOCK OPTION ARRANGEMENTS

     In February 1998, deCODE granted a stock option to a collaborator which was
not granted under the provisions of the Plan. This option was for 80,000 shares
of common stock at an exercise price of $0.40 per share. The option had no
vesting provisions and was immediately exercised using company-provided
financing that was subsequently paid in 1999.

     PRO FORMA NET LOSS PER COMMON SHARE

     deCODE applies Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees," in accounting for options granted to employees and
has adopted the disclosure-only provisions of Statement of Financial Accounting
Standards No. 123 (SFAS No. 123), "Accounting for Stock-Based Compensation".
Accordingly, no compensation expense as calculated under SFAS No. 123 has been
recognized in the statements of operations for stock options granted to
employees.

     deCODE applies SFAS No. 123 in accounting for options granted to
non-employees and has recognized the grant date fair value of options granted to
non-employees in the statements of operations.

     Had compensation cost for all stock options been determined based on the
fair value at the grant date for awards in 1997, 1998 and 1999, consistent with
the provisions of SFAS No. 123, deCODE's net loss and basic and diluted net loss
per share would have been changed to the pro forma amounts indicated below:

     The effects of applying the provisions of SFAS No. 123 on net loss and net
loss per share as stated above is not necessarily representative of the effects
on reported income or loss for future years due to, among other things, the
vesting period of the stock options and the fair value of additional stock
options that may be granted in future years.

     The fair values of the options granted during 1997, 1998 and 1999 are
estimated on the date of grant using the Black-Scholes option-pricing model with
the following weighted-average assumptions: no dividends, expected volatility of
50%, 50% and 60%, respectively; expected terms of 3.1 years, 3.8 years and 3.9
years, respectively; and risk-free interest rates of 5.82%, 5.44% and 5.74%,
respectively.

K.   DEFINED CONTRIBUTION BENEFITS:

     deCODE contributes to relevant pension organizations for personnel in
Iceland in accordance with Icelandic law. Certain other discretionary
contributions may be made. Contributions are based on employee salaries and
deCODE has no further liability in connection with these plans. Total
contributions were $101,064, $381,138 and $747,939 for the years ended December
31, 1997, 1998 and 1999, respectively.

L.  INCOME TAXES:

     deCODE accounts for income taxes in accordance with Statement of Financial
Accounting Standards No. 109 (SFAS No. 109), "Accounting for Income Taxes." Due
to deCODE incurring net losses since inception, there is no provision for income
taxes for the years ended December 31, 1997, 1998 and 1999. deCODE has not paid
income taxes in the United States, Iceland or elsewhere since inception.

assets and deferred tax liabilities were as follows:

     At December 31, 1999, deCODE has available a net operating loss
carryforward for federal income tax purposes of approximately $38,000 to offset
future federal taxable income in the United States which expires in 2018. deCODE
also has approximately $18,829,000 of foreign net operating loss carryforwards
available to offset future taxable income in Iceland which expires in varying
amounts beginning in 2004. As required by SFAS No. 109, the management of deCODE
has evaluated the positive and negative evidence bearing upon the realizability
of its deferred tax assets and has established a full valuation allowance for
such assets, which are comprised principally of net operating loss carryforwards
and capitalization of research and development costs. Management reevaluates the
positive and negative evidence periodically. The net operating loss
carryforwards could be limited in the future if there is a significant change in
ownership.

M.  SUBSEQUENT EVENTS:

     On January 22, 2000, the Ministry of Health and Social Security granted
deCODE's Icelandic subsidiary, Islensk erfethagreining ehf., an operating
license to create and run the Icelandic Health Sector Database, or IHD. The
license, which has a term of twelve years, allows deCODE to collect data from
medical records of Icelandic healthcare institutions and self-employed
healthcare professionals and to transfer such data in encrypted form into

a centralized database. As required by the license and concurrently with the
issuance of the license, our Icelandic subsidiary entered into an agreement with
the Ministry. This agreement provides that deCODE must pay the Icelandic
government a fixed annual fee of 70 million Icelandic kronas (approximately
$1,000,000 at December 31, 1999) and an additional annual fee of 6% of its net
profit, up to a maximum of 70 million Icelandic kronas per year. The agreement
also provides that deCODE's rights to the IHD will be transferred to the
Ministry on the expiration or termination of the license.

     deCODE's preparation of the IHD is subject to technical requirements
imposed by the Icelandic Data Protection Commission in areas such as data
encryption and privacy protection. These requirements are subject to change from
time to time and may require greater technical capabilities than deCODE
currently has. Compliance with these requirements can be expensive and
time-consuming and may delay the development of the IHD and the DCDP or make
such development more expensive than anticipated. In addition, deCODE's
compliance is subject to evaluation by the agencies imposing these requirements.
deCODE cannot control the time required for this evaluation, and accordingly,
the evaluation process may lead to delay in the development of the IHD and the
DCDP.

     deCODE is subject to a very extensive indemnity clause in the agreement
with the Ministry, pursuant to which it has:

     -  agreed not to make any claim against the government if the Act or the
        license are amended as a result of the Act or rules relating to the IHD
        being found to be inconsistent with the rules of the European Economic
        Area or other international rules and agreements to which Iceland is or
        becomes a party;

     -  agreed that if the Icelandic state by a final judgment is found to be
        liable or subject to payment to any third party as a result of the
        passage of legislation on the IHD and/or issuance of the IHD license,
        deCODE will indemnify it against all damages and costs in connection
        with the litigation; and

     -  agreed to compensate any third parties with whom the Icelandic
        government negotiates a settlement of liability claims arising from the
        legislation on the IHD and/or the issue of the IHD license, provided
        that the Icelandic government demonstrates that it was justified in
        agreeing to make payments pursuant to the settlement.

     The license and the agreement under which deCODE received the license also
require it to:

     -  pay the costs incurred by the health institutions (including the costs
        of medical record software) in connection with the entering of data from
        medical records before transfer to the IHD;

     -  financially segregate the operation of the IHD from its other activities
        by maintaining a separate operating unit, and separate accounts for the
        IHD;

     -  pay the costs of the governmental agencies which monitor deCODE's IHD
        activities;

     -  indemnify and agree not to sue the Icelandic government for any
        liability resulting from the passage of the legislation on the IHD and
        its operation and/or the issuance of the IHD; and

     -  observe international science ethics rules.

     The license prohibits deCODE from, among other things:

     -  abusing its position by charging unreasonable fees, refusing business to
        our competitors or discriminating among customers by imposing
        discriminatory or other onerous business terms on our customers; or

     -  assigning or pledging our rights in the license.

     The IHD license will expire in January 2012, unless an extension is
granted.

     All expenses of registration incurred in connection herewith are being
borne by us.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 102(b)(7) of the Delaware General Corporation Law ("DGCL") enables
a corporation in its certificate of incorporation to limit the personal
liability of its directors for violations of their fiduciary duty of care.
Accordingly, Section 4.7 of our certificate of incorporation states that a
director will not be personally liable to us or to our stockholders for monetary
damages resulting from any breach of fiduciary duty as a director, except for
liability (i) for any breach of the director's duty of loyalty to us or to our
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) under Section 174 of
the DGCL, or (iv) for any transaction from which the director derived an
improper personal benefit. If the DGCL is amended, then the liability of a
director will be eliminated or limited to the fullest extent permitted by the
amended DGCL.

     Subsection (a) of Section 145 of the DGCL empowers a corporation to
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (other than an action by or in
the right of the corporation) by reason of the fact that he is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with the
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.

     Subsection (b) of Section 145 empowers a corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee, or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of that action or
suit if he acted in good faith and in a manner he reasonably believed to be in,
or not opposed to, the best

                                      II-1
<PAGE>   102

interests of the corporation. No indemnification will be made, however, in
respect to any claim, issue or matter as to which that person is adjudged to be
liable to the corporation, unless and only to the extent that the Court of
Chancery or the court in which that action or suit was brought will determine
upon application that, despite the adjudication of liability but in view of all
of the circumstances of the case, that person is fairly and reasonably entitled
to indemnity for the expenses which the Court of Chancery or such other court
deems proper.

     Section 145 further provides that to the extent a present or former
director or officer of a corporation has been successful in the defense of any
action, suit or proceeding referred to in subsections (a) and (b) of Section
145, or in defense of any claim, issue or matter therein, that person will be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him; that the indemnification provided by Section 145 will not be
deemed exclusive of any other rights to which the indemnified party may be
entitled; and that the scope of indemnification extends to directors, officers,
employees, or agents of a constituent corporation absorbed in a consolidation or
merger and persons serving in that capacity at the request of the constituent
corporation for another. The determination of whether indemnification is proper
under the circumstances, unless made by a court, is determined by (a) a majority
of the disinterested members of the Board of Directors or board committee; (b)
independent legal counsel (if a quorum of the disinterested members of the Board
of Directors or board committee is not available or if the disinterested members
of the Board of Directors or a board committee so direct); or (c) the
stockholders.

     Section 145 also empowers us to purchase and maintain insurance on behalf
of our directors or officers against any liability asserted against them or
incurred by them in any such capacity or arising out of their status as our
directors or officers whether or not we would have the power to indemnify them
against the liabilities under Section 145. We currently carry liability
insurance for the benefit of our directors and officers that provides coverage
for any damages (excluding punitive or exemplary damages, fines or penalties),
settlements, and reasonable and necessary legal fees and expenses incurred by
any of the officers or directors resulting from any judicial or administrative
proceeding initiated during the policy period against any of the officers or
directors in which they may be subjected to a binding adjudication of liability
for damages or other relief, including any appeal therefrom, for any actual or
alleged error, omission, misstatement, misleading statement, neglect, breach of
duty or negligent act by any officer or director, while acting solely in his
capacity as a director or officer of the company (or any subsidiary of the
company). Among other exclusions, our current policy specifically excludes
coverage for any claim: by or at the behest of any person or entity that at the
time the claim is first made owns or controls 20% or more of the outstanding
securities representing the present right to vote for the election of directors
of the company (and/or its subsidiaries); involving an accounting of profits
made in fact from the purchase and/or sale by the officers and directors of the
securities of the company; based upon actual or alleged pollution or
contamination; for violations of the Employee Retirement Income Security Act of
1974; by, on behalf of, or at the direction of, the company or other officers or
directors; brought about by any dishonest, fraudulent or criminal act or
omission or any personal profit or advantage gained by any director or officer
to which he was not legally entitled; based upon or arising out of a wrongful
act actually or allegedly committed subsequent to a corporate takeover; based
upon or arising out of their services as directors, officers or employees of any
entity other than the company (or a subsidiary of the company); for actual or
alleged libel, slander, defamation, bodily injury, sickness, disease, death,
false arrest, false imprisonment, assault, battery, mental anguish, emotional
distress, invasion of privacy or damage to or destruction of tangible property;
based on allegations that computer software or hardware failed to function
properly because of a Year 2000 problem; and/or based upon any future public or
private offering of securities. We expect that the exclusion for securities
offerings will be removed before the effective date of this registration
statement.

     Section 42 of our bylaws requires that we indemnify each director and
executive officer to the fullest extent allowable under the DGCL, and empowers
us to indemnify our other officers, employees and other agents. Section 42
further provides, however, that we may limit the extent of our indemnification
by individual contracts with our directors and executive officers, and further,
that we will not be required to indemnify any director or executive officer in
connection with any proceeding (or part of a proceeding) initiated by that
person or any proceeding by that person against us or our directors, officers,
employees or other agents unless (a) indemnification is expressly required to be
made by law, (b) the proceeding was authorized by our Board of Directors or (c)
indemnification is provided by us, in our sole discretion, pursuant to the
powers vested in us

                                      II-2
<PAGE>   103

under the DGCL. This provision is a contract with each director and executive
officer who serves in that capacity at any time while the provision and the
relevant provisions of the DGCL are in effect.

     Any repeal or modification of Section 42 of our bylaws will only be
prospective, and will not affect any rights in effect at the time of the alleged
occurrence of any action or omission to act that is the cause of any proceeding
against any of our agents. Further, the rights conferred on any person by
Section 42 will continue as to a person who has ceased to be a director,
officer, employee or other agent and will inure to the benefit of the heirs,
executors and administrators of such person.

     We have, in addition, entered into an indemnity agreement with one of our
directors, Sir John Vane. The agreement requires us, subject to certain
exceptions, to hold harmless and indemnify Sir John to the fullest extent
authorized or permitted by the provisions of the bylaws and the DGCL, as each
may be amended from time to time (but, only to the extent that an amendment
permits us to provide broader indemnification rights than the bylaws or the DGCL
permitted prior to adoption of that amendment). Subject to certain exclusions,
we further agreed to hold harmless and indemnify Sir John against any and all
expenses (including attorneys' fees), witness fees, damages, judgments, fines
and amounts paid in settlement and any other amounts that he becomes legally
obligated to pay because of any claim or claims made against or by him in
connection with any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, arbitrational, administrative or investigative
(including an action by or in the right of us) to which he is, was, or at any
time becomes, a party, or is threatened to be made a party, by reason of the
fact that he is, was, or at any time becomes, our director, officer, employee or
other agent, or is or was serving, or at any time serves, at our request, as a
director, officer, employee or other agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise; and otherwise
to the fullest extent as may be provided to him by us under our bylaws and the
DGCL.

     Our agreement with, and obligations to, Sir John under his indemnity
agreement will continue during the period that he serves as our director,
officer, employee or other agent (or is or was serving at our request as a
director, officer, employee or other agent of another company, partnership,
joint venture, trust, employee benefit plan or other enterprise) and will
continue thereafter so long as he will be subject to any possible claim or
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, arbitrational, administrative or investigative, by reason of the fact
that the director was serving in the capacity referred to herein.

     Further, the Underwriting Agreement, a proposed form of which is filed as
Exhibit 1.1 hereto, contains provisions for indemnification of our underwriters
and their officers, directors and certain other persons, against certain civil
liabilities, including certain liabilities under the Securities Act.

Section 4(2) and/or Regulation D as transactions not involving any public
offering or Regulation S as offers and sales that occurred outside the United
States. Where appropriate, the purchasers represented their intention to acquire
the securities for investment only and not with a view to the distribution
thereof or that they were non-U.S. persons. Appropriate legends are affixed to

received adequate information about us or had access, through employment or
other relationships, to adequate information.

     FINANCIAL STATEMENT SCHEDULES

     No schedules are required because the information is either not applicable
or is presented elsewhere herein.

ITEM 17.  UNDERTAKINGS.

     We hereby undertake to provide to the underwriter at the closing specified
in the underwriting agreement certificates in such denominations and registered
in such names as required by the underwriter to permit prompt delivery to each
purchaser.

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

     We hereby undertake that:

          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this registration statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by us pursuant to Rule 424(b)(1) or (4) or 497(h)
     under the Securities Act will be deemed to be part of this registration
     statement as of the time it was declared effective.

          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus will
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time will be
     deemed to be the initial bona fide offering thereof.
