NEW VALUES IN BIORA
- -------------------

The two major positive highlights for Biora during 1999 have been the
results from our Research and Development and the sales increase in the
US-market. Progress in Europe, on the other hand, has been below our
expectations.

RESEARCH & DEVELOPMENT
Our Research and Development during 1999 has produced new and interesting
results. Our research on enamel matrix proteins, of which Emdogain is one,
suggests new areas of use in addition to treatment of periodontitis. The
new results also indicate potential areas of use outside of the oral
cavity.

USA
Approximately 170,000 patients have been treated with Emdogain. The market
in the USA is the most important for Biora and during 1999 sales increased
by 89 percent compared to 1998. Many American specialists now support
treatment with Emdogain, which has resulted in a large number of new
publications during 1999. During 2000 we will continue our efforts in the
US-market and intend to launch our new product, Emdogain(R)Gel, during the
year.

EUROPE
Sales development in Europe during 1999 was lower than our expectations,
particularly in the German market. The stagnation in Germany was mainly
because of a lack of focus on customer development. As a result we have
reorganized the management of the German subsidiary and at the same time
restructured the marketing organization in Europe.

The largest markets in Europe, Germany and Italy, still have the highest
priority. We now have a European marketing organization that coordinates
sales and marketing activities with our organization in the USA. I expect
that the launch of Emdogain(R)Gel will increase the pace of our
market-penetration in Europe as well as the USA.

BIORA.COM
Our homepage "biora.com" will play a significant role in our future sales
and marketing activities. The upgrading that is now taking place will
enable us to cultivate new, larger customer groups as well as patients in a
cost-effective manner.

IMPORTANT PROGRESS IN RESEARCH AND DEVELOPMENT
During 1999 several of Biora's research-projects have yielded positive
results quickly. The Research and Development has been expanded and now
includes projects for development of products for wound healing, local hard
tissue formation and dry mouth (xerostomia), among others.

Clinical studies are ongoing for new dental indications for Biora's
principal product, Emdogain. These indications include increased treatment
of periodontitis, treatment of recession type defects, evulsed teeth,
periodontitis in connection with impacted wisdom teeth, and wound healing.

WOUND HEALING
The use of Emdogain is accompanied by perceptibly improved healing
following surgery. This effect occurs because the growth of certain
disease-causing bacteria is inhibited by direct contact with Emdogain, and
body cells in the presence of Emdogain increase the amount of growth
factors that promote healing. These characteristics open the possibility of
using Emdogain for the treatment of wounds outside the oral cavity, for
example chronic wounds and wounds from radiation treatment. Clinical pilot
studies are to begin in Scandinavia.

LOCAL BONE FORMATION
Biora has found in new pilot studies that certain enamel matrix proteins
stimulate local formation of new bone, even in and outside the oral cavity.
The continuing work is intended document the effect and to determine future
areas for indications. Biora is a part of a cooperation-project together
with four European universities which are applying for financing within the
European commissions fifth program.

DRY MOUTH (XEROSTOMIA)
As a further step in Biora's concentration on diseases of the oral cavity,
Biora has acquired the patent rights for a new method of treating dry mouth
(xerostomia). A normal flow of saliva plays a decisive role in the health
of the mouth, and therefore in the individual's well being. A greatly
reduced flow of saliva is accompanied by difficulty in swallowing and
speaking and causes great discomfort. In addition, dry mouth increases the
risk for various diseases in the oral cavity, such as caries and infections
in the mucous membrane.

Just as periodontitis, dry mouth is a secret, very common disease that
primarily affects a large number of the older population. Dry mouth is
estimated to affect approximately 15 percent of 50 year olds and
approximately 40 percent of those over 80. Dry mouth is also a common side
effect of many medicines and radiation treatment.

The acquired process is based on local application of a
cholinesterase-inhibitor, physiostagmin, that stimulates the production of
saliva from the thousands of small salivary glands in the oral mucous
membrane. Two Swedish professors from Gothenburg University, Jorgen Ekstrom
and Herbert Helander, developed the method.

Preliminary clinical studies on healthy volunteers as well as patients with
dry mouth have shown good results. The remaining work is to develop a final
formulation and clinical studies.

NEW SUBSIDIARY ESTABLISHED
To emphasize Biora AB's focus on the diseases in the oral cavity but at the
same time develop other indications, a new subsidiary, Biora BioEx AB, has
been formed. Biora BioEx, together with other partners, will continue
Biora's development of products for indications outside the oral cavity.
During 1999 Biora BioEx submitted documentation for new patents for
products for treatment in and outside of the oral cavity.

BIORA'S PRINCIPLE PRODUCT EMDOGAIN
- ----------------------------------
NEW KNOWLEDGE ABOUT EMDOGAIN AND ITS MECHANISM OF ACTION
During 1999 Biora presented new findings on Emdogain's mechanism of action.
According to these findings PDL-cells from the area between the dental root
and the jawbone (cells that are important for successful treatment) are
favored by growing in the presence of Emdogain, while the growth of
epithelial cells from the gingival margin (cells that can jeopardize the
treatment) is inhibited. This data is important for the understanding of
the product's function and for continued market penetration.

CONTINUED PROGRESS IN THE U.S. MARKET
North America is the most important and fastest growing market for Biora.
There are estimated to be approximately 4,000 periodontists in the United
States. Of those 2,550 had bought Emdogain at the end of the period. More
than half of them had bought Emdogain more than once.

Biora believes that the acceptance of Emdogain is growing in the United
States. During this year's AAP conference (American Academy of
Periodontology, the leading organization for periodontology) at the end of
September 1999, a number of periodontal opinion-leaders presented positive
results from their clinical experiences with the product. Approximately
6,000 periodontists and dentists from all over the world attended the
conference. In addition, several American specialists published articles
that confirmed Emdogain's positive effect in the surgical treatment of
periodontal disease.

EMDOGAIN APPROVED IN THE USA FOR NEW INDICATION
During 1999 the United States Food and Drug Administration (FDA) approved
Emdogain for use as an adjunct to minimally invasive surgery. This
indicates that Emdogain can be utilized in conjunction with routine scaling
and root planing procedures in the "aesthetic zone", which include the
teeth and gums which appear when a person smiles.

Biora estimates that the target group in the United States for the new area
of application is about 60,000 dentists. Approximately 17 million scaling
and root planing procedures are performed annually in the USA and Biora
estimates that half of those are in the aesthetic zone. An introduction is
expected during 2001.

BIORA'S AMERICAN SUBSIDIARY WON "1999 SWEDISH TRADE COUNCIL
NORTH AMERICA ANNUAL ACHIEVEMENT AWARD"
Biora, Inc., the North American subsidiary of Biora AB, was chosen as the
Swedish subsidiary of the year in the North American market. The Nominating
Committee made the following statement: "The company's successful strategy
has been to focus on clinical trials, education and the opinion leaders
within the periodontal profession."

INCREASED USAGE IN EUROPE AND JAPAN
In Germany approximately 6,900 customers had purchased Emdogain by the end
of 1999, and more than half of those had made more than one purchase.
Approximately 640 customers in Sweden had purchased Emdogain and of those
460 had made more than one purchase.

In Japan Biora's products are marketed through the Japanese biotech company
Seikagaku Corporation. According to Seikagaku, the number of customers was
slightly more than 1,100 at the end of the period, and 500 of those had
bought Emdogain more than once. During the third quarter of 1999 Seikagaku
had broadened the target group from 1,500 to 4,000 specialists and general
practitioners.

PRE-MIXED PRODUCT WILL BE LAUNCHED IN EUROPE DURING FIRST HALF OF 2000
Today Emdogain is delivered as two components, which the dentist mixes. To
simplify use Biora is developing a pre-mixed product, Emdogain(R) Gel.
Documentation for licensing the product in Europe has been submitted, and
Biora is now preparing for a launch of the product in Europe during first
half of year 2000. Documentation for licensing the product in the United
States is planned to be submitted during the first quarter of 2000

NET SALES
The Group's net sales during 1999 increased to SEK 73.6 million (1998: SEK
50.1 million). The increase is primarily attributable to increased sales in
the U.S. market. Sales growth in the German market has been unsatisfactory,
and top management of the German subsidiary has therefore been changed.

PROFIT/LOSS
Gross profit amounted to SEK 58.1 million (1998: SEK 39.3 million). The
improvement can be explained mainly by the increase in sales.

The operating loss amounted to loss of SEK 91.8 million (1998: loss SEK
71.5 million). Operating loss during the same period in 1998 includes
nonrecurring revenue from Biora's Japanese partner in an amount of SEK 39.4
million. (Operating loss for 1998 excluding the nonrecurring revenue was
SEK 110.9 million). Net financial items were SEK 5.2 million (1998: SEK
11.6 million). The decrease is explained by decreased interest bearing
assets and lower market interest rates.

Net loss after tax during the period amounted to SEK 86.7 million (1998:
loss SEK 60.0 million), corresponding to a loss per share of SEK 4.09
(1998: loss SEK 2.83) based on the average of number of shares outstanding.
(Net loss after tax during 1998 excluding nonrecurring revenue was SEK 99.4
million, corresponding to a loss per share of SEK 4.69).

Increased internal efficiency has led to lower costs of administration and
stable sales costs, while sales increased by 47%. R&D costs have increased
by SEK 2.2 million (7%) after deduction for accelerated depreciation of
capitalized R&D and the costs during 1998 relating to the registration of
Emdogain in the USA (SEK 6.3 million).

INVESTMENTS
Capital expenditures during 1999 totaled SEK 4.3 million (1998: SEK 5.8
million).

FINANCIAL POSITION
Net change in cash and cash equivalents during the period was negative, in
an amount of SEK 74.2 million (1998: negative SEK 99.3 million). At the end
of the report period the Group's liquid funds amounted to SEK 112.8 million
(1998: SEK 187.0 million), the equity/assets ratio was 78.3 percent (1998:
86.6 percent) and Group equity amounted to SEK 127.4 million (1998: SEK
214.0 million).

EMPLOYEES
As of December 31, 1999, Biora had 92 employees as compared to 85 employees
as of December 31, 1998.

PARENT COMPANY
Net sales for 1999 amounted to SEK 51.1 million (1998: SEK 36.1 million)
and its loss before appropriations and income taxes was SEK 79.4 million
(1998: loss SEK 103.0 million). The loss for 1998 includes nonrecurring
revenue of SEK 39.4 million from the Japanese distributor (The loss
exclusive of nonrecurring revenue was SEK 142.4 million).

Investments in fixed assets and patents were SEK 2.6 million (1998: SEK 3.6
million). Net change in cash and cash equivalents during 1999 was negative,
in an amount of SEK 77.9 million (1998: neg. SEK 100.3 million). At the end
of the reporting period the parent company's liquid assets amounted to SEK
103.6 million (1998: SEK 181.5 million), equity/assets ratio was 85.8%
(1998: 91.4%), and share holders' equity was SEK 145.4 million (1998: SEK
223.2 million).

DIVIDEND
The company does not have any non-restricted retained earnings therefore no
dividends shall be declared. The Board of Directors proposes that the
accumulated loss on the balance sheet, SEK 77.8 million, be covered by
charging the share premium reserve.

          1) Return on capital employed and return on equity have been
          adjusted for the effect of the nonrecurring revenue from
          Seikagaku.
          2) R&D-costs are shown gross, including capitalized costs. During
          1999, as well as during 1998, no costs have been capitalized
          under the caption Capitalized R&D costs, which explains why the
          net and gross costs were equal, 41,597. (2.5% royalty to Astra on
          sales of Emdogain has been reclassified to costs of goods sold.)
          3) Operating loss plus financial income divided by average total
          assets (total assets less non-interest-bearing operating
          liabilities including deferred taxes).
          4) Net loss divided by average equity.
          5) Shareholders' equity divided by total assets.
          6) Interest-bearing liabilities less cash and bank deposits
          divided by shareholders' equity.
          7) The number of ordinary shares outstanding used in
          determination of loss and equity per ordinary share is calculated
          on a proforma basis by giving effect to a 25:1 share split and
          the 3:1 stock dividend completed by the Company during 1996. The
          dilution effects of outstanding convertible loans and options
          have not been considered when calculating equity and loss per
          share for the years 1995-1999 as this would reduce the loss per
          share.
