              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1.      Condensed Consolidated Interim Financial Statements

        The condensed consolidated balance sheet as of December 31, 1997, the
condensed consolidated statements of operations for the three- and nine-month
periods ended December 31, 1997 and 1996, and the condensed consolidated
statements of cash flows for the nine-month periods ended December 31, 1997 and
1996 have been prepared by the Company, without audit. In the opinion of
management, the accompanying unaudited interim condensed consolidated financial
statements include all adjustments, which include normal recurring adjustments,
necessary to present fairly the Company's financial position, results of its
operations and its cash flows. Interim results are not necessarily indicative of
results to be expected for a full fiscal year.

        Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted. These condensed consolidated
financial statements should be read in conjunction with the audited financial
statements and notes thereto for the fiscal year ended March 31, 1997 in the
Company's 1997 Annual Report to Stockholders.

        Certain reclassifications have been made to prior year financial
statements to conform with the current year presentation.

2.      Stockholders' Equity

        In April 1997, the Company completed a private placement of 5,721,876
shares of newly issued shares of common stock at $2.438 per share, resulting in
net proceeds to the Company of $13.3 million. For every two shares of stock
issued, the Company also issued a three-year warrant to purchase an additional
share of Celtrix common stock at $2.682 per share exercisable only if the shares
of stock are held for at least one year.

        In September 1997, stockholders approved an additional 1.5 million
shares for issuance under the 1991 Stock Option Plan.

3.      Net Loss Per Share

        In February 1997, the Financial Accounting Standards Board issued
Statement No. 128, "Earnings Per Share" ("SFAS 128"), which is required to be
adopted this fiscal quarter. Although SFAS 128 simplified the current earnings
per share ("EPS") calculation by excluding common stock equivalents from the
computation of basic EPS, adoption of SFAS 128 has no impact on the Company's
computation of net loss per share in the periods ended December 31, 1997 and
1996, or in previously disclosed periods as common stock equivalents have been
excluded due to their antidilutive effect.

4.      Gain on Sale of Investment in Prograft Medical, Inc.

        The $737,000 gain on investment reported was the result of the sale of
43,750 shares of Prograft Medical, Inc. ("Prograft") preferred stock in June
1997; these shares were held by the Company since 1993.

5.      License Agreements
        In December 1997, the Company entered into a new license agreement with
Genzyme Corporation ("Genzyme") granting Genzyme a worldwide exclusive
royalty-bearing license to TGF-beta antibodies, and license and sublicense
rights to TGF-beta receptor. Under the terms of the agreement, Genzyme will
assume the licensing and royalty obligations of Celtrix related to TGF-beta
receptor.

        Additionally, under amended terms to a prior TGF-beta-2 license and
development agreement, Genzyme's territorial rights to develop and commercialize
TGF-beta-2 have been expanded to include Japan, China, Korea and Taiwan. In
exchange, Genzyme released Celtrix from certain service and royalty obligations
under the original agreement.

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

        The following discussion should be read in conjunction with the
condensed consolidated financial statements and notes thereto included in Part I
- -- Item 1 of this Quarterly Report and the financial statements and notes
thereto in the Company's 1997 Annual Report to Stockholders.

OVERVIEW

        Celtrix Pharmaceuticals, Inc. is a biopharmaceutical company developing
novel therapeutics for the treatment of seriously debilitating, degenerative
conditions primarily associated with severe trauma, chronic diseases or aging.
The Company's focus is on regenerating lost muscle, bone and other tissues
essential for the patient's health and quality of life. Ongoing product
development programs target acute traumatic injury, such as hip fracture surgery
in the elderly, and severe burns. Other potential indications include severe
osteoporosis and protein wasting diseases associated with cancer, AIDS and other
life-threatening conditions.

        The Company's development focus is on SomatoKine, a naturally occurring
complex formed by the anabolic hormone insulin-like growth factor-I (IGF-I) and
its major binding protein, BP3, which shows therapeutic potential for patients
suffering from severe physical trauma and serious illness. IGF-I, a key anabolic
hormone, is known to play a major role in diverse biological processes,
including muscle and bone formation, and tissue repair. However, IGF-I does not
naturally exist in quantity free of its binding proteins, and limitations
associated with administering free IGF-I therapeutically have proven
significant, such as acute insulin effects (e.g. hypoglycemia,
hypophosphatemia). When IGF-I is bound to BP3, as it is in nature, it does not
display these acute limitations. Results from earlier Phase I studies provided
evidence that administration of SomatoKine safely delivers IGF-I at
substantially higher dosage levels than had been feasible before with free
IGF-I, and the elevated levels of SomatoKine also appeared to stimulate bone and
connective tissue metabolism.

        Currently Phase II clinical feasibility studies are progressing in the
use of SomatoKine for hip fracture surgery in the elderly and severe burns.
Studies have shown that following hip fracture surgery, blood levels of IGF-I
drop significantly and patients begin losing lean body and bone mass rapidly.
The hip fracture study will investigate the ability of short-term treatment with
SomatoKine to build muscle and bone mass, restore mobility, and increase the
patient's

functional independence following hip fracture surgery. In the area of severe
burns, studies have shown that patients typically suffer from destructive
metabolic processes (catabolism) which causes severe nutritional inefficiency
and retards healing. SomatoKine offers potential short-term treatment by
stimulating healthy metabolic processes (anabolism) that may speed tissue
repair. The severe burns study will evaluate patients through two graft cycles
with the primary endpoint being faster healing of the donor graft site which
could shorten the length of hospitalization. Results from both the hip fracture
surgery and severe burns studies will guide the design of future clinical
trials, including a potential severe osteoporosis feasibility trial with a
corporate partner. Celtrix manufactures SomatoKine according to current Good
Manufacturing Practices (GMP) at its Santa Clara, California facility.

      The Company has a license agreement with The Green Cross Corporation, a
Japanese pharmaceutical company that recently merged with Yoshitomi
Pharmaceutical Industries Ltd., covering the development and commercialization
of SomatoKine for the treatment of osteoporosis in Japan. The Company also has a
product development, license and marketing agreement with Genzyme Corporation
("Genzyme") for TGF-beta-2, a potential pharmaceutical based on a naturally
occurring compound which appears to play an important role in regulating healthy
cell functions. In December 1997, under amended terms, the Company granted
Genzyme expanded territory rights to TGF-beta-2 to include Japan, China, Korea
and Taiwan. Additionally, under a separate license agreement, Genzyme was
granted a worldwide royalty- bearing license to TGF-beta antibodies and receptor
technology. The Company is not currently pursuing an in-house TGF-beta-2
program.

        Celtrix has not earned substantial revenues from product sales and at
December 31, 1997 has an accumulated deficit of $113.4 million. The Company
expects to incur additional operating losses, which may fluctuate from quarter
to quarter, for at least the next several years as the Company expands its
development activities, including clinical trials and manufacturing.

        There can be no assurance that Celtrix will ever achieve either
significant revenues from product sales or profitable operations. To achieve
profitable operations, the Company, alone or with others, must successfully
develop, obtain regulatory approval for and market its potential products. No
assurance can be given that the Company's product development efforts will be
successfully completed, that required regulatory approvals will be obtained, or
that any products, if developed and introduced, will be successfully marketed or
achieve market acceptance.

RESULTS OF OPERATIONS

        Celtrix incurred a net loss of $3.5 million and $9.3 million for the
three- and nine-months ended December 31, 1997, compared to $3.4 million and
$9.8 million for the same periods in 1996. Net loss per share decreased to $0.17
and $0.44 for the three- and nine-months ended December 31, 1997, from $0.22 and
$0.64 for the same periods in 1996, due primarily to an increase in shares
outstanding as a result of the April 1997 private placement.

        Revenues increased to $36,000 and $115,000 for the three- and
nine-months ended December 31, 1997 from $29,000 and $108,000 for the same
periods in 1996 due mainly to the sale of material for research purposes.

        Operating expenses increased 6% to $3.7 million for the three-months
ended December 31, 1997 from $3.5 million for the same period in 1996, and
increased 4% to $10.7 million for the nine-months ended December 31, 1997 from
$10.3 million for the same period in 1996. The increases were due primarily to
increased human clinical testing and the manufacture of SomatoKine.

        Interest income, net of interest expense, increased 47% to $148,000 for
the three-months ended December 31, 1997 from $101,000 for the same period in
1996, and increased 41% to $564,000 for the nine-months ended December 31, 1997
from $399,000 for the same period in 1996. These increases were due primarily to
the higher average cash, cash equivalent and short-term investment balances as a
result of the April 1997 private placement. Interest expense was $7,000 and
$24,000 for the three- and nine-months ended December 31, 1997, respectively,
and $19,000 and $74,000 for the same periods in 1996, respectively.

        The $737,000 gain on investment reported under nine-months ended
December 31, 1997 was the result of the sale of 43,750 shares of Prograft
preferred stock in June 1997.

LIQUIDITY AND CAPITAL RESOURCES

        Celtrix has funded its activities with proceeds from public and private
offerings, advances from Collagen, research and development revenues from
collaborative arrangements, lease and debt financing arrangements, proceeds from
liquidating its equity investments and, to a lesser extent, other revenues and
product sales.


                                       10


   11
        At December 31, 1997, Celtrix's cash, cash equivalents and short-term
investments were $10.4 million compared to $5.8 million at March 31, 1997. The
net increase of $4.6 million was due primarily to net proceeds of $13.5 million
received from the issuance of common stock, $737,000 in realized gain from the
sale of Celtrix's investment in Prograft, partly offset by cash outlays
consisting of $8.9 million in net cash and investments used in operating
activities and $691,000 used for investing and financing activities.

        The Company believes that its existing capital resources will be
adequate to satisfy its anticipated requirements through the middle of calendar
year 1998. The Company continues to pursue the possibility of securing corporate
partner arrangements that are consistent with the Company's product development
and commercialization strategies, raising additional capital by means of selling
equity or debt securities and evaluating other options including mergers and
acquisitions. The Company's future success may depend, in part, on its
relationships with third parties, their willingness to collaborate in the
development of any potential products under development, their strategic
interest in such products and, eventually, their success in marketing.

        The Company anticipates that it will expend significant capital
resources in product research and development, which is typical in the
biopharmaceutical industry. Capital resources may also be used for the
acquisition of complementary businesses, products or technologies. The Company's
future capital requirements will depend on many factors, including scientific
progress in its research and development programs, progress with clinical
trials, the cost of scaling up manufacturing and establishing facilities, the
time and costs involved in obtaining regulatory approvals, the time and costs
involved in filing, prosecuting, enforcing and defending patent claims,
competition in technological and market developments, the establishment of and
changes in collaborative relationships and the cost of commercialization
activities and arrangements. The Company anticipates that it will be required to
raise substantial additional capital over a period of several years in order to
continue its research and development programs, including clinical trials, and
to prepare for commercialization by expanding manufacturing and marketing
capabilities. No assurance can be given that such additional capital will be
available on reasonable terms or at all. The unavailability of such financing
could delay or prevent the development and marketing of the Company's potential
products.
