         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 1996 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.
Company programs are focused on the use of SomatoKine(R), a novel IGF-BP3
complex, to treat destructive metabolic processes (catabolism) in acute
indications such as major surgery, organ damage/failure, and traumatic injury.
Potential chronic indications could include osteoporosis, chronic renal failure,
and wasting conditions associated with cancer and AIDS.

      The Company's development focus is on SomatoKine, the recombinant
equivalent of the naturally occurring complex formed by the anabolic hormone
insulin-like growth factor-I (IGF-I) and its major binding protein, BP3, which
shows potential as a hormone replacement therapy for patients suffering from
severe physical trauma and serious illness. The active portion of the complex is
IGF-I, an anabolic hormone known to play a key role in diverse biological
processes, including tissue repair, organ function, and muscle and bone
formation. 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: acute insulin effects (e.g.
hypoglycemia), suppression of growth hormone secretion, short circulating half
life, and limited and transient efficacy at safe dosage levels. When IGF-I is
bound to BP3, as it is in nature, it does not display these acute limitations.
Furthermore, BP3 appears to be critical in the regulation of the release of
IGF-I to target tissue sites, where the hormone is active only when needed.

      The Company completed a single-dose Phase I human clinical study in July
1996; results from the study have shown that SomatoKine safely administers IGF-I
at substantially higher dosage levels than have ever been feasible before,
increasing the peak blood concentration of IGF-I up to 35-times normal levels.
This ability to substantially enhance the


                                       7
   8
circulating reservoir of IGF-I should allow clinical evaluation of the hormone's
anabolic activities and therapeutic potential beyond what has been possible
using either free (unbound) IGF-I or growth hormone. A second multiple-dose
Phase I study was initiated to evaluate the safety and metabolic effects of a
range of dosage levels administered daily for six days. Preliminary analysis of
the results from this second Phase I study substantiates SomatoKine's safety
profile. The Company plans to begin feasibility studies later this fiscal year;
these studies are designed to identify efficacy trends in the patient
population. Clinical study targets and the design for Phase II will be based on
results from these feasibility studies that support the likelihood of treatment
success, involve short-term treatment that can respond rapidly to SomatoKine
therapy and readily yield efficacy data. The Company is manufacturing
SomatoKine, according to current Good Manufacturing Practices (GMP), at its
Santa Clara facility for the upcoming feasibility studies and future Phase II
clinical trials.

     The Company has a license agreement with The Green Cross Corporation, a
Japanese pharmaceutical company, 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. Genzyme is currently developing TGF-beta-2 for tissue repair and
the treatment of systemic indications. The Company is not currently pursuing an
in-house TGF-beta-2 program, other than as related to the Genzyme program.

      Celtrix has not earned substantial revenues from product sales and at
September 30, 1996 has an accumulated deficit of $97.8 million, which includes
non-recurring, non-cash charges of $17.3 million for acquired in-process
research and development and licensing fees. The Company expects to incur
additional operating losses, which may fluctuate 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 $6.4 million for the
three- and six-month periods ended September 30, 1996, respectively, compared to
$2.8 million and $5.4 million for the same periods in 1995. Net loss per share
were $0.23 and $0.42 for the three- and six-month periods ended September 30,
1996, respectively, compared to $0.20 and $0.39 for the same periods in 1995.

      Revenues, consisting of product sales, related party and other revenues,
decreased 73% to $37,000 for the three-month period ended September 30, 1996
from $139,000 for the same period in 1995 due primarily to Orphan Drug Grant
receipts in 1995. Revenues decreased 89% to $79,000 from $707,000 for the
six-month period ended September 30, 1996 from the same period in 1995,
primarily as a result of the sale of the Vitrogen(R)100 Collagen business to
Collagen Corporation ("Collagen") in 1995.

      Operating expenses increased 16% to $3.6 million for the three-month
period ended September 30, 1996 from $3.1 million for the same period in 1995,
due primarily to increased costs associated with Phase I human clinical studies
and increased manufacturing of SomatoKine for upcoming feasibility studies and
Phase II clinical trials. The Company expects operating expenses to increase as
it expands its clinical program and increases its SomatoKine production
activities to support Phase II clinical trials.

      Interest income, net of interest expense, decreased 8% to $135,000 for the
three-month period ended September 30, 1996 from $146,000 for the same period in
1995, and decreased 9% to $298,000 for the six-month period September 30, 1996
from $326,000 for the same period in 1995. The decreases are due to the lower
average cash, cash equivalent and short-term investment balances. Interest
expense was $24,000 and $54,000 for the three- and six-month periods ended
September 30, 1996, respectively, and $48,000 and $100,000 for the same periods
in 1995, respectively.

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 investment in Metra Biosystems, Inc. and, to a lesser
extent, other revenues and product sales.

      At September 30, 1996, Celtrix's cash, cash equivalents and short-term
investments were $11.4 million compared to $17.6 million at March 31, 1996. The
net decrease of $6.2 million was due to cash outlays consisting of $5.5 million
in net cash used in operating activities and approximately $700,000 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
1997. 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 such
products.

      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, the magnitude of these programs, progress
with preclinical and 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


                                       10

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.
