              Notes to Condensed Consolidated Financial Statements


1.  BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been
prepared by Interpore International (the "Company") without audit, pursuant to
Securities and Exchange Commission regulations. In the opinion of management,
the unaudited financial statements include all adjustments (consisting only of
normal recurring adjustments) necessary to present fairly the consolidated
financial position at June 30, 1997 and the consolidated statements of income
for the three month and six month periods ended June 30, 1997 and 1996, and the
consolidated statements of cash flows for the six month periods ended June 30,
1997 and 1996.

The accompanying consolidated financial statements include the accounts of the
Company and its subsidiaries, Interpore Orthopaedics, Inc. and Interpore Dental,
Inc., after elimination of all significant intercompany transactions.

The statements of income and cash flows for the 1997 interim periods are not
necessarily indicative of results to be expected for the full year.

These consolidated financial statements should be read in conjunction with the
financial statements included in the Company's Annual Report on Form 10-K for
the year ended December 31, 1996, as filed with the Securities and Exchange
Commission.

3.  CONTINGENCIES

In the ordinary course of its business, the Company is subject to legal
proceedings, claims and liabilities, including product liability matters. In the
opinion of management, the amount of ultimate liability with respect to any
known proceedings or claims will not materially affect the financial position or
results of operations of the Company.

4.  IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

In February 1997, FASB Statement of Financial Accounting Standards No. 128 (SFAS
128) was issued and is effective for interim and annual periods ending after
December 15, 1997. SFAS 128 requires presentation of both basic and dilutive
earnings per share. Management believes that basic and dilutive earnings per
share will not differ materially from the earnings per share amounts in the
accompanying statements of income.

5.  SALE OF ASSETS

In April 1997, the Company entered into a definitive agreement for the sale of
its dental implant business to Steri-Oss Inc. of Yorba Linda, California. In May
1997, the sale was completed, and the Company received an initial cash payment
of $1.5 million. A deferred cash payment of $749,000, subject to certain
purchase price adjustments, is due in January 1998. The transaction, including
associated costs, resulted in a net charge of $617,000.

Sales of orthopaedic products, primarily Pro Osteon(R) bone graft substitute
material for orthopaedic applications, increased in the quarter ended June 30,
1997 by $525,000 or 19.1% to $3.3 million compared to $2.8 million for the first
quarter of 1996. Domestic sales during the first quarter of 1997 through direct
sales representatives increased 54.7% while sales through distributors decreased
29.9% compared to the same quarter of 1996. Increasing direct representative
sales and declining domestic distributor sales has generally been the trend
since the Company created a domestic direct sales force and terminated
distribution agreements with certain domestic distributors that were not
achieving satisfactory market penetration. The Company continues to evaluate
distributor territories on a case-by-case basis, and will consider additional
distributor terminations with replacement by direct sales representatives in
markets where penetration is not satisfactory. International sales through
distributors increased 119.1% between the respective quarters.

Sales of the Company's OEM products, which consist mostly of porous
hydroxyapatite material for dental applications and for orbital implants,
increased by 82.9% in the quarter ended June 30, 1997 to $459,000 versus
$251,000 for the second quarter of 1996. The increase reflects product purchased
by Steri-Oss pursuant to the distribution agreement that was entered into in
connection with the sale of the Company's dental implant business to Steri-Oss.

The decline in sales of the Company's dental products (titanium dental implant
systems and Interpore 200(R) Porous Hydroxyapatite ("IP200") for dental use)
reflects the discontinuance of dental sales effective April 18, 1997. Sales of
IP200 to Steri-Oss subsequent to the sale of the dental business are now
classified as OEM product sales.

For the first six months of 1997, net sales of $8.7 million were $1.2 million or
11.8% lower than sales of $9.9 million for the same period of 1996. The
following table presents sales by category for the six month periods ended June
30:

Sales of orthopaedic products increased for the six months ended June 30, 1997
by $763,000 or 13.7% to $6.3 million compared to $5.6 million for the same
period of 1996. Domestic sales during the first half of 1997 through direct
sales representatives increased 50.6% while sales through distributors decreased
32.2% compared to the first half of 1996. International sales increased 169.0%
between the respective periods.

Sales of the Company's OEM products increased by 35.6% to $682,000 for the six
month period ended June 30, 1997 versus $503,000 for the six month period of
1996.

The decrease in sales of the Company's dental products from $3.8 million to $1.7
million, a 55.2% decrease, reflects the discontinuance of dental sales effective
April 18, 1997.

The gross margins as percentages of sales for the quarter ended June 30, 1997
improved to 81.3% from 74.0% for the quarter ended June 30, 1996. Gross margin
percentages for the six month periods ended June 30, 1997 and 1996 were 76.5%
and 72.9%, respectively. The improved gross margins reflect the discontinuance
of dental product sales which had lower gross margins than the Company's
remaining orthopaedic and OEM products.

Total operating expenses for the quarter ended June 30, 1997 decreased by 5.1%
or $189,000 as compared to the same quarter of 1996. Research and development
expenses decreased by 9.6% or $53,000, and selling and marketing expenses
decreased by 29.9% or $768,000 versus the same quarter of 1996. Selling and
marketing expenses directly related to the dental business declined by $821,000,
while selling and marketing expenses in the orthopaedic business increased by
$53,000, mostly the result of commissions on increased sales through the direct
sales force. The decreases in research and development and selling and marketing
expenses were partially offset by the $617,000 loss recorded on the sale of the
dental business

For the six month period ended June 30, 1997, total operating expenses decreased
by 5.2% or $380,000 to $6.9 million from $7.3 million for the six months ended
June 30, 1996. Research and development expenses remained relatively constant.
Selling and marketing expenses decreased by $908,000 or 18.3%. Selling and
marketing expenses directly related to the dental business declined by $974,000,
while selling and marketing expenses in the orthopaedic business increased by
$66,000, mostly the result of commissions on increased sales through the direct
sales force. General and administrative expenses decreased 5.2% as a result of
lower professional fees and other overhead expenses, partly the result of the
sale of the dental business. The decreases in operating expenses were partially
offset by the $617,000 loss recorded on the sale of the dental business.

No income tax provision was recorded during the six month periods ended June 30,
1997 and 1996 due to the anticipated utilization of the Company's net operating
loss carryforwards during the two periods.

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 1997 and December 31, 1996, cash, cash equivalents and short-term
investments totaled $12.6 million and $10.3 million, respectively. This increase
of $2.3 million was the result of the net proceeds from the sale of the dental
business and positive cash flow from operations in the first half of 1997. Total
working capital increased to $17.5 million at June 30, 1997 from $16.9 million
at December 31, 1996 and the current ratio improved from 10.4 to 14.5.

The $12.6 million total of cash, cash equivalents and short-term investments
remains available to support the Company's continued investment in the
development of its business, including the pursuit of FDA approvals for
additional indications for the use of Pro Osteon, development or acquisition of
new bone graft products or complementary products, and possible acquisitions of
businesses. Additionally, the Company has a $5 million revolving line of credit
which expires in July 1998 and which had no amount outstanding at June 30, 1997.

The Company believes it currently possesses sufficient resources to meet the
cash requirements of its operations for at least the next year.

         THIS AMENDMENT TO LOAN AGREEMENT is entered into between SILICON VALLEY

         The Parties agree to amend the Loan and Security Agreement between

follows. (Capitalized terms used but not defined in this Amendment, shall have
the meanings set forth in the Loan Agreement.)

         1. AMENDED MATURITY DATE. The Maturity Date set forth in Section 5.1 of
the Schedule to the Loan Agreement is amended effective on the date hereof, to
read as follows:

         2. FEE. Borrower shall pay to Silicon a facility fee in the amount of
0.5% of the amount of each Loan made under the Loan Agreement on or after the
date of this Amendment, until Borrower has paid Silicon an aggregate of $25,000

due and payable at the time that Silicon makes any such Loan, with the
understanding that payment of such fee shall be a condition to the making of any
such Loan. Further, such fee shall be in addition to all interest and all other
fees payable to Silicon and shall be non-refundable.
