3.  CONTINGENCIES

The nature of the Company's business subjects it to products liability and
related claims from time to time.


                                       6
<PAGE>   7

The Company's subsidiary, Cross Medical Products, Inc. ("Cross") and other
spinal implant manufacturers were named as defendants in various purported class
action products liability lawsuits alleging that the plaintiffs were injured by
spinal implants supplied by Cross and others. All such lawsuits were
consolidated for pretrial proceedings in the Federal District Court for the
Eastern District of Pennsylvania and, on February 22, 1995, class certification
was denied. The federal court lawsuits will remain coordinated for further
pretrial purposes, but are individual lawsuits. In response to the denial of
class certification, a large number of additional individual lawsuits have been
filed alleging, in addition to damages from spinal implants, a conspiracy among
manufacturers, physicians and other spinal implant industry members to market
products without the proper regulatory approvals. Cross has been named as a
defendant, among others, in over 750 such lawsuits. None of these cases involve
products manufactured by Cross. Cross cannot estimate precisely at this time the
number of such lawsuits that may eventually be filed. Most of the lawsuits are
pending in federal courts and are in preliminary stages. Discovery proceedings,
including the taking of depositions, have commenced in certain of the lawsuits.
Plaintiffs in these cases typically seek relief in the form of monetary damages,
often in unspecified amounts. While the aggregate monetary damages eventually
sought in all of such individual actions is substantial and exceeds the limits
of the Company's products liability insurance policies, the Company believes
that it has affirmative defenses, including, without limitation, preemption, and
that these individual lawsuits are otherwise without merit.

In addition, Cross has eight pending cases claiming products liability for
allegedly defective products manufactured by Cross.

The class action lawsuits and the individual products liability cases are being
defended by the Company's insurance carrier, in some cases under a reservation
of rights. The Company maintains claims made products liability insurance
policies with at least $5 million of coverage both per occurrence and in the
aggregate. The Company believes that it has adequate insurance for its business,
however, there can be no assurance that the $5 million per policy year limit of
coverage will be sufficient to cover the cost of defending all lawsuits or the
payment of any amounts that may be paid in satisfaction of any settlements or
judgments. Further, there can be no assurance that the Company will continue to
be able to obtain sufficient amounts of products liability insurance coverage at
commercially reasonable premiums. Future operating results could be materially
adversely affected by the formal resolution of pending cases or future claims,
whether or not such cases or claims are covered by insurance.

In addition to the above, in the ordinary course of business, the Company has
been named as a defendant in various other legal proceedings. The Company has
denied liability in all such lawsuits and is vigorously defending the same.

4.  LONG-TERM DEBT

Long-term debt at June 30, 1998 consists of $4,983,000 of Convertible
Subordinated Debentures (the "Debentures") at 8.5% due June 1, 2003. The
Debentures are convertible at any time before maturity, unless previously
redeemed, into shares of the Company's common stock at a conversion price of
$6.37 per share (the "Conversion Price)". Pursuant to the terms of the
underlying indenture, upon the merger of Cross with the Company, Debenture
holders were allowed to request redemption until June 26, 1998 at 101% of the
principal amount thereof, plus accrued interest. Requests for redemption
totaling $1.7 million were made, and redemption took place in July 1998.
Beginning July 1, 1999, the Company will be obligated to redeem the Debentures
tendered by June 1, 1999 or June 1 of any succeeding year at 100% of the
principal amount thereof plus accrued interest, subject to an annual limitation
of $25,000 per holder and an annual aggregate limitation of $262,500. During the
first six months of 1998, $97,000 of Debentures were converted into 15,221
shares of the Company's common stock.

5.  BUSINESS COMBINATION

In February 1998, the Company entered into an agreement to merge with Cross
Medical Products, Inc. ("Cross"), a publicly traded Ohio-based worldwide
supplier of spinal implant systems used to treat degenerative conditions and
deformities of the spine. The merger was approved by the shareholders of both
companies on May 6, 1998 and became effective on May 7, 1998. Approximately 6.7
million shares of the Company's common stock were issued in exchange for all of
the common stock of Cross. The merger has been accounted for as a pooling of
interests. During the second quarter, the Company recorded merger-related
expenses and restructuring charges of $3.0 million and $1.5 million,
respectively. The merger-related expenses include legal, accounting and
administrative costs incurred in connection with the merger of the Company and
Cross. The restructuring charges are associated with the planned closing of the
Dublin, Ohio facility and include severance benefits for employees not remaining
with the Company, the write-off of fixed assets not being transferred to the
Company's Irvine, California headquarters, and the accrual of remaining lease
payments for the Dublin facility.

In February 1998, the Board of Directors of the Company approved a proposal for
the Company to reincorporate from California to Delaware. The proposed
reincorporation was approved by the Company's shareholders and was completed on
May 6, 1998. In connection with the reincorporation, the Company's name was
changed from Interpore International to Interpore International, Inc.


6.  SALE OF ASSETS

In April 1997, the Company entered into a definitive agreement for the sale of
its dental implant business. 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 was received in March 1998. The transaction, including
associated costs, resulted in a net charge of $617,000 in the second quarter of
1997.


7.  SALE OF RECOVERY PRODUCTS SEGMENT

On March 12, 1997, Cross Medical Products, Inc. entered into an agreement to
sell its recovery products segment for approximately $8.2 million in cash and
the assumption of approximately $5.0 million of debt and other liabilities. The
buyer also acquired 38,250 shares of the Company's common stock for $242,000.

companies on May 6, 1998 and became effective on May 7, 1998. Approximately 6.7
million shares of the Company's common stock were exchanged for all of the
common stock of Cross. The merger has been accounted for as a pooling of
interests.

In February 1998, the Board of Directors of the Company approved a proposal for
the Company to reincorporate from California to Delaware. The proposed
reincorporation was approved by the Company's shareholders and was completed on
May 6, 1998. In connection with the reincorporation, the Company's name was
changed from Interpore International to Interpore International, Inc.

In April 1997, the Company entered into a definitive agreement for the sale of
its dental 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 was received in March 1998. As part
of the transaction, the Company and Steri-Oss negotiated a distribution
agreement whereby the Company manufactures and provides Interpore 200(R) Porous
Hydroxyapatite Bone Void Filler ("Interpore 200") for distribution by Steri-Oss
in the dental market. The transaction, including associated costs, resulted in a
net charge of $617,000 which was recorded in the quarter ended June 30, 1997.

On March 12, 1997, Cross entered into an agreement to sell its recovery products
segment for approximately $8.2 million in cash and the assumption of
approximately $5.0 million of debt and other liabilities. The buyer also
acquired 38,250 shares of the Company's common stock for $242,000.

Sales of bone biologics products, which include Pro Osteon(R) bone graft
substitute material, OEM orbital implants and OEM bone graft products for the
dental marketplace, decreased in the quarter ended June 30, 1998 by $397,000 or
10.6% to $3.3 million compared to $3.7 million for the second quarter of 1997.
This decrease is attributable primarily to a $343,000 decrease in OEM product
sales and a $167,000 return from a domestic dealer that was converted to an
agent relationship during the second quarter of 1998. Sales of spinal implant
products increased in the quarter ended June 30, 1998 by $1.0 million or 31.6%
to $4.0 million compared to $3.0 million for the second quarter of 1997,
primarily due to increasing market penetration of the Synergy(TM) Spinal Implant
System.

Domestic sales of bone biologics and spinal products were approximately $5.4
million for both quarters ended June 30, 1998 and 1997. International sales
increased $583,000 or 43.3% to $1.9 million in the second quarter of 1998
compared with $1.3 million for the same quarter of 1997.

There were no dental product sales in the quarter ended June 30, 1998,
reflecting the Company's 1997 sale of its dental business.

The gross margins as percentages of sales for the quarters ended June 30, 1998
and 1997 were 69.8% and 76.0%, respectively. The decrease primarily reflects the
comparatively higher percentage of spinal implant product sales in the 1998
period which have a lower gross margin than bone biologics products.
Additionally, less favorable purchase price and overhead absorption variances
associated with lower purchase volumes of spinal implant products in the 1998
period contributed to the decreased gross margin.

Total operating expenses for the quarter ended June 30, 1998 increased by $4.1
million as compared to the same quarter of 1997 due to the $4.5 million of
merger-related and restructuring charges. Excluding these charges and the 1997
loss on the sale of the dental business, operating expenses increased by
$272,000 or 6%. Research and development expenses increased by 27.1% or $203,000
due to increased development efforts related to the Company's spinal implant
products. Selling and marketing expenses increased $140,000 or 5.0% compared to
the second quarter of 1997 due to increased commissions to independent agents,
offset partially by the elimination of selling and marketing expenses directly
related to the dental business. General and administrative expenses decreased by
6.1%, mostly the result of cost reductions following the sale of the dental
business.

The $119,000 decrease in net interest and other income primarily relates to the
write-off of unamortized convertible debenture issuance costs associated with
the request by certain holders to redeem $1.7 million of debentures. The holders
of the debentures were entitled to redeem the debentures as a result of the
change in control of Cross resulting from the merger of the Company and Cross.

No income tax provision was recorded during the second quarter of 1998 due to
the anticipated utilization of the Company's net operating loss carryforwards
during the period.

Six months ended June 30, 1998 and 1997
- ---------------------------------------

For the six months ended June 30, 1998, net sales of $14.7 million were $172,000
or 1.2% greater than sales of $14.5 million for the same period of 1997.

Sales of bone biologics products remained relatively level at $7.0 million in
the six months ended June 30, 1998 and 1997. Sales of spinal implant products
increased in the six months ended June 30, 1998 by $1.8 million or 31.8% to $7.7
million compared to $5.8 million for the six months ended June 30, 1997,
primarily due to increasing market penetration of the Synergy Spinal Implant
System.

Domestic sales of bone biologics and spinal products increased by 10% or $1.0
million to $10.7 million for the six months ended June 30, 1998 compared to $9.7
million for the same quarter of 1997. International sales increased by $890,000
or 28.9% to $4.0 million for the six month period ended June 30, 1998 from $3.1
million for the same period of 1997.

There were no dental product sales in the six month period ended June 30, 1998,
reflecting the Company's 1997 sale of its dental business.

The gross margins as percentages of sales for the six month periods ended June
30, 1998 and 1997 were 72.5% and 72.3%, respectively.

Total operating expenses for the six months ended June 30, 1998 increased by
$3.6 million as compared to the same period of 1997 due to the $4.5 million of
merger-related expenses and restructuring charges. Excluding these charges and
the 1997 loss on the sale of the dental business, operating expenses increased
by $327,000 or 3%. Research and development expenses increased by 21.7% or
$323,000 related to increased spinal product development efforts. Selling and
marketing expenses decreased $258,000 or 4.3% compared to the six months ended
June 30, 1997 due mostly to the elimination of selling and marketing expenses
directly related to the dental business partially offset by increased
commissions to independent agents. General and administrative expenses decreased
by $392,000 or 15.6%, primarily the result of cost reductions following the sale
of the dental business.

<PAGE>   12


The $74,000 or 20.0% increase in interest income resulted from higher cash and
investment balances. The increase in interest expense of 24.9% or $78,000
resulted primarily from the write-off of unamortized convertible debenture
issuance costs.

Limited income tax provisions were recorded during the six month periods ended
June 30, 1998 and 1997 due to the anticipated utilization of the Company's net
operating loss carryforwards during the periods.


LIQUIDITY AND CAPITAL RESOURCES

At June 30, 1998 and December 31, 1997, cash, cash equivalents and short-term
investments totaled $13.2 million and $16.6 million, respectively. Total working
capital decreased to $29.2 million from $31.7 million and the current ratio
decreased to 6.8 from 7.7 at June 30, 1998 and December 31, 1997, respectively.
The decrease in cash, cash equivalents and short-term investments of $3.4
million was primarily the result of the payment of $3.3 million in
merger-related expenses and restructuring charges.

The $13.2 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 regulatory approvals for
additional indications for the use of Pro Osteon, development or acquisition of
new bone biologic and spinal implant products, and possible acquisitions of
businesses. In addition, the Company expended approximately $1.7 million in July
1998 for the redemption of convertible debentures, and will spend additional
cash in the next several quarters for remaining merger-related expenses and
restructuring activities. The Company has a $5 million revolving line of credit
which expires in July 1999 and which had no amount outstanding at June 30, 1998.

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

PART II -         OTHER INFORMATION


ITEM 1.           LEGAL PROCEEDINGS

The nature of the Company's business subjects it to products liability and
related claims from time to time.

The Company's subsidiary, Cross Medical Products, Inc. ("Cross") and other
spinal implant manufacturers were named as defendants in various purported class
action products liability lawsuits alleging that the plaintiffs were injured by
spinal implants supplied by Cross and others. All such lawsuits were
consolidated for pretrial proceedings in the Federal District Court for the
Eastern District of Pennsylvania and, on February 22, 1995, class certification
was denied. The federal court lawsuits will remain coordinated for further
pretrial purposes, but are individual lawsuits. In response to the denial of
class certification, a large number of additional individual lawsuits have been
filed alleging, in addition to damages from spinal implants, a conspiracy among
manufacturers, physicians and other spinal implant industry members to market
products without the proper regulatory approvals. Cross has been named as a
defendant, among others, in over 750 such lawsuits. None of these cases involve
products manufactured by Cross. Cross cannot estimate precisely at this time the
number of such lawsuits that may eventually be filed. Most of the lawsuits are
pending in federal courts and are in preliminary stages. Discovery proceedings,
including the taking of depositions, have commenced in certain of the lawsuits.
Plaintiffs in these cases typically seek relief in the form of monetary damages,
often in unspecified amounts. While the aggregate monetary damages eventually
sought in all of such individual actions is substantial and exceeds the limits
of the Company's products liability insurance policies, the Company believes
that it has affirmative defenses, including, without limitation, preemption, and
that these individual lawsuits are otherwise without merit.

In addition, Cross has eight pending cases claiming products liability for
allegedly defective products manufactured by Cross.

The class action lawsuits and the individual products liability cases are being
defended by the Company's insurance carrier, in some cases under a reservation
of rights. The Company maintains claims made products liability insurance
policies with at least $5 million of coverage both per occurrence and in the
aggregate. The Company believes that it has adequate insurance for its business,
however, there can be no assurance that the $5 million per policy year limit of
coverage will be sufficient to cover the cost of defending all lawsuits or the
payment of any amounts that may be paid in satisfaction of any settlements or
judgments. Further, there can be no assurance that the Company will continue to
be able to obtain sufficient amounts of products liability insurance coverage at
commercially reasonable premiums. Future operating results could be materially
adversely affected by the formal resolution of pending cases or future claims,
whether or not such cases or claims are covered by insurance.

In addition to the above, in the ordinary course of business, the Company has
been named as a defendant in various other legal proceedings. The Company has
denied liability in all such lawsuits and is vigorously defending the same.

ITEM 4.           SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

                  On May 6, 1998, the Company held its 1998 Annual Meeting of
                  Shareholders to vote on three proposals. The number of shares
                  entitled to vote was 7,110,898 of the Company's Common Stock
                  and 32,906 shares of the Company's Series E Preferred Stock.
                  The number of shares represented in person or proxy was
                  6,569,339 shares of common stock and 21,336 shares of Series E
                  Preferred Stock. The Preferred Stock voted on an as-converted
                  basis on all matters other than the reincorporation. All
                  voting information is expressed on an as-converted or
                  common-equivalent basis.

                  The following are the voting results of the three proposals:

                  Approval of the change of the Company's state of incorporation
                  from California to Delaware:

DATED:            AUGUST 11, 1998


         THIS AMENDMENT TO LOAN AGREEMENT is entered into between SILICON VALLEY
BANK ("Silicon") and the borrowers named above (jointly and severally, the
"Borrower"). Interpore International, Inc., a Delaware corporation, is the
surviving entity of the merger of Interpore International, the prior borrower

International, Inc., a Delaware corporation. Further, Cross Medical Products,
Inc. was added as a borrower pursuant to an assumption agreement executed by
such entity in favor of Silicon Valley Bank.

         The Parties agree to amend the Loan and Security Agreement between
them, dated October 24, 1990 (as amended from time to time, the "Loan
Agreement"), as follows. (Capitalized terms used but not defined in this

         or in the future delivered to Silicon have been, and will be, prepared

         in the future will completely and accurately reflect the financial
         condition of the Borrower, at the times and for the periods therein
         stated. Since the last date covered by any such statement, there has
         been no material adverse change in the financial condition or business
         of the Borrower. The Borrower is now and will continue to be solvent.
         The Borrower will provide Silicon: (i) within 10

         and, for each quarter in which any Loans have been outstanding, a
         Compliance Certificate signed by the Chief Financial Officer of the
         Borrower, certifying that throughout such period the Borrower was in
         full compliance with all of the terms and conditions of this Agreement,
         and setting forth calculations showing compliance with the financial
         covenants set forth on the Schedule and such other information as
         Silicon shall reasonably request; (ii) within 10 days after the earlier

         the Securities and Exchange Commission, such 10-K report, and, if any
         Loans have been outstanding during the quarter period then ending, a

         Officer of the Borrower, certifying that throughout such period the
         Borrower was in full compliance with all of the terms and conditions of
         this Agreement, and setting forth calculations showing compliance with
         the financial covenants set forth on the Schedule and such other
         information as Silicon shall reasonably request; and (iii) within 90
         days following the end of the Borrower's fiscal year, complete annual
         financial statements, certified by independent certified public
         accountants acceptable to Silicon."

         2. ASSUMPTION. Interpore International, Inc., a Delaware corporation,
as successor by merger to Interpore International, a California corporation,
hereby assumes and agrees to pay and perform when due all present and future
indebtedness, liabilities and obligations arising out of the Loan Agreement, the

         3. CONDITIONS PRECEDENT TO LINE UTILIZATION. Without limitation of the
terms and conditions of the Loan Agreement regarding the making of Loans, the
following represent specific and additional conditions that are to be satisfied
prior to the making of any Loans hereunder or the issuance of any letters of

necessary or desirable in order to effectuate the purposes of the Loan Agreement
(the types of documentation referred to in (A), (B) and (C) above are

Documentation"); and (II) Borrower agrees to cause any and all of its
subsidiaries and affiliates, now existing and hereafter arising (including,
without limitation, Interpore Cross International, Inc.), to execute and deliver

May 8, 1998, is entered into by and between, INTERPORE INTERNATIONAL, INC., a

THIRD BANK, a banking corporation duly organized and existing under the laws of
the State of Ohio, as trustee (the "Trustee") and supplements and amends the
Indenture, dated as of May 15, 1996, by and between Cross and the Trustee (the
"Indenture").

                                   WITNESSETH:

         WHEREAS, pursuant to the Indenture, Cross has issued $5,000,000 of 8.5%
Convertible Subordinated Debentures due 2003 (the "Debentures"); and

         WHEREAS, Section 5.09 of the Indenture provides that in the event of
any statutory exchange of securities with another corporation (including any
exchange effected in connection with a merger of a third corporation into
Cross), the holder of each Debenture then outstanding shall have the right
thereafter to convert such Debenture into the kind and amount of securities,
cash or other property which he would have owned or have been entitled to
receive immediately after such consolidation, merger, statutory exchange, sale
or conveyance had such Debenture been converted immediately prior to the
effective date of such consolidation, merger, statutory exchange, sale or
conveyance and that if necessary, appropriate adjustment shall be made to the
application of the provisions of Article Five of the Indenture with respect to
the rights and interests thereafter of the holders of the Debentures, to the end
that the provisions of Article Five of the Indenture shall thereafter
correspondingly be made applicable, as nearly as may reasonably be, in relation
to any shares of stock or other securities or property thereafter deliverable on
the conversion of the Debentures and that any such adjustment shall be made and
set forth in a supplemental indenture executed by Cross and the Trustee;

         WHEREAS, Section 12.01(b) of the Indenture provides that the Indenture
may be amended without the consent of the holders of the Debentures to make
provision with respect to the conversion rights of the holders of the Debentures
pursuant to Section 5.09 of the Indenture;

         WHEREAS, a wholly owned subsidiary of Interpore ("Merger Sub"), has
merged (the "Merger") effective as of May 7, 1998 with and into Cross pursuant
to an Agreement and Plan of Merger, dated February 11, 1998, by and among
Interpore International, a California corporation and the predecessor to
Interpore, Cross and Merger Sub (the "Merger Agreement"); and

         WHEREAS, pursuant to the Merger Agreement, (i) Cross became a wholly
owned subsidiary of Interpore and (ii) each issued and outstanding share of
common stock of Cross was converted into the right to receive 1.275 shares of
common stock of Interpore;

         NOW, THEREFORE, the parties hereto agree to amend the Indenture as
follows:

         Section 1. Shares Receivable Upon Conversion.

                  (a) Cross and Interpore hereby agree that the registered
holder of each Debenture shall have the right, subject to the provisions of
Article 5 of the Indenture, to convert the principal amount of any such
Debenture, or any portion of such principal amount which is $1,000 or an
integral multiple thereof, into that number of fully paid and nonassessable
shares of common stock of Interpore, par value $.01 per share, (calculated as to
each conversion to the nearest 1/100th of a share) obtained by dividing the
principal amount of the Debenture or portion thereof to be converted by the
Conversion Price (as defined in the Indenture) and multiplying the resulting
number of shares by 1.275.

                  (b) The activities specified in Section 5.04 of the Indenture
as requiring an adjustment to the Conversion Price if taken with respect to the
common stock of Cross shall hereafter be deemed to require a corresponding
adjustment to the Conversion Price if taken with respect to the common stock of
Interpore.

                  (c) The Debentures shall no longer be convertible into shares
of the common stock of Cross.

         Section 2. Execution in Several Counterparts. This Supplemental
Indenture may be executed in any number of counterparts, each of which shall for
all purposes be deemed to be an original and all such counterparts shall
together constitute but one and the same instrument.

         Section 3. Governing Law. This Supplemental Indenture shall be governed
by and construed in accordance with the laws of the State of Delaware applicable
to contracts made and performed in the State of Delaware.

         Section 4. Incorporation By Reference. The parties hereto agree that
the amendments contained in this Supplemental Indenture shall be incorporated by
this reference thereto into the Indenture, which Indenture as so amended shall
serve as the sole operative Indenture in connection with the Debentures.

         Section 5. Ratification and Reaffirmation of Indenture. Except as
hereby expressly amended, the Indenture shall remain in full force and effect
and the Indenture, as amended hereby, is ratified and confirmed.

         Section 6. Interpretation. In the event of any conflict between the
provisions of the Indenture and the provisions of this Supplemental Indenture,
the provisions of this Supplemental Indenture shall control.

         Section 7. Binding Effect. This Supplemental Indenture shall inure to
the benefit of and shall be binding upon Interpore, Cross, the Trustee, the
owners of the Debentures and their respective successors and assigns.

         IN WITNESS WHEREOF, INTERPORE and CROSS have caused this Supplemental
Indenture to be signed in each of their names, and FIFTH THIRD BANK, as Trustee,
has caused this Supplemental Indenture to be signed in its name, all as of the
day and year first above written.

- --------------------

* Effect of dilutive securities would have been anti-dilutive; accordingly, the
amounts are excluded from shares used in computing diluted earnings per share.

Shares issuable from the convertible subordinated debentures were excluded from
the calculation of diluted earnings per share because their effect would have
been anti-dilutive.
