                                  May 21, 1999


       The 1999 annual meeting of the stockholders of Interpore International,
Inc. will be held at 9:00 a.m. local time, on May 21, 1999, at our executive
offices at 181 Technology Drive, Irvine, California 92618 for the following
purposes:

       1. To elect two Class I Directors to hold office until the annual meeting
of stockholders in the year 2002 and until the election and qualification of
their respective successors;

       2. To consider and vote upon a proposal to amend and restate the Employee
Qualified Stock Purchase Plan of Interpore International, Inc. ("Q.S.P. Plan")
which, among other things, would increase the number of shares of Common Stock
that may be issued pursuant to the Q.S.P. Plan;

       3. To consider and vote upon a proposal to approve the adoption of the
Interpore Cross International 1999 Consultants Stock Option Plan (the
"Consultants Option Plan") which would provide for the issuance of options to
purchase up to 300,000 shares of Common Stock; and

       4. To transact such other business as may properly come before the
meeting.

       Only stockholders of record at the close of business on April 13, 1999

                         ------------------------------
                             SOLICITATION OF PROXIES

       The accompanying proxy is solicited on behalf of the Board of Directors
of Interpore International, Inc. for use at the annual meeting of stockholders
to be held at our executive offices located at 181 Technology Drive, Irvine,
California 92618, on May 21, 1999 at 9:00 a.m. local time, and at any and all
adjournments or postponements thereof.

       All shares represented by each properly executed, unrevoked proxy
received in time for the meeting will be voted in the manner specified therein.
If the manner of voting is not specified in an executed proxy, the proxy will be
voted FOR the election of the two nominees to the Board of Directors listed
herein, the approval of the amended and restated Q.S.P. Plan, and the approval
and adoption of the Consultants Option Plan.

       You have the power to revoke your proxy at any time before it is voted. A
proxy may be revoked by delivering a written notice of revocation to our
Secretary, by presenting a later-dated proxy, or by attendance at the meeting
and voting in person.

       This proxy statement is being mailed to our stockholders on or about
April 16, 1999. We will pay for the expense of soliciting proxies. Expenses
include reimbursement paid to brokerage firms and others for their expenses
incurred in forwarding solicitation material regarding the meeting to beneficial
owners of the voting stock. Solicitation of proxies will be made by mail.
Further solicitation of proxies may be made by telephone or oral communication
by our regular employees, who will not receive additional compensation for such
solicitation.

                      OUTSTANDING SHARES AND VOTING RIGHTS

       Only if you held any of the 13,491,029 shares of Common Stock and 31,573
shares of Series E Preferred Stock outstanding at the close of business on the
record date, April 13, 1999, will you be entitled to notice of and to vote at
the meeting or any adjournment or postponement thereof. You will be entitled to
cast one vote for each share of Common Stock on each matter to be considered at
the meeting, and 1.0045 or 1.0058 votes (depending on issuance date) for each
share of Series E Preferred Stock, you held on April 13, 1999. Accordingly, an
aggregate of 13,522,755 votes may be cast on each matter to be considered at the
meeting.

       In order to constitute a quorum and to transact business at the meeting,
a majority of the outstanding shares on the record date must be represented at
the meeting. Shares represented by proxies that reflect abstentions or "broker
non-votes" (i.e., shares held by a broker or nominee which are represented at
the meeting, but not empowered to vote on a particular proposal) will be counted
as shares that are present and entitled to vote for purposes of determining the
presence of a quorum. Directors will be elected by a favorable vote of a
majority of the aggregate votes present, in person or by proxy, at the meeting.
Accordingly, neither abstentions, nor broker non-votes, will affect the election
of candidates receiving the majority of votes. In addition, a simple majority of
the shares voting may elect all of the directors. The proposals to (i) approve
the amended and restated Q.S.P. Plan and (ii) approve and adopt the Consultants
Option Plan require the affirmative vote of a majority of the aggregate votes of
the outstanding shares of Common Stock and Series E Preferred Stock.
Accordingly, proxies reflecting

<PAGE>   4


abstentions and broker non-votes by certain beneficial owners, will have the
same effect as votes against such proposals.

         SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

       The following table sets forth the amount and percentage of the
outstanding shares of the Common Stock, which, according to the information
supplied to us, are beneficially owned by (1) each person who, to our knowledge,
is the beneficial owner of more than 5% of the outstanding Common Stock, (2)
each person who is currently a director, two of whom are also nominees for
election as a director, (3) each Named Executive Officer, as defined on page 8
hereof, and (4) all current directors and executive officers as a group. Except
for information based on Schedules 13G, as indicated in the footnotes,
beneficial ownership is stated as of April 13, 1999. Except to the extent
indicated in the footnotes to the following table, to our knowledge, the person
or entity listed has sole voting or dispositive power to the shares which are
deemed beneficially owned by such person or entity. At April 13, 1999 we also
had outstanding 31,573 shares of Series E Convertible Preferred Stock which
votes together with the Common Stock on an as-converted basis. None of the
persons in the following table own any shares of the Series E Convertible
Preferred Stock.

                                   PROPOSAL 1

                              ELECTION OF DIRECTORS

       Our Board of Directors currently consists of six members. On May 7, 1998,
we combined our business with that of Cross Medical Products, Inc., a Delaware
corporation ("Cross") resulting in Cross becoming our wholly-owned subsidiary
(the "Merger"). Prior to the Merger, the Board of Directors consisted of a five
member non-classified Board including William A. Eisenecher, G. Bradford Jones,
David C. Mercer, Guy P. Nohra and George W. Smyth, Jr. At the time of the
Merger, we reincorporated from California to Delaware and adopted a Certificate
of Incorporation that established a six member board. Our Certificate of
Incorporation provides for the classification of the Board of Directors into
three classes, as nearly equal in number as possible, with staggered terms of
office. The Certificate of Incorporation also provides that upon the expiration
of the term of office for a class of directors, nominees for such class will be
elected for a term of three years or until their successors are duly elected and
qualified. The merger agreement provided that three members of the Board would
be designated by Cross (the "Initial Cross Directors") and three were designated
by our company (the "Initial Interpore Directors"). The Merger Agreement further
provided (1) that the persons serving as Initial Interpore Directors would be
David C. Mercer, William A. Eisenecher and G. Bradford Jones and (2) the persons
serving as the Initial Cross Directors would be Joseph A. Mussey, Daniel A.
Funk, M.D. and Robert J. Williams. Messrs. Mercer and Mussey were designated as
Class III Directors to serve until our third annual meeting of stockholders
following the Merger; Messrs. Eisenecher and Funk were designated as Class II
Directors to serve until the second annual meeting of our stockholders

<PAGE>   6



following the Merger; and Messrs. Jones and Williams were designated as Class I
Directors to serve until the first annual meeting of our stockholders following
the Merger.

       The term of the Class I Directors has expired and two nominees for
director are to be elected as Class I Directors. The two nominees are G.
Bradford Jones and Robert J. William, each of whom currently serves as a Class I
Directors. The Class II Directors have one year remaining on their term of
office and the Class III Directors have two years remaining on their term of
office.

REQUIRED VOTE

       Directors will be elected by the affirmative vote of a majority of the
aggregate votes present and entitled to vote, in person or by proxy, at the
meeting. Abstentions or broker non-votes as to the election of directors will
not affect the election of the candidates receiving the majority of votes.
Unless otherwise instructed, the shares represented by the proxies will be voted
FOR the election of the two nominees named below as directors. Although it is
anticipated that each nominee will be able to serve as a director, should any
nominee become unavailable to serve, the proxies will be voted for such other
person or persons as may be designated by our Board of Directors.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE "FOR"
THE ELECTION OF EACH NOMINEE TO THE BOARD OF DIRECTORS.

       The information set forth below as to each nominee for director has been

MEETINGS AND COMMITTEES OF THE BOARD OF DIRECTORS

       During the fiscal year ended December 31, 1998 and prior to the Merger,
the Board of Directors met four times. After the Merger, the Board of Directors
met six times. In 1998, all incumbent directors attended at least 75% of the
total number of meetings of the Board of Directors and the total number of
meetings held by all committees of the Board of Directors on which that director
served.

       We have an Audit Committee and a Compensation and Stock Option Committee.
Prior to the date of the Merger, Messrs. Eisenecher, Jones and Guy Nohra served
on the Audit Committee, which met one time. After the Merger, Messrs.
Eisenecher, Funk, Jones, and Williams were appointed to the Audit Committee,
which met one time. The Audit Committee's responsibilities include: (1)
recommending the selection of our independent public auditors to the Board of
Directors, (2) consulting with the independent auditors with regard to the plan
and scope of audit, (3) reviewing, in consultation with the independent
auditors, their report of audit or proposed report of audit, and the
accompanying management letter, if any, and (4) consulting with the independent
auditors and management with regard to the adequacy of internal controls.

       Prior to the Merger, Messrs. Mercer, Jones and Nohra served on the
Compensation Committee and Messrs. Jones and Nohra served on the Stock Option
Committee, both of which met one time during the fiscal year 1998. After the
Merger, the Compensation Committee and the Stock Option Committee were combined
and Messrs. Eisenecher, Funk, Jones and Williams were appointed to the
Compensation and Stock Option Committee, which met six times. The Compensation
and Stock Option Committee reviews and approves executive salaries, considers
awards to be granted under our incentive bonus plan, administers stock option
grants under the our stock option plans and performs other related functions
upon request of the Board of Directors.

BOARD COMPENSATION AND BENEFITS

       The Stock Option Plan for Non-Employee Directors (the "Non-Employee
Directors Plan") provides for the automatic grant of non-qualified stock options
to purchase shares of Common Stock to eligible non-employee directors. On May
25, 1995, under the terms of the Non-Employee Directors Plan, each director who
was not an employee was automatically granted an initial option to purchase
15,000 shares of Common Stock, effective as of May 25, 1995, at an exercise
price of $5.75 per share. Non-employee directors who are first appointed or
elected to the Board of Directors after May 25, 1995 will be automatically
granted an initial option to purchase 15,000 shares of Common Stock, effective
on the date of election or appointment to the Board of Directors. In addition to
the initial grant, non-employee directors are automatically granted options to
purchase 2,500 shares on the date of the annual meeting of stockholders in every
year following the initial grant to such director, provided that the director is
re-elected at the meeting if such director's term is expiring.

       Each non-employee director is entitled to be paid a fee of $1,000 per
Board meeting attended in person (or by phone if a regularly scheduled meeting)
or for a committee meeting attended in person if on a date where a full Board
meeting is not being held (the "Directors' Fee"). Alternatively, pursuant to an
irrevocable election made at least six months prior to the Board meeting date, a
non-employee director may elect to automatically receive non-qualified stock
options under the Non-Employee Directors Plan covering 500 shares of Common
Stock in lieu of the Directors' Fee. The price per share of Common Stock subject
to each option granted under the plan is 100% of the closing price of the Common
Stock on the Nasdaq Stock Market on the day prior to such meeting. The options
become exercisable in four cumulative annual installments of 25% of the shares
covered by the option, commencing with the first anniversary from the date of
grant.

       During fiscal year 1998, non-employee directors received options to
purchase 500 shares of Common Stock, in lieu of the Director's Fee, as follows:
exercise price of $4.50 (Eisenecher, Jones), $4.75 (Eisenecher, Funk, Jones,
Williams), $6.50 (Eisenecher, Jones), $7.625 (Jones) and $8.313 (Eisenecher,
Jones). Each non-employee director also received an option to purchase 2,500
shares of Common Stock, at an exercise price of $6.50, in connection with the
1998 annual meeting.

EMPLOYMENT AGREEMENTS, TERMINATION OF EMPLOYEE AND CHANGE IN CONTROL
ARRANGEMENTS; INDEMNIFICATION AGREEMENTS

       We entered into Employment Agreements with each of our executive
officers. Pursuant to the Employment Agreements, each of the officers receive
annual base salaries as determined from time to time by the Board of Directors.
In addition, the executives are entitled to receive incentive compensation,
including bonuses and stock options pursuant to the terms of the plans adopted
by the Board of Directors at their sole discretion. In the event of a change in
control, each of the executives will be entitled to receive an amount equal to
approximately two times the executive's current annual base salary and bonus, to
be paid out over a period of twenty-four months. The Employment Agreements also
provide each of the executives with insurance, vacation and sick leave benefits.

       The Employment Agreements provide that employment of each of the
executives is "at-will" and may be terminated by us at any time. If the
executive is terminated by us without cause, we will continue to pay the
executive his basic salary and provide fringe benefits at the level in place at
the termination date for 12 months and will provide outplacement services at a
cost to us not to exceed the executive's basic salary for one month. We may
terminate payment of the basic salary, fringe benefits and outplacement services
during the severance period if the executive accepts other employment or is in
breach of the non-competition and confidentiality obligations of the Employment
Agreement.

       We have also entered into Indemnification Agreements with our executive
officers and directors providing for indemnification of such persons to the
fullest extent authorized, permitted or allowed by law.

COMPENSATION AND STOCK OPTION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

       General Philosophy. The Compensation and Stock Option Committee reviews
and determines salaries, bonuses and all other elements of the compensation
packages offered to the executive officers, including its Chief Executive
Officer, and establishes our general compensation policies.

       We desire to attract, motivate and retain high quality employees who will
enable us to achieve our short- and long-term strategic goals and values. We
participate in a high-growth environment where substantial competition exists
for skilled employees. Our ability to attract, motivate and retain high caliber
individuals is dependent in large part upon the compensation packages we offer.

       We believe that our executive compensation programs should reflect our
financial and operating performance. In addition, individual contribution to our
success should be supported and rewarded.

       Our executive compensation has been based on four primary components:
base salary, incentive bonus, long-term incentives in the form of stock options
and an executive automobile program. The Committee believes that these incentive
components have maintained annual executive compensation at competitive levels
and have provided an effective means of retaining, motivating and rewarding high
quality management.

       Under the 1993 Omnibus Budget Reconciliation Act ("OBRA"), income tax
deductions of publicly-traded companies in tax years beginning on or after
January 1, 1994 may be limited to the extent total compensation (including base
salary, annual bonus, stock option exercises and non-qualified benefits) for
certain executive officers exceeds $1 million (less the amount of any "excess
parachute-payments" as defined in Section 280G of the Code) in any one year.
Under OBRA, the deduction limit does not apply to payments which qualify as
"performance-based." To qualify as "performance-based," compensation payments
must be based solely upon the achievement of objective performance goals and
made under a plan that is administered by a committee of outside directors. In
addition, the material terms of the plan must be disclosed to and approved by
stockholders, and the compensation committee must certify that the performance
goals were achieved before payments can be made. The Committee attempts to
design our compensation programs to conform with the OBRA legislation and
related regulations so that total compensation paid to any employee will not
exceed $1 million in any one year, except for compensation payments which
qualify as "performance-based." We may, however, pay compensation which is not
deductible in limited circumstances when sound management so requires.

       Base Salary. Base salary for each of the executive officers, including
the Chief Executive Officer, is targeted at the average salaries paid for such
positions by competitive medical products companies of similar size,

<PAGE>   13





with additional consideration given to biotech companies for selected positions.
Industry and custom surveys are used to establish competitive practices.
Salaries for executives are reviewed by the Committee on an annual basis and may
be adjusted at that time based on our performance, the Committee's assessment of
the individual's contribution to our operations and changes in competitive pay
levels. Following the Merger, the base salaries of the executive officers,
including the Chief Executive Officer, were evaluated and adjusted according to
the factors discussed above including a review of the market pay trends and
their efforts in connection with the Merger. Mr. Mercer's base salary was
increased from $180,000 to $200,000, effective as of May 18, 1998.

       Incentive Bonus Plan. In an effort to encourage and reward operating
performance on an annual basis, all employees, including executive officers but
excluding those employees compensated by commission or some other form of bonus
compensation, are eligible for annual bonuses. Target bonus awards for each
position, expressed as a percent of base salary ranging from 5% to 25%, were
established by surveying awards paid by competitive companies of similar size.
The target bonus awards vary by employment level, with the target award for the
executive officers established at 25% of base salary. For fiscal year 1998,
actual bonus awards could have ranged from 0% to 150% of the targeted award,
based upon actual performance against targeted objectives. Bonus awards are
based upon our actual operating results as compared to targeted annual operating
results approved by the Committee at the beginning of each fiscal year. While we
did not achieve our targeted operating results for 1998, the Board of Directors
approved a 50% bonus payout to eligible employees on a discretionary basis to
reflect accomplishment of specific business objectives.

       The committee granted these bonuses after taking other considerations
into account, including the efforts of our management, an evaluation of their
performance, the relative ranking of the compensation of the officers vis-a-vis
other similarly situated companies, the impact on morale and performance of
granting no bonuses, the potential that certain employees may leave or be hired
by competitors, the magnitude by which we failed to meet our stated targets, our
development activity, the many variables which may have impacted performance
this past period, and certain accounting charges and non-recurring write-offs
which affected our performance notwithstanding the efforts of the employees. The
committee also considered our growth rate and the qualitative performance of
each of the bonus eligible employees.

       Long Term Incentives. We offer our executives and other key employees
long-term incentives primarily through stock option grants under its stock
option plans. Stock option grants are intended to motivate executives to improve
long-term stock performance, and thus are tied directly to stockholders'
interests. Stock options are granted at the prevailing market price on the date
of grant and will, thus, only have value if our stock price rises. Stock options
generally vest over four years. The Compensation and Stock Option Committee,
composed of Messrs. Eisenecher, Jones, Funk and Williams, administers the plan
and determines which employees are to receive option grants and the number of
options to be granted.

       Executive Automobile Program. We provide each of our executive officers
with an automobile on a three-year, closed-end lease. We believe that providing
each executive with the use of an automobile will increase the value of the
after-tax compensation of each executive to more competitive levels.

Committee:

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

       Section 16(a) of the Securities Exchange Act of 1934, as amended
("Exchange Act"), requires the directors and executive officers, and persons who
own more than 10% of a registered class of the equity securities, to file
initial reports of ownership and reports of changes in ownership with the
Securities and Exchange Commission (the "SEC") and The Nasdaq Stock Market. Such
persons are required by SEC regulations to furnish us with copies of all Section
16(a) forms they file.

       Based solely on our review of copies of such forms received by us with
respect to fiscal 1998, or written representations from certain reporting
persons, we believe that during fiscal 1998 all of our directors and executive
officers and persons who own more than 10% of the Common Stock complied with the
reporting requirements of Section 16(a), except that (i) a Form 3 for Philip A.
Mellinger in connection with his appointment as a Vice President, Product
Development on May 7, 1998 was not filed until January 27, 1999; (ii) a Form 4
for William A. Eisenecher in connection with an exercise of options on March 23,
1998 was not filed until December 9, 1998; (iii) a report for Edwin C. Shors,
Ph.D. in connection with an exercise of options on April 10, 1998 was not filed
until a Form 5 was filed on February 16, 1999; and (iv) an amended Form 3 for
Robert J. Williams in connection with reporting common stock holdings was not
filed until April, 1999.

                                   PROPOSAL 2

                                 APPROVAL OF THE
         AMENDED AND RESTATED EMPLOYEE QUALIFIED STOCK PURCHASE PLAN OF
                          INTERPORE INTERNATIONAL, INC.

       On November 13, 1998, the Board of Directors adopted, subject to the
approval of the stockholders, the Amended and Restated Q.S.P. Plan. At the
meeting, you will be asked to approve the amendments to the Q.S.P. Plan. The
amendments to the Q.S.P. Plan increase the number of shares of Common Stock
authorized to be sold pursuant to options granted under the Q.S.P. Plan to
300,000 shares. Without the amendment , the 100,000 shares originally authorized
for issuance under the Q.S.P. Plan could be exhausted prior to the end of 1999,
based on the current number of our employees and average participation rates.
Section Four of the Q.S.P. Plan has also been amended to correct certain
clerical errors relating to the eligibility of employees of our subsidiaries to
participate in the Q.S.P. Plan.

       We believe that the changes to our Amended and Restated Q.S.P. Plan will
enable us and our subsidiaries to attract and retain more experienced and
capable persons who can make significant contributions to the further growth and
success.

DESCRIPTION OF THE Q.S.P. PLAN

       The following is a description of the material provisions of the Q.S.P.
Plan. The summary that follows is not intended to be complete, and reference
should be made to the Q.S.P. Plan for a complete statement of its terms and
provisions. Copies of the Q.S.P. Plan will be made available at the Meeting and
may also be obtained by making written request of our Secretary.

       The Q.S.P. Plan provides for the grant of options to purchase shares of
Common Stock (through payroll deductions) during six-month offering periods. The
purpose of the Q.S.P. Plan is to assist eligible employees of the company in
acquiring stock ownership pursuant to a plan which is intended to qualify as an
"employee stock purchase plan" under Section 423 of the Internal Revenue Code of
1986, as amended (the "Code").

       The Q.S.P. Plan is not subject to the provisions of the Employee
Retirement Income Security Act of 1974, as amended, and is not qualified under
Section 401(a) of the Code. We use the proceeds from the sale of Common Stock
under the Q.S.P. Plan for general corporate purposes.

SECURITIES SUBJECT TO THE Q.S.P. PLAN

       The total number of shares of Common Stock currently authorized for
issuance under the Q.S.P. Plan is 100,000. The Amended and Restated Q.S.P. Plan
would authorize the issuance of an aggregate of 300,000 shares of Common Stock.
We believe that without an increase in the number of shares issuable under the
Q.S.P. Plan, the 100,000 shares currently issuable will be exhausted prior to
the end of 1999. The Administrator of the Q.S.P. Plan will make appropriate
adjustments to the aggregate number of shares of Common Stock subject to the
Plan, the number of shares of Common Stock subject to outstanding options and
the price per share thereof in the event of any merger, consolidation,
reorganization, recapitalization, stock dividend, stock split, recapitalization
or other change in our corporate structure.

GRANT OF OPTIONS; OFFERING PERIOD

       Participating eligible employees are granted nontransferable six-month
options to purchase shares of Common Stock. The options are granted on the first
day of a six-month period (the "Date of Grant"), referred to as an "Offering
Period" and are generally automatically exercised on the last day of the
Offering Period (the "Date of Exercise"). Offering Periods are set by the
Administrator and commence on May 1 and November 1 of each year.

ELIGIBILITY TO PARTICIPATE

       In order to be eligible to participate in the Q.S.P. Plan, an individual
must have been, prior to any Offering Period:

<PAGE>   16


       -      employed by us or our subsidiaries for not less than one year
              prior to the Date of Grant;

       -      employed by us or our subsidiaries for more than 20 hours per
              week; and

       -      employed by us or our subsidiaries for more than five months
              during each calendar year.


       The amendment clarifies that employees of our Subsidiaries are eligible
to participate in the Q.S.P. Plan. Directors who are not our employees or
employees of our subsidiaries are not eligible to participate in the Plan.
Eligibility for options granted under the Q.S.P. Plan is subject to restrictions
imposed by the Code. Refer to Section Eight of the Q.S.P. Plan.

ELECTION TO PARTICIPATE

       An eligible employee may enroll in the Q.S.P. Plan by submitting a
completed and executed written payroll deduction authorization form. An
employee's authorization will enroll the employee in the Q.S.P. Plan for each
successive Offering Period until the employee either amends the authorization,
withdraws from participation under the Q.S.P. Plan or ceases to remain eligible
to participate in the Q.S.P. Plan.

PAYROLL DEDUCTIONS

       Each participating employee elects to reduce the cash compensation
payable by us through payroll deductions by an amount equal to a specified whole
percentage of Base Pay (not to exceed 10%) payable on each payday. "Base Pay"
means the gross pay received as cash compensation for services rendered,
generally excluding overtime payments, sales commission, incentive compensation,
bonuses and other special payments. Payroll deductions may not be changed with
respect to an Offering Period during that Offering Period.

       Throughout the Offering Period, we credit the amount of each employee's
payroll deductions to an account established under the Q.S.P. Plan for the
employee. An employee's payroll deductions are generally transferred from this
account to us upon the automatic exercise of the employee's option to purchase
shares of Common Stock under the Q.S.P. Plan at the end of the Offering Period.
Employees do not receive any interest on payroll deductions credited to their
accounts under the Q.S.P. Plan.

OPTION PRICE

       Options granted under the Q.S.P. Plan entitle a participating employee to
purchase the number of shares of Common Stock determined by dividing the
employee's total payroll deductions for the Offering Period by the purchase
price for the shares of Common Stock, excluding fractional sharesup to a maximum
of 5,000 shares. The purchase price for such Common Stock equals the lesser of
85% of the fair market value of such shares of Common Stock on (i) the Date of
Grant (the first day of the Offering Period), or (ii) the Date of Exercise (the
last day of the Offering Period). For so long as our Common Stock is listed as a
National Market Issue under the Nasdaq National Market System, the fair market
value of a share of Common Stock is determined to be the last sales price on a
given date.

CESSATION OF PARTICIPATION

       An employee will cease to participate in the Q.S.P. Plan when the
employee (i) delivers to us written instructions to terminate their
participation in the Q.S.P. Plan, (ii) resigns or is discharged from employment
with us, (iii) except under certain circumstances, has a leave of absence, or
(iv) dies. Upon cessation of participation by an employee, the employee's
payroll deductions under the Q.S.P. Plan will automatically cease. If a
cessation of participation occurs during the last two weeks of an Offering
Period, the employee's Option will be exercised on the last day of the Offering
Period. Upon cessation of participation at any other time, any balance of
payroll deductions credited to the employee's account under the Q.S.P. Plan will
be paid to the employee in cash in one lump sum as soon as practicable after
cessation of participation, without payment of any interest thereon.


<PAGE>   17


ADMINISTRATION OF THE Q.S.P. PLAN

       Our Chief Executive Officer administers the Q.S.P. Plan. We pay all costs
of administering the Q.S.P. Plan. The Q.S.P. Plan provides for the
indemnification of the administrator for liability, loss, costs, damages,
attorneys' fees and other expenses the administrator may incur in connection
with administration of the Q.S.P. Plan.

RIGHTS AS A STOCKHOLDER; TRANSFERABILITY

       No participating employee has any rights as a stockholder as to the
shares of Common Stock covered by an option until such shares have been issued
and delivered to the participating employee or account following the exercise of
such employee's option. No adjustment will be made for dividends or
distributions or other rights for which the record date is prior to the date of
such issuance. No option granted under the Q.S.P. Plan may be assigned or
transferred by the employee, except by will or the laws of descent and
distribution. During the lifetime of the employee, the option may be exercised
only by the employee.

CERTAIN RESTRICTIONS ON RESALE

       Shares of Common Stock issued upon the exercise of options granted under
the Q.S.P. Plan may be subject to restrictions on resale. Participating
employees who are "affiliates" within the meaning of the Securities Act and who
wish to offer or sell these shares must comply with the registration
requirements of the Securities Act, unless an exemption applies.

AMENDMENT AND TERMINATION OF THE Q.S.P. PLAN

       The Board of Directors may not, without prior stockholder approval, amend
the Q.S.P. Plan so as to increase the maximum number of shares of Common Stock
subject to the Q.S.P. Plan, change the designation or class of employees
eligible to receive options under the Q.S.P. Plan or amend the Q.S.P. Plan in
any manner which would cause the Q.S.P. Plan to cease to be an employee stock
purchase plan qualified under Section 423(b) of the Code.

       Although we expect to continue the Q.S.P. Plan until all shares of the
Common Stock reserved for issuance under the Q.S.P. Plan have been issued, the
Board of Directors may terminate the Q.S.P. Plan at any time with respect to any
shares not then subject to an option under the Q.S.P. Plan, and except as
indicated above, may modify the Q.S.P. Plan from time to time.

FEDERAL INCOME TAX CONSEQUENCES ASSOCIATED WITH THE Q.S.P. PLAN

       The Q.S.P. Plan is intended to qualify as an "employee stock purchase
plan," as defined in Section 423 of the Code. A summary of the Federal income
tax aspects of the Q.S.P. Plan are set forth below.

       No taxable income will result to an employee on the date options are
granted under the Q.S.P. Plan (i.e., the first day of the Offering Period) or on
the date the options are exercised (i.e., the last day of the Offering Period).
If the employee does not dispose of the shares of Common Stock purchased upon
exercise of the options within two years after the date on which the options
were granted or within one year after the date on which such shares were
acquired by the employee (the "Holding Period"), or the employee dies while
owning the shares, the employee will be taxed in the year in which the shares
are disposed of, or the year closing with the employee's death, whichever
applies, as follows:

              (a) The employee will be subject to ordinary income tax on an
       amount equal to the lesser of (i) the excess, if any, of the fair market
       value of the shares of Common Stock on the date on which they were
       disposed of or the employee died, over the amount paid for the shares of
       Common Stock, or (ii) the excess of the fair market value of the shares
       of Common Stock on the date the options were granted, over the option
       price; and

              (b) Any further gain realized by the employee on the disposition
       of the shares of Common Stock (after increasing the basis of these shares
       of Common Stock by the amount of ordinary income realized as described in
       (a) above) will be taxed as capital gain.

<PAGE>   18



       If the employee disposes of the shares of Common Stock purchased upon
exercise of the options before the expiration of the Holding Period, the
employee will realize ordinary income, reportable for the year of the
disposition of such shares of Common Stock, to the extent of the excess of the
fair market value of such shares of Common Stock on the date on which the
options were exercised, over the option price for such shares of Common Stock.
Any additional gain realized will be taxable as capital gain. If the Common
Stock is disposed of before the expiration of the Holding Period and the amount
realized is less than the fair market value of the Common Stock at the time of
exercise, the employee will report (i) ordinary income to the extent of the
excess of the fair market value of such Common Stock on the date on which the
options were exercised, over the option price for such Common Stock and (ii)
capital loss to the extent the fair market value of such Common Stock on the
exercise date exceeds the amount realized on the sale. We are entitled to a tax
deduction only to the extent that an employee realizes ordinary income due to a
disposition of the Common Stock before the expiration of the Holding Period.

       The rules governing the tax treatment of options and an optionee's
receipt of shares in connection with such grants are quite technical. The above
description of tax consequences is necessarily general in nature and does not
purport to be complete. Moreover, statutory provisions are, of course, subject
to change, as are their interpretations, and their application may vary in
individual circumstances. Finally, the tax consequences under applicable state
law may not be the same as under the federal income tax laws.

REQUIRED VOTE

       The affirmative vote of a majority of the outstanding shares of Common
Stock is required to approve the Amended and Restated Q.S.P. Plan.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE "FOR"
THE APPROVAL OF THE AMENDED AND RESTATED Q.S.P. PLAN.



                                   PROPOSAL 3

                  APPROVAL AND ADOPTION OF THE INTERPORE CROSS
                INTERNATIONAL 1999 CONSULTANTS STOCK OPTION PLAN

GENERAL

       On March 9, 1999, the Board of Directors adopted, subject to the approval
of the stockholders, the Interpore Cross International 1999 Consultants Stock
Option Plan, a copy of which is attached hereto as Appendix A (the "Consultants
Option Plan"). The Consultants Option Plan provides for the grant of options to
acquire up to 300,000 shares of Common Stock to non-employee consultants and
advisors of our company and our subsidiaries.

       We believe that the successful development of new products depends on our
ability to attract and motivate qualified scientific, technical and professional
persons who are available only on a part time basis to provide their technical
and professional advice. We also believe that a separate option plan dedicated
to consultants and advisors will prove helpful in attracting and rewarding such
persons.

DESCRIPTION OF THE CONSULTANTS OPTION PLAN

       The following is a description of the material provisions of the
Consultants Option Plan. The summary that follows is not intended to be complete
and you should carefully review the Consultants Option Plan for a complete
statement of its terms and provisions.

       The Consultants Option Plan provides for the grant of options to purchase
shares of Common Stock to benefit eligible consultants. Under certain provisions
of the Internal Revenue Code, option grants under the Consultants Option Plan
cannot qualify as an incentive stock option. The options are granted in
consideration of a consultant's agreement to render faithful and efficient
services to us.

SECURITIES SUBJECT TO THE CONSULTANTS OPTION PLAN

       The total number of shares of Common Stock proposed to be authorized for
issuance under the Consultants Option Plan is 300,000. The Compensation and
Stock Option Committee will make appropriate adjustments to the aggregate number
of shares of Common Stock subject to the Plan, the number of shares of Common
Stock subject to outstanding options and the price per share thereof in the
event of any stock dividends, stock splits, recapitalizations, mergers or
certain other similar changes in the Common Stock or other types of
reorganizations.

ADMINISTRATION OF THE CONSULTANTS OPTION PLAN

       The Compensation and Stock Option Committee will administer the
Consultants Option Plan which is intended to satisfy the requirements of Rule
16b-3 under the Exchange Act. Subject to the terms of the Consultants Option
Plan, the Committee has the authority to:

       -      select the consultants to whom grants are to be made;

       -      designate the number of shares of Common Stock to be covered by
              such grants;

       -      determine the exercise price of options;

       -      establish the period of exercisability of options; and

       -      make all other determinations and to take all other actions
              necessary or advisable for the administration of the Consultants
              Option Plan.


       The dates on which options first become exercisable and on which they
expire shall be specified in individual option agreements, which will set forth
the specific terms of the options, subject to the requirements of the
Consultants Option Plan. Such agreements will generally provide that options
expire following the termination of the optionee's status as a consultant
although the Committee may provide that options continue to be exercisable
following a termination.

       The Committee may also, in its discretion, provide that an option will
expire at specified times following, or become exercisable in full upon, the
occurrence of certain specified extraordinary corporate events. Those events
include a merger, consolidation or dissolution, or a sale of substantially all
of our assets. The Committee may also give optionees the right to exercise their
outstanding options in full during some period prior to such event, even though
the rights have not yet otherwise become fully exercisable. Notwithstanding the
foregoing, upon a "Corporate Transaction" (as defined in the Consultants Option
Plan), all outstanding options may, at the option of the Committee, become
immediately exercisable if not assumed by the surviving corporation.

OPTION PRICE

       The Committee will set the price per share of the shares subject to each
option, subject only to the limitation that the price may not be less than par
value. The Consultants Option Plan permits the payment of the option exercise
price to be made:

       -      in cash (which may include an assignment of the right to receive
              the cash proceeds from the sale of Common Stock subject to the
              option);

       -      by delivery of shares of Common Stock previously owned by the
              optionee or issuable upon exercise of the options valued at their
              fair market value on the date of exercise, or delivery of other
              property;

       -      by a recourse promissory note payable to us; or

       -      by a combination of the foregoing.

       As a condition of exercise, the Committee may require that optionees also
provide for the payment of withholding tax obligations in connection with such
exercise.

CESSATION OF PARTICIPATION

       The Committee, in its sole discretion, shall determine the effect of all
matters and questions relating to termination of consultancy and exercisability
of any outstanding options in connection with any termination. If a

<PAGE>   20





consultant is terminated in certain circumstances, he or she may be required to
pay to us the benefit received on the exercise of any options granted under the
Consultants Option Plan and forfeit any unexercised options whether or not
vested.

RIGHTS AS A STOCKHOLDER

       No participating consultant has any rights as a stockholder as to the
shares of Common Stock covered by an option until all conditions to the issuance
of certificates for such shares have been satisfied and such certificates have
been issued and delivered to the participating consultant or his or her account
following the exercise of such consultant's option.

OPTIONS NOT TRANSFERABLE

       Options granted under the Consultants Option Plan are not transferable
other than by will, by the laws of descent and distribution or pursuant to a
qualified domestic relations order (as defined in the Code), and may be
exercised during the optionee's lifetime only by the optionee.

AMENDMENT AND TERMINATION OF THE CONSULTANTS OPTION PLAN

       The Consultants Option Plan may be amended by the stockholders. The
Consultants Option Plan may also be wholly or partially amended or otherwise
modified, suspended or terminated at any time by the Board of Directors or the
Committee. Such termination will not affect the validity of any option
outstanding under the Consultants Option Plan on the date of termination. Other
than changes due to stock dividends, stock splits, recapitalizations, mergers or
other similar changes in the Common Stock or other types of reorganizations, the
Board of Directors and the Committee may not increase the number of shares
subject to the Consultants Option Plan without the approval of the stockholders.
Similarly, the Board of Directors and the Committee may not otherwise take
action to amend or modify the Consultants Option Plan in a manner requiring
stockholder approval as a matter of applicable law, regulation or rule without
the approval of stockholders.

FEDERAL INCOME TAX CONSEQUENCES ASSOCIATED WITH THE CONSULTANTS OPTION PLAN

       An optionee generally will not recognize taxable income on the grant of a
stock option under the Consultants Option Plan but will recognize ordinary
income on the exercise of such option. The amount of income recognized on the
exercise of an option generally will be equal to the excess, if any, of the fair
market value of the shares at the time of exercise over the aggregate exercise
price paid for the shares, regardless of whether the exercise price is paid in
cash or in shares or other property. Where ordinary income is recognized by an
optionee in connection with the exercise of an option, we will generally be
entitled to a deduction equal to the amount of ordinary income so recognized.
Upon disposition of the shares, the optionee will generally realize capital gain
or loss, and his basis for determining gain or loss will be the sum of the
option price paid for the shares plus the amount of ordinary income recognized
on the exercise of the option.

       The rules governing the tax treatment of options and an optionee's
receipt of shares in connection with such grants are quite technical. The above
description of tax consequences is necessarily general in nature and does not
purport to be complete. Moreover, statutory provisions are, of course, subject
to change, as are their interpretations, and their application may vary in
individual circumstances. Finally, the tax consequences under applicable state
law may not be the same as under the federal income tax laws.

REQUIRED VOTE

       The affirmative vote of a majority of the outstanding shares of Common
Stock is required to approve the Consultants Option Plan.

       THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE
"FOR" THE APPROVAL OF CONSULTANTS OPTION PLAN.

                                  ARTICLE III.
                               GRANTING OF OPTIONS

       3.1. Eligibility. Any consultant who is not an employee of the Company or
any Subsidiary and is selected by the Committee pursuant to Section 3.2(a)(i)
shall be eligible to be granted an Option.

       3.2. Granting of Options.

               (a) The Committee shall from time to time, in its sole
discretion, and subject to applicable limitations of this Plan:

                      (i)    Determine and select from among the key consultants
(including consultants who have previously received Options under this Plan)
such of them as in its opinion should be granted Options;

                      (ii)   Determine the number of shares to be subject to 
such Options granted to the selected key consultants;

                      (iii)  Determine the terms and conditions of such Options,
consistent with this Plan.

               (b) Upon the selection of a key consultant to be granted an
Option, the Committee shall instruct the Secretary of the Company to issue the
Option and may impose such conditions on the grant of the Option as it deems
appropriate. Without limiting the generality of the preceding sentence, the
Committee may, in its sole discretion and on such terms as it deems appropriate,
require as a condition on the grant of an Option to a consultant that the
consultant surrender for cancellation some or all of the unexercised options
which have been previously granted to him or her under this Plan or otherwise.
An Option, the grant of which is conditioned upon such surrender, may have an
exercise price lower (or higher) than the exercise price of such surrendered
option, may cover the same (or a lesser or greater) number of shares as such
surrendered option, may contain such other terms as the Committee deems
appropriate, and shall be exercisable in accordance with its terms, without
regard to the number of shares, price, exercise period or any other term or
condition of such surrendered option.

                                   ARTICLE IV.
                                TERMS OF OPTIONS

       4.1. Option Agreement. Each Option shall be evidenced by a written Option
Agreement, which shall be executed by the Optionee and an authorized officer of
the Company and which shall contain such terms and conditions as the Committee
shall determine, consistent with this Plan.

       4.2. Exercise Price. The price per share of the shares subject to each
Option shall be set by the Committee and specified in the Option Agreement;
provided, however, that such price shall be no less than the par value of a
share of Common Stock, unless otherwise permitted by applicable state law.

       4.3. Option Term. The term of an Option shall be set by the Committee in
its sole discretion. The Committee may extend the term of any outstanding Option
in connection with any Termination of Consultancy of the Optionee, or amend any
other term or condition of such Option relating to such a termination.

       4.4. Option Vesting.

               (a) The period during which the right to exercise an Option in
whole or in part vests in the Optionee shall be set by the Committee and the
Committee may determine that an Option may not be exercised in whole or in part
for a specified period after it is granted. At any time after grant of an
Option, the Committee may, in its sole discretion and subject to whatever terms
and conditions it selects, accelerate the period during which an Option vests.

               (b) No portion of an Option which is unexercisable at the
Optionee's Termination of Consultancy shall thereafter become exercisable,
except as may be otherwise provided by the Committee either in the Option
Agreement or by action of the Committee following the grant of the Option.

                                      A-3

<PAGE>   25


       4.5. Consideration. In consideration of the granting of an Option, the
Optionee shall agree, in the written Option Agreement, to render faithful and
efficient services to the Company or a Subsidiary, with such duties and
responsibilities as the Company or Subsidiary shall from time to time prescribe.
Nothing in the Plan or any Option Agreement shall confer upon any Optionee any
right to continue as a consultant for the Company or any Subsidiary or shall
interfere with or restrict in any way the rights of the Company and any
Subsidiary, which are hereby expressly reserved, to discharge any Optionee at
any time for any reason whatsoever.

                                   ARTICLE V.
                               EXERCISE OF OPTIONS

       5.1. Partial Exercise. An exercisable Option may be exercised in whole or
in part. However, an Option shall not be exercisable with respect to fractional
shares and the Committee may require that, by the terms of the Option Agreement,
a partial exercise be with respect to a minimum number of shares.

       5.2. Manner of Exercise. All or a portion of an exercisable Option shall
be deemed exercised upon delivery of all of the following to the Secretary of
the Company or his or her office:

               (a) A written notice complying with the applicable rules
established by the Committee stating that the Option, or a portion thereof, is
exercised. The notice shall be signed by the Optionee or other person then
entitled to exercise the Option or such portion;

               (b) Such representations and documents as the Committee, in its
sole discretion, deems necessary or advisable to effect compliance with all
applicable provisions of the Securities Act and any other federal or state
securities laws or regulations. The Committee may, in its sole discretion, also
take whatever additional actions it deems appropriate to effect such compliance
including, without limitation, placing legends on share certificates and issuing
stop-transfer notices to transfer agents and registrars;

               (c) In the event that the Option shall be exercised pursuant to
Section 7.1 by any person or persons other than the Optionee, appropriate proof
of the right of such person or persons to exercise the Option; and

               (d) Full cash payment to the Secretary of the Company for the
shares with respect to which the Option, or portion thereof, is exercised.
However, the Committee may, in its sole discretion (i) allow a delay in payment
up to thirty (30) days from the date the Option, or portion thereof, is
exercised; (ii) allow payment, in whole or in part, through the delivery of
shares of Common Stock owned by the Optionee, duly endorsed for transfer to the
Company with a Fair Market Value on the date of delivery equal to the aggregate
exercise price of the Option or exercised portion thereof; (iii) allow payment,
in whole or in part, through the surrender of shares of Common Stock then
issuable upon exercise of the Option having a Fair Market Value on the date of
Option exercise equal to the aggregate exercise price of the Option or exercised
portion thereof; (iv) allow payment, in whole or in part, through the delivery
of property of any kind which constitutes good and valuable consideration; (v)
allow payment, in whole or in part, through the delivery of a full recourse
promissory note bearing interest (at no less than such rate as shall then
preclude the imputation of interest under the Code) and payable upon such terms
as may be prescribed by the Committee; (vi) allow payment, in whole or in part,
through the delivery of a notice that the Optionee has placed a market sell
order with a broker with respect to shares of Common Stock then issuable upon
exercise of the Option, and that the broker has been directed to pay a
sufficient portion of the net proceeds of the sale to the Company in
satisfaction of the Option exercise price; or (vii) allow payment through any
combination of the consideration provided in the foregoing subparagraphs (ii),
(iii), (iv), (v) and (vi). In the case of a promissory note, the Committee may
also prescribe the form of such note and the security to be given for such note.
The Option may not be exercised, however, by delivery of a promissory note or by
a loan from the Company when or where such loan or other extension of credit is
prohibited by law.

       5.3. Conditions to Issuance of Stock Certificates. The Company shall not
be required to issue or deliver any certificate or certificates for shares of
stock purchased upon the exercise of any Option or portion thereof prior to
fulfillment of all of the following conditions:

               (a) The admission of such shares to listing on all stock
exchanges on which such class of stock is then listed;


                                      A-4

<PAGE>   26


               (b) The completion of any registration or other qualification of
such shares under any state or federal law, or under the rulings or regulations
of the Securities and Exchange Commission or of any other governmental
regulatory body which the Committee shall, in its sole discretion, deem
necessary or advisable;

               (c) The obtaining of any approval or other clearance from any
state or federal governmental agency which the Committee shall, in its sole
discretion, determine to be necessary or advisable;

               (d) The lapse of such reasonable period of time following the
exercise of the Option as the Committee may establish from time to time for
reasons of administrative convenience; and

of any shares purchasable upon the exercise of any part of an Option unless and
until certificates representing such shares have been issued by the Company to
such holders.

       5.5. Ownership and Transfer Restrictions. The Committee, in its sole
discretion, may impose such restrictions on the ownership and transferability of
the shares purchasable upon the exercise of an Option as it deems appropriate.

       6.1. Compensation Committee. The Compensation Committee (or another
committee or a subcommittee of the Board assuming the functions of the Committee
under this Plan) shall consist solely of two or more Independent Directors
appointed by and holding office at the pleasure of the Board, each of whom is
(i) a "non-employee director" (as defined by Rule 16b-3) and (ii) to the extent
required by the applicable provisions of Rule 16b-3, a "disinterested person" as
defined by Rule 16b-3. Appointment of Committee members shall be effective upon
acceptance of appointment. Committee members may resign at any time by
delivering written notice to the Board. Vacancies in the Committee may be filled
by the Board.

       6.2. Duties and Powers of Committee. It shall be the duty of the
Committee to conduct the general administration of this Plan in accordance with
its provisions. The Committee shall have the power to interpret this Plan and
the agreements pursuant to which Options are granted, and to adopt such rules
for the administration, interpretation, and application of this Plan as are
consistent therewith and to interpret, amend or revoke any such rules. Any such
grant under this Plan need not be the same with respect to each Optionee. In its
sole discretion, the Board may at any time and from time to time exercise any
and all rights and duties of the Committee under this Plan except with respect
to matters which under Rule 16b-3 or any regulations or rules issued thereunder,
are required to be determined in the sole discretion of the Committee.

       6.3. Majority Rule; Unanimous Written Consent. The Committee shall act by
a majority of its members in attendance at a meeting at which a quorum is
present or by a memorandum or other written instrument signed by all members of
the Committee.

       6.4. Compensation; Professional Assistance; Good Faith Actions. Members
of the Committee shall receive such compensation for their services as members
as may be determined by the Board. All expenses and liabilities which members of
the Committee incur in connection with the administration of this Plan shall be
borne by the Company. The Committee may, with the approval of the Board, employ
attorneys, consultants, accountants, appraisers, brokers, or other persons. The
Committee, the Company and the Company's officers and Directors shall be
entitled to rely upon the advice, opinions or valuations of any such persons.
All actions taken and all interpretations and determinations made by the
Committee or the Board in good faith shall be final and binding upon all
Optionees, the Company and all other interested persons. No members of the
Committee or Board shall be personally liable for any action, determination or
interpretation made in good faith with respect to this Plan or the


                                      A-5

Options and all members of the Committee and the Board shall be fully protected
by the Company in respect of any such action, determination or interpretation.

                                  ARTICLE VII.
                            MISCELLANEOUS PROVISIONS

        7.1. Not Transferable. Options under this Plan may not be sold, pledged,
assigned, or transferred in any manner other than by will or the laws of descent
and distribution or pursuant to a QDRO, unless and until such Options have been
exercised, or the shares underlying such Options have been issued, and all
restrictions applicable to such shares have lapsed. No Option or interest or
right therein shall be liable for the debts, contracts or engagements of the
Optionee or his or her successors in interest or shall be subject to disposition
by transfer, alienation, anticipation, pledge, encumbrance, assignment or any
other means whether such disposition be voluntary or involuntary or by operation
of law by judgment, levy, attachment, garnishment or any other legal or
equitable proceedings (including bankruptcy), and any attempted disposition
thereof shall be null and void and of no effect, except to the extent that such
disposition is permitted by the preceding sentence.

       During the lifetime of the Optionee only he or she may exercise an Option
(or any portion thereof) granted to him or her under the Plan, unless it has
been disposed of pursuant to a QDRO, in which case the Option may be exercised
only by the transferee. After the death of the Optionee, any exercisable portion
of an Option may, prior to the time when such portion becomes unexercisable
under the Plan or the applicable Option Agreement, be exercised by his or her
personal representative or by any person empowered to do so under the deceased
Optionee's will or under the then applicable laws of descent and distribution.

        7.2. Amendment, Suspension or Termination of this Plan. Except as
otherwise provided in this Section 7.2, this Plan may be wholly or partially
amended or otherwise modified, suspended or terminated at any time or from time
to time by the Board or the Committee. However, without approval of the
Company's stockholders given within twelve months before or after the action by
the Board or the Committee, no action of the Board or the Committee may, except
as provided in Section 7.3, increase the limits imposed in Section 2.1 on the
maximum number of shares which may be issued under this Plan, and no action of
the Committee or the Board may be taken that would otherwise require stockholder
approval as a matter of applicable law, regulation or rule. No amendment,
suspension or termination of this Plan shall, without the consent of the holder
of Options, alter or impair any rights or obligations under any Options
theretofore granted, unless the applicable Option Agreement itself otherwise
expressly so provides. No Options may be granted during any period of suspension
or after termination of this Plan, and in no event may any Option be granted
under this Plan after the first to occur of the following events:

               (a) The expiration of ten years from the date the Plan is adopted
by the Board; or

               (b) The expiration of ten years from the date the Plan is
approved by the Company's shareholders under Section 7.4.

        7.3. Changes in Common Stock or Assets of the Company, Acquisition or
Liquidation of the Company and Other Corporate Events.

               (a) Subject to Section 7.3(d), in the event that the Committee
determines that any dividend or other distribution (whether in the form of cash,
Common Stock, other securities, or other property), recapitalization,
reclassification, stock split, reverse stock split, reorganization, merger,
consolidation, split-up, spin-off, combination, repurchase, liquidation,
dissolution, or sale, transfer, exchange or other disposition of all or
substantially all of the assets of the Company, or exchange of Common Stock or
other securities of the Company (including, but not limited to, a Corporate
Transaction), issuance of warrants or other rights to purchase Common Stock or
other securities of the Company, or other similar corporate transaction or
event, in the Committee's sole discretion, affects the Common Stock such that an
adjustment is determined by the Committee to be appropriate in order to prevent
dilution or enlargement of the benefits or potential benefits intended to be
made available under the Plan or with respect to an Option, then the Committee
shall, in such manner as it may deem equitable, adjust any or all of


                                      A-6

<PAGE>   28


                      (i) the number and kind of shares of Common Stock (or 
other securities or property) with respect to which Options may be granted under
the Plan (including, but not limited to, adjustments of the limitations in
Section 2.1 on the maximum number and kind of shares which may be issued),

                      (ii) the number and kind of shares of Common Stock (or 
other securities or property) subject to outstanding Options, and

                      (iii) the exercise price with respect to any Option.

               (b) Subject to Section 7.3(d), in the event of any Corporate
Transaction or other transaction or event described in Section 7.3(a) or any
unusual or nonrecurring transactions or events affecting the Company, any
affiliate of the Company, or the financial statements of the Company or any
affiliate, or of changes in applicable laws, regulations, or accounting
principles, the Committee, in its sole discretion, is hereby authorized to take
any one or more of the following actions whenever the Committee determines that
such action is appropriate in order to prevent dilution or enlargement of the
benefits or potential benefits intended to be made available under the Plan or
with respect to any Option under this Plan, to facilitate such transactions or
events or to give effect to such changes in laws, regulations or principles:

                      (i)  In its sole discretion, and on such terms and 
conditions as it deems appropriate, the Committee may provide, either by the
terms of the applicable Option Agreement or by action taken prior to the
occurrence of such transaction or event and either automatically or upon the
Optionee's request, for either the purchase of any such Option for an amount of
cash equal to the amount that could have been attained upon the exercise of such
Option or realization of the Optionee's rights had such Option been currently
exercisable or the replacement of such Option with other rights or property
selected by the Committee;

                      (ii)  In its sole discretion, the Committee may provide,
either by the terms of the applicable Option Agreement or by action taken prior
to the occurrence of such transaction or event that it cannot be exercised after
such event;

                      (iii) In its sole discretion, and on such terms and 
conditions as it deems appropriate, the Committee may provide, either by the
terms of the applicable Option Agreement or by action taken prior to the
occurrence of such transaction or event, that for a specified period of time
prior to such transaction or event, such Option shall be exercisable as to all
shares covered thereby, notwithstanding anything to the contrary in (A) Section
4.4 or (B) the provisions of the applicable Option Agreement;

                      (iv)  In its sole discretion, and on such terms and 
conditions as it deems appropriate, the Committee may provide, either by the
terms of the applicable Option Agreement or by action taken prior to the
occurrence of such transaction or event, that upon such event, such Option shall
be assumed by the successor or survivor corporation, or a parent or subsidiary
thereof, or shall be substituted for by similar options, rights or awards
covering the stock of the successor or survivor corporation, or a parent or
subsidiary thereof, with appropriate adjustments as to the number and kind of
shares and prices; and

                      (v)  In its sole discretion, and on such terms and 
conditions as it deems appropriate, the Committee may make adjustments in the
number and type of shares of Common Stock (or other securities or property)
subject to outstanding Options and/or in the terms and conditions of (including
the exercise price), and the criteria included in, outstanding Options and
Options which may be granted in the future.

               (c) Subject to Sections 7.3(d) and 7.8, the Committee may, in its
sole discretion, include such further provisions and limitations in any Option
Agreement as it may deem equitable and in the best interests of the Company.

               (d) No adjustment or action described in this Section 7.3 or in
any other provision of the Plan shall be authorized to the extent such
adjustment or action would result in short-swing profits liability under Section
16 of the Exchange Act or violate the exemptive conditions of Rule 16b-3 unless
the Committee determines that the


                                      A-7

<PAGE>   29


Option is not to comply with such exemptive conditions. The number of shares of
Common Stock subject to any Option shall always be rounded to the next whole
number.

               (e) Notwithstanding the foregoing provisions of this Section 7.3,
in the event of any Corporate Transaction the Committee may, in its absolute
discretion and on such terms and conditions as it deems appropriate, also
provide, either by the terms of such Option or by a resolution adopted prior to
the occurrence of such Corporate Transaction each outstanding Option shall,
immediately prior to the effective date of the Corporate Transaction, become
fully exercisable for all of the shares of Common Stock at the time subject to
such Option and may be exercised for any or all of those shares as fully-vested
shares of Common Stock.

        7.4. Approval of Plan by Stockholders. This Plan will be submitted for
the approval of the Company's stockholders within twelve months after the date
of the Board's initial adoption of this Plan. Options may be granted prior to
such stockholder approval, provided that such Options shall not be exercisable
prior to the time when this Plan is approved by the stockholders, and provided
further that if such approval has not been obtained at the end of said
twelve-month period, all Options previously granted under this Plan shall
thereupon be cancelled and become null and void.

        7.5. Tax Withholding. The Company shall be entitled to require payment
in cash or deduction from other compensation payable to each Optionee of any
sums required by federal, state or local tax law to be withheld with respect to
the issuance, vesting or exercise of any Option. The Committee may, in its sole
discretion, allow such Optionee to elect to have the Company withhold shares of
Common Stock otherwise issuable under such Option (or allow the return of shares
of Common Stock) having a Fair Market Value equal to the sums required to be
withheld.

        7.6. Loans. The Committee may, in its sole discretion, extend one or
more loans to key consultants in connection with the exercise of an Option
granted under this Plan. The terms and conditions of any such loan shall be set
by the Committee.

        7.7. Forfeiture Provisions. Pursuant to its general authority to
determine the terms and conditions applicable to Options under the Plan
consistent with the provisions of the Plan, the Committee shall have the right
(to the extent consistent with the applicable exemptive conditions of Rule
16b-3) to provide, in the terms of Options granted under the Plan, or to require
the Optionee to agree by separate written instrument, that (a) any proceeds,
gains or other economic benefit actually or constructively received by the
Optionee upon any receipt or exercise of the Option or upon the receipt or
resale of any Common Stock underlying such Option, must be paid to the Company,
and (b) the Option shall terminate and any unexercised portion of such Option
(whether or not vested) shall be forfeited, if (i) the Optionee incurs a
Termination of Consultancy prior to a specified date, or within a specified time
period following receipt or exercise of the Option, or (ii) the Optionee at any
time, or during a specified time period, engages in any activity in competition
with the Company, or which is inimical, contrary or harmful to the interests of
the Company, as further defined by the Committee.

        7.8. Limitations Applicable to Section 16 Persons and Performance-Based
Compensation. Notwithstanding any other provision of this Plan, the Plan and any
Option granted to any individual who is then subject to Section 16 of the
Exchange Act shall be subject to any additional limitations set forth in any
applicable exemptive rule under Section 16 of the Exchange Act (including any
amendment to Rule 16b-3) that are requirements for the application of such
exemptive rule. To the extent permitted by applicable law, the Plan and Options
granted hereunder shall be deemed amended to the extent necessary to conform to
such applicable exemptive rule.

        7.9. Effect of Plan Upon Options and Compensation Plans. The adoption of
this Plan shall not affect any other compensation or incentive plans in effect
for the Company or any Subsidiary. Nothing in this Plan shall be construed to
limit the right of the Company (a) to establish any other forms of incentives or
compensation for Employees, Directors or consultants of the Company or any
Subsidiary or (b) to grant or assume options or other rights otherwise than
under this Plan in connection with any proper corporate purpose including but
not by way of limitation, the grant or assumption of options in connection with
the acquisition by purchase, lease, merger, consolidation or otherwise, of the
business, stock or assets of any corporation, partnership, firm or association.

Options under this Plan and the issuance and delivery of shares of Common Stock

federal and state laws, rules and regulations (including but not limited to
state and federal securities law and federal margin requirements) and to such
