                         ANNUAL MEETING OF STOCKHOLDERS

                                  INTRODUCTION

        The Annual Meeting of Stockholders of Optical Sensors Incorporated (the
"Company") will be held on Thursday, May 6, 1999, at 3:30 p.m., local time, at
the Hotel Marriott Southwest, 5801 Opus Parkway, Minnetonka, Minnesota, or at
any adjournment or adjournments thereof (the "Annual Meeting"), for the purposes
set forth in the Notice of Meeting.

        A proxy card is enclosed for your use. You are solicited on behalf of
the Board of Directors to SIGN AND RETURN THE PROXY CARD IN THE ACCOMPANYING
ENVELOPE. No postage is required if mailed within the United States. The cost of
soliciting proxies, including the preparation, assembly and mailing of proxies
and soliciting material, as well as the cost of forwarding such material to the
beneficial owners of the Company's common stock, $.01 par value (the "Common
Stock") will be borne by the Company. Directors, officers and regular employees
of the Company may, without compensation other than their regular compensation,
solicit proxies by telephone, telegraph or personal conversation. The Company
may reimburse brokerage firms and others for expenses in forwarding proxy
materials to the beneficial owners of the Common Stock.

        Any stockholder giving a proxy may revoke it at any time prior to its
use at the Annual Meeting either by giving written notice of such revocation to
the Secretary of the Company, by filing a duly executed proxy bearing a later
date with the Secretary of the Company, or by appearing at the Annual Meeting
and filing written notice of revocation with the Secretary of the Company prior
to use of the proxy. Proxies will be voted as specified by stockholders. Proxies
that are signed by stockholders but that lack any such specification will be
voted in favor of the proposals set forth in the Notice of Meeting and in favor
of the election as directors of the nominees for directors listed in this Proxy
Statement.

        THE BOARD RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE APPROVAL OF THE
PROPOSALS SET FORTH IN THE NOTICE OF MEETING.

        The Company expects that this proxy material will first be mailed to
stockholders on or about April 2, 1999.
<PAGE>
 
                                VOTING OF SHARES

        Only holders of the Common Stock of record at the close of business on
March 22, 1999 will be entitled to vote at the Annual Meeting. On March 22,
1999, the Company had 8,841,123 outstanding shares of Common Stock, each such
share entitling the holder thereof to one vote on each matter to be voted on at
the Annual Meeting.

        The presence at the Annual Meeting, in person or by proxy, of the
holders of a majority of the outstanding shares of Common Stock entitled to vote
at the Annual Meeting (4,420,562 shares) will constitute a quorum for the
transaction of business at the Annual Meeting. In general, shares of Common
Stock represented by a properly signed and returned proxy card will be counted
as shares present and entitled to vote at the Annual Meeting for purposes of
determining a quorum, without regard to whether the card reflects abstentions
(or is left blank) or reflects a "broker non-vote" on a matter (i.e., a card
returned by a broker on behalf of its beneficial owner customer that is not
voted on a particular matter because voting instructions have not been received
and the broker has no discretionary authority to vote).

        Holders of shares of Common Stock are not entitled to cumulate voting
rights.

        The election of a nominee for director requires the approval of a
plurality of the shares present and entitled to vote in person or by proxy and
the approval of the other proposals described in this Proxy Statement requires
the approval of a majority of the shares present and entitled to vote in person
or by proxy on that matter (and at least a majority of the minimum number of
votes necessary for a quorum to transact business at the Annual Meeting). Shares
represented by a proxy card including any broker non-votes on a matter will be
treated as shares not entitled to vote on that matter, and thus will not be
counted in determining whether that matter has been approved. Shares represented
by a proxy card voted as abstaining on any of the proposals will be treated as
shares present and entitled to vote that were not cast in favor of a particular
matter, and thus will be counted as votes against that matter.

                              ELECTION OF DIRECTORS

                                   PROPOSAL 1

Nomination

        The Bylaws of the Company provide that the number of directors must be
at least one or such other number as shall be fixed from time to time by
resolution of the Board of Directors. The Board of Directors of the Company (the
"Board") has set its size at six and has nominated the six individuals named
below to serve as directors of the Company until the next annual meeting of
stockholders or until their respective successors have been elected and
qualified. All of the nominees are current members of the Board. Dr. Nicoloff
and Messrs. Humphries, Peterson, Egen and Meelia were elected at the 1998 Annual
Meeting of Stockholders, and Ms. LaPlante was elected by the Board, pursuant to
its authority under the Company's Bylaws to elect directors between stockholder
meetings, in September 1998.

        Assuming a quorum is represented at the Annual Meeting, either in person
or by proxy, the election of each director requires the affirmative vote of a
plurality of the shares of Common Stock represented in person or by proxy at the
Annual Meeting. The Board recommends a vote FOR the election of each of the
nominees listed below. In the absence of other instructions, the proxies will be
voted FOR the election of each of the nominees named below. If prior to the
Annual Meeting, the Board should learn that any nominee will be unable to serve
by reason of death, incapacity or other unexpected

                                       2

occurrence, the proxies that otherwise would have been voted for such nominee
will be voted for such substitute nominee as selected by the Board.
Alternatively, the proxies, at the Board's discretion, may be voted for such
fewer number of nominees as results from such death, incapacity or other
unexpected occurrence. The Board has no reason to believe that any of the
nominees will be unable to serve.

All of the Directors, except Dr. Nicoloff, attended 75% or more of the meetings
of the Board and all such committees on which they served during 1998.

        The Board has established an Audit Committee and a Compensation
Committee. The Audit Committee provides assistance to the Board in satisfying
its fiduciary responsibilities relating to accounting, auditing, operating and
reporting practices of the Company, and reviews the annual financial statements
of the Company, the selection and work of the Company's independent auditors and
the adequacy of internal controls for compliance with corporate policies and
directives. During 1998, the Audit Committee consisted of Mr. Egen and former

options and non-statutory stock options may be granted to eligible key

Director Compensation

        Directors of the Company receive no cash compensation for their services
as members of the Board of Directors, although their out-of-pocket expenses
incurred on behalf of the Company are reimbursed. Prior to October 1995, the
Company's 1993 Stock Option Plan provided for the automatic grant to each
director who is not an employee of the Company an option to purchase 888 shares
of Common Stock on each anniversary of their initial election to the Board,
which became exercisable one year after the date of the grant. On October 3,
1995, this provision in the 1993 Stock Option Plan was terminated and all of the
non-employee directors of the Company were granted an option to purchase 15,555
shares of Common Stock at a price of $2.70 per share. These options become
exercisable, on a cumulative basis, with respect to 25% of the shares covered by
the option, on each of the first four anniversary dates of the grant. In June
1997, each of Messrs. Egen and Meelia were granted an option to purchase 16,000
shares of Common Stock at a price equal to the market value on the date of the
grant. These options become exercisable, on a cumulative basis, with respect to
25% of the shares covered by the option, on each of the first four anniversary
dates of the grant.

        On September 11, 1998, the Company and Sam B. Humphries entered into a
board advisory agreement ("Board Advisory Agreement") that will terminate upon
the earlier of (i) the Company's 1999 Annual Meeting of Stockholders or (ii) May
31, 1999, unless sooner terminated pursuant to the provisions of the Board
Advisory Agreement. Pursuant to the Board Advisory Agreement, Mr. Humphries
provides advice and counsel to the Board of Directors and the President and
Chief Executive Officer of the Company. In consideration for his services, the
Company has agreed to pay Mr. Humphries $50,000 on April 1, 1999.

(1)     All of the options granted to executives were granted under the
        Company's 1993 Stock Option Plan. The foregoing options generally become
        exercisable at the rate of 25% of the number of shares covered by such
        option on each of the first four anniversary dates of the grant of such
        option, so long as the executive remains employed by the Company or one
        of its subsidiaries. However, options granted in November 1998 pursuant
        to the employee repricing program vest beginning on May 6, 1999 at the
        same dates as the corresponding option that was replaced. To the extent
        not already exercisable, options under the plan become immediately
        exercisable in full upon certain changes in control of the Company and
        remain exercisable for the remainder of their term. See "Executive
        Compensation and Other Benefits--Change in Control Arrangements."

        Actual gains, if any, on stock option exercises are dependent upon the
        future performance of the Company's Common Stock, overall market
        conditions and the executive's continued employment with the Company.
        The amounts represented in this table might not necessarily be achieved.

(3)     This option was granted in 1998 and was subsequently canceled and
        reissued in November 1998. See footnote 4 below.

(4)     This option was granted in November 1998 pursuant to the employee
        repricing program and replaced an identical number of previously granted
        options. See "Compensation Committee Report on Repricing of Options."

(5)     This option was granted in March 1998 and expired 90 days after Mr.
        Humphries' resignation on September 11, 1998.

Employment Agreement

        Upon his initial employment in October 1991, the Company entered into an
Employment Agreement with Sam B. Humphries providing for his employment as
President and Chief Executive Officer. During 1998, Mr. Humphries' base salary
was $185,000 per year, and he received an automobile allowance of $500 per
month. In connection with the employment agreement, the Company granted Mr.
Humphries stock options to purchase an aggregate of 121,162 shares of Common
Stock at a price of $9.00 per share, which would have vested at various times
through October 1, 1996. On August 2, 1995, the Board of Directors granted Mr.
Humphries a Non-Statutory Option to purchase 272,222 shares of Common Stock at
an exercise price of $0.90 per share expiring ten years after the grant date,
and canceled Mr. Humphries' prior options. This option was granted as part of a
grant of options to all employees of the Company at the same exercise price. On
September 1, 1995, Mr. Humphries exercised this option and paid for the shares
by executing a non-recourse promissory note in the amount of $245,000 in favor
of the Company, which was secured by a pledge of the shares acquired. Pursuant
to a letter agreement, dated September 14, 1998, Mr. Humphries terminated his
employment with the Company and resigned as an officer effective September 11,
1998. In connection with his resignation, Mr. Humphries forfeited 40,833 shares
of Common Stock of the Company which had not yet vested. The Company forgave
$36,750 of principal under the $245,000 note that Mr. Humphries had executed in
September 1995, and Mr. Humphries repaid the balance of principal and accrued
interest under the note. The Company also made a gross-up payment to Mr.
Humphries of $33,250 to cover income taxes related to the note forgiveness. Mr.
Humphries is prohibited from competing with the Company for a period of one year
following the termination of his employment.

Compensation Committee Report on Repricing Options

        In November 1998, the Compensation Committee repriced existing stock
options held by all employees, including executive officers, by granting new
options at an exercise price of $1.6875 per share in exchange for the
cancellation of previously granted options covering an identical number of
shares that had an exercise price of $2.00 or more. The original options that
were repriced had exercise prices ranging from $3.625 to $13.00 per share. The
$1.6875 exercise price of the repriced options is equal to the fair market value
of one share of Common Stock on November 6, 1998, the date that the repriced
options were granted. The repriced options will expire on March 31, 2008. The
repriced options will vest on May 6, 1999 with respect to the same number of
shares that had vested under the old options on November 6, 1998 and would have
vested between November 7, 1998 and May 6, 1999. Paulita M. LaPlante, the
Company's President and Chief Executive Officer held options to purchase an
aggregate of 288,889 shares, which were repriced to an exercise price of $1.6875
per share. The Compensation Committee and the Board of Directors believed that
repricing the options was critical to retaining the Company's employees,
particularly in light of the fact that the Company was reviewing strategic
alternatives at that time. This review process led to the engagement in December
1998 of Volpe Brown Whelan & Company, LLC, to serve as financial advisor to the
Company. The Company is working with Volpe Brown Whelan to explore strategic
alternatives, including joint ventures, corporate strategic alliances, sale of
the business or product lines, or other business combinations. The Compensation
Committee and the Board believed that providing employees with the opportunity
to benefit from an increase in the equity value of the Company would be a
critical factor in executing the Company's strategic objectives.

Compensation Committee Report on Executive Compensation

        The Compensation Committee consisted of Mr. Peterson and Mr. Meelia
during fiscal 1998. The Compensation Committee makes recommendations to the
Board of Directors concerning the compensation of the Company's directors,
executive officers and key managers, and acts on such other matters relating to
their compensation as it deems appropriate. In addition, the Compensation
Committee administers the Company's stock option plans, pursuant to which
incentive stock options and non-statutory stock options may be granted to
eligible key employees, officers, directors and consultants of the Company, and
the Company's Employee Stock Purchase Plan, pursuant to which employees of the
Company may purchase shares of Common Stock directly from the Company on
favorable terms through payroll deductions.

        Compensation Philosophy and Objectives. The philosophy underlying the
decisions and recommendations of the Compensation Committee is to recognize and
reward results and achievement at the Company and individual level by linking
compensation to such achievement. Consistent with this philosophy, the
Compensation Committee has set the following objectives for the Company's
executive compensation program:

        o       Motivate officers to achieve desired Company performance goals
                by rewarding such achievements.

        o       Provide a program of compensation that is competitive with
                comparable companies to enable the Company to attract and retain
                key executive talent.

        o       Align the interests of the Company's executives with the
                interests of the Company's stockholders by linking compensation
                to the Company's performance and by providing the Company's
                executives with long-term opportunities for stock ownership.

        In determining its recommendations as to the compensation of the
Company's executives, the Compensation Committee considers factors such as
Company performance, both in isolation and in comparison to companies of
comparable development, complexity and size; the individual performance of each
executive officer; historical compensation levels at the Company; the overall
competitive environment for executives and the level of compensation necessary
to attract and retain the level of key executive talent desired by the Company.
The Compensation Committee places primary emphasis on Company performance rather
than individual performance as measured against goals approved by the
Compensation Committee. In analyzing these factors, the Compensation Committee
may from time to time review competitive compensation data gathered in
comparative surveys or collected by independent consultants.

        Executive Compensation Program Components. The Company's executive
compensation program consists of base salary, annual cash performance bonuses,
and long-term incentive opportunities under the Company's stock option plans.
Each element of the compensation program is discussed in greater detail below.

                Base Salary. The Compensation Committee's recommendations
        regarding the base salary of each executive officer of the Company,
        including the compensation of Ms. LaPlante as President and Chief
        Executive Officer, are based on a number of factors, including the
        executive officer's experience and qualifications, the potential impact
        of the individual on the Company's performance, the level of skill and
        responsibility required by the individual's position and the other
        factors described above. Base salaries are determined for each year
        prior to the beginning

                                       13
<PAGE>
 
        of the year. In general, the Compensation Committee seeks to set
        executive officer base salaries at moderately to aggressively
        competitive levels in relation to the companies with which the Company
        competes for executives. In September 1998, Ms. LaPlante's base salary
        was increased from $121,000 to $180,000 in connection with her
        appointment as President of the Company.

                Annual Management Performance Bonuses. The Company's annual
        management performance bonus program is designed to provide a direct
        financial incentive to the Company's executive officers, including the
        President and Chief Executive Officer, for the achievement of specific
        Company performance goals. Following Ms. LaPlante's appointment in
        September 1998 as the Company's President, the Compensation Committee,
        with input from Ms. LaPlante, established performance goals, with a
        bonus of $50,000 if the minimum objectives were met and $75,000 if the
        maximum objectives were met. These objectives included achievement of
        specified sales quotas, the reorganization of the Company to meet
        specified spending goals, identification of potential corporate partners
        and funding sources, identification and retention of leading investment
        banking firms, and retention of key personnel necessary for
        implementation of the CapnoProbe program. The Committee concluded that
        Ms. LaPlante achieved all of the objectives. Accordingly, in the first
        quarter of 1999, Ms. LaPlante was paid a bonus of $75,000 for 1998. No
        bonus plan was established for, nor were any bonuses paid to, any of the
        other officers of the Company for 1998.

                Long-Term Incentive Compensation. The Compensation Committee
        makes long-term incentive compensation available to the Company's
        executive officers, as well as all other employees of the Company,
        through the grant of stock options. The purpose of stock option grants
        is to advance the interests of the Company and its stockholders by
        enabling the Company to attract and retain persons of ability to perform
        services for the Company, including persons performing services to the
        Company as executive officers. By granting stock options to executive
        officers and other employees, the Compensation Committee seeks to align
        the long-term interests of these individuals with those of the Company's
        stockholders by creating a strong and direct nexus between compensation
        and stockholder return and to enable executive officers and key managers
        to develop and maintain a significant ownership position in the Company.
        The Compensation Committee determines the number of options and the
        terms and conditions of such options based on certain factors, including
        the past performance of the executive officer, the executive officer's
        potential impact on the achievement of the Company's objectives, past
        grants or awards of stock-based compensation and on comparative
        compensation data regarding option grants by Company's within the
        medical device industry as well as within a broader group of companies
        of comparable size and complexity. Additionally, options may be granted
        to an executive officer as an incentive at the time the executive
        officer joins the Company. All options granted by the Compensation
        Committee have an exercise price equal to 100% of the fair market value
        of the Common Stock on the date of grant. In general, options vest at
        the rate of 25% of the shares covered by the option each year over a
        period of four years and remain exercisable for a period of 10 years
        from the date of grant, provided the individual continues to be employed
        by the Company. In 1998, the Compensation Committee granted options to
        all executive officers of the Company and key managers and sales
        personnel of the Company. The primary purpose of the 1998 stock option
        grants was to recognize the outstanding individual contributions being
        made by these individuals during a year in which the Company would
        likely not meet its sales or financial objectives. In September 1998,
        Ms. LaPlante was granted an option covering 200,000 shares of Common
        Stock in connection with her appointment as President of the Company. In
        addition, in November 1998, the Compensation Committee repriced stock
        options held by all

                                       14
<PAGE>
 
        employees that had an exercise price of $2.00 per share or more. See
        "Compensation Committee Report on Repricing of Options."

        Section 162(m). Section 162(m) of the Internal Revenue Code of 1986, as
amended (the "Code"), limits the deductibility of certain compensation paid to
the chief executive officer and each of the four other most highly compensated
executives of a publicly held corporation to $1,000,000. In 1998, the Company
did not pay "compensation" within the meaning of Section 162(m) to such
executive officers in excess of $1,000,000, and does not believe it will do so
in the near future. Therefore, the Company does not have a policy at this time
regarding qualifying compensation paid to its executive officers for
deductibility under Section 162(m), but will formulate such a policy if
compensation levels ever approach $1,000,000.

Comparative Stock Performance

        The graph below compares, for the period from February 14, 1996, the
date of the Company's initial public offering, to December 31, 1998, the total
cumulative stockholder return on the Company's Common Stock to the total
cumulative return on the Standard & Poor's 500 Stock Index and a peer-group
selected in good faith by the Company consisting of the following companies:
Datascope Corporation; Diametrics Medical, Inc.; i-Stat Corporation; Marquette
Medical Systems, Inc.; Protocol Systems, Inc.; and Spacelabs Medical, Inc. The
peer group consists of public companies in the Company's industry that market
arterial blood gas measurement systems or critical care patient bedside
monitoring systems, and the peer-group companies were selected on that basis.
The graph assumes a $100 investment in the Company's Common Stock, the Standard

Change in Control Arrangements

        In January 1998, the Company's Board of Directors approved a change in
control severance pay plan (the "Change in Control Plan") for the Company's
executive officers (the "Executives"). All of the Company's executive officers
are covered by the Change in Control Plan. The Change in Control Plan provides
for the payment of certain benefits to Executives of the Company upon the
occurrence of a "Partial Change in Control" or a "Full Change in Control" A
Partial Change in Control is defined as: (i) the sale of either the SensiCath
product line or the CapnoProbe product line, but not both, or (ii) cessation of
commercial activity or liquidation of the SensiCath product line. In January
1999, the Company suspended direct sales activity of the SensiCath product line
and implemented a significant workforce reduction. This action constituted a
Partial Change in Control under the Change in Control Plan. A Full Change in
Control is defined as: (i) a merger involving the Company where the pre-merger
Company's stockholders own (solely as a result of ownership before the merger of
the Company stock) at least 50% but less than 80% of the surviving Company's
voting stock (unless approved by the Board of Directors) or less than 50% of the
surviving company's voting stock (whether or not approved by the Board of
Directors); (ii) a transfer of substantially all of the Company's assets or
liquidation of the Company; (iii) ownership by any person or group of 20% to 50%
of the Company's voting stock (unless approved by the Board of Directors) or
more than 50% of the Company's voting stock (whether or not approved by the
Board of Directors); (iv) the "continuity" directors (the Company's current
directors and their future nominees) cease to constitute a majority of the Board
of Directors; and (v) any change of control that would be required by the
Securities and Exchange Commission to be reported. In either case benefits are
conditioned on termination of employment.

        An Executive will become eligible for benefits under the Change in
Control Plan if the Executive is terminated by the Company without "cause"
within 12 months after a Partial Change in Control or a Full Change in Control.
In addition, an Executive will become eligible for benefits if the Executive
terminates his or her employment for "good reason" within 12 months after a Full
Change in Control. Good reason includes adverse changes in the Executive's
status or position, reduction in base salary, material adverse changes in
benefit plans and relocation. In the case of termination following a Partial
Change in Control, the Executive will receive a cash payment equal to 100% of
his or her annual base pay, payable over the twelve-month period following
termination. If a Full Change in Control occurs prior to full payment, the
remaining balance will be paid in a lump-sum at the time of the Full Change in
Control. In the case of termination following a Full Change in Control, the
Executive will receive a lump-sum cash payment equal to 100% of his or her
annual base pay. In the case of termination following a Partial or Full Change
in Control, the Executive will receive continued coverage under group health
plan for 12 months at the rate for active employees (followed by 18 months of
required "COBRA" coverage solely at the Executive's expense). In addition, if
the Executive is terminated by the Company without "cause" within 12 months
after a Partial Change in Control, all options held by the Executive will remain
exercisable, to the extent exercisable at the time of termination, until their
expiration date. In addition if a Full Change in Control occurs after the
Executive's termination, his or her options will automatically accelerate and be
exercisable in full. If any payments to the Executive in connection with a
change in control (including acceleration of stock options) are subject federal
excise tax on "excess parachute payments, the Executive will also receive a
"gross up" payment sufficient to pay any excise tax on "excess parachute
payments."

        The Change in Control Plan cannot be amended or terminated in any way
adversely affecting participants within the one year period before a change in
control without the participant's consent.

        Under the Company's 1993 Stock Option Plan, as amended (the "1993
Plan"), upon the occurrence of a "change in control" all outstanding options
granted under the 1993 Plan will become and remain exercisable in full during
their remaining terms regardless of whether the plan participants

                                       16
<PAGE>
 
thereafter remain employees of the Company or a subsidiary. The acceleration of
the exercisability of options under the 1993 Plan may be limited, however, if
the acceleration would be subject to an excise tax imposed upon "excess
parachute payments." Under the 1993 Plan, a "change in control" has occurred in
the event of (a) the sale, lease, exchange or other transfer of all or
substantially all of the assets of the Company (in one transaction or in a
series of related transactions) to a corporation that is not controlled by the
Company; (b) the approval by the stockholders of the Company of any plan or
proposal for the liquidation or dissolution of the Company; (c) a change in
control of the Company of a nature that would be required to be reported
pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as
amended, whether or not the Company is then subject to such reporting
requirement; (d) any person becomes the "beneficial owner," directly or
indirectly, of 50% or more of the combined voting power of the Company's
outstanding securities ordinarily having the right to vote at elections of
directors; or (e) individuals who constitute the board of directors of the
Company on the effective date of the 1993 Plan cease for any reason to
constitute at least a majority thereof, provided that any person becoming a
director subsequent to the effective date of the 1993 Plan whose election, or
nomination for election by the Company's stockholders, was approved by a vote of
at least a majority of the directors comprising the board of directors of the
Company on the effective date of the 1993 Plan (either by a specific vote or by
approval of the proxy statement of the Company in which such person is named as
a nominee for director, without objection to such nomination) shall be
considered as though such person were a member of the board of directors of the
Company on the effective date of the 1993 Plan. In addition, the Compensation
Committee, with the consent of any affected participant, may determine that some
or all of the participants holding outstanding options will receive cash in an
amount equal to the excess of the fair market value of such shares immediately
before the effective date of the change in control over the exercise price per
share of the options.


                          RATIFICATION OF SELECTION OF
                              INDEPENDENT AUDITORS

                                   PROPOSAL 2


        The Board of Directors has appointed Ernst & Young LLP, independent
certified public accountants, as auditors of the Company for the year ending
December 31, 1999. Such firm has acted as independent auditors of the Company
since the fiscal year ended December 31, 1989. Although it is not required to do
so, the Board wishes to submit the selection of Ernst & Young LLP to the
stockholders for ratification. If the stockholders do not ratify the appointment
of Ernst & Young LLP, another firm of independent auditors will be considered by
the Board of Directors. Representatives of Ernst & Young LLP will be present at
the Annual Meeting, will have an opportunity to make a statement if they so
desire and will be available to respond to appropriate questions.

Board of Directors Recommendation

        The Board of Directors recommends a vote FOR ratification of the
appointment of Ernst & Young LLP as auditors of the Company for the year ending
December 31, 1999. The affirmative vote of the holders of a majority of shares
of Common Stock of the Company present in person or by proxy at the Annual
Meeting, assuming a quorum is present, is necessary for approval. Unless a
contrary choice is specified, proxies solicited by the Board of Directors will
be voted FOR the ratification of Ernst & Young LLP.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

        Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act") requires the Company's directors and executive officers and all
persons who beneficially own more than 10% of the outstanding shares of the
Company's Common Stock to file with the Securities and Exchange Commission
initial reports of ownership and reports of changes in ownership of the
Company's Common Stock. Executive officers, directors and greater than 10%
beneficial owners are also required to furnish the Company with copies of all
Section 16(a) forms they file. To the Company's knowledge, based upon a review
of the copies of such reports furnished to the Company during the year ended
December 31, 1998 and written representations by such persons, all of the
directors, officers and beneficial owners of greater than 10% of the Company's
Common Stock filed on a timely basis the forms required by Section 16 of the
Exchange Act, except that Gary A. Peterson, a director of the Company, filed a
Form 4 in January 1999 reporting the sale of shares of Common Stock in December
1998 after the date such report was required to be filed.


                  STOCKHOLDER PROPOSALS FOR 2000 ANNUAL MEETING

of Stockholders without including the proposal in the Company's proxy statement

notice by this date, then the persons named as proxies in the proxies solicited

                                  OTHER MATTERS

        The management of the Company does not intend to present other items of
business and knows of no items of business that are likely to be brought before
the Annual Meeting except those described in this Proxy Statement. However, if
any other matters should properly come before the Annual Meeting, the persons
named in the enclosed proxy will have discretionary authority to vote such proxy
