            PROXY STATEMENT FOR 1998 ANNUAL MEETING OF STOCKHOLDERS
                 INFORMATION CONCERNING SOLICITATION AND VOTING
 
GENERAL
 
    The enclosed proxy is solicited on behalf of Advanced Energy Industries,
Inc., a Delaware corporation (the "Company"), for use at the Annual Meeting of
Stockholders (the "Annual Meeting") to be held on Wednesday, May 6, 1998 at
10:00 a.m., local time, or at any adjournment thereof, for the purposes set
forth herein and in the accompanying Notice of Annual Meeting Of Stockholders.
The Annual Meeting will be held at the Company's executive offices at 1625 Sharp
Point Drive, Fort Collins, Colorado 80525. The Company's telephone number is
(970) 221-4670.
 
    These proxy solicitation materials, together with a copy of the Company's
1997 Annual Report to Stockholders, were mailed on or about April 2, 1998 to all
stockholders entitled to vote at the meeting.
 
RECORD DATE AND PRINCIPAL SHARE OWNERSHIP
 
    Stockholders of record at the close of business on March 9, 1998 (the
"Record Date") are entitled to receive notice of and to vote at the Annual
Meeting. On the Record Date, 22,517,438 shares of the Company's Common Stock,
$0.001 par value (the "Common Stock"), were issued and outstanding.
 
REVOCABILITY OF PROXIES
 
    Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before its use by delivering to the Company a written
notice of revocation or a duly executed proxy bearing a later date or by
attending the Annual Meeting and voting in person. Attending the Annual Meeting
in and of itself may not constitute a revocation of a proxy.
 
VOTING AND SOLICITATION
 
    Each share of Common Stock entitles its holder to one vote on matters to be
acted upon at the Annual Meeting. Votes cast by proxy or in person at the Annual
Meeting will be tabulated by the Inspector of Elections (the "Inspector") with
the assistance of the Company's transfer agent. The Inspector will also
determine whether or not a quorum is present. The affirmative vote of a majority
of shares present in person or represented by proxy at a duly held meeting at
which a quorum is present is required under Delaware law for approval of
proposals presented to stockholders. In general, Delaware law also provides that
a quorum consists of a majority of the shares entitled to vote and present or
represented by proxy at the meeting. The Inspector will treat abstentions as
shares that are present and entitled to vote for purposes of determining the
presence of a quorum but will not treat abstentions as votes in favor of
approving any matter submitted to the stockholders for a vote. Any proxy which
is returned using the form of proxy enclosed and which is not marked as to a
particular item will be voted for the election of directors, for ratification of
the appointment of the designated independent auditors, for amendments of the
Plan (defined herein) as set forth herein, and, as the case may be with respect
to any items not marked, as the proxy holders deem advisable, on any other
matters that may come before the meeting. If a broker indicates on the enclosed
proxy or its substitute that it does not have discretionary authority as to
certain shares to vote on a particular matter ("broker non-votes"), those shares
will not be considered as present with respect to that matter. The Company
believes that the tabulation procedures to be followed by the Inspector are
consistent with the general statutory requirements in Delaware concerning voting
of shares and determination of a quorum.
 
    The cost of soliciting proxies will be borne by the Company. The Company has
retained the services of the Bank of Boston NA, c/o Boston Equiserve LP to aid
in the solicitation of proxies from bankers, bank
 
                                       1
<PAGE>
nominees and other institutional owners. The Company estimates that it will pay
the Bank of Boston a fee not to exceed $2,500 for its services and will
reimburse the Bank of Boston for certain out-of-pocket expenses. The Company may
reimburse brokerage firms and other persons representing beneficial owners of
shares for their expenses in forwarding solicitation materials to such
beneficial owners. Proxies may also be solicited by certain of the Company's
directors, officers and regular employees, without additional compensation,
personally or by telephone, telefax, or telegram.
 
                                 PROPOSAL NO. 1
                             ELECTION OF DIRECTORS
 
NOMINEES
 
    A board of six directors is to be elected at the Annual Meeting. The proxies
cannot be voted for a greater number of persons than six. Unless otherwise
instructed, the proxy holders will vote the proxies received by them for the
Company's six nominees named below, all of whom are presently directors of the
Company. In the event that any nominee of the Company is unable or declines to
serve as a director at the time of the Annual Meeting, the proxies will be voted
for any nominee who shall be designated by the present Board of Directors to
fill the vacancy. The Company is not aware of any nominee who will be unable or
will decline to serve as a director. The term of office of each person elected
as a director will continue until the next Annual Meeting of Stockholders or
until a successor has been elected and qualified.
 
    The following table sets forth certain information concerning the nominees
which is based on data furnished by them.

and was appointed to the Company's Audit Committee and Compensation Committee,
to fill the vacancy on the Board and the committees created by the resignation
of Mr. Jon Tompkins. In June 1997, Mr. Caswell was appointed Chief Operating
Officer of the Company and, because he then ceased to be an outside director, he
resigned his membership on the two committees. In July 1997, Arthur A. Noeth was
elected to the Board of Directors and appointed to the two committees.
 
    The Board of Directors of the Company held a total of six meetings,
including one telephonic meeting, during the fiscal year ended December 31,

meetings of the committee or committees on which he served in 1997.

of Messrs. Spedden and Tompkins. The Audit Committee currently consists of
Messrs. Spedden and Noeth and is responsible for recommending engagement of the
Company's independent auditors, reviewing the scope of the audit, considering
the comments made by the independent auditors with respect to accounting
procedures and internal controls and the consideration given thereto by the
Company management, and reviews the internal accounting procedures and controls
with the Company's financial and accounting staff.
 
    The Compensation Committee met once in 1997. At that time such committee
consisted of Messrs. Spedden and Noeth. The Compensation Committee recommends

                             DIRECTOR COMPENSATION
 
    Directors who are not employees of the Company receive meeting fees of
$3,000 for each Board of Directors meeting attended, other than telephonic
meetings, and $300 for each committee meeting attended, plus reimbursement for
reasonable out-of-pocket travel expenses. In addition, each person who is a
non-employee director is automatically granted upon becoming a director of the
Company an option to purchase 7,500 shares of the Company's Common Stock under
the Company's 1995 Non-Employee Directors' Stock Option Plan (the "Directors'
Plan") at a price per share equal to the fair market value of one share of the
Company's Common Stock on that date. Each option has a term of ten years and is
immediately exercisable as to 2,500 shares of Common Stock, and vest as to 2,500
shares of Common Stock on each of the second and third anniversaries of the
grant date. On each anniversary of the date on which a person becomes a
non-employee director, an option for an additional 2,500 shares will be granted
under the Directors' Plan to such director. Such additional options vest in full
on the third anniversary of the grant date and expire ten years after the grant
date. The exercise price of such options is equal to the fair market value of
the Common Stock on the respective grant date. 50,000 shares of Common Stock
have been reserved for issuance pursuant to options to be granted under the
Directors' Plan. As of March 15, 1998, options to purchase a total of 7,500
shares were outstanding under the Directors' Plan.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The current members of the Compensation Committee are Elwood Spedden and
Arthur Noeth. Prior to Mr. Noeth, Hollis Caswell was a member of the
Compensation Committee until he became Chief Operating Officer in June 1997.
Prior to Mr. Caswell, Jon Tompkins was a member of the Compensation Committee
until he resigned in February 1997. Other than Mr. Caswell none of such persons
is or has been an officer or employee of the Company or any of its subsidiaries,
nor has any of such persons had a direct or indirect interest in any business
transaction with the Company which involved an amount in excess of $60,000. None
of the executive officers of the Company has served as a member of the board of
directors or on the compensation committee of any other company of which any
member of the Compensation Committee during 1997 is or has been an executive
officer.
 
                        REPORT ON EXECUTIVE COMPENSATION
 
    The Compensation Committee, which consists of two non-employee directors,
reviews and makes recommendations with respect to the Company's executive
compensation policies and the compensation to be paid to each of the executive
officers. The recommendations of the Compensation Committee with respect to each
executive officers' compensation are subject to approval by the Board of
Directors. The Committee also reviews the compensation policy, particularly with
respect to stock options, for key managers who are not corporate officers.
 
COMPENSATION POLICIES
 
    One of the primary goals in setting compensation policies is to maintain
competitive, progressive programs to attract, retain and motivate high caliber
executives, foster teamwork and maximize the long-term success of the Company by
appropriately rewarding such individuals for their achievements. Another goal is
to provide an incentive to executives to focus efforts on long-term strategic
goals for the Company by closely aligning their financial interests with
stockholder interests. To attain these goals the Company's executive
compensation program was designed to include base salary, annual incentives and
long-term incentives.
 
                                       8
<PAGE>
    In formulating and administering the individual elements of the Company's
executive compensation program, planning, implementing and achieving long-term
objectives are emphasized to establish performance objectives, evaluate
performance and determine actual incentive awards.
 
COMPENSATION COMPONENTS
 
BASE SALARY
 
    The base salaries of executive officers were established after review of
relevant data of other executives with similar responsibilities from published
industry reports and surveys of similarly situated companies. The objective is
to maintain the Company's annual executive salaries at levels competitive with
the market average base salary of executive officers in similar positions. The
market is comprised of similarly sized high technology companies within and
outside the Company's industry. In 1998, a large portion of each executive
officer's compensation will be in the form of a cash bonus, provided certain
target performance objectives are met. The Compensation Committee has
established base salary and incentives for the executive officers for 1998.
 
ANNUAL INCENTIVES
 
    The more aggressive incentive bonus levels for executives are intended to
provide the appropriate elements of variability and risk. Bonus payments are
tied specifically to targeted corporate performance. The Committee will
establish a base bonus amount, determined through review of a competitive market
survey for executives at similar levels, which will be incrementally reduced if
the Company does not meet its targeted performance or increased if the Company
exceeds its targeted performance. There is no minimum or maximum percentage by
which the bonus can be reduced or increased.
 
STOCK OPTIONS
 
    The Committee will grant stock options under the Company's 1995 Stock Option
Plan to focus the executive's attention on the long-term performance of the
Company and on maximizing stockholder value. The grant of stock options is
closely tied to individual executive performance. The Committee will grant such
stock options after a review of various factors, including the executive's
potential contributions to the Company, current equity ownership in the Company
and vesting rates of existing stock options, if any. Incentive stock options and
non statutory stock options are granted with an exercise price of at least 100%
and 85%, respectively, of the fair market value of the Common Stock subject to
the option on the date of the grant and utilize vesting periods to encourage
retention of executive officers. Because of the direct benefit executive
officers receive through improved stock performance, the Committee believes
stock options serve to align the interests of executive officers closely with
those of other stockholders.
 
COMPENSATION OF CHIEF EXECUTIVE OFFICER
 
    The compensation of the Chief Executive Officer, Mr. Douglas S. Schatz, was
based on the policies and procedures described above. In determining Mr.
Schatz's base salary and bonus, compensation levels for other chief executive
officers in high technology firms within and outside the industry were examined.
This information was compared to the relevant performance of such firms relative
to the Company's performance.
 
EFFECT OF SECTION 162(M) OF THE INTERNAL REVENUE CODE
 
    Section 162(m) of the Internal Revenue Code of 1986 (the "Code") generally
limits the corporate deduction for compensation paid to certain executive
officers to $1 million, unless the compensation is performance based. The Board
has carefully considered the potential impact of this tax code provision on the
Company and has concluded in general that the best interests of the Company and
the stockholders will be served if certain of the Company's stock-based
long-term incentives qualify as performance-based
 
                                       9
<PAGE>
compensation within the meaning of the Code. It is the Board's intention that,
so long as it is consistent with its overall compensation objectives, virtually
all executive compensation will be deductible for federal income tax purposes.

                              CERTAIN TRANSACTIONS
 
    The Company's executive offices and manufacturing facilities in Fort
Collins, Colorado are leased from Prospect Park East Partnership and from Sharp
Point Properties, LLC, (a Colorado limited liability company, the "LLC"), in
which Douglas S. Schatz, President, Chief Executive Officer and Chairman of the
Board of the Company, and G. Brent Backman, Vice President, Special Projects of
the Company, hold
 
                                       10
<PAGE>
26.67% and 6.66% member interests, respectively, in each of the leasing
entities. The Company believes that the terms of such leases are no less
favorable than could have been obtained from a third party lessor. Aggregate
rental payments under such leases for 1997 totaled approximately $1,320,834. The
Company leases a condominium in Breckenridge, Colorado owned by a partnership
formed by Messrs. Schatz and Backman. The Company uses the condominium to
provide rewards and incentives to its customers, suppliers and employees. The
Company believes that the terms of such lease are no less favorable than could
have been obtained from a third party lessor. Aggregate rental payments under
such lease for 1997 totaled $36,000.
 
                                 PROPOSAL NO. 2
                      AMENDMENT OF 1995 STOCK OPTION PLAN
 
    The Compensation Committee of the Board of Directors of the Company (the
"Committee"), the administrator of the Company's 1995 Stock Option Plan (the
"Plan"), has amended the Plan to increase the number of shares of Common Stock
issuable thereunder from 3,500,000 to 4,625,000 (the "Amendment"). The Amendment
was ratified by the Board of Directors of the Company on February 10, 1998 and
is subject to approval of the stockholders. Technical amendments to reflect
certain changes in the tax and securities laws also were approved by the
Committee and ratified by the Board of Directors. A copy of the Plan, as
revised, may be obtained from the Plan Administrator at the Company's corporate
offices at 1625 Sharp Point Drive, Fort Collins, Colorado 80525; telephone
number: 970-221-4670.
 
    OVERVIEW
 
    The stated purposes of the Plan are to provide a means by which the Company
can seek to retain the services of its existing employees and directors, to
secure and retain the services of new employees, directors and consultants and
to provide incentives for such persons to exert maximum efforts for the success
of the Company and its affiliates.
 
    Options to purchase Common Stock ("Options") may be issued under the Plan to
any person, including an officer or director, employed by the Company or an
affiliate of the Company, or to any person, including an advisor, who is engaged
by the Company or an affiliate of the Company to render consulting services,
provided that such person is compensated for such services ("Eligible
Optionees"). When the Plan was first adopted in 1993, approximately 250 persons
were Eligible Optionees. As of December 31, 1997, approximately 575 persons were
Eligible Optionees. In addition to this growth in the Company, and the resulting
issuance of Options to Eligible Optionees, certain officers of the Company
elected in 1996 to receive Options in lieu of a portion of their salary for that
year.
 
    As of February 1, 1998, the Company had issued 1,998,673 shares of Common
Stock pursuant to Options and Options to purchase an additional 1,481,034 shares
of Common Stock were outstanding under the Plan. The Company desires to amend
the Plan to increase the number of shares of Common Stock issuable thereunder
because the Company believes that Options are a critical component of its
employees' compensation.
 
    THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS A VOTE "FOR" AMENDMENT OF
THE 1995 STOCK OPTION PLAN TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK
ISSUABLE THEREUNDER FROM 3,500,000 TO 4,625,000
 
CERTAIN INFORMATION REGARDING THE PLAN
 
    The Committee has the power to determine from time to time the Eligible
Optionees to be granted Options, as well as the power to determine the terms and
conditions of such Options. The Committee may amend or terminate the Plan at any
time and for any reason, subject to ratification by the board of directors, any
required regulatory approval and any required approval of the stockholders of
the Company.
 
                                       11
<PAGE>
    DESCRIPTION OF OPTIONS.  The provisions of separate Options need not be
identical, but each Option is subject to the following provisions: (a) the term
of any Option may not be longer than ten (10) years from the date of grant, (b)
the exercise price of an Incentive Stock Option (as defined in the 1995 Stock
Option Plan) shall not be less than 100% of the fair market value of the
underlying Common Stock, and the exercise price of a Nonstatutory Stock Option
(as defined in the 1995 Stock Option Plan) shall not be less than 85% of the
fair market value of the underlying Common Stock, and (c) an Option shall not be
transferable except by will or by the laws of descent and distribution; provided
that a Nonstatutory Stock Option may also be transferred pursuant to a qualified
domestic relations order satisfying the requirements of Rule 16b-3 under the
Exchange Act.
 
    EXERCISE OF OPTIONS.  Payment of the exercise price of an Option must be
made either (i) in cash at the time the Option is exercised, or (ii) at the
discretion of the Committee, either at the time of the grant or exercise of the
Option, (A) by delivery to the Company of other shares of Common Stock, (B)
according to a deferred payment or other arrangement (which may include the use
of other shares of Common Stock) with the optionee or a permitted transferee, or
(C) in any other form of legal consideration that may be acceptable to the Board
of Directors of the Company.
 
    ALLOCATION OF EMPLOYEE OPTIONS IN 1998.  The potential benefit to be
received by an optionee is dependent on increases in the price of the Common
Stock prior to exercise of the Option. Accordingly, the ultimate dollar value of
the Options is not currently ascertainable. As of March 9, 1998, the closing
price of the Common Stock on the Nasdaq was $15.125.
 
    The Compensation Committee has granted to certain officers of the Company
Options that are subject to the stockholders' approval of the Amendment
("Contingent Options"). If the Amendment is not approved by the stockholders,
the Contingent Options will be cancelled without any additional action by the
Company, the Committee or the holders of the Contingent Options. The following
table sets forth certain information as of the date hereof with respect to
Options granted in 1998, including the Contingent Options.

    All of the options were granted under the Company's 1995 Stock Option Plan.
Each option vests as to one fourth of the underlying shares on the first
anniversary of its grant date and as to an additional one sixteenth each quarter
thereafter until fully vested except for Mr. Beck whose options vest quarterly
at the rate of one sixteenth each quarter from the date of grant. The exercise
price of each of the foregoing options is equal to the closing price of the
Common Stock, as reported on the Nasdaq National Market, on the grant date.
 
    If the Amendment is approved by the stockholders, the Compensation Committee
intends to grant additional Options under the Plan in 1998. However, the number
of Options to be granted and the
 
                                       12
<PAGE>
allocation among the persons set forth in the table above will be determined by
the Committee in its discretion and, accordingly, are not currently
determinable.
 
    UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS.  The following is a summary
of the principal anticipated United States federal income tax considerations of
the grant and exercise of an Option to and by an Eligible Optionee who is
resident in the United States. It is based on the current provisions of the
Internal Revenue Code of 1986, as amended, and the rules and regulations
thereunder (the "Current Tax Rules"). This discussion is general only and is not
a substitute for independent advice from an individual's own tax and other
advisors.
 
    GRANT OF OPTIONS.  An optionee will not recognize any taxable income at the
time an Option is granted.
 
    EXERCISE OF NONSTATUTORY STOCK OPTIONS.  Upon exercise of a Nonstatutory
Stock Option, an optionee generally will recognize ordinary income, for United
States income tax purposes, equal to the excess, if any, of the then fair market
value of the Common Stock acquired ("NSO Stock") over the exercise price of the
Option. Any taxable income recognized in connection with the exercise of a
Nonstatutory Stock Option generally will be subject to tax withholding by the
Company, and the Company generally will be entitled to United States income tax
deductions to the extent and in the year that such taxable income is recognized
by the optionee.
 
    EXERCISE OF INCENTIVE STOCK OPTIONS.  Upon exercise of an Incentive Stock
Option, an optionee will not recognize taxable income if the optionee (a) does
not dispose of the Common Stock so acquired ("ISO Stock") within two years after
the date the Option is initially granted or one year after the date of exercise
(collectively, the "Holding Periods"), and (b) is an employee of the Company or
an affiliate of the Company from the date the Option is initially granted until
three months prior to the date of exercise of the Incentive Stock Option
(together, the "ISO Requirements"). If the ISO Requirements are met, the basis
of the ISO Stock will be the price paid by the optionee on exercise of the
Option. If the market value of the ISO Stock on the exercise date of the Option
is greater than the exercise price of such Option, the difference between such
amounts would be an item of tax preference, potentially subject to alternative
minimum tax. If the ISO Requirements are met, the Company will not be entitled
to any United States income tax deductions with respect to the exercise of
Incentive Stock Options.
 
    DISPOSITION OF COMMON STOCK.  When an optionee sells NSO Stock, any
difference between the sale price and the optionee's tax basis in the NSO Stock
will be treated as capital gain or loss. When an optionee sells ISO Stock, any
difference between the sale price and the optionee's tax basis in the ISO Stock
will be taxed as long-term capital gain.
 
    If an optionee disposes of ISO Stock prior to expiration of either of the
Holding Periods, the optionee will recognize ordinary income, and the Company
will be entitled to a tax deduction, equal to the lesser of (i) the fair market
value of the ISO Stock on the exercise date less the exercise price of the
related Option, and (ii) the amount realized on disposition of the ISO Stock
minus the exercise price of the related Option. Any gain realized in excess of
the ordinary income portion would be taxable as long-term or short-term capital
gain, as applicable.
 
    CAPITAL GAINS.  For dispositions of NSO Stock or ISO Stock occurring after
July 28, 1997, long term capital gains will be taxed at a rate of 10% (for
persons in the 15% tax bracket) or 20% (for other individuals) if the stock is
held for more than 18 months from the exercise date. A rate of 28% will apply in
the case of Common Stock held more than one year from the exercise date but not
more than 18 months.
 
    DIVIDENDS.  Dividends payable on Common Stock out of earnings and profits of
the Company are ordinary income taxable at ordinary income rates.

                                 PROPOSAL NO. 3
              RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS
 
    Unless marked to the contrary, proxies received will be voted "FOR" the
ratification of the appointment of Arthur Andersen LLP as the independent
auditors for the Company for the current year. Arthur Andersen LLP has been the
Company's independent auditors since 1994. If the stockholders fail to ratify
the appointment of Arthur Andersen LLP, the Board of Directors will reconsider
its selection.
 
    Audit services of Arthur Andersen LLP during the 1997 fiscal year included
the examination of the consolidated financial statements of the Company and
services related to filings with the Securities and Exchange Commission ("SEC")
and other regulatory bodies.
 
    The Audit Committee of the Company will meet with Arthur Andersen LLP on an
annual or more frequent basis. At such time the Audit Committee will review the
services performed by Arthur Andersen LLP for the preceding year, as well as the
fees charged for such services.
 
    A representative of Arthur Andersen LLP is expected to be present at the
Annual Meeting and will have an opportunity to make a statement if he or she so
desires. Moreover, the representative is expected to be available to respond to
appropriate questions from the stockholders.
 
    THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS A VOTE "FOR" THE
RATIFICATION OF THE APPOINTMENT OF ARTHUR ANDERSEN LLP AS INDEPENDENT AUDITORS.
 
            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
    Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
executive officers and directors and persons who own more than ten percent of a
registered class of the Company's equity securities to file an initial report of
ownership on Form 3 and changes in ownership on Form 4 or 5 with the SEC.
Executive officers, directors and greater than ten percent stockholders are also
required by SEC rules to furnish the Company with copies of all Section 16(a)
forms they file. Based solely on its review of the copies of such forms received
by it, or written representations form certain reporting persons, the Company
believes that during the last fiscal year, all Section 16(a) filing requirements
applicable to its officers, directors and ten percent stockholders were complied
with.
 
                           PROPOSALS OF STOCKHOLDERS
 
    Proposals that stockholders desire to have included in the Company's proxy
materials for the 1999 Annual Meeting of Stockholders of the Company must be
received by the Secretary of the Company at its principal office (1625 Sharp
Point Drive, Fort Collins, Colorado 80525) no later than December 3, 1998 in
order to be considered for inclusion in such proxy materials.
 
                                   FORM 10-K
 
    A copy of the Company's 1997 Annual Report on Form 10-K will be available
without charge upon request to: Investor Relations, Advanced Energy Industries,
Inc. 1625 Sharp Point Drive, Fort Collins, Colorado 80525.
 
                                 OTHER MATTERS

3.   ADMINISTRATION.

     (a)  The Plan shall be administered by the Board unless and until the 
Board delegates administration to a Committee, as provided in subsection 3(c).

     (b)  The Board shall have the power, subject to, and within the 
limitations of, the express provisions of the Plan:

          (1)  To determine from time to time which of the persons eligible 
under the Plan shall be granted Options; when and how each Option shall be 
granted; whether an Option will be an Incentive Stock Option or a 
Nonstatutory Stock Option; the provisions of each Option granted (which need 
not be identical), including the time or times such Option may be exercised 
in whole or in part; and the number of shares for which an Option shall be 
granted to each such person.

          (2)  To construe and interpret the Plan and Options granted under 
it, and to establish, amend and revoke rules and regulations for its 
administration. The Board, in the exercise of this power, may correct any 
defect, omission or inconsistency in the Plan or in any Option Agreement, in 
a manner and to the extent it shall deem necessary or expedient to make the 
Plan fully effective.

          (3)  To amend the Plan as provided in Section 11.

     (c)  The Board may delegate administration of the Plan to a committee 
composed of not fewer than two (2) members (the "Committee"), all of the 
members of which Committee shall be Disinterested Persons and may also be, in 
the discretion of the Board, Outside Directors. If administration is 
delegated to a Committee, the Committee shall have, in connection with the 
administration of the Plan, the powers theretofore possessed by the Board 
(and references in this Plan to the Board shall thereafter be to the 
Committee), subject, however, to such resolutions, not inconsistent with the 
provisions of the Plan, as may be adopted from time to time by the Board. The 
Board may abolish the Committee at any time and revest in the Board the 
administration of the Plan. Additionally, prior to the date of the first 
registration of an equity security of the Company under Section 12 of the 
Exchange Act, and notwithstanding anything to the contrary contained

                                       4
<PAGE>


herein, the Board may delegate administration of the Plan to any person or 
persons and the term "Committee" shall apply to any person or persons to whom 
such authority has been delegated. Notwithstanding anything in this Section 3 
to the contrary, the Board or the Committee may delegate to a committee of 
one or more members of the Board the authority to grant Options to eligible 
persons who (1) are not then subject to Section 16 of the Exchange Act and/or 
(2) are either (i) not then Covered Employees and are not expected to be 
Covered Employees at the time of recognition of income resulting from such 
Option, or (ii) not persons with respect to whom the Company wishes to comply 
with Section 162(m) of the Code.

     (d)  Any requirement that an administrator of the Plan be a 
Disinterested Person shall not apply (i) prior to the date of the first 
registration of an equity security of the Company under Section 12 of the 
Exchange Act, or (ii) if the Board or the Committee expressly declares that 
such requirement shall not apply. Any Disinterested Person shall otherwise 
comply with the requirements of Rule 16b-3.

4.  SHARES SUBJECT TO THE PLAN.

     (a)  Subject to the provisions of Section 10 relating to adjustments 
upon changes in stock, the stock that may be sold pursuant to Options shall 
not exceed in the aggregate four million six hundred twenty-five thousand 
(4,625,000) shares of the Company's common stock. If any Option shall for any 
reason expire or otherwise terminate, in whole or in part, without having 
been exercised in full, the stock not purchased under such Option shall 
revert to and again become available for issuance under the Plan.

     (b)  The stock subject to the Plan may be unissued shares or reacquired 
shares, bought on the market or otherwise.

5.  ELIGIBILITY.

     (a)  Incentive Stock Options may be granted only to Employees. 
Nonstatutory Stock Options may be granted only to Employees, Directors or 
Consultants.

                                       5
<PAGE>


     (b)  A Director shall in no event be eligible for the benefits of the 
Plan unless at the time discretion is exercised in the selection of the 
Director as a person to whom Options may be granted, or in the determination 
of the number of shares which may be covered by Options granted to the 
Director: (i) the Board has delegated its discretionary authority over the 
Plan to a Committee which consists solely of Disinterested Persons; or (ii) 
the Plan otherwise complies with the requirements of Rule 16b-3. The Board 
shall otherwise comply with the requirements of Rule 16b-3. This subsection 
5(b) shall not apply (i) prior to the date of the first registration of an 
equity security of the Company under Section 12 of the Exchange Act, or (ii) 
if the Board or Committee expressly declares that it shall not apply.

     (c)  No person shall be eligible for the grant of an Option if, at the 
time of grant, such person owns (or is deemed to own pursuant to Section 
424(d) of the Code) stock possessing more than ten percent (10%) of the total 
combined voting power of all classes of stock of the Company or of any of its 
Affiliates unless the exercise price of such Option is at least one hundred 
ten percent (110%) of the Fair Market Value of such stock at the date of 
grant and the Option is not exercisable after the expiration of five (5) 
years from the date of grant.

     (d)  Subject to the provisions of Section 10 relating to adjustments 
upon changes in stock, no person shall be eligible to be granted Options 
covering more than three hundred thousand (300,000) shares of the Company's 
common stock in any calendar year.

6.   OPTION PROVISIONS.

     Each Option shall be in such form and shall contain such terms and 
conditions as the Board shall deem appropriate. The provisions of separate 
Options need not be identical, but each Option shall include (through 
incorporation of provisions hereof by reference in the Option or otherwise) 
the substance of each of the following provisions:

     (a)  TERM.  No Option shall be exercisable after the expiration of ten 
(10) years from the date it was granted.

                                       6
<PAGE>


     (b)  PRICE.  The exercise price of each Incentive Stock Option shall be 
not less than one hundred percent (100%) of the Fair Market Value of the 
stock subject to the Option on the date the Option is granted. The exercise 
price of each Nonstatutory Stock Option shall be not less than eighty-five 
percent (85%) of the Fair Market Value of the stock subject to the Option on 
the date the Option is granted.

     (c)  CONSIDERATION.  The purchase price of stock acquired pursuant to an 
Option shall be paid, to the extent permitted by applicable statutes and 
regulations, either (i) in cash at the time the Option is exercised, or (ii) 
at the discretion of the Board or the Committee, either at the time of the 
grant or exercise of the Option, (A) by delivery to the Company of other 
common stock of the Company, (B) according to a deferred payment or other 
arrangement (which may include, without limiting the generality of the 
foregoing, the use of other common stock of the Company) with the person to 
whom the Option is granted or to whom the Option is transferred pursuant to 
subsection 6(d), or (C) in any other form of legal consideration that may be 
acceptable to the Board.

      In the case of any deferred payment arrangement, interest shall be 
payable at least annually and shall be charged at the minimum rate of 
interest necessary to avoid the treatment as interest, under any applicable 
provisions of the Code, of any amounts other than amounts stated to be 
interest under the deferred payment arrangement.

     (d)  TRANSFERABILITY.  An Incentive Stock Option shall not be 
transferable except by will or by the laws of descent and distribution, and 
shall be exercisable during the lifetime of the person to whom the Incentive 
Stock Option is granted only by such person. A Nonstatutory Stock Option 
shall not be transferable except by will or by the laws of descent and 
distribution or pursuant to a qualified domestic relations order satisfying 
the requirements of Rule 16b-3 and the rules thereunder (a "QDRO"), and shall 
be exercisable during the lifetime of the person to whom the Option is 
granted only by such person or any transferee pursuant to a QDRO. The person 
to whom the Option is granted may, by delivering written notice to the 
Company, in a form satisfactory to

                                       7
<PAGE>


the Company, designate a third party who, in the event of the death of the 
Optionee, shall thereafter be entitled to exercise the Option.

     (e)  VESTING.  The total number of shares of stock subject to an Option 
may, but need not, be allotted in periodic installments (which may, but need 
not, be equal). The Option Agreement may provide that from time to time 
during each of such installment periods, the Option may become exercisable 
("vest") with respect to some or all of the shares allotted to that period, 
and may be exercised with respect to some or all of the shares allotted to 
such period and/or any prior period as to which the Option became vested but 
was not fully exercised. The Option may be subject to such other terms and 
conditions on the time or times when it may be exercised (which may be based 
on performance or other criteria) as the Board may deem appropriate. The 
vesting provisions of individual Options may vary but in each case will 
provide for vesting of at least twenty percent (20%) per year of the total 
number of shares subject to the Option. The provisions of this subsection 
6(e) are subject to any Option provisions governing the minimum number of 
shares as to which an Option may be exercised.

     (f)  SECURITIES LAW COMPLIANCE. The Company may require any Optionee, or 
any person to whom an Option is transferred under subsection 6(d), as a 
condition of exercising any such Option, (1) to give written assurances 
satisfactory to the Company as to the Optionee's knowledge and experience in 
financial and business matters and/or to employ a purchaser representative 
reasonably satisfactory to the Company who is knowledgeable and experienced 
in financial and business matters, and that he or she is capable of 
evaluating, alone or together with the purchaser representative, the merits 
and risks of exercising the Option; and (2) to give written assurances 
satisfactory to the Company stating that such person is acquiring the stock 
subject to the Option for such person's own account and not with any present 
intention of selling or otherwise distributing the stock. The foregoing 
requirements, and any assurances given pursuant to such requirements, shall 
be inoperative if (i) the issuance of the shares upon the exercise of the 
Option has been registered under a then currently effective registration 
statement under the Securities Act

                                       8
<PAGE>


of 1933, as amended (the "Securities Act"), or (ii) as to any particular 
requirement, a determination is made by counsel for the Company that such 
requirement need not be met in the circumstances under the then applicable 
securities laws. The Company may, upon advice of counsel to the Company, 
place legends on stock certificates issued under the Plan as such counsel 
deems necessary or appropriate in order to comply with applicable securities 
laws, including, but not limited to, legends restricting the transfer of the 
stock.

      (g)  TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR 
CONSULTANT. In the event an Optionee's Continuous Status as an Employee, 
Director or Consultant terminates (other than upon the Optionee's death or 
disability), the Optionee may exercise his or her Option (to the extent that 
the Optionee was entitled to exercise it at the date of termination) but only 
within such period of time ending on the earlier of (i) the date three (3) 
months after the termination of the Optionee's Continuous Status as an 
Employee, Director or Consultant (or such longer or shorter period, which in 
no event shall be less than thirty (30) days, specified in the Option 
Agreement), or (ii) the expiration of the term of the Option as set forth in 
the Option Agreement. If, after termination, the Optionee does not exercise 
his or her Option within the time specified in the Option Agreement, the 
Option shall terminate, and the shares covered by such Option shall revert to 
and again become available for issuance under the Plan.

     (h)  DISABILITY OF OPTIONEE. In the event an Optionee's Continuous 
Status as an Employee, Director or Consultant terminates as a result of the 
Optionee's disability, the Optionee may exercise his or her Option (to the 
extent that the Optionee was entitled to exercise it at the date of 
termination), but only within such period of time ending on the earlier of 
(i) the date twelve (12) months following such termination (or such longer or 
shorter period, which in no event shall be less than six (6) months, 
specified in the Option Agreement), or (ii) the expiration of the term of the 
Option as set forth in the Option Agreement. If, at the date of termination, 
the Optionee is not entitled to exercise his or her entire Option, the shares 
covered by the unexercisable portion of the Option shall revert to and again 
become available for issuance under the Plan. If, after termination,

                                       9
<PAGE>


the Optionee does not exercise his or her Option within the time specified 
herein, the Option shall terminate, and the shares covered by such Option 
shall revert to and again become available for issuance under the Plan.

     (i)  DEATH OF OPTIONEE.  In the event of the death of an Optionee 
during, or within a period specified in the Option after the termination of, 
the Optionee's Continuous Status as an Employee, Director or Consultant, the 
Option may be exercised (to the extent the Optionee was entitled to exercise 
the Option at the date of death) by the Optionee's estate, by a person who 
acquired the right to exercise the Option by bequest or inheritance or by a 
person designated to exercise the option upon the Optionee's death pursuant 
to subsection 6(d), but only within the period ending on the earlier of (i) 
the date eighteen (18) months following the date of death (or such longer or 
shorter period, which in no event shall be less than six (6) months, 
specified in the Option Agreement), or (ii) the expiration of the term of 
such Option as set forth in the Option Agreement. If, at the time of death, 
the Optionee was not entitled to exercise his or her entire Option, the 
shares covered by the unexercisable portion of the Option shall revert to and 
again become available for issuance under the Plan. If, after death, the 
Option is not exercised within the time specified herein, the Option shall 
terminate, and the shares covered by such Option shall revert to and again 
become available for issuance under the Plan.

     (j)  EARLY EXERCISE.  The Option may, but need not, include a provision 
whereby the Optionee may elect at any time while an Employee, Director or 
Consultant to exercise the Option as to any part or all of the shares subject 
to the Option prior to the full vesting of the Option. Any unvested shares so 
purchased shall be subject to a repurchase right in favor of the Company, 
with the repurchase price to be equal to the original purchase price of the 
stock, or to any other restriction the Board determines to be appropriate; 
provided, however, that (i) the right to repurchase at the original purchase 
price shall lapse at a minimum rate of twenty percent (20%) per year over 
five (5) years from the date the Option was granted, and (ii) such right 
shall be exercisable only within (A) the ninety (90) day period following the 
termination of employment [or

                                      10
<PAGE>


the relationship as a Director or Consultant, or (B) such longer period as 
may be agreed to by the Company and the Optionee (for example, for purposes 
of satisfying the requirements of Section 1202(c)(3) of the Code (regarding 
"qualified small business stock")), and (iii) such right shall be exercisable 
only for cash or cancellation of purchase money indebtedness for the shares. 
Should the right of repurchase be assigned by the Company, the assignee shall 
pay the Company cash equal to the difference between the original purchase 
price and the stock's Fair Market Value if the original purchase price is 
less than the stock's Fair Market Value.

     (k)  WITHHOLDING. To the extent provided by the terms of an Option 
Agreement, the Optionee may satisfy any federal, state or local tax 
withholding obligation relating to the exercise of such Option by any of the 
following means or by a combination of such means: (1) tendering a cash 
payment; (2) authorizing the Company to withhold shares from the shares of 
the common stock otherwise issuable to the participant as a result of the 
exercise of the Option; or (3) delivering to the Company owned and 
unencumbered shares of the common stock of the Company.

7.  COVENANTS OF THE COMPANY.

     (a)  During the terms of the Options, the Company shall keep available 
at all times the number of shares of stock required to satisfy such Options.

     (b)  The Company shall seek to obtain from each regulatory commission or 
agency having jurisdiction over the Plan such authority as may be required to 
issue and sell shares of stock upon exercise of the Options; provided, 
however, that this undertaking shall not require the Company to register 
under the Securities Act either the Plan, any Option or any stock issued or 
issuable pursuant to any such Option. If, after reasonable efforts, the 
Company is unable to obtain from any such regulatory commission or agency the 
authority which counsel for the Company deems necessary for the lawful 
issuance and sale of stock under the Plan, the Company shall be relieved from 
any liability for failure to issue and sell stock upon exercise of such 
Options unless and until such authority is obtained.

8.  USE OF PROCEEDS FROM STOCK.

                                       11
<PAGE>


     Proceeds from the sale of stock pursuant to Options shall constitute 
general funds of the Company.

9.   MISCELLANEOUS.

     (a)  Neither an Optionee nor any person to whom an Option is transferred 
under subsection 6(d) shall be deemed to be the holder of, or to have any of 
the rights of a holder with respect to, any shares subject to such Option 
unless and until such person has satisfied all requirements for exercise of 
the Option pursuant to its terms.

     (b)  Throughout the term of any Option, the Company shall deliver to the 
holder of such Option, not later than one hundred twenty (120) days after the 
close of each of the Company's fiscal years during the Option term, a balance 
sheet and an income statement. This section shall not apply when issuance is 
limited to key employees whose duties in connection with the Company assure 
them access to equivalent information.

     (c)  Nothing in the Plan or any instrument executed or Option granted 
pursuant thereto shall confer upon any Employee, Director, Consultant or 
Optionee any right to continue in the employ of the Company or any Affiliate 
or to continue acting as a Director or Consultant or shall affect the right 
of the Company or any Affiliate to terminate the employment or relationship 
as a Director or Consultant of any Employee, Director, Consultant or Optionee 
with or without cause.

     (d)  To the extent that the aggregate Fair Market Value (determined at 
the time of grant) of stock with respect to which Incentive Stock Options 
granted after 1986 are exercisable for the first time by any Optionee during 
any calendar year under all plans of the Company and its Affiliates exceeds 
one hundred thousand dollars ($100,000), the Options or portions thereof 
which exceed such limit (according to the order in which they were granted) 
shall be treated as Nonstatutory Stock Options.

     (e)  (1)  The Board or the Committee shall have the authority to effect, 
at any time and from time to time (i) the repricing of any outstanding 
Options under the Plan and/or (ii) with the consent of the affected holders 
of Options, the cancellation of any outstanding Options and the

                                      12
<PAGE>


grant in substitution therefor of new Options under the Plan covering the 
same or different numbers of shares of Common Stock, but having an exercise 
price per share not less than eighty-five percent (85%) of the Fair Market 
Value (one hundred percent (100%) of the Fair Market Value in the case of an 
Incentive Stock Option or, in the case of a ten percent (10%) stockholder (as 
defined in subsection 5(c)), not less than one hundred and ten percent (110%) 
of the Fair Market Value) per share of Common Stock on the new grant date.

     (2)  Shares subject to an Option canceled under this subsection 9(e) 
shall continue to be counted against the maximum award of Options permitted 
to be granted pursuant to subsection 5(d) of the Plan. The repricing of an 
Option under this subsection 9(e), resulting in a reduction of the exercise 
price, shall be deemed to be a cancellation of the original Option and the 
grant of a substitute Option; in the event of such repricing, both the 
original and the substituted Options shall be counted against the maximum 
awards of Options permitted to be granted pursuant to subsection 5(d) of the 
Plan. The provisions of this subsection 9(e) shall be applicable only to the 
extent required by Section 162(m) of the Code.

10. ADJUSTMENTS UPON CHANGES IN STOCK.

     (a)  If any change is made in the stock subject to the Plan, or subject 
to any Option (through merger, consolidation, reorganization, 
recapitalization, stock dividend, dividend in property other than cash, stock 
split, liquidating dividend, combination of shares, exchange of shares, 
change in corporate structure or otherwise), the Plan will be appropriately 
adjusted in the class(es) and maximum number of shares subject to the Plan 
pursuant to subsection 4(a) and the maximum number of shares subject to award 
to any person during any calendar year pursuant to subsection 5(d), and the 
outstanding Options will be appropriately adjusted in the class(es) and 
number of shares and price per share of stock subject to such outstanding 
Options.

   (b)  In the event of: (1) a merger or consolidation in which the Company 
is not the surviving corporation or (2) a reverse merger in which the Company 
is the surviving corporation but the shares of the Company's common stock 
outstanding immediately preceding the merger are

                                      13
<PAGE>


converted by virtue of the merger into other property, whether in the form of 
securities, cash or otherwise then to the extent permitted by applicable law: 
(i) any surviving corporation shall assume any Options outstanding under the 
Plan or shall substitute similar Options for those outstanding under the 
Plan, or (ii) such Options shall continue in full force and effect. In the 
event any surviving corporation refuses to assume or continue such Options, 
or to substitute similar options for those outstanding under the Plan, then 
such Options shall be terminated if not exercised prior to such event. In the 
event of a dissolution or liquidation of the Company, any Options outstanding 
under the Plan shall terminate if not exercised prior to such event.

11. AMENDMENT OF THE PLAN.

     (a)   The Board at any time, and from time to time, may amend the Plan. 
However, except as provided in Section 10 relating to adjustments upon 
changes in stock, no amendment shall be effective unless approved by the 
stockholders of the Company within twelve (12) months before or after the 
adoption of the amendment, where the amendment will:

          (1)  Increase the number of shares reserved for Options under the 
Plan;

          (2)  Modify the requirements as to eligibility for participation in 
the Plan (to the extent such modification requires stockholder approval in 
order for the Plan to satisfy the requirements of Section 422 of the Code); or

          (3)  Modify the Plan in any other way if such modification requires 
stockholder approval in order for the Plan to satisfy the requirements of 
Section 422 of the Code or to comply with the requirements of Rule 16b-3.

     (b)  The Board may in its sole discretion submit any other amendment to 
the Plan for stockholder approval, including, but not limited to, amendments 
to the Plan intended to satisfy the requirements of Section 162(m) of the 
Code and the regulations promulgated thereunder regarding the exclusion of
