                                 FIBERCHEM, INC.

                         1999 EMPLOYEE STOCK OPTION PLAN

1.   Purposes.

     The FIBERCHEM, INC. 1999 EMPLOYEE STOCK OPTION PLAN (the "Plan") is
intended to provide the employees, directors, independent contractors and
consultants of FiberChem, Inc. (the "Company") and/or any subsidiary or parent
thereof with an added incentive to commence and/or continue their services to
the Company and to induce them to exert their maximum efforts toward the
Company's success. By thus encouraging employees, directors, independent
contractors and consultants and promoting their continued association with the
Company, the Plan may be expected to benefit the Company and its stockholders.
The Plan allows the Company to grant Incentive Stock Options ("ISOs") (as
defined in Section 422(b) of the Internal Revenue Code of 1986, as amended (the
"Code"), Non-Qualified Stock Options ("NQSOs") not intended to qualify under
Section 422(b) of the Code and Stock Appreciation Rights ("SARs") (collectively
the "Options"). The vesting of one or more Options granted hereunder may be
based on the attainment of specified performance goals of the participant or the
performance of the Company, one or more subsidiaries, parent and/or division of
one or more of the above.

2.   Shares Subject to the Plan.

     The total number of shares of Common Stock of the Company, $.0001 par value
per share, that may be subject to Options granted under the Plan shall be five
million (5,000,000) in the aggregate, subject to adjustment as provided in
Paragraph 8 of the Plan; however, the grant of an ISO to an employee together
with a tandem SAR or any NQSO to an employee together with a tandem SAR shall
only require one share of Common Stock available subject to the Plan to satisfy
such joint Option. The Company shall at all times while the Plan is in force
reserve such number of shares of Common Stock as will be sufficient to satisfy
the requirement of outstanding Options granted under the Plan. In the event any
Option granted under the Plan shall expire or terminate for any reason without
having been exercised in full or shall cease for any reason to be exercisable in
whole or in part, the unpurchased shares subject thereto shall again be
available for granting of Options under the Plan.

3.   Eligibility.

     ISO's or ISO's in tandem with SAR's (provided the SAR meets the
requirements set forth in Temp. Reg. Section 14a.422A-1, A-39 (a) through (e)
inclusive) may be granted from time to time under the Plan to one or more
employees of the Company or of a "subsidiary" or "parent" of the Company, as the
quoted terms are defined within Section 424 of the Code. An Officer is an
employee for the above purposes. However, a director of the Company who is not
otherwise an employee is not deemed an employee for such purposes. NQSOs and
SARs may be granted from time to time under the Plan to one or more employees of
the Company, Officers, members of the Board of Directors, independent
contractors, consultants and other individuals who are not employees of, but are
involved in the continuing development and success of the Company and/or of a
subsidiary of the Company, including persons who have previously been granted
Options under the Plan.

     4.   Administration of the Plan.

          (a)  The Plan shall be administered by the Board of Directors of the
Company as such Board of Directors may be composed from time to time and/or by a
Stock Option Committee or Compensation Committee (the "Committee") which shall
be comprised of solely of at least two Outside Directors (as such term is
defined in regulations promulgated from time to time with respect to Section
162(m)(4)(C)(i) of the Code) appointed by such Board of Directors of the
Company. As and to the extent authorized by the Board of Directors of the
Company, the Committee may exercise the power and authority vested in the Board
of Directors under the Plan. Within the limits of the express provisions of the
Plan, the Board of Directors or Committee shall have the authority, in its
discretion, to determine the individuals to whom, and the time or times at
which, Options shall be granted, the character of such Options (whether ISOs,
NQSOs, and/or SARs in tandem with NQSOs, and/or SARs in tandem with ISOs) and
the number of shares of Common Stock to be subject to each Option, the manner
and form in which the optionee can tender payment upon the exercise of his
Option, and to interpret the Plan, to prescribe, amend and rescind rules and
regulations relating to the Plan, to determine the terms and provisions of
Option agreements that may be entered into in connection with Options (which
need not be identical), subject to the limitation that agreements granting ISOs
must be consistent with the requirements for the ISOs being qualified as
"incentive stock options" as provided in Section 422 of the Code, and to make
all other determinations and take all other actions necessary or advisable


                                       2
<PAGE>


for the administration of the Plan. In making such determinations, the Board of
Directors and/or the Committee may take into account the nature of the services
rendered by such individuals, their present and potential contributions to the
Company's success, and such other factors as the Board of Directors and/or the
Committee, in its discretion, shall deem relevant. The Board of Directors'
and/or the Committee's determinations on the matters referred to in this
Paragraph shall be conclusive.

          (b)  Notwithstanding anything contained herein to the contrary, at
anytime during the period the Company's Common Stock is registered pursuant to
Section 12(g) of the Securities Exchange Act of 1934 (the "1934 Act), the
Committee, if one has been appointed to administer all or part of the Plan,
shall have the exclusive right to grant Options to Covered Employees as defined
under Section 162(m)(3) of the Code (generally executive officers subject to
Section 16 of the 1934 Act) and set forth the terms and conditions thereof. With
respect to persons subject to Section 16 of the 1934 Act, transactions under the
Plan are intended, to the extent possible, to comply with all applicable
conditions of Rule 16b-3, as amended from time to time, (and its successor
provisions, if any) under the 1934 Act and Section 162(m)(4)(C) of the Code of
1986, as amended. To the extent any provision of the Plan or action by the Board
of Directors or Committee fails to so comply, it shall be deemed null and void,
to the extent permitted by law and deemed advisable by the Board of Directors
and/or such Committee.

5.   Terms of Options.

     Within the limits of the express provisions of the Plan, the Board of
Directors or the Committee may grant either ISOs or NQSOs or SARs in tandem with
NQSOs or SARs in tandem with ISOs. An ISO or an NQSO enables the optionee to
purchase from the Company, at any time during a specified exercise period, a
specified number of shares of Common Stock at a specified price (the "Option
Price"). The optionee, if granted a SAR in tandem with a NQSO or ISO, may
receive from the Company, in lieu of exercising his option to purchase shares
pursuant to his NQSO or ISO, at one of the certain specified times during the
exercise period of the NQSO or ISO as set by the Board of Directors or the
Committee, the excess of the fair market value upon such exercise (as determined
in accordance with subparagraph (b) of this Paragraph 5) of one share of Common
Stock over the Option Price per share specified upon grant of the NQSO or
ISO/SAR multiplied by the number of shares of Common Stock covered by the SAR so
exercised. The character and terms of each Option granted under


                                       3
<PAGE>


the Plan shall be determined by the Board of Directors and/or the Committee
consistent with the provisions of the Plan, including the following:

     (a)  An Option granted under the Plan must be granted within 10 years from
the date the Plan is adopted, or the date the Plan is approved by the
stockholders of the Company, whichever is earlier.

     (b)  The Option Price of the shares of Common Stock subject to each ISO and
each SAR issued in tandem with an ISO shall not be less than the fair market
value of such shares of Common Stock at the time such ISO is granted. Such fair
market value shall be determined by the Board of Directors and, if the shares of
Common Stock are listed on a national securities exchange or traded on the
over-the-counter market, the fair market value shall be the closing price on
such exchange, or the mean of the closing bid and asked prices of the shares of
Common Stock on the over-the-counter market, as reported by the Nasdaq Stock
Market, the National Association of Securities Dealers OTC Bulletin Board or the
National Quotation Bureau, Inc., as the case may be, on the day on which the
Option is granted or, if there is no closing price or bid or asked price on that
day, the closing price or mean of the closing bid and asked prices on the most
recent day preceding the day on which the Option is granted for which such
prices are available. If an ISO or SAR in tandem with an ISO is granted to any
individual who, immediately before the ISO is to be granted, owns (directly or
through attribution) more than 10% of the total combined voting power of all
classes of capital stock of the Company or a subsidiary or parent of the
Company, the Option Price of the shares of Common Stock subject to such ISO
shall not be less than 110% of the fair market value per share of the shares of
Common Stock at the time such ISO is granted.

     (c)  The Option Price of the shares of Common Stock subject to an NQSO or
an SAR in tandem with a NQSO granted pursuant to the Plan shall be determined by
the Board of Directors or the Committee, in its sole discretion, but in no event
less than 85% of the fair market value per share of the shares of Common Stock
at the time of grant.

     (d)  In no event shall any Option granted under the Plan have an expiration
date later than 10 years from the date of its grant, and all Options granted
under the Plan shall be subject to earlier termination as expressly provided in
Paragraph 6 hereof. If an ISO or an SAR in tandem with an ISO is granted to any
individual who, immediately before the ISO is granted, owns


                                       4
<PAGE>


(directly or through attribution) more that 10% of the total combined voting
power of all classes of capital stock of the Company or of a subsidiary or
parent of the Company, such ISO shall by its terms expire and shall not be
exercisable after the expiration of five (5) years from the date of its grant.

     (e)  An SAR may be exercised at any time during the exercise period of the
ISO or NQSO with which it is granted in tandem and prior to the exercise of such
ISO or NQSO. Notwithstanding the foregoing, the Board of Directors and/or the
Committee shall in their discretion determine from time to time the terms and
conditions of SAR's to be granted, which terms may vary from the afore-described
conditions, and which terms shall be set forth in a written stock option
agreement evidencing the SAR granted in tandem with the ISO or NQSO. The
exercise of an SAR granted in tandem with an ISO or NQSO shall be deemed to
cancel such number of shares subject to the unexercised Option as were subject
to the exercised SAR. The Board of Directors or the Committee has the discretion
to alter the terms of the SARS if necessary to comply with Federal or state
securities law. Amounts to be paid by the Company in connection with an SAR may,
in the Board of Director's or the Committee's discretion, be made in cash,
Common Stock or a combination thereof.

     (f)  An Option granted under the Plan shall become exercisable, in whole at
any time or in part from time to time, but in no event may an Option (i) be
exercised as to less than one hundred (100) shares of Common Stock at any one
time, or the remaining shares of Common Stock covered by the Option if less than
one hundred (100), and (ii) except with respect to performance based Options,
become fully exercisable more than five years from the date of its grant nor
shall less than 20% of the Option become exercisable in any of the first five
years of the Option, if not terminated as provided in Section 6 hereof. The
Board of Directors or the Committee, if applicable, shall, in the event it so
elects in its sole discretion, set one or more performance standards with
respect to one or more Options upon which vesting is conditioned (which
performance standards may vary among the Options).

     (g)  An Option granted under the Plan shall be exercised by the delivery by
the holder thereof to the Company at its principal office (to the attention of
the Secretary) of written notice of the number of full shares of Common Stock
with respect to which the Option is being exercised, accompanied by payment in
full, which payment at the option of the optionee shall be in the form of (i)
cash or certified or bank check payable to the order of the Company, of the
Option Price of such shares of Common


                                       5
<PAGE>


Stock, or, (ii) if permitted by the Committee or the Board of Directors, as
determined by the Committee or the Board of Directors in its sole discretion at
the time of the grant of the Option with respect to an ISO and at or prior to
the time of exercise with respect to a NQSO, by the delivery of shares of Common
Stock having a fair market value equal to the Option Price or the delivery of an
interest-bearing promissory note having an original principal balance equal to
the Option Price and an interest rate not below the rate which would result in
imputed interest under the Code (provided, in order to qualify as an ISO, more
than one year shall have passed since the date of grant and one year from the
date of exercise), or (iii) at the option of the Committee or the Board of
Directors, determined by the Committee or the Board of Directors in its sole
discretion at the time of the grant of the Option with respect to an ISO and at
or prior to the time of exercise with respect to a NQSO, by a combination of
cash, promissory note and/or such shares of Common Stock (subject to the
restriction above) held by the employee that have a fair market value together
with such cash and principal amount of any promissory note that shall equal the
Option Price, and, in the case of a NQSO, at the discretion of the Committee or
Board of Directors by having the Company withhold from the shares of Common
Stock to be issued upon exercise of the Option that number of shares having a
fair market value equal to the exercise price and/or the tax withholding amount
due, or otherwise provide for withholding as set forth in Paragraph 9(c) hereof,
or in the event an employee is granted an ISO or NQSO in tandem with an SAR and
desires to exercise such SAR, such written notice shall so state such intention.
To the extent allowed by applicable Federal and state securities laws, the
Option Price may also be paid in full by a broker-dealer to whom the optionee
has submitted an exercise notice consisting of a fully endorsed Option, or
through any other medium of payment as the Board of Directors and/or the
Committee, in its discretion, shall authorize.

     (h)  The holder of an Option shall have none of the rights of a stockholder
with respect to the shares of Common Stock covered by such holder's Option until
such shares of Common Stock shall be issued to such holder upon the exercise of
the Option.

     (i)  All ISOs or SARs in tandem with ISOs granted under the Plan shall not
be transferable otherwise than by will or the laws of descent and distribution
and may be exercised during the lifetime of the holder thereof only by the
holder. The Board or the Committee, in its sole discretion, shall determine
whether an Option other than an ISO or SAR in tandem


                                       6
<PAGE>


with an ISO shall be transferable. No Option granted under the Plan shall be
subject to execution, attachment or other process.

     (j)  The aggregate fair market value, determined as of the time any ISO or
SAR in tandem with an ISO is granted and in the manner provided for by
Subparagraph (b) of this Paragraph 5, of the shares of Common Stock with respect
to which ISOs granted under the Plan are exercisable for the first time during
any calendar year and under incentive stock options qualifying as such in
accordance with Section 422 of the Code granted under any other incentive stock
option plan maintained by the Company or its parent or subsidiary corporations,
shall not exceed $100,000. Any grant of Options in excess of such amount shall
be deemed a grant of a NQSO.

     (k)  Notwithstanding anything contained herein to the contrary, an SAR
which was granted in tandem with an ISO shall (i) expire no later than the
expiration of the underlying ISO; (ii) be for no more than 100% of the spread at
the time the SAR is exercised; (iii) shall only be transferable when the
underlying ISO is transferable; (iv) only be exercised when the underlying ISO
is eligible to be exercised; and (v) only be exercisable when there is a
positive spread.

6.   Death or Termination of Employment/Consulting Relationship.

     (a)  Except as provided herein, or otherwise determined by the Board of
Directors or the Committee in its sole discretion, upon termination of
employment with the Company voluntarily by the employee or termination of a
consulting relationship with the Company prior to the termination of the term
thereof, a holder of an Option under the Plan may exercise such Options to the
extent such Options were exercisable as of the date of termination at any time
within thirty (30) days after termination, subject to the provisions of
Subparagraph (d) of this Paragraph 6. Except as provided herein, or otherwise
determined by the Board of Directors or the Committee in its sole discretion, if
such employment or consulting relationship shall terminate for any reason other
than death, voluntary termination by the employee or for cause, then such
Options may be exercised at anytime within three (3) months after such
termination. Notwithstanding anything contained herein to the contrary, unless
otherwise determined by the Board of Directors or the Committee in its sole
discretion, any options granted hereunder to an Optionee and then outstanding
shall immediately terminate in the event the Optionee is terminated for cause,
and the other


                                       7
<PAGE>


provisions of this Section 6 shall not be applicable thereto. For
purposes of this Section 6, termination for cause shall be deemed the decision
of the Company, in its sole discretion, that Optionee has not adequately
performed the services for which he/she/it was hired.

     (b)  If the holder of an Option granted under the Plan dies (i) while
employed by the Company or a subsidiary or parent corporation or while providing
consulting services to the Company or a subsidiary or parent corporation or (ii)
within three (3) months after the termination of such holder's
employment/consulting, such Options may, subject to the provisions of
subparagraph (d) of this Paragraph 6, be exercised by a legatee or legatees of
such Option under such individual's last will or by such individual's personal
representatives or distributees at any time within such time as determined by
the Board of Directors or the Committee in its sole discretion, but in no event
less than six months after the individual's death, to the extent such Options
were exercisable as of the date of death or date of termination of employment,
whichever date is earlier.

     (c)  If the holder of an Option under the Plan becomes disabled within the
definition of section 22(e)(3) of the Code while employed by the Company or a
subsidiary or parent corporation, such Option may, subject to the provisions of
subparagraph (d) of this Paragraph 6, be exercised at any time within six months
less one day after such holder's termination of employment due to the
disability.

     (d)  Except as otherwise determined by the Board of Directors or the
Committee in its sole discretion, an Option may not be exercised pursuant to
this Paragraph 6 except to the extent that the holder was entitled to exercise
the Option at the time of termination of employment, consulting relationship or
death, and in any event may not be exercised after the original expiration date
of the Option. Notwithstanding anything contained herein which may be to the
contrary, such termination or death prior to vesting shall, unless otherwise
determined by the Board of Directors or Committee, in its sole discretion, be
deemed to occur at a time the holder was not entitled to exercise the Option.

     (e)  The Board of Directors or the Committee, in its sole discretion, may
at such time or times as it deems appropriate, if ever, accelerate all or part
of the vesting provisions with respect to one or more outstanding options. The
acceleration of one Option shall not infer that any Option is or to be
accelerated.

<PAGE>


7.   Leave of Absence.

     For the purposes of the Plan, an individual who is on military or sick
leave or other bona fide leave of absence (such as temporary employment by the
Government) shall be considered as remaining in the employ of the Company or of
a subsidiary or parent corporation for ninety (90) days or such longer period as
such individual's right to reemployment is guaranteed either by statute or by
contract.

8.   Adjustment Upon Changes in Capitalization.

     (a)  In the event that the outstanding shares of Common Stock are hereafter
changed by reason of recapitalization, reclassification, stock split-up,
combination or exchange of shares of Common Stock or the like, or by the
issuance of dividends payable in shares of Common Stock, an appropriate
adjustment shall be made by the Board of Directors, as determined by the Board
of Directors and/or the Committee, in the aggregate number of shares of Common
Stock available under the Plan, in the number of shares of Common Stock issuable
upon exercise of outstanding Options, and the Option Price per share. In the
event of any consolidation or merger of the Company with or into another
company, where the Company is not the surviving entity, or the conveyance of all
or substantially all of the assets of the Company to another company for solely
stock and/or securities, each then outstanding Option shall upon exercise
thereafter entitle the holder thereof to such number of shares of Common Stock
or other securities or property to which a holder of shares of Common Stock of
the Company would have been entitled to upon such consolidation, merger or
conveyance; and in any such case appropriate adjustment, as determined by the
Board of Directors of the Company (or successor entity) shall be made as set
forth above with respect to any future changes in the capitalization of the
Company or its successor entity. In the event of the proposed dissolution or
liquidation of the Company, or, except as provided in (b) below, the sale of
substantially all the assets of the Company for other than stock and/or
securities, all outstanding Options under the Plan will automatically terminate,
unless otherwise provided by the Board of Directors of the Company or any
authorized committee thereof.

     (b)  Any Option granted under the Plan, may, at the discretion of the Board
of Directors of the Company and said other corporation, be exchanged for options
to purchase shares of capital stock of another corporation which the Company,
and/or a


                                       9
<PAGE>


subsidiary thereof is merged into, consolidated with, or all or a
substantial portion of the property or stock of which is acquired by said other
corporation or separated or reorganized into. The terms, provisions and benefits
to the optionee of such substitute option(s) shall in all respects be identical
to the terms, provisions and benefits of optionee under his Option(s) prior to
said substitution. To the extent the above may be inconsistent with Sections
424(a)(1) and (2) of the Code, the above shall be deemed interpreted so as to
comply therewith.

     (c)  Any adjustment in the number of shares of Common Stock shall apply
proportionately to only the unexercised portion of the Options granted
hereunder. If fractions of shares of Common Stock would result from any such
adjustment, the adjustment shall be revised to the next higher whole number of
shares of Common Stock.

9.   Further Conditions of Exercise.

     (a)  Unless the shares of Common Stock issuable upon the exercise of an
Option have been registered with the Securities and Exchange Commission pursuant
to the Securities Act of 1933, as amended, prior to the exercise of the Option,
an optionee must represent in writing to the Company that such shares of Common
Stock are being acquired for investment purposes only and not with a view
towards the further resale or distribution thereof, and must supply to the
Company such other documentation as may be required by the Company, unless in
the opinion of counsel to the Company such representation, agreement or
documentation is not necessary to comply with said Act.

     (b)  The Company shall not be obligated to deliver any shares of Common
Stock until they have been listed on each securities exchange on which the
shares of Common Stock may then be listed or until there has been qualification
under or compliance with such state or federal laws, rules or regulations as the
Company may deem applicable.

     (c)  The Board of Directors or Committee may make such provisions and take
such steps as it may deem necessary or appropriate for the withholding of any
taxes that the Company is required by any law or regulation of any governmental
authority, whether federal, state or local, domestic or foreign, to withhold in
connection with the exercise of any Option, including, but not limited to, (i)
the withholding of payment of all or any portion of such Option and/or SAR until
the holder reimburses the Company for the amount the Company is required to
withhold with respect to such taxes, or (ii) the cancelling of any number of
shares of


                                       10
<PAGE>


Common Stock issuable upon exercise of such Option and/or SAR in an amount
sufficient to reimburse the Company for the amount it is required to so
withhold, (iii) the selling of any property contingently credited by the Company
for the purpose of exercising such Option, in order to withhold or reimburse the
Company for the amount it is required to so withhold, or (iv) withholding the
amount due from such employee's wages if the employee is employed by the Company
or any subsidiary thereof.

10.  Termination, Modification and Amendment.

     (a)  The Plan (but not Options previously granted under the Plan) shall
terminate ten (10) years from the earliest of the date of its adoption by the
Board of Directors, or the date the Plan is approved by the stockholders of the
Company, or such date of termination, as hereinafter provided, and no Option
shall be granted after termination of the Plan.

     (b)  The Plan may from time to time be terminated, modified or amended by
the affirmative vote of the holders of a majority of the outstanding shares of
capital stock of the Company entitled to vote thereon.

     (c)  The Board of Directors of the Company may at any time, prior to ten
(10) years from the earlier of the date of the adoption of the Plan by such
Board of Directors or the date the Plan is approved by the stockholders,
terminate the Plan or from time to time make such modifications or amendments of
the Plan as it may deem advisable; provided, however, that the Board of
Directors shall not, without approval by the affirmative vote of the holders of
a majority of the outstanding shares of capital stock of the Company entitled to
vote thereon, increase (except as provided by Paragraph 8) the maximum number of
shares of Common Stock as to which Options or shares may be granted under the
Plan, or materially change the standards of eligibility under the Plan. Any
amendment to the Plan which, in the opinion of counsel to the Company, will be
deemed to result in the adoption of a new Plan, will not be effective until
approved by the affirmative vote of the holders of a majority of the outstanding
shares of capital stock of the Company entitled to vote thereon.

     (d)  No termination, modification or amendment of the Plan may adversely
affect the rights under any outstanding Option without the consent of the
individual to whom such Option shall have been previously granted.


                                       11
<PAGE>


11.  Effective Date of the Plan.

     The Plan shall become effective upon adoption by the Board of Directors of
the Company. The Plan shall be subject to approval by the affirmative vote of
the holders of a majority of the outstanding shares of capital stock of the
Company entitled to vote thereon within one year before or after adoption of the
Plan by the Board of Directors.

12.  Not a Contract of Employment.

     Nothing contained in the Plan or in any option agreement executed pursuant
hereto shall be deemed to confer upon any individual to whom an Option is or may
be granted hereunder any right to remain in the employ of the Company or of a
subsidiary or parent of the Company or in any way limit the right of the
Company, or of any parent or subsidiary thereof, to terminate the employment of
any employee.

13.  Other Compensation Plans.

     The adoption of the Plan shall not affect any other stock option plan,
incentive plan or any other compensation plan in effect for the Company, nor
shall the Plan preclude the Company from establishing any other form of stock
option plan, incentive plan or any other compensation plan.
