               (vi) to determine the terms and conditions, not inconsistent with

discretion, shall determine;

by such Option shall have declined since the date the Option was granted;

               (viii) to institute an Option Exchange Program;

the Administrator;

by electing to have the Company withhold from the Shares to be issued upon
exercise of an Option that number of Shares having a Fair Market Value equal to
the amount required to be withheld. The Fair Market Value of the Shares to be
withheld shall be determined on the date that the amount of tax to be withheld
is to be determined. All elections by an Optionee to have Shares withheld for
this purpose shall be made in such form and under such conditions as the
Administrator may deem necessary or advisable; and

               (xv) to make all other determinations deemed necessary or
advisable for administering the Plan.

         (c) Effect of Administrator's Decision. The Administrator's decisions,
determinations and interpretations shall be final and binding on all Optionees

     5. Eligibility. Options may be granted to Service Providers; provided,
however, that notwithstanding anything to the contrary contained in the Plan,
Options may not be granted to any Officer or Director of the Company.

     6. Limitation. Neither the Plan nor any Option shall confer upon an
Optionee any right with respect to continuing the Optionee's relationship as a
Service Provider with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

     7. Term of Plan. The Plan shall become effective upon its adoption by the
Board. It shall continue in effect for ten (10) years, unless sooner terminated
under Section 14 of the Plan.

     8. Term of Option. The term of each Option shall be stated in the Option
Agreement.

     9. Option Exercise Price and Consideration.

         (a) Exercise Price. The per share exercise price for the Shares to be
issued pursuant to exercise of an Option shall be determined by the
Administrator.

         (b) Waiting Period and Exercise Dates. At the time an Option is
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised.

         (c) Form of Consideration. The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment. Such consideration may consist entirely of:

               (i) cash;

               (ii) check;

               (iii) other Shares which (A) in the case of Shares acquired upon
exercise of an option, have been owned by the Optionee for more than six months
on the date of surrender, and (B) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised;

               (iv) consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan;

               (v) a reduction in the amount of any Company liability to the
Optionee, including any liability attributable to the Optionee's participation
in any Company-sponsored deferred compensation program or arrangement;

               (vi) such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws; or

                                      -5-
<PAGE>   6

               (vii) any combination of the foregoing methods of payment.

     10. Exercise of Option.

         (a) Procedure for Exercise; Rights as a Shareholder. Any Option granted
hereunder shall be exercisable according to the terms of the Plan and at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement. An Option may not be exercised for a fraction of a
Share.

             An Option shall be deemed exercised when the Company receives: (i)
written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 12 of the Plan.

             Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

         (b) Termination of Relationship as a Service Provider. If an Optionee
ceases to be a Service Provider, other than upon the Optionee's death or
Disability, the Optionee may exercise his or her Option, but only within such
period of time as is specified in the Option Agreement, and only to the extent
that the Option is vested on the date of termination (but in no event later than
the expiration of the term of such Option as set forth in the Option Agreement).
In the absence of a specified time in the Option Agreement, the Option shall
remain exercisable for three (3) months following the Optionee's termination.
If, on the date of

                                      -6-
<PAGE>   7

termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified by the Administrator, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

         (c) Disability of Optionee. If an Optionee ceases to be a Service
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option
Agreement, to the extent the Option is vested on the date of termination (but in
no event later than the expiration of the term of such Option as set forth in
the Option Agreement). In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable for twelve (12) months following
the Optionee's termination. If, on the date of termination, the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan. If, after termination, 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 the Plan.

         (d) Death of Optionee. If an Optionee dies while a Service Provider,
the Option may be exercised within such period of time as is specified in the
Option Agreement (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant), by the Optionee's estate or by a
person who acquires the right to exercise the Option by bequest or inheritance,
but only to the extent that the Option is vested on the date of death. In the
absence of a specified time in the Option Agreement, the Option shall remain
exercisable for twelve (12) months following the Optionee's termination. If, at
the time of death, the Optionee is not vested as to his or her entire Option,
the Shares covered by the unvested portion of the Option shall immediately
revert to the Plan. The Option may be exercised by the executor or administrator
of the Optionee's estate or, if none, by the person(s) entitled to exercise the
Option under the Optionee's will or the laws of descent or distribution. If the
Option is not so exercised within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

         (e) Buyout Provisions. The Administrator may at any time offer to buy
out for a payment in cash or Shares, an Option previously granted based on such
terms and conditions as the Administrator shall establish and communicate to the
Optionee at the time that such offer is made.

     11. Non-Transferability of Options. Unless determined otherwise by the
Administrator, an Option may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee. If the Administrator makes an Option
transferable, such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

     12. Adjustments Upon Changes in Capitalization, Dissolution, Merger or
Asset Sale.

         (a) Changes in Capitalization. Subject to any required action by the
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities

                                      -7-
<PAGE>   8

convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of shares
of Common Stock subject to an Option.

         (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated. To the extent it has not been previously exercised, an
Option will terminate immediately prior to the consummation of such proposed
action.

         (c) Merger or Asset Sale. In the event of a merger of the Company with
or into another corporation, or the sale of substantially all of the assets of
the Company, each outstanding Option shall be assumed or an equivalent option or
right substituted by the successor corporation or a Parent or Subsidiary of the
successor corporation. In the event that the successor corporation refuses to
assume or substitute for the Option, the Optionee shall fully vest in and have
the right to exercise the Option as to all of the Optioned Stock, including
Shares as to which it would not otherwise be vested or exercisable. If an Option
becomes fully vested and exercisable in lieu of assumption or substitution in
the event of a merger or sale of assets, the Administrator shall notify the
Optionee in writing or electronically that the Option shall be fully vested and
exercisable for a period of fifteen (15) days from the date of such notice, and
the Option shall terminate upon the expiration of such period. For the purposes
of this paragraph, the Option shall be considered assumed if, following the
merger or sale of assets, the option or right confers the right to purchase or
receive, for each Share of Optioned Stock, immediately prior to the merger or
sale of assets, the consideration (whether stock, cash, or other securities or
property) received in the merger or sale of assets by holders of Common Stock
for each Share held on the effective date of the transaction (and if holders
were offered a choice of consideration, the type of consideration chosen by the
holders of a majority of the outstanding Shares); provided, however, that if
such consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option, for each Share of Optioned Stock to be
solely common stock of the successor corporation or its Parent equal in fair
market value to the per share consideration received by holders of Common Stock
in the merger or sale of assets.

     13. Date of Grant. The date of grant of an Option shall be, for all
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is determined by the Administrator.
Notice of the determination shall be provided to each Optionee within a
reasonable time after the date of such grant.

     14. Amendment and Termination of the Plan.

                                      -8-
<PAGE>   9

         (a) Amendment and Termination. The Board may at any time amend, alter,
suspend or terminate the Plan.

         (b) Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to options granted under the
Plan prior to the date of such termination.

     15. Conditions Upon Issuance of Shares.

         (a) Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

         (b) Investment Representations. As a condition to the exercise of an
Option the Company may require the person exercising such Option to represent
and warrant at the time of any such exercise that the Shares are being purchased
only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company, such a representation is
required.

     16. Inability to Obtain Authority. The inability of the Company to obtain
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder, shall relieve the Company of any liability in respect
of the failure to issue or sell such Shares as to which such requisite authority
shall not have been obtained.

     17. Reservation of Shares. The Company, during the term of this Plan, will
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

            b) Method of Exercise. This Option is exercisable by delivery of an
exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan. The Exercise Notice shall be completed
by the Optionee and delivered to the Company. The Exercise Notice shall be
accompanied by payment of the aggregate Exercise Price as to all Exercised
Shares. This Option shall be deemed to be exercised upon receipt by the Company
of such fully executed Exercise Notice accompanied by such aggregate Exercise
Price.

            No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with Applicable Laws. Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

         3. Method of Payment. Payment of the aggregate Exercise Price shall be
by any of the following, or a combination thereof, at the election of the
Optionee:

            (a) cash;

            (b) check;

                                      -2-
<PAGE>   12

            (c) consideration received by the Company under a cashless exercise
program implemented by the Company in connection with the Plan; or

            (d) surrender of other Shares, provided Shares acquired from the
Company, (i) have been owned by the Optionee for more than six (6) months on the
date of surrender, AND (ii) have a Fair Market Value on the date of surrender
equal to the aggregate Exercise Price of the Exercised Shares.

         4. Non-Transferability of Option. This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by the Optionee. The terms
of the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

         5. Term of Option. This Option may be exercised only within the term
set out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option Agreement.

         6. Tax Consequences. Some of the federal tax consequences relating to
this Option, as of the date of this Option, are set forth below. THIS SUMMARY IS
NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR
DISPOSING OF THE SHARES.

            (a) Exercising the Option. The Optionee may incur regular federal
income tax liability upon exercise of an NSO. The Optionee will be treated as
having received compensation income (taxable at ordinary income tax rates) equal
to the excess, if any, of the Fair Market Value of the Exercised Shares on the
date of exercise over their aggregate Exercise Price. If the Optionee is an
Employee or a former Employee, the Company will be required to withhold from his
or her compensation or collect from Optionee and pay to the applicable taxing
authorities an amount in cash equal to a percentage of this compensation income
at the time of exercise, and may refuse to honor the exercise and refuse to
deliver Shares if such withholding amounts are not delivered at the time of
exercise.

            (b) Disposition of Shares. If the Optionee holds NSO Shares for at
least one year, any gain realized on disposition of the Shares will be treated
as long-term capital gain for federal income tax purposes.

         7. Entire Agreement; Governing Law. The Plan is incorporated herein by
reference. The Plan and this Option Agreement constitute the entire agreement of
the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof, and may not be modified adversely to the
Optionee's interest except by means of a writing signed by the Company and
Optionee. This agreement is governed by the internal substantive laws, but not
the choice of law rules, of Colorado.

THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED
ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (AND NOT

                                      -4-
<PAGE>   8

holder of such Company Stock Certificate shall be entitled to receive from the
Exchange Agent in exchange therefor a certificate representing the number of
whole shares of Parent Common Stock to which such holder is entitled pursuant to
Section 1.6, and the Company Stock Certificate so surrendered shall be canceled.
Until so surrendered, each outstanding Company Stock Certificate will be deemed
for all corporate purposes, to evidence only the ownership of the number of full
shares of Parent Common Stock into which such shares of Company Common Stock
shall have been so converted.

            (d) Distributions With Respect to Unexchanged Shares. No dividends
or other distributions declared or made after the Effective Time with respect to
Parent Common Stock with a record date after the Effective Time will be paid to
the holder of any unsurrendered Company Stock Certificate with respect to the
shares of Parent Common Stock represented thereby until the holder of record of
such Company Stock Certificate shall surrender such Certificate. Subject to
applicable law, following surrender of any such Company Stock Certificate, there
shall be paid to the record holder of the certificates representing whole shares
of Parent Common Stock issued in exchange therefor, without interest, at the
time of such surrender, the amount of dividends or other distributions with a
record date after the Effective Time theretofore paid with respect to such whole
shares of Parent Common Stock.

            (e) Transfers of Ownership. If any certificate for shares of Parent
Common Stock is to be issued in a name other than that in which the certificate
surrendered in exchange therefor is registered, it will be a condition of the
issuance thereof that the certificate so surrendered will be properly endorsed
and otherwise in proper form for transfer and that the person requesting such
exchange will have paid to Parent or any agent designated by it any transfer or
other taxes required by reason of the issuance of a certificate for shares of
Parent Common Stock in any name other than that of the registered holder of the
certificate surrendered, or established to the satisfaction of Parent or any
agent designated by it that such tax has been paid or is not payable.

            (f) No Liability. Notwithstanding anything to the contrary in this
Section 1.7, neither the Exchange Agent, the Surviving Corporation nor any party
hereto shall be liable to a holder of shares of Company Common Stock for any
amount properly paid to a public official pursuant to any applicable abandoned
property, escheat or similar law.

         1.8 No Further Ownership Rights in Company Common Stock. The shares of
Parent Common Stock paid in respect of the surrender for exchange of shares of
Company Common Stock in accordance with the terms hereof, shall be deemed to be
full satisfaction of all rights pertaining to such shares of Company Common
Stock, and there shall be no further registration of transfers on the records of
the Surviving Corporation of shares of Company Common Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Company Stock Certificates are presented to the Surviving Corporation for
any reason, they shall be canceled and exchanged as provided in this Article I.

         1.9 Lost, Stolen or Destroyed Certificates. In the event any
certificates evidencing shares of Company Common Stock shall have been lost,
stolen or destroyed, the Exchange Agent shall

                                      -5-
<PAGE>   9

issue in exchange for such lost, stolen or destroyed certificates, upon the
making of an affidavit of that fact by the holder thereof, such amount, if any,
as may be required pursuant to Section 1.6 hereof; provided, however, that
Parent may, in its discretion and as a condition precedent to the issuance
thereof, require the Stockholder who is the owner of such lost, stolen or
destroyed certificates to deliver a bond in such amount as it may reasonably
direct against any claim that may be made against Parent or the Exchange Agent
with respect to the certificates alleged to have been lost, stolen or destroyed.

         1.10 Taking of Necessary Action; Further Action. If at any time after
the Effective Time, any further action is necessary or desirable to carry out
the purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of the Company, Parent, Sub, and the officers and directors of
the Company, Parent and Sub are fully authorized in the name of their respective
corporations or otherwise to take, and will take, all such lawful and necessary
action.

     6.2 Recovery For Losses.

         (a) Indemnification. The Stockholder agrees to indemnify and hold
Parent and its officers, directors and affiliates harmless against all claims,
losses, liabilities, damages, deficiencies, costs and expenses, including
reasonable attorneys' fees and expenses of investigation and defense (including,
without limitation, indirect and consequential damages) (hereinafter
individually a "LOSS" and collectively "LOSSES") incurred by Parent, its
officers, directors, or affiliates (including the Surviving Corporation)
(collectively, the "INDEMNIFIED PARTIES") directly or indirectly as a result of
any inaccuracy or breach of a representation or warranty of the Company
contained in this Agreement or in any certificate, instrument or other document
delivered by Company pursuant to the terms of this Agreement, any failure by the
Company to perform or comply with any covenant

contained herein. Nothing herein shall limit the liability of the Parent, the
Company or Stockholder for any breach of any representation, warranty or
covenant if the Merger does not close. The Stockholder shall not have any right
of contribution from the Company or Parent with respect to any Loss pursuant to
this Article VI. Any claims for Losses must be made on or before the Termination
Date.

         (b) Limitations on Indemnification. Except (i) as to any inaccuracy or
breach of a representation or warranty contained in Section 2.2 and Section 2.9
hereof and (ii) for claims based on fraud, in the event the Merger is
consummated, the maximum amount that the Indemnified Parties may recover for
losses under this Agreement shall be the Aggregate Consideration and the
Additional Consideration, if such Additional Consideration is paid by Parent. In
the event of (i) any inaccuracy or breach of a representation or warranty
contained in Section 2.2 and Section 2.9 hereof, or (ii) any claim based on
fraud, the Indemnified Parties may recover any and all losses from the
Stockholder without limitation. Notwithstanding any provision of this Agreement
to the contrary, after the Effective Time Parent shall not be entitled to
indemnification until it has recognized Losses in excess of $50,000 in the
aggregate, in which case Parent shall be entitled to recover for all Losses in
excess of $50,000.

     7.4 Entire Agreement; Assignment. This Agreement, the Exhibits hereto, the
Disclosure Schedule, the Confidential Disclosure Agreement, and the documents
and instruments and other agreements among the parties hereto referenced herein:
(i) constitute the entire agreement among the parties with respect to the
subject matter hereof and supersede all prior agreements and understandings both
written and oral, among the parties with respect to the subject matter hereof,
(ii) are not intended to confer upon any other person any rights or remedies
hereunder and (iii) shall not be assigned by operation of law or otherwise,
except that Parent may assign its rights and delegate its obligations hereunder
to its affiliates as long as Parent remains ultimately liable for all of
Parent's obligations hereunder.

     7.5 Severability. In the event that any provision of this Agreement or the
application thereof, becomes or is declared by a court of competent jurisdiction
to be illegal, void or unenforceable, the remainder of this Agreement will
continue in full force and effect and the application of such provision to other
persons or circumstances will be interpreted so as reasonably to effect the
intent of the parties hereto. The parties further agree to replace such void or
unenforceable provision of this Agreement with a valid and enforceable provision
that will achieve, to the extent possible, the economic, business and other
purposes of such void or unenforceable provision.

     7.6 Other Remedies. Any and all remedies herein expressly conferred upon a
party will be deemed cumulative with and not exclusive of any other remedy
conferred hereby, or by law or equity upon such party, and the exercise by a
party of any one remedy will not preclude the exercise of any other remedy.

     7.7 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
Each of the parties hereto irrevocably consents to the exclusive jurisdiction
and venue of any court within New York County, State of New York, in connection
with any matter based upon or arising out of this Agreement or the matters
contemplated herein, agrees that process may be served upon them in any manner
authorized by the laws of the State of New York for such persons and waives and
covenants not to assert or plead any objection which they might otherwise have
to such jurisdiction, venue and such process. Each of the parties hereto
irrevocably waives such person's right to a jury trial of any claim or cause of
action arising out of this Agreement or any of the transactions contemplated
hereby and waives and covenants not to assert or plead any objection which such
person might otherwise have to such waiver of jury trial.

     7.8 Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.
