upon exercise of either an Option or Stock Purchase Right, shall not be returned

Plan, except that if Shares or Restricted Stock are repurchased by the Company
at their original purchase price, such Shares shall become available for future
grant under the Plan.

     4. ADMINISTRATION OF THE PLAN.

          (a) ADMINISTRATOR. The Plan shall be administered by the Board or a
Committee appointed by the Board, which Committee shall be constituted to
comply with Applicable Laws.

          (b) POWERS OF THE ADMINISTRATOR. Subject to the provisions of the
Plan and, in the case of a Committee, the specific duties delegated by the
Board to such Committee, and subject to the approval of any relevant
authorities, the Administrator shall have the authority in its discretion:

                                       3

<Page>

               (i)    to determine the Fair Market Value;

               (ii)   to select the Service Providers to whom Options and
Stock Purchase Rights may from time to time be grated hereunder;

               (iii)  to determine the number of Shares to be covered by each
such award granted hereunder;

               (iv)   to approve forms of agreement for use under the Plan;

               (v)    to determine the terms and conditions, of any Option or
Stock Purchase Right granted hereunder. Such terms and conditions include,
but are not limited to, the exercise price, the time or times when Options or
Stock Purchase Rights may be exercised (which may be based on performance
criteria), any vesting acceleration or waiver of forfeiture restrictions, and
any restriction or limitation regarding any Option or Stock Purchase Right or
the Common Stock relating thereto, based in each case on such factors as the
Administrator, in its sole discretion, shall determine;

               (vi)   to determine whether and under what circumstances an
Option may be settled in cash under subsection 9(e) instead of Common Stock;

               (vii)  to reduce the exercise price of any Option to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option has declined since the date the Option was granted;

               (viii) to initiate an Option Exchange Program;

               (ix)   to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;

               (x)    to allow Optionees to satisfy withholding tax obligations
by electing to have the Company withhold from the Shares to be issued upon
exercise of an Option or Stock Purchase Right 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
Optionees 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

               (xi)   to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan.

          (c) EFFECT OF ADMINISTRATOR'S DECISION. All decisions, determinations
and interpretations of the Administrator shall be final and binding on all
Optionees.

                                        4

     5. ELIGIBILITY.

          (a) Nonstatutory Stock Options and Stock Purchase Rights may be
granted to Service Providers. Incentive Stock Options may be granted only to
Employees.

          (b) Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair
Market Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year
(under all plans of the Company and any Parent or Subsidiary) exceeds
$100,000, such Options shall be treated as Nonstatutory Stock Options. For
purposes of this Section 5(b), Incentive Stock Options shall be taken into
account in the order in which they were granted. The Fair Market Value of the
Shares shall be determined as of the time the Options with respect to such
Shares is granted.

          (c) Neither the Plan nor any Option or Stock Purchase Right shall
confer upon any Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall it interfere
in any way with his or her right or the Company's right to terminate such
relationship at any time, with or without cause.

     6. TERM OF PLAN. Subject to Section 19 below, the Plan shall become
effective upon its adoption by the Board. It shall continue in effect for a
term of ten (10) years unless sooner terminated under Section 15 of the Plan.

     7. TERM OF OPTION. The term of each Option shall be stated in the Option
Agreement; provided, however, that the term shall be no more than ten (10) years
from the date of grant thereof. In the case of an Incentive Stock Option granted
to an Optionee who, at the time the Option is granted, owns stock representing
more than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the term of the Option shall be five (5)
years from the date of grant or such shorter term as may be provided in the
Option Agreement.

     8. OPTION EXERCISE PRICE AND CONSIDERATION.

          (a) The per share exercise price for the Shares to be issued upon
exercise of an Option shall be such price as is determined by the
Administrator, but shall be subject to the following:

               (i)   In the case of an Incentive Stock Option

                    (A) granted to an Employee who, at the time of grant of such
Option, owns stock representing more than ten percent (10%) of the voting power
of all classes of stock of the Company or any Parent or Subsidiary, the exercise
price shall be no less than 110% of the Fair Market Value per Share on the date
of grant.

                    (B) granted to any other Employee, the per Share exercise
price shall be no less than 100% of the Fair Market Value per Share on the date
of grant.

                                        5
<Page>

               (ii)  In the case of a Nonstatutory Stock Option

                    (A) granted to Service Provider who, at the time of grant
of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or
Subsidiary, the exercise price shall be no less than 110% of the Fair Market
Value per Share on the date of grant.

                    (B) granted to any other Service Provider, the per Share
exercise price shall be no less than 85% of the Fair Market Value per Share
on the date of grant.

               (iii) Notwithstanding the foregoing, Options may be granted
with a per Share exercise price other than as required above pursuant to a
merger or other corporate transaction.

          (b) The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined
by the Administrator (and, in the case of an incentive Stock Option, shall be
determined at the time of grant). Such consideration may consist of (1) cash,
(2) check, (3) promissory note, (4) other Shares which (x) 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 (y) have a Fair Market
Value on the date of surrender equal to the aggregate exercise price of the
Shares as to which such Option shall be exercised, (5) consideration received
by the Company under a cashless exercise program implemented by the Company
in connection with the Plan, or (6) any combination of the foregoing methods
of payment. In making its determination as to the type of consideration to
accept, the Administrator shall consider if acceptance of such consideration
may be reasonably expected to benefit the Company.

     9. EXERCISE OF OPTION.

          (a) PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER. Any Option
granted hereunder shall be exercisable according to the terms hereof at such
times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. Unless the Administrator provides otherwise,
vesting of Options granted hereunder to Officers and Directors shall be
tolled during any unpaid leave of absence. 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 stockholder shall exist
with respect to the Shares, notwithstanding the exercise of the Option. The
Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No

                                       6

<Page>

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.

         Exercise of an Option in any manner shall result in a decrease
in 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, such Optionee may exercise his or her Option
within such period of time as is specified in the Option Agreement (of at least
thirty (30) days) 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 the 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 90 days 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 by the
Administrator, the Option shall terminate and the Shares covered by such Option
shall revert to the Plan.

         In the event an Optionee ceases to be an Employee but remains
a Service Provider, such Employee's Incentive Stock Option shall automatically
convert to a Nonstatutory Stock Option on the date 91 days following such change
of status.

          (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 (of at least 180 days) 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
to the extent the Option is vested on the date of termination for 365 days
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 (of at least 180 days) to the extent that the Option is
vested on the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Option Agreement) by the Optionee's
estate or by a person who acquires the right to exercise the Option by
bequest or inheritance. In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable to the extent the Option is
vested on the date of termination for 365 days following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to the
entire Option, the Shares covered by the unvested portion of the Option shall
immediately revert to the Plan. 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.

                                       7

          (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.

     10. NON-TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS. The Options
and Stock Purchase Rights 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.

     11. STOCK PURCHASE RIGHTS.

          (a) RIGHTS TO PURCHASE. Stock Purchase Rights may be issued either
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan. After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing or electronically of the terms, conditions and restrictions
related to the offer, including the number of Shares that such person shall be
entitled to purchase, the price to be paid, and the time within which such
person must accept such offer. The offer shall be accepted by execution of a
Restricted Stock purchase agreement in the form determined by the Administrator.

          (b) REPURCHASE OPTION. Unless the Administrator determines otherwise,
the Restricted Stock purchase agreement shall grant the Company a repurchase
option exercisable upon the voluntary or involuntary termination of the
purchaser's service with the Company for any reason (including death or
disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock purchase agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at such rate as the
Administrator may determine.

          (c) OTHER PROVISIONS. The Restricted Stock purchase agreement shall
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.

          (d) RIGHTS AS A STOCKHOLDER. Once the Stock Purchase Right is
exercised, the purchaser shall have rights equivalent to those of a stockholder
and shall be a stockholder when his or her purchase is entered upon the records
of the duly authorized transfer agent of the Company. No adjustment shall be
made for a dividend or other right for which the record date is prior to the
date the Stock Purchase Right is exercised, except as provided in Section 12 of
the Plan.

     12. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, MERGER OR ASSET SALE.

          (a) CHANGES IN CAPITALIZATION. Subject to any required action by the
stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Option or Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the plan upon cancellation or expiration of an Option or

                                       8

<Page>

Stock Purchase Right, as well as the price per share of Common Stock covered by
each such outstanding Option of Stock Purchase Right, 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. The 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 convertible into share 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 or Stock Purchase Right.

          (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 or Stock Purchase Right until
fifteen (15) days prior to such transaction as to all of the Optioned Stock
covered thereby, including Shares as to which the Option or Stock Purchase Right
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 or Stock Purchase Right 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 or Stock Purchase Right 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 which does not constitute a "Change of Control" (as
defined in Section 13), or the sale of substantially all of the assets of the
Company, each outstanding Option and Stock Purchase Right 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 or Stock Purchase
Right, the Optionee shall fully vest in and have the right to exercise the
Option or Stock Purchase Right as to all of the Optioned Stock, including Shares
as to which it would not otherwise be vested or exercisable. If an Option or
Stock Purchase Right 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 or Stock
Purchase Right shall be fully exercisable for a period of fifteen (15) days from
the date of such notice, and the Option or Stock Purchase Right shall terminate
upon the expiration of such period. For the purposes of this paragraph, the
Option or Stock Purchase Right 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 subject to the Option or Stock
Purchase Right 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,

                                       9

<Page>

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 or Stock
Purchase Right, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right, 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. VESTING ACCELERATION ON CHANGE OF CONTROL.

          (a) VESTING ACCELERATION. In the event of a "Change of Control,"
(i) all of the Optionee's rights to purchase stock under all stock option
agreements with the Company pursuant to the Plan shall be automatically vested
in their entirety on an accelerated basis and be fully exercisable, and (ii) all
of the Company's rights to repurchase unvested stock under all restricted stock
purchase agreements pursuant to the Plan with the Optionee shall lapse in their
entirety on an accelerated basis:

               (i)   as of the date immediately preceding such "Change of
Control" in the event any such stock option agreement or restricted stock
purchase agreement is or will be terminated or cancel (except by mutual consent)
or any successor to the Company fails to assume and agree to perform the
Company's obligations under all such stock option agreements and restricted
stock purchase agreements; or

               (ii)  as of the date immediately preceding such "Change of
Control" in the event the Optionee does not or will not receive upon exercise of
the Optionee's stock purchase rights under any such stock option agreement or in
exchange for the Optionee's restricted stock acquired pursuant to any such
restricted stock purchase agreement the same identical securities and/or other
consideration as is received by all other stockholders in any merger,
consolidation, sale, exchange or similar transaction occurring upon or after
such "Change of Control"; or

               (iii) as of the date immediately preceding any "Involuntary
Termination" of the Optionee occurring upon or after any such
"Change of Control"; or

"Incumbent Directors." "Incumbent Directors" shall mean directors who either (A)
are directors of the Company as of the date hereof, or (B) are elected, or

objection to such nomination) of at least three-quarters of the Incumbent
Directors at the time of such election or nomination (but shall not include an

threatened proxy contest relating to the election of directors of the Company);
or

               (iii) The stockholders of the Company approve a merger or

          (d) CAUSE. "Cause" shall mean (i) any willful act of personal
dishonesty, fraud or misrepresentation taken by the Optionee in connection with
his or her responsibilities as an employee which was intended to result in

continued failure to substantially perform his or her principal duties and
obligations of employment (other than any such failure resulting from incapacity
due to physical or mental illness), which failure is not remedied in a
reasonable period of time after receipt of written notice from the Company. For
the purposes of this Section 13(d), no act or failure to act shall be considered
"willful" unless

                                       11

done or omitted to be done in bad faith and without reasonable belief that the
act or omission was in or not opposed to the best interests of the Company.

          (e) VOLUNTARY RESIGNATION; TERMINATION FOR CAUSE. If the Optionee's
continuous status as an employee of the Company terminates by reason of the
Optionee's voluntary resignation (and not Involuntary Termination) or if the
Optionee's continuous status as an employee of the Company in terminated for
Cause, in either case prior to such time as accelerated vesting occurs as
provided in Section 13(a) hereof, then the Optionee shall not be entitled to
received accelerated vesting under Section 13(a) hereof.

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.

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 Administrator 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.

     17. 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

                2.  Subsection  (b) of  Section 8 (OPTION  EXERCISE  PRICE AND
CONSIDERATION)  is hereby amended by amending and restating the second  sentence
of such subsection in its entirety to read as follows:

         "Such  consideration  may consist of (1) cash; (2)  certified,  bank or
         cashiers check; (3) money order (4) subject to the prior consent of the
         Board or the  Committee,  surrender of Shares or delivery of a properly

         Administrator  may require  (including  withholding of Shares otherwise
         deliverable upon exercise),  such Shares to have a Fair Market Value on
         the date of surrender or  attestation  equal to the aggregate  exercise
         price of the Shares as to which such  Option  shall be  exercised  (but
         only  to  the  extent  that  such  exercise   would  not  result  in  a
         compensation  charge for financial  reporting  purposes with respect to
         the Shares used to pay the exercise price, unless otherwise  determined
         by the Administrator); (5) subject to the prior consent of the Board or

         regulatory  approval,  a loan  facility to be provided by the  Company)

         to a Company-designated  brokerage firm to effect the immediate sale of

         proceeds  available on the settlement  date,  sufficient funds to cover
         the  aggregate  exercise  price  payable for the Shares;  and (y) shall
         provide written  directions to the Company to deliver the  certificates
         for the Shares directly to such brokerage firm in order to complete the
         sale  transaction;  or (6) any combination of the foregoing  methods of
         payment. In making its determination as to the type of consideration to

         consideration may be reasonably be expected to benefit the Company."

                  3.  Upon the  consummation  of a merger  of the  Company  with

                  4.       Subsection (a) of Section 9 (EXERCISE OF OPTION) is
 hereby amended and restated to read as follows:

         "(a)     PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER.

                  (i)  Any  Option  granted   hereunder   shall  be  exercisable
         according to the terms  hereof at such times and under such  conditions
         as  determined  by the  Administrator  and  set  forth  in  the  Option
         Agreement.  Unless the  Administrator  provides  otherwise,  vesting of
         Options  granted  hereunder to Officers and  Directors  shall be tolled
         during any unpaid leave of absence.  An Option may not be exercised for
         a fraction of a Share.

                  (ii) An Option  shall be  deemed  exercised  when the  Company
         receives:  (A) written or electronic  notice of exercise (in accordance
         with the Option  Agreement and in a form approved by the  Administrator
         from time to time in its sole  discretion)  from the person entitled to
         exercise  the Option,  and (B) 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.

                  (iii) Shares issued upon exercise of an Option shall be issued
         in the name of the  Optionee  or,  if  requested  by the  Optionee  and
         approved by the Administrator in its sole discretion in accordance with
         Applicable Laws, in the name of the Optionee and his or her spouse.

                  (iv)  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  stockholder  shall exist with respect to the
         Shares,  notwithstanding  the exercise of the Option. The Company shall
         issue (or cause to be issued) such Shares  promptly after the Option is
         exercised.

                  (v) 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.

                  (vi) Any right of first refusal (but not the repurchase option
         applicable to unvested Shares) in favor of the Company upon exercise of
         an Option or with  respect  to any Shares  issued  under the Plan shall
         lapse if the  Company or any  successor  in  interest to the Company is
         listed on a national securities exchange or national market system.

                  (vii)  Exercise of an Option in any manner  shall  result in a
         decrease  in 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."

                    PROSPECTIVE AMENDMENT TO 1999 STOCK PLAN

                  The Tantau  Software,  Inc.  1999  Stock Plan (the  "PLAN")
 is hereby  amended  with  respect to options granted from November 20, 2000
under the Plan as follows:

                  1. Subsection (c) of Section 12  (ADJUSTMENTS  UPON CHANGES IN
CAPITALIZATION,  MERGER OR ASSET  SALE) is hereby  amended  and  restated in its
entirety to read as follows:

         "(c)     MERGER OR ASSET SALE.

         (i)  Appropriate  adjustments  in the number of Shares and the exercise
         price  subject  to  each  outstanding  option  shall  be  made  by  the
         Administrator  to give  effect to the  number of Shares of the  Company
         resulting from subdivisions, consolidations or reclassifications of the
         Shares,  the  payment of stock  dividends  by the  Company  (other than
         dividends in the ordinary course) or other changes in the capital stock
         of the Company which the Administrator may, in its discretion, consider
         relevant for purposes of ensuring  that the rights of Optionees are not
         prejudiced thereby (including amalgamations,  mergers, reorganizations,
         liquidations  and  similar  material  transactions),   subject  to  the
         approval,  if required of any stock exchange on which the securities of
         the Company may be listed.

         (ii) If (A) the Company proposes to enter into a transaction that would
         constitute a "Change of Control" (as defined in subsection  (d) of this
         Section 12), (B) the Company  proposes to make an issuer bid for all or
         substantially all holders of shares or proposes to enter into a merger,
         amalgamation or other  corporate  arrangement or  reorganization  or to
         liquidate,  dissolve  or  wind-up;  (C) an  offer  to  purchase  all or
         substantially all of the outstanding shares of the Company is made by a
         third  party;  or (D) there occurs or is proposed a sale or transfer of
         all, or substantially  all, of the  undertaking,  property or assets of
         the Company,  the Board may, with appropriate  notice and in a fair and
         equitable manner, determine the manner in which all outstanding Options
         shall be treated  including,  the acceleration of the expiration of the
         Option  and  of the  exercisability  or  vesting  of  the  Option.  All
         determinations  of the Board under this  paragraph  (ii)  (including  a
         determination that it would be appropriate not to make an adjustment in
         the circumstances) shall be conclusive and final.

         (iii)  Immediately  following the  consummation of a Change of Control,
         all Options shall terminate and cease to be outstanding,  except to the
         extent  assumed by the  successor  corporation  (or parent  thereof) or
         otherwise continued in effect."

                  2.       A new  subsection  (d) is hereby added to Section 12
 of the Plan to read in its entirety as follows:

         the total voting power  represented by the Company's  then  outstanding
         voting securities; or

         (ii) A change  in the  composition  of the  Board of  Directors  of the
         Company as a result of which fewer than a majority of the directors are
         "Incumbent  Directors."  "Incumbent Directors" shall mean directors who
         either (A) are  directors of the Company as of the date hereof,  or (B)
         are elected, or nominated for election,  to the Board of Directors with

         of  the  Company  with  any  other  entity,  other  than  a  merger  or
         consolidation  which  would  result  in the  voting  securities  of the
         Company  outstanding  immediately prior thereto continuing to represent
         (either by  remaining  outstanding  or by being  converted  into voting
         securities of the surviving  entity or such surviving  entity's parent)
         at least fifty percent (50%) of the total voting power  represented  by
         the voting  securities of the Company or such surviving  entity or such

          wholly-owned  subsidiaries),  Section  12 of the  Plan  shall  have no
          further  force  and  effect,  and all  outstanding  Options  shall  be

         (a) If an offer is made to purchase  outstanding  voting  shares of the
         Company and it is accepted  and  completed  in respect of a  sufficient
         number of holders of such shares to  constitute  the offeror  (together
         with such other persons as may be  considered to be "acting  jointly or

          the  voting  stockholders  of the  Company  immediately  prior  to the
          consolidation,  merger or  amalgamation  receive  shares  entitled  to
          exercise  less than 50% of the voting  rights  attaching to the voting
          shares  of  the  consolidated,   merged  or  amalgamated  corporation,

          with  respect to all of the  Shares  subject to the Option and not yet
          purchased thereunder.

                  (b) In  addition,  if an offer is made to purchase 50% or more
         of the  outstanding  voting shares of the Company (the "Offer") and the
         terms of such  Offer  permit  the  tendering  of  Shares  by  notice of
         guaranteed  delivery  or  similar  procedure  in  order to  permit  the
         participation  in such Offer by the holders of Options,  Optionee shall
         have  the  right  to  exercise  his or her  Options  (for  purposes  of
         tendering  to the  Offer) as to the full  amount of Shares  purchasable
         thereunder whether or not then vested, conditional only upon completion
         of the  Offer,  and to  tender  the  Shares  to be  purchased  from the
         Optionee and which are  issuable  pursuant to such Options to the Offer
         by notice of guaranteed  delivery or similar  procedure,  provided that
         arrangements  for payment of the  exercise  price  satisfactory  to the
         Company and in compliance  with  applicable  law and any stock exchange
         requirements  are made, and the Company will take all reasonable  steps
         necessary to facilitate such  conditional  exercise of Options and such
         tender of Shares."

THE PLAN) is hereby amended and restated in its entirety to read as follows:

         "(c) EFFECT OF AMENDMENT OR  TERMINATION.  The Plan, as amended,  shall

EMPLOYMENT AGREEMENT    
  

PARTIES:  

    EMPLOYER: TANNING TECHNOLOGY CORPORATION 

("Tanning"
or "Employer") 

    and

    EMPLOYEE:
Mark Teflian

("Employee") 

AGREEMENT:  

    Employer agrees to hire Employee and Employee accepts employment on the terms and conditions set forth below, which are acknowledged by the parties to be good
and sufficient consideration for this Agreement. 

	1.
	At Will Employment. Employee is employed at will, which means that Employer or Employee may terminate the employment relationship at
any time, with or without prior notice, warning, procedure or formality, for any cause or reason or for no cause or reason. Notwithstanding the foregoing, Employee is entitled to the severance and
acceleration of vesting of stock options set forth in Section 4 of the Employee Term Sheet under the circumstances and subject to the qualifications described therein.

	2.
	Position/Compensation/Benefits. Employee's position, compensation and benefits are specified in the attached Employee Term Sheet.

	3.
	Duties/Best Efforts. Employee agrees to devote Employee's full professional time and attention to the business of Employer and those
duties and obligations entrusted to Employee and/or as specified by Employee's supervisor or superiors from time to time. Employee shall at all times perform Employee's duties faithfully,
industriously and to the best of Employee's ability, experience and talent.

	4.
	Confidentiality, Non-Disclosure and Proprietary Rights.

	a.
	Employee
understands and agrees that the following classes of information (collectively "Confidential Information"), whether or not in writing and whether or not formally marked,
are and shall remain the exclusive and confidential property of the Employer:

	•
	data,
software, processes, client contacts, client/customer lists, service techniques, market development and expansion plans, personnel training and
development methods, internal business organization and methods, "Inventions" (as defined below), and other technical, business and financial information which gives Employer a competitive advantage
in its business

	•
	information
and data provided to Employer from time to time by third parties on the understanding and condition that such data and information will be kept
confidential and will not be disclosed to any entity or person not authorized by such third party

	•
	ideas,
processes, software, information, data, or other items that may be developed by Employee from time to time as work product of the employment
relationship 

Any
information which is generally known to the public will not be deemed Confidential Information. 

	b.
	Throughout
the time Employee is employed by Employer (the "Period of Employment"), and thereafter, Employee will not use or disclose Confidential Information, and will take all
reasonable precautions to prevent any person or entity access to any of the Confidential 

Information,
other than as required in the performance of Employee's duties with Employer. In order to satisfy the needs of Employer's clients and customers, Employee will sign any confidentiality
agreement reasonably requested by such third parties and/or Employer. Employee understands that he/she is not permitted to use the Confidential Information for his/her own purposes or benefit. 

	c.
	Except
in the performance of Employee's duties to Employer, Employee shall not duplicate in any way or remove from the work premises any property of Employer or its business
associates, including but not limited to any Confidential Information. At the end of the Employee's Period of Employment, Employee will deliver to Employer all such property, including all copies of
materials embodying Confidential Information, and including, without limitation, files contained on paper, electronic, optical or other media.

	d.
	Employee
hereby agrees to assign, and does hereby assign, all of Employee's right, title and interest in or to any and all ideas, concepts, know-how, techniques,
processes, inventions, discoveries, developments, software, works of authorship, innovations and improvements (collectively "Inventions") conceived or made by Employee during Employee's Period of
Employment, whether alone or in concert with others, whether patentable or subject to potential copyrights or not, except those that the Employee developed or develops entirely on Employee's own time
without using the equipment, supplies, facilities, or Confidential Information of the Employer, and provided that such Inventions are unrelated to the business of the Employer. Employee agrees to
promptly inform and disclose all Inventions to the Employer in writing, and with respect to those Inventions that Employee is required to assign to the Employer hereunder, to provide all assistance
reasonably requested by the Employer in the preservation of its interests in the Inventions (such as by making applications, executing documents, testifying, etc.), such assistance to be provided at
the Employer's expense but without additional compensation to the Employee. Employee agrees that all such Inventions are Confidential Information and are the sole and absolute property of Employer.

	e.
	Employee
agrees that any work or Invention prepared by the Employee during Employee's Period of Employment which is subject to assignment under paragraph (d) above,
and which is eligible for United States copyright protection or protection under the Universal Copyright Convention, the Berne Copyright Convention and/or the Buenos Aires Copyright Convention shall
be a "work made for hire" and the sole and absolute property of Employer. In the event that any such work is deemed not to be a "work made for hire", Employee hereby assigns all right, title and
interest in and to the copyright in such work to the Employer, and agrees to provide all assistance reasonably requested in the establishment, preservation and enforcement of the Employer's copyright
in such work, such assistance to be provided at the Employer's expense but without any additional compensation to Employee.

	f.
	In
the event that the Employer is unable, as a result of inability to find the Employee after a reasonably diligent effort, as a result of the death or incapacity of the Employee,
or as a result of the unjustifiable refusal of the Employee, to secure the Employee's signature on any documents, applications, or letters patent, copyright or other analogous protection relating to
Inventions or other proprietary rights, the Employee hereby irrevocably designates and appoints Employer, by its duly authorized officers and agents as the Employee's agent and
attorney-in-fact, to act for and on the Employee's behalf and stead to execute and file any such application or applications and to do all other
lawfully permitted acts to further the prosecution and issuance of letters patent, copyright, or other analogous protection thereon with the same legal force and effect as if executed by the Employee. 

	5.
	Non-Competition Covenant and Agreement. Employee holds an executive position with Employer in which Employee manages
portions of the business operations of Employer and supervises or oversees other employees. Employee is considered a key employee of Employer whose efforts are integral to Employer's business and for
which Employee receives commensurately high compensation and benefits. Employer has invested and/or will invest considerable time and money 

in
the development and enhancement of Employee's education, training and skills and the knowledge of Employer's unique business, which business is worldwide in scope and market. This enhanced skill
and knowledge is a substantial asset of Employer and will be the principal reason that Employer continues the employment relationship and continues to compensate Employee for Employee's work. In
addition, Employee has or will become aware of the Confidential Information including the Trade Secrets, trade practices, and customer lists/names of Employer, which Confidential Information in the
hands of a competitor or potential competitor would cause substantial loss and damage to Employer and/or its customers and clients. Finally, Employee will have close customer contact, which would
enable Employee to divert customer trade. Employee acknowledges that Employee's employment creates a relationship of confidence and trust between Employer and Employee with respect to the Confidential
Information of Employer, its affiliates, customers and clients. Employee also acknowledges the highly competitive nature of Employer's business. In consideration of the above matters, Employee agrees
and acknowledges that it is reasonable, necessary and appropriate in order to protect the immediate interests of and avoid substantial injury to Employer for Employee to accept restrictions on
Employee's right to work or be employed in a fashion which will compete with Employer's business and type of business. 

Therefore,
Employee covenants, agrees to, and accepts the following restrictions: 

	a.
	Employee
will not, alone or in concert or cooperation with any other person or entity, as owner, manager, principal, employee, investor, shareholder, consultant, or any other type
of operator or advisor, directly or indirectly, engage in the business of, develop, seek to develop, market, produce or provide any commercial product or service provided by, or under development by
Employer or any of its affiliates during the Period of Employment. This non-competition obligation shall apply to North America, Europe, and any other country where Employer or any of its
subsidiaries or affiliates are actively engaged in or pursuing business during the Employee's Period of Employment. This paragraph (a) shall not prohibit the ownership by Employee of
less than 5% of any publicly traded corporation, provided that Employee is not otherwise engaged with such corporation in any of the activities prohibited by this paragraph 5. The restriction
set forth in this paragraph (a) shall be in effect during the Period of Employment and for one year after the termination of employment for any reason; provided, however, that if such
employment is terminated by Employer without cause during the first year of employment, this restriction will be in effect during the Period of Employment, and thereafter for a number of days
equal to the length of the employment.

	b.
	Employee
will not, during the Period of Employment, and for one year after the termination of employment for any reason, directly or indirectly, (1) hire an employee,
consultant, agent or representative of Employer or its affiliates, successors or assigns or solicit the employment or services of any person who is employed by Employer or its successors or assigns,
or any former employee of the Employer whose employment has been terminated for less than six (6) months; or (2) solicit, directly or indirectly, the business of, or business competitive
with the Employer's then current business with, any customer or client of the Employer. The above shall not prohibit the Employee from using the services of any such person in a way that clearly does
not compete with the business of Employer.

	c.
	The
time periods of the restrictions set forth in paragraphs (a) and (b) above shall be extended for any period of time that Employee is found to be in violation of
any provision of this paragraph 5. 

If
any court shall determine that the duration, geographic limitations, subject or scope of any restriction contained in this paragraph 5 is unenforceable, it is the intention of the parties
that this paragraph 5 shall not thereby be terminated but shall be deemed amended to the extent required to make it valid and enforceable, such amendment to apply only with respect to the
operation of this paragraph 5 in the jurisdiction of the court that has made the adjudication. 

	6.
	Affiliated Entities. Employee understands that Employer's business may be carried out by or in conjunction with affiliated companies
or subsidiaries. Employee agrees that Employee's obligations 

of
confidentiality and non-competition shall apply equally to the Confidential Information, business and employees of Employers' subsidiaries and affiliates. For such purposes, any
reference to Employer or Tanning in this Agreement shall also be deemed to be a reference to its subsidiaries and affiliates. 

	7.
	Remedies for Breach of Non-Disclosure/Non-Compete Provisions. Employee acknowledges and agrees that the
provisions of this Agreement are essential to the Employer and are reasonable and necessary to protect the legitimate interests of the Employer and its affiliates and that the damages sustained by the
Employer or its affiliates as a result of a breach of the agreements contained herein will subject the Employer or its affiliates to immediate, irreparable harm and damage, the amount of which,
although substantial, cannot be reasonably ascertained, and that recovery of damages at law will not be an adequate remedy. Employee therefore agrees that the Employer and its affiliates, in addition
to any other remedy they may have under this Agreement or at law, shall be entitled to injunctive and other equitable relief to prevent or curtail any breach of any provision of this Agreement. In the
event suit or action is instituted to enforce this Agreement or any of the terms and conditions hereof, including, but not limited to, suit for a temporary restraining order or preliminary or
permanent injunction, the prevailing party shall be entitled to costs and reasonable attorneys' fees. Employee waives any right to the posting of a bond in the event of an issuance of a temporary
restraining order, preliminary
injunction or permanent injunction upon the issuance of such an order by a court of competent jurisdiction.

	8.
	Employee Notification Requirement. During the Period of Employment, and thereafter during any subsequent period of time that the
Employee is reasonably likely to be subject to a continuing obligation under the terms of this Agreement, the Employee will notify the Employer of any change of address, and the Employee will identify
and notify the Employer of each and any new job or other business activity in which the Employee plans to engage, together with the name and address of the new employer and a reasonably detailed
description of the nature of the Employee's new position with such new employer sufficient for Employer to be able to enforce its rights under this Agreement.

	9.
	Former Employment or Work. Employee represents, acknowledges and agrees that Employee has not brought, and will not bring with
Employee, or use in the performance of Employee's duties for the Employer, any materials or documents of any former employer, client, person, or entity of any type, which are not generally available
to the public, unless the Employee has obtained written authorization for the possession and use of such materials or documents and provided such authorization to Employer. Employee also understands
and agrees, that in Employee's employment with the Employer, Employee shall not breach any obligation of confidentiality or legal duty that Employee has to any former employer or client and agrees
that Employee will fulfill any and all such obligations during Employee's Period of Employment. Employee agrees to indemnify and hold Employer harmless with respect to any breach of this provision
pursuant to the terms of paragraph 11 below.

	10.
	Assignment. This Agreement, and the duties, obligations and benefits hereunder shall bind and benefit the parties hereto, and to the
extent necessary to carry out its intentions, the legal and personal representatives of the parties. This Agreement may not be assigned without the written permission of the parties, except that the
Employer may assign this Agreement to any successor of the Employer by reason of reorganization, merger, consolidation, or the partial or complete sale of the Employer's business and/or assets.

	11.
	Indemnification and Remedy. Each party agrees to indemnify and hold harmless the other against any and all damages, claims, losses or
expenses, including reasonable attorney's fees, arising from or relating to any breach of this Agreement.

	12.
	Entire Agreement and Amendment. This Agreement, including the attached Employee Term Sheet which is incorporated by this reference,
constitutes the entire agreement between the Employer and Employee, and any verbal or written communication between the parties prior to the adoption of this Agreement, including any offer letter from
Employer to Employee, shall be deemed merged 

herein and of no further force and effect. Notwithstanding the foregoing, however, Employee shall continue to be liable for the veracity of any representations concerning Employee made in connection
with his or her job application to Employer. This Agreement supersedes any conflicting policies relating to Tanning employees. Except as provided in the attached Employee Term Sheet, this Agreement
may only be altered or amended by a writing signed by the Employee and an authorized officer of the Employer and no officer, employee, agent or representative of Tanning has the authority to orally
modify any term of this Agreement including, without limitation, the at-will nature of Employee's employment. 

	13.
	Waiver. Neither the delay nor failure by the Employer or Employee to enforce any provision or exercise any right under this
Agreement, nor partial or single enforcement or exercise of any such provision or right, shall constitute a waiver of that or any other provision or right.

	14.
	Governing Law and Venue. This Agreement is entered into in Denver, Colorado, and as such it shall be interpreted and enforced under
the laws of the State of Colorado applicable to contracts made to be performed entirely within Colorado. Except as necessary to enforce Employer's rights pursuant to paragraphs 4 through 7 above, to
the extent that any action is brought in a court of law in connection with this Agreement, the exclusive venue for such action shall be a court of appropriate jurisdiction, including the Federal
courts, located in the City and County of Denver, Colorado.

	15.
	Interpretation. In the event that any one or more provision in this Agreement shall, for any reason, be held to be invalid, illegal,
or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision of this Agreement, but this Agreement shall be construed as if such provision had
never been contained herein. If any provision in this Agreement shall be held to be excessively broad as to duration, activity or subject in any jurisdiction, it shall be construed by limiting and
reducing the provision which is deemed excessively broad. A limitation or reduction in the application of any provision in one jurisdiction shall not affect the application of the same provision in
any other jurisdiction.

	16.
	Notices. Any notice required or permitted by this Agreement shall be effective when received, and shall be sufficient if in writing
and personally delivered (including by express courier) or sent by certified mail with return receipt to the address set forth at the end of this Agreement or at such other address as may by notice be
specified by one party to the other.

	17.
	Survival. The provisions of this Agreement which by their nature are intended to survive, including without limitation the
confidentiality, non-disclosure, non-competition, non-solicitation and indemnification provisions, shall survive the termination of this Agreement.

	18.
	Arbitration. Except with respect to an action by Employer to seek to enforce its legal or equitable rights pursuant to paragraphs 4
through 7 above, and after the exhaustion of all applicable administrative remedies, any controversy or claim arising out of or related to this Agreement shall be resolved by arbitration in Colorado
under the Commercial Rules of the American Arbitration
Association in effect at the time such controversy or claim arises (the "Rules") by one arbitrator appointed by the American Arbitration Association in accordance with its Rules, except that the
parties specifically authorize the Arbitrator to set a schedule for, accept the submission of and dispositively rule on any or all of the issues raised in motion(s) and supporting briefs for summary
judgment prior to conducting any such arbitration. The arbitrator shall apportion the costs of arbitration. The award of the arbitrator shall be in writing, shall be final and binding upon the
parties, shall not be appealed from or contested in any court and may, in appropriate circumstances, include injunctive relief. Should any party fail to appear or be represented at the arbitration
proceedings after due notice in accordance with the Rules, then the arbitrator may nevertheless render a decision in the absence of that party, and such decision shall have the same force and effect
as if the absent party had been present, whether or not it shall be adverse to the interests of that party. Any award rendered hereunder may be entered for enforcement, if necessary, in any court of
competent jurisdiction, and the party against whom enforcement is sought shall bear the expenses, including attorneys' fees, of enforcement. 

	19.
	Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which
shall together constitute one and the same Agreement. 

Employee accepts employment with Employer on the above-terms and acknowledges by Employee's signature below that Employee is employed at-will, which means that
either Employer or Employee may terminate the employment relationship at any time, with or without prior notice, warning, procedure or formality, for any cause or reason or for no cause or
reason.
