Affiliated Group;

            WHEREAS, B/E Aerospace files certain Combined Returns on behalf of

and future subsidiaries (collectively, the "B/E Aerospace Subgroup"), and ATT,
on behalf of itself and its present and future subsidiaries (collectively, the
"ATT Subgroup") to provide for the allocation and apportionment between the B/E
Aerospace Subgroup and the ATT Subgroup of responsibilities, liabilities, and

            2.1       Consent to File. ATT hereby consents to the filing of
Consolidated Group Returns by B/E Aerospace on behalf of the Affiliated Group,
including ATT and the ATT Subgroup, for each Consolidated Return Year, and to
any applications for extensions of time to file such Returns, which B/E
Aerospace in its sole judgment shall make to the IRS. ATT hereby consents to the

including ATT and the ATT Subgroup, for each Combined Return Year, and to any
applications for extensions of time to file such Returns, which B/E Aerospace in

responsible for filing all Tax Returns for the ATT Subgroup for any Taxable year
or portion thereof that is not a Consolidated Return Year or Combined Return
Year, as the case may be.

            2.2       Responsibility for Preparing and Filing. B/E Aerospace
shall be entitled to prepare and file, and shall be responsible for the
preparation and filing, of the Consolidated Group Returns and any Combined
Returns, including but not limited to determining all Tax Return positions,
paying estimated taxes and other consolidated Taxes and making all federal,

extensions, for filing such Tax Return. B/E may, in its sole and absolute
discretion, determine whether to incorporate any such comments in such Tax
Return.

<PAGE>   6

            2.3       Further Action. ATT agrees, at B/E Aerospace's request,
to furnish to B/E Aerospace and/or any Taxing Authority any and all information
and to execute all elections and other documents which may be necessary or
appropriate, in the judgment of B/E Aerospace, to evidence ATT's consent or to
facilitate the preparing and filing of such Returns and applications for
extension of time to file such Returns. This obligation applies to all Tax
Returns for any Consolidated Return Year or Combined Return Year even if such
Return is filed after ATT is no longer a member of the Affiliated Group or the
Combined Group.

3. INDEMNITY, ALLOCATION AND PAYMENT OF LIABILITIES FOR TAXES

            3.1       Indemnities.

            (a) B/E Aerospace shall be responsible for, and indemnify and hold
ATT and the ATT Subgroup harmless for, any Taxes not allocable to ATT and the
ATT Subgroup pursuant to this Article 3 for any Consolidated Return Year or
Combined Return Year.

            (b) ATT shall be responsible for, and indemnify and hold B/E
Aerospace and the B/E Aerospace Subgroup harmless for, any Taxes allocable to
ATT and the ATT Subgroup pursuant to this Article 3 for any Consolidated Return
Year or Combined Return Year.

            3.2       Federal Income Taxes for the Consolidated Period. B/E
Aerospace, on behalf of itself and other members of the B/E Aerospace Subgroup,
and ATT, on behalf of itself and other members of the ATT Subgroup, agree to
determine and allocate the federal income tax liability of the Affiliated Group
for any Consolidated Group Return Year among themselves in the following manner:

            (a) For each Consolidated Return Year, the ATT Subgroup shall be
allocated, and ATT shall pay to B/E Aerospace as provided in this Article 3 and
in Article 4 an amount equal to the federal income tax liability, if any
(including any alternative minimum Tax), of ATT and/or the other member(s) of
the ATT Subgroup included in the Consolidated Group Return, as determined by B/E
Aerospace in accordance with the methods set forth in this Section 3.2. Such
federal income tax liability shall equal the hypothetical tax liability of the
ATT Subgroup, computed as if the ATT Subgroup had filed a separate consolidated
federal income tax Return and not been included in the Consolidated Group
Return. If the ATT Subgroup's federal tax liability as so determined is zero or
less, then ATT shall not be entitled to any current payment from B/E Aerospace.

            (b) The ATT Subgroup's federal income tax liability for the Taxable
year during which ATT ceases to be a member of the Affiliated Group shall be
determined in accordance with the provisions of Regulations Section
1.1502-76(b)(2) by closing the books of ATT and the other members of the ATT
Subgroup as of the end of the last day of the Consolidated Return Year and
taking into account only items accruing during the portion of the Taxable year
ending on such date in computing such liability. Items shall not be pro-rated in
accordance with clauses (ii) or (iii) of Section 1.1502-76(b)(2) of the
Regulations except to the extent B/E Aerospace in its discretion determines that
it is imprac ticable to allocate particular items in accordance with the
preceding sentence.

                                       6
<PAGE>   7

            (c) The parties acknowledge that the allocation of federal income
tax liability provided for by this Section 3.2 is for purposes of determining
the parties' actual payment obligations to each other with respect to Taxes of
the Affiliated Group for the Consolidated Return Year and not for purposes of
computing earnings and profits pursuant to Section 1552 of the Code. B/E
Aerospace and ATT each recognizes that such allocation may differ from the
allocation provided by Section 1552 for earnings and profits purposes.

            (d) It is acknowledged that allocation of the consolidated federal
income tax liability for the Affiliated Group under Section 1.1552-1(a) of the
Regulations shall (in accordance with Section 1.1552-1(b)(2) of the
Regulations), in the amount allocated to each member of the B/E Aerospace
Subgroup and the ATT Subgroup, decrease the earnings and profits of such member
and be treated as a liability of such member for such amount. It is further
acknowledged that if allocations of federal income tax liability in accordance
with Section 3.2 of this Agreement differ from the allocations in accordance
with Section 1.1552-1(a)(1), B/E Aerospace and ATT hereby agree that such
differences will not create liabilities and receivables, but rather will be
regarded as distributions with respect to stock, contributions to capital, or
combinations thereof, as applicable.

            3.3       State, Local and Foreign Income and Franchise Taxes for
the Combined Period.

            (a) For each Combined Return Year, the ATT Subgroup shall be
allocated, and ATT shall pay to B/E Aerospace in accordance with this Article 3
and Article 4 an amount equal to the state, local and foreign income Tax
liability of ATT and/or such other ATT Subgroup members that are so included, as
determined under this Section 3.3. Such state, local or foreign income Tax
liability shall equal the hypothetical state, local or foreign income tax
liability of the ATT Subgroup members so included, computed as if they filed a
separate combined Return (or if only one such member is so included, a separate
state, local or foreign income or franchise Tax return) and not been included in
the Combined Return filed by the Combined Group. If the ATT Subgroup's state,
local or foreign income tax liability as so determined is zero or less, then ATT
shall not be entitled to any current payment from B/E Aerospace.

            (b) ATT shall be responsible for payment of any state, local or
foreign taxes due from it or any members of the ATT Subgroup, and B/E Aerospace
shall be responsible for payment of any state, local or foreign Taxes due from
B/E Aerospace or any member of the B/E Aerospace Subgroup, in connection with
state, local or foreign income or franchise Returns that are not Combined
Returns. ATT shall be responsible for preparing and filing any state, local or
foreign Tax returns, other than Combined Returns, for itself and the ATT
Subgroup.

            (c) The ATT Subgroup's applicable state, local or foreign Tax
liability for the Taxable year during which ATT ceases to be included in the
applicable Combined Return, absent any required rule to the contrary, shall be
determined in accordance with principles similar to the provisions of
Regulations Section 1.1502-76(b)(2) by closing the books of ATT and the other
members of the ATT Subgroup as of the end of the last day of the Combined Return
Year and taking into account only items accruing during the portion of the
Taxable year ending on such date in computing such liability.

                                       7
<PAGE>   8

            3.4       Computational Rules. For purposes of determining and
allocating Tax liabilities and payment obligations for the Consolidated Period
and the Combined Period, the ATT Subgroup's federal, state, local and foreign
income Tax liability will be computed by B/E Aerospace in a manner consistent
with B/E Aerospace's policies and procedures for accounting for income taxes for
financial statement purposes. In making such allocation, ATT shall not receive
any benefits from being a member of the Affiliated Group or Combined Group, such
as any benefit of the graduated Tax rates (including the rates provided under
Section 11 of the Code). In the case of any tax benefit where the amount of the
overall benefit to the Affiliated Group or Combined Group is limited, such as
any alternative minimum Tax exemption amount under Section 55 of the Code, the
benefit shall be allocated solely to the B/E Aerospace Subgroup.

            3.5       Time of Payment. To the extent that B/E Aerospace pays
any Tax on behalf of any member of the ATT Subgroup, ATT shall reimburse B/E
Aerospace within ten (10) days of receipt of an invoice requesting payment
thereof.

4. ESTIMATED PAYMENTS OF TAX SHARING LIABILITY

            4.1       Hypothetical Tax Computation and Payment Thereof. At
least three (3) days prior to each Estimated Payment Date of each Consolidated
Return Year and Combined Return Year, B/E Aerospace shall deliver to ATT
hypothetical computations of estimated Tax for the ATT Subgroup reflecting the
amounts, if any, of the estimated payment of federal, state, local and/or
foreign income taxes for such Consolidated Return Year or Combined Return Year,
as applicable, which the ATT Subgroup would have been required to pay on such
Estimated Payment Date if it were not included in the Affiliated Group or
Combined Group (calculated in accordance with Article 3). ATT shall pay to B/E
Aerospace, on such Estimated Payment Date, the amounts reflected as owing in
such hypothetical computations.

            4.2       Extension Payments. Notwithstanding Section 4.1, if B/E
Aerospace shall request an extension of time to file the Consolidated Group
Return and/or the Combined Return for any Consolidated Return Year or Combined
Return Year, B/E Aerospace shall compute the hypothetical amounts of the
federal, state, local and foreign Tax payments, as applicable, which would have
been payable by ATT on such Extension Payment Date had ATT requested such an
extension and had ATT not been included in the Affiliated Group or Combined
Group during such Consolidated Return Year or Combined Return Year (calculated
in accordance with Article 3). ATT shall pay to B/E Aerospace, on such Extension
Payment Date, the amounts computed by B/E Aerospace.

            4.3       Waiver. B/E Aerospace, in its sole discretion, may waive
on an annual basis the requirement for ATT to make the estimated Tax payments as
described in this Section 4.

            4.4       Date Consolidated Group and/or Combined Return Filed.
B/E Aerospace shall compute the hypothetical amount of the federal, state, local
and/or foreign Tax which would have been payable by the ATT Subgroup on such
actual filing date had the ATT Subgroup not been included in the Affiliated
Group or Combined Group during such Consolidated Return Year or Combined Return
Year (calculated in accordance with Section 3). ATT shall pay to B/E

                                       8
<PAGE>   9

Aerospace the amount computed, less the aggregate of any amounts previously paid
on each Estimated Payment Date and Extension Payment Date pursuant to this
Section 4. ATT shall pay B/E Aerospace the computed amount owed within ten (10)
days of the later of (i) the date on which the Tax Return is filed, or (ii)
receipt of an invoice showing the computed amount owed. If the aggregate amounts
paid by ATT on the Estimated Payment Dates and Extension Payment Dates for a
Consolidated Return Year or Combined Return Year exceed the computed
hypothetical federal, state, local and/or foreign income or franchise Tax
payable by ATT, then B/E Aerospace shall refund to ATT any such excess amount
within ten (10) days of filing the applicable Tax Return.

5.  DISPUTES WITH TAXING AUTHORITIES

            5.1       Confirmation of Authority. In the event of a Tax Contest
with the IRS or any other Taxing Authority concerning the amount of any Tax
liability of or refund due to the Affiliated Group or any member thereof for any
Consolidated Return Year or to the Combined Group or any member thereof for any
Combined Return Year, and in connection with every Group Refund Claim or other
claim for refund of Tax for any Consolidated Return Year or Combined Return
Year, ATT hereby expressly confirms, with respect to federal income tax
liability, the authority granted to B/E Aerospace in Regulations Section
1.1502-77 (and in any successor provision thereto) to act on behalf of ATT and
the ATT Subgroup notwithstanding that ATT may be liable for additional tax or
for additional payments to B/E Aerospace. With respect to such federal income
taxes and all other Taxes, ATT hereby expressly and irrevocably appoints B/E
Aerospace to be its sole agent and expressly relinquishes any rights it may have
to act for or represent itself in any manner in any such Tax Contest or with
respect to any such Group Refund Claim related to the time period in which ATT
and/or any member of the ATT Subgroup is a member of the Affiliated Group. ATT
hereby authorizes B/E Aerospace and its representatives to pursue such Tax
Contest, Group Refund Claim, or other claim for refund of Tax either
administratively or by court action. ATT hereby irrevocably agrees that B/E
Aerospace shall have the exclusive right, on behalf of ATT and the ATT Subgroup,
to make any and all decisions to pursue, settle, or appeal any Tax Contest,
Group Refund Claim or other claim for refund of Tax, and to control all
administrative and court proceedings and any and all negotiations and
settlements related thereto. ATT hereby expressly consents to B/E Aerospace
entering into settlements on its behalf and on behalf of the ATT Subgroup, as
B/E Aerospace deems appropriate in its sole discretion, exercised in good faith;
provided, however, that prior to settling an issue that would give rise to Tax
Adjustment for which ATT or a member of the ATT Subgroup would be liable under
this Agreement, ATT shall have the right and opportunity to review such
settlement. B/E Aerospace may, in its sole and absolute discretion accept or
reject any suggestions made by ATT with respect to such settlement. ATT may
assist in the defense of audit issues arising from its operations, at its own
expense, subject to the direction and control of B/E Aerospace. ATT shall
reimburse B/E Aerospace for all reasonable out-of pocket expenses (including,
with limitation, legal, consulting and accounting fees) in the course of a Tax
Contest regarding an item of the ATT Subgroup for any Taxable period during
which the ATT Subgroup was a member of the Affiliated Group or Combined Group to
the extent such expenses are reasonably attributable to such Tax Contest.

            5.2       Agreement to Cooperate. ATT agrees to cooperate and cause
the ATT Subgroup to cooperate fully and in a timely manner with B/E Aerospace in
connection with the

                                       9
<PAGE>   10

preparation of Tax Returns, the pursuit of any Group Refund Claim or other claim
for refund of Taxes or the conduct of any Tax Contest for any Consolidated
Return Year or Combined Return Year, at ATT's own expense by taking any and all
action that may be necessary or helpful, as requested by B/E Aerospace,
including (without limitation) furnishing to B/E Aerospace access to and copies
of all records and documents and making personnel available for interviews and
testimony. This agreement to cooperate extends beyond the date after which ATT
is no longer a member of the Affiliated Group or the Combined Group.

            5.3       Adjustments.

            (a) In the event there is an Adjustment, made pursuant to a Final
Determination, of an item of income, gain, loss, deduction, or credit with
respect to any Return of any member of the Affiliated Group or the Combined
Group for any Taxable period during which ATT and/or any other member of the ATT
Subgroup is or was a member of the Affiliated Group or the Combined Group:

            (i)   ATT shall be liable for, and shall indemnify and hold
        harmless, as appropriate, any member of the B/E Aerospace Subgroup, on
        an After Tax Basis against any and all ATT Tax Adjustments;

            (ii)  ATT shall be entitled to receive on an After Tax Basis the
        amount of any ATT Tax Benefits;

            (iii) B/E Aerospace shall be liable for, and shall indemnify and
        hold harmless, as appropriate, any member of the ATT Subgroup on an
        After Tax Basis against any and all B/E Aerospace Tax Adjustments; and

            (iv)  B/E Aerospace shall be entitled to receive on an After Tax
        Basis the amount of any B/E Aerospace Tax Benefits.

            (b) B/E Aerospace and ATT shall share the amount of any Tax
Adjustment if, and to the extent, each party is liable for and/or has an
obligation to make, or has the right to receive, as the case may be, any
indemnity payment, or other payment with respect to such Tax Adjustment under
Section 5.3(a), in proportion to the amounts of the underlying Adjustments
giving rise to such Tax Adjustment attributable to the B/E Aerospace Subgroup
and the ATT Subgroup respectively.

            (c) Indemnity payments required by Section 5.3(a) and 5.3(b) shall
be paid within 60 days of the date of such Final Determination. B/E Aerospace
shall provide ATT with prompt written notice of each such Final Determination.

6.  TAX ATTRIBUTE CARRYOVERS

            6.1       Carryforward Tax Attributes. The Carryforward Tax
Attributes available to ATT for Separate Return Periods will be determined by
allocating the Carryforward Tax Attributes of the B/E Aerospace Group to tax
periods beginning after the Separation Date among the B/E Aerospace Subgroup and
ATT Subgroup as described below:

                                       10
<PAGE>   11

            (a) Federal Tax Attributes. Any federal Carryforward Tax Attributes
allocable to ATT or a member of the ATT Subgroup under Regulations Section
1.502-21 and Proposed Regulations Section 1.41-8 shall remain with ATT or such
member. The portion, if any, of any B/E Aerospace Group consolidated unused
foreign tax credit which is allocable to ATT shall be determined separately with
respect to each of the items of income listed in Section 904(d) of the Code.

            (b) State, Local or Foreign Tax Attributes. State, local or foreign
Carryforward Tax Attributes shall not be allocated to ATT or any member of the
ATT Subgroup, unless under the provisions of applicable state, local or foreign
law or regulations such Carryforward Tax Attributes are expressly required to be
allocated to ATT or any member of the ATT Subgroup.

            6.2       Carryback Items from Separate Return Tax Periods. With
respect to carrybacks of ATT or net operating losses, net capital losses, unused
tax credits and other deductible or creditable Tax attributes to a Consolidated
Period or Combined Period from a Separate Return Period which would be permitted
under the Code and the Regulations (or comparable state, local or foreign law or
regulations), ATT shall make an irrevocable election under Regulations Section
1.1502-21(b)(3)(i) (or comparable state, local or foreign law or regulations),
to relinquish any carryback period which would include the Consolidated Period.
In cases where ATT cannot relinquish the carryback period or, if the parties
otherwise agree, B/E Aerospace shall cooperate with ATT in seeking Tax refunds
from the appropriate Taxing Authority, at ATT's expense, and ATT shall be
entitled to such refund, including interest paid by the Taxing Authority in
connection with such refund; provided however, that ATT shall indemnify and hold
B/E Aerospace harmless from and against any and all collateral Tax consequences,
including interest, resulting from or caused by the carryback of deductible or
creditable Tax attributes by ATT from a Separate Return Period to a Consolidated
Period, including but not limited to, Tax attributes of B/E Aerospace that
expire unused (including Tax attributes that expire during a Tax period
subsequent to the Tax period during which the ATT Tax attribute carried back was
generated) and which would have been used but for ATT's carryback. The amount of
such indemnity shall be limited to the actual Tax benefits to which B/E
Aerospace would have been entitled in the absence of the carryback of the
deductible or creditable Tax attribute of ATT. ATT shall have the right to
review the collateral Tax consequences being indemnified. The amount of the
refund due to ATT from B/E Aerospace shall be reduced and offset by the amount
of the indemnification, if any.

7.  PRIORITY OF AGREEMENT

            7.1       Fixing of Liability. The provisions of this Agreement
shall determine and fix the liability of the parties to each other as to the
matters provided for herein, regardless of how the payments made pursuant hereto
are treated for Tax purposes.

8.  OTHER GROUP MEMBERS

            8.1       Agreements. B/E Aerospace and ATT recognize that other
corporations are now or may from time to time hereafter become members of the
Affiliated Group or the Combined Group and it may become appropriate to adopt
different or additional methods of sharing Taxes. ATT, on behalf of itself and
the ATT Subgroup, hereby authorizes B/E

                                       11
<PAGE>   12

Aerospace to enter into the same, similar or different supplemental, conflicting
or replacement Tax sharing agreements on behalf of the Affiliated Group or the
Combined Group (including ATT and the ATT Subgroup), as the case may be with any
corporation which is now or may hereafter become a member of the Affiliated
Group or the Combined Group, as the case may be.

9.  RECORDS

            9.1       Retention by B/E Aerospace. B/E Aerospace shall, until
the end of the applicable statute of limitations for each Tax year (giving
effect to any extensions thereof), retain all material records, including but
not limited to, returns, supporting schedules, workpapers, correspondence, and
other documents relating to the Consolidated Group Returns and Combined Returns
filed for a Taxable year during which ATT is a member of the Affiliated Group
and/or the Combined Group and shall make such items available to ATT for
inspection or copying (at ATT's expense) during B/E Aerospace's regular business
hours.

            9.2       Retention by ATT. ATT shall, until the end of the
applicable statute of limitations for each Tax year (giving effect to any
extensions thereof), retain all material records, including but not limited to
supporting schedules, workpapers, correspondence, and other documents relating
to Consolidated Group Returns and Combined Returns filed for a Taxable year
during which ATT is a member of the Affiliated Group and/or the Combined Group
and shall make such items available to B/E Aerospace for inspection or copying
(at B/E Aerospace's expense) during ATT's regular business hours.

10. MISCELLANEOUS

            10.1      Governing Law. The internal laws of the State of New York
(irrespective of its choice of law principles) will govern the validity of this
Agreement, the construction of its terms and the interpretation and enforcement
of the rights and duties of the parties hereto.

            10.2      Assignment; Binding Upon Successors and Assigns. ATT may
not assign, whether voluntarily or by operation of law, any of its rights or
obligations hereunder without the prior written consent of B/E Aerospace, which
consent may be withheld in its sole discretion. B/E Aerospace may assign its
rights (but not its obligations) under this Agreement without the consent of
ATT; provided, however, that the rights and obligations of B/E Aerospace may be
assigned, without the consent of ATT, pursuant to a merger, exchange,
recapitalization or other reorganization to which B/E Aerospace is a party or by
operation of law. This Agreement will be binding upon and inure to the benefit
of the parties hereto and their respective successors and permitted assigns. Any
member corporation which leaves the Affiliated Group and/or the Combined Group
shall be bound by this Agreement.

            10.3      Severability. If any provision of this Agreement, or the
application thereof, will for any reason and to any extent be invalid or
unenforceable, the remainder of this Agreement and 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 greatest extent possible, the economic,
business, Tax and other purposes of the void or unenforceable provision.

                                       12
<PAGE>   13

            10.4      Counterparts. This Agreement may be executed in any
number of counterparts, each of which will be an original as regards any party
whose signature appears thereon and all of which together will constitute one
and the same instrument. This Agreement will become binding when one or more
counterparts hereof, individually or taken together, will bear the signatures of
all the parties reflected hereon as signatories.

            10.5      Other Remedies. Except as otherwise provided herein, 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
on such party, and the exercise of any one remedy will not preclude the exercise
of any other.

            10.6      Amendment and Waivers. Any term or provision of this
Agreement may be amended, and the observance of any term of this Agreement may
be waived (either generally or in a particular instance and either retroactively
or prospectively) only by a writing signed by the party to be bound thereby. The
waiver by a party of any breach hereof or default in the performance hereof will
not be deemed to constitute a waiver of any other default or any succeeding
breach or default. Failure by either party, at any time, to require performance
by the other party or to claim a breach of any provision of this Agreement shall
not be construed as a waiver of any right accruing under this Agreement, nor
shall it affect any subsequent breach or the effectiveness of this Agreement or
any part hereof, or prejudice either party with respect to any subsequent
action.

            10.7      Expenses. Unless otherwise provided, all fees and expenses
incurred in connection with this Agreement will be paid by the party incurring
such fees or expenses.

            10.8      Attorneys' Fees. Should suit be brought to enforce or
interpret any part of this Agreement, the prevailing party will be entitled to
recover, as an element of the costs of suit and not as damages, reasonable
attorneys' fees to be fixed by the court (including, without limitation, costs,
expenses and fees on any appeal). The prevailing party will be entitled to
recover its costs of suit, regardless of whether such suit proceeds to final
judgment.

            10.9      Dispute Resolution. The parties shall attempt in good
faith to resolve any dispute arising out of or relating to this Agreement and
shall attempt in good faith to negotiate a settlement of any dispute pursuant to
the following process:

            (a) Any party having a dispute or claim shall give the other party
written notice stating the nature of the dispute in reasonable detail. Within
ten (10) business days after delivery of the notice, the receiving party shall
submit to the other a written response also in reasonable detail. Within five
(5) business days after delivery of the written response the Chief Financial
Officer (or other individual who has authority to settle the controversy and who
has direct responsibility for administration of the relationships established
pursuant to this Agreement) for each party shall meet (in person or by
telephone) at a mutually acceptable time and place (including telephonic
conference), and thereafter as often as they reasonably deem necessary, to
attempt to resolve the dispute. All reasonable requests for information made by
one party to the other shall be honored.

                                       13
<PAGE>   14

            (b) If such matter has not been resolved within ten (10) business
days of the referral of the dispute to the Chief Financial Officers, then the
parties may pursue litigation or, if mutually agreed, alternative dispute
resolution mechanisms.

            10.10     Notices. All notices and other communications pursuant to
this Agreement shall be in writing and deemed to be sufficient if contained in a
written instrument and shall be deemed given if delivered personally,
telecopied, sent by nationally-recognized overnight courier or mailed by
registered or certified mail (return receipt requested), postage prepaid, to the
parties at the addresses indicated on the signature page of this Agreement (or
at such other address for a party as shall be specified by like notice). All
such notices and other communications shall be deemed to have been received (a)
in the case of personal delivery, on the date of such delivery, (b) in the case
of a telecopy, when the party receiving such copy shall have confirmed receipt
of the communication, (c) in the case of delivery by nationally-recognized
overnight courier, on the business day following dispatch, and (d) in the case
of mailing, on the tenth business day following such mailing. Failure of a party
to provide notice in a prescribed time period or in a timely manner shall not
constitute a waiver of the other party's obligation hereunder. Where notice is a
condition to payment, the obligation to make the payment shall not be waived,
forgiven or eliminated by virtue of a failure to give notice; however, the time
period in which an amount must be paid shall be measured from the date on which
notice is actually given.

            10.11     Construction of Agreement. A reference to a Section will
mean a Section in this Agreement unless otherwise explicitly set forth. The
titles and headings herein are for reference purposes only and will not in any
manner limit the construction of this Agreement which will be considered as a
whole.

            10.12     Jurisdiction and Venue. The parties hereto irrevocably
consent to and agree that any litigation or other dispute resolution proceeding
among the parties relating to this Agreement will take place in Palm Beach
County, Florida. The parties hereby irrevocably consent to the personal
jurisdiction of and the venue in the state and federal court within such county.

            10.13     Further Assurances. Each party agrees to cooperate fully
with the other parties and to execute such further instruments, documents and
agreements and to give such further written assurances as may be reasonably
requested by any other party to evidence and reflect the transactions
contemplated hereby and to carry into effect the intents and purposes of this
Agreement.

            10.14     Entire Agreement. This Agreement constitutes the entire
understanding and agreement of the parties hereto with respect to the subject
matter hereof and supersedes all prior and contemporaneous agreements or
understandings, inducements or conditions, express or implied, written or oral,
between the parties with respect hereto.

                       ADVANCED THERMAL TECHNOLOGIES, INC.
                                STOCK OPTION PLAN
                          (AS ADOPTED ON JULY 14, 2000)

1.     PURPOSE

       The purpose of this Stock Option Plan (the "PLAN") is to advance the
interests of Advanced Thermal Technologies, Inc. (the "COMPANY") by enhancing
the ability of the Company and its subsidiaries to attract and retain directors,
employees, consultants or advisers who are in a position to make significant
contributions to the success of the Company, to reward them for their
contributions and to encourage them to take into account the long-term interests
of the Company through ownership of shares of the Company's common stock (the
STOCK").

       The Plan provides for the award of options to purchase shares of the
Company's Stock. Options granted pursuant to the Plan may be incentive stock
options as defined in section 422 of the Internal Revenue Code of 1986 (as from
time to time amended, the "CODE") (any option that is intended to qualify as an
incentive stock option being referred to herein as an "INCENTIVE OPTION"), or
options that are not incentive options, or both. Options granted pursuant to the
Plan shall be presumed to be non-incentive options unless expressly designated
as incentive options.

2.     ELIGIBILITY FOR AWARDS

       Persons eligible to receive options under the Plan shall be all executive
officers of the Company and its subsidiaries and other employees, consultants
and advisers who, in the opinion of the Board, are in a position to make a
significant contribution to the success of the Company and its subsidiaries.
Incentive options shall be granted only to "employees" as defined in the
provisions of the Code or regulations thereunder applicable to incentive stock
options. A "SUBSIDIARY" for purposes of the Plan shall be a corporation in which
the Company owns, directly or indirectly, stock possessing 50% or more of the
total combined voting power of all classes of stock. Persons selected for awards
under the Plan are referred to herein as "PARTICIPANTS."

       Receipt of options under the Plan or awards under any other employee
benefit plan of the Company or any of its subsidiaries shall not preclude an
employee from receiving options or additional options under the Plan.

<PAGE>   2

3.     ADMINISTRATION

       The Plan shall be administered by the Board of Directors (the "BOARD") of
the Company. The Board shall have authority, not inconsistent with the express
provisions of the Plan, (a) to grant options to such participants as the Board
may select; (b) to determine the time or times when options shall be granted and
the number of shares of Stock subject to each option; (c) to determine which
options are, and which options are not, incentive options; (d) to determine the
terms and conditions of each option; (e) to prescribe the form or forms of any
instruments evidencing options and any other instruments required under the Plan
and to change such forms from time to time; (f) to adopt, amend and rescind
rules and regulations for the administration of the Plan; and (g) to interpret
the Plan and to decide any questions and settle all controversies and disputes
that may arise in connection with the Plan. Such determinations of the Board
shall be conclusive and shall bind all parties. Subject to Section 8 the Board
shall also have the authority, both generally and in particular instances, to
waive compliance by a participant with any obligation to be performed by the
participant under an option, to waive any condition or provision of an option,
and to amend or cancel any option (and if an option is canceled, to grant a new
option on such terms as the Board shall specify) except that the Board may not
take any action with respect to an outstanding option that would adversely
affect the rights of the participant under such option without such
participant's consent. Nothing in the preceding sentence shall be construed as
limiting the power of the Board to make adjustments required by Section 5(c) and
Section 6(j).

       The Board may, in its discretion, delegate some or all of its powers with
respect to the Plan to a committee (the "COMMITTEE"), in which event all
references in this Plan (as appropriate) to the Board shall be deemed to refer
to the Committee. The Committee, if one is appointed, shall consist of at least
two directors. A majority of the members of the Committee shall constitute a
quorum, and all determinations of the Committee shall be made by a majority of
its members. Any determination of the Committee under the Plan may be made
without notice or meeting of the Committee by a writing signed by a majority of
the Committee members. On and after registration of the Stock under the
Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), the Board
shall delegate the power to select directors and executive officers to receive
awards under the Plan and the timing, pricing and amount of such awards to a
committee or committees, the number of which shall satisfy the requirements of
rule 16b-3 ("RULE 16b-3") under the Exchange Act applicable to the Company and
all members of which shall be non-employee directors within the meaning of the
applicable provisions of Rule 16b-3 and, with respect to executive officers
only, "OUTSIDE DIRECTORS" within the meaning of Section 162(m) under the Code.

4.     EFFECTIVE DATE AND TERM OF PLAN

       The Plan shall become effective on July 14, 2000, the date that the Plan
was adopted by the Board and approved by the shareholders of the Company (the
"EFFECTIVE DATE"). No options shall be granted under the Plan after the
completion of ten years from that date, but options previously granted may
extend beyond that date.

<PAGE>   3

5.     SHARES SUBJECT TO THE PLAN

       (a)    Number of Shares. Subject to adjustment as provided in Section
5(c), the aggregate number of shares of Stock that may be delivered upon the
exercise of options granted under the Plan shall be 1,700,000. If any option
granted under the Plan terminates without having been exercised in full, or upon
exercise is satisfied other than by delivery of Stock, the number of shares of
Stock as to which such option was not exercised shall be available for future
grants within the limits set forth in this Section 5(a).

       The maximum number of shares for which options may be granted to any
individual over the life of the Plan shall be 850,000. The per-individual
limitations described in this paragraph shall be construed and applied
consistent with the rules and regulations under Section 162(m) of the Code.

       (b)    Shares to be Delivered. Shares delivered under the Plan shall be
authorized but unissued Stock or, if the Board so decides in its sole
discretion, previously issued Stock acquired by the Company and held in its
treasury. No fractional shares of Stock shall be delivered under the Plan.

       (c)    Changes in Stock. In the event of a stock dividend, stock split or
combination of shares, recapitalization or other change in the Company's capital
stock, the number and kind of shares of Stock subject to options then
outstanding or subsequently granted under the Plan, the exercise price of such
options, the maximum number of shares of Stock that may be delivered under the
Plan, and other relevant provisions shall be appropriately adjusted by the
Board, whose determination shall be binding on all persons.

       The Board may also adjust the number of shares subject to outstanding
options and the exercise price and the terms of outstanding options to take into
consideration material changes in accounting practices or principles,
extraordinary dividends, consolidations or mergers (except those described in
Section 6(j)), acquisitions or dispositions of stock or property or any other
event if it is determined by the Board that such adjustment is appropriate to
avoid distortion in the operation of the Plan, provided that no such adjustment
shall be made in the case of an incentive option, without the consent of the
participant, if it would constitute a modification, extension or renewal of the
option within the meaning of section 424(h) of the Code.

6.     TERMS AND CONDITIONS OF OPTIONS

       (a)    Exercise Price. The exercise price of each option shall be
determined by the Board but in the case of an incentive option shall not be less
than 100% (110%, in the case of an incentive option granted to a ten-percent
shareholder) of the fair market value of the Stock at the time the option is
granted; nor shall the exercise price be less, in the case of an original issue
of authorized stock, than par value. For this purpose, "FAIR MARKET VALUE" in
the case of

                                    3 of 10
<PAGE>   4

incentive options shall have the same meaning as it does in the provisions of
the Code and the regulations thereunder applicable to incentive options; and
"TEN-PERCENT SHAREHOLDER" shall mean any participant who at the time of grant
owns directly, or by reason of the attribution rules set forth in section 424(d)
of the Code, is deemed to own stock possessing more than 10% of the total
combined voting power of all classes of stock of the Company or of any of its
parent or subsidiary corporations.

       (b)    Duration. Options shall be exercisable during such period or
periods as the Board may specify. The latest date on which an option may be
exercised (the "FINAL EXERCISE DATE") shall be the date that is ten years (five
years, in the case of an incentive option granted to a "ten-percent shareholder"
as defined in (a) above) from the date the option was granted or such earlier
date as the Board may specify at the time the option is granted.

       (c)    Exercise of Options.

       (1)    Unless the Board at the time of grant otherwise specifies in the
              case of a particular option or options, each option shall first
              become exercisable as follows:

              Except as provided in Section 6(i) hereof, an option shall vest
              and become exercisable from and after the date of grant for 25% of
              the total number of shares subject to the option, and shall become
              exercisable for an additional 25% on each of the first, second and
              third anniversaries of the date of grant. If the number of shares
              for which the option is exercisable at any time in accordance with
              this paragraph includes a fractional share, the number of shares
              of which the option is then exercisable shall be rounded to the
              nearest whole share.

              In the case of an option not immediately exercisable in full, the
              Board may, at any time, accelerate the time at which all or any
              part of the option may be exercised.

       (2)    Options may be exercised only in writing. Written notice of
              exercise must be signed by the proper person and furnished to the
              Company, together with (i) such documents as the Board may require
              and (ii) payment in full as specified below in Section 6(d) for
              the number of shares for which the option is exercised.

       (3)    The delivery of Stock upon the exercise of an option shall be
              subject to compliance with (i) applicable federal and state laws
              and regulations, (ii) if the outstanding Stock is at the time
              listed on any stock exchange, the listing requirements of such
              exchange, and (iii) Company counsel's approval of all other legal
              matters in connection with the issuance and delivery of such
              Stock. If the sale of Stock has not been registered under the
              Securities Act of 1933, as amended, the Company may require, as a
              condition to exercise of the option, such representations or
              agreements as counsel for the Company may consider

                                    4 of 10
<PAGE>   5

              appropriate to avoid violation of such Act and may require that
              the certificates evidencing such Stock bear an appropriate legend
              restricting transfer.

       (4)    In the case of an option that is not an incentive option, the
              Board shall have the right to require that the participant
              exercising the option remit to the Company an amount sufficient to
              satisfy any federal, state, or local withholding tax requirements
              (or make other arrangements satisfactory to the Company with
              regard to such taxes) prior to the delivery of any Stock pursuant
              to the exercise of the option. If permitted by the Board, either
              at the time of the grant of the option or the time of exercise,
              the participant may elect, at such time and in such manner as the
              Board may prescribe, to satisfy such withholding obligation by (i)
              delivering to the Company Stock (which in the case of Stock
              acquired from the Company shall have been owned by the participant
              for at least six months prior to the delivery date) having a fair
              market value equal to such withholding obligation, or (ii)
              requesting that the Company withhold from the shares of Stock to
              be delivered upon the exercise a number of shares of Stock having
              a fair market value equal to such withholding obligation.

              In the case of an incentive option, if at the time the option is
              exercised the Board determines that under applicable law and
              regulations the Company could be liable for the withholding of any
              federal or state tax with respect to a disposition of the Stock
              received upon exercise, the Board may require as a condition of
              exercise that the participant exercising the option agree (i) to
              inform the Company promptly of any disposition (within the meaning
              of section 424(c) of the Code and the regulations thereunder) of
              Stock received upon exercise, and (ii) to give such security as
              the Board deems adequate to meet the potential liability of the
              Company for the withholding of tax, and to augment such security
              from time to time in any amount reasonably deemed necessary by the
              Board to preserve the adequacy of such security.

       (5)    If an option is exercised by the executor or administrator of a
              deceased participant, or by the person or persons to whom the
              option has been transferred by the participant's will or the
              applicable laws of descent and distribution, the Company shall be
              under no obligation to deliver Stock pursuant to such exercise
              until the Company is satisfied as to the authority of the person
              or persons exercising the option.

       (d)    Payment for and Delivery of Stock. Stock purchased upon exercise
of an option under the Plan shall be paid for as follows: (i) in cash or by
personal check, wire transfer, certified check, bank draft or money order
payable to the order of the Company or (ii) if so permitted by the Board (which,
in the case of an incentive option, shall specify such method of payment at the
time of grant), (A) through the delivery of shares of Stock (which, in the case
of Stock acquired from the Company, shall have been held for at least six
months) having a fair market value on the last business day preceding the date
of exercise equal to the purchase

                                    5 of 10
<PAGE>   6

price or (B) by having the Company hold back from the shares transferred upon
exercise Stock having a fair market value on the last business day preceding the
date of exercise equal to the purchase price (C) by delivery of an unconditional
and irrevocable undertaking by a broker to deliver promptly to the Company
sufficient funds to pay the exercise price or (D) by any combination of the
permissible forms of payment; provided, that if the Stock delivered upon
exercise of the option is an original issue of authorized Stock, at least so
much of the exercise price as represents the par value of such Stock shall be
paid other than with a personal check or promissory note of the participant.

       (e)    Rights as Shareholder. A participant shall not have the rights of
a shareholder with regard to awards under the Plan except as to Stock actually
received by the participant under the Plan upon exercise of a stock option.

       (f)    Nontransferability of Awards. Except as the Board may otherwise
determine, no award may be transferred other than by will or by the laws of
descent and distribution; provided, however, that the Board may, in its
discretion and subject to such terms and conditions as it shall specify, permit
the transfer of an option for no consideration to a Participant's family members
or to one or more trusts or partnerships established in whole or in part for the
benefit of one or more of such family members (collectively, "PERMITTED
TRANSFEREES"); and provided further that this sentence shall not preclude a
Participant from designating a beneficiary to receive the Participant's
outstanding options following the death of the Participant. Any option
transferred to a Permitted Transferee shall be further transferable only by will
or the laws of descent and distribution or, for no consideration, to another
Permitted Transferee of the Participant. During the lifetime of the Participant,
an option, shall be exercisable only by the Participant or by a Permitted
Transferee to whom such option has been transferred in accordance with this
Section 6(f).

       (g)    Death; Disability. If a participant dies or becomes disabled
during his or her employment with the Company, each option held by the
participant immediately prior to death or termination for disability may be
exercised, to the extent it was exercisable immediately prior to the
Participant's death or termination for disability, by the participant, or in the
event of the participant's death, the participant's executor or administrator or
by the person or persons to whom the option transferred by will or the
applicable laws of descent and distribution, at any time within the one-year
period (or such longer or shorter period as the Board may determine) beginning
with the date of the participant's death or termination for disability but in no
event beyond the Final Exercise Date. All options held by a participant
immediately prior to death or disability that are not then exercisable shall
terminate on the date of death or termination for disability.

       (h)    Termination of Service Other Than By Death or Disability. If an
employee's employment with the Company and its subsidiaries terminates for any
reason other than for death, disability or Cause, each option held by the
employee immediately prior

                                    6 of 10
<PAGE>   7

to such employment termination may be exercised, to the extent it was
exercisable immediately prior to the employment termination, at any time within
the three-month period commencing on the date of termination but in no event
beyond the Final Exercise Date. Notwithstanding the foregoing, if an employee's
employment with the Company and its subsidiaries terminates for any reason other
than death, disability or Cause, and such employee has been employed by the
Company for a period of ten years or more, each option held by the employee
immediately prior to such employment termination shall remain exercisable, to
the extent it was exercisable immediately prior to the employment termination,
until the Final Exercise Date; provided, however, that if the Board determines
in good faith that the employee has engaged in conduct that is harmful to the
Company either in the course of such employee's employment or subsequently or in
connection with the termination of employment, then each option held by the
employee shall terminate forthwith; and provided further that the Board may
provide in any employee's award that upon such employee's termination of
employment for any reason other than death, disability or Cause, regardless of
the number of years such employee has been employed, each option held by the
employee immediately prior to such employment termination may be exercised, to
the extent it was exercisable immediately prior to the employment termination,
at any time within the three-month period commencing on the date of termination
but in no event beyond the Final Exercise Date. All options held by a
participant immediately prior to the Participant's termination of service for
any reason other than death or disability that are not then exercisable shall
terminate on the Participant's date of termination. In the event that an
employee is terminated for Cause, each option held by the employee immediately
prior to such employment termination shall terminate forthwith. For purposes of
this Section 6(h), employment shall not be considered terminated (i) in the case
of sick leave or other bona fide leave of absence approved for purposes of the
Plan by the Board, so long as the employee's right to reemployment is guaranteed
either by statute or by contract, or (ii) in the case of a transfer of
employment between the Company and a subsidiary or between subsidiaries, or to
the employment of a corporation (or a parent or subsidiary corporation of such
corporation) issuing or assuming an option in a transaction to which section
424(a) of the Code applies.

       For purpose of the Plan, "CAUSE" shall mean (i) the participant's
material failure, refusal or neglect to perform and discharge his duties and
responsibilities; (ii) a breach of any fiduciary duties the participant has the
Company or any subsidiary or affiliate thereof; or (iii) a breach of any
protective covenant provision by the participant; or (iv) a felony conviction or
a conviction for any crime involving the participant's personal dishonesty or
moral turpitude.

       In the case of a participant who is not an employee, provisions relating
to the exercisability of options following termination of service shall be
specified in the award. If not so specified, all options held by such
participant that are not then exercisable shall terminate upon termination of
service. Options that are exercisable on the date the participant's service as a
director, consultant or adviser terminates shall continue to be exercisable for
a period of three months (or such longer period as the Board may determine, but
in no event beyond the Final Exercise Date) unless the director, consultant or
adviser was terminated for cause that in the opinion of the Board casts such
discredit on him or her as to justify termination of his or her options. After
completion of the post-termination exercise period, such options shall

                                    7 of 10
<PAGE>   8

terminate to the extent not previously exercised, expired or terminated.

       (i)    Change in Control. In the event of a "CHANGE IN CONTROL" all
outstanding options shall thereupon terminate, provided that at least 20 days
prior to the effective date of any Change in Control all outstanding options
shall accelerate and become exercisable immediately prior to consummation of the
Change in Control unless the Board shall have arranged, subject to consummation
of Change in Control, to have the surviving or acquiring corporation or an
affiliate of that corporation assume the options or grant to participants
replacement options, which options in the case of incentive options shall
satisfy, in the determination of the Board, the requirements of section 424(a)
of the Code.

       A "CHANGE IN CONTROL" shall be deemed to have occurred when:

              (A)    Any Person is or becomes the "beneficial owner" (as defined
                     in Rule 13d-3 of the Securities Exchange Act of 1934 (the
                     "EXCHANGE ACT"), whether or not the Company is then subject
                     to the terms of the Exchange Act), directly or indirectly,
                     of securities of the Company representing fifty (50%)
                     percent or more of the combined voting power of the
                     Company's then-outstanding securities; or

              (B)    The individuals who were directors on the Effective Date,
                     or any director whose appointment or election by the Board
                     or nomination for election by the Company's shareholders
                     was approved or recommended by a vote of at least
                     two-thirds (2/3) of the directors then in office, who
                     either were directors as of the Effective Date or whose
                     appointment, election or nomination for election was
                     previously so approved or recommended (other than a
                     director whose initial assumption of office is in
                     connection with an actual or threatened election contest,
                     including, but not limited to, a consent solicitation,
                     relating to the election of directors of the Company) cease
                     for any reason to constitute a majority of the directors
                     then serving on the Company's board of directors; or

              (C)    There is consummated a merger or consolidation of the
                     Company, other than (x) a merger or consolidation which
                     would result in the voting securities of the Company
                     outstanding immediately prior to such merger or
                     consolidation continuing to represent (either by remaining
                     outstanding or by being converted into voting securities of
                     the surviving entity or any parent thereof), in combination
                     with the ownership of any trustee or other fiduciary
                     holding securities under an employee benefit plan of the
                     Company or any subsidiary, at least fifty percent (50%) of
                     the combined voting power of the securities of the Company
                     or such surviving entity, or any parent thereof,
                     outstanding immediately after such merger or consolidation,
                     or (y) a merger or consolidation effected to implement a
                     recapitalization of the Company (or similar transaction) in
                     which no

                                    8 of 10
<PAGE>   9

                     Person is or becomes the beneficial owner, directly or
                     indirectly, of the Company's securities (excluding any
                     securities acquired directly from the Company or its
                     affiliates other than in connection with the acquisition by
                     the Company or its affiliates of a business) representing
                     twenty percent (20%) or more of the combined voting power
                     of the Company's then outstanding securities; or

              (D)    The shareholders of the Company approve a plan of complete
                     liquidation or dissolution of the Company or there is
                     consummated an agreement for the sale or disposition by the
                     Company of all or substantially all of the Company's
                     assets, other than a sale or disposition by the Company of
                     all or substantially all of the Company's assets to an
                     entity, at least fifty percent (50%) of the combined voting
                     power of the voting securities of which are owned by
                     shareholders of the Company in substantially the same
                     proportions as their ownership of the Company immediately
                     prior to such sale.

       For purposes of the above, "Person" shall mean any person, entity or
       "group" within the meaning of Section 13(d)(3) or Section 14(d)(2) of the
       Exchange Act, except that such term shall not include (i) the Company or
       any of its subsidiaries, (ii) a trustee or other fiduciary holding
       securities under an employee benefit plan of the Company or any of its
       subsidiaries, (iii) an underwriter temporarily holding securities
       pursuant to an offering of such securities, or (iv) a corporation owned,
       directly or indirectly, by the shareholders of the Company in
       substantially the same proportions as their ownership of stock of the
       Company;

provided, however, that the Board may amend this definition of Change in Control
with regards to particular option grants.

       (j)    Substitute Options. The Board may grant options under the Plan in
substitution for options held by directors, employees, consultants or advisers
of another corporation who concurrently become directors, employees, consultants
or advisers of the Company or a subsidiary of the Company as the result of a
merger or consolidation of that corporation with the Company or a subsidiary of
the Company, or as the result of the acquisition by the Company or a subsidiary
of the Company of property or stock of that corporation. The Company may direct
that substitute options be granted on such terms and conditions as the Board
considers appropriate in the circumstances.

7.     SERVICE RIGHTS

       Neither the adoption of the Plan nor the grant of awards shall confer
upon any participant any right to continue as an employee or director of, or
consultant or adviser to, the Company or any parent or subsidiary or affect in
any way the right of the Company or parent or subsidiary to terminate them at
any time. Except as specifically provided by the Board in

                                    9 of 10
<PAGE>   10

any particular case, the loss of existing or potential profit in options granted
under this Plan shall not constitute an element of damages in the event of
termination of the relationship of a participant even if the termination is in
violation of an obligation of the Company to the participant by contract or
otherwise.

8.     EFFECT, DISCONTINUANCE, AMENDMENT AND TERMINATION

       Neither adoption of the Plan nor the grant of options to a participant
shall affect the Company's right to grant options to such participant that are
not subject to the Plan, to issue to such participant Stock as a bonus or
otherwise, or to adopt other plans or arrangements under which Stock may be
issued.

       The Board may at any time discontinue granting options under the Plan.
The Board may at any time or times amend the Plan or any outstanding award for
the purpose of satisfying the requirements of section 422 of the Code or of any
changes in applicable laws or regulations or for any other purpose that may at
the time be permitted by law, or may at any time terminate the Plan as to any
further grants of options; provided, however, that (except to the extent
expressly required or permitted herein above) no such amendment shall, without
the approval of the shareholders of the Company if such shareholder approval is
required by then current law, (a) increase the maximum number of shares
available under the Plan, (b) change the group of participants eligible to
receive options under the Plan, (c) reduce the price at which incentive options
may be granted, (d) extend the time within which options may be granted, (e)
alter the Plan in such a way that incentive options already granted hereunder
would not be considered incentive stock options under section 422 of the Code,
or (f) amend the provisions of this Section 8; provided further that no such
amendment shall adversely affect the rights of any participant (without the
participant's consent) under any option previously granted.
