         Re:   IMSI Shareholders v. Wynn Westmoreland, et al.
               Civil No. 990908831 (Hon. Peuler)

Dear Peter:

         This binding letter agreement embodies the parties' understanding of
the core terms of a settlement intended to resolve certain claims in the current
litigation. These core terms are subject to a more detailed memorialization in a
formal Settlement Agreement which I intend to draft and present to you for your
review once this letter agreement has been signed by the parties. In addition,
as you know, this settlement is subject to Court approval. This letter agreement
shall be null and void if the Settlement Agreement is not approved by the Court
despite the parties' best efforts to obtain such approval.

         1. IMSI will ratify and issue to Eagle or, at Eagle's election, to
Great Wall New Buildings Systems, Inc. ("GWNBS"), Construction Technologies of
India, Inc. ("CT India"), and/or Construction Technologies of Mexico, Inc. ("CT
Mexico") the licenses for China, India, and Mexico, subject to the additional
terms set forth below. Prior to issuance of a license to GWNBS, CT India or CT
Mexico, any such entity must execute a license agreement containing, among other
things, an obligation to pay royalties in the amount and on the schedule set
forth in paragraph 4 below. Eagle represents and warrants that no remaining
Defendant (a) is an officer or director of GWNBS, CT India or CT Mexico, or (b)
directly or indirectly owns a controlling interest in GWNBS, CT India or CT
Mexico. Eagle further represents and warrants that it will not sell any
ownership interests in GWNBS, CT India or CT Mexico to such individuals and
entities until the conclusion of the current litigation as defined in paragraph
5 below. As set forth in the releases described in paragraph 14 below,
plaintiffs expressly waive any claim they may have to the ownership interest

----------------------------

Eagle now holds in GWNBS, CT India and CT Mexico and will not seek to recover
such ownership from Eagle for claims covered by that release. Eagle will pay
$25,000.00 for each of these three licenses into an escrow fund designated by
plaintiffs. This payment will be made by Eagle within three business days from
the date that the Settlement Agreement is executed by the parties. Plaintiffs
agree that they will not access the funds paid into the escrow fund under this
letter agreement and the Settlement Agreement until the Settlement Agreement is
approved by the Court, and that all funds withdrawn from the escrow fund will be
used by plaintiffs for IMSI-related expenses only. If the Settlement Agreement
is not approved by the Court despite the parties' best efforts, all funds in
escrow paid by Eagle shall be returned to Eagle. The parties agree to enter into
a mutually acceptable license agreement for each of these three licenses
containing language consistent with this letter agreement and the Settlement
Agreement, as well as other terms agreed upon by the parties.

         2. IMSI will ratify the existing license for Romania held by Advantage
Technologies. Eagle agrees to pay royalties on this license as set forth below.
The parties agree to enter into a mutually acceptable license agreement for this
license which contains language consistent with this letter agreement and the
Settlement Agreement, as well as other terms agreed upon by the parties.

         3. IMSI and Eagle will enter into a mutually acceptable license
agreement for a new license territory which contains language consistent with
this letter agreement and the Settlement Agreement, as well as other terms
agreed upon by the parties. This license is referred to herein as the
"Southeastern Europe" license. The geographic scope of this license will be the
countries of Turkey, Croatia, Bosnia, and Kosovo. The license fee for this
license will be $50,000.00. Eagle agrees to pay this amount into the escrow fund
described in paragraph 1 above within three business days from the date that the
Settlement Agreement is executed by the parties. Eagle agrees to obtain within
ten days of the execution of this letter agreement Mr. Wayne Johnson's release
of claims to the allegedly pre-existing "Balkans" license on behalf of Mr.
Johnson and any entity which he owns or controls or which claims ownership of
the pre-existing "Balkans" license, and to indemnify and defend IMSI against any
claims brought by Wayne Johnson or any entity owned or controlled by him against
IMSI relating to the pre-existing "Balkans" license.

         4. Eagle will pay to IMSI royalties of 4.5% of gross revenues generated
in any of its license territories. The license territories are as identified
herein. Gross revenues will be broadly defined as all revenues generated by
Eagle on the sale of any IMSI-related products, which shall by defined as any
product which incorporates the patents or other intellectual property of IMSI,
including but not limited to the IMSI Block system, the associated patents, the
associated trademarks, the surface coating system (also known as Q-Bond, the
ownership of which is at issue in the current litigation), and the inserts. As
to be set forth more specifically in the respective license agreement for each
of the five licenses described herein, Eagle agrees that it will not seek to
circumvent its royalty obligations by selling or otherwise transferring
IMSI-related products at less than fair market value. To the extent not paid in
the 4.5% royalty described herein, Eagle will pay minimum royalties as follows:

                           per month; and $7,500 per month from and including
                           October 2001 onward.

         Mexico:           July 2000 through December 2000, $2,000.00 per month;
                           January 2001 through June 2001, $2,500.00 per month;

                           and $7,500 per month from and including January 2002
                           onward.

These royalties will be paid into the escrow fund described in paragraph one
above. In the event that Eagle fails to pay the minimum royalty for any license
by the last day of the month in which it is due, IMSI agrees to provide written
notice of such default, and Eagle shall have thirty days after written notice to
cure the default. In the event that Eagle fails to cure its default, Eagle
agrees that it will forfeit that license and will be subject to collection
proceedings by IMSI. Eagle agrees to pay IMSI its reasonable attorneys' fees and
costs incurred in such collection proceedings and to pay interest on past-due
royalties in the amount of 10% per annum.

         5. Eagle agrees that, from the date of its signature on this letter
agreement, it will not engage in IMSI-related business, including sales,
marketing and all other aspects of IMSI-related business, directly or indirectly
through joint venture partners or existing IMSI licensees, in any location other
than the countries of China, India, Mexico, Romania, Turkey, Kosovo, Croatia,
and Bosnia, until the earliest of the following: (1) the conclusion of this
litigation (signified by entry of a final, non-appealable Order in the case
number set forth above); (2) January 1, 2002; or (3) written approval in advance
by IMSI's Board. Eagle further agrees that it will not engage in IMSI-related
business in any of the eight countries designated in this paragraph if the IMSI
license which covers each such country is not in good standing. Good standing
shall mean that the minimum royalties for the relevant license are current, and
all other obligations of the licensee under the license agreement are being
satisfactorily performed by the licensee. In the event that Eagle engages in
IMSI-related business in violation of this paragraph, Eagle agrees that IMSI is
entitled to injunctive relief and to its reasonable attorneys' fees and costs in
pursuing such injunctive relief.

----------------------------

         6. Eagle agrees that, until the conclusion of the current litigation
(as defined above), Eagle and its officers, directors, and agents will not
knowingly sell any IMSI shares or Eagle shares to Wynn Westmoreland, Richard
Anderson, or Michael Smith, to any entity which Wynn Westmoreland, Richard
Anderson, or Michael Smith owns or controls, directly, indirectly, or
beneficially, or to any relatives of Wynn Westmoreland, Michael Smith, or
Richard Anderson. The parties acknowledge that Eagle cannot stop these
individuals and entities from acquiring stock in the open market or through a
public offering. Eagle agrees, however, that, in addition to its other
obligations set forth in this paragraph, Eagle and its officers, directors, and
agents will not offer stock in any Eagle public offering to Wynn Westmoreland,
Richard Anderson, or Michael Smith, to any entity which Wynn Westmoreland,
Richard Anderson, or Michael Smith owns or controls, directly, indirectly, or
beneficially, or to any relatives of Wynn Westmoreland, Michael Smith, or
Richard Anderson on terms that are more favorable than any other member of the
public seeking to buy such shares through a public offering.

         7. The "lock-up" agreement which is attached hereto as Exhibit A is
incorporated as part of this letter agreement. Eagle agrees that it will not
alter or permit to be altered the terms of the lock-up agreement without the
prior written consent of Dr. Strobel and Mr. Hermanson. To the extent that
persons or entities related to or controlled by the remaining defendants
received Eagle shares or (b) interests in IMSI joint ventures or other
enterprises (including but not limited to GWNBS, CT India, and CT Mexico), and
that such persons have not signed the lock-up agreement, Eagle agrees not to
oppose any effort by plaintiffs to obtain a court order to lock up such shares.
The parties agree that unrestricted Eagle shares received through an exchange of
IMSI shares or shares in an IMSI-related joint venture or other enterprise for
which cash was paid at fair market value are not subject to the lock-up
requirement. In the event that plaintiffs provide verifiable evidence that fair
market value was not paid for any such shares, Eagle agrees not to oppose an
effort by plaintiffs to obtain a court order to lock up the equivalent Eagle
shares and, if IMSI shares are involved, Eagle agrees that such IMSI shares will
be returned to IMSI by Eagle. Eagle agrees to provide to plaintiffs all
information in its possession which may be relevant to the terms of this
paragraph.

         8. Eagle hereby assigns to IMSI whatever rights Eagle gained to the
IMSI Block System through its assignment agreement with Stan and Weldon Johnson.
Eagle further agrees and stipulates that it has no ownership interests in the
IMSI Block System or IMSI's other intellectual property and assets other than
whatever rights Eagle has as an IMSI licensee and shareholder.

         9. Eagle agrees not to seek reimbursement of funds it paid on behalf of
IMSI, including but not limited to funds paid to Stan and Weldon Johnson by
Eagle. Eagle will provide to plaintiffs within a reasonable time all documents
and other information sought by plaintiffs relating to funds paid by Eagle on
behalf of IMSI.

----------------------------

         10. Eagle (including its officers directors and authorized agents) will
not solicit, purchase or otherwise acquire any additional IMSI shares or right
to such shares until conclusion of the current litigation (as defined above).
Eagle represents that it will not authorize Michael Smith, Wynn Westmoreland, or
Richard Anderson (or entities controlled by or owned in whole or in part by any
of them) to solicit, purchase or otherwise acquire additional IMSI shares or
rights to such shares for, on behalf of, or for the benefit of Eagle or to take
any other actions on behalf of Eagle which would violate this letter agreement
or the Settlement Agreement. Based on that representation, plaintiffs
acknowledge that Wynn Westmoreland, Michael Smith, and Richard Anderson are not
future agents of Eagle for those purposes. Eagle is not admitting by this letter
agreement that any of these individuals have been or are agents of Eagle, and
subject to the release of Eagle described in paragraph 14 below plaintiffs are
not precluded from raising allegations in the current litigation that the
remaining defendants conspired with or otherwise involved Eagle for improper
purposes to the detriment of plaintiffs. Except for any IMSI shares Eagle may
have obtained from Joy and/or Cheryl Ray, Eagle further agrees that it will not
sell or transfer any of its currently held IMSI shares without the prior written
approval of Dr. Rudolf Strobel and Craig Hermanson until the conclusion of the
current litigation (as defined above). With respect to the shares Eagle may have
obtained from Joy and/or Cheryl Ray, plaintiffs will not preclude Eagle from
seeking to exchange any such shares for the Eagle shares Eagle may have
transferred to Joy and/or Cheryl Ray as part of any such share exchange. In the
event of such a transfer of IMSI shares from Eagle to Joy and/or Cheryl Ray,
Eagle shall provide to counsel for plaintiffs copies of all documents relating
to the exchange.

         11. If plaintiffs obtain a judgment against Smith, Westmoreland, and/or
Anderson concerning their conduct as officers or directors of IMSI, Eagle, at
the request of plaintiffs, will vote any IMSI shares it owns or controls to
remove such individual(s) as officers and directors.

         12. In the event that plaintiffs or IMSI obtain a judgment which holds
that any of the IMSI shares now held by Eagle were improperly issued or
retained, Eagle agrees to return those specified shares to IMSI without
compensation from IMSI. The parties agree that Eagle does not waive its right to
seek compensation from the person or persons who exchanged such IMSI shares for
Eagle shares. In the event there is a settlement by which one or more of the
defendants agree that any IMSI shares were improperly issued or retained by any
or all of them (or by entities owned or controlled by any or all of them), Eagle
will return those shares to IMSI upon the tender to Eagle of the corresponding
Eagle shares. With respect to ownership interests in GWNBS, CT India and CT
Mexico which Eagle obtained from the remaining defendants, plaintiffs will not
seek to recover such interests from Eagle for any claim subject to the release
described in paragraph 14 below. Plaintiffs are not precluded from seeking any
corresponding Eagle shares in satisfaction of a judgment against, or settlement
with, any of the remaining defendants.

----------------------------

         13. Eagle agrees that, until the conclusion of the litigation (as
defined above), Eagle will not vote any IMSI shares which it owns or controls
toward retaining or removing any existing member of IMSI's Board or toward
appointing any new IMSI Board member without the prior written approval of Craig
Hermanson and Dr. Rudolf Strobel. Eagle further agrees that during the pendency
of the current litigation, it will not vote any IMSI shares which it owns or
controls to terminate the current litigation or any aspect of it without the
prior written approval of Dr. Strobel and Mr. Hermanson. Plaintiffs agree that
they will not initiate a shareholding meeting for purposes of retaining,
removing or electing members to IMSI's Board without Eagle's consent for six
months from the date of this letter agreement. However, plaintiffs are not
precluded from removing at any time any IMSI Board member without Eagle's
consent through an order of a court of competent jurisdiction or through a
settlement or other agreement with any such IMSI Board member.

         14. The parties agree to execute mutual releases. Eagle will be
dismissed from the current litigation with prejudice. Eagle will drop its
counterclaims with prejudice. Plaintiffs and Eagle will each bear their own
respective attorneys' fees and costs.

         15. Despite being dismissed from the litigation, Eagle will produce any
otherwise discoverable documents without a subpoena, provided plaintiffs pay any
copying costs. Eagle also will produce witnesses under its control without a
subpoena, provided that plaintiffs pay any travel expenses or other out of
pocket costs, such expenses and costs to be reasonable and approved by
plaintiffs' counsel prior to being incurred. Eagle agrees to provide plaintiffs
with all documents, information, and witnesses relating to exchanges of IMSI
stock for Eagle stock, all transactions relating to any IMSI-related joint
venture, and all transactions with any other defendant in this matter. Eagle
also agrees that it will produce information and documents relating to all
communications with present or former IMSI shareholders. Eagle also will provide
plaintiffs with information and documents relating to all past, present, or
future funds that Eagle has paid, is paying, or is obligated to pay to Wynn
Westmoreland or any entity owned or controlled (in whole or in part) by
Westmoreland or any member of Westmoreland's family. Eagle will not seek
reimbursement for lost time or any associated legal fees in performing these
tasks, but plaintiffs agree to pay any reasonable out of pocket costs incurred
by Eagle in complying with plaintiffs' requests for documents or witnesses, such
costs to be approved by plaintiffs' counsel prior to being incurred by Eagle.

         16. Eagle agrees that in the event that a Court or the IMSI Board
determines that an IMSI license was issued or retained without adequate
consideration or without proper IMSI Board approval (excepting those licenses
which are included in this settlement), and that the license is therefore not in
good standing, then to the extent Eagle retains an equity interest in IMSI at
that time, Eagle will support the cancellation of each such license and
recoupment of outstanding royalty payments. Eagle also agrees that to the extent
it retains an equity interest in IMSI at that time, Eagle will support the
revocation of each license for which the licensee fails or has failed to pay
minimum royalties pursuant to that licensee's license agreement or which is
otherwise not in good standing.

----------------------------

         17. Eagle and the plaintiffs agree that they will take all steps
necessary for the settlement to be approved, including approval by the Court, by
IMSI's Board, and by IMSI's shareholders (if deemed necessary by the Court).

         18. The parties agree that in the event of a breach of this letter
agreement, the non- breaching party will be entitled to its reasonable
attorneys' fees and costs arising out of or in connection with such breach,
whether incurred with or without litigation, on appeal, or otherwise.

                                                     Sincerely,

                                                     Jonathan O. Hafen

                                   ARTICLE II

                                    The Plan

       2.1    Name. This plan shall be known as the "Intellon Corporation
Amended and Restated Incentive Plan."

                                      -2-
<PAGE>   3

       2.2    Purpose. The purpose of the Plan is to attract and retain persons
of ability as employees and consultants of the Company, motivate and reward good
performance, encourage such individuals to continue to exert their best efforts
on behalf of the Company and provide further opportunities for stock ownership
by such individuals in order to increase their proprietary interests in the
Company by providing incentive awards to Key Employees and Consultants
(including officers and Directors who are also employees), whose
responsibilities and decisions directly affect their performance of the Company.
Such incentive awards may consist of Stock or, in the discretion of the
Committee, Options to purchase such Stock, or any combination of the foregoing,
all as the Committee may determine.

       2.3    Effective Date. The Intellon Corporation Incentive Plan became
effective on October 4, 1991. This Plan amends and restates such Intellon
Corporation Incentive Plan effective February 23, 1996.

       2.4    Participants. Only Key Employees or Consultants of the Company
shall be eligible to receive Stock or Options under the Plan.

                                   ARTICLE III

                               Plan Administration

       3.1    Committee. This Plan shall be administered by a committee of the
Board of Directors of the Company (the "Committee"). The Committee shall consist
of members of the Board designated by the Board from time to time, all of whom
shall be Disinterested Persons during the time that they serve on such
Committee. The Committee shall serve at the pleasure of the Board.

       3.2    Power of the Committee.

              (a)    Authority. The Committee shall have full authority and
discretion: (a) except with respect to Options covering the Employees and the
shares of Stock specified on Exhibit A attached hereto, to determine, consistent
with the provisions of this Plan, which of the Key Employees or Consultants will
be granted Awards, the form of Awards to be granted, the amount or number of
shares of Stock subject to each Award, and the terms and conditions of each
Award (which need not be identical): (i) to determine whether the Options
granted pursuant to this Plan shall be Incentive Stock Options or Nonstatutory
Stock Options; (ii) to construe and interpret the Plan; and (iii) to make all
other determinations and take all other actions deemed necessary or advisable
for the proper administration of the Plan. The Committee's decisions and
determinations under this Plan need not be uniform and may be made selectively
among Key Employees and Consultants whether or not such individuals are
similarly situated. All such actions and determinations shall be conclusively
binding upon all persons for all purposes. Unless otherwise indicated by the
Committee, Options granted pursuant to this Plan shall be Incentive Stock
Options.

              (b)    Proceedings. The Committee shall keep minutes of its
actions under the Plan. The act of a majority of the members present at a
meeting duly called and held shall be the act of the Committee. Any decision or
determination reduced to writing and signed by all members of the Committee
shall be fully effective as if made by unanimous vote at a meeting duly called
and held.

              (c)    Counsel and Consultants; Expenses. The Committee shall
employ such legal counsel, including, without limitation, independent legal
counsel and counsel regularly employed by the Company, consultants and agents as
the Committee may deem appropriate for the administration of this

                                      -3-
<PAGE>   4

Plan and may rely upon any opinion and computations received from any such
counsel or consultant. All expenses incurred by the Committee in interpreting
and administrating the Plan, including without limitation, meeting fees and
expenses and professional fees shall be paid by the Company.

              (d)    Indemnification. No member or former member of the
Committee or the Board shall be liable for any action or determination made in
good faith with respect to this Plan or any Award granted under it. Each member
or former member of the Committee or Board shall be indemnified and held
harmless by the Company against all costs or expense (including counsel fees) or
liability (including any sum paid in settlement of a claim with the approval of
the Board) arising out of any act or omission to act in connection with this
Plan unless arising out of such member's own fraud or bad faith. Such
indemnification shall be in addition to any rights of indemnification the
members or former members may have as directors or under the Bylaws of the
Company.

                                   ARTICLE IV

                         Shares of Stock Subject to Plan

       4.1    Limitations. Subject to adjustment pursuant to the provisions of
Section 4.3 hereof, the aggregate number of shares of Stock which may be issued
pursuant to the exercise of Options shall not exceed two million one hundred
seventy-five thousand (2,175,000) shares. Of the two million one hundred
seventy-five thousand (2,175,000) shares of Stock which may be issued and sold
hereunder pursuant to the exercise of Options, (i) one million three hundred
eighty-nine thousand five hundred (1,389,500) shares shall be covered by the
Options specified on Exhibit A attached hereto, which Options shall be Incentive
Stock Options or Nonstatutory Stock Options as indicated on Exhibit A, and have
been granted to the Key Employees or Consultants (and, as to each such
individual, shall cover the number of shares of Stock) specified on Exhibit A
attached hereto, and (ii) thirty-six thousand (36,000) shares have been issued
pursuant to the exercise of Options granted to the Key Employees or Consultant,
specified on Exhibit A attached hereto. Shares issued pursuant to the exercise
of Options may be either authorized and unissued shares or shares issued and
thereafter acquired by the Company.

       4.2    Options Granted Under Plan. Shares of Stock with respect to which
an Option granted hereunder shall have been exercised shall not again be
available for Option hereunder. If Options granted hereunder shall terminate for
any reason without being wholly exercised, then the Committee shall have the
discretion to grant new Options to Optionees hereunder covering the number of
shares to which such terminated Options related.

       4.3    Antidilution. If and to the extent that the number of issued Stock
shall be increased or reduced by a change in par value, split up,
reclassification, distribution of a dividend payable in shares, or the like, the
number of shares subject to Option and the Option Price for them shall be
proportionately adjusted. If the Company is reorganized or consolidated or
merged with another corporation, the Optionee shall be entitled to receive
options covering shares of such reorganized, consolidated or merged corporation
in the same proportion, or at an equivalent price, and subject to the same
conditions. For purposes of the preceding sentence, the excess of the fair
market value of the shares subject to the Option immediately after the
reorganization, consolidation or merger over the aggregate Option Price of such
shares shall not be more than the excess of the aggregate fair market value of
all shares subject to the Option immediately before such reorganization,
consolidation or merger over the aggregate Option Price of such shares. A new
option or assumption of the old option shall not give the Optionee additional
benefits which he or she did not have under the old option.

                                      -4-
<PAGE>   5

                                    ARTICLE V

                                Award and Options

       5.1    Award Grant and Agreement. Each Award granted hereunder shall be
evidenced by minutes of a meeting of the Committee authorizing the same and by a
written Award Agreement dated as of the date of grant and executed by the
Company and the Optionee, which Award Agreement shall set forth such terms and
conditions as may be determined by the Committee to be consistent with this Plan
and shall indicate whether the Option that it evidences is intended to be an
Incentive Stock Option or a Nonstatutory Stock Option; provided, however, that
the Options to be granted to the individuals (and, as to each such individual,
to cover the number of shares of Stock) specified on Exhibit A attached hereto
shall not be required to be evidenced by minutes of a meeting of the Committee
authorizing the same.

       5.2    Option Price. The Option Price of each share of Stock subject to
an Incentive Stock Option shall be the fair market value of the Stock on the
date of grant (and, as to any Nonstatutory Stock Option, shall be the Option
Price as determined by the Committee). If the Stock is publicly held and
actively traded in an established market on the date of grant, then the fair
market value of the Stock on the date of grant shall be determined by the
Committee by any reasonable method using market quotations. If the Stock is not
publicly held and actively traded in an established market on the date of grant,
then the fair market value of the Stock on the date of grant shall be determined
in good faith by the Committee using any reasonable method.

       5.3    Option Exercise. Options may be exercised in whole or in part from
time to time with respect to whole shares only, within the period permitted for
the exercise thereof. Notwithstanding any other provision in this Plan, no
option granted under the Plan may be exercised more than ten (10) years after
the date on which it is granted. No part of any Option may be exercised until
the Optionee shall have remained in the employ of the Company (or, as to the
Consultant, been retained by the Company) for the period designated by the
Committee, if any, after the date on which the Optionee is granted. Options
shall be exercised by: (i) written notice of intent to exercise the Option with
respect to a specific number of shares of Stock which is delivered by hand
delivery or registered or certified mail, return receipt requested, to the
Company at its principal office; and (ii) payment in full (by a check or money
order payable to "Intellon Corporation") to the Company at such office of the
amount of the Option Price for the number of shares of Stock with respect to
which the Option is then being exercised. The Committee shall have the right to
determine whether the Option Price may be paid to the Company in consideration
(other than cash) as the Committee deems appropriate, including Stock already
owned by the Optionee, having a total fair market value, as determined by the
Committee, equal to the purchase price of the Stock, or a combination of cash
and such other consideration having a total fair market value, as so determined,
equal to such purchase price. In addition to and at the time of payment of the
Option Price, the Optionee shall pay to the Company in cash the full amount of
all federal, state, and local withholding or other employment taxes, if any,
applicable to the taxable income of the Optionee resulting from such exercise,
and any sales, transfer, or similar taxes imposed with respect to the issuance
or transfer of shares of Stock in connection with such exercise.

       5.4    Nontransferability of Option. No Option shall be transferred by an
Optionee otherwise than by will or the laws of descent and distribution. During
the lifetime of an Optionee, the Option shall be exercisable only by him or by
his legal guardian or personal representative.

                                      -5-
<PAGE>   6

       5.5    Effect of Death, Disability, Retirement, or Other Termination of
Service.

              (a)    Death. If the Employee's employment with the Company
terminates as a result of his or her death, the Employee's personal
representative or administrator of the estate of the Employee (or the person or
persons to whom the Option shall have been validly transferred by the personal
representative or the administrator pursuant to the Employee's Will or the laws
of descent and distribution, as the case may be) may exercise the Option as to
any shares not previously exercised during his or her lifetime within twelve
(12) months following the date of his or her death.

              (b)    Total Disability. If the Employee's employment with the
Company terminates as a result of his or her Total Disability, the Employee may
exercise the Option as to any vested shares not previously exercised within
twelve (12) months following the date of the termination of his or her
employment. Notwithstanding the foregoing, if the Employee dies within three (3)
months after termination of his or her employment with the Company because of
his or her Total Disability, the Employee's personal representative or
administrator of the estate of the Employee (or the person or persons to whom
the Option shall have been validly transferred by the personal representative or
the administrator pursuant to the Employee's Will or the laws of descent and
distribution, as the case may be) may exercise the Option as to any shares not
previously exercised during his or her lifetime within twelve (12) months
following the date of his or her death.

              (c)    Other Terminations of Employment. If the Employee's
employment with the Company is terminated for any reason other than his or her
death or Total Disability, he or she may exercise the Option as to any vested
shares not previously exercised within three (3) months following the date of
his or her separation from Service.

       5.6    Vesting and Exercise of Options.

              (a)    Vesting. Each Option shall vest in accordance with such
schedule as the Committee shall determine upon the Award of the Option.

              (b)    Change of Control. Notwithstanding any other provision,
upon any Change of Control 100% of the Option shall be deemed to be fully
exercisable immediately prior to said Change of Control.

              (c)    Death. Notwithstanding any other provision, if at least 40%
of the Option granted to an Optionee is exercisable in accordance with the terms
of the Option, then upon the death of the Employee, 100% of the Option shall be
deemed to be fully exercisable immediately prior to the Employee's death.

              (d)    Initial Public Offering. Notwithstanding any other
provision, in the event of an underwritten registration of an offering of
equities securities of the Company, 100% of the Option shall be deemed to become
fully exercisable upon the effectiveness of such registration.

       5.7    Rights as Shareholder. An Optionee or any permitted transferee of
an Option shall have no rights as a shareholder with respect to any shares of
Stock subject to such Option prior to the purchase of such shares by exercise of
such Option as provided herein.

       5.8    Investment Intent. Upon or prior to the exercise of all or any
portion of an Option, the Optionee shall furnish to the Company in writing such
information or assurances as, in the Company's opinion, may be necessary to
enable it to comply fully with the Securities Act of 1933, as amended, and

                                      -6-
<PAGE>   7

the rules and regulations thereunder and any other applicable statutes, rules,
and regulations. Without limiting the foregoing, if a registration statement is
not in effect under the Securities Act of 1933, as amended, with respect to the
shares of Stock to be issued upon exercise of an Option, the Company shall have
the right to require, as a condition to the exercise of such Option, that the
Optionee represent to the Company in writing that the shares to be received upon
exercise of such Option will be acquired by the Optionee for investment and not
with a view to distribution and that the Optionee agree, in writing, that such
shares will not be disposed of except pursuant to an effective registration
statement, unless the Company shall have received an opinion of counsel
reasonably acceptable to it to the effect that such disposition is exempt from
the registration requirements of the Securities Act of 1933, as amended. The
Company shall have the right to endorse on certificates representing shares of
Stock issued upon exercise of an Option such legends referring to the foregoing
representations and restrictions or any other applicable restrictions on resale
or disposition as the Company, in its discretion, shall deem appropriate.

                                   ARTICLE VI

                             Incentive Stock Options

       6.1    Requirements. All Incentive Stock Options granted pursuant to the
terms of this Plan shall be subject to the additional limitations and
restrictions as set forth in the Code and in this Article VI. Any Option granted
pursuant to this Plan which does not fulfill all of the provisions of this
Article VI shall not be an Incentive Stock Option and thus shall be a
Nonstatutory Stock Option.

       6.2    Grant Period. All Incentive Stock Options granted hereunder must
be granted within ten (10) years from the earlier of: (a) the date this Plan is
adopted by the Board; or (b) the date this Plan is approved by the shareholders
of the Company.

       6.3    Eligibility. The Committee shall determine which Employees shall
receive Incentive Stock Options. No member of the Committee is eligible to
receive Incentive Stock Options. Incentive Stock Options may not be granted to
any Employee who, at the time the Incentive Stock Option is granted, owns stock
possessing more than ten percent (10%) of the total combined voting power of all
classes of stock of the Company unless: (a) such Incentive Stock Option by its
terms is not exercisable after the expiration of five (5) years from the date of
its grant; and (b) the Option Price of the shares covered by such Incentive
Stock Option is not less than one hundred and ten percent (110%) of the fair
market value of such shares on the date that such Incentive Stock Option is
granted.

                                   ARTICLE VII

                           Nonstatutory Stock Options

       The Committee may grant Nonstatutory Stock Options under this Plan. Such
Nonstatutory Stock Options must fulfill all of the requirements of all
provisions of this Plan except for those contained in Article VI hereof. Subject
to the approval and acceptance of the Committee, any Optionee who is granted a
Nonstatutory Stock Option pursuant to this Plan shall be entitled to elect to
surrender all or any part of such Nonstatutory Stock Option to the Company and
receive, in exchange, an Incentive Stock Option covering the same number of
shares as those with respect to which the Nonstatutory Stock Option was
surrendered. Any such election shall be valid and effective only upon its
approval and acceptance by the Committee.

                                  ARTICLE VIII

                               Stock Certificates

       The Company shall not be required to issue or deliver any certificate for
shares of Stock purchased upon the exercise of any Option granted hereunder or
of any portion thereof, prior to fulfillment of all of the following conditions:

              (a)    The admission of such shares to listing on all stock
              exchanges on which the Stock is then listed, if any;

              (b)    The completion of any registration or other qualification
of such shares under any federal or state law or under the rulings or
regulations of the Securities and Exchange Commission or any other governmental
regulatory agency, which the Company shall in its sole discretion determine to
be necessary or advisable;

              (c)    The obtaining of any approval or other clearance from any
federal or state governmental agency which the Company shall in its sole
discretion determine to be necessary or advisable; and

              (d)    The lapse of such reasonable period of time following the
exercise of the Option as the Company from time to time may establish for
reasons of administrative convenience.

                                   ARTICLE IX

                      Loans and Supplemental Cash Payments

       The Committee may provide for supplemental cash payments or loans to
Employees at such time and in such manner as the Committee may determine in
connection with Awards granted under the Plan. Supplemental cash payments shall
be subject to such terms and conditions as the Committee may specify; provided,
however, in no event shall the amount of such payment exceed the fair market
value of the shares of Stock purchased through an Option on the date of
exercise; provided further, that no supplemental cash payment shall be made if
it would disqualify such Option as being an Incentive Stock Option. In the case
of loans, any such loans shall be evidenced by a written loan agreement or other
instrument in such form and shall contain such terms and conditions, including
without limitation, provisions for interest, payment schedules, collateral,
forgiveness, events of default or acceleration of such loans or parts thereof,
as the Committee shall specify; provided, however, that in the case of an
Option, the interest rate set by the Committee under such an arrangement shall
be no lower than that required to avoid the imputation of unstated interest
under the Code and the Committee shall specify no such terms or conditions that
would result in such Option failing to qualify as an Incentive Stock Option.

                                    ARTICLE X

                Termination, Amendment, and Modification of Plan

       The Board may at any time terminate, and may at any time and from time to
time and in any respect amend or modify, the Plan; provided, however, that no
such action of the Board without approval of the shareholders of the Company may
increase the total number of shares of Stock subject to the Plan except as
contemplated in Section 4.3 hereof or alter the class of persons eligible to
receive Options

                                      -8-
<PAGE>   9

under the Plan, and provided further that no termination, amendment, or
modification of the Plan shall without the written consent of the Optionee of
such Option adversely affect the rights of the Optionee with respect to an
Option or the unexercised portion thereof.

                                   ARTICLE XI

                                  Miscellaneous

       11.1   Service. Nothing in this Plan or in any Option granted hereunder
or in any Award Agreement relating thereto shall confer upon any Employee the
right to continue in the Service of the Company or interfere in any way with the
right of the Company to terminate the Employee's employment at any time.

       11.2   Other Compensation Plans. The adoption of this Plan shall not
affect any other stock option or incentive or other compensation plans in effect
for the Company, nor shall this Plan preclude the Company from establishing any
other forms of incentive or other compensation for directors, officers, or
employees of the Company. No Award under this Plan shall be deemed salary or
compensation for the purpose of computing benefits under any employee benefit
plan or other arrangement of the Company for the benefit of its employees unless
the Company shall determine otherwise. No individual shall have any claim to an
Award until it is actually granted under the Plan.

       11.3   Absence. Absence on leave approved by a duly constituted officer
of the Company shall not be considered interruption or termination of employment
for purposes of this Plan; provided, however, that no Award may be granted to an
Employee while he or she is absent on leave.

       11.4   Other Distribution. If the Committee finds that any person to whom
any Award, or portion thereof, is payable under this Plan is unable to care for
his or her affairs because of illness or accident, or is a minor, then any
payment due him or her (unless a prior claim therefor has been made by a duly
appointed legal representative) may, if the Committee so directs the Company, be
paid to his or her spouse, a child, a relative, an institution maintaining or
having custody of such person, or any other person deemed by the Committee to be
a proper recipient on behalf of such person otherwise entitled to payment. Any
such payment shall be a complete discharge of the liability of the Company
therefor.

       11.5   No Assignment. The right of any Key Employee or Consultant or
other person to any Award payable under this Plan may not be assigned,
transferred, pledged or encumbered, either voluntarily or by operation of law,
except as may otherwise be required by law. If, by reason or any attempted
assignment, transfer, pledge, or encumbrance, or any bankruptcy or any other
event happening at any time, any amount payable under the Plan would be made
subject to the debts or liabilities of the Key Employee or Consultant or his or
her heirs or assigns or would otherwise devolve upon anyone else and not be
enjoyed by the Key Employee or Consultant or his or her heirs or assigns, then
the Committee may terminate such person's interest in any such payment and
direct that the same be held and applied to or for the benefit of the Key
Employee or Consultant, his or her heirs or assigns or any other persons deemed
to be the natural objects of his or her bounty, taking into account the
expressed wishes of the Key Employee or Consultant (or, in the event of his or
her death, those of his or her heirs or assigns) in such manner as the Committee
may deem proper.

       11.6   Withholding. The Committee may cause to be made, as a condition
precedent to the payment of any Award, or otherwise, appropriate arrangements
with the Key Employee or Consultant or his or her beneficiary, for the
withholding of any federal, state, local or foreign taxes.

                                      -9-
<PAGE>   10

       11.7   Elections. All elections, designations, requests, notices,
instructions and other communications from a Key Employee or Consultant,
beneficiary or other person to the Committee, required or permitted under this
Plan, shall be in such form as is prescribed from time to time by the Committee
and shall be mailed by first-class mail or delivered to such location as shall
be specified by the Committee.

       11.8   Captions. The captions preceding the sections hereof are inserted
solely as a matter of convenience and in no way define or limit the scope of
intent of any provision hereof.

       11.9   Plan Binding on Successors. The Plan shall be binding upon the
successors and assigns of the Company.

       11.10  Singular, Plural, Gender. Whenever used herein, nouns in the
singular shall include the plural, and the masculine pronoun shall include the
feminine gender.

       11.11  Applicable Law. This Plan shall be governed by and construed in
accordance with the laws of the State of Florida.

       11.12  Severability. If any provision or provisions of this Plan shall be
held to be invalid, illegal, or unenforceable, the validity, legality, and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

       11.13  Interpretation. All Awards granted pursuant to this Plan are
subject to all interpretations, amendments, rules and regulations which may from
time to time be promulgated and adopted pursuant to this Plan.

                                  CERTIFICATION

       The undersigned Secretary of the Company does hereby certify that the
Plan was duly adopted by the Board of Directors on February 23, 1996, and by the
shareholders of the Company on March 15, 1996.
