                    c. for an agreement by the Optionee or Grantee to resell to
                    the Corporation, under specified conditions, Shares issued

                    Stock-Based Award;

                    d. for the right of the Optionee to surrender to the
                    Corporation an Option (or a portion thereof) that has become
                    exercisable and receive upon such surrender, without any
                    payment to the Corporation or a Subsidiary (other than

                    with respect to the Option) that number of Shares (equal to
                    the highest whole number of Shares) having an aggregate Fair
                    Market Value as of the date of surrender equal to that
                    number of Shares subject to the Option (or portion thereof)
                    being surrendered multiplied by an amount equal to the

<Page>

                    of surrender over (ii) the Option Price, plus an amount of
                    cash equal to the Fair Market Value of any fractional Share
                    to which the Optionee might be entitled; any such surrender
                    shall be treated as the exercise of the Option (or portion
                    thereof); and

                    e. for the automatic issuance of a Reload Option covering a

                  exercise or acquisition, the making of any representations or
                  agreements which the Committee may deem necessary or advisable

                  States or of any state; and

         F.       to make all other determinations and take all other actions
                  necessary or advisable for the administration of the Plan.

                  the Option is intended to be a nonstatutory stock option and

                  Code.

         C.       The Option Period shall be determined by the Committee and
                  specifically set forth in the Agreement, provided, however,
                  that an Option shall not be exercisable before six months from
                  the Date of Grant (except that this limitation need not apply

                  period) and no Option shall be exercisable after ten years
                  after the Date of Grant.

                  Optionee agrees, for the Optionee and his or her successors,

                  offer of Common Stock to the Optionee under the Plan, unless
                  the Corporation agrees to permit such exercise, and that, upon
                  the issuance of any Shares upon the exercise of the Option,
                  the Optionee will, upon the request of the Corporation, agree
                  in writing that he or she is

                  acquiring such Shares for investment only and not with a view
                  to resale, and that he or she will not sell, pledge or
                  otherwise dispose of such Shares so issued unless and until
                  (i) the Corporation is furnished with an opinion of counsel to
                  the effect that registration of such Shares pursuant to the
                  Securities Act of 1933, as amended, is not required by that
                  Act and the rules and regulations thereunder; (ii) the staff
                  of the Securities and Exchange Commission has issued a
                  "no-action" letter with respect to such disposition; or (iii)
                  such registration or notification as is, in the opinion of
                  counsel for the Corporation, required for the lawful
                  disposition of such Shares has been filed by the Corporation
                  and has become effective; provided, however, that the
                  Corporation shall not be obligated to file any such
                  registration or notification. The Option shall further agree
                  that the Company may place a legend embodying such restriction
                  on the certificates evidencing such shares.

         E.       All other terms of Options granted under the Plan shall be
                  determined by the Committee in its sole discretion, as
                  exercised consistently with the terms of the Plan, and
                  specifically set forth in the Optionee's agreement. Any terms
                  of Options determined by the Committee that vary from the
                  express terms set forth in the Plan also shall be specifically
                  set forth in the Optionee's Agreement.

                  accompanied by full payment of the Option Price for the Shares
                  with respect to which the Option is exercised in accordance

                  Section 401(k) of the Code maintained by the Corporation or a
                  related party within the provisions of subsections (b), (c),
                  (m) or (o) of Section 414 of the Code.

8.       Nontransferability

         A. Except to the extent provided in Section 8.B below, Options granted
         under the Plan shall not be transferable otherwise than (a) by will or
         the laws of descent and distribution, or (b) pursuant to a qualified
         domestic relations order as defined in Section 414(p) of the Code or
         Title I of the Employee Retirement Income Security Act or the rules
         thereunder, and an Option may be exercised, during the Optionee's
         lifetime, only by the Optionee or, in the case of the Optionee's legal
         disability, by the Optionee's legal representative.

         B. If authorized in the applicable Agreement, an Optionee may transfer,
         not for value, all or part of an Option to any Family Member (as
         defined in this Section 8.B). For the purpose of this Section 8.B, a
         "not for value" transfer is a transfer which is (i) a gift, (ii) a
         transfer under a domestic relations order in settlement of marital

                                    Page 12
<Page>

         property rights; or (iii) a transfer to an entity in which more than
         fifty percent of the voting interests are owned by Family Members (or
         the Optionee) in exchange for an interest in that entity. Following a
         transfer under this Section 8.B), any such Option shall continue to be
         subject to the same terms and conditions as were applicable immediately
         prior to transfer. Subsequent transfers of transferred Options are
         prohibited except to Family Members of the original Optionee in
         accordance with this Section 8.B or by will or the laws of descent and
         distribution. The events of termination of employment or other
         relationship shall continue to be applied with respect to the original
         Optionee, following which the Option shall be exercisable by the
         transferee only to the extent, and for the periods specified with
         respect to the original Optionee. For purposes of Section 8.B, "Family
         Member" means a person who is a spouse, child, stepchild, grandchild,
         parent, stepparent, grandparent, sibling, niece, nephew, mother-in-law,
         father-in-law, son-in-law, daughter-in-law, brother-in-law, or
         sister-in-law, including adoptive relationships, of the Optionee, any
         person sharing the Optionee's household (other than a tenant or
         employee), a trust in which these persons have more than fifty percent
         of the beneficial interest, a foundation in which these persons (or the
         Optionee) control the management of assets, and any other entity in
         which these persons (or the Optionee) own more than fifty percent of
         the voting interests.

9.       Stock-Based Awards

                                    Page 13
<Page>

         A.       Subject to the provisions of this Plan, the Committee is
                  hereby authorized to make Stock-Based Awards to
                  Participants.

         B.       Shares underlying Stock-Based Awards shall be issued at such
                  times, subject to achievement of such performance or other
                  goals and on such other terms and conditions as the Committee
                  shall deem appropriate.

10.      Satisfaction of Withholding Tax Liabilities

         Each Optionee or Grantee must provide the Corporation with the means to
satisfy the Corporation's Withholding Tax Liabilities, with respect to any
income recognized by the Optionee or Grantee as a result of the exercise of an
Option or award of a Stock-Based Award (or the underlying Shares). Unless
otherwise determined by the Committee and specifically set forth in the
Optionee's or Grantee's Agreement, an Option or Grantee may satisfy Withholding
Tax Liabilities by (i) delivering cash to the Corporation, (ii) electing to have
the Corporation retain Shares otherwise issuable on the exercise of the Option
or pursuant to the award of a Stock-Based Award (other than Shares that are
subject to a substantial risk of forfeiture), (iii) delivering shares (other
than Shares that are subject to a substantial risk of forfeiture) to the
Corporation, or (iv) electing to satisfy Withholding Tax Liabilities through a
combination of clauses (i), (ii) or (iii) of this Article 10. Satisfaction of
Withholding Tax Liabilities also shall be accomplished under such additional
reasonable terms and conditions as the Committee deems appropriate.

                                    Page 14

Unless otherwise determined by the Committee and specifically set forth in the
Optionee's or Grantee's Agreement, in the case of an Insider who elects to
satisfy Withholding Tax Liabilities by having the Corporation retain Shares
otherwise issuable on the exercise of an Option or pursuant to a Stock-Based
Award, the Insider shall have the right to so satisfy Withholding Tax
Liabilities through (a) an irrevocable election made at least six months in
advance of the date on which the Withholding Tax Liabilities arise, and (b) if
the Withholding Tax Liabilities arise during the ten business day period
beginning on the third business day following the public release of the
Corporation's quarterly or annual earnings ("Window Period"), an irrevocable
election made during such Window Period.

11.      Capital Adjustments

         The number and class of Shares subject to each outstanding Option or
Stock-Based Award, the Option Price and the aggregate number and class of Shares
for which grants or awards thereafter may be made shall be equitably adjusted by
the Committee to reflect such events as stock dividends, stock splits,
extraordinary cash dividends, adoption of stock rights plans, split-ups,
split-offs, spin-offs, liquidations, combinations or exchange of shares,
recapitalizations, mergers, consolidations, reorganizations or any similar
transaction of or by the Corporation.

12.      Termination or Amendment

         The Board shall have the power to terminate the Plan and to amend it in
any respect, provided that, after the Plan has been approved by the shareholders
of the Company, the Board may not, without the approval of the shareholders

                                    Page 15
<Page>

of the Company if such approval is then required by applicable law, amend the
Plan so as to increase materially the number of Shares that may be issued under
the Plan (except as provided in Article 11), to modify materially the
requirements as to eligibility for participation in the Plan, or to increase
materially the benefits accruing to participants under the Plan. No termination
or amendment of the Plan shall, without his or her consent, adversely affect the
rights or obligations of any Optionee or Grantee.

13.      Modification, Extension and Renewal of Options

         Subject to the terms and conditions and within the limitations of the
Plan, the Committee may modify, extend or renew outstanding Options, or accept
the surrender of outstanding Options (to the extent not theretofore exercised)
granted under the Plan or under any other plan of the Corporation, or a company
or similar entity acquired by the Corporation or a Subsidiary, and authorize the
granting of new Options (to the extent not theretofore exercised), pursuant to
the Plan in substitution therefor and the substituted Options may specify a
lower exercise price than the surrendered Options, a longer term than the
surrendered Options or have any other provisions that are authorized by the
Plan. Subject to the terms and conditions and within the limitations of the
Plan, the Committee may modify the terms of any outstanding Agreement providing
for a Stock-Based Award. Notwithstanding the foregoing, however, no modification
of an Option granted under the Plan, or a Stock-Based Award, shall, without the
consent of the Optionee or Grantee, alter or impair any of the Optionee's or
Grantee's right or obligations.

14.      Effectiveness of the Plan

         The Plan and any amendments requiring shareholder approval pursuant to
Article 12 are subject to approval by vote of the shareholders of the
Corporation within 12 months after their adoption by the Board. Subject to that
approval, the Plan and any amendments are effective on the date on which they
are adopted by the Board. Options and Stock-Based Awards may be granted or
awarded prior to shareholder approval of the Plan or amendments requiring
shareholder approval, but each such Option grant or Stock-Based Award shall be
subject to the approval of the Plan or amendments by the shareholders. Except to
the extent required to satisfy the requirements of Rule 16b-3 under the Exchange
Act, the date on which any Option granted or Stock-Based Award awarded prior to
shareholder approval of the Plan or amendment requiring shareholder approval
shall be the Date of Grant for all purposes as if the Option or Stock-Based
Award had not been subject to shareholder approval. No Option may be exercised
prior to such shareholder approval, and any Stock-Based Award awarded shall be
forfeited if such shareholder approval is not obtained.

15.      Term of the Plan

         Unless sooner terminated by the Board pursuant to Article 12, the Plan
shall terminate on January 27, 2010, and no Options or Stock-Based Awards may be
granted after termination. The termination shall not affect the validity of any
Options or Stock-Based Awards outstanding on the date of termination.

16.      Indemnification of Committee

         In addition to such other rights of indemnification as they may have as
Directors or as members of the Committee, the members of the Committee shall be
indemnified by the Corporation against the reasonable expenses, including
attorneys' fees, actually and reasonably incurred in connection with the defense
of any action, suit or proceeding, or in connection with any appeal therein, to
which they or any of them may be a party by reason of any action taken or
failure to act under or in connection with the Plan or any Option or Stock-Based
Award granted or awarded hereunder, and against all amounts reasonably paid by
them in settlement thereof or paid by them in satisfaction or judgment in any
such action, suit or proceeding, if such members acted in good faith and in a
manner which they believed to be in, and not opposed to, the best interests of
the Corporation.

17.      General Provisions

         A.       The establishment of the Plan shall not confer upon any
                  Employee or Consultant  any legal or equitable right against
                  the Corporation, any Subsidiary or the Committee, except as
                  expressly provided in the Plan.

         B.       The Plan does not constitute inducement or consideration for
                  the employment of any Employee or the retention of any
                  Consultant, nor is it a contract between the Corporation or a
                  Subsidiary and any Employee or Consultant. Participation in
                  the Plan shall not give an Employee or Consultant any right to

                                    Page 18
<Page>

                  be retained in the service of the Corporation or Subsidiary.

         C.       The Corporation and its Subsidiaries may assume options,
                  warrants, or rights to purchase stock issued or granted by
                  other corporations whose stock or assets shall be acquired by
                  the Corporation or a Subsidiary, or which shall be merged into
                  or consolidated with the Corporation or a Subsidiary. Neither
                  the adoption of this Plan, nor its submission to the
                  shareholders, shall be taken to impose any limitations on the
                  powers of the Corporation or its affiliates to issue, grant,
                  or assume options, warrants, or rights, otherwise than under
                  this Plan, or to adopt other stock option or stock-based award
                  plans or to impose any requirement of shareholder approval
                  upon the same.

         D.       The interests of any Participant under the Plan are not
                  subject to the claims of creditors and may not, in any way,
                  be assigned, alienated or encumbered except as provided in
                  Article 8.

         E.       The Plan and each Agreement shall be governed, construed and
                  administered in accordance with the laws of the State
                  of Delaware.

         F.       The adoption of the Plan, the grant and exercise of Options
                  and the award of Stock-Based Awards shall be subject to
                  receipt of all required regulatory approvals, including
                  without limitation any required approvals of the Federal

                                    Page 19
<Page>

                  Communications Commission.

         G.       Should any provision of the Plan that is intended to comply
                  with the provisions of Rule 16b-3 under the Exchange Act at
                  the date of the adoption of the Plan by the Board not be
                  necessary for such compliance, or become no longer necessary
                  for such compliance, such provision of the Plan shall have no
                  force or effect under the Plan as of the date that such
                  provision is not required for purpose of satisfying the
                  provisions of Rule 16b-3 under the Exchange Act.
