all fiscal years following the date hereof, beginning with the 1999 fiscal year,
multiplied by (ii) the total number of shares subject to Tier 2 Options,
provided that the maximum cumulative number of shares subject to Tier 2 Options

become fully vested and exercisable immediately upon the earlier to occur of the
following: (1) any or all of the Tier 3 Options becoming fully vested and
exercisable, provided that if only 50% of the Tier 3 Options have vested and

         fiscal year prior to the fifth anniversary hereof, the aggregate EBITDA
         of the Company for the fiscal years following the date hereof equals or
         exceeds the Aggregate EBITDA Target.

                      (C) Tier 3 Options. The Company hereby grants to the

regarding the exercisability of this Option, the Tier 3 Options will vest and be
exercisable (except as provided below) only upon the first to occur of (x) a
Change in Control that satisfies the CIC Return Hurdle and (y) an Actual Sale or
Deemed Sale following a Qualified Public Offering that satisfies the QPO Return
Hurdle as hereinafter described. If on any date beginning six months after a
Qualified Public Offering the QPO Return Hurdle has been satisfied based on a
Deemed Sale at Fair Market Value as of such date, 50% of the Tier 3 Options will
vest and be immediately exercisable, and if on any date beginning 24 months

time after a Qualified Public Offering the QPO Return Hurdle is satisfied based
on an Actual Sale, 100% of the Tier 3 Options will vest and be immediately
exercisable. Notwithstanding the foregoing, the Tier 3 Options shall become

                  (ii) Options exercised in any one year shall be deducted from

shall be exercisable at the following times prior to the expiration date: (A) if
the Optionee is employed by the Company at the time of exercise, at any time by
giving the Company 45 days' advance written notice or (B) if the Optionee is not
employed by the Company at the time of exercise but has the right to exercise
after termination in accordance with Section 2(d) of this Agreement, by giving
the Company written notice at any time during the period specified in Section
2(d) of this Agreement, in which case the Option shall be deemed exercised as of
the end of the calendar month in which the Company received notice of exercise
of the Option. In either case, the notice of exercise shall specify the number
of Shares as to which the Option is being exercised.

                  (iii) Upon receipt of written notice of exercise by the
Company, the Company shall, upon full payment in cash to the Company of the
Exercise Price of the Shares as to which the Option shall be exercised and upon
receipt of a duly executed shareholders agreement (in the form attached hereto
as Exhibit A or in such other form as the Company may reasonably require), issue

Optionee pursuant to the preceding sentence shall be made by the Company within
90 days after the date of exercise. For purposes of this Agreement, the fair
market value of Shares shall be determined by such methods or procedures as
shall be established from time to time by the Board acting in its sole
discretion and in good faith. In making such determinations, the Board may rely
on a valuation report by an investment banking or valuation firm selected by the
Board. The Committee established by the Board to administer the Plan (the
"Committee") may, in its sole discretion, permit the Optionee to pay the
Exercise Price in previously acquired Shares rather than in cash.

                  (d) Exercise Upon Death or Termination of Employment.

                           (i) If the Optionee dies while an employee of the
Company, the Optionee's Designee may exercise the Option, to the extent it was
vested on the date of termination, by giving the Company written notice of such
exercise within 12 months


<PAGE>   7

after the date of Optionee's death, but in no event later than the Expiration
Date. An Optionee's "Designee" means the person designated by the Optionee in
his or her most recently filed beneficiary designation filed with the Company to
receive the Optionee's rights under the Plan upon the Optionee's death, or if
there is no such designation or no such designated person survives the Optionee,
by the person or persons to whom the Optionee's rights pass by will or
applicable law, or if no such person has such right, by his executors or
administrators.

                           (ii) If the Company shall terminate Optionee's
employment with the Company because of disability, the Optionee may exercise the
Option to the extent it was vested on the date of termination, by giving the
Company written notice of such exercise within 12 months after the date of
termination of employment, but in no event later than the Expiration Date.

                           (iii) If the Optionee terminates his employment with
the Company other than for Good Reason, the Optionee may exercise the Option to
the extent it was vested on the date of termination, by giving the Company
written notice of such exercise within 90 days after the date of termination of
employment, but in no event later then the Expiration Date. For purposes of this
Agreement, "Good Reason" has the meaning set forth in the executive severance or
employment agreement, if any, then in effect between the Company and the
Optionee or, in the absence of such agreement shall mean, if the basis for such
Good Reason is not cured within a reasonable period of time (determined in light
of the cure appropriate to the basis of such Good Reason, but in no event less
than 15 days), the failure of the Company to pay any undisputed amount due to
the Optionee in connection with his employment by the Company.

                           (iv) If the Optionee's employment shall terminate for
any reason other than death, disability or Cause (as hereinafter defined), or if
the Optionee shall terminate his employment with the Company for Good Reason,
the Optionee may exercise the Option to the extent it was vested on the date of
termination or, otherwise would have vested in the 12 months thereafter, in
either event according to the applicable vesting schedule in Section 2(c)(i), by
giving the Company written notice of such exercise within 18 months after the
date of termination of employment, but in no event later than the Expiration
Date. Notwithstanding the foregoing, the Optionee shall forfeit his right to
exercise any Options that would have vested within the 12 months after
termination, if the Optionee violates the terms regarding non-competition set
forth in the Optionee's executive severance or employment agreement.

                           (v) If the Optionee's employment shall terminate for
Cause, all right to exercise the Option shall terminate at the date of such
termination of employment. For purposes of this Agreement, "Cause" has the
meaning set forth in the executive severance or


<PAGE>   8

employment agreement, if any, then in effect between the Company and the
Optionee or, in the absence of such agreement, shall mean (i) the Optionee's
conviction of, or plea of guilty or nolo contendere to, a felony, (ii) the
Optionee's gross negligence in the performance of his duties and obligations to
the Company, which is not corrected within 15 business days after written
notice, (iii) the Optionee's knowingly dishonest act, or knowing bad faith or
willful misconduct in the performance of his duties and obligations to the
Company to the material detriment of the Company, which is not corrected within
15 business days after written notice, or (iv) the Optionee's other material
breach of his obligations under this Agreement, which is not corrected within a
reasonable period of time (determined in light of the cure appropriate to such
material breach, but in no event less than 15 business days) after written
notice.

                           (vi) In the event of termination of employment, if an
Incentive Stock Option is exercised after the expiration of the exercise periods
that apply for purpose of Section 422 of the Code, such stock option shall
thereafter be treated as a nonqualified stock option.

                  (e) Transferability. Except as otherwise provided in this
Section, the Option is not transferable other than as designated by the Optionee
in his or her most recently filed Beneficiary designation filed with the
Company, or if there is no such designation or no such designated person
survives the Optionee, as designated by the Optionee, by will or by the laws of
descent and distribution, and during the Optionee's life, may be exercised only
by the Optionee. However, an Optionee, with the approval of the Committee, may
transfer the Option for no consideration to or for the benefit of the Optionee's
Immediate Family or to a partnership or limited liability company for one or
more members of the Optionee's Immediate Family, subject to such limits as the
Committee may establish, and the transferee shall remain subject to all the
terms and conditions applicable to Options prior to such transfer. The foregoing
right to transfer the Option shall apply to the right to consent to amendments
to this Agreement and, in the discretion of the Committee, shall also apply to
the right to transfer ancillary rights associated with the Option. The term
"Immediate Family" shall mean the Optionee's spouse, parents, children,
stepchildren, adoptive relationships, sisters, brothers, nieces, nephews and
grandchildren (and, for this purpose, shall also include the Optionee).

                  (f) Adjustments. In the event of any change in corporate
capitalization (including, but not limited to, a change in the number of shares
of Common Stock outstanding), such as a stock split or a corporate transaction,
such as any merger, consolidation, separation, including a spin-off, or other
distribution of stock or property of the Company, any reorganization (whether or
not such reorganization comes within the definition of such term in Section 368
of the Code) or any partial or complete


<PAGE>   9

liquidation of the Company, the Committee or Board may make such substitution or
adjustments in the number, kind and option price of shares subject to the Option
and/or such other equitable substitution or adjustments as it may determine to
be appropriate in its sole discretion; provided, however, that the number of
shares subject to the Option shall always be a whole number. In the event of a
corporate merger, consolidation, acquisition of property or stock, separation,
reorganization or liquidation, the Board shall be authorized to cause the

Target") and the numerator of which is the aggregate EBITDA of the Company for
all fiscal years following the date hereof, beginning with the 1999 fiscal year,
multiplied by (ii) the total number of shares subject to Tier 2 Options,
provided that the maximum cumulative number of shares subject to Tier 2 Options
that shall be vested in any fiscal year shall not exceed the product of (1) the

cumulative number of shares subject to Tier 2 Options that shall be vested as of

become fully vested and exercisable immediately upon the earlier to occur of the

         fiscal year prior to the fifth anniversary hereof, the aggregate EBITDA
         of the Company for the fiscal years following the date hereof equals or
         exceeds the Aggregate EBITDA Target.

exercisable (except as provided below) only upon the first to occur of (x) a
Change in Control that satisfies the CIC Return Hurdle and (y) an Actual Sale or
Deemed Sale following a Qualified Public Offering that satisfies the QPO Return
Hurdle as hereinafter described. If on any date beginning six months after a
Qualified Public Offering the QPO Return Hurdle has been satisfied based on a
Deemed Sale at Fair Market Value as of such date, 50% of the Tier 3 Options will
vest and be immediately exercisable, and if on any date beginning 24 months

on an Actual Sale, 100% of the Tier 3 Options will vest and be immediately
exercisable. Notwithstanding the foregoing, the Tier 3 Options shall become

giving the Company 45 days' advance written notice or (B) if the Optionee is not
employed by the Company at the time of exercise but has the right to exercise
after termination in accordance with Section 2(d) of this Agreement, by giving
the Company written notice at any time during the period specified in Section
2(d) of this Agreement, in which case the Option shall be deemed exercised as of

on a valuation report by an investment banking or valuation firm selected by the
Board. The Committee established by the Board to administer the Plan (the

Exercise Price in previously acquired Shares rather than in cash.

Plan upon the Optionee's death, or if there is no such designation or no such
designated person survives the Optionee, by the person or persons to whom the
Optionee's rights pass by will or applicable law, or if no such person has such
right, by his executors or administrators.

                           (ii) If the Company shall terminate Optionee's
employment with the Company because of disability, the Optionee may exercise the
Option to the extent it was vested on the date of termination, by giving the
Company written notice of such exercise within 12 months after the date of
termination of employment, but in no event later than the Expiration Date.

                           (iii) If the Optionee terminates his employment with
the Company other than for Good Reason, the Optionee may exercise the Option to
the extent it was vested on the date of termination, by giving the Company
written notice of such exercise within 90 days after the date of termination of
employment, but in no event later then the Expiration Date. For purposes of this
Agreement, "Good Reason" has the meaning set forth in the executive severance or
employment agreement, if any, then in effect between the Company and the
Optionee or, in the absence of such agreement shall mean, if the basis for such
Good Reason is not cured within a reasonable period of time (determined in light
of the cure appropriate to the basis of such Good Reason, but in no event less
than 15 days), the failure of the Company to pay any undisputed amount due to
the Optionee in connection with his employment by the Company.

                           (iv) If the Optionee's employment shall terminate for
any reason other than death, disability or Cause (as hereinafter defined), or if
the Optionee shall terminate his employment with the Company for Good Reason,
the Optionee may exercise the Option to the extent it was vested on the date of
termination or, otherwise would have vested in the 12 months thereafter, in
either event according to the applicable vesting schedule in Section 2(c)(i), by
giving the Company written notice of such exercise within 18 months after the
date of termination of employment, but in no event later than the Expiration
Date. Notwithstanding the foregoing, the Optionee shall forfeit his right to
exercise any Options that would have vested within the 12 months after
termination, if the Optionee violates the terms regarding non-competition set
forth in the Optionee's executive severance or employment agreement.

                           (v) If the Optionee's employment shall terminate for
Cause, all right to exercise the Option shall terminate at the date of such
termination of employment. For purposes of this Agreement, "Cause" has the
meaning set forth in the executive severance or employment agreement, if any,
then in effect between the Company and the Optionee or, in the absence of such
agreement, shall mean (i) the


<PAGE>   20

Optionee's conviction of, or plea of guilty or nolo contendere to, a felony,
(ii) the Optionee's gross negligence in the performance of his duties and
obligations to the Company, which is not corrected within 15 business days after
written notice, (iii) the Optionee's knowingly dishonest act, or knowing bad
faith or willful misconduct in the performance of his duties and obligations to
the Company to the material detriment of the Company, which is not corrected
within 15 business days after written notice, or (iv) the Optionee's other
material breach of his obligations under this Agreement, which is not corrected
within a reasonable period of time (determined in light of the cure appropriate
to such material breach, but in no event less than 15 business days) after
written notice.

                           (vi) In the event of termination of employment, if an
Incentive Stock Option is exercised after the expiration of the exercise periods
that apply for purpose of Section 422 of the Code, such stock option shall
thereafter be treated as a nonqualified stock option.

                  (e) Transferability. Except as otherwise provided in this
Section, the Option is not transferable other than as designated by the Optionee
in his or her most recently filed Beneficiary designation filed with the
Company, or if there is no such designation or no such designated person
survives the Optionee, as designated by the Optionee, by will or by the laws of
descent and distribution, and during the Optionee's life, may be exercised only
by the Optionee. However, an Optionee, with the approval of the Committee, may
transfer the Option for no consideration to or for the benefit of the Optionee's
Immediate Family or to a partnership or limited liability company for one or
more members of the Optionee's Immediate Family, subject to such limits as the
Committee may establish, and the transferee shall remain subject to all the
terms and conditions applicable to Options prior to such transfer. The foregoing
right to transfer the Option shall apply to the right to consent to amendments
to this Agreement and, in the discretion of the Committee, shall also apply to
the right to transfer ancillary rights associated with the Option. The term
"Immediate Family" shall mean the Optionee's spouse, parents, children,
stepchildren, adoptive relationships, sisters, brothers, nieces, nephews and
grandchildren (and, for this purpose, shall also include the Optionee).

                  (f) Adjustments. In the event of any change in corporate
capitalization (including, but not limited to, a change in the number of shares
of Common Stock outstanding), such as a stock split or a corporate transaction,
such as any merger, consolidation, separation, including a spin-off, or other
distribution of stock or property of the Company, any reorganization (whether or
not such reorganization comes within the definition of such term in Section 368
of the Code) or any partial or complete liquidation of the Company, the
Committee or Board may make such substitution or adjustments in the number, kind
and option price of shares subject to the Option and/or such other equitable
substitution or adjustments as it may determine to be appropriate in its sole
discretion; provided, however, that the number of shares subject to the Option
shall always be a whole number. In the event of a corporate merger,
consolidation, acquisition of property or stock, separation, reorganization or
liquidation, the Board shall be authorized to cause the Company to issue or
assume stock options, whether or not in transaction to which Section 424(a) of
the Code applies, by means of substitution of new


<PAGE>   21

stock options for previously issued stock options or an assumption of previously
issued stock options.

                  (g) No Rights as Stockholder. The Optionee shall have no
rights as a stockholder with respect to any Shares subject to the Option prior
to the date of issuance to the Optionee of a certificate or certificates for
such Shares.

                  (h) Optionee Acknowledgement.  The Optionee acknowledges that:

                           (i) the future value of the Company is highly
speculative;

                           (ii) the Optionee is not relying on the value of this
Option as current compensation;

                           (iii) the Company has no obligation to the Optionee
to sell the Company or to sell Shares publicly (which may have the effect of
reducing the value of the Company);

                           (iv) upon exercise of this Option, unless the Shares
issuable upon exercise of the Options have been registered under applicable
securities laws, there will be substantial restrictions on the transferability
of the Shares; and

                           (v) the past performance or experience of the
Company, the Company's officers, directors, agents, or employees, will not in
any way indicate or predict the results of the ownership of Shares or of the
Company's activities.

                  (i) No Right to Continued Employment. The Option shall not
confer upon the Optionee any right with respect to continuance of employment by
the Company, nor shall it interfere in any way with the right of the Optionee's
employer to terminate the Optionee's employment at any time.

                  (j) Compliance With Law and Regulations. The Option herein
granted and the obligation of the Company to sell and deliver shares hereunder,
shall be subject to all applicable Federal and State laws, rules and regulations
and to such approvals by any government or regulatory agency as may be required.
The Company shall not be required to issue or deliver any certificates for
Shares prior to (i) the listing of such Shares on any stock exchange or national
market quotations system on which the Shares may then be listed and (ii) the
completion of any registration or qualification of such Shares under any Federal
or State law, or any rule or regulation of any government body which the Company
shall, in its sole discretion, determine to be necessary or advisable. Moreover,
the Option herein granted may not be exercised if its exercise, or the receipt
of Shares pursuant hereto, would be contrary to applicable law.

Optionee [10,000] Tier 2 Options. Subject to the other terms of this Agreement
regarding the exercisability of this Option, the Tier 2 Options will vest and be
exercisable annually as of December 31 of each fiscal year of the Company with
respect to a cumulative number of shares in an amount equal to the product of
(i) a fraction, the denominator of which is 278,658,000 (the "Aggregate EBITDA
Target") and the numerator of which is the aggregate EBITDA of the Company for
all fiscal years following the date hereof, beginning with the 1999 fiscal year,
multiplied by (ii) the total number of shares subject to Tier 2 Options,
provided that the maximum cumulative number of shares subject to Tier 2 Options
that shall be vested in any fiscal year shall not exceed the product of (1) the
Applicable Percentage for such fiscal year multiplied by (2) the total number of
shares subject to Tier 2 Options. This calculation shall be made with respect to
each fiscal year, beginning with the 1999 fiscal year, based on the Company's
audited financial statements for such year. Notwithstanding the foregoing, (x)

disability, termination by the Company without Cause (as defined below) or
termination by the Optionee for Good Reason (as defined below), the aggregate
cumulative number of shares subject to Tier 2 Options that shall be vested as of
the termination date shall not be subject to any limitations imposed by the
Applicable Percentage and shall be equal to the product of (1) a fraction, the
denominator of which is the Aggregate EBITDA Target and the numerator of which
is the aggregate EBITDA of the Company for all fiscal years following the date
hereof, beginning with the 1999 fiscal year, multiplied by (2) the total number
of shares subject to Tier 2 Options, and (y) all of the Tier 2 Options shall
become fully vested and exercisable immediately upon the earlier to occur of the
following: (1) any or all of the Tier 3 Options becoming fully vested and
exercisable, provided that if only 50% of the Tier 3 Options have vested and
become exercisable, then only 50% of the then unvested Tier 2 Options shall vest
and become exercisable, and the remaining 50% of the unvested Tier 2 Options
shall vest and become exercisable immediately upon the vesting and

<PAGE>   28

         however, that the Applicable Percentage shall be 100% if following any
         fiscal year prior to the fifth anniversary hereof, the aggregate EBITDA
         of the Company for the fiscal years following the date hereof equals or
         exceeds the Aggregate EBITDA Target.

         depreciation, and amortization as reflected in the Company's audited
         financial statements. Adjustments for unusual items will be made in the

         Executive Officer of the Company.

                      (C) Tier 3 Options. The Company hereby grants to the
Optionee [15,000] Tier 3 Options. Subject to the other terms of this Agreement
regarding the exercisability of this Option, the Tier 3 Options will vest and be
exercisable (except as provided below) only upon the first to occur of (x) a
Change in Control that satisfies the CIC Return Hurdle and (y) an Actual Sale or
Deemed Sale following a Qualified Public Offering that satisfies the QPO Return
Hurdle as hereinafter described. If on any date beginning six months after a
Qualified Public Offering the QPO Return Hurdle has been satisfied based on a
Deemed Sale at Fair Market Value as of such date, 50% of the Tier 3 Options will
vest and be immediately exercisable, and if on any date beginning 24 months
after a Qualified Public Offering the QPO Return Hurdle has been satisfied based
on a Deemed Sale at Fair Market Value as of such date, the additional 50% of the
Tier 3 Options will vest and be immediately exercisable, except that, if at any
time after a Qualified Public Offering the QPO Return Hurdle is satisfied based
on an Actual Sale, 100% of the Tier 3 Options will vest and be immediately
exercisable. Notwithstanding the foregoing, the Tier 3 Options shall become
fully vested and exercisable upon the seventh anniversary of the date hereof.

         such period, and (iii) with respect to any other property, such value

         person or entity in respect of the Charlesbank Investment, through the
         date of determination, and subject to adjustment in the good faith
         discretion of the Board in the event of any merger, acquisition,
         consolidation, sale of assets, recapitalization, contribution of
         capital to, or redemption of stock of, the Company, or any other event
         that the Board deems relevant to the calculation of such return.

                      "QPO Return Hurdle" means (i) if the Actual Sale or Deemed
         Sale occurs within 18 months of the original investment by Charlesbank
         Equity Fund IV, Limited Partnership, a Return on Investment of 2.0x and
         (ii) if the Actual Sale or Deemed Sale occurs more than 18 months after
         the original investment by Charlesbank Equity Fund IV, Limited
         Partnership, a Return on Investment of 3.0x and a 30% IRR.

         Charlesbank Investment, and (ii) in the case of an Actual Sale or
         Deemed Sale following a Qualified Public Offering, the quotient of (A)
         the total amount of cash and freely tradeable securities (based on the

         to such Actual Sale or Deemed Sale, as the case may be, divided by (B)
         the Charlesbank Investment.

                  (ii) Options exercised in any one year shall be deducted from
the number of Options exercisable in any future year. Once vested, this Option
shall be exercisable at the following times prior to the expiration date: (A) if
the Optionee is employed by the Company at the time of exercise, at any time by
giving the Company 45 days' advance written notice or (B) if the Optionee is not
employed by the Company at the time of exercise but has the right to exercise
after termination in accordance with Section 2(d) of this Agreement, by giving
the Company written notice at any time during the period specified in Section
2(d) of this Agreement, in which case the Option shall be deemed exercised as of
the end of the calendar month in which the Company received notice of exercise
of the Option. In either case, the notice of exercise shall specify the number
of Shares as to which the Option is being exercised.

                  (iii) Upon receipt of written notice of exercise by the
Company, the Company shall, upon full payment in cash to the Company of the
Exercise Price of the Shares as to which the Option shall be exercised and upon
receipt of a duly executed shareholders agreement (in the form attached hereto
as Exhibit A or in such other form as the Company may reasonably require), issue
to the Optionee the Shares subject to the Option. Any issuance of Shares to an
Optionee pursuant to the preceding sentence shall be made by the Company within
90 days after the date of exercise. For purposes of this Agreement, the fair
market value of Shares shall be determined by such methods or procedures as
shall be established from time to time by the Board acting in its sole
discretion and in good faith. In making such determinations, the Board may rely
on a valuation report by an investment banking or valuation firm selected by the
Board. The Committee established by the Board to administer the Plan (the
"Committee") may, in its sole discretion, permit the Optionee to pay the
Exercise Price in previously acquired Shares rather than in cash.

                  (d) Exercise Upon Death or Termination of Employment.

                           (i) If the Optionee dies while an employee of the
Company, the Optionee's Designee may exercise the Option, to the extent it was
vested on the date of termination, by giving the Company written notice of such
exercise within 12 months


<PAGE>   31

after the date of Optionee's death, but in no event later than the Expiration
Date. An Optionee's "Designee" means the person designated by the Optionee in
his or her most recently filed beneficiary designation filed with the Company to
receive the Optionee's rights under the Plan upon the Optionee's death, or if
there is no such designation or no such designated person survives the Optionee,
by the person or persons to whom the Optionee's rights pass by will or
applicable law, or if no such person has such right, by his executors or
administrators.

                           (ii) If the Company shall terminate Optionee's
employment with the Company because of disability, the Optionee may exercise the
Option to the extent it was vested on the date of termination, by giving the
Company written notice of such exercise within 12 months after the date of
termination of employment, but in no event later than the Expiration Date.

                           (iii) If the Optionee terminates his employment with
the Company other than for Good Reason, the Optionee may exercise the Option to
the extent it was vested on the date of termination, by giving the Company
written notice of such exercise within 90 days after the date of termination of
employment, but in no event later then the Expiration Date. For purposes of this
Agreement, "Good Reason" has the meaning set forth in the executive severance or
employment agreement, if any, then in effect between the Company and the
Optionee or, in the absence of such agreement shall mean, if the basis for such
Good Reason is not cured within a reasonable period of time (determined in light
of the cure appropriate to the basis of such Good Reason, but in no event less
than 15 days), the failure of the Company to pay any undisputed amount due to
the Optionee in connection with his employment by the Company.

                           (iv) If the Optionee's employment shall terminate for
any reason other than death, disability or Cause (as hereinafter defined), or if
the Optionee shall terminate his employment with the Company for Good Reason,
the Optionee may exercise the Option to the extent it was vested on the date of
termination or, otherwise would have vested in the 12 months thereafter, in
either event according to the applicable vesting schedule in Section 2(c)(i), by
giving the Company written notice of such exercise within 18 months after the
date of termination of employment, but in no event later than the Expiration
Date. Notwithstanding the foregoing, the Optionee shall forfeit his right to
exercise any Options that would have vested within the 12 months after
termination, if the Optionee violates the terms regarding non-competition set
forth in the Optionee's executive severance or employment agreement.

                           (v) If the Optionee's employment shall terminate for
Cause, all right to exercise the Option shall terminate at the date of such
termination of employment. For purposes of this Agreement, "Cause" has the
meaning set forth in the executive severance or employment agreement, if any,
then in effect between the Company and the Optionee or, in the absence of such
agreement, shall mean (i) the Optionee's conviction of, or plea of guilty or
nolo contendere to, a felony, (ii) the Optionee's gross negligence in the
performance of his duties and obligations to the Company, which is not corrected
within 15 business days after written notice, (iii) the


<PAGE>   32

Optionee's knowingly dishonest act, or knowing bad faith or willful misconduct
in the performance of his duties and obligations to the Company to the material
detriment of the Company, which is not corrected within 15 business days after
written notice, or (iv) the Optionee's other material breach of his obligations
under this Agreement, which is not corrected within a reasonable period of time
(determined in light of the cure appropriate to such material breach, but in no
event less than 15 business days) after written notice.

                           (vi) In the event of termination of employment, if an
Incentive Stock Option is exercised after the expiration of the exercise periods
that apply for purpose of Section 422 of the Code, such stock option shall
thereafter be treated as a nonqualified stock option.

                  (e) Transferability. Except as otherwise provided in this
Section, the Option is not transferable other than as designated by the Optionee
in his or her most recently filed Beneficiary designation filed with the
Company, or if there is no such designation or no such designated person
survives the Optionee, as designated by the Optionee, by will or by the laws of
descent and distribution, and during the Optionee's life, may be exercised only
by the Optionee. However, an Optionee, with the approval of the Committee, may
transfer the Option for no consideration to or for the benefit of the Optionee's
Immediate Family or to a partnership or limited liability company for one or
more members of the Optionee's Immediate Family, subject to such limits as the
Committee may establish, and the transferee shall remain subject to all the
terms and conditions applicable to Options prior to such transfer. The foregoing
right to transfer the Option shall apply to the right to consent to amendments
to this Agreement and, in the discretion of the Committee, shall also apply to
the right to transfer ancillary rights associated with the Option. The term
"Immediate Family" shall mean the Optionee's spouse, parents, children,
stepchildren, adoptive relationships, sisters, brothers, nieces, nephews and
grandchildren (and, for this purpose, shall also include the Optionee).

                  (f) Adjustments. In the event of any change in corporate
capitalization (including, but not limited to, a change in the number of shares
of Common Stock outstanding), such as a stock split or a corporate transaction,
such as any merger, consolidation, separation, including a spin-off, or other
distribution of stock or property of the Company, any reorganization (whether or
not such reorganization comes within the definition of such term in Section 368
of the Code) or any partial or complete liquidation of the Company, the
Committee or Board may make such substitution or adjustments in the number, kind
and option price of shares subject to the Option and/or such other equitable
substitution or adjustments as it may determine to be appropriate in its sole
discretion; provided, however, that the number of shares subject to the Option
shall always be a whole number. In the event of a corporate merger,
consolidation, acquisition of property or stock, separation, reorganization or
liquidation, the Board shall be authorized to cause the Company to issue or
assume stock options, whether or not in transaction to which Section 424(a) of
the Code applies, by means of substitution of new stock options for previously
issued stock options or an assumption of previously issued stock options.


<PAGE>   33

                  (g) No Rights as Stockholder. The Optionee shall have no
rights as a stockholder with respect to any Shares subject to the Option prior
to the date of issuance to the Optionee of a certificate or certificates for
such Shares.

                  (h) Optionee Acknowledgement.  The Optionee acknowledges that:

                           (i) the future value of the Company is highly
speculative;

                           (ii) the Optionee is not relying on the value of this
Option as current compensation;

                           (iii) the Company has no obligation to the Optionee
to sell the Company or to sell Shares publicly (which may have the effect of
reducing the value of the Company);

                           (iv) upon exercise of this Option, unless the Shares
issuable upon exercise of the Options have been registered under applicable
securities laws, there will be substantial restrictions on the transferability
of the Shares; and

                           (v) the past performance or experience of the
Company, the Company's officers, directors, agents, or employees, will not in
any way indicate or predict the results of the ownership of Shares or of the
Company's activities.

                  (i) No Right to Continued Employment. The Option shall not
confer upon the Optionee any right with respect to continuance of employment by
the Company, nor shall it interfere in any way with the right of the Optionee's
employer to terminate the Optionee's employment at any time.

                  (j) Compliance With Law and Regulations. The Option herein
granted and the obligation of the Company to sell and deliver shares hereunder,
shall be subject to all applicable Federal and State laws, rules and regulations
and to such approvals by any government or regulatory agency as may be required.
The Company shall not be required to issue or deliver any certificates for
Shares prior to (i) the listing of such Shares on any stock exchange or national
market quotations system on which the Shares may then be listed and (ii) the
completion of any registration or qualification of such Shares under any Federal
or State law, or any rule or regulation of any government body which the Company
shall, in its sole discretion, determine to be necessary or advisable. Moreover,
the Option herein granted may not be exercised if its exercise, or the receipt
of Shares pursuant hereto, would be contrary to applicable law.

                      Notwithstanding the foregoing, all of the Tier 1
Options shall become fully vested and exercisable immediately upon the earlier
to occur of the following: (x) any or all of the Tier 3 Options becoming fully

         (iv) individuals serving as directors of the Company on the Effective
         Date (as defined in the Plan) and who were nominated or selected to

         individuals or directors whose election was previously so approved or
         (B) Principal Shareholders holding a majority of the aggregate voting
         power of the capital stock of the Company held by all Principal

         transaction or (vi) any other event or transaction that the Board deems

                      (B) Tier 2 Options. The Company hereby grants to the
Optionee [10,000] Tier 2 Options. Subject to the other terms of this Agreement
regarding the exercisability of this Option, the Tier 2 Options will vest and be
exercisable annually as of December 31 of each fiscal year of the Company with
respect to a cumulative number of shares in an amount equal to the product of
(i) a fraction, the denominator of which is 278,658,000 (the "Aggregate EBITDA
Target") and the numerator of which is the aggregate EBITDA of the Company for
all fiscal years following the date hereof, beginning with the 1999 fiscal year,
multiplied by (ii) the total number of shares subject to Tier 2 Options,
provided that the maximum cumulative number of shares subject to Tier 2 Options
that shall be vested in any fiscal year shall not exceed the product of (1) the
Applicable Percentage for such fiscal year multiplied by (2) the total number of
shares subject to Tier 2 Options. This calculation shall be made with respect to
each fiscal year, beginning with the 1999 fiscal year, based on the Company's
audited financial statements for such year. Notwithstanding the foregoing, (x)
if the Optionee's employment with the Company shall terminate because of death,
disability, termination by the Company without Cause (as defined below) or
termination by the Optionee for Good Reason (as defined below), the aggregate
cumulative number of shares subject to Tier 2 Options that shall be vested as of
the termination date shall not be subject to any limitations imposed by the
Applicable Percentage and shall be equal to the product of (1) a fraction, the
denominator of which is the Aggregate EBITDA Target and the numerator of which
is the aggregate EBITDA of the Company for all fiscal years following the date
hereof, beginning with the 1999 fiscal year, multiplied by (2) the total number
of shares subject to Tier 2 Options, and (y) all of the Tier 2 Options shall
become fully vested and exercisable immediately upon the earlier to occur of the
following: (1) any or all of the Tier 3 Options becoming fully vested and
exercisable, provided that if only 50% of the Tier 3 Options have vested and
become exercisable, then only 50% of the then unvested


<PAGE>   40

Tier 2 Options shall vest and become exercisable, and the remaining 50% of the
unvested Tier 2 Options shall vest and become exercisable immediately upon the
vesting and exercisability of the remaining 50% of the Tier 3 Options, and (2)
the seventh anniversary of the date hereof.

         however, that the Applicable Percentage shall be 100% if following any

                  (ii) Options exercised in any one year shall be deducted from
the number of Options exercisable in any future year. Once vested, this Option
shall be exercisable at the following times prior to the expiration date: (A) if
the Optionee is employed by the Company at the time of exercise, at any time by
giving the Company 45 days' advance written notice or (B) if the Optionee is not
employed by the Company at the time of exercise but has the right to exercise
after termination in accordance with Section 2(d) of this Agreement, by giving
the Company written notice at any time during the period specified in Section
2(d) of this Agreement, in which case the Option shall be deemed exercised as of
the end of the calendar month in which the Company received notice of exercise
of the Option. In either case, the notice of exercise shall specify the number
of Shares as to which the Option is being exercised.

                  (iii) Upon receipt of written notice of exercise by the
Company, the Company shall, upon full payment in cash to the Company of the
Exercise Price of the Shares as to which the Option shall be exercised and upon
receipt of a duly executed shareholders agreement (in the form attached hereto
as Exhibit A or in such other form as the Company may reasonably require), issue

Optionee pursuant to the preceding sentence shall be made by the Company within
90 days after the date of exercise. For purposes of this Agreement, the fair
market value of Shares shall be determined by such methods or procedures as
shall be established from time to time by the Board acting in its sole
discretion and in good faith. In making such determinations, the Board may rely
on a valuation report by an investment banking or valuation firm selected by the
Board. The Committee established by the Board to administer the Plan (the
"Committee") may, in its sole discretion, permit the Optionee to pay the
Exercise Price in previously acquired Shares rather than in cash.

                  (d) Exercise Upon Death or Termination of Employment.


<PAGE>   43

                           (i) If the Optionee dies while an employee of the
Company, the Optionee's Designee may exercise the Option, to the extent it was
vested on the date of termination, by giving the Company written notice of such
exercise within 12 months after the date of Optionee's death, but in no event
later than the Expiration Date. An Optionee's "Designee" means the person
designated by the Optionee in his or her most recently filed beneficiary
designation filed with the Company to receive the Optionee's rights under the
Plan upon the Optionee's death, or if there is no such designation or no such
designated person survives the Optionee, by the person or persons to whom the
Optionee's rights pass by will or applicable law, or if no such person has such
right, by his executors or administrators.

                           (ii) If the Company shall terminate Optionee's
employment with the Company because of disability, the Optionee may exercise the
Option to the extent it was vested on the date of termination, by giving the
Company written notice of such exercise within 12 months after the date of
termination of employment, but in no event later than the Expiration Date.

                           (iii) If the Optionee terminates his employment with
the Company other than for Good Reason, the Optionee may exercise the Option to
the extent it was vested on the date of termination, by giving the Company
written notice of such exercise within 90 days after the date of termination of
employment, but in no event later then the Expiration Date. For purposes of this
Agreement, "Good Reason" has the meaning set forth in the executive severance or
employment agreement, if any, then in effect between the Company and the
Optionee or, in the absence of such agreement shall mean, if the basis for such
Good Reason is not cured within a reasonable period of time (determined in light
of the cure appropriate to the basis of such Good Reason, but in no event less
than 15 days), the failure of the Company to pay any undisputed amount due to
the Optionee in connection with his employment by the Company.

                           (iv) If the Optionee's employment shall terminate for
any reason other than death, disability or Cause (as hereinafter defined), or if
the Optionee shall terminate his employment with the Company for Good Reason,
the Optionee may exercise the Option to the extent it was vested on the date of
termination or, otherwise would have vested in the 12 months thereafter, in
either event according to the applicable vesting schedule in Section 2(c)(i), by
giving the Company written notice of such exercise within 18 months after the
date of termination of employment, but in no event later than the Expiration
Date. Notwithstanding the foregoing, the Optionee shall forfeit his right to
exercise any Options that would have vested within the 12 months after
termination, if the Optionee violates the terms regarding non-competition set
forth in the Optionee's executive severance or employment agreement.

                           (v) If the Optionee's employment shall terminate for
Cause, all right to exercise the Option shall terminate at the date of such
termination of employment. For purposes of this Agreement, "Cause" has the
meaning set forth in the executive severance or employment agreement, if any,
then in effect between the Company and the Optionee or, in the absence of such
agreement, shall mean (i) the


<PAGE>   44

Optionee's conviction of, or plea of guilty or nolo contendere to, a felony,
(ii) the Optionee's gross negligence in the performance of his duties and
obligations to the Company, which is not corrected within 15 business days after
written notice, (iii) the Optionee's knowingly dishonest act, or knowing bad
faith or willful misconduct in the performance of his duties and obligations to
the Company to the material detriment of the Company, which is not corrected
within 15 business days after written notice, or (iv) the Optionee's other
material breach of his obligations under this Agreement, which is not corrected
within a reasonable period of time (determined in light of the cure appropriate
to such material breach, but in no event less than 15 business days) after
written notice.

                           (vi) In the event of termination of employment, if an
Incentive Stock Option is exercised after the expiration of the exercise periods
that apply for purpose of Section 422 of the Code, such stock option shall
thereafter be treated as a nonqualified stock option.

                  (e) Transferability. Except as otherwise provided in this
Section, the Option is not transferable other than as designated by the Optionee
in his or her most recently filed Beneficiary designation filed with the
Company, or if there is no such designation or no such designated person
survives the Optionee, as designated by the Optionee, by will or by the laws of
descent and distribution, and during the Optionee's life, may be exercised only
by the Optionee. However, an Optionee, with the approval of the Committee, may
transfer the Option for no consideration to or for the benefit of the Optionee's
Immediate Family or to a partnership or limited liability company for one or
more members of the Optionee's Immediate Family, subject to such limits as the
Committee may establish, and the transferee shall remain subject to all the
terms and conditions applicable to Options prior to such transfer. The foregoing
right to transfer the Option shall apply to the right to consent to amendments
to this Agreement and, in the discretion of the Committee, shall also apply to
the right to transfer ancillary rights associated with the Option. The term
"Immediate Family" shall mean the Optionee's spouse, parents, children,
stepchildren, adoptive relationships, sisters, brothers, nieces, nephews and
grandchildren (and, for this purpose, shall also include the Optionee).

                  (f) Adjustments. In the event of any change in corporate
capitalization (including, but not limited to, a change in the number of shares
of Common Stock outstanding), such as a stock split or a corporate transaction,
such as any merger, consolidation, separation, including a spin-off, or other
distribution of stock or property of the Company, any reorganization (whether or
not such reorganization comes within the definition of such term in Section 368
of the Code) or any partial or complete liquidation of the Company, the
Committee or Board may make such substitution or adjustments in the number, kind
and option price of shares subject to the Option and/or such other equitable
substitution or adjustments as it may determine to be appropriate in its sole
discretion; provided, however, that the number of shares subject to the Option
shall always be a whole number. In the event of a corporate merger,
consolidation, acquisition of property or stock, separation, reorganization or
liquidation, the Board shall be authorized to cause the Company to issue or
assume stock options, whether or not in transaction to which Section 424(a) of
the Code applies, by means of substitution of new


<PAGE>   45

stock options for previously issued stock options or an assumption of previously
issued stock options.

                  (g) No Rights as Stockholder. The Optionee shall have no
rights as a stockholder with respect to any Shares subject to the Option prior
to the date of issuance to the Optionee of a certificate or certificates for
such Shares.

                  (h) Optionee Acknowledgement.  The Optionee acknowledges that:

                           (i) the future value of the Company is highly
speculative;

                           (ii) the Optionee is not relying on the value of this
Option as current compensation;

                           (iii) the Company has no obligation to the Optionee
to sell the Company or to sell Shares publicly (which may have the effect of
reducing the value of the Company);

                           (iv) upon exercise of this Option, unless the Shares
issuable upon exercise of the Options have been registered under applicable
securities laws, there will be substantial restrictions on the transferability
of the Shares; and

                           (v) the past performance or experience of the
Company, the Company's officers, directors, agents, or employees, will not in
any way indicate or predict the results of the ownership of Shares or of the
Company's activities.

                  (i) No Right to Continued Employment. The Option shall not
confer upon the Optionee any right with respect to continuance of employment by
the Company, nor shall it interfere in any way with the right of the Optionee's
employer to terminate the Optionee's employment at any time.

                  (j) Compliance With Law and Regulations. The Option herein
granted and the obligation of the Company to sell and deliver shares hereunder,
shall be subject to all applicable Federal and State laws, rules and regulations
and to such approvals by any government or regulatory agency as may be required.
The Company shall not be required to issue or deliver any certificates for
Shares prior to (i) the listing of such Shares on any stock exchange or national
market quotations system on which the Shares may then be listed and (ii) the
completion of any registration or qualification of such Shares under any Federal
or State law, or any rule or regulation of any government body which the Company
shall, in its sole discretion, determine to be necessary or advisable. Moreover,
the Option herein granted may not be exercised if its exercise, or the receipt
of Shares pursuant hereto, would be contrary to applicable law.

regarding the exercisability of this Option, the Tier 2 Options will vest and be
exercisable annually as of December 31 of each fiscal year of the Company with
respect to a cumulative number of shares in an amount equal to the product of
(i) a fraction, the denominator of which is 278,658,000 (the "Aggregate EBITDA
Target") and the numerator of which is the aggregate EBITDA of the Company for
all fiscal years following the date hereof, beginning with the 1999 fiscal year,
multiplied by (ii) the total number of shares subject to Tier 2 Options,
provided that the maximum cumulative number of shares subject to Tier 2 Options
that shall be vested in any fiscal year shall not exceed the product of (1) the
Applicable Percentage for such fiscal year multiplied by (2) the total number of
shares subject to Tier 2 Options. This calculation shall be made with respect to
each fiscal year, beginning with the 1999 fiscal year, based on the Company's
audited financial statements for such year. Notwithstanding the foregoing, (x)
if the Optionee's employment with the Company shall terminate because of death,
disability, termination by the Company without Cause (as defined below) or
termination by the Optionee for Good Reason (as defined below), the aggregate
cumulative number of shares subject to Tier 2 Options that shall be vested as of
the termination date shall not be subject to any limitations imposed by the
Applicable Percentage and shall be equal to the product of (1) a fraction, the
denominator of which is the Aggregate EBITDA Target and the numerator of which
is the aggregate EBITDA of the Company for all fiscal years following the date
hereof, beginning with the 1999 fiscal year, multiplied by (2) the total number
of shares subject to Tier 2 Options, and (y) all of the Tier 2 Options shall
become fully vested and exercisable immediately upon the earlier to occur of the
following: (1) any or all of the Tier 3 Options becoming fully vested and
exercisable, provided that if only 50% of the Tier 3 Options have vested and

and become exercisable, and the remaining 50% of the unvested Tier 2 Options
shall vest and become exercisable immediately upon the vesting and
exercisability of the remaining 50% of the Tier 3 Options, and (2) the seventh
anniversary of the date hereof.

                  "Applicable Percentage" means with respect to (i) fiscal year
         1999, 20%, (2) fiscal year 2000, 40%, (3) fiscal year 2001, 60%, (4)

         however, that the Applicable Percentage shall be 100% if following any
         fiscal year prior to the fifth anniversary hereof, the aggregate EBITDA
         of


                                       3
<PAGE>   52

         the Company for the fiscal years following the date hereof equals or
         exceeds the Aggregate EBITDA Target.

                  "EBITDA" means earnings before interest, taxes, depreciation,
         and amortization as reflected in the Company's audited financial
         statements. Adjustments for unusual items will be made in the
         reasonable discretion of the Board, after consultation with the Chief
         Executive Officer of the Company.

                  (C)      Tier 3 Options. The Company hereby grants to the
Optionee [15,000] Tier 3 Options. Subject to the other terms of this Agreement
regarding the exercisability of this Option, the Tier 3 Options will vest and be
exercisable (except as provided below) only upon the first to occur of (x) a
Change in Control that satisfies the CIC Return Hurdle and (y) an Actual Sale or
Deemed Sale following a Qualified Public Offering that satisfies the QPO Return
Hurdle as hereinafter described. If on any date beginning six months after a
Qualified Public Offering the QPO Return Hurdle has been satisfied based on a
Deemed Sale at Fair Market Value as of such date, 50% of the Tier 3 Options will
vest and be immediately exercisable, and if on any date beginning 24 months
after a Qualified Public Offering the QPO Return Hurdle has been satisfied based
on a Deemed Sale at Fair Market Value as of such date, the additional 50% of the
Tier 3 Options will vest and be immediately exercisable, except that, if at any
time after a Qualified Public Offering the QPO Return Hurdle is satisfied based
on an Actual Sale, 100% of the Tier 3 Options will vest and be immediately
exercisable. Notwithstanding the foregoing, the Tier 3 Options shall become
fully vested and exercisable upon the seventh anniversary of the date hereof.

         (iii) with respect to any other property, such value determined as of

         Fund IV, Limited Partnership on the Charlesbank Investment as
         calculated by the use of an HP12c financial calculator, taking into
         account the timing and amount (based on the Fair Market Value thereof)

<PAGE>   54

         from the Company or any other person or entity in respect of the
         Charlesbank Investment prior to such Actual Sale or Deemed Sale, as the
         case may be, divided by (B) the Charlesbank Investment.

                  (ii)     Options exercised in any one year shall be deducted
from the number of Options exercisable in any future year. Once vested, this
Option shall be exercisable at the following times prior to the expiration date:
(A) if the Optionee is employed by the Company at the time of exercise, at any
time by giving the Company 45 days' advance written notice or (B) if the
Optionee is not employed by the Company at the time of exercise but has the
right to exercise after termination in accordance with Section 2(d) of this
Agreement, by giving the Company written notice at any time during the period
specified in Section 2(d) of this Agreement, in which case the Option shall be
deemed exercised as of the end of the calendar month in which the Company
received notice of exercise of the Option. In either case, the notice of
exercise shall specify the number of Shares as to which the Option is being
exercised.

                  (iii)    Upon receipt of written notice of exercise by the
Company, the Company shall, upon full payment in cash to the Company of the
Exercise Price of the Shares as to which the Option shall be exercised and upon
receipt of a duly executed shareholders agreement (in the form attached hereto
as Exhibit A or in such other form as the Company may reasonably require), issue
to the Optionee the Shares subject to the Option. Any issuance of Shares to an
Optionee pursuant to the preceding sentence shall be made by the Company within
90 days after the date of exercise. For purposes of this Agreement, the fair
market value of Shares shall be determined by such methods or procedures as
shall be established from time to time by the Board acting in its sole
discretion and in good faith. In making such determinations, the Board may rely
on a valuation report by an investment banking or valuation firm selected by the
Board. The Committee established by the Board to administer the Plan (the
"Committee") may, in its sole discretion, permit the Optionee to pay the
Exercise Price in previously acquired Shares rather than in cash.

                  (d)      Exercise Upon Death or Termination of Employment.

                           (i)      If the Optionee dies while an employee of
the Company, the Optionee's Designee may exercise the Option, to the extent it
was vested on the date of termination, by giving the Company written notice of
such exercise within 12 months after the date of Optionee's death, but in no
event later than the Expiration Date. An Optionee's "Designee" means the person
designated by the Optionee in his or her most recently filed beneficiary
designation filed with the Company to receive the Optionee's rights under the
Plan upon the Optionee's death, or if there is no such designation or no such
designated person survives the Optionee, by the person or persons to whom the
Optionee's rights pass by will or applicable law, or if no such person has such
right, by his executors or administrators.

                           (ii)     If the Company shall terminate Optionee's
employment with the Company because of disability, the Optionee may exercise the
Option to the extent it was vested on the date of termination, by giving the
Company written notice of such exercise within 12


                                       6
<PAGE>   55

months after the date of termination of employment, but in no event later than
the Expiration Date.

                           (iii)    If the Optionee terminates his employment
with the Company other than for Good Reason, the Optionee may exercise the
Option to the extent it was vested on the date of termination, by giving the
Company written notice of such exercise within 90 days after the date of
termination of employment, but in no event later then the Expiration Date. For
purposes of this Agreement, "Good Reason" has the meaning set forth in the
executive severance or employment agreement, if any, then in effect between the
Company and the Optionee or, in the absence of such agreement shall mean, if the
basis for such Good Reason is not cured within a reasonable period of time
(determined in light of the cure appropriate to the basis of such Good Reason,
but in no event less than 15 days), the failure of the Company to pay any
undisputed amount due to the Optionee in connection with his employment by the
Company.

                           (iv)     If the Optionee's employment shall terminate
for any reason other than death, disability or Cause (as hereinafter defined),
or if the Optionee shall terminate his employment with the Company for Good
Reason, the Optionee may exercise the Option to the extent it was vested on the
date of termination or, otherwise would have vested in the 12 months thereafter,
in either event according to the applicable vesting schedule in Section 2(c)(i),
by giving the Company written notice of such exercise within 18 months after the
date of termination of employment, but in no event later than the Expiration
Date. Notwithstanding the foregoing, the Optionee shall forfeit his right to
exercise any Options that would have vested within the 12 months after
termination, if the Optionee violates the terms regarding non-competition set
forth in the Optionee's executive severance or employment agreement.

                           (v)      If the Optionee's employment shall terminate
for Cause, all right to exercise the Option shall terminate at the date of such
termination of employment. For purposes of this Agreement, "Cause" has the
meaning set forth in the executive severance or employment agreement, if any,
then in effect between the Company and the Optionee or, in the absence of such
agreement, shall mean (i) the Optionee's conviction of, or plea of guilty or
nolo contendere to, a felony, (ii) the Optionee's gross negligence in the
performance of his duties and obligations to the Company, which is not corrected
within 15 business days after written notice, (iii) the Optionee's knowingly
dishonest act, or knowing bad faith or willful misconduct in the performance of
his duties and obligations to the Company to the material detriment of the
Company, which is not corrected within 15 business days after written notice, or
(iv) the Optionee's other material breach of his obligations under this
Agreement, which is not corrected within a reasonable period of time (determined
in light of the cure appropriate to such material breach, but in no event less
than 15 business days) after written notice.

                           (vi)     In the event of termination of employment,
if an Incentive Stock Option is exercised after the expiration of the exercise
periods that apply for purpose of Section 422 of the Code, such stock option
shall thereafter be treated as a nonqualified stock option.

                  (e)      Transferability. Except as otherwise provided in this
Section, the Option is not transferable other than as designated by the Optionee
in his or her most recently filed Beneficiary


                                       7
<PAGE>   56

designation filed with the Company, or if there is no such designation or no
such designated person survives the Optionee, as designated by the Optionee, by
will or by the laws of descent and distribution, and during the Optionee's life,
may be exercised only by the Optionee. However, an Optionee, with the approval
of the Committee, may transfer the Option for no consideration to or for the
benefit of the Optionee's Immediate Family or to a partnership or limited
liability company for one or more members of the Optionee's Immediate Family,
subject to such limits as the Committee may establish, and the transferee shall
remain subject to all the terms and conditions applicable to Options prior to
such transfer. The foregoing right to transfer the Option shall apply to the
right to consent to amendments to this Agreement and, in the discretion of the
Committee, shall also apply to the right to transfer ancillary rights associated
with the Option. The term "Immediate Family" shall mean the Optionee's spouse,
parents, children, stepchildren, adoptive relationships, sisters, brothers,
nieces, nephews and grandchildren (and, for this purpose, shall also include the
Optionee).

                  (f)      Adjustments. In the event of any change in corporate
capitalization (including, but not limited to, a change in the number of shares
of Common Stock outstanding), such as a stock split or a corporate transaction,
such as any merger, consolidation, separation, including a spin-off, or other
distribution of stock or property of the Company, any reorganization (whether or
not such reorganization comes within the definition of such term in Section 368
of the Code) or any partial or complete liquidation of the Company, the
Committee or Board may make such substitution or adjustments in the number, kind
and option price of shares subject to the Option and/or such other equitable
substitution or adjustments as it may determine to be appropriate in its sole
discretion; provided, however, that the number of shares subject to the Option
shall always be a whole number. In the event of a corporate merger,
consolidation, acquisition of property or stock, separation, reorganization or
liquidation, the Board shall be authorized to cause the Company to issue or
assume stock options, whether or not in transaction to which Section 424(a) of
the Code applies, by means of substitution of new stock options for previously
issued stock options or an assumption of previously issued stock options.

                  (g)      No Rights as Stockholder. The Optionee shall have no
rights as a stockholder with respect to any Shares subject to the Option prior
to the date of issuance to the Optionee of a certificate or certificates for
such Shares.

                  (h)      Optionee Acknowledgement. The Optionee acknowledges
that:

                           (i)      the future value of the Company is highly
speculative;

                           (ii)     the Optionee is not relying on the value of
this Option as current compensation;

                           (iii)    the Company has no obligation to the
Optionee to sell the Company or to sell Shares publicly (which may have the
effect of reducing the value of the Company);


                                       8
<PAGE>   57

                           (iv)     upon exercise of this Option, unless the
Shares issuable upon exercise of the Options have been registered under
applicable securities laws, there will be substantial restrictions on the
transferability of the Shares; and

                           (v)      the past performance or experience of the
Company, the Company's officers, directors, agents, or employees, will not in
any way indicate or predict the results of the ownership of Shares or of the
Company's activities.

                  (i)      No Right to Continued Employment. The Option shall
not confer upon the Optionee any right with respect to continuance of employment
by the Company, nor shall it interfere in any way with the right of the
Optionee's employer to terminate the Optionee's employment at any time.

                  (j)      Compliance With Law and Regulations. The Option
herein granted and the obligation of the Company to sell and deliver shares
hereunder, shall be subject to all applicable Federal and State laws, rules and
regulations and to such approvals by any government or regulatory agency as may
be required. The Company shall not be required to issue or deliver any
certificates for Shares prior to (i) the listing of such Shares on any stock
exchange or national market quotations system on which the Shares may then be
listed and (ii) the completion of any registration or qualification of such
Shares under any Federal or State law, or any rule or regulation of any
government body which the Company shall, in its sole discretion, determine to be
necessary or advisable. Moreover, the Option herein granted may not be exercised
if its exercise, or the receipt of Shares pursuant hereto, would be contrary to
applicable law.

3.       Optionee Bound by Plan.

         The Optionee hereby acknowledges receipt of a copy of the Plan and
agrees to be bound by all the terms and provisions thereof.

4.       Notices.

principles.
