         of the restrictions, the Committee shall have the right and authority
         to cancel such number of Shares as is necessary so that the
         compensation amount attributable to the remaining Shares that will
         become unrestricted on or before the next immediate May 31 will be
         deductible by the Company after taking into account Section 162(m) of
         the Internal Revenue Code, and the employee shall automatically receive
         as a credit to his Company Contribution Account under the RPM, Inc.
         Deferred Compensation Plan ("Deferred Compensation Plan") an amount
         equal to (i) multiplied by (ii) where:

                  (i)  equals the average closing price of one Share for the

         not later than ten (10) days prior to the date the restrictions for
         such Shares lapse pursuant to Section 5.2 above. The Employee shall be
         notified in writing of any such cancellation and shall be subject to
         such further requirements as determined by the Committee in its sole
         discretion.

                  11.2. In the event that an employee who becomes an eligible

<PAGE>

         Section 162(m) of the Internal Revenue Code upon lapse of the
         restrictions, the Committee shall have the right and authority to
         cancel such number of Shares as is necessary so that the compensation
         amount attributable to the remaining Shares that will become
         unrestricted on or before the next immediate May 31 will be deductible
         by the Company after taking into account Section 162(m) of the
         Internal Revenue Code, and the employee shall automatically have the
         same number of Shares credited to his Restricted Stock Account under
         the Deferred Compensation Plan. The Committee may determine to make
         such a cancellation at any time but not later than ten (10) days prior
         to the date the restrictions for such Shares lapse pursuant to Section
         5.2 above. The Employee shall be notified in writing of any such
         cancellation and shall be subject to such further requirements as
         determined by the Committee in its sole discretion.

                  11.3. In the event that any employee has received an award of
         Shares subject to the restrictions set forth in Section 5.2 above, has
         not made an election under Section 83(b) of the Internal Revenue Code,
         and will be in receipt of an amount of compensation upon lapse of such
         restrictions, the employee may elect to surrender, as of a date
         specified in his election, any of the Shares awarded under this Plan
         and the employee shall automatically have the same number of Shares
         credited to his Restricted Stock Account under the Deferred
         Compensation Plan. For an election to be valid, it must be made in
         accordance with the terms and conditions imposed by the Committee and
         the requirements of the Deferred Compensation Plan. An employee may
         make one (1) irrevocable election during each Plan Year. The first
         surrender election of an employee must be delivered to

<PAGE>

         and accepted by the Committee in accordance with the deadlines
         established by the Committee. For each succeeding Plan Year, the
         surrender election with respect to the Shares must be delivered to and
         accepted by the Committee at least six (6) months prior to the date
         all restrictions with respect to the Shares lapse.

                  11.4 An employee shall be vested in Shares or amounts credited
         to his Account Balance under the Deferred Compensation Plan as a result
         of cancellation or surrender of Shares under this Plan when
         restrictions on the Shares cancelled or surrendered would have lapsed
         under this Plan."

         IN WITNESS WHEREOF, RPM, Inc., by its officer as duly authorized, has
caused this Second Amendment to the Plan to be executed as of this 22nd day of
May, 2002.

Dear Mark,

         This letter is pursuant to your conversation with Ron Stanton and
myself today regarding the termination of your employment, effective August 31,
2002.

         You will receive payment for all wages earned through August 31, 2002,
in your paycheck issued on August 31, 2002. In addition, if you choose to sign
and return the Release and Settlement Agreement within the specified timeframe
and if you have complied with the terms of said Agreement, you will receive one
payment equal to one week of your base compensation. The specific dollar amount
of this severance is outlined in the Release and Settlement Agreement. Any
severance paid to you would be subject to state and federal taxes. The original
Release and Settlement Agreement should be returned to my attention on or before
the specified date outlined in said Agreement.

         All benefits you participated in through LipoScience terminate at
midnight on August 31, 2002. As discussed in our conversation on August 7, 2002,
you have received paperwork pertaining to your health insurance benefits that
requires your attention. Please read this information over carefully. With
respect to COBRA coverage, completed and signed documents should be returned to
my attention whether or not you elect COBRA coverage. If you elect COBRA,
LipoScience will pay the premiums for you until you find other employment
pursuant to the terms of the employment letter dated September 4, 2001, between
LipoScience and you ("Agreement"). I would be happy to discuss these details
with you at any time.

         Under the conditions of the Agreement, you will receive nine severance
payments equal to one month of your August 31, 2002 base compensation each to be
paid out on September 30/th/, October 31/st/, November 30/th/, December 31/st/
of 2002 and January 31/st/, February 28/th/, March 31/st/, April 30/th/, May
31/st/ of 2003. Any severance paid to you would be subject to state and federal
taxes. The severance checks will be forwarded to you via regular mail.

         You will receive payment for two weeks of vacation based on your August
31, 2002 base compensation.

         The employment letter agreement also provides that until you obtain
other employment (i) and if you choose to convert your life insurance policies,
LipoScience will pay your premiums; and (ii) you will continue to receive a
$1,000 per month auto allowance, net of applicable taxes; and (iii) you are
eligible to receive up to $10,000 reimbursement for estate/financial planning
expenses incurred and paid by you in 2002.

         As you are aware, as a condition of employment with LipoScience, you

receipts to Ron Stanton by August 31, 2002, in order for you to receive
reimbursement for these expenses.

         It is important for you to cease calling on customers and to inform Ron
Stanton of any upcoming programs, lunches, etc. that you had scheduled.
