                       OTHER SENIOR MANAGEMENT AGREEMENT
                       ---------------------------------

          THIS AGREEMENT is made as of March 28, 1997, between Select Medical
Corporation, a Delaware corporation (the "Company"), and Michael E. Tarvin (the
"Executive").

          The Company and Executive desire to enter into an agreement pursuant
to which Executive will purchase, and the Company will sell, (i) 46,150 shares
of Common Stock, 41,150 shares of which shall constitute the "Executive Stock"
and 5,000 shares of which shall constitute the "Investor Common Stock" and (ii)
23.75 shares of Class A Preferred.  Certain definitions are set forth in Section
13 of this Agreement.

          Golder, Thoma, Cressey, Rauner Fund V, L.P. ("GTCR") and Welsh,
Carson, Anderson & Stowe VII, L.P. and certain of its partners ("WCAS")
purchased shares of Common Stock and may purchase additional shares of Common
Stock and shares of Class A Preferred, pursuant to a purchase agreement among
the Company and the Purchasers, dated as of February 5, 1997 (as amended and
supplemented from time to time, the "Purchase Agreement"), GTCR and WCAS are
collectively referred to herein as the "Purchasers" and individually as a
"Purchaser." Certain provisions of this Agreement are intended for the benefit
of, and will be enforceable by, the Purchasers.

          The parties hereto agree as follows:

                         PROVISIONS RELATING TO STOCK

          1.   Purchase and Sale of Stock.
               --------------------------

          (a)(i)  Upon execution of this Agreement, Executive will purchase, and
the Company will sell, 41,150 shares of Executive Stock at a price of $0.25 per
share.  The Company will deliver to the Executive the certificate representing
such Executive Stock, and the Executive will deliver to the Company a cashier's
or certified check or wire transfer of funds in the aggregate amount of
$10,287.50.

          (a)(ii) Upon execution of this Agreement, Executive will purchase, and
the Company will sell, 3,635 shares of Investor Common Stock at a price of $0.25
per share. The Company will deliver to the Executive the certificate
representing such Investor Common Stock, and the Executive will deliver to the
Company a cashier's or certified check or wire transfer of funds in the
aggregate amount of $908.75.

          (b)     Upon the purchase from time to time by the Purchasers (a
"Purchaser Closing") of additional shares of Common Stock and Class A Preferred
pursuant to Section 1B(c) of the Purchase Agreement, Executive will purchase,
and the Company will sell (i) up to an additional 1,365 shares of Investor
Common Stock at a price of $0.25 per share and (ii) up to an aggregate of 23.75
shares of Class A Preferred at a price of $ 1,000.00 per share (each of (i) and
(ii) immediately above as adjusted from time to time as a result of stock
dividends, stock splits, recapitalization and similar events). The number of
shares of Investor Common Stock and Class A Preferred to be sold by the Company
and purchased by the Executive at any Purchaser Closing shall equal 1,365 shares
of Investor Common Stock or 23.75 shares of Class A Preferred

<PAGE>

(each as adjusted from time to time as a result of stock dividends, stock
splits, recapitalization and similar events), multiplied by (ii) a fraction (A)
                                              -------------
the numerator of which will be the aggregate number of shares of such class of
stock to be concurrently purchased by the Purchasers and (B) the denominator of
which will be 2,732,480 shares, in the case of Investor Common Stock and 47,500
shares, in the case of Class A Preferred (each as adjusted from time to time as
a result of stock dividends, stock splits, recapitalization and similar events).
The Company will deliver to Executive the certificates representing such shares
of Investor Stock purchased by the Executive, and Executive will deliver to the
Company a cashier's or certified check or a wire transfer of funds in the
aggregate amount of the price per share of such Investor Stock multiplied by the
                                                               -------------
number of shares so purchased by the Executive.

          (c)  Within 30 days after Executive purchases any Stock from the
Company, Executive will make an effective election with the Internal Revenue
Service under Section 83(b) of the Internal Revenue Code and the regulations
promulgated thereunder in the form of Exhibit A attached hereto.
                                      ---------

          (d)  Executive's commitment to purchase shares of Investor Stock
pursuant to this Agreement shall terminate upon a Qualified Public Offering.

          (e)  In connection with the purchase and sale of the Stock hereunder,
Executive represents and warrants to the Company that:

               (i)   The Stock to be acquired by Executive pursuant to this
     Agreement will be acquired for Executive's own account and not with a view
     to, or intention of, distribution thereof in violation of the Securities
     Act, or any applicable state securities laws, and the Stock will not be
     disposed of in contravention of the Securities Act or any applicable state
     securities laws.

               (ii)  Executive is an executive office of the Company, is
     sophisticated in financial matters and is able to evaluate the risks and
     benefits of the investment in the Stock.

               (iii) Executive is able to bear the economic risk of his
     investment in the Stock for an indefinite period of time because the Stock
     has not been registered under the Securities Act and, therefore, cannot be
     sold unless subsequently registered under the Securities Act or an
     exemption from such registration is available.

               (iv)  Executive has had an opportunity to ask questions and
     receive answers concerning the terms and conditions of the offering of
     Stock and has had full access to such other information concerning the
     Company as he has requested.

               (v)   This Agreement constitutes the legal, valid and binding
     obligation of Executive, enforceable in accordance with its terms, and the
     execution, delivery and performance of this Agreement by Executive does not
     and will not conflict with, violate or cause a breach of any agreement,
     contract or instrument to which Executive is a party or any judgment, order
     or decree to which Executive is subject.

               (vi)  Executive is a resident of the State of Pennsylvania.

                                      -2-
<PAGE>

          (f)  As an inducement to the Company to issue the Stock to Executive,
as a condition thereto, Executive acknowledges and agrees that:

               (i)  neither the issuance of the Stock to Executive nor any
     provision contained herein shall entitle Executive to remain in the
     employment of the Company and its Subsidiaries or affect the right of the
     Company to terminate Executive's employment at any time for any reason; and

               (ii) the Company shall have no duty or obligation to disclose to
     Executive, and Executive shall have no right to be advised of, any material
     information regarding the Company and its Subsidiaries at any time prior
     to, upon or in connection with the repurchase of Stock upon the termination
     of Executive's employment with the Company and its Subsidiaries.

          2.   Vesting of Executive Stock.
               --------------------------

          (a)  Except as otherwise provided in Section 2(b) below, the Executive
Stock will become vested in accordance with the following schedule, if as of
each such date Executive is still employed by the Company or any of its
Subsidiaries:

                                             Cumulative
                                      Percentage of Executive
          Anniversary Date                  Stock Vested
          ----------------          ----------------------------

           March 1, 1998                       20%

           March 1, 1999                       40%

           March 1, 2000                       60%

           March 1, 2001                       80%

           March 1, 2002                      100%

          (b)  If Executive ceases to be employed by the Company and its
Subsidiaries on any date other than any anniversary date prior to March 1, 2002,
the cumulative percentage of Executive Stock to become vested will be determined
on a pro rata basis according to the number of days elapsed since the prior
anniversary date.  Upon the occurrence of a Sale of the Company (while Executive
is employed by the Company), all shares of Executive Stock which have not yet
become vested shall become vested at the time of such event.  Shares of
Executive Stock which have become vested are referred to herein as "Vested
Shares," and all other shares of Executive Stock are referred to herein as
"Unvested Shares."

          3.   Repurchase Option.
               -----------------

          (a)(i) In the event Executive ceases to be employed by the Company and
its Subsidiaries for any reason (the "Termination"), the Executive Stock and the
Investor Stock (in each case, whether held by Executive or one or more of
Executive's transferees, other than the

                                      -3-
<PAGE>

Company or the Purchasers) will be subject to repurchase, in each case by the
Company and the Purchasers pursuant to the terms and conditions set forth in
this Section 3; provided, however, that if Executive has purchased or, at
                --------  -------
Executive's option, purchases all of the shares of Investor Stock that Executive
has committed to purchase under Section 1(b) above at the time of Termination,
then the Investor Stock will not be subject to repurchase pursuant to this
Section 3(a)(i); provided, further, that if the Investor Stock is subject to
                 --------  -------
repurchase pursuant to this Section 3(a)(i) and the Repurchase Option has been
consummated pursuant to this Section 3, then Executive's commitment to purchase
additional shares of Investor Stock pursuant to Section 1(b) above shall
terminate upon the consummation of the Repurchase Option.

          (a)(ii) In the event Executive fails to purchase any shares of the
Investor Stock which he is required to purchase pursuant to this Agreement (a
"Triggering Event"), the Executive Stock and the Investor Stock (in each case,
whether held by Executive or one or more of Executive's transferees, other than
the Company or the Purchasers) will be subject to repurchase, in each case by
the Company and the Purchasers pursuant to the terms and conditions set forth in
this Section 3.  The repurchase options set forth in Sections 3(a)(i) and
3(a)(ii) shall be referred to herein as the "Repurchase Option".

          (b)     In the event of Termination, (i) the purchase price for each
Unvested Share of Executive Stock will be Executive's Original Cost for such
share, (ii) the purchase price for each Vested Share of Executive Stock and each
share of Investor Common Stock will be the Fair Market Value for such share and
(iii) the purchase price for each share of Class A Preferred will be the
Liquidation Value (as defined in the Company's Restated Certificate of
Incorporation) of such share, plus all accrued and unpaid dividends thereon;
provided, however, that if Executive's employment is terminated with Cause, the
--------  -------
purchase price for each Vested Share of Executive Stock will be Executive's
Original Cost for such share.  Upon a Triggering Event (even if there is also a
Termination), (i) the purchase price for each share of Executive Stock (whether
a Vested Share or an Unvested Share) and each share of Investor Common Stock
will be Executive's Original Cost for such share and (ii) the purchase price for
each share of Class A Preferred will be the Liquidation Value of such share,
plus all accrued and unpaid dividends thereon.

          (c)     The Board may elect to purchase all or any portion of any
class of the Executive Stock or the Investor Stock by delivering written notice
(the "Repurchase Notice") to the holder or holders of such Stock within one year
after the Termination or Triggering Event. The Repurchase Notice will set forth
the number of shares of Stock (including the number of Unvested Shares and
Vested Shares, if any) of each class to be acquired from each holder, the
aggregate consideration to be paid for such shares and the time and place for
the closing of the transaction. The number of shares to be repurchased by the
Company shall first be satisfied to the extent possible from the shares of Stock
held by Executive at the time of delivery of the Repurchase Notice. If the
number of shares of Stock then held by Executive is less than the total number
of shares of Stock which the Company has elected to purchase, the Company shall
purchase the remaining shares elected to be purchased from the other holder(s)
of Stock under this Agreement, pro rata according to the number of shares of
Stock held by such other holder(s) at the time of delivery of such Repurchase
Notice (determined as nearly as practicable to the nearest share). The number of
shares of each class of Stock to be repurchased hereunder will be

                                      -4-
<PAGE>

allocated among Executive and the other holders of Stock (if any) pro rata
according to the number of shares of Stock to be purchased from such person.

          (d)  If for any reason the Company does not elect to purchase all of
the Stock pursuant to the Repurchase Option, the Purchasers shall be entitled to
exercise the Repurchase Option for the shares of Stock the Company has not
elected to purchase (the "Available Shares").  As soon as practicable after the
Company has determined that there will be Available Shares, but in any event
within ten months after the Termination or Triggering Event, the Company shall
give written notice (the "Option Notice") to the Purchasers setting forth the
number of Available Shares and the purchase price for the Available Shares.  The
Purchasers may elect to purchase any or all of the Available Shares by giving
written notice to the Company within one month after the Option Notice has been
given by the Company.  As soon as practicable, and in any event within ten days,
after the expiration of the one-month period set forth above, the Company shall
notify each holder of Stock as to the number of shares being purchased from such
holder by the Purchasers (the "Supplemental Repurchase Notice").  If the
Purchasers elect to purchase an aggregate number of shares greater than the
Available Shares, the Available Shares will be allocated among the Purchasers
based upon the number of shares of Common Stock held by such Purchaser on a
fully-diluted basis.  At the time the Company delivers the Supplemental
Repurchase Notice to the holder(s) of such Stock, the Company shall also deliver
written notice to each Purchaser setting forth the number of shares such
Purchaser is entitled to purchase, the aggregate purchase price and the time and
place of the closing of the transaction.  The number of shares of each class of
Stock to be repurchased hereunder shall be allocated among the Company and each
Purchaser pro rata according to the number of shares of Stock to be purchased by
each of them.

          (e)  The closing of the purchase of the Stock pursuant to the
Repurchase Option shall take place on the date designated by the Company in the
Repurchase Notice or Supplemental Repurchase Notice, which date shall not be
more than one month nor less than five days after the delivery of the later of
either such notice to be delivered. The Company and/or the Purchasers will pay
for the Stock to be purchased pursuant to the Repurchase Option by delivery of a
check or wire transfer of funds in the aggregate amount of the purchase price
for such shares. In addition, the Company may pay the purchase price for such
shares by offsetting amounts outstanding under any bona fide debts owed by
Executive to the Company. The Company and the Purchasers will be entitled to
receive customary representations and warranties from the sellers regarding such
sale and to require all sellers' signatures be guaranteed.

          (f)  Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Stock by the Company shall be subject to
applicable restrictions contained in the Delaware General Corporation Law and in
the Company's and its Subsidiaries' debt and equity financing agreements.  If
any such restrictions prohibit the repurchase of Stock hereunder which the
Company is otherwise entitled or required to make, the Company may make such
repurchases as soon as it is permitted to do so under such restrictions.

          (g)  Upon the occurrence of a Qualified Public Offering, the
Repurchase Option shall terminate with respect to Vested Shares of Executive
Stock and all shares of Investor Stock.

                                      -5-

          4.   Restrictions on Transfer of Stock.
               ---------------------------------

          (a)  Retention of Executive Stock.  Until the fifth anniversary of the
               ----------------------------
date of this Agreement, Executive shall not sell, transfer, assign, pledge or
otherwise dispose of any interest in any shares of Executive Stock, except for
Exempt Transfers (as defined in Section 4(b) below) other than sales to the
public pursuant to Rule 144 promulgated under the Securities Act or any similar
rule then in force.

          (b)  Transfer of Stock. Subject to Section 4(a) above, Executive shall
               -----------------
not Transfer any interest in any shares of Stock, except pursuant to (i) the
provisions of Section 3 hereof, a Public Sale or a Sale of the Company ("Exempt
Transfers") or (ii) the provisions of this Section 4; provided that in no event
shall any Transfer of Stock pursuant to this Section 4 be made for any
consideration other than cash payable upon consummation of such Transfer or in
installments over time.  Prior to making any Transfer other than an Exempt
Transfer, Executive will give written notice (the "Sale Notice") to the Company
and the Purchasers.  The Sale Notice will disclose in reasonable detail the
identity of the prospective transferee(s), the number of shares to be
transferred and the terms and conditions of the proposed transfer.  Executive
will not consummate any Transfer until 110 days after the Sale Notice has been
given to the Company and to the Purchasers, unless the parties to the Transfer
have been finally determined pursuant to this Section 4 prior to the expiration
of such 110-day period. (The date of the first to occur of such events is
referred to herein as the "Authorization Date").

          (c)  First Refusal Rights. The Company may elect to purchase all (but
               --------------------
not less than all) of the shares of Stock to be transferred upon the same terms
and conditions as those set forth in the Sale Notice by delivering a written
notice of such election to Executive and the Purchasers within 60 days after the
Sale Notice has been given to the Company.  If the Company has not elected to
purchase all of the Stock to be transferred, the Purchasers may elect to
purchase all (but not less than all) of the Stock to be transferred upon the
same terms and conditions as those set forth in the Sale Notice by giving
written notice of such election to Executive within 90 days after the Sale
Notice has been given to the Purchasers.  If the Purchasers elect to purchase an
aggregate number of shares greater than the Stock to be transferred, such Stock
will be allocated among the Purchasers based upon the number of shares of Stock
held by such Purchaser on a fully-diluted basis.  If neither the Company nor the
Purchasers elect to purchase all of the shares of Stock specified in the Sale
Notice, Executive may transfer the shares of Stock specified in the Sale Notice,
subject to the provisions of Section 4(d) below, at a price and on terms no more
favorable to the transferee(s) thereof than specified in the Sale Notice during
the 60-day period immediately following the Authorization Date.  Any shares of
Stock not transferred within such 60-day period will be subject to the
provisions of this Section 4(c) upon subsequent transfer.  The Company may pay
the purchase price for such shares by offsetting amounts outstanding under any
bona fide debts owed by Executive to the Company.

          (d)  Purchaser Participation Rights.
               ------------------------------

               (i) if neither the Company nor the Purchasers has elected to
     purchase all of the Stock specified in the Sale Notice pursuant to Section
     4(c) above, the Purchasers may elect to participate in the contemplated
     Transfer by delivering written

                                      -6-
<PAGE>

     notice to Executive and the Company within 100 days after receipt by the
     Purchasers of the Sale Notice. If the Purchasers have elected to
     participate in such sale, Executive and the Purchasers will be entitled to
     sell in the contemplated sale, at the same price and on the same terms, a
     number of shares of the Company's Common Stock equal to the product of (i)
     the quotient determined by dividing the percentage of the Company's Common
     Stock (on a fully-diluted basis) held by such person, by the aggregate
     percentage of the Company's Common Stock (on a fully-diluted basis) owned
     by Executive (including both Vested and Unvested Shares) and each Purchaser
     participating in such sale and (ii) the number of shares of Common Stock to
     be sold in the contemplated sale. Any purchaser in a sale subject to this
     Section 4(d) will be required to purchase from the Purchasers, at each
     Purchaser's election, a portion of the Class A Preferred held by such
     Purchasers equal to the greater of the percentage of (x) such Purchaser's
     Common Stock being sold in such transaction and (y) the Executive's Class A
     Preferred, as the case may be, being sold in such transaction.

     For example, if:
                  --

          (1)  the Sale Notice contemplated a sale of 100 shares of Common
     Stock;

          (2)  Executive was at such time the owner of 120 shares of Common
     Stock (which was equal to 30% of the Common Stock on a fully-diluted
     basis); and

          (3)  each Purchaser elected to participate and each Purchaser owned 40
     shares of Common Stock (which was equal to 10% of Common Stock on a fully-
     diluted basis) and 120 shares of Class A Preferred;

          then
          ----

          (A)  Executive would be entitled to sell 60 shares of Common Stock
     (30% / 50% x 100 shares); and

          (B)  each Purchaser would be entitled to sell 20 shares of Common
     Stock (10% / 50% x 100 shares) and 60 shares of Class A Preferred (the same
     percentage of the Purchaser's Class A Preferred as the percentage of the
     Purchaser's Common Stock being sold, i.e., 50%).

time to time may, in its sole discretion, increase the Annual Base Salary.  The

to the Company's requirements with respect to reporting and documentation of
such expenses.

          (c)  Termination.

     judgment) or death or until the Board determines in its good faith judgment

     Company.

               (ii) Upon a termination of the Employment Period for any reason,

          9.   Confidential Information.  Executive acknowledges that the
               ------------------------
information, observations and data obtained by him during the course of his
performance under this Agreement concerning the business and affairs of the
Company and its affiliates are the property of the Company.  Therefore,
Executive agrees that he will not disclose to any unauthorized person or use for
his own account any of such information, observations or data without the
Board's written consent, unless and to the extent that the aforementioned
matters become generally known to and available for use by the public other than
as a result of Executive's acts or omissions to act.  Executive agrees to
deliver to the Company at the termination of his employment, or at any other
time the Company may request in writing, all memoranda, notes, plans, records,
reports and other documents (and copies thereof) relating to the business of the
Company and its affiliates (including, without limitation, all acquisition
prospects, lists and contact information) which he may then possess or have
under his control.

          10.  Nonsolicitation.  During the two years following the date of
               ---------------
termination of Executive's employment, Executive shall not directly or
indirectly through another entity (i) induce or attempt to induce any employee
of the Company or any Subsidiary to leave the employ of the Company or such
Subsidiary, or in any way interfere with the relationship between the Company or
any Subsidiary and any employee thereof, (ii) hire any person who was an
employee of the Company or any Subsidiary on the date of termination of
Executive's employment, or (iii) induce or attempt to induce any customer,
supplier, licensee or other business relation of the Company or any Subsidiary
to cease doing business with the Company or such Subsidiary, or in any way
interfere with the relationship between any such customer, supplier, licensee or
business relation and the Company or any Subsidiary.

          11.  Enforcement.  If, at the time of enforcement of Section 9 or 10
               -----------
of this Agreement, a court holds that the restrictions stated herein are
unreasonable under circumstances then existing, the parties hereto agree that
the maximum duration, scope or geographical area reasonable under such
circumstances shall be substituted for the stated period, scope or area and that
the court shall be allowed to revise the restrictions contained herein to cover
the maximum duration, scope and area permitted by law.  Because Executive's
services are unique and because Executive has access to confidential
information, the parties hereto agree that money damages would be an inadequate
remedy for any breach of this Agreement.  Therefore, in the event a breach or
threatened breach of this Agreement, the Company or its successors or assigns
may, in addition to other rights and remedies existing in their favor, apply to
any court of competent jurisdiction for specific performance and/or injunctive
or other relief in order to enforce, or prevent any violations of, the
provisions hereof (without posting a bond or other security).

          12.  Submission to Jurisdiction.  Each of the parties (i) submits to
               --------------------------
the jurisdiction of any state or federal court sitting in Chicago, Illinois in
any action or proceeding arising out of or relating to this Agreement (including
Sections 9 and 10), (ii) agrees that all claims in respect of such action or
proceeding may be heard or determined in any such court and (iii) agrees not to
bring any action or proceeding arising out of or relating to this Agreement in
any other court.  Each of the parties waives any defense of inconvenient forum
to the maintenance of any action or proceeding so brought and waives any bond,
surety or other security that might be required of any other party with respect
thereto.  Each party agrees that a final judgment in any action or proceeding so
brought shall be conclusive and may be enforced by suit on the judgment or in
any other manner provided by law.

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

          (a)  Expenses.  The Executive will bear his own costs and expenses
               --------
(including legal expenses) incurred in connection with the negotiation and
execution of this Agreement and the consummation of the transactions
contemplated by this Agreement.

          (b)  Transfers in Violation of Agreement.  Any Transfer or attempted
               -----------------------------------
Transfer of any Stock in violation of any provision of this Agreement shall be
void, and the Company shall not record such Transfer on its books or treat any
purported transferee of such Stock as the owner of such stock for any purpose.

          (c)  Severability. Whenever possible, each provision of this Agreement
               ------------
will be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

          (d)  Complete Agreement.  This Agreement, those documents expressly
               ------------------
referred to herein and other documents of even date herewith embody the complete
agreement and understanding among the parties and supersede and preempt any
prior understandings, agreements or representations by or among the parties,
written or oral, which may have related to the subject matter hereof in any way.

          (e)  Counterparts.  This Agreement may be executed in separate
               ------------
counterparts (including by means of telecopied signature pages), each of which
is deemed to be an original and all of which taken together constitute one and
the same agreement.

          (f)  Successors and Assigns. Except as otherwise provided herein, this
               ----------------------
Agreement shall bind and inure to the benefit of and be enforceable by
Executive, the Company, the Purchasers and their respective successors and
assigns (including subsequent holders of Stock); provided that the rights and
obligations of Executive under this Agreement shall not be assignable except in
connection with a permitted Transfer of Stock hereunder.

          (g)  Choice of Law.  The corporate law of the State of Delaware will
               -------------
govern all questions concerning the relative rights of the Company and its
stockholders. All other questions concerning the construction, validity and
interpretation of this Agreement and the exhibits hereto will be governed by and
construed in accordance with the internal laws of the State of Illinois, without
giving effect to any choice of law or conflict of law provision or rule (whether
of the State of Illinois or any other jurisdiction) that would cause the
application of the laws of any jurisdiction other than the State of Illinois.

                                      -16-

          (h)  Remedies.  Each of the parties to this Agreement (including the
               --------
Purchasers) will be entitled to enforce its rights under this Agreement
specifically, to recover damages and costs (including attorneys' fees) caused by
any breach of any provision of this Agreement and to exercise all other rights
existing in its favor.  The parties hereto agree and acknowledge that money
damages may not be an adequate remedy for any breach of the provisions of this
Agreement and that any party may in its sole discretion apply to any court of
law or equity of competent jurisdiction (without posting any bond or deposit)
for specific performance and/or other injunctive relief in order to enforce or
prevent any violations of the provisions of this Agreement.

          (i)  Amendment and Waiver.  The provisions of this Agreement may be
               --------------------
amended and waived only with the prior written consent of the Company, Executive
and each of the Purchasers.

          (j)  Business Days.  If any time period for giving notice or taking
               -------------
action hereunder expires on a day which is a Saturday, Sunday or holiday in the
state in which the Company's chief executive office is located, the time period
shall be automatically extended to the business day immediately following such
Saturday, Sunday or holiday.

          (k)  Termination. This Agreement (except for the provisions of Section
               -----------
8) shall survive the termination of Executive's employment with the Company and
shall remain in full force and effect after such termination.
