CONFIDENTIALITY AND POST-EMPLOYMENT ACTIVITIES AGREEMENT

A. I, Jerry E. Sheridan, have been hired as Vice President, Finance and Chief Financial Officer of
AmeriGas Propane, Inc., a Pennsylvania corporation, which is the general partner of AmeriGas
Partners, L.P. and AmeriGas Propane, L.P. As such, I will have responsibility for the finance,
accounting and management information systems (“MIS”) functions of the propane supply, distribution
and sale and other businesses of AmeriGas Partners, L.P., and its subsidiaries, partnerships and
affiliates (collectively “AmeriGas”) throughout the United States and such U.S. territories and/or
foreign nations in which AmeriGas may decide to do business. During the course of my employment,
AmeriGas will put tremendous trust and confidence in me by placing me in charge of the finance,
accounting and MIS functions and by disclosing to me, as well as having me develop confidential
information about its business, finances, and customers.

B. I am also a member of AmeriGas’s Senior Management Team. The Senior Management Team is made up
of a select group of senior officers of AmeriGas, who are responsible for developing the strategic
plans of AmeriGas, including any crucial changes to be made in the management of AmeriGas and the
way in which it does business. As such, key business information, strategic plans and other highly
confidential information about AmeriGas’s current and future business have been disclosed to me,
and I will participate in numerous discussions and decision-making on these issues. As a member of
AmeriGas’s Senior Management Team, I will participate in important strategic reporting, budgeting
and planning meetings where highly confidential information and plans are disclosed, discussed and
developed by the senior officers and managers of AmeriGas.

C. Accordingly, in consideration for my employment in this Vice President, Finance and Chief
Financial Officer position and the compensation and employee benefits that I will receive for
holding this position, including but not limited to, the new enhanced annual bonus plan, I agree to
the terms of this Confidentiality and Post-Employment Activities Agreement as follows:

1. Recitals.

The recitals contained in the lettered paragraphs above are hereby incorporated and made a
part of this Agreement.

2. Definitions.

(a) The term “Confidential Information” includes, but is not limited to, information, whether
in tangible form or otherwise, concerning business and marketing plans; past, present and
prospective customer identities, lists, credit information and gas usage patterns; pricing and
marketing policies and practices; financial information; acquisition and strategic plans; and other
operating policies and practices.

(b) The term “Territory” refers to each of the 50 states of the United States and such U.S.
territories and foreign nations in which AmeriGas distributes propane or otherwise sells goods or
services during the two-year period preceding the termination of my employment. In the event that
I am assigned to another territory or my territory is modified, the term “Territory” shall include
all territories for which I was responsible during the two-year period prior to the termination of
my employment.

3. Confidential Information and AmeriGas Property.

(a) I will protect the Confidential Information of AmeriGas and its predecessors and
affiliates from disclosure and will not divulge it during or after my employment to any other
person or entity not associated with AmeriGas.

(b) All reports, manuals, memoranda, computer disks and tapes and other materials made
available to me by AmeriGas during the performance of my duties are the property of AmeriGas, and I
will use all such property exclusively for AmeriGas’s benefit and will return it, including copies,
to AmeriGas at the termination of my employment.

4. Prohibited Post-Employment Activities.

For a period of two years after the termination of my employment with AmeriGas for any reason:

(a) Except as provided in paragraphs 4(b) below, I will not directly or indirectly: (i) own or
operate; (ii) acquire an equity or partnership interest or a controlling interest of any other kind
in; (iii) accept employment from; or (iv) serve as a director, officer, partner, consultant, or
advisor of or to, any business that distributes propane in my Territory or that sells goods or
provides services that compete with goods sold or services provided by AmeriGas in my Territory as
of the date of the termination of my employment without first obtaining the written consent of the
Chairman of the Board of Directors of AmeriGas Propane, Inc.

(b) In the event that my employment is terminated by the Company based upon my failure to meet
the performance or financial objectives established for my position and the Company, in its sole
discretion, determines that such failure on my part was not deliberate, the term of enforcement for
Paragraph 4(a) shall be calculated in the following manner: for every twenty (20) days of severance
payment that I receive, the term of enforcement for Paragraph 4(a) shall equal one (1) calendar
month; provided, however, that in no event will the term of enforcement for Paragraph 4(a) be less
than six (6) months.

(c) It is understood and agreed that Paragraph 4(a) will not prevent me from accepting
employment with a business that distributes alternative energy (i.e., electricity, natural gas or
fuel oil) or that sells goods or provides services in the alternative energy market.

(d) Nothing in paragraph 4(a) above shall prohibit me from passively investing in a publicly
held business that competes with AmeriGas provided my investment is less than 1% of the outstanding
stock or market value of the business and I do not otherwise violate paragraph 3 of this Agreement.

(e) I will not, nor will I induce any other person or entity to employ, or offer employment in
a competing business in my Territory to any employee of AmeriGas over whom I had direct
or indirect supervisory responsibility or with whom I worked, or who was employed by AmeriGas
within my Territory during the two-year period prior to the termination of my employment.
Furthermore, I shall not induce or attempt to induce any employee to terminate his or her
employment with AmeriGas.

5. Remedies.

(a) I understand that if I violate this Agreement, AmeriGas will suffer irreparable harm;
therefore, in addition to any other remedies available to it, AmeriGas will be entitled to seek and
obtain injunctive or equitable relief, including orders prohibiting violations of this Agreement.

(b) In any legal proceeding in which AmeriGas obtains injunctive or equitable relief or
damages against me arising out of my violation of this Agreement, AmeriGas shall be entitled to
recover from me its reasonable attorneys’ fees and costs.

(c) The failure by AmeriGas to insist on my compliance with this Agreement or to enforce it in
any particular circumstance will not constitute a waiver by AmeriGas of its rights to seek relief
for any other or subsequent breach of this Agreement.

6. Additional Provisions.

(a) This Agreement shall continue to be in full force and effect without execution in the
event that: (i) I am employed by AmeriGas in another position or transferred to another territory;
(ii) I take a leave of absence; or (iii) there are periods between active employment during which I
do not perform services for AmeriGas.

(b) This Agreement was, and shall be deemed to have been, made in the State of Pennsylvania.
It shall be governed by the laws of the State of Pennsylvania without regard to that state’s choice
of law provisions.

(c) The Court of Common Pleas of Montgomery County and the Federal District Court for the
Eastern District of Pennsylvania shall have exclusive jurisdiction over disputes arising out of or
relating to this Agreement except: (i) if I or AmeriGas desire to add a necessary party to the
action over whom the above-referenced courts would not have personal jurisdiction; or (ii) it is
necessary for me or AmeriGas to file an action or motion in another jurisdiction in order to
enforce any judgment or relief obtained from the above referenced courts. Accordingly, both
AmeriGas and I agree to submit to the jurisdiction and venue of the above-referenced courts and,
subject to the above stated exceptions, each of us agrees to waive any right to contest personal
jurisdiction and venue before such courts or to seek to transfer or otherwise object to or
challenge the forums designated herein.

(d) I will disclose the existence of this Agreement to all of my prospective employers. I
authorize AmeriGas to disclose the existence of this Agreement and to provide a copy of this
Agreement to any prospective or actual employers.

(e) I have read and understood this Agreement, believe it to be reasonable, and am signing it
voluntarily and in consideration of the benefits I will receive under it. I acknowledge that my
obligations under this Agreement will not impose an unreasonable economic hardship on me.
I further recognize that this Agreement may be enforced against me by a court of law or equity. I
also understand that the execution of this Agreement is a requirement of my employment with
AmeriGas and that AmeriGas will expect me to adhere strictly to the terms of this Agreement.

(f) The provisions of this Confidentiality and Post-Employment Activities Agreement constitute
the entire Agreement between myself and AmeriGas regarding AmeriGas’s Confidential Information and
my post-employment obligations, which Agreement cannot be varied except by a writing signed by me
and the Chairman of the Board of Directors of AmeriGas Propane, Inc. Notwithstanding the
foregoing, the provisions of this Agreement are in addition to, and not a limitation or
substitution of, nor do they supersede the provisions of the Code of Business Conduct and Ethics or
AmeriGas’s Human Resources Policies.

(g) I hereby consent to AmeriGas’s assignment of this Agreement to any entity that acquires
through purchase, merger or otherwise, the assets or stock of, or any interest in, AmeriGas
Propane, L.P., AmeriGas Eagle Propane, L.P. or AmeriGas Partners, L.P., and its subsidiaries,
partnerships and affiliates.

(h) If any provision of this Agreement shall be determined to be invalid or unenforceable to
any extent, the parties to this Agreement authorize the court to modify it to the extent necessary
to make the provision enforceable. If any provision of this Agreement shall be determined to be
invalid or unenforceable to any extent, such invalidity shall not impair the operation of or affect
the remaining provisions hereof.

Price”) equal to the Closing Price of the Common Stock on August 16, 2005 or on such

Trust Company to the Issuer (the “Settlement Date”), against payment by the Issuer of

understand and agree that the delivery of the Shares by or on behalf of UBS upon the
payment of the Purchase Price by the Issuer is irrevocable and that as of the
Settlement Date the Issuer will be the sole beneficial owner of the Shares for all
purposes.

As compensation to UBS for its commitment and services hereunder, the Issuer on
the Settlement Date will pay to UBS by wire transfer of immediately available funds an
amount per share equal to the Commission for the Shares to be delivered by UBS
hereunder on the Settlement Date. The commission payable to UBS shall not be subject
to refund.

Section 3. Settlement.

(a) On the Settlement Date, the Calculation Agent shall establish a notional
Principal Account in an amount equal to the product of (x) the Number of Shares and
(y) the Purchase Price. The Calculation Agent shall adjust the Principal Account as
follows:

(i) The Principal Account shall be reduced on each Dividend Adjustment Date in
an amount equal to the product of (x) the number of Borrowed Shares and (y) the
Dividend Amount corresponding to such Dividend Adjustment Date; and

(ii) The Principal Account shall be reduced on the third day following the Last
Averaging Date in an amount equal to the product of (x) the Number of Shares
and (y) the Final Price.

On the first Trading Day immediately following the last day of the Execution Period
(“Calculation Date”), the Calculation Agent will calculate the Settlement Amount and,
if applicable, the Stock Settlement Amount, notify (the “Settlement Amount
Notification”) the Issuer of the Settlement Amount and, if applicable, the Stock
Settlement Amount and provide a schedule of its calculations thereof. The Calculation
Agent shall respond promptly to all questions raised by the Issuer relating to such
calculations. If the Issuer objects to the calculation of the Settlement Amount or
the Stock Settlement Amount or any other determination or calculation by the
Calculation Agent hereunder, the Issuer shall promptly notify the Calculation Agent,
and the Issuer and UBS agree to use their good faith best efforts to reach an
agreement as to the Settlement Amount or the Stock Settlement Amount or such other
determination or calculation. In the further event that the Issuer and UBS are not
able to reach an agreement, the Issuer and UBS shall appoint a third party with
sufficient expertise to determine the calculation of the Settlement Amount or the
Stock Settlement Amount or such other determination or calculation, and such
determinations or calculations shall be binding on both parties.

(b) On the third Trading Day immediately following the Calculation Date (the
“Payment Date”), if the Settlement Amount is positive, UBS shall pay the Settlement
Amount to the Issuer and, if the Settlement Amount is negative, the Issuer shall pay
the absolute value of such Settlement Amount to UBS; provided, however, that to the
extent that a Last Averaging Date has not been declared by UBS pursuant to the terms
of the other agreement between the parties hereto, in substantially the form hereof,
relating to the purchase of Shares by the Issuer and dated the date hereof, on or
prior to such Payment Date, the Issuer may elect to delay the payment of such
Settlement Amount to UBS until the date that is the Payment Date with respect to such
second agreement. Except as provided in paragraphs (c), (d) and (h) of this Section,
all payments to be made under this Section 3 shall be made on the Payment Date by wire
transfer of immediately available funds.

(c) If the Issuer is required to pay the Settlement Amount to UBS pursuant to
paragraph (b) of this Section, the Issuer may, at its option, satisfy the obligation
by the delivery to UBS of a number of whole shares of Common Stock (and a payment of
cash in lieu of fractional shares, if any) equal to the Stock Settlement Amount. In
order to exercise this option, the following conditions must be satisfied (each, a
“Condition on Net Share Settlement”) (i) the Issuer must notify UBS of its election to
have any Settlement Amount payable in shares of Common Stock no later than 30 days
prior to the First Possible Last Averaging Date (the “Stock Election Notice”), (ii)
the Issuer must enter into a registration rights agreement with UBS in form and
substance reasonably acceptable to UBS (the “Registration Rights Agreement”) not later
than the 10 days prior to the First Possible Last Averaging Date , which agreement
will contain, among other things, customary representations and warranties and
indemnification and other rights, including rights to customary opinions of counsel
and accountant’s “comfort letters,” relating to the registration of the Stock
Settlement Shares, the Make-whole Shares and any additional shares of Common Stock as
to which UBS is named as a selling securityholder in the Shelf Registration (the
“Registered Shares”); (iii) the Shelf Registration shall have been declared effective
by the Securities and Exchange Commission (the “SEC”) not less than five Trading Days
prior to the First Possible Last Averaging Date; and (iv) the Issuer shall use its
reasonable best efforts to maintain the effectiveness of the Shelf Registration until
all Registered Shares have been sold by UBS. Subject to paragraph 3(g) below, if any
of the conditions in the preceding sentence are not met, the provisions of this
paragraph (c) shall be inoperative and the Issuer shall be obligated to pay any
applicable Settlement Amount by wire transfer of immediately available funds. If the
Issuer complies with all of its obligations under this paragraph (c), then at 9:30
a.m. on the Payment Date, the Issuer shall deliver to UBS (i) a certificate or
certificates representing the fully paid and nonassessable Stock Settlement Shares, in
such denominations and in such names as UBS may specify and (ii) the cash payment, if
any, in lieu of fractional shares by wire transfer of immediately available funds.
The parties understand and agree that the deliveries made pursuant to the preceding
sentence shall be irrevocable and shall satisfy in full the Issuer’s obligations under
this Section 3.

If the Issuer delivers Stock Settlement Shares to UBS pursuant to this paragraph (c)
and within ten Trading Days after the Payment Date, UBS resells all or any portion of
the Stock Settlement Shares and the net proceeds received by UBS upon resale of such
 shares exceeds the Settlement Amount (or if less than all of the Stock Settlement
Shares are resold, the applicable pro rata portion of the Settlement Amount), UBS
shall promptly refund in cash such difference to the Issuer; provided that UBS may, at
its option, satisfy its obligation under this sentence by returning to the Issuer any
portion of the Stock Settlement Shares that would, if sold, have resulted in net
proceeds in excess of the Settlement Amount. In the event that such net proceeds are
less than the Settlement Amount (or if less than all of the Stock Settlement Shares
are resold, the applicable pro rata portion of the Settlement Amount), the Issuer
shall pay in cash or additional shares of Common Stock (the “Make-Whole Shares”) such
difference (the “Make-Whole Amount”) to UBS promptly after receipt of notice thereof.
In the event that Issuer elects to pay the Make-whole Amount in additional shares of
Common Stock, the requirements set forth in this paragraph (c) with respect to payment
of the Settlement Amount in Shares, including make-whole requirements, shall apply,
such that UBS shall pay to the Issuer any such excess and the Issuer shall pay to UBS
in cash or Make-Whole Shares any additional Make-Whole Amount. In calculating the net
proceeds from the resale of any Stock Settlement Shares there shall be deducted from
such proceeds any amount equal to the customary underwriting discount or commission
for underwritten offerings of common stock by companies comparable to the Issuer
multiplied by the total number of Shares sold for the account of UBS pursuant to a
Shelf Registration.

(d) Notwithstanding any other provision in this Agreement, if Issuer exercises
its right pursuant to Section 3(c) above, Issuer shall not be obliged to deliver, in
connection with this Agreement, in excess of 15,000,000 Shares of Common Stock, as
recalculated from time to time (the “Determined Amount”). In the event that, but for
this Section 3, Issuer would be obliged to deliver a number of Shares of Common Stock
equal to the Determined Amount plus the Excess Shares, Issuer agrees to (x) satisfy
its remaining obligation by cash payment; or (y) (i) use its reasonable best efforts
to increase its number of authorized shares, thereby increasing the Determined Amount,
to the extent necessary so that, but for this Section 3, the number of Shares of
Common Stock Issuer would be obliged to deliver does not exceed the (recalculated)
Determined Amount and (ii) allocate such newly authorized shares of Common Stock in
satisfaction of Issuer’s delivery obligations under this Agreement in priority to any
other use of such Common Stock. For the avoidance of doubt, the obligation of Issuer
to so use its reasonable best efforts is an ongoing obligation.

(e) Issuer hereby represents and warrants that it will:

(i) calculate the Determined Amount based on the maximum
amount able to be calculated in accordance with EITF 00-19 or
any successor financial statement guidance; and

(ii) in respect of all equity derivative transactions in
respect of which Issuer’s equity securities constitute (all or
part of) the instruments underlying such transactions (the
“Derivative Trades”), use the same methodology to derive the
Determined Amount (howsoever described) applicable to each
Derivative Trade as is used to derive the Determined Amount
for this Agreement.

(f) UBS agrees that, in respect of any obligations Issuer has duly elected be
satisfied pursuant to Section 3(c) above, in the event of Issuer’s bankruptcy, UBS
shall not have rights in bankruptcy that rank senior to the rights in bankruptcy of
common shareholders of Issuer.

(g) If the Issuer has used its best efforts to satisfy the Conditions on Net
Share Settlement but has been unable to because the Shelf Registration is not declared
effective by the SEC within the time set out in paragraph 3(c) (or, where UBS has
previously agreed to extend such period based on a request by the Issuer pursuant to
paragraph 3(g)(ii), within such period as extended pursuant to paragraph 3(g)(ii)),
then the Issuer may elect to:

	 	(i)	 	deliver the relevant
number of Shares to UBS in which case:	 

(A) the day on which the Issuer makes such an election to receive such Shares
from Issuer is the “Issuer Election Date”, and

(B) Issuer shall withdraw any Registration Statement filed with the SEC in
connection with the Shares, and

(C) Issuer will enter into a private placement purchase agreement with UBS in
form and substance acceptable to UBS no later than the next Trading Day following the
Issuer Election Date, and

(D) Issuer shall deliver to UBS such Shares on the Settlement Date which, for the
purposes of this paragraph 3(g)(i)(D), shall be the third Trading Day following the
Issuer Election Date, and

(E) in addition to any Make-whole Amount payable by Issuer pursuant to paragraph
3(c), Issuer shall deliver to UBS such additional Shares until UBS has realized actual
net proceeds upon resale of such Shares equal to the Settlement Amount. At its
election, UBS may by a written notice to Issuer retain a number of Shares delivered by
Issuer pursuant to this paragraph 3(g)(i). If UBS so elects, UBS shall be deemed to
have sold each such retained Share for an amount equal to the price per Share obtained
by UBS in the last Share sold by UBS prior to sending written notice of its intention
to retain Shares to Issuer. In no event will UBS be obligated to exercise its right
to retain Shares; or

(ii) request UBS to extend the period within which the Registration Statement is
to be declared effective by the SEC for a further period specified in writing by UBS
at the time of such extension.

(h) If UBS is required to pay the Settlement Amount to the Issuer pursuant to
paragraph (b) of this Section, the Issuer may, at its option, elect that UBS satisfy
the obligation by the delivery to the Issuer of a number of whole shares of Common
Stock (and a payment of cash in lieu of fractional shares, if any) equal to the Stock
Settlement Amount. In order to exercise this option, the Issuer must notify UBS of
its election to have any Settlement Amount payable in shares of Common Stock no later
than 15 days prior to the Payment Date (the “Stock Election Notice”). If the
condition in the preceding sentence is not met, the provisions of this paragraph (h)
shall be inoperative and UBS shall be obligated to pay any applicable Settlement
Amount by wire transfer of immediately available funds. If the Issuer complies with
all of its obligations under this paragraph (h), then at 9:30 a.m. on the Payment
Date, UBS shall deliver to the Issuer (i) a certificate or certificates representing
the fully paid and nonassessable Stock Settlement Shares, and (ii) the cash payment,
if any, in lieu of fractional shares by wire transfer of immediately available funds.
The parties understand and agree that the deliveries made pursuant to the preceding
sentence shall be irrevocable and shall satisfy in full UBS’ obligations under this
Section 3.

Section 4. Anti-dilution Adjustments.

(a) Subdivisions and Combinations of Common Stock. In the event that the
outstanding shares of the Common Stock shall be subdivided or split into a greater
number of shares of Common Stock where the effective date of such subdivision or the
record date for such split occurs during the Execution Period, the number of shares of
Common Stock referred to herein shall be deemed to be proportionately increased and
the Final Price and Discount shall be deemed to be proportionately decreased;
conversely, in case outstanding shares of Common Stock shall each be combined into a
smaller number of shares of Common Stock through a combination of shares of Common
Stock or a reverse stock split where the effective date of such combination or the
record date for such reverse stock split occurs during the Execution Period, the
number of shares of Common Stock referred to herein shall be deemed to be
proportionately decreased and the Final Price and Discount shall be deemed to be
proportionately increased. Any adjustment pursuant to this paragraph (a) shall become
effective (i) in the case of a subdivision or combination of the Common Stock, at the
close of business on the effective date for such subdivision or combination or (ii) in
the case of a stock split or reverse stock split, at the close of business on the
record date for such stock split or reverse stock split.

(b) Merger Events. In respect of each Merger Event, UBS and the Issuer
or the person formed by such consolidation or resulting from such merger or which
acquired such assets or which acquires the Issuer’s Common Stock, as the case may be,
shall negotiate in good faith to amend this Agreement to give appropriate effect to
such transaction.

If payment is required of the Issuer in connection with a Merger Event, the
Issuer shall have the right, in its sole discretion, to elect (the “Extraordinary
Transaction Election”) to satisfy any such payment obligation by Net Share Settlement
of this Transaction; provided that, in connection with a “Share-for-Combined” Merger
Event or “Share-for-Other” Merger Event, the Extraordinary Transaction Election is
available to satisfy only the percentage of such payment obligation equal to the
percentage of the non-cash consideration over the total Combined Consideration (in the
case of a “Share-for-Combined” Merger Event) or total Other Consideration (in the case
of a “Share-for-Other” Merger Event). The remaining percentage of such payment
obligation must be satisfied in cash. The Issuer shall make any election to settle
the Transaction by way of Net Share Settlement within two Trading Days of the
Announcement Date but in any event not less than twenty Trading Days prior to the
effective date of such merger.

(c) Tender Offers. In the event an offer is made to the holders of Common
Stock to tender shares of Common Stock for cash, UBS and the Issuer shall negotiate in
good faith to amend this Agreement to give appropriate effect to such event.

(d) Adjustments. In the event that the Issuer objects to any adjustments made
pursuant to this Section 4, the Issuer shall promptly so notify UBS, and the Issuer
and UBS agree to use their good faith best efforts to reach an agreement as to the
adjustment. In the further event that the Issuer and UBS are not able to reach an
agreement in respect of any such adjustment, or any of the events contemplated by this
Section 4, the Issuer and UBS shall appoint a third party with sufficient expertise to
determine the adjustment and such adjustment shall be binding on both parties.

Section 5. Acknowledgement.

The Issuer acknowledges and agrees that it is not relying, and has not relied,
upon UBS or Agent with respect to the legal, accounting, tax or other implications of
this Agreement and that it has conducted its own analysis of the legal, accounting,
tax and other implications of this Agreement. The Issuer further acknowledges and
agrees that neither UBS nor Agent has acted as its advisor in any capacity in
connection with this Agreement or the transactions contemplated by this Agreement.
The Issuer acknowledges that neither UBS nor Agent is acting as the agent for the
Issuer in effecting any purchase of Common Stock pursuant to this Agreement. The

with applicable law, may from time to time effect transactions, for their own account
or the account of customers, and hold positions, in securities or options on
securities of the Issuer and that UBS and its affiliates may continue to conduct such
transactions during the Execution Period.

Section 7. Indemnification.

In the event that UBS becomes involved in any capacity in any action, proceeding
or investigation (“Proceeding”) brought by or against any person in connection with
any matter referred to in this Agreement, the Issuer periodically will reimburse UBS
for its reasonable out-of-pocket legal and other expenses (including the reasonable
cost of any investigation and preparation) incurred in connection therewith; provided
that such expenses will be promptly refunded to the Issuer to the extent incurred in
connection with a matter as to which UBS is not entitled to indemnification under this
Section 7. The Issuer also will indemnify and hold UBS harmless against any losses,
claims, damages or liabilities to which UBS may become subject in connection with any
matter referred to in this Agreement, except to the extent that any such loss, claim,
damage or liability results from the gross negligence, bad faith or willful misconduct
of UBS. If for any reason the foregoing indemnification is unavailable to UBS or
insufficient to hold it harmless, then the Issuer shall contribute to the amount paid
or payable by UBS as a result of such loss, claim, damage or liability in such
proportion as is appropriate to reflect not only the relative benefits received by the
Issuer, on the one hand, and UBS, on the other hand, in the matters contemplated by
this Agreement but also the relative fault of the Issuer and UBS with respect to such
loss, claim, damage or liability and any other relevant equitable considerations. The
relative benefits to the Issuer, on the one hand, and UBS, on the other hand, shall be
in the same proportion as the Aggregate Purchase Price bears to the commissions
received by UBS pursuant to the last paragraph of Section 2. The reimbursement,
indemnity and contribution obligations of the Issuer under this Section 7 shall be in
addition to any liability which the Issuer may otherwise have, shall extend upon the
same terms and conditions to any affiliate of UBS and the partners, directors,
officers, agents, employees and controlling persons (if any), as the case may be, of
UBS and any such affiliate and shall be binding upon and inure to the benefit of any
successors, assigns, heirs and personal representatives of the Issuer, UBS, any such
affiliate and any such person. The Issuer also agrees that UBS nor any of such
affiliates, partners, directors, officers, agents, employees or controlling persons
shall have any liability to the Issuer for or, in connection with any matter referred
to in this Agreement except to the extent that any losses, claims, damages,
liabilities or expenses incurred by the Issuer result from the gross negligence, bad
faith or willful misconduct of UBS in effecting the transactions that are the subject
of this Agreement. The foregoing provisions shall survive any termination or
completion of this Agreement. UBS promptly will notify the Issuer upon receipt of
actual notice of a Proceeding with respect to which indemnity or reimbursement of
expenses is sought hereunder. The Issuer may, at its option, assume the defense of
any such Proceeding, including the employment of counsel reasonably satisfactory to
UBS. UBS shall have the right to employ separate counsel in any such Proceeding and
to participate in the defense thereof, but the fees and expenses of such counsel shall
be at the expense of UBS, unless (i) the Issuer shall have failed in a timely manner
to assume the defense thereof and employ counsel as provided above or (ii) the named
parties to any such Proceeding include UBS and the Issuer and UBS shall have been
advised in writing by counsel that there may be one or more legal defenses available
to it that are different from or in addition to those available to the Issuer,
provided that the Issuer shall not in any event be responsible hereunder for the fees
and expenses of more than one firm of separate counsel in connection with any
Proceeding. UBS will not settle any Proceeding in respect of which indemnity or
reimbursement of expenses may be sought hereunder, whether or not the Issuer is an
actual or potential party to such Proceeding, without the Issuer’s prior written
consent.

Section 8. Termination Event.

Upon the occurrence of a Termination Event and so long as such Termination Event
shall be continuing, UBS may, in its discretion, by notice to the Issuer (the date of
such notice and the notice referred to in the succeeding clause being referred to
herein as the “Notice Date”), direct that the Execution Period shall forthwith
terminate on the date specified in such notice (the “Termination Event Termination
Date”). In such an event, (i) the Execution Period shall terminate on the Termination
Event Termination Date, (ii) the Principal Account shall be reduced on such date by an
amount equal to the sum of (A) the product of (x) the number of Hedge Account Shares
and (y) the arithmetic average of daily volume-weighted average prices of Shares in
each Trading Day from the First Averaging Date up to and excluding the Notice Date, as
listed on Bloomberg Screen Volume at Price Page and (B) the total purchase price paid
by UBS for the Shares of Common Stock that are purchased by UBS during the period
commencing on and including the Notice Date to and including the Termination Event
Termination Date in order to cover the remaining number of Borrowed Shares, (iii) the
Principal Account shall be increased to reflect an appropriate accrual of interest at
the Federal Funds Open Rate, as reasonably determined in good faith by the Calculation
Agent, to reflect interest earned by UBS in respect of the aggregate Purchase Price
received from the Issuer, (iv) the Principal Account shall be decreased to reflect
UBS’s actual cost of borrowing shares, as reasonably determined in good faith by the
Calculation Agent, of Common Stock to hedge its obligations hereunder and (v) the
Settlement Amount shall be further adjusted by the amount that UBS reasonably
determines in good faith to be its total losses and costs in connection with the early
termination of this Agreement, including any loss of bargain, cost of funding, or loss
or cost incurred as a result of its terminating, liquidating, obtaining or
reestablishing any hedge or related trading position. In the event that the Issuer
objects to any adjustments made pursuant to this Section 8, the Issuer shall promptly
so notify UBS, and the Issuer and UBS agree to use their good faith best efforts to
reach an agreement as to the adjustment. In the further event that the Issuer and UBS
are not able to reach an agreement in respect of any such adjustment, the Issuer and
UBS shall appoint a third party with sufficient expertise to determine the adjustment
and such adjustment shall be binding on both parties.

Section 9. Miscellaneous.

(a) Severability. If any term, provision, covenant or restriction of
this Agreement is held by a court of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions, covenants and restrictions set
forth herein shall remain in full force and effect and shall in no way be affected,
impaired or invalidated.

(b) Assignment. Neither the rights under this Agreement nor the
obligations created by this Agreement shall be assignable or delegable, in whole or in
part, by either party hereto without the prior written consent of the other (which
consent shall not be unreasonably withheld), and any attempt to assign or delegate any
rights or obligations arising under this Agreement without such consent shall be void.

(c) Waivers, etc. No failure or delay on the part of either party in
exercising any power or right hereunder shall operate as a waiver thereof, nor shall
any single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. No amendment,
modification or waiver of any provision of this Agreement nor consent to any departure
by either party therefrom shall in any event be effective unless the same shall be in
writing and, in the case of a waiver or consent, shall be effective only in the
specific instance and for the purpose for which given.

(d) Beneficiaries. This Agreement shall be binding upon, and inure
solely to the benefit of, the Issuer, UBS and, to the extent provided in Section 7
hereof, the affiliates, partners, directors, officers, agents, employees and
controlling persons, if any, of UBS, and their respective successors, assigns, heirs
and personal representatives, and no other person shall acquire any rights hereunder.

(e) Rights of Set-Off. In addition to any rights of set-off a party may
have as a matter of law or otherwise, upon occurrence of a failure to perform at
maturity with respect to either party (the “defaulting party”), the other party (the
“non-defaulting party”) shall have the right, without prior notice to the defaulting
party or any other person, to set off any obligation of the defaulting party owing to
the nondefaulting party in respect of this Agreement against any obligations of the
nondefaulting party owing to the defaulting party in respect of the other agreement
between the parties hereto, in substantially the form hereof, relating to the purchase
of Shares by the Issuer and dated the date hereof. Nothing in this Section 9(e) will
have the effect of creating a charge or other security interest.

(f) Changes of Law. If, due to any change in applicable law or
regulations or the interpretation thereof by any court of law or other body having
jurisdiction subsequent to the date of this Agreement, performance of any provision of
this Agreement or any transaction contemplated thereby shall become impracticable or
impossible, the parties hereto shall use their reasonable best efforts to find and
employ an alternative means to achieve the same or substantially the same result as
contemplated by such provision.

(g) Confidentiality. Subject to any contrary requirement of law and to
the right of each party to enforce its rights hereunder in any legal action, each
party shall keep strictly confidential and shall cause its employees and agents to
keep strictly confidential the terms of this Agreement and any information of or
concerning the other party which it or any of its agents or employees may acquire
pursuant to, or in the course of performing its obligations under, any provision of
this Agreement. In the event disclosure is permitted pursuant to the preceding
sentence, the disclosing party shall (i) provide prior notice of such disclosure to
the other party, (ii) use its best efforts to minimize the extent of such disclosure
and (iii) comply with all reasonable requests of the other party to minimize the
extent of such disclosure. This Section 9(g) shall not prevent either party from
disclosing information as necessary to third-party advisors in connection with the
transactions contemplated hereby provided that such advisors agree to be bound by this
Section 9(g) as if a party hereto. UBS hereby consents to the issuance of a press
release by the Issuer announcing its entry into this Agreement and the filing with the
SEC of a copy of this Agreement.
