	 	4	 	MATURITY AND REDEMPTION
	 
	 	 	 	All the amounts drawn down under the Loan shall be fully repaid by the Borrower no later than
the Final Redemption Date. It is clear, therefore, without prejudice to the full application
of any other provision this Agreement may contain, that the Borrower shall have fully repaid
the Loan’s principal on the Final Redemption Date, and have paid any interest, commission
fees, tax, expenses and any other obligations that may have arisen thereof.
	 
	 	5	 	INTEREST
	 
	 	5.1	 	Accrual
	 
	 	 	 	The Loan’s principal drawn down and not repaid shall accrue interest in favor of the Lender at
the interest rate set forth in Clause 8.

	 	5.2	 	Annualized daily accrual during each Interest Period
	 
	 	 	 	Interest shall accrue on a daily basis and shall be calculated (based on a year containing three
hundred and sixty (360) days) according to the calendar days elapsed during each Interest
Period, including the first and excluding the last such day.

	 	6	 	INTEREST RATE
	 
	 	6.1	 	Interest Periods
	 
	 	 	 	For the purposes of calculating interest, the time interval between the date of the Drawdown
and the Final Redemption Date shall be divided into successive Interest Periods and the first
day of each such Interest Period shall coincide with the last day of the immediately
preceding Interest Period.

	 	6.1.1	 	Duration of Interest Periods. Unless set forth otherwise herein, the Interest
Periods shall be of three (3) months.
	 
	 	 	 	Notwithstanding the foregoing, no final date of an Interest Period under the Loan may
be later than the Final Redemption Date. In any event, the Loan’s last Interest
Period shall necessarily coincide with the Final Redemption Date, even though it
could involve such Interest Period lasting months and/or weeks and/or days.
	 
	 	6.1.2	 	Termination of an Interest Period on a non-business day. To calculate the
Interest Period should its last day not fall on a Business Day, interest shall mature on
the first subsequent Business Day, unless such day should correspond to the following
calendar month, in which case the Interest Period shall be construed to have matured on
the immediately preceding Business Day.

	 	6.2	 	Interest Rate
	 
	 	 	 	The nominal annual interest rate that applies to each Interest Period shall be determined
pursuant to the provisions set forth in Clause 8.
	 
	 	7	 	PAYMENT OF INTEREST
	 
	 	 	 	The interest accrued during an Interest Period shall be settled and paid by the Borrower into
the Payment Account on the date each Interest Period comes to an end.

- 15 -

 

	 	8	 	INTEREST RATE CALCULATION
	 
	 	8.1	 	Calculation
	 
	 	 	 	The nominal annual interest rate that applies to the Interest Periods into which the Drawdown
is divided as set forth herein shall be determined by the Lender by means of adding the
margin set forth in Clause 8.3 to the corresponding reference interest rate (or the relevant
replacement rate, if appropriate) of the Drawdown pursuant to Clause 8.2
	 
	 	8.2	 	Reference and replacement interest rates

	 	8.2.1	 	Reference Interest Rate. The reference interest rate shall be the 3-month
EURIBOR rate. EURIBOR is understood as the monetary market reference rate of the Euro
zone which, pursuant to the relevant rules laid down by the European Banking Federation,
as published on REUTERS’ EURIBOR1 screen, or whatever may replace it at any time, at
approximately 11 a.m. (CET) of the third Business Day immediately prior to the start of
the Interest Period in question, for deposits in Euros for the same term as that of the
Interest Period. If such rate does not appear on this screen for the period of time
indicated, the reference interest rate shall be calculated by means of the linear
interpolation of the two rates corresponding to the closest periods by excess or default
(or, otherwise, by applying the rate that corresponds to the closest period). Justified
expenses and corresponding taxes shall be added to such reference interest rate, which
is normally done when it is established on the interbank market.
	 
	 	8.2.2	 	Replacement Rate. Should it be impossible to determine the reference interest
rate according to subsection 8.2.1, a replacement interest rate determined as follows
shall be applied during this Interest Period:

	 	(i)	 	Amount of replacement rate: the replacement rate shall be the result
of the arithmetic average of the interbank interest rates offered by Reference
Institutions to leading banks in the European interbank market on the second
Business Day prior to the start of the Interest Period for deposits in Euros
during a period equal to the Interest Period in question (or, otherwise, for the
closest period, by applying the lower rate in event of equivalent time periods).
Justified expenses and corresponding taxes shall be added to such reference
interest rate, which is normally done when it is established on the interbank
market.
	 
	 	(ii)	 	Reference Institutions: The Lender may not in any way be considered a
Reference Institution.
	 
	 	(iii)	 	Mechanism used for establishing the replacement rate: During the
morning of the second Business Day prior to the starting date of the corresponding
Interest Period, the Lender shall request Reference Institutions to provide the
interbank interest rates applicable with which the Lender must calculate, on that
same day, the arithmetic average indicated in subsection (i) above. Should any
Reference Institution fail or be unable to indicate such interest rate, the
arithmetic average of Reference Institutions in the market shall be used, whenever
at least two institutions are available.
	 
	 	(iv)	 	Replacement Institutions of Reference: Any Institution of Reference
shall cease to be deemed as such when it ceases to provide the necessary
information with regard to one or more Interest Periods or if it is merges or is
taken over by one of the Lender or become the Lender through acquiring a stake in
the Loan related to this Agreement. Such Institutions of Reference shall be
replaced through a new appointment made by the Lender.

	 	8.2.3	 	Return to the ordinary interest rate. Replacement rates shall no longer be used
when the circumstances requiring their application cease to exist, thereby giving rise
to

- 16 -

 

	 	 	 	normal circumstances as from the following Interest Period, during which the
procedure for determining the reference interest rate shall be re-established.

	 	8.3	 	Margin

	 	8.3.1	 	Initially, the Margin that applies to the Drawdown shall amount to TWO POINT
SEVENTY-FIVE PERCENT (2.75%) on an annual basis. Nonetheless, such Margin shall be
amended, where appropriate, after 31 December 2009 on the basis of the Debt Ratio in
accordance with the procedure set forth in this Clause.
	 
	 	 	 	For purposes of the provisions contained in this Clause, the Borrower shall provide
the Ratio Compliance Certificate containing the Debt Ratio value resulting from the
Consolidated Financial Statements of each financial year, along with the annual
Consolidated Financial Statements to be provided to the Lender in accordance with the
provisions set forth in subsection 18.1.2 .

	 	8.3.2	 	For the purposes set forth in this Clause, the value of the new Margin
applicable according to the Debt Ratio shall be determined based on the Consolidated
Financial Statements for the year ending on the December 31, 2009.
	 
	 	8.3.3	 	If the result of the Debt Ratio is within the values indicated below, the
percentage applicable as a Margin of the Drawdown as from the First Interest Period that
starts on or after the December 31, 2009 and until the afore-mentioned ratio is
recalculated, shall be the margin indicated in the following table:

	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 
	 	 	 	 	 	 	Above	 	 	Above	 	 	Above	 	 	Above	 	 	 	 
	 	 	 	 	 	 	2.50x and	 	 	2.00x and	 	 	1.50x and	 	 	1.00x and	 	 	 	 
	 	 	 	 	 	 	equal to or	 	 	equal to or	 	 	equal or	 	 	equal to or	 	 	Equal to or	 
	Debt	 	Above	 	 	less than	 	 	less than	 	 	less than	 	 	less than	 	 	less than	 
	Ratio	 	3.00x	 	 	3.00x	 	 	2.50x	 	 	2.00x	 	 	1.50x	 	 	1.00x	 
	Margin
	 	 	4.50	%	 	 	3.00	%	 	 	2.75	%	 	 	2.50	%	 	 	2.25	%	 	 	2.00	%

	 	8.3.4	 	For the purposes set forth in subsection 8.3.3 above, the new percentage
applicable as a Margin of the Drawdown shall begin to apply to the Interest Periods
commencing on or after the date on which the Lender receives the Consolidated Financial
Statements and the corresponding Ratio Compliance Certificate from the Borrower.
	 
	 	8.3.5	 	If it were impossible to verify the Debt Ratio due to a breach by the Borrower
of its obligations to deliver the Financial Statements and the corresponding Ratio
Compliance Certificate, or if, at that time, any Termination Events were still pending
resolution or consent by the Lender, the applicable Margin shall be the highest on the
scale set forth in subsection 8.3.3 above until the Debt Ratio has been duly verified.
The corresponding Margin for Interest Periods according to the preceding scale that
commence after verifying the calculation shall be applied once again.

	 	8.4	 	Procedure used to set the interest rate

	 	8.4.1	 	Determination by the Lender. The Lender shall calculate the interest rate
applicable to each Interest Period and shall give the Borrower written notice thereof
during the second Business Day prior to the date on which the Interest period in
question starts (or, assuming that the replacement reference rate applies, as soon as
possible during the course of such Business Day).
	 
	 	8.4.2	 	Binding nature of the determination, errors excepted. The interest rate
determined by the Lender shall be binding for the Borrower, errors excepted, in which
case, the relevant correction shall be made.

- 17 -

 

	 	8.5	 	Market breakout

	 	8.5.1	 	Market breakout: notice. If, due to exceptional circumstances, the Lender
cannot make the debit transactions necessary on the interbank monetary market for
financing the funds loaned according to the corresponding deadline, currency and
amount agreed upon, it shall immediately give notice thereof to the Borrower.
	 
	 	8.5.2	 	Adaptation of Interest Periods and Interest rate. The duration of the
applicable Interest Period shall then be justifiably determined by the Lender in view
of the deadlines established on the market for debit transactions necessary for
continuing to finance the Loan, where appropriate. If these deadlines are one (1) day
or similar, the interest rate applicable shall be EONIA.
	 
	 	 	 	For the purposes established in this subsection, EONIA means the Euro Monetary
Market reference rate resulting from applying the appropriate valid agreement,
under the sponsorship of the European Banking Federation and the Financial Markets
Association (the currently agreement indicates the reference rate on the Telerate
screen between 6.45 p.m. and 7 p.m. (Central European Time) for loans with delivery
of funds on the Business Day on which the corresponding Interest Period starts),
for one-day deposits in Euros, plus justified expenses normally applicable to the
time determined on the interbank market, as well as corresponding taxes.
	 
	 	8.5.3	 	Loan Renegotiation. If the exceptional prevailing circumstances foreseen in
subsection 8.5.1 above prevent the Lender from making the debit transactions
indicated, the Lender shall determine loan renegotiation and the Borrower and Lender
shall negotiate the measures to adopt to adapt the loan related to this Agreement to
the new circumstances, in good faith. Assuming that the parties do not reach an
agreement in a maximum of thirty (30) calendar days as from the Lender’s decision and
notwithstanding the fact that such period shall not suspend any of the Borrower’s
obligations on account of this, this Agreement shall be terminated early at the end of
the period indicated. Any redemption resulting from the application of this subsection
shall be exempt from any commission or penalties.

	 	9	 	INTEREST ON ARREARS

	 	9.1	 	Accrual of interest on arrears of the outstanding principal
	 
	 	 	 	The matured outstanding principal amount of the Loan shall accrue interest on arrears as from
its maturity date without the need for a daily reminder, which shall be the interest rate
applicable by virtue of Clause 12.1, plus TWO HUNDRED BASE POINTS (200 b.p.) on the
understanding that the reference interest rate shall not be EURIBOR but EONIA (as set forth
in paragraph, 8.5.2).
	 
	 	9.2	 	Accrual of arrears interest on other unpaid amounts
	 
	 	 	 	Net interest not paid by the Borrower shall be capitalized on a monthly basis and, as a
result, the interest on arrears set forth in Clause 9.1 shall accrue.
	 
	 	9.3	 	Settlement and payment of interest on arrears
	 
	 	 	 	The interest on arrears set forth in Clauses 9.1 and 9.2 shall be settled and paid by the
Borrower on a monthly basis as from the start date of the arrears.
	 
	 	9.4	 	Court-imposed interest
	 
	 	 	 	The arrears interest set forth in clauses 9.1 and 9.3 shall also include court-imposed
interest for the purposes of the provisions set forth article 576.1 of the Civil Proceedings
Law (or in any other similar legal provisions that may replace it in the future).

- 18 -

 

	 	10	 	VOLUNTARY EARLY REDEMPTION

	 	 	 	Notwithstanding the provisions of Clause 4, the early voluntary redemption of the Loan shall
be governed by the following rules:

	 	10.1.1	 	Minimum amount, early redemption multiples and proportionality. Except for redemption
of the entire Loan, early voluntary redemption may only take place for a minimum amount
of THREE HUNDRED AND FIFTY THOUSAND EUROS (€ 350,000) or, should it be higher, in
multiples of such amount.
	 
	 	10.1.2	 	Prior notice of each early redemption. The Borrower shall give the Lender written
notice of its intention at least ten (10) Business Days prior (or shorter period
accepted by the Lender) to the date on which the redemption is to occur and state the
amount and the date of the early redemption that should, however, coincide with the
final date of an Interest Period.
	 
	 	10.1.3	 	Voluntary early redemption commission fee. Early voluntary redemption shall not
generate commission fees for the Lender, notwithstanding any Breakthrough Costs that may
arise, where appropriate, as long as the funds used to effectuate such redemption come
from the Borrower’s cash and bank or from any contribution made by its shareholders.
However, should such funds come from any other source of external financing, the
Borrower shall be obliged to pay the Lender, on the same date as the redemption is
performed, a commission fee amounting to ONE PER CENT (1%) of the Loan amount
outstanding redemption on such date.
	 
	 	10.1.4	 	Redemption on a non-business day. If any of the redemption dates does not fall on a
Business Day for any reason whatsoever, either due to it being an ordinary or early
voluntary redemption, it shall be construed that such redemption is to take place on the
following Business Day, unless such day falls in the following calendar month, in which
case payment must be effectuated on the immediately preceding Business Day.
	 
	 	10.1.5	 	Irrevocability of notice of early redemption . Once notice of early redemption has
been received by the Lender, it shall be deemed irrevocable unless set forth otherwise
in the Agreement.
	 
	 	10.1.6	 	Definitive nature. Any amounts redeemed early may not be drawn down again by the
Borrower.

	 	11	 	COMPULSORY EARLY REDEMPTION
	 
	 	11.1	 	Notwithstanding the provisions set forth in Clause 4, the Borrower shall redeem the Total
Amount of the Loan early without this accruing any commission for the Lender or any penalties
for the Borrower, without prejudice to the accrual of any Breakthrough Costs, where
appropriate, under the following circumstances and for the following amounts:

	 	11.1.1.	 	should a change of control come about in the Lender as set forth in Clause 12.5;
	 
	 	11.1.2.	 	should a legal breach as set forth in Clause 12.2 come about; and
	 
	 	11.1.3.	 	should an agreement between the Borrower and its executives be reached leading to
the early handover of the Treasury Stock to them due to any reason whatsoever as part
of their compensation pursuant to the corresponding variable remuneration plan, an
amount equivalent to the market price of the shares handed over shall be paid back as
early redemption.

	 	11.2	 	Notwithstanding the provisions set forth in Clause 4, the Borrower shall have to redeem the
Loan Amount early without it leading to any kind of commission fee for the Lender or any kind
of penalty for the Borrower, without prejudice to Breakout Costs, and only in the event that
on the corresponding date there were no further outstanding payments to be made under the
Syndicated Financing Agreement for the following items and the following amounts:

- 19 -

 

	 	11.2.1	 	should any Group company receive one or more instances of compensation for an annual
accumulated amount that exceeds two hundred thousand euros (€ 200,000) from any claim
made under the aegis of insurance policies taken out by such companies (apart from
third-party liability insurance), an amount equivalent to the compensation received
shall be destined to early redemption of the Loan Amount, except in the event that the
amounts received are applied to the repair or replacement of assets within one hundred
and eighty (180) days from the date of receiving the relevant compensation;
	 
	 	11.2.2	 	in the case of (i) the sale, leasing, transfer or disposal of any assets; or (ii) the
sale, transfer or disposal of shares and stakes in any of the Material Subsidiaries
belonging to the Borrower or any of the Guarantors where the total price obtained is not
reinvested in the Borrower’s business at market prices within the ninety (90) days
following the collection of the price, an amount equivalent to the total price thus
obtained shall be destined to the early redemption of the Loan Amount. However, when the
total price thus obtained is reinvested within the aforementioned deadline and exceeds
twenty million euros (€ 20,000,000), an amount equivalent to fifty per cent of such price
exceeding twenty million euros (€ 20,000,000) shall be destined to the early redemption
of the Loan Amount; and
	 
	 	11.2.3	 	should a Transaction in the Capital Markets come about, an amount equivalent to the
amount obtained from such transaction shall be destined to redeeming the Loan Amount.

	 	11.3	 	Redemption date. The Borrower shall proceed with the early redemption of the amounts
mentioned in subsections 11.1 and 11.2 above on the first date an Interest Period of the
Drawdown terminates, which takes place after the event that gave rise to the early redemption.
	 
	 	11.4	 	Prior notice of each early redemption. The Borrower shall (i) give the Lender in written
notice as soon as it is aware of the occurrence of any circumstance that may give rise to
compulsory early redemption pursuant to the provisions of subsections 11.1 and 11.2 above; and
(ii) have given the Lender written notice of the cause of such early redemption at least ten
(10) Business Days before the date on which it occurs (unless this results in a shorter period
from applying the provisions of subsection 11.3), indicating the amount and date of the early
redemption.
	 
	 	11.5	 	Irrevocability of the early redemption notification. Once notice of early redemption has been
received by the Lender, unless indicated otherwise in the Agreement, it shall be considered
irrevocable.
	 
	 	11.6	 	Definitive nature. The amounts redeemed early may not be drawn down again by the Borrower.
	 
	 	12	 	CHANGE OF CIRCUMSTANCES
	 
	 	12.1	 	Cost increase

	 	12.1.1	 	Repercussion. If, due to legal or regulatory provisions (or due to their
interpretation or application by the competent authorities), obligations or restrictions
are imposed on the Lender which, on account of its participation in this transaction,
implies for the latter an increase in the cost of funds taken in the interbank monetary
market to which the Lender turns for financing this Agreement or an increase in the
consumption of its own resources, or if limitations are imposed on the interest rates or
commissions fees entailing a reduction of revenue to which the Lender was entitled by
virtue of this Agreement, the Borrower shall be obliged to compensate the Lender.

- 20 -

 

	 	12.1.2	 	Exceptions. The provisions of subsection 12.1.1 above shall not apply to increases in
costs which, where appropriate, are covered by the application of other clauses of this
Agreement or which are due to behavior that is solely attributable to the Lender.
	 
	 	12.1.3	 	Calculation of the repercussion. Compensation by the Borrower in accordance with the
preceding subsections shall be set at the amount transferred by the Lender based on a
reasoned and sufficiently detailed justification submitted by the Lender.
	 
	 	12.1.4	 	Cancellation due to an increase in costs. Should the Borrower be obliged to offset an
increase in the Lender’s costs by virtue of the provisions of subsection 12.1.1, the
Borrower may cancel the Loan.

	 	12.2	 	Unforeseen breach of contract
	 
	 	 	 	If, at any time after the Signing Date, the fulfillment of any of the obligations set forth
under the Agreement should imply a breach of any legal or regulatory provision or orderly
compulsory measure by the Lender, or binding criteria for its interpretation, which is issued
by a competent official authority or body, the Lender may cancel all obligations arising from
this Agreement, by giving the Borrower notice thereof. In such circumstances, the Borrower
shall be obliged to reimburse the Loan amount to the Lender and, at the same time, to pay the
corresponding interest calculated up to the date on which payment is actually made, as well
as any expenses and other amounts that must be paid by virtue of this Agreement on the date
the interest period underway terminates (or, where appropriate, in the period legally
permitted, if this is shorter).

	 	12.3	 	Mitigation of consequences of the change in circumstances

	 	12.3.1	 	Mitigation. Should the Lender be affected by any of the circumstances indicated in
clauses 12.1 or 12.2, it shall strive to make them commercially reasonable to mitigate
their consequences.
	 
	 	 	 	The preceding subsection shall in no way limit or affect the Borrower’s obligations
under this Agreement.
	 
	 	12.3.2	 	Limitation of liability. The Borrower shall immediately indemnify the Lender for any
costs and expenses reasonably incurred by it, at the former’s consent, as a result of
actions carried out in compliance with subsection 12.3.1 above.
	 
	 	 	 	The Lender shall not be obliged to perform the actions set forth in subsection 12.3.1
if, in its reasonable opinion, this could prejudice it or if it is not totally
convinced that any expenses incurred shall be fully reimbursed.

	 	12.4	 	Favorable change of circumstances
	 
	 	 	 	Assuming that the circumstances described in Clause 12.1 directly and inversely increase
revenue for the Lender, the real advantage verified and experienced by the Lender shall be
reversed.

	 	12.5	 	Change of control
	 
	 	 	 	In addition to ordinary redemptions and obligatory redemptions set forth above in this
Agreement, the Lender may request the early redemption of the total amounts drawn down and
pending redemption related to the Loan, as well as payment of any interest, commission fees
and other expenses as these become due within at most fifteen (15) days as from the receipt
of the related request, on the assumption that a person or entity other than Abengoa, S.A.,
individually or acting jointly with others, obtains control of the Borrower after the Signing
Date.
	 
	 	 	 	The Borrower should notify the Lender of the occurrence of this takeover of control as soon
as it is informed.

- 21 -

 

	 	 	 	For these purposes, “control” shall be construed as:

	 	(a)	 	capacity or power (be it through ownership of shares, special power, agreement,
agency or another form) to:

	 	(i)	 	vote for or control the votes of over 50% of voting rights exercised
at the Borrower’s general meeting;
	 
	 	(ii)	 	appoint or dismiss all or over 50% of the members of the Borrower’s
board of directors; or

financial policies, which must be accepted by directors or similar personnel; or

	 	(b)	 	ownership of over 50% of part of the Borrower’s issued equity capital, which
corresponds to ordinary or another type of shares that, in each case, are entitled to
vote.

	 	 	 	Likewise, for these purposes, “acting jointly” means a group of parties who, in compliance
with a formal or informal contract or agreement, actively cooperate through directly or
indirectly purchasing shares in the Borrower’s equity capital with a view to obtaining or
consolidating control over the Borrower.

	 	13	 	COMMISSION FEES AND EXPENSES

	 	13.1	 	Drawdown commission fee
	 
	 	 	 	The Borrower shall pay the Lender a fee equivalent to FIFTY PERCENT (50%) of the Margin
applicable at any time and on an annual basis over the Total Sum of the part of the Loan not
drawn down, which shall be accrued daily from the Signing Date (included) up until the date
when the Drawdown Period of the Loan terminates and it shall be settled and payable by the
Borrower at the end of each calendar quarter.
	 
	 	13.2	 	Opening and study commission fee
	 
	 	 	 	The Borrower shall pay the Lender a commission fee for the opening and study of the Loan
jointly equivalent to 2.00% of the Loan Amount, which shall be due on the Signing Date and
shall be paid by the Borrower by authorizing the charging of the Payment Account on the first
of either of the following dates: (i) the date on which thirty (30) days have elapsed from
the Signing Date; or (ii) the date the Drawdown is made.
	 
	 	13.3	 	Expenses and taxes
	 
	 	 	 	The Borrower shall be responsible for paying any expenses and taxes arising from signing and
executing this Agreement and especially, court or out-of-court expenses and attorneys’ and
procurators’ fees (even when their involvement is not mandatory) or any others that may arise
from the preparation, interpretation, amendment or execution of this Agreement and other Loan
Documents, or guaranties or procedures necessary for their fulfillment (particularly
including notary’s fees for publicly recording this Agreement and/or other Loan Documents
public and issuing the first authorized copies thereof to the Lender).
	 
	 	 	 	The Borrower shall likewise be responsible for any expenses arising from advertisements and
publicity on the loan related to this Agreement and any other costs or expenses incurred by
the Lender by virtue of or due to this Agreement or the Loan related to it.
	 
	 	14	 	TAXES
	 
	 	14.1	 	Net payment of taxes
	 
	 	 	 	All principal amounts, interest, commissions, costs, expenses or any other amounts that must
be paid by the Borrower under this agreement shall be net of any type of tax deduction or
retention. The Borrower shall therefore pay the Lender the additional amounts necessary for

- 22 -

 

	 	 	 	them to receive the whole amounts they would have received if these taxes, duties, rates or
controls did not exist.
	 
	 	 	 	The above shall only apply should the Lender not be domiciled in Spain whenever, before a
date established for paying interest, it has supplied the Borrower with a residence
certificate valid on such date issued by the appropriate tax department which confirms their
residence for tax purposes in a European jurisdiction and whenever they do not act through a
country or territory legally classed as a tax haven, pursuant to the provisions of Royal
Decree 1080/1991 of the 5th July.
	 
	 	 	 	Likewise, if the Lender demands any payment into an account of taxes on any sum received or
receivable by the former pursuant to this Agreement, which shall include a detailed
liquidation of the amount claimed, the Borrower, at the request of the Lender, shall
immediately indemnify the latter for such payment and for all kinds of interest, sanctions or
expenses that may arise or must be paid with regard to this and that are not attributable to
the Lender. The content of this paragraph shall not apply in case of any tax that encumbers
the net benefits of the Lender and that is applicable in the jurisdiction where the latter is
domiciled or from where it is loaning funds by virtue of this Agreement. All of the above
notwithstanding the fact that the provisions of the first paragraph of this Clause 14.1 apply
to eventual deductions or retentions applicable by virtue of the norms that rule such tax.
	 
	 	14.2	 	Tax letters of payment
	 
	 	 	 	If, at any time, the Borrower is ordered to make any deduction or retention with regard to
any amount owed by it pursuant to this Agreement (or, if their type of form according to
which such deductions or retentions must be calculated vary at a later date), the Borrower
shall immediately notify the Lender of this.
	 
	 	 	 	If the Borrower makes any type of payment pursuant to this Agreement with regard to which it
is requested to make a reduction or retention, it shall pay the tax authority or any other
competent entity, the total amount it is requested to deduct or retain within the period
permitted for such payment according to the applicable law, and shall provide the Lender with
the original payment letter (or a certified copy of it) in a maximum of thirty (30) days
following that on which payment has been made to the competent authority. The letter shall be
issued by such authority, which confirms payment made to it of all amounts that must be
deducted or retained with regard to the part of such payment that corresponds to the Lender.
	 
	 	14.3	 	Recovery and reversion of tax withholdings
	 
	 	 	 	Should an additional payment be made by the Borrower by virtue of Clause 14.1 and the Lender
considers that it has recovered the amount withheld, deducted or paid into account, which had
caused such additional payment, such an amount shall be collected by the Lender from the
Borrower as soon as possible after its actual recovery. Nevertheless, nothing in this Clause
14.3 shall oblige the Lender to alter the tax management followed to date.
	 
	 	14.4	 	Early cancellation due to an increase in costs.
	 
	 	 	 	If, in an unforeseeable and unexpected manner the Borrower is obliged to make additional
payments on account of the application of deductions or withholdings with regard to the
Lender by virtue of the provisions set forth in Clause 14.1, the Borrower may cancel and
redeem its share in the Lender’s Loan.
	 
	 	15	 	PAYMENTS AND INDEMNITIES

the relationship between the Lender and the Borrower other than the ones set forth

FIFTEEN MILLION EUROS (€ 15,000,000), and the maximum aggregate amount for the entire

given fiscal year the Borrower were to make investments below the annual established
limit, it would be allowed to increase the Capex limit for the next fiscal year in an
amount equivalent to the difference between the annual limit and the amount actually
incurred, although the Borrower shall only be allowed to do this once during the life of
the Loan.
	 
	 	 	 	The amount of the DTN Deferred Payments and any additional payments for Adjustments
to the DTN Purchase-Sale Price made by Telvent Export during the term of the Loan as

for the fiscal year in which such payments are made. Prior to making any such
payments, the Borrower shall provide the Lender with a certificate signed by a duly
authorized representative of the Borrower stating that there will be no breach of the
Financial Ratios as a consequence of making such payments.
	 
	 	 	 	The above notwithstanding, the Borrower shall be authorized to exceed the Capex
limits established in this section provided that it will result in a breach of the
Debt Ratio

- 33 -

 

	 	 	 	and the Debt Service Coverage Ratio in relation to the next to calculation periods of
the Financial Ratios as a consequence of having exceeded the limits. To this end, if
the Borrower decides to exceed the Capex limits, it shall be obliged to provide the
Lender with a certificate, signed by a duly authorized representative of the
Borrower, including a forecast of the Debt Ratio and Debt Service Coverage Ratio for
the next two periods covered by the Financial Ratio calculation, certifying
compliance once the total Capex figure has been recorded in the corresponding items
(including the excess of the limit established herein).
	 
	 	18.3.2	 	Interest Coverage Ratio. The Interest Coverage Ratio, determined as indicated in
section 18.3.6 below, should by higher than 3.5x.
	 
	 	18.3.3	 	Debt Service Coverage Ratio. The Debt Service Coverage Ratio, determined as indicated
in section 18.3.6 below, should by higher than 1.1x.

less than:

	 	 	 
	Year	 	Ratio

	2010 and thereafter
	 	2.50x

	 	18.3.5	 	Ratio Pay-Out. The Ratio Pay-Out, determined as indicated in section 18.3.6 below,
should be less than 50%.
	 
	 	18.3.6	 	Procedure for determining the value of financial ratios. The value of the Financial
Ratios shall be determined by the Certificate of Compliance of Ratios submitted by the
Borrower along with the annual or six-monthly Consolidated Financial Statements, both
calculated for the preceding twelve-month period.
	 
	 	 	 	It is hereby noted that, given the fact that Spain adheres to International
Accounting Standards which are subject to change by the accounting authorities in
Spain and the European Union, the parties have calculated the values for the
Financial Ratios indicated above on the basis of the International Accounting
Standards in force when the Borrower’s Consolidated Financial Statements for the
fiscal year ended 31 December 2007 were prepared. Hence, any changes to those
accounting standards, when they affect the calculation and/or levels of the Financial
Ratios, shall not have the effect of a breach of the terms of part 3.1 above.
	 
	 	 	 	If there is any such change, the parties will immediately commence good faith
negotiations to redefine the Financial Ratio calculations or levels, based on the
adjustments to the accounting standards. If they are unable to reach an agreement
within forty-five (45) days of starting the negotiations, the Lender may refer to
matter to an auditing firm of recognized international prestige to resolve any
possible discrepancies, whose decision shall preserve the substance of what has been
agreed by the parties to this Contract, particularly relative to the items used to
define Net Financial Debt, EBITDA, Cash Flow Available for Debt Service and Net
Financial Expenses. The expenses associated with that intervention shall be paid by
the Borrower.
	 
	 	 	 	At all times until an agreement is reached to redefine the Financial
Ratios, the Borrower shall provide sufficiently detailed information in a format
reasonably requested by the Lender to allow it to compare the level of
compliance of the Financial Ratios before and after the application of the new,
modified, reinterpreted or clarified accounting principles.

Borrower.
	 
	 	 	 	The Guarantors specifically consent to the assignments which may be carried out by
the Lender pursuant to the terms of Clause 19 and to that end specifically declare
that none of the terms of the guaranty granted herein shall be affected by any such
assignment. Moreover, the Guarantors waive the right afforded to them in article 1851
of the Civil Code, authorizing the Lender to grant any extensions and deferrals it
deem appropriate to the Borrower without this affecting the guaranty constituted by
them.
	 
	 	 	 	Under no circumstances shall this guaranty be altered, cancelled or replaced as a
consequence of any agreements reached by the Lender with the Borrower as part of a
bankruptcy proceeding, in which case the Guarantors’ obligations shall remain
unchanged, as though such proceedings had never taken place.
	 
	 	21.1.2	 	The Lender may require the fulfillment of the Guarantied Obligations directly from the
Guarantors according to article 1144 of the Civil Code and without the need to first
make a claim to the Borrower or to make a joint claim to the Borrower and/or the
Guarantors.
	 
	 	21.1.3	 	The Guarantors shall immediately proceed to the payment of the amounts claimed by the
Lender under this Guaranty, paying such amounts within at most four (4) Business Days
(during which interest shall accrue on the amounts owed as compensation pursuant to the
provisions set forth in Clause 9) counting from reception by the Guarantor in question
of the Lender’s requirement by depositing such amounts into the account the Lender may
have at such time, indicated in writing to the Guarantor.
	 
	 	21.1.4	 	The amount that may be required of the Guarantors shall be the amount of the resulting
balance. Nonetheless, any amounts whose guarantying may result in the a breach of the
prohibitions of financial assistance set forth in Article 81 of the Corporations Law may
never be subject to guaranty.
	 
	 	21.1.5	 	The lender expressly accepts the guaranty extended under the terms and conditions set
forth in this Clause 21.
	 
	 	21.1.6	 	For the purposes of determining the amounts which the Lender may at any moment claim
under this guaranty, the Guarantors expressly ratify the scheme to determine the amounts
owed by the Borrower as set forth in Clause 22.
	 
	 	21.1.7	 	This guaranty shall only cease to be in force once the Agreement has been terminated,
either early or as normal, and all amounts owed by the Borrower by virtue of this
Agreement have been fully paid. The fact of the Lender making a claim under
this guaranty shall no accounts constrain its entitlement to making further claims,
as long as the guaranty remains in force.

- 37 -

 

	 	21.1.8	 	In any event, any debt that should arise in favor the Guarantors against the Lender or
against the other Guarantors as a result of the execution of the guaranty set forth
herein shall be automatically subordinated to the obligations arising from this
Agreement in accordance with Articles 1839 and 1212 of the Civil Code.

	21.2 	 	Guarantors Guaranty obligation. The Borrower undertakes that the
obligations undertaken by it under this Agreement shall be guarantied at all times (i)
by the Material Subsidiaries (excluding DTN for these purposes); (ii) by Matchmind; and
(iii) in any event and additionally by any other Group companies, to the extent
necessary so that, notwithstanding the above and the terms of the following paragraph,
the Guarantors, jointly with the Borrower, represent at least 85% of the Total
Consolidated Assets, 85% of the consolidated EBITDA and 85% of consolidated Turnover
(without the guaranty extended by Matchmind being calculated for such
purposes).

	 
	 	 	In any event, when necessary over the Loan’s term, to account Matchmind’s EBIDTA,
Total Assets and Sales for the purposes of reaching the 85% stated in the paragraph
of the preceding section, the borrower and Telvent Outsourcing expressly undertake to
carry out as many actions as necessary to pledge 100% of Matchmind’s share capital as
collateral to guaranty obligations undertaken by the Borrower under the Loan and
under the Hedging Agreements, except in the case when, at that time, any legal or
contractual limitations avoiding the setting up of this right in rem were applicable,
in which case the Parties shall negotiate in good faith on a possible alternative
agreement, with this involving a Termination Event in the case that the
aforementioned negotiation did not lead to any agreements within a term of forty-five
calendar days from the date on which the need to account Matchmind’s EBIDTA, Total
Assets and Sales was reported for the purposes of reaching the 85%
stated beforehand.

	 
	 	 	Likewise, the Borrower undertakes to guaranty at all times the obligations it had
entered into under the Hedging Agreements held in relation to the Loan with the same
organizations acting as Guarantors under this Agreement over the term
of the same.

	 	21.2.2	 	Exceptions. The Borrower’s commitment with respect to the guaranty afforded by Group
companies referred to in section 26.2.1 above shall not, in any case, apply to:

	 	(i)	 	Project Companies;
	 
	 	(ii)	 	Acquisitions without Recourse and
	 
	 	(iii)	 	Group companies which are bound by legal restrictions on
guaranteeing the amounts owed by the Borrower under this Agreement (but only to
the extent that such restrictions affect all amounts, in which case they are
obligated to guaranty the amounts which are not subject to restrictions).
	 
	 	(iv)	 	Group companies in which the Borrower controls less than one
hundred percent (100%) of the share capital, except in those cases in which the
rest of the capital is controlled by another Group company.

	 	 	 	In any case, Guarantors, together with the Borrower, are obliged to contribute
jointly with at least 85% of the consolidated EBITDA, 85% of the Total consolidated
Assets and with 85% of consolidated Sales (adjusted to subtract EBITDA, Total Assets
and Project Company Turnover and Non-recourse Acquisitions).

	21.3	 	Accession of new Guarantors

	 	21.3.1	 	The Borrower shall forward to the Lender within three (3) months of the end of each
fiscal year a certificate issued by its auditors stating whether the Borrower has
acquired any direct or indirect stake in another entity (except the institutions
referred

- 38 -

 

	 	 	 	to in paragraphs (i) to (iv) of the previous section) and, if so, the volume of
assets and EBITDA of the entity. It is hereby noted that the Borrower shall not be
obliged to forward such a certificate to the Lender if there are no acquisitions to be
certified. The failure to submit a certificate by the stipulated deadline shall be
interpreted as a declaration by the Borrower that there are no acquisitions that require
certification.
	 
	 	21.3.2	 	If, pursuant to the terms of section 21.2.1 above, it were necessary to incorporate
additional Guarantors, the Borrower undertakes to ensure that such additional Guarantors
provide guaranties in identical terms to those established in Clause 21.1 and that they
assume the rest of the obligations inherent to the status of Guarantor in accordance
with the Financing Documents, by executing the corresponding Guarantor Accession Deed.
	 
	 	 	 	To this end, the Borrower shall require the additional Guarantors to appear before a
notary public to formalize the guaranty by executing the pertinent Guarantor
Accession Deed within ten (10) Business Days from the date on which the audited
Consolidated Annual Financial Statements referred to in section 18.1.1 are delivered
to the Lender.
	 
	 	 	 	The Borrower undertakes to deliver to the Lender simultaneously with the execution of
each Guarantor Accession Deed a legal opinion in relation to each new Guarantor
issued by a legal expert approved by the Lender, the format of which should be
substantially similar to the sample provided prior to the Signing Date for the
initial Guarantors.
	 
	 	21.3.3	 	Except as regards the guaranty constituted by Telvent Export and Matchmind (to which
the terms of this clause shall not apply), the guaranties provided by the Guarantors
shall be automatically extinguished in their entirety if a percentage of their shares is
sold to a third party or in the event of a business reorganization of the kind described
in section 18.2.14, provided that the Borrower can prove to the satisfaction of the
Lender that the remaining Guarantors, along with the Borrower, jointly contribute at
least 85% of the consolidated EBITDA, 85% of Total consolidated Assets and 85% of
consolidated Sales (adjusted to subtract EBITDA, Total Asserts and Sales of Project
Companies and Non-resource Assets).
	 
	 	 	 	Notwithstanding the automatic termination of the guaranty under the circumstances
mentioned, the Lender shall sign within thirty (30) Business Days from the date of
the notice by the Borrower or the Guaranty in question of the event which gave rise
to the extinguishment of the guaranty, any and all documents as may be required to
formalize the extinguishment.

          (a) Set forth on Schedule 1.8 hereto is an outline of the transaction mechanics (the “Closing Mechanics”),

(3) business days prior to the Closing Date,  Butler Holding
shall deliver to HSI a certificate (the “Closing Date
Certificate”), which shall set forth  estimates of the
Aggregate Preferred
Face Amount, the Refinancing Expenses  and the
Existing Net Debt.
The amounts set forth on the Closing Date Certificate shall be used for purposes of Closing Mechanics  at the Closing, provided that any payments and distributions made in accordance
with Schedule 1.8 shall be subject to adjustment following the
Closing as set forth in Section 1.8(b) below.

          (b)
Within ten (10) days after  the Closing, the Butler Group
shall deliver to Butler Holding  a statement setting forth the actual
Aggregate Preferred Face Amount, the Refinancing Expenses and
 Existing Net Debt (the “Final Closing Statement”), which statement  shall set forth in reasonable detail the actual Refinancing Expenses and Existing Net
Debt as of the Closing. If Butler Holding  delivers a dispute notice to the Butler Group within ten (10) days after receipt by Butler Holding of the Final Closing Statement, then Butler Holding and the Butler Group will attempt to resolve and finally determine and agree upon the Final Closing Statement as promptly as practicable.
If Butler Holding and the Butler Group are unable to agree upon the Final Closing
Statement within thirty (30) days any items remaining in dispute, at the request of either party at any time after the HSI Negotiation Period, shall be submitted to the Accounting  Firm to resolve such dispute pursuant to the dispute
resolution provisions of Section 2.2(c) hereof, mutatis mutandis. Upon final determination of the amounts set forth on the Final Closing Statement,
all payments and distributions made pursuant to the
Closing Mechanics shall be recalculated as though the amounts set forth on the Final Closing Statement were used for purposes of the Closing,  and each of the Butler Holding Members  and Butler Holding agrees to make such payments or distributions as may be
 necessary to
true-up any such  payments  and distributions to reflect the amounts set forth on the

hereby, HSI shall own, directly or indirectly, 50.1% of the outstanding equity interests in Butler Holding
and there shall be only one class of outstanding Equity Securities of
Butler Holding and MergerSub in accordance with the Closing Mechanics.

ARTICLE 2

PURCHASE PRICE ADJUSTMENTS

     2.1 Payments at Closing.

          (a) At least ten (10) days prior to the Closing, HSI will furnish to Butler Holding a
certificate (the “HSI Estimated Closing Working Capital Certificate”) setting forth an estimate of
HSI Closing Working Capital. In preparing the HSI Estimated Closing Working Capital Certificate,
HSI’s estimate of the HSI Closing Working Capital will be made in accordance with the Balance Sheet
Rules.

          (b) At least ten (10) days prior to the Closing, Butler Holding will furnish to HSI a
certificate (the “Butler Holding Estimated Closing Working Capital Certificate”) setting forth an
estimate of Butler Holding Closing Working Capital. In preparing the Butler Holding Estimated
Closing Working Capital Certificate, Butler Holding’s estimate of the Butler Holding Closing
Working Capital will be made in accordance with the Balance Sheet Rules.

          (c) At the Closing, (i) either (A) the Butler Holding Members (severally, in accordance with
their respective Pre-Closing Percentage Interests) shall pay HSI an amount of cash equal to the
excess, if any, of the Butler Closing Working Capital Payment (as defined below) over the HSI
Closing Working Capital Payment (as defined below) or (B) HSI shall pay the Butler Holding Members
(in accordance with their respective Pre-Closing Percentage Interests) an amount of cash equal to
the excess, if any, of the HSI Closing Working Capital Payment over the Butler Closing Working
Capital Payment:

               (ii) For purposes of this Section 2.1(c):

“Butler Closing Working Capital Payment” shall mean an amount, equal to the sum of:

          (W) the product of (1) the Butler Holding Post-Closing Percentage Interest
multiplied by (2) the excess, if any, of HSI Estimated Closing Working Capital over
HSI Target Closing Working Capital; plus

          (X) the product of (1) the HSI Post-Closing Percentage Interest multiplied by
(2) the excess, if any, of Butler Holding Target Closing Working Capital over Butler
Holding Estimated Closing Working Capital.

“HSI Closing Working Capital Payment” shall mean an amount, equal to the sum of:

          (Y) the product of (1) the HSI Post-Closing Percentage Interest multiplied by
(2) the excess, if any, of Butler Holding Estimated Closing Working Capital over
Butler Holding Target Closing Working Capital; plus

5

 

          (Z) the product of (1) the Butler Holding Post-Closing Percentage Interest
multiplied by (2) the excess, if any, of HSI Target Closing Working Capital over HSI
Estimated Closing Working Capital.

For the avoidance of doubt, for purposes of calculating the “excess, if any” in each of clauses
(W)(2), (X)(2), (Y)(2) and (Z)(2) above, if the result of such calculation does not yield a
positive number, such calculation shall be deemed to equal zero. For the purposes of illustration,
examples of the calculations to determine the Butler Closing Working Capital Payment, the HSI
Closing Working Capital Payment and the amounts, if any, to be paid pursuant to Section 2.1(c) are
set forth on Schedule 2.

     2.2 HSI Working Capital Adjustment.

          (a)
Within ninety (90) days after the Closing Date, HSI will
deliver to the Butler Group a
certificate (the “HSI Closing Working Capital
Certificate”) executed by HSI setting
forth an itemized statement of HSI Closing Working Capital. The HSI Closing Working Capital
Certificate will be prepared in accordance with the Balance Sheet Rules.

          (b)
If the Butler Group delivers written notice (the “HSI
Disputed Items Notice”) to HSI within
thirty (30) days after receipt by the Butler Group of the HSI Closing Working Capital Certificate, stating that
the Butler Group objects to any items in the HSI Closing Working Capital Certificate, specifying in reasonable
detail the basis for such objection and setting forth the Butler Group’s proposed modification to HSI Closing
Working Capital, HSI and the Butler Group will attempt to resolve and finally determine and agree
upon the HSI Closing Working Capital as promptly as practicable.

          (c)
If HSI and the Butler Group are unable to agree upon the HSI Closing Working Capital within
thirty (30) days after delivery of the HSI Disputed Items Notice (the “HSI Negotiation Period”),
any items remaining in dispute, at the request of either party at any time after the HSI
Negotiation Period, shall be submitted to the New York office of Ernst & Young (the “Accounting
Firm”). If the New York office of Ernst & Young is unwilling to serve as the Accounting Firm, then
an independent, nationally recognized accounting firm reasonably acceptable to each of HSI and
the Butler Group (which Accounting Firm shall not be HSI’s, Butler Holding’s, Darby’s, Burns’ or Oak
Hill’s or any of their respective Subsidiaries’ regular auditors) will resolve the items set forth
in the HSI Disputed Items Notice (the “HSI Disputed
Items”). If the Butler Group and HSI are unable
to agree upon the selection of an Accounting Firm within 10 days after the end of the HSI
Negotiation Period, HSI and the Butler Group shall each (at its own expense) select an independent
accounting firm and said firms shall promptly designate a third firm as the Accounting Firm. The
Accounting Firm will (i) resolve only the HSI Disputed Items, and (ii) make a determination of HSI
Closing Working Capital using the calculations set forth in the HSI Closing Working Capital
Certificate, as modified only by the Accounting Firm’s resolution of the HSI Disputed Items. The
Accounting Firm shall address only the HSI Disputed Items and may not assign a value greater than
the greatest value claimed for such item by either party or smaller than the smallest value claimed
for such item by either party. The determination of the Accounting Firm will be made within sixty
(60) days after being selected and will constitute an arbitral award that is final, binding and
non-appealable and upon which a judgment may be entered by a court with jurisdiction

6

 

thereover. The fees, costs and expenses of the Accounting Firm will be borne by the party
whose positions generally did not prevail in such determination, as determined by such Accounting
Firm (i.e., HSI or the Butler Group (severally in accordance with their respective Indemnification
Percentage Interests)), or if the Accounting Firm determines that neither party could be fairly
found to be the prevailing party, then such fees, costs and expenses will be borne fifty percent
(50%) by HSI and fifty percent (50%) by the Butler Group (severally in accordance with their
respective Indemnification Percentage Interests). If an Accounting Firm is required to resolve HSI
Disputed Items and Butler Holding Disputed Items, such disputes shall be combined and resolved
together to the extent practicable.

          (d) If the Butler Group does not deliver the HSI Disputed Items Notice to HSI within thirty (30)
days after receipt by the Butler Group of the HSI Closing Working Capital Certificate, the HSI Closing Working
Capital specified in the HSI Closing Working Capital Certificate will be conclusively presumed to
be true and correct in all respects and will be final and binding upon the parties.

          (e) HSI will provide the Butler Group and its accountants, lawyers and representatives with full
access at all reasonable times to (and shall be allowed to make copies of) the Schein Books and
Records and to any personnel of HSI reasonably requested by such persons, in each case in
connection with the final determination of the HSI Closing Working Capital or any dispute relating
thereto.

     2.3 Butler Holding Working Capital Adjustment.

          (a) Within ninety (90) days after the Closing Date, the Butler Group will deliver to HSI a
certificate (the “Butler Holding Closing Working Capital Certificate”) executed by the Butler Group setting
forth an itemized statement of Butler Holding Closing Working Capital. The Butler Holding Closing
Working Capital Certificate will be prepared in accordance with the Balance Sheet Rules.

          (b) If HSI delivers written notice (the “Butler Holding Disputed Items Notice”) to
the Butler Group within thirty (30) days after receipt by HSI of the Butler Holding Closing Working
Capital Certificate, stating that HSI objects to any items in the Butler Holding Closing
Working Capital Certificate, specifying in reasonable detail the basis for such objection and
setting forth HSI’s proposed modification to Butler Holding Closing Working Capital,
the Butler Group and HSI will attempt to resolve and finally determine and agree upon the Butler
Holding Closing Working Capital as promptly as practicable.

          (c) If the Butler Group and HSI are unable to agree upon the Butler Holding Closing Working
Capital within thirty (30) days after delivery of the Butler Holding Disputed Items Notice (the
“Butler Negotiation Period”), any items remaining in dispute, at the request of either party at any
time after the Butler Negotiation Period, shall be submitted to the named Accounting Firm set forth
in the first sentence of Section 2.2(c). If such firm is unwilling to serve as the Accounting
Firm, then an Accounting Firm reasonably acceptable to each of the Butler Group and HSI (which
Accounting Firm shall not be HSI’s,  Butler Holding’s,
Darby’s, Burns’ or Oak Hill’s or any of their respective Subsidiaries’ regular
auditors) will resolve the items set forth in the Butler Holding Disputed Items Notice (the “Butler
Holding Disputed Items”). If the Butler Group and HSI are unable to

7

 

agree upon the selection of an Accounting Firm within 10 days after the end of the Butler
Negotiation Period, HSI and the Butler Group  shall each (at its own expense) select an independent
accounting firm and said firms shall promptly designate a third firm as the Accounting Firm. The
Accounting Firm will (i) resolve only the Butler Holding Disputed Items, and (ii) make a
determination of Butler Holding Closing Working Capital using the calculations set forth in the
Butler Holding Closing Working Capital Certificate, as modified only by the Accounting Firm’s
resolution of the Butler Holding Disputed Items. The Accounting Firm shall address only the Butler
Holding Disputed Items and may not assign a value greater than the greatest value claimed for such
item by either party or smaller than the smallest value claimed for such item by either party. The
determination of the Accounting Firm will be made within sixty (60) days after being selected and
will constitute an arbitral award that is final, binding and non-appealable and upon which a
judgment may be entered by a court with jurisdiction thereover. The fees, costs and expenses of
the Accounting Firm will be borne by the party whose positions generally did not prevail in such
determination, as determined by such accounting firm (i.e., the Butler Group (severally in
accordance with their respective Indemnification Percentage Interests) or HSI), or if the
accounting firm determines that neither party could be fairly found to be the prevailing party,
then such fees, costs and expenses will be borne fifty percent (50%) by the Butler Group (severally
in accordance with their respective Indemnification Percentage Interests) and fifty percent (50%)
by HSI. If an Accounting Firm is required to resolve HSI Disputed Items and Butler Holding
Disputed Items, such disputes shall be combined and resolved together to the extent practicable.

          (d) If HSI does not deliver the Butler Holding Disputed Items Notice to the Butler Group within
thirty (30) days after receipt by HSI of the Butler Holding Closing Working Capital
Certificate, the Butler Holding Closing Working Capital specified in the Butler Holding Closing
Working Capital Certificate will be conclusively presumed to be true and correct in all respects
and will be final and binding upon the parties.

          (e) Butler Holding will provide HSI and its accountants, lawyers and representatives with full
access at all reasonable times to (and shall be allowed to make copies of) the Butler Holding Books
and Records and to any personnel of Butler Holding reasonably requested by such persons, in each
case in connection with the final determination of the Butler Holding Closing Working Capital or
any dispute relating thereto.

     2.4 Payments for Working Capital Adjustments. At such time as the HSI Closing Working Capital
and the Butler Holding Closing Working Capital are finally determined or otherwise agreed to in
writing by Butler Holding and HSI pursuant to Sections 2.2 and 2.3, then:

          (a) (i) Either (A) the Butler Holding Members (severally, in accordance with their respective
Pre-Closing Percentage Interests) shall pay HSI an amount of cash equal to the excess, if any, of
the Butler Post-Closing Working Capital Payment (as defined below) over the HSI Post-Closing
Working Capital Payment (as defined below) or (B) HSI shall pay the Butler Holding Members (in
accordance with their respective Pre-Closing Percentage Interests) an amount of cash equal to the
excess, if any, of the HSI Post-Closing Working Capital Payment over the Butler Post-Closing
Working Capital Payment; and

8

 

               (ii) For purposes of this Section 2.4(a), “Butler Post-Closing Working Capital Payment” shall
mean an amount, equal to the sum of:

          (W) the product of (1) the Butler Holding Post-Closing Percentage Interest
multiplied by (2) the excess, if any, of HSI Closing Working Capital over HSI
Estimated Closing Working Capital; plus

          (X) the product of (1) the HSI Post-Closing Percentage Interest multiplied by
(2) the excess, if any, of Butler Holding Estimated Closing Working Capital over
Butler Holding Closing Working Capital; and

“HSI Post-Closing Working Capital Payment” shall mean an amount, equal to  the sum of:

          (Y) the product of (1) the HSI Post-Closing Percentage Interest multiplied by
(2) the excess, if any, of Butler Holding Closing Working Capital over Butler
Holding Estimated Closing Working Capital; plus

          (Z) the product of (1) the Butler Holding Post-Closing Percentage Interest
multiplied by (2) the excess, if any, of HSI Estimated Closing Working Capital over
HSI Closing Working Capital.

For the avoidance of doubt, for purposes of calculating the “excess, if any” in each of clauses
(W)(2), (X)(2), (Y)(2) and (Z)(2) above, if the result of such calculation does not yield a
positive number, such calculation shall be deemed to equal zero. For the purposes of illustration,
examples of the calculations to determine the Butler Post-Closing Working Capital Payment, the HSI
Post-Closing Working Capital Payment and the amounts, if any, to be paid pursuant to Section 2.4(a)
are set forth on Schedule 2.

          (b) No adjustment to the HSI Closing Working Capital pursuant to this Article 2 shall
be considered a breach of any representation, warranty or other provision of this Agreement. No
adjustment to the Butler Holding Closing Working Capital pursuant to this Article 2 shall
be considered a breach of any representation, warranty or other provision of this Agreement.

owns or has the right to acquire any equity interest in any other Person and except as expressly
contemplated by this Agreement is not obligated to make any loans or equity contributions to any
Person.

     3.5 Foreign Qualifications. Schedule 3.5 sets forth a complete and accurate list of
each jurisdiction in which HSI or any of its Subsidiaries is qualified to do business as a foreign
entity in which the conduct of the Contributed Schein Vet Business or the ownership of the
Contributed Assets makes such qualification or licensing necessary, except for any jurisdiction(s)
in which the failure to so qualify would not have a Schein Material Adverse Effect.

     3.6 Financial Statements.

          (a) Attached hereto as Exhibit 3.6A are the (i) unaudited balance sheets of NLS as of
December 29, 2007 and December 27, 2008, and unaudited statements of income for the fiscal years
then ended, and (ii) unaudited balance sheet of NLS as of September 26, 2009 (“NLS September
Balance Sheet”), and an unaudited statement of income for the twelve fiscal month period then ended
(collectively, the “NLS Financials”). Except as set forth on Schedule 3.6A, the NLS
Financials fairly present, in all material respects, the financial condition of NLS as of the dates
thereof and results of operations of NLS for the periods shown therein, and were derived from the
books and records of NLS in conformity with GAAP consistently applied during the periods covered
thereby (except as otherwise stated therein and for the omission of footnotes and subject to year
end and other audit adjustments, which adjustments are, individually and in the aggregate,
immaterial).
None of the $1,031,584 expenses under the category “Medical Administration
Allocation” charges on Exhibit 3.6A for the twelve (12) fiscal month period ended September 26, 2009 contains any material
costs or expenses that directly support NLS.

          (b) Attached hereto as Exhibit 3.6B are the (i) unaudited Statement of Contributed
Assets and Assumed Liabilities of the Core Vet Business as of December 29, 2007 and December 27,
2008, and unaudited statements of income for the fiscal years then ended, and

11

 

(ii) unaudited Statement of Contributed Assets and Assumed Liabilities as of September 26,
2009 (“Core Vet September Statement”), and an unaudited statement of income for the twelve fiscal
month period then ended (collectively, the “Core Vet Financials”). Except as set forth on
Schedule 3.6B, (A) the Core Vet Financials have been derived from the accounting records
that underlie the consolidated financial statements of HSI as prepared as of the date hereof, which
have been prepared in accordance with GAAP consistently applied during the periods covered thereby
(except as otherwise stated therein or in the case of unaudited financial statements, subject to
year end and other audit adjustments, which adjustments are, individually and in the aggregate,
immaterial), (B) the net sales and direct costs have been determined in accordance with GAAP,
consistently applied, (C) all other expenses reflected on the Core Vet Financials were determined
and allocated in accordance with the principles, assumptions and methodologies on Exhibit
3.6C (the “Schein Allocation Methodologies”), which have been consistently applied to the Core
Vet Financials, (D) HSI has not made any material mathematical error in applying the Schein
Allocation Methodologies, and (E) none of the expenses under the category “Global SG&A Costs” on
Exhibit 3.6C, other than “Corporate Overhead”, contains any material costs or expenses that
directly support the Core Vet Business. The income statements in the Core Vet Financials fairly
present, in all material respects, the results of operations of the Core Vet Business for the
periods shown therein, in accordance with the application of the Schein Allocation Methodologies
and the immediately preceding sentence.

          (c) Butler Holding, BAHS and the Butler Holding Members acknowledge and agree that (i) the
Core Vet Business involves a carve out of operations of HSI, which are not free standing
operations, and (ii) they each hereby waive any right to challenge or assert any claims in respect
of the Schein Allocation Methodologies or the treatment of Corporate Overhead (referenced in
Exhibit 3.6C), including their impact in determining purchase price.

          (d) Without limiting the representations set forth in Section 3.6(a) above, except (i) for
liabilities shown on the NLS September Balance Sheet or the Core Vet September Statement, (ii) for
liabilities which have arisen in the ordinary course of business since the Balance Sheet Date,
(iii) for liabilities which are not Assumed Liabilities or liabilities allocated pursuant to the
Schein Allocation Methodologies, and (iv) as set forth on Schedule 3.6(d), neither HSI nor
any of its Subsidiaries has incurred any material liability or obligation of any nature in respect
of the Contributed Vet Business (whether absolute, accrued, contingent, liquidated or unliquidated)
which is required by GAAP to be reflected as a liability on a balance sheet of the Contributed
Schein Vet Business. Except as set forth in the Core Vet Financials or the NLS Financials, neither
HSI nor any of its Subsidiaries maintains any “off-balance sheet arrangement” (within the meaning
of Item 303(a)(4)(ii) of Regulation S-K of the Securities and Exchange Commission) relating to the
Core Schein Vet Business.

          (e) HSI and each of its Subsidiaries have in place systems and processes reasonably designed
to provide reasonable assurances regarding the reliability of the consolidated financial statements
of HSI.

     3.7 Absence of Certain Changes. Since the Balance Sheet Date, except as set forth on
Schedule 3.7, HSI and its Subsidiaries have conducted the Contributed Schein Vet Business
only in the ordinary course of business, in the same manner as heretofore conducted (except as may
be necessary to comply with Applicable Laws) and, with respect to the Contributed Schein

12

 

Vet Business, HSI and NLS, as applicable, have not (a) subjected the Contributed Assets to any
Lien, other than Permitted Liens, (b) acquired or disposed of any material assets, except in the
ordinary course of business, (c) suffered any damage, destruction or casualty loss (whether or not
covered by insurance) which individually or in the aggregate exceeds $150,000, (d) made any change
in its accounting, auditing or Tax methods, practices or principles, (e) made or rescinded any
express or deemed election relating to Taxes, settled or compromised any claim, action, suit
litigation, proceeding, arbitration, investigation, audit or controversy relating to Taxes,
(f) incurred any Indebtedness other than in the ordinary course of business consistent with past
practices, or (g) suffered any Schein Material Adverse Effect. Since September 26, 2009, except as
set forth on Schedule 3.7, HSI and its Subsidiaries have not increased any wages, salaries,
bonuses or any other direct or indirect cash compensation received by any employee or consultant
whose duties are primarily related to the Contributed Schein Vet Business and whose current or
committed annual rate of cash compensation (including bonuses and commissions) exceeds $100,000.
From the Balance Sheet Date until the date of this Agreement, except as set forth on
Schedule 3.7, HSI and its Subsidiaries have complied with the covenants set forth in
Sections 8.2(b)(x), (xi) and (xii) of this Agreement.

     3.8 Taxes.

          (a) The representations set forth in this Section 3.8 are subject to the qualifications and
disclosures set forth on Schedule 3.8.

               (i) None of the Contributed Assets is “tax exempt use property” within the meaning of
Section 168(h) of the Code. None of the Contributed Assets is a lease made pursuant to
Section 168(f)(8) of the Internal Revenue Code of 1954. No audits or other similar proceedings are
pending or have been asserted in writing with respect to any Taxes due with respect to the
Contributed Assets or the Assumed Liabilities. In respect of the Contributed Assets and the
Assumed Liabilities, HSI, NLS and MergerSub have timely paid all Taxes owed by such companies and
have made adequate provision for any Taxes that are not yet due and payable for all taxable periods
ending on or before the Closing Date. In respect of the Contributed Assets and the Assumed
Liabilities, HSI, NLS and MergerSub have filed all Tax Returns required to have been filed on or
before the date hereof, all Taxes shown to be due on the Tax Returns referred to in this sentence
have been timely paid and all such Tax Returns were correct and complete in all material respects.
Schedule 3.8 sets forth the jurisdictions in which HSI (in respect of the Contributed
Assets), NLS and MergerSub file Tax Returns and no written claim has been made by any Governmental
Authority in a jurisdiction where HSI (in respect of the Contributed Assets), NLS or MergerSub,
whichever applicable, does not file Tax Returns that it is required to file Tax Returns in that
jurisdiction. There are no material Tax Liens pending or, to the knowledge of HSI, NLS and
MergerSub, threatened against HSI, NLS, MergerSub or their assets or property (including, without
limitation, the Contributed Assets), other than Permitted Liens. Neither HSI, NLS, nor MergerSub
is a “foreign person” within the meaning of Section 1445(b)(2) of the Code; at the Closing, HSI,
NLS, and MergerSub shall provide to Butler Holding and OHCP, as applicable, certificates to that
effect that comply with the provisions of the Treasury Regulations under Sections 897 and 1445 of
the Code. Notwithstanding anything herein to the contrary, and for the avoidance of doubt, no
representation is made in this Section 3.8(b) with respect to any Taxes to the extent those Taxes

13

 

result from (i) the transactions contemplated herein or in any of the other Transaction
Documents or (ii)  Butler Holding or BAHS ceasing to utilize the LIFO method of accounting.

     3.9 Personal Property. Except as set forth on Schedule 3.9, HSI is the record
owner of the Vedco Interests, free and clear of all Liens, other than Permitted Liens. HSI and
NLS, as applicable, have good title to or a valid leasehold, license or other similar interest in
the Tangible Property included in the Contributed Assets, free and clear of all Liens, except for
Permitted Liens. The Tangible Property included in the Contributed Assets is in adequate condition
to conduct the Contributed Schein Vet Business as the same is currently conducted, normal wear and
tear excepted, has received continued repair and replacement in accordance with past practice and
is suitable for its current use. To the knowledge of HSI, such Tangible Property is free of any
material structural or engineering defects.

     3.10 Real Property.

          (a) None of the Contributed Assets constitutes real property owned by HSI or NLS.

          (b) Schedule 3.10(b) describes each interest in real property leased by HSI and its
Subsidiaries with respect to the Contributed Schein Vet Business, including the lessor of such
leased property, and identifies each lease or any other agreement under which such property is
leased (collectively, the “HSI Real Property Leases,” and the real property subject to such HSI
Real Property Leases being herein called the “HSI Leased Premises”). HSI and each of its
Subsidiaries enjoys peaceful and quiet possession of the HSI Leased Premises and neither HSI nor
NLS has received any written notice from any landlord under any HSI Real Property Lease asserting
the existence of a material default under any HSI Real Property Lease (or the existence of any
condition which after the passage of time or the giving of notice or both would constitute a
default of or breach under any HSI Real Property Lease) or been informed in writing that the lessor
under any HSI Real Property Lease has taken action or, to the knowledge of HSI, threatened to
terminate the HSI Real Property Lease before the expiration date specified in the HSI Real Property
Lease. Except as set forth on Schedule 3.10(b), the transactions contemplated by this
Agreement or any other Transaction Document will not be the basis for any lessor under a HSI Real
Property Lease to terminate its HSI Real Property Lease prior to the expiration date of the HSI
Real Property Lease. The HSI Leased Premises, the condition thereof, the purposes for which such
HSI Leased Premises are used and the activities of HSI with respect to the Contributed Schein Vet
Business therein, conform in all material respects with Applicable Laws (except Environmental Laws,
as to which only Section 3.21 applies) and all insurance requirements and restrictive covenants
affecting the HSI Leased Premises. The HSI Leased Premises have adequate electric and other
utility services for the operations conducted therein by HSI with respect to the Contributed Schein
Vet Business. There are no “put” or other similar obligations requiring HSI to purchase or lease
any real property or facilities with respect to the Contributed Schein Vet Business. Except as set
forth on Schedule 3.10(b), there are no security deposits under the HSI Real Property
Leases and no security deposit or portion thereof deposited with respect to any Real Property Lease
has been applied in respect of a breach of or default under such Real Property Lease. Except as
set forth on Schedule 3.10(b), none of the HSI Real Property Leases contains any “change of
control” provisions triggered by the consummation of the transactions contemplated by this
Agreement or any other Transaction Document.

14

 

          (c) Except as set forth on Schedule 3.10(c), the HSI Leased Premises include all of
the land, buildings, structures and other improvements used by HSI and its Subsidiaries in the
conduct of Contributed Schein Vet Business.

          (d) HSI Improvements are in good condition and repair and sufficient for the operation of the
Contributed Schein Vet Business.

          (e) There are no leases, subleases, licenses or other agreements granting to any Person other
than HSI or its Subsidiaries any right to the possession, use, occupancy or enjoyment of the HSI
Leased Premises or any portion thereof (other than parking and other common areas used by other
tenants).

          (f) HSI and each of its Subsidiaries holds its leasehold interest in the HSI Leased Premises
(including each of the HSI Improvements) free and clear of all Liens, except for Permitted Liens.

          (g) To the knowledge of HSI, there are no condemnation Proceedings pending or, to the
knowledge of HSI, threatened with respect to all or any part of the HSI Leased Premises.

          (h) There are no outstanding leasing commissions with respect to the HSI Real Property Leases
and all real estate Taxes now and heretofore due or payable with regard to the HSI Leased Premises
have been paid. There is no proposed or pending imposition of any special or other assessments for
public betterments or otherwise, affecting the HSI Leased Premises.

     3.11 Intellectual Property.

          (a) Schedule 3.11(a) hereto contains a list of all material Business Intellectual
Property included in clauses (i), (ii) (iii), (iv) and (vi) of the definition of Intellectual
Property which HSI or any of its Subsidiaries owns and has registered with a Governmental Authority
or other registrar, or with respect to which HSI or any of its Subsidiaries has filed an
application for such a registration. Each of HSI and its Subsidiaries has taken all necessary
actions with the appropriate Governmental Authority to maintain each such registration of Business
Intellectual Property owned by HSI or such Subsidiary and registered with a Governmental Authority,
and such Business Intellectual Property is subsisting and unexpired. Schedule 3.11(a) also
contains a list of all IP Licenses used primarily or exclusively in the Contributed Schein Vet
Business.

          (b) Except as set forth on Schedule 3.11(b), (i) neither HSI nor any of its
Subsidiaries is violating, infringing or misappropriating any Intellectual Property of any other
Person, and no Proceedings have been instituted or, to HSI’s knowledge, threatened, nor, to HSI’s
knowledge, has a communication been received alleging any present or past violation, infringement
or misappropriation, and (ii) to HSI’s knowledge, no third party is violating, infringing or
misappropriating any Business Intellectual Property, nor is there any Proceeding which is pending
or threatened, that challenges the rights of HSI or NLS in respect of any Business Intellectual
Property owned by HSI, NLS or any of its Subsidiaries.

15

 

          (c) Each of HSI and its Subsidiaries has taken all commercially reasonable precautions to
protect the secrecy and confidentiality of its trade secrets and other proprietary Business
Intellectual Property.

          (d) Either HSI or one of its Subsidiaries (i) owns, (ii) otherwise has the right pursuant to a
valid license, sublicense or other agreement to, or (iii) has public domain or other legal access
without the need for a license, lease or consent of any third party to, the Business Intellectual
Property. HSI’s and NLS’s rights in and to the Business Intellectual Property are free and clear
of all Liens, other than Permitted Liens. Except as set forth on Schedule 3.11(d), the
execution and delivery of this Agreement and the performance of the obligations hereunder will not
result in the default under or require consent of any other Person in respect of any IP License or
otherwise result in the loss or diminution of any rights of HSI or its Subsidiaries in or to the
Business Intellectual Property.

          (e) HSI’s and its Subsidiaries’ practices are and have always been in compliance in all
material respects with (i) their then current privacy policies and (ii) their customers’ or any
other party’s privacy policies when required to do so by contract. Neither HSI nor its
Subsidiaries has received a notice of noncompliance relating to its actions relevant to this
Section 3.11(e).

     3.12 Material Contracts. Schedule 3.12 hereto sets forth for HSI and its Subsidiaries
a true, complete and correct list of all of the following Contracts in respect of the Contributed
Schein Vet Business, except those which will be terminated at or prior to the Closing:

without limitation, agreements containing covenants not to compete, non-disclosure or
non-solicitation Contracts or any Contract granting a party thereto exclusive rights;

          (c) Contracts between HSI or NLS and their top twenty (20) vendors based on the aggregate

          (n) any Contract containing any covenant limiting the freedom of HSI or any of its
Subsidiaries or any of their present or future Affiliates with respect to the Contributed Schein
Vet Business to engage in any line of business or in any geographic territory or to compete with

     8.3 Exclusivity. From the date of this Agreement until the Closing Date or the earlier

53

 

          (a) HSI will not, directly or indirectly, solicit any competing offers for the acquisition or
sale of the Contributed Schein Vet Business or any substantial portion of the Contributed Assets,
or negotiate or discuss with any third party with respect to any offer or indication of interest
with respect to any such acquisition or sale.

          (b) Each of Burns, Oak Hill, BAHS and Butler Holding agrees not to, directly or indirectly,
solicit any competing offers for the acquisition of Butler Holding or any of its Subsidiaries, the
sale of any of the shares of membership interests in Butler Holding or any of its Subsidiaries or
the sale of all or a substantial portion of the assets or business of Butler Holding or any of its
Subsidiaries, or negotiate or discuss with any third party with respect to any offer or indication
of interest with respect to any such acquisition or sale.

     8.4 Consents and Approvals. From the date of this Agreement until the Closing Date or the
earlier termination of this Agreement, the parties shall cooperate and use all reasonable efforts

required, by Applicable Law or regulations or otherwise, to obtain, and (b) all consents and
approvals as the parties may agree to obtain.

     8.5 Employees and Employee Benefits.

          (a) Prior to the Closing Date, BAHS shall make an offer of employment, to be effective as of
the Closing Date (or, with respect to employees on approved leave of absence or disability leave,
at the conclusion of such leave), to each employee whose duties are primarily or exclusively
related to the Contributed Schein Vet Business (“Vet Business Employee”). Offers of employment to
such employees shall be on the same or substantially the same terms in aggregate and conditions of
employment with respect to wages, salary, commission, eligibility for benefits and position
applicable to each such employee immediately prior to the Closing Date. Employees who
affirmatively accept BAHS’s offer of employment and commence working for BAHS on the Closing Date
(or, if later, on the date the employee’s approved leave of absence terminates or the employee
returns from disability) are hereinafter referred to as “Transferred Employees” and BAHS and its
Affiliates shall ensure that each Transferred Employee shall receive credit for all service or
employment recognized in accordance with each such employee’s “seniority date” by HSI and
NLS prior to the Closing Date for purposes of eligibility, vesting and the calculation
of benefits (but not for the accrual of benefits under any defined benefit plan or for the
calculation of or vesting of any benefits under any equity compensation plan) under any employee
benefit plan or arrangement, including any severance plan, sick pay plan, vacation, personal or
floating day policy, cash incentive awards based in whole or in part on service, or
other program continued, established, maintained or contributed to by BAHS or any of its Affiliates
under which such Transferred Employee may be eligible to participate on and after the Closing Date;
provided, however,
that for purposes of service awards, each Transferred Employee shall
receive such credit based upon such employee’s “service
date” recognized by HSI; and provided further,
that such crediting of service shall not operate to duplicate
any benefit.

          (b) As of the Closing Date, BAHS shall cause any medical or dental plan established or
maintained by BAHS or its Affiliates after the Closing Date (such plans, “BAHS’s Welfare Plans”) to
waive any pre-existing condition exclusions, evidence of insurability provisions or waiting periods
(except to the extent that such exclusions would have then applied

54

 

or waiting periods were not satisfied under HSI’s or its Affiliate’s health plans) or any
similar provisions with respect to Transferred Employees (and their dependents or other
beneficiaries) after the Closing Date, provided such Transferred Employees (and their
dependents or other beneficiaries) timely enroll for coverage under BAHS’s Welfare Plans upon
becoming employed with BAHS or an Affiliate of BAHS. For purposes of computing deductible amounts
under BAHS’s Welfare Plans, expenses and claims incurred by a Transferred Employee (or a
beneficiary thereof) under a welfare plan of HSI or any Affiliate for the year in which the Closing
occurs shall be credited or recognized under BAHS’s Welfare Plans to the extent such plans would
have credited or recognized such expenses or claims if the individual had been covered under BAHS’s
Welfare Plans at the time the expenses or claims were incurred.

          (c) In any termination or layoff of any Transferred Employee by BAHS after the Closing Date,
BAHS shall fully comply, if applicable, with all Applicable Laws. BAHS will bear the cost of
compliance with (or failure to comply with) any such laws after the Closing.

          (d) HSI and its Affiliates shall be responsible for any legally mandated continuation of
health care coverage for employees who are not Transferred Employees and/or their dependents who
have a loss of health care coverage due to a qualifying event which occurs at or before the Closing
Date, and for satisfaction of any related notice requirements with respect to such employees and
their dependents, and BAHS and its Affiliates shall be responsible for any legally mandated
continuation of health care coverage for Transferred Employees and/or their dependents who have a
loss of health care coverage due to a qualifying event which occurs on and after the Closing Date,
and for satisfaction of any related notice requirements.

          (e) BAHS shall be responsible for any claims by any Transferred Employee (and any beneficiary
thereof) for any liabilities for severance pay, notice pay, accrued vacation pay, workers’
compensation and similar laws or under COBRA or in connection with any other liability related to
such person’s employment with BAHS or an Affiliate of BAHS or arising out of a termination of such
person’s employment with BAHS or an Affiliate of BAHS on and after the Closing Date. BAHS shall
not be responsible for any unpaid and unused vacation, sick, personal and floating days accrued by
each Transferred Employee as of the Closing Date. Any severance pay or notice pay (including but
not limited to liability under WARN) with respect to a Vet Business Employee as a result of a
termination of employment with HSI, NLS, BAHS, or any Affiliate of any of them occurring during the
period beginning on the Closing Date and ending on the date that is the nine month anniversary of
the Closing Date shall be a liability of BAHS, and neither HSI nor any Subsidiary of HSI shall have
any liability or obligation therefor. Severance to Transferred Employees shall be paid according
to the terms of the BAHS severance pay plan described on Schedule 8.5(e).

          (f) Effective as of the Closing Date, the Transferred Employees who have vested account
balances in the Henry Schein, Inc. 401(k) Savings Plan or any other 401(k) plan maintained by HSI
or any Affiliate thereof (collectively, the “HSI 401(k) Plan”) shall be entitled to receive
distributions of their vested account balances in accordance with, and subject to, the terms of the
HSI 401(k) Plan and shall be permitted to roll over their eligible rollover distributions, which
may include promissory notes evidencing outstanding participant loans (“Loans”) under the HSI
401(k) Plan, to any 401(k) plan qualified under Section 401(a) of the Code established or
maintained by BAHS (or an Affiliate thereof) (the “Butler 401(k) Plan”) in

55

 

which they participate, provided that such plan shall be amended, as necessary, to
accept rollover contributions and to provide for the assumption and continuation of the rolled over
Loans on the same terms and conditions as in effect under the HSI 401(k) Plan immediately prior to
the rollover.

          (g) HSI, NLS and BAHS shall use the alternate procedure provided for in Section 5 of Internal
Revenue Service Revenue Procedure 2004-53 with regard to the preparation and filing of Forms W-2
and other employment tax forms relating to Transferred Employees.

          (h) BAHS shall be responsible for the payment of all salary and wages, employment and payroll
taxes, and related withholding, with respect to each Vet Business Employee for any payroll period
ending on a date following the Closing Date. HSI shall reimburse BAHS for the aggregate amount of
salary and wages, and amounts equal to any additional employment and payroll taxes with respect
to Vet Business Employees for the period beginning on the first day of the applicable payroll
period in which the Closing Date occurs and ending at the close of business on the Closing Date.
Additionally, BAHS shall be responsible for the payment of unpaid bonuses, in amounts to be
determined by HSI in its sole discretion, in respect of calendar year 2009, payable to Vet Business
Employees following the Closing Date, all employment and payroll taxes thereon, and related
withholding. HSI shall reimburse BAHS for the aggregate amount of such bonuses, and amounts equal
to any additional employment and payroll taxes, and, if applicable, any employer match contributed to the Butler
401(k) Plan in respect of such bonuses. Reimbursements under this Section 8.5(h) shall be made
within 15 days following receipt by HSI of documentation of the applicable payment(s) for which
such reimbursement is sought. HSI shall be entitled to all of the Tax deductions relating to
reimbursements under this Section 8.5(h).

     8.6 Reasonable Efforts. From the date of this Agreement until the Closing Date or the earlier
termination of this Agreement, the parties agree to act in good faith and use commercially
reasonable efforts to (a) take all actions and to do all things necessary to consummate the
transactions contemplated by this Agreement and the other Transaction Documents, including without
limitation, to obtain the satisfaction of the conditions specified in this Agreement necessary to
consummate the transactions contemplated hereby and (b) file or supply, or cause to be filed or
supplied, all applications, and information required to be filed or supplied by HSI, Butler Holding
or any of their Subsidiaries pursuant to any Applicable Law in connection with this Agreement or
the other Transaction Documents, the contribution and transfer of the Contributed Assets to Butler

and NLS’s ownership of the Contributed Schein Vet Business prior to the Closing including, without
limitation, the preparation of Tax Returns and the determination of the Tax basis of the
Contributed Assets. In the event of any litigation or threatened litigation between the parties

for reasons qualifying the termination as “employment losses” under the WARN Act and the date of

consummated hereby.

          (b) Butler Holding shall pay all applicable sales and transfer Taxes and filing, recording
(mortgage or otherwise), registration, stamp, documentary, collateral assignment and other similar
Taxes and fees (the “Transfer Taxes”) resulting from the transactions contemplated by this

to such Transfer Taxes.

          (c) HSI, MergerSub and OHCP intend that the Merger qualify as a reorganization within the
meaning of Section 368(a) of the Code and agree to file all Tax Returns in a manner consistent with
the treatment of the Merger as such a reorganization. Following the Merger, MergerSub shall not
take, and HSI shall not cause MergerSub to take, any action (other than any action consented to or
caused by Oak Hill or any action required by the Transaction Documents) that will cause the Merger
to not qualify as a reorganization within the meaning of Section 368(a) of the Code. Neither HSI
nor MergerSub has any present plan or intention to take any action following the Closing that would
cause a discontinuance of the historic business of WA Butler or a discontinuance of the use of a

     8.15 Financing Cooperation. The parties hereto shall use their commercially reasonable
efforts to, and shall cause their respective Subsidiaries to, reasonably cooperate with Butler
Holding and its Subsidiaries and their lenders in connection with Butler Holding and its
Subsidiaries obtaining the financing on the terms provided for in the Commitment Letter (the
“Financing”), including (i) making representatives of all parties hereto available at reasonable
times in connection with the syndication of any debt financing and (ii) assisting Butler Holding
and its Subsidiaries in obtaining all customary waivers, estoppels, approvals, opinions, transfer
documents and consents from counterparties to the HSI Material Contracts and the Butler Material
Contracts. Butler Holding and its Subsidiaries will use their commercially reasonable efforts to
perform all of its obligations under the Commitment Letter and satisfy all conditions precedent to
the funding thereunder. Butler Holding and its Subsidiaries shall not amend the Commitment Letter
in any manner that shall make the consummation of the transactions contemplated hereby materially
less likely to occur. In the event that the Financing is not available to consummate the
transactions contemplated by this Agreement, the parties hereto shall, and shall cause their
respective Subsidiaries to, use commercially reasonable efforts to obtain alternative financing on
terms, taken in the aggregate, that are, in the reasonable judgment of Butler Holding and HSI, no
less favorable to Butler Holding and its Subsidiaries than those set forth in the Commitment Letter
(the “Alternative Financing”). Subject to the Shared Expenses Agreement, nothing in this Section
8.15 shall require any party other than Butler Holding, BAHS and any Subsidiary of Butler Holding
and BAHS to provide any credit enhancement or other credit support (including, without limitation,
guaranty, indemnification or collateral) or incur a material cost in connection with the Financing
or Alternative Financing.

     8.16 Transition Services. From and after the Closing, at BAHS’s request, HSI shall provide
substantially the same services and other assistance to the Contributed Schein Vet Business as may
be reasonably necessary to operate the Contributed Schein Vet Business after the Closing (the
“Post-Closing Services”). Butler Holding and BAHS shall reimburse HSI and its Subsidiaries for all
direct costs and expenses and all allocated costs and expenses (allocated in the same manner and
methodology used to derive the
Core Vet Financials for the twelve (12) month period ended September
26, 2009, with such modifications as the parties may mutually agree are reasonably necessary to
reflect the operations of the Contributed Schein Vet Business after
the Closing) incurred in connection with the
provision of such Post-Closing Services within twenty (20) days after invoicing (such invoices to
include reasonable detail of the costs and expenses for the Post-Closing Services provided).
Butler Holding may terminate any Post-Closing Service upon at least thirty (30) days prior written
notice to HSI. HSI and its Subsidiaries shall not be under any obligation to provide Post-Closing
Services after the date that is ninety (90) days following the Closing Date.

     8.17 Intellectual Property. HSI agrees to provide a non-exclusive, non-transferable,
non-sublicensable, royalty-free license or sub-license to Butler Holding and its Subsidiaries to
use Excluded IP solely for use in the Vet Business within North  America, South America and Central America on terms
and conditions reasonably acceptable to HSI and Butler Holding; provided, however,
that (a) HSI shall not be obligated to provide any such license or sub-license if it would be in
violation of any Applicable Law or Contract and (b) HSI shall not be under any obligation to obtain
any third party consents or incur any additional costs or expenses in connection therewith.

     8.18
Post-Closing Receivables. From and after the Closing Date, if HSI receives payment (including by set-off) for (i) any
accounts receivable included as HSI Current Assets in the final determination of HSI Closing
Working Capital as of the Closing Date or (ii)  rebates receivable to the extent related

59

 

to the Contributed Schein Vet Business and allocated in a manner consistent with
HSI’s past practices, HSI shall, as promptly as practicable, remit such payment to BAHS.

     8.19 Waiver
of Consents. The parties acknowledge that certain Contracts included in
the Contributed Assets and certain Contracts of BAHS by their terms
require consent with respect to the transactions contemplated hereby.
HSI and Butler Holding agree to waive any requirements to obtain
consents for such Contracts prior to
Closing and shall  cooperate with each other  and use  commercially reasonable efforts
to obtain such consents before and after the Closing as they shall mutually
agree.
 Butler Holding shall assume any and all Liabilities related thereto, and indemnify and hold harmless HSI and NLS
from and against any and all Liabilities related thereto or arising
therefrom.

     8.20 HSI Payables. Butler Holding shall pay to HSI an amount equal to
$6,700,000 within thirty (30) days following the Closing Date (the
“HSI Payable”).

     8.21 Darby Guaranty. Darby hereby unconditionally guarantees to HSI the full prompt payment
and punctual performance by Burns of any and all obligations of Burns arising under this Agreement,
including, without limitation, those obligations arising under Article 10. The liability of Darby
hereunder shall not be conditioned or contingent upon pursuit by HSI or any other HSI Indemnified
Party of any remedies either may have against Burns with respect to this Agreement. No exercise or
nonexercise by HSI or any other HSI Indemnified Party of any right given to it hereunder, and no
change, impairment or suspension of any right or remedy of HSI or any other HSI Indemnified Party
hereunder, shall in any way affect Darby’s obligations hereunder. Darby acknowledges and agrees
that this Section 8.21 is a guaranty of payment and performance, and not merely of collectability,
and constitutes a direct obligation of Darby.

     8.22 Insurance.

          (a) On or prior to the Closing Date, Butler Holding shall provide evidence to HSI that Butler
Holding, at the expense of Butler Holding,
(to be paid following the Closing Date),
obtained
a six year tail for its director and officer liability insurance
policy. HSI and Butler Holding shall mutually determine an
appropriate insurance program for BAHS from and after the Closing
Date.

          (b) From and after the Closing Date, HSI will provide that WA Butler, Butler Holding and BAHS
shall be insured under the HSI director and officer liability
insurance policy. HSI shall allocate and charge Butler Holding
for such insurance in a manner consistent with HSI’s past practices with respect to its allocations
of such charges to NLS. Payment for such charges shall be due
within twenty (20) days after invoicing therefor.

          8.23 Bank Accounts; Outstanding Checks. On or prior to Closing, Butler Holding
and BAHS shall cooperate with HSI and NLS to cause the bank accounts of
NLS (with no cash) to be transferred to or merged into the bank accounts of BAHS such that any outstanding checks made by NLS which are outstanding as of the Closing
shall be funded by a bank account of BAHS. If such bank accounts are not transferred on or prior to Closing, then any obligations
for checks made by NLS  but not cashed as of the  Closing (provided that such underlying liability or obligation is included
as HSI Current Liabilities in the final determination of the HSI Closing Working Capital) that are satisfied by NLS shall be
treated as a Current Asset of the Contributed Schein Vet Business for purposes the final determination of HSI Closing Working Capital
pursuant to Section 2.4.

ARTICLE 10

SURVIVAL; INDEMNIFICATION

     10.1 Survival. The parties agree that the representations, warranties and covenants
(requiring performance prior to Closing) contained in this Agreement shall survive the Closing
until the date that is fifteen (15) months after the Closing, except that the Specified
Representations, 5.1 (Organization, Power and Standing), 5.2 (Power and Authority), 5.5 (Brokers),
5.8 (No Other Representations or Warranties), 6.1 (Organization, Power and Standing), 6.2
(Capitalization), 6.3 (Power and Authority), 6.6 (Brokers), 6.8 (No other Representations or
Warranties), 6.10 (Business of WA Butler), 6.11 (Taxes), 7.1 (Power and Authority), 7.4 (Brokers),
and 7.6 (No Other Representations or Warranties) shall survive until the expiration of the
applicable statute of limitations, and (b) the representations and warranties contained in 3.21
(Compliance with Environmental Laws) and 4.21 (Compliance with Environmental Laws) shall survive
until the three (3) year anniversary of the Closing. The applicable date of termination for the
survival period of each representation or warranty is sometimes referred to herein as its “Cut-Off
Date”. No claim for indemnification hereunder for breach of any representation or warranty may be
brought after its applicable Cut-Off Date, except for claims of which the Indemnifying Party has
been notified in writing with reasonable specificity by the Indemnified Party prior to its Cut-Off
Date. All covenants and agreements to be performed after the Closing contained in this Agreement
shall survive the Closing in accordance with their terms.

     10.2 Indemnification of the Butler Indemnified Parties. Subject to the other terms of this
Article 10, from and after the Closing, HSI agrees to indemnify each of the Butler Holding
Members, and each of their respective officers, directors, employees, partners, members, agents and
Affiliates (the “Butler Indemnified Parties”) and hold them harmless against and in respect of any
and all damages, losses, expenses, costs, obligations and liabilities, including without limitation
reasonable attorneys’ fees (collectively, “Losses”), which arise or result from (a) any breach of
any of the representations or warranties made by HSI contained in Article 3 of this
Agreement or contained in any other Transaction Document delivered by HSI to Butler Holding at the
Closing pursuant to this Agreement, (b) the failure of HSI to perform any of its covenants or
agreements contained herein to be performed after the Closing, (c) the failure of HSI to perform
any agreement or covenant contained herein which by its terms is required to be fully performed
prior to the Closing, (d) the Excluded Assets, and (e) the Excluded Liabilities. HSI’s
indemnification obligations under this Agreement, however, shall be subject to the following
limitations and conditions:

               (i) For purposes of this Section 10.2, Losses shall include any diminution in the value of the
direct or indirect economic interest of the Butler Holding Members in Butler Holding. If an
indemnifiable Loss under this Section 10.2 is suffered directly by a Butler Holding Member, the
indemnification payment in respect of such Loss shall be paid by HSI in respect of the full amount
of such direct Loss. If an indemnifiable Loss under this Section 10.2 is suffered directly by
Butler Holding, BAHS or any of their Subsidiaries (as opposed to directly suffered by another
Butler Indemnified Party), the indemnification payment in respect of such Loss shall be paid
directly to the Butler Holding Members and the determination of the amount of such Loss to each
Butler Holding Member shall reflect the direct

63

 

and indirect percentage interest of such Butler Holding Member in Butler Holding immediately
following the Closing.

               (ii) HSI shall have no indemnification obligation under Section 10.2(a) unless, and only to
the extent that, the cumulative amount of Losses incurred by the Butler Indemnified Parties exceeds
$2,000,000; provided, however, that this limitation shall not apply to the
Specified Representations or any agreements or covenants contained herein.

               (iii) HSI’s cumulative liability for indemnification payments under Sections 10.2(a) shall not
exceed, in the aggregate, $15,000,000; provided, however, that this limitation
shall not apply to the Specified Representations or any agreements or covenants contained herein.

               (iv) HSI shall have no indemnification obligation with respect to Losses for any breach of the
representations and warranties contained in Section 3.21, except to the extent such Losses
represent amounts actually incurred by the Butler Indemnified Parties for the performance of
investigation or remedial action, or the payment of any fine, penalty or damage award, in each case
required by an Environmental Law or ordered by any Governmental Authority with jurisdiction over
the matter, or in defense of or reasonable settlement of an Environmental Claim asserted by any
Governmental Authority or third party in accordance with Section 10.8(b).

               (v) No claim for indemnification in respect of the Schein Pre-Closing Taxes shall be made
unless, and to the extent that, the amount of unpaid Schein Pre-Closing Taxes exceeds the aggregate
amount of Taxes which are included as HSI Current Liabilities in the final determination of the HSI
Closing Working Capital.

               (vi) The final determination of the Closing Working Capital at Closing shall be made pursuant
to Article 2, and no claim under this Article 10 shall be made against HSI in
respect of the determination of the components of HSI Closing Working Capital other than a claim
for breach of Article 2.

               (vii) [Intentionally Omitted.]

               (viii) For purposes of HSI’s indemnification obligations contained in this Section 10.2 with
respect to the representations and warranties contained in Article 3 with respect to MergerSub (the
“MergerSub Indemnity”) (a) OHCP shall be the only Butler Indemnified Party entitled to
indemnification; (b) all indemnification payments in respect of the MergerSub Indemnity shall be
paid by HSI directly to OHCP and (c) the MergerSub Indemnity shall not be subject to any cap or
basket hereunder.

               (ix) For purposes of the indemnification provisions contained in this Section 10.2, all
materiality qualifications in respect of the representations and warranties contained herein (other
than the representations and warranties contained in Sections 3.6 (Financial Statements) and 3.7(g)
(Absence of Certain Changes)) shall be disregarded; it is understood, however, that where a
representation or warranty requires a list of certain items on a

64

 

Schedule to this Agreement (e.g., the Material Contracts Schedule), it is not the intent of
the parties that this clause (ix) would broaden the scope of the disclosures required to be set
forth on such Schedule.

               In determining the foregoing thresholds and in otherwise determining the amount of any Losses
for which the Butler Indemnified Parties are entitled to assert a claim for indemnification
hereunder, the amount of any such Losses shall be determined after deducting therefrom the amount
of any insurance proceeds (after giving effect to any applicable deductible or retention) and other
third-party recoveries (net of any costs incurred to obtain such insurance proceeds or recoveries),
in such cases, actually received by the Butler Indemnified Parties or Butler Holding in respect of
such Losses (which proceeds and recoveries the Butler Indemnified Parties and Butler Holding agree
to use diligent efforts to obtain). If an indemnification payment is received by a Butler
Indemnified Party, and such Butler Indemnified Party later receives insurance proceeds or other
third-party recoveries in respect of such Losses, such Butler Indemnified Party shall immediately
pay to HSI a sum equal to the lesser of (y) the actual amount of such insurance proceeds and other
third-party recoveries (net of any costs incurred to obtain such insurance proceeds or recoveries)
or (z) the actual amount of the indemnification payment previously paid by HSI, with respect to
such Losses.

     10.3 Indemnification of the HSI Indemnified Parties by the Butler Group. Subject to the other
terms of this Article 10, from and after the Closing, each member of the Butler Group
severally (based on their respective Indemnification Percentage Interests), and not jointly and
severally, agrees to indemnify HSI, each of its officers, directors, employees, partners, members,
agents and Affiliates (the “HSI Indemnified Parties”) and hold them harmless against and in respect
of any and all Losses, which arise or result from (a) any breach of any of the representations or
warranties contained in Article 4 of this Agreement or contained in any other Transaction
Document delivered by Butler Holding or any of its Subsidiaries to HSI at the Closing pursuant to
this Agreement, (b) the failure of Butler Holding or any of its Subsidiaries to perform any of its
covenants or agreements contained herein to be performed after the Closing, (c) the failure of
Butler Holding or any of its Subsidiaries to perform any agreement or covenant contained herein
which by its terms is required to be fully performed prior to the Closing, and (d) any disputes or
Liabilities involving a holder of any class of Butler Holding Common Shares or any other Equity
Securities issued or outstanding (or alleged to have been issued or outstanding) at any time at or
prior to the Closing arising out of or relating to the transactions contemplated hereby, including,
without limitation, the allocation of any purchase price or redemptions paid hereunder. The Butler
Group’s indemnification obligations pursuant to this Section 10.3, however, shall be subject to the
following limitations and conditions:

               (i) Each member of the Butler Group shall be responsible for its Indemnification Percentage
Interest of any indemnifiable Losses pursuant to this Section 10.3.

               (ii) For purposes of this Section 10.3, Losses shall include any diminution in the value of
the direct or indirect economic interest of HSI in Butler Holding. If an indemnifiable Loss under
this Section 10.3 is suffered directly by an HSI Indemnified Party, the indemnification payment in
respect of such Loss shall be paid by the Butler Group in respect of the full amount of such direct
Loss. If an indemnifiable Loss under this Section 10.3 is suffered directly by Butler Holding,
BAHS or any of their Subsidiaries (as opposed to directly suffered by

65

 

another Butler Indemnified Party), the indemnification payment in respect of such Loss shall
be paid directly to HSI and the determination of the amount of such Loss to HSI shall reflect the
direct and indirect percentage interest of HSI in Butler Holding immediately following the Closing.

               (iii) The Butler Group shall have no indemnification obligation under Section 10.3(a) unless,
and only to the extent that, the cumulative amount of Losses incurred by HSI Indemnified Parties
for any claims pursuant to this Section 10.3 exceeds $2,000,000; provided, however,
that this limitation shall not apply to the Specified Representations, or any agreements or
covenants contained herein.

               (iv) The Butler Group’s cumulative liability for indemnification payments under Section
10.3(a) shall not exceed, in the aggregate, $20,000,000; provided, however, that
this limitation shall not apply to the Specified Representations, or any agreements or covenants
contained herein.

               (v) The Butler Group shall have no indemnification obligation with respect to Losses for any
breach of the representations and warranties contained in Section 4.21, except to the extent such
Losses represent amounts actually incurred for the performance of investigation or remedial action,
or the payment of any fine, penalty or damage award, in each case required by an Environmental Law
or ordered by any Governmental Authority with jurisdiction over the matter, or in defense of or
reasonable settlement of an Environmental Claim asserted by any Governmental Authority or third
party in accordance with Section 10.8(b).

               (vi) No claim for indemnification in respect of the Butler Holding Pre-Closing Taxes shall be
made unless, and to the extent that, the amount of unpaid Butler Holding Pre-Closing Taxes exceeds
the aggregate amount of Taxes which are included as Butler Holding Current Liabilities in the final
determination of the Butler Holding Closing Working Capital.

               (vii) The final determination of the Butler Holding Closing Working Capital at Closing shall
be made pursuant to Article 2, and no claim under this Article 10 shall be made
against the Butler Group in respect of the determination of the components of Butler Holding
Closing Working Capital at Closing other than a claim for breach of
Article 2.

               (viii) [Intentionally Omitted.]

               (ix) For purposes of the indemnification provisions contained in this Section 10.3, all
materiality qualifications in respect of the representations and warranties contained herein (other
than the representations and warranties contained in Sections 4.6 (Financial Statements) and 4.7(g)
(Absence of Certain Changes)) shall be disregarded; it is understood, however, that where a
representation or warranty requires a list of certain items on a Schedule to this Agreement (e.g.,
the Material Contracts Schedule), it is not the intent of the parties that this clause (ix) would
broaden the scope of the disclosures required to be set forth on such Schedule.

66

 

In determining the foregoing thresholds and in otherwise determining the amount of any Losses for
which an HSI Indemnified Party is entitled to assert a claim for indemnification hereunder, the
amount of any such Losses shall be determined after deducting therefrom the amount of any insurance
proceeds (after giving effect to any applicable deductible or retention) and other third-party
recoveries (net of any costs incurred to obtain such insurance proceeds or recoveries), in such
cases, actually received by such HSI Indemnified Party in respect of such Losses (which proceeds
and recoveries the HSI Indemnified Parties agree to use diligent efforts to obtain). If an
indemnification payment is received by an HSI Indemnified Party, and such HSI Indemnified Party
later receives insurance proceeds or other third-party recoveries in respect of such Losses, such
HSI Indemnified Party shall immediately pay to the Butler Group (in proportion to their respective
Indemnification Percentage Interests) a sum equal to the lesser of (y) the actual amount of such
insurance proceeds and other third-party recoveries (net of any costs incurred to obtain such
insurance proceeds or recoveries) or (z) the actual amount of the indemnification payment
previously paid by the Butler Group, with respect to such Losses.

     10.4 Indemnification of HSI by Oak Hill. From and after the Closing, OHCP and OHCM, jointly
and severally, agree to indemnify the HSI Indemnified Parties and hold them harmless against and in
respect of any and all Losses which arise or result from any (a) breach of any of representations
and warranties contained in Article 6 and (b) the failure of OHCP, OHCM or WA Butler to
perform any of their respective covenants or agreements set forth in this Agreement. The indemnity
obligations set forth in this Section 10.4 shall not be subject to any cap or basket hereunder.

     10.5 Indemnification of HSI by Burns. From and after the Closing, Burns agrees to indemnify
the HSI Indemnified Parties and hold them harmless against and in respect of any and all Losses
which arise or result from any (a) breach of any of representations and warranties made by Burns
contained in Article 5 or (b) the failure of Burns to perform any of its covenants or
agreements set forth in this Agreement. The indemnity obligations set forth in this Section 10.5
shall not be subject to any cap or basket hereunder.

     10.6 Indemnification of HSI by Management Members. From and after the Closing, each of the
Management Members agree to indemnify the HSI Indemnified Parties and hold them harmless against
and in respect of any and all Losses which arise or result from any (a) breach of any of
representations and warranties made by such Management Member contained in Article 7 or
(b) the failure of such Managing Member to perform any of their respective covenants or agreements
set forth in this Agreement. The indemnity obligations set forth in this Section 10.6 shall not be
subject to any cap or basket hereunder.

     10.7 Indemnification of HSI by Butler Holding and BAHS. From and after the Closing, Butler
Holding and BAHS, jointly and severally, shall, and shall cause each of their respective
Subsidiaries to, indemnify the HSI Indemnified Parties and hold them harmless against and in
respect of any and all Losses based on, attributable to, arising from or relating to (i) the
Assumed Liabilities, (i) the Liabilities under Sections 8.5(e) and (h), and (iii) the ownership and
operation of the Schein Vet Business after the Closing; provided, however, that
neither Butler Holding and BAHS shall be required to indemnify the HSI Indemnified Parties for any
Losses for which HSI is required to indemnify the Butler Holding Members pursuant to

67

 

Section 10.2. The indemnity obligations set forth in this Section 10.7 shall not be subject
to any cap or basket hereunder.

     10.7A Indemnification of HSI by Butler Holding Members. From and after the Closing, each of the Butler Holding Members (severally, in accordance with their
respective Pre-Closing Percentage Interests) agree to indemnify the HSI Indemnified Parties and hold them harmless against and in
respect of any and all Losses based on or attributable to Taxes of WA Butler or MergerSub in the
taxable year of the Closing Date relating to or arising from the distribution of cash to WA Butler or MergerSub on the Closing Date in accordance with the
Closing Mechanics, determined as if no other relevant transactions occurred other than those set forth on Schedule 1.8. The indemnity obligations set forth in this Section 10.7A shall not be
subject to any cap or basket hereunder and shall expire three (3) months after the expiration of any applicable statute of limitations (or extensions thereof). The Butler Group shall prepare the Tax Returns of WA Butler and the Company for such taxable year. They will provide HSI with a
reasonable opportunity to review drafts of such returns and comment prior to filing, it being understood that the Butler Group shall make the final decision with respect thereto.

     10.8 Procedure for Indemnification.

          (a) Any party making a claim for indemnification hereunder (the “Indemnified Party”) shall
promptly notify the indemnifying party (the “Indemnifying Party”) of the claim in writing,
describing the claim in reasonable detail, the amount thereof, and the basis therefor;
provided, that the failure to provide prompt notice shall not relieve the Indemnifying
Party of its indemnification obligations hereunder, except to the extent that the Indemnifying
Party is actually prejudiced by the failure to give such prompt notice. The party from whom
indemnification is sought shall respond to each such claim within thirty (30) days of receipt of
such notice. No action shall be taken pursuant to the provisions of this Agreement or otherwise by
the Indemnified Party (unless reasonably necessary to protect the rights of the Indemnified Party)
until the expiration of the 30-day response period.

          (b) If a claim for indemnification hereunder is based on a claim by a third party, the
Indemnifying Party shall have the right to assume the entire control of the defense thereof, at its
own expense, including employment of counsel reasonably satisfactory to the Indemnified Party, by
providing written notice to the party seeking indemnification that it will assume the defense of
such claim within thirty (30) days after its receipt of notice in accordance with Section 10.8(a)
above by the Indemnified Party, and, in connection therewith, the Indemnified Party shall cooperate
fully with the Indemnifying Party and make available to the Indemnifying Party all pertinent
information under its control; provided, that the Indemnified Party may participate in any
proceeding with counsel of its choice at its expense; and provided, however, that
the Indemnifying Party shall not be entitled to assume control of the defense if (i) upon petition
by the Indemnified Party, the appropriate court rules that the Indemnifying Party failed or is
failing to vigorously prosecute or defend such claim, (ii) the claim would reasonably be expected
to give rise to Losses which are more than twice the amount indemnifiable by such Indemnifying
Party pursuant to this Article 10 or (iii) the claim is for injunctive or equitable relief
or relates to a criminal prosecution or indictment of Butler Holding or any of its Affiliates (and
the Indemnified Party’s reasonable costs in conducting the defense thereof shall be considered
“Losses”). In the event that the Indemnifying Party assumes the defense, the Indemnifying Party
shall have the right to settle or resolve any such claim by a third party; provided, that
any such settlement or resolution contemplated the Indemnifying Party, shall not be concluded
without the prior written approval of the Indemnified Party, which approval shall not be
unreasonably withheld, delayed or conditioned.

     10.9 Remedies Exclusive. The remedies provided in this Article 10 shall be the
exclusive remedies of the parties hereto after the Closing in connection with the transactions
contemplated by this Agreement, including, without limitation, for any breach or non-performance of
any representation, warranty, covenant or agreement contained herein, except (a) in the case of
fraud and willful misconduct, in which case the harmed party shall have all rights and remedies
under this Agreement and provided by law against the party that committed the fraud or willful
misconduct, (b) any equitable remedies that do not involve the payment of monetary damages and
(c) as set forth in Sections 2.2, 2.3 and 2.4. No party may commence any suit, action or
proceeding against any other party hereto or any of their respective Affiliates with

68

 

respect to the subject matter of this Agreement, whether in contract, tort or otherwise,
except (i) to enforce such party’s express rights under this Article 10, (ii) to bring a
claim for fraud and willful misconduct or (iii) to seek injunctive relief or specific performance
to enforce specifically the terms of this Agreement to the extent permitted by law.

     10.10 Tax Treatment of Indemnity Payments. It is the intention of the parties to treat any
indemnity payment made under this Agreement as a direct or indirect contribution, as an adjustment
to a direct or indirect contribution or as an adjustment to purchase price or other consideration,
as the case may be, for all federal, state, local and foreign Tax purposes, and the parties agree
to file their Tax Returns accordingly and not take any inconsistent position.

     10.11 Indemnification for Disclosures Related to Taxes and Brokers.
Notwithstanding the disclosure of any item on Schedules 4.8 or 6.11 with respect to Taxes, and Schedules 4.20, 5.5 or 6.6 with respect to
brokers, the HSI Indemnified Parties shall be indemnified with respect thereto as if no such disclosure had been set forth on such
Schedule, and the representation and warranty was not so qualified by
such disclosure; provided, however, that in the case of Taxes, this Section 10.11 shall apply only to the extent of
Taxes payable to Taxing authorities with respect to periods (or portions thereof) ending on or prior to the Closing Date).

     10.12 No Consequential or Punitive Damages.
None of the parties hereto shall have any indemnification obligation for consequential damages, punitive or exemplary damages, special
damages or lost profits, except with respect to a claim for such damages by a third party against the party seeking indemnification.

ARTICLE 11

TERMINATION

     11.1 Termination. Notwithstanding anything contained in this Agreement to the contrary, this
Agreement may be terminated prior to the Closing:

          (a) by mutual written consent of HSI and Butler Holding;

          (b) by Butler Holding, if both (i) any of the representations and warranties of HSI set forth in
this Agreement shall not be true and correct to the extent set forth in
Section 9.2(a), or HSI shall have breached or failed to perform any of its
obligations, covenants or agreements under this Agreement to the extent set forth in
Sections 9.2(b), and (ii) such breach, failure or misrepresentation has resulted in a Schein Material Adverse Effect;

          (c) by HSI, if both (i) any of the representations and warranties of Butler Holding, Oak Hill,
Burns or the Management Members set forth in this Agreement shall not be true and correct to the extent set forth in Section 9.3(a), or if Butler Holding, Oak Hill, Burns
or any Managing Members shall have breached or failed to perform any of its
obligations, covenants or agreements under this Agreement to the extent set forth in
Section 9.3(b), and (ii) such breach, failure or misrepresentation has resulted in a Butler Holding Material Adverse Effect;

          (d) by either HSI or Butler Holding, if any Governmental Authority has issued a final and
non-appealable order, decree or ruling permanently restraining, enjoining or otherwise prohibiting
the consummation of the transactions contemplated by this Agreement;

          (e) by either HSI or Butler Holding, if the Closing has not occurred by the Termination Date
or such other date, if any, as HSI and Butler Holding may agree in writing, provided that
the right to terminate this Agreement under this Section 11.1(e) will not be available to any party
whose material breach of this Agreement has been the cause of the failure of the Closing to occur
on or before such date;

     As used herein, the “Termination Date” shall mean March 31, 2010.

69

 

     11.2 Effect of Termination.

          (a) If this Agreement is terminated as provided in Section 11.1 above, this Agreement shall
become null and void and have no further force or effect and the parties shall have no further
obligations hereunder (including, without limitation, for costs and expenses incurred by other
parties in connection with this Agreement and the transactions contemplated hereby), except as
provided below and except that each party shall be liable for its willful breach of the provisions
of this Agreement and the non-breaching party hereto shall be entitled to all rights and remedies
provided by law or equity in respect of such breach.

          (b) The obligations of the parties under Sections 8.1(c) through (f) and the provisions
contained in Sections 12.4 and 12.10 shall survive the termination of this Agreement.

ARTICLE 12

forth in Butler Holding’s records.

     12.2 No Waiver. No failure of any party to exercise and no delay in exercising any right,
power or remedy hereunder shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or remedy hereunder preclude any other or further exercise thereof or
the exercise of any other right, power or remedy hereunder.

     12.3 Amendments and Waivers. This Agreement may be modified, amended or waived only by a
writing signed by HSI and Butler Holding.

     12.4 Choice of Law; Forum; Waiver of Jury Trial. This Agreement and all claims and
controversies hereunder (whether based on contract, tort or any other theory) shall be governed by
and construed in accordance with the internal laws of the state of New York, without regard to the
choice of law provisions thereof. Any proceeding arising out of or relating to this Agreement
shall be brought in the courts of the state of New York sitting exclusively in the County of New
York, State of New York, or, if it has or can acquire jurisdiction, in the United States District
Court for the Southern District of New York. Each party hereby expressly submits to the personal
jurisdiction and venue of such courts as provided above for the purposes thereof and expressly
waives any claim of improper venue and any claim that such courts are an inconvenient forum. Each
party hereby irrevocably consents to the service of process of any of the aforementioned courts in
any such suit, action or proceeding by the mailing of copies thereof by registered or certified
mail, postage prepaid, to the address set forth or referred to in Section 12.1. EACH PARTY HERETO
HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT
OR THE TRANSACTIONS CONTEMPLATED (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY
HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO
ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN
INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS
IN THIS SECTION.

     12.5 Binding Effects and Benefits. No party may assign either this Agreement or any of its
rights or interests, or delegate any of its duties hereunder, in whole or in part, without the

73

 

prior written consent of the other parties. Any attempt to make any such prohibited
assignment without such consent shall be null and void. Subject to the preceding sentences of this
Section 12.5, this Agreement will be binding upon, inure to the benefit of and be enforceable by,
the parties and their respective successors and permitted assigns.

     12.6 Integration; Schedules. This writing, together with the Exhibits and Schedules attached
hereto, the Transaction Documents, and the Confidentiality Agreement, embody the entire agreement
and understanding among the parties with respect to this transaction and supersede all prior
discussions, understandings and agreements concerning the matters covered hereby and thereby.
Information set forth on any Schedule shall be deemed to qualify each other Section of this
Agreement to which such information is applicable (regardless of whether or not such other Section
is qualified by reference to a Schedule), so long as application to such Section is reasonably
apparent on its face from the reading of such disclosure. No information set forth on any Schedule
shall be deemed to broaden in any way the scope of HSI’s or Butler Holding’s representations and
warranties. The inclusion of any item on a Schedule is not evidence of the materiality of such
item for purposes of the Agreement, or that such item is a disclosure required under the Agreement.
No disclosure in any Schedule relating to any possible breach or violation of any agreement, law
or regulation shall be construed as an admission or indication that any such breach or violation
exists or has actually occurred, or shall constitute an admission of liability to any third party.

     12.7 Counterparts. This Agreement may be executed in one or more counterparts, and
counterparts by facsimile, all of which taken together shall constitute one and the same
instrument, and any of the parties hereto may execute this Agreement by signing any such
counterpart.

     12.8 Limitation on Scope of Agreement. If any provision of this Agreement is unenforceable or
illegal, such provision shall be enforced to the fullest extent permitted by law and the remainder
of the Agreement shall remain in full force and effect.

     12.9 Headings. The headings of Articles, Sections, Exhibits and Schedules herein are inserted for convenience of
reference only and shall be ignored in the construction or interpretation hereof.

     12.10 Expenses; Filing Fees. All legal and other costs and expenses incurred in connection
with this Agreement and the transactions contemplated hereby shall be paid by the party incurring
such costs and expenses, except as otherwise expressly provided herein or the Shared Expenses
Agreement. Effective from and after the Closing, Butler Holding will pay as and when due any and
all Shared Expenses (as defined in the Shared Expenses Agreement) and any Refinancing Expenses not
set forth on the Closing Date Certificate, and in connection with the Closing, reimburse any party
with respect to any Shared Expenses paid by such party.

     12.11 No Third-Party Beneficiaries. Except as otherwise expressly set forth in this
Agreement, nothing in this Agreement will be construed as giving any Person, other than parties
hereto and their respective heirs, successors and permitted assigns, any right, remedy or claim
under or in respect of this Agreement or any provision hereof. HSI and its Subsidiaries and Butler
Holding, BAHS and its Subsidiaries and Affiliates acknowledge and agree that all provisions
contained herein with respect to employees are included for the sole benefit of HSI,

74

 

Butler Holding, BAHS and their respective Affiliates and shall not create any right in any
other Person, including any employees, former employees, participants or former participants in any
Benefit Plans or any beneficiary thereof, or any other third parties. In addition, except as
expressly provided herein, nothing contained herein, expressed or implied, is intended to confer
upon any Vet Business Employee or Transferred Employee any right to employment or continued
employment with HSI, NLS, Butler Holding, BAHS or any of their respective Subsidiaries and
Affiliates or any rights under any Benefit Plan, including severance benefits, by reason of this
Agreement.

     12.12 Further Assurances. Following the Closing, the parties shall execute and deliver to
each other such documents and take such other actions as may reasonably be requested in order to
consummate more effectively the transactions contemplated hereby.

     12.13 “Knowledge” Defined.

          (a) As used herein, “to the knowledge of HSI,” “to HSI’s knowledge,” or any other similar
phrase shall mean the actual knowledge of Edward “Reed” Presnell, Steven Paladino, Ken Williams and
Ronald South, after reasonable inquiry.

          (b) As used
herein, “to the knowledge of Butler Holding,” “to Butler Holding’s knowledge,” “to the knowledge of WA
Butler,” “to WA Butler’s knowledge,” or any other similar phrase shall mean the actual knowledge of Leo “Mac” McNeil, Kevin Vasquez,
Charles B. Patton and Michael Caputo, after reasonable inquiry.

     12.14 Communication Plan; Publicity.

          (a) As soon as reasonably practicable after the date of this Agreement, the parties will work
in good faith and cooperate in the joint development of a communication plan to customers, vendors,
landlords and employees concerning the proposed transactions contemplated by this Agreement (the
“Communication Plan”). The Communication Plan shall be reasonably acceptable to HSI and Butler
Holding.

          (b) It is the current intent of the parties to commence with the communications contemplated
by the Communications Plan promptly following the execution of this Agreement, provided,
however, that HSI and Butler Holding each reserve the right to suspend all communications
contemplated by such plan if it determines in good faith that (i) there is a reasonable possibility
that the transactions contemplated hereby may not close, or (ii) such disclosure could have a
materially adverse impact on such party’s business or the ability of HSI or Butler Holding to close
the transactions contemplated hereby. If it is reasonably necessary to correct any false or
misleading information which may become public concerning the transactions contemplated hereby or
to prevent a material adverse impact on HSI or Butler Holding, the parties will consider in good
faith whether or not to accelerate the communications contemplated by the Communication Plan.

          (c) Pending the Closing, except as expressly permitted by Section 12.14(b) above, no party
shall issue a press release or make any other public announcement (including any internal
communication to employees) concerning the transactions contemplated by this Agreement without the
prior written consent of HSI or Butler Holding, as applicable, except to the extent required by
law, in which case the other party shall have a reasonable opportunity to

75

 

review and comment prior to disclosure. For clarity, it is understood that this Section
12.14(c) shall not prohibit internal communications to the employees of the parties involved in
planning the integration of HSI and Butler Holding post-Closing concerning the proposed
transactions.

     12.15 Acknowledgment. Each party hereto acknowledges that, anything in this Agreement or in
any Transaction Document to the contrary notwithstanding, the representations, warranties,
covenants and agreements of such party contained in this Agreement or in any Transaction Document
shall not be deemed waived by any investigation by another party or any of its officers, directors,
employees, counsel, accountants, advisors, representatives and agents. The right to
indemnification, reimbursement or other remedy based upon any of such representations, warranties,
covenants and agreements shall not be affected by any investigation conducted with respect to, or
any knowledge acquired (or capable of being acquired) at any time, whether before or after the
execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or
inaccuracy of or compliance with any such representation, warranty, covenant or agreement. The
waiver of any condition based upon the accuracy of any representation or warranty, or on the
performance of or compliance with any agreement or covenant, will not affect the right to
indemnification, reimbursement or other remedy based upon such representation, warranty, agreement
or covenant.

     12.16 No Strict Construction. The parties hereto have participated jointly in the negotiation
and drafting of this Agreement and the other Transaction Documents. In the event an ambiguity or
question of intent or interpretation arises under any provision of this Agreement or any other
Transaction Document, this Agreement and such other Transaction Document shall be construed as if
drafted jointly by the parties thereto, and no presumption or burden of proof shall arise favoring
or disfavoring any party by virtue of authoring any of the provisions of this Agreement or any
other Transaction Document.

          NOW, THEREFORE, in consideration of the promises and of the covenants and agreements
hereinafter set forth and for other good and valuable consideration, the receipt and adequacy of
which are hereby acknowledged, the parties hereby agree as follows:

               “Annual Put Limitation Amount” means an amount equal to (i) $125,000,000 for the first
Put Year, (ii) $137,500,000 for the second Put Year and (iii) $150,000,000 for the third Put Year
and for each Put Year thereafter.

               “BAHHC Common Shares” means the “Common Shares” or, following an Initial Public
Offering, the “Successor Common Stock” (each as defined in the Operating Agreement), in each case,
as adjusted for any reclassification, recapitalization, distribution, split, combination, exchange
or similar adjustment thereof.

               “Burns” shall mean Burns Veterinary Supply Inc., a New York corporation.

               “Closing Date” shall have the meaning set forth in the Omnibus Agreement.

 

 

               “Commission” means the United States Securities and Exchange Commission, or any other
federal agency administering the Securities Act and the Exchange Act at the time.

               “Company” shall have the meaning set forth in the Preamble.

               “Convertible Security” means any capital stock, equity or debt security convertible
into, exchangeable for or representing any rights to subscribe for or acquire any BAHHC Common
Shares. For purposes of clarification, “Convertible Security” shall not include any options.

               “Darby” means the Darby Group Companies, Inc., a New York corporation.

               “Decision Period” shall have the meaning set forth in Section 2.2(a)(ii)(2).

               “Designated Investment Banker” shall have the meaning set forth in Section
2.2(a)(ii)(1).

               “Discount Rate” means the  National Municipal Bond yields for AAA Rated Tax Exempt General Obligations
Bonds as reported by Bloomberg for the nearest period of time remaining with respect to
the tax liabilities applicable to the FIFO tax adjustment, which, as of November 29, 2009 is 0.66%
for the two (2) year bond.

               “Enterprise Value Methodology” means a methodology to be considered by the Designated
Investment Banker in connection with its determination of Fair Market Value, whereby first, the
enterprise value of the Company is calculated by multiplying (i) normalized EBITDA by (ii) an
appropriate multiple as determined by the Designated Investment Banker, and second, total cash and
cash equivalents of the Company and its subsidiaries as of the most recent full month-end balance
sheet date immediately preceding the applicable Put Notice Date would be added thereto, and third,
from the enterprise value so calculated, the total indebtedness of the Company and its subsidiaries
for borrowed monies as of the most recent full month-end balance sheet date immediately preceding
the applicable Put Notice Date would be subtracted.

               “Excess Tax Distribution Adjustment Amount” for OHCP or OHCM means an amount equal to the difference
between (i) the aggregate net amount that would have been received by OHCP or OHCM, as applicable, with respect to the
Put Securities if on the day immediately preceding the Put Closing Date the Company had made a
distribution to its members in the minimum amount sufficient to eliminate the distribution advances
to all members (including accrued amounts in the nature of interest) provided for in Section
6.6(a)(ii) of the Operating Agreement outstanding as of that day (the “First Distribution”)
and then redistributed the amount of distribution advances treated as repaid pursuant to Section
6.6(a)(ii) (followed, in the case of OHCP, by a distribution by WABC of the proceeds of those distributions) and (ii) the
aggregate amount that would have been received by Oak Hill with respect to the Put Securities if on
the day immediately preceding the Put Closing Date the Company had made a distribution to its
members in the amount of the First Distribution (and, in the case of OHCP, followed by a distribution of the proceeds of this
distribution) but on that date the amount of the distribution
advances provided for in that Section 6.6(a)(ii) for all members had been zero (in both cases not
taking account of any adjustments relating to tax liabilities resulting from the change by the
Company from the LIFO to the FIFO inventory
accounting method). To the extent the amount determined under clause (i) of the immediately
preceding sentence exceeds the amount determined under clause (ii) of that sentence the Excess Tax
Distribution Adjustment Amount shall be considered “positive”; to the extent the amount

2

 

determined
under that clause (ii) exceeds the amount determined under that clause (i) the Excess Tax
Distribution Adjustment Amount shall be considered “negative.”
Attached hereto as Exhibit A is an example of the Excess Tax Distribution Adjustment Amount calculation set forth above.

               “Fair Market Value” means the fair market value of 100% of the equity interests of the
Company, calculated as of the relevant Put Notice Date (except as specifically provided in the
definition of Enterprise Value Methodology), determined pursuant to Section 2.2(a) or

options at any time on or after the applicable Put Notice Date through the date immediately preceding the applicable Put Closing Date.

               “HSI Change of Control” means (a) if any “person” or “group” (as such terms are used

(discounted at the Discount Rate) of the amount of tax liability to be borne by OHCP or OHCM, as applicable, with
regard to that income pursuant to the last sentence of Section 4.1 of the Operating Agreement,
based on the Corporate Tax Rate (as defined in the Operating Agreement, based on the operations of

               “WABC Ownership Percentage” means a percentage equal to the number of BAHHC Common
Shares owned by WABC divided by the total number of BAHHC Common Shares then issued and
outstanding, determined on a fully diluted basis, taking into account
option dilution for In the Money Options, in each case as calculated as of the Put
Notice Date (except as indicated in the definition of In the Money
Options).

ARTICLE II

PUT RIGHTS

     2.1. Put Right Grants and Mechanics.

              (a) HSI hereby grants to Oak Hill the right (a “Put Right”), at any time and from time
to time on or after the earlier of (x) first anniversary of the Closing Date or (y) an HSI Change
of Control, to require HSI to purchase all or any portion of the Securities then owned by Oak Hill,
on the terms and subject to the conditions set forth in this Agreement.

              (b) Oak Hill may exercise its Put Right by delivery of a written Notice (a “Put
Notice”) to HSI, which Put Notice shall state that Oak Hill is exercising its Put Right to
require HSI to purchase the number and type of Securities specified in such Put Notice (the
“Put Securities”).

          2.2. Determination of Fair Market Value. For purposes of calculating Put Price
payable in connection with the exercise of any Put Right, the Fair Market Value shall be determined
as follows:

              (a) Pre-QPO. If the Put Notice is delivered prior to a Qualified Initial Public
Offering, the Put Price payable in connection with the exercise of any Put Right shall be
determined as follows:

     (i) Mutual Agreement. Oak Hill and HSI shall use all reasonable
efforts and negotiate in good faith to agree upon the Fair Market Value. If Oak
Hill and HSI agree upon the Fair Market Value, then, subject to the conditions to
closing set forth in Section 2.4 below, Oak Hill shall sell, transfer and
convey, and HSI shall purchase and accept, the Put Securities free and clear of all
Liens at the Put Closing for the Put Price calculated based on such agreed-upon Fair
Market Value.

6

 

     (ii) Dispute Procedures. (1) If Oak Hill and HSI are unable to agree
upon the Fair Market Value pursuant to Section 2.2(a)(i) within twenty-one
(21) days of the Put Notice Date, then either party may request, by delivery of a
written Notice to the other party, a reputable independent nationally
recognized investment bank retained by the Company, or, if such investment bank is not acceptable to Oak Hill or HSI, another
reputable independent nationally recognized investment bank as to which HSI and Oak
Hill mutually agree (the “Designated Investment Banker”), that the
Designated Investment Banker determine the Fair Market Value. If HSI and Oak Hill
are unable to agree upon the selection of the Designated Investment Banker, then
each shall select one nationally recognized investment bank and the Designated
Investment Banker shall be selected by those two investment banks, whose
determination of the Designated Investment Banker will constitute an arbitral award
that is final, binding and non-appealable and upon which a judgment may be entered
by a court with jurisdiction thereover. The Designated Investment Banker shall
determine the Fair Market Value, using such method or methods of determining Fair
Market Value as it, in its sole discretion, shall determine; provided,
however, that in determining Fair Market Value, the Designated Investment
Banker shall (A) not include a discount for lack of control, minority interests,
lack of a public market in the Company’s securities or leverage levels, block sale
discounts or otherwise take into account any contractual restrictions on the
Company’s ability to operate anywhere in the world or limiting HSI’s ability to
consummate the Put Closing (other than as set forth in this Agreement), (B)
consider, among other things, the value that could be realized by a sophisticated
seller seeking to maximize the consideration to be received for the Put Securities,
whether through a private sale of 100% of the Company or a strategic combination or
in an Initial Public Offering (determined on a fully distributed basis) and
assuming, for purposes of the valuation, that the capital stock of the Company is
widely held and no one shareholder holds a control position), without taking into
consideration any initial public offering discount or underwriter’s discount or any
other costs or expenses of sale, and (C) consider, in addition to any other methods
deemed by the Designated Investment Banker, in its sole discretion, to be customary
or appropriate, the Enterprise Value Methodology. For the avoidance of doubt, the
Designated Investment Banker shall not consider or attribute any value (or negative
value) to any distribution advances by the Company provided for in Section
6.6(a)(ii) of the Operating Agreement or tax liabilities relating to the change from
the LIFO to the FIFO inventory accounting method, which is the subject of the last
sentence of Section 4.1 of the Operating Agreement. Upon reasonable notice, the
Designated Investment Banker shall provide each of Oak Hill and HSI the opportunity
to make one presentation (with representatives of the non-presenting party present)
of reasonable length to the Designated Investment Banker regarding their respective
views on the determination of Fair Market Value; provided that any materials
provided by any party to the Designated Investment Banker in connection with such
presentation shall be simultaneously provided to the other party. The Designated
Investment Banker shall issue its determination in writing to Oak Hill and HSI (the
“Final Determination”) within forty-five (45) days of

7

 

delivery of the initial Notice to the Designated Investment Banker requesting
such determination and will constitute an arbitral award that is final, binding and
non-appealable and upon which judgment may be entered by a court with jurisdiction
thereover.

     (2) Oak Hill shall have fifteen (15) days after delivery of the Final
Determination (the “Decision Period”) to decide whether to (A) withdraw its
Put Notice or (B) require HSI to purchase the Put Securities indicated in its Put
Notice for a price equal to the Put Price calculated based on the Fair Market Value
set forth in the Final Determination, which decision shall be furnished to HSI by
written Notice delivered prior to the expiration of the Decision Period, notifying
HSI of such decision (the “Final Notice”). If the Final Notice indicates
that Oak Hill is withdrawing its Put Notice or if Oak Hill fails to deliver a Final
Notice prior to the expiration of the Decision Period, then the Put Notice shall be
deemed to be irrevocably withdrawn and HSI shall not be required to purchase the Put
Securities specified in such Put Notice. Any Put Notice that is withdrawn pursuant
to this Section 2.2(a)(ii)(2) shall continue to be deemed to have been
delivered for purposes of Section 2.5(c).

          (b) Post-QPO. If the Put Notice is delivered after a Qualified Initial Public
Offering: (i) if the BAHHC Common Shares are then listed or quoted on NASDAQ or NYSE, the Put Price
shall be equal to the Market Price, and (ii) if the BAHHC Common Shares are not then listed or
quoted on NASDAQ or NYSE, the Fair Market Value shall be determined in accordance with Section
2.2(a). In lieu of exercising a Put Right hereunder, Oak Hill may, subject to any restriction
set forth in the Registration Rights Agreement and any applicable securities law restrictions, sell
any or all of their respective BAHHC Common Shares on the open market pursuant to Rule 144 of the
Securities Act or the Registration Rights Agreement.

     2.3. Payment of Put Price. The Put Price payable by HSI at the Put Closing shall be
payable in a single cash payment by wire transfer of immediately available funds to an account
designated by Oak Hill in writing at least two (2) days prior to the Put Closing.

     2.4. Put Closing; Conditions Precedent.

          (a) HSI and Oak Hill shall consummate the sale of the Put Shares (the “Put Closing”)
as soon as reasonably practicable after the delivery of the Final Notice to HSI, but in no event
later than thirty (30) days after delivery of the Final Notice (the “Put Closing Date”),
subject in all respects to the satisfaction of the conditions set forth in Sections 2.4(b)
and 2.4(c).

          (b) HSI’s obligations to purchase the Put Securities at a Put Closing shall be expressly
subject to the fulfillment or express written waiver by HSI of the following conditions on or prior
to the applicable Put Closing Date:

     (i) HSI shall have received from Oak Hill certificates or other instruments
representing the Put Securities, together with unit, stock or other appropriate
powers duly endorsed with respect thereto,  together with and any other documentation
reasonably requested by HSI in order to confirm that such

8

 

Put Shares, and all rights in respect thereof (including, without limitation,
all economic and voting rights) are being transferred to HSI free and clear of all
Liens.

     (ii) There shall not be any order of any Governmental Authority restraining or
invalidating the transactions which are the subject of this Agreement.

     (iii) The purchase and sale of the Put Securities at the Put Closing would not
violate the Securities Act or any state securities or “blue sky” laws applicable to
Oak Hill, HSI, the Company or the Put Securities.

          (c) Oak Hill’s obligations to sell the Put Securities at a Put Closing shall be expressly
subject to the fulfillment or express written waiver by Oak Hill of the following conditions on or
prior to the applicable Put Closing Date:

     (i) HSI shall have paid the Put Price.

     (ii) There shall not be any order of any Governmental Authority restraining or
invalidating the transactions which are the subject of this Agreement.

     (iii) The purchase and sale of the Put Securities at the Put Closing would not
violate the Securities Act or any state securities or “blue sky” laws applicable to
Oak Hill, HSI, the Company or the Put Securities.

          (d) If any of the conditions set forth in Section 2.4(b) and 2.4(c) are not or are not
reasonably expected to be satisfied on the Put Closing Date, HSI and Oak Hill shall cooperate in
good faith to cause such conditions to be satisfied.

     2.5. Additional Terms and Conditions Applicable to Put Rights.

          (a) Oak Hill shall only be permitted to exercise its Put Right if the Put Price for the Put
Securities to be acquired from Oak Hill at the applicable Put Closing is equal to or greater than
fifty million dollars ($50,000,000), unless the Put Securities constitute all of the Put Securities
then owned by Oak Hill. If, upon determination of the Put Price payable to Oak Hill in connection
with its exercise of a Put Right in accordance with the terms hereof, the Put Price is less than
fifty million dollars ($50,000,000), unless the Put Securities constitute all of the Put Securities
then owned by Oak Hill, then the Put Notice corresponding to such Put Right shall be void ab initio
and HSI shall have no obligation with respect thereto.

          (b) In
any Put Year, HSI shall not be required to pay, in the aggregate, Put
Prices hereunder in excess
of the applicable Annual Put Limitation Amount. If the Put Price otherwise payable by HSI hereunder on a Put
Closing Date, when combined with all other Put Prices paid by HSI hereunder during the Put Year in which such
Put Closing Date is to occur, would exceed the Annual Put Limitation Amount, then, subject to
Section 2.5(a), HSI shall only be obligated to purchase that portion of the Put Securities
that have an aggregate Put Price so that, when combined with all other Put Prices paid by HSI
hereunder during the Put Year in which such Put Closing Date is to occur, the

9

 

Annual Put Limitation Amount is not exceeded, and the number of Put Securities to be acquired
on such Put Closing Date shall be reduced accordingly on a pro rata basis.

          (c) No Put Notice may be delivered if a Put Notice has already been delivered during the
immediately preceding twelve (12) month period, and any such Put Notice shall be void ab initio;
provided, however, if a Put Notice is withdrawn pursuant to Sections
2.2(a)(ii)(2) or 2.5(a), then Oak Hill may deliver a Put Notice after the date that is
six (6) months following the (x) expiration of the applicable Decision Period in the case of
Section 2.2(a)(ii)(2) and (y) date of determination that the Put Price is less than
$50,000,000 under Section 2.5.

          (d) The Company shall, and HSI and Oak Hill shall cause the Company to, provide the Designated
Investment Banker with access, upon reasonable notice and during normal business hours, to
management of the Company and to such documents and information as it shall reasonably request,
including, without limitation, the most recently approved Company Budget and projections for the
Company’s next fiscal year presented by Company management to the Company Board. Any access under
this Section 2.5(d) shall be subject to such limitations as the Company may reasonably
require to prevent the disclosure of non-public information and/or the material disruption of the
business of the Company, including, without limitation, the execution of a non-disclosure agreement
by the Designated Investment Banker in form and substance reasonably satisfactory to the Company.
The Company shall provide reasonable prior written notice to HSI and Oak Hill of any access to be
provided by the Company to the Designated Investment Banker. HSI, Oak Hill and their respective
representatives shall have the right to accompany the Designated Investment Banker on any visits to
Company’s facilities or in any meetings between the Designated Investment Banker and management of
the Company.

          (e) All fees, costs and expenses of the Designated Investment Banker incurred in connection
with the determination of the Put Price hereunder shall be borne by the Company.

          (f) The Put Rights granted hereunder are personal to Oak Hill and may not be transferred or
assigned by Oak Hill other than in accordance with Section 3.8 hereof.

               “Enterprise Value Methodology” means a methodology to be considered by the Designated

2

 

recent full month-end balance sheet date immediately preceding the applicable Put Notice Date would

6.6(a)(ii) of the Operating Agreement outstanding as of that day (the “First Distribution”)
and then redistributed the amount of distribution advances treated as repaid pursuant to Section
6.6(a)(ii), and (ii) the aggregate amount that would have been received by Burns with respect to

ARTICLE II

PUT RIGHTS

     2.1. Burns Put Right Grants and Mechanics.

          (a) HSI hereby grants to Burns the right (a “Burns Put Right”), at any time and from
time to time on or after the fifth anniversary of the Closing Date, to require HSI to purchase all
or any portion of the BAHHC Common Shares then owned by Burns, on the terms and
subject to the conditions set forth in this Agreement.

          (b) Subject to Sections 2.5(a) through (c), Burns may exercise its Burns Put Right by delivery
of a written Notice (a “Put Notice”) to HSI, which Put Notice shall state that Burns is
exercising its Burns Put Right to require HSI to purchase the number and type of BAHHC Common
Shares specified in such Put Notice (the “Put Securities”)
and may, if such Put Notice is being delivered at any time prior to
the first anniversary of the Oak Hill Divestiture Date, state the
minimum number of Put Securities that would be acceptable to Burns
if all such Put Securities are greater than the Annual Burns Put
Limitation Amount.

     2.2. Determination of Fair Market Value. For purposes of calculating Burns Put Price
payable in connection with the exercise of any Burns Put Right, the Fair Market Value shall be
determined as follows:

       (a) Pre-QPO. If the Put Notice is delivered prior to a Qualified Initial Public
Offering, the Burns Put Price payable in connection with the exercise of any Burns Put Right shall
be determined as follows:

     (i) Mutual Agreement. Burns and HSI shall use all reasonable efforts
and negotiate in good faith to agree upon the Fair Market Value. If Burns and HSI
agree upon the Fair Market Value, then, subject to the conditions to closing set
forth in Section 2.4 below, Burns shall sell, transfer and convey, and HSI
shall purchase and accept, the Put Securities free and clear of all Liens at the
Burns Put Closing for the Burns Put Price calculated based on such agreed-upon Fair
Market Value.

     (ii) Dispute Procedures. (1) If Burns and HSI are unable to agree upon
the Fair Market Value pursuant to Section 2.2(a)(i) within twenty-one (21)
days of the Put Notice Date, then either party may request, by delivery of a written
Notice to the other party, an independent investment bank retained by the Company,
or, if such investment bank is not acceptable to Burns or HSI, another reputable
independent nationally recognized investment bank as to which HSI and Burns mutually
agree (the “Designated Investment Banker”), that the Designated Investment
Banker determine the Fair Market Value. If HSI and Burns are unable to agree upon
the selection of the Designated Investment Banker, then each shall select one
nationally recognized investment bank and the Designated Investment Banker shall be
selected by those two investment banks, whose determination of the Designated
Investment Banker will constitute an arbitral award that is final, binding and
non-appealable and upon which a judgment may be entered by a
court with jurisdiction thereover. The Designated Investment Banker shall
determine the Fair Market Value, using such method or methods of determining Fair
Market Value as it, in its sole discretion, shall determine; provided,
however, that in determining Fair Market Value, the Designated Investment
Banker shall (A) not include a discount for lack of control, minority interests,
lack of a public market in the Company’s securities or leverage levels, block sale
discounts or

6

 

otherwise take into account any contractual restrictions on the Company’s
ability to operate anywhere in the world or limiting HSI’s ability to consummate the
Burns Put Closing (other than as set forth in this Agreement), (B) consider, among
other things, the value that could be realized by a sophisticated seller seeking to
maximize the consideration to be received for the Put Securities, whether through a
private sale of 100% of the Company or a strategic combination or in an Initial
Public Offering (determined on a fully distributed basis) and assuming, for purposes
of the valuation, that the capital stock of the Company is widely held and no one
shareholder holds a control position), without taking into consideration any initial
public offering discount or underwriter’s discount or any other costs or expenses of
sale, and (C) consider, in addition to any other methods deemed by the Designated
Investment Banker, in its sole discretion, to be customary or appropriate, the
Enterprise Value Methodology. For the avoidance of doubt, the Designated
Investment Banker shall not consider or attribute any value (or negative value) to
any distribution advances by the Company provided for in Section 6.6(a)(ii) of the
Operating Agreement or tax liabilities relating to the change from the LIFO to the
FIFO inventory accounting method, which is the subject of the last sentence of
Section 4.1 of the Operating Agreement. Upon reasonable notice, the Designated
Investment Banker shall provide each of Burns and HSI the opportunity to make one
presentation (with representatives of the non-presenting party present) of
reasonable length to the Designated Investment Banker regarding their respective
views on the determination of Fair Market Value; provided that any materials
provided by any party to the Designated Investment Banker in connection with such
presentation shall be simultaneously provided to the other party. The Designated
Investment Banker shall issue its determination in writing to Burns and HSI (the
“Final Determination”) within forty-five (45) days of delivery of the
initial Notice to the Designated Investment Banker requesting such determination and
will constitute an arbitral award that is final, binding and non-appealable and upon
which judgment may be entered by a court with jurisdiction thereover.

     (2) Burns shall have fifteen (15) days after delivery of the Final
Determination (the “Decision Period”) to decide whether to (A) withdraw its
Put Notice or (B) require HSI to purchase the Put Securities indicated in its Put
Notice for a price equal to the Burns Put Price calculated based on the Fair Market
Value set forth in the Final Determination, which decision shall be furnished to HSI
by written Notice delivered prior to the expiration of the Decision Period,
notifying HSI of such decision (the “Final Notice”). If the Final Notice
indicates that Burns is withdrawing its Put Notice or if Burns fails to deliver a
Final Notice prior to the expiration of the Decision Period, then the Put Notice
shall be deemed to be irrevocably withdrawn and HSI shall not be required to
purchase the Put Securities specified in such Put Notice. Any Put Notice that is
withdrawn pursuant to this Section 2.2(a)(ii)(2) shall continue to be deemed
to have been delivered for purposes of Section 2.5(c).

          (b) Post-QPO. If the Put Notice is delivered after a Qualified Initial Public
Offering: (i) if the BAHHC Common Shares are then listed or quoted on NASDAQ or NYSE,

7

 

the Burns Put Price shall be equal to the Market Price, and (ii) if the BAHHC Common Shares
are not then listed or quoted on NASDAQ or NYSE, the Fair Market Value shall be determined in
accordance with Section 2.2(a). In lieu of exercising a Burns Put Right hereunder, Burns
may, subject to any restriction set forth in the Registration Rights Agreement and any applicable
securities law restrictions, sell any or all of their respective BAHHC Common Shares on the open
market pursuant to Rule 144 of the Securities Act or the Registration Rights Agreement.

     2.3. Payment of Burns Put Price. The Burns Put Price payable by HSI at the Burns Put
Closing shall be payable in a single cash payment by wire transfer of immediately available funds
to an account designated by Burns in writing at least two (2) days prior to the Burns Put Closing.

     2.4. Burns Put Closing; Conditions Precedent. 

          (a) HSI and Burns shall consummate the sale of the Put Shares (the “Burns Put
Closing”) as soon as reasonably practicable after the delivery of the Final Notice to HSI, but
in no event later than thirty (30) days after delivery of the Final Notice (the “Burns Put
Closing Date”), subject in all respects to the satisfaction of the conditions set forth in
Sections 2.4(b) and 2.4(c).

          (b) HSI’s obligations to purchase the Put Securities at a Burns Put Closing shall be expressly
subject to the fulfillment or express written waiver by HSI of the following conditions on or prior
to the applicable Burns Put Closing Date:

     (i) HSI shall have received from Burns certificates or other instruments
representing the Put Securities, together with unit, stock or other appropriate
powers duly endorsed with respect thereto, if applicable, together with and any other documentation
reasonably requested by HSI in order to confirm that such Put Shares, and all rights
in respect thereof (including, without limitation, all economic and voting rights)
are being transferred to HSI free and clear of all Liens.

     (ii) There shall not be any order of any Governmental Authority restraining or
invalidating the transactions which are the subject of this Agreement.

     (iii) The purchase and sale of the Put Securities at the Burns Put Closing
would not violate the Securities Act or any state securities or “blue sky” laws
applicable to Burns, HSI, the Company or the Put Securities.

          (c) Burns’s obligations to sell the Put Securities at a Burns Put Closing shall be expressly
subject to the fulfillment or express written waiver by Burns of the following conditions on or
prior to the applicable Burns Put Closing Date:

     (i) HSI shall have paid the Burns Put Price.

8

 

     (ii) There shall not be any order of any Governmental Authority restraining or
invalidating the transactions which are the subject of this Agreement.

     (iii) The purchase and sale of the Put Securities at the Burns Put Closing
would not violate the Securities Act or any state securities or “blue sky” laws
applicable to Burns, HSI, the Company or the Put Securities.

          (d) If any of the conditions set forth in Section 2.4(b) and 2.4(c) are not or are not
reasonably expected to be satisfied on the Burns Put Closing Date, HSI and Burns shall cooperate in
good faith to cause such conditions to be satisfied.

     2.5. Additional Terms and Conditions Applicable to Burns Put Rights.

          (a) During any Pre Divestiture Put Year, Burns shall only be permitted to exercise its Burns
Put Right  during the 30-Day True-Up Period.

          (b) In any Put Year, HSI shall not be required to pay, in the aggregate, Burns Put Prices or
acquire, in the aggregate, that number of Put Securities, as applicable, in excess of the
applicable Annual Burns Put Limitation Amount. If the Burns Put Price otherwise payable by HSI, or
the number of Put Securities otherwise to be acquired by HSI, on a Burns Put Closing Date, when
combined with all other Burns Put Prices and Oak Hill Put Prices paid by HSI during the Put Year in
which such Burns Put Closing Date is to occur, would exceed the Annual Burns
Put Limitation Amount, then HSI shall only be obligated to purchase that portion of the Put
Securities so that, when combined with all other Burns Put Prices paid by HSI and Put Securities
acquired by HSI during the Put Year in which such Burns Put Closing Date is to occur (or deemed to
occur), the Annual Burns Put Limitation Amount is not exceeded, and the number of Put Securities to
be acquired on such Burns Put Closing Date shall be reduced accordingly. If Burns exercises its
Burns Put Right during a 30-Day True-Up Period pursuant to sub-section (b) of the definition of 30-Day True-Up Period, then the prior year’s Annual Burns Put Limitation Amount
shall be applicable; provided, however, that, if Oak Hill delivers an Oak Hill Put Notice following the
delivery of a Put Notice by Burns but prior to the applicable Put Closing therefor, then (x) the Put Closing in
respect of such Put Notice from Burns  shall be delayed so that such Put Closing shall occur
immediately following the applicable Oak Hill Put Closing, (y) the
Fair Market Value or Market Price, as applicable, shall equal the value or price used in connection with the applicable Oak Hill Put
Closing and (z) if, after giving effect to such Oak Hill Put Closing, the number of Put Securities that would be within the applicable Annual
Burns Put Limitation Amount is less than the minimum number specified
in the Put Notice, then Burns may withdraw such Put Notice and the
next Put Notice delivered by Burns during the remainder of such Put
Year shall not be subject to the provisions of Section 2.5(c).

          (c) No Put Notice may be delivered if a Put Notice has already been delivered during the
immediately preceding twelve (12) month period, and any such Put Notice shall be void ab initio;
provided, however, if a Put Notice is withdrawn pursuant to Sections
2.2(a)(ii)(2) then Burns may deliver a Put Notice after the date that is six (6) months
following the expiration of the applicable Decision Period in the case of Section
2.2(a)(ii)(2).

          (d) The Company shall, and HSI and Burns shall cause the Company to, provide the Designated
Investment Banker with access, upon reasonable notice and during normal business hours, to
management of the Company and to such documents and information as it shall reasonably request,
including, without limitation, the most recently approved Company Budget and projections for the
Company’s next fiscal year presented by Company management to the Company Board. Any access under
this Section 2.5(d) shall be subject to such limitations

9

 

as the Company may reasonably require to prevent the disclosure of non-public information
and/or the material disruption of the business of the Company, including, without limitation, the
execution of a non-disclosure agreement by the Designated Investment Banker in form and substance
reasonably satisfactory to the Company. The Company shall provide reasonable prior written notice
to HSI and Burns of any access to be provided by the Company to the Designated Investment Banker.
HSI, Burns and their respective representatives shall have the right to accompany the Designated
Investment Banker on any visits to Company’s facilities or in any meetings between the Designated
Investment Banker and management of the Company.

          (e) All fees, costs and expenses of the Designated Investment Banker incurred in connection
with the determination of the Burns Put Price hereunder shall be borne by the Company.

          (f) The Burns Put Rights granted hereunder are personal to Burns and may not be transferred or
assigned by Burns other than in accordance with Section 3.8 hereof.
