Date and shall not take into account or otherwise give effect to the transactions contemplated by
this Agreement to occur after the Closing Date.

          (ii) A statement setting forth the Buyer’s calculation of Adjusted Net Working Capital and the
Merger Consideration. The Parties agree that the purpose of preparing the Closing Date Balance
Sheet is to determine the amount of the Adjusted Net Working Capital and to reconcile any
differences between such amount and the Target Net Working Capital. Such process is not intended
to permit the introduction of different components, judgments, accounting methods, policies,
principles, practices, procedures, classifications or estimation methodologies for the purpose of
preparing the Closing Date Balance Sheet or determining the Adjusted Net Working Capital from the
judgments, accounting methods, policies, principles, practices, procedures, classifications or
estimation methodologies described in the Working Capital Methodology or used in determining the
Target Working Capital, except to the extent that any existing accounting methods, policies,
principles, practices, procedures, classifications or estimation methodologies are not in
accordance with GAAP (other than such differences set forth on Exhibit B).

     (b) Access to Records. The Stockholder Representative shall be given timely access to
all supporting documents and work papers used in the preparation of the Closing Date Balance Sheet,
as reasonably requested in connection with its review of the Closing Date Balance Sheet and the
calculation of the Adjusted Net Working Capital.

     (c) Resolution of Disputes. The Stockholder Representative may dispute any amounts
reflected on the Closing Date Balance Sheet or the calculation of the Adjusted Net Working Capital;
provided, however, that the Stockholder Representative shall have notified Buyer in
writing of each disputed item, specifying the amount thereof in dispute and setting forth, in
reasonable detail, the basis for such dispute, as promptly as practicable but in any event no later
than the 30th day following receipt by the Stockholder Representative of the items described in
Section 2.5(a). In the event of such a dispute, Buyer and the Stockholder Representative
shall attempt to reconcile their differences. If Buyer and the Stockholder Representative are
unable to reach a resolution with such effect within thirty (30) days after receipt by Buyer of the
Stockholder Representative’s written notice of dispute, Buyer and the Stockholder Representative
shall submit the items remaining in dispute for resolution to the accounting firm of KPMG LLP (the
“Independent Accounting Firm”), which shall, within thirty (30) days after such submission,
determine and report to Buyer and the Stockholder Representative upon such remaining disputed
items, and such report shall be final and binding on the Parties absent fraud or intentional
misconduct. The fees and disbursements of the Independent Accounting Firm (the “Aggregate
Accounting Fees”) shall be allocated between Buyer, on the one hand, and the Sellers, on the
other hand, as follows: a portion of the Aggregate Accounting Fees equal to the product of the
Aggregate Accounting Fees and a fraction, the numerator of which is the aggregate dollar amount of
the disputed items resolved by the Independent Accounting Firm in favor of Buyer and the
denominator of which is the aggregate dollar amount of all disputed items submitted to the
Independent Accounting Firm for resolution, shall be allocated to the Sellers, and the remainder
shall be allocated to Buyer (in each case as finally determined by the Independent Accounting
Firm). In acting under this Agreement, the Independent Accounting Firm shall be entitled to the
privileges and immunities of arbitrators.

     (d) Adjustments Final. The Merger Consideration, the Closing Date Balance Sheet and
the Adjusted Net Working Capital shall be deemed final for the purposes of this Agreement upon the
earlier of (i) the failure of the Stockholder Representative to notify Buyer of a dispute by the
30th day following receipt by the Stockholder Representative of the items described in Section
2.5(a), (ii) the resolution of all disputes pursuant to Section 2.5(c) by the
Stockholder Representative and Buyer and (iii) the resolution of all disputes pursuant to
Section 2.5(c) by the Independent Accounting Firm. The final determinations of such
matters shall be non-appealable and incontestable by the Parties and each of their respective
Affiliates and successors and assigns and not subject to collateral attack for any reason other
than manifest error or fraud.

     (e) Reconciliation Payments.

          (i) If the Adjusted Net Working Capital, as determined pursuant to this Section 2.5,
exceeds the Target Net Working Capital, then Buyer shall pay to the Sellers, in the aggregate, an
amount equal to such excess by wire transfer in immediately available funds to the account or
accounts designated by the Stockholder Representative no later than five (5) business

days following the final determination of the Adjusted Net Working Capital in accordance with
Section 2.5(d).

          (ii) If the Target Net Working Capital exceeds the Adjusted Net Working Capital, as determined
pursuant to this Section 2.5, then such excess shall be paid by the Escrow Agent to the
Buyer from the Indemnity Escrow Amount by wire transfer of immediately available funds to the
account designated by Buyer no later than five (5) business days following the final determination
of the Adjusted Net Working Capital in accordance with Section 2.5(d).

       2.6 Post-Closing Reconciliation of Product Returns.

     (a) Buyer Return Statements. At any time and from time to time following the
Effective Time, the Buyer may deliver to the Stockholder Representative a statement setting forth
the aggregate Product Return Amount as of the date specified in such statement (each, a “Return
Statement”); provided, however, that the Buyer may not deliver a Return
Statement (i) until the aggregate Product Return Amount exceeds $[...***...], (ii) more frequently than
once per calendar quarter or (iii) with respect to any returns received after the three (3) year
anniversary of the Effective Time. The final Return Statement shall be delivered within sixty (60)
days after the three (3) year anniversary of the Effective Time.

     (b) Access to Records. The Stockholder Representative shall be given timely access to
all supporting documents and work papers used in the preparation of the Return Statement, as
reasonably requested in connection with its review of the Return Statement and the calculation of
the aggregate Product Return Amount.

     (c) Resolution of Disputes. The Stockholder Representative may dispute any amounts
reflected on a Return Statement or the calculation of the Product Return Amount set forth thereon;
provided, however, that the Stockholder Representative shall have notified Buyer in
writing of each disputed item, specifying the amount thereof in dispute and setting forth, in
reasonable detail, the basis for such dispute, as promptly as practicable but in any event no later
than the 30th day following receipt by the Stockholder Representative of the Return Statement. In
the event of such a dispute, Buyer and the Stockholder Representative shall attempt to reconcile
their differences. If Buyer and the Stockholder Representative are unable to reach a resolution
with such effect within thirty (30) days after receipt by Buyer of the Stockholder Representative’s
written notice of dispute, Buyer and the Stockholder Representative shall submit the items
remaining in dispute for resolution to the Independent Accounting Firm, which shall, within thirty
(30) days after such submission, determine and report to Buyer and the Stockholder Representative
upon such remaining disputed items, and such report shall be final and binding on the Parties
absent fraud or intentional misconduct. The Aggregate Accounting Fees relating to such dispute
shall be allocated between Buyer, on the one hand, and the Sellers, on the other hand, as follows:
a portion of the Aggregate Accounting Fees equal to the product of the Aggregate Accounting Fees
and a fraction, the numerator of which is the aggregate dollar amount of the disputed items
resolved by the Independent Accounting Firm in favor of Buyer and the denominator of which is the
aggregate dollar amount of all disputed items submitted to the Independent Accounting Firm for
resolution, shall be allocated to the Sellers, and the remainder shall be allocated to Buyer (in
each case as finally determined by the Independent

Accounting Firm). In acting under this Agreement, the Independent Accounting Firm shall be
entitled to the privileges and immunities of arbitrators.

     (d) Adjustments Final. A Return Statement and the aggregate Product Return Amount as
of the date of such Return Statement shall be deemed final for the purposes of this Agreement upon
the earlier of (i) the failure of the Stockholder Representative to notify Buyer of a dispute by
the 30th day following receipt by the Stockholder Representative of such Return
Statement, (ii) the resolution of all disputes pursuant to Section 2.6(c) by the
Stockholder Representative and Buyer and (iii) the resolution of all disputes pursuant to
Section 2.6(c) by the Independent Accounting Firm. The final determinations of such
matters shall be non-appealable and incontestable by the Parties and each of their respective
Affiliates and successors and assigns and not subject to collateral attack for any reason other
than manifest error or fraud.

     (e) Reconciliation Payments. If the aggregate Product Return Amount as of the date of
a Return Statement, as determined pursuant to this Section 2.6, exceeds the sum of $[...***...]
plus the aggregate amount of all previous payments to the Buyer pursuant to this Section
2.6(e), then such excess shall be paid by the Escrow Agent to the Buyer from the Return Escrow
Amount by wire transfer of immediately available funds to the account designated by Buyer no later
than five (5) business days following the final determination of such Product Return Amount in
accordance with Section 2.6(d). Amounts held by the Escrow Agent pursuant to the Return
Escrow Agreement shall be the sole and exclusive remedy of the Buyer and its Affiliates (including
the Surviving Corporation) in respect of any Product Return Amount. For the purposes of clarity,
the Buyer shall not be entitled to any payment, pursuant to this Section 2.6 or otherwise,
with respect to any portion of the aggregate Product Return Amount that is less than $[...***...] or
with respect to any portion of the aggregate Product Return Amount that is in excess of $[...***...].
Any portion of the Return Escrow Amount not required to be disbursed to the Buyer pursuant to this
Section 2.6(e) in respect of Return Statements delivered on or before the three (3) year
anniversary of the Effective Time shall be promptly disbursed by the Escrow Agent to the
Stockholder Representative (on behalf of the Sellers).

respect thereto; (ii) Healthpoint holds good and marketable title to the Facility; (iii) the

Company.

     (g) To the Sellers’ Knowledge, there are no Hazardous Materials in the soil or groundwater at
the Facilities in concentrations above regulatory action levels which require either remediation
under Environmental Laws or the reporting of the same to environmental regulatory agencies having

          3.11 Employee Benefit Plans.

     Schedule 3.11 sets forth a list of all bonus, deferred or incentive compensation,
profit sharing, retirement, vacation, sick leave, disability, unemployment, accident,
hospitalization or severance plans and agreements, “employee benefit plans” (as defined in
Section 3(3) of ERISA), employment and consulting agreements, change in control agreements,
retention and fringe benefit plans sponsored, maintained or contributed to by the Company or any
ERISA Affiliate and in which the employees (or former employees) of the Company participate or are
entitled to participate as of the Effective Date or within the six-year period ending on the
Effective Date, whether or not in writing, funded or unfunded (including, without limitation, any
“voluntary employees’ beneficiary association” as defined in Section 501(c)(9) of the Code) (the
“Benefit Plans”). The Company is neither a plan sponsor nor a “named fiduciary” of any
Benefit Plan. The Company has made available to Buyer copies of all documents (including the most
recent plan document incorporating all plan amendments, the most recent summary plan description
and, if applicable, the most recent IRS determination or opinion letter) embodying the Benefit
Plans, as well as annual reports (IRS Form 5500 series or the alternative filing, if applicable,
under ERISA Regulation Section 2520.104-23) and certified financial statements for the most
recently completed three fiscal years for each Benefit Plan required to file such form, copies of
all documentation relating to the correction of any Benefit Plan defects under the IRS Employee
Benefits Compliance Resolution System, Department of Labor Voluntary Fiduciary Correction program,
Department of Labor Delinquent Filer Program or any other voluntary correction program. Each of
the Benefit Plans and each related trust agreement, annuity contract or other funding instrument
is, and has at all times been, in compliance in all material respects with its terms and the
applicable provisions of ERISA and the Code, except

25

 

***Text Omitted and Filed Separately with the Securities and Exchange

Commission. Confidential Treatment Requested Under

17 C.F.R. Sections 200.80(b)(4) and 240.24b-2

where the failure to comply would not have a Material Adverse Effect on the Company. Each
Benefit Plan that is subject to Section 401(a) or 408, as applicable, of the Code and each related
trust agreement, annuity contract or other funding instrument is qualified and tax exempt under the
applicable provisions of the Code. No Benefit Plan is a Multiemployer Plan, nor has the Company or
any ERISA Affiliate incurred any withdrawal liability with respect to any Multiemployer Plan or any
liability in connection with the termination or reorganization of any Multiemployer Plan. Except
as otherwise set forth on Schedule 3.11, all contributions, premiums or payments under or
with respect to each Benefit Plan are current and will have been paid as of the Closing Date or
accrued on the Closing Date Balance Sheet. For this purpose, “current” and “accrued” shall include
pro rata contributions, premiums and payments to each Benefit Plan for that portion of a plan year
or other applicable period that precedes the Closing Date. No action is pending or, to the
Sellers’ Knowledge, threatened with respect to any Benefit Plan (other than claims for benefits in
the ordinary course) and, to the Sellers’ Knowledge, no fact or event exists that could give rise
to any such action.

     Except as otherwise set forth on Schedule 3.11, neither the execution of this
Agreement nor the consummation of the transactions contemplated hereby will result in any payment
(whether for separation pay or otherwise) becoming due from any of the Sellers, the Company or any
ERISA Affiliate to any current or former employee, director, or consultant, or result in the
vesting, acceleration of payment or increase in the amount of any benefit payable to or in respect
of any such current or former employee, director, or consultant of any of the Sellers, the Company
or any ERISA Affiliate. Other than agreements for which the Company will obtain the necessary
stockholder approval pursuant to Section 7.10, there is no contract, agreement, plan or
arrangement covering any current or former employee, director, or consultant of the Sellers, the
Company or any ERISA Affiliate that individually or collectively could give rise to the payment of
any amount that would not be deductible pursuant to the terms of Sections 162(a)(1), 162(m), and/or
280G of the Code or would require the payment of an excise tax imposed by Section 4999 of the Code
or of any “gross up” of any such excise tax. None of the Benefit Plans provides for payment of
“parachute payments” (as defined in Section 280G(b)(2) of the Code), separation, severance,
termination or similar type benefits to any person or obligates the Sellers or the Company to pay
separation, severance, termination or similar type benefits solely as a result of any transaction
contemplated by this Agreement or as a result of an event occurring under
Section 280G(b)(2)(A)(i) of the Code. Except as required by applicable Legal Requirements, none of
the Benefit Plans provides for or promises retiree medical, disability or life insurance benefits
for any current or former employee, officer or director of the Company or any ERISA Affiliate or
provides continuation coverage to any individual following termination of employment or service
with the Company. Neither the Sellers nor any ERISA Affiliate have the right to modify or
terminate any Benefit Plan that provides coverage or benefits for either or both retired and active
employees and/or their beneficiaries. Each of the Benefit Plans is subject only to the laws of the
United States or a political subdivision thereof. No Benefit Plan is an “employee stock ownership
plan” (as defined in Section 4975(e)(7) of the Code) or a plan that is or was subject to Title IV
of ERISA, Section 412 of the Code or Section 302 of ERISA.

     All persons classified by the Company as independent contractors satisfy and have at all times
satisfied the requirements of applicable law to be so classified; the Company has fully and
accurately reported their compensation on IRS Forms 1099 when required to do so; and the

26

Commission. Confidential Treatment Requested Under

17 C.F.R. Sections 200.80(b)(4) and 240.24b-2

Company has no obligations to provide benefits with respect to such persons under Benefit
Plans or otherwise. The Company does not employ and has not employed any “leased employees” as
defined in Section 414(n) of the Code.

     Each Benefit Plan that is subject to Section 409A of the Code has been maintained and operated
in good faith based on the proposed or final regulations (as permitted by applicable guidance) and
related IRS guidance issued and in effect with respect to Section 409A of the Code and has been, or
will be prior to the Closing Date, amended to comply with Section 409A of the Code, and no Benefit
Plan subject to Section 409A of the Code would, as a result of its form, trigger the imposition of
penalty taxes under Section 409A of the Code.

     There has been no prohibited transaction (within the meaning of Section 406 of ERISA or
Section 4975 of the Code) with respect to any Benefit Plan (for which an exemption does not exist
under Section 408 of ERISA or Section 4975(d) of the Code), which could result in the imposition of
any material liability on the Company. Neither the Company nor any ERISA Affiliate has incurred
any liability for any material penalty or tax arising under Section 4971, 4972, 4980, 4980B or 6652
of the Code or any material liability under Section 502 of ERISA, and, to the Sellers’ Knowledge,
no fact or event exists which could give rise to any such liability. To the Sellers’ Knowledge,
none of Sellers, the Company nor any ERISA Affiliate has participated in a violation of Part 4 of
Title I, Subtitle B of ERISA by any fiduciary of a Benefit Plan or has any unpaid civil penalty
under Section 502(l) of ERISA.

notice, all books and records, information and employees (without substantial disruption of
employment) retained and remaining in existence after the Closing Date that are necessary or useful

          9.4 Employee Benefit Arrangements.

     Buyer shall have no liability with respect to any of the Benefit Plans and the Sellers and the
Company shall terminate all Benefit Plans sponsored by the Company immediately prior to the Closing
Date or take all necessary action to cause the Company to cease to be a participating employer in
any Benefit Plans sponsored by the Sellers. However, for a period of at least one year after the
Closing Date, for so long as the Surviving Corporation continues to employ an individual who was an
employee of the Company at Closing, Buyer agrees to cause the Surviving Corporation to pay to such
employee substantially similar compensation (including base salary and a comparable bonus plan, but
excluding equity or phantom equity awards and 401(k) match contributions) as that paid by the
Company to such employee immediately prior to the Closing, and to provide such employee with Buyer
benefits that are substantially similar in the aggregate to the benefits provided to such employee
under the Benefit Plans immediately prior to the Closing. In addition, Buyer shall cause the
Surviving Corporation to (a) grant credit to each employee of the Company for all unused vacation
and sick leave existing as of the Closing and (b) recognize service with the Company prior to the
Closing as deemed service with the Surviving Corporation for purposes of any length of service
requirements, waiting periods, vesting periods (other than with respect to any Buyer equity
incentives) and differential benefits based on length of service, and with credit under any welfare
benefit plan for any deductibles or co-insurance paid for the current plan year under any plan
maintained by the Company, to the extent permitted by such plan. To the extent any amounts payable
to or for the benefit of the employees of the Company with respect to any Benefit Plan or otherwise
is set forth on the Closing Date Balance Sheet, Buyer agrees to cause the Surviving Corporation to
pay such amounts to or for the benefit of the employees of the Company. In the event that the
Buyer or the Surviving Corporation terminates any employee after the Closing without cause, the
Buyer shall be responsible for the payment of any applicable Buyer Severance Expenses.

          9.5 Cooperation on Tax Matters; Transfer Taxes.

     (a) The Sellers shall cause to be prepared and submit to the Buyer for timely filing all Tax
Returns of the Company for the taxable periods ending on or prior to the Closing Date
(“Pre-Closing Tax Period”) that are due after the Closing Date and Sellers shall pay any
Taxes due thereon. After the Closing and in connection with the preparation of any such Tax
Returns, Buyer and the Surviving Corporation shall grant or cause to be granted to the Sellers, or
their representatives, access to all of the information, books and records relating to the Company
within Buyer’s or the Surviving Corporation’s possession or control and shall furnish the
assistance and cooperation of such personnel of Buyer and the Surviving Corporation as may
reasonably be requested in connection therewith. Sellers shall be entitled to any credits or
refunds of income Taxes of the Company with respect to any taxable periods of the Company ending
before the Closing Date. Buyer shall prepare or cause to be prepared and file or cause to be filed
any Tax Returns of the Surviving Corporation for periods that end after the Closing Date; it being
understood that all Taxes shown as due and payable on such Tax Returns shall be the responsibility
of Buyer. The Parties further agree and acknowledge that (i) the Company’s Transaction Expenses not
subject to capitalization shall be expenses of the Company reported on its Tax Returns for the
short taxable year ending on the Closing Date, and (ii) neither the

53

 

***Text Omitted and Filed Separately with the Securities and Exchange

Commission. Confidential Treatment Requested Under

17 C.F.R. Sections 200.80(b)(4) and 240.24b-2

Surviving Corporation nor Buyer shall deduct the Company’s Transaction Expenses not subject to
capitalization on any Tax Return for any taxable period beginning after the Closing Date.

     (b) The Sellers shall be liable for, and shall pay any and all transfer, sales, use, excise,
goods and services, health services, conveyance, recording or any other similar fees or Taxes
(including, without limitation, title recording or filing fees, transfer Taxes and other amounts
payable in respect of transfer filings), and all documentary or other stamp Taxes, arising out of
or related to the Merger and the other transactions contemplated by this Agreement. The Parties
shall consult with each other in good faith and shall cooperate fully with each other in planning
for the reduction or elimination of any such Taxes.

     (c) If a claim for Taxes, including, without limitation, notice of a pending or threatened
audit, shall be made by any Taxing Authority in writing (a “Tax Claim”), which, if
successful, might result in an indemnity payment pursuant to this Agreement, the party seeking
indemnification (the “Tax Indemnified Party”) shall notify the other party (the “Tax
Indemnifying Party”) in writing of the Tax Claim within 15 business days of receipt of such Tax
Claim. If notice of a Tax Claim (a “Tax Notice”) is not given to the Tax Indemnifying
Party within such 15 day period, the Tax Indemnifying Party shall not be liable to the Tax
Indemnified Party to the extent the Tax Indemnified Party was materially prejudiced by such delay.
The Sellers shall have the sole right to represent the interests of the Surviving Corporation in
any Tax audit or administrative or court proceeding relating to the Pre-Closing Tax Period, and to
employ counsel of their choice; provided, however, if any issue or potential
adjustment in such proceeding would or could result in an increase in the Surviving Corporation’s
Taxes for any period following the Closing Date, then the Surviving Corporation shall have the
right to participate in such proceeding (as it relates to such issue or adjustment) and Sellers
shall not be entitled to settle or compromise such issue or adjustment without the prior consent of
the Surviving Corporation. If the Sellers decide not exercise such right, the Sellers shall be
entitled to participate in the defense of any claim for Taxes for the Pre-Closing Tax Period that
may be subject to indemnification by the Sellers pursuant to this Section 9.5.
Notwithstanding the foregoing, neither Buyer nor the Surviving Corporation shall be entitled to
settle, either administratively or after the commencement of litigation, any claim for Taxes that
would result in a claim for indemnification pursuant to Section 9.5 without the prior
written consent of the Stockholder Representative.

     (d) Until the Closing Date, the Company shall not make or change any material election in
respect to Taxes, adopt or change any accounting method in respect to Taxes, enter into any closing
agreement settle any claim or assessment in respect of Taxes, file any amended Tax return,
surrender any refund claim, or consent to any extension or waiver of the limitation period or
period of assessment or reassessment applicable to any claim or assessment in respect of Taxes,
except with the prior written consent of Buyer, which consent shall not be unreasonably withheld or
delayed.

     (e) The Stockholder Representative shall be entitled, where permitted by law, to elect to
carry back to a Pre-Closing Tax Period or Periods any net operating loss, net capital loss,
charitable contribution or other Tax item attributable to the Pre-Closing Tax Period. In
connection therewith, the Buyer or the Surviving Corporation shall permit the Stockholder

Representative to control the prosecution of any such refund claim at the Sellers’ expense
and, where deemed appropriate by the Stockholder Representative, shall cause the Surviving
Corporation and any of its successors to authorize by appropriate powers of attorney such persons
as the Stockholder Representative shall designate to represent the Surviving Corporation or any of
their successors with respect to such refund claim. Any refunds or credits of Taxes of the Company
received from the applicable Taxing Authority for the Pre-Closing Tax Period (including, without
limitation, refunds or credits arising by reason of amended Tax Returns filed after the Closing
Date) shall be for the account of the Sellers and shall be paid by Buyer or the Surviving
Corporation to the Stockholder Representative within 10 days after Buyer or the Surviving
Corporation receives such refund or after the relevant Tax Return is filed in which the credit is
applied against the Surviving Corporation’s or Buyer’s or their Affiliates’ liability for Taxes.

     (f) Except for the offset rights set forth in Section 11.8, this Section 9.5
shall govern the procedures with respect to Taxes. Notwithstanding any provision of this Agreement
to the contrary, the covenants, agreements and obligations of the Parties in this Section
9.5 shall survive the Closing.

          9.6 Restrictive Covenants.

     (a) Each Seller covenants that, during the Noncompetition Period, such Seller shall not, and
it shall cause its Affiliates not to, directly or indirectly, in any capacity, work for, engage in
or have any direct or indirect ownership interest in, or permit such Seller’s or any such
Affiliate’s name to be used in connection with, any business anywhere in the United States which is
engaged, either directly or indirectly, in the business of developing, marketing or selling any
dermatologic products that are competitive with products manufactured, marketed, and sold by, or
services provided by, the Company as of the Effective Date; provided, however, such
Seller and its Affiliates shall be able to sell skin products in the acute care (i.e., hospital,
wound care clinics, surgery centers, outpatient clinics and home health) and extended care (i.e.,
nursing home and retirement home) markets as well as wound care products in the dermatology market
for the treatment, prevention or healing of wounds; and, provided further, such
Seller and its Affiliates shall continue to have the ability to manufacture and perform research
and development and other services related to such products as well as dermatologic products of any
kind or nature, including dermatologic products substantially similar to and in direct competition
with any of the Company Products or future products to be developed by the Buyer or its Affiliates,
provided that the Sellers do not use or otherwise disclose any Company Intellectual Property in the
process of performing and/or providing such services, and provided further, that
such manufacturing, research and development activities or other related services are for the sole
benefit of and on behalf of unaffiliated independent third parties (the “Restricted
Business”). It is recognized that the Restricted Business is expected to be conducted
throughout the United States and that more narrow geographical limitations of any nature on this
non-competition covenant (and the non-solicitation covenant set forth in Section 9.6(b))
are therefore not appropriate.

     (b) Each Seller covenants that, commencing on the Closing Date and for a period of 24 months
after the Closing Date, such Seller shall not, and it shall cause its Affiliates not to,

55

 

 ***Text Omitted and Filed Separately with the Securities and Exchange

solicit the employment or engagement of services of any person who is or was employed as an
employee, consultant or contractor of the Company on the Effective Time or at any time within the
twelve (12) months preceding the Effective Time; provided, however, the Sellers and
their Affiliates shall be permitted to (i) solicit the employment or engagement of services of any
such person who is affirmatively terminated by the Surviving Corporation after the Closing Date,
(ii) solicit the employment or engagement of services of any such person who resigns from the
Surviving Corporation if such person is required by the Surviving Corporation to relocate to a
place of employment that is more than 30 miles away from their place of employment as of the
Effective Time, (iii) engage in any advertisement for, or general solicitation of, employment that
is not specifically targeted at such persons or (iv) hire any such person who responds to any
solicitation permitted by clause (i), clause (ii) or clause (iii); and provided
further, that the Surviving Corporation shall not be obligated to pay severance to any
employee hired by any Seller or their Affiliates, as permitted by this Section 9.6, during
the period in which such employee is also employed by any Seller or its Affiliates.

     (c) The Sellers acknowledge that the restrictions contained in this Section 9.6 are
reasonable and necessary to protect the legitimate interests of the Buyer and constitute a material
inducement to Buyer to enter into this Agreement and consummate the transactions contemplated by
this Agreement. The Sellers acknowledge that any violation of this Section 9.6 will result
in irreparable injury to Buyer and agree that Buyer shall be entitled to preliminary and permanent
injunctive relief without the necessity of proving actual damages.

     (d) In the event that any covenant contained in this Section 9.6 should ever be
adjudicated to exceed the time, geographic, product or service or other limitations permitted by
applicable Legal Requirements in any jurisdiction, then any court is expressly empowered to reform
such covenant, and such covenant shall be deemed reformed, in such jurisdiction to the maximum
time, geographic, product or service or other limitations permitted by applicable Legal
Requirements. The covenants contained in this Section 9.6 and each provision thereof are
severable and distinct covenants and provisions. The invalidity or unenforceability of any such
covenant or provision as written shall not invalidate or render unenforceable the remaining
covenants or provisions hereof, and any such invalidity or unenforceability in any jurisdiction
shall not invalidate or render unenforceable such covenant or provision in any other jurisdiction.

          9.7 Confidential Information.

               The Sellers covenant that they shall, and shall cause their Affiliates to, hold confidential
all Company Intellectual Property and all other proprietary technical, financial and business
information relating to the Company, which may include, but is not limited to, technical data,
trade secrets, know-how, intellectual property or other materials owned or controlled by the
Company at the time of Closing, including, but not limited to, research, product plans, products,

performed by such Party or its Affiliates at or prior to the Closing);

     (c) by written notice from Buyer to the Company if the transactions contemplated hereunder
shall not have been consummated by the End Date (unless the failure to consummate the transactions
contemplated hereunder is attributable to the breach of any representations or a failure on the
part of Buyer or its Affiliates to perform any obligation required to be performed by Buyer or its
Affiliates at or prior to the Closing);

     (d) by written notice from Buyer to the Company, unless Buyer is then in material default or
breach of this Agreement, following a material breach of any covenant or agreement of the Sellers
or the Company contained in this Agreement, or if any representation or warranty of the Sellers
contained in this Agreement shall be or shall have become inaccurate, in either case such that any
of the conditions set forth in Section 7.1 and Section 7.2 would not be satisfied
as of the time of such breach or as of the time such representation or warranty was or shall have
become inaccurate; provided, however, that: (i) if such breach or inaccuracy is
curable by the Sellers or the Company, then Buyer may not terminate this Agreement under this
Section 10.1(d) with respect to the particular breach or inaccuracy provided the Sellers or
the Company cures such breach or inaccuracy within thirty (30) days after written notice of such
breach from Buyer is received by the Company; and (ii) the right to terminate this Agreement under

Section 10.1(d) shall not be available to Buyer if the breach is the result of any
willful act on the part of Buyer designed to impede the consummation of any transaction
contemplated hereby; or

     (e) by written notice from the Company to Buyer, unless the Company or any Seller is then in
material default or breach of this Agreement, following a material breach of any covenant or
agreement of Buyer or Newco contained in this Agreement, or if any representation or warranty of
Buyer contained in this Agreement shall be or shall have become inaccurate, in either case such
that any of the conditions set forth in Section 8.1 and Section 8.2 would not be
satisfied as of the time of such breach or as of the time such representation or warranty was or
shall have become inaccurate; provided, however, that: (i) if such breach or
inaccuracy is curable by Buyer or Newco, then the Company may not terminate this Agreement under
this Section 10.1(e) with respect to the particular breach or inaccuracy provided Buyer or
Newco cures such breach or inaccuracy within thirty (30) days after written notice of such breach
from the Company is received by Buyer and (ii) the right to terminate this Agreement under this
Section 10.1(e) shall not be available to the Company if the breach is the result of any
willful act on the part of the Company or the Sellers designed to impede the consummation of any
transaction contemplated hereby.

Notwithstanding the foregoing, in the event that, as of the End Date, all conditions to the
obligations of the Parties set forth in Article 7 and Article 8 have been satisfied
or waived (other than those that are to be satisfied by action taken at the Closing) other than the
condition that all Governmental Authorizations or waiting periods following governmental filings
required under the HSR Act have been obtained or expired (as set forth in Section 7.4 and
Section 8.4), then the End Date shall automatically be extended to January 15, 2009.

          10.2 Effect of Termination.

     In the event of any termination of this Agreement pursuant to Section 10.1, this
Agreement shall immediately become void and there shall be no liability or obligation on the part
of any Party to consummate the transactions contemplated hereby; provided, however,
that (a) no such termination shall relieve any Party from liability for damages arising out of or
with respect to the breach of this Agreement by such Party prior to such termination and (b) the
confidentiality provisions of Section 6.2, and the expense responsibility provisions of
Section 12.12 shall remain in full force and effect and survive any termination of this
Agreement.

3.[...***...],
Section 3.[...***...] and

agreements made by the Parties in this Agreement shall survive the execution and delivery of this
Agreement and the Closing and continue in full force and effect thereafter for the time period
specified in the respective covenant or, if no time period is specified, for so long as such
covenants remain executory in nature. Notwithstanding anything to the contrary contained in this
Agreement, no claim with respect to a breach of any representation or warranty may be asserted nor
any action commenced against any Party obligated to provide indemnification pursuant to this
Article 11 unless written notice describing in reasonable detail the facts and
circumstances with respect to the subject matter of such claim or action is received by such Party
on or prior to the date on which the representation or warranty on which such claim or action is
based ceases to survive as set forth in this Section 11.1; provided,
however, that any written notice of a claim submitted in accordance herewith (including the
requirement that the facts and circumstances of such claim be described in reasonable detail) shall
be deemed to preserve the subject matter of such claim for indemnification for purposes hereof even
if the Losses attributable to such claim have not, as of the date the claim is submitted, been paid
or even definitively quantified so long as the amount of such claim has been accrued for, in
accordance with GAAP, on the balance sheet of the party suffering such Losses.

          11.2 Indemnification by the Sellers.

     (a) Subject to the limitations set forth below, including specifically, the limitations
contained in Section 11.2(b), Section 11.2(c) and Section 11.2(d), the
Sellers agree, subject to the other terms and conditions of this Article 11, to indemnify,
defend and hold harmless Buyer and Newco (and with respect to any period after the Effective Time,
the Surviving Corporation), and each of their respective directors, officers, employees and
Affiliates (collectively, the “Buyer Indemnitees”), from and against any and all Losses
incurred or suffered by any such Buyer Indemnitee that are related to or arise, directly or
indirectly, out of (i) the breach of any representation or warranty of the Sellers contained in
Article 3 of this Agreement or in any certificate delivered by the Stockholder
Representative at the Closing pursuant to Section 7.1 as it related to such representations
and warranties, (ii) any breach by the Sellers of any covenants or agreements to be performed by
the Sellers pursuant to this Agreement, (iii) any breach by the Company of any covenants or
agreement to be performed by it pursuant to this Agreement on or prior to the Closing Date,
(iv) [...***...] arising from the
[...***...] or [...***...] of the
[...***...] or [...***...] of the [...***...] prior to

Company that would have constituted a breach of any representation and warranty of the Sellers
contained in Article 3 of this Agreement if the Company had been formed prior to the
occurrence of such facts, which facts are not otherwise rectified prior to the Closing Date, (vi)
any claim made by any Seller or any Affiliate of any Seller against the Company relating to facts
arising prior to the Closing, (vii) any Third Party Claim for

17 C.F.R. Sections 200.80(b)(4) and 240.24b-2

arising out of or in connection with the transactions contemplated hereby, shall consist
solely of (i) the rights of the Buyer Indemnitees to indemnification by the Sellers (including the
Individual Sellers), subject to the limitations set forth in Section 11.2(d), for any
Losses indemnifiable under Section 11.2(a) solely from funds held by the Escrow Agent
pursuant to the Indemnity Escrow Agreement, (ii) the rights of the Buyer Indemnitees to
indemnification by DFB, subject to the limitations set forth in Section 11.2(d), for any
Losses indemnifiable under Section 11.2(a), (iii) the right to pursue any available
remedies at law or in equity against any Seller for any fraud or intentional misrepresentation
committed by such Seller and (iv) the right to pursue specific performance and other equitable
remedies for any matter that is indemnifiable under Section 11.2(a)(ii) or
Section 11.2(a)(iii). In no event shall any Buyer Indemnitee or any other Person be
entitled to punitive damages or the like for any breach of any term hereunder.

     (c) Notwithstanding anything to the contrary contained in this Agreement, no Individual Seller
shall be liable for any indemnity obligation under this Section 11.2 or under any other
provision of this Agreement or for any other liability otherwise arising out of or in connection
with the transactions contemplated hereby, except that each Individual Seller shall be severally,
and not jointly and severally, liable for his or her own fraud or intentional misrepresentation in
an amount not to exceed the Merger Consideration received by such Individual Seller.

     (d) The indemnification obligations of the Sellers pursuant to Section 11.2(a) shall
not be effective until the aggregate dollar amount of all Losses that would otherwise be
indemnifiable pursuant thereto exceeds $[...***...] (the “Deductible”), and then only to the
extent such aggregate amount of Losses exceeds the Deductible; provided, however,
in the case of (i) fraud or intentional misrepresentation or (ii) an indemnity claim with respect
to any Unlimited Representation, the Deductible shall not apply. The indemnification obligations
of the Sellers pursuant to Section 11.2(a) shall be limited, in the aggregate, to $[...***...]
(the “Sellers Cap”), and no indemnification pursuant to such provisions shall be payable in
excess of the Sellers Cap; provided, however, that in the case of (A) fraud or
intentional misrepresentation or (B) an indemnity claim with respect to any Unlimited
Representation, the Sellers Cap shall not apply and such aggregate limitation on indemnification
shall be 100% of the Merger Consideration. For so long as the Indemnity Escrow Agreement is in
effect and to the extent that sufficient funds are held pursuant thereto, the Buyer Indemnitees
shall first make a claim against the funds held pursuant to the Indemnity Escrow Agreement in
accordance with its terms for payment of any indemnification obligation to which any Buyer
Indemnitee is entitled pursuant to Section 11.2(a).

     (e) The Sellers shall have no obligation to indemnify the Buyer Indemnitees with respect to
any liabilities or assets of the Company (or the Surviving Corporation) to the extent included as a
liability in the calculation of the Adjusted Net Working Capital, as finally determined under the
procedures set forth in Section 2.5.

     (f) If an indemnification obligation exists under Section 11.2(a) due to the
inaccuracy of any representation or warranty or breach of any covenant under this Agreement, the
amount of any Losses related to such inaccuracy will be calculated without regard to any
qualifications as to materiality or Material Adverse Effect contained in such representation or
warranty or

covenant; provided, however, that no individual claim by a Buyer Indemnitee
may be asserted, and the Sellers shall have no indemnification obligation under Section
11.2(a)(i) with respect to any such claim for breach of representation or warranty qualified by
materiality or Material Adverse Effect, unless the aggregate amount of Losses that would be payable
with respect to such claim exceeds an amount equal to $[...***...] (it being understood that similar
individual claims will be aggregated for purposes of this Section 11.2(f)).

          11.3 Indemnification by Buyer.

     (a) Buyer agrees, subject to the other terms and conditions of this Article 11, to
indemnify, defend and hold harmless the Company (prior to the Closing), each Seller and their
respective directors, officers, employees and Affiliates (collectively, the “Seller
Indemnitees”), from and against any and all Losses incurred or suffered by any such Seller
Indemnitee that are related to or arise, directly or indirectly, out of (i) the breach of any
representation or warranty of Buyer contained in Article 4 of this Agreement or in any
certificate delivered by Buyer at the Closing pursuant to Section 8.1 as it related to such
representations and warranties and (ii) any breach by Buyer or Newco (or with respect to any period
after the Effective Time, the Surviving Corporation) of any covenants or agreements to be performed
by such Person pursuant to this Agreement.

     (b) Notwithstanding anything to the contrary contained in this Agreement, the sole and
exclusive remedies of the Seller Indemnitees or any other Person for any breach by Buyer or Newco
(or with respect to any period after the Effective Time, the Surviving Corporation) of any
provision of this Agreement, or otherwise arising out of or in connection with the transactions
contemplated hereby, shall consist solely of (i) the rights of the Seller Indemnitees to
reimbursement by Buyer, subject to the limitations set forth in Section 11.3(c), for any
Losses indemnifiable under Section 11.3(a), (ii) the right to pursue any available remedies
at law or in equity against Buyer for any fraud or intentional misrepresentation committed by Buyer
and (iii) the right to pursue specific performance and other equitable remedies for any matter that
is indemnifiable under Section 11.3(a)(ii). In no event shall any Seller Indemnitee or any
other Person be entitled to punitive damages or the like for any breach of any term hereunder.

     (c) The indemnification obligations of Buyer pursuant to Section 11.3(a) shall not be
effective until the aggregate dollar amount of all Losses that would otherwise be indemnifiable
pursuant thereto exceeds the Deductible, and then only to the extent such aggregate amount of
Losses exceeds the Deductible; provided, however, in the case of fraud or
intentional misrepresentation or in the case of an indemnity claim under Section 4.1 or
Section 4.2, the Deductible shall not apply. The indemnification obligations of Buyer
pursuant to Section 11.3(a) shall be limited, in the aggregate, to $[...***...] (the “Buyer
Cap”), and no indemnification pursuant to such provisions shall be payable in excess of the
Buyer Cap; provided, however, that in the case of fraud or intentional
misrepresentation, the Buyer Cap shall not apply and such aggregate limitation on indemnification
shall be 100% of the Merger Consideration.

     (d) If an indemnification obligation exists under Section 11.3(a) due to the
inaccuracy of any representation or warranty or breach of any covenant under this Agreement, the
amount of any Losses related to such inaccuracy will be calculated without regard to any
qualifications as

***Text Omitted and Filed Separately with the Securities and Exchange

Commission. Confidential Treatment Requested Under

17 C.F.R. Sections 200.80(b)(4) and 240.24b-2

to materiality or Material Adverse Effect contained in such representation or warranty or
covenant; provided, however, that no individual claim by a Seller Indemnitee may be
asserted, and Buyer and Newco (and with respect to any period after the Effective Time, the
Surviving Corporation) shall have no indemnification obligation under Section 11.3(a)(i)
with respect to any such claim for breach of representation or warranty qualified by materiality or
Material Adverse Effect, unless the aggregate amount of Losses that would be payable with respect
to such claim exceeds an amount equal to $[...***...] (it being understood that similar individual
claims will be aggregated for purposes of this Section 11.3(d)).

          11.4 Notice of Potential Claims for Indemnification.

     Except as otherwise provided in Section 9.5(c), a party entitled to indemnification
under Section 11.2 or Section 11.3 (the “Indemnitee”) shall give the party
obligated to provide such indemnification (the “Indemnifying Party”) prompt written notice
(an “Indemnification Notice”) of any matter or event that could give rise to any Losses for
which indemnification under this Article 11 may be due, including but not limited to any
Third Party Claim, which, with the lapse of time, the giving of notice or both, would give rise to
a claim or the commencement of any litigation that may result in Losses (an “Asserted
Liability”). Each Indemnification Notice shall specify with particularity the basis on which
indemnification is sought and the Indemnitee’s good faith estimate of the amount of its Losses
and/or Asserted Liability and, in the case of a Third Party Claim, contain (by attachment or
otherwise) all such other information as such Indemnitee may have concerning such Third Party
Claim. After the delivery of an Indemnification Notice, the Indemnitee shall provide prompt
written notice to the Indemnifying Party of all developments relating to the related Losses or
Asserted Liability and any material changes in the Indemnitee’s good faith estimate of the amount
of its Losses or Asserted Liability. The Indemnitee shall provide the Indemnifying Party with
access, upon reasonable notice and during normal business hours, to its books and records,
properties and personnel relating to the Losses or Asserted Liability. The Indemnitee will not be
entitled to indemnification for Losses or Asserted Liabilities of the Indemnitee to the extent that
any unreasonable delay in providing an Indemnification Notice or notice of future developments or
other failure to follow the procedures set forth in this Article 11 prejudices the
Indemnifying Party’s ability to defend a Third Party Claim or otherwise affects the Indemnifying
Party’s ability to reduce the amount of indemnifiable Losses.

          11.5 Claims Not Involving Third Parties.

     Upon receipt of an Indemnification Notice not involving a Third Party Claim, the Indemnifying
Party shall have twenty (20) business days to object to the claim set forth in the Indemnification
Notice by delivery of a written objection (an “Objection”) to the Indemnitee specifying in
reasonable detail the basis for such objection. Failure to timely deliver an Objection shall
constitute a final and binding acceptance of the claim by the Indemnifying Party. If the
Indemnifying Party timely delivers an Objection, the parties shall in good faith seek to resolve
any dispute within the twenty (20) business day period following the Objection (the “Dispute
Resolution Period”). If the parties have not resolved their dispute within the Dispute
Resolution Period, either Party may bring an action pursuant to Section 12.8 and the
parties shall proceed in accordance therewith. Upon resolution of a dispute and the determination
of indemnifiable Losses pursuant to a final, non-appealable order in favor of an Indemnitee, such
Indemnitee shall be entitled to be paid

Commission. Confidential Treatment Requested Under

by the Indemnifying Party an aggregate amount equal to such Losses within five (5) business
days of such order by wire transfer of immediately available funds to such account as such
Indemnitee may specify in writing to the Indemnifying Party.

          11.6 Third Party Claims.

     The obligations and liabilities of an Indemnifying Party hereunder with respect to a Third
Party Claim for which an Indemnitee is entitled to indemnification pursuant to this Article
11 shall be subject to the terms and conditions set forth in this Article 11. An
Indemnifying Party shall have the right to contest any Asserted Liability so long as it shall
within thirty (30) days (or sooner, if the nature of the Asserted Liability so requires) notify the
Indemnitee of its intent to do so by sending a notice to the Indemnitee. An Indemnifying Party
shall not consent to the entry of any judgment or enter into any settlement with respect to the
Asserted Liability without the prior written consent of the Indemnitee, which consent shall not
unreasonably be withheld. So long as the Indemnifying Party is contesting any Asserted Liability,
the Indemnitee shall not consent to the entry of any judgment or enter into any settlement with
respect to the Asserted Liability. If the Indemnifying Party elects not to contest the Asserted
Liability, the Indemnitee (upon further notice to the Indemnifying Party) shall have the right to
pay, compromise or contest such Asserted Liability, provided that Indemnitee obtains the prior
written consent of the Indemnifying Party, which consent shall not unreasonably be withheld. In
any event, the Indemnifying Party and the Indemnitee may participate, at their own expense, in the
contest of an Asserted Liability. The Indemnifying Party and the Indemnitee shall cooperate fully
with each other as to all Asserted Liabilities, shall make available to each other as reasonably
requested all information, records, and documents relating to all Asserted Liabilities and shall
preserve all such information, records, and documents until the termination of any Asserted
Liability.

          11.7 Subrogation.

     Upon payment of any Losses or the payment of any judgment or settlement with respect to a
Third Party Claim, the Indemnifying Party shall be subrogated to the extent of such payment to the
rights of the Indemnitee against any person or entity with respect to the subject matter of such
Losses or Third Party Claim. The Indemnitee shall assign or otherwise cooperate with the
Indemnifying Party, at the cost and expense of the Indemnifying Party, to pursue any claims
against, or otherwise recover amounts from, any Person liable or responsible for any Losses for
which indemnification has been received pursuant to this Agreement.

          11.8 Insurance and Other Recoveries.

     Losses and all indemnification payments payable hereunder shall be reduced by the amount of
insurance proceeds actually received by the Indemnitee or its Affiliates (net of any applicable
deductible) as a result of the Losses for which the Indemnitee is seeking indemnification.

          11.9 Acknowledgement of Buyer.

     Buyer acknowledges that it has (a) conducted to its satisfaction an independent investigation
and verification of the financial condition, results of operations, assets, liabilities, properties
and projected operations of the Company and (b) relied on the results of its own independent

63

 

***Text Omitted and Filed Separately with the Securities and Exchange

Commission. Confidential Treatment Requested Under

investigation and verification and the representations and warranties of the Sellers expressly
and specifically set forth in this Agreement, including the Disclosure Schedules (and updated
Disclosure Schedules), in making its determination to proceed with the transactions contemplated by
this Agreement. The representations and warranties of the Sellers expressly and specifically set
forth in this Agreement, including the Disclosure Schedules (and updated Disclosure Schedules),
constitute the sole and exclusive representations and warranties of the Sellers and the Company to
Buyer in connection with the transactions contemplated hereby, and Buyer understands, acknowledges
and agrees that all other representations and warranties of any kind or nature expressed or implied
(including, but not limited to, any relating to the future or historical financial condition,
results of operations, assets or liabilities of the Company, or the quality, quantity or condition
of the Company’s assets) are specifically disclaimed by the Sellers (on behalf of themselves and
the Company). The Sellers and the Company do not make or provide, and Buyer hereby waives, any
warranty or representation, express or implied, as to the quality, merchantability, fitness as for
a particular purpose, conformity to samples, or condition of the Company’s assets or any part
thereto, except as expressly set forth in Section 3.7. In connection with Buyer’s
investigation of the Company, Buyer has received certain projections, pro forma financials or
adjustments, including projected statements of operating revenues and income from operations of the
Company and certain business plan information. Buyer acknowledges that there are uncertainties
inherent in attempting to make such estimates, projections, forecasts, pro forma financials,
adjustments and plans, that Buyer is familiar with such uncertainties and that Buyer is taking full
responsibility for such estimates, projections, forecasts, pro forma financials, adjustments and
plans so furnished to it, including, without limitation, the reasonableness of the assumptions
underlying such estimates, projections, forecasts, pro forma financials, adjustments and plans
Accordingly, Buyer hereby acknowledges that neither the Company nor the Sellers is making any
representation or warranty with respect to such estimates, projections, forecasts, pro forma
financials, adjustments and plans, including, without limitation, the reasonableness of the
assumptions underlying same.

          11.10 Stockholder Representative.

     Each of the Sellers hereby appoint DFB or its agents, successors or assigns as their exclusive
agent and attorney-in-fact to act on its behalf with respect to any claims, controversies, or
disputes arising out of the terms of this Agreement (the “Stockholder Representative”).
The Sellers further agree that the Stockholder Representative shall have the power to (a) receive
all notices and communications directed to the Sellers with respect to any claims, controversies,
or disputes arising out of the terms of this Agreement and to take any action or no action in
connection therewith as it may deem appropriate, and (b) to take any action (or determine to take
no action) with respect to the foregoing appointment and authority as it may deem appropriate as
effectively as the Sellers could act themselves, including the settlement or compromise of any
dispute or controversy under the indemnification provisions hereof, the Indemnity Escrow Agreement,
the Return Escrow Agreement or any other document entered into in connection herewith. The
authority granted hereunder is deemed to be coupled with an interest. For purposes of clarity, the
adoption of this Agreement by the Sellers constitutes approval of the appointment of DFB to serve
as the Sellers’ representative on such indemnification matters and to have sole power with respect
to the authorization of disbursements of funds from the Escrow Amounts to Buyer.

invalid, illegal or incapable of being enforced, the Parties hereto shall negotiate in good faith
to modify this Agreement so as to effect the original intent of the Parties as closely as possible
