Noteholders” and, together with the 1999 Noteholders, the “Noteholders”), of the $60,000,000 aggregate principal amount of 8.59% Senior Notes due November 21, 2008 issued and sold pursuant to a Note Agreement, dated as
of November 21, 2000 by and among Barnes and Purchasers listed in Schedule A attached thereto and as amended by Amendment No. 1 to the Note Agreement, dated as of February 21, 2002 and Amendment No. 2 to the Note Agreement, dated
as of February 5, 2003 (the “2000 Note Agreement”), hereby waive the provision of Section 7.7(b) of the 2000 Note Agreement which restricts Barnes’ ability to assume the obligations of 3031786. 
  
 1.6. Consent by Holder, Exchange of Notes, etc. 
  
 (a) Subject to Barnes’ satisfaction of each of the
conditions set forth in Section 3, each 2000 Noteholder, by its execution and delivery of this Assumption Agreement, agrees and consents to the Assumption, the Release and the Amendments and Restatements (its “Consent”).

  
 (b) On or before the Effective Date, Barnes
will deliver to the 1999 Noteholders’ special counsel, Bingham McCutchen LLP, One State Street, Hartford, CT 06103, one or more Notes, of the series and in the denominations specified below such 1999 Noteholder’s name on Schedule A hereto,
dated the date hereof, and payable to such 1999 Noteholder or as otherwise indicated on Schedule A hereto, against delivery by such 1999 Noteholders of the Existing Notes or before the Effective Date to Bingham McCutchen LLP, One State Street,
Hartford, CT 06103. On the Effective Date, Bingham McCutchen LLP will forward the Notes to the 1999 Noteholders as directed in Schedule A hereto and the Existing Notes to 3031786 for cancellation. All amounts owing under, and evidenced by, the
Existing Notes as of the Effective Date shall continue to be outstanding under, and shall after the Effective Date be evidenced by, the Notes, and shall be repayable in accordance with the Amended Note Agreement and the Notes. 
  
 1.7. Acquisition for Investment. 
  
 Each 1999 Noteholder hereby acknowledges that the Notes have not and will not
be registered or qualified under the Securities Act, any securities laws of any state of the United States of America, or the securities laws of any other applicable jurisdiction and such 1999 Noteholder represents to Barnes that it is acquiring the
Notes listed on Schedule A hereto below its name for its own account or for the account of one or more separate accounts maintained by it for investment and with no present intention or view of distributing or otherwise selling the 

  

 14 








 
Notes or any part thereof, but without prejudice to each such 1999 Noteholder’s right at all times to 
  
 (a) sell or otherwise dispose of all or any part of the
Notes 
  
 (i) under a registration statement
filed under the Securities Act and/or other applicable securities law, or 
  
 (ii) in a transaction exempt from the registration or qualification requirements of the Securities Act and other applicable securities laws, and 
  
 (b) have control over the disposition of all of its assets to the fullest extent required by any applicable
insurance law. 
  
 It is understood that, in making the
representations set out in Section 2.10, Barnes is relying, to the extent applicable, upon your representations in this Section 1.7. 
  
 1.8. Failure to Deliver, Failure of Conditions. 
  
 If on or before the Effective Date Barnes fails to tender to any 1999 Noteholder the Notes to be acquired by it on such date, or if the conditions
specified in Section 3 hereof to be fulfilled on or before the Effective Date have not been fulfilled, the 1999 Noteholders shall, at their election, be relieved of all further obligations under this Assumption Agreement, without thereby
waiving any rights the 1999 Noteholders may have by reason of such failure or such nonfulfillment, and the Existing Note Purchase Agreement and the Existing Notes shall remain in full force and effect and the Consent, the Assumption, the Release and
the Amendments and Restatements shall be of no force or effect. 
  
 1.9. Expenses.

Noteholders in connection with such transactions, including, without limitation:

Effective Date, the reasonable fees and the disbursements of the Noteholders’ special counsel pursuant to statements thereof presented prior to the Effective Date, and Barnes will also pay upon receipt of any statement thereof, any additional
reasonable fees and additional disbursements of such special counsel pursuant to any statement thereof rendered after the Effective Date in 

  

 15

other similar laws affecting the enforcement of creditors’ rights generally and (b) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

Section 8.1 of the Existing Note Purchase Agreement, since December 31, 2004, there has been no change in the financial condition, operations, business, properties or prospects of Barnes or any Subsidiary, except changes that individually
or in the aggregate would not reasonably be expected to have a Material Adverse Effect. There is no fact known to Barnes or 3031786 that would reasonably be expected to have a Material Adverse Effect that has not been set forth herein or in the
other documents, certificates and other writings delivered to the Noteholders by or on behalf of 3031786 or Barnes specifically for use in connection with the transactions contemplated hereby. 
  
 2.4. Compliance with Law, other Instruments, etc. 
  
 Neither (a) the execution, delivery and performance by 3031786 and
Barnes of this Assumption Agreement, nor (b) the execution, delivery and performance by Barnes of the Amended Note Agreement or the Notes, will 
  
 (i) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property
of Barnes or any Subsidiary under, any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, corporate charter or by-laws, or any other agreement or instrument to which Barnes or any Subsidiary is bound or by which Barnes or
any Subsidiary or any of their respective properties may be bound or affected, 
  
 (ii) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any
court, arbitrator or Governmental Authority applicable to Barnes or any Subsidiary, or 
  
 (iii) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to Barnes or any
Subsidiary. 
  

 17 








 2.5. Governmental Authorizations. 
  
 No consent, approval or authorization of, or registration, filing or declaration with, any Governmental Authority or any
non-governmental Person, including, without limitation, any creditor or stockholder of Barnes or any Subsidiary is required that has not been obtained in connection with (a) the execution, delivery and performance by 3031786 or Barnes of this
Assumption Agreement, or (b) the execution, delivery and performance by Barnes of the Amended Note Agreement or the Notes. 
  
 2.6. Litigation. 
  
 (a) Except as disclosed on Schedule 2.6, there are no actions, suits or proceedings pending or, to the knowledge of 3031786 or Barnes,
threatened against or affecting Barnes or any Subsidiary or any property of Barnes or any Subsidiary in any court or before any arbitrator of any kind or before or by any Governmental Authority that if adversely determined, individually or in the
aggregate, would reasonably be expected to have a Material Adverse Effect. 
  
 (b) Neither Barnes nor any Subsidiary is in violation in any respect of any term of any charter instrument or by-law and neither Barnes nor any Subsidiary is in default of any order, judgment, decree or ruling of any
court, arbitrator or Governmental Authority or is in violation of any applicable law, ordinance, rule or regulation (including, without limitation, Environmental Laws) of any Governmental Authority, which default or violation, individually or in the
aggregate, would reasonably be expected to have a Material Adverse Effect. 
  
 2.7. Existing Indebtedness. 
  
 Except as described therein, Schedule 2.7 hereto sets forth a complete and correct list of all outstanding Indebtedness of Barnes and its Restricted Subsidiaries as of June 30, 2005 (and specifying, as to each such Indebtedness, the
collateral, if any, securing such Indebtedness), since which date there has been no Material change in the amounts, interest rates, sinking funds, installment payments or maturities of the Indebtedness of Barnes or its Restricted Subsidiaries.
Neither Barnes nor any Restricted Subsidiary is in default and no waiver of default is currently in effect, in the payment of any principal or interest on any Indebtedness of Barnes or any Restricted Subsidiary and no event or condition exists with
respect to any Indebtedness of Barnes or any Restricted Subsidiary that would permit (or that with notice or the lapse of time, or both, would permit) one or more Persons to cause such Indebtedness to become due and payable before its stated
maturity or before its regularly scheduled dates of payment. 
  
 2.8. No Defaults. 
  
 No “Default” or
“Event of Default” under, and as defined in, the Existing Note Purchase Agreement exists immediately prior to the Effective Date. Upon the effectiveness of this Assumption Agreement no “Default” or “Event of Default”
under, and as defined in, the Amended Note Agreement will exist or occur. 
  

 18 








 2.9. Organization and Ownership of Shares of Subsidiaries. 
  
 (a) Schedule 2.9 is (except as noted therein) a complete and
correct list of Barnes’s active Subsidiaries, showing, as to each Subsidiary, the correct name thereof, the jurisdiction of its organization, the percentage of shares of each class of its capital stock or similar equity interests outstanding
owned by Barnes and each other Subsidiary. 
  
 (b) All of the outstanding shares of capital stock or similar equity interests of each Subsidiary shown in Schedule 2.9 as being owned by Barnes and its Subsidiaries have been validly issued, are fully paid and nonassessable and are owned
by Barnes or another Subsidiary free and clear of any Lien (except as otherwise disclosed in Schedule 2.9). 
  
 (c) Each Subsidiary identified in Schedule 2.9 is a corporation or other legal entity duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization, and is duly qualified as a foreign corporation or other legal entity and is in good standing in each jurisdiction in which such qualification is required by law, other than those
jurisdictions as to which the failure to be so qualified or in good standing would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each such Subsidiary has the corporate or other power and authority
to own or hold under lease the properties it purports to own or hold under lease and to transact the business it transacts and proposes to transact. 
  
 2.10. Private Offering by Barnes. 
  
 Neither Barnes nor anyone acting on its behalf has offered the Notes or any similar Securities for sale to, or solicited any offer to buy any of the same
from, or otherwise approached or negotiated in respect thereof with, any person other than the Noteholders, each of which has been offered the Notes at a private sale for investment. Neither Barnes nor anyone acting on its behalf has taken, or will
take, any action that would subject the issuance or sale of the Notes to the registration requirements of Section 5 of the Securities Act.
