Exhibit 10.42



RESTRICTED STOCK AGREEMENT



THIS AGREEMENT is made as of January 5, 2005 between John U. Clarke (Recipient) and NATCO Group Inc. (the Company).



1. As of January 5, 2005, the Company grants to Recipient 57,000 shares of
Common Stock, $0.01 par value (Common Stock), of the Company (the Shares) in accordance with and subject to the terms of the NATCO Group Inc. 2004 Stock Incentive Plan (the 2004 Stock Plan) and this Agreement. It
is understood that the consideration for the issuance of the Shares shall be Recipients agreement to render future services as an employee of the Company, which services have a value not less than the par value of the Shares. Recipient
acknowledges receipt of a copy of the 2004 Stock Plan and agrees that this award of Shares shall be subject to all the terms and provisions of the 2004 Stock Plan. In the event of any conflict between the terms of this Agreement and the 2004 Stock
Plan, the terms of the 2004 Stock Plan shall govern. Capitalized terms used but not defined in this Agreement have the respective meanings attributed to such terms under the 2004 Stock Plan.



2. Promptly after the execution of this Agreement by Recipient, the Company
shall cause Mellon Investor Services, LLC, the transfer agent for the Common Stock (together with its successors and assigns, the Transfer Agent), to issue a stock certificate showing ownership for the Shares in the name of Recipient
subject to the terms and conditions of this Agreement and the 2004 Stock Plan. The Shares shall be issued from Common Stock reserved for issuance pursuant to the 2004 Stock Plan as grants under such plan (Plan Shares). The certificate or
certificates evidencing the Shares subject hereto shall be delivered to and deposited with the Secretary of the Company as Escrow Agent in this transaction. Such certificates are to be held by the Escrow Agent until termination of the Restricted
Period, at which time they shall be released by said Escrow Agent to Recipient. All certificates representing any Shares subject to the provisions of this Agreement shall have endorsed thereon the following legend:



The shares represented by this certificate are subject to an agreement
between the Company and the registered holder, a copy of which is on file at the principal office of the Company.



3. During the Restricted Period (as defined below) for the Shares, Recipient shall not sell, assign, exchange, transfer, pledge, hypothecate or otherwise
dispose of, transfer or encumber any of such Shares. This prohibition against transfer and the obligation to forfeit and surrender Shares to the Company as provided herein are referred to as the Forfeiture Restrictions. A breach of the
terms of this Agreement shall cause a forfeiture of the Shares. During the Restricted Period, Recipient shall have all the rights of a shareholder with respect to the Shares except for the right to transfer the Shares. Accordingly, Recipient shall
have the right to vote the Shares and to receive any cash dividends paid to or made with respect to the Shares.



4. Recipient represents that the Shares are being acquired for investment and that Recipient has no present intention to transfer, sell or otherwise
dispose of the Shares, except in compliance with applicable securities laws, and the parties agree that the Shares are being acquired in accordance with and subject to the terms, provisions and conditions of this Agreement and the Plan. Recipient
agrees that (a) the Company may refuse to register the transfer of the Restricted Shares on the stock transfer records of the Company if such proposed transfer would constitute a violation of the Forfeiture Restrictions or any applicable securities
law and (b) the Company may give related instructions to the Transfer Agent to stop registration of the transfer of the Restricted Shares.



5. The Forfeiture Restrictions shall lapse as to 100% of the Shares on the third anniversary date of this Agreement, provided that Recipient has
continuously served as an employee of the Company from the date of this Agreement until such date. Notwithstanding the foregoing, the Forfeiture Restrictions shall lapse as to all of the Shares on Recipients termination of employment due to
his death or disability (as determined by the Committee) or upon the occurrence of a Corporate Change and may earlier lapse as to all of the Shares pursuant to Section VIII of the 2004 Stock Plan. A certificate for all Shares granted pursuant to
this Agreement will be issued to Recipient following such date of release, or, at Recipients election, may be transferred in book entry form to Recipients brokerage account (subject to any adjustment to withhold Shares to pay taxes as
provided below). Any period during which Shares are subject to restriction under this Agreement is referred to as the Restricted Period. In the event of termination of Recipients service as an employee of the Company for any reason
during the Restricted





---

Period, other than as a result of Recipients death or disability or upon occurrence of a Corporate Change, all Shares with respect to which the
Forfeiture Restrictions that have not lapsed in accordance with the preceding provisions of this paragraph, for no consideration, shall be immediately forfeited to the Company.



6. The Company shall be required to withhold the amount of taxes required to satisfy any applicable federal, state and local
tax withholding obligations arising from the lapse of restrictions on the Shares. Recipient may elect to satisfy any such tax obligation in cash or by authorizing the Company to withhold from the Shares issued to Recipient as a result of the lapse
of the restrictions on Shares, the number of whole shares of Common Stock required to satisfy such tax obligation, the number to be determined by the Fair Market Value of the Shares on the date of the lapse of the restrictions on Shares. If
Recipient elects to withhold shares of Common Stock to satisfy any such tax obligation, Recipient shall pay in cash any obligation that remains after the application of whole shares that is less than the value of a whole share.



7. Recipient understands that the Company will, and Recipient hereby
authorizes the Company to, issue such instructions to the Transfer Agent as the Company may deem necessary or proper to comply with the intent and purposes of this Agreement. This instruction serves as a stock power by Recipient to the Company with
respect to the Shares during the Restricted Period, which stock power shall expire at the end of the Restricted Period.



8. After the Forfeiture Restrictions have lapsed with respect to the Shares as provided above, for so long as Recipient remains an employee of the Company
or a subsidiary, Recipient is required to retain at least one-third of the Shares for a period of three years following lapse of the Forfeiture Restrictions applicable to such Shares, unless the Governance, Nominating & Compensation Committee of
the Companys Board of Directors (or successor committee under the 2004 Stock Plan) shall approve a lower or no retention threshold a on a case-by-case basis after a showing of demonstrated need or special circumstance.



9. This Agreement shall be binding upon and inure to the benefit of the
parties hereto and the successors and assigns of the Company and the successors, assigns, heirs and personal representatives of Recipient.



10. No provision contained in this Agreement shall in any way terminate, modify or alter, or be construed or interpreted as terminating, modifying or
altering any of the powers, rights or authority vested in the Committee pursuant to the terms of the 2004 Stock Plan, including, without limitation, the Committees rights to make certain determinations and elections with respect to the
Restricted Shares.



11. This Agreement shall not be deemed to
(a) confer upon Recipient any right with respect to continuation of employment with the Company or a subsidiary or (b) affect the terms and conditions of any other agreement between the Company and Recipient except as expressly provided herein.



12. This Agreement shall be governed by the laws of the State
of Delaware applicable to agreements made and to be performed entirely within such State. This Agreement may not be altered, modified, changed or discharged, except by a writing signed by or on behalf of both the Company and Recipient. This
Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original, but all of which together will constitute one and the same Agreement.



IN WITNESS WHEREOF, the parties have signed this Agreement as of the date first written above.
