Form of Non-Qualified Stock Option Agreement



 Exhibit 10.4 
 FORM of 
 LYDALL, INC. 
 NONQUALIFIED STOCK OPTION AGREEMENT 
 THIS NONQUALIFIED STOCK OPTION AGREEMENT (this
“Agreement”) is made between Lydall, Inc., a Delaware corporation (the “Company”), and the recipient (the “Recipient”) of a Nonqualified Stock Option granted under the Amended and Restated Lydall 2003 Stock Incentive
Compensation Plan (the “Plan”). The specific terms and conditions of the Stock Option, including the date of grant as of which the Stock Option shall be effective (the “Date of Grant”), are set forth in the award letter (the
“Award Letter”), dated                         , 20    , from the President and Chief
Executive Officer of the Company to the Recipient, this Agreement and the Plan, all of which will become binding upon the Recipient’s acceptance of the Stock Option in accordance with the terms and provisions of this Agreement. All capitalized
terms used but not defined in this Agreement shall have the same meanings that have been ascribed to them in the Plan, unless the context clearly requires otherwise. 
 1. Grant of Award. The Company hereby grants to the Recipient, pursuant to Article V of the Plan, a Nonqualified Stock Option to purchase up to the number of shares of Common Stock (the
“Stock Option”) as set forth in the Award Letter. The Stock Option is subject to the restrictions, terms and conditions set forth in the Award Letter, this Agreement and the Plan. 
 2. Type of Stock Option. The Stock Option is a Nonqualified Stock Option which does not qualify for Incentive Stock Option
treatment under Section 422A of the Internal Revenue Code of 1986, as amended. 
 3. Stock Option Price. The
purchase price of each share subject to the Stock Option is set forth in the Award Letter, such price being 100 percent of the Fair Market Value of the Common Stock on the Date of Grant. 
 4. Acceptance of Award. The Recipient shall have no rights with respect to the Stock Option unless he or she accepts the award
no later than the close of business on the date that is sixty (60) days after the Date of Grant. Award acceptance shall be completed by accessing the Company’s administrative agent’s website, BNY Mellon, (the “Administrative
Agent”) referenced in the Award Letter and following the required on-line grant acknowledgement process. 
 5.
Manner of Exercise of a Stock Option. The Administrative Agent must be used to exercise all or any portion of the Stock Option, including cashless and sell-to-cover transactions. The Administrative Agent will provide the Recipient with a
confirmation of each exercise made. The Administrative Agent will collect funds for option costs and taxes related to an exercise (as applicable), or issue the net proceeds in the case of a cashless exercise. To exercise all or any portion of the
Stock Option or to ask questions, contact the Administrative Agent. 
 The Company’s “Securities Law Compliance
Policy” requires Section 16 Officers as designated under the Securities Exchange Act of 1934, as amended, and certain designated employees to pre-clear Stock Option transactions with Lydall’s General Counsel. All employees must comply
with Lydall’s policies regarding trading of its securities by Company or any Subsidiary personnel. 







 6. Additional Terms and Conditions. 
 (a) Term of Stock Option. The Stock Option shall have a term of ten (10) years from the Date of Grant,
subject to earlier termination in accordance with the provisions of this paragraph 6 in the event that the Recipient ceases to be an employee of the Company or any Subsidiary. 
 (b) Exercise of Stock Option and Limitations Thereon. The Stock Option shall be exercised in the manner set
forth in paragraph 5 of this Agreement and exercisable subject to the limitations set forth in the Award Letter. 
 (c) Nontransferability. The Stock Option shall not be transferable by the Recipient otherwise than by will or by the laws of descent and distribution, and the Stock Option shall be exercisable, during his or her lifetime, only by the
Recipient. 
 (d) Termination by Reason of Death or Disability. If the Recipient’s employment
by the Company or any Subsidiary terminates by reason of the death or Disability of the Recipient, the Stock Option shall thereupon automatically terminate, except that the portion of the Stock Option that has vested on or prior to the date of
termination may thereafter be exercised by the Recipient or the legal representative of his or her estate for a period of one year from the date of such termination of employment or until the expiration of the stated term of the Stock Option,
whichever period is shorter. 
 (e) Other Termination. If the Recipient’s employment by the
Company or any Subsidiary terminates for any reason other than the death or Disability of the Recipient, and provided the termination was not for cause, the Stock Option shall thereupon automatically terminate, except that the portion of the Stock
Option that has vested on or prior to the date of termination may thereafter be exercised by the Recipient for a period of one year from the date of such termination of employment or until the expiration of the stated term of such Stock Option,
whichever period is shorter. Notwithstanding the foregoing, if the Committee determines that the termination of the Recipient’s employment by the Company or any Subsidiary resulted for cause, or from the Recipient’s willful act, or failure
to act, deemed detrimental to the Company or any Subsidiary, the Stock Option shall automatically terminate as of the date of such termination of employment and no portion of the Stock Option may be exercised by the Recipient after the such date.

 (f) Stockholder Rights. The Recipient shall not be entitled to any rights as a stockholder with
respect to any shares subject to the Stock Option prior to the date of issuance to him or her of any such shares. 
 7.
No Employment Rights. Nothing in this Agreement shall be deemed to: (a) confer or be deemed to confer upon the Recipient any right to continue in the employ of the Company or any Subsidiary or in any way affect the right of the Company
or any Subsidiary to dismiss or otherwise terminate the Recipient’s employment at any time for any reason with or without cause, (b) impose upon the Company or any Subsidiary any liability for any forfeiture of the Stock Option which may
result if the Recipient’s employment is terminated, or (c) affect the Company’s or any Subsidiary’s right to terminate or modify any contractual relationship with a Recipient who is not an employee of the Company or any
Subsidiary.

merger or consolidation of the Company or any Subsidiary, or any issue of bonds, debentures, preferred or prior preference stocks ahead of or affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Company or any
Subsidiary, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceedings, whether of a similar character or otherwise.
